Thirty pigeons were experimentally infected with Streptococcus bovis using an intravenous infection model. Ninety percent of the inoculated pigeons developed clinical disease. Disease signs included acute death, inability to fly, lameness, inappetence, emaciation, polyuria, and the production of slimy, green droppings. At necropsy, the septicemic character of the disease was evident. Typical lesions included extensive well-circumscribed areas of necrosis in the pectoral muscle, tenosynovitis of the tendon of the Musculus pectoralis profundus, and arthritis of the stifle, tibiotarsal, or shoulder joints. Focal myocardial necrosis also was seen. Meningitis and encephalitis occurred in the cerebrum and the cerebellum. Disease signs and lesions described here after experimental infection were similar to those in naturally occurring cases of S. bovis septicemia.

A case of Encephalitozoon cuniculi infection in a rabbitry is reported. After the introduction of new rabbits in 1984, problems arose accompanied by serious losses among rabbits of all ages. Affected animals showed muscular weakness, emaciation, polydipsia and polyuria and died within various periods. Some of the affected animals also showed neurological symptoms. When two animals were examined at autopsy lesions typical of encephalitozoonis were observed: small granulomas in the brain and chronic interstitial nephritis associated with tubular degeneration. Encephalitozoon cuniculi was identified in the affected renal tubules and, in small numbers, also in the brain and the liver. The pathogenesis, epidemiology and possibilities of control are briefly discussed.

Almost all the male animals of WBN/Kob rat strain show the diabetic syndrome whereas none of the female animals develop such diseased conditions even at elder age. We investigated the effect of sex hormones on the onset of diabetic syndrome of this rat strain by comparing the results of body weight gain and various clinical tests such as glucose tolerance, serum biochemistry and histopathology of spayed female rats with those of non-treated and sham-operated female animals kept until 88-week-old. Non-treated and sham-operated female animals had shown no abnormal result even at 88-week-old. Spayed female animals began to reveal glucosuria associated with polydipsia and polyuria from 72-week-old, and gradually developed emaciation and cataract. Increased body weight gain, impaired glucose tolerance and lasting hyperglycemia were observed prior to the onset of the symptoms. Pancreatic changes consisted of atrophy of acinar tissue and atrophy or disappearance of islet tissue attributable to clinical data also were detected in spayed female animals. These diabetic syndrome and pancreatic change were analogous to those of aged male WBN/Kob rats but the onset of spayed females was delayed and less severe. Present results suggest that female sex hormones are protective from the onset of diabetic syndrome of WBN/Kob rats.

Subacute toxicity of captopril by daily oral administration at dose levels of 10 mg/kg, 30 mg/kg, 100 mg/kg, 300 mg/kg, 900 mg/kg and 2700 mg/kg for one month was studied in Sprague-Dawley rats. In the 2700 mg/kg group, 13 of 18 males and 17 of 18 females died with marked emaciation and abdominal distension. In the 900 mg/kg group, 1 of 18 males and 3 of 18 females died also during the administration period. In dead animals, a marked dilatation of gastrointestinal tract was noted showing multiple hemorrhagic erosions and/or ulcers in the glandular stomach. The remainder of these groups exhibited polydipsia and polyuria during the dosage period. In the 300 mg/kg and 100 mg/kg groups, all animals survived throughout the entire experimental period showing polydipsia and polyuria. In the 30 mg/kg and 10 mg/kg groups, all animals survived also throughout the entire dosage period without showing any toxic sign. Regarding plasma analysis, the BUN and creatinine concentration was significantly elevated in the group of 100 mg/kg or more. In the hematological examination, there was a decrease of erythrocyte counts, hemoglobin contents and hematocrit values in the group of 300 mg/kg or more. Pathological examinations revealed a marked thickening of the wall in afferent arterioles and interlobular arteries of the kidney in association with hypertrophy and hyperplasia of juxtaglomerular cells in 100 mg/kg, 300 mg/kg, 900 mg/kg and 2700 mg/kg groups. In these groups, multiple hemorrhagic erosions with or without ulcer were also noted in the glandular stomach. In the spleen, a slight increase of extramedullary hematopoiesis and hemosiderosis was noted in the 100 mg/kg, 300 mg/kg, 900 mg/kg and 2700 mg/kg groups, in which an increase of erythropoietic elements was also noted in the bone marrow. From these results, the maximum nontoxic dose was estimated as about 30 mg/kg/day by oral administration of captopril in the rats.

