BACKGROUND: The evaluation of DWI/FLAIR mismatch in ischaemic stroke patients with unknown, time from onset can determine the treatment strategy. This approach is based on, visual assessment and may be subject to insufficient inter-rater agreement. OBJECTIVE: To compare the inter-rater agreement of visual evaluation of FLAIR MRI and proposed region of interest (ROI) semiquantitative method in large vessel occlusion (LVO) strokes. METHODS: Five readers have analysed MRIs of 104 patients obtained within six hours of the onset of stroke symptoms resulting from LVO visually and semi-quantitatively. For the semiquantitative analysis, a ROI method was used to obtain relative signal intensity compared to the unaffected side. Cut-off values of 1.15 and 1.10 were tested. The analysis yielded FLAIR-positive (abnormal) and negative (normal) findings. Percentage agreement and Fleiss kappa coefficients were calculated. RESULTS: The visual agreement of 5/5 readers and ≥ 4/5 readers occurred in 31% and 59% of cases respectively. Semi-quantitative evaluation using a cut-off value of 1.15 increased the agreements to 67% and 88% respectively. The agreement of visual evaluation was fair. The semi-quantitative method utilising the cut-off of 1.15 had moderate agreement although it increased the number of FLAIR-negative results compared to the visual evaluation. A low cut-off value of 1.10 didn't improve the agreement significantly. CONCLUSION: The inter-rater agreement of visual evaluation of FLAIR in patients with short-duration large vessel occlusion stroke was fair. The high cut-off value of semiquantitative evaluation increased the agreement although it changed the proportion of FLAIR positive and negative results.

INTRODUCTION: The indications for popliteal artery aneurysm treatment are clear. In aneurysms with patent inflow and outflow arteries, the risk of peripheral embolisation from a mural thrombus is high and the treatment, mostly a vascular intervention, is focused on preventing this extremity-threatening complication. It is unclear, however, how high the risk of peripheral embolisation is and how to proceed with a patent popliteal artery aneurysm fed by the deep femoral artery when the superficial femoral artery is chronically occluded. METHODS: All patients diagnosed with popliteal artery aneurysm between 2015 and 2019 were searched in the database of the Department of Surgery II of University Hospital Olomouc. Patients with a patent popliteal artery aneurysm and chronic superficial femoral artery occlusion in the ipsilateral extremity were selected. RESULTS: We diagnosed 66 patients with 85 popliteal artery aneurysms. Four patients had a patent popliteal artery aneurysm and chronic superficial femoral artery occlusion in the ipsilateral extremity. In these patients, conservative treatment was indicated after the diagnosis was determined. In three patients, no clinically obvious complication of the popliteal artery aneurysm occurred. In one patient, popliteal artery aneurysm thrombosis occurred after a follow-up of 21 months, leading to a shortening of his calf claudication distance and limiting the patient. CONCLUSION: Our experience with this small group of patients shows the possibility of primary conservative treatment in patients with a patent popliteal artery aneurysm below the chronic superficial femoral artery occlusion site. Aneurysm thrombosis can be expected during follow-up. Patients in whom the thrombosis leads to limitations are indicated for surgical intervention. The risk of peripheral embolisation from the mural thrombus cannot be excluded with certainty. Further studies involving large groups of patients are needed to provide a more precise recommendation.

Differential expression of HLA-DQA1 and HLA-DQB1 gene alleles was analysed in three different cell populations isolated from peripheral blood-B lymphocytes, monocytes and whole-blood cells. Interallelic differences in mRNA levels were observed: DQA1*03 alleles were among the most expressed in all cell types, whereas DQA1*05 alleles were least expressed in whole blood and monocytes and among the most expressed in B cells. For DQB1 gene, DQB1*06 group of alleles were the most expressed, and DQB1*02 group the least expressed within all cell populations examined. In comparison with the rest alleles, DQB1*06 and DQB1*05:02 alleles have higher expression in monocytes than in B cells, professional antigen-presenting cells. Cell type-specific regulation of expression was observed as well, with higher and more balanced expression of alleles in B lymphocytes compared to monocytes.

INTRODUCTION: Primary colonic lymphoma is a very rare malignant disease of the gastrointestinal tract, accounting for 14% of all malignant diseases in this location. It is classified in the group of extranodal lymphomas; its long-term asymptomatic progression makes it different from common colorectal carcinomas making its diagnosis very difficult, more often accidental. Gallstone ileus is quite an uncommon complication of cholecystolithiasis diagnosed with difficulty. Up to 50% of cases are diagnosed during surgery. The obturated location depends on the size of the stone, location of the conjunction between the biliary and gastrointestinal tracts, and also on any preexisting stenosis due to another unknown pathology. CASE REPORT: We present a case of an 86-year-old man treated for acute diverticulitis with typical clinical symptoms. Following further examination (colonoscopy, computed tomography) revealed a tumour-like infiltration in the sigmoid colon wall and a voluminous polyp was suspected according to the colonoscopy. Computed tomography described an obstruction by a biliary stone tumbling through the cholecystocolonic fistula. Subsequent biopsy supported the suspected malignant etiology. The patient underwent resection of the sigmoid colon sec. Hartmann; an infiltration was found in the subhepatic space, which corresponded to the described fistulisation between the biliary tract and the colon. A large 40 mm gallstone was found in the resected sigmoid colon over the stenosis and the bowel wall showed diffuse thickening with several polyps; final histopathological assessment confirmed malignant lymphoma of the plasmocytoma type. No serious complications occurred in the postoperative period; after healing, the patient was transferred to hematooncology care. CONCLUSION: The article describes the presence of two rare diseases - colonic lymphoma and gallstone ileus. Clearly, without the biliary stone obstruction in the preexisting tumorous stenosis in the sigmoid colon, the malignant hematooncology disease would not have been diagnosed. KEY WORDS: primary colonic lymphoma - gallstone ileus - complication of the cholecystolithiasis - extranodal lymphoma - acute diverticulitis.

