Afebrile scrub typhus infection with cardiac manifestation.

Scrub typhus is an acute febrile disease transmitted via bites from mite larvae (chigger) infected with Orientia tsutsugamushi. Arrhythmias, ischaemic changes and QT prolongation are some of the observed ECG abnormalities. The patient being reported presented with angina and was found to have sinus bradycardia with ST elevation in inferior leads and T wave inversion in lateral leads. His coronary angiography was normal. Further evaluation leads to the diagnosis of scrub typhus infection. Following doxycycline therapy, his ECG became normal. Afebrile scrub typhus infection with cardiac manifestation is an uncommon scenario.

Hyperkalemic Cardiac Arrest in a Patient with Diabetic Ketoacidosis.

AIM: To highlight the occurrence of cardiac arrest due to hyperkalemia in diabetic ketoacidosis (DKA). BACKGROUND: Diabetic ketoacidosis is a commonly encountered condition. These patients can have normal or mildly elevated levels of potassium. Our patient had severe hyperkalemia due to DKA resulting in cardiac arrest. Her high potassium diet and use of angiotensin receptor blocker along with acute kidney injury (AKI) would have also contributed to hyperkalemia. CASE DESCRIPTION: A 58-year-old female, known case of diabetes mellitus on insulin therapy and hypertension on telmisartan, presented with nausea, vomiting, and abdominal pain. She was diagnosed to have DKA with AKI precipitated by missed insulin and urinary tract infection. She was also on high potassium diet. Her electrocardiogram showed sinus bradycardia with prolonged QRS interval. Her potassium levels were elevated. She soon went into asystole and cardiac arrest and was resuscitated. Diabetic ketoacidosis protocols were followed along with antibiotics, and the patient improved. CONCLUSION: Severe hyperkalemia in DKA is uncommon, and this hyperkalemia resulting in cardiac arrest is an unreported scenario. Potassium correction along with DKA management protocol forms the mainstay of treatment. CLINICAL SIGNIFICANCE: Mild to moderate elevation in serum potassium occurs frequently in DKA. However, severe hyperkalemia is uncommon and is likely to be the result of insulin deficiency, acidosis, hyperosmolality, severe dehydration, and renal potassium retention. Such elevated level of potassium requires urgent correction in order to prevent cardiac arrest. HOW TO CITE THIS ARTICLE: Manappallil RG, Nambiar J.

Non-ST-Elevation Myocardial Infarction in a Case of Von Willebrand Disease: a Case Report.

INTRODUCTION: Studies have shown that patients with Von Willebrand disease (VWD) have decreased prevalence of thrombotic events like myocardial infarction (MI). Here we describe a case of VWD with acute non-ST-elevation MI with ongoing bleeding manifestations. CASE PRESENTATION: A 37-year-old female patient presented to the emergency department with a complaint of central chest pain since 7 days. She also had a history of hemoptysis since 8 days. Electrocardiogram (ECG) revealed ST-segment depression in leads I, aVL, II, III, aVF, and V4-V6 compatible with diagnosis of Non-ST-Elevation Myocardial Infarction (Non STEMI). She was started on nitroglycerine infusion, angiotensin II receptor blockers, and calcium channel blockers along with trimetazidine. Her chest pain and ECG changes settled after 2 days, and she was discharged in a stable condition. CONCLUSION: There are limited studies available regarding the management of acute MI in VWD patients with acute bleeding manifestations. Further studies have to be carried out to determine successful ways of managing thrombotic events like MI in this subset of patients.
