Effects of posture on gastro-oesophageal reflux.

Continuous oesophageal pH measurements have been used to assess the influence of posture (lying, sitting, bed-up) on gastro-oesophageal reflux. The percentage of time during which oesophageal pH was below 5 and the number of reflux episodes was significantly reduced when patients were in bed-up position than when sitting or lying. There was no significant difference when sitting and lying positions were compared. The results suggest that by adopting the bed-up position (elevation of the head end of the bed with blocks of 28 cm), the patient will have a symptomatic benefit, the frequency of reflux is decreased, and acid clearing is improved.

Gastric secretion, gastroesophageal reflux and esophagitis.

Neither gastroesophageal reflux nor esophagitis were found to have a clear-cut relationship with gastric secretory output. Patients with esophagitis had significantly longer periods of reflux than those without esophagitis. It is concluded that the important factor in the genesis of esophagitis is the duration of contact between the esophageal mucosa with gastric contents rather than gastric secretory output.

Preliminary communications.

The effects of pentazocine on colonic motor activity were studied in five normal subjects, five patients with irritable bowel syndrome, and five patients with diverticular disease. The drug decreased intraluminal colonic pressures in all patients but one. Since morphine, which increases intraluminal colonic pressures, is contraindicated in patients with abdominal pain of colonic origin (diverticular disease, irritable bowel syndrome), we suggest that pentazocine may be a useful drug in such cases.

Oesophageal acid clearing: one factor in the production of reflux oesophagitis.

Oesophageal acid clearing has been measured by counting the number of swallows needed to raise the lower oesophageal pH from 1.5 to 5.0 after instilling 15 ml 0.1 N hydrochloric acid. Normal subjects all had a result less than 12, as did asymptomatic patients with hiatal hernias. Patients with symptomatic gastrooesophageal reflux tended to have abnormal acid clearance, as did those with oesophageal motility disorders. Acid clearance correlated well with the mean duration of spontaneous episodes of acid reflux during 15-hour continuous recordings of lower oesophageal pH. Abnormal acid clearance was improved by raising the bedhead, by medical treatment for oesophagitis, and by metoclopramide. We conclude that abnormal acid clearing may result from disturbed oesophageal motility and render patients with these disorders susceptible to reflux oesophagitis. However, it also seems that gastrooesophageal reflux may lead to impaired acid clearance, both by creating abnormal motility and by effects on the oesophageal wall, and thus lead to a ;vicious-spiral' oesophagitis. In treating gastrooesophageal reflux, attention must be paid to improving acid clearance.

Metoclopramide in gastrooesophageal reflux.

In 30 patients with gastrooesophageal reflux, intravenous metoclopramide (Maxolon) has been shown to increase the gastrooesophageal sphincter pressure. The rise is dose-related until a maximum pressure, proportional to the resting sphincter tone, is reached. The effect is reversed by atropine. Peristaltic waves are increased in pressure by metoclopramide.In 18 patients with gastrooesophageal reflux intravenous metoclopramide diminished the frequency of reflux episodes and increased the rate at which the oesophagus emptied itself of an acid load.

Smoking and gastro-oesophageal reflux.

Gastro-oesophageal sphincter pressure and intraoesophageal pH has been studied in 25 chronic smokers who complained of heartburn. Smoking a cigarette invariably caused a fall in sphincter pressure, and pH measurements showed an increased tendency for reflux to occur while smoking. When lower oesophageal pH was measured overnight one-third of all reflux episodes occurred while the patients were smoking, and reflux was seen during the smoking of two-thirds of all the cigarettes consumed. It is concluded that cigarette smoking is a common reversible cause of gastro-oesophageal reflux.

Congenital glenoid dysplasia: case report in two consecutive generations.

Congenital glenoid dysplasia is a rare congenital condition of the shoulder. We report the case of a 6-year-old girl that was referred to our institution for restricted motion of both shoulders. Radiological examination revealed bilateral glenoid dysplasia. At the time of the child's examination, her mother also complained of shoulder stiffness; radiographs of her shoulders were taken and revealed that she too had glenoid dysplasia. Congenital glenoid dysplasia results from failure of development of the inferior ossification center of the glenoid fossa. Shoulder stiffness is the primary resultant disability, although it is variable. Our case is notable because we identified the dysplasia in two successive generations of the same family, although the mother was unaware she had the condition.

Apoptosis in human embryo development: 2. Cerebellum.

We analysed the spatial and temporal distribution of apoptosis in human cerebellum development, during embryonic and fetal periods. Cerebella excised from two human embryos (8 weeks old) and eight fetuses (12-22 weeks old), were paraffin embedded and serially sectioned. Apoptotic cells were identified by propidium iodide staining, and TUNEL. In addition, immunohistochemistry for suicide receptor Fas(APO-1/CD95) was performed. We determined the distribution and percentage of apoptotic cells as well as Fas(APO-1/CD95)-positive cells in different regions and stages of development. Apoptotic cells were seen in both proliferative zones and postmitotic regions along the migratory pathways as well as in the developing cerebellar cortex in all examined stages. The Fas(APO-1/CD95) immunoreactivity was present in all examined stages in a small population of apoptotic cells: either neuroblasts or differentiated cells in postmitotic zones. These findings suggest that apoptosis drives the selection of the cells which are committed to differentiate during the early stages of cerebellar development. The differences between apoptotic cells distribution and Fas receptor expression suggest that cell selection is driven by different apoptotic pathways.
