[Ct scan diagnosis of polyostotic fibrous dysplasia with maxillofacial dysmorphia: a case report]. / Diagnostic tomodensitometrique d'une dysplasie fibreuse polyostotique avec dysmorphie maxillo-faciale : a propos d'un cas.

We report a rare case of polyostotic fibrous dysplasia with maxillofacial dysmorphia diagnosed in the radiology department at Hopital Sominé Dolo of Mopti. The aim was to describe the role of medical imaging including the CT scan in its diagnosis. He was a 42-year-old man of rural origin with poor socio-economic conditions. He was sent to us for a craniofacial CT scan for assessment of a maxillofacial mass. This CT scan showed a thickening of the diploid of the vault and the cranial base with osteocondensation and osteolytic lesions at the maxillofacial level. An extension assessment showed polyostotic involvement. His diagnosis is based on medical imaging and in particular CT scan. Three types of radiological aspects are evocative: a homogeneous or heterogeneous clarity, a smoke-like appearance and a slightly condensed appearance. Complications observed were deformities, fracture of the femoral neck and aesthetic damage.

Nous rapportons un cas rare de dysplasie fibreuse polyostotique avec dysmorphie maxillo-faciale diagnostiqué au service de radiologie à l'hôpital Sominé Dolo de Mopti. Le but était de décrire le rôle de l'imagerie médicale notamment le scanner dans son diagnostic. Il s'agissait d'un homme âgé de 42 ans, de provenance rurale avec des conditions socio-économiques défavorables. Il nous a été adressé pour un scanner crâniofacial pour bilan d'une masse maxillo-faciale. Cette exploration scanographique avait objectivé un épaississement du diploé de la voûte et de la base crânienne avec ostéocondensation et des lésions ostéolytiques soufflantes au niveau maxillo-facial. Un bilan d'extension a objectivé une atteinte polyostotique. Son diagnostic repose sur l'imagerie médicale et en particulier la tomodensitométrie. Trois types d'aspects radiologiques sont évocateurs: une clarté homogène ou hétérogène, un aspect en volutes de fumée et un aspect légèrement condensé. Les complications observées étaient les déformations, la fracture du col fémoral et le préjudice esthétique.

Evaluation of femoral nerve blockade following inguinal paravascular block of Winnie: are there still lessons to be learnt?

Lower limb peripheral nerve blocks are used to provide surgical anaesthesia or postoperative analgesia. Anatomical texts imply that femoral and saphenous nerve blocks be evaluated by sensory testing of the skin overlying the anterior aspect of the thigh, and the medial aspect of the foot, respectively. We have mapped the distribution of anaesthesia in 25 adults following femoral nerve blockade, performed using the inguinal paravascular technique of Winnie. There was substantial interindividual variation in the area of anaesthesia. Only the skin overlying the middle third of the medial thigh was consistently blocked in 100% of patients. The distribution of anaesthesia conformed to anatomical text descriptions in 24% of cases. We conclude that demonstration of complete quadriceps paralysis confirms femoral nerve blockade. Failing that, sensory evaluation of a femoral nerve block should involve testing the skin of the middle third of the medial aspect of the thigh. The skin overlying the anteromedial aspect of the middle third of the leg should be evaluated for saphenous nerve block.

Preliminary observations on helminth parasite populations of the dromedary in northern Mali.

An abattoir survey on gastrointestinal parasites of the dromedary (Camelus dromedarius) was carried out in March/April 1987 in northern Mali. Parasitological examination of the digestive tract contents of 11 dromedaries revealed that Haemonchus longistipes was the predominant parasite with a prevalence as high as 85.7%. The genera Impalaia, Trichostrongylus, Cooperia, and Oesophagostomum were also recovered, but with a lower level of infection and frequency. The larval stage of the canine cestode Echinococcus granulosus was recorded in a single instance.
