Advances in Breast Cancer Research 2017年第4期6卷 107-116页

作者： Ahmed Mohamed Farahat Amr Abdel Meguid Attia Mohamed Aly M. El Shafei El Zawahry Mohamed H. Zedan hussein osama soliman National Cancer Institute Cairo University Giza Egypt

Background: The introduction of oncoplasticbreast surgery, with a concomitant contralateral symmetrization procedure, allows the surgical oncologist the freedom to perform wider excisions, with more favorable cosmetic outcomes. Objective: To assess the feasibility of bilateral breast reduction for the management of breast cancer, and to determine the most suitable surgical technique of therapeutic mammoplasty for each patient. And to evaluate the cosmetic outcome during the postoperative period. Methods: This study was from June 2014 until June 2016, and included 86 female patients with breast cancer;divided in 3 groups;group A;had bilateral superior pedicle reduction mammoplasty, group B;had bilateral inferior pedicle reduction mammoplasty, group C;had bilateral batwing mastopexy. 1 month postoperative, patients were asked to answer a 5-scale questionnaire evaluating their own cosmetic outcome. Criteria they were asked to evaluate were: symmetry, shape and volume, projection, correction of ptosis, visibility of the scars and overall satisfaction. A similar questionnaire was answered by a panel made up of a surgeon and breast-care nurse after seeing the pre- and post-operative photos of the patients in question. Results: Group A had a mean tumor size of 2.7 ± 0.69 cm, least resected margins 1.2 - 4.3 cm, Group B had a mean tumor size of 3.2 ± 1.19 cm, least resected margins 0.7 - 3.8 cm, Group C had a mean tumor size of 3.4 ± 1.12 cm, least resected margins 1.7 - 5.2 cm. Cosmetic results fared high above average. Group C fared better in overall satisfaction but Group B fared better in ptosis correction, projection and symmetry. The panel answers showed difference regarding shape and volume;the only two criteria to be almost of the same result among the three groups. Conclusion: Bilateral TM has some advantages when compared to standard conventional BCS techniques without having any unfavorable effects on surgical margin confidence, local recurrence, and survival rat

Background: The need to establish a strong culture around radiation safety is derived from the assertion that medical practitioners, patients, and third parties should not be exposed to unnecessary radiation. Authorities have endeavored to enact policies to protect all employers and patients in radiology departments. Objectives: To assess the impact of radiation safety practices and regulations on the ongoing improvements in radiation safety culture and practices in radiology departments. This will be achieved through a subjective assessment of national and international rules and regulations by healthcare professionals. Materials and Methods: We conducted a questionnaire survey in the radiology departments of three JCI-accredited hospitals in the Riyadh region to identify and assess the impact of national radiation regulations and the accompanying processes on the improvement of radiation safety culture and practices in radiology departments. Results: There were statistically significant differences in the grading system results among various groups of respondents, based on their educational level. Also, there are statistically significant differences between the assessments of safety level results in the answers provided by various groups of respondents according to education level in favor of the master’s degree. Conclusion: The study concludes that technicians with a diploma degree require stricter regulation. Furthermore, the results of this study suggest that an exposure tracking system and a regulatory action supporting it may be useful in the ongoing task of improving patients’ radiation safety.

Comparative Study between Lidocaine 2% and Dexamethasone Local Wound Infiltration Effect on Postoperative Pain Post Mastectomy: A Randomized Controlled Study

