Background:\ud \ud Ensuring adequate knowledge about palliative care and positive attitudes towards death and dying are crucial educational aspects when preparing undergraduate nursing students to respond effectively to the complexities of care for people affected by a progressive, life-limiting illness. In undergraduate nursing education in Greece, the level of students' attained knowledge and developed attitudes towards palliative and end-of-life care remain unknown.\ud Purpose:\ud \ud To investigate undergraduate nursing students' knowledge about palliative care and attitudes towards death and end-of-life care, and explore demographic and academic factors as potential moderators of student knowledge and attitudes.\ud Methods:\ud \ud We conducted a descriptive, cross-sectional, questionnaire-based survey. We recruited 2nd, 3rd and 4th year undergraduate nursing students from the country's two University Faculties. Participants completed a demographic form, the Palliative Care Quiz for Nursing (PCQN), and the Frommelt Attitudes Towards Care of the Dying (FATCOD) questionnaire.\ud Results:\ud \ud The final sample was 529 students (response rate = 87.6%). Mean total PCQN scores revealed low levels of knowledge. Knowledge about pain/symptom management and psychosocial/spiritual care was insufficient. Mean total FATCOD scores indicated positive, liberal and supportive attitudes towards end-of-life care, with 60% of respondents keen to care for a dying person and their family. We noted less positive attitudes mainly in relation to student comfort with the care of a dying person and his/her imminent death. Academic parameters (year of study) and student demographic characteristics (older age) were the most significant moderators of both knowledge and attitudes. Greater knowledge about palliative care was a relatively weak, yet significant, predictor of more liberal attitudes towards care of the dying.\ud Conclusion:\ud \ud Our findings suggest that structured courses in palliative care can be a core part of undergraduate nursing education. Specific attention could be given to such areas patient-health professional communication, misconceptions and biases towards death and dying, and comfort in caring for the dying in order to prepare student nurses to psychologically deal with the sensitive and challenging process of death and dying.

Objective To evaluate effects of remote monitoring of adjuvant chemotherapy related side effects via the Advanced Symptom Management System (ASyMS) on symptom burden, quality of life, supportive care needs, anxiety, self-efficacy, and work limitations. Design Multicentre, repeated measures, parallel group, evaluator masked, stratified randomised controlled trial. Setting Twelve cancer centres in Austria, Greece, Norway, Republic of Ireland, and UK. Participants 829 patients with non-metastatic breast cancer, colorectal cancer, Hodgkin’s disease, or non-Hodgkin’s lymphoma receiving first line adjuvant chemotherapy or chemotherapy for the first time in five years. Intervention Patients were randomised to ASyMS (intervention; n=415) or standard care (control; n=414) over six cycles of chemotherapy. Main outcome measures The primary outcome was symptom burden (Memorial Symptom Assessment Scale; MSAS). Secondary outcomes were health related quality of life (Functional Assessment of Cancer Therapy—General; FACT-G), Supportive Care Needs Survey Short-Form (SCNS-SF34), State-Trait Anxiety Inventory—Revised (STAI-R), Communication and Attitudinal Self-Efficacy scale for cancer (CASE-Cancer), and work limitations questionnaire (WLQ). Results For the intervention group, symptom burden remained at pre-chemotherapy treatment levels, whereas controls reported an increase from cycle 1 onwards (least squares absolute mean difference −0.15, 95% confidence interval −0.19 to −0.12; P Conclusions Significant reduction in symptom burden supports the use of ASyMS for remote symptom monitoring in cancer care. A “medium” Cohen’s effect size of 0.5 showed a sizable, positive clinical effect of ASyMS on patients’ symptom experiences. Remote monitoring systems will be vital for future services, particularly with blended models of care delivery arising from the covid-19 pandemic. Trial registration Clinicaltrials.gov NCT02356081 .

Purpose: The present study assesses the relationship between patient dignity in advanced cancer and the following variables: psychological distress, preparatory grief, and sociodemographic and clinical characteristics. Methods: The sample consisted of 120 patients with advanced cancer. The self-administered questionnaires were as follows: the Preparatory Grief in Advanced Cancer Patients (PGAC), the Patient Dignity Inventory–Greek (PDI-Gr), the Greek Schedule for Attitudes toward Hastened Death (G-SAHD), and the Greek version of the Hospital Anxiety and Depression Scale (G-HADS). Results: Moderate to strong statistically significant correlations were found between the 4 subscales of PDI-Gr (psychological distress, body image and role identity, self-esteem, and social support) with G-HADS, G-SAHD, and PGAC ( P < .005), while physical distress and dependency was moderately correlated with depression. Multifactorial analyses showed that preparatory grief, depression, and age influenced psychological distress, while preparatory grief, depression, and performance status influenced body image and role identity. Conclusions: Preparatory grief, psychological distress, and physical symptoms had significant associations with perceptions of dignity among patients with advanced cancer. Clinicians should assess and attend to dignity-distressing factors in the care of patients with advanced cancer.

