Soft tissue sarcomas are malignant tumors characterized by heterogeneity and are associated with a high mortality rate. Histopathological grading is considered a pivotal factor in prognostication and treatment planning. While core needle biopsy exhibits high accuracy in determining tumor histology, it fails in some cases, potentially misclassifying high-grade tumors as low-grade.

Article Synopsis
  • - Long QT syndrome (LQTS) is a heart condition caused by prolonged electrical repolarization, which can lead to serious arrhythmias, and is identified through an extended QT interval on an electrocardiogram (ECG).
  • - Treatment typically involves beta-blockers for higher-risk patients, while lifestyle changes and regular monitoring apply to intermediate and low-risk patients; implantable cardioverter-defibrillators (ICDs) may be necessary for those with severe cases.
  • - Despite advancements in AI aiding diagnosis and management, significant gaps in understanding LQTS remain, indicating a need for further research on risk stratification and personalized treatment strategies.

Article Synopsis
  • Brugada syndrome (BrS) is an inherited heart condition that leads to abnormal heart rhythms and an increased risk of sudden cardiac death, primarily caused by mutations in the SCN5A gene.
  • Diagnosis can be tricky due to its hidden ECG signs and symptoms that resemble other heart disorders, mostly affecting young, healthy males.
  • Treatment mainly involves managing symptoms and preventing sudden death, primarily through implantable cardioverter-defibrillators (ICDs), with recent advancements in catheter ablation and specific medications like quinidine showing promise despite challenges in long-term management and availability.

Introduction Renal failure, comprising acute kidney injury (AKI) and chronic kidney disease (CKD), involves a decline or loss of kidney function. AKI is sudden and reversible, with a rapid decline in function over hours to days, while CKD involves persistent abnormalities lasting at least three months. Developing countries are seeing a rise in AKI cases, especially in critically ill patients.

Multiple sclerosis (MS) is a chronic autoimmune disease that affects the central nervous system (CNS). Neuropathic pain in MS is a debilitating symptom that significantly impairs the quality of life for a substantial proportion of MS patients. Neuropathic pain in MS stems primarily from demyelination, axonal loss, CNS inflammation, and direct damage to the myelin sheath, leading to pain manifestations such as ongoing extremity pain, Lhermitte's phenomenon, and trigeminal neuralgia (TN).

Neuropathic pain (NP), resulting from damage to the somatosensory system, is characterized by either spontaneous or evoked pain. In the context of NP, wherein aberrant signaling pathways contribute to the perception of pain, the thalamus emerges as a key player. This structure is integral to the pain network that includes connections to the dorsal horn of the spinal cord, highlighting its role in the affective-motivational aspects of pain perception.
