[Complete auriculoventricular block during chloroquine treatment].

INTRODUCTION: The cardiac toxicity of antimalarial agents is rare, it includes conduction disorders which can be complicated by third atrioventricular block and hypertrophic cardiomyopathy. We report two observations of patients who presented a complete heart block after several years of treatment by chloroquine. CASE REPORT: Two patients followed for rheumatoid polyarthritis, treated by antimalarial agents for average 12 years and corticotherapy, presented a syncopal complete heart block which required an implantation of a pace maker. After having eliminated all the other underlying causes for complete heart block, the antimalarial agents were accused and were stopped. The clinical evolution after interruption of the treatment was favorable. CONCLUSION: Our observations illustrate rare cardiac side effects observed in our two patients after long-term treatment by antimalarial agents. The diagnosis of antimalarial agents responsibility was retained on clinical and biological arguments after having eliminated the other causes. The insidious character of these complications imposes vigilance during the use of long-term treatment by antimalarial agents.

[Leukemia revealed by polyarthritis].

INTRODUCTION: Ostéoarticular manifestation whose reveal leukaemia in 4% of the cases, regress completely with haematological remission. EXEGESIS: We report two observations of leukaemia revealed by polyarthritis. A 22-year-old woman has presented a polyarthritis 8 months before de diagnosis of acute leukaemia. A 34 years old men, has presented one month before admission an acute polyarthritis revealing chronic myeloid leukaemia. CONCLUSION: Polyarthritis may reveal an acute or chronic leukaemia. Systematic blood analysis can make a difference in diagnosis of recent polyarthritis.

[Bilateral uveitis in relapsing polychondritis. A case report].

We report a rare ocular manifestation of relapsing polychondritis. A 28-year-old woman presented with a 5-year history of relapsing polychondritis with chondritis of the nose, ears and tracheobronchial system. The ocular symptoms were bilateral uveitis with macular involvement and papillaedema. Ocular manifestations of relapsing polychondritis occur in 60% of patients. Uveitis is a rare symptom, sometimes severe, which can lead to blindness. This case report with a literature review sheds light on the features of this disease.

[Cardiac manifestations of idiopathic hypereosinophilic syndrome].

BACKGROUND: The aim of our study is to describe the more common cardiac manifestations of idiopathic hypereosinophilic syndrome representing the major cause of mortality. MAIN POINTS: Current therapy consists of corticosteroid, hydroxyurea and interferon alpha. Recent publications confirm the activity of imatinib mesylate, a selective tyrosine kinase inhibitor, in patients with idiopathic hypereosinophilic syndrome. In cases with marked valvular compromise or with endomyocardial thrombosis or fibrosis, cardiac surgery can provide substantial benefits. PERSPECTIVES: A better understanding of the pathophysiology of this syndrome could lead to the development of new therapeutic agents.

Behçet's disease in Moroccan children: a report of 12 cases.

We report 12 cases of Behçet's disease (BD) in children. The mean age of symptom onset was 12.4 years. Four patients (33.3%) had a past familial history of BD. Clinical manifestations were: oral aphtosis (n = 12), genital aphtosis (n = 9), ocular involvement (n = 9), neuro-Behçet (n = 6), venous thrombosis (n = 4), articular involvement (n = 3), and entero-Behçet (n = 1). All patients but one were initially treated with steroids; three cases with ocular involvement were treated with chlorambucil; and three other cases of neuro-Behçet were treated with cyclophosphamide. After a mean follow-up of 4 years, four patients with neurological involvement developed steroid-dependence with recurrence of symptoms. Four patients had optic atrophy with blindness.

Increase in bone mineral density of patients with spondyloarthropathy treated with anti-tumour necrosis factor alpha.

