Randomized Controlled Trial Comparative StudyComparing the effects of desflurane and isoflurane on middle ear pressure.
The aim of this study was to determine middle ear pressure changes during the operation performed under anaesthesia induced by isoflurane or desflurane. This was a prospective, case-control study. A total of 38 children with no middle ear pathology scheduled for inguinal hernia surgery were included in the study. ⋯ Increase in the mean middle ear pressure values at the 5(th) and 10(th) minute of the operation was significant different between both groups (2.84 and 5.80 daPa for isoflurane; 59.06 and 72.81 daPa for desflurane; p ≤ 0.05). Desflurane is more increased than isoflurane on intra-tympanic pressure and isoflurane may be used more safely than desflurane in middle ear operations. The low effect of isoflurane on intra-tympanic pressure can be explained by the high blood/gas partition coefficient compared to desflurane.

Randomized Controlled Trial Comparative Study Clinical TrialTopical versus systemic diclofenac in the treatment of temporo-mandibular joint dysfunction symptoms.
The most frequent symptom of craniomandibular dysfunction is pain in the preauricular area or in the temporo-mandibular joint, usually localized at the level of the masticatory musculature. Patients sometimes also complain of reflect otalgia, headaches and facial pain. Osteoarthrosis is a frequent degenerative debilitating chronic disorder that can affect the temporomandibular joint. ⋯ The efficacy of diclofenac topically applied on the temporomandibular joint region observed in group B is explained by the association of diclofenac with dimethyl-sulfoxide, which enables a rapid effective penetration into the joint tissues. It is noteworthy that dimethyl-sulfoxide favours transuctaneous absorption when used in a multi-dose regime as in our study with 4 doses a day. Thus, single, "as required", applications should be avoided because this practice results in scarce absorption of diclofenac.

Randomized Controlled Trial Clinical Trial[Eutectic mixture of local anesthetics (EMLA): evaluation of the analgesic effectiveness during ND: YAG laser turbinoplasty].
The analgesic effect of EMLA anesthetic cream is evaluated during contact turbinoplasty with a Neodymium: yttrium-aluminum-garnet (Nd: Yag) laser. A total of 48 patients were selected and randomized in two groups. EMLA was applied on the nasal mucosa, respectively, for 15 and 30 minutes after using vasoconstrictor cottonoids. ⋯ The pain induced by the surgical procedure was evaluated with a visual analogic scale. The score obtained was significantly lower in the 1st group than in the 2nd group and this difference was statistically significant (p < 0.01). The EMLA anesthetic cream applied on the mucosa for 15 minutes allows to obtain a good analgesia during the functional contact turbinate surgery with a Nd: Yag laser and thus can be considered a valid alternative to anesthesia by local infiltration.
