Abstract
BACKGROUND After lung transplant, 2 common complications are calcineurin inhibitor (CNI) induced nephrotoxicity and bronchiolitis obliterans syndrome. The objective of this study was to investigate the long-term effects of sirolimus conversion after lung transplantation. METHODS This was a retrospective cohort study of patients who had undergone lung transplantation at a single center from June 2003 to December 2016. We compared patients converted to a sirolimus-based regimen to those maintained on our standard tacrolimus-based regimen. Kidney function, pulmonary function, and immunosuppression concentrations were compared between the groups. Additionally, indications, toxicity monitoring parameters, and discontinuation rates for sirolimus were collected. RESULTS During the study period, 176 of the 205 patients who underwent lung transplants were converted to a sirolimus-containing regimen (86%). The most common reason for sirolimus initiation was impairment of kidney function or CNI-associated neurotoxicity. Sirolimus was initiated at a median of 150 days post-transplantation and continued for a medium time of 5.02 (2.27-7.85) years. Of those patients converted to sirolimus, 39 (22%) had sirolimus subsequently discontinued secondary to an adverse event. No difference in pulmonary function was found between the groups at 1- and 3-years post-transplantation. In the sirolimus group, the median estimated glomerular filtration rate improved by 8.6 mL/min/1.73 m2 at 3 months post-conversion (P < .001), which was maintained at both 1 and 3 years (P = .014 and .025, respectively). CONCLUSION Sirolimus is a viable immunosuppressant option after lung transplant, which successfully allows for the reduction or withdrawal of the CNI, resulting in sustained improvement in kidney function.

Abstract
Abstract
Results are reported for an interlaboratory validation study of 2 commercially available lateral flow devices (dipstick tests) designed to detect peanut residues in food matrixes. The test samples used in this study were cookies containing peanuts at 7 different concentrations in the range of 030 mg peanuts/kg food matrix. The test samples with sufficient and proven homogeneity were prepared in our laboratory. The analyses of the samples (5 times per level by each laboratory) were performed by 18 laboratories worldwide, which submitted a total of 1260 analytical results. One laboratory was found to be an outlier for one of the test kits. In general, both test kits performed well. However, some false-negative results were reported for all matrixes containing <21 mg peanuts/kg cookie. It must be stressed that the test kits were challenged beyond their cut-off limits (5 mg/kg, depending on the food matrix). One test kit showed fewer false-negative results, but it led to some false-positive results for the blank materials. The sensitivity of the dipstick tests approaches that achieved with enzyme-linked immunosorbent assays.

Abstract
During their late pulsating phase, AGB stars expel most of their mass in the form of massive dusty envelopes, an event that largely controls the composition of interstellar matter. The envelopes, however, are distant and opaque to visible and NIR radiation: their structure remains poorly known and the mass-loss process poorly understood. Millimeter-wave interferometry, which combines the advantages of longer wavelength, high angular resolution and very high spectral resolution is the optimal investigative tool for this purpose. Mm waves pass through dust with almost no attenuation. Their spectrum is rich in molecular lines and hosts the fundamental lines of the ubiquitous CO molecule, allowing a tomographic reconstruction of the envelope structure. The circumstellar envelope IRC +10 216 and its central star, the C-rich TP-AGB star closest to the Sun, are the best objects for such an investigation. Two years ago, we reported the first detailed study of the CO(2-1) line emission in that envelope, made with the IRAM 30-m telescope. It revealed a series of dense gas shells, expanding at a uniform radial velocity. The limited resolution of the telescope (HPBW 11″) did not allow us to resolve the shell structure. We now report much higher angular resolution observations of CO(2-1), CO(1-0), CN(2-1) and C4H(24-23) made with the SMA, PdB and ALMA interferometers (with synthesized half-power beamwidths of 3″, 1″ and 0.3″, respectively). Although the envelope appears much more intricate at high resolution than with an 11″ beam, its prevailing structure remains a pattern of thin, nearly concentric shells. The average separation between the brightest CO shells is 16″ in the outer envelope, where it appears remarkably constant. Closer to the star (< 40″), the shell pattern is denser and less regular, showing intermediary arcs. Outside the small (r < 0.3″) dust formation zone, the gas appears to expand radially at a constant velocity, 14.5 km s-1, with small turbulent motions. Based on that property, we have reconstructed the 3-D structure of the outer envelope and have derived the gas temperature and density radial profiles in the inner (r < 25″) envelope. The shell-intershell density contrast is found to be typically 3. The over-dense shells have spherical or slightly oblate shapes and typically extend over a few steradians, implying isotropic mass loss. The regular spacing of shells in the outer envelope supports the model of a binary star system with a period of 700 years and a near face-on elliptical orbit. The companion fly-by triggers enhanced episodes of mass loss near periastron. The densification of the shell pattern observed in the central part of the envelope suggests a more complex scenario for the last few thousand years.

