Tracking the epidemiological trends of female breast cancer in Saudi Arabia since 1990 and forecasting future statistics using global burden of disease data, time-series analysis.

BACKGROUND: Female breast cancer stands as the prime type of cancer in the Kingdom of Saudi Arabia (KSA), with a high incidence and mortality rates. This study assessed the burden of female breast cancer in KSA by analyzing and forecasting its incidence, mortality, and disability-adjusted life years (DALYs). METHODS: We retrieved data from the Global Burden of Disease (GBD) about female breast cancer from 1990 to 2021. Time-series analysis used the autoregressive integrated moving average (ARIMA) model to forecast female breast cancer statistics from 2022 to 2026. RESULTS: From 1990 to 2021, KSA reported 77,513 cases of female breast cancer. The age groups with the highest number of cases are 45-49 years, followed by 40-44 years, 50-54 years, and 35-39 years. The analysis also showed fewer cases in the younger age groups, with the lowest number in the less than 20-year-old age group. From 1990 to 2021, KSA reported 19,440 deaths due to breast cancer, increasing from 201 cases in 1990 to 1,190 cases in 2021. The age-standardized incidence rate/100,000 of breast cancer increased from 15.4 (95% confidence interval (CI) 11.2-21.0) in 1990 to 46.0 (95%CI 34.5-61.5) in 2021. The forecasted incidence rate of female breast cancer will be 46.5 (95%CI 45.8-46.5) in 2022 and 49.6 (95%CI 46.8-52.3) in 2026. The age-standardized death rate per 100,000 Saudi women with breast cancer increased from 6.73 (95%CI 6.73-9.03) in 1990 to 9.77 (95%CI 7.63-13.00) in 2021. The forecasted female breast cancer death rate will slightly decrease to 9.67 (95%CI 9.49-9.84) in 2022 and to 9.26 (95%CI 8.37-10.15) in 2026. DALYs increased from 229.2 (95%CI 165.7-313.6) in 1990 to 346.1 (95%CI 253.9-467.2) in 2021. The forecasted DALYs of female breast cancer will slightly decrease to 343.3 (95%CI 337.2-349.5) in 2022 reaching 332.1 (95%CI 301.2-363.1) in 2026. CONCLUSIONS: Female breast cancer is still a significant public health burden that challenges the health system in KSA, current policies and interventions should be fashioned to alleviate the disease morbidity and mortality and mitigate its future burden.

Evaluating Lingual Nerve Repair Outcomes: A Systematic Review.

PURPOSE: The lingual nerve (LN) is susceptible to injury during oral and maxillofacial procedures, leading to neurosensory deficits. Advances in microsurgical techniques necessitate a comprehensive review of overall effectiveness and influencing factors. METHODS: A systematic review was performed via Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines to identify studies. Inclusion criteria were full text availability, studies written in english, and studies published after 2000 reporting LN repair. The primary outcome was sensory improvement defined via functional sensory recovery (FSR) or neurosensory testing (NST). Sex, time from injury to repair, method of repair, and graft length were examined to see if each influenced outcomes. RESULTS: A sample of 786 subjects across 17 studies was examined. Most patients were female (73.3%) and suffered injuries from third molar extractions (72.8%). Of the studies, 10 defined improvement by FSR with a total of 88.8% (500/563) of nerves achieving such. Of those achieving FSR, 91% did so within a year. The remaining 7 studies defined sensory improvement by individually setting various NST thresholds, with the combined improvement rate being 88.6% (203/229). Positive outcomes were achieved with graft lengths up to 70 mm. Results on time to repair were mixed. The methods of repairs were not different based on statistical analysis short of performing an equivalence trial. CONCLUSION: Conclusions made from studies using FSR were similar to studies using NST, meaning the method of measuring outcomes does not seem to be a confounder. FSR is the superior scale due to being objective and standardized. LN repair produced high rates of sensory improvement, which is expected to occur within 1 year postoperative. Sex and graft length did not influence outcomes. More research is needed to determine the effect of time to repair on efficacy. Most methods of repair produced similar outcomes, suggesting multiple valid techniques exist.