Context The patient dignity inventory (PDI) is an instrument to measure dignity distressing aspects at the end of life. Objectives The aims of the present study were the translation of the PDI in Greek language as well as to measure its psychometric aspects in a palliative care unit. Methods A back-translation method was obtained at the Greek version. One hundred twenty advanced cancer patients completed the Greek version of the PDI, the Greek hospital anxiety and depression scale, the Greek schedule of attitudes toward hastened death (SAHD-Gr), and the Greek 12-item short form health survey. Results Confirmatory factor analysis failed to fit to the original instrument's structure and exploratory factor analysis was conducted revealing five factors ("Psychological Distress," "Body Image and Role Identity," "Self-Esteem," "Physical Distress and Dependency," and "Social Support"). The psychometric analysis of the PDI-Gr demonstrated a good concurrent validity, and the instrument discriminated well between subgroups of patients regarding age differences. Cronbach α were between 0.71 and 0.9 showing a good internal consistency. Conclusion The Greek version of the PDI showed good psychometric properties in advanced cancer patients, supported the usefulness of the instrument assessing the sense of dignity distressing aspects of the terminally ill cancer patients.

Effective symptom management is a critical component of cancer treatment. Computational tools that predict the course and severity of these symptoms have the potential to assist oncology clinicians to personalize the patient’s treatment regimen more efficiently and provide more aggressive and timely interventions. Three common and inter-related symptoms in cancer patients are depression, anxiety, and sleep disturbance. In this paper, we elaborate on the efficiency of Support Vector Regression (SVR) and Non-linear Canonical Correlation Analysis by Neural Networks (n-CCA) to predict the severity of the aforementioned symptoms between two different time points during a cycle of chemotherapy (CTX). Our results demonstrate that these two methods produced equivalent results for all three symptoms. These types of predictive models can be used to identify high risk patients, educate patients about their symptom experience, and improve the timing of pre-emptive and personalized symptom management interventions.

Context Risk profiling of oncology patients based on their symptom experience assists clinicians to provide more personalizedsymptom managementinterventions. Recent findings suggest that oncology patients with distinct symptom profiles can be identified using a variety of analytic methods. Objectives The objective of this study was to evaluate the concordance between the number and types of subgroups of patients with distinct symptom profiles usinglatent class analysisand K-modes analysis. Methods Using data on the occurrence of 25 symptoms from the MemorialSymptom AssessmentScale, that 1329 patients completed prior to their next dose of chemotherapy (CTX), Cohen'skappa coefficientwas used to evaluate for concordance between the two analytic methods. For both latent class analysis and K-modes, differences among the subgroups in demographic, clinical, and symptom characteristics, as well as quality of life outcomes were determined using parametric andnonparametric statistics. Results Using both analytic methods, four subgroups of patients with distinct symptom profiles were identified (i.e., all low, moderate physical and lower psychological, moderate physical and higher Psychological, and all high). The percent agreement between the two methods was 75.32%, which suggests a moderate level of agreement. In both analyses, patients in the all high group were significantly younger and had a highercomorbidityprofile, worse Memorial Symptom Assessment Scale subscale scores, and poorer QOL outcomes. Conclusion Both analytic methods can be used to identify subgroups of oncology patients with distinct symptom profiles. Additional research is needed to determine which analytic methods and which dimension of the symptom experience provide the most sensitive and specific risk profiles.

Introduction While some evidence exists that real-time remote symptom monitoring devices can decrease morbidity and prevent unplanned admissions in oncology patients, overall, these studies have significant methodological weaknesses. The electronic Symptom Management using the Advanced Symptom Management System (ASyMS) Remote Technology (eSMART) study is designed to specifically address these weaknesses with an appropriately powered, repeated-measures, parallel-group stratified randomised controlled trial of oncology patients. Methods and analysis A total of 1108 patients scheduled to commence first-line chemotherapy (CTX) for breast, colorectal or haematological cancer will be recruited from multiple sites across five European countries. Patients will be randomised (1:1) to the ASyMS intervention (intervention group) or to standard care currently available at each site (control group). Patients in the control and intervention groups will complete a demographic and clinical questionnaire, as well as a set of valid and reliable electronic patient-reported outcome measures at enrolment, after each of their CTX cycles (up to a maximum of six cycles) and at 3, 6, 9 and 12 months after completion of their sixth cycle of CTX. Outcomes that will be assessed include symptom burden (primary outcome), quality of life, supportive care needs, anxiety, self-care self-efficacy, work limitations and cost effectiveness and, from a health professional perspective, changes in clinical practice (secondary outcomes). Ethics and dissemination Ethical approval will be obtained prior to the implementation of all major study amendments. Applications will be submitted to all of the ethics committees that granted initial approval. eSMART received approval from the relevant ethics committees at all of the clinical sites across the five participating countries. In collaboration with the European Cancer Patient Coalition (ECPC), the trial results will be disseminated through publications in scientific journals, presentations at international conferences, and postings on the eSMART website and other relevant clinician and consumer websites; establishment of an eSMART website (www.esmartproject.eu) with publicly accessible general information; creation of an eSMART Twitter Handle, and production of a toolkit for implementing/utilising the ASyMS technology in a variety of clinical practices and other transferable health care contexts.

