Influenza Cerebellitis in a 3-Year-Old Male.

Acute cerebellitis (AC) is often a para-infectious inflammatory process that usually presents with a variable clinical picture; often with fever, nausea, headache, altered mental status, gait abnormalities, and coordination defects. It is usually a complication of an infectious process or as a result of post-infectious autoimmune mechanisms. We report a case of a 3 year old male with influenza A who presented with an acute encephalitic picture whose course and radiologic studies demonstrate cerebellar changes strongly compatible with AC.

Smartphone Application Versus Standard Instruction for Colonoscopic Preparation: A Randomized Controlled Trial.

OBJECTIVE: To compare smartphone application (Colonoscopic Preparation) instructions versus paper instructions for bowel preparation for colonoscopy. BACKGROUND: Adhering to bowel preparation instructions is important to ensure a high-quality colonoscopy. PATIENTS AND METHODS: This randomized controlled trial included individuals undergoing colonoscopy at a tertiary care hospital. Individuals were randomized (1:1) to receive instructions through a smartphone application or traditional paper instructions. The primary outcome was the quality of the bowel preparation as measured by the Boston Bowel Preparation Score. Secondary outcomes included cecal intubation and polyp detection. Patient satisfaction was assessed using a previously developed questionnaire. RESULTS: A total of 238 individuals were randomized (n = 119 in each group), with 202 available for the intention-to-treat analysis (N = 97 in the app group and 105 in the paper group). The groups had similar demographics, indications for colonoscopy, and type of bowel preparation. The primary outcome (Boston Bowel Preparation Score) demonstrated no difference between groups (Colonoscopic Preparation app mean: 7.26 vs paper mean: 7.28, P = 0.91). There was no difference in cecal intubation (P = 0.37), at least one polyp detected (P = 0.43), or the mean number of polyps removed (P = 0.11). A higher proportion strongly agreed or agreed that they would use the smartphone app compared with paper instructions (89.4% vs 70.1%, P = 0.001). CONCLUSIONS: Smartphone instructions performed similarly to traditional paper instructions for those willing to use the application. Local patient preferences need to be considered before making changes in the method of delivery of medical instructions.

Health and Healthcare Disparities in Pediatric Epilepsy in the United States: A Scoping Review.

OBJECTIVES: Health disparities impact epilepsy care in children. Previous efforts to summarize data in this population have been limited. This study sought to understand how this information exists in the literature and identify gaps in knowledge. METHODS: A scoping review of peer-reviewed articles and gray literature was conducted using PRISMA guidelines. Disparity populations (e.g., Sex, Race/Ethnicity, Socioeconomic Status) and disparity outcomes (e.g., Quality of Life (QOL)/Psychological, Utilization, Mortality/Sudden Unexpected Death in Epilepsy) were identified. A finding was defined as a single result from a discrete statistical analysis of a specific clinical outcome by disparity population. Data extraction identified where this information existed in the literature and how it was reported. RESULTS: A total of 307 publications revealed 769 unique disparity/equity findings. Disparity populations were unequally represented (p < 0.0001). Sex and Race/Ethnicity had the most findings while Language/Immigration had the fewest. Nearly a quarter of findings (23%) addressed QOL/Psychological outcomes. The highest percentages of disparities were found in the Utilization, Mortality/SUDEP, and Economic categories. Of the 204 publications reporting disparity findings, fewer than half actually intended to investigate disparities as one of their original objectives. Of the disparity findings identified in peer-reviewed articles, a third were not mentioned in the abstract and 20% were not addressed in the discussion. INTERPRETATION: A comprehensive scoping review of health disparities in pediatric epilepsy found that specific disparity populations like Sex and Race/Ethnicity were robustly explored, while Language/Immigration was under-represented, despite a high rate of disparities. Health-related outcome categories were also unequally investigated. Disparity findings were often difficult to access within publications. ANN NEUROL 2024;95:733-742.

Diminished activity-dependent BDNF signaling differentially causes autism-like behavioral deficits in male and female mice.

