SiRNA targeting EGFR effectively prevents posterior capsular opacification after cataract surgery. (3/20)

PURPOSE: We investigated the effect of epidermal growth factor receptor (EGFR) siRNA on human lens epithelium (HLE) cells and the development of posterior capsular opacity (PCO). METHODS: We designed EGFR siRNA and used it to knockdown the expression of EGFR in HLE cells. Cell proliferation was examined by 3-(4,5-Dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide (MTT), cell growth curve assay and cell cycle analysis. Next, we selected an adaptable concentration of recombinant epidermal growth factor (EGF) for stimulating the growth of HLE cells to further test the suppressive effect of siRNA. At last, we established the model of PCO in rats to further investigate whether knocking down EGFR would prevent the progression of PCO in vivo. RESULTS: The cell proliferation of EGFR siRNA group was apparently inhibited no matter in short or long term and cell cycle was arrested in G(1) phase. Over expression EGF cannot rescue the inhibition of EGFR siRNA on HLE cells and the proliferation activity in HLE cells greatly decreased when EGF-EGFR signal pathway blockaded. In vivo experiments, the extent of PCO of EGFR siRNA group is much lower than the control group. CONCLUSIONS: Our results demonstrate that EGFR siRNA can effectively inhibit the progression of PCO. Thus, siRNA targeting EGFR may provide a totally new way for preventing PCO or even cataract.  (+info)

The impact of capsulorhexis diameter, localization and shape on posterior capsule opacification. (5/20)

BACKGROUND: The aim of this study was to evaluate the impact of capsulorhexis diameter, localization and shape on posterior capsule opacification (PCO) development after cataract extraction with phacoemulsification. MATERIAL/METHODS: We retrospectively analyzed of 297 patients who underwent phacoemulsification and AcrySof SA60AT implantation. In a first group of 97 patients, 53 received small capsulorhexis (3.9 to 4.9 mm in diameter) and 44 patients received large capsulorhexis (5.0 to 5.9 mm in diameter). Another group of 99 patients was split into subgroups--66 patients whose capsulorhexis were centrally located and 33 patients whose capsulorhexis were paracentral. A third group of 101 patients was split into subgroups--a subgroup of 59 patients were classified as having a regularly rimmed capsulorhexis and a subgroup of 42 patients as having an irregularly rimmed capsulorhexis. At 6 months follow-up, PCO was classified as none, mild, moderate, or severe, depending on the number of quadrants involved. RESULTS: 86.79% of the patients with a small capsulorhexis had no or mild PCO (p<0.001), whereas, 68.18% of the patients with a large capsulorhexis experienced moderate or severe PCO; 89.4% of the patients with a central capsulorhexis had no or mild PCO (p<0.001), whereas, 75.75% of the patients with a paracentral capsulorhexis had moderate or severe PCO; 86.44% of the patients with a regularly rimmed anterior capsulorhexis had no or mild PCO (p<0.001); and 69.04% of the patients with an irregular capsulorhexis rim had moderate or severe PCO. CONCLUSIONS: A small capsulorhexis diameter, its central localization and regular shape result in less PCO following phacoemulsification.  (+info)

Zebularine suppresses TGF-beta-induced lens epithelial cell-myofibroblast transdifferentiation by inhibiting MeCP2. (6/20)

PURPOSE: Posterior capsular opacification (PCO) is a common long-term complication of modern cataract surgery. Remnant lens epithelial cells (LECs) undergo a myofibroblast transdifferentiation that is thought to be the initial step of PCO pathogenesis. The purpose of this study is to determine the effects of zebularine on transforming growth factor-beta (TGFbeta)-induced, LEC-myofibroblast transdifferentiation. METHODS: The expression levels of methyl CpG binding protein 2 (MeCP2) and alpha-smooth muscle actin (alpha-SMA) in human PCO membranes were evaluated by confocal microscopy. The role that MeCP2 played in TGFbeta2-induced alpha-SMA expression was analyzed by western blotting both before and after MeCP2 knockdown with MeCP2-specific siRNA. The effect of zebularine on MeCP2 expression was analyzed over time using a variety of dosages. The effect of zebularine on TGFbeta2-induced alpha-SMA expression was determined by western blot analysis. RESULTS: MeCP2 and alpha-SMA co-localized in human PCO membranes. When MeCP2 was depleted, TGFbeta2 could not induce alpha-SMA expression. Zebularine decreased MeCP2 expression in lens epithelial cells in a time- and dose-dependent pattern and reversed TGFbeta2-induced alpha-SMA expression. CONCLUSIONS: MeCP2 plays an important role in TGFbeta2-induced alpha-SMA expression in lens epithelial cells. Zebularine could reverse the TGFbeta2-induced alpha-SMA expression by inhibiting MeCP2 expression. Therefore, zebularine could potentially prevent PCO formation.  (+info)

