  3. 急性原发性闭角型青光眼%Acute Primary Closed Angle Glaucoma(Abstract)

    2001-01-01

    Acute primary closed angle glaucoma is fast becoming one of the most important causes of blindness in the 21 st Century. World bhnding statistics show that there are 60 million people suffering from glaucoma. Of these,approximately 6 million are blind and 1.5 million (25%) are due to acute closed angle glaucoma. With the aging population, the number of patients blind from glaucoma will continue to increase.Attacks from acute primary closed angle glaucoma can lead to irreversible blindness to the affected eye.Blindness can be effectively prevented in acute primary closed angle glaucoma because the severity of symptoms will draw the attention of the patient who will then seek for medical care. Therefore, it is essential to educate the public,doctors and healthcare workers about the danger and symptoms of acute glaucoma. With early diagnosis and treatment to the affected eye and laser iridotomy to the fellow eye-bilateral blindness from acute glaucoma can be prevented.This paper highlights important clinical advances in the management of acute primary closed angle glaucoma and also poses several questions for discussion.(1) What evidence is there to suggest that bilateral blindness from acute primary closed angle glaucom is preventable?(2) In what way is Ultrasonic Biomicroscopy (UBM) useful in clinical research in glaucoma?(3) Will UBM be important in clinical diagnosis in primary closed angle glaucoma?(4) What is the scientific basis of treatment in acute primary closed angle glaucoma?(5) What are the essential procedures to preserve vision in chronic primary closed angle glaucoma?(6) What are the reasons for blindness after laser iridotomy?(7) What is the mechanism of laser iridoplasty?(8) What are the reasons why laser iridoplasty should be combined with laser iridotomy?(9) Why there is an intraocular pressure increase in 50% of eyes within 3 months after laser iridoplasty?(10) Can UBM explain the changes in the angle after lens removal in primary closed angle

    Full Text Available Background: Acute primary angle closure (APAC is one of the causes of blindness in Department of Ophthalmology Cipto Mangunkusumo General Hospital. Management of APAC is still controversial. Laser peripheral iridotomy is difficult to be done due to corneal edema as a result of persistent high intraocular pressure (IOP. It is believe that paracentesis will lower IOP immediately. The objective of the study was to assess outcome of paracentesis as the initial management in Malay Indonesian eyes with APAC.Methods: This intervention study was conducted at the Eye Clinic of Cipto Mangunkusumo Hospital and Jakarta Eye Center commencing in January 2005 until December 2007. Malay Indonesian eyes with APAC were included in this study in accordance with the new Asia Pacific consensus. All APAC eyes underwent paracentesis to lower IOP. The presenting and post-paracentesis IOP and peripheral anterior synechiae were noted. The outcome was termed as good when IOP was ≤ 21 mmHg and poor when IOP was > 21 mmHg.Results: A total of 45 APAC eyes were recruited. Thirty-eight of these belonged to women; mean age was 54.6 ± 1.56 years. Meanwhile, average duration of symptoms was 13.15 ± 7.4 days and mean of extent of peripheral anterior synechiae (PAS was 7.7 ± 3.1 hours. There was a strong correlation regarding duration of symptoms to the formation of PAS (r = 0.672; p < 0.001. The mean presenting IOP was 55 ± 13.37 mmHg and mean post-paracentesis IOP was 27 ± 12.78 mmHg. A decrease of 49% in IOP ( p < 0.001 was observed after paracentesis with good outcome in 19 eyes and poor outcome in 26 eyes.Conclusion: Paracentesis as an initial intervention in APAC eyes reduces the IOP immediately, but only as a temporary response.

    Primary angle closure disease (PACD), prevalent in Asian countries, is generally associated with a shallower anterior chamber, a shorter axial length, thicker lens, hyperopia, and female sex. Other physiologic factors, however, may be important, especially with regard to triggering acute primary angle closure. Thickening of the choroid has been demonstrated in untreated and treated, acute and chronic PACD eyes. Recently, there has been growing interest in studying the role of the choroid in the pathophysiology of PACD. The emergence of new imaging technology such as the enhanced depth imaging mode of spectral-domain optical coherence tomography and swept-source optical coherence tomography has contributed to understanding PACD pathologies. We summarize the functions of the choroid and choroidal changes in the pathogenesis of PACD, and discuss potential future developments. PMID:26164737

    Full Text Available Aim: To provide a synopsis of primary angle closure disease in India, and Indian studies on the same. Results: Primary angle closure glaucoma forms almost half of all adult primary glaucomas seen in a hospital setting in India. Anatomically, corneal diameters and anterior chamber depths were least in acute and chronic PACG eyes as compared to subacute eyes and controls. Besides relative pupillary block, a Valsalva maneuver during activities of daily living may be responsible for intermittent angle closure and raised IOP in predisposed eyes. Iridotomy alone, controlled the intraocular pressure in 66.7% of subacute eyes and 12.9% of the acute. Medical therapy was additionally required for 35.5% of the acute eyes, 12.1% of the subacute and 30.0% of the chronic cases. There was a greater mean and peak IOP reduction, achieved with 0.005% latanoprost once daily, 8.2 ± 2.0 mm Hg, compared with 0.5% timolol twice daily, 6.1 ± 1.7 mm Hg2. A progression of PACS to PAC was seen in 22%, PAC to PAC OHT in 38.7% and PAC OHT to PACG in 30.7% over 5 years. Conclusions: Primary angle closure disease is common in India, and can be managed well with iridotomy, followed by an appropriate control of IOP.

    Primary angle-closure glaucoma is potentially a devastating disease, responsible for half of glaucoma-related blindness worldwide. Angle closure is characterized by appositional approximation or contact between the iris and trabecular meshwork. It tends to develop in eyes with shallow anterior chambers, anteriorly positioned or pushed lenses, and angle crowding. Risk of primary angle-closure glaucoma is high among women, the elderly and the hyperopic, and it is most prevalent in Asia. Investigation into genetic mechanisms of glaucoma inheritance is underway. Diagnosis relies on gonioscopy and may be aided by anterior segment optical coherence tomography and ultrasound biomicroscopy. Treatment is designed to control intraocular pressure while monitoring changes to the angle and optic nerve head. Treatment typically begins with medical management through pressure-reducing topical medications. Peripheral iridotomy is often performed to alleviate pupillary block, while laser iridoplasty has been found effective for mechanisms of closure other than pupillary block, such as plateau iris syndrome. Phacoemulsification, with or without goniosynechialysis, both in eyes with existing cataracts and in those with clear lenses, is thus far a viable treatment alternative. Long-term research currently underway will examine its efficacy in cases of angle closure in early stages of the disease. Endoscopic cyclophotocoagulation is another treatment option, which can be combined with cataract surgery. Trabeculectomy remains effective therapy for more advanced cases. PMID:26119516

    Full Text Available Abstract Background Acute angle-closure glaucoma is a rare complication in patients receiving anti-depressant treatment. In the following case, we report the development of acute angle closure glaucoma in a patient who overdosed on Citalopram, an antidepressant, and discuss the possible etiological mechanisms for the condition. Case presentation We report a 54 year old, Caucasian lady, with depression and alcohol dependence syndrome, who developed acute angle-closure glaucoma after an overdose of Citalopram, along with alcohol. She was treated with medications and had bilateral Yag laser iridotomies to correct the glaucoma and has made complete recovery. In this case, the underlying cause for glaucoma appears to be related to the ingestion of Citalopram. Conclusion The patho-physiological basis for acute angle closure glaucoma in relation to antidepressant medications remains unclear. The authors suggest Citalopram may have a direct action on the Iris or Ciliary body muscle through serotonergic or anti-cholinergic mechanisms or both. This case highlights the importance of the awareness of the underlying risks, which may predispose an individual to develop acute angle-closure glaucoma, and reminds the clinicians the significance of history taking and examination of the eye before and after starting anti-depressants. This area needs to be further researched.

    Full Text Available Background: The primary open-angle glaucoma is a problem for public health all over the world. It is a silent and slowly progressive disease leading to blindness. In most patients this can be prevented if the risk factors leading to the disease are detected in time. Objective: To describe some epidemiological factors of patients with primary open-angle glaucoma. Methods: Clinical, epidemiological, prospective and longitudinal study in patients with primary open-angle glaucoma who attended the glaucoma consultation of the Provincial General University Hospital "Dr. Gustavo Aldereguía Lima" of Cienfuegos, from January to February 2009. The following variables were analyzed: age, sex, family and personal medical history, toxic habits and time of diagnosis of the disease. Results: There was prevalence of primary open-angle glaucoma (87, 5% mostly in females (53, 6% and patients over 61 years old as well as in white skinned patients (52 and 62% respectively. Hypertension was the leading entity referred to as pathological personal and family antecedent (62 and 42% respectively. Glaucoma and myopia predominated as previous eye history. The most frequent toxic habits were the consumption of more than 2 cups of coffee a day (53% and smoking (32%. The largest amount of patients had more than 5 years evolution of the disease.

    Objective To determine longitudinal changes in angle configuration in the eyes of primary angle-closure suspects (PACS) treated by laser peripheral iridotomy (LPI) and in untreated fellow eyes. Design Longitudinal cohort study. Participants Primary angle-closure suspects aged 50 to 70 years were enrolled in a randomized, controlled clinical trial. Methods Each participant was treated by LPI in 1 randomly selected eye, with the fellow eye serving as a control. Angle width was assessed in a masked fashion using gonioscopy and anterior segment optical coherence tomography (AS-OCT) before and at 2 weeks, 6 months, and 18 months after LPI. Main Outcome Measures Angle width in degrees was calculated from Shaffer grades assessed under static gonioscopy. Angle configuration was also evaluated using angle opening distance (AOD250, AOD500, AOD750), trabecular-iris space area (TISA500, TISA750), and angle recess area (ARA) measured in AS-OCT images. Results No significant difference was found in baseline measures of angle configuration between treated and untreated eyes. At 2 weeks after LPI, the drainage angle on gonioscopy widened from a mean of 13.5° at baseline to a mean of 25.7° in treated eyes, which was also confirmed by significant increases in all AS-OCT angle width measures (P<0.001 for all variables). Between 2 weeks and 18 months after LPI, a significant decrease in angle width was observed over time in treated eyes (P<0.001 for all variables), although the change over the first 5.5 months was not statistically significant for angle width measured under gonioscopy (P = 0.18), AOD250 (P = 0.167) and ARA (P = 0.83). In untreated eyes, angle width consistently decreased across all follow-up visits after LPI, with a more rapid longitudinal decrease compared with treated eyes (P values for all variables ≤0.003). The annual rate of change in angle width was equivalent to 1.2°/year (95% confidence interval [CI], 0.8–1.6) in treated eyes and 1.6°/year (95% CI, 1

    Full Text Available Escitalopram is an antidepressant of the selective serotonin reuptake inhibitor(SSRI class. In this manuscript, we report the case of a female patient who developed bilateral acute angle-closure glaucoma induced by escitalopram. A 46-year-old female patient was admitted to our ophthalmology clinic with complaints of severe pain around the both eyes, headache, nausea, and vomiting for two days. In her past medical history, she was using escitalopram for depression for two years. Visual acuity was at hand movement level in both eyes. Anterior segment examination showed bilateral diffuse conjunctival hyperemia, corneal edema, shallow anterior chamber, and fixed dilated pupils. Intraocular pressure was 47 mmHg in the right and 68 mmHg in the left eye. The diagnosis was acute angle-closure glaucoma, and the escitalopram medication was discontinued. She was treated with topical and systemic antiglaucomatous medication. After the cornea become clear, bilateral peripheral laser iridotomy was done. In the following year, she did not begin escitalopram medication again and no other acute angle-closure attack was seen. (Turk J Ophthalmol 2014; 44:396-9

  2. Argon laser trabeculoplasty as primary therapy in open angle glaucoma

    To determine the effect of Argon Laser Trabeculoplasty (ALT) as a primary mode of therapy in reducing the intraocular Pressure (IOP) of patients diagnosed with Primary Open Angle Glaucoma (POAG). A total of 35 eyes of 35 patients with the gender distribution of 27 men and 8 women who were newly diagnosed with POAG, were included in this study. Mean age of the patients was 55.2 years with the range of 32 to 76 years. All of them were treated with argon laser trabeculoplasty as a primary mode of therapy. Intra ocular pressure was measured objectively using Goldman applanation tonometer, pre-and-post laser therapy. The pre-laser mean IOP was 27.63 mmHg (range 21-40 mmHg). The post-laser mean IOP measured at 6 months follow up was 15.5 mmHg (range 11 - 33 mmHg) with mean decrease of 12.1 mmHg. The decrease in IOP was seen in 32 eyes (95%) with no change observed in 3 (5%) eyes. The result shows a marked decline in IOP in patients with POAG who underwent ALT as a primary mode of treatment. Further studies with large sample size and longer follow-up will help in making future recommendations. (author)

  3. Association of Matrix Metalloproteinase-9 (MMP9) Variants with Primary Angle Closure and Primary Angle Closure Glaucoma

    Wiggs, Janey L.; Pasquale, Louis R.; Sun, Xinghuai; Fan, Bao Jian

    2016-01-01

    Shorter axial length observed in patients with primary angle closure glaucoma (PACG) might be due to altered matrix metalloproteinase-9 (MMP9) activity resulting in ECM remodeling during eye growth and development. This study aimed to evaluate common variants in MMP9 for association with PACG. Six tag SNPs of MMP9 were genotyped in a Chinese sample of 1,030 cases, including 572 PACG and 458 primary angle closure (PAC), and 499 controls. None of 6 SNPs were significantly associated with overall PAC/PACG (P > 0.07) or with PAC/PACG subgroups (Pc > 0.18). Meta-analysis of two non-Chinese studies revealed significant association between rs17576 and PACG (ORs = 0.56, P 0.47). The largest association study to date did not find significant association between MMP9 and PAC/PACG in Chinese; meta-analysis with other Chinese datasets did not produce significant association. In most instances combination with non-Chinese datasets was not possible except for one variant showing nominally significant association. More work is needed to define the role of MMP9 variants in PACG. PMID:27272641

  5. Molecular complexity of primary open angle glaucoma: current concepts

    Kunal Ray; Suddhasil Mookherjee

    2009-12-01

    Glaucoma is a group of heterogeneous optic neuropathies with complex genetic basis. Among the three principle subtypes of glaucoma, primary open angle glaucoma (POAG) occurs most frequently. Till date, 25 loci have been found to be linked to POAG. However, only three underlying genes (Myocilin, Optineurin and WDR36) have been identified. In addition, at least 30 other genes have been reported to be associated with POAG. Despite strong genetic influence in POAG pathogenesis, only a small part of the disease can be explained in terms of genetic aberration. Current concepts of glaucoma pathogenesis suggest it to be a neurodegenerative disorder which is triggered by different factors including mechanical stress due to intra-ocular pressure, reduced blood flow to retina, reperfusion injury, oxidative stress, glutamate excitotoxicity, and aberrant immune response. Here we present a mechanistic overview of potential pathways and crosstalk between them operating in POAG pathogenesis.

  6. Primary open-angle glaucoma: everyone’s business

    2012-01-01

    Full Text Available Primary open-angle glaucoma (POAG is sometimes called the ‘thief of sight’. There is no pain or discomfort, and vision loss is so gradual that people often do not notice it.POAG cannot be cured: it requires ongoing treatment for the remainder of a patient’s life. Blindness from POAG also cannot be reversed, but it can be prevented if the disease is diagnosed early and treated. Effectively addressing POAG therefore requires the careful involvement of many different people, including health workers, the patient, non-clinical staff, and health planners.As eye care practitioners, we must do more than merely diagnose and treat people with POAG; we must gain the trust of patients and show them that we are there to help.

    Full Text Available Gabriel Beidoe, Shaker A MousaPharmaceutical Research Institute at Albany College of Pharmacy and Health Sciences, Rensselaer, NY, USAAbstract: Primary open-angle glaucoma (POAG is a leading cause of blindness with no known cure. Management of the disease focuses on lowering intraocular pressure (IOP with current classes of drugs like prostaglandin analogs, beta-blockers, alpha-agonists, and carbonic anhydrase inhibitors. These treatments have not helped all patients. Some patients continue to experience deterioration in the optic nerve even though their IOPs are within the normal range. New views have surfaced about other pathophysiological processes (such as oxidative stress, vascular dysfunction, and retinal cell apoptosis being involved in POAG progression, and adjunctive treatments with drugs like memantine, bis(7-tacrine, nimodipine, and mirtogenol are advocated. This review examines the current and proposed treatments for POAG. Some of the proposed drugs (bis(7-tacrine, nimodipine, vitamin E, and others have shown good promise, mostly as monotherapy in various clinical trials. It is recommended that both the current and proposed drugs be put through further robust trials in concurrent administration and evaluated.Keywords: bis(7-tacrine, betaxolol, memantine, mirtogenol, POAG, timolol, travoprost

  10. Do we really need to panic in all acute vision loss in ICU? Acute angle-closure glaucoma.

    Akal, Ali; Kucuk, Ahmet; Yalcin, Funda; Yalcin, Saban

    2014-08-01

    Acute angle closure glaucoma is a sight-threatening situation characterized by a sudden and marked rise in intraocular pressure (IOP) due to obstruction of aqueous humour outflow. Many local (ocular drops, nasal and nebulized agents) and systemic drugs (e.g. atropine, adrenaline, ephedrine, some psychoactive and antiepileptic drugs) that are widely used in intensive care units have the potential to precipitate such an acute attack. In this case report, we describe progressive visual loss due to acute angle-closure glaucoma (AACG) in a 59 year old female patient followed in the ICU due to a massive pulmonary embolism.

  12. Epidemiological Properties of Primary Open Angle Glaucoma in Nigeria

    Lawan Abdu

    2013-01-01

    Full Text Available Background. Primary open angle glaucoma (POAG is progressive chronic optic neuropathy in adults in which intraocular pressure (IOP and other currently unknown factors contribute to damage. POAG is the second commonest cause of avoidable blindness in Nigeria. Pattern of Presentation. POAG is characterized by late presentation. Absence of pain which is a driving force for seeking medical help, inadequacy of trained eye care personnel, paucity of facilities, misdistribution of resources, lack of awareness, poor education, and poverty may all contribute to this. Medical and surgical treatment options available are challenging and tasking. Screening for Glaucoma. Screening is the presumptive identification of unrecognized disease (POAG by applying test(s which can be applied rapidly. Such test(s should be of high reliability, validity, yield, acceptable, and cost effective. The test should ideally be sensitive, specific, and efficient. It is difficult to select a suitable test that meets these criteria. Intraocular pressure (IOP appears to be the easiest option. But, high IOP is not diagnostic nor does normal value exclude the disease. Health education is a possible strategy in early case detection and management. Treatment of POAG. Glaucoma treatment can either be medical or surgical (this includes laser. Considering unavailability, potency, cost, and long-term effects of medication, surgery (trabeculectomy could be a better option. Laser trabeculoplasty is available in a few centers. Viscocanalostomy is not routinely performed. Patient education is vital to success as management is for life. Conclusion. POAG remains a cause of avoidable blindness in Nigeria. There is need for long-term strategy to identify patients early and institute prompt management. Improvement in training of eye care personnel and provision of up to date equipment is essential in achieving this goal.

