Profile of leprosy in children under 15 years of age monitored in a Brazilian referral center (2004-2012).

Leprosy in children under 15 years of age is a serious public health problem. In this retrospective case series conducted in a Brazilian reference center (2004-2012), we found 18 cases with a mean age of 10.0±3.6 years of age and 16.6% between 0-5 years of age. Almost 56% of the cases were female, with a median time between the first symptoms and diagnosis of 11 months (4-24); 77.8% reported household contact with leprosy patients. Upon hospital admission, 66.7% presented mostly skin symptoms, while 27.8% presented a degree 2 disability. Most were classified as multibacillary (66.7%). Half of the sample developed a reaction (predominantly type 1) during the follow-up period, while 22.2% developed a late disability.

Clinical and pathological melanoma differences in young and old people / Diferenças clínicas e patológicas do melanoma em jovens e idosos

Background: Melanoma is often misdiagnosed in older people. Some clinical and histopathological features seem to differ according to age. Objectives: This case series aimed to identify clinicopathological differences of melanoma between older and younger patients. Methods: We identified all incident melanomas diagnosed in a dermatology outpatients unit from January/2007 to December/2014. Data were collected from medical records and pathology registries. RESULTS: We included 62 patients (mean age of 62.1 ± 4.2 years), with a median Breslow thickness of 4 mm (1.2 − 6.5). While men were majority in the older group, women prevailed between younger counterparts (p = 0.02). Multivariate analysis identified history of chronic sun exposure, multiple naevi, skin phototypes 1 and 2, in situ melanoma and the presence of another skin tumour to be correlated with age. In a logistic regression model, the presence of chronic sun exposure and nodular subtype were found to influence age. Major limitations include those inherent to cross ­sectional design, including selection and information biases, the lack of confounding factors analysis (including survival and prognosis), and the sample size. Conclusions: On this case series, melanoma seems to be more frequent in older men and in elders with chronic sun exposure; age was found to be significantly related to nodular subtype and chronic sun exposure.

Introdução: O melanoma é frequentemente diagnosticado de modo tardio em pessoas idosas. Algumas características clínicas e histopatológicas parecem diferir de acordo com a idade. Objetivos: Este estudo de série de casos tem por objetivo identificar as diferenças clínico­patológicas do melanoma entre pacientes idosos e jovens. Métodos: Identificaram­se todos os casos incidentes de melanoma diagnosticados em uma unidade ambulatorial de dermatologia de janeiro de 2007 a dezembro de 2014. Os dados foram coletados a partir da revisão dos prontuários médicos e registros do laboratório de patologia. Resultados: Foram incluídos 62 pacientes, com uma média etária de 62,1 ± 4,2 anos, e tumores com mediana de espessura de Breslow de 4 mm (1,2 − 6,5). Enquanto os homens foram maioria no grupo idoso, as mulheres prevaleceram entre os pacientes jovens (p = 0,02). Análise multivariada identificou que a exposição crônica ao sol, presença de múltiplos nevos, fototipos baixos, melanoma in situ e antecedentes de neoplasias cutâneas correlacionaram­se com a idade. Modelo de regressão múltipla confirmou que a exposição ao sol e o tipo nodular influenciam a idade. Conclusões: O melanoma foi mais frequente nesta amostra em homens idosos com exposição crônica ao sol; a idade correlacionou­se significativamente com o tipo nodular e exposição ao sol.

Schamberg's disease: case report with therapeutic success by using colchicine.

Pigmented purpuric dermatoses (PPD) include a spectrum of diseases with different clinical aspects, but with similar histopathological features. Specific clinical findings allow the division of PPD in variants. Schamberg's disease is the most common. Treatment is sometimes ineffective and recurrences are common. There are reports of patients who responded well to the use of colchicine. We report the case of a 32-year-old woman, previously healthy, with a history of onset of asymptomatic lesions in legs. She presented purpuric skin eruptions and brownish stains diffusely distributed in the lower limbs. Biopsy was compatible with PPD. We decided for the introduction of colchicine, with good clinical response. The patient has been followed on outpatient basis for ten months without recurrence.

Impact of drug therapy on brachioradial pruritus.

Few studies have described therapeutic options in brachioradial pruritus. We describe a cross-sectional study of brachioradial pruritus patients treated in an outpatient unit. We reviewed medical records and interviewed brachioradial pruritus patients without indication for decompressive surgery, in order to access the perceptions of intensity of pruritus prior to treatment and response to therapy. We found that antidepressants and anticonvulsants were the most frequently prescribed drugs. Best reductions in pruritus were associated with its highest intensities prior to treatment, and with longer periods of therapy.

