Treatment of Osteoporosis via Regulation of Endocrine System by Traditional Chinese Medicine： A Review / 中国实验方剂学杂志

In recent years， with the changes of population structure and the aggravation of aging， the prevalence of osteoporosis is increasing year by year. Osteoporosis poses great impacts on the body and family life of the patients and increases the burden on the society. Therefore， the research on osteoporosis is urgent and significant. The imbalance between osteoblasts， osteocytes， and osteoclasts causes abnormal bone metabolism， which destroys the fine structure of bone and increases bone fragility， thus increasing the risk of fracture. Although the pathogenesis of osteoporosis is complex， researchers have confirmed that the imbalance of the endocrine system directly or indirectly promotes the occurrence and development of osteoporosis. Traditional Chinese medicine （TCM） is a treasure of Chinese traditional culture and plays a key role in safeguarding the public health. With unique therapeutic effects and advantages， TCM has been widely accepted. Chinese medicines， moxibustion， acupuncture and other TCM therapies have play a unique role in the treatment of osteoporosis. Particularly， TCM prevention and treatment of osteoporosis by regulating the endocrine system has received extensive attention. By reviewing relevant literature， this paper introduces the research progress in the TCM modulation of bone metabolism and alleviation of bone loss by regulating estrogen， calcitonin， and parathyroid hormone in the endocrine system and affecting the hypothalamus capable of regulating these hormones， aiming to provide ideas for the TCM treatment of osteoporosis.

Exploration on the blended learning reform in organ-systems based curriculum model of the endocrine system / 中华医学教育探索杂志

Since 2016, Binzhou Medical University began to carry out the blended learning reform in the organ-systems based curriculum (OSBC) of the experimental class of clinical medicine. Based on the traditional face-to-face teaching method, the blended learning mode of the integrated course of endocrine system under OSBC has been carried out by using the small private online course (SPOC) of MOOC platform of China universities. Many teaching methods have been adopted and formed, including case-based learning (CBL), problem-based learning (PBL), professional bilingual teaching, scientific research teaching and virtual simulation experiment teaching. The evaluation system for the combination of formative and summary assessment has been also adopted in the whole process to assess the students' academic achievement, and the teaching effect as well. The blended learning mode of the integrated course of the endocrine system under OSBC is still in the exploratory stage. There are some limitations, such as too high requirements for teachers' quality, long preparation time for teaching, and great difficulty in supervising online learning. However, the practice of teaching reform that has been carried out shows that it is effective, feasible, and worth popularizing.

Introduction: Thyroid diseases are relatively frequent; they constitute an important group within chronic non-communicable diseases. Objective: To determine the quality of life in patients with thyroid diseases. Methods: An observational, descriptive and cross-sectional study was carried out. The universe (210 patients) with a diagnosis of thyroid diseases, who met the inclusion and exclusion criteria provided for in the study, prior informed consent, and the non-probabilistic sample (198 patients). The variables used were: age, sex, diagnosed thyroid disease (hyperthyroidism, hypothyroidism, diffuse euthyroid goiter) and quality of life (facets according to dimensions, according to expert classification and thyroid diseases and comprehensive quality of life according to diseases thyroid). The World Health Organization Quality of Life questionnaire was used. Results: Hypothyroidism predominated as the most frequent thyroid condition in women between 50 and 59 years of age. The clinical manifestations that scored the lowest average were pain and discomfort, followed by medical indications and negative feelings; the physical and psychological dimensions scored with low averages, as well as the environment, values ​​considered deficient. Conclusions: An average comprehensive quality of life prevailed in the highest percentage of patients; these diseases must be identified in time, to avoid other complications in different body systems that could compromise the patient's life.

Immune checkpoint inhibitor-induced endocrinopathies: a possible indicator of improved survival

ABSTRACT Objective: To evaluate the association between the patients' characteristics and the development of endocrine toxicity and to assess the association between endocrine-related adverse effects (ERAE) development and mortality. Subjects and methods: A retrospective observational study was conducted in 98 patients submitted to immunotherapy in our centre since its introduction in 2015 until March 2021. We excluded patients for which data regarding the corticotroph axis evaluation was missing. We used linear and logistic regression models to address our aims. Results: We observed a significant negative association between ERAE development and death (OR 0.32; p = 0.028). We detected no associations between ERAE and the following characteristics: age at immune checkpoint inhibitors (ICI) initiation, sex, diabetes mellitus, medical history, immunotherapy duration and ICI type. Conclusion: The development of an ERAE may be associated with a better overall survival rate in advanced oncologic disease, supporting the role of an unleashed immune system response to malignant cells.

