CONCLUSION SLFIO for anterior repositioning of the maxilla can prevent undesirable transverse soft tissue changes of the nose. With the move towards simulation based microsurgical training and emphasis on the declining usage of animal models, there is a need for an objective method to evaluate microvascular anastomosis in a non-living, simulated microsurgical training environment. Our aim was to create a validated assessment tool to evaluate the intimal surface of the end product to measure skills acquisition. The intimal surface of 200 anastomoses from 23 candidates and 2 experts were assessed using ImageJ to measure 4 parameters 1) distance between the distal insertion points, 2) distance between the proximal insertion points, 3) length of sutures placed, 4) number of axes. Using these parameters, a 9-component scoring system was produced based on the hypothesis of the ideal anastomosis having equidistance between the above parameters. The scoring system was devised based on population performance to give a maximum score of 100. The EPIA tool demonstrated its ability to differentiate between seniority from undergraduate to expert. Furthermore, predictive validity was shown by demonstrating skill acquisition between day 3 and 5 of the microsurgery course. The EPIA tool is a valid and feasible method to assess and provide feedback regarding the end product as an adjunct to current scoring systems in simulated microsurgery. RATIONALE & OBJECTIVE Hematuria is the most typical presentation of immunoglobulin A nephropathy (IgAN); however, its role in disease progression is still controversial. This study aimed to evaluate the association of hematuria and progression of IgAN. STUDY DESIGN Retrospective cohort study. SETTING & PARTICIPANTS A cohort of 1,333 patients with IgAN treated at a Chinese referral hospital with a median follow-up of 45 months. PREDICTORS Microhematuria was evaluated in fresh urine using a fully automated urine particle analyzer (automated method) and urine sediment examination by a skilled examiner (manual method). Hematuria was characterized as a time-varying attribute; namely, average hematuria level was calculated for every 6-month period for each patient during follow-up. Remission was defined as average red blood cell count ≤5/high-power field (manual method) or ≤28 red blood cells/μL (automated method) during the first 6 months of follow-up. OUTCOMES Composite event of 50% decline in estimated glomerulaonfounding. The predictive value of reductions in hematuria was not directly evaluated. CONCLUSIONS Level of hematuria was independently associated with kidney disease progression, whereas hematuria remission was associated with improved kidney outcomes in IgAN among patients with persistent proteinuria. Additionally, to monitor IgAN progression, automated methods to evaluate hematuria hold promise as a replacement for manual evaluation of urinary sediment. BACKGROUND Self-rated health (SRH) is arguably the most widely used generic health measurement in survey research. However, SRH remains a black box for researchers. In our paper, we want to gain a better understanding of SRH by identifying its determinants, quantifying the contribution of different health domains to explain SRH, and by exploring the moderating role of gender, age groups, and the country of residence. METHOD Using data from 61,365 participants of the fifth wave (2013) of the Survey of Health, Ageing and Retirement in Europe (SHARE) living in fifteen European countries, we explain SRH via linear regression models. The independent variables are grouped into five health domains functioning, diseases, pain, mental health, and behavior. Via dominance analysis, we focus on their individual contribution to explaining SRH and compare these contributions across gender, three age groups, and fifteen European countries. RESULTS Our model explains SRH rather well (R2 = .51 for females/.48 for males) with functioning contributing most to the appraisal (.20/.18). Diseases were the second most relevant health dimension (.14/.16) followed by pain (.08/.07) and mental health (.07/.06). Health behavior (.02/.01) was less relevant for health ratings. This ranking held true for almost all countries with only little variance overall. A comparison of age groups indicated that the contribution of diseases and behavior to SRH decreased over the life-course while the contribution of functioning to R2 increased. CONCLUSION Our paper demonstrates that SRH is largely based on diverse health information with functioning and diseases being most important. However, there is still room for idiosyncrasies or even bias. OBJECTIVE To evaluate arterial oxygenation during the first 4 postoperative hours in dogs administered different fractions of inspired oxygen (FiO2) during general anesthesia with mechanical ventilation. STUDY DESIGN Prospective, randomized clinical trial. ANIMALS A total of 20 healthy female dogs, weighing >15 kg and body condition scores 3-7/9, admitted for ovariohysterectomy. METHODS Dogs were randomized to breathe an FiO2 >0.9 or 0.4 during isoflurane anesthesia with intermittent positive pressure ventilation. The intraoperative PaO2FiO2 ratio was recorded during closure of the linea alba. Arterial blood was obtained 5, 60 and 240 minutes after extubation for measurement of PaO2 and PaCO2 (FiO2 = 0.21). Demographic characteristics, duration of anesthesia, PaO2FiO2 ratio and anesthetic agents were compared between groups with Wilcoxon tests. The postoperative PaO2, PaCO2, rectal temperature, a visual sedation score and events of hypoxemia (PaO2 0.9. OBJECTIVES The aim of this study was to assess the effect of a metal artifact reduction (MAR) algorithm and the adaptive image noise optimizer (AINO) optimization filter in the detection of peri-implant dehiscences with cone beam computed tomography (CBCT). STUDY DESIGN Nine implants (3 zirconium, 3 titanium, and 3 zirconium-titanium) were placed in 3 sheep heads. Dehiscences were created on the buccal and lingual/palatal