RESUMO

Background: Temporal muscle has great versatility to cover defects, caused by resections or large soft tissue losses of the middle facial third, has been used for more than 100 years. In the skin, the temporal muscle is transformed by the phenomenon called skin dermalization and mucolization in the oral cavity. Purpose: This article shows how the temporal muscle is divided into two segments (bipartition) or three segments (tripartition) achieving a transposition of the muscle to cover large empty spaces caused by orbital exenteration or in maxilectomy. In coronal slice tomography, we demonstrate the perfect adaptation of the temporal muscle to the periorbital soft tissues in 360 degrees of the orbital region. In the defect produced by the maxilectomy, a perfect seal is obtained to achieve the separation of the nasal cavity from the oral cavity. Methods: The treatment was carried out in 3 immunocompromised adult patients, who presented mucormycosis of the middle third of the face and could not swallow or feed. Results: The result we have in the survival of rhinocerebral mucormycosis is very high, due to extensive resections. Achieving that the patient has an adequate swallowing. Conclusion: We consider that the treatment is excellent due to the proximity of the temporal muscle to the surgical defect, achieving the objective of reconstruction without rejection.

RESUMO

BACKGROUND: Single anastomosis sleeve ileal (SASI) Bypass has recently emerged as a novel surgical technique. The purpose of this study is evaluating the efficacy and feasibility of our SASI technique. METHODS: Between April 2018 and February 2020, 83 patients underwent SASI bypass at our center. A retrospective analysis was performed. Forty-three patients (51.8%) completed follow-up at 12 months. RESULTS: Average BMI at 12 months, change in BMI, and %EWL were 28.2 ± 4.5 kg/m2, 13.5 ± 5.7 kg/m2, and 85.6% respectively. From the 25 patients evaluated, diabetes remission occurred in 95.8% of them. There were 4 (4.8%) Clavien-Dindo (CD) I, 5 (6.0%) CD II, and 2 (2.4%) CD IIIb complications. CONCLUSIONS: SASI bypass offers excellent weight loss and comorbidities resolution. As expected, higher-quality studies are needed.

RESUMO

INTRODUCTION: Epidemiological data have demonstrated that obesity is an important risk factor for the development of gastroesophageal reflux disease (GERD). The proportion of subjects with GERD symptoms can be as high as 50% for BMI > 30. Although still controversial in the literature, there are several studies associating sleeve gastrectomy (SG) with an increase in GERD prevalence. The current video shows the technique of a SG with cardioplication associated with transit bipartition (TB) for the treatment of an obese patient with severe GERD. CASE REPORT AND MANAGEMENT: A 46-year-old male presented with obesity and GERD symptoms for several years. His BMI was 37.8 kg/m2 with mainly central obesity and several obesity-related comorbidities, including hypertension, dyslipidemia, severe insulin resistance, and obstructive sleep apnea. After a diagnostic evaluation, the patient was submitted to a sleeve gastrectomy with a transit bipartition. He presented satisfactory weight loss, reaching a BMI of 26 and remission of all comorbidities and complete remission of GERD symptoms. The current follow-up period is 2.5 years and the patient did not present any weight regain or return of the GERD symptoms. CONCLUSION: We presented a surgical alternative that is effective in both weight loss and remission of GERD. SG + TB is a potent intervention for metabolic syndrome and obesity. Furthermore, this alternative is capable of treating both obesity and GERD, in a simple way, avoiding mechanical restriction and the significant malabsorption related to excluded segments.

