RESUMO

A 58-year-old patient was admitted to the emergency department due to severe respiratory insufficiency. Anamnesis revealed that the patient had experienced increasing stress dyspnea for a few months. Upon imaging, an acute pulmonary embolism was excluded, but peribronchial and hilar soft tissue proliferation with compression of central parts of the pulmonary circulation was found. The patient had a history of silicosis. The histology report showed tumor-free lymph node particles with prominent anthracotic pigment and dust depositions without evidence of IgG4-associated disease. The patient was administered steroid therapy and underwent simultaneous stenting of the left interlobular pulmonary artery and the upper right pulmonary vein. As a result, a significant improvement in symptoms and physical performance was achieved. The diagnosis of inflammatory or, in particular, fibrosing mediastinal processes can be challenging and important clinical symptoms must be taken into account, especially if the pulmonary vasculature is involved. In such cases, the possibility of interventional procedures should be examined in addition to drug therapy options.

RESUMO

Metastatic fat necrosis due to inflammatory or neoplastic pancreatic diseases is rare. This phenomenon is attributed to systemic effects of pancreatic enzymes. Depending on the sites of fat necrosis, a number of different diseases may be mimicked, leading to incorrect diagnosis and therapies. Many case reports describe the phenomenon of skin, joint and bone manifestations of fat necrosis under the acronym PPP (pancreatic, panniculits, polyarthritis) syndrome. The management of "autodigestion" primarily consists of treating the underlying pancreatic disease.

RESUMO

T-cell prolymphocytic leukemia (T-PLL) is a poor-prognostic neoplasm. Differentiation stage and immune-effector functions of the underlying tumor cell are insufficiently characterized. Constitutive activation of the T-cell leukemia 1A (TCL1A) oncogene distinguishes the (pre)leukemic cell from regular postthymic T cells. We assessed activation-response patterns of the T-PLL lymphocyte and interrogated the modulatory impact by TCL1A. Immunophenotypic and gene expression profiles revealed a unique spectrum of memory-type differentiation of T-PLL with predominant central-memory stages and frequent noncanonical patterns. Virtually all T-PLL expressed a T-cell receptor (TCR) and/or CD28-coreceptor without overrepresentation of specific TCR clonotypes. The highly activated leukemic cells also revealed losses of negative-regulatory TCR coreceptors (eg, CTLA4). TCR stimulation of T-PLL cells evoked higher-than-normal cell-cycle transition and profiles of cytokine release that resembled those of normal memory T cells. More activated phenotypes and higher TCL1A correlated with inferior clinical outcomes. TCL1A was linked to the marked resistance of T-PLL to activation- and FAS-induced cell death. Enforced TCL1A enhanced phospho-activation of TCR kinases, second-messenger generation, and JAK/STAT or NFAT transcriptional responses. This reduced the input thresholds for IL-2 secretion in a sensitizer-like fashion. Mice of TCL1A-initiated protracted T-PLL development resembled such features. When equipped with epitope-defined TCRs or chimeric antigen receptors, these Lckpr-hTCL1Atg T cells gained a leukemogenic growth advantage in scenarios of receptor stimulation. Overall, we propose a model of T-PLL pathogenesis in which TCL1A enhances TCR signals and drives the accumulation of death-resistant memory-type cells that use amplified low-level stimulatory input, and whose loss of negative coregulators additionally maintains their activated state. Treatment rationales are provided by combined interception in TCR and survival signaling.

RESUMO

BACKGROUND: Ultrarare Marshall-Smith and Malan syndromes, caused by changes of the gene nuclear factor I X (NFIX), are characterised by intellectual disability (ID) and behavioural problems, although questions remain. Here, development and behaviour are studied and compared in a cross-sectional study, and results are presented with genetic findings. METHODS: Behavioural phenotypes are compared of eight individuals with Marshall-Smith syndrome (three male individuals) and seven with Malan syndrome (four male individuals). Long-term follow-up assessment of cognition and adaptive behaviour was possible in three individuals with Marshall-Smith syndrome. RESULTS: Marshall-Smith syndrome individuals have more severe ID, less adaptive behaviour, more impaired speech and less reciprocal interaction compared with individuals with Malan syndrome. Sensory processing difficulties occur in both syndromes. Follow-up measurement of cognition and adaptive behaviour in Marshall-Smith syndrome shows different individual learning curves over time. CONCLUSIONS: Results show significant between and within syndrome variability. Different NFIX variants underlie distinct clinical phenotypes leading to separate entities. Cognitive, adaptive and sensory impairments are common in both syndromes and increase the risk of challenging behaviour. This study highlights the value of considering behaviour within developmental and environmental context. To improve quality of life, adaptations to environment and treatment are suggested to create a better person-environment fit.

