Background. A study was designed to see the role of fine needle aspiration cytology (FNAC) in palpable breast lumps. Materials and Methods. Four hundred and twenty five (425) patients came to the Department of Pathology King Edward Medical University, Lahore in four years for FNAC of their palpable breast masses from June 2006 to June 2010. FNAC diagnosis was compared with histological diagnosis to see the accuracy of fine needle aspiration cytology for neoplastic lesions. Results. There were 271/425 benign, 120/425 malignant, and 32/425 suspicious smears. Inadequate samples were repeated twice or thrice, and the degree of success was improved with consecutive repeating approaches. The frequency of inadequacy declined from 86 to 18, and 2 for first, second and third attempts, respectively. The number of repeats increased the diagnostic accuracy of aspirates which is statistically significant (P = .000). Invasive ductal carcinoma was the most commonly reported lesion with maximum incidence in the 4th, 5th, and 6th decades followed by invasive lobular carcinoma and other malignant lesions. The sensitivity, specificity, accuracy, negative predictive value, and the positive predictive value of FNAC was 98%, 100%, 98%, 100%, and 97%, respectively. Conclusion. FNAC serves as a rapid, economical, and reliable tool for the diagnosis of palpable breast lesions because the cytopathological examination of these lesions before operation or treatment serves as an important diagnostic modality.

The aim of this study was to see the usefulness of fine needle aspiration by “theBethesdasystem for reporting Thyroid Cytopathology” (TBS- RTC) for non palpable thyroid nodules through ultrasound-guidance for the evaluation and treatment planning of nonpalpable thyroid lesions. This study was conducted on 200 patients with non palpable thyroid nodules which are very low lying or felt on swallowing; in Department of Pathology and Radiology since January 2011 to June 2012. The patients were scanned and USG- FNAC was performed and reporting was done by “TBSRTC”. Of the 200 specimens 17 samples were nondiagnostic or unsatisfactory (Class I), 145 samples were benign (Class II), 20 samples were showing Atypical of Undetermined Significance (AUS) or Follicular Lesion of Undetermined Significance (FLUS); (Class III), 6 were showing follicular neoplasm or suspicious for a follicular neoplasm (Class IV), 7 samples were suspicious for malignancy (Class V) and 5 samples were positive for malignancy (Class VI). On comparison of ultrasound guided FNAC with histopathology the sensitivity for correct diagnosis was 93%, specificity was 86%, positive predictive value was 37%, negative predictive value was 99% and accuracy was 86%. USG-FNAC is a useful modality for the evaluation and treatment planning of nonpalpable thyroid lesions smaller than5 mmin the maximum diameter. TBSRTC is the best method of reporting but class III and IV are the main pitfall of this system for reporting Thyroid Cytopathology and show high sensitivity, specificity and accuracy.

Objective: To find out the frequency of benign and malignant skin adnexal neoplasms. Study design: Descriptive study. Materials and methods: It is a descriptive study in which we studied all cases of skin adnexal tumors that are registered in Mayo hospital over the period of six months. Tumors were evaluated according to the type and site , age and gender of the patient. The tumors are classified by WHO classification. Data collected was analyzed using SPSS Version 21 for statistical analysis. Results:  45 skin adnexal tumors were studied in which, 40 (88.9%) were benign and 5 (11.1%) were malignant. Conclusion: Skin adnexal tumors are comparatively uncommon lesions. Benign neoplasms are more frequent than malignant.

The purpose of this study is to find empirical evidence on whether work from home or residential emissions reduces office emissions. Based on existing research the study supports that there are short-term effects on office emissions, i.e., carbon emissions do not outshine the long-term effects. The shift from offices to working from home due to COVID-19 regulations meant more people operating from home as maintaining their position in the market was crucial. The potential research area is to understand how this would affect energy usage and carbon emissions. This study has used a before and after mixed approach to collect data from 301 working-from-home employees and 348 top managers who are responsible for monitoring the employees in a work from home setting. Convenience sampling helped collect responses in a timely manner as offices were not allowing visitors and collecting data in person was difficult, so online surveys were conducted. Work from home reduced usage of office equipment, transportation, pollution, etc. The air quality improved considerably but our findings show that the low emissions were only short-lived. This was not a long-term scenario as organizations kept practicing their operations even at home and the emissions stayed in the environment. Future suggestions and implications are also provided. The results give new insights to researchers in the field of sustainability and the environment.

Background: Thyroid gland is notorious for carrying commonest endocrine pathologies and also for commonest endocrine malignancy. It is the 5th most common cancer in human beings. This makes to carry out current study to get insight of frequency of thyroid lesions at tertiary care level. Methods: This was a descriptive cross-sectional study. The study was done at the Department of Pathology, King Edward Medical University Lahore with the collaboration of four surgical units of Mayo Hospital Lahore from 2010 to 2019. Total 1601 cases were included. Information about age, sex and diagnosis was entered in the pre designed proforma. SPSS version 22 was used for data analysis. Descriptive analysis was done and the results were presented as frequencies, percentages and ratios. The results were then studied against local and international data. Results: This study revealed non neoplastic and neoplastic lesions as 1323 (82.63%) and 278 (17.37%) respectively. Bulk of the lesions 61.6% were between the age bracket of 20-39 years. Mean±SD for age was 34.22±11.42 years. Female to male ratio(F:M) was in favour of females as 9.81:1. Among the non neoplastic lesions, MNG 1151(87%) was a dominant lesion followed by TH 82(6%). LT 29(2.19%) and HT 26(1.96%) were other important lesions. F:M ratio was 10.80:1. Neoplastic lesions were divided into benign 178(64%) and malignant tumors 100(36%). FA was the leading benign neoplasm 164(59%). Rest of the benign tumors shared a minor fraction except HCA 12(4.31%). Among the malignant category, Papillary carcinoma 69(24.82%) dominated over MC 12(4.31%). FC 7(2.51%) and AC 6(2.15%) were other significant findings. F:M ratio in malignancy was 3.16:1 which was significantly lower than 13.83:1 in benign tumors. Conclusion: MNG is the dominant lesion among the non neoplastic lesions while in the neoplastic category FA was leading as benign neoplasm. Papillary carcinoma turned out to be the commonest malignant tumor. Major share of all the lesions were seen between 20-39 years.
