Nail clipping in onychomycosis.

Onychomycosis is the most prevalent onychopathy and it requires a correct early diagnosis. Currently, the diagnostic gold standard is the association of direct mycological test with culture; however, it shows variable sensitivity. The histopathological examination of the distal nail plate, called clipping, has shown to be an adjuvant in diagnosing onychomycosis. This is an easy-to-perform, relatively cheap examination that is little dependent of the examiner, rapidly provides results, has high sensitivity, and for patients it is painless and harmless.

Laparoscopic antireflux surgery in patients with extra esophageal symptoms related to asthma / A cirurgia antirrefluxo laparoscópica em doentes com sintomas extraesofágicos relacionados à asma

BACKGROUND: Asthma, laryngitis and chronic cough are atypical symptoms of the gastroesophageal reflux disease. AIM: To analyze the efficacy of laparoscopic surgery in the remission of extra-esophageal symptoms in patients with gastroesophageal reflux, related to asthma. METHODS: Were reviewed the medical records of 400 patients with gastroesophageal reflux disease submitted to laparoscopic Nissen fundoplication from 1994 to 2006, and identified 30 patients with extra-esophageal symptoms related to asthma. The variables considered were: gender, age, gastroesophageal symptoms (heartburn, acid reflux and dysphagia), time of reflux disease, treatment with proton pump inhibitor, use of specific medications, treatment and evolution, number of attacks and degree of esophagitis. Data were subjected to statistical analysis, comparing the pre- and post-surgical findings. RESULTS: The comparative analysis before surgery (T1) and six months after surgery (T2) showed a significant reduction on heartburn and reflux symptoms. Apart from that, there was a significant difference between the patients with daily crises of asthma (T1 versus T2, 45.83% to 16.67%, p=0.0002) and continuous crises (T1, 41.67% versus T2, 8.33%, p=0.0002). CONCLUSION: Laparoscopic Nissen fundoplication was effective in improving symptoms that are typical of reflux disease and clinical manifestations of asthma. .

RACIONAL: A asma, a laringite e a tosse crônica são sintomas atípicos da doença do refluxo gastroesofágico. OBJETIVO: Analisar a eficácia da cirurgia laparoscópica na remissão de sintomas extra-esofágicos em doentes com refluxo gastroesofágico, relacionada com a asma. MÉTODOS: Foram revisados ​​os prontuários de 400 doentes com doença do refluxo gastroesofágico submetidos à fundoplicatura a Nissen entre 1994 e 2006 e foram identificados 30 casos com sintomas extra-esofágicos relacionadas à asma. As variáveis ​​consideradas foram: sexo, idade, sintomas gastroesofágicos (azia, refluxo ácido e disfagia), o tempo da doença do refluxo, o tratamento com inibidores da bomba de prótons, o uso de medicamentos específicos, tratamento e a evolução, o número de crises e o grau de esofagite. Os dados foram submetidos à análise estatística, comparando os resultados pré e pós-operatórios. RESULTADOS: A análise comparativa antes da operação (T1) e seis meses após (T2) mostrou redução significativa dos sintomas de azia e refluxo. Além disso, houve diferença significativa entre os doentes com crises diárias de asma (T1 versus T2, 45,83% para 16,67%, p=0,0002) e crises contínuas (T1 41,67% versus T2 8,33%, p=0,0002). CONCLUSÃO: A fundoplicatura à Nissen por via laparoscópica foi eficaz na melhora dos sintomas que são típicos da doença do refluxo e manifestações clínicas da asma, melhorando a qualidade de vida. .

Finger burns caused by concentrated hydrofluoric acid, treated with intra-arterial calcium gluconate infusion: case report / Queimadura digital por ácido fluorídrico concentrado tratada com infusão intra-arterial de gluconato de cálcio: relato de caso

CONTEXT: Hydrofluoric acid (HF) is widely used in industry and at home. Severe lesions can occur after contact with highly concentrated solutions, leading to tissue necrosis and bone destruction. Specific treatment is based on neutralization of fluoride ions with calcium or magnesium solutions. CASE REPORT: A 41-year-old male was seen at the emergency department 35 minutes after skin contact with 70 percent HF, showing whitened swollen lesions on the middle and fourth fingers of his right hand with severe pain starting immediately after contact. 2.5 percent calcium gluconate ointment was applied. Twenty-four hours later, the patient was still in severe pain and the lesions had worsened. Considering the high concentration of the solution, early start of severe pain, lesion characteristics and impossibility of administering calcium gluconate subcutaneously because of the lesion location, the radial artery was catheterized and 2 percent calcium gluconate was administered via infusion pump for 36 hours, until the pain subsided. No adverse effects were seen during the procedure. Ten days later, the lesions were stable, without bone abnormalities on X-rays. Six months later, a complete recovery was seen. CONCLUSIONS: Intra-arterial calcium gluconate might be considered for finger burns caused by concentrated HF. Complete recovery of wounded fingers can be achieved with this technique even if started 24 hours after the exposure. However, controlled clinical trials are needed to confirm the effectiveness and safety of this intervention.