RESUMO

O objetivo do estudo foi avaliar a influência da bipartição escrotal sobre a capacidade de termorregulação do testículo caprino, testando-se a hipótese de que animais com bipartição possuem menor temperatura testicular, maior capacidade hemodinâmica local, maior número de células germinativas e maior produção espermática. Foram selecionados 8 bodes, divididos de acordo com a conformação escrotal: G1 (n=4) animais com até 50% de bipartição; GC (n=4) grupo controle, sem bipartição. Todos foram submetidos à mensuração da temperatura retal, termografia corporal e escrotal. Exames ultrassonográficos Doppler foram conduzidos no plexo pampiniforme. Adicionalmente os animais foram submetidos à punção biópsia aspirativa testicular (PBA) e 2 ejaculados de cada reprodutor foram colhidos para avaliação espermática. Não foram observadas diferenças para os resultados da PBA, da termografia escrotal e do espermograma comparando-se os dois grupos. Na avaliação hemodinâmica apenas o IR (0,53a+-0,11 e 0,46b+- 0,06; p=0,0108) foi superior para os animais bipartidos. Conclui-se que caprinos que possuem até 50% de bipartição escrotal possuem qualidade espermática semelhante a animais não bipartidos, não possuem menor temperatura testicular e maior número de células germinativas primordiais como se supunha na hipótese inicial da pesquisa.(AU)

The objective of this study was to evaluate the influence of the bipartition of the scrotum on the thermoregulatory capacity of the goat testicle, testing the hypothesis that bucks with bipartition of the scrotum have minor testicular temperature, greater local hemodynamic capacity, more germ cells and higher sperm production capacity. Eight male goats were used and divided according to the conformation of the scrotum: G1 (n=4) animals with scrotal bipartition below 50%; CG (n=4) control group without scrotal bipartition. All the animals were submitted to the evaluation of rectal temperature and scrotal and body surface thermography. Doppler ultrasonography held at the spermatic cord region was performed. In addition, the animals underwent fine needle aspiration testicular cytology (FNAC) and two ejaculates from each buck were collected. There were no significant differences between G1 and GC for FNAC and for testicular thermography. On the hemodynamics evaluation the IR was higher for the animals with scrotal bipartition than to control group (0.53a+-0.11 and 0.46b+- 0.06; P=0.0108). In conclusion, goats up to 50% of the scrotum bipartition have the same sperm quality than the control group, and the bipartition was not related to more efficiency on the thermoregulation process or number of testicular primordial cells in this study.(AU)

RESUMO

PURPOSE: To compare the effects of the sleeve gastrectomy with transit bipartition (SG + TB) procedure with standard medical therapy (SMT) in mildly obese patients with type II diabetes (T2D). METHODS: This is a prospective, randomized, controlled trial. Twenty male adults, ≤ 65 years old, with T2D, body mass index (BMI) > 28 kg/m2 and < 35 kg/m2, and HbA1c level > 8% were randomized to SG + TB or to SMT. Outcomes were the remission in the metabolic and cardiovascular risk variables up to 24 months. RESULTS: At 24 months, SG + TB group showed a significant decrease in HbaA1c values (9.3 ± 2.1 versus 5.5 ± 1.1%, P = < 0.05) whereas SMT group maintained similar levels from baseline (8.0 ± 1.5 versus 8.3 ± 1.1%, P = NS). BMI values were lower in the SG + TB group (25.3 ± 2.8 kg/m2 versus 30.9 ± 2.5 kg/m2; P = < 0.001). At 24 months, none patient in SG + TB group needed medications for hyperlipidemia/hypertension. HDL-cholesterol levels increased in the SG + TB group (33 ± 8 to 45 ± 15 mg/dL, P < 0.001). After 24 months, the area under the curve (AUC) of GLP1 increased and in the SG + TB group and the AUC of the GIP concentrations was lower in the SG + TB group than in the SMT. At 3 months, SG + TB group showed a marked increase in FGF19 levels (74.1 ± 45.8 to 237.3 ± 234 pg/mL; P = 0.001). CONCLUSIONS: SG + TB is superior to SMT and was associated with a better metabolic and cardiovascular profile.

RESUMO

With the objective to assess the effect of scrotal bipartition on spermatogenesis in sheep, the testes were used from 12 crossbred rams of sheep farms in the municipality of Patos, Paraíba, Brazil, distributed into two groups: GI with six rams with scrotal bipartition, and GII with six rams without scrotal bipartition. The testicular biometry was measured and the testes were collected, fixed in Bouin and fragments were processed to obtain histological slides. The spermatogenesis yield and the Sertoli cell efficiency was estimated by counting the cells of the spermatogenetic line at stage one of the seminiferous epithelium cycle and the Sertoli cells. The results were submitted to analysis of variance with the ASSISTAT v.7.6 program and the mean values were compared by the Student-Newman-Keuls test (SNK) at 5% significance. The testicular biometric parameters did not show statistical difference (p>0.05) between the groups. The meiotic, spermatogenetic and Sertoli cell efficiency were higher in bipartitioned rams (p<0.05), while the mitotic yield did not differ (p>0.05) between GI and GII. The results indicated that there is superiority in the spermatogenetic parameters of bi-partitioned rams, suggesting that these sheep present, as reported in goats, indication of better reproductive indices.

