There is no effective treatment for intracerebral hemorrhage (ICH). Intracerebral delivery of nanomaterials into the hemorrhagic lesion may be a new therapeutic strategy. In a rat model of ICH plus ultra-early hematoma aspiration, we found that locally delivered self-assembling peptide nanofiber scaffold (SAPNS) replaced the hematoma, reduced acute brain injury and brain cavity formation, and improved sensorimotor functional recovery. SAPNS serves as biocompatible material in the hemorrhagic brain cavity. Local delivery of this nanomaterial may facilitate the repair of ICH related brain injury and functional recovery. From the clinical editor: In a rat model of intracranial hemorrhage, these authors demonstrate that following ultra-early hematoma aspiration, local delivery of a self-assembling peptide nanofiber scaffold replaces the hematoma, reduces brain cavity formation, and improves sensorimotor functional recovery. Similar approaches would be welcome additions to the clinical treatment of this often devastating condition.

Long-term forced-use therapy after sensorimotor cortex lesions restores contralesional hand function and promotes its preference in Macaca mulatta.

Injury to one cerebral hemisphere can result in paresis of the contralesional hand and subsequent preference of the ipsilesional hand in daily activities. However, forced use therapy in humans can improve function of the contralesional paretic hand and increase its use in daily activities, although the ipsilesional hand may remain preferred for fine motor activities. Studies in monkeys have shown that minimal forced use of the contralesional hand, which was the preferred hand prior to brain injury, can produce remarkable recovery of function.

Background: Open and crushed forearm injury is a complex and rare injury affecting the upper extremity. It results in damage to various structures, including bones, soft tissues, and neurovascular bundles, ultimately leading to functional impairment. Typically, these injuries occur owing to high-energy trauma.

Background: Coronary Artery Spasm (CAS) often presents in the epicardial coronary arteries. The anterior septal branch is distributed within the myocardium, and occurrences of spasms are rare. Currently, there is no available literature on this topic, and the onset of symptoms remains elusive, potentially leading to misdiagnosis.

Epithelioid sarcomas are rare soft tissue tumors and have possibility to involve the peripheral nerve and present as sensory and motor disorders. The symptoms are similar to those of nerve compression diseases. This situation is extremely rare in clinic and was only reported as several case reports in literature.