Objective The purpose of this study was to evaluate the impact of ATLS ® on trauma mortality in a non-trauma system setting. ATLS represents a fundamental element of trauma training in every trauma curriculum. Nevertheless, there are limited studies in the literature as for the impact of ATLS training in trauma mortality, especially outside the US. Design This is a prospective observational study. The primary end point was to investigate factors that affect mortality of trauma patients in our health care system. We performed a multivariate analysis for this purpose and we identified ATLS certification as a predictor of overall mortality. Following this finding we stratified patients according to the severity of injury as expressed by the ISS score and we compared outcome between those treated by an ATLS certified physician and those treated by non-certified ones. Main outcome measures Trauma volume and demographics of trauma patients, factors that affect mortality of traumatized patients and mortality between patients treated by ATLS ® certified and non-certified physicians. Results In total, 8862 trauma patients were included in the analysis. The majority of trauma patients (5988, 67.6%) were treated by a general surgeon, followed by those treated by an orthopedic surgeon (2194, 24.8%). There were 446 deaths in the registry but, 260 arrived dead in the Emergency Department and were excluded from the analysis. Multivariate analysis of the 186 deaths that occurred in the hospital revealed age, high ISS score, low GCS score, urban location of injury, neck injury and ATLS ® certification as factors predisposing to mortality. Cross tabulation of ATLS ® certification and ISS of the trauma patients shows that those treated by certified physicians died more often in all subcategories of ISS score ( p Conclusions In Greece, with no formal trauma system implementation, ATLS ® certified physicians achieve worse outcomes than their non-certified colleagues when managing trauma patients. We believe that these findings must be interpreted in the context of the National health care system. There is considerable room for improvement in our country, and further analysis is required.

The purpose of this study was to evaluate the incidence of TBI in Greece and to provide evidence on the epidemiologic characteristics of the disease.This is a prospective observational study initiated by the Hellenic Society of Trauma and Emergency Surgery. Thirty hospitals participated in the registry. All trauma patients requiring admission transfer to a higher level centre and those who arrived dead were included in the study. This report evaluated the epidemiologic characteristics of patients with brain trauma, the cause and the severity of the injury and the final outcome.Eight thousand eight hundred and sixty-two patients were included in the registry. Of them, 3383 had at least one brain injury. There were 2451 males and 932 females. Traffic accidents were the leading cause of TBI (54.1%), followed by falls (27.7%). The most affected age group was the 15-44 year olds (48.0%), but TBIs were more lethal in the 45-64 age group (17.8%). Interestingly, a 3.4% mortality was recorded if a TBI was present, even if ISS was relatively low (0-9 ISS group).TBI is a major element of trauma. Knowledge of the epidemiologic characteristics of the disease is imperative for adequate planning and future quality assessment.

Hemostasis in thyroid surgery is of utmost importance for a successful surgery and an uneventful postoperative course. The present article reports a single surgeon's 3-year experience in the use of the harmonic scalpel. The device was developed in the early 1990s and offered adequate and safe hemostasis for vessels up to 3 mm in width.This was a prospective observational study. Data sheets from all patients who had surgery by a single endocrine surgeon in the period from 1999 to 2004 were evaluated. Patients were divided into 3 groups based on the surgical technique used: group I comprised the conventional knot-and-tie technique, group II comprised the ligation of all but the superior thyroid vessels with a scalpel, and group III comprised patients in whom the device was used exclusively. The groups were compared in regard to surgical time, cost, and complication rate.A total of 272 patients were included in the study: 107 patients were included in group I, 77 in group II, and 88 group III. The surgical time of group I differed significantly compared with groups II and III (P.0001 in both cases). Surgical times between groups II and III did not differ significantly (P = .701).The use of the harmonic scalpel reduces surgical time, but it increases the cost of the surgery. It is our belief that by including in the absolute cost the time saved and the reduction in human resources needed, the use of the scalpel would prove to be economic.