Clinical, epidemiological and therapeutic profile of patients with brachioradial pruritus in a reference service in dermatology.

This is a cross-sectional study, conducted from May to November/2014, in a dermatology reference unit, through review of medical records and interviews. In a sample of 49 patients with brachioradial pruritus, we observed higher prevalence of Caucasian (81.6%) and women (73.5 %), with a mean age of 56.1 years. Pruritus occurred in the topography of brachioradialis muscle in 87.8% of cases; 59.2% of the sample reported worsening of pruritus with sun exposure; the mean intensity of this symptom before treatment was 8.63. Therapy effectiveness was described as "very good/good" in 79.2% of cases, and for 55.3% relapses were categorized as "uncommon".

Factors related to blood pressure control in a prospective cohort of hypertensive outpatients / Fatores relacionados ao controle da pressão arterial em coorte prospectiva de pacientes hipertensos ambulatoriais

Previous studies have reported a controversial relationship between inadequate blood pressure control and predictor variables. Current prospective cohort study analyzes the interference of age, gender, diabetes and medication adherence in the control of blood pressure of hypertensive outpatients. Patients were interviewed under blind conditions to determine medication adherence, and clinical variables assessment were standardized. Univariate analysis of variance identified the variables correlated to blood pressure control at the end of the follow-up period. Missing data were excluded from analysis. After adjusting for confounders with univariate analysis, the association between the outcome (BP control rate) with significant factors and the calculated adjusted odds ratios (OR) and their 95% CI was analyzed by logistic regression. No interference by age or medication adherence in blood pressure control was reported. In fact, the higher the number of medications in use, the greater were the chances of having blood pressure control in disorder. Females are associated with a 3.1 increase in odds ratio of poor blood pressure control. Compared with non-diabetic hypertensive patients, hypertensive diabetic ones had a lower chance of poor blood pressure control.

Estudos anteriores encontraram relações controversas entre o inadequado controle da pressão arterial e variáveis preditoras. Nesta coorte prospectiva, objetivamos analisar a interferência da idade, do gênero, da presença de diabetes e da adesão à medicação no controle da pressão arterial em pacientes hipertensos ambulatoriais. Os pacientes foram entrevistados sob condições de cegamento dos avaliadores na mensuração da adesão à medicação, e a metodologia de avaliação das variáveis clínicas foi padronizada. Uma análise univariada identificou quais variáveis correlacionaram-se com o controle da pressão arterial ao final do período de seguimento. Dados faltantes foram excluídos da análise. Após ajuste para variáveis de confusão por meio da análise univariada, analisamos as associações entre o desfecho (controle da pressão arterial) e variáveis preditoras, e calculamos o odds ratio ajustado e seu intervalo de confiança de 95%, utilizando regressão logística. Não encontramos interferência da idade ou aderência aos medicamentos no controle tensional. Constatamos que, quanto maior o número de medicamentos em uso, maiores as chances de apresentar controle tensional fora das metas. O gênero feminino associou-se com o aumento de 3,1 vezes na chance de mau controle da pressão arterial. Comparados com pacientes hipertensos não diabéticos, os hipertensos diabéticos tiveram menores chances de apresentar mau controle tensional.

Mycobacterium peregrinum Skin Infection: Case Report.

BACKGROUND: Mycobacterium peregrinum is a rapidly growing mycobacterium (RGM) that rarely causes skin infections. The correct identification of the specific RGM infecting the skin will enhance therapeutic success. OBJECTIVE: To highlight the importance of rapid and precise identification of the Mycobacterium involved in skin infections in order to enhance therapeutic success. METHODS: We describe an RGM skin infection in an immunocompetent patient. RESULTS: Classic methods (biochemical tests and culture) of RGM identification are time-consuming, and the histopathological features are not specific. Some molecular methods are reliable but expensive. The PRAhsp-65 is a simple procedure that is helpful in identifying the specific agent of an RGM. CONCLUSION: Although skin infections caused by M peregrinum are rare, they represent a substantial clinical challenge. Specific and more effective treatment options depend on the development of precise and rapid methods for identifying mycobacterial species.

Surgical treatment of type I neuritis in a teenage boy with borderline tuberculoid leprosy.

