Abstract Introduction: Optimized allocation of medical resources to patients with COVID-19 has been a critical concern since the onset of the pandemic. Methods: In this retrospective cohort study, the authors used data from a Brazilian tertiary university hospital to explore predictors of Intensive Care Unit (ICU) admission and hospital mortality in patients admitted for COVID-19. Our primary aim was to create and validate prediction scores for use in hospitals and emergency departments to aid clinical decisions and resource allocation. Results: The study cohort included 3,022 participants, of whom 2,485 were admitted to the ICU; 1968 survived, and 1054 died in the hospital. From the complete cohort, 1,496 patients were randomly assigned to the derivation sample and 1,526 to the validation sample. The final scores included age, comorbidities, and baseline laboratory data. The areas under the receiver operating characteristic curves were very similar for the derivation and validation samples. Scores for ICU admission had a 75% accuracy in the validation sample, whereas scores for death had a 77% accuracy in the validation sample. The authors found that including baseline flu-like symptoms in the scores added no significant benefit to their accuracy. Furthermore, our scores were more accurate than the previously published NEWS-2 and 4C Mortality Scores. Discussion and conclusions: The authors developed and validated prognostic scores that use readily available clinical and laboratory information to predict ICU admission and mortality in COVID-19. These scores can become valuable tools to support clinical decisions and improve the allocation of limited health resources.

Abstract The objective of this work was to evaluate the possible modifications due to industrial processing in the volatiles (HS-SPME/GC-MS), bioactive compounds (content total, and phenolic profile by UFLC-DAD) and antioxidant capacity (ABTS, DPPH, FRAP, ORAC) of fresh and processed mango pulp with addition of additives, pasteurized, and pasteurized with additives. The physicochemical characteristics of the samples were evaluated. All parameters were significantly (p≤0.05) affected by processing. According to the PCA analysis, the stability of the samples was influenced by the thermal processing and the work clearly demonstrated the separation between the analyzed samples as a function of the effect of thermal processing. It is concluded that industrial processing, although important for the preservation of useful life and maintenance of the microbiological quality of mango pulp, influence the functional and aromatic properties, causing a significant reduction in the volatile and bioactive compounds, which can negatively influence the acceptance of the processed product by consumers.

Abstract Duplex and super duplex stainless steels have high corrosion resistance, excellent mechanical properties, and high impact strength. Such characteristics make these steels able to operate in various segments of the industry, especially in aggressive environments. These alloys have higher strength than austenitic and ferritic stainless steels and their operation is generally restricted to temperatures lower than 300 °C. Most steels and alloys only exhibit elasto-viscoplastic behavior at temperatures higher than 1/3 of the absolute melting temperature. The objective of this work was to make an experimental study showing that the duplex and superduplex steels present a rate-dependent behavior even at room temperature (around 25 °C). Two different alloys: duplex stainless steel UNS 31803F51 and super duplex UNS S32760GRF55 were used in the study. Simple models were proposed to describe how the rate-dependent portion of the stress (called at this paper “the viscous term”) depends on the strain rate. A simple procedure to identify experimentally all material constants that appear in the theory is presented. The experimental results are in very good agreement with the model predictions.

