    242 POST-GRADUATE MEDICAL JOURNAL August, 1938 Postgrad Med J: first published as 10.1136/pgmj.14.154.242 on 1 August 1938. Downloaded from SOME REMARKS ON DIFFERENTIAL DIAGNOSIS OF BLOOD DISEASES. By A. PINEY, M.D., M.R.C.P. (Assistant Physician, St. Mary's Hospital for Women and Children.) Differential diagnosis of blood diseases has been discussed time and again, but, as a rule, blood-pictures, rather than clinical features, have been taken into account, so that the impression has become widespread that the whole problem is one for the laboratory, rather than for the bed-side. It is obvious, however, that the first steps in diagnosis must be based on clinical signs and symptoms. In this paper, there- fore, certain outstanding clinical features of blood diseases, and various rather puzzling syndromes will be described. The outstanding external sign that leads the practitioner to consider the possi- bility of a blood disease is pallor, which is not quite so simple a state as is often supposed. It is, of course, well known that cutaneous pallor is not an infallible sign of anaemia, but it is often presumed that well-coloured mucous membranes are fairly good evidence that anaemia is not present. This is not necessarily true. The conjunctive may be bright pink in spite of anaemia, because mild inflammationProtected by copyright. may be present, masking the pallor. This is quite frequently due to irritation by eyelash dyes. Similarly, the finger-nails, which used to serve as a reliable index of pallor, are now found disguised with coloured varnish.

  • DERMATOLOGISTS SHARE SKIN CARE TIPS for PEOPLE with VITILIGO June Is Vitiligo Awareness Month
    DERMATOLOGISTS SHARE SKIN CARE TIPS FOR PEOPLE WITH VITILIGO June is Vitiligo Awareness Month ROSEMONT, Ill. (June 11, 2019) — Millions of people worldwide have vitiligo, a condition that causes the skin to lose its natural color, resulting in patches of light skin. Although the white or light patches do not typically cause other symptoms, the condition can cause low self-esteem and depression in patients—of whom nearly half develop vitiligo before the age of 21. Although there is no cure for vitiligo, dermatologists from the American Academy of Dermatology say there is a lot patients can do at home to make vitiligo less visible and help prevent the condition from spreading. “Many people with vitiligo do not have any other signs or symptoms and feel completely healthy,” says board-certified dermatologist Anisha Patel, MD, FAAD. “However, the change in appearance caused by vitiligo can affect people emotionally, especially those who are younger and more concerned about their appearance. The good news is that there are things patients can do at home to make the condition more manageable.” To help vitiligo patients care for their skin, Dr. Patel recommends the following tips: 1. Protect your skin from the sun. Exposure to the sun’s harmful ultraviolet (UV) rays increases your risk of skin cancer, including melanoma, the deadliest form. Since vitiligo skin can burn more easily, it’s important to protect your skin whenever you’re outdoors. To do this, seek shade, wear protective clothing—including a lightweight, long-sleeved shirt, pants, a wide-brimmed hat and sunglasses—and apply sunscreen to all areas of the body not covered by clothing.

  • What Is Albinism?
    INFORMATION ABOUT ALBINISM What Is Albinism? Albinism is an inherited genetic condition that reduces the amount of melanin pigment formed in the skin, hair and/ or eyes. Albinism occurs in all racial and ethnic groups throughout the world. In the U.S., approximately one in 18,000 to 20,000 people has some type of albinism. In other parts of the world, the occurrence can be as high as one in 3,000. Most children with albinism are born to parents whose hair and eye color are typical for their ethnic backgrounds. A common myth is that people with albinism have red eyes. Although lighting conditions can allow the blood vessels at the back of the eye to be seen, which can cause the eyes to look reddish or violet, most people with albinism have blue eyes, and some have hazel or brown eyes.