Exacerbation of the immune response against Mycobacterium leprae can lead to neuritis, which is commonly treated via immunosuppression with corticosteroids. Early neurolysis may be performed concurrently, especially in young patients with a risk of functional sequelae. We report the case of a young patient experienced intense pain in the left elbow one year after the treatment of tuberculoid-tuberculoid leprosy. The pain was associated with paresthesias in the ulnar edge and left ulnar claw. After evaluation, the diagnosis was changed to borderline tuberculoid leprosy accompanied with neuritis of the left ulnar nerve. Early neurolysis resulted in rapid reduction of the pain and recovery of motor function.

Characterization of sporotrichosis cases treated in a dermatologic teaching unit in the state of São Paulo - Brazil, 2003 - 2013.

We conducted a transversal retrospective study with secondary data collection from 25 cases of sporotrichosis, treated at a teaching unit in inner São Paulo (Brazil), between the years 2003-2013. We found that the prevalence was higher in men (72%), rural workers (44%) and those living in rural areas (60%), with an average age of 42.48 years. The median between the onset of lesions and diagnosis was six weeks. Lesions predominated in the upper limbs (92%), and were classified as lymphocutaneous (80%) and fixed cutaneous (20%) forms. Clinical cure was observed in 62.5% of the cases treated with potassium iodide and 100% of cases treated with itraconazole.

Mycobacterium marinum infection: a case report.

The infection by Mycobacterium marinum in humans is relatively uncommon. When it occurs, it mainly affects the skin, usually with a chronic, indolent and benign evolution. The diagnosis requires a high index of suspicion, and a significant delay may be observed between the first symptoms to the final diagnosis. This present case reports a M. marinum infection in an immunocompetent patient that had a chronic undiagnosed injury on the dominant hand for at least five years. The patient had several medical consultations, without proper suspicion, hampering adequate diagnostic investigation. Histopathology detected tuberculoid granulomas, but showed no acid-fast bacilli. The culture in appropriate medium and the polymerase chain reaction-restriction enzyme analysis (PRA)-hsp65 confirmed the diagnosis. Treatment with clarithromycin (1 g/day) for three months was effective. Although uncommon, this infection is a contact zoonosis. Therefore, it is important for clinicians to be aware of this diagnosis and properly guide preventable measures to professionals that are in risk group.

Clinical and demographic profile of chromoblastomycosis in a referral service in the midwest of São Paulo state (Brazil).

Chromoblastomycosis is one of the most frequent deep mycoses found in rural populations. This cross-sectional, retrospective and descriptive study was conducted with cases of chromoblastomycosis diagnosed throughout 20 years. A higher prevalence was observed among White male rural workers, with an average age of 59.69 years. Median time between onset of symptoms and diagnosis was 156 months. Lesions were predominantly located on the lower limbs; 34% of cases reported previous trauma. The most common associated symptoms were itching, pain and burning sensation. Mycological examination was positive in 91% of cases and Fonsecaea pedrosoi was the most prevalent etiologic agent.

Quality of life profile and correlated factors in chronic leg ulcer patients in the mid-west of São Paulo State, Brazil.

BACKGROUND: Chronic leg ulcer may have an impact on patients' quality of life. OBJECTIVES: This study aimed to identify the impact of leg ulcers on patient's quality of life using the Dermatology Life Quality Index and to define the main factors correlated with this perception. METHOD: Cross-sectional, non-probabilistic sampling study. We included patients with chronic leg ulcers being treated for at least 3 months. A sociodemographic and clinical survey was conducted to assess the profile of the ulcers. We administered a screening for depressive symptoms and the Dermatology Life Quality Index. We performed a descriptive statistical analysis, chi-square test and Mann-Whitney test for categorical data, Pearson for numeric variables, and multiple regression for categorical data. RESULTS: Forty-one patients were assessed. Their mean age was 61.78 years. Venous ulcers (48.8%) were the most prevalent. Seventy-three percent of the sample perceived no impact/low impact on quality of life in the past week, and 26.8% perceived moderate/high impact. A multiple regression analysis identified the causes of lesion, pain related to the ulcers, time of onset, and severity of the depressive symptoms as the variables that had an influence on quality of life. CONCLUSIONS: The majority of the sample perceived low or no impact of the condition on the quality of the life. The variables etiology of the lesion (p<0.001), pain related to the ulcers (p=0.001), time of onset (p=0.006), and severity of the depressive symptoms (p<0.001) had an influence on the quality of life, suggesting the need for further studies with more robust designs to confirm the causal relationship between these characteristics and quality of life.
