[A case of papillitis revealing primary syphilis].

OBJECTIVE: Syphilitic ocular manifestations are polymorphous and usually occur during the secondary or tertiary stage of syphilis. We report a case of primary syphilis revealed by papillitis. DESIGN: A 22 year old man presented with blurred vision in the left eye and decreased visual acuity. Fundus examination and fluorescein angiography revealed a papilledema in the left eye and chorioretinitis in the right one. Clinical examination revealed a painless ulceration of the chin. Blood tests were positive for syphilis (positive reaction to the VDRL test and TPHA titer at 1/640) but negative for HIV. After penicillin therapy, the ocular manifestations resolved. RESULTS: Papillitis is a relatively rare ocular manifestation of syphilis. Our case is original because papillitis was the presenting manifestation of the disease and that it was concomitant with the primary chancre. CONCLUSION: Systematic screening for syphilis should be performed in unexplained ocular inflammation.

[Behçet's disease in Tunisia. Clinical study of 519 cases].

PURPOSE: To describe clinical characteristics of Behçet's disease in Tunisia. METHODS: It's a retrospective and multicentric study conducted by the Tunisian society of internal medicine. Inclusion criteria were those of the international study group. Were also included patients without international study group criteria but with at least one manifestation among arthritis, venous thrombosis or neurological manifestation with oral and genital ulceration or oral ulceration and skin lesions. RESULTS: Five hundred and nineteen patients were included. 87.5% of them fulfilled the international criteria. The male to female ratio was 2,7. The mean age was 28.7+/-9.3 years at onset and 32.7+/-9.2 years at diagnosis. The incidence of each manifestations was as follows: oral ulcers: 100%, genital ulcers: 87.5%, pseudo-folliculitis: 67.6%, erythema nodosum: 17.5%, positive pathergy test: 51%, joint involvement: 55%, uveitis: 32.2%, vein thrombosis: 24.9%, arterial aneurysms: 3.9%, neurological involvement: 11.6%. The frequency of HLA B51 antigen was 35% among the 187 patients tested. There was no difference in the manifestations of the disease between patients having B51 and those lacking it. Venous thrombosis (29.8 vs 11.4%), arterial involvement (4.4 vs 1.4%) and uveitis (37.5 vs 17,9%) were significantly more frequent in men whereas erythema nodosum (22.9% vs 15.6%) and joint involvement (70,7 vs 49.9%) more frequent in women. The mean follow up was 6,1+/-5.7 years. Mortality rate was 2.3% in our series. CONCLUSION: Our study confirms the androtropism of the disease in Mediterranean and Middle east countries. Positive pathergy test and venous thrombosis were more frequent in our study, like those from Mediterranean region. Whereas, ocular and neurological involvement were quite less frequent in our series.

[Abnormality of hepatic perfusion secondary to superior vena cava obstruction: three case reports].

The aim of this study was to evaluate the altered flow dynamics of liver perfusion that can be observed during superior vena cava obstruction. Through the description of three case reports of patients with SVC obstruction, the authors discuss the different collateral pathways used that result in systemic portal venous shunting creating this altered flow dynamics and their appearance in computed tomography.

[Takayasu's arteritis associated with acute myeloblastic leukemia].

INTRODUCTION: We present one patient with acute myeloblastic leukemia diagnosed two months after the onset of Takayasu's arteritis. EXEGESIS: A 21-year old woman with a previous history of erythema nodosum and episcleritis was admitted for a left cervical mass. Diagnostic imaging showed an aneurism of the left extracranial internal carotid and a stenosis of the left subclavian artery. Histological findings of the carotid aneurism revealed a granulomatous giant cell arteritis consistent with Takayasu's arteritis. Two weeks after, she was discharged, elevated white cell count (440.000/mm3 ) was disclosed. A bone marrow aspirate documented an acute myeloid leukemia. The patient died of intracerebral hemorrhage. CONCLUSION: Leucocytoclastic vasculitis and polyarteritis nodosa occur in acute myeloid leukemia, but the association with Takayasu's arteritis is new. In our knowledge, only two documented cases of Takayasu's arteritis in association with acute myeloblastic leukemia have been published.

[Vertebral and spinal cord hydatidosis: contribution of imaging].

The authors report the case of a vertebromedullary hydatidosis revealed by medullar compression in a 40-year-old male patient. Magnetic resonance imaging showed lesions of the seventh and eighth dorsal vertebras, cystic lesions in the epidural space and in the perivertebral soft tissues. Surgical excision lead to clinical cure. Vertebromedullary hydatidosis is rare and severe. Modern techniques of imaging are very helpful for the diagnosis and the follow-up of patients after treatment.

[Pachydermoperiostosis: a report of two cases].

Pachydermoperiostosis or primary hypertrophic osteoarthropathy is a benign genetically determined disease, manifested by finger clubbing, hypertrophic skin changes and periosteal bone formation. It is rarely reported and was for a long time misdiagnosed and confused with secondary hypertrophic osteoarthropathy. We present the imaging features in two cases and review the literature.

[Eagle syndrome: case report].

Eagle's syndrome, also known as elongated styloid process, is an entity that may be the source of craniofacial and cervical pain. It is frequently reported but is probably more common than generally considered. The symptoms related to Eagle's syndrome can be confused with those attributed to a wide variety of Oropharyngeal and Maxillofacial diseases. The paucity of information in the radiologic literature prompted this report.

[Activated protein C resistance in Behçet disease].

Behçet's disease is a systemic condition of unknown cause characterized in 20 to 40% of cases by venous and/or arterial thrombosis that is not fully explained by the hemostasis disorders reported in the literature. The present study investigated resistance to activated protein C in 65 Behçet's disease patients, 75 normal subjects, and 70 patients with a history of isolated thrombosis. The test used involved predilution in factor V-deficient plasma. Activated protein C resistance was found in six Behçet's disease patients (9.2%), eight normal subjects (10.6%), and 21 patients with isolated thrombosis (30%). Of the 26 Behçet's disease patients (40%) with a history of thrombosis, only one had activated protein C resistance. Activated protein C resistance does not explain the increased risk of thrombosis in Behçet's disease patients.

[Wegener's granulomatosis and pregnancy. A case].

Pregnancy concomitant with Wegener's granulomatosis is extremely rare: so far, only four cases have been published. The authors report a fifth case where the disease appeared during the post-partum period, a situation which has already been noted in two of the published cases. Interruption of a subsequent pregnancy was followed by a flare-up of the disease resulting in the patient's death. This suggests that post-partum and post-abortum are probably instrumental in the onset and deterioration of Wegener's granulomatosis. The two patients previously reported who received immunosuppressants combined with corticosteroids had no flare-up after delivery. It seems permissible to prescribe such a therapeutic combination before and after delivery or abortion, especially since the fear of foetal toxicity from these drugs seems to be exaggerated.
