A novel histologic phenotype of chronic esophagitis, ie, lymphocytic esophagitis, is reported in 20 patients. Lymphocytic esophagitis is characterized by high numbers of intraepithelial lymphocytes (IELs) gathered mainly around peripapillary fields and by none (n = 12) to occasional (n = 8) CD15+ intraepithelial granulocytes. IELs expressed CD3, CD4 (42%), CD8 (36%), and granzyme B (0.2%), whereas T-cell intracytoplasmic antigen (TIA) 1 was not expressed. Of the 20 patients, 11 (55%) were 17 years or younger. Of 20 patients, 5 had no symptoms in the upper gastrointestinal tract. Only 4 (20%) of 20 patients had symptoms of gastroesophageal reflux disease and 6 (30%) of gastroduodenitis; 2 (10%) had celiac disease; 4 (20%) had carcinoma of the esophagus (1) or elsewhere (3); 1 (5%) each had hiatus hernia, gastric ulcer/asthma/blood hypertension, Hashimoto thyroiditis, and cirrhosis/diabetes; and 8 (40%) had Crohn disease. Hence, a novel histologic phenotype of chronic esophagitis called lymphocytic esophagitis is reported. Because phenotype is defined as the visible features resulting from the interaction between the genetic makeup and the environment, it is suggested that those factors might have a decisive role in the development of lymphocytic esophagitis.

Obesity is epidemic in the modern world. It is becoming increasingly clear that obesity is a major cause of cardiovascular disease, diabetes, and renal disease, as well as a host of other comorbidities. There are at present no generally effective long-term medical therapies for obesity. Surgical therapy for morbid obesity is not only effective in producing long-term weight loss but is also effective in ameliorating or resolving several of the most significant complications of obesity, including diabetes, hypertension, dyslipidemia, sleep apnea, gastroesophageal reflux disease, degenerative joint disease, venous stasis, pseudotumor cerebri, nonalcoholic steatohepatitis, urinary incontinence, fertility problems, and others. The degree of benefit and the rates of morbidity and mortality of the various surgical procedures vary according to the procedure.

Black esophagus is the uncommon endoscopic finding of extensive black discoloration of the esophageal mucosa, usually from acute esophageal necrosis. Six cases of black esophagus were seen at Mayo Clinic (Rochester, Minnesota, USA) from 1997 through 2003, and 46 cases were reported in the English-language literature from 1963 through 2003. We studied the demographics, clinical features, and outcomes of these 52 cases of black esophagus. Age and sex were known for 50 patients: the mean (SD) age was 65 years (19), and 42 patients (84%) were men. Symptoms were known for 51 patients: the most common symptom was upper gastrointestinal tract bleeding, occurring in 40 patients (78%). All 52 patients had at least one comorbid condition (with most having two or more), including duodenal ulcer in 17 (33%), cancer in 15 (29%), renal insufficiency in 15 (29%), and diabetes mellitus in 14 (28%). The suspected cause of black esophagus was reported for 40 patients: ischemia in 22 (55%); massive gastroesophageal reflux in seven (18%); and esophageal infection (Lactobacillus acidophilus, herpes simplex, Candida albicans) in four (10%). Most patients received supportive therapy, particularly acid suppression therapy. Of the 47 patients for whom outcomes were known, 17 (36%) died. There were no statistically significant differences between survivors and non-survivors. Black esophagus typically occurs in older men with at least one comorbid condition; a substantial number of patients die. Although the underlying mechanism leading to black esophagus is unknown, clinicians caring for patients with black esophagus should focus on optimizing perfusion, minimizing acid reflux, and treating esophageal infection if present.

The quality of doctor-patient communication is critical for the practice of medicine. Studies show that effective communication results in patient satisfaction and improved compliance. To better understand one aspect of this complex phenomenon we estimated the ability of people to comprehend 11 commonly used medical terms. We used multiple choice questions in a telephone survey of 1167 Icelanders aged 16-75 years. Results (% of participants with correct answers): Gastroesophageal reflux (72), emphysema (25), steroids (40), one tablet twice a day (79), side effects (67), bronchitis (68), white blood cells (56), erythrocyte sedimentation rate (33), diabetes mellitus (72), antibiotics (87), chronic obstructive pulmonary disease (42). Variables associated with better comprehension were: Female gender (better in 7/10 questions), university degree (10/10) and high income (9/10). Decision tree analysis showed that education had the most impact. The youngest participants (age 16-24) had the worst outcome in seven out of 10 questions. The results define certain medical terms that require more careful explanation than others. They also indicate that those of young age, low socioeconomic status and less educated require more help in understanding medical terms. Interestingly, 21% of participants failed to understand a very simple medication order, emphasizing the importance of explaining these in detail. The data may also have implications for informed consent. A larger study exploring the public comprehension of multiple medical terms should be considered.

