Abstract
Lymph node status is one of the most important prognostic factors in colorectal cancer, and accurate pathological nodal staging and detection of lymph node metastases is crucial for determination of post-operative management. Current guidelines, including the TNM staging system and European Society for Medical Oncology (ESMO) guidelines, recommend examination of at least 12 lymph nodes. However, identification of an adequate number of lymph nodes can be challenging, especially in the setting of neoadjuvant treatment, which may reduce nodal size. In this study, we investigated 384 colorectal cancer resections that were processed at our department of pathology between January 2012 and December 2022, in which the number of detected lymph nodes was less than 12 subsequent to conventional preparation of mesocolic fat tissue. By means of acetone compression, lymph node harvest increased significantly (p < 0.0001), and the intended number of ≥ 12 lymph nodes was achieved in 98% of resection specimens. The number of nodal positive cases increased significantly from n = 95 (24.7%) before versus n = 131 (34.1%) after acetone compression due to additionally identified lymph node metastases (p < 0.001). In 36 patients (9.4%) initially considered as nodal negative, acetone compression led to a staging adjustment to a nodal positive category and thereby drove a recommendation to offer post-operative therapy. In conclusion, acetone compression is a reliable and useful method implementable in routine surgical pathology for the retrieval of lymph nodes in colorectal cancer specimen, allowing for an adequate lymph node sampling and an increase in nodal staging reliability.

Abstract
BACKGROUND Healthcare cannot achieve net-zero carbon without addressing operating theatres. The aim of this study was to prioritize feasible interventions to reduce the environmental impact of operating theatres. METHODS This study adopted a four-phase Delphi consensus co-prioritization methodology. In phase 1, a systematic review of published interventions and global consultation of perioperative healthcare professionals were used to longlist interventions. In phase 2, iterative thematic analysis consolidated comparable interventions into a shortlist. In phase 3, the shortlist was co-prioritized based on patient and clinician views on acceptability, feasibility, and safety. In phase 4, ranked lists of interventions were presented by their relevance to high-income countries and low-middle-income countries. RESULTS In phase 1, 43 interventions were identified, which had low uptake in practice according to 3042 professionals globally. In phase 2, a shortlist of 15 intervention domains was generated. In phase 3, interventions were deemed acceptable for more than 90 per cent of patients except for reducing general anaesthesia (84 per cent) and re-sterilization of 'single-use' consumables (86 per cent). In phase 4, the top three shortlisted interventions for high-income countries were: introducing recycling; reducing use of anaesthetic gases; and appropriate clinical waste processing. In phase 4, the top three shortlisted interventions for low-middle-income countries were: introducing reusable surgical devices; reducing use of consumables; and reducing the use of general anaesthesia. CONCLUSION This is a step toward environmentally sustainable operating environments with actionable interventions applicable to both high- and low-middle-income countries.

Abstract
Obesity (BMI ≥ 30 kg/m2) with related comorbidities such as type 2 diabetes mellitus, cardiovascular disease, sleep apnea syndrome, and fatty liver disease is one of the most common preventable risk factors for cancer development worldwide. They are responsible for at least 40% of all newly diagnosed cancers, including colon, ovarian, uterine, breast, pancreatic, and esophageal cancer. Although various efforts are being made to reduce the incidence of obesity, its prevalence continues to spread in the Western world. Weight loss therapies such as lifestyle change, diets, drug therapies (GLP-1-receptor agonists) as well as bariatric and metabolic surgery are associated with an overall risk reduction of cancer. Therefore, these strategies should always be essential in therapeutical concepts in obese patients. This review discusses pre- and post-interventional aspects of bariatric and metabolic surgery and its potential benefit on cancer development in obese patients.

Abstract
Magnetic Resonance Imaging (MRI) is routinely used for preoperative tumor staging and to assess response to therapy in rectal cancer patients. The aim of this study was to evaluate the accuracy of MRI based restaging after neoadjuvant CRT in predicting pathologic response. This multicenter cohort study included adult patients with histologically confirmed locally advanced rectal adenocarcinoma treated with neoadjuvant CRT followed by curative intent elective surgery between January 2014 and December 2019 at four academic high-volume institutions. Magnetic resonance tumor regression grade (mrTRG) and pathologic tumor regression grade (pTRG) were reviewed and compared for all the patients. The agreement between radiologist and pathologist was assessed with the weighted k test. Risk factors for poor agreement were investigated using logistic regression. A total of 309 patients were included. Modest agreement was found between mrTRG and pTRG when regression was classified according to standard five-tier systems (k=0.386). When only two categories were considered for each regression system, (pTRG 0-3 vs. pTRG 4; mrTRG 2-5 vs. mrTRG 1) an accuracy of 78% (IC 95% 0.73-0.83) was found between radiologic and pathologic assessment with a k value of 0.185.The logistic regression model revealed that "T3 greater than 5mm extent" was the only variable significantly impacting on disagreement (OR 0.33, 95% CI 0.15-0.68, p=0.0034). Modest agreement exhists between mrTRG and pTRG. The chances of appropriate assessment of the regression grade after neoadjuvant CRT appear to be higher in case of a T3 tumor with at least 5mm extension in the mesorectal fat at the pre-treatment MRI.

