| 1 | Combination of propofol and dezocine to improve safety and efficacy of anesthesia for gastroscopy and colonoscopy in adults: A randomized, double-blind, controlled trial显示文摘BACKGROUND Gastroscopy and colonoscopy are important and common endoscopic methods for the diagnosis and treatment of gastrointestinal and colorectal diseases.However,endoscopy is usually associated with adverse reactions such as nervousness,nausea,vomiting,choking cough,and pain.Severe discomfort,such as vomiting,coughing,or body movement,may lead to aggravation of a preexisting condition or even interruption of examination or treatment,especially in some critically ill patients with physiological dysfunction(e.g.,cardiovascular or respiratory disease).The optimal methods for inducing analgesia and sedation in endoscopy are areas of ongoing debate;nevertheless,determining an appropriate regimen of sedation and analgesia is important.AIM To evaluate the effects of propofol combined with dezocine,sufentanil,or fentanyl in painless gastroscopy and colonoscopy.METHODS Four hundred patients were randomly assigned to one of four groups for anesthesia:intravenous dezocine,sufentanil,fentanyl,or saline.Propofol was administered intravenously for induction and maintenance of anesthesia.RESULTS The dosage of propofol in the dezocine group was significantly lower than those in other groups(P<0.01).Bispectral index and Steward score(0-6 points,an unresponsive,immobile patient whose airway requires maintenance to a fully recovered patient)after eye opening in the dezocine group were significantly higher than those in other groups(P<0.01).Awakening time and postoperative pain score(0-10 points,no pain to unbearable pain)in the dezocine group were significantly lower than those in other groups(P<0.01).Mean arterial pressure and pulse oxygen saturation in the dezocine group were significantly more stable at various time points(before dosing,disappearance of eyelash reflex,and wakeup)than those in other groups(P<0.01).The rates of hypopnea,jaw thrust,body movements,and usage of vasoactive drugs in the dezocine group were significantly lower than those in other groups(P<0.01).Additionally,the rates of reflex coughing,nausea,and vomiting were not statistically different between the four groups(P>0.05).CONCLUSION The combination of propofol and dezocine can decrease propofol dosage,reduce the risk for the development of inhibitory effects on the respiratory and cardiovascular systems,increase analgesic effect,decrease body movement,shorten awakening time,and improve awakening quality. | Xue-Ting Li Chao-Qun Ma Si-Hua Qi Li-Min Zhang | 2019 | World Journal of Clinical Cases2019，7，20： | 61 |
| 2 | Antimicrobial resistance in Acinetobacter baumannii : From bench to bedside显示文摘Acinetobacter baumannii(A. baumannii) is undoubtedly one of the most successful pathogens in the modern healthcare system. With invasive procedures, antibiotic use and immunocompromised hosts increasing in recent years, A. baumannii has become endemic in hospitals due to its versatile genetic machinery, which allows it to quickly evolve resistance factors, and to its remarkable ability to tolerate harsh environments. Infections and outbreaks caused by multidrugresistant A. baumannii(MDRAB) are prevalent and have been reported worldwide over the past twenty or more years. To address this problem effectively, knowledge of species identification, typing methods, clinical manifestations, risk factors, and virulence factors is essential. The global epidemiology of MDRAB is monitored by persistent surveillance programs. Because few effective antibiotics are available, clinicians often face serious challenges when treating patients with MDRAB. Therefore, a deep understanding of the resistance mechanisms used by MDRAB can shed light on two possible strategies to combat the dissemination of antimicrobial resistance: stringent infection control and antibiotic treatments, of which colistin-based combination therapy is the mainstream strategy. However, due to the current unsatisfying therapeutic outcomes, there is a great need to develop and evaluate the efficacy of new antibiotics and to understand the role of other potential alternatives, such as antimicrobial peptides, in the treatment of MDRAB infections. | Ming-Feng Lin Chung-Yu Lan | 2014 | World Journal of Clinical Cases2014，2，12： | 55 |
