RESUMEN
Civilian colonic injuries are usually due to penetrating injuries like gun shots, stab wounds and blunt trauma especially following road traffic accidents. Blast injuries are caused by bomb blasts, intracolonic explosion of gases after diathermy, over-enthusiastic bowel insufflation at sigmoidoscopy or by pressure hose applied to the anus. We report the case of a 28-year old man with an unusual blast injury of the colon following a fall from a colanut tree. The transverse colon was sheared off at its two ends while the descending colon was split open along its entire length. There was a delay of 14 hours before the man was discovered in the remote bush and brought to hospital. The mode of injury, its severity and the ultimate favourable outcome are quite unique considering the gross faecal soilage of the peritoneal cavity and the inevitable time lapse before the institution of medical care.

Difficulty in the maintenance of the airway during obstetric anaesthesia is a major contributory factor in anaesthetic related morbidity and mortality. There is an eightfold increase in the incidence of failed intubation in obstetrics. This is attributable to the physiological changes in pregnancy. Eighty consecutive obstetric patients, over a one year period who required general anaesthesia for caesarian section were evaluated using five bedside tests viz: Mallampati test, Thyrometal distance, Sterno-mental distance, Horizontal length of the Mandible and Inter-incisor gap. Eight patients had difficult laryngoscopy (10%). Mallampati test had a sensitivity, specificity and positive predictive value of 87.1%, 99.6% and 70% respectively. The values obtained for the Thyro-mental distance were 62.5%, 93.1% and 50% respectively. The other tests were not able to predict intubation difficulty significantly. When all tests were combined, sensitivity, specificity and positive predictive were values 100%, 36.1% and 14.8%. The combination of Mallampati and Thyro-mental distance had values of 100%, 93.1% and 61.5%--sensitivity, specificity and positive predictive value. Mallampati can be used as the sole predictor of difficult intubation in Nigerian obstetric patients.

Over a 36-month period, prognostic factors in childhood intra-abdominal abscesses were evaluated in fifty-five Nigerian children (38 boys [69.1%] and 17 girls [30.9%] aged 2 months-15 years (mean 8.9, SD 4.3 years). The mortality rate was 20%. The adverse prognostic factors were: a high fever, a positive blood culture, subphrenic location of abscesses, abscesses associated with a typhoid perforation, post-operative abscesses, presence of organ impairment, and multiple abscesses occurring together in the same patient. The age of the patient, duration of illness before hospitalization as well as the number and type of microorganisms cultured from the abscess did not have any influence on the prognosis in the children in this study.

The bacteriology of intra-abdominal abscess in 30 Nigerian children showed anaerobic bacteria constituted 52 per cent of total microflora with Bacteroides fragilis and anaerobic streptococci (19 per cent each) being predominant. E. coli and S. aureus were the predominant facultative bacteria isolated occurring in 24 and 11 per cent, respectively. The incidence of abscess was higher in males than in females and these predominant bacteria were relatively resistant to penicillins, suggesting caution in the use of penicillins in the treatment of intra-abdominal infections.

Forty-one intra-abdominal abscesses in 30 Nigerian children seen over a 2-year period at the Obafemi Awolowo University Teaching Hospital were studied prospectively to determine their location, aetiology, microbiology and clinical course. Thirty-four abscesses (83%) were intraperitoneal with the subphrenic spaces and pelvis being the commonly involved intraperitoneal sites. Six abscesses (15%) were retroperitoneal while there was only one visceral abscess (2%). Diseases of the gastrointestinal tract occurring in 20 patients (67%) were responsible for the majority of intraperitoneal abscesses, while suppurating external iliac adenitis was the major cause of retroperitoneal abscesses. There were 62 microbiological isolates, with 52% being anaerobic bacteria and 47% aerobic bacteria. A fungus, Candida, was isolated once (2%). Escherichia coli and Staphylococcus aureus were the commonest aerobic bacteria, while Bacteroides and anaerobic streptococci were the commonest anaerobes. Sixteen patients (53%) had a mixed flora of aerobic and anaerobic bacteria, while in seven patients each (23%) only aerobic or anaerobic bacteria were isolated. The mortality rate in this series was 23%. Association of an intra-abdominal abscess with remote organ failure, postoperative anastomotic leakage, non-localization of the abscess within the peritoneal cavity and gastrointestinal perforation due to typhoid enteritis was found to portend poor prognosis.
