RESUMEN
INTRODUCTION: In Egypt, there is a paucity of new data regarding awareness of HIV/AIDS among physicians. This study aimed to assess the level of awareness, attitude, practice, and knowledge of a sample of Egyptian physicians regarding HIV regarding natural history, epidemiology, and virology, method of transmission, clinical manifestations, diagnosis, prevention, and management. METHODOLOGY: Sixty-eight Egyptian physicians were enrolled in an observational analytic multicenter cross-sectional KAP study in Egyptian tertiary health care facilities covering different localities, including New Valley University, Assiut University, South Valley University, Helwan University, Alexandria University, Aswan University, and Al-Azhar University. RESULTS: The attitude of physicians towards the privacy of persons living with HIV, was the one with the highest percentage 85.3%. On the other hand, respondents think that only 25% of physicians do not stigmatize HIV patients. Moreover, only 25% of the study group do not stigmatize persons living with HIV. The highest proportion of favorable practice was 39.7% and the lowest was 17.6%. With regard to their knowledge about HIV, the lowest proportion of correct answers to a question was 4.4%, and the highest proportion was 92.6%. Most of the enrolled physicians were found to have a moderate knowledge score, 49/68 (72%). There was a significant difference between different specialties regarding knowledge scores. CONCLUSIONS: There are some knowledge gaps among a sample of Egyptian physicians with regard to HIV/AIDS. In addition, Egyptian physicians may have a moderate degree of undesirable attitude and practice toward HIV/AIDS.

Aim: ST-elevation myocardial infarction (STEMI) patients suffer higher mortality and adverse outcomes linked to endothelial dysfunction (ED). Methods: 43 patients were randomized to pentoxifylline (PTX) 400 mg thrice daily (n = 22) or placebo (n = 21). Soluble vascular cell adhesion molecule-1, malondialdehyde, interleukin-1 (IL-1), interleukin-6 (IL-6), high-sensitivity C-reactive protein (hs-CRP) and tumor necrosis factor-α (TNF-α) were assessed at baseline and 2 months. Results: After 2 months, no significant difference was observed in markers' levels between the 2 groups. However, a within-group comparison revealed a statistically significant change in hs-CRP in the PTX group (10.057 (9.779-10.331) versus 9.721 (6.102-10.191)), p = 0.032. Conclusion: PTX for 2 months in STEMI patients was safe and well-tolerated but had no significant detectable effect on ED, oxidative stress or inflammatory markers. Clinical Trial Registration: NCT04367935 (ClinicalTrials.gov).
This study examined the effect and the safety of a drug called pentoxifylline in patients who have recently had a heart attack. Pentoxifylline can possibly reduce inflammation and is used for patients with blood flow issues. The study involved 43 participants, 22 receiving pentoxifylline and 21 receiving a placebo for 2 months. We measured different markers related to inflammation and heart health before and after. Overall, there was no significant difference between the groups, but patients who received pentoxifylline experienced less inflammation according to only one of the markers measured. This study concluded that the prescription of pentoxifylline after a heart attack is safe, well-tolerated and without notable side effects. Still, we recommend larger and longer studies to be sure of its effect.
RESUMEN
Numerous classification and regression problems have extensively used Support Vector Machines (SVMs). However, the SVM approach is less practical for large datasets because of its processing cost. This is primarily due to the requirement of optimizing a quadratic programming problem to determine the decision boundary during training. As a result, methods for selecting data instances that have a better likelihood of being chosen as support vectors by the SVM algorithm have been developed to help minimize the bulk of training data. This paper presents a density-based method, called Density-based Border Identification (DBI), in addition to four different variations of the method, for the lessening of the SVM training data through the extraction of a layer of border instances. For higher-dimensional datasets, the extraction is performed on lower-dimensional embeddings obtained by Uniform Manifold Approximation and Projection (UMAP), and the resulting subset can be repetitively used for SVM training in higher dimensions. Experimental findings on different datasets, such as Banana, USPS, and Adult9a, have shown that the best-performing variations of the proposed method effectively reduced the size of the training data and achieved acceptable training and prediction speedups while maintaining an adequate classification accuracy compared to training on the original dataset. These results, as well as comparisons to a selection of related state-of-the-art methods from the literature, such as Border Point extraction based on Locality-Sensitive Hashing (BPLSH), Clustering-Based Convex Hull (CBCH), and Shell Extraction (SE), suggest that our proposed methods are effective and potentially useful.