| 3 | Aetiology of idiopathic granulomatous mastitis显示文摘Idiopathic granulomatous mastitis is a rare chronic inflammatory lesion of the breast that can clinically and radiographically mimic breast carcinoma. The most common clinical presentation is an unilateral, discrete breast mass, nipple retraction and even a sinus formation often associated with an inflammation of the overlying skin. The etiology of idiopathic granulomatous mastitis is still obscure. Its treatment remains controversial. The cause may be the autoimmune process, infection, a chemical reaction associated with oral contraceptive pills, or even lactation. Various factors, including hormonal imbalance, autoimmunity, unknown microbiological agents, smoking and α 1-antitrypsin deficiency have been suggested to play a role in disease aetiology. In this review, causing factors in the aetiology of idiopathic granulomatous mastitis are reviewed in detail. | Fatih Altintoprak Taner Kivilcim Orhan Veli Ozkan | 2014 | World Journal of Clinical Cases2014，2，12： | 52 |
| 4 | Different strategies of treatment for uterine cervical carcinoma stage ⅠB2-ⅡB显示文摘Uterine cervical cancer is the second most common gynecological malignancy. It is estimated that over 35% of tumors are diagnosed at locally advanced disease, stage ⅠB2-ⅡB with an estimated 5-year overall survival of 60%. During the last decades, the initial treatment for these women has been debated and largely varies through different countries. Thus, radical concurrent chemoradiation is the standard of care in United Sated and Canada, and neoadjuvant chemotherapy followed by radical surgery is the first line of treatment in some institutions of Europe, Asia and Latin America. Until today, there is no evidence of which strategy is better over the other. This article describe the evidence as well as the advantages and disadvantages of the main strategies of treatment for women affected by uterine cervical cancer stage ⅠB2-ⅡB. | Lucas Minig María Guadalupe Patrono Nuria Romero Juan Francisco Rodríguez Moreno Jesús Garcia-Donas | 2014 | World Journal of Clinical Oncology2014，5，2： | 46 |
| 5 | Clinical application of DNA ploidy to cervical cancer screening: A review显示文摘Screening for cervical cancer with DNA ploidy assessment by automated quantitative image cytometry has spread throughout China over the past decade and now an estimated 1 million tests per year are done there. Compared to conventional liquid based cytology, DNA ploidy has competitive accuracy with much higher throughput per technician. DNA ploidy has the enormous advantage that it is an objective technology that can be taught in typically 2 or 3 wk, unlike qualitative cytology, and so it can enable screening in places that lack sufficient qualified cytotechnologists and cytopathologists for conventional cytology. Most papers on experience with application of the technology to cervical cancer screening over the past decade were published in the Chinese language. This review aims to provide a consistent framework for analysis of screening data and to summarize some of the work published from 2005 to the end of 2013. Of particular interest are a few studies comparing DNA ploidy with testing for high risk human papilloma virus(hrH PV) which suggest that DNA ploidy is at least equivalent, easier and less expensive than hrH PV testing. There may also be patient management benefits to combining hr HPV testing with DNA ploidy. Some knowledge gaps are identified and some suggestions are made for future research directions. | David Garner | 2014 | World Journal of Clinical Oncology2014，5，5： | 43 |
| 6 | Omicron variant (B.1.1.529) of SARS-CoV-2: Mutation, infectivity, transmission, and vaccine resistance显示文摘The appearance of severe acute respiratory syndrome coronavirus 2(SARS-CoV-2)variant Omicron(B.1.1.529)has caused panic responses around the world because of its high transmission rate and number of mutations.This review summarizes the highly mutated regions,the essential infectivity,transmission,vaccine breakthrough and antibody resistance of the Omicron variant of SARSCoV-2.The Omicron is highly transmissible and is spreading faster than any previous variant,but may cause less severe symptoms than previous variants.The Omicron is able to escape the immune system’s defenses and coronavirus disease 2019 vaccines are less effective against the Omicron variant.Early careful preventive steps including vaccination will always be key for the suppression of the Omicron variant. | Shi-Yan Ren Wen-Biao Wang Rong-Ding Gao Ai-Mei Zhou | 2022 | World Journal of Clinical Cases2022，10，1： | 44 |

During the past twenty years, several case-control studies revealed the high risk factors of CRC in China, which were personal history of intestinal polyp,chronic diarrhea, feces with mucin and blood, psychic attack, drinking of unclear water, operation on appendix, history of chronic constipation and family history of cancer. From these factors, a risk-asessment mode (AD value) was constructed, combined with RPHA-FOB, a mass screening mode was established and applied into common people, awarded with a good result. The populationbased CRC prevention including randomized trial has been conducted in two fields( Haining city and Jiashan city in Zhejiang province), which demonstrated that removal of CRC pre-cancer lesions such as adenomas and polyps could reduce CRC incidence and mortalitv remarkablv. | ZHENGShu CAIShanrong | 2003 | The Chinese-German Journal of Clinical Oncology2003，2，2： | 45 |
