Hyperhidrosis: prevalence and impact on quality of life / Hiperidrose: prevalência e impacto na qualidade de vida

ABSTRACT Objective: To determine the prevalence of primary hyperhidrosis in the city of Botucatu, Brazil, and to evaluate how this disorder affects the quality of life in those suffering from it. Methods: A population survey was conducted in order to identify cases of hyperhidrosis among residents in the urban area of the city, selected by systematic cluster sampling. In accordance with the census maps of the city, the sample size should be at least 4,033 participants. Ten interviewers applied a questionnaire that evaluated the presence of excessive sweating and invited the subjects who reported hyperhidrosis to be evaluated by a physician in order to confirm the diagnosis. Results: A total of 4,133 residents, in 1,351 households, were surveyed. Excessive sweating was reported by 85 residents (prevalence = 2.07%), of whom 51 (60%) were female. Of those 85 respondents, 51 (60%) agreed to undergo medical evaluation to confirm the diagnosis and only 23 (45%) were diagnosed with primary hyperhidrosis (prevalence = 0.93%). Of the 23 subjects diagnosed with primary hyperhidrosis, 11 (48%) reported poor or very poor quality of life. Conclusions: Although the prevalence of self-reported excessive sweating was greater than 2%, the actual prevalence of primary hyperhidrosis in our sample was 0.93% and nearly 50% of the respondents with primary hyperhidrosis reported impaired quality of life.

RESUMO Objetivo: Estabelecer a prevalência de hiperidrose primária no município de Botucatu (SP) e avaliar como o transtorno afeta a qualidade de vida dos seus portadores. Métodos: Foi realizado um levantamento populacional para identificar os casos de hiperidrose em moradores da região urbana da cidade, selecionados por amostragem sistemática de conglomerados. O número amostral de 4.033 participantes foi calculado usando os mapas censitários do município. Dez entrevistadores aplicaram um questionário que avaliou a presença de transpiração excessiva e convidaram os sujeitos que referiram hiperidrose para uma entrevista com um médico para a confirmação do diagnóstico. Resultados: Foram pesquisados 1.351 domicílios, com 4.133 moradores. Desses, 85 queixaram-se de sudorese excessiva (prevalência = 2,07%), sendo 51 (60%) do gênero feminino. Dos 85 indivíduos, 51 (60%) concordaram receber avaliação médica para confirmar o diagnóstico, e apenas 23 (45%) apresentaram hiperidrose primária (prevalência = 0,93%). Dos 23 indivíduos diagnosticados com hiperidrose primária, 11 (48%) referiram qualidade de vida ruim ou muito ruim. Conclusões: Embora as queixas de transpiração excessiva tenham sido superiores a 2%, a prevalência real de hiperidrose primária em nossa amostra foi de 0,93% e o distúrbio afetava a qualidade de vida em quase 50% dos indivíduos.

Endobronchial solitary fibrous tumor

Solitary fibrous tumor (SFT) is a mesenchymal neoplasm that appears primarily in the pleura and rarely in intrapulmonary or endobronchial topography. The authors report the case of a 47-year-old woman who presented obstructive respiratory symptoms for 4 years. The chest computed tomography and bronchoscopy showed an obstructive polypoid lesion located between the trachea and the left main bronchus associated with distal atelectasis of the left lung. A resection of the lesion was performed and, macroscopically, the mass was oval, encapsulated, and firm, measuring 2.3 × 1.7 × 1.5 cm. Histology revealed low-grade mesenchymal spindle cell neoplasm, with alternating cellularity, myxoid areas, and mature adipose tissue outbreaks, as well as blood vessels with irregular walls. The immunohistochemical study was positive for CD34, CD99, and BCL2. The diagnosis was SFT in an unusual topography. The patient's symptoms remitted after tumor excision, and no systemic problems were evident. SFTs primarily affect adults and often follow a benign course; however, their behavior is unpredictable. The presence of necrosis and mitotic activity may portend a poor prognosis. Endobronchial SFTs are rare but should be evaluated and monitored similar to SFTs at other sites, with a long-term follow-up

Respiratory immunohistochemical study in rats exposed to cigarette smoke and alcohol

