Tumeur glomique de la capsule antérieure du coude. À propos d’un cas

Glomus tumors are rare tumors, benign but painful and responsible for a major functional impairment. Although their preferential localization is digital, 35% of glomus tumors are extradigital. Ignorance of this disease characterized by atypical clinical signs and the absence of specific imaging are responsible for a significant diagnostic delay, 7 to 10 years in extradigital forms. Treatment by surgical excision simply ensures immediate disappearance of pain without recurrence in 90% of cases. It is therefore necessary to emphasize the existence of this sometimes debilitating condition benefiting from effective therapeutic solution. We report the case of a glomus tumor of the anterior capsule of the left elbow in a 24-year-old woman with a diagnostic delayed by 12 years.     

Embolie gazeuse d’origine veineuse chez un enfant

A 4 year old girl is referred to our institution for resection of a nephroblastoma with an extension of the tumor into the lumen of the inferior vena cava. To perform a correct resection of the tumor, the operation was conducted under cardiopulmonary bypass. At the end of the procedure, a bilateral mydriasis was noticed. A CT-scan concluded to a massive venous air emboli. As the procedure was unventful, and no other cause of air emboli was found, the etiology of this emboli is problably retrograde because of the large opening of the inferior vena cava that was required to remove the tumor. To avoid similar case the use of transcranial doppler monitoring may be of interest.     

Compression du rameau superficiel du nerf radial par un kyste synovial du coude (À propos d’un cas et revue de littérature)

Compression of the radial nerve at the elbow is quite rare; entrapment of its superficial branch is exceptional. Extrinsic compression is the most frequent etiology. Magnetic resonance imaging plays a major role in the diagnosis, and early surgical excision or echoguided drainage – in case of synovial ganglion – allows a total recovery. The authors report the case of a compression of the superficial branch of radial nerve by an elbow synovial cyst treated by surgical resection.     

Une luxation antérieure du coude sans fracture péri-articulaire chez un adulte

In view of the comparative frequency of posterior dislocations of the elbow, it is rather remarkable that anterior dislocations of that joint should be among the rarest of injuries [1]. Our case is one of the first cases of anterior dislocation of the elbow without any periarticular fracture or pre-existing deformities around the elbow [2].     

Traitement de l'hypovolémie chez le traumatisé craniocérébral

The appropriate administration of intravenous fluids in neurosurgical patients remains an area of disagreement between neurosurgeons and anaesthetists. Fluid restriction has long been advocated by the former and is widely believed to reduce or prevent the formation of cerebral oedema. However, such restriction can lead to hypovolaemia which in turn can result in haemodynamic instability. Thus, brain homeostasis should be aimed for through adequate fluid administration and normal or slightly elevated mean arterial pressure. The properties of the endothelium differ between the brain and the remainder of the body. In most non CNS tissues the size of the junctions between endothelial cells averages 65 Å. Proteins do not cross these gaps while sodium does. In the brain, the junction size is only 7 Å, which is too small to allow crossing by sodium. Investigations with changes in osmotic and oncotic pressure have demonstrated that : 1) reducing osmolality results in oedema formation in all tissues including normal brain ; 2) a decrease in oncotic pressure is only associated with peripheral oedema but not in the brain ; 3) in case of brain injury, a decrease in osmolality elicits oedema in the part of brain which remained normal ; 4) similarly, a decrease in oncotic pressure does not cause an increase in brain oedema in the injured part of the brain. Thus, a major reduction in oncotic pressure is unimportant for the brain, whereas changes in total osmolality are the dominant driving force at this level. To conclude, in a hypovolaemic patient with severe head injury, the cristalloid of choice is NaCl 0.9 % and the colloid of choice is hydroxyethylstarch, both with an osmolality > 300 mosm · kg⁻¹. Ringer-lactate is hypoosmotic (255 mosm · kg⁻¹) and may cause or increase cerebral oedema. Mean arterial pressure should be maintained above 80 mmHg.     

Fracture du scaphoïde carpien associée à une fracture de l’extrémité inférieure du radius chez l’enfant. À propos de deux cas

The authors report two cases of concomitant scaphoid and distal radial fractures, a rare combination of lesions in children. The first case was in a 14-year-old boy who presented a midscaphoid fracture associated with a distal forearm fracture. The second case concerned a 13-year-old boy who presented a midscaphoid fracture associated with a Salter type II distal radial fracture. Both fractures were reduced under general anaesthesia. The total period of immobilisation was 3 months, using a large arm thumb cast. Associated scaphoid fractures should be suspected with all types of distal forearm injuries in children. Reduction of the radius fracture should be done carefully to avoid possible displacement of the scaphoid fracture.     

