[Mucosal localization of leishmaniasis in Tunisia: 5 cases].

INTRODUCTION: Three epidemic-clinical forms of leishmaniasis are found in Tunisia: the sporadic cutaneous form due to L. Infantumin in the North, the zoonotic cutaneous form due to L. Major in the Center and South-West, and the chronic cutaneous form due to L. Tropica in the South. We report 5 cases of mucosal leishmaniasis diagnosed in a Dermatology unit in Tunis. OBSERVATIONS: Four women and one man, from the North-west of Tunisia, with a mean age of 42.4 years (range: 8-75 years) presented with leishmaniasis. The lesions were localized on the mucosa of the lips in 4 patients and on the endonasal mucosa with infiltration and nasal obstruction in a 75 year-old female patient. Diagnosis of leishmaniasis was established on direct examination in 4 cases and histological examination in 3 cases and by culture in NNN milieu for one patient exhibiting a MON5 L. Major leishmaniasis. All the patients responded well to treatment with intramuscular meglumine antimoniate (Glucantime). In our 5 patients, the mucosal involvement was not as mutilating, nor resistant to treatment, as that described for the cutaneous-mucosal forms in the New World. COMMENTS: Mucocutaneous leishmaniasis, endemic in Central and South America, are due to L. Braziliensis. They provoke mutilating and disfiguring lesions, resistant to treatment. In Tunisia, the forms of the disease observed are dermotropic, usually responsible for cutaneous leishmaniasis. However, mucosal involvement is not uncommon and is characterized by the absence of mutilating lesions and the excellent response to treatment.

[Latex allergy -- when uncertainty remains the only certainty].

Latex devices release allergenic proteins which are responsible for immune IgE mediated reactions. Casual surgical gloves are most often responsible for contact urticaria. Other allergic manifestations include conjunctivitis, rhinitis, asthmatiform dyspnoea and diverse gastro-intestinal troubles. Cardiovascular collapse and anaphylactic shock are possible. Physicians and the paramedical staff are particularly affected by the allergy to latex proteins. Multi-operated patients and those under prolonged health care using latex-made medical probes also present a high-risk group for this type of allergy.

[Melanoma in xeroderma pigmentosum: 12 cases].

BACKGROUND: Xeroderma pigmentosum is a rare genodermatosis, with a defect affecting recovery of ultraviolet-induced damages and characterized by a high rate of malignancies of the exposed skin areas. We studied melanoma features of patients with xeroderma pigmentosum. PATIENTS AND METHODS: A retrospective study of xeroderma pigmentosum patients admitted to the Charles Nicolle Hospital of Tunis between 1973 and 1998. RESULTS: Two hundred sixteen patients with xeroderma pigmentosum were registered. Melanoma was present in 12 patients, 7 females and 5 males. Two patients were sisters. Cutaneous melanoma was found in 8 patients. Four patients presented with metastatic melanoma. The median age for development of the first melanoma was 17.5 years. All of the cutaneous melanomas were found on the face. Lentigo malignant melanoma was reported in 3 cases. The tumors were treated with surgical excision. Except for a melanoma affecting the orbit, characterized by a fatal outcome, no metastases were detected at the different investigations. DISCUSSION: Melanoma occurs frequently in patients with xeroderma pigmentosum, it has been reported in 5.5 p. 100 of cases and 11.3 p. 100 of patients with cutaneous carcinoma. The age of onset was low: 17.5 years. It appeared later than the carcinoma. The location of cutaneous melanoma in face in xeroderma pigmentosum patients indicates that they were caused mainly by sunlight exposure. Lentigo malignant melanoma was the most frequent type. Prognosis is difficult to define owing to the large number of other cutaneous malignancies. Apart from one case of rapidly fatal orbital melanoma, we recorded long survivals even in cases of melanoma revealed by metastases.

[Atopic dermatitis in Tunisia: epidemiological and clinical aspects].

