Background: Cervical cancer is a leading cause of mortality and morbidity among women worldwide and most common gynaecological cancer in developing countries. Papanicolaou smear is a simple and cost effective screening test for cervical cancer. The aim of this study is to evaluate and interpret the cervical pap smear cytology in a tertiary hospital. The interpretation and reporting of the pap smear is based on 2001 Bethesda system. Materials and methods:This is a prospective study conducted in a tertiary hospital, Nepal Medical College over a period of two and a half years (January 2013 to June 2015). All cervical pap smears received in the department of Pathology in the study period were included.Results: A total of 4160 cervical pap smears were reported in the study period. Majority of the cases were Negative for Intraepithelial lesion or malignancy (87.9%). Bacterial vaginosis, atrophy and reactive cellular changes associated with inflammation were seen in 5.3%, 2.4% and 1.5% cases respectively. Epithelial cell abnormalities (0.5%) include Atypical squamous cells of undetermined significance, Low grade squamous intraepithelial lesion and High grade intraepithelial lesion. 88% of Low grade squamous intraepithelial lesion was seen in reproductive age group (20-45 years). Conclusion:Cervical cancer is the most common gynaecological cancer in the developing countries. Pap smear is the simple and cost effective screening tool to detect pre invasive cervical epithelial lesions.

Background: Fine needle aspiration cytology is a minimally invasive technique used in the initial diagnosis of different types of lesions located in head and neck region commonly originating from cervical lymph node, thyroid gland, salivary glands and soft tissues. The objective of this study was to evaluate the diagnostic accuracy, sensitivity and speci city of FNAC in various head and neck lesions in correlation with their histopathological examination. Materials and methods: A hospital based prospective study was conducted among 209 patients with palpable head and neck region swellings in the Department of Pathology, Bhaktapur Cancer Hospital and the Department of Pathology, Nepal Medical College from August 2014 to July 2015. FNAC were done from palpable masses of head and neck regions. Data entry and analysis were done using SPSS 17. Result: There were 209 FNAC cases enrolled, out of which lymph node lesions (n=128) were the most common lesions followed by thyroid (n=40), other soft tissues (n=27) and salivary gland (n=14). Reactive lymph nodes, colloid goiter, epidermoid cyst and sialadenosis were the predominant diagnosis of lymph nodes, thyroid gland, soft tissues and salivary gland respectively. Highest accuracy, sensitivity and speci city were observed in thyroid gland, salivary gland and soft tissues. However, four false negative results for malignancy were reported in lymph node lesions. Conclusion: Head and neck region swellings are the commonly encountered conditions. FNAC being highly accurate, sensitive and speci c makes it useful and reliable procedure for screening and diagnosis of palpable masses in head and neck region.

Abnormal uterine bleeding (AUB) is defined as any change in the frequency of menstruation, duration of flow or amount of loss. Menstrual disturbances and different endometrial pattern may accompany and precede thyroid dysfunction. The objective of the study was to correlate thyroid profile with endometrial biopsy in cases of AUB. This study was conducted on 74 patients who presented with AUB, had undergone TFT and endometrial biopsy/hysterectomy. Among 74 patients, thyroid disorders were identified in 26 patients. Maximum number of patients with AUB belonged to the category of hypothyroidism (27%) and 8.1% of cases had hyperthyroidism. In the present study 29 (39.1%) had proliferative endometrium, followed by secretory pattern in 21 (28.4%) patients. Hormone induced changes was seen in 3 (4.1%) patients. Disordered proliferative endometrium and endometrial hyperplasia was observed in 6 patients (8.1%) each. Malignant lesion was not common and it comprised of only 1.4% cases. AUB is frequently seen in patients with thyroid dysfunction. Thyroid function test is a cost effective, easily available test and can detect a possibly curable cause of AUB and avoid unnecessary intervention like hormonal treatment and hysterectomy. AUB due to endometrial cause is an age related pathology. Histopathological examination of endometrial biopsy is a major diagnostic tool in evaluation of AUB. It helps the physician to plan therapy for successful management of AUB.

Background: In the laboratory, errors can occur at any stage of sample processing; pre-analytical, analytical, and post-analytical. Since the pre-analytical phase is the most common source of laboratory errors, the goal of this study is to identify the types and frequency of pre-analytical errors in the hematology laboratory.Materials and Methods: This is a cross-sectional descriptive study done at Nepal Medical College Teaching hospital for a duration of nine months (January 2020 to September 2020). All blood samples received at the hematology laboratory were included whereas biochemistry and special tests blood samples were excluded. Samples were checked for misidentification (incorrectly labeled vials/vials without labels/incorrectly filled forms), incorrect samples (wrong choice of vials), clotted samples, inadequate samples, diluted samples, hemolyzed samples. The errors that occurred in these samples (both inpatient and outpatient) were noted down and measures were taken accordingly before analyzing the sample.Results: The total number of samples received was 15,337. Pre-analytical errors were seen in 857 samples (5.5%). Inadequate samples (25%) were the most common error followed by incorrect samples (20%), hemolyzed samples (20%), misidentification (14%), clotted samples (12%), and diluted samples (9%). Complete blood count test was most affected. Samples from the inpatient department were most affected.Conclusions: The preanalytical error rate in the hematology unit was 5.5% with an inadequate sample being the commonest error. Most of the errors were seen in the test requested for a complete blood count. Samples from the inpatient department showed the most errors.

Background: Pleural effusion is a common medical condition with many possible underlying etiologies. However, Tuberculosis is the most common cause of pleural effusion especially in countries like Nepal. Pleural fluid lymphocytosis is seen in tuberculosis, malignancy and few auto-immune diseases. Adenosine Deaminase activity (ADA) level in tubercular pleural effusion is markedly increased compared to non-tubercular effusions. ADA estimation being a simple colorimetric method is suitable for the rapid diagnosis of tubercular effusion. This study aims to correlate the diagnostic efficacy of ADA with the value of differential count (lymphocytosis) in establishing different etiology of pleural effusion. Materials and Methods:This is a cross sectional study of 50 cases with pleural effusion carried out in the department of Pathology, Green city hospital for the duration of Twenty one month's dating from October 2014 to July 2016 AD.Results: Of all, tubercular pleural effusion accounted for 26%. ADA level was raised (≥40U/L) in 92% of Tubercular pleural effusion. The sensitivity and specificity of ADA alone to diagnose tubercular pleural effusion was 92% each and when lymphocytosis alone was considered sensitivity was 85% with specificity of 32% whereas the combined effect of both ADA with lymphocytosis was 100% (sensitivity) and 87% (specificity), 83% (positive predictive value) and 100% (negative predictive value) respectively with statistically significant p value (<0.05). Conclusion:We can conclude that the combination of pleural fluid differential count (lymphocytosis >50%) and ADA level >40U/L provides with much more positive result than each component alone in differentiating tubercular effusion from other etiologies.
