Body mass index in relation to symptom presentation on diagnosis of eosinophilic esophagitis in children.

BACKGROUND: The relationship between body mass index (BMI) and eosinophilic esophagitis (EoE) among children is not well characterized. OBJECTIVE: To evaluate the presentations of EoE in pediatric patients of different weight classes. METHODS: Records of newly diagnosed children with EoE at an academic center from 2015 to 2018 were evaluated regarding demographics, symptom presentation, and endoscopic findings and compared among the underweight, normal weight, overweight, and obese groups. RESULTS: There were 341 patients aged 0 to 18 years old newly diagnosed with EoE from 2015 to 2018 (68.3% male, 233 of 341; 80.9% White, 276 of 341). Of the 341, 17 were underweight (4.9%), 214 normal weight (62.8%), 47 overweight (13.8%), and 63 obese (18.5%). Children with obese and overweight BMI were more likely to be diagnosed at an older age (P = .005) and to present with a chief complaint of abdominal pain (P = .02). Normal- and under-weight children were more likely to have an immunoglobulin E-mediated food allergy (P = .02). Normal weight children were more likely to be tested for food allergies (P = .02) and inhalant allergies (P = .004) and have linear furrows on endoscopy (P = .03), compared with children with overweight and obese BMI. No significant differences were found regarding race, sex, type of insurance, atopic dermatitis, asthma, or allergic rhinitis in relation to BMI status and EoE diagnosis. CONCLUSION: Nearly one-third of children were obese or in overweight status on diagnosis with EoE. Children with BMI in the overweight or obese range were more likely to be older at diagnosis and to have a chief complaint of abdominal pain on presentation.

Impact of penicillin allergy labels among pneumonia admissions at an academic children's center.

Background: Pneumonia is the most common reason for pediatric hospitalizations. The impact of penicillin allergy labels among children with pneumonia has not been well studied. Objective: This study assessed the prevalence and impact of penicillin allergy labels among children admitted with pneumonia over a 3-year period at a large academic children's center. Methods: Inpatient charts of pneumonia admissions with a documented allergy to a type of penicillin from January to March in 2017, 2018, and 2019 were reviewed and compared with pneumonia admissions without the label over the same time with regard to days of antimicrobial treatment, route of antimicrobial therapy, and days of hospitalization. Results: There were 470 admissions for pneumonia during this time period, of which 48 patients (10.2%) carried a penicillin allergy label. Hives and/or swelling comprised 20.8% of the allergy labels. Other labels included nonpruritic rashes, gastrointestinal GI symptoms, unknown/undocumented reactions, or other reasons. There were no significant differences between those with a penicillin allergy label to those without regarding days of antimicrobial treatment (inpatient and outpatient), route of antimicrobial therapy, and days of hospitalization. Those with a penicillin allergy label were less likely to be prescribed a penicillin product (p < 0.002). Of the 48 patients who were allergy labeled, 23% (11/48) were given a penicillin medication without adverse reaction. Conclusion: Ten percent of pediatric admissions for pneumonia had a label of penicillin allergy, similar to the overall population. The hospital course and clinical outcome were not significantly affected by the penicillin allergy label. The majority of documented reactions were of low risk for immediate allergic reactions.

The Evolution of Clinical Trials in Renal Cell Carcinoma: A Status Report for 2013-2016 from the ClinicalTrials.gov Website.

BACKGROUND: We previously published an analysis of clinical trials in renal cell carcinoma (RCC) using the publicly available ClinicalTrials.gov registry. Here we present a 3-year update to understand clinical research current trends in RCC compared to 2013. METHODS: The Website's advanced search function was used to search for RCC trials. The characteristics of the trial were extracted, summarized and compared to 2013 data using Fisher's exact tests. RESULTS: We locked our search on May 26, 2016 with 165 trials eligible, compared with 169 trials on Sep 25, 2013. There were more phase I and I/II trials in 2016 compared to 2013 (40.8% vs 24.9%, p = 0.05). More clinical trials in 2016 compared to 2013 used immunotherapy (IT) alone or in combination with other drugs (24.2% vs 10.7%, p = 0.001), and the use of targeted therapy alone (TT) declined (32.9% vs 47.9%, p = 0.005). TT+IT combination trials more than doubled (6.7% vs 2.3%, p = 0.07). The number of trials with treatment in (neo)adjuvant settings in 2016 and 2013 were similar (9.7% vs 10.6%, p = 0.77), respectively. Compared to 2013, the number of trials with non-clear cell histology remained low (n = 10). Many more trials were sponsored by the pharmaceutical industry in 2016 vs 2013 (41.5% vs 16.0%, p = <0.001). CONCLUSION: IT-based and industry sponsored clinical trials significantly increased from 2013 to 2016 with a concomitant drop in TT only trials. The increase in industry-sponsored studies may reflect the rapid uptake of expensive IT drugs. There continues to be a paucity of (neo)adjuvant studies and for non-clear cell histologies.

Efficiency of spinal anesthesia versus general anesthesia for lumbar spinal surgery: a retrospective analysis of 544 patients.

BACKGROUND: Previous studies have shown varying results in selected outcomes when directly comparing spinal anesthesia to general in lumbar surgery. Some studies have shown reduced surgical time, postoperative pain, time in the postanesthesia care unit (PACU), incidence of urinary retention, postoperative nausea, and more favorable cost-effectiveness with spinal anesthesia. Despite these results, the current literature has also shown contradictory results in between-group comparisons. MATERIALS AND METHODS: A retrospective analysis was performed by querying the electronic medical record database for surgeries performed by a single surgeon between 2007 and 2011 using procedural codes 63030 for diskectomy and 63047 for laminectomy: 544 lumbar laminectomy and diskectomy surgeries were identified, with 183 undergoing general anesthesia and 361 undergoing spinal anesthesia (SA). Linear and multivariate regression analyses were performed to identify differences in blood loss, operative time, time from entering the operating room (OR) until incision, time from bandage placement to exiting the OR, total anesthesia time, PACU time, and total hospital stay. Secondary outcomes of interest included incidence of postoperative spinal hematoma and death, incidence of paraparesis, plegia, post-dural puncture headache, and paresthesia, among the SA patients. RESULTS: SA was associated with significantly lower operative time, blood loss, total anesthesia time, time from entering the OR until incision, time from bandage placement until exiting the OR, and total duration of hospital stay, but a longer stay in the PACU. The SA group experienced one spinal hematoma, which was evacuated without any long-term neurological deficits, and neither group experienced a death. The SA group had no episodes of paraparesis or plegia, post-dural puncture headaches, or episodes of persistent postoperative paresthesia or weakness. CONCLUSION: SA is effective for use in patients undergoing elective lumbar laminectomy and/or diskectomy spinal surgery, and was shown to be the more expedient anesthetic choice in the perioperative setting.
