[Determination of the sensitivity and specificity of an osteoporosis risk factor questionnaire].

OBJECTIVE: To determine de sensitivity and specificity of a questionnaire of osteoporosis risk factors. MATERIAL AND METHODS: In 1,088 files of postmenopausal women, osteoporosis risk factors such as age, time since menopause, former hormone replacement therapy (HRT) use, current use of HRT, former and current HRT use, fractures after 45 years age, actual weight, corticosteroid use and hyperthyroidism were analyzed, giving them different punctuation. Every punctuation was added in each patient. In all of them a dual emission X ray (DEXA) absorptiometry was done from lumbar column and hip (femoral neck, trochanter and Ward's triangle). Odds ratio, sensitivity, specificity, positive predictive value (PPV) and negative predictive value (NPV) were calculated for every one of the variables and DEXA T score as well as Spearman correlation coefficient. RESULTS: Odds ratio increased as the punctuation of the questionnaire increased. With four points in the questionnaire the PPV was 41%, the NPV 86%, the sensitivity 16% and the specificity 96%. A significant negative correlation was found between age, time since menopause, current use of HRT, former and current use of HRT and column and hip T scores, and with the punctuation for all the regions. A positive correlation was found between former fracture and column and femoral neck T scores, and with actual weight in all regions. CONCLUSIONS: This study showed that the questionnaire can be a useful instrument to identify patients at high risk of osteoporosis.

[Cancer of the lung in patients with HIV infection].

OBJECTIVE: To know the characteristics of lung cancer among patients with HIV-1 infection. METHOD: The clinical records of patients infected with HIV-1 and lung cancer diagnosed at our institution from January 1991 to April 1995 were reviewed. The epidemiological, clinical, histological and evolutive factors were studied. RESULTS: A total of 1,258 patients were diagnosed of HIV-1 infection during that period of time. Seven patients out of those 1,258 had also a lung cancer. Six were males. All of them were smokers and had severe immunodepression. In four cases the histological diagnosis was epidermoid carcinoma, in two adenocarcinoma, and in one case undifferentiated large cell carcinoma. Five patients were on advanced stages at diagnosis, and lung cancer was the direct cause of death. CONCLUSION: The frequency of lung cancer among our patients with HIV-1 infection was 5.5 per thousand, with predominance of epidermoid carcinoma.

[HIV and schizophrenia].

We report five cases of psychosis in patients with antibody to human immunodeficiency virus. All patients was man and intravenous drug abuser. The age range was 22 from 31 years with a mean of 25 years. In all cases acute schizophrenia was the first clinical picture of the HIV. Four patients had opportunistic infections and AIDS-Dementia Complex months later. If there is a genuine biological association between HIV carriage and schizophrenia illness, then HIV infection should be considered in the differential diagnosis of such an illness.
