A Paediatric Hernia with a Twist: The Presentation, Imaging Findings and Management of a Strangulated Ovarian Hernia.

Indirect inguinal hernias are the most commonly encountered congenital abnormality in infants. They may be complicated by herniation of abdominal or pelvic viscus. In girls, a herniated ovary is a relatively common finding, however torsion of the ovary is infrequent. A tender irreducible inguinal hernia in an infant girl should raise the possibility of a strangulated herniated ovary as it requires urgent surgical attention. When in doubt, ultrasound with colour Doppler easily confirms the diagnosis. Here we present the case of an ovarian inguinal hernia which had undergone torsion and review the presentation, imaging findings and management.

The incidence of symptomatic malrotation post gastroschisis repair.

UNLABELLED: Gastroschisis is known to be associated with abnormal bowel rotation. Currently, the broadly accepted practice is not to perform Ladd's procedure routinely at the time of closure of gastroschisis defects. However the incidence of symptomatic malrotation and volvulus post gastroschisis repair is unknown; this incidence is important in view of the current practice of bedside gastroschisis closure. This study examined the incidence of symptomatic malrotation and volvulus following gastroschisis repair. METHOD: Patients who had undergone gastroschisis repair between 1999 and 2009 in any of 2 tertiary centers were identified using the Hospital Inpatient Enquiry system. The medical records were reviewed to obtain demographic data and postoperative outcomes. Patients were contacted for follow-up. RESULTS: 128 patients were identified with a median postoperative follow-up of 4 years (range: 6 weeks to 12 years). Upper gastrointestinal (GI) contrast studies were performed in 30 patients (23.4%), 21 (16.4%) of whom showed evidence of malrotation. Malrotation was documented during the primary repair in 12 patients (9.4%); however Ladd's procedure was performed primarily in only 3 patients. 7 patients underwent Ladd's procedure in a second laparotomy for mechanical obstruction secondary to causes not related to malrotation and volvulus. A total of 29 patients (22.7%) had either operative or radiological evidence of malrotation. None of these patients developed volvulus after being followed for a median period of 4 years. CONCLUSION: Bedside gastroschisis closure without concomitant Ladd's procedure is a safe practice. None of the patients with documented malrotation developed volvulus post gastroschisis repair.

Distribution and determinants of low birthweight in central Sudan.

Two studies were conducted during 1989-90 in Central Sudan to determine the incidence of low birthweight and to ascertain the major risk factors which influence birthweight. In a hospital-based investigation, surveillance of all births was accompanied by a nested case-control study, and in a community based investigation, all midwife-assisted births were studied. There were 4868 and 1523 livebirths among the hospital and community populations, respectively. The incidence of low birthweight was 18.1% in the community and 8.2% in the hospitals. The ratio of term to pre-term low birthweight was 2.9 in the community but only 1.3 in the hospitals. Several risk factors showed consistent and significant associations with low birthweight in the hospital and community studies. Two important and modifiable predictors of term and preterm low birthweight were low maternal weight and malaria infection during pregnancy. Other risk factors included low socio-economic status and, among the hospital population, lack of antenatal care, short birth intervals, poor obstetric history and complications of pregnancy.

Levels and determinants of perinatal mortality in central Sudan.

OBJECTIVES: To determine levels and risk factors for perinatal mortality in Central Sudan. METHODS: Hospital and community based studies were conducted during the period 1989-1990. Of 5328 births registered in the hospital, 197 stillborns and 812 live-born infants were included in a nested case-control study. In the community, a follow-up study was conducted on 1592 midwife-assisted home deliveries. Multivariate logistic regression analysis was used to identify predictors of perinatal mortality and adjusted population attributable risks were estimated to assess the contribution of each factor. RESULTS: The perinatal mortality rate was 85.4/1000 births in the hospital population and 29.4/1000 births in the community population. The major risk factors for perinatal mortality in the hospital and the community studies were similar and modifiable. CONCLUSIONS: To lower perinatal mortality, improvements in maternal nutrition, malaria treatment and control, avoidance of agricultural pesticides during pregnancy, and adequate antenatal and intrapartum care are recommended.
