Phantom Limb Syndrome

Sep 30 2011 Published by admin under Uncategorized

What is Phantom Limb Syndrome?

This is the awareness of feelings, frequently together with pain, in an appendage which has been removed. Individuals with this syndrome feel this limb just as if it were involved still with the body and the brain still gets communications from nerves which formerly passed sensations from the absent limb.

Symptoms

Symptoms and signs happen in individuals who have experienced the removal of a limb and individuals who are born minus a limb. These symptoms or signs are felt in a limb that doesn’t exist.

Symptoms and signs can include:

  • Pleasure
  • Pain – most common
  • Feelings of articles of jewelry or clothing
  • Feelings as if the limb were still attached as well as operating routinely

Causes

The precise cause of this syndrome is not known. Apparently, the feelings are caused by the brain’s effort to rearrange sensual knowledge after the removal of the limb. The brain might basically be “rewiring itself” in order to correct the change to the body.

Risk factors that can raise the odds of developing this syndrome include:

  • Pain before amputation. If pain was in the limb prior to removal, the individual is most likely to feel phantom pain following removal
  • Blood clot in the removed limb
  • Damage previously to the peripheral nerves or spinal cord which worked with the affected limb
  • Children less commonly than adults

After an amputation, it is vital to inform the physician if the individual is feeling pain or other sensations. The earlier treatment is begun generally the chances of success improve.

No medical tests can help in diagnosing phantom sensations. The physician will do a medical history, a physical exam and will want to know about symptoms, circumstances and signs that have happened prior to as well as after the limb removal.

Treatment

Auspiciously, the majority of cases of this syndrome are infrequent and brief. For individuals who do feel pain that is persistent, the treatment may become challenging.

Medications

Certain drugs which are frequently used to treat this syndrome consist of:

  • Antidepressants – used for treatment of depression, but can be supportive in pain with phantom limb when used at doses that are low
  • Chlorpromazine – used for treating schizophrenia, but can be supportive in this situation also
  • Anticonvulsants – used in controlling seizures, but can also be supportive in this situation
  • Opioids – powerful pain killers – for instance morphine
  • Baclofen – relaxes muscles and are used in treating pain of nerve damage

Electrical Nerve Stimulation

In some cases, electrical stimulation of the nerve can be tried. Examples consist of:

  • TENS or “transcutaneous electrical nerve stimulation” – tiny current of electricity is sent thru the skin to points along the pathway of the nerve.
  • “Transcranial magnetic stimulation” – magnetic pulse that is strong is sent thru the scalp into the brain.
  • Stimulation spinal cord – electrode inserted and small electric current is sent to the spinal cord for pain relief.

Other Approaches – other approaches can include:

  • Regional sympathectomy – surgical method where selected nerves near the spinal cord are interrupted affecting the awareness of localized pain.
  • Relaxation and meditation techniques
  • Hypnosis
  • Biofeedback
  • Massage
  • Exercise

Wolfram Syndrome

Sep 29 2011 Published by admin under Uncategorized

What is Wolfram Syndrome?

This is a syndrome that is a genetic link of “childhood/juvenile onset diabetes mellitus” as well as “progressive onset optic atrophy. Every individual having this syndrome has:

  • Degeneration of optic nerve known as optic atrophy
  • Childhood/Juvenile-onset diabetes mellitus

Additionally, approximately 70% – 75% of individuals affected will also have diabetes insipidus and approximately 2/3 develops what is referred to as “auditory nerve deafness:”

This syndrome is referred to as “WS”, or DIDMOAD that refers to:

DI – Diabetes insipidus
DM – Diabetes Mellitus
OA – Optic atrophy
D – Deafness

This syndrome was first defined in four (4) siblings by Dr. Don J. Wolfram, M.D. in 1938. This syndrome disturbs the brain specially the brain stem as well as the CNS or central nervous system.

Symptoms

This syndrome is not an easy problem to diagnose. The majority of individuals will have this disorder for years before an accurate diagnosis is made.

Some of the signs, symptoms or complaints that an individual might have or will see in their child:

  • Type-1 Diabetes, normally beginning between the ages of 5 to 15
  • Frequent and unusual urination in large amounts, combined with being constantly thirsty.
  • Bedwetting will begin again after night training has already been successful
  • Visual impairment beginning with wearing glasses but increasing rapidly
  • Color blindness – socks will never match an outfit or the lawn might have many missed patches of grass after cutting.
  • Reacting of the iris in the eye that is slow – even in bright lights pupils never go pinpoint
  • It becomes evident that high frequency hearing loss or tonal deafness has developed
  • Easy to get upset or emotionally agitated

The challenge with this syndrome is that the symptoms are in the beginning very mild. Any one of them is not difficult to overlook or to treat as an individual abnormality. But the secondary developing complications can definitely rationalize any serious worries. WS is a degenerative and progressive disease – meaning it will continue to get worse with time.

Causes

The cause of this disorder is a genetic mutation. The incidence of individuals who have this genetic trait in the United States is approximately one (1) %. Those individuals who have this recessive trait will not display the complete range of symptoms of WS. They are subject to an inflated rate of numerous methods of mental illness. It is merely when both parents have this trait recessively who have offspring who the WSF1 gene as a dominant affect. In these families the likelihood of getting the dominant trait is one (1) in four (4) for every birth. Multiple cases within a single genetically predisposed family are not uncommon.

In the UK it is projected that one (1) person in every 700,000 have this disorder. A United State scientist, Dr. Michael Swift, believes that the rate of individuals affected is much more common than has been reported earlier. No matter what the actual incident figures are, WS is a rare genetic disorder. It is currently understood to be the effect of either mitochondria or nuclear gene dysfunction. The “autosomal recessive trait” appears in both females and males with the same frequency.

