Four hundred and three teenage secondary school students (50.6% males) from two girls' and two boys' Nairobi City Schools, selected by stratified sampling, were screened to determine the prevalence of proteinuria, haematuria, nitrituria and hypertension. Nine students (2.2%) had significant proteinuria while 14 (3.5%) had microscopic haematuria. Two students had ...

The syndrome of congestive heart failure is characterized by activation of many neurohormonal systems with vasoconstrictor and vasodilator actions. Data suggest that the stimulus that evokes this response is a threat to the arterial blood pressure. The long-term consequences of this response on the kidney are retention of sodium and ...

This study reports the use of computer-assisted sensorimotor testing in 75 patients with chronic peripheral nerve compression. Pinch and grip strength, and the cutaneous pressure threshold were measured. The reliability of this equipment for repeated measurements was excellent (r = 0.95). The pressure threshold at which a one-point static stimulus ...

How an increase in blood pressure, in and of itself, induces hypertensive nephrosclerosis is unclear. In an earlier study we found that leukocyte infiltration, proximal tubular cell proliferation, matrix deposition and interstitial fibrosis occur in the unclipped kidney of 2 K 1 C Goldblatt hypertensive rats. In this study we ...

The mouse remains the animal of choice in transgenic experiments, creating a need for methods of evaluating the physiology of genetically modified animals. We have established and characterized two murine models of renovascular hypertension known as the two-kidney, one clip and one-kidney, one clip models. The appropriate size of the ...

Surveys taken of blood pressure in Greenland indicated prevailing levels similar to those in the USA. Morphometrically measured renovasculopathies in 88 autopsies confirmed blood pressure levels comparable to the survey findings. At clinic visits, the recorded blood pressures in 48 of the autopsies verified the morphometric conclusions (r = 0.559). ...

In order to identify a high-risk group for the development of arterial hypertension after extracorporeal shock wave nephrolithotripsy (ESWL), we correlated the increase in renovascular resistance induced by ESWL in 79 normotensive patients with changes in arterial blood pressure occurring 20 (+/- 3) months after therapy. Renal vascular resistance was ...

Probing of the sensitive, soft periodontal tissues differs markedly from probing of the dental hard tissues and caries. Periodontal probing requires special skills as well as an understanding of the tissues being examined, the probing procedure and the use of an appropriately designed instrument. Periodontal probing seeks to complement the ...

BACKGROUND: Nearly 50 million Americans have hypertension, and renovascular hypertension accounts for perhaps 1% of them. PURPOSE: To review the current recommendations and the available screening tests for renovascular hypertension. SUMMARY: The presence of clinical clues increases the predictive value of screening tests for renovascular hypertension; these include abrupt onset ...

We surveyed a random sample of 250 optometrists (OD) and 250 ophthalmologists (MD) in November 1991 to determine if they were involved in blood pressure measurement. A 50.4 percent and 34.8 percent response rate was obtained from ODs and MDs, respectively. Of those responding, 85 percent of the optometrists and ...

In screening subjects for a continuous variable, such as blood pressure (BP), for eligibility for clinical trials, multistage rules are often used to select subjects within a target range. Multiple readings may be taken over successive visits, and the subject must meet eligibility criteria at each visit. We present an ...

This paper reviews blood pressure tracking from childhood through adolescence, to adulthood. Blood pressure tracking correlations in childhood and adolescence vary from 0.2-0.6. Systolic blood pressure tracks better than diastolic pressure. There does not appear to be a gender difference, except that girls mature earlier than boys and so reach ...

Extrusion-spheronization is a popular means of producing spheres which can be coated to form a controlled-release system. In the extrusion process, stress is necessary to force a wet mass through small orifices, and as a result, frictional heat builds up at the screen. Therefore, the quantitative measurement of the screen ...

Alterations in calcium metabolism have been detected in both human and rat primary hypertension at various levels of the biological organization; in particular, an abnormal renal electrolyte handling, leading to chronically enhanced urinary calcium excretion, has been demonstrated. In keeping with this finding, a significant statistical association between high blood ...

Anabolic steroids have been employed extensively in equine practice over the past 25 years. Their usefulness is largely dependent on subjective opinions, as only minimal studies have been carried out in horses. Therefore, their use will vary markedly between practitioners depending on their personal experiences and pressures by trainers to ...

Multistage blood pressure screening rules are often used to select subjects for clinical trials. Multiple blood pressure readings are taken over successive visits, and the subject must meet eligibility criteria at each visit. In this paper, the authors present methods which depend on the distribution of the subject's underlying blood ...

Screening for hypertension within the proper setting potentially leads to the detection of numerous (mild) hypertensives, some of whom in due time may well qualify for treatment. One disadvantage of the procedure appears to be that hitherto unwitting hypertensives may develop some adverse psychological and physiological phenomena. Behavioral effects seem ...
Townsend R R - - 1993
The clinical laboratory is essential to the successful and complete evaluation of the patient with hypertension. A reasonably thorough knowledge of the important physiologic components of blood pressure regulation, in conjunction with a good history and physical examination and a simple panel of screening tests serve to detect or rule ...