RESUMO

Eosinophilic granulocytes form peripheral effector cells controlled by Th2 lymphocytes, which cause local cell, tissue, and functional disorders of infiltrated organs via the release of cytotoxic basic proteins and oxygen radicals. Diseases associated with eosinophilia include systemic and organ-related forms. The lungs are involved in eosinophilic granulomatosis with polyangiitis (EGPA, formerly known as Churg-Strauss syndrome), acute and chronic eosinophilic pneumonia, as well as in an organ manifestation in hypereosinophilic syndrome and certain parasitic diseases. In particular, the lungs are frequently affected in vasculitis of small vessels, including EGPA, granulomatosis with polyangiitis (GPA), and microscopic polyangiitis (MPA). Among these, EGPA is the most frequent pulmonary eosinophil vasculitis representative. In addition, there are various overlap syndromes in which characteristic features of EGPA can be detected in the context of other anti-neutrophil cytoplasmic antibody (ANCA-)associated vasculitides. Occasionally, non-ANCA-associated pulmonary vasculitides occur with eosinophilia (e.g., Schönlein-Henoch purpura, Kawasaki disease, drug-induced hypersensitivity, and paraneoplastic syndrome). Herein, the pulmonary vasculitides accompanying eosinophilia are presented with respect to both the lung manifestations and pulmonary eosinophilia.

RESUMO

The potential of fish or fish oil as supplier for eicosapentaenoic acid (EPA, C20:5n3) and docosahexaenoic acid (DHA, C22:6n3) for reducing cardiovascular risk factors and supporting therapy of chronic inflammatory diseases, has been investigated intensively, but our knowledge about the physiological effects of the individual compounds EPA and DHA are limited. STUDY DESIGN: In this double-blind pilot study, thirty-eight patients with defined RA were allocated to consume foods enriched with microalgae oil from Schizochytrium sp. (2.1 g DHA/d) or sunflower oil (placebo) for 10 weeks (cross-over), maintaining the regular RA medication during the study. RESULTS: In contrast to placebo, the daily consumption of DHA led to a decline in the sum of tender and swollen joints (68/66) from 13.9 ± 7.4 to 9.9 ± 7.0 (p = 0.010), total DAS28 from 4.3 ± 1.0 to 3.9 ± 1.2 (p = 0.072), and ultrasound score (US-7) from 15.1 ± 9.5 to 12.4 ± 7.0 (p = 0.160). The consumption of placebo products caused an increase of the n-6 PUFA linoleic acid and arachidonic acid (AA) in erythrocyte lipids (EL, p < 0.05). The amount of DHA was doubled in EL of DHA-supplemented patients and the ratios of AA/EPA and AA/DHA dropped significantly. We speculate that the production of pro-inflammatory/non-resolving AA-derived eicosanoids might decrease in relation to anti-inflammatory/pro-resolving DHA- and EPA-derived lipid mediators. In fact, plasma concentrations of AA-derived thromboxane B2 and the capacity of blood to convert AA to the pro-inflammatory 5-lipoxygenase product 5-hydroxyeicosatetraenoic acid were significantly reduced, while levels of the DHA-derived maresin/resolvin precursors 14-/17-hydroxydocosahexaenoic acid significantly increased due to DHA supplementation. CONCLUSION: The study shows for the first time that supplemented microalgae DHA ameliorates disease activity in patients with RA along with a shift in the balance of AA- and DHA-derived lipid mediators towards an anti-inflammatory/pro-resolving state.