Treatment

Diabetes mellitus is normally the symptom of WS which will require medical management first in the progress of WS. There is not any conventional advancement of this syndrome and other difficulties that may lead the start of DIABETES MELLITUS. With diabetes mellitus, the food eaten is treated by gastric fluid in the stomach into blood sugar or glucose. Blood sugar is the body’s major source of energy used by the body cells to function. For these cells to be able to use this blood sugar, a hormone that is produced naturally by the pancreas, insulin, is needed. As soon as the pancreas stops creating the precise quantity of insulin that is required for the use of blood sugar the spare blood sugar is distributed by the kidneys into urine and emptied from the body. Extreme blood sugar is identified as diabetic acidosis and may cause unconsciousness, coma and loss of life. The problems an individual DIABETES MELLITUS may have can include:

  • Frequent thirst and urination
  • Slow healing
  • Weight loss or lack of weight gain or growth with children
  • Itching
  • Constant hunger
  • Dryness of skin

The management of DIABETES MELLITUS in WS individuals is the same as in the management of DIABETES MELLITUS in individuals who do not have WS. This includes:

  • Daily injections of insulin
  • Diet controlled
  • Exercise to use up glucose
  • Frequent testing of glucose levels

Diabetes Insipidus – Individuals who develop diabetes insipidus will drink enormous amounts of fluid and void diluted urine frequently. This leads to:

  • Dehydration
  • Weakness
  • Dry mouth
  • Constipation
  • Dry skin

When individuals have this form of diabetes, the gland known as hypothalamus creates an abnormal quantity of hormone for anti-diuretic. DI or Diabetes insipidus doesn’t have anything to do with the amount of blood sugar or insulin. This problem has also been recognized to occur in individuals with head trauma that is severe and completely unrelated to WS.

This type of diabetes is treated normally by Desmopressin Acetate nasal spray. This medication is also available in tablet as well as injectable form. In 1989 this treatment was approved by the FDA for the treatment of Diabetes Insipidus. This medication offers heightened anti-diuretic action with minimal side effects on the blood system or the smooth muscles of individuals with Diabetes Insipidus.

Blindness/Low vision – the most discernible feature of WS is iris of the eye becoming dilated. Even when in light that is bright, the iris will stay wide and respond slowly. The continuing loss of the nerves of the optic that connect the eye to the brain is what allows this to happen. This is identified as Optic Atrophy. Any eye doctor will typically see a saucer shaped void that appears white or grayish. Some reports specify that the optic nerve seems pale pink. This can occur at any age but normally before age 12. There is no known treatment at this time for this condition.

Loss of vision in WS individuals may also be due to Diabetic Retinopathy. This is a condition of retina tissues that are light sensitive caused by continued blood sugar levels that are high. It can lead to visual damage or blindness. Blood sugar levels that are normal may help reverse changes in the small blood vessels of the eye. If blood sugar levels can be maintained in the normal range, this problem of diabetes may be evaded.

Deafness/hearing impairment – is the last major symptom of WS but not automatically last to become obvious. Loss of hearing may go from the loss of those tones that are high pitch to severe sound loss. There may as well be complications such as dizziness or ataxia. This might be due to failure of nerves to properly transmit data from the ear to the brain.

Diagnosis

WS is not only a genetic disease that is rare but also has a variety of disorders often making this syndrome hard to diagnose. The typical symptoms may not all appear in all individuals. Normally diabetes mellitus as well as optic nerve atrophy are the clinical features that are the most consistent. A diagnosis of WS is clinically founded on diabetes requiring insulin as well as “bilateral optic nerve atrophy”. There are genetic tests which can also be run to confirm this diagnosis in most individuals. But there are numbers of individuals with WS where there is no mutation that is identifiable.

Prognosis

The life expectancy of individuals diagnosed with this syndrome is approximately 30 years.

Complications

Complications of this syndrome usually include the urinary tract as well as seizure disorders. Approximately 2/3 of individuals will experience renal problems in their 20s with a similar proportion developing neurological complications in their 30s.

Liddle’s Syndrome

Sep 27 2011 Published by admin under Uncategorized

What is Liddle’s Syndrome?

This syndrome is an autosomal dominant form of hereditary hypertension or chronic high blood pressure and hypokalemia which is an abnormally low concentration of potassium ions in the blood. In other words, this is a genetic and rare disorder where the kidneys evacuate potassium but keep too much sodium and water, leading to high blood pressure. This syndrome could have onset in infancy, but children often show no signs of the syndrome.

Symptoms

This disorder does not always cause symptoms. But if it does, symptoms like hypertension often begin early. Some individuals also have low levels of potassium in the blood.

Some of the symptoms of Liddle syndrome include:

  • Metabolic acidosis – which is a process that when left unrestrained leads to blood pH that is too low due to amplified manufacture of H+ by the body or the failure of the body to develop bicarbonate (HCO3-) in the kidney.
  • Hypertension
  • Low rennin level
  • Reduced aldosterone secretion
  • Low blood potassium level
  • Fatigue
  • Weakness
  • Muscle weakness
  • Heart palpitations
  • Constipation
  • Shortness of breath
  • Decreased exercise capacity and tolerance
  • Abdominal bloating

Children with this syndrome are normally asymptomatic. The first suggestion of this syndrome often is the discovery of hypertension thru a routine exam. Since this syndrome is very rare it might only be considered by the child’s doctor after the child’s high blood pressure does not react to antihypertensive medication.

When allowing for symptoms of Pseudoaldosteronism, it is also important to consider Pseudoalosteronism as possibly being caused by some other medical condition. The Disease Database lists the following medical problems that could be causing the Pseudoaldosteronism such as:

  • Alkalosis, metabolic
  • Hypertension, systemic
  • Hyopkalaemia
  • Renin levels low – serum

Causes

Liddle syndrome develops when the kidneys expel potassium but hold extreme amounts of water and sodium and lead to elevated blood pressure. The gene causing this syndrome is dominant, meaning that if any individual has this mutated gene, then their children have a 50% chance of receiving this defective gene.

Liddle syndrome is linked with low plasma renin action, metabolic alkalosis owing to hypokalemia and hypoaldosteronism – or low secretion of aldosterone.

