The profile of drug users in Tunisia: Implications for prevention.

BACKGROUND: Despite cultural, religious, and legal constraints on Muslims against the consumption of drugs, usage and misuse do exist. Drug addiction in Tunisia is a wide-spread problem and is destroying the lives of many individuals and families. AIMS: To examine the socio-demographic characteristics of substance users and to identify the drugs commonly used. METHODS: In this cross-sectional study, all the patients admitted at the addiction treatment center ''Aide et Ecoute'' in the period from January 2014 to September 2014 formed the sample of the present study. RESULTS: Only two hundred males were found to get treatment in the addiction center for various addictions. Among them, 65.9% were not married and 59.5 % had involvement with criminal justice. The mean age was 33.32 years and the mean age for starting substance use was 17.30 years. Substance use was higher (90.6%) in less educated people (secondary or below) and in urban population (73.2%). The most common substance misused was Buprenorphine (34.8%). There was a significant relation between buprenorphine consumption and immigration p= 0.013. CONCLUSION: Our observations point towards the vulnerability of younger age and immigrated population towards substance use and hence, it is proposed preventive health policies in this regard.

Opiate withdrawal syndrome in buprenorphine abusers admitted to a rehabilitation center in Tunisia.

BACKGROUND: Illicit use of high dosage buprenorphine has been well documented in several countries, including Tunisia. OBJECTIVES: The aim of this survey is to assess the buprenorphine withdrawal syndrome time course, and how it may be affected by the population characteristics among subjects admitted to a rehabilitation center in Tunisia. METHODS: A prospective research has permitted study of the socio-demographic characteristics and assessment of buprenorphine withdrawal syndrome among 32 subjects admitted for buprenorphine dependence by using the clinical opiate withdrawal scale. An ANOVA was conducted to examine the effect of different factors on the withdrawal scores. RESULTS: 32 subjects were included. Among them 30 were males, 27 had been injecting buprenorphine, 16 were poly-drug abusers and 2 had a history of mental disorders. Buprenorphine withdrawal syndrome was of a mild intensity and had a delayed onset. Withdrawal mean scores varied between 0 and 9, and maximum values were reached at day 21. These scores varied significantly over time (p<0,001). The sex v time interaction and the mode of consumption of buprenorphine had significant effects on the withdrawal scores (p<0,001). The poly-drug consumption and the history of mental disorders did not have any significant effect on the withdrawal scores. CONCLUSION: This study has permitted description of buprenorphine withdrawal syndrome among patients going through a detoxification treatment at a rehabilitation center. Understanding this syndrome would help elaborate effective and suitable buprenorphine dependence management plans.

Clinical and laboratory findings in 8 patients with Bloom's syndrome.

UNLABELLED: Bloom's syndrome is a rare autosomal recessive disorder caused by germline mutation of the BLM gene. The objective of this study was to illustrate the clinical, biological and genetic characteristics of this syndrome through Tunisian series. We report in a retrospective study 8 case of bloom's syndrome observed during 20 years. RESULTS: Our patients were 4 males and 4 females issued from 5 families. For all patients, the parents were consanguineous. The age was 13 to 39 years. The telangiectatic erythema was developed in all the patients between 6 months and 2 years old on the cheeks, on the nose, on the lips and the lower eyebrows. The photosensitivity was constant and was complicated by vesicules and bullae for 5 patients who had extensive lesions, three patients noted accentuation of their telangiectasic erythema. An improvement with the age was noticed for the first four patients. The growth deficiency was observed for all patients. It was marked, between -2 and -4 DS (standard deviation). The number of sister chromatid exchange was increased to twelve fold comparatively to normal subjects. Two patients developed a breast cancer; the evolution was fatal in one. Another patient developed a leukaemia, the evolution was also fatal. CONCLUSION: Bloom's syndrome is a rare genodermatitis. All the patients presented three symptoms: telangiectatic erythema, growth delay and photosensitivity associated with immunodeficiency. There is significant risk of cancer, so that follow up of patients is mandatory.

[Sexual dysfunction after colostomy]. / Troubles sexuels après colostomies définitives.

