Introduction: Blood group information is an integral part of clinical diagnosis using various haematological techniques to understand haematological disorders. Simultaneously, it is mandatory to have clear information on blood groups in case of blood transfusion and related matters. It is important to have complete history of the patients and the subjects including establishment and maintenance of blood banks. Aim: The aim was to study the clinical and physiological manifestations of blood group typing in social groups. Materials and Methods: The present observational study was carried out in four districts (Nainital, Champawat, Pithoragarh and Udham Singh Nagar) of Kumaun region of Uttarakhand, India from March 2018 to March 2019 to record the blood group of students from randomly selected schools and colleges. The collected numerical data was statistically analysed in the form of bar diagram by using Microsoft Excel software. Results: The present survey was carried out during the year 2018 in the colleges, covering 1073 students to understand the blood groups. During the investigation, the majority of students exhibited B+ (242) followed by O+ (237), A+ (208), AB+ (121), O- (15), B- (9), A- (8) and AB- (7) respectively. There were 226 students who refused to give blood sample for blood group typing due to fear and other unexplained reasons. O+ (237) and B+ (242) blood groups were observed as most common blood groups and ABblood group was found only in seven students. Conclusion: The present study yielded information basically on blood group pattern across the population and it can be used by blood donation blood bank societies for collection of blood from various groups.
简介:血型信息是临床诊断的一个组成部分,使用各种血液学技术来了解血液学疾病。同时,在输血和相关事项中,必须明确血型信息。有完整的患者和受试者的病史,包括血库的建立和维持是很重要的。目的:探讨社会人群血型分型的临床和生理表现。材料与方法:本观察性研究于2018年3月至2019年3月在印度北阿坎德邦Kumaun地区的四个地区(Nainital、champaat、Pithoragarh和Udham Singh Nagar)进行,记录随机选择的学校和大学学生的血型。采用Microsoft Excel软件对收集到的数值数据以条形图的形式进行统计分析。结果:本调查于2018年在高校开展,共覆盖1073名学生了解血型。在调查过程中,大多数学生表现为B+(242),其次是O+ (237), A+ (208), AB+ (121), O- (15), B- (9), A-(8)和AB-(7)。有226名学生因害怕或其他无法解释的原因拒绝提供血样进行血型分型。O+(237)和B+(242)是最常见的血型,只有7名学生发现了ab血型。结论:本研究基本掌握了全国人群的血型分布情况,可供献血血库协会采集不同血型的血液使用。

Introduction: The transfusion of blood and blood components is a life-saving procedure in clinical practice. However, it is associated with risks that can range from trivial self-limited Allergic Reactions (AR) to life endangering anaphylactic or haemolytic transfusion reactions. Aim: To analyse the pattern and incidence of transfusion related adverse events and to develop preventive strategies. Materials and Methods: This was a retrospective, observational study conducted at Department of Pathology, PSG Institute of Medical Sciences and Research, Coimbatore, Tamil Nadu, India, on data of Adverse Transfusion Reactions (ATR) reported to the blood bank over a period of 12 years from January 2006 to December 2018. The ATRs were analysed with respect to gender, type of blood component, and nature of the reaction. The data collected were tabulated and the analysis was done using percentages. Results: A total of 1,60,914 units of Whole Blood (WB) and blood components were issued during the study period. A 271 adverse reactions (129 reactions in females and 142 reactions in males) were documented constituting 0.168% of the total products issued, majority were due to packed red cells (0.29%). The incidence of AR was the maximum, accounting for 63.1% of the reactions (n=171, 75 in females and 96 in males) followed by Febrile Non Haemolytic Transfusion Reactions (FNHTR) which were 33.57% (n=91, 42 in males and 49 in females). There were four cases of Transfusion Associated Acute Lung Injury (TRALI), all in males, accounting for 1.48% of the reactions, three cases of anaphylactoid reactions (2 in females and 1 in male) accounting for 1.11% of the total reactions and two cases of haemolytic transfusion reaction (0.73%). Conclusion: The frequency of adverse reactions in the present study is 0.168% (271 out of 1, 60,914 units), majority were due to packed red cells (0.29%). No adverse reactions due to bacterial contamination occurred during the study period. It is important to ensure education of nursing staff, interns, and residents regarding the correct procedure of blood transfusion, identification of adverse reactions and appropriate remedial measures for the same.
