Critical illness neuropathy

Kikuchi's disease (KD) also known as histiocytic necrotizing lymphadenitis is rare, idiopathic, generally self-limited cause of lymphadenitis. We present a case of twenty year young female who presented in critically ill state with fever, cervical and axillary lymphadenopathy, rash, vomiting and altered sensorium and found to have neurological, hepatic, renal and dermatological involvement. Kikuchi's disease should be considered in differential diagnosis of fever and lymphadenopathy and though benign can sometimes present with multi-organ involvement...

BACKGROUND: Critical illness polyneuromyopathy (CIPNM) increasingly is recognized as a source of disability in patients requiring intensive care unit (ICU) admission. The prevalence and impact of CIPNM on patients in the rehabilitation setting has not been established. OBJECTIVES: To determine the proportion of at-risk rehabilitation inpatients with evidence of CIPNM and the functional sequelae of this disorder. DESIGN: Prospective observational study...

Chronic inflammatory demyelinating polyradiculoneuropathy (CIDP) is an acquired autoimmune demyelinating polyneuropathy characterized by symmetrical diffuse weakness that also can rarely affect bulbar and respiratory muscles. The study objective was to describe perioperative outcomes of patients with CIDP who received general anesthesia. This retrospective observational study evaluated patients with active (diagnosed or treated within the previous year) CIDP who underwent general anesthesia at our institution between January 1, 2010, and December 31, 2015...

PURPOSE: Lyme disease is spreading worldwide, with multiple Borrelia species causing a broad range of clinical symptoms that mimic other illnesses. A validated Lyme disease screening questionnaire would be clinically useful for both providers and patients. Three studies evaluated such a screening tool, namely the Horowitz Multiple Systemic Infectious Disease Syndrome (MSIDS) Questionnaire. The purpose was to see if the questionnaire could accurately distinguish between Lyme patients and healthy individuals...

An average of 50-80% of patients treated in the intensive care unit is affected by disturbances of neuromuscular functions due to damage to the nerves and muscles, which has led to the terms critical illness polyneuropathy and myopathy. Both components occur in 30-50% of patients, while the others predominantly show a pure myopathy, while pure neuropathy is rare. Meanwhile, the descriptive term of the concept as intensive care unit-acquired weakness (ICUAW) is preferred. The most significant risk factors for the development of ICUAW are sepsis, multiorgan dysfunction and acute respiratory distress syndrome (ARDS)...

Glaucoma is a chronic, progressive, and debilitating optic neuropathy that causes retinal damage and visual defects. The pathophysiologic mechanisms of glaucoma remain ill-defined, and there is an indisputable need for contributions from basic science researchers in defining pathways for translational research. However, glaucoma researchers today face significant challenges due to the lack of a map of integrated pathways from bench to bedside and the lack of consensus statements to guide in choosing the right research questions, techniques, and model systems...

INTRODUCTION: We sought to determine the specificity of compound muscle action potential (CMAP) durations and amplitudes in a large critical illness neuromyopathy (CINM) cohort relative to controls with other neuromuscular conditions. METHODS: Fifty-eight patients with CINM who had been seen over a 17-year period were retrospectively studied. Electrodiagnostic findings of the CINM cohort were compared with patients with axonal peripheral neuropathy and myopathy due to other causes...

A 42-year-old patient presented with acute allodynia and hyperalgesia in her distal limbs, most severe in the innervation area of the ulnar nerve. The patient developed critical illness myopathy/polyneuropathy after septic shock 5 months prior to her presentation. After exclusion of differential diagnosis, "late onset small fiber neuropathy" after critical illness was diagnosed. Recent studies showed small fiber lesions during critical illness and in follow-up exams, where additionally neuropathic pain were proved...

PURPOSE: (18)F-fluorodeoxyglucose positron emission tomography combined with computed tomography (FDG-PET/CT) is a promising new tool for the identification of inflammatory, infectious, and neoplastic foci. The aim of our work was to evaluate the diagnostic value of FDG-PET/CT in patients treated on a neurological/neurosurgical ICU or stroke unit. METHODS: We performed a single-center, 10-year, retrospective evaluation of the value of FDG-PET/CT in critically ill adult patients with severe neurological disease...

Critical illness myopathy (CIM) and neuropathy are underdiagnosed conditions within the intensive care setting and contribute to prolonged mechanical ventilation and ventilator wean failure and ultimately lead to significant morbidity and mortality. These conditions are often further subdivided into CIM, critical illness polyneuropathy (CIP), or the combination-critical illness polyneuromyopathy (CIPNM). In this review, we discuss the epidemiology and pathophysiology of CIM, CIP, and CIPNM, along with diagnostic considerations such as detailed clinical examination, electrophysiological studies, and histopathological review of muscle biopsy specimens...