    2013-01-01

    Full Text Available Purpose: To evaluate the effect of cataract surgery on intraocular pressure (IOP in filtered eyes with primary angle closure glaucoma (PACG. Methods: In this prospective interventional case series, 37 previously filtered eyes from 37 PACG patients with mean age of 62.1±10.4 years were consecutively enrolled. All patients had visually significant cataracts and phacoemulsification was performed at least 12 months after trabeculectomy. Visual acuity, IOP and the number of glaucoma medications were recorded preoperatively, and 1, 3, 6 and 12 months after surgery. Anterior chamber (AC depth was measured preoperatively and 3 months after cataract surgery with A-scan ultrasonography. The main outcome measure was IOP at 12 months. Results: IOP was decreased significantly from 18.16±5.91 mmHg at baseline to 15.37±2.90 mmHg at final follow-up (P<0.01. The mean number of glaucoma medications was significantly decreased from 1.81±0.24 to 0.86±1.00 (P=0.001 at 1 year postoperatively. At final follow up, 36 (97.2% eyes and 32 (86.4% eyes had IOP≤21 and IOP≤18 mmHg, respectively; 14 (37.8% eyes and 9 (24.3% eyes had IOP≤21 and IOP≤18 mmHg without medications, respectively. The magnitude of IOP reduction was correlated with higher preoperative IOP (r=0.85, P<0.001, shallower preoperative AC depth (r=-0.38, P=0.01 and greater changes in AC depth (r=-0.39, P=0.01. Conclusion: Cataract surgery reduces IOP and the number of glaucoma medications in previously filtered PACG eyes. This reduction seems to be greater in patients with higher preoperative IOP and shallower anterior chambers.

  8. A Rare Cause of Acute Abdominal Pain: Primary Appendagitis Epiploica

    Tarkan Ergun

    2014-03-01

    Primary appendagitis epiploica – one of the causes of acute abdominal pain – is a self-limited rare benign inflammatory condition involving the colonic epiploic appendages. Their therapy is conservative and clinically mimics other conditions requiring surgery such as acute diverticulitis or appendicitis. However, being a quite rare condition is the reason they are usually neglected by both the surgeon and the radiologist. However the computed tomography (CT findings are rather characteristic and pathognomonic. Thus, to consider CT as the diagnostic modality of choice is extremely important in order to diagnose the condition and to avoid unnecessary surgical interventions.             This is a paper reporting an acute abdominal pain case of primary appendicitis epiploica diagnosed using computed tomography.

    Ji Woong Lee

    2014-01-01

    Full Text Available A 27-year-old woman developed bilateral acute angle closure glaucoma (AACG and transient myopia after taking oseltamivir for four days. On the fourth day, she received systemic and topical intraocular pressure (IOP-lowering agents, and IOP decreased in both eyes. However, her visual acuity was unchanged. A myopic shift of -5.25 D OD and -5.0 D OS was estimated to have occurred in the acute phase. A-scan ultrasonography and Pentacam showed markedly shallow anterior chambers and increased lens thickness. Ultrasound biomicroscopy revealed an annular ciliochoroidal effusion with forward displacement of the lens-iris diaphragm. Ciliochoroidal effusion and transient myopia were resolved after discontinuation of oseltamivir.

Approximately 18 hours after envenomation, a 67-year-old female patient described visual impairment and severe pain in her left eye (LE. The patient’s best corrected visual acuity was 10/10 in the RE and hand motion in the LE. Cranial magnetic resonance imaging showed signs of neuropathy in the left optic nerve. In the LE, corneal haziness, closure of the iridocorneal angle, and mild mydriasis were observed and pupillary light reflex was absent. Intraocular pressure was 25 mmHg and 57 mmHg in the RE and LE, respectively. The patient was diagnosed with acute angle-closure glaucoma in the LE. Optic neuropathy was treated with intravenous pulse methylprednisolone. Left intraocular pressure was within normal range starting on the fourth day. One month after the incident, there was no sign of optic neuropathy; relative afferent pupillary defect and optic nerve swelling disappeared. Conclusions. Patients with severe headache and visual loss after snake envenomation must be carefully examined for possible optic neuropathy and angle-closure glaucoma. Early diagnosis and treatment of these cases are necessary to prevent permanent damage to optic nerves.

  16. Management of intermittent angle closure glaucoma with Nd: yag laser iridotomy as a primary procedure

    To assess the efficacy and complications of Nd: YAG laser iridotomy in patients with intermittent (sub-acute) angle closure glaucoma. Twenty-five eyes of twenty-three patients with periodic (intermittent) angle closure, selected in outpatient department, were kept on pilocarpine until YAG laser iridotomy was performed. After YAG laser iridotomy oral acetazolamide and topical dexamethasone was used to control post laser rise of IOP and inflammation respectively. Patency of iridotomy was confirmed and intra-ocular pressure was measured one hour after the procedure. Immediate complication, if any, was noted. Follow-up was done for six months. Prophylactic laser iridotomy was done in fellow eye with occludable angle. Levene's test for equality of variance and t-test for equality of means were used for statistical analysis. This study revealed a significant difference in IOP before and after YAG laser iridotomy (p = .002). Complete follow-up of 6 months was possible in 25 eyes of 23 subjects. After YAG Laser iridotomy, 21 (84%) eyes showed negative provocative test, intraocular pressure below 19mm Hg without medication and anterior chamber angle no more occludable and were labeled successful. Iridotomy remained patent in 96% of eyes. Iridotomy failed to reduce IOP in 4 (16%) eyes. The complications were minimal and transient. (author)

    Objective:To investigate the role the lens dimensions played on the pathogenesis of primary angle-closure glaucoma.Methods:38 eyes of 20 patients with primary angle-closure glaucoma (PACG) and 35 eyes of 22 normal individuals without ocular abnormalities were examined. The anatomical parameters of the lens and other structures of the anterior segment were calculated using B ultrasound, computer image processing and ultrasound biomicroscopy (UBM). The parameters were compared between the patients and normal subjects. Correlation analysis was used to determine the relationship between the radii of curvature of the anterior lens surface (RCALS) and the other parameters of the anterior segment. Results:Compared with the normal eyes, the eyes of PACG had thicker lens, steeper curvature of anterior lens surface, decreased depth of the anterior chamber, narrower chamber angle, and more anterior position of the ciliary bodies and lens. All these differences were significant(P < 0.05 or P < 0.01). In the PACG group, the RCALS had significantly negative correlation with the central and peripheral lens thickness (P < 0.01 and P < 0.05 respectively), and had positive correlation with relative lens position, anterior chamber depth (ACD), angle-open distance at 500 um(AOD500), trabecular iris angle(TIA) and trabecular ciliary processes distance(TCPD, P < 0.05 or P < 0.01 ). Conclusion:The occurrence of PACG is relevant to the abnormal anatomical structures of the anterior segment. Among all factors, the lens parameters play an important role in the pathogenesis. Increased lens thickness, relative more anterior position of lens, especially steepened curvature of anterior lens surface are predisposing factors of the pathologic phenomenon in PACG including pupillary blockage, shallow anterior chamber, secondary closure of chamber angle and elevation of intraocular pressure.

    Vodovozov, A M; Rybnikov, A A

    1991-01-01

    The iris was examined in transformed light by iridochromoscopy, iridochromophotography, biomicroscopy in polarized light, transillumination in red light, and fluorescent iridoangiography in 83 eyes of patients with primary open-angle glaucoma and 117 eyes of normal reference subjects. The examinations have shown the prevalence of trophic and vascular shifts in the iris of all glaucoma patients as against the reference patients (R 0.05). The major iris changes revealed in primary open-angle glaucoma were stromal atrophy with the predominant involvement of the pupil segment, destruction of the pupil pigmented border, exogenic pigmentation of the pupil and ciliary segments, thickening of the anterior border layer, pseudoexfoliation of the pupil edge, defects of the posterior pigmented lamina disseminated in the pupil segment, hypoperfusion of the iris vessels combined with their impaired permeability and micro-neovascularization in the iris edge and ciliary agea.

  19. Ultrasonic Evaluation of the Lens Thickness to Axial Length Factor in Primary Closure Angle Glaucoma

    1993-01-01

    Ultrasonic biometry was done in 232 normal eyes and 138 eyes with primary angle closure glaucoma (ACG), using Ultrascan Digital B System IV (10 MHz). The ratio between the lens thickness and the axial length (lens thickness to axial length factor, LAF) was evaluated as a biometric index for assessing the eye with primary ACG in Chinese. LAF of 2.00 was found to be ideal point of demarcation between ACG and normal eyes (i.e., lens thickness equals to 1/5 of axial length). It appears that LAF is helpful i...

    2013-02-01

    Full Text Available This paper describes a topiramate induced acute bilateral angle-closure glaucoma. This rare adverse effect is an idiosyncratic reaction characterized by uveal effusion and lens forward displacement, leading to increased intraocular pressure and vision loss. We describe a 55 year-old white woman with migraine, spasmodic torticollis and essential tremor, who developed bilateral acute angle-closure glaucoma, one week after starting topiramate 25 mg/day. She was seen at the Ophthalmology Emergency Department of the Fundação João Penido Burnier (Campinas, SP, Brazil with a 4 hours history of blurry vision, ocular pain and bright flashes vision. Slit lamp examination revealed moderate conjunctival injection and corneal edema, and shallow anterior chambers. Intraocular pressure was 48 mmHg in both eyes. Fundoscopic examination findings were normal. She was treated with timolol, brimonidine, dorzolamide, pilocarpine, prednisone acetate eye drops and acetazolamide. One hour after those measures, as the intraocular pressure was 30 mmHg, she received a manitol intravenous injection and the intraocular pressure normalized. After 24 hours an iridotomy with Yag laser was performed. Topiramate was discontinued and she was totally recovered after one week.

    Elevated degree of body fatness and changes in other body composition parameters are known to be common effects of treatment for acute lymphoblastic leukemia (ALL) in children. In order to study peculiarities of somatic growth and development in ALL survivors, we describe the results of BIA body composition analysis of 112 boys and 108 girls aged 5-18 years in remission from ALL (remission time range 1-13 years) compared to data from the same number of age- and sex-matched healthy controls (n=220). Detrimental effect on height in ALL boys was observed, whereas girls experienced additional weight gain compared to healthy subjects. In ALL patients, resistance, body fat, and percent body fat were significantly increased. The reactance, phase angle, absolute and relative values of skeletal muscle and body cell mass were significantly decreased. Principal component analysis revealed an early prevalence of adiposity traits in the somatic growth and development of ALL girls compared to healthy controls.

    2013-05-01

    Full Text Available Aims: To test for anti-endothelial and anti-neurotrophic effects from autoantibodies in subsets of diabetes having open- angle glaucoma, dementia or control subjects.Methods: Protein-A eluates from plasma of 20 diabetic subjects having glaucoma or suspects and 34 age-matched controls were tested for effects on neurite outgrowth in rat pheochromocytoma PC12 cells or endothelial cell survival. The mechanism of the diabetic glaucoma autoantibodies' neurite inhibitory effect was investigated in coincubations with the selective Rho kinase inhibitor Y27632 or the sulfated proteoglycan synthesis inhibitor sodium chlorate. Stored protein-A eluates from certain diabetic glaucoma or dementia subjects which contained long-lasting, highly stable cell inhibitory substances were characterized using mass spectrometry and amino acid sequencing.Results: Diabetic primary open angle glaucoma or suspects (n=20 or diabetic dementia (n=3 autoantibodies caused significantly greater mean inhibition of neurite outgrowth in PC12 cells (p < .0001 compared to autoantibodies in control diabetic (n=24 or nondiabetic (n=10 subjects without glaucoma (p < .01. Neurite inhibition by the diabetic glaucoma autoantibodies was completely abolished by 10 µM concentrations of Y27632 (n=4. It was substantially reduced by 30 mM concentrations of sodium chlorate (n=4. Peak, long-lasting activity survived storage x 5 years at 0-4 deg C and was associated with a restricted subtype of Ig kappa light chain. Diabetic glaucoma or dementia autoantibodies (n=5 caused contraction and process retraction in quiescent cerebral cortical astrocytes effects which were blocked by 5 µM concentrations of Y27632. Conclusion: These data suggest that autoantibodies in adult diabetes having primary open angle glaucoma (glaucoma suspects and/or dementia inhibit neurite outgrowth and promote a reactive astrocyte morphology by a mechanism which may involve activation of the RhoA/p160 ROCK signaling pathway.

  15. Focused-ion-beam-fabricated homogeneous acute-angled Au nanorods for surface-enhanced Raman scattering

    Well-ordered acute-angled Au nanorod (NR) arrays were fabricated using a focused ion beam (FIB) (fibAu-NR). The angle between the NRs and the substrate was tilted at 30-90deg. A fibAu-NR with an angle of less than 90deg significantly increased the effect of surface-enhanced Raman scattering, which was evaluated using low-concentration rose bengal (<10-5 M) as the molecular test probe. The results show that an angled NR surface produces a strong local electromagnetic effect owing to a large number of Raman active sites. In addition, an optimized fibAu-NR was found to distinguish cyanuric acid in milk solution with good reproducibility. (author)

    Bilkis, Valdas; Kibarskis, Aleksandras; Abraitis, Vytautas

    2004-01-01

    Randomized controlled trials that compared primary percutaneous transluminal coronary angioplasty with thrombolysis have shown that primary angioplasty is more effective than intravenous thrombolysis in reducing mortality and morbidity in patients with acute myocardial infarction. Three large myocardial infarction registries - MITI, NRMI-2 and French registry - failed to show an advantage of primary angioplasty compared with thrombolysis. One of the latest trials mentioned in this paper restored the place of primary angioplasty as superior to thrombolysis in acute myocardial infarction. Data of patients treated with primary percutaneous transluminal coronary angioplasty in Clinic of Cardiology of Vilnius University are presented. PMID:15079110

    2015-09-01

    The topic of acute dyspnea is presented in two separate articles. This first part deals with the definition and pathophysiology of dyspnea as well as important considerations on the history of the present illness, physical examination, initial therapy and differential diagnostic considerations. The second part covers relevant diagnostic investigations and principles for the initial management. The causes, consequences and perception of acute dyspnea can be very different. The adult patient with acute dyspnea presents difficult challenges in the diagnosis and management. The emergency clinician must work through a wide range of differential diagnostic considerations while providing appropriate initial treatment for a potentially life-threatening disease.

The progression of visual field defects was defined by a significantly negative value of the mean deviation slope at the final visual field test during the follow-up period. The relationships between the progression of visual field defects and IOP, as well as other clinical factors, were retrospectively analyzed.Results: A total of 156 eyes of 156 patients were included in the analysis. Significant progression of visual field defects was observed in 70 eyes of 70 patients (44.9%, while no significant progression was evident in 86 eyes of 86 patients (55.1%. The eyes with visual field defect progression had significantly lower baseline IOP (P<0.05, as well as significantly lower IOP reduction rate (P<0.01. The standard deviation of IOP values during follow-up was significantly greater in the eyes with visual field defect progression than in eyes without (P<0.05.Conclusion: Reducing IOP is thought to be useful for Japanese POAG or NTG patients to suppress the progression of visual field defects. In NTG, IOP management should take into account not only achieving the target IOP, but also

    Full Text Available Intraocular pressure (IOP is a highly heritable risk factor for primary open-angle glaucoma and is the only target for current glaucoma therapy. The genetic factors which determine IOP are largely unknown. We performed a genome-wide association study for IOP in 11,972 participants from 4 independent population-based studies in The Netherlands. We replicated our findings in 7,482 participants from 4 additional cohorts from the UK, Australia, Canada, and the Wellcome Trust Case-Control Consortium 2/Blue Mountains Eye Study. IOP was significantly associated with rs11656696, located in GAS7 at 17p13.1 (p=1.4×10(-8, and with rs7555523, located in TMCO1 at 1q24.1 (p=1.6×10(-8. In a meta-analysis of 4 case-control studies (total N = 1,432 glaucoma cases, both variants also showed evidence for association with glaucoma (p=2.4×10(-2 for rs11656696 and p=9.1×10(-4 for rs7555523. GAS7 and TMCO1 are highly expressed in the ciliary body and trabecular meshwork as well as in the lamina cribrosa, optic nerve, and retina. Both genes functionally interact with known glaucoma disease genes. These data suggest that we have identified two clinically relevant genes involved in IOP regulation.

  4. Anterior chamber depth and primary angle-closure glaucoma. II. A genetic study.

    1975-06-01

    The genetics of primary angle-closure glaucome (a.c.g.) was studied: a) through the prevalence in sibs and children of a.c.g. probands, and b) through the family distribution of the closely correlated axial anterior chamber depth (ACD). The material emerged from an epidemiologic study in Greeland Eskimos. a) Compared with the general population, the observed prevalence of a.c.g. was increased in sibs of a.c.g. probands and the estimated, future prevalence was found to be the same in sibs and children. Age influence prevented a proper Mendelian analysis, but no simple monogenic inheritance seems probable. b) The biometric study showed a relatively shallow chamber in sibs, children, nephews, nieces and grandchildren of a.c.g. probands. Regression analyses revealed a corresponding pattern, also in control families of probands with shallow chambers and in general population families. A heritability of 70% was found, indicating that about two thirds of the age and sex independent variation in ACD seems to be genetic. PMID:1174403

    Full Text Available Electronic medical records (EMRs are being widely implemented for use in genetic and genomic studies. As a phenotypic rich resource, EMRs provide researchers with the opportunity to identify disease cohorts and perform genotype-phenotype association studies. The Epidemiologic Architecture for Genes Linked to Environment (EAGLE study, as part of the Population Architecture using Genomics and Epidemiology (PAGE I study, has genotyped more than 15,000 individuals of diverse genetic ancestry in BioVU, the Vanderbilt University Medical Center's biorepository linked to a de-identified version of the EMR (EAGLE BioVU. Here we develop and deploy an algorithm utilizing data mining techniques to identify primary open-angle glaucoma (POAG in African Americans from EAGLE BioVU for genetic association studies. The algorithm described here was designed using a combination of diagnostic codes, current procedural terminology billing codes, and free text searches to identify POAG status in situations where gold-standard digital photography cannot be accessed. The case algorithm identified 267 potential POAG subjects but underperformed after manual review with a positive predictive value of 51.6% and an accuracy of 76.3%. The control algorithm identified controls with a negative predictive value of 98.3%. Although the case algorithm requires more downstream manual review for use in large-scale studies, it provides a basis by which to extract a specific clinical subtype of glaucoma from EMRs in the absence of digital photographs.

    Full Text Available Objective: To study drug use pattern in patients of primary open angle glaucoma (POAG and to analyze the cost of different anti-glaucoma medications. Materials and Methods: This prospective study was carried in the glaucoma clinic of a tertiary care teaching hospital over a period of 9 months. The data collected for patients with POAG included the patient′s demographic details and the drugs prescribed. Data were analyzed for drug use pattern and cost drugs used. Results: In a total 180 prescriptions (297 drugs analyzed, most drugs (83.83% were prescribed by topical route as eye drops. β blockers (93.88% were found to be the most frequently prescribed for POAG. Timolol (82.22% was the most frequently prescribed drug and timolol with acetazolamide (17.22% was the most commonly prescribed drug combination. Fixed dose combinations constituted 26.66% of prescriptions. β blockers were found to be cheaper than other anti-glaucoma drugs while prostaglandins analogs were the costliest. Instructions about the route, frequency and duration of treatment were present in all prescriptions. However, instructions regarding instillation of eye drops were missing in all prescriptions.

    Primary open-angle glaucoma (POAG) and age-related macular degeneration (AMD) are leading causes of irreversible blindness. Several loci have been mapped using genome-wide association studies. Until very recently, there was no recognized overlap in the genetic contribution to AMD and POAG. At genome-wide significance level, only ABCA1 harbors associations to both diseases. Here, we investigated the genetic architecture of POAG and AMD using genome-wide array data. We estimated the heritability for POAG (h2g = 0.42 ± 0.09) and AMD (h2g = 0.71 ± 0.08). Removing known loci for POAG and AMD decreased the h2g estimates to 0.36 and 0.24, respectively. There was evidence for a positive genetic correlation between POAG and AMD (rg = 0.47 ± 0.25) which remained after removing known loci (rg = 0.64 ± 0.31). We also found that the genetic correlation between sexes for POAG was likely to be less than 1 (rg = 0.33 ± 0.24), suggesting that differences of prevalence among genders may be partly due to heritable factors.

