PURPOSE To evaluate the frequency of symptoms of depression, suicidal ideation, suicide behavior, and hopelessness among adolescents in southern Brazil. METHODS The Self-Report Questionnaire (SRQ) was administered to a random sample of 126 community youngsters to screen for mental problems, the Montgomery-Asberg Depression Rating scale for signs and symptoms of depression, an adapted version of DIS (Diagnostic Interview Schedule) for suicidal ideation and behavior, and the Backs Hopelessness scale (adapted version). Social class, cognitive performance, age, and sex were also analyzed. RESULTS Levels of symptoms of depression, suicidal ideation and behavior, and hopelessness were higher among those who were SRQ positive (8%). Female youngsters presented higher SRQ scores and on the Montgomery-Asberg scale. Cognitive performance was similar among all groups. Differences were not found according to social classes. The 15-17 year-old individuals (middle stage) presented higher hopelessness than the other stages of adolescence. CONCLUSIONS The present findings suggest that screening for mental health conditions by self-report questionnaires may be of value of identify groups at major risk for violent, self-destructive behavior among community adolescents.

OBJECTIVE: To evaluate the impact of an aggressive treatment approach using muscle flaps or omentopexy in infections of the sternum and anterior mediastinum following sternotomy on mortality, as compared to that of a conservative treatment approach. METHODS: Data were collected prior to, during and after the surgical procedures. Group A (n = 44) included patients submitted to conservative treatment-debridement together with resuture or continuous irrigation with polyvinylpyrrolidone-iodine solutions, or even with second-intention wound healing (retrospective data). Group B (n = 9) included patients in whom infection was not resolved with conservative treatment, and who therefore underwent aggressive treatment (intermediate phase). Group C (n = 28) included patients primarily submitted to aggressive treatment (prospective data). RESULTS: Postoperative hospital stays were shorter in the patients submitted to aggressive treatment (p < 0.046). There were 7 deaths in group A, 1 in group B, and 2 in group C. However, the classical level of significance of α = 0.05 was not reached. CONCLUSION: Aggressive treatment also proved to be effective when the infection was not resolved with conservative treatment. These findings demonstrate that the proposed treatment provides excellent results.

O tratamento cirurgico do paciente com estenose traqueobronquica exige uma avaliacaoindividualizada em razao da complexidade de sua origem, sendo a traqueoplastia considerada amodalidade ideal. As causas mais comuns de estenose sao devidas a intubacao traqueal e aodesenvolvimento de neoplasias e estas condicoes sao justamente as que mais se beneficiam com otratamento endoscopico quando a correcao cirurgica nao esta indicada. Na atualidade, os meiosendoscopicos incluem a aplicacao de diversos tipos de

OBJECTIVE We report preliminary results obtained with urgent lung transplantation (ULTx) in cystic fibrosis (CF) patients, based on a French high emergency lung allocation (HELA) system, and the impact of this system on waiting-list death. METHODS The medical records of the first 15 CF patients receiving ULTx between June 2007 and May 2010 at Hôpital Européen Georges Pompidou, France, were retrospectively reviewed. ULTx patients (URG group, n=15) were compared with our entire cohort of CF patients receiving elective lung transplants (LTx) (ELT group, n=118). RESULTS Both groups were similar in terms of use of cardiopulmonary bypass (CPB), length of stay in the intensive care unit (ICU), and intubation > 72 h. Incidence of primary graft dysfunction (PGD) and perioperative mortality was also similar in both groups, but graft ischemic time and severity of PGD were higher in the URG group. One-year and 2.5-year survival rates were, respectively, 73% and 54.5% for the URG group. Death on the waiting list and time to LTx (including all pulmonary diagnoses) decreased by 67% and 64%, respectively. CONCLUSIONS Although still preliminary and with a short follow-up period, our results suggest that the allocation of LTx to CF patients based on the HELA criteria yielded acceptable outcomes and improved waiting-list death rate and time to LTx.

ABSTRACT 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.

Pulmonary resection after lung transplantation in end-stage cystic fibrosis presents unique challenges, and scant literature exists to guide physicians. We retrospectively reviewed 78 transplants for cystic fibrosis performed between 2003 and 2008. Fourteen patients underwent posttransplantation pulmonary resection. We analyzed the indications, surgical procedures, outcomes, and survival. Three pneumonectomies, 4 lobectomies, and 11 wedge resections were carried out. We identified 2 groups based on indication: a diagnostic group, and a therapeutic group of patients in whom the indications were septic native lung in 2, allograft infection in 2, lobar torsion in 2, pulmonary infarction in 2, and size mismatch in 4. The mean intensive care unit and hospital stays were 29 and 50 days, respectively. Four (28.57%) patients died during follow-up, including 2 who underwent pneumonectomy; 10 (71.43%) are still alive. Survival was 43.43 ± 8.06 months, and it was not significantly different from that in cystic fibrosis patients who had lung transplantation without pulmonary resection. Pulmonary resection following lung transplantation in cystic fibrosis patients showed acceptable survival and surgical risk, but metachronous pneumonectomy was associated with higher mortality.

We describe a case series of 35 patients with either benign (14) or malignant (21) tracheal stenosis who were treated using a novel silicone stent, the HCPA-1, designed to prevent migration. Between March 2001 and September 2008, 13 women and 22 men received 41 HCPA-1 stents. The median duration of stenting in benign cases was 457 days (range, 4–2, 961 days). Successful stent removal with curative results was accomplished in 2 patients with tracheomalacia and 1 with post-intubation stenosis. In malignant cases, the median duration of stenting was 162 days (range, 1–1, 279 days). Five patients had tumor progression with obstruction requiring repeated laser resection, dilatation, or additional stents. Two patients died due to airway obstruction despite bronchoscopic intervention. Twelve patients with malignant lesions died with the stent in place. At the end of the study, 3 patients with malignant disease remained alive; 2 were lost to follow-up. The HCPA-1 stent proved to be safe, with no severe complications during the study period, and effective in improving quality of life with relief of dyspnea.

OBJECTIVE To evaluate the importance of stem cells derived from adipose tissue in reducing graft inflammation in a murine model of allogeneic heterotopic tracheal transplant. METHODS We performed a heterotopic tracheal allografting in dorsal subcutaneous pouch and systemically injected 5x105 mesenchymal stem cells derived from adipose tissue. The animals were divided into two groups according to the time of sacrifice: T7 and T21. We also carried out histological analysis and digital morphometry. RESULTS The T7 animals treated with cell therapy had median obstructed graft area of 0 versus 0.54 of controls (p = 0.635). The treated T21 subjects had median obstructed graft area of 0.25 versus 0 in controls (p = 0.041). CONCLUSION The systemically injected cell therapy in experimental murine model of bronchiolitis obliterans did not reduce the severity of the allograft inflammation in a statistically significant way in seven days; Conversely, in 21 days, it increased the allograft inflammatory process.
