background: firoozgar comprehensive stroke center started up as the first organized care unit in the country in 2014; this study was performed to investigate quality indicators such as reduction in mortality, morbidity and hospital stay.   methods: two groups of ischemic stroke patients were compared. the first group had been admitted in general neurology ward (non-stroke unit patients) and the...

In all, 611 patients were admitted to the coronary care unit during the first 16 months. The diagnosis of acute myocardial infarction was confirmed in 461 (73.4%) of these patients and the results of treatment are shown. The hospital mortality was 19.1 per cent. Eighteen patients, who would have died without resuscitation, survived and left hospital. Ventricular fibrillation occurred in 41 (8.9...

OBJECTIVE Clinical practice is an activity accompanied by risks and uncertainties. The objectives are: to determine the incidence of patients with adverse events (AE) in a general surgery unit; to analyse the associated factors; to consider their impact and to identify the prevention possibilities. PATIENTS AND METHOD Ambispective study in patients taken care of in a general surgery unit in a...

Previous work in representing transformational uncertainty used a linearized perturbed-transform method which assumes small angle errors. This paper presents an alternative representation using random unit quaternions that makes no strict small angle error assumption. The approach uses a novel family of probability density functions derived by placing a unit-length constraint upon some or all o...

Four patients with hyperparathyroidism who presented in atypical or uncommon ways to a general medical unit are described. The unusual features are discussed and the value of modern procedures for localization of a parathyroid tumour is confirmed.

We show that if a monopoly sector is imbedded in a general equilibrium framework and profits are taxed at one hundred percent, then unit (specific) taxation and ad valorem taxation are welfare-wise equivalent. This is contrary to all known claims. Journal of Economic Literature Classification Number:H21

One can prove the following propositions: (2) For all real numbers a, b, r such that 0 ¬ r and r ¬ 1 and a ¬ b holds a ¬ (1 − r) · a + r · b and (1 − r) · a + r · b ¬ b. (3) For all real numbers a, b such that a ­ 0 and b > 0 or a > 0 and b ­ 0 holds a + b > 0. (4) For all real numbers a, b such that −1 ¬ a and a ¬ 1 and −1 ¬ b and b ¬ 1 holds a · b ¬ 1. (5) For all real numbers a, b such that ...