OBJECTIVE: To determine the changes in bone mineral density (BMD) in patients with spondyloarthropathy (SpA) treated with infliximab. PATIENTS AND METHODS: 29 patients (six women; 23 men) aged 22-68 years, with persistently active SpA despite a high dose of non-steroidal anti-inflammatory drug and/or treatment with methotrexate or sulfasalazine, were studied. Median duration of disease was 13 years (range 3-30). Twenty five patients were treated with 5 mg/kg and four with 3 mg/kg of infliximab at weeks 0, 2, 6 and then received either no infusion (n=3), or additional infusion of infliximab every other month (n=6), and the remainder received one infusion only in the case of a relapse. Lumbar and femoral BMD was measured by dual energy x ray absorptiometry at baseline and six months later. Serum osteocalcin and urinary deoxypyridinoline were measured in 19 patients at weeks 0, 2, 24, and in 13 patients at all visits. RESULTS: In six months there was a significant increase in BMD at the spine (3.6%, p=0.001), total hip (2.2%, p=0.0012), and trochanter (2.3%, p=0.0012). A trend for increase (1.1%) was observed at the femoral neck. There was an increase in osteocalcin between baseline and week 6 (third infusion)-median 1.45 micro g/l (p=0.013). No change in marker of bone resorption was observed at the same time. There was no change in biochemical markers between baseline and final visits. There was a trend for a correlation between the decrease at six months in erythrocyte sedimentation rate, and lumbar spine BMD change (r(s)=-0.35, p=0.06). CONCLUSION: These data suggest that a benefit of anti-tumour necrosis factor alpha therapy on BMD in patients with SpA may be through an uncoupling effect on bone cells.

[Childhood Behçet's disease: clinical and evolutive aspects. About 13 cases].

INTRODUCTION: Behçet's disease is a systemic vasculitis which rarely occurs in childhood. The aim of this study was to evaluate clinical characteristics and outcome of Behçet's disease in Moroccan children. MATERIAL AND METHODS: A retrospective study of 13 cases of children, 10 males and 3 females with Behçet's disease followed up between 1990 and 1998. The diagnosis of Behçet's disease was based on the criteria of the international study group for Behçet's disease. All patients were studied by a complete clinical, ophthalmological and laboratory staging and treated with appropriate therapy. RESULTS: The mean age at diagnosis of Behçet's disease was 13.9 years. Familial forms were found in 30.7% of cases. Oral aphtae were noted in all cases while genital ulcers were present in 76% of cases. Cutaneous lesions were found in only 1 case and 53.8% of children had a pathergy test. Articular involvement was found in 30.7%, neurological features in 46% and vascular manifestations in 38.4%. Only one case of intestinal involvement was noted. Ocular features (76%) were bilateral in all cases and were dominated by panuveitis complicated by macular edema ant retinal vasculitis. CONCLUSION: Behçet's disease seems to have particular characteristics in childhood. Familial forms, articular and digestive manifestations appear to be more frequent in early stages of Behçet's disease in children. Neurological and vascular involvement with panuveitis seems more frequent in the older children.

Atlantoaxial tuberculosis: three cases.

Tuberculosis of the craniocervical junction (CCJ) is exceedingly rare but carries a risk of compression of the medulla oblongata and upper spinal cord. Three cases among 63 patients with spinal tuberculosis are reported. Mean age was 51 years (range, 20-69) and mean time to diagnosis was 4.6 months (range, 1-8). Although atlantoaxial dislocation was a consistent feature, none of the patients had neurological deficits. Computed tomography of the CCJ disclosed a suggestive pattern combining osteolysis and an abscess anterior to the spine. The diagnosis was confirmed by microbiological studies in two cases and histology in one. The outcome was favorable after antituberculous therapy, immobilization of the neck, and surgical fusion. Although tuberculosis remains common in developing countries, involvement of the CCJ is rare. Tuberculosis of the CCJ carries a risk of instability and severe neuraxis compression. Consequently, early diagnosis and treatment are of the utmost importance.

Erosive polyarthritis in Crohn's disease. Report of a case.

Erosive polyarthritis in Crohn's disease is rare and raises diagnostic and pathophysiological problems. A case with destructive lesions of the shoulders and hips is reported in a 43-year-old woman with a 26-year history of Crohn's disease. Ankylosis of the spine and hips, motion range limitation of the shoulders and wrists, and boutonnière deformity of the third finger of the right hand were present. Tests were negative for rheumatoid factor and the HLA-B27 antigen. Plain radiographs showed a triple rail pattern at the spine; synostosis of the hips; and destructive lesions of the shoulders, wrists, tarsal bones, and third proximal interphalangeal joint of the right hand. Glucocorticoid therapy was effective in suppressing the bowel symptom flares but only partially improved the joint symptoms, whose treatment relied mainly on nonsteroidal antiinflammatory agents and rehabilitation therapy. Erosive arthritis in Crohn's disease is frequently monoarticular, with the hip being the most common target. It can complicate a spondylarthropathy or reveal granulomatous synovitis. Polyarticular forms pose difficult diagnostic and therapeutic challenges and add to the disability caused by the bowel disease. The potential role of genetic factors remains to be studied.

