Purpose of Review: Gastroesophageal reflux disease (GERD) is a commonly recognized cause of dysphagia. Conversely, eosinophilic esophagitis (EoE) and celiac disease are rarer and often overlooked as dysphagia culprits. Overlap between these conditions complicates diagnosis and delays appropriate treatment. This review aims to clarify the distinctive dysphagia characteristics in each condition, explore potential overlaps, and offer guidance on differentiation., Recent Findings: Recent studies have advanced our understanding of dysphagia mechanisms in GERD, EoE, and celiac disease, particularly in characterizing disordered motility and dysphagia's natural history. While upper endoscopy, biopsies, and manometry remain crucial in dysphagia assessment, novel diagnostic tools are emerging. New insights highlight the significance of cytokine-induced mucosal injury in all three conditions, revealing potential connections where mucosal damage in one disorder may contribute to the development of others., Summary: GERD, EoE, and celiac disease can coexist and present with similar symptoms. Distinguishing between them often entails upper endoscopy, esophageal biopsies, pH testing, and celiac serologies. EoE should be considered when GERD patients fail proton pump inhibitor therapy or when celiac patients have persistent esophageal symptoms despite a gluten-free diet. Consider celiac disease if dysphagia accompanies iron deficiency anemia, malabsorptive diarrhea, or osteoporosis. Recognizing the potential overlap between these conditions is crucial for guiding clinical evaluation and therapy., (Copyright © 2024 Wolters Kluwer Health, Inc. All rights reserved.)

Purpose of Review: Optimal pain control in living liver donors undergoing hepatectomy is strongly recommended considering their unique status as healthy individuals willingly undergoing surgery for the benefit of the recipient. This review aims to examine and evaluate different strategies aimed at ensuring effective postoperative pain management in living liver donors., Recent Findings: Enhanced recovery after surgery (ERAS) protocols have proven effective in optimizing patient outcomes, including in living liver donor hepatectomy. By implementing these protocols, healthcare professionals can enhance postoperative pain control and accelerate recovery. Multimodal analgesia, which combines different techniques and agents, is crucial in pain management for living liver donors. Regional analgesia techniques, such as spinal anesthesia and various peripheral nerve blocks, have shown efficacy in reducing pain and facilitating early recovery. Systemic nonopioid analgesics, including acetaminophen, nonsteroidal anti-inflammatory drugs, ketamine, lidocaine, and dexmedetomidine act synergistically to alleviate pain and reduce inflammation. Minimizing the use of opioids is important to avoid adverse effects, and they should be reserved for rescue medication or breakthrough pain., Summary: Applying the principles of ERAS and multimodal analgesia to living liver donors can effectively control pain while promoting early recovery., (Copyright © 2023 Wolters Kluwer Health, Inc.

Objective: We sought to evaluate the impact of liver transplantation (LT) programs on the prognosis of hepatocellular carcinoma (HCC) patients who underwent liver resection (LR) and noncurative intent treatment., Background: LT programs have an array of resources and services that would positively affect the prognosis of patients with HCC., Methods: Patients who underwent LT, LR, radiotherapy (RT), or chemotherapy (CTx) for HCC between 2004 and 2018 were included in the National Cancer Database. Institutions with LT programs were defined as those that performed 1 or more LT for at least 5 years. Centers were stratified by hospital volume. The impact of LT programs was assessed after propensity score matching to achieve covariate balance., Results: A total of 71,735 patients were identified, of which 7997 received LT (11.1%), 12,683 LR (17.7%), 15,675 RT (21.9%), and 35,380 CTx (49.3%). Among a total of 1267 distinct institutions, 94 (7.4%) were categorized as LT programs. Designation as an LT program was also associated with a high volume of LR and noncurative intent treatment (both P <0.001). After propensity score matching, LT programs were associated with better survival among LR and noncurative intent treatment patients. Although hospital volume was also associated with improved prognosis, LT programs were associated with additional survival benefits in noncurative intent treatment. On the other hand, no such benefit was noted in patients who underwent LR., Conclusions: The presence of an LT program was associated with a higher volume of LR and noncurative intent treatment. Furthermore, designation as an LT program had a "halo effect" on the prognosis of patients undergoing RT/CTx that went beyond the procedure-volume effect., Competing Interests: The authors report no conflicts of interest., (Copyright © 2023 Wolters Kluwer Health, Inc.

