Marcelo Fouad Rabahi, Luísa Oliveira de Paiva, Mariana Almeida de Castro, Orlando Roberto da Silva Neto
International Journal of Clinical Medicine (IJCM) , 2014, DOI: 10.4236/ijcm.2014.512096

Objective: To analyze bronchoscopy as a diagnostic and therapeutic method in patients with tracheobronchial foreign body. Methods: We analyzed reports of flexible bronchoscopy with diagnose of tracheobronchial foreign body performed from 2003 to 2013 in São Salvador Hospital, in Goiania, capital of Goiás. The analysis was based on: sex and age of the patients, airways and foreign body characteristics, foreign body localization, success rate and rate of bleeding. We calculated the frequencies after analyzing the data. Results: We analyzed 26 reports of the studied period and found that 57.7% of the patients were male with median age of 58.83 years old (+—13.79). The airways characteristics were normal in most of the cases. Sputum wasn’t found in 57.69% of the cases. Foreign bodies were located in right bronchus in 88.46% of the cases, and the extraction of them was successful in 80.76% of the cases. The absence of bleeding was reported in 96.15% of the cases. Conclusions: Flexible bronchoscopy is a notably successful method in management of tracheobronchial foreign bodies. Airways characteristics aren’t good indicatives of FB’s presence, once they are normal in most of the times.

American Journal of Analytical Chemistry (AJAC) , 2014, DOI: 10.4236/ajac.2014.513092
Abstract: This paper presents the Taguchi Method, a statistical design modelling for experiments applied in environmental engineering. This method was applied to optimize the treatment conditions of polyester-resin effluent by means of Advanced Oxidative Processes (AOPs) using chemical oxygen demand (COD) as response parameter. The influence of each independent parameter including respective interactions was evaluated by Taguchi Method, which allowed determining the most statistically significant variables and conditions to best fit the process. Results showed that Taguchi Method is a very useful tool for environmental engineering field and possible simplifications of analysis and calculations through commercially available software.

Carlos Alberto Batista Santos, Roberto Remígio Florêncio, Vinina da Silva Ferreira, Patrícia Luiza de Oliveira-Rebou?as
Creative Education (CE) , 2018, DOI: 10.4236/ce.2018.915182
Abstract: The use of by-products of wild animals for the production of handicrafts is a common practice among indigenous peoples. Natives prefer to hunt birds because of the beauty and diversity of their feathers. In the Brazilian Northeast, this practice involves several hunting techniques, according to the species type. This research aimed to list the species of birds used in the handicraft of the Truká indigenous people and to characterize the techniques used to capture birds employed by the native hunters in the four ethnic settlements in the backlands of Pernambuco and Bahia. The information was obtained through semi-structured interviews applied to 23 indigenous artisans, in the villages Truká of Cabrobó, Orocó, Sobradinho and Paulo Afonso. Four capture techniques, slingshots, firearms, and traps have been identified, such as the trap and the trapdoor. The traps are the most commonly used technologies in the study area. In addition to crafts, informants have indicated the use of bird species in food, traditional medicine and domestic breeding as pets.

Oliveira, Lucinei Roberto de;Ribeiro-Silva, Alfredo;Zucoloto, Sergio;
Jornal Brasileiro de Patologia e Medicina Laboratorial , 2006, DOI: 10.1590/S1676-24442006000500010
Abstract: background: the buccal cancer incidence in brazil is one of the highest in the world. objectives: to evaluate profile, risk factors and survival in patients with oral squamous cell carcinoma between 1982 and 2002 in a brazilian population. material and method: age, gender, tumor site, previous clinical history, tobacco and alcohol consumption, actinic exposure, trauma by dental prosthesis, recurrences, metastases and survival rates were obtained from the medical files. results: from 340 patients, 84.4% were men and 15.6%, women (5.4:1). the lingual lesions were the most frequent ones (27.9%). twenty percent of the patients reported trauma by dental prosthesis and in 73.8% of the lesions in lower lip an unprotected actinic exposure was reported. there was no difference between anatomical region and tobacco consumption concerning recurrences and regional or distant metastases. the average time of previous clinical history was 13 months, with significant differences among the anatomical regions. the 5-year-old survival rates were 24%. the survival rate of patients with recurrences and/or metastases varied according to age (< 60 or > 60), but not to previous medical history or anatomical regions. the man/woman discrepancy found was high, but decreased according to the rise of age. tobacco and alcohol consumption is elevated in this population, but did not influence recurrences and metastases. the time of evolution of the lesions was long until the search for medical service. conclusions: the low survival rates reflect the need of a more careful attention to buccal cancer in this population.

Silva, Roberto Carlos de Oliveira e;Cioffi, Ant?nio Carlos;
Revista do Colégio Brasileiro de Cirurgi?es , 1999, DOI: 10.1590/S0100-69911999000300016
Abstract: the diagnosis of pancreatic masses represents a great challenger for imaging studies. however the occurrence of pancreatic masses have been reported more frequently in the last years due to advances in imaging diagnostic methods. during the last decade, the surgical approach of pancreatic masses was limited to an attempt of establishing histological diagnosis, staging and evaluation of resection of these masses. recently, the approach and staging of pancreatic masses was facilitated by sophisticated methods of diagnosis, especially, ultrasound, dynamic computerized tomography, magnetic resonance imaging (/rm), angiography, endoscopic retrograde cholangiopancreatography (cpre), endoscopic ultrasound, laparoscopy and biochemical tumors markers. the present paper reports a case of a pancreatic mass due to foreign body in which the imaging study helped to determine out this rare etiological agent that has not been previouly described in literature.
