Item Effect of lidocaine patches on upper trapezius EMG activity and pain intensity in patients with myofascial trigger points: a randomized clinical study(Norstedts Förlag, 2015) Firmani, Monica; Miralles, Rodolfo; Casassus, RodrigoOBJECTIVE: To compare the effects of 5% lidocaine patches and placebo patches on pain intensity and electromyographic (EMG) activity of an active myofascial trigger point (MTrP) of the upper trapezius muscle. MATERIALS AND METHODS: Thirty-six patients with a MTrP in the upper trapezius muscle were randomly divided into two groups: 20 patients received lidocaine patches (lidocaine group) and 16 patients received placebo patches (placebo group). They used the patches for 12 h each day, for 2 weeks. The patch was applied to the skin over the upper trapezius MTrP. Spontaneous pain, pressure pain thresholds, pain provoked by a 4-kg pressure applied to the MTrP and trapezius EMG activity were measured before and after treatment. RESULTS: Baseline spontaneous pain values were similar in both groups and significantly lower in the lidocaine group than the placebo group after treatment. The baseline pressure pain threshold was significantly lower in the lidocaine group, but after treatment it was significantly higher in this group. Baseline and final values of the pain provoked by a 4-kg pressure showed no significant difference between the groups. Baseline EMG activity at rest and during swallowing of saliva was significantly higher in the lidocaine group, but no significant difference was observed after treatment. Baseline EMG activity during maximum voluntary clenching was similar in both groups, but significantly higher in the lidocaine group after treatment. CONCLUSIONS: These clinical and EMG results support the use of 5% lidocaine patches for treating patients with MTrP of the upper trapezius muscle.Item Fenómenos fisiopatológicos sistémicos asociados al bruxismo de sueño(2014) Iturriaga, V.; Bornhardt, T.; Casassus, Rodrigo; Alveal, C.; Medina, H.; Reuque, C.El bruxismo de sueño (BS) se define como un trastorno del movimiento estereotipado que se presenta durante el sueño, caracterizado por rechinamiento y/o apretamiento dentario. Se encuentra dentro de la clasificación internacional de desórdenes de sueño como un trastorno del movimiento asociado a una exagerada actividad muscular masticatoria rítmica. Se reporta una incidencia del 15% al 22% en la población general. Antiguamente se creía que la etiología del BS estaba relacionada con alteraciones oclusales; sin embargo actualmente se piensa que la causa principal está más bien relacionada con alteraciones de sueño, enfermedades del sistema nervioso central, drogas, dolor crónico, alteraciones emocionales, entre otros factores que participarían en su origen. Se ha identificado la presencia de diversos fenómenos fisiopatológicos sistémicos que acontecen durante un episodio de BS, entre los cuales encontramos los microdespertares corticales, alteraciones en el ritmo cardíaco, el tono simpático, la presión arterial, entre otros, sobre los cuales trata esta revisión.Item Pediatric patients' reasons for visiting dentists in all WHO regions(2021) Bekes, Katrin; John, Mike T.; Rener-Sitar, Ksenija; Al-Harthy, Mohammad H.; Michelotti, Ambra; Reissmann, Daniel R.; Nikolovska, Julijana; Sanivarapu, Sahityaveera; Lawal, Folake B.; List, Thomas; Peršić Kiršić, Sanja; Strajnić, Ljiljana; Casassus, Rodrigo; Baba, Kazuyoshi; Schimmel, Martin; Amuasi, Ama; Jayasinghe, Ruwan D.; Strujić-Porović, Sanela; Peck, Christopher C.; Xie, Han; Haugaard Bendixen, Karina; Simancas-Pallares, Miguel Angel; Perez-Franco, Eka; Naghibi Sistan, Mohammad Mehdi; Valerio, Patricia; Letunova, Natalia; Nurelhuda, Nazik; Bartlett, David W.; Oluwafemi, Ikeoluwa A.; Dghoughi, Saloua; Ferreira, Joao N A R; Chantaracherd, Pathamas; Sekulić, StellaBackground: Oral Function, Orofacial Pain, Orofacial Appearance, and Psychosocial Impact are the four oral health-related quality of life (OHRQoL) dimensions (4D) or areas in which oral disorders impact pediatric patients. Using their dentists' assessment, the study aimed to evaluate whether pediatric dental patients' oral health concerns fit into the 4D of the Oral Health-Related Quality of Life (OHRQoL) construct. Methods: Dentists who treat children from 32 countries and all WHO regions were selected from a web-based survey of 1580 international dentists. Dentists were asked if their pediatric patients with current or future oral health concerns fit into the 4D of the Oral Health-Related Quality of Life (OHRQoL) construct. Proportions of all pediatric patients' oral health problems and prevention needs were computed. Findings: Data from 101 dentists treating children only and 523 dentists treating children and adults were included. For 90% of pediatric patients, their current oral health problems fit well in the four OHRQoL dimensions. For 91% of oral health problems they intended to prevent in the future were related to these dimensions as well. Both numbers increased to at least 96% when experts analyzed dentists´ explanations of why some oral health problems would not fit these four categories. Conclusions: The study revealed the four fundamental components of dental patients, i.e., the four OHRQoL dimensions (Oral Function, Orofacial Pain, Orofacial Appearance, and Psychosocial Impact) are also applicable for pediatric patients, regardless of whether they have current or future oral health concerns, and should be considered when measuring OHRQoL in the pediatric dental patient population.
