Abstract Objective Parenchymal breast cysts are considered to be rare in men and are sparsely described in the literature. The purpose of this study was to review our institution’s experience with male breast cysts in an effort to improve overall understanding and management of this rare entity. Methods An institutional review board–exempt retrospective study was performed. Radiology reports for males who underwent mammogram and/or breast ultrasound at any of our institution’s primary or satellite locations from January 1995 to January 2020 were screened to find males with breast cysts. If cysts were reported and images were available, case review was performed to confirm parenchymal breast cyst(s) and patient characteristics were collated. Results Of 5425 male cases presenting for breast imaging, 19 (0.4%) cases of male breast cysts were confirmed, with a mean patient age of 41.6 years (range: 2–81 years). The most common indication leading to cyst discovery was a palpable lump, corresponding to the site of the cyst in 5 (26.3%) patients and near the site where cyst(s) were ultimately discovered in 7 (36.8%) patients. There were 8 (42.1%) instances of cysts without concurrent gynecomastia. Three (15.8%) men underwent needle sampling. There were no cases of atypia or malignancy on needle biopsy or on subsequent clinical follow-up, with median clinical follow-up of 70.3 months (range: 3.3–259.4 months). Conclusion Male breast parenchymal cysts are rare, but their prevalence is likely underestimated. If detected incidentally or upon targeted evaluation, biopsy may be averted if classic benign cyst features are identified.

Objectives This study was designed to: (1) characterize stay duration following cesarean delivery, (2) ascertain whether facility variation exists, and (3) determine whether shorter stays are associated with rates of readmission or costs. Study Design The 2017 Nationwide Readmissions Database was used to identify uncomplicated cesarean deliveries. Hierarchical logistic regression was used to assess for facility variation in percentage of patients discharged within 2 days. Similar models were used to assess for associations between probability of readmission within 30 days and facility-level rates of discharge within 2 days. Results In total, 456,312 patients from 1,535 hospitals were included. The median facility discharged 46.8% of patients within 2 days, with the 25th percentile of hospitals 23.7% and the 75th percentile 71.2%. In adjusted regression, there was significant facility heterogeneity (p < 0.0001). The overall readmission rate was 1.7%, and proportion of patients discharged within 2 days of cesarean delivery was not associated with readmission probability (adjusted relative risk: 1.02, confidence interval: 0.90–1.16), but was associated with lower inpatient costs (adjusted incremental cost: $111, confidence interval: −181 to −41). Conclusion Unexplained facility variation in percentage of patients discharged within 2 days of cesarean delivery was not associated with differences in readmissions. Key Points

With the increased use of CT, discovering incidental pancreatic lesions has become commonplace. Lesions in the distal pancreas lend themselves well to laparoscopic resection. We reviewed our experience with laparoscopic distal pancreatectomy. During the study period, 32 distal pancreatectomies were performed. There were 20 females. Mean patient age was 58.0 years (range, 23–83 years) and mean body mass index was 29.9 kg/m 2 (range, 19.9–44.7 kg/m 2 ). Technique was laparoscopic (25) or hand-assisted (seven) with one conversion in each group. The spleen was preserved in six patients (18.8%). Mean operative time overall was 238 minutes (range, 140–515 minutes); hand-assisted was 222 minutes and laparoscopic was 254 minutes. Estimated blood loss averaged 221 mL (range, 50–1800 mL). Mean tumor size was 2.7 cm (range, 0.6–7 cm). Tumor pathology was serous cystadenoma (10), neuroendocrine tumor (six), mucinous cystic neoplasm (four), intrapapillary mucinous neoplasm (four), adenocarcinoma (three), other (four), and solid pseudopapillary neoplasm (one). Mean length of stay was 5 days (range, 3–11 days). Complications were pancreatic fistula (six), wound infection (two), pulmonary embolism (one), pancreatitis (one), myocardial infarction (one), postoperative bleed from combined laparoscopic bilateral oophorectomy (one), and pancreatic stump staple line bleed requiring reoperation (one). There were no perioperative deaths. All pancreatic fistulas resolved with conservative management.

Abstract Background We sought to compare the dysplasia detection rate of high-definition white light endoscopy (HDWLE) with that of chromoendoscopy in patients with long-standing inflammatory bowel disease (IBD). Methods This is a retrospective observational cohort of patients with IBD who underwent surveillance colonoscopy between October 1, 2016 and September 30, 2017. We assessed the association between dysplasia detection and multiple variables. Results A total of 808 unique colonoscopies were performed, of which 150 (18.6%) included chromoendoscopy. Primary sclerosing cholangitis was a comorbid diagnosis in 24.5% of patients. The performing endoscopist was an IBD specialist with 37.1% of patients and had &gt;10 years’ experience with 64.9% of patients. Prior dysplasia had been seen in 245 (30.3%) patients: 102 (68.0%) and 143 (22.0%) among patients who had chromoendoscopy and HDWLE, respectively. Dysplasia in polyps was found in 129 procedures (15.1%). Among patients who had chromoendoscopy and HDWLE, polypoid dysplasia was identified in 50 (33.0%) and 79 (12.0%) patients, respectively, P &lt; 0.01. Dysplasia in random biopsies was found in 39 patients (4.8%): 15 (10%) who had chromoendoscopy and 24 (3.6%) who had HDWLE (P &lt; 0.001). On multivariate analysis, patient and disease characteristics significantly associated with an increased odds for polypoid dysplasia included older age at diagnosis (odds ratio [OR] = 1.3 per 10 years; 95% confidence interval [CI], 1.07-1.60), having an IBD physician endoscopist (OR = 1.6; 95% CI, 1.01-2.67), having an endoscopist with less than 10 years’ experience (OR = 1.8; 95% CI (1.16-2.89), and prior random dysplasia (OR = 4.2; 95% CI (1.93-9.17). Concomitant primary sclerosing cholangitis was significantly associated with random dysplasia (OR = 2.3; 95% CI, 1.02-5.07). After multivariate analysis adjusting for these variables, chromoendoscopy was no more likely to identify dysplasia than was HDWLE. Conclusions Chromoendoscopy and HDWLE had a similar diagnostic yield for dysplasia detection in patients with chronic IBD-colitis after adjusting for multiple known risk factors.

