Adding sufentanil to levobupivacaine or ropivacaine intrathecal anaesthesia affects the minimum local anaesthetic dose required.

Background: We carried out this prospective, randomized, double-blind study in order to evaluate whether the intrathecal addition of sufentanil 3.3 mcg affects both the minimum local anaesthetic dose (MLAD) of spinal levobupivacaine and ropivacaine for a caesarean section and enhances the spinal block characteristics.

Methods: One hundred and eighty women were randomly allocated into four groups: levobupivacaine (Group L), levobupivacaine plus sufentanil (Group L+S), ropivacaine (Group R) and ropivacaine plus sufentanil (Group R+S).

[Anatomicopathological aspects of genital bilharziasis in women].

The localisations of the genital bilharziosis of the woman are not very known. However, they are responsible of many functional sequelae: pelvic aches, menstrual troubles, aberrant nidations, spontaneous abortions, permanent sterilities. From 43 anatomic taking investigated from 1971 to 1982 and from the literature they have collected, the authors successively study the localisations of the genital bilharziosis on ovary (21 %), uterine tube (16 %), uterine cervix (42 %), vulva, vagina and clitoris (21 %).

Field studies of a reusable polyamide filter for detection of Schistosoma haematobium eggs by urine filtration.

A reusable monofilament polyamide (Nytrel) filter and ninhydrin stained paper filter were compared in syringe filtration of urine to detect Schistosoma haematobium eggs in the urine under field conditions. The sensitivity of the technique using the Nytrel filter was similar to that of ninhydrin stained paper filters. The quantitative geometric mean S.