    Primary angle closure glaucoma (PACG) is a major cause of blindness worldwide. We conducted a genome-wide association study (GWAS) followed by replication in a combined total of 10,503 PACG cases and 29,567 controls drawn from 24 countries across Asia, Australia, Europe, North America, and South America. We observed significant evidence of disease association at five new genetic loci upon meta-analysis of all patient collections. These loci are at EPDR1 rs3816415 (odds ratio (OR) = 1.24, P = 5.94 × 10(-15)), CHAT rs1258267 (OR = 1.22, P = 2.85 × 10(-16)), GLIS3 rs736893 (OR = 1.18, P = 1.43 × 10(-14)), FERMT2 rs7494379 (OR = 1.14, P = 3.43 × 10(-11)), and DPM2-FAM102A rs3739821 (OR = 1.15, P = 8.32 × 10(-12)). We also confirmed significant association at three previously described loci (P < 5 × 10(-8) for each sentinel SNP at PLEKHA7, COL11A1, and PCMTD1-ST18), providing new insights into the biology of PACG.

    Purpose To estimate the population frequencies of all common mitochondrial variants and ancestral haplogroups among 1,999 subjects recruited for the Primary Open-Angle African American Glaucoma Genetics (POAAGG) Study, including 1,217 primary open-angle glaucoma (POAG) cases and 782 controls, and to identify ancestral subpopulations and mitochondrial mutations as potential risk factors for POAG susceptibility. Methods Subject classification by characteristic glaucomatous optic nerve findings and corresponding visual field defects, as defined by enrolling glaucoma specialists, stereo disc photography, phlebotomy, extraction of total DNA from peripheral blood or saliva, DNA quantification and normalization, PCR amplification of whole mitochondrial genomes, Ion Torrent deep semiconductor DNA sequencing on DNA pools (“Pool-seq”), Sanger sequencing of 3,479 individual mitochondrial DNAs, and bioinformatic analysis. Results The distribution of common African haplogroups within the POAAGG study population was broadly similar to prior surveys of African Americans. However, the POAG case population was found to be enriched in L1c2 haplogroups, which are defined in part by missense mutations m.6150G>A (Val83Ile, odds ratio [OR] 1.8, p=0.01), m.6253C>T (Met117Thr, rs200165736, OR 1.6, p=0.04), and m.6480G>A (Val193Ile, rs199476128, OR 4.6, p=0.04) in the cytochrome c oxidase subunit 1 (MT-CO1) gene and by a variant, m.2220A>G (OR 2.0, p=0.01), in MT-RNR2, which encodes the mitochondrial ribosomal 16s RNA gene. L2 haplogroups were predicted to be overrepresented in the POAG case population by Pool-seq, and the difference was confirmed to be significant with Sanger sequencing, that targeted the L2-associated variants m.2416T>C (rs28358580, OR 1.2, p=0.02) and m.2332C>T (OR 1.2, p=.02) in MT-RNR2. Another variant within MT-RNR2, m.3010G>A (rs3928306), previously implicated in sensitivity to the optic neuropathy-associated antibiotic linezolid, and arising on D4 and J1

    Full Text Available Background: Obstructive sleep apnea (OSA is partial or complete recurrent upper airway obstructions during sleep. Reduction in blood flow of the optic nerve head is an important causative factor in glaucoma. The objective of this study is to determine the prevalence of primary open angle glaucoma (POAG in OSA patients. Materials and Methods: From September 2009 to January 2010 in this descriptive-analytic cross sectional study, 90 cases of patients with OSA referred to Yazd Shahid Sadoughi hospital were collected and studied by polysomnography, blood gas analysis and ocular examination including measurement of intra ocular pressure, gonioscopy, fondoscopy and automated perimetry. Statistical analysis was performed by SPSS software6T. Results: Thirty-one patients had mild OSA, 30 patients had moderate OSA and 29 patients had severe OSA. The prevalence of POAG in this group of patients was 10% (95% CI: 4-16. It is higher than the general population in the same age group (p=0.017. There was no significant correlation between the presence of glaucoma and apnea hypopnea index (AHI, mean saturation arterial OR2R (MSaOR2R, body mass index (BMI, sex and age. A significant correlation between AHI with IOP and cup/disc ratio was not documented6T. Conclusion: According to our founding, the prevalence of POAG in OSA patients was higher than the general population in the same age group. Thus we recommend screening of glaucoma in OSA patients. This Study suggests that AHI, MSaOR2R, BMI, sex or age are not important risk factors for glaucoma in OSA patients6T

  13. Axial Myopia Is Associated with Visual Field Prognosis of Primary Open-Angle Glaucoma.

    Chen Qiu

    Full Text Available To identify whether myopia was associated with the visual field (VF progression of primary open-angle glaucoma (POAG.A total of 270 eyes of 270 POAG followed up for more than 3 years with ≥9 reliable VFs by Octopus perimetry were retrospectively reviewed. Myopia was divided into: mild myopia (-2.99 diopter [D], 0, moderate myopia (-5.99, 3.00 D, marked myopia (-9.00, -6.00 D and non-myopia (0 D or more. An annual change in the mean defect (MD slope >0.22 dB/y and 0.30 dB/y was defined as fast progression, respectively. Logistic regression was performed to determine prognostic factors for VF progression.For the cutoff threshold at 0.22 dB/y, logistic regression showed that vertical cup-to-disk ratio (VCDR; p = 0.004 and the extent of myopia (p = 0.002 were statistically significant. When logistic regression was repeated after excluding the extent of myopia, axial length (AL; p = 0.008, odds ratio [OR] = 0.796 reached significance, as did VCDR (p = 0.001. Compared to eyes with AL≤23 mm, the OR values were 0.334 (p = 0.059, 0.309 (p = 0.044, 0.266 (p = 0.019, 0.260 (p = 0.018, respectively, for 23 26 mm. The significance of vertical cup-to-disk ratio of (p = 0.004 and the extent of myopia (p = 0.008 did not change for the cutoff threshold at 0.30dB/y.VCDR and myopia were associated with VF prognosis of POAG. Axial myopia may be a protective factor against VF progression.

    2016-01-01

    Purpose. To describe a modified guarded filtration surgery, stab incision glaucoma surgery (SIGS), for primary open angle glaucoma (POAG). Methods. This prospective, interventional case series included patients with POAG (IOP ≥21 mmHg with glaucomatous visual field defects). After sliding superior conjunctiva down over limbus, 2.8 mm bevel-up keratome was used to create conjunctival entry and superficial corneoscleral tunnel in a single step starting 1.5 mm behind limbus. Lamellar corneoscleral tunnel was carefully dissected 0.5–1 mm into cornea and anterior chamber (AC) was entered. Kelly Descemet's punch (1 mm) was slid along the tunnel into AC to punch internal lip of the tunnel, thereby compromising it. Patency of ostium was assessed by injecting fluid in AC and visualizing leakage from tunnel. Conjunctival incision alone was sutured. Results. Mean preoperative IOP was 27.41 ± 5.54 mmHg and mean postoperative IOP was 16.47 ± 4.81 mmHg (n = 17). Mean reduction in IOP was 38.81 ± 16.55%. There was significant reduction of IOP (p < 0.000). 64.7% had IOP at final follow-up of <18 mmHg without medication and 82.35% had IOP <18 mmHg with ≤2 medications. No sight threatening complications were encountered. Conclusion. Satisfactory IOP control was noted after SIGS in interim follow-up (14.18 ± 1.88 months). PMID:27144015

    2013-01-01

    Full Text Available Purpose: To evaluate the safety and efficacy of viscocanalostomy in the management of medically uncontrollable primary open-angle glaucoma (POAG in a developing country. Materials and Methods: This is a prospective, non-randomized case series of 14 consecutive eyes with medically uncontrollable POAG, all subjected to viscocanalostomy. The main outcome measure was success rate based on the intraocular pressure (IOP level achieved post-operatively. The procedure was considered a complete success if IOP was less than 21 mmHg without any anti-glaucoma medication. Qualified success was defined as IOP of less than 21 mmHg with anti-glaucoma medication. All patients had a regular follow-up of at least 12 months. Results: IOP was reduced from a mean baseline value of 27.9 ± 7.3 mmHg (range: 21-40 mmHg to a mean final value of 16.0 ± 2.7 mmHg (range: 13-22 mmHg, which was statistically highly significant (P < 0.005. The mean number of pre-operative anti-glaucoma medications was 3.0 ± 0.4 (range: 2-4, which was reduced significantly (P < 0.0001 to 0.3 ± 0.6 (range: 0-2 at the last follow-up visit. One year post-operatively, complete success was achieved in 71% and qualified success was observed in 21.4% of patients, summing up to an overall success rate of 92.4%. There were no major complications in any of the patients. Conclusion: Viscocanalostomy could be performed effectively and safely for control of POAG in developing countries.

  16. Discovery and functional annotation of SIX6 variants in primary open-angle glaucoma.

    Megan Ulmer Carnes

    Full Text Available Glaucoma is a leading cause of blindness worldwide. Primary open-angle glaucoma (POAG is the most common subtype and is a complex trait with multigenic inheritance. Genome-wide association studies have previously identified a significant association between POAG and the SIX6 locus (rs10483727, odds ratio (OR = 1.32, p = 3.87×10(-11. SIX6 plays a role in ocular development and has been associated with the morphology of the optic nerve. We sequenced the SIX6 coding and regulatory regions in 262 POAG cases and 256 controls and identified six nonsynonymous coding variants, including five rare and one common variant, Asn141His (rs33912345, which was associated significantly with POAG (OR = 1.27, p = 4.2×10(-10 in the NEIGHBOR/GLAUGEN datasets. These variants were tested in an in vivo Danio rerio (zebrafish complementation assay to evaluate ocular metrics such as eye size and optic nerve structure. Five variants, found primarily in POAG cases, were hypomorphic or null, while the sixth variant, found only in controls, was benign. One variant in the SIX6 enhancer increased expression of SIX6 and disrupted its regulation. Finally, to our knowledge for the first time, we have identified a clinical feature in POAG patients that appears to be dependent upon SIX6 genotype: patients who are homozygous for the SIX6 risk allele (His141 have a statistically thinner retinal nerve fiber layer than patients homozygous for the SIX6 non-risk allele (Asn141. Our results, in combination with previous SIX6 work, lead us to hypothesize that SIX6 risk variants disrupt the development of the neural retina, leading to a reduced number of retinal ganglion cells, thereby increasing the risk of glaucoma-associated vision loss.

    Background Trabeculectomy has become a mainstream treatment in intraocular pressure (IOP) reduction for primary angle-closure glaucoma (PACG); combined trabeculectomy and cataract surgery was reported to reduce lOP and simultaneously improve vision for patients with PACG and coexisting cataract.This study was specialized to compare the efficacy and safety of combined phacotrabeculectomy with that of trabeculectomy only in the treatment of PACG with coexisting cataract.Methods This is a comparative case series study.Thirty-one patients (31 eyes) with PACG and coexisting cataract were enrolled.Of these,17 underwent phacotrabeculectomy and 14 underwent trabeculectomy alone.lOP,filtering blebs,and complications were compared at the final follow-up.Complete success was defined as a final lOP less than 21 mmHg without lOP-lowering medication.Results After 10 months of postoperative follow-up,the phacotrabeculectomy and trabeculectomy groups showed no significant differences regarding IOP reduction ((20.59±7.94) vs.(24.85±14.39) mmHg,P=0.614),complete success rate (88% vs.71%,P=0.370),formation rate of functioning blebs (65% (11/17) vs.93% (13/14),P=0.094),and complications (41% (7/17) vs.57% (8/14),P=0.380).lOP-lowering medication was not required for most of the patients in both groups.Additional surgery interventions,including anterior chamber reformation and phacoemulsification,were needed in the trabeculectomy group,whereas no surgery was needed postoperatively in the phacotrabeculectomy group.Conclusion Phacotrabeculectomy and trabeculectomy treatments exhibit similar IOP reduction,successful rates,and complications when it comes to treating PACG patients with coexisting cataract,although additional surgery intervention may be needed for a few cases with cataract and complications after trabeculectomy.

    Tsoukos, A, Bogdanis, GC, Terzis, G, and Veligekas, P. Acute improvement of vertical jump performance after isometric squats depends on knee angle and vertical jumping ability. J Strength Cond Res 30(8): 2250-2257, 2016-This study examined the acute effects of maximum isometric squats at 2 different knee angles (90 or 140°) on countermovement jump (CMJ) performance in power athletes. Fourteen national-level male track and field power athletes completed 3 main trials (2 experimental and 1 control) in a randomized and counterbalanced order 1 week apart. Countermovement jump performance was evaluated using a force-plate before and 15 seconds, 3, 6, 9, and 12 minutes after 3 sets of 3 seconds maximum isometric contractions with 1-minute rest in between, from a squat position with knee angle set at 90 or 140°. Countermovement jump performance was improved compared with baseline only in the 140° condition by 3.8 ± 1.2% on the 12th minute of recovery (p = 0.027), whereas there was no change in CMJ height in the 90° condition. In the control condition, there was a decrease in CMJ performance over time, reaching -3.6 ± 1.2% (p = 0.049) after 12 minutes of recovery. To determine the possible effects of baseline jump performance on subsequent CMJ performance, subjects were divided into 2 groups ("high jumpers" and "low jumpers"). The baseline CMJ values of "high jumpers" and "low jumpers" differed significantly (CMJ: 45.1 ± 2.2 vs. 37.1 ± 3.9 cm, respectively, p = 0.001). Countermovement jump was increased only in the "high jumpers" group by 5.4 ± 1.4% (p = 0.001) and 7.4 ± 1.2% (p = 0.001) at the knee angles of 90 and 140°, respectively. This improvement was larger at the 140° angle (p = 0.049). Knee angle during isometric squats and vertical jumping ability are important determinants of the acute CMJ performance increase observed after a conditioning activity. PMID:26808841

  20. MR diffusion tensor imaging of optic nerve in patients with primary chronic angle-closure glaucoma

    Objective: To investigate the value of MR diffusion tensor imaging (DTI) of optic nerve in the estimation of optic nerve changes of primary chronic angle-closure glaucoma (PCACG). Methods: Twenty-five patients with PCACG including monocular involvement in 4 patients and binocular involvement in 21 patients and involving 46 eyes in which 24 right eyes and 22 1eft eyes, and 20 normal volunteers were enrolled.Conventional MRI and DTI were performed on all subjects using Magnetom Tim 3.0 T MRI. Fractional anisotropy(FA), mean diffusivity (MD), axial diffusivities (λ ∥) and radial diffusivities (λ ⊥) were measured and then compared between patients group and control group and between left eyes and right eyes. Two independent samples t-test and paired t-test were used. Results: On conventional MRI, thinner optic nerve with vaginal cavity widened slightly was found in 8 optic nerves of 6 patients.The value of FA, λ∥, λ⊥ and MD of 24 right optic nerves in patient group was(0.27 ± 0.09) × 10-3, (2.30 ±0.26) × 10-3, (1.55 ± 0.35) × 10-3, and (1.80 ± 0.31) × 10-3 mm2/s respectively and that of 22 left optic nerves was (0.24 ± 0.09) × 10-3,(2.25 ± 0.41) × 10-3,(1.61 ± 0.46) × 10-3, and (1.82 ±0.47) × 10-3 mm2/s respectively. The FA of optic nerve in patient group was lower than that of control group (P<0.05), while the mean λ∥, λ ⊥ and MD values was obviously higher than control group (P<0.05). There was no significant difference between right and left optic nerves in patient group (P>0.05). Conclusions: DTI could detect abnormality and provide information about the pathological process of optic nerve in patients with PCACG. (authors)

    2009-11-01

    Full Text Available Abstract Background The transmembrane glycoprotein CD44 is a major hyaluronan cell surface receptor widely distributed in eye tissues and fluids. The shed ectodomain of CD44 is termed soluble CD44 and is toxic to human retinal ganglion cells in cell culture. The purpose of this study was to investigate the concentration of sCD44 in the aqueous humor (AH of normal subjects, patients with primary open-angle glaucoma, and patients with degenerative myopia but without glaucoma, to determine if the molecule might serve as a protein marker of glaucoma. Findings In this case-control study, AH samples were collected from controls (n = 16, patients with primary open-angle glaucoma (n = 11, and patients with degenerative myopia (n = 11 who underwent phacoemulsification surgery to treat mature or immature cataracts. The sCD44 concentration in AH was measured using a commercial ELISA kit. In normal AH samples the sCD44 concentration was 5.40 ± 1.21 ng/mL, whereas in degenerative myopia patients the sCD44 concentration was 5.76 ± 1.15 ng/mL. There was thus no statistically significant difference between these two groups (p > 0.05. The aqueous sCD44 concentration in patients with primary open-angle glaucoma (12.2 ± 10.1 ng/mL was higher than that of the control group (p Conclusion sCD44 may be a protein marker of primary open-angle glaucoma.

    1990-08-01

    The case is reported of a 39-year-old pregnant woman who presented with fever, abdominal complaints, and diarrhea. Laboratory investigation revealed mononucleosis in the peripheral blood. All microbiological studies were negative, with the exception of finding cytomegalovirus (CMV). Seroconversion was documented; the virus was cultured from urine and subsequently was demonstrated to be present in the inflamed mucosa of the rectum and distal sigmoid, which was found at sigmoidoscopy. This woman was delivered of a neonate with congenital CMV infection but without apparent malformations. The patient experienced recurrences of the bowel disease, in the first of which CMV could still be cultured from a biopsy specimen. In the follow-up period, an otherwise aspecific chronic inflammatory bowel disease remained present. No immunological abnormalities were found, and antibodies to human immunodeficiency virus were negative. This case demonstrates that inflammatory bowel disease can develop as a result of primary infection with CMV. PMID:2166491

    Objective To investigate the mechanisms of angle closure through observing changes of anterior segment morphology after laser peripheral iridotomy (LPI) in eyes with primary angle closure (PAC).Methods A prospective intervention observational case series.Forty-eight eyes with PAC,which were examined by ultrasound biomicroscopy (UBM) in darkness,were divided into three groups:The group A,simple pupillary block group; the group B,multi-mechanism group,the group C (0),simple pure non-pupillary block group.Ultrasound biomicroscopy examination was carried out before and 2 weeks after LPI treatment was preformed on PAC.UBM parameters included AOD,TIA,IT1,TCPD,ILA,ILCD,SS-IR.Results 1.Composition of the PAC was:simple pupillary block group (9 eyes,18.75%); multiple mechanism group (39 eyes,81.25%); simple pure non-pupillary block group (0 eye,0%).In multiple mechanism group (39 eyes,81.25%),there were 14.6% (7 eyes) in pupillary blocking coexisting a anterior positioned ciliary body; 12.5% (6 eyes) in pupillary blocking coexisting a thicker iris; 54.2% (26 eyes) in pupillary blocking coexisting a thicker iris and a anterior positioned ciliary body.2.The rate of angle open after LPI was 100% (9/9) in simple pupillary block group,and 41.0% (16/39) in multiple mechanism group (P =0.001).3.The preoperative peripheral iris thickness of group B (0.4029±0.0466mm) was thicker than that of group A (0.3248±0.0520mm) (P <0.05).Angle opening degree after LPI in group A were significantly increased (AOD500,TIA) compared with group B (P <0.05).There were no significant differences in iris bombe degree (ILCD,ILA) between group A and group B after LPI (P >0.05).After LPI,SS-IR in angle closure points were significantly shorter than in angle opening points (P <0.05).Conclusions The mechanism of primary angle closure is main multiple mechanism.Both a thicker iris and an anterior positioned ciliary body played a key role in the pathogenesis of angle closure after

  12. A rare case of primary EBV infection causing acute acalculous cholecystitis

    Sonia Shah

    2015-07-01

    Full Text Available Primary Epstein–Barr Virus (EBV infection in children is common and frequently asymptomatic. While symptomatic patients typically present with features of infectious mononucleosis, a rare complication of primary EBV is acute acalculous cholecystitis. A 6 year old previously healthy boy presented with 6 days of low-grade fevers, non-bloody non-bilious vomiting, and periumbilical pain. Based on clinical, laboratory, and radiographic evidence, the patient was diagnosed with acute acalculous cholecystitis due to a primary EBV infection. The patient improved with supportive therapy and remained asymptomatic at follow-up. Overall, clinicians should consider EBV infection in the setting of multi-organ disease and blood dyscrasia. Furthermore, while the pathogenesis of EBV cholecystitis is still unclear, it is important to note that these patients may improve with supportive treatment and do not require surgical intervention.

