AIMS To investigate the relationship between quantitative iris parameters and angle closure disease. methods: Participants with angle closure were recruited prospectively from glaucoma clinics. Anterior segment optical coherence tomography (AS-OCT) was performed under standardised dark conditions. Customised software was used on horizontal AS-OCT scans to measure iris thickness at 750 um...

BACKGROUND The role of percutaneous closure of patent foramen ovale (PFO) in patients with cryptogenic stroke or transient ischemic attack remains controversial. Registry data have suggested considerable benefit of closure over medical therapy, but the prospective, randomized CLOSURE I trial found no benefit for device closure. METHODS We compared patients enrolled into CLOSURE I to off-label...

In a previous paper [3], the author gave an explicit description of the algebraic closure of the power series field over a field of characteristic p > 0, in terms of certain “generalized power series”. The purpose of the present paper is to extend this work to mixed characteristic. Specifically, we give an analogous description of the algebraic closure of the Witt ring W (K) of an algebraically...

Gopalan et al. studied in [14] connectivity properties of the solution-space of Boolean formulas, and investigated complexity issues on connectivity problems in Schaefer’s framework [26]. A set S of logical relations is Schaefer if all relations in S are either bijunctive, Horn, dual Horn, or affine. They conjectured that the connectivity problem for Schaefer is in P . We disprove their conject...

PURPOSE Wound infection after an ileostomy reversal is a common problem. To reduce wound-related complications, purse-string skin closure was introduced as an alternative to conventional linear skin closure. This study is designed to compare wound infection rates and operative outcomes between linear and purse-string skin closure after a loop ileostomy reversal. METHODS Between December 2002 ...

OBJECTIVES We sought to evaluate the benefits on frequency and severity of migraine recurrence after patent foramen ovale (PFO) closure in patients with subclinical brain lesions at magnetic resonance imaging (MRI). BACKGROUND Migraine improvement has been reported after PFO closure in patients with cerebrovascular symptomatic events. Subclinical brain MRI lesions are detectable in patients w...

Background: It has been estimated that 67 million people worldwide are affected with a primary glaucoma and that one-third have primary angle closure glaucoma. We aimed to determine the biometric differences between the eyes of patients with acute attack of primary angle closure and their non-involved fellow eyes. Methods: Twenty eight patients with acute attack of primary angle closure were re...

Let W be a q-dimensional irreducible algebraic subvariety in the affine space AC, P1, ..., Pm m elements in C[X1, ..., Xn], and V (P ) the set of common zeros of the Pj ’s in Cn. Assuming that |W | is not included in V (P ), one can attach to P a family of non trivial W -restricted residual currents in ′D0,k(Cn), 1 ≤ k ≤ min(m, q), with support on |W |. These currents (constructed following an ...

We show experimentally that the route to chaos is via intermittency in a shear-thinning wormlike micellar system of cetyltrimethylammonium tosylate, where the strength of flow-concentration coupling is tuned by the addition of salt sodium chloride. A Poincaré first return map of the time series and the probability distribution of laminar lengths between burst events shows that our data is consi...

Aims: To evaluate the clinical significance of macular hole closure types assessed by optical coherence tomography (OCT). Methods: This study involved 34 eyes of 32 patients who had undergone anatomically successful idiopathic macular hole surgery. The closed macular holes were categorised into two patterns based on OCT; type 1 closure (closed without foveal neurosensory retinal defect) and typ...