Abstract
The concept of oligometastases is the medical rationale for a local treatment of a limited number of metastatic tumor manifestations. Patients with pulmonary oligometastases are candidates for surgery or radiotherapy, however there are a number of technical issues that limit treatment. Technical issues relating to radiotherapy include organs at risk of irradiation, chest wall toxicity and decreased precision of tumor targeting because of breathing movements. Technical issues relating to surgery include loss of lung parenchyma and unresectability. We propose the hypothesis that ex-vivo radiosurgery as new hybrid technique in thoracic oncology has the capability to overcome these technical issues and will expand the medical spectrum in thoracic oncology. The proposed - highly complex - technique consists of surgical lung explantation, followed by stereotactic radiotherapy during ex-vivo perfusion followed by surgical re-implantation.

Abstract
Purpose To assess efficacy of our single-centre experience with inhalative steroids (IS) in lung cancer patients with symptomatic radiation pneumonitis (RP) grade II. Material and methods Between 05/09 and 07/10, 24 patients (female, n = 8; male, n = 16) with lung cancer (non-small cell lung carcinoma [NSCLC]: n = 19; small cell lung cancer [SCLC]: n = 3; unknown histology: n = 2) and good performance status (ECOG ≤1) received definitive radiotherapy to the primary tumour site and involved lymph nodes with concurrent chemotherapy (n = 18), sequential chemotherapy (n = 2) or radiation only (n = 4) and developed symptomatic RP grade II during follow-up. No patient presented with oxygen requiring RP grade III. The mean age at diagnosis was 66 years (range: 50–82 years). Nine patients suffered from chronic obstructive pulmonary disease (COPD) before treatment, and 18 patients had a smoking history (median pack years: 48). The mean lung dose was 15.5 Gy (range: 3.0–23.1 Gy). All patients were treated with IS. If a patient’s clinical symptoms did not significantly improve within two weeks of IS therapy initiation, their treatment was switched to oral prednisolone. Results All 24 patients were initially treated with a high dose IS (budesonide 800 μg 1-0-1) for 14 days. Of the patients, 18 showed a significant improvement of clinical symptoms and 6 patients did not show significant improvement of clinical symptoms and were classified as non-responders to IS. Their treatment was switched to oral steroids after two weeks (starting with oral prednisolone, 0.5 mg/kg bodyweight; at least 50 mg per day). All of these patients responded to the prednisolone. None of non-responders presented with increased symptoms of RP and required oxygen and / or hospitalization (RP grade III). The median follow-up after IS treatment initiation was 18 months (range: 4–66 months). The median duration of IS treatment and prednisolone treatment was 8.2 months (range: 3.0–48.3 months) and 11.4 months (range: 5.0–44.0 months), respectively. Of the 18 IS treatment responders, 2 (11.1 %) patients with pre-existing grade 2 COPD still required IS (400 μg twice a day) 45.0 and 48.3 months after radiotherapy, respectively. For the remaining 16 responders (88.9 %), IS therapy was stopped after 7.7 months (range: 3.0–18.2 months). None of the patients treated with IS developed any specific IS-related side effects such as oral candidiasis. Conclusion This single-centre experience shows that high-dose IS is an individual treatment option for radiation-induced pneumonitis grade II in patients with a good performance status.

