Diffuse-Type Tenosynovial Giant Cell Tumor An Update of Current Management Strategies.

Diffuse-type giant cell tumor (Dt-GCT), formerly known as pigmented villonodular synovitis, is the more aggressive entity belonging to the spectrum of benign proliferative lesions of synovial origin that may affect the joints, bursae, and tendon sheaths. Diffuse-type giant cell tumor's importance stems from its local aggressiveness and sequelae if left untreated. This review briefly describes Dt-GCT's clinical features, its imaging and pathology findings, and provides an extensive discussion of its available treatments.

V-Y Quadricepsplasty for Knee Stiffness Post Total Knee Arthroplasty: A Case Report and Literature Review.

Introduction: Knee stiffness post-total knee arthroplasty (TKA) represents a common and challenging complication. Standard treatment protocols primarily include physical therapy, manipulation under anesthesia (MUA), fibrotic tissue release, lysis of adhesions (LOA), and in refractory cases, revision arthroplasty. However, these interventions often show minimal improvement in refractory cases.

Isolated lateral radial head dislocation in a child: A case report and literature review.

Introduction: Radial head dislocations in children can result from congenital anomalies, traumatic events, or as part of more complex injuries like Monteggia fractures. These dislocations are rare and may be overlooked unless considered in differential diagnoses.

Infantile Fibrosarcoma of the Bone: A Case Report and Literature Review.

Introduction: In adults, fibrosarcoma (FS) of the bone is a rare occurrence. Infantile FS, particularly in the distal radius, is an exceedingly uncommon tumor and, to the best of our knowledge, has not yet been documented in the literature. In the subsequent report, we present a case involving a 2-year-old male diagnosed with primary FS of the distal radius.

Arthroscopic Meniscus Trephination: A Novel Technique for the Treatment of Symptomatic Meniscal Degeneration: Surgical Technique and Literature Review.

Introduction: Meniscal pathology constitutes a major reason for a vast number of patients suffering from knee pain. It is, in general, attributed either to meniscal tearing or degeneration. Debridement and partial meniscectomy, or repair, when possible, is the mainstay surgical approach for refractory knee pain from meniscal degeneration or tears.

Regional versus general anesthesia in knee arthroplasty in patients with different classes of BMI: A matched analysis of the NSQIP database.

Background: Knee arthroplasty for knee arthritis is a commonly performed surgery yielding excellent functional results and good pain relief. It is associated with post-surgical complications according to the type of anesthesia and BMI class.

Methods: The National Surgical Quality Improvement Project database for the years 2005-2012 for patients >18 years of age who underwent knee arthroplasty, condyle and plateau, medial and/or lateral compartment.

A Meta-analysis Comparing External Fixation against Open Reduction and Internal Fixation for the Management of Tibial Plateau Fractures.

Aim: This article aims to compare the outcomes between open reduction and internal fixation (ORIF) and external fixation (ExFix) in tibial plateau fractures.

Background: Open reduction and internal fixation and external fixation are common methods for managing tibial plateau fractures without a consensus of choice.

Materials And Methods: PubMed, Cochrane Library, Ovid, CINAHL®, Scopus, and Embase were searched.

Primary dural lymphoma: Case report.

Primary Dural lymphoma (PDL) is a rare pathology that occurs in immunocompetent patients. In such cases, these lesions may mimic more common intracranial tumors. We present the case of a patient who presented an intra cranial hypertension syndrome; the brain MRI showed a tissular mass that we took for a meningioma; upon surgical intervention, an occult mass was discovered.

Kernohan Woltman notch phenomenon caused by subdural chronic hematoma: Systematic review and an illustrative case.

Kernohan Woltman Notch Phenomenon (KWNP) is caused by a supratentorial lesion pressing the contralateral cerebral peduncle against the free edge of the tentorium of the cerebellum. It is manifested by neurological signs of ipsilateral localization; cerebral MRI is the most sensitive examination for KWNP. Our patient is a 50-year-old woman, operated in 2011 for aortic and mitral valve replacement by mechanical prosthesis, under oral anticoagulant, consults for headaches evolving for 20 days without any notion of head trauma with installation of a progressively worsening left hemibody deficit.

Sacrococcygeal Local Anesthesia for Complicated Versus Uncomplicated Pilonidal Sinus Surgery: A Single Center Study.

Background: Several anesthetic techniques have been used for pilonidal sinus surgery such as general, spinal, and local anesthesia infiltration. However, the most effective technique remains controversial. The aim of this study was to assess the effectiveness of sacrococcygeal local anesthesia for complicated pilonidal cysts in terms of postoperative analgesic consumption.

Pediatric brain hydatid cyst about two cases: Case report.

Cerebral hydatid cyst is rare (2%), and mainly affects children. We report 2 cases aged 5 years. The clinical symptomatology was dominated by intracranial hypertension syndrome and motor deficit in both cases.

The role of PAK4 in the immune system and its potential implication in cancer immunotherapy.

The p21 activated kinases (PAKs) are known to play a role in the regulation of cell morphology and functions. Among the various members of PAKs family, only the PAK4 protein has been shown to be overexpressed in cancer cells and its upregulation was associated with tumor development. Indeed, several studies have shown that PAK4 overexpression is implicated in carcinogenesis by different mechanisms including promotion of cell proliferation, invasion and migration, protection of cells from apoptosis, stimulation of the tumor-specific anchorage-independent cell growth and regulation of the cytoskeletal organisation and adhesion.

Sub-10 nm spatial resolution for electrical properties measurements using bimodal excitation in electric force microscopy.

We demonstrate that under ambient and humidity-controlled conditions, operation of bimodal excitation single-scan electric force microscopy with no electrical feedback loop increases the spatial resolution of surface electrical property measurements down to the 5 nm limit. This technical improvement is featured on epitaxial graphene layers on SiC, which is used as a model sample. The experimental conditions developed to achieve such resolution are discussed and linked to the stable imaging achieved using the proposed method.
