Inter-Coronary Communication: A Rare Anomaly in Unusual Site  [PDF]
Husain Jabbad
World Journal of Cardiovascular Diseases (WJCD) , 2015, DOI: 10.4236/wjcd.2015.511037
Abstract: Intercoronary connection is a rare variant of coronary anomalies with a direct continuity between two main coronary arteries. It may function as an alternative pathway to blood flow in compromised coronary circulation. 64 years old male presented with 4 weeks history of retro-sternal chest pain and shortness of breath; his risk factors were diabetes mellitus, hypertension and smoking. Physical examination was normal and he had no audible murmur; he had elevated cardiac enzymes; in echocardiography there was inferior wall hypokinesia, cardiac catheterization revealed complete occlusion of med right coronary artery and complete occlusion of the left main (LM) trunk. Blood flow to the entire myocardium came from large abnormal coronary connection between the right coronary artery ostium and the proximal left anterior descending artery. A smaller arterial communication maintained blood flow to the distal right coronary artery. Cardiac computed tomographic angiography confirmed the presence of a patent left main ostium followed by complete occlusion. This unusual anatomical variation has saved the life of the patient and allowed time for surgical revascularization. The patient underwent successful triple coronary artery bypass grafts with no postoperative difficulties or complications. On one-year follow-up, the patient is asymptomatic, fully active with no new ECG or echocardiography changes.
Surgical Management of Coronary Arteriovenous Fistula in Patients Presenting with Acute Coronary Syndrome—A Local University Hospital 6 Years Experience  [PDF]
Husain Jabbad
World Journal of Cardiovascular Surgery (WJCS) , 2015, DOI: 10.4236/wjcs.2015.512019
Abstract: Background: Anomalies of the coronary arteries are uncommon, usually discovered incidentally during diagnostic cardiac catheterization or cardiac computed tomography (CCT). Coronary artery fistula (CAF) is one of the varieties of coronary termination anomalies. Some of CAF patients have symptoms of myocardial ischemia. Methods: In King Abdulaziz university hospital (KAUH) over six years period, five patients presented with acute coronary syndrome (ACS) and were diagnosed to have CAF by cardiac catheterization during the diagnostic workup of ischemic heart disease (IHD), four males and one female, mean age 57.4 ± 6.6 years; four patients had CAF with associated coronary atherosclerotic disease (CAD); one patient had large complex CAF with no significant CAD; all patients with CAD underwent closure/excision of the CAF with surgical revascularization; the patient with no CAD preferred surgical excision over endovascular intervention. Results: All patients had surgery with uneventful postoperative course and they were doing well with 3 to 7 years outpatient follow up. Conclusion: Surgical management is safe in patients with coronary artery anomalies presenting with ACS.

World Journal of Cardiovascular Surgery (WJCS) , 2014, DOI: 10.4236/wjcs.2014.412035
Abstract: Background: Functional tricuspid regurgitation is a challenge regarding indications for repair and proper surgical technique. Aim of the study: We reviewed our midterm results of tricuspid valve repair for functional regurgitation comparing pericardial strip versus ring annuloplasties. Patients and methods: From January 2008 to December 2013, we operated 59 patients (male:female, 41:18, with a mean age of 34 ± 14 years) for functional tricuspid regurgitation. Tricuspid annuloplasty was done using pericardial strip in 39 patients and ring in 20 patients. Concomitant procedures were mitral valve replacement in 66% of patients, aortic valve replacement in 5% and double valve replacement in 29%. Clinical and echocardiographic data were collected. Results: Preoperative characteristics of the two groups were similar regarding age, percentage of female patients, New York Heart Association functional class and pulmonary artery pressure. More patients with preoperative right ventricular dysfunction were found in pericardial annuloplasty group although this was not statistically significant (13 versus 5; P = 0.52). Operative times were similar in both groups. We had one mortality case (1.69%) due to low cardiac output in the pericardial group. Postoperative complications included reexploration for bleeding in one patient and chronic heart failure in another patient. The average follow up period was 3 years and it was complete in 100% of patients. Postoperative freedom from recurrent moderate tricuspid regurgitation was 90% in both groups. Conclusion: Pericardial strip annuloplasty is a simple, inexpensive, reproducible and efficient technique that has comparable results to ring annuloplasty.
Interprofessional Education as a Need: The Perception of Medical, Nursing Students and Graduates of Medical College at King Abdulaziz University  [PDF]