INTRODUCTION: Critically ill patients often develop tetraparesis. It has been debated whether this is caused by neuropathy, myopathy, or both. The aim was to determine the incidence of myopathy and neuropathy in weak patients in the intensive care unit by performing several electrophysiological examinations, including quantitative electromyography (qEMG). METHODS: Forty-nine patients referred for electrophysiological examination because of suspected critical illness-related weakness underwent qEMG, nerve conduction studies, and direct muscle stimulation...

BACKGROUND: Many patients who survive the intensive care unit (ICU) experience long-term complications such as peripheral neuropathy and nephropathy which represent a major source of morbidity and affect quality of life adversely. Similar pathophysiological processes occur frequently in ambulant patients with diabetes mellitus who have never been critically ill. Some 25 % of all adult ICU patients have diabetes, and it is plausible that ICU survivors with co-existing diabetes are at heightened risk of sequelae from their critical illness...

OBJECTIVE: After critical illness, some survivors experience long-term physical, functional, neurocognitive and/or mental health impairments, which has been termed "Post-Intensive Care syndrome" (PICS) [1]. A specific follow-up is required and many specialized follow-up clinics have been created both abroad and in France. The aim of this study is to evaluate long-term outcomes after critical illness, through the International Classification of Functioning, Disability and Health, and to analyse rehabilitation needs after intensive care unit (ICU) discharge...

BACKGROUND: Critical illness polyneuropathy (CIP) is a common complication of severe sepsis and systemic inflammatory response syndrome (SIRS). The risk factors for sepsis-induced CIP have not been well established. AIM: The aim of this study was to find out the risk factors of sepsis-induced CIP, especially its relationship with the severity of illness. PATIENTS AND METHODS: A cohort of 100 patients with sepsis defined as SIRS of proven or presumed microbial etiology were followed up with nerve conduction studies (NCS) performed within the first 14 days of admission...

BACKGROUND AND PURPOSE: There is increasing interest in using patient-reported outcome measures (PROMs) in clinical studies to capture individual changes over time. However, PROMs have also been criticized because they are entirely subjective. Our objective was to examine the relationship between a subjective PROM and an objective outcome tool in patients with Guillain-Barré syndrome (GBS), chronic inflammatory demyelinating polyradiculoneuropathy (CIDP) and gammopathy-related polyneuropathy (MGUSP)...

Survivorship after critical illness is an increasingly important health-care concern as ICU use continues to increase while ICU mortality is decreasing. Survivors of critical illness experience marked disability and impairments in physical and cognitive function that persist for years after their initial ICU stay. Newfound impairment is associated with increased health-care costs and use, reductions in health-related quality of life, and prolonged unemployment. Weakness, critical illness neuropathy and/or myopathy, and muscle atrophy are common in patients who are critically ill, with up to 80% of patients admitted to the ICU developing some form of neuromuscular dysfunction...

The hepatic porphyrias are a group of rare metabolic disorders, each of which is associated with a specific enzymatic alteration in the haem biosynthesis pathway. In South Africa (SA), a high incidence of variegate porphyria (VP) is seen as a result of a founder effect, but acute intermittent porphyria (AIP) is also encountered. The development of acute neurovisceral attacks is related to environmental factors, including medications, hormones and diet. A possible manifestation of a severe attack is rapidly progressing quadriparesis, which may mimic Guillain-Barré syndrome...

AIMS: Sepsis patients and other patients in the critical care settings are at very high risk of mortality due to the primary illness. However, a fraction of patients, even after showing initial clinical improvement, deteriorates relentlessly at later stages. Increasingly, it is being identified that this is mostly due to dysfunction of the neurological system. MAIN METHODS: We obtained peripheral nerve biopsies from the sural nerve from ICU patients. Nav1.6 expression was significantly diminished...

OBJECTIVE: ICU-acquired weakness, comprised critical illness myopathy and critical illness neuropathy, occurs in a significant proportion of critically ill adults and is associated with high morbidity and mortality. Little is known about ICU-acquired weakness among critically ill children. We investigated the incidence of ICU-acquired weakness among PICUs participating in the Virtual PICU Systems database. We also sought to identify associated risk factors for ICU-acquired weakness and evaluate the hypothesis that ICU-acquired weakness is associated with poor clinical outcomes...
