Abstract
Cystic echinococcosis (CE) is a global health concern caused by cestodes, posing diagnostic challenges due to nonspecific symptoms and inconclusive radiographic results. Diagnosis relies on histopathological evaluation of affected tissue, demanding comprehensive tools. In this retrospective case study, Fourier transform infrared microscopy was explored for detecting and identifying CE through biochemical changes in human tissue sections. Tissue samples from 11 confirmed CE patients were analyzed. Archived FFPE blocks were cut and stained, and then CE-positive unstained sections were examined using Fourier transform infrared microscopy post-deparaffinization. Results revealed the method's ability to distinguish echinococcus elements from human tissue, irrespective of organ type. This research showcases the potential of mid-infrared microscopy as a valuable diagnostic tool for CE, offering promise in enhancing diagnostic precision in the face of the disease's complexities.

Abstract
The present study presents an alternative analytical workflow that combines mid-infrared (MIR) microscopic imaging and deep learning to diagnose human lymphoma and differentiate between small and large cell lymphoma. We could show that using a deep learning approach to analyze MIR hyperspectral data obtained from benign and malignant lymph node pathology results in high accuracy for correct classification, learning the distinct region of 3900 to 850 cm-1 . The accuracy is above 95% for every pair of malignant lymphoid tissue and still above 90% for the distinction between benign and malignant lymphoid tissue for binary classification. These results demonstrate that a preliminary diagnosis and subtyping of human lymphoma could be streamlined by applying a deep learning approach to analyze MIR spectroscopic data.

Abstract
INTRODUCTION We analyzed the expression of PD-L1 in human lymphomas using hyperspectral imaging (HSI) compared to visual assessment (VA) and conventional digital image analysis (DIA) to strengthen further the value of HSI as a tool for the evaluation of brightfield-based immunohistochemistry (IHC). In addition, fluorescent multiplex immunohistochemistry (mIHC) was used as a second detection method to analyze the impact of a different detection method. MATERIAL AND METHODS 18 cases (6 follicular lymphomas and 12 diffuse large B-cell lymphomas) were stained for PD-L1 by IHC and for PD-L1, CD3, and CD8 by fluorescent mIHC. The percentage of positively stained cells was evaluated with VA, HSI, and DIA for IHC and VA and DIA for mIHC. Results were compared between the different methods of detection and analysis. RESULTS An overall high concordance was found between VA, HSI, and DIA in IHC (Cohens Kappa = 0.810VA/HSI, 0.710 VA/DIA, and 0.516 HSI/DIA) and for VAmIHCversus DIAmIHC (Cohens Kappa = 0.894). Comparing IHC and mIHC general agreement differed depending on the methods compared but reached at most a moderate agreement (Coheńs Kappa between 0.250 and 0.483). This is reflected by the significantly higher percentage of PD-L1+ cells found with mIHC (pFriedman = 0.014). CONCLUSION Our study shows a good concordance for the different analysis methods. Compared to VA and DIA, HSI proved to be a reliable tool for assessing IHC. Understanding the regulation of PD-L1 expression will further enlighten the role of PD-L1 as a biomarker. Therefore it is necessary to develop an instrument, such as HSI, which can offer a reliable and objective evaluation of PD-L1 expression.

Abstract
INTRODUCTION To implement Hyperspectral Imaging (HSI) as a tool for quantifying inflammatory cells in tissue specimens by the example of myocarditis in a collective of forensic patients. MATERIAL AND METHODS 44 consecutive patients with suspected myocardial inflammation at autopsy, diagnosed between 2013 and 2018 at the Institute of ForensicMedicine, Medical University of Innsbruck, were selected for this study. Using the IMEC SNAPSCAN camera, visible and near infrared hyperspectral images were collected from slides stained with CD3 and CD45 to assess quantity and spatial distribution of positive cells. Results were compared with visual assessment (VA) and conventional digital image analysis (DIA). RESULTS Finally, specimens of 40 patients were evaluated, of whom 36 patients (90%) suffered from myocarditis, two patients (5%) had suspected healing/healed myocarditis, and two did no have myocarditis (5%). The amount of CD3 and CD45 positive cells did not differ significantly between VA, HSI, and DIA (pVA/HSI/DIA = 0.46 for CD3 and 0.81 for CD45). Coheńs Kappa showed a very high correlation between VA versus HSI, VA versus DIA, and HSI versus DIA for CD3 (Coheńs Kappa = 0.91, 1.00, and 0.91, respectively). For CD45 an almost as high correlation was seen for VA versus HSI and HSI versus DIA (Coheńs Kappa = 0.75 and 0.70) and VA versus DIA (Coheńs Kappa = 0.89). CONCLUSION HSI is a reliable and objective method to count inflammatory cells in tissue slides of suspected myocarditis. Implementation of HSI in digital pathology might further expand the possibility of a sophisticated method.

