Background: Several cases of Graves’ disease were recently reported in individuals vaccinated against severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2). Objective: To determine characteristics and patterns of Graves’ disease occurring following SARS-CoBV-2 vaccination. Methods: PubMed search up to March 31st, 2022. Search terms are Graves’ disease, SARS-Cov-2, vaccine, COVID-19. Case reports, case series, review articles and pertinent in vitro studies are reviewed. Results: Review of literature revealed 28 cases (19 women) of new onset and 5 cases (4 women) of relapses of Graves’ disease after receiving different types of vaccines against coronavirus disease 2019 (COVID-19). Onset of hyperthyroid symptoms started 2-60 days after vaccination and occurred more frequently after the first vaccine dose (n=13) than after the second dose (n=5). In 70% of cases (23 of 33), the implicated agent was the m-RNA based vaccine of Pfizer-BioNtech. Severity of Graves’ disease symptoms was generally moderate and controlled by anti-thyroid medications (mainly methimazole) and beta-adrenergic blockers. The course of Graves’ disease is unclear as patients are still receiving therapy. No specific risk factors could be defined that may increase predisposition to the COVID-19 vaccine-induced Graves’ disease. Mechanisms of development of Graves’ disease after COVID-19 vaccination are unclear but may be related to the phenomena of molecular mimicry or autoimmune/inflammatory syndrome by adjuvants (ASIA). Conclusions: The timing of onset of symptoms of Graves’ disease in relation to the administration of COVID-19 vaccine strongly suggests a causal relationship. Physicians should be aware of the occurrence of this uncommon adverse effect.
背景:最近在接种了严重急性呼吸综合征冠状病毒2 (SARS-CoV-2)疫苗的个体中报告了几例格雷夫斯病。目的:了解sars - cov -2疫苗接种后发生Graves病的特点和模式。方法:PubMed检索截止到2022年3月31日。搜索词是格雷夫斯病,SARS-Cov-2,疫苗,COVID-19。病例报告,病例系列,评论文章和相关的体外研究进行了审查。结果:文献回顾发现,接种不同类型新型冠状病毒病(COVID-19)疫苗后新发Graves病28例(女性19例),复发Graves病5例(女性4例)。甲状腺功能亢进症状开始于接种疫苗后2-60天,并且在第一次接种疫苗后(n=13)比第二次接种疫苗后(n=5)发生的频率更高。在70%的病例(33例中的23例)中,涉及的病原体是辉瑞- biontech公司基于m-RNA的疫苗。Graves病症状的严重程度一般为中度,并由抗甲状腺药物(主要是甲巯咪唑)和β -肾上腺素能阻滞剂控制。由于患者仍在接受治疗,格雷夫斯病的病程尚不清楚。没有明确的危险因素可能增加COVID-19疫苗诱导的格雷夫斯病的易感性。COVID-19疫苗接种后Graves病的发生机制尚不清楚,但可能与佐剂引起的分子模仿或自身免疫/炎症综合征(ASIA)现象有关。结论:格雷夫斯病症状的发病时间与COVID-19疫苗的接种有很强的因果关系。医生应该意识到这种不常见的不良反应的发生。

Tension pneumocephalus is an unusual bad life-threatening neurosurgical emergency, this is the equivalent of tension pneumothorax. This often follows head trauma, epidural injections, complicating neurological spinal, craniofacial or sinus surgery. This is a forty-five-year-old man that was involved in a road traffic accident, was referred for a computed tomography of the brain on account of altered consciousness, irrational behavior, and restlessness. A non-contrast enhanced computed tomography of the brain was done, this demonstrated multiple areas of cortical discontinuity in the facial and skull vaults in keeping with fractures, extensive negative density (HU: -968) hypodensity in the frontal region bilaterally causing marked inferior displacement of both frontal lobes of the brain, with associated splaying of the interhemispheric fissure likened to the ‘Mount Fuji sign’ of severe/tension pneumocephalus. Pockets of negative density hypodensities are also noted in both cerebral hemispheres in keeping with pneumatoceles are also demonstrated. Generalized effacement of sulci and gyri in keeping with cerebral edema is also demonstrated. The outcome of the patient in the peripheral center was not known as at the time of this report, because all effort to get across to the patient and relations proved abortive. We present a case of tension pneumocephalus following road transport accident, to review the computed tomographic features due to its peculiar presentation.