In a first experiment, the relative virulence for pigeons of 5 strains of S. bovis was assessed by experimental inoculations. Two S. bovis serotype 1 strains, one serotype 2 strain and two serotype 3 strains were examined. One of the serotype 1 strains and the serotype 2 strain were isolated from pigeons that died from septicaemia. The other strains were isolated from cloaca samples of healthy pigeons. For each strain, 10-20 pigeons were intravenously inoculated with 1 x 10(9) CFU. Morbidity after infection with the serotype 1 and 2 strains varied between 75% and 90%. Disease signs included inability to fly, lameness, emaciation, production of slimy, green droppings, polyuria and sudden death. In groups of pigeons inoculated with the serotype 3 strains, morbidity was 0% and 6%, respectively. Results demonstrate that serotype 3 strains are less virulent for pigeons than serotype 1 and 2 strains. In a second experiment, bacteriological and histological examinations were performed on organs of pigeons serially killed between 1 and 10 days after experimental inoculation with an S. bovis serotype 3 strain of low virulence. Results were compared with results of studies carried out with a highly virulent serotype 1 strain. Notwithstanding bacterial spread and replication in various organs of inoculated pigeons, clinical disease was not observed and histological lesions were scarce and of limited extent.

Pathomorphologic studies were carried out on three cases of bovine diabetes mellitus with clinical signs of polydipsia, polyuria, severe emaciation, glycosuria, persistent hyperglycemia, and decreased glucose tolerance. At necropsy, two animals had atrophy of the pancreas, whereas other visceral organs, including the endocrine organs, showed no significant changes. Microscopically, there was atrophy and reduced numbers of pancreatic islets accompanied by interlobular and interacinar fibrosis and compensatory enlargement of some remaining islets. Lymphocytes were observed commonly around and within atrophic islets and occasionally around and within enlarged islets. Vacuolar degeneration with occasional accumulation of glycogen granules was observed in the beta-cells of these enlarged islets. Immunohistochemical studies of atrophic islets demonstrated complete loss of beta-cells or only a few small beta-cells. There also was a corresponding decrease in the number of cells that stained with anti-glucagon (alpha-cells) or anti-somatostatin (delta-cells) antibodies. The vacuolated cells in the enlarged islets stained strongly with anti-insulin antibody (beta-cells). Ultrastructurally, the majority of cells in the atrophic islets had reduced cytoplasmic volume and few secretory granules, features consistent with alpha-cells. In contrast, enlarged islets that had prominent immunohistochemical staining for insulin (beta-cells) consisted of beta-cells with cytosolic edema, mitochondrial swelling, dilated smooth endoplasmic reticulum, and reduced numbers of or degranulated secretory granules. These pathomorphologic features found in cattle are similar to those found in juvenile-onset insulin-dependent diabetes mellitus in human beings and suggest autoimmune involvement in diabetes.

A 9-month-old bull was presented with a history of runting and glucosuria. The bull showed major signs of diabetes mellitus, such as polyuria, polydipsia, polyphagia, emaciation, glucosuria, and ketonuria, but persistent hyperglycemia was missing. Because in an intravenous glucose tolerance test glucose disappearance was only insignificantly more rapid in a non-diabetic age-matched control than in the diabetic bull a butyrate-stimulated insulin response test was performed. Insulin response to butyrate infusion was markedly impaired in the diabetic bull compared with the non-diabetic bull. At necropsy hepatic cirrhosis was noticed and suggestive signs for diabetes mellitus were seen in liver and kidneys.