Abstract Background and Aims PH1 is a rare genetic disorder characterized by hepatic oxalate overproduction, leading to recurrent kidney stones, nephrocalcinosis, progressive kidney failure, and multiorgan damage from systemic oxalosis. There are no approved pharmacologic therapies for PH1. Lumasiran is a subcutaneously-administered investigational RNAi therapeutic that targets glycolate oxidase to reduce hepatic oxalate production. We report the first results from the six-month, double-blind period of ILLUMINATE-A, a randomized, placebo-controlled Phase 3 study to evaluate lumasiran in patients with PH1. Method Key inclusion criteria: age≥6 years, 24hr urinary oxalate (UOx)≥0.70 mmol/24hr/1.73m2, confirmed PH1 diagnosis, eGFR≥30 mL/min/1.73m2. Randomization: 2:1; lumasiran (n=26), placebo (n=13). Dosing: 3 mg/kg monthly×3, then quarterly. Primary endpoint: percent change in 24hr UOx excretion from baseline to month (M) 6. Primary comparison: least square (LS) mean treatment difference in percent change from baseline (average of M3-6). Results Lumasiran led to a statistically significant percent reduction in 24hr UOx excretion compared to placebo: the LS mean change from baseline to M6 (average of M3-6) was −65.4% with lumasiran and −11.8% with placebo (LS mean difference: −53.5%; p=1.7 × 10−14). Subgroup analyses of the primary endpoint showed a consistent effect of lumasiran across age, baseline UOx, eGFR, and concomitant pyridoxine use. Lumasiran led to statistically significant improvements in all hierarchically tested secondary endpoints, including: proportion of lumasiran-treated patients that achieved normalization or near-normalization of 24hr UOx at M6 (84% vs 0% of placebo-treated patients, p=8.3 × 10−7), and percent change in plasma oxalate from baseline to M6 (average of months 3-6) (-39.5%, p=2.9 × 10−8). There were no serious or severe adverse events. The most common adverse events related to lumasiran were mild, transient injection site reactions. Conclusion Lumasiran resulted in clinically meaningful, rapid, sustained, and statistically significant reductions in urinary and plasma oxalate levels compared to placebo during the six-month double-blind period. Lumasiran has a favorable safety profile.

The NCCN Guidelines for Cervical Cancer provide recommendations for diagnostic workup, staging, and treatment of patients with the disease. These NCCN Guidelines Insights focus on recent updates to the guidelines, including changes to first- and second-line systemic therapy recommendations for patients with recurrent or metastatic disease, and emerging evidence on a new histopathologic classification system for HPV-related endocervical adenocarcinoma.

AbstractObjectiveOrthostatic intolerance (OI) and autonomic dysfunction (AD) are common in adolescents and young adults. Patients experience multisystem symptoms including gastrointestinal (GI), postural orthostatic tachycardia syndrome (POTS), orthostatic hypotension (OH), or only symptoms of OI (SOI) without significant findings on 70‐degree head‐up tilt testing (HUT). We hypothesize that patients with POTS, OH, and SOI show differences in GI symptoms and motility test and that heart rate (HR) changes on HUT predict severity of GI dysmotility.Study designFrom medical records of patients (<18 years) with OI, we collected demographics, presenting symptoms, GI manifestations, and GI motility testing. Data were compared between the 3 groups (POTS, OH, and SOI). We assessed changes in HR on HUT with changes on GI motility evaluation.ResultsTwo hundred twenty‐nine patients were included (73% females). Abdominal pain (65%), nausea (49%), vomiting (18%), and constipation (24%) were the most common GI symptoms. In patients who had motility evaluation, there were 27% (53/193) with delayed gastric emptying (GE) at 4 hours, 35% (32/92) with delayed colonic transit (CT), 55% (17/31) with reduced gastric accommodation (GA), and 75% (21/28) with dyssynergic defecation (DD). Among 100 POTS, 34 OH, and 95 SOI patients, no significant differences in GI symptoms or motility tests were identified and HR changes on HUT were not associated with changes on motility tests.ConclusionGI symptoms are frequent in adolescents with OI and are associated with delayed GE, reduced GA, delayed CT, and presence of DD.
