Cell populations and muscle fiber morphology associated with acute and chronic muscle degeneration in lumbar spine pathology.

Many chronic musculoskeletal conditions are associated with loss of muscle volume and quality, resulting in functional decline. While atrophy has long been implicated as the mechanism of muscle loss in these conditions, recent evidence has emerged demonstrating a degenerative phenotype of muscle loss consisting of disrupted muscle fiber membranes, infiltration of cells into muscle fibers, and as previously describer, possible replacement of muscle fibers by adipose tissue. Here, we use human lumbar spine pathology as a model system to provide a more comprehensive analysis of the morphological features of this mode of muscle loss between early and late stages of disease, including an analysis of the cell populations found in paraspinal muscle biopsies from humans with acute vs chronic lumbar spine pathology. Using longitudinal sections, we show that degeneration of muscle fibers is localized within a fiber (ie, focal), and is characterized by discontinuous or ragged membrane disruption, cellular infiltration, and apparently vacant space containing limited numbers of nuclei and hyper-contractile cell debris. Samples from patients with acute and chronic pathology demonstrate similar magnitudes of muscle degeneration, however, larger proportions of PDGFRβ-positive progenitor cells and leukocytes were observed in the acute group, with no differences in myogenic cells, macrophages, or T-cells. By better understanding the cell population behaviors over the course of disease, therapies can be optimized to address the appropriate targets and timing of administration to minimize the functional consequences of muscle degeneration in lumbar spine pathology.

Sex Differences of Migraine: Results of a Nationwide Home-based Study in Turkey.

The prevalence of migraine was found to be more than three-fold higher in women as compared with men, and in addition to differences in prevalence rates, the characteristics and associated features might also differ between the sexes. The aim of this study was to compare sex-specific features of migraine and demographic parameters in a nationwide population-based study in Turkey.

Efficacy of anti-inflammatory moisturizer vs hydrophilic cream in elderly patients with moderate to severe xerosis: A split site, triple-blinded, randomized, controlled trial.

Xerosis is a common problem among the elderly, characterized by dry-scaling erythema, fissuring, or pruritus, which could be treated by anti-inflammatory moisturizers without side effects of steroids.

Percutaneously inserted unilateral lead migration salvaged with a paddle electrode.

Lead migration has been regarded as a frequent complication after percutaneous spinal cord stimulation (SCS). Thus far, repeated reinsertion of leads or replacement of paddle electrode after removing percutaneous leads have been used, but a salvage surgical technique using the remaining electrode has not been reported. Here, we describe a case in which unilateral lead migration was successfully treated with the insertion of a paddle electrode.

Not Just Another Headache: Cerebral Venous Sinus Thrombosis in a Patient With Isolated Antithrombin III Deficiency.

Cerebral venous sinus thrombosis (CVST) is a rare condition. Symptoms and signs arise from a combination of thrombosis of cerebral veins and increased intracranial pressure. The most common presenting symptom is a non-descriptive headache, but presentation varies with underlying etiology. CVST requires a high index of suspicion to diagnose, particularly in those without apparent risk factors. Evaluation and diagnosis should include a combination of a thorough history, ophthalmoscopic examination, laboratory studies, and imaging. Management is multidimensional and aims to reverse the underlying causes, and prompt treatment with anticoagulation by heparin to decrease thrombotic burden, risk of permanent neurological deficits, and death. In the present study, we report the case of a 61-year-old man referred to the emergency department by an ophthalmologist for bilateral papilledema and eventually diagnosed with CVST secondary to isolated antithrombin III deficiency. Although CVST is uncommon, this case is worthwhile to report as the presentation is unique, and it requires a high index of clinical awareness for timely diagnosis and early therapeutic intervention.

Ileocolic intussusception: ultrasound-guided hydrostatic reduction with sedation and analgesia.

The first-choice treatment for ileocolic intussusception is imaging-guided reduction with water, air, or barium. The objectives of the current study were to evaluate the efficacy and safety of ultrasound-guided reduction of intussusception using water in patients under sedation and analgesia. We compare this approach with our previous experience in reduction using barium under fluoroscopic guidance without sedation and analgesia and investigate what factors predispose to surgical correction.
