Uterine disorders diagnosed by ventrotomy in 47 rabbits.

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.

A case of chronic wasting disease in an elk imported to Korea from Canada.

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.

Clinical and hematological findings on "Degnala", a disease of buffalo in Eastern Nepal.

A buffalo disease, called "Degnala", causing lameness, edema, gangrenous ulceration of hooves or tail, emaciation, recumbency and eventual death, occurs in Eastern Nepal. Clinical examinations manifested lice eggs on hairs, bradycardia, hypothermia, dehydration, exanthema and icterus. Hematologically, increase of band neutrophil, giant platelet, hypoalbuminemia and hyperglobulinemia were characteristics. Microscopically, dark blue tiny particles were seen on red blood cell (RBC) after Giemsa staining. Administration of tetracycline at an early stage of the disease was effective.

Aspergillus fumigatus infection in an ostrich (Struthio camelus).

An 11-month-old female ostrich (Struthio camelus) had become gradually emaciated over a 2-week period and subsequently died. Necropsy revealed white to green mold growth on the walls of caseous thickened air sac membranes and multiple white necrotic foci in the lungs and liver. Histologically, the multiple exudative, necrotic and granulomatous lesions were compatible with mycotic infection in the air sacs and lungs, and hyphae positively reacted with a monoclonal antibody (Mab-WF-AF-1) to Aspergillus fumigatus wall fractions. Multifocal hepatic necrosis was also found, and several spores were observed in the blood vessels. Fungal culture of these lesions yielded pure growth of A. fumigatus. This is an established case of fatal A. fumigatus infection in an ostrich reared in Japan.

Pathology of experimental chlamydiosis in chicks.

Twelve one-day-old chicks were experimentally inoculated with Chlamydia psittaci derived from turkeys. Acute chlamydial septicemic lesions were induced by the inoculation into the air sac and trachea. No lesions were produced by the esophageal injection. Clinically, the affected chicks showed emaciation and mouth breathing, and were inactive while some birds died. Grossly, they had hepatomegaly, splenomegaly and airsacculitis. Histopathologically, fibrinopurulent airsacculitis, pneumonia and bronchitis, multiple fibrinous serositis in the hepatic and splenic capsules, peri- and epicardium, and mesenterium, focal endoarteritis in the aortae, activation of reticuloendothelial cells in the spleen, and hepatic necrosis were noted. Immunohistochemically, chlamydial antigen granules were present in the cytoplasm of epithelial cells of the respiratory system, hepatocytes, macrophages in the air sac, lung, serous membrane, liver, spleen, aortae, reticuloendothelial cells in the spleen, and mesothelial cells in various organs or tissues. Chlamydial multiplication in the cells of the organs or tissues involved was preceded to form the lesions.

Altered mitogen response of peripheral blood lymphocytes in different stages of feline immunodeficiency virus infection.

To elucidate relationship between disease progress and immunologic alteration in feline immunodeficiency virus (FIV) infection, we classified naturally infected cats into clinical stage groups using the working criteria modified from those for human immunodeficiency virus (HIV) infection. Among the five distinct stages described for HIV infection, the three phases; asymptomatic carrier (AC), AIDS related complex (ARC), and acquired immunodeficiency syndrome (AIDS), were evaluated for concanavalin A (Con A)-induced lymphocyte blastogenic activities by using glucose consumption assay. There was a significant decrease of lymphocyte response in AC phase. The loss of response became marked as the disease progressed to ARC and AIDS, with an almost complete loss of mitogen response in AIDS phase. In addition to the loss of a lymphocyte function, AIDS in FIV infection was characterized by marked emaciation, anemia or pancytopenia, and postmortem evidences of opportunistic infections and lymphoid depletion.

Nursing management of nutrition in cancer and palliative care.

