    Notes: Abstract. It is shown in this Comment that the method proposed by Zhiwei et al. to extract cross sections for collisional energy transfer between molecular states mediated by argon atoms, is neither correct nor suitable, as it fails to reproduce the molecular behaviour they observe. An alternative model based on a consecutive scheme is put forward, and it is shown that a minimal assumption of one intermediate collisionally activated step is enough to satisfactorily reproduce the observations by Zhiwei et al. However, the extracted parameters are functions of the involved rate constants that are too complex to leave any hope of attaining information on the desired cross sections from them by just varying the argon buffer gas pressure, as done by Zhiwei et al.

    Notes: The objective of the study was to investigate whether intensified rehabilitation efforts in primary health care may produce any short-term or long-term reduction of sick leave. The resources at the health care center were fortified with a coordinator from the local insurance office and a specialist group from the hospital. In one primary health care district, a prospective study was performed among 100 patients with a musculoskeletal disorder, having caused at least 21 consecutive days of full-time sick leave (patients). Serving as a control group were individually matched patients from any other health care center in the surrounding municipality of Kristianstad (controls). The number of sick leave days was assessed during year one (short-term) and year three (long-term) after rehabilitation was initiated. The median number of days with sickness benefits for men in the short-term was lower for patients than for controls (34.5 vs 48.5). No difference was found among women. No differences were found in the long-term between patients and controls, either for men or women. We conclude that rehabilitation in primary health care was made more efficient through collaboration with the local insurance office and the specialists, but the effects were not maintained after the collaboration ended.

    Notes: Background Immune-mediated food hypersensitivity affecting the gut is difficult to evaluate, and objective tools to diagnose local gastrointestinal (GI) inflammatory reactions are lacking.Objectives To determine whether allergic manifestations in adults with a history of food-related GI symptoms could be assessed in feces during symptomatic and non-symptomatic periods, using the surrogate markers, eosinophil cationic protein (ECP), eosinophil protein X (EPX) and myeloperoxidase (MPO).Methods Thirteen subjects with food hypersensitivity-related GI symptoms, confirmed by a positive double-blind placebo-controlled food challenge (DBPCFC), were subjected to an open kinetic food challenge design for 6 weeks. Symptoms were recorded and scored during the 3-week study period and stool samples were obtained every day. The surrogate markers ECP, EPX and MPO were measured in the supernatants from feces samples.Results A significant increase in abdominal pain, distension and flatulence was observed during challenge, with a gradual decrease during elimination diet. Both between days and subjects, EPX levels were more frequently increased compared to ECP and MPO. Individuals with a history of a short duration of symptoms had significantly higher mean levels of EPX and MPO than those with a longer duration of symptoms.Conclusions An overall increase in levels of eosinophil markers, in particular EPX, was observed in feces from patients with food-related GI symptoms. However, rather than being a tool to differentiate symptomatic from non-symptomatic periods, EPX might be used for detecting an ongoing clinical or subclinical chronic inflammation, that may have an impact on the patient's clinical course of GI symptoms.

    Notes: Sixty patients, clinically examined for TMJ dysfunction, were also electromyographically screened. The TMJ dysfunction pain in forty patients was evaluated to be mainly of a myogenous origin and in fourteen patients of a mainly arthrogenous origin. Due to lack of findings in the clinical examination six patients were not to be classified into either of the two groups. They were excluded from the EMG study. For the EMG examination the patients were asked to clench for 30 s in the intercuspal position at 50% of the maximum EMG activity of the masseter muscles. Surface electromyograms of the right and the left masseter and anterior part of the temporalis muscles were monitored. The amplitude of the EMG signal, the duration of the silent period and the changes in the frequency composition of the signal during the 30 s contraction were analysed.Statistically significant differences between the two patient groups were found in EMG amplitude and in silent period duration. However, the difference in silent period duration was due to the dependency of the silent period on the activation level of the muscle. No statistically significant difference in silent period was found when this dependency was corrected for in the data. The EMG parameters related to muscular fatigue phenomena did not show any difference between the two groups.The difference in EMG amplitude and consequently the difference in silent period duration support the clinically made distinction into mainly a myogenous or mainly an arthrogenous origin of TMJ dysfunction pain.

    Notes: Two hundred and twenty-two patients who had been examined and treated for craniomandibular disorders were re-evaluated using a screening protocol. This protocol was developed from previous studies which had elucidated the most reliable signs and symptoms of craniomandibular disorders. Unilateral signs and symptoms were found to be more common than bilateral signs and symptoms. Dynamic and static pain tests were shown to be decisive in determining the preliminary diagnosis. There was a significant difference in vertical condylar height asymmetry between those patients diagnosed as having a myogenous and an arthrogenous origin of pain.

    Notes: A comparison between clinical, tomographical, and dental panoramic radiographical findings was made in thirty-one female patients suffering from craniomandibular disorders (CMD). In general it was found that condylar sclerosis was more common in these patients than in earlier studies. After clinical separation of the material into two groups based upon the origin of pain, myogenous versus arthrogenous, no radiographical confirmation of the differential diagnostics could be made. Regarding vertical condylar asymmetry measured on the Orthopantomogram®, it was found that 74% of the patients with CMD had more than the 3% of asymmetry regarded as within normal limits. It seems that with an increasing severity of the disorder the level of condylar asymmetry appears less. If the interpretation of the findings is correct its conclusion might lead to the recognition of a morphological factor which could contribute to the development of a craniomandibular disorder.

    Notes: Vertical measurements of the Orthopantomogram® of 152 patients were made for condylar and rami heights. The symmetry between the right (R) and the left (L) side was calculated with the formula: |(R−L)/(R+L)|. A statistically significant difference between the patients of a routine dental group and the patients treated for craniomandibular disorders was found regarding condylar height symmetry.

    Notes: As an orthopantomogram provides bilateral information, it seems to be an efficient tool for screening for arthropathy of craniomandibular disorders. An experimental model was designed and constructed to resemble a human mandible. By changing the position of the model in the horizontal plane of the orthopantomograph, nine different images were analysed for changes of vertical magnifications. Emphasis was put on large parts of the mandible like the condyle. In positions that had been altered less than 10 mm from the originally centred position of the mandible in the orthopantomograph, vertical differences between the left and right sides were less than 6%. Observed condylar asymmetries within a 6% difference might, therefore, be due to technical failures.

    Notes: Macroscopic features of temporomandibular joints (TMJs) were studied in young adults who comprise the largest portion of individuals seeking TMJ treatment. Deviation in form (DIF), arthrosis, size, shape and disc displacement were evaluated on ninety-five autopsied TMJs. Few TMJs (13%, 12/95) showed no intracapsular changes. Thirty-nine per cent (37/95) of the TMJs displayed mild-to-marked DIF in all three TMJ components. Smaller changes were more prevalent and tended to appear in the younger TMJs. Condylar changes were more exuberant and extensive compared to the other components. Minor arthrotic lesions were visible in 3% (3/95), and all displayed DIF. Disc displacement was found in 12% (11/95) and was more common in women (P 〉 0.05). Folding and deformation of the articular disc was associated with disc displacement (P 〈 0.01), the direction of which was mostly anteromedial. Most of the unchanged condyles' components had curved, slightly rounded, convex, and elliptical shapes when viewed from different planes (P 〈 0.01). Applied in diagnosis, the presence of DIF can be inferred from features which deviate from the above shapes. The concept that the above macroscopic changes might be a precursor to TMJ arthropathy in susceptible individuals is compatible with the results of this study, but the most apt characterization is that TMJ changes in this age group are adaptive phenomena occurring in order to cope with the details of articular fit and function.
