ABSTRACT
Desmoplastic infantile tumors are rare supratentorial brain tumors that occur in pediatric patients. Desmoplastic infantile tumors are made up of 2 subtypes: desmoplastic infantile gangliogliomas and desmoplastic infantile astrocytomas. Desmoplastic infantile tumors are often identifiable on imaging on the basis of multiple characteristics. Nevertheless, pathologic analysis is required to confirm the diagnosis, particularly when the imaging features are atypical. Here, the radiology findings, surgical approach and subsequent management, and pathology of a desmoplastic infantile ganglioglioma are described.

PIP: Sponsored by the US Department of State and the US Army Pacific as part of a Medical Readiness Training Exercise, 17 physicians from Tripler Army Medical Center traveled to Outer Mongolia during September 1995 to examine the practice of medicine in the country. The obstetrical care observed was delivered at Third Women's Hospital in Ulanbataar. Prenatal care in Mongolia is provided mainly by family physicians, with the family doctor visiting each pregnant patient every month for the first 5 months, increasing to weekly visits at 7 months. The patient is taken to an obstetrical or women's and children's hospital when she reaches term or goes into labor. The staff at Third Women's Hospital deliver approximately 2000 babies annually and perform approximately 1000 pregnancy terminations through sharp curettage. The cesarean section rate is reported to be 10%. The hospital has no laboratory or X-ray capability, but can send out for such tests on rare occasions. During labor, patients are fully ambulatory on an as-needed basis. Fetal monitoring is not routinely available, except for occasional auscultation, patients in labor were not given IV fluid, delivery rooms were bleak and with only antiquated equipment, lighting was poor, and gloves were reused until they were too tattered for reuse. The authors discuss their experience with 3 cesarean sections and 1 ectopic pregnancy performed while in the country.^ieng

Pyridostigmine was first used extensively during Operation Desert Storm for prophylaxis against the effects of nerve agents. After initial reports of asthma exacerbations following its use, we gave 10 asthmatic and 6 non-asthmatic soldiers a 30-mg dose of pyridostigmine. We found no changes in forced vital capacity in any of the soldiers, but observed exacerbation of asthma symptoms in seven of the asthmatics. Severity of the exacerbation correlated best with severity of asthma in the desert and inversely with body weight. The irritant effect of the dust may predispose asthmatics to worsen after pyridostigmine, an effect not seen in the laboratory.

This paper outlines part of a course evaluation which involves two objective tests based on prestated behavioural objectives. The mid-year test gave cause for satisfaction but the end-of-year examination showed a gross decline. An analysis of cognitive levels was done using Bloom's taxonomy as a basis, and it became apparent that in the end-of-year examination students were required to function at considerably higher cognitive levels. Care must obviously be taken in ensuring that examination papers accurately reflect both the skills and the cognitive levels which students are expected to attain.
