Objective: to analyze the problematization methodology impact on the knowledge of nursing and medical students about hypodermoclysis. Method: quasi-experimental study conducted with 22 undergraduate nursing and medical students from a public Brazilian higher education institution. The students participated in the educational intervention using the problematization methodology based on the Arch of Maguerez. A previously validated questionnaire was used to determin’ the students’ knowledge level about hypodermoclysis. This instrument was applied before and after the educational intervention. The results were compared by McNemar’s test and Student’s t test for paired samples. Results: when comparing the correct answers before and after the intervention, there was a significant increase in 75% of the questions (p<0.05), including theoretical and practical aspects of hypodermoclysis. The mean score on students’ self-assessment of the ability to explain (0.9 versus 5.9 points) and perform hypodermoclysis (1.9 versus 5.0) was significantly higher after applying the problematization methodology (p<0.001). Conclusion: the problematization methodology had a positive impact on the students’ knowledge about hypodermoclysis. The number of correct answers after the educational intervention was higher than the initial assessment. The problematization methodology can be incorporated into the teaching-learning process of nursing and medical students for teaching procedures such as hypodermoclysis.

BACKGROUND Dengue is a disease caused by dengue virus (DENV-1 through -4). Among the four serotypes, DENV-4 remains the least studied. Acute kidney injury is a potential complication of dengue generally associated with severe dengue infection. OBJECTIVES The goal of this study was to investigate the alterations caused by experimental dengue infection in the kidney of adult BALB/c mice. METHODS In this study, BALB/c mice were infected through the intravenous route with a DENV-4 strain, isolated from a human patient. The kidneys of the mice were procured and subject to histopathological and ultrastructural analysis. FINDINGS The presence of the viral antigen was confirmed through immunohistochemistry. Analysis of tissue sections revealed the presence of inflammatory cell infiltrate throughout the parenchyma. Glomerular enlargement was a common find. Necrosis of tubular cells and haemorrhage were also observed. Analysis of the kidney on a transmission electron microscope allowed a closer look into the necrotic tubular cells, which presented nuclei with condensed chromatin, and loss of cytoplasm. MAIN CONCLUSIONS Even though the kidney is probably not a primary target of dengue infection in mice, the inoculation of the virus in the blood appears to damage the renal tissue through local inflammation.

INTRODUÇÃO: A depressão durante ou logo após a hospitalização, eleva duas a três vezes o risco de mortalidade ou eventos cardíacos não-fatais, aumentando sensivelmente a morbimortalidade desses pacientes. OBJETIVO: Avaliar o impacto da revascularização do miocárdio nos sintomas de depressão de pacientes portadores de doença arterial coronariana. MÉTODOS: Estudo de coorte prospectivo de 57 pacientes de ambos os sexos, submetidos à revascularização do miocárdio, entre junho de 2010 e junho de 2011. Foram utilizados os questionários SF-36 para avaliar a qualidade de vida, e o Inventário de Depressão Beck para detectar sintomas depressivos, aplicados no pré-operatório e após seis meses. RESULTADOS: A prevalência de pacientes na faixa etária de 60 a 69 anos foi de 22 (38,60%) pacientes, 39 (68,42%) homens, 26(45,61%) autodeclarados pardos, 16 (28,07%) alfabetizados e 30 (52,63%) casados. O escore Inventário de Depressão Beck demonstrou aumento após a revascularização de 15 (26,32%) pacientes em grau leve no momento zero para 17 (29,82%) após. E com grau moderado, sete (12,28%) pacientes antes e 10 (17,54%) após. Nas categorias de indivíduos com grau mínimo houve redução de 32 (56,14%) para 28 (49,12%) e grave de três (5,26%) para dois (3,51%) pacientes. Observou-se associação entre Inventário de Depressão Beck, sexo, idade, estilo de vida, comorbidades e a qualidade vida. CONCLUSÃO: Observou-se elevada prevalência de escores elevados de inventário de depressão Beck, piores escores de sintomas depressivos entre homens e associação entre a melhoria dos escores de qualidade de vida e o Inventário de Depressão Beck.

INTRODUCTION: Depression during or shortly after hospitalization elevated two to three times the risk of mortality or nonfatal cardiac events, significantly increasing the morbidity and mortality of these patients. OBJECTIVE: To assess the impact of revascularization on symptoms of depression in patients with coronary artery disease. METHODS: A prospective cohort study of 57 patients of both sexes undergoing coronary artery bypass grafting between June 2010 and June 2011. We used the SF-36 to assess quality of life, and the Beck Depression Inventory to detect depressive symptoms, applied preoperatively and six months. RESULTS: The prevalence of patients aged 60-69 years was 22 patients (38.60%), 39 men (68.42%), 26 described themselves as mixed race (45.61%), 16 literate (28.07 %) and 30 married (52.63%). The beck depression inventory score demonstrated increased after revascularization: 15 patients mild (26.32%) at time zero to 17 (29.82%) after. And with moderate, seven patients (12.28%) before and 10 (17.54%) after. In the categories of individuals with decreased minimum degree of 32 (56.14%) to 28 (49.12%), and severe of three (5.26%) for two (3.51%) patients. Association was observed between beck depression inventory, gender, age, lifestyle, comorbidities and quality of life. CONCLUSION: There was a high prevalence of elevated beck depression inventory scores, lowest scores of depressive symptoms among men and association between the improvement of quality of life scores and beck depression inventory.

