The effect of natural extracts on laser burn wound healing.

BACKGROUND: Despite the achievements in modern medicine, there is no effective natural treatment of second-degree burns till now. Therefore, the purpose of this study was to assess the wound-healing efficiency of three extracted oils, from the prickly pear, pumpkin and linseed on partial-thickness burns induced by fractional CO2 laser (an innovative up-to-date technique) in rats. MATERIALS AND METHODS: Thirty rats completing partial-thickness burns by fractional CO2 laser were randomly divided into five groups. The burns were measured, photographed, and topically treated daily with saline solution, "CYTOL BASIC," pumpkin-, linseed-, and prickly pear-extracted oils (0.52 µL/mm(2) of oil) until day 7. The response to treatments was assessed by macroscopic, histologic, and biochemical parameters. RESULTS: Due to their chemical composition, the extracted oils showed significant improvements over the control and reference groups during the trial for both general wound appearance and crusting. On day 7, the prickly pear, linseed, and pumpkin oils showed a significant decrease in the healing time (0 cm(2), 0.15 cm(2), and 0.18 cm(2), respectively) when compared to the control and reference groups (1.49 cm(2) and 0.85 cm(2)). Histologic assessment of the prickly pear oil-treated group revealed good healing proprieties compared with the other groups. The collagen content in prickly pear oil-treated group was found to be significantly greater (270.67 ± 7.48) than that in all other groups. CONCLUSIONS: Our experiment has shown, for the first time, a scientific evidence of the efficiency of extracted oils of prickly pear, pumpkin, and linseed on partial-thickness burns.

Paucisymptomatic Dermoid Cyst with Fatal Outcome.

Dermoid cysts of the central nervous system can cause devastating complications because of the mass effect of meningitis due to sinus tract. We report the case of a 5-month-old girl who presented with a crusted lesion of the occipital region of the scalp. Clinical examination noted skin abnormalities suggestive of occult dysraphism. Magnetic resonance imaging (MRI) was recommended, however, 40 days after this evaluation, and before the MRI could be performed, the girl presented with neurologic complications. Unfortunately, the diagnosis of dermoid cyst was made after the onset of severe complications that led to her death. The findings in this case emphasize the importance of more prompt MRI evaluation, particularly in cases where cranial or spinal dysraphism is suspected to have any connection to the skin as a pit or tract. Should we perform an urgent MRI for any cutaneous sign of dysraphism to avoid a dramatic evolution?

Characteristics of DRESS Syndrome in the Elderly: A Comparative Study of 55 Patients.

Background: Drug reaction with eosinophilia and systemic symptoms (DRESS) is a rare drug reaction characterized by a skin rash, eosinophilia, and organ involvement. Objective: Our purpose is to focus on the clinical and epidemiological characteristics of DRESS in the elderly and to identify the incriminated drugs. Methods: This is a retrospective study including patients, hospitalized for DRESS with a RegiSCAR ≥4. The population was divided into 2 groups according to age: 65 years or older (G1) and <65 years (G2). The statistical study was performed using the comparative and multivariate analysis. Results: We included 55 patients (30.9% G1 and 69.1% G2). Skin manifestations were comparable in both groups. Lymphadenopathy was less common in G1 with a statistically significant difference (P = 0.012). Renal impairment was more frequent in the elderly with a statistically significant result (P = 0.005). DRESS in the elderly group was significantly associated with the occurrence of sepsis (P = 0.008). Allopurinol was the most common culprit associated with DRESS in G1 (P = 0.001). Relapses and recurrences were comparable in both groups (P = 0.71). Conclusions: DRESS in the elderly is associated with a high risk of complications, mainly kidney involvement and sepsis. Allopurinol is the most incriminated drug.

Follicular Basaloid Hamartoma and Associated Cutaneous Tumors: Clinical, Histopathological and Dermoscopic Aspects.