Posterior capsule opacification (PCO) is a fairly common complication of cataract surgery. Sometimes you can develop a thickening of the back (posterior) of the lens capsule which holds your artificial lens in place.This thickening of the capsule causes your vision to become cloudy. If this happens you may need to have laser treatment to make vision clear again. Once you have had the laser treatment for PCO it doesnt normally cause any long term problem with your sight.

Purpose : Many drugs have been loaded onto IOLs by different methods to achieve a sustained and controlled release of drugs to treat posterior capsular opacification (PCO). This study tested the hypothesis that the sustained release of genistein (GEN) from negative charged nanoparticles surface modified IOL by ester bond can prevent the PCO in rabbit eyes effectively and safely.. Methods : Nanostructured lipid carriers (NLCs) loaded with GEN (GEN-NLC) were made by melt emulsification method. GEN-NLCs were attached on IOLs by ester bond formed by the dehydration between the carboxyl group offered by the sodium deoxycholate on the NLC surface and the hydroxy group of hydrophilic acrylic IOLs. The morphology and release of the GEN-NLC on the surface of IOLs and was measured. Sixty New Zealand albino rabbits undergoing phacoemulsification in left eye were randomly and equally divided into three groups. Group A: original IOL; group B: anterior chamber (AC) injection GEN-NLC and original IOL; group C: ...
Aslam and colleagues6 have presented, in the BJO, a systematic analysis of strategies to evaluate posterior capsule opacity and have pointed out that at present there is no entirely satisfactory method of comprehensively quantifying capsule opacity in vivo. In addition to regional quantitation of the optical density of capsule opacity, typically scored subjectively or by analysis of digitised photographs, capsule opacity has fibrotic and lens epithelial proliferative components that require three dimensional measurement. In order to assess the extent of opacification, researchers such as Sacu and colleagues have resorted to multiple modes of evaluation including a subjective score that ranks subtypes of fibrotic opacity, automated analysis of digitised photographs, and need for Nd:YAG laser capsulotomy.4 Hayashi and Hayashi7 have argued that multiple methods are indeed required to adequately describe these various features, and have suggested that retroillumination photography is helpful in ...
Injury to lens epithelial cells (LECs) leads to epithelial-mesenchymal transition (EMT) with resultant fibrosis. The tropomyosin (Tpm) family of cytoskeleton proteins is involved in regulating and stabilizing actin microfilaments. Aberrant expression of Tpms leads to abnormal morphological changes with disintegration of epithelial integrity. The EMT of LECs has been proposed as a major cause of posterior capsule opacification (PCO) after cataract surgery. Using in vivo rodent PCO and human cataractous LECs, we demonstrated that the aberrant expression of rat Tpm and human Tpm1α/2β suggested their association in remodelling of the actin cytoskeleton during EMT of LECs. Expression analysis from abnormally growing LECs after lens extraction revealed elevated expression of α-smooth muscle actin (α-SMA), a marker for EMT. Importantly, these cells displayed increased expression of Tpm1α/2β following EMT/PCO formation. Expression of Tpm1α/2β was up-regulated in LECs isolated from cataractous ...
Purpose : The goal of this research is to develop polymers to prevent posterior capsule opacification (PCO) by inhibiting adhesion of lens epithelial cells (LECs). PCO is the most common complication of cataract surgery, reported in as many as half of all patients 2-5 years after surgery. Previous studies demonstrate conflicting evidence about the impact of intraocular lens (IOL) hydrophilicity on LEC adhesion. These conflicting reports indicate that there is likely an optimal intermediate surface energy, or that there may be another factor in addition to surface energy that is influencing LEC response. This study seeks to determine both the chemical and mechanical factors that influence LEC adhesion and proliferation. Methods : A series of amphiphilic polymers covering a range of surface energies ranging from very hydrophilic to very hydrophobic were synthesized by free radical copolymerization. The monomers used in designing the amphiphilic polymers have been used previously in ophthalmic ...

