In this review article, various preferences in breast plastic surgery particularly after breast cancer will be discussed in view of the diverse indications for the different construction procedures. The various conditions that necessitate the need for reconstruction are appraised, the important reconstructive procedures are discussed. The most important indications procedures discussed in this review include;Prophylactic subcutaneous mastectomy, Lumpectomy and Radiation, Modified Mastectomy with Axillary Sampling, Nipple reconstruction, and the contralateral breast. These procedures are discussed in view of plastic surgeon practice and patients acceptability in Saudi Arabia. Data from Saudi Arabia in particular was identified through searches of the EMBASE, and MEDLINE database, using the keywords: Saudi Arabia, breast plastic Surgery, breast reconstruction, autologous breast reconstruction, breast augmentation. Advances in prosthetic technologies and modifications in autologous flap techniques, and the development of novel tissue alternatives have allowed for sustained developments in breast reconstruction results. A variety of attitudes has been accessible for addressing the difficulties that endure after resection of breast cancer in Saudi Arabia. Patients should be educated to accept different process in this context.

Background: Increasing awareness level and health education can reduce the burden of Chronic Kidney Disease (CKD) at community base. Therefore, the aim of the present study was to assess the level of knowledge towards CKD manifestations in Saudi Arabia. Methodology: This is a descriptive prospective study including 900 apparently health Saudi volunteers, their ages ranging from 18 to 65 years old with a mean age of 34 years. A purposeful questionnaire was deliberated and used for obtaining data about the CKD. Results: Out of 900 contributors, 268 (29.8%) were males and 632 (70.2%) were females, giving males:females ratio of 1.00:2.36. About 102/900 (11.3%) of the participants (all of them were females) were found to believe that CKD has no specific symptoms. Conclusion: The awareness towards CKD manifestation is relatively low, which necessitates the important of community based intervention including health educational programs.

Background: The risk of CKD is high in Saudi Arabia due to increasingly growing prevalence of its risk factors, such as diabetes, hypertension and obesity. Therefore, the objective of this study was to assess the level of awareness of Saudi population towards CKD risk factors in order to generate platform for future planning. Methodology: This study included 940 apparently healthy Saudi volunteers, their ages ranging from 17 to 65 years old with a mean age of 35 years. A purposeful questionnaire was designed and used for obtaining data about the CKD risk factors. Results: Out of 940 participants, 293 (31.2%) were males and 647 (68.8%) were females, giving males “females” ratio of 1.00:2.21. About 62.3% of the participants were found to believe that DM is one of the main risk factors for CKD, of whom, 74% were males and 57% were females. Approximately 60% of the participants were found believing that hypertension is one of the main risk factors for CKD, of whom 79.5% were males and 51.6% were females. Conclusion: There is an increasing in the prevalence of CKD risk factors among Saudi population. Although, the levels of awareness toward some CKD risk factors are relatively increasing, but more health education efforts are deemed importance.