Screening, awareness and challenges for colorectal cancer treatment in Saudi Arabia: an update.

Colorectal cancer (CRC) is the second most common cancer in the world. In Saudi Arabia, CRC is the most common cancer in males and the third most common in females, and its incidence rate is rising as the country continues to develop. However, the country does not have a national CRC screening program for CRC. This review aims to review recent studies that have attempted to address and rectify this issue and discern the most notable and prevalent barriers. Despite these efforts, guidelines are still lacking. Two prospective studies have been conducted in recent years, one of which was a national pilot screening program conducted by the Ministry of Health (MOH). While both had a similar number of participants, the colonoscopy rate for patients with a positive fecal immunochemical test (FIT) in the MOH program was only 20% compared to 75.8% in the Al-Kharj program. Awareness of the Saudi population regarding CRC and its screening appears to be insufficient. The most common barriers to patients' willingness to undergo screening were embarrassment, fear, and pain. Barriers to physicians are mostly related to factors outside their hands, such as lack of equipment and time. We conclude that efforts should be made to establish a national screening program and improve awareness of the population and physicians.

Effect of Transplanted Bone Marrow on Spleen of Irradiated Pregnant Rats and Their Fetuses.

<b>Background and Objective:</b> Prenatal ionizing radiation exposure may hinder fetal and embryonic growth depending on the dose and gestational age. The current study's objective was to discover how bone marrow transplants affected the spleens of pregnant rats that had been subjected to γ (Gamma) radiation. <b>Materials and Methods:</b> Sixty rats that were pregnant were separated into five different groups, each with 6 females. The pregnant rats in the second Group were exposed to 2Gy of γ-rays. Group III; pregnant rats subjected to 2Gy of γ-rays, followed by an intraperitoneal injection of newly prepared bone marrow transplantation (BMT). The fifth Group were exposed to 2Gy γ-rays and received 1 dosage of BMT an hour later. Spleen samples from the pregnant rats as well as their fetuses were taken for histological and histochemical analyses. <b>Results:</b> Gamma rays damaged the splenic tissue of women and their fetuses on days 7 or 14 of pregnancy in a variety of histological and histochemical ways, although bone marrow transplantation significantly reduced the damage. Treated mothers with bone marrow post-radiation showed a noticeable recovery in spleen of their fetuses. Improved spleen architecture was accompanied by appearance of normal content of collagen, polysaccharides and total protein in the fetal spleen tissue especially on day 7 of gestation. <b>Conclusion:</b> Bone marrow transplantation can lessen the damage caused by gamma radiation.

Evaluating Stromal Vascular Fraction As a Treatment for Peripheral Nerve Regeneration: A Scoping Review.

PURPOSE: This study aims to investigate the potential of stromal vascular fraction (SVF) for peripheral nerve regeneration. METHODS: A scoping review of Scopus and PubMed databases was conducted. Inclusion criteria were human or animal studies exploring the use of SVF for peripheral nerve regeneration. Studies were categorized by assessed outcomes: pain assessment, neural integrity, muscle recovery, and functional recovery. Level of evidence and study quality were assessed. RESULTS: Nine studies met the inclusion criteria. SVF injection in humans with trigeminal neuropathic pain reduced pain scores from 7.5 ± 1.58 to 4.3 ± 3.28. SVF injection improved sensation in humans with leprosy neuropathy. Repairing transected rat sciatic nerves with SVF-coated nerve autografts improved wet muscle weight ratios (0.65 ± 0.11 vs 0.55 ± 0.06) and sciatic functional index (SFI) scores (-68.2 ± 9.2 vs -72.5 ± 8.9). Repairing transected rat sciatic nerves with SVF-coated conduits increased the ratio of gastrocnemius muscle weights (RGMW) (7-10% improvement), myelinated fibers (1,605 ± 806.2 vs 543.6 ± 478.66), and myelin thickness (5-20% increase). Repairing transected rat facial nerves with SVF-coated conduits improved whisker motion (9.22° ± 0.65° vs 1.90° ± 0.84°) and myelin thickness (0.57 µm ± 0.17 vs 0.45 µm ± 0.14 µm). Repairing transected rat sciatic nerves with SVF-coated nerve allografts improved RGMW (85 vs 50%), SFI scores (-20 to -10 vs -40 to -30), and Basso, Beatie, and Bresnahan locomotor scores (18 vs 15). All metrics mentioned above were statistically significant. The human studies were level 4 evidence due to being case series, while animal studies were the lowest level of evidence. CONCLUSION: Despite initial promising results, the low-level evidence from the included studies warrants further investigation.

