Ten avian serotype 3 paramyxoviruses were isolated for the first time in Israel from passerine and psittacine imported caged birds. The birds were submitted for investigation of an illness characterized by nonspecific signs of weakness, anorexia, vomiting, and sneezing. In addition, only the parakeets developed specific neurologic signs. In bacteriologic and pathologic investigation, cachexia and diarrhea were observed in both groups of birds. In psittacines, considerable alterations were observed in lungs, liver, and spleen. Some nonviral pathogens were occasionally isolated. The isolates appeared to belong to serotype 3b avian paramyxovirus (APMV), the prototype strain of which is APMV-3b/parakeet/Netherlands/449/75. The isolation of APMV-3 viruses from imported caged birds may represent a way of introduction of these viruses into the country.

Sclerosing encapsulating peritonitis (SEP) is a serious complication of long-term continuous ambulatory peritoneal dialysis (CAPD), very likely related to a persisting expression of the transforming growth factor beta1 (TGFbeta1) gene on peritoneal mesothelial cells. We report the case of a 67-year-old uremic woman who developed SEP eight years after being placed on CAPD, complicated by eight episodes of bacterial peritonitis. CAPD was therefore stopped and the patient transferred to hemodialysis. The diagnosis of SEP was confirmed by physical findings (vomiting, abdominal pain with palpable mass, ileus, cachexia) and CT data. The patient was treated with tamoxifen (10 mg/day) for three months, and gradually recovered, a subsequent CT showing a significant reduction of the thickness of peritoneal and intestinal loops. Tamoxifen probably interferes with TGFbeta1 and may be useful in the treatment of this CAPD complication.

In early palliative stages effective nutrition can improve well-being. In late stages and in dying patients excessive amounts of proteins and lipids may induce nausea and vomiting, due to cachexia and subsequent changes in the metabolism. Excessive hydration may give rise to oedema and dyspnoea. In these late stages the patient rarely feels hungry or thirsty. The goal should therefore be to do good, not to harm and to respect the autonomy of the patient. Thus, the well-being of the patient should be in focus: to avoid hunger, thirst, nausea, vomiting, oedemas and dyspnoea. The consequences are that small amounts of carbohydrates and water often constitute the optimum for these patients.

Anorexia nervosa is an eating disorder among adolescent girls and young women which, though common, often goes undetected and untreated. Anorexia nervosa is a response for young people with psychological conflicts who try to win love by having a body corresponding to the present-day image, symbolising strength, beauty, attraction, power and success. Anorexia nervosa involves inadequate calorie intake leading to marked cachexia with metabolic and endocrinological disturbances. We investigated dermatological changes in 21 young female anorectics aged 19-24 in an attempt to find dermatological markers which mirror the dynamics of the disease and thus obtain helpful signs for early diagnosis with its important bearing on the outcome. Extensive histories were taken and whole-body examinations performed. Seven sex- and age-matched persons served as a control group. The most common dermatological findings were xerosis (71%, controls 29%), cheilitis (76%), bodily hypertrichosis (62%), alopecia (24%), dry scalp hair (48%), acral coldness (38%), acrocyanosis (33%), periungual erythema (48%), gingival changes (37%), nail changes (29%) and calluses on dorsum of hand due to self-induced vomiting (67%). Our study documented for the first time that a body mass index of < or = 16 (kg/m2) can be considered a critical value at which skin changes are more frequent. There are remarkable similarities between cutaneous manifestations in anorexia nervosa and in HIV infection. Patients with anorexia nervosa develop early stereotype skin changes which are cardinal diagnostic symptoms and pointers to the diagnosis of eating disorders. During training at the Department of Child and Adolescent Psychiatry in Solothurn one of us (C. H.) was once more able to observe most of the above-described cutaneous and mucocutaneous changes in anorexic adolescents. This paper is intended to stimulate further basic research on this topic. We hope our study will facilitate early diagnosis of anorexia nervosa by the family physician and enable him or her to institute immediate treatment for the eating disorder and thereby improve the prognosis.

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.

Physical symptoms other than pain often contribute to suffering near the end of life. In addition to pain, the most common symptoms in the terminal stages of an illness such as cancer or acquired immunodeficiency syndrome are fatigue, anorexia, cachexia, nausea, vomiting, constipation, delirium and dyspnea. Management involves a diagnostic evaluation for the cause of each symptom when possible, treatment of the identified cause when reasonable, and concomitant treatment of the symptom using nonpharmacologic and adjunctive pharmacologic measures. Part I of this two-part article discusses fatigue, anorexia, cachexia, nausea and vomiting. Fatigue is the most common symptom at the end of life, but little is known about its pathophysiology and specific treatment. Education of the patient and family is the foundation of treatment with the possible use of adjunctive psychostimulants. Anorexia and cachexia caused by wasting syndromes are best managed with patient and family education, as well as a possible trial of appetite stimulants such as megestrol or dexamethasone. For appropriate pharmacologic treatment, it is helpful to identify the pathophysiologic origin of nausea in each patient.

