ABSTRACT
In patients with limited mouth opening, traditional laryngoscopy and videolaryngoscopes are not useful when performing nasotracheal intubation. Eighty patients with limited mouth opening who required nasotracheal intubation were randomly assigned to either fibreoptic intubation (n = 40) or the Trachway(®) (n = 40). Using the modified nasal intubation difficulty scale, 22 (55%) patients who received fibreoptic intubation were categorised as no difficulty compared with 40 (100%) patients in the Trachway group (p < 0.001). Mean (SD) total intubation time was 71.8 (23.3) s in patients who received fibreoptic intubation compared with 35.4 (9.8) s in the Trachway group (p < 0.001). We conclude that the Trachway technique for nasotracheal intubation is quicker and easier compared with fibreoptic intubation in patients with limited mouth opening.

Fibreoptic intubation is a valuable modality for airway management. This study aimed to compare the effectiveness of dexmedetomidine vs target controlled propofol infusion in providing sedation during fibreoptic intubation. Forty patients with anticipated difficult airways and due to undergo tracheal intubation for elective surgery were enrolled and randomly allocated into the dexmedetomidine group (1.0 microg.kg(-1) over 10 min) (n = 20) or the propofol target controlled infusion group (n = 20). Intubating conditions and patient tolerance as graded by a scoring system were evaluated as primary outcomes. Intubation was successful in all patients. Satisfactory intubating conditions were found in both groups (19/20 in each group). The median (IOR [range]) comfort score was 2 (1-2 [1-4]) in the dexmedetomidine group and 3 (2-4 [2-5]) in the propofol group (p = 0.027), favouring the former. The dexmedetomidine group experienced fewer airway events and less heart rate response to intubation than the propofol group (p < 0.003 and p = 0.007, respectively). Both dexmedetomidine and propofol target-controlled infusion are effective for fibreoptic intubation. Dexmedetomidine allows better tolerance, more stable haemodynamic status and preserves a patent airway.

OBJECTS: With the advent of genetic technologies, many genetic/metabolic disorders can be detected asymptomatically but might be untreatable, and the benefits and risks of screening for them are not fully known. The purpose of this study is to explore current practice with regard to the parental consent process in newborn screening (NBS). DESIGN: Staff in 23 obstetric clinics/hospitals that conduct NBS in one city of southern Taiwan were interviewed. Using content analysis, 15 interview transcripts, eight completed questionnaires, and other relevant documents from the 23 clinics/hospitals were analysed to reveal the framework of the parental consent process in NBS in southern Taiwan. MAIN MEASURES: Three categories-informed consent, informed dissent, and no informed/consent-were developed to analyse the parental consent process in NBS. RESULTS: The parental consent procedures in NBS and the quality of the information provided before obtaining consent vary widely. Because the traditional NBS was incorporated into routine paediatric practices in most clinics/hospitals, the most frequently encountered consent model is "informed dissent" (60.9%) and "no informed/consent" (30.4%); while an "informed consent" model (45.5%) is the frequent model for screening rare metabolic/genetic disorders. CONCLUSIONS: Specific guidelines to regulate the parental consent process for NBS are essential. Further studies should investigate parental responses to NBS, taking these as the basis on which to establish an informed consent model in Taiwan.

Abstract Behçet's disease (BD) is a chronic relapsing systemic vasculitis of unknown etiology. BD is very rarely associated with neoplastic diseases. We report the case of a 39-year-old woman who had been treated for BD for 3 years. She presented with relapsing oral and genital lesions and persistent high-grade fever which had lasted for 1 month. The possible cause of the exacerbation of BD and fever in this patient was a mature ovarian teratoma. To our knowledge this is the first report of a patient with BD associated with a ovarian teratoma.
