Goltz Syndrome With Large Esophageal Squamous Papillomas—A Unique Cause of Dysphagia Amenable to Endoscopic Treatment
Focal dermal hypoplasia, also referred to as Goltz syndrome, is a rare X-linked dominant multisystem disorder primarily affecting women, with an estimated prevalence of roughly 1 per 1 million individuals. The condition arises from pathogenic variants in the PORCN gene, resulting in disrupted Wnt signaling and subsequent developmental abnormalities involving the skin, skeletal system, and various other tissues. While mucocutaneous papillomas commonly affect the oral cavity and pharynx, distal gastrointestinal manifestations are infrequent. This report describes an exceptionally unusual case of focal dermal hypoplasia with multiple esophageal squamous papillomas causing symptomatic obstruction, which was effectively managed by endoscopic mucosal resection.

Impact of Prior Bariatric Surgery on Labor and Delivery-Related Outcomes: A Nationwide Study
Background Limited literature exists on labor and delivery outcomes after bariatric surgery. This study assesses the impact of prior bariatric surgery on peripartum outcomes. Methods We queried the National Inpatient Sample (2016–2020) for labor and delivery admissions, categorizing them into three cohorts: prior bariatric surgery (BaS), obesity without prior bariatric surgery, and controls without obesity. We used a multivariate regression model, adjusting for confounders, to compare peripartum outcomes. Results We identified 22,685 BaS cases, 2.1 million pregnant controls with obesity, and 16.37 million pregnant controls without obesity. Compared to controls with obesity, the BaS cohort had lower rates of cesarean delivery [43% vs 46.8%, adjusted odds ratio (aOR) 0.72, p < 0.001], fetal distress [aOR 0.79, p < 0.001), post-partum hemorrhage (aOR 0.67, p < 0.001), fetal disproportion (aOR 0.36, p < 0.001), and premature rupture of membranes (aOR 0.88, p = 0.04). Compared to controls without obesity, the BaS group had higher rates of cesarean delivery (43% vs 29.57%, aOR 1.43, p < 0.001), breech presentation (aOR 1.4, p < 0.001), thromboembolic events (aOR 2.47, p = 0.01), and pregnancy termination (aOR 1.59, p = 0.048), but lower rates of assisted delivery (aOR 0.54, p < 0.001), fetal disproportion (aOR 0.56, p = 0.025), PROM (aOR 0.87, p = 0.024), and placenta previa (aOR 0.63, p = 0.019). The BaS group had longer hospitalizations (3.11 vs 2.56 days, p < 0.001) and higher hospitalization charges ($25,941 vs $20,760, p < 0.001) compared to controls without obesity. Conclusion Pregnancy after bariatric surgery is associated with lower odds of cesarean delivery and postpartum complications, relative to the general population with obesity. This underscores the positive impact of bariatric surgery on peripartum outcomes.

Trends and Disparities in Colonic Diverticular Disease Hospitalizations in Patients With Morbid Obesity: A Decade-Long Joinpoint Analysis
Objective We aimed to describe epidemiologic trends in outcomes of colonic diverticular disease (CDD) hospitalizations in morbidly obese patients. Methods We searched the United States National Inpatient Sample databases from 2010 through 2019, obtained the incidence rate of morbid obesity (MO) among CDD hospitalizations, and used Joinpoint analysis to obtain trends in these rates adjusted for age and sex. Hospitalizations involving patients less than 18 years of age were excluded. Trends in mortality rate, mean length of hospital stay (LOS), and mean total hospital charge were analyzed. Multivariate regression analysis was used to obtain trends in adjusted mortality, mean LOS, and mean total hospital charge. Results We found an average annual percent change of 7.5% (CI = 5.5-9.4%, p < 0.01) in the adjusted incidence of MO among hospitalizations for CDD over the study period. We noted a 7.2% decline in mortality (p = 0.011) and a 0.1 days reduction in adjusted LOS (p < 0.001) over the study period. Hospitalizations among the middle-aged and elderly had adjusted odds ratios of 7.18 (95% CI = 2.2-23.3, p = 0.001) and 24.8 (95% CI = 7.9-77.9, p < 0.001), respectively, for mortality compared to those in young adults. The mean LOS was 0.29 days higher in females compared to males (p < 0.001). Conclusion The incidence of MO increased among CDD hospitalizations while mortality and mean LOS reduced over the study period. Outcomes were worse in older patients, with an increased mean LOS in females compared to males.

Different Approaches to the Management of Cholecystoenteric Fistula
A cholecystoenteric fistula is an anomalous communicating tract between the gallbladder and any segment of the gastrointestinal tract. It is a rare complication of gallstone disease and typically affects elderly patients with multiple medical comorbidities. These fistulae can present in a variety of ways, and the diagnosis is often made only after extensive workup. Despite notable advances in imaging techniques in the last half-century, a considerable number of cases are still discovered incidentally during open or laparoscopic surgery. We present a series of 3 cases, each with different etiologies and presentations, but all of whom were found to have a cholecystoenteric fistula. Each case was managed differently, highlighting the diversity of this intriguing condition.

Diurnal Fasting During Ramadan Leading to Superior Mesenteric Artery Syndrome
Superior mesenteric artery (SMA) syndrome is a favorite of anatomists and clinicians because it results from extrinsic compression of the duodenum by the 2 vascular structures forming the aortomesenteric angle (the descending abdominal aorta and the SMA). Although it is an uncommon cause of upper gastrointestinal obstruction, SMA syndrome can cause significant morbidity. It is more common in younger people. Historically, it has been associated with weight loss and eating disorders, but there are several other risk factors that should be considered in the workup. Cases of SMA syndrome are typically managed conservatively, but surgical referral and intervention may be considered in situations that fail conservative management. We present a case of this rare syndrome in a young man with no medical or psychiatric history during diurnal voluntary fasting in the month of Ramadan.

More Than Meets the Eye: Isolated Bilateral Abducens Nerve Palsy as the Initial Presentation of Multiple Sclerosis
Multiple sclerosis (MA) is a chronic demyelinating disease of the central nervous system. Although the initial presentation of MS is widely variable, only rarely does it present with isolated bilateral cranial nerve involvement. With this article, we report a case of MS initially presenting as a clinically isolated syndrome of bilateral abducens nerve palsy.

Cytokine Release Syndrome Following Blinatumomab Therapy
New therapeutic solutions have emerged in the last few decades with the growth and expansion of the field of cancer research. Amongst these new agents, immunotherapy has been prominent, particularly regarding the treatment of hematologic malignancies. One of the most worrisome complications of immunotherapy is cytokine release syndrome (CRS), which represents a supraphysiologic response resulting in excessive release of cytokines and a wide range of systemic manifestations. In this case report, we present a case of cytokine release syndrome following blinatumomab therapy despite premedication with dexamethasone.
