1. Central adrenal insufficiency: who, when, and how? From the evidence to the controversies – an exploratory review
ABSTRACT Central adrenal insufficiency (CAI) is a life-threatening disorder. This occurs when ACTH production is insufficient, leading to low cortisol levels. Since corticosteroids are crucial to many metabolic responses under organic stress and inflammatory conditions, CAI recognition and prompt treatment are vital. However, the diagnosis of CAI is challeng

2. ARMC5 mutations are associated with high levels of proliferating cell nuclear antigen and the presence of the serotonin receptor 5HT4R in PMAH nodules
ABSTRACT Objective To analyze the morphological and functional characteristics of primary macronodular adrenal hyperplasia (PMAH) nodules carrying or not carrying ARMC5 mutations and the consequences of the presence of mutations in terms of the pattern of macronodule composition and functional state. Subjects and methods The analyses were performed by he

3. Dynamic changes of central thyroid functions in the management of Cushing's syndrome
ABSTRACT Objective The aim of this study was to determine the frequency of central thyroid dysfunctions in Cushing's syndrome (CS). We also aimed to evaluate the frequency of hyperthyroidism due to the syndrome of the inappropriate secretion of TSH (SITSH), which was recently defined in patients with insufficient hydrocortisone replacement after surgery. M

4. A review of Cushing's disease treatment by the Department of Neuroendocrinology of the Brazilian Society of Endocrinology and Metabolism
ABSTRACT The treatment objectives for a patient with Cushing's disease (CD) are remission of hypercortisolism, adequate management of co-morbidities, restoration of the hypothalamic-pituitary-adrenal axis, preservation of fertility and pituitary function, and improvement of visual defects in cases of macroadenomas with suprasellar extension. Transsphenoidal

5. Growth hormone deficiency with advanced bone age: phenotypic interaction between GHRH receptor and CYP21A2 mutations diagnosed by sanger and whole exome sequencing
SUMMARY Isolated growth hormone deficiency (IGHD) is the most common pituitary hormone deficiency and, clinically, patients have delayed bone age. High sequence similarity between CYP21A2 gene and CYP21A1P pseudogene poses difficulties for exome sequencing interpretation. A 7.5 year-old boy born to second-degree cousins presented with severe short stature (h

6. An activating mutation in the CRHR1 gene is rarely associated with pituitary-dependent hyperadrenocorticism in poodles
OBJECTIVES: Pituitary-dependent hyperadrenocorticism is the most common cause of naturally occurring hypercortisolism in dogs. CRHR1 expression in human and dog corticotrophinomas suggested that this gene affects pituitary tumorigenesis. The present study aimed to investigate mutations in the CRHR1 coding region in poodles with pituitary-dependent hyperadre

7. Recommendations of the Neuroendocrinology Department of the Brazilian Society of Endocrinology and Metabolism for the diagnosis of Cushing’s disease in Brazil
ABSTRACT Although it is a rare condition, the accurate diagnosis and treatment of Cushing’s disease is important due to its higher morbidity and mortality compared to the general population, which is attributed to cardiovascular diseases, diabetes mellitus and infections. Screening for hypercortisolism is recommended for patients who present multiple and p

8. Qualidade e quantidade do leite produzido por cabras da raça Saanen submetidas a estresse por três dias consecutivos
Estudou-se o efeito do estresse fisiológico, via administração pontual de ACTH, sobre os níveis de cortisol e a quantidade e qualidade do leite produzido. Para tanto, 12 cabras da raça Saanen foram alocadas em dois grupos experimentais: o grupo ACTH recebeu 0,6 UI de ACTH/kg PV, e o grupo placebo recebeu solução placebo. A produção de leite, os perc

9. Análise de mutação germinativa do Tpit em cães da raça Poodle com hiperadrenocorticismo ACTH-dependente
O hiperadrenocorticismo ACTH-dependente (HACAD) apresenta elevada incidência em cães da raça Poodle, sendo que membros da mesma família têm sido acometidos pela doença, sugerindo envolvimento genético. Tpit é um fator de transcrição obrigatório para a expressão do gene da pro-opiomelanocortina e para a diferenciação terminal dos corticotrofos.

10. Effects of a hydroalcoholic extract of Turnera diffusa Willd. ex Schult., Turneraceae, in tests for adaptogenic activity
The objective of the present study was to assess whether Turnera diffusa Willd. ex Schult., Turneraceae, (TD), plant known in popular medicine as tonic and aphrodisiac, has other effects that are characteristic of an adaptogen substance, such as improvement of the memory and reduction of the damage caused by stress. We carried out an initial screening to det

11. Seis novos casos confirmam o perfil clínico molecular de deficiência combinada de 17 alfa-hidroxilase/17,20-liase no Brasil
Em 2004, segundo Costa-Santos e cols., p.W406R e p.R362C correspondiam a 50% e 32% dos alelos mutantes do gene CYP17A1, respectivamente, em 24 pacientes de 19 famílias brasileiras com deficiência da 17α-hidroxilase. Apresentamos os dados clνnicos e moleculares de seis pacientes de três famílias consanguíneas brasileiras com deficiência da 17α-hidrox

12. Papel da via lkaros-FGFR4 na evolução pós-cirúrgica dos pacientes com doença de Cushing / Ikaros-FGFR4 pathway: role in the postoperative outcome of Cushings disease
Introduction: The mechanisms involved in the molecular pathogenesis of corticotroph pituitary tumors are complex, heterogeneous and in most cases remain unknown. Changes in the expression of components of Ikaros (Ik) pathway, such as receptor 4 of fibroblast growth factor (FGFR4), have been detected in pituitary tumors including corticotropinomas. Imbalance
