Serum Uric Acid Level and Its Influencing Factors in Patients with Diabetes Insipidus / 中国医学科学院学报

Objective To investigate the level of serum uric acid in patients with diabetes insipidus (DI),summarize the clinical characteristics of central diabetes insipidus (CDI) patients with hyperuricemia (HUA),and analyze the factors affecting the level of serum uric acid in the patients with CDI. Methods The clinical data of DI patients admitted to Peking Union Medical College Hospital from 2018 to 2021 were retrospectively analyzed.The patients were assigned into a child and adolescent group (≤ 18 years old) and an adult group (>18 years old) according to their ages.The demographic and biochemical data between two groups of patients with and without HUA were compared.Spearman correlation analysis and multiple linear regression analysis were performed to analyze the correlations between serum uric acid level and other factors. Results Among the 420 DI patients,411 patients had CDI (97.9%),including 189 patients with HUA (46.0%).Thirteen (6.9%) out of the 189 CDI patients with HUA presented the disappearance of thirst.The prevalence of HUA in children and adolescents was higher than that in adults (χ2=4.193,P=0.041).The level of serum uric acid in the CDI patients with HUA and disappearance of thirst was higher than those without disappearance of thirst (U=2.593,P=0.010).The multiple linear regression predicted serum creatinine (β=0.472,95%CI=2.451-4.381,P<0.001) and body mass index (β=0.387,95%CI=6.18-12.874,P<0.001) as the independent risk factors of serum uric acid level increment in children and adolescents,while serum creatinine (β=0.361,95%CI=1.016-1.785,P<0.001),body mass index (β=0.208,95%CI=2.321-6.702,P<0.001),triglyceride (β=0.268,95%CI=12.936-28.840,P<0.001),and total cholesterol (β=0.129,95%CI=2.708-22.250,P=0.013) were the independent risk factors in adults. Conclusions The patients with CDI were more likely to have HUA,and the prevalence of HUA in children and adolescents was higher than that in adults.Body mass index,serum creatinine,triglyceride,total cholesterol,and disappearance of thirst were the risk factors for the increased level of serum uric acid in CDI patients.

Treatment Outcomes in COVID-19 patients with comorbidities in Kaduna state, NorthwesternNigeria

Background: Severe COVID-19 disease has been reported among people with underlying conditions such as diabetes, chronic respiratory diseases, cancer, obesity, and cardiovascular disease. This study determined the outcomes of COVID-19 among patients with comorbidities in Kaduna state, where we have the highest incidence in northern Nigeria.Methods: This study was a retrospective, descriptive cross-sectional review of the clinical records involving all age groups of 902 COVID-19 patients admitted at the four isolation centers of the Kaduna State Infectious Disease Control Centre (IDCC) between March 27th2020 to December 31st2021. Data was analyzed with SPSS version 25 and STATA SE 12 with p <0.05.Results: Out of the 902 cases, 245(27.2%) had comorbidities, hypertension 206(22.8%) was the most recorded comorbidity, others were diabetes 77(8.5%), asthma 7 (0.78%), HIV 7(0.78%), sickle cell anemia 7 (0.78%) and PTB 3 (0.33%). Patients with comorbidities had prolonged mean duration of symptoms 8.36±3.5 days, compared to 7.2±2.7 days in those without comorbidities (p=0.001).Multivariate logistic regression analysis further shows that the odds for clinical recovery from the COVID-19 disease was significantly lower for patient with hypertension (AOR=0.13, 95%CI=0.06-0.27, p = <0.01), diabetic (AOR=0.20, 95% CI=0.10-0.40, p<0.01) and HIV comorbidities (AOR=0.1, 95%CI=0.01-0.98, p=0.05) compared to those without comorbiditiesConclusion: Hypertension and diabetes were the major comorbidities in this study. Most patients with comorbidities had severe presentations and fatal poorer outcome. There is a need for sustained public health education targeted at patients with chronic diseases to be screened and treated early for COVID 19 Disease

Treatment outcome of a β-hCG Secreting Intracranial Germ Cell Tumorin an adult Filipino using definitive Chemotherapy followed by Radiotherapy: A case report / Journal of the ASEAN Federation of Endocrine Societies

@#We report a case of a 24-year-old Filipino male who complained of general weakness, polydipsia, weight loss, bitemporal headaches, loss of libido and behavioral changes. Endocrine work-up revealed neurogenic diabetes insipidus and panhypopituitarism. Brain MRI showed multiple intracranial tumors in the left frontal lobe, pineal and suprasellar region with moderate non-communicating hydrocephalus. Intracranial mass biopsy with ventriculo-peritoneal shunting was done. Histopathology of the mass and CSF revealed a germinoma. He underwent chemoradiotherapy while on maintenance hormone replacement.