Abstract
BACKGROUND AND AIMS Diagnosis and management of inflammatory bowel diseases [IBD] requires a lifelong multidisciplinary approach. The quality of medical reporting is crucial in this context. The present topical review addresses the need for optimised reporting in endoscopy, surgery, and histopathology. METHODS A consensus expert panel consisting of gastroenterologists, surgeons, and pathologists, convened by the European Crohn's and Colitis Organisation, performed a systematic literature review. The following topics were covered: in endoscopy: [i] general IBD endoscopy; [ii] disease activity and surveillance; [iii] endoscopy treatment in IBD; in surgery: [iv] medical history with surgical relevance, surgical indication, and strategy; [v] operative approach; [vi] intraoperative disease description; [vii] operative steps; in pathology: [viii] macroscopic assessment and interpretation of resection specimens; [ix] IBD histology, including biopsies, surgical resections, and neoplasia; [x] IBD histology conclusion and report. Statements were developed using a Delphi methodology incorporating two consecutive rounds. Current practice positions were set when ≥ 80% of participants agreed on a recommendation. RESULTS Thirty practice positions established a standard terminology for optimal reporting in endoscopy, surgery, and histopathology. Assessment of disease activity, surveillance recommendations, advice to surgeons for operative indication and strategies, including margins and extent of resection, and diagnostic criteria of IBD, as well as guidance for the interpretation of dysplasia and cancer, were handled. A standardised report including a core set of items to include in each specialty report, was defined. CONCLUSIONS Interdisciplinary high-quality care requires thorough and standardised reporting across specialties. This topical review offers an actionable framework and practice recommendations to optimise reporting in endoscopy, surgery, and histopathology.

Abstract
BACKGROUND 80% of individuals with cancer will require a surgical procedure, yet little comparative data exist on early outcomes in low-income and middle-income countries (LMICs). We compared postoperative outcomes in breast, colorectal, and gastric cancer surgery in hospitals worldwide, focusing on the effect of disease stage and complications on postoperative mortality. METHODS This was a multicentre, international prospective cohort study of consecutive adult patients undergoing surgery for primary breast, colorectal, or gastric cancer requiring a skin incision done under general or neuraxial anaesthesia. The primary outcome was death or major complication within 30 days of surgery. Multilevel logistic regression determined relationships within three-level nested models of patients within hospitals and countries. Hospital-level infrastructure effects were explored with three-way mediation analyses. This study was registered with ClinicalTrials.gov, NCT03471494. FINDINGS Between April 1, 2018, and Jan 31, 2019, we enrolled 15 958 patients from 428 hospitals in 82 countries (high income 9106 patients, 31 countries; upper-middle income 2721 patients, 23 countries; or lower-middle income 4131 patients, 28 countries). Patients in LMICs presented with more advanced disease compared with patients in high-income countries. 30-day mortality was higher for gastric cancer in low-income or lower-middle-income countries (adjusted odds ratio 3·72, 95% CI 1·70-8·16) and for colorectal cancer in low-income or lower-middle-income countries (4·59, 2·39-8·80) and upper-middle-income countries (2·06, 1·11-3·83). No difference in 30-day mortality was seen in breast cancer. The proportion of patients who died after a major complication was greatest in low-income or lower-middle-income countries (6·15, 3·26-11·59) and upper-middle-income countries (3·89, 2·08-7·29). Postoperative death after complications was partly explained by patient factors (60%) and partly by hospital or country (40%). The absence of consistently available postoperative care facilities was associated with seven to 10 more deaths per 100 major complications in LMICs. Cancer stage alone explained little of the early variation in mortality or postoperative complications. INTERPRETATION Higher levels of mortality after cancer surgery in LMICs was not fully explained by later presentation of disease. The capacity to rescue patients from surgical complications is a tangible opportunity for meaningful intervention. Early death after cancer surgery might be reduced by policies focusing on strengthening perioperative care systems to detect and intervene in common complications.

Abstract
INTRODUCTION The use of electronic media in informed consent giving has become increasingly important in recent years. Due to the easy access to information via electronical media, patients are primed in a heterogeneous manner concerning expectations and wishes regarding surgical interventions. Inherent to its nature elective interventions are critically questioned as there is time for information gathering and reflection. In this study, we set out to investigate the effect of an educational video as a supporting element in the process of informed consent giving for one the most frequently performed interventions in general surgery, namely inguinal hernia repair. METHODS AND ANALYSIS In a multicentre setup, eligible patients for primary inguinal hernia repair will be randomly assigned to one of three groups. All three groups will have a preoperative informed consent discussion with a physician in which they will eventually sign the informed consent sheet if participation is desired. Eventually, all three groups will get an online link. For two groups, the link will lead to a video with audiovisual information (an inguinal hernia video for the intervention group and a mock video for the control group). The intervention video provides basic principles of endoscopic extraperitoneal hernia repair. The second video is similar in length and design and displays general aspects of day surgery in the two study centres. All the three study groups will be provided with a copy of the informed consent form as it is standard by now. The third group's link will lead to the digital version of the informed consent brochure. Primary outcomes will consist of (1) score in a multiple choice test assessing gain of knowledge regarding hernia repair, (2) difference in the State-Trait Anxiety Inventory and (3) patient satisfaction questionnaire Individual Clinician Feedback (ICF, Picker Institute, Germany) as assessed 1-2 days after the first consultation. The study design guarantees double blinding, there will be no unblinding at any point. All patients will receive the same, quality and number of medical consultations as well as in the same surgical treatment. (Minor differences in the total extraperitoneal technique of the surgical treatment due to anatomical or pathophysiological differences are independent of the group allocation). Except for the additional videos, there will be no difference in in the information provided and the treatment prior, during or after the hernia repair. ETHICS AND DISSEMINATION We plan to publish the study in a peer-reviewed journal. The proposed research project has been reviewed by the Cantonal Ethics Committee (BASEC-No 2020-01548). In accordance with national legal regulations in Switzerland stated by the Human Research Act, the proposed project was declared exempt from approval requirement. TRIAL REGISTRATION NUMBER NCT04494087; Pre-results.

