Evaluation of fructosamine as a parameter of blood glucose control in diabetic pregnant women
Conclusion The levels of fructosamine can be used as further parameter to aid self monitoring of blood glucose to evaluate hyperglycemias and glycemic variability, however, this can underestimate hypoglycemias in pregnant women carrying small-for-gestational age fetuses.

The prevalence of glucose metabolism disturbances in Chinese Muslims and possible risk factors: a study from northwest China
Conclusions In northwest China, the prevalence of DM was higher in the Muslim population, and it was special higher on the 20-year-old age compared to the Han. This might be explained by the potential genetic differences and poor dietary habits. Objetivo Avaliar a prevalência de diabetes melito (DM) e pré-diabetes melito (PDM) na população muçulmana no noroeste da China e discutir os fatores de risco. Materiais e métodos Selecionamos três vilarejos de acordo com a renda e a população, usando uma amostra estratificada e por cluster. Os sujeitos eram residentes com ≥ 20 anos de idade e de famílias que estav...

Serum levels of retinol binding protein 4 in women with different levels of adiposity and glucose tolerance
Conclusions Although RBP4 have shown lower levels in diabetic and obese, a strong correlation with HOMA-IR index highlights that, in our study, there is growing IR when there is an increasing in RBP4 levels. Objetivo A proteína carreadora do retinol 4 (RBP4) é uma adipocina responsável pelo transporte de vitamina A (retinol). Estudos associam os níveis aumentados de RBP4 com a gravidade do diabetes melito tipo 2 (DM2) e resistência à insulina (RI). O objetivo deste estudo foi investigar como esses níveis se comportam em mulheres com ampla variação do índice de massa corporal (IMC) e tolerância à glicose. Suj...

The role of imaging in congenital adrenal hyperplasia
Congenital adrenal hyperplasia (CAH) is an autossomic recessive disorder caused by impaired steroidogenesis. Patients with CAH may present adrenal insufficiency with or without salt-wasting, as well as various degrees of virilization and fertility impairment, carrying a high incidence of testicular adrenal rest tumors and increased incidence of adrenal tumors. The diagnosis of CAH is made based on the adrenocortical profile hormonal evaluation and genotyping, in selected cases. Follow-up is mainly based on hormonal and clinical evaluation. Utility of imaging in this clinical setting may be helpful for the diagnosis, manage...

Persistence of intrasellar trigeminal artery and simultaneous pituitary adenoma: description of two cases and their importance for the differential diagnosis of sellar lesions
Persistent trigeminal artery (PTA) is the most frequent embryonic communication between the carotid and vertebrobasilar systems. However, hormonal changes or the association of PTA with other sellar lesions, such as pituitary adenomas, are extremely rare. The aim of the present study was to report two patients with intrasellar PTA and simultaneous pituitary adenoma in order to emphasize the importance of differential diagnoses for sellar lesions. Case 1. A female patient, 41 years old, was admitted with a history of chronic headache (> 20 years). Pituitary magnetic resonance imaging (MRI) showed a rounded lesion in the ...

Aggressive pituitary lesion with a remarkably high Ki-67
The uncommon aggressive pituitary tumors are named carcinomas when metastases are detected, either in the central nervous system and/or systemically. Some cases are associated with hormonal overproduction, but most are diagnosed because of local symptoms. These neoplasias are generally refractory to current treatments. A 51 year-old woman presented sudden onset of headache, left arm paresis and left facial hypoesthesia. Computed tomography scan and magnetic resonance imaging revealed a pituitary tumor invading the left sphenoidal and cavernous sinuses. Laboratory data excluded hormonal hypersecretion. The patient underwent...

3?-hydroxysteroid dehydrogenase type II deficiency on newborn screening test
We present the first report of 3β-HSD type II deficiency genotype-proven detected at the Newborn Screening Program in Brazil. The case described herein corroborates the strong genotype-phenotype correlation associated with the HSD3B2 p.P222Q mutation, which leads to a classic salt-wasting 3β-HSD deficiency. Further evaluation of 17OHP assays used in newborn screening tests would aid in determining their reproducibility, as well as the potential significance of moderately elevated 17OHP levels as an early indicator to the diagnosis of other forms of classic CAH, beyond 21-hydroxylase deficiency.A deficiência da enzima 3Î...

Rare association between penile squamous cell carcinoma and parathyroid related peptide (PTH-rP) secretion
We report on a rare case of an adult with severe hypercalcemia secondary to the ectopic secretion of parathyroid-related peptide (PTH-rP) from a penile squamous cell cancer (PC). A patient of 47 years old was admitted with warty lesions and areas of ulceration covered by purulent material in a large area of the groin, scrotum and penis. Laboratory tests revealed severe hypercalcemia and elevation of PTH-rP; the biopsy reported PC. Hypercalcemia was successfully treated with zoledronic acid, however, the tumor displayed aggressive behavior, which resulted in a poor prognosis for the patient.Relatamos um caso raro em um adul...

Lack of association between polymorphisms in the UBASH3A gene and autoimmune thyroid disease: a case control study
Conclusion: Rs11203203 and rs3788013 in UBASH3A gene may not be associated with AITD patients in Chinese Han population. Objetivo: O objetivo deste estudo foi investigar a variação no gene UBASH3A com a doença tiroidiana autoimune e características clínicas na população chinesa Han.

Obesity, insulin resistance and comorbidities ? Mechanisms of association
Overall excess of fat, usually defined by the body mass index, is associated with metabolic (e.g. glucose intolerance, type 2 diabetes mellitus (T2DM), dyslipidemia) and non-metabolic disorders (e.g. neoplasias, polycystic ovary syndrome, non-alcoholic fat liver disease, glomerulopathy, bone fragility etc.). However, more than its total amount, the distribution of adipose tissue throughout the body is a better predictor of the risk to the development of those disorders. Fat accumulation in the abdominal area and in non-adipose tissue (ectopic fat), for example, is associated with increased risk to develop metabolic and non...