Most cases of sporadic primary hyperparathyroidism present disturbances in a single parathyroid gland and the surgery of choice is adenomectomy. Conversely, hyperparathyroidism associated with multiple endocrine neoplasia type 1 (hyperparathyroidism/multiple endocrine neoplasia type 1) is an asynchronic, asymmetrical multiglandular disease and it is surgically approached by either subtotal parathyroidectomy or total parathyroidectomy followed by parathyroid auto-implant to the forearm. In skilful hands, the efficacy of both approaches is similar and both should be complemented by prophylactic thymectomy. In a single academic center, 83 cases of hyperparathyroidism/ multiple endocrine neoplasia type 1 were operated on from 1987 to 2010 and our first surgical choice was total parathyroidectomy followed by parathyroid auto-implant to the non-dominant forearm and, since 1997, associated transcervical thymectomy to prevent thymic carcinoid. Overall, 40% of patients were given calcium replacement (mean intake 1.6 g/day) during the first months after surgery, and this fell to 28% in patients with longer follow-up. These findings indicate that several months may be needed in order to achieve a proper secretion by the parathyroid auto-implant. Hyperparathyroidism recurrence was observed in up to 15% of cases several years after the initial surgery. Thus, long-term follow-up is recommended for such cases. We conclude that, despite a tendency to subtotal parathyroidectomy worldwide, total parathyroidectomy followed by parathyroid auto-implant is a valid surgical option to treat hyperparathyroidism/multiple endocrine neoplasia type 1. Larger comparative systematic studies are needed to define the best surgical approach to hyperparathyroidism/multiple endocrine neoplasia type 1.

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.

O transplante de células-tronco hematopoéticas (TCTH) é o tratamento de escolha para leucemias agudas de alto risco. Apesar da melhora na sobrevida destes pacientes, a recidiva continua sendo a maior causa de óbito pós-transplante de células-tronco hematopoéticas. O objetivo deste trabalho foi analisar os resultados dos transplantes realizados em crianças com leucemia aguda em duas instituições brasileiras. Realizou-se estudo retrospectivo de 208 pacientes transplantados entre 1990-2007. Mediana de idade: 9 anos; 119 pacientes com leucemia linfoide aguda (LLA) e 89 com leucemia mieloide aguda (LMA). Doença precoce: CR1 e CR2. Doença avançada: >CR3, doença refratária ou recidivada. Noventa pacientes vivos entre 258-6.068 dias (M:1.438), com sobrevida global (SG) de 45% (3 anos) e a sobrevida livre de recaída (SLR) 39% (três anos). 14/195 pacientes tiveram falha primária de pega (8%). Não houve diferença na sobrevida global e sobrevida livre de recaída entre pacientes com leucemia linfoide aguda e leucemia mieloide aguda, entre transplantes aparentados e não aparentados, tampouco entre as fontes de células utilizadas. O desenvolvimento da doença do enxerto contra hospedeiro (DECH) aguda ou crônica também não influenciou a sobrevida global e sobrevida livre de recaída. Pacientes com leucemia linfoide aguda condicionados com irradiação corporal total (TBI) apresentaram melhor sobrevida global e sobrevida livre de recaída (p<0,001). Cento e dezoito pacientes morreram entre 1-1.654 dias pós-transplante de células-tronco hematopoéticas (M:160). Mortalidade relacionada a transplante (MRT) (dia+100): 16%. Incidência cumulativa de recaída: 40% (3 anos). Pacientes com doença avançada tiveram menor sobrevida global e sobrevida livre de recaída (três anos)(p<0,001). Na análise multivariada, o status da doença foi o principal fator associado ao aumento da sobrevida global e sobrevida livre de recaída. Nossos resultados mostram que é possível se atingir uma boa sobrevida para pacientes com doença precoce e também mostram a baixa eficácia naqueles com doença avançada.

