- Expression of Acetylcholine and Its Receptor in Human Sympathetic Ganglia in Primary Hyperhidrosis(2013) MOURA JUNIOR, Nabor B. de; DAS-NEVES-PEREIRA, Joao C.; OLIVEIRA, Flavio R. G. de; JATENE, Fabio B.; PARRA, Edwin R.; CAPELOZZI, Vera L.; WOLOSKER, Nelson; CAMPOS, Jose R. M. deBackground. The pathophysiologic characteristics of primary hyperhidrosis are not well understood and seem to be related to a sympathetic nervous system dysfunction. The resection of thoracic sympathetic chain ganglia is the most effective treatment for hyperhidrosis; however sympathetic ganglia function in normal individuals and in patients with hyperhidrosis is unknown. Methods. A cross-sectional study, in which 2 groups of 20 subjects were analyzed: the hyperhidrosis group (HYP), comprised of patients with hyperhidrosis who were eligible for thoracic sympathectomy, and the control group (CON) comprised of brain-dead organ donors without a history of hyperhidrosis. For each subject, the following were performed: resection of the third left sympathetic ganglion, measurement of the ganglion's diameter, and immunohistochemical evaluation by quantification of strong and weak expression areas of primary antibodies against acetylcholine and alpha-7 neuronal nicotinic receptor subunit. Results. The presence of a strong alpha-7 subunit expression area was 4.85% in patients with primary hyperhidrosis and 2.34% in controls (p < 0.001), whereas the presence of a weak expression area was 11.48% in the HYP group and 4.59% in the CON group (p < 0.001). Strong acetylcholine expression was found in 4.95% of the total area in the HYP group and in 1.19% in the CON group (p < 0.001), whereas weak expression was found in 18.55% and 6.77% of the HYP and CON groups, respectively (p < 0.001). Furthermore, diameter of the ganglia was 0.71 cm in the HYP group and 0.53 cm in the CON group (p < 0.001). Conclusions. There is a higher expression of acetylcholine and alpha-7 neuronal nicotinic receptor subunit in the sympathetic ganglia of patients with hyperhidrosis. Furthermore, the diameter of the thoracic sympathetic chain ganglia is larger in such patients. (Ann Thorac Surg 2013;95:465-71) (c) 2013 by The Society of Thoracic Surgeons
bookPart Derrames Pleurais(2013) WEREBE, Eduardo; CAMPOS, José Ribas Milanez de- Technical Difficulties and Complications of Sympathectomy in the Treatment of Hyperhidrosis: An Analysis of 1731 Cases(2013) ANDRADE FILHO, Laert Oliveira de; KUZNIEC, Sergio; WOLOSKER, Nelson; YAZBEK, Guilherme; KAUFFMAN, Paulo; CAMPOS, Jose Ribas Milanez deBackground: The aim of this study was to ascertain the technical difficulties and complications of video-assisted thoracic sympathectomy (VTAS) in the treatment of hyperhidrosis in a large group of patients. Methods: Between October 1995 and February 2008, 1731 patients with palmar, axillary, or craniofacial hyperhidrosis, who were treated using bilateral VTAS, were studied. We assessed the technical difficulties, early and late complications, and the approaches that were used to resolve them. Results: Therapeutic success was achieved in 91% of the cases as evidenced by anhidrosis. The most common and severe technical difficulty during the procedure was pleural adhesions in 116 cases (6.7%); azygos lobes were seen in 7 patients (0.4%) and apical blebs in 3 patients (0.2%). The most frequent postoperative immediate complication was postoperative pain in 1685 (97.4%) patients; pneumothorax with chest drainage was seen in 60 cases (3.5%), neurologic disorders involving the upper limbs in 36 cases (2.1%), Homer's syndrome in 11 cases (0.9%), significant bleeding in 8 cases (0.4%), and 1 patient had extensive subcutaneous emphysema. The most frequent late complication was compensatory hyperhidrosis, which occurred in 1531 cases (88.4%). Although 27.2% of the patients reported severe compensatory hyperhidrosis, only 2.5% expressed regret for undergoing surgery. Gustatory sweating occurred in 334 patients (19.3%). No deaths occurred in this series. Conclusions: VTAS is safe and has shown good results. The major complication is compensatory hyperhidrosis and, when severe, the patient may express regret for undergoing surgery. Improvements in instrumentation, adequate training, and careful patient selection may help to reduce the number of drawbacks associated with VTAS.