RESUMO Genótipos de citros mostram uma gama de resistência à infecção de Xanthomonas citri subsp. citri (Xcc), agente causal do cancro cítrico asiático (ACC). O objetivo deste estudo foi avaliar um método de inoculação em folha destacada para comparar nove genótipos diferentes de citros que apresentam graus de resistência à ACC e, avaliar a infecção, colonização e desenvolvimento de sintomas das variedades utilizando Microscopia Eletrônica de Varredura (MEV). A inoculação de Xcc em folhas foi realizada através de ferimentos produzidos com agulhas. Aos 7, 10 e 13 dias após a inoculação (DAI), diâmetros de lesão foram mensurados. A variedade Pêra IAC foi a mais resistente ao patógeno e apresentou lesões com menor diâmetro e a variedade Washington foi a mais suscetível e apresentou as maiores lesões, indicando baixa resistência à Xcc. As imagens de MEV foram feitas no desenvolvimento da lesão, e secções foram cortadas a partir das lesões da doença nas variedades testadas. A variedade mais resistente, Pêra IAC, teve aberturas estomáticas menores e produziram uma maior quantidade de exsudados foliares em comparação com a variedade Washington. Nossa hipótese é que os exsudados podem conter compostos tóxicos de Xcc e, portanto, pode ser um mecanismo de defesa para a infecção por Xcc, embora novas pesquisas são necessárias para estabelecer quaisquer efeitos antibióticos de exsudato contra o cancro cítrico.

ABSTRACT Citrus genotypes show a broad range of resistance to infection with Xanthomonas citri subsp citri (Xcc), the causal agent of Asiatic citrus canker (ACC). The aim of this study was to evaluate a detached leaf inoculation method to compare nine different citrus genotypes that exhibit varied resistance levels to ACC, and to evaluate infection, colonization and symptom development of the varieties by using Scanning Electron Microscopy (SEM). Inoculation of Xcc in the leaves was carried out by producing injuries with needles. Lesion diameters were measured at 7, 10 and 13 days after inoculation (DAI). The variety Pera IAC was most resistant to the pathogen and had lesions with smaller diameters, while the variety Washington was most susceptible and had the largest lesions, indicating low resistance to Xcc. SEM images were taken from the lesion development, and sections were obtained from the disease lesions in the tested varieties. The most resistant variety, Pera IAC, had smaller stomatal openings and produced greater quantity of foliar exudates, compared with the variety Washington. We hypothesize that the exudates may contain Xcc toxic compounds and thus may be a defense mechanism against infection by Xcc, but further research is required to establish any antibiotic effects of the exudates against citrus canker.

CONTEXTO: Macroadenomas hipofisários são tumores intracraniais raros. Em alguns casos, podem apresentar comportamento agressivo e invadir o seio esfenoidal e a cavidade nasal, causando sintomas não usuais. Neste relato de caso, descrevemos um caso atípico de adenoma hipofisário manifestando-se como uma massa nasal.RELATO DE CASO: A paciente de 44 anos, do sexo feminino, apresentava amenorreia e galactorreia por 10 meses associando-se a obstrução nasal, macroglossia e acromegalia. Os níveis do hormônio de crescimento e de prolactina apresentaram-se aumentados. Ressonância magnética mostrou uma grande massa originada da superfície inferior da glândula hipofisária associada com erosão da sela túrcica e extensão do tumor através do seio esfenoidal e cavidade nasal. Análise histopatológica demonstrou adenoma hipofisário cromófobo com células epiteliais arrendondadas densamente agrupadas com algumas atipias e escassas figuras de mitose. Não houve evidências de metástase.CONCLUSÃO: O macroadenoma invasivo para a cavidade nasal é uma condição rara e há poucos relatos similares descritos na literatura. Este trabalho contribui para mostrar que, na presença de sintomas atípicos como a obstrução nasal, a extensão para o seio esfenoidal e para a nasofaringe deve ser considerada e investigada para um diagnóstico precoce.

CONTEXT: Pituitary macroadenomas are rare intracranial tumors. In a few cases, they may present aggressive behavior and invade the sphenoid sinus and nasal cavity, causing unusual symptoms. In this paper, we report an atypical case of pituitary adenoma presenting as a nasal mass.CASE REPORT: The patient was a 44-year-old woman who had had amenorrhea and galactorrhea for ten months, with associated nasal obstruction, macroglossia and acromegaly. Both growth hormone and prolactin levels were increased. Magnetic resonance imaging showed a large mass originating from the lower surface of the pituitary gland, associated with sella turcica erosion and tumor extension through the sphenoid sinus and nasal cavity. Histopathological analysis demonstrated a chromophobe pituitary adenoma with densely packed rounded epithelial cells, with some atypias and rare mitotic figures. There was no evidence of metastases.CONCLUSION: Macroadenoma invading the nasal cavity is a rare condition and few similar cases have been reported in the literature. This study contributes towards showing that tumor extension to the sphenoid sinus and nasopharynx needs to be considered and investigated in order to make an early diagnosis when atypical symptoms like nasal obstruction are present.

