Management of Opioid-induced Constipation in Older Adults.

Opioid-induced constipation (OIC) is a common condition in older adults who may not be responsive to traditional laxative therapy. OIC is defined as new or worsening constipation symptoms that occur with initiation of or altering the dose of opioid analgesia. For adult patients with OIC and noncancer pain, we recommend considering nonpharmacologic interventions (eg, dietary measures, increased physical activity, and biofeedback training) and over-the-counter laxatives, followed by prescription opioid receptor antagonists (methylnaltrexone, naloxegol, and naldemedine) if traditional over-the-counter laxatives fail. Other options may include lubiprostone, linaclotide, plecanatide, and prucalopride; however, these are not indicated for OIC specifically or studied in older adults. Because of the complex nature of absorption, distribution, metabolism, and excretion in the aging population, all agents used to treat OIC must be evaluated individually and reevaluated as patients continue to age. This review will serve as a guide to managing OIC in older adults.

Learning Curve for Endoscopic Submucosal Dissection With an Untutored, Prevalence-Based Approach in the United States.

BACKGROUND & AIMS: Endoscopic submucosal dissection (ESD) is widely used in Asia to resect early-stage gastrointestinal neoplasms, but use of ESD in Western countries is limited. We collected data on the learning curve for ESD at a high-volume referral center in the United States to guide development of training programs in the Americas and Europe. METHODS: We performed a retrospective analysis of consecutive ESDs performed by a single operator at a high-volume referral center in the United States from 2009 through 2017. ESD was performed in 540 lesions: 449 mucosal (10% esophageal, 13% gastric, 5% duodenal, 62% colonic, and 10% rectal) and 91 submucosal. We estimated case volumes required to achieve accepted proficiency benchmarks (>90% for en bloc resection and >80% for histologic margin-negative (R0) resection) and resection speeds >9cm2/hr. RESULTS: Pathology analysis of mucosal lesions identified 95 carcinomas, 346 premalignant lesions, and 8 others; the rate of en bloc resection increased from 76% in block 1 (50 cases) to a plateau of 98% after block 5 (250 cases). The rate of R0 resection improved from 45% in block 1 to >80% after block 5 (250 cases) and ∼95% after block 8 (400 cases). Based on cumulative sum analysis, approximately 170, 150, and 280 ESDs are required to consistently achieve a resection speed >9cm2/hr in esophagus, stomach, and colon, respectively. CONCLUSIONS: In an analysis of ESDs performed at a large referral center in the United States, we found that an untutored, prevalence-based approach allowed operators to achieve all proficiency benchmarks after ∼250 cases. Compared with Asia, ESD requires more time to learn in the West, where the untutored, prevalence-based approach requires resection of challenging lesions, such as colon lesions and previously manipulated lesions, in early stages of training.

Esophageal Button Battery Retrieval: Time-In May Not Be Everything.

The management of ingested foreign bodies is a challenging task because each case is unique with multiple varying factors including a patient's age, anatomical considerations, clinical presentation, and the type and location of the foreign body ingested. Additionally, concern over complications associated with button battery ingestion typically drives management decisions. The common practice is the urgent retrieval of the foreign body within two to six hours of presentation. An unusual case is presented here that demonstrated significantly delayed endoscopic removal of an ingested button battery without complication, avoiding the many risks associated with any emergent endoscopic procedure. However, this practice is a case-by-case decision because there is a lack of literature to guide the current management.

Seronegative Autoimmune Hepatitis.

Autoimmune hepatitis (AIH) is a relatively rare liver disease with varying worldwide incidence of from 0.7 to 2 per 100,000 people. It is characterized by the presence of auto-antibodies. However, an average of 10% of AIH cases have AIH symptoms and pathology but lack autoimmune serology. For such seronegative AIH (snAIH) cases, there is currently no established diagnostic algorithm for diagnosis. and improper or delayed diagnosis of snAIH can lead to no or inappropriate treatment that results in progression to fulminant hepatitis or cirrhosis. This review aims to review the current literature and to present an update of seronegative autoimmune hepatitis, including its pathophysiology, clinical presentation, methods of diagnosis, and treatment in order to increase awareness and emphasize the necessity for timely management.

Rehumanizing Clinical Language Through Classical Indian Dance.

Members of communities of color have long experienced structural marginalization and biases that have measurable health consequences. When a group of medical students choreograph and perform Kuchipudi and Bharatanatyam forms of Indian classical dance, they illuminate a collaborative, narrative approach to interrogating ethnic and racial biases in clinical jargon. In these video recordings of "Bagalamukhi's Words," performers interpret a patient's embodied, visceral responses to language-induced dehumanization during a clinical encounter. The accompanying commentary helps viewers consider how traditional dance, such as classical Indian dance, is useful as a narrative approach to ethics in health care documentation and communication practices.
