Abstract
Background Cultural sensitivity (CS) training is vital to pediatric emergency medicine (PEM) curricula. This study aimed to explore CS in Yale PEM fellows and emergency medicine (EM) residents at Indus Hospital and Health Network (IHHN) in Pakistan through distance simulation activities. Methods This mixed-methods analysis of an educational intervention was conducted at Yale University in collaboration with IHHN. We approached seven U.S. PEM fellows and 22 Pakistani EM residents. We performed a baseline CS assessment using the Clinical Cultural Competency Questionnaire (CCCQ). Afterward, the U.S. PEM fellows facilitated the Pakistani EM residents through six distance simulation sessions. Qualitative data were collected through online focus groups. The CCCQ was analyzed using descriptive statistics, and content analysis was used to analyze the data from the focus groups. Results Seven U.S. PEM fellows and 18 of 22 Pakistani EM residents responded to the CCCQ at the beginning of the module. The mean (±SD) CCCQ domain scores for the U.S. PEM fellows versus the Pakistani EM residents were 2.56 (±0.37) versus 2.87 (±0.72) for knowledge, 3.02 (±0.41) versus 3.33 (±0.71) for skill, 2.86 (±0.32) versus 3.17 (±0.73) for encounter/situation, and 3.80 (±0.30) versus 3.47 (±0.47) for attitude (each out of 5 points). Our qualitative data analysis showed that intercultural interactions were valuable. There is a common language of medicine among the U.S. PEM fellows and Pakistani EM residents. The data also highlighted a power distance between the facilitators and learners, as the United States was seen as the standard of "how to practice PEM." The challenges identified were time differences, cultural practices such as prayer times, the internet, and technology. The use of local language during debriefing was perceived to enhance engagement. Conclusion The distance simulation involving U.S. PEM fellows and Pakistani EM residents was an effective approach in assessing various aspects of intercultural education, such as language barriers, technical challenges, and religious considerations.

Abstract
BACKGROUND Endometriosis is a chronic, benign, and oestrogen-dependent condition and about 10-15% of all women of reproductive age are affected by endometriosis worldwide. It is not curable and pain is one of the most common symptoms of endometriosis and leads to low quality of life in affected women. To our knowledge, in German-speaking countries, no studies with qualitative methods approaches are available concerning women who suffer from pain caused by endometriosis and possible associated coping strategies. Our study aims to familiarise ourselves with the individual pain experience of selected women who suffer from endometriosis in Austria and their coping strategies. METHODS A qualitative study design was based on problem-centred interviews for data collection and qualitative content analysis for data analysis. The research participants were women aged between 18 and 55 diagnosed with endometriosis and living in Austria. The interview period was from 27 February to 26 March 2019 and interviews lasted between 50 and 75 min. RESULTS Eight categories were formulated, of which category 3 (thoughts and feelings regarding endometriosis and pain - 'why?'), category 5 (effects and changes caused by endometriosis and pain - 'quality of life'), category 7 (taboos - 'don`t talk about it'), and category 8 (talking about it - 'contact with others in the same position') were relevant for this article. The remaining four categories [1-4] have already been published elsewhere. CONCLUSION Our data show that the social environment plays a fundamental role in coping strategies concerning pain caused by endometriosis. Women in our study reported that exchange with peers offers support. This opens a door for information events, patient organizations like support groups, and the inclusion of these in the supporting system. Involving occupational medicine and workplace health promotion departments in companies should be further goals to support affected women.

Abstract
We present a rare case of humeral fracture dislocation with intrathoracic humeral head fragment. A 74-year old female was transferred to a major trauma facility after falling on her arm while gardening. An intrathoracic humeral head fragment was diagnosed after initial imaging. In correspondence with the department of thoracic surgery, the decision was made to remove the intrathoracic fragment thoracoscopically and succeed with a reverse total shoulder arthroplasty.