Malnutrition is prevalent in patients with cancer. This can have deleterious effects including reduced response to treatment, diminished quality of life, increased length of hospital stay and decreased survival. It is, therefore, imperative that thorough nutritional screening is carried out by nurses on patients' admission and during their hospital stay to detect those who are malnourished or at risk of malnutrition in order to plan their nutritional care effectively. Cancer cachexia is the progressive weight loss and emaciation seen in cancer patients, particularly in advanced disease, which can have a devastating effect on the physical, psychological, social and spiritual aspects of the patient's life. Therefore, the aims of nutritional care are identified depending on the stage of the patient's illness and recommendations made for nursing, pharmacological and nutritional intervention. These include nursing comfort strategies, the use of recommended pharmacological agents and dietary interventions such as experimenting with different foods, textures, portion sizes and nutritional supplements. The use of fish oil-enhanced nutritional supplements and artificial nutritional support is also discussed. Consideration is also given to the legal and ethical aspects of providing nutrition and nutritional support.

Measurement of body size and shape perception in eating-disordered and control observers using body-shape software.

A disturbance in the perception of personal body size and shape is a key feature of both anorexia and bulimia nervosa, but it has proved difficult to quantify. Previous attempts have used methods like the distorting video technique (DVT), which alters an image by stretching the figure in either the X- or Y-axis. This is a poor representation of the way fat is added to or lost from the body, and the pattern of distortion provides a host of cues to the degree to which the image has been altered. To overcome these problems we have used a specially designed software system that uses biometric data based on real body shapes, instead of simply stretching or compressing images of bodies. This technique also allows individual body parts to be altered separately, so we can determine whether a specific body part is overestimated relative to others. We can also calculate the apparent body mass index (BMI) of our modified pictures, using the perimeter-area ratio (PAR). This allows us to compare an observer's actual BMI with that calculated for their estimated and ideal bodies. We tested 30 anorexic, 30 bulimic and 137 control observers. Our results show that all three observer groups tend to overestimate their body size, but not significantly so. Both the control and bulimic observers prefer an ideal body with a BMI of 20, which is at the lower end of the 'normal' BMI range. However, the anorexics ideal BMI is 15, which is on the border between the emaciated and underweight BMI categories.

Morbilliviral dermatitis in seals.

A juvenile female hooded seal (Cystophora cristata) and a juvenile male harp seal (Phoca groenlandica) stranded separately on the New Jersey (USA) coast and were taken to a marine mammal rehabilitation center. Both were lethargic and emaciated, had dermatitis, and died. Histologic skin lesions in the seals were similar and consisted of epidermal and follicular epithelial hyperplasia, hyperkeratosis, degeneration, and necrosis. The most distinctive finding was extensive syncytial zones bounded superficially by hyperkeratosis and deeply by hyperplastic basal cells. Eosinophilic intracytoplasmic inclusion bodies were present in epithelial cells. Morbilliviral antigen was demonstrated in the skin lesions by immunohistochemistry. Phocine distemper virus was detected in the skin by reverse transcription polymerase chain reaction and a phocine distemper virus-specific probe using the Southern blot technique. This is the first report of morbilliviral dermatitis in marine mammals.

Immunohistochemical evaluation of a malignant intestinal carcinoid in a dog.

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.

Obliterative endophlebitis in mute swans (Cygnus olor) caused by Trichobilharzia sp. (Digenea: Schistosomatidae) infection.

Schistosome infections in mammals cause chronic proliferative vascular lesions associated with the presence of adult parasites in the lumen of mesenteric and portal veins. In birds, however, this has never been reported. In this study, we found obliterative endophlebitis associated with the presence of adult schistosomes (Trichobilharzia sp., probably Trichobilharzia filiformis) as the main pathologic finding in five of eight mute swans (Cygnus olor). On histologic examination, the intestinal and portal veins of these swans showed moderate to severe, diffuse, hyperplastic endophlebitis, characterized by myointimal hyperplasia, often with obliteration of the vascular lumen. In addition, moderate to severe lymphocytic and granulocytic enteritis occurred in all eight swans associated with the presence of schistosome eggs in the intestinal mucosa. Other findings included hepatic and splenic hemosiderosis and high hepatic copper levels. The vascular lesions associated with Trichobilharzia sp. infection may have contributed to the emaciation and death of those mute swans by obstruction of venous return in the intestinal and portal veins.

Renal adenocarcinoma in a ferret.