Abstract
To evaluate the adequacy of pain management in burn care, pain measurement is essential. The visual analogue thermometer (VAT) and graphic numeric rating scale (GNRS) are frequently used self-report instruments for burn pain. To legitimise their interchangeable use in research and practice, we aimed to compare self-reports obtained by the VAT and GNRS, the ability of the scales to differentiate background from procedural pain, and to compare potential cutpoints. Adults with acute burns (N=319) participated in the study (67% male, mean age 40.3 years (SD 16), mean TBSA 9.9% (SD 10.4). Correlation coefficients between VAT and GNRS were 0.64 and 0.55 for, respectively, morning and afternoon background pain and 0.51 for procedural pain (p<0.01). VAT scores were lower than GNRS scores for all pain types (p<0.01). Both scales could differentiate background from procedural pain: procedural pain was higher (p<0.01). The standardized response mean was moderate (0.518 for VAT and 0.571 for GNRS). Self-reported thresholds for 'unacceptable pain' by GNRS were higher than by VAT (p<0.001). ROC analyses showed that the highest sensitivity was reached for pain score 2 for both scales. The results suggest that the instruments cannot be used interchangeably without taking their differences into account.

Abstract
AIM To evaluate the outcome of re-irradiation and to define favourable pre-treatment characteristics. PATIENTS AND METHODS seventy-five patients with locally recurrent head and neck cancer were treated with re-irradiation, either postoperatively or as definitive treatment, with and without chemotherapy. Mean time period between first and second series of irradiation was 19 months. Mean overall dose of re-irradiation was 46 Gy. Median follow-up was 8.7 months. RESULTS Overall survival, loco-regional disease-free survival and metastasis-free survival after two years were 23%, 24% and 77%, respectively. Higher overall doses of re-irradiation gave a statistically significant better outcome with regard to overall survival (p=0.018). CONCLUSION For patients with locally recurrent head and neck cancer, re-irradiation is a feasible therapeutic option. The total dose at re-irradiation improves overall survival. Therefore, re-irradiation with curative intent should only be applied if a sufficient total dose of ≥46 Gy can be given.

Abstract
BACKGROUND Itching (pruritus) following burns is a well-known clinical problem. However, there are no long-term prospective studies that document the course and the extent of the problem. Studies on risk factors are anecdotal. OBJECTIVES To study self-reported itching in a multicentre cohort among adults with burns at 3, 12 and 24 months postburn. Further, to examine psychological and injury characteristics in relation to itching at these three points in time. METHODS Itching was assessed as part of a self-report scar complaint list in a prospective longitudinal cohort study. Injury characteristics, demographics and self-reported post-traumatic stress symptoms were examined as possible risk factors in three linear regression models. RESULTS A total of 510 persons participated. The reported prevalence rates of mild to severe itching were as high as 87%, 70% and 67% at the three respective points in time. Significant predictors of itching at all three points in time were deep dermal injury and early post-traumatic stress symptoms. Along with these, total burned surface area and female gender were predictors at 3 months postburn. CONCLUSIONS Itching remains a significant problem over a 2-year period. Individuals having undergone surgical procedures and experiencing early post-traumatic distress are more likely to suffer from long-term and persistent itching. Implications regarding practice and research are discussed.