在临床实践中,输血和血液成分是一项挽救生命的程序。然而,它与各种风险相关,从微不足道的自限性过敏反应(AR)到危及生命的过敏或溶血性输血反应。目的:分析输血相关不良事件的类型和发生率,制定预防策略。材料和方法:这是一项回顾性观察性研究,在印度泰米尔纳德邦哥印拜陀PSG医学科学与研究所病理学系进行,研究对象是2006年1月至2018年12月期间向血库报告的输血不良反应(ATR)数据。对atr进行性别、血型成分和反应性质的分析。将收集到的数据制成表格,并使用百分比进行分析。结果:研究期间共发放全血(WB)及血液成分1 60914单位。271例不良反应(女性129例,男性142例)占总发行量的0.168%,大多数是由于红细胞堆积(0.29%)。AR的发生率最高,占63.1%(女性171 75例,男性96例),其次是发热性非溶血性输血反应(FNHTR),占33.57%(男性91 42例,女性49例)。输血相关急性肺损伤(TRALI) 4例,均为男性,占总反应的1.48%;类过敏反应3例(女2例,男1例)占总反应的1.11%;溶血性输血反应2例(0.73%)。结论:本组不良反应发生率为0.168%(271 / 160.914单位),以红细胞堆积为主(0.29%)。研究期间未发生因细菌污染引起的不良反应。重要的是要确保对护理人员、实习生和住院医生进行正确的输血程序、不良反应的识别和适当的补救措施的教育。

Introduction: The Coronavirus Disease-2019 (COVID-19) pandemic has emerged from Wuhan, China in late 2019 and spread across the world in few months. This pandemic has affected people all over the world in terms of not only health but also psychologically, economically and socially. Early diagnosis by Real Time Polymerase Chain Reaction (RT-PCR) test helped the health system to isolate the patient and prevent the spread of the disease in community. Aim: To know the prevalence of asymptomatic COVID-19 infection among healthcare workers. Materials and Methods: This study was a cross-sectional study and focused on early detection of asymptomatic COVID19 infection among Healthcare Workers (HCW) by RT-PCR test. Total of 356 samples were collected of all HCW working in Nootan Medical College and Research Centre Visnagar, Gujarat, India, in month of May 2021. Data were analysed on basis of job profile, working area and vaccination status. Chi-square test was used for statistical analysis. Results: Out of total 356 samples, six were positive showing prevalence of 1.68%. Out of these six positive workers two had exposure to COVID-19 positive patients at home in last 10 days. No significance was found in positivity rate in relation to job profile, working area in hospital and vaccination status. Conclusion: This study reveals low prevalence of asymptomatic infection among HCWs engaged in COVID-19 related duties. The HCWs are at highest risk of contracting infection, hence it is necessary to protect their safety and health as infection among them can spread to other co-workers and patients.

