Introduction: Breast cancer is the commonest malignancy worldwide in women. Preoperative evaluation of breast lump plays a major role in the early diagnosis and management of the breast lesions. This study helps in subgrouping the breast lesions into various categories and provides the line of management of each category accordingly. Aim: To evaluate the cytomorphology of various breast lesions, to compare with histopathological findings and to assess the usefulness of Modified Masood’s Scoring Index (MMSI) in palpable breast lumps. Materials and Methods: This was a cross-sectional study done in 61 female patients presented with palpable breast lump between March 2019 and February 2021 at Pathology Department, Sri Venkateshwaraa Medical College Hospital and Research Centre, Puducherry, India. Cytological examination along with MMSI was applied on Fine Needle Aspiration Cytology (FNAC) aspirates, followed by histological confirmation. Under MMSI, the breast lesions were categorised into four groups: Non Proliferative Breast Disease (Non PBD), PBD without atypia, PBD with atypia and carcinoma breast. The data were collected and complied in Microsoft excel programme, appropriate graphs were made and percentages were calculated. Results: Total of 61 cases were analysed, females with age range of 23 to 64 years, mean age of 38 years. Majority of the cases presented with unilateral breast lump (92.5%). In MMSI Scoring, 15/61 (24.5%) were found with the score of 6 followed by 12/61 (19.6%) score of 8 which falls under NPBD. Total of cases 2/61 (3.2%) score of 24 while 3/61 (4.9%) with the score of 23 fell under Carcinoma breast category. Overall concordance observed between MMSI and histopathology was 59/61 cases which is 96.72%, which indicates the high degree of concordance with histopathological diagnosis. Conclusion: MMSI is a simple and reliable scoring system and can be applied on FNAC aspirates. MMSI increase the diagnostic accuracy and provide better concordance with histopathology.
乳腺癌是世界范围内女性最常见的恶性肿瘤。乳腺肿块的术前评估对乳腺病变的早期诊断和处理起着重要的作用。这项研究有助于将乳腺病变亚分组为不同的类别,并提供相应的管理路线。目的:评价各种乳腺病变的细胞形态学,与组织病理学结果进行比较,并评价改良马苏德评分指数(MMSI)在可触及乳腺肿块中的应用价值。材料和方法:这是一项横断面研究,对2019年3月至2021年2月在印度普杜切里Sri Venkateshwaraa医学院医院和研究中心病理科出现可触及乳房肿块的61名女性患者进行了研究。细胞学检查和MMSI应用于细针穿刺细胞学(FNAC)抽吸,然后进行组织学确认。MMSI将乳腺病变分为四组:非增殖性乳腺疾病(Non - prolifative breast Disease, Non - PBD)、无异型性的PBD、有异型性的PBD和乳腺癌。数据收集并在Microsoft excel程序中进行整理,绘制相应的图表,计算百分比。结果:共分析61例,女性年龄23 ~ 64岁,平均年龄38岁。大多数病例表现为单侧乳房肿块(92.5%)。MMSI评分中,15/61(24.5%)为6分,12/61(19.6%)为8分,属于NPBD。2/61例(3.2%)评分为24分,3/61例(4.9%)评分为23分。MMSI与组织病理学的总体符合率为59/61例(96.72%),与组织病理学诊断的符合率较高。结论:MMSI是一种简单可靠的评分系统,可用于FNAC吸痰器。MMSI增加了诊断的准确性,并提供了更好的一致性与组织病理学。

Introduction: Adiponectin is the most abundant adipocytokines secreted from adipose tissues and circulates in considerably high concentration in human plasma. Circulating adiponectin levels are decreased in obese subjects and this decrease has been thought to play a crucial role in the early development of atherosclerosis and cardiovascular diseases. Changes in adiponectin concentration has been reported in dyslipidemic subjects, but the evidence is controversial and no study conducted in north Indian population. Moreover, low molecular adiponectin seems to be linked with a worse lipid profile leading to dyslipidaemic through an association with triglyceride but the exact role of adiponectin in modulating lipid fraction is not well established. Aim: To correlate the level of serum adiponectin with lipid fractions in dyslipidemic male subjects and also to compare them with apparently healthy individuals. Materials and Methods: This case control study was conducted from April 2015 to November 2016 in the Biochemistry department of Rajshree Medical Research institute, Bareilly, Uttar Pradesh, India. A total of 70 non diabetic dyslipidemic male subjects between the age group 35 years to 55 years were selected and all the biochemical parameters (adiponectin, fasting plasma glucose, lipid profile) were evaluated and compared with 70 apparently healthy controls. Statistical analysis was performed by licensed version of Statistical Package for Social Sciences (SPSS) 16.0 software. All the data were expressed in “mean±SD”. Student ‘t’ test was also applied to see statistical significance in adiponectin levels between dyslipidemic subjects and healthy controls. Results: The study shows mean±SD of age in dyslipidemic group was 43.61±4.85 years and for control group was 43.53±5.53 years. The mean±SD of BMI in dyslipidemic group 25.72±2.43 was significantly higher than control group 23.42±1.56 with p-value <0.0001. The serum adiponectin concentration was significantly reduced in dyslipidemic subjects 5.11±2.04 μg/mL as compared to healthy control 6.79±1.37 μg/mL with p-value <0.0001. Serum total cholesterol, triglyceride and Low Density Lipoprotein (LDL)- cholesterol were found to be negatively correlated with serum adiponectin (r= -0.89, -0.76 and -0.74) and positively correlated with High Density Lipoprotein (HDL)-cholesterol (r= 0.70). Conclusion: The present study revealed that hypoadiponectinemia is associated with dyslipidaemic in men. The main observation of our present study, however, is that in dyslipidemic subjects, lower levels of adiponectin were associated with high total cholesterol, triglyceride, LDL-cholesterol and reduced HDL cholesterol, though more extensive, multicentric, prospective research with increase sample size could obtain wider insights.
