Blood lead levels of some children in New South Wales.

The venous blood lead levels of 400 children under 16 years of age who lived in Port Kembla or in Cocklecreek, and of 202 patients in several New South Wales hospitals are reported and compared with criteria announced by the National Health and Medical Research Council, the European Economic Community, and the American Environmental Protection Agency. The results of this study do not show reason for concern. The samples from hospital patients stress the importance of domestic exposure, such as to flaking paint containing lead. The findings of this study are also compared with a Victorian and a New South Wales survey of schoolchildren.

Smear platelet counts.

The average number of platelets per oil immersion field, in a count of ten oil fields, multiplied by 20,000 has proved to be a reliable estimation of platelets in normal and thrombocytopenic states. In the presence of thrombocytosis, ie, 25 or more platelets per oil immersion field, the smear count is less reliable. The multiplication factor of 20,000 was determined after statistical analysis of 288 consecutive unselected patients. Certain precautions should be observed, such as use of a fresh EDTA sample or freely flowing finger blood, a well made and well stained smear without platelet aggregates or precipitated stain particles, and an acceptable counting area on the film.

Hematology problem.

A hairy cell is a distinctive neoplastic cellular element with unique morphological and functional properties and is cytochemically identified by the tartrate-resistant acid phosphatase reaction. The identification of the hairy cell is essential for the diagnosis but a proper clinical presentation is also necessary. A careful scrutiny of a blood smear for the presence of hairy cells in, for example, a middle-aged male patient with pancytopenia and splenomegaly, is probably the most important step in diagnosis.

Tungiasis in Tennessee.

Tungiasis, an infestation by a burrowing flea, may cause multiple, painful lesions which, if they become secondarily infected, may eventuate in death. With increasing air travel to tropical areas, American physicians should recognize the lesion of this intracutaneous parasite. The fully developed lesion resembles an abscess with a black center. An infestation diagnosed in Memphis, Tennessee, is reported in a businessman who had returned from Brazil. Treatment consists of excision of the gravid female flea and careful cleaning of the cystic cavity. Healing is usually complete without sequelae. In an early infestation, the smaller gravid female, like a splinter, can be removed with a sterile needle. Tetanus prophylaxis may be indicated, depending on the wound and its location.