Abstract
Information, archives, and intelligent artificial systems are part of everyday life in modern medicine. They already support medical staff by mapping their workflows with shared availability of cases' referral information, as needed for example, by the pathologist, and this support will be increased in the future even more. In radiology, established standards define information models, data transmission mechanisms, and workflows. Other disciplines, such as pathology, cardiology, and radiation therapy, now define further demands in addition to these established standards. Pathology may have the highest technical demands on the systems, with very complex workflows, and the digitization of slides generating enormous amounts of data up to Gigabytes per biopsy. This requires enormous amounts of data to be generated per biopsy, up to the gigabyte range. Digital pathology allows a change from classical histopathological diagnosis with microscopes and glass slides to virtual microscopy on the computer, with multiple tools using artificial intelligence and machine learning to support pathologists in their future work.

Abstract
AIMS The purpose of this study was to analyze the incidence of the different ultrasound phenotypes of developmental dysplasia of the hip (DDH), and to determine their subsequent course. PATIENTS AND METHODS A consecutive series of 28 092 neonates was screened and classified according to the Graf method as part of a nationwide surveillance programme, and then followed prospectively. Abnormal hips were followed until they became normal (Graf type I). Type IIb hips and higher grades were treated by abduction in a Tübinger orthosis until normal. Dislocated hips underwent closed or open reduction. RESULTS Overall, 90.2% of hips were normal at birth. Type IIa hips (8.9%) became normal at a median of six weeks (interquartile range (IQR) 6 to 9). Type IIc and IId hips (0.67%) became normal after ten weeks (IQR 7 to 13). There were 19 type lll and eight type lV hips at baseline. There were 24 closed reductions and one open reduction. No late presentations of DDH were detected within the first five years of life. CONCLUSION The incidence of DDH was eight per 1000 live births. The treatment rate was 1% (n = 273). The rate of first operations on the newborn hip was 0.86, and rate of open surgery was 0.04. The cumulative rate of open surgery was 0.07. The authors take the view that early identification and treatment in abduction of all dysplastic hips in early childhood reduces the rate of open reduction and secondary DDH-related surgery later in life.

Abstract
New developments in Mid-infrared microscopic imaging instrumentation and data analysis have turned this method into a conventional technique. This imaging method offers a global analysis of samples, with a resolution close to the cellular level enabling the acquisition of local molecular expression profiles. It is possible to get chemo-morphological information about the tissue status, which represents an essential benefit for future analytical interpretation of pathological changes of tissue. In this review, we give an overview of Mid-infrared microscopic imaging and its applications in clinical research.

Abstract
OBJECTIVES To assess the additional diagnostic value of 18F-fluorocholine PET imaging in preoperative localization of pathologic parathyroid glands in clinically manifest hyperparathyroidism in case of negative or conflicting ultrasound and scintigraphy results. METHODS A retrospective, single-institution study of 26 patients diagnosed with hyperparathyroidism. In cases where ultrasound and scintigraphy failed to detect the location of an adenoma in order to allow a focused surgical approach, an additional 18F-fluorocholine PET scan was performed and its results were compared with the intraoperative findings. RESULTS A total of 26 patients underwent 18F-fluorocholine PET/CT (n = 11) or PET/MRI (n = 15). Adenomas were detected in 25 patients (96.2%). All patients underwent surgery, and the location predicted by PET hybrid imaging was confirmed intraoperatively by frozen section and adequate parathyroid hormone drop after removal. None of the patients needed revision surgery during follow-up. CONCLUSIONS These results demonstrate that 18F-fluorocholine PET imaging is a highly accurate method to detect parathyroid adenomas even in case of previous localization failure by other imaging examinations. KEY POINTS • With 18 F-fluorocholine PET imaging, parathyroid adenomas could be detected in 96.2%. • 18 F-fluorocholine imaging is a highly accurate method to detect parathyroid adenomas. • We encourage its use, where ultrasound fails to detect an adenoma.