Cataracts are a degenerative change of the lens, resulting in an opacity and interference with optical clarity and vision. Cataracts are the most common cause of blindness in dogs. Surgical removal of the cataract and replacement with an artificial intraocular lens implant (IOL) restores vision. The leading complication of cataract surgery in dogs and humans is posterior capsular opacification (PCO), a hazy opacity of the lens capsule developing post-operatively that results in diminished vision. This is treated with laser surgery in humans which cannot be performed in dogs. Therefore, an alternative method for preventing or decreasing PCO must be found. A capsular tension ring (CTR) is a device that can be placed within the lens capsule, with the IOL, at the time of cataract surgery. Previous studies in humans have shown that CTRs significantly decrease PCO formation. We hypothesize that CTRs will significantly diminish PCO formation in canine lenses using an ex vivo model and in clinical canine

The pathological development of lens epithelial cells (LECs) leads to posterior capsular opacification (PCO). This studywas undertaken to investigate the effects of microRNA-486-5p (miR-486-5p) on TGF-b2-induced proliferation, invasionand epithelial-mesenchymal transition (EMT) in the lens epithelial cell line SRA01/04, and to explore the underlyingmolecular mechanisms. The expression of miR-486-5p in TGF-b2-induced SRA01/04 cells was down-regulated, and theexpression of Smad2, p-Smad2 and p-Smad3 was up-regulated. A dual-luciferase reporter assay revealed that miR-486-5pdirectly targets the 30-UTR of Smad2. MiR-486-5p mimic transfection markedly down-regulated the expression levels ofSmad2, thus inhibiting the expression of p-Smad2 and p-Smad3. MiR-486-5p overexpression in SRA01/04 cells markedlysuppressed TGF-b2-induced proliferation and invasion, inhibited protein expression of CDK2 and CDK4, down-regulatedfibronectin, a-SMA and vimentin and up-regulated E-cadherin; these effects were partly ...

Cataract surgery is a very common procedure with low risks involved. Less than a single percent of patients will suffer from any serious complications that will necessitate further surgeries. If complications do arise, these are, more often than not, successfully treated through additional procedures.. While it is possible that your vision may get worse or that permanent damage may occur after the cataract surgery, these cases are extremely rare. Still, a comprehensive consultation with your eye doctor should be done so that you will be fully informed of all the possible risks.. Posterior Capsule Opacification. The most common risk that a cataract patient may encounter after surgery is the development of a condition called posterior capsule opacification, or PCO. In this condition, a portion of the capsule of your lens may thicken and lead to a cloudy vision. While some may mistake this as a sign of the cataract returning, it is actually cells growing at the back of the artificial lens.. This is ...
0024]Typically the human lens capsule of the present invention may be supported on a solid substrate such as a plastics or glass surface, e.g. the surface of a petri dish. Sigma ligands may be first identified as such by conducting, for example, a radioligand binding assay, such as described in WO 00/00599 to ascertain that the test agent is a sigma ligand, before carrying out the method as described above. Importantly, sigma radioligand binding assays determine only that an agent binds to sigma sites and not whether it acts as an agonist or antagonist in functional terms (whether it acts to stimulate or inhibit the receptor). In WO 00/00599 it was disclosed that different sigma receptor subtypes--or even binding pockets on the same receptor molecule--can act in opposite ways to either promote or suppress apoptosis (cell death). Given that a number of sigma ligands bind to both sigma-1 and sigma-2 sites (that act in opposition to regulate cell death), the balance of their functional activities ...
Six rabbits underwent phacoemulsification with bilater implantation of an IOL. Postoperative power adjustment was performed using the femtosecond laser 2 weeks following implantation, in one eye. The animals were then followed clinically with slit lamp examination for an additional 4 weeks. The rabbits were then euthanized and the globes were enucleated. The globes were bisected coronally and gross examination and photographs from the posterior aspect were performed to assess anterior capsular opacification and fibrosis as well as posterior capsular opacification. After IOL explantation for power measurements, the globes were sectioned and processed for light microscopy following H&E staining ...

Glycans are essential regulators of protein function and are now in the focus of research in many physiological and pathophysiological processes. There are numerous modes of regulating their biosynthesis, including epigenetic mechanisms implicated in the expression of glyco-genes. Since N-glycans located at the cell membrane define intercellular communication as well as a cellular response to a given environment, we developed a method to preferentially analyze this fraction of glycans. The method is based on incorporation of living cells into polyacrylamide gels, partial denaturation of membrane proteins with 3 M urea and subsequent release of N-glycans with PNGase F followed by HPLC analysis. Using this newly developed method, we revealed multiple effects of epigenetic inhibitors Trichostatin A, sodium butyrate and zebularine on the composition of N-glycans in human cells. The induced changes were found to be reversible after inhibitor removal. Given that many epigenetic inhibitors are currently

Sinorhizobium fredii contains a second suboperon that appears homologous to the eryR-tpiB-rpiB suboperon in the erythritol locus (Figure 1). The TpiB amino acid sequence was used as a. representative of this suboperon to construct a phylogenetic tree. The BI 2536 nmr branch corresponding to the TpiB encoded outside of the erythritol locus is highlighted in red. The tree was constructed using ML and Bayesian analysis.

