Duplicación del colédoco asociado a unión biliopancreática anómala: Reporte de caso / Common bile duct duplication associated with anomalous biliopancreatic junction: A case report

Introducción. La duplicación del colédoco es una anomalía congénita poco frecuente. En la mayoría de los casos este defecto se asocia a cálculos en la vía biliar, unión pancreatobiliar anómala, pancreatitis, cáncer gástrico o colangiocarcinoma. Por esta razón, el diagnóstico y el tratamiento temprano son importantes para evitar las complicaciones descritas a futuro. Métodos. Se presenta el caso de una paciente de 30 años, con antecedente de pancreatitis aguda, con cuadro de dolor abdominal crónico, a quien se le realizaron varios estudios imagenológicos sin claro diagnóstico. Fue llevada a manejo quirúrgico en donde se documentó duplicación del colédoco tipo II con unión pancreatobiliar anómala. Resultados. Se hizo reconstrucción de las vías biliares y hepatico-yeyunostomía, con adecuada evolución postoperatoria y reporte final de patología sin evidencia de tumor. Conclusión. El diagnóstico se hace mediante ecografía endoscópica biliopancreática, colangiorresonancia o colangiopancreatografía retrógrada endoscópica. El tratamiento depende de si está asociado o no a la presencia de unión biliopancreática anómala o cáncer. Si el paciente no presenta patología neoplásica, el tratamiento quirúrgico recomendado es la resección del conducto con reconstrucción de las vías biliares.

Introduction. Double common bile duct is an extremely rare congenital anomaly. This anomaly may be associated with bile duct stones, anomalous biliopancreatic junction, pancreatitis, bile duct cancer, or gastric cancers. Thus, early diagnosis and treatment is important to avoid complications. Clinical case. We report a rare case of double common bile duct associated with an anomalous biliopancreatic junction in a 30-year-old female, with prior history of acute pancreatitis, who presented with chronic abdominal pain. She underwent several imaging studies, without clear diagnosis. She was taken to surgical management where duplication of the type II common bile duct was documented with anomalous pancreatobiliary junction. Results. Reconstruction of the bile ducts and hepatico-jejunostomy were performed, with adequate postoperative evolution and final pathology report without evidence of tumor. Conclusion. Diagnosis is usually performed by an endoscopic ultrasound, magnetic resonance cholangiopancrea-tography, or endoscopic retrograde cholangiopancreatography. Treatment depends on the presence of anomalus biliopancreatic junction or concomitant cancer. In cases without associated malignancy, resection of bile duct and biliary reconstruction is the recommended surgical treatment.

Myricetin attenuates renal fibrosis by activating Nrf2/HO-1 pathway to inhibit oxidative stress / 药学学报

This paper investigates the effect of myricetin (MYR) on renal fibrosis induced by unilateral ureteral obstruction (UUO) and common bile duct ligation (CBDL) in mice and its mechanism. The animal experiment has been approved by the Ethics Committee of China Pharmaceutical University (NO: 2022-10-020). Thirty-five ICR mice were divided into control, UUO, UUO+MYR, CBDL and CBDL+MYR groups. H&E and Masson staining were used to detect pathological changes in kidney tissues. Western blot (WB) was used to detect the expression of fibrosis-related proteins in renal tissue, and total superoxide dismutase (SOD) activity detection kit (WST-8) was used to detect the changes of total SOD in renal tissue of CBDL mice. In vitro, HK-2 cells and transforming growth factor beta 1 (TGF-β1, 10 ng·mL-1) were used to induce fibrotic model, and high glucose (30 mmol·L-1) was used to induce oxidative stress model, and then treated with different concentrations of MYR, WB was used to detect the expression of fibrosis and oxidative stress-related proteins, while NIH/3T3 cells were treated with different concentrations of MYR, and their effects on cell proliferation were detected by 5-bromo-2′-deoxyuridine (Brdu). The results showed that the renal lesions in UUO group and CBDL group were severe, collagen deposition was obvious, the expression of collagen-Ⅰ (COL-Ⅰ), α-smooth muscle actin (α-SMA), fibronectin (FN), vimentin and plasminogen activator inhibitor-1 (PAI-1) protein was up-regulated, and the activity of SOD enzyme in CBDL group was significantly decreased. MYR partly reversed the above changes after treatment. MYR inhibited the proliferation of NIH/3T3 cells but had no effect on the proliferation of HK-2 cells, and decreased the upregulation of PAI-1, FN and vimentin in HK-2 cells stimulated by TGF-β1. MYR can also up-regulate the down-regulation of nuclear factor erythroid 2-related factor 2 (Nrf2) and heme oxygenase-1 (HO-1) in HK-2 cells stimulated by high glucose. To sum up, MYR can improve renal fibrosis in vivo and in vitro, probably by inhibiting the proliferation of fibroblasts and activating Nrf2/HO-1 signal pathway to inhibit oxidative stress.

