Introduction. Kallmann syndrome is a genetic disorder marked by hypogonadotropic hypogonadism and anosmia. Patients with Kallmann syndrome have low circulating testosterone levels and low gonadotropin levels, whereas other pituitary hormones are normal. The treatment is based on sex steroid replacement with the aim to restore normal pubertal development and includes attempts to restore fertility by using gonadotropin-releasing hormones. Ultrasound examination of the testicles is a very useful complement to determine and monitor the precise testicular volume, which is an important prognostic factor for future fertility. Case Report. At the age of 18, the patient was suspected of having Kallmann syndrome and was referred to an endocrinologist. After three months of testosterone therapy, the patient was sent for an ultrasound of the testicles. The right testicle measured 16 x 6 mm, the left testicle 10 x 5 mm, both with a discrete marginal circular dichroism signal. One year after the first testicular ultrasound, the patient came for a checkup. The right testicle measured 14 x 5 mm, the left testicle 11 x 5 mm, stationary structure. Conclusion. The diagnosis of Kallmann syndrome is often delayed, because hypogonadotropic hypogonadism is usually not apparent until puberty, and individuals with anosmia are often unaware of this sensory deficit. In this case, late recognition of the syndrome, as well as late initiation of therapy, did not give satisfactory results.
介绍。卡尔曼综合征是一种以促性腺功能减退和嗅觉缺失为特征的遗传性疾病。Kallmann综合征患者循环睾酮水平低,促性腺激素水平低,而其他垂体激素正常。治疗是基于性类固醇替代,目的是恢复正常的青春期发育,包括尝试使用促性腺激素释放激素来恢复生育能力。超声检查睾丸是一个非常有用的补充,以确定和监测精确的睾丸体积,这是一个重要的预后因素,为未来的生育能力。病例报告。18岁时,患者被怀疑患有卡尔曼综合征,并被转介给内分泌学家。经过三个月的睾丸激素治疗后,患者被送去做睾丸超声检查。右睾丸尺寸为16 × 6mm,左睾丸尺寸为10 × 5mm,均具有离散的边缘圆二色信号。在第一次睾丸超声检查一年后,病人来做检查。右睾丸尺寸为14 × 5mm,左睾丸尺寸为11 × 5mm,结构固定。结论。Kallmann综合征的诊断常常被推迟,因为性腺激素促性腺功能减退通常直到青春期才显现出来,而嗅觉缺失的个体通常没有意识到这种感觉缺陷。在这种情况下,较晚的识别综合征,以及较晚的开始治疗,并没有给出令人满意的结果。

Introduction. Multiple myeloma is the second most common malignant hemopathy. The average incidence of this disease in our country is 4.2-6.7/100,000 inhabitants per year. Despite significant progress in the overall survival over the past 20 years, only 10-15% of patients achieve long-term remission and an average survival that corresponds to the average life expectancy of the general human population. The current recommendations for the treatment of multiple myeloma are globally based on the results of randomized clinical trials in which only 10-40% of patients are treated, which is why the analysis of the results of the patients treated outside of randomized clinical trials, the so-called ?Real-World Evidence? data, is very important. Diagnosis and treatment of multiple myeloma - Real-World Evidence. Through presentations of the cases from routine clinical practice, multiple myeloma treatment modalities are presented in accordance with modern recommendations for diagnosis and treatment, as well as the multiple myeloma phase of the disease: treatment approach in newly diagnosed patients; treatment of the first relapse; and treatment of the second and subsequent relapses. Conclusion. The analysis of Real-World Evidence data indicates significant differences between clinical and laboratory characteristics of patients treated outside randomized clinical trials in comparison to the randomized clinical trials participants, with an significant impact to the therapeutic approach, course and outcome of the disease, consequently leading to the necessity of further Real- World Evidence analyzes and their inclusion in the current recommendations for multiple myeloma diagnosis and treatment
