[Central nervous tuberculosis in patients non-VIH: seven case reports].

PURPOSE: Tuberculosis involving the central nervous system (CNS) is rarely observed in non immuno-compromised hosts. We report herin the various clinical, biological and radiological manifestations observed in 7 patients with CNS tuberculosis. METHODS: Clinical and biological records of 7 patients with CNS tuberculosis were retrospectively studied. All patients had encephalic CT-scan and MRI in the course of the disease. RESULTS: 5 women and 2 men with a mean age of 38.4 years initially initially presented with headache (n = 6), fever (n = 5), meningeal irritation (n = 3), localizing neurological signs (n = 1). Lumbar punction revealed lymphocytic meningitis (n = 6/7). Mycobacterium tuberculosis or bovis was isolated in 3 patients only. Cerebral tomodensitography or magnetic resonance imaging were initially normal in most of cases (n = 4/7), but discovered in the course of disease basilar meningitis (n = 6), hydrocephalus (n = 6), abcess or tuberculoma (n = 4). In all the patients, initiation of the treatment was complicated by clinical and/or biological deterioration, called paradoxal reaction, leading in all cases to glucocorticoid adjunction, with various final results. Indeed, 4 patients developed neurological sequelae. No patient died. CONCLUSION: CNS tuberculosis is a rare disease in non immunocompromised patients whose diagnostic may be difficult due to the absence of specific clinical symptoms, negative initial radiological examination, as well as delayed and often negative bacterial isolation. Paradoxal reaction appeared to be frequent despite specific antibiotherapy and underlines the beneficial effects of addictive corticosteroids.

CIAS1 mutation in a patient with overlap between Muckle-Wells and chronic infantile neurological cutaneous and articular syndromes.

The Muckle-Wells syndrome is a rare autosomal dominant disorder belonging to the group of hereditary fever syndromes. The chronic infantile neurological cutaneous and articular (CINCA) syndrome is a systemic inflammatory disorder of unknown etiology with neonatal onset. They are considered as two different entities. We report the case of a 36-year-old man suffering since birth from a nonpruritic generalized urticaria, with inflammatory flares, joint manifestations and progressive deafness requiring a bilateral hearing aid. An initial diagnosis of Muckle-Wells syndrome was made. However, the patient had an unusual clinical presentation with slightly dysmorphic facial appearance, clubbing of the fingers, mild mental retardation and papilledema. After a genetic advice, a diagnosis of CINCA syndrome was made. Search for mutations in the CIAS1 gene revealed a new mutation in a heterozygous state. This case report really raises the question of a link between these two inflammatory diseases. Further studies are needed to confirm the involvement of mutations of the CIAS1 gene in CINCA syndrome.

[Heyde syndrome].

OBJECTIVE: Heyde's syndrome associates aortic stenosis and digestive hemorrhage secondary to intestinal angiodysplasia. OBSERVATION: A 61 year-old man presented with anemia due to martial deficiency and melena, the endoscopic examination of which was negative. The existence of a tight aortic stenosis, suspected on auscultation, suggested the diagnosis of Heyde's syndrome. Angiodysplasia is revealed during oriented enteroscopy. Following valve replacement, the need for transfusion disappeared, together with the anemia. DISCUSSION: Although some epidemiological studies deny the existence of this syndrome, the observation of authentic cases of resolution of digestive bleeding following surgical replacement of an aortic valve, such as ours, is an argument in favor of the reality of Heyde's syndrome.

[Retrospective study of 55 patients with circulating blood T gama/delta lymphocytosis].

PURPOSE: Gamma/delta T lymphocytes constitute a singular population due to their particular antigenic recognition and their localization inside the epithelium. Their functions are complementary to those of the alpha/beta T-cells and they are involved in the defense and regulation of the immune system. Their role in human diseases is not very well understood and the aim of our study was to analyze a population of patients with a peripheral gamma/delta T-cell lymphocytosis. METHODS: The study included 55 patients, recruited from 1997 to 2000, with a peripheral gamma/delta T lymphocytosis (defined by a proportion of gamma/delta T-cells of over 10% of total peripheral T lymphocytes). Analysis of the lymphocyte population was obtained by cytometry after peripheral blood sampling. RESULTS: Three main groups of diseases were observed: infectious diseases (viral infections and tuberculosis), inflammatory diseases (sarcoidosis and autoimmune diseases) and blood diseases (monoclonal gammopathies and hemopathies). Persistence of gamma/delta T lymphocytosis was dependent on the underlying disease (transitional when associated with an infectious disease and lasting when associated with sarcoidosis). The rest of the immunophenotyping analysis was usually normal. CONCLUSION: Our results confirm the data published in the literature concerning the role of the gamma/delta T lymphocytes in infectious, inflammatory and autoimmune diseases and neoplasias. These data are in agreement with the cytotoxic and regular functions of these lymphocytes.

[Camptocormia: a sign of axial myopathy. Report of 7 cases].