- Optimization of sympathectomy to treat palmar hyperhidrosis(2013) BISCHOF, G.; CAMERON, A. E. P.; CONNERY, C.; CAMPOS, J. R. M. De; HASHMONAI, M.; LICHT, P. B.; SCHICK, C. H.
- Objective evaluation of plantar hyperhidrosis after sympathectomy(2013) WOLOSKER, Nelson; ISHY, Augusto; YAZBEK, Guilherme; CAMPOS, Jose Ribas Milanez de; KAUFFMAN, Paulo; PUECH-LEAO, Pedro; JATENE, Fabio BiscegliOBJECTIVE: The aim of the present study was to prospectively, randomly, blindly, and objectively investigate how surgery affects plantar sudoresis in patients with palmar and plantar hyperhidrosis over a one-year period using a sudorometer (VapoMeter). METHODS: From February 2007 to May 2009, 40 consecutive patients with combined palmar hyperhidrosis and plantar hyperhidrosis underwent video-assisted thoracic sympathectomy at the T3 or T4 ganglion level (15 women and 25 men, with a mean age of 25 years). RESULTS: Immediately after the operation and during the one-year follow-up, all of the patients were free from palmar hyperhidrosis episodes. Compensatory hyperhidrosis of varying degrees was observed in 35 (87.5%) patients after one year. Only two (2.5%) patients suffered from severe compensatory hyperhidrosis. There was a large initial improvement in plantar hyperhidrosis in 46.25% of the cases, followed by a progressive regression of that improvement, such that only 30% continued to show this improvement after one year. The proportion of patients whose condition worsened increased progressively (from 21.25% to 47.50%), and the proportion of stable patients decreased (32.5% to 22.50%). This was not related to resection level; however, a lower intensity of plantar hyperhidrosis prior to sympathectomy correlated with worse evolution. CONCLUSION: Patients with palmar hyperhidrosis and plantar hyperhidrosis who underwent video-assisted thoracic sympathectomy to treat their palmar hyperhidrosis exhibited good initial improvement in plantar hyperhidrosis, which then decreased to lesser degrees of improvement over a one-year period following the surgery. For this reason, video-assisted thoracic sympathectomy should not be performed when only plantar hyperhidrosis is present.
- Variation of the Anthropometric Index for pectus excavatum relative to age, race, and sex(2013) REBEIS, Eduardo Baldassari; CAMPOS, Jose Ribas Milanez de; MOREIRA, Luis Felipe Pinho; PASTORINO, Antonio Carlos; PEGO-FERNANDES, Paulo Manuel; JATENE, Fabio BiscegliOBJECTIVES: To determine possible variations in the Anthropometric Index for pectus excavatum relative to age, race, and sex in individuals free of thoracic wall deformities. METHODS: Between 2002 and 2012, 166 individuals with morphologically normal thoracic walls consented to have their chests and the perimeter of the lower third of the thorax measured according to the Anthropometric Index for pectus excavatum. The participant characteristics are presented (114 men and 52 women; 118 Caucasians and 48 people of African descent). RESULTS: Measurements of the Anthropometric Index for pectus excavatum were statistically significantly different between men and women (11-40 years old); however, no significant difference was found between Caucasians and people of African descent. For men, the index measurements were not significantly different across all of the age groups. For women, the index measurements were significantly lower for individuals aged 3 to 10 years old than for individuals aged 11 to 20 years old and 21 to 40 years old; however, no such difference was observed between women aged 11 to 20 years old and those aged 21 to 40 years old. CONCLUSION: In the sample, significant differences were observed between women aged 11 to 40 years old and the other age groups; however, there was no difference between Caucasian and people of African descent.
