2缺血性卒中患者的早期处理指南——美国卒中学会卒中委员会科学声明显示文摘1994年,美国心脏学会(AHA)卒中委员会委托一个专门研究小组撰写了急性缺血性卒中患者的处理指南[1].1996年,在静脉rtPA治疗急性缺血性卒中得到食品与药物管理局(FDA)批准后,这项指南又补充了一系列的推荐[2].曲东锋 陈兴洲 李宏建 倪长江 Harold P.Adams Jr Robert J.Adams Thomas Brott Gregory J.del Zoppo Anthony Furlan Larry B.Goldstein Robert L.Grubb Randall Higashida Chelsea Kidwell Thomas G.Kwiatkowski John R.Marler George J.Hadermenos 2003国外医学(脑血管疾病分册)2003,11,5:57
3帕博利珠单抗单用或与放疗联用治疗转移性非小细胞肺癌:两个随机试验的汇总分析显示文摘背景放疗可以提高整个机体对免疫治疗的应答。在Ⅱ期PEMBRO-RT研究和Ⅰ/Ⅱ期MDACC研究中,患有转移性非小细胞肺癌(NSCLC)的患者被随机分配入组,接受免疫治疗(帕博利珠单抗)+放疗联合疗法,或免疫治疗单一疗法。当上述2个研究单独分析时,联合疗法组显示出潜在获益。由于每个研究的样本量较小,缓解率和结局并未显示出统计学意义,然而却有显著的临床获益。因此,本研究进行汇总分析,来判断放疗是否会改善转移性NSCLC患者的免疫治疗应答。方法PEMBRO-RT和MDACC研究纳入标准:患者年龄≥18岁,患有转移性NSCLC,且有≥1处未经放疗照射的病灶,以便进行射野外应答监测。PEMBRO-RT研究纳入曾接受过化疗患者,MDACC研究纳入曾接受过治疗或新诊断患者。2个研究中的患者均未接受过免疫治疗。在PEMBRO-RT研究中患者被等比例随机分配入组,并根据吸烟状态进行分层(分为<10年组和≥10年组)。MDACC研究的患者根据放疗计划可行性被等比例随机分配入2个受试组。由于联合治疗组的干预本质,每个研究中的放疗均不适用盲法。在2个研究中,不论是否进行放疗,均静脉滴入帕博利珠单抗(每3周200 mg)。在PEMBRO-RT研究中,在放疗(24 Gy 3次分割照射)结束后1周给予第1剂帕博利珠单抗。在MDACC研究中,在第1次放疗(50 Gy 4次分割照射或45 Gy 15次分割照射)同时给予帕博利珠单抗。仅检测未经照射病灶的应答。本研究的终点为最佳射野外(远隔)应答率(ARR)、最佳射野外疾病控制率(ACR)、12周时ARR、12周时ACR、无进展生存期(PFS)和总生存期(OS)。2个研究的意向治疗(ITT)人群均纳入分析。PEMBRO-RT研究(NCT02492568)和MDACC研究(NCT02444741)均在ClinicalTrials.gov上注册。发现纳入148例患者,76例接受帕博利珠单抗治疗,72例接受帕博利珠单抗+放疗治疗。所有患者随访时间中位数为33个月[四分位距(IQR):32.4~33.6]。148例患者中124例(84%)组织学特征为非鳞癌,111例(75%)患者曾经接受过化疗。组间没有基线特征差异,包括PD-L1表达状态和转移灶体积。最常见的照射部位为肺转移灶(39%,28/72)、胸腔内淋巴结(21%,15/72)和非原发灶(17%,12/72)。帕博利珠单抗组和联合治疗组的最佳ARR分别为19.7%(15/76)和41.7%(30/72),OR=2.96,95%CI:1.42~6.20,P=0.0039;最佳ACR分别为43.4%(33/76)和65.3%(47/72),OR=2.51,95%CI:1.28~4.91,P=0.0071;PFS中位数分别为4.4(IQR:2.9~5.9)和9.0个月(IQR:6.8~11.2),HR=0.67,95%CI:0.45~0.99,P=0.045;OS中位数分别为8.7(IQR:6.4~11.0)和19.2个月(IQR:14.6~23.8),OR=0.67,95%CI:0.54~0.84,P=0.0004。在汇总分析中没有发现新的安全问题。解读帕博利珠单抗免疫疗法+放疗显著提高转移性NSCLC患者的应答和改善治疗结局。这些结果需要在三期临床试验中进行验证。陈大卫(翻译) 于金明(校对) Willemijn S M E Theelen Vivek Verma Brian P Hobbs Heike M U Peulen Joachim G J V Aerts Idris Bahce Anna Larissa N Niemeijer Joe Y Chang Patricia M de Groot Quynh-Nhu Nguyen Nathan I Comeaux George R Simon Ferdinandos Skoulidis Steven H Lin Kewen He Roshal Patel John Heymach Paul Baas James W Welsh 2021中华肿瘤防治杂志2021,28,24:49

5Pancreatic insulinoma:current issues and trends显示文摘BACKGROUND:Although insulinomas are very rare tumors, they are the most common pancreatic neuroendocrine neoplasms.The incidence in general population is 1-4 per 1 000 000 yearly but the incidence is higher in autopsy studies. The malignancy of insulinomas is difficult to be predicted on the basis of their histological features,and the current WHO classification has been re-evaluated.This review aimed to summarize classical knowledge with current trends in the diagnosis and treatment of insulinomas. DATA SOURCES:A Medline search using terms'insulinoma', 'treatment'and'neuroendocrine tumors'was conducted. Additional references were sourced from key articles. RESULTS:Surgery is the treatment of choice for insulinoma and has an extremely high success rate.Medical treatment is also available but only for patients who are unable or unwilling to undergo surgical treatment.Preoperative localization is necessary for planning the surgical approach.Many methods exist for localization of an insulinoma and can be invasive and non-invasive.The combination of biphasic thin section helical CT and endoscopic ultrasonography(EUS)has an almost 100% sensitivity in localizing insulinomas.Laparoscopic ultrasound is mandatory to localize intraoperatively these tumors.EUS-guided fine needle tattoing is an alternative method of localization in case of lack of laparoscopic ultrasound. CONCLUSION:Laparoscopic resection for benign insulinomas is the procedure of choice,whereas pancreatectomy is reserved for large,potentially malignant tumors.Dennis Vaidakis John Karoubalis Theodora Pappa George Piaditis George N Zografos 2010Hepatobiliary & Pancreatic Diseases International2010,9,3:22
