RESUMEN
Introducción: la hiperplasia suprarrenal congénita (HSC) comprende un conjunto de enfermedades hereditarias que involucran alteraciones en el ciclo del cortisol a nivel enzimático. La forma clásica tiene una incidencia de 1:14.000 a 1:18.000 nacimientos, mientras que la no clásica se presenta en 1:2.000 recién nacidos. Según la enzima involucrada, las manifestaciones clínicas varían desde asintomáticas a alteraciones en medio interno que comprometen la vida, por lo que debe tenerse un alto nivel de sospecha clínica para diagnosticarla en forma oportuna. En Uruguay, desde el año 2007, se cuenta con el pesquisaje de la 17-OH progesterona, producto aumentado en la forma más frecuente de HSC. El diagnóstico prenatal mediante la búsqueda de mutaciones en el gen CYP21A2, a través de punción de vellosidades coriales o amniocentesis, o del ADN fetal en sangre materna se recomienda en HSC con ambos padres portadores de la mutación severa y el antecedente de un hijo previo con la forma clásica. El tratamiento prenatal se considera en etapa experimental, con dexametasona en fetos femeninos con riesgo de enfermedad clásica, manteniéndose con la confirmación hasta el parto. Se presenta el caso clínico de una recién nacida de 11 días con HSC perdedora de sal y virilización de genitales externos, diagnosticada por la pesquisa neonatal. Se reporta su manejo interdisciplinario y evolución. Conclusiones: la hiperplasia suprarrenal es una enfermedad hereditaria potencialmente grave. La pesquisa neonatal constituye una herramienta efectiva para la detección de esta enfermedad. El manejo multidisciplinario es clave para el seguimiento y la optimización del tratamiento.
Introduction: congenital adrenal hyperplasia (CAH) involves a set of hereditary diseases that include alterations in the cortisol cycle, at enzymatic level. The classic variant has an incidence of 1:14,000 to 1:18,000 births, while the non-classic one occurs in 1:2,000 newborns. As a result of the enzyme involved, the clinical manifestations change from asymptomatic to alterations in the internal environment that compromise life, so clinical suspicion must be high in order to diagnose it in a timely manner. The diagnosis is more frequently made by neonatal screening than by physical examination, and it is a more sensitive method, especially in males, since there are no changes at the level of external genitalia. The implementation of screening has reduced the time prior to diagnosis. In Uruguay, since 2007, a universal screening has been carried out measuring 17-OH progesterone, which is increased in the most frequent form of CAH. Treatment is lifelong, consisting of oral glucocorticoids (hydrocortisone) and mineralocorticoids (fludrocortisone). We recommend prenatal diagnosis by searching for mutations in the CYP21A2 gene through chorionic villus puncture or amniocentesis, or fetal DNA in maternal blood in cases of CAH if both parents are carriers of the severe mutation and have a history of a previous classic case. Prenatal treatment with dexamethasone is considered in the experimental stage, in female fetuses at risk of the standard disease, which is maintained until birth if confirmed. We present a clinical case of an 11-day-old newborn with salt-wasting congenital adrenal hyperplasia and virilization of the external genitalia, diagnosed by neonatal screening. We report her management and interdisciplinary evolution. Conclusion: adrenal hyperplasia is a potentially serious inherited disease. Neonatal screening is an effective tool for detecting this disease. Multidisciplinary management is key to monitoring and optimizing treatment.
Introdução: a hiperplasia adrenal congênita (HAC) compreende um conjunto de doenças hereditárias que envolvem alterações no ciclo do cortisol, em nível enzimático. A forma clássica tem incidência de 1:14.000 a 1:18.000 nascimentos, enquanto a forma não clássica ocorre em 1:2.000 recém-nascidos. Dependendo da enzima envolvida, as manifestações clínicas variam de assintomáticas até alterações do ambiente interno que comprometem a vida, portanto é necessário ter um alto nível de suspeita clínica para diagnosticá-la em forma precoce. No Uruguai, desde 2007, existe triagem para 17-OH progesterona, produto aumentado na forma mais frequente de HAC. O diagnóstico pré-natal pela busca de mutações no gene CYP21A2 por meio de punção de vilosidades coriônicas ou amniocentese, ou DNA fetal no sangue materno é recomendado na HAC com ambos os pais portadores da mutação grave e história de filho anterior com a forma clássica. O tratamento pré-natal é considerado em fase experimental, com dexametasona em fetos femininos com risco de doença clássica, continuando com confirmação até o parto. É apresentado o caso clínico de um recém-nascido de 11 dias com hiperplasia adrenal congênita perdedora de sal e virilização da genitália externa, diagnosticado por triagem neonatal. Relatamos sua gestão interdisciplinar e evolução. Conclusões: a hiperplasia adrenal é uma doença hereditária potencialmente grave. A triagem neonatal é uma ferramenta eficaz para detectar esta doença. O manejo multidisciplinar é fundamental para monitorar e otimizar o tratamento.