    2015-01-01

    Metastatic adenocarcinoma in bilateral cerebellopontine angles (CPA) is rare. We report a case and review the current literature in order to enhance recognition of metastatic adenocarcinoma in the cerebellopontine angle. A 44-year-old man was referred to the hospital with rightsided diminished hearing for 7 weeks, left-sided facial palsy for 2 weeks, and left-sided sensorineural hearing loss for 1 week. On Magnetic Resonance Imaging (MRI) two tumors in bilateral CPAs were detected. The left-sided tumor was resected and histopathological examination revealed an adenocarcinoma. Many investigations could not find the primary tumor. One should be careful with middle-aged or elderly patients with sudden progressive deficits in the VIII th or VII th cranial nerves, particularly in bilateral CPA. PMID:26617145

    Objective To evaluate the association between baseline measurements of iris thickness at three positions and change in anterior segment biometric parameters after prophylactic laser peripheral iridotomy (LPI). Design Prospective clinical cohort study. Participants Fifty-two eyes of 52 nonglaucomatous subjects with anatomically narrow angles. Methods Anterior segment optical coherence tomography images captured before and after LPI were analyzed using customized software, the Zhongshan Angle Assessment Program. Differences in preoperative and postoperative measurements for anterior segment biometric parameters were compared by paired Student’s t-tests. Multivariate linear regression models, adjusted for age, sex, ethnicity, and preoperative pupil diameter, were used to examine the association between the baseline measurements of iris thickness at three positions and the change in anterior segment biometric parameters after LPI. Main Outcome Measures Baseline iris thickness measured at 750μm (IT750) and 2000μm (IT2000) from the scleral spur and maximal iris thickness (ITM). Changes in iris curvature (ICURV) and trabecular–iris space area at 500μm (TISA500) and 750μm (TISA750) from the scleral spur after LPI. Results ICURV significantly decreased, while TISA500 and TISA750 significantly increased following LPI (all PTISA500 and TISA750 (both PTISA500 and TISA750 after LPI. This suggests that eyes with thinner irides undergoing LPI were more likely to exhibit greater magnitude of change in terms of flattening of the iris convexity (i.e., ICURV) and widening of the anterior chamber angle (i.e., TISA500 and TISA750).

This study was designed to determine the effect of primary percutaneous coronary intervention (PCI in patients with CAVB complicating acute inferior STEMI, at a single center.Methods: We enrolled 138 consecutive patients diagnosed with STEMI involving the inferior wall; of these, 27 patients had CAVB. All patients received primary PCI. The clinical characteristics, procedural data, and clinical outcomes were compared in patients with versus without CAVB. Results: Baseline clinical characteristics were similar between patients with and without CAVB. Patients with CAVB were more likely to present with cardiogenic shock, and CAVB was caused primarily by right coronary artery occlusion. Door-to-balloon time was similar between those two groups. After primary PCI, CAVB was reversed in all patients. The peak creatinine phosphokinase level, left ventricular ejection fraction and in-hospital mortality rate were similar between the two groups. After a median follow up of 318 days, major adverse cardiac events did not differ between the groups (8.1% in patients without CAVB; 11.1% in patients with CAVB (P=0.702.Conclusion: We conclude that primary PCI can ameliorate CAVB-complicated acute inferior STEMI, with an acceptable rate of major adverse cardiac events, and suggest that primary PCI should be the preferred reperfusion therapy in patients with CAVB complicating acute inferior myocardial infarction. Keywords: major adverse cardiac events, PCI-capable hospital

  20. [Surgery in the treatment of primary advanced open-angle glaucoma].

    Chiseliţă, D; Vancea, P P

    1995-01-01

    A series of 25 cases of advanced open-angle primitive glaucoma (C/D higher than 0.8, visual field stages C, D, E according to Greve's classification), operated upon by extended and adapted trabeculectomy, surgery being the initial step in the treatment of this affection, was reviewed. After a 18.5-month follow up, the progression of glaucoma was arrested in 60% of the cases, and a regression of papilloperimetric alterations was found in 8% of the cases. There was a significant correlation between the obtained IOP level and glaucoma course (in the cases with a favourable course postoperative IOP was of 15.5 mmHg, while in those evolving unfavorably IOP was of 18 mmHg). Our experience suggests that antiglaucoma surgery may be recommended as an initial treatment in those patients in whom a short-term drug trial (topic administration of 3 drugs for few days) induces a lowering of IOP to less than 15.5 mmHg, and life expectancy is not short.

    Full Text Available The objective of this study is to compare the reduction of intraocular pressure (IOP after instillation of Travoprost compared with timolol in chronic primary angle-closure glaucoma. A prospective randomized, crossover study was conducted from April 2005 to July 2005 at Department of Ophthalmology, National Central General Hospital (RSCM Jakarta on subjects with chronic primary angle-closure glaucoma. Subjects were randomly divided into 2 groups: those taking Travoprost once daily and those taking timolol twice daily. Two weeks after treatment with the first drug, the second drug was substituted. Intraocular pressure was recorded before therapy, at day 1, day 7, and day 14. There was a wash out period of three weeks prior to initial treatment and after the cross over. Sixteen subjects (32 eyes met the inclusion criteria and were included in this study. The mean baseline IOP in the Travoprost group was 25.38 ± 3.01 mmHg, while in the timolol group it was 25.88 ± 2.55 mmHg (p=0.354. At day 7, the IOP were consecutively 16.75 + 1.92 mmHg and 21.25 + 3.09 mmHg (p=0.001 and at day 14 IOP were 13.94 + 2.02 mmHg and 19.25 + 2.18 mmHg (p=000. This showed that Travoprost decreased the IOP faster and greater than timolol. The mean baseline IOP was 25.38 ± 3.01 mmHg was decreased to 11.44 ± 1.90 mmHg with Travoprost. In the timolol group, the mean baseline IOP of 25.88 ± 2.55 mmHg was decreased to 6.63 ± 2.25 mmHg. Statistically, Travoprost significantly reduced the IOP faster and greater than timolol (p<0.05.

  4. The Association between Primary Open-Angle Glaucoma and Blood Pressure: Two Aspects of Hypertension and Hypotension

    Hye Jin Chung

    2015-01-01

    Full Text Available Glaucoma is the second leading cause of blindness worldwide. Although the mechanism of the development of primary open-angle glaucoma (POAG is not fully understood, elevated intraocular pressure (IOP is considered the most important risk factor. Several vascular factors have also been identified as risk factors and can lead to hypoperfusion of the optic nerve head and thus may play an important role in the pathogenesis and progression of POAG. The results of the present study suggest that both high and low blood pressure (BP are associated with an increased risk of POAG based on a comprehensive literature review. Elevated BP is associated with elevated IOP, leading to increased risk of glaucoma, but excessive BP lowering in glaucoma patients may cause a drop in ocular perfusion pressure (OPP and subsequent ischemic injury. The relationship between IOP, OPP, and BP suggests that the relationship between BP and glaucoma progression is U-shaped.

Detailed ocular and systemic information was collected on each patient and updated every six months. For this study, blindness was defined as visual acuity of 20/200 or worse and/or visual field less than 20° in either eye. Known risk factors were compared between patients with blindness in at least one eye versus nonblind patients.Results: The patients with blindness had on average: higher intraocular pressure (IOP, mmHg: (24.2 ± 11.2 vs. 22.1 ± 7.7, p = 0.03, wide variation of IOP in the follow-up period (5.9 vs. 4.1 mmHg, p = 0.031, late detection (p = 0.006, poor control of IOP (p < 0.0001, and noncompliance (p < 0.0003. Other known risk factors such as race, age, myopia, family history of glaucoma, history of ocular trauma, hypertension, diabetes, vascular disease, smoking, alcohol abuse, dysthyoidism, and steroid use were not significant.Conclusions: The most critical factors associated with the development of blindness among our patients were: elevated initial IOP, wide variations and poor control of IOP, late detection of glaucoma, and noncompliance with therapy.Keywords: primary open angle glaucoma, blindness, intraocular pressure, risk factors, and noncompliance

  6. Some points of the X-ray pattern of acute viral primary pneumonia caused by acute respiratory disease viruses

    An analysis is made of the results of the X-ray studies as well as of the virological and serological tests in 225 out-patients consulted in the first days of their complaints. A predominance of the viral (70.2%) over the viral-bacterial primary pneumonia is established. The acute viral primary pneumonia are caused mostly by single influenza viruses and more rarely - by single respiratory viruses; in the cases of combined influenza viruses influenza-influenza viruses prevail over the influenza-respiratory ones. The morphological changes in pneumonia due to isolated single influenza viruses involve mostly the interstitium and are projected on X-ray as patchy and stripped densities. The inflamatory changes in pneumonia caused by combined influenza viruses affect both ihe interstitium and the broncho-alveolar substrate of the lungs; they are manifested in two roentgenologic forms: creeping (migrating) and fusing (confluent). In viral-bacterial pneumonia the changes affect mostly the lobe. The right lung and the lower parts of the both lungs are affected in most cases. 5 figs., 21 refs

    Cardoso, Brigite Aguiar; Leal, Rita; Sá, Helena; Campos, Mário

    2016-01-01

    AL amyloidosis is a clonal plasma cell proliferative disorder characterised by extracellular tissue deposits of insoluble fibrils derived from κ or λ immunoglobulin light chains. The most common organs affected by AL amyloidosis are the kidney, presenting with nephrotic syndrome and/or progressive renal dysfunction, and the heart, with restrictive cardiomyopathy. Hepatic deposition of fibrils occurs in half the cases but the liver is rarely the predominantly affected organ. The most common presentation of hepatic amyloidosis is hepatomegaly with elevated alkaline phosphatase. Acute liver failure with cholestasis and jaundice is a rare complication, with a prevalence of approximately 5%, and is usually associated with a worse prognosis. We report a case of a 39-year-old man admitted to our nephrology department with an unusual presentation of primary amyloidosis with nephrotic syndrome and acute liver failure, complicated by obstructive cholestasis resulting in death 2 months after diagnosis.

    Second primary tumor (SPT) is defined as a second tumor that presents either simultaneously or after the diagnosis of an index tumor. Second primary malignancies are the leading cause of death in patients with heritable retinoblastoma (RB). Acute lymphoblastic leukemia (ALL), as SPT in RB patients, is extremely rare. To the best of our knowledge, only five cases of ALL as SPT in patients with RB has been documented in the literature. Herein, we report a case of a 6-year-old girl with bilateral RB, who developed ALL during the course of treatment of RB. This case highlights the importance of reviewing blood investigations regularly to diagnose leukemia as SPT in RB and also the necessity for proper counseling and lifelong follow-up in these patients.

  10. Long-term primary patency prognostic factors after endovascular therapy for acute lower limb ischemia

    Objective: To assess prognostic factors regarding long-term primary patency for patients who underwent intra-arterial thrombolysis and/or adjuvant endovascular techniques due to acute lower limb ischemia. Methods: Consecutive patients with ALI of the lower extremities treated via interventional methods between January 2005 and June 2010 were identified and reviewed (exclude patient suffered from aortic dissection involved artery of lower extremity or trauma). Analyze the potential variables with univariable analysis and only factors associated with long-term primary patency with a P value less than 0.1 in univariable analysis were introduced into the Cox regression mode. Total long-term primary patency and grouped primary patency were assessed using Kaplan-Meier estimation. Results: The analyzed dataset included 107 limbs treated in 101 patients presenting with ALI (class Ⅰ 15, class Ⅱ A 36, class Ⅱ B to Ⅲ 56, according to Rutherford classification). Eight nine limbs were enrolled in follow-up.The mean followup was 34 months (range: 1 to 53 months). Primary patency at 12, 24 and 36 months was 87%, 68% and 55%, respectively. Multivariable analyses identified patients presenting with diabetes mellitus (P=0.00), PAOD (P<0.02) and thrombolysis time (P<0.02) were associated with primary patency. Compare the patency rate of patients with different thrombolysis time, the results showed that the patency rate of the patients thrombolysis time less than 4 d was higher than those more than 4 c. Conclusions: Interventional therapy remains an effective treatment option for patients presenting with lower extremity ALI. Diabetes mellitus and PAOD negatively affect the rates of limb primary patency. Thrombolysis should be limited to <4 days. (authors)

However, there is no study evaluating the clinical differences between patients who have undergone temporary pacing (TP and patients who have not. The present study was designed to investigate whether TP has any prognostic significance in inferior STEMI complicated by complete AVB.Methods: From January 2009 to December 2014, 295 consecutive patients diagnosed with inferior wall STEMI in a university hospital were reviewed. All of them underwent primary percutaneous coronary intervention (PCI. Among the 295 patients, there were 72 patients with complete AVB. The clinical characteristics, procedural data, and long-term major adverse cardiocerebrovascular events were compared in patients with and without TP.Results: Baseline clinical and procedural characteristics were similar between patients with and without TP. Patients with TP were more likely to present with cardiogenic shock; thus, additional interventions were attempted via a femoral approach, as patients received further treatment with intra-aortic balloon pumps and were subjected to additional cardiopulmonary resuscitation. Most cases of complete AVB were primarily caused by right coronary artery occlusion. After a median follow-up period of 344 (range, 105.5–641 days, major adverse cardiocerebrovascular events did not differ between the groups (P=0.528.Conclusion: We conclude that primary PCI without TP is acceptable in complete AVB-complicated acute inferior STEMI. To avoid delay in reperfusion, we suggest that primary PCI should be the first priority therapy rather than treating

    Full Text Available Background: Thrombolysis and Primary Percutaneous Coronary Intervention (PPCI are the standard treatment options for coronary reperfusion in acute ST elevation myocardial infarction (STEMI. We conducted the study to assess the influence of PPCI on the short and intermediate term mortality in acute STEMI, and to identify the high risk subsets that may benefit from PPCI in our population. Methods: Consecutive acute ST elevation myocardial infarction patients admitted to Department of Cardiology, Medical College, Kottayam from November 2008 to March 2010 were allocated to thrombolysis or PPCI as per the standard indications and affordability. Primary endpoint analyzed was in-hospital mortality at 5 days. Secondary endpoints were mortality, angina, re-infarction and Left ventricular dysfunction at 1 month. Statistical analysis was done using chi-square analysis and student ttest. Results:962 consecutive cases of acute STEMI eligible for either PPCI or thrombolysis were included in the study. 135 patients (14% underwent PPCI and 827 (86% were subjected to thrombolysis. 6.7% of the females patients underwent PPCI compared to 15.9% of the males (p=0.001. Mortality in PPCI group was 5.2% compared to 11.2% in thrombolysed group (p=0.032. Inferior wall with Right Ventricular MI had higher mortality than Anterior Wall MI (AWMI (p=0.012. In the thrombolysed group those who presented within 6 hours of onset of pain had lower mortality (8% compared to those who presented >6 hours (14.42% (p=0.003. There was no difference in mortality in PPCI group in the above subsets (p=0.583. Mortality at 1 month was 1.4% in thrombolysed group while there was no mortality in PPCI group (p=0.163. Left ventricular dysfunction was present in 26.8% patients in thrombolysed group compared to 8.8% in PPCI group (p=<0.001.

The patency rate of the infarct-related artery (IRA) in patients in the thrombolysis group was significantly lower than that of patients in the primary stenting group (P0.05).Conclusion Comparing with low dose rt-PA thrombolytic therapy after acute myocardial infarction, primary coronary stenting has a higher patency rate of the IRA, better cardiac function and shorter hospitalization time.

  17. The Role of Emergency Medical Services in Geriatrics: Bridging the Gap between Primary and Acute Care.

    Goldstein, Judah; McVey, Jennifer; Ackroyd-Stolarz, Stacy

    2016-01-01

    Caring for older adults is a major function of emergency medical services (EMS). Traditional EMS systems were designed to treat single acute conditions; this approach contrasts with best practices for the care of frail older adults. Care might be improved by the early identification of those who are frail and at highest risk for adverse outcomes. Paramedics are well positioned to play an important role via a more thorough evaluation of frailty (or vulnerability). These findings may inform both pre-hospital and subsequent emergency department (ED) based decisions. Innovative programs involving EMS, the ED, and primary care could reduce the workload on EDs while improving patient access to care, and ultimately patient outcomes. Some frail older adults will benefit from the resources and specialized knowledge provided by the ED, while others may be better helped in alternative ways, usually in coordination with primary care. Discerning between these groups is a challenge worthy of further inquiry. In either case, care should be timely, with a focus on identifying emergent or acute care needs, frailty evaluation, mobility assessments, identifying appropriate goals for treatment, promoting functional independence, and striving to have the patient return to their usual place of residence if this can be done safely. Paramedics are uniquely positioned to play a larger role in the care of our aging population. Improving paramedic education as it pertains to geriatrics is a critical next step. PMID:26282932

  19. Diode laser trans - scleral cyclo - ablation as a primary surgical treatment for primary open - angle glaucoma after maximum tolerated medical therapy

    The incidence rate and prevalence of glaucoma in Pakistan is similar to that of other dark - colored population countries. Primary trabeculectomy is still a preferred surgical approach. Diode laser is widely accepted as the therapy of choice in severe glaucoma cases. The purpose of this study was to deter-mine the role of Diode Laser Transscleral Cyclo-ablation as a primary surgical treatment option in Primary Open Angle Glaucoma after maximum tolerated medical therapy. This quasi - experimental study was con-ducted at Layton Rahmatullah Benevolent Trust Free Eye Care and Cancer Hospital, Lahore. Sixty patients fulfilling the inclusion criteria were selected from the Glaucoma unit for this study. 25 - 30 burns of Diode Laser were applied to 270 degrees avoiding 3 and 9 O clock positions, 1.5 mm posterior to the limbus. Laser was set at duration of 1 second and power between 1000 and 1500 mw. Patients were followed up for a period of one year. Results: Out of a total of 60 eyes with mean age 52.73 +- 7.40 years, 36 (60%) were male and 24 (40%) were female. The mean pre-operative Intra Ocular Pressure IOP was 41.0 +- 7.0 mmHg (The pre-operative IOP ranged from 28 mmHg to 60 mmHg). The mean post-operative IOP was 18.97 mmHg on day one, 16.75 mmHg at 1 week, 15.68 mmHg at 1 month, 15.00 mmHg at 6 months and by the end of a year it was about 14.15 mmHg (The post-operative IOP ranged from 6 mmHg to 52 mmHg). There was a significant drop of more than 50% of post-operative IOP as compared to pre-operative IOP. Conclusion: Diode Laser Transscleral Cycloablation is a practical, rapid, well - tolerated procedure that provides a significant lowering of intraocular pressure with few complications and can considered as alternative treatment in POAG if medical therapy fails.

    2015-01-01

    Full Text Available Purpose: To evaluate whether prostaglandin (PG analogue use is associated with alterations in keratocyte density and central corneal thickness (CCT in subjects with primary open-angle glaucoma (POAG. Materials and Methods: Thirty-five POAG patients treated with PG analogues for >2 years and 35 control subjects without glaucoma were included in this cross-sectional study. All subjects were underwent CCT measurements using ultrasound pachymetry. Keratocyte densities of each stromal layer were determined by in vivo confocal microscopy. Student′s t-test and Chi-square test were used for statistical evaluations. Correlations between keratocyte densities and CCT were analyzed using Pearson′s correlation analysis. Results: Keratocyte densities in each stromal layer were significantly lower in glaucoma patients receiving PG analogues as compared to those of controls (P < 0.001. The mean CCT was also lower in glaucoma patients (515.2 ± 18.8 μ than control subjects (549.6 ± 21.1 μ, P < 0.001. A positive correlation between keratocyte densities in each stromal layer and CCT was observed in POAG patients. Conclusions: Long-term administration of topical PG analogues may adversely influence keratocyte densities and CCT. Further prospective studies are required clarify the relationship between PG analogues and their effects on the cornea.

