RESUMEN
BACKGROUND AND STUDY AIM: The incidence of cholangiocarcinoma (CCA) in primary sclerosing cholangitis (PSC) ranges between 7 and 14 %. Despite using multiple tissue sampling modalities, detection of CCA remains a challenge. Probe-based confocal laser endomicroscopy (pCLE) has been utilized to visualize subepithelial biliary mucosa in patients with indeterminate strictures. We assessed the technical feasibility and operating characteristics of pCLE in a cohort of PSC patients with dominant biliary strictures (DS). PATIENTS AND METHODS: This was a chart review of a prospectively maintained database at a single tertiary referral center of 15 PSC patients with 21 dominant stenoses undergoing pCLE. A data collection sheet included demographics, ERCP, cholangioscopy, pCLE (Miami criteria), tissue sampling results, and follow-up to 12 months or liver transplantation. Operating characteristics for pCLE and ERCP tissue sampling were calculated. RESULTS: Sufficient visualization of DS by pCLE was achieved in 20/21 (95 %). pCLE sensitivity, specificity, PPV, and NPV were 100 % (95 % CI 19.3-100 %), 61.1 % (95 % CI 35.8-82.6 %), 22.2 % (95 % CI 3.5-59.9 %), and 100 % (95 % CI 71.3-100 %), respectively, in detecting neoplasia. In comparison, concomitant tissue sampling yielded sensitivity, specificity, PPV, and NPV of 0 % (95 % CI 0-80.7 %), 94.4 % (95 % CI 72.6-99.1 %), 0 % (95 % CI 0-83.5 %), and 89.5 % (95 % CI 66.8-98.4 %), respectively. CONCLUSIONS: pCLE achieves a high technical success rate in patients with PSC and DS. This single center, small series, suggests that pCLE may have a high sensitivity and negative predictive value to exclude neoplasia. If verified in larger prospective studies, the technology may be utilized to risk stratify dominant strictures in patients with PSC.

OBJECTIVES: To determine the relationships between physical function, systemic inflammation, and nutrient intake in elderly adults who are deconditioned or recovering from medical illness. DESIGN: Prospective observational study. SETTING: Recuperative care and rehabilitation setting of a Veterans Affairs hospital. PARTICIPANTS: Older adults assessed to be in need of and likely to benefit from specialized inpatient care (N = 336, aged 78.9 ± 7.5, median length of stay 24 days). MEASUREMENTS: Functional assessments and plasma analyses for albumins and inflammatory markers were performed at admission and discharge. Complete nutrient intake assessments were performed daily. Katz (independence in activities of daily living) and walking endurance (distance capability and summation of need for assistive device and human help) scores were based on direct observation and provider query. Data were analyzed using least-squares and logistic regression analyses. RESULTS: Changes in physical function between admission and discharge were positively correlated with change in nutrient intake and inversely correlated with inflammation at admission and its change. Participants in the upper quartile of change for nutrient intake (particularly improved protein intake) were two to three times as likely to experience a clinically significant change in functional status during the hospitalization. Similarly, the odds of experiencing an improvement in physical function were two to four times as great for participants whose C-reactive protein levels declined as for those whose levels increased. These relationships remained significant after controlling for age, length of stay, and other baseline indicators of health status. CONCLUSION: Protein intake and inflammation are significantly correlated with functional recovery for aging individuals undergoing recuperative care and rehabilitation. Future studies should investigate whether combined interventions that target these factors improve recovery during hospitalization for this population.

CONTEXT: We submit a case of intrapancreatic accessory spleen. CASE REPORT: A 33-year-old patient with history of dyspepsia underwent imaging studies suggestive of a neuroendocrine tumor. After referral to our institute, endoscopic ultrasound guided fine needle aspiration (EUS-FNA) confirmed diagnosis as intrapancreatic accessory spleen. DISCUSSION: An accessory spleen may develop from estranged mesenchymal cells due to fusion failure of the splenic anlage. The prevalence of an accessory spleen is 10-30% with 80% of them present at the splenic hilum and 17% in the pancreatic tail. Intrapancreatic accessory spleen is commonly misdiagnosed as a pancreatic tumor. Since, the differential diagnosis includes pancreatic neuroendocrine tumors, additional investigation with EUS-FNA should be considered when radiological diagnosis is not definitive. CONCLUSION: For diagnosis of intrapancreatic accessory spleen, radiographic imaging is useful, but lacks specificity without tissue diagnosis. Diagnosis can be safely and reliably established with EUS-FNA, leading to a benign prognosis and avoidance of unnecessary surgical intervention.

