Abstract
Polymyalgia rheumatica (PMR) is a chronic inflammatory disease which affects the connective vascular tissue, characterized by pain accompanied by morning stiffness, predominantly of the neck muscles, hip and shoulder girdle. Usually, patients with this disease are >50 years of age and biological inflammatory syndrome is present with an increase in both the erythrocyte sedimentation rate and C-reactive protein levels, aspects similar to giant cell arteritis. The aim of the present review was to depict the current pathogenic hypothesis, diagnostic and treatment approach for patients with PMR, and novelties since the development of the currently used 2012 European League Against Rheumatism and American College of Rheumatology provisional classification criteria. PMR is a prevalent disease that can occasionally prove difficult to diagnose and treat. Possibly, the most abundant type of evidence and data revealed over the past decade have been acquired through musculoskeletal imaging, with implications in diagnosis, disease monitoring and relapse, prognosis and changes with treatment. Further research on pathophysiology is required to gain a deeper understanding of the underlying processes, which will serve as the foundation for future personalized treatments. In addition, there is an increasing demand for improved diagnostic techniques, which should include a further development of various imaging modalities, in order to provide accurate diagnosis and appropriate therapy.

Abstract
INTRODUCTION The main mechanism of death and the pathological appearance of cases of benzyl alcohol intoxication has not been fully investigated. Autopsy reports of cases of benzyl alcohol intoxication have not been published. CASE PRESENTATION A 24-year-old man was found in the state of cardiopulmonary arrest at a construction site. He had been performing paint stripping. He was immediately transferred to the hospital, but he did not recover. An autopsy showed focal coloring of the skin without any major caustic injury. A histopathological investigation showed vacuolar degeneration in the epidermis and dermo-epidermal junction, and severe erosion of the tracheal and bronchial mucosa. No pathological changes in the kidney were evident. A neuropathological investigation showed central chromatolysis of neuronal cells in pontine nuclei and grumose degeneration in the cerebellar dentate nucleus. The blood content of benzyl alcohol was 780.0 μg/mL. LESSONS Present case suggest that multiple pathways of exposure may be associated with more rapid progression in acute benzyl alcohol intoxication, and that early and/or severe involvement of the central nervous system rather than renal dysfunction may be associated with an early death.

Innate frequency-discrimination hyperacuity in Williams-Beuren syndrome mice. Cell 2022; 185:3877-3895.e21. [PMID: 36152627 PMCID: PMC9588278 DOI: 10.1016/j.cell.2022.08.022] [Citation(s) in RCA: 5] [Impact Index Per Article: 2.5] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/01/2022] [Revised: 06/14/2022] [Accepted: 08/24/2022] [Indexed: 01/26/2023]
Abstract
Williams-Beuren syndrome (WBS) is a rare disorder caused by hemizygous microdeletion of ∼27 contiguous genes. Despite neurodevelopmental and cognitive deficits, individuals with WBS have spared or enhanced musical and auditory abilities, potentially offering an insight into the genetic basis of auditory perception. Here, we report that the mouse models of WBS have innately enhanced frequency-discrimination acuity and improved frequency coding in the auditory cortex (ACx). Chemogenetic rescue showed frequency-discrimination hyperacuity is caused by hyperexcitable interneurons in the ACx. Haploinsufficiency of one WBS gene, Gtf2ird1, replicated WBS phenotypes by downregulating the neuropeptide receptor VIPR1. VIPR1 is reduced in the ACx of individuals with WBS and in the cerebral organoids derived from human induced pluripotent stem cells with the WBS microdeletion. Vipr1 deletion or overexpression in ACx interneurons mimicked or reversed, respectively, the cellular and behavioral phenotypes of WBS mice. Thus, the Gtf2ird1-Vipr1 mechanism in ACx interneurons may underlie the superior auditory acuity in WBS.

ICHIMATA S, HATA Y, HIROTA K, NISHIDA N. Histopathology of acute colchicine intoxication: novel findings and their association with clinical manifestations. J Toxicol Pathol 2022; 35:255-262. [PMID: 35832901 PMCID: PMC9255996 DOI: 10.1293/tox.2022-0007] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/12/2022] [Accepted: 02/16/2022] [Indexed: 11/19/2022] Open
Abstract
A 32-year-old woman attempted suicide by ingesting Gloriosa bulbs and died approximately
2 days later. Toxicological examination revealed a potentially fatal blood concentration
of colchicine (0.096 mg/L). In addition to the increased mitotic figures in the
gastrointestinal mucosa, a unique finding for acute colchicine intoxication, pathological
examination showed microvesicular lipid droplets in the liver, kidney, heart, and
conduction system. Furthermore, central chromatolysis of neurons was observed in the
pontine nucleus, medial accessory olivary nucleus, nucleus of the solitary tract, and
nucleus ambiguus. Grumose degeneration of the cerebellar dentate nucleus was also evident.
These pathological findings may help identify colchicine intoxication, even in the absence
of evidence suggesting ingestion during autopsy. Moreover, pathological changes in the
heart and central nervous system may be associated with the development of serious
complications of acute colchicine intoxication.