ABSTRACT Objective: The main objective of this study was to compare stress and anxiety levels in children undergoing surgical procedures with or without parental presence at induction of anesthesia by measuring salivary cortisol levels and applying the mYPAS. Method: Quasi-randomized trial with children aged 5-12 year, with ASA physical status I, II, or III, undergoing elective surgery. According to parents' willingness, the pair were defined as accompanied or unaccompanied group. Chi-square, Fisher's exact tests, Student's t test, Mann-Whitney, Hodges-Lehman and Spearman's tests were used for statistical analyzes. Results: We included 46 children; 63% were preschool children mostly accompanied by their mothers (80%). The median mYPAS score was 37.5 (quartile range, 23.4-51.6) in unaccompanied children, and 55.0 (quartile range, 27.9-65.0) in accompanied children, with an estimated median difference of +11.8 (95% CI of 0 to 23.4; p = 0.044). There were no significant differences in the mean salivary cortisol levels. Conclusion: The level of anxiety was higher in accompanied children. There were no differences in salivary cortisol levels between both groups. Brazilian Registry of Clinical Trials (ReBEC):RBR-9wj4qvy.

Introducción: La placenta sintetiza y secreta varias hormonas que permiten la regulación del embarazo, el trabajo de parto y la adaptación metabólica materno-fetal. Su comportamiento asociado al tipo de parto puede dar información relevante sobre efectos epigenéticos. Objetivo: Describir el tipo de parto con los niveles de oxitocina, cortisol y hormonas tiroideas en plasma de cordón umbilical al nacer. Método: A 50 mujeres con embarazos principalmente normales se les cuantificaron los niveles neurohormonales en plasma de cordón umbilical, obtenido inmediatamente tras el periodo expulsivo. Los resultados se incorporaron a la base de datos clínicos de cada participante y se analizaron con Stata v.14.0. El protocolo fue aprobado por el comité de ética. Resultados: Hubo 33 partos vaginales (12 espontáneos, 13 acelerados y 8 inducidos) y 17 cesáreas (7 electivas y 10 de urgencia). Se observaron mayores niveles de cortisol en los partos vaginales acelerados; las cesáreas tuvieron menores niveles de cortisol y hormona estimulante de la tiroides. Las intervenciones clínicas, con altos o bajos niveles hormonales, están en directa relación con el tipo de parto. Conclusiones: El cortisol y la hormona estimulante de la tiroides medidos en plasma de cordón umbilical variaron según el tipo de parto. Esto es una primera cuantificación de hormonas en plasma de cordón umbilical y su posible regulación placentaria a propósito del tipo de parto.
Introduction: The placenta synthesizes and secretes several hormones allowing the regulation of pregnancy, labor and maternal-fetal metabolic adaptation. Their behavior associated with the type of delivery, may provide relevant information on epigenetic effects. Objective: To describe the type of delivery with the levels of oxytocin, cortisol and thyroid hormones in umbilical cord plasma at birth. Method: Neurohormonal levels from umbilical cord plasma obtained immediately post expulsion, were quantified in 50 women with mainly normal pregnancies. Results incorporated into the clinical database of each participant, statistically analyzed in Stata v.14.0. Protocol approved by ethics committee. Results: 33 were vaginal deliveries (12 spontaneous, 13 accelerated, 8 induced) and 17 cesarean sections (7 elective and 10 emergency). Higher cortisol levels were observed in accelerated vaginal deliveries, cesarean sections had lower cortisol and thyroid stimulating hormone levels. While clinical interventions, with high or low hormone levels, were related to the type of delivery. Conclusions: Cortisol and thyroid stimulating hormone measured in umbilical cord plasma varied according to the type of delivery. This is a first quantification of hormones in umbilical cord plasma and their possible placental regulation in relation to the type of delivery.