Abstract
Abstract: The topics of endometriosis and pain imply far-reaching problems for women’s health. Using a qualitative research approach, this paper addresses the subjective experience and effects of pain, the methods for dealing with these issues, and the needs of affected women in Austria. Data were collected by problem-focused interviews conducted with ten women suffering from endometriosis, which were later transcribed and subjected to qualitative content analysis. Findings are therefore described using content-related categories. Results show that negative thoughts and feelings like fear, despair, and anger are associated with endometriosis and pain. Moreover, predominantly negative impacts and changes are found in various areas of life, such as the well-being and psyche of those affected, their attitude towards life in general, partnerships, social life, leisure time and work-life balance. In dealing with endometriosis and pain, both Western biomedicine and complementary medicine treatments are used. Support from one’s inner circle of friends and exchange and interaction with others affected by the disease are seen to be invaluable. Attending physicians as well as patients themselves and their private, social, and working environment should encourage open communication about endometriosis and the related pain.

Abstract
Competency-based medical education (CBME) curricula are becoming increasingly common in graduate medical education. Put simply, CBME is focused on educational outcomes, is independent of methods and time, and is composed of achievable competencies.1 In spite of widespread uptake, there remains much to learn about implementing CBME at the program level. Leveraging the collective experience of program leaders at Queen's University, where CBME simultaneously launched across 29 specialty programs in 2017, this paper leverages change management theory to provide a short summary of how program leaders can navigate the successful preparation, launch, and initial implementation of CBME within their residency programs.

Abstract
Candida vaginitis is a frequent clinical diagnosis with up to 8% of women experiencing recurrent vulvovaginal candidiasis (RVVC) globally. RVVC is characterized by at least three episodes per year. Most patients with RVVC lack known risk factors, suggesting a role for genetic risk factors in this condition. Through integration of genomic approaches and immunological studies in two independent cohorts of patients with RVVC and healthy individuals, we identified genes and cellular processes that contribute to the pathogenesis of RVVC, including cellular morphogenesis and metabolism, and cellular adhesion. We further identified SIGLEC15, a lectin expressed by various immune cells that binds sialic acid-containing structures, as a candidate gene involved in RVVC susceptibility. Candida stimulation induced SIGLEC15 expression in human peripheral blood mononuclear cells (PBMCs) and a polymorphism in the SIGLEC15 gene that was associated with RVVC in the patient cohorts led to an altered cytokine profile after PBMC stimulation. The same polymorphism led to an increase in IL1B and NLRP3 expression after Candida stimulation in HeLa cells in vitro. Last, Siglec15 expression was induced by Candida at the vaginal surface of mice, where in vivo silencing of Siglec15 led to an increase in the fungal burden. Siglec15 silencing was additionally accompanied by an increase in polymorphonuclear leukocytes during the course of infection. Identification of these pathways and cellular processes contributes to a better understanding of RVVC and may open new therapeutic avenues.

Abstract
The aim of this study was to detect selection signatures considering cows from the German Holstein (GH) and the local dual-purpose black and white (DSN) population, as well as from generated sub-populations. The 4654 GH and 261 DSN cows were genotyped with the BovineSNP50 Genotyping BeadChip. The geographical herd location was used as an environmental descriptor to create the East-DSN and West-DSN sub-populations. In addition, two further sub-populations of GH cows were generated, using the extreme values for solutions of residual effects of cows for the claw disorder dermatitis digitalis. These groups represented the most susceptible and most resistant cows. We used cross-population extended haplotype homozygosity methodology (XP-EHH) to identify the most recent selection signatures. Furthermore, we calculated Wright's fixation index (FST ). Chromosomal segments for the top 0.1 percentile of negative or positive XP-EHH scores were studied in detail. For gene annotations, we used the Ensembl database and we considered a window of 250 kbp downstream and upstream of each core SNP corresponding to peaks of XP-EHH. In addition, functional interactions among potential candidate genes were inferred via gene network analyses. The most outstanding XP-EHH score was on chromosome 12 (at 77.34 Mb) for DSN and on chromosome 20 (at 36.29-38.42 Mb) for GH. Selection signature locations harbored QTL for several economically important milk and meat quality traits, reflecting the different breeding goals for GH and DSN. The average FST value between GH and DSN was quite low (0.068), indicating shared founders. For group stratifications according to cow health, several identified potential candidate genes influence disease resistance, especially to dermatitis digitalis.