介绍。多发性骨髓瘤是第二常见的恶性血液病。我国每年的平均发病率为4.2-6.7/10万居民。尽管在过去20年中总生存率有了显著的进步,但只有10-15%的患者实现了长期缓解,平均生存率相当于一般人群的平均预期寿命。目前多发性骨髓瘤的治疗建议是基于随机临床试验的结果,其中只有10-40%的患者接受了治疗,这就是为什么对随机临床试验之外接受治疗的患者的结果进行分析,即所谓的“真实世界证据”。数据,非常重要。多发性骨髓瘤的诊断和治疗-真实世界的证据。通过对来自常规临床实践的病例的介绍,根据现代诊断和治疗建议,以及新诊断患者的多发性骨髓瘤阶段的治疗方法,介绍了多发性骨髓瘤的治疗方式;第一次复发的治疗;治疗第二次及以后的复发。结论。对真实世界证据数据的分析表明,与随机临床试验参与者相比,随机临床试验外接受治疗的患者的临床和实验室特征存在显著差异,这对疾病的治疗方法、病程和结局有显著影响。因此,需要进一步的真实世界证据分析,并将其纳入当前多发性骨髓瘤诊断和治疗的建议中

Introduction. Embolization into the systemic circulation through the persistent foramen ovale is known as paradoxical embolization. Coexistence of paradoxical embolism with pulmonary thromboembolism is rare and it requires detailed examination. The objective of this study was to present an unusual case of stroke that was complicated by the occurrence of pulmonary thromboembolism, with thrombosis of the superior mesenteric artery, and arterial infarction of numerous visceral organs, a few days after its onset. Case Report. A 60-year-old female patient was admitted to the Emergency Center with clinical symptoms of acute ischemic stroke, with sudden left hemiparesis. Computed tomography showed a fresh ischemia in the basin of the right anterior cerebral artery. The initial clinical course was favorable, with gradual regression of neurological symptoms. On the seventh day of hospitalization, the patient presented with a sudden worsening of symptoms. Computed tomography confirmed multiple infarctions of the liver, spleen and both kidneys, partial thrombosis of the superior mesenteric artery, as well as thrombosis of both pulmonary arteries and two fresh ischemic zones, namely right temporal and parieto-occipital, cortico- subcortical. A persistent foramen ovale was found by transesophageal echocardiography, which also confirmed the existence of an atrial septal aneurysm. In the further course, there was an improvement of symtoms. The patient was referred for further rehabilitation therapy. A surgical closure of persistent foramen ovale was indicated. Conclusion. Paradoxical embolism remains a pathology rarely mentioned by clinicians, although it can affect the functional and vital status and prognosis of the patient. Good cardiac evaluation and detection of persistent foramen ovale in every patient with embolic ischemia is of great importance.
介绍。栓塞通过持续卵圆孔进入体循环称为矛盾栓塞。矛盾栓塞与肺血栓栓塞共存是罕见的,需要详细检查。本研究的目的是提出一个不寻常的中风病例,并发肺血栓栓塞,肠系膜上动脉血栓形成,许多内脏器官动脉梗死,几天后发病。病例报告。60岁女性患者,临床表现为急性缺血性脑卒中,伴有突发性左偏瘫。计算机断层扫描显示右脑前动脉盆区有新发缺血。最初的临床过程是有利的,神经症状逐渐消退。住院第7天,患者突然出现症状恶化。计算机断层扫描证实肝、脾、双肾多发梗死,肠系膜上动脉部分血栓形成,双肺动脉及右侧颞、顶枕、皮质-皮质下两个新鲜缺血区血栓形成。经食道超声心动图发现一个持续的卵圆孔,也证实了房间隔动脉瘤的存在。在进一步的治疗过程中,症状有所改善。病人被转介接受进一步的康复治疗。顽固性卵圆孔手术封闭。结论。矛盾栓塞仍然是一种病理很少被临床医生提及,虽然它可以影响患者的功能和生命状态和预后。良好的心脏评估和持续卵圆孔的检测对每一个栓塞性缺血患者都是非常重要的。

Introduction. Osteoarthritis is a degenerative rheumatic disease of the peripheral joints. It mostly affects one joint, usually the hip and knee joints, as well as the distal interphalangeal joints of the wrist and thumb carpometacarpal joint. The clinical symptoms include pain, swelling, stiffness, crepitus, muscle atrophy, subluxation, as well as reduced joint mobility, greatly affecting the quality of life of patients. The aim of this study was to assess the quality of life of patients with knee osteoarthritis and determine whether there is a difference in the quality of life of patients with unilateral and patients with bilateral knee osteoarthritis. Material and Methods. The study was designed as a retrospective study including 60 patients, 30 patients with unilateral gonarthrosis and 30 patients with bilateral gonarthrosis. The EuroQoL five dimensions questionnaire was used to assess the quality of life. Results. There is no statistically significant