OBJECTIVE@#To investigate the coagulation function indicators and identify influence factors of hypercoagulability in patients with adrenocorticotropic hormone (ACTH) independent Cushing syndrome (CS).@*METHODS@#In our retrospective study, the electronic medical records system of Peking University First Hospital was searched for the patients diagnosed with ACTH independent CS on discharge from January 2014 to June 2019. Nonfunctional adrenal adenoma patients were chosen as control group and matched 1 ∶1 by body mass index (BMI), gender, and discharge date. Clinical features and coagulation function indicators were compared between the two groups.@*RESULTS@#In the study, 171 patients were included in each group. Compared with control group, activated partial thromboplastin time (APTT), and prothrombin time (PT) in ACTH independent CS group were significantly lower [(29.22±3.39) s vs. (31.86±3.63) s, P < 0.001; (29.22±3.39) s vs. (31.86±3.63) s, P < 0.001], and both D-dimer and fibrin degradation products (FDP) levels were significantly higher (P < 0.05). Percentage of APTT levels under the lower limit of reference range in the CS patients was significantly higher than that in nonfunctional group (21.6% vs. 3.5%, P < 0.001). Percentage of D-dimer levels over the upper limit of reference range in the CS patients was significantly higher than that in nonfunctional group (13.5% vs. 6.6%, P=0.041). There were three patients with deep venous thrombosis and one patient with pulmonary embolism in CS group, however none was in control group. The area under curve (AUC) of serum cortisol rhythm (8:00, 16:00 and 24:00) levels was negatively associated with the levels of PT (r=-0.315, P < 0.001) and APTT (r=-0.410, P < 0.001), and positively associated with FDP (r=0.303, P < 0.001) and D-dimer levels (r=0.258, P < 0.001). There were no differences in coagulation function indicators among different histopathologic subgroups (adrenocortical adenoma, adrenocortical hyperplasia, oncocytic adenoma, adrenocortical carcinoma). With Logistic regression analysis, the AUC of cortisol and glycosylated hemoglobin A1c (HbA1c) levels were independent risk factors for hypercoagulability in the ACTH independent CS patients (P < 0.05).@*CONCLUSION@#ACTH independent CS patients were more likely in hypercoagulable state compared with nonfunctional adrenal adenoma, especially in ACTH independent CS patients with higher levels of cortisol AUC and HbA1c. These patients should be paid attention to for the hypercoagulability and thrombosis risk.

Objectives@#This study determined the baseline hormonal levels of the hypothalamic-pituitary-adrenal axis and their associated factors in noncritically ill hospitalized patients with coronavirus disease 2019 (COVID-19).@*Methodology@#This cross-sectional observational study was carried out in 91 noncritical RT-PCR-confirmed COVID-19 patients (18-65 years) recruited consecutively from the COVID unit, of two tertiary care hospitals over a period of six months. After screening for exclusion criteria relevant history and physical examinations were done, and blood was drawn between 07:00 am to 09:00 am in a fasting state to measure serum cortisol and plasma adrenocorticotropic hormone (ACTH) by chemiluminescent microparticle immunoassay.@*Result@#Of 91 patients, 54, 26, and 11 had mild, moderate, and severe disease respectively. Median values of serum cortisol (p=0.057) and plasma ACTH (p=0.910) were statistically similar among the severity groups. Considering cortisol cut-off of 276 nmol/L (<10 μg/dL), the highest percent of adrenal insufficiency was present in severe (27.3%), followed by mild (25.9%) and least in moderate (3.8%) COVID-19 cases. Using the cortisol/ACTH ratio >15, only 6.6% had enough reserve.@*Conclusions@#The adrenocortical response was compromised in a significant percentage of noncritically ill hospitalized patients with COVID-19, which is unrelated to infection severity, with greater percentages present in severely infected cases.

Objective: To explore the value of catheter-based adrenal ablation in treating Cushing's syndrome (CS)-associated hypertension. Methods: A clinical study was conducted in patients with CS, who received catheter-based adrenal ablation between March 2018 and July 2023 in Daping Hospital. Parameters monitored were blood pressure (outpatient and 24-hour ambulatory), body weight, clinical characteristics, serum cortisol and adrenocorticotropic hormone (ACTH) at 8 am, 24-hour urinary free cortisol (24 h UFC), fasting blood glucose and postoperative complications. Procedure effectiveness was defined as blood pressure returning to normal levels (systolic blood pressure<140 mmHg (1 mmHg=0.133 kPa) and diastolic blood pressure<90 mmHg), cortisol and 24 h UFC returning to normal and improvement of clinical characteristics. The parameters were monitored during follow up in the outpatient department at 1, 3, 6, and 12 months after catheter-based adrenal ablation. Results: A total of 12 patients (aged (40.0±13.2) years) were reviewed. There were 5 males, with 5 cases of adenoma and 7 with hyperplasia from imaging studies. Catheter-based adrenal ablation was successful in all without interruption or surgical conversion. No postoperative complication including bleeding, puncture site infection, adrenal artery rupture or adrenal bleeding was observed. The mean follow up was 28 months. Compared to baseline values, body weight declined to (59.48±11.65) kg from (64.81±10.75) kg (P=0.008), fasting blood glucose declined to (4.54±0.83) mmol from (5.53±0.99) mmol (P=0.044), outpatient systolic blood pressure declined to (128±21) mmHg from (140±19) mmHg (P=0.005), diastolic blood pressure declined to (78±10) mmHg from (86±11) mmHg (P=0.041), and the mean ambulatory daytime diastolic blood pressure declined to (79±12) mmHg from (89±8) mmHg (P=0.034). Catheter-based adrenal ablation in 8 patients was defined as effective with their 24 h UFC significantly reduced after the procedure (1 338.41±448.06) mmol/L from (633.66±315.94) mmol/L, P=0.011). The change of 24 h UFC between the effective treatment group and ineffective group was statistically significant (P=0.020). The postoperative systolic blood pressure in the treated adenoma group was significantly lower than those of hyperplasia group (112±13) mmHg vs. (139±20) mmHg, P=0.026). Conclusions: For patients with CS-associated hypertension who are unwilling or unable to undergo surgical treatment, catheter-based adrenal ablation could improve the blood pressure and cortisol level. Catheter-based adrenal ablation could be a safe, effective, and minimally invasive therapy. However, our results still need to be validated in further large-scale studies.

