[Epidemiological and clinical aspects of prurigo in HIV infected patients in Fousseyni N'Daou hospital of Kayes, Mali]. / Aspects Epidemiologiques et Cliniques du Prurigo Chez les Personnes Vivant avec le VIH a L'Hopital Fousseyni N'Daou de Kayes, Mali.

INTRODUCTION: Prurigo is one of the most common dermatological conditions during HIV infection and AIDS. It appears as an immunosuppression marker associated with HIV infection. The study objective was to determine the prevalence of prurigo in people living with the human immunodeficiency virus (PLHIV) in Fousseyni N'Daou Hospital of Kayes, and to describe the socio-demographic aspects of patients and lesions associated with prurigo among PLHIV. METHODS: It was a descriptive cross-sectional study included all cases of HIV infected patients with prurigo in the Dermatology-Venomology Department of Fousseyni N'DAOU Hospital from January 1, 2015 to August 31, 2015. RESULTS: We collected 121 cases of prurigo. The hospital prevalence was 14.5% among PLHIV with 65% Female and the average age was 34.8 years old (SD: 15-81 years). The elementary lesions associated with prurigo were seropapules (40.2%), vesiculo-crusts (13%), excoriated papules (33.3%), lichenified papules (10.8%), and cicatricial lesions (2.7%). The prurigo was generalized in 68.5% of cases and localized in 31.24%. More than half of our patients had weight loss, fever, diarrhea and oral candidiasis in their medical history. Patients were infected with HIV1 in 60.03% and HIV1+ 2 in 24.3%. More than the half of our patients had a CD4 count inferior to 250 cells/mm3 at the time of prurigo diagnosis. CONCLUSION: In our study, prurigo remains a common condition in PLHIV, particularly in patients with low CD4 counts. Early detection and rapid antietroviral therapy can reduce the frequency of prurigo in PLHIV.

INTRODUCTION: Le prurigo est l'une des affections dermatologiques les plus fréquentes au cours de l'infection à VIH et du sida. Il apparait comme un marqueur de l'immunodépression associée à l'infection VIH. L'objectif était de déterminer la prévalence du prurigo chez les personnes vivant avec le virus de l'immunodéficience humaine (PVVIH) à l'hôpital Fousseyni N'Daou de Kayes (HFDK) et décrire le profil sociodémographique des patients et les lésions associées au prurigo chez les PVVIH à HFDK. PATIENTS ET MÉTHODES: Il s'agissait d'une étude transversale descriptive de tous les cas de prurigo chez les PVVIH dans le service de Dermatologie-Vénéréologie de l'hôpital Fousseyni N'DAOU durant la période du 1er janvier 2015 au 31 août 2015. RÉSULTATS: Nous avons colligé 121 cas de prurigo. La prévalence hospitalière a été de 14,5% chez les PVVIH. Le sexe féminin a représenté 65% des cas. L'âge moyen a été de 34,8 ans (extrêmes :15 ­ 81 ans). Les lésions élémentaires associées au prurigo ont été les séropapules (40,2%), vésiculo-croutes (13%), papules excoriés (33,3%), papules lichenifiés (10,8%), lésions cicatricielles (2,7%). La forme généralisée a représenté 68,5% et la forme localisée 31,24%. Plus de la moitié de nos patients avait la notion d'amaigrissement, de fièvre, de diarrhée et des candidoses buccales dans leurs antécédents. Le VIH1 a représenté 60,03% et l'association VIH1 et VIH2 a représenté 24,3% des cas. Plus de la moitié de nos patients avait un taux de CD4 inférieure à 250 cellules/mm3 au moment du diagnostic du prurigo. CONCLUSION: Dans notre étude, le prurigo reste une affection fréquente chez les PVVIH, particulièrement lorsque le taux de CD4 est bas. Un dépistage précoce et le traitement antirétroviral rapide permet de réduire la fréquence du prurigo chez les PVVIH.

Self-healing juvenile cutaneous mucinosis: Clinical and histopathologic findings of 9 patients: The relevance of long-term follow-up.

