[Hip paraosteoarthropathy after sciatica nerve injury by quinine intramuscular injection]. / Paraostéoarthropathie de la hanche sur lésion du nerf sciatique par injection intramusculaire de quinine.

INTRODUCTION: Often occurring in central nerve injuries, paraosteoarthropathic conditions are revealed by a stiffness or ankylosis of the joint. Their occurring during peripheral nerve injuries is rare. OBJECTIVE: To report a case of hip paraosteoarthropathy features after sciatica nerve injury by quinine intramuscular injection. MATERIALS AND METHOD: We report a case of a 24-year-old patient presenting with pain, oedema of the left buttock, limitation of bending of the left hip, and antalgic limping associated with a small step because of axonal left sciatic nerve injury. Initial pelvis X-ray and laboratory findings were normal. Reviewed 4 months later with important stiffness of the left hip, a second X-ray showed an atypical paraosteoarthropathy (POA). Chemotherapy and physiotherapy alleviated neurological muscle weakness but did not have any effect on the hip functionality. Surgical excision was the only treatment that improved the amplitude of movements. Evolution 7 years later showed the disappearance of the peripheral nerve-injury signs and the conservation of the movement amplitude obtained after excision, without a return to normal. CONCLUSION-DISCUSSION: Factors pointing to this POA were initial oedema, immobilization because of pain, and trauma by quinine intramuscular injection. The interest is the exceptional occurrence of POA on a peripheral nerve injury (sciatica nerve injury by quinine injection) outside the context of length resuscitation and that sciatica nerve injury is frequent in tropical countries but anachronistic in a developed one.

[Urinary calculi in the Surgical Departments of the National Hospital Center and the University of Cotonou]. / La lithiase urinaire dans les services chirurgicaux du Centre National Hospitalier et Universitaire de Cotonou.

The authors review renal stone disease in the National University Hospital of Cotonou on the basis of 109 cases observed over a period of 18 years. The mean frequency was 6.11 cases per year with a marked male predominance (sex ratio of 3.73). Infection and diseases of the lower urinary tract play an important aetiological role, hence the numerical importance of cases of lower tract stones (60.95%).

[Urethral mucosal prolapse in children at the National Hospital and University Center of Cotonou. Apropos of 13 cases]. / Le prolapsus muqueux uréthral de l'enfant au CNHU de Cotonou. A propos de 13 observations.

The authors report 13 cases of prolapse of the urethral mucosa. This is a benign lesion of the terminal portion of the urethra, seen above in black girls aged from 6 to 10 years. The usual presentation is vulval bleeding. The lesion is recognised by inspection and urethral catheterisation. Resection of the prolapse with muco-mucosal suture, not followed by the insertion of an indwelling catheter, is adequate and may be performed in a day hospital.