O objetivo do trabalho foi proceder a uma revisão criteriosa de uma casuística de 90 pacientes submetidos às ressecções colorretais por via videolaparoscópica no decurso de 12 meses (maio de 2009 a maio de 2010). A média etária foi de 62,1 anos, com extremos de 20 e 93 anos, sendo a maioria dos pacientes do sexo feminino (52; 57,8%). O diagnóstico mais comum foi câncer colorretal, com 60 casos (66,7%), seguido pelos pólipos colorretais, com 12 casos (13,4%), doença diverticular, com sete casos (7,8%), e outros diagnósticos, com 11 casos (12,1%). O preparo intestinal mais realizado foi com o Picolax (53 casos; 58,9%); 76 pacientes foram submetidos à colonoscopia e biópsia (84,4%). As cirurgias mais realizadas foram as retossigmoidectomias (54 casos; 60,0%), seguidas pelas hemicolectomias direitas (20 casos; 22,2%). O tempo de execução da maioria das cirurgias foi entre duas e três horas (34 casos; 37,8%) e entre três e quatro horas (24 casos, 26,7%), com média de 203 minutos. Em 81 casos, houve anastomoses (90,0%), a maioria mecânica intra-abdominal (55,6%) e manual extra-abdominal (25 casos; 27,8%), tendo sido o conjunto de grampeadores circulares e lineares articulados os recursos mais utilizados (50 casos; 55,6%). O eletrocautério foi usado em 68 pacientes (75,6%). A incisão abdominal mais usada foi a de Mallard (39 casos, 43,4%) e a mediana (22 casos; 24,4%), sendo as extensões mais comuns entre 6 e 10 cm (55 casos; 78,6%). Houve 12 intercorrências peroperatórias (13,2%), que levaram a conversões para laparotomia. A média de dimensões das peças cirúrgicas foi 33,2 cm, a maioria entre 21 e 30 cm (51 casos, 56,8%). Houve 13 complicações pós-operatórias (14,4%), 11 delas cirúrgicas (12,2%) e duas clínicas (2,2%), das quais decorreram três óbitos, sendo dois cirúrgicos e um clínico. O tempo médio de internamento foi de 5,3 dias, tendo sido 57 (63,3%) a até cinco dias. Foram para o CTI 28 pacientes (31,1%), sobretudo por conta de comorbidades (22 casos; 24,4%). A liberação de dieta oral foi de um dia para 49 pacientes (54,5%). Os autores comparam os resultados com a bibliografia correlata.