Diagnóstico diferencial de adenoma folicular y carcinoma papilar de tiroides mediante variables cariométricas. Matanzas 2013-2016 / Differential diagnosis of thyroidal follicular adenoma and papillary carcinoma by means of karyometric variables. Matanzas 2013-2016

RESUMEN Introducción: los carcinomas diferenciados de tiroides se originan en el epitelio folicular. De ellos el carcinoma papilar muestra una mayor incidencia. Una variante del mismo es la folicular, que en ocasiones muestra un patrón arquitectural que imita a un adenoma folicular. Objetivo: contribuir al diagnóstico diferencial entre el carcinoma papilar variante folicular y el adenoma folicular de tiroides, utilizando variables cariométricas de las células foliculares. Materiales y métodos: se aplicaron técnicas morfométricas a muestras de biopsias de tiroides con carcinoma papilar variante folicular y adenoma folicular, así como a muestras sin patología, en el período comprendido de enero de 2013 a diciembre de 2016, obtenidas en el Hospital Universitario Clínico Quirúrgico Comandante Faustino Pérez Hernández, de Matanzas. Las técnicas aplicadas se basaron en las variables cuantitativas: área, perímetro y factor de forma nuclear de las células foliculares. Los resultados se expresaron en porcentajes; la media aritmética como medida de tendencia central; desviación típica, incluyéndose el cálculo de los valores máximo, mínimo y recorrido para cada variable comprendida en el estudio, reflejados en tablas y gráficos realizados a través del software Microsoft Office Excel. Resultados: se obtuvieron valores elevados de área y perímetro nuclear de las células foliculares del carcinoma papilar variante folicular con relación al adenoma folicular, mientras que el factor de forma no arrojó resultados significativos para la diferenciación de dichas enfermedades tiroideas. Conclusiones: la aplicación de técnicas morfométricas a variables cariométricas en el tiroides, para el diagnóstico diferencial entre el carcinoma papilar variante folicular y el adenoma folicular, ofrece resultados aplicables en estudios histopatológicos (AU).

ABSTRACT Introduction: differentiated thyroid carcinomas are originated in the follicular epithelium. Of them, the papillary carcinoma shows higher incidence. Follicular carcinoma, one of its variants, occasionally shows an architectural pattern imitating a follicular adenoma. Objective: to contribute to the differential diagnosis between the papillary carcinoma, follicular variant, and thyroid follicular adenoma, using karyometric variables of follicular cells. Materials and methods: morphometric techniques were applied to samples of biopsies of thyroids with papillary carcinoma, follicular variant, and follicular adenoma, and also to samples without any pathology, in the period from January 2013 to December 2016, gathered in the University Hospital Comandante Faustino Perez, of Matanzas. The applied techniques were based on quantitative variables: area, perimeter and nuclear form factor. Results were expressed in percentages; the arithmetic median as measure of central tendency; typical deviation, including the calculation of maximal, minimal values and the course for each variable included in the study, were drawn in tables and graphics using Microsoft Office Excel software. Results: highs values of area and nuclear perimeter of the follicular cells of the papillary carcinoma, follicular variant, were obtained, while the shape factor did not show significant results for those thyroidal diseases differentiation. Conclusions: the application of morphometric techniques to karyometric variables in the thyroids, for the differential diagnosis between the papillary carcinoma, follicular variant, in follicular carcinoma, offers results that can be applied in histopathological studies (AU).

