[Transvaginal estrogen therapy in urinary stress incontinence]

Thirty-four postmenopausal stress incontinence patients were divided in two groups: 17 were treated with 0.5 mg oestriol vaginal cream for 90 days, 17 controls were treated with moisturizing cream. All had low urethral pressures and dystrophy. Treated patients showed improvement of maximum urethral pressure, urethral closure pressure, and volume at first sensation of fullness. Dystrophy was cured in most patients; in 17% incontinence was cured and in 41% subjectively improved.

[An atypical case of visceral leishmaniasis]

The authors report a case of infant visceral Leishmaniosis observed in their Department, that showed unusual clinical finding (absence of fever). They emphasize the current epidemiologic situation and recommend to consider the disease in the diagnosis of long term syndroms occurring without fever and with hepatosplenomegaly.

Homozygous and heterozygous homologous chromosomes: effects on preferential pairing and recombination frequency in wheat

Trisomics for chromosomes 1A and 6B of wheat backcrossed to euploids showed progeny with unexpected segregation frequencies (cytological and genetical) that can be attributed to preferential pairing between homologues. Recombination frequency between the centromere and a gene for mildew reaction of chromosome 1A showed an increase from the first to the second backcross that could be attributed to a positive correlation between homozygosity and the degree of pairing between homologous chromosomes. The use of wheat trisomics for genetic analysis is also discussed.Key words: preferential pairing, trisomic segregation, wheat cytogenetics, recombination frequency, pathogen reaction.
