Coronary artery spasm (CAS) rarely worsens from single-vessel to simultaneous multivessel CAS naturally, and simultaneous multivessel CAS leads to serious conditions such as cardiopulmonary arrest (CPA). A 77-year-old Japanese man who took medications for CAS was transferred to our hospital due to persistent chest pain. On arrival, his vital signs were stable, but his electrocardiogram (ECG) showed ST-segment elevation in leads II, III and aVF. Ventricular fibrillation developed suddenly. Although routine cardiopulmonary resuscitation (CPR) including intravenous administration of epinephrine was performed immediately, he could not be resuscitated...

BACKGROUND: Patients hospitalized for suspected acute coronary syndrome (ACS) are at risk for transient myocardial ischemia. During the "rule-out" phase, continuous ECG ST-segment monitoring can identify transient myocardial ischemia, even when asymptomatic. However, current ST-segment monitoring software is vastly underutilized due to false positive alarms, with resultant alarm fatigue. Current ST algorithms may contribute to alarm fatigue because; (1) they are not designed with a delay (minutes), rather alarm to brief spikes (i...

We describe a 44-year-old female with triple-negative breast cancer who developed skin erythaema, sclerosis and contracture of her entire right breast 15 months after completion of post-lumpectomy chemotherapy and radiotherapy, consistent with post-irradiation morphoea (PIM). PIM is a rare complication of breast irradiation that impairs a patient's quality of life. PIM is located usually at the radiation port or in the surrounding tissue. Clinically, PIM is misdiagnosed commonly as lymphoedema and cellulitis in the early inflammatory phase, and recurrent breast cancer, chronic radiodermatitis (CRD), radiation-induced fibrosis (RIF), post-irradiation pseudosclerodermatous panniculitis (PIPP), atypical vascular lesions (AVL) or angiosarcoma (AS) in the late burnout phase...

Atypical vascular lesions (AVLs) of the breast are rare cutaneous vascular proliferations that appear as flesh-colored or erythematous papules or macules in women who have undergone radiation treatment for breast carcinoma. These lesions can develop in the irradiated area up to 20 years after the radiation treatment but most commonly occur within 3 to 6 years. The general consensus agrees on the benign nature of AVLs; however, their identity as benign lesions has been a source of controversy over the years, with some investigators proposing that AVLs may be a precursor lesion to postirradiation angiosarcomas...

The 2014 Ebola outbreak in West Africa required the rapid testing of clinical material for the presence of potentially high titre Ebola virus (EBOV). Safe, fast and effective methods for the inactivation of such clinical samples are required so that rapid diagnostic tests including downstream analysis by RT-qPCR or nucleotide sequencing can be carried out. One of the most commonly used guanidinium - based denaturing agents, AVL (Qiagen) has been shown to fully inactivate EBOV once ethanol is added, however this is not compatible with the use of automated nucleic acid extraction systems...

Myocardial infarctions are frequently complicated by tachyarrhythmias, which commonly have wide QRS complexes (QRS duration > 120 milliseconds). Many published criteria exist to help differentiate between ventricular and supraventricular mechanisms. We present a case of a 61-year-old male with a history of hypertension, hyperlipidemia and coronary artery disease with prior stenting of the right coronary artery (RCA). He had been noncompliant with his antiplatelet medication and presented with cardiac arrest secondary to in-stent thrombosis...

BACKGROUND: Anaphylaxis is an acute, potentially fatal medical emergency. Myocardial injury or infarction in the setting of an anaphylaxis can be due the anaphylaxis itself, when it is known as Kounis syndrome or it can also be due to the effect of epinephrine treatment. Epinephrine is considered as the cornerstone in management of anaphylaxis. Myocardial infarction secondary to therapeutic doses of adrenaline is a rare occurrence and only a few cases have been reported in literature...

Luobuma (Apocynum venetum L. (AVL)) is a popular beverage in Asia and has been reportedly to be associated with the bioactivities such as cardiotonic, diuretic, antioxidative, and antihypertensive. However, its biofunction as chemoprevention activity is seldom addressed. Herein, we aimed to characterize the anti-androgen-insensitive-prostate-cancer (anti-AIPC) bioactive compounds of Luobuma, and to investigate the associated molecular mechanisms. Activity-guided-fractionation (antioxidative activity and cell survivability) of Luobuma ethanolic extracts was performed to isolate and characterize the major bioactive compounds using Ultra Performance Liquid Chromatography (UPLC), Liquid Chromatography-Mass Spectrometry (LC-MS), and Nuclear Magnetic Resonance (NMR)...

Autism spectrum disorder (ASD) is associated with two core symptoms (social communication deficits and stereotyped repetitive behaviors) in addition to a number of comorbidities. There are no FDA-approved drugs for the core symptoms and the changes that underlie these behaviors are not fully understood. One hypothesis is an imbalance of the excitation (E)/inhibition (I) ratio with excessive E and diminished I occurring in specific neuronal circuits. Data suggests that both gamma-aminobutyric acidA (GABAA) and α7 nicotinic acetylcholine receptors (nAChRs) significantly impact E/I...