Folliculotropic mycosis fungoides associated with follicular mucinosis: A case report and mini review.

Key Clinical Message: F-MF is a rare non-classic variant of MF. In the case of hair loss, this should be a diagnostic consideration. The essence of the diagnosis of F-MF is a careful medical history, physical examination, and a combination of immunohistological and molecular analyses (Cureus. 2022; 14:e21231, Ann Saudi Med. 2012; 32:283, Oman Med J. 2012; 27:134, Int J Dermatol. 2016; 55:1396, Saudi Med J. 2018; 39:994 and Case Rep Oncol. 2018; 11:436). Abstract: Mycosis fungoides (MF) is a primary cutaneous T-cell lymphoma with multiple subtypes. Follicular MF (F-MF) is a non-classic variant of MF. Histological features entail folliculotropism and damage of the epithelium lining of the hair follicles with or without mucin deposition. A 52-year-old male patient complained of recurrent skin lesions on the scalp over 8 months. The lesions appeared suddenly, enlarged over time, and became itchy. A skin punch biopsy was performed. Histological features included mucin deposits in the epithelium of the hair follicles and dense, predominantly perifollicular atypical lymphocytes infiltrating the follicular epithelium. The lymphoid cells were composed of CD3-positive T cells (CD4/CD8-positive T cells) with a shift in favor of the former. The case was diagnosed as F-MF on an immunohistological basis. The diagnosis of F-MF is often difficult for dermatologists and dermatopathologists alike. Not only clinicopathological correlations but also immunohistochemical and molecular analysis are required.

Dermoscopy aids in lesion selection for microbiological and histopathological assessment of mycetoma.

Mycetoma, a chronic granulomatous infection of the skin and the subcutaneous tissue, is characterized by discharge of exudate containing grains. This report illustrates the importance of dermoscopy in selecting lesions for both microbiological and histopathological assessment, which are considered the gold standard of diagnosis in mycetoma.

Encyclopaedic Review of Glipizide Pre-clinical and Clinical Status.

Glipizide is an oral glucose-lowering medication that is beneficial for the treatment of type 2 diabetes. This study compiles exhaustively all accessible information on glipizide, from preclinical to clinical studies. Glipizide may be used in concert with TRAIL to treat cancer cells; in vitro studies have shown that it suppresses angiogenesis and vasculogenesis while shielding cells from glycation-induced damage. Anticonvulsant effects and modifications in the pharmacokinetics of other medications, such as Divalproex Sodium, were seen in glipizide in vivo experiments. Propranolol amplifies glipizide's hypoglycemic effect briefly in normal animals but consistently enhances it in diabetic ones. In the treatment of cancer and neurodegenerative poly(Q) illnesses, glipizide has demonstrated to offer potential therapeutic advantages. It is ineffective in preventing DENA-induced liver cancer and may cause DNA damage over time. The way glipizide interacts with genetic variants may increase the risk of hypoglycemia. Combining Syzygium cumini and ARBE to glipizide may enhance glycemic and lipid control in type 2 diabetes. Individuals with coronary artery disease who take glipizide or glyburide have an increased risk of death. The risk of muscular responses and acute pancreatitis is minimal when glipizide and dulaglutide are combined. In conclusion, glipizide has shown promising therapeutic efficacy across a variety of disorders.

Assessing the Efficacy of Allogeneic Nerve Grafts in Trigeminal Nerve Repair: A Systematic Review.

