Case Report: Kryptonite-A Rare Case of Left-Sided Bilothorax in a Sickle Cell Patient.

Bilothorax is a rare cause of an exudative pleural effusion. The diagnosis is confirmed by a pleural fluid to serum bilirubin ratio of greater than 1. Typically, bilothorax presents as a right-sided effusion due to its proximity to the liver and biliary system. Herein, we present a case of isolated left-sided bilothorax in a 43-year-old female admitted with sickle cell crisis. Only one other case of isolated spontaneous left-sided bilothorax has been described in the literature. A thoracentesis performed on admission demonstrated greenish fluid and bilothorax was suspected, with a pleural fluid to serum bilirubin ratio greater than 1 confirming the diagnosis. A magnetic resonance cholangiopancreatography (MRCP) showed an abnormal 90-degree acute angulation in the mid-to-distal common bile duct with proximal common bile duct and intrahepatic bile ducts dilation. This was further confirmed with an endoscopic retrograde cholangiopancreatography (ERCP), which did not reveal any extravasation of contrast into the left pleural space. Ultimately, despite the use of various modalities, no definitive cause of bilothorax was identified. Postthoracentesis imaging revealed evidence of fibrothorax, a direct and permanent complication of bilothorax. The presence of an isolated left-sided bilothorax, along with the lack of a confirmed etiology, makes this case unique.

Multiple gastrointestinal complications of crack cocaine abuse.

Cocaine and its alkaloid free base "crack-cocaine" have long since been substances of abuse. Drug abuse of cocaine via oral, inhalation, intravenous, and intranasal intake has famously been associated with a number of medical complications. Intestinal ischemia and perforation remain the most common manifestations of cocaine associated gastrointestinal disease and have historically been associated with oral intake of cocaine. Here we find a rare case of two relatively uncommon gastrointestinal complications of hemorrhage and pancreatitis presenting within a single admission in a chronic crack cocaine abuser.

Radiofrequency ablation for the treatment of radiation proctitis: a case report and review of literature.

Radiation proctitis is a frequent complication of pelvic radiation for cancer. This condition can present acutely within several weeks of radiation, or chronically many months or years after radiation, leading to rectal bleeding and transfusion-dependent anemia. Various medical and endoscopic therapies have been described to treat this condition; however, some patients fail to respond to the current standard therapies. Here we present a case of refractory radiation proctitis, with suboptimal response to other therapies, treated successfully with a novel method, radiofrequency ablation.

Pleural Empyema due to Group D Salmonella.

Non-typhi Salmonella normally presents as a bacteremia, enterocolitis, and endovascular infection but rarely manifests as pleuropulmonary disease. We present a case of a 66-year-old female with underlying pulmonary pathology, secondary to an extensive smoking history, who presented with a left-sided pleural effusion. The causative agent was identified as being group D Salmonella. Decortication of the lung was performed and the patient was discharged on antibiotics with resolution of her symptoms. This case helps to support the inclusion of Salmonella group D as a possible etiological agent of infection in the differential causes of exudative pleural effusions.

Replacement gastrostomy tube causing acute pancreatitis: case series with review of literature.

CONTEXT: Percutaneous endoscopic gastrostomy (PEG) feedings are generally considered safe with few serious complications. Acute pancreatitis is a rare complication associated with replacement percutaneous endoscopic gastrostomy tubes. CASE REPORT: We report two cases of acute pancreatitis induced by migrated replacement percutaneous endoscopic gastrostomy tubes. CONCLUSIONS: Migration of a balloon into the duodenum can result in external manipulation of the ampulla of Vater thereby disturbing the flow of pancreatic secretions leading to acute pancreatitis. Recognition of this complication is important and should be included as potential etiology of acute pancreatitis in patients receiving percutaneous endoscopic gastrostomy feedings. Periodic examination and documentation of the distance of the balloon from the skin should be performed to document the position of the tubes or any inadvertent migration of the tubes. The use of Foley catheters as permanent replacement tubes should be considered medically inappropriate.

Association of type 2 diabetes and colon adenomas.

INTRODUCTION: Type 2 diabetes mellitus (DM) is associated with hyperinsulinemia, which may lead to increased risk of carcinogenesis by increasing insulin-like growth factor-1 level. In this study, we sought to determine the association between type 2 DM and colon adenomas. METHODS: In this retrospective case-control study, all the colonoscopies performed in an urban medical center during a 3-year period were reviewed. Patients with adenomatous polyps were considered as cases (n = 261). Age- and sex-matched controls with a 2:1 ratio were selected (n = 522). Among diabetic subjects, the association of different anti-diabetic medications and HbA1C level with high-risk adenoma features was analyzed. RESULTS: Type 2 DM was significantly associated with colon adenomas (odds ratio (OR) = 1.45, 95% confidence interval (CI) = 1.05-2.01, p = 0.024). Exposure to insulin (OR = 1.734, 95% CI = 1.13-2.65, p = 0.013) and thiazolidinediones (OR = 2.83, 95% CI = 1.28-6.26, p = 0.01) was associated with developing adenomas. Neither the type of antidiabetic medication nor the level of HbA1C was a predictor for high-risk adenomas. Smoking (OR = 1.47, 95% CI = 1.07-2.02, p = 0.02), use of aspirin (OR = 1.59, 95% CI = 1.15-2.20, p = 0.005), and statins (OR = 1.54, 95% CI = 1.13-2.10, p = 0.007) appeared to increase the risk of adenomas. CONCLUSION: This study shows a significant association between type 2 DM and colon adenomas. Establishing this association may lead to inclusion of diabetic patients in the high-risk group for developing colorectal cancer.