difference in the quality of life between individuals with unilateral and bilateral knee osteoarthritis, but there is a significant positive correlation between the pain intensity and difficulties in the domains of quality of life. Conclusion. People with osteoarthritis of the knee mostly take painkillers and have a good or excellent response to therapy. There is no statistically significant difference in the quality of life among people with unilateral and bilateral knee osteoarthritis. There is a significant positive correlation between the pain intensity and difficulties in the domains of quality of life. There is a significant negative correlation between the perception of general health and all five domains of quality of life.
介绍。骨关节炎是一种周围关节退行性风湿病。它主要影响一个关节,通常是髋关节和膝关节,以及手腕和拇指的远端指间关节腕掌关节。临床表现为疼痛、肿胀、僵直、肌力萎缩、半脱位,关节活动能力降低,严重影响患者的生活质量。本研究的目的是评估膝骨关节炎患者的生活质量,确定单侧膝骨关节炎患者和双侧膝骨关节炎患者的生活质量是否存在差异。材料和方法。本研究设计为回顾性研究,包括60例患者,30例单侧关节病患者和30例双侧关节病患者。EuroQoL五维度问卷用于评估生活质量。结果。单侧和双侧膝骨关节炎患者的生活质量没有统计学上的显著差异,但疼痛强度和生活质量方面的困难之间存在显著的正相关。结论。患有膝骨关节炎的人大多服用止痛药,对治疗有很好的或极好的反应。单侧和双侧膝骨关节炎患者的生活质量没有统计学上的显著差异。疼痛强度与生活质量之间存在显著的正相关关系。总体健康感知与生活质量的所有五个领域之间存在显著的负相关。

The importance of supplementation with vitamin D and minerals for achieving maximum effects in the treatment of osteoporosis 补充维生素D和矿物质对骨质疏松症治疗的重要性
Pub Date : 2022-01-01 DOI: 10.2298/mpns22s2028m

Introduction. Vitamin D is known to regulate calcium and phosphate metabolism. It plays an essential role in maintaining a healthy mineralized skeleton and it is also an immunomodulatory hormone. Experimental studies have shown that vitamin D has significant biologic activities on the innate and adaptive immune systems. Animal studies have demonstrated that administration of vitamin D or its metabolites leads to changes in the occurrence and progression of various immune-related diseases. This supports the clinical and epidemiological data that link vitamin D with the incidence and severity of many disorders, such as psoriasis, multiple sclerosis, rheumatoid arthritis, type 1 diabetes, and infectious diseases. In recent decades, interest in vitamin D has increased exponentially, particularly as a vitamin D deficit has been associated with multiple diseases, and globally, there appears to be a high vitamin D deficiency. Osteoporosis prevention. Recent literature states that for the prevention of hypovitaminosis D in children, a daily recommended dose of 400-800 international units (IU) from 0 months to 3 years is required. For ages up to 18, the dose increases to 1000 IU, and from 19 to 70+ the dose is up to 1500 IU. In treating hypovitaminosis D, higher doses than preventive doses are recommended. For ages 0 to 12 months, they vary from 1000 to 1500 IU, while after the age of 9, therapeutic doses increase to 4000 IU. Osteoporosis therapy. In osteoporosis therapy, two groups of drugs are most often used - antiresorptive and anabolic. Of the antiresorptive preparations, bisphosphonates are the most important - the gold standard in treating osteoporosis, the first drug of choice. Conclusion. Circulating vitamin D has an important physiological role. It is necessary to provide enough vitamin D daily to ensure stable concentrations in the circulation and ensure optimal benefits of vitamin D. Recommendations for vitamin D supplementation differ in terms of preventive versus therapeutic doses. If a person is diagnosed with osteoporosis, before the introduction of antiresorptive or anabolic therapy, it is necessary to determine the method of administration of the appropriate dose of vitamin D. In the treatment of osteoporosis bisphosphonates are the gold standard; in addition to vitamin D.