To investigate whether apoptosis is a possible mechanism of brain dysfunction occurring in septic syndrome.Experimental prospective study.Laboratory of Surgical Research at the University of Athens.Male pathogen-free Wistar rats.Rats (n = 112) were subjected to sepsis by cecal ligation and puncture. Sham-operated animals (n = 40) underwent the same procedure but without ligation or puncture. Septic animals were either randomly divided (n = 62) in six groups and studied at 6, 12, 24, 36, 48, and 60 hrs after the operation or monitored (n = 50) for 48 hrs as a survival study group. Sham-operated animals were killed at 6, 12, 24, 36, 48, and 60 hrs after the procedure. Brain and cecum were then removed and postfixed in paraffin sections. Apoptosis was evaluated by light microscopy in hematoxylin and eosin-stained specimens and by transmission electron microscopy. In paraffin-embedded sections, immunostaining for bax, bcl-2, cytochrome c, and caspase-8 was done.In septic rats, increased apoptosis was detected in neurons of the CA1 region of the hippocampus, in choroid plexus, and in Purkinje cells of the cerebellum. Bax immunopositivity was found decreased after the septic insult (p =.03). Bax immunoreactivity was altered as the septic syndrome evolved; it was up-regulated in the early stages (6-12 hrs) and progressively decreased in the late phases (p =.001). Cytochrome c presented a similar regional pattern of expression and was found to be the sole gene marker carrying an independent prognostic role (p =.03). Both bcl-2 and caspase-8 expression remained at constant levels at all times evaluated.There is evidence that more neurons undergo apoptosis during sepsis than in normal brain tissue in certain sites where the blood-brain barrier is compromised. In this phenomenon, mitochondrial gene regulators such as bax and products such as cytochrome c seem to play important regulating and prognostic roles, respectively.

Purpose Caregiving burden affects the lives of family members providing care to patients with advanced cancer, with a host of factors possibly contributing to this. The aim of this study was to explore the effects of patient and caregiver variables on the perceptions of burden in families caring for a loved one living with advanced cancer in Greece. Methods A convenience sample of 100 pairs of patients receiving palliative radiotherapy for advanced cancer and their respective primary family caregivers were consecutively recruited at one radiotherapy centre. Patients and caregivers completed a set of questionnaires during face-to-face interviews. Correlational and multiple regression analyses were performed to identify potential predictors of caregiving burden. Results Caregiving burden was linked to both patient (gender, age, past surgery or chemotherapy treatment, depression and impact of cancer-related symptoms) and caregiver variables (gender, family status, education, place of residence, previous experience of care, employment status, difficulty of caregiving, anxiety and depression). In multiple regression analyses, caregiving burden was significantly predicted by caregivers' depressed mood, perceived difficulty of caregiving, family status, employment status, as well as by patients' past surgery, in a model that explained 49% of the total variance. Conclusions Greek family caregivers reporting greater depressive mood and difficulty with caregiving tasks, those married, those not employed, and those who cared for patients who had not undergone surgery were found at greater distress and disadvantage. Systematic assessment and intervention strategies are required to identify these vulnerable carers and help them cope when sharing in patient's cancer experience.

Objective: To evaluate Acute Physiology and Chronic Health Evaluation (APACHE) II and Simplified Acute Physiology Score (SAPS) II scoring systems in a single intensive care unit (ICU), independent from the ICUs of the developmental sample; and to compare the performance of APACHE II and SAPS II by means of statistical analyses in such a clinical setting. Design: Prospective, cohort study. Setting: A single ICU in a Greek university hospital. Patients: In a time interval of 5 yrs, data for 681 patients admitted to our ICU were collected. The original exclusion criteria of both systems were employed. Patients

To present a new technique of end-to-side, duct-to-mucosa pancreaticojejunostomy with seromuscular jejunal flap formation, and insertion of a silicone stent.We present an end-to-side, duct-to-mucosa pancreaticojejunostomy with seromuscular jejunal flap formation, and the insertion of a silicone stent. This technique was performed in thirty-two consecutive patients who underwent a pancreaticoduodenectomy procedure by the same surgical team, from January 2005 to March 2011. The surgical procedure performed in all cases was classic pancreaticoduodenectomy, without preservation of the pylorus. The diagnosis of pancreatic leakage was defined as a drain output of any measurable volume of fluid on or after postoperative day 3 with an amylase concentration greater than three times the serum amylase activity.There were 32 patients who underwent end-to-side, duct-to-mucosa pancreaticojejunostomy with seromuscular jejunal flap formation. Thirteen of them were women and 19 were men. These data correspond to 40.6% and 59.4%, respectively. The mean age was 64.2 years, ranging from 55 to 82 years. The mean operative time was 310.2 ± 40.0 min, and was defined as the time period from the intubation up to the extubation of the patient. Also, the mean time needed to perform the pancreaticojejunostomy was 22.7 min, ranging from 18 to 25 min. Postoperatively, one patient developed a low output pancreatic fistula, three patients developed surgical site infection, and one patient developed pneumonia. The rate of overall morbidity was 15.6%. There was no 30-d postoperative mortality.This modification appears to be a significantly safe approach to the pancreaticojejunostomy without adversely affecting operative time.