Síndrome POEMS: desafios no diagnóstico de um caso atípico / POEMS syndrome: challenges in the diagnosis of an atypical case

Introdução: Síndrome POEMS trata de um raro evento paraneoplásico, sem relato atual na literatura sobre sua real prevalência. A maior parte dos casos ocorre em homens de meia idade. Relato do Caso:Paciente masculino, 65 anos, com queixa edema e parestesia em pernas que evoluiu para plegia, associada a hiporexia e fadiga. Investigação ambulatorial inicial evidenciou Polirradiculoneuropatia Inflamatória Desmielinizante Crônica (PIDC) de etiologia indefinida. Excluídos secundarismos, o paciente foi diagnosticado com hipotireoidismo primário, hipogonadismo severo, lesões hipercrômicas em pele, ascite, derrame pleural e trombocitose, além de gamopatia monoclonal IgA Lambda por imunofixação sérica. Sorologias virais negativas. Excluída a possibilidade de Mieloma Múltiplo e outras gamopatias, foi aventada a hipótese de Síndrome POEMS, sendo realizada dosagem de VEGF plasmática (425 pg/mL; VR = <96.2). Trata-se de um caso atípico na medida em que, lesões ósseas, presentes em até 97% dos casos, não foram evidenciadas no paciente em questão, tornando desafiador o diagnóstico. Conclusões: O diagnóstico de síndromes raras, embora desafiante, traz ao clínico um olhar mais amplo do paciente na medida em que incrementa o raciocínio clínico. [au]

Introduction: POEMS syndrome is a rare paraneoplastic event, with no current report in the literature about its real prevalence. Most cases occur in middle-aged men. Case Report: Male patient, 65 years old, complaining of edema and paresthesia in the legs that evolved to plegia, associated with hyporexia and fatigue. Initial outpatient investigation revealed Chronic Inflammatory Demyelinating Polyradiculoneuropathy (CIDP) of undefined etiology. Excluding secondaries, the patient was diagnosed with primary hypothyroidism, severe hypogonadism, hyperchromic skin lesions, ascites, pleural effusion and thrombocytosis, in addition to monoclonal IgA Lambda gammopathy by serum immunofixation. Viral serologies was negative. Excluding the possibility of Multiple Myeloma and other gammopathies, the hypothesis of POEMS Syndrome was raised, and plasma VEGF measurement was performed (425 pg/mL; RV = <96.2). This is an atypical case in that bone lesions, present in up to 97% of cases, were not evidenced in the patient in question, making the diagnosis challenging. Conclusions: The diagnosis of rare syndromes, although challenging, brings the clinician a broader view of the patient as it increases clinical reasoning. [au]

Interacción del microbioma intestinal y el hueso / Interaction between the intestinal microbiome and bone

El "microbioma" no solo está constituido por los microbios, sino por todos los componen-tes que viven en el mismo hábitat conforman-do un nicho ecológico. Es decir, está conformado por los microorganismos (bacterias, hongos, protozoos, etc.), todo el espectro de moléculas producidas por ellos tales como sus componentes estructurales (ácidos nucleicos, proteínas, lípidos y glúcidos), meta-bolitos, toxinas, etc., y las moléculas producidas por el huésped. El microbioma intestinal (MI) ha emergido como un factor que tiene un gran efecto sobre la cantidad, calidad y fuerza del hueso. Las investigaciones revelan que la homeostasis ósea está ligada al micro-bioma saludable, mientras que la disbiosis (alteración en la biodiversidad microbiana) puede exacerbar la actividad osteoclástica y promover la osteoporosis. Los mecanismos potenciales involucrados en la interacción del microbioma intestinal y el hueso son la influencia del metabolismo del huésped, el mantenimiento de la integridad intestinal y regulación de la absorción de nutrientes, la regulación del eje intestino-sistema inmune y la modulación del sistema endocrino. Es decir que hay múltiples vías por las cuales el MI influye sobre el hueso, pero estos y otros mecanismos deben profundizarse más aún. También es necesario que se identifiquen y caractericen mejor los microorganismos que están asociados a las enfermedades óseas. El conocimiento de estos aspectos podría ser útil para el desarrollo de herramientas terapéuticas basadas en el MI que puedan mejorar la eficacia de los distintos tratamientos existentes. (AU)

