The observation of the Side-effects and influent factores after 75g OGTT indioated that the aotal rate of side-effects was 52.43%. After OGTT the commonest side-effect was vomiting. Others were dizzy and palpitation. The side-effects were also related to age, sex, starvation, speed of taking glucose water, water volum of dissolving glucose, gastrointestinal diseases, blood glucose level, etc. It was recommended in this paper that the speed of taking glucose water should be 3-5 minutes, the water temperature below 40 degrees C and starvation about 14 hours.

Alcoholic ketoacidosis (AKA) is an important and probably underdiagnosed differential diagnosis for metabolic acidosis with an increased anion gap. It occurs in patients with prolonged ethanol intake. After a brief period of starvation induced by alcoholic gastritis patients typically present with vomiting, abdominal pain and Kussmaul breathing. Routine testing for urine or serum ketones with ketostix may be negative, since they do not detect beta-hydroxybutyrate and this is characteristically elevated in AKA. We present three cases of AKA and discuss diagnosis, pathophysiology and management of this disorder.

Anorexia nervosa (AN) and bulimia nervosa (BN) are potentially fatal eating disorders which primarily affect adolescent females. Differentiating eating disorders from primary gastrointestinal (GI) disease may be difficult. GI disorders are common in eating disorder patients, symptomatic complaints being seen in over half. Moreover, many GI diseases sometimes resemble eating disorders. Inflammatory bowel disease, acid peptic diseases, and intestinal motility disorders such as achalasia may mimic eating disorders. However, it is usually possible to distinguish these by applying the diagnostic criteria for eating disorders and by obtaining common biochemical tests. The primary features of AN are profound weight loss due to self starvation and body image distortion; BN is characterized by binge eating and self purging of ingested food by vomiting or laxative abuse. GI complications in eating disorders are common. Recurrent emesis in BN is associated with dental abnormalities, parotid enlargement, and electrolyte disturbances including metabolic alkalosis. Hyperamylasemia of salivary origin is regularly seen, but may lead do an erroneous diagnosis of pancreatitis. Despite the weight loss often seen in eating disorders, serum albumin, cholesterol, and carotene are usually normal. However, serum levels of trace metals such as zinc and copper often are depressed, and hypophosphatemia can occur during refeeding. Patients with eating disorders frequently have gastric emptying abnormalities, causing bloating, postprandial fullness, and vomiting. This usually improves with refeeding, but sometimes treatment with pro-motility agents such as metoclopromide is necessary. Knowledge of the GI manifestations of eating disorders, and a high index of suspicion for one condition masquerading as the other, are required for the correct diagnosis and management of these patients.

1. A chronic alcoholic with severe metabolic acidosis presents a difficult diagnostic problem. The most common cause is alcoholic ketoacidosis, a syndrome with a typical history but often misleading laboratory findings. This paper will focus on this important and probably underdiagnosed syndrome. 2. The disorder occurs in alcoholics who have had a heavy drinking-bout culminating in severe vomiting, with resulting dehydration, starvation, and then a beta-hydroxybutyrate dominated ketoacidosis. 3. Awareness of this syndrome, thorough history-taking, physical examination and routine laboratory analyses will usually lead to a correct diagnosis. 4. The treatment is simply replacement of fluid, glucose, electrolytes and thiamine. Insulin or alkali should be avoided. 5. The most important differential diagnoses are diabetic ketoacidosis, lactic acidosis and salicylate, methanol or ethylene glycol poisoning, conditions which require quite different treatment. 6. The diagnostic management of unclear cases should always include toxicological tests, urine microscopy for calcium oxalate crystals and calculation of the serum anion and osmolal gaps. 7. It is suggested here, however, that the value of the osmolal gap should be considered against a higher reference limit than has previously been recommended. An osmolal gap above 25 mosm/kg, in a patient with an increased anion gap acidosis, is a strong indicator of methanol or ethylene glycol intoxication.

Hepatic lipidosis occurs when lipid mobilized to the liver exceeds lipid leaving the liver via formation of very-low-density lipoproteins or by oxidation. Hepatic lipidosis in cats is associated with overt liver dysfunction. In affected cats, excess lipid is mobilized to the liver because of starvation. Removal of hepatic lipid may be impaired because of protein malnutrition, a relative carnitine deficiency, or oxidative damage to peroxisomes and other hepatic organelles. Hepatic lipidosis occurs in adult cats, and is manifest by signs of weight loss, depression, vomiting, and icterus. Diagnosis is achieved by evaluating laboratory and diagnostic imaging data, in conjunction with a liver biopsy. Aggressive tube feeding is the treatment of choice. With this treatment, survival rates are 60% to 80%.