脂联素是由脂肪组织分泌的最丰富的脂肪细胞因子,在人血浆中以相当高的浓度循环。肥胖受试者的循环脂联素水平下降,这种下降被认为在动脉粥样硬化和心血管疾病的早期发展中起着至关重要的作用。脂联素浓度的变化在血脂异常的受试者中有报道,但证据是有争议的,没有在北印度人群中进行研究。此外,低分子脂联素似乎通过与甘油三酯的关联而与较差的脂质特征相关,从而导致血脂异常,但脂联素在调节脂质部分中的确切作用尚未得到很好的确定。目的:探讨血脂异常男性受试者血清脂联素水平与脂质组分的关系,并将其与表面健康个体进行比较。材料与方法:病例对照研究于2015年4月至2016年11月在印度北方邦巴雷利Rajshree医学研究所生物化学系进行。选取年龄在35 ~ 55岁之间的非糖尿病性血脂异常男性受试者70例,评价其各项生化指标(脂联素、空腹血糖、血脂),并与70例表面健康对照进行比较。统计分析采用社会科学统计软件包(SPSS) 16.0许可版软件进行。所有数据均以“mean±SD”表示。采用学生t检验,观察血脂异常受试者与健康对照组之间脂联素水平的差异有统计学意义。结果:血脂异常组的平均±SD年龄为43.61±4.85岁,对照组为43.53±5.53岁。血脂异常组BMI均值±SD(25.72±2.43)显著高于对照组(23.42±1.56),p值<0.0001。血脂异常组血清脂联素浓度(5.11±2.04 μg/mL)显著低于健康对照组(6.79±1.37 μg/mL), p值<0.0001。血清总胆固醇、甘油三酯和低密度脂蛋白-胆固醇与血清脂联素呈负相关(r= -0.89、-0.76和-0.74),与高密度脂蛋白-胆固醇呈正相关(r= 0.70)。结论:本研究揭示了低脂联素血症与男性血脂异常有关。然而,我们目前研究的主要观察结果是,在血脂异常的受试者中,低水平的脂联素与高总胆固醇、甘油三酯、低密度脂蛋白胆固醇和低密度脂蛋白胆固醇相关,尽管更广泛、多中心、增加样本量的前瞻性研究可以获得更广泛的见解。

Introduction: Conventional Pap Smear (CPS) technique has been the mainstay for early detection of cervical cancer. However, its extensive use has not been possible due to the limitations, like presence of obscuring blood and inflammation, reducing its sensitivity markedly. False negativity of CPS is also very high so Liquid Based Cytology (LBC) was introduced. Aim: To compare cytomorphological patterns, diagnostic utility and adequacy of smears of cervical lesions on CPS and LBC. Materials and Methods: This study was a Prospective descriptive study, conducted in Department of Pathology of Dr. B R Ambedkar Medical College and Hospital, Bangalore for 19 months during November 2018 to May 2020 on 250 cases. The samples were taken with cervix-brush. First, a CPS was prepared and was immediately alcohol-fixed. After that same brush head was rinsed in LBC vial containing methanol. Statistical analysis was done using Statistical Package for Social Sciences 22.0 (SPSS) and R environment 3.2.2 for data analysis. Results: Most of the patients were in the fourth decade of life and 160 cases (64%) presented as white discharge per vaginum. Total 231 (92.4%) smears were satisfactory on CPS and 233 (93.2%) smears on LBC. The number of Low grade Squamous Intraepithelial Lesions (LSIL) increased from 4 cases (1.6%) in CPS to 6 cases (2.4%) in LBC in this study. Rate of detection of High grade Squamous Intraepithelial Lesion (HSIL) was more with LBC (11 cases, 4.4%) compared to that of CPS (7 cases, 2.8%). It was seen that in this study, sensitivity and specificity of LBC is better than CP in detecting LSIL and HSIL, but except specificity of CP was more than LBC in detecting LSIL. Present study showed overall sensitivity of 77.1% in CP and 94.3% in LBC and specificity of 97.2% and 100% in CP and LBC, respectively. The p-value calculated was <0.001 which was highly significant. Conclusion: The LBC technique showed clear background, well preserved cytomorphological details, removal of extra mucus, blood and inflammatory cell infiltrate as compared to CPS technique. Atypical cells or abnormal cells were seen better and were detected more by LBC as compared to CPS.