Administration of immuno-enhanced nutritional support may decrease postoperative morbidity, mortality, and infectious complications in cancer patients. The aim of this study was to verify that perioperative enteral diet, enriched with the nutrients arginine, ribonucleic acid (RNA), and omega-3 fatty acids improves outcomes of head and neck cancer patients undergoing major surgery. Forty patients with squamous cell carcinoma of the head and neck were studied. Group 1 received no preoperative nutritional support, whereas Group 2 received an oral formula with nutrients arginine, RNA, and omega-3 fatty acids. After surgery, Group 1 received a standard enteral formula, whereas Group 2 received an enriched enteral formula. Albumin (g/dl), prealbumin, fibrinogen, CRP, Il-6, and TNFa were measured 5 days before and 8 days after surgery. No statistically significant difference was observed for all the evaluated markers between postoperative and preoperative levels for both groups. The rate of complications was significantly reduced in the total number of patients receiving immunonutrition and in the particular subgroup of well-nourished patients receiving an immuno-enhanced diet. Perioperative enteral immuno-enhanced feeding in head and neck cancer patients undergoing major surgery may influence the postoperative outcomes by reducing the frequency rate of infections and wound complications.

Background Trauma is a leading cause of death worldwide and a major health problem of the modern society. Trauma systems are considered the gold standard of managing patients with trauma. An integral part of any trauma system is a trauma registry. In Europe, and particularly in Greece, trauma registries and systems are in an embryonic stage. In this study, we present an attempt to record trauma in Greece. Methods The Hellenic Society of Trauma and Emergency Surgery invited all the official representatives of the society throughout the country to participate in the study. In succeeding meetings of the representatives, the reporting form was developed and the inclusion criteria were defined meticulously. Inclusion criteria were defined as patients with trauma requiring admission, transfer to a higher level center, or arrived dead or died in the emergency department of the reporting hospital. All reports were accumulated by the Hellenic Trauma society, imported in an electronic database, and analyzed. Results Thirty-two hospitals receiving patients with trauma participated in the country, representing 40% of the country's healthcare facilities and serving 40% of the country's population. In 12 months time, (October 2005 to September 2006), 8,862 patients were included in the study. Of them, 66.9% were men and 31.3% were women. The compilation rate of the reporting forms was surprisingly high, considering that the final reporting form included 150 data points and that there were no independent personnel in charge of filling the forms. Conclusions Trauma registries are feasible even in health care systems where funding of medical research is sparse.

Aim of the study The aim of this study was to record and to evaluate the epidemiology of trauma in Greece and to assess the quality of management provided for trauma patients in the emergency department in Greek hospitals. Methods The Hellenic Society of Trauma and Emergency Surgery invited all the official representatives of the society throughout the country to participate in the study. The representatives that responded positively, met with the Board of the society in succeeding meetings to establish the reporting form and the inclusion criteria. Inclusion criteria were defined as trauma patients requiring admission, transfer to a higher level center or arrived dead or died in the emergency department of the reporting hospital. All reports were accumulated by the Hellenic Trauma society, imported in an electronic data base and analyzed. The design of the study was prospective and observational. Results In total 8862 patients were included in the study in 12 months time. Of them 68.7% ( n =6084) were male, aged 41.8±20.6 (mean±S.D.) and 31.3% were female ( n =2778), aged 52.7±24.1 (mean±S.D.). The mean duration of treatment in the emergency room department was 1h and 28min. Of the total number of patients, 2312 (26.1%) were initially assessed and managed by a specialist and 6249 (70.5%) were initially assessed and managed by a resident. Conclusions Data from this study show that there is substantial room for improvement in the patient care in the emergency department following trauma. Further evaluation will be required to identify particular management patterns that can be readily altered.