Abstract
Background Genetic and epidemiologic evidence suggests that in horses, as in other species, different manifestations of hypersensitivity may occur together. Hypothesis Horses affected with insect bite hypersensitivity (IBH) show airway hyperreactivity (AH) to inhaled histamine, even in the absence of overt clinical signs of equine asthma (EA). Animals Twenty‐two healthy controls (group C), 24 horses suffering from IBH alone (group IBH), and 23 horses suffering from IBH and EA (group IBH/EA). Methods The clinical histories were assessed using 2 standardized questionnaires, the Horse Owner Assessed Respiratory Signs Index (HOARSI), and IBH scoring. Horses were classified as EA‐affected if their HOARSI was >1 and as IBH‐affected if IBH score was >0. Confounding disorders were excluded by clinical examination. The arterial partial pressure of oxygen (PaO2) was measured and flowmetric plethysmography used to assess airway reactivity to increasing doses of inhaled histamine. Results The median histamine provocation concentration (PC) when ∆flow values increased by 35% (PC35) was significantly higher in group C (5.94 [1.11–26.33] mg/mL) compared to group IBH (2.95 [0.23–10.13] mg/mL) and group IBH/EA (2.03 [0.43–10.94] mg/mL; P < 0.01). The PC50 and PC75 showed very similar differences between groups. Furthermore, PaO2 was significantly lower in group IBH (84 ± 8 mmHg) and group IBH/EA (78 ± 11 mmHg) compared to group C (89 ± 6 mmHg; P < 0.01). Conclusions and Clinical Importance IBH is associated with AH and decreased PaO2, even in the absence of overt respiratory clinical signs.

Abstract
Recurrent Clostridium difficile infection (CDI) is a consequence of intestinal dysbiosis and is particularly common following hematopoietic stem cell transplantation (HSCT). Fecal microbiota transplantation (FMT) is an effective method of treating CDI by correcting intestinal dysbiosis by passive transfer of healthy donor microflora. FMT has not been widely used in immunocompromised patients, including HSCT recipients, owing to concern for donor-derived infection. Here, we describe initial results of an FMT program for CDI at a US HSCT center. Seven HSCT recipients underwent FMT between February 2015 and February 2016. Mean time post HSCT was 635 days (25-75 interquartile range [IQR] 38-791). Five of the patients (71.4%) were on immunosuppressive therapy at FMT; 4 had required long-term suppressive oral vancomycin therapy because of immediate recurrence after antibiotic cessation. Stool donors underwent comprehensive health and behavioral screening and laboratory testing of serum and stool for 32 potential pathogens. FMT was administered via the naso-jejunal route in 6 of the 7 patients. Mean follow-up was 265 days (IQR 51-288). Minor post-FMT adverse effects included self-limited bloating and urgency. One patient was suspected of having post-FMT small intestinal bacterial overgrowth. No serious adverse events were noted and all-cause mortality was 0%. Six of 7 (85.7%) patients had no recurrence; 1 patient recurred at day 156 post FMT after taking an oral antibiotic and required repeat FMT, after which no recurrence has occurred. Diarrhea was improved in all patients and 1 patient with gastrointestinal graft-versus-host disease was able to taper off systemic immunosuppression after FMT. With careful donor selection and laboratory screening, FMT appears to be a safe and effective therapy for CDI in HSCT patients and may confer additional benefits. Larger studies are necessary to confirm safety and efficacy and explore other possible effects.

