Rare presentation of renal cell cancer as dysphagia: a case report.

Background: Metastasis from distal solid organs to the esophagus is very rare. Renal cell cancer with esophageal metastasis is extremely rare. We present the first case report of undiagnosed renal cell cancer presenting as dysphagia.

Choledocholithiasis in African American and Hispanic patients: a comparison between painless presentation and classical biliary pain with regards to clinical manifestations and outcomes.

Choledocholithiasis (CDL) usually presents with biliary pain. Painless CDL is also known to occur, especially in the elderly. The purpose of this study is to determine whether the mode of presentation (painful vs.

Safety and efficacy of colonoscopy in the elderly: experience in an innercity community hospital serving African American and Hispanic patients.

Data regarding safety and efficacy of colonoscopy in elderly African American and Hispanic patients is scarce. We designed our study to determine the safety and efficacy of colonoscopy in this population. We retrospectively reviewed records of 1530 patients, who underwent colonoscopy over a nine-year period.

Natural history of Mallory-Weiss tear in African American and Hispanic patients.

The aim of this study was to determine the natural history of Mallory-Weiss tear (MWT) in African American and Hispanic patients. We retrospectively reviewed medical records of all patients with acute upper gastrointestinal bleeding over a 10-year period. Endoscopic diagnosis of MWT was made in 12% (n = 698) of all patients with acute upper gastrointestinal bleeding.

Endoscopic ultrasound identifies synchronous pancreas cystic lesions not seen on initial cross-sectional imaging.

Objectives: A retrospective review conducted to determine the utility of endoscopic ultrasound (EUS) examination of the pancreas after initial pancreatic cyst detection with cross-sectional imaging.

Methods: A retrospective review of 145 patients referred for EUS for evaluation of pancreas cystic lesions. Initial cross-sectional imaging reports were reviewed and compared to subsequent EUS findings.

Patient preferences after endoscopic ultrasound with fine needle aspiration (EUS-FNA) diagnosis of pancreas cancer: rapid communication valued over long-term relationships.

Background: Endoscopic ultrasound with fine needle aspiration (EUS-FNA) is used for the diagnosis of pancreatic malignancy. However, there are limited data as to patient preferences regarding the delivery of cancer diagnoses.

Objective: This study aimed to assess if patients had met the endosonographer before their EUS, their suspicion of having cancer, and whether they would like the cytology results given to them by their referring physician (with whom they had a previous relationship) or the endosonographer.

Littoral cell angioma of the spleen diagnosed by endoscopic ultrasound-guided fine-needle aspiration biopsy.

Littoral cell angiomas are uncommon primary vascular neoplasms that arise from the sinusoidal lining or littoral cells of the splenic red pulp, and hence are unique to the spleen. We report a case of littoral cell angioma in 34-year-old woman, which was diagnosed by endoscopic ultrasound-guided fine needle aspiration biopsy (EUS-FNAB). The cytologic features of littoral cell angiomas have been described only in three previous case reports, one of which was a bench-top aspirate.

Drug-induced cholestasis.

Recent progress in understanding the molecular mechanisms of bile formation and cholestasis have led to new insights into the pathogenesis of drug-induced cholestasis. This review summarizes their variable clinical presentations, examines the role of transport proteins in hepatic drug clearance and toxicity, and addresses the increasing importance of genetic determinants, as well as practical aspects of diagnosis and management.

Pancreatic and Gastric Plasmacytoma Presenting with Obstructive Jaundice, Diagnosed with Endoscopic Ultrasound-Guided Fine Needle Aspiration.

Pancreatic plasmacytoma is a rare disorder which may present with obstructive jaundice. Only eighteen cases have been reported in the English language literature. We present the first case of pancreatic plasmacytoma and gastric plasmacytoma diagnosed with endoscopic ultrasound-guided fine needle aspiration (EUS-FNA).

EUS-guided FNA of solid pancreatic masses: a prospective, randomized trial comparing 22-gauge and 25-gauge needles.

Background: There is a lack of prospective, randomized studies comparing the diagnostic yield and complication rates of 22-gauge and 25-gauge needles during EUS-FNA of solid pancreatic masses.

Objectives: Our primary aim was to compare the diagnostic yield of 22-gauge and 25-gauge needles. Secondary aims included determining the number of needle passes performed, ease of needle passage, and complications.

Clinical significance of incidental colorectal wall thickening on computed tomography scan in African-American and Hispanic patients.

We sought to assess the significance of an incidental finding of colorectal wall thickening (CRWT) on computed tomography (CT) scan in African-American and Hispanic patients. We retrospectively reviewed charts of African-American and Hispanic patients from January 1994 to December 2005. Those patients were included in whom the colonoscopy was performed due to incidental CRWT on CT scan.

Fecal incontinence in older patients.

Fecal incontinence (FI), the involuntary passage of fecal material through the anus, is a common medical problem in older people, especially in frail older nursing home residents. FI is often associated with urinary incontinence. Severe constipation leading to fecal impaction, laxative abuse, diarrhea, cognitive impairment, senescence, and neuromuscular disorders including autonomic neuropathy, are among the leading causes of FI in older patients.
