We assessed the use and determinants of cardiac catheterization during index admissions, among patients with acute coronary syndrome (ACS) in the Middle East. Data were analyzed from 8150 consecutive ACS patients enrolled prospectively. The overall rate of cardiac catheterization was 20%. Major predictors of cardiac catheterization were university hospitals, hospitals with catheterization facilities, physician type, and Gulf citizenship. High-risk patients were catheterized less compared to low-risk patients; odds ratio (OR) 0.44, 95% confidence interval (CI): 0.33-0.60, P < .001 and OR 0.68, 95% CI: 0.48-0.98, P = .037 for patients with non-ST-elevation ACS and ST-elevation myocardial infarction, respectively. The use of cardiac catheterization in patients with ACS from Middle East is low. It is related more to hospital characteristics than to baseline risks. There is a need to explore ways to increase overall rate of in-hospital cardiac catheterization in the region and direct it to patients who would benefit most. Source

Carcinoid tumors are relatively rare and can occur in the thorax, abdomen, or pelvis. Functional imaging in the form of Indium-111 pentetreotide scanning is widely used for identification of these tumors and it exploits the fact that the vast majority of these tumors express somatostatin receptors on their cell membrane. In this report, we present a case of a 76-year-old man who was diagnosed with peritoneal carcinomatosis. The findings of the initial imaging made by planar and single photon emission computed tomography were misleading and the actual diagnosis was only made by single photon emission computed tomography/computed tomography. © OMSB, 2014.

The primary concern in patients with bifascicular block is the increased risk of progression to complete heart block. Further, an additional first-degree A-V block in patients with bifascicular block or LBBB might increase the risk of block progression. Anesthesia, monitoring and surgical techniques can induce conduction defects and bradyarrhythmias in patients with pre-existing bundle branch block. In the setting of an acute MI, several different types of conduction disturbance may become manifest and complete heart block occurs usually in patients with acute myocardial infarction more commonly if there is pre-existing or new bundle branch block. The question that arises is whether it is necessary to insert a temporary pacing catheter in patients with bifascicular block undergoing anesthesia. It is important that an anesthesiologist should be aware of the indications for temporary cardiac pacing as well as the current recommendations for permanent pacing in patients with chronic bifascicular and trifascicular block. This article also highlights the recent guidelines for temporary transvenous pacing in the setting of acute MI and the different pacing modalities that are available for an anesthesiologist. Source

Twenty-two carbapenem-resistant enterobacterial isolates were recovered from patients hospitalized between October 2010 and March 2011 at the Royal Hospital of Muscat, Sultanate of Oman. Eleven NDM-1, five OXA-48 and one NDM-1 plus OXA-181 producers of diverse ST types were recovered from clinical samples. All carbapenemase genes were located on self-conjugative plasmids and were nearly always associated with other resistance determinants, including extended-spectrum β-lactamases and the ArmA methylase encoding resistance to aminoglycosides. This work highlights the dissemination of NDM-1 and OXA-48-type producers in the Middle East. © 2012 European Society of Clinical Microbiology and Infectious Diseases. Source

Although coronary heart disease is the leading cause of morbidity and mortality in the Middle East (ME), not much is known about patients with ST-segment elevation myocardial infarction (STEMI) from this region. The STEMI Chain of Survival can be used to target regional improvements in patient care. We tried to adopt a modified chain of survival for STEMI to highlight the challenges and difficulties and the possible solutions to improve the STEMI care in the Middle East based on the few data available.
