[Salmonella enteritidis arthritis complicating systemic lupus erythematosus]. / Arthrite à Salmonella enteritidis compliquant un lupus érythémateux systémique.

Septic arthritis due to Salmonella in systemic lupus erythematosus is rare. We report a case of septic arthritis by Salmonella enteritidis which occurred during the evolution of systemic lupus erythematosus. A 23-year-old man was diagnosed as suffering from systemic lupus erythematosus. This diagnosis was taken on the basis of general symptoms, skin lesions, hemolytic anemia, thrombocytopenia and glomerulonephritis (class III). He was treated with three methylprednisolone boli related by high-dose regimen of prednisolone. A month and a half later, he presented fever with monoarthritis of the left elbow without any other new sign of underlying systemic disease. Bacteriological examinations isolated S. enteritidis. The patient improved with antibiotics and joint lavage. Feverish monoarthritis in systemic lupus erythematosus should be suspect to be septic arthritis. Appropriate treatment should be promptly instituted to improve the prognosis.

Pelvic bone hydatidosis.

Bone hydatid disease is a rare pathology, characterized by its long clinical latency, the absence of radiological specificity as well as its challenging surgical treatment. We report an observation of pelvic bone hydatidosis in a 28-year-old patient, appearing with pain and stiffness of the hip as well as a degenerative aspect on the coxofemoral joint on X-ray. The treatment consisted of an extensive hemipelvectomy with femoro pelvic arthrodesis, completed by medical treatment. The functional result was excellent in spite of a break in the fixation material, which allowed a certain mobility at the proximal end of the femur. Hydatid disease of bone is infiltrating,diffuse, slow, and progressive, all characteristics explaining the often-delayed diagnosis. Medical imaging provides accurate analysis for planning a broad surgical resection. The quality of surgical resection is determined according to the risk of recurrence. Pelvic locations are particularly difficult to treat. After an enlarged and difficult surgical resection, reconstruction remains aleatory and poses many technical problems.

Results of surgical treatment of congenital convex pes valgus (ten nonidiopathic feet).

PURPOSE OF THE STUDY: Congenital pes valgus is a rare and complex deformity of the foot raising serious diagnostic and therapeutic challenges. The purpose of our work was to present the surgical procedures used in our series and to analyze outcome. MATERIAL AND METHODS: Ten feet presenting congenital convex pes valgus treated surgically over a six-year period using the same operative technique were reviewed at minimum five years follow-up. Idiopathic deformities were excluded from this series. Deformities were secondary to arthrogryposis in five feet, multiple malformative syndrome in four, and diastematomyelia in one. The surgical technique used two approaches: a posteromedial incision to release the dorsal flexors, disinsert the tibialis posterior, open the talonavicular joint, release the Achilles tendon and release the posterior tibiotalar capsule; a lateral incision to lengthen the fibular tendons and perform an osteotomy of the anterior process of the calcaneum. A talonavicular pin and a calcaneocuboid pin maintained the correction. The tibialis posterior tendon was reinserted on the anterior aspect of the talonavicular capsule after incision of the dislocation chamber. RESULTS: Outcome was considered good in five cases and fair in five. Outcome was fair in the arthrogryposis feet. Under correction was observed in two feet and valgus flatfoot in three. Talar necrosis occurred in one foot and navicular necrosis in two. DISCUSSION: Simultaneous correction of the different anomalies observed in the congenital convex foot was achieved in this series. The anatomic and functional results were satisfactory. We recommend avoiding overly extensive release in order to decrease the risk of talar and navicular necrosis. It is also important to check the reduction radiographically during the operation. Patients should use an orthesis for several months postoperatively to avoid recurrence.

[Pterygium: surgical treatment]. / Ptérygion: traitement chirurgical.

PURPOSE: The surgical management of pterygium is often complicated by recurrence of disease. The goal of this study was to compare three different surgical techniques used for the treatment of pterygium. METHOD: We propose a prospective and partly retrospective study on 167 cases of pterygium 151 were primary and 16 were recurrent, treated between 1 January, 1995 and 30 June, 1998. The surgical treatment used of 3 different techniques: pterygium excision for 111 eyes, pterygium excision with conjunctival autograft for 29 eyes, pterygium excision with application of mitomycin C for 27 eyes. RESULTS: Immediate results for the three kinds of treatment were good. No serious complications were noted. Long-term results show a recurrence rate of 10.3% for conjunctival autograft, 11.1% for mitomycin C application, while the pterygium excision alone had a recurrence rate of 55.9%. CONCLUSION: This study demonstrated that conjunctival autografting and the application of mitomycin C are safe surgical techniques that reduce the probability of recurrence after surgery for pterygium. They can be recommended for young people and patients exposed to sun. Mitomycin therapy is the most appropriate treatment for these cases, because of its simplicity, lower lost and the relative lack of complication.

[Effect of scleral indentation on the corneal topography and the axial length after retinal detachment surgery. A prospective study in 30 cases]. / Influence de l'indentation sclérale sur la topographie cornéenne et la longueur axiale dans la chirurgie du décollement rétinien. Etude prospective à oriois de 30 yeux.

INTRODUCTION: Scleral indentation is an essential time in conventional retinal detachment surgery. It enables re-establishing retinal contact and to counterbalance vitreal tractions. It can be circular, segmental or radial. Silicone materials are often used. MATERIALS: In a prospective study, we followed up 30 eyes of patients who underwent retinal detachment surgery. We analyzed changes in corneal surface using differential map of the corneal (induced astigmatism, meridian axial deviation) and change in the axial length of the globe. RESULTS AND DISCUSSION: Follow-up examination showed corneal astigmatism: 2.62 diopter (D) at one week, 2.37D at one month and 1.80D at 3 months. Corneal axis meridians changed: 25 degrees at one week and 18.6 degrees at 2 months. Axial length was also modified. We observed a lengthening: 1.7mm during the first week which remained unchanged at 1.63 after 2 and 3 months. These changes were studied according to the different techniques used in our study and were compared with results reported in the literature. CONCLUSION: We think that conventional retinal detachment surgery causes modifications in refractis (induced astigmatism and axial lengthening).
