Evaluation of a new 'anti-snoring device'.

A new 'antisnoring device' based on the principle to induce a conditioned response was evaluated in 8 patients with habitual snoring. When patients snore the device starts to vibrate, making the snorers turn to the side position. Out of the 8 patients, 4 definite responders were identified. In these individuals the cumulative overnight sound produced above 40 dBA was clearly reduced. Moreover, these patients reported decreased daytime hypersomnolence but no change in sleep quality after using the antisnoring device for 4 weeks. Sleep staging did not reveal any significant changes in sleep architecture. However, two patients in the responder group were found to have increased rapid eye movement sleep time and time spent in stage 3 and 4, respectively. No changes in oxygen saturation were found in the responder or the nonresponder groups. The results indicate that the anti-snoring device may be useful to decrease snoring and to improve sleep in a subgroup of habitual snorers. The data do, however, not provide further information on the characteristics of this subgroup.

Beta 2-microglobulin and its binding activity in serum from patients with SLE.

Repeated determinations of beta 2-microglobulin (beta 2m) and beta 2-microglobulin binding activity (beta 2m ba) in serum were performed during a follow-up of 23 patients with SLE. beta 2m was determined by a radioimmunoassay. Individual mean values were raised in 65% of the patients. The mean value for all patients, 2.9 mg/l, was significantly higher than that of the controls. The beta 2m concentrations parallelled the clinical disease activity in several cases with different disease manifestations. The beta 2m ba was determined by precipitation of 125I-labelled beta 2m with polyethylene glycol. Increased beta 2m ba was found in 26% of the SLE patients with the 90th percentile in 40 healthy subjects being taken as the upper normal limit. There were, however, no significant differences between the mean values for beta 2m ba in the patients and the controls. Patients with systemic lupus erythematosus (SLE), suffering exacerbation of their disease, had a higher mean beta 2m ba than those with less active disease. Variations of the serum beta 2m ba occurred especially in patients with active disease but did not seem to reflect the clinical course. The beta 2m ba was recovered in the IgG peak when SLE serum was subjected to gel chromatography on Sephadex G-200.

Eosinophilic fasciitis. Review and report of six cases.

Six patients with eosinophilic fasciitis are presented. This syndrome is characterized by indurative swellings of arms and legs, with rapidly progressing difficulties in extending elbows, wrists, and fingers, and often limited motion of shoulders and ankle joints. Pain when contracting muscles, and weakness of proximal muscles and hand grip are common features. The frequent occurrence of localized skin lesions has presented differential diagnostic difficulties to systemic sclerosis and to polymyositis. Visceral involvement and Raynaud's phenomena, however, are absent or mild. Blood eosinophilia, hypergammaglobulinemia, and unspecific signs of inflammation are found. Biopsy of muscle fascia gives characteristic histopathological findings of cell infiltrations (mostly mononuclear cells, frequently eosinophils) and vascular proliferation, in the middle layer of a thickened fascia. Skin changes are prevalent, but not conclusive for the diagnosis, and myositis in some patients might be difficult to distinguish from polymyositis. The importance of the clinical recognition of eosinophilic fasciitis and the inclusion of fascia in diagnostic muscle biopsies, is underlined.

Serum beta-2-microglobulin in Sjögren's syndrome.

The serum concentration of beta-2-microglobulin was determined with a radioimmunoassay in 52 patients with keratoconjunctivitis sicca, 29 of whom had Sjögren's syndrone. Eleven (38%) of the patients with Sjögren's syndrome had high serum values. These cases had a higher mean age and a higher frequency of the complete triad of Sjögren's and of antinuclear antibodies than had the lower value cases. The sicca components per se did not seem to influence the serum concentration of beta-2-microglobulin. Most of the few complications occurred in patients with high values.