BACKGROUND: Self-healing juvenile cutaneous mucinosis (SHJCM) is a rare disorder, and its pathogenesis and long-term prognosis are unknown. OBJECTIVE: To elucidate the clinical and histopathologic characteristics, pathogenesis, and outcome in patients with SHJCM. METHODS: Retrospective study of 9 patients with SHCJM. To complement initial findings, data collection forms were sent to the referring physicians. RESULTS: All patients had an acute onset of firm nodules. Of the 9 patients, 6 presented initially with waxy papules on the dorsum of the hands; 5 suffered from periorbital edema, and 6 had a febrile prodrome. Histopathologic assessment of the papules revealed dermal mucin deposition, whereas the nodules showed proliferative fasciitis-like features or nonspecific chronic lobular panniculitis. Laboratory studies elicited evidence of active viral infection in 2 patients (human herpes virus 6 and rotavirus). Seven cases had spontaneous resolution within 6 months, and 2 patients with incomplete resolution showed subsequent transition to fibroblastic rheumatism and an autoinflammatory rheumatologic disease, respectively. LIMITATIONS: This was a retrospective study with incomplete data from referring physicians. CONCLUSIONS: Although spontaneous complete regression is expected, patients with SHJCM need long-term follow-up because of the possible development of dematorheumatolgic conditions. The pathogenetic role of microbial agents deserves further investigation.

A clinical, dermoscopic, and histopathological study of Dermatosis Papulosa Nigra (DPN) - An Indian perspective.

BACKGROUND: Dermatosis papulosa nigra (DPN) is a benign cutaneous condition which commonly occurs in dark-skinned people, especially Asians and African Americans. Owing to its benign nature and rarity, very few studies have been conducted to date, and dermoscopic studies are practically nonexistent. OBJECTIVES: To study the clinical and epidemiological characteristics of patients with dermatosis papulosa nigra (DPN) and to correlate the clinical findings with dermoscopic and histopathological findings in DPN. METHODS: A total of 100 patients attending the Dermatology outpatient department at Father Muller Medical College, Mangalore, India, with clinically diagnosed dermatosis papulosa nigra were included in the study. Histopathology and dermoscopic evaluation of the lesions were done, and the characteristics seen were noted. RESULTS: Earlier onset of lesions was noted in our study, i.e. onset in the 4th decade as compared to the 6th decade in most other studies. A female preponderance, positive family history, history of sun exposure, and involvement of the head and neck were other significant associations. Histopathology revealed an acanthotic variant in all the lesions that were biopsied. The predominant dermoscopic finding was fissures and ridges of the cerebriform pattern followed by comedo-like openings. CONCLUSION: Dermatosis papulosa nigra is a benign unaesthetic condition seen in Fitzpatrick skin types IV-VI. The diagnosis is mainly clinical; however, in a few cases histopathology and dermoscopy aid in differentiating it from other benign and malignant tumors. Dermoscopy, in particular, being a noninvasive investigative moiety is a rapid and accurate diagnostic tool.

Skin diseases among elderly patients attending skin clinic at the Regional Dermatology Training Centre, Northern Tanzania: a cross-sectional study.

BACKGROUND: As global population of the elderly continues to rise, a critical need to provide it with health services, including dermatology, will be significant, especially in developing countries like Tanzania. To adequately meet their dermatologic needs, knowledge of local patterns of skin conditions is vital. This study was aimed to describe the spectrum of skin diseases among elderly patients attending skin clinic at the Regional Dermatology Training Centre (RDTC) in Northern Tanzania. METHODS: A descriptive hospital based cross-sectional study was conducted between January 2013 and April 2013 at RDTC and included all patients aged 55 years and above who consented to be examined. Diagnoses were clinical, diagnostic tests being done only when necessary. Ethical clearance to conduct the study was granted. RESULTS: A total of 142 patients, age ranges 55-99 years, median age of 67.5 years were seen. Eczemas were the leading disease group (43.7%), with unclassified eczemas (33.9%) predominating. Papulosquamous disorders (15.4%) were second with psoriasis (50%) being the leading disease. Infections (11.3% with fungal infections the leading group representing 5.6% of all diseases), tumours (9.8%: Kaposi's sarcoma 4.2%), vascular disorders 9.1% (lymphedema 4.9%), autoimmune disorders 7.7% (connective tissue diseases 4.9%), vitiligo 4.2%, nutritional diseases 2.1% (pellagra 0.7%), urticaria 0.7% and drug reactions 0.7%. CONCLUSIONS: Eczemas are the most common group of disorders among elderly patients presenting at RDTC.