RESUMO

BACKGROUND: Partial nephrectomy is the treatment of choice for clinical stage 1 renal tumours. Open partial nephrectomy is the standard operative technique. The use of minimally-invasive strategies such as laparoscopic, robot-assisted partial nephrectomy or laparoendoscopic single site (LESS) partial nephrectomy has increased in recent years. PATIENTS/MATERIAL AND METHODS: In this retrospective study, patients undergoing laparoscopic partial nephrectomy between December 2008 and November 2013 were evaluated. All patients presented with renal lesions suspicious for malignancy. Operations were performed as conventional laparoscopic transperitoneal partial nephrectomies (cLPN) or LESS partial nephrectomies (LESS-PN) in SITUS technique (single incision transumbilical surgery). The aim of the study was to compare perioperative outcome parameters such as duration of surgery, time of ischaemia, complications, need for transfusion, conversion rates, changes in renal function and duration of hospital stay in both groups. RESULTS: A total of 85 laparoscopic partial nephrectomies were performed in this study (72 cLPN and 13 LESS-PN). The average tumour size was 2.68±1.47 cm (cLPN) vs. 2.46±1.11 cm (LESS-PN). The mean duration of surgery was 175.17±50.026 min (cLPN) and 185.77±35.991 min (LESS-PN). 45 (62.5%) operations (cLPN) vs. 10 (76.9%) (LESS-PN) were performed in zero-ischaemia technique. There were no significant differences in perioperative outcome parameters between both groups. Postoperative complication rates (Clavien-Dindo≥3) were 11.1% (cLPN) vs. 7.7% (LESS-PN). CONCLUSIONS: LESS partial nephrectomy in SITUS technique is an attractive alternative to conventional laparoscopic and open partial nephrectomy.

RESUMO

BACKGROUND: Sudden cardiac death (SCD) accounts for approximately 30 % in patients with pulmonary arterial hypertension (PAH). The exact circumference for SCD in this patient population is still unclear. Malignant cardiac arrhythmias are reported to be rarely present. There are no systematic data concerning long-term electrocardiographic (ECG) recording in patients with PAH. OBJECTIVES: We sought to investigate the rate of potentially relevant arrhythmias in patients with pulmonary hypertension (PH). METHODS: Consecutive patients without diagnosis of known cardiac arrhythmias followed in our outpatient clinic for PH were enrolled in the study. All patients underwent a 72-h Holter ECG. Clinical data, 6-min walk distance, laboratory values, and echocardiography were collected/performed. RESULTS: Ninety-two consecutive patients (New York Heart Association class (NYHA) III/IV: 65.2 %/5.4 %, PH Group 1: 35.9 %, Group 3: 10.9 %, Group 4: 28.3 %, Group 5: 2.2 %) were investigated. Relevant arrhythmias were newly detected in 17 patients: non-sustained ventricular tachycardia (n = 12), intermittent second-degree heart block (n = 1), intermittent third-degree heart block (n= 3), and atrial flutter (n = 1). Echocardiographic systolic pulmonary pressure and diameter of the right heart were elevated in patients with relevant arrhythmias. Right heart catheterization revealed higher pulmonary vascular resistance (672 vs. 542 dyn · s · cm(-5), p = 0.247) and lower cardiac index (2.46 vs. 2.82 l/min/m(2), p = 0.184). CONCLUSIONS: Ventricular tachycardias occur more often in PH patients than previously reported. However, the prognostic relevance of non-sustained ventricular tachycardias in this cohort remains unclear. As a large number of PH patients die from SCD, closer monitoring, e.g., using implantable event recorders, might be useful to identify patients at high risk.

RESUMO

Only described in the last 10 years, IgG4-related disease is a fibroinflammatory disorder characterized by tumorous lesions with dense lymphoplasmacytic infiltration by IgG4-positive plasma cells and often elevated concentration of serum IgG4. In this paper, we present a male patient with this disease involving the lymph nodes and possibly the joints and kidneys. Infiltration of lymph node tissue with IgG4-positive plasma cells was demonstrated. The general condition of the patient improved considerably by immunosuppressive therapy.