The microbiome is not only constituted by microbes, but by all the components that live in the same habitat forming an ecological niche. It is conformed by the microorganisms ( bacteria, fungi, protozoa, etc), the entire spectrum of molecules produced by them (nucleic acids, proteins, lipid and carbohydrates, metabolites, toxins, etc) and the molecules produced by the host. The intestinal microbiome (IM) has emerged as a factor with great effects on the quantity, quality and strength of bone. The investigations reveal that bone homeostasis is linked to the healthy microbiome, while the dysbiosis (alteration in the microbial biodiversity) can exacerbate the osteoclastic activity and promote osteoporosis. The potential mechanisms involved in the interaction between IM and bone are the influence of the host metabolism, the maintenance of the intestinal integrity and regulation of the nutrient absorption, the regulation of the intestine/ immune system axis and the modulation of the endocrine system. That is, there are multiple ways through which IM influences on bone, but these and other mechanisms need to be further studied. It is also necessary to identify and characterize the microorganisms associated with the bone diseases. Knowledge of these aspects could be useful to develop therapeutical tools based on the IM that could improve the efficacy of the current treatments. (AU)

Construction and validation of a nomogram prediction model of fatty liver occurrence in postoperative breast cancer patients after endocrine therapy / 肿瘤研究与临床

Objective:To explore the risk factors of fatty liver occurrence in postoperative breast cancer patients after endocrine therapy, and establish a risk prediction model.Methods:A total of 120 breast cancer patients who received endocrine therapy after surgery in Huanggang Central Hospital from June 2014 to June 2016 were retrospectively selected, and another 120 breast cancer patients who did not receive endocrine therapy after surgery in the same period were selected as the control group. The difference of prognosis between patients treated with endocrine therapy or not was compared. According to the occurrence of fatty liver after endocrine therapy, the patients were divided into fatty liver group (63 cases) and non-fatty liver group (57 cases). Multivariate logistic regression was used to analyze the risk factors of fatty liver occurrence after endocrine therapy. Based on the risk factors, R 3.3.2 software was used to establish a nomogram prediction model. The Harrell consistency index and receiver operating characteristic (ROC) curve (with imageological diagnosis as the "gold standard") were used to analyze the effect of the model on predicting the occurrence of fatty liver, and the calibration curve was used to evaluate the consistency between the model prediction and the actual situation.Results:The recurrence and metastasis rate and mortality rate of patients with endocrine therapy were lower than those of patients without endocrine therapy, and the 3-year and 5-year disease-free survival rates and overall survival rates were higher than those of patients without endocrine therapy (all P < 0.05). Compared with the non-fatty liver group, the levels of alanine transaminase (ALT), aspartate transaminase (AST), total bilirubin (TBIL), total cholesterol (TC), triglyceride (TG), low-density lipoprotein cholesterol (LDL-C) and body mass index (BMI) in the fatty liver group increased (all P < 0.05), while the level of high-density lipoprotein cholesterol (HDL-C) decreased ( P < 0.05). Multivariate logistic regression analysis showed that increased ALT [ OR = 4.680 (95% CI 3.621-5.738)], AST [ OR = 4.862 (95% CI 3.809-5.914)], TBIL [ OR = 3.808 (95 % CI 2.754-4.861)], TC [ OR = 4.294 (95% CI 3.320-5.267)], TG [ OR = 3.401 (95% CI 2.442-4.359)], LDL-C [ OR = 2.976 (95% CI 2.037-3.916)], BMI [ OR = 4.082 (95% CI 3.118-5.045)] and decreased HDL-C [ OR = 0.930 (95% CI 0.876-0.983)] were independent risk factors for fatty liver occurrence after endocrine therapy (all P < 0.05). The consistency index of the nomogram model was 0.792 (95% CI 0.721-0.863), and the area under the ROC curve (AUC) of the nomogram model to judge the occurrence of fatty liver was 0.810 (95% CI 0.734-0.886), indicating that the model had a good discrimination between fatty liver and non-fatty liver. The evaluation of calibration curve showed that the nomogram model for prediction of fatty liver had a good consistency with the actual occurrence of fatty liver. Conclusions:Increased ALT, AST, TBIL, TC, TG, LDL-C, BMI and decreased HDL-C are risk factors for fatty liver occurrence after endocrine therapy in postoperative breast cancer patients. The nomogram model based on risk factors has a good effect on predicting the occurrence of fatty liver.

