Reye’s syndrome

30/05/2009

Reye’s syndrome is a disease characterized by:

  1. vomiting
  2. encephalopathy (disease of the brain)
  3. mental impairment
  4. personality changes
  5. deterioration of consciousness
  6. irritability, delirium and coma may accompany mental deterioration
  7. fatty degeneration of the liver

The disease usually presents after infection with varicella or influenza virus. Studies have demonstrated a strong epidemiologic association between the ingestion of aspirin during antecedent varicella or influenza-like illnesses and the subsequent development of Reye’s syndrome. The vast majority of cases present in children.

Diagnosis:

metabolic tests for:

  • hyperammonemia
  • elevated levels of alanine aminotransferase
  • aspartate aminotransferase

distinguishing test:

  • an electron micrograph
  • ultrastructural changes in liver tissue
  • specifically the proliferation of smooth endoplasmic reticulum and peroxisomes 
  • the presence of enlarged and pleomorphic mitochondria with loss of dense granules

Prognosis:

  • Reye’s syndrome is potentially fatal
  • The recovery of adults with the syndrome is generally complete, with liver and brain function returning to normal within two weeks of the illness
  • In children, mild to severe permanent brain damage is possible, especially in infants

Graves’ disease

29/05/2009

Graves’ disease is an autoimmune disease affecting the thyroid gland. The thyroid gland becomes enlarged. Hyperthyroidism symptoms are the result.

Symptoms

  • goiter
  • tachycardia (increased heart rate)
  • hypotonia (decreased muscle tone)
  • irritability
  • distrupted sleep pattern
  • irritability

 

Heredity:

  • relatedness factors in predispostion to the disease
  • an identical twin has a 25% chance of developing the disease if their twin is affected.

Treatment:

  • antithyroid medications such as carbimazole or methimazole and propylthiouracil may be used to decreased thyroid activity and control hyperthyroid symptoms
  • surgical removal of part of the thyroid gland may be performed to decreased thyroid activity

 


Blepharoptosis

28/05/2009

Blepharoptosis is a condition where the upper eyelid droops in an abnormally low position.

TREATMENT

Blepharoptosis repair is typically performed in an outpatient surgical setting. An anesthesiologist (MD) administers sedating medications while monitoring vital signs. The eyelid opening muscle is reattached or shortened through a small incision in the upper lid.

 Less commonly, the eyelid opening muscle is too weak to resolve the droopiness by the above technique. When this degree of muscle weakness is present, frontalis sling must be performed. This involves connecting the eyelid to the eyebrow (frontalis) muscle deep within the eyelid tissues.

Bullous pemphigoid (BP)

27/05/2009

Bullous pemphigoid, BP is a chronic autoimmune skin disease, involving the formation of subepidermal (below the skin) blisters . The body makes antibodies against the body’s type XVII collagen.Bullous_Pemphigoid

Manifestation:

  • Blisters appear as thin-walled sac filled with clear fluid.
  • skin is typically very itchy
  • large, red welts and hives may appear before or during the formation of blisters.
  • The blisters are widespread and usually appear on the areas of the body that flex or move (flexural areas).
  • About 15-20 percent of people with BP also develop blisters in the mouth or down the throat in the esophagus

Diagnosis:

  • via skin biopsy
  • tissue sample is taken and tested through autofluorescence for antibodies to collagen

 Treatments:

  • used to prevent infection
  • provide symptom relief
  • antibiotics such as tetracycline and minocycline are often used
  • the use of oral steroids such as prednisone and prednilosone may be to relive symptoms in severe cases
  • immunosupressants such as Immuran, Cellcept, Methotrexate, cyclophosphamide and Neoral may be used to manage symptoms.

RAI Assessment Tool

26/05/2009

The RAI or Resident Assessment Inventory tool is a standard patient assessment tool used in many countries around the world. This tool provides a common format for patient assessment, health and healing progress to increase ease of communication around patient care across the health care multi-disciplinary team.

Gastrectomy

22/05/2009

stomach

A surgical procedure to remove all or part of the stomach. The stomach is reattached at either end of the resection sites, or the intestine if the entire stomach or lower portion at the pyloric sphincter is removed. This is called an anastomosis. Anastomosis  is a surgical connection between two structures. It usually means a connection that is created between tubular structures, such as blood vessels or loops of intestine.

Applications:

  • to treat stomach cancer by removal of cancerous tissue
  • to treat perforations of the stomach wall
