Certain patients with inflammatory bowel disease are at heightened risk for the development of colorectal cancer. But researchers have not yet been able to discover markers that can identify these patients.

A 47-year-old woman who recently completed adjuvant chemotherapy for colon cancer has painless cervical lymphadenopathy of 1 to 2 cm. She has no fever, sore throat, cough, or unexplained weight loss, and she denies exposure to ill persons or animals.

ABSTRACT: Screening options for colorectal cancer (CRC) include colonoscopy every 10 years, annual fecal occult blood testing, flexible sigmoidoscopy every 5 years, or double contrast barium enema every 5 years. In white patients at average risk, screening should begin at age 50; in African American patients, at age 45. Colonoscopy is preferred to sigmoidoscopy because it can detect proximal neoplasms and has the longest protection interval. High-risk patients include those with a family history of CRC or adenomas. These persons should begin colonoscopic screening at age 40, or 10 years earlier than the age at which CRC or adenomas were diagnosed in a first-degree relative. Other high-risk patients are those with a personal history of CRC, a genetic syndrome, or inflammatory bowel disease. In patients with CRC, the first follow-up colonoscopy is performed 1 year after surgery. If results are normal, the interval can be extended to every 3 years.

The FDA has approved injectable Acetadote (acetylcysteine)from Cumberland Pharmaceuticals Incto prevent or lessen liver damage resulting from an overdoseof acetaminophen.

As the population ages, physicians are seeing a greaternumber of patients with colorectal disorders. This book combinesan up-to-date survey of the latest basic and clinicalresearch in the field with practical advice for the day-to-daycare of patients with colonic diseases. The first section ofthe book covers current knowledge of normal colorectal physiology.Section 2 discusses the basic disease mechanismsinvolved in colonic disorders and reviews the uses of suchinvestigational tools as colonoscopy, colonic biopsy, anorectalmanometry, ultrasonography, motility measurement,defecography, CT, and MRI. The third section offers a fulldiscussion of the diagnosis and treatment of commoncolonic disorders, including colorectal neoplasia, inflammatorybowel disease, ulcerative colitis, diverticular disease,Crohn disease, constipation, and irritable bowel syndrome.In addition to currently recommended approaches to evaluationand treatment, chapters in this section include discussionof advanced and investigational therapies.

A 72-year-old man complains that he has been losing weightfor the last 2 months. Colon cancer was diagnosed 2 yearsearlier, and the lesion was resected; he did not receive anyadditional therapy at that time. Except for hypertension,which is well controlled with propranolol, the remainder ofthe medical history is unremarkable.

A 52-year-old woman was admitted tothe hospital with progressive shortnessof breath of 2 days’ duration. Bronchialasthma had been diagnosed 6 monthsearlier; inhaled corticosteroids, bronchodilators,and leukotriene antagonistswere prescribed. Despite aggressivetreatment, the patient’s dyspneaand wheezing worsened.

An 83-year-old man complains of weakness, easy fatigability, and poor appetitethat began 4 to 6 weeks ago. He becomes short of breath on his daily walksand has lost about 20 pounds over the last 3 months. He denies nocturia,paroxysmal nocturnal dyspnea, exertional chest pain, fever, cough, melena,and hematochezia. His only GI symptom is occasional crampy abdominal painwith bowel movements.

You routinely order laboratory screeningpanels, including serum liver enzymemeasurements, for nearly everypatient who has a complete physicalexamination or who is seen for any ofa host of other complaints. If you findabnormal liver enzyme levels, your familiaritywith the common causes andthe settings in which they occur mayenable you to avoid costly diagnosticstudies or biopsy.