RESUMO

BACKGROUND AND PURPOSE: B-type natriuretric peptide (BNP) is a marker of cardiac dysfunction that is released from myocytes in response to ventricular wall stress. Previous studies suggested that BNP predicts stroke events in addition to classical risk factors. It was suggested that the BNP-associated risk results from coronary atherosclerosis or atrial fibrillation. METHODS: Three thousand six hundred and seventy five subjects from the population-based Heinz Nixdorf Recall study (45-75 years; 47.6% men) without previous stroke, coronary heart disease, myocardial infarcts, open cardiac valve surgery, pacemakers and defibrillators were followed up over 110.1 ± 23.1 months. Cox proportional hazards regressions were used to examine BNP as a stroke predictor in addition to vascular risk factors (age, gender, systolic blood pressure, low-density lipoprotein, high-density lipoprotein, diabetes, smoking), renal insufficiency, atrial fibrillation/known heart failure and coronary artery calcification. RESULTS: Eighty-nine incident strokes occurred (80 ischaemic, 9 hemorrhagic). Subjects suffering stroke had significantly higher BNP values at baseline than the remaining subjects [26.3 (Q1; Q3 = 12.9; 51.0) vs. 17.4 (9.4; 31.4); P < 0.001]. In a multivariable regression, log10 BNP was an independent stroke predictor [hazard ratio 1.96, 95% confidence interval (CI) 1.13-3.41; P = 0.017] in addition to age (1.24 per 5 years, CI 1.04-1.49; P = 0.016), systolic blood pressure (1.25 per 10 mmHg, CI 1.14-1.38; P < 0.001), smoking (2.05, CI 1.24-3.39; P = 0.005), atrial fibrillation/heart failure (2.25, CI 1.05-4.83; P = 0.037) and computed-tomography-based log10 (coronary artery calcification + 1) (1.47, CI 1.15-1.88; P = 0.002). Log10 BNP predicted stroke in men but not women, both in subjects ≤65 and >65 years. In subsequent analyses, BNP discriminated the incidence of cardioembolic stroke (P for trend = 0.001), but not stroke of macroangiopathic (P = 0.555), microangiopathic (P = 0.809) or unknown (P = 0.367) origin. CONCLUSIONS: BNP predicts presumable cardioembolic stroke independent of coronary calcification.

RESUMO

UNLABELLED: Fracture risk in type 1 diabetes (T1D) is supposed to be underestimated by bone mineral density (BMD). Individuals with T1D had more prevalent fractures in a cross-sectional study. Serum levels of pentosidine, an advanced glycation end product, and poor glycaemic control were associated with prevalent fractures independent of BMD. INTRODUCTION: Type 1 diabetes (T1D) is associated with increased fracture risk. Bone mineral density (BMD) underestimates the risk of fractures in some individuals. The accumulation of advanced glycation end products (AGEs) impairs bone matrix and reduces bone strength. METHODS: In a cross-sectional study, 128 men and premenopausal women with T1D were evaluated. We compared traditional risk factors for fractures, BMD, parameters of bone metabolism and AGEs in individuals with and without prevalent fractures. An independent association of serum AGE levels with prevalent fractures was investigated. RESULTS: Individuals with prevalent fractures exhibited a longer duration of T1D, higher HbA1c and more diabetic-related complications. BMD at the femoral neck (z-score -0.76 ± 0.94 vs. -0.23 ± 1.02; p = 0.031) and total hip (z-score -0.54 ± 0.93 vs. 0.11 ± 1.11; p = 0.017) was lower in those with prevalent fractures. Individuals with fractures had higher pentosidine levels (164.1 ± 53.6 vs. 133.2 ± 40.4; p = 0.002). The levels of N-ε-(carboxymethyl)-lysine (CML) and endogenous secretory receptor for AGEs (esRAGE) did not significantly differ. Multivariate logistic regression analysis adjusted for age, BMI, family history of fractures, smoking, vitamin D deficiency, BMD at lumbar spine, femoral neck and total hip identified pentosidine levels and HbA1c as independent factors associated with prevalent fractures (odds ratio 1.02, 95% CI 1.00-1.03/pmol/ml increase of pentosidine; p = 0.008 and odds ratio 1.93, 95% CI 1.16-3.20 per percentage increase of HbA1c; p = 0.011). CONCLUSIONS: The pentosidine levels but not BMD are independently associated with prevalent fractures. Impaired bone quality in T1D may result from increased AGE formation.

RESUMO

BACKGROUND: The association of depression and hospital length of stay (LOS) has rarely been examined in surgical patients outside of cardiovascular surgery. This study investigates whether clinically significant preoperative depression shows an independent association with LOS in patients from various surgical fields after adjusting for age, gender and important somatic factors. METHODS: A total of 2624 surgical patients were included in this prospective observational study. Data were collected before the preoperative anesthesiological examination within a computer-assisted psychosocial self-assessment including screening for depression (Center for Epidemiologic Studies Depression Scale, CES-D). Data on peri- and postoperative somatic parameters were obtained from the electronic patient management system of the hospital six months after the preoperative assessment. RESULTS: LOS of patients with clinically significant depression (N.=296; median: 5 days, interquartile range: 3-8 days) was longer than LOS of patients without depression (N.=2328; median: 4 days, interquartile range: 2-6 days) (P<0.001). A multivariate logistic regression model with the binary dependent variable 'above versus below or equal to the median LOS' revealed that the significant association between depression and LOS persisted (OR: 1.822 [95% CI 1.360-2.441], P<0.001) when simultaneously including the covariates age, gender, ASA classification, Charlson Comorbidity Index, surgical field and POSSUM operative severity rating. CONCLUSION: Data suggest that the association of depression and LOS is independent of the impact of age, gender, surgical field, preoperative physical health, severity of medical comorbidity and extent of surgical procedure. Integration of depression therapy into routine care of surgical patients might be an option to improve outcomes.