The reproductive and sexual histories of women who had recovered or were recovering from bulimia nervosa were examined. Of 48 consecutive female patients, 43 were studied 10-15 years after first presenting for treatment. At follow-up, 74% were considered recovered and 26% still had an eating disorder. Only 2 women fulfilled the criteria for bulimia nervosa. A history of amenorrhea was common (81% of women), 63% of women being without their menstrual periods for more than 12 months. Menstruation was present in women at a body mass index of 19 or more who were no longer using the weight loss practices of self-induced vomiting, laxative abuse, and starvation. Bulimia nervosa women are more likely to be investigated for infertility when their eating disorder is active. Bulimia sufferers are sexually active, but have times of withdrawing from their partners and ceasing sexual behavior. They associate their sexual feeling with body weight, pregnancy, breastfeeding, and status of their relationships. Marital breakdown is also more common but only if the eating disorder was active at the time of marriage. Forty-five percent left their relationship had a negative effect on their eating disorder. Short-term episodes of bulimic-free behavior are associated with pregnancy and breastfeeding in some pregnancies. Termination of pregnancy occurs more often. The prevalence of miscarriage, hyperemesis gravidarum, and postnatal depression was greater among women who had not recovered from their eating disorder at the time of their pregnancy. Recovery from eating disorder behavior before attempting conception reduces the prevalence of the gynecologic, obstetric, and psychiatric problems associated with eating disorder behavior.

Gastric reduction operations are designed to control body weight by establishing a small, meal-size juxtaesophageal, gastric pouch that empties into the jejunum (gastric bypass) or the larger portion of the stomach (gastroplasty). If the outlet of the pouch is too small, a patient may be limited to ingesting clear liquids. Vomiting then occurs if heavier liquids or normal foods are taken. An occasional patient has difficulty eating properly and vomits even though the pouch volume and outlet are of optimum size. For a patient who reports vomiting, a distinction must be made between episodic improper eating and uncontrolled starvation. Three types of starvation injury are described: (1) sudden death from protein malnutrition; (2) refeeding syndrome; and (3) Wernicke-Korsakoff syndrome. The mechanisms of the development, manifestations, prevention, and treatment of these complications are explained. Surgeons who treat severe obesity should be aware of these complications and be prepared to manage patients who have uncontrolled vomiting so that such complications either do not develop or are recognized and treated as early as possible before serious and irreversible injury occurs.

Porphyrias are inherited defects of heme synthesis with manifestations that can mimic surgical diseases; they can be provoked by administration of certain drugs. Manifestations such as abdominal pain, vomiting, tachycardia, hypertension, neuropathy, fever, confusion, and seizures have been described. Management of patients with porphyria is designed to avoid triggering drugs, such as barbiturates, and perhaps, benzodiazepines and ketamines. Nontriggering drugs should be used in the management of patients with porphyria. Because starvation can induce an attack, glucose infusions are important in the prevention and treatment of porphyria.