简介:传统的子宫颈抹片检查(CPS)技术一直是宫颈癌早期检测的主要手段。然而,由于存在模糊血液和炎症等限制,其敏感性显着降低,因此不可能广泛使用。CPS的假阴性也很高,因此引入了液体细胞学(LBC)。目的:比较宫颈CPS和LBC涂片的细胞形态、诊断价值和充分性。材料和方法:本研究是一项前瞻性描述性研究,于2018年11月至2020年5月在班加罗尔Dr. B R Ambedkar医学院和医院病理科进行,为期19个月,涉及250例病例。用宫颈刷采集样本。首先,准备一个CPS,并立即酒精固定。同样的刷头在含甲醇的LBC小瓶中冲洗。统计分析采用SPSS统计软件包(Statistical Package for Social Sciences 22.0)和R环境3.2.2进行数据分析。结果:大多数患者年龄在40岁左右,160例(64%)表现为阴道白色分泌物。CPS共231例(92.4%)满意,LBC共233例(93.2%)满意。在本研究中,低级别鳞状上皮内病变(LSIL)的数量从CPS的4例(1.6%)增加到LBC的6例(2.4%)。LBC的高级别鳞状上皮内病变(HSIL)检出率(11例,4.4%)高于CPS(7例,2.8%)。本研究发现,LBC检测LSIL和HSIL的敏感性和特异性均优于CP,但除了CP检测LSIL的特异性高于LBC。本研究显示,CP和LBC的总敏感性分别为77.1%和94.3%,CP和LBC的特异性分别为97.2%和100%。计算的p值<0.001,具有高度显著性。结论:与CPS技术相比,LBC技术背景清晰,细胞形态学细节保存完好,可去除多余的粘液、血液和炎症细胞浸润。与CPS相比,LBC能更好地观察和检测到非典型细胞或异常细胞。

Introduction: Group B Streptococcus (GBS) is the leading cause of neonatal sepsis all over the world. Maternal colonisation of GBS in vaginal and anorectal area poses risk for subsequent invasive disease. The prevalence of maternal colonisation varies with geographical, biological and socio-economical factors. Current recommendations consider maternal screening and antibiotic therapy to prevent GBS neonatal disease with a potential of alteration of infant gut flora. Aim: To find out the prevalence, outcome and antimicrobial susceptibility pattern of the GBS colonisation in antenatal women. Materials and Methods: A hospital-based descriptive crosssectional study was conducted in Government Medical College, Kozhikode, Kerala, India, during December 2017 to May 2019 including 300 antenatal women of 35-37 weeks gestational age. Vaginal and rectal swabs were taken and were subjected to microbiological examination and culture. Data analysis was done by Statistical Package for the Social Sciences (SPSS) version 16.0. The Chi-square test and Fisher’s exact test were used wherever applicable and p-value <0.05 is considered significant. Results: Among the 300 antenatal women, 8 (2.7%) were colonised with GBS. Higher rate of colonisation was observed in women of 21-25 years, higher parity, rural dwelling and in women with poor glycaemic control. All the colonised women received antibiotic prophylaxis with intravenous ampicillin. None of the colonised women or the neonates born to them developed any invasive GBS infection. Antibiotic susceptibility testing showed that all the isolates were sensitive to penicillin, ampicillin and vancomycin but only 62.5% of the isolates were susceptible to clindamycin and 37.5% of the isolates were susceptible to erythromycin. Conclusion: The prevalence of GBS colonisation is low in Asian countries, compared to the data from western countries. Evidence based usage of narrow spectrum antibiotics should be considered. Further studies regarding prevalence, antibiotic susceptibility pattern, cost benefit analysis of the antibiotic usage and its effect on neonatal gut flora etc, including a wider population, is a need of the hour in the setting of emergence of resistance.