[Pubic tuberculous osteo-arthritis. Apropos of 2 cases].

OBJECTIVE: The authors report an exceptional site of tuberculous osteo-articular infection which must be diagnosed before the destructive stage. OBSERVATIONS: Case 1 : a 21 years old woman presented an inflammatory pubic pain after a trauma with weight loss of 4 kgs in 3 weeks. She presented also 2 satellite inguinal nodes. Erythrocyte sedimentation rate (ESR) was elevated, X-rays showed an important osteolysis of the left ischio-pubic rami, tuberculous skin test (TST) was positive, mycobacterium tuberculosis (MT) could not be found neither in sputtum nor in urine but the node biopsy showed the specific features of tuberculosis. Evolution under a 6 months antibiotic treatment was good. Case 2 : a 19 years old woman, with history of tuberculous contagion, presented in April 1996 cervical nodes and a month later inflammatory pubic and knee pain with weight loss and vesperal sudation. ESR was elevated, TST was phlyctenular, MT searching and HIV serology were negative. X rays showed irregular osteolysis of the pubic symphysis. Scintigraphy showed an increased fixation of pubis and left knee. Cervical nodes biopsy diagnosed tuberculosis. Evolution was good under a 6 months antibiotic treatment. DISCUSSION: Many factors can favorize the development of a pubic tuberculosis and are similar for all forms of tuberculous osteo-articular infection (trauma and contagion in our cases). Radiological features, characterized by a slow evolution, are note specific. Diagnostic confirmation must be bacteriologic or pathologic, and if possible far from the pubic foci. Any traumatic medical procedure has to be avoided because of painful outcome and local risk. Evolution under specific treatment, even of short course (6 months), is sufficient for a good outcome. CONCLUSION: One must think to pubic tuberculous osteo-arthritis in any pubic pain even if it is post-traumatic especially, in endemic countries of tuberculosis.

[Evaluation of 17-beta-hydroxysteroid dehydrogenase activity as a marker of the hormone dependence of breast cancers].

Intratumoral activity of the enzyme 17 beta-hydroxysteroid dehydrogenase (17 beta-HSD) was measured in 55 patients with breast cancer (17 pre- and 38 post-menopausal) before and/or after 8 days of a progestin treatment (lynestrenol 10 mg/day). In 12 patients the 17 beta-HSD ability to be stimulated was compared to estradiol and progesterone receptor (ER and PR) levels. In premenopausal patients 17 beta-HSD was higher when tumorectomy was performed in the luteal phase than in the follicular phase. In post-menopausal patients, 17 beta-HSD is higher after progestin treatment. However 17 beta-HSD stimulation by lynestrenol depends on receptor levels. It is most after markedly stimulated in ER+ PR+ tumors. It remains low in ER- PR- tumors. In conclusion, intratumoral measurement of the progesterone dependent enzyme (17 beta-HSD) in breast cancer after progestin treatment provides a fine and reliable index of the presence and functional character of PR and hormone dependence of the tumor.

[Results of oocyte donation in women with different indications, ages and therapeutic strategies].

PURPOSE: Compare the effectiveness of oocyte donation for various indications, ages and treatments. METHODS: Retrospective analysis of 319 transfers for 184 couples (243 with fresh embryos and 76 with frozen embryos). Transfers are divided into: -7 groups according to indication: premature ovarian failure (POF) with normal caryotype n = 122, surgical POF n = 26, postchemotherapy and postradiation therapy POF n = 23, genetic disease carrier n = 11, IVF failure n = 69, primary amenorrhea n = 58, POF with abnormal caryotype n = 10. -2 groups according to the recipient's age (Group I < or = 40 years, Group II > 40 years); -3 groups according to the dose and the mode of administration of the treatment. Oocytes were donated by volunteer donors of less than 38 years having at last one child. RESULT: According to the recipient's age 31.3% clinical pregnancies (CP) and 24.2% ongoing pregnancies (OP) for group I, versus 19.4% CP and 11.9% OP for group II. The results according to the indication were similar except for postchemotherapy and postradiation therapy POF for which the rate of CP as well as the rate of OP were particularly low. For the treatment groups there is a significant reduction of CP and OP as the treatment dose increases. CONCLUSION: The recipient's age plays an important role for the development of pregnancy and this shows that apparently uterine ageing also plays an undeniable role for the decline of female fertility. Increasing doses of estradiol reduces the rate of CP and OP. Postchemotherapy and postradition therapy POF has much lower results than other indications.