Síndrome POEMS: desafios no diagnóstico de um caso atípico / POEMS syndrome: challenges in the diagnosis of an atypical case

Introdução: Síndrome POEMS trata de um raro evento paraneoplásico, sem relato atual na literatura sobre sua real prevalência. A maior parte dos casos ocorre em homens de meia idade; Relato do Caso: Relatamos o caso de um paciente masculino, 65 anos, admitido com queixa edema e parestesia em pernas que evoluiu para plegia, associada a hiporexia e fadiga. Investigação ambulatorial inicial evidenciou polirradiculoneuropatia inflamatória desmielinizante crônica (PIDC) de etiologia indefinida. Excluídos secundarismos para polirradiculoneuropatia inflamatória desmielinizante crônica, o paciente foi a seguir diagnosticado com hipotireoidismo primário, hipogonadismo severo, lesões hipercrômicas em pele, ascite, derrame pleural e trombocitose, além de gamopatia monoclonal IgA Lambda por imunofixação sérica. Sorologias para HIV, Sífilis e Hepatites todas negativas. Excluída a possibilidade de Mieloma Múltiplo e outras gamopatias, foi aventada a hipótese de Síndrome POEMS, sendo realizada dosagem de Fator de Crescimento Endotelial Vascular (VEGF) plasmática (425 pg/mL; VR = <96.2). O paciente passou então a preencher os critérios obrigatórios para diagnóstico, além de um maior (VEGF elevada) e vários outros menores. Trata-se de um caso atípico na medida em que, lesões ósseas, presentes em até 97% dos casos, não foram evidenciadas no paciente em questão, tornando desafiador o diagnóstico e sendo então necessário recorrer à dosagem de VEGF. O diagnóstico de síndromes raras, embora desafiante, traz ao clínico um olhar mais amplo do paciente na medida em que incrementa o raciocínio clínico. Difundir e explorar esse universo é cada vez mais necessário

Introduction: POEMS syndrome is a rare paraneoplastic event, with no current report in the literature about its real prevalence. Most cases occur in middle-aged men; Case Report: We report the case of a male patient, 65 years old, admitted with complaints of edema and paresthesia in the legs that progressed to plegia, associated with hyporexia and fatigue. Initial outpatient investigation revealed Chronic Inflammatory Demyelinating Polyradiculoneuropathy (CIDP) of undefined etiology. Excluding secondaries for chronic inflammatory demyelinating polyradiculoneuropathy, the patient was subsequently diagnosed with primary hypothyroidism, severe hypogonadism, hyperchromic skin lesions, ascites, pleural effusion and thrombocytosis, in addition to monoclonal IgA Lambda gammopathy by serum immunofixation. All serologies for HIV, Hepatitis and syphilis were negative. Excluding the possibility of Multiple Myeloma and other gammopathies, the hypothesis of POEMS Syndrome was raised, and plasma Vascular Endotelial Growth Factor (VEGF) measurement was performed (425 pg/mL; RV = <96.2). The patient then started to fulfill the mandatory criteria for diagnosis, in addition to a major (elevated VEGF) and several other minors. This is an atypical case in that bone lesions, present in up to 97% of the cases, were not evidenced in the patient in question, making the diagnosis challenging and therefore requiring the use of VEGF dosage. The diagnosis of rare syndromes, although challenging, brings the clinician a broader view of the patient as it increases clinical reasoning. Spreading and exploring this universe is increasingly necessary

Aumento da Rigidez Arterial Pulmonar e Comprometimento do Acoplamento Ventrículo Direito-Artéria Pulmonar na SOP / Increased Pulmonary Arterial Stiffness and Impaired Right Ventricle-Pulmonary Artery Coupling In PCOS

