A Pain in the Butt: Hemorrhoids, Fissures, Fistulas, and Other Anorectal Syndromes.

Painful and bothersome anorectal syndromes can be a diagnostic and therapeutic challenge for clinicians because structural and functional abnormalities may often coexist and require a multidisciplinary approach to management. Although it is often difficult to attribute all of a patient's anorectal symptoms to a singular disorder with definitive intervention and cure, improving quality of life, treating coexistent conditions such as functional constipation and/or defecation disorders, addressing psychological comorbidities if present, and confirming there is no evidence of inflammatory or malignant conditions are top priorities.

Diagnostic Evaluation of Gastric Motor and Sensory Disorders.

Disorders of gastric motor and sensory function affect 10%-20% of the world's population and adversely impact nutrition, quality of life, work productivity, and health care costs. Classifying these disorders can be challenging given the heterogeneity of symptom presentation, the presence of symptoms unexplained by endoscopic, radiographic and/or laboratory evaluation, and overlap with other luminal gastrointestinal disorders. Accurately diagnosing these highly prevalent disorders relies upon an understanding of epidemiology and risk factors, the ability to take a careful clinical history focused on symptoms, and the presence of predisposing medical, surgical, and psychological conditions.

Evaluation and Treatment of Constipation in the Geriatric Population.

Chronic constipation affects one-third of the US population and occurs disproportionately in the elderly and female individuals, increasing in older individuals who are institutionalized. This condition has a significant impact on health care costs and quality of life. Clinicians need to consider primary as well as secondary causes of constipation in elderly individuals because the cause is often multifactorial.

YouTube™ as a Source of Instructional Videos on Bowel Preparation: a Content Analysis.

Instructional videos on bowel preparation have been shown to improve bowel preparation scores during colonoscopy. YouTube™ is one of the most frequently visited website on the internet and contains videos on bowel preparation. In an era where patients are increasingly turning to social media for guidance on their health, the content of these videos merits further investigation.

C-reactive protein and high-sensitivity C-reactive protein: an update for clinicians.

The measurement of C-reactive protein (CRP) using both standard and high-sensitivity CRP (hs-CRP) assays is becoming common in clinical practice. This article addresses the causes of CRP elevation and the use of different CRP assays in internal medicine, including cardiology, gastroenterology, rheumatology, infectious diseases, and oncology. We focus on the recent medical literature on the use of hs-CRP in cardiovascular disease risk stratification and management, including updated screening guidelines on the use of hs-CRP, such as those issued in 2009 by the Canadian Cardiovascular Society.

Lubiprostone: evaluation of the newest medication for the treatment of adult women with constipation-predominant irritable bowel syndrome.

Irritable bowel syndrome (IBS) is a chronic disorder that affects primarily female patients and is thought also to afflict approximately 7%-10% of the population of the Western World. Although bowel habits may change over the course of years, patients with IBS are characterized according to their predominant bowel habit, constipation (IBS-C), diarrhea (IBS-D), or mixed type (IBS-M), and treatments are focused toward the predominant symptom. Current treatments for IBS-C have included fiber, antispasmodics, osmotic and stimulant laxatives, and the now severely limited 5-HT(4) agonist tegaserod.

Personality traits and impaired health-related quality of life in patients with functional gastrointestinal disorders.

Background & Aims: Negative affectivity and social isolation (Type D personality) are personality traits associated with poor health-related quality of life (HRQoL). We hypothesized these traits would be associated with impaired HRQoL and increased gastrointestinal symptom severity in functional gastrointestinal disorders.

Methods: Data were collected from patients undergoing breath testing.

Emerging drugs for chronic constipation.

Chronic constipation (CC) is one of the most common functional gastrointestinal disorders. CC is estimated to affect up to 27% of the North American population. Although not life-threatening, CC can have profoundly negatively affects on quality of life and result in significant economic burden in terms of both direct and indirect healthcare costs.

Impact of anal incontinence on psychosocial function and health-related quality of life.

The relationship among the frequency of anal incontinence (AI), psychosocial factors, and health-related quality of life (HRQOL) was evaluated. Consecutive patients (n=280) completed a bowel symptom questionnaire, the Symptom Checklist 90 -- Revised (SCL 90-R), and an assessment of HRQOL. Group 1 had no incontinence, Group 2 had AI less than once per week, and Group 3 experienced AI more than once per week.

Autoimmune gastrointestinal dysmotility treated successfully with pyridostigmine.

Background & Aims: Autoimmune gastrointestinal dysmotility (AGID) is a limited form of autoimmune autonomic neuropathy occurring idiopathically or in a paraneoplastic context. This disorder is considered rare, but is underrecognized as a cause for GI dysmotilities of varying anatomic extent, severity, and duration. We describe the diagnosis and management of an instructive case.
