A case of early repolarization syndrome in which hyponatremia and coronary vasospasms induced ventricular fibrillation.

A 60-year-old man was referred to our hospital presenting with unconsciousness due to severe hyponatremia. The twelve‑lead ECG on admission exhibited prominent J waves in the inferolateral leads. During the treatment for hyponatremia, ventricular fibrillation (VF) occurred and the electrogram (ECG) after the VF incident exhibited marked ST elevation in the inferolateral leads.

Current Perspectives of Mitochondria in Sepsis-Induced Cardiomyopathy.

Sepsis-induced cardiomyopathy (SICM) is one of the leading indicators for poor prognosis associated with sepsis. Despite its reversibility, prognosis varies widely among patients. Mitochondria play a key role in cellular energy production by generating adenosine triphosphate (ATP), which is vital for myocardial energy metabolism.

A case of repeated Kounis syndrome after anaphylactic shock: A note for disease management.

Background: Kounis syndrome (KS) is an underdiagnosed disease. The management of the disease remains elusive because of its infrequency.

Case Presentation: A 78-year-old man with anaphylactic shock was admitted to our hospital 2 h after multiple bee stings.

A case of toxic epidermal necrolysis comorbid with severe burns.

Unlabelled: Toxic epidermal necrolysis (TEN) and severe burns both have high mortality rates, but coexistence is extremely rare. The specificity of developing TEN in burn patients is not well understood and its treatment strategy is not established.

Case Presentation: A 68-year-old man was carried to our hospital with severe burns covering 35% of his body surface area.

A case of COVID-19-associated fulminant myocarditis successfully treated with mechanical circulatory support.

A 49-year-old man, who had not been vaccinated against COVID-19 visited the hospital for fever and cough, and a PCR test for COVID-19 was positive on the Day X. Initially, there was no decrease in oxygen saturation and the patient was under observation as a mild case without medication. Five days after the onset (Day X + 5), chest pain appeared.

Minimal change nephrotic syndrome associated with gefitinib and a successful switch to erlotinib.

Minimal change nephrotic syndrome (MCNS) is a common form of nephrotic syndrome (NS). We herein present the case of a 57-year-old woman with advanced lung adenocarcinoma treated with the tyrosine kinase inhibitor (TKI) gefitinib who developed NS. A renal biopsy revealed minor glomerular abnormalities, and the patient's symptoms improved exclusively with the discontinuation of gefitinib.
