- Introduction: This paper describes the development of "Swedish Guidelines for OSA treatment" and the underlying managed care process. The Apnea Hypopnea Index (AHI) is traditionally used as a single parameter for obstructive sleep apnea (OSA) severity classification, although poorly associated with symptomatology and outcome. We instead implement a novel matrix for shared treatment decisions based on available evidence. Methods: A national expert group including medical and dental specialists, nurses, and patient representatives developed the knowledge-driven management model. A Delphi round was performed amongst experts from all Swedish regions (N = 24). Evidence reflecting treatment effects was extracted from systematic reviews, meta-analyses, and randomized clinical trials. Results: The treatment decision in the process includes a matrix with five categories from a "very weak"" to "very strong" indication to treat, and it includes factors with potential influence on outcome, including (A) OSA-related symptoms, (B) cardiometabolic comorbidities, (C) frequency of respiratory events, and (D) age. OSA-related symptoms indicate a strong incitement to treat, whereas the absence of symptoms, age above 65 years, and no or well-controlled comorbidities indicate a weak treatment indication, irrespective of AHI. Conclusions: The novel treatment matrix is based on the effects of treatments rather than the actual frequency of respiratory events during sleep. A nationwide implementation of this matrix is ongoing, and the outcome is monitored in a prospective evaluation by means of the Swedish Sleep Apnea Registry (SESAR).

- P>Obstructive sleep apnoea (OSA) is a highly prevalent sleep disorder; it affects 4% of males and 2% of females. Hypertension has been shown to occur in 28-57% of OSA patients. There is a steady increase in evidence linking OSA to long-term cardiovascular morbidity including hypertension. The purpose of this study was to investigate whether mandibular advancement oral appliance (OA) treatment of OSA affects the patient's blood pressure (BP) in a 3-month and a 3-year perspective. Twenty-nine consecutive patients, with verified OSA defined as apnoea index (AI) > 5 per hour and/or apnoea/hypopnoea index (AHI) >= 10 per hour, received an OA as treatment. BP was measured on three occasions; before treatment, after 3 months of treatment, and after 3 years of treatment. BP was measured with an electronic blood pressure monitor. The treatment effect of OA was measured after 3 months by repeated somnographic registration while the patient was wearing the OA. A treatment response was defined as AHI < 10; this was achieved in 25 of 29 patients (86%) at the 3-month evaluation. Significant reductions in blood pressure were attained between baseline and the 3-month evaluation (P < 0 center dot 001) and these changes remained at the 3-year follow-up in both systolic BP of -15 center dot 4 +/- 18 center dot 7 mm Hg and diastolic BP of -10 center dot 3 +/- 10 center dot 0 mm Hg. OA therapy reduced blood pressure in both a 3-month and a 3-year perspective in patients with OSA.

- Introduction: The clinical benefit of bibloc over monobloc appliances has not been established in randomized trials treating obstructive sleep apnoea (OSA). We hypothesized that the two types of appliances are equally effective in treating moderate to severe OSA. Materials and methods: We performed a blinded, multicenter, randomized, controlled, prospective, parallel-group trial including patients aged 18 years or older who had moderate-to-severe OSA. Patients were randomly assigned to receive either a bibloc or a monobloc appliance with the intention to protrude the mandible 75% of the individual maximal protrusion capacity. At baseline a one-night respiratory polygraphy was done without any respiratory support. The polygraphy was iterated with the appliance in place at a 6-week follow-up. The primary outcome was the absolute change in the apnoea-hypopnea-index (AHI) from baseline to the 6-week follow-up, analysed in the per-protocol population. All patients who received an appliance were included in the safety analysis. This trial is registered with ClinicalTrials.gov, number NCT02148510, and approved by Uppsala Regional Ethical Review Board, Sweden (#2014/021). Results: We recruited patients from three dental specialist clinics in Sweden; enrolment of 302 patients was done between March 2014 and April 2016; 146 randomized to bibloc and 156 to monobloc appliance. Twenty-three patients in the bibloc group and 17 in the monobloc group were withdrawn due to reasons like appliance could not be fitted, lack of compliance, adverse events or non-valid follow-up polygraphy i.e. a per-protocol group of 123 bibloc and 139 monobloc treated patients. The mean change of AHI from baseline to 6 weeks of treatment was -13.8 (95% CI -16.1 to -11.5; p < 0.001) in the bibloc group and -12.5 (95% CI -14.8 to -10.3; p < 0.001) in the monobloc group. The mean difference was not significant between the groups (-1.3 (95% CI -4.5 to 1.9). The most common adverse event in the orofacial region was upper airway infection followed by complains from various parts of the mouth, jaws and teeth. Conclusions: Bibloc and monobloc appliance treatment was equal in their effects in treating OSA as measured by at home polygraphic respiratory measures and the appliances were associated with a similar degree of adverse events.

- The aim of this study was to determine the analgesic efficacy of a single dose intra-articular injection (i.a.) of morphine in 53 patients with unilateral arthralgia/osteoarthritis of the temporomandibular joint (TMJ). This randomized, double-blind, parallel group, multicenter study included a screening visit, a treatment visit, and a follow-up visit 1 week after treatment. Recordings of visual analog scales (VAS) pain intensity scores at maximum mouth opening (main efficacy variable) and at jaw rest were made directly before a 1-ml i.a. injection into one TMJ of either 1.0 mg morphine-HCl, 0.1 mg morphine-HCl, or saline (placebo). The pain intensity was also recorded at the follow-up and in a diary 3 days before and 5 days after the injection. The VAS pain score at maximum mouth opening was considerably reduced 1-10 h after injection but without significant differences between groups. At the follow-up, the median VAS pain score at maximal mouth opening was significantly lower in the 0.1-mg morphine group than in the 1.0-mg morphine group (P < 0.043) or the saline group (P < 0.021). A significant increase in pain pressure threshold over the affected joint was seen in the 0.1-mg morphine group compared with the saline group at the follow-up but not 1 and 2 h post-injection. The incidence of adverse events was small and did not differ between the treatment groups. In conclusion, one i.a. injection of 0.1 mg morphine significantly increased the pain pressure threshold and mouth opening ability, but evidence for the analgesic property of the locally applied opioid was inconclusive. No dose-effect relation and no significant short-term analgesic property were seen. Although statistically significant, the magnitude of the reduced VAS pain intensity score was not clinically relevant at the 1-week follow-up. © 2001 International Association for the Study of Pain.
