BACKGROUND Delayed post hypoxic leukoencephalopathy syndrome(DPHLS),also known as Grinker’s myelinopathy,is a rare but significant neurological condition that manifests days to weeks after a hypoxic event.Characterized by delayed onset of neurological and cognitive deficits,DPHLS presents substantial diagnostic and therapeutic challenges.AIM To consolidate current knowledge on pathophysiology,clinical features,diagnostic approaches,and management strategies for DPHLS,providing a comprehensive overview and highlighting gaps for future research.METHODS Following the Preferred Reporting Items for Systematic Reviews and Meta-Analyzes guidelines,we systematically searched PubMed,ScienceDirect and Hinari databases using terms related to delayed post-hypoxic leukoencephalopathy.Inclusion criteria were original research articles,case reports,and case series involving human subjects with detailed clinical,neuroimaging,or pathological data on DPHLS.Data were extracted on study characteristics,participant demographics,clinical features,neuroimaging findings,pathological findings,treatment,and outcomes.The quality assessment was performed using the Joanna Briggs Institute critical appraisal checklist.RESULTS A total of 73 cases were reviewed.Common comorbidities included schizoaffective disorder,bipolar disorder,hypertension,and substance use disorder.The primary causes of hypoxia were benzodiazepine overdose,opioid overdose,polysubstance overdose,and carbon monoxide(CO)poisoning.Symptoms frequently include decreased level of consciousness,psychomotor agitation,cognitive decline,parkinsonism,and encephalopathy.Neuroimaging commonly revealed diffuse T2 hyperintensities in cerebral white matter,sometimes involving the basal ganglia and the globus pallidus.Magnetic resonance spectroscopy often showed decreased N-acetylaspartate,elevated choline,choline-to-creatinine ratio,and normal or elevated lactate.Treatment is often supportive,including amantadine,an antioxidant cocktail,and steroids.Hyperbaric oxygen therapy may be bene 展开更多

Knee dislocations frequently involve vascular injuries that demand early diagnosis and timely intervention. Time of ischemia is pivotal in determining the outcome for the limb, delays in treatment beyond 8 hours significantly increase the risk of limb loss. Unfortunately, this critical window is often missed in resource-limited settings. Here we report a 25-year-old female sustained a left knee injury after falling into a trench. She was diagnosed with an open knee dislocation accompanied by a popliteal artery injury. However, revascularization was delayed for 18 hours due to limited resources, including the unavailability of a thrombectomy catheter. Postoperatively, the patient received anticoagulation therapy with serial limb assessments and after 3 weeks the laceration healed and the limb was still viable. Knee dislocations frequently result in vascular injury (popliteal artery most common), making prompt diagnosis and intervention essential for limb preservation. In settings with limited resources, like ours, delayed presentation and transfer to specialized centers contribute to prolonged ischemic times. Nonetheless, viable limbs should be revascularized in stable patients, even with prolonged ischemia. This case highlights the importance of limb revascularization despite delay. Efforts should be made to improve prompt diagnosis, timely referral, and availability of necessary equipment for vascular repair to optimize outcomes in similar cases. 展开更多

Aneurysm rupture can result in subarachnoid hemorrhage,a condition with potentially severe consequences,such as disability and death.In the acute stage,early brain injury manifests as intracranial pressure elevation,global cerebral ischemia,acute hydrocephalus,and direct blood–brain contact due to aneurysm rupture.This may subsequently cause delayed cerebral infarction,often with cerebral vasospasm,significantly affecting patient outcomes.Chronic complications such as brain volume loss and chronic hydrocephalus can further impact outcomes.Investigating the mechanisms of subarachnoid hemorrhage-induced brain injury is paramount for identifying effective treatments.Stem cell therapy,with its multipotent differentiation capacity and anti-inflammatory effects,has emerged as a promising approach for treating previously deemed incurable conditions.This review focuses on the potential application of stem cells in subarachnoid hemorrhage pathology and explores their role in neurogenesis and as a therapeutic intervention in preclinical and clinical subarachnoid hemorrhage studies. 展开更多

Radiotherapy(RT)is the backbone of multimodality treatment of more than half of cancer cases.Despite new modern RT techniques,late complications may occur such as radiation proctitis(RP).The natural history of RP is unpredictable.Minor symptoms may resolve spontaneously or require conservative treatment.On the other hand,for similar and uncomplicated clinical contexts,symptoms may persist and can even be refractory to the progressive increase in treatment measures.Over the last decades,an enormous therapeutic armamentarium has been considered in RP,including hyperbaric oxygen therapy(HBOT).Currently,the evidence regarding the impact of HBOT on RP and its benefits is conflicting.Additional prospective and randomised studies are necessary to validate HBOT’s effectiveness in the‘real world’clinical practice.This article reviewed the relevant literature on pathophysiology,clinical presentation,different classifications and discuss RP management including a proposal for a therapeutic algorithm with a focus on HBOT. 展开更多

