Bile acid malabsorption as a cause of hypocholesterolemia seen in patients with chronic pancreatitis.
A determination of caloric consumption based on a dietary survey table, fat and cholesterol intake, and analyses of fecal fatty acids and neutral sterols, and bile acid analysis (gas chromatographic method) were conducted on 33 subjects (including 17 patients with chronic pancreatitis and 16 normal controls). The factors related to hypocholesterolemia in chronic pancreatitis (CP) patients were investigated and the following conclusions were obtained: (1) The total caloric intake and fat consumption by the CP patients were significantly lower with the exception of cholesterol consumption. (2) Significant increases were noted in fecal fat, neutral sterols, and bile acid excretion by the CP patients. (3) A significant positive correlation was noted between the total cholesterol and body mass index (BMI), reaffirming that the cholesterol level can be used as an indicator of nutritional status. (4) A significant negative correlation was noted between the serum total cholesterol and fecal bile acid excretion. These findings indicate that CP patients suffer from neutral sterol malabsorption, in addition to dietary fat maldigestion and bile acid malabsorption. Furthermore, bile acid malabsorption is cited as a factor in the development of hypocholesterolemia in CP patients.

Effect of omeprazole on changes in gastric and upper small intestine pH levels in patients with chronic pancreatitis.
Gastric and upper small intestine pH levels were measured continuously over 24 hours in patients with chronic pancreatitis, and values obtained before and after the administration of omeprazole were compared. Additionally, omeprazole was administered for 2 weeks and the fecal excretion of fat was compared before and after drug therapy. Postprandial gastric pH levels, initially 2.9 to 3.2, increased by 1.6 to 2.1 after treatment. Postprandial upper small intestine pH levels, initially 5.1 to 5.5, increased by 0.7 to 1.0. The lowest pH value of the upper small intestine was 2.2 to 2.4 postprandially; this was increased by > 1.0 after omeprazole, and the amplitude of pH variation was reduced. The cumulative proportions of intraintestinal pH strata of < or = 3, < or = 4, or < or = 5, and higher, initially being 16.4% to 17.1%, 27.4% to 31.7%, and 52.6% to 57.8%, respectively, were remarkably improved after drug treatment. Gastric pH and upper small intestine pH levels showed a positive correlation; an increase in gastric pH levels by 2 corresponded to an increase in small intestine pH levels by 1. After omeprazole administration, mean fecal excretion of fat was decreased to 4.1 +/- 2.6 g/d (range, 1.1 to 9.8 g/d) from 6.5 +/- 3.9 g/d (range, 1.6 to 13.5 g/d). Decreases in excretion of fat averaged 3.4 g/d (range, 2.2 to 4.5 g/d) in patients with steatorrhea. It was concluded that steatorrhea due to chronic pancreatitis can be improved to some extent by improving upper small intestine pH levels following the elevation of gastric pH levels after administration of omeprazole.

Clinical analysis of multiple primary malignancies of the hypopharynx and esophagus.
PURPOSE: Because the capability to control squamous cell carcinomas of the head and neck has improved recently, the phenomenon of multiple primary malignancies of that region is now recognized with increasing frequency. We reviewed cases of multiple primary squamous cell carcinomas of the hypopharynx and esophagus with regard to their frequency, incidence, and prognosis. PATIENTS AND METHODS: We reviewed 104 cases of hypopharyngeal cancer to determine (1) if and when esophageal cancer occurred, (2) the classification of multiple tumors as metachronous or synchronous, and (3) tumor histology. RESULTS: In most cases of the metachronous type, esophageal cancer followed hypopharyngeal cancer within less than 3 years. Most cases of hypopharyngeal cancer were at an advanced stage, in contrast to esophageal cancer, which were all early stage. These cases had a poor prognosis despite various treatments causing local disease to be well controlled. Endoscopic esophageal mucosal resection was found to be an effective treatment for esophageal cancer, especially in superficial types. CONCLUSIONS: The prognosis and mild systemic damage after endoscopic esophageal mucosal resection compare favorably with surgery, radiation, or systemic chemotherapy.

Effects of FL-386 on faecal lipid excretion in humans.
A newly synthesized inhibitor of pancreatic lipase and micelle formation, FL-386, was administered at a dose of 400 mg (in the diet, for seven consecutive days) to nine healthy adult volunteers, and changes in faecal mass, frequency of defaecation, and properties of the stools were observed. High performance liquid chromatography and gas-liquid chromatography were used to analyse the faeces for short-chain carboxylic acids, neutral sterols, bile acids, fats and hydroxyfatty acids. FL-386 had little effect on the amounts and composition of short-chain carboxylic acids, neutral sterols, and bile acids excreted, nor did it produce changes in the composition of fatty acids, or the percentages of hydroxyfatty acids in the stool. However, in those patients treated with FL-386, the faecal mass was increased, and stools were softer and contained increased amounts of fatty acids. The compound did not produce particularly fatty stools. It was concluded that FL-386 induces slight disturbance in the digestion and absorption of dietary lipids.