Ethical Dilemma in Global Vaccine Cooperation and Its Countermeasures: Taking the Global Eradication of Smallpox as an Example / 中国医学伦理学

Vaccine cooperation is an important means to deal with global infectious diseases. However, the cooperation cannot be achieved overnight. Ethical dilemma is one of the obstacles that hinders vaccine cooperation. Reviewing the history, the most successful vaccine collaboration to date has been the global smallpox eradication program. In the process of eradicating smallpox, there were also many ethical dilemmas, including the international pattern of the US-Soviet hegemony, which impacted the mutual help between countries, the ethical disputes of the vaccine itself hindering solidarity and cooperation among actors, and the vaccine coercion adopted to overcome vaccine hesitancy undermining the principle of proportionality among the freedom, equality and efficacy. The ethical dilemmas of vaccine cooperation were resolved by shaping professional and scientific consensus among medical professional groups, reaching consensus on cooperation between leading countries and developing countries, and integrating local culture to improve vaccination methods. Finally, in 1980, the world successfully eradicated smallpox. The case of smallpox eradication provides us lessons for vaccine cooperation against COVID-19 and the construction of a community of common health for mankind today.

Research progress on dental materials for preventing root caries / 口腔疾病防治

@#The high incidence and untreated rate of root caries, a common and frequently occurring oral disease with challenging treatment in elderly individuals, is the main cause of tooth loss among elderly people, as rapid development results in pulpitis and periapical periodontitis or residual crown and root, which has been regarded as one of the common chronic oral diseases seriously affecting the quality of life of elderly people. Thus, early intervention and prevention are important. Traditional dental materials for preventing root caries have been widely used in clinical practice; however, they have the disadvantages of tooth coloring, remineralization and low sterilization efficiency. A series of new dental materials for preventing root caries have gradually become a research hotspot recently, which have the advantages of promoting the mineralization of deep dental tissue, prolonging the action time and enhancing adhesion. Future caries prevention materials should be designed according to the characteristics of root surface caries and the application population and should be developed toward simplicity, high efficiency and low toxicity. This review describes current research regarding anti-caries prevention material application, serving as a theoretical underpinning for the research of root caries prevention materials, which is important for both promotion in the effective prevention of root caries and improvement in the status of oral health and the quality of life among old people.

Ethics in infectious diseases: latent challenges. Part I / Ética en enfermedades infecciosas: retos latentes. Parte I

Abstract Infectious diseases socially imply individual and community medical problems. Therefore, they require actions aimed at social processes that affect the well-being of the individuals without losing sight of social groups. Faced with this panorama, we ask ourselves: is there a direct relationship between ethics and infectious diseases? To elucidate an answer, let us remember the peak period of the COVID-19 pandemic when guidelines based on ethical principles were issued to facilitate medical decisions on allocating scarce resources in periods of maximum demand. In those moments, since there was no inclusive component of society, the decisions made produced massive criticism. The reactions demonstrated the need to analyze in detail the criteria that had been considered correct. Consequently, we affirm that bioethical principles are transcendental in medical decisions and must be examined, not only for the individual but also with a view to public health. Moreover, the acquired immunodeficiency syndrome (AIDS) epidemic has lived with us for decades, and it continues to show its tragic face in the form of new cases, chronic illnesses, and deaths. Joint United Nations Programme on HIV/AIDS brings us closer to a complex reality where the fight against disease and global health are interrelated with other problems, such as the need to reduce inequality, for which human rights, gender equality, social protection, and the development of research projects, where the ethics committees in research in community processes are constituents.

Resumen Las enfermedades infecciosas implican problemas médicos individuales y comunitarios, por lo que requieren acciones dirigidas a procesos sociales que incidan en el bienestar de los individuos, sin perder de vista a los grupos sociales. Nos preguntamos: ¿existe relación directa entre la ética y las enfermedades infecciosas? Para dilucidar una respuesta, recordemos el periodo más álgido de la pandemia por COVID-19, cuando se emitieron guías fundamentadas en principios éticos para facilitar las decisiones médicas en la asignación de recursos escasos en periodos de máxima demanda. Al no haber un componente inclusivo con la sociedad, las decisiones que se tomaron produjeron críticas masivas, que demostraron la necesidad de analizar a detalle los criterios que se habían considerado correctos. En consecuencia, afirmamos que los principios bioéticos son trascendentales en las decisiones médicas y deben ser examinados, no solo frente al individuo, sino de cara a la salud pública (bien común e individualidad). Por otra parte, la epidemia del SIDA (síndrome de inmunodeficiencia adquirida) convive con nosotros desde hace décadas. ONUSIDA (Programa Conjunto de las Naciones Unidas sobre el VIH/SIDA) nos acerca una realidad compleja, como es que la lucha contra la enfermedad y por la salud global se interrelaciona con otros problemas como la necesidad de reducer la desigualdad, por los derechos humanos, la igualdad de género, la protección social y el desarrollo de proyectos de investigación, donde los comités de Ética en investigación en procesos comunitarios son constituyentes.