BACKGROUND: The wound-healing process in diabetic foot is affected by pro and anti-inflammatory markers, and any disruption in the inflammatory reaction interferes with tissue homeostasis, leading to chronic non-wound healing. AIM: This study aimed to determine the diagnostic value and effect of CRP, IL-6, TNF, and HbA1c on initiation the and progression of diabetic foot ulcers. METHOD: ELISA was used to quantify IL-6, TNF, CRP, and HbA1c in 205 patients with diabetes, and 105 were diabetic foot free. The prevalence and progression of diabetic foot were also evaluated. The area under the curve (AUC) was calculated using the receiver operating characteristic (ROC) curve to analyze the predictive values. Forward stepwise logistic regression analysis was used to compute the odds ratio (OR) and the corresponding 95% confidence intervals (CIs). RESULTS: CRP, IL-6, and FBS were found to be significant predictors of diabetic foot (OR=1.717, 95% CI=1.250-2.358, P=0.001; OR=1.434, 95% CI=1.142-1.802, P=0.002; and OR=1.040, 95% CI=1.002-1.080, P=0.037), respectively. The AUCs for CRP, IL-6, and HbA1c in predicting diabetic foot were 0.839, 0.728, and 0.834, respectively, demonstrating a good predictive value for each diagnostic marker. CONCLUSION: The current study demonstrated that IL-6, CRP, and HbA1c may be useful biomarkers to indicate diabetic foot progression. Furthermore, our findings showed a substantial relationship between CRP and HbA1c in individuals with diabetic foot conditions.

Schistosomiasis is the second most prevailing parasitic disease worldwide. Although praziquantel is considered an effective drug in the treatment against schistosomiasis to some extent, there is an emerging drug resistance that widely recorded. Therefore, there is an urgent need to develop effective and safe anti-schistosomal drugs. In this study, Cornulaca monacantha (C. monacantha), a sub-saharan plant, was extracted using aqueous ethanol and characterized by High-Performance Liquid Chromatography (HPLC). Major constituents of the extract are belonging to flavonoids, tannins and phenolic glycosides. Worms' viability and surface morphology of Schistosoma mansoni (S. mansoni) adult worms treated with the extract were assessed using in vitro viability assay, Scanning Electron Microscopy (SEM), and histological examination. The extract (80-350 µg/ml) reduced viability percentage of worms by 40-60% and caused degeneration of both oral and ventral suckers, tegumental, sub-tegumental and muscular damage. Molecular docking approach was utilized to assess the binding affinities of the extracted compounds with S. mansoni alpha-carbonic anhydrase (SmCA), an essential tegument protein. Pharmacokinetic analysis using SwissADME showed that 7 compounds have high drug similarity. This study confirms the in vitro schistomicidal activity of C. monacantha extract against S. mansoni adult worms and suggests potential SmCA inhibition.

Background: One of the limitations of the right radial access approach is complex vessel anatomy, such as subclavian tortuosity. Several clinical predictors have been proposed for tortuosities, such as older age, female sex and hypertension. In this study, we hypothesised that chest radiography would add predictive value to the traditional predictors. Methods: This prospective blinded study included patients who underwent transradial access coronary angiography. They were classified into four groups according to difficulty: Group I, Group II, Group III and Group IV. Different groups were compared according to clinical and radiographic characteristics. Results: The study included 108 patients (54, 27, 17 and 10 patients in Groups I, II, III and IV, respectively). The rate of crossover to transfemoral access was 9.26%. Age, hypertension and female sex were associated with a greater difficulty and failure rates. Regarding radiographic parameters, a higher failure rate was associated with a higher diameter of the aortic knuckle (Group IV, 4.09 ± 1.32 cm versus Groups I, II and III combined, 3.26 ± 0.98 cm; p=0.015) and the width of the mediastinum (Group IV, 8.96 ± 2.88 cm versus Groups I, II and III combined, 7.28 ± 1.78 cm; p=0.009). The cut-off value for prominent aortic knuckle was 3.55 cm (sensitivity 70% and specificity 67.35%) and the width of mediastinum was 6.59 cm (sensitivity 90% and specificity 42.86%). Conclusion: Radiographic prominent aortic knuckle and wide mediastinum are valuable clinical parameters and useful predictors for transradial access failure caused by tortuosity of the right subclavian/brachiocephalic arteries or aorta.
