RESUMO Contexto: A litíase biliar pode ser definida como a presença de cálculo ou barro biliar na vesícula e/ou nos ductos biliares. A doença pode ser assintomática ou sintomática, podendo levar a complicações e, consequentemente, a um pior prognóstico, como colecistite aguda, coledocolitíase, colangite e pancreatite aguda. O risco de complicações aumenta após o primeiro episódio de cólica biliar. Objetivo: Avaliação clínica-epidemiológica dos pacientes internados em enfermaria de gastroenterologia de um hospital terciário, com complicações relacionadas à litíase biliar. Métodos: Foram avaliados 158 pacientes internados no período de 1º de janeiro de 2013 a 24 de fevereiro de 2021, por meio de análise de relatório de alta e prontuário. Resultados: Houve uma predominância do sexo feminino (76,6%), e a média de idade dos pacientes foi de 51,6 anos. Homens eram significativamente mais velhos que as mulheres (P=0,005). A maioria (57,6%) apresentava alguma comorbidade, sendo as mais frequentes: hipertensão arterial sistêmica, diabetes mellitus e obesidade. A média de tempo de internação foi de 24 dias, sendo significativamente maior para os homens (P=0,046), mas sem relação direta com a idade (P=0,414). A complicação mais frequente foi a coledocolitíase, e 55,7% dos pacientes sem colecistectomia prévia apresentaram relato de cólica biliar antes da internação, em média, 1,5 anos antes. Histórico de colecistectomia prévia estava presente em 17,1% dos avaliados. Ultrassonografia abdominal, seguida de colangiorressonância magnética foram os exames complementares mais frequentemente realizados para definição diagnóstica. Em relação às medidas terapêuticas, a colangiopancreatografia endoscópica retrógrada (CPRE) foi necessária em 47,3% dos pacientes sem colecistectomia prévia e 81,4% dos pacientes com colecistectomia prévia. Dos pacientes ainda não colecistectomizados, 84% deles puderam ser submetidos ao procedimento antes da alta. Conclusão: Houve predomínio do sexo feminino. Os homens foram significativamente mais velhos do que as mulheres e tiveram uma permanência hospitalar consideravelmente mais longa. A complicação mais frequente foi a coledocolitíase, e cerca de metade dos pacientes relatou cólica biliar prévia. A CPRE foi necessária para a maioria dos pacientes.

ABSTRACT Background: Gallstones are the presence of bile clay in the gallbladder or bile ducts. The disease can be asymptomatic or symptomatic and can lead to complications and consequently a worse prognosis, such as acute cholecystitis, choledocholithiasis, cholangitis, and acute pancreatitis. The risk of complications increases after the first episode of biliary colic. Objective: A clinical-epidemiological evaluation of patients admitted to a gastroenterology ward of a tertiary care hospital with gallstone-related complications. Methods: We evaluated 158 patients admitted through discharge reports and medical records analysis from January 1, 2013, to February 24, 2021. Results: The female sex was predominant (76.6%), and the mean age of patients was 51.6 years. Men were significantly older than women (P=0.005). Most (57.6%) had some comorbidity, the most frequent being systemic arterial hypertension, diabetes mellitus, and obesity. The mean hospitalization time was 24 days, significantly longer in men (P=0.046) but without a direct relationship with age (P=0.414). The most frequent complication was choledocholithiasis, and 55.7% of patients without previous cholecystectomy had a report of biliary colic before admission, on average 1.5 years previously. A history of a prior cholecystectomy was present in 17.1% of those evaluated. Abdominal ultrasonography followed by magnetic resonance cholangiography was the most frequently performed exam for diagnostic definition. Regarding therapeutic measures, endoscopic retrograde cholangiopancreatography was necessary for 47.3% of patients without previous cholecystectomy and 81.4% of patients who have already had a cholecystectomy. Among patients not yet cholecystectomized, 84% underwent the procedure before discharge. Conclusion: The female patients were predominant. Men were significantly older than women and had more extended hospital stays. The most frequent complication was choledocholithiasis, and around half of the patients reported previous biliary colic. endoscopic retrograde cholangiopancreatography has been necessary for the majority of the patients.

Abstract Paper aims This paper analyzes Command and Control (C2) Systems and identifies the level of knowledge on the subject by actors involved in disaster response operations in Brazil, besides assessing the evolution in this area since the disaster of the Serrana Region of Rio de Janeiro in 2011. Originality The concept of C2 is still little explored academically, especially in disaster management systems. This study contributes to the understanding of the dynamics of different C2 Systems operated in Brazil, as well as identifying the level of knowledge on the subject and its evolution since 2011. Research method This is an exploratory survey in which data was analyzed using descriptive statistics techniques. Main findings We conclude that the actors involved in real disaster situations have little formal training in C2. The findings indicate that the performance of a simulated exercise helps in disaster preparedness, but the participants observed deficiencies concerning C2 training besides the lack of local community involvement in the simulated exercise. Implications for theory and practice This study contributes to the disaster management literature, showing empirical evidence that the results obtained in a simulated exercise can boost the specialization of professionals in C2 systems in the area of disasters.