Resumo Fundamento: A síndrome dos ovários policísticos (SOP) é a doença endócrino-metabólica mais comum em mulheres em idade reprodutiva, e ocorre em uma a cada 10 mulheres. A doença inclui irregularidade menstrual e excesso de hormônios masculinos e é a causa mais comum de infertilidade em mulheres. A dispneia é um sintoma frequente e muitas vezes acredita-se que seja decorrente da obesidade, mas não se sabe se é decorrente de disfunção cardíaca. Objetivo: Avaliar o acoplamento ventrículo-arterial (VDAP) e a rigidez arterial pulmonar em pacientes com SOP. Métodos: Foram incluídos 44 pacientes com SOP e 60 controles; amostras de sangue venoso foram coletadas para exames laboratoriais e ecocardiograma transtorácico 2-D, Modo-M e com Doppler tecidual foram realizados em todos os participantes. Um valor de p<0,05 foi considerado estatisticamente significativo. Resultados: Quando comparadas ao grupo controle, as pacientes com SOP apresentaram valores maiores de rigidez da artéria pulmonar (p = 0,001), que se correlacionaram positivamente com o índice HOMA-IR (r = 0,545 e p <0,001). O acoplamento VDAP também estava comprometido em 34% dos pacientes do estudo. Conclusão: A rigidez da artéria pulmonar está aumentada e o acoplamento VDAP está comprometido em pacientes com SOP.

Abstract Background: Polycystic ovary syndrome (PCOS) is the most common endocrine-metabolic disease in women in reproductive age, and occurs in one of 10 women. The disease includes menstrual irregularity and excess of male hormones and is the most common cause of female infertility. Dyspnea is a frequent symptom and is often thought to be due to obesity, and whether it is due to cardiac dysfunction is unknown. Objective: To evaluate right ventricle-pulmonary artery (RV-PA) coupling and pulmonary arterial stiffness in patients with PCOS. Methods: 44 PCOS patients and 60 controls were included; venous blood samples were taken for laboratory tests and 2-D, m-mode and tissue doppler transthoracic echocardiography were performed for all the participants. P<0,05 was considered as statistically significant. Results: When compared to the control group, PCOS patients had higher pulmonary artery stiffness values (p=0,001), which were positively correlated with HOMA-IR (r=0,545 and p<0,001). RV-PA coupling was also impaired in 34% of the study patients. Conclusion: Pulmonary artery stiffness is increased and RV-PA coupling is impaired in patients with PCOS.

Convulsiones, derrame pericárdico y rabdomiólisis en debut de coma mixedematoso / Myxedema coma presenting with seizures, pericardial effusion, and rhabdomyolysis

RESUMEN El coma mixedematoso es la complicación más grave de un hipotiroidismo. Ocurre, por lo general, en mujeres ancianas con hipotiroidismo conocido sin un adecuado manejo y en presencia de un evento desencadenante. El diagnóstico es difícil y debe realizarse en forma oportuna para disminuir el riesgo de muerte. El coma es una de las presentaciones neurológicas de esta urgencia endocrinológica y no es necesario su presencia para el diagnóstico. En este reporte de caso se presentan varías manifestaciones inusuales en un paciente masculino con hipotiroidismo profundo que, al diagnóstico, debutó con coma mixedematoso con predictores de mal pronóstico durante la hospitalización, pero debido al abordaje temprano y el manejo integral, se dio una resolución satisfactoria a esta urgencia endocrinológica infrecuente.

SUMMARY Myxedema coma is the most serious complication of hypothyroidism. It usually occurs in the context of elderly women, with known hypothyroidism without proper management and in the presence of a triggering event. The diagnosis is challenging and must be made in a timely manner to prevent the development of adverse outcomes. Coma is one of the neurological manifestations of the entity, not being necessary for its diagnosis. This case report presents a constellation of unusual manifestations of a male patient with myxedema coma at the debut of severe hypothyroidism with predictors of poor prognosis during hospitalization, but due to the early approach and comprehensive management, this uncommon endocrinological emergency was satisfactorily resolved.