Introducción: La insuficiencia adrenal hipotálamo hipofisaria usualmente se manifiesta secundaria a tumores y, cuando resulta congénita se asocia, con frecuencia, con otras deficiencias hormonales. La crisis adrenal suele presentarse en su debut y puede resultar potencialmente mortal. Objetivo: Examinar el caso de una paciente con insuficiencia adrenal central que debutó con una crisis adrenal congénita. Presentación del caso: Recién nacida a término, padres no consanguíneos, hospitalizada a los 9 días de vida por clínica de una semana con múltiples episodios eméticos y apnea. Ingresó con deshidratación severa, hipotensa y estuporosa. Además, se encontró acidosis metabólica severa, hipoglucemia persistente, hiponatremia e insuficiencia prerrenal. Ante la no mejoría de su estado hemodinámico, a pesar del uso de cristaloides y vasopresores, finalmente mejoró con la administración de dosis altas de hidrocortisona. El diagnóstico de deficiencia de cortisol de origen central se realizó con un test dinámico de insulina y la resonancia magnética nuclear hipofisaria. Conclusiones: La crisis adrenal se debe tener presente como diagnóstico diferencial en episodios agudos con inestabilidad hemodinámica persistente e hipoglucemia de difícil manejo. Adicionalmente, hay que considerar que existen otras causas menos comunes de insuficiencia adrenal en neonatos como la hipoplasia hipofisaria(AU)
Introduction: Hypothalamic-pituitary adrenal insufficiency usually manifests secondary to tumors and, when congenital, is often associated with other hormonal deficiencies. Adrenal crisis usually occurs at its onset and can be life threatening. Objective: To review the case of a patient with central adrenal insufficiency who had an onset with a congenital adrenal crisis. Case presentation: Term newborn, non-consanguineous parents, hospitalized at 9 days of life for a week-long clinical presentation with multiple emetic episodes and apnea. She was admitted with severe dehydration, hypotensive and stuporous. In addition, severe metabolic acidosis, persistent hypoglycemia, hyponatremia and prerenal failure were found. Given the lack of improvement of her hemodynamic status, despite the use of crystalloids and vasopressors, she finally improved with the administration of high doses of hydrocortisone. The diagnosis of cortisol deficiency of central origin was made with a dynamic insulin test and pituitary nuclear magnetic resonance imaging. Conclusions: Adrenal crisis should be kept in mind as a differential diagnosis in acute episodes with persistent hemodynamic instability and difficult-to-manage hypoglycemia. Additionally, other less common causes of adrenal insufficiency in neonates, such as pituitary hypoplasia, should be considered(AU)

