The application of novel techniques to quantify gastric motor function and gastric emptying has yielded important insights into the prevalence, pathogenesis and clinical sequelae of gastroparesis. Both acute and chronic gastroparesis occur frequently; gastric emptying of solids is delayed in 30% to 50% of patients with diabetes mellitus, functional dyspepsia and gastroesophageal reflux disease. While many patients with gastroparesis experience upper gastrointestinal symptoms that adversely affect quality of life, the concept that symptoms are inevitably the direct outcome of delay in gastric emptying is now recognized to be overly simplistic. In contrast, the potential impact of gastroparesis on oral drug absorption and blood glucose control in patients with diabetes mellitus has probably been underestimated. While the use of prokinetic drugs (cisapride, domperidone, metoclopramide and erythromycin) forms the mainstay of therapy in symptomatic patients with gastroparesis, a number of novel pharmacological therapies are being evaluated, and preliminary studies using gastric pacing show promise.

This review illustrates, through a series of case histories, how oral medicine insights aid the diagnosis and management of patients with excessive tooth wear. The cases reviewed are drawn from the records of 500 southeast Queensland patients referred to the author over a 12 year period. Patients most at risk of dental erosion have work and sports dehydration, caffeine addiction, gastro-oesophageal reflux, asthma, diabetes mellitus, hypertension or other systemic diseases or syndromes that predispose to xerostomia. Saliva protects the teeth from the extrinsic and intrinsic acids which cause dental erosion. Erosion, exacerbated by attrition and abrasion, is the main cause of tooth wear. These cases illustrate that teeth, oral mucosa, salivary glands, skin and eyes should be examined for evidence of salivary hypofunction and attendant medical conditions. Based on comprehensive oral medicine, dietary analyses and advice, it would seem patients need self-management plans to deal with incipient chronic tooth wear. The alternative is the expensive treatment of pain, occlusal damage and pulp death required to repair the effects of acute severe tooth wear.

There are few long-term follow-up reports of the Angelchik prosthesis (AP). We report the longest follow-up series (66-192 months, average 145 months) to date. Between October 1983 and January 1994, 65 patients (45 men and 20 women) aged between 29 and 84 years (mean 52 years) had an AP inserted for gastro-oesophageal reflux (GOR) with or without hiatus hernia (HH). Clinical, radiological, endoscopy, and operative details were reviewed. Postoperative complications, investigations, and follow-up details were critically analyzed. All living patients (n = 53) with an AP in situ were interviewed and symptomatic assessment was carried out using a modified Visick system (I-IV). The average duration of the GOR symptoms before the operation was 5.7 years (range 10 months to 20 years). The average hospital stay was 8 days (range 5-15 days). Postoperatively, five patients developed chest infection/atelectasis, four had superficial wound infection, two had deep vein thrombosis (one with pulmonary embolism), one had urinary retention, and four developed an incisional hernia. Six patients (three with an AP in situ) died of other medical conditions. Ten (15%) patients had removal of the prosthesis. Eight (12%) and 11 (17%) had transient and persistent dysphagia, respectively. Thirteen (20%) and five (8%) patients had distal slippage and proximal migration of the prosthesis, respectively. One patient had erosion of the AP into the stomach, while in another patient, the straps of the prosthesis ruptured. Of the 53 living patients with an AP in situ, 28 (53%) were Visick I, 11 (20%) were Visick II, 11 (20%) were Visick III, and 3 (7%) were Visick IV. We conclude that the AP has poor long-term results, with only 66% attaining Visick I and II, and a prosthesis removal rate of 15% (10/65). Patients with preoperative dysphagia, hypothyroidism, and diabetes tend to do worse with an AP. Obese patients and those with failed previous fundoplication seemed to fare well with an AP. In view of poor long-term results and high incidence of complications as compared to other conventional operations for GOR, we cannot recommend the continued use of the AP.

