Abstract
Climate change and other global change drivers threaten plant diversity in mountains worldwide. A widely documented response to such environmental modifications is for plant species to change their elevational ranges. Range shifts are often idiosyncratic and difficult to generalize, partly due to variation in sampling methods. There is thus a need for a standardized monitoring strategy that can be applied across mountain regions to assess distribution changes and community turnover of native and non‐native plant species over space and time. Here, we present a conceptually intuitive and standardized protocol developed by the Mountain Invasion Research Network (MIREN) to systematically quantify global patterns of native and non‐native species distributions along elevation gradients and shifts arising from interactive effects of climate change and human disturbance. Usually repeated every five years, surveys consist of 20 sample sites located at equal elevation increments along three replicate roads per sampling region. At each site, three plots extend from the side of a mountain road into surrounding natural vegetation. The protocol has been successfully used in 18 regions worldwide from 2007 to present. Analyses of one point in time already generated some salient results, and revealed region‐specific elevational patterns of native plant species richness, but a globally consistent elevational decline in non‐native species richness. Non‐native plants were also more abundant directly adjacent to road edges, suggesting that disturbed roadsides serve as a vector for invasions into mountains. From the upcoming analyses of time series, even more exciting results can be expected, especially about range shifts. Implementing the protocol in more mountain regions globally would help to generate a more complete picture of how global change alters species distributions. This would inform conservation policy in mountain ecosystems, where some conservation policies remain poorly implemented.

Abstract
Context Infrastructure development in ski-resort areas has led to the modification of slopes and, often, the replacement of native plant species with exotic grasses. Modified ski slopes are effectively linear areas of disturbance that separate natural habitat and provide barriers to the movement of native animal species. To overcome these barriers, boulder-filled and culvert-style wildlife crossings have been constructed across disturbed ski slopes and under roadways to facilitate the movement of small native mammal species among areas of remnant habitat, but generally they differ in size and locality. The use of boulder-filled and under-road culvert crossings of different length has not been evaluated. Aims We determine whether fauna utilise wildlife crossings in ski resorts and whether variations in crossing length influence the species using the crossings. Methods We monitored boulder-filled crossings of two size classes (long or short) biannually from March 2009 to April 2013, using hair tubes. We monitored an additional two under-road culvert crossings with remote infrared cameras. Key results The results indicated that all crossings, regardless of size, are utilised by small mammals. However, we detected threatened species, such as Mastacomys fuscus (broad-toothed rat), more frequently in crossings of greater length. Conclusions To maintain linkages for small-mammal populations within ski resorts, we recommend the continued use of boulder-filled crossings on ski slopes. These crossings may be particularly important in facilitating the movement of small mammals across wide areas of ski-slope disturbance. Implications The context and maintenance of crossings is likely to be important for their long-term use by small mammals, as are complementary strategies to restore structural habitat connectivity on ski slopes, such as strategically implemented native vegetation plantings.

Abstract
Although induction chemotherapy prior to local therapy produces encouraging initial response rates in head and neck cancer, randomized studies have failed to demonstrate an advantage in survival. All randomized studies included only patients with far advanced stage III and IV disease which appears to be the main reason for the low rate of complete responses (max. 18%) in these trials. According to statistical considerations nearly 50% complete responders are necessary before improved survival benefit can be expected. Until now, such complete response rates are only achieved with induction chemotherapy in resectable T2-T3, N0-N2 disease. Therefore, we started a prospective randomized trial including only patients with these stages of disease. Patients were stratified by primary tumor site and neck node status and were randomized to receive either induction chemotherapy with three cycles of carboplatin/5-FU prior to surgery and radiotherapy (arm A, 49 patients) or standard treatment with surgery and radiotherapy (arm B, 47 patients). Patients were stratified by primary tumor site and neck disease. After a follow-up of 12-48 months overall survival was 72% in arm A and 53% in arm B (n.s.). Considering only the patients with cancer of the oral cavity and the tonsil overall survival was 88% in arm A and 44% in arm B (p<0.05). As of today, the number of patients with carcinomas of the hypopharynx and base of tongue is too small for a statistically significant statement, but preliminary data indicate a better overall and disease-free survival without chemotherapy in these patients. Therefore, we recommend controlled trials with induction chemotherapy in patients with primary resectable carcinomas of the oral cavity and the tonsil, stages T2-T3 and N0-N2, prior to surgery but not in patients with cancer of the hypopharynx and base of the tongue.

We replaced Doppler-derived stroke volume in the continuity equation (method A) by either right heart catheterization-derived stroke volume (method B) or cardiovascular magnetic resonance-derived stroke volume (method C) to calculate aortic valve area in 20 consecutive patients with moderate or severe aortic stenosis. Comparison of both hybrid methods (methods B and C) by Bland-Altman analysis showed a mean difference near zero, a spread within two standard deviations and very similar limits of agreement. More importantly, all patients were classified into the same category of severity by both methods.