Abstract
The aim of this study was to assess if the pain observation scale for young children (POCIS) and the visual analogue scale (VAS) are reliable and valid instruments to measure procedural and background pain in burned children aged 0-4 years. Burn care nurses (n=73) rated pain from 24 fragments of videotaped children during wound care procedures and during periods of rest using the POCIS and the VAS. Intraclass correlations were used to assess inter-rater and intra-rater reliability for the POCIS and the VAS. Internal consistency for POCIS was assessed by Cronbach's alpha. The POCIS has shown poor to moderate inter-rater reliability, moderate to good intra-rater reliability and an acceptable internal consistency. The VAS turned out to have poor inter-rater reliability and poor to moderate intra-rater reliability. Due to poor results of inter-rater reliability in both scales, construct validation is left undone until more acceptable results are obtained. Factors explaining the results are the large number of raters, the manner they were trained and a lack of variation between pain classes in video fragments. Although not all results were satisfying, an easy to use scale as POCIS has promising qualities and deserves further reliability research.

Abstract
The risk of prostate cancer is known to be elevated in carriers of germline mutations in BRCA2, and possibly also in carriers of BRCA1 and CHEK2 mutations. These genes are components of the ATM-dependent DNA damage signalling pathways. To evaluate the hypothesis that variants in ATM itself might be associated with prostate cancer risk, we genotyped five ATM variants in DNA from 637 prostate cancer patients and 445 controls with no family history of cancer. No significant differences in the frequency of the variant alleles at 5557G>A (D1853N), 5558A>T (D1853V), ivs38-8t>c and ivs38-15g>c were found between the cases and controls. The 3161G (P1054R) variant allele was, however, significantly associated with an increased risk of developing prostate cancer (any G vs CC OR 2.13, 95% CI 1.17–3.87, P=0.016). A lymphoblastoid cell line carrying both the 3161G and the 2572C (858L) variant in the homozygote state shows a cell cycle progression profile after exposure to ionising radiation that is significantly different to that seen in cell lines carrying a wild-type ATM gene. These results provide evidence that the presence of common variants in the ATM gene, may confer an altered cellular phenotype, and that the ATM 3161C>G variant might be associated with prostate cancer risk.

Abstract
The spermatocytic seminoma is a distinct testicular neoplasm with a low tendency to metastasize. Two own cases with the diagnosis of a spermatocytic seminoma are presented. A third patient is described, where the initial diagnosis of a spermatocytic seminoma was retrospectively changed to classical seminoma after developing retroperitoneal relapse during surveillance. A literature review revealed distinct histopathological characteristics and a remarkably good prognosis for spermatocytic seminoma. With only one case of relapse confirmed in the literature, in these patients postoperative treatment can safely be omitted in favor of surveillance. In case of spermatocytic seminoma diagnosis should be confirmed by a second pathologist.

Abstract
Blood relatives of patients with the inherited disease ataxia telangiectasia (A-T) have an increased susceptibility for breast cancer. We therefore looked for sequence alterations of the ATM gene in a large hospital-based series of unselected breast cancer patients. The whole ATM coding sequence was analyzed in genomic DNA samples from a core group of 192 consecutive breast cancer cases to define the spectrum of ATM gene mutations. Common sequence alterations were then screened in the whole series of 1000 breast cancer patients and in 500 random individuals. In the core group, 21 distinct sequence alterations were identified throughout the ATM coding region, and 1 common splicing mutation was uncovered in intron 10. Almost half of the breast cancer patients (46%) were heterozygotes for 1 of 16 different amino acid substitutions, and three patients (1.6%) carried a truncating mutation. These data indicate that approximately 1 in 50 German breast cancer patients is heterozygous for an A-T-causing mutation. In our extended series, the most common A-T mutation 1066-6T-->G was disclosed in 7 of 1000 (0.7%) breast cancer patients. Transcript analyses indicated that the loss of exon 11 in the ATM mRNA was the pathogenic consequence of this splicing mutation, which produced a <10% of full-length ATM mRNA and ATM protein in a homozygous A-T patient. We also found an excess of rare missense substitutions in the breast cancer cohort compared with random individuals (7.9% versus 5.3% of alleles; odds ratio = 1.6; P < 0.01). One missense substitution, S707P in exon 15, was two times more frequent in breast cancer patients (odds ratio = 2.4; 95% confidence interval, 1.0-5.8) and five times more frequent in patients with bilateral disease than in random individuals (P < 0.001). We conclude that a large variety of distinct ATM mutations and variants exist among breast cancer patients, some of which can contribute to the etiology and progression of the malignancy. Screening for frequent A-T mutations such as the 1066-6-->G splice site substitution can be effective to prospectively identify A-T heterozygotes in an unselected cancer patient population.

