Pancreas and vertebral body MRI-PDFF is well correlated in NAFLD patients and both of them are higher in diabetic patients which may explain increased bone fractures in diabetics. MRI-PDFF can be used to demonstrate fat fractions of different organs and tissues and to understand fat metabolism.

The frequency of sexual dysfunction (SD) is not very well known in patients with chronic hepatitis C. In this study, the prevalence of SD and its correlations with psychological and biological variables was assessed in 46 HCV positive patients. The mean age of patients was 46.4+/-9.4 y; the mean duration of HCV infection was 43.4+/-34.0 months; 52% were male; 89% were living with a spouse. SD was assessed using the Arizona Sexual Experiences Scale (ASEX), the level of anxiety and depression measured with the Hospital Anxiety and Depression Scale (HADS). Biochemical parameters were also assessed. Overall, as indicated by ASEX criteria, SD was observed in 35% of our patients. Of 24 males, 21% described SD; problems with drive (25%), arousal (17%) and erection (17%) were the most frequent complaints. Of 22 female patients, 50% described SD; problems with drive (55%) arousal (50%), and reaching orgasm (59%) were the most frequent complaints. Total ASEX scores were correlated with age (P<0.07, significant at trend level), education (P<0.001), and was higher in female patients (P<0.02). After controlling for the effects of age, sex, education, duration of HCV and marital status, depression levels could still significantly predict the SD (P<0.05). Moreover, even after controlling the effects of all other variables, gamma glutamyl transpeptidase (GGT) levels could predict the SD status of the patients (P<0.05). Our results indicate that the prevalence of SD was 35% in HCV-infected patients and the level of depression and GGT levels were predictive of patients SD status.

A treatment strategy comprising diet, exercise and management of associated metabolic conditions is associated with improvement in aminotransferases among patients with NAFLD. Further investigation is needed to examine the long-term efficacy of this approach on liver histology and clinical outcomes.

With use of on-site cytopathological evaluation and combined use of CS and CB, the diagnostic accuracy of liver tumours approaches 100% and also significantly improve diagnostic and subtyping accuracy of liver malignancies.