INTRODUCTION: The prevalence of atopic dermatitis is usually high in western countries, varying from 18 p. 100 to 20 p. 100. Recent studies suggest an increasing of this frequency. The aim of our study is to determine the epidemiological and clinical characteristics of atopic dermatitis in Tunisia through the analysis of a retrospective cohort. PATIENTS AND METHODS: We retrospectively studied all the medical reports of atopic dermatitis registrated in the department of dermatology during a 7 years period (1992-1998). We analysed epidemiological and clinical features of every medical report. We used diagnosis criteria of Hanifin and Rajka. RESULTS: Four hundred fifty-one cases of atopic dermatitis have been diagnosed (54 adults and 397 infants). Relative frequency of new cases of atopic dermatitis compared to new diagnosis was 0.37 p. 100 in 1992 and 0.72 p. 100 in 1998. Mean age was 3.2 years. A personal history of atopy was observed for 15.2 p. 100 of patients and a family history of atopy for 35.9 p. 100. A few numbers of complications were observed. Bacterial infections interested 15.3 p. 100 of cases. Hospitalisation was needed for 4 patients (0.88 p. 100). Class III and IV topical corticosteroids were usually used (84.8 p. 100). Potent corticosteroids (class I) were required for only 3.2 p. 100 of cases. CONCLUSIONS: We notice a low frequency of atopic dermatitis in this study and a predominance of mild forms of the disease. Other studies are needed to confirm these results and to determine the prevalence of atopic dermatitis in Tunisia.

[Undesirable reactions from contact with marine organisms].

The contact of some marine organisms with the skin may prove to be traumatic and sometimes very dangerous. Some coelenterates, fishes, urchins, sea snakes, cephalopods, molluscs and other sea organisms are responsible for dermatological lesions, associated or not with toxic or allergic reactions exhibiting systemic effects.

[Epidemiologic/clinical profile of condyloma acuminata in a dermatology service. Report of 232 cases].

The incidence of condylomata acuminata is increasing in all countries. They are one of the most frequent sexually transmitted disease (STD). The authors reported the experience of the department of Dermatology of charles Nicolle's hospital between the year 1979 and 1998. This HPV infections were in the third position of the STD and occurred mainly in young males. The clinical lesions are genital condylomata. They were successfully treated with electrodessication or cryotherapy.

[Profile of bullous pemphigoid. A report of 47 cases].

We report forty-seven cases of bullous pemphigoid recorded in the dermatology department of Charles Nicolle hospital in Tunis during 16 years. In Tunisia, bullous pemphigoid is at the second rank of acquired autoimmune bullous skin diseases, after pemphigus. The profile of bullous pemphigoid in our series differ from that reported in the literature by the more young age (67.2 years) and the male predilection but don't present any clinical an epidemiological particularity. Three atypicals forms were observed: a vesicular form, a localized form and a infantile form. Systemic corticosteroids were choice treatment for our patients.

[Evaluation of the frequency of oncogenic HPV in venereal condyloma. Prospective study of 24 patients].

UNLABELLED: Human papillomavirus (HPV) infection tend to be the most prevalent sexually transmitted disease (STD), and "high-risk" HPV types are correlated to intra-epithelial neoplasia, especially cervical cancer. The aim of this study was to evaluate the frequency of "high risk" HPV types in condyloma. PATIENTS AND METHODS: A non randomised prospective study was performed, including 24 patients with condyloma examined in the department of Dermatology of Charles Nicolle's hospital. Molecular hybridisation method was realised for all patients to identify HPV type. RESULTS: Mean age of the 24 patients was 37.8 years Ratio (male/female): 1.4 In 21 patients HPV DNA was detected 2 women had "high risk" HPV type (9.5%).

[Comparative study of the efficacy and tolerance of 12% glycolic acid cream and 0.05% retinoic acid cream for polymorphic acne].

UNLABELLED: Topical retinoic acid has demonstrated its efficacy in acne. Glycolic acid has also keratolytic action and could be interesting to treat acne. OBJECTIVE: To evaluate the efficacy and safety of topical glycolic acid (Glyco A 12%) and retinoin acid (Kefrane 0.05%) on facial acne lesions. METHOD: It was a randomised double blind study of 40 patients, divided in 2 groups, 20 receiving GlycoA cream (Group A) and 20 receiving Kefrane cream (group B). Medical exam was realised by the same physician at day 0, 21 and 45. The improvement of acne as well as side effects were assessed by both the physician and the patients themselves. RESULTS: 2 patients developed severe eczema of the face and were excluded (one from group A and one from group B). 22 patients followed totally the study. 90% of group A and 83.3% of group B patients improved significantly their lesions. A comparative tolerability was observed for both groups. CONCLUSION: Glyco A cream could be a good treatment for acne even in dark skin patients.
