[Dermatomyositis with cutaneous necrosis revealing a fallopian tube carcinoma].

INTRODUCTION: Adult dermatomyositis is a rare inflammatory myopathy associated with typical cutaneous lesions and an increased incidence of internal malignancies, notably cancers of the female genital tract. Nevertheless, fallopian tube carcinoma is exceptionally associated with dermatomyositis. EXEGESIS: We report an unusual case of dermatomyositis because of cutaneous necrosis revealing a cancer of the fallopian tube. CONCLUSION: Predictive factors of cancer can improve prognosis of dermatomyositis due to earlier diagnosis of associated cancer. In our observation as in literature review, cutaneous necrosis lesions are highly predictive of an associated neoplasia even as rare as a fallopian tube carcinoma.

Ethical dilemmas in care for HIV infection among French general practitioners.

A survey was carried out in May-June 1992, in the city of Marseille (South-Eastern France), to analyze attitudes towards ethical issues associated with the care of HIV-infected patients in a random sample of general practitioners (GPs) (telephone interviews; answer rate = 78.6%; n = 313). A total of 70.6% were consulted by HIV carriers and 48.9% regularly took care of these patients over the past year. Multi-dimensional analysis showed that support for HIV mandatory screening was related to lack of knowledge and experience with HIV infection, high perception of risks associated with HIV care, and the individual characteristics of GPs, such as religious beliefs and intolerance to uncertain situations. GPs with experience of regular care of HIV carriers had the same opinions than the rest of the sample about 'creation of specialized hospitals for AIDS patients' and similar attitudes toward HIV testing 'without patients' consent' or breaching of confidentiality of HIV diagnosis. Debates on ethical issues among GPs cannot be reduced to a simplistic division of a 'liberal group' highly involved in prevention and HIV care and a 'conservative' majority more or less inclined to stigmatize HIV-infected patients. Ambiguous messages on these issues from health authorities and professional ethical bodies may have very negative impacts on the attitudes of primary care physicians regarding the acceptability of HIV-infected patients.

[Cutaneo-mucosal hyperpigmentation in AIDS. 4 cases].

Four cases of pigmentation of the skin and mucous membranes in homosexuals of the IVC1 group (CDC classification) are reported. The aetiological investigation, although incomplete, pointed to a medicinal origin which could not be formally confirmed. The drugs suspected were azidothymidine, pyrimethamine and ketoconazole. There was no clinical or laboratory evidence of adrenal insufficiency. The few published cases of cutaneo-mucosal pigmentation in HIV infection, often mimicking adrenal insufficiency, emphasize the need for thorough toxicological investigation; this may avoid prescribing an unnecessary and dangerous corticosteroid therapy which might be harmful in these deeply immunocompromized patients who often have multiple infections.

[Neuropathies and HIV retrovirus infections].

Neurologic complications are frequently observed during HIV-related infections and particularly in AIDS. According to the literature, these complications more often pertain to the central nervous system (CNS) than the peripheral nervous system (PNS). A prospective study was carried out in order to determine the frequency and type of PNS disorders during HIV infections, the neurotropism of which is now well established. Forty-one HIV-infected patients - 5 asymptomatic subjects, 14 ARC (AIDS-related complex) and 22 AIDS patients - were studied from a clinical and biological angle; 40 equally underwent an EMG and nervous conduction velocity tests, 26 a lumbar puncture and 25 a nervous biopsy (associated in three cases with a muscular biopsy). The study showed that a PNS-alteration is extremely frequent (36/41, or 88% of all cases), generally mild or even subclinical (17/36); most often, the aspect is that of a sensitive axonal polyneuropathy. More severe types (polyradiculoneuritis, sensorimotor polyneuropathy, etc.) are equally observed, but much rarer. Whatever their form may be, the PNS-lesions can be observed in so-called asymptomatic subjects (2/5) as well as ARC (12/14) and AIDS (22/22) patients. They are the manifestation either of a direct lesion of the nerve through HIV, or of immune mechanisms (of humoral or cellular mediation) or of both mechanisms combined.

[Stewart-Treves syndrome. 2 cases with an ultrastructural study].

The authors present an ultrastructural study of two cases of Stewart-Treves syndrome in elderly women. Under light microscopy, the dermal and hypodermal proliferations showed vascular features which were more clearly preceptible in the second case than in the first. Ultrastructural studies showed, in the first case, clefts containing erythrocytes and surrounded by neoplastic cells which were linked by zonulae adherentes. A rudimentary form of basal membrane was also noted, with an exterior lining of pericyte-like cells. In the second case, typical capillary vessels were bordered by endothelial cells containing a few pinocytotic vesicles and microfilaments, in contact by zonulae adherentes. The walls of these vessels consisted of a clearly defined membrane lined with pericytes, and constituting, in some areas, an anastomotic network due to the swelling of the endothelial cells. Ultrastructural study suggests an angiosarcomatous origin of these lesions. Finally, the article includes a review of the literature.

[Hormonotherapy in acute, idiopathic hirsutism, and seborrheic alopecia (author's transl)].

It has been established that, through skin responds to circulating androgens, it can also produce androgens from precursors. Therapy can address either of the two following physiopathological steps: the secretory step can be countered by replacement or suppressive therapy which is now fairly well mastered; the target-organ step opens new possibilities concerning receptor abnormalities and receptor control. The medical literature was reviewed for data on hormonal therapy for women with acne, idiopathic hirsutism and seborrheic alopecia, three conditions which are usually only partially improved by cosmetic treatment.
