Modern Plastic Surgery 2023年第4期13卷 106-117页

作者： Medhat Emil Habib Omar Alameri anoud alqaydi Dalal Al Mansoori Aysha Al Naqbi Shamsa Alameri Dalia Medhat Habib Department of Plastic and Reconstructive Surgery Zayed Military Hospital Abu Dhabi UAE

Aim: Excessive increase of weight followed by massive weight loss distorts the shape of the umbilicus as part of the affected skin of the abdomen. There is usually discrepancy between the elongated umbilicus at the time the patient was gaining excessive weight and the thinned abdominal wall after the massive weight loss. This study discusses a procedure that aims at restoring the shape of the umbilicus to its original shape as much as possible. Patients and Methods: In 4 years retrospective study from the 1st of March 2016 till the end of February 2020, the files of the patients who underwent abdominoplasty after massive weight loss with umbilicoplasty performed, as part of the procedure, were reviewed. In these patients the caudal part of the umbilicus at 6 o’clock site was excised in an oblique direction with slanting cut going to both 3 and 9 o’clock directions to shorten the elongated umbilicus keeping the cephalic part at 12 o’clock intact. This residual elongated cephalic part was utilized to make the shape of the hood of the umbilicus. A bolster suture was used at 12 o’clock to add a small depression above the hood. This technique gave the umbilicus the vertical “T” triangular shape with hooding. A questionnaire to assess patients’ satisfaction regarding the shape, depth, location, size, scarring and overall result of the umbilicoplasty procedure was conducted. The questionnaire used a five-point Likert-type scale as follows: 1 (poor), 2 (fair), 3 (good), 4 (very good), and 5 (excellent). Results were collected and evaluated. Results: 197 patients underwent full abdominoplasty surgery during this 4 years study. Those who underwent umbilicoplasty during the abdominoplasty procedure were 34 patients. The results of the questionnaire could be obtained from 23 patients of them. Each patient gave a number from 1 - 5 for each aspect of the questionnaire of the umbilicus shape, depth, location, size, scarring and overall result. This resulted in total number of poin

作者： Mohammad Binhammad Shaikha alqaydi Azzam Othman Laila Hatim Abuljadayel Department of Computer Science British University Dubai Dubai The United Arab Emirates Department of Cybersecurity Dar Al Hekma University Jeddah Saudi Arabia

This article signals the use of Artificial Intelligence (AI) in information security where its merits, downsides as well as unanticipated negative outcomes are noted. It considers AI based models that can strengthen or undermine infrastructural functions and organize the networks. In addition, the essay delves into AI’s role in Cyber security software development and the need for AI-resilient strategies that could anticipate and thwart AI-created vulnerabilities. The document also touched on the socioeconomic ramifications of the emergence of AI in Cyber security as well. Looking into AI and security literature, the report outlines benefits including made threat detection precision, extended security ops efficiency, and preventive security tasks. At the same time, it emphasizes the positive side of AI, but it also shows potential limitations such as data bias, lack of interpretability, ethical concerns, and security flaws. The work similarly focuses on the characterized of misuse and sophisticated cyberattacks. The research suggests ways to diminish AI-generating maleficence which comprise ethical AI development, robust safety measures and constant audits and updates. With regard to the AI application in Cyber security, there are both pros and cons in terms of socio-economic issues, for example, job displacement, economic growth and the change in the required workforce skills.

Modern Plastic Surgery 2020年第3期10卷 75-81页

作者： Medhat Emil Anood alqaydi Dalal AlMansoori Dalia Medhat Habib Marwa Alawadhi Abrar Alteneiji Omar Alameri Department of Plastic and Reconstructive Surgery Zayed Military Hospital Abu Dhabi United Arab of Emirates

We report a case of blast injury to the left hand which resulted in fractures of the fingers with exposure of bones and joints of the phalanges. We used three reverse adipofascial cross finger flaps raised at the same time from 2 fingers to reconstruct adjacent fingers of the patient. The patient recovered well postoperatively and had good range of movement of the fingers. This avoided the complications of the use of regional or distal flaps. To our knowledge, this is the first case reported in which three reverse adipofascial cross fingers flaps are raised at the same time, two of them from an injured finger, to cover three raw areas on two fingers of a patient.

