Parotiditis recurrent juvenil. Caldria pensar-hi més? / Parotiditis recurrente juvenil. ¿Deberíamos pensar más en ella? / Juvenile recurrent parotitis. Should we think more about it?

Introducció. La parotiditis recurrent juvenil (PRJ) és una entitat poc freqüent, però representa la segona causa de patologia de les glàndules salivals de la infància. Es caracteritza per episodis repetits de tumefacció i dolor local, de vegades acompanyats de febre, sense causa que ho justifiqui. La seva etiologia és desconeguda, probablement multifactorial, però diferents estudis relacionen la malaltia amb processos autoimmunitaris. El seu tractament habitualment és simptomàtic i conservador, però pot arribar a requerir tractament quirúrgic en alguns casos. Cas clínic. Es presenta el cas d’un nen de cinc anys amb episodis repetits de dolor a l’angle mandibular dret, habitualment autolimitats en menys de 24 hores, de dos anys d’evolució. Es practica una ecografia parotídia que mostra la presència d’imatges hipoecogèniques bilaterals característiques de la PRJ. Comentaris. No hi ha cap algoritme diagnòstic i d’abordatge de la tumefacció parotídia de repetició, però sembla apropiat estudiar la presència de litiasis parotídies, infeccions víriques, sobretot pel virus de la immunodeficiència humana (VIH), processos autoimmunitaris i immunodeficiències.

Introduction. Juvenile recurrent parotitis (JRP) is a rare condition but is the second most common childhood disease of the salivary glands. JRP usually presents with recurrent swelling and pain of the parotid glands, sometimes with fever, with no apparent cause. There is no conclusive aetiology; it is probably multifactorial, but multiple studies suggest an autoimmune phenomenon. Management has focused on the symptomatic and conservativetreatment of acute episodes but sometimes surgical procedures may be needed. Case report. A five-year-old boy presented with a two-year history of recurrent episodes of pain and swelling in the right mandibular angle that usually resolved within 24 hours. Ultrasound showed multiple hypoechoic lesions in both parotid glands, suggestive ofjuvenile recurrent parotitis. Comments. A management algorithm of recurrent parotid swelling should include the study of parotid lithiasis, viral infections, especially human immunodeficiency virus (HIV), autoimmune diseasesand immunodeficiencies.

Histological differences in the adherence of connective tissue to laser-treated abutments and standard abutments for dental implants. An experimental pilot study in humans

Background: The goal of the current study is to assess the difference in connective tissue adherence to laser microtextured versus machined titanium abutments. Material and Methods: Six patients were selected and each of them received 2 implants, one combined with a laser treated abutment and one with a machined abutment. After three months, the abutments were retrieved together with their surrounding gingival tissue for histological analysis. Qualitative and quantitative evaluation of microscopical images was performed to assess the presence or absence of adherence between the soft tissues and the abutment, and the percentage of soft tissue adhered to the two different surfaces. Results: Intimate adherence between connective tissue and the laser treated abutments, while on machined abutments no adherence was detected. A significant difference was found in the percentage of surface in contact with soft tissue between both implant abutments p=0.03. Conclusions: Within the limitation of the current study, it can be concluded that connective tissues show enhanced adherence to microtextured abutments compared to machined abutments (AU)

Influence of surface modified dental implant abutments on connective tissue attachment: A systematic review.

OBJECTIVE: Determine whether surface modified prosthetic abutments for dental implants influence connective tissue attachment to the implant-abutment system. DESIGN: A systematic review was conducted using the MEDLINE-PubMed database, with two independent reviewers filtering the titles and abstracts. Two reviewers assessed all potentially relevant articles. An assessment was carried out on the level of evidence of the research according to the guidelines of the Oxford Centre for Evidence-Based Medicine (OCEBM). RESULTS: After an initial search, 109 potentially relevant articles were found. After reading the titles and abstracts, 99 articles were excluded because the surface treatment was limited to the implant and not to the abutment, or because different materials were analysed instead of surface treatments; 28 were also duplicate articles. An additional 6 research studies were included that were of interest and were found by reading the references of the included articles. The studies included are: 7 in vitro studies, 5 experimental studies in animals, 2 clinical trials in humans and 2 clinical cases. CONCLUSION: Surface modification for prosthetic abutments on dental implants can achieve connective tissue attachment to the abutment; however, more studies should be conducted in humans to obtain more and better evidence of these results.