Diabetes Insipidus Induced by Combination of Short-acting Octreotide and Lanreotide for Recurrent Carcinoid Crisis of Neuroendocrine Tumour: A case report / Journal of the ASEAN Federation of Endocrine Societies

@#Somatostatin analogue is useful in carcinoid crisis for symptom control. Optimal dosing of somatostatin analogues for carcinoid symptoms is not known. This case highlighted management issues using combination short-acting octreotide infusion with long-acting lanreotide during carcinoid crisis. The patient had left lung neuroendocrine tumour that metastasized to his liver and bone, post left lobectomy. Due to extensive metastasis to the liver causing recurrent carcinoid crisis, he required shorter interval long-acting lanreotide with continuous infusion of short-acting octreotide, which led to transient diabetes insipidus. Symptoms resolved with discontinuation of treatment. Somatostatin analogues, especially in combination, may inhibit the posterior pituitary resulting in diabetes insipidus. Prompt withdrawal of short-acting somatostatin analogue and initiation of desmopressin can reverse the complication. It is important to recognize this complication with combination of octreotide and lanreotide injections to avoid serious complications.

Diabetes insípida y virus del Zika / Diabetes insipid us and Zika virus

La diabetes insípida es el resultado de una secreción o acción reducidas de la hormona vasopresina, expresada clínicamente por un cuadro de poliuria-polidipsia. Los arbovirus pueden tener afinidad por el sistema nervioso y se ha demostrado que el Zika desencadena un trastorno autoinmune que ataca a las células nerviosas, lo que puede traer como consecuencia una diabetes insípida central. En la literatura médica nacional e internacional revisada no se reportan casos anteriores donde se vincule la diabetes insípida con el virus del Zika. Se presenta un caso a propósito de esta asociación: paciente femenina de 53 años, diagnosticada con infección por el virus del Zika dos semanas antes de comenzar con los síntomas sugestivos de diabetes insípida. El potencial neurotrópico del virus, así como los resultados en la resonancia magnética nuclear y la determinación de marcadores de autoinmunidad anti-ADNdc positivos, son elementos que apoyan la hipótesis de que la paciente presentó una posible hipofisitis autoinmune, como respuesta inflamatoria post-infección, desarrollando diabetes insípida central transitoria(AU)

Diabetes insipidus is the result of reduced secretion or action of the vasopressin hormone, which is clinically expressed by a polyuria-polydipsia picture. Arboviruses can have a nervous system affinity and Zika has been shown to trigger an autoimmune disorder that attacks nerve cells, which can result in central diabetes insipidus. The reviewed national and international medical literatures does not report previous cases linking diabetes insipidus with Zika virus. It is presented a case about this association: 53-year-old female patient diagnosed with Zika virus infection two weeks before starting symptoms suggestive of diabetes insipidus. The neurotropic potential of the virus, as well as the results in nuclear MRI and the determination of positive anti-ADNdc autoimmunity markers are elements that support the hypothesis that the patient had a possible autoimmune hypophysis, as a post-infection inflammatory response, developing transient central diabetes insipidus(AU)

Case report of a Pituitary Metastasis from Lung Adenocarcinoma Masquerading as Pituitary Adenoma / Journal of the ASEAN Federation of Endocrine Societies

@#Metastasis to the pituitary gland is an unusual situation in clinical practice and is typically observed in those with underlying malignancy with breast and lung being the commonest primary site. However, we report a case of an apparently well 49-year-old female with metastatic lung adenocarcinoma who presented with visual disturbance and diabetes insipidus related to pituitary metastasis as an initial presentation.

Efectos endocrinológicos tardíos del tratamiento oncológico en supervivientes de meduloblastoma / Endocrinological late effects of oncologic treatment on survivors of medulloblastoma

INTRODUCCIÓN: La radioterapia, quimioterapia y la cirugía empleada en el tratamiento de los tumores cerebrales tienen efectos en el eje hipotálamo-hipofisario y pueden resultar en disfunción endocrina hasta en el 96% de los casos. PACIENTES Y MÉTODO: Estudio retrospectivo y descriptivo en pacientes diagnos ticados de meduloblastoma sometidos a tratamiento con quimio y radioterapia en los últimos 20 años en un hospital terciario. Se analizan variables edad, sexo, peso, talla, índice de masa corporal (IMC) al final del seguimiento, estadio de maduración sexual, niveles séricos de TSH y T4 libre, ACTH/cortisol e IGF-1, FSH, LH, estradiol, testosterona, perfil lipídico (colesterol total) y prueba de función dinámica de hormona de crecimiento. RESULTADOS: Muestra total de 23 pacientes. El déficit de hormona de crecimiento es la secuela más frecuente (82 %) seguido de disfunción ti roidea (44,8%) y disfunción puberal (24,1%). Solo se diagnosticó un caso de diabetes insípida y 2 casos de déficit de corticotrofina. CONCLUSIONES: El seguimiento a largo plazo de los supervivientes de meduloblastoma tratados con quimio y radioterapia revela una prevalencia muy alta de disfun ción endocrina, particularmente de deficiencia de hormona del crecimiento y de hipotiroidismo. Creemos oportuna la monitorización y el seguimiento a largo plazo de estos pacientes con el fin de garantizar un manejo terapéutico adecuado de aquellas disfunciones tratables.

