Acute adrenal insufficiency postoperatively is an uncommon problem and, if unrecognized, it may cause serious morbidity and can be fatal. It can occur as the result of acute bilateral adrenal hemorrhage associated with anticoagulation, inadvertent injury to or removal of a solitary adrenal gland, or postoperative stress in an individual with incipient adrenal insufficiency. Its manifestations, such as fever, tachycardia, hypotension, lethargy, abdominal pain and gastrointestinal dysfunction, mimic the other more common postoperative complications and compound the difficulty in establishing the correct diagnosis. Once the diagnosis is made the condition is readily managed successfully. We report 3 cases of acute adrenal insufficiency occurring after salvage cystectomy, ileal replacement of the ureter and retropubic prostatectomy, which illustrate the salient clinical features, problems in diagnosis and predisposing risk factors. All 3 patients survived once the diagnosis of adrenal insufficiency was made. These cases emphasize the need to be aware of the possibility of this complication to make the correct diagnosis and to institute proper treatment.

Because it may be difficult to evaluate gastrointestinal diseases in children with insulin-dependent diabetes mellitus (IDDM), this report highlights several clinical features unique to diabetes and emphasizes the relationship between gastrointestinal pathology and glycemic control. Two children with IDDM are described whose hyperglycemia, ketosis, and abdominal pain were the presenting features of H. pylori-positive duodenal ulcer disease and acute appendicitis, respectively. A third nondiabetic child developed persistent postprandial hyperglycemia as the initial manifestation of dumping syndrome. These patients illustrate the relationship between glycemic control and gastrointestinal pathology in children with diabetes and the effects of gastrointestinal dysfunction on glucose regulation in nondiabetic children. In children with IDDM, gastrointestinal pathology can be confused with ketoacidosis and complicate diabetes control and management. Early recognition and treatment of the underlying gastrointestinal disease often improves glycemic control. Furthermore, severe gastrointestinal dysfunction in nondiabetic children may deleteriously influence glycemic regulation and may be confused with childhood diabetes.

The gastrointestinal problems in cystic fibrosis (CF) may limit energy and nutrient availability and also cause symptoms such as abdominal pain and disturbed bowel habit which may further suppress appetite or alter the diet. Taken together this may lead to an inadequate supply of energy and nutrients to meet the nutritional requirements of the individual resulting in restricted growth or weight loss. A failure to optimize the digestive and absorptive capacity of the gastrointestinal tract places greater emphasis upon nutritional management by food intake alone. Practitioners need to focus more on gastrointestinal dysfunction in CF and its impact upon food intake in order to improve the efficacy of nutritional management. Refined stable isotopic tracers allow further exploration of the pathophysiology of the gastrointestinal tract in terms of nutrient availability. In clinical practice, a closer assessment of gastrointestinal function is supported by the use of simple, noninvasive tools which, both objectively and systematically, characterize those patients who have problems.

Scrub typhus is an acute febrile illness caused by Orientia induced vasculitis, which is common in Asia and the Pacific Islands and is sometimes also encountered in Western countries. Even though it can cause multi-organ dysfunctions, there is limited information regarding the relationship between scrub typhus infection and gastrointestinal dysfunction. Therefore, a cross-sectional study was conducted to discover the gastrointestinal manifestations of septic patients with scrub typhus infection. During the study period, 80 septic cases were recruited, and according to the results of immunofluorescent antibody testing (IFA), 20 (25%) were found to have scrub typhus infection. The most common gastrointestinal symptoms of scrub typhus patients were vomiting 13 (65%), nausea 12 (60%), diarrhea 9 (45%), and hametamesis or melena 5 (25%). Gastrointestinal signs included hepatomegaly 8 (40%), jaundice 7 (35%), and abdominal pain 4 (20%). Elevation of SGOT, SGPT, and alkaline phosphatase were 16 (80%), 14 (70%), and 16 (80%), respectively. Direct bilirubin was elevated in 19 (95%) of the cases and half of the cases had a low serum protein level. Of scrub typhus cases, 8 (40%) had eschars. The sites of eschars were mostly in hidden areas, such as on the back, genitalia and abdomen. Three of the five patients with eschar had hepatomegaly on ultrasound examination. The significant findings of the scrub typhus septic patients with eschar on endoscopic examination were gastritis in two cases, gastritis with gastric erosion in two cases, and one case showed a duodenal ulcer and erosion. The differentiating point for endoscopic findings in scrub typhus compared to the other causes was that the stomach lesions were more frequent and severe than the duodenal lesions. According to our endoscopic findings, physicians should be aware of gastric and duodenal lesions in febrile patients with gastrointestinal symptoms, such as abdominal pain or discomfort and indigestion. Scrub typhus can cause gastrointestinal and liver dysfunction.

Women often complain gut symptoms during pregnancy and the luteal phase of the menstrual cycle. To investigate the relationship between ovarian steroids and the abnormal gut motility and sensitivity, the expressions of cholecystokinin (CCK), calcitonin gene-related peptide (CGRP) and their receptors in stomach were studied in ovariectomized rats. Blood samples were collected for estradiol (E(2)), progesterone (P(4)), CCK and CGRP radioimmunoassay. Expression of CCK(A) receptor in fundus was assessed by Western blot and CGRP receptor was determined by (125)I-CGRP radioligand binding assay (RBA). The replacement therapy with estradiol benzoate (EB) could dose-dependently increase the plasma CCK level and the expression of gastric CCK(A) receptor (P<0.05 respectively). P(4) replacement therapy could stimulate the release of CGRP and increase the binding sites of CGRP receptors in stomach (P<0.05 respectively). The combined effect of EB and P(4) was to stimulate the release of CCK and CGRP, and to increase the expressions of gastric CCK(A) and CGRP receptors. These results indicate that EB could inhibit gastric emptying by increasing CCK secretion and CCK(A) receptor expression in ovariectomized rats. P(4) could increase gut sensitivity by up-regulating the release of CGRP and the activity of CGRP receptor. It could be deduced from these observations that CCK(A) and CGRP receptor antagonists could be used for female patients who suffer from gastrointestinal dysfunction closely related with the menstrual cycle, such as distension, satiety, bloating and abdominal pain.