Ideally, the capsulorhexis diameter should be slightly smaller than the optic diameter so that we can achieve 360° overlap. But what if it doesnt? Well, it turns out that it is not that big of an issue because the capsule shrink-wraps in the post-op period and it makes the capsulorhexis diameter about 10% smaller --…
UFE treats all uterine fibroids at the same time and is, therefore, an extremely effective, all encompassing treatment option. I have 4.5cm,3.8cm fibroid on posterior wall myometrial uterus,I have heavy bleeding and the duration between periods nearly 15 days. Uterine what to do about fibroids after menopause are non-cancerous growth of the uterus that often appears during childbearing years. I was referred to Dr Parker for a second opinion after having an unsuccessful fibroid surgery and being told I needed a more invasive one to ever have a chance of conceiving. Other Medical Conditions Systemic lupus erythematosus, diabetes, pelvic inflammatory disorder, cirrhosis, and thyroid disorders can cause heavy bleeding.
Males 44-64 mm SVL; females 46-74 mm SVL (Wright and Wright 1949). This species resembles Rana pipiens and Rana onca; R. fisheri can be distinguished by more reduced dorsal/head spotting and shorter legs than R. onca, which in turn has smaller and fewer spots and shorter legs than R. pipiens (Linsdale 1940). Heel of extended hind limb falls considerably short of snout tip (Stejneger 1893). Tympanic disc has vertical diameter greater than the distance between the nostrils and eye (Stejneger 1893). Vomerine teeth between choanae and projecting beyond choanae posteriorly (Stejneger 1893). Hind feet about 2/3 webbed (Stejneger 1893). Single small metatarsal tubercle (Stejneger 1893). Paired weak dorsolateral ridges, and lacking longitudinal folds between the dorsolateral ridges (Stejneger 1893). Skin is granular on posterior lower aspect of femur (Stejneger 1893). Dorsum and flanks with numerous small dark spots "surrounded by lighter" (Stejneger 1893). No black ear patch (Stejneger 1893). Although ...
Calculation of selected torso asymmetry indices. (a) Cross-sections were cut through the torso surface model. PSIS axis=line joining skin markers on posterior superior iliac spines. (b) The quasi-Cobb angle (θ) was computed for each index of asymmetry between the most appropriate pair of points of inflection on the index-curve. (c) Angles of principal axis (PAX) rotation (θ1), back surface rotation (BSR, θ2), and the difference between BSR and PAX rotation (θ3) were recorded relative to the PSIS axis along with the "rib hump" (dL-dR). (d) Half-areas were cut relative to the PAX reference axis. Asymmetry of half-centroids CL and CR was measured in the antero-posterior (dXC) and lateral (ZCL vs. ZCR) directions. The angle of rotation of the line joining the half-centroids (θ), and the difference between aspect ratios (dAP/dLat) between left and right half-areas were also computed ...

Posterior capsule opacity (PCO) is the most common complication associated with cataract surgery. Fortunately, theres a relatively simple correction.
Genetic diversity within species may promote resilience to environmental change, yet little is known about how such variation is distributed at broad geographic scales. Here we develop a novel Bayesian methodology to analyse multi-species genetic diversity data in order to identify regions of high or low genetic diversity. We apply this method to co-distributed taxa from Australian marine waters. We extracted published summary statistics of population genetic diversity from 118 studies of 101 species and | 1000 populations from the Australian marine economic zone. We analysed these data using two approaches: a linear mixed model for standardised data, and a mixed beta-regression for unstandardised data, within a Bayesian framework. Our beta-regression approach performed better than models using standardised data, based on posterior predictive tests. The best model included region (Integrated Marine and Coastal Regionalisation of Australia (IMCRA) bioregions), latitude and latitude squared. Removing

