Objectives: This study aims to investigate cases of acontractile bladder as the initial presentation of benign and malignant spinal conditions. The focus is on the challenges in making a diagnosis and the importance of a thorough neurological evaluation.
Methods: We conducted a retrospective case series involving three patients who exhibited symptoms of acontractile bladder. Detailed clinical histories, urodynamic studies, and imaging techniques such as lumbosacral magnetic resonance imaging (MRI) were analyzed. Histopathological findings from relevant biopsies were also taken into account.
Results: : A 14-year-old female presented with urinary retention, back pain, and an acontractile bladder on urodynamic study. Further examination, including lumbosacral MRI and histopathology, confirmed a diagnosis of metastatic Ewing's Sarcoma. : A 39-year-old female with urinary incontinence and elevated post-void residual exhibited delayed bladder sensation. Lumbar spine MRI revealed a grade I Schwannoma after surgical resection. : A 15-year-old male with lower urinary tract symptoms and an acontractile detrusor on urodynamic study was found to have a Tarlov cyst on lumbosacral MRI.
Conclusion: Atonic or Underactive bladder syndrome may be the initial presentation of a serious spinal condition. Complete neurological evaluation is mandatory if no obvious clinical cause.

Background: Autism Spectrum Disorder (ASD) is a complex neurodevelopmental condition emerging in early childhood, characterized by core features such as sociocommunicative deficits and repetitive, rigid behaviors, interests, and activities. In addition to these, disruptive behaviors (DB), including aggression, self-injury, and severe tantrums, are frequently observed in pediatric patients with ASD. The atypical antipsychotics risperidone and aripiprazole, currently the only Food and Drug Administration-approved treatments for severe DB in patients with ASD, often encounter therapeutic failure or intolerance.

The trade-off between the performances of the oxygen reduction reaction (ORR) and oxygen evolution reaction (OER) presents a challenge in designing high-performance aqueous rechargeable zinc-air batteries (a-r-ZABs) due to sluggish kinetics and differing reaction requirements. Accurate control of the atomic and electronic structures is crucial for the rational design of efficient bifunctional oxygen electrocatalysts. Herein, we designed a Sn-Co/RuO trimetallic oxide utilizing dual-active sites and tin (Sn) regulation strategy by dispersing Co (for ORR) and auxiliary Sn into the near-surface and surface of RuO (for OER) to enhance both ORR and OER performances.

Spore germination in is initiated by a cascade of activities of several proteins that culminates in the activation of SleC, a cell-wall-processing enzyme. We report herein the details of the enzymatic activities of SleC by the use of synthetic peptidoglycan fragments and of spore sacculi. The reactions include the formation of 1,6-anhydromuramate─a hallmark of lytic transglycosylase activity─as well as a muramate hydrolytic product, both of which proceed through the same transient oxocarbenium species.

Phenotypic plasticity may pave the way for rapid adaptation to newly encountered environments. Although it is often contested, there is growing evidence that initial plastic responses of ancestral populations to new environmental cues may promote subsequent adaptation. However, we do not know whether plasticity to cues present in the ancestral habitat (past-cue plasticity) can facilitate adaptation to novel cues.

Case: A 30-year-old man presented with left proximal tibia fracture (open Grade 3A) and a transverse lateral malleolus fracture (Weber B) following direct impact injury. Computed tomography revealed a rare posteromedial tubercle fibula fracture at the posterior inferior tibiofibular ligament (PITFL) insertion, with syndesmosis disruption. Initial damage control included an external fixator.