Introducción: La relación entre producción de leche materna y la música ha sido reportada en diversas publicaciones científicas. No hay publicaciones en Uruguay que analicen esta relación. Este estudio fue realizado por el Instituto Universitario CEDIIAP junto a la Universidad ORT, el Banco de Leche Humana del Hospital Pereira Rossell (CHPR), de la Administración de los Servicios de Salud del Estado. Fue aprobado por el Comité de Ética del CHPR. Objetivo: evidenciar la relación entre el estímulo musical y la producción de leche de madres de recién nacidos pretérmino internados en Cuidados Intensivos del CHPR. Material y métodos: estudio cuasiexperimental, de corte longitudinal, prospectivo, diseño doble: intervención antes después y en paralelo (un grupo contra el otro) utilizando audición de canciones elegidas por las madres con andamiento modificado. Criterios de inclusión: cohorte de madres de recién nacidos ≤ 34 semanas de gestación, sin alimentación a pecho directo, medicación psiquiátrica o que afectara la producción de leche. Se analizó cortisol en saliva y volumen de leche. Como análisis multivariado final, se aplicó el modelo lineal general de medidas repetitivas. Resultados: el estudio se realizó entre marzo de 2017 y agosto de 2018 con 31 madres (15 intervención, 16 control). El grupo intervención presentó mayor producción láctea en los 2 primeros días y disminución del 57 % en niveles de cortisol frente al grupo control. Conclusiones: más allá de las limitaciones del trabajo, los resultados apuntan a que la musicoterapia podría colaborar en la disminución del estrés, el disfrute de la lactancia materna y, consecuentemente, en una mayor producción de leche.
Introduction: the relationship between breast milk production and music has been previously reported in several peer reviewed journals. There are no studies in Uruguay analyzing this relationship. The present study was performed by the CEDIIAP University Institute jointly with the ORT University, at the Pereira Rossell Hospital Human Milk Bank (CHPR) of the Administration of State Health Services (ASSE) in Montevideo. It has been approved by the CHPR's Ethics Committee. Objective: demonstrate the influence of musical stimulation on milk production of mothers with preterm newborns admitted in the CHPR Neonatology Intensive Care Unit. Material and Methods: longitudinal, prospective experimental study with double design: intervention before, simultaneous (one group against the other) and after the study. We used the music therapy technique of listening to songs chosen by the mothers and modified gait. Milk volume was quan- tified, and cortisol presence was analyzed in saliva. The General Linear Model of repetitive measures was applied. Inclusion criteria: cohort of mothers of newborns ≤ 34 weeks of gestation, without direct breastfeeding, psychiatric medication or affecting milk production. Saliva cortisol levels and milk volume were analyzed. As a final multivariate analysis, the General Linear Model of repetitive measures was applied. Results: the study was carried out from March 2017 till August 2018 with a total of 31 mothers (15 intervention, 16 control). Higher milk production in the first two days and a decrease of 57% in cortisol levels were observed in the intervention group compared to the control group. Conclusions: in spite of the limitations of this paper, our results suggest that music therapy can help to reduce the stress and increase the enjoyment of breastfeeding and consequently generate a higher milk production.
Introducion: a relação entre produção do leite materno e a música foi apontada com evidências científicas em vários jornais. Não existem publicações no Uruguai que analisem esta relação. Este estudo foi realizado pelo Instituto universitário CEDIIAP junto com a Universidade ORT, o Banco de Leite Humano do Hospital Pereira Rossell (CHPR) da Administração dos Serviços de Saúde do Estado. Foi aprovado pelo Comité de Ética do CHPR. Objetivo: evidenciar a relação entre o estímulo musical e a produção do leite de mães com recém nascidos prematuros internados na unidade de cuidados intensivos do CHPR. Material e metodo: estudo quase experimental de corte longitudinal, prospectivo com desenho duplo: intervenção antes, depois e em paralelo (um grupo contra o outro) utilizando a audição de canções escolhidas pelas mães e andamento modificado. Critérios de inclusão: coorte de mães de recém nascidos ≤ 34 semanas de gestação sem alimentação a peito direto, nem medicação psiquiátrica ou que afetara a produção de leite. Foi analisado o cortisol em saliva e o volumem de leite. Aplicouse o Modelo Linear General de medidas repetitivas como análise multivariado final. Resultados: o estudo foi realizado entre março 2017 e agosto 2018 com 31 mães (15 do grupo intervenção, 16 do grupo controle). Foi observada maior produção láctea no grupo de intervenção nos dois primeiros dias e diminuição de 57% nos níveis de cortisol em relação ao grupo controle. Conclusões: além das limitações do paper, os resultados apontam para que a musicoterapia poderia colaborar na diminuição do estresse, o desfrute da lactância materna e consequentemente poderiam resultar em uma maior produção de leite.

ABSTRACT Introduction This paper studies physiological and biochemical indicators in the systematic training of sprinters. This paper analyzes the data measured during the athletes' training process and studies the detailed data of their physical functions. Objective This study aimed to find a link between exercise data and biochemical indicator data in sprinter athletes. By analyzing the data from this article, the researchers were able to find the optimal training program for the athletes. Methods High-intensity aerobic training tests were performed with statistical analysis of various physiological and biochemical indicators. Results Hemoglobin data were shown to be highly sensitive to intensity. The researchers found that long-term high-load training in athletes can lead to physical fatigue. This fatigue production is positively correlated with the intensity of the training load. Conclusion There is a strong positive correlation between biochemical and physiological indicators on performance levels in sprinter athletes. Evidence Level II; Therapeutic Studies - Investigating the results.