Introduction: Bacterial meningitis among adults is a medical emergency and requires immediate diagnosis as well as immediate treatment. As clinical diagnosis is not always reliable, laboratory isolation along with antimicrobial susceptibility results are crucial. Conventional agar culture methods gives poor sensitivity and delayed results. Automated culture methods like BACTEC are suitable option for culture of sterile fluids beside blood culture. Aim: To determine the bacterial agents causing meningitis in this region, along with their antibiogram by using automated culture system BACTEC FX40. Materials and Methods: This cross-sectional, observational study was conducted between October 2019-September 2020 in Department of Microbiology, Rohilkhand Medical College and Hospital, Bareilly, Uttar Pradesh, India. Cereospinal Fluid (CSF) samples received from medicine Intensive Care Unit (ICU) and wards were processed by inoculating them on BD BACTEC Peds Plus/F bottle and then incubating them on BACTEC BD FX40 system. The bottles flagged and positive were subcultured and further processed according to standard laboratory procedures. The antibiotic sensitivity test was performed from isolated organisms by Kirby-Bauer Disc Diffusion method according to Clinical and Laboratory Standards Institute (CLSI) guidelines. Results: A total of 108 CSF were received for culture by automated methods from patients suspected of meningitis during the study period. Out of them 84 (77.8%) beeped as positive while 24 (22.2%) were sterile. From the positives, 77 showed growth of gram positive cocci, three were gram negative bacilli and four showed growth of environmental and skin contaminants that were excluded from the study. All gram positive cocci were identified as Staphylococcus aureus (S. aureus). The antibiotic sensitivity testing showed 100% sensitivity to vancomycin and linezolid. Only 25 isolates of S. aureus were sensitive to cefoxitin. Both the isolates of Escherichia coli (E. coli) were sensitive to cefazolin, ceftazidime, aztreonam. Pseudomonas aeruginosa (P. aeruginosa) was sensitive to amikacin and piperacillin/tazobactum. Conclusion: A shift in the trend was observed in the aetiology of bacterial meningitis with Methicillin Resistant Staphylococcus aureus (MRSA) as the most predominant isolate among adult population. BACTEC FX40 system was found more sensitive in detecting pathogens over the conventional methods with reduced time to positivity. Early detection of causative organism will facilitate early initiation of suitable antibiotic therapy, thereby reducing mortality and meningitis associated complications.
成人细菌性脑膜炎是一种医疗紧急情况,需要立即诊断和立即治疗。由于临床诊断并不总是可靠的,实验室分离以及抗菌药物敏感性结果至关重要。传统的琼脂培养方法灵敏度差,结果延迟。除血液培养外,BACTEC等自动化培养方法是无菌液体培养的合适选择。目的:利用BACTEC FX40全自动培养系统检测该地区脑膜炎病原菌及其抗生素谱。材料和方法:这项横断面观察性研究于2019年10月至2020年9月在印度北方邦巴雷利罗希尔坎德邦医学院和医院微生物学系进行。重症监护室(ICU)和病房采集的脑脊液(CSF)标本,先接种于BD BACTEC Peds Plus/F瓶,然后在BACTEC BD FX40系统上孵育。标记和阳性的瓶子进行传代培养,并根据标准实验室程序进一步处理。根据临床和实验室标准协会(CLSI)的指南,采用Kirby-Bauer圆盘扩散法对分离的微生物进行抗生素敏感性试验。结果:在研究期间,通过自动方法从疑似脑膜炎患者中收集了108例脑脊液进行培养。其中阳性84例(77.8%),不育24例(22.2%)。在阳性病例中,77例显示革兰氏阳性球菌生长,3例为革兰氏阴性杆菌生长,4例显示环境和皮肤污染物生长,这些均被排除在本研究之外。所有革兰氏阳性球菌鉴定为金黄色葡萄球菌(金黄色葡萄球菌)。药敏试验对万古霉素、利奈唑胺均100%敏感。仅有25株金黄色葡萄球菌对头孢西丁敏感。两株大肠杆菌均对头孢唑林、头孢他啶、氨曲南敏感。铜绿假单胞菌(P. aeruginosa)对阿米卡星和哌拉西林/他唑乳敏感。结论:细菌性脑膜炎的病原学趋势发生了变化,成人中耐甲氧西林金黄色葡萄球菌(MRSA)是最主要的分离物。发现BACTEC FX40系统在检测病原体方面比传统方法更敏感,并且缩短了阳性时间。病原微生物的早期发现将有助于尽早开始适当的抗生素治疗,从而降低死亡率和脑膜炎相关并发症。