张力性小头症是一种不寻常的严重危及生命的神经外科急诊,相当于张力性肺气肿。这通常发生在头部创伤、硬膜外注射、复杂的神经脊髓、颅面或鼻窦手术之后。这是一名45岁的男子,他卷入了一场道路交通事故,由于意识改变、非理性行为和烦躁不安,被转诊进行脑部计算机断层扫描。对大脑进行了非对比增强计算机断层扫描,这表明面部和颅骨拱顶的多个皮质不连续区域与骨折保持一致,双侧额叶区域出现广泛的负密度(HU:-968)低密度,导致大脑两额叶明显下移位,与半球间裂的相关张开类似于严重/紧张性肺炎球菌的“富士山征”。在两个大脑半球也发现了负密度低密度的小袋,与气膨出一致。脑沟和回的广泛消失与脑水肿也得到了证实。在本报告发布时,外围中心患者的结果尚不清楚,因为所有与患者和亲属沟通的努力都被证明是徒劳的。我们报告了一例道路运输事故后的张力性肺炎球菌,以回顾由于其特殊表现而引起的计算机断层扫描特征。

Introduction: Tardive dyskinesia (TD) includes involuntary choreiform or athetoid movements of the jaw, lower face, tongue, and extremities, developing in association with the use of an antipsychotic medication, and may develop in about 20 to 40 percent of patients who require long-lasting hospitalization. In the present study, the prevalence of this condition has been measured among an elderly group of schizophrenic patients. Methods: One hundred and one elderly schizophrenic patients, who were hospitalized in the chronic section of a community psychiatric hospital, were selected for the present cross-sectional study. Abnormal Involuntary Movement Scale (AIMS) was employed to screen for patients with schizophrenia who also had TD. Scale for Assessment of Positive Symptoms, Scale for Assessment of Negative Symptoms, Schedule for Assessment of Insight, and Clinical Global Impressions – Severity of illness, as well, had been used as ancillary scales for evaluation of severity of general psychopathology of schizophrenia, and comparing the TD patients with the group of patients without TD, for probing the intervening parameters. Results: While abnormal movements were clear in 38.61% (n=39) of elderly schizophrenic patients, only seven of them (6.93 %) could be diagnosed as TD, based on the above-mentioned criteria. All of them were using conventional antipsychotic medications, accompanied with anticholinergic medications. Among TD patients, three cases had only abnormal facial and oral movements, one patient had atypical facial and oral movements as well as anomalous extremity movements, one patient had irregular facial and oral movements in addition to unusual trunk movements, and lastly, two patients had nonstandard extremity movements. In addition, around 71% of patients with TD were aware of their unusual movements. Between-group analysis did not show any significant difference between patients with TD and patients without TD in age, duration of illness, positive symptoms, negative symptoms, insight, and general psychopathology. Conclusion: According to the findings of the present study, the prevalence of Tardive Dyskinesia among elderly schizophrenic patients, who were using typical antipsychotic medications, is very lower than what has been indicated thus far.