Research advances in extrahepatic diseases associated with nonalcoholic fatty liver disease / 临床肝胆病杂志

Nonalcoholic fatty liver disease (NAFLD) is a major cause of chronic liver diseases worldwide and covers a series of pathological manifestations from hepatic steatosis to inflammation, fibrosis, and even liver cirrhosis. NAFLD is associated with a wide range of extrahepatic diseases, including metabolic syndrome, cardiovascular disease, chronic kidney disease, endocrine diseases, obstructive sleep apnea-hypopnea syndrome, psoriasis, and skeleton-muscle diseases. The major causes of death in patients with NAFLD include cardiovascular disease, malignancies, and liver-related complications, suggesting that extrahepatic diseases associated with NAFLD should be taken seriously by clinicians. This article reviews the research advances in extrahepatic diseases associated with NAFLD, so as to provide ideas for clinical assessment and treatment.

Research progress on the effect of shift-work on the physical health of nurses / 中国职业医学

Good health status is an important prerequisite for nurses to provide quality nursing services for patients. Shift-work is an important work style of nurses. Studying the effect of shift-work on the physical health of nurses is helpful for planning a reasonable shift-work system, formulating health promotion strategies, and improving the personal health and quality of life of nurses. Shift-work can disrupt circadian rhythms and lead to dysfunction autonomic and endocrine system, indirectly increasing the risk of disease for nurses. Some research suggests that shift-work may have an impact on the endocrine system, leading to an increased risk of diabetes, metabolic syndrome and sleep disorders. Shift-work can cause dysregulation of the parasympathetic nervous system, leading to an increased risk of cardiovascular disease and increased mortality from cardiovascular disease in nurses. Shift-work may cause acid-base imbalance and changes in digestive enzyme secretion, leading to an increased risk of digestive diseases. However, the current research on the effect of shift-work on the physical health of nurses is lacking and more rigorous studies are needed.

Comparative assessment of effect of malt with different bud length on prolactin in hyperprolactinemia rat

Malt is the mature fruit of Hordeum vulgare L. after germination and drying and has been applied for treatment female abnormal galactorrhea. Previous studies have showed total alkaloids in malt have anti-HPRL effect. However, total alkaloids of malt change with the growth cycle, and the specified levels of total alkaloids in different bud length of malt have not been decided. To determine the definitive level of total alkaloids in different buds of malt and the most suitable bud length for clinical application by comparing effects on hyperprolactinemia rat. During the budding of malt, the content of total alkaloids first increased and then decreased, and it peaked at a bud length of 0.75 cm. Treated the HPRL model rats with different buds of malt, the PRL level was decreased, the number of PRLpositive cells and the mRNA expression level in the pituitary were significantly declined, and the number of dopamine D1 and D2 receptors in the hypothalamus was increased. The above changes were most significant in 0.75 cm bud. These results suggest that in terms of the content of effective substance and the effects on HPRL model rats, a malt bud length of 0.75 cm is optimal for clinical application.

Efectos de los opioides en endocrinología / Opioids effects in endocrinology

El uso de opioides ha aumentado en forma significativa en las últimas décadas, lo que nos ha permitido conocer sus diversos efectos en el sistema endocrino. Estos efectos están sub diagnosticados, en parte porque los síntomas se confunden con los de la misma enfermedad que lleva al uso de opioides y porque no los buscamos de forma dirigida. El hipogonadismo y la insuficiencia suprarrenal son sus efectos más establecidos, sin embargo, otros efectos como los provocados en el tejido óseo requieren de especial atención. La evaluación de los ejes gonadotropo, adrenal y de la salud ósea debe tenerse en consideración en los usuarios crónicos de opioides, particularmente frente a la presencia de síntomas. La suspensión o reducción del uso de opioides es el primer tratamiento del compromiso endocrinológico.

The use of opioids has increased significantly in recent decades, which has allowed us to understand its effects on the endocrine system. These effects are underdiagnosed, the symptoms are confused with those of the same disease that leads to the use of opioids and we do not look for them in a targeted way. Hypogonadism and adrenal insufficiency are its most established effects, however, other effects such as the ones caused on bone tissue require special attention. Evaluation of gonadotropic and adrenal axes as well as bone health should be taken into consideration in chronic opioid users, particularly in the presence of symptoms.

