Unmet Surgical Need among Adults in A Mixed Urban-Rural Community in Nigeria: A Survey of 1,993 Adults Using the Sosas Survey Tool.

INTRODUCTION: Community-based prevalence studies are known to be more accurate than hospital-based records. However, such community-based prevalence studies are uncommon in low- and middle-income countries including Nigeria. Allocation of resources and prioritization of health care needs by policy makers require data from such community-based studies to be meaningful and sustainable. This study aims to assess the prevalence of common surgical conditions amongst adults in Nigeria. METHODS: A descriptive cross-sectional community-based study to determine the prevalence of congenital and acquired surgical conditions in adults in a mixed rural-urban area of Lagos was conducted. The study population comprised resident members in the Ikorodu Local Government Area (LGA) of Lagos State. Data was collected using a modified version of the interviewer-administered questionnaire, the Surgeons OverSeas Assessment of Surgical Need (SOSAS) survey tool. Data was analysed using the REDCap analytic tool. RESULTS: Eight hundred and fifty-six households were surveyed with a yield of 1,992 adults. There were 95 adults who complained of surgical conditions giving a prevalence rate of 5%. Vast majority of reported conditions were acquired deformities (n=94) while only 1 congenital deformity was reported. Others included breast lumps, anterior neck swelling, and groin swellings. CONCLUSION: The most common surgical complaints in our setting among adults were acquired conditions of the extremities and open wounds/sores. With an estimated population of 90 million adults and approximately 1,200 orthopaedic and general surgeons respectively, the surgeon-to-affected population ratio is 1:10,000. There is a large gap to be filled in terms of surgical manpower development.

INTRODUCTION: Les études de prévalence communautaires sont connues pour être plus précises que les dossiers hospitaliers. Cependant, de telles études de prévalence communautaires sont rares dans les pays à revenu faible et intermédiaire, y compris le Nigeria. L'allocation des ressources et la priorisation des besoins de santé par les décideurs nécessitent des données issues de telles études communautaires pour être significatives et durables. Cette étude vise à évaluer la prévalence des affections chirurgicales courantes chez les adultes au Nigeria. MÉTHODES: Une étude descriptive transversale basée sur la communauté pour déterminer la prévalence des conditions chirurgicales congénitales et acquises chez les adultes dans une zone rurale-urbaine mixte de Lagos a été menée. La population étudiée comprenait des membres résidents de la zone de gouvernement local (LGA) d'Ikorodu, dans l'État de Lagos. Les données ont été collectées à l'aide d'une version modifiée du questionnaire administré par un enquêteur, l'outil d'enquête Surgeons OverSeas Assessment of Surgical Need (SOSAS). Les données ont été analysées à l'aide de l'outil analytique REDCap. RÉSULTATS: Huit cent cinquante-six ménages ont été enquêtés, ce qui a donné 1 992 adultes. Quatre-vingt-quinze adultes se sont plaints de conditions chirurgicales, donnant un taux de prévalence de 5 %. La grande majorité des conditions rapportées étaient des déformations acquises (n=94) tandis qu'une seule déformation congénitale a été signalée. Les autres incluaient des nodules mammaires, des gonflements antérieurs du cou et des gonflements inguinaux. CONCLUSION: Les plaintes chirurgicales les plus courantes dans notre cadre parmi les adultes étaient des conditions acquises des extrémités et des plaies ouvertes/ulcères. Avec une population estimée à 90 millions d'adultes et environ 1 200 chirurgiens orthopédiques et généralistes respectivement, le ratio chirurgien-population affectée est de 1:10,000. Il y a un grand écart à combler en termes de développement de la main-d'œuvre chirurgicale. MOTS CLÉS: Prévalence, Charge de morbidité, Chirurgie, Plaies.

Two-stage flap repair of severe hypospadias: Usefulness of the tubularized incised plate urethroplasty.

PURPOSE: The use of flaps in the two-stage repair of posterior hypospadias associated with severe chordee has been well established. Despite the almost certain guarantee of flap take, complications such as diverticuli are still relatively high. While different applications of the tubularized incised plate have been described, experience with the application of the technique to the two-stage flap repair is very limited. A previous local review of 15 cases performed at the present institution during the period 1998-2003, using the technique as described by Rekit, revealed fistulae and diverticulum rates of 20% and 27%, respectively. With the primary objective of improving surgical outcome, the midline incision was incorporated into the two-stage flap repair. MATERIALS AND METHODS: Between 2004 and 2015, 35 boys (aged 2-15 years) with severe hypospadias that required excision of the urethral plate were operated using the two-stage flap technique. The first stage involved mobilization of preputeal or dorsal penile skin (if circumcised) to the ventral surface, as described by Retik. After a minimum interval of 6 months, the second-stage operation was performed in a way similar to the technique of tubularized incised plate urethroplasty, as popularized by Snodgrass, and involved a preliminary midline incision on the neo-urethral plate followed by tubularization and multilayered closure. RESULTS: All but one flap took successfully. The outcome was satisfactory in 80% of patients, and there was a fistula rate of 14% ( Summary Table). One patient had a complete breakdown of the flap and was successfully treated about 12 months later by repeating the second stage of the operation. No case of diverticulum or stricture was recorded. DISCUSSION: Even though there was a marginal improvement in the fistula rate, the most striking observation was the complete absence of diverticulum or stricture. With a reported incidence rate of 20-63%, different authors have reported diverticulum formation (despite the absence of distal obstruction) to be a major problem of the two-stage flap technique. Attempts by these authors at reducing the risk of diverticulum by reducing flap size have tended to increase the risk of strictures. This has been the main reason given by some authors for abandoning the technique. The main limitations of the present study included the wide age range of the patients and the small sample size. CONCLUSION: The inclusion of a midline incision in a two-stage flap urethroplasty for proximal hypospadias appears to prevent the development of diverticulum.