引言:迟发性运动障碍(TD)包括与使用抗精神病药物有关的下巴、下脸、舌头和四肢的非自愿舞蹈状或无神论运动,可能在约20%至40%需要长期住院治疗的患者中发生。在本研究中,测量了一组老年精神分裂症患者中这种情况的患病率。方法:选择101名在社区精神病院慢性科住院的老年精神分裂症患者进行横断面研究。采用异常非自愿运动量表(AIMS)筛查同样患有TD的精神分裂症患者。阳性症状评估量表、阴性症状评估量量表、洞察力评估表和临床总体印象-疾病严重程度,已被用作评估精神分裂症一般精神病理学严重程度的辅助量表,并将TD患者与无TD患者组进行比较,以探讨干预参数。结果:虽然38.61%(n=39)的老年精神分裂症患者的异常运动是明显的,但根据上述标准,其中只有7人(6.93%)可以诊断为TD。所有患者均使用常规抗精神病药物,并伴有抗胆碱能药物。在TD患者中,3例仅面部和口腔运动异常,1例面部和口腔动作不典型,肢体运动异常,一例面部和嘴巴动作不规则,躯干运动异常,最后,两例肢体运动不规范。此外,约71%的TD患者意识到自己的异常动作。组间分析显示,TD患者和非TD患者在年龄、病程、阳性症状、阴性症状、洞察力和一般精神病理学方面没有任何显著差异。结论:根据本研究的结果,在使用典型抗精神病药物的老年精神分裂症患者中,迟发性运动障碍的患病率远远低于迄今为止的研究结果。

Background: Trachoma is a communicable infection of the eye by certain strains of the Chlamydia trachomatis. It is the principal cause of loss of sight globally. Mass drug administration (MDA) with azithromycin is a foundation stone of World Health Organization (WHO)’s global struggle to eradicate trachoma by 2020. Aims: The main objectives of the campaign's third monitoring are to check improvement of interventions and improvement of quality across times and activities implemented in seven selected districts of Ibb and Al-Hodeida governorates, Yemen. Methods: A community based cross-sectional coverage survey was performed. 68 divisions were selected per selected districts of the two governorates. A disconnect Results Entry Form for each district surveyed was finished, saved and uploaded directly into the online Coverage Survey Analysis Tool to check improvement of interventions and improvement of quality across times and activities implemented. Results: The national campaign for MDA covers 966 villages in 6 districts of Ibb and Al-Hodeidah governorates by 1932 healthcare workers. A total number of beneficiaries who were monitored from 476 homes reached 3,077, of whom 2,755 (90%, coverage rate) took the dose. The availability rates of trachoma medicines were ranged from 82% to 91%. The improper arrangement of treatment sessions rate was 17%, the incorrect position of the dose pole was 6%, while the correct records of drugs scored the rate of 99%, and the proper storage of drugs rate was 70%. The community collaboration during the treatment campaign the acceptable rate was 92%, while 3% exhibited unacceptable behaviors towards the treatment campaign. Conclusion: In this survey, the national campaign for MDA in the 966 villages reach the target threshold (i.e. 90%) for effective coverage; with proper rates for the availability of trachoma medicines, good people reactions towards taking treatment, and the community collaboration; while bad rates for the improper arrangement of treatment sessions, the incorrect position of the dose pole and the preparation dosages by MDA team. Hence, programmatic enhancement should be made for the future campaign to achieve the estimated thresholds.
背景:沙眼是一种由沙眼衣原体的某些菌株引起的眼睛传染性感染。它是全球失明的主要原因。阿奇霉素大规模给药(MDA)是世界卫生组织(世卫组织)到2020年根除沙眼的全球斗争的基石。目的:该运动第三次监测的主要目标是检查在也门伊卜省和荷台达省7个选定地区实施的干预措施的改进情况和质量改进情况。方法:以社区为基础进行横断面调查。这两个省的每个选定地区选出了68个县。完成每个被调查地区的断开连接结果输入表,并将其保存并直接上传到在线覆盖率调查分析工具中,以检查不同时间和实施活动的干预措施改进情况和质量改善情况。结果:由1932名医护人员开展的全国MDA运动覆盖了Ibb省和Al-Hodeidah省6个区的966个村庄。从476个家庭监测的受益人总数达到3,077人,其中2,755人(覆盖率90%)服用了该剂。沙眼药物的可得率为82% ~ 91%。治疗时段安排不当率为17%,剂量杆位置不正确率为6%,药品记录正确率为99%,药品存放正确率为70%。治疗活动期间的社区合作可接受率为92%,而3%的人对治疗活动表现出不可接受的行为。结论:在本次调查中,全国966个村的MDA运动达到了有效覆盖率的目标阈值(即90%);沙眼药物的适当可得率、人们对治疗的良好反应以及社区合作;治疗时段安排不当、剂量杆位置不正确、MDA组制剂剂量不正确的发生率较高。因此,应加强方案,使今后的运动达到估计的阈值。