The Regulatory Status of Functional Foods in the Economic Integration Organizations of Latin America and the Caribbean / El Estatus Regulatorio de los Alimentos Funcionales en las Organizaciones de Integración Económica de Latinoamérica y el Caribe

Introduction. The legal declarations on functional foods of the four main economic integration organizations in Latin America and the Caribbean (LAC) ­ Pacific Alliance (PA), Caribbean Community (CARICOM), Southern Common Market (MERCOSUR) and Central American Integration System (SICA) - are based on the Codex Alimentarius system and do not regulate functional foods. The use of Codex in food marketing is an insufficient condition for its application in functional foods. Regulation based on scientific and technology results are required to be used in the economic integration organizations of LAC. Objective. The objective is to analyze the theoretical framework of the legal foundations that could govern the commercialization processes of functional foods, whose research advances have currently only been manifested in nutritional health. This article also seeks to address this gap through a systematic analysis of international regulations. Materials and methods. For this, a review of the literature emanating from two databases from 2018-2023 is carried by applying the legal-economic research method of documentary content analysis, applied to three general food marketing regulations: food safety declarations, regulations for inspections, food manufacturing and food labeling. Results. The results reveal the absence of specific legislation for functional foods in LAC economic integration organizations. Conclusions. The legal principle of marketing based on peremptory norm (also called jus cogens) can be facilitated through side letters, included in the contents of international contracts. along with the registration requirements of industrial property rights of the member countries associations(AU)

Introducción. Las declaraciones legales sobre alimentos funcionales de las cuatro principales organizaciones de integración económica de América Latina y el Caribe (ALC) ­ Alianza del Pacífico (AP), Comunidad del Caribe (CARICOM), Mercado Común del Sur (MERCOSUR) y Sistema de Integración Centroamericana (SICA) - se basan en el sistema del Codex Alimentarius y no regulan los alimentos funcionales. El uso del Codex en la comercialización de alimentos es condición insuficiente para su aplicación en alimentos funcionales. Se requiere que las regulaciones basadas en resultados científicos y tecnológicos sean utilizadas en los organismos de integración económica de ALC. Objetivo. Analizar el marco teórico de los fundamentos legales que podrían regir los procesos de comercialización de alimentos funcionales, cuyos avances en investigación actualmente solo se han manifestado en salud nutricional. Este artículo también busca abordar esta brecha a través de un análisis sistemático de las regulaciones internacionales. Materiales y métodos. Se realiza una revisión de la literatura emanada de dos bases de datos del período 2018-2023 aplicando el método de investigación jurídico- económica de análisis de contenido documental, aplicado a tres normas generales de comercialización de alimentos: declaraciones de seguridad alimentaria, normas para inspecciones, fabricación de alimentos y etiquetado de alimentos. Resultados. Los resultados revelan la ausencia de legislación específica para alimentos funcionales en las asociaciones comerciales de ALC. Conclusiones. El principio jurídico de comercialización basado en norma imperativa (también llamado jus cogens) puede facilitarse a través de cartas complementarias, incluidas en el contenido de los contratos internacionales. junto con los requisitos de registro de los derechos de propiedad industrial de las asociaciones de los países miembros(AU)

High frequency of larval abnormalities of the toad Rhinella arenarum (Anura: Bufonidae) in an Argentinian agroecosystem

Introduction: The frequent use of pesticides is currently considered a cause of environmental pollution due to the high rate of entry of these substances into agroecosystems. This constitutes a risk for the species that inhabit these ecosystems, in particular anurans whose characteristics make them prone to exposure to and interaction with environmental pollutants. Objective: To report the occurrence of abnormalities in larvae of the common toad Rhinella arenarum inhabiting ponds surrounded by agroecosystems. Methods: In two consecutive springs (2015 and 2016), reproductive events of common toads were monitored in temporary pond systems in agricultural and non-agricultural areas, located near the city of La Plata (Buenos Aires, Argentina). The physicochemical parameters of the ponds were measured, and the stage of each reproductive event was recorded, such as the numbers of adult toads, amplexus and clutches. In the laboratory, the larvae were measured and photographed, their stage of development was recorded, and their morphology was examined under a stereomicroscope. Representative samples (normal and abnormal) from each pond studied were processed for histopathological analysis. Results: In the field studies carried out on a population of R. arenarum collected in an agroecosystem, a lower number of reproductive adults and clutches were observed in relation to the population of a non-agricultural pond. A total of 1 910 larvae were collected: 529 and 1 381 larvae from ponds located in non-agricultural and agricultural areas, respectively. Larvae from the agroecosystem showed two types of abnormalities: severe tail flexure and abdominal bloating. In addition, five degrees of severity could be determined in relation to abdominal bloating. Conclusions: This work reports the high frequency and severity of abnormalities observed in the early stages of R. arenarum larvae living within an agroecosystem, providing evidence of the negative impact that agricultural activities cause on aquatic ecosystems surrounded by farming areas.

