Three-dimensional lithographic model building from volume data sets.
Computed tomographic images of a dry human skull and an in-situ knee joint were used to construct solid three-dimensional polymer models using stereolithographic techniques that have been introduced recently into the manufacturing industry. The stereolithographic technique makes use of a computer-steered narrow laser beam to solidify the model within a bath of liquid photocurable polymer. The method does not suffer from the cutting-tool size and path constraints encountered in the more commonly used process of machining the models from a solid block of foam.
An epidemiological and clinical study of snake-bites in childhood.
The last decade has seen major changes in the first-aid management of elapid snake-bites and the introduction of a new venom-detection kit which can identify the genus of medically-important snakes. In the light of these developments, we report a 10-year study that comprised 218 consecutive children who were admitted to hospital in southeast Queensland, after a confirmed or a suspected snake-bite. One-third (34.9%) of victims were preschool children (zero to five years of age) but the highest "at-risk" group comprised prepubescent boys. In 70% of cases, the bite was on a single lower limb. Of the 218 children who were admitted to hospital, 42% manifested local or systemic symptoms that were consistent with a confirmed snake-bite, irrespective of whether or not the species of snake was venomous. A positive identification of the genus of the offending snake was established in 18.8% of cases. In 35.8% of cases, the Commonwealth Serum Laboratories' Venom Detection Kit was used in an attempt to identify the involved snake, with 10 (4.6% of all cases) positive test-results. We have found that appropriate first aid was applied in the field in a maximum of 18% of cases. Antivenom was administered to 14 children, seven of whom received polyvalent antivenom; one child manifested a severe anaphylactic reaction. There were no fatalities in this series, and no permanent morbidity.

Munchausen's syndrome: an unusual case.
Unlike most Munchausen patients, Miss A. was willing to define herself as a psychiatric, as well as a medical-surgical patient. Consequently, it was possible to engage her in therapy in which observation could occur. It was found, also, that Miss A. had used eye drops to dilate her pupils to simulate a neurological disorder and had accidentally induced an anticholinergic delirium.