Abstract
Background: With the rapid global spread of the acute respiratory syndrome coronavirus 2, urgent health-care measures have been implemented. We describe the organizational process in setting up a coronavirus disease 2019 triage unit in a Swiss tertiary care hospital. Methods: Our triage unit was set-up outside of the main hospital building and consists of three areas: 1. Pre-triage, 2. Triage, and 3. Triage plus. The Pre-triage check-points identify any potential COVID-19-infected patients and re-direct them to the main Triage area where trained medical staff screen which patients undergo diagnostic testing. If testing is indicated, nasopharyngeal swabs are performed. If patients require further investigations, they are referred to Triage plus. At this stage, patients are then discharged home after additional testing or admitted to the hospital for management. Observations: A total of 1265 patients were screened between 10 March 2020 and 12 April 2020 at our Triage unit. Of these, 112 (8.9%) tested positive. 73 (65%) of the positively-tested patients were female and 39 (35%) were male. The mean age for all patients was 43.8 years (SD 16.3 years). Distinguishing between genders, mean age for females was 41.1 (SD 16.5) and mean age for males was 48.6 (SD 14.9), with females being significantly younger than males (p < 0.001). Conclusion: Our triage unit was set-up as part of a large-scale restructuring process. Current challenges include low sensitivity for test results as well as limited staff and resources. We hope that our experience will help other health care institutions develop similar triage systems.

Abstract
BACKGROUND Surgical site infection (SSI) is one of the most common infections associated with health care, but its importance as a global health priority is not fully understood. We quantified the burden of SSI after gastrointestinal surgery in countries in all parts of the world. METHODS This international, prospective, multicentre cohort study included consecutive patients undergoing elective or emergency gastrointestinal resection within 2-week time periods at any health-care facility in any country. Countries with participating centres were stratified into high-income, middle-income, and low-income groups according to the UN's Human Development Index (HDI). Data variables from the GlobalSurg 1 study and other studies that have been found to affect the likelihood of SSI were entered into risk adjustment models. The primary outcome measure was the 30-day SSI incidence (defined by US Centers for Disease Control and Prevention criteria for superficial and deep incisional SSI). Relationships with explanatory variables were examined using Bayesian multilevel logistic regression models. This trial is registered with ClinicalTrials.gov, number NCT02662231. FINDINGS Between Jan 4, 2016, and July 31, 2016, 13 265 records were submitted for analysis. 12 539 patients from 343 hospitals in 66 countries were included. 7339 (58·5%) patient were from high-HDI countries (193 hospitals in 30 countries), 3918 (31·2%) patients were from middle-HDI countries (82 hospitals in 18 countries), and 1282 (10·2%) patients were from low-HDI countries (68 hospitals in 18 countries). In total, 1538 (12·3%) patients had SSI within 30 days of surgery. The incidence of SSI varied between countries with high (691 [9·4%] of 7339 patients), middle (549 [14·0%] of 3918 patients), and low (298 [23·2%] of 1282) HDI (p<0·001). The highest SSI incidence in each HDI group was after dirty surgery (102 [17·8%] of 574 patients in high-HDI countries; 74 [31·4%] of 236 patients in middle-HDI countries; 72 [39·8%] of 181 patients in low-HDI countries). Following risk factor adjustment, patients in low-HDI countries were at greatest risk of SSI (adjusted odds ratio 1·60, 95% credible interval 1·05-2·37; p=0·030). 132 (21·6%) of 610 patients with an SSI and a microbiology culture result had an infection that was resistant to the prophylactic antibiotic used. Resistant infections were detected in 49 (16·6%) of 295 patients in high-HDI countries, in 37 (19·8%) of 187 patients in middle-HDI countries, and in 46 (35·9%) of 128 patients in low-HDI countries (p<0·001). INTERPRETATION Countries with a low HDI carry a disproportionately greater burden of SSI than countries with a middle or high HDI and might have higher rates of antibiotic resistance. In view of WHO recommendations on SSI prevention that highlight the absence of high-quality interventional research, urgent, pragmatic, randomised trials based in LMICs are needed to assess measures aiming to reduce this preventable complication.

Abstract
BACKGROUND The prediction of outcome in pancreatic neuroendocrine tumors (P-NETs) still represents a challenge. Several clinicopathologic parameters have been proposed to predict adverse outcome. The aim of this study was to evaluate the impact of tumor necrosis and angioinvasion on the outcome after curative R0 resection of P-NETs. METHODS We reviewed our institutional experience over the last 30 years. A total of 82 patients with a mean age of 54 years (range 17-83 years) underwent surgical resection of P-NETs during the period from 1964 to 2006. There were 41 men and 41 women. The patients' outcomes after R0 surgical treatment were analyzed in relation to the presence or absence of tumor cell necrosis and angioinvasion as judged by histologic methods. RESULTS The overall (n = 82) 5-year survival was 52.4% (± 6.0%). Forty-eight of the patients underwent a R0 resection successfully. These patients showed a 5-year survival of 59.04% (± 7.8%); the median survival was 101 ± 36 months. Necrosis status was documented on 47 of the R0 resected patients (97.9%). The survival median of patients with tumor cell necrosis was significantly shorter than those without necrosis (41 ± 25 vs. 173 ± 69 months, respectively, P = 0.006). The patients' mean 5-year survival was also significantly decreased (28.9 ± 15.0% vs. 68.5.6 ± 8.9%). Angioinvasion status was documented on 43 of the R0 resected patients (90.0%). The median survival of these patients was decreased from 173 ± 51 to 54 ± 18 months when angioinvasion was observed in the histological sections (P = 0.104). The patients' mean 5-year survival was also decreased from 69.2 ± 9.3% to 35.9 ± 14.0%. CONCLUSIONS Long-term survival of patients with P-NETs is influenced by various pathologic factors. Among our patients, there was not a significant difference in overall survival based on the diameter of the primary tumor or the lymph node status after R0 surgical resection. The presence of necrosis in the TNM and World Health Organization classification for pancreatic endocrine tumor was associated with significant poor overall survival in each classification category. Hence, necrosis represents an independent variable for poor prognosis.

