[Treatment of vesicovaginal fistulas using the musculofascial flap of the levator ani muscle: 26 case reports]. / Le traitement des fistules vésicovaginales par l'utilisation du lambeau musculofascial du muscle releveur de l'anus: à propos de 26 cas.

OBJECTIVE: The authors reported the preliminary results of levator ani muscle flap in the treatment of vesicovaginal fistula. MATERIALS AND METHODS: Twenty-six patients whose age varied between 13 and 18 years (mean: 30 years) are selected. All the patients are treated by the vaginal approach using the part of superficial rectal fibers of the levator ani muscle. RESULTS: Among the 26 patients, 14 are free after the first cure of vesicovaginal fistula (54%), and 4 patients (15%), after the treatment of some complications. CONCLUSION: The musculofascial levator ani flap with its vascular pedicle and its mobilisation can successfully close the vesicovaginal fistula. The preliminary results obtained (88%) tie up with that previously described in the literature.

Extraordinary feeding behaviour in Diptera Sciomyzidae, snail-killing flies.

In the laboratory, the larva of Sepedonella nana, Diptera Sciomyzidae, were only able to develop at the expense of small aquatic oligochets collected in adult habitats. Up till now, larval cycles have been elucidated for 38% of the Sciomyzidae; all these larvae proved to be strict consumers of aquatic or terrestrial molluscs (including slugs). This specific predation was considered as a major distinguishing characteristic of Sciomyzidae among Diptera. The unusual nutritional behaviour of S. nana reported in the present note is in contradiction with well-established prior knowledge. The species presented all the characteristics of the family, particularly the ventral arch sclerite present on the larva cephalopharyngeal skeleton. It was considered as a derived species; this behaviour, probably of secondary type, revealed new nutritional types for Afrotropical Sciomyzidae for which the biology of only five species was elucidated out of about 60 species described.

[A new monogenean parasite (Bouixella n. g.) in the Mormyridae (teleosts) of Benin]. / Découverte de Monogènes (Bouixella n. g.) chez les mormyridae (Teleostei) au Bénin

Study of the Monogenean gill parasites occuring in the Mormyrid fish from Benin (Africa). Description of a new genus, Bouixella. It differs from the other Ancyrocephalidae by the number (4) of cross bars between the haptoral hamuli. This new genus seems to bee specific of the mormyridae among which a new example of simultaneous gill parasitism by congeneric species is reported.
