Decentralized laboratory testing: attitudes of physicians and medical students.

Attitudes regarding the use of decentralized laboratory testing were examined in two groups of district physicians (DP; n = 15), a group of physicians undergoing postgraduate training as specialists in general medicine (PP; n = 17), and a group of medical students who had completed five years of basic studies (MS; n = 15). A sorting test was employed involving 56 cards with names of laboratory tests presently or soon available for use within primary health care. The DPs showed a relatively high consensus concerning which analyses were needed most for near-to-patient testing. MSs (who had a basically hospital-oriented education) differed from DPs and PPs in emphasizing the need for a greater number of directly available tests in primary health care. The differences probably reflect differences in clinical experience. The importance of practically oriented education is stressed.

DDAVP test for renal concentration capacity. Age-related reference intervals.

The effect of different levels of fluid intake on the renal concentration test was evaluated. Maximal urinary osmolality did not significantly differ whether strict fluid restriction was kept or not. One side effect, namely headache, seemed more frequent after fluid deprivation than after a more liberal fluid intake. We suggest a practical approach to the performance of the urinary concentration test with DDAVP. The maximal urinary concentration after a single subcutaneous injection of 4 micrograms DDAVP was determined in 212 healthy adults aged 20 to 80 years. A significant decline with age was found in maximum urinary concentration, mean values ranging from 982 mOsm/kg at 20 years to 823 mOsm/kg at 80 years. References are given for different ages which render the test useful in adult patients.

Subcutaneous and intranasal administration of 1-deamino-8-d-arginine vasopressin in the assessment of renal concentration capacity.

Maximum urine concentration capacity was studied in healthy adults using different routes and doses of administration of 1-deamino-8-d-arginine vasopressin (DDAVP)-desmopressin. Plasma levels of DDAVP showed a dose-dependent increase after the subcutaneous but not after the intranasal administration. The effect on urine osmolality was similar but more prolonged after the subcutaneous as compared to the intranasal route. We conclude that subcutaneous injection is a simple and reliable way of administering DDAVP. A dose of 4 micrograms in adults is optimum diagnostically and it corresponds to 20-40 micrograms administered intranasally.

Cholestasis of pregnancy. Clinical and laboratory studies.

A prospective study was made of clinical symptoms, liver function and pregnancy prognosis in women with cholestasis of pregnancy (CP). We used several positive and negative criteria to allow a clinical definition of CP as itching limited to time of pregnancy with or without laboratory evidence of liver dysfunction. The incidence during 1971-74 was 1.5% (100/6798 women) and lower during 1980-82 (52/5441 = 1.0%). One hundred consecutive pregnant women without itching were used as clinical controls. The incidence of CP showed a distinct seasonal variation, culminating in November. Women with CP had often had itching during previous pregnancies and during use of contraceptive pills and described anamnestically itching in mother and sisters. Laboratory data in CP were compared with reference intervals for healthy pregnant women. Serum enzyme levels were significantly increased for serum alkaline phosphatase, 5-nucleotidase, aspartate aminotransferase and alanine aminotransferase in the second and especially in the third trimester. The enzyme distribution was often markedly skewed to the right, i.e. some patients reacted more than others. Most patients with cholestasis only had itching without pronounced abnormalities in laboratory data. This mild form of CP was associated with a good prognosis for both mother and child.
