OBJECTIVES To review our experience with patients treated for anal fistula secondary to cryptoglandular disease and to determine factors that influence postoperative outcome. DESIGN Retrospective review. SETTING A regional tertiary referral center. PATIENTS Adult patients with anal fistula secondary to cryptoglandular disease. INTERVENTIONS Fistulotomy, advancement flap, and fistula plu...

INTRODUCTION Oscillating the head about a spatial horizontal axis activates both the vertical semicircular canals (VC) and the otolith organs. It is generally assumed that in-phase modulation of unit firing rate (FR) with head position indicates convergent otolith input, while in-phase modulation with head velocity indicates VC input. The amplitude of FR modulation depends on head orientation i...

Interstitial Randall's plaques and collecting duct plugs are distinct forms of renal calcification thought to provide sites for stone retention within the kidney. Here we assessed kidney stone precursor lesions in a random cohort of stone formers undergoing percutaneous nephrolithotomy. Each accessible papilla was endoscopically mapped following stone removal. The percent papillary surface area...

Introduction. Ear plugging (placing fingers in or covering the ears) is a clinical seizure semiology that has been described as a response to an unformed, auditory hallucination localized to the superior temporal neocortex. The localizing value of ear plugging in more complex auditory hallucinations may have more involved circuitry. We report on one child, whose aura was a more complex auditory...

Plugging of the capillary bed can lead to organ failure and mortality in sepsis. We have reported that intravenous ascorbate injection reduces platelet adhesion to the capillary wall and capillary plugging in septic mice. Both platelet adhesion and capillary plugging require P-selectin, a key adhesion molecule. To elucidate the beneficial effect of ascorbate, we hypothesized that ascorbate redu...

Dolipore septa and septal pore caps (SPCs) in filamentous basidiomycetes may play an important role in maintaining the integrity of hyphal cells. We have investigated the ultrastructure of the dolipore septum and the SPC in Rhizoctonia solani hyphal cells after high-pressure freezing, freeze substitution, and Spurr embedding. We visualized the SPC with associated cell ultrastructures in three d...

OBJECTIVE Cystic fibrosis (CF) is a rare congenital disease in Korea, and its clinical and imaging findings are unclear. The objective of our study was to describe the clinical and CT features of CF in Korea and compare its features with those of other diseases mimicking CF. MATERIALS AND METHODS From November 1994 to December 2014, a presumptive diagnosis of CF was made in 23 patients based ...

PURPOSE Onyx has been successfully applied in the treatment of various neurovascular lesions. However, some experience is required to get accustomed to its unpredictable fluoroscopic visibility during injection. This in vitro study aimed to evaluate the characteristics of radiopacity change in a simulated embolization procedure. MATERIALS AND METHODS Using a bench-top Onyx injection experimen...
