The clinical and biochemical data obtained in 85 patients with diabetic ketoacidosis (DKA) are presented. DKA is an acute exacerbation of diabetes, a characteristic clinico-biochemical syndrome including increasing thirst, polyuria, adynamia, dryness of the skin and mucous membranes, anorexia, nausea, vomiting, occasionally abdominal pain, Kussmaul's breath, acetone odour in the exhaled air, circulatory collapse, prerenal azotemia, stupor, coma. Glycemia level exceeds 19 mmol/l, blood pH over 7.3. The disease is marked by neutrophilic leukocytosis, blood count shift to the left, elevated blood content of creatinine and urea. It was established that the degree of consciousness abnormality does not always correlate with the degree of the clinico-biochemical manifestations of DKA. During DKA, coma occurs relatively seldom (5.9%). It is suggested to use the term "diabetic ketoacidosis", incipient or marked, indicating the degree of consciousness abnormality (stupor, coma).

A severe total body chloride deficit was induced in Holstein calves by feeding a low-chloride ration (0.063% Cl) and removing digesta daily from the abomasum through a surgically implanted cannula. Clinical signs of the deficit observed included polydipsia, polyuria, dehydration, anorexia, scleral injection, decreased respiratory rate, and blood and mucus in the feces. Necropsy findings included dehydration, blood in the lumen of the small intestine, and renal lesions. The most extensive histopathologic changes occurred in the renal tubular epithelium of the outer medulla where mineralization of the tubular epithelium and basement membranes was frequently seen.

Ochratoxin A was isolated from a culture of Aspergillus ochraceus grown on a cornmeal substrate. The mycotoxin was added to a grower ration for 14 kg young pigs at 2, 4, 8 and 16 mg/kg and fed to groups of 3 for periods ranging from 6 to 20 days. The highest dose rate group only became sick, with loss of appetite, weight loss, polydipsia, polyuria, proteinuria, glucosuria, elevation of serum creatinine, pale swollen kidneys, renal tubular degeneration and cortical fibrosis. The pigs on the 2 mg toxin/kg of diet appeared unaffected with only slight renal tubular degeneration present in one animal. Feeding diet contaminated with the intermediate doses of 4 and 8 mg toxin/kg diet lead to reduction of weight gain and/or reduced feed intake and feed conversion efficiency as well as mild renal lesions. Ochratoxin A has recently been reported on mould-affected grain in Queensland and some local strains of A. ochraceus in culture have been shown to be able to produce levels of ochratoxin A of up to 4000 mg/kg of substrate. Rare episodes of nephrotoxicity in pigs seen at slaughter in Queensland may thus be due to prior contamination of the diet with ochratoxin A.

Chronic renal failure was diagnosed in 6 young Standard Poodles from 2 related litters. Clinically, the disease was characterized by polydipsia, polyuria, anorexia, lethargy, vomiting, and bony deformities suggestive of fibrous osteodystrophy. Laboratory evaluation revealed azotemia and hypercholesterolemia in all 6 dogs and nonregenerative anemia in 3 dogs. Two dogs had hyperphosphatemia and another 2 were hypercalcemic. Isosthenuria and proteinuria were found in both dogs for which urinalyses were available. The kidneys were characterized pathologically by interstitial fibrosis, variable interstitial infiltrates of lymphocytes and plasma cells, tubular atrophy, tubular dilatation, tubular basement membrane mineralization, cystic glomerular atrophy, and immaturity of glomeruli, with inconspicuous capillary lumens.

Concurrent diabetes mellitus and hyperadrenocorticism were diagnosed in 30 dogs over a 2-year period. Clinical signs included polyuria, hepatomegaly, polyphagia, abdominal distension, truncal alopecia, anorexia, and vomiting. Because of the similar clinical and laboratory findings for hyperadrenocorticism and diabetes mellitus, hyperadrenocorticism was initially overlooked in some dogs. Insulin resistance, characterized by high daily insulin requirements, developed in the diabetic dogs with untreated hyperadrenocorticism. Therapy with o,p'-DDD resulted in precipitous declines in insulin requirements. By lowering the dosage of o,p'-DDD and supplementing with glucocorticoids during the o,p'-DDD loading period, serious hypoglycemia was avoided. Control of coexisting hyperadrenocorticism lessened the severity of the diabetes mellitus, but insulin therapy remained a necessity in all dogs.