BACKGROUND: Sexual disturbances after colostomy are various. However, they probably remain underestimated in societies where sexuality is still a taboo issue. THE AIM of this prospective study was to evaluate the possible sexual behaviour and the post operative sexual disturbances in patients whome underwent colostomy. METHODS: The group was devided in 10 male and 11 female patients. Seventeen patients (81%) were married, 3 widowed and 1 unmaried. RESULTS: Sexual disturbances were found in 47% of patients. There was a lack of interest in sexual relations in 2 women, a resolved premature ejaculation in one case, post operative dysparenia in 2 female patients, a retrograde ejaculation in a 60-year-old man, impotence in a 46 years old patient, and a premature ejaculation in a 36-year-old man. The frequency of sexual disturbances (47%) in our series was close to that reported in the literature (50%). CONCLUSION: The sexual disorders are more common in male patients, the most frequent being ejaculatory dysfunction. In women, dyspareunia is the most common disorder. The particular case of colostomy in homosexuals remains a current issue.

[Clinical and histological study of lupoid cutaneous leishmaniasis (16 cases)]. / Etude anatomoclinique de la forme lupoïde de la leishmaniose cutanée (16 cas).

INTRODUCTION: Zoonotic cutaneous leishmaniasis (CL) is characterised by a major clinical polymorphism, especially the lupoid type. The aim of our study was to precise the anatomic and clinical particularities of this clinical form of CL. MATERIALS AND METHODS: The present work was a prospective 1-year study. In all patients, the epidemiologic and clinical characteristics were identified, together with those regarding disease progression. Standard cutaneous biopsies were carried out for all study patients. RESULTS: The lupoid form was observed in 15% of the patients. It was clinically characterised by a lupoid aspect with papular and squamous placard surrounded by a satellite papule, a short duration of disease progression (28 months in average) and a preferential localisation at the level of the face and the elbow, statistically proven. At the histological level, epidermic hyperplasia was found in 93.8% of the cases; an inflammatory polymorphic dermic infiltrate consisting of lymphocytes and plasmocytes was found in all patients; granulomas were noted in 50% of the cases, and isolated epitheloid cells were observed in the derm of 3 patients. Amastigotes were rarely observed. DISCUSSION: In our series, the lupoid form was characterised with a short and non chronic evolution and two preferential sites for the affection: the face and the elbow. At the histological level, the lupoid type of CL appeared characterized by a high frequency of granuloma, usually organized, and rare amastigotes. However, the histology of authentic lupoid forms can be non granolomatosic.

[Epidemio-clinical profile of skin cancer in southern Tunisia]. / Profil epidemio-clinique des cancers cutanes dans le sud Tunisien.

BACKGROUND: Skin cancer (SK) frequency is increasing all over the world. AIM: We report a clinical and epidemiological study of SK in the south of Tunisia through a 1476 cases series. METHOD: On the basis of a retrospective study, we report the clinical and epidemiological data collected from files of patients with skin cancers seen during a 24-year-period (1979-2002). RESULTS: Our series was composed of 1476 patients, with an incidence of 615 cases/year. The mean age was 55 years. Epithelial skin carcinomas were the most common (1288 cases, 87.3%). Basal cell carcinomas were found in 890 patients (69%) and squamous cell carcinomas in 398 (31%). The mean age was 60 years. The phototype III was the most common (52.8%) among these patients. Skin melanomas were found in 71 cases (4.8%). The mean age was 54 years with a female predominance (60.6 %). Kaposi sarcoma was found in 4.5% of patients. The mean age was 64.3% and a male predominance was found (80% of cases). Two patients with Kaposi sarcoma (33%) were HIV positive. Dermatofibrosarcoma protuberans was reported in 2% of patients and skin lymphoma in 1.7%. CONCLUSION: The mean age is relatively low in our series. The increase in the incidence of skin cancers is probably related to the climatic conditions, the ageing of the population and to the changes in the social, economic and cultural aspects in the country. The male predominance is changing toward an equal distribution between both sexes probably in relation to the present similarity in the life style and work conditions.

[Sweet syndrome: retrospective study of 54 cases]. / Syndrome de Sweet: étude rétrospective de 54 cas.