Contribution à l’étude de la mortalité dans un service d’urologie: Le cas du service d’urologie du CHU de Cocody d’Abidjan de 2000 à 2006

Objective

To analyze the incidence and main causes of mortality in the Department of Urology of the University Hospital of Cocody.

Patients and Methods

This retrospective analysis included 117 patients who died in the Department of Urology of the University Hospital of Cocody between April 2000 and December. Based on the data collected from the patient files, the hospital registry and the death certificates we studied the frequency and causes of death.

Results

The overall mortality rate was 10.1% with a male-to-female sex ratio of 14:1. The patients’ mean age was 63.4 (range 18–94) years. The main cause of death was cancer (87.5%). Cancer of the prostate which was the second most frequent reason for consultation after benign prostatic hyperplasia was the commonest cause of death encountered in 62.4% of the patients, followed by bladder and renal cancer with 16,2% and 6%, respectively. Prostatic adenoma (52%) was the most frequent and urethral stricture (8%) the third most frequent reason for hospitalization and led to death in 3.4% and 4.3%, respectively. Moreover, death mainly occurred in the second half of the month (53.9%) and during the night (57.3%).

Conclusion

The incidence of mortality in urology remains high and is almost exclusively related to urological cancers.     

Traitement de l’hydrocéphalie de l’enfant par ventriculocisternostomie endoscopique au Sénégal

IntroductionSince its advent, endoscopic third ventriculostomy (ETV) has been an effective alternative to shunt placement for the treatment of hydrocephalus. The aim of this study was to report the results of our experience with this technique in children in Senegal.Materials and methodsThis was a retrospective study of 70 cases of children aged between 5 months to 15 years who were treated by ETV in the Neurosurgery Department of Fann Hospital in Dakar, between January 2010 to December 2012. The results were evaluated based on the clinical criteria of Drake and the Canadian Pediatric Neurosurgery Study Group. The mean follow-up duration was 24 months (9–32 months).ResultsThe mean age at diagnosis was 29 months. A male predominance (sex-ratio 1/3) was observed. We also noted a macrocephaly in 64.4 % of cases, psychomotor retardation in 40 % and decreased vision in 31.4 %. Headache and vomiting were found in 42.8 % and 61.4 % respectively. The main etiology was a stenosis of the mesencephalon aqueduct (30 %), followed by a Dandy-Walker malformation (25.7 %). Significant intraoperative bleeding was found in 2.8 % of patients. The most common postoperative complication was CSF leakage (18.6 %), followed by infections (14.2 %). The success rate according to the clinical criteria of Drake was 71.4 %. This success rate was influenced by the age of patients and the hydrocephalus etiology. No deaths occurred.ConclusionThe endoscopic third ventriculostomy is a simple, safe and effective technique. Its advantages in terms of quality of life and morbidity compared with bypass valves makes it the technique of choice, particularly in developing countries.     

Lambeau hétéro-digital selon le principe du « doigt banque » prélevé chez un orteil dupliqué pour le traitement d’un flessum cutané d’une clinodactylie associée

IntroductionThe correction of cutaneous deficiency encountered in clinodactyly is an important aspect of its treatment. The use of the skin lining of an adjacent duplicated toe as a « spare-part » flap may be of interest in providing good quality tissue.Clinical caseWe report the case of a child with complete duplication of the 5th toe associated with clinodactyly. The use of a heterodactyl flap taken from the amputated toe allows the release of a plantar cutaneous flange of the preserved toe.DiscussionThe concept of « spare-part » flap is mainly used in hand surgery in traumatic lesions of the fingers. Its application in the treatment of clinodactyly on the occasion of the regularization of a polydactyly is also interesting because some fingers or toes are intended to be amputated to render a classical anatomy of five-toed foot. It is necessary for the realization of this type of flap on malformative toes to verify the existence of a distinct viable pedicle of the amputated toe, which can be done only intraoperatively.ConclusionThe surgery for congenital malformations of the toes requires perfect management of the skin capital. The use of a « spare-part » toe flap taken from the toe to be amputated is a viable solution for the treatment of a cutaneous flessum encountered in a clinodactyly of the adjacent finger.