PURPOSE: To investigate the effects of exposure to cigarette and alcohol on immunohistochemical disorders caused by these attacks to respiratory system of rats. METHODS: Sixty male Wistar rats in four groups: control, cigarette smoke, alcohol and cigarette smoke + alcohol during 260 days. Immunohistochemistry was performed by researching survivin and protein P53 expressions and apoptotic index in parenchymal lung and trachea using TUNEL technique. RESULTS: There was body growth impairment in all experimental groups. Both smoker groups animals had higher trachea survivin expression and bronchial higher apoptotic index. The trachea apoptotic index was also higher in the cigarette smoke group as well as in the alveoli in the cigarette smoke + alcohol group. The three experimental groups showed negative immunoexpression for P53. CONCLUSIONS: this model resulted in immunohistochemical changes caused mainly by exposure to cigarette smoke. There was a synergistic action between alcohol and tobacco in the growth impairment in animals as well as in the cellular apoptotic index. The positive immunoexpression for tracheal survivin in animals from both groups exposed to tobacco smoke and associated with a negative P53 immunoexpression suggests that despite the aggression, carcinogenesis has not happened yet. In addition, the bronchial higher apoptotic index in smokers may be responsible for emphysema. .

Congenital lobar emphysema: 30-year case series in two university hospitals / Enfisema lobar congenito: serie de casos de 30 anos em dois hospitais universitarios

OBJECTIVE: To review the cases of patients with congenital lobar emphysema (CLE) submitted to surgical treatment at two university hospitals over a 30-year period. METHODS: We reviewed the medical records of children with CLE undergoing surgical treatment between 1979 and 2009 at the Botucatu School of Medicine Hospital das Clínicas or the Mogi das Cruzes University Hospital. We analyzed data regarding symptoms, physical examination, radiographic findings, diagnosis, surgical treatment, and postoperative follow-up. RESULTS: During the period studied, 20 children with CLE underwent surgery. The mean age at the time of surgery was 6.9 months (range, 9 days to 4 years). All of the cases presented with symptoms at birth or during the first months of life. In all cases, chest X-rays were useful in defining the diagnosis. In cases of moderate respiratory distress, chest CT facilitated the diagnosis. One patient with severe respiratory distress was misdiagnosed with hypertensive pneumothorax and underwent chest tube drainage. Only patients with moderate respiratory distress were submitted to bronchoscopy, which revealed no tracheobronchial abnormalities. The surgical approach was lateral muscle-sparing thoracotomy. The left upper and middle lobes were the most often affected, followed by the right upper lobe. Lobectomy was performed in 18 cases, whereas bilobectomy was performed in 2 (together with bronchogenic cyst resection in 1 of those). No postoperative complications were observed. Postoperative ...

OBJETIVO: Revisar os casos de enfisema lobar congênito (ELC) operados nos últimos 30 anos em dois hospitais universitários. MÉTODOS: Foram revistos os prontuários médicos das crianças com ELC operadas no Hospital das Clínicas da Faculdade de Medicina de Botucatu e no Hospital da Universidade de Mogi das Cruzes entre 1979 e 2009. Dados sobre sintomas, exame físico, achados radiológicos, diagnóstico, tratamento cirúrgico e seguimento pós-operatório mediato e tardio foram analisados. RESULTADOS: Durante o período estudado, 20 crianças com ELC foram submetidas a tratamento cirúrgico. A média de idade dos pacientes no momento da cirurgia foi 6,9 meses (variação, 9 dias a 4 anos). Todos os casos apresentaram sintomas ao nascimento ou nos primeiros meses de vida. Em todos os casos, a radiografia simples de tórax foi importante na definição do diagnóstico. Em casos de dificuldade respiratória moderada, a TC de tórax auxiliou no diagnóstico. Um paciente com desconforto respiratório grave foi diagnosticado erroneamente com pneumotórax hipertensivo e submetido a drenagem torácica. A broncoscopia só foi realizada nos pacientes com dificuldade respiratória moderada e não foram encontrados sinais de anomalias traqueobrônquicas. A abordagem cirúrgica foi realizada através de toracotomia lateral poupadora de músculo. O lobo superior esquerdo e o lobo médio ...

Lung morphology and growth of rats exposed to tobacco smoke and alcohol / Estudo morfológico dos pulmões e crescimento de ratos expostos à fumaça do cigarro e ao álcool

PURPOSE: Investigate the morphological effects of chronic exposure to tobacco smoke inhalation and alcohol consumption on the lungs and on the growth of rats. METHODS: Sixty male Wistar rats were divided into four groups: control, tobacco, alcohol, tobacco + alcohol, for a period of study 260 days. Morphological analysis was conducted by optical and electron microscopy. Rat growth was investigated by measuring the snout-anus length, body mass index and body weight. RESULTS: The three groups exposed to the drugs presented lower growth and lower weight than the control group. The percentages of alveolitis, bronchiolitis and the mean alveolar diameter were greater, particularly in the groups exposed to tobacco smoke, but were not significantly different from the control group. Electron microscopy revealed more intense apoptotic and degenerative lesions in the smoking group, while degenerative lesions in the lamellar bodies were more intense with the association of both drugs. CONCLUSIONS: This experimental model showed morphological alterations observed by electron microscopy, principally due to tobacco smoke exposure. Alcohol and tobacco hindered the growth of rats, such that tobacco showed a greater effect on body length and alcohol on body weight.