Abstract
BACKGROUND The surgical management of complex humeral head fractures has adapted dynamically over the course of the last decade. The primary use of reverse shoulder arthroplasty in elderly patients has gained in relevance due to promising short and middle-term results. Long-term results, however, are still pending. The appliance of anatomical hemiarthroplasty, on the other hand, has lost in significance in favour of osteosynthesis and reverse shoulder arthroplasty. INDICATIONS This review article follows the question as to under which circumstances primary fracture arthroplasty reflects an alternative or even a preference to joint-preserving osteosynthesis in the treatment of complex proximal humeral fractures. It also specifies spectrums of indications for anatomical hemiarthroplasty and reverse shoulder arthroplasty.

Abstract
Background Congenital hypothyroidism (CH) has an incidence of approximately 1:3000, but only 15% have mutations in the thyroid hormone synthesis pathways. Genetic analysis allows for the precise diagnosis. Case presentation A 3-week old girl presented with a large goiter, serum TSH > 100 mIU/L (reference range: 0.7–5.9 mIU/L); free T4 < 3.2 pmol/L (reference range: 8.7–16 pmol/L); thyroglobulin (TG) 101 μg/L. Thyroid Tc-99 m scan showed increased radiotracer uptake. One brother had CH and both affected siblings have been clinically and biochemically euthyroid on levothyroxine replacement. Another sibling had normal thyroid function. Both Sudanese parents reported non-consanguinity. Peripheral blood DNA from the proposita was subjected to whole exome sequencing (WES). WES identified a novel homozygous missense mutation of the TG gene: c.7021G > A, p.Gly2322Ser, which was subsequently confirmed by Sanger sequencing and present in one allele of both parents. DNA samples from 354 alleles in four Sudanese ethnic groups (Nilotes, Darfurians, Nuba, and Halfawien) failed to demonstrate the presence of the mutant allele. Haplotyping showed a 1.71 centiMorgans stretch of homozygosity in the TG locus suggesting that this mutation occurred identical by descent and the possibility of common ancestry of the parents. The mutation is located in the cholinesterase-like (ChEL) domain of TG. Conclusions A novel rare missense mutation in the TG gene was identified. The ChEL domain is critical for protein folding and patients with CH due to misfolded TG may present without low serum TG despite the TG gene mutations.

Abstract
OBJECTIVE Stabilization of the humerus with preservation or restoration of the shoulder function. INDICATIONS Always in the presence of a loose prosthesis. It may become necessary in conditions of poor bone stock and if osteosynthesis is not possible. CONTRAINDICATIONS Noncompliant patients due to alcohol or drugs. Local infections. SURGICAL TECHNIQUE The loose implant is removed using an extended anterior deltopectoral approach. After exploration of the fracture and extended soft tissue release, the glenoidal components are implanted with visualization and protection of the axillary nerve. A long stemmed implant is typically needed on the humeral side. It is anchored in the distal fragment over a length of about 6 cm. Soft tissue tension is crucial, especially with reverse shoulder arthroplasty. POSTOPERATIVE MANAGEMENT Postoperatively, the affected limb is immobilized for 6 weeks on a 15° shoulder abduction pillow with active assisted movement therapy up to the horizontal plane. This is followed by gradual pain-adapted increases of movement, muscle coordination, and strength. RESULTS In 17 patients with periprosthetic fractures of the humerus surgically treated in our institution, 4 underwent revision arthroplasty because of a loose prosthesis. No intra- or postoperative complications were observed. All fractures healed except one.

Abstract
Background and Aims: Mild traumatic brain injury is a common presentation to Emergency Departments. Early identification of patients with cognitive deficits and provision of discharge advice are important. The Abbreviated Westmead Post-traumatic Amnesia Scale provides an early and efficient assessment of post-traumatic amnesia for patients with mild traumatic brain injuries, compared with the previously used assessment, the Modified Oxford Post-traumatic Scale. Material and Methods: This retrospective cohort study reviewed 270 patients with mild traumatic brain injury assessed for post-traumatic amnesia over a 2-year period between February 2011 and February 2013. It identified those assessed with Abbreviated Westmead Post-traumatic Amnesia Scale versus Modified Oxford Post-traumatic Scale, the outcomes of these post-traumatic amnesia assessments, the hospital length of stay for patients, and their readmission rates. Results: The Abbreviated Westmead Post-traumatic Amnesia Scale was used in 91% of patient cases (and the Modified Oxford Post-traumatic Scale in 7%), and of those assessed with the Abbreviated Westmead Post-traumatic Amnesia Scale, 94% cleared post-traumatic amnesia testing within 4 h. Of those assessed with the Abbreviated Westmead Post-traumatic Amnesia Scale, 56% had a shorter length of stay than had they been assessed with the Modified Oxford Post-traumatic Scale, resulting in 295 bed-days saved. Verbal and written discharge advice was provided to those assessed for post-traumatic amnesia to assist their recovery. In all, 1% of patients were readmitted for monitoring of mild post-concussion symptoms. Conclusion: The Abbreviated Westmead Post-traumatic Amnesia Scale provides an effective and timely assessment of post-traumatic amnesia for patients presenting to the Emergency Department with mild traumatic brain injury compared with the previously used assessment tool. It helps identify patients with cognitive impairment and the need for admission and further investigation, resulting in appropriate access to care. It also results in a decreased length of stay and decreased hospital admissions, with subsequent cost savings to the hospital.

