Bernoulli Equation in the Mitral Valve of Heart

In the past decade, finite element modeling of complete heart valves has greatly aided evaluation of heart valve surgery, design of bioprosthetic valve replacements, and general understanding of healthy and abnormal cardiac function. Such a model must be based on an accurate description of the mechanical behavior of the valve material. It is essential to calculate velocity/displacement, geometrical indices and strain rate/strain at a component level that is to work at the cellular level.

Endocardial Approach for Substrate Ablation in Brugada Syndrome: Epicardial, Endocardial or Transmural Substrate?

Background: Radiofrequency ablation (RFA) in Brugada syndrome (BrS) has been performed both endocardially and epicardially. The substrate in BrS is thus unclear. Objectives: To investigate the functional endocardial substrate and its correlation with clinical, electrophysiological and ECG findings in order to guide an endocardial ablation. Methods: Thirteen patients (38.7±12.3 years old) with spontaneous type 1 ECG BrS pattern, inducible VF with programmed ventricular stimulation (PVS) and syncope without prodromes were enrolled. Before to endocardial mapping the patients underwent flecainide testing with the purpose of measuring the greatest ST-segment elevation for to be correlated with the size and location of substrate in the electro-anatomic map

Superior Mesenteric Artery Embolus as a Delayed Complication of a Cocaine Induced Myocardial Infarction

Cocaine has acute and chronic effects on health as well as addiction and dependence and places a significant burden on healthcare systems. After cannabis, it is the most frequently used illicit drug worldwide. It is estimated that between 14 and 21 million people use the drug each year [1]. Its main adverse effects occur in the cardiovascular system. Cocaine causes sympathomimetic actions such as tachycardia, hypertension and coronary artery constriction due to enhancement of release of catecholamines. It enhances thrombus formation by activating platelets and potentiating thromboxane production [2]. The consequences of these effects include chest pain, myocardial infarction, aortic dissection, coronary artery aneurysm, myocarditis, cardiomyopathies and arrhythmias. Our case demonstrates a young patient who had a delayed presentation of a myocardial infarction, in the setting of recent cocaine use that was complicated by an apical thrombus which resulted in distal emboli to his superior mesenteric artery and left renal artery. It highlights the fact that in a young patient with no other risk factors how complications may arise, even weeks after cocaine use.

Macrocystis of the Lung in a Preterm Neonate: Case Report

Thoracic ultrasonography has been used to evaluate pulmonary parenchyma and the macrocystis of the lung in a preterm with congenital cystic adenomatoid malformation type I. The images gained have been important for diagnosis and therapeutic strategies in our case. An infant was prematurely born with congenital cystic adenomatoid malformation type I. The chest X-ray and computerized tomography showed a great opaque area in the entire right lung, we considered performing a pneumonectomy. This opaque area hampered the expansion of left lung. After draining the macrocystis by ultrasonography-guided puncture, it was possible considering and performing the lobectomy due to the reduction of the volume of macrocystis. During follow up at 4 months, the infant did not show complications and the chest X-ray revealed the reduction of volume of the dense area in parenchyma of right lung.

Metabolic Syndrome in Indigenous Amerindian Women in Suriname; Less on Waist and More on Weight?

The indigenous Amerindian populations living in the southern interior part of Suriname have to date largely maintained their traditional hunter-gatherer life-style. In this study we compared the prevalence of metabolic syndrome (MeTS) and its component risk factors between indigenous Amerindian women of the interior of Suriname, with indigenous Amerindian women living in the coastal-rural areas who have a more urbanized lifestyle. We focused on women since the Suriname Health study showed that Indigenous women had the second highest MeTS prevalence nationwide.

Infective Endocarditis at Tricuspid Valve in CHD: What are its Characteristics? What is the Pathophysiology?

Infective endocarditis (IE) is a serious infectious disease that carries a high mortality rate. We report the case of 74-year-old female who is a chronic hemodialysis patient, and was presented with tricuspid valve endocarditis (TVIE) with central venous catheter, due to an Enterobacter Cloacae, which is a non-HACEK Gram-negative bacilli (GNB) and has been reported to be an extremely rare pathogen of IE. The patient was treated with imipenem and teicoplanin for a four-week period, with negative Blood culture and normal C reactive protein (CRP) levels at the end. The aim of our study is to understand the pathophysiology of the IE in chronic renal failure (CRF) especially at the tricuspid valve (TV), and to determine the clinical, biological characteristics and therapeutic modalities.