| 8 | The Inhibitory Effect of Oridonin on the Growth of Fifteen Human Cancer Cell Lines显示文摘OBJECTIVE To study the inhibitory effect of oridonin on the growth of cancer cells. METHODS Fifteen human cancer cell lines were subjected to various concentrations of oridonin in culture medium. The inhibitory rate of cell growth was measured by the MTT assay, and compared with a negative con- trol and 5-Fu-positive control. RESULTS The 50% inhibiting concentration (IC50) and maximal inhibition (Imax) of oridonin shown by studying the growth of the cancer cell lines were as follows: leukemias (HL60 cells: 3.9 μg/ml and 73.8%, K562 cells: 4.3 μg/ml and 76.2%); esophageal cancers(SHEEC cells: 15.4 μg/ml and 99.2%, Eca109 cells: 15.1 μg/ml and 84.6%, TE1 cells: 4.0 μg/ml and 70.2%); gastric cancers (BGC823 cells: 7.6 μg/ml and 98.7%, SGC7901 cells: 12.3 μg/ml and 85.7%); colon cancers (HT29 cells: 13.6 μg/ml and 97.2%, HCT cells: 14.5 μg/ml and 96.5%); liver cancers (Bel7402 cells: 15.2 μg/ml and 89.2%, HepG2 cells: 7.1 μg/ml and 88.3%); pancreatic cancer (PC3 cells: 11.3 μg/ml and 68.4%); lung cancer (A549 cells: 18.6 μg/ml and 98.0% ); breast cancer (MCF7 cells: 18.4 μg/ml and 84.7%); uterine cervix cancer (Hela cells: 13.7 μg/ml and 98.5%). CONCLUSION Oridonin had a relatively wide anti-tumor spectrum, and a relatively strong inhibitory effect on the growth of the 15 human cancer cells. Inhibitory effects were concentration dependent. | Junhui Chen Shaobin Wang Dongyang Chen Guisheng Chang Qingfeng Xin Shoujun Yuan Zhongying Shen | 2007 | Chinese Journal of Clinical Oncology2007，4，1： | 32 |
| 9 | Therapeutic management options for stage Ⅲ non-small cell lung cancer显示文摘Lung cancer is the leading cause of cancer death worldwide.Majority of newly diagnosed lung cancers are non-small cell lung cancer(NSCLC), of which up to half are considered locally advanced at the time of diagnosis.Patients with locally advanced stage Ⅲ NSCLC consists of a heterogeneous population, making management for these patients complex.Surgery has long been the preferred local treatment for patients with resectable disease.For select patients, multimodality therapy involving systemic and radiation therapies in addition to surgery improves treatment outcomes compared to surgery alone.For patients with unresectable disease, concurrent chemoradiation is the preferred treatment.More recently, research into different chemotherapy agents, targeted therapies, radiation fractionation schedules, intensity-modulated radiotherapy, and proton therapy have shown promise to improve treatment outcomes and quality of life.The array of treatment approaches for locally advanced NSCLC is large and constantly evolving.An updated review of past and current literature for the roles of surgery, chemotherapeutic agents, radiation therapy, and targeted therapy for stage Ⅲ NSCLC patients are presented. | Stephanie M Yoon Talha Shaikh Mark Hallman | 2017 | World Journal of Clinical Oncology2017，8，1： | 32 |
| 10 | High intensity focused ultrasound in clinical tumor ablation显示文摘Recent advances in high intensity focused ultrasound(HIFU),which was developed in the 1940s as a viable thermal tissue ablation approach,have increased its popularity.In clinics,HIFU has been applied to treat a variety of solid malignant tumors in a well-defined volume,including the pancreas,liver,prostate,breast,uterine fibroids,and soft-tissue sarcomas.In comparison to conventional tumor/cancer treatment modalities,such as open surgery,radio-and chemo-therapy,HIFU has the advantages of non-invasion,non-ionization,and fewer complications after treatment.Over 100 000 cases have been treated throughout the world with great success.The fundamental principles of HIFU ablation are coagulative thermal necrosis due to the absorption of ultrasound energy during transmission in tissue and the induced cavitation damage.This paper reviews the clinical outcomes of HIFU ablation for applicable cancers,and then summarizes the recommendations for a satisfactory HIFU treatment according to clinical experience.In addition,the current challenges in HIFU for engineers and physicians are also included.More recent horizons have broadened the application of HIFU in tumor treatment,such as HIFU-mediated drug delivery,vessel occlusion,and soft tissue erosion(“histotripsy”).In summary,HIFU is likely to play a significant role in the future oncology practice. | Yu-Feng Zhou | 2011 | World Journal of Clinical Oncology2011，2，1： | 33 |