RESUMEN
OBJECTIVE: The purpose of this study was to investigate the effect of instrument-assisted soft tissue mobilization (IASTM) versus myofascial release therapy (MRT) on college students with chronic mechanical neck pain (CMNP). METHODS: Thirty-three college students with a mean age of 21.33 ± 0.98 involved in distance learning due to the Corona Virus 2019 (COVID-19) restriction were randomized to receive either IASTM on the upper trapezius and levator scapulae muscles or MRT. Researchers measured their pain with a visual analog scale (VAS), function with neck disability index (NDI), and pain pressure threshold (PPT) with a pressure algometer. The subjects received eight therapy sessions over four weeks and outcome measures were assessed pre and post-intervention. The study was registered as a clinical trial on clinicaltrials.gov (registration number: NCT05213871). RESULT: Unpaired t-test showed no statistical significance between the two groups post-intervention regarding improvement in pain, function, and PPT (p > 0.05). CONCLUSION: This study showed insignificant differences between groups. However, we did not use a control group, indicating that the improvement in outcomes may not have been caused by the intervention. STUDY DESIGN: Quasi-experimental two groups pre-posttest clinical trial. LEVEL OF EVIDENCE: Therapy, level 2b.

BACKGROUND: Flatfoot is a musculoskeletal problem associated with dysfunctional active and passive supporting structures of the normal foot curvature. Strengthening of the intrinsic foot muscles or using shoe orthosis are recommend treatment approaches. However, investigating the effect of combining both approaches is still warranted. AIM: To examine the effect of applying short foot exercises (SFE) combined with shoe insole versus shoe insole alone on foot pressure measures, pain, function and navicular drop in individuals with symptomatic flexible flatfoot. DESIGN: Prospective, active control, parallel-group, assessor-blinded, randomized controlled trial and intention-to-treat analysis. SETTING: Outpatient physical therapy clinic of a university teaching hospital. POPULATION: Forty participants with symptomatic flexible flatfoot. METHODS: A six-week treatment protocol of SFE (three sets of 10 repetitions a day) in addition to shoe insole (eight hours a day) (experimental group, N.=20) or shoe insole only (eight hours a day) (control group, N.=20). Clinic visits were made at baseline and every two weeks for monitoring and follow-up. The static and dynamic foot area, force and pressure measures, pain, lower extremity function, and navicular drop were assessed at baseline and postintervention. RESULTS: Forty participants joined the study and 37 (92.5%) completed the six-week intervention period. Foot pressure, pain and function showed a significant interaction (P=0.02 - <0.001) and time (P<0.001) effects with a non-significant group effect in favor of the experimental group. Post-hoc analysis revealed that the experimental group had lesser pain (P=0.002) and better function (P=0.03) than the control group at six weeks. Navicular drop decreased equally in both groups. CONCLUSIONS: Implementation of shoe insole and SFE for six weeks improved pain and function and altered foot pressure distribution greater than shoe insole alone in patients with symptomatic flatfoot. CLINICAL REHABILITATION IMPACT: Wearing shoe insole is an easy, but passive, treatment approach for a flatfoot problem. This study provided evidence regarding the added benefit of SFE. It is recommended that rehabilitation practitioners implement a comprehensive treatment protocol including both shoe insole and SFE for at least six weeks to achieve better results for their flatfoot patients.