Abstract
OBJECTIVE To determine the relative bioavailability and plasma paracetamol concentration profiles following administration of a proprietary formulation of paracetamol suppositories to postoperative children. METHODOLOGY AND RESULTS Study A-eight children undergoing minor surgery had blood samples collected following the rectal administration of either a 250 mg or 500 mg paracetamol suppository on one day and an equivalent oral dose on the following day. A mean dose of 13 mg/kg gave a mean Cmax (Tmax) of 7.7 mg/L (1.6 h) and 4.9 mg/L (2.0 h) following oral and rectal administration, respectively. The mean relative rectal bioavailability was 78% (95% confidence interval of 55-101%). Study B-20 children undergoing tonsillectomy and/or adenoidectomy were randomly assigned to receive a postoperative dose of 500 mg of paracetamol either as 2 x 250 mg liquid filled or 1 x 500 mg hard wax Panadol suppository. A mean dose of 25 mg/kg produced mean maximum plasma paracetamol concentrations of 13.2 mg/L and 14.5 mg/L at 2.1 and 1.9 h for the hard and liquid filled suppository, respectively. The absorption rate constants and areas under the curves suggested no difference in the rate or extent of absorption between the two formulations. CONCLUSION Absorption of paracetamol following rectal administration of Panadol suppositories to postoperative children is slower and reduced as compared to oral therapy. The hard wax and liquid filled products have similar absorption characteristics. The usually quoted antipyretic therapeutic range for paracetamol is 10-20 mg/L, although 5 mg/L may be effective. A single rectal dose of 25 mg/kg will obtain this lower concentration within 1 h of administration and maintain it for up to 6 h. When given in an appropriate dose for analgesia, maximum plasma paracetamol concentrations would be available in the immediate postoperative period if the rectal dose was given 2 h before the planned end of the procedure.

Abstract
The authors studied the intelligence, memory, visuomotor skills and la nguage of 298 six-year-old children with very low birthweight (VLBW) (less that 1500g). Of 591 VLBW childern born July 1983 to June 1986 within 50km of the centre of Hamburg, Germany, 330 were traceable at age six years and 298 of these were seen by a neuropaediatrician and a psychologist; the other 19 were too severely disabled for psychological assessment with the standardized tests used. The mean memory performance of VLBW children at age six years was below the standard mean in all diagnostic and socio-economic subgroups. As expected, visuomotor development was clearly influenced by neurological but not socio-economic status. Intelligence and language skills were much more closely related to socio-economic background that to neurological morbidity. However, VLBW children with hyperactivity, clumsiness or cerebral palsy differed significantly in intelligence and visuomotor performance from those without neurological symptoms.

Abstract
Three patients suffering from gustatory sweating following trauma to the preauricular region from a bullet wound or parotid gland surgery were treated by intracutaneous injection of botulinum toxin A. Within 2 weeks, gustatory sweating in the area injected completely ceased in all patients with no side-effects. The efficacy of treatment was confirmed by repeated Minor's iodine starch tests. So far, sweating has not recurred during a follow-up period of up to 8 months. Botulinum toxin appears to be a promising new drug for the treatment of this autonomic disorder.

Abstract
In 26 patients we performed an arthroscopically assisted arthrodesis of the ankle. The patients' ages ranged from 31 to 69 years. The male:female ratio. Sixteen patients had posttraumatic degenerative joint disease, three patients suffered from a previous infection, four patients had rheumatoid arthritis, and three patients had an osteochondritis dissecans in their past history. The time taken for surgery ranged from 65 to 135 min. Compared with open procedures we documented less postoperative swelling and minor use of analgesics. Time of follow-up was a minimum of 6 months and a maximum of 75 months. In 22 patients we found solid fusion at the time of followup. Fusion was accomplished by 2 months postoperatively in four patients, by 3 months in nine patients, by 4 months in another six patients, and by 6 months in 3 patients. Three patients did not evidence any bony fusion, but they were free of pain. In one patient an open revision was necessary. According to our experience, we recommend arthroscopically assisted arthrodesis of the ankle in patients with degenerative joint disease without rotational or varus/valgus malalignment, severe bone defects or neuropathic disease.

Abstract
In 29 patients with persistent complaints after knee replacement we found intra-articular fibrous tissue in different areas of the joint. In 26 patients diagnostic arthroscopy was followed by arthroscopic resection of the tissue. The fibrous tissue was differentiated into five types. Type 1 represented a transverse fibrous band located at the superior margin of the femoral component of the prosthesis. A type 2 plica was a lateral plica extending from the superolateral border of the patella to the infrapatellar fat pad. The type 3 fibrous band reached from the inferior pole of the patella to the intercondylar area. The type 4 nodulus was located at the superior border of the patella, and the type 5 plica was a meniscoid-like tissue between the femoral and the tibial component. Arthroscopic resection resolved the symptoms in 25 of the patients. Different factors seem to contribute to the development of intra-articular plicae after knee alloarthroplasty.
