CONCLUSIONS Out-of-school AGYW had differential vulnerability to HIV. Interventions should focus on reaching AGYW in the high HIV vulnerability profiles.OBJECTIVES This study presents findings from piloting an adapted evidence-based intervention, Stepping Stones and Creating Futures, to change street-connected young people's HIV knowledge, condom-use self-efficacy, and sexual practices. METHODS Eighty street-connected young people participated in a pre- and post-test mixed methods design in Eldoret, Kenya. The primary outcome of interest was HIV knowledge. Secondary outcomes included condom-use self-efficacy and sexual practices. Multiple linear regression models for change scores with adjustment for socio-demographic variables were fitted. Qualitative and quantitative findings are presented together, where integration confirms, expands on, or uncovers discordant findings. RESULTS Participants had a significant increase in HIV knowledge from pre- to post-intervention. The median HIV knowledge score pre-intervention was 11 (IQR 8-13) and post-intervention 14 (IQR 12-16). Attendance was significantly associated with HIV knowledge change scores. Qualitatively participants reported increased HIV and condom-use knowledge and improved condom-use self-efficacy and health-seeking practices. CONCLUSIONS Our findings support the potential for further testing with a rigorous study design to investigate how best to tailor the intervention, particularly by gender, and increase the overall effectiveness of the program.A 33-year-old woman in a seriously ill state presented with hepatic abscesses. The proof of epitheloid-like reactions by biopsy and further serological analysis led to the final diagnosis of tularemia, which represents a rare disease in Germany. Thereafter targeted antibiotic therapy was successfully initiated. The contribution of simultaneously diagnosed celiac disease to the unusual manifestation of tularemia in the liver, remains uncertain.Tumours can escape the immune system by expressing programmed death-ligand-1 (PD-L1), which allows them to bind to PD-1 on T-cells and avoid recognition by the immune system. Regulatory T-cells (Tregs), indoleamine 2,3-dioxygenase (IDO) and tryptophan 2,3-dioxygenase (TDO) also play a role in immune suppression. Knowledge about the interaction of neuroendocrine tumours (NETs) with their immune microenvironment and the role of immunotherapy in patients with NET is scarce. Here, we investigated the immune microenvironment of serotonin-producing (SP) and non-serotonin-producing NETs (NSP-NETs). Tumours of 33 patients with SP-NET and 18 patients with NSP-NET were studied. Immunohistochemical analyses were performed for PD-L1, T-cells, IDO, TDO, mismatch repair proteins (MMRp) and activated fibroblasts. PD-L1 expression was seen in less then  1% of tumour and T-cells. T-cells were present in 33% of NETs, varying between 1 and 10% T-cells per high power field. IDO was expressed in tumour cells in 55% of SP-NETs and 22% of NSP-NETs (p = 0.039). TDO was expressed in stromal cells in 64% of SP-NETs and 13% of NSP-NETs (p = 0.001). No tumours had loss of MMRp. TDO-expressing stromal cells also strongly expressed α-SMA and were identified as cancer-associated fibroblasts (CAFs). find more Factors that are associated with a response to checkpoint inhibitor treatment were absent or only present to a limited extent in the tumour microenvironment of NETs. The expression of IDO and TDO in a substantial part of NETs and the presence of CAFs suggest two mechanisms that could be responsible for the cold immune microenvironment, which should be explored to enhance anti-tumour immunity and clinical responses.Dermatological and venereological expertise is indispensable for the medical care of our soldiers at home and during military missions and represents a major competence in military medicine. Therefore, in the new structure of the combined German Forces medical services, dermatological clinics have been set up at all Bundeswehr hospitals, which, as academic teaching hospitals, are regionally involved in the medical care of the civilian population. In addition to general dermatological and dermatosurgical care, wound treatment and tropical dermatology represent military medicine-related priorities. Dermatological clinics are maintained in an interdisciplinary network at the Bundeswehr hospitals in Berlin, Hamburg, Koblenz, Ulm, and Westerstede. Outpatient dermatological treatment facilities complete the medical care at numerous locations where troops are based.PURPOSE There is no study exploring the positional relationship between the external acoustic meatus (EAM) and the sigmoid sinus (SS) in detail. The present study aimed to characterize the relationship using contrast magnetic resonance imaging (MRI). METHODS In total, 85 patients with an intact EAM, SS, and surrounding structures underwent thin-sliced, contrast MRI. Imaging data were transferred to a workstation for analysis. RESULTS In all patients, the EAM and SS were well depicted on both the sagittal and axial images. The relationships and distances between the EAM and SS, in addition to the shape of cross sections of the EAM, were highly variable with left-right asymmetry. The positional relationships between the EAM and the anterior edge of the SS were classified into superior, intervening, and inferior types. The intervening type was the most predominant, accounting for 85%. The shortest distance between the posterior wall of the EAM and the anterior margin of the SS was 12.3 ± 3.9 mm on the right side and 13.0 ± 2.9 mm on the left. In three women, the distance was less than 5 mm on the right side. CONCLUSIONS The positional relationship between the EAM and SS is highly variable and inconsistent. These structures may be adjacent, especially on the right side, and presurgical contrast MRI should