Abstract
BACKGROUND Glioblastoma is a malignant and aggressive type of central nevous system malignancy characterized by many distinct biological features including extensive hypoxia. Hypoxia in glioblatoma associates with complex signaling patterns including activation of several pathways such as MAPK, PI3K-AKT/mTOR and IL-6/JAK/STAT3 with the master regulator HIF-1, which in turn drive particular tumor behaviors determining, in the end, treatment outcomes and patients fate. Thus, the present study was designed to investigate the expression of selected hypoxia related factors including STAT3 in a small set of long-term surviving glioma patients. METHODS The expression of selected hypoxia related factors including STAT3 was evaluated in a time series of formalin fixed paraffin embedded and cryopreserved glioma samples from repeatedly resected patients. In addition, comparative studies were also conducted on primary glioma cells derived from original patient samples, stabilized glioma cell lines and tumor-xenograft mice model. Obtained data were correlated with clinical findings too. RESULTS Glioblastoma samples of the analyzed patients displayed heterogeneity in the expression of hypoxia- related and EMT markers with most interesting trend being observed in pSTAT3. This heterogeneity was subsequently confirmed in other employed models (primocultures derived from glioblastoma tissue resections, cryopreserved tumor specimens, stabilized glioblastoma cell line in vitro and in vivo) and concerned, in particular, STAT3 expression which remained stable. In addition, subsequent studies on the role of STAT3 in the context of glioblastoma hypoxia demonstrated opposing effects of its deletion on cell viability as well as the expression of hypoxia and EMT markers. CONCLUSIONS Our results suport the importance of STAT3 expression and activity in the context of hypoxia in malignant glioblastoma long-term surviving glioma patients while emphasizing heterogeneity of biological outcomes in varying employed tumor models.

Abstract
Hand2 is a core transcription factor responsible for chromaffin cell differentiation. However, its potential utility in surgical pathology has not been studied. Thus, we aimed to investigate its expression in paragangliomas, other neuroendocrine neoplasms (NENs), and additional non-neuroendocrine tumors. We calibrated Hand2 immunohistochemistry on adrenal medulla cells and analyzed H-scores in 46 paragangliomas (PGs), 9 metastatic PGs, 21 cauda equina neuroendocrine tumors (CENETs), 48 neuroendocrine carcinomas (NECs), 8 olfactory neuroblastomas (ONBs), 110 well-differentiated NETs (WDNETs), 10 adrenal cortical carcinomas, 29 adrenal cortical adenomas, 8 melanomas, 41 different carcinomas, and 10 gastrointestinal stromal tumors (GISTs). Both tissue microarrays (TMAs) and whole sections (WSs) were studied. In 171 NENs, previously published data on Phox2B and GATA3 were correlated with Hand2. Hand2 was positive in 98.1% (54/55) PGs, but only rarely in WDNETs (9.6%, 10/104), CENETs (9.5%, 2/21), NECs (4.2%, 2/48), or ONBs (12.5%, 1/8). Any Hand2 positivity was 98.1% sensitive and 91.7% specific for the diagnosis of PG. The Hand2 H-score was significantly higher in primary PGs compared to Hand2-positive WDNETs (median 166.3 vs. 7.5; p < 0.0001). Metastatic PGs were positive in 88.9% (8/9). No Hand2 positivity was observed in any adrenal cortical neoplasm or other non-neuroendocrine tumors, with exception of 8/10 GISTs. Parasympathetic PGs showed a higher Hand2 H-score compared to sympathetic PGs (median H-scores 280 vs. 104, p < 0.0001). Hand2 positivity in NENs serves as a reliable marker of primary and metastatic PG, since other NENs only rarely exhibit limited Hand2 positivity.

Abstract
Colorectal cancer (CRC) is the fourth most commonly diagnosed malignant condition in the world. Micro RNAs (miRNAs) as well as epithelial to mesenchymal transition (EMT) play an important role in the pathogenesis of CRC. We performed a comparative analysis of the expression of selected miRNA genes and EMT markers in bioptic samples from patients (n = 45) with primary CRC or metastatic (m)CRC to the regional lymph node using reverse transcription-quantitative PCR and IHC staining. Results: Out of all miRNA analyzed, the miR-17 expression was most significantly different and associated with lower risk of CRC spread to the lymph node. In addition, significant relationships were found between the tumor side localization and several miRNAs expressions (miR-9, miR-29b, miR-19a, miR-19b, miR-21, miR-106a, miR-20a and miR-17). In addition, of the examined EMT markers, only VEGFA expression correlated with tumor progression (tumor grade G2). In the examined set of patient samples and their matched healthy tissue, several specific molecular markers (miRNAs associated with EMT and tumor progression) were identified with a promising prognostic potential. Their further examination in larger patient cohorts is planned to validate the present data.

Abstract
Diagnosis of soft tissue tumors is often challenging, given the large number of entities, often with non-specific or overlapping morphology. Although morphology still plays an important part in diagnostic process, additional studies including immunohistochemistry and molecular genetics are often needed to arrive at correct diagnosis. We report a case of 61-year-old male with subcutaneous tumor in right hip area, that was surgically removed. The tumor was composed of uniform bland spindle cells in mild to moderately cellular myxoid nodules, with limited areas of collagenization and the diagnosis of low grade fibromyxoid sarcoma was made. The tumor recurred 3 years after the initial diagnosis and the new sample showed a high-grade round cell sarcoma with limited residual low-grade areas and non-specific immunoprofile after extended immunohistochemical work-up. Molecular analysis demonstrated ZC3H7B::BCOR fusion. Sarcomas with ZC3H7B::BCOR fusion occurring outside of uterus are exceedingly rare. A comprehensive review of previously published cases and a short discussion about classification of the entity is provided, together with data about morphology and immunoprofile of the lesions. The case also underscores the necessity of extended work up of soft tissue tumors with unusual immunohistochemical or morphological features in order to accurately assess their biological potential.