Introducción: El uso frecuente de plaguicidas es considerado actualmente una causa de contaminación ambiental debido a las altas tasas de ingreso de estas sustancias a los agroecosistemas. Esta situación es un riesgo para las especies que habitan en estos ecosistemas, en particular los anuros cuyas características los hacen propensos a la exposición e interacción con contaminantes ambientales. Objetivo: Informar la presencia de anormalidades en larvas del sapo común Rhinella arenarum que habitan en estanques rodeados por un agroecosistema. Métodos: En dos primaveras consecutivas (2015 y 2016), se monitorearon los eventos reproductivos del sapo común proveniente de sistemas de estanques temporales ubicados en zonas agrícolas y no agrícolas, cerca de la ciudad de La Plata (Buenos Aires, Argentina). Se midieron los parámetros fisicoquímicos de los estanques y se registraron las etapas de cada evento reproductivo como el número de sapos adultos, amplexos y nidadas. En el laboratorio, las larvas fueron medidas y fotografiadas, se registró su estado de desarrollo y se examinó la morfología de cada una bajo microscopio estereoscópico. Se procesaron muestras representativas (normales y anormales) de cada estanque estudiado para análisis histopatológico. Resultados: En la población de R. arenarum que vive dentro de un agroecosistema, se observó un menor número de adultos reproductores y puestas en relación con la del estanque en la zona no agrícola. Se recolectaron un total de 1 910 larvas: 529 y 1 381 larvas de estanques ubicados en zonas no agrícolas y agrícolas, respectivamente. Las larvas del agroecosistema mostraron dos tipos de anormalidades: severa flexión de la cola y distensión abdominal. Además, se pudo determinar cinco grados de gravedad en relación con la distensión abdominal. Conclusiones: Una alta frecuencia y severidad de anormalidades en los estadios tempranos de larvas de R. arenarum que viven dentro de un agroecosistema proporciona evidencia del impacto negativo que las actividades agrícolas causan en los ecosistemas acuáticos rodeados por áreas de cultivo.

Transtornos Mentais Comuns em quilombolas rurais do Norte de Minas Gerais, Brasil / Common Mental Disorders in rural "quilombolas" in the North of Minas Gerais, Brazil

Resumo O objetivo deste artigo é avaliar a prevalência e fatores associados aos Transtornos Mentais Comuns (TMC) em quilombolas residentes em comunidades rurais localizadas no norte de Minas Gerais, Brasil. Trata-se de estudo transversal realizado em 2019 a partir de entrevistas estruturadas e aplicação do Self Reporting Questionnaire (SRQ-20). Foi conduzida regressão logística binária. A prevalência de TMC foi de 38,7%. Houve maior chance de TMC entre quilombolas do sexo feminino (OR: 2,69; IC95% 2,00-3,62), com 1 a 8 anos de estudo (OR: 1,70; IC95% 1,15-2,51), renda familiar entre 1 a 1,5 salário mínimo (OR: 2,51; IC95% 1,60-3,94); que sofreram discriminação em serviços de saúde (OR: 2,44; IC95% 1,44-4,13); com autorrelato de doença pulmonar (OR: 2,10; IC95% 1,25-3,54), doença cardíaca (OR: 1,58; IC95% 1,01-2,50) e insuficiência renal crônica (OR: 1,97; IC95% 1,08-3,94), e com autopercepção de saúde negativa (OR: 3,07; IC95% 2,31-4,07). A alta prevalência de TMC observada neste estudo demonstra a necessidade de políticas de atenção à saúde mental voltadas para as populações vulnerabilizadas, como as comunidades quilombolas, a fim de mitigar o sofrimento mental e favorecer uma atenção profissional contextualizada com as singularidades das condições de vida e saúde desse grupo populacional.

Abstract The scope of this article is to assess the prevalence and factors associated with Common Mental Disorders (CMD) in "quilombolas" (Afro-Brazilian residents of quilombo settlements) in rural communities located in the North of Minas Gerais, Brazil. It is a cross-sectional study of 2019 based on structured interviews and application of a Self-Reporting Questionnaire (SRQ-20). Binary logistic regression was conducted. The prevalence of CMD was 38.7%. There was a higher preponderance of CMD among female quilombolas (OR: 2.69; 95%CI 2.00-3.62), with 1 to 8 years of schooling (OR: 1.70; 95%CI 1.15-2,51), family income of 1 to 1,5 minimum wages (OR: 2.51; 95%CI 1.60-3.94); who suffered discrimination in health services (OR: 2.44; 95%CI 1.44-4.13); with self-reported lung disease (OR: 2.10; 95%CI 1.25-3.54), heart disease (OR: 1.58; 95%CI 1.01-2.50) chronic renal failure (OR: 1.97; 95%CI 1.08-3.94), and negative self-perception of health (OR: 3.07; 95%CI 2.31-4.07). The high prevalence of CMD revealed in this study demonstrates the need for mental health care policies aimed at vulnerable populations, such as quilombola communities, in order to mitigate mental suffering and promote professional contextualized care for the idiosyncrasies of health and living conditions of this population group.

