To document the types of imaging modalities that are commonly prescribed during dental implant therapy in South Africa. The radiographic preferences were obtained from practitioners via an electronic survey that was disseminated during local dental conferences, electronic channels (e.g., email lists) of multiple dental schools and local dental scientific societies, and personal interviews. The survey consisted of multiple-choice questions which were designed to investigate the most common radiographic prescriptions during various treatment phases of implant therapy. The responses of one hundred and forty-two participants (General practitioners and dental specialists) practising in different South African provinces were collected and assessed. Principally, panoramic radiographs combined with cone beam computed tomography (PAN + CBCT) followed by CBCT, as a single examination (ASE), were the most preferable modalities during the implant planning phase (39% and 29%, respectively). During and directly after the surgery, periapical radiographs (ASE) were the most preferred (87% and 65%, respectively). The most widely preferred radiographic examination during the planning of implants was panoramic radiographs combined with CBCT. Periapical radiographs (ASE) were favoured during, directly after the treatment, and during the follow-up of asymptomatic patients by the majority of participants. However, CBCT (ASE) was preferred in the follow up of symptomatic patients. Factors related to extra anatomical information and superior dimensional accuracy provided by three-dimensional volumes (e.g., CBCT volumes), were the most indicated influencing factors on the radiographic prescriptions during implant planning.

Background: The incidence of arrhythmic complications in Egyptian patients with acute coronary syndromes (ACS) has not been previously reported. The present study results will serve as the local database for future studies. Aim: To evaluate the incidence of arrhythmic complications in ASC among Egyptian patients and to identify factors that may affect arrhythmia complications in ACS patients. Material and Method: Data collected from 400 patients admitted to cardiology department of Suez Canal University Hospital from 1 January 2009 to 31 December 2011, who were diagnosed as having acute coronary syndrome. This registry includes patients who presented with ACS including ST elevation myocardial infarction (STEMI), non-ST elevation myocardial infarction (NSTEMI) and unstable angina (UA). Results: The study showed that the majority of patients (79.3%) were males of mean age 54.5+10 years, and 70.9% were STEMI. The highest morbidity and mortality were noticed in those of STEMI 25.6% for morbidity and 4.4% for mortality , and those of anterior myocardial involvement 77.7 for morbidity and 56% for mortality. Arrhythmia was present in 74.6% of study population, 57.6% of them were tachyarrythmia, while 26.4% were bradyarrhytmia. The incidence of VT was higher in the younger age group, while AV block and arrhythmic death were higher in the older aged patients. The incidence of different types of arrhythmia was as follows: PVC (39.5%), PAE (19.5%), AF (16.8%), HB (10.1%), VT (9.6%), arrest (asystole) (8.5%), VF (8.1%), RBBB (6.3%), LBBB (4.3%) and Nodal rhythm (3.1%). Our demographic characteristics, risk factors for both ACS and those who had arrhythmias were the same. The patients were younger, smokers, suffering mainly of hypertension, they were more prone to arrhythmias incidence, because they were smokers, mostly STEMI, and of anterior myocardial involvement. Conclusion: Arrhythmias complicating ACS are associated with higher in-hospital mortality. This study showed that the current management strategy is so adherent to guidelines, but deficient for proper arrhythmias management.

Aim: Polymorphisms in apolipoprotein A5 gene (APOA5) have been associated with higher triglyceride levels in many populations. The aim of this study was to determine the distribution of alleles and genotypes of the apoA5-1131T>C polymorphism, as well as to show the association of the genetic variant and the risk for the development of dyslipidemia among Egyptians. Patients and Methods: One hundred and fifty patients with dyslipidemia were included in this study. Additional 150 subjects without dyslipidemia served as a control group. ApoA5-1131T>C polymorphism was determined using PCR-RFLP technique. The total cholesterol, triglycerides, and HDL-c were determined enzymatically. Comparison of means among groups was calculated by ANOVA. Significant differences among groups were evaluated by Student-Newman-Keuls test. Results: The polymorphic allele C was found to be more frequent among subjects with dyslipidemia than control (p=0.019). It imparts an additional individual risk factor for dyslipidemia (OR=1.7, 95% IC=1.09-2.72). The polymorphic allele C was more frequent among dyslipidemic males (OR=2.1, 95% IC=1.04-4.02, p=0.037). Subjects carried the polymorphic allele C (genotypes TC/ CC) showed higher cholesterol and triglycerides levels than subjects with genotype TT (p=0.042 and 0.041 respectively). Conclusion: There is a strong association between ApoA5-1131T>C and dyslipidemia. This association is more obvious among males.