surfaces. A total of 9 defects and 9 controls with no defects were evaluated by 3 observers. Each sheep head was scanned 5 times with 4 scan modes; (1) without MAR/without AINO; (2) with MAR/without AINO; (3) without MAR/with AINO; and (4) with MAR/with AINO. Receiver operating characteristic analysis and weighted kappa coefficients were used to calculate diagnostic efficacy and intra- and interobserver agreements for each implant type and scan mode. RESULTS For all implant types, dehiscences were most accurately detected when both MAR and AINO were applied (P ≤ .045). Detection of dehiscences was more accurate with titanium implants (P ≤ .040). There were no significant differences in agreement among and between the observers. CONCLUSIONS The use of both MAR and AINO enhanced the detection accuracy of artificially created dehiscences in proximity to implants. Their combined use is recommended for detecting peri-implant dehiscences. Methanol poisoning is often described in the literature, but not transdermal or inhalational poisoning. It usually involves variable multi-organ damage, among which visual, neurological, and gastrointestinal involvement, as well as the metabolic and electrolyte changes that can lead to death. Contact with toluene by occupational or intentional inhalation may also cause neurological abnormalities. This article describes the case of a female patient who was seen in the Emergency Department due to bilateral visual loss secondary to accidental poisoning (inhalation-transdermal) with a solvent containing methanol and toluene. She had a favourable outcome during admission after treatment with ethanol in perfusion and corticosteroids. Although retinal venous obstruction (RVO) has been primarily related to vascular risk factors and glaucoma, there are a few studies of RVO in patients with solid organ transplants. An analysis was performed on total of 331 patients who presented with RVO (branch RVO in 226 cases and central RVO in 105 cases) over a 10 year period, and the characteristics were compared with the 4 patients with a history of solid organ transplant (liver, renal, or bipulmonary) who presented with RVO. In this series, the onset of RVO in transplant patients occurred at earlier ages than in other patients with RVO (58 vs. 68 years, respectively), affected the central vein of the retina (100% vs. 32%), and was associated with diabetes mellitus (75% vs. 25%), as well as with steroidal (100% vs. 1%) and immunosuppressive (tacrolimus 75% vs. 0%) treatments. A report is presented on the visual and clinical results from a retrospective case series of patients with chronic, evaporative, dry eye syndrome (DES), after refractive surgery, and treated with intense pulsed light treatment (IPL). Four sessions were performed, and the Ocular Surface Disease Index (OSDI) questionnaire was completed before initiating treatment and after the last session. see more Pre- and post-treatment data included visual acuity (VA), refraction, clinical evaluation (DEWS severity grading, and Oxford corneal staining), and Orbscan topography. Twenty eyes were treated and the following data recorded SchirmerI 14.7±5.6; 15.6±3.4mm, tear breakup time (TBUT) 3.4±1.6; 5.1±1.2s (P>.003), DEWS 3.4±0.5; 1.6±0.7 (P.03). A significant clinical and visual improvement was observed, together with a decreased frequency in artificial tear use, in LASIK patients with chronic DES after IPL treatment. The case is reported of a 73-year-old male presenting with the recently described peripapillary pachychoroid syndrome. This syndrome is included in the pachychoroid diseases, which is a relatively new condition characterised by increased choroidal thickness with attenuation of the choriocapillary layer located above dilated choroidal vessels. It is associated with progressive malfunction of the retinal pigment epithelium and neovascularisation. The case is presented with a multimodal image, in which some tests show signs not previously described. In addition, a description is presented of the asymmetric outcome of both eyes after multiple treatments, since the left eye has a very severe affectation, and is refractory to the treatment. We present the case of a 3-year-old male child with an epibulbar bone choristoma. The patient presented with a hard consistency subconjunctival mass of 8×10mm in the superior-temporal quadrant of his right eye along with vascularisation and a long cilium of approximately 8 to 10mm that touched the corneal surface. The histopathology study showed the presence of trabeculae of mature, compact bone surrounded by fibrous tissue, as well as Havers channels with concentric rings of laminar bone without bone marrow, and with normal osteocytes which defined the diagnosis of epibulbar bone choristoma. Osseous choristoma is the rarest type of the ocular choristoma and should be considered as a differential diagnosis among paediatric epibulbar tumours. INTRODUCTION Renal transplantation (RT) has evolved to improve its functionality. Some factors have been little studied, one of which is hyperuricemia and its impact on renal graft function. The objective of this study is to determine the prevalence of complications of renal transplantation and its influence on hyperuricemia values in the first year of evolution. MATERIAL AND METHODS The authors completed a retrospective, observational study of 2 RT units in Mexico from January 2013 to December 2017. In total, 1009 files met the inclusion criteria; the levels of uric acid (UA) and creatinine (Cr) were determined before transplantation and in months 1, 3, 6, 9, and 12 after transplantation. Descriptive analysis was performed with measures of central tendency, measures of dispersion, difference of means with Student t test, and SPSS version 25 (IBM, Armonk, NY, United States). RESULTS The mean pretransplant UA was 6.24 mg/dL (standard deviation [SD] 1.97); per month was 4.73 mg/dL (SD 1.49). There is a difference in means between categorized groups of UA in the 5 post-RT moments (1, 3, 6, 9, and 12 months).