Chloride deficiency signs were produced in young Holstein calves by a low chloride diet (.063% chlorine) and daily removal of chloride in abomasal contents. General clinical signs included anorexia, weights loss, lethargy, mild polydipsia, and mild polyuria. In latter stages of the deficiency, severe eye defects (scleral injection, sunken eyes, scaliness around eyes) and reduced respiration rate became evident. Feces contained varying amounts of blood and mucus. The chloride imbalance resulted in severe alkalosis and hypochloremia leading to secondary hypokalemia, hyponatremia, and azotemia. All deficient calves died after 24, 28, 38, and 46 days of treatment. Chloride concentrations of plasma in each of the calves just prior to death were similar at 31 to 35 meq/liter, which compares with normal 96 meq/liter. One additional calf made chloride deficient was recovered to normal health in 9 days following a single treatment with salt water and feeding of control diet containing .48% chlorine. Control calves fed a diet with .48% chlorine and which also had their abomasal contents removed daily grew normally and exhibited no deficiency signs. When dietary chloride was adequate, removal of abomasal contents (and chlorine) had no adverse effects on the animals.

The case is recounted of a child who was admitted to hospitals several times over a period of 8 years on account of fictitious illnesses invented by his mother. The first occurred when he was 3.5 years old in January 1984. His mother, a nurse, gave a history of intermittent fever for 3 months, loss of appetite and weight. He had been treated with ampicillin, chloramphenicol, and procaine penicillin. No abnormality was detected and his weight at 15.5 kg was appropriate for his age. No fever was recorded throughout 2 weeks in hospital, but he was given chloroquine for possible malaria and then discharged. At follow-up 6 months later, the mother complained of his wheezing. On examination he was normal and had gained 3.8 kg since discharge. The possibility of vernal conjunctivitis plus asthma was entertained and he was then placed on ketotiphen prophylaxis. There was an uneventful follow-up for 6 months. 5 years later in March 1990, his mother related that he had been treated from 22 January 1988 to 21 November 1989 for tuberculosis with streptomycin, isoniazid, rifampicin, and ethambutol. He was also treated with digoxin and Esidrex-K for suspected rheumatic carditis, after which at the University Teaching Hospital, Enugu, he was investigated from 11 April 1989 to 10 August 1989 and found to be normal. One year later in August 1991 she went to one of the authors complaining about polydypsia, polyphagia, and polyuria. Examination had revealed nothing of note. A clinical assessment for diabetes mellitus found the urine specific gravity persistently at 1.010. He was therefore put on carbamazepine (Tegretol) 100 mg t.i.d. After review by a pediatric nephrologist, the child was declared normal. During this visit, the mother and child were interviewed separately. He believed he was ill because his mother said so. A diagnosis of Munchausen syndrome by proxy was made. The mother was referred back to her doctor to arrange for psychiatric care. In Munchausen syndrome, patients fabricate a variety of symptoms and evidence of illness that have no organic basis. Munchausen syndrome by proxy is a form of child abuse, difficult to diagnose, that could result in death. It is more prevalent in affluent countries with sophisticated medical facilities. Its rarity in developing countries may contribute to the difficulty of detection.

Primary hyperparathyroidism is a not uncommon disease in the elderly. A prevalence of 3% for women and 1% for men is reported in subjects aged 65 years and over. Routine serum calcium determination and parathyroid hormone radioimmuno-assay allow to make an early diagnosis in still asymptomatic subjects. In the elderly the clinical features of the disease are often aspecific presenting with psychiatric and/or neuromuscular and/or cardiovascular disorders. This report refers to a 75 year-old woman admitted to our Department with a suspicion of senile dementia. She was affected by loss of memory, hallucinations, nausea, loss of appetite, mild polydipsia and polyuria. The patient was dependent in one activity of daily living (Index of Independence in Activities of Daily Living, ADL) and partially dependent in instrumental activities of daily living (Instrumental Activities of Daily Living Scale, IADL). The Short Portable Mental Status Questionnaire (SPMSQ) and the Geriatric Depression Scale (GDS) showed mild mental impairment and mild depression. Routine biochemical screening revealed a significant hypercalcemia. Parathormon assay and parathyroid scintigram were performed to confirm the diagnosis of primary hyperparathyroidism. After treatment of dehydratation and hypercalcemia, parathyroidectomy was performed: a single parathyroid adenoma was found and removed. On discharge the patient was lucid and able to carry out all ADLs and IADLs.

A six-month-old, female German shepherd dog was presented because of depression, anorexia, vomiting, polyuria, and polydipsia of approximately 10 days' duration. The puppy was depressed, and pain could be elicited on palpation of both shoulders and hips. The most significant results of serum chemistries and hematology were hypercalcemia; increased blood urea nitrogen, creatinine, and alkaline phosphatase; and leukocytosis with neutrophilia. Thoracic radiographs revealed a large thymic mass, diagnosed on histological examination as a thymic lymphoma. Radiographs of the shoulders revealed destructive bone lesions involving the proximal metaphyses of the humeri, causing slipped epiphyses. Bone lesions were found at necropsy on the proximal and distal aspects of both humeri and femurs. Bone resorption was due to local neoplastic infiltration and presumed humoral factors secreted locally and systemically by neoplastic thymic lymphocytes.