INTRODUCTION: Radiation therapy, chemotherapy, and surgery used to treat brain tumors have effects on the hy pothalamic-pituitary-adrenal axis and can result in endocrine dysfunction in up to 96% of cases. PATIENTS Y METHOD: Retrospective and descriptive study in patients diagnosed with medulloblasto ma who underwent treatment with chemo and radiotherapy in the last 20 years in a tertiary hospital. The variables analyzed were age, sex, weight, height, body mass index (BMI) at the end of follow-up, sexual maturity stage, serum levels of TSH and free T4, ACTH/cortisol and IGF-1, FSH, LH, estradiol, testosterone, lipid profile (total cholesterol), and growth hormone dynamic function test. RESULTS: Total sample of 23 patients. Growth hormone deficiency is the most frequent sequelae (82%) fo llowed by thyroid dysfunction (44.8%), and disorders of puberty (24.1%). Only one case of diabetes insipidus and two cases of corticotropin deficiency were diagnosed. CONCLUSIONS: Long-term follow- up of medulloblastoma survivors treated with chemo and radiotherapy reveals a very high prevalence of endocrine dysfunction, especially growth hormone deficiency and hypothyroidism. We believe that monitoring and long-term follow-up of these patients is necessary in order to ensure adequate therapeutic management of those treatable dysfunctions.

Diabetes insipidus secondary to tuberculous meningoencephalitis with hypothalamic involvement extending to the hypophysis: a case report

Abstract The involvement of Mycobacterium tuberculosis in the central nervous system (CNS) is an uncommon and devastating manifestation of tuberculosis. We report a case of disseminated tuberculosis presenting as meningoencephalitis, hypothalamic involvement with extension to the hypophysis, and secondary insipidus diabetes diagnosed at autopsy.

Diabetes Insípida inducida por el embarazo o gestacional: a propósito de un caso / Pregnancy or Gestational Diabetes Insipidus: a purpose of a case

RESUMEN Antecedentes: La incidencia de la diabetes insípida gestacional es aproximadamente 1/30.000 gestaciones. Objetivo: A propósito de un caso de diabetes insípida gestacional ocurrida en nuestra unidad, se decide comunicar y revisar la literatura referente a opciones de manejo y tratamiento del mismo. Caso clínico: Mujer de 38 años, primigesta de 32 semanas con clínica de poliuria y polidipsia con una ingesta hídrica diaria de hasta 7 litros. Tras realizar las pertinentes exploraciones complementarias y descartar otras patologías más frecuentes, se establece el diagnóstico de diabetes insípida gestacional. Conclusiones: La diabetes insípida gestacional es una entidad muy poco frecuente que puede desencadenar en un estado de deshidratación intensa con hipernatremia y su consecuente afectación neurológica. Es importante el diagnóstico precoz para evitar las complicaciones tanto a nivel materno como fetal, así como realizar un manejo multidisciplinar de esta patología.

ABSTRACT Background: The incidence of diabetes insipidus during pregnancy is approximately 1 in 30,000 pregnancies. Objective: We herein report a case of a patient with gestational diabetes insipidus occurring in our unit. We decided to communicate the case and review the literature regarding management and treatment options. Case report: A 38-year-old woman at 32 week of pregnancy with polyuria, polydipsia, and daily water intake of up to 7 liters. After performing the complementary tests and ruling out other more frequent conditions, the diagnosis of gestational diabetes insipidus was established. Conclusion: Gestational diabetes insipidus is a very rare entity that can cause a state of intense dehydration with hypernatremia and its consequent neurological impairment. Early detection is important in order to avoid complications of both mother and fetus, as well as to carry out a multidisciplinary management of this condition.