Ventricular Arrhythmia Due to Yellow Phosphorus Poisoning

Ratol paste (Yellow Phosphorus) is a local and systemic toxin affecting almost all the organs of the body especially liver, kidney, brain and heart. There is no specific antidote for yellow phosphorus poisoning. Heart is one of the many organs affected by the YP. However cardiac toxicity following acute ingestion of YP has been reported rarely.

Factors associated with obesity among Saudi women of reproductive age in Jeddah City

Previous studies have shown that women who are overweight or obese are at risk for adverse reproductive outcomes, including infertility, gestational diabetes, and hypertensive disorders of pregnancy. However, information surrounding the risk factors for obesity among Saudi women of reproductive age is deficient due to the limited number of studies that assessed obesity prevalence among them.

Dental Implant Complications –Systemic Diseases- PART-I

Although dental implants have been a successful option for replacement of lost dentition for nearly five decades, their use in the medical and dental treatment plan is still in its youth. Literature on the medical implications of dental implants is surprisingly sparse, with a need for organization. This review is an attempt to begin the process of documenting the science behind this complex, yet critical topic.

The Use of Cardiac Resynchronization Therapy in Cancer Patients with Heart Failure

Investigate the use of cardiac resynchronization therapy (CRT) in cancer patients with heart failure (HF); assess factors associated with ischemic and non-ischemic HF. Many newer cancer therapies are cardiotoxic; thus, the incidence of HF has been increasing in this high-risk patient population. CRT has beneficial effects on morbidity, mortality, and left ventricular function in patients with non-ischemic cardiomyopathy, yet cancer patients and survivors who develop severe HF and are eligible for CRT often does not receive it.

Variation in the Incidence of Self-Immolation According To Culture and Income Level: A Literature Review

Self-immolation is most commonly observed in the Middle East and Western Asia. It is far less common in the Western world. Documented cases in the West indicate that victims are more likely to be immigrants, indicating that there may be cultural influences that motivate this behavior. We have performed a literature review on self-immolation in order to better understand the cultural differences behind selfimmolation and the psychopathology related to this specific behaviour.

Evaluating the Effect of Oprelvekin on Cardiac Repolarization in Subjects with Chemotherapy-Induced Thrombocytopenia: An Observational Chart Review of a Phase 2 Clinical Trial in Laredo, Texas

This study tested for the cardiac effects of Oprelvekin, recombinant human interleukin-11, a thrombopoietic growth factor, in patients afflicted with chemotherapy-induced thrombocytopenia (platelet count<50,000 cells/ul). Chart-reviews of patients fulfilling the inclusion criteria of: 18-75 yrs of age, non-myeloid malignancy, with adequate hematologic, hepatic and renal parameters and normal electrocardiograms that were enrolled in this phase 2 trial were analyzed. Patients of child-bearing potential agreed to be on a reliable form of birth control for the duration of the study. Results on 4 patients suggest that Oprelvekin does not cause atrial nor ventricular arrhythmia, a rare severe cardiac side effect, in treating patients with chemotherapy-induced thrombocytopenia.

Reprint Requests Were Useful in Cardiology Citations

The study sets out to compare personal studies from 1982 to 2003 as regards 8 articles on the role of the reprint request (RR) in fostering scientific communication. As early as 1986, the Editor of English for Specific Purposes cited the author as “the only active researcher” that he had “traced in the RR area.” In this context, 2 papers published in 1972 and 1974 in cardiology were presented together with 4 associated reprints. Actually, the study confirmed the phenomenon of “clustering.” Thus, US most active contemporaneous scientists were affiliated in only 8 of the entire states. Out of these, 2 states appeared in the local catchment. In other words, this means that the “tracer tool” function of RR has been demonstrated. However, the Internet is now predominant in such sociological studies; it will no doubt be useful in such tracings.