The objective was to undertake a careful review of a sample of 90 patients who underwent laparoscopic colorectal resections through the course of 12 months (May 2009 to May 2010). The average age was 62.1 years, with extremes of 20 and 93 years, mostly female (52 patients; 57.8%). Bowel preparation was performed with Picolax in 53 patients (58.9%); 76 patients underwent colonoscopy and biopsy (84.4%). Colorectal cancer was the most common disease (60 cases; 66.7%), followed by polyps (12 cases; 13.4%), diverticular disease (7 cases; 7.8%) and other diseases (11 cases; 12,1%). The surgeries performed were retosigmoidectomy (54 cases; 60.0%), followed by right hemicolectomy (20 cases; 22.2%) and others. Most of the surgeries were carried out between 2 and 3 hours (34 cases; 37.8%) and between 3 and 4 hours (24 cases; 26.7%), with an average of 203 minutes. In 81 cases, there were anastomosis (90.0%), most mechanical intra-abdominal (55.6%) and manual extra-abdominal (25 cases, 27.8%), being the set of circular and linear articulated staplers the most commonly used features (50 cases, 55.6%). Electrocautery was used in 68 patients (75.6%). The most used abdominal incision was Mallard incision (39 cases; 43.4%) and median incision (22 cases; 24.4%), being the most common extensions between 6.0 and 10.0 cm (55 cases; 78.6%). There were 12 postoperative complications (13.2%), leading to conversions to laparotomy. The average size of surgical specimens was 33.2 cm, mostly between 21 and 30 cm (51 cases; 56.8%). There were 13 postoperative complications (14.4%), being 11 surgical (12.2%) and two clinics (2.2%) of which took place three deaths, being two from surgery and one from comorbidities. The mean length of hospital stay was 5.3 days, and 57 patients (63.3%) up to 5 days. 28 patients were admitted in the ICU (31.1%), mainly because of comorbidities (22 cases; 24.4%). The release of oral intake was a day for 49 patients (54.5%). The authors compare the results with related literature and confirm the similarities.

O objetivo do trabalho foi proceder a uma revisão criteriosa de uma casuística de 120 pacientes portadores de câncer colorretal operados por via videolaparoscópica (grupo-Video, 60 pacientes) e por via laparotômica (grupo-Lap, com 60 pacientes), no decurso de 12 meses (maio de 2009 a maio de 2010). A média etária foi de 58 anos, sendo 58,8 anos no grupo-Lap e 57,3 no grupo-Video, e a maioria era do sexo feminino em ambos os grupos (grupo-Lap - 55,0% e grupo-Video - 61,7%, com média de 58,3 anos). Todos os pacientes de ambos os grupos foram submetidos à colonoscopia e biópsia, com diagnóstico histopatológico de adenocarcinoma. Na distribuição dos tumores pelo intestino grosso no grupo-Lap, 43 se localizavam no reto e sigmoide (71,7%) contra 45 no grupo-Video (75,0%), mas com diferenças entre reto baixo (grupo-Lap, 13,3%; grupo-Video, 16,7%) e alto (grupo-Lap, 30,0%; grupo-Video, 16,7%), sigmoide e retossigmoide (grupo-Lap, 28,4%; grupo-Video, 41,6%). As cirurgias mais realizadas foram as retossigmoideCtomias abdominais altas (grupo-Lap, 27 casos, 45,0%; grupo-Video, 33 casos, 55,0%), seguidas pelas hemicolectomias direitas com anastomose íleo-transverso (grupo-Lap, 16 casos, 26,6%; e grupo-Video, 13 casos, 21,7%). As extensões das peças cirúrgicas foram maiores no grupo-Lap (média de 46,1 cm contra 30,0 cm no grupo-Video) em decorrência de maior número de cirurgias que resultaram peças de grandes dimensões. Quando se comparam as mesmas técnicas cirúrgicas, a diferença não persiste, como nos casos das retossigmoidectomias (grupo-Lap com 32 casos, média de 28,2 cm; grupo-Video com 39 casos, com média de 26,6 cm). No tocante à gradação TNM dos tumores, a gradação T3N0M0 foi a mais comum: grupo-Lap com 30 casos (50,0%) e grupo-Video com 35 casos (58,4%). No tocante à contagem de linfonodos nas peças cirúrgicas, nenhuma diferença foi notada: total de 810 linfonodos no grupo-Lap, com média de 13,5 linfonodos por peça, e total de 862 linfonodos no grupo-Video, com média de 14,3 linfonodos por peça. Não houve diferença também no tocante à contagem de linfonodos nas peças cirúrgicas, mais comuns entre 11 e 15: 34 casos no grupo-Lap (56,7%) e 38 no grupo-Video (63,3%). Assim, nenhuma diferença foi notada entre os dois grupos (grupo-Lap e grupo-Video) no tocante aos critérios oncológicos cirúrgicos.