B群链球菌(GBS)是全世界新生儿败血症的主要原因。GBS在阴道和肛肠区的母体定植可能导致随后的侵袭性疾病。产妇殖民化的普遍程度因地理、生物和社会经济因素而异。目前的建议考虑产妇筛查和抗生素治疗,以预防GBS新生儿疾病与潜在的婴儿肠道菌群的改变。目的:了解产前妇女GBS定植的流行情况、转归及药敏模式。材料与方法:2017年12月至2019年5月,在印度喀拉拉邦Kozhikode政府医学院进行了一项以医院为基础的描述性横断面研究,包括300名35-37周孕龄的产前妇女。取阴道和直肠拭子,进行微生物检查和培养。数据分析采用社会科学统计软件包(SPSS) 16.0版本。采用卡方检验和Fisher精确检验,p值<0.05为显著性。结果:300例产前妇女中,8例(2.7%)感染GBS。在21-25岁、胎次较高、农村居住和血糖控制较差的妇女中观察到较高的殖民化率。所有定植的妇女都接受静脉注射氨苄西林的抗生素预防。被感染的妇女和她们所生的新生儿都没有出现任何侵袭性GBS感染。药敏试验结果显示,所有菌株对青霉素、氨苄西林和万古霉素均敏感,但对克林霉素和红霉素的敏感性分别为62.5%和37.5%。结论:与西方国家的数据相比,GBS定殖在亚洲国家的流行率较低。应考虑以证据为基础使用窄谱抗生素。在出现耐药性的背景下,需要进一步研究患病率、抗生素敏感性模式、抗生素使用的成本效益分析及其对新生儿肠道菌群的影响等,包括更广泛的人群。

Introduction: Coronavirus Disease-2019 (COVID-19) infection can cause a wide range of symptoms, from asymptomatic infection and mild upper respiratory tract disease to severe viral pneumonia with respiratory failure and multiorgan malfunction. Through this study, effort was put forward to know the COVID-19 in terms of clinical characteristics, risk factors and laboratory parameters which in turn may serve as predictors of severe sickness and negative outcomes of COVID-19. Aim: To study the clinical characteristics, risk factors and laboratory parameters of COVID-19 patients in a part of North Eastern India, and also to compare these parameters between survivors and non survivors. Materials and Methods: This retrospective study was conducted in Silchar Medical College and Hospital, Silchar, Assam, India. Study included all patients of COVID-19 diagnosed by Reverse Transcriptase Polymerase Chain Reaction (RTPCR) or Rapid Antigen Test (RAT) admitted from 1st July, 2020 to 31st December, 2020. The data included demographic parameters, presenting symptoms, significant medical, surgical or drug history etc., and laboratory parameters including complete blood count, Random Blood Sugar (RBS), chest x-ray, renal and liver function test, C-reactive protein, Lactate Dehydrogenase (LDH), serum ferritin, troponin I etc. Data were statistically analysed by unpaired t-test for continuous variables and chi-square test was used for comparing proportions. Results: Out of a total 2262 study subjects, 2066 (91.34%) were discharged from the hospital after recovery and 196 (8.66%) had expired. The various parameters contributing significantly to mortality were male gender, age >60 years, various co-morbid conditions like diabetes mellitus, hypertension and cardiac illness. The laboratory parameters observed to be significantly associated with mortality were thrombocytopenia, leucocytosis, hyperglycaemia, raised value of lactate dehydrogenase, creatinine, D-dimer, ferritin, C-reactive protein. Radiological findings including ground glass opacities and pleural effusion also were more common in the non survivor group as compared to the survivor group. Conclusion: More than half of the deceased patients were older than 60 years of age. The prevalence of co-morbidities and mean level of laboratory parameters were significantly high among non survivors as compared to those who recovered.

Pyoderma Gangrenosum (PG) is a rare, ulcerative, non infectious neutrophilic inflammatory dermatosis and often associated with underlying systemic disorder. The incidence of PG is estimated to be 0.63 per 1,00,000 with the median age at presentation of 59 years. Among its clinical variants, classical PG is the most common. The diagnosis of PG can be difficult. This case series was an attempt to review the new trends for the diagnosis of PG and also to compare them with previous diagnostic criteria. Previously histopathological criteria were included as minor criteria in Su WP et al., classification. More recently proposed diagnostic criteria by Maverkis E et al., include histopathology of skin biopsy from edge of ulcer showing neutrophilic infiltration as a major criteria. Aim of the study is to correlate and stamp the clinically suspected cases of PG with help of histopathology. This retrospective observational case series study was conducted in a tertiary care hospital from May 2018 to April 2020 consisting of 19 cases (15 years to 68 years of age range; 13 males and 6 females). Detailed history, clinical examination and blood investigations were done in all suspected cases of PG followed by histopathological examination of skin biopsy. In 17 cases, lesions were located in lower limb, one case each in buttocks and lower abdomen. The classical, ulcerative form found in 12 cases (63.15%), vegetative form in 3 cases (15.78%), plaque and bullae form were in 2 cases each (10.52%). Pathergy test was positive in 11 cases (57.89%). Histopathological examination showed neutrophilic infiltration in all 19 cases (100%), vasculitis in 11 patients (57.89%), lymphoplasmacytic infiltrate in 6 patients (31.57%), pseudoepitheliomatous hyperplasia in 5 patients (26.31%), mixed inflammatory infiltrate in 4 patients (21%), Epidermal ulceration in 4 patients (21%) and mitosis is seen in 3 patients (15.78%). Histopathology is considered as a main tool which helps clinicians to stamp suspected cases of PG.
