The Emotional and Ethical Dilemmas of Body Integrity Dysphoria: A Case Report From England.
Cureus
October 2024
General Adult Psychiatry, Mersey Care National Health Service (NHS) Foundation Trust, Liverpool, GBR.
Article Synopsis
- - Body integrity dysphoria is a rare disorder characterized by a persistent desire for a specific physical disability, with some individuals seeking surgical or self-amputation to fulfill this desire.
- - A case report details a 52-year-old man who wished to become an amputee since childhood and even attempted to amputate his lower limb by a train, but denied any suicidal intent; he also has a history of congenital heart issues and an autism spectrum diagnosis.
- - Treatment strategies focus on psychological support and risk reduction rather than attempting to change the patient's thoughts, with ongoing discussions about the disorder's causes and the challenges in finding effective management approaches.
Electron Transport through Linear-, Broken-, and Cross-Conjugated Polycyclic Compounds.

Quantum interference (QI) effects offer unique opportunities to modulate charge transport through single molecules. In recent years, several transmission selection rules have been developed to determine constructive and destructive QIs in an intuitive and simple manner, although some of these rules fail for cross-conjugated systems. In this work, we evaluate the performance of distinct transmission rules on a broad series of anthracene and fluorene derivatives with distinctive structural features including linear-, broken-, and cross-conjugation, heteroatoms, and five-membered rings as such species affords a predictive challenge for the qualitative selection rules for QI effects.

Surface-energy anisotropy of metals is crucial for the stability and structure, however, its determining factors and structure-property relationship are still elusive. Herein, we identify three key factors for predicting surface-energy anisotropy of pure metals and alloys: the surface-atom density, coordination numbers and atomic radius. We find that the coupling rules of surface geometric determinants, which determining surface-energy anisotropy of face-centred-cubic (FCC), hexagonal-close-packed (HCP) and body-centred-cubic (BCC) metals, are essentially controlled by the crystal structures instead of chemical bonds, alloying or electronic structures.

Refraction is a basic beam bending effect at two media's interface. While traditional studies focus on stationary boundaries, moving boundaries or potentials could enable new laws of refractions. Meanwhile, media's discretization plays a pivotal role in refraction owing to Galilean invariance breaking principle in discrete-wave mechanics, making refraction highly moving-speed dependent.

Hip bipolar hemiarthroplasty, a widely employed surgical intervention for managing hip fractures and degenerative hip diseases, can pose significant challenges when revisions become necessary due to complications such as implant loosening, instability, or breakage. This case report presents the intricate management of a 58-year-old male who presented with worsening left hip pain a decade after undergoing hip replacement surgery. Despite a thorough preoperative assessment ruling out infection, intraoperative complexities included the necessity for extended trochanteric osteotomy (ETO) to address a broken stem and associated metallosis.
