The Burden of Cost in Inflammatory Bowel Disease: A Medical Economic Perspective and the Future of Value-Based Care.

PURPOSE OF REVIEW: To examine the quantifiable economic impact of inflammatory bowel disease (IBD), key cost drivers and determinants, and the impact of value-based care in IBD. Finally, we prognosticate on future directions and opportunities on healthcare economics in IBD. RECENT FINDINGS: New value-based initiatives, technologically driven interventions, and quality improvement programs have demonstrated reductions in healthcare utilization and enhanced patient outcomes, and several have realized cost of care reductions. IBD is a costly, chronic illness with unbalanced spending by a small proportion of individuals. Pharmaceutical costs are overtaking inpatient expenses as the primary cost driver. Value-based care initiatives including the IBD medical home, remote monitoring platforms such as myIBDcoach and Project Sonar, and learning healthcare networks exemplified by ImproveCareNow have all demonstrated successes in improving care quality, patient outcomes, and reduced healthcare spending in some populations. The future of value-based care in IBD is bright, with ample opportunities for model refinement, collaboration, and growth.

An update on cancer risk and surveillance in primary sclerosing cholangitis.

Malignancy represents substantial morbidity and mortality in patients with primary sclerosing cholangitis (PSC). This subset of patients has been proven to be at increased risk for developing cholangiocarcinoma, gallbladder carcinoma and colorectal cancer in those with overlapping inflammatory bowel disease. Herein, we review the prevalence of these malignancies and recommend screening tools and current knowledge to reduce the disease burden in this population. Cholangiocarcinoma is the most dominant malignancy affecting PSC patients, with a lifetime risk ranging from 5% to 20%. We advocate for serial US or MRI/MRCP and CA 19-9 to screen for cholangiocarcinoma. Gallbladder cancer has a lifetime risk around 2% in this population and we agree with annual imaging for lesions as recommended by national guidelines. Patients with PSC and concomitant IBD are at increased risk of colorectal carcinoma from time of diagnosis and therefore should likely undergo annual surveillance. The low rates of hepatocellular cancer and pancreatic cancer indicate surveillance for these malignancies is less advantageous.

[Small cell lung cancer associated with multiple paraneoplastic syndromes].

We report the case of a patient presenting with multiple severe electrolyte disturbances who was subsequently found to have small cell lung cancer. Upon further evaluation, she demonstrated three distinct paraneoplastic processes, including the syndrome of inappropriate antidiuretic hormone, Fanconi syndrome, and an inappropriate elevation in fibroblast growth factor-23 (FGF23). The patient underwent one round of chemotherapy, but she was found to have progressive disease. After 36 days of hospitalization, the patient made the decision to enter hospice care and later she expired.

Approach to Incomplete Colonoscopy: New Techniques and Technologies.

Colonoscopy is the most widely used screening modality for the detection and removal of colon polyps and for the prevention of colorectal cancer. To identify all colon lesions and reduce the risk of colorectal cancer, it is important to perform a complete colonoscopy. The success of screening colonoscopy depends upon several parameters, including bowel preparation and adenoma detection rate. Incomplete colonoscopy rates vary from 4% to 25% and are associated with higher rates of interval proximal colon cancer. This article reviews the potential causes of and preventive measures for incomplete colonoscopy, as well as techniques and technologies that may improve the rate of complete colonoscopy.

Black Cohosh Hepatotoxicity with Autoimmune Hepatitis Presentation.

Herbal medicines have been used for the treatment of various ailments since time immemorial. Black cohosh (BC) is well known for the treatment of postmenopausal symptoms, with conflicting evidence supporting its safety and benefits. We present a rare case of BC-induced autoimmune hepatitis (AIH) with hepatotoxicity in a 69-year-old female. To our knowledge, this represents the third case of BC-induced AIH.

Spontaneous circadian rhythms in a cold-adapted natural isolate of Aureobasidium pullulans.