Abstract
Since the introduction of the angiogenic therapy by Folkman et al. in the 1970'ies many antiangiogenic drugs were identified. Only few of them are still now in clinical use. Also the Vascular Endothelial Growth Factor (VEGF), the cytokine with the highest angiogenic activity, has been identified. Its antagonist, Bevacizumab, is produced and admitted for the angiogenic therapy in first line for metastatic colorectal cancer. When we look at preclinical studies, they fail of in vivo models that define the "Drug-Angiogenic-Activity-Index" of angiogenic or antiangiogenic drugs. This work proposes a possible standardized procedure to define the "Drug Angiogenic Activity Index" by counting the vascular intersections (VIS) on the Chorioallantoic Membrane after drug application. The equation was defined as follows: {ΔVIS[Drug]-ΔVIS[Control]} / Δ VIS[Control]. For VEGF a Drug-Angiogenic-Activity-Index of 0.92 was found and for Bevacizumab a -1. This means almost that double of the naturally angiogenic activity was achieved by VEGF on the Chorioallantoic membrane. A complete blocking of naturally angiogenic activity was observed after Bevacizumabs application. Establishing the "Drug-Angiogenic-Activity-Index" in the preclinical phase will give us an impact of effectiveness for the new constructed antiangiogenic drugs like the impact of effectiveness in the cortisone family.

Abstract
UNLABELLED There is a body of evidence showing that several lifestyle and dietary factors are associated with colorectal polyps' formation; however, the magnitude of this association in diverse populations remains unclear. The aim of this study was to investigate this association in a Greek sample. MATERIAL AND METHOD The study comprised of 52 subjects with histologically confirmed advanced colorectal polyps and 52 healthy controls. Data concerning lifestyle and dietary factors were collected using a validated questionnaire. Logistic regression analysis was used to estimate odds ratios and 95% confidence intervals after adjustment for potential confounders. RESULTS Physical activity level (95% CI 0.032-0.953, P = 0.044) and consumption of yoghurt (95% CI 0.969-0.996, P = 0.024), cheese (95% CI 0.932-0.996, P = 0.030), fish (95% CI 0.782-0.964, P = 0.008), vegetables (95% CI 0.965-0.998, P = 0.029), and garlic (95% CI 0.005-0.671, P = 0.022) were inversely associated with colorectal polyps. Increasing age (95% CI 1.005-1.231, P = 0.039) and central obesity (95% CI 1.001-1.019, P = 0.025) were strongly associated with their presence. CONCLUSION Our study indicates that a cluster of modifiable risk factors have significant impact on colorectal polyps' occurrence in Greek population.

Abstract
AIM The variability of prognosis of gastric cancer (GC) within a pathological stage necessitates the identification of subgroups of patients with a more aggressive disease. The role of p53 and Ki67 expression in gastric carcinoma is far from being fully established. The aim of the present study was to evaluate the expression of p53 and Ki67 in gastric cancer and correlate the findings with several clinicopathological features and prognosis. MATERIALS AND METHODS Tissue samples from 93 patients treated by gastric resection for gastric carcinoma between 1996 and 2001 were used. Formalin-fixed paraffin-embedded tumors were studied by immunohistochemistry, using monoclonal antibodies to p53 and Ki67. The results were correlated with clinicopathological features and survival. RESULTS Stronger expression of p53 was related with tumor size greater than 5 cm and advanced stage. Stronger expression of Ki67 correlated with higher ratio of the number of metastatic lymph nodes to the total number of dissected lymph nodes (metastatic lymph node [MLN] ratio) and advanced stage. Moreover, p53 and Ki67 overexpression, tumor size greater than 5 cm, MLN ratio, depth of invasion, lymph node metastasis, stage III and IV and infiltrative macroscopic appearance were adverse prognostic factors. The levels of p53 and Ki67, the MLN ratio, the tumor size (above 5 cm) and the stage of the disease were identified as independent prognostic factors of survival. CONCLUSIONS In gastric cancer, the expression of p53 and Ki67 provides significant information about prognosis. The routine evaluation of p53 and Ki67 levels could be a useful tool in identification of patient with more aggressive disease and contribute to a better therapeutic approach.

Abstract
Duodeno-pancreatic neuroendocrine tumours (DP-ETs) are increasingly diagnosed today due to the widespread use of modern imaging methods. Duodeno-pancreatic endocrine tumours should be treated by radical surgical resection, which offers a high chance for cure when the disease is localized. A high index of suspicion is required in these patients for the presence of a multiple endocrine neoplasia type syndrome. We present four patients with DP-ET surgically treated at our department between 2000 and 2004. Histological/immunohistochemical diagnosis was somatostatin-producing tumour in the first patient, oncocytic endocrine tumour positive for neurone-specific enolase and focally for chromogranin in the second patient, glucagonoma and pancreatic polypeptide-producing endocrine pancreatic tumour in the third patient, and gastrin, somatostatin, calcitonin, insulin and adrenocorticotropic hormone (ACTH)-producing tumour in the fourth. The second patient died 6.5 years following surgery due to disseminated disease.

