Central diabetes insipidus (CDI) is the most common complication of endoscopic endonasal surgery (EES) for craniopharyngioma. However, some cases of CDI could spontaneously resolve during the follow-up period. Hence, this study aimed to determine the predictive factors for the spontaneous resolution of CDI. ⋯ Hydrocephalus at diagnosis, pituitary stalk injury, and the Hong et al HI pattern might be predictors of the spontaneous resolution of CDI following EES for craniopharyngioma.

Tissue protrusion (TP) is a possible cause of cerebral infarction after carotid artery stenting (CAS). Using optical frequency domain imaging (OFDI) and angioscopy, we investigated the relationship between the morphological features of TP and postoperative new ischemic lesions on magnetic resonance imaging (MRI)-diffusion weighted imaging (DWI) after CAS. ⋯ The height of TP on OFDI and mobile-TP on angioscopy after CAS were associated with postoperative new ischemic lesions on MRI-DWI. The intravascular evaluation using OFDI and angioscopy could be helpful for a detailed evaluation of TP.

Paralumbar muscle volume has been indicated as an important factor for patients reporting back pain. Our goal was to determine if there is a statistically significant relationship between the duration of patients' back pain symptoms (>12 weeks or ≤12 weeks) and paralumbar muscle volume. ⋯ Our results suggest that duration of symptoms may not be an accurate indicator for lumbar muscle volume. These novel findings are clinically valuable because lumbar muscle volume has been shown to be a marker for recovery. With this information, patients previously believed to be inoperable because of long-standing symptoms can be reevaluated.

Lower muscular weakness and gait disturbance are typical lumbar spinal stenosis (LSS) symptoms. Gait initiation and standing balance function are dependent on hip muscle groups, particularly gluteus medius (GMed). However, alterations to GMed in patients with LSS have not been studied. Therefore, we evaluated the impact of LSS on GMed in this study. ⋯ The degree of GMed atrophy is related to symptoms of LSS. Spine surgeons should be aware of the risk of GMed atrophy in patients with LSS with unilateral buttock pain.

The medical literature on prisoner health care is limited, despite data showing that prisoners experience high rates of physical and mental health challenges. We compared clinical outcomes for prisoners undergoing spine fusion with comparable nonincarcerated patients and determined what factors were implicated in differences in outcomes. ⋯ This is one of few studies investigating health care outcomes in prisoners. We found they had a significantly higher rate of nonunion than matched control patients from the general population treated at the same hospital, suggesting additional measures may be necessary postoperatively to support fusion in prisoners.