This is only one of numerous circumstances with this uncommon set of features known communally as pseudohyperaldosteronism. High blood pressure caused by this syndrome often starts in infancy.

Liddle syndrome contains atypical function of the kidneys, with additional resorption of sodium as well as the loss of potassium thru the renal tubule, and is frozen with blend of diet that is low in sodium and diruetic drugs that are potassium-sparing.

Diagnosis

Evaluation of a pediatric hypertensive child typically includes analysis of the electrolytes of the blood as well as a level of aldosterone in the system, as well as various other tests. With Liddle syndrome, the serum sodium is normally elevated, the serum bicarbonate is high and the serum potassium is lower. But the physician needs to make certain that the findings are not from other conditions such as hyperaldosteronism which is also a very rare problem causing hypertension in infants. Primary hyperaldosteronism which is also referred to as Conn’s syndrome is also caused by adrenal tumor that is aldosterone-secreting or adrenal hyperplasia. Levels of aldosterone are high with hyperaldosteronism, but are low to normal in Liddle syndrome.

Treatment

The treatment for this syndrome is with low salt or low sodium diet and a diuretic that is potassium-sparing and blocks the sodium channel directly. Diuretics that are effective with this syndrome include triamterene and amiloride; drugs that block the sodium channel which stops the disease from growing.

The drug spironolactone is not operative due to the fact that it works by the regulation of aldosterone and Liddle syndrome does not react to this directive.

Multiple Organ Dysfunction Syndrome

Sep 21 2011 Published by admin under Uncategorized

What is Multiple Organ Dysfunction Syndrome?

This syndrome also referred to as MODS is a progressive condition normally characterized by combined failure of several major organ systems in a critically ill individual that can make it impossible to maintain homeostasis without some type of medical intervention and which is normally a complication of sepsis and is also a major factor in predicting mortality. It normally involves the collapse of at least two organ systems. MODS may include any of these listed vital systems:

  • Acute renal or kidney system
  • Liver system
  • Heart system
  • Respiratory system
  • Blood system
  • Neurologic system

Symptoms

The following six organ systems characterize MODS and they include:

  • Respiratory
  • Renal
  • Cardiovascular
  • Neurologic
  • Hepatic
  • Hematologic

The signs and symptoms of end-organ dysfunction in the above organ systems consist of:

Lung or respiratory system – will show a dysfunction of normal exchange of gas, revealed mainly in “arterial hypoxemia” which is insufficient oxygen getting into the blood system. Many pathologic features add to this impaired gas exchange.

Kidney or renal system – is revealed in the impairment of the normal selective excretory function first in oliguria or low output of urine despite adequate intravascular volume, but later in a rising creatinine level and electrolyte and fluid problems of sufficient magnitude that in some cases dialysis may be required.

Heart and cardiovascular system – dysfunction of this system consist of abnormalities predisposed to impaired delivery of oxygen and therefore contribute to the injury of other organ systems.

Hepatic system – dysfunction of the hepatic system is reflected in excess bilirubin circulating in the blood as well as lack of bile flowing from the liver.

Neurologic system – there is an altered level of consciousness, which is reflected in the reduction in the Glasgow Coma Score which is the scale of consciousness of a individual due to multiple causes

Hematologic system – the most widely cited manifestation of dysfunction of the blood system consist of thrombocytopenia which in critical illness is cause by a multiple of factors.

Causes

This syndrome normally occurs as a secondary phenomenon. The causes for this condition are an unrestrained inflammatory reaction or infectious response due to a severe injury or illness. Septic shock or shock which is caused by an infectious cause is the most common reason for MODS. Trauma that is severe with tissue and muscle damage also can cause this condition. There are some cases of prolonged shock-like conditions from a heart attack that is massive and can cause this syndrome.

Cardiopulmonary Failure

This is the combined failing of the respiratory and cardiovascular systems and normally these systems fail together as they function closely with each other. Cardiac or respiratory failure may in some case be the beginning disease state. With failure of the respiratory system, such as with overwhelming sepsis or pneumonia, the blood is not oxygenated properly and the muscle of the heart cannot function properly. Deprived of acceptable oxygenation, the kidneys and the liver do not perform well either but is not as sensitive to low levels of oxygen as is the heart.

Whenever the heart starts to fail, it cannot properly pump blood in the body and the backing up of blood creates fluid leaking into the tissues of the lungs causing pulmonary edema where basically the lungs fill with fluid. This pulmonary edema restricts the lungs even further from providing oxygenated blood to the rest of the body. This results in a brutal cycle that usually will end in cardiopulmonary collapse and death.

Shock

In those cases of septic shock, the pressure of the blood can become so low that the liver, kidney, lungs as well as the heart do not receive blood flow that is adequate. Unless quickly corrected, all of the body’s organs and systems will shut down, resulting in an almost 100% mortality rate.

Treatment

Presently there is no medical agent that reverses organ failure. Therapy is limited therefore to only supportive care, such as safeguarding hemodynamics and respiration. The principal aim is to maintain adequate tissue oxygenation. Beginning enteral nutrition within thirty-six hours of the admission to an intensive care unit has been shown to reduce complications caused by infections.

Prognosis

The mortality rate varies from around 30% to 100% with the chance of surviving diminishing as the number of organs involved increases. Since approximately the 1980s this mortality rate has not changed.

In Children

More data is needed regarding children with MODS. MODS that is secondary is much less likely than primary MODS with children. It is linked with an increased morbidity and mortality rate and it is believed that distinct pathophysiologic mechanism are involved with these two conditions.

