A large number of studies has demonstrated that abnormalities of coronary microcirculation may be responsible for both acute and chronic cardiac ischemic syndromes. In clinical practice the microvascular origin of myocardial ischemia and angina is usually considered in patients who are found to have normal or near-normal coronary arteries at angiography. In this article, we review the diagnostic approach to patients with suspected coronary microvascular dysfunction as a cause of ischemic syndromes and also suggest a classification of chronic and acute microvascular coronary ischemic syndrome, including myocardial infarction with normal coronary arteries.

Wearable bioelectronics have transformed modern biomedical applications by enabling seamless integration with biological tissues, providing continuous, comprehensive, and personalized healthcare. Skin cancer, particularly melanoma, poses a significant clinical challenge due to its high metastatic potential and associated mortality. Traditional diagnostic approaches face limitations in accuracy, accessibility, and reproducibility, while existing treatments are often constrained by systemic toxicity and therapeutic resistance.

Animal allergens, particularly those from cats, dogs, and horses, are significant risk factors for the development of allergic diseases in childhood. Managing animal allergies requires allergen avoidance and, when this is not feasible, specific immunotherapy. Patient history remains the cornerstone of diagnosis, providing the foundation for diagnostic algorithms.

Background: Intractable paroxysmal sneezing is a rare and diagnostically challenging condition in children, often mimicking organic diseases. While it is often addressed as psychogenic in the literature, our case presented findings suggestive of a tic disorder, highlighting the need for a broader diagnostic perspective.
Case Presentation: An 11-year-old girl was referred to the child and adolescent psychiatry clinic with a one-year history of persistent and fluctuating sneezing episodes.

Background: Sarcomas are rare cancer with a heterogeneous group of tumors. They affect both genders across all age groups and present significant heterogeneity, with more than 70 histological subtypes. Despite tailored treatments, the high metastatic potential of sarcomas remains a major factor in poor patient survival, as metastasis is often the leading cause of death.

Despite the promise of electrochemical biosensors in amplified nucleic acid diagnostics, existing high-sensitivity platforms often rely on a multilayer surface assembly and cascade amplification confined to the electrode interface. These stepwise strategies suffer from inefficient enzyme activity, poor mass transport, and inconsistent probe orientation, which compromise the amplification efficiency, reproducibility, and practical applicability. To address these limitations, we report a programmable dual-phase electrochemical biosensing system that decouples amplification from signal transduction.