A spontaneous case of renal tumor was observed in a 7-year-old ovariectomized female pet ferret (Mustela putorius furo). Clinical signs included exhaustion, emaciation, anorexia, and stooping position. At necropsy, a solid and cystic mass replaced the left kidney and adrenal gland. The tumor was composed of pleomorphic epithelial cells with a large number of giant cells. Metastases were recognized in the lung, liver, greater omentum, right renal pelvis, and systemic lymph nodes. Immunohistochemical stains revealed that the tumor cells were positive for CD10, cytokeratin (CAM 5.2), and Ki-67 (MIB-1). On the basis of morphologic and immunohistochemical features, the tumor was diagnosed as a pleomorphic renal adenocarcinoma. This type of neoplasm is very rare in all species and has never been reported in a ferret.

Neuronal storage disease in a group of captive Humboldt penguins (Spheniscus humboldti).

A neuronal storage disease affecting 5 captive Humboldt penguins is described. One bird died after 3 days of lethargy and anorexia. The 4 remaining birds died after a slowly progressing course of disease with signs that included lethargy, weakness, and neurologic dysfunction. Neurologic signs included dysphagia and ataxia. Gross lesions in the first animal to die consisted of hepatosplenomegaly indicative of avian malaria, which was confirmed histologically. The 4 remaining animals were mildly to moderately emaciated. Moderate to marked vacuolation of the neuronal perikarya was observed in Purkinje cells, neurons of the brainstem nuclei, and motorneurons of the spinal cord in all birds. By electron microscopy the vacuoles represented multilayered concentric lamellar structures. These findings were indicative of sphingolipidosis. All animals had been prophylactically treated for avian malaria, aspergillosis, and possible bacterial infections with chloroquine, itraconazole, and enrofloxacin. Circumstantial evidence implicates chloroquine therapy as the possible cause of the storage disease.

[Primary plasmacytoma of the thyroid--report of an autopsy case and review of the literature in Japan].

Primary extramedullary plasmacytoma (PEMP) of the thyroid is rare. Only nine patients with PEMP of the thyroid have been reported in Japan to date. We describe an additional autopsy case with PEMP of the thyroid and review of the literature in Japan. A 67-year-old women complaining of swelling of the anterior neck exhibited thin scalp hair, edematous face and a giant, hard, nodular goiter. Laboratory examination showed elevated levels of ESR, collagenous reaction, gammaglobulin, and a M-bow of the IgG-k type in immunoelectrophoresis. No Bence-Jones protein was found in the urine. Thyroid function test revealed a subclinically hypothyroid state, showing a T3 of 1.32 ng/ml, a T4 of 10.0 micrograms/dl, a TSH of 23.4 microU/ml and positive thyroid antibodies. The scintigram and the CT scan of the thyroid showed deviation of the trachea by the thyroid tumor and calcification within homogeneous thyroid gland. She underwent total thyroidectomy because of suspected malignancy. The histological examination of the removed thyroid weighing 117gr revealed a proliferation of plasma cells and lymphocytes and small amounts of atrophied thyroid follicles. The immunohistological examination of the removed thyroid showed the monoclonality to IgG-k chain. Plasma cells were stainable with methylgreenpyronine. Twenty-six months after thyroidectomy, she died due to progressive emaciation, anemia, hypoalbuminemia and ascites. Postmortem examination revealed widespread metastasized plasma cell tumors in the liver, intestine, spleen and mesentery with ischemic changes in heart and kidney. Based on our autopsy case and the nine cases reported in Japan, clinical and histological characteristics of PEMP of the thyroid were discussed.

[A case of type 1 diabetes mellitus with hypothalamic amenorrhea: successful pregnancy following subcutaneous pulsatile administration of LHRH].

