The primary objective was to evaluate hospital variation in intravenous (IV) acetaminophen use across pediatric patient populations. The secondary objective was to identify populations with high use of IV acetaminophen and wide variation in practice to identify priority areas for cost reduction and practice standardization.

We performed a retrospective study of children ≤18 years old hospitalized in 2019 in 48 US pediatric hospitals in the Pediatric Health Information System. Primary measures included IV acetaminophen use (percentage of encounters) and total days of therapy (DOT). A multivariable analysis identified clinical and demographic factors associated with IV acetaminophen use. High-priority groups for practice standardization were the All Patient Refined Diagnosis Related Groups in the top quartile of DOT, with wide variation of use across hospitals (interquartile range >50%).

Among 866 346 encounters, 14.4% received 1 dose of IV acetaminophen with 287 935 DOT, costing $29.8 million. In multivariable analysis age, payer, surgical procedure, ICU admission, total parenteral nutrition, and case mix index remained significantly associated with IV acetaminophen use. After multivariable adjustment, variation in hospital use ranged from <0.1% to 31% of all encounters. Twenty diagnosis groups accounted for 47% of total DOT (135 910 days) and 48% of cost ($14.2 million). Appendectomy, tonsil and adenoidectomy, and craniotomy were identified as top candidates for standardization efforts.

We observed large variation in IV acetaminophen use across pediatric hospitals and within diagnosis groups. These diagnoses represent candidates for practice standardization.

To assess the prevalence of antiplexin D1 antibodies (plexin D1-immunoglobulin G [IgG]) in small fiber neuropathy (SFN) and the effects of these antibodies in vivo.

We developed an ELISA for plexin D1-IgG using a recombinant extracellular domain of human plexin D1 containing the major epitope and sera from 58 subjects previously studied with a standard tissue-based indirect immunofluorescence assay (TBA). We screened 63 patients with probable SFN and 55 healthy controls (HCs) for serum plexin D1-IgG using ELISA. The results were confirmed by TBA. IgG from 3 plexin D1-IgG-positive patients, 2 plexin D1-IgG-negative inflammatory disease controls, and 2 HCs was intrathecally injected into mice, which were assessed for mechanical and thermal hypersensitivity 24 and 48 hours after injection.

The ELISA had 75% sensitivity and 100% specificity using the TBA as a standard, and the coincidence rate of ELISA to TBA was 96.6% (56/58). The frequency of plexin D1-IgG was higher in patients with SFN than in HCs (12.7% [8/63] vs 0.0% [0/55],

= 0.007). Purified IgG from all 3 plexin D1-IgG-positive patients, but not 2 plexin D1-IgG-negative patients, induced significant mechanical and/or thermal hypersensitivity compared with IgG from HCs. In mice injected with plexin D1-IgG-positive but not D1-IgG-negative patient IgG, phosphorylated extracellular signal-regulated protein kinase immunoreactivity, an activation marker, was confined to small dorsal root ganglion neurons and was significantly more abundant than in mice injected with HC IgG.

Plexin D1-IgG is pathogenic but with low prevalence and is a potential biomarker for immunotherapy in SFN.

E-scooters have emerged as a frequently used vehicle in German cities due to their high availability and easy access. However, investigations about the causes and mechanisms of E-scooter incidents and their trauma-specific consequences are rare.

We analysed all patients involved in E-scooter incidents from June to December 2019 who presented to four inner-city EDs in Berlin. The prospective data included patient-related and incident-related data, information on injury patterns and therapy, responses in a voluntary questionnaire concerning E-scooter use and general traffic experience.

248 patients (129 males; median age 29 years (5-81)) were included 41% were tourists and 4% were children. Most incidents (71%) occurred between July and September 2019, the majority occurring at weekends (58%). The injury pattern was mostly multifocal, affecting the lower (42%) and upper limbs (37%) and the head (40%). Traumatic brain injury was associated with alcohol consumption. Inpatient admission was recorded in 25%, surgery in 23%.

This study has defined the incidence of injury related to E-scooter use in a major European city. Stricter laws governing the use of E-scooters, the wearing of helmets and technical modifications to the E-scooter platforms might decrease E-scooter-associated incidents and resulting injuries in the future.

