Histopathological Spectrum of Breast Carcinoma in a Tertiary Care Centre and its Association with ABO Blood Grouping and Rh Typing

Background: Globally, breast cancer contributes to 27.7% of the newly diagnosed cases of cancer among women. Early screening and timely diagnosis of the lesions of breast help in alleviating the anxiety among patients. Histopathology is the gold standard in diagnosing the lesions, assessing the adequacy of treatment, and in disease prognosis. Studies have shown that ABO blood type has been associated with risk and survival for several malignancies. However, data for an association with breast cancer are inconsistent. Aim: To study the histopathological spectrum breast carcinomas and to investigate the presence of a possible association between breast cancer in women and ABO blood group and Rh factor. Materials and Methods: This retrospective descriptive study was done for a period of 4 years on 110 mastectomy specimens histopathologically diagnosed as breast cancers, and clinico-pathological data collected and analysed with records from the Department of Pathology, Saveetha Medical College. Association of breast cancer with ABO blood grouping and Rh typing was studied. Results: Left breast was involved in most cases (96.4%). The mean age was 50.86 years, with 41-50 years age group showing peak incidence. Infiltrating breast carcinoma, no special type (89.6%) was the most common histological type. ER and PR positivity was seen in 46.4% and 41.8% of cases respectively. A statistically significant association was seen between hormone receptor status and histological grade. 39.1% cases belonged to O blood group, and Rh positivity was seen in 96.4% of the cases. No association was found between breast cancer and ABO/Rh blood grouping.

Association of ABO Blood Grouping and Periodontal Disease: A Literature Review

Although the correlation between the ABO blood group and certain systematic diseases is a well-documented fact. Few studies have explored the relationship of ABO with oral disorders including periodontal diseases (PD). This literature review aimed to assess the possible association between ABO blood grouping and PD. For this purpose, we searched online databases like PubMed and google scholar with the following terms in different combinations PD, ABO blood groups, gingivitis, the prevalence of periodontitis, aggressive periodontitis, risk factors of periodontitis, Association of PD and ABO, ABO Rh factor. English version papers describing the Oral health status are covered through research that includes clinical investigations, case studies, and retrospective studies on the subject. Historic reviews, articles with unpublished data, and letters to the editors were omitted from the survey following publications. The author thoroughly checked the titles and abstracts of the papers. The complete text was thoroughly assessed, and the relevant articles were analyzed in accordance with qualifying criteria. For further original and review research, references were further reviewed. Since our targeted subject was answered by a restricted number of original research. We identified fourteen articles describing the association of ABO blood types with PD. findings of our study concluded the genetic basis of the association of ABO blood types for the development of PD. six of the research provided here showed that the blood type O can serve as a prognostic factor for the development of PD. ABO blood types and Rhesus factors can be a risk predictors in the development of PD.

The Application of Virtual Simulated Experiment in the Theoretical Teaching (ABO Blood Grouping) for Physiology

Objective: To explore the effect on students’ independent learning capacity through the usage of virtual simulated experiment ((here after referred to as VSE) in the theoretical teaching for Physiology. Methods: This research is conducted in Inner Mongolia Medical University. Experimental group: students majored in Forensic Medicine, Class 1, 2019. Self-study teaching mode is applied in the content of blood type and ABO blood grouping with VSE in the theoretical course. Control group: students majored in Psychiatry, Class 1, 2019. Traditional teaching mode is applied to the same content. The effects of these two modes are assessed through test performance and questionnaire. Results: Students adopted self-study mode with VSE are superior to those employed traditional teaching mode in test performance. Questionnaires answered by experimental group show that students are satisfied with self-study mode through the application of VSE. Meanwhile, their independent learning capacity has been improved. Conclusion: The application of self-study teaching mode with VSE can enhance students’ learning effect and contribute to the improvement of self-study ability. It should be applied further in medical theory teaching.

Reliability of Postmortem ABO Blood Grouping: A Study of 100 Cases

Blood grouping has been one of the cornerstones for identification of biological materials in forensic investigations. Antigens of the ABO system can be detected even prior to birth. ABO blood groups can also be detected after death for a long period in many body tissues (teeth, bones, etc.). Blood has its own forensic value in many medico-legal issues. The present study looked at a total number of 100 autopsy cases brought for medico-legal investigations in the mortuary of the Department of Forensic Medicine in collaboration with the Department of Pathology at the Postgraduate Institute of Medical Sciences (PGIMS), Rohtak (Haryana, India). The blood samples were collected from right ventricle without any anticoagulant. ABO blood grouping was performed by direct haemagglutination technique using monoclonal antisera. Reverse blood grouping was also attempted. Our results showed that ABO blood group antigens can be detected from blood fluid after death, even in decomposed bodies with an estimated post-mortem interval (EPMI) of <85 hours. Our results also show that as post-mortem interval increases beyond a certain limit there is a decrease in antigens on RBCs in the post-mortem blood.

Serological and genotyping study of rare cis-AB01/O01 in the area of Inner Mongolia - with a case report

The antigen gene of ABO blood group system, called ABO, is located on human chromosome 9, with a total length of 19.5 kb. It is the first blood group system found by human beings.[1] ABO blood group subtypes are formed by ABO genovariation, i.e., gene A variation for A subtype, gene B variation for B subtype and gene O variation for new O alleles. ABO subtypes contain A3, Ax, Ael, Aw, Am, B3, Bx, Bel, Bw, cis-AB, B (A). Generally, an individual with AB blood group has an A allele on one chromosome, with B allele on its paired chromosome. This phenomenon is called trans-AB. However, cis-AB is a unique ABO phenotype that A and B alleles are located on the same chromosome, so that it can be inherited by the next generation.[2] This special mode of inheritance often causes a discrepancy of ABO blood grouping and then reduces the effectiveness and safety of blood transfusion.Therefore, to accurately identify the blood group of cis-AB is a precondition for the safety of blood transfusion.[3] The serological and genotyping analysis on a case of cis-AB patient in our hospital is reported as follows.