Epidemiology of skin diseases in University of Nigeria Teaching Hospital, Ituku-Ozalla, Enugu State.

Background: Several studies have been carried out to determine the patterns of skin diseases across Nigeria and results have shown changing patterns with the trend reflecting a higher tendency for allergic dermatoses in a majority of these studies. This study was carried out to evaluate the current clinical picture of patients presenting to our clinic. Materials and Methods: A prospective study of new patients seen in the skin clinic of University of Nigeria Teaching Hospital (UNTH), Ituku- Ozalla, between November 2013 and August 2014 was carried out. A total of 387 patients' data was analysed. Data collected on patients' sociodemographic status and diagnosis were entered into SPSS Version 17 and analyzed. Diagnosis was based on clinical findings, laboratory diagnosis including biopsy and histopathology were requested when necessary to make a diagnosis. Results: There were more females 245 (63%) than males 142 (37%). Most of the patients (81.9%) were aged above 16years and the commonest skin disease was infections (29.5%) followed by allergic skin diseases (13.6%). There was a significant difference in levels of income of study participants across gender and females who were engaged in unskilled labour were more likely to earn lower than males. Conclusion: Comparing the study findings with an earlier one from the same center, there is a change in pattern with infections being the most common skin disease. These are largely preventable; public enlightenment campaigns and policies to discourage over the counter purchase of prescription strength corticosteroid creams are highly desirable.

[How I explore scalp and hairin erythemato-squamous disorders]. / Comment j'explore le scalp et la chevelure au cours de dermatoses érythémato-squameuses.

In their early stages, some dermatoses of the scalp such as psoriasis seborrheic dermatitis, tinea capitis and discoid lupus erythematosus are often hardly noticeable to others. However, the eruptions are occasionally severe and extensive. Reaching an adequate diagnosis is of utmost impor¬tance for an adequate healthcare.

A leurs débuts, certaines dermatoses du cuir chevelu telles que le psoriasis, la dermite séborrhéique, une teigne ou le lupus érythémateux discoïde, sont souvent peu discernables par l'entourage. Cependant, ces éruptions sont occasionnelle¬ment sévères et extensives. Obtenir un diagnostic de certitude est un objectif majeur pour une prise en charge adéquate.

Profile of skin biopsies and patterns of skin cancer in a tertiary care center of Western Nepal.

BACKGROUND: Skin biopsy is the method to assist clinicians to make definite dermatological diagnosis which further helps in holistic management. Skin cancers are relatively rare clinical diagnosis in developing countries like Nepal, but the prevalence is on rise. OBJECTIVES: To investigate the profile of skin biopsies and frequencies and pattern of skin cancers in a tertiary care centre of Western Nepal. MATERIALS AND METHODS: The materials consisted of 434 biopsies (1.37%) out of 31,450 OPD visits performed in the Department of Dermatology, Manipal Teaching Hospital, Pokhara, Nepal, during the period of Dec 2011-Nov 2014. Data were collected and analyzed using SPSS-16 with reference to incidence, age, sex, race and clinical and histopathological features. RESULTS: The commonest disorders observed in biopsies were papulosquamous lesions, skin tuberculosis of different types, benign skin tumors, leprosy, collagen and fungal diseases. Viral diseases were rarely seen, probably due to straight forward clinical diagnosis. Dermatological malignancies accounted for 55/434 (12.67%) of biopsies. Skin disorders in general were commoner in females 280/434 (64%), including malignancies 32/55(58.2%). Mean age of patients with skin cancer was 54.5 years. Facilities for proper laboratory investigation of dermatological disorders will improve the quality of life. CONCLUSIONS: The most prevalent lesion in skin biopsies was papulosquamous disorders followed by skin tuberculosis of different types. Dermatological malignancy constituted 55/434 (12.67%) cases. The prevalence of skin malignancy is on rise in Nepalese society probably due to increase in life expectancy and better diagnostic services.