Heart failure (HF) is a major cause of perioperative morbidity and mortality in noncardiac surgery. Preoperative optimisation of these patients is, thus, of utmost importance. Levosimendan seems promising for patients undergoing cardiac surgery; however, its safety and efficacy in HF patients undergoing noncardiac surgery have not been evaluated.To evaluate the effects of prophylactic preoperative levosimendan administration on left ventricular function in HF patients undergoing noncardiac surgery.HF patients with ejection fraction30%undergoing elective noncardiac surgery in 2005 were included in this prospective study. Patients were admitted to our surgical intensive care unit one day preoperatively. Under continuous haemodynamic monitoring, the treatment protocol consisted of an initial loading dose (24 microg/kg) for ten minutes followed by a continuous 24-hour infusion (0.1 microg/kg/min) at the end of which patients underwent surgery. Echocardiography was performed before infusion (day 0) and on the 7th postinfusion day (day 7). Measurements included left ventricular ejection fraction (LVEF), velocity time integral(VTI), pre-ejection period (PEP), ejection time (ET),maximum (Pmax) and minimum P(min) transvalvular aortic pressure gradient, and maximum (Vmax) and minimum V(min) aortic velocity.Twelve consecutive patients were enrolled. Levosimendan resulted in a significant increase in LVEF,VTI, P(max), P(min), V(max), and V(min) (p0.01) and, moreover, a significant reduction in PEP, ET, and PEP/ET (p=0.04) on day 7 compared with day 0 values. No adverse reactions,complications or mortality occurred during 30-day follow-up.Prophylactic preoperative levosimendan treatment may be safe and efficient for perioperative optimisation of heart failure patients undergoing noncardiac surgery.

Background Apoptosis represents a physiological clearance mechanism in human tissues. The role of apoptosis has not been examined in normal lung cell populations, such as alveolar macrophages and polymorphonuclear cells. What is the percentage, as well as the role, of apoptosis in the alveolar microenvironment of the healthy human lung? Patients and methods Bronchoalveolar lavage was obtained from 21 volunteers without lung disease. The specimens were analyzed using: Annexin V binding, DNA laddering, light microscopy and immunohistochemistry for bcl-2 expression. Results Apoptosis of the total bronchoalveolar lavage cell population was 51.2%. Both alveolar macrophages and polymorphonuclear cells had a high apoptotic rate (62.1% and 48.3%, respectively) as determined by Annexin V binding. These findings were further confirmed using morphological criteria for apoptosis and gel electrophoresis for DNA fragmentation. In the majority of the individuals examined, (8 out of 21), the bcl-2 gene was expressed in the lymphocyte population mainly. Conclusions The percentage of apoptosis in lung cells of healthy humans is high. Apoptosis plays a key role in normal lung cell death. It appears to be the mechanism that opposes cell proliferation by eliminating, aged or damaged cells thus facilitating the process of lung remodeling.

Purpose Descending necrotizing anterior mediastinitis (DNAM) is a severe infectious disease with a very high mortality rate. The aim of this study was to define the impact of several clinical factors on survival. Patients and Methods Between 1985 and 2002, 27 patients were managed for DNAM, 11 with combined transthoracic mediastinal and cervical drainage (group A) and 16 with a less aggressive surgical approach, such as cervical drainage and transcervical mediastinal drainage (group B). The records of all patients were statistically analyzed for the impact of several clinical factors on survival. Results Although patients in group A were admitted to the hospital faster, treated with antibiotics as outpatients earlier, and operated on much sooner after hospital admission compared with the patients in group B, multivariate analysis revealed that early combined transthoracic mediastinal and cervical debridement and drainage was the only favorable factor for survival in patients DNAM patients (odds ratio = 9.99; 95% confidence interval = 1.02 to 97.49). Conclusions Less extensive surgical approaches (ie, thoracic drainage without cervical drainage or combined cervical and subxiphoid thoracic drainage) led to unsatisfactory results and high reoperation rates. In contrast, early, aggressive combined cervical and thoracic drainage proved to be an effective method for managing DNAM.

This prospective randomized study was conducted in order to define the contribution of the generated oxygen and nitrogen reactive species on postlobectomy morbidity and mortality.Between 2001 and 2003, 132 patients with non-small cell lung cancer (NSCLC) were prospectively studied. The patients were grouped according to one-lung ventilation (OLV) use or not and to the duration of lung's atelectasis. Group A included 50 patients with confirmed non-small cell lung cancer who were subjected to lobectomy without one-lung ventilation. Group B included 30 patients subjected to 60 min OLV. Group C included 30 patients subjected to 90 min OLV. Group D included 22 patients subjected to 120 min OLV. Preoperative, intraoperative and postoperative strict blood sampling protocol was followed. Malondialdehyde (MDA) plasma levels were measured. The groups were statistically compared for the occurrence of postoperative complications. OLV (groups B-D) along with other clinical parameters were entered in multivariate analysis as risk factors for complication development.Comparison of group A with groups B-D (OLV) documented significant increase (p0.001) of MDA levels during lung reexpansion. The magnitude of oxidative stress was related to OLV duration (group Dgroup Cgroup B, all p0.001). Univariate analysis disclosed a higher incidence of acute respiratory failure, cardiac arrhythmias and pulmonary hypertension in group D. Multivariate analysis revealed OLV as an independent risk factor for postoperative development of cardiac arrhythmias and pulmonary hypertension.Protracted (1h) OLV should be considered a potential cause for cardiovascular complications through the generation of severe oxidative stress due to lung reexpansion.