PURPOSE: Our primary objective was to assess the efficacy of allogeneic nerve grafts in inferior alveolar nerve or lingual nerve repair. We hypothesized that using allogeneic nerve grafts would be effective, as evidenced by achieving high rates of functional sensory recovery (FSR). Additionally, we looked if sex, time from injury to repair, etiology of nerve damage, and graft length affected outcomes. METHODS: A systematic review following Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines was conducted. PubMed and Scopus databases were searched using specific search strategies to generate eligible studies. Inclusion criteria encompassed studies reporting use of allogeneic grafts, assessing FSR using either Medical Research Council Scale or Neurosensory Testing, and published within the past 15 years. RESULTS: Across 10 studies conducted between 2011 and 2023, analysis was performed on 149 patients and 151 reconstructed nerves. Allogeneic nerve grafts showed an average FSR rate of 88.0%. Kaplan-Meier analysis of time to FSR postoperatively revealed that of those achieving FSR, 80% achieved it within 6 months and 98% achieved it by 1 year. The mean graft length was 29.92 mm ± 17.94 mm. The most common etiology for nerve damage was third molar extractions (23.3%). Sex distribution among patients revealed that 85 were female (57.0%) and 64 were male (43.0%). CONCLUSION: Our primary hypothesis was supported as nerve allografts achieved high rates of FSR. FSR was achieved in normative timeframes, which is 6 to 12 months postoperatively. Furthermore, allografts reduced the risk of posttraumatic trigeminal neuropathy. Time from injury to repair, graft length, etiology of nerve damage, and sex did not affect FSR. As the assessed variables in our study did not affect outcomes, there needs to be a more nuanced approach to understanding and addressing various factors influencing sensory recovery.

Graves' disease with only unilateral involvement; a case report.

INTRODUCTION: Graves' disease characteristically presents with a diffuse goiter secondary to the autoantibodies that target the thyrotropin receptors of the thyroid gland. Few cases have been reported of only one of the two lobes being affected. The cause of this phenomenon is still uncertain. Here we report on another case of unilateral Graves' disease. CASE PRESENTATION: A 43-year-old female patient presented with a history of weight loss, palpitations and right sided neck swelling for 4 months. Clinical examination showed an enlarged right thyroid lobe. Laboratory investigations yielded evidence of thyrotoxicosis with suppressed thyroid stimulating hormone. In addition, anti-TSH receptor and anti-thyroperoxidase antibodies were positive. Neck Ultrasound showed an enlarged right thyroid lobe with increased vascularization. The isthmus and left lobe were both normal in size. A Tc99m pertechnetate thyroid scan demonstrated enlargement of the right thyroid lobe with diffuse intense uptake, whereas the left lobe was suppressed. A diagnosis of unilateral Graves' disease was made. The thyrotoxicosis was treated and maintained with methimazole. DISCUSSION: Unilateral Graves' disease is a rare manifestation of Graves' disease, sharing the same autoimmune background and the symptoms of thyrotoxicosis. Enlargement of only one lobe was evident on clinical examination. The distinctive feature was unilateral uptake during thyroid scintigraphy. The exact pathophysiology of this condition has yet to be elucidated. Management options and responses are similar to those of classical Graves' disease. CONCLUSION: Unilateral uptake during thyroid scintigraphy and/or unilateral lobar goiter in the setting of hyperthyroidism can be the presentation of unilateral Graves' disease.

Frequency of Diplopia in Zygomatic Complex Fractures-A Cross-Sectional Descriptive Study.