Nevus comedonicus: a case series.

Twelve previously unreported cases of nevus comedonicus are presented. Characteristic closely grouped dilated follicular openings with horny plugs that mimic comedones led to the diagnosis. One patient had nevus comedonicus syndrome and there were cases with atypical locations and unusual complications of this condition. We also highlight clinical associations and therapeutic options.

[ACNE VULGARIS--AETIOLOGY, CLASSIFICATION, TREATMENT]. / TRADZIK POSPOLITY--ETIOLOGIA, KLASYFIKACJA, LECZENIE.

A spotless skin is a rarity. Both women and men have different problems related to the complexion. One of the most common problems is acne, which affects an increasing number of people of all ages. Seborrhea skin areas rich in sebaceous glands, the formation of comedones, inflammation, and scars are characteristic for this disease. The aim of the study was to discuss the causes of acne vulgaris, methods of treatment, and proper care of the skin affected by this problem.

Pattern of pediatric dermatoses at a referral centre.

OBJECTIVE: To determine the pattern of skin disorders seen among children attending a Medical College Hospital, Bangalore METHODS: All children 18 y and below attending the Pediatric Dermatology OPD with skin diseases between the period of January 2011 and June 2011 were included in the study. RESULTS: A total of 1,090 new cases (boys 589; girls 501) with 1,118 dermatoses were recorded during this period. Twenty eight children had more than one dermatoses. Most of the disorders were seen between 5 and 11 y age group. The most common dermatoses was infections and infestations (32.47 %) followed by eczematous eruptions and dermatitis (20.66 %), papulosquamous and related disorders (6.08 %) and pigmentary disorders (5.81 %). Insect bite reactions and papular urticaria formed 5.1 %. Acne was seen in 5.28 % of children followed by urticaria (3.67 %), photodermatoses 2.5 % and genetic disorders (3.04 %). CONCLUSIONS: In the present setting bacterial infections and scabies still remained the most common pediatric dermatoses followed by molluscum contagiosum and atopic dermatitis. Childhood psoriasis contributed to major part of the study among papulosquamous disorders.

[Fibrous papules of the face: a retrospective anatomoclinical study of 283 cases]. / Papules fibreuses du visage: une étude anatomo-clinique rétrospective de 283 cas.

BACKGROUND: Fibrous papules of the face are frequent benign lesions seen in the nasal and perinasal region. Their clinical aspect is indistinct and the histological signs are sometimes mild or possibly misleading in the case of atypical forms. We carried out a retrospective study of 283 fibrous papules diagnosed at our histology laboratory. The goal of this study was to characterize this type of frequent but occasionally unrecognized lesion. PATIENTS AND METHODS: We performed a retrospective study of fibrous papules of the face diagnosed in the dermatopathology laboratory of our dermatology centre between January 2002 and December 2011. The study concerned the clinical information noted in the examination request and the morphological abnormalities seen at optical microscopy. An immunohistological study of factor XIIIa was performed in selected cases. RESULTS: The fibrous papules of the face came from 129 men and 154 women aged between 18 and 90 years (mean: 46 years). Two hundred and thirty-seven (83.7%) lesions were taken from the nasal region and none were taken from anywhere other than the face. The clinically mentioned diagnoses varied. A diagnosis of fibrous papule of the face was stated in 42% of cases, and the main differential diagnoses were nevus (stated in 34% of cases) and basal cell carcinoma (stated in 14% of cases). The fibrous papules were classic in 85.5% of cases. We observed 6 variants of fibrous papule: hypercellular, inflammatory, pleomorphic, pigmented, clear-cell and granular-cell types. Immunohistochemistry of factor XIIIa was positive in all cases except clear-cell fibrous papules. DISCUSSION: This study shows that despite their frequency, these lesions often go unrecognized, since the hypothesis of a fibrous papule of the face was mentioned in fewer than 50% of cases at the time of biopsy. Diagnosis is often made by the histopathologist, who may be misled by some rare types. The principal differential diagnoses are nevus and basal cell carcinoma, thus warranting methodical histological analysis of all pieces.