Com o objetivo de avaliar o efeito da bipartição escrotal sobre a espermatogênese em ovinos, foram utilizados os testículos de 12 ovinos sem raça definida oriundos de criadouros do município de Patos-PB, Brasil, distribuídos em dois grupos, GI de seis animais com bipartição escrotal e o GII de seis animais sem bipartição escrotal. Realizou-se a aferição da biometria testicular, em seguida, os testículos foram coletados, fixados em Bouin e fragmentos foram processados para obtenção de lâminas histológicas. Foi estimado o rendimento da espermatogênese e eficiência das células de Sertoli contando-se as células da linhagem espermatogênica no estádio I do Ciclo do Epitélio Seminífero, bem como as células de Sertoli. Os resultados foram submetidos à análise de variância pelo programa ASSISTAT v.7.6 e os valores médios foram comparados pelo teste Student-Newman-Keuls (SNK) a 5% de significância. Os parâmetros de biometria testicular não apresentaram diferença estatística (p>0,05) entre os grupos. Os rendimentos meiótico, espermatogênico e a eficiência das células de Sertoli mostraram-se superiores em animais bipartidos (p<0,05), enquanto o rendimento mitótico não diferiu (p>0,05) entre GI e GII. Os resultados indicaram existir superioridade nos parâmetros espermatogênicos de ovinos bipartidos, sugerindo que estes animais apresentam, assim como constatado em caprinos, indicativo de melhores índices reprodutivos.

RESUMO

O diabetes mellitus tipo 2 (DM2) é uma doença de prevalência crescente na população mundial, sendo associado ao aumento de diversas comorbidades. A relação entre o trato digestivo e o DM2 tem sido fortalecida a partir dos resultados das diferentes cirurgias metabólicas frente à remissão do distúrbio endócrino. Alterações morfológicas hipertróficas no epitélio intestinal são percebidas nos estágios iniciais da doença e parece ter papel primordial na instalação da hiperglicemia crônica. O gene p53 participa ativamente dos processos de regulação do crescimento epitelial intestinal e pode sofrer alteração de sua expressão em estados diabéticos. Objetiva-se avaliar os resultados clínicos e laboratoriais de pacientes DM2 e com índice de Massa Corpórea (IMC) >25 e <35 Kg/m2 submetidos a cirurgia metabólica denominada adaptação digestiva com duodenal switch parcial (DSP) e avaliar o comportamento da expressão do gene p53 na mucosa intestinal no período pré e pós-operatório. Nove pacientes DM2, com IMC<35Kg/m2 foram operados pela técnica DSP. Biópsias de duodeno e íleo foram colhidas no estado diabético (pré e transoperatório respectivamente) e, 3 meses após a cirurgia, através de endoscopia digestiva alta. Foram comparados os dados de evolução antropométrica (IMC) e laboratorial no período pré e pós-operatório. Através do método enzyme-linked immunosorbent assay (ELISA) foram determinados os níveis dos entero-hormônios glucagon-like peptide-1 (GLP-1) e glucose-dependent insulinotropic peptide (GIP), no pré e pós-operatório, em jejum e pós-prandial nos períodos 30',60',90' e 120'. A expressão do gene p53, foi avaliada por real time polymerase chain reaction (qrt-PCR) e western blot, nos dois diferentes momentos. As variáveis: glicemia de jejum e pós-prandial (2 horas), trigliceridemia de jejum, hemoglobina glicada (HbAc1) e peptídeo C foram analisadas. As médias dos parâmetros laboratoriais foram comparadas pela análise multivariada ANOVA e após teste-Tukey...