CONTEXTO: Ácido fluorídrico é largamente usado na indústria e no ambiente doméstico. Lesões graves podem ocorrer depois de contato com soluções altamente concentradas levando a necrose tecidual e destruição óssea. O tratamento específico é baseado na neutralização dos íons de flúor com soluções de cálcio ou magnésio. RELATO DE CASO: Homem de 41 anos foi atendido na sala de urgência 35 minutos depois de contato da pele com ácido fluorídrico a 70 por cento, apresentando lesões esbranquiçadas e edemaciadas nos dedos médio e quarto da mão direita com dor intensa que iniciou logo após o contato. Pomada de gluconato de cálcio a 2,5 por cento foi aplicada. Depois de 24 horas, o paciente continuava com dor mais intensa e as lesões haviam piorado. Considerando a concentração da solução, o início precoce da dor intensa, as características das lesões e a impossibilidade de administrar gluconato de cálcio no subcutâneo devido ao local da lesão, foi inserido cateter na artéria radial para infusão de gluconato de cálcio a 2 por cento com bomba de infusão por 36 horas até melhora da dor. Nenhum efeito adverso foi observado durante o procedimento. Dez dias depois as lesões encontravam-se estáveis, sem alterações dos ossos vistas nos raios-X. Seis meses depois houve recuperação completa. CONCLUSÃO: Gluconato de cálcio intra-arterial pode ser considerado em queimaduras digitais por ácido fluorídrico. Recuperação completa dos dedos acometidos pode ser obtida com essa técnica mesmo que iniciada 24 horas após a exposição. Porém, ensaios clínicos controlados são necessários para confirmar a efetividade e a segurança desta intervenção.

[Clinical and laboratory characterization of hypertensive Chagas disease patients without evident heart failure]. / Caracterização clínico-laboratorial de chagásicos hipertensos sem insuficiência cardíaca manifesta.

This study evaluated the characteristics of 125 Chagas disease patients aged > 25 years or over who were attended at the Clinical Hospital of the State University of Campinas, State of São Paulo. Arterial pressure, age, gender, skin color, heart disease, body mass index, lipid profile, blood glucose level, alcohol and tobacco dependence, dyslipidemia, diabetes, anxiety disorders and obesity were investigated. It was found that the hypertensive Chagas disease patients were older than the non-hypertensive ones (p = 0.028). Among the hypertensive patients, there were more women (p = 0.015); higher blood glucose, LDL cholesterol and total cholesterol levels (p = 0.005, p = 0.024 and p = 0.017); more diabetics (p = 0.006); and more cardiac damage (p = 0.04) and left ventricular hypertrophy (p = 0.003). Only the age of patients with cardiac damage was shown to be higher (p = 0.003). The hypertensive Chagas disease patients presented clinical and laboratory characteristics that were similar to those of the general hypertensive population. This association may compound the harmful effects on the cardiovascular system.

Caracterização clínico-laboratorial de chagásicos hipertensos sem insuficiência cardíaca manifesta / Clinical and laboratory characterization of hypertensive Chagas’ disease patients without evident heart failure

Este estudo avaliou as características de 125 chagásicos, > 25 anos, atendidos no Hospital de Clínicas da Universidade Estadual de Campinas, SP, considerando-se: pressão arterial, idade, gênero, cor, cardiopatia, índice de massa corporal, perfil lipídico, glicemia, etilismo, tabagismo, dislipidemia, diabetes, distúrbio de ansiedade e obesidade. Apresentavam hipertensão arterial 69 (55,2 por cento) pacientes. Verificou-se que os chagásicos hipertensos eram mais idosos que os não hipertensos (p = 0,028). Entre os hipertensos havia: mais mulheres (p = 0,015); níveis mais elevados de glicemia, LDL-colesterol e colesterol total (p = 0,005; p = 0,024; p = 0,017); mais diabéticos (p = 0,006), dano cardíaco (p = 0,04) e sobrecarga ventricular esquerda (p = 0,003). Apenas a idade mostrou-se mais elevada nos pacientes com dano cardíaco (p = 0,003). Os chagásicos hipertensos apresentaram características clínico-laboratoriais semelhantes à população hipertensa, em geral. Dessa associação pode haver somatória de efeitos deletérios para o aparelho cardiovascular.
