It has recently been noted that peripheral nerve fibres are involved in the course of chronic liver disease. The existence of hepatic polyneuropathy is still a matter of debate. A series of 29 subjects (not including diabetics or alcoholics) were examined clinically and electromyographically. Signs of distal lower extremity polyneuritis (paresthesia, hypoesthesia and osteotendinous hypo-areflexia) were noted in 31%. Latent neuropathy was observed in the form of slow maximum and minimum motor conduction rates in clinically unimpaired nerves. Electromyographical alterations were more evident in subjects with frankly chronic as opposed to barely chronic liver disease.

Despite the study of BCR::ABL1-positive and -negative myeloproliferative neoplasms (MPNs) providing seminal insights into cancer biology, tumor evolution and precision oncology over the past half century, significant challenges remain. MPNs are clonal hematopoietic stem cell-derived neoplasms with heterogenous clinical phenotypes and a clonal architecture which impacts the often-complex underlying genetics and microenvironment. The major driving molecular abnormalities have been well characterized, but debate on their role as disease-initiating molecular lesions continues.

The neurobiological mechanisms driving the ictal-interictal fluctuations and the chronification of migraine remain elusive. We aimed to construct a composite genetic-microRNA model that could reflect the dynamic perturbations of the disease course and inform the pathogenesis of migraine. We prospectively recruited four groups of participants, including interictal episodic migraine (i.

Introduction: Acute kidney injury (AKI) in patients with acute-on-chronic liver failure (ACLF) is driven by the severity of systemic inflammation, acute portal hypertension driving circulatory dysfunction, hyperbilirubinemia, and toxicity of bile acids. The spectrum is mostly structural, associated with reduced response to vasoconstrictors. The progression is rapid and need of renal replacement therapy and extracorporeal therapies may be required for the management.

Background: Migraine progression, particularly from episodic to chronic migraine (CM), increases disease burden and healthcare costs. Understanding the new concept of "Medication Underuse Headache" should encourage the health care provider to consider early intervention with calcitonin gene-related peptide (CGRP) monoclonal antibodies. Galcanezumab given early in the course of the disease, may prevent migraine chronification and have a robust response, moreso than when initiated in later stages of migraine.

Background And Purpose: Granulomatosis with polyangiitis (GPA) and eosinophilic granulomatosis with polyangiitis (EGPA) are the most common causes of chronic sinusitis from systemic granulomatous diseases. While both are small- to medium-sized vasculitis with necrotizing granulomas, they have different clinical courses and prognoses. High-density sinus opacification has been reported in allergic fungal sinusitis with eosinophilic infiltrates.