Abstract
HoxB13 is a transcription factor involved in defining of posterior endodermal derivatives, including prostate and rectum. While it is used as a marker of prostatic adenocarcinoma, it has not been studied systematically in neuroendocrine neoplasms. Thus, we performed HoxB13 immunohistochemistry in tissue microarrays and the whole sections of 232 neuroendocrine neoplasms. These included 34 paragangliomas (PGs), 20 cauda equina neuroendocrine tumors (CENETs), 123 well-differentiated neuroendocrine tumors (WDNETs), and 55 neuroendocrine carcinomas (NECs). WDNETs were additionally analyzed with SATB2, and colorectal WDNETs with CDX2 and serotonin immunohistochemistry. In total, HoxB13 immunoreactivity was observed in 95% (19/20) CENETs, 10.6% (13/123) WDNETs, and 12.9% (7/54) NECs. No PGs were positive. Large intestine WDNETs expressed HoxB13 in 68.4% (13/19); five negative tumors originated in cecum and one in rectum. In rectum, 92.9% (13/14) WDNETs expressed HoxB13. HoxB13 was 92.9% sensitive and 100% specific, showing 100% positive predictive value for the rectal origin of WDNET. In NECs, HoxB13 was positive in 15.4% (2/13) GIT tumors and 80% (4/5) prostatic NECs, but in none of urinary bladder NECs (0/8). SATB2 was positive in 17.1% (21/123) WDNETs, including 78.9% (15/19) of colorectal WDNETs, 71.4% (5/7) appendiceal WDNETs, and 2.9% (1/34) small intestine WDNETs. All 4 SATB2-negative large bowel tumors originated in the cecum. When both markers combined, HoxB13+/SATB2+ immunoprofile was seen exclusively in rectal WDNETs (positive predictive value 100%), while HoxB13-/SATB2+ immunoprofile was highly suggestive of the appendiceal origin (positive predictive value 71.4%). Therefore, HoxB13 can be useful as an immunohistochemical marker of rectal WDNETs and prostatic NECs.

Abstract
Histological identification of dispersed glioma cells in small biopsies can be challenging, especially in tumours lacking the IDH1 R132H mutation or alterations in TP53. We postulated that immunohistochemical detection of proteins expressed preferentially in gliomas (EGFR, MEOX2, CD34) or during embryonal development (SOX11, INSM1) can be used to distinguish reactive gliosis from glioma. Tissue microarrays of 46 reactive glioses, 81 glioblastomas, 34 IDH1-mutant diffuse gliomas, and 23 gliomas of other types were analysed. Glial neoplasms were significantly more often (p < 0.001, χ2) positive for EGFR (34.1% vs. 0%), MEOX2 (49.3% vs. 2.3%), SOX11 (70.5% vs. 20.4%), and INSM1 (65.4% vs. 2.3%). In 94.3% (66/70) of the glioblastomas, the expression of at least two markers was observed, while no reactive gliosis showed coexpression of any of the proteins. Compared to IDH1-mutant tumours, glioblastomas showed significantly higher expression of EGFR, MEOX2, and CD34 and significantly lower positivity for SOX11. Non-diffuse gliomas were only rarely positive for any of the five markers tested. Our results indicate that immunohistochemical detection of EGFR, MEOX2, SOX11, and INSM1 can be useful for detection of glioblastoma cells in limited histological samples, especially when used in combination.

Abstract
Solitary fibrous tumours (SFTs) may show unusual morphologies and in such circumstances, unexpected immunoprofile can be misleading. Following an index case of myxoid meningeal SFT with neuroendocrine immunoprofile, we decided to assess a neuroendocrine profile in SFTs from various locations. The cohort of 9 meningeal and 28 extrameningeal SFTs was evaluated for CNS WHO grade (G1-G3) and four tiered Demicco risk stratification. Immunohistochemical detection of synaptophysin, chromogranin, INSM1, CD56, and CD57 was performed in each case and semiquantitatively assessed (0 - no expression; 1+ <10% positive; 2+ 11-50%; 3+ >51%); whole sections (meningeal SFTs) or tissue microarray (extrameningeal SFTs) were used for immunohistochemistry. The cohort included 13 men and 24 females. Meningeal SFTs included 5 WHO G1, 3 WHO G2 and 1 WHO G3 tumours. Extrameningeal SFTs included 21 low-risk, 4 intermediate risk and 2 high risk tumours. INSM1 immunoreactivity was observed in 12/37 cases (32%, 8 cases 1+, 3 cases 2+, 1 case 3+); synaptophysin was positive in 6/35 cases (19%, 5 cases 1+, 1 case 2+); CD56 was positive in 20/37 (54%, 16 cases 1+, 3 cases 2+ and 1 case 3+) and CD57 was expressed in 14/36 cases (39%, 5 cases 1+, 4 cases 2+ and 5 cases 3+). Chromogranin positivity was not observed. No significant association was observed between expression of neuroendocrine markers and tumour grade, Demicco risk group or meningeal and extrameningeal location. Extrapleural SFTs showed tendency for positivity of INSM1 (p=0.014, χ2) and CD57 (p=0.017, χ2), compared to pleural SFTs.

Abstract
Both musculoskeletal gossypibomas and chronic expanding hematomas have been rarely reported; the reports that do exist are usually case reports. Our objective is to demonstrate problematic imaging diagnostics of an unusual presentation mimicking a malignant lesion. We report the case of a 47-year-old man who underwent bone graft harvesting from the iliac crest for spinal fusion due to scoliosis at 18 years of age, and 29 years later, he developed a growing, painful tumor at the original donor site (a bone defect in the iliac crest). It was challenging to differentiate a hematoma from a malignant tumor based solely on clinical and radiological workup, including an ultrasound-guided needle biopsy focused on viable tissue. The definitive diagnosis of a gossypiboma with a chronic expanding hematoma was based on histopathological assessment after wide surgical resection-a chronic expanding hematoma with multiple foamy macrophages and giant cells engulfing foreign material (original surgical hemostatic sponge).

Abstract
Acute traumatic intervertebral disc herniation of the thoracic spine is a rather rare injury with only a few reported cases to date. In this manuscript, we present a case of a 58-year-old male patient who sustained a car accident-related high-energy trauma, resulting in a disc herniation of the thoracic spine. Furthermore, we also discuss the possible implications of late diagnosis of such condition. The patient was initially referred from the Emergency Department as a case of head contusion with a left upper limb paresis. Due to only minimal bony trauma visible on the initial spine CT scan, the neurological deficit was attributed to the cranial trauma. The diagnosis of a traumatic disc herniation was therefore established only after the rapid onset of paraparesis, which gradually progressed into paraplegia, and a following spine MRI scan. Despite the subsequent urgent spinal decompression, the neurological functions of the lower limbs were not restored. This manuscript addresses the indications for performing MRI scans in polytrauma patients with a CT-verified spine trauma. Although it may be complicated to perform routine MRI scans in all such patients in daily practice, it can certainly help diagnose such injuries earlier and thus prevent potential permanent neurological damage to the patients. Key word: spine injury, traumatic disc herniation, thoracic spine, spine surgery.