Langerhans Cell Histiocytosis as Cause of Central Diabetes Insipidus: Case Report

Langerhans cell histiocytosis (LCH) is a rare disease of the monocyte-macrophage system, characterized by the aberrant proliferation of specific dendritic cells. The clinical presentation ranges from a single bone lesion to widespread multiorgan involvement. This disease is usually considered to be a disease of childhood; however, the diagnosis is frequently made in adulthood. The course of the disease is fairly unpredictable and varies from spontaneous resolution to progress into a debilitating form, which compromises the vital functions with occasional fatal consequences. Langerhans cell histiocytosis exhibits a predilection for the hypothalamic-pituitary-axis, with diabetes insipidus being the most common endocrine consequence related to the disease, which may be prior to diagnosis or develop at any time during the course of the disease. The diagnosis of LCH should be based on histologic and immunophenotypic examination of a lesional biopsy, although other testing may be done, depending on the symptoms. There is no established, widely agreed-upon treatment of LCH, in general. The treatment depends upon the individual patient and the extent and areas of involvement. The present article aims to describe the case of a 26-year-old male patient whose symptoms started with a headache and occipital bone lesion that progressed later with diabetes insipidus.

A histiocitose de células de Langerhans (HCL) é uma rara doença do sistema monocítico-macrofágico, caracterizada pela proliferação aberrante de células dendríticas específicas. As manifestações clínicas variam de uma única lesão óssea a um acometimento extenso de múltiplos órgãos. Esta doença geralmente é considerada uma doença da infância; no entanto, o diagnóstico é frequentemente feito na idade adulta. O curso da doença é bastante imprevisível e varia de resolução espontânea a progressão para uma forma debilitante, com comprometimento de funções vitais e ocasionais consequências fatais. A HCL exibe uma predileção pelo eixo hipotálamohipofisário, sendo o diabetes insípido a consequência endócrina mais comum relacionada à doença, podendo ser anterior ao diagnóstico ou se desenvolver a qualquer momento durante o curso da doença. O diagnóstico de HCL deve basearse nos exames histológico e imunofenotípico de uma biópsia lesional, embora outros exames possam ser feitos a depender dos sintomas apresentados pelo paciente. Não existe um tratamento estabelecido, amplamente aceito para a HCL, em geral. O tratamento depende individualmente do paciente, da extensão e das áreas de envolvimento. O presente artigo tem como objetivo descrever o caso de um paciente do sexo masculino de 26 anos de idade que iniciou o quadro com uma cefaleia e lesão óssea occipital que evoluiu posteriormente com quadro de diabetes insípido.

Índice glucémico y carga glucémica: su valor en el tratamiento y la prevención de las enfermedades crónicas no transmisibles / Glycemic index and glycemic load: their value in treatment and prevention of noncommunicable chronic diseases

Introducción: el patrón alimentario condiciona la prevención y control de enfermedades crónicas no trasmisibles (ECNT) de creciente prevalencia: obesidad, sobrepeso, insulinoresistencia, cáncer y enfermedades cardiovasculares (ECV). Cantidad y calidad de carbohidratos (CHO) afectan niveles de insulinemia y glucemia postprandiales, desencadenantes de mecanismos fisiopatológicos involucrados en ECNT. El Índice Glucémico (IG), una herramienta para clasificar alimentos según tipo de CHO, junto con la Carga Glucémica (CG) que considera cantidad de CHO, para predecir sus efectos sobre la glucemia postprandial, se limitaron inicialmente a la dietoterapia en diabetes; hoy los conocimientos sobre los efectos de distintos CHO en las ECNT ampliaron su uso a la población general como herramientas para seleccionar alimentos. Existe consenso creciente sobre sus beneficios en prevención de ECNT; considerando limitaciones: no contemplar respuesta insulínica, variación intra e interindividual en respuesta glucémica (RG) y dificultad para estimar IG en comidas mixtas. Aun así, se sostiene que, para realizar elecciones alimentarias saludables, interesa considerar composición química y efectos fisiológicos de los CHO, porque, por sí sola, la naturaleza química de los CHO alimentarios no describe sus efectos fisiológicos. Objetivos: realizar una puesta al día sobre la valoración que la comunidad científica internacional otorga a IG y CG, y su utilidad en el manejo de las ECNT.

