Randomized Controlled Trial Comparative StudyIs clonidine an adequate alternative to epinephrine as a vasoconstrictor in patients with hypertension?
To evaluate the safety and efficacy of an admixture of lidocaine with clonidine with regard to the anesthetic abilities, hemodynamic parameters, and postoperative pain control and to compare the results with those obtained with a lidocaine-epinephrine solution. ⋯ Clonidine could be a useful and safe alternative to epinephrine for intraoral block anesthesia with lidocaine in patients with hypertension and American Society of Anesthesiologists class II.

ReviewPET-MRI fusion in head-and-neck oncology: current status and implications for hybrid PET/MRI.
To review the current status and clinical effect of PET-MRI image fusion in the staging of head-and-neck cancer and to show its implications for imaging with future hybrid PET/MRI scanners. ⋯ Combined PET/MRI scanners might overcome the above-named problems. Both sequential and fully integrated PET/MRI scanners are now available in selected departments, and future studies will show whether hybrid PET/MRI is of greater clinical value than PET/CT and retrospective image fusion techniques.

Comparative StudyCranioplasty with custom-made implants: analyzing the cases of 10 patients.
The aim of this study was to assess quantitatively whether a symmetric reconstruction of the calvaria could be achieved using 3-dimensional (3D) custom-made implants and to examine any complications caused by the cranioplasty. ⋯ The custom-made implants for cranioplasty showed a significant improvement in morphology. The implants may be very useful for repairing large and complex-shaped cranial defects. The technique may be useful for the bone reconstruction of other sites.

Verification of nerve integrity after surgical intervention using quantitative sensory testing.
The aim of this study was to apply a standardized Quantitative Sensory Testing (QST) approach in patients to investigate whether oral surgery can lead to sensory changes, even if the patients do not report any sensory disturbances. Furthermore, this study determines the degree and duration of possible neuronal hyperexcitability due to local inflammatory trauma after oral surgery. ⋯ The results show that oral surgery can lead to sensory deficits in the mental and lingual region, even if the patients do not notice any sensory disturbances. The applied QST battery is a useful tool to investigate trigeminal nerve function in the early postoperative period. In light of the increasing forensic implication, this tool can serve to objectify clinical findings.

Comparative StudyComparison of current perception threshold electrical testing to clinical sensory testing for lingual nerve injuries.
We performed a retrospective study of lingual nerve injury assessment comparing the techniques of current perception threshold testing versus clinical sensory testing. ⋯ The significant correlations observed in the present study indicate that current perception threshold can be a complementary or alternative tool in the assessment and evaluation of lingual nerve injuries.