The authors carried out a research project in a nursing consultancy on patients suffering from Human Immunodeficiency Virus. Their study comprised 108 patients. The authors analysed the causes which provoke nutritional problems since the signs and symptoms derived from this disease are associated with opportunistic infections which directly affect nutritional requirements. The authors selected variables which would determine general parameters for a nutritional study: anthropological measurement parameters such as weight, height and other basic vital measurements; Biochemical parameters such as albumin and ferritin; clinical parameters such as diarrhoea, vomiting, anorexia, fever, and dysphagia. The biochemical parameters provided evidence in the albumin measurements that 65.28% of these patients suffer from severe malnutrition. With regards to anthropological measurements, basic vitals showed that 16.8 of these patients have a normal range while 52.64% fall below the 10th percentile which demonstrate important levels of cachexia. In the near future, these authors shall publish their study regarding the eating habits of these patients and its relationship to their nutritional status.

Hepatocellular carcinoma (HCC) is one of the leading causes of cancer death in Taiwan. In order to delineate the unique demographic features and clinical profile of terminal HCC, we conducted a retrospective study in a hospital-based hospice in Taiwan. Of a total of 991 terminally ill cancer patients (654 men and 337 women, mean age 66.1 years) admitted to our palliative care unit during a three-year period, 110 patients (11.1%) were diagnosed as having HCC (93 men and 17 women, mean age 60.5 years). The most common metastatic sites were bone and lung. Eighty-five HCC patients (77.3%) also had associated liver cirrhosis. The most common symptoms of HCC patients upon admission to the hospice ward were pain, fatigue or weakness, anorexia/vomiting, peripheral edema, cachexia, and ascites. Hypoalbuminemia, anemia, hyponatremia and jaundice were common laboratory abnormalities. Eighty-four patients (76.4%) required opiates for pain management. Upper gastrointestinal bleeding or varices bleeding developed in 76 patients (69.1%). Ninety-four patients (85.5%) died at the hospital, and the overall median survival time at hospice ward was 12 days. Because of more severe underlying portal hypertension and deteriorated liver function, terminal HCC patients with decompensated liver cirrhosis (Child-Pugh class C) had a significantly higher prevalence of peripheral edema, ascites, dyspnea, jaundice, thrombocytopenia, and stage III-IV hepatic encephalopathy than noncirrhotic or Child-Pugh class A and B terminal HCC patients. Symptoms and signs resulting from these portal hypertensions frequently complicated the symptomatic management of terminal HCC patients in the hospice ward. The treatment of these complications is mostly empirical in hospice ward, where intensive laboratory or diagnostic tests are usually not performed. In conclusion, symptoms and signs of terminally ill HCC patients in hospice are unique and should be managed appropriately.

BACKGROUND: Eosinophilic gastritis is related to eosinophilic gastroenteritis, varying only in regards to the extent of disease and small bowel involvement. Common symptoms reported are similar to our patient's including: abdominal pain, epigastric pain, anorexia, bloating, weight loss, diarrhea, ankle edema, dysphagia, melaena and postprandial nausea and vomiting. Microscopic features of eosinophilic infiltration usually occur in the lamina propria or submucosa with perivascular aggregates. The disease is likely mediated by eosinophils activated by various cytokines and chemokines. Therapy centers around the use of immunosuppressive agents and dietary therapy if food allergy is a factor. CASE PRESENTATION: The patient is a 31 year old Caucasian female with a past medical history significant for ulcerative colitis. She presented with recurrent bouts of vomiting, abdominal pain and chest discomfort of 11 months duration. The bouts of vomiting had been reoccurring every 7-10 days, with each episode lasting for 1-3 days. This was associated with extreme weakness and cachexia. Gastric biopsies revealed intense eosinophilic infiltration. The patient responded to glucocorticoids and azathioprine. The differential diagnosis and molecular pathogenesis of eosinophilic gastritis as well as the molecular effects of glucocorticoids in eosinophilic disorders are discussed. CONCLUSIONS: The patient responded to a combination of glucocorticosteroids and azathioprine with decreased eosinophilia and symptoms. It is likely that eosinophil-active cytokines such as interleukin-3 (IL-3), granulocyte macrophage colony stimulating factor (GM-CSF) and IL-5 play pivotal roles in this disease. Chemokines such as eotaxin may be involved in eosinophil recruitment. These mediators are downregulated or inhibited by the use of immunosuppressive medications.

Many patients with life-threatening diseases such as cancer experience severe symptoms that compromise their health status and deny them quality of life. Patients with cancer often experience cachexia, pain, and depression,which translate into an unacceptable quality of life. The discovery of the endocannabinoid system has led to a renewed interest in the use of cannabinoids for the management of nausea, vomiting, and weight loss arising either from cancer or the agents used to treat cancer. The endocannabinoid system has been found to be a key modulator of systems involved in pain perception, emesis, and reward pathways. As such, it represents a target for development of new medications for controlling the symptoms associated with cancer. Although the cannabinoid receptor agonist tetrahydrocannabinol and one of its analogs are currently the only agents approved for clinical use, efforts are under way to devise other strategies for activating the endocannabinoid system for therapeutic uses.