    2011-01-01

    Full Text Available Introduction. An altered perfusion of the optic nerve head has been proposed as a pathogenic factor in glaucoma. Objective. To evaluate changes of haemodynamic parameters in the retrobulbar arterial circulation after a decrease of elevated intraocular pressure (IOP in patients with primary open angle glaucoma (POAG. Methods. Twenty-six patients were examined, 14 men and 12 women, 21 up to 50 years old and 5 below, all with previously diagnosed and treated POAG, and all examined at the Eye Clinic, Clinical Centre of Serbia. IOP was measured both with a Goldmann aplanation tonometer and dynamic contour tonometer. Central corneal thickness was measured with ultrasound pachymeter. Imaging of the retrobulbar arterial circulation by colour Doppler was performed at the Neurology Clinic, Clinical Centre of Serbia. It involved measuring of haemodynamic parameters of the ophthalmic artery, central retinal artery, and posterior ciliary arteries. Peak systolic velocity (PSV and end-diastolic velocity (EDV were measured, and resistive index (RI and pulsatility index (PI were calculated. Results. Haemodynamic arterial parameters PSV and EDV in the ophthalmic and central retinal artery after decrease of IOP were lower, while RI and PI were higher. In the posterior ciliary arteries PSV, EDV and PI were lower, and RI was higher. Conclusion. Changes of the retrobulbar arterial circulation after elevated IOP in POAG patients are important for approach and treatment, while the role of vascular factors in the supplement of the optic disc neuroretinal rim could be a key for progression backlash of glaucoma and the radix of neuroprotection.

    Purpose. To investigate macular pigment optical density (MPOD) and its relationship with retinal thickness in primary open angle glaucoma (POAG) patients using the one-wavelength reflectometry method. Methods. A total of 30 eyes from 30 POAG patients (18 males and 12 females, mean age 47.27 ± 16.93) and 52 eyes from 52 controls (27 males and 25 females, mean age 49.54 ± 19.15) were included in this prospective, observational, case-control study. MPOD was measured in a 7-degree area using one-wavelength reflectometry method. Two parameters, max and mean optical density (OD), were used for analyses. Spectral-domain-optical coherence tomography was used to measure retinal thickness, including central retinal thickness (CRT), the macular ganglion cell complex (GCC), and the circumpapillary retinal nerve fiber layer (RNFL). Results. Both maxOD and meanOD were significantly reduced in POAG patients compared with normal subjects (P < 0.001). GCC, CRT, and RNFL thicknesses were also significantly reduced in POAG patients (P < 0.001). GCC thickness had a positive relationship with MPOD. Conclusions. MPOD within the 7-degree area was significantly lower in Chinese POAG patients than in control subjects, and GCC thickness was significantly and positively associated with MPOD. Whether the observed lower MPOD in POAG contributes to the disease process or is secondary to pathological changes caused by the disease (such as loss of ganglion cells) warrants further and longitudinal study.

  4. Goldmann applanation tonometry compared with corneal-compensated intraocular pressure in the evaluation of primary open-angle Glaucoma

    Ehrlich Joshua R

    2012-09-01

    Full Text Available Abstract Background To better understand the role of corneal properties and intraocular pressure (IOP in the evaluation of primary open-angle glaucoma (POAG; and to determine the feasibility of identifying glaucomatous optic neuropathy (GON using IOP corrected and uncorrected for corneal biomechanics. Methods Records from 1,875 eyes of consecutively evaluated new patients were reviewed. Eyes were excluded if central corneal thickness (CCT or Ocular Response Analyzer (ORA measurements were unavailable. Presence or absence of GON was determined based on morphology of the optic disc, rim and retinal nerve fiber layer at the time of clinical examination, fundus photography and Heidelberg Retinal Tomography. Goldmann-applanation tonometry (GAT in the untreated state was recorded and Goldmann-correlated (IOPg and corneal-compensated IOP (IOPcc were obtained using the ORA. Glaucomatous eyes were classified as normal or high-tension (NTG, HTG using the conventional cutoff of 21 mm Hg. One eligible eye was randomly selected from each patient for inclusion. Results A total of 357 normal, 155 HTG and 102 NTG eyes were included. Among NTG eyes, IOPcc was greater than GAT (19.8 and 14.4 mm Hg; p  Conclusions IOPcc may account for measurement error induced by corneal biomechanics. Compared to GAT, IOPcc may be a superior test in the evaluation of glaucoma but is unlikely to represent an effective diagnostic test.

  5. Novel therapeutic approaches to correct retinal metabolic abnormalities in primary open-angle glaucoma and age-related macular degeneration

    K. A. Mirzabekova

    2015-01-01

    Full Text Available Common pathogenic aspects of age-related macular degeneration (AMD and primary open-angle glaucoma (POAG, i.e., the role of free radicals inducing oxidative damage of the retina and optic nerve, are discussed. Factors that activate free radical reactions as well as multilevel antioxidant protection system are reviewed. Data derived from studies on current antioxidants that are used to treat and prevent dry AMD and glaucomatous optic nerve damage are compared. Neuroprotection for glaucoma will be considered soon as a basis for its treatment. B vitamins are generally included into therapeutic algorithms for glaucomatous optic neuropathy. While being metabolic therapeutics, they stimulate adaptive compensatory mechanisms and reduce the severity of various pathological processes, e.g., hypoxia, lipid peroxidation etc. Neurotrophic, antioxidant, and regenerative effects of B vitamins as wells as their involvement in metabolism, myelinsynthesis and other processes are of special importance for ophthalmologists. Currently, several vitamin and mineral supplements that differ in composition, dosage, and schedule are approved in Russia. SuperOptic, a biologically activeadditive, contains more free lutein (10 mg and zeaxanthin (500 μg as well as potent antioxidants (vitamin E and vitamin C, microelements (zinc and copper, and balanced vitamin B complex. These components play an important role in ocular health. SuperOptic can be recommended for the prevention and treatment of AMD and glaucomatous optic nerve damage.

    INK4 locus at chromosome 9p21 has been reported to be associated with primary open angle glaucoma (POAG) and its subtypes along with the associated optic disc parameters across the populations of European, Japanese and African ancestries. The locus encodes three tumor suppressor genes namely CDKN2A, ARF, CDKN2B and a long non-coding RNA CDKN2B-AS1 (also known as ANRIL). Here, we report association study of 34 SNPs from INK4 locus with POAG in a population of Indo-European ancestry from the eastern part of India (350 patients and 354 controls). With 81% power to detect genetic association we observed only nominal association of rs1011970 (uncorrected p = 0.048) with POAG and rs10120688 (uncorrected p = 0.048) in patients without a high intra-ocular pressure (IOP<21 mm of Hg) compared to controls. This study, in contrast to the previous reports, suggests lack of significant genetic association of INK4 locus with POAG in East Indian population which needs to be replicated in larger studies in diverse world populations.

The following parameters were analyzed in-hospital, at 30 days, and 6 months: (a flow in the culprit artery; (b ventricular function; (c combined outcome of death, acute myocardial infarction, and aditional revascularization. METHODS: From November 1997 to June 1999, a longitudinal nonrandomized study with historical data of 137 patients with acute myocardial infarction within the first 12 hours. Patients undergoing primary angioplasty and were divided into 2 groups: those receiving (A abciximab (26 or (B conventional therapy (111. TIMI flow and regional ventricular function estimated by the standard deviation (SD/chordis index were analyzed. RESULTS: At the end of angioplasty, TIMI 3 flow was observed in 76.9% and 83.8% of the patients in groups A and B, respectively (P=0.58. In the reevaluation, patients with TIMI flow <3 showed a 100% improvement in group A and a 33% in group B (P<0.0001. A significant improvement (P<0.0001 in regional ventricular function, by SD/chordis index, occurred in each group; no significant difference between groups however, was observed (29.9% x 20.2%; P=0.58. A nonsignificant reduction in the combined outcome in the in-hospital phase (3.85% A x 9.0% B; P=0.34 and on the 30th day (4.0% x 12.0%; P=0.22 was observed in group A. CONCLUSION: Abciximab improved blood flow. Primary angioplasty improved regional ventricular function independent of antithrombotic therapy. Abciximab showed a trend toward reducing the combined outcome in the in-hospital phase and on the 30th day.

However, histone H3 methylation in these cells has not been characterized. Methods This study examined the methylation status at histone H3 lysine 4 (H3K4 and histone H3 lysine 9 (H3K9 in primary acute leukemia cells obtained from patients and compared with those in the non-leukemia and healthy cells. We further characterized the effect of phenylhexyl isothiocyanate (PHI, Trichostatin A (TSA, and 5-aza-2’-deoxycytidine (5-Aza on the cells. Results We found that methylation of histone H3K4 was virtually undetectable, while methylation at H3K9 was significantly higher in primary human leukemia cells. The histone H3K9 hypermethylation and histone H3K4 hypomethylation were observed in both myeloid and lymphoid leukemia cells. PHI was found to be able to normalize the methylation level in the primary leukemia cells. We further showed that PHI was able to enhance the methyltransferase activity of H3K4 and decrease the activity of H3K9 methyltransferase. 5-Aza had similar effect on H3K4, but minimal effect on H3K9, whereas TSA had no effect on H3K4 and H3K9 methyltransferases. Conclusions This study revealed opposite methylation level of H3K4 and H3K9 in primary human leukemia cells and demonstrated for the first time that PHI has different effects on the methyltransferases for H3K4 and H3K9.

    2016-01-01

    Acute acalculous cholecystitis (AAC) constitutes 5-10% of all cases of cholecystitis in adults, and is even less common in children. The recent literature has described an association between primary Epstein-Barr virus (EBV) infection and AAC, however, it still remains an uncommon presentation of the infection. Most authors advise that the management of AAC in patients with primary EBV infection should be supportive, since the use of antibiotics does not seem to alter the severity or prognosis of the illness. Furthermore, surgical intervention has not been described as necessary or indicated in the management of uncomplicated AAC associated with EBV infection. We report a case of a 16-year-old Lebanese girl with AAC associated with primary EBV infection. She presented to the emergency department, with high-grade fever, fatigue, vomiting and abdominal pain. Liver enzymes were elevated with a cholestatic pattern, and imaging confirmed the diagnosis of AAC. She was admitted to the regular floor, and initial management was conservative. Owing to persistence of fever, antibiotics were initiated on day 3 of admission. She had a smooth clinical course and was discharged home after a total of 9 days, with no complications.

    2016-04-01

    We aimed to assess choroidal thickness and vessel diameter in patients with primary open-angle glaucoma (POAG) using enhanced depth imaging (EDI) optical coherence tomography (OCT) with age-based analysis. Fifty-four patients with a confirmed diagnosis of POAG and 44 age-sex matched healthy subjects were included into the study. A masked physician performed measurements of largest choroidal vessel diameter and choroidal thicknesses (subfoveal, nasal, and temporal) using EDI OCT. Subgroup analyses were performed to compare choroidal measurements based on age (with a cut point of 70 years). The study cohort comprised 54 patients with POAG (mean age of 63.2 ± 8.8 years) and 44 healthy control subjects (mean age of 62.9 ± 8.5 years) (P = 0.870). We found no significant differences in terms of choroidal measurements (P > 0.05) between the glaucoma and control groups. However, in the glaucoma group, patients with an age ≥70 years had significantly thinner subfoveal and nasal choroid compared to those of the patients with  0.05). Choroidal thickness and vessel caliber seem not to differ between patients with POAG and healthy controls. However, an age ≥70 years might be associated with thinning in subfoveal and nasal choroid in patients with POAG. Further studies are needed to elucidate whether choroidal thinning is a cause or result in POAG. PMID:26077882

Methods: A consecutive, prospective series of 82 study eyes with primary open-angle glaucoma and advanced glaucomatous visual field defects were included in this study. All study participants underwent a full ophthalmic examination followed by visual field testing with standard automated perimetry as well as spectral-domain optical coherence tomography (SD-OCT for peripapillary RNFL thickness and Optos wide-field fundus autofluorescence (FAF images. A pattern grid with corresponding locations between functional visual field sectors and structural peripapillary RNFL thickness was aligned to the FAF images at corresponding location. Mean FAF intensity (range: 0 = black and 255 = white of each evaluated sector (superotemporal, temporal, inferotemporal, inferonasal, nasal, superonasal was correlated with the corresponding peripapillary RNFL thickness obtained with SD-OCT. Results: Correlation analyses between sectoral RNFL thickness and standardized FAF intensity in the corresponding topographic retina segments revealed partly significant correlations with correlation coefficients ranging between 0.004 and 0.376 and were statistically significant in the temporal inferior central field (r = 0.324, P = 0.036 and the nasal field (r = 0.376, P = 0.014. Conclusion: Retinal pigment epithelium abnormalities correlate with corresponding peripapillary RNFL damage, especially in the temporal inferior sector of patients with advanced glaucomatous visual field defects.

  13. GALC deletions increase the risk of primary open-angle glaucoma: the role of Mendelian variants in complex disease.

    Yutao Liu

    Full Text Available DNA copy number variants (CNVs have been reported in many human diseases including autism and schizophrenia. Primary Open Angle Glaucoma (POAG is a complex adult-onset disorder characterized by progressive optic neuropathy and vision loss. Previous studies have identified rare CNVs in POAG; however, their low frequencies prevented formal association testing. We present here the association between POAG risk and a heterozygous deletion in the galactosylceramidase gene (GALC. This CNV was initially identified in a dataset containing 71 Caucasian POAG cases and 478 ethnically matched controls obtained from dbGAP (study accession phs000126.v1.p1. (p = 0.017, fisher's exact test. It was validated with array comparative genomic hybridization (arrayCGH and realtime PCR, and replicated in an independent POAG dataset containing 959 cases and 1852 controls (p = 0.021, OR (odds ratio = 3.5, 95% CI -1.1-12.0. Evidence for association was strengthened when the discovery and replication datasets were combined (p = 0.002; OR = 5.0, 95% CI 1.6-16.4. Several deletions with different endpoints were identified by array CGH of POAG patients. Homozygous deletions that eliminate GALC enzymatic activity cause Krabbe disease, a recessive Mendelian disorder of childhood displaying bilateral optic neuropathy and vision loss. Our findings suggest that heterozygous deletions that reduce GALC activity are a novel mechanism increasing risk of POAG. This is the first report of a statistically-significant association of a CNV with POAG risk, contributing to a growing body of evidence that CNVs play an important role in complex, inherited disorders. Our findings suggest an attractive biomarker and potential therapeutic target for patients with this form of POAG.

    Purpose To investigate optic disc perfusion differences in normal, primary open-angle glaucoma (POAG), and normal tension glaucoma (NTG) eyes using optical microangiography (OMAG) based optical coherence tomography (OCT) angiography technique. Design Cross-sectional, observational study. Subjects Twenty-eight normal, 30 POAG, and 31 NTG subjects. Methods One eye from each subject was scanned with a 68 kHz Cirrus HD-OCT 5,000-based OMAG prototype system centered at the optic nerve head (ONH) (Carl Zeiss Meditec Inc, Dublin, CA). Microvascular images were generated from the OMAG dataset by detecting the differences in OCT signal between consecutive B-scans. The pre-laminar layer (preLC) was isolated by a semi-automatic segmentation program. Main Outcome Measures Optic disc perfusion, quantified as flux, vessel area density, and normalized flux (flux normalized by the vessel area) within the ONH. Results Glaucomatous eyes had significantly lower optic disc perfusion in preLC in all three perfusion metrics (p<0.0001) compared to normal eyes. The visual field (VF) mean deviation (MD) and pattern standard deviation (PSD) were similar between the POAG and NTG groups, and no differences in optic disc perfusion were observed between POAG and NTG. Univariate analysis revealed significant correlation between optic disc perfusion and VF MD, VF PSD, and rim area in both POAG and NTG groups (p≤0.0288). However, normalized optic disc perfusion was correlated with some structural measures (retinal nerve fiber layer thickness and ONH cup/disc ratio) only in POAG eyes. Conclusions Optic disc perfusion detected with OMAG was significantly reduced in POAG and NTG groups compared to normal controls, but no difference was seen between POAG and NTG groups with similar levels of VF damage. Disc perfusion was significantly correlated with VF MD, VF PSD, and rim area in glaucomatous eyes. Vascular changes at the optic disc as measured using OMAG may provide useful information for

  16. Comparison of intraocular pressure lowering effect of latanoprost and timolol combination versus latanoprost alone in primary open angle glaucoma

    To compare the intraocular pressure (IOP) lowering effect of topical drug combination (Latanoprost and Timolol) with Latanoprost alone in patients of Primary Open Angle Glaucoma (POAG). Study Design: Randomized controlled Trials (RCT). Place and Duration of Study: Armed Forces Institute of Ophthalmology (AFIO) Rawalpindi from December 2009 to May 2011. Patients and Methods: A total of 240 eyes of 120 patients (68 males and 52 females) were included in the study. The patients were randomized into two groups of 60 each using random numbers table. Group A (60 patients, 120 eyes) were put on topical drug combination of Latanoprost and Timolol eye drops and Group B (60 patients, 120 eyes) were treated with topical Latanoprost eye drops alone. IOP assessments were done at baseline, 2 weeks, 4 weeks and 8 weeks intervals after initiation of treatment. Results: Both the groups were age matched with mean age in Group A was 56.39 ± 8.50 years and in Group B was 55.61 ± 8.95 years (p=0.09). Both groups showed significant IOP decrease from the baseline at each follow up interval. However after 8 weeks of start of treatment, pressure lowering effect in group A (14.73 ± 2.50 mmHg) was significantly more as compared to Group B (9.10 ± 2.51 mmHg) (p<0.001). Conclusion: Combination therapy of Latanoprost and Timolol is more effective as compared to monotherapy with Latanoprost in lowering IOP of patients with POAG. (author)

    2015-01-01

    Full Text Available Purpose: The aim of the present study was to evaluate the effect of surgical peripheral iridectomy (SPI on choroidal thickness in primary angle-closure suspect (PACS eyes. Materials and Methods: This was a prospective observational case series of 30 subjects with PACS. Ocular biometry was performed before SPI (baseline and then 1 week later. Choroid was imaged by enhanced depth imaging optical coherence tomography (EDI-OCT. The choroidal thickness of the subfoveal area at 1 and 3 mm diameter around the fovea was determined. Central anterior chamber depth (ACD, lens thickness (LT, vitreous chamber depth (VCD, and axial length (AL were measured by A-scan ultrasound. Parameters were compared before SPI (baseline and 1 week later. Results: Thirty eyes of 30 patients with mean age of 61.53 ± 7.98 years were studied. There was no significant difference in the choroidal thickness at all macular locations before and after SPI (all P > 0.05. Mean subfoveal choroidal thickness was 279.61 μm ± 65.50 μm before and 274.54 μm ± 63.36 μm after SPI (P = 0.308. There was also no significant change in central ACD, LT, VCD, and LT after SPI (all P > 0.05. Conclusions: SPI does not appear to alter choroidal thickness in PACS eyes, as assessed using EDI-OCT. Long-term follow-up of PACS eyes treated with SPI may provide further insight into the effects of this treatment modality on the choroid.

  18. Clinical effectiveness of brinzolamide 1%-brimonidine 0.2% fixed combination for primary open-angle glaucoma and ocular hypertension.