Calcinose enzoótica, causada por Nierembergia rivularis, no Uruguai, e Nierembergia veitchii, no Brasil, é uma doença caracterizada por mineralização de tecidos moles, hiperplasia das células parafoliculares da tireoide e elevação nos níveis de cálcio e fósforo. Descreve-se um caso de hiperplasia e carcinoma de células parafoliculares bilateral em um ovino de quatro anos, com calcinose enzoótica associada à intoxicação por Nierembergia rivularis. O diagnóstico histológico de hiperplasia e carcinoma de células parafoliculares é suportado pelas marcações imuno-histoquímicas positivas para calcitonina, peptídeo relacionado ao gene da calcitonina e enolase neurônio específica. Como a hiperplasia de células parafoliculares é uma lesão pré-neoplásica induzida por hipercalcemia, sugere-se que a hipercalcemia crônica causada pela intoxicação por N. rivularis pode ter induzido hiperplasia de células parafoliculares seguida de transformação em carcinoma, neste caso. Os efeitos carcinogênicos das plantas calcinogênicas no sistema endócrino devem ser melhor explorados.(AU)

Recomendaciones para el uso de la hormona de crecimiento humana recombinante en pacientes pediátricos de talla baja en Colombia / Recommendations for treatment with recombinant human growth hormone in pediatric patients in Colombia

resumen está disponible en el texto completo

Abstract In Colombia there are no guidelines for diagnosis and management of patients with short stature and for the use of recombinant human growth hormone, mainly caused by the diversity of training centers in pediatric endocrinology. In response to this situation, the Asociación Colegio Colombiana de Endocrinología Pediátrica leds the first colombian short stature expert committee in order to standardize the use of human recombinant growth hormone. This work had the participation and endorsement of a consortium of clinical experts representing the Sociedad Colombiana de Pediatría, Secretaría Distrital de Salud de Bogotá- Subred Integrada de Servicios de Salud Suroccidente, Fundación Universitaria Sanitas, Universidad de los Andes and some public and private health institutions in the country, in addition to the participation of methodological experts from the Instituto Global de Excelencia Clínica Keralty. By reviewing the literature and with the best available evidence, we proposed to unify definitions, a diagnostic algorithm, biochemical and dynamic tests with their reference parameters, a description of the considerations about growth hormone use among the indications approved by regulatory agency for medications and food in Colombia and finally a proposal for an informed consent and a medication fact sheet available for parents and patients.

Problemas gastrointestinales, nutricionales, endocrinológicos y de microbiota en el trastorno del espectro autista / Gastrointestinal, nutritional, endocrine, and microbiota conditions in autism spectrum disorder

Los problemas médicos gastrointestinales, nutricionales, metabólicos, endocrinológicos y de microbiota en los pacientes pediátricos con diagnóstico de trastorno del espectro autista (TEA) son parte de los problemas médicos concomitantes al diagnóstico. La prevalencia alcanza a más del 91 % en el caso de los problemas gastrointestinales, hasta el 89 % para los nutricionales y metabólicos, más del 50 % de disfunción tiroidea y hasta el 100 % para los relacionados con la microbiota.Es urgente actualizar la práctica médica para incluir la evaluación, testeo, diagnóstico y tratamiento de estos problemas médicos concomitantes al diagnóstico de TEA en la población pediátrica, adolescente y adulta. El tratamiento riguroso de dichos problemas genera cambios positivos en la calidad de vida y en la sintomatología bajo la cual el TEA se diagnostica en muchos casos. Debe basarse en evidencia científica de alta calidad, con control y cuidado médico adecuado

Gastrointestinal, nutritional, metabolic, endocrine, and microbiota medical problems in pediatric patients diagnosed with autism spectrum disorder (ASD) are some of the coexisting medical conditions in ASD diagnosis. Their prevalence reaches more than 91 % for gastrointestinal problems, up to 89 % for nutritional and metabolic disorders, more than 50 % for thyroid dysfunction, and up to 100 % for microbiota-related conditions.There is an urgency for medical practice to be updated and to include the assessment, testing, diagnosis, and treatment of these coexisting medical conditions in ASD diagnosis in the pediatric, adolescent, and adult population. A strict management of such conditions results in positive changes in the quality of life and symptoms based on which ASD is diagnosed many times. It should be based on high-quality scientific evidence with an adequate medical care and control
