Background : Left main coronary artery (LMCA) disease represents important and serious portion of coronary artery disease(CAD).
Aim: The aim of this study is to estimate the incidence of LMCA disease among patients with CAD undergoing coronary artery angiography and to evaluate clinical characteristics of patients with LMCA disease.
Methods: The study involved review of clinical notes and coronary angiography of 1020 patients with CAD in Ibin Al Bitar hospital for cardiac surgery between April and September 2004.This review included evaluation of electrocardiogram (ECG), echocardiogram(ECHO), ECG exercise test (EET) and coronary angiography.
Results: Among 56 patients proved to have left main coronary artery (LMCA) disease,40 patients had complete data available which were studied. Mean age of patients with LMCA disease was 60 ± 8.07 years, 82% of them were males, 62% were smokers, 40% were diabetics and 55% were hypertensive. In this group 62.5% of patients with LMCA disease presented as acute coronary syndrome (ACS) and 37.5% as chronic stable angina (CSA),normal left ventricular (LV) function was found in 75% of patients and 40% have normal electrocardiogram (ECG).
Patients with LMCA disease who have distal involvement represent 75%,15% have diffusely diseased LMCA, right coronary artery (RCA) was involved in 80% of patients and those with
RCA involvement were more commonly presented with ACS (78%), while those without RCA involvement presented more as CSA. Those patients who underwent ECG exercise test had poor functional Capacity, with mean exercise duration of 3.7 ± 2.3 minutes and mean metabolic equivalents (METs) of 4.5 ± 2.46. The tests were positive in 76.9% of patients inconclusive in the rest but no negative tests were recorded. No significant differences were observed between those patients with ACS and those with CSA in regard to patients' characteristics.
Conclusion: LMCA disease is not uncommon among those with CAD, it occurs in patients with multiple cardiovascular risk factors. Patients with LMCA disease usually have poor functional
capacity and their ETTs are commonly positive and of high risk score. Involvements of right coronary artery (RCA) in addition to LMCA render the patients more unstable.
Background: Tuberculosis infection represents a global health problem and a great risk to Health Care Workers. Identifying individuals, particularly Health Care Workers with latent tuberculosis infection will support tuberculosis control through chemoprophylaxis and prevent cross-infection. The aim of this study was to assess the prevalence and some risk factors for latent tuberculosis infection among Health Care Workers in three tuberculosis health institutions in Baghdad.
Methods: A cross-sectional study was conducted in 2013 in Baghdad- Iraq on Health Care Workers working in the Specialized Respiratory & Chest Diseases Center (Tuberculosis institute), Ibn Zuhur Hospital for Chest Diseases and
Background: Implant stability is considered one of the most important factors affecting healing and successful osseointegration of dental implants. The aims of the study were to measure the implant stability quotient (ISQ) values during the healing period and to determine the factors that affect implant stability. Materials and methods: Thirty patients enrolled in the study (17 female, 13 male). They received 44 Implantium® Dental Implants located as the following: 22 implants in maxillary jaw, 22 implants in mandibular jaw from them 17 implants in anterior segment and 27 in posterior segment. The bone density determined using interactive CT scan and classified according to the Misch bone density classification (29 implants in (D3), 15 i

A disinfection technique must be practical and devoid of damaging effects on the material's properties used to construct the denture base. The main aim of this study is to evaluate the effect of three concentrations of electrolyzed water denture cleanser on heat cure acrylic and polyamide after immersion in electrolyzed water. The evaluation is based on their efficacy on surface hardness, wettability, and color stability compared with one submerged in distilled water as a control group. The method consists of eighty samples of heat-cured acrylic and polyamide material.

health nursing.
Methodology: A descriptive study was conducted on non probability sample (purposive) of (175) students' in
Nursing College/ University of Baghdad for the period of June 19th to July 18th 2013. A questionnaire was used as a
tool of data collection to fulfill with objective of the study and consisted of three parts, including demographic,
clinical learning environment and clinical training for students' in maternal and child health nursing. Descriptive
statistical analyses were used to analyze the data.
Results: The results of the study revealed that the 65.1% of student at age which ranged b
This review discusses the gingival biotypes, their characteristics, analysis based on the measurement of the dentopapillary complex. Also discuss their response to inflammation, surgery, and ridge healing after tooth extraction, their influence in the behavior of the peri-implant tissue
Background: Chronic periodontitis is an inflammatory disease of tissues supporting the teeth. Salivary compositions have been most intensely studied as a potential marker for periodontal disease. In this study, analysis of saliva provides a simple and non-invasive method of evaluating the role of salivary IgA (s-IgA) levels in periodontal disease by detecting the level of (s-IgA) in patients with chronic periodontitis smokers and non smokers patients and correlate the mean (s-IgA) levels with clinical periodontal parameters Plaque index (PLI) gingival index (GI), probing pocket depth (PPD) and clinical attachment level (CAL). Materials and Methods: The study samples consists of (15) patients with chronic periodontitis who were non smokers (

Objectives: The objectives of the current study were to determine the overall health literacy level among diabetic patients attending the PHC centers and to test the association between the measured health literacy and their glycemic control.
Methods: A cross-sectional study was conducted on a sample of randomly selected diab

Risperidone rebalances dopamine and serotonin to improve thinking, mood, and behavior by working on dopamine and serotonin α2receptor antagonism. Risperidone has poor solubility and high permeability through the intestine, so it belongs to Biopharmaceutical Classification System (BCS) class II exhibits poor oral biopharmaceutical properties.
The aim of the present work was to improve solubility and dissolution of Risperidone by preparing nanosuspension using different stabilizers and different solvents in a method known as solvent-antisolvent precipitation method. Twenty-eight formulas were prepared
