Comprehensive assessment and progression of health status during neurorehabilitation in survivors of critical illness: a prospective cohort study.

Background: Critical illness survivors frequently suffer from long-term impairments, often described as post-intensive care syndrome (PICS). PICS encompasses physical, cognitive, and mental impairments. Additionally, the term intensive care unit (ICU)-acquired weakness (ICUAW) was coined for muscle weakness after critical illness.

Case report: Fatal Borna virus encephalitis manifesting with basal brain and brainstem symptoms.

Background: Since the first report of fatal Borna virus-1 (BoDV-1) encephalitis in 2018, cases gradually increased. There is a lack of diagnostic algorithm, and there is no effective treatment so far.

Case Presentation: We report an acute BoDV-1 encephalitis in a 77-year-old female with flu-like onset, rapid progression to word-finding difficulties, personality changes, global disorientation, diffuse cognitive slowness, and gait ataxia and further deterioration with fever, meningism, severe hyponatremia, epileptic seizures, cognitive decline, and focal cortical and cerebellar symptoms/signs.

Balanced volatile sedation with isoflurane in critically ill patients with aneurysmal subarachnoid hemorrhage - a retrospective observational study.

Introduction: In patients with severe aneurysmal subarachnoid hemorrhage (SAH) deep sedation is often used early in the course of the disease in order to control brain edema formation and thus intracranial hypertension. However, some patients do not reach an adequate sedation depth despite high doses of common intravenous sedatives. Balanced sedation protocols incorporating low-dose volatile isoflurane administration might improve insufficient sedation depth in these patients.

Critical COVID-19 disease: Clinical course and rehabilitation of neurological deficits.

Background: The COVID-19 disease frequently causes neurological symptoms. Critically ill patients often require neurorehabilitation for manifestations like intensive care unit (ICU) acquired weakness or encephalopathy. The outcome of these patients, however, is largely unknown.

The serotonin receptor 2A (HTR2A) rs6313 variant is associated with higher ongoing pain and signs of central sensitization in neuropathic pain patients.

Background: The serotonin receptor 2A (HTR2A) has been described as an important facilitation mediator of spinal nociceptive processing leading to central sensitization (CS) in animal models of chronic pain. However, whether HTR2A single nucleotide variants (SNVs) modulate neuropathic pain states in patients has not been investigated so far. The aim of this study was to elucidate the potential association of HTR2A variants with sensory abnormalities or ongoing pain in neuropathic pain patients.

Perioperative Management of a Patient with Severe Factor V Deficiency Presenting with Chronic Subdural Hematoma: A Clinical Report.

Background: Severe factor V deficiency is an extremely rare coagulation disorder. Patients with factor V activity <5% usually become symptomatic in early childhood.

Case Description: We report the case of an 82-year-old woman with incidentally diagnosed severe factor V deficiency, who developed a symptomatic chronic subdural hematoma, requiring burr hole craniostomy.

CSF penetration of vancomycin in critical care patients with proven or suspected ventriculitis: a prospective observational study.

Background: Vancomycin is recommended for ventriculitis. However, penetration into the CNS is relatively poor.

Objectives: To investigate the population pharmacokinetics of vancomycin in serum and CSF in critical care patients with proven or suspected CNS infections from neurosurgical procedures.

Role of Cerebrospinal Fluid Markers for Predicting Shunt-Dependent Hydrocephalus in Patients with Subarachnoid Hemorrhage and External Ventricular Drain Placement.

Objective: We sought to identify potential risk factors for the development of shunt-dependent chronic hydrocephalus after aneurysmal subarachnoid hemorrhage (SAH) and external ventricular drain (EVD) insertion. In particular, the role of inflammatory markers within the cerebrospinal fluid (CSF) was assessed.

Methods: For this single-center analysis, data were generated from consecutive patients with SAH and the need for EVD implantation treated on our neurosurgical intensive care unit between 2013 and 2015.