RESUMO

BACKGROUND: Recently, indirect videolaryngoscopes have become increasingly important devices in difficult airway management. The aim of the present study was to investigate laryngoscopic view and intubation success using the new C-MAC® D-Blade in comparison to the established GlideScope® videolaryngoscope and conventional direct laryngoscopy in a randomized controlled trial. METHODS: Ninety-six adult patients with expected difficult airways undergoing elective ear, nose and throat surgery (ENT) requiring general anesthesia were investigated. Repeated laryngoscopy was performed using a conventional direct Macintosh laryngoscope (DL), C-MAC D-Blade (DB) and GlideScope (GS) in a randomized sequence before patients were intubated with the last device used. RESULTS: Both videolaryngoscopes showed significantly better C/L (Cormack-Lehane) classes than DL. Insufficient laryngoscopic view, defined as C/L ≥ III, was experienced in 18 patients (19.2%) with DL, in two patients with GS (2.1%) and in none with DB (0%). Time to best achievable laryngoscopic view did not differ between devices. Intubation time was significantly longer with both videolaryngoscopes (Median [Range] DB: 18 [8-33] s, and GS: 19 [9-34] s) than with DL (11 [5-26] s). However, intubation success was 100% for both DB and GS, whereas four patients could not be intubated using conventional direct laryngoscopy. CONCLUSION: Compared to direct Macintosh laryngoscopy, both C-MAC® D-Blade and GlideScope® comparably resulted in an improved view of the glottic opening with successful tracheal intubation in all patients.

RESUMO

The transcription factor Evi1 has an outstanding role in the formation and transformation of hematopoietic cells. Its activation by chromosomal rearrangement induces a myelodysplastic syndrome with progression to acute myeloid leukemia of poor prognosis. Similarly, retroviral insertion-mediated upregulation confers a competitive advantage to transplanted hematopoietic cells, triggering clonal dominance or even leukemia. To study the molecular and functional response of primary murine hematopoietic progenitor cells to the activation of Evi1, we established an inducible lentiviral expression system. EVI1 had a biphasic effect with initial growth inhibition and retarded myeloid differentiation linked to enhanced survival of myeloblasts in long-term cultures. Gene expression microarray analysis revealed that within 24 h EVI1 upregulated 'stemness' genes characteristic for long-term hematopoietic stem cells (Aldh1a1, Abca1, Cdkn1b, Cdkn1c, Epcam, among others) but downregulated genes involved in DNA replication (Cyclins and their kinases, among others) and DNA repair (including Brca1, Brca2, Rad51). Cell cycle analysis demonstrated EVI1's anti-proliferative effect to be strictly dose-dependent with accumulation of cells in G0/G1, but preservation of a small fraction of long-term proliferating cells. Although confined to cultured cells, our study contributes to new hypotheses addressing the mechanisms and molecular targets involved in preleukemic clonal dominance or leukemic transformation by Evi1.

RESUMO

Eosinophilic granulomatosis with polyangiitis (EGPA) is a systemic small vessel vasculitis associated with asthma and eosinophilia. Optimal therapy for maintenance of remission is yet to be defined. We present a case-series of three patients with EGPA in whom IFN-α, an immunomodulatory cytokine induced remission, which was maintained even after discontinuation of the drug. In all patients (ages 60, 51, and 50 years), remission was associated with normalisation of eosinophil counts and IgE-levels. Moreover, the patients remained in remission for one to four years. Two patients did not need further immunosuppression, one patient required low dose maintenance therapy. Although reversible side effects occur, IFN-α-therapy induces long-term remission of EGPA even after discontinuation of treatment.