The objective was to undertake a careful review of a consecutive series of 120 patients with colorectal cancer approached by laparoscopic surgery (Video-group, 60 patients) and by laparotomy (Lap-group, 60 patients), during 12 months (May 2009 to May 2010). The average age was 58 years and 58.8 years in group-Lap and 57.3 years in Video-group, the majority being females in both groups (Lap-group - 55.0% and Video-group - 61.7%, general mean 58.3 years). All patients in both groups underwent colonoscopy and biopsy with histopathologic diagnosis of adenocarcinoma. As far as distribution of tumors in the large intestine in Lap-group, 43 tumors were located in the rectum, rectosigmoid and sigmoid colon (71.7%) versus 45 in Video-group (75.0%), but with differences between low rectum (Lap-group 13,3%, Video-group 16.7%) and upper rectum (Lap-group 30.0%, Video-group 16.7%), sigmoid and rectosigmoid (Lap-group 28.4%, Video-group 41.6%). The most performed surgery was abdominal rectosigmoidectomy (Lap-group 27 cases, 45.0%; and Video-group 33 cases, 55,0%), followed by right hemicolectomy (Lap-group 16 cases, 26,6%; and Video-group 13 cases, 21.7%). The extensions of the surgical specimens were greater in Lap-group (mean 46.1 cm vs. 30.0 cm in Video-group), but due to higher number of surgeries that resulted in longer specimens. When comparing same surgical techniques, the difference does not persist as in cases of retosigmoidectomy (Lap-group with 32 cases, mean 28.2 cm; and Video-group with 39 cases, mean 26.6 cm). With regard to TNM staging T3N0M0, tumors was the most common in Lap-group with 30 cases (50.0%) and Video-group with 35 cases (58.4%). Regarding the lymph nodes count in surgical specimens, no difference was noted: total of 810 lymph nodes in specimens of Lap-group with a mean of 13.5 nodes per specimen, and total of 862 lymph nodes in Video-group with an average of 14.3 nodes per specimen. No difference was noted in relation to the count of lymph nodes in surgical specimens: the number of nodes was most commonly between 11 and 15 per specimen: 34 cases in Lap-group (56.7%) and 38 in Video-group (63.3%). Thus, no difference was noted between the two groups (Lap-group and Video-group) as far as oncologic and surgical criteria are concerned.

A análise retrospectiva de 74 prontuários de pacientes do Sistema Único de Saúde (SUS), operados de câncer colorretal pelo Residente R2 supervisionado e auxiliado por preceptores, permitiu as seguintes conclusões: a média etária dos pacientes foi 57,2, sendo as sexta e sétima décadas responsáveis por 51,4% dos pacientes. O câncer retal foi preponderante nas mulheres (54,1%). As localizações mais comuns dos tumores foram no sigmoide (31,1%), reto alto (24,3%) e ceco (17,6%). As cirurgias mais realizadas foram a retossigmoidectomia com anastomose colorretal (36,6%), e hemicolectomia direita com anastomose íleo-transverso (21,7%). As características anatômicas dos tumores, baseadas na classificação TNM, mais comuns foram: T3 (62,1%), N0 (59,5%) e M0 (77,0%) (p<0,05). O número médio de gânglios encontrados nas peças cirúrgicas foi de 10,4. Foram feitas 63 anastomoses (85,1%), das quais 38 (60,3%) foram mecânicas e 25, manuais (39,7%). Houve 14 comorbidades (18,9%), destacando-se a caquexia (oito casos). O índice de complicações cirúrgicas foi de 12,2% (nove casos), sendo as cirurgias que mais causaram complicações as colectomias totais com anastomose íleo-retal (40,0%) e as retossigmoidectomias abdominais, com duplo grampeamento (20%), sendo as complicações mais comuns as fístulas anastomóticas (cinco casos). As complicações (nove) decorreram mais das comorbidades (sete) que do ato cirúrgico (duas). As cirurgias que demandaram menos tempo foram: as laparotomias com ileostomia (média de 75 minutos) e as com colostomia (média de 95 minutos), sendo os maiores tempos ocupados pela proctocolectomia total com ileostomia definitiva (240 minutos) e as hemicolectomias esquerdas com anastomose transverso-retal (240 minutos), sendo o tempo médio equivalente a 160 minutos. As menores peças cirúrgicas foram as decorrentes da cirurgia de Hartmann (29 cm) e de retossigmoidectomia abdominal (32 cm); e as mais extensas, as peças de colectomia total com anastomose íleo-retal (120 cm) e proctocolectomia total com ileostomia definitiva (150 cm), ficando a média em 34,5. Houve 12 óbitos (16,2%), dois dos quais diretamente relacionados à cirurgia (um caso de deiscência de anastomose e um de evisceração); três relacionados à complicações de ordem clínica (dois casos de TEP e um de broncopneumonia); e sete comorbidades