Diabetes mellitus is uncommon in infancy and newborn period. The two common forms seen are the transient and permanent forms of diabetes mellitus of the newborn. They have to be differentiated from the transient hyperglycemic states (Blood sugar > 125 mg/dl) seen in newborns who receive parenteral glucose infusions and in those with septicemia and CNS disorders. Transient diabetes mellitus of the newborn (TDNB) is defined as hyperglycemia occurring within the first month of life lasting at least 2 weeks and requiring insulin therapy. Most of these cases resolve spontaneously by 4 months. It has a reported incidence of 1 in 45,000 to 60,000 live births. The most likely etiology is a maturational delay of cAMP mediated insulin release. The clinical features include small for datedness, proneness for birth asphyxia, open-eye alert facies, dehydration, emaciation, polyuria and poydipsia. These children are prone to septicemia and urinary tract infections. They have hyperglycemia, glucosuria, absent or mild ketonuria, low basal insulin, C-peptide and IGF-1 levels. Treatment consists of hydration and judicious administration of insulin with close monitoring. Thirty percent of these children are likely to develop permanent neonatal diabetes. Compared to transient form, permanent diabetes mellitus is uncommon. It is usually due to pancreatic dysgenesis often associated with other malformations and rarely due to type 1 diabetes mellitus. The diagnosis is based on the demonstration of both exocrine and endocrine pancreatic dysfunction. These children are managed as type 1 diabetes mellitus. They are prone to develop the vascular complications of diabetes at an earlier date.

The environmental conditions and daily life in the ghettos of Europe during the holocaust are reviewed, and their effect on morbidity in different ghettos is scrutinized in an attempt to construct a typical morbidity profile. The outstanding characteristics were: crowding, shortage of basic necessities (such as food, clothing and medications), harsh environmental and sanitary conditions, inclement weather, poor personal hygiene, chronic undernutrition and malnutrition, physical and mental exhaustion. Morbidity was mainly due to infectious diseases, both endemic and epidemic outbreaks with high mortality, and high infestation rates of lice and other parasites. The dominant feature was "hunger disease" with its protean clinical expressions, endocine pathology, growth and development retardation in children, and amenorrhea and infertility among women of child-bearing age. Polyuria, nocturia and increased frequency of bowel movement were common. The typical presentation of a ghetto dweller was of extreme emaciation (a loss of up to 50% body weight); muscle weakness and skeletal abnormalities; pale, dry skin with excoriations; pedal edema; anxiety and nervousness; often goiter in children. Most of the inhabitants had some, or all, of those signs and symptoms (there were times when more than half the population was sick). This syndrome complex was termed "Ghetto Sickness" or "Ghetto Fatigue" (ghetto schwachkeit).

Diencephalic syndrome (DS) is a complex of signs and symptoms related to hypothalamic dysfunction. Its main features are emaciation despite normal energy intake and an alert appearance. This syndrome has been described in association with space-occupying lesions of the hypothalamic-optic chiasm region, mainly low-grade glioma, and less often with tumors in the proximity of the IV ventricle. Two patients with DS are reported. The first patient was an 8-month old boy with classical features of DS. Extensive investigation of malabsorption revealed no abnormalities and the first neurologic sign was a rotatory nystagmus. Magnetic resonance imaging (MRI) showed evidence of a hypothalamic tumor, which was identified after surgical resection as a pilocytic astrocytoma. The second patient was an adolescent boy who presented a 20-kg weight loss over a 6-month period and psychological disturbances. Gastrointestinal disease was ruled out as a cause of malnutrition. Because of a polydipsia-polyuria syndrome, manifest while the patient was hospitalized with a suspected diagnosis of anorexia nervosa, MRI of the brain was performed. Multiple intracranial lesions were revealed, mainly in the hypothalamus, and were identified as a disseminated disgerminoma. No neurologic signs or symptoms were present. The patients died 2 years and 1 year after diagnosis, respectively. Although DS is rare, it should be considered in severe failure to thrive or emaciation despite adequate food intake and normal absorptive function of the small bowel.