Morbidly obese patients undergoing bariatric surgery commonly have multiple obesity-related comorbidities, including hypertension (HTN), diabetes mellitus (DM), hyperlipidemia (HLP), and gastroesophageal reflux (GERD). Medical management of these conditions can be costly. The aim of this study was to determine changes in the monthly prescription medication costs in morbidly obese patients who underwent laparoscopic gastric bypass. We examined the data on 77 morbidly obese patients receiving medications prescribed for GERD, DM, HTN, and/or HLP before and after laparoscopic gastric bypass. Changes in medication usage were recorded at 3-month intervals. The retail cost for these medications was obtained from drugstore.com. There were 55 women with a mean age of 45 +/- 11 years. The mean body mass index was 47 +/- 6. The mean excess body weight loss was 67 +/- 14 per cent at 1 year. The mean number of prescription medication per patient was reduced from 2.4 preoperatively to 0.2 at 12 months after surgery. The mean monthly medication cost decreased from dollars 196 preoperatively to dollars 54 one month after surgery, representing a 72 per cent cost savings. One month postoperatively, medication cost saving for GERD was 81 per cent; for DM was 69 per cent; for HLP was 53 per cent; and for HTN was 43 per cent. The mean monthly medication cost savings for the first year after surgery was dollars 168, with a yearly savings of dollars 2016 per patient. Improvement of GERD, DM, HLP, and HTN occur as early as 1 month after laparoscopic gastric bypass results in substantial monthly medication cost savings.

This chapter is complementary to the others in this volume focusing on preoperative fasting routines. In it we discuss some of the issues in need of more research to define best practice. One of these is the role of fasting in emergency patients. Modern preoperative fasting recommendations almost exclusively deal with elective patients. In emergency patients preoperative fasting cannot secure gastric emptying to reduce the risk of pulmonary aspiration. Hence, surgery should be timed according to the urgency of the situation, and the patient should always be treated as if the stomach was full. More data are needed to better define what is going on in the gastrointestinal tract during the perioperative period in these patients. In certain patient groups--such as patients with diabetes, gastro-oesophageal reflux disease and/or obesity--the data are insufficient to give complete guidance to best practice. Preoperative fasting guidelines also affect fluid balance and perioperative fluid management, a topic of debate in recent years. In addition, carbohydrate-enriched fluids for oral use in the preoperative phase have been shown to have a positive effect on postoperative metabolism. Recent studies also suggest that the immune system would be less affected by surgery with such preparations. Last but not least, new scientific evidence alone is not enough to change daily practice. Active implementation of new evidence is also needed. To improve perioperative care, anaesthesiologists, surgeons and the nursing staff must work together.

Evidence is mounting that obstructive sleep apnea causes or contributes to many chronic medical diseases, and that treatment with continuous positive airway pressure (CPAP) often improves concomitant diseases. The author reviews the association of obstructive sleep apnea with arterial hypertension, pulmonary hypertension, stroke, coronary artery disease, heart failure, sudden death, gastroesophageal reflux disease, and diabetes mellitus.

Sarcoidosis disease expression differs along racial/ethnic lines and black race has been cited as a poor prognostic factor. Besides genetic, healthcare, and socioeconomic factors, comorbid illnesses may influence sarcoidosis disease expression. We set out to investigate the association between comorbid illnesses and chest radiographic severity in a population of African-American sarcoidosis patients. The study was designed as a retrospective database analysis. The hospital and outpatient databases of the Grady Health System were searched to capture adult patients between November 1999 and December 2003 with the ICD-9 codes of 135 or 519.8, along with all associated secondary and tertiary diagnostic codes. Patient electronic pathology and radiographic reports were reviewed for tissue biopsies showing noncaseating granulomas and for chest radiographic Scadding stage. A total of 165 African-American patients were identified (64% female, 43 +/- 10 years old). Ninety percent (149/165) had comorbid illnesses. The most frequent chronic comorbid illnesses were hypertension (39%), diabetes mellitus (19%), anemia (19%), asthma (15%), gastroesophageal reflux disease (15%), depression (13%), and heart failure (10%). Females had increased frequency and clustering of chronic illnesses. Chest radiographic stages were more severe in patients with anemia, depression, and those less than 40 years old. Males, within each chronic illnesses category, had more severe CXR stages compared to females; however, significance was not achieved. We concluded that most adult patients with sarcoidosis have comorbid illnesses and these, in addition to gender differences, may influence sarcoidosis disease expression. Screening for comorbid illnesses should be an important aspect of sarcoidosis patient management.

Esophageal dysfunctions occur frequently in patients with diabetic neuropathy, and the complication of gastroesophageal reflux disease(GERD) has also been reported. However, the characteristics of GERD complicated with diabetes mellitus are obscure because no detailed assessment was performed. We performed long-term ambulatory esophageal pH and motility monitoring in diabetic patients, and analyzed the data in detail. Esophageal dysfunctions including GERD were significantly related to diabetic neuropathy and duration. Although GERD was frequently complicated with diabetes mellitus, the symptoms were not apparent in diabetic patients. The average score of a questionnaire was extremely low, and no significant difference in score was observed between patients with and without gastroesophageal reflux. We should keep in mind that diabetic patients have the abnormal gastroesophageal reflux even when they do not complain of the related symptoms.