Sheppard Siegal Syndrome (Familial Mediterranean fever): The Value of Serum Amyloid a in the Diagnosis and Treatment Decision 谢泼德西格尔综合征(家族性地中海热):血清淀粉样蛋白a在诊断和治疗决策中的价值
Pub Date : 2022-04-21 DOI: 10.31579/2690-1919/243

Background: Sheppard Siegal syndrome was first described in 1945 by Sheppard Siegal. He described in details an extraordinary syndrome that was often undiagnosed because it was not clearly understood. The syndrome described by Siegal is characterized by recurrent attacks of fever, and commonly begins during childhood, and may begin as early as seven months. Attacks of the syndrome usually last two to three days and, often recur every few weeks. Siegal emphasized that progressive renal disease in the form of amyloidosis or chronic glomerulonephritis is the most serious organ involvement. Four mutations in the MEFV gene have been reported to account for 86% of the mutations causing Sheppard Siegal syndrome. Colchicine has been used for the treatment and prevention amyloidosis. Patients and methods: The father of a 3.5-year Iraqi boy (Born on the 19th of March, 2018) of Kurdish origin living in Dubai consulted us during September, 2021 about the appropriate treatment of his son who was experiencing recurrent attacks of high fever over about one year. He consulted us after consulting few physicians in Dubai who were prescribing oral and injectable acetaminophen for the symptomatic control of fever during the attacks. The case was studied and an evidenced-based recommendation is presented in this paper. Results: The attacks of fever were persisting for few days and were not generally associated with mo other significant symptoms other than the general ill health and tiredness that can be associate with fevers of various etiologies. Between the attacks, the boy was in good health and had normal activity. The father was unaware of a similar illness in their relatives. Serum amyloid A (EIA) was performed during the last attack of fever during August, 2021, and was very high (517mg/L), as the normal level is less than 6.40517mg/L. Analysis of regions of the MEFV gene showed no pathogenic variants were detected. Conclusion: We have recommended monitoring serum amyloid A during attack free periods, and initiate colchicine therapy if serum amyloid A was found high to prevent the development of amyloidosis according to the evidence provided by Berkun et al (2007).
背景:谢帕德-西格尔综合征最早由谢帕德·西格尔于1945年描述。他详细描述了一种特殊的综合征,这种综合征往往因为不清楚而无法诊断。西格尔描述的综合征以反复发作的发烧为特征,通常始于儿童时期,最早可能在七个月内开始。该综合征的发作通常持续两到三天,通常每隔几周复发一次。西格尔强调,淀粉样变性或慢性肾小球肾炎形式的进行性肾脏疾病是最严重的器官受累。据报道,MEFV基因的四个突变占导致Sheppard-Sigal综合征的突变的86%。秋水仙碱已被用于治疗和预防淀粉样变性。患者和方法:一名居住在迪拜的库尔德裔3.5岁伊拉克男孩(2018年3月19日出生)的父亲于2021年9月向我们咨询了对其儿子的适当治疗,该儿子在大约一年多的时间里反复发高烧。在咨询了迪拜的几位医生后,他咨询了我们,这些医生在袭击期间为控制发烧症状开了口服和注射对乙酰氨基酚的处方。本文对该案例进行了研究,并提出了基于证据的建议。结果:发烧发作持续了几天,除了可能与各种病因的发烧相关的一般健康不良和疲劳外,通常与其他显著症状无关。在两次袭击之间,男孩身体状况良好,活动正常。父亲没有意识到他们的亲人也有类似的疾病。血清淀粉样蛋白A(EIA)是在2021年8月最后一次发烧期间进行的,非常高(517mg/L),因为正常水平低于6.40517mg/L。对MEFV基因区域的分析显示,没有检测到致病性变异。结论:根据Berkun等人(2007)提供的证据,我们建议在无发作期监测血清淀粉样蛋白A,如果发现血清淀粉样肽A含量高,则开始秋水仙碱治疗,以预防淀粉样变性的发展。

