[Leishmaniasis and human immunodeficiency virus: an emerging co-infection?].

Although not considered as indicative of AIDS, leishmaniasis presents a number of epidemiologic and clinical features that promote opportunistic infection in HIV patients. Accurate assessment of the incidence of this type of co-infection is difficult due to underestimation in endemic areas such as Africa and Asia. In these areas the WHO estimates that 2 to 9 p. 100 of HIV patients will develop leishmaniasis/HIV co-infection which could become a major concern. The characteristics of this co-infection have been documented. It is observed in adults between 20 and 40 years of age with a strong male sex bias. The visceral form is most frequent. Manifestations are similar to those observed in immunocompetent subjects but with the possibility of asymptomatic and low-grade forms (10 p. 100) and unusual locations suggesting multiorgan spreading in absence of host immune response. In addition to the time-tested standard procedures for diagnosis of parasitic disease, new serologic tests and genomic amplification are now available. Pentavalent antimonials have long been considered as the treatment of choice but they are not always effective and can have untoward effects. Amphotericine B especially in the liposomal form is a good alternative. The particularly high incidence of recurrence suggests that follow-up may be indicated but the modalities of prophylaxis have yet to be defined.

[Polyarthralgia disclosing hyperthyroidism. Two case reports].

BACKGROUND: We report two cases of rheumatism associated with hyperthyroidism. In both cases, arthralgia totally regressed after thyroid treatment. CASE REPORTS: Two 79-year-old and 59-year-old women developed manifestations of polymyalgia rheumatica and psoriasis arthritis respectively. Corticosteroid therapy was ineffective and followed by manifestations of hyperthyroidism. The first patient was treated with carbimazole and the second with thyroidectomy. Once the hyperthyroidism was controlled, both patients experienced a dramatically rapid cure of their arthralgias. DISCUSSION: Scalpulo-humeral periarthritis is the main articular complication of hyperthyroidism. True manifestations of "thyrotoxicosis rheumatism" are unusual and may be linked with a direct toxicity of the thyroid hormones on joint cartilage or with an autoimmune manifestation of hyperthyroidism.

[Superior vena cava syndromes of benign etiology].

Superior vena cava syndromes are uncommon and usually caused by malignant diseases. In about 20% of the cases however, the cause is benign. Besides chronic mediastinitis, a growing number of cases are reported of thrombosis resulting from endovenous devices (central catheters, pacemaker leads...). Onset is often slow and insidious, good tolerance in the early stages being explained by the development of an effective collateral circulation. Bibrachial phlebography is still the reference exploration, but computed tomography and magnetic resonance imaging are contributive to diagnosis. Symptoms usually regress after medical treatment, sometimes requiring thrombolysis, however, in 10% of the patients, major functional impairment may require bypass surgery (autologous graft or endoprosthesis) or transluminal angioplasty. There is still some debate as to the precise indications for each method, but angioplasty, used recently, appears to be the most interesting technique for a disease in which prognosis is almost always favorable.

[Bone marrow aplasia related to ticlopidine].

The authors report two cases of bone marrow aplasia observed 2 months after initiation of a treatment with ticlopidine. The outcome was favorable after discontinuation of therapy. The frequency of this severe drug-induced complication seems to have been underestimated. The absolute necessity of a careful haematological survey during the first 3 months of therapy is pointed out.

[Panniculitis-fasciitis syndrome disclosing systemic erythematous lupus].

INTRODUCTION: Panniculitis is a common manifestation of lupus, but is rarely the first manifestation in systemic lupus erythematosus. We report a case associated with fasciitis. CASE REPORT: A 67-year-old man was hospitalized for fever, pleuropericarditis, subcutaneous diffuse infiltration of the two thighs and the abdomen due to panniculitis and lupic fasciitis. Antiphospholipid antibody test was positive. There was non antiphospholipid syndrome. COMMENTS: Panniculitis can occur simultaneously or a few months or years before systemic lupus erythematosus. An association with fasciitis should be entertained whenever the cutaneous involvement is extensive and firm. In such a situation, deep biopsies are indicated. Observations of further cases will help identify the role of general steroid therapy in fasciitis-panniculitis and systemic lupus erythematosus.