    Sharma, Sourabh; Trikha, Sameer; Perera, Shamira A; Aung, Tin

    2015-01-01

    The main first-line treatment strategy for glaucoma is to reduce intraocular pressure (IOP) by topical ocular hypotensive medications, but many patients require multiple medications for adequate IOP control. Fixed-combination therapies provide several benefits, including simplified treatment regimens, theoretical improved treatment adherence, elimination of the potential for washout of the first drug by the second, and the reduction in ocular exposure to preservatives. β-Adrenoceptor antagonists (particularly 0.5% timolol) are the most commonly used agents in combination with other classes of drugs as fixed-combination eyedrops, but they are contraindicated in many patients, owing to local allergy or systemic side effects. A fixed-combination preparation without a β-blocker is therefore warranted. This paper reviews the clinical effectiveness of brinzolamide 1% and brimonidine 0.2% fixed combination (BBFC) for use in patients with primary open-angle glaucoma and ocular hypertension. We searched PubMed and the ClinicalTrials.gov registry, and identified three randomized controlled trials comparing BBFC vs its constituents (brimonidine vs brinzolamide), and one comparing BBFC with unfixed brimonidine and brinzolamide. All of the studies demonstrated mean diurnal IOP to be statistically significantly lower in the BBFC group compared with constituent groups and noninferior to that with the concomitant group using two separate bottles. The safety profile of BBFC was consistent with that of its individual components, the most common ocular adverse events being ocular hyperemia, visual disturbances, and ocular allergic reactions. Common systemic adverse effects included altered taste sensation, oral dryness, fatigue, somnolence, and decreased alertness. BBFC seems to be a promising new fixed combination for use in glaucoma patients. However, long-term effects of BBFC on IOP, treatment adherence, and safety need to be determined. PMID:26648686

    Full Text Available Background. Predilection site for the acute myocardial infarction of the right ventricle, (AMI-RV is the upper third of the right coronary artery and for this reason such an infarction is followed by numerous complications, primarily by conduction disorders and very often by sudden and rapid cardiogenic shock development. Methods. Primary percutaneous transluminal coronary angioplasty (PPTCA was performed on three patients in whom the acute infarction of the right ventricular was diagnosed and who had been hospitalized six hours after the beginning of chest pain. In all three patients intracoronary stent was implanted. On the admission patients had been in the threatening cardiogenic shock, with the prominent chest pain and with the elevation of ST-segment in V4R>2 mV. In the course of intervention patients were administered low-molecular intracoronary heparin with direct platelet glycoprotein IIb/IIIa inhibitors (abciximab, according to the established procedure applied in such cases. Results. The complete dilatation of the infarcted artery was established with the signs of reperfusion and the further clinical course was completely normal, there was no heart failure and patients had no subjective difficulties. Conclusion. Invasive approach in the treatment of AMI-RV is justifiable, and possibly the therapy of choice of these patients, providing well trained and equipped team is available.

    2005-05-01

    Full Text Available Abstract Background Rheumatic fever continues to put a significant burden on the health of low socio-economic populations in low and middle-income countries despite the near disappearance of the disease in the developed world over the past century. Antibiotics have long been thought of as an effective method for preventing the onset of acute rheumatic fever following a Group-A streptococcal (GAS throat infection; however, their use has not been widely adopted in developing countries for the treatment of sore throats. We have used the tools of systematic review and meta-analysis to quantify the effectiveness of antibiotic treatment for sore throat, with symptoms suggestive of group A streptococcal (GAS infection, for the primary prevention of acute rheumatic fever. Methods Trials were identified through a systematic search of titles and abstracts found in the Cochrane Central Register of Controlled Trials (Cochrane Library Issue 4, 2003, MEDLINE (1966–2003, EMBASE (1966–2003, and the reference lists of identified studies. The selection criteria included randomised or quasi-randomised controlled trials comparing the effectiveness of antibiotics versus no antibiotics for the prevention of rheumatic fever in patients presenting with a sore throat, with or without confirmation of GAS infection, and no history of rheumatic fever. Results Ten trials (n = 7665 were eligible for inclusion in this review. The methodological quality of the studies, in general, was poor. All of the included trials were conducted during the period of 1950 and 1961 and in 8 of the 10 trials the study population consisted of young adult males living on United States military bases. Fixed effects, meta-analysis revealed an overall protective effect for the use of antibiotics against acute rheumatic fever of 70% (RR = 0.32; 95% CI = 0.21–0.48. The absolute risk reduction was 1.67% with an NNT of 53. When meta-analysis was restricted to include only trials evaluating

    Pérez Rodríguez, A E; González Ochoa, E; Bravo González, J R; Carlos Silva, L; Linton, T

    1992-01-01

    The present work presents the study of morbidity due to acute respiratory infections (ARI) in areas of the town of Lisa in Ciudad Habana, and Isla Juventud (Cuba), to characterize different aspects of morbidity measured by health care attendance and to measure true morbidity. About 90% of consultations for ARI were first-time consultations, while their ratio to further consultations was 5.3. True morbidity rates (TMR), obtained trough active research, ranged from 110.4 to 163.4 cases per 1000 inhabitants, considerably higher than morbidity rates measured by primary care consultations (MRPCC) in the same time period. The true morbidity index (TMI), as measured by the ratio of the two previous rates, ranged from 5 to 15. A high proportion (47.6%) of cases reported no medical care attendance. These results provide approximate estimates of true morbidity in the study area, and allow the establishment of a new control program, also improving epidemiologic surveillance within primary care activities.

    Full Text Available Introduction. Ocular blood flow (OBF disturbances could be involved both in the pathogenesis and in progression of glaucomatous damage. Objective. The aim of the study was to compare the retrobulbar hemodynamic parameters in the ophthalmic artery (OA, central retinal artery (CRA and short posterior cilliary arteries (SPCA after decreasing the elevated intraocular pressure (IOP in primary open-angle glaucoma (POAG patients by using color Doppler imaging (CDI. Methods. We examined 60 patients (21 male and 39 female with diagnosed and treated POAG. Thirtynine patients had increased IOP (>25 mm Hg. Peak-systolic velocity (PSV, end-diastolic velocity (EDV, Pourcelot resistance index (RI, and pulsatility index (PI were assessed in the OA, CRA, and SPCA. IOP was measured both with the Goldmann Applanation tonometer (GAT and with the Dynamic Contour tonometer (DCT, three times respectively. Ocular pulse amplitude (OPA was measured using DCT. Results. The retrobulbar parameters between the baseline and after IOP reduction showed no difference in measurements. After Bonferroni correction (p≤0.0056, alpha/9 statistical significance was recorded only in the following retrobulbar hemodynamic parameters; DCT (29.8±6.2 vs. 15.5±5.0, GAT (33.8±9.0 vs. 15.0±6.6 and OPA measurements (4.3±1.0 vs. 3.0±1.6, as compared to the baseline. There was no correlation between the changes in IOP measured with either DCT or GAT and changes in the hemodynamic parameters (p>0.05 for all. Pearson correlation coefficient (95% CI showed very good correlation for IOP measurements between DCT and GAT: at baseline 0.83 (0.71 to 0.90 and at the end 0.71 (0.55 to 0.83; p0.05. Conclusion. There was a lack of correlation between the changes in IOP measured with either DCT or GAT and the changes in the hemodynamic parameters.

    Highlights: • We suggested the association of XRCC1 gene with the increase risk of POAG development. • We indicated the association of clinical factor and XRCC1, MUTYH, ADPRT and APE1 genes with POAG progression. • We postulated the increase level of oxidative DNA damage in group of patients with POAG in relation to healthy controls. • We suggested the slightly decrease ability to repair of oxidative DNA damage. • This is the first data that showed the role of BER mechanism in POAG pathogenesis. - Abstract: Glaucoma is a leading cause of irreversible blindness in developing countries. Previous data have shown that progressive loss of human TM cells may be connected with chronic exposure to oxidative stress. This hypothesis may suggest a role of the base excision repair (BER) pathway of oxidative DNA damage in primary open angle glaucoma (POAG) patients. The aim of our study was to evaluate an association of BER gene polymorphism with a risk of POAG. Moreover, an association of clinical parameters was examined including cup disk ratio (c/d), rim area (RA) and retinal nerve fiber layer (RNFL) with glaucoma progression according to BER gene polymorphisms. Our research included 412 patients with POAG and 454 healthy controls. Gene polymorphisms were analyzed by PCR-RFLP. Heidelberg Retinal Tomography (HRT) clinical parameters were also analyzed. The 399Arg/Gln genotype of the XRCC1 gene (OR 1.38; 95% CI 1.02–1.89 p = 0.03) was associated with an increased risk of POAG occurrence. It was indicated that the 399Gln/Gln XRCC1 genotype might increase the risk of POAG progression according to the c/d ratio (OR 1.67; 95% CI 1.07–2.61 P = 0.02) clinical parameter. Moreover, the association of VF factor with 148Asp/Glu of APE1 genotype distribution and POAG progression (OR 2.25; 95% CI 1.30–3.89) was also found. Additionally, the analysis of the 324Gln/His MUTYH polymorphism gene distribution in the patient group according to RNFL factor showed that it might

    Wang, Fang; Wu, Zhi-Hong

    2016-01-01

    AIM To compare the efficacy and safety of phacoemulsification (Phaco) against combined phacotrabeculectomy (Phacotrabe) in primary angle-closure glaucoma (PACG) with coexisting cataract. METHODS By searching electronically the PubMed, EMBASE, Scientific Citation Index and Cochrane Library published up from inception to January 2014, all randomized controlled trials that matched the predefined criteria were included. The quality of included trials was evaluated according to the guidelines developed by the cochrane collaboration. And the outcomes estimating efficacy and safety of two different surgical treatments were measured and synthesised by RevMan 5.0. RESULTS Five randomized controlled trials were selected and included in Meta-analysis with a total of 468 patients (468 eyes) with both PACG and cataract. We found that Phacotrabe had a greater intraocular pressure (IOP) lowing effect [preoperative IOP: weighted mean difference (WMD)=0.58, 95% confidence intervals (95% CI, -0.53 to 1.69), P=0.31; postoperative IOP: WMD=1.37, 95% CI (0.45 to 2.28), P=0.003], a lower number of anti-glaucoma medications [ risk ratio (RR) =0.05, 95% CI (0.02 to 0.18), P<0.00001] needed postoperatively and less serious damage of optic nerve [risk ratio (RR)=0.48, 95% CI (0.21 to 1.07), P=0.07], but a higher risk of complications [odds ratio (OR) =0.04, 95% CI (0.01 to 0.16), P<0.00001] compared with Phaco. The rest studies indicated that there had no significantly difference between the two surgical methods for postoperative best-corrected visual acuity (BCVA) [WMD=-0.05, 95% CI (-0.14 to 0.05), P=0.32] and loss of visual field [OR=1.06, 95% CI (0.61 to 1.83), P=0.83]. CONCLUSION Phaco alone compared with Phacotrabe had a better effect in IOP reduction, whereas the security decline. Considering the number of sample size, our results remains to be further studied.

  10. The role of base excision repair in the development of primary open angle glaucoma in the Polish population

    Highlights: • We suggested the association of XRCC1 gene with the increase risk of POAG development. • We indicated the association of clinical factor and XRCC1, MUTYH, ADPRT and APE1 genes with POAG progression. • We postulated the increase level of oxidative DNA damage in group of patients with POAG in relation to healthy controls. • We suggested the slightly decrease ability to repair of oxidative DNA damage. • This is the first data that showed the role of BER mechanism in POAG pathogenesis. - Abstract: Glaucoma is a leading cause of irreversible blindness in developing countries. Previous data have shown that progressive loss of human TM cells may be connected with chronic exposure to oxidative stress. This hypothesis may suggest a role of the base excision repair (BER) pathway of oxidative DNA damage in primary open angle glaucoma (POAG) patients. The aim of our study was to evaluate an association of BER gene polymorphism with a risk of POAG. Moreover, an association of clinical parameters was examined including cup disk ratio (c/d), rim area (RA) and retinal nerve fiber layer (RNFL) with glaucoma progression according to BER gene polymorphisms. Our research included 412 patients with POAG and 454 healthy controls. Gene polymorphisms were analyzed by PCR-RFLP. Heidelberg Retinal Tomography (HRT) clinical parameters were also analyzed. The 399Arg/Gln genotype of the XRCC1 gene (OR 1.38; 95% CI 1.02–1.89 p = 0.03) was associated with an increased risk of POAG occurrence. It was indicated that the 399Gln/Gln XRCC1 genotype might increase the risk of POAG progression according to the c/d ratio (OR 1.67; 95% CI 1.07–2.61 P = 0.02) clinical parameter. Moreover, the association of VF factor with 148Asp/Glu of APE1 genotype distribution and POAG progression (OR 2.25; 95% CI 1.30–3.89) was also found. Additionally, the analysis of the 324Gln/His MUTYH polymorphism gene distribution in the patient group according to RNFL factor showed that it might

  11. Functional alterations of V1 cortex in patients with primary open angle glaucoma using functional MRI retinotopic mapping

    Objective: To evaluate the functional changes of visual cortex (V1) in patients with primary open angle glaucoma (POAG) by fMRI retinotopic mapping technology. Methods: Fifteen POAG patients and 15 healthy volunteers underwent stimulations with fMRI retinotopic mapping stimulus and contrast-reversing checkerboard patterns stimulus on a Siemens Trio 3.0 T MRI whole-body scanner for functional data collection. Comparisons of V1 fMRI responses between the glaucomatous eyes and the healthy eyes of the patients were carried out using paired samples t-test, while independent samples t-test was used to compare V1 fMRI responses and activations between the healthy eyes of patients and the age-, gender- and side- matched eyes of normal people. Differences of V1 cortical functions and visual functions were analyzed by linear correlation analysis when the glaucomatous and the healthy eyes were simulated individually., Results: (1) V1 fMRI responses of the individually stimulated glaucomatous eyes [(1.24±0.72)%] were weaker than those of the healthy eyes [(2.18±0.93)%] (t=4.757, P0.05). (2) Differences of V1 cortical functions were negatively correlated with those of visual functions in the individually stimulated glaucomatous and healthy eyes (r=-0.887, P< 0.01). (3) The activated area indexes of V1 cortexes in the healthy eyes from patients (0.72±0.12) were lower than those in the matched eyes of normal people (0.85±0.09) (t=-3.801, P<0.01) . Conclusion: Cortical function impairment was in accordance with visual function impairment in glaucoma. Located and quantified measurement with fMRI retinotopic mapping was a useful method for clinical follow-up and evaluation of functional alteration of glaucomatous visual cortex, and a potentially useful means of studying trans-synaptic degeneration of visual pathways of in vivo glaucoma.

  2. Endovascular Therapy as a Primary Revascularization Modality in Acute Mesenteric Ischemia

    PurposeTo evaluate endovascular therapy (EVT) as the primary revascularization method for acute mesenteric ischemia (AMI).MethodsA retrospective review was performed on all consecutive patients treated for AMI during a 5-year period (January 2009 to December 2013). EVT was attempted in all patients referred for emergent revascularization. Surgical revascularization was performed selectively after failure of EVT. Patient characteristics, clinical presentation, and outcomes were studied. Failures and complications of EVT were recorded.ResultsFifty patients, aged 79 ± 9 years (mean ± SD), out of 66 consecutive patients with AMI secondary to embolic or thrombotic obstruction of the superior mesenteric artery were referred for revascularization. The etiology of AMI was embolism in 18 (36 %) and thrombosis in 32 (64 %) patients. EVT was technically successful in 44 (88 %) patients. Mortality after successful or failed EVT was 32 %. The rates of emergency laparotomy, bowel resection, and EVT-related complication were 40, 34, and 10 %, respectively. Three out of six patients with failure of EVT were treated with surgical bypass. EVT failure did not significantly affect survival.ConclusionsEVT is feasible in most cases of AMI, with favorable patient outcome and acceptable complication rate

    Full Text Available Abstract The occurrence of acute promyelocytic leukemia (APL in HIV-infected patients has been reported in only five cases. Due to a very small number of reported HIV/APL patients who have been treated with different therapies with the variable outcome, the prognosis of APL in the setting of the HIV-infection is unclear. Here, we report a case of an HIV-patient who developed APL and upon treatment entered a complete remission. A 25-years old male patient was diagnosed with HIV-infection in 1996, but remained untreated. In 2004, the patient was diagnosed with primary central nervous system lymphoma. We treated the patient with antiretroviral therapy and whole-brain irradiation, resulting in complete remission of the lymphoma. In 2006, prompted by a sudden neutropenia, we carried out a set of diagnostic procedures, revealing APL. Induction therapy consisted of standard treatment with all-trans-retinoic-acid (ATRA and idarubicin. Subsequent cytological and molecular analysis of bone marrow demonstrated complete hematological and molecular remission. Due to the poor general condition, consolidation treatment with ATRA was given in March and April 2007. The last follow-up 14 months later, showed sustained molecular APL remission. In conclusion, we demonstrated that a complete molecular APL remission in an HIV-patient was achieved by using reduced-intensity treatment.

  4. Hyperosmolar and methotrexate therapy avoiding surgery in the acute presentation of primary central nervous system lymphoma

    Bryan S Lee

    2014-01-01

    Full Text Available Background: Primary central nervous system lymphoma (PCNSL is an aggressive type of extra-nodal non-Hodgkin lymphoma. Without treatment, PCNSL is associated with significant morbidity and mortality, including rapid neurological deterioration. In contrast to other high-grade intracranial neoplasms, PCNSL is considered to have a high response rate to conventional medical therapy, especially in younger patients, and therefore warrants particular attention in terms of nonsurgical treatment. Case Description: We report a case of the medical management of acute deterioration due to rapidly growing PCNSL with mass effect to highlight the efficacy of temporization with hyperosmolar therapy while awaiting the known rapid effects of dexamethasone and methotrexate (MTX treatment. Surgical intervention was avoided, and tumor response was rapid. The patient had corresponding clinical resolution of symptoms of elevated intracranial pressure with return to neurologic baseline. Conclusions: Despite the evidence that PCNSL responds well to steroids and MTX, the rapidity of onset with which this occurs can vary. In patients presenting with mass effect and rapid neurologic decline, there is little evidence to support medical over surgical intervention. Herein we present an illustrative case of a large PCNSL lesion presenting with rapid decline. With clinical improvement in one day and a 50% reduction in tumor volume over less than seven days, the authors present the specific time frame with which PCNSL responds to medical therapy and a safe strategy for medical temporization.

    2006-01-01

    The observed hard X-ray (HXR) flux spectrum $I(\\epsilon)$ from solar flares is a combination of primary bremsstrahlung photons $I_P(\\epsilon)$ with a spectrally modified component from photospheric Compton backscatter of downward primary emission. The latter can be significant, distorting or hiding the true features of the primary spectrum which are key diagnostics for acceleration and propagation of high energy electrons and of their energy budget. For the first time in solar physics, we use a Green's function approach to the backscatter spectral deconvolution problem, constructing a Green's matrix including photoelectric absorption. This approach allows spectrum-independent extraction of the primary spectrum for several HXR flares observed by the {\\it Ramaty High Energy Solar Spectroscopic Imager} (RHESSI). We show that the observed and primary spectra differ very substantially for flares with hard spectra close to the disk centre. We show in particular that the energy dependent photon spectral index $\\gamm...

  7. Comparison of mortality benefit of immediate thrombolytic therapy versus delayed primary angioplasty for acute myocardial infarction.