BACKGROUND The surgical management of bile duct injuries(BDIs)after laparoscopic cholecystectomy(LC)is challenging and the optimal timing of surgery remains unclear.The primary aim of this study was to systematically evaluate the evidence behind the timing of BDI repair after LC in the literature.AIM To assess timing of surgical repair of BDI and postoperative complications.METHODS The MEDLINE,EMBASE,and The Cochrane Library databases were systematically screened up to August 2021.Risk of bias was assessed via the Newcastle Ottawa scale.The primary outcomes of this review included the timing of BDI repair and postoperative complications.RESULTS A total of 439 abstracts were screened,and 24 studies were included with 15609 patients included in this review.Of the 5229 BDIs reported,4934(94%)were classified as major injury.Timing of bile duct repair was immediate(14%,n=705),early(28%,n=1367),delayed(28%,n=1367),or late(26%,n=1286).Standardization of definition for timing of repair was remarkably poor among studies.Definitions for immediate repair ranged from<24 h to 6 wk after LC while early repair ranged from<24 h to 12 wk.Likewise,delayed(>24 h to>12 wk after LC)and late repair(>6 wk after LC)showed a broad overlap.CONCLUSION The lack of standardization among studies precludes any conclusive recommendation on optimal timing of BDI repair after LC.This finding indicates an urgent need for a standardized reporting system of BDI repair. 展开更多

Motor endplates(MEPs) are important sites of information exchange between motor neurons and skeletal muscle, and are distributed in an organized pattern of lamellae in the muscle. Delayed repair of peripheral nerve injury typically results in unsatisfactory functional recovery because of MEP degeneration. In this study, the mouse tibial nerve was transected and repaired with a biodegradable chitin conduit, immediately following or 1 or 3 months after the injury. Fluorescent α-bungarotoxin was injected to label MEPs. Tissue optical clearing combined with light-sheet microscopy revealed that MEPs were distributed in an organized pattern of lamellae in skeletal muscle after delayed repair for 1 and 3 months. However, the total number of MEPs, the number of MEPs per lamellar cluster, and the maturation of single MEPs in gastrocnemius muscle gradually decreased with increasing denervation time. These findings suggest that delayed repair can restore the spatial distribution of MEPs, but it has an adverse effect on the homogeneity of MEPs in the lamellar clusters and the total number of MEPs in the target muscle. The study procedures were approved by the Animal Ethics Committee of the Peking University People's Hospital(approval No. 2019 PHC015) on April 8, 2019. 展开更多

Infusion of the colloid hydroxyethylstarch has been used for volume substitution to maintain hemodynamics and microcirculation after e.g., severe blood loss.In the last decade it was revealed that hydroxyethylstarch can aggravate acute kidney injury, especially in septic patients.Because of the serious risk for critically ill patients, the administration of hydroxyethylstarch was restricted for clinical use.Animal studies and recently published in vitro experiments showed that hydroxyethylstarch might exert protective effects on the blood-brain barrier.Since the prevention of blood-brain barrier disruption was shown to go along with the reduction of brain damage after several kinds of insults, we revisit the topic hydroxyethylstarch and discuss a possible niche for the application of hydroxyethylstarch in acute brain injury treatment. 展开更多

The structural damage to vascular endothelial cell In a recent article in the journal Brain Injury, four potential hypotheses for delayed neurological disorders following lightning and electrical injury were suggested (Reisner, 2013). The phenomenon of delayed neurodegenerative syndromes following lighting and electrical injury has been known since the early 1930s (Critchley, 1934), but to the present day, the mechanisms involved have been poorly un- derstood. An initial and still plausible theory is that the electrical insult causes damage to the vascular structures feeding the spinal cord via damage to vascular endothelial cells (Farrell and Starr, 1968). 展开更多

BACKGROUND Currently,open reduction internal fixation is the conventional surgical method for treatment of double ulna and radius fracture.However,open reduction is associated with a high risk of complications.This case of forearm double fracture involved a patient treated using an Acumed intramedullary nail.The patient experienced good follow-up outcomes.The Acumed forearm intramedullary nail enables early functional exercise and hastens healing of the fracture.Few studies have reported on the use of this approach for the treatment of fractures.CASE SUMMARY A 23-year-old male patient was admitted to hospital after 5 h of pain,swelling,and limited activity of left forearm caused by a careless fall.Physical examination showed stable basic vital signs,swelling of the left forearm,and severe pain when pressing on the injured part of the forearm.Further,friction was felt at the broken end of the bone;the skin was not punctured.Movement of the left hand was normal,and the left radial artery pulse was normal.Three-dimensional computed tomography examination showed an ulna fracture of the left forearm and comminuted fracture of the radius.The fracture was located in the upper third of the radius,with significant displacement on the fracture side.Clinical diagnosis further confirmed the left radius comminuted fracture and ulna fracture.After analyzing the fracture pattern,age,and other patient characteristics,we chose an Acumed nail for treatment and achieved good follow-up outcomes.CONCLUSION Acumed forearm intramedullary nail for fixation of ulna and radius fracture reduced complication risk and resulted in good follow-up outcomes. 展开更多
