A Case of Emergency Pericardial Drainage for Cardiac Tamponade Due to Dengue Fever.

Dengue fever is a febrile viral disease transmitted by mosquitoes. The symptoms of dengue fever are numerous and varied; however, cardiac tamponade is a particularly rare and atypical complication. This study describes a case of a 30-year-old male who presented with acute respiratory distress and chest pain on the ninth day after diagnosis of dengue fever.

Nutritional Genomics and Cancer Prevention.

The scientific innovations have emphasized the importance of diet for one's health and wellbeing. The genetic revolution has enhanced our understanding about the effect of nutrients on genomic and transcriptomic profiles and gene-nutrition interactions (nutritional genomics). Furthermore, the contribution of micronutrient insufficiencies and macronutrient excess is evident in the development and progression of many diseases, especially cancer.

Virtual Reality Training Using Nintendo Wii Games for Patients With Stroke: Randomized Controlled Trial.

Background: Stroke is a leading cause of disability. It is difficult to devise an optimal rehabilitation plan once stroke survivors are back home. Conventional rehabilitative therapies are extensively used in patients with stroke to recover motor functioning and disability, but these are arduous and expensive.

Diagnosis of coronary artery fistulas: clinical aspects and brief review of the literature.

An 86-year-old woman with history of hypertension, diabetes, hyperlipidemia, and coronary artery disease was admitted with new-onset congestive heart failure and pneumonia. She underwent coronary angiography after suffering a non-ST elevation myocardial infarction. There was severe coronary artery disease in addition to coronary artery-pulmonary fistulas involving proximal right coronary artery and a branch of left main coronary artery.

Initial presentation of pheochromocytoma with Takotsubo cardiomyopathy: a brief review of literature.

Takotsubo cardiomyopathy, or transient left ventricular apical ballooning or broken heart syndrome, is characterized by excessive sympathetic stimulation induced acute coronary vasospasm. A 46-year-old female presented with polyuria and polydypsia and was diagnosed with new-onset diabetes mellitus, treated with insulin and intravenous fluids. During the hospital stay, she complained of an episode of left-sided chest pain and had mildly elevated cardiac enzymes.

Cardiac troponin I in sickle cell crisis.

Gross and microscopic findings consistent with acute and healed myocardial injury without coronary artery disease have been described in autopsy studies of patients with sickle cell crisis. The present study was designed to determine whether serum levels of cardiac troponin I are elevated in sickle cell crisis. Cardiac troponin I levels were measured in 32 patients age>18 years with the admission diagnosis of sickle cell crisis.

Hypothermia: evaluation, electrocardiographic manifestations, and management.

Hypothermia-related cases typically occur after exposure to low ambient temperatures; however, numerous cases occur in individuals with no history of exposure to cold environment. Hypothermia is associated with such complications as acidosis, impaired myocardial function, bleeding diathesis, and decreased kidney and liver function. The well-known electrocardiographic manifestations of hypothermia are the presence of J (Osborn) waves, prolonged PR, QRS, and QT intervals, and atrial arrhythmias.

Staphylococcus aureus infective endocarditis and septic pulmonary embolism after septic abortion.

We report a case of a 26-year-old female who after septic abortion developed tricuspid valve endocarditis with large vegetations, which subsequently resulted in embolism to right main pulmonary artery. Patient was treated with intravenous antibiotics and had a good recovery.

Hyperkalemia induced failure of atrial and ventricular pacemaker capture.

Hyperkalemia is a life threatening metabolic condition. The common risk factors for hyperkalemia include renal insufficiency, use of angiotensin converting enzyme inhibitors, potassium supplementation and excessive consumption of potassium containing diet. A mild to moderate increase in serum potassium causes an increase in myocardial excitability, but further increase leads to impaired myocardial responsiveness, including that to pacing stimulation.

Primary lymphedema tarda in an 88-year-old African-American male.

Primary lymphedema tarda is considered to be a congenital disease with delayed manifestations. We report a case of isolated lymphedema of the left upper extremity in an 88-year-old African-American male. The diagnosis of lymphedema was confirmed by lymphoscintigraphy, and appropriate diagnostic studies were done to rule out other known causes of lymphedema.

Cardiac effects of acute myelitis.

Neurogenic stunned myocardium has been described in association with subarachnoid hemorrhage, Guillain-Barre syndrome, and metastatic brain tumors. We describe a case of neurogenic stunned myocardium associated with acute myelitis. A 27-year-old female presented with acute onset of quadriplegia, sensory deficit, and acute pulmonary edema.

Fatal splenic sequestration crisis with multiorgan failure in an adult woman with sickle cell-beta+ thalassemia.

Acute splenic sequestration crisis is a potentially fatal condition mostly seen in children with sickle cell anemia (HbSS) up to 6 years of age. Sickle cell-beta thalassemia has been associated with development of splenic sequestration crisis in rare reports. There have also been rare reports of the development of fatal acute splenic sequestration crisis together with severe multiorgan failure in adult patients with sickle cell-beta thalassemia.

QT interval prolongation in diphenhydramine toxicity.

Diphenhydramine overdose in one of the frequent reported causes of acute poisoning. Patients with diphenhydramine overdose can present with central nervous system manifestations, anticholinergic manifestations and cardiovascular symptoms. The cardiovascular symptoms of diphenhydramine overdose include myocardial depression and refractory hypotension.