Hematopoietic Stem Cell transplantation (HSCT) is the treatment of choice for patients with high-risk leukemia. In spite of this, relapse remains a major cause of death of these patients. Our objective was to analyze the outcomes of patients with acute leukemia submitted to hematopoietic stem cell transplantation in two Brazilian institutions. A retrospective study of 208 patients transplanted between 1990 and 2007 with a median age of 9 years (range: 1-18 years) was made. One hundred and nineteen patients had acute lymphocytic leukemia (ALL) and 89 had acute myeloid leukemia (AML). Early disease was considered for CR1 and CR2 cases and advanced disease >CR3 and refractory and relapse disease. Ninety patients are alive between 258 and 6068 days after hematopoietic stem cell transplantation (M: 1438 days). The overall survival (OS) was 45% (3 years) and event free survival (EFS) was 39% (3 years). Primary graft failure occurred in 14/195 patients (8%). There were no differences in the overall survival and event free survival between patients with acute lymphocytic leukemia and acute myeloid leukemia, between sources of cells used or between those who developed acute or chronic graft-versus-host disease (GVHD). When comparing transplants from related and unrelated donors, there was no difference in the overall survival. Patients with acute lymphocytic leukemia receiving the total body irradiation (TBI) conditioning regimen had better overall survival and event free survival (p<0.001). One hundred and eighteen patients died between 0 and 1654 days after hematopoietic stem cell transplantation (M: 160 days). Transplantation-related-mortality (TRM) at D+100 was 16% and cumulative incidence of relapse was 40% (3 years). Patients with advanced disease had lower 3-year overall survival and event free survival (p<0.001). Multivariate analysis showed that disease status was the most significant factor associated with higher event free survival and overall survival . Our results show that children and adolescents transplanted with early disease can achieve considerable overall survival and also highlights the inefficacy of hematopoietic stem cell transplantation for patients with advanced disease.

OBJETIVOS: Realizar rastreamentos clínico e gênico para Neoplasia Endócrina Múltipla tipo 1 (NEM1) e analisar seu impacto no seguimento clínico desses pacientes no Hospital das Clínicas, SP. MÉTODOS: O diagnóstico clínico de NEM1 foi realizado de acordo com o Consenso sobre neoplasias endócrinas múltiplas. A análise genética para identificação de mutações foi realizada por sequenciamento automático de todas as regiões codificadoras e fronteiras exon/intron do gene MEN1. Os casos afetados foram sub-divididos em 3 grupos e analisados separadamente: casos-índices (grupo I), familiares diagnosticados clinicamente (grupo II) e genicamente (grupo III). RESULTADOS: Um total de 154 casos participou desse estudo, sendo 52 diagnosticados com NEM1: 13 do grupo I, 28 do grupo II e 11 do grupo III. A idade média ao diagnóstico no grupo III (27 anos) foi significativamente menor que a dos grupos I (39,5 anos; p = 0,03) e II (42,4 anos; p = 0,01). A maioria dos pacientes dos grupos I e II apresentou 2 ou 3 tumores, enquanto que 81,8% dos casos do grupo III apresentavam 1 ou nenhum tumor relacionado à NEM1. Além disto, 45,4% dos casos do grupo III eram assintomáticos, não sendo observados nenhuma metástase ou óbito. Os demais 102 familiares sob-risco estudados não herdaram mutação MEN1 e foram excluídos do rastreamento clínico. Um caso de fenocópia NEM1 foi também localizado. DISCUSSÃO: Nossos dados demonstraram importantes benefícios no seguimento dos pacientes NEM1, obtidos pela implementação dos rastreamentos clínico e gênico para essa doença.

PURPOSE: To perform clinical and genetic screening for multiple endocrine neoplasia type 1 (MEN1) in patients at the Academic Hospital of the University of São Paulo School of Medicine, and to analyze its impact on clinical management of patients with MEN1. METHODS: The clinical diagnosis of MEN1 was made in accordance with the Consensus on multiple endocrine neoplasias. Mutation analysis of the entire MEN1 tumor suppressor gene and genetic screening of at-risk family members were performed by direct sequencing. To analyze the implementation of genetic diagnosis, the studied patients were separated into 3 groups: MEN1 index cases (group I), clinically diagnosed MEN1 cases (group II), and genetically diagnosed MEN1 cases (group III). RESULTS: In total, 154 individuals were clinically and genetically studied. We identified 12 different MEN1 mutations. Fifty-two MEN1 cases were identified: 13 in group I, 28 in group II, and 11 in group III. The mean age in group III (27.0 years) was significantly lower than in groups I (39.5 years) and II (42.4 years; P = 0.03 and P = 0.01, respectively). Patients in groups I and II mostly presented 2 or 3 MEN1-related tumors, while 81.8% of those in group III presented 1 or no MEN1-related tumor. Additionally, in group III, 45.4% of cases were asymptomatic, and no metastasis or death was verified. Surveillance for MEN1 mutations allowed the exclusion of 102 noncarriers, including a case of MEN1 phenocopy. CONCLUSION: Our data supports the benefits of clinical and genetic screening for multiple endocrine neoplasia type 1 in the management of this syndrome.
