BACKGROUND: Stroke incidence and case-fatality are reported to decline in high-income countries during the last decades. Epidemiological studies are important for health services to organize prevention and treatment strategies. AIMS: The aim of this population-based study was to determine temporal trends of stroke incidence and case-fatality rates of first-ever stroke in Arcadia, a prefecture in southern Greece. METHODS: All first-ever stroke cases in the Arcadia prefecture were ascertained using the same standard criteria and multiple overlapping sources in three study periods: from November 1993 to October 1995; 2004; and 2015-2016...

OBJECTIVE: To investigate the prevalence of intracerebral hemorrhage (ICH) using stroke database from the main tertiary hospital in Qatar (Hamad General Hospital) over the period of Dec 2013 to Oct 2017. METHODS: The prevalence of ICH was calculated based on age groups and ethnicity (Qatari nationals, non-Qatari Arab, South east Indian (SI) and Far East Asians (FE)). Thirty-day case fatality rate, poor clinical outcome at discharge (modified Rankin scale (mRS):3-6) and poor long-term outcome (mRS at 90 days: 3-6) were calculated per each age group sex and ethnicity...

As an underdeveloped country, the coronavirus disease 2019 (COVID-19) epidemic has posed a major risk to the health and economy of Pakistan. The SIR (susceptible-infected-recovered) model of epidemiologic analysis predicts that there should have been more cases since late March 2020 in Pakistan. We therefore sought to investigate COVID-19's prevalence and epidemiologic trends in Pakistan. Research for COVID-19 is still in its early stages, so data were collected from official websites and research journals, then analyzed for the disease's prevalence, epidemiology, mortality and recoveries...

Painful diseases of the pelvis are not rare. Urethral and scrotal pains are part of the chronic pelvic pain syndromes along with chronic prostatitis and painful bladder syndrome/interstitial cystitis. The objective of this review is to update the current knowledge about epidimiology, etiology, diagnosis and best treatment for patients with urethral and scrotal pain syndromes. Epidemiological data for both syndromes are scant. We lack of uniform definition or readily available diagnostic marker and aetiology remains unclear...

HTLV-I is a retrovirus known as an oncogenic virus for human. This virus, initially found as a causative agent for adult T cell leukemia, has been lately focused as a causative virus for several autoimmune disorders. Here we described the characteristics of polyarthritis in HTLV-I careers, which is indistinguishable from idiopathic rheumatoid arthritis (RA). The relationship between arthritis and this virus was clearly proved by epidimiological study. Moreover, we presented transactivating gene of this virus, tax, is responsible for proliferation of synovial cells...

An improved method of analysis has been devised for estimating the amount of hydroxyproline excreted into the urine. This study has been performed to overcome the difficulties accompaning mass-examinations which are indispensable in epidimiological studies. Urine samples are pretreated with a resin-charcoal mixture for elimination of interfering substances or color inhibitions, and the supernatant is treated by evaporation to avoid complications followed by pH adjustment. The residue is reconstituted with diluted HCL...

On the thigh of an Europa Beaver, Castor fiber L., dead after 8 years of captivity, a candidiasis has been found due to Candida albicans. Were reported successively: the frequence of C. albicans in the Europa Beaver and the Canada Beaver, the diagnosis, an epidemiologic aspect and the morphologic parasitic form of that yeast. In the epiderma parasited of the Beaver, C. albicans has developed in a yeast-form in the superficial strates of the skin and in the filamentous-form in the deeper.