Strongyloides stercoralis affects 30 to 100 million people worldwide and is a common cause of abdominal pain and diarrhea. Strongyloidiasis is a chronic and limited disease; however, in immunocompromised patients, hyperinfection syndrome can occur. Diagnosing strongyloidiasis early is important, as almost all deaths due to helminths in the United States are due to S stercoralis hyperinfection. Patients infected with human immunodeficiency virus (HIV) do not appear to be at an increased risk for S stercoralis hyperinfection. We report a case of an HIV-infected Hispanic woman presenting with dyspepsia, emesis, abdominal pain, and diarrhea diagnosed with S stercoralis on an esophagogastroduodenoscopy biopsy of the duodenum. The diagnostic workup had been inconclusive and deciding to biopsy the small bowel based on the nonerythematous boggy appearance of the duodenal folds was the key step in making the correct diagnosis. Early diagnosis and treatment thwarted the developing hyperinfection syndrome and likely prevented further morbidity and probably saved her life.

Wound botulism is exceedingly rare and occurs almost exclusively among injection drug users. In 2008 there was a case of wound botulism in a noninjecting drug user reported to the Centers for Disease Control and Prevention (CDC). We report a case of a Caucasian male developing dysphagia due to wound botulism after having a motorcycle accident that left him with open fractures. The CDC was contacted and the patient was transferred to medical intensive care unit to be emergently started on hepatavalent Clostridium botulinum antitoxin. Early suspicion of wound botulism is essential for effective therapy with antitoxin in this life-threatening disease. If not suspected, this patient would likely have died. Nevertheless, the delay in diagnosis and treatment resulted in the patient's suffering dysphagia and neurological deficits. The patient required a percutaneous endoscopic gastrostomy tube and months of dysphagia therapy, supportive care, and rehabilitation. Our aim is to increase the awareness for wound botulism when a patient presents with dysphagia and diplopia after suffering open wounds. If suspected early, the morbidity and mortality from this disease can be prevented.

OBJECTIVES: To determine the relationship between prealbumin, nutrient intake, and indicators of inflammation for recuperative and rehabilitative care patients. DESIGN: Prospective cohort. SETTING: Recuperative Care Unit within a Veterans Administration Nursing Home Care Unit. PARTICIPANTS: One hundred eleven men (100 white; mean age 80, range 64-93). MEASUREMENTS: Prealbumin and seven markers of inflammation (C-reactive protein (CRP), tumor necrosis factor, and interleukin-6 (IL-6) and their soluble receptors) were measured at admission and discharge (median length of stay 23 days, interquartile range 15-40 days). Detailed calorie counts were performed daily, and intake was expressed as a percentage of estimated requirements for protein (1.5 g/kg body weight per day) and energy (Harris-Benedict equation). The study objective was examined using least-squares regression analysis. RESULTS: Discharge prealbumin and the change in prealbumin were positively correlated with protein and energy intake and inversely correlated with markers of inflammation, particularly CRP and IL-6. When all covariates were included in a multivariable regression analysis, the markers of inflammation predominantly accounted for the variance in prealbumin change (56%), whereas discharge protein intake accounted for 6%. CONCLUSION: For older recuperative care patients, prealbumin and its change during hospitalization are positively associated with protein intake, but inflammation or changes in inflammation appear to exert a much more-powerful influence on prealbumin concentration. Given the potential confounding effects of inflammation, monitoring the change in prealbumin is not an adequate substitute for a more-detailed nutritional assessment in this population.