Siegal emphasized that progressive renal disease in the form of amyloidosis or chronic glomerulonephritis is the most serious organ involvement. Four mutations in the MEFV gene have been reported to account for 86% of the mutations causing Sheppard Siegal syndrome. Colchicine has been used for the treatment and prevention amyloidosis. Patients and methods: The father of a 3.5-year Iraqi boy (Born on the 19th of March, 2018) of Kurdish origin living in Dubai consulted us during September, 2021 about the appropriate treatment of his son who was experiencing recurrent attacks of high fever over about one year. He consulted us after consulting few physicians in Dubai who were prescribing oral and injectable acetaminophen for the symptomatic control of fever during the attacks. The case was studied and an evidenced-based recommendation is presented in this paper. Results: The attacks of fever were persisting for few days and were not generally associated with mo other significant symptoms other than the general ill health and tiredness that can be associate with fevers of various etiologies. Between the attacks, the boy was in good health and had normal activity. The father was unaware of a similar illness in their relatives. Serum amyloid A (EIA) was performed during the last attack of fever during August, 2021, and was very high (517mg/L), as the normal level is less than 6.40517mg/L. Analysis of regions of the MEFV gene showed no pathogenic variants were detected. Conclusion: We have recommended monitoring serum amyloid A during attack free periods, and initiate colchicine therapy if serum amyloid A was found high to prevent the development of amyloidosis according to the evidence provided by Berkun et al (2007).","PeriodicalId":93114,"journal":{"name":"Journal of clinical research and reports","volume":" ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2022-04-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"46772570","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Aim: In this study, it is aimed to examine the subjective experiences of nurses who worked voluntarily in COVID-19 services at the beginning of the pandemic. It is known the most psychologically affected group among healthcare professionals working with COVID-19 patients is nurses. Materials and Methods: The research was carried out using the narrative technique, the descriptive qualitative research methods. The data were collected with the "Nurse Introductory Information Form" and "Semi-structured Questionnaire for the Story of Being a Nurse in Fighting the Pandemic". Data were analyzed using the Story Evaluation Scale. Results: Seven nurses between the ages of 23-36, working in 3 different hospitals, participated in the study. Nurses stated they voluntarily care for patients between 2 weeks-17 months with the ethical values of benefit, respect for the individual, equality-justice, feelings of love, compassion, mercy. Emotional expressions in nurses' stories were determined as 'sadness (n=3), remorse, gratitude, pride (n=2), fear (n=4), anxiety (n=2), panic, worry, uneasiness, satisfaction, inadequacy’. Nurses used the metaphors of 'Motherhood, Heroism, Life Risk, Bomb Squad, Being a Trench on the Front, Warrior, Going to Fire' for their fight against COVID-19. Nurses reported that they experienced problems such as sweating, shortness of breath, limitation of communication, difficulty in care, decreased water intake while working with protective equipment. It has been reported family and peer support, team solidarity, belief in fulfilling sacred duty, suggestion, patience facilitate coping. Conclusions: It is necessary to increase the psychological resilience of nurses and to defend their rights in the political arena.