A surface treated intraocular lens implant for use in the replacement of a cataractous natural lens to prevent posteriror capsular opacification. The surface treated intraocular lens includes one or more proteins, polypeptides, polyamino acids or polyamines bound to the surface of the intraocular lens implant covalently, non-covalently or a combination thereof. The one or more proteins, polypeptides, polyamino acids or polyamines present on the surface of the intraocular lens implant serves to reduce or eliminate residual lens epithelial cell migration within the lens capsule. By preventing residual lens epithelial cell migration, posterior capsular opacification of the intraocular lens implant is thus reduced or eliminated.
PURPOSE To evaluate whether cataract surgery in children should be performed with anterior vitrectomy and to examine the properties of the AcrySof SA30AL intraocular lens (IOL) in the pediatric eye. SETTING Filatov Institute, Odessa, Ukraine. METHODS Cataract surgery was performed in 66 children aged 3 to 15 years. They were randomized to surgery with or without anterior vitrectomy. All eyes were implanted with the single-piece AcrySof SA30AL IOL (Alcon). During the study, the patients who needed surgery for after-cataract had a second surgical procedure. Two years after surgery, the surgical method was evaluated using exact logistic regression. Also, the Evaluation of Posterior Capsule Opacification (EPCO) score was compared between the patients who had surgery for after-cataract and the patients who did not need this. The presence of posterior synechias and centration of the IOL were assessed. RESULTS Children in the younger age group (|/=62 months at surgery) had surgery for after-cataract more

Dental amalgam is the most thoroughly researched and tested dental material of all those in use today. Although it contains trace amounts of mercury (a known toxin), when this element is bound to other components of amalgam, it becomes safe for use. In 2006, government-funded studies further concluded that there is no evidence that dental amalgam causes brain injury or neurological problems in children. Similar supportive statements have been released by the Federal Drug Administration (FDA), National Institutes of Health (NIH), U.S. Public Health Service (USPHS), Centers for Disease Control (CDC) and World Health Organization (WHO), as well as the Alzheimers, Pediatric, Autism and Multiple Sclerosis Associations.. In fact, over 950 scientific and medical studies support amalgams unbeatable strength, safety and cost-effectiveness. The ADA Research Foundation also notes that it is the "strongest and most durable direct restoration for large load-bearing restoration on posterior ...
On the HRCT image, note the hazy increase in density of the lung parenchyma (blue arrows) in keeping with "ground-glass" opacification. Unlike "ground-glass" opacification on a chest radiograph, the ground-glass opacity on HRCT does not obscure the pulmonary vasculature. In this case, the presence of normal (yellow arrows) and abnormal lung (blue arrows) is easily appreciated, but it there is uncertainty as to the presence of ground-glass opacification, comparison of the attenuation of the lung parenchyma with air in the bronchi will aid detection - this is known as the "black bronchus" sign.. The mechanism behind the pattern of ground-glass opacification is due to the displacement of air. This may be due to a number of factors including airspace filling and/or interstitial thickening.. In this patient, who was immunocompromised due to HIV infection, the most likely diagnosis is that of infective pneumonia due to Pneumocystis jirovecii (formerly known as PCP pneumonia). ...