介绍。维生素D可以调节钙和磷酸盐的代谢。它在维持健康的矿化骨骼中起着至关重要的作用,也是一种免疫调节激素。实验研究表明,维生素D对先天免疫系统和适应性免疫系统具有显著的生物活性。动物研究表明,服用维生素D或其代谢物可导致各种免疫相关疾病的发生和进展发生变化。这支持了将维生素D与许多疾病的发病率和严重程度联系起来的临床和流行病学数据,如牛皮癣、多发性硬化症、类风湿性关节炎、1型糖尿病和传染病。近几十年来,人们对维生素D的兴趣呈指数级增长,特别是维生素D缺乏与多种疾病有关,而且在全球范围内,维生素D似乎严重缺乏。预防骨质疏松症。最近的文献表明,为了预防儿童维生素D缺乏症,从0个月到3岁,每天推荐剂量为400-800国际单位(IU)。对于18岁以下的人,剂量增加到1000 IU,从19岁到70岁以上的人,剂量高达1500 IU。在治疗维生素D缺乏症时,建议服用高于预防剂量的剂量。0到12个月的婴儿,剂量从1000到1500国际单位不等,而9岁以后,治疗剂量增加到4000国际单位。骨质疏松症的治疗。在骨质疏松症治疗中,两组药物最常被使用-抗吸收和合成代谢。在抗吸收制剂中,双磷酸盐是最重要的——治疗骨质疏松症的黄金标准,首选药物。结论。循环维生素D具有重要的生理作用。每天提供足够的维生素D是必要的,以确保血液循环中的浓度稳定,并确保维生素D的最佳效益。关于补充维生素D的建议在预防剂量和治疗剂量方面有所不同。如果一个人被诊断为骨质疏松症,在引入抗吸收或合成代谢治疗之前,有必要确定适当剂量的维生素d的给药方法。在治疗骨质疏松症中,双膦酸盐是金标准;除了维生素D之外

Current principles of follicular lymphoma treatment 滤泡性淋巴瘤治疗的现行原则
Pub Date : 2022-01-01 DOI: 10.2298/mpns22s1062r
M. Radojković
Over the last 10-15 years, the prognosis of patients with follicular lymphoma has improved, and for the majority of patients, follicular lymphoma is a chronic disease with ten years of overall survival of around 80%. Nevertheless, a certain subset of patients belongs to high-risk follicular lymphoma with early relapses and progressive disease, poor outcomes, and much shorter survival, and there is still no standard approach in the treatment of high-risk follicular lymphoma. Treatment of follicular lymphoma is highly heterogeneous, ranging from a ?watch and wait? strategy to intensive immunochemotherapy, and needs to be individualized to each patient. An early stage of the disease can be treated with involved-field radiotherapy, which has curative potential. Follicular lymphoma in the advanced stage is still an incurable disease. Standard first-line treatment is a combination of an anti-CD20 antibody (rituximab) and chemotherapy, followed by antibody maintenance. In relapse, treatment with novel anti-CD20 monoclonal antibody-obinutuzumab in combination with chemotherapy. The combination of lenalidomide and rituximab shows good results in patients with relapses and refractory follicular lymphoma, but also as a first-line treatment. An option for elderly patients with comorbidities is rituximab monotherapy. Autologous or allogeneic stem cell transplantation may be an option for a small group of selected patients. In the past decade development of novel targeted agents such as phosphoinositide three kinase inhibitors and immunotherapies (CD20/CD3 bispecific antibody, chimeric antigen receptor T cell therapy) demonstrate the efficiency of chemotherapy-free approach not only for relapsed/refractory patients but also in first-line treatment. A better understanding of the clinical and biological features of follicular lymphoma patients is necessary to improve treatment outcomes in the future.
