Objective: This study aims at spotlighting different lines of management of aggressive vertebral hemangioma (VH) through a retrospective analysis of single center experience. Methods: Patients diagnosed with aggressive VHs in a tertiary referral center were reviewed from 2014 through 2024. Data of patients who met the inclusion criteria were analyzed. Patients of all ages, both sexes, and all varieties of clinical presentation were included, only patients who underwent at least one intervention were included. Results: The study included nine patients, comprising six females and three males, with a mean age of 29.3 years (ranging from 14 to 46). Six patients underwent Trans-arterial embolization (TAE), of whom five underwent further surgical procedures, while one patient found TAE to be sufficient as a stand-alone management technique. Eight patients underwent surgical management, five of whom were pre-operatively embolized. Conclusions Aggressive VHs are rare, and their management is challenging. Most cases require a multi-modal management, especially when presented with neurological deficit. Pre-operative embolization and/or vertebroplasty are safe and useful tools to decrease intra-operative bleeding of such a vascular pathology in cases undergoing open surgical procedures.

Purpose: This study was performed to introduce, evaluate, and compare various novel assessment protocols designed for straightforward, reliable, and reproducible measurement of alveolar bone levels. These protocols are intended for standardized periodontal assessment and follow-up, utilizing cone-beam computed tomography (CBCT) images and manipulation of Digital Imaging and Communications in Medicine (DICOM) viewer software. Materials and Methods: Two experienced oral and maxillofacial radiologists developed 5 distinct radiographic measurement protocols. These techniques were established to assess the alveolar bone level of a periodontally affected upper central incisor using a method that is consistently repeatable across observers. Two additional assessors, blindedto the details of the study, independently applied the protocols to retrieved DICOM files that met the eligibility criteria.A scoring system with 3 subscores was created and used to compare the protocols. Results: Statistically excellent inter-observer reliability was observed for all protocols, other than protocol 1, which demonstrated moderate reliability. The average discrepancy between measurements taken by the 2 observers was 1.2 mm for protocol 1, 0.81 mm for protocol 2, and less than 0.5 mm for the remaining 3 protocols. All approaches except protocol 4 were straightforward to apply. Conclusion This study introduces multiple reliable protocols for the evaluation of periodontal bone levels that ensureconsistency across observers. Based on the findings, the double axial lines and incisocrestal distance protocols are recommended. These new assessment approaches, along with any future modifications, may be useful in periodontal assessment, dental implant follow-up, orthodontic evaluation, research, and artificial intelligence model generation.

Background: s/Aims: No reports to compare incisional hernia (IH) incidence between laparoscopic and open colorectal liver metastases (CRLM) resections have previously been made. This is the first comparative study. Methods: Single-center retrospective review of patients who underwent CRLM surgery between January 2011 and December 2018.IH relating to liver surgery was confirmed by computed tomography. Patients were divided into laparoscopic liver resection (LLR) and open liver resection (OLR) groups. Data collection included age, sex, presence of diabetes mellitus, steroid intake, history of previous hernia or liver resection, subcutaneous and peri-renal fat thickness, preoperative creatinine and albumin, American Society of Anesthesiologists (ASA) score, major liver resection, surgical site infection, synchronous presentation, and preoperative chemotherapy. Results: Two hundred and forty-seven patients were included with a mean follow-up period of 41 ± 29 months (mean ± standard deviation). Eighty seven (35%) patients had LLR and 160 patients had OLR. No significant difference in the incidence of IH between LLR and OLR was found at 1 and 3 years, respectively ([10%, 19%] vs. [10%, 19%], p = 0.95). On multivariate analysis, previous hernia history (hazard ratio [HR], 2.22; 95% confidence interval [CI], 1.56–4.86) and subcutaneous fat thickness (HR, 2.22; 95% CI, 1.19–4.13) were independent risk factors. Length of hospital stay was shorter in LLR (6 ± 4 days vs. 10 ± 8 days, p < 0.001), in comparison to OLR. Conclusions In CRLM, no difference in the incidence of IH between LLR and OLR was found. Previous hernia and subcutaneous fat thickness were risk factors. Further studies are needed to assess modifiable risk factors to develop IH in LLR.

Background: and Purpose Repetitive transcranial magnetic stimulation (rTMS) of the cerebellar hemisphere represents a new option in treating essential tremor (ET) patients. We aimed to determine the efficacy of cerebellar rTMS in treating ET using different protocols regarding the number of sessions, exposure duration, and follow-up duration. Methods: A randomized sham-controlled trial was conducted, in which 45 recruit patients were randomly allocated to 2 groups. The first (active group) comprised 23 patients who were exposed to 12 sessions of active rTMS with 900 pulses of 1-Hz rTMS at 90% of the resting motor threshold daily on each side of the cerebellar hemispheres over 4 weeks. The second group (sham group) comprised 22 patients who were exposed to 12 sessions of sham rTMS. Both groups were reassessed at baseline and after 1 day, 1 month, 2 months, and 3 months using the Fahn-Tolosa-Marin tremor-rating scale (FTM). Results: Demographic characteristics did no differ between the two groups. There were significant reductions both in FTM subscores A and B and in the FTM total score in the active-rTMS group during the period of assessment and after 3 months (p=0.031 and 0.011, respectively).However, subscore C did not change significantly from baseline when assessed at 2 and 3 months (p=0.073 and 0.236, respectively). Furthermore, the global assessment score was significantly higher in the active-rTMS group (p>0.001). Conclusions Low-frequency rTMS over the cerebellar cortex for 1 month showed relative safety and long-lasting efficacy in patients with ET. Further large-sample clinical trials are needed that include different sites of stimulation and longer follow-ups.