坏疽性脓皮病(PG)是一种罕见的溃疡性、非感染性中性粒细胞性炎症性皮肤病,常伴有潜在的全身性疾病。PG的发病率估计为0.63 / 100,000,发病时的中位年龄为59岁。在其临床变异中,经典PG最为常见。PG的诊断可能很困难。本病例系列旨在回顾PG诊断的新趋势,并将其与以前的诊断标准进行比较。以前的组织病理学标准在Su WP等人的分类中被作为次要标准。Maverkis等人最近提出的诊断标准包括溃疡边缘皮肤活检的组织病理学显示中性粒细胞浸润作为主要标准。本研究的目的是在组织病理学的帮助下对临床疑似PG病例进行关联和标记。本回顾性观察性病例系列研究于2018年5月至2020年4月在一家三级医院进行,包括19例病例(15岁至68岁;13名男性和6名女性)。所有疑似PG病例均行详细病史、临床检查和血液调查,并行皮肤活检组织病理学检查。17例病变位于下肢,臀部和下腹各1例。典型溃疡型12例(63.15%),营养型3例(15.78%),斑块型和大疱型各2例(10.52%)。病理检查阳性11例(57.89%)。19例组织病理检查均见中性粒细胞浸润(100%),血管炎11例(57.89%),淋巴浆细胞浸润6例(31.57%),假上皮瘤性增生5例(26.31%),混合性炎症浸润4例(21%),表皮溃疡4例(21%),有丝分裂3例(15.78%)。组织病理学被认为是帮助临床医生盖章疑似PG病例的主要工具。

Introduction: Fine Needle Aspiration Cytology (FNAC) is an important diagnostic tool for salivary lesions, which has decreased the number of unnecessary invasive surgeries for benign conditions. But, cytopathology of salivary lesions is complex presenting with similarity in cytological features albeit with histological heterogeneity. The novel Milan’s System for Reporting Salivary Gland Cytopathology (MSRSGC) is a six tiered classification, providing standard reporting terminology for salivary gland lesions in fine needle aspirates. Aim: To categorise the salivary lesions cytologically based on MSRSGC and to assess its utility in simplification of routine diagnosis of salivary gland lesions. Materials and Methods: A retroprospective study was conducted in a tertiary care centre over a period of five years from 2017 to 2021. All patients suspected to have salivary gland lesions were subjected to FNAC in the Department of Cytology. The cases were reported according to the MSRSGC criteria and assigned one of the categories. The statistical analysis was performed using Microsoft excel software, for calculation of descriptive statistical parameters such as measures of central tendency viz., mean, median, mode, percentage, range and ratio. Results: A sample size of 82 patients with salivary gland lesions was studied. Parotid gland was most commonly involved, among others. Most of the lesions were classified as category 4a (Neoplasm benign) (39%) and category 2 (Non neoplastic) (36.6%). Non Diagnostic (ND) constituted only 2.43% while malignancies constituted 4.9%. Ambiguous categories like Salivary gland neoplasm of Uncertain Malignant Potential (SUMP) and suspicious of malignancy constituted 13.4% and 3.6%, respectively. Conclusion: The introduction of MSRSGC has to a large extent standardised the reporting patterns, thereby assisting the clinicians to render improved patient care. The present study in comparison with other studies conducted worldwide, recommends the usage of MSRSGC for routine reporting.