This article provides a narrative review of the state of the science for both cyclic vomiting syndrome and cannabis hyperemesis syndrome along with a discussion of the relationship between these 2 conditions. The scope of this review includes the historical context of these conditions as well as the prevalence, diagnostic criteria, pathogenesis, and treatment strategies for both conditions. A synopsis of the endocannabinoid system provides a basis for the hypothesis that a lack of cannabidiol in modern high-potency Δ 9 -tetrahydrocannabinol cannabis may be contributory to cannabis hyperemesis syndrome and possibly other cannabis use disorders. In concluding assessment, though the publications addressing both adult cyclic vomiting syndrome and cannabis hyperemesis syndrome are steadily increasing overall, the state of the science supporting the treatments, prognosis, etiology, and confounding factors (including cannabis use) is of moderate quality. Much of the literature portrays these conditions separately and as such sometimes fails to account for the confounding of adult cyclic vomiting syndrome with cannabis hyperemesis syndrome. The diagnostic and therapeutic approaches are, at present, based generally on case series publications and expert opinion, with a very limited number of randomized controlled trials and a complete absence of Level 1 evidence within the cyclic vomiting literature overall as well as for cannabis hyperemesis syndrome specifically., (Copyright © 2023 Society of Gastroenterology Nurses and Associates.)

Breakthrough cancer pain (BTcP) is an episode of severe pain that "breaks through" a period of persistent pain at least partly controlled by a stable opioid regimen. Although mentioned in the literature decades ago, it has been only 25 years since the first effort to define and measure it. Controversy about the definition of BTcP continues despite an international effort to achieve consensus. Nevertheless, common approaches to measurement of BTcP have led to a robust literature, including many surveys that have described prevalence, characteristics, and association with adverse outcomes. Measurement also has been important for clinical trials of new drug formulations specifically designed for BTcP. Several approaches have been reported in the literature, although most of them have never been substantiated with appropriate studies. Administration of an opioid as needed is the most common treatment. Twenty-five years of research has produced a more refined understanding of the safety and efficacy of oral opioids in this context, and provided the clinical trials data necessary to attain regulatory approval of multiple new formulations specifically developed for BTcP. Transmucosal formulations of fentanyl may provide meaningful analgesia within 5 to 15 minutes. Given the difference in cost, transmucosal formulations should be considered in a subset of patients with BTcP, including those with pain that are not adequately controlled with an oral drug and those with distress associated with the rapid pain onset. The long-term use of opioids for BTcP remains to be clarified. Future studies should assess the potential of personalized treatment of BTcP.

Pain originating from the female reproductive organs is a substantial clinical problem to treat. Experimental models may be a tool for the study of visceral pain mechanisms and hence provide information to aid in formulating new treatment strategies. The aim was to develop and evaluate the performance and safety of a model for nociceptive stimulation of the uterine cervix by balloon dilatation using impedance planimetry. Three consecutive (repeated) dilatations at 1 ml/min, an isovolumetric and a fast dilatation at 2 ml/min were performed. Pilot studies were conducted in vitro on hysterectomy specimens, followed by application of the model in 14 healthy females. Subjects indicated the quality of perception and pain during dilatations by verbal reports and the McGill Pain Questionnaire (MPQ), and the intensity by a continuous electronic visual analog scale. The pain location was marked on an anatomical map. The balloon cross-sectional area (CSA) was measured simultaneously. The experimental procedure was atraumatic. Pain was evoked in all subjects, with referral to the hypogastric and low back regions. The word descriptors on the MPQ and the areas of referred sensations were similar to that seen clinically in abortion, labor and menstrual pain. The pain intensity correlated with balloon CSA (r=0.9, P<0.001). No significant differences were found for the balloon volumes (4.2, 3.8 and 3.9 ml) or CSA (163, 122 and 123 mm(2)) to pain threshold (PT) for repeated dilatations, suggesting the reliability of the model. There was significant correlation between the balloon volume and CSA to reach the PT for single and repeated cervical dilatations. During isovolumetric distension, greater overall pain intensity was demonstrated for the prolonged as compared to the shorter duration cervical stimulation. In conclusion, this is the first human experimental pain model for dilatation of the uterine cervix, providing a safe, controlled, quantifiable stimulus that evoked reliable pain scores. The model thus provides a new possibility to study gynecological pain and may lead to better characterization and treatment of female visceral pain syndromes.