Abstract
Introduction Metformin-associated lactic acidosis (MALA) is a rare but life-threatening condition. Here, we report the outcome of a patient with MALA complicated by acute coronary syndrome. Case presentation A 47-year-old obese woman of Caucasian ethnicity was admitted for syncope and tachypnea with Kussmaul breathing. She had a type-2 diabetes and was on oral antidiabetic therapy. Hemoglobin A1c was 6.6%. On admission, a severe acute kidney injury (serum creatinine: 1251 µmol/L) with hyperkalemia (7.5 mmol/L) and severe lactic acidosis (ph:7.042, bicarbonate: 9.9 mmol/L, partial pressure of carbon dioxide: 21.8 mmHg, lactate: 20.0 mmol/L) was found. Despite bicarbonate therapy, ph further decreased. Within 2.5 h of admission, a temporary hemodialysis catheter was placed, and one session of a high-efficiency hemodialysis was performed. 8 h after admission, a continuous venovenous hemodiafiltration was initiated and maintained for 2 days. The metformin therapy was stopped. Supplemental oxygen, intravenous catecholamines (4 days) and antibiotic therapy (7 days) were applied. During this therapy of lactic acidosis, an acute coronary syndrome evolved by day 2 after admission and resolved by day 5 in hospital. After recovery, the patient was transferred to a general ward on day 7 and left the hospital on day 11. By discharge, both the acute kidney injury and the acute coronary syndrome were reversible. Conclusion In the patient with MALA complicated by acute coronary syndrome, the combination of a high-efficiency hemodialysis and, consecutively, continuous venovenous hemodiafiltration led to a favorable outcome.

Abstract
The DEAP-3600 detector searches for the scintillation signal from dark matter particles scattering on a 3.3 tonne liquid argon target. The largest background comes from 39 Ar beta decays and is suppressed using pulse-shape discrimination (PSD). We use two types of PSD estimator: the prompt-fraction, which considers the fraction of the scintillation signal in a narrow and a wide time window around the event peak, and the log-likelihood-ratio, which compares the observed photon arrival times to a signal and a background model. We furthermore use two algorithms to determine the number of photons detected at a given time: (1) simply dividing the charge of each PMT pulse by the mean single-photoelectron charge, and (2) a likelihood analysis that considers the probability to detect a certain number of photons at a given time, based on a model for the scintillation pulse shape and for afterpulsing in the light detectors. The prompt-fraction performs approximately as well as the log-likelihood-ratio PSD algorithm if the photon detection times are not biased by detector effects. We explain this result using a model for the information carried by scintillation photons as a function of the time when they are detected.

Abstract
AIMS In somatotroph pituitary neuroendocrine tumours (adenomas), a pattern of cytokeratin (CK) 18 expression is used for tumour subclassification, with possible clinical implications. Rare somatotroph tumours do not express CK 18. We aimed to characterise this subset clinically and histologically. METHODS AND RESULTS Clinical and pathological data for the study were derived from a previously published data set of a cohort of 110 patients with acromegaly. Data included serum levels of insulin-like growth factor 1 (IGF1), growth hormone (GH), prolactin and thyroid-stimulating hormone (TSH), tumour diameter, tumour invasion defined by Knosp grade and immunohistochemical data concerning the expression of Ki67, p53, E-cadherin, somatostatin receptor (SSTR)1, SSTR2A, SSTR3, SSTR5 and D2 dopamine receptor. Additional immunohistochemical analysis (AE1/3, CK 8/18, vimentin, neurofilament light chain, internexin-α) was performed. CK 18 was negative in 10 of 110 (9.1%) tumours. One of these tumours was immunoreactive with CK 8/18 antibody, while the remainder expressed only internexin-α intermediate filament in patterns similar to CK 18 (perinuclear fibrous bodies). CK-negative tumours showed no significant differences with respect to biochemical, radiological or pathological features. They showed significantly higher expression of SSTR2A compared to the sparsely granulated subtype and significantly lower expression of E-cadherin compared to the non-sparsely granulated subtypes of tumours. The tumours showed divergent morphology and hormonal expression: two corresponded to densely granulated tumours and three showed co-expression of prolactin and morphology of either mammosomatotroph or somatotroph-lactotroph tumours. Four tumours showed morphology and immunoprofile compatible with plurihormonal Pit1-positive tumours. CONCLUSIONS CK-negative somatotroph tumours do not represent a distinct subtype of somatotroph tumours, and can be further subdivided according to their morphology and immunoprofile.

Abstract
Spontaneous spinal epidural hematoma (SSEH) is a very rare clinical entity with potential diagnostic difficulties and which can result in severe neurological deficit. The etiology of this rare condition is largely not known, but with potential predisposition in patients on anticoagulation medication. This includes the novel anticoagulants with direct inhibition of the factor Xa mechanism (DOACs). These medications are supposed to have more predictable pharmacokinetics with fewer severe haemorrhagic adverse events in comparison with standard warfarin therapy. However, in the last few years, an increasing number of case reports have been published of haemorrhage into the central nervous system. We present a case of non-traumatic spinal epidural hematoma in the lumbar region in a patient on chronic apixaban therapy. To the best of our knowledge, it is the first described SSEH in the lumbar region associated with apixaban therapy.

Abstract
In somatotroph pituitary tumours, somatostatin analogue (SSA) therapy outcomes vary throughout the studies. We performed an analysis of cohort of patients with acromegaly from the Czech registry to identify new prognostic and predictive factors. Clinical data of patients were collected, and complex immunohistochemical assessment of tumour samples was performed (SSTR1‐5, dopamine D2 receptor, E‐cadherin, AIP). The study included 110 patients. In 31, SSA treatment outcome was evaluated. Sparsely granulated tumours (SGST) differed from the other subtypes in expression of SSTR2A, SSTR3, SSTR5 and E‐cadherin and occurred more often in young. No other clinical differences were observed. Trouillas grading system showed association with age, tumour size and SSTR2A expression. Factors significantly associated with SSA treatment outcome included age, IGF1 levels, tumour size and expression of E‐cadherin and SSTR2A. In the group of SGST, poor SSA response was observed in younger patients with larger tumours, lower levels of SSTR2A and higher Ki67. We observed no relationship with expression of other proteins including AIP. No predictive value of E‐cadherin was observed when tumour subtype was considered. Multiple additional factors apart from SSTR2A expression can predict treatment outcome in patients with acromegaly.

Abstract
Sox2 is one of the transcription factors responsible for the maintenance of stem cell phenotype. It has been implicated as a marker of stem cells in normal pituitaries and pituitary neuroendocrine tumours. To explore the clinical significance of Sox2 expression in histological sections, we performed immunohistochemical detection of Sox2 in 113 pituitary neuroendocrine tumours from 109 patients with acromegaly. In 11 tumours, we performed double immunostaining for Sox2, annexin A1 and S100 protein. Tumours were characterised using the WHO classification system. Proliferative activity and invasion were assessed. The amount of immunoreactive cells was evaluated and correlated with tumour size and biochemical features (levels of IGF1, GH, prolactin, βTSH). Sox2+ cells were identified in 35/38 normal pituitaries adjacent to the tumours. In 36 tumours (33%), ≥ 1% of the cells expressed Sox2, in 24 cases (22%), Sox2+ cells comprised < 1% and 49 cases (45%) were negative. We found no significant differences between Sox2+ and Sox2- groups with respect to the age, initial levels of GH, IGF1, prolactin, βTSH, tumour size, invasion, proliferative activity or histological features. We observed a positive correlation between Sox2+ cell count and βTSH immunoreactive cells (r = 0.459, p < 0.001) that was further verified by multivariate analysis. Using double stain, the majority of Sox2+ cells coexpressed annexin A1 (average 89%) and S100 protein (average 76.2%) and showed morphological features of folliculo-stellate cells. Sox2+ cells are thus commonly present in growth hormone-producing tumours and normal pituitaries, and their amount does not have any prognostic significance. Most of these cells represent a subpopulation of folliculo-stellate cells, pointing out to their role as a possible stem cell population.