Accessory right hepatic artery and its significance for a surgeon: A case report

Right hepatic artery (RHA) is a branch of the common hepatic artery; however, there are cases documented in the literature showing anatomical variations. Accessory RHA is an incidental finding during hepatobiliary and pancreatic surgery. This artery should be identified, carefully separated, and preserved during these surgeries. We encounter the variation while doing Whipple’s procedure in a 61-year-old patient diagnosed with carcinoma of the head of the pancreas. Intra-operatively, accessory RHA was present which was arising from the superior mesenteric artery. It was identified, carefully separated, and preserved. Variations in the origin of the artery may make it vulnerable to injuries during surgical procedures if due care is not taken

We need to work together and design a rational, scientific and socially sustainable Heart Smart diabetes care ecosystem, with Heart Smart management strategies, to ensure happiness and harmony in persons who live with diabetes.

Transtornos mentais comuns entre gays: evidenciando vulnerabilidades na pandemia da Covid-19 / Common mental disorders among gay men: showing vulnerabilities in the covid-19 pandemic / Trastornos mentales comunes entre los homosexuales: evidencia de vulnerabilidades en la pandemia de

Objetivou-se investigar a incidência de Transtornos Mentais Comuns (TMC) entre gays e no intragrupo que se autoidentificam como afeminados, durante o período pandêmico. Para tanto, utilizou-se de forma remota o Self-Reporting Questionnaire (SRQ-20) junto a 43 participantes cisgêneros, bem como fez-se entrevistas junto a 08 gays que se autoidentificam como afeminados. Encontrou-se indicativo de TMC em 60,5% dos participantes. Há uma heterogeneidade nos modos de sofrimento mental entre homens gays durante a pandemia, uma vez que marcadores sociais como raça, renda, escolaridade, local de moradia e ser gay afeminado foram determinantes para o adoecimento mental. O confinamento social durante a pandemia ampliou as vulnerabilidades, seja pela intensificação do contato com a família de origem ­ tradicionalmente conservadora e heteronormativa ­ seja pelo afastamento dos espaços da cidade e dos laços comunitários e de acolhimento LGBTQ+. A incidência de TMC foi elevada dentre os participantes, em especial, no intragrupo dos gays afeminados (87,5%), evidenciando vulnerabilidades na pandemia da Covid-19. (AU)

The objective was to investigate the incidence of Common Mental Disorders (CMD) among gays and in the intragroup that self-identify aseffeminate gays,during the pandemic period. For this purpose, the Self-Reporting Questionnaire (SRQ-20) was used remotely with 43 cisgender participants, as well as interviews with 08 gays who recognized themselves as effeminate. Indicative of CMD was found in 60.5% of the participants. There is a heterogeneity in the modes of mental suffering among gay men during the pandemic,since social markers such as race, income, education, place of residence and being an effeminate gay were decisivefor mental illness. Social confinement during the pandemic increased vulnerabilities, either by intensifying contact with the family of origin -traditionally conservative and heteronormative -or by distancing from city spaces and LGBTQ + community and host ties. The incidence of CMD was high among the participants, especially in the intragroup of effeminate gays(87,5%), showing vulnerabilities in the Covid-19 pandemic. (AU)

Myasthenia gravis in the complex scenario of LRBA-related immune dysregulation / Miastenia gravis no cenário clínico complexo das imunodesregulações relacionadas ao gene LRBA

Autoimmune diseases have been progressively recognized as a potential complication of primary immunodeficiency, especially for some genetic subtypes of common variable immunodeficiency. Although often associated with other autoimmune disorders, autoimmune myasthenia gravis is occasionally identified as a neuromuscular complication of primary immunodeficiency. We report the case of a Brazilian woman with common variable immunodeficiency-8 due to an LRBA variant, in which myasthenia gravis was identified in association with anti-acetylcholine receptor antibody. Marked clinical improvement occurred after intravenous immunoglobulin therapy.

