Background: Stiff-person syndrome is a rare disorder characterized by rigidity of axial or limb muscles with episodes of co-contraction of agonist and antagonist muscles during the spasms. In some patients axial or limb involvement may predominate and may have unusual manifestations.
Design: Case report.
Setting: Tertiary care teaching hospital.
Patient: A 42-year-old farmer presented with seasonal occurrence of hiccup and vomiting during summer months for the last 3 years. He had painful lower limb spasms lasting for 2-3 minutes every 10-15 minutes for the past 20 days. His neurological examination was normal, erythrocyte sedimentation rate (ESR) was 50 mm at 1st hour, and cerebrospinal fluid protein 78 mg/dL without pleocytosis. Radiograph of chest, abdominal ultrasound, and craniospinal magnetic resonance imaging were normal. The patient improved on diazepam.
Conclusion: Our patient is a forme fruste of stiff person syndrome with hiccups and vomiting due to diaphragmatic spasm.

Introduction: Mixed connective tissue disease (MCTD) patients often have myositis, however, myopathological and clinical data for MCTD are limited. Recent reports have shown that the pathology of MCTD myositis resembles that of immune-mediated necrotizing myopathy (IMNM), whereas earlier reports described perifascicular atrophy or inflammatory infiltrates predominantly in the perivascular region in MCTD myositis. We aim to describe the clinical and myopathological features of MCTD myositis.

Prior to international competitions, dressage horses are evaluated for fitness to compete while trotting in hand on a firm surface. This study compares the kinematics of experienced dressage horses trotting under fitness-to-compete conditions vs. performing collected and extended trot when ridden on a sand-fiber arena surface.

Background: Supernumerary digits, or polydactyly, have been described in various species including humans, wild and domestic animals. In horses, it represents the most common congenital limb malformation, which has only been described in isolated cases or nuclear families. Molecular aetiology has not been reported.

This study focuses on the development and evaluation of the OrthoNail hybrid intramedullary implant for lower limb lengthening in patients requiring significant skeletal reconstruction. The implant addresses the challenges in load-bearing during rehabilitation, providing a robust solution that is capable of supporting physiological loads. Mechanical tests, including axial compression, tension, torsion, and 3,4-point bending, determined the implant's load capacity and fatigue resistance, while finite element analysis assessed stress distributions in bone tissue and around screw holes during single-leg stance, with boundary conditions derived from Orthoload database data.

Objective: Diffusion tensor imaging (DTI) showed promising results in diagnosing upper limb neuropathies, but its value in patients with foot drop due to peroneal neuropathy has not yet been investigated. We aim to establish reference values for DTI metrics of the healthy peroneal nerve and to evaluate differences in DTI metrics between patients and healthy controls.
Methods: Diffusion-weighted images (DWI) from 22 pathological nerves, 14 asymptomatic patients' nerves and 65 healthy peroneal nerves were processed for quantitative assessment of fractional anisotropy (FA), radial diffusivity (RD), axial diffusivity and mean diffusivity.
