Pediatric metabolic and bariatric surgery: indications and preoperative multidisciplinary evaluation.

The standard of care for pediatric patients with severe obesity considering metabolic and bariatric surgery is a preoperative multidisciplinary evaluation. A multidisciplinary team allows for the efficient use of variable personnel expertise to evaluate, manage, and support a pediatric patient and family through metabolic and bariatric surgery. This review discusses the purpose, recommended team members, patient selection, content, and benefits of the multidisciplinary preoperative evaluation.

Neurosyphilis in patients with HIV.

Syphilis is a resurgent sexually transmitted infection in the UK that is disproportionately diagnosed in patients living with HIV, particularly in men who have sex with men. Syphilis appears to present differently in patients with HIV, particularly in those with severe immunosuppression. Progression to neurosyphilis is more common in HIV coinfection and can be asymptomatic, often for several years.

Discomfort and the cortical haemodynamic response to coloured gratings.

In five experiments we measured the amplitude of the haemodynamic response to visual patterns using near infrared spectroscopy of the visual cortex. The patterns were gratings with bars that differed in chromaticity but not in luminance. In all experiments, with a wide range of chromaticities of the grating bars, the amplitude of the haemodynamic response increased with the separation of the chromaticities in the CIE 1976 UCS diagram.
