We report 3 cases of Clostridium perfringens bacteremia with uterine gas gangrene. Clinical presentation included severe infectious syndrome, hemoglobinemia and hemoglobinuria, jaundice, uterine tenderness and hypertension. All 3 cases were first seen with installed renal failure. Diagnosis and modalities of therapy were reviewed. Clostridium perfringens bacteremia with uterine gas gangrene still occur in developing countries.

We report a case of symptomatic Klebsiella pneumoniae bacteremia following a jejunoscopy. Occurrence of bacteremia in patients undergoing gastro-intestinal endoscopy is reviewed.
Rearranged X chromosome in Turner syndrome (TS) are generally well tolerated but in cases of ring X chromosomes and of X/autosome translocations the incidence of mental retardation and other congenital abnormalities can be significantly higher. These abnormal phenotypes can be ascribed to failed or partial X inactivation. Here, we report a 10-year-old female who was referred for a cytogenetic analysis because she developed an alopecia universalis. The patient, of normal intelligence, had been found to have traits of TS, especially short stature. A first cytogenetic analysis showed a no mosaic 45,X karyotype. Since, the risk of developing gonadoblastoma in TS patients with mosaicism for a Y derivative chromosome and because association of alopecia universalis and TS is uncommon, fluorescence in situ hybridization (FISH) was performed to search for a second cell population. Our patient was found to have a mosaic 45,X/46,X,+r. FISH analysis using sex chromosome probes permitted us to identify the very small marker as a ring X chromosome, detected in 90% of cells. The ring appeared to be formed almost totally of alphoid sequences with breakpoints in the juxtacentromeric region. The r(X) does not include the XIST locus and may, therefore, not be subject to X-inactivation. Unexpectedly mild phenotype in our patient and its association with alopecia universalis will be discussed.
The authors report the complications noted in the course of 120 cases of typhoid fever. Intestinal hemorrhages and ileal perforations were the most frequent complications observed, respectively, among 12.5% and 3.3% of patients. Neuropsychiatric manifestations were also frequent: 6.7% of cases. Only one death was noted (0.8%). According to this high rate of complications, typhoid fever must be managed under hospital conditions.