Abstract
Mutations of the BRCA1 or BRCA2 genes have been shown to strongly predispose towards the development of contralateral breast cancer in patients from large multi-case families. In order to test the hypothesis that BRCA1 and BRCA2 mutations are more frequent in patients with bilateral breast cancer, we have investigated a hospital-based series of 75 consecutive patients with bilateral breast cancer and a comparison group of 75 patients with unilateral breast cancer, pairwise matched by age and family history, for mutations in the BRCA1 and BRCA2 genes. Five frameshift deletions (517delGT in BRCA1; 4772delA, 5946delCT, 6174delT and 8138del5 in BRCA2) were identified in patients with bilateral disease. No further mutations, apart from polymorphisms and 3 rare unclassified variants, were found after scanning the whole BRCA1 and BRCA2 coding sequence. Three pathogenic BRCA1 mutations (Cys61Gly, 3814del5, 5382insC) were identified in the group of patients with unilateral breast cancer. The frequencies of common BRCA1 and BRCA2 missense variants were not different between the 2 groups. In summary, we did not find a significantly increased prevalence of BRCA1 and BRCA2 mutations in a hospital-based cohort of German patients with bilateral breast cancer. We conclude that bilaterality of breast cancer on its own is not strongly associated with BRCA1 and BRCA2 mutations when adjusted for age and family history. The high frequency of bilateral disease in multi-case breast cancer families may be due to a familial aggregation of additional susceptibility factors modifying the penetrance of BRCA1 and BRCA2 mutations.

Abstract
The aim of this retrospective analysis was to determine the prognostic value of the time of developing motor deficits before radiotherapy (RT) and to confirm our preliminary results by achieving statistical significance. Of 529 patients receiving spinal irradiation (1994-1998) 131 fulfilled the selection criteria. Three groups were formed according to time of developing motor deficits: 1-7 days (n = 51), 8-14 days (40), >14 days (40). Motor function was graded before, 2 weeks and 3 months after RT. After 2 weeks, patients developing motor deficits for >14 days showed improvement more often than patients of the other groups (65 versus 32.5 and 4%, p < 0.001). After 3 months results were comparable (p < 0.001). A slower development of motor deficits predicts a better functional outcome. Time of developing motor deficits before RT is a relevant prognostic factor in metastatic spinal cord compression.

Abstract
BACKGROUND Mutations of the BRCA 1/BRCA 2 genes strongly predispose towards the development of contralateral breast cancer. We therefore investigated a hospital-based series of patients with bilateral breast cancer and a comparison group of patients with unilateral breast cancer, pairwise matched by age and family history, for mutations of the BRCA 1/BRCA 2 genes. PATIENTS AND METHODS Between 1995 and 2000 genomic DNA from blood samples of 75 patients with bilateral breast cancer, who received postoperative radiotherapy, was analyzed for mutations of all coding regions and flanking intron sequences of the BRCA 1/BRCA 2 genes by single strand conformation polymorphism analysis (SSCP) and sequencing of aberrant findings. The results were compared to 75 unilateral breast cancer patients who were screened for common mutations in the BRCA 1 and BRCA 2 genes. Treatment results of patients with bilateral disease were analyzed with regard to a possible carriership of a BRCA 1/BRCA 2 gene mutation. RESULTS Five distinct frameshift deletions (one in BRCA 1, four in BRCA 2) were identified in six patients with bilateral breast cancer. Three of six carriers developed local relapse, whereas this was the case in only nine of 69 non-carriers. After radiotherapy local relapse occurred in five patients (five of 126 irradiated breasts or chest walls). Three of these patients (60%) were carriers of a pathogenic BRCA 1/BRCA 2 mutation. In the comparison group of patients with unilateral breast cancer three pathogenic BRCA 1 mutations were identified. CONCLUSIONS We failed to confirm an increased prevalence of BRCA 1/BRCA 2 mutations in our hospital-based series of patients with bilateral breast cancer. However, local relapse, especially when occurring after radiotherapy, may be predictive for an underlying pathogenic BRCA 1 and BRCA 2 gene mutation in patients with bilateral breast cancer.