To determine if there is a role for routine abdominal imaging in predicting postoperative intraabdominal abscess after appendectomy for the pediatric ruptured appendix. From January 2000 to December 2003 inclusive, 44 consecutive pediatric patients with a ruptured appendix had an open appendectomy and were treated for a minimum of 5 days with triple antibiotics. On postoperative day 5, each patient was evaluated for symptoms (fever, abdominal pain, gastrointestinal dysfunction) and radiological evidence of an intraabdominal fluid collection. Further treatment was determined by the clinical evidence of continuing infection. On postoperative day 5, 36 (82%) of the 44 patients were asymptomatic, had an intraabdominal fluid collection less than 5 cm, diagnosed by ultrasound or computed tomography and received no further treatment. Two of these 36 patients (6%) returned within a week, symptomatic and with a larger collection suspicious for an intraabdominal abscess and requiring further treatment. The other 8 (18%) were symptomatic, and had an intraabdominal abscess more than 5 cm on imaging. All required further treatment, and recovered well. The use of routine abdominal imaging on postoperative day 5, (compared with clinical evaluation), did not improve the ability to predict the development of an intraabdominal abscess.

Follow-up of the large numbers of patients undergoing bariatric surgery poses problems for surgical programs and for internists who care for morbidly obese patients. Early surgical follow up is concentrated on the perioperative period to ensure healing and care for any surgical complications. It is especially important to treat persistent vomiting to avoid thiamine deficiency. Subsequently, monitoring weight loss and resolution of comorbidities assumes more importance. Identification and management of nutritional deficiencies and other unwanted consequences of surgery may become the responsibility of internists if the patient no longer attends the office of the operating surgeon. The long-term goal is to avoid weight regain and deficiencies, especially of protein, iron and vitamin B12, and calcium and vitamin D. Abdominal pain and gastrointestinal dysfunction should be investigated promptly to exclude or confirm such conditions as small bowel obstruction or gallstones. Good communication between bariatric surgeons and internal medicine specialists is essential for early and accurate identification of problems arising from bariatric surgery.

Numerous surveys of athletes reveal high rates of exertional abdominal pain and gastrointestinal dysfunction. These complaints often are thought to be self-limiting and benign, and they may be mediated by physiological changes that take place in the gastrointestinal tract. However, when these complaints interfere with an athlete's training or competition, it is important to evaluate for underlying pathology. The goal of this article will be to briefly describe the relevant exercise-associated changes of the gastrointestinal tract and provide a differential diagnosis and a proposed mechanism of evaluation of exertional abdominal pain. The etiologies most frequently written about include exercise-associated transient abdominal pain (ETAP or stitch), reflux, diarrhea, ischemia, and musculoskeletal pain. Less common etiologies include cardiorespiratory disease, and rare occurrences of hypoferritinemia, congenital supernumerary ligaments of the gallbladder, cholangitis, and pancreatitis have been published as case reports.

Many children with autism spectrum disorders (ASDs) suffer from gastrointestinal problems such as diarrhoea, constipation and abdominal pain. This has stimulated investigations into possible abnormalities of intestinal microbiota in autistic patients. Therefore, we designed this study to identify differences (and/or similarities) in the microbiota of children with autism (without gastrointestinal dysfunction: n = 23; with gastrointestinal dysfunction: n = 28) and their neurotypical siblings (n = 53) who share a similar environment using bacterial tag-encoded FLX amplicon pyrosequencing. Regardless of the diagnosis and sociodemographic characteristics, overall, Firmicutes (70%), Bacteroidetes (20%) and Proteobacteria (4%) were the most dominant phyla in samples. Results did not indicate clinically meaningful differences between groups. The data do not support the hypothesis that the gastrointestinal microbiota of children with ASD plays a role in the symptomatology of ASD. Other explanations for the gastrointestinal dysfunction in this population should be considered including elevated anxiety and self-restricted diets.

Eosinophilic gastrointestinal disorders are chronic inflammatory diseases in which eosinophils highly infiltrate into gastrointestinal tissue, resulting in gastrointestinal dysfunction. Here, we report a case of pediatric eosinophilic gastroenteritis (EGE). A 7-year-old boy with multiple food allergies (cow milk, hen's egg, fish,shellfish, and chicken) was admitted to our hospital because of continuous abdominal pain and vomiting. His soy allergy had been diagnosed to have oral tolerance based on an oral food challenge at the age of 6 years. He was diagnosed with EGE based on biopsy findings showing eosinophilic infiltration ( 20 eosinophils per high-power field) into the gastrointestinal mucosa. A diet eliminating soy, wheat, beef, pork, rice, and sesame in addition to the food that had already been eliminated and oral corticosteroids improved his symptoms and peripheral eosinophilia. A relapse of both abdominal pain and peripheral eosinophilia after the reintroduction of soy or pork identified them as foods causative of EGE. This report highlights the utility of elimination diets in improving EGE symptoms and the subsequent reintroduction of offending foods in identifying causative foods. Furthermore,EGE onset should be considered when introducing potentially allergic food in the management of food allergy. J. Med. Invest. 66 : 201-204, February, 2019.