Complex thoracic injuries significantly alter the lung mechanics. There appears to be severe ventilation-perfusion inequality that is enhanced by the asymmetrical compliance of the injured areas. In cases of unilateral massive air leaks large tidal volumes are needed to deliver adequate air volume to the injured lung. In such cases, mechanical ventilation via a standard tracheal tube will direct a large fraction of the tidal volume to the less affected areas. An alternative means of ventilating these patients is the application of independent lung ventilation through a double lumen tracheal tube and the use of two separate ventilators. Two such cases are presented with emphasis given on the ventilatory and haemodynamic changes that were recorded.

About 1.7% of all abdominal wall hernias are incisional hernias and they have an expected incidence of 2–5% in uncomplicated abdominal operations which rises to 10%–15% in operations complicated by infection. It is estimated that incisional hernias will complicate 9% of all major abdominal operations and 30% of these hernias show thenselves within the rst 30 postoperative months (1, 5). Risk factors for hernia occurrence are infection and wound dehisence, length of the primary incision, and the use of corticoids during primary operation; in addition, obesity, postoperative cough or high intra-abdominal pressure, and technical errors all predispose to the development of a postoperative incisional hernia (3, 6). Large incisional hernias, apart from physical discomfort and deformity, are the cause of “Eventration Disease” according to Rives (8), which induces multiple symptoms from different systems. Important symptoms derive from pulmonary dysfunction, but symptoms from the gastrointestinal tract, skeletal pain and abdominal skin atrophy are not to be underestimated. Patients operated on for a large abdominal wall hernia face a high incidence of postoperative morbidity, mainly from pulmonary dysfunction, wound infection and the sudden rise in intra-abdominal pressure (10), despite the use of “progressive pneumoperitoneum”, which is a useful technique for preparing patients with large abdominal hernias. Many techniques have been used for repairing these large hernias but recurrence rates remain high, reaching 50% for the Mayo procedure (2, 7). The use of synthetic materials improved the recurrence rates but the results are not yet wholly satisfactory (4). Large incisional hernias pose a challenge in their repair technique and demand a thorough preoperative evaluation of the patient as regards respiratory function, prophylaxis of deep venous thrombosis and infection. Any postoperative complication might jeopardise the outcome. METHODS

Background and Objectives: Pancreaticoduodenectomy is still associated with high morbidity and mortality even though there has been significant progress in the field of pancreatic surgery and postoperative follow-up. The pancreatoenteric anastomosis, regardless of the technique used, is a major cause for both morbidity and mortality after Whipple procedure. To overcome all problems resulting from anastomotic leakage, we used external drainage of the pancreatic duct. Methods: In 24 patients who underwent pancreaticoduodenectomy in our Department from 1986 to 1995, a modification to the standard Whipple procedure was performed. Instead of pancreaticoenteric anastomosis, external drainage of the pancreatic duct remnant was performed. The pancreatic duct was intubated with a silastic tube, the external end of which was sutured to the skin. All patients received substitution therapy with pancreatic enzymes. Results: Mortality in our group of patients was 4%. No complications due to the external drainage of the pancreatic duct were reported, while no patient developed diabetes mellitus after surgery. Conclusions: External drainage of the pancreatic duct remnant can be used alternatively to pancreatoenteric anastomosis after pancreatoduodenectomy. The technique is safe and simple to perform and appears to reduce overall operative time. It may be an option for patients with significant comorbidity and/or intraoperative hemodynamic instability which mandates expeditious completion of the operation. J. Surg.

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. Language: en

Hypothesis Splenectomy is recognized as a cause of portal, mesenteric, and splenic vein thrombosis. The exact incidence of the complication and its predisposing factors are not known. Design Prospective observational cohort study. The median follow-up time of the patients was 22.6 months. Setting University surgical clinic in a teaching hospital. Patients A total of 147 consecutive patients who underwent splenectomy in a 4-year period were enrolled in the study. Interventions Preoperative and postoperative evaluation included ultrasonography with color Doppler flow imaging of the portal system, results of blood coagulation tests, fibrinogen levels, D-dimer levels, and complete blood counts. Operative sheets were recorded and reviewed. When portal system thrombosis (PST) was diagnosed, a complete control for acquired and congenital thrombophilia disorders was obtained. Main Outcome Measures Primary end points of the study were the assessment of the incidence of postsplenectomy PST and the identification of risk factors for its occurrence. Results Portal system thrombosis occurred in 7 (4.79%) of 146 patients who underwent splenectomy. The age, sex, type or length of the operation, and use of preoperative and postoperative thromboprophylaxis with low molecular weight heparin did not prove to be significant factors in the occurrence of PST. Platelet count of more than 650 × 10 3 /μL and greater spleen weight (>650 g) was associated with the development of PST ( P = .01, P = .03). Normal D-dimer levels on diagnosis of the complication showed a negative predictive value of 98%. Two of the affected patients were diagnosed with thrombophilia disorders. In a median follow-up period of 22.6 months, no other case of PST was recorded. Conclusions Postsplenectomy PST occurs in approximately 5% of patients. Possible risk factors are thrombocytosis, splenomegaly, and congenital thrombophilia disorders.