Introduction: Coronavirus Disease-2019 (COVID-19), caused by the Severe Acute Respiratory Syndrome Coronavirus 2 (SARSCoV-2) catapulted the need to build, upgrade and expand the number of diagnostic laboratories having molecular capacity. Setting up and sustaining a molecular laboratory especially in the backdrop of a lockdown presented many challenges. The Department of Microbiology, in a tertiary level hospital in Mumbai was one of the first to start the molecular testing laboratory. All other tests performed in the department are accredited as per International Organisation for Standardisation (ISO) 15189:2012 since 2015. However, starting a molecular diagnostic facility for COVID-19 testing presented a unique set of challenges as the organism in question belonged to risk category 2 and had the potential for airborne transmission. Aim: To determine the challenges faced and activities undertaken especially with regards to the role of Quality Management System (QMS) in setting up and sustaining a molecular diagnostic facility during COVID-19 pandemic. Materials and Methods: A retrospective analysis was carried out of experiences and data generated from March 2020 to April 2021 at the Microbiology Department of a tertiary level medical college and hospital in Mumbai, Maharashtra, India. The article included the processes which required and data generated during setting up and sustaining a new molecular testing facility as per the QMS with special reference to the 12 Quality System Essentials (QSE). Quality Indicators (QI) were identified, objectives defined and monitored over the period of the study. It was a descriptive study and statistical analysis was not indicated. Results: All the objectives of the QI were met with. Only 4% staff needed corrective training. Specimen rejection rate pretest and post-test was 0.26% and 0.56%, respectively. Quality control failure was seen in 0.16% runs and Turnaround Time (TAT) deviated beyond 12 hours in 0.52% samples. The run contamination, equipment problems and laboratory associated infections were 0.08%, 0.56% and 0%, respectively. There were no External Quality Assessment (EQAS) failure and negative feedback. Laboratory contamination rate was 1.02%. Definite improvement was observed over time in all identified parameters. Conclusion: Implementation of QMS with specific reference to strengthening QSE is a necessary requirement for achieving quality standards.
导言:由严重急性呼吸综合征冠状病毒2型(SARSCoV-2)引起的2019冠状病毒病(COVID-19)迫切需要建设、升级和扩大具有分子能力的诊断实验室的数量。特别是在封锁的背景下,建立和维持一个分子实验室带来了许多挑战。孟买一家三级医院的微生物科是最早建立分子检测实验室的医院之一。自2015年起,在该部门进行的所有其他测试都获得了国际标准化组织(ISO) 15189:2012的认证。然而,启动用于COVID-19检测的分子诊断设施带来了一系列独特的挑战,因为所讨论的生物体属于风险类别2,并且有可能通过空气传播。目的:确定面临的挑战和开展的活动,特别是在2019冠状病毒病大流行期间,质量管理体系(QMS)在建立和维持分子诊断设施方面的作用。材料与方法:对印度马哈拉施特拉邦孟买一所三级医学院和医院微生物科2020年3月至2021年4月的经验和数据进行回顾性分析。文章包括根据质量管理体系(QMS)建立和维持新的分子检测设施所需的过程和产生的数据,特别参考了12个质量体系要点(QSE)。确定质量指标(QI),确定目标并在研究期间进行监测。这是一项描述性研究,没有进行统计分析。结果:各项指标均达到。只有4%的员工需要纠正培训。试验前和试验后标本拒绝率分别为0.26%和0.56%。质量控制不良率为0.16%,周转时间(TAT)偏差超过12小时的样品为0.52%。运行污染、设备问题和实验室相关感染分别为0.08%、0.56%和0%。无外部质量评价(EQAS)失败和负面反馈。实验室污染率为1.02%。随着时间的推移,所有确定的参数都有明显的改善。结论:实施质量管理体系,加强QSE是实现质量标准的必要条件。

Pub Date : 2022-01-01 DOI: 10.7860/njlm/2022/53058.2592
Zini Chaurasia, Renu Gupta, S. Agarwal
Lipoid pneumonia has been described in as early as 1925, by Laughlen GF, to be a rare variant of pneumonia caused by the inhalation of oil droplets. Around 50% of the patients with lipoid pneumonia are asymptomatic. Here, a case is presented where peritoneal fluid and tissue pieces from various organs of a 12-year-old female were received for examination after autopsy. There was no history of any illness before death. Cytology of fluid revealed features suggestive of endometriosis. Microscopy of lung sections revealed numerous lipid droplets in the alveoli and the interstitium along with a mild inflammatory infiltrate suggestive of lipoid pneumonia. In view of incidental findings in present case report, the occupational history or history of inhalation of oil-based medications becomes very important and should always be investigated. Also, in the absence of any symptoms peritoneal fluid needs to be studied carefully for any pathology.