Abstract
A dramatic increase of the clearing temperatures of liquid crystals based on bis(cyclohexyl)ethane 1 by 50 to 70 K can be achieved by the perfluorination of the central ethylene link. Conformational analysis indicates that this effect is due to the increased rigidity of the mesogenic core structure and to the suppression of conformers with a bent shape. Materials based on bis(cylohexyl)tetrafluoroethane 2 might play a crucial role as materials for the next generation of active matrix LCDs with reduced power consumption.

Abstract
PURPOSE In patients presented for spinal irradiation it may be difficult to distinguish between malignant and benign lesions if only plain X-rays and computed tomography (CT)-scans are available. Spinal magnetic resonance imaging (MRI) can be of great diagnostic value. METHODS From 11/1995 to 05/2000 447 patients were presented for spinal irradiation, 264 beyond regular operating hours. At presentation no spinal MRI was available in 170/447 and 132/264 patients. RESULTS After spinal MRI, diagnosis was changed from vertebral metastases to spondylodiscitis in 10/170 and 8/132 patients. Six of these patients were already known as cancer patients. CONCLUSION In patients presented for spinal irradiation spondylodiscitis is not very uncommon. If there is any doubt about metastatic disease as the cause for spinal cord compression a spinal MRI has to be demanded, even beyond regular operating hours.

Abstract
UNLABELLED Lysophosphatidic acid (LPA) is an intercellular phospholipid mediator with a variety of actions that suggest a role in stimulating inflammatory responses. We therefore studied its actions on neutrophil (PMN) motility and respiratory burst. Because local anesthetics (LA) inhibit LPA signaling and attenuate PMN responses, we also investigated the effects of LA on these actions. Chemotaxis of human PMNs under agarose toward LPA (10(-10)-10(-3) M) was studied, with and without 1 h prior incubation in lidocaine (10(-9)-10(-4) M). Priming as well as activating effects of LPA on PMNs were measured using a cytochrome-c assay of superoxide anion (O2-) production. PMNs were incubated with lidocaine, tetracaine, or S-(-) ropivacaine (all at 10(-6)-10(-4) M) for 10 min or 1 h to assess interference with LPA signaling. LPA demonstrated chemoattractive effects towards human PMNs; this effect was concentration-dependently attenuated by lidocaine. LPA alone did not activate PMNs. However, it acted as a priming agent. LA in clinically relevant concentrations decreased (O2-) production induced by LPA/N-formylmethionine-leucyl-phenylanaline. LPA acts as a chemoattractant and priming agent; however, it does not activate PMNs. LA, in clinically relevant concentrations, attenuate chemotactic and metabolic responses as a result of LPA. These results may explain the antiinflammatory effect of local anesthestics. IMPLICATIONS Lysophosphatidic acid (LPA) influences two functions of human neutrophils, migration and metabolic activity. It acted as a chemoattractant and a priming-but not activating-agent. Responses to LPA were attenuated by local anesthetics in clinically relevant concentrations.

Abstract
To minimize anaesthesia related risks during craniospinal irradiation in children, treatment in supine position would be preferable. Verification especially of the cervical three-field junction causes problems, because direct visual control is not possible. We present clinical experiences with a new verification technique with all three fields exposed on one single film.