Pathophysiology

Sepsis is believed to be the major cause of MODS and still remains a great concern due to the associated high mortality and morbidity rate. In recent years, there have been important advances made in the pathophysiology of sepsis as well as sepsis shock and its treatment. Both septic shock and severe sepsis are the end results of very complex interactions between infection organisms as well as various elements of the host response. The first and main feature to starts failure first is the cardiovascular system, which begins first and the failure of this system begins to affect all the other systems. Improvement in result with sepsis is based on early recognition of this progression and starting operative therapies. The faster that cardiovascular problems are noted the better the outcome. The window of time for intercession is really short and treatment needs to be started promptly in order to control the source of infection and restore homoeostasis of the blood flow.

Severe Acute Respiratory Syndrome

Sep 21 2011 Published by admin under Uncategorized

What is Severe Acute Respiratory Syndrome?

Commonly referred as SARS, this is a very contagious and often fatal illness of the respiratory system triggered by a virus. SARS was reported first in China during November of 2003. It migrated globally over numerous months carried by travelers who were unaware of this disease before the outbreak eventually ended.

SARS is a clear example of how fast an infection can spread in the highly mobile world that is interrelated. The epidemic of SARS also displayed that support between international health professionals can successfully contain the spread of a disease. Since 2004, the known occurrence of transmission of SARS has fallen to zero globally.

Symptoms

Typically SARS starts with signs and symptoms that are flu-like – chills, fever, aching muscles and sometimes diarrhea. Afterward in about seven (7) days, symptoms and signs include the following hallmark symptoms:

  • Dry cough
  • Fever of 100.4 F or higher
  • Shortness of breath

The symptoms that are most common include:

  • Chill and shaking
  • Cough – starting two (2) to three (3) days after other symptoms
  • Headache
  • Fever
  • Muscle aches

Symptoms that are less common include:

  • Cough producing sputum or phlegm
  • Dizziness
  • Vomiting and nausea
  • Diarrhea
  • Sore throat
  • Runny nose

In numerous individuals the symptoms of lung problems becomes worse thru the 2nd week of this illness, often after the fever has gone.

If an individual believes they have SARS are have been exposed to SARS it is vital to see a primary care physician immediately. SARS is a very severe illness that can lead to death.

Causes

SARS is triggered by one of the viruses of the coronavirus family – this same family of viruses that may triggered the common cold. It is thought that the 2003 epidemic began when the virus migrated from smaller mammals in China.

Whenever anyone who has SARS sneezes or coughs droplets that are infected spray in the air. An individual can catch the SARS virus by breathing in or simply touching these particles. The virus causing SARS can live on tissues, hands as well as on other surface areas for up to six (6) hours in these drops and for up to three (3) hours even after the drops have dried up.

While drops spread thru close contact causes the majority of the earliest SARS cases, it can also be spread by hand contact as well as other objects that these drops have touched. Airborne transmission is also a possibility in some cases. Live virus has even sometime been seen in the stool of individuals with SARS, where the virus has been shown to live for as much as four (4) days. This virus is able to live for months or even years when the temperature of the environment is below freezing.

Becoming infected and then getting sick again or re-infection is common with coronavirus. This is also the case with the SARS virus.

Usually symptoms transpire approximately two (2) to ten (10) days after contact with the virus. There have also been some cases where the illness starts sooner or later after first contact. Individuals with symptoms of active illness are contagious but it is not known how long that individual can be contagious prior to as well as after symptoms appear.

Treatment and Prevention

Individuals who are believed to have SARS need to be checked as quickly as possible by a healthcare provider. If an individual is believed to have SARS, it is important for them to be quarantined in the hospital.

Management will consist of:

  • Antiviral drugs
  • Antibiotics to guard against bacteria causing pneumonia
  • High steroid doses to reduce any swelling in the lungs
  • Breathing support such as mechanical ventilation, oxygen or chest therapy

In those cases that are extremely serious, the liquid portion of the blood drawn from individuals who have recuperated from SARS is given for treatment. There is no definitive indication that these treatments work. But there is strong evidence that the antiviral drug, ribavirin, does not work.

The rate of death from SARS during the last epidemic was nine (9) % to twelve (12) % of those who have been diagnosed. In individuals over the age of 65, the death rate was much higher than 50%. This illness appears to be milder in younger individuals.

Many more individuals become so sick that they needed assistance breathing. And even more individuals had to be put into the hospital intensive care units.

Policies from public health have been very effective in controlling outbreaks. Many countries have stopped the epidemic in their own citizens. All countries need to continue to be careful to keep SARS under control.

Complications of SARS include:

  • Liver failure
  • Respiratory failure
  • Heart failure

Reducing any contact with individuals who have SARS lowers the risk of this disease. Avoid traveling to places where there is an uncontrolled outbreak of SARS. Avoid direct contact with individuals who have SARS for at least 10 days after fever and other symptoms are gone.

Other precautions to use include:

  • Use hand hygiene. Clean hands or wash them with an instant hand sanitizer that is alcohol-based.
  • Do not share drink, food, or utensils
  • Cover the mouth and nose when sneezing or coughing.
  • Clean surfaces that are commonly touched with a disinfectant EPA-approved disinfectant

In some situation goggles and masks might be beneficial in preventing the disease to spread. Gloves can be used when handling any items that can have infected drops.

Transmission

The SARS virus is not really easily transmissible outside of definite settings. For a local outbreak that is major to happen there needs to be:

  • An infectious patient
  • A close community or “tribe”, for instance healthcare workers, travel groups, military population, and religious gatherings.

This gives confidence that SARS cannot be spread in a completely uncontrolled method in the community.

The “ideal” transmission conditions for SARS look to be:

  • Patient is highly infectious, shedding huge quantities virus
  • Patient has co-morbidities that mask the signs and symptoms of SARS
  • Patient is admitted to hospital with contact to multiple persons due to the diagnostic workup, possibly including high-risk procedures such as endotracheal intubation, bronchoscopy, use of nebulizers, etc.

Job Syndrome

Sep 21 2011 Published by admin under Uncategorized

What is Job Syndrome?

This syndrome is a very rare immune deficient disorder with an occurrence of approximately one  in a million. Currently there are only about 250 cases reported in the medical literature. There are probably many more living hidden in the dirt and dust of third world countries.