脂质肺炎早在1925年就被劳伦GF描述为一种罕见的由吸入油滴引起的肺炎。约50%的脂质性肺炎患者无症状。在这里,一个12岁的女孩在尸检后接受了腹膜液和不同器官的组织块的检查。死前没有任何疾病史。液体细胞学显示提示子宫内膜异位症的特征。肺切片镜检显示肺泡和间质中有大量脂滴,伴轻度炎性浸润,提示脂质性肺炎。鉴于本病例报告中的偶然发现,职业史或油类药物吸入史变得非常重要,应始终进行调查。此外,在没有任何症状的情况下,需要仔细研究腹膜液是否有任何病理。

Introduction: Dengue virus of the Flaviviridae family is the causative agent of dengue fever. The Aedes aegypti mosquito is the main vector for its transmission. Though, the cases of dengue fever are mild and self-resolving, there can be fatal complications like Dengue Haemorrhagic Fever (DHF) and Dengue Shock Syndrome (DSS). Aim: To study the trends in the seroprevalence of dengue in serum samples of suspected cases. Materials and Methods: The present study was a cross- sectional study which was conducted from January 2017 to December 2019, at Belagavi Institute of Medical Sciences (BIMS), Belagavi, Karnataka, India. The serum samples were collected from suspected dengue fever cases and tested by Immunoglobulin M (IgM) capture Enzyme Linked Immunosorbent Assay (ELISA), to detect IgM antibody against dengue virus and NS1 capture ELISA for dengue NS1 (nonstructural protein 1) antigen using ELISA kits manufactured by National Institute of Virology (NIV), Pune. The tests were performed according to the manufacturer’s instruction. The data obtained from the study was analysed using descriptive statistics. Results: A total of 8,992 serum samples were tested over a period of three years, of which 1,340 (14.90%) were positive for dengue infection. Among which 1,048 (78.21%) were positive for anti-dengue IgM antibodies, 109 (8.13%) were positive for NS1 antigen and 183 (13.66%) were positive for both. Most affected age group was 11-20 years and male to female ratio is 1.18:1. The seasonal peak was observed in monsoon i.e. month of June (15.52%) followed by August (12.02%). Conclusion: Seroprevalence of dengue infection being critical signifies the importance of detection of both IgM antibodies and NS1 antigen for diagnosis of dengue infection. The study also identifies younger population being at higher risk and also monsoon as the most favourable season for viral transmission in this region and highlights the importance of concerted efforts towards disease control and prevention.
简介:黄病毒科的登革病毒是登革热的病原体。埃及伊蚊是其主要传播媒介。虽然登革热病例较轻且可自行消退,但可能出现致命的并发症,如登革出血热和登革休克综合征。目的:探讨登革热在疑似病例血清中的流行趋势。材料与方法:本研究是一项横断面研究,于2017年1月至2019年12月在印度卡纳塔克邦Belagavi医学科学研究所(BIMS)进行。采集疑似登革热病例血清样本,采用免疫球蛋白M (IgM)捕获酶联免疫吸附试验(ELISA)检测登革热病毒IgM抗体,采用浦那国家病毒学研究所(NIV)生产的ELISA试剂盒检测登革热非结构蛋白1抗原NS1捕获ELISA。这些测试是按照制造商的说明进行的。从研究中获得的数据使用描述性统计进行分析。结果:三年间共检测了8992份血清样本,其中1340份(14.90%)为登革热感染阳性。其中抗登革热IgM抗体阳性1048例(78.21%),NS1抗原阳性109例(8.13%),两者均阳性183例(13.66%)。发病年龄以11-20岁为主,男女比例为1.18:1。季节高峰为季风,即6月(15.52%)次之,8月(12.02%)。结论:登革热感染的血清阳性率是关键,提示IgM抗体和NS1抗原的检测对登革热感染的诊断具有重要意义。该研究还确定了年轻人群的风险更高,季风是该地区病毒传播的最有利季节,并强调了协调一致努力控制和预防疾病的重要性。

Metastatic Sebaceous Carcinoma Presenting as Cheek Nodule: A Rare Case 转移性皮脂腺癌表现为脸颊结节:一例罕见病例
Pub Date : 2022-01-01 DOI: 10.7860/njlm/2022/48938.2558
Ayushi R. Saxena, Ashumi Gupta
Sebaceous Carcinoma is a rare locally aggressive tumour of adnexal epithelium with a potential to metastasize to regional lymph node and distant organs. It constitutes between 1.5 to 5% of all eyelid malignant tumours. After basal cell and squamous cell carcinomas, it ranks third in incidence. Sebaceous carcinoma is seen more commonly in elderly females with average age at diagnosis in mid-sixties. Few cases have been reported in paediatric age group. Sebaceous Gland Carcinoma (SGC) is a slowly progressive tumor that arises usually from the meibomian gland in the eyelid, and has a locally aggressive nature with a tendency for pagetoid spread. The neoplasm is known to masquerade other benign and less malignant lesions. The non-specific clinical symptoms may lead to a delay in diagnosis of sebaceous carcinoma of the eyelid. Less than 120 cases of extra-occular sebaceous cell carcinoma have been reported so far. Here, the authors present a case of 60 years old female patient, who presented with cheek nodule and cytological diagnosis of metastatic sebaceous carcinoma was made based on cytomorphological features.
