0.006). There was no correlation between confidence and the number of umbilical lines placed on live subjects. Conclusion A teaching strategy that allows pediatric residents to struggle to perform UVC placement in a simulated setting, before receiving expert instruction, is effective at increasing their confidence and competence, even in the absence of exposure to human subjects.Coronavirus disease 2019 (COVID-19) is caused by severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) and has become a global pandemic. This disease has been shown to affect various organ systems, including the cerebrovascular system with sequelae still not completely uncovered. We present an unusual case of extensive brainstem intraparenchymal hemorrhage in a patient with COVID-19 to caution readers of this possible complication in patients positive for COVID-19. In this report, we outline the clinical presentation of a 40-year-old male who developed severe coughing and sneezing before presenting to the emergency department with confusion, somnolence, and respiratory distress. CT head without contrast revealed extensive pontine and midbrain hemorrhage with intraventricular extension and early hydrocephalus. Neurological examination revealed pinpoint, minimally reactive pupils, withdrawal to painful stimuli in the right hemibody, left hemibody paresis, and intact left corneal, cough, and gag reflexes. MRI and MRA brain revealed no evidence of an underlying vascular lesion. Over the next two days, the patient had worsening multiorgan failure and hypoxemia without intracranial hypertension. He remained too unstable to undergo cerebral angiogram. On hospital day four, his neurological examination deteriorated to quadriparesis and only cough and gag reflexes remaining intact after which his family opted for comfort measures only. In summary, a potential increased risk of intracerebral hemorrhage adds to the complexity of management of patients with COVID-19. This is especially true in those who have violent sneezing or coughing, or those who are on anticoagulation or antiplatelet therapy.Background and purpose Recently published HyTEC report summarized lung toxicity data and proposed guidelines of mean lung dose (MLD) less then 8 Gy and normal lung receiving at least 20 Gy, V20Gy less then 10-15% to avoid lung toxicity. Support for preferred use of a particular dosimetric parameter has been limited. We performed a detailed dose-volume analysis of data on radiation pneumonitis (RP) following lung stereotactic body radiation therapy (SBRT) to search for parameters showing the strongest correlation with RP. Materials and methods Two patient cohorts (primary and metastatic lung tumor patients) from previously reported studies were analyzed. Total number of patients was 96, and incidence of grade ≥2 RP was 13.5% (13/96). Fitting to the logistic function was performed to investigate correlation between incidence of RP and reported dosimetric and volumetric parameters. Another independent cohort was used to explore correlation between dosimetric parameters. selleck compound Results Among normal lung parameters (MLD and reported Vx), only MLD consistently showed significant correlation with incidence of RP. Gross tumor volume (GTV), internal target volume, planning target volume (PTV), and minimum dose covering 95% of GTV or PTV did not show statistical significance. A significant correlation between reported Vx and MLD was observed in all cohorts. Conclusions In considering tumor- and target-specific (e.g., GTV, PTV) and normal lung-specific (e.g., MLD, Vx) metrics, MLD was the only parameter that consistently correlated with incidence of RP across both cohorts. Because SBRT planning constraints allow small normal lung volumes to receive high doses, utility of MLD is not obvious. The parallel structure of lung is one possible explanation, but correlation between dosimetric parameters obscures elucidation of the preferred or mechanistically based parameter to guide radiotherapy planning.The most well-known type of cardiovascular arrhythmia in the United States and worldwide is atrial fibrillation (AF). Generally, 2.3 million individuals are determined to have AF in the United States. Energy drinks contain caffeine, taurine, theophylline, and sugars that enhance alertness. Consumption of energy drinks is mounting in the young population and has been associated with AF, regardless of the lack of conclusive evidence in the literature. This is a case report of a 22-year-old male without any significant cardiac history who was diagnosed with AF following intake of energy drinks.Catheter erosion into the small bowel is an uncommonly reported complication of continuous ambulatory peritoneal dialysis (CAPD). This can result in peritonitis, sepsis, fistula formation, and mortality. We report a 29-year-old female with end-stage renal disease presenting with nausea, profuse diarrhea immediately after dialysate instillation, change in color and odor of the dialysis output, and pain at the site of her peritoneal dialysis (PD) catheter. After a thorough evaluation, catheter tip erosion into the patient's small bowel lumen was diagnosed. This was confirmed when a blue bowel movement followed instillation of a saline solution with methylene blue into the dialysis catheter. A laparoscopic-assisted procedure was performed with removal of the dialysis catheter, resection of the diseased small bowel, and insertion of a right internal jugular tunneled dialysis catheter. Small bowel biopsy was benign. Post-operatively, the patient had no complications, was started on hemodialysis, and was discharged home.Toxic leukoencephalopathy is a rare cause of encephalopathy. We describe two cases of toxic leukoencephalopathy associated with opiate abuse where they were misdiagnosed and admitted to the psychiatric ward. In our case series, both patients presented with behavioral changes, restlessness, pressured speech, and cognitive impairment for which they were initially labeled as psychiatric patients and were treated as such. However, after an extensive workup to elucidate the etiology of alteration in mental status, toxic leukoencephalopathy associated with heroin abuse was found to be the culprit in both cases. Toxic leukoencephalopathy is a rare condition that can be caused by inhalation of heroin. Clinically, it may present with confusion, behavioral changes, extrapyramidal symptoms, generalized motor deficit, unresponsiveness and even death. Our cases highlight the importance of recognizing the psychiatric presentation of toxic leukoencephalopathy.
