No study to date has objectively investigated whether the motor behavior of the small bowel is abnormal in celiac sprue. The purpose of this study was to systematically address this topic by means of intraluminal pressure recordings in a series of such patients. Sixteen subjects (nine adults, seven children, age range 2-69 years) with celiac sprue were recruited and studied while untreated. Manometric examination was carried out for 6 hr during fasting and 3 hr after a meal. Adult celiac patients displayed a significantly (mean +/- SEM) greater frequency of migrating motor complexes in comparison to controls during fasting (4.44 +/- 1.6 vs 2.45 +/- 0.20, P < 0.01), whereas no differences were found in the pediatric group with respect to this variable. Fasting motor abnormalities, chiefly represented by discrete clustered contractions, giant jejunal contractions, and bursts of nonpropagated contractions, were discovered in a high percentage in both groups of celiac subjects (89% in adults and 44% in children, respectively). Similar abnormalities were observed in the postprandial period, especially in adults. In conclusion, patients with celiac sprue frequently display discrete gastrointestinal motor abnormalities, which though perhaps nonspecific may account for several symptoms complained of by such patients.

A series of cases of epilepsy with associated bilateral occipital calcifications (EBOC) without signs of phakomatosis and without any disorders known to produce cerebral calcifications have been reported. It is unclear whether EBOC is an incomplete variant of Sturge-Weber disease (SWD) or if it is a different, as yet undefined encephalopathy. We describe four new cases of EBOC that are different clinically by age of onset, type, course, severity of epilepsy, and associated cognitive deficits but that are linked by similar neuroradiologic findings. Similar to cases described in the literature, there is convincing evidence in favor of the hypothesis that these cases belong to an encephalopathy different from SWD and frequently associated with celiac disease.

Coeliac sprue patients display an increased frequency of malignant neoplasms of the gastrointestinal tract. These neoplasms are chiefly represented by lymphomas, occurring in patients over 50. We describe the onset of a duodenal adenocarcinoma in a young woman with coeliac disease and discuss the unusual features of this case.

We studied the whole colonic motility for 24 hours in controls and in constipated patients. In the patient group we found a significant reduction in the colonic mass movements (6.1 +/- 0.9 vs 2.6 +/- 0.7 controls vs patients, respectively). The constipated patients showed a reduction of the colonic motor activity after the ingestion of a standard meal. Moreover, they showed, compared with controls, a significant reduction of postprandial mass movements. On the other hand we were not able to find the so-called rectal motor complex described by others. In conclusion, we believe that prolonged colonic manometry would become an important step when evaluating the pathophysiology of constipated patients, particularly of those not responding to standard treatment.

Whipple's disease is an uncommon disorder, generally associated with gastrointestinal symptoms; of these, diarrhea is a common feature. We report a case of Whipple's disease associated with chronic constipation which was not diagnosed until after Giardia lamblia infestation had caused diarrhea. To the best of our knowledge this association has not previously been reported. The clinical, laboratory, endoscopic, and manometric aspects are described and discussed.