Effect of an alpha-glucosidase inhibitor on intestinal fermentation and faecal lipids in diabetic patients.
Eight non-insulin-dependent diabetes mellitus patients, in whom oral hypoglycaemic agents were not effective, were treated with an alpha-glucosidase inhibitor, AO-128 (0.9 mg/day) for 6 months. After 6 months of treatment there was a statistically significant decrease in the blood glucose level 1 and 2 h postprandially. The 2 h blood glucose level was also significantly reduced after 2 months' treatment. The insulin and HbA1c levels after 2 and 6 months' treatment were lower than those before administration. Faecal weight, the frequency of bowel movements, the ratio of hydroxy fatty acids to total fatty acids, and faecal short-chain carboxylic acid content were all increased significantly during treatment. The initially hard stools became normal or soft, although no actual diarrhoea developed. Both faecal bile-acid excretion and the ratio of primary bile acids to total bile acids were increased significantly after 2 months, but they showed some recovery towards the pretreatment levels after 6 months' treatment. There was no distinct change in neutral sterol and fatty acid excretion. Breath hydrogen excretion showed a slight increase after treatment. These results suggest that intestinal fermentation was promoted and the intestinal transit time was shortened by AO-128 administration.

Changes in plasma fatty acid profile in Japanese patients with chronic pancreatitis.
The serum zinc, prealbumin, retinol-binding protein and carotene concentrations and the plasma fatty acid composition were determined to assess the nutritional condition of 24 patients with chronic pancreatitis compared with that of 20 healthy controls. The daily food intake and faecal fat excretion of the two groups were also measured. In the chronic pancreatitis group, the calorie and fat intakes were significantly lower than those of the controls. Serum levels of zinc, prealbumin and carotene were also significantly lower than those of the controls. Percentages of plasma linoleic and arachidonic acids were low, while percentages of palmitoleic acid, eicosapentaenoic acid and docosahexaenoic acid were high. Fish oil intake correlated negatively with plasma linoleic acid concentration (P < 0.05). The above results indicate that the relatively high intake of fish oil and the relatively low intake of dietary fat in Japanese patients with chronic pancreatitis with a mild degree of steatorrhoea results in an abnormally low plasma level of linoleic acid.

Effect of intravenous administration of EM523L on gastric emptying and plasma glucose levels after a meal in patients with diabetic gastroparesis: a pilot study.
EM523L, a newly developed erythromycin derivative, has a powerful motilin-like biologic effect and no antibacterial activity. In this pilot study, EM523L was administered to six patients with diabetic gastroparesis, and its effects on gastric emptying function and the change in plasma glucose levels after eating were examined. Gastric emptying was evaluated by the simultaneous measurement of solid and liquid food intake using 99mTc-Sn-colloid and acetaminophen, respectively. Eggs labeled with isotope and milk with added acetaminophen were used as the test meals. The change in plasma glucose level after ingestion of the test meal was also examined. A total of 2 mg of EM523L dissolved in 100 mL of physiologic saline was administered by intravenous infusion over a period of 15 minutes after ingestion of the test meal. The retention rates of the gastric isotope decreased following the administration of EM523L at 20 to 120 minutes after ingestion of the test meal. Plasma acetaminophen concentrations following EM523L administration increased at 20 and 30 minutes. The plasma glucose levels showed an increase at 30 to 60 minutes after eating--the result of improved gastric emptying function. From these results, we concluded that intravenous administration of EM523L in patients with severe diabetic gastroparesis promotes gastric emptying of a solid and liquid meal and, as a result, plasma glucose levels increase after eating.

Pheochromocytoma with multiple islet cell carcinoma.
We reported a rare case of a 17-year-old female with pheochromocytoma associated with multiple islet cell carcinoma. Pheochromocytoma was identified in the right adrenal gland. Multiple pancreas tumours were demonstrated unpredictably in the diagnostic imaging of the pheochromocytoma. No other endocrinological neoplasm was observed in the pituitary, thyroid and parathyroid gland. The patient underwent right adrenalectomy and total pancreatectomy. Pheochromocytoma was benign, however, pancreas tumours were non-functioning islet cell tumours and histologically malignant. This combination is assumed to represent a mixed form of multiple endocrine neoplasia (MEN) 1 and MEN 2.