In the framework of postgraduate Coloproctology for 2009, two graduate students conducted the second year as principal surgeons, 129 major surgeries, always assisted effectively by one or two tutors. All surgeries were performed on public patients in Santa Casa de Belo Horizonte, with absolute presence of members of the Grupo de Coloproctologia da Santa Casa de Belo Horizonte e Faculdade de Ciências Médicas de Minas Gerais (GCP-CBHS-FCMMG). A retrospective analysis of 74 medical records of patients from the Brazilian National Health System, resected of colorectal cancer by Resident R2, supervised and assisted by mentors, could get into the following conclusions: the average age of patients was 57.2, and the sixth and seventh decades accounted for 51.4% of the patients. The rectal cancer was predominant in women (54.1%). The most common sites of tumors were in the sigmoid (31.1%), rectum (24.3%), and cecum (17.6%). The most commonly performed procedures were retossigmoidectomy with colorectal anastomosis (36.6%) and right hemicolectomy with ileo-transverse anastomosis (21.7%). The anatomical characteristics of the tumors based on TNM classification findings were: T3 (62.1%), N0 (59.5%), and M0 (77.0%) (p<0.05). The average number of lymph nodes found in surgical specimens was 10.4. Sixty-three anastomoses (85.1%) were carried out, being 38 (60.3%) mechanical and 25, manual (39.7%). There were 14 comorbidities (18.9%), the cachexia having more prominence (eight cases). The rate of surgical complications was 12.2% (nine cases), and the surgeries that have caused more complications were total colectomy with ileo-rectal anastomosis (40.0%), and double stapled abdominal retossigmoidectomy (20%). The most common complications were anastomotic fistula (five cases). Complications (nine) were more caused by comorbidities (seven) than by the surgical procedure (two). The surgeries that required less time were: laparotomy with ileostomy (average of 75 minutes) and with colostomy (average of 95 minutes), and the longest times were occupied by total proctocolectomy with definite ileostomy (240 minutes) and left hemicolectomy with transverse-rectal anastomosis (240 minutes), with an average length of 160 minutes. The smaller specimens were those resulting from Hartmann's procedure (29 cm) and retossigmoidectomy (32 cm); and the most extensive specimens were of total colectomy with ileorectal anastomosis (120 cm) and total proctocolectomy with terminal ileostomy (150 cm), with the mean at 34.5. There were 12 deaths (16.2%), two of which directly related to surgery and the other related to clinical complications and comorbities