在过去的10-15年中,滤泡性淋巴瘤患者的预后有所改善,对于大多数患者来说,滤泡性淋巴瘤是一种慢性疾病,10年总生存率约为80%。然而,有一部分患者属于高危滤泡性淋巴瘤,复发早,病情进展,转归差,生存期短,目前高危滤泡性淋巴瘤的治疗尚无标准方法。滤泡性淋巴瘤的治疗是高度异质性的,从观察和等待?强化免疫化疗的策略,需要个体化治疗。疾病的早期阶段可以用有治愈潜力的受累场放射治疗。晚期滤泡性淋巴瘤仍然是一种无法治愈的疾病。标准的一线治疗是抗cd20抗体(利妥昔单抗)和化疗的联合,然后是抗体维持。复发时,采用新型抗cd20单克隆抗体-比努妥珠单抗联合化疗。来那度胺联合利妥昔单抗治疗复发难治性滤泡性淋巴瘤疗效良好,也可作为一线治疗。有合并症的老年患者的一个选择是利妥昔单抗单药治疗。自体或异体干细胞移植可能是一小部分选定患者的一种选择。在过去的十年中,新型靶向药物如磷酸肌苷三激酶抑制剂和免疫疗法(CD20/CD3双特异性抗体,嵌合抗原受体T细胞疗法)的发展证明了无化疗方法不仅对复发/难治性患者有效,而且在一线治疗中也很有效。更好地了解滤泡性淋巴瘤患者的临床和生物学特征对于改善未来的治疗效果是必要的。

Nevertheless, a certain subset of patients belongs to high-risk follicular lymphoma with early relapses and progressive disease, poor outcomes, and much shorter survival, and there is still no standard approach in the treatment of high-risk follicular lymphoma. Treatment of follicular lymphoma is highly heterogeneous, ranging from a ?watch and wait? strategy to intensive immunochemotherapy, and needs to be individualized to each patient. An early stage of the disease can be treated with involved-field radiotherapy, which has curative potential. Follicular lymphoma in the advanced stage is still an incurable disease. Standard first-line treatment is a combination of an anti-CD20 antibody (rituximab) and chemotherapy, followed by antibody maintenance. In relapse, treatment with novel anti-CD20 monoclonal antibody-obinutuzumab in combination with chemotherapy. The combination of lenalidomide and rituximab shows good results in patients with relapses and refractory follicular lymphoma, but also as a first-line treatment. An option for elderly patients with comorbidities is rituximab monotherapy. Autologous or allogeneic stem cell transplantation may be an option for a small group of selected patients. In the past decade development of novel targeted agents such as phosphoinositide three kinase inhibitors and immunotherapies (CD20/CD3 bispecific antibody, chimeric antigen receptor T cell therapy) demonstrate the efficiency of chemotherapy-free approach not only for relapsed/refractory patients but also in first-line treatment. A better understanding of the clinical and biological features of follicular lymphoma patients is necessary to improve treatment outcomes in the future.","PeriodicalId":87940,"journal":{"name":"Calcutta medical review","volume":"15 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2022-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"88709971","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}

Introduction. Primary immune thrombocytopenia is a chronic acquired autoimmune disorder that is characterized by isolated thrombocytopenia (<100 x109/L) and the absence of any underlying cause. Treatment of primary immune thrombocytopenia. While splenectomy has a curable potential, it carries long-term risk of infection and thromboembolic complications. Therefore, the use of splenectomy has declined with the advent of rituximab and agonists of thrombopoietin receptors. The efficacy of rituximab is good for the short-term outcome, and the majority of patients will relapse. On the other hand, agonists of thrombopoietin receptors induce remission in only 10-30% of patients after treatment discontinuation, and long-term treatment is often required. Health - related quality of life. Immune thrombocytopenia and its treatments may affect the