Autism spectrum disorder (ASD) is a group of neurodevelopmental disorders with strong genetic heterogeneity and more prevalent in males than females. Recent human genetic studies have identified multiple high-risk genes for ASD, which produce similar phenotypes, indicating that diverse genetic factors converge to common molecular pathways. We and others have hypothesized that activity-dependent neural signaling is a convergent molecular pathway dysregulated in ASD. However, the causal link between diminished activity-dependent neural signaling and ASD remains unclear. Brain-derived neurotrophic factor (BDNF) is a key molecule mediating activity-dependent neural signaling. We therefore hypothesize that diminished activity-dependent BDNF signaling could confer autism-like behavioral deficits. Here, we investigated the effect of diminished activity-dependent BDNF signaling on autism-like behavioral deficits by using mice with genetic knock-in of a human BDNF methionine (Met) allele, which has decreased activity-dependent BDNF release without altering basal BDNF level. Compared with wild-type (WT) controls, diminished activity-dependent BDNF signaling similarly induced anxiety-like behaviors in male and female mice. Notably, diminished activity-dependent BDNF signaling differentially resulted in autism-like social deficits and increased self-grooming in male and female mice, and male mice were more severe than female mice. Again, sexually dimorphic spatial memory deficits were observed in female BDNF+/Met mice, but not in male BDNF+/Met mice. Our study not only reveals a causal link between diminished activity-dependent BDNF signaling and ASD-like behavioral deficits, but also identifies previously underappreciated sex-specific effect of diminished activity-dependent BDNF signaling in ASD. These mice with genetic knock-in of the human BDNF Met variant provide a distinct mouse model for studying the cellular and molecular mechanisms underlying diminished activity-dependent neural signaling, the common molecular pathway dysregulated in ASD.

A Randomized Controlled Pilot Study of Topical Ropivacaine for Prevention of Post-POEM Pain.

Background and Aims: Although usually mild to moderate in severity, postoperative pain after peroral endoscopic myotomy (POEM) is common. There are no studies that have addressed minimizing postoperative pain in patients undergoing POEM for achalasia. We hypothesized that intraoperative topical intra-tunnel irrigation with ropivacaine would result in a significant reduction in pain scores in the postoperative period. Methods: A double-blind, randomized, placebo-controlled trial was conducted at the Kingston Health Sciences Center. Patients received either 30 mL of 0.2% ropivacaine or 30 mL of placebo irrigated topically into the POEM tunnel after completing the myotomy and prior to closing the mucosal incision. The primary outcome was pain post-POEM at 6 h assessed by the Numeric Rating Scale (NRS). Secondary objectives included assessing pain score at 0.5, 1, 2, 4 h post-POEM and on discharge, Quality of Recovery (QoR-15) scores at discharge, narcotic requirement, adverse events, and patients' willingness to have the procedure done on an outpatient basis. Results: A total of 20 patients were enrolled. For the primary outcome of pain post-POEM at 6 h, the NRS was 1.1 in the placebo group and 2.4 in the ropivacaine group (95% CI of the difference: -3.2 to 0.6, P = 0.171). No statistical difference was seen in the pain scores. Overall usage of post-procedural narcotics was low with no differences between the two groups. Fifty percent of patients in both groups were willing to have the procedure done as an outpatient. Conclusion: The addition of intra-procedural tunnel irrigation with 30 mL 0.2% ropivacaine did not lead to reduced post-POEM pain.

Fistulotomy-First Approach is Safe and Effective in Endoscopic Retrograde Cholangiography: Results of a Prospective Case Series.

BACKGROUND AND AIMS: The aim of this study was to assess the safety and efficacy of using needle-knife fistulotomy (NKF) as a primary cannulation technique in patients undergoing endoscopic retrograde cholangiopancreatography (ERCP) with a native papilla. PATIENTS AND METHODS: This prospective feasibility study enrolled 50 patients between December 2018 and June 2019. The procedure was performed by two expert endoscopists (R.B. and L.H.). The primary outcome was the incidence of post-ERCP pancreatitis. Other variables assessed included the success rate of cannulation of the common bile duct (CBD), time to successful cannulation, and incidence of adverse events. RESULTS: Between December 2018 and June 2019, 50 patients enrolled in the study. The mean age was 63.4 years (standard deviation 18.1), and there were 26 females. Indications included biliary obstruction secondary to malignancy (n = 14) and choledocholithiasis (n = 36). Successful cannulation of the CBD through the fistulotomy occurred in 49/50 cases. The time to successful cannulation was 5.1 minutes (range 0.5 to 23 minutes). Mild acute pancreatitis occurred in two cases (4%). Post-ERCP bleeding occurred in three patients (6%). CONCLUSIONS: In this pilot study, NKF was used as the primary biliary access technique and it was demonstrated that it appears to be at least as safe as the traditional access technique with a sphinctertome. However, its role as a primary cannulation technique requires further investigation with multicenter, randomized control studies.

Emergency Department Management of Pediatric Unprovoked Seizures and Status Epilepticus in the State of Illinois.

The purpose of this survey and record review was to characterize emergency department management of unprovoked seizures and status epilepticus in children in Illinois. The survey was sent to 119 participating emergency departments in the Emergency Medical Services for Children program; responses were received from 103 (88% response rate). Only 44% of the emergency departments had a documented protocol for seizure management. Only 12% of emergency departments had child neurology consultation available at all times. Record review showed that 58% of patients were discharged home, 26% were transferred to another institution, and 10% were admitted to a non-intensive care unit setting. Ninety percent of patients were treated with anticonvulsants. Seizure education was provided by the primary emergency department nurse (97%) and the treating physician (79%). This project demonstrated strengths and weaknesses in the current management of pediatric seizure patients in Illinois emergency departments.

