Objective: This prospective study aimed at investigating predictive factors for compensatory sweating after thoracoscopic sympathectomy. Methods: From 2000 to 2002, 80 patients (53 females and 27 males) underwent thoracoscopic sympathectomy to treat hyperhidrosis. Patient ages ranged from 12 to 56 years, and the mean postoperative follow-up period was 42.51 ± 5.98 months. Patient satisfaction with the results was evaluated through the use of a rating scale. The procedure was performed bilaterally: at the T2 level for facial hyperhidrosis; at the T3-T4 level for axillary hyperhidrosis; and at the T3 level for palmar hyperhidrosis. Results: Post-operatively, 68 patients (85.0%) presented compensatory sweating, which was classified as mild in 23 (33.8%), moderate in 23 (33.8%) and severe in 22 (32.4%). Considering the final surgical results, 70 patients (87.5%) were satisfied with the outcome of the operation, whereas 10 patients (12.5%) were dissatisfied. The level of patient satisfaction varied according to gender, age, body mass index (BMI) and extent of denervation. The compensatory sweating was more severe on the abdomen and back than on the legs. Conclusions: Although compensatory sweating, which is a common adverse effect of sympathectomy, occurred in the majority of cases, the level of patient satisfaction was high. The best candidates for thoracoscopic sympathectomy are young adult women with a BMI ≤ 24.9 kg/m 2 .Keywords: Sympathectomy; Hyperhidrosis; Thoracoscopy; Postoperative complications; Thoracic surgery, video-assisted. ResumoObjetivo: Este estudo prospectivo visou investigar fatores preditivos para a hiperidrose compensatória após a simpatectomia toracoscópica. Métodos: De 2000 a 2002, 80 pacientes (53 mulheres e 27 homens), com idade entre 12 e 56 anos, foram submetidos à simpatectomia toracoscópica para o tratamento de hiperidrose e acompanhados em média por 42,51 ± 5,98 meses. A satisfação destes pacientes quanto aos resultados do procedimento foi aferida por meio de uma escala de avaliação. O procedimento foi executado bilateralmente: no nível de T2 para a hiperidrose facial; de T3 e T4 para a hiperidrose axilar; e de T3 para a hiperidrose palmar. Resultados: No período pós-operatório, 68 pacientes (85,0%) apresentaram hiperidrose compensatória, que foi classificada como leve em 23 (33,85%), moderada em 23 (33,8%) e grave em 22 (32,4%). Quanto aos resultados da cirurgia, na avaliação dos pacientes, 70 deles (87,5%) se consideraram satisfeitos, enquanto 10 pacientes (12,5%) disseram estar insatisfeitos. O grau de satisfação do paciente variou de acordo com o sexo, a idade, o índice de massa corpórea (IMC) e a extensão da operação. A hiperidrose compensatória foi mais intensa no abdome e dorso do que nas pernas. Conclusões: Embora a hiperidrose compensatória seja um efeito adverso frequente após a simpatectomia, o grau de satisfação dos pacientes foi elevado. Os melhores candidatos para simpatectomia toracoscópica são mulheres adultas jovens com IMC ≤ 24,9 kg/m 2 .

Objective: The objective of this study was to describe the results of anatomic pulmonary resections performed by video-assisted thoracoscopy in Brazil. Methods: Thoracic surgeons (members of the Brazilian Society of Thoracic Surgery) were invited, via e-mail, to participate in the study. Eighteen surgeons participated in the project by providing us with retrospective databases containing information related to anatomic pulmonary resections performed by video-assisted thoracoscopy. Demographic, surgical, and postoperative data were collected with a standardized instrument, after which they were compiled and analyzed. Results: The surgeons provided data related to a collective total of 786 patients (mean number of resections per surgeon, 43.6). However, 137 patients were excluded because some data were missing. Therefore, the study sample comprised 649 patients. The mean age of the patients was 61.7 years. Of the 649 patients, 295 (45.5%) were male. The majority-521 (89.8%)-had undergone surgery for neoplasia, which was most often classified as stage IA. The median duration of pleural drainage was 3 days, and the median hospital stay was 4 days. Of the 649 procedures evaluated, 598 (91.2%) were lobectomies. Conversion to thoracotomy was necessary in 30 cases (4.6%). Postoperative complications occurred in 124 patients (19.1%), the most common complications being pneumonia, prolonged air leaks, and atelectasis. The 30-day mortality rate was 2.0%, advanced age and diabetes being found to be predictors of mortality. Conclusions: Our analysis of this representative sample of patients undergoing pulmonary resection by video-assisted thoracoscopy in Brazil showed that the procedure is practicable and safe, as well as being comparable to those performed in other countries.

Some lung diseases are true diagnostic challenges due to their various clinical presentations. Actinomycosis is one such disease, potentially affecting various organs and systems. We report the case of a patient with pulmonary actinomycosis as a pseudotumor, which is usually only diagnosed by thoracotomy or thoracoscopy.
