We report here a case of hepatic focal nodular hyperplasia (FNH) associated with hepatic hemangioma and multiple hepatic cysts in a 71-year-old man. He was admitted to our hospital because of body weight loss. Ultrasonography detected multiple cysts. and two tumors in the liver one, 3.5 cm and one, 1.6 cm. Color Doppler ultrasonography showed arterial signals within the large tumor. On dynamic computed tomography, the large tumor was a hypodense lesion which was enhanced during the arterial phase and almost isodense during the delayed phase: the small tumor was also a hypodense lesion, and was enhanced during both the arterial and delayed phases. On magnetic resonance imaging using superparamagnetic iron oxides, the large tumor had decreased signal intensity on the T2-weighted image. On hepatic arteriography, the feeding artery of the large tumor showed a spoke-wheel appearance and that of the small tumor showed a cotton-wool appearance. Ultrasonographically guided fine-needle aspiration biopsy of the large tumor revealed hepatocellular hyperplasia. Finally, we diagnosed the two hepatic tumors as FNH and hemangioma. There was no intracranial lesion. The cause of the patient's emaciation was psychogenic anorexia. To our knowledge, this is the first case report that describes the simultaneous occurrence of these three kinds of hepatic lesions. The pathogenesis of FNH still remains unclear, but this association suggests that FNH may arise because of a vascular anomaly.

Anorexia nervosa is considered an enigmatic disease with a multitude of predisposing factors and no empirically confirmed effective treatment. However, all people with the disease relentlessly pursue a common idealized goal--the state of severe emaciation. In this article, the perspective that this condition epitomizes a life-time struggle for self-acceptance and self-definition is reexamined. People afflicted with anorexia come to define themselves through their emaciated form, and maintenance of this form becomes their major focus and primary means of fulfillment. Therapy must address the identity issue, which is fundamental to the onset and perpetuation of the disease. Use of interpersonal techniques is advocated as most appropriate in serving this purpose.

The type, ages of occurrence, primary complaints, clinical signs and mortality in forty-seven cases of uterine disorders diagnosed by ventrotomy in rabbits were analyzed retrospectively. Endometrial hyperplasia (29.8%) was most frequently observed, followed by uterine adenocarcinoma (21.3%). Tumorous lesions were seen in 46.8% of the cases. The age of occurrence ranged from two years and two months to seven years and six months, with a peak at four to five years of age. The most common primary complaint was bleeding (62.2%), followed by mammary gland abnormality (12.8%) and increased abdominal circumference (10.6%). Physical examinations revealed mammary gland disorders such as mammary cysts in 31.9% of the cases. Uterine disorders were detected by palpation in 15 out of 32 cases with a primary complaint of bleeding. Ultrasonography showed uterine disorders in 21 out of 24 cases, suggesting that ultrasonography could be useful in the diagnosis of uterine disorders. The outcome seemed to be influenced by physical status rather than malignancy of lesions. The mortality was higher in cases with symptoms such as anorexia, emaciation, severe anemia, and dehydration.

Forty-six cats with clinical haemobartonellosis were studied; 75 per cent of the cats of known age were two-and-a-half years old or younger, 50 per cent were intact males and 19.5 per cent were castrated males. The predominant signs of the disease were tachypnoea, lethargy, depression, anorexia, infestation with fleas, pale mucous membranes, icterus, emaciation, dehydration, splenomegaly, anaemia, leucocytosis, increased activities of alanine aminotransferase and aspartate aminotransferase, and azotaemia. Thirty-eight per cent of the cats that were tested for feline leukaemia virus (FeLV) antigen were positive, and 22 per cent of those tested for feline immunodeficiency virus (FIV) antibodies were positive. The prevalence of both FeLV and FIV was much higher than in the general Israeli cat population. The cats infected with both Haemobartonella felis and FeLV had a significantly lower body temperature, were more anaemic and the mean cell volume of their erythrocytes was greater than in the cats with haemobartonellosis alone.

This study involved 14 ostriches of both sexes between 3 and 24 mo of age. Some hematologic and biochemical parameters were studied in animals with stomach impaction. Clinical examination of the birds revealed anorexia, emaciation, decreased defecation, listlessness, separation from the flock, and recumbence. The total number of leukocytes (10.4 x 10(3) mm3), the concentrations of serum glucose (166 mg/dl), and total protein (2.4 g/dl) decreased; serum creatine phosphokinase (1240 U/L) and alkaline phosphatase (598 U/L) increased; whereas no changes were found in the concentrations of calcium, phosphorus, magnesium, zinc, and copper. Medical treatment was initiated in 13 animals; six of them recovered and seven birds died. Necropsy revealed edema, erosions, and hemorrhagic ulcers in the stomach of the dead birds. Foreign bodies such as sand; stone; pieces of wood, glass, and plastic; and metallic objects were encountered in the stomach at the necropsy. In one bird, metallic foreign body was diagnosed and the bird was referred to surgery. Under stress factors, ostriches tend to eat foreign material; therefore, adequate housing, nutrition, and care are crucial in prevention of stomach impaction.