be included when planning surgeries around the EAM.Inherited or acquired mutations can lead to pathological outcomes. However, in a process defined as synthetic rescue, phenotypic outcome created by primary mutation is alleviated by suppressor mutations. An exhaustive characterization of these mutations in humans is extremely valuable to better comprehend why patients carrying the same detrimental mutation exhibit different pathological outcomes or different responses to treatment. Here, we first review all known suppressor mutations' mechanisms characterized by genetic screens on model species like yeast or flies. However, human suppressor mutations are scarce, despite some being discovered based on orthologue genes. Because of recent advances in high-throughput screening, developing an inventory of human suppressor mutations for pathological processes seems achievable. In addition, we review several screening methods for suppressor mutations in cultured human cells through knock-out, knock-down or random mutagenesis screens on large scale. We provide examples of studies published over the past years that opened new therapeutic avenues, particularly in oncology.OBJECTIVE Although radiofrequency ablation is well validated for treatment of osteoid osteoma, newer technologies, namely cryoablation, have been less thoroughly studied. The purpose is to perform a systematic review and pooled analysis of percutaneous ablation technologies for treatment of osteoid osteoma with subset analysis of intra-articular and spinal tumors. MATERIAL AND METHODS A total of 36 of 79 identified manuscripts met inclusion criteria, comprising 1863 ablations in 1798 patients. Inclusion criteria were (1) retrospective or prospective analysis of thermal ablation of osteoid osteomas in any location, (2) at least 6 months of clinical follow-up, (3) 10 or more patients, (4) patients not included in a second study included in this review, and (5) English language or English translation available. Success rate was defined as all ablations minus technical failures, clinical failures, and recurrences. Subset analysis of intra-articular and spinal tumors was performed. RESULTS Overall success rate was 91.9% (95% CI 91-93%). Technical failure, clinical failure, and recurrence rates were 0.3%, 2.1%, and 5.6% respectively. Complications were seen in 2.5% (95% CI 1.9-3.3%) patients. There was no significant difference when comparing radiofrequency ablation and cryoablation (p = 0.92). Success rates for intra-articular (radiofrequency ablation) and spinal tumors (radiofrequency and cryoablation) were 97% and 91.6% respectively. CONCLUSION Percutaneous ablation of osteoid osteomas was highly successful with low complication rates. Efficacy of radiofrequency ablation and cryoablation is similar, which is consequential because cryoablation is associated with decreased pain, predictable nerve regeneration, and theoretical immunotherapy benefits. Treatment of more challenging intra-articular and spinal lesions demonstrated similarly high success and low complication rates.Acute eosinophilic pneumonia (AEP) is a rare disease characteristically involving eosinophilic infiltration of lung parenchyma as well as fever, dyspnea, and coughing. A differentiation is made between primary and secondary AEP depending on the underlying etiology. Substances that most frequently cause secondary AEP are antibiotics, such as the lipopeptide daptomycin. This is a case report about a 69-year-old female patient who underwent antibiotic treatment with daptomycin for an infection of a knee prosthesis. During the treatment, signs of pneumonia developed and included the increased dependence on mechanical ventilation of the previously intubated patient, infiltrates on a chest X‑ray, fever, and an increase in serum inflammation markers. Proof of bacteria as an underlying pathogen was not possible. A thoracic computed tomography (CT) scan showed opacities that are commonly seen in interstitial lung disease. Termination of daptomycin treatment due to renal failure led to an improvement of pulmonary symptoms. Re-exposure to daptomycin resulted in a recurrence of the symptoms. The diagnostic criteria for AEP according to Uppal et al. include 1) current exposure to daptomycin, 2) dyspnea with increased oxygen requirements or necessity for mechanical ventilation, 3) new infiltrates on chest X‑ray or CT scan, 4) bronchoalveolar lavage with eosinophilia >25%, 5) improvement of clinical symptoms following daptomycin withdrawal, and 6) fever. With 5 out of the 6 criteria by Uppal et al. positive-an eosinophilia >25% being the only unmet criteria-an AEP induced by daptomycin was diagnosed. Withdrawal of daptomycin as well as high-dose cortisol bolus treatment led to a rapid recovery.BACKGROUND The first enhanced recovery after surgery (ERAS) guidelines for pancreatoduodenectomy (PD) were developed in 2012. The study aimed to assess compliance and outcomes of an ERAS protocol for PD, to study correlation between compliance and outcomes, and to identify risk factors for complications. METHODS Retrospective cohort analysis is based on a prospective database, including all consecutive patients undergoing elective PD within an ERAS program in four centers Lausanne University Hospital (Switzerland), Carolinas Medical Center (United States), Edouard Herriot Hospital (France), and University Medical Center Hamburg-Eppendorf (Germany). Patients' characteristics, postoperative outcome and ERAS compliance were assessed. Logistic regression analysis was performed to assess predictors of postoperative complications. RESULTS Between October 2012 and June 2017, 404 consecutive patients underwent PD. Median length of stay was 14 days with 11.3% readmission rate. Mean overall compliance was 62%, with pre-, intra- and postoperative compliance of 93%, 80% and 30%, respectively.