目的:本研究旨在调查大流行初期自愿参与COVID-19服务的护士的主观体验。众所周知,在与COVID-19患者一起工作的医疗保健专业人员中,心理受影响最大的群体是护士。材料与方法:本研究采用叙事手法、描述性质的研究方法。数据是通过“护士介绍信息表”和“护士在抗击大流行中的故事半结构化问卷”收集的。使用故事评价量表对数据进行分析。结果:7名护士参与研究,年龄23-36岁,分别在3家不同医院工作。护士们表示,她们自愿在2周到17个月的时间里照顾病人,并本着利益、尊重个人、平等正义、爱的感觉、同情和仁慈的道德价值观。确定护士故事中的情绪表达为“悲伤(n=3)、悔恨、感激、骄傲(n=2)、恐惧(n=4)、焦虑(n=2)、恐慌、担心、不安、满足、不足”。护士们用“母性、英雄主义、生命危险、拆弹小组、前线战壕、战士、奔赴战场”来比喻她们与COVID-19的斗争。护士报告说,她们在使用防护设备时遇到了出汗、呼吸短促、交流受限、护理困难、饮水减少等问题。据报道,家庭和同伴的支持、团队团结、履行神圣职责的信念、建议、耐心有助于应对。结论:提高护士的心理弹性,维护护士在政治舞台上的权利是必要的。

铁是一种与许多生理功能有关的基本元素。在胰腺β细胞中,它们是铁-S簇蛋白的组成部分,而铁-S簇蛋白是胰岛素生成和加工的必要条件。就线粒体而言,作为呼吸链的一个组成部分,它有助于ATP和活性氧(ROS)的产生,从而诱导β细胞去极化,从而导致钙基胰岛素释放的增强。重要的是,在铁细胞数量方面建立了一个明显的微调,以保证正常的铁供应,同时避免铁过载。实际上,考虑到与氧的巨大反应以及自由基的产生,铁超载可能导致细胞氧化损伤,鉴于ROS发育的正常升级以及抗氧化酶作用的可用性较低,对这种情况具有易感性的细胞。因此,我们利用常用的搜索引擎利用MeSH进行了系统的综述;铁代谢;糖尿病;haemochromatosis;thallasemia;阿尔茨海默病,帕金森病;弗里德里希的共济失调;铁稳态;铁结合蛋白;转铁结合铁(TBI);非TBINTBI);二价金属转运体I(DMT1);;运铁素胰岛淀粉样多肽;锌输送器zip14;伴侣蛋白-聚CR结合蛋白(PCBPs);mitoferrin (Mfrn);Fe-S簇-酶CDKAL1;hepcidin;hephaestin;frataxin;不稳定铁池;ABCT7;PDX1; MafA;博士学位;播出;Miner 1;妊娠DM;ferroptosis;;运铁素铁超载及治疗;脑毒性;GIT;从1980年到2022年至今。我们共找到4500篇文章,从中选择了135篇文章纳入本综述。未进行meta分析。本综述的主要目的是更好地了解β细胞中的铁稳态模式,以及在这种情况下它们的损伤模式的变化。异常的铁储存/伴侣蛋白如何导致糖尿病。

Cystitis glandularis is a proliferative disorder of the urinary bladder which has tended to be associated with glandular metaplasia of the transitional cells that line the urinary bladder. Cystitis glandularis tends to be closely related to cystitis cystica with which it commonly does exist. Cystitis cystica represents a proliferative or reactive changes which tend to occur within von Brunn nests which do acquire luminal spaces and become cystically dilated, and cystitis may undergo glandular metaplasia which does represent cystitis glandularis or the cystitis may undergo intestinal type of metaplasia which is referred to as intestinal type of cystitis. Cystitis cystica and cystitis glandularis is a very common incidental finding. Cystitis cystica and glandularis tend to develop I the setting of chronic irritation or inflammation of the urinary bladder mucosa. Cystitis cystica and glandularis tend to be frequently found in co-existence with interrelated lesions and they represent benign simulators of invasive carcinoma of the urinary bladder. With regard to mode of manifestation and diagnosis, cystitis cystica and cystitis glandularis tend to be diagnosed incidentally based upon: findings of urinary bladder lesions at cystoscopy undertaken for some other reason or upon incidental finding of a urinary bladder lesion following the undertaking of radiology imaging (ultra-sound scan, or computed tomography (CT) scan or magnetic resonance imaging (MRI) scan undertaken for something else. The patient may also manifest with lower urinary tract symptoms of urinary frequency, urgency, urge incontinence or poor flow of urine or difficulty in initiating urine. On rare occasions when the ureteric orifices are involved the patient may manifest with one sided loin