OBJECTIVES: This study aimed to correlate a higher Pelvic-Trochanteric Index (PTI) with an increased varus of the femoral neck with greater trochanteric pain syndrome (GTPS). The secondary objective was to check whether the pelvic width changes with age. METHODS: A prospective study was conducted to compare female patients diagnosed with GTPS (case group) with asymptomatic female participants (control group) from March 2011 to June 2017. On an anteroposterior pelvic radiograph, lines were drawn by two radiologists, and the PTI (ratio of the distance between the greater trochanters and distance between the iliac crests) was defined and the femoral neck-shaft angle was measured. RESULTS: Data collected based on radiographs of 182 female patients (cases) and 150 female participants (controls) showed that the mean PTI was 1.09 (SD=0.01) in the case group and 1.07 (SD=0.01) in the control group (p<0.05), regardless of age. The distance between iliac crests increased with age (p<0.05) in symptomatic and asymptomatic individuals. It was also found that the mean femoral neck-shaft angle was 130.6° (SD=0.59) and progression of the varus angulation occurred with age in both groups, with a significance level of 5%. CONCLUSIONS: The PTI was higher in patients with GTPS. The femoral neck-shaft angle does not differ between individuals with and without GTPS; however, it does decrease with age. The pelvic width tends to increase with aging in symptomatic or asymptomatic individuals; therefore, the increase in the pelvic width and decrease in the femoral neck-shaft angle can be interpreted as normal in aging women, which could alter the biomechanics of the hips and pelvis.

RESUMO Objetivo Avaliar o efeito da indução de danos ao DNA em células monocelulares do sangue periférico de pacientes com doença falciforme, genótipos SS e SC, tratados com hidroxiureia. Métodos Os sujeitos da pesquisa foram divididos em dois grupos: um de 22 pacientes com doença falciforme genótipos SS e SC tratados com hidroxiureia, e o outro controle, composto por 24 pacientes com doença falciforme que não eram tratados com o fármaco. As amostras de sangue periférico foram submetidas ao isolamento de células mononucleares do sangue periférico para avaliação da genotoxicidade pelo ensaio de micronúcleo citoma com bloqueio da citocinese, tendo sido quantificados os biomarcadores de danos ao DNA – micronúcleos, pontes nucleoplasmáticas e brotamento nuclear. Resultados Os pacientes com doença falciforme tratados com hidroxiureia apresentaram média de idade de 25,4 anos, enquanto aqueles com doença falciforme não tratados com hidroxiureia tiveram média de idade de 17,6 anos. A dose média de hidroxiureia utilizada pelos pacientes foi de 12,8mg/kg/dia, por período médio de 44 meses. A frequência média de micronúcleos por 1.000 células de 8,591±1,568 foi observada no Grupo Hidroxiureia e de 10,040±1,003 no Grupo Controle. Adicionalmente, a frequência média de pontes nucleoplasmáticas por 1.000 células e brotamento nuclear por 1.000 células para o Grupo Hidroxiureia e Controle foi de 0,4545±0,1707 versus 0,5833±0,2078, e de 0,8182±0,2430 versus 0,9583±0,1853, respectivamente. Não houve diferença estatisticamente significativa entre os grupos. Conclusão Na população estudada de pacientes com doença falciforme com tratamento em dose padrão de hidroxiureia, não houve evidência de indução de danos ao DNA.

ABSTRACT Objective To evaluate the induction of DNA damage in peripheral blood mononuclear cells of patients with sickle cell disease, SS and SC genotypes, treated with hydroxyurea. Methods The study subjects were divided into two groups: one group of 22 patients with sickle cell disease, SS and SC genotypes, treated with hydroxyurea, and a Control Group composed of 24 patients with sickle cell disease who were not treated with hydroxyurea. Peripheral blood samples were submitted to peripheral blood mononuclear cell isolation to assess genotoxicity by the cytokinesis-block micronucleus cytome assay, in which DNA damage biomarkers – micronuclei, nucleoplasmic bridges and nuclear buds - were counted. Results Patients with sickle cell disease treated with hydroxyurea had a mean age of 25.4 years, whereas patients with sickle cell disease not treated with hydroxyurea had a mean age of 17.6 years. The mean dose of hydroxyurea used by the patients was 12.8mg/kg/day, for a mean period of 44 months. The mean micronucleus frequency per 1,000 cells of 8.591±1.568 was observed in the Hydroxyurea Group and 10.040±1.003 in the Control Group. The mean frequency of nucleoplasmic bridges per 1,000 cells and nuclear buds per 1,000 cells for the hydroxyurea and Control Groups were 0.4545±0.1707 versus 0.5833±0.2078, and 0.8182±0.2430 versus 0.9583±0.1853, respectively. There was no statistically significant difference between groups. Conclusion In the study population, patients with sickle cell disease treated with the standard dose of hydroxyurea treatment did not show evidence of DNA damage induction.