Background: Basaloid follicular hamartoma is an uncommun benign neoplasm of the hair follicule. The linear form of basaloid follicular hamartoma can be associated with basal cell carcinoma.OBJECTIVE: We report a case of a patient with multiple basal cell carcinomas developing on a congenital lesion allowing the diagnosis of basaloid follicular hamartoma on histopathology. Methods: Each lesion was evaluated by two dermatologists. All biopsy specimens were routinely stained with hematoxylin-eosin. Results: A 76 year-old-man consulted our dermatology departement for erythematous papules spread over the left lower limb. The lesion had been evolving since birth with flesh-colored to pinkish papules following Blaschko's lines from the root of the thigh to the foot. Three months before consultation, the papules increased in size leading to nodules with sometimes an ulcerated center. Dermoscopy under polarized mode displayed for ulcerated lesions (A) yellow-brownish crusts and ulceration surrounded by blue-grey ovoid nests, subtle short white streaks, brown dots and linear/arborising vessels. For nodular lesions (B), dermoscopic features are white pinkish hue, dotted and linear vessels, brown dots, blue-grey structureless areas and white prominent shiny streaks. There were some more erythematous inflamed and eroded areas in the background with a reversed honeycomb white network on dermoscopy (C), polymorphous vessels, whitish scales, ulcerations and milia-like cysts. The background lesion showed varied dermoscopic structures on a flesh colored slightly pinkish bottom (D). Histolopathology concluded for lesions A to an infiltrating and nodular basal cell carcinoma, (B) and (C) to fibroepithelioma of Pinkus and (D) to basaloid follicular hamartoma. Conclusion: Several case reports have documented dermoscopic features of a solitary basaloid follicular hamartoma. However, further studies are required to specify any reproducible features.

The anti-Müllerian hormone: A useful tool for diagnosis of Polycystic Ovary Syndrome.

BACKGROUND: Polycystic Ovary Syndrome (PCOS) is the most frequent endocrine disorder that affects reproductive-age women with important long-term health implications. As such, the anti-Müllerian hormone (AMH) was proposed as a helpful test to identify women with PCOS. The aim of this study was to determine an AMH cut-off value for the diagnosis of PCOS. METHODS: This was a two-year cross-sectional study including women of reproductive age, diagnosed with PCOS according to Rotterdam criteria (2003). The control group of healthy women was age-matched. AMH was performed using an electrochemiluminescence immunoassay. AMH levels were compared and evaluated with the receiver operating characteristic curve analysis. RESULTS: A total of 130 women were enrolled in this study. Of these, 65 were diagnosed with PCOS, and 65 were healthy. No significant difference was detected in body mass index between the two groups. AMH levels were significantly higher in women with PCOS (p = < 0.001). No significant difference in AMH levels was detected between PCOS phenotypes. A cut-off of 25.1 pmol/L (3.5 ng/mL) could discriminate women with PCOS from controls with a sensitivity of 74% and specificity of 72.3%. The area under the curve was 0.811 (95% CI: 0.73-0.88). CONCLUSIONS: Our study suggests that AMH had good diagnostic potential as a complement to Rotterdam criteria for PCOS diagnosis in reproductive-age women of Tunisian origin.

Efficacy of autologous platelet-rich plasma in the treatment of vitiligo: A 10-patient prospective study.

INTRODUCTION: Vitiligo is an autoimmune disorder characterized by loss of epidermal melanocytes. It has cosmetic and psychosocial impact. The objective of this paper is to evaluate the interest of platelet-rich-plasma in the treatment of vitiligo. MATERIAL AND METHODS: We conducted a prospective study between January 2019 and September 2021. RESULTS: Our descriptive study included 10 patients followed-up for vitiligo refractory to conventional therapies. The mean age was 36.2 years. Sex ratio was 0.25. Prior to platelet-rich-plasma treatment, vitiligo was stable in all cases. The mean number of platelet-rich-plasma sessions received by our patients was 2.6 (1-6). A visible improvement of lesions was obtained after a mean of 1.5 sessions. 40% of patients had obtained repigmentation of more than 50% for at least one lesion. An improvement of more than 75% (grade 4) was noted in 2 cases after a mean duration of 5.5 sessions. 40% of patients had obtained repigmentation of more than 50% for at least one lesion. A percentage of improvement between 50 and 74% (grade 3) was obtained for 2 patients. Four patients had an improvement of less than 25% (grade 1) after a mean of 1.75 sessions. There was no recurrence of depigmentation after a mean follow-up of 6 months (1 to 24 months). CONCLUSION: Our series proves the benefit of platelet-rich-plasma in the treatment of vitiligo. It is a safe and promising option for stable lesions in different body sites with few side effects.

Adverse Reactions Due to the Bacillus Calmette-Guerin Vaccine: Twenty Tunisian Cases.