If approved, 177Lu-PSMA-617 would be the first targeted radiopharmaceutical available for treating a common solid tumor, and the first therapy directed at PSMA.Immune checkpoint blockade (ICB) has revolutionized cancer therapy. However, the response of patients to ICB is difficult to predict. Here, we examined 81 lung cancer patients under ICB treatment and found that patients with MET amplification were resistant to ICB and had a poor progress-free survival. Tumors with MET amplifications had significantly decreased STING levels and antitumor T cell infiltration. Furthermore, we performed deep single-cell RNA sequencing on more than 20000 single immune cells and identified an immunosuppressive signature with increased subsets of XIST- and CD96-positive exhausted NK cells and decreased CD8+ T cell and NK cell populations in patients with MET-amplification. Mechanistically, we found that oncogenic MET signaling induces phosphorylation of UPF1 and downregulates tumor cell STING expression via modulation of the 3'-UTR length of STING by UPF1. Decreased efficiency of ICB by MET amplification can be overcome by inhibiting MET.A late preterm infant was born to a diabetic mother on a background of reduced fetal movements and a poor CTG. It was noted immediately at birth that there was pathology in both upper limbs. Targeted investigation led to the diagnosis of bilateral upper limb arterial thromboses. Prompt assessment and multidisciplinary discussion led to an individualised management plan resulting in a positive outcome.We describe a cluster of six SARS-CoV-2 infections occurring in a crowded neonatal unit in Botswana, including presumed transmission among mothers, postnatal mother-to-neonate transmission and three neonate-to-healthcare worker transmissions. The affected neonate, born at 25 weeks' gestation weighing 785 g, had a positive SARS-CoV-2 test at 3 weeks of age which coincided with new onset of hypoxaemia and worsening respiratory distress. Because no isolation facility could accommodate both patient and mother, they were separated for 10 days, during which time the patient was switched from breastmilk to formula. Her subsequent clinical course was marked by several weeks of supplemental oxygen, sepsis-like presentations requiring additional antibiotics and bronchopulmonary dysplasia. Despite these complications, adequate growth was achieved likely due to early initiation of nutrition. This nosocomial cluster highlights the vulnerabilities of neonates, caregivers and healthcare workers in an overcrowded environment, and underscores the importance of uninterrupted bonding and breast feeding, even during a pandemic.An 85-year-old man with a known history of abdominal aortic aneurysm (AAA) presented to a vascular surgery clinic with a severely swollen, tender and erythematous left leg. An urgent CT angiogram demonstrated a left-sided, proximal deep vein thrombosis, and a permanent, Bird's Nest inferior vena cava (IVC) filter (Cook, Inc., Bloomington, Ind.) penetrating his AAA. The patient was treated with a course of apixaban 5 mg two times per day and the decision was made to closely observe his IVC filter and AAA, given his numerous comorbidities and age. This case highlights the unique considerations associated with an approach to permanent IVC filter complications among patients with AAAs.Human T-lymphotropic virus type I (HTLV-I) is a retrovirus associated with adult T-cell lymphoma (ATL) and HTLV-I-associated myelopathy/tropical spastic paraparesis (HAM/TSP). In addition to HAM/TSP and ATL, HTLV-I-associated encephalopathy and cerebellar involvement have been reported. We report a case of an 87-year-old Japanese woman presenting with progressive dysarthria and gait disturbance. Neurological examination showed word-finding difficulty, scanning speech, saccadic eye movements, ocular dysmetria, gaze-evoked nystagmus and bilateral dysmetria. There was no motor weakness or spasticity. HTLV-I antibody was detected in both her serum and cerebrospinal fluid. Cerebrospinal fluid neopterin (57 pg/mL) and IgG index (3.27) were significantly elevated. MRI showed cerebellar swelling. She was finally diagnosed with HTLV-I associated cerebellitis. Two courses of high-dose intravenous methylpredonine therapy attenuated cerebellar ataxia and cerebellar swelling. It suggests that cerebellitis can result from HTLV-I infection, regardless of the existence of ATL or HAM/TSP.Partial or complete spontaneous regression (SR) of cancer is unusual, particularly in patients with oesophageal cancer. This case report describes a patient with biopsy-proven squamous cell carcinoma of the oesophagus which spontaneously regressed without any treatment. Regression of the primary tumour was confirmed on histological examination of the resected specimen. The process of SR remains an enigma, but potential mechanisms are considered.Vascularised epiphysial fibula bone transfers in the paediatric population provides a solution to growth suppression in extremity reconstruction. We report a case of an anatomical variant to the epiphysial blood supply that has never been reported in literature. A 6-year-old girl underwent a free vascularised fibula flap for reconstruction of her right humerous following osteosarcoma resection. While identifying and dissecting the recurrent epiphysial branch, a large branch from the peroneal artery was identified which directly entered the head of the fibula. No dominant supply from the anterior tibial (AT) vessels to the head of the fibula was seen. This led to the need for a bipedicled flap with diaphyseal supply from the AT vessels and the epiphysial transfer based on the peroneal artery. The patient made an uneventful recovery from the procedure. The same technique may be used by surgeons that may encounter this unique variant in clinical practice.