Aim: The aim of this study is to analyze the outcome of cases who underwent abdominoplasty surgery in our facility for the last five years. Patients and Methods: This is a retrospective study analyzing the outcome of patients who underwent abdominoplasty from the beginning of January 2015 till the end of December 2019 in Zayed Military Hospital, Abu Dhabi, United Arab of Emirates. Postoperative complications were recorded. The effects of risk factors including age, sex, smoking, body mass index, associated comorbidity, previous bariatric surgery and combined procedures were evaluated. Results: 213 patients were included in this five-year study. Majority of the patients were females 161 cases (75.6%) while males presented 52 cases (24.4%). The mean age was 38.3 years. The mean BMI was 27 Kg/m2. 127 patients had previous bariatric surgery (59.6%) while 86 patients had not (40.4%). There were no major systemic complications in the cases as deep venous thrombosis, pulmonary embolism or paralytic ileus. There was no mortality in the study cases. Out of the 213 cases included in the study, 23 patients developed haematoma (10.8%), 8 patients developed seroma formation (3.8%), 3 patients had wound infection (1.4%) and one patient had tissue necrosis (0.5%). The complication rate was higher in males 36.4% compared to females 9.9% (p 2 or less had less complications 14.3% compared to those above that level 21.2% although it was not a significant difference (p = 0.231). 55.7% of the smokers had complications while the incidence among non smokers was 8.5% (p < 0.005).

Objective: This study aims at assessing the relation between smoking and the incidence of haematoma formation in abdominoplasty surgery cases. Patients and Methods: This is a 4 years retrospective study involving the patients who underwent abdominoplasty surgery between the period of May 2015 and April 2019 in Zayed Military Hospital, Abu Dhabi, United Arab of Emirates. The incidence of haematoma formation was assessed in relation to tobacco use in these patients. Results: 164 patients met the inclusion criteria of the study. 35 patients were smokers (21.3%) and 129 patients were non-smokers (78.7%). The mean age was 38.4 (21 - 59 years). The mean BMI was 27 kg/m2 (21.4 - 34.7 kg/m2) and the mean hospital stay was 6.5 days (4 - 19). 23 patients in the study developed haematoma (14%). 11 of them had surgical evacuation of the haematoma (6.7%) while the rest were aspirated in the out-patient clinic. Out of the 23 patients who developed haematoma, 17 patients were smokers and 6 were non-smokers. The incidence of haematoma among smokers was 48.6% (17 out of 35 cases) while its incidence among nonsmokers was 4.7% (6 out of 129 cases) showing a clear relationship between smoking and hematoma formation (p Conclusion: Our study shows a direct relationship between smoking and haematoma formation in abdominoplasty cases. Cessation of smoking during the perioperative period is required before embarking on such a procedure.

Objective: This study aims at assessing the incidence of haematoma formation in abdominoplasty cases who had previous bariatric surgery and in those who did not have bariatric surgery before. Patients and Methods: This is a 4 years retrospective study involving patients who underwent abdominoplasty surgery between the period of July 2015 and June 2019. The incidence of haematoma formation was assessed in relation to history of previous bariatric surgery in these patients. Results: 164 patients met the inclusion criteria of the study;46 of them were males and 118 were females. The mean age of the patients included in the study was 38.6 (21 - 60 years). The mean BMI was 27 kg/m2 (21.4 - 34.7 Kg/m2). The mean hospital stay was 6.6 days (4 - 19 days). 107 patients had history of previous bariatric surgery performed and 57 had not. 21 patients developed haematoma (12.8%). 16 of the patients who had haematoma had previous bariatric surgery done (15% of post bariatric surgery cases) while 5 patients developed haematoma with no history of previous bariatric surgery (8.8%). Sixteen male patients out of the 46 male patients in the study developed postoperative haematoma (34.8% of the male patients) while only 5 of the 118 female patients developed postoperative haematoma (4.2% of the female patients) which shows a significant difference in haematoma formation when comparing males to females in general (p Conclusion: Our study shows that the incidence of post abdominoplasty haematoma formation is significantly higher in male patients who had bariatric surgery before when compared to those who had not (p < 0.05). The incidence was higher in males when compared to females (p < 0.001) indicating that males with previous history of bariatric surgery have the highest chance of developing haematoma formation.