Job syndrome is categorized by an atypically high level of an immune system protein known as immunoglobulin E or IgE in the blood. IgE generates an immunity reaction against any foreign substance in the human body, such as parasitic worms, and plays a role in allergies. It is not known why individuals with this syndrome have such an extraordinary level of IgE.

Job syndrome can distress any individual female or male of any age group and race but is overwhelming in children between the ages of one to ten and can lead to the slow death of the individual.

Job Syndrome Symptoms

The symptoms and signs listed below have been mention in some of the medical literature:

  • Recurrent suppurative infections
  • Lymphadenitis
  • Pulmonary infections
  • Conjunctivitis
  • Underdeveloped mid-face
  • Coarse facial features
  • Prominent nose
  • Osteoporosis
  • Premature fusion of skull bones
  • Osteogenesis imperfecta
  • Guilt
  • Depression
  • Increased number of eosinophils in blood
  • Mouth fungal infections
  • Chronic eczemoid rash
  • Nail bed fungal infections
  • Nasal discharge
  • Fever
  • Leukocytosis
  • Large skin abscesses
  • Sinus infections that are recurrent
  • Recurrent bronchitis
  • Recurrent pneumonia
  • Reduced bone density
  • Frequent fractures
  • Persistent skin abscesses and infection
  • Recurrent sinus infections
  • Eczema

Symptoms of this condition normally occur close to birth and in early infancy, beginning with a distinctive rash. The infant will be prone to skin as well as lung infections by bacteria and viruses and the development of neurological symptoms. This syndrome also weakens bones, making them prone to fracture and can cause dental problems. Individuals might not lose their primary teeth when their adult teeth come in. Job syndrome is linked with joints hypermobility as well as scoliosis of the spine.

Job Syndrome Causes

The cause of Job syndrome is owed to the mutations or alterations in the STAT3 gene. This is the gene that delivers instruction for creating a protein that plays a vital role in numerous body systems. This protein is intricate in numerous cellular functions, as well as cell division and growth, movement of cells as well as cells self-destruction. To carry out these functions, the STAT3 protein fastens to DNA and aids in guiding the activity of precise genes.

Very little is known about how the STAT3 mutations affect the cells and tissues of the body. Deviations in this gene alter the meaning and assembly of the STAT3 protein, harming its capability to control the action of other genes. This defective protein interrupts cellular functioning such as the regulations of the immune system. The resulting immune system anomalies make individuals with Job syndrome extremely susceptible to infections. This protein is involved also in the creation of cells that break down bone tissue, which helps clarify why STAT3 alterations cause the dental and skeletal anomalies distinctive of this syndrome.

When Job syndrome is not instigated by STAT3 modifications, the genetic cause of the syndrome is unknown.

Job Syndrome Diagnosis

If a physician suspects that a child or older individual might have this syndrome, there are several diagnostic tests that can be run in order to look for key signs. Because this condition is rare, a physician might miss it in the beginning unless she/he has had any experience with patients who have this syndrome. After the diagnosis of Job syndrome is made, the child’s parents might find it to be of help to discuss this condition with a counselor or specialist in genetics to learn as much as possible about the essentials of their child’s case. Normally patients with this syndrome need treatment or management from physicians in a number of different specialties and may also require some adjustments in order to reduce any risks of infections as well as fractures linked with this condition.

Physicians will often do an eye exam in order to look for any signs of the syndrome known as dry eye. Thru the physician exam, physicians will also be looking for osteomyelitis – acute or chronic bone infection, recurrent infections of the sinus and curvature of the spine. Abscesses of the lungs can be found using x-ray of the chest. Other diagnostic tests may include:

  • Serum globulin electrophoresis – shows levels of IgE in the blood
  • Absolute eosinophil count
  • CT scan
  • X-ray of the sinuses
  • Total blood count with blood cell differential
  • Cultures of the infected site
  • Blood tests which allow the physician to explore elements of the immune system

Job Syndrome Treatment

The goal of treatment for this genetic disorder is to manage the recurrent infections that often occur. Antibiotic drugs are the most commonly used. Anti-viral drugs and anti-fungal medications may also be advantageous in many cases. Abscesses often will require surgery in order to be drained. Gamma globulin given intravenously may be used to help to temperately strengthen the immunity system during infections that are quite severe.

Individuals with eczema might benefit from lotions and creams that are able to moisturize the skin. They might also benefit from eluding anything that is identified to irritate their skin. Patients who suffer with bone fractures will be treated as needed with splinting, casting and medication for inflammation and pain. Those who have problems with teeth defects might need extra dental care.

Mortality

The bulk of patients with Job syndrome have severe pulmonary and cutaneous infections and most individuals have numerous bone fractures as well as scoliosis. The mortality rate is high due to systemic infections.

Klippel-Feil Syndrome

Sep 20 2011 Published by admin under Uncategorized

What is Klippel-Feil Syndrome?

Back in 1912, Klippel as well as Feil individually made the first portrayals of Klippel-Feil syndrome. They both described a patient with a webbed, short neck; diminished “range of motion” or ROM in cervical spine; and a hairline that is low. Feil consequently categorized this syndrome into three (3) categories:

  • Type I – immense merging of cervical spine
  • Type II – merging of one (1) or two (2) vertebrae
  • Type III – the existence of lumbar and thoracic abnormalities linked with Type I or Type II syndromes

Symptoms

Below is a list of symptoms and signs of Klippel-Feil syndrome:

  • Hairline that is low
  • Short neck
  • Neck vertebrae fused
  • Upper spine restricted mobility
  • Spina bifida
  • Scoliosis
  • Anomalies kidney
  • Anomalies of rib
  • Respiratory problems
  • Cleft palate
  • Heart malformations
  • Abnormalities of head
  • Abnormalities of face
  • Abnormalities of skeleton
  • Abnormalities of sex organ
  • Brain abnormalities
  • Abnormalities of muscles
  • Abnormalities of brain
  • Abnormalities of spinal cord
  • Abnormalities of arm
  • Abnormalities of leg
  • Abnormalities of finger
  • Cervical nerve palsy
  • Cranial nerve palsy
  • Synkinesia
  • Deafness
  • Mental deficiency
  • Ventricular septal defect
  • Sprengel anomaly
  • Restricted movement of neck
  • Posterior fossa dermoid cysts

Klippel-Feil Syndrome Causes

This syndrome is thought to occur very early in development of the fetus due to cervical vertebrae not segmenting as normal. The precise way these defects are triggered is not known.