Abstract
The 2017 World Health Organization (WHO) classification proposes to type and subtype primary adenohypophyseal tumours according to their cell lineages with the aim to establish more uniform tumour groups. The definition of atypical adenoma was removed in favour of high-risk adenoma, and the assessment of proliferative activity and invasion was recommended to diagnose aggressive tumours. Recently, the International Pituitary Pathology Club proposed to replace adenoma with the term of pituitary neuroendocrine tumour (PitNET) to better reflect the similarities between adenohypophyseal and neuroendocrine tumours of other organs. The European Pituitary Pathology Group (EPPG) endorses this terminology and develops practical recommendations for standardised reports of PitNETs that are addressed to histo- and neuropathologists. This brief report presents the results of EPPG's consensus for the reporting of PitNETs and proposes a diagnostic algorithm.

Abstract
PURPOSE Spindle cell oncocytomas (SCOs) are very rare tumors of the posterior pituitary with potential for locally aggressive behaviour. Their treatment includes surgery and possibly radiotherapy, however other options are lacking. Somatostatin receptors (SSTs) are a possible therapeutic target for somatostatin analogues and their expression has been demonstrated recently in closely related pituicytomas, but there are no data about their presence in SCOs. METHODS We collected five cases of SCO from four patients including one recurrent case. Immunohistochemical detection of TTF1, GFAP, CD68, SST1, SST2, SST3, SST5 and D2 dopamine receptor (D2DR) was performed. Intensity, percentage of positive cells and pattern of expression was evaluated in semiquantitative fashion. Protein expression of SST1-5 and D2DR was further evaluated by western blot. RESULTS Mean patient age was 61.8 years (range 47-71 years) with male to female ratio 1:1. In one patient, samples from the original tumor and its recurrence 16 years later were assessed. TTF1 was positive in all five cases, no expression of GFAP and CD68 was seen. Immunohistochemical expression of SST1 was noted in 1/5 cases, SST2 in 2/5 cases, including recurrent case but not the original case. SST3 was expressed in 3/5 tumors and D2 dopamine receptor in 4/5 cases. Western blot was successfully performed in four samples. SST2, SST3 and D2DR expression was identified in all the samples, including two cases originally negative for SST2 and one case negative for SST3 by immunohistochemistry. The number of positive cells and level of expression varied among different areas of the same tumors. No expression of SST5 was observed. In the patient with the recurrent tumor, intensity of SST2, SST3 and D2DR expression varied between original tumor and its recurrence. CONCLUSIONS We demonstrated presence of different SST subtypes and D2DR in spindle cell oncocytomas. The most commonly expressed subtype was SST2 and SST3, while no expression of SST5 was observed. Expression showed spatial heterogeneity and temporal changes as seen in the recurrent case. The biological meaning of SSTs expression in SCOs is unclear as well as whether it may be exploited in treatment of selected cases.

Abstract
This Letter reports the first results of a direct dark matter search with the DEAP-3600 single-phase liquid argon (LAr) detector. The experiment was performed 2 km underground at SNOLAB (Sudbury, Canada) utilizing a large target mass, with the LAr target contained in a spherical acrylic vessel of 3600 kg capacity. The LAr is viewed by an array of PMTs, which would register scintillation light produced by rare nuclear recoil signals induced by dark matter particle scattering. An analysis of 4.44 live days (fiducial exposure of 9.87 ton day) of data taken during the initial filling phase demonstrates the best electronic recoil rejection using pulse-shape discrimination in argon, with leakage <1.2×10^{-7} (90% C.L.) between 15 and 31 keV_{ee}. No candidate signal events are observed, which results in the leading limit on weakly interacting massive particle (WIMP)-nucleon spin-independent cross section on argon, <1.2×10^{-44} cm^{2} for a 100 GeV/c^{2} WIMP mass (90% C.L.).

Abstract
OBJECTIVE Presentation of a rare finding non-Hodgkin´s B-lymphoma of the ovary in a patient during caesarean section. DESIGN Case report. SETTINGS Department of Obstetrics and Gynaecology, Regional Hospital Liberec, a.s.; First Internal Clinic - Clinic of Hematology, First Faculty of Medicine and General University Hospital, Charles University in Prague; Department of Pathology and Molecular Medicine, Second Faculty of Medicine, Charles University in Praque and Motol University Hospital. RESULTS Pregnant woman, 31-years old, primiparous, with a history of caesarean section was examinated in our department due to nonspecific abdominal pain during her pregnancy. During the caesarean section of fetal indication we found bilateral ovarian tumours. We performed unilateral adnexectomy. Preliminary diagnosis from frozen section was thecoma, but final diagnosis (after definitive histology, imunohistochemistry and molecular investigation) was high-grade B-cell non-Hodgkin´s lymphoma with c-myc and bcl-6 gene rearrangement (double-hit lymphoma) resulting in an unfavourable prognosis. The patient consequently completed 6 cycles of chemotherapy with a biological treatment, and achieved a complete remission. However, after 6 months, an early generalisation to the CNS appeared, leading to intracranial hypertension refractory to anithypertensive and anti-oedematous therapy, consequently leading to death. CONCLUSION Non-Hodgkin´s lymphoma of the ovary in pregnancy is a rare adnexal tumour whose treatment requires interdisciplinary cooperation.

Abstract
BACKGROUND Colorectal carcinoma is one of the most common malignancies in western countries. Among different approaches to its research, primary cancer cell lines can play an important role. AIM The main purposes of this study were: 1) to establish an effective and reproducible method of colorectal cancer cell isolation and cultivation from primary tumours and lymph node metastases and 2) to elucidate the biological features of the tumours favouring successful cell cultivation. MATERIALS AND METHODS The tumour cells were obtained from colectomy specimens. Primary tumour and lymph node metastasis tissue was used for establishing the tissue cultures. Colectomy samples were further processed for routine histopathological assessment: tumour grade, stage, angioinvasion and perineural spread were evaluated. Features of tissue culture cells were assessed using phase contrast microscopy and immune-histochemical techniques. WST-1 assay and X-CELLigence real time analysis were carried out for viability and proliferation testing before and after treatment with irinotecan and oxaliplatin. Molecular features of the tumour including K-RAS/B-RAF/N-RAS mutations were tested using allele-specific PCR. Results of the cultivation process were compared to the histopathological and molecular features of the tumours. RESULTS In total, we obtained 33 samples from the primary site of tumours and 20 samples from lymph node metastases; in total, 27 cell lines were successfully isolated. Morphologic features characteristic of tumour cells in primary cell lines and epithelial differentiation (positive for AE1/AE3 cytokeratin) were evaluated. Higher tumour stage, angioinvasion and presence of perineural spread in primary tumour correlated positively with successful cell isolation from lymph node metastasis. All samples tested were NRAS wild-type. No correlation was found between molecular phenotype and the cell culture features. A higher proliferation potential was observed in the primary tumour cells, whereas higher sensitivity to irinotecan was found in the lymph node metastatic cells. CONCLUSIONS Using mechanical dissociation, we successfully derived and cultivated CRC cells from primary tumours and lymph node metastases with success rate 3 % and 70% respectively. Primary tumour features favouring successful establishment of cell cultures were identified.