细针吸细胞学(FNAC)是一种重要的唾液病变诊断工具,它减少了良性疾病不必要的侵入性手术的数量。但是,唾液腺病变的细胞病理学是复杂的,尽管存在组织学异质性,但在细胞学特征上具有相似性。新颖的米兰唾液腺细胞病理学报告系统(MSRSGC)是一个六层分类,提供了细针抽吸中唾液腺病变的标准报告术语。目的:基于MSRSGC对唾液腺病变进行细胞学分类,并评价其在简化唾液腺病变常规诊断中的应用价值。材料和方法:在2017年至2021年的五年间,在一家三级保健中心进行了一项回顾性研究。所有怀疑有唾液腺病变的患者都在细胞学部接受了FNAC检查。根据MSRSGC标准报告病例,并分配一个类别。统计分析使用Microsoft excel软件进行,用于计算描述性统计参数,如集中趋势的度量,即平均值,中位数,模式,百分比,范围和比率。结果:对82例涎腺病变患者进行了研究。腮腺是最常见的受累部位。大多数病变分为4a类(肿瘤良性)(39%)和2类(非肿瘤性)(36.6%)。非诊断性(ND)仅占2.43%,恶性肿瘤占4.9%。不确定恶性潜能涎腺肿瘤(SUMP)和可疑恶性肿瘤等模糊类别分别占13.4%和3.6%。结论:MSRSGC的引入在很大程度上规范了报告模式,从而帮助临床医生提供更好的患者护理。本研究与世界范围内进行的其他研究比较,建议使用MSRSGC作为常规报告。

Introduction: The Emergency Departments (ED) are equipped with Point-of-Care (POC) blood gas analysers (BGA) which deliver fast results on multiple parameters of arterial/venous blood. There is no consensus among ED physicians on the reliability of electrolyte results by POC Arterial Blood Gas (ABG) analysis compared to venous serum electrolyte from Central Laboratory Analyser/Auto-Analyser (CLA/AA). Aim: To compare the electrolyte(sodium and potassium) by POC arterial BGA (ABL800 Flex Radiometer) with venous electrolyte by CLA (Beckman Coulter AU 5800). Materials and Methods: This cross-sectional study was performed in the ED and Central Laboratory of the tertiary hospital from 1st July 2018 to 31st July 2019. A total of 254 critically ill adult patients with various etiologies, were enrolled in the study. The arterial and venous blood samples were collected for electrolyte measurement within a span of 15 minutes. The ABG samples, anticoagulated with liquid heparin, were processed in POC BGA. The venous samples collected in plain tubes were analysed in CLA. The results of sodium and potassium were compared by the mean, correlation coefficient, p-value, and Bland Altman Plots {95% Limit of agreement (LOA)}. Results: Out of 254 paired samples (mean age: 63±15 years), 157 (61.8%) were males and 97 (38.2%) females. The mean sodium values were 131.9±7.7 mmol/L in ABG and 132.3±7.1 mmol/L in CLA (p-value <0.0001). The mean difference was 0.4 mmol/L. The mean potassium values were 3.9±1.0 mmol/L (ABG) and 4.2±0.9 mmol/L (CLA), {p-value<0.0001}. The mean difference was 0.3 mmol/L. These differences were within the accepted range specified by the United States Clinical Laboratory Improvement Amendments. There were statistically significant strong positive correlations between the measurements of the two instruments r=0.78 for sodium and r=0.76 for potassium. The 95% LOA for sodium and potassium on both the instruments were -10.03 to 9.09 mmol/L and -1.49 to 0.97 mmol/L respectively, both wide and unacceptable. Conclusion: The arterial sodium and potassium measurements by BGA were not reliable in decision making in ED when compared to the venous serum by CLA as the 95% LOA was wide and unacceptable. Hence, sodium and potassium values by BGA alone might not be used as criteria for management without confirmation from venous serum values by CLA.
简介:急诊科(ED)配备了即时护理(POC)血气分析仪(BGA),可快速提供动脉/静脉血的多个参数结果。与中央实验室分析仪/自动分析仪(CLA/AA)的静脉血清电解质相比,POC动脉血气(ABG)分析电解质结果的可靠性在急诊科医生中没有达成共识。目的:比较POC动脉BGA (ABL800 Flex辐射计)和CLA (Beckman Coulter AU 5800)测定的静脉电解质(钠、钾)。材料与方法:本横断面研究于2018年7月1日至2019年7月31日在三级医院急诊科和中心实验室进行。共有254名不同病因的危重成人患者参加了这项研究。15分钟内取动、静脉血测定电解质。用液体肝素抗凝的ABG样品在POC BGA中处理。用CLA法分析平管采集的静脉标本。采用均数、相关系数、p值和Bland Altman图{95%一致限(LOA)}比较钠和钾的结果。结果:254例配对样本(平均年龄63±15岁)中,男性157例(61.8%),女性97例(38.2%)。ABG和CLA的平均钠值分别为131.9±7.7 mmol/L和132.3±7.1 mmol/L (p值<0.0001)。平均差异为0.4 mmol/L。平均钾值分别为3.9±1.0 mmol/L (ABG)和4.2±0.9 mmol/L (CLA), p值<0.0001}。平均差异为0.3 mmol/L。这些差异在美国临床实验室改进修正案规定的可接受范围内。两种仪器的测量值之间存在统计学上显著的强正相关,钠的测量值r=0.78,钾的测量值r=0.76。两种仪器对钠和钾的95% LOA分别为-10.03 ~ 9.09 mmol/L和-1.49 ~ 0.97 mmol/L,范围较广且不可接受。结论:与CLA相比,BGA测定的动脉钠、钾在ED诊断中不可靠,95% LOA过大且不可接受。因此,如果没有CLA的静脉血清值的确认,仅BGA的钠和钾值可能不能作为治疗的标准。