BACKGROUND: Vaginal atrophy is common after menopause and is often linked to sexual dysfunction, particularly dyspareunia. AIM: The study aimed to investigate the effect of intravaginally applied oxytocin on expressions of vaginal atrophy. METHODS: Fifty postmenopausal women aged 47 to 66 years with vaginal atrophy participated in this double-blinded placebo-controlled study. The women were randomized to intravaginal treatment with either gel with 600 IU/mL of oxytocin (oxytocin group) or gel alone (control group) once daily for 2 weeks. The gel consisted of hypromellose, pH 3.8 (Vagovital). OUTCOMES: The color of the vaginal mucosa, the vaginal pH, and the cytology of vaginal epithelial cells were investigated before and after treatment. RESULTS: The color of the vaginal mucosa shifted from pale to red in all 25 patients treated with oxytocin but only in 4 patients in the control group (P < .001). There was a significant decrease in intravaginal pH in the oxytocin group and the control group, with the delta value being significantly greater in the oxytocin group than in the control group (P < .001). The vaginal maturation index increased significantly (P < .001) in the oxytocin group but not in the control group. CLINICAL IMPLICATIONS: Topical oxytocin gel offers an effective solution to the sexual dysfunction that is related to vaginal atrophy after menopause. STRENGTHS AND LIMITATIONS: Strengths include studying different outcomes of applying the oxytocin gel for vaginal atrophy. Limitations include the small-scale population with a relatively short duration of treatment (2 weeks). CONCLUSION: Intravaginal treatment with a gel containing 600 IU/mL of oxytocin effectively counteracts physical expressions of vaginal atrophy. TRIAL REGISTRATION: ClinicalTrials.gov (NCT05275270; https://clinicaltrials.gov/ct2/show/NCT05275270).

Thrombus is the main finding in most patients with acute coronary syndrome (ACS), the type of which potentially impacts the end result of the interventional procedure in terms of no reflow and edge dissection. Optical coherence tomography (OCT) is considered a precise intra-vascular tool to image thrombi and characterise its properties. We aimed to study the impact of thrombus type, as defined by OCT, on procedural outcome in ACS patients. In this retrospective study we enrolled 100 patients who were treated by percutaneous coronary intervention (PCI) with the guidance of OCT. We recorded demographic and clinical data of the whole studied cohort. Angiographic details and procedural data were noted. Baseline OCT study was performed before intervention and repeated post- intervention. Plaque characterisation was identified, and thrombi were defined as red or white thrombi. Acute angiographic outcome was defined with special emphasis on no reflow. Male patients and ST-elevation myocardial infarction (STEMI) patients more often had white thrombi (58.1% and 71.2%, respectively). Cases with red thrombi had longer pain duration, which was statistically significant. Edge dissection was more frequent with red thrombus, 44.7% versus 32.1% with white thrombus, but the difference is not statistically significant, while 17% of patients with white thrombi were complicated by no-reflow phenomenon versus only 4.3% in patients with red thrombi, and this difference was statistically significant. In conculsion, OCT-guided PCI is feasible and safe in ACS settings. OCT- guided intra-procedural differentiation of thrombus type is potentially beneficial in predicting acute procedural outcome.