While the majority of cases of this syndrome occur unexpectedly, there have been some studies of this syndrome that shows a configuration of heritage within a family. In certain cases, maternal alcoholism and ensuing fetal alcohol syndrome appear to be linked with Klippel-Feil syndrome.

Some individuals with this syndrome have no signs or symptoms. Those who have more minor degrees of fusion may live totally normal lives and are involved in all undertakings. They may not have any awareness that they have any abnormality at all. Individuals with fusion which is most severe will obviously be impaired in terms of the neck mobility. Several individuals may have to deal with torticollis or wry neck, which is a complaint where the muscles in the neck pull the neck to one side. When the spinal cord is restricted by vertebrae abnormalities, neurological symptoms such as numbness, weakness, tingling can result.

30% to 40% of all individuals with this syndrome have significant abnormalities structurally of the urinary tract. These can lead to chronic kidney infections referred to as pyelonephritis and a risk that is high of kidney failure.

Klippel-Feil Syndrome Treatment

The team that will manage treatment depends on the degree of disability that is brought on by the defects to the vertebral and the occurrence of any associated difficulties. With those individuals only affected mildly, an orthopedic surgeon and a pediatrician can work together in order to reach a diagnosis. In cases that are more severe, a neurologist or neurosurgeon may need to be involved also. Dependent on other body systems involved a cardiologist, urologist, orofacial surgeon and nephrologist may all be consulted. An audiologist may also consult about issues with hearing. An occupational and physical therapist may be helpful in those issues involving mobility and ability to tend to the activities of daily living.

Individuals who are only mildly affected may need no treatment. Other individuals might need surgery in order to improve stability, correct scoliosis, and improve any constriction of spinal cord. Dependent on the degree of scoliosis is when a brace can be helpful.

Physical therapy may be supportive in order to improve mobility and strength. Occupational therapy may help the most severely limited individuals learn how to better do daily activities of living, despite limitations of condition.

Life Expectancy

Difficulties connected with this syndrome normally do not advance earlier than the age of 25 years and can in some cases be treated surgically. Individuals with this syndrome usually have a lifespan that is normal. Actions that might hurt the neck should be evaded.

Dubowitz Syndrome

Sep 19 2011 Published by admin under Uncategorized

What is Dubowitz syndrome?

This is a development and genetic disorder that involves multiple inherited abnormalities including but not necessarily narrowed to:

  • Short stature or failure to grow
  • Unusual but distinctive facial features
  • Small head
  • Mild mental retardation
  • Eczema in at least one-half of the cases

Organ systems affected are multiple and this disorder is random and very adaptable in its appearance. Symptoms might be detected while the fetus is intrauterine as well as neonatally.

This syndrome was defined first by physician Dr. Victor Dubowitz in 1965. This disorder which is genetic causes retardation of growth both before and after birth. It is mostly diagnosed thru the distinct facial structures of individuals who are affected.

This syndrome may not be as rare as it was once believed. It is believed that it might only be a case of this disorder being under diagnosed. The awareness of this disorder is simply not enough to appropriately diagnose everyone who has it and less severe cases usually go undiagnosed. The incidence of this disorder that has been established only amounts to approximately 142 cases worldwide.

Dubowitz Syndrome Symptoms

This list of symptoms and signs cited in various medical literature includes the symptoms below:

  • Low birth size
  • Fetal growth retardation
  • Low birth weight
  • Small head circumference
  • Growth retardation
  • Hyperactivity
  • Osseous maturation retarded
  • Short attention span
  • Shyness
  • Mental retardation mild to severe
  • Stubbornness
  • Short attention span
  • Reduced muscle tone
  • Small face
  • Supraorbital ridge is swallow
  • Head that is small
  • Short palpebral fissures
  • Tip of nose broad
  • Flat nasal bridge
  • Lateral telecanthus
  • Drooping upper eyelid
  • Eyes are wide-set
  • Blepharophimosis
  • Prominent ears
  • Epicanthal folds
  • Dysplastic ears that is mild
  • Lower jaw small
  • Facial skin eczema
  • Sparse scalp hair
  • Flexural areas eczema
  • Delayed teeth eruption
  • Dental caries
  • Syndactyly of second toes
  • Brachyclinodactyly of fifth fingers
  • Hair is sparse on lateral eyebrows
  • Syndactyly of third toes
  • Eye abnormalities
  • Undescended testes
  • Tapetoretinal degeneration
  • Strabismus
  • Farsightedness
  • Small eye
  • Megalocornea
  • Abnormalities of the ocular fundus
  • Coloboma
  • Hypoplasia of iris
  • Abnormal ocular fundus veins
  • Ocular albinism

In spite of the head size being small of children with this syndrome, delayed development is not always observed in every case. The estimate of incidences of delayed development in these cases range from 30% to 70% with the majority of cases having mental retardation that is quite mild.

Numerous behavioral features have been defined by parents of these children as well as in the medical literature. These can include:

  • Hyperactivity that is extreme
  • Temper tantrums with problems self-calming
  • Predilection for concrete thinking rather than thinking in the abstract
  • Difficulties with language
  • Shyness with crowd aversion
  • Affection for rhythm and music

This syndrome is often linked to a deficiency in growth hormone.

Causes

This syndrome is passed on thru an autosomal recessive pattern of inheritance. Autosomal means that this disorder is not found on a sex chromosome, while recessive indicates that both parents must have the gene mutation for their child to have this syndrome. Parents who have one (1) child who is affected with this syndrome have odds of 25% that their next baby will have the disease.

