Abstract
An Indian migrant presented with increasing neurological symptoms after an acute influenza B infection. We diagnosed progressive neurotuberculosis—a rare and difficult case of tuberculosis and influenza co-infection. It highlights the importance of broad-based diagnostics in people from low- and middle-income countries, taking into account unusual manifestations of tuberculosis.

Abstract
Chemotherapy-induced peripheral neuropathy (CIPN) is a prevalent and clinically relevant side effect of chemotherapy. The symptoms diminish patients' quality of life and represent a decisive limiting factor for medical therapy. To date, effective treatment options are lacking. Specific exercise interventions have proven promising to target relevant symptoms. We conducted a prospective, four-armed, randomized, controlled trial, to evaluate the effects of sensorimotor training (SMT) and whole-body vibration training (WBV) on patients with CIPN. Participants (N = 40) were randomized to either one of two intervention groups (SMT N = 10 or WBV N = 10) or oncological control group (N = 10) and matched by gender and age with a healthy control (N = 10). The intervention groups exercised twice a week for 6 weeks. Primary endpoint was the reduction of CIPN-related symptoms (improve peripheral deep sensitivity, Achilles tendon reflex (ASR) and patellar tendon reflex (PSR), light-touch perception, sense of position, and lower leg strength). Secondary endpoints were nerve conduction velocity and amplitude, balance control, quality of life, and CIPN-related pain. Patients exercising improved sensory and associated motor symptoms. Significant intergroup differences were found for the tendon reflexes (ASR P = .017 and PSR P = .020), peripheral deep sensitivity (P = .010), and pain (P = .043). Furthermore, tendencies were found regarding the subjective improvement of symptoms (P = .075) and two subscales of the EORTC-QLQ-C30 questionnaire: pain (P = .054) and dyspnea (P = .054). The results for the SMT group were superior regarding the tendon reflexes, and a tendency regarding the subjective report of symptoms, while WBV was superior regarding pain. SMT and WBV behold a large potential to reduce CIPN-related symptoms and can be considered feasible and safe for patients with CIPN (compliance 97.5%, no adverse events).Registration: DRKS00013027.

Abstract
PURPOSE The reliability of the Rockwood classification, the gold standard for acute acromioclavicular (AC) joint separations, has not yet been tested. The purpose of this study was to investigate the reliability of visual and measured AC joint lesion grades according to the Rockwood classification. METHODS Four investigators (two shoulder specialists and two second-year residents) examined radiographs (bilateral panoramic stress and axial views) in 58 patients and graded the injury according to the Rockwood classification using the following sequence: (1) visual classification of the AC joint lesion, (2) digital measurement of the coracoclavicular distance (CCD) and the horizontal dislocation (HD) with Osirix Dicom Viewer (Pixmeo, Switzerland), (3) classification of the AC joint lesion according to the measurements and (4) repetition of (1) and (2) after repeated anonymization by an independent physician. Visual and measured Rockwood grades as well as the CCD and HD of every patient were documented, and a CC index was calculated (CCD injured/CCD healthy). All records were then used to evaluate intra- and interobserver reliability. RESULTS The disagreement between visual and measured diagnosis ranged from 6.9 to 27.6 %. Interobserver reliability for visual diagnosis was good (0.72-0.74) and excellent (0.85-0.93) for measured Rockwood grades. Intraobserver reliability was good to excellent (0.67-0.93) for visual diagnosis and excellent for measured diagnosis (0.90-0.97). The correlations between measurements of the axial view varied from 0.68 to 0.98 (good to excellent) for interobserver reliability and from 0.90 to 0.97 (excellent) for intraobserver reliability. CONCLUSION Bilateral panoramic stress and axial radiographs are reliable examinations for grading AC joint injuries according to Rockwood's classification. Clinicians of all experience levels can precisely classify AC joint lesions according to the Rockwood classification. We recommend to grade acute ACG lesions by performing a digital measurement instead of a sole visual diagnosis because of the higher intra- and interobserver reliability. LEVEL OF EVIDENCE Case series, Level IV.

Abstract
BACKGROUND The use of interference screws for femoral graft fixation in anterior cruciate ligament (ACL) reconstruction with hamstring grafts can result in rotation of the graft around the screw leading to changes in the final position of the graft within the bone tunnel. MATERIAL AND METHODS In a prospective study 107 patients (54 right and 53 left knees) underwent ACL reconstruction with a hamstring tendon autograft. Femoral fixation of the graft was performed with a standard right-thread screw in all cases. Patients were assessed at 6 months postoperatively with the international knee documentation committee (IKDC) standard evaluation including instrumented laxity measurements and the results were compared between right and left knees. RESULTS A significantly higher postoperative anterior laxity was observed in left knees with a negative Lachman test in only 64 % of the cases compared with 87 % in the group of right knees. Accordingly, instrumented laxity measurements of the reconstructed knee compared with the contralateral knee revealed significant differences between left and right knees (left knees 1.8±1.2 mm and right knees 1.0±1.4 mm). CONCLUSIONS This study demonstrates the importance of femoral graft positioning and its sensitivity to multiple influencing factors. The use of standard right-thread interference screws for femoral graft fixation in the mirrored situation of right and left knees may produce a systematic error in ACL reconstruction. Due to a possible rotation of the graft around the screw, the final position of the transplant may vary thus leading to significant changes in anterior translation of the operated knee.