6Pneumobilia,chronic diarrhea,vitamin K malabsorption:A pathognomonic triad for cholecystocolonic fistulas显示文摘Cholecystocolonic fistula (CF) is an uncommon type of internal biliary-enteric fistulas, which comprise rare complications of cholelithiasis and acute cholecystitis, with a prevalence of about 2% of all biliary tree diseases. We report a case of a spontaneous CF in a 75-year-old diabetic male admitted to hospital for the investigation of chronic watery diarrhea and weight loss. Massive pneumobilia demonstrated on abdominal ultrasound and computerized tomography, along with chronic, bile acid-induced diarrhea and a prolonged prothrombin time due to vitamin K malabsorption, led to the clinical suspicion of the fistula. Despite further investigation with barium enema and magnetic resonance cholangio-pancreatography, diagnosis of the fistulous tract between the gallbladder and the hepatic flexure of the colon could not be established preoperatively. Open cholecystectomy with fistula resection and exploration of the common bile duct was the preferred treatment of choice, resulting in an excellent postoperative clinical course. The incidence of biliary-enteric fistulas is expected to increase due to the parallel increase of iatrogenic interventions to the biliary tree with the use of endoscopic retrograde cholangio-pancreatography and the increased rate of cholecystectomies performed. Taking into account that advanced imaging techniques fail to demonstrate the fistulas tract in half of the cases, and that CFs usually present with non-specific symptoms, our report could assist physicians to keep a high index of clinical suspicion for an early and valid diagnosis of a CF.Savvoula Savvidou John Goulis Alexandra Gantzarou George Ilonidis 2009World Journal of Gastroenterology2009,15,32:20
7Role of radiotherapy in the management of hepatocellular carcinoma:A systematic review显示文摘Many patients with hepatocellular carcinoma(HCC) present with advanced disease,not amenable to curative therapies such as surgery,transplantation or radiofrequency ablation. Treatment options for this group of patients include transarterial chemoembolization(TACE) and radiation therapy. Especially TACE,delivering a highly concentrated dose of chemotherapy to tumor cells while minimizing systemic toxicity of chemotherapy,has given favorable results on local control and survival. Radiotherapy,as a therapeutic modality of internal radiation therapy with radioisotopes,has also achieved efficacious tumor control in advanced disease. On the contrary,the role of external beam radiotherapy for HCC has been limited in the past,due to the low tolerance of surrounding normal liver parenchyma. However,technological innovations in the field of radiotherapy treatment planning and delivery,have provided the means of delivering radical doses to the tumor,while sparing normal tissues. Advanced and highly conformal radiotherapy approaches such as stereotactic body radiotherapy and proton therapy,evaluated for efficacy and safety for HCC,report encouraging results. In this review,we present the role of radiotherapy in hepatocellular carcinoma patients not suitable for radical treatment.Maria-Aggeliki Kalogeridi Anna Zygogianni George Kyrgias John Kouvaris Sofia Chatziioannou Nikolaos Kelekis Vassilis Kouloulias 2015World Journal of Hepatology2015,7,1:18