Background: The zygomatic complex is the second most common fracture of the facial bones after the nasal bone. The prominent convex shape of the zygoma makes it vulnerable to traumatic injury. Diplopia is one of the serious complications of zygomatic complex fracture and is a common subjective complaint. Objective: To determine the frequency of diplopia in zygomatic complex fractures. Methodology. A cross-sectional descriptive study was conducted at the Oral and Maxillofacial Surgery Ward, Civil Hospital, Karachi, Pakistan. The duration of the study was 1 year (March 1, 2021 to February 28, 2022). A total of 126 patients having zygomatic complex fractures were included in this study. After recording the patient's complete history, like demographic details and cause for fracture, diplopia was examined clinically. If, during the examination, the patient complained of double vision, this was labeled as diplopia positive (Yes) and negative (No) if the patient did not have any such complain. Data were statistically analyzed. Results: The mean (±SD) age of patients was 33.42 (±9.27), with 91 (72.2%) male patients and 35 (27.8%) female patients. The frequency of diplopia in zygomatic complex fractures was observed in 52 (41.3%) patients. The rate of diplopia was significantly high in patients aged between 31 and 40 years (P-value=0.0005). Conclusion: The frequency of diplopia among patients having zygomatic complex fractures was high in this study. Thus, forming a strategy to properly diagnose and treat it and to prevent persistent morbidity to improve patient's quality of life is recommended.

The Versatility of the Lateral-based Mammary Flap as an "Auto-implant" for Enhancing Breast Mound for Patients Undergoing Primary Mastopexy.

Background: The demand for augmentation-mastopexy surgery without using implants has significantly increased over the years. Fat transfer offers an alternative method, but some patients do not favor this procedure either. The purpose of this study was to evaluate the versatility of using a lateral-based mammary flap as an "auto-implant" for enhancing the breast mound for patients undergoing primary mastopexy. Method: This retrospective study was performed between February 2016 and April 2019, including 36 female patients (72 breasts). Our technique involves using the inferior breast tissue by elevating the lateral-based dermoglandular flap that was moved cranially with a 90 degree rotation in a conical shape within the created pocket to refill the superior and central mound. Result: The mean nipple projection was 11.2 after 36 months postoperative compared with 5.2 before surgery. The mean ± SD of pre- and postoperative measurements for the lower pole zone were 80.2 ± 10.5 and 50.1 ± 6.4, and those for the upper pole zone were 40.3 ± 9.5 and 63.9 ± 6.5, respectively. The distance of breast mound elevation after the surgical procedure ranged from 5.30 to 9.55 cm, with a mean of 7.90 cm. Conclusions: The lateral-based mammary flap acts like an implant that helps shape and augment the breast, enhances the mammary projection, and restores the breast contour without requiring a synthetic implant or fat grafting. It is a reliable technique with high patient satisfaction but is unsuitable for patients with insufficient breast volume.

Outcomes of Open Rhinoplasty for Unilateral Cleft Patients using Photogrammetric Analysis - An Evaluative Study.

Introduction: Secondary cleft rhinoplasty is a challenge due to the complex anatomy of the nose, with structural deformity and difficulty in surgical management. This study aimed to evaluate the effect of an anatomical-based approach on enhancing tip and alar symmetry in secondary unilateral cleft rhinoplasty using photogrammetric evaluation. Methods: The study was conducted on 57 adult patients seeking rhinoplasty after primary repair of congenital unilateral cleft lip deformity. All patients were operated upon using an external open rhinoplasty approach using an anatomical-based surgical technique. The cases were periodically followed up at three, six, 12 and 18 months for both aesthetic and functional outcomes with photogrammetric analysis of facial profile using the software Mirror Suite programme to compare before and after the surgical procedure. Results: The photogrammetric analysis showed a significant improvement of facial angles (P = 0.05). The nasofrontal angle changed from a median of 146° to 132.5°, nasolabial angle of 73° to 95°, nasofacial angle of 21.5° to 32° and nasomental angle of 105° to 130°. The rotation angle of the nasal tip showed a significant cephalic rotation with a mean increase of the tip elongation of 1.8 cm achieved per lateralised millimetre. Discussion: Secondary rhinoplasty in unilateral cleft deformities needs accurate evaluation of the anatomical and pathological abnormalities. Open approach is preferred with using costal cartilage graft allowing adequate columellar lengthening, maxillary enhancement and alar repositioning which leads to optimise the definition, projection and cephalic rotation with better stabilisation and symmetry of the nasal tip.

