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 56-year old man was admitted to the hospital with malaise, weakness, and fatigue. He was short of breath and had bilateral foot edema. Even though he had been very active a month earlier, he could no longer climb stairs. For the last two weeks, he had had a cough producing green sputum, a "tight feeling" in his chest, polyuria, and polydipsia. He had not had radiating chest pain, palpitations, leg pain or erythema, hemoptysis, diaphoresis, flushing, fever, chills, nausea, vomiting, diarrhea, or a loud snore.

A Persian male cat with a history of lower urinary tract disease was presented because of polydipsia, polyuria, constipation and nasal discharge. Ten weeks before admission, the cat had been treated for lower urinary tract disease by catheterisation and flushing of the bladder. The animal was thin, dehydrated, anaemic and azotaemic. Urine culture revealed Aspergillus species cystitis. Antibodies against Aspergillus nidulans were identified in serum. Fluconazole was administered orally (7.5 mg/kg, q 12 h) for 10 consecutive weeks. The azotaemia was resolved, the kidney concentrating ability was recovered and the cat has remained healthy without similar problems.

We describe a case of a novel mutant vasopressin 2 receptor (V2R)-dependent nephrogenic diabetes insipidus (NDI) with bilateral non-obstructive hydronephrosis in a middle aged man. This could be distinguished from aquaporin 2 (AQP2)-dependent NDI by the response of factor VIII and von Willebrand factor (vWF) to 1-deamino-8-D-arginine vasopressin (DDAVP) administration. A 47-year-old man was admitted to hospital because of polyuria, which had been present from infancy and was suspected of causing non-obstructive hydronephrosis. His mother's father, the older brother of his mother and his second daughter also all had polyuria. Sodium concentration, osmolality and vasopressin in blood were high, while sodium concentration and osmolality in urine were low. There were no changes in urine osmolality, factor VIII and vWF in response to DDAVP infusion. Neither was heart rate, diastolic blood pressure nor facial flushing affected. These findings suggested this case was V2R-dependent NDI rather than AQP2-dependent NDI. Molecular genetic analysis demonstrated that the patient had a V2R missense mutation involving a substitution of cysteine for arginine at position 104 (R104C) located in the first extracellular loop of the V2R. It was also found that the patient's mother and his second daughter were heterozygous for this R104C mutation.