Objective: Pain is one of the most common nonmotor symptoms in Parkinson’s disease (PD), with variable characteristics among populations. This multicenter Egyptian study aimed to translate and validate the King’s Parkinson’s Disease Pain Scale (KPPS) and Questionnaire (KPPQ) into Arabic versions and to investigate the pain characteristics in Egyptian people with PD (PWP). Methods: A total of 192 PWP and 100 sex- and age-matched controls were evaluated by the KPPS-Arabic and KPPQ-Arabic. Both tools were assessed for test–retest reliability, floor or ceiling effects, construct validity and convert validity. PWP were also assessed by the Movement Disorders Society-Unified Parkinson’s Disease Rating Scale (MDS-UPDRS), Hoehn and Yahr scale (H&Y), Non-Motor Symptom Scale (NMSS), PD Questionnaire-39, and Non-Motor Fluctuation Assessment (NoMoFA). Results: The KPPS-Arabic and KPPQ-Arabic showed inter- and intrarater consistency and high validity, with an acceptable ceiling effect. A total of 188 PWP (97.9%) reported at least 1 type of pain (p < 0.001). The severity and prevalence of all pain domains in the KPPS-Arabic were significantly higher among PWP than among controls (p < 0.001). Fluctuation-related and musculoskeletal pains were the most common (81.3% and 80.7%, respectively). In the PD group, the total and domains of KPPS-Arabic were significantly correlated to the MDS-UPDRS total score and the scores of Parts I, II, III, postural instability gait disorder, axial, and H&Y but not with age or age of onset. The predictors of KPPS-Arabic scores included the total MDS-UPDRS, the part III-OFF, disease duration, the total NMSS, and the NoMoFA scores. Conclusion The current multicenter study provided validated Arabic versions of the KPPS and KPPQ, which exhibited high reliability and validity, and demonstrated a high prevalence and severity of pain within Egyptian PWP and characterized its determinants.

Objective: This study examined the risk factors and survival outcomes of dogs infected with CPV-2. Molecular characterization of CPV-2 genotypes circulating in Egypt was performed to determine the evolution of CPV-2 nationally and globally. Methods: An age-matched case-control study was conducted on 47 control and 47 CPVinfected dogs. Conditional logistic regression analysis examined the association between the potential risk factors and CPE in dogs. Survival analysis was performed to determine the survival pattern of the infected dogs. Thirteen fecal samples from infected dogs were collected to confirm the CPV genotype by CPV-2 VP2 gene sequencing, assembly of nucleotide sequences, and phylogenic analysis. Results: Unvaccinated and roamer dogs had eight and 2.3 times higher risks of CPV infection than vaccinated dogs and non-roamer dogs, respectively. The risk of death from CPE was high among dogs without routine visits to veterinary clinics and among non-roamer dogs.Molecular characterization of CPV-2 confirmed its genotype identity and relationship with the CPV-2 c and b clade types. Conclusions and Relevance: This study highlights the potential factors for CPE control, especially vaccination and preventing dogs from roaming freely outside houses. Isolated CPV genotypes are closely related to southern Asian genotypes, suggesting a substantial opportunity for global transmission.

Aims: This study was aimed to produce biodegradable cellulose acetate films impregnated with bacteriocin-like inhibitory substances to be used in food packaging. Methodology and results: Bacterial isolates were isolated from different sources and tested for their antimicrobial activity by agar well diffusion assay. The isolate that showed the highest antimicrobial activity against Staphylococcus aureus ATCC 29213, Escherichia coli ATCC 51659, Pseudomonas aeruginosa MG847103 and Streptococcus mutans ATCC 25175 was identified as Lactiplantibacillus plantarum strain N1 (OM019104) based on 16S rRNA based method of identification. The extracted bacteriocin-like inhibitory substances were partially purified with acetone precipitation and SP-Sephroase cation exchange chromatography. There was no change in the antimicrobial activity after treatment with the catalase enzyme, but there was a total loss in the activity after treatment with proteolytic enzymes. The obtained bacteriocin-like inhibitory substances showed pH stability over a wide range of pH values and thermal stability as it recovered 95% of its antimicrobial activity even after autoclaving for 15 min. Different concentrations of cellulose acetate (3 to 12%) were tested to develop the active antimicrobial films. The most flexible concentrations for food packaging were prepared and impregnated with partially purified bacteriocin-like inhibitory substances. The prepared films showed promising antimicrobial activity against S. aureus. Conclusion, significance and impact of study This study highlights the usage of active packaging in food preservation. Cellulose acetate films activated with the partially purified bacteriocin-like inhibitory substances have anti-staphylococcal activity, which can potentially be used in food packaging to prolong the shelf-life of perishable foo