The Efficacy of Anterior Capsulotomy and Basal Capsulectomy Adherent to Expanded Scalp Flap During Alopecia Reconstruction in Pediatric Burned Patients.

BACKGROUND: Scalp expansion is an optimal treatment for alopecia resulting from burn injuries, especially in the pediatric population through providing highly vascularized adjacent local tissues with optimal hair density, color matching, texture, and hair-bearing characteristics. The aim of this study was to evaluate the efficacy of anterior capsulotomy and basal capsulectomy adherent to expanded scalp flap during alopecia reconstruction with scalp expansion in pediatric burned patients. METHODS: The study was conducted on 127 patients with an age range of 5 to 19 years who presented with postburn alopecia accompanied by hairline loss. The patients were divided into 2 groups: group I consisted of 58 patients who were operated on using conventional technique, and group II consisted of 69 patients who were operated using modified technique including basal capsulectomy on the skull side and anterior capsulotomy on the expanded scalp flap. RESULTS: The Hairdex, a validated questionnaire of Hair-Specific Health-Related Quality of Life measures, showed that percentage of satisfaction concerning outcomes was 91.50%, psychological well-being was 95%, and self-confidence was 84.30% in group II, compared with 63%, 55.70%, and 66.20%, respectively, in group I. This significant values had a great positive effect on patient satisfaction, changing child's behavior and self-confidence. CONCLUSION: Although physiological background of tissue expansion is the same, proper flap design with anterior capsulotomy on flap undersurface and basal capsulectomy on the skull side improve results of the traditional method significantly and minimize the complication rate. These surgical modifications provide maximum benefits from expanded tissue, with restoration of the hairline and a uniform hair direction. LEVEL OF EVIDENCE: Level III, case-control study.

Esthetic restoration of progressive hemifacial atrophy (Parry-Romberg disease) by free fat grafting using computerized-assisted mapping.

BACKGROUND: This study aimed to evaluate the use of fat grafting enriched with platelet-rich plasma through a computerized-assisted mapping for esthetic restoration in progressive hemifacial atrophy (Parry-Romberg disease). METHODS: This prospective study was conducted on 53 patients presented by Parry-Romberg disease and was corrected by facial fat grafting (FFG) enriched with platelet-rich plasma (PRP). A computerized software program was used to design a detailed map to achieve clinical symmetry with fat grafting application, as the anatomical subunits direct 3-dimensional volumetric symmetric, and compartments direct isolated recipient-specific grafting. Also, volumetric asymmetry was assessed through outlines of facial contour, projection, and proportions for both sides and comparing the mirror image of unaffected side as a template. RESULTS: Objective ultrasound and photogrammetric measurements showed a significant improvement in facial symmetry postoperatively compared to preoperative (P < 0.05), with no significant differences between 12 and 18 months after surgery. The FACE-Q score regarding comparison before surgery and 18 months after surgery showed a statistically significant improvement in all modules (P < 0.001) with overall satisfaction concerning outcome of 82.7 ± 0.8. CONCLUSION: Enriched fat grafting with platelet-rich plasma (PRP) is a good alternative to reconstruct soft tissue defects for patients with progressive hemifacial atrophy (Parry-Romberg disease) with a minimally invasive approach and low complications. It provides volumetric replacement, enhancement of skin texture, and improvement of hyperpigmentation with restoration of facial contour for an esthetic pleasing appearance. Isolated replacement in accordance with the anatomical facial subunits and fat compartments allows three-dimensional reconstruction and maximizes fat retention.

Programmed death-ligand 1 (PD-L1) polymorphisms as predictive biomarkers for the development of liver cirrhosis and hepatocellular carcinoma in HCV Egyptian patients.

