In a serological survey among Dutch patients suspected of leptospirosis, using a recently developed enzyme-linked immunosorbent assay, a patient was traced with a high antibody titre to Hantaan virus. No anti-leptospira antibodies were detected in this 27-year-old man. Shortly before he had been admitted to the hospital with progressive dyspnoea and coughing, accompanied with high fever. An interstitial pneumonia was diagnosed. He subsequently developed a progressive renal failure with proteinuria and polyuria. Later a liver failure accompanied with thrombocytopenia, anaemia and coagulation disturbances occurred. Before an aetiological diagnosis was made, the patient was treated with erythromycin. The patient eventually recovered completely. Based on the clinical symptoms and the positive serology, it was concluded that the disease diagnosed had probably been caused by a Hantaan virus infection. The diagnostic value of Hantaan virus serology in patients with similar symptoms is stressed.

Hyperadrenocorticism was diagnosed in 7 cats with concurrent diabetes mellitus. Four cats had pituitary adenoma with bilateral adrenocortical hyperplasia, 1 cat had pituitary carcinoma with bilateral adrenocortical hyperplasia, 1 cat had adrenocortical carcinoma, and 1 cat had adrenocortical adenoma of the left adrenal gland. One year later, adrenocortical adenoma involving the right adrenal gland also was diagnosed in this cat. Clinical signs included polyuria and polydipsia (n = 7), development of pot-bellied appearance (n = 5), dermatologic alterations (n = 5), lethargy (n = 3), weight loss (n = 3), dyspnea/panting (n = 2), and recurrent bacterial infections (n = 2). In 6 cats, the diagnosis of hyperadrenocorticism was established before death on the basis of results of the ACTH stimulation test (n = 3) and the dexamethasone screening test (n = 5). Pituitary-dependent hyperadrenocorticism was differentiated from adrenocortical neoplasia on the basis of results of the dexamethasone suppression test (n = 4), endogenous ACTH concentration (n = 3), results of abdominal radiography and ultrasonography (n = 3), and exploratory celiotomy (n = 1). Four cats died or were euthanatized without treatment attempts. Treatment with mitotane followed by 60Co teletherapy was ineffective in one cat with pituitary adenoma. One cat with pituitary carcinoma died one week after bilateral adrenalectomy. Bilateral adrenocortical adenomas were removed surgically in the affected cat.

Radioactive iodine (131I) was used in the treatment of a 12-year-old female dog with hyperthyroidism resulting from a large, unresectable (and metastatic) thyroid carcinoma associated with signs of severe inspiratory stridor and dyspnea. Hyperthyroidism was diagnosed on the basis of clinical signs (polyuria, polydipsia, polyphagia, weight loss, nervousness) and high basal serum thyroxine (T4) concentrations, as well as thyroid radioiodine kinetic studies that showed a high radioiodine uptake into the thyroid (% thyroid uptake) and markedly increased serum concentrations of protein-bound iodine-131 (PB131I) after 131I tracer injection. Thyroid imaging revealed diffuse radionuclide accumulation by the tumor, which involved both thyroid lobes. The dog was treated with three large doses of radioiodine (131I), ranging from 60 to 75 mCi, given at intervals of 5 to 7 months. The dog became euthyroid, and the size of the tumor decreased by approximately 25% after each 131I treatment, improving the severe inspiratory stridor and dyspnea, but both the hyperthyroid state and breathing difficulty recurred within a few months of each treatment. The dog was euthanatized 5 months after the last treatment because of progressive tracheal compression and pulmonary metastasis.

The combination of nifedipine and atenolol must be evaluated in terms of risks and benefits to the hypertensive patient. Disadvantages with single-agent therapy justify trials of combination regimens. beta-Blockers may be unacceptable to some patients because of gastrointestinal upset, musculoskeletal symptoms, tiredness, malaise, insomnia, depression or confusion, sweating, breathlessness or cold extremities. The side effect profile varies from patient to patient and between different beta-blockers. Calcium antagonists also have characteristic side effects, including severe headaches, flushing and oedema, tachycardia and possibly worrying palpitations, and polyuria. Combining a calcium antagonist and a beta-blocker can reduce some side effects; for example, tachycardia is offset by addition of beta-blocker to calcium antagonist therapy, and beta-blocker-induced cold extremities may be reversed with a drug such as nifedipine. Moreover, the antihypertensive efficacy is increased, which is useful in previously resistant patients. However, an excessive fall in blood pressure is a possible adverse effect of the combination. There is also the possibility of precipitating heart failure in patients with cardiomegaly and severely compromised left ventricular function. The combination of nifedipine and atenolol was evaluated in 25 patients in a randomised, crossover trial following a month's treatment with atenolol 50mg twice daily. Patients received either atenolol 50mg twice daily alone, or atenolol 50mg twice daily with sustained release nifedipine 20mg or 40mg twice daily, or placebo twice daily during three 4-week treatment periods. Additional antihypertensive benefit was obtained by addition of the low dose of nifedipine compared with atenolol alone, but no further advantage was obtained with the higher nifedipine dose.(ABSTRACT TRUNCATED AT 400 WORDS)