RESUMEN
Background: Colorectal cancer (CRC) is the fifth most diagnosed cancer in Sub-Saharan Africa. In Kenya, CRC incidence rates tripled from 1997 to 2017. In the Moi Teaching and Referral Hospital, Moi University, there has been an increase in CRC cases, notably for younger patients. A suggested pathobiology for this increase is gut microbiome dysbiosis. Since, for the Kenyan CRC patient population, microbiome studies are rare, there is a need for a better understanding of how microbiome dysbiosis influences CRC epidemiology in Kenya. In this single-center study, the focus was on profiling the gut microbiome of Kenyan CRC patients and healthy volunteers and evaluating associations between microbiome profiles and the age of CRC patients. Methods: The gut mucosa-associated microbiome of 18 CRC patients and 18 healthy controls were determined by 16S rRNA sequencing and analyzed for alpha and beta diversity, differential abundance, and microbial metabolic profiling. Results: Alpha diversity metrics showed no significant differences, but beta diversity metrics showed dissimilarities in the microbial communities between CRC patients and healthy controls. The most underrepresented species in the CRC group were Prevotella copri (P. copri) and Faecalibacterium prausnitzii (F. prausnitzii), although Bacteroides fragilis (B. fragilis) and Prevotella nigrescens were overrepresented (linear discriminant analysis, LDA score >2, P<0.05). Also, for CRC patients, significant metagenomic functional alterations were evident in microbial glutamate metabolic pathways (L-glutamate degradation VIII was enriched, and L-glutamate and L-glutamine biosynthesis were diminished) (P<0.05, log2 Fold Change >1). Moreover, the microbiome composition was different for patients under 40 years of age compared to older patients (LDA score >2, P<0.05). Conclusions: Microbiome and microbial metabolic profiles of CRC patients are different from those of healthy individuals. CRC microbiome dysbiosis, particularly P. copri and F. prausnitzii depletion and glutamate metabolic alterations, are evident in Kenyan CRC patients.
RESUMEN
The aim of this retrospective study is to evaluate and compare the clinical and radiological results of the use of Zero-P implant and the integrated cage-plate implant in surgical treatment of single level cervical disc disease. It includes 54 consecutive patients who underwent single level anterior cervical discectomy and fusion. The patients were divided into 2 groups. Group (A) including 28 patients operated with zero- profile implant and group (B) including 26 patients operated with integrated cage-plate implant. Mean operative time, blood loss, incidence of dysphagia and any other complications related to the procedure were recorded and compared. Patients were assessed radiologically by measuring cervical lordosis using the Cobb angle and the segmental angle. Patients were assessed clinically by the Japanese orthopedic association score and the neck disability index. These values were also compared. The mean age of the patients in group (A) was 49.5±11 years, and in group (B) it was 49.8±11.6 years. Mean blood loss and operative time in group (A) were 77.3±9.4 ml and 72.1±7.9 minutes, while in group B, they were 80.7±9.5 ml and 74.8±8.4 minutes with no statistically significant difference between both groups. There were also no statistically significant difference between both groups as regards incidence of dysphagia, clinical scores nor radiological parameters. In conclusion, both zero-profile implant and integrated cage-plate implant have comparable satisfactory clinical and radiological results in treatment of single level cervical disc diseases with little complications.

PURPOSE: Colorectal cancer (CRC) is the third most commonly diagnosed cancer worldwide and the second cause of cancer related mortality. Treatment options for patients with metastatic CRC (mCRC) expanded during the last two decades, with introduction of new chemotherapeutic and targeted agents. Egypt is a lower middle-income country; Egyptian health care system is fragmented with wide diversity in drug availability and reimbursement policies across different health care providing facilities. We report the results of consensus recommendations for treatment of patients with metastatic colorectal cancer developed by Egyptian Foundation of Medical Sciences (EFMS), aiming to harmonize clinical practice through structured expert consensus-based recommendations consistent with the national status. EFMS recommendations could be utilized in other countries with similar economic status. METHODS: EFMS recommendations were developed using a modified Delphi process, with three rounds of voting till the final recommendations were approved. A non-systematic review of literature was conducted before generating the provisional statements. Content experts were asked to vote on some recommendations in two different resource groups (restricted resources and non-restricted resources). External review board of experts from a low income and lower-middle countries voted on the applicability of EFMS recommendations in their countries. RESULTS: The current recommendations highlighted the discrepancy in health care between restricted and non-restricted resources with expected survival loss and quality of life deterioration. Access to targeted agents in first line is very limited in governmental institutions, and no access to agents approved for third line in patients who failed oxaliplatin and irinotecan containing regimens for patients treated in restricted resource settings. CONCLUSION: Management of mCRC in developing countries is a challenge. The currently available resource-stratified guidelines developed by international cancer societies represent a valuable decision-making tool, adaptation to national status in each country based on healthcare system status is required.
