Depressed Skull Fractures in Children: Treatment Using an Obstetrical Vacuum Extractor

Introduction: A depressed skull fracture is an inward buckling of the skull bones. It is referred to as a ping-pong ball fracture in neonates; in older children, some fractures take a cup shape mimicking ‘ping-pong’ ball fractures. Objective and Methods: The aim of this study was to assess the use of an obstetric vacuum extractor to elevate cup-shaped depressed skull fractures in children irrespective of age. All children admitted into the Central Hospital of Yaounde between 1999 and 2004 with a cup-shaped simple depressed skull fracture and treated with the vacuum extractor were included. Results: Nine children aged from 3 months to 17 years were treated with the vacuum extractor. The cosmetic and radiographic results were satisfactory. The procedure was simple and without any complication. Conclusion: The elevation of ‘ping-pong-ball-like’ or ‘cup-shaped’ skull fractures in older children (beyond the neonatal period) is a simple, effective and safe procedure.

Strangulated or incarcerated spontaneous lumbar hernia as exceptional cause of intestinal obstruction: case report and review of the literature

Lumbar hernias are rare conditions and about 300 cases have been reported since the first description by Barbette in 1672. Therefore strangulation or incarceration are also exceptionally encountered. We present a 62 -year-old-man who had strangulated left lumbar hernia and consequent mechanical small-bowel obstruction, alongside with a non strangulated right lumbar hernia. Through a median laparotomy, an intestinal necrosis was found. A bowel resection with end to end anastomosis was performed and the lumbar hernias were repaired on both sides. The recovery was uneventfull. To the best of our knowlwdge thanks to the litterature review presented here, this is the 19th case of incarcerated or strangulated spontaneous lumbar hernia described in the surgical litterature since 1889.

Feasibility of a simple drainage system in Cameroonian children after thoracotomy and decortication for empyema thoracis

BACKGROUND To analyse the outcome of children with empyema thoracis treated by decortication followed by a simple drainage system. PATIENTS AND METHODS Retrospective chart review from July 2001 to June 2010 of all cases of children who had a thoracotomy for empyema. We used an endotracheal tube as chest drain and a urinary bag as a collector. Statistical analyses were done using EXCEL and SPSS 9.0. RESULTS Forty one children underwent thoracotomy and decortication for empyema, there were 23 boys and 18 girls with a sex ratio of 1, 21. The mean age was 2½ years with a minimum of 1 month and a maximum of 15 years of age; 27 children were below two years of age. All the patients have received antibiotic for a long period before surgery. The culture was negative, except in two cases where we found Klebsiella pneumonia and Staphylococcus aureus. In five cases, the empyema was due to Mycobacterium tuberculosis. Three children presented a complication: One child had a persistent purulent drainage for 2 weeks; another one was re-operated upon because of necrotic lung abscess and one child died of sepsis. In most cases, the chest tube was removed between day 4 and day 6 post-operatively. The average length of hospital stay after the surgery was 10 days. CONCLUSION Thoracotomy and decortication in children with empyema can be safely done in Cameroon using a simple drainage system with good results compared to those in the literature.

Paediatric fractures in a sub-saharan tertiary care center: a cohort analysis of demographic characteristics, clinical presentation, therapeutic patterns and outcomes

Introduction Paediatric fractures are often of good prognosis due to auto-correction of insufficient fracture reduction by bone remodeling. In sub-Saharan Africa, traditional healers are renowned for managing fractures and there is a neglect for specialized pediatric fracture care. We aimed to determine the demographic characteristics, clinical presentation, treatment patterns and outcomes of paediatric fractures in a tertiary health care centre in Yaoundé. Methods We conducted a prospective cohort study of all consenting consecutive cases of fractures in patients younger than 16 years managed between January 2011 and June 2015 at the University Teaching Hospital, Cameroon. We analysed demographic data, injury characteristics, fracture patterns, treatment details, therapeutic challenges and outcome of treatment at 12 months of follow-up. Results We enrolled 147 fractures from 145 children with a mean age of 7 years and male-to-female sex ratio of 2.5:1. The main mechanisms of injury were games (53%) and accidental falls (20.7%). Forearm fractures were the most common fractures (38%). The mainstay of management was non-operative in 130 (88.5%) fractures, with 29.3% manipulations under anesthesia and 17 (11.5%) open reductions with internal fixation. The most surgically reduced fractures were supracondylar humeral fractures. Major difficulties were long therapeutic delay, lack of diligent anaesthesia and the lack of fluoroscopy. The outcome of treatment was favorable in 146 (99.3%) paediatric fractures. Conclusion With the growing population of sub-Saharan Africa and the objective of becoming an emergent region, public policies should match the technical realities.

A case report of Cowper's syringocele in an 18-months old infant at the Yaoundé Gynaeco-Obstetric and Pediatric Hospital

Syringocele or dilatation of the duct of the bulbo-urethral (Cowper′s) gland is usually of congenital origin but can be acquired. It is a very rare deformity, <10 cases have been reported in literature. The main objective is to describe an additional case of syringocele of Cowper′s glands and review the literature. An 18-month-old infant presented with a history of acute urinary retention 3 days after birth and a cystostomy was done. Voiding cystourethrogram was normal and cystourethroscopy showed a syringocele. Endoscopic incision was performed in our patient with satisfactory results. No complications were noted. Syringocele or cystic dilatation of Cowper′s gland duct usually has a congenital aetiology. Diagnosis is confirmed by endoscopy. Treatment is by marsupialisation in the urethra by endoscopy. Syringocele is a rare pathology usually congenital. It should be suspected in all case of lower urinary tract obstruction in children.

Mixed gonadal dysgenesis in Yaoundé: A preliminary experience about three cases

Mixed gonadal dysgenesis is characterised by unilateral chromosomal abnormality, which is probably the result of anaphase lag during mitosis. The 45, XO/46, XY karyotype is the most common form of mosaicism involving the Y chromosome. It is a rare clinical entity with a worldwide incidence of 1.5/10,000 live births. Its epidemiology in Sub-Saharan Africa is not known. This study reports experience in the management of 3 cases at the Yaounde Gynecologic-Obstetric and Paediatric Hospital. From November 2009 to November 2014, 3 cases were successfully managed at our institution. Results: All patients presented with asymmetrical gonadal differentiation. On one side of the body, a poorly-developed testicular gonad and on the other side a gonadal streak. A persistent Mόllerian remnant was equally found in the 3 cases. Management of mixed gonadal dysgenesis should be done in tertiary health care centres. A multidisciplinary team approach is recommended.