pain or bilateral loin pain if both ureteric orifices are obstructed by the urinary bladder lesion. In severe cases of bilateral ureteric obstruction there may be evidence of impairment of renal function. Haematuria could also be a mode of presentation. Ultrasound scan of renal tract could demonstrate a polypoidal thickening of the wall of the urinary bladder usually in the trigone of the bladder but in extensive cases the thickening could be all over the urinary bladder and in cases where the ureteric orifices are obstructed there may be evidence of hydroureter and hydronephrosis. CT scan may show hyper-vascular polypoid mass within the urinary bladder, and MRI scan could demonstrate a hyperintense vascular core with encompassing low-intensity signal. These radiology imaging features are non-specific and would differentiate the urinary bladder lesion from invasive urothelial carcinoma. Diagnosis of the cystitis tends to be made based upon histopathology examination and immunohistochemistry staining studies of biopsy specimens or the trans-urethral resection specimens of the urinary bladder lesions. Microscopy pathology examination of the specimens tend to demonstrate: (a) abundant urothelial von Bru
腺性膀胱炎是一种膀胱增生性疾病,通常与膀胱移行细胞的腺化生有关。腺性膀胱炎往往与通常存在的囊性膀胱炎密切相关。囊性膀胱炎是一种增殖性或反应性的变化这种变化往往发生在冯·布伦巢中它会获得腔隙并变得囊性扩张,膀胱炎可能会发生腺性化生这确实代表腺性膀胱炎或者膀胱炎可能会发生肠型化生这被称为肠型膀胱炎。囊性膀胱炎和腺性膀胱炎是非常常见的偶然发现。膀胱炎和腺性膀胱炎往往在膀胱黏膜慢性刺激或炎症的情况下发展。囊性膀胱炎和腺性膀胱炎往往与相关病变共存,它们是浸润性膀胱癌的良性模拟物。就表现方式和诊断而言,囊性膀胱炎和腺性膀胱炎往往是偶然诊断的依据:由于其他原因在膀胱镜检查中发现膀胱病变,或在放射学成像(超声扫描、计算机断层扫描或磁共振成像)扫描后偶然发现膀胱病变。患者还可能出现尿频、尿急、急迫性尿失禁或尿流不畅或排尿困难等下尿路症状。在少数情况下,当输尿管口受累时,患者可能表现为单侧腰痛或双侧腰痛,如果两个输尿管口被膀胱病变阻塞。在严重的情况下,双侧输尿管梗阻可能有肾功能损害的证据。血尿也可能是一种表现方式。肾脏的超声扫描可以显示膀胱壁的息肉样增厚,通常在膀胱三角区,但在广泛的情况下,增厚可能遍及整个膀胱,在输尿管口阻塞的情况下,可能有输尿管积水和肾积水的证据。CT扫描可显示膀胱内高血管性息肉样肿块,MRI扫描可显示高血管性核心伴周围低强度信号。这些影像学特征是非特异性的,可以将膀胱病变与浸润性尿路上皮癌区分开来。膀胱炎的诊断往往基于活检标本或膀胱病变经尿道切除标本的组织病理学检查和免疫组织化学染色研究。标本的显微病理检查往往显示:(a)丰富的尿路上皮von Brunn巢,往往表现出模糊的小叶状内翻分布,以及非浸润性生长的证据,以及生长和与表面的不同连接,(b)腺性膀胱炎病例中有柱状或立方细胞的腺体样腔,(c)囊性膀胱炎病例中囊性扩张的腔或囊性腔充满嗜酸性液体。(e)细胞缺乏显著的异型性、有丝分裂活性、基质反应和肌肉侵袭,偶尔出现退行性异型性。腺性膀胱炎病例的免疫荧光研究倾向于显示-连环蛋白的均匀膜表达,没有细胞质或核定位。囊性膀胱炎和腺性膀胱炎的免疫组化染色倾向于以下各种标志物呈阳性:GATA3、CK7(全层)、CK20(伞细胞)、p63(基底细胞层)、uroplakin II/III、血栓调节蛋白、β -连环蛋白(膜)和E-cadherin。囊性膀胱炎和腺性膀胱炎患者免疫组化染色CDX2、绒毛蛋白(Villin)、MUC2、MUC5AC、β -连环蛋白(catenin)(核)呈阴性。囊性膀胱炎和腺性膀胱炎的一些鉴别诊断包括:von Brunn巢型增生、尿路上皮原位癌、倒置性尿路上皮乳头状瘤、巢型浸润性尿路上皮癌和微囊型尿路上皮癌。 在极少数情况下,囊性膀胱炎和腺性膀胱炎可能同时伴有尿路上皮癌,因此每个检查囊性膀胱炎和腺性膀胱炎标本的病理学家都需要对膀胱病变的各个区域进行彻底的检查,以绝对确定膀胱病变中没有同步的恶性肿瘤。囊性膀胱炎的治疗确实需要去除刺激源或膀胱炎症源,包括异物、长期导尿管、膀胱结石等,并经尿道切除膀胱病变或病变。在极少数情况下进行了膀胱切除术。膀胱输尿管梗阻的患者可能需要在梗阻一侧进行肾造口术,然后由于梗阻部位的疤痕或当疤痕太密时,可能需要切除病变并重新植入输尿管。在肾功能严重损害的情况下,在极少数情况下,透析可能需要作为支持治疗。但对于大多数患者,经尿道膀胱病变切除往往就足够了。