Introduction: The irrational and inappropriate use of beta lactam antimicrobial drugs has led to the advent of Extended Spectrum Beta-Lactamase (ESBL) resistant strains. ESBL producing Enterobacteriaceae strains are frequent causative agents both in community and in acquired nosocomial infections and Urinary Tract Infections (UTI). The phenotypic confirmatory tests rarely identify all ESBLs. Chrom ID (Chromogenic identification Media) ESBL – Bx (bioMerieux) is a completely new and innovative chromogenic medium designed specifically for the screening of ESBL producing Enterobacteria directly from urine samples. It is a ready to use selective media which is sensitive and specific for rapid and presumptive identification of ESBL producing Enterobacteriaceae. Aim: Early detection of ESBL producing Enterobacteriaceae directly from urine samples on chromogenic medium (Chrom ID- ESBL- Bx) and confirmation of ESBL producing Enterobacteria using Disc Potentiation Test (DPT). Materials and Methods: The present cross-sectional study was conducted in the Department of Microbiology, Rangaraya Medical College, Kakinada, Andhra Pradesh, India from November 2019 to March 2020 (five months duration). The study was done on 70 urine samples from patients with UTI. All samples were subjected to wet mount, inoculated directly for culture on Chrom ID ESBL- Bx agar and MacConkey agar. Antibiotic Susceptibility testing of ceftazidime and cefotaxime was done by Kirby-Bauer disc diffusion method and conformation of ESBL production by DPT using Clinical and Laboratory Standards Institute (CLSI) method. The Statistical Package for the Social Sciences (SPSS) Statistical package version (18.0) was used. Results: A total of 56 (80%) isolates were obtained from 70 urine samples, out of them 28 (50%) were Escherichia coli, 21 (37.5%) were Klebsiella spp., 7 (12.5%) were Proteus spp., 23 (82.14%) isolates of Escherichia coli, 15 (71.43%) of Klebsiella spp., 6 (85.71%) of Proteus spp., isolated were screened positive using Chrom ID ESBL-Bx agar. About 44 (78.57%) of total Enterobacteria (56) were screened for ESBL production. 20 (86.96%) of Escherichia coli, 11 (73.33%) of Klebsiella spp., and 5 (83.33%) of Proteus spp., that were screened positive using Chrom ID ESBL agar were confirmed (by DPT) as ESBL producers and 2 (16.6%) of total (12) isolates that were screened negative by Chrom ID ESBL agar were confirmed as ESBL producers when screened and confirmed by DPT. So sensitivity and specificity CHRO Magar was 94.73% and 55.5%. Conclusion: ESBL continues to become a serious public health threat. Results from present study showed that CHROMagar ESBL has a high sensitivity and a convenient method for making provisional diagnosis of drug resistant Enterobacterial infections in 24 hours. Chrom ID ESBL- Bx agar medium allows easy differentiation of different bacteria based on colony colouration.
