To assess the repeatability and reproducibility of post-mortem central corneal thickness (CCT) measurements made by the portable iVue spectra-domain (SD) optical coherence tomography OCT (Optovue Inc, Fremont, CA) system in humans, and to prospectively establish the time-course of CCT after death. In a prospective multicenter setting, CCT measurements were obtained from 58 human eyes at the following 16 time-points after death: immediately (within 2 h), and at each hour by the next 17 h. The range of CCT values for each subject was determined and longitudinal data were used to illustrate the variation in open and close eye mode...

PURPOSE: To investigate the feasibility of ureteral reconstruction using lingual mucosa graft (LMG) and evaluate the histological changes of the engrafted LMG in beagles. METHODS: Twelve male beagle dogs were randomly divided into groups A, B and C (n = 4). A ventral ureteral defect was created by excising half of the ureteral wall. The length of the defect was 3 cm, 6 cm, and 10 cm in groups A, B, and C, respectively. The LMGs were harvested and employed to repair the ureteral defects in onlay fashion...

Background: Bladder duplication is a rare congenital urinary tract malformation, and very few cases reported in the worldwide. Case presentation: We reported a case of an incomplete bladder duplication diagnosed by Single photon emission computed tomography / computed tomography( SPECT/CT) in 65-yeas-old male with lung cancer. SPECT/CT resulted in a change of diagnosis compared to whole-body planar bone scintigraphy in a cancer patient with suspected bone metastasis. Bladder duplication is a rare anomaly. Conclusion: Usually, bladder duplication is diagnosed by ultrasound or Intra Venous Urography (IVU) ...

BACKGROUND: Some researchers have reported thatapplying compressioncloser to the maximum diameter of the left ventricle (Point_max.LV) isassociated with worse clinical outcomes, challenging its traditional position as optimum compression point (Point_optimum). By locatingthe mid-sternum (the actual compression site)in terms of Point_max.LV and its right ventricular equivalent (Point_max.RV),we aimed to determine its optimumhorizontal position associated with increased chances of returnofspontaneouscirculation (ROSC)...

Medullary Sponge Kidney (MSK) disease is a rare congenital malformation of the distal nephron where cystic dilatation is appreciable in the collecting ducts and renal papillae. Most cases of the malformation are thought to arise from a malfunction within neurotrophic factor and tyrosine kinase interactions. Presentation and prognosis are usually indolent; however, they include urinary tract infections (UTI), nephrolithiasis and nephrocalcinosis, distal renal tubular acidosis (dRTA) and hypocitraturia. With an insidious and asymptomatic onset, MSK is a difficult renal manifestation to both diagnose and treat...
