ABSTRACT
Normal concentration of WBCs in blood varies between 4000 and 11,000 per microliter and are classified intotwo variants namely granulocytes and agranulocytes on the basis of presence and absence of granules.Manual methods of calculation of TLC include- Neubauer chamber and estimating WBC on leishman stainedslides whereas automated methods are based on impedance or light scattering technology. The study comparedthe efficacy of both these methods in statistical terms using Chi Square test. 100 cases of leucocytosisanalyzed over a period of 1 year at MMIMSR, Mullana, Haryana revealed leucocytosis prevalent in 4-6 decadeof life with slight male predominance. The pearson coefficient for TLC came out to be p value =0.215 (notsignificant) but for DLC, calculations revealed p values for polymorphs, lymphocytes, eosinophils andmonocytes to be significant (p value =0.000 each). To conclude, standard manual methods should be advocatedas special practice where there is definite need of morphological and quantitative evaluation of WBCs and tovalidate the automated methods by which the laboratories can optimize patient care and not as a replacement
ABSTRACT
Anemia, reduced red cell mass below normal range, results in reduction of oxygen carrying capacity of bloodthat results in tissue hypoxia. MCV, MCH, MCH and RDW represent a sensitive indicator to study erythrocytemorphology. Mentzer Index recommended MI<13 to be suggestive of â-TT and MI>13 for Iron deficiencyanemia. 100 cases were analyzed prospectively over a span of 1 year at MMIMSR, Mullana. The studyrevealed 34% of patients to be in age group of 21-30 years with (59%) female predominance out of whichmajority of cases were of moderate anemia (73%). Erythrocyte indices revealed pattern with majority ofsamples having MCV, MCH and MCHC to be in normal range while RDW showed increased values. Mentzerindex came out to be >14 in 96% of samples. To conclude evaluation of erythrocyte indices and Mentzerindex aids in quatitative assessment of anemia and also to distinguish between iron deficiency anemia andthalassemia trait.
ABSTRACT
Rh system in today’s world is probably the most complex red cell antigen system in humans. The presence ofD antigen confers Rh positivity and vice versa. Two allelic antigen pairs, E/e and C/c are also found on the Rhprotein. The D antigen is the most immunogenic red cell antigen after A and B. As there is paucity of datadistribution of Rh antigen subgroup from the Indian literature, the study was conducted to know the prevalenceof Rh antigen subgroups in this part of the region and to determine the phenotype and most common genotypeof Rh antigen among the blood donors. The observational 1 year prospective study was conducted on blooddonors attending the blood bank in the Department of Pathology, MMIMSR, MMDU, Mullana.The studycomprised of blood donors of various age groups which included 90%(450) males and 10%(50) females. Anoverall Rh D positivity was seen in 88.4% of blood donors while 11.6% lacked the D antigen. The mostcommon Rh phenotype was ccDEE 26.6%. In conclusion, sensitization to clinically important blood groupantigens can be prevented through complete blood typing. All patients should be genotyped before the firstblood transfusion
ABSTRACT
The study included gastric endoscopic biopsies received in the department of pathology, MMIMSR,Mullana, Haryana. 130 gastric biopsies were included in the study. The most common presentingcomplaint was pain abdomen. The neoplastic lesions commonly presented as carcinoma whereas thenon-neoplastic lesions presented as inflammatory lesions on endoscopy. Non-neoplastic lesions werefound to be common out of which gastritis was the most common lesion. Associated conditions werefound to be H. Pylori and intestinal metaplasia with gastritis. Majority of the lesions were nonneoplastic, presenting with pain abdomen & inflammatory findings on endoscopy. The neoplasticlesions comprised of adenocarcinoma & signet ring cell carcinoma. 4 cases of signet ring cell carcinomawere noted. Percentage of concordance between endoscopic & histologic diagnoses was calculatedwherein cases of gastritis, ulcer, polyps & carcinoma showed 100%, 96.3%, 71.4% & 100%concordance respectively.The conclusion of the study was that histological examination in adjunct with endoscopy should beconsidered as much more valuable diagnostic tool rather than endoscopy alone.
ABSTRACT
The study included endoscopic duodenal biopsies received in the department of pathology, MMIMSR,Mullana, Haryana. 44 biopsies were included in the study. The most common presenting complaintwas pain abdomen followed by diarrhea. The neoplastic lesions commonly presented as carcinomawhereas the non-neoplastic lesions presented as inflammatory lesions on endoscopy. Non-neoplasticlesions were found to be common with villous atrophy predominating the list. Majority of the lesionswere non-neoplastic, presenting with pain abdomen & inflammatory findings on endoscopy. Theneoplastic lesions comprised of adenocarcinoma. A single case of ampullary carcinoma was alsonoted. Percentage of concordance between endoscopic & histologic diagnoses was calculated whereinduodenitis, scalloping, polypoidal & carcinomatous lesions showed 100%, 60.7%, 0% & 100%concordance between the two diagnostic modalities respectively. The conclusion of the study wasthat endoscopic examination alone might miss out in diagnosing majority of the lesions. So, histologicalexamination in adjunct with endoscopy should be considered as much more valuable diagnostic toolrather than endoscopy alone.
