Fifty-two medical student suicides.

The authors surveyed all U.S. medical schools to ascertain the frequency with which medical students attempt suicide, complete suicide, and seek psychiatric treatment. In the classes of 1974-1981 the annual suicide rate for male students was 15.6 per 100,000, which is comparable to their agemates in the national population. The rate for female students equaled that of the male students but was three to four times that of their agemates. Seventy-six percent of the suicides were committed by sophomore and junior students, and 50% were committed in November, December, or January. The authors discuss four steps schools can take in suicidal prevention.

Bone mass in lifetime tennis athletes.

The effects of physical exercise on the status of bone mineralization for a population of lifetime athletes were investigated. The bone mineral content of the radii of experienced male tennis players was measured. The bone mass of the radius of the playing arm (mean, 1.37 g/cm) was greater than that of the nonplaying arm (mean, 1.23 g/cm) in all but one person. The results were compared with data for a nonathletic (normal) population. The quantity of bone mineral present in the playing arms of the athletic population was greater than that of the dominant arms of nonathletes, which suggests that playing tennis during a lifetime may produce a localized increase in bone mineralization that is greater than that found in nonathletes.

Absence of imune deficiencies in a case of progressive multifocal leukoencephalopathy.

Progressive multifocal leukoencephalopathy (PML) is a rare disease related to a slow virus infection of the central nervous system; it is usually seen in patients who have impaired immunologic function. The present patient with biopsy-proved PML was found to have no demonstrable defects in either cellular or humoral immunity as assessed by multiple parameters. Thus, it appears that PML may occur in the presence of intact immune responses.

DiC-like syndrome after envenomation by the snake, Crotalus horridus horridus.

After envenomation by the timber rattlesnake (Crotalus horridus horridus) a young man showed massive swelling and ecchymoses of the involved extremity, generalized petechiae and a large hematoma of the left upper eyelid. Two weeks later he was completely well. The first blood sample was incoagulable and showed high titers of fibrin split products by the MISFI and staphylococcal clumping tests. Immounoelectrophoresis showed both D and E fragments, but only D was present at 18 hours. The profound thrombocytopenia and hypofibrinogenemia gradually improved, and split products disappeared. In vitro the venom had thrombin-like activity, clotting fibrinogen or plasma and aggregating platelets. These activities could be inhibited by antivenom but not by heparin. There was no evidence that thrombin formation was actually involved: hence, the syndrome is called DIC-like.