Circadian systems enable organisms to synchronize their physiology to daily and seasonal environmental changes relying on endogenous pacemakers that oscillate with a period close to 24 h even in the absence of external timing cues. The oscillations are achieved by intracellular transcriptional/translational feedback loops thoroughly characterized for many organisms, but still little is known about the presence and characteristics of circadian clocks in fungi other than Neurospora crassa. We sought to characterize the circadian system of a natural isolate of Aureobasidium pullulans, a cold-adapted yeast bearing great biotechnological potential. A. pullulans formed daily concentric rings that were synchronized by light/dark cycles and were also formed in constant darkness with a period of 24.5 h. Moreover, these rhythms were temperature compensated, as evidenced by experiments conducted at temperatures as low as 10 °C. Finally, the expression of clock-essential genes, frequency, white collar-1, white collar-2 and vivid was confirmed. In summary, our results indicate the existence of a functional circadian clock in A. pullulans, capable of sustaining rhythms at very low temperatures and, based on the presence of conserved clock-gene homologues, suggest a molecular and functional relationship to well-described circadian systems.

Endoscopic findings of primary follicular lymphoma.

A 79-year-old female with benign past medical history presented to the gastroenterology clinic complaining of long-standing symptoms of dyspepsia. Esophagogastroduodenoscopy showed nodular smooth mucosa in the second part of the duodenum. The morphologic and immunophenotypic findings were consistent with low-grade follicular lymphoma. The purpose of this manuscript is to educate the reader on this unusual finding that is pathognomonic for gastrointestinal lymphoma.

Presentation, Diagnosis, and Management of Esophageal Lichen Planus: A Series of Six Cases.

Lichen planus (LP) is an idiopathic disorder that presents with cutaneous and genital manifestations. Esophageal LP (ELP) was first described by Al-Shihabi and Jackson [J Laryngol Otol 1982;96:567-571] in 1982. Only approximately 80 cases have been documented in the literature since. It is a rare and underrecognized disorder, leading to a delay in diagnosis and a lack of standardized management. We describe the presentation, diagnosis, and management of 6 cases of ELP, at a tertiary institution, because we believe that an increasing awareness of this condition can help identify more cases and increase our understanding of this interesting condition.

Duodenal Aspirates for Small Intestine Bacterial Overgrowth: Yield, PPIs, and Outcomes after Treatment at a Tertiary Academic Medical Center.

Duodenal aspirates are not commonly collected, but they can be easily used in detection of small intestinal bacterial overgrowth (SIBO). Proton pump inhibitor (PPI) use has been proposed to contribute to the development of SIBO. We aimed to determine the yield of SIBO-positive cultures detected in duodenal aspirates, the relationship between SIBO and PPI use, and the clinical outcomes of patients identified by this method. In a retrospective study, we analyzed electronic medical records from 1263 consecutive patients undergoing upper endoscopy at a tertiary medical center. Aspirates were collected thought out the third and fourth portions of the duodenum, and cultures were considered to be positive for SIBO if they produced more than 100,000 cfu/mL. Culture analysis of duodenal aspirates identified SIBO in one-third of patients. A significantly higher percentage of patients with SIBO use PPIs than patients without SIBO, indicating a possible association. Similar proportions of patients with SIBO improved whether or not they received antibiotic treatment, calling into question the use of this expensive therapy for this disorder.

Eosinophilic granulomatosis with polyangiitis and diffuse gastrointestinal involvement.

Eosinophilic granulomatosis with polyangiitis (EGPA), formerly named Churg-Strauss syndrome, is a rare systemic small- and medium-sized-vessel vasculitis, characterized by the presence of severe asthma as well as blood and tissue eosinophilia. Gastrointestinal (GI) symptoms, like diarrhea and abdominal pain, are common; however, there are few reports of histologic evidence of GI involvement. We report the case of a patient on treatment for EGPA who presented with recurrent small bowel obstruction and choledocholithiasis. Biopsies of the esophagus, small bowel and common bile duct showed diffuse eosinophilia, with clear EGPA in the GI tract. Improved awareness of GI EGPA may allow for timely management of this disorder.

[Wernicke´s encephalopathy and polyneuropathy associated with vitamin B complex deficiency after a bariatric surgery]. / Encefalopatía de Wernicke y polineuropatía asociada a déficit de complejo B después de una cirugía bariátrica.

Bariatric surgery is a treatment that guarantees a substantial and lasting weight loss in addition to the tangible benefits relating to obesity-associated medical conditions. The increasing number of bariatric surgeries has revealed an increasing number of complications related to this procedure, including Wernicke´s encephalopathy and vitamin B deficiency polyneuropathies. Herein, a 7-week post-surgery case of Wernicke´s encephalopathy is presented that emphasizes the importance of an early recognition of these symptoms so as to initiate intervention during the reversible phase of these potentially lethal pathologies.
