Acarbose, an alpha-glucosidase inhibitor, delays absorption of carbohydrate in the gut, thereby lowering postprandial glucose levels. Safety data on this drug have been gathered in a series of studies on animals and in extensive clinical trials in humans. Although an initial long term feeding study in rats showed an excess of renal tumours at very high dosages of acarbose (up to 300 mg/kg bodyweight daily), further evaluation with similar studies in rats, hamsters, and dogs indicated that the problem was related to carbohydrate malabsorption. With adequate glucose intake and in gavage studies, no difference in tumour incidence between placebo- and acarbose-treated groups was seen. From 1976 to 1989, safety data on acarbose were obtained in approximately 8800 patients in 2 separate groups of clinical trials, the Bayer International Clinical Data Pool and the American phase III trials. Almost all adverse experiences, as reported by 56 to 76% of patients on acarbose vs 32 to 37% of patients on placebo, were related to the digestive system and included diarrhoea, flatulence, bloating and nausea. Most symptoms were of mild to moderate intensity and tended to improve with time. In the American trials a small but significant increase in liver transaminases was seen, 3.8% in acarbose-treated patients vs 0.9% in controls together with a 1% increase in anaemia in the acarbose group. Overall, acarbose was well tolerated and the adverse experience profile was clinically acceptable.

This study was carried out between June 1986 and May 1988 in Berlin (West). In cooperation with 5 Pathological Departments, we prospectively recorded every bioptical diagnosis of total/subtotal villus atrophy (group S) or of partial villus atrophy (group SV). In addition, we registered anamnestic, clinical and laboratory findings from these patients. The diagnosis of coeliac disease was considered verified if the patient showed an unequivocal improvement of his clinical conditions and laboratory findings within three months on a gluten-free diet. In total, 42 patients were registered, among them were 29 with mucosal alterations typical for coeliac disease and 13 whose biopsies showed partial villus atrophy. The diagnosis of coeliac disease could be verified in 28 patients, among them one woman with intestinal lymphoma after longstanding untreated coeliac disease. A second patient with complete villus atrophy had intestinal lymphoma but without preceeding coeliac disease. Our findings show that the incidence of coeliac disease in Berlin is 1 out of 2113 newborn children. This figure is similar to the data reported from France, yet being clearly lower than those from Western Ireland, Switzerland and Sweden. Women are affected twice as often as men. 20 out of 28 patients were children under five years of age. The most common symptoms were meteorism/flatulence, recurrent diarrhea, loss of body weight, or inappropriate growth. 70% of the patients suffered from anaemia, the D-Xylose-test was pathological in 92% of the patients.

The delay in diagnosis of 106 patients with adult coeliac disease, diagnosed between 1976 and 1980, was studied. Overall, delay in diagnosis was 11 +/- 10.6 years, being considerably greater in females (12.8 +/- 7.8 years) than in males (3.5 +/- 9.8 years). Most of this delay occurred prior to hospital referral, although that following referral to hospital clinics was still significant (1.8 +/- 4.8 years). The most common presenting complaints were lassitude (75%) anaemia (65%) and flatulence (50%). Typical gastro-intestinal symptoms were relatively uncommon and mild, but when present led to a more speedy diagnosis. It is concluded that, despite advances in modern diagnostic procedures, little progress has been made in hastening the diagnosis of coeliac disease.

