Aids

An acquired defect of cellular immunity associated with infection by the human immunodeficiency virus (HIV), a CD4-positive T-lymphocyte count under 200 cells/micro liters or less than 14% of total lymphocytes, and increased susceptibility to opportunistic infections and malignant neoplasm’s. Clinical manifestations also include emaciation (wasting) and dementia. These elements reflect criteria for AIDS as defined by the CDC in 1993.


(Aids) Acquired Immune Deficiency Syndrome
Acquired immune deficiency syndrome or acquired immunodeficiency syndrome (AIDS) is caused by an infection with the human immunodeficiency virus (HIV).
AIDS is now a pandemic. As of 2009, AVERT estimated that there are 33.3 million people worldwide living with HIV/AIDS, with approximately 2.6 million new HIV infections per year and 1.8 million annual deaths due to AIDS. In 2007, UNAIDS estimated: 33.2 million people worldwide had AIDS that year; AIDS killed 2.1 million people in the course of that year, including 330,000 children, and 76% of those deaths occurred in sub-Saharan Africa. According to UNAIDS 2009 report, worldwide some 60 million people have been infected, with some 25 million deaths, and 14 million orphaned children in southern Africa alone since the epidemic began
In excess of time, HIV infection destroys the helper T cells of the body's resistant system, resulting in a critical fall of the resistant system and the ability of the body to fight infection. Advanced HIV infection is called AIDS.
AIDS is frequently a sexually transmitted disease. HIV which causes AIDS is most often passed from one person another during sexual contact that involves vaginal, oral, or anal sex. HIV can also be passed to another person through other means, such as through contact with blood or body fluids. This can occur through such processes as blood transfusions or sharing needles contaminated with HIV.

Asthma


Asthma is the most common chronic disease among children. Asthma triggers include viral infections; environmental pollutants, such as tobacco smoke; aspirin, nonsteroidal anti-inflammatory drugs, and sustained exercise, particularly in cold environments.
I. Diagnosis
A. Symptoms of asthma may include episodic complaints of breathing difficulties, seasonal or nighttime cough, prolonged shortness of breath after a respiratory infection, or difficulty sustaining exercise. B. Wheezing does not always represent asthma. Wheezing may persist for weeks after an acute bronchitis episode. Patients with chronic obstructive pulmonary disease may have a reversible component superimposed on their fixed obstruction. Etiologic clues include a personal history of allergic disease, such as rhinitis or atopic dermatitis, and a family history of allergic disease.C. The frequency of daytime and nighttime symptoms, duration of exacerbations and asthma triggers should be assessed. D. Physical examination. Hyperventilation, use of accessory muscles of respiration, audible wheezing, and a prolonged expiratory phase are common. Increased nasal secretions or congestion, polyps, and eczema may be present.
