We report the case of a 78-year-old-woman with a meningitis caused by Bacteroides fragilis revealing a malignant tumor. The epidemiologic, etiologic and therapeutic features of these meningitis are reviewed.
To examine Senegalese women to confirm and extend associations between HLA class II types and cervical cancer previously observed among African-American, Caucasian, Hispanic, and Japanese ethnic populations, 55 Senegalese women with invasive cervical carcinoma were compared with age-matched (human papillomavirus) HPV-positive (n = 83) and HPV-negative (n = 107) control women. PCR-based HPV and HLA typing methods were used. Data were analyzed using a global randomization test and conditional logistic regression. Although this study failed to confirm a previously reported association between cervical cancer and DQB1*03 alleles, the DRB1*1101-DQB1*0301 haplotype was detected more frequently among cervical carcinoma cases than among controls (adjusted odds ratio, 2.6; 95% confidence interval, 1.0-7.1). Furthermore, as reported by others, we observed a negative association of borderline statistical significance between DRB1*13 and cervical carcinoma (adjusted odds ratio, 0.5; 95% confidence interval, 0.2-1.1). Observations from this study confirm earlier findings of a negative association between DRB1*13 and cervical cancer and suggest that specific DRB1-DQB1 haplotype combinations, rather than individual DQB1*03 alleles, increase the risk for cervical cancer.
A case of therapeutic overdosage in a 58-year-old woman is reported. Lithium plasma level was 3.7 mmol.l. All clinical and biological disturbances regressed in 3 days after controlled rehydration only. Aetiology, clinical picture, biological characteristics and treatment according to the severity of the lithium poisoning are discussed.