引言:β -内酰胺类抗菌药物的不合理和不适当使用导致了扩展谱β -内酰胺酶(ESBL)耐药菌株的出现。产生ESBL的肠杆菌科菌株是社区和获得性医院感染和尿路感染(UTI)的常见病原体。表型确认试验很少能识别所有esbl。Chrom ID(显色鉴定培养基)ESBL - Bx (bioMerieux)是一种全新的创新显色培养基,专为直接从尿液样本中筛选产生ESBL肠杆菌而设计。它是一种敏感和特异的选择性培养基,可用于快速和推定鉴定产生ESBL的肠杆菌科。目的:用显色培养基(Chrom ID- ESBL- Bx)检测尿样中直接产肠杆菌科ESBL,并采用圆盘增强试验(DPT)确认ESBL产肠杆菌。材料与方法:本横断面研究于2019年11月至2020年3月在印度安得拉邦Kakinada市Rangaraya医学院微生物学系进行(为期5个月)。这项研究是对来自尿路感染患者的70份尿液样本进行的。所有样品均湿载,直接接种于Chrom ID ESBL- Bx琼脂和MacConkey琼脂上培养。采用Kirby-Bauer盘片扩散法对头孢他啶和头孢噻肟进行药敏试验,采用临床与实验室标准协会(CLSI)方法对DPT制备的ESBL进行构象检测。采用SPSS (Statistical Package for The Social Sciences)统计软件包18.0版本。结果:70份尿样共分离到56株(80%),其中大肠埃希菌28株(50%),克雷伯氏菌21株(37.5%),变形杆菌7株(12.5%),大肠埃希菌23株(82.14%),克雷伯氏菌15株(71.43%),变形杆菌6株(85.71%),用Chrom ID esblb - bx琼脂筛选阳性。在56株肠杆菌中筛选到44株(78.57%)产生ESBL。用Chrom ID ESBL琼脂筛选阳性的大肠埃希菌20株(86.96%)、克雷伯氏菌11株(73.33%)、变形杆菌5株(83.33%)被DPT证实为ESBL产生菌,经DPT筛选确认为阴性的12株中有2株(16.6%)为ESBL产生菌。因此,CHRO Magar的敏感性和特异性分别为94.73%和55.5%。结论:ESBL继续成为严重的公共卫生威胁。本研究结果表明,CHROMagar ESBL具有较高的敏感性,是一种方便的24小时耐药肠杆菌感染临时诊断方法。Chrom ID ESBL- Bx琼脂培养基可以根据菌落颜色轻松区分不同的细菌。

Introduction: Thyroid disorders are very common in females and are known to prevent ovulation. Thyroid disorders can impact menstrual cycles and causes menstrual irregularities and infertility in females. Aim: To determine effects of hypothyroidism on menstrual cycle pattern and prevalence of subfertility among women having thyroid dysfunction. Materials and Methods: This cross-sectional study was conducted in Department of Obstetrics and Gynaecology in collaboration with Department of Endocrinology in Government Medical College, Datia Madhya Pradesh, India from July 2019 to June 2021. A total of 205 patients aged 18-45 years were taken. Among them, 116 and 89 patients were of hypothyroid and euthyroid respectively. After properly selecting patients, detailed history of their menstrual cycles was taken and effect of thyroid dysfunction on menstrual irregularities was assessed. The collected data were evaluated and analyzed using Statistical Package of the Social Sciences (SPSS). Results: A total of 205 patients participated in present study. Mean age was 35+/-5 years. Among 205 subjects, 116 were hypothyroid and 89 were euthyroid. Among the hypothyroid subjects, 72 (62.1%) had normal menstrual cycles, 23 (19.8%) had history of oligomenorrhea, 12 (10.3%) had polymenorrhea, and 9 (7.7%) had amenorrhea, while among the thyroid subjects, 76 (85.4%) had normal menstrual cycle, 6 (6.7%) had oligomenorrhea, 5 (5.6%) had polymenorrhea, and 2 (2.2%) had amenorrhea, with statistically significant differences (p<0.001). The proportions of primary 13 (11.2%) and secondary 9 (7.7%) subfertility were significantly higher among hypothyroid subjects compared with thyroid subjects (p<0.05). The prevalence of subfertility was 7 (7.8%), 10 (14.28%), and 12 (26.08%) among the thyroid, overtly hypothyroid, and subclinical hypothyroid subjects, respectively. Conclusion: In this study, effects of thyroid dysfunction were presumably significant on menstrual cycle pattern and fertility; therefore, thyroid status should be assessed in all patients with menstrual disorders and appropriate treatment should be initiated early.
简介:甲状腺疾病在女性中非常常见,并且已知会阻止排卵。甲状腺疾病会影响月经周期,导致女性月经不规律和不孕。目的:探讨甲状腺功能减退症对甲状腺功能障碍妇女月经周期模式和低生育能力的影响。材料与方法:本横断面研究于2019年7月至2021年6月在印度Datia Madhya Pradesh政府医学院妇产科与内分泌科合作进行。共选取205例患者,年龄18-45岁。其中甲状腺功能减退116例,甲状腺功能正常89例。在适当选择患者后,详细记录其月经周期,并评估甲状腺功能障碍对月经不规律的影响。使用SPSS软件对收集到的数据进行评价和分析。结果:共有205例患者参与本研究。平均年龄35±5岁。205例受试者中,甲状腺功能减退116例,甲状腺功能正常89例。甲状腺功能减退者月经周期正常72例(62.1%),月经少史23例(19.8%),多经12例(10.3%),闭经9例(7.7%),而甲状腺功能减退者月经周期正常76例(85.4%),月经少史6例(6.7%),多经5例(5.6%),闭经2例(2.2%),差异有统计学意义(p<0.001)。甲状腺功能减退组初级13级(11.2%)和次级9级(7.7%)生育能力低下的比例显著高于甲状腺功能减退组(p<0.05)。甲状腺、明显甲状腺功能减退和亚临床甲状腺功能减退患者的低生育能力患病率分别为7(7.8%)、10(14.28%)和12(26.08%)。结论:在本研究中,甲状腺功能障碍可能对月经周期模式和生育能力有显著影响;因此,所有月经紊乱的患者都应评估甲状腺状态,并应及早开始适当的治疗。