Does the handling time of unrefrigerated human fecal specimens impact the detection of Clostridium difficile toxins in a hospital setting?

BACKGROUND: The stability of Clostridium difficile toxins is an important factor in determining the accuracy of the enzyme immunoassay (EIA). The Centers for Disease Control has stated that C. difficile toxins may become undetectable in unrefrigerated stool specimens within 2 h after collection. PURPOSE: The purpose of our study was to determine how the unrefrigerated handling time of human fecal specimens affects the results of C. difficile infection (CDI) testing. METHODS: A retrospective review of CDI testing with Premier™ Toxins A and B kit was conducted in northern New Jersey, USA. Stool collection times and receiving times were recorded for each specimen. The unrefrigerated handling time was calculated for each. RESULTS: A total of 1126 fecal specimens were submitted. We excluded 72 fecal specimens due to incomplete documentation. We included 1054 fecal specimens collected from 636 hospitalized patients. A total of 132 out of 1054 specimens (12.5%) tested positive for C. difficile toxins. Nine hundred and fifty-four specimens were unrefrigerated for 13 h or less, of which 127 (13.3%) tested positive. Five (5%) of the 100 specimens that were unrefrigerated for more than 13 h tested positive (p = 0.02). CONCLUSION: C. difficile toxins can still be detected up to 13 h after collection in unrefrigerated human fecal specimens. However, fecal specimens should be processed according to the current recommendations to ensure the reliability of EIA testing until the results of our study are confirmed with prospective studies.

Autoimmune pancreatitis: case series and review of the literature.

Autoimmune pancreatitis (AuP) is a chronic pancreatic inflammation secondary to an underlying autoimmune mechanism. After early reports of a particular type of pancreatitis associated with hypergammaglobulinemia, others asserted that there is an autoimmune mechanism involved in some patients with chronic pancreatitis. In 1995 AuP was first described as a distinct clinical entity. Since then, there have been many documented cases of AuP in Japan, and now, perhaps due to increased awareness, more cases are being reported in Europe and the United States. Herein we present our experience with 3 cases of AuP and we review the relevant literature. These 3 cases demonstrate the difficulties that exist in making the diagnosis of AuP and the impact that the diagnosis can have on patient management.

Impact of patient education on quality of bowel preparation in outpatient colonoscopies.

BACKGROUND: High-quality bowel preparation is essential for successful outpatient colonoscopy. Currently, the rate of adequate bowel preparation for outpatient colonoscopy in the USA is low. Patients often fail to adhere to recommended preparation instructions. Limited literature exists on evaluating educational intervention as a means of improving the quality of bowel preparation prior to outpatient colonoscopy. OBJECTIVE: Our objective was to determine the effect of an educational intervention on the quality of outpatient colonoscopy preparation. The secondary objective was to determine whether the quality of bowel preparation improves overall colonoscopy outcomes as measured by rate of polyp detection and caecal intubation time. METHODS: A single-blinded, prospective, randomised, controlled trial was conducted in two inner-city gastroenterology clinics in the USA. One hundred and sixty-four subjects were enrolled and randomly assigned to one of two groups. The control group subjects received verbal and written instructions for colonoscopy. The intervention group subjects received the same instructions and were then asked to answer a questionnaire. The subjects' responses were reviewed and an additional explanation of the preparation process provided. An attending gastroenterologist determined the quality of each bowel preparation at the time of colonoscopy using the Universal Preparation Assessment Scale. RESULTS: The educational intervention had no impact on the overall quality of bowel preparation (P=0.12). However, the type of food (liquid vs solid) consumed during the 24 hours prior to the procedure (P=0.04) and the time since the last solid meal (P=0.03) did have an impact on preparation quality. Other significant factors included elapsed time to first bowel movement from the initiation of bowel preparation (P=0.05) and age younger than 55 (P=0.02). Adequate bowel preparation was associated with shorter total procedure (P=0.001) and caecal intubation (P=0.01) times. CONCLUSION: Our study failed to demonstrate any effect of an educational intervention on the quality of colonoscopy preparation. However, adherence to simple dietary instructions did have a significant impact on the quality of bowel preparation. Adequate bowel preparation was associated with shorter procedure time and caecal intubation time.