Abstract
BACKGROUND Thrombocytosis is a common phenomenon in critically ill patients. Although thrombocytosis is an independent risk factor for complications, it does not seem to influence mortality in intensive care (ICU) patients. OBJECTIVES Our investigation aimed to evaluate the etiological and clinical relevance of a platelet count greater than 450 × 109/l in ICU patients. MATERIALS AND METHODS Patients admitted for a minimum of 4 days to an interdisciplinary ICU during a 45-month period were enrolled in this retrospective observational study. Thrombocytopenic patients (platelet count <150 × 109/l in at least one measurement) were excluded. The study patients were divided into two groups: thrombocytosis group (thrombocytes >450 × 109/l in at least one measurement) and control group (thrombocytes = 150 - 450 × 109/l during ICU stay). Univariate and multiple regression analysis were used to determine the influence of severe co-morbidities on the development of thrombocytosis and the association of elevated platelet count with thrombotic embolism, length of stay (LOS) in ICU, and mortality. RESULTS A total of 307 patients were analyzed, of whom thrombocytosis was observed in 119 cases. Independent risk factors for the development of thrombocytosis included SIRS, mechanical ventilation, and acute bleeding. Increasing age reduced the risk of thrombocytosis. Thromboembolism occurred in 16 patients (13.4%) with an elevated platelet count and only in nine patients (4.7%) with physiological platelet values (OR: 3.1; 95% CI: 1.3-7.2; p = 0.009). Mean duration of LOS was significantly longer in patients with thrombocytosis (25.2 vs.11.7 days, p < 0.0001). Elevated platelet count showed a negative correlation with ICU mortality (OR: 0.32; 95%-CI: 0.12-0.83; p = 0.019). CONCLUSION In our retrospective analysis the occurrence of thrombocytosis in a cohort of interdisciplinary ICU patients was associated with a higher rate of complications and longer LOS in the ICU. Despite these findings, thrombocytosis seems to reduce mortality in critical ill patients.

Abstract
The study is focused on drought stress that is detrimental to yield formation of field-grown vegetables in the lowland regions of the Czech Republic. Extensive vegetable yield losses are attributed to drought, often in combination with heat or other stresses. The objective of this research was to investigate, under field conditions, the effect of drought stress quantified by the Standardized Precipitation Evapotranspiration Index (SPEI) on yield variability of key vegetable crops growing in the Elbe River lowland, representing central European agriculture conditions. Additionally, we also tried to determine the period of crop with the highest sensitivity to drought (PCSD) of vegetable crops over the Elbe River lowland. Historical climate datasets for a regular gridded network with a high horizontal resolution of 10 km (CZGRIDS) and 305 climatological stations from the Czech Hydrometeorological Institute were applied. The SPEI at 1-, 3-, and 6-month lags was calculated for the period 1961-2014 based on precipitation and input dataset for the reference evapotranspiration (ETr) by the Penman-Monteith (PM) method. Moreover, the difference between daily precipitation and crop evapotranspiration (ETc) has been used to calculate the mean crop water balance (D) per main growth stages, as an indicator of plant stress. This improvement increased the applicability of the SPEI in agriculture drought impact on rainfed and/or irrigated field crops grown under various agronomic management systems. To understand how the SPEI, over the period 1989-2014, controlled the yield variation, we calculated the percentage of yield losses and gains for each crop. When the value of SPEI at 3-month lag–as a measure of the balance between the water availability and the atmospheric water demand–for PCSD was between -1.49 and 0.99, the yield moderately increased for Fruiting vegetables (e.g. tomatoes, cucumber). Conversely, when the SPEI-3 in the key development stage dropped below -3.0, the yield losses were about -30% and a negative influence is apparent from threshold of the SPEI≤-1.5. The effect of the SPEI on yield formation of vegetable cultivars grown under filed conditions was achieved up to 62% in the study region.

Abstract
Histiocytic necrotizing lymphadenitis / Kikuchi-Fujimoto disease (HNL/K-F) is being recognized with an increasing frequency not only in the East Asia but also on the American continents and in the Europe. Still the diagnostics of HNL/K-F is not easy and difficulties with its proper classification persist. In a group of 19 patients diagnosed primarily or as consults at our department there were 12 woman and 7 men. An average age at diagnosis was 28 years, median 25 years. Cervical lymph nodes were involved in 18 patients. Bilateral lymphadenopathy was present in one patient, the remaining 17 were unilateral. Inguinal lymph node was affected in one patient. In one other patient there were enlarged retroperitoneal lymph nodes simultaneously with a cervical lymphadenopathy. The size of the lymph nodes varied between 5 mm to 32 mm. The subclassification showed the necrotizing type in 14 patients, in one there was a predominant xanthomatous tissue reaction around the necrotic areas (xanthomatous type), and in 4 patients the disease was recognized as the proliferative type without necrosis (in two with a variously intense apoptosis of the proliferating lymphocytes). Of 10 consult cases the tumor was primarily evaluated as B cell lymphoma not otherwise specified (1x), peripheral T cell lymphoma (1x), classical Hodgkin lymphoma of mixed cellularity (1x); two patients were submitted with a differential diagnosis between peripheral T cell lymphoma and HNL/K-F; in one diagnosis of probable EBV lymphadenitis and in one diagnosis HNL/K-F was made. There were no data submitted in the remaining three cases. The authors stress diagnostic features which should lead to the diagnosis of the disease and should prevent unnecessary oncological staging investigations and potential chemotherapy for a lymphoma. Among diagnostic features of HNL/K-F identification of the proliferating cells - CD8 activated lymphocytes with apoptotic decay prevail, there are frequent plasmacytoid monocytes and a striking reaction of macrophages which are CD68/myeloperoxidase positive. There are virtually no neutrophil granulocytes and there is a miminal participation of plasma cells. In case of necrotizing and xanthomatous type infectious causes are to be ruled out as well. In case we still need to distinguish HNL/K-F from a lymphoma PCR analysis of a rearrangement of the immunoreceptor gene in T cell population should be investigated.