Abstract
Metastatic disease from cutaneous melanoma can affect all organs of the body, and varies in its biological behavior and clinical presentation. We present the case of a 58-year-old man who arrived at our clinic with acute abdominal pain, which, after investigation, was diagnosed as acute cholecystitis. The patient underwent laparotomy and cholecystectomy. Two years ago, he underwent surgical removal of a primary cutaneous melanoma on his right upper back. Pathological examination revealed the presence of malignant melanoma with a metastatic lesion of the gallbladder.

Abstract
We describe a female patient with ulcerative colitis since the age of 17, who was accidentally diagnosed as having medullary sponge kidney 3 years after the establishment of diagnosis of inflammatory bowel disease. The diagnosis of renal disease was based on the typical appearance of both kidneys on abdominal ultrasound examination and on IV pyelography findings. All other well-known causes of medullary sponge kidney were excluded on the basis of the relevant laboratory investigation. So far, the patient experienced only one episode of urinary infection but no renal colic. Since the time of diagnosis of ulcerative colitis her renal function tests are perfectly normal. She is under maintenance treatment with mesalazine. The benign nature of the situation was explained to her. She was advised to drink at least one and a half litter of water daily, in order to reduce the risk of nephrolithiasis. The combination of the two disorders in our patient is probably the result of a chance. However, taking into account the potentially dangerous long-term results of medullary sponge kidney, we suggest that patients with ulcerative colitis must have a careful ultrasound examination of both kidneys at least at the time of diagnosis of the bowel disease, in order to exclude the possibility of medullary sponge kidney, as conservative measures could result in avoidance of potentially dangerous complications, such as renal stones and urinary infections.

Abstract
INTRODUCTION The levels of circulating proinflammatory cytokines may express the extent of the inflammatory response and their participation in plaque progression and rupture needs to be evaluated. We aimed to investigate differences in circulating levels of proinflammatory cytokines and in plaque infiltration by macrophages between patients undergoing carotid endarterectomy for symptomatic and asymptomatic carotid atherosclerotic disease. METHODS One hundred nineteen patients (91 men and 28 women; mean age 66 +/- 8 years; range 42-83 years) who underwent carotid endarterectomy for significant (>70%) carotid bifurcation stenosis were enrolled in this study. Patients were characterized as symptomatic (n = 62) or asymptomatic (n = 57) after neurological examination. Serum levels of interleukin-6 (IL-6), tumor necrosis factor-alpha (TNF-alpha), IL-1beta, serum amyloid A (SAA), and high-sensitivity C-reactive protein (hs-CRP) were evaluated. Macrophage infiltration of the plaque was assessed quantitatively from endarterectomy specimens using the monoclonal antibody CD68. RESULTS Serum IL-6 levels were significantly higher in patients with symptomatic compared with those with asymptomatic carotid disease (3.3 [2.0-6.5] pg/ml vs 2.5 [1.9-4.1] pg/ml, P = 0.02). TNF-alpha, IL-1beta, SAA, and hs-CRP levels did not differ significantly between the two groups. Symptomatic patients had also more intense macrophage accumulation in the carotid plaque compared with asymptomatic patients (0.6 +/- 0.1% vs 0.4 +/- 0.1%, P < 0.001). Although there were correlations between the levels of the different inflammatory markers, there were no correlation between any of them and the extent of plaque macrophage infiltration. CONCLUSION Patients with symptomatic carotid atherosclerotic disease have elevated serum IL-6 levels compared with asymptomatic patients. Symptomatic patients have also more intense macrophage infiltration of the atherosclerotic plaque suggesting that inflammatory process may contribute to the destabilization of the carotid plaque.

Abstract
INTRODUCTION Multiple endocrine neoplasia type 1 (MEN1) is an autosomal dominant hereditary disorder associated with mutations of the MEN1 gene and characterized by the combined occurrence of tumours of the parathyroid glands, the pancreatic islet cells and the anterior pituitary. AIM To identify MEN1 gene mutations and characterize clinical manifestations in Greek patients with MEN1. PATIENTS AND METHODS We studied four unrelated index patients with MEN1, 17 relatives and 100 control subjects. Among the relatives, seven were clinically and/or biochemically affected, while 10 were unaffected. DNA extraction, polymerase chain reaction (PCR) and direct sequencing of the MEN1 exons 2-10 and exon/intron boundaries were performed according to standard procedures. RESULTS We identified novel MEN1 gene mutations in three out of four index patients (75%) and in all affected (100%) relatives. Novel mutations included: a frameshift mutation in exon 4 (c.684_685insG) at codon 229 (index patient A); a frameshift mutation in exon 8 (c.1160_1170dupAGGAGCGGCCG) involving codons 387-390 (index patient B); and a missense mutation in exon 4 (c.776T > C), which substitutes leucine with proline at codon 259 (L259P) (index patient C). In the fourth index patient, a common polymorphism (D418D) was detected. CONCLUSIONS This is the first report to reveal a high prevalence of novel MEN1 gene mutations among Greek MEN1 patients with apparent absence of genotype-phenotype correlation. Because of the small number of patients examined, the high prevalence detected might be a chance phenomenon.