Etiology and risk factors associated with a pruritic papular eruption in people living with HIV in India.

INTRODUCTION: Papulopruritic eruption (PPE) occurs in people living with HIV in India. Understanding the risk factors associated with this disease may help decrease the prevalence of PPE. METHODS: This study was a case-control study performed at the Government Hospital of Thoracic Medicine, a tertiary care hospital in Chennai, India. Cases included HIV-positive, antiretroviral (ARV) therapy-naïve adults experiencing a pruritic skin eruption for longer than one month, with evidence of multiple papular or nodular lesions and biopsy consistent with arthropod bite. Controls included HIV-positive, ARV-naïve patients without active skin rash. Main outcome measures were CD4 cell count, histology, and environmental exposures. We performed statistical analysis using Epi Info version 3.5.1 and SPSS version 11.0 (SPSS Inc., Chicago, IL). Categorical variables such as gender, urban versus rural residence, occupation, treatment history, CD4 count, use of insect repellents, and environmental exposures were evaluated using the χ(2) test (or the Fisher exact test when an expected value for a category was less than 5). The t-test was used to evaluate differences in age and the duration since HIV diagnosis. The Mann-Whitney test was used to compare non-normally distributed values such as CD4 cell count. A p-value that was less than 0.05 was considered to be statistically significant. RESULTS: Forty-one cases and 149 control subjects were included. Subjects with PPE had significantly lower CD4 cell counts compared to controls (225.5 cells/µL vs. 425 cells/µL; p=0.0001). Sixty-six percent of cases had a CD4 cell count less than 350 cells/µL. PPE cases were less likely to use mosquito repellent techniques (odds ratio 2.81, CI = 1.45-5.45). DISCUSSION: PPE may be an altered and exaggerated immune response to arthropod bites in HIV-positive patients. CD4 cell count is significantly lower in patients with PPE, and therefore it may be considered a qualifying clinical finding for ARV initiation in resource-poor settings. Protective measures against mosquito bites appeared to be important in preventing PPE in subjects at risk.

Prevalence of weathering nodules of the ear in patients treated at the state civil servant's hospital of São Paulo, Brazil.

BACKGROUND: Weathering nodules of the ear are pale yellow, asymptomatic lesions which predominate on the helices of the ears. Although their pathogenesis remains unknown, there is an association with chronic exposure to ultraviolet radiation, age and thermal injuries. Few studies have been conducted to date, and these involved a very small number of patients. OBJECTIVE: Study the prevalence of weathering nodules of the ear in patients treated in the Dermatology Service of the State Civil Servant's Hospital of São Paulo, and evaluate their probable relationship with sun exposure, age and phototypes I and II. METHODS: Four hundred patients older than 20 years of age were examined between July 2008 and December 2008. A questionnaire evaluating age, sex, place of birth, origin, occupation and history of sun exposure was applied. All patients were examined and evaluated for the presence of lesions by only one person. RESULTS: The data showed that 155 (38.8%) patients had a lesion in at least one of the ears. The Chi-Square Test was used for the comparative analysis between the groups of patients with and without lesions. In the group of patients with lesions, 29% were 70 to 79 years old, 78.1% had a history of sun exposure and 45.1% belonged to FITZPATRICK skin phototypes I and II (p<0.05%). CONCLUSION: The findings suggest relevant prevalence, probable association with chronic sun exposure, advanced age and phototypes I and II.