Previous studies showed that either the urease activity possessed by H. pylori and the bacterial load may influence the results of the [13C] urea breath test. However, the correlation between urease activity and dyspepsia is unclear. The aim of our study was to evaluate whether the urease activity of the gastroduodenal tract may influence the severity of dyspeptic symptoms. In all, 2520 dyspeptic patients (1109 men, 1411 women; mean age 47 +/- 16 years) without gastroesophageal reflux disease, diabetes, vascular disorders, liver and biliary tract diseases, and tumors of the gastrointestinal tract and with a normal appearing abdominal ultrasonography were enrolled. All these patients underwent a [13C] urea breath test and filled out a questionnaire on dyspeptic symptoms. Subjects were divided in five different groups according to delta over baseline (DOB) values (group 1 < 3.5, group 2 = 3.5-6; group 3 = 6.1-11, group 4 = 11.1-23, group 5 > 23.1). The prevalence and intensity of dyspeptic symptoms were compared among groups. In all, 1688 patients (67%, 928 females and 760 males; mean age 48 +/- 15 years) were H. pylori-positive. The chi-squared test and analysis of variance showed increase of frequency and intensity of each dyspeptic symptom according to DOB values. In conclusion, Dyspepsia may parallel gastric urease activity. However, whether higher DOB values are related to higher bacterial load or, alternatively, to the presence of particular H. pylori strains able to produce larger amounts of urease is uncertain.

Sarcoidosis remains a fascinating illness that almost always affects the respiratory tract but often involves many other organs as well. Although many patients seem to have only an intrathoracic illness, with perhaps one other site or organ involved, others can experience a severe multi-organ disease. The inciting stimulus, even if unknown, can elicit an immunologic host response-the non-caseating granuloma-in almost every organ. It is intriguing that this stimulus can be so widespread throughout the body, while the biology of the disease can be so variable. Many series of patients with sarcoidosis have reported the multiple organs involved and the clinical presentation. Our series of 67 patients (40 female, 27 male, mean age 38.7 years +/- 13.2 (SD) at time of diagnosis) generally mirrors the clinical pattern found in five comparison series that span the past 60 years. However, more emphasis is given in this series to associated medical conditions that can complicate the presentation of sarcoidosis, as well as to co-morbid illnesses that must be managed in addition to the patient's sarcoidosis. Although most patients had intrathoracic sarcoidosis diagnosed at initial evaluation (40%), many had other organs or bodily sites involved in addition (or subsequently) as the illness evolved. Confounding the initial patient evaluation were two factors: (1) the presence of an occupational respiratory exposure(s) (n = 25 or 37% of patients); (2) a previously diagnosed malignancy (n = 6 or 9%) that heightened the possibility of a primary malignancy presenting in the chest, or the reactivation of a prior malignancy (breast, thyroid, and lymphoma) that could metastasize to the lung. Symptoms present when a patient's diagnosis was established usually differentiated respiratory and/or abdominal organ involvement. Although respiratory symptoms could be absent (n = 18 or 27%) for many patients with incidental thoracic findings, most had typical ones, including exertional dyspnea. For patients with an abdominal presenting illness (n = 11 or 16%), nonspecific digestive and abdominal symptoms were experienced as well as arthralgias. Almost every patient had at least one important other illness that factored significantly into the management of their sarcoidosis. Older patients had more illnesses, such as cardiovascular illness, diabetes mellitus, neurologic problems, and functional gastrointestinal symptoms. Depression affected all ages and was probably underrecognized; more emphasis on this illness is needed. Obesity was associated with disordered sleep syndromes, but not invariably so, as half the subjects had a good body habitus. Thus, many of the other illnesses experienced by sarcoidosis patients are common problems that middle-aged people develop. However, digestive and gastroenterological symptoms seemed disproportionately frequent in this series. This is a component of multi-organ sarcoidosis that has not received extensive coverage in the literature. Approximately one-third of sarcoidosis patients had one of two very common problems-gastroesophageal reflux or irritable bowel syndrome. But these are common problems, and it is thus necessary to separate these symptoms from those associated with abdominal visceral involvement of sarcoidosis. Although liver and/or splenic involvement with sarcoidosis do not cause organ dysfunction or insufficiency, they can contribute to abdominal symptoms. Finally, it remains of interest whether inflammatory bowel disease-Crohn's disease in particular-is another organ manifestation of sarcoidosis, or is it unrelated?