Abstract
UNLABELLED Acute idiopathic pancreatitis seems to represent a rare extraintestinal manifestation of Crohn's disease usually appearing after the establishment of diagnosis of the intestinal disorder. The aim of this study was to describe the clinicoepidemiological characteristics and clinical course of three patients with Crohn's disease who developed acute idiopathic pancreatitis years before the establishment of diagnosis intestinal disease. DESCRIPTION OF CASES All patients were suffering from Crohn's disease. In all patients, an extensive work-up aiming to identify an etiological factor involved in the pathogenesis of acute pancreatitis was negative. The main clinical characteristics of the patients were the young age, the mild or moderate degree of severity of pancreatitis, and the concurrent involvement of small and large bowel from Crohn's disease in two of them. There was no preference for either male or female sex. The course of pancreatitis was favorable in all patients. During the follow-up period, ranging from 2 to 8 years, no exacerbation of pancreatitis was noticed. CONCLUSION This case-series suggests that acute idiopathic pancreatitis could precede diagnosis of Crohn's disease. Clinicians must bear in mind the possibility of the existence of Crohn's disease when they are confronting a young patient with clinical and laboratory features of acute idiopathic pancreatitis.

Abstract
In the era of breast conservation surgery, sentinel lymph node biopsy is increasingly used. Sentinel lymph node biopsy can be performed by using the blue dye technique, lymphoscintigraphy and the combined method. Sentinel lymph node biopsy is a minimally invasive technique which has many advantages over the classical axillary (level I and II) lymph node dissection. However, false negative results - albeit rare in experienced hands - may be a serious limitation. The physician should be familiar with this new technique. This will allow him or her to be more actively involved in the management of breast cancer patients and to understand the available management options for these patients.

Abstract
OBJECTIVE This study investigates the role of liquid-based cytology by ThinPrep technique in the detection of thyroid lesions. METHODS In all, 252 specimens from 157 patients for pre-operative evaluation of thyroid nodules, prepared by the ThinPrep, were examined. In all cases thyroidectomy followed the initial cytological evaluation. All cytological diagnoses were correlated to the histological ones. RESULTS According to our findings, a sensitivity of 87.80%, a specificity of 99.50%, a positive predictive value of 97.30%, a negative predictive value of 97.56% and an overall accuracy of 97.52% were observed in fine needle aspiration cytology in correlation to the histological diagnosis after thyroidectomy. CONCLUSIONS ThinPrep technique is a valid method for the pre-operative cytological diagnosis of thyroid nodules, offering the possibility of ancillary techniques, such as immunocytochemical and molecular methods and can, therefore, be potentially complementary to histological evaluation for further investigation of follicular lesions.

Abstract
BACKGROUND Papillary thyroid microcarcinoma (PTMC) is a relatively common entity in the general population. AIM To present our experience with papillary thyroid microcarcinoma of the thyroid as an incidental finding in patients treated surgically for presumably benign thyroid disease. SETTINGS AND DESIGN Histology reports of patients treated surgically with a preoperative diagnosis of benign thyroid disease were reviewed to identify patients with PTMC. Patients with a preoperative diagnosis of thyroid cancer were excluded from this study. MATERIALS AND METHODS The files of 380 patients who underwent surgery for presumably benign thyroid disease in our hospital from 1990 to 2002 were reviewed. Data regarding patient's demographics, pathology findings, management and outcomes, were retrieved. STATISTICAL ANALYSIS USED The findings are expressed as absolute numbers and as percentages (with reference to the total number of patients of this study). RESULTS Twenty-seven patients with PTMC diagnosed incidentally following thyroid surgery for presumably benign thyroid disease (27/380 or 7.1%) (multinodular goiter = 20 patients, follicular adenoma = 6 patients, diffuse hyperplasia of the thyroid = 1 patient) are presented. Mean diameter of PTMC was 4.4 mm. In 11 patients (40.7%) the tumor was multifocal and in about half of them tumor foci were found in both thyroid lobes. In two patients the tumor infiltrated the thyroid capsule. Total/near-total thyroidectomy was performed in all these patients (in three as completion thyroidectomy). All patients received suppression therapy and 20 of them underwent adjuvant radioiodine therapy. Follow-up (mean 4.56 years, range 1-12 years) was completed in 25 patients; all these patients were alive and disease-free. CONCLUSIONS PTMC is not an uncommon incidental finding after surgery for presumably benign thyroid disease (7.1% in our series). The possibility of an underlying PTMC should be taken into account in the management of patients with nodular thyroid disease; total/near total thyroidectomy should be considered, at least in selected patients with presumably benign nodular thyroid disease.

Abstract
BACKGROUND The objective of this study was to evaluate the expression of bcl-2 in UICC stage I and stage III (Dukes's stage B and C) colorectal adenocarcinoma and to examine its association with clinicopathological features, c-erbB-2, p53, ki-67, CD44, laminin and collagen IV and long term outcome. METHODS Paraffin embedded specimens from 61 patients with UICC stage I (Dukes's stage B) and 39 patients with UICC stage III (Dukes's stage C) colorectal adenocarcinoma who were treated with surgery were assessed. We determined by immunohistochemistry the expression of bcl-2, c-erB-2, p53, ki-67, CD44, laminin and collagen IV with 5 year follow up. RESULTS Cytoplasmic staining of the bcl-2 gene product was seen in the tumour cells of 27 cases (27%). Expression of bcl-2 protein was unrelated to patient sex, age, tumour site or tumour grade, but was related to tumour stage (p = 0.012). No significant association was demonstrated between bcl-2 and c-erbB-2, p53 or CD44. However, there was very strong evidence of correlation between bcl-2 staining and ki-67, laminin and collagen IV. There was a trend towards increased survival in patients whose tumours expressed bcl-2 protein. When a correlation between bcl-2 and the other markers had been made the positive expression of bcl-2 was beneficial. CONCLUSIONS The results from this study would suggest that expression of bcl-2 appear to be useful in selecting a group of colorectal cancer patients with a better prognosis.