8Differential regulation of JAK/STAT-signaling in patients with ulcerative colitis and Crohn’s disease显示文摘In 2018,the pan-Janus kinase(JAK)inhibitor tofacitinib was launched for the treatment of ulcerative colitis(UC).Although tofacitinib has proven efficacious in patients with active UC,it failed in patients with Crohn’s disease(CD).This finding strongly hints at a different contribution of JAK signaling in both entities.Here,we review the current knowledge on the interplay between the JAK/signal transducer and activator of transcription(STAT)pathway and inflammatory bowel diseases(IBD).In particular,we provide a detailed overview of the differences and similarities of JAK/STAT-signaling in UC and CD,highlight the impact of the JAK/STAT pathway in experimental colitis models and summarize the published evidence on JAK/STAT-signaling in immune cells of IBD as well as the genetic association between the JAK/STAT pathway and IBD.Finally,we describe novel treatment strategies targeting JAK/STAT inhibition in UC and CD and comment on the limitations and challenges of the new drug class.Friederike Cordes Dirk Foell John Nik Ding Georg Varga Dominik Bettenworth 2020World Journal of Gastroenterology2020,26,28:16

11Red blood cell distribution width in elderly hospitalized patients with cardiovascular disease显示文摘BACKGROUND Red blood cell distribution width(RDW)is elevated in patients with cardiovascular disease(CVD).AIM To determine RDW values and impact of CV and non-CV coexisting morbidities in elderly patients hospitalized with chronic CVD.METHODS This prospective study included 204 consecutive elderly patients(age 77.5[7.41]years,female 94[46%],left ventricular ejection fraction 53.00%[37.50,55.00])hospitalized with chronic CVD at the Cardiology Department of Larissa University General Hospital(Larissa,Greece)from January 2019 to April 2019.Elderly patients were selected due to the high prevalence of coexisting morbidities in this patient population.Hospitalized patients with acute CVD(acute coronary syndromes,new-onset heart failure[HF],and acute pericarditis/myocarditis),primary isolated valvular heart disease,sepsis,and those with a history of blood transfusions or cancer were excluded.The evaluation of the patients within 24 h from admission included clinical examination,laboratory blood tests,and echocardiography.RESULTS The most common cardiac morbidities were hypertension and coronary artery disease,with acutely decompensated chronic heart failure(ADCHF)and atrial fibrillation(AF)also frequently being present.The most common non-cardiac morbidities were anemia and chronic kidney disease followed by diabetes mellitus,chronic obstructive pulmonary disease,and sleep apnea.RDW was significantly elevated 15.48(2.15);121(59.3%)of patients had RDW>14.5%which represents the upper limit of normal in our institution.Factors associated with RDW in stepwise regression analysis were ADCHF(coefficient:1.406;95%confidence interval[CI]:0.830-1.981;P<0.001),AF(1.192;0.673 to 1.711;P<0.001),and anemia(0.806;0.256 to 1.355;P=0.004).ADCHF was the most significant factor associated with RDW.RDW was on average 1.41 higher for patients with than without ADCHF,1.19 higher for patients with than without AF,and 0.81 higher for patients with than without anemia.When patients were grouped based on the presence or absence of anemia,ADCHF and AF,heart rate was not increased in those with anemia but was significantly increased in those with ADCHF or AF.CONCLUSION RDW was elevated in elderly hospitalized patients with chronic CVD.Factors associated with RDW were anemia and CV factors associated with elevated heart rate(ADCHF,AF),suggesting sympathetic overactivity.Andrew Xanthopoulos Konstantinos Tryposkiadis Apostolos Dimos Angeliki Bourazana Alexandros Zagouras Nikolaos Iakovis Michail Papamichalis Grigorios Giamouzis George Vassilopoulos John Skoularigis Filippos Triposkiadis 2021World Journal of Cardiology2021,13,9:13