RESUMEN
Background: Visceral leishmaniasis (also known as Kala-azar) is a systemic parasitic infection with many clinical presentations. The present study assesses the variation in presentations among patients who attended the Tropical Diseases Teaching Hospital (TDTH) in Khartoum, Sudan. Methods: This analytical cross-sectional, hospital-based study was conducted at the TDTH between November 2019 and September 2020. Medical records of patients who presented at the TDTH were reviewed using a structured data extraction checklist. The Chi-square test was used to determine the associations between sociodemographic and clinical presentations of patients. P-value < 0.05 was considered as statistically significant. Results: Out of 195 patients, 79.5% were male and 48.2% were <31 years old. Fever was the main clinical presentation (90.2%) while 53.3% presented with weight loss and 72.3% and 39% presented, respectively, with splenomegaly and hepatomegaly. HIV was detected in 4.6% of the patients. RK39 was the main diagnostic test. We found a significant association between the abdominal distention and the age of the patients (P < 0.05) age groups 1120 and 4150 years were more likely to present with abdominal distention than other age groups. Conclusion: There is no exact clinical presentation or routine laboratory findings that are pathognomonic for visceral leishmaniasis; therefore, it should be considered in the differential diagnosis of any patient with fever, weight loss, and abdominal distention, and among patients with HIV.

Caseous lymphadenitis (CLA) or pseudotuberculosis is a chronic zoonotic bacterial disease caused by Corynebacterium pseudotuberculosis, which affects livestock and humans. This study aimed to describe the pathology, bacteriology and confirm the identity of the pathogen by 16S rRNA gene sequencing in Camelus dromedarius. A total of 12 camels with suspected CLA in three regions of Abu Dhabi Emirate (Abu Dhabi, Al Ain and Al Dhafra), United Arab Emirate (UAE) were subjected to clinical and postmortem examinations from January 2015 to December 2020. Clinically, camels were emaciated and showed the presence of external caseous abscesses suggestive of CLA. Postmortem examination showed multiple abscesses of variable sizes with caseous material encapsulated by fibrous tissue in the liver, lungs, muscle, and lymph nodes. Following clinical and postmortem examination, blood, pus and different tissue samples were collected for subsequent analysis. Histopathological examination of all organs stained with Hematoxylin and Eosin (H&E) indicated a central caseo-necrotic core that was admixed with bacterial colonies and infiltration of chronic inflammatory cells, surrounded by a pyogenic membrane, and an outer fibrous connective tissue capsule. Bacterial culture identified the isolates of Corynebacterium pseudotuberculosis biotype ovis strain, and these isolates were shown to be sensitive to all antibiotics tested (penicillin, ampicillin, Co-trimoxazole, enrofloxacin and tetracycline). Moreover, the identity of the isolates was confirmed by partial sequencing of the 16S rRNA gene which showed a 100% identity to Corynebacterium pseudotuberculosis. Phylogenetic analysis based on 16S rRNA gene sequence clearly differentiates Corynebacterium pseudotuberculosis from other species of Corynebacterium. Briefly, this study provided the basic information for infection of Corynebacterium pseudotuberculosis in Camels and will help in controlling of this pathogen in the region.