entire spectrum of patients? lives, encompassing daily activities, emotional health, energy level, fatigue, and work productivity. Primary immune thrombocytopenia World Impact Survey was conducted to discern how immune thrombocytopenia and associated treatments affect patient lives. Concerns about unstable platelet count, low energy levels, inability to exercise, and reduced participation in hobbies and work had the greatest negative impact. While most patients reported ?good health?, nonetheless half of patients reported a negative impact on their emotional well-being that worsened with increasing burden of disease and was often substantial. Conclusion. Although several important improvements have been made in immune thrombocytopenia treatment algorithms, there is still room for improvement. One of the possible options could be early, intensive treatment of immune thrombocytopenia, which might reduce the risk of disease progression and consequently improve patients? quality of life.
介绍。原发性免疫性血小板减少症是一种慢性获得性自身免疫性疾病,其特征是孤立性血小板减少(<100 × 109/L),没有任何潜在原因。原发性免疫性血小板减少症的治疗。虽然脾切除术有治愈的潜力,但它有长期感染和血栓栓塞并发症的风险。因此,脾切除术的使用随着利妥昔单抗和血小板生成素受体激动剂的出现而减少。利妥昔单抗短期疗效良好,多数患者会复发。另一方面,血小板生成素受体激动剂在停药后仅能缓解10-30%的患者,通常需要长期治疗。与健康相关的生活质量。免疫性血小板减少症及其治疗可能影响整个患者谱?生活,包括日常活动、情绪健康、能量水平、疲劳和工作效率。原发性免疫性血小板减少症世界影响调查进行辨别免疫血小板减少症和相关治疗如何影响患者的生活。对血小板计数不稳定、能量水平低、无法运动、减少参与爱好和工作的担忧是最大的负面影响。虽然大多数患者报告“身体健康”?尽管如此,仍有一半的患者报告说,他们的情绪健康受到了负面影响,这种影响随着疾病负担的增加而恶化,而且往往是实质性的。结论。尽管在免疫血小板减少治疗算法方面已经取得了一些重要的改进,但仍有改进的余地。一个可能的选择是对免疫性血小板减少症进行早期强化治疗,这可能会降低疾病进展的风险,从而改善患者的病情。生活质量。

Introduction. Myelodysplastic syndromes represent clonal neoplastic disorders characterized by hematological dysplasia, ineffective hematopoiesis, cytopenia, and increased risk of transformation to acute myeloid leukemia. Material and Methods. A literature review was conducted using the following bibliographic databases: Google Scholar, MEDLINE, and Kobson. The recommendations for diagnosis, classification, and prognosis are based on expert opinions grounded on a review of the literature and contemporary recommendations for diagnosis and prognosis in myelodysplastic syndrome. Diagnosis and classification. Diagnosis of myelodysplastic syndrome should be based on detailed patient and family history, physical examination, and comprehensive blood examinations in to exclude all other causes of cytopenia and dysplasia. Mandatory for myelodysplastic syndrome diagnosis is cytology of blood and bone marrow, bone marrow biopsy with immunohistology and cytogenetics. 2016 World Health Organization classification should be used for myelodysplastic syndrome diagnosis. SF1B3 genetic analysis is recommended in patients with suspected myelodysplastic syndrome with ringed sideroblasts and p53 mutation status. Prognosis. Revised International Prognostic Scoring System for myelodysplastic syndrome (IPSS-R) risk score should be defined for every patient in order to determine prognosis. The next-generation sequencing could provide additional diagnostic and prognostic information, particularly in young transplant candidates. Conclusion. Myelodysplastic syndrome diagnosis is based on the 2016 World Health Organization classification. The prognosis should be based on the Revised International Prognostic Scoring System with the possible addition of genetic analysis.