Abstract Objective: The disease of the aortic arch is traditionally approached by open surgical repair requiring cardiopulmonary bypass and circulatory arrest. This study performed a retrospective analysis comparing outcomes through primary hybrid patients submitted to aortic arch surgery without cardiopulmonary bypass with patients submitted to conventional open surgery. Methods: 25 patients submitted to the aortic arch surgery were selected in the period 2003-2012 at the Madre Teresa Hospital in the city of Belo Horizonte, Brazil; 13 of these underwent hybrid technique without cardiopulmonary bypass and 12 underwent conventional open surgery. Results: The mortality rate for the hybrid group was 23% and for the conventional surgery group was 17% (P=0.248). The postoperative complication rate was also similar in both groups, with no significant difference. Conclusion: Both techniques proved to be similar in mortality and morbidity. However, due to the small sample, more analytical studies with larger samples and long-term follow-up are needed to clarify this issue.

RESUMO Objetivo: Determinar a especificidade, sensibilidade, acurácia, razão de verossimilhança e correlação dos achados dos testes meniscais e da ressonância magnética (RM) com a videoartroscopia do joelho. Métodos: Estudo transversal feito entre junho e dezembro de 2015. Avaliaram-se 84 pacientes selecionados para tratamento videoartroscópico das lesões meniscais (LM). Dois ortopedistas especializados em cirurgia do joelho e um residente em ortopedia fizeram o exame físico com testes específicos. Os resultados obtidos e laudos da RM foram comparados com os achados da videoartroscopia. Os dados foram tratados no programa estatísticoR. Resultados: O teste de Steinmann I, foi mais específico, com especificidade de 86% e 91% para lesões de menisco medial (LMM) e lesões de menisco lateral (LML), respectivamente. Quanto à acurácia, o teste de dor à palpação da interlinha articular (DPIA) apresentou valores de 67% e 73% para detecção de LMM e LML, respectivamente. O teste de DPIA apresentou maior sensibilidade, com 77% de chance de detectar LMM. A análise do conjunto de três testes (McMurray, DPIA e Steinmann I, ) comparada com a videoartroscopia apresentou 85% de sensibilidade para as LMM e 70% de sensibilidade para as LML. A RM apresentou maior especificidade para o diagnóstico de LMM e LML; 82% e 91%, respectivamente.. Conclusão: O conjunto dos três testes apresentou melhores resultados se comparado com os testes isolados e pode ser associado à RM para elaboração de um diagnóstico efetivo. Entretanto, são necessários outros estudos que auxiliem na elaboração de um protocolo para padronizar a avaliação diagnóstica.

ABSTRACT Objective: To determine the specificity, sensitivity, accuracy, likelihood, and correlation of the findings of meniscal tests and magnetic resonance imaging (MRI) to knee video arthroscopy., Methods: A cross-sectional study, conducted between June and December 2015, which evaluated 84 patients with meniscal tears (MT) selected for video arthroscopy. Two orthopedic trainees and a resident performed a physical examination with specific tests. The results and reports from MRI were compared with arthroscopy findings. The data were analyzed in the statistical program , R. Results: The Steinmann I, test was the most specific, with specificity of 86% and 91% for medial meniscus tears (MMT) and lateral meniscus tears (LMT), respectively. With regard to accuracy, the pain test on palpation of the joint interline (PPJI) showed values of 67% and 73% for detection of MMT and LMT, respectively. The PPJI test showed higher sensitivity, with a 77% chance of detecting MMT. Analysis of the set of three tests (McMurray, PPJI, and Steinmann , I, ) compared to arthroscopy showed 85% sensitivity for MMT and 70% sensitivity for LMT. MRI showed a greater specificity for the diagnosis of MMT and LMT; the values were 82% and 91%, respectively. Conclusion: The combination of the three tests shows better results compared to the isolated tests and thus can be associated to the MRI to make an effective diagnosis. However, further studies assisting in the development of a protocol to standardize diagnostic evaluation are required.