| 11 | Cardiovascular risk factors for acute stroke: Risk profiles in the different subtypes of ischemic stroke显示文摘Timely diagnosis and control of cardiovascular risk factors is a priority objective for adequate primary and secondary prevention of acute stroke. Hypertension, atrial fibrillation and diabetes mellitus are the most common risk factors for acute cerebrovascular events, although novel risk factors, such as sleep-disordered breathing, inflammatory markers or carotid intima-media thickness have been identified. However, the cardiovascular risk factors profile differs according to the different subtypes of ischemic stroke. Atrial fibrillation and ischemic heart disease are more frequent in patients with cardioembolic infarction, hypertension and diabetes in patients with lacunar stroke, and vascular peripheral disease, hypertension, diabetes, previous transient ischemic attack and chronic obstructive pulmonary disease in patients with atherothrombotic infarction. This review aims to present updated data on risk factors for acute ischemic stroke as well as to describe the usefulness of new and emerging vascular risk factors in stroke patients. | Adrià Arboix | 2015 | World Journal of Clinical Cases2015，3，5： | 29 |
| 12 | Prognostic value of preoperative serum tumor markers in gastric cancer显示文摘AIM:To evaluate the prognostic value of preoperative carcinoembryonic antigen(CEA), carbohydrate antigen(CA)19-9, and CA50 in patients undergoing D2 resection.METHODS:We evaluated 363 patients with gastric cancer who underwent gastrectomy at our hospital from January 2006 to December 2009. Blood samples were obtained from each patient within 1 wk before surgery. The cut-off values for serum CEA, CA19-9,and CA50 were 5 ng/mL, 37 U/mL, and 20 U/mL, respectively. The correlation between preoperative tumor marker levels and prognosis was studied by means of univariate and multivariate analyses.RESULTS:The preoperative serum positive rates of CEA, CA19-9 and CA50 were 24.0%, 18.9% and24.5%, respectively. The positivity rate of serum CEA was significantly correlated with age(P < 0.001), sex(P = 0.022), tumor size(P = 0.007) and depth of invasion(P = 0.018); CA19-9 with tumor size(P = 0.042)and lymph node metastasis(P < 0.001); and CA50 onlywith lymph node metastasis(P = 0.001). In multivariate analysis, tumor size, T category, N category, vascular or neural invasion, and adjuvant chemotherapy were independent prognostic factors for overall survival. CA19-9 had an independent prognostic significance in patients without adjuvant chemotherapy(P = 0.027).CONCLUSION:Preoperative serum CEA, CA19-9 and CA50 are prognostic in patients with gastric cancer. Only CA19-9 is an independent prognostic factor after surgery without adjuvant chemotherapy. | Ze-Bo Huang Xin Zhou Jun Xu Yi-Ping Du Wei Zhu Jian Wang Yong-Qian Shu Ping Liu | 2014 | World Journal of Clinical Oncology2014，5，2： | 30 |
| 13 | Current views of the relationship between Helicobacter pylori and Henoch-Schonlein purpura in children显示文摘Helicobacter pylori(H. pylori) is one of the factors involved in the pathogenesis of various gastrointestinal diseases and may play a potential role in certain extraintestinal diseases. H. pylori infection are mainly acquired during childhood, and it has been reported that in endemic areas of China the infection rates are extraordinarily higher in HSP children, particular those with abdominal manifestations. Furthermore, eradication therapy may ameliorate Henoch-Schonlein purpura(HSP) manifestations and decrease the recurrence of HSP. Therefore, results suggested that detection of H. pylori infection by appropriate method ought to be applied in HSP children. Current evidences indicate that local injury of gastric mucosa and immunological events induced by H. pylori infection are involved in the development of HSP. Increased serum Ig A, cryoglobulins, C3 levels, autoimmunity, proinflammatory substances and molecular mimicry inducing immune complex and cross-reactive antibodies caused by H. pylori infection might play their roles in the course of HSP. However, there are no investigations confirming the causality between H. pylori infection and HSP, and the pathogenesis mechanism is still unclear. More bench and clinical studies need to be executed to elaborate the complex association between H. pylori and HSP. | Li-Jing Xiong Meng Mao | 2016 | World Journal of Clinical Pediatrics2016，5，1： | 30 |