PURPOSE: Camptocormia or progressive lumbar kyphosis is an anterior bend of the trunk. It appears in orthostatism or while walking and is reducible in the decubitus position. It concerns patients older than 60 years of age. It is due to a fatty degeneration of the paravertebral muscles, although the physiopathology remains unclear. METHODS: We report seven cases of camptocormia revealing authentic myopathies. RESULTS: Our observations concern five women and two men of 55 to 72 years of age. All patients present lumbar kyphosis and had a fatty involution of the paraspinal muscles on the muscular MRI. Four patients fulfilled the Bohan and Peter criteria of polymyositis and dermatomyositis. In the other cases paravertebral muscular biopsies led to the diagnosis of a congenital myopathy, a mitochondrial myopathy and an amyloid myopathy. Four patients received a corticosteroid-immunoglobulins or cyclosporin regimen. An improvement in the camptocormia was observed in three cases. In the other cases the treatment consisted of chemotherapy on account of severe nephrotic syndrome, a coenzyme-Q treatment for the patient with mitochondrial myopathy and only physiotherapy in the case of congenital myopathy, but without positive effect on camptocormia. CONCLUSION: Camptocormia appears as a muscular symptom that may reveal an axial myopathy due to multiple and varied pathologies. Thus, the discovery of camptocormia requires an aetiological investigation in order to propose an adequate treatment, which should be associated with physiotherapy.

Sarcoidosis preceding chronic myelomonocytic leukemia. Report of two cases.

We report 2 patients who had sarcoidosis with skin involvement associated with bilateral anterior uveitis. During the follow-up, they developed chronic myelomonocytic leukemia. This association is of particular interest as sarcoidosis and chronic myelomonocytic leukemia may be considered as disorders of a common monocyte-macrophage cell lineage.

Epiglottis involvement in a visceral leishmaniasis.

The visceral form of leishmaniasis caused by Leishmania infantum is frequently observed in Mediterranean countries, however otorhinolaryngeal involvement has only rarely been reported in the literature. We report here the case of a 23-year-old Cameroon man, resident in France since 1991, and presenting with recurrent epistaxis and an epiglottis tumoral lesion. The visceral form of leishmaniasis with hepatosplenomegaly and pancytopenia was diagnosed. Culture of the epiglottal lesion revealed L. infantum. Serological test for human immunodeficiency virus was negative and the patient was not on immunosuppressive drugs. Dramatic improvement was observed with antimony.

[Stevens-Johnson syndrome followed by Gougerot-Sjögren syndrome].

BACKGROUND: Sicca syndrome after Stevens-Johnson syndrome is classically described. However, to our knowledge, authentic Sjögren's syndrome following epidermal necrolysis has not been described previously. CASE REPORT: A 36-year-old woman with Steven-Johnson syndrome developed transient hepatitis and a persistent sicca syndrome. Fourteen years later an authentic Sjögren's syndrome was identified with presence of antinuclear and anti-SSA antibodies and lymphocytes infiltration of the accessory salivary glands, i.e. grade IV disease in the Chisholm classification. DISCUSSION: The initial mucosal destruction observed in our patients may have laid the ground for Sjögren's syndrome via abnormal antigen presentation in a predisposed dysimmune context.

A case of polymyositis with anti-histidyl-t-RNA synthetase (Jo-1) antibody syndrome following extensive vinyl chloride exposure.

Occupational exposure to vinyl chloride monomers is known to induce Raynaud's phenomenon, periportal fibrosis, liver angiosarcoma and scleroderma-like syndrome. We report the first case of occupational polymyositis in a 58-year-old man exposed to vinyl chloride. A dysimmune process was strongly suspected as having induced vinyl chloride disease. Our patient had an anti-histidyl-t-RNA-synthetase (Jo1) antibody, which has never to our knowledge been reported in this occupational disease.

[Psychological and behavioral disorders with good outcome in neurosarcoidosis].

INTRODUCTION: Neurological involvement is observed in 5% of cases of sarcoidosis and includes impairment of the central nervous system, the meninges, and the cranial and peripheral nerves. Besides neurological defects, cognitive impairment may be encountered ranging from isolated memory defect to dementia. EXEGESIS: We report a case of neurosarcoidosis occurring in a 40-year-old woman, a native of Reunion Island, with initial meningeal and hypophyseal involvement. Three years later, while treated with low dose prednisolone and methotrexate, she presented a paranoid state associated with cognitive impairment of frontal type and severe behavioral disturbances. After 2 years of high dose steroid treatment associated with hydroxychloroquine, her behavioral status improved, allowing social and familial reinsertion. CONCLUSION: In our observation, sarcoidosis was revealed through a central neurological impairment, with chronic meningitis, facial nerve palsy, and, finally, through psychiatric symptoms and severe behavioral disturbances. A slow favorable outcome was obtained using high dose methylprednisolone and hydroxychloroquine with total regression of behavioral disturbances but with persisting cognitive alteration.

[Acute transitory intrafamilial erythroblastopenia and hereditary spherocytosis: role of parvovirus B19].

INTRODUCTION: Acute parvovirus B19 infection induces a transient inhibition of erythroid cell formation, which may induce an erythroblastopenia crisis in patients suffering from chronic hemolytic anemia. EXEGESIS: We report here an exceptional observation of acute erythroblastopenia crisis with good outcome, occurring at the same time in a mother and her son, both suffering from hereditary spherocytosis. Diagnosis of parvovirus infection is based on detection of serum parvovirus B19-specific immunoglobulin M antibodies in the mother and her son and by the positivity of parvovirus B19 DNA detected by PCR in serum in the mother. Outcome was good, with the end of the erythroblastopenia crisis obtained 7 to 10 days later, but requiring blood transfusion in the mother. CONCLUSION: Our observation is a reminder that the contagiosity of parvovirus B19 is high in household contacts and that protection of family members should rapidly be considered in hereditary spherocytosis.
