Anaemia is not a diagnosis, but merely an objective sign of disease. The correct treatment requires an understanding of the pathogenesis of the condition. Aim: To identify disorders presenting as anaemia in paediatric population. Also to analyse the data by grading of anaemia and to calculate the proportion of anaemia in various paediatric age groups. Materials and Methods: This cross-sectional study was conducted at Government Medical College, Ernakulum, Kerala, India, from September 2017 to February 2018, on 211 paediatric patients of age groups from newborn upto 18 years. After a detailed clinical history and examination, Complete Blood Count (CBC), peripheral smear preparation, reticulocyte count, renal function tests, liver function tests, and if necessary, radiological and bone marrow examination were done. The mean haemoglobin in the categories were compared with Comprehensive National Nutritional Survey Data. The data obtained were entered in Microsoft excel 365 and further analysed. Categorical variables were analyzed by Fisher’s- exact test and continuous variables by Analysis of Variance (ANOVA) and Kruskal-Wallis test and the significance level was set at p-value ≤ 0.05. Results: Of the 211 patients, 120 (56.87%) were males and 91 (43.13%) were females. The average haemoglobin level varies across age groups and sex. In the case of newborns, average Hb was 9.31 g/dL in males and 10.4 g/dL in females. A total of 211 patients presented with 339 disease conditions, with respiratory disorders in 98, followed by 83 nutritional diseases, 49 infections and 35 systemic diseases. Total of 132 patients in age group of 6 months to 4 years, presented with maximum disorders (206). A total of 186 (54.8%) cases presented with Microcytic Hypochromic Anaemia (MHA), 149 (43.95%) with Normocytic Normochromic Anaemia (NNA) and only 4 (1.18%) with Haemolytic Anaemia (HA). No cases of macrocytic anaemia were noted. Conclusion: Total of 76.8% cases of MHA (42.1% of total anaemia cases) are associated with Nutritional, Respiratory and Infectious conditions which can be managed by public health measures. The haemoglobin levels in neonates and less than 6 months age group were significantly less than population mean which needs to be addressed. In similar manner, girls in school going age group had significantly lower Hb than boys.","PeriodicalId":31115,"journal":{"name":"National Journal of Laboratory Medicine","volume":"1 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2022-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"71271374","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}

Limited data is found on association between oxidant and antioxidant status and significance of oxidative stress index in patients with malarial infection and anaemia in south Indian population. Aim: To measure the levels of oxidants and antioxidants and oxidative stress index in patients with malaria and their association with anaemia. Materials and Methods: The present case-control study was conducted in Department of Biochemistry, Osmania General Hospital, Hyderabad, India. A total of 50 subjects of malaria aged 20-45 years were included as cases based on inclusion criteria and exclusion criteria. Control group comprised of 50 healthy age and gender matched subjects. Haemoglobin (Hb), serum Malondialdehyde (MDA), Superoxide Dismutase (SOD), Total Antioxidant Capacity (TAC) was estimated in both the groups by standard methods using Ultraviolet Spectrophotometer. Independent sample t-test was used to test for the difference in all biochemical parameters among study and control groups. The study of orrelation among the parameters was done by Pearson’s correlation. Results: Both the groups were age and gender matched (p=0.39). MDA was significantly elevated in cases as compared to controls (p<0.0001). SOD, Ferric Reducing Ability of Plasma (FRAP), Hb were significantly lower in cases as compared to controls with p-value <0.0001. In the present study, it was found that there was a significant negative correlation between Hb and oxidative stress index (MDA/FRAP=-0.480) with p-value=0.0001 in patients with malaria. Conclusion: The present study concluded that oxidative stress might be a cause of malarial anaemia. Alterations in oxidant and antioxidant levels might have a role in pathogenesis of malaria. As compared to individual markers, oxidative stress index was found to be significantly associated with malarial anaemia denoting its role as a better marker in these patients. Antimalarial therapy targeting the above factors might decrease the pathogenesis, morbidity and mortality in patients with malaria.","PeriodicalId":31115,"journal":{"name":"National Journal of Laboratory Medicine","volume":"1 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2022-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"71269648","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}

Deferral is a painful and sad experience both for the donor and the centre. Thus, every blood centre has to pivot between admissible quality and desired quantity. Aim: To find out incidence and pattern of donor deferral in a tertiary care hospital, Meerut, Uttar Pradesh, India. Materials and Methods: A retrospective cross-sectional study was conducted over a period of four years from January 2016 to December 2019 in a blood bank, Department of Pathology in a tertiary care hospital of Meerut, Uttar Pradesh, India. Details of donors who were deferred either temporarily or permanently during the study period were collected from the deferral files. Data analysis was done by calculating the percentage for every cause of donor deferral. Results: Out of the 29,663 donors who registered for blood donation during the study period, 2,626 donors were deferred due to several reasons. Temporary reasons (2592) were like anaemia, medications, alcohol, allergy, low-weight, fever, tattooing and permanent causes (34) were like hypertension, cardiac disorders, diabetes, asthma and thyroid disorders. Anaemia was the most common cause for deferral and total deferral rate came out to be 8.85%. Conclusion: Studying and analysing the profile of blood donors helps to identify categories of population which could be targeted to increase pool of voluntary blood donors. Education, motivation and treatment of these deferred donors due to anaemia or other temporary causes is an important aspect in blood banking, so that these donors may be recruited again.","PeriodicalId":31115,"journal":{"name":"National Journal of Laboratory Medicine","volume":"11 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2022-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"71270183","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}

