The purpose of this paper is to describe our experience with a new technique of colonic manometry catheter placement using fluoroscopic guidance. Between 2000 and 2004, 44 colonic manometry catheters were placed with primary fluoroscopic guidance in 38 patients (25 males; median age, 7 years; range, 0.4-31 years) with severe defecation disorders. Fourteen colonoscopic placements were reviewed to compare the different procedures. ⋯ Significantly longer fluoroscopic exposure was required for fluoroscopic compared to colonoscopic placement (P=0.004). In conclusion, placement of colonic manometry catheters with primary fluoroscopic guidance is feasible in children. An important disadvantage of the fluoroscopic methodology is the prolonged fluoroscopic exposure time.

Clinical Trial
Proton pump inhibitors improve acid-related dyspepsia in gastroesophageal reflux disease patients.
It has been reported that proton pump inhibitors are more effective than H2 receptor antagonists in patients with functional dyspepsia. Dyspeptic symptoms that respond to proton pump inhibitors are classified as acid-related dyspepsia. A new questionnaire for assessing gastroesophageal reflux disease (GERD), the Frequency Scale for Symptoms of GERD, covers the 12 most common symptoms of GERD patients. ⋯ Sixty-eight GERD patients receiving proton pump inhibitor therapy completed the questionnaire before and after treatment for 8 weeks. There is a significant positive correlation between reflux symptoms and acid-related dyspepsia before and after therapy (r = 0.569 and r = 0.569; both P's < 0.001) and acid-related dyspepsia in patients with both nonerosive and erosive GERD. We conclude that GERD patients suffer not only from reflux symptoms, but also from acid-related dyspepsia, and proton pump inhibitors improve both types of symptoms.

Controlled Clinical Trial
Transcutaneous electrical nerve stimulation (TENS) improves upper GI symptoms and balances the sympathovagal activity in scleroderma patients.
To assess the impact of transcutaneous electrical nerve stimulation (TENS) at gastrointestinal (GI) acupoints on GI symptoms and quality of life in scleroderma patients, 17 patients filled out SF-36 and GI symptom questionnaires before the electrocardiogram was recorded for two intervals: baseline and TENS. At home, patients applied TENS for 14 days, then were reassessed. ⋯ Prolonged TENS application normalized the sympathovagal balance (P=0.04), decreased GI symptom scores (P=0.02) and increased the physical functioning score (SF36), which strongly correlated with the change in the sympathovagal balance (r=0.6, P=0.02). In conclusion, TENS at GI acupoints offers a potential option in the treatment of upper GI symptoms, but further study is necessary.

Scurvy is a nearly-forgotten disease in developed countries where adequate nutrition is easily available. It still may occur, however, when, for a variety of reasons, people fail to eat a diet containing adequate vitamin C. We report the case of a 52-year-old patient with depression who developed scurvy.

Although many randomized controlled trials (RCTs) have been performed to date in the field of the treatment for hepatocellular carcinoma (HCC), there has not been any detailed analysis or evaluation of the quality of these RCTs. This study analyzed the characteristics and quality of RCTs investigating the treatment of HCC. A MEDLINE search was performed to identify prospective RCTs investigating HCC treatment published between 1991 and 2005. ⋯ Many RCTs on the treatment of HCC have been performed all over the world, especially in Asia and Europe. The quality of these RCTs is, however, unsatisfactory and most of the RCTs are still inadequately performed. High-quality RCTs are needed to establish common therapeutic guidelines.
