Predictability of short implants ( < 10 mm) as a treatment option for the rehabilitation of atrophic maxillae: a systematic review
2016
Background Short implants (< 10 mm) are one of the treatment options available in cases of limited vertical bone. A purpose of this paper is to evaluate the predictability of short implants as an alternative to technically molthough such implants are now widely used, there is controversy regarding their clinical reliability. There complex treatments in patients with atrophic maxillae, based on a systematic review of the literature and the analysis of the implant survival rates, changes in peri-implant bone level, and associated complications. It is postulated that short implants offer clinical results similar to those of longer implants. Material and Methods A Medline-PubMed search was made…
Minimally invasive prosthetic procedures in the rehabilitation of a bulimic patient affected by dental erosion
2015
The population affected by dental erosion due to bulimia is generally very young. This population group has a high aesthetic requirement; the dentition in these patients is severely damaged, especially in the anterior maxillary quadrant. In terms of treatment, it is still controversial whether an adhesive rehabilitation is preferable to a longer-lasting but more aggressive conventional treatment, such as full-crown coverage of the majority of teeth. This case report describes the prosthetic rehabilitation of a young female patient previously affected by bulimia nervosa and presenting erosion of the maxillary teeth. The prosthetic rehabilitation was performed through indirect adhesive restor…
Alteraciones salivares en pacientes con diabetes tipo 2
2006
La diabetes mellitus tipo 2 es el desorden metabólico más frecuente, siendo además causante de una importante morbi-mortalidad. En estos pacientes se han descrito alteraciones estructurales de la parotida (sialosis) que podrían comportar modificaciones en la composición salivar, así como un incremento de patología dental y periodontal. Objetivos: establecer las alteraciones bioquímicas de la saliva y su posible correlación con los hallazgos morfológicos. Diseño del estudio: se realizo un estudio clínico de 33 pacientes, 17 de ellos con diabetes tipo 2. Se recogieron muestras de saliva para análisis bioquímico y suero para control metabólico. Resultados: en la saliva de los pacientes diabéti…
Pfeiffer syndrome: clinical and genetic findings in five Brazilian families
2014
Pfeiffer syndrome (PS) is mainly characterized by craniosysnostosis, midface hypoplasia, great toes with partial syndactyly of the digits and broad and medially deviated thumbs. It is caused by allelic mutations in the fibroblast growth factor receptor 1 and 2 (FGFR1 and 2) genes. This study describes the clinical and genetic features of five Brazilian families affected by PS. All patients exhibited the classical phenotypes related to PS. The genetic analysis was able to detect the mutations Cys278Phe, Cys342Arg, and Val359Leu in three of these families. Two mutations were de novo, with one familial. We identified pathogenic mutations in four PS cases in five Brazilian families by PCR seque…
Detection of bifid mandibular condyle using computed tomography
2011
Objective: To determine the frequency and characteristics of bifid mandibular condyle (BMC) using computed tomography (CT) evaluation. Study Design: A retrospective study was carried out using the CT records of 550 patients referred to the Medical School of Erciyes University (Kayseri, Turkey) between 2007 and 2010. T-tests were used to compare frequency of BMC between the left and right sides and between female and male patients. Statistical analysis was performed using SPSS software and a chi-squared test. Results: Of the 550 Patients, 10 patients (1.82%) were found to have BMCs. Five patients were female (50%) and five were male (50%). Of these 10 patients, 7 (70%) had unilateral and 3 (…
Arthroscopic approach for treating a pigmented villonodular sinovitis of TMJ. A case report
2017
The present report describes the case of a 29-year-old man referred to our service for TMJ pain and progressive reduction of the mouth opening. Differential diagnostics included rheumatologic diseases, monoarthritis and intraarticular lumps. In this line, a face CT scan and a MRI of TMJ were carried out in order to ensure a proper diagnosis. These tests showed a solid lesion into the joint cavity. In view of that, we decided to perform a diagnostic and therapeutic arthroscopy of TMJ. Histopathological studies confirmed the diagnosis of pigmented villonodular synovitis. The main aim of this report is to describe this rare syndrome with the goal of proposing suitable treatments. Moreover, we …
Osteosarcoma of maxilla: a case report
2010
Osteosarcoma is a common primary malignant bone tumor producing osteoid or bone. It occurs very infrequently in the jaws and comprises of 4% of the tumour number as compared to the osteosarcoma of the long bones. Os- teosarcoma of the maxilla is even rarer presenting with common clinical features of pain and swelling. This pre- sented case is a rare case of osteosarcoma of maxilla in a 21-year-old female patient. Diagnosis and pre-operative assessment was performed using a combination of intraoral periapical radiograph, occlusal radiograph, paranasal view and computed tomography (CT). CT revealed destruction of the walls of maxillary sinus and sunray type of ossification in the soft tissues…
Estado actual de los tumores óseos
2015
En la presente actualización sobre el estado actual de los tumores óseos malignos, realizamos una revisión básica sobre todo en los avances de la biología molecular del osteosarcoma, sarcoma de Ewing y del condrosarcoma. Se presenta además un resumen sobre los avances y las posibilidades terapéuticas en el tratamiento quirúrgico de los tumores óseos malignos. In this article we review basic aspects of biology and surgical treatment of malignant bone tumors, mainly on advances the molecular biology of osteosarcoma, Ewing’s sarcoma and chondrosarcoma. Furthermore we present a summary of therapeutic progress and possibilities in the surgical treatment of malignant bone tumors.
Bases científicas para el tratamiento del desgarro muscular : movilización versus inmovilización
1996
Se exponen las bases científicas del tratamiento del desgarro muscular, haciendo una valoración de la reparación biológica de las lesiones en músculo estriado. Se estudia el «callo» muscular bajo las perspectivas de «lo conjuntivo» y «lo mioblástico». Se sacan consecuencias de orden terapéutico. The scientific basis for treatment of muscular injury arc considered trying to enlight the regeneration and biological repair of skeletal muscle. Muscular «callus» is studied under the perspectives of the connective and the mioblastic tissues. Some important derived consequence should be taken with account when treating this type of lesions.
Manifestaciones esqueléticas en la homocistinuria: a propósito de un caso
1994
Se presenta el caso de una niña de 13 años con homocistinuria en la que se describen las alteraciones esqueléticas, haciendo especial énfasis en las encontradas en el raquis, donde además de osteoporosis, ensanchamientos discales no uniformes y las alteraciones morfológicas de los somas vertebrales, existe una disminución de la distancia interpedicular en el raquis lumbar bajo. Se señalan los síntomas y signos radiológicos que son importantes para el diagnóstico diferencial con la enfermedad de Marfan. The skeletal alterations of a 13-year-old girl with homocystinuria are described emphasizing those found at the spine. Osteoporosis, non-uniform widening of the intervertebral discs, morpholo…