Abstract
SummaryThe haemophilic arthropathy affects the function of the knee joint muscles. The aim of this study was to investigate the myoelectrical signal of knee joint muscles in different age stages during upright standing. Surface EMG (SEMG) amplitudes of quadriceps, hamstrings and gastrocnemii were measured in 191 patients with severe haemophilia A (n=164) and B (n=27) while standing on an even surface. After an age-based classification of patients into the subgroups HA: 17–29 (n = 37), HB: 30–39 (n = 50), HC: 40–49 (n = 61), HD: 50–70 in years (n = 43) the clinical WFH score for the ankle and knee joint was determined. To normalize the SEMG values amplitude ratios (percentage of cumulated activity) were calculated with respect to the specific limb. With increasing age, the patient showed descriptively a deterioration of the joint situation. The extensors of the knee joint reached significantly higher absolute and percentage levels in the muscle activity with increasing age (p < 0.05). The absolute amplitude values of the Mm. gastrocnemii showed no differences in the age groups while the relative levels were decreased.The present study shows that patients with increasing age and degree of haemophilic arthro pathy deve lop a modified control strategy during upright standing, in the form of a shift from the plantar flexors to the extensors of the knee joint.

Abstract
The technique of protoplast fusion has been applied to the problem of unstable diploidy in the yeast Kluyveromyces lactis. By protoplast fusion between heterothallic strains of like mating-type, sporulation-deficient hybrids can be obtained. Biochemical, cytological, and genetical characterisation of these hybrids suggests that the majority of fusion products are diploid. Sporulating hybrids can be constructed by protoplast fusion between homothallic strains. Tetrad analysis of these hybrids demonstrates conclusively the diploid nature of fusion products.

Abstract
Measuring local temperature with a spatial resolution on the order of a few nanometers has a wide range of applications in the semiconductor industry and in material and life sciences. For example, probing temperature on the nanoscale with high precision can potentially be used to detect small, local temperature changes like those caused by chemical reactions or biochemical processes. However, precise nanoscale temperature measurements have not been realized so far owing to the lack of adequate probes. Here we experimentally demonstrate a novel nanoscale temperature sensing technique based on optically detected electron spin resonance in single atomic defects in diamonds. These diamond sensor sizes range from a micrometer down to a few tens of nanometers. We achieve a temperature noise floor of 5 mK/Hz(1/2) for single defects in bulk sensors. Using doped nanodiamonds as sensors the temperature noise floor is 130 mK/Hz(1/2) and accuracies down to 1 mK for nanocrystal sizes and therefore length scales of a few tens of nanometers. This combination of precision and position resolution, combined with the outstanding sensor photostability, should allow the measurement of the heat produced by chemical interactions involving a few or single molecules even in heterogeneous environments like cells.

Abstract
OBJECTIVES Fractures of the medial humeral epicondyle represent approximately 10 % of all paediatric elbow fractures. material and methods: Surgically treated paediatric fractures of the medial humeral epicondyle were analysed retrospectively for their epidemiological, clinical and surgical parameters. Re-evaluation included clinical function, satisfaction, pain level and MAYO elbow performance score (MEPS). RESULTS 22 children could be included. A re-evaluation of 91 % of our patients after a follow-up of ∅ 4 years (range: 1-9 years; median: 4 years) after initial surgery was possible. Subjective outcome and objective function were good with moderate limitations. 85 % of our patients showed good to excellent results in the MEPS. CONCLUSION Regarding our own good clinical results and potentially lower rates of pseudarthrosis - in comparison to conservatively treated patients - by trend we recommend internal fixation in paediatric fractures of the medial humeral epicondyle. However, operative or conservative treatment must be indicated individually together with the patient and his/her parents.

