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.

Case Report of Severe Preeclampsia and Associated Postpartum Complications

Preeclampsia is clinically defined by hypertension and proteinuria, with or without pathologic edema that occurs after 20 weeks’ gestation, but can also present up to 4-6 weeks post-partum. Worldwide, incidence of preeclampsia is 5-14 percent of all pregnancies, while severe preeclampsia can develop to about 25 percent of all cases of preeclampsia.

Spontaneous Coronary Artery Dissection: Efficient Clinical Outcome through Percutaneous Coronary Intervention

Spontaneous coronary artery dissection (SCAD) is a rare myocardial ischemic disease that threatens patients’ life. Various risk factors are associated with SCAD, such as smoking, severe hypertension and psychological reasons. Considering the formation of dissection, SCAD can be divided into intimal tear type or intraluminal hemorrhage type.

Lethal Dance with Dialysis – A Case of Silent Long QT Syndrome

Fatal arrhythmia is the leading cause of mortality in chronic haemodialysis patients. Long QT syndrome is responsible for polymorphic ventricular tachycardia known as Torsade de Pointes. Classically, long QT syndromes were divided into congenital and acquired; however ‘silent’ variants, in which patients remain asymptomatic until exposed to a drug or electrolyte disturbance precipitating the arrhythmia, have now been recognized.

Effects of Pioglitazone on the Electrocardiogram in the Goto-Kakizaki Type 2 Diabetic Rat Heart

Cardiovascular complications are the major cause of morbidity and mortality in diabetic patients. Pioglitazone (PIO) is used for the treatment of type 2 diabetes mellitus and there is some evidence that it may improve ventricular function in diabetic patients.

Street Drug, an Inotrope in Heart Failure?

Methamphetamine is one of the most commonly abused illegal stimulants and causes the release of dopamine, norepinephrine and serotonin. These neurotransmitters trigger vasospasm, causing persistent tachycardia, hypertension, and direct myocardial toxicity. Moderate usage of methamphetamine can increase cardiac output and myocardial contractility. However, larger doses can cause depression of the myocardium.

Refractory Hypotension Caused By Prone Position in a Child Undergoing Scoliosis Corrective Surgery

We report a case of a teenager with scoliosis and pectus excavatum who developed intraoperative refractory hypotension associated with prone position during posterior surgical correction of scoliosis. In this case, it was more difficult for the anesthetists to figure out the reason leading to severe hypotension when a surgery was partially completed, because there might be many confounding factors during surgery. Furthermore, TEE was difficult to be considered to be first diagnosis choice when patient have already underwent posterior spinal fusion surgery, compared to the cases previous reported that the surgery still did not begin.

Heart Rate Variability and Occupational Stress: Future Directions

Statistics across industrialised societies show that occupational stress results in social and financial costs for individuals, organisations, and economies. Occupational stress is prevalent in many different forms, for example, work intensification, dissatisfaction with current work schedules, feelings of job insecurity, more work being done at odd hours, the spread of new information and communication technologies, and long hours becoming more common.
