Common acne, known medically as acne vulgaris, occurs most commonly in teenagers and to a lesser extent in young adults. The condition results in part from excessive stimulation of the skin by androgens (male hormones). Bacterial infection of the skin also appears to play a role.
What are the symptoms of acne?
Acne is a skin condition characterized by pimples, which may be closed (sometimes called pustules or “white heads”) or open (blackheads), on the face, neck, chest, back, and shoulders. Most acne is mild, although some people experience inflammation with larger cysts, which may result in scarring.

Acquired immunodeficiency syndrome (AIDS) is a condition in which the immune system becomes severely weakened and loses its ability to fight infections. Although some scientists, including a Nobel Prize-winning chemist, have questioned whether or not the human immunodeficiency virus (HIV) has actually been proven to cause AIDS. Most researchers do believe that HIV causes AIDS.
AIDS is an extremely complex disorder, and no cure is currently available. Certain drugs appear to be capable of slowing the progression of the disease. In addition, various nutritional factors may be helpful. However, because of the complicated nature of this disorder, medical supervision is strongly recommended with regard to dietary changes and nutritional supplements. People who have been infected with HIV are hereafter referred to as “HIV-positive.”

Prostatitis, or inflammation of the prostate gland, is a term that encompasses four disorders of the prostate: acute bacterial prostatitis, chronic bacterial prostatitis, chronic nonbacterial prostatitis, and prostadynia.
Chronic nonbacterial prostatitis (NBP), also called chronic abacterial prostatitis (CAP), is the most common form of prostatitis. NBP is usually caused by infectious agents such as fungi, mycoplasma, or viruses. Prostadynia (PD), also called chronic pelvic pain syndrome, is a noninfectious form of prostatitis. Although the cause is unknown, it has been proposed that PD may be a neuromuscular condition, causing pain of the pelvic floor muscles. Acute bacterial prostatitis (ABP) occurs from a urinary tract infection (usually from E. coli bacteria) that has spread to the prostate. Chronic bacterial prostatitis (CBP) is usually the result of a partial blockage of the male urinary tract, such as occurs with benign prostatic hyperplasia (BPH). Such blockages promote the harboring of bacteria from a previous infection and reduce circulation, thereby preventing both the body’s natural immune mechanisms and medication from getting to the site.

Attention deficit–hyperactivity disorder (ADD or ADHD) is defined as age-inappropriate impulsiveness, lack of concentration, and sometimes-excessive physical activity. ADHD has been associated with learning difficulties and lack of social skills. Obviously what constitutes “normal” in these areas covers a wide spectrum, and thus it is unclear which child suffers true ADHD and which child is just more rambunctious or rebellious than another. No objective criteria exist to accurately confirm the presence of ADHD. ADHD often goes undiagnosed if not caught at an early age, and it affects many adults who may not be aware of their condition.
What are the symptoms of ADHD?
ADHD is generally recognized by a pattern of inattention, distractibility, impulsivity, and hyperactivity estimated to affect 3 to 5% of school-aged children. Learning disabilities or emotional problems often accompany ADHD. Children with ADHD experience an inability to sit still and pay attention in class, and they often engage in disruptive behavior.