Doenças autoimunes foram progressivamente reconhecidas como complicações potenciais das imunodeficiências primárias, especialmente para alguns subtipos genéticos das imunodeficiências comuns variáveis. Embora se associe comumente a outras doenças autoimunes, a Miastenia gravis autoimune adquirida foi raramente associada como complicação neuromuscular de imunodeficiências primárias. É descrito neste artigo o caso de paciente brasileira do sexo feminino com diagnóstico de Imunodeficiência Comum Variável tipo 8 por variante no gene LRBA, na qual foi identificada Miastenia gravis em associação a anticorpos antirreceptor de acetilcolina. Ela evoluiu com marcante melhora clínica após a introdução de terapêutica com imunoglobulina endovenosa.

Morinda citrifolia L. (Noni) dietary supplementation ameliorates fluoride toxicity in the freshwater fish, Cyprinus carpio L

Fluoride is the organic and inorganic compound of the element fluorine, has detrimental effect to all animals including fish at higher concentration. Ground water with elevated concentration of fluoride is a major global problem including India. On the other hand, Morinda citrifolia (also called ‘Noni’ in Polynesia) is a medicinal plant, has antioxidative, anti-inflammatory and immunostimulatory properties. The ameliorating effect of M. citrifolia fruit extract dietary supplementation against fluoride induced toxicity on the growth performance, haematological parameters, and fluoride accumulation in the muscular tissue was investigated in the freshwater fish, Cyprinus carpio L. for 35 days in triplicate. One hundred and twenty acclimated C. carpio fingerlings were randomly allocated into five experimental groups (Groups I, II, III, IV and V) each with 24 fish divided into three replicates (eight fish/replicate). Group I (Control) and II (Toxic control or negative control) were provided with basal/control diet, whereas groups III, IV, and V were provided with 0.25% (2.5 g/kg), 0.50% (5.0 g/kg) and 0.75% (7.5 g/kg) M. citrifolia fruit extract supplemented diet respectively. All groups except for group I were exposed to 10% of the LC50 of fluoride. Selected growth and haematological parameters were estimated. The fluoride content in the muscular tissue of fish was also estimated following SPADNS method. Results revealed that exposure of sublethal concentration of fluoride significantly (P <0.05) reduced the growth performance and haematological parameters in Gr. II (toxic control) compared to the Gr. I (control). However, M. citrifolia dietary supplementation significantly (P <0.05) improved fluoride induced alteration of growth performance and haematological parameters of fish in the groups III, IV and V compared to Gr. II. Morinda citrifolia fruit extract dietary supplementation also significantly (P <0.05) decreased the accumulation fluoride in the muscular tissue of fish in groups III, IV and V compared to the Gr. II (toxic control). In conclusion, M. citrifolia dietary supplementation ameliorates the fluoride toxicity by preventing the accumulation of fluoride in the muscular tissue of the fish. The M. citrifolia dietary supplementation at 0.25% showed the best response, hence it is considered as the optimum dose.

Presiones de la vía biliar en pacientes con y sin colelitiasis

Introducción: El reflujo de enzimas pancreáticas hacia la vía biliar extra-hepática y la vesícula biliar es un fenómeno anormal que tiene un rol en la litogénesis y carcinogénesis. Debido a que la presión de la vía biliar depende entre otros factores, de las presiones del esfínter de Oddi. La disfunción de éste se vería reflejada en presiones elevadas de la vía biliar en pacientes con colelitiasis. Objetivo: El objetivo de este estudio es el de medir las presiones de la vía biliar extra-hepática en pacientes con y sin colelitiasis y relacionarlas con la presencia de reflujo pancreáticobiliar. Material y Método: Se diseñó un estudio pros-pectivo de casos y controles. La muestra está constituida por todos los pacientes operados con gastrectomía total por cáncer gástrico estadios I y II durante 30 meses. La medida de resultado primaria fue establecer diferencias en las presiones de la vía biliar entre pacientes con y sin colelitiasis. Resultados: Las presiones de la vía biliar extra-hepática en pacientes con colelitiasis fueron más elevadas (16,9 mmHg) que en los pacientes sin colelitiasis (3,3 mmHg) (p < 0,0001). Estas presiones se correlacionan con la presencia de amilasa y lipasa en la bilis de la vesícula; se encontraron niveles elevados de enzimas pancreáticas en pacientes con colelitiasis (p < 0,0001). Conclusiones: Las presiones de la vía biliar en pacientes con colelitiasis fueron, significativamente, mayores comparadas con las presiones de la vía biliar en pacientes sin colelitiasis. En los pacientes con colelitiasis, la presión elevada de la vía biliar se asocia a la presencia de reflujo pancreáticobiliar.