A 27-year-old woman with type 1 diabetes mellitus was admitted to the Shimane Medical University Hospital because of secondary amenorrhea. She had been treated with insulin since July, 1986. Fasting plasma glucose and HbA1c levels were controlled within normal limits. However, body weight gradually decreased and amenorrhea started in 1988. Physical examination revealed emaciation with BMI of 17.3. Basal levels of plasma T3, somatomedin C, LH, FSH and estradiol levels were low, whereas HGH levels were slightly elevated. Plasma LH markedly increased in response to LHRH administration. She was diagnosed as having weight loss-related hypothalamic amenorrhea. Induction of ovulation was not obtained with clomiphene citrate. Treatment with subcutaneous pulsatile administration of LHRH (20 micrograms every 120 min) resulted in an increase in plasma levels of LH, FSH and estradiol, which was accompanied by ovulation and corpus luteum formation. Further treatment with pulsatile LHRH administration was followed by conception. Two gestational sacs were detected by ultrasonography. One of them was absorbed at the early stage of pregnancy. She was delivered of one healthy female infant without complications. These findings suggest that it is important not only to control plasma glucose levels but to keep the appropriate weight and support the psychological aspects of the subject in the treatment of diabetes mellitus. Subcutaneous pulsatile LHRH therapy may be effective for the induction of ovulation in clomiphene-resistant hypothalamic amenorrhea; however, it will be necessary to solve the problem of dosage and the interval of LHRH administration in the future.

A male patient presenting with major clinical symptoms of glucocorticoid deficiency and skeletal dysplasia, showing a steroid pattern compatible with 17alpha-hydroxylase/17,20-lyase deficiency, but without obvious CYP17 gene mutations.

We report the case of a 17-year-old boy with delayed puberty, who presented a complexity of clinical problems. An analysis of steroid hormones led to a diagnosis of 17alpha-hydroxylase/17,20-lyase deficiency (17OHD). Unlike typical cases of 17OHD, however, the patient had pubertal development without medical intervention. In addition, he never exhibited the symptoms of mineralocorticoid excess, showing instead the symptoms of glucocorticoid deficiency, including fatigability, emaciation, and weight-loss induced by minor infection. He also had dysmorphic features, which comprised marfanoid habitus, arachnodactyly and putative craniosynostosis. The combination of these malformations substantially resembled that of Shprintzen-Goldberg syndrome. Direct sequencing of the CYPl7 gene did not reveal any significant aberrations in the exons or exon-intron boundaries. We speculate that the association of partial combined 17OHD with the Shprintzen-Goldberg phenotype in the present patient may result from an aberration of a hitherto unknown gene that controls both steroid hormone synthesis and skeletal development.

Catecholamine and thyroid hormone metabolism in a case of anorexia nervosa.

Alterations in catecholamine (CA) and thyroid hormone metabolism were examined in a 12-year-old girl with anorexia nervosa during 3 months of treatment. According to her body weight change, the observation period was divided into 3 stages: initial emaciation (stage 1), stable maintenance of the -30% level of the previous weight (stage 2) and convalescent stage (stage 3). Stage 1 was characterized by relatively high urinary norepinephrine (NE) and epinephrine (E) but low dopamine (DA) excretion, elevated plasma DA-beta-hydroxylase (DBH) activity and reduced serum thyroid hormones, especially the triiodothyronine (T3) level. In stage 2, urinary CAs were markedly suppressed, while serum thyroid hormones gradually increase. In stage 3, a great increase in DA excretion, a fall in plasma DBH activity and normalization of thyroid hormones were observed. In the low T3 state below 60 ng/dl, urinary NE + E/DA ratios were elevated and widely fluctuated (0.58 +/- 0.30, SD), but were gradually decreased and completely stabilized in the normal T3 state (0.07 +/- 0.02, P less than 0.001). These results indicate that (1) although total CA production was depressed in anorexia nervosa, a change from an adrenergic-dominant to a dopaminergic-dominant state occurs in accordance with body weight gain, and (2) this shift in the CA profile is associated with concomitant recovery of reduced thyroid hormone concentrations. Thus, as for the energy expenditure, compensatory changes were observed in CAs and thyroid hormones in relation to caloric restriction.

Update on endocrine disturbances in anorexia nervosa.

The marked endocrine changes that occur in anorexia nervosa have aroused a great deal of interest, and over the last decade much research has been conducted in this field. The endocrine disturbances are not specific to this disorder, as they also occur in starvation states secondary to other causes, and they return to normal upon weight restoration. However, emaciation may have profound effects on psychological processes, establishing an intricate circular interaction whereby somatic and psychological manifestations of starvation may continue to act. The purpose of this paper is to provide an overview of the large body of literature concerning endocrine aspects of anorexia nervosa with the main focus on the latest results, which provide leads for potential etiological theories.