12Severe scrub typhus infection: Clinical features, diagnostic challenges and management显示文摘Scrub typhus infection is an important cause of acute undifferentiated fever in South East Asia. The clinical picture is characterized by sudden onset fever with chills and non-specific symptoms that include headache, myalgia, sweating and vomiting. The presence of an eschar, in about half the patients with proven scrub typhus infection and usually seen in the axilla, groin or inguinal region, is characteristic of scrub typhus. Common laboratory findings are elevated liver transaminases, thrombocytopenia and leukocytosis. About a third of patients admitted to hospital with scrub typhus infection have evidence of organ dysfunction that may include respiratory failure, circulatory shock, mild renal or hepatic dysfunction, central nervous system involvement or hematological abnormalities. Since the symptoms and signs are non-specific and resemble other tropical infections like malaria, enteric fever, dengue or leptospirosis, appropriate laboratory tests are necessary to confirm diagnosis. Serological assays are the mainstay of diagnosis as they are easy to perform; the reference test is the indirect immunofluorescence assay(IFA) for the detection of Ig M antibodies. However in clinical practice, the enzyme-linked immuno-sorbent assay is done due to the ease of performing this test and a good sensitivity and sensitivity when compared with the IFA. Paired samples, obtained at least two weeks apart, demonstrating a ≥ 4 fold rise in titre, is necessary for confirmation of serologic diagnosis. The mainstay of treatment is the tetracycline group of antibiotics or chloramphenicol although macrolides are used alternatively. In mild cases, recovery is complete. In severe cases with multi-organ failure, mortality may be as high as 24%.John Victor Peter Thomas I Sudarsan John Anthony J Prakash George M Varghese 2015World Journal of Critical Care Medicine2015,4,3:13

14Hepatocellular carcinoma in chronic hepatitis B patients under antiviral therapy显示文摘Patients with chronic hepatitis B are at increased risk of hepatocellular carcinoma(HCC),while the inhibition of viral replication can represent a reasonable target for HCC prevention.Interferon-αtherapy results in decreased HCC risk,which is more evident in patients with high baseline HCC risk.The majority of chronic hepatitis B patients are treated with a nucleos(t)ide analogue(NA)for several reasons including the nonsustained response after interferon-α.The effect of the first licensed and low genetic barrier NA,lamivudine,on HCC incidence,has been repeatedly evaluated.Lamivudine,compared to no treatment,reduces the HCC incidence,which may increase again in cases with lamivudine resistance.Emerging data with the currently first-line NAs,entecavir and tenofovir,suggest that they also reduce the HCC incidence.The treatment benefit in reduction of the HCC incidence is always greater in patients with high baseline HCC risk,particularly cirrhotics,and without virological remission under entecavir/tenofovir.However,the HCC risk is not eliminated even in the vast majority of patients who remain in virological remission under entecavir/tenofovir.Therefore,patients at increased baseline HCC risk should continue to undergo HCC surveillance even if they have achieved complete long-term inhibition of viral replication and improvements in liver histology.John Vlachogiannakos George Papatheodoridis 2013World Journal of Gastroenterology2013,19,47:9
15Alterations in the function of circulating mononuclear cells derived from patients with Crohn’s disease treated with mastic显示文摘AIM: To assess the effects of mastic administration on cytokine production of circulating mononuclear cells of patients with active Crohn's disease (CD). METHODS: The study was conducted in patients with established mildly to moderately active CD, attending the outpatient clinics of the hospital, and in healthy controls. Recruited to a 4 wk treatment with mastic caps (6 caps/d, 0.37 g/cap) were 10 patients and 8 controls, all of who successfully completed the protocol. Interleukin-6 (IL-6), tumor necrosis factor-alpha (TNF-α), monocyte chemotactic protein-1 (MCP-1), macrophage migration inhibitory factor (MIF) and intracellular antioxidant glutathione (GSH) were evaluated in peripheral blood mononuclear cells (PBMC) before and after treatment. RESULTS: Treating CD patients with mastic resulted in the