TATE is defined as “eosinophilic stromal infiltration of a tumour not associated with tumour necrosis or ulceration”. The exact role of TATE in malignancies is yet unclear but studies have shown that TATE usually has a favourable outcome in head and neck Squamous Cell Carcinoma (SCC). Therefore, more studies are needed to substantiate this data. Aim: To compare TATE between normal epithelium and Oral Squamous Cell Carcinoma (OSCC) and compare TATE between the histological grades of OSCC. Materials and Methods: A retrospective study was conducted at Dr. BR Ambedkar Medical College, Bangalore, Karnataka, India, from June 2019-January 2021 which included 50 cases, 10 from normal mucosa and 40 histopathologically diagnosed cases of OSCC. 1% congo red solution was used to stain 4 μm thick sections. The sections were examined at a high magnification (40X) and 10 microscopic fields were examined in succession for eosinophils. The average number of eosinophils observed were compared using univariate analysis, which included the Analysis of Variance (ANOVA) test and the Chi- square test and a p-value of 0.001 was considered statistically significant. Results: The mean value of tissue eosinophils increased in OSCC compared to normal mucosa, according to present study findings. When comparing different grades of carcinoma, statistical analysis revealed that well differentiated squamous cell carcinoma had a greater TATE than other grades, which was statistically significant (p-value <0.001). Conclusion: The higher eosinophil count in well differentiated OSCC compared to the other grades could be associated with a better clinical outcome for the patient. In OSCC, TATE can be utilised as a predictor of a good prognosis.","PeriodicalId":31115,"journal":{"name":"National Journal of Laboratory Medicine","volume":"1 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2022-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"71270712","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}

The cell proliferation index may provide an objective method for assessing tumour biology. The Ki-67 is considered to be the most reliable proliferative marker predicting the tumour behaviour of various systemic and intracranial neoplasms. As it reflects tumour proliferating potential, it helps in determining the grade and hence the likelihood of recurrence. This study was carried out considering that very few studies of Ki-67 Labelling Index (LI) is seen in Central Nervous System (CNS) neoplasms collectively. Aim: To study the Ki-67 LI in CNS neoplasms and the association of Ki-67 LI with different parameters like age, sex, World Health Organisation (WHO) grading and histological types. Materials and Methods: The present descriptive analytical study was conducted at Department of Pathology, Mahadevappa Rampure Medical College, Karnataka, India, attached to a tertiary care hospital, Kalaburagi, for a period of five years between 1st Aug 2013 to 31st July 2018 after approval from the Institutional Ethics Committee. The formalin-fixed and paraffin-embedded tissue sections were stained with haematoxylin and eosin. Immunohistochemistry (IHC) was carried out with Ki-67 antibody using standard protocol. The data was analysed using IBM SPSS software version 19.0. The descriptive statistics frequency and percentages were calculated. The morphological grading of CNS tumours was done and the distribution of Ki-67 LI values were analysed. Results: A total of 102 histopathologically diagnosed primary CNS tumours were included in the study. High incidence of CNS neoplasms was seen in 3rd to 4th decade with slight male preponderance. This study included 40 meningioma cases. Mean percentages of Ki-67 LI for grade I and grade II meningiomas were 3.3% and 4%, respectively. The Ki-67 mean value for Astrocytomas grade I was 5.6% and grade II was 8.7%. Grade IV Glioblastoma and Gliosarcoma showed mean value of 18% and 18.8%, respectively. It was observed that LI increased with increase in grade of the tumour. Schwannoma and Dysembryoplastic Neuroepethelial Tumour (DNET) showed Ki-67 LI of 2.9% and 2.6%, respectively. Mean value of Ki-67 LI of other primary CNS neoplasms were as follows: Medulloblastoma 53%, Atypical Teratoid/Rhabdoid Tumour (ATRT) 32%, Haemangiopericytoma 8%, Neurocytoma 4%, Malignant Peripheral Nerve Sheath Tumour (MPNST) 3%, Ganglioglioma 4% and Haemangioblastoma 4%. Conclusion: The Ki-67 LI is the simplest and the most reliable method for evaluating the cell proliferation. It has a great value in designating the exact grade of the tumour when used in combination with histopathological features. It can also be used for planning of adjuvant therapy in primary CNS neoplasms.","PeriodicalId":31115,"journal":{"name":"National Journal of Laboratory Medicine","volume":"1 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2022-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"71270754","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}
