Objective: To compare the dwell times of ultrasound-guided and non-ultrasound-guided short peripheral intravenous catheters in hospitalized children.
Methods: This was a retrospective analysis of data from 256 ultrasound-guided and 287 traditional peripheral intravenous catheters placed in hospitalized children between 1 September2016 and 31 October 2016 at a free-standing children's hospital with a 10-member vascular access team. A two-sample independent test and Kaplan-Meier estimator were used to assess differences in dwell times between the ultrasound-guided peripheral intravenous catheters and non-ultrasound-guided peripheral intravenous catheters. Child age, peripheral intravenous catheter location, and subjective difficulty of placement were also analyzed.
Results: There was a significant difference in mean hours of dwell time for ultrasound-guided versus non-ultrasound-guided peripheral intravenous catheters (96.06 vs 59.39, < 0.001). Mean increase in dwell time was 36.68 h (95% CI: [24.14-49.22]). Median dwell times (50% probability of survival) for ultrasound-guided and non-ultrasound-guided peripheral intravenous catheters were 118 h (95% CI: [95-137]) and 71 h (95% CI: [61-79]), respectively. None of the additional covariates were significant predictors of dwell time.
Conclusion: Peripheral intravenous catheters placed using ultrasound-guided methods had a significantly longer dwell time than those placed using non-ultrasound-guided methods in a cohort of hospitalized pediatric patients. This is in line with the findings in the adult literature and may suggest a need to increase the use of ultrasound-guided method for peripheral intravenous catheter placement in pediatric practice.

Background: Hereditary Sensory Motor Neuropathy (HSMN) 1A and Multiple Sclerosis (MS) are distinct demyelinating disorders affecting the peripheral and central nervous systems, respectively. We present a case of simultaneous occurrence of both conditions, exploring the clinical presentation, diagnostic workup, and potential interplay between these diseases. Case presentation and clinical approach: A 49-year-old male with a history of optic neuritis presented with progressive numbness, weakness, and sensory loss in all extremities over four years.

Chronic inflammatory demyelinating polyradiculoneuropathy (CIDP) includes a number of clinical subtypes. The major phenotype is "typical CIDP," which is characterized by symmetric and "proximal and distal" muscle weakness. Due to historical changes in the concept of CIDP, multifocal motor neuropathy, anti-myelin-associated glycoprotein (anti-MAG) neuropathy, and autoimmune nodopathy were excluded.

Guillain-Barre syndrome (GBS) is an autoimmune disorder affecting the peripheral nervous system, often triggered by infections. This important medical emergency can also have noninfectious causes, such as trauma, surgery, medication (including vaccinations), and other systemic disorders. Here, we present a rare case of GBS following a snakebite.

Rationale: Mutations in the leucine-rich repeat kinase 2 (LRRK2) gene play an important role in Parkinson's disease (PD) pathogenesis, and downregulation of LRRK2 has become a promising therapy for PD. Here, we developed a synthetic biology strategy for the self-assembly and delivery of small interfering RNAs (siRNAs) of LRRK2 into the substantia nigra via small extracellular vesicles (sEVs) using a genetic circuit (in the form of naked DNA plasmid) to attenuate PD-like phenotypes in mouse model.
Methods: We generated the genetic circuit encoding both a neuron-targeting rabies virus glycoprotein (RVG) tag and a LRRK2 siRNA under the control of a cytomegalovirus (CMV) promoter, and assessed its therapeutic effects using LRRK2 mouse models of PD.

Background: Timely vascular access forms a necessary part of patient management in the Emergency Department (ED). Factors such as hypotension, intravenous drug use, obesity, dark skin, patients at extremes of age, and patients with multiple injuries may make peripheral intravenous cannulation difficult. The intraosseous route remains a suitable alternative for emergency circulatory access.