OBJETIVO: Investigar os efeitos morfológicos da exposição crônica à inalação de fumaça do tabaco e o do consumo de álcool nos pulmões e no crescimento de ratos. MÉTODOS: Sessenta ratos Wistar machos foram distribuídos em quatro grupos: controle, tabaco, álcool e tabaco + álcool, e acompanhados por um período de 260 dias. No final do periodo foi realizada análise morfológica dos pulmões por microscopia óptica e eletrônica. O crescimento dos ratos foi investigado através da medição do comprimento focinho-ânus, peso corporal e índice de massa corporal. RESULTADOS: Os três grupos expostos às drogas apresentaram peso e comprimento significativamente menores que os do grupo controle. As percentagens de bronquiolite e alveolite, e o diâmetro alveolar médio foram maiores nos grupos expostos à fumaça do tabaco, mas sem significancia estatística quando comparadas ao grupo controle. A microscopia eletrônica revelou apoptose mais intensa e lesões degenerativas no grupo de fumantes, enquanto lesões degenerativas nos corpos lamelares foram mais intensas com a associação de ambas as drogas. CONCLUSÕES: Este modelo experimental mostrou alterações morfológicas observadas por microscopia eletrônica, principalmente devido à exposição ao tabaco. Tanto o alcool como o tabaco prejudicaram o crescimento dos animais, o tabaco mostrando um efeito maior sobre o comprimento e o álcool sobre o peso corporal.

Síndrome do desfiladeiro torácico - ressecção de costela cervical por videotoracoscopia / Thoracic outlet syndrome - cervical rib resection through videothoracoscopic surgery

A base do tratamento cirúrgico da Síndrome do Desfiladeiro Torácico (SDT) é a ressecção da primeira costela, podendo associar-se à escalenectomia ou ainda à ressecção de costela cervical. Esta última é feita tradicionalmente por meio de um acesso supraclavicular ou mesmo axilar, o qual é tecnicamente mais trabalhoso. Pode ser realizada também por meio de acesso paraescapular. Embora tecnicamente atrativa e associada à menor invasividade e maior segurança, com ótimo resultado estético, a ressecção da primeira costela torácica, por intermédio de cirurgia videoassistida transaxilar ou pela técnica videotoracoscópica, é pouco relatada na literatura, e nenhuma referência foi encontrada sobre ressecção de costela cervical mediante essa técnica. Neste artigo, apresentamos essa inovação cirúrgica realizada com sucesso para ressecção de costela cervical em duas pacientes.

The basis of Thoracic Outlet Syndrome (TOS) surgical treatment is the first rib resection and may be associated with scalenectomy or cervical rib resection. The latter is traditionally done through a supraclavicular or axillary access, which is the most technically challenging. It can also be achieved through parascapular access. Although technically attractive and associated with less invasiveness and increased security, with excellent aesthetic results, the first thoracic rib resection via video-assisted transaxillary surgery or videothoracoscopic technique is seldom reported in the literature, and no reference was found on cervical rib resection through this technique. In this article, we introduced this innovation successfully performed for surgical cervical rib resection in two patients.

Orientar os pacientes quanto à patologia e suas prováveis formas de tratamento e avaliar a qualidade de vida relacionada à HP. Foi realizado um inquérito populacional para identificar os casos de hiperidrose em indivíduos maiores de cinco anos, moradores na zona urbana da cidade de Botucatu, localizados por intermédio de amostragem sistemática de conglomerados. Foi calculado um número amostral de 4.033 participantes, utilizando-se os mapas censitários da cidade; a seguir, foram sorteadas quadras de cada setor para obter-se os domicílios. Dez entrevistadores previamente treinados foram responsáveis por aplicar um questionário que avaliou a presença de sudorese excessiva. Após análise dos questionários os indivíduos que referiram hiperidrose foram entrevistados por um médico para confirmação ou não do diagnóstico. Todos os indivíduos foram orientados e, caso houvesse indicação, o tratamento foi oferecido. Foram visitados 1.351 domicílios totalizando 4.113 moradores, sendo 2.150 (52,3%) do gênero feminino. A idade variou de cinco a 97 anos (média ± DP = 38,3 ± 21,2). Oitenta e cinco indivíduos (2,07%) queixavam-se de suor excessivo, sendo 51 (60%) do gênero feminino com idade variando de cinco a 72 anos (média ± DP = 33,9 ± 17,3). O efeito psicossocial mais frequente devido à sudorese foi o constrangimento, e o fator predisponente mais frequente foi o nervosismo. Cinquenta e um indivíduos (60%) concordaram em receber a visita médica para a confirmação do diagnóstico...