Background: The reflux of pancreatic enzymes into the bile duct and the gallbladder is an abnormal phenomenon that plays a role in lithogenesis and carcinogenesis. Because the pressure of the common bile duct depends on the pressures of the sphincter of Oddi, its dysfunction would be reflected in an increase in the pressure of the common bile duct in patients with cholelithiasis. Aim: The objective of this study was to measure the pressures of the common bile duct in patients with and without cholelithiasis and to relate them to the presence of pancreatobiliary reflux. Material and Method: A prospective case-control study was designed. The universe was constituted by all patients undergoing total gastrectomy for gastric cancer stages I and II during 30 months. The primary outcome measure was to establish differences between common bile duct pressures in patients with and without cholelithiasis. Results: Common bile duct pressures in patients with gallstones showed a significant elevation (16.9 mmHg) compared to patients without gallstones (3.3 mm Hg) (p < 0.0001). These pressures correlated with the levels of amylase and lipase in gallbladder bile; higher levels were found in patients with gallstones compared to patients without gallstones (p < 0.0001). Conclusions: Common bile duct pressure in patients with cholelithiasis was significantly higher compared to patients without cholelithiasis leading to pancreatobiliary reflux.

Harvester’s palsy – bilateral common peroneal nerve palsy: A descriptive case report

Peroneal neuropathy is the common mononeuropathy of the lower extremities in adults. The documented etiologies for peroneal nerve injury include trauma, traction, and external compression. Fibular neck is the most common site of common peroneal nerve (CPN) injury as the nerve lies superficial and vulnerable for injury. A 50-year-old male presented with foot drop in his left leg after working in squatting position for prolonged hours along with sensory disturbance in dorsum of left foot. Clinical examination showed poor dorsiflexion in both side ankle with preserved plantar flexion. Electrophysiological findings locate the site of lesion to be CPN at the level of fibular neck. We conclude that CPN is injured due to knee flexion in farmers repeatedly squatting for long hours. Superficial peroneal nerve may be spared due to their interfascicular arrangement at the level of fibular neck placing deep peroneal nerve near the fibula making them more susceptible to compression type of injury. Peroneal nerve may be damaged at multiple sites including ankle. The condition can be reversed with conservative treatment, primarily by avoiding the precipitating position.

Transtorno mental comum em populações assistidas pela Atenção Primária à Saúde no Brasil: uma revisão integrativa / Common mental disorders among populations assisted by Primary Health Care in Brazil: an integrative review

Resumo Introdução Na Atenção Primária à Saúde são comuns os relatos de pacientes que apresentam queixas difusas, que indicam sofrimento psíquico, mas estes frequentemente não encontram o tratamento adequado pela dificuldade por parte dos agentes de saúde em reconhecerem e lidarem com as dimensões de sofrimento que não estão classificadas na nosografia psiquiátrica. Objetivo O objetivo do presente estudo foi realizar uma revisão integrativa sobre transtorno mental comum em populações inscritas e acompanhadas por serviços da Atenção Primária à Saúde no Brasil. Método Revisão Integrativa a partir de buscas de artigos publicados nas bases de dados BVS, Scielo, PubMed/Medline e Scopus, entre os anos de 1997 e 2018. Resultados As publicações revisadas apresentaram prevalências de transtorno mental comum que variaram de 20,5% a 64% em populações inscritas e acompanhadas por serviços da Atenção Primária à Saúde. Todos os estudos evidenciaram a associação de transtorno mental comum às situações de vulnerabilidades psicossociais. Os principais fatores associados foram: ser mulher, possuir baixa renda e ter menor nível educacional. Conclusão Os estudos analisados apontam para a importância de investimento em políticas públicas com vistas a diminuir as desigualdades sociais, além de destacarem a necessidade do investimento em estratégias de prevenção e cuidados de TMC.

Abstract Backround Patients attending Primary Health Care in Brazil frequently report diffuse complaints indicating mental suffering. However, it's common that they do not find adequate treatment due to the difficulty of health agents recognizing and dealing with the dimensions of suffering that are not classified in psychiatric nosography. Objective The objective of the present study was to make an integrative review of Common Mental Disorders in populations registered and monitored by Primary Health Care services in Brazil. Method Search of articles published in the BVS, Scielo, PubMed/Medline and Scopus databases from 1997 to 2018. Results The reviewed publications showed a prevalence of Common Mental Disorders ranging from 20.5% to 64% in populations attending primary health care services. All the studies showed an association between the Common Mental Disorders and situations of psychosocial vulnerability. The main associated factors were: being a woman, having a low income, and having a lower level of education. Conclusion The studies point out the importance of investing in public policies to reduce social inequalities. Furthermore, they emphasize the importance of investing in strategies for the prevention and care of Common Mental Disorders among populations attending primary health care in Brazil.