INTRODUCCIÓN. La crisis suprarrenal se refiere a la insuficiencia suprarrenal aguda; la cual es un trastorno en el que la corteza adrenal no produce suficientes hormonas esteroides (en especial cortisol) para satisfacer las demandas del cuerpo, de acuerdo al mecanismo fisiopatológico se la puede clasificar como primaria, secundaria y terciaria, siendo más común en pacientes con insuficiencia suprarrenal primaria. Es una emergencia potencialmente mortal que requiere tratamiento inmediato. OBJETIVO. Establecer una estrategia de prevención y tratamiento de la crisis suprarrenal, así como la farmacoterapia ideal y sus alternativas válidas. MATERIAL Y MÉTODOS. Se realizó una revisión bibliográfica en varias revistas virtuales de alto carácter científico como Cochrane Library, Cochrane Systematic Reviews Database, MEDLINE a través de PubMed y ClinicalTrial.gov. Se seleccionaron revisiones sistemáticas con o sin metaanálisis, ensayos clínicos y recomendaciones de expertos relacionados con prevención y tratamiento de crisis suprarrenal en general. RESULTADOS. Se obtuvieron 1819 resultados, de los cuales se seleccionaron 20 artículos con mayor validez y replicabilidad en el medio para establecer un protocolo unificado de actuación. CONCLUSIÓN. El objetivo de la terapia es el tratamiento de la hipotensión y reversión de las anomalías electrolíticas y de la deficiencia de cortisol. Se deben infundir por vía intravenosa grandes volúmenes (1 a 3 litros) de solución salina al 0,9% o dextrosa al 5% en solución salina al 0,9% y la administración de hidrocortisona (bolo de 100 mg), seguido de 50 mg cada 6 horas (o 200 mg / 24 horas como infusión continua durante las primeras 24 horas). Si no se dispone de hidrocortisona, las alternativas incluyen prednisolona, prednisona y dexametasona.
INTRODUCTION. Adrenal crisis refers to acute adrenal insufficiency; which is a disorder in which the adrenal cortex does not produce enough steroid hormones (especially cortisol) to meet the body's demands, according to the pathophysiological mechanism it can be classified as primary, secondary and tertiary, being more common in patients with primary adrenal insufficiency. It is a life-threatening emergency that requires immediate treatment. OBJECTIVE. To establish a strategy for the prevention and treatment of adrenal crisis, as well as the ideal pharmacotherapy and its valid alternatives. MATERIAL AND METHODS. A literature review was performed in several highly scientific virtual journals such as Cochrane Library, Cochrane Systematic Reviews Database, MEDLINE through PubMed and ClinicalTrial.gov. Systematic reviews with or without meta-analysis, clinical trials and expert recommendations related to prevention and treatment of adrenal crisis in general were selected. RESULTS. A total of 1819 results were obtained, from which 20 articles with greater validity and replicability in the setting were selected to establish a unified protocol for action. CONCLUSIONS. The aim of therapy is the treatment of hypotension and reversal of electrolyte abnormalities and cortisol deficiency. Large volumes (1 to 3 liters) of 0.9% saline or 5% dextrose in 0.9% saline and administration of hydrocortisone (100 mg bolus), followed by 50 mg every 6 hours (or 200 mg / 24 hours as a continuous infusion for the first 24 hours) should be infused intravenously. If hydrocortisone is not available, alternatives include prednisolone, prednisone, and dexamethasone.

ABSTRACT BACKGROUND: Use of inhaled corticosteroids for managing acute asthma exacerbations has been tested since the 1990s. OBJECTIVE: To compare high doses of inhaled ciclesonide with systemic hydrocortisone for managing acute asthma exacerbations in the emergency department. DESIGN AND SETTING: Double-blind, randomized clinical trial in the public healthcare system of the city of São Paulo. METHODS: Fifty-eight patients with moderate or severe asthma with peak flow < 50% of predicted were randomized into two groups. Over the course of four hours, one group received 1440 mcg of inhaled ciclesonide plus hydrocortisone-identical placebo (ciclesonide + placebo), while the other received 500 mg of intravenous hydrocortisone plus ciclesonide-identical placebo (hydrocortisone + placebo). Both groups received short-acting bronchodilators (fenoterol hydrobromide and ipratropium bromide). The research protocol included spirometry, clinical evaluation, vital signs and electrocardiogram monitoring. Data were obtained at 30 (baseline), 60, 90, 120, 180, and 240 minutes. We compared data from baseline to hour 4, between and within groups. RESULTS: Overall, 31 patients received ciclesonide + placebo and 27 received hydrocortisone + placebo. Inhaled ciclesonide was as effective as intravenous hydrocortisone for improving clinical parameters (Borg-scored dyspnea, P = 0.95; sternocleidomastoid muscle use, P = 0.55; wheezing, P = 0.55; respiratory effort, P = 0.95); and spirometric parameters (forced vital capacity, P = 0.50; forced expiratory volume in the first second, P = 0.83; peak expiratory flow, P = 0.51). CONCLUSIONS: Inhaled ciclesonide was not inferior to systemic hydrocortisone for managing acute asthma exacerbations, and it improved both clinical and spirometric parameters.

Hyperadrenocorticism is a common endocrinopathy in dogs, associated to an excessive production or administration of cortisol.Aims:Report the evolution of homeopathic treatment in spontaneous hyperadrenocorticism analyzing with basal and post-acth stimulation cortisol values of a yorkshire male dog with 10 years old, diagnosed from the suppression test with low dose of dexamethasone and stimulation with ACTH, as well as complementary tests.Methodology: Homeopathic treatment was chosen, based on the principle of similitude usingIgnatia amarabecause the patient presents repertorized mental symptoms such as separation anxiety syndrome, docility, annoyances and jealousy and also because it is efficient and less harmful. It was associated to cortisol biotherapy to inhibit cortisol production and adrenal biotherapy to control the response of excess of the cortisol producted by the gland. The exposed information is consented by the tutor.Results:The dog was in convencional treatment with trilostane but didn't response to the therapy, showing 5,41 µg/dL of basal result and 11,8 µg/dL of post-acth result and the symptoms were worst on 12/12/2021, presenting lethargic, panting, more evident alopecia and severe muscle weakness which the patient unable to stand. Therefore, the protocol was recommended for 3 months, included 3 globules ofIgnatia amara30cH orally, every 12 hours, 3 globules of cortisol biotherapy 30 cH and also of adrenal biotherapy 6 cH every 24 hours. On 03/28/2022 the basal and post-acth stimulation results was 3,71 µg/dL e 5,79 µg/dL respectively and the patient was more active, the skin was better and even with difficulty it was movingand having more independence.Conclusion: Homeopathic treatment with high dilution was effective, keeping the indices with the recommended range of post acth between 2.0 and 5.0, confirming an adequate therapeutic monitoring and symptomatic improvement.