Diabetes mellitus type 2 (DM2) is a worldwide increasing prevalence disease, being related to a variety of comorbidities. The relationship between the digestive tract and DM2 has been strengthened by the results of different metabolic surgery procedures on resolution of the endocrine disorder, before weigh loss achievement. Hypertrophic morphological changes in the intestinal epithelium are observed in the early stages of disease development and seems to have a pivotal role in the establishment of chronic hyperglicemia. The p53 gene directly participates on regulation of growth processes of the intestinal epithelium, and its expression has been shown to be altered in diabetic states.The objectives were to evaluate clinical and laboratory results in DM2 patients, presenting Body Mass Index(BMI)>25 and <35Kg/m2, undergoing a metabolic surgery procedure called digestive adaptation with partial duodenal switch(DSP). To assess p53 gene expression behavior in intestinal mucosa, on pre and postoperative period. Nine patients presenting DM2 and BMI below 35Kg/m2 underwent DSP.Biopsies of the duodenum and intermediate portion of the ileum were undertaken in diabetic state (pre and transoperative respectively) and 3 months after surgery by upper gastrointestinal endoscopy. The evolution of anthropometric (BMI) and laboratory parameters were acessed on postoperative period. Serum levels of enterohormones glucagon-like peptide-1(GLP-1) and glucose-dependent insulinotropic peptide (GIP) were determined by the method enzyme-linked immunosorbent assay (ELISA), pre and postoperatively, on fasting and postprandial state (30',60'90 and 120') after ingestion of a standart meal.The p53 gene expression was evaluated by real time polymerase chain reaction (qrt-PCR) and western blot, on two different periods. The variables: fasting and postprandial (2 hours) glicemia, fasting triglycerides (TG), glycosylated hemoglobin (HbA1c) and C-peptide were undertaken...

RESUMO

The scrotal-testicular biometry was evaluated in goats raised in Piaui state, Brazil, presenting different levels of scrotal division, in rainy and dry periods of the year. For this study, eighteen male goats at mating age were accomplished and arranged into three groups (6 animals each), obeying the classification as goats with no scrotal bipartition (GI), goats showing scrotal bipartition up to 50 percent of testicular length (GII), and goats with more than 50 percent of scrotal bipartition (GIII). The biometry of the scrotal-testicular was made evaluating the scrotal length (SL), scrotal circumference (SC), testicular length (TL) and testicular volume (TV). The results were evaluated following the variance analysis (ANOVA) and the SNK test applied on the average comparisons. The analysis of the data demonstrated high values, in dry and rainy periods, of SC (24.63cm/ 26.97cm), SL (16.61cm/ 18.24cm), TL (5.32cm/ 5.93cm), TV (173.81cm³/ 203.01cm³). This supports the hypothesis of the influence of the period of the year and of the scrotal bipartition on the scrotal-testicular biometry in goat.(AU)

Objetivou-se neste trabalho avaliar a biometria escroto-testicular em caprinos com escroto simples e bipartido, criados no Estado do Piauí, Brasil, nos períodos seco e chuvoso do ano. Foram utilizados 18 caprinos machos, divididos em três grupos de seis caprinos. O grupo I (escroto sem bipartição), o grupo II (escroto bipartido até 50 por cento de comprimento testicular) e o grupo III (bipartição escrotal superior a 50 por cento do comprimento testicular). A biometria escroto-testicular consistiu do comprimento escrotal (COE), circunferência escrotal (CE), comprimento testicular (CT) e volume testicular (V). Os resultados foram submetidos à análise de variância (ANOVA), seguido do teste SNK para comparação das médias. Os dados mostraram que os animais do grupo GIII apresentaram, no período seco, os valores de CE, COE, CT e V de 24,63cm, 16,61cm, 5,32cm, e 173,81cm³, respectivamente e de 26,97cm para CE, 18,24cm para COE, 5,93cm para CT e 203,01cm³ para V, no período chuvoso. Todos esses valores foram superiores (p<0,05) aos encontrados para os animais dos demais grupos. Conclui-se que o grau de bipartição escrotal e o período do ano interferem na biometria escroto-testicular de caprinos.(AU)
