Early diagnosis to avoid invasive treatment in cardiac migration of a ventriculoperitoneal catheter: a qualitative systematic review and Weibull analysis of case reports.
The migration of distal catheter after ventriculoperitoneal shunt placement is a rare but significant complication. Especially in a case of cardiac migration, open-heart surgery or catheter intervention may be required. The authors encountered a case of cardiac migration that fortunately could be treated by withdrawal. A systematic review of cardiac migration was performed to clarify when and how migration was diagnosed and why invasive treatments were required. Based on the collected cases, a Weibull analysis of the latency until diagnosis was performed to examine whether cardiac migration is caused by an initial factor and to compare the result with the other migration sites such as gastrointestinal tract or urinary tract. ⋯ In light of the previous reports, the latency until diagnosis of cardiac migration was associated with the rate of thrombosis and adhesion, which resulted in escalation to invasive treatment. Early diagnosis will prevent invasive treatment because most cases are caused by initial factors, as the Weibull analysis showed.

Association of rare variants in RNF213 with severe progression of intracranial artery stenosis in quasi-moyamoya disease.
The genetic basis underlying the pathophysiology of quasi-moyamoya disease (qMMD) is unclear. Herein, the authors aimed to comprehensively analyze genetic variants in qMMD and investigate their association with clinical phenotypes, focusing on RNF213 and other moyamoya angiopathy (MMA)-related genes. ⋯ While the clinical implications of p.Arg4810Lys in cases with qMMD were not identified, the study findings suggest a potential association between RNF213 RVs and the significant progression of intracranial artery stenosis. Genetic analysis should not focus solely on p.Arg4810Lys but instead consider a comprehensive analysis of RNF213 for more accurate clinical prognostication of qMMD.

Radiographic and neurological outcomes of Gamma Knife radiosurgery for lower cranial nerve schwannomas: a single-institution experience.
Gamma Knife radiosurgery (GKRS) is widely used for treating small- to medium-sized or postoperative residual, recurrent lower cranial nerve schwannomas (LCNSs). This study aimed to evaluate the radiographic and neurological outcomes of GKRS for LCNS. ⋯ GKRS is an alternative treatment option for LCNS that reduces surgical morbidity and enhances tumor control. However, GKRS can potentially lead to neurological deterioration, necessitating extreme caution throughout the procedure, specifically for JFSs.