Abstract
This study aimed (1) to develop a simple scoring system incorporating ultrasound (US) examination and clinical or laboratory predictors for increasing diagnostic accuracy in acute appendicitis (AA), and (2) to evaluate the performance of the scoring system as compared to that of previous models. Fifteen variables including US assessment for patients admitted with suspected AA were considered in multivariate analysis using the finding of AA at operation as the end point (internal study). The new score, together with 11 previous ones, was applied to a prospective independent population of subjects with suspected AA, and the respective performances were compared (external validation study). Among 303 patients (170 males, mean age 28.3 +/- 13.3 years) of the internal study, 161 went on to surgery, and 130 had AA at operation. Four independent correlates of AA were identified and used for the derivation of the following integer-based scoring system: number of points = 6 for US demonstrating AA + 4 for tenderness in the right lower quadrant + 3 for rebound tenderness + 2 for leukocyte count >12,000/microl. In the external study (201 subjects, 105 males, mean age 28.7 +/- 11.9 years, 109 operated, 87 with AA), when the cut-off of >/or = 8 points for AA was used, sensitivity, specificity, accuracy, and area under the curve of the proposed score were 95.4%, 97.4%, 96.5%, and 93%, respectively, exceeding noticeably the previous models. The proposed scoring system introduces a quantitative combination of the clinical evaluation with US imaging and a marker of inflammatory response, which may enhance the diagnostic accuracy for subjects with suspected AA especially in geographical areas where CT scanning is not readily available on a 24-hour basis.

Abstract
The objective of this study was to evaluate the expression of bcl-2 in Dukes' stage B and stage C (AJCC/UICC stage I and III) colorectal adenocarcinomas and to examine its association with clinicopathological features, p53, ki-67 and long term outcome. Paraffin embedded specimens from 61 patients with Dukes' stage B (AJCC/UICC stage I) and 39 patients with Dukes' stage C (AJCC/UICC stage III) colorectal adenocarcinoma who were treated with surgery were assessed. We used immunohistochemistry to determine the expression of bcl-2, p53 and ki-67 with a five-year follow-up. Positive bcl-2 expression was seen in 27 cases (27%). Expression of bcl-2 protein was related to tumor stage (p=0.0117). There was very strong evidence of an association between bcl-2 staining and ki-67 score (p<0.001). There was a trend towards increased survival in patients whose tumors expressed bcl-2 protein (p=0.001). When entered into a multivariate analysis model, which also included p53 and stage, bcl-2 staining emerged as a prognostic indicator variable. Expression of bcl-2 appears to be useful in selecting a group of colorectal cancer patients with a better prognosis.

Abstract
To investigate the expression of CD44 in colorectal cancer and examine its association with clinicopathological features, bcl-2, p53 and long-term outcome, paraffin-embedded tumour specimens from 61 patients with Dukes stage B (AJCC/UICC stage I) and 39 patients with Dukes stage C (AJCC/UICC stage III) colorectal adenocarcinoma were assessed by immunohistochemistry. The expression of CD44, bcl-2 and p53 were correlated with 5-year follow-up. Low CD44 expression was present in 30%, moderate in 30% and extensive in 40% of cases. It was not related to patient sex and age but was related to tumour differentiation, stage and tumour site. No association was demonstrated between CD44 and bcl-2. However, there was significant evidence of an association between CD44 and p53 in 66 cases in which p53 was previously assessed. There was a trend towards increased survival in patients whose tumours expressed lower levels of CD44 protein. When entered into multivariate analysis model, which also included bcl-2 and p53, CD44 staining emerged as an indicator of poor prognosis in colorectal cancer patients.

Abstract
AIM To investigate the pituary, genitalia, adrenal, thyroid, parathyroid and pancreatic endocrine function of a female patient aged 37 with abetalipoproteinemia at the time of diagnosis and 5 years thereafter (after application of a modified diet). SUBJECT-METHODS: Serum concentrations of cortisol, A4, ACTH, aldosteron, renin, dehydroepiandrosterone sulfate (DHEA-5), progesterone, 17-OH progesterone, testosterone, SH13G, estradiol, luteinizing hormone, follicle stimulating hormone, T3, T4, TSH, FT3, FT4, parathormone, osteocalcin, prolactin, proinsuline, insulin, glucagon, somatomedin-C (Insulin-like Growth Factor-1, IGF-1), IG171-13P3, 25 (OH) Vitamin D3 and 1-25 (OH) 2 Vitamin D3, were measured by radioimmunoassay. Synactlien test, and 24-hour urine cortisol, were also estimated. Serum leptin estimation was carried-out using a sensitive enzymatic technique. Ionized part of serum calcium was measured by the use of a special machine (CORNING), while bone alkaline phosphatase was measured by radioimmunoassay. RESULTS Serum progesterone and 17-OH-progesterone were reduced in both examinations. Estimation of serum progesterone performed on the 21th day of the menstrual cycle revealed again values below the lowest normal limit. Serum prolactin was increased both in rest and during movement. The levels of both, somatomedin-C (IGF-1) and leptin were below the lowest normal limit. Despite normal serum parathormone, serum-ionized calcium and 25-OH vitamin D were low, while serum bone alkaline phosphatase was increased. Serum proinsulin was increased, and serum insulin was low. Serum thyroid hormone, glucagon, parathormone, FSH, LH, ACTH, testosterone, estradiol and SH13G were normal. The hormonal profile of the patient estimated 5 years later did not differ substantially suggesting that the metabolic improvement due to the adoption of the modified diet had not any significant impact on it. CONCLUSION Female patients with abetalipoproteinernia have reduced production of progesterone by the corpus luteum and slightly abnormal bone metabolism. The reduced production of progesterone is probably due to the low levels of serum LDL and cholesterol, while reduced serum levels of Leptin and IG17-1 are probably due to the impairment nutritional status. The adoption of a modified diet does not alter the hormonal profile significantly.