INTRODUCTION: Sweet syndrome is the most common neutrophilic dermatosis. We studied its natural history and epidemiologic, clinical, and therapeutic characteristics from a series of 54 cases. MATERIALS AND METHODS: This retrospective study examines 54 cases collected over a 10-year-period. Diagnosis was based on clinical and histological criteria. RESULTS: Patients' mean age was 47 years. The sex ratio was 8 women for every man. Disease developed most often in autumn and onset was sudden in all patients. Untypical aspects were found in 20 patients. Lesions were located mainly on the arms (43 cases) and legs (33 cases). No mucous membrane involvement was observed. Histological testing found leukocytoclastic vasculitis in 8 cases. Sweet syndrome was idiopathic for 38 patients. Lesions began at the site of previous trauma for 9 patients, occurred during pregnancy for 2, and were associated with cancer for 3. First-line treatment was colchicine for 23 patients and oral steroids for 12. Six patients had recurrences and 2 patients had relapses. COMMENTARY: This large series of patients with Sweet syndrome differs from other reports by the frequency of untypical aspects and post-traumatic forms, as well as the rarity of association with cancer. Histological findings of vasculitis do not rule out a diagnosis of Sweet syndrome.

[Epidemiologic, clinic and allergologic profile of atopic dermatitis in south Tunisia]. / Profil epidemiologique, clinique et allergologique de la dermatite atopique dans le sud Tunisien.

BACKGROUND: Atopic dermatitis (AD) is the collection of the cutaneous inflammatory manifestations which are chronic or repetitive associated with the other atopic diseases. The prevalence of the AD varies from one country to another. AIM: The aims of this work in to study the allergolicol, clinical and epidemiological profile of the AD in the south of Tunisia. METHODS: our study is prospective about 100 cases reported in a period of 18 months. The diagnostic was carried on the criteria of Hanifin and Radjka. For every patient we studied the biographical data and the clinical manifestations of AD. Allergoloigical explorations (pricks-tests) were carried out. RESULTS: the overage of the patients was 104 months with extremes of 5 moths and 43 years. 65 % of our patients were men. At the beginning the average was 61 months with extremes of 2 months and 37 years. 55 patients had antecedents of family allergy and 34 had antecedents of personal allergy. The former preceded the AD in 28 cases. We didn't note any significant relation between the existence of familial allergy and the severity of the AD. In the statement, the principal factor was the contact with the house dust (33 cases), the duration of maternal breastfeeding (overage 13.7 months) didn't influence neither the SCORAD, nor the beginning age of the AD. The date of beginning of food diversity (overage 6.16 months) didn't significantly influence the severity of the illness. The clinical aspect was a sharp eczema in 71% of the cases according. To the SCORAD score. The AD was judged to be weak in 5 cases, moderate in 68 cases and severe in 27 cases. The number of rise per year varied from one rise (75 cases), to more then 6 rises per year (6 cases). The evolution was chronic in 6 cases. The pricks test showed to be positive for the accariens in the group of aeroallergen in 9 cases among the 35 cases tested, and positive for the whole egg in the group of trophallergen in 5 cases among the 13 cases tested.

[Mal de Meleda. 16 cases]. / Le mal de meleda. A propos de 16 cas.

Mal de Meleda is a recessive transgression palmoplantar keratoderma. We report the epidemiological, clinical and progressiveness aspects of the disease in 16 patients of a large consanguineous tunisian family. The age ranged from 3 to 90 years. Nine were male and 7 female patients. Onset in early infancy was characterized by erythema of the palms and soles, followed by a diffuse yellowish hyperkeratosis. Thickness of the dorsal aspect of the fingers started in childhood. Extension of hyperkeratosis to the dorsal of the hand were reported only in adults and usually precede the involvement of the feet Palmoplantar hyperhidrosis with fetid odor between the toes was frequently seen as well as conical distal phalanges. In some adults keratoderma gave contracture of the fingers leading to limitation of movements Mal de Meleda must be differentiated from other recessive palmoplantar keratoderma such as Papillon-Lefévre syndrome and Mal de Naxos. the remaining inherited palmoplantar keratoderma being autosomal dominant. Mal de Meleda is a rare disease but is still relatively frequent in some tunisian regions, due to the high rate of consanguinity Mal de Meleda remains an afflicting and disabling disease.

[Beneficial effects of antimalarials in the treatment of generalized granuloma annular in children]. / Interet des antipaludeens de synthese dans le traitement du granulome annulaire generalise de l'enfant.

