purpose: to evaluate the diagnostic signs, intraoperative complications and postoperative outcomes in children with congenital cataract and pre-existing posterior capsule defect (ppcd). methods: this interventional case series was conducted on 14 eyes of 7 patients who underwent lensectomy-anterior vitrectomy for congenital cataract with ppcd. all children had bilateral cataract. preoperative d...

INTRODUCTION Conversion of multiple hepatic arteries into a single vascular supply is a very important technique for repeat hepatic arterial infusion chemotherapy using an implanted port catheter system. Catheterization of a replaced left hepatic artery arising from a left gastric artery using a percutaneous catheter technique is sometimes difficult, despite the recent development of advanced i...

In vivo transfection is an important technique used in biological research and drug therapy development. Previously, we developed a renal pressure-mediated transfection method performed by pressing a kidney after an intravenous injection of naked nucleic acids. Although this is a useful method because of its safety and wide range of applications, an innovative approach for performing this metho...

PURPOSE The role totally implantable vascular devices (TIVAD) have an important role in providing care to cancer patients who require continuous or frequent venous access route either for their primary or supportive care treatments. This retrospective study aimed to analyze the efficacy of TIVAD and device-related complications. METHODS A total of 324 consecutive patients (185 male,139 female...

Metastatic tumors and malignant gliomas make up the majority of cancers in the brain. They are invariably fatal and there is currently no cure. From in vitro comparisons of a number of viruses, we selected one that appeared the best in selectively killing glioblastoma cells. This replication-competent virus, the glioma-adapted vesicular stomatis virus strain VSVrp30a, was used for in vivo tests...

Adequate catheter tip location is crucial for functional intravenous port and central venous catheter. Numerous complications were reported because of catheter migration that caused by inadequate tip location. Different guidelines recommend different ideal locations without consensus. Another debate is actual movement of intravascular portion of implanted catheter. From literature review, the c...

Acquired port-wine stain is a rare vascular lesion that mimics a congenital port-wine stain clinically and histologically, but is acquired after birth. A survey on more than 60 reported cases in the literature reveals that most of these cases are idiopathic, but some of the cases developed after physical or mechanical trauma, hormonal changes, chronic sun exposure, and medications (OCP, i...

Local cerebral blood flow (1CBF) was measured simultaneously in ten cats with (1) a large surface thermal diffusion probe resting on the cortex and (2) hydrogen clearance curves from implanted electrodes surrounding the thermal probe. A close correlation was found between 1CBF values obtained by the two methods. Since hydrogen clearance is accepted as quantitative, the data suggest that the the...