- Use of oxybutynin for treating plantar hyperhidrosis(2013) WOLOSKER, Nelson; CAMPOS, Jose Ribas Milanez de; KAUFFMAN, Paulo; YAZBEK, Guilherme; NEVES, Samantha; PUECH-LEAO, PedroBackground To evaluate the effectiveness and patient satisfaction with the use of oxybutynin at low doses for treating plantar hyperhidrosis. Methods From January 2007 to December 2010, 35 consecutive patients with plantar hyperhidrosis were treated with oxybutynin. Data were collected from 30 patients (five patients were lost to follow-up). During the first week, patients received 2.5mg of oxybutynin once a day, 2.5 mg twice a day from the eighth to the 42nd day, and from the 43rd day to the end of the 12th week, 5mg twice a day. All of the patients underwent two evaluations: before and after the oxybutynin treatment, using a clinical questionnaire, and a clinical protocol for quality of life. Results More than 70% of patients experienced an improvement in plantar hyperhidrosis. Most of the patients showed improvements in quality of life (66.6%). The side effects were minor, the most frequent being dry mouth (76.7%). Conclusion Treatment of plantar hyperhidrosis with oxybutynin presents good results and improves quality of life. We believe that this therapeutic alternative is an excellent choice for the initial treatment of plantar hyperhidrosis.
- Effectiveness of oxybutynin for treatment of hyperhidrosis in overweight and obese patients(2013) WOLOSKER, Nelson; KRUTMAN, Mariana; KAUFFMAN, Paulo; PAULA, Rafael Pessanha de; CAMPOS, Jose Ribas M. de; PUECH-LEAO, PedroObjective: Until the present moment, the lack of efficient therapeutic options available for hyperhidrosis treatment in obese patients has left this population without prospect of clinical or quality of life (QOL) improvements. Outcomes of oxybutynin treatment for overweight and obese patients with hyperhidrosis are unknown. This study aims to investigate the results related to clinical and QOL improvements in this specific population, submitted to a 12-week protocol treatment with oxybutynin. Methods: 559 patients with palmar and axillary hyperhidrosis, routinely followed in this service, were divided into the groups, according to their body mass index (BMI) (<25 kg/m(2); 25 < BMI < 30 kg/m(2), > 30 kg/m(2)). Improvements in QOL and in the level of hyperhidrosis were analyzed after 12 weeks of protocol treatment with oxybutynin. These parameters were investigated using a scoring system based on a scientifically validated clinical questionnaire, applied before and after treatment. Results: 67.8% of the overweight sample group and 63% of the obese patients presented ""partial"" or ""great"" improvement in the level of hyperhidrosis. Over 65% of patients demonstrated improvement in QOL (""much better"" or ""slightly better"") for all three groups, with no statistical difference between them. The only adverse event associated with oxybutynin was dry mouth, observed in 63.0% of the patients. Conclusion: Overweight and obese patients with palmar or axillary hyperhidrosis present significant improvement in QOL after treatment with oxybutynin, and the results are comparable to those of normal weight individuals.
- Transdiaphragmatic intercostal hernia: imaging aspects in three cases(2013) MACEDO, Ana Carolina Sandoval; KAY, Fernando Uliana; TERRA, Ricardo Mingarini; CAMPOS, Jose Ribas Milanez de; ARANHA, Andre Galante Alencar; FUNARI, Marcelo Buarque de GusmaoTransdiaphragmatic intercostal hernia is uncommon and mostly related to blunt or penetrating trauma. We report three similar cases of cough-induced transdiaphragmatic intercostal hernia, highlighting the anatomic findings obtained with different imaging modalities (radiography, ultrasonography, CT, and magnetic resonance) in each of the cases.