Conclusión: El IG y la CG son considerados actualmente indicadores de gran valor para categorizar la calidad y cantidad de CHO alimentarios, dado que se reconocen sus efectos asociados en distintas magnitudes al riesgo de obesidad, ECV y cáncer. Además de sus usos educativos para estimular hábitos saludables, son frecuentes sus empleos epidemiológicos, permitiendo distinguir entre alimentos con alta y baja RG, identificando patrones alimentarios poblacionales. La escasez de datos respecto al IG en preparaciones típicas de los patrones alimentarios nacionales y regionales promueve la necesidad de desarrollar investigaciones locales en la temática.

Traumatic cerebrospinal fluid leakage following septorhinoplasty

Septoplasty/septorhinoplasty is a common ear, nose and throat procedure offered for those patients with deviated septum who are suffering from nasal obstruction and functional or cosmetic problems. Although it is a basic and simple procedure, it could lead to catastrophic complications including major skull base injuries which result in cerebrospinal fluid (CSF) leaks. We describe two different cases of traumatic CSF leaks following septoplasty/septorhinoplasty at two different sites. The first patient suffered a CSF leak following septoplasty and presented to Alexandria University Hospital. The leak was still active at presentation and identified as coming from a defect in the roof of the sphenoid sinus and was repaired surgically. The second patient presented 4 days after her cosmetic septorhinoplasty with a CSF leak and significant pneumocephalus. She was managed conservatively. Understanding the anatomical variations of the paranasal sinuses and implementing proper surgical techniques are crucial in preventing intracranial complications when performing either septoplasty or septorhinoplasty. A good quality computed tomography of the nose and paranasal sinuses is a valuable investigation to avoid major complications especially CSF leaks following either procedure.

Primary Polydipsia in Children: Two Case Reports

Primary polydipsia (PP) is marked by an increase in thirst, and most often presents in patients with psychiatric illnesses. Although uncommon in children, we experienced cases of PP in a 15-month-old boy and a 5-year-old girl. Both were admitted to the hospital with symptoms of polydipsia and polyuria that appeared 1–3 months before admission. Brain magnetic resonance imaging in both patients was normal. A water restriction test was performed after hospitalization and showed normal results. The symptoms improved after the parents were instructed to implement water-intake restriction for 2 weeks. Our report provides useful information for the treatment of PP in children.

Desmopressina oral para o tratamento de diabetes insípido central / Oral desmopressin for the treatment of central diabetes insipidus

A DOENÇA: O diabetes insípido é uma síndrome caracterizada pela incapacidade de concentração do filtrado urinário, com consequente desenvolvimento de urina hipotônica e aumento de volume urinário (1). Pode ocorrer por deficiência do hormônio antidiurético (ADH) [também conhecido como arginina vasopressina (AVP)] ou por resistência à sua ação nos túbulos renais. Quando há deficiência na síntese do ADH, o diabetes insípido é chamado central, neurohipofisário ou neurogênico (DIC); quando há resistência à sua ação nos túbulos renais, é dito renal ou nefrogênico. É uma doença rara que pode afetar todas as faixas etárias. A TECNOLOGIA: A desmopressina é um análogo sintético do ADH com maior tempo de ação, maior potência antidiurética e menor efeito pressórico quando comparado ao ADH. O tratamento do diabetes insípido com desmopressina tem embasamento em séries de casos. O primeiro relato de seu uso no tratamento de diabetes insípido central envolveu uma série de 10 pacientes com a condição. Nesse estudo, que utilizou como controles os dados históricos dos 10 pacientes no período em que usavam o ADH como tratamento, a desmopressina mostrou-se segura e apresentou vantagens em relação ao ADH, principalmente quanto ao número de aplicações do medicamento (6-10 doses/dia com ADH e 1-3 doses/dia com desmopressina) e aos efeitos adversos (comuns com ADH e não detectados com desmopressina). Pela inequívoca demonstração de tratar-se de um fármaco com perfil de segurança e efetividade favoráveis, a desmopressina no tratamento do diabetes insípido central foi amplamente adotada, não existindo ensaios clínicos randomizados comparando ADH e desmopressina no tratamento da condição. CONSIDERAÇÕES: Solicita-se a incorporação no PCDT de diabetes insípido da apresentação na forma comprimidos para o uso oral da desmopressina para propiciar mais uma opção de via de administração no tratamento dos pacientes com diabetes insípido. DELIBERAÇÃO FINAL: Os membros da CONITEC presentes na reunião do plenário do dia 03/08/2017 deliberaram, por unanimidade, por recomendar a incorporação de desmopressina oral para diabetes insípido desde que o custo de tratamento não seja superior à desmopressina já disponível no SUS. DECISÃO: PORTARIA Nº 61, DE 19 DE DEZEMBRO DE 2017. Torna pública a decisão de incorporar a desmopressina oral para Diabetes Insípido, mediante negociação de preço, no âmbito do Sistema Único de Saúde ­ SUS.