Abstract
The aim of this study was to define the treatment criteria for patients with recurrent chondrosarcoma. We reviewed the data of 77 patients to examine the influence of factors such as the intention of treatment (curative/palliative), extent of surgery, resection margins, status of disease at the time of local recurrence and the grade of the tumour. A total of 70 patients underwent surgery for recurrent chondrosarcoma. In seven patients surgery was not a viable option. Metastatic disease occurred in 41 patients, appearing synchronously with the local recurrence in 56% of cases. For patients without metastasis at the time of local recurrence, the overall survival at a mean follow-up after recurrence of 67 months (0 to 289) was 74% (5 of 27) compared with 19% (13 of 50) for patients with metastasis at or before the development of the recurrence. Neither the type/extent of surgery, site of tumour, nor the resection margins for the recurrent tumour significantly influenced the overall survival. With limited survival for patients with metastatic disease at the time of local recurrence (0% for patients with grade III and de-differentiated chondrosarcoma), palliative treatment, including local radiation therapy and debulking procedures, should be discussed with the patients to avoid long hospitalisation and functional deficits. For patients without metastasis at the time of local recurrence, the overall survival of 74% justifies an aggressive approach including wide resection margins and extensive reconstruction.

Abstract
AIM To investigate the prevalence of urticaria with a focus on chronic urticaria (CU) in a general German population. METHODS A questionnaire survey was sent to a representative cross-sectional sample of 13,300 inhabitants of Berlin, Germany, of whom 4093 responded. All respondents who stated ever having had weals or angio-oedema (n=767) were interviewed by telephone. Any interviewees with recent symptoms (within the previous 3 years) were invited for personal investigation including allergy tests; double-blind, placebo-controlled food challenge tests; and quality of life (QOL) assessment. Reported prevalence rates were weighted with regard to age, gender and education so that they were representative of the total population of Berlin. RESULTS Lifetime prevalence rate of urticaria was 8.8% (95% CI 7.9-9.7%) for all types of urticaria. Lifetime prevalence for CU was 1.8% (95% CI 1.4-2.3%), and prevalence for the 12 months before assessment was 0.8% (95% CI 0.6-1.1%), and 70.3% were female. QOL was markedly reduced for people with CU. Unlike other allergic diseases, there was no increased risk associated with higher education or social status. Prick tests found sensitization of ≥ 1 for type 1 allergens in 39.1% of patients. These were related to comorbidities such as allergic rhinitis or oral allergy syndrome, but were never the underlying cause of CU, as proven by double-blind, placebo-controlled provocation tests. CONCLUSION Urticaria is a common disease with marked effects on QOL. The lifetime prevalence of 8.8% for urticaria must be regarded as a lower limit as it is based on conservative prevalence rate calculations, and under-reporting of previous disease can be expected in a questionnaire-based study.

Abstract
There is clinical evidence that a standardized management of trauma patients in the emergency room improves outcome. ATLS is a training course that teaches a systematic approach to the trauma patient in the emergency room. The aims are a rapid and accurate assessment of the patient's physiologic status, treatment according to priorities, and making decisions on whether the local resources are sufficient for adequate definitive treatment of the patient or if transfer to a trauma center is necessary. Above all it is important to prevent secondary injury, to realize timing as a relevant factor in the initial treatment, and to assure a high standard of care. A standard operating procedure (SOP) exactly regulates the approach to trauma patients and determines the responsibilities of the involved faculties. An SOP moreover incorporates the organizational structure in the treatment of trauma patients as well as the necessary technical equipment and staff requirements. To optimize process and result quality, priorities are in the fields of medical fundamentals of trauma care, education, and fault management. SOPs and training courses increase the process and result quality in the treatment of the trauma patient in the emergency room. These programs should be based on the special demands of the physiology of the trauma as well as the structural specifics of the hospital. ATLS does not equal an SOP but it qualifies as a standardized concept for management of trauma patients in the emergency room.

Abstract
The six extant aquatic families of Hydradephaga (Coleoptera) known so far represent a diverse group of beetles morphologically highly modified for life in the water. We report the discovery of a new genus with two species from South Africa and China, which differ greatly from all extant families, but resemble the Jurassic-Cretaceous dagger Liadytidae (the dagger symbol indicates that the taxa are known only as fossils). Based on a combined phylogenetic analysis of molecular and morphological data we erect a new family, Aspidytidae, which is the sister group of Dytiscidae plus Hygrobiidae. We propose a new scenario for the evolution of swimming behaviour in adephagan beetles, in which the transition into the aquatic environment is followed by complex and repeated changes in lifestyles, including the secondary complete loss of swimming ability in Aspidytidae.

Abstract
Only one species of Hydroporini, Megaporus piceatus (RCgimbart, 1892), has been known from New Guinea. M. piceatus is very similar to the Australian M. ruficeps (Sharp, 1882) and study of additional material is neccessary to determine its status. Chostonectes maai, sp. nov., is described from Papua New Guinea. Its sister-species is the Australian C. gigas (Boheman, 1858). The classification of the genera Megaporus Brinck, 1943, and Chostonectes Sharp, 1882, is discussed, and autapomorphies for both groups are suggested. The following species of Hydroporini are reported from New Guinea for the first time: Megaporus sp., Antiporus sp., and Sternoprisccts hansardi (Clark, 1862). A total of five Hydroporini species is now known from New Guinea. All are Australian, or of Australian origin. The New Guinean Hydroporini are not a monophyletic group. The factors delimiting the distribution of Hydroporini in New Guinea are climate and perhaps also vegetation. Australian Hydroporini are adapted to a seasonal climate and most of them also to open forests/woodland.