A cohort of patients with a histological diagnosis of colorectal carcinoma was enrolled prospectively. All subjects were interviewed by one observer using a structured questionnaire. One hundred and fifty 'young' (under 70 years) and 123 'elderly' (70 years or more) subjects formed the study sample. The elderly patients did not present more frequently as emergencies than the young, but were more often referred to medical or geriatric rather than surgical units (p < 0.01). There was no difference in median overall delay from symptom onset to histological diagnosis between the age groups (19.5 weeks in each). Symptomatic anaemia and nonspecific symptoms were more often the presenting complaint in the elderly subjects (p < 0.05). On direct questioning, there were no differences in symptom reporting with respect to age group for subjects with colonic cancer. For rectal cancer the following symptoms were more common in the young group: tenesmus (odds ratio 4.2; 95% confidence intervals 2.0-10.0), abdominal or rectal pain (4.0; 1.9-10.6), change in flatus production (2.6; 1.3-5.8), passage of mucus per rectum (2.2; 1.1-4.8). Anorexia was more common in the elderly patients (0.4; 0.1-0.8). This study suggests that symptomatic presentation of rectal cancer is different in the elderly but does not necessarily lead to greater delays in diagnosis nor higher rates of non-elective presentation.

The relationship between burning mouth syndrome and 48 variables was investigated in 241 patients, 45 years old and older, who had attended the Oral Medicine Clinic of the Faculty of Dentistry, University of Stellenbosch during a period of 4 years. A total of 85 cases of burning mouth syndrome were diagnosed in 65 women and 20 men. Statistically significant relationships (p < 0.05) were found with self-medication, xerostomia, and other salivary disturbances in both men and women with burning mouth syndrome when compared with their respective controls. Among the women with BMS, significant relationships were also found with anemia, inadequate diet, chronic infection, hormone therapy, ulcerative/erosive lesions, and atrophy. In contrast men with BMS showed statistically significant relationships between taking prescribed medication, central nervous system disturbances, gingivitis, and denture-related problems. In addition, significant associations were related to variables such as psychogenic factors, regurgitation, flatulence, and periodontitis.

Small bowel diverticulosis (SBD) is a rare entity. Most cases of diverticulosis are asymptomatic. SBD is often discovered incidentally during contrast studies and endoscopy. When patients report chronic gastrointestinal symptoms such as abdominal pain, bloating, flatulence, and anemia, SBD is often an overlooked diagnosis. Patients requiring treatment for SBD are those with complications such as malabsorption, hemorrhage, obstruction, and acute inflammation with abscess or rarely perforation. Malabsorption can be managed with broad-spectrum antibiotics and vitamin supplementation. Hemorrhage is treated conservatively with resuscitation efforts, but recurrent bleeding requires surgery. Enteroliths causing obstruction in the duodenum can be relieved by endoscopy, that is, by manipulation, but jejunoileal obstruction requires a resection. Pseudo- obstruction may be managed with prokinetics such as metoclopramide, erythromycin, and the 5-hydroxytryptamine 4 agonist tegaserod. Uncomplicated cases of SBD are treated with bowel rest and antibiotics. However, perforation or abscess formation not amenable to percutaneous drainage mandates surgical resection. Any patient with a triad of anemia, abdominal pain, and an abdominal radiograph with dilated loops of small bowel merits SBD in the differential diagnosis.

Celiac disease (CD) is characterized by malabsorption of nutrients in the small intestine. The availability of highly specific and sensitive serologic tests has facilitated its diagnosis, increasing the disease prevalence. The aim of this study was to determine the clinical, laboratory, and histopathological features of CD in Turkish adults. Between 1968 and 2002, CD patients presenting to the Gastroenterology Unit were evaluated retrospectively. From 2002, newly diagnosed patients were prospectively followed up. Sixty patients (39 female, 21 male) were included in the study. Mean body mass index was 22.2 +/- 5.4 kg/m2. The most common symptoms were diarrhea, weight loss, and flatulence. Most common comorbidities were anemia, osteoporosis, type 1 diabetes mellitus, and steatohepatitis. Six (10.0%) patients had a family history of diabetes mellitus; one (1.7%) patient had a family history of CD. Plasma glucose and serum gamma-glutamyltransferase levels were significantly higher in females than males. Most common histopathological findings were increased lymphocytes in the lamina propria (76.2%) and villus epithelium (59.5%). Over the years, the cumulative frequency of CD increased more in females than males. This is the first study in the literature showing the characteristics of CD in Turkish adults. In our previous recent study, the prevalence of tissue transglutaminase antibody positivity in Turkish healthy blood donors was 1.3%, indicating a high prevalence of CD in our population. In this study, the cumulative frequency of CD increased more in females than males. With the better understanding and increased suspicion of the disease, more patients are being diagnosed in our population.