Abstract
This prospective pilot study evaluated whether low preoperative cerebral tissue oxygen saturation is associated with unfavourable outcomes after major elective non-cardiac surgery. Eighty-one patients over 60 years of age, American Society of Anesthesiologists physical status 3 or 4, were recruited. Resting cerebral tissue oxygen saturation was recorded on room air, and after oxygen supplementation, using cerebral oximetry. The primary outcome was 30-day major adverse event of combined mortality or severe morbidity, and the secondary outcome was 30-day new disability. Eleven patients (13.6%) suffered a major adverse event, and 28 patients (34.6%) experienced new disability. Room air cerebral tissue oxygen saturation was significantly different between patients who had a major adverse event, 67% (95% confidence interval [CI] 65–70) versus unaffected, 71% (95% CI 70–72; P=0.04). No statistical difference was found between patients for new disability (range 70%– 74%; P=0.73). Room air cerebral tissue oxygen saturation was significantly associated with major adverse events (odds ratio 1.36 (95% CI 1.03–1.79), P=0.03). Saturation levels ≤68% carried a positive likelihood ratio of 2.2 for death or severe morbidity, P=0.04. A definitive trial is required to confirm if cerebral oximetry can be used to stratify the cardiovascular risk of patients presenting for non-cardiac surgery.

Abstract
Vaginal infections with Candida spp. frequently occur in women of childbearing age. A small proportion of these women experience recurrent vulvovaginal candidosis (RVVC), which is characterized by at least three episodes of infection in one year. In addition to known risk factors such as antibiotics, diabetes, or pregnancy, host genetic variation and inflammatory pathways such as the IL-1/Th17 axis have been reported to play a substantial role in the pathogenesis of RVVC. In this study, we assessed a variable number tandem repeat (VNTR) polymorphism in the NLRP3 gene that encodes a component of the inflammasome, processing the proinflammatory cytokines IL-1β and IL-18. A total of 270 RVVC patients and 583 healthy controls were analyzed, and increased diseases susceptibility was associated with the presence of the 12/9 genotype. Furthermore, functional studies demonstrate that IL-1β production at the vaginal surface is higher in RVVC patients bearing the 12/9 genotype compared to controls, whereas IL-1Ra levels were decreased and IL-18 levels remained unchanged. These findings suggest that IL-1β-mediated hyperinflammation conveyed by the NLRP3 gene plays a causal role in the pathogenesis of RVVC and may identify this pathway as a potential therapeutic target in the disease.

Abstract
Although non-unions in the upper limb are rare different treatment options of this challenging situation are still affected with up to 20% of failure rate due to current literature. Risk factors for delayed and non-union of fractures are mainly the size of the fracture gap and bone loss of open fractures or in primary surgery followed by other relevant internal and external factors. In the upper limb non-unions of long bones are described with up to 30% after operative intervention. Especially in the upper limb range of motion is limited in non-union cases and disables adjacent joints like the shoulder, elbow and wrist hence reducing the total activity level of affected patients. Beside careful investigation of the causes leading to the non-union a comprehensive treatment plan should be defined to achieve successful results. Treatment can be non-operative in several, selected cases, but in the majority of cases revision surgery is necessary to achieve osseous healing. Our own experience showed that non-union in the upper limb are rare and account for only 1.7% of all surgical managed upper limb fractures. Non-union of upper limb fractures occur most frequently in clavicle fractures followed by humeral fractures. Atrophic non-union is the most frequent reason for osseous non-union (57%) and osseous healing after revision surgery in non-unions is completed after a mean of 6.45 months. This article will give a brief overview of the genesis, clinical evaluation, treatment options and recommendations in upper limb non-unions according to the current literature. Key words: fracture, upper-limb, non-union, osteosynthesis, cancellous bone-graft.