A 21-year-old female was admitted to Tamono City Hospital with chief complaint of dyspnea due to spontaneous pneumothorax. The patient was transferred to our clinic for further examination of abnormal chest X-ray findings together with skin lesions and other symptoms of polyuria, amenorrhea and narrowed visual fields. Histochemical and electron microscopic examination of lung tissue obtained by open lung biopsy led to the diagnosis of eosinophilic granuloma. Furthermore, enhanced computed tomography and magnetic resonance images showed the existence of an intracranial tumor in the supra-hypophyseal region which was interpreted as the cause of hormonal and visual disturbances. Because of dyspnea and enlargement of intracranial tumor, treatment with steroid hormone was commerced followed by tapering of the dose. Chest X-ray findings and skin lesions improved markedly and the intracranial tumor regressed significantly with this steroid therapy, indicating that the intracranial tumor represented involvement with eosinophilic granuloma.

Oil-containing triaryl phosphates induced delayed organophosphate neurotoxicosis in 4 dairy heifers. Clinical signs developed 10 to 14 days after exposure and included dyspnea, dysuria, polyuria, tympanites, incoordination, hind limb weakness with knuckling of the metatarsophalangeal joints, and flaccid paralysis. Triaryl phosphate concentrations were high in a specimen of fat from 1 heifer, and the fat and 2 waste oil samples used to periodically lubricate a feed bunk motor chain had similar triaryl phosphate-like chromatographic profiles. The diagnosis of delayed organophosphate neurotoxicosis requires history of exposure to a potential toxicant, appropriate histologic evaluation of the CNS and, ideally, identification of the toxic agent from appropriately selected animal tissues.

Migraine headache and panic disorder are two conditions that have a number of underlying physiological and psychological abnormalities in common. The temporal relationship between the occurrence of migraine headache and panic attacks could be different, however. According to our observations, some migraine subjects develop panic attacks with the typical symptoms (palpitation, dyspnea, anxiety/fear, shiver, sweating, polyuria) on the "peak" of their attacks. This variant of migraine without aura was conditionally defined as "panic migraine". Here we describe two patients suffering from migraine without aura in whom migraine was associated with the typical panic attack. It is suggested that a pronounced autonomic dysregulation along with marked psychological abnormalities could be responsible for the constellation of migraine and panic symptoms during one episode. Taking into account the previously obtained results, it is concluded that compared to "pure" migraine, "migraine associated with panic attacks" is characterized by a severe course, marked autonomic and emotional disturbances during pain-free intervals, seriously impaired quality of life, and requires a specific therapeutic approach.

Ramaria flavo-brunnescens collected in autumn from 1990 to 1994 was orally administered to 11 sheep. These animals were dosed with 100-430 g/kg bw administered over 3-13 d. Six sheep showed clinical signs and 4 of them died. The mininum toxic dose was of 150 g/kg bw. Clinical signs were anorexia, hyperthermia, dyspnea, polyuria, ataxy, muscle tremors and seizures. The eyes had hyperemia of the sclera and, in some cases, hemorrhages of the anterior chamber or corneal opacity. Sheep dosed with higher doses had ulcerations of the tongue and necrotic lesions in the hooves. The main histologic lesions of the feet and tongue were miopachynsis and endotelial degeneration followed by degeneration, necrosis and ulceration of the epithelium. Hemorrhages of the anterior chamber, and severe congestion and hemorrhages of the iris, ciliary body and process were observed in the eyes. Congestion and perivascular hemorrhages occurred in the central nervous system. The similarity of clinical signs and pathologic lesions induced by R flavo-brunnescens and those caused by ergotism in cattle and sheep suggests the presence ofa vasoactive constrictive substance in the mushroom. Fresh R flavo-brunnescens dosed in autumn 1993 was not toxic at doses of 200-400 g/kg demonstrating variations in the toxicity of the mushroom from year to year.

Over 650 pigs died within a couple hours in a fattening unit with approximately 3,000 fattening spaces. The pigs showed vomiting, dyspnea, kyphosis, sunken flanks, diarrhea, and polyuria. Another striking symptom of the pigs, besides the apathy, was the aphonia, due to the calcification of the vocal cords. An acute vitamin D3-intoxication was found to be the cause. The pathologic findings, especially the histologic detection of calcification processes of the soft tissues, lead to the suspect of an intoxication with a vitamin D-like substance. Between 39,000 and 196,000 IU/kg of vitamin D3 have been detected in a ready-to-use food mix. 8.8 million IU/kg of crystaline vitamin D3 were found in an open whey bag. An explanation how vitamin D came into the bag could not be clarified to this point.
