Apraxia: Symptoms, Causes, Tests,Treatments

What Is Apraxia?

Apraxia is a poorly understood neurological condition. People who have it find it difficult or impossible to make certain motor movements, even though their muscles are normal. Milder forms of apraxia are known as dyspraxia.

Appendicitis is an inflammation of the appendix, a 3 1/2-inch-long tube of tissue that extends from the large intestine. No one is absolutely certain what the function of the appendix is. One thing we do know: We can live without it, without apparent consequences.

Anthrax

Anthrax is an acute disease caused by the bacterium Bacillus anthracis. Most forms of the disease are lethal, and it affects mostly animals. It is contagious and can be transmitted through contact or consumption of infected meat. Effective vaccines against anthrax are available, and some forms of the disease respond well to antibiotic treatment.

Anotia

Anotia ("no ear") describes a rare, congenital deformity, that involves the complete absence of the pinna, the outer projected portion of the ear, and narrowing or absence of the ear canal. This contrasts with microtia, in which a small part of the pinna is present. Anotia and microtia may occur unilaterally (only one ear affected) or bilaterally (both ears affected). This deformity results in conductive hearing loss, deafness.

Angina (Chest Pain)

What Is Angina?

If you have a feeling of pressure or a squeezing in your chest, it may beangina. It can feel like a heart attack, but often it's a warning sign from your heart.

There's a lot you can do to stop it from happening. Usually, medicine along with lifestyle changes can control angina. If it's more severe, you may need surgery, too. Or you may need a stent, a tiny tube that props open arteries.

Anemia

Understanding Anemia 

What Is Anemia?

Anemia is a condition that develops when your blood lacks enough healthy red blood cells orhemoglobin. Hemoglobin is a main part of red blood cells and binds oxygen. If you have too few or abnormal red blood cells, or your hemoglobin is abnormal or low, the cells in your body will not get enough oxygen. Symptoms of anemia -- 

like fatigue -- occur because organs aren't getting what they need to function properly.

Abscess

Abscess Overview

An abscess is a tender mass generally surrounded by a colored area from pink to deep red. Abscesses are often easy to feel by touching. The middle of an abscess is full of pus and debris.

Painful and warm to touch, abscesses can show up any place on your body. The most common sites are in your armpits (axillae), areas around your anus and vagina (Bartholin gland abscess), the base of your spine (pilonidal abscess), around a tooth (dental abscess), and in your groin. Inflammation around a hair follicle can also lead to the formation of an abscess, which is called a boil (furuncle).

Unlike other infections, antibiotics alone will not usually cure an abscess. In general an abscess must open and drain in order for it to improve. Sometimes draining occurs on its own, but generally it must be opened by a doctor in a procedure called incision and drainage (I&D).
