- The epidemiology of neuromuscular diseases was studied in the county of Orebro, Sweden (study population 270,000). Several different sources of data were utilized, compared and validated. On the prevalence of day (January 1, 1988) 474 patients were identified. The rate per 100,000 population was 92 for the postpolio sequelae (PPS) and 84 for the other neuromuscular diseases (motor neuron disease 9, hereditary neuropathies 9, myoneural disorders 16, myotonic disorders 19, muscular dystrophies 20 and myositis 11). Of the patients with the PPS, 80% reported late-onset symptoms. On the basis of an expanded survey including all medical records in one health care district, the prevalence of the PPS was estimated to be 186/100,000 population.

- Few well-validated self-and/or parent-administered instruments are available for measuring functional status in children with rheumatic diseases. Parts of the Stanford Health Assessment Questionnaire (HAQ) have been adapted for use in children in the so-called Child HAQ. The aim of this study was to investigate the validity of this instrument in a Swedish setting. The Child HAQ was administered to 186 patients and 211 patients participating in a population-based follow-up study of juvenile chronic arthritis (JCA) in southwestern Sweden. The EULAR criteria were used for inclusion. Children who were 9 years of age or older self-reported. Reliability, evaluated by test-retest, inter-observer correlations and internal reliability, was excellent. Convergent validity was demonstrated by strong correlations of the disability index, pain, and morning stiffness with disease activity and the Steinbrocker functional classes. Discriminant validity was evidenced by the capacity of the instrument to evaluate patients as being active or in remission. Thus, the Child HAQ showed excellent measurement performance in a Swedish setting when using parents or children more than 9 years old as responders.

- Two distinct phosphorylated intermediates representing the Ca2+-ATPase and H+-ATPase, respectively, were detected after phosphorylation of plasma membranes from cauliflower (Brassica oleracea L.) inflorescences with [gammaP-32]ATP and separation of polypeptides in an acidic gel. A 116 kDa polypeptide was identified as a Ca2+-ATPase by its Ca2+-dependent phosphorylation which was enhanced by La3+. A second polypeptide (105 kDa) also phosphorylated in the absence of Ca2+ and was identified as the H+-ATPase by immune blotting.

- Previous in vitro studies have suggested that tetracycline‐HCl (TTC‐HCl) is adsorbed and actively released from root dentin. The aim of the current study was to evaluate the binding to and release of TTC‐HCl from human root dentin surfaces in vivo, and to evaluate the clinical utility of TTC‐HCl irrigation as an adjunct to scaling and root planing. Experiment I utilized two contralateral mandibular single‐rooted teeth which were examined in four adults with severe generalized periodontitis. One tooth in each patient was carefully scaled and root planed, under local anesthesia, and the other used as an unsealed control. Each subgingival root surface was irrigated for 5 min with an aqueous TTC‐HCl solution at a concentration of 100 mg/ml. Gingival crevicular fluid samples were collected on paper strips for the next three weeks. The TTC‐HCl concentrations in each sample were determined by the inhibition zone of B. cereus cultured on agar plates. The TTC‐HCl concentrations in gingival crevicular fluid collected 15 min after irrigation were 3100±670 μg/ml from the scaled lesions and 4700±1300 μg/ml from the unsealed root surfaces. The antibiotic concentrations decreased logarithmically over the next 7 days; 1500±270 μ/g/ml and 1100±330μ/g/ml at 2 h. 880±350μ/g/ml and 1300±360 μ/g/ml at 6 h and 19±5μ/g/ml and 31±26 μ/g/ml at 1 week for scaled and unsealed root surfaces, respectively. Results for week two and three indicated an average of over 8 μg/ml. The TTC‐HCl concentrations in gingival crevicular fluid from scaled and unsealed root surfaces were not statistically different at any time point. The tetracycline irrigation resulted in release of tetracycline at concentrations well above therapeutic concentrations for at least 1 week. Experiment II comprised 11 patients with severe adult periodontitis. All subjects were scaled and root planed prior to baseline measurements. The patients were monitored by the following parameters: probing pocket depth (PPD), probing attachment level (PAL), gingival index (GI) and plaque index (PI). 54 contralateral teeth exhibiting residual pocket depths of 5 mm were selected. Within each pair identified for the study, teeth were randomly assigned as test or control sites. After baseline measurement, each subgingival root surface was irrigated for 5 min; either with an aqueous TTC‐HCl solution of 100 mg/ml (test), or a 0.9% NaCl solution (control). At 3 and 6 months post‐treatment, the PI was unchanged for both groups. The GI index was reduced (0.062 > p > 0.001) in a similar manner for both groups. PPD showed statistically significant (p < 0.001) mean/patient decrease of similar magnitudes, 2.3±1.0 mm (test), and ‐1.6±0.8 mm (control) at 3 months, and ‐2.1±1.1 mm (test), and ‐1.4±0.9 mm at 6 months (control), respectively. Also, PAL measurements indicated a statistically significant average gain/patient of 2.1±1.1 mm in the test group (p<0.00l) and again of 1.2±1.0 mm in the controls (p = 0.002) at 3 months, and 1.8±1.1 mm (test; p<0.001) and 1.0±0.9 mm (controls; p= 0.005) at 6 months. Comparisons of the changes, between the groups, indicated statistically greater gain of PAL in the test group at both the 3 (p= 0.042) and 6 months (p= 0.034) intervals. These results suggest that TTC‐HCl irrigation of root surfaces for long periods of time (5 min) results in a subsequent release of active antibiotic into the gingival fluid at therapeutic levels for at least 1 week. TTC‐HCl irrigation resulted in significantly greater attachment gain as compared to scaling and root planing alone over at least a month period of healing.