A 60-years old male was admitted to our department for investigation of constipation and hypogastric discomfort intensified during defecation of a few weeks duration. The cause proved to be a rectal carcinosarcoma that was treated by abdominoperineal resection and postoperative chemo-radiotherapy. The patient died 6 months later due to hepatic failure, showing evidence of disseminated disease. In general colonic carcinosarcomas constitute a rare category of malignant neoplasms whose nature is still incompletely understood. No specific treatment guidelines exist. Surgery is the mainstay of treatment and regardless of the addition of adjuvant therapy the prognosis is very poor. Systematic genetic analysis may be the clue for understanding the pathogenesis of these mysterious tumors.

The aim of this study was to evaluate the safety, efficacy, and effects of administration of very high doses of norepinephrine (4 microg kg(-1) min(-1)) in catecholamine-resistant septic shock. We reviewed the charts of all patients with nonresponding to commonly used norepinephrine doses (or = 4 microg kg(-1) min(-1)) septic shock from January 1999 to December 2002 in our Surgical Intensive Care Unit. All patients were treated with high norepinephrine doses (4 microg kg(-1) min(-1)), after initial resuscitation, so as to achieve a mean arterial pressure higher than or equal to 65 mmHg. During this 4-year period, 12 consecutive patients with catecholamine-resistant septic shock were included in our study. When compared with the values obtained prior to the administration of very high norepinephrine doses, the values of mean arterial pressure (p = 0.003) and systemic vascular resistance (p = 0.002) significantly increased after the administration of such doses, and additionally, lactate concentrations (p = 0.003) decreased. In contrast, no significant changes were observed regarding mean central venous pressure, pulmonary capillary wedge pressure, and pulmonary arterial pressure. Administration of high norepinephrine doses in our patients resulted in a survival rate of 33.4%. Management of catecholamine-resistant septic shock patients poses a challenging problem. Administration of very high norepinephrine doses is safe and effective and may improve survival of these patients with otherwise extremely high mortality rates.

Forty-two patients with necrotizing soft tissue infection are reviewed. Bacterial culture revealed between two and seven types of micro-organism in each patient. All patients were treated with radical surgical debridement and a combination of antibiotics. In 30 patients, early diagnosis and treatment resulted in only two deaths. Delayed surgical intervention in 12 patients transferred from outside hospitals was followed by nine deaths. Predisposing factors and site of infection did not affect outcome. Of 26 patients with systemic manifestations of sepsis, 16 survivors responded well to initial surgical debridement.

Background Quality assessment of any trauma system involves the evaluation of the transferring patterns. This study aims to assess interfacility transfers in the absence of a formal trauma system setting and to estimate the benefits from implementing a more organized structure. Methods The 'Report of the Epidemiology and Management of Trauma in Greece' is a one year project of trauma patient reporting throughout the country. It provided data concerning the patterns of interfacility transfers. We compared the transferred patient group to the non transferred patient group. Information reviewed included patient and injury characteristics, need for an operation, Intensive Care Unit (ICU) admittance and mortality. Analysis employed descriptive statistics and Chi-square test. Interfacility transfers were then assessed according to each health care facility's availability of five requirements; Computed Tomography scanner, ICU, neurosurgeon, orthopedic and vascular surgeon. Results Data on 8,524 patients were analyzed; 86.3% were treated at the same facility, whereas 13.7% were transferred. Transferred patients tended to be younger, male, and more severely injured than non transferred patients. Moreover, they were admitted to ICU more often, had a higher mortality rate but were less operated on compared to non transferred patients. The 34.3% of transfers was from facilities with none of the five requirements, whereas the 12.4% was from those with one requirement. Low level facilities, with up to three requirements transferred 43.2% of their transfer volume to units of equal resources. Conclusion Trauma management in Greece results in a high number of transfers. Patients are frequently transferred between low level facilities. Better coordination could lead to improved outcomes and less cost.