INTRODUCTION: Postpancreatectomy haemorrhage (PPH) is considered to be the most severe specific postoperative complication following pancreatic resections and its treatment is difficult and requires coordinated interdisciplinary collaboration. PPH causes 11-38% of all post-pancreatectomy deaths. The aim of this study was to determine the prevalence of PPH in a set of patients operated on within the last 10 years, and to analyze the diagnostic methods, treatment modalities and the outcomes. METHODS: A retrospective analysis of patients undergoing pancreatic resections between 2006 and 2015. Clinically relevant PPH (types B and C) were the subject of interest. The onset, location and severity of PPH were analysed. Other factors analysed included operation diagnosis of PPH, diagnostic methods along with signs of sentinel bleeding, treatment options undertaken including the number of transfusions. 30-day, 90-day and in-hospital mortality, as well as the length of hospital stay and readmission rate were calculated. A descriptive statistical method was used. RESULTS: A total of 449 patients were operated on. Pancreatoduodenectomy (DPE) or pylorus-preserving pancreatoduodenectomy (PPPD) was done in 76.4%, left sided pancreatectomy (LPE) in 19.8% and total pancreatectomy (TPE) in 3.8%. 190 of the patients (42.3%) were women and 259 (57.7%) men, with the mean age of 61.5±11.1 years. A total of 23 (5.1%) PPH cases were identified, 21 (4.7%) were clinically relevant. Eight patients (35%) developed early PPH with direct reoperation, late PPH was seen in 14 patients after DPE and in one after LPE. Sentinel bleeding was present in 53.3% of late PPH cases. CT/CTA was performed in four patients with subsequent DSA performed in three. DSA identified a gastroduodenal artery stump pseudoaneurysm in one patient, which was resolved using a stent. Surgical intervention for late PPH was required in 10 patients in total, six of whom needed direct surgery due to the rapid development of circulatory instability and 3 due to inconclusive radiological management. One patient needed surgical drainage of both an abscess and haematoma. In two patients the origin of bleeding was due to a gastric ulcer, which was proven and solved endoscopically and 2 patients required conservative treatment only. The specific mortality for PPH was 17.4%. In the group of patients that suffered with any PPH following DPE and PPDPE the mortality rate was 22.2%, and 28.6% for late PPH. If late PPH developed coincidentally with postoperative pancreatic fistula (POPF), the mortality was 44%. In the early PPH group, an average of 10.1±2.5 transfusion units (TUs) were used with an average length of hospital stay 17.5±4.8 days and zero mortality in comparison to an average of 11.7±10 TUs and 29.9±14.6 days in hospital and 26.6% mortality in the late PPH group. CONCLUSION: PPH is a severe complication, which has a high mortality rate. It also often coincidentally develops with POPFs. Early clinical diagnosis with identification of its cause plays a key role in management. The use of interventional radiology in the treatment of PPH has begun to dominate other treatment modalities due to a very high success rate, and close collaboration with interventional radiologists is necessary in order to reduce the rate of surgical intervention required in PPH. KEY WORDS: haemorrhage - pancreas - resection - complications - mortality.

Susceptibility to environmental stressors has been described for fetal and early childhood development. However, the possible susceptibility of the prepubertal period, characterized by the orchestration of the organism towards sexual maturation and adulthood has been poorly investigated and exposure data are scarce. In the current study levels of cadmium (Cd), cotinine and creatinine in urine were analyzed in a subsample 216 children from 12 European countries within the DEMOCOPHES project. The children were divided into six age-sex groups: boys (6-8 years, 9-10 years and 11 years old), and girls (6-7 years, 8-9 years, 10-11 years). The number of subjects per group was between 23 and 53. The cut off values were set at 0.1 µg/L for Cd, and 0.8 µg/L for cotinine defined according to the highest limit of quantification. The levels of Cd and cotinine were adjusted for creatinine level. In the total subsample group, the median level of Cd was 0.180 µg/L (range 0.10-0.69 µg/L), and for cotinine the median wet weight value was 1.50 µg/L (range 0.80-39.91 µg/L). There was no significant difference in creatinine and cotinine levels between genders and age groups. There was a significant correlation between levels of cadmium and creatinine in all children of both genders. This shows that even at such low levels the possible effect of cadmium on kidney function was present and measurable. An increase in Cd levels was evident with age. Cadmium levels were significantly different between 6-7 year old girls, 11 year old boys and 10-11 year old girls. As there was a balanced distribution in the number of subjects from countries included in the study, bias due to data clustering was not probable. The impact of low Cd levels on kidney function and gender differences in Cd levels needs further investigation.

