RESUMEN
BACKGROUND AND AIMS: People with a strong family history of common (so-called 'sporadic') colorectal cancer are generally advised to undergo colonoscopic screening, but the starting age for this is unclear. An audit was performed to study the age-related yield of screening colonoscopy in this risk group. METHODS: A prospective audit of the outcome of screening colonoscopy was performed on a cohort of 232 people with a strong family history of common colorectal cancer. All were registrants in a familial bowel cancer service solely because of their family medical history. They had no bowel symptoms and no prior endoscopic investigation of the large bowel. RESULTS: Neoplastic lesions were detected by using colonoscopy in 33 participants. In 27 participants, the major lesion was a small tubular adenoma, four had an advanced adenoma and two had cancer. More neoplastic (P= 0.02) and advanced neoplastic (P= 0.03) lesions were found in those patients aged > or = 50 years. Only one advanced adenoma was detected in a participant below the age of 50 years. CONCLUSION: The yield from screening colonoscopy in young people (< 50 years) with a strong family history of common colorectal cancer is low, placing doubt on the need for colonoscopic screening before the age of 50 years.

Progressive inhibition of neuromuscular structures (PINS) is a technique that can be included in the osteopathic manipulative treatment repertoire. It relies on knowledge of anatomy and neuromuscular physiologic features as well as on standard forms of osteopathic palpatory diagnosis and treatment. It is a variant of the inhibition technique that has been taught as an osteopathic manipulative technique for many years, and it bears some resemblance to other manual medicine techniques. The emphasis of the approach is the determination of the alteration of the tissues due to dysfunction, delivering treatment based on palpatory evaluation and patient feedback. Two related points are initially chosen, followed by a progression from one to the other. Relationships to similar techniques are also discussed. Theoretical as well as selected practical applications are presented.

The concept that a bioartificial device could compensate for the loss of hepatic function and thus improve the outcome of acute liver failure (ALF) was first suggested more than three decades ago. Currently, and reflecting renewed interest in this possibility, three such devices are undergoing clinical evaluation. Each has been shown to perform metabolic functions normally performed by the liver, thus affecting the serum biochemistry of patients with ALF. However, despite potential merit, these devices have not yet been shown to improve the outcome of patients with ALF. Also, some major safety issues remain to be resolved, in particular the risk of transmission of unknown zoonoses to man.