Abstract
Abstract
Cancer evolution involves cycles of genomic damage, epigenetic deregulation, and increased cellular proliferation that eventually culminate in the carcinoma phenotype. Early breast neoplasias include usual ductal hyperplasia, columnar cell lesions, and flat epithelial atypia and some are thought to represent precursor stages. To elucidate their role in cancer evolution we performed comparative whole genome sequencing of early neoplasias, matched normal tissue, and carcinomas from six patients. The identified somatic mutations served as lineage markers to build trees that relate the tissue samples. On the basis of the lineage trees we inferred the order, timing, and rates of mutational events. We find that in a subset of cases, the last common ancestor of an early neoplasm and a carcinoma was hypermutated and had several aneuploidies, and that evolution further accelerated in the carcinoma lineage. In contrast to highly advanced tumors that are the focus of much of current cancer genome sequencing, the early neoplasia genomes, and the carcinomas as well, harbor a striking paucity of potentially functional somatic point mutations. The earliest significant events we could detect, those changes that occurred in common ancestors of neoplastic and tumor cells, are aneuploidies. Several aneuploidies are recurrent, suggesting that they are among the earliest genomic events that predispose breast tissue to eventual development of invasive carcinoma.

Abstract
BACKGROUND About 80 % of all paediatric distal humerus fractures are supracondylar fractures. PATIENTS AND METHODS Surgically treated children with supracondylar humeral fractures between 2000-2008 were analysed retrospectively and re-evaluated for function, satisfaction, pain level and with the MAYO elbow performance score (MEPS). RESULTS 46 patients were included. Open fractures (2 %) and vessel (0 %) or nerve (4 %) lacerations were rare, additional forearm fractures frequent (15 %). Surgery was done by closed/open reduction and crossed K-wire pinning. Main complications were movement restriction and K-wire migration. All fractures healed. 72 % of patients could be re-evaluated Ø 51 months after surgery. The mean differences between non-affected and affected elbows showed 8° for flexion, 1° for extension, 1° for pronation and 0° for supination. In 88 % excellent or good results could be measured with the MEPS. CONCLUSION Regarding bony healing in all patients, well manageable complications, mostly excellent or good results in the MEPS and good function, crossed K-wire pinning after closed/open reduction is a safe standard surgical procedure for this type of fracture.

Abstract
OBJECTIVE Closed reduction and minimally invasive stabilization of proximal humeral shaft fractures with long PHILOS plates. The presented technique enables stable extramedullary fixation of the fractures without affecting surrounding nerves. INDICATIONS Proximal humeral shaft fractures that may not be fixed by intramedullary nailing because of a narrow, deformed or occupied intramedullary canal or because of open growth plates. CONTRAINDICATIONS Fractures that may not be reduced adequately by traction or with percutaneous techniques. Furthermore, fractures with delayed or nonunion and pseudarthrosis should not be treated with this technique. SURGICAL TECHNIQUE An anterolateral delta split approach is used to create an epiperiosteal tunnel along the humeral shaft from proximally to distally. A second incision is made distally at the lateral border of the biceps muscle. The brachialis muscle is dissected longitudinally. The PHILOS plate is twisted so that the proximal part of the plate can be placed laterally and the distal part anterolaterally at the humeral shaft. The plate is inserted into the epiperiostal tunnel and fixed with percutaneous screws. POSTOPERATIVE MANAGEMENT The arm is immobilized in a Gilchrest bandage until wounds are healed. Active-assisted physiotherapeutic mobilization without loading starts on the first postoperative day. Active mobilization starts 8-12 weeks postoperatively. In cases of soft tissue irritation the PHILOS plate may be removed after 1 year. RESULTS Between 2005 and 2011 a total of 16 patients (8 women and 8 men) were treated with the presented technique. The patients mean age was 61 years. According to the AO classification, five fractures were classified as type A, eight as type B and three fractures as type C. All patients had clinical and radiological follow-up examinations after a mean of 24 months (12-38 months). All fractures showed complete bony consolidation at the final follow-up. The mean Constant-Murley score was 81 points representing 84% of the Constant-Murley score of the healthy contralateral shoulder. The average DASH score was 33 points and the mean SF36 was 85 points.

