Point prevalence of Cryptosporidium oocyst in calves grazing along River Rima bank in Sokoto, Nigeria.

The present study was conducted to investigate the point prevalence of Cryptosporidium oocysts infection in calves grazing along the bank of Rima River Sokoto in October 2011. The river bank is a converging zone for domestic animals reared in different quarters of the town and the surrounding settlements. A total number of 2,959 cattle were enumerated out of which 147 (4.97%) were calves. Faecal samples were collected from 100 (68.02%) calves by convenient sampling technique. Formol-Ether sedimentation and modified Ziehl-Neelsen staining techniques were used to identify the Cryptosporidium oocysts in the faecal samples. Faecal consistency was also used to identify diarrhoeic and non-diarrhoeic calves. Cryptosporidium oocysts were identified in 33 (33.0%) of the calves examined. The detection rate was higher among the male calves (38.46%) than females while the Rahaji breed had the highest prevalence of 62.5%. A total of 6 (18.18%) among the positive cases were diarrhoeic. The differences in prevalence based on sex, breeds and presence of diarrhoea were not statistically significant. Calves may become sources of Cryptosporidia infection to man and other animals in the study area through unrestricted movements and interactions with the environment.

A randomised controlled trial of uterine exteriorisation and non-exteriorisation at caesarean section.

BACKGROUND: There is not enough information to evaluate the routine use of exteriorisation of the uterus for repair of the uterine incision and further studies are needed to examine the value of exteriorisation of the uterus at caesarean section as against non-exteriorisation. AIMS: To assess intraoperative and postoperative morbidity following exteriorisation of the uterus at caesarean section as compared to those with non-exteriorisation. METHODS: A randomised controlled trial at Obafemi Awolowo University Teaching Hospital, Ile Ife, Nigeria. Two hundred and ten women were randomised to either exteriorisation (N = 105) or non-exteriorisation group (N = 105). Statistical analysis using SPSS compared intraoperative and postoperative outcome. The outcome measures include intraoperative blood loss, number of analgesic dose, difference in operating time, febrile morbidity, intraoperative complications, and duration of hospital stay. RESULTS: There were significant reductions in intraoperative blood loss (P < 0.05), number of analgesic dose (P < 0.05) and duration of hospital stay (P < 0.05) in the uterine exteriorisation group as compared to those in the non-exteriorisation group. There was no significant difference in operating time, febrile morbidity, intraoperative complications and operating time. The period for return of bowel function was significantly longer in the exteriorisation group. CONCLUSION: Exteriorisation of uterus at caesarean section is associated with less intraoperative blood loss, less number of analgesic dose and shorter hospital stay.