Routine hemoglobin electrophoresis for pediatric surgery day case in at-risk populations: Suggested algorithm for screening using clinical risk factors.

BACKGROUND: Hemoglobin electrophoresis (HBE) is a part of the preoperative routine requested by anesthetists. However, the prevalence of hemoglobinopathy in the population is low. This study aims to determine the clinical risk factors for hemoglobinopathies and propose clinical guidelines for preoperative screening of patients for pediatric day care surgery. PATIENTS AND METHODS: A prospective study carried out over 12 months. Consecutive patients aged 6 months and older who had day case surgery were recruited to the study. Biodata and relevant clinical data were collated and documented in a proforma and analyzed using a statistical package for social sciences version 17. RESULTS: There were 124 patients106 boys and 18 girls. The median age was 3 years. Scrotal lesions were the most common conditions managed (71.7%). Seventy-eight percent of patients had HbAA, 15.3% had HbAS, and 4.8% had HbAC while 0.8% each had both HbSC and HbSS. At least one parent of 78.2% knew their Hb phenotype, of which, 79% were HbAA. A history of jaundice (P = 0.0001), hand and foot syndrome (P = 0.0001), frontal bossing (P = 0.0001), and low packed cell volume at surgery (P = 0.001) were found significant in predicting hemoglobinopathies. There was no mortality. CONCLUSION: Risk factors for hemoglobinopathies from this study included a positive history of jaundice, hand and foot syndrome, frontal bossing, and anemia. Proposed guidelines for HBE screening include the presence of hemoglobinopathy in one parent if one parent has sickle cell trait, and the other parent's genotype is unknown or if any of the risk factors is present.

H-type tracheo-oesophageal fistula: a diagnostic challenge in a resource-poor country. A case report.

H-type fistula is a rare form of congenital tracheo-oesophageal fistula accounting for 4% of all cases of Tracheo-oesophageal fistula. The typical picture is that of recurrent chest infection due to both missed and delayed diagnosis as well as cyanosis and choking during feeds. In resource poor countries this problem is further exaggerated by ignorance, poverty and lack of access to basic investigative modalities. This is the case of [abstract incomplete].

Routine haemoglobin electrophoresis screening in day case herniotomy in Nigerian children: Is it evidence-based?

BACKGROUND: To determine the prevalence of haemoglobinopathies in children who require day case herniotomy in our centre and ascertain if routine screening is necessary in all patients who require herniotomy. MATERIALS AND METHODS: A 12-month retrospective analysis of patients requiring herniotomy in our centre. Data including age, sex, diagnosis, haemoglobin electrophoresis status, surgical outcome and hospital stay were analysed. RESULTS: Ninety-five patients had complete records. There were 84 boys and 11 girls. M:F ratio: 7.6:1. The mean age was 3.2 ± 0.6 years. Fifty-five point eight per cent of the patients had right inguinal hernias while 35.8% had left inguinal hernias. Eight patients (8.4%) had bilateral inguinal hernias. Twenty-six patients (27.4%) had haemoglobinopathies while 69 patients (72.6%) had homozygous Haemoglobin A. The Sickle Cell trait (HbAS) was found in 22 patients (23.2%) while the HbAC was found in three patients (3.2%). One patient (1.1%) had Sickle Cell disease (Haemoglobin SS). He had had blood transfusion and previous history of jaundice. All patients survived and all patients were discharged on the day of surgery (mean hospital stay: 4hrs (range: 2.5 hrs-12 hrs)) except the patient with Sickle Cell disease who was admitted a day before surgery and discharged a day after the operation. CONCLUSION: One in four children coming for day case herniotomy in our centre had the Sickle Cell trait while only 1% had the Sickle Cell disease. These findings are in keeping with the prevalence in the Nigerian population. Routine screening may not be necessary for all patients coming for herniotomy in our centre. Clear indication(s) should be outlined for screening.

Urinary kallikrein in normal and hypertensive pregnancies.

Urinary kallikrein was measured in normal pregnant women stages of gestation and in women who developed hypertension in late pregnancy. Mean urinary kallikrein was highest in the first trimester and fell significantly in the third trimester to nonpregnosterone system. A negative correlation was observed between urinary kallikrein and the length of gestation in normal pregnancy. Urinary kallikrein fell significantly below nonpregnant levels in patients with hypertension while the renal excretion of sodium and water was not different from that in normal pregnancy of the same dy is discussed in the light of factors known to increase kallikrein excretion. It is considered unlikely that this elevation is due to the escape from the sodium-retaining effect of the high aldosterone of pregnancy. It may be due in part to the stimulating effect of raised angiotensin II levels but it is considered most likely to be the effect of a circulating renal vasodilator. The reduced kallikrein in hypertension of pregnancy may play a part in the development of the hypertension and resembles the reduced kallikrein excretion in essential hypertension.
