Male hair loss often responds to minoxidil and finasteride . As male pattern baldness occurs, hairs in the affected area become shorter and finer and are less pigmented with successive growth cycles. This type of baldness is also known as androgenic alopecia and is associated with the presence of dihydroxytesterone, which is a metabolite of testosterone. Finasteride is a competitive inhibitor of type II 5alpha-reductase that can lower dihydroxytesterone levels, preventing baldness.

The pathologic causes of alopecia are often evaluated when treating baldness in men. The patient’s medical history plays an important role in diagnosing the condition. The key elements considered include family history, medications, underlying medical illness, stress factors and the patterns and speed of hair loss. Male pattern baldness is characterized by an M pattern, while patchy alopecia is usually associated with conditions such as tinea capitits, lupus erythematosus and immune-mediated alopecia areata. Telogen effluvium is alopecia that occurs after a stressful event.

As of now, there are no studies that compare the effectiveness of minoxidil and finasteride. Some medical researchers have claimed, though, that minoxidil at two percent topical solution could grow hair in about 50 percent of patients. The medicine appeared to be ineffective for frontal baldness and effective in preventing hair thinning and loss. Studies on the effectiveness of finasteride on the other hand revealed that its greatest benefit may be in preventing further hair loss in men at the early stages of baldness.

Both minoxidil and finasteride have proven to be well tolerated by patients. The reported side effect of minoxidil is pruritis of the scalp, while finasteride revealed sexual side effects such as decreased libido and erectile dysfuction. Finasteride is not recommended to be used in women and children. When counseling patients, physicians should stress that effectiveness have been primarily demonstrated in younger men.

Scientists agree that further study is required to determine the long-term benefit of medications for male hair loss. It may also be possible to predict those who will respond to treatment with further study.

There are many ways video is already being incorporated in medical technology. For example, there are many benefits to the use of video capsule endoscopy. A tiny, swallowable device, which includes a light source, an optical lens, a battery, and a transmitter, is ingested. The resulting video sends clearer pictures and helps identify more ailments that were previously more difficult to detect. The procedure is easy to perform, with few complications, and patient approved videos can then be used for further study, research, and in educational materials. When surgical videos are incorporated in educational presentations, the experience can be much more informative and understandable by a variety of viewers. The viewer is better able to relate to the information being presented, and it’s easier for the viewer to retain images, animations, and graphs, than plain text. Physicians are also able to communicate with patients in a more direct manner, and patients have a face to associate with a name or procedure. There is no question video is being used more frequently in many research and educational pursuits, and the medical field is helping lead the way. So if you are a physician or medical professional looking to find new channels for distributing information, video is an enticing way to capture and express your procedures and materials. Also, patients can benefit from viewing and learning from these videos. So remember to include video as an essential part of the plan when bringing your profession to the cutting edge of technology.