Low-Dose versus Therapeutic Range Intravenous Unfractionated Heparin Prophylaxis in the Treatment of Patients with Severe Aneurysmal Subarachnoid Hemorrhage After Aneurysm Occlusion.

Background: While prophylaxis with intravenous unfractionated heparin (UFH) can effectively prevent venous thromboembolism (VTE) during the neurocritical care of patients with severe aneurysmal subarachnoid hemorrhage (aSAH), the risk for intracranial bleeding complications might increase. Owing to this therapeutic dilemma, the UFH administration regimen in this critical patient population remains highly controversial.

Methods: We performed a retrospective analysis of patients with severe aSAH (Fisher grade 3-4) receiving either low-dose (activated partial thromboplastin time [aPTT] <40 seconds) or therapeutic range (aPTT 50-60 seconds) UFH during intensive care unit (ICU) treatment after complete surgical/endovascular aneurysm occlusion.

Inflammatory Markers in Serum and Cerebrospinal Fluid for Early Detection of External Ventricular Drain-associated Ventriculitis in Patients With Subarachnoid Hemorrhage.

Background: External ventricular drain (EVD)-associated ventriculitis is a serious complication. Early diagnosis can be difficult particularly in critically ill patients with aneurysmal subarachnoid hemorrhage (aSAH). We examined the diagnostic potential of standard serum and cerebrospinal fluid (CSF) biomarkers to differentiate between EVD-associated infections and aseptic courses in patients with aSAH.

[Prolonged weaning during early neurological and neurosurgical rehabilitation : S2k guideline published by the Weaning Committee of the German Neurorehabilitation Society (DGNR)].

Prolonged weaning of patients with neurological or neurosurgery disorders is associated with specific characteristics, which are taken into account by the German Society for Neurorehabilitation (DGNR) in its own guideline. The current S2k guideline of the German Society for Pneumology and Respiratory Medicine is referred to explicitly with regard to definitions (e.g.

Interleukin 6 in the Cerebrospinal Fluid as a Biomarker for Onset of Vasospasm and Ventriculitis After Severe Subarachnoid Hemorrhage.

Objective: The aim of the study was to investigate the diagnostic potential of interleukin 6 (IL-6) and other soluble biomarkers in serum and cerebrospinal fluid (CSF) for early diagnosis of cerebral vasospasm (cVS) and external ventricular drain-associated ventriculitis (VC) and to separate these conditions from aneurysmal subarachnoid hemorrhage (aSAH) without further complication (SAH).

Methods: The concentrations of serum biomarkers and markers in the CSF were collected in 63 consecutive patients with aSAH and external ventricular drainage. Arithmetical means and standard deviations, area under the curve (AUC), cutoff values (C-OFF), sensitivity (SE), and specificity (SP) were calculated for markers and their correlation with SAH, cVS, and VC.

Cerebrospinal fluid penetration of meropenem in neurocritical care patients with proven or suspected ventriculitis: a prospective observational study.

Background: Ventriculitis is a complication of temporary intraventricular drains. The limited penetration of meropenem into the cerebrospinal fluid (CSF) is well known. However, ventricular CSF pharmacokinetic data in patients with ventriculitis are lacking.

[Critical care management of intracerebral hemorrhage].

Background: Intracerebral hemorrhage accounts for up to 20 % percent of all ischemic strokes. In addition to a higher mortality, they are often associated with severe neurological impairment for those affected.

Objectives: Review of the current literature and guidelines addressing the critical care management of spontaneous intracerebral hemorrhage, including treatments to reduce primary and secondary neurological damage.

Decreased Linezolid Serum Concentrations in Three Critically Ill Patients: Clinical Case Studies of a Potential Drug Interaction between Linezolid and Rifampicin.

Linezolid is a valuable treatment option for treating infections caused by multi-resistant gram-positive pathogens. Lack of effective linezolid levels due to the co-administration of rifampicin has been described in healthy subjects. However, the clinical significance of this potential drug interaction (DI) for critically ill patients is still unclear.

[Acute non-allergic angioedema. Rare cause for intensive care unit admission].