Abstract
BACKGROUND Allergic bronchopulmonary aspergillosis (ABPA) is characterised by an exaggerated Th2 response to Aspergillus fumigatus, but the immunological pathways responsible for this effect are unknown. OBJECTIVE The aim of this study was to decipher the pattern recognition receptors (PRRs) and cytokines involved in the Aspergillus-specific Th2 response and to study Aspergillus-induced responses in healthy controls and ABPA patients. METHODS Peripheral blood mononuclear cells (PBMCs) were stimulated with heat-killed Aspergillus conidia, various other pathogens, or PRR ligands. PRRs and cytokine pathways were blocked with PRR-blocking reagents, anti-TNF (Etanercept or Adalimumab), IL-1Ra (Anakinra) or IFNγ (IFN-gamma). ELISA and FACS were used to analyse cytokine responses. RESULTS Aspergillus was the only pathogen that stimulated the Th2 cytokines IL-5 and IL-13, while Gram-negative bacteria, Gram-positive bacteria, Candida albicans, chitin, β-glucan or Toll-like receptor (TLR) ligands did not. Depletion of CD4(+) cells abolished IL-13 production. Blocking complement receptor 3 (CR3) significantly reduced IL-5 and IL-13, while blocking TLR2, TLR4 or dectin-1 had no effect. ABPA patients displayed increased Aspergillus-induced IL-5 and IL-13 and decreased IFNγ production compared with healthy controls. All biological agents tested showed the capability to inhibit Th2 responses, but also decreased Aspergillus-induced IFNγ. CONCLUSIONS AND CLINICAL RELEVANCE Aspergillus conidia are unique in triggering Th2 responses in human PBMCs, through a CR3-dependent pathway. ABPA patients display a significantly increased Aspergillus-induced Th2/Th1 ratio that can be modulated by biologicals. These data provide a rationale to explore IFNγ therapy in ABPA as a corticosteroid-sparing treatment option, by dampening Th2 responses and supplementing the IFNγ deficiency at the same time.

Abstract
The cervical spine of breakdancers is at great risk due to reversed body loading during headspin manoeuvers. This study focused on the cervical biomechanics of breakdancers and a correlation with neck pain. A standardized interview and biomechanical testing of the cervical spine of 25 participants with "headspin" ability ages 16-34 years and an age-matched cohort of 25 participants without any cervical spine problems was conducted. Neck pain history, Neck Disability Index (NDI), cervical range of motion (CROM) and cervical torque were recorded. The "headspin" group reported significantly better subjective fitness, more cervical complaints, higher pain intensity, a longer history of neck pain and a worse NDI compared to the "normal" collective. The "headspin" group showed a 2-2.5 times higher rate of neck pain than the normal population, with increased cervical flexion (p<0.05) and increased cervical torque in all planes (p<0.001). The CROM showed a negative moderate to strong correlation with NDI, pain intensity and history of neck pain. Sports medicine practitioners should be aware of headspin maneuver accidents that pose the risk of fractures, dislocations and spinal cord injuries of breakdancers.

Abstract
Traumatic injuries of the sternoclavicular joint occur rarely and are mainly caused by an indirect trauma mechanism with high kinetic energy. Anterior dislocation is much more common than posterior dislocation, which may be associated with life-threatening injuries. The CT scan is the diagnostic tool of choice for accurate assessment of the injury and coexisting pathologies. The primary goal in anterior and posterior dislocations is an early closed reduction. In cases of redislocation after closed reduction of an anterior dislocation we recommend primary joint reconstruction on the basis of an individual therapeutic concept. Posterior dislocations often cannot be reduced by closed means. Then open reconstruction and stabilization are performed. Chronic instabilities should only be addressed surgically in cases of persistent pain and/or functional deficit. Resection of the medial clavicula represents an effective treatment option in post-traumatic sternoclavicular joint arthritis provided that the costoclavicular ligaments are intact or will be reconstructed during surgery. Physeal injuries of the medial clavicle can occur until an approximate age of 25. Closed reduction of dislocated physeal injuries is attempted. After reposition non-operative treatment in general leads to a good functional outcome. Posteriorly dislocated physeal injuries often cannot be reduced by closed means. In these cases good function can be expected after open stabilization.