The cachexia-anorexia syndrome occurs in chronic pathophysiologic processes including cancer, infection with human immunodeficiency virus, bacterial and parasitic diseases, inflammatory bowel disease, liver disease, obstructive pulmonary disease, cardiovascular disease, and rheumatoid arthritis. Cachexia makes an organism susceptible to secondary pathologies and can result in death. Cachexia-anorexia may result from pain, depression or anxiety, hypogeusia and hyposmia, taste and food aversions, chronic nausea, vomiting, early satiety, malfunction of the gastrointestinal system (delayed digestion, malabsorption, gastric stasis and associated delayed emptying, and/or atrophic changes of the mucosa), metabolic shifts, cytokine action, production of substances by tumor cells, and/or iatrogenic causes such as chemotherapy and radiotherapy. The cachexia-anorexia syndrome also involves metabolic and immune changes (mediated by either the pathophysiologic process, i.e., tumor, or host-derived chemical factors, e.g., peptides, neurotransmitters, cytokines, and lipid-mobilizing factors) and is associated with hypertriacylglycerolemia, lipolysis, and acceleration of protein turnover. These changes result in the loss of fat mass and body protein. Increased resting energy expenditure in weight-losing cachectic patients can occur despite the reduced dietary intake, indicating a systemic dysregulation of host metabolism. During cachexia, the organism is maintained in a constant negative energy balance. This can rarely be explained by the actual energy and substrate demands by tumors in patients with cancer. Overall, the cachectic profile is significantly different than that observed during starvation. Cachexia may result not only from anorexia and a decreased caloric intake but also from malabsorption and losses from the body (ulcers, hemorrhage, effusions). In any case, the major deficit of a cachectic organism is a negative energy balance. Cytokines are proposed to participate in the development and/or progression of cachexia-anorexia; interleukin-1, interleukin-6 (and its subfamily members such as ciliary neurotrophic factor and leukemia inhibitory factor), interferon-gamma, tumor necrosis factor-alpha, and brain-derived neurotrophic factor have been associated with various cachectic conditions. Controversy has focused on the requirement of increased cytokine concentrations in the circulation or other body fluids (e.g., cerebrospinal fluid) to demonstrate cytokine involvement in cachexia-anorexia. Cytokines, however, also act in paracrine, autocrine, and intracrine manners, activities that cannot be detected in the circulation. In fact, paracrine interactions represent a predominant cytokine mode of action within organs, including the brain. Data show that cytokines may be involved in cachectic-anorectic processes by being produced and by acting locally in specific brain regions. Brain synthesis of cytokines has been shown in peripheral models of cancer, peripheral inflammation, and during peripheral cytokine administration; these data support a role for brain cytokines as mediators of neurologic and neuropsychiatric manifestations of disease and in the brain-to-peripheral communication (e.g., through the autonomic nervous system). Brain mechanisms that merit significant attention in the cachexia-anorexia syndrome are those that result from interactions among cytokines, peptides/neuropeptides, and neurotransmitters. These interactions could result in additive, synergistic, or antagonistic activities and can involve modifications of transducing molecules and intracellular mediators. Thus, the data show that the cachexia-anorexia syndrome is multifactorial, and understanding the interactions between peripheral and brain mechanisms is pivotal to characterizing the underlying integrative pathophysiology of this disorder.

The paper highlights a series of questions that doctors need to consider when faced with end-stage cancer patients with bowel obstruction: Is the patient fit for surgery? Is there a place for stenting? Is it necessary to use a venting nasogastric tube (NGT) in inoperable patients? What drugs are indicated for symptom control, what is the proper route for their administration and which can be administered in association? When should a venting gastrostomy be considered? What is the role of total parenteral nutrition (TPN) and parenteral hydration (PH)? A working group was established to review issues relating to bowel obstruction in end-stage cancer and to make recommendations for management. A steering group was established by the (multidisciplinary) Board of Directors of the European Association for Palliative Care (EAPC) to select members of the expert panel, who were required to have specific clinical and research interests relating to the topic and to have published significant papers on advanced cancer patients in the last 5 years, or to have particular clinical expertise that is recognised internationally. The final constitution of this group was approved by the Board of the EAPC. This Working Group was made up of English, French and Italian physicians involved in the field of palliative care for advanced and terminal cancer patients; and of English, American and Italian surgeons who also specialized in artificial nutrition (Dr. Bozzetti) and a professor of health economics. We applied a systematic review methodology that showed the relative lack of RCTs in this area and the importance of retrospective and clinical reports from different authors in different countries. The brief was to review published data but also to provide clinical opinion where data were lacking. The recommendations reflect specialist clinical practice in the countries represented. Each member of the group was allocated a specific question and briefed to review the literature and produce a position paper on the indications, advantages and disadvantages of each symptomatic treatment. The position papers were circulated and then debated at a meeting held in Athens and attended by all panel members. The group reviewed all the available data, discussed the evidence and discussed what practical recommendations could be derived from it. An initial outline of the results of the review and recommendations was produced. Where there were gaps in the evidence, consensus was achieved by debate. Only unanimous conclusions have been incorporated. Subsequently the recommendations were drawn together by Carla Ripamonti (Chairperson) and Robert Twycross (Co-Chair) and refined with input from all panel members. The recommendations have been endorsed by the Board of Directors of the EAPC. It was concluded that surgery should not be undertaken routinely in patients with poor prognostic criteria, such as intra-abdominal carcinomatosis, poor performance status and massive ascites. A nasogastric tube should be used only as a temporary measure. Medical measures such as analgesics, anti-secretory drugs and anti-emetics should be used alone or in combination to relieve symptoms. A venting gastrostomy should be considered if drugs fail to reduce vomiting to an acceptable level. TPN should be considered only for patients who may die of starvation rather than from tumour spread. PH is sometimes indicated to correct nausea, whereas regular mouth care is the treatment of choice for dry mouth. A collaborative approach involving both surgeons and physicians can offer patients an individualized and appropriate symptom management plan.