PURPOSE To evaluate the uveal and capsular biocompatibility of hydrophilic acrylic, hydrophobic acrylic, and silicone intraocular lenses (IOLs) in eyes with uveitis. SETTING Department of Ophthalmology, University of Vienna, Vienna, Austria. METHODS This prospective study comprised 72 eyes with uveitis and 68 control eyes having phacoemulsification and IOL implantation by 1 surgeon. Patients received 1 of the following IOLs: foldable hydrophilic acrylic (Hydroview, Bausch & Lomb), hydrophobic acrylic (AcrySof, Alcon), or silicone (CeeOn 911, Pharmacia). Postoperative evaluations were at 1, 3, and 7 days and 1, 3, and 6 months. Cell reaction was evaluated by specular microscopy of the anterior IOL surface and the anterior and posterior capsule reaction, by biomicroscopy. RESULTS Small round cell deposition was observed on all IOLs in the immediate postoperative period, especially in eyes with uveitis. This reaction decreased 3 to 6 months after surgery. Although the CeeOn 911 had a higher mean
Posterior capsular opacification (PCO) caused by proliferation of residual epithelial cells over the lens equator and onto the posterior lens capsule [1] is the leading cause of visual impairment and blindness after cataract surgery [2-4]. There are currently no effective means by which to eradicate the residual lens epithelial cells during the operation [5,6]. In spite of improvements in the basic research on development of cataracts, surgical techniques, and the material or the design of the intraocular lens, the incidence of PCO is still 8~34.3% in adults, and nearly 100% in children [7-10]. One new promising approach for treatment of PCO is a gene therapy system uses a so-called suicide gene, the herpes simplex virus type 1 thymidine kinase (HSV-tk) gene, and the anti-herpes nucleoside analog drug, ganciclovir (GCV) [11-13]. In this system, GCV is phosphorylated by HSV-tk into a deoxynucleotide analog that becomes incorporated into DNA during strand replacement in proliferating cells, where ...
We offer free Cataract seminars throughout the year with a Q&A session and one of the questions we hear often, is "Will my cataract ever return after I have it removed?" Many people are concerned about whether or not they will need to repeat cataract surgery on the same eye at a later date. Luckily, you can rest assured that you cannot get a cataract in the same eye after having cataract surgery. A cataract is the clouding of the eyes natural lens. In cataract surgery, the natural lens is removed and replaced with an artificial lens called an IOL. The new lens will not get cloudy. A small portion of cataract patients, experience a clouding of the lens capsule months or years after surgery. This occurs in the membrane or "sac" that used tohold the natural lens. This is called Capsular Opacification. Should this rare occurrence happen to you, it is easily treated by a YAG Laser Capsulotomy, a quick and painless procedure that can be done in our office in just a few minutes. If you have questions ...
Posterior Capsule Opacity is NOT a result of a complication during or from your cataract surgery. It is however an unavoidable after effect of cataract surgery. It is easily treated and the vision in most cases is restored; as long as there is no other associated ophthalmic pathology.. The natural lens in the eye that forms a cloudy image known as a cataract sits inside what is called a capsule . The capsule is elastic in form and shrinks tightly around the lens. During cataract surgery the lens is removed through a small incision in the front of the lens capsule and vacuumed out and the new intraocular lens is put in its place. The capsule then wraps around it neatly, avoiding the need for sutures. Inside the lens are epithelial cells that continue to grow at a minute rate from the time our eyes form as a foetus. During cataract surgery these cells are removed with the cloudy lens, however it is unavoidable that some of the microscopic cells may remain. It is these epithelial cells that form ...
Researchers have long been interested in whether particular temperamental traits in childhood connote risk for depressive disorders. For example, children characterized as having high negative emotionality (NE; sadness, fear, anger) and low positive emotionality (PE; anhedonia, listlessness, and lack of enthusiasm) are hypothesized to be at risk for depression. Few studies, however, have examined whether (and how) these two temperamental dimensions interact to confer risk. In a sample of 329 preschoolers, the present study addressed this question by examining the relation between PE and NE and asymmetry in resting EEG activity in frontal and posterior regions, which are putative biomarkers for depression. Using a laboratory battery to define temperament, we found an interaction of PE and NE on posterior asymmetry. Specifically, when PE was high, NE was associated with greater relative right activity. When PE was low, NE was not related to posterior asymmetry. These results were driven by ...
Thirty-one out of the 34 cases had brain MRI records. Three cases refused brain MRI because of low social economic status or no time to perform brain MRI due to their own schedule. In this study, brain MRI include brain MRIdiffusion, brain MRI, brain MRI-magnetic resonance angiography (MRA), and brain MRI-internal auditory canal (MRI-IAC). Brain MRI-diffusion is a commonly performed MRI sequence for evaluation of acute ischemic stroke, and is sensitive in detection of small and early infarcts. Brain MRI is also sensitive in detection of infarcts and can more exact assessment about pathologic lesions. MRA generates pictures of the arteries or aneurysms for evaluating abnormal narrowing or vessel wall dilatations. In this study, brain MRI-MRA means that brain MRI was performed with brain MRA, and brain MRI-IAC means the brain MRI focused on posterior fossa area. Seventeen cases performed brain MRI-diffusion, 4 cases performed brain MRI, 15 performed brain MRI-MRA, and 2 performed brain MRI-IAC. In ...
There is opacification of the left hemithorax. There is a shift of the heart and mediastinal structures (i.e. the trachea) toward the side of opacification. This eliminates pleural effusion, pneumonia and pulmonary edema as possibilities. A tension pneumothorax will displace the heart and mediastinal structures away from the side of the pneumothorax but it will not cause complete opacification of the opposite lung. In addition, there should be no lung markings visible in the hemithorax which contains the pneumothorax. If you look carefully, there is a missing rib on the left side. That indicates a thoracotomy has been performed, at which time the left lung was removed (pneumonectomy) for cancer treatment ...
