Objective: In a recent sham-controlled 13-session prolonged continuous theta burst stimulation intervention protocol, recovery from upper limb fracture at both 1 and 3 months was better than anticipated in patients assigned to the sham intervention group. To determine whether potential placebo effect and close patient monitoring affected recovery, the current study aimed to compare clinical outcomes between sham-treated participants who also received standard care with similarly injured patients who only received standard care.

Methods: Twenty participants with isolated upper limb fractures from the sham group were seen 13 times post-fracture (1 baseline session, 10 treatments, and 2 follow-ups [1 and 3 months]) over 3 months.

Aims: FGFR-fused central nervous system (CNS) tumours are rare and are usually within the glioneuronal and neuronal tumours or the paediatric-type diffuse low-grade glioma spectrum. Among this spectrum, FGFR2 fusion has been documented in tumours classified by DNA-methylation profiling as polymorphous low-grade neuroepithelial tumours of the young (PLNTY), a recently described tumour type. However, FGFR2 fusions have also been reported in glioneuronal tumours, highlighting the overlapping diagnostic criteria and challenges.

  • Paranasal sinuses can help identify individuals by comparing post-mortem CT (PMCT) scans with ante-mortem CT (AMCT) scans, but security issues arise when sharing raw AMCT images for suspected identities.
  • The study aimed to create an identification score, called IDScore, by analyzing CT slices from two successive AMCTs and assessing their similarities among radiologists.
  • The validated IDScore method achieved perfect identification rates (100% sensitivity and specificity) without needing to access full AMCT images, addressing ethical concerns during identity verification.

We assessed the impact of day-to-day sleep quality and psychological variables (catastrophizing, negative affect, and positive affect) to within-day pain fluctuations in 42 females with painful temporomandibular disorders (TMD) using electronic diaries. More specifically, we examined the contribution of these variables to the likelihood of experiencing pain exacerbations defined as 1) an increase of 20 points (or more) in pain intensity on a 0 to 100 visual analog scale from morning to evening, and/or 2) a transition from mild-to-moderate pain over the course of the day; and pain decreases defined as 3) a decrease of 20 points (or more) in pain intensity (visual analog scale) from morning to evening, and/or 4) a reduction from moderate-to-mild pain over the day. The results indicated significantly main effects of sleep on both pain exacerbation outcomes (both P's < .

A novel methylation class, "neuroepithelial tumor, with PLAGL1 fusion" (NET-PLAGL1), has recently been described, based on epigenetic features, as a supratentorial pediatric brain tumor with recurrent histopathological features suggesting an ependymal differentiation. Because of the recent identification of this neoplastic entity, few histopathological, radiological and clinical data are available. Herein, we present a detailed series of nine cases of PLAGL1-fused supratentorial tumors, reclassified from a series of supratentorial ependymomas, non-ZFTA/non-YAP1 fusion-positive and subependymomas of the young.