| 14 | Evolution,current status and advances in application of platelet concentrate in periodontics and implantology显示文摘Platelet concentrates(PC) [platelet-rich plasma(PRP) and platelet-rich fibrin(PRF)] are frequently used for surgical procedures in medical and dental fields,particularly in oral and maxillofacial surgery,plastic surgery and sports medicine.The objective of all these technologies is to extract all the elements from a blood sample that could be used to improve healing and promote tissue regeneration.Although leukocyte rich and leukocyte poor PRP's have their own place in literature,the importance of non-platelet components in a platelet concentrate remains a mystery.PC have come a long way since its first appearance in 1954 to the T-PRF,A-PRF and i-PRF introduced recently.These PC find varied applications successfully in periodontics and implant dentistry as well.However,the technique of preparation,standing time,transfer process,temperature of centrifuge,vibration,etc.,are the various factors for the mixed results reported in the literature.Until the introduction of a proper classification of terminologies,the PC were known by different names in different countries and by different commercial companies which also created a lot of confusion.This review intends to clarify all these confusion by briefing the exact evolution of PC,their preparation techniques,recent advances and their various clinical and technical aspects and applications. | Amit Arvind Agrawal | 2017 | World Journal of Clinical Cases2017，5，5： | 28 |
| 15 | Surgical strategy for bile duct cancer:Advances and current limitations显示文摘The aim of this review is to describe recent advances and topics in the surgical management of bile duct cancer.Radical resection with a microscopically negative margin(R0)is the only way to cure cholangiocarcinoma and is associated with marked survival advantages compared to margin-positive resections.Complete resection of the tumor is the surgeon’s ultimate aim,and several advances in the surgical treatment for bile duct cancer have been made within the last two decades.Multidetector row computed tomography has emerged as an indispensable diagnostic modality for the precise preoperative evaluation of bile duct cancer,in terms of both longitudinal and vertical tumor invasion.Many meticulous operative procedures have been established,especially extended hepatectomy for hilar cholangiocarcinoma,to achieve a negative resection margin,which is the only prognostic factor under the control of the surgeon.A complete caudate lobectomy and resection of the inferior part of Couinaud’s segmentⅣcoupled with right or left hemihepatectomy has become the standard surgical procedure for hilar cholangiocarcinoma,and pyloruspreserving pancreaticoduodenectomy is the first choice for distal bile duct cancer.Limited resection for middle bile duct cancer is indicated for only strictly selected cases.Preoperative treatments including biliary drainage and portal vein embolization are also indicated for only selected patients,especially jaundiced patients anticipating major hepatectomy.Liver transplantation seems ideal for complete resection of bile duct cancer,but the high recurrence rate and decreased patient survival after liver transplant preclude it from being considered standard treatment.Adjuvant chemotherapy and radiotherapy have a potentially crucial role in prolonging survival and controlling local recurrence,but no definite regimen has been established to date.Further evidence is needed to fully define the role of liver transplantation and adjuvant chemo-radiotherapy. | Nobuhisa Akamatsu Yasuhiko Sugawara Daijo Hashimoto | 2011 | World Journal of Clinical Oncology2011，2，2： | 27 |
| 16 | Tourette syndrome associated with attention deficit hyperactivity disorder: The impact of tics and psychopharmacological treatment options显示文摘Tourette syndrome(TS) is a neurodevelopmental disorder characterized by multiple chronic motor and vocal tics beginning in childhood. Several studies describe the association between TS and attention deficit hyperactivity disorder(ADHD). Fifty percent of children diagnosed with ADHD have comorbid tic disorder. ADHD related symptoms have been reported in 35% to 90% of children with TS. Since ADHD is the most prevalent comorbid condition with TS and those with concomitant TS and ADHD present with considerable psychosocial and behavioral impairments, it is essential for clinicians to be familiar with these diagnoses and their management. This paper highlights the association between treating ADHD with stimulants and the development of tic disorders. The two cases discussed underscore the fact that children with TS may present with ADHD symptomatology prior to the appearance of any TS related symptoms. Appropriate management of TS in a patient diagnosed with ADHD can lead to quality of life improvements and a reduction in psychosocial impairments. | Olumide O Oluwabusi Susan Parke Paul J Ambrosini | 2016 | World Journal of Clinical Pediatrics2016，5，1： | 27 |