Aggression is an evolutionary behavior as it has a role in survival, increasing one's access to food, shelter, status and reproduction. Testosterone and Cortisol are hormones often linked to aggressive behavior. We gathered and organized data from the last five years on the relation among Testosterone, Cortisol and aggression, while assessing the methods used by those scientific papers. A systematic review was made according to PRISMA guidelines. The search for indexed articles was performed in January 2019 using the keywords aggress* AND Testosterone AND Cortisol in three databases: Web of Science, SCOPUS and PsycInfo. The specific role of Testosterone and Cortisol in aggressive behavior is not unanimous. However, most articles found either an increase in Testosterone or a decrease in Cortisol associated with this behavior. There is the need for standardizing methods of triggering and assessing aggressive behavior, taking into account the assessment of social desirability and its impacts.

A testosterona e o cortisol são hormônios frequentemente associados a comportamentos agressivos. Este estudo reúne e organiza dados dos últimos cinco anos sobre a relação entre testosterona, cortisol e agressividade, avaliando também os métodos utilizados pelos artigos. Uma revisão sistemática foi conduzida segundo as diretrizes do PRISMA. Uma pesquisa eletrônica de artigos foi realizada em janeiro de 2019, usando as palavras-chave agress* AND Testosterone AND Cortisol em três bancos de dados: Web of Science, SCOPUS e PsycInfo. O papel desses hormônios no comportamento agressivo não é unânime, porém a maioria dos artigos incluídos encontrou um aumento na testosterona ou uma diminuição no cortisol, associados a esse comportamento. Há a necessidade de padronizar os métodos de induzir e de avaliar agressividade, levando em conta a desejabilidade social e seus impactos.

Pituitary immune-related adverse events induced by programmed cell death protein 1 inhibitors in advanced lung cancer patients: A report of 3 cases SUMMARY Programmed cell death protein 1 (PD-1) and its ligand 1 (PD-L1) have been widely used in lung cancer treatment, but their immune-related adverse events (irAEs) require intensive attention. Pituitary irAEs, including hypophysitis and hypopituitarism, are commonly induced by cytotoxic T lymphocyte antigen 4 inhibitors, but rarely by PD-1/PD-L1 inhibitors. Isolated adrenocorticotropic hormone(ACTH) deficiency (IAD) is a special subtype of pituitary irAEs, without any other pituitary hormone dysfunction, and with no enlargement of pituitary gland, either. Here, we described three patients with advanced lung cancer who developed IAD and other irAEs, after PD-1 inhibitor treatment. Case 1 was a 68-year-old male diagnosed with metastatic lung adenocarcinoma with high expression of PD-L1. He was treated with pembrolizumab monotherapy, and developed immune-related hepatitis, which was cured by high-dose methylprednisolone [0.5-1.0 mg/(kg·d)]. Eleven months later, the patient was diagnosed with primary gastric adenocarcinoma, and was treated with apatinib, in addition to pembrolizumab. After 17 doses of pembrolizumab, he developed severe nausea and asthenia, when methylprednisolone had been stopped for 10 months. His blood tests showed severe hyponatremia (121 mmol/L, reference 137-147 mmol/L, the same below), low levels of 8:00 a.m. cortisol (< 1 μg/dL, reference 5-25 μg/dL, the same below) and ACTH (2.2 ng/L, reference 7.2-63.3 ng/L, the same below), and normal thyroid function, sex hormone and prolactin. Meanwhile, both his lung cancer and gastric cancer remained under good control. Case 2 was a 66-year-old male with metastatic lung adenocarcinoma, who was treated with a new PD-1 inhibitor, HX008, combined with chemotherapy (clinical trial number: CTR20202387). After 5 months of treatment (7 doses in total), his cancer exhibited partial response, but his nausea and vomiting suddenly exacerbated, with mild dyspnea and weakness in his lower limbs. His blood tests showed mild hyponatremia (135 mmol/L), low levels of 8:00 a.m. cortisol (4.3 μg/dL) and ACTH (1.5 ng/L), and normal thyroid function. His thoracic computed tomography revealed moderate immune-related pneumonitis simultaneously. Case 3 was a 63-year-old male with locally advanced squamous cell carcinoma. He was treated with first-line sintilimab combined with chemotherapy, which resulted in partial response, with mild immune-related rash. His cancer progressed after 5 cycles of treatment, and sintilimab was discontinued. Six months later, he developed asymptomatic hypoadrenocorticism, with low level of cortisol (1.5 μg/dL) at 8:00 a.m. and unresponsive ACTH (8.0 ng/L). After being rechallenged with another PD-1 inhibitor, teslelizumab, combined with chemotherapy, he had pulmonary infection, persistent low-grade fever, moderate asthenia, and severe hyponatremia (116 mmol/L). Meanwhile, his blood levels of 8:00 a.m. cortisol and ACTH were 3.1 μg/dL and 7.2 ng/L, respectively, with normal thyroid function, sex hormone and prolactin. All of the three patients had no headache or visual disturbance. Their pituitary magnetic resonance image showed no pituitary enlargement or stalk thickening, and no dynamic changes. They were all on hormone replacement therapy (HRT) with prednisone (2.5-5.0 mg/d), and resumed the PD-1 inhibitor treatment when symptoms relieved. In particular, Case 2 started with high-dose prednisone [1 mg/(kg·d)] because of simultaneous immune-related pneumonitis, and then tapered it to the HRT dose. His cortisol and ACTH levels returned to and stayed normal. However, the other two patients' hypopituitarism did not recover. In summary, these cases demonstrated that the pituitary irAEs induced by PD-1 inhibitors could present as IAD, with a large time span of onset, non-specific clinical presentation, and different recovery patterns. Clinicians should monitor patients' pituitary hormone regularly, during and at least 6 months after PD-1 inhibitor treatment, especially in patients with good oncological response to the treatment.