Abstract
The use of volatile anaesthetics in intensive care medicine has so far been limited by the lack of equipment suitable for daily routine use and the need for an anaesthetic machine. The new Anaesthetic Conserving Device (AnaConDa) enables the routine use of volatile anaesthetics for long-term sedation via intensive care ventilators. The Anaesthetic Conserving Device replaces the common heat and moisture exchanger in the ventilation circuit. The volatile anaesthetic is continuously applied in liquid status via a syringe pump to a form of mini-vaporiser where the anaesthetic agent is vaporised. The expired anaesthetic gas is stored in the carbon filter and approximately 90% of the gas is resupplied into the breathing cycle. The current experiences suggest that volatile anaesthetics present an alternative for long-term sedation in intensive care units, providing optimised pathways, from a medical as well as from an economical point of view. It must, however, be emphasized that the use of volatile anaesthetics for longer periods of time is an off-label use and should only undertaken by medical professionals at their own risk.

Abstract
BACKGROUND The purpose of the present experimental study was to determine the feasibility and usefulness of brain temperature measurement (T(br)) and the calculated difference between brain temperature and arterial blood temperature (DeltaT(br-a)) in uninjured brain during variations of cerebral perfusion pressure (CPP) and concomitant changes of the regional cerebral blood flow (rCBF). METHODS Nine anaesthetized pigs were subjected to controlled CPP decrease to assess the lower cerebral autoregulation threshold. A parenchymal intracranial pressure (ICP) sensor combined with a microthermistor for temperature measurement, a miniaturized Clark-type electrode measuring brain tissue oxygenation (p(ti)O(2)), a small flexible intraparenchymal thermodilution probe for measuring rCBF and cerebral microdialysis were inserted carefully in the frontal white matter. RESULTS Analysing the p(ti)O(2) during controlled CPP decrease, we found significant breakpoints of p(ti)O(2) at a CPP of 40 mmHg and 20 mmHg, related to an rCBF of 20 ml/100 g/min and approximately 10 ml/100 g/min. Similarly, the relationship between DeltaT(br-a), and CPP or rCBF revealed a characteristic increase of DeltaT(br-a) in the negative direction up to more than -0.30 degrees C assuming a strong flow dependency. CONCLUSION The temperature difference between brain tissue and arterial blood DeltaT(br-a) mainly reflects the cerebral blood flow-brain tissue oxygenation-metabolism relationship as far as the estimation of the individual lower cerebral autoregulation threshold.

Abstract
Microbial blood infection represents a high risk for immuno-suppressed patients. Of all catheter-related infections in the bloodstream, 90% result from the use of central venous catheters, the main cause being microbial colonization at the catheter's insertion point or the catheter hub. Between January 2003 and December 2004, 102 patients received a renal transplant including 57 who received a triple-lumen central venous catheter (CVC) during the procedure. Two catheters were used: a standard polyurethane catheter placed in the jugular veina or the subclavian veina for group I, and polyurethane catheters with the AgION antimicrobial system always placed in the subclavian veina for group II. Care and maintenance of the CVCs was standardized in both groups. After catheter removal, the tips were analyzed microbiologically. Of 57 (43.9%) CVCs, 25 were found to be contaminated. In the first group 24 out of 41 CVCs (58.5%) showed bacterial growth, whereas in group II only one catheter (6.6%) had a biofilm. The most common contaminant (18 out of 25, 72%) was Staphylococcus epidermidis. In group II, two patients had positive blood cultures yet a microbiologically sterile CVC. None of the catheters with the AgION antimicrobial system had to be removed owing to local infection or intolerance. The continuous release of silver ions increases the protection against bacteria and fungi during the entire time of catheterization. Use of catheters with the AgION antimicrobial system lead to a marked reduction in catheter-associated infections of the bloodstream.

Abstract
Using a well defined pig model, we investigated whether cerebral hypertension and hypotension influence hemorheological factors. After surgical preparation and stabilization, periods of hyperventilation, controlled periods of cerebral perfusion pressure increases and decreases were utilized. After each period, blood samples were collected from the cannulated femoral artery and vein, and from the superior sagittal sinus. Erythrocyte deformability, whole blood and plasma viscosity and hematological parameters were determined. Erythrocyte deformability significantly worsened in arterial samples after hypertension and hypotension, and in sinus samples it was impaired after hypotension period. Hematocrit significantly increased in arterial and sinus samples during hypertensive period, accompanied by similar alterations in whole blood viscosity. We conclude that hemodynamic changes caused by hyperventilation, hyper- or hypotension can influence hemorheological factors, and suggest that the rheological alterations can affect local hemodynamic and metabolic conditions.

Abstract
BACKGROUND Diagnostic approach to non-Hodgkin's lymphomas requires a combination of laboratory methods. Methods used in morphology constitute the basis of the diagnostics; in many instances it is necessary to combine them with methods of molecular genetics. The latter method plays a key role in the detection of B cell clonality using identification of the rearrangement of IGH and/or IGK genes and in detection of the chromosomal translocations specific for some lymphomas. METHODS AND RESULTS Using PCR we investigated 113 patients with malignant B cell lymphomas of different types (follicular--FL, mantle cell--MCL, small cell--CLL/SLL, diffuse large cell--DLBCL). We established the IGH gene clonal rearrangement in 85% of the cases (96/113), and the clonal rearrangement of the IGK gene in 58.3% patients (42/72). Combination of both approaches (IGH and IGK) revealed a positive result in 90.3% (102/113). The highest yield was rendered in patients with CLL/SLL and with MCL (100%), and it was 86 and 87% in cases with FL and DLBCL. CONCLUSIONS The detection of clonality in lymphomas helps to distinguish a malignant disease from polyclonal hyperplastic and lymphoproliferative disorders of B cells. The recognition of clonal rearrangements of the IGH and IGK genes serves for a long term monitoring of the disease activity in cases in which there are no other molecular markers available. The demonstration of lymphoma characteristic translocations is relatively specific and useful but at present its usefulness is reduced in cases with variable breakpoint regions.

Abstract
Molecular methods play an important role in diagnostic pathology of lymphomas. PCR based demonstration of clonality or detection of a specific chromosomal translocation may determine the exact classification of the lymphoma. Hence the final diagnosis may depend on the quality of preserved nucleic acids in the bioptic specimen. The integrity of DNA and RNA may be damaged by formalin fixation, which destroys the nucleic acids by fragmentation. Therefore, a portion of each lymphoma sample should be frozen. To substitute freezing techniques we utilized ethanol as a fixative, which preserves nucleic acids. We compared PCR and RT-PCR products from lymphoma samples, which were differently pre-treated by ethanol fixation, formalin fixation and freezing. The ethanol fixed samples retained a high quality of both DNA and RNA and provided reproducible PCR products similar to frozen samples and significantly better then those extracted from formalin fixed samples. We may recommend ethanol as a complementary fixative for all pathology laboratories where deep freezing in not routinely available.