Dentro do Programa de pós-graduação em Coloproctologia, durante o ano 2009, os dois pós-graduandos de segundo ano realizaram, como cirurgiões principais, 129 cirurgias de grande porte, sempre assistidos, efetivamente, por um ou dois preceptores. Todas as cirurgias foram realizadas em pacientes do SUS, na Santa Casa de Belo Horizonte, com absoluta presença dos membros do Grupo de Coloproctologia da Santa Casa e Faculdade de Ciências Médicas de Minas Gerais (GCP-SCBH-FCMMG). Foi feita uma análise retrospectiva dos 129 prontuários, permitindo várias observações importantes. A média etária dos pacientes foi 56,9 anos, com extremos de 25 e 87 anos, sendo as sexta e sétima décadas a mais representativa, respectivamente com 25,6% e 24,8%, totalizando 50,4% dos 55 pacientes (p<0,05). Dos 129 pacientes, 51,2% eram sexo feminino (51,2%) (p>0,05). A entidade nosológica mais comum foi o câncer colorretal (74 casos; 57,4%), seguindo as ileostomias (16 casos; 12,4%) e as complicações cirúrgicas (11 casos; 8,5%). As cirurgias mais realizadas foram as retossigmoidectomia com anastomose colorretal (35 casos; 27,1%), as hemicolectomias direitas com anastomose ileo-transverso (20 casos; 15,5%) e o restabelecimento de trânsito intestinal de ileostomia (16 casos;12,4%). Das 129 cirurgias 53 (41,1%) não envolveram anastomoses e 76 (58,9%) envolveram ressecções intestinais e anastomoses. Houve oito co-morbidades (6,2%), sendo a caquexia (três casos) a mais comum. Houve 17 complicações (13,2%), 11 envolvendo as 76 ressecções com anastomose (14,5%) e seis as ressecções sem anastomoses (11,3%). As complicações mais comuns entre as 11 provenientes de ressecções e anastomoses foram as deiscências (sete; 9,2%). As anastomoses mecânicas (55) complicaram mais (16,3%) que as manuais (21) (9,5%). Houve 14 óbitos (10,8%), sendo seis (4,6%) devidos à sepse, quatro (3,1%) devido a TEP e quatro (3,1%) devido a falência múltipla de órgãos. Dos 14 óbitos, quatro (3,1%) foram decorrentes de complicações cirúrgicas e dez (7,7%) foram decorrentes de co-morbidades.

In the framework of postgraduate Coloproctology for the year 2009, the two graduate students conducted the second year as principal surgeons, 129 major surgeries, always assisted effectively by one or two tutors. All surgeries were performed on public patients in Santa Casa de Belo Horizonte, with absolute presence of members of the Coloproctology Unit of Santa Casa School of Medical Sciences of Minas Gerais (GCP-CBHS-FCMMG). A retrospective analysis of 129 medical records was carried out, allowing several important observations. The average age of patients was 56.9 years, with extremes of 25 and 87 years, while the sixth and seventh decades the most representative, with respectively 25.6% and 24.8% to 50.4% of 55 patients (p <0.05). Most of the 129 patients were female (51.2%) (p> 0.05). The most common nosological entity was colorectal cancer (74 cases, 57.4%), following the ileostomies (16 cases, 12.4%) and surgical complications of previous surgeries (11 cases, 8.5%). The most commonly performed procedures were abdominal rectosigmoidectomy with colorectal anastomosis (35 cases, 27.1%), the right hemicolectomy with ileo-transverse anastomosis (20 cases, 15.5%) and the resumption of intestinal transit of ileostomy (16 cases, 12, 4%). Of 129 surgeries 53 (41.1%) did not involve anastomosis and 76 (58.9%) involved intestinal resection and anastomosis. There were eight co-morbidities (6.2%) and cachexia (three cases) the most common. There were 17 complications (13.2%), 11 involving the 76 resections with anastomosis (14.5%) and six resections without anastomosis (11.3%). The most common complications among the 11 patients from resection and anastomosis were dehiscence (seven, 9.2%). The mechanical anastomosis (55) developed more complications (16.3%) than handmade anastomosis (21) (9.5%). There were 14 deaths (10.8%), six (4.6%) due to sepsis, four (3.1%) due to pulmonary thromboembolic disease and four (3.1%) due to multiple organ failure. Of the 14 deaths, four (3.1%) were due to surgical complications and ten (7.7%) were due to co-morbidities.