引用

Advances in Breast Cancer Research 2018年第4期7卷 243-249页

作者： hussein O. soliman National Cancer Institute Cairo Egypt

Objective: To compare the efficacy and safety of Lidocaine 2% versus Dexamethasone injected locally in mastectomy wound as pain relieving agents. Materials & Methods: A randomized single-blinded study in which 50 patients candidate for Mastectomy were included. Participants were equally randomized into two groups;Group A, in which patients received 10 ml Lidocaine 2% and Group B, in which patients received 16 mL Dexamethasone. In both groups, the drugs were given via local infiltration in the subcutaneous layer of the Mastectomy wound immediately after skin closure. Pain control was assessed post-operatively in the first 24 hours using the visual analogue scale (VAS) in addition the need for additional analgesia was recorded. Results: There was a statistically significant lower VAS score in group A (Lidocaine group) when compared to those in group B (Dexamethasone group) 1 h, 6 h, 12 h postoperatively with no significance 24 h postoperatively (36% vs 64% 1 h, 28% vs 64% 6 h, 30% vs 72% 12 h and, 80% vs 60% 24 h). This statistical significance was evident throughout the post-operative hours (1 h, 6 h, 12 h). Though local Lidocaine caused marked improvement of pain in bigger number of patients in group A than group B, yet it showed no statistical significance 24 h post-mastectomy. Furthermore, the number of participants that needed additional doses of analgesia lower in group A (48% vs 56%) in comparison to group B, but still showed no statistical significance. Conclusion: Local injection of Lidocaine 2% in Mastectomy wounds, has an upper hand in reducing the post-operative pain and showed a lesser need for post-operative analgesia when compared to local Dexamethasone injection.

Evaluation of an interferometric distance meter

引用

Journal of Measurement Science and Instrumentation 2014年第3期5卷 73-78页

作者： osama Terra Hatem hussein Mohamed Amer Primary Length Standard and Laser Technology Laboratory National Institute for Standard (NIS) Engineering and Surface Metrology Laboratory National Institute for Standard (NIS)

This paper discussed the main parameters contributing to the measurement uncertainty of interferometric distance meter （IDM）. A simple and robust set-up is used to measure distance of about 12 cm with an expanded uncertainty （ k = 2） of ±16.4 μm. The measurement uncertainty is found to be limited by the wavelength measurement accuracy. This set-up can be used to measure distances up to 56 m. It also enables easy determination of the point of equal path difference between the measuring and the reference arms. LabVIEW program is used for counting of the fringes and applying fast Fourier transfor- mation （FFT） to perform frequency selective filtration to the noise. Although the reported uncertainty does not represent the state-of-art uncertainty reached for similar distance, the measurement provides traceable measurement to the unit of length, the meter.

引用

Journal of Cancer Therapy 2018年第7期9卷 559-567页

作者： hussein O. soliman Yossra Lashin Department of Surgical Oncology National Cancer Institute Cairo University Giza Egypt Department of Gynecology and Obstetrics Faculty of Medicine Cairo University Giza Egypt

Context: Condyloma acuminatum is a common morbidity caused by human papillomavirus infection. Objective: To compare the recurrence rate after surgical excision with or without podophyllin cautery. Design, Setting, Participants: Sixty women were enrolled in a study that was conducted in Cairo from Jan-2017 to Mar-2018. Interventions: All women received the same preparations. After randomization;in the study group (N = 30), podophyllin cautery was added to surgical removal in the follow-up period. In the control group (N = 30), only surgical removal was used. Main Outcome Measure: The main outcome measure was the estimation of the recurrence of the lesion during the follow-up period. The secondary outcome measures were the incidence of adverse events. Results: Both groups were comparable (p-value > 0.05) with regard to the age and BMI. Recurrence was significantly lower (P = 0.001) in the study group than the control group. In the study group, five cases (17.2%) have recurrence whereas, in the control group, 18 (60.0%) had suffered recurrence. The ARR was 42.8% (CI 95%: 18% - 60.9%) with RR of 0.29 (CI 95%: 0.12% - 0.67%) and NNT2 (CI 95%: 6% - 2%). During the follow-up period, 19 cases (65.5%) of the study group experienced pain versus only eight cases (26.7%) in the control group (p = 0.003). However, the development of scars was less in the study group 7 (24.1%) than in the control group 19 (63.3%), (p = 0.002). Conclusion: Podophyllin cautery, when added to surgical removal, is effective in decreasing the incidence recurrence in cases with condylomata acuminata.