Abstract
BACKGROUND The aim of this study was to determine whether the efficacy of the combination of 5-fluorouracil (5-FU), leucovorin (LV) and radiation therapy (RT) could be improved by the addition of interferon-alpha2b (IFN-alpha) in patients who have had a 'curative' resection, for rectal adenocarcinoma (Dukes' B2/C; T3 N0, T4 N0, N1-3). PATIENTS AND METHODS A total of 207 eligible patients with a performance status of 0 or 1 were randomized postoperatively between days 21 and 70 to one of the two treatment groups: group A, LV 20 mg/m2 i.v. bolus and 5-FU 425 mg/m2 i.v. days 1-5 and 29-33, LV 20 mg/m2 and 5-FU 400 mg/m2 days 57-60 and 85-88, LV 20 mg/m2 and 5-FU 380 mg/m2 days 1-5 and 29-33 with the second day 1 occurring 28 days after the completion of RT (45 Gy); group B, LV, 5-FU and RT as in group A, and IFN-alpha 5 x 10(6) IU s.c. three times during each week chemotherapy is given. RESULTS 104 patients were randomized into group A and 103 into group B. There was no statistically significant difference in either disease-free survival or overall survival between the two groups. Toxicity was also the same, except for the flu-like syndrome associated with the IFN-alpha administration. CONCLUSIONS There was no difference in efficacy between the two combinations. Toxicity was greater with the LV + 5-FU + IFN-alpha regimen because of the flu-like syndrome.

Abstract
We report the absence of beta-catenin mutations in 63 sporadic colorectal carcinomas (SCRCs) with demonstrated decreased beta-catenin and E-cadherin mRNA expression and E-cadherin protein expression in a subset of carcinomas examined, suggesting that beta-catenin mutations are an extremely rare phenomenon in SCRCs and are not responsible for the transcriptional impairment of the beta-catenin/E-cadherin adhesion complex observed in these tumours.

OBJECTIVE To identify preventable prehospital deaths, caused by trauma. DESIGN Analysis of 82 trauma victims who were dead on arrival (DOA) into our hospital. SETTING General Hospital of Piraeus, Greece. MATERIALS AND METHODS Evaluation of the autopsy findings of 82 DOAs. MEASUREMENTS Demographic, autopsy, and toxicology data, ICD9 codes, Abbreviated Injury Score (AIS)-90, Injury Severity Score (ISS)-body regions, central nervous system (CNS) deaths, non-CNS deaths, p values, and opinion of a clinical assessor. MAIN RESULTS The 29 (35.36%) DOAs had at least one AIS6 injury. Extracranial hemorrhage, airway, and breathing dysfunction were contributing factors of death of 27 "possibly preventable" CNS deaths, and the causes of death for the 20 non-CNS deaths. p value (0.5) indicated that 24 (29.26%) of the DOAs expected to survive. The clinical assessor characterized four (4.87%) as "definitely preventable" and 35 (42.65%) as "possibly preventable" deaths. CONCLUSIONS Upgrading of the emergency medical care service is required.

Abstract
Acute renal failure (ARF) induced with large doses of Gentamicin (GM) (an aminoglycoside) was associated with increased urinary TXB (TXA) excretion which provoked a decrease of the ratios of urinary PGE2/TXB2 and 6-keto-PGF1 alpha (PGI2)/TXB2 excretions. Furthermore, as indicated by light microscopy most of the epithelial cells lining the proximal tubules show obvious lesions varying from swelling of their cytoplasm to complete necrosis. Either the inhibitor, OKY-O46, of TXA-synthetase, or volume expansion (VE) with isotonic saline (IS) of the experimental animals diminished urinary TXB excretion which provoked 1) augmentation of the ratios of urinary PGE/TXB and 6-keto-PGF1 alpha/TXB excretions, 2) elevation of creatinine clearance (Ccr) and 3) diminution of proteinuria (PU). This protection against ARF-by OKY-O46 and VE can a can be seen in microscopic sections where necrosis of proximal tubules is almost absent. Only a few proximal tubules show swelling of their epithelial cells and some focal areas of tubule necrosis. We suggest that the metabolites of arachidonic acid (AA), TXA2 a (potent vasoconstrictor agent) and prostaglandins (PGE2 and PGI2), (potent vasodilator factors), play an important role in the development (TXA2) or in the prevention (PGs) of ARF induced by this antibiotic.

Abstract
In polytraumatised or septic patients without adequate medical prophylaxis the incidence-rate of postoperative complications is very high. The incidence-rate of acute mucosal stress lesions is to be expected 100 per cent. The parenteral application of pirenzepine shows in comparison to placebo a clear protective effect measured as incidence-rate of stress lesion (p greater than 0,05) and occurrence of bleeding (p greater than 0,01).