RESUMO

Background The increasing prevalence of severe aortic valve defects correlates with the increase of life expectancy. For decades, surgical aortic valve replacement (AVR), under the use of extracorporeal circulation, has been the gold standard for treatment of severe aortic valve diseases. In Germany ~12,000 patients receive isolated aortic valve surgery per year. For some time, percutaneous balloon valvuloplasty has been used as a palliative therapeutic option for very few patients. Currently, alternatives for the established surgical procedures such as transcatheter aortic valve implantation (TAVI) have become available, but there are only limited data from randomized studies or low-volume registries concerning long-time outcome. In Germany, the implementation of this new technology into hospital care increased rapidly in the past few years. Therefore, the German Aortic Valve Registry (GARY) was founded in July 2010 including all available therapeutic options and providing data from a large quantity of patients.Methods The GARY is assembled as a complete survey for all invasive therapies in patients with relevant aortic valve diseases. It evaluates the new therapeutic options and compares them to surgical AVR. The model for data acquisition is based on three data sources: source I, the mandatory German database for external performance measurement; source II, a specific registry dataset; and source III, a follow-up data sheet (generated by phone interview). Various procedures will be compared concerning observed complications, mortality, and quality of life up to 5 years after the initial procedure. Furthermore, the registry will enable a compilation of evidence-based indication criteria and, in addition, also a comparison of all approved operative procedures, such as Ross or David procedures, and the use of different mechanical or biological aortic valve prostheses.Results Since the launch of data acquisition in July 2010, almost all institutions performing aortic valve procedures in Germany joined the registry. By now, 91 sites which perform TAVI in Germany participate and more than 15,000 datasets are already in the registry.Conclusion The implementation of new or innovative medical therapies needs supervision under the conditions of a well-structured scientific project. Up to now relevant data for implementation of TAVI and long-term results are missing. In contrast to randomized controlled trials, GARY is a prospective, controlled, 5-year observational multicenter registry, and a real world investigation with only one exclusion criterion, the absence of patients' written consent.

RESUMO

PURPOSE: To compare the dose distributions from HDR brachytherapy using interstitial catheter implants and Intracavitary Savi applicator for breast cancer patients following lumpectomy. METHODS: We have treated over 200 post lumpectomy breast patients with brachytherapy and Savi applicator (Cianna Medical) . The interstitial technique used a custom built template for placement of catheters under the image guidance. The Savi applicator was placed into the resected cavity and the applicator was expanded to cover the cavity under CT image guidance. The criteria used for plan evaluation was prescription dose covered 95 to 100% of the volume 1.5× prescribed dose to cover <30% of the PTV and 2.0 × prescribed dose covered <10% of the PTV. The Savi plans were evaluated with PTVeval to cover 90 to 95% of the prescribed dose and 1.5×PTVeval not to exceed 50cc, 2×PTVeval to cover <10% of volume. RESULTS: The PTV for interstitial ranged from 29 to 170cc, and that for Savi the PTVeval varied from 28 to 111. For interstitial the 1.5× dose reference expressed as % of PTV varied from 11% to 30% with a median at 24.9%. For Savi the 1.5× dose reference volume expressed as % of PTVeval ranged from 30 to 50% with a median of 40%. The 2× dose reference covered volume expressed as % of PTV varied from 5.5 to 30% of PTV at a median value of 8.5%. The same for Savi varied from 13 to 31% at a median value of 19.4%. The skin dose for interstitial implant was less than 70% whereas same for Savi application was <100%Conclusions: We conclude that the dose uniformity for V1.5 and V2 were better with interstitial implant as compared to Savi application. Also the interstitial implant allowed covering the desired margin of resection without restriction imposed due to air gap. Savi application, being less invasive was better preference by the patient over interstitial.

RESUMO

BACKGROUND: The aim of this post hoc study was to evaluate the association of substance use disorders (SUD) and residential neighborhood affiliation in a group of patients with minor injuries presenting to an inner-city emergency room (ER) in Berlin. METHODS: A total of 2,716 patients with minor injuries presenting to the ER were evaluated concerning alcohol use disorders (AUDIT, cut-off: males 8 points, females 5 points), smoking status, and illicit drug use in the past year. Information about residential area (zip code) and sociodemographics (paper-pencil questionnaire) were also obtained. RESULTS: With respect to residential area, significant differences concerning SUD were identified: from the perspective of the inner-city ER, living close to the ER was associated with substance misuse. Here, alcohol use disorders (AUD), smokers, and illicit drug use were found more frequently compared to patients living in the periphery of the city. In addition, patients living close to the ER were more often unemployed, had a lower income, or were students. CONCLUSION: There are differences in SUD with respect to residential area. However, in order to be able to draw reliable conclusions, an approach collecting representative data at the city district level as well as using a multicenter approach at the city ER level is necessary.