The precise gene mutation that is accountable for this syndrome has not been identified. One (1) of the symptoms of Dubowitz syndrome consists of the displacement of chromosomes.

Cases of this syndrome have been seen from multiple different regions of the world with the greatest number occurring in the United States, Russia and Germany. There does not seem to be any ethnic pattern to the incidences of this syndrome. Dubowitz appears to be in males and females equally.

Treatment

There are numerous chronic medical problems linked with Dubowitz syndrome. They include:

  • Skin itching and inflammation – eczema
  • Vulnerability to viral infections
  • Allergies
  • Chronic constipation or diarrhea
  • Difficulties feeding and vomiting

These are conditions that should be individually managed with treatments that are appropriate. For instance, creams for the skin containing corticosteroid medication are used in treating eczema.

Other problems physically due to Dubowitz syndrome, for instance cardiovascular defects, or drooping eyelids – ptosis may be corrected surgically.

Diagnosis

Because the genetic reason is not known, there is no precise medical test that will conclusively consign the diagnosis of Dubowitz syndrome. This diagnosis is normally based on the appearance of facial characteristics of the individual who is affected as well as other aspects for instance data on growth and medical history. The diagnosis can easily be missed when the physician is unfamiliar with pediatric genetic conditions. Usually a pediatric geneticist will play an important role in having an accurate diagnosis especially when the syndrome is very mild or the symptoms are a little different in some way from other cases of this syndrome.

Prognosis

Concerning the prognosis for individuals with this syndrome it is very good providing that the managing of medical situations is continued. Dubowitz syndrome has not been informed to cause any shortened of a person’s lifespan or any deteriorating conditions. Individual with this syndrome may anticipate living to adulthood and leading a fairly ordinary lifestyle, even when the majority will have some level of mental retardation.

Life Expectancy

The prognosis for an overall normal life span is good.

Lambert-Eaton Myasthenic Syndrome

Sep 18 2011 Published by admin under Uncategorized

What is Lambert-Eaton Myasthenic Syndrome?

This is a disorder also referred as LEMS. It involves the faulty communications between nerves and muscles which leads to weakness of the muscles. This syndrome is a very rare “autoimmune disorder”.

Individuals who develop LEMS are normally over 40 years of age, although it can develop at any age. This diagnosis is normally defined with blood tests and electromyography which also distinguishes it from myasthenia gravis which is a closely related autoimmune neuromuscular disease.

If the disorder is linked with cancer, the treatment of the cancer symptoms will often get rid of the symptoms of LEMS. Additional treatments can include azathioprine, steroids, and circulatory immunoglobulin that subdues the immune system and pyridostigmine and 3, 4-diaminophyridine, which enhances the neuromuscular communication. Sometimes, plasma interchange is needed to eradicate the antibodies.

LEMS is estimated to affect four (4) to ten (10) cases per million individuals, or approximately 2000 to 4000 patients in Europe and 1200 to 3100 patients in the United States and is considered a rare condition.

Symptoms

The symptoms and signs of this syndrome consist of:

  • Weakness in arms and legs
  • Physical exercise and high temperatures may worsen symptoms
  • Problems climbing stairs and rising from sitting position
  • Some individual may have vision that is double
  • Weakness of bulbar muscles that supply the throat and mouth
  • Eyelids drooping
  • Problems swallowing but usually only together with weakness of the leg
  • Weakness of respiratory muscles may occur in advanced stages of the disease
  • Problems with coordination – ataxia
  • Dry mouth
  • Disruption of the autonomic nervous system
  • Constipation
  • Impaired sweating
  • Blurred vision
  • Orthostatic hypotension –blood pressure falls on standing, possibly leading to blackouts
  • Impaired sweating
  • Metallic taste in the mouth

On neurological exam, weakness is established with the normal testing of power but is often less severe than expected on the basis of the symptoms. Strength will further improve with repeated tests example power improves on repeated hand grip. This is a sensation denoted to as “Lambert’s sign”. At rest, reflexes are normally reduced; with use of muscle, reflex strength is increased – a LEMS distinctive sign. The “pupillary light reflex” can be sluggish.

When LEMS is linked with cancer of the lung, there might not be any indicative signs of cancer at the time, such as coughing blood, cough, and loss of weight. It has been described that LEMS linked with lung cancer is additionally severe.

Causes

LEMS happens when the cells of the nerves do not release enough of the chemical referred to as acetylcholine. This is the chemical sends impulses between the nerves and the muscles.

This causes weakness of the muscle as well as other symptoms that are similar to myasthenia gravis. But, as muscle continues to contract or tense up, acetylcholine may accumulate in larger amounts for the strength to slightly improve. Rather than getting weaker as it continues to contract frequently, it will become stronger for a short time.

LEMS can also be linked with autoimmune diseases, such as hypothyroidism or diabetes Type 1. Myasthenia gravis also might occur in the company of tumors. Individuals with MG with no tumor and individuals with LEMS with no tumor have comparable genetic deviations that seem to incline them to these diseases.

Treatment

There is currently no cure existing for LEMS. The treatment that is most effective when cancer is present is extermination of the cancer though other drugs have been used with some success. Management thru medication is concentrated at dismissing the symptoms. Drugs may be used to discharge more of the neurotransmitter that these muscles are not receiving enough of. There are other drugs that may be taken that also slow down the production of the antibodies that are created. These antibodies are what at the beginning cause the muscles to cease contracting. Another option of treatment is plasmapheresis. With this procedure, the blood plasma is removed and replaced.

Treatment of LEMS with azathioprine, corticosteroids and 3, 4-diaminopyridine has not yet gained much success regarding completely curing this condition. Plasma exchange or intravenous immunoglobulin may be tried and have some success in aiding treatment of this medical condition.