    Primary percutaneous coronary intervention (PPCI) yields superior mortality outcomes compared with thrombolysis in ST-elevation acute myocardial infarction (STEMI) but takes longer to administer. Previous meta-regressions have estimated that a procedure-related delay of 60 minutes would nullify the benefits of PPCI on mortality. Using a combined database from randomized clinical trials and registries (n = 2,781) and an independently developed model of mortality risk in STEMI, we developed logistic regression models predicting 30-day mortality for PPCI and thrombolysis by examining the influence of baseline risk on the treatment effect of PPCI and on the hazard of treatment delay. We used these models to solve mathematically for "time interval to mortality equivalence," defined as the PPCI-related delay that would nullify its expected mortality benefit over thrombolysis, and to explore the influence of baseline risk on this value. As baseline risk increases, the relative benefit of PPCI compared with thrombolytic therapy significantly increases (p = 0.002); patients with STEMI at relatively low risk of mortality accrue little or no incremental mortality benefit from PPCI, but high-risk patients benefit greatly. However, as baseline risk increases, the hazard associated with longer treatment-related delay also increases (p = 0.007). These 2 effects are compensatory and yield a roughly uniform time interval to mortality equivalence of approximately 100 minutes in patients who have at least a moderate degree of mortality risk (> approximately 4%). In conclusion, the mortality benefits of PPCI and the hazard of PPCI-related delay depend on baseline risk. Previous meta-regressions appear to have underestimated the PPCI-related delay that would nullify the incremental benefits of PPCI. PMID:17493465

  8. Validation of the Recording of Acute Exacerbations of COPD in UK Primary Care Electronic Healthcare Records.

    Kieran J Rothnie

    Full Text Available Acute Exacerbations of COPD (AECOPD identified from electronic healthcare records (EHR are important for research, public health and to inform healthcare utilisation and service provision. However, there is no standardised method of identifying AECOPD in UK EHR. We aimed to validate the recording of AECOPD in UK EHR.We randomly selected 1385 patients with COPD from the Clinical Practice Research Datalink. We selected dates of possible AECOPD based on 15 different algorithms between January 2004 and August 2013. Questionnaires were sent to GPs asking for confirmation of their patients' AECOPD on the dates identified and for any additional relevant information. Responses were reviewed independently by two respiratory physicians. Positive predictive value (PPV and sensitivity were calculated.The response rate was 71.3%. AECOPD diagnostic codes, lower respiratory tract infection (LRTI codes, and prescriptions of antibiotics and oral corticosteroids (OCS together for 5-14 days had a high PPV (>75% for identifying AECOPD. Symptom-based algorithms and prescription of antibiotics or OCS alone had lower PPVs (60-75%. A combined strategy of antibiotic and OCS prescriptions for 5-14 days, or LRTI or AECOPD code resulted in a PPV of 85.5% (95% CI, 82.7-88.3% and a sensitivity of 62.9% (55.4-70.4%.Using a combination of diagnostic and therapy codes, the validity of AECOPD identified from EHR can be high. These strategies are useful for understanding health-care utilisation for AECOPD, informing service provision and for researchers. These results highlight the need for common coding strategies to be adopted in primary care to allow easy and accurate identification of events.

    2014-01-01

    The gastrointestinal tract is the most common site for extranodal involvement by non-Hodgkin’s lymphoma. However, primary appendiceal lymphomas presenting as perforated acute appendicitis are very rare: they occur in only 0.015% of all gastrointestinal lymphoma cases. The management of this condition is still controversial, and a multimodality approach (e.g., surgery, radiation therapy, and chemotherapy) is the optimal treatment. In these cases, appendiceal non-Hodgkin’s lymphomas typically m...

    2011-05-01

    Full Text Available Abstract Background Glaucoma is the leading cause of irreversible blindness. Although primary open-angle glaucoma is more common, primary angle-closure glaucoma (PACG is more likely to result in irreversible blindness. By 2020, 5·3 million people worldwide will be blind because of PACG. The current standard care for PACG is a stepped approach of a combination of laser iridotomy surgery (to open the drainage angle and medical treatment (to reduce intraocular pressure. If these treatments fail, glaucoma surgery (eg, trabeculectomy is indicated. It has been proposed that, because the lens of the eye plays a major role in the mechanisms leading to PACG, early clear lens extraction will improve glaucoma control by opening the drainage angle. This procedure might reduce the need for drugs and glaucoma surgery, maintain good visual acuity, and improve quality of life compared with standard care. EAGLE aims to evaluate whether early lens extraction improves patient-reported, clinical outcomes, and cost-effectiveness, compared with standard care. Methods/Design EAGLE is a multicentre pragmatic randomized trial. All people presenting to the recruitment centres in the UK and east Asia with newly diagnosed PACG and who are at least 50 years old are eligible. The primary outcomes are EQ-5D, intraocular pressure, and incremental cost per quality adjusted life year (QALY gained. Other outcomes are: vision and glaucoma-specific patient-reported outcomes, visual acuity, visual field, angle closure, number of medications, additional surgery (e.g., trabeculectomy, costs to the health services and patients, and adverse events. A single main analysis will be done at the end of the trial, after three years of follow-up. The analysis will be based on all participants as randomized (intention to treat. 400 participants (200 in each group will be recruited, to have 90% power at 5% significance level to detect a difference in EQ-5D score between the two groups of 0·05

    Full Text Available The objective of this study was to evaluate the effectiveness of acute normovolemic hemodilution (ANH as a sole method of reducing allogenic blood requirement in patients undergoing primary elective valve surgery. One hundred eighty eight patients undergoing primary elective valve surgery were prospectively randomized into two groups: Group I (n=100 acted as control and in Group II (n=88 autologous blood was removed (10% of estimated blood volume in patients with hemoglobin (Hb > 12g% and 7% when the Hb was < 12g% in the pre-cardiopulmonary bypass (CPB period for subsequent re-transfusion after protamine administration. The autologous blood withdrawn was replaced simultaneously with an equal volume of hydroxyl-ethyl starch solution. Banked blood was transfused in both the groups when Hb was ≤6g % on CPB and ≤8g% after CPB. Platelets were transfused when the count fell to < 100´10 9 /L and fresh frozen plasma (FFP was transfused whenever there was diffuse bleeding with laboratory evidence of coagulopathy. The two groups were comparable as regards demographic data, type of surgical procedures performed, duration of CPB and ischemia, duration of elective ventilation and re-exploration for excessive bleeding. The autologous blood withdrawn in patients with Hb≥12g% was 288.3±69.4 mL and 244.4±41.3 mL with Hb < 12g% (P=NS. The Hb concentration (g % was comparable pre-operatively (Group I= 12.1±1.6, Group II= 12.4±1.4, on postoperative day 1 (Group I =10.3±1.1, Group II= 10.6±1.2 and day 7 (Group I = 10.9±1.5, Group II=10.4±1.5. However, the lowest Hb recorded on CPB was significantly lower in Group II (Group I =7.7±1.2, Group II=6.7±0.9, P < 0.05. There was no difference in the chest tube drainage (Group I =747.2±276.5 mL, Group II=527.6±399.5 mL, blood transfusion (Group I=1.1±1.0 units vs. Group II=1.3±1.0 units intra-operatively and Group I=1.7±1.2 units vs. Group II=1.7±1.4 units post-operatively and FFP transfusion (Group I

    2012-01-01

    Abstract Background Primary open-angle glaucoma (POAG) is one of the leading causes of blindness in the United States and worldwide. While lowering intraocular pressure (IOP) has been proven to be effective in delaying or preventing the onset of POAG in many large-scale prospective studies, one of the recent hot topics in glaucoma research is the effect of IOP fluctuation (IOP lability) on the risk of developing POAG in treated and untreated subjects. Method In this paper, we analyzed data fr...

  17. Compton backscattered and primary X-rays from solar flares: angle dependent Green's function correction for photospheric albedo

    Kontar, E. P.; MacKinnon, A. L.; Schwartz, R. A.; Brown, J. C.

    2006-02-01

    The observed hard X-ray (HXR) flux spectrum I(ɛ) from solar flares is a combination of primary bremsstrahlung photons I_P(ɛ) with a spectrally modified component from photospheric Compton backscatter of downward primary emission. The latter can be significant, distorting or hiding the true features of the primary spectrum which are key diagnostics for acceleration and propagation of high energy electrons and of their energy budget. For the first time in solar physics, we use a Green's function approach to the backscatter spectral deconvolution problem, constructing a Green's matrix including photoelectric absorption. This approach allows spectrum-independent extraction of the primary spectrum for several HXR flares observed by the Ramaty High Energy Solar Spectroscopic Imager (RHESSI). We show that the observed and primary spectra differ very substantially for flares with hard spectra close to the disk centre. We show in particular that the energy dependent photon spectral index γ (ɛ)=-d log I/d log ɛ is very different for I_P(ɛ) and for I(ɛ) and that inferred mean source electron spectra F(E) differ greatly. Even for a forward fitting of a parametric F(E) to the data, a clear low-energy cutoff required to fit I(ɛ) essentially disappears when the fit is to I_P(ɛ) - i.e. when albedo correction is included. The self-consistent correction for backscattered photons is thus shown to be crucial in determining the energy spectra of flare accelerated electrons, and hence their total number and energy.

  18. The short-term out-come of primary percutaneous coronary intervention for patients with acute myocardial infarction

    Objective: To evaluate the efficacy of primary percutaneous coronary intervention (PCI) for acute myocardial infarction. Methods: 63 patients with acute myocardial infarction were treated by primary PCI within 12 hour from onset and were followed up for one to fourteen months. Results: Procedure was successed in 61 patients (96.8%). Three patients received only primary angioplasty and 58 patients received stent implantation. All of them gained TIMI III grade perfusion flow. Non-perfusion flow occurred in five patients but their flows were improved by intracoronary urokinase infusion. Ventricular tachycardia and fibrillation happened in five patients, and were converted to sinus rhythm by defibrillation in four and one died. Two of the five patients complicated with cardiogenic shock, with one died on 1st day and the other on 4th day after successful PCI, respectively. Main cardiac events occurred in five patients (17%) during follow-up with two sudden death, one reinfarction and repeated PCI, one received selective CABG and on PCI due to intrastent restenosis. Conclusions: Primary PCI could provide higher successful rate of reperfusion with low hospital mortality and good short-term prognosis. (authors)

  1. Delineation of QRS offset by instantaneous changes in ECG vector angle can improve detection of acute inferior myocardial infarctions.

    Starc, Vito; Schlegel, Todd T

    2016-01-01

    We developed an automated new method for determining QRS offset, based on angular velocity (AV) changes around the QRS loop, and compared the method's performance to that of manual and more established automated methods for determining QRS offset in both healthy subjects and patients with acute myocardial infarction (AMI). Specifically, using Frank leads reconstructed from standard 12-lead ECGs, we determined AV in the direction of change raised to the 4th power, d(t). We found that the d(t)-determined AV transition (ΔAV) nearly coincided with manually determined QRS offset in healthy subjects, and in 27 patients with anterior AMI. However, in 31 patients with inferior AMI, ΔAV typically preceded that of QRS offset determined by the established automated methods, and by more than 10ms in 32% of cases. While this "ΔAV precedence" coincided with diagnostic ST elevation in only a minority of patients with recent inferior AMI, the use of ΔAV precedence as a complement to traditional determination of ST elevation increased the sensitivity for detecting inferior AMIs from 23 to 42%.

  7. Primary sensory and motor cortex function in response to acute muscle pain: A systematic review and meta-analysis.

    Burns, E; Chipchase, L S; Schabrun, S M

    2016-09-01

    Acute muscle pain has both motor and sensory consequences, yet the effect of muscle pain on the primary sensory (S1) and motor (M1) cortices has yet to be systematically evaluated. Here we aimed to determine the strength of the evidence for (1) altered activation of S1/M1 during and after pain, (2) the temporal profile of any change in activation and (3) the relationship between S1/M1 activity and the symptoms of pain. In September 2015, five electronic databases were systematically searched for neuroimaging and electrophysiological studies investigating the effect of acute experimental muscle pain on S1/M1 in healthy volunteers. Demographic data, methodological characteristics and primary outcomes for each study were extracted for critical appraisal. Meta-analyses were performed where appropriate. Twenty-five studies satisfied the inclusion criteria. There was consistent evidence from fMRI for increased S1 activation in the contralateral hemisphere during pain, but insufficient evidence to determine the effect at M1. Meta-analyses of TMS and EEG data revealed moderate to strong evidence of reduced S1 and corticomotor excitability during and following the resolution of muscle pain. A comprehensive understanding of the temporal profile of altered activity in S1/M1, and the relationship to symptoms of pain, is hampered by differences in methodological design, pain modality and pain severity between studies. Overall, the findings of this review indicate reduced S1 and corticomotor activity during and after resolution of acute muscle pain, mechanisms that could plausibly underpin altered sensorimotor function in pain. WHAT DOES THIS REVIEW ADD?: We provide the first systematic evaluation of the primary sensory (S1) and motor (M1) cortex response to acute experimental muscle pain in healthy volunteers. We present evidence from a range of methodologies to provide a comprehensive understanding of the effect of pain on S1/M1. Through meta-analyses we evaluate the strength

  8. Pro-apoptotic activity of α-bisabolol in preclinical models of primary human acute leukemia cells

    2011-04-01

    Full Text Available Abstract Background We previously demonstrated that the plant-derived agent α-bisabolol enters cells via lipid rafts, binds to the pro-apoptotic Bcl-2 family protein BID, and may induce apoptosis. Here we studied the activity of α-bisabolol in acute leukemia cells. Methods We tested ex vivo blasts from 42 acute leukemias (14 Philadelphia-negative and 14 Philadelphia-positive B acute lymphoid leukemias, Ph-/Ph+B-ALL; 14 acute myeloid leukemias, AML for their sensitivity to α-bisabolol in 24-hour dose-response assays. Concentrations and time were chosen based on CD34+, CD33+my and normal peripheral blood cell sensitivity to increasing α-bisabolol concentrations for up to 120 hours. Results A clustering analysis of the sensitivity over 24 hours identified three clusters. Cluster 1 (14 ± 5 μM α-bisabolol IC50 included mainly Ph-B-ALL cells. AML cells were split into cluster 2 and 3 (45 ± 7 and 65 ± 5 μM IC50. Ph+B-ALL cells were scattered, but mainly grouped into cluster 2. All leukemias, including 3 imatinib-resistant cases, were eventually responsive, but a subset of B-ALL cells was fairly sensitive to low α-bisabolol concentrations. α-bisabolol acted as a pro-apoptotic agent via a direct damage to mitochondrial integrity, which was responsible for the decrease in NADH-supported state 3 respiration and the disruption of the mitochondrial membrane potential. Conclusion Our study provides the first evidence that α-bisabolol is a pro-apoptotic agent for primary human acute leukemia cells.

    2016-01-01

    Purpose Relatively little data exist regarding the outcomes of children with primary infantile glaucoma presenting with acute corneal hydrops. The aim of our study was to determine the surgical outcome of children of infantile glaucoma who presented with acute corneal hydrops. Methods In total, 38 eyes of 31 consecutive children of infantile glaucoma presented with acute corneal hydrops who underwent primary combined trabeculotomy-trabeculectomy (CTT) by a single surgeon from January 1990 to December 2012 at the LV Prasad Eye Institute (LVPEI), a tertiary eye care centre in Southern India were enrolled in this retrospective study. Primary outcome measures were intraocular pressure (IOP) control (IOP ≤ 16 mmHg under anaesthesia or IOP ≤ 21 mmHg without anaesthesia) and clearance of corneal edema. Secondary outcome measures were visual acuity (VA), corneal diameter, bleb appearance, intraoperative and postoperative complications. Results Mean age at presentation was 6.4 months (range, 2–11 months) and seven eyes (23%) had bilateral affliction. At presentation, all eyes (100%) had moderate to severe degree of corneal edema with a mean preoperative IOP of 25.6 ±5.1 mmHg. Postoperatively, the IOP reduced to 12.0 ± 3.8 mmHg (difference = -13.6, 95% CI = -15.7 to -11.5, t = -13.18, pastigmatism was present in 28 eyes (74%), the commonest being compound myopic astigmatism (75%) followed by simple myopic astigmatism (21%). Normal VA (best-corrected VA; BCVA ≥ 20/60) was achieved in 44.4% of the eyes and 22.2% eyes had low vision (BCVA, <20/60 to 20/400). Complete success (IOP control and clearance of corneal oedema) was obtained in 94.7% eyes. There were no significant intraoperative or postoperative complications. Two thirds of the patients showed low, elevated functional filtering bleb. No patient had any bleb leak, blebitis or bleb related endophthalmitis. The median follow-up was 36 months (range 2–228 months). Conclusions Primary CTT is safe and effective

    Sarnat-Kucharczyk, Monika; Rokicki, Wojciech; Zalejska-Fiolka, Jolanta; Pojda-Wilczek, Dorota; Mrukwa-Kominek, Ewa

    2016-01-01

    Background The aim of this article was to describe the role of ceruloplasmin and to report preliminary results of ceruloplasmin concentrations in patients with primary open-angle glaucoma (POAG) with cataract and in patients with only cataract. Glaucoma, a neurodegenerative disease, is a heterogeneous group of conditions characterized by loss of retinal ganglion cells (RGC), their axons, progressive optic nerve damage, and visual field deterioration. Material/Methods The POAG group included 30 patients and the cataract group included 25 patients. Results Ceruloplasmin plays an essential role in iron metabolism and inactivating free radicals. In the presented pilot study, serum ceruloplasmin level was lower in the POAG group in comparison to the group with only cataract. Conclusions In treating persistent inflammation in the course of glaucoma, antiglaucoma drugs may increase the permeability of the blood-ocular barrier, which may be connected with the lower concentration of serum ceruloplasmin in the glaucoma patients group.

    Full Text Available Ghana is the most affected country in Africa as far as glaucoma is concerned. This study therefore aims at determining the efficacy of the National Health Insurance Scheme listed anti-glaucoma drugs in the management of primary open-angle glaucoma in Ghana. This retrospective survey was carried out at the Golden Jubilee Eye Centre of St Michael’s Catholic Hospital, Pramso in the Bosomtwi Atwima Kwanwoma District of the Ashanti Region of Ghana from January 2008 to De-cember 2010. By random and purposive sampling, 141 patient folders (35.25% of total folders stud-ied were selected and data on drugs and intra-ocular pressure measurements for eight consecutive visits to the centre were recorded and analyzed appropriately. The outcome of primary open-angle glaucoma in the study was not gender sensitive but increased with age (majority 70 – 79 years. While Timolol, in monotherapy, reduced but not significantly (p > 0.05 the initial mean intra-ocular pressure measurements, Latanoprost reduced the initial mean intra-ocular pressure very significantly (p ≤ 0.001. Combination therapies involving Latanoprost and listed anti-glaucoma drugs reduced intra-ocular pressure significantly than combination therapies involving NHIS-listed drugs only (p ≤ 0.01. Though the National Health Insurance Scheme listed anti-glaucoma drug show intra-ocular pressure reduction in mono- and combination therapies, reduction by Lat-anoprost and combination of Latanoprost with the NHIS-listed drugs is very much significant. An addition of Latanoprost to the National Health Insurance Scheme list of anti-glaucoma medica-tions would therefore be very beneficial to glaucoma patients in Ghana.

    Acute myocardial infarction(AMI) is still the leading factor causing crippling and death in cardiovascular disease.Percutaneous coronary intervention(PCI) can significantly reduce inpatient mortality and incidence of complication.But owing to the existence of restenosis,in-stent thrombosis,etc.,recurrent post-PCI cardiovascular events and high repeatability of hospitalization,as well as its crippling rate and mortality, remain a serious threat to the society and the patients' family.Therefore,the apprais...

  1. Primary injuries and secondary organ failures in trauma patients with acute kidney injury treated with continuous renal replacement therapy.

