Two cases are described in which spinal cord stimulation was effective in abolishing previously intractable deafferentation pain for a number of years, but in which late failure occurred for non-technical reasons. A possible explanation for this is advanced; namely that the dorsal column fibres have altered electrical properties due to a form of transganglionic degeneration.

Drug discovery continues to face a staggering 90% failure rate, with many setbacks occurring during late-stage clinical trials. To address this challenge, there is an increasing focus on developing and evaluating new technologies to enhance the "design" and "test" phases of antibody-based drugs (e.g.

Background: Multisystem inflammatory syndrome in neonates (MIS-N) is a rare condition thought to be associated with prenatal exposure to maternal severe acute respiratory syndrome coronavirus 2 infection. This immune-mediated hyperinflammation has been described in neonates with multiorgan dysfunction, including cardiopulmonary, encephalopathy, coagulopathy, and vascular complications. However, renovascular complications in MIS-N are rare.

Dilated cardiomyopathy (DCM) is the ultimate manifestation of the myocardial response to various genetic and environmental changes and is characterized mainly by impaired left ventricular systolic and diastolic function. DCM can ultimately lead to heart failure, ventricular arrhythmia (VA), and sudden cardiac death (SCD), making it a primary indication for heart transplantation. With advancements in modern medicine, several novel techniques for evaluating myocardial involvement and disease severity from diverse perspectives have been developed.

Pancreatic carcinoma has remained one of the leading causes of cancer-related mortality worldwide. Cancer originating in the head of pancreas is often detected early in the disease due to biliary obstruction resulting in jaundice. In contrast, cancer of the pancreatic body and tail remains indolent, presenting late with significantly increased tumor burden and distant metastasis.