Investigar o percentual de detecção de tuberculose entre sintomáticos respiratórios é o objetivo do presente estudo. Nesta nota prévia, apresentam-se os resultados preliminares da pesquisa desenvolvida no Hospital das Clinicas de Teresópolis Costantino Ottaviano da Fundação Educacional Serra dos Órgãos (FESO), de novembro de 2003 a abril de 2004. Dos 40 sintomáticos respiratórios identificados e encaminhados ao Programa de Controle da Tuberculose do município de Teresópolis, dois (5.0%) foram caracterizados como bacilíferos. Esses resultados corroboram com os relatos da literatura e confirmam a necessidade e importância desta estratégia.

The aim of the present study was to investigate the detection percentage of tuberculosis among patients that are respiratory symptomatic (TB suspects). In this work, we present the preliminary results of research carried out at "Hospital das Clínicas de Teresópolis Costantino Ottaviano da Fundação Educacional Serra dos Órgãos (FESO)" from November 2003 to April 2004. Among the 40 respiratory symptomatic individuals identified and referred to the Tuberculosis Control Program in Teresópolis, two (5.0%) were characterized as smear-positive. These results confirm reports in the literature and underscore the need for and importance of this strategy.

Paciente do sexo masculino, 49 anos, atendido na Emergência do Real Hospital Português de Beneficência (RHPBPE), após acidente automobilístico, apresentando dispnéia, fraturas de múltiplos arcos costais, enfisema subcutâneo extenso e hidropneumotórax à esquerda e fratura da clavícula direita. Submetido inicialmente à drenagem torácica subaquática à esquerda e traqueostomia, tendo sido mantido em respiração controlada no respirador de volume na Unidade de Terapia Intensiva. Recebeu alta após um mês da admissão com ecocardiograma transtorácico que mostrava insuficiência aórtica e insuficiência mitral leve, com leve aumento das câmaras cardíacas esquerdas, com função global preservada, não se relacionando os achados ao trauma. Após três meses, retornou à Emergência cardiológica do mesmo Hospital com sinais e sintomas de insuficiência cardíaca congestiva. Submetido a ecocardiograma transtorácico e transesofágico que mostraram insuficiência aórtica grave e septo interatrial pérvio. À exploração cirúrgica encontramos a desinserção da cúspide não coronariana e ruptura do septo interatrial. A tentativa de reinserir a cúspide não permitiu uma coaptação completa da valva aórtica, optando-se por sua substituição com implante de uma prótese metálica St. Jude número 23. A ruptura do septo interatrial foi corrigida por aproximação direta com pontos separados. O paciente recebeu alta no 9º dia de pós-operatório, sem intercorrências e assintomático.

The case of a 49-year-old man who suffered a car accident responsible for several chest injuries including fractures of the left ribs, large subcutaneous emphysema and left hemopneumothorax arrived in shock in the Emergency Room of the Real Hospital Português de Beneficência in Pernambuco (RHPBPE). He was hospitalized for 30 days including some time in the intensive care unit and but did not show signs of diastolic murmur or heart failure. He was submitted to an echocardiography examination that diagnosed slight aortic incompetence, good left ventricular function and was discharged after clinical improvement. Three months later he started to feel symptoms of heart failure and returned to cardiac Emergency Room of the same Hospital. He repeated transthoracic and transesophageal echocardiography examinations presenting severe aortic incompetence due to leaflet disruption, rupture of atrial septum with enlargement of the right cardiac chambers and poor left ventricular function. He underwent surgical treatment of these lesions, with direct approach of the atrial septum and the aortic valve was replaced with a mechanical prosthesis, with a good result.
