Blood zinc status and zinc treatment in human immunodeficiency virus-infected patients.

We investigated the zinc concentration in blood and the effect of zinc supplementation in 11 male outpatients seropositive for human immunodeficiency virus at stage 5 according to the Walter Reed classification. Zinc concentration was measured in serum, platelets, mononuclear and polymorphonuclear cells, and erythrocytes. There was a significant increase in serum zinc concentration after zinc administration, but the zinc level in blood cells remained unchanged. All patients showed a progressive gain in body weight and a slight elevation in levels of CD4+ cells. No adverse side-effects were noticed.

HIV infection acquired by a nurse.

We report here the history of the first case of occupationally acquired HIV infection in Italy. Results of serological investigations sequentially performed allow the investigators to outline the natural history of the infection in this case.

Acquired Immunodeficiency Syndrome

The Karpas AIDS Cell Test compared with an enzyme-linked immunosorbent assay for detecting antibody to the human immunodeficiency viruses (HIV-I and HIV-2).

We have compared the Karpas AIDS Cell Test for antibodies to the human immunodeficiency viruses (HIV) with a commercial enzyme-linked immunosorbent assay (ELISA) (Organon Teknika) by testing serum samples from 324 intravenous drug abusers in Turin. The cell test was found to be more sensitive and as specific as the ELISA with the serum samples from the drug abusers. In Lisbon, 30 samples were tested on slides containing cells infected with HIV-1 and/or HIV-2. All 15 samples, which were positive for HIV-2 alone (in the HIV-2 Elavia test and by the Western blotting technique), were also positive in the Karpas AIDS test. In contrast, only one of the 15 samples (7%) gave a positive reading in the ELISA for HIV-1. Results of 30 samples tested in Turin and Lisbon by the Western blotting technique agreed closely with those obtained with the Karpas AIDS Cell Test. We were also able to show that the entire test can be performed at room temperature and completed within 1 hour. Moreover, the cell test requires minimal skill and simple equipment and is inexpensive. It also includes non-infected cells as a control and the specificity of positive samples may be verified with a bench microscope. Furthermore, this test which detects antibodies to both HIV-1 and HIV-2 allows rapid typing of the infecting strain.

Sources of fungal contamination in a burn-care unit.

A microbiological study was carried out in the burn-care unit of the Centro Traumatologico Ortopedico of Turin (Italy) in order to detect the most important sources of fungal contamination in patients at high risk of infection. Identification of the fungi was carried out only for those of medical mycological interest, with the exclusion of the yeast isolates.

[Hepatic laparoscopy and biopsy in the diagnosis of hepatic cirrhosis].

316 cases of proved hepatic cirrhosis (HC) which underwent Laparoscopy (L) were analysed. In 94 cases, hepatic biopsy by needle (HBN) was also practised under laparoscopic view, 96 cases were controlled until death, with a follow-up of almost 90 months. In 54 of these, there is a complete necropsy study. The performance in diagnosis of cirrhosis, L and HBN are compared separately. L gave the exact result of 96.6% and HBN 74.7%. HBN commonly practised with a Menghini needle (1.2 or 1.4 mm) as it is one that produces less complications, gives and insufficient sample, which determines that in 25.3% of the cases under biopsy, the HC diagnosis could not be proved, while L only fails in this aspect, in 3.38%. To this disadvantage of HBN, we must add another negative factor, the frequency which HBN can not be practised due to prothrombin under 50%, which nevertheless is not an obstacle for practising an L. In this series we have not reported any deaths with this two techniques. L has the additional advantage to contribute other useful data which can not be obtained with HBN alone. as revealing signs of portal hypertension, and hepatobiliary or peritoneal pathology which can coexist with HC. Due to this reasons, in the study of HC, we preferred as the first method of diagnosis, L, instead of HBN. When through this endoscopy we obtain the typical aspect, we omit adding HBN, which we only practised in doubtful cases of not very nodular livers (glabra cirrhosis) or when a probable post-hepatis, Wilson disease or hemochromatosis is being investigated. In the present conditions, we believe that the new methods of diagnosis "of non invasive images" can not substitute L or HBN in precising the diagnosis of HC.