Abstract: Interprofessional education (IPE) is when members or students of two or more professions learn from and about each other to improve collaboration and quality of care. The aim of this study was to identify the awareness and importance of IPE among medical and nursing students and graduates at King Abdulaziz University. A cross-sectional study was conducted with fourth-year medical students, fourth-year nursing students, interns, and internal medical residents at King Abdulaziz University and hospital. A survey was completed by all the participants after they gave their consent. Participants were asked whether they knew the meaning of IPE. We explained IPE to those who did not know what it was. Then, each participant was asked to rate all 11 items on the survey with one of five choices: strongly agree, agree, undecided, disagree and strongly disagree. A total of 105 professionals participated in the study. The participants were primarily fourth-year medical and nursing students, all of whom were women. However, for the medical interns and medical residents, we included both men and women. Only 12 (11.4%) participants knew the meaning of IPE, all of whom were medical residents. The majority—77 of 103 (75%), most of whom were nursing students—responded that IPE is important. The difference between the groups was also significant (P = 0.008). In conclusion: Our study showed that our medical students and graduates valued IPE and thought that the implementation of IPE in their education would improve both patient care and health care provider satisfaction.
Second-Order Duality for Continuous Programming Containing Support Functions  [PDF]
Iqbal Husain, Mashoob Masoodi
Applied Mathematics (AM) , 2010, DOI: 10.4236/am.2010.16071
Abstract: A second-order dual problem is formulated for a class of continuous programming problem in which both objective and constrained functions contain support functions, hence it is nondifferentiable. Under second-order invexity and second-order pseudoinvexity, weak, strong and converse duality theorems are established for this pair of dual problems. Special cases are deduced and a pair of dual continuous problems with natural boundary values is constructed. A close relationship between duality results of our problems and those of the corresponding (static) nonlinear programming problem with support functions is briefly outlined.

Iqbal. Husain, Rumana. G. Mattoo
Communications and Network (CN) , 2010, DOI: 10.4236/cn.2010.22021
Abstract: A multiobjective variational problem involving higher order derivatives is considered and optimality condi-tions for this problem are derived. A Mond-Weir type dual to this problem is constructed and various duality results are validated under generalized invexity. Some special cases are mentioned and it is also pointed out that our results can be considered as a dynamic generalization of the already existing results in nonlinear programming.

American Journal of Operations Research (AJOR) , 2012, DOI: 10.4236/ajor.2012.23035
Abstract: A Mond-Weir type second-order dual continuous programming problem associated with a class of nondifferentiable continuous programming problems is formulated. Under second-order pseudo-invexity and second-order quasi-invexity various duality theorems are established for this pair of dual continuous programming problems. A pair of dual continuous programming problems with natural boundary values is constructed and the proofs of its various duality results are briefly outlined. Further, it is shown that our results can be regarded as dynamic generalizations of corresponding (static) second-order duality theorems for a class of nondifferentiable nonlinear programming problems already studied in the literature.

I. Husain, Vikas K. Jain
American Journal of Operations Research (AJOR) , 2012, DOI: 10.4236/ajor.2012.24063
Abstract: Fritz John and Karush-Kuhn-Tucker type optimality conditions for a nondifferentiable multiobjective variational problem are derived. As an application of Karush-Kuhn-Tucker type optimality conditions, Mond-weir type second-order nondifferentiable multiobjective dual variational problems is constructed. Various duality results for the pair of Mond-Weir type second-order dual variational problems are proved under second-order pseudoinvexity and second-order quasi-invexity. A pair of Mond-Weir type dual variational problems with natural boundary values is formulated to derive various duality results. Finally, it is pointed out that our results can be considered as dynamic generalizations of their static counterparts existing in the literature.
