Cost-effectiveness and Acceptance in Children and Parents of the Hall Technique: Systematic Review of Clinical Trials.

Aims: The purpose of this systematic review was to evaluate the cost-effectiveness and acceptance of children and their parents of the Hall technique (HT) for dental rehabilitation in pediatric dentistry.

Background: The approach of the HT is that of minimally invasive treatment of the dental element and is used exclusively on primary molars. Various studies in the literature point to HT as a restorative option well accepted by children and parents and quite predictable, with low retreatment rates and good cost-effectiveness for the management of primary molars with carious lesions.

Intracranial Pressure Evaluation in Swine During Full-Endoscopic Lumbar Spine Surgery.

Background: Neurological complications during full-endoscopic spine surgery (FESS) might be attributed to intracranial pressure (ICP) increase due to continuous saline infusion (CSI). Understanding CSI and ICP correlation might modify irrigation pump usage. This study aimed to evaluate invasive ICP during interlaminar FESS; correlate ICP with irrigation pump parameters (IPPs); evaluate ICP during saline outflow occlusion, commonly used to control bleeding and improve the surgeon's view; and, after durotomy, simulate accidental dural tear.

Expression of microRNAs miR-21 and miR-326 associated with HIF-1α regulation in neurospheres of glioblastoma submitted to ionizing radiation treatment.

Background: Glioblastoma is an incurable neoplasm. Its hypoxia mechanism associated with cancer stem cells (CSCs) demonstrates hypoxia-inducible factor 1α (HIF-1α) expression regulation, which is directly related to tumor malignancy. The aim of this study was to identify a possible tumor malignancy signature associated with regulation of HIF-1α by microRNAs miR-21 and miR-326 in the subpopulation of tumor stem cells which were irradiated by ion in primary culture of patients diagnosed with glioblastoma.

The Role of MicroRNA 181d as a Possible Biomarker Associated With Tumor Progression in Meningiomas.

Introduction Meningiomas are slow-growing intracranial neoplasms that originate from arachnoid meningothelial cells and represent 13-26% of intracranial tumors, thus being the most common. There are numerous technological advances available for a better understanding of the molecular pathways correlated with tumorigenesis and tumor progression of meningiomas. In this context, the role of microRNAs (miRNAs), which are non-coding RNAs (ncRNAs) consisting of 18 to 25 nucleotides whose function is the silencing of mRNA at the posttranscriptional level, has been highlighted.

Surgical Results of Selective Dorsal Rhizotomy for the Treatment of Spastic Cerebral Palsy.

Background: Selective dorsal rhizotomy (SDR) is one of the surgical alternatives for treating spasticity, especially in children with spastic diplegia secondary to cerebral palsy (CP). It is becoming increasingly used, and the results of this operation need to be further highlighted.

Aim: The main objective of this article was to present the results of such surgical procedure in a cohort of a specialized center, with a particular focus on a quantitative analysis (goniometry).

The Importance of Integrated Healthcare in the Association Between Oral Health and Awareness of Periodontitis and Diabetes in Type 2 Diabetics.

Purpose: To assess the association of various factors including education level and oral health with type 2 diabetics' awareness of periodontitis and periodontitis/diabetes relationship, and to evaluate the importance of integrated healthcare in this association. Materials and Methods: 288 type 2 diabetics were evaluated through a validated structured questionnaire about oral hygiene habits, access and attendance to dental treatment, the presence of periodontitis and previously received information of periodontitis and periodontitis/diabetes relationship. Descriptive data were explored and both simple and multiple logistic regressions were performed.

Psoas Abscess After Lumbar Facet Joint Injection: Case Report and Literature Review.

Low back pain (LBP) is a common condition. It is estimated that 84% of adults will present LBP symptoms at some point in their lives. Rarely, however, is LPB an indication of a serious medical condition, requiring further investigation.

Misfit detection in implant-supported prostheses of different compositions by periapical radiography and cone beam computed tomography: An in vitro study.

Statement Of Problem: Misfits at the implant-abutment joint (IAJ) can cause the biological and mechanical failure of implant therapy. Standard parallel periapical radiography (PERI) is the method of choice for assessing the fitting of implant-supported prostheses. Although current guidelines do not support the use of cone beam computed tomography (CBCT) solely for misfit detection, CBCT scans can also register misfits as imaging findings.

Experimental Model for Interlaminar Endoscopic Spine Procedures.

Background: Endoscopic spinal surgery is becoming quite popular, and the pursuit of a training model to improve surgeons' skills is imperative to overcome the limited availability of human cadavers. Our goal was to determine whether the porcine spine could be a representative model for learning and practicing interlaminar percutaneous endoscopic lumbar procedures (IL-PELPs).

Methods: Lumbar and cervical segments of the porcine cadaver spine were used for the IL-PELP.

Accuracy of Three Cone Beam Computed Tomography Systems in the Detection of Implant-Abutment Misfit.

Purpose: To assess the accuracy of three cone beam computed tomography (CBCT) systems in misfit detection at the implant-abutment joint.

Materials And Methods: A total of 32 implants were placed in dry human mandibles. Porcelain-fused-to-metal crowns, both with and without a 200-μm-thick gap at the implant-abutment joint, were placed and then scanned using three CBCT systems: Picasso Trio (PT), OP300 (OP), and Scanora 3D (SC).

Multigenerational prediction of genetic values using genome-enabled prediction.

The identification of elite individuals is a critical component of most breeding programs. However, the achievement of this goal is limited by the high cost of phenotyping and experimental research. A significant benefit of genomic selection (GS) to plant breeding is the identification of elite individuals without the need for phenotyping.

Experimental model for transforaminal endoscopic spine.

Purpose: To validate the porcine spine as a model for learning and practicing transforaminal percutaneous endoscopic lumbar procedures (TF-PELP).

Methods: TF-PELP was performed in three porcine cadaver lumbar spine levels. Anatomical features of the current cadaver were compared to human and porcine spines.

Neurosurgical Management of Pott's Puffy Tumor in an Obese Adolescent with Asthma: Case Report with a Brief Review of the Literature.

Pott's puffy tumor is a rare and severe complication of frontal sinusitis, characterized by the progressive swelling of the frontal soft tissues secondary to a subperiosteal abscess. Radiological imaging with ultrasound, computed tomography (CT), and magnetic resonance imaging (MRI) are important diagnostic tools in establishing diagnosis and treatment planning. Early surgery along with intravenous antibiotics are required in order to achieve a good recovery.

Diagnostic accuracy of 4 intraoral radiographic techniques for misfit detection at the implant abutment joint.

Statement Of Problem: A misfit or gap at the implant-abutment joint (IAJ) requires detection as it may compromise the health of the peri-implant tissue. However, which radiographic technique provides the most orthogonal relationship between the central beam and the implant/image receptor is unclear.

Purpose: The purpose of this in vitro study was to evaluate the diagnostic accuracy of 4 intraoral radiographic techniques on misfit detection at the IAJ.

Radical cystectomy with pelvic lymphadenectomy: pathologic, operative and morbidity outcomes in a Brazilian cohort.

Introduction And Objective: Radical cystectomy (RC) with pelvic lymph node dissection is the standard treatment for muscle invasive bladder cancer and the oncologic outcomes following it are directly related to disease pathology and surgical technique. Therefore, we sought to analyze these features in a cohort from a Brazilian tertiary oncologic center and try to identify those who could negatively impact on the disease control.

Patients And Methods: We identified 128 patients submitted to radical cystectomy, for bladder cancer treatment, from January 2009 to July 2012 in one oncology tertiary referral public center (Mario Penna Institute, Belo Horizonte, Brazil).