BACKGROUND: Bacillus Calmette-Guérin (BCG) vaccine is a widely used vaccine. Management of local BCG complications differs between clinicians, and the optimal approach remains unclear. AIMS: We aim to describe the epidemiological, clinical and therapeutic aspects of the BCG vaccine side effects in Sfax. PATIENTS AND METHODS: This was a retrospective study of all the cases of BCG vaccine adverse reactions recorded in the Dermatology and Paediatrics Departments of Hedi Chaker University Hospital of Sfax over a period of 10 years (2005-2015). RESULTS: Twenty cases of BCG adverse reactions were notified during the study period. Actually, 80% of the patients presented local adverse reactions. The outcome was good in all the followed patients. The rate of disseminated BCG disease was 20%. Biological tests of immunity showed a primary immunodeficiency in three cases, whereas the outcome was fatal in two cases. CONCLUSION: BCG vaccine adverse reactions range from mild to severe. However, the management of benign local reactions remains unclear. Disseminated BCG disease must alert clinicians to the possibility of a primary immunodeficiency.

Malignancy in a retrospective cohort of 17 patients with Dermatomyositis or Polymyositis in southern Tunisia.

INTRODUCTION: The prognosis of dermatomyositis (DM)/ polymyositis (PM) in adults is partly related to their association with neoplasia. The aim of our study was to report the epidemiologic, clinical, paraclinical, therapeutic and evolutionary aspects of DM associated with malignancy in patients from Sfax, south eastern of Tunisia. METHODS: A retrospective cohort study of patients with DM or PM admitted in Dermatology and Internal Medicine Departments of Hedi Chaker University Hospital of Sfax between 1996 and 2015. Cases of DM or PM associated with malignancy were retained. RESULTS: Seventeen cases (13.5%) of DM or PM associated with malignancy were noted. Fourteen patients had DM and 3 patients had PM. The Sex ratio M / F was 0.3 and the mean age at diagnosis was 56.5 years. In DM patients, malignancy preceded the myositis in 64.2% of cases. In PM patients, only one patient was known to have breast cancer and the myositis revealed the cancer for 2 others. Treatment consisted of corticosteroids associated with methotrexate in 4 cases. Outcome was fatal in 5 cases (29.4%), due to the underlying cancer in 3 cases. Swallowing disorders related to DM/PM were responsible for death in 2 cases. CONCLUSION: There are no specific clinical or biological features in paraneoplastic DM. In our series, breast neoplasm represented the first cancer associated with DM. Cancers of nasopharynx, colon and urinary tract had the second position.

[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.

[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.

Congenital hemangioma.

Congenital hemangiomas (CHs) are fully developed hemangiomas that are present at birth. There are 2 possible types: rapidly involuting CHs (RICHs) and noninvoluting CHs (NICHs). We conducted a retrospective study (2008-2012) of 6 patients (2 females, 4 males) with CHs (mean age, 16 days). We analyzed the epidemiology, clinical characteristics, and clinical outcome of CHs over this 5-year period.

[Ocular manifestations of pseudoxanthoma elasticum]. / Atteinte oculaire au cours du pseudoxanthome élastique.

BACKGROUND: Pseudoxanthoma elasticum (PXE) is a hereditary disease characterized by skin, ocular, and cardiovascular lesions. Its prognosis depends mainly on the ocular and vascular lesions. METHODS: This study included 11 patients with PXE. All patients had an ophthalmologic examination. RESULTS: All patients had ocular lesions. Seven (63%) had angioid streaks and two, macular lesions. One patient had bilateral intrapapillary drusen (of the optic nerve head). CONCLUSION: Ocular lesions in PXE had substantial diagnostic value. Ocular complications affect functional prognosis. These patients must undergo routine ophthalmologic examinations to look for ocular manifestations and their complications.

[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.

[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.

[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.

Cowden syndrome.

BACKGROUND: Cowden syndrome is a rare genodermatosis charactarized by presence of multiple hamartomas. The aim of the study was to specify the clinical, therapeutic and prognostic aspects of Cowden syndrome. CASES REPORT: Our study included 4 patients with Cowden syndrome, 2 males and 2 females between 14 and 46 years old. Clinical examination of the skin revealed facials papules (4 cases), acral keratosis (1 case), translucent keratotic papules (2 cases). Oral examination revealed papules (4 cases), papillomatosis (4 cases), gingival hypertrophy (4 cases) and scrotal tongue (2 cases). Investigations revealed thyroid lesions (2 cases), fibrocystic disease and lipoma of the breast in 1 case, "glycogenic acanthosis" (1 case), macrocephaly (2 cases), dysmorphic face (1 case) and lichen nitidus (1 case). Oral etretinate and acitretine were temporary efficient in 2 patients. Topical treatment with tretinoin lotion resulted in some improvement in cutaneous, but not mucosal lesions in one patient. No cancer was revealed. CONCLUSION: The pathognomonic mucocutaneous lesions were found in all patients. However, no degenerative lesions have been revealed. A new association of Cowden syndrome with lichen nitidus was found. Treatment with oral retinoids was efficient on cutaneous lesions.
