Mesothelial cyst of the round ligament of the uterus A case report of a rare condition
2021
Le cisti mesoteliali del legamento rotondo sono una rara causa di tumefazione inguinale nelle donne, la loro eziopatogenesi rimare poco chiara e i casi riportati in letteratura sono scarsi. Inoltre, quest’ultime sono raramente prese in considerazione nella diagnosi differenziale delle tumefazioni della regione inguinale nelle pazienti di sesso femminile, ragion per cui sono spesso identificate solo in corso di esplorazione chirurgica e correttamente diagnosticate solo dopo esame istopatologico. Una donna di 57 anni (BMI 37 kg / m2) si è presentato nel nostro dipartimento con una massa inguinale sinistra, con storia di 2 mesi, che causava disagio locale e peggioramento progressivo del dolore…
Morphology of the dorsal and lateral calcaneocuboid ligaments.
2008
Background: The dorsolateral calcaneocuboid ligaments have different configurations. In the literature they are only described as either the dorsal or lateral calcaneocuboid ligament. However, recent reconstructive surgical techniques may benefit from a better understanding of the anatomy. The aims of this study were to classify the morphology and attachments of the dorso-lateral calcaneocuboid ligaments and to determine their dimensions. Materials and Methods: The dorso-lateral aspects of the calcaneocuboid joint of 30 cadaver feet were dissected to expose the associated ligaments. Further, we evaluated possible bony landmarks of the calcaneus that could imply which shape or course the li…
Human adult periodontal ligament-derived cells integrate and differentiate after implantation into the adult mammalian brain.
2013
Previous studies suggest that neural crest (NC)-derived stem cells may reside in NC derivatives including the human periodontal ligament (hPDL). The isolation and manipulation of autologous NC-derived cells could be an accessible source of adult neural stem cells for their use in cell replacement and gene transfer to the diseased central nervous system. In this study, we examined the expression of NC markers and neural differentiation potential of hPDL-derived cells both in vitro and in vivo. In vitro we found that hPDL-derived cells expressed stem cell markers (Oct3/4, Nestin, Sox2, and Musashi-1) and a subset of NC cell markers (Slug, p75(NTR), Twist, and Sox9). hPDL-derived cells differe…
ACL Rehabilitation Enhanced by 3D Modeling Software
2010
The main purpose of this paper is to show possible positive effect of 3D modeling application in rehabilitation. Authors provide clinic example of patient with ACL reconstruction. The patient has undertaken the therapy consisting of regular rehabilitation sessions as well as those enhanced by 3D rehabilitation application. The improvement in ACL rehabilitation was significant and worth further exploration.
Clinical and radiological features of Forestier's disease presenting with dysphagia
2018
Background Diffuse idiopathic skeletal hyperostosis (DISH), also known as Forestier's disease, is a rheumatologic condition characterized by ossification of the spinal ligaments and tendons. Large anterior osteophytes are typically present in the lower cervical levels, while upper cervical ossification resulting in dysphagia is very rare. Methods Here, we presented a patient with Forestier's disease involving massive ossification of the anterior longitudinal ligament extending from C3 to C4 downward contributing to severe dysphagia. Results A 65-year-old male presented with cervical pain and dysphagia. The computed tomography of the cervical spine demonstrated massive anterior longitudinal …
A non-linear stochastic approach of ligaments and tendons fractional-order hereditariness
2020
Abstract In this study the non-linear hereditariness of knee tendons and ligaments is framed in the context of stochastic mechanics. Without losing the possibility of generalization, this work was focused on knee Anterior Cruciate Ligament (ACL) and the tendons used in its surgical reconstruction. The proposed constitutive equations of fibrous tissues involves three material parameters for the creep tests and three material parameters for relaxation tests. One-to-one relations among material parameters estimated in creep and relaxations were established and reported in the paper. Data scattering, observed with a novel experimental protocol used to characterize the mechanics of the tissue, w…
Localización exacta de la inserción femoral y medida de la distancia entre el punto de inserción femoral y patelar de la plastia de ligamento patelof…
2016
Introducción: La reconstrucción del ligamento patelofemoral medial (LPFM) es el procedimiento de elección en el tratamiento de los pacientes que sufren episodios de inestabilidad rotuliana lateral crónica. Sin embargo, se desconoce el punto exacto de fijación de la plastia del LPFM al fémur y los efectos en la clínica de una inserción femoral no anatómica. Objetivos: (1) Estudiar la biomecánica del injerto de LPFM reconstruido in vivo mediante imágenes 3D de Tomografía Computarizada (TC) a diferentes ángulos de flexión; (2) establecer la precisión de los métodos radiográficos de Schöttle y Stephen en la identificación del punto de fijación femoral de la plastia de LPFM tomando como referenc…
The role of platelet gel in osteoarticular injuries of young and old patients
2014
Background: The use of autologous platelet gel in orthopedics is effective in accelerating the healing process of osteochondral, muscle, tendon and ligament lesions. The aim of our study was to verify whether the variability in response to infiltration with platelet gel was dependent on the underlying disease treated, sex and age of the patients. During four years, 140 patients have been treated for musculoskeletal injuries by infiltration of gel platelet and lysate platelet obtained from autologous thrombin, with echo-ultrasound guided. The response to treatment was assessed at different time points T0, T1, T2 with respect to pain estimation (VAS), joint mobility (ROM scale) and echo-ultra…
Evaluation of changes in ion release and biological properties of NeoMTA‐Plus and Endocem‐MTA exposed to an acidic environment
2018
AIM To analyse in vitro changes in ion release and biological properties of Endocem-MTA (Maruchi, Wonju, Korea) and NeoMTA-Plus (Avalon Biomed Inc, Bradenton, FL, USA) exposed to acidic or neutral environment on human dental periodontal ligament stem cells (hPDLSCs). METHODOLOGY Cell viability and wound healing assays were performed using eluates of each material. Cell death and changes in phenotype induced by the set endodontic sealer eluates were evaluated through flow cytometry. To evaluate cell attachment to the different materials, hPDLSCs were directly seeded onto the material surfaces and analysed by scanning electron microscopy. The chemical composition of the materials was determin…
Validation of the German version of the Kujala score in patients with patellofemoral instability : a prospective multi-centre study
2017
Introduction: The Kujala score is the most frequently used questionnaire for patellofemoral disorders like pain, instability or osteoarthritis. Unfortunately, we are not aware of a validated German version of the Kujala score. The aim of our study was the translation and linguistic validation of the Kujala score in German-speaking patients with patella instability and the assessment of its measurement characteristics. Materials and methods: The German Kujala score was developed in several steps of translation. In addition to healthy controls, the Kujala German was assessed in consecutive patients undergoing reconstruction of the medial patellofemoral ligament for recurrent patellar dislocat…