Short-chain carboxylic acid in the feces in patients with pancreatic insufficiency.
Short-chain carboxylic acids in the feces of 12 patients with chronic pancreatitis having steatorrhea and 18 healthy subjects were determined by high-performance liquid chromatography. The fecal amount of the patients with chronic pancreatitis was increased to about twice that of the control, and the fat in the feces increased to eight times. The excretion of short-chain carboxylic acids increased to about three times. The short-chain carboxylic acid concentration regarded as derived from protein or amino acid, such as iso-butyrate, isovalerate, and n-valerate, was significantly increased in patients with chronic pancreatitis. From the above results, our data suggest that there is maldigestion of protein besides that of carbohydrate. And we confirmed that these data are an in-vivo illustration of the phenomena which have been studied in-vitro experiments, when fecal bacteria were incubated with peptide or amino acids as a substrate.

Fat-soluble vitamins in patients with chronic pancreatitis (pancreatic insufficiency).
The fat-soluble vitamin contents in the blood (vitamins A, D, E, and K) were determined in 12 patients with chronic pancreatitis (exocrine pancreatic insufficiency) and in 20 healthy adults by the HPLC and CPBA methods. In addition, 9 g (3 g x 3 times) of high potency pancreatin was given to 11 patients with chronic pancreatitis (CP) for approximately 1 month and changes in the blood fat-soluble vitamin levels were evaluated before and after the treatment. The major component of vitamin E was alpha-tocopherol. The mean alpha-tocopherol level in normal individuals was 0.97 mg/dl, while it was significantly reduced in CP patients (p < 0.01). The vitamin A, D, and K levels had also been reduced in patients with CP, but the differences were not significant (although some patients in this group exhibited significant reductions from the levels of normal individuals). Only the blood vitamin E level showed a significant correlation with the fecal fat excretion or the fat absorption rate. None of the patients with CP exhibited an overt fat-soluble vitamin deficiency (i.e., the deficiency of fat-soluble vitamins was at a subclinical level). These results indicated that CP patients suffer from a latent fat-soluble vitamin deficiency and that the vitamin E level is closely related to a dysfunction of fat digestion. It was suggested that the dietary intake of each fat-soluble vitamin should be evaluated further.

Study of gastric emptying in patients with pancreatic diabetes (chronic pancreatitis) using acetaminophen and isotope.
The gastric emptying function tests were carried out in eight patients with pancreatic diabetes, who were classified into two groups according to the coefficient of variation in the R-R interval in ECG (C.V. R-R) on the normal subjects: < or = the mean - 2SD (the autonomic nerve dysfunction group: AND+ group) and > the mean - 2SD (the autonomic nerve normal group: AND- group). Both the gastric emptying of liquid food by the acetaminophen method and that of solid food by the isotope method were significantly reduced in the AND+ group than in the AND- and normal groups. In addition, a significant correlation was found between the C.V. R-R and the serum acetaminophen concentration (a 45 min value) and the % gastric retention of isotope (a 120 min value). The above results demonstrated that even pancreatic diabetes might be complicated by gastroparesis diabeticorum among autonomic nerve dysfunction. There was a close relation of delayed gastric emptying to the C.V. R-R in ECG or an index of the vagus nerve function.

Meal-related changes in plasma CCK bioactivity in patients with chronic pancreatitis.
In order to clarify whether there is a negative feedback mechanism for CCK secretion, we investigated plasma CCK bioactivity in patients suffering from chronic pancreatitis (CP) according to the characteristics of their pancreatic disease. Basal, meal-stimulated, and integrated release of plasma cholecystokinin (CCK) bioactivity was measured in 24 patients with CP and in 12 healthy controls. The values obtained were compared between the healthy control group and the CP group, and between subgroups of CP patients established on the basis of the presence/absence of several parameters: abnormal gastric emptying, abdominal pain, steatorrhea, pancreatic calcification, insulin-requiring diabetes mellitus, and impairment of pancreatic exocrine functions as indicated by secretin test. A bioassay method using pancreatic acini was used to measure plasma CCK bioactivity. In the control group, plasma CCK bioactivity increased from a basal value of 1.6 +/- 0.7 pmol/L to a maximal increase of 6.6 +/- 4.1 pmol/L, and the integrated CCK release following a test meal was 37.7 +/- 19.3 pmol/L.150 min. In the CP group, plasma CCK bioactivity increased from 1.6 +/- 0.9 pmol/L to a maximal increase of 8.2 +/- 8.7 pmol/L, and the integrated release of CCK was 43.0 +/- 37.7 pmol/L.150 min. None of the differences between them were significant. No significant differences in basal value, maximal increase, or integrated plasma CCK release were noted according to any of the parameters of the CP patients and the control group. Nor was there any correlation between impairment of pancreatic exocrine function and plasma CCK bioactivity. These results provide no evidence of a negative feedback mechanism between pancreatic exocrine dysfunction and CCK secretion.