The hyperhidrosis is characterized by the excessive sweating and its etiology can be primary or idiopathic (PH) and secondary (SH) to other diseases but its prevalence is not well defined. To establish the PH prevalence in the city of Botucatu- Brazil. To perform orientation related to the pathology and its probable forms of treatment and evaluate the quality of life related to PH. A population survey was performed in order to identify the cases of hyperhidrosis in individuals aged over five years, residents in Botucatu urban area and selected by cluster systematic sampling. A sample number of 4,033 participants was calculated using the Census maps from the city and a selection of blocks in each sector was carried out in order to obtain the households. Ten previously trained interviewers were responsible for applying a questionnaire that evaluated the presence of excessive sweating. After the questionnaires analysis the individuals that referred hyperhidrosis were interviewed by a physician in order to confirm the diagnosis. All subjects were instructed and the treatment was offered in case of indication. 1,351 households were surveyed with a total of 4,113 residents, in which 2,150 (52.3%) were female.

Fifty-one individuals (60%) agreed to receive medical evaluation in order to confirm the diagnosis. Twenty-three (45%) had PH (0.93% prevalence), 15 (29.4%) had SH caused by obesity as well as menopause or thyroid disorder and 13 (25.5%) individuals had normal sweating...

Intrapleural analgesia after endoscopic thoracic sympathectomy / Analgesia intrapleural após simpatectomia videotoracoscópica

PURPOSE: To compare analgesia traditionally used for thoracic sympathectomy to intrapleural ropivacaine injection in two different doses. METHODS: Twenty-four patients were divided into three similar groups, and all of them received intravenous dipyrone. Group A received intravenous tramadol and intrapleural injection of saline solution. Group B received intrapleural injection of 0.33 percent ropivacaine, and Group C 0.5 percent ropivacaine. The following aspects were analyzed: inspiratory capacity, respiratory rate and pain. Pain was evaluated in the immediate postoperative period by means of the visual analog scale and over a one-week period. RESULTS: In Groups A and B, reduced inspiratory capacity was observed in the postoperative period. In the first postoperative 12 hours, only 12.5 percent of the patients in Groups B and C showed intense pain as compared to 25 percent in Group A. In the subsequent week, only one patient in Group A showed mild pain while the remainder reported intense pain. In Group B, half of the patients showed intense pain, and in Group C, only one presented intense pain. CONCLUSION: Intrapleural analgesia with ropivacaine resulted in less pain in the late postoperative period with better analgesic outcomes in higher doses, providing a better ventilatory pattern.

OBJETIVO: Comparar a analgesia tradicionalmente utilizada para simpatectomia videotoracoscópica à injeção intrapleural de ropivacaína em duas doses diferentes. MÉTODOS: Vinte e quatro pacientes foram distribuídos em três grupos semelhantes, e todos eles receberam dipirona endovenosa. O grupo A recebeu tramadol endovenoso e injeção intrapleural de solução salina. O grupo B recebeu injeção intrapleural de ropivacaína a 0,33 por cento, e Grupo C ropivacaína a 0,5 por cento. Os aspectos analisados foram: capacidade inspiratória, freqüência respiratória e dor. A dor foi avaliada no período pós-operatório por meio da escala visual analógica e durante o período de uma semana. RESULTADOS: Nos grupos A e B, a redução da capacidade inspiratória foi observada no período pós-operatório. Nas primeiras 12 horas de pós-operatório, apenas 12,5 por cento dos pacientes nos grupos B e C apresentaram dor intensa em comparação a 25 por cento no Grupo A. Na semana seguinte, apenas um paciente do grupo A apresentou dor leve, enquanto o restante relatou dor intensa. No Grupo B, metade dos pacientes apresentou dor intensa, e no Grupo C, apenas um apresentou intensa dor. CONCLUSÃO: A analgesia intrapleural com ropivacaína resultou em menos dor no pós-operatório tardio com os melhores resultados analgésicos nas doses mais altas, proporcionando um melhor padrão ventilatório.