Angiotensin-converting enzyme (ACE) inhibitor-induced angioedema usually follows an uneventful clinical course; however, if upper airway structures are involved, life-threatening complications may develop. Thus, affected patients should be carefully monitored in an intensive care unit and, if need be, the airway has to be secured early on. This case report discusses diagnostic and therapeutic approaches in a patient with suspected ACE inhibitor-induced angioedema, who had initially been admitted for neoadjuvant radiochemotherapy of rectal cancer.

The major brain endocannabinoid 2-AG controls neuropathic pain and mechanical hyperalgesia in patients with neuromyelitis optica.

Recurrent myelitis is one of the predominant characteristics in patients with neuromyelitis optica (NMO). While paresis, visual loss, sensory deficits, and bladder dysfunction are well known symptoms in NMO patients, pain has been recognized only recently as another key symptom of the disease. Although spinal cord inflammation is a defining aspect of neuromyelitis, there is an almost complete lack of data on altered somatosensory function, including pain.

Survival after cardiac arrest and changing task profile of the cardiac arrest team in a tertiary care center.

Background: The characteristics of in-hospital emergency response systems, survival rates, and variables associated with survival after in-hospital cardiac arrest vary significantly among medical centers worldwide. Aiming to optimize in-hospital emergency response, we performed an analysis of survival after in-hospital cardiopulmonary resuscitation and the task profile of our cardiac arrest team.

Methods: In-hospital emergencies handled by the cardiac arrest team in the years 2004 to 2006 were analyzed retrospectively, and patient and event characteristics were tested for their associations with survival after cardiopulmonary resuscitation.

[Unusual intensive care course in a patient with head injuries].

This article reports the case of a patient who developed a sudden impairment of gas exchange, renal function and a distended abdomen 13 days after admission to the intensive care unit. The combination of a sudden platelet drop, the timing of heparin administration and evidence of thromboembolic events by computed tomography (CT) led to the suspected diagnosis of heparin-induced thrombocytopenia (HIT) type II which was confirmed by laboratory testing. HIT is a life-threatening complication of heparin anticoagulation and CT is an important diagnostic instrument for detecting the location and extent of thromboembolic manifestations, thereby enabling the initiation of therapy to prevent further complications.

Sensory signs in complex regional pain syndrome and peripheral nerve injury.

This study determined patterns of sensory signs in complex regional pain syndrome (CRPS) type I and II and peripheral nerve injury (PNI). Patients with upper-limb CRPS-I (n=298), CRPS-II (n=46), and PNI (n=72) were examined with quantitative sensory testing according to the protocol of the German Research Network on Neuropathic Pain. The majority of patients (66%-69%) exhibited a combination of sensory loss and gain.

Complex interaction of sensory and motor signs and symptoms in chronic CRPS.

Spontaneous pain, hyperalgesia as well as sensory abnormalities, autonomic, trophic, and motor disturbances are key features of Complex Regional Pain Syndrome (CRPS). This study was conceived to comprehensively characterize the interaction of these symptoms in 118 patients with chronic upper limb CRPS (duration of disease: 43±23 months). Disease-related stress, depression, and the degree of accompanying motor disability were likewise assessed.

Transient receptor potential channel polymorphisms are associated with the somatosensory function in neuropathic pain patients.

Transient receptor potential channels are important mediators of thermal and mechanical stimuli and play an important role in neuropathic pain. The contribution of hereditary variants in the genes of transient receptor potential channels to neuropathic pain is unknown. We investigated the frequency of transient receptor potential ankyrin 1, transient receptor potential melastin 8 and transient receptor potential vanilloid 1 single nucleotide polymorphisms and their impact on somatosensory abnormalities in neuropathic pain patients.

[Amitriptyline-induced cardiac arrest : treatment with fat emulsion].

A case of successful resuscitation of a patient with severe amitriptyline intoxication is reported. The measured amitriptyline serum levels far exceeded those assumed to be lethal according to the literature. Resuscitation was successful with the administration of intravenous fat emulsion and the patient recovered without any neurological sequelae.