Abstract
Recently the relevance of femoroacetabular impingement as a cause of hip and groin pain in sportsmen has been recognized. The entity often poses diagnostic and therapeutic problems to the sports physician. The patients go through an odyssey of different diagnostic and therapeutic modalities before the correct diagnosis is made and an adequate therapy is implemented. Not seldom, patients get even operated at another site which is thought to cause the problems. The present review analyzes the current literature concerning diagnostic standards and therapy of femoroacetabular impingement focussing on their relevance for sports medicine. It is aimed to help the sports physician to recognise this entity as a cause for groin and hip pain in the athlete and realise its importance for the short term performance of the athlete and its long term significance in terms of development of early hip osteoarthrosis.

Abstract
The β-angle is a radiological tool for measuring the distance between the pathological head-neck junction and the acetabular rim with the hip in 90° of flexion in patients with femoroacetabular impingement. Initially it was measured using an open-chamber MRI. We have developed a technique to measure this angle on plain radiographs. Correlation analysis was undertaken to determine the relationship between the range of movement and the β-angle in 50 patients with femoroacetabular impingement and 50 asymptomatic control subjects. Inter- and intra-observer reliability of the β-angle was also evaluated. Patients with femoroacetabular impingement had a significantly smaller (p < 0.001) mean β-angle (15.6°, 95% confidence interval (CI) 13.3 to 17.7) compared with the asymptomatic group (38.7°, 95% CI 36.5 to 41.0). Correlation between internal rotation and the β-angle was high in the impingement group and moderate in the asymptomatic group. The β-angle had excellent inter- and intra-observer reliability in both groups. Our findings suggest that the measurement of the β-angle on plain radiography may represent a valid, reproducible and cost-effective alternative to open MRI in the assessment of the pathological bony anatomy in patients with cam, pincer and mixed femoroacetabular impingement.

Abstract
We evaluated the impact of stereo-visualisation of three-dimensional volume-rendering CT datasets on the inter- and intraobserver reliability assessed by kappa values on the AO/OTA and Neer classifications in the assessment of proximal humeral fractures. Four independent observers classified 40 fractures according to the AO/OTA and Neer classifications using plain radiographs, two-dimensional CT scans and with stereo-visualised three-dimensional volume-rendering reconstructions. Both classification systems showed moderate interobserver reliability with plain radiographs and two-dimensional CT scans. Three-dimensional volume-rendered CT scans improved the interobserver reliability of both systems to good. Intraobserver reliability was moderate for both classifications when assessed by plain radiographs. Stereo visualisation of three-dimensional volume rendering improved intraobserver reliability to good for the AO/OTA method and to excellent for the Neer classification. These data support our opinion that stereo visualisation of three-dimensional volume-rendering datasets is of value when analysing and classifying complex fractures of the proximal humerus.

Abstract
BACKGROUND AND AIMS CD44 and its splice variants can be expressed on all leukocytes, conferring adhesive properties and enhancing cellular recruitment to the endothelium during inflammation. CD44 expression is increased in inflammatory conditions such as rheumatoid arthritis and CD44 variant 3 (CD44v3) expression may be associated with inflammation. We have examined CD44 and CD44v3 expression on peripheral blood monocytes from patients with peripheral arterial disease (PAD) and healthy controls. We have also examined the effect of fish oil supplementation on these markers. METHODS AND RESULTS CD44 and CD44v3 were assessed at baseline and following dietary supplementation with fish oil for 12 weeks in both PAD and control groups. Monocytes from PAD patients had higher CD44 expression than those from controls (median intensity fluorescence (MIF): 480+/-278 vs 336+/-251 (mean+/-SD); p<0.001). Following 12 weeks' dietary supplementation with fish oil, CD44 expression was reduced in PAD patients (MIF: 480+/-278 vs 427+/-262; p=0.05) but not in controls (336+/-251 vs 355+/-280; ns). Monocyte CD44v3 expression was lower in cultured monocytes from PAD patients compared to those from controls (0.15+/-0.15 vs 0.22+/-0.14 OD units; p<0.02). This was increased in the PAD group following fish oil supplementation (0.15+/-0.14 to 0.27+/-0.23 OD units; p<0.001). CONCLUSION Monocyte CD44 and CD44v3 expression are altered in arterial disease but are returned towards levels seen in control subjects by dietary fish oil supplementation.
