[Quantitative evaluation of the dynamics of tubercular mediastinal adenopathy treated with rifampicin and ethambutol].

The authors have followed for one year the rhythm of involution of adenopathy in 114 patients aged between 0 and 16 years, with patent primary infection, in which four therapeutic regimens have been randomly applied, in continuous or intermittent administration, with INH-RMP; RMP-EMB; INH-EMB; INH-SM. Quantified data were obtained with the aid of a planimeter, measuring the surface of the adenopathy on trimestrial seriotomographies. The rhythm of involution was evaluated by the variable halving time of the surface of the adenopathy under treatment. The percentage, the data of the physical model, showed that in the first 3--4 months, detection of the curves is more rapid for RMP and the 7/7 formula, but with almost similar results (8--14%) at 12 months. By processing the data in the computer, depending on the mathematical model, it was estimated that the halving time is by 90,4 days shorter for RMP and similar for EMB and SM.

Why some patients prefer to become manic-depressive rather than schizophrenic.

This paper reports the authors' observations on fifteen families in which a young adult member had been diagnosed as manic-depressive. All families were seen in systemic family therapy, with intervals of four to six weeks between sessions. The circular questioning method developed by Selvini-Palazzoli [1] and her team was widely employed. All families could be described as extremely rigid and bound-up systems characterized by a "restrictive parental complementarity," typical dynamics of reciprocal delegation, and certain cognitive features and shared assumptions. These "manic-depressive" families show similarities as well as differences when compared with families with schizophrenic members (i.e., "schizo-present" families). Finally, some therapeutic implications of this view and approach are developed.

[Reactivity differences between serums of patients infected with HIV-2 and HIV-1 antigens according to the patients' geographic origin].

We tested 98 sera from HIV-2-infected patients for cross-reactivity with HIV-1 antigens in a competitive EIA test and western blotting. The sera were obtained during epidemiological surveys in Cape Verde Islands (n = 47) and Mali (n = 51). There were significantly more cross reactions with sera from Mali. Similar results were obtained with sera from African patients resident in France. Samples from HIV-2-infected patients from Burkina Faso, Ghana, Ivory Coast and Mali were more often reactive with HIV-1 antigens than were those from HIV-2-infected patients from the western Atlantic coast (Cape Verde, Guinea Bissau and Senegal). These data underline the importance of using specific tests for HIV-2 sero-positivity, and the need to include a panel of HIV-2-positive sera of different geographic origins in quality control kits.

[Perianal cutaneous ulcerations in the tropical zone. Proposal for a diagnostic and therapeutic decision tree. A case report].

Perianal cutaneous ulcerations in tropical countries have multiple causes: bacterial, viral and parasitic. Taking the opportunity of a case observed in Bambari (CRA) of which the etiologic origin was not clearly established, the authors offer a proposal for a diagnostic and therapeutic protocol aimed at easing decision. Etiologies quickly cured, such as amoebiasis and tuberculosis have to be explored in priority.

[The isolation and subtyping of the human immunodeficiency virus (HIV) from children in Moldova. The evidence for subtype F].

HIV epidemic related to nosocomial transmission in Romanian nursed children represents up to now more than 50% of paediatric AIDS cases in Europe. Although the sources of this epidemic are obscure, HIV-1 subtype F, a minor form in Brasil and Africa, realised a founder effect in this risk group, thus becoming the major form in Romanian epidemic. This study presents the results of the virus isolation from HIV-infected children in Northeast Romania. Heteroduplex mobility assay (HMA) was performed in order to establish HIV-1 viral subtype for 6 isolates. All tested HIV-1 strains were proved to belong to F subtype. So, our study confirm that HIV-1 subtype F is responsible for the epidemic in the risk group of Romanian nosocomially infected children.