Abstract
The differential-diagnostic strategy and the order of precedence of most diverse radiologic diagnostic procedures are discussed based on a case of retroperitoneal bleeding. Apart from iatrogen-caused bleedings, the therapeutic anticoagulant therapy in the context of the patient's disease, haemodialysis or a rare, spontaneously-occurring retroperitoneal bleeding play a substantial role. In the order of precedence of radiologic diagnostic procedures for fast diagnosis of a retroperitoneal haematoma, the abdomen CT-scan is the preferred method.

Abstract
Diagnosis of follicular lymphoma (FL) is based on histology and immunohistochemical profile (CD20+, CD79alfa+, CD10+, BCL-2+, CD5-). A chromosomal marker--translocation t(14;18)(q32;q21) supporting the tumor diagnosis and useful for monitoring bone marrow or peripheral blood infiltration by the tumor cells is also used. The BCL2 gene (18q21) is controlled by an enhancer of the IGH gene (14q32) resulting in BCL-2 protein overexpression. The translocation is present in the majority of patients with FL. The aim of the study was to introduce the quantitative PCR (RQ-PCR, real-time quantification) method for the assessment of the quantity of cells bearing the translocation t(14;18) in patients with FL. The fluorescence in situ hybridization on interphasic nuclei (I-FISH) in histologic sections was used for screening of patients with the t(14;18). A search for the break of the BCL2 gene at the major breakpoint region (mbr) was performed by means of qualitative PCR. We determined the relative number of the tumor cells bearing t(14;18) translocation (mbr) in patients with FL by the RQ-PCR. The relative quantity of these cells was significantly higher in the lymph nodes than in the bone marrow or peripheral blood. The RQ-PCR is a tool of choice to monitor the activity of the disease in individual patients, and to detect an early disease relapse before its manifestation at the level diagnosed by morphology.

Abstract
BACKGROUND Diffuse large B-cell lymphomas represent a heterogeneous group of tumors with a different origin, morphological findings and a variable clinical prognosis. These tumors have been recently classified into two prognostically relevant subgroups differing in the gene expression. The key genes suitable for routine diagnostics of DLBCL have not been yet identified. The aim of this work was to study changes and expression of several genes and proteins participating in the genesis of DLBCL. METHODS AND RESULTS We analysed a group of 31 patients with diffuse large B-cell lymphomas. Basic clinical data including follow-up of the patients were available. Tumors were examined by a panel of immunohistochemical reactions with antibodies against CD20, CD79a, BCL-2, BCL-6, CD10, Ki-67 and TP53. FISH was used to detect a translocation t(14;18)(q32;q21) and/or a break in BCL6 region (3q27) suggestive of a translocation with a variable translocation partner t(3;?). PCR was utilized to detect the translocation t(14;18) and a clonal rearrangement of heavy and/or kappa chain of the immunoglobin genes. CONCLUSIONS The expression of BCL-2 protein appeared to correlate with a higher mortality rate. The expression of other proteins examined in the study did not correspond significantly with the clinical development of the disease. Tumors with follicular lymphoma as a component had significantly higher mortality rate than the tumors developing de novo. Moreover, higher mortality was evident in cases with higher values of the International Prognostic Index (IPI).

Abstract
Brain tissue oxygen monitoring (P(ti)O2 (Neurotrend, Codman, Germany) was employed in addition to standard intracranial pressure (ICP) and cerebral perfusion pressure (CPP) monitoring in seven patients with severe neuronal damage of heterogeneous etiology. The correlation between P(ti)O2 changes and CPP fluctuations during periods of 30 minutes were analyzed, when CPP was above 70 mmHg and lower than 100 mmHg. A new ratio, the CPP-oxygen-reactivity (COR) index was calculated as COR=delta p(ti)O2 %/delta CPP%. The patient COR values were compared to those found in the brain of six noninjured anesthetized piglets. The analysis was performed to determine the significance of synchronous fluctuations of CPP and P(ti)O2, when CPP is above the lower threshold of autoregulation. The correlation between CPP variations and p(ti)O2 variations was found to be strong (R(mean)) = 0.74 +/- 0.17) in the patients and was weak in the uninjured animals (R(mean)) =0.38 +/- 0.43). The COR (mean) was 2.05 +/- 0.57 in patients and 0.78 +/- 0.6 in the animals. In the injured brain of our patients, we observed an unexpectedly close correlation between P(ti)O2 and CPP variations when CPP levels were within a therapeutically targeted range (70 to 100 mmHg). In a porcine model, we could not find this relationship in the noninjured brain. We speculate that an increased COR might be indicative for an impaired local pressure autoregulation. The preliminary data suggest that COR values above "1" might be pathologic. However, the reported sample sizes are too small to provide sufficient statistical power to justify inferential statistical analyses. As such, results are presented with descriptive statistics only, and should be regarded as a hypothesis.

Abstract
Herpes simplex infections are potentially a life-threatening situation for immunocompromised as well as critically ill patients. The correct diagnosis is made more difficult in comatose patients by the fact that the characteristic symptom of extreme pain cannot be registered. The clinical dermatological findings (polycyclic configuration, easily bleeding ulcers) are thus especially important in patients under intensive care conditions. As examples, the cases of 3 critically ill patients (subarachnoid bleeding or head injury) developing therapy-resistant, flat sacral or perioral skin ulcers with peripheral blisters are presented. Herpes simplex virus was confirmed immunohistologically and in the smear test. All patients subsequently died. These cases emphasize that patients in the intensive care unit are in danger of developing a chronic persistent Herpes simplex infection due to latent immunosuppression. Chronic persistent Herpes infections may be underrated in intensive therapy, and must always be ruled out in case of therapy-resistant erosions or ulcerations.

Abstract
The authors analyze on a case-history the problem of lymphomas of the gastrointestinal tract. The patient was a female who was operated on account of a suspected perforation. On operation multiple perforations of the small intestine were found. A resection was performed. According to the histological results it was a giant-cell B-lymphoma of the small intestine. The postoperative course was without major complications. The patient was referred to the oncological department without further treatment.

Abstract
The parity-violating longitudinal analyzing power, A(z), has been measured in pvectorp elastic scattering at an incident proton energy of 221 MeV. The result obtained is A(z) = [0.84+/-0.29(stat)+/-0.17(syst)]x10(-7). This experiment is unique in that it selects a single parity violating transition amplitude (3P2 - 1D2) and consequently directly constrains the weak meson-nucleon coupling constant h(pp)(rho). When this result is taken together with the existing pvectorp parity violation data, the weak meson-nucleon coupling constants h(pp)(rho) and h(pp)(omega) can, for the first time, both be determined.