Abstract
Fractures of the humeral shaft are less frequent than those of the proximal humerus. The formerly recommended treatment of humeral shaft fractures was conservative according to Böhler. This still remains an adequate concept of treatment but according to a change in the technical possibilities and the demands of patients and physicians on fast restoration of function and low pain, there is a trend towards surgical stabilization of humeral shaft fractures. The implant of choice is discussed controversially and consists of various types of nails versus plating. The technique of nailing is antegrade or retrograde and depends on the localization of the fracture. In our opinion good indications for plating are combined fractures of the proximal humerus and the shaft as well as very distal humeral shaft fractures. A primary lesion of the radial nerve is no imperative indication for exploration and different studies have shown the same results for exploration after 2 or 3 months if there is no spontaneous remission.

Abstract
We investigated two commercially available probes for measurement of the partial pressure of brain tissue oxygen (PbrO2) and calculation of the index of brain tissue oxygen pressure reactivity (ORx) in 7 patients after aneurysmal subarachnoid hemorrhage (SAH). Simultaneous monitoring of PbrO2 using the Licox(®) probe and the multiparameter Raumedic probe (Neurovent PTO(®)), measuring PbrO2, intracranial pressure (ICP) and brain temperature (Neurovent PTO) was performed for a median of 9 days (range 7-17 days). Both probes provided stable monitoring throughout the desired period. Mean PbrO2 from Licox and Neurovent PTO was 16.1 ± 9.0 mmHg and 17.5 ± 11.9 mmHg respectively. Mean ORx was 0.35 ± 0.44 and 0.31 ± 0.43 respectively. There was a difference in the measurement of PbrO2 of -2.73 ± 10.1 mmHg (Licox - Raumedic). The difference in the two values for the calculated ORx was far smaller (0.03 ± 0.31; Licox - Raumedic) and the correlation coefficient higher than for both values of PbrO2 (0.76 for ORx vs. 0.56 for PbrO2). The calculation of the autoregulation parameter ORx seemed more independent of the measurement process than the measurement of PbrO2 itself and signifies the potential clinical importance of this parameter.

Abstract
For real-time optoacoustic (OA) imaging of the human body, a linear array transducer and reflection mode optical irradiation is usually preferred. Such a setup, however, results in significant image background, which prevents imaging structures at the ultimate depth determined by the light distribution and the signal noise level. Therefore, we previously proposed a method for image background reduction, based on displacement-compensated averaging (DCA) of image series obtained when the tissue sample under investigation is gradually deformed. OA signals and background signals are differently affected by the deformation and can thus be distinguished. The proposed method is now experimentally applied to image artificial tumours embedded inside breast phantoms. OA images are acquired alternately with pulse-echo images using a combined OA/echo-ultrasound device. Tissue deformation is accessed via speckle tracking in pulse echo images, and used to compensate in the OA images for the local tissue displacement. In that way, OA sources are highly correlated between subsequent images, while background is decorrelated and can therefore be reduced by averaging. We show that image contrast in breast phantoms is strongly improved and detectability of embedded tumours significantly increased, using the DCA method.

Abstract
We investigated vapor bubbles generated upon irradiation of gold nanoparticles with nanosecond laser pulses. Bubble formation was studied both with optical and acoustic means on supported single gold nanoparticles and single nanoparticles in suspension. Formation thresholds determined at different wavelengths indicate a bubble formation efficiency increasing with the irradiation wavelength. Vapor bubble generation in Bac-1 cells containing accumulations of the same particles was also investigated at different wavelengths. Similarly, they showed an increasing cell damage efficiency for longer wavelengths. Vapor bubbles generated by single laser pulses were about half the cell size when inducing acute damage.