    Beitland, Sigrid; Os, Ingrid; Sunde, Kjetil

    2014-01-01

    Background. Acute kidney injury (AKI) treated with continuous renal replacement therapy (CRRT) is a severe complication in trauma patients. The aim of the study was to assess primary traumatic injuries and secondary organ failures in severe posttraumatic AKI. Methods. Retrospective review of adult trauma patients admitted to the trauma centre at Oslo University Hospital Ullevål. Injury severity score (ISS) was used to assess the severity of primary injuries, and sequential organ failure assessment (SOFA) score was utilized to measure secondary organ failures. Results. Forty-two (8%) of 506 trauma patients admitted to intensive care unit developed AKI treated with CRRT, whereof 40 (95%) suffered blunt trauma mechanisms. Patients had extensive primary organ injuries with median (interquartile range) ISS 36 (27-49). The majority of the patients had respiratory (93% intubated) and cardiovascular (67% with inotropic and/or vasoactive medication) failure within 24 hours after admission. AKI was often part of multiple organ failure, most frequently respiratory and cardiovascular failure, affecting 33 (75%) and 30 (71%) of the patients, respectively. Conclusion. Trauma patients with AKI undergoing CRRT often had severe primary injuries due to blunt trauma. Most of them suffered from secondary multiple organ failure concomitant to AKI. PMID:25587490

  3. Clinical outcomes of patients with major bleeding after primary coronary intervention for acute ST-segment elevation myocardial infarction

    Objective: To evaluate the clinical outcomes of patients complicated with major bleeding after primary coronary intervention (PCI) for acute ST-segment elevation myocardial infarction (STEMI). Methods: During the period of January 2004-January 2008, primary PCI was performed in 412 consecutive patients with acute STEMI at Shanghai Ruijin Hospital. The clinical data were retrospectively analyzed. Major adverse cardiac events (MACE), including death, reoccurrence of myocardial infarction and target vessel revascularization, in patients with major bleeding were compared with that in patients without major bleeding. Results: Compared to patients without bleeding, the patients with bleeding were older (70.0 ± 8.9 years vs 64.9 ± 12.7 years, P=0.04), mainly the females (51.9% vs 23.1%, P=0.001) and treated more often with glycoprotein (GP) IIb / IIIa receptor inhibitor (88.9% vs 69.4%, P=0.03) or intra-aortic balloon pump (7.4% vs 1.3%, P=0.02). In-hospital and one-year MACE rate in the patients with bleeding was 18.5% and 37.0% respectively,which were significantly higher than that in the patients without bleeding (5.7% and 14.3%, with P=0.008 and P=0.002, respectively). Multivariate analysis indicated that patient aged over 70 years, feminine gender and use of GP IIb/IIIa receptor inhibitor were independent predictors for the occurrence of major bleeding. The occurrence of major bleeding after primary PCI was significantly correlated with MACE occurred within one year after the procedure (OR 2.79, 95% CI: 2.21-5.90, P<0.001). Conclusion: In patients with acute STEMI, the occurrence of major bleeding after primary PCI is closely linked to the increased MACE rate within one year after the treatment.Feminine gender, aged patient and use of GPIIb/IIIa receptor inhibitor are independent predictors to increase the danger of major bleeding.

    2016-02-01

    Solid-state 13C nuclear magnetic resonance (NMR) measurements were performed on the hexagonal columnar and cubic phases of an acute-angle banana-shaped molecule, N(1,7)-S30. In the hexagonal columnar phase, three peaks appear at the NMR chemical shifts assigned to the internal methylene carbons of alkyl tails, indicating that the two alkyl tails have different packing structures, and one of the tails has two different conformations within a single molecule. Combined cross-polarization/magic-angle spinning and pulse saturation transfer/magic-angle spinning measurements show that one of the alkyl chains is located inside and the other is located outside the columnar structure. In the cubic phase, pulse saturation transfer/magic-angle spinning measurement shows that only one peak appears at the NMR chemical shifts assigned to the internal methylene carbons of alkyl tails, indicating that both of the alkyl chains are located outside the cubic structure.

    2006-01-01

    Glaucoma is closely related to elevation of intraocular pressure (IOP). Many studies have done on the effect of chronic elevation of IOP on the retina and optic nerve, but less attention was paid to the effect of acute elevated IOP. Here we briefly review experimental studies on functional changes of the visual system from the retina to the visual cortex under acute elevated IOP condition, which is similar to that of acute primary angle-closure glaucoma.

  6. High-Grade Acute Organ Toxicity as a Positive Prognostic Factor in Primary Radiochemotherapy for Anal Carcinoma

    Purpose: To test for a possible correlation between high-grade acute organ toxicity during primary radiochemotherapy and treatment outcome for patients with anal carcinoma. Methods and Materials: From 1991 to 2009, 72 patients with anal carcinoma were treated at our department (10 patients had stage I, 28 patients had stage II, 11 patients had stage IIIA, and 13 patients had stage IIIB cancer [Union Internationale Contre le Cancer criteria]). All patients received normofractionated (1.8 Gy/day, five times/week) whole-pelvis irradiation including iliac and inguinal lymph nodes with a cumulative dose of 50.4 Gy. Concomitant chemotherapy regimen consisted of two cycles of 5-fluorouracil (1,000 mg/m2total body surface area (TBSA)/day as continuous intravenous infusion on days 1-4 and 29-32) and mitomycin C (10 mg/m2/TBSA, intravenously on days 1 and 29). Toxicity during treatment was monitored weekly, and any incidence of Common Toxicity Criteria (CTC) grade of ≥3 for skin reaction, cystitis, proctitis, or enteritis was assessed as high-grade acute organ toxicity for later analysis. Results: We found significant correlation between high-grade acute organ toxicity and overall survival, locoregional control, and stoma-free survival, which was independent in multivariate analysis from other possible prognostic factors: patients with a CTC acute organ toxicity grade of ≥3 had a 5-year overall survival rate of 97% compared to 30% in patients without (p < 0.01, multivariate analysis; 97% vs. 48%, p = 0.03 for locoregional control, and 95% vs. 59%, p = 0.05 for stoma-free survival). Conclusions: Our data indicate that normal tissue and tumor tissue may behave similarly with respect to treatment response, since high-grade acute organ toxicity during radiochemotherapy showed itself to be an independent prognostic marker in our patient population. This hypothesis should be further analyzed by using biomolecular and clinical levels in future clinical trials.

  7. [The condition of endothelium and hemostasis in patients with primary diagnosed acute lymphoblast leucosis].

    Vladimorova, S G; Skol'skaia, O Iu; Tarasova, L N; Dokshina, I A

    2012-08-01

    The evaluation of state of endothelium and plasma hemostasis, thrombocytopenia degree, rate of thrombo-hemorrhagic complications in adult patients with acute lymphoblastic leucosis in the period of disease manifestation was made. The thrombosis developed in 1 out of 24 (4.2%) examined patients, hemorrhagic syndrome in 11 out of 24 (45.8%) examined patients. The last case is closely linked with severity of thrombocytopenia occurred in patients with number of thrombocytes less than 50 x 109/l. At the same time, high correlation between number of leukemic cells and level of B-dimers (rs = 0.703) testifies that the leucosis process activates intravascular thrombus formation. The higher content of B-dimers in 100% of patients validates this assumption. The high levels of soluble thrombo-modulin and von Willebrand factor indicate the loss of thromboresistance by vessel endothelium and the activation of prothrombin mechanisms. The statistically valid coefficients of correlation between concentrations of thrombomodulin and D-dimers (rs = 0.598) and the level of von Willebrand factor and severity of hemorrhagic syndrome prove that disorders of blood coagulation under acute lymphoblast leucosis occur with active involvement of endothelium.

    Objective Anemia is associated with high mortality and poor prognosis after acute coronary syndrome (ACS). Increased red cell distribution width (RDW) is a strong independent predictor for adverse outcomes in ACS. The common underlying mechanism for anemia and increased RDW value is iron deficiency. It is not clear whether serum iron deficiency without anemia affects left ventricular (LV) performance after primary angioplasty for acute myocardial infarction (AMI).

    Full Text Available Background: This study reported the incidence and prognostic outcome of chronic obstructive lung disease (COPD patients with acute ST-segment elevation myocardial infarction (STEMI undergoing primary percutaneous coronary intervention (PCI. Methods: Between January 2002 and May 2011, totally 1554 consecutive patients who experienced STEMI undergoing primary PCI were enrolled into the study. Results: Of the 1554 patients, 124 (9.7% with diagnosis of COPD and 1430 (90.3% without COPD were categorized into group 1 and group 2. Although no difference in in-hospital mortality was noted between the two groups (p = 0.726. However, the hospitalization duration was notably longer (p = 0.003, the incidences of recurrent MI and re-hospitalization for congestive heart failure were significantly higher in group 1 than in group 2 (all p < 0.02. Although Kaplan-Meier analysis demonstrated that the incidence of freedom from one-year major adverse clinical outcome (MACO (defined as recurrent MI, re-admission for congestive heart failure was significantly lower in group 1 than group 2 (p = 0.012, multivariate Cox regression analysis showed COPD was not an independent predictor of MACO-free time after adjusting traditional risk factors. Conclusion: COPD was not an independent predictor of short-term and medium-term MACO in patients with STEMI undergoing primary PCI.

    Methotrexate is being used for many years in the treatment of chronic medical disorders e.g. rheumatoid arthritis since 1951. It has been associated with various systemic toxicities and complications including bone marrow suppression and lymphomas. The development of leukaemia in a patient of chronic rheumatoid arthritis is either related with the primary disease or due to the drugs which are used in the treatment like cyclophosphamide. In our present case, a 70-year-old female who was a known case of Rheumatoid Arthritis (RA) and was on methotrexate once a week orally for the past 20 years presented with complaints of loss of appetite, loss of weight and anaemia since 2 months. After thorough examination and investigation, she was diagnosed with acute myeloid leukaemia (AML-M4) with bilateral chest consolidation. PMID:27134915

    2011-11-01

    Full Text Available Abstract Background Given the costs associated with the management of musculoskeletal pain in primary care, predicting the course of these conditions remains a research priority. Much of the research into prognostic indicators however considers musculoskeletal conditions in terms of single pain sites whereas in reality, many patients present with pain in more than one site. The aim of this study was to identify prognostic factors for early improvement in primary care consulters with acute and persistent musculoskeletal conditions across a range of pain sites. Methods Consecutive patients with a new episode of musculoskeletal pain completed self-report questionnaires at baseline, and then again at the 4/5th treatment visit, and if they were still consulting, at the 10th visit. The outcome was defined as patient self-report improvement sufficient to make a meaningful difference. Independent predictors of outcome were identified using multivariate regression analyses. Results Acute (th visit. Several variables at baseline were associated with improvement at the 4/5th visit, but the predictive models were weak and unable to discriminate between patients who were improved and those who were not. In contrast, it was possible to elicit a predictive model for improvement later on at the 10th visit, but only in patients with persistent pain. Being employed, reporting a decline in work fear-avoidance behaviour at the 4/5th visit, and being better by the 4/5th visit, were all independently associated with improvement. This model accounted for 34.3% (p Conclusions We were unable to identify baseline characteristics that predicted early outcome in musculoskeletal pain patients. However, early self-reported improvement and decline in work fear-avoidance behaviour as predictors of later improvement highlighted the importance of speedy recovery in persistent musculoskeletal pain consulters. Our findings reinforce the elusive nature of baseline predictors, and

    Full Text Available Purpose: To compare ocular biometric parameters in primary angle closure suspects (PACS, primary angle closure glaucoma (PACG and acute primary angle closure (APAC. Methods: This cross-sectional study was performed on 113 patients including 33 cases of PACS, 45 patients with PACG and 35 subjects with APAC. Central corneal thickness (CCT, axial length (AL, anterior chamber depth (ACD and lens thickness (LT were measured with an ultrasonic biometer. Lens-axial length factor (LAF, relative lens position, corrected ACD (CACD and corrected lens position were calculated. The parameters were measured bilaterally but only data from the right eyes were compared. In the APAC group, biometric parameters were also compared between affected and unaffected fellow eyes. Logistic regression analysis was performed to identify risk factors. Results: No statistically significant difference was observed in biometric parameters between PACS and PACG eyes, or between affected and fellow eyes in the APAC group (P>0.05 for all comparisons. However, eyes with APAC had thicker cornea (P=0.001, thicker lens (P<0.0001, shallower ACD (P=0.009, shallower CACD (P=0.003 and larger LAF (P<0.0001. Based on ROC curve analysis, lower ACD, and larger LT, LAF and CCT values were associated with APAC. In the APAC group, LAF (P<0.0001 and CCT (P=0.001 were significant risk factors. Conclusion: This study revealed no significant difference in biometric characteristics in eyes with PACS and PACG. However, larger LAF and CCT were predictive of APAC.

    Background Drug-eluting stent (DES) has been used widely for the treatment of patients with acute coronary syndrome with or without diabetes mellitus during percutaneous coronary intervention (PCI), but its long-term safety and efficacy in diabetic patients with acute ST elevation myocardial infarction (STEMI) remain uncertain. This study aimed to investigate the clinical outcomes after primary coronary intervention with DES implantation for diabetic patients with acute STEMI, compared with non-diabetic counterparts.Methods From December 2004 to March 2006, 56 consecutive diabetic patients (diabetic group) and 170 non-diabetic patients (non-diabetic group) with acute STEMI who underwent primary PCI with DES implantation in 3 hospitals were enrolled. Baseline clinical, angiographic, and procedural characteristics, as well as occurrence of major adverse cardiac event (MACE) including cardiac death, non-fatal recurrent myocardial infarction (re-MI) and target vessel revascularization (TVR) during hospitalization and one-year clinical follow-up were compared between the two groups.Results Patients in diabetic group were more hyperlipidemic (69.6% and 51.8%, P=0.03) and had longer time delay from symptom onset to admission ((364±219) minutes and (309±223) minutes,P=0.02) than those in non-diabetic group.The culprit vessel distribution, reference vessel diameter, and baseline TIMI flow grade were similar between the two groups, but multi-vessel disease was more common in diabetic than in non-diabetic group (82.1% and 51.2%, P<0.001).Despite similar TIMI flow grades between the two groups after stenting, the occurrence of TIMI myocardial perfusion grade (TMPG)≥2 was lower in diabetic group (75.0% vs 88.8% in non-diabetic groups, P=0.02). The MACE rate was similar during hospitalization between the two groups (5.4% vs 3.5%, P=0.72), but it was significantly higher in diabetic group (16.1%) during one-year follow-up, as compared with non-diabetic group (6.5%, P=0

  5. Exome Sequencing Identifies a Missense Variant in EFEMP1 Co-Segregating in a Family with Autosomal Dominant Primary Open-Angle Glaucoma.

    Donna S Mackay

    Full Text Available Primary open-angle glaucoma (POAG is a clinically important and genetically heterogeneous cause of progressive vision loss as a result of retinal ganglion cell death. Here we have utilized trio-based, whole-exome sequencing to identify the genetic defect underlying an autosomal dominant form of adult-onset POAG segregating in an African-American family. Exome sequencing identified a novel missense variant (c.418C>T, p.Arg140Trp in exon-5 of the gene coding for epidermal growth factor (EGF containing fibulin-like extracellular matrix protein 1 (EFEMP1 that co-segregated with disease in the family. Linkage and haplotype analyses with microsatellite markers indicated that the disease interval overlapped a known POAG locus (GLC1H on chromosome 2p. The p.Arg140Trp substitution was predicted in silico to have damaging effects on protein function and transient expression studies in cultured cells revealed that the Trp140-mutant protein exhibited increased intracellular accumulation compared with wild-type EFEMP1. In situ hybridization of the mouse eye with oligonucleotide probes detected the highest levels of EFEMP1 transcripts in the ciliary body, cornea, inner nuclear layer of the retina, and the optic nerve head. The recent finding that a common variant near EFEMP1 was associated with optic nerve-head morphology supports the possibility that the EFEMP1 variant identified in this POAG family may be pathogenic.

    Primary open-angle glaucoma (POAG) is an optic neuropathy that has a high worldwide prevalence and that shows strong evidence of complex inheritance. The myocilin (MYOC) gene is the only one that has thus far been shown to have mutations in patients with POAG. Apolipoprotein E (APOE) plays an essential role in lipid metabolism, and the APOE gene has been involved in neuronal degeneration that occurs in Alzheimer disease (AD). Here, we report that two APOE-promoter single-nucleotide polymorphisms (SNPs) previously associated with AD also modify the POAG phenotype. APOE(−219G) is associated with increased optic nerve damage, as reflected by increased cup:disk ratio and visual field alteration. In addition, APOE(−491T), interacting at a highly significant level with an SNP in the MYOC promoter, MYOC(−1000G), is associated with increased intraocular pressure (IOP) and with limited effectiveness of IOP-lowering treatments in patients with POAG. Together, these findings establish APOE as a potent modifier for POAG, which could explain the linkage to chromosome 19q previously observed by use of a genome scan for this condition and an increased frequency of glaucoma in patients with AD. The findings also shed new light on potential mechanisms of optic nerve damage and of IOP regulation in POAG. PMID:11992263

  7. Mapping of the disease locus and identification of ADAMTS10 as a candidate gene in a canine model of primary open angle glaucoma.

    Full Text Available Primary open angle glaucoma (POAG is a leading cause of blindness worldwide, with elevated intraocular pressure as an important risk factor. Increased resistance to outflow of aqueous humor through the trabecular meshwork causes elevated intraocular pressure, but the specific mechanisms are unknown. In this study, we used genome-wide SNP arrays to map the disease gene in a colony of Beagle dogs with inherited POAG to within a single 4 Mb locus on canine chromosome 20. The Beagle POAG locus is syntenic to a previously mapped human quantitative trait locus for intraocular pressure on human chromosome 19. Sequence capture and next-generation sequencing of the entire canine POAG locus revealed a total of 2,692 SNPs segregating with disease. Of the disease-segregating SNPs, 54 were within exons, 8 of which result in amino acid substitutions. The strongest candidate variant causes a glycine to arginine substitution in a highly conserved region of the metalloproteinase ADAMTS10. Western blotting revealed ADAMTS10 protein is preferentially expressed in the trabecular meshwork, supporting an effect of the variant specific to aqueous humor outflow. The Gly661Arg variant in ADAMTS10 found in the POAG Beagles suggests that altered processing of extracellular matrix and/or defects in microfibril structure or function may be involved in raising intraocular pressure, offering specific biochemical targets for future research and treatment strategies.

  8. Intensity-Modulated Radiotherapy as Primary Therapy for Prostate Cancer: Report on Acute Toxicity After Dose Escalation With Simultaneous Integrated Boost to Intraprostatic Lesion

    Purpose: To report on the acute toxicity of a third escalation level using intensity-modulated radiotherapy for prostate cancer (PCa) and the acute toxicity resulting from delivery of a simultaneous integrated boost (SIB) to an intraprostatic lesion (IPL) detected on magnetic resonance imaging (MRI), with or without spectroscopy. Methods and Materials: Between January 2002 and March 2007, we treated 230 patients with intensity-modulated radiotherapy to a third escalation level as primary therapy for prostate cancer. If an IPL (defined by MRI or MRI plus spectroscopy) was present, a SIB was delivered to the IPL. To report on acute toxicity, patients were seen weekly during treatment and 1 and 3 months after treatment. Toxicity was scored using the Radiation Therapy Oncology Group toxicity scale, supplemented by an in-house-developed scoring system. Results: The median dose to the planning target volume was 78 Gy. An IPL was found in 118 patients. The median dose to the MRI-detected IPL and MRI plus spectroscopy-detected IPL was 81 Gy and 82 Gy, respectively. No Grade 3 or 4 acute gastrointestinal toxicity developed. Grade 2 acute gastrointestinal toxicity was present in 26 patients (11%). Grade 3 genitourinary toxicity was present in 15 patients (7%), and 95 patients developed Grade 2 acute genitourinary toxicity (41%). No statistically significant increase was found in Grade 2-3 acute gastrointestinal or genitourinary toxicity after a SIB to an IPL. Conclusion: The results of our study have shown that treatment-induced acute toxicity remains low when intensity-modulated radiotherapy to 80 Gy as primary therapy for prostate cancer is used. In addition, a SIB to an IPL did not increase the severity or incidence of acute toxicity

    Full Text Available Objective: To retrospectively analyze the relationship of time of care, combined with possible post-appendectomy complications, with the promptness of transfer of patients seen in Emergency Care Units (UPA to the emergency hospital.Methods: We analyzed patients with preoperative diagnosis of acute appendicitis undergoing appendectomy from January to July 2012. Patients were divided into two groups according to the site of the first care. Group A included patients who received initial care directly in the emergency department of the Lourenço Jorge County Hospital (HMLJ and group B consisted of patients seen in the UPA and forwarded to HMLJ to undergo surgical treatment.Results: the average time between initial treatment and surgery in group A was 29 hours (SD = 21.95 and 54 hours in group B (SD = 54.5. Considering the onset of symptoms, the patients in group A were operated on average 67 hours after (SD = 42.55, while group B, 90 hours (SD = 59.58. After the operation, patients in group A were hospitalized, on average, for 94 hours (SD = 73.53 and group B, 129 hours (SD = 193.42.Conclusion: there was no significant difference in the time elapsed between the onset of symptoms, initial treatment and early surgical treatment, or time elapsed between surgery and discharge.