介绍。骨髓增生异常综合征是一种克隆性肿瘤疾病,其特征是血液系统发育异常、造血功能低下、细胞减少,以及转化为急性髓系白血病的风险增加。材料和方法。使用以下书目数据库进行文献综述:Google Scholar、MEDLINE和Kobson。骨髓增生异常综合征的诊断、分类和预后的建议是基于对文献的回顾和对骨髓增生异常综合征的诊断和预后的当代建议的专家意见。诊断和分类。骨髓增生异常综合征的诊断应基于详细的患者和家族史、体格检查和全面的血液检查,以排除所有其他导致细胞减少和增生异常的原因。骨髓增生异常综合征的强制性诊断是血液和骨髓细胞学检查,骨髓活检与免疫组织学和细胞遗传学。2016年世界卫生组织分类应用于骨髓增生异常综合征的诊断。SF1B3基因分析推荐用于疑似骨髓增生异常综合征伴环状铁母细胞和p53突变状态的患者。预后。修订的国际骨髓增生异常综合征预后评分系统(IPSS-R)的风险评分应该为每个患者定义,以确定预后。下一代测序可以提供额外的诊断和预后信息,特别是在年轻的移植候选人中。结论。骨髓增生异常综合征的诊断是基于2016年世界卫生组织的分类。预后应以修订后的国际预后评分系统为基础,并可能加入遗传分析。

Unusual presentation of dermal microcalcifications on mammography images: A case report 乳房x线摄影图像上皮肤微钙化的不寻常表现:1例报告
Pub Date : 2022-01-01 DOI: 10.2298/mpns2210305l

Introduction. Calcifications and microcalcifications are mineral deposits in the breast tissue. Breast calcifications are a common mammographic finding, present on over 80% of images, and they are usually benign. Characteristics such as size, shape, number, distribution pattern, location, density, and other findings help determine the pathology. Dermal calcifications of the breast are superficial and benign calcifications that are usually found on the sebaceous glands of the skin. In some cases, calcifications can be the first marker of underlying cancer development. They may be associated with the presence of ductal carcinoma in situ or even invasive ductal carcinoma that has spread to the surrounding breast tissue. By correct identification of benign calcifications as such, unnecessary interventions and use of limited resources can be avoided. Case Report. A 66-year-old female patient presented for a regular mammography check-up. On the previous mammographic examination, she was categorized as bilateral breast imaging reporting and data system 1. The new mammography images showed numerous newly formed grouped microcalcifications at the junction of the lower quadrants of the right breast, and a stereotactic vacuum-assisted biopsy was indicated. During the biopsy attempt, the image guided biopsy program did not detect any calcifications in the parenchyma or in any projection and therefore it did not allow the biopsy procedure to continue after several attempts. Examination of the right breast skin revealed lesions treated by the patient for a few weeks; a repeat mammogram was performed and it was observed that the calcifications were of dermal origin. Conclusion. Dermal calcifications are mostly tiny, about the size of skin pores, single or clustered, and often have a calcified rim surrounding a lucent center. However, dermal calcifications deserve a special attention, because they sometimes lack a lucent center and simulate grouped intraparenchymal calcifications that require careful monitoring or biopsy.