reduction of TNF-α secretion (2.1 ± 0.9 ng/mL vs 0.5 ± 0.4 ng/mL, P = 0.028). MIF release was signif icantly increased (1.2 ± 0.4 ng/mL vs 2.5 ± 0.7 ng/mL, P = 0.026) meaning that random migration and chemotaxis of monocytes/macrophages was inhibited. No signifi cant changes were observed in IL-6, MCP-1 and GSH concentrations. CONCLUSION: This study shows that mastic acts as an immunomodulator on PBMC, acting as a TNF-α inhibitor and a MIF stimulator. Although further double-blind, placebo-controlled studies in a large number of patients is required to clarify the role of this natural product, this f inding provides strong evidence that mastic might be an important regulator of immunity in CD.Andriana C Kaliora Maria G Stathopoulou John K Triantaf illidis George VZ Dedoussis Nikolaos K Andrikopoulos 2007World Journal of Gastroenterology2007,13,45:8
16Treatment of hemorrhoids: A survey of surgical practice in Australia and New Zealand显示文摘BACKGROUND Hemorrhoidal disease is the most common anorectal disorder.Hemorrhoids can be classified as external or internal,according to their relation to the dentate line.External hemorrhoids originate below the dentate line and are managed conservatively unless the patient cannot keep the perianal region clean,or they cause significant discomfort.Internal hemorrhoids originate above the dentate line and can be managed according to the graded degree of prolapse,as described by Goligher.Generally,low-grade internal hemorrhoids are effectively treated conservatively,by non-operative measures,while high-grade internal hemorrhoids warrant procedural intervention.AIM To determine the application of clinical practice guidelines for the current management of hemorrhoids and colorectal surgeon consensus in Australia and New Zealand.METHODS An online survey was distributed to 206 colorectal surgeons in Australia and New Zealand using 17 guideline-based hypothetical clinical scenarios.RESULTS There were 82 respondents(40%)to 17 guideline-based scenarios.Nine(53%)reached consensus,of which only 1(6%)disagreed with the guidelines.This was based on low quality evidence for the management of acutely thrombosed external hemorrhoids.There were 8 scenarios which showed community equipoise(47%)and they were equally divided for agreeing or disagreeing with the guidelines.These topics were based on low and moderate levels of evidence.They included the initial management of grade I internal hemorrhoids,grade III internal hemorrhoids when initial management had failed and the patient had recognised risks factors for septic complications;and finally,the decision-making when considering patient preferences,including a prompt return to work,or minimal post-operative pain.CONCLUSION Although there are areas of consensus in the management of hemorrhoids,there are many areas of community equipoise which would benefit from further research.George E Fowler Javariah Siddiqui Assad Zahid Christopher John Young 2019World Journal of Clinical Cases2019,7,22:8

18Chios mastic treatment of patients with active Crohn's disease显示文摘AIM: To evaluate the effectiveness of mastic administra-tion on the clinical course and plasma inflammatory me-diators of patients with active Crohn’s disease (CD).METHODS: This pilot study was conducted in patients with established mild to moderately active CD, attend-ing the outpatient clinics of the hospital, and in healthy controls. Ten patients and 8 controls were recruited for a 4-wk treatment with mastic caps (6 caps/d, 0.37 g/cap). All patients successfully completed the protocol. CD Ac-tivity Index (CDAI), Nutritional Risk Index (NRI), C-re-active protein (CRP), interleukin-6 (IL-6), tumor necrosis factor-alpha (TNF-α), monocyte chemotactic protein-1 (MCP-1), and total antioxidant potential (TAP) were evaluated in the plasma at baseline and at the end of the treatment period. Results were expressed as mean values ± SE and