Background: In developing countries like Egypt, the clinical workflow of stroke management is poorly established due to the lack of awareness of the stroke patients concerning their need of therapeutic intervention and the poor identification of facilities equipped to treat stroke. Hence, establishing a stroke system of care in developing countries that can efficiently and rapidly triage patients to the appropriate reperfusion therapy center is imperative to improving stroke management and outcomes. Aims: To evaluate a pilot experience in stroke hospital identification and expediting decision-making in AIS treatment through the Alexandria stroke network and Egyptian Stroke Network (ESN)-app. Methods: Between 2017 and 2019, seven hospitals registered themselves on the AS-Network as pilot hospitals. The ESN-application was used to detect stroke type, tele-connect stroke teams and hospitals, track triage of patients to equipped facility in real time, and streamline stroke workflow. The quality of and time required for stroke management were compared between 84 patients with acute ischemic stroke (AIS) whose treatment involved the ESN-app and 276 patients whose treatment did not. Results: During this pilot study, 360 AIS cases received reperfusion therapy, 84 of which were indicated by the ESN-app. The use of the application was associated with the significant drop in time metrics for the reperfusion AIS-patients (door-in-door-out time; 56 ± 34 min vs. 96 ± 45 min, door-to-groin puncture time; 50 ± 7 min vs. 120 ± 25 min, door-to-needle time; 55 ± 12 min vs. 78 ± 16 min with p < 0.0001). Its use was also associated with higher rates of excellent outcomes at the 90-day follow-up (without ESN-app vs. with ESN-app, 67.9 vs. 47.1%, p = 0.001) but no difference in 90-day mortality or symptomatic intracerebral hemorrhage (without ESN-app vs. with ESN-app, 9.5 vs. 11.2% and 4.8 vs. 5.1%, p > 0.05). Conclusion: Our pilot experience demonstrated that the use of the ESN-app expedited the stroke treatment workflow and facilitated tele-connection between registered stroke facilities. Additionally, its use might be associated with achieving higher rates of excellent outcomes at 90 days, where a larger scale study is needed for more confirmation.
RESUMEN
BACKGROUND: The demand for abdominoplasty procedures has increased in surgical centres as a result of patient preference and economic concerns. The International Society of Aesthetic Plastic Surgery (ISAPS) published the Facility Accreditation Guideline on 22 October 2018. It is a list of recommendations that aim to reduce the incidence of complications and increase safety standards. OBJECTIVES: The objective of this work was to detect the effects of the ISAPS guidelines on the morbidity associated with abdominoplasty procedures in day care surgical centres. METHODS: The authors performed a retrospective study. Data regarding complications of abdominoplasty were collected from medical records of the last 350 cases of abdominoplasty performed in December 2018. The complications and their incidences were compared with similar previously published data of abdominoplasty operations performed by other authors and in surgical centres before initiation of the ISAPS Facility Accreditation Guideline. RESULTS: In all cases, we achieved a significant reduction in skin and adipose tissue with improvement in body shape. The incidence of major and minor post-operative complications was lower than that reported in other literature. CONCLUSIONS: This report shows that abdominoplasty is a safe procedure with low complication rates, which are even lower when the ISAPS Facility Accreditation Guideline is followed together with national, regional, state and other legal requirements. LEVEL OF EVIDENCE IV: This journal requires that authors assign a level of evidence to each article.

BACKGROUND: Approaching ambient cistern lesions is still a challenge because of deep location and related white matter tracts (WMTs) and neural structures. OBJECTIVE: To investigate the white matter anatomy in the course of 3 types of transtemporal-transchoroidal fissure approaches (TTcFA) to ambient cistern by using fiber dissection technique with translumination and magnetic resonance imaging fiber tractography. METHODS: Eight formalin-fixed cerebral hemispheres were dissected on surgical corridor from the temporal cortex to the ambient cistern by using Klingler's method. The trans-middle temporal gyrus, trans-inferior temporal sulcus (TITS), and trans-inferior temporal gyrus (TITG) approaches were evaluated. WMTs that were identified during dissection were then reconstructed on the Human Connectome Project 1021 individual template for validation. RESULTS: The trans-middle gyrus approach interrupted the U fibers, arcuate fasciculus (AF), the ventral segment of inferior frontoocipital fasciculus (IFOF), the temporal extensions of the anterior commissure (AC) posterior crura, the tapetum (Tp) fibers, and the anterior loop of the optic radiation (OR). The TITS approach interrupted U fibers, inferior longitudinal fasciculus (ILF), IFOF, and OR. The TITG approach interrupted the U fibers, ILF, and OR. The middle longitudinal fasciculus, ILF, and uncinate fasciculus (UF) were not interrupted in the trans-middle gyrus approach and the AF, UF, AC, and Tp fibers were not interrupted in the TITS/gyrus approaches. CONCLUSION: Surgical planning of the ambient cistern lesions requires detailed knowledge about WMTs. Fiber dissection and tractography techniques improve the orientation during surgery and may help decrease surgical complications.