Diabetes insípida como primera manifestación de metástasis hipofisaria / Insipid diabetes as first sign of pituitary metastasis

Introducción: Diabetes insipidus as the first clinical manifestation of pituitary neoplasm metastasis Up to de 90 percent of the masses that are detected in the pituitary gland correspond to adenomas. On the contrary, pituitary metastasis only represent a 1 percent, which is a diagnostic challenge in the medical practice. Most of the time, these lesions are detected casually in autopsy; but it is important to consider that aproximatelly a 7 percent of these lesions can be clinically expresed as diabetes insipidus. Here we present a patient with initial symptoms of diabetes insipidus with the final diagnostic of lung adenocarcinoma

Infundibuloneurohipofisitis: caso clínico y revisión de la literatura / Infundibuloneurohypophysitis: clinical report and literature review

Infundibuloneurohypophysitis is a rare condition, which is part of the group of hypophysitis, of relatively recent description (1993). The main clinical manifestation is diabetes insipidus, whose natural evolution is towards chronicity. The differential diagnosis with other thickening of the hypophysial stem is very important, where the clinic, imaging, laboratory and eventually biopsy are a main support for a correct diagnosis. We present a clinical case that shows the usual picture of infundibuloneurohypophysitis, and illustrates the imaging evolution in a female patient, with diabetes insipidus as the main clinical manifestation

Diabetes mellitus vs diabetes insípida y un factor común: la poliuria. Presentación de un caso / Diabetes mellitus versus diabetes insipidus and a common factor: polyuria. Case presentation

La diabetes mellitus es una enfermedad crónica no trasmisible muy frecuente en la ciudad de Matanzas, se presenta en cualquier grupo etáreo, siendo tipo I o tipo II. En la diabetes tipo I, el cuerpo no produce insulina. En la diabetes tipo II, la más común, el cuerpo no produce o no usa la insulina adecuadamente. Sin suficiente insulina, la glucosa permanece en la sangre, provocando múltiples complicaciones tanto agudas como crónicas. La diabetes insípida es un trastorno poco común del metabolismo del agua. Esto quiere decir que el balance entre la cantidad de agua o líquido que usted toma no corresponde con el volumen de excreción urinaria. Es causada por una falta de respuesta o una respuesta deficiente a la hormona antidiurética vasopresina. Esta hormona controla el balance hídrico mediante la concentración de orina. Los pacientes con diabetes insípida orinan mucho, por lo cual necesitan beber bastantes líquidos para reemplazar los que pierden. Se presenta un paciente de 45 años con antecedentes de salud que debutó con una diabetes insípida y un año más tarde con una diabetes mellitus tipo II concomitando ambas, corroborándose por los complementarios correspondientes y mejorando con tratamiento (AU).

Diabetes mellitus is a non-transmissible chronic disease, very frequent in the city of Matanzas, which is present in any age group, and is classified as type I and type II. In the type I diabetes, the body does not produce insulin. In the type II diabetes, the most common one, the body does not produce or does not use it effectively. Without enough insulin, glucose remains in the blood, causing several complications, both acute and chronic. The diabetes insipidus is a few common disorder of the water metabolism. That means that the balance between the quantity of water or any other fluid someone drinks does not coincide with the volume of the urinary excretion. It is due to a lack of answer or a deficient answer to the anti-diuretic hormone vasopressin. This hormone controls the water balance through the urine concentration. The patients with diabetes insipidus urinate a lot, so they need to drink many liquids to replace those they lose. It is presented the case of a patient aged 45 years, with health antecedents, that debuted with diabetes insipidus and a year later with a concomitant type II diabetes mellitus. The complementary tests confirmed that and the patient got better with the treatment (AU).