Abstract
We report a unique case of aleukemic granulocytic sarcoma of the neck, originally misdiagnosed as non-Hodgkin's lymphoma (NHL), though chloroma was also suspected due to a greenish macroscopic appearance and the presence of myeloid chloroacetate esterase (CAE)+ cells. The proof of clonal T cell receptor gamma chain (TcRgamma) gene rearrangements in the recurring tumor was deemed to confirm the initial diagnosis of T cell NHL. Altogether five distinct types of clonal TcRgamma gene rearrangements were found in the tumor, bone marrow and peripheral blood. Only retrospectively, using RT-PCR, did we detect the acute myeloid leukemia subset-specific fusion gene AML1/ETO in the frozen samples of the relapsed tumor, as well as in the otherwise unaffected bone marrow and peripheral blood (representing 'minimal initial disease' in the latter two samples). Simultaneous staining verified that the neoplastic CAE+ cells and CD45RO+ T cells were different populations.

Abstract
UNLABELLED Brain tissue oximetry (ptiO2) using flexible micro-polarographic electrodes is a loco-regional approach to monitor oxygen supply to the injured brain, after neuronal damage. In patients after severe head injury (SHI), disturbances of CBF and CO2 related vasoconstriction have been demonstrated. CO2 reactivity testing may assist to determine outcome in these patients. Not much information is available on the preservation of vasoreactivity to arterial hyperoxia after neuronal damage. Therefore, we studied the response of ptiO2 in 7 piglets and in 14 patients on day one after trauma to 100% FiO2 ventilation (O2rea) and analyzed the 3 month outcome using the Glasgow-Outcome-Score (GOS). In the animal study, we placed a Paratrend 7 (P7) sensor for ptiO2 measurements in the non injured frontal white matter. The animals were anesthetized and mechanically ventilated. FiO2 was increased from 30 (+/- 5)% to 100% over a period of 5 minutes. In patients, we placed the P7 probe in the frontal lobe. FiO2 was increased from 35 (+/- 5)% to 100% over a period of 6 hours. O2rea was tested by calculating the percentage change of ptiO2 during 100% FiO2 ventilation, compared to the baseline value of 35% FiO2. By analyzing the patient outcome, we were able to define two patient populations according to the GOS at three month (Group I: favorable outcome [GOS 0-2]; Group II: poor outcome [GOS 3-4]). For the non-injured brain tissue in animals were revealed an O2rea = 0.21 (+/- 0.12). PATIENTS Group I: O2rea = 0.4 (+/- 0.16); Group II: 0.9 (+/- 0.6). Group I and II were statistical significant different (p < 0.05; unpaired t-test). Oxygen reactivity in severely head patients is a simple test with prognostic value using ptiO2 measurement. These results may be explained by the close relationship of CBF disturbances to oxygen vasoreactivity after traumatic brain injury. The O2rea in animals without neuronal damage is smaller than in patients after SHI. We speculate, the animal data could be considered as normal value of O2rea in non injured brain tissue.

Abstract
Management of critically ill patients requires frequent arterial blood gas analyses for assessing the pulmonary situation and adjusting ventilator settings and circulatory therapeutic measures. Continuous arterial blood gas analysis is a real-time monitoring tool, which reliably detects the onset of adverse pulmonary effects. It gives rapid confirmation of ventilator setting changes and resuscitation and helps to ensure precise adjustment of therapy. In this study a newly available fiber optic sensor system has been employed for continuous intraarterial blood gas monitoring. The measurement performance was compared with a bench top blood gas analyzer. A prospective study was performed enrolling 20 patients undergoing surgery. A comparison between intermittent blood gas analyses (ABL Radiometer 610) and the results of continuous blood gas monitoring (Paratrend 7+, Agilent Technol.) was performed by simultaneous measurements. Statistical analysis in agreement with the method of "Bland and Altman" was employed. Two case reports are provided of patients with Acute Adult Respiratory Distress Syndrome and rapid changes in ventilator settings. Over a range of arterial oxygenation from 10 to 50 kPa the bias for pO2-measurement was 0.2 (limits of agreement 4), R2 = 0.9. If the arterial pO2 was higher than 50 kPa the bias was -7 (10) kPa. PCO2-measurement showed a bias of 0.25 (limits of agreement 0.45), R2 = 0.7. pH bias was -0.02 (limits of agreement 0.04), R2 = 0.7. The Paratrend 7+ sensor proved to be clinical feasible and showed an improved precision in terms of clinical situations with an arterial pO2 smaller than 50 kPa. However, the results are not much different regarding the findings with older systems consisting of hybrid technology combining optodes and electrochemical oxygen measurement. The advantages might be seen if the sensor is used for a period over several days in patients on ICU as demonstrated by the two case reports.

Abstract
PURPOSE To examine nurse-patient communication about preferences for cardiopulmonary resuscitation (CPR). DESIGN Prospective cohort. Sampled were patients and nurses caring for patients enrolled in SUPPORT (1989-91), a multicenter study of seriously-ill hospitalized adults at four U.S. hospitals. METHODS Information about patient preferences was obtained by interviews with patients and their designated surrogates. For selected patients, nurses were interviewed prospectively about their understanding of patients' preferences and whether they discussed these preferences with their patients. Nurse demographic information was obtained by questionnaire. Additional patient data were obtained by interview and chart review. Logistic regression was used to identify independent correlates of nurse-patient communication and nurses' understanding of patients' preferences. FINDINGS For 1,763 study patients, 1,427 nurse interviews (response rate 81%) were obtained. The median age of interviewed nurses was 29 years; 96% were women, 68% had a bachelor's or master's degree, and 62% had worked for 5 years or more as a nurse. Nurses reported discussions about CPR with 13% of their patients, and these discussions were more likely if the nurse thought the patient did not want CPR (adjusted odds ratio [AOR] 2.68; 95% CI 1.84 to 3.90), if the nurse had spent more time with the patient (AOR 1.05; 95% CI 1.02 to 1.08) per 5 additional days, if the patient had metastatic cancer (AOR 3.56; 95% CI 1.86 to 6.78), or if the patient was in an intensive care unit at the time of study entry (AOR 2.08; 95% CI 1.26 to 3.42). Diagnosis and study site were also associated with nurses' reports of discussions with patients. Of 551 patients with available data, 58% (n = 317) wanted CPR and 30% (n = 164) did not. Nurses understood patients' CPR preferences correctly for 74% of the patients. Nurses were more likely to understand patients' preferences to forego CPR if the patient was 75 years of age or older (AOR 6.6; 95% CI 2.0 to 22.0) or if the nurse and patient had discussed the patient's preferences (AOR 25.3; 95% CI 6.5 to 98.6) or if the patient had cancer (AOR 10.9; 95% CI 2.3 to 50.1). Nurses' understanding of patients' preferences for CPR was no better than that of physicians or patients' surrogate decision-makers. CONCLUSIONS In this sample of seriously ill hospitalized adults, discussions between patients and nurses about CPR were infrequent. Nurses' understanding of patients' preferences for care was similar to that of physicians and patients' surrogate decision-makers. Educational interventions should focus on increasing the frequency of nurse-patient discussions about end-of-life care and improving nurses' understanding of patients' preferences for care.
