Anorexia nervosa. Hospitalization on adolescent medicine units and third-party payments.

To determine the appropriateness of hospitalization for patients with anorexia nervosa on an adolescent medicine unit, major and minor criteria justifying admission were developed. Hospitalization was considered necessary when one major and three minor, or six minor, criteria were met. A retrospective review of 20 patient records was conducted and all met the criteria. Eighteen patients were discharged with objective findings of improvement. Two were transferred to a psychiatric unit for prolonged care. A review of the financial records disclosed that four hospitalizations had been contested (partially or in total) by the patients' insurance company. Thus, in 20% of the records meeting the criteria for admission third parties refused to pay. Because insurance company denial may seriously undermine therapy and adversely influence outcome, it is proposed that a category of "Malnutrition Secondary to Anorexia Nervosa" be accepted as reimbursable under medical coverage for acute care treatment in qualified adolescent medicine units.

Eosinophilia in Southeast Asian refugees: evaluation at a referral center.

We determined the cause of persistent eosinophilia in 128 Indochinese refugees for whom initial comprehensive routine screening had failed to yield an explanation. Intestinal parasitism with one or multiple organisms was the cause of eosinophilia in all but six of these patients. Hookworm and Strongyloides stercoralis were among the potentially pathogenic organisms most frequently implicated (55% and 38%, respectively). There was no correlation between the age or sex of the patients and the type of infecting organism. We also confirmed the usefulness of a previously described serological test for diagnosing infection with Strongyloides stercoralis and examined the test's ability to distinguish between infected and noninfected individuals and to determine parasitological cure.

Carrier cultures of simian foamy virus.

The production of cultures of HEp-2 and BHK-21 cells persistently infected with a type 1 simian foamy virus is described. After infection, HEp-2 cells showed no structural changes, whereas BHK-21 cells lost their normal spindle shape and showed mitochondrial damage, and some cells contained many lysosomes. Thin sections also showed that a few BHK-21 cells contained virus particles in low concentration, and infectious virus could be isolated from both the cells and the supernatant fluid. No virus was seen in thin sections of HEp-2 cells, although infectious virus in low titer could be recovered intermittently from lysed cells. Both carrier cultures were immune to challenge with homologous virus and antigen could be detected in over 90% of the cells even after growth for 9 weeks in the presence of virus-neutralizing serum. The distribution of antigen in carrier cultures of both cell types is described and compared with that seen in cytocidal infections.

New bacteriophage of Haemophilus influenzae.

Some properties of a newly isolated Haemophilus influenzae bacteriophage are described. The phage is morphologically distinct from previously described H. influenzae phages.