P < 0.05 was considered to indicate statistical significance.RESULTS: Patients exhibited significant reduction of CDAI (222.9 ± 18.7 vs 136.3 ± 12.3, P = 0.05) as com-pared to pretreament values. Plasma IL-6 was signifi-cantly decreased (21.2 ± 9.3 pg/mL vs 7.2 ± 2.8 pg/ mL, P = 0.027), and so did CRP (40.3 ± 13.1 mg/mL vs 19.7 ± 5.5, P = 0.028). TAP was significantly increased (0.15 ± 0.09 vs 0.57 ± 0.15 mmol/L uric acid, P = 0.036). No patient or control exhibited any kind of side effects. CONCLUSION: The results suggest that mastic signifi-cantly decreased the activity index and the plasma levels of IL-6 and CRP in patients with mildly to moderately ac-tive CD. Further double-blind, placebo-controlled studies in a larger number of patients are required to clarify the role of this natural product in the treatment of patients with CD.Andriana C Kaliora Maria G Stathopoulou John K Triantafillidis George VZ Dedoussis Nikolaos K Andrikopoulos 2007World Journal of Gastroenterology2007,13,5:7
19顶空固相微萃取法(SPME)检测小麦受害虫感染情况初步研究显示文摘研究了一种新的用于检测储藏小麦害虫感染的方法——顶空固相微萃取法(SPME),实验结果表明:利用SPME法所提取的几种常见储粮害虫(谷蠹Rhyzopertha dominica、赤拟谷盗Tribolium castaneum、扁谷盗Cryptolestes ferrugineus与锈赤扁谷盗Cryptolestes pusillus)所释放的挥发性信息素可以作为粮食受害虫感染的检测指标,同时由于它们所释放的信息素量不同(谷蠹最高,其次分别是赤拟谷盗﹑扁谷盗和锈赤扁谷盗),这也直接导致了SPME法检测灵敏度的不同,实验结果表明:在1kg的储藏小麦中能够成功地检测出1头赤拟谷盗和1头谷蠹,而扁谷盗和锈赤扁谷盗则需要更多的数量才能够被检测出来。此外,提取时间与温度也会影响SPME的灵敏度,实验证明:较长的提取时间与较高的实验温度都会增加信息素的产量,通过多次验证最终认定最佳提取条件为:温度50℃,时间4h。总之,将SPME法应用到粮食仓储行业中用于检测粮食受害虫感染的程度虽已初见成果,但还需要进一步地深入研究,使用动态顶空进样法或许可以提高SPME技术的灵敏性。Wathukan Laopongist George Srzednicki John Craske 方茜 2014粮食储藏2014,43,6:7
20Standard manual capsulorhexis / Ultrasound phacoemulsification compared to femtosecond laser-assisted capsulorhexis and lens fragmentation in clear cornea small incision cataract surgery显示文摘Background:Femtosecond-laser assisted clear cornea cataract surgery may hold promise in safer and more effective procedures.We decided to perform a comparative study to standard manual incision phacoemulsification surgery.Methods:This is a single-center,single-intervention,and prospective comparative data evaluation of 133 consecutive cases subjected to cataract surgery.Group-A(Phaco),manual capsulorhexis&ultrasound phacoemulsification(n=66);Group-B femtosecond-laser assisted capsulorhexis and lens fragmentation(n=67),employing the LenSx laser(Alcon Surgical,Ft.Worth,TX).All cases were evaluated for refraction,visual acuity,keratometry,tomography,pachymetry,endothelial cell counts,intraocular pressure,and type of intraocular lens(IOL)implanted.The groups were matched for age,gender,pre-operative vision metrics,and cataract grade,and were followed up to 1 year.Results:In group-A post-operative uncorrected distance visual acuity(UDVA)was 20/20 or better in 61.5%and 20/25 or better in 78.5%of the eyes.The femtosecond laser group-B had improved outcomes(p=0.075 and p=0.042,respectively):post-operative UDVA was 20/20 or better in 62.7%of the eyes and 20/25 or better in 85.1%.Linear regression scatterplots of achieved versus attempted spherical equivalent had excellent regression coefficients(r^(2)=0.983 in group-A and 0.979 in group-B).There were 75.2%cases in group-A and 80.6%in group-B(p=0.8732)within±0.50 D of targeted refractive equivalent.Slight trend of under-correction was noted in group-A.Average residual manifest cylinder in the toric subgroup-A was-0.50 D(95%Limit-of-Agreement(LoA)=-0.78 D),and in toric subgroup-B-0.45 D(LoA=-0.45 D).Conclusions:Mean spherical equivalent refraction and visual acuity are comparable with laser cataract surgery compared with manual capsulorhexis&ultrasound phacoemulsification.Improved astigmatism correction may be among the benefits of femtosecond laser–assisted cataract surgery.Transient corneal edema may be a first day transient disadvantage in femtosecond laser–assisted cataract surgery.Anastasios John Kanellopoulos George Asimellis 2016Eye and Vision2016,3,1:7
