#1
Abhijit Anand Mohite, Rangarajan V Prabhu, Thomas Ressiniotis
Purpose: Latanoprost has become one of the most widely prescribed topical antihypertensive medications in recent years. Yet there have been few reports of secondary iris pigment epithelial (IPE) and ciliary body (CB) cyst formation to date and none, to our knowledge, reported in eyes predisposed to primary angle closure. Methods: We report the first documented case of bilateral IPE and CB cysts in a hypermetropic patient with prior laser peripheral iridotomies (LPIs) as a rare, delayed side effect of topical Latanoprost treatment...

Four patients developed choroidal detachment within three months after trabeculectomy, documented with b-scan ultrasonography (BUS) and ultrasound biomicroscopy (UBM). Intraocular pressure (IOP) of the patients ranged from 3 to 5 mm Hg. Patients were treated with cycloplegia and steroids without complete resolution of detachment. Twelve months later all patients had developed visually significant cataracts and underwent phacoemulsification and intraocular lens implantation. Procedures were uncomplicated. Visual acuity ranged 0...

OBJECTIVE: To evaluate the clinical efficacy among ultrasound pachymetry (UP), ultrasound biomicroscopy (UBM), and manual measurement (MM) with digital caliper by comparing corneal thickness (COT) values obtained from frozen canine corneas ex vivo. PROCEDURES: COT was measured using UP, UBM, and MM in eight enucleated normal canine eyes frozen at -20 °C for 4 weeks. After thawing at room temperature for 2 h, the COT values were obtained from five sites on each cornea: central corneal thickness (CCOT), thickness at the 3, 6, 9, and 12 o'clock positions (3COT, 6COT, 9COT, and 12COT, respectively)...

Frank Bochmann, Jörg Strümer
PURPOSE: A subluxation or dislocation of the intraocular lens (IOL) is a well-known complication after cataract surgery in patients with pseudoexfoliation syndrome (PEX). Capsular tension rings (CTR) are frequently used to prevent postoperative complications caused by zonular weakness. Here we present a series of 7 cases, 2 with intermittent and 5 with acute angle closure caused by a combination of PEX-associated zonular weakness and a resulting unstable capsular bag-CTR-IOL complex. MATERIALS AND METHODS: We describe the typical clinical course with elevated intraocular pressure, myopic shift, and shallowing of the anterior chamber in 7 patients with a new type of secondary angle closure...

Stephen M Goldman, Benjamin T Corona
Minced muscle grafts (MG) promote de novo muscle fiber regeneration and neuromuscular strength recovery in small and large animal models of volumetric muscle loss. The most noteworthy limitation of this approach is its reliance on a finite supply of donor tissue. To address this shortcoming, this study sought to evaluate micronized acellular urinary bladder matrix (UBM) as a scaffolding to promote in vivo expansion of this MG therapy in a rat model. Rats received volumetric muscle loss injuries to the tibialis anterior muscle of their left hind limb which were either left untreated or repaired with minced muscle graft at dosages of 50% and 100% of the defect mass, urinary bladder matrix in isolation, or a with an expansion product consisting of a combination of the two putative therapies in which the minced graft is delivered at a dosage of 50% of the defect mass...

Electrocardiogram signals acquired through a steering wheel could be the key to seamless, highly comfortable, and continuous human recognition in driving settings. This paper focuses on the enhancement of the unprecedented lesser quality of such signals, through the combination of Savitzky-Golay and moving average filters, followed by outlier detection and removal based on normalised cross-correlation and clustering, which was able to render ensemble heartbeats of significantly higher quality. Discrete Cosine Transform (DCT) and Haar transform features were extracted and fed to decision methods based on Support Vector Machines (SVM), k-Nearest Neighbours (kNN), Multilayer Perceptrons (MLP), and Gaussian Mixture Models - Universal Background Models (GMM-UBM) classifiers, for both identification and authentication tasks...

Ultrasound biomicroscopy (UBM) is a valuable diagnostic modality for imaging anterior ocular structures. Its utility has been well studied in anterior segment, lenticular, and pars plicata pathologies. However, imaging of the pars plana has been seldom described. We present the case of a 66-year-old woman referred for vitreous hemorrhage after expulsive cannula dislodgement into the posterior segment during wound hydration at the end of cataract surgery. B-scan ultrasonography initially detected a very anterior abnormality, but the resolution was insufficient for accurate diagnosis...

Heterothermy, the ability to allow body temperature (Tb) to fluctuate, has been proposed as an adaptive mechanism that enables large ungulates to cope with the high environmental temperatures and lack of free water experienced in arid environments. By storing heat during the daytime and dissipating it during the night, arid-adapted ungulates may reduce evaporative water loss and conserve water. Adaptive heterothermy in large ungulates should be particularly pronounced in hot environments with severely limited access to free water...

A 30-year-old patient went to the emergency department because of a chemical burn to the left eye more than 10 days ago by toilet cleanser. Surprisingly, a small piece of glass was found in the inferior anterior chamber in the same eye. The visual acuity was counting fingers. There was conjunctival congestion, corneal oedema and Descemet's membrane striae. And there was also a corneal leukoma around 4 to 5 o'clock. Through repeated questioning he recalled that he was injured by an exploded light bulb around 21 years ago...

Autologous gastrointestinal tissue has remained the gold-standard reconstructive biomaterial in urology for >100 years. Mucus-secreting epithelium is associated with lifelong metabolic and neuromechanical complications when implanted into the urinary tract. Therefore, the availability of biocompatible tissue-engineered biomaterials such as extracellular matrix (ECM) scaffolds may provide an attractive alternative for urologists. ECMs are decellularised, biodegradable membranes that have shown promise for repairing defective urinary tract segments in vitro and in vivo by inducing a host-derived tissue remodelling response after implantation...