Granulma annulare is a polymorphic granulomatous disease of the skin. It has a chronic course and affects mainly children and young adults. We report two cases of generalized granuloma annulare in children successfully treated with antimalarials. Two children, 6 and 12 years of age, without clinical history, presented with multiple granuloma annulare lesions which did not respond to potent topical steroids. Blood glucose level was normal. These lesions responded to small doses of antimalarials. No side effects were noticed. Compared with other drugs, with potential important side effects for children. Small doses of antimalarials might be beneficial in the treatment of generalized granuloma annulare.

[Ophthalmic manifestations of lipoid proteinosis]. / Manifestations ophtalmologiques de la hyalinose cutanéo-muqueuse.

INTRODUCTION: Lipoid proteinosis (LP), also known as hyalinosis (or lipoidosis) cutis et mucosae or Urbach-Wiethe disease, is a rare autosomal recessive disorder. It is associated with deposits of protein-lipid complexes in various tissues including the skin and mucous membranes. Ophthalmologic manifestations are frequent and can affect visual prognosis. CASE: This 28-year-old patient presented vesiculobullous lesions of the face that developed into varioloid scars associated with hoarseness. Ophthalmologic examination revealed unilateral lesions including hyaline deposits on the palpebral margins, iris, and trabecular zone, complicated by uveitis, cataract, and glaucoma, which caused the functional loss of the left eye. Histological examination of a cutaneous biopsy confirmed the diagnosis. DISCUSSION: Involvement of the eyelids is characteristic, and moniliform blepharosis is pathognomonic and frequent. This case featured a rare intraocular form (uveitis). Deposits may be found on the conjunctiva, cornea, trabecula and Bruch membrane. Conjunctival or cutaneous biopsy confirms the diagnosis. Available treatment is quite limited.

[Cutaneous manifestations of chronic hemodialysis. Prospective study of 363 cases]. / Manifestations cutanées chez les hémodialysés chroniques. Etude prospective de 363 cas.

OBJECTIVE: Chronic hemodialysis patients experience frequent and varied cutaneous manifestations, of often hypothetical pathogenesis. The aim of this work is to assess the prevalence and nature of these cutaneous lesions and discuss some pathogenic mechanisms. METHODS: This prospective study was conducted from 1 February through 30 April 1996. It included 363 hemodialysis patients in seven centers. Each patient was interviewed and examined. RESULTS: There were 210 men and 153 women. Their mean age was 50.6 years. The total duration of hemodialysis ranged from 1 to 192 months, with a mean of 52.4 months. 88% of the patients had cutaneous manifestations. Pruritus was reported by 44.8%. It appeared after hemodialysis began for 82.1% of them. Cutaneous xerosis was observed in 69%. Changes in pigmentation were observed in 17% of cases, primarily involving hyperpigmentation of photo-exposed areas. In 6 patients, skin, hair, and exoskeleton began to turn lighter 10 months to 8 years after hemodialysis. Follicular hyperkeratosis was observed in 15%. One patient had a confirmed case of perforating follicular dermatosis. Disorders of the exoskeleton (18.5% of cases) were represented mainly by thin nails and subungual hemorrhages. Other cutaneous manifestations included petechiae and ecchymoses (66%), folliculitis-type infections (9%), subcutaneous calcifications (2 cases), cutaneous pseudoporphyria (2 cases), and eczema around the fistula (11.5%), due essentially to locally-applied products. CONCLUSION: Cutaneous manifestations in chronic hemodialysis patients are frequent and polymorphous. While most have long been known, lightening of skin, in particular, others have been discovered more recently. Their pathogenesis is most often poorly elucidated. Treatment is often symptomatic. Dialysis and renal transplantation constitute the best treatment.

Risk factors for erysipelas of the leg in Tunisia: a multicenter case-control study.