介绍。钙化和微钙化是乳房组织中的矿物质沉积。乳房钙化是一种常见的乳房x光检查结果,在80%以上的图像上都有,通常是良性的。诸如大小、形状、数量、分布模式、位置、密度等特征和其他发现有助于确定病理。乳腺真皮钙化是一种表面的良性钙化,通常发生在皮肤的皮脂腺上。在某些情况下,钙化可能是潜在癌症发展的第一个标志。它们可能与导管原位癌的存在有关,甚至与浸润性导管癌已经扩散到周围乳腺组织有关。通过正确识别良性钙化,可以避免不必要的干预和有限资源的使用。病例报告。一位66岁的女性患者来做常规乳房x光检查。既往乳腺x线检查,患者被归类为双侧乳腺影像学报告及资料系统1。新的乳房x线摄影图像显示在右乳房下象限交界处有许多新形成的成组微钙化,并指示进行立体定向真空辅助活检。在活检过程中,图像引导活检程序未在实质或任何投影中检测到任何钙化,因此在多次尝试后不允许继续活检程序。右乳皮肤检查显示患者治疗了几个星期的病变;再次进行乳房x光检查,发现钙化源自皮肤。结论。真皮钙化大多很小,约皮肤毛孔大小,单个或成簇,常有钙化的边缘围绕着明亮的中心。然而,真皮钙化值得特别注意,因为它们有时缺乏明亮的中心,并模拟成组的实质内钙化,需要仔细监测或活检。

Introduction. Upper extremity venous aneurysms and aneurysms of the neck are rare, unlike the lower extremity venous aneurysms. Only a few cases of upper extremity venous aneurysms have been described in the literature. The aim of the study was to find the best way to treat upper extremity venous aneurysms and the aneurysms of the neck region. Case Report. A 40-year-old female patient reported to the Emergency Center due to the swelling in the supraclavicular region. Color Doppler ultrasonography was performed and a saccular subclavian aneurysm was found, at the junction with the internal jugular vein, with signs of rupture presenting with locoregional hematoma spillage measuring 19 x 13 mm. Complete laboratory tests were performed, followed by computed tomography phlebography, where a partially thrombosed aneurysm was described in the angle between the internal jugular vein and subclavian vein, with a maximum diameter of 25 mm. The patient was hospitalized and treated conservatively. Six days after the onset of symptoms, magnetic resonance phlebography was performed, which did not show the previously described aneurysm of the left venous angle. Three months after the onset of symptoms, a control magnetic resonance phlebography was performed, which showed an aneurysm in the region of the junction of the left internal jugular vein and subclavian vein again, with a maximum diameter of 20 x 13 mm. Conclusion. Clinical examination and color Doppler ultrasound should certainly be the first-line of diagnosis, while magnetic resonance phlebography and computed tomography phlebography are the gold standard for aneurysm monitoring. Asymptomatic aneurysms and aneurysms with mild symptoms are best treated conservatively.
介绍。上肢静脉动脉瘤和颈部动脉瘤是罕见的,不像下肢静脉动脉瘤。文献中只有少数上肢静脉动脉瘤的病例被报道过。本研究的目的是寻找治疗上肢静脉动脉瘤和颈部动脉瘤的最佳方法。病例报告。一名40岁女性患者因锁骨上区域肿胀而向急救中心报告。彩色多普勒超声检查发现一囊状锁骨下动脉瘤,位于颈内静脉交界处,有破裂迹象,局部血肿溢出,尺寸为19 x 13 mm。进行了完整的实验室检查,随后进行了计算机断层摄影静脉摄影,在颈内静脉和锁骨下静脉之间的角度处描述了部分血栓形成的动脉瘤,最大直径为25毫米。患者住院并接受保守治疗。症状出现6天后,进行了磁共振静脉造影,没有显示先前描述的左静脉角动脉瘤。症状出现3个月后行对照磁共振静脉造影,再次在左侧颈内静脉与锁骨下静脉交界处发现动脉瘤,最大直径为20 x 13 mm。结论。临床检查和彩色多普勒超声当然是诊断的第一线,而磁共振血管造影和计算机断层血管造影是动脉瘤监测的金标准。无症状和症状轻微的动脉瘤最好保守治疗。
