[Pregnancy and systemic scleroderma. A case report].

The systemic scleroderma is an auto-immune affection characterised by diffuse lesions of the connective tissues with inflammatory predominance. As less frequent as this association with pregnancy, it usually occurs to the woman at the end of genital life activity. The obstetrical past history of a G5P2 of 40 years old affected with systemic scleroderma, is marked by four tardive abortions and two premature deliveries. The evolution of the disease was progressively unfavourable with visceral, digestive and pulmonary blows them sclerodermatomyositis. A review of literature reveals the interactions between this affection and pregnancy. The aggravation of the disease during pregnancy is possible: nephopatic scleroderma is then the most frequent complication. The gynaecological and obstetrical consequences are sterility, habitual abortions, intra-uterine growth retardation, intra-uterine foetal death, premature delivery and expulsion difficulties. The infant prognostic is specially related to the risk prematurity. The corticotherapy is the only acceptable treatment during pregnancy.

Crossover study of thalidomide vs placebo in Jessner's lymphocytic infiltration of the skin.

BACKGROUND AND DESIGN: An effective therapy is still unavailable for Jessner-Kanof lymphocytic infiltration of the skin. Thalidomide's efficacy was suggested in an open study. Twenty-eight patients were randomly assigned to receive thalidomide (100 mg/d) or placebo over a period of 2 months and were then switched to the other treatment. RESULTS: After the first period, 11 of 13 patients treated with thalidomide were in complete remission (CR), and there were two failures. There was no CR in the patients who received placebo (chi y2 = 17.5; P < .0001). After the second period, nine of 14 patients who had received thalidomide were in CR. Eleven of the 13 patients who had received thalidomide during the first period were given placebo (two were unavailable for follow-up). Ten of them were in CR: four were still free of lesions at the end of the second period, and six experienced a relapse of their lesions after a mean duration of 26 +/- 10 (SD) days. A total of 25 patients participated in the two study periods; CR was observed in 19 (76%) after thalidomide therapy and in four (16%) after treatment with placebo (chi y2 = 11.1; P < .001). Of 27 patients who received thalidomide, 16 (59%) were in CR after 1 month and 20 (74%) were in CR after 2 months. Two patients treated with thalidomide experienced neurologic changes that were not consistent with typical thalidomide-induced neuropathy. CONCLUSIONS: A therapeutic regimen of thalidomide administered at a dosage of 100 mg/d for 2 months is able to suppress the clinical symptoms of Jessner-Kanof lymphocytic infiltration of the skin. The long-term risk-benefit has still to be evaluated.

[Cutaneous rhabdomyosarcoma].

OBJECTIVE: The occurrence of a rare alveolar rhabdomyosarcoma in a 16-year old girl seems worth of a case report. OBSERVATION: A large multinodular tumor developed on the buttocks and the external genitalia; systemic symptoms and metastases of lymph nodes and skin occurred very soon and the disease had a lethal outcome within 16 months. A temporary regression was observed after polychemotherapy with daunorubicine, vincritine and 5-fluoro-uracile. COMMENTS: In children the rhabdomyosarcoma is the most frequent sarcoma of soft tissues; the poor prognosis of the alveolar type is assessed by the case of this 16-year old girl; this tumor may progress as a systemic disease and present as a leukemia with rapid impairment of general health, enlargement of lymph nodes, cutaneous nodules and anemia.

[Syringocystadenoma papilliferum. A case located on the knee].

Syringocystadenoma papilliferum is an infrequent hamartoma of the sweat glands, usually of the scalp or temporal area. We observed a syringocystadenoma papilliferum in a young patient from Senegal. The lesion was unique and presented as a round 4 cm plaque with a red smooth surface. The diagnosis was based on the histologic examination. Complete surgical exeresis was performed. Localization on the knee is very unusual.

[Crusted (Norwegian) scabies in Dakar (Senegal)].

Between January 1993 and June 1997, 30 patients with crusted scabies were seen at the dermatological clinic in Dakar (Senegal). Seventeen of these patients were male and 13 were female. Six were children aged 5 to 15 years and 24 were adults aged 18 to 70 years. Diagnosis of crusted scabies was straightforward because this condition, which was rare in Dakar before 1990, has become much more common and is now familiar to Senegalese dermatologists. The infection presented as an extensive scaly or crusted eruption with symmetrical lesions affecting the hands, feet, knees, elbows and ears in particular. Scalp involvement was reported in 25 patients. Erythrodermia was present in 4 cases and pachyonychia in 4 cases. Twenty-seven of the 30 patients had moderate or severe pruritus, whereas an absence of pruritus is regarded as a classical characteristic of crusted scabies. Diagnosis was readily confirmed by examination of hyperkeratotic material under the microscope: numerous mites and eggs were present. The two most common etiological factors were auto-immune diseases (6 cases, 4 of whom were receiving no steroid or other immunosuppressive treatment at the time of onset of crusted scabies) and malnutrition (5 of the 6 children in the study). The other associated conditions identified were: physical debilitation (4 cases), HIV infection (3), mental disability-Down's syndrome (3) and long term use of topical steroids for artificial depigmentation (2). Two patients were immunocompetent and 5 patients died shortly after diagnosis, before any underlying conditions could be identified. Seven patients were cured with benzyl benzoate. Seven others, all adults, received a single oral dose of ivermectin (200 mg/kg) and topical kerolytic drugs. Ivermectin was ineffective in 1 case, and an improvement was observed in another case, although a complete cure was achieved only after a second dose. The other patients were all cured and showed no signs of scabies one month after ivermectin treatment. A recurrence was observed in 3 patients a few months later however, suggesting that these patients were reinfected. No side effects were reported in any of the patients treated with ivermectin.

[Mycetomas in Africa].

Mycetoma is the pathological process in which exogenous fungal or actinomycotic etiological agents generate grains. These agents belong to two groups: fungi and aerobic actinomycetes. Eumycetoma (caused by fungi) and actinomycetoma (caused by actinomycetes) must be distinguished as their treatments are different. These causative agents are introduced by traumas. Mycetomas are frequent in the northern tropical zones of America in Mexico and Venezuela, Africa in Senegal, Mauritania and Sudan and Asia in India, but can also be observed beyond these areas. In Africa, a high endemicity has been noted in a Sahelian band spanning from Senegal and Mauritania in the west to Somalia and the Republic of Djibouti in the east where there are long dry seasons and short rainy seasons. In this zone, M. mycetomatis (fungi) and S. somaliensis (actinomycetes) are predominant. A. pelletieri is common only in West Africa. Rainfall influences the distribution of these agents. S. somaliensis is more often found in desert areas, and A. pelletieri in more rainy areas. Mycetoma is more frequent in males and affects the age group between the second and fourth decades. Most of the patients are outdoor workers. In Africa, the foot is the most frequent localisation of the disease followed by the leg. Mycetoma is characterized by tumefaction, subcutaneous nodules and in most cases discharging sinuses that drain exudate containing grains. It gradually invades the tissues and bones causing a functional disability. Bone involvement depends on the duration of the disease, the site of the lesion and the causative agent. Invasion of lymph nodes is observed in rare cases, usually with actinomycetes.(ABSTRACT TRUNCATED AT 250 WORDS)
