Article Synopsis
- This study aimed to assess how effective susceptibility-weighted imaging (SWI) is in detecting intracranial vertebral artery dissection (VAD) and unruptured intracranial aneurysms (UIAs).
- A total of 110 patients were evaluated using SWI, with 55 confirmed cases of either VAD (38.2%) or UIA (61.8%), focusing on specific image features that indicate these conditions.
- The findings showed that SWI had high sensitivity and specificity for detecting VAD and UIAs over 7 mm, highlighting significant agreements among observers on the results.
Aim: To compare the clinical results of femtosecond (FS) laser keratomileusis (LASIK) in high myopic patients and low myopic patients.
Methods: This study included 212 myopic eyes undergoing LASIK using a VisuMax 500kHz FS laser. All treated eyes were assigned to one of two groups according to preoperative manifest spherical refraction: low myopia group (A, >-4.
Background: To investigate the cytotoxicities of the topical ocular dual-action anti-allergic agents (alcaftadine 0.25%, bepotastine besilate 1.5%, and olopatadine HCL 0.

View Article and Find Full Text PDFBackground: The aim was to evaluate the clinical results of fitting MSD miniscleral contact lenses (MSD; Happy Vision Corp, Anyang, Korea) in Korean patients with keratoconus.
Methods: This report presents a retrospective case review of 38 keratoconic patients fitted with MSD lenses. Visual acuity, comfort, mean wear time, final lens parameters, relationships between sagittal depth and topographic indices, success rate with the first lens ordered and adverse events were documented.
Objective: To evaluate the usefulness of newly designed sheaths for gastroduodenal intervention in a gastric phantom and dogs.
Materials And Methods: A regular sheath was made using a polytetrafluoroethylene tube (4 mm in diameter, 90 cm long) with a bent tip (4 cm long, 100 degree angle). For the supported type of sheath, a 5 Fr catheter was attached to a regular sheath to act as a side lumen.
Rationale And Objective: Conventional vascular catheters or sizing catheters are often inconvenient and time-consuming for gastrointestinal procedures. Our purpose was to evaluate the feasibility of a newly designed coil catheter by experimental study in dogs.
Materials And Methods: Two catheter models were fabricated using a stainless-steel coil covered by heat shrinkable tube.
Purpose: To evaluate the feasibility of using a retrievable urethral stent and to evaluate whether granulation tissue resolves after stent removal in a canine urethra.
Materials And Methods: Polyurethane-covered retrievable 0.10-mm-thick (n = 11) or 0.
