Evaluation of postgraduate educational environment in a Nigerian teaching hospital.

BACKGROUND: Congenial educational environment (EE) is paramount to effective impartation of knowledge as required in residency training. In this study EE for residency training is evaluated using Postgraduate Hospital Educational Environment Measure (PHEEM). OBJECTIVES: To assess the postgraduate educational environment at the University of Nigeria Teaching Hospital (UNTH), South-East Nigeria, using PHEEM and to determine if there are significant differences in PHEEM scores amongst various sub-groups of resident doctors. METHODS: A cross-sectional study, employing a census survey, involving the administration of validated PHEEM questionnaires to residents in the Departments of Internal Medicine, Obstetrics/Gynaecology, Pediatrics and Surgery in the year 2018. Data entry and analysis were done using SPSS. ANOVA assessed significance of total scores and sub-scale scores. Cronbach's alpha was calculated. RESULTS: A total of 114 Males and 46 females; 93 registrars and 67 senior registrars responded giving 71% response rate. Overall PHEEM score was 85.82; Role autonomy (29.27), Perception of teaching (34.80), Perception of social support (21.55). Males scored more than females in total PHEEM score (p = 0.000, F = 148.235), perception of teaching (P = 0.000, F = 420), and perception of social support (p = 0.000, F = 162.95), but not in role autonomy (p = 0.748, F = 0.104). Registrars scored more than senior registrars in total PHEEM (p = 0.000, F = 67.159), role autonomy (p = 0.000, F = 25.123), Perception of teaching (p = 0.000, F = 18.042) but not in perception of social support (p = 0.31, F = 1.045). There were significant differences in total and subscale scores amongst the specialties. Cronbach's alpha was 0.915. CONCLUSIONS: Postgraduate educational environment in UNTH has more positives than negatives but with room for improvement. There are significant differences in PHEEM scores among various groups of resident doctors.

Practice patterns of preoperative hormonal stimulation in pediatric penile surgeries-A survey of Nigerian pediatric surgeons.

BACKGROUND: Variable practice patterns exist in the use of Preoperative Hormonal Stimulation (PHS) prior to penile surgeries and there seems to be no generally agreed standards. OBJECTIVE: To assess the current practice patterns of PHS before penile surgeries among Nigerian pediatric surgeons and compare with literature. MATERIALS AND METHODS: Self-administered questionnaires were distributed amongst consultants and senior registrars in Pediatric surgery during the 2019 Association of Pediatric Surgeons of Nigeria (APSON) national conference. SPSS version 20 was used for data entry and analysis and results presented as ranges, percentages, tables. Test for association was done using chi square test and a p-value of <0.05 was deemed significant. RESULTS: All fifty respondents comprising 43 males, 7 females; 31 consultants and 19 senior registrars have managed hypospadias, with eighty-six percent managing less than 50 per year. Seventy-six percent practice PHS and more proportion of males use PHS than females (p = 0.027).Only 15.8% and 7.9% respectively estimated serum testosterone before and after PHS. Majority (92.1%) gave PHS because of small-appearing penis and 86.8% have used it in proximal hypospadias. Most commonly used form of PHS was intramuscular testosterone (76.3%) while 2 mg/kg testosterone was commonest dose (65.7%). Ninety-one percent give intramuscular testosterone at 2-4 weeks intervals; ninety-four percent give 2-3 doses of intramuscular testosterone preoperatively with last dose given 2-4 weeks before surgery in 57.9%. Ninety-two percent thought PHS will not increase postoperative complications and pubic hair was most common complication of PHS (63%). DISCUSSION: There is diversity in PHS practices among Nigerian pediatric surgeons. Though mainly low-volume surgeons, majority use PHS before penile surgeries especially in proximal hypospadias and small-appearing penis. Males tend to practice PHS more than females and most commonly used form of PHS is 2-3 doses of 2 mg/kg intramuscular testosterone at 2-4 weekly intervals with last dose given 2-4 weeks before surgery. This study may be limited by bias inherent in self-reported practices and outcomes as seen in surveys, though surveys help to evaluate practices of professionals. CONCLUSIONS: Majority of Pediatric surgeons in Nigeria use PHS in form of intramuscular testosterone mainly for small appearing penis and proximal hypospadias. Most common dosing is 2 mg/kg at 2-4 weeks intervals and 2-3 doses preoperatively with the last dose 2-4 weeks preoperatively. Serum testosterone estimation is not common before PHS. Many believe that PHS does not increase complications following penile surgeries. Current diversity in practice suggests the need for further studies to encourage standardization or guidelines for practice in Nigeria.

Indications, Types and Outcomes of Resections for Acquired Intestinal Conditions in Children.

BACKGROUND: Variable intestinal segments of children may need resection due to congenital or acquired conditions. Resection is done when these intestinal segments are nonviable or dysfunctional. In HICs most resections are for congenital conditions while in LMICs acquired and largely preventable conditions predominate.The spectrum of acquired intestinal conditions leading to bowel resection may also vary between HICs and LMICs. OBJECTIVES: To determine the indications, types and outcomes of intestinal resection for acquired conditions in children. METHODS: A retrospective review of pediatric bowel resections from acquired anomalies over a 10-year period in a tertiary hospital. Data entry and analysis done using SPSS. Fisher's exact test was used to assess level of significance for categorical variables and p-value of <0.05 was adjudged significant. Results are presented as means±SD, ratios, percentages and tables. RESULTS: Fifty-nine males and thirty-three females with a median age of 8 months were recruited. Complicated intussusceptions and right hemicolectomy were the most common indication and procedure respectively. Proportion of right hemicolectomies was more in infants than older children (p=0.0103) while ileal resection was higher in older children (p<0.001). Post-operative complications were seen in 35.8% and mortality rate was 8.7%. CONCLUSION: Complicated intussusception is the main acquired indication for intestinal resection. Right hemicolectomies and ileal resections were done mainly during infancy and beyond infancy respectively.

Disorders of sex development in a developing country: perspectives and outcome of surgical management of 39 cases.

OBJECTIVE: Improvements in diagnostic testing and genital repair have significantly advanced the management of disorders of sex development (DSD). Challenges however, still exist in the management of DSD. This study evaluated the types, challenges of surgical management, and outcome of DSD in south-east Nigeria. METHODS: Retrospective analysis of 39 children with DSD managed from January 2005 to December 2013 at the University of Nigeria Teaching Hospital, Enugu, Nigeria. RESULTS: Types of DSD were: 46, XX DSD in 17 (43.6 %) cases; 46, XY DSD 16 (41 %); Ovotesticular DSD 5 (12.8 %); and one (2.6 %) 46, XY Ovotesticular DSD. Median age at definitive gender assignment was 3 years (range 2 months-14 years). Gender assignment was female for 20 (51.3 %; all 46, XX DSD, one each of 46, XY DSD, Ovotesticular DSD and 46, XY Ovotesticular DSD), and male for 19 (48.7 %; 15 of 46, XY DSD, 4 of Ovotesticular DSD). Eight cases reared as male before presentation required gender reassignment after evaluation and counselling. Genital repair was undertaken at mean age of 4.1 years (range 6 months-14 years). After average follow-up of 22.5 months (range 1 month-7 years), a total of eleven (28.2 %) developed procedure-related complications. Challenges were delayed diagnosis, inadequate diagnostic facilities, and need for gender reassignment. CONCLUSION: There is a wide spectrum of DSD in our setting. Time to diagnosis, evaluation, and outcome may be improved by public enlightenment initiative, focused education of healthcare personnel and provision of relevant diagnostic facilities through enhanced funding and collaboration.
