For calendar years 1993-94, 1999, 2005, 2010, and 2015 we will identify every hospitalized or autopsied stroke and transient ischemic attack (TIA) at all regional hospitals in our region. We will also estimate the number of non-hospitalized strokes and TIAs by screening for potential cases at more

Rationale Bronchoscopy is one of the most important procedures in diagnosis of lung cancer and other pulmonary diseases. This procedures renders important anatomical information and subtle changes in the epithelium or vascularity of the bronchial tree are clues to guide the endoscopist in this

Study population: Consecutive adult patients, age 40 or above, undergoing outpatient colonoscopy in the Queen Mary Hospital are invited to participate in this prospective randomized study. Patients are excluded if they are unable to provide informed consent or have undergone previous colorectal

The aim of this study is that evaluate the remineralizing and antibacterial effects of the different remineralization agents. Initiative caries lesions named as white spot lesions and these lesions are localized at enamel. Demineralization is occured but cavitations aren't seen at this stage. It is

Neurocognitive sequelae observed in preterm represent a major health problem for which there is no preventive treatment approved to date. These effects are the result of a multifactorial brain damage occurring in developing prenatal and perinatal period. Melatonin, the principal hormone secreted by

Urothelial carcinoma of the bladder is the 2nd most common urological malignancy. The vast majority of newly diagnosed cases are non-muscle invasive bladder cancers (NMIBC), which represent about 75%, and it can be treated with transurethral resection (TURBT). The goal of TURBT in Ta and T1 NMIBC is

Study Summary: Title: A Randomized Single-blinded, Prospective Study to compare a Maquet PWD 50SF theatre-light as a light source with natural daylight for the application of photodynamic therapy (PDT) to treat actinic keratoses. Photodynamic therapy (PDT) is of proven efficacy for treatment of

After volunteers and family members agree to participate, they are seen in the Outpatient Research Center by the Principal Investigator or another physician. A detailed history is obtained, a physical examination is performed, and blood is obtained for further tests. Occasionally patients and family

Rationale: Linked Color Imaging is a push-button endoscopic imaging technique developed to enhance the visibility of the vasculature and architecture of the mucosal surface by narrowing the spectrum of absorbed light. Compared to High-Definition White Light Endoscopy, mucosal surface patterns are

From January through June 2019, participants will be requested to attend one of six sessions that will be held at the hospital simulation center. Participants will be randomized into 1 of 2 study arms. Each participant that enters the B-Con course will be randomized using a "random generator." At

Hypertensive intracerebral hemorrhage (HICH) is a type of stroke that is caused by hypertension-induced intracranial arterial, venous, and capillary ruptures. In recent years, the incidence of HICH has become higher, which has exposed society greatly to heavy social and economic burdens. Therefore

The proposed research builds on the most robust, statistically significant and replicated association identified to determine the mechanism by which it may relate to intracerebral hemorrhage (ICH) risk. Given that ICH is an extreme phenotype on a spectrum of manifestations of cerebral small vessel
