ABSTRACT Objective: Diabetes mellitus (DM) is a chronic disease of increasing importance in public health, associated with chronic complications including retinopathy, neuropathy, and kidney, cardiovascular and cerebrovascular disease. This study assessed the impact of strategic DM education actions on glycemic control and prevalence of chronic complications in patients with DM. Subjects and methods: Retrospective, quantitative, cohort study at a diabetes patients association comprised of a multidisciplinary team. In all, 533 individuals with DM were included. Sociodemographic and clinical data were collected using questionnaire and medical records. Of these, 333 patients evaluated for 12 to 24 months, with type 2 DM (T2DM, n = 317) and other types of DM (n = 16), were selected to collect data on retinopathy and diabetes kidney disease (DKD). Results: There was a predominance of elderly individuals, low education level, women, high rate of overweight and obesity, physical inactivity, dietary errors, dyslipidemia, and T2DM. More patients with T2DM versus type 1 DM had optimal glycemic control (46.3% vs. 12.2%, respectively; p < 0.001). The impact of the educational processes was demonstrated by the analysis of the initial and final glycated hemoglobin (HBA1c) levels. There was an increased prevalence of individuals with well-controlled DM during follow-up (prevalence ratio [PR] 2.76, 95%, p = 0.001), along with a significant reduction in retinopathy (PR: 0.679, p = 0.001) and albuminuria (PR: 0.637, 95%, p = 0.002) when these variables were evaluated in well-controlled versus uncontrolled HbA1c groups. Conclusions: A multidisciplinary approach with integration and quality was associated with improvements in DM control and reduced occurrence of chronic DM complications.

FUNDAMENTO: O carcinoma basocelular é o câncer da pele mais comum, compreendendo 75% dos tumores epiteliais malignos. Localiza-se na face e acomete indivíduos brancos, acima de 40 anos de idade, com história de exposição repetitiva à luz solar. OBJETIVO: Descrever o carcinoma basocelular em suas variáveis epidemiológica, clínica e histopatológica. CASUÍSTICA: Realizou-se estudo transversal de 300 pacientes com carcinoma basocelular atendidos no Serviço de Dermatologia do Hospital de Clínicas, no período de 1999 a 2003. Foram preenchidos protocolos com identificação do paciente, história de exposição solar e caracterização do carcinoma basocelular. RESULTADOS: Foram identificadas 447 lesões de carcinoma basocelular nos 300 pacientes estudados, cuja maioria era do sexo feminino (59,3%) e da raça branca (93%), com história de exposição solar (90,3%), apresentando lesão única (74%), predominantemente facial (77% das lesões). O tipo histopatológico mais freqüente foi o nodular (46,3% das lesões), com predomínio do superficial no tronco. CONCLUSÕES: Observou-se predomínio do carcinoma basocelular no sexo feminino, demonstrando a tendência atual desse tumor. A presença de vários tumores sucessivos ou simultâneos em um mesmo paciente salienta a importância de exames periódicos nesses doentes. Não se estabeleceu correlação entre os tipos clínicos e histopatológicos. Confirmou-se que o tipo superficial é mais freqüente no tronco.

BACKGROUND: Basal cell Carcinoma is the most common type of skin cancer and represents 75% of malignant epithelial tumors. It usually occurs on the face of white individuals aged over 40 years, with history of repetitive exposure to sunlight OBJECTIVE: To describe the epidemiological data, clinical presentation and histopathological findings of 300 patients with basal cell carcinoma. CASUISTIC: A cross-sectional study of 300 patients with Basal cell Carcinoma seen at the outpatient Dermatology clinic from 1999 to 2003. Information was obtained on identification, exposure to sunlight and characterization of Basal cell Carcinoma. RESULTS: The pathological examinations confirmed the clinical diagnoses of 447 tumor lesions of 300 patients. Most patients were female (59.3%), white (93%), had exposure to sunlight (90.3%), with a single lesion (74%), involving predominantly the face (77% of the lesions). The most frequent pathological type was nodular carcinoma (46.3% of the lesions) and the superficial type predominated on the trunk. CONCLUSIONS: There was a predominance of female patients showing the current tendency of Basal cell Carcinoma. The presence of several successive or simultaneous tumors in the same patient emphasizes the importance of periodical exams in these patients. No exact correlation between exact clinical and pathological findings was established. The superficial type was confirmed as more frequent on the trunk.

Foram estudados 55 pacientes com a síndrome da imunodeficiência adquirida (Aids), triados ao serviço de Dermatologia, apresentando doenças cutâneo-mucosas, algumas de caráter oportunista. As dermatoses são freqüentes nestes doentes e, às vezes, de difícil diagnóstico pelo caráter atípico das lesões. OBJETIVOS: Analisar a freqüência e apresentação clínica das dermatoses relacionadas à Aids. MÉTODOS: Cinqüenta e cinco pacientes com Aids e lesões tegumentares foram estudados, de modo transversal, no Serviço de Dermatologia da Universidade Federal de Uberlândia, de 1995 a 1997. Foram realizadas biopsias e culturas diversas para elucidação diagnóstica. RESULTADOS: Foram encontradas 116 dermatoses, com predomínio das fúngicas (78%), seguidas pelas virais (40%), eritêmato-escamosas (27%), pápulo-pruríticas (18%), causadas por drogas (10%), neoplásicas (9%) e outras afecções cutâneo-mucosas (7%). A maioria dos pacientes apresentou mais de uma dermatose (67%). CONCLUSÕES: Confirmou-se a maior freqüência de dermatoses fúngicas, seguidas pelas virais, na Aids. Observou-se a necessidade de propedêutica bem elaborada para o diagnóstico preciso das dermatoses, devido à sua apresentação atípica em grande número de doentes. O exame dermatológico e a biopsia das lesões tiveram grande relevância na suspeita do diagnóstico de Aids.

Fifty-five patients with acquired immunodeficiency syndrome (AIDS) seen at the Dermatology outpatient clinic and who had mucocutaneous diseases were studied. These diseases, some of them opportunistic, are common but difficult to diagnose given the atypical features of the lesions. OBJECTIVES: The aim of this study was to analyse the frequency and clinical presentation of dermatoses related to Aids seen at the Dermatology outpatient clinic. METHODS: Fifty-five patients with Aids and mucocutaneous lesions were examined from 1995 to 1997 in a cross-sectional study carried out at the Dermatology outpatient clinic of the Universidade Federal de Uberlândia (Minas Gerais, Brazil). Biopsies and cultures were undertaken for laboratory diagnosis. RESULTS: One hundred sixteen dermatoses were diagnosed. Fungal infections (78%) were the commonest among them, followed by viral infections (40%), papulosquamous disorders (27%), papular eruptions (18%), adverse drug reactions (10 %), tumors (9%) and a variety of others (7%). The majority of the patients (67%) had more than one type of skin disorder. CONCLUSIONS: In agreement with previous literature data fungal and viral infections were confirmed as the most frequent skin disorders in HIV-positive patients. Dermatological examination, laboratory tests and skin biopsy for histopathological study are necessary for appropriate diagnostic investigation of HIV-related mucocutaneous diseases considering that atypical presentation occurs in a large proportion of the patients.