Numerous considerations affect the diagnosis and management of overactive bladder (OAB) in older patients, including neurologic and cardiovascular disorders, musculoskeletal conditions, diabetes, and psychiatric disorders. Older patients are commonly prescribed multiple medications, and many medications can contribute to OAB symptoms and/or interact with drug treatment for OAB. In addition to chronic illnesses and related medications, several factors outside the lower urinary tract can play an important part in managing OAB in older patients. These factors include mobility disorders, cognitive impairment, bowel habits, and fluid intake. Moreover, OAB often does not occur in isolation in the geriatric population. Estrogen deficiency and sphincter weakness in women, prostatic enlargement and obstruction in men, and impaired bladder contractility in both sexes are common and can have prominent effects on management. The diagnostic evaluation of geriatric patients with OAB can usually be accomplished with a basic assessment, without more invasive and expensive procedures. Treatment depends on numerous factors, ranging from comorbidities and functional status to transportation, finances, and patient and caregiver preferences. Adverse effects of bladder-relaxant medications can be bothersome and exacerbate existing conditions common in older patients (eg, constipation, glaucoma, gastroesophageal reflux, and dementia). Setting realistic goals for treatment and communicating them clearly to older patients and their caregivers are crucial for patient satisfaction. There are myriad opportunities for research designed to improve the management of OAB in the geriatric population.

Diabetes mellitus and cystic fibrosis (CF) have been reported before in the literature, but they have never been reported in the same patient in the Middle East. We present the first reported case of insulin dependent diabetes mellitus (IDDM) and CF in 2 siblings of the same family. Both siblings were diagnosed early in life with IDDM, and their diabetes was well controlled on insulin. Cystic fibrosis was diagnosed in the first case one year after IDDM was diagnosed due to history of chronic cough and in the 2nd case by family screening. Both had severe failure to thrive, recurrent chest infections and gastro-esophageal reflux. With treatment both showed clinical improvement, but continued to have moderate lung disease radiologically and by pulmonary function test.

The prevalence of obesity is increasing worldwide. In the United States, in 1999, 27% of adults had a body mass index >30 kg/m(2), almost double the prevalence of 20 years earlier. The estimated mortality from obesity-related diseases in the United States is approximately 300,000 annually and growing. In the future, mortality related to obesity is expected to exceed that of smoking. Numerous diseases are caused or made worse by obesity. These include type 2 diabetes; hypertension; dyslipidemia; ischemic heart disease; stroke; obstructive sleep apnea; asthma; nonalcoholic steatohepatitis; gastroesophageal reflux disease; degenerative joint disease of the back, hips, knees, and feet; infertility and polycystic ovary syndrome; various malignancies; and depression. Type 2 diabetes is perhaps the most visible obesity-related problem. Present in at least 14 million Americans, it leads to serious complications and premature death. It is largely caused by obesity, and is generally cured by weight loss. The quality of life of the obese is markedly reduced, and the costs to health care systems are great. Preventive programs have yet to affect the rising prevalence. An effective solution is needed.

An obese 76-year-old woman with type II diabetes, hypertension, coronary artery disease, and gastroesophageal reflux was found to have a 6-cm lower-pole mass in a solitary functional right kidney. Because her religious beliefs prohibited blood transfusion, minimally invasive surgery--a laparoscopic partial nephrectomy--was performed, with a good result. Minimally invasive surgery, perhaps with administration of erythropoietin, iron-dextran, or both, is often a good option for severely anemic patients or those whose religious beliefs are opposed to transfusion. Methods of minimizing blood loss intraoperatively are reviewed.

Acute changes in blood glucose concentration have major effects on gastrointestinal motor function. Patients with diabetes mellitus have an increased prevalence of gastroesophageal reflux. Transient lower esophageal sphincter (LES) relaxation (TLESR) is the most common sphincter mechanism underlying reflux. The aim of this study was to investigate the effect of acute hyperglycemia on triggering TLESRs evoked by gastric distension in healthy volunteers. TLESRs were stimulated by pressure-controlled and volume-controlled (500 ml) gastric distension using an electronic barostat and performed on separate days. On each day, esophageal manometry was performed in the sitting position during gastric distension for 1 h under euglycemia (5 mM), and either marked hyperglycemia (15 mM) or physiological hyperglycemia (8 mM) in randomized order was maintained by a glucose clamp. Marked hyperglycemia doubled the rate of TLESRs in response to both pressure-controlled [5 (3-10.5, median or interquartile range) to 10 (9.5-14.5) per hour, P < 0.02] and volume-controlled [4 (2.5-7.5) to 10.5 (7-12.5) per hour, P < 0.02] gastric distension but had no effect on basal LES pressure. Physiological hyperglycemia had no effect on the triggering of TLESRs or basal LES pressure. In healthy human subjects, marked hyperglycemia increases the rate of TLESRs. Increase in the rate of TLESRs is independent of proximal gastric wall tension. Mechanisms underlying the effect remain to be determined. Hyperglycemia may be an important factor contributing to the increased esophageal acid exposure in patients with diabetes mellitus.
