NAFLD is common in PCOS patients and increased androgen bioavailability may be implicated, in combination with metabolic abnormalities. Liver evaluation is proposed in PCOS patients, especially in those with metabolic syndrome.

Nonalcoholic fatty liver disease (NAFLD) is the most common cause of chronic liver disease in the Western world comprising a spectrum of liver damage from fatty liver infiltration to end-stage liver disease, in patients without significant alcohol consumption. Increased prevalence of NAFLD has been reported in patients with polycystic ovary syndrome (PCOS), one of the most common endocrinopathies in premenopausal women, which has been redefined as a reproductive and metabolic disorder after the recognition of the important role of insulin resistance in the pathophysiology of the syndrome. Obesity, in particular central adiposity and insulin resistance are considered as the main factors related to NAFLD in PCOS. Moreover, existing data support that androgen excess, which is the main feature of PCOS and is interrelated to insulin resistance, may be an additional contributing factor to the development of NAFLD. Although the natural history of NAFLD remains unclear and hepatic steatosis seems to be a relatively benign condition in most patients, limited data imply that advanced stage of liver disease is possibly more frequent in obese PCOS patients with NAFLD. PCOS patients, particularly obese patients with features of the metabolic syndrome, should be submitted to screening for NAFLD comprising assessment of serum aminotransferase levels and of hepatic steatosis by abdominal ultrasound. Lifestyle modifications including diet, weight loss and exercise are the most appropriate initial therapeutic interventions for PCOS patients with NAFLD. When pharmacologic therapy is considered, metformin may be used, although currently there is no medical therapy of proven benefit for NAFLD. Long-term follow up studies are needed to clarify clinical implications and guide appropriate diagnostic evaluation, follow-up protocol and optimal treatment for PCOS patients with NAFLD.

The term disorders of sex development (DSD) includes congenital conditions in which development of chromosomal, gonadal or anatomical sex is atypical. Mutations in genes present in X, Y or autosomal chromosomes can cause abnormalities of testis determination or disorders of sex differentiation leading to 46,XY DSD. Detailed clinical phenotypes allow the identification of new factors that can alter the expression or function of mutated proteins helping to understand new undisclosed biochemical pathways. In this review we present an update on 46,XY DSD aetiology, diagnosis and treatment based on extensive review of the literature and our three decades of experience with these patients.

Results of this study suggest that laparoscopic adrenalectomy should be the treatment of choice for benign adrenal tumors. However, experience in advanced laparoscopic and open abdominal surgery is necessary in the management of large adrenal tumors.

Objective: To investigate the possibility of a different prevalence of subclinical Cushing's syndrome (SCS) and potentially related morbidities between patients with unilateral adrenal incidentalomas (UAI) and bilateral adrenal incidentalomas (BAI), as existing data are few and controversial. Design: Prospective observational study. Methods: Clinical examination, biochemical tests, and hormonal evaluation were performed in 298 consecutive patients with adrenal incidentalomas, unilateral in 224 patients (75.2%), bilateral in 74 patients (24.8%), with apparently benign masses based on imaging characteristics and after exclusion of overt endocrine disease. The diagnosis of SCS was based on a post-dexamethasone suppression test (2 mg dexamethasone/24 h for 48 h), with serum cortisol level R1.8 mg/dl combined with at least one abnormal result of the other hormonal measurements. Results: SCS was diagnosed in 66 out of 298 (22.1%) patients, being more frequent in patients with BAI (35.1 vs 17.9%, PZ0.003, for BAI and UAI respectively). Hypertension, type 2 diabetes mellitus, impaired glucose tolerance, and dyslipidemia were of a similar frequency in both groups. SCS patients with UAI and BAI did not differ in age, gender, BMI, waist circumference, and mass size. Factors related to SCS were the presence of BAI (OR, 3.24; 95% CI, and mass size (OR, 2.63; 95% CI,. Conclusion: BAI patients present more often with SCS when compared with UAI patients; however, morbidities potentially related to subtle cortisol hypersecretion were of a similar frequency in both groups. Further studies are needed to clarify whether this difference in hormonal activity may be related to different pathophysiologies.