OBJECTIVES@#To study the effect of somatostatin on postoperative gastrointestinal function and stress level in children with acute abdomen.@*METHODS@#A total of 102 children with acute abdomen who underwent surgery in Xuzhou Children's Hospital from August 2019 to June 2021 were enrolled as subjects and were randomly divided into an observation group and a control group, with 51 children in each group. The children in the control group were given conventional treatment such as hemostasis and anti-infective therapy after surgery, and those in the observation group were given somatostatin in addition to conventional treatment. Peripheral blood samples were collected from both groups before surgery and on days 1 and 5 after surgery. The two groups were compared in terms of the serum levels of endothelin-1 (ET-1), adrenocorticotropic hormone (ACTH), cortisol, gastrin, and motilin, postoperative recovery, and the incidence rate of complications.@*RESULTS@#There was no significant difference in the serum levels of ET-1, ACTH, cortisol, gastrin, and motilin between the two groups before surgery (P>0.05). Compared with the control group, the observation group had significantly lower serum levels of ET-1, ACTH, and cortisol on days 1 and 5 after surgery (P<0.05) and significantly higher levels of motilin and gastrin on day 5 after surgery (P<0.05). Compared with the control group, the observation group had significantly shorter time to first passage of flatus, first bowel sounds, and first defecation after surgery, as well as a significantly shorter length of hospital stay (P<0.05). The incidence rate of complications in the observation group was significantly lower than that in the control group (6% vs 24%, P<0.05).@*CONCLUSIONS@#In children with acute abdomen, somatostatin can significantly reduce postoperative stress response, improve gastrointestinal function, and reduce the incidence rate of complications, thereby helping to achieve a good prognosis.

OBJECTIVES@#To explore the damage effects of chronic restraint stress (CRS) on amygdala cells through the rat CRS model.@*METHODS@#The rat CRS model was established, and the changes in body weight and adrenal mass in control group and CRS group were monitored at 1 d, 7 d, 14 d and 21 d. The behavior changes were evaluated by the percentage of retention time of open arms and open arm entries using the elevated plus maze (EPM). ELISA was used to detect the concentrations of rat's corticotropin releasing hormone (CRH), adrenocorticotropic hormone (ACTH) and cortisol. The changes of expression of glucocorticoid receptor (GR) and glial fibrillary acidic protein (GFAP) in amygdala were determined by immunohistochemistry and Western blotting. Ultrastructure changes of glial cell were observed by transmission electron microscopy. The apoptosis rate of amygdala was measured by flow cytometry.@*RESULTS@#Compared with the control group at the same time points, body weight of CRS 1 d, 7 d, 14 d and 21 d groups increased slowly, but adrenal mass increased significantly; the serum level of CRH, cortisol and ACTH increased significantly at 7 d, 14 d and 21 d respectively; the expression of GR in amygdala was increased while that of GFAP was decreased; EPM test suggested that the percentage of retention time of open arms and open arm entries decreased significantly after 14 d. The CRS group showed different degrees of glial cell damage in amygdala, and the apoptosis rate of glial cell was significantly increased in 21 d group.@*CONCLUSIONS@#This study successfully established a CRS model in rats, and anxiety-like behavioral changes in model rats may be caused by apoptosis of amygdala astrocytes.