Diagnosis

LEMS is a syndrome of neuromuscular junction communication with the main demonstration of muscles that are weak. Information of elusive clinical features as well as lab anomalies that go together with LEMS allows for the early identification of the disorder. Early identification is especially significant because of its strong link with small cell lung cancer. LEMS can transpire at any point in the course of cancer, but the earlier it is found it serves as a marker for early disease.

Prognosis

The prognosis depends mainly on the nature and presence of any underlying cancer or the severity of any other associated autoimmune disease.

LEMS often leads to timely discovery of SCCL so individuals with LEMS and SCCL often have an improved prognosis. If LEMS has been indicative for two (2) years as well as having no underlying cancer, the LEMS is most likely of autoimmune cause. Prognosis is at that time established on how severe the dysfunction is, as well as the severity and existence of other autoimmune situations.

Extreme severity is typically recognized within months of the development of the first symptoms. Relapse, attack or flare-up can occur as secondary to undercurrent illness as well as medications that affect neuromuscular transmission. Most patients find that therapy can aid to get rid of symptoms partially; however, the usual symptoms advance over time.

Intersection Syndrome

Sep 16 2011 Published by admin under Uncategorized

What is Intersection Syndrome?

This is a condition of the wrist and forearm that is painful. It may disturb individuals who do wrist actions repeatedly, for instance downhill skiers, weight lifters, and any other sports that have repetitive motion. Shoveling and heavy raking may also trigger this syndrome.

Intersection Syndrome Symptoms

The friction on the tendons of the wrist with this syndrome causes swelling and pain in the tenosynovium which covered the tendons. This friction hinders the normally smooth sliding action. The individual might even be able to hear a squeaking noise as well as feel scraping as these tendons rub up against the muscles. This is referred to as crepitus. Individuals can have redness and swelling at the intersection point. Pain may migrate down to the thumb or upwards along the brink of the forearm.

Intersection Syndrome Causes

This condition is caused by the overuse of the wrist extensor tendons the tenosynovial lining which is slippery can develop inflammation from the continued rubbing against the two muscles of the thumb. As the tenosynovium becomes more inflamed and more irritated, it swells and then causes thickening. Pain will then be felt when the wrist is moved due to the swelling tendons rubbing against the muscles of the thumb.

Wrist extensor tendons execute like a bow that a violin player would use and the muscles of the thumb are like the violin strings. The wrist curls down and in with the tendons rubbing back and forth in contact against the muscles of the thumb. The friction continues to build up, much the same as the effect created by two sticks rubbing together. All of this leads to inflammation and irritation of the tenosynovium which covers the wrist extensor tendons.

These wrist extensor tendons become stressed by any actions creating the wrist to curl down and in, in the direction of the thumb. These movements of the wrist are particularly common in skiers who ski downhill as they plant the ski poles deep into the powdered snow. This same movement happens when pulling a rake against the ground. Some sports that may also stress the wrist extensor tendons include weight lifting, racket sports, rowing as well as canoeing.

Intersection Syndrome Treatment

Physicians normally can make the diagnosis of intersection syndrome while doing a physical exam. The majority of the time no distinctive tests are needed.

It is important to change or stop any activities that are causing these symptoms. Frequent breaks are needed when doing hand and thumb movements repeatedly. It is advised to avoid repetitive motions of the hand such as wringing, heavy grasping or twisting and turning movements of the wrist. Downhill skiers might get some relief by avoiding any heavy dragging and planting of the ski poles and by perhaps trying a shorter pole with a smaller basket diameter.

Keep the wrist in an alignment that is neutral. This means keep it in a straight line with the arm, with no bending down and in. Often the individual may be given a special thumb and forearm splint referred to as a “thumb-spica splint”. This keeps the lower thumb joints and the wrist from moving. By occasionally resting the wrist extensor tendons and the muscles of the thumb, it will allow this area to start the process of healing.

Drugs known as anti-inflammatory can help in managing the inflammation of the tenosynovium and relieving the symptom of pain. These medications can include OTC (over- the-counter) drugs such as aspirin as well as ibuprofen. Treatment with ice can also aid in decreasing swelling and relieve pain.

If the measures do not control the symptoms, the physician can suggest a cortisone injection. Cortisone is commonly used as an anti-inflammatory medication when early measures are not working. Injections of cortisone will normally control any inflammation especially during early stages of this syndrome. But, cortisone’s properties are only short-term, lasting from several weeks to several months.

The physician might also have the individual work with an occupational or physical therapist. The major focus of therapy is to eliminate or reduce the reason for the irritation to the thumb tendons. The therapist might check the workstation and see the way the individual does his/her work tasks. The therapist might also give suggestions about a healthy body alignment as well as wrist position, good exercises and tips on how to stop any future problems.

Surgery

Rarely needed but sometimes necessary is surgery to treat Intersection syndrome. This is used only in those cases that are extremely difficult. The surgeon can remove some of the tenosynovium which has thickened around the tendons. This surgery is referred to as “tendon release”.

This procedure is usually done on an outpatient basis meaning that the individual does not have to spend time in the hospital. It is normally done under general anesthetic that puts the individual to sleep, or an anesthetic for a certain region of the body that blocks the nerves in that area of the body. Injections of drugs such as lidocaine are able to block nerves for several hours.

The individual might also get an axillary block that numbs the arm or a wrist block which only numbs the hand. It is even conceivable to do this surgery by only using an injection of lidocaine around the region where the incision will be made.

The 1st step is to make a very small incision over the area where the two (2) muscles cross over the two (2) tendons of the wrist.

The surgeon will then identify the tendons that are irritated and then separate and remove the tenosynovium that is inflamed from the tendons.

The incision is then stitched up and the hand is bound with a dressing.

A period of rehabilitation is needed after surgery. Symptoms and pain usually begin to recover immediately but there might be sensitivity in the area around the incision for some months.

The individual will possibly need to have sessions with an occupational or physical therapist for six (6) to eight (8) weeks. Full recovery usually takes several months.