Doble colédoco, variante anatómica infrecuente de la vía biliar. Presentación de caso / Double common bile duct, a rare anatomical variant of the bile tract. Case report

Introducción: la presencia de un conducto colédoco doble es una variante anatómica infrecuente con menos de 200 casos publicados en la literatura hasta la fecha, siendo fundamental los estudios preoperatorios que se le deben realizar a los pacientes, a fin de tener la sospecha o el diagnóstico confirmado, no sólo de la variante anatómica, sino de la patología asociada, siendo estas la coledocolitiasis y las patologías malignas del árbol biliar las más frecuentes, aunque gran parte de los casos son hallazgos incidentales e intraoperatorios.Caso clínico : se presenta el caso de masculino de 81 años de edad, con antecedente de colecistectomía 20 años previos, con diagnóstico de síndrome ictérico obstructivo, y estudios de colangiorresonancia y CPRE que reportan coledocolitiasis. Se decide llevar a acto quirúrgico y se diagnóstica la presencia de conducto colédoco doble como hallazgo. Se realiza derivación biliodigestiva de tipo hepaticoyeyunoanastomosis más ligadura de conducto colédoco accesorio con evolución satisfactoria, con alta médica a los 5 días posteriores, y resultado de biopsia negativo para malignidad.Conclusión : el doble colédoco debe ser adecuadamente diagnosticado y estudiado, así no se confirme el diagnóstico preoperatorio los pacientes deben acudir con estos estudios realizados al acto quirúrgico, ya que, dicho tratamiento dependerá fundamentalmente de la patología asociada(AU)

Introduction: the presence of a double common bile duct is an infrequent anatomical variant with less than 200 cases published in the literature to the date, and preoperative studies that must be performed on patients are essential in order to have the suspicion or diagnosis confirmed, not only of the anatomical variant, but also of the associated pathology, these being choledocholithiasis and malignant pathologies of the biliary tract the most frequent, although most of the cases are incidental and intraoperative findings.Clinical case : the case of an 81-year-old male is presented, with a history of cholecystectomy 20 years prior, with a diagnosis of obstructive icteric syndrome, and magnetic resonance cholangiography and ERCP studies that reported choledocholithiasis. It was decided to carry out surgery and the presence of double common bile duct was diagnosed as a finding. Biliodigestive derivation hepaticojejunoanastomosis type and accessory common bile duct ligation was performed with satisfactory evolution, with medical discharge 5 days later, and biopsy result negative for malignancy.Conclusion : the double common bile duct should be properly diagnosed and studied, even if the preoperative diagnosis is not confirmed, patients should attend the surgical procedure with these studies, since said treatment will depend fundamentally on the associated pathology(AU)

Resección laparoscópica de dilatación quística congénita del conducto cístico en un paciente pediátrico / Laparoscopic Resection of Congenital Cystic Dilatation of the Cystic Duct in a Pediatric Patient

Introducción: La dilatación quística congénita del conducto cístico o dilatación tipo VI de la clasificación de Todani, es una variante rara de dilatación congénita de la vía biliar. Objetivo: Explicar la metodología diagnóstica y terapéutica empleada en un caso pediátrico con esta entidad, y destacar la ventaja de su tratamiento oportuno por vía mínimamente invasiva. Presentación del caso: Paciente masculino de 6 años con sintomatología sugestiva de enfermedad vesicular, referido desde la atención secundaria por sospecha de quiste de colédoco. En el ultrasonido se detectaba una lesión ecolúcida adyacente a la vesícula biliar, sin dilatación de las vías biliares intrahepáticas. Se realizó colangiografía laparoscópica y se confirmó una dilatación quística aislada del conducto cístico, la cual se resecó por vía laparoscópica, igualmente. Conclusiones: La incidencia de la dilatación quística del conducto cístico es muy baja y se puede presentar en niños con sintomatología variable. El diagnóstico generalmente es tardío, puede sospecharse mediante la ecografía abdominal y confirmarse con la colangiografía laparoscópica, aun en ausencia de otros medios diagnósticos más modernos. Su reconocimiento y correcta clasificación permiten realizar el tratamiento quirúrgico definitivo exitosamente, de preferencia por vía laparoscópica(AU)

Introduction: Congenital cystic duct dilatation, or Todani classification type VI dilatation, is a rare variant of congenital bile duct dilatation. Objective: To explain the diagnostic and therapeutic methodology used in a pediatric case with this entity, and to highlight the advantage of its timely minimally invasive treatment. Case presentation: Six-year-old male patient with symptoms suggestive of gallbladder disease, referred from secondary care for suspicion of a common bile duct cyst. Ultrasound showed an echolucent lesion adjacent to the gallbladder, without dilatation of the intrahepatic bile ducts. Laparoscopic cholangiography was performed and confirmed an isolated cystic dilatation of the cystic duct, which was resected laparoscopically, likewise. Conclusions: The incidence of cystic dilatation of the cystic duct is very low and may present in children with variable symptomatology. Diagnosis is usually late, can be suspected by abdominal ultrasound and confirmed by laparoscopic cholangiography, even in the absence of other more modern diagnostic tools. Its recognition and correct classification permit a successful definitive surgical treatment, preferably laparoscopically(AU)