皮脂腺癌是一种罕见的局部侵袭性附件上皮肿瘤,有可能转移到局部淋巴结和远处器官。它占所有眼睑恶性肿瘤的1.5%到5%。继基底细胞癌和鳞状细胞癌之后,在发病率上排名第三。皮脂腺癌常见于老年女性,平均诊断年龄在60岁左右。在儿童年龄组中报告的病例很少。皮脂腺癌(SGC)是一种缓慢进展的肿瘤,通常起源于眼睑的睑板腺,具有局部侵袭性,有页状扩散的倾向。已知该肿瘤可掩盖其他良性和非恶性病变。非特异性的临床症状可能导致眼睑皮脂腺癌的诊断延迟。不到120例眼外皮脂腺细胞癌被报道到目前为止。在这里,作者报告了一个60岁的女性患者,她表现为脸颊结节,根据细胞形态学特征诊断为转移性皮脂腺癌。

Introduction: Intestinal coccidian parasites known to cause opportunistic infections have increased since the past years and are often indistinguishable from other forms of community- acquired diarrhoea, which suggests a need for proper and rapid diagnostic techniques to recover and identify the organism. Aim: To investigate if Auramine Rhodamine (AR) staining is a sensitive and time conserving staining technique in contrast to modified acid fast stain. Materials and Methods: A descriptive observational study was conducted at Nizam’s Institute of Medical Sciences, Hyderabad, India, over a period of three months (i.e., from July to September 2019). A total of 100 stool samples received by the Department of Microbiology were subjected to macroscopic and microscopic examination by saline mount, iodine mount, kinyoun acid fast stain, modified AR staining. Results: In the present study the prevalence of coccidian infections were observed to be 6%. Coccidian parasites reported were Cryptosporidium species and Cystoisospora species immunocompromised patients were found to be more prone to infections with coccidian parasites. The AR stain showed 100% agreement with modified acid fast stain. Conclusion: This study concluded that the AR stain is a rapid and better stain than kinyoun acid-fast stain for the detection of coccidian parasites.
导读:近年来,已知引起机会性感染的肠道球虫寄生虫有所增加,通常与其他形式的社区获得性腹泻难以区分,这表明需要适当和快速的诊断技术来恢复和识别该生物体。目的:探讨与改良抗酸染色相比,Auramine Rhodamine (AR)染色是否为一种灵敏、省时的染色技术。材料和方法:在印度海得拉巴尼扎姆医学科学研究所进行了一项描述性观察研究,为期三个月(即2019年7月至9月)。对微生物科收到的100份粪便标本,采用生理盐水垫、碘垫、金扬耐酸染色、改良AR染色等方法进行宏观和微观检查。结果:本研究球虫感染率为6%。报告的球虫寄生虫有隐孢子虫和囊异孢子虫,免疫功能低下的患者更容易感染球虫寄生虫。AR染色与改良抗酸染色100%一致。结论:AR染色法是一种快速且优于kinyoun抗酸染色法的球虫寄生虫检测方法。