A seven-year-old male elk (Cervus elaphus nelsoni) was euthanized and necropsied after having a 3-week history of body weight loss, emaciation, excessive salivation, teeth grinding, fever, anorexia, and respiratory distress. The elk was imported into Korea from Canada on March 9, 1997. Gross pathologic findings were restricted to a diffuse fibrinous pneumonia. Microscopic lesions included mild neuronal vacuolation and spongiform change in the neuropil of selected brain stem nuclei and generalized astrocytosis. Immunohistochemistry for protease-resistant prion protein (PrP(res)) was positive in all brain sections but more pronounced in the section of the obex of the medulla. And the PrP(res) was also detected by western immunoblotting in the brain and spinal cord. All the remaining elk and deer that had been in contact with this elk were destroyed and negative for chronic wasting disease (CWD). To our knowledge, this is the first case of CWD occurring outside of the U.S.A. and Canada.

A case of tuberculosis is reported in an eight-year-old, male, elk (Cervus elaphus nelsoni). The elk showed severe coughing, respiratory distress, abdominal breathing, anorexia, and severe progressive emaciation in the elk farm. At necropsy, the elk appeared in poor body condition. Mild enlargement of retropharyngeal and submandibular lymph node was observed in the head. Diffuse fibrinous pleuritis and purple red lobar pneumonia were found in the thorax. Well demarcated numerous dark yellow discrete or confluent nodules from 0.3 to 2 cm in diameter were scattered in the whole lung. Bronchial and mediastinal lymph nodes were also enlarged. Histopathologically, lungs had typical classical tuberculous granulomas, multiple abscesses, and numerous macrophages and Langhans giant cells infiltration in alveolar lumen. In the lymph nodes, there were small clusters of necrosis and infiltration of numerous macrophages, epithelioid cells, and Langhans giant cells. With the acid-fast staining, numerous mycobacteria were revealed in the lung and lymph nodes. According to this study, there are differences of the histopathologic lesions and the numbers of acid-fast bacilli in the lesions between this elk and cattle. Mycobacterium bovis was confirmed as a causative agent in this elk using bacterial isolation, biochemical characteristics, and PCR technique. The isolate was negative for niacin test, nitrate reductase, and pyrazinamidase. This is a first report for bovine tuberculosis of farmed elk in Asia.

An intestinal carcinoid with multiple metastases was identified in a 5-year-old male Shih Tzu with a clinical history of anemia, fatigue, anorexia, vomiting, intermittent diarrhea, intestinal bleeding, and progressive emaciation. There was a yellowish-white mass 15 mm in diameter in the anterior jejunum and white nodules consistent with metastases in many organs. Histopathologically, the mass consisted of neoplastic cells arranged in lobules, trabeculae, or closely interdigitating islands of cells. Neoplastic cells were generally polygonal with round hyperchromatic nuclei, modest amounts of eosinophilic cytoplasm, and eosinophilic cytoplasmic granules. Mitoses were common. Rosette formations of tumor cells were apparent in metastatic tumors. Immunohistochemically, tumor cells stained positive for cytokeratin 13, synaptophysin, protein gene product 9.5, neuron-specific enolase, chromogranin A, calcitonin gene-related peptide, serotonin (5-HT), and Leu-7. Serum 5-HT concentrations for this dog were increased 10-fold compared with those of normal dogs. All findings were consistent with a diagnosis of a malignant intestinal carcinoid.

Patients with anorexia nervosa (AN) often show normal to elevated physical activity levels despite severe weight loss and emaciation. This is seemingly in contrast to the loss of energy and fatigue characteristic of other starvation states associated with weight loss. Despite the fact that historical accounts and clinical case studies of AN have regularly commented on the elevated activity levels, the behavior has become only recently the subject of systematic study. Because rodents and other species increase their activity upon food restriction leading to weight loss when given access to an activity wheel--a phenomenon referred to as activity-based anorexia or semi-starvation-induced hyperactivity (SIH)-it has been proposed that the hyperactivity in AN patients may reflect the mobilization of phylogenetically old pathways in individuals predisposed to AN. Exogeneous application of leptin in this animal model of AN has recently been shown to suppress completely the development of SIH. Hypoleptinemia, as a result of the food restriction, may represent the initial trigger for the increased activity levels in AN patients and in food-restricted rats. In the first and second parts of our review, we will summarize the relevant findings pertaining to hyperactivity in AN patients and in the rat model, respectively. We conclude with a synopsis and implications for future research.

Members of a wild-caught colony of 16 gray-crowned rosy finches (Leucosticte tephrocotis) were presented with dermal and mucosal lesions, anorexia, emaciation, lethargy, and sudden death. Lesions included dermatitis, conjunctivitis, and glossitis. Skin scrapings from and bacterial culture of dermal lesions yielded Staphylococcus aureus and Candida albicans. Necropsy and histologic examination revealed characteristic epidermal and mucosal pox lesions, with the presence of characteristic Bollinger body intracellular inclusions. Electron microscopy (EM) provided confirmation of pox virus infection. This epornitic resulted in the death or euthanasia of 12 birds (75% morbidity and associated mortality) and was brought to conclusion through culling of affected birds. The source of infection remains unknown, although multiple modes of introduction exist. Similar epornitics may be prevented through indoor, species-specific housing, and quarantine. Vaccination and antiparasitic treatment may reduce the risk of disease spread.