Perceptions and utilization of primary healthcare services in Iraq: findings from a national household survey.

BACKGROUND: After many years of sanctions and conflict, Iraq is rebuilding its health system, with a strong emphasis on the traditional hospital-based services. A network exists of public sector hospitals and clinics, as well as private clinics and a few private hospitals. Little data are available about the approximately 1400 Primary Health Care clinics (PHCCs) staffed with doctors. How do Iraqis utilize primary health care services? What are their preferences and perceptions of public primary health care clinics and private primary care services in general? How does household wealth affect choice of services METHODS: A 1256 household national survey was conducted in the catchment areas of randomly selected PHCCs in Iraq. A cluster of 10 households, beginning with a randomly selected start household, were interviewed in the service areas of seven public sector PHCC facilities in each of 17 of Iraq's 18 governorates. A questionnaire was developed using key informants. Teams of interviewers, including both males and females, were recruited and provided a week of training which included field practice. Teams then gathered data from households in the service areas of randomly selected clinics. RESULTS: Iraqi participants are generally satisfied with the quality of primary care services available both in the public and private sector. Private clinics are generally the most popular source of primary care, however the PHCCs are utilized more by poorer households. In spite of free services available at PHCCs many households expressed difficulty in affording health care, especially in the purchase of medications. There is no evidence of informal payments to secure health services in the public sector. CONCLUSIONS: There is widespread satisfaction reported with primary health care services, and levels did not differ appreciably between public and private sectors. The public sector PHCCs are preferentially used by poorer populations where they are important providers. PHCC services are indeed free, with little evidence of informal payments to providers.

Analysis of orotracheal intubation techniques in the intensive care unit.

BACKGROUND: The development of specialised airway tools help laryngoscopists secure the airway in intensive care units. The use of videolaryngoscopy has been suggested in simulation studies, and human studies suggest that this advanced airway tool may have an advantage for difficult airways; however, less is known about its use in the ICU. OBJECTIVE: To compare orotracheal intubation before and after acquisition of an ICU-dedicated GlideScope (GS), and to determine the incidence of complications with orotracheal intubation in an ICU. METHODS: An observational study was conducted from October 2008 to April 2009 to record the use of advanced airway tools including videolaryngoscopy before ("pre-GS") and immediately after ("post-GS") the purchase of an ICUdedicated videolaryngoscope. Reasons for intubation, response time, type of intubation, number of attempts at intubation, reasons for delays in intubation, risk factors for difficult intubation and complications were compared between these groups. RESULTS: 56 patients were intubated pre-GS and 47 post- GS. Although a significant increase in videolaryngoscopy was observed in the ICU (P = 0.001), no significant reduction in total attempts at orotracheal intubation were observed (P = 0.66), and that the incidence of overall complications were not reduced (P = 0.21). CONCLUSIONS: The use of a new airway tool may not necessarily lead to immediate reduction in attempts at orotracheal intubation or in overall complication rates.

Pediatric cuffed endotracheal tubes: an evolution of care.

PURPOSE: To examine the history of pediatric endotracheal intubation and the issues surrounding the change from uncuffed endotracheal tubes to cuffed endotracheal tubes, including pediatric airway anatomy, endotracheal tube design, complications, and safety concerns. METHOD: Review of the literature. CONCLUSIONS: Although the use of cuffed endotracheal tubes in infants and children remains a topic of debate, the literature supports this change in practice. Meticulous attention must be given to intracuff pressure. Cuffed endotracheal tubes designed especially for the pediatric patient may increase the margin of safety.

Effects of footwear on medial compartment knee osteoarthritis.

This pilot study investigated whether lateral-wedge insoles inserted into shock-absorbing walking shoes altered joint pain, stiffness, and physical function in patients with symptomatic medial compartment knee osteoarthritis (OA). Twenty-eight subjects wore full-length lateral-wedge insoles with an incline of 4 degrees in their walking shoes for 4 weeks. Pain, stiffness, and functional status were measured with the Western Ontario and McMaster Universities (WOMAC) Osteoarthritis Index at baseline and 4 weeks postintervention. Significant improvements were observed in all three WOMAC subscales (pain, stiffness, and function). Pain scores were significantly reduced for the most challenging activity-stair climbing. Subjects wore insoles daily and tolerated them well. The results of this study indicated that lateral-wedge insoles inserted into shock-absorbing walking shoes are an effective treatment for medial compartment knee OA.