Even though adenocarcinoma of the prostate gland could be lethal in its advanced stage, adenocarcinoma of the prostate gland can be effectively treated when the carcinoma is localized to the prostate gland and when the localized adenocarcinoma is a low-risk or intermediate-risk localized adenocarcinoma of the prostate gland. it is localized. Traditionally, radical prostatectomy (RP) or radical radiotherapy (RT) in the form of either external beam radiotherapy or brachytherapy were utilized to treat all men who have localized adenocarcinoma of the prostate gland as treatment of curative intent. Nevertheless, Radical prostatectomy and radical radiotherapy do tend to be associated with significant risks of post-treatment side effects. Some patients who have localized prostate cancer may not be medically fit as a result of their comorbidities to undergo radical prostatectomy or radical radiotherapy to their prostate cancers. Over recent years a number of less-invasive treatment options are being utilized for the treatment of some localized adenocarcinomas of the prostate gland and some of the treatment options include: Cryotherapy of prostate Cancer; Radiofrequency ablation of prostate cancer, High Intensity Focused Ultrasound Treatment of Prostate Cancer and Irreversible Electroporation of prostate cancer as focal ablation or whole gland ablation. Focal therapy has emerged as a potential form of treatment that can achieve similar oncological outcomes to radical treatment while preserving functional outcomes and decreasing rates of adverse effects. Irreversible electroporation (IRE) is one such form of focal therapy which utilizes pulsatile electrical currents to ablate tissue. This modality of treatment is still in an early research phase, with studies showing that IRE is a safe procedure that can offer good short-term oncological outcomes whilst carrying a lower risk of poor functional outcomes. Irreversible Electroporation (IRE) is a new radiology image-guided tissue ablation which does induce cell death through very short but strong electric fields. IRE had been demonstrated to have preserving properties towards vessels, nerves, as well as the extra-cellular matrix. For this reason, IRE could represent an ideal treatment option for adenocarcinoma where other treatment options including radical prostatectomy and radical radiotherapy tend to unselectively destroy that encompass the prostate cancer and inducing side effects including urinary incontinence as well as sexual dysfunction / impotence. Some results of studies in which IRE had been utilized for the treatment of curative intent of localized low-risk and intermediate-risk adenocarcinomas of the prostate gland had indicated complete efficacy of IRE to the standard of radical prostatectomy and standard radical radiotherapy with regard to the 5-year tumour recurrence rate as well as better preservation of genitourinary function which did prove the safety as well as suitability of IRE for the tr
考虑到IRE往往与良好的短期和中期结果相关,这也往往通常优于放疗和根治性前列腺切除术后的结果,并且事实上,中长期肿瘤学结果往往是好的,可以建议,可以为喜欢维持其泌尿生殖系统功能的低风险和中风险局限性腺癌患者提供IRE,作为治疗目的的一线治疗。被发现患有IRE失败的个体可以接受根治性前列腺切除术或根治性放射治疗,作为治疗目的的二线治疗。最后,需要对IRE进行一项全球多中心试验,以治疗局部低风险、中风险、,以及高危人群和那些有高危人群局限性前列腺癌症的人可以接受辅助治疗,所有这些治疗都应该与长期随访的根治性放疗和根治性前列腺切除术进行比较,以建立共识并制定指导方针。
