Leg cramps (systremma0 and "restless legs" syndrome. Response to vitamin E (tocopherol).

A clinical investigation into the therapeutic value of vitamin E (tocopherol) in certain dermatological conditions of obscure etiology led to the incidental observation that this compound produced beneficial effects in some of the patients who were suffering from frequent and severe nocturnal leg cramps. Nearly all of the patients with leg cramps received prompt and gratifying relief from their symptoms while taking vitamin E in the form of d, alpha-tocopheryl acetate, 100 I.U. three times a day before meals. The group included 24 private patients with leg cramps and two with the "restless legs" syndrome, probably a related condition. One of the patients with leg and foot cramps also had severe nocturnal rectal cramps which were also relieved. Nocturnal leg cramps constitute a relatively common complaint in the general practice of medicine and may be very distressing to the patient. Not only is the cause obscure and the treatment relatively unsatisfactory, but even its proper medical name, systremma (anything twisted up together), is unknown to most physicians.

Stretch garment dermatitis.

A disease of the skin, not hitherto described, is caused by pressure or tension on the skin from the wearing of tight-fitting stretch garments such as "stretch bras," "stretch girdles" and "stretch socks." The condition is not due to chemical sensitization of fabrics, dyes or other additives but is of mechanical origin. The eruption may assume various clinical forms and may be characterized by a nondescript erythematous and eczematous appearance or may consist of an exaggeration, in the areas covered by the stretch garment, of already existing dermatosis such as lichen planus, psoriasis, acne vulgaris, discoid lupus erythematosus or atopic dermatitis.

Hair transplantation for male pattern baldness: aesthetic considerations and current status.

The multiple punch technique of hair transplantation, utilizing the principle of donor dominance, has proven to be a cosmetically acceptable procedure in properly selected patients in the presenter's 24-year experience. Careful planning with attention to aesthetic principles, especially in frontal hairline placement, in donor site selection and with regard to the ratio between the donor supply and the existing or potential future extent of baldness, together with meticulous surgical technique, are essential for satisfactory results. Scalp reduction, in which bald areas of crown and midscalp are serially excised, with extensive subgaleal undermining is a highly useful adjunct to grafting in many patients with moderately extensive male pattern baldness who have adequate scalp mobility by enabling the available donor supply to be concentrated and thus provide more effective coverage in the frontal scalp.

A pilot epidemiologic study of possible health effects associated with 2,3,7,8-tetrachlorodibenzo-p-dioxin contaminations in Missouri.

In 1971, 2,3,7,8-tetrachlorodibenzodioxin (TCDD)-containing waste oils were sprayed for dust control on residential, recreational, and work areas in Missouri. In several of these areas, the magnitude and the extent of this environmental contamination were not known until late 1982 or 1983. In the first phase of the investigation, a group of persons considered to be at highest risk of exposure and an appropriate comparison group were selected from reviews of Health Effects Survey screening questionnaires. These persons received complete medical examinations and a series of laboratory tests focused on detecting presymptomatic effects in key target organ systems (i.e., hepatic, dermatologic, immunologic, and neurologic effects). Comparisons of these two groups did not produce any firm indications of increased disease prevalence directly related to the putative exposures; of significance is the fact that no cases of chloracne or porphyria cutanea tarda were seen. Nevertheless, no overall definitive conclusion should be based just on this initial pilot study. Insights were provided that are being examined in more refined epidemiologic studies using different designs and strategies--especially of larger, more homogeneous population groups in which exposure status can be better characterized--focused primarily on discerning any potential effects on the urinary tract, liver, neurological, and immune systems. Concurrently, research into the development of replicable laboratory analytical methods and reference ranges for measuring TCDD body burden are being pursued.

Use of the Threat Index with family members waiting during surgery.

We describe the use of the 40-item Threat Index (TI) with family members (N = 206) of surgical patients who also completed Templer's (1970) Death Anxiety Scale, the Death-of-Self and Dying-of-Self subscales of the Collett-Lester (1969) Fear of Death Scale, and the Death Acceptance subscale of Reker and Peacock's (1992) Life Attitude Profile-Revised. Word sets from the 40-item TI that are part of the 25- and 7-item versions of the TI produced strong alphas and correlations to their parent instrument. Regression analyses indicated that self/ideal-self scores and previous experience as a hospital patient were significantly associated with TI scores. We conclude that if the time available for completion and scoring of the TI is limited, the shorter versions can be used, although their alpha strengths are slightly lower than that of the full TI and the respondent's age influences the scores.
