Poliomyelitis is a problem receiving increasing attention in this country. Although this disease is as old as ancient Egypt, its importance has only been recently recognized and before the middle of this century no significant study of the disease had been carried out. Statistical surveys (Paul, Havens and Van Rooyen, 1944; Paul, 1949; Khalil, Ragab and Sakr, 1954; Gilliam, Hemphill and Gerende...

BACKGROUND We attempted to apply the model of effort-reward imbalance (ERI) to school settings in order to measure students' psychosocial stress and analyze its association with self-rated health in adolescents. METHODS A cross-sectional survey was conducted in Kunming, China among 1004 Chinese students (468 boys and 536 girls) in grades 7 through 12, using a 19-item effort-reward imbalance q...

はじめに SIADH(syndrome of inappropriate secretion of ADH)は 低ナ トリウム麺症を主徴とする病態 である.これを非SIADHの 低ナ トリウム血症と比 較した場合,SIADHで は水分摂取の制限が低ナ ト リウム血症 の治療上有 効であ るの に対 と,非 SIADHで は血清ナ トリウム値の正常化 に先だつ て,脱 水や虚脱等,液 きに危険を伴 う副作用を招 く点で,両 者の鑑別診断は臨床上大き な意味をも つものといえる. ,ラ ジナイム ノアッセイによる血中ADHの 測定が可能 となつて,各 種の低ナ トリウム血症に ついて血中ADH濃 度を検討すると, SIADHの み ならず非SIADHにお いて も多 くの症例 で血 中 ADH濃 度の上昇がみ とめられる.非SIADHの 低 ナ トリウム血症の発症や維持に際 とて も,血...

BACKGROUND So far, Siegrist's model of effort-reward imbalance (ERI) has been tested almost exclusively for paid employment. This article reports results on a newly developed questionnaire measuring ERI in unpaid household and family work. METHODS Using data of a population-based sample of 3129 German mothers, logistic regression analyses were performed to test the following three main assump...

HYPONATREMIA is a common fluid and electrolyte disturbance. The decrease in plasma sodium concentration is usually associated with a reduction in body fluid osmolality, a state that causes shifts of water between the interstitium and the cells. This review is addressed to the cellular response of tissues to a reduction in plasma osmolality. We briefly describe the current understanding of how h...

Objectives: The objective was to evaluate the contribution of the combined analysis of psychosocial stress at work and its association with common mental disorders (CMD) among health workers. Methods: A cross-sectional study was conducted on a representative sample of primary care workers from five counties in the state of Bahia, Brazil. The outcome variable - CMD - was assessed by the SRQ-20...

Highly n-doped silicon nanowires (SiNWs) with several lengths have been deposited via chemical vapor deposition on silicon substrate. These nanostructured silicon substrates have been used as electrodes to build symmetrical micro-ultracapacitors. These devices show a quasi-ideal capacitive behavior in organic electrolyte (1 M NEt4BF4 in propylene carbonate). Their capacitance increases with the...

BACKGROUND Amlodipine and hydrochlorothiazide (HCTZ) are commonly prescribed in Nigeria either as a monotherapy or in combination with other drugs. The present study was designed to investigate the antihypertensive efficacy of monotherapy with amlodipine or HCTZ and their effects on electrolyte profile in patients with mild to moderate hypertension. METHODS A single-blind randomized clinical ...

Hypokalemia is a common electrolyte disturbance, especially in hospitalized patients. It can have various causes, including endocrine ones. Sometimes, hypokalemia requires urgent medical attention. The aim of this review is to present updated information regarding: (1) the definition and prevalence of hypokalemia, (2) the physiology of potassium homeostasis, (3) the various causes leading to hy...

Arguments in favor of the importance of non-thermal factors in the control of skin circulation are presented. Such factors include exercise, posture, water and electrolyte balance, state of training, and acclimatization. The first three factors probably elicit their effects via high- and low-pressure baroreceptors, while the mechanisms involved for the remainder are unknown.