Animal fascioliasis has been reported in Saudi Arabia among imported and local sheep. The paper demonstrated the parasitological and clinical features of human fascioliasis in nine out of ten male immigrant manual workers with manifestations suggesting fascioliasis. The sedimentation and Kato-Katz techniques proved effect in diagnosing Fasciola species eggs in human stool. The common clinical features were abdominal distension, flatulence, tender right-upper quadrant and easy fatigability and the least was the tinge of jaundice. Others as right upper quadrant pains, colicky abdominal pains & vomiting, epi-gastric pain and mild fever, and tympanitic abdomen were encountered. Anaemia and eosinophlia were also encountered in the ten patients. Fascioliasis patients (nine) were successfully treated with Mirazid as two capsules (600 mg) on an empty stomach an hour before breakfast for six consecutive days. Follow-up clinically and parasitologically was available in only seven fascioliasis patients who were completely cured. Follow-up for the other two fascioliasis patients was out in hand. Other parasites recovered in the stained (eosin, iodine and Zeihl-Nelson stains) smear stool samples was Entamoeba histolytica, Giardia lamblia and Cryptosporidium parvum. Besides, three were free from intestinal protozoan. The results were discussed on the light of the other work carried out regionally.

Nutritional assessment and dietary advice are fundamental to inflammatory bowel disease (IBD) patient management and all patients should have access to a dietitian. Newly diagnosed patients often think that their pre-illness diet has contributed to the development of their IBD. However, epidemiological evidence to support diet as a risk factor is lacking. How the diet contributes to the gastrointestinal microbiota is interesting, although the role is not yet clearly defined. Nutritional problems in IBD are common. Malnutrition occurs in up to 85% of patients and weight loss affects up to 80% of patients with Crohn's disease and 18-62% of patients with ulcerative colitis. Nutritional deficiencies are prevalent, particularly in relation to anaemia and osteoporosis. Intestinal strictures can be problematic in Crohn's disease and limiting fibrous foods that may cause a mechanical obstruction in the gastrointestinal tract is helpful. Patients often explore dietary exclusion to alleviate symptoms but such changes may be self-directed or inappropriately advised and can lead to further nutritional deficiencies. Some patients experience concurrent functional symptoms (e.g. abdominal bloating, abdominal pain, flatulence and diarrhoea) that can significantly affect quality of life. Recently, a group of poorly absorbed carbohydrates that occur naturally in the diet called fermentable oligo-, di-, mono-saccharides and polyols have been associated with functional symptoms by intestinal bacterial fermentation leading to rapid gas production, and an osmotic effect increasing fluid delivery to the colon. Emerging evidence indicates that a diet low in fermentable oligo-, di-, mono-saccharides and polyols can alleviate functional symptoms in IBD.

Functional and metabolic syndromes after surgery of the upper gastrointestinal tract (including the pancreas) are frequent. Resections of organs mandate the reconstruction with a change of anatomy. Predominantly, the reconstruction using a Y-en-Roux jejunal loop is used. The surgical alteration of the anatomy may lead to a different physiology. Patients after esophagectomy or gastrectomy may suffer from dysphagia, dumping syndromes, reflux and anaemia. Pancreatic resections or drainage operations may cause an exocrine or endocrine insufficiency. Patients after surgery for gastroesophageal reflux or achalasia may have gas-related symptoms such as bloating and flatulence. The treatment options of these syndromes include physical measures, drugs, interventional procedures and even revisional surgery. Detailed preoperative information of the procedure and multidisciplinary postoperative treatment (general practitioner, surgeon, gastroenterologist etc.) of evolving functional syndromes is mandatory to achieve a high standard of care.
