Isolated rapid eye movement sleep behavior disorder is a prodrome of α-synucleinopathies. Using positron emission tomography, we assessed changes in Parkinson's disease-related motor and cognitive metabolic networks and caudate/putamen dopaminergic input in a 4-year longitudinal imaging study of 13 male subjects with this disorder. We also correlated times to phenoconversion with baseline network expression in an independent validation sample.

Segmental absence of intestinal musculature (SAIM) was first identified as a cause of intestinal perforation and remains difficult to diagnose clinically. Diagnosing SAIM preoperatively can be difficult; however, detection during the surgical procedure may be feasible if gross observations reveal bowel alterations such as a thinned-out wall, signs of gangrenous changes, or adjacent bowel dilatation. A final diagnosis can be made with the help of histopathology, making it a gold standard.

- - The posterior femoral cutaneous nerve (PFCN) is important for understanding sensory issues in the gluteal region, especially due to risks from injuries and pressure ulcers.
- - During a routine anatomical dissection of a 56-year-old male cadaver, a significant connection between the PFCN and the inferior gluteal nerve (IGN) was identified, which is important for diagnostic and surgical procedures.
- - This connection could help improve nerve block procedures for surgeries related to the thigh, knee, and upper leg, as the motor response from the IGN can indicate how effectively the PFCN is blocked.