BACKGROUND: Risk factors for erysipelas (cellulitis) were rarely evaluated in controlled studies. Regional variations of these risk factors have never be assessed. OBJECTIVE: To assess risk factors for erysipelas of the leg in Tunisia. SUBJECTS AND METHODS: Case-control study in seven hospital centers in Tunisia. Cases were 114 consecutive patients with erysipelas of the leg [sudden onset (<24 h) of a well-demarcated dermo-hypodermatitis with fever or chills]. Two controls were matched to each case for age, sex, and hospital (n = 208). Main outcome measures are local and general suspected risk factors for erysipelas of the leg. RESULTS: In multivariate analysis, disruption of the cutaneous barrier (i.e. traumatic wound, toe-web intertrigo, excoriated leg dermatosis or plantar squamous lesions) and leg edema were independently associated with erysipelas of the leg, with respective odds ratios of 13.6 (95% confidence interval: 6.0-31) and 7.0 (1.3-38). No association was observed with diabetes, alcoholism, or smoking. CONCLUSIONS: We confirmed the major role of local risk factors and the minor role of general risk factors for erysipelas of the leg, in a setting different than the one previously studied. Detecting and treating toe-web intertrigo and traumatic wounds should be considered in the prevention of erysipelas of the leg.

[Cutaneous metastasis of Crohn's disease]. / Localisations cutanées métastatiques d'une maladie de Crohn.

INTRODUCTION: Involvement of the skin in Crohn's disease is rare. We report the case of a young woman presenting cutaneous nodules revealing a Crohn's disease. CASE REPORT: R. K. a 19 year old woman was admitted the impatient clinic for a 2 week history of nodular lesions of the extremities. Simultaneously, she had watery diarrhoea and abdominal pain associated with a bad general condition and fever. Skin examination showed ulcerated lesions with a non infiltrated inflammatory bader of the left food and the right calf associated with an abscess of the left forearm. Skin biopsy showed an inflammatory infiltrate of the deep dermis with tuberculoid noncaseating granulomas. Colonoscopy demonstrated multiple ulcers, a "globlestone appearance" of the glow and segmental glitis. Colonoscopy was followed by a peritonitis which made steroid therapy questionable. Meanwhile, the patient underwent a colonostomy and was fed intravenously, the skin lesions resolved. A follow up colonoscopy demonstrated colon polyps, and the biopsy of the colon showed features of colitis and "follicular" duodenitis which was in concordance with the diagnosis of Crohn's disease. COMMENTARIES: Usually, cutaneous lesions in Crohn's disease are consistent with nodules and granulomatous fissures of the grain. Involvement of the mucosa is rare. We report the case of "metastatic" localisation of nodular abscesses in Corhn disease. Improvement of cutaneous lesions might be explained by the nonuse of the digestive track allowed by the parenteral supplementation.

[Ophtalmologic manifestations of the xeroderma pigmentosum]. / Les manifestations ophtalmologiques du xéroderma pigmentosum.

Xéroderma pigmentosum (XP) is a rare genetic disease characterised by defective repair of DNA damage. We report a retrospective study of the ophtalmologic manifestations of 16 patients with xéroderma pigmentosum, the ophtalmologic manifestations were present in 62% of cases. The age of patients was 7 to 22 years. Photophobia were seen in all patients. Multiple tumors were seen with 5 squamous cell carcinoma. Tumor size was 1 to 6 cm. Ocular involvement occurs in up to 80% of cases of XP. Infection, néoplasia, conjonctiva are the most commun finding. Patients with XP can acquire squamous cell carcinoma at an early age.

[Kaposi' s sarcoma. A series of 65 cases]. / La maladie de Kaposi. Une série de 65 cas.

Kaposi sarcoma (SK) is characterized by proliferation of vascular and spindle-shaped cells with variable clinical presentations. The association with AIDS modifies the profile of this disease. The pathophysiology seems to be based on the major role HHV-8. The goal of this work was to specify the profile of this disease in our region through a retrospective study of 65 cases of SK over a 23-year period (1981-2003). In our series, the classic form prevailed 163 cases (96.9%)]. One patient had a secondary form due to steroid therapy and another patient had a KS associated with AIDS. A male prevalence was noticed (M/F: 2.8). Cutaneous lesions were dominated by papulo-nodular lesions (90.9%) of the lower limbs (92.3% of the cases). Mucous lesions were present in 15.4% of the cases. Therapeutic abstention was decided in 38.4%. Surgical excision was indicated in 35.4% of cases, radiotherapy in 4.6% of the cases and chemotherapy in 23% of the cases. The classic form of KS is the most frequent in our area; the other forms remaining rare.
