PURPOSE: To determine if the anterior choroid is involved in ocular change during the Valsalva manoeuvre (VM). MATERIALS AND METHODS: Fifty-three healthy volunteers aged 18-65 years with normal visual field test results and no history of intraocular pressure (IOP) exceeding 21 mm Hg were recruited. Anterior and posterior choroidal changes before and during VM were recorded by ultrasound microscope and swept-source optical coherence tomography, respectively. Parameters of the anterior segment included ciliary body thickness (CBT0), thickness of the choroid at a distance of 4 mm from the root of the iris (CT4), anterior placement of the ciliary body (APCB) and trabecular-ciliary angle (TCA)...

Despite being a posterior segment ocular surgery, pars plana vitrectomy (PPV) may also affect anterior segment parameters. We aimed to investigate anterior segment alterations following PPV using ultrasound biomicroscopy (UBM) to visualize the structural anatomy of the eye. In this study, we enrolled phakic patients undergoing PPV (as the sole procedure). The anterior chamber depth, crystalline lens anterior-posterior (AP) diameter, anterior chamber angle, ciliary body dimensions, and integrity of the ciliary zonules and posterior capsule were assessed using UBM before and at least 3 months after PPV...

BACKGROUND AND OBJECTIVES: Rectal prolapse is often repaired laparoscopically, frequently with the use of reinforcement material. Both synthetic and biologically derived materials reduce recurrence rate compared to primary suture repair. Synthetic mesh introduces potential complications such as mesh erosion, fibrosis, and infection. Urinary bladder matrix (UBM) represents a biologically derived material for reinforcement of rectal prolapse repair with the potential to improve durability without risks of synthetic materials...

BACKGROUND: China has the largest burden of primary angle-closure glaucoma (PACG) worldwide. The mechanism of the angle closure is complex and includes pupillary block and non-pupillary block. Currently, opinion is that laser peripheral iridotomy (LPI) alone is not sufficient to prevent disease progression. Laser peripheral iridoplasty (LPIP) is an alternative and effective way of widening the angle recess in eyes that are affected by primary angle closure (PAC). However, it is not known if greater benefit would be achieved using LPI plus LPIP for PAC with multiple mechanisms (MAC)...

BACKGROUND: After the US Food and Drug Administration issued a safety warning concerning vaginal mesh implants in 2008, their use in correction of pelvic floor defects have decreased in the United States (http://www.fda.gov/NewsEvents/Newsroom/PressAnnouncements/ucm479732.htm). However, we are still treating patients who have had complications associated with their use, rectovaginal fistulas (RVFs) being one of them. Rectovaginal fistulas are considered complex if greater than 2.5 cm, recurrent, associated with inflammatory bowel disease, or if they are proximal in location...

The processing of electroencephalograms (EEGs) is a growing field where mature speech processing techniques are able to rapidly progress development and understanding of the associated neuroscience. I-vectors and Joint Factor Analysis (JFA), along with their foundational universal background models (UBMs) have progressed to a level of understanding that makes them prime for transition to the EEG community. To prove the capability of these techniques they are tested against two contrasting EEG data sets, PhysioNet's EEG Motor Movement/Imagery Dataset and the Temple University Hospital EEG Corpus, to highlight the effectiveness of the techniques with minimal domain knowledge modifications...

A 59-year-old woman was seen by an ophthalmologist for blurred vision, ocular pain, headache, and nausea. She was diagnosed with acute primary angle closure (APAC) and successfully treated with medications. Using ultrasound biomicroscopy (UBM), engorged episcleral vein was observed and small uveal effusion was diagnosed after laser peripheral iridotomy (LPI). The uveal effusion disappeared and was again diagnosed by UBM together with anterior segment inflammation with ocular pain. Iritis caused by LPI after APAC might be a cause of uveal effusion in this specific case...