BACKGROUND: Considering the immune evasion role of programmed death-ligand 1 (PD-L1) in cancer development, its genomic variations might be closely associated with disease development and cancer risks. Accordingly, this study was performed to investigate how the PD-L1 gene polymorphisms affect the susceptibility to hepatitis C virus (HCV)-induced liver cirrhosis and cancer development in the Egyptian population. METHODOLOGY: Two single nucleotide polymorphisms of the PD-L1 gene; rs2297136 (A > G) and rs4143815 (C > G), were studied in 50 HCV, 51 liver cirrhosis, and 52 hepatocellular carcinoma (HCC) patients as well as 50 healthy subjects using real-time PCR. RESULTS: The frequencies of PD-L1 rs2297136 AA and rs4143815 GG genotypes were significantly higher in the liver cirrhosis than the control and HCV groups. The rs4143815 CG and GG genotypes were linked to a higher risk of developing HCC and were positively associated with the clinicopathological features of HCC. CONCLUSIONS: The PD-L1 rs2297136 AA and rs4143815 GG genotypes increase the susceptibility to liver cirrhosis. The rs4143815 CG and GG genotypes are positively associated with HCC risk and its clinicopathological characteristics. Therefore, HCV patients carrying the PD-L1 rs4143815 G-allele should be followed up on a regular basis to allow for early HCC management.

Ophthalmic Complications Following Facial Autologous Fat Graft Injection: A Systematic Review and Meta-Analysis.

INTRODUCTION: With the recent increase in interest in using autologous fat (AF) filler injections to enhance aesthetic facial appearance, there is a noticeable increase in the complications such as vascular compromise and blindness. This systematic review and meta-analysis aimed to understand the symptomatology of ophthalmic complications related to AF facial injections for cosmetic purposes, their underlying causes, management options, and the final clinical outcomes. METHODS: This review was conducted according to the International Prospective Register of Systematic Reviews (PROSPERO) guidelines. In November 2021, we performed a systematic review of available literature using the following electronic databases: Cochrane, MEDLINE, and EMBASE. Our search was limited to the published studies between 2000 and 2021. RESULTS: A total of 1052 publications and 34 articles published were included. Twenty case reports, two case series, one prospective cohort study, and eleven retrospective studies were evaluated. The forehead was the most common single injection site (n = 196, 55.36%). The most common initial symptom was periorbital swelling (92.7%). The pooled prevalence of ophthalmic artery occlusion was 50.4% out of all AF injection-related complications. Regarding the management, most patients were managed conservatively (n = 278, 51.38%). Complete improvement was observed among 423 patients (80.57%). CONCLUSION: Autologous facial fat injection is a minimally invasive procedure with a favorable safety profile in cosmetic applications. However, the common use of these injections in aesthetic surgery has resulted in a concomitant increase in devastating consequences, such as blindness. Therefore, a firm understanding of the potential complications of such interventions is essential. LEVEL OF EVIDENCE III: This journal requires that authors assign a level of evidence to each article.

Exposure of Skin Homografts from Related Living Donors to Radiotherapy and Its Effects on Acute Rejection and Wound Healing in Children with Deep Burns: A Randomized Controlled Trial.

Background The ideal skin substitute should be more similar to normal skin function while causing fewer reactions. The purpose of this study was to assess the effect of radiotherapy on minimizing acute rejection and enhancing wound healing in children with deep burns. Patients and Methods A prospective randomized control study included 34 children admitted to the burn unit with deep burns under the age of 12 years. Through the tomotherapy device, a skin homograft from a related living donor was exposed to a local dose of radiotherapy of 500 centigray (cGy). It was immediately used for coverage of the prepared bed after the irradiation was completed. Results The mean values of the laboratory parameters (ESR, CRP, IL-6, and TNF) for all burn patients in the study showed a significant difference, with p < 0.001. The mean ± standard deviation (SD) of the time from homograft coverage to the appearance of rejection was 9.62 ± 1.45 in group 1 and 14.35 ± 2.8 in group 2, with p < 0.001 (highly significant difference), indicating that exposure to radiotherapy can reduce graft rejection. Conclusions The exposure of skin homografts from related living donors to a local low dose of radiotherapy can reduce a graft's ability to initiate inflammatory and immunological reactions, thereby minimizing rejection of a graft and enhancing epithelialization in children with deep second- and third-degree burns.