| 17 | History of the infantile hepatic hemangioma:From imaging to generating a differential diagnosis显示文摘We aim to provide an up-to-date summary of infantile hepatic hemangioma(IHH) and its misnomers and to dialectically present the differential diagnosis of these rare entities of the liver.Eligible peer-reviewed articles on hepatic infantile hemangiomas,published between 2000 and 2015,were reviewed for this study.IHH is the most common hepatic vascular tumor in children.Once a liver mass is identified in an infant,the differential diagnosis ranges from vascular malformations to benign and malignant tumors including mesenchymal hamartoma,hepatoblastoma,metastatic neuroblastoma,so careful physical examination,imaging studies,and,if indicated,tumor markers and biopsy,are of pivotal importance to ascertain the correct diagnosis.Despite the benign nature of IHHs,some of these lesions may demand medical and/or surgical intervention,especially for multiple and diffuse IHH.Complications can include hepatomegaly,hypothyroidism and cardiac failure.Therefore,a close follow-up is required until complete involution of the lesions.We propose an algorithm to guide the physicians towards the proper management of hepatic lesions. | Maria Gnarra Gerald Behr Alison Kitajewski June K Wu Sudha A Anupindi Carrie J Shawber Nick Zavras Dimitrios Schizas Chris Salakos Konstantinos P Economopoulos | 2016 | World Journal of Clinical Pediatrics2016，5，3： | 27 |

| 19 | Endoscopic diagnosis of extrahepatic bile duct carcinoma:Advances and current limitations显示文摘The accurate diagnosis of extrahepatic bile duct carcinoma is difficult,even now.When ultrasonography(US)shows dilatation of the bile duct,magnetic resonance cholangiopancreatography followed by endoscopic US(EUS)is the next step.When US or EUS shows localized bile duct wall thickening,endoscopic retrograde cholangiopancreatography should be conducted with intraductal US(IDUS)and forceps biopsy.Fluorescence in situ hybridization increases the sensitivity of brush cytology with similar specificity.In patients with papillary type bile duct carcinoma,three biopsies are sufficient.In patients with nodular or infiltrating-type bile duct carcinoma,multiple biopsies are warranted,and IDUS can compensate for the limitations of biopsies.In preoperative staging,the combination of dynamic multidetector low computed tomography(MDCT)and IDUS is useful for evaluating vascular invasion and cancer depth infiltration.However,assessment of lymph nodes metastases is difficult.In resectable cases,assessment of longitudinal cancer spread is important.The combination of IDUS and MDCT is useful for revealing submucosal cancer extension,which is common in hilar cholangiocarcinoma.To estimate the mucosal extenextension,which is common in extrahepatic bile duct carcinoma,the combination of IDUS and cholangioscopy is required.The utility of current peroral cholangioscopy is limited by the maneuverability of the“baby scope”.A new baby scope(10 Fr),called“SpyGlass”has potential,if the image quality can be improved.Since extrahepatic bile duct carcinoma is common in the Far East,many researchers in Japan and Korea contributed these studies,especially,in the evaluation of longitudinal cancer extension. | Kiichi Tamada Jun Ushio Kentaro Sugano | 2011 | World Journal of Clinical Oncology2011，2，5： | 26 |
| 20 | Eosinophilic chronic rhinosinusitis in East Asians显示文摘Chronic rhinosinusitis(CRS) is a common disease worldwide, with a prevalence rate of 5%-15% in the general population. CRS is currently classified into two types: CRS with and without nasal polyps. CRS may also be divided into eosinophilic CRS(ECRS) and non-ECRS subtypes based on the presence of tissue eosinophilic infiltration or not. There are significant geographic and ethnic differences in the tissue eosinophilic infiltration, which is predominant in Western white patients and less common in East Asians, despite an increasing tendency for its prevalence in East Asia countries. ECRS differs significantly from non-ECRS in clinical characteristics, treatment outcomes and strategies, and underlying pathogenic mechanisms. ECRS commonly demonstrates more severe symptoms, polyp diseases with a higher incidence of bilateral polyps and sinonasal diseases on computed tomography, and the increase in blood eosinophils. ECRS is considered a special and recalcitrant subtype of CRS, commonly with poor treatment outcomes compared to non-ECRS. The differentiation of specific subtypes and clinical features of CRS will be important for developing novel treatment strategies and improving treatment outcomes for individual phenotypes of CRS. This review discusses clinical features, diagnosis, treatment and prognosis of ECRS in East Asians. | En-Tong Wang Yan Zheng Peng-Fei Liu Li-Juan Guo | 2014 | World Journal of Clinical Cases2014，2，12： | 26 |
