Background: Thalassemia is a type of congenital anemia, where there is deficient synthesis of one or more type of globin subunits of normal hemoglobin. This study was undertaken with aims & objective to study the prevalence of thalassemia by comparing Red Blood Cell indices, Peripheral Blood Smear and Electrophoresis in adult volunteers. Material and Methods: The study comprised of 518 cases attending hematological department, who were enrolled in our study after proper informed consent, of which 462 cases were further studied. All cases were subjected to blood sampling for estimation of Hemoglobin, red cell indices and peripheral blood smear. Those samples where peripheral blood smear and Red cell indices were suggestive of thalassemia were subjected to Bio-Rad High Performance Liquid Chromatography based electrophoresis to observe the presence of any abnormal hemoglobin. Results: The mean age of screening sample was 42.91 ± 16.85 years with minimum age of 18 years and maximum age of 85 years. The highest number of cases was in between 21-30 years age groups (19.5%) followed by 41-50 years (17.7%). In the study group, 299 (64.7%) cases were male and 163 (35.3%) cases were female. The prevalence of anemia was found to be 48.16% in males and 68.71% in females with overall prevalence of 55.41%. On electrophoresis reports, 19 cases were diagnosed with thalassemia. The only thalassemia observed was thalassemia minor. The prevalence of thalassemia was found to be 4.11%. Conclusion: Significantly high prevalence of thalassemia minor is found in healthy population.
Background : Breast cancer is one of the commonest cancers in female. FNAC is safe and cost affective screening test for breast lump having both high sensitivity and specificity. Our aim is evaluation of diagnostic accuracy of fine needle aspiration cytology [FNAC] in diagnosis of breast lesions.Material and Methods: All male and female patients with breast lesion were subjected to cytological evaluation of which many were followed up with histopathological evaluation to assess the diagnostic accuracy of FNAC.Results : Out of 1088 cases diagnosed on FNAC, 703 cases (64.61%) were benign and 232 cases (21.3%) were found to be malignant. In our study the most common benign lesion was fibroadenoma and commonest malignant lesion was Duct carcinoma. Maximum cases of breast lesions in females were in the age group of 21- 30 years followed by age group of 31- 40 years. While maximum cases in males were in the age group of 31-40 years & 61-70 years. The sensitivity and specificity of FNAC for cyto-histo correlation were found to be 97.16% and 92.83% respectively.Conclusion : FNAC is a highly sensitive and specific test for diagnosis and categorization of breast lesions into different categories of neoplastic and non-neoplastic breast lesions.Journal of Nobel Medical College Volume 6, Number 2, Issue 11, July-December 2017, 66-71
Background: A thyroid swelling is an enlargement of thyroid glands causes by iodine deficiency, ageing, autoimmune disease and benign or malignant tumors. Autoimmune thyroiditis is the second most common thyroid lesion diagnosed after goiter. Materials and Methods: To find out the distribution of thyroid gland swelling in patients visiting otorhinolaryngology department of Nobel medical college and correlate serum thyroid function test and anti-thyroid peroxidase level with fine needle aspiration cytology reports. Results: The mean age of patient with thyroid gland lesions was 40.47 ± 13.05 years. Out of 87 patients studied, the highest number of patients (37, 42.5%) was diagnosed with colloid goiter followed by autoimmune thyroiditis (29, 33.3%). The mean age of patients with autoimmune thyroiditis was found to be 38.66 ± 12.31 years. The sensitivity and specificity of anti-thyroid peroxidase antibodies for diagnosing autoimmune thyroiditis was 89.7% and 94.8% respectively. Conclusion: Autoimmune thyroiditis has statistical correlation with serum anti-thyroid peroxidase antibodies and it can be effectively used as an alternative tool in diagnosing autoimmune thyroiditis with acceptable diagnostic accuracy.
Background: Cervical cancer is a leading health problem among women all over the world with significant mortality and morbidity in developing countries like Nepal. Pap smear is an effective and cost efficient diagnostic technique for cervical lesions. This study aims at histopathological correlation of cervical Pap smears. Materials and Methods: A cross sectional study was conducted from January 2020 to January 2022 in Pathology department of Nobel Medical College Teaching Hospital (NMCTH). 119 cases of cervical Pap smear were reported using the Bethesda system and correlated with histopathological examination findings for various epithelial cell abnormalities. Analysis was done using SPSS software version 20. Results: Out of 5110 smears examined, 119 were positive for epithelial cell abnormalities. Cellular abnormality was commonly seen between 31-60 years of age. Low grade Squamous Intraepithelial Lesion was the commonest lesion found. Pap smear findings had good concordance rates with histopathological findings for individual lesions. The overall sensitivity, specificity, positive predictive value, negative predictive value and diagnostic accuracy of Pap smear were 84%, 23.1%, 89.9%, 15% and 77.3% respectively. Conclusion: Pap smear has a good diagnostic accuracy, sensitivity and positive predictive value in diagnosing cervical lesions in comparison to histopathological examination
Background: Ovarian tumor is the fourth commonest cancer in female in Nepal. About 80% is benign and 20% of these tumors are malignant. Due to its complex nature, vagueness and non-specificity of the symptoms it produces, the ovarian neoplasm can mislead both the doctor and patients. Hence this study was undertaken with aims & objectives to study the morphology of ovarian specimens as well as estimate serum CA125 as screening tool. Material and Methods: A study of over one year comprised of 75 specimens of ovary diagnosed in the Department of Pathology, Nobel medical college and teaching hospital, Biratnagar. After thorough gross examination and preparation of H&E stained slides the lesion of ovary were classified as per WHO classification. Also, preoperative blood samples were obtained from patients for estimation of serum CA125 level. Blood samples was also drawn from 20 healthy females in reproductive age group who acted as controls. Results: Of the 75 cases of ovarian mass, based on histology 75% were benign, and 25% were malignant. Surface epithelial tumors were the commonest (68%) of all ovarian tumor, followed by germ cell tumors (13%), sex cord–stromal tumors (6%). Serous Cystadenoma (29%) was the commonest benign tumor and serous cystadenocarcinoma (9%) commonest malignant neoplasm. CA125 levels was raised in epithelial ovarian cancers. Maximum rise was seen in serous cystadenocarcinoma. Exceptionally a small percentage of epithelial cancer showed normal level (false negative). Also, few benign tumors, non-epithelial tumors and even non-neoplastic lesions showed false positive rise in CA125 (false positive). Conclusion: Accurate histopathological evaluation of ovarian specimen is necessary both in terms of therapeutic intervention as well as prognosis. CA125 is an important screening tool for detection of epithelial ovarian cancers. Journal of Nobel Medical College Volume 7, Number 1, Issue 12, January-June 2018, Page: 30-36