Abstract
BACKGROUND The Health of the Nation Outcome Scales (HoNOS) were developed to assess the severity of a mental illness. They are used as outcome measures in different countries, and are meanwhile translated from the original English version into many languages, among others into German (HoNOS-D). We conducted a study in order to estimate the concurrent validity and sensitivity to change using clinical parameters as ICD-10 diagnoses, as well as the Clinical Global Impression Scale (CGI), and the Association for Methodology and Documentation in Psychiatry (AMDP) psychopathology scale, a frequently used psychopathological rating system, in a representative clinical sample. SAMPLING AND METHODS Data on the three instruments (CGI, AMDP, HoNOS-D) were collected at admission and discharge of 100 psychiatric inpatients using a representative clinical sample. Experienced clinicians completed the CGI, AMDP and HoNOS-D. Descriptive and comparative data analyses were performed. We estimated the concurrent validity by calculating correlations between the HoNOS and other scales. Secondly, we examined the differences between HoNOS scores related to diagnoses and demographic parameters. Thirdly we calculated change criteria and outcome effect size for the HoNOS. RESULTS Even in a small clinical sample (n = 100), the HoNOS-D items are highly correlated with the corresponding AMDP syndromes (p < 0.003). The HoNOS-D score is associated with the CGI score (p < 0.01). Correlations of HoNOS symptoms, behavior and impairment items with AMDP syndromes as well as differences in diagnoses were appropriate and comprehensible as regards clinical content, and change on the HoNOS total score is statistically significant (t = 6.57, d.f. = 89, p < 0.0001). CONCLUSION This study is the first to investigate the concurrent validity of HoNOS-D concerning psychopathology using the AMDP rating system in a clinical sample of patients with mental disorders in an inpatient setting. HoNOS-D can be recommended for routinely screening outcomes in inpatient psychiatric settings. Our analysis showed that HoNOS-D covers psychopathology corresponding to the AMDP rating system. A limitation of the study is that the study sample comprised only an inpatient population; there may well be differences compared to an outpatient sample.

Humeral shaft fractures account for about 1-3% of all fractures. These fractures are regarded as the domain of non-surgical management. This is certainly still the contemporary view but there is an obvious trend towards surgical stabilization. Surgical treatment of humeral shaft fractures has nonetheless been greatly facilitated by the development of new implants. In particular, a new generation of nails that general permit immediate mobilization have become available for improved management of longitudinal and multi-segmental fractures. Retrograde and antegrade nails have advantages and disadvantages and selection procedure is often based on the distal or proximal location of the fracture. Plates also offer an alternative for certain indications and have advantages at the proximal and distal shaft in particular. If there is primary lesion of the radial nerve, exploration is not very advisable, but in the absence of remission exploration can be conducted after several months with the same degree of success. Since the published literature offers no comparative studies with a high level of evidence, our statement can only be regarded as an up-to-date recommendation in the hope that future prospective randomized studies will address this issue.

Abstract
OBJECTIVE To define prognostic factors in chronically symptomatic patients with calcific tendinitis of the shoulder. METHODS We evaluated 420 patients (488 shoulders) in the context of a prospective cohort study. Epidemiologic data were assessed. The radiographic and sonographic appearance of the calcific deposits was classified. The mean period of nonoperative therapy was 4.4 years (range 0.5-13.7 years). After referral to our institution, standardized nonoperative therapy was continued for a minimum of 3 months. Failure of nonoperative therapy was defined as the persistence of symptomatic calcific tendinitis of the shoulder after a minimum of 6 months. Prognostic factors (determined at P < 0.05 by chi-square test) were analyzed by logistic regression. RESULTS Of the 420 patients, 269 (64%) were women, 151 (36%) were men. The mean age of the patients was 51.3 years (range 28-84 years). Occurrence of calcific tendinitis of the shoulder was unilateral in 84% and bilateral in 16%. Gärtner type I calcific deposits were found in 37%, type II in 32%, and type III in 31%. Failure of nonoperative therapy was observed in 114 patients (27%). Negative prognostic factors were bilateral occurrence of calcific tendinitis of the shoulder, localization to the anterior portion of the acromion, medial (subacromial) extension, and high volume of the calcific deposit. Positive prognostic factors were a Gärtner type III deposit and a lack of sonographic sound extinction of the calcific deposit. CONCLUSION Our findings demonstrate the existence of prognostic factors in the nonoperative treatment of chronic symptomatic calcific tendinitis of the shoulder. Guidelines for optimal treatment can be implemented according to these factors to avoid a long-term symptomatic disease course.