In 2004 the European Commission and Member States initiated activities towards a harmonized approach for Human Biomonitoring surveys throughout Europe. The main objective was to sustain environmental health policy by building a coherent and sustainable framework and by increasing the comparability of data across countries. A pilot study to test common guidelines for setting up surveys was considered a key step in this process. Through a bottom-up approach that included all stakeholders, a joint study protocol was elaborated. From September 2011 till February 2012, 17 European countries collected data from 1844 mother-child pairs in the frame of DEMOnstration of a study to COordinate and Perform Human Biomonitoring on a European Scale (DEMOCOPHES).(1) Mercury in hair and urinary cadmium and cotinine were selected as biomarkers of exposure covered by sufficient analytical experience. Phthalate metabolites and Bisphenol A in urine were added to take into account increasing public and political awareness for emerging types of contaminants and to test less advanced markers/markers covered by less analytical experience. Extensive efforts towards chemo-analytical comparability were included. The pilot study showed that common approaches can be found in a context of considerable differences with respect to experience and expertize, socio-cultural background, economic situation and national priorities. It also evidenced that comparable Human Biomonitoring results can be obtained in such context. A European network was built, exchanging information, expertize and experiences, and providing training on all aspects of a survey. A key challenge was finding the right balance between a rigid structure allowing maximal comparability and a flexible approach increasing feasibility and capacity building. Next steps in European harmonization in Human Biomonitoring surveys include the establishment of a joint process for prioritization of substances to cover and biomarkers to develop, linking biomonitoring surveys with health examination surveys and with research, and coping with the diverse implementations of EU regulations and international guidelines with respect to ethics and privacy.

In 2011 and 2012, the COPHES/DEMOCOPHES twin projects performed the first ever harmonized human biomonitoring survey in 17 European countries. In more than 1800 mother-child pairs, individual lifestyle data were collected and cadmium, cotinine and certain phthalate metabolites were measured in urine. Total mercury was determined in hair samples. While the main goal of the COPHES/DEMOCOPHES twin projects was to develop and test harmonized protocols and procedures, the goal of the current paper is to investigate whether the observed differences in biomarker values among the countries implementing DEMOCOPHES can be interpreted using information from external databases on environmental quality and lifestyle. In general, 13 countries having implemented DEMOCOPHES provided high-quality data from external sources that were relevant for interpretation purposes. However, some data were not available for reporting or were not in line with predefined specifications. Therefore, only part of the external information could be included in the statistical analyses. Nonetheless, there was a highly significant correlation between national levels of fish consumption and mercury in hair, the strength of antismoking legislation was significantly related to urinary cotinine levels, and we were able to show indications that also urinary cadmium levels were associated with environmental quality and food quality. These results again show the potential of biomonitoring data to provide added value for (the evaluation of) evidence-informed policy making.

INTRODUCTION: In general, pain in the lower right abdomen is the most frequent reason for hospital surgical admissions, acute appendicitis representing the most common cause of operation for acute abdomen. Timely appendectomy remains the only treatment in the early stages of inflammation and is usually uncomplicated, requiring only a short hospital stay. A differential diagnostic analysis necessitates a search for other, particularly long-term symptoms that might be driven to the background in cases of acute exacerbation. CASE REPORT: The case report presents a 38-year-old female patient who was admitted for lower right abdominal pain. Clinical examination and a blood test both suggested typical acute uncomplicated appendicitis, and therefore the patient underwent appendectomy. Haemorrhagic peritoneal fluid and nodularity of the appendix not typical for appendicitis was found. Oedema of the terminal ileum and a right adnexal tumour were a surprising finding. A more extensive surgical procedure involving ileocaecal resection and right-side adnexectomy was finally performed with regard to the intraoperative finding. The definitive diagnosis of appendiceal endometriosis, endometrial mass in the terminal intestine and ovarian endometriosis was established by histological evaluation. Long-term follow-up revealed microadenocarcinoma of cervix uteri. CONCLUSION: It is generally very difficult to confirm appendiceal endometriosis before operation, and revealing primary appendiceal endometriosis is virtually impossible. It is advisable to consider endometriosis in fertile women with chronic abdominal pain of unclear aetiology and gynaecological symptoms in their personal history. The best diagnostic and therapeutic method, respectively, is laparoscopy enabling exploration of the entire peritoneal cavity including the minor pelvis, and performing appendectomy as well as excision of suspicious endometrial lesions. The definitive diagnosis is usually established by histopathological evaluation. Gynaecological assessment and follow-up is highly recommended after surgery.
