ABSTRACT
Aim: This study was aimed to assess the knowledge, attitude and practices regarding refractive error correction surgeries among undergraduate medical students.Study Design: In this study cross-sectional study design was used.Duration and Place of Study: The study was conducted amongst the undergraduate MBBS students studying at Dow Medical College, Karachi. The duration of study was seven months (August, 2019 till February, 2020).Methods: A sample size of 189 was calculated for the study with confidence level 95% and confidence limit 5%. Data was collected through a validated self-administered questionnaire which was divided in five subsections used to gain information regarding participant抯 demographics, knowledge, attitude and practices regarding refractive error surgeries. Data was analyzed using IBM SPSS V.22.Results: In our study 189 students with a mean age of 21�8 years were included. Among the participants 112 (59.3%) had refractive errors. Glasses were used by majority 76 (67.9%) of participants for visual correction. Use of refractive error correction methods at all times was reported by 72 (66.7%) participants. Majority of respondents 142 (75.5%) had heard about surgery being used for correction of refractive errors. A large number of students 117 (66%) refused for surgery and fear of the outcomes was one of the reason for this refusal.Conclusion: We found that majority of the participants were aware about refractive error correction surgeries yet most of them showed unwillingness for these procedures. This negative attitude must be changed to positive in order to enhance the practice for these procedures.
ABSTRACT
Breast cancer is known from ancient time,and the treatment strategy evolved as our understanding of the disease changed with time. In 460 BC Hippocrates described breast cancer as a humoral disease and presently after a lot of studies breast cancer is considered as a local disease with systemic roots. For most of the twentieth century Halsted radical mastectomy was the "established and standardized operation for cancer of the breast in all stages, early or late". New information about tumor biology and its behavior suggested that less radical surgery might be just as effective as the more extensive one. Eventually, with the use of adjuvant therapy likeradiation and systemic therapy, the extent of surgical resection in the breast and axilla got reduced further and led to an era of breast conservation. The radiation treatment of breast cancer has evolved from 2D to 3D Conformal and to accelarated partial breast irradiation, aiming to reduce normal tissue toxicity and overall treatment time. Systemic therapy in the form of hormone therapy, chemotherapy and biological agents is now a well-established modality in treatment of breast cancer. The current perspective of breast cancer management is based on the rapidly evolving and increasingly integrated study on the genetic, molecular , biochemical and cellular basis of disease. The challenge for the future is to take advantage of this knowledge for the prediction of therapeutic outcome and develop therapies and rapidly apply more novel biologic therapeutics.

Multiple myeloma was diagnosed in 84 residents of Jammu & Kashmir between 1984-1988. The data were analyzed for variations of demographic factors, ethnicity and location of residence (urban/rural). The average annual incidence per 100,000 residents was 1.28. The rates for males and females were 2.02 and 0.71 per 10(5) persons/year respectively. The average incidence rate for Muslims was significantly higher than that for Hindus. Urban residents had significantly higher rates than rural population. Highest incidence rate (14.39) was in the age group of 65 yr and above.
