Background: The causes of acute pancreatitis are well known, and although enzymatic injury is the main factor in its development, pancreatic ischemia due to profound hypoperfusion in cardiogenic or hypovolemic shock patients can be an important etiological factor. The aim of our study was to analyse the histological alterations of the pancreas in patients dying after shock, to study the presence and severity of pancreatic injury.
Material and methods: We studied the morphological alteration of the pancreas, in patients who died after cardiogenic or hypovolemic shock, hospitalized in intensive care units in the County Emergency Hospital Tîrgu Mureș, between 2007–2009.
Results: We examined the structure of the pancreas of 117 patients, 20 showed acute hemorrhagic pancreatic necrosis on autopsy. None of the patients showed typical clinical and laboratory signs for acute pancreatitis. The common findings in these patients were prolonged and severe hypotension, leucocytosis, hyperglycemia and hypocalcemia.
Conclusions: Pancreatitis can occur in patients with shock, due to ischemic injury of the pancreas. It is difficult to diagnose it because clinical signs are altered by the severity of the underlying disease or by analgo-sedation commonly used in intensive care units. We therefore recommend to consider the possible development of acute pancreatitis in patients with shock, in patients with prolonged hypotension, leucocytosis, hypocalcemia, even in the absence of characteristic clinical symptoms and hyperamylasemia.

Background: Organ transplantation is a modern treatment for many patients, however current organ shortage determines the need to identify strategies to eliminate barriers and increase organ donation rate. Aim of the study is to determine present and future health care professionals’ attitude and methods of further knowledge acquisition on the topic of organ donation and transplantation.
Material and method: We performed a cross-sectional survey in a study population consisting of preclinical medical undergraduates and of general practitioner doctors, the self administered questionnaires were anonymously statistically analyzed, the association between variables was considered significant for values p <0.05.
Results: One-hundred forty students and 48 doctors participated in our study, both groups showed positive attitude towards organ donation, 81.4% and 68.8% respectively were willing to donate own organs after death. Previous family discussions determined significant change of attitude among students but not within the group of doctors. Formal earlier education on the topic of transplantation was reported by 25% of the students but by none of the doctors. Preferred information channels are medical journal articles in both groups (37.9% vs. 35%), additionally medical students would prefer lectures and seminars while doctors would like to receive information during conferences and congresses. Internet is chosen (30–32%) over classical mass media.
Conclusions: although health care professionals have a natural inclination towards accepting donation and transplantation, providing information is essential in structuring their attitude in the way of promoting an environment that has a positive influence on organ donation rates.

Background: Occupational stress afflicts not only job performance, but also the physical status and the health of the working human being. Thus, methods to analyze the level of stress and burnout by laboratory measurements and different types of questionnaires were developed during the last years.
Aim: To determine the relationship between salivary cortisol variations and the individual self evaluation performed by physicians in several medical fields: general surgery, intensive care, internal medicine.
Material and method: A self assessment survey was undertaken by physicians in three specialties, investigating the place doctors find themselves in the collectivity, their integration and interpersonal relationships – all contributing to a burn-out potential inventory score, the BPI. The BPI score was correlated with the cortisol level found in 3 samples of saliva collected at awakening, immediately after the maximum stress of the day and at night, before sleeping.
Results: We found significant variations of the cortisol level between the early morning salivary level at awakening and the climax of the stress. There was a linear correlation between the maximal cortisol level and the BPI score.
Conclusion: Salivary cortisol, well correlated with serum levels is a consistent marker of the stress and the intensity of the reactivity to stress. Thus we promote it as a feasible, accessible and low cost measurement of the reactivity to stress, both for the individual and the professional group.

Introduction: The BCR-ABL fusion gene [t(9;22) (q34;q11)] occurs in 3–5% of pediatric acute lymphoblastic leukemia (ALL) and predicts a very poor prognosis.
Material and methods: 2 ml samples of bone marrow (BM) and peripheral blood (PB) in EDTA tubes from 24 ALL patients were examined in the molecular biology laboratory of our university with quantitative real-time PCR (qRT-PCR) method for BCR-ABL gene expression. Prognostic factors, like age, leucocyte count, lymphoblast morphology and immunology, absolute lymphoblast count on day 8, remission status on day 33 as well as treatment results were recorded from every patient.
Results: All 24 qRT-PCR analysis for major and minor BCR-ABL gene expression from BM and PB were negative. Immunophenotyping performed in 25 patients revealed common B ALL in 12 patients, T-cell immunology in 3 and pre-B immunophenotype with aberrant myeloid marker expression and/or CD10 negativity in 11 patients. L1 morphology appeared in 85.7% of the pre-B ALL cases, while other immunophenotypes were more likely associated with L2 cytology (62.5%) (p=0.033). Early cortisone response was favourable in 22 patients, all 26 patients achieved complete remission on day 33. Common B immunophenotype was associated with lower WBC (mean 37,770, median 8,200) than other immunophenotypes (WBC mean 63,783, median 50,680).
Conclusions: A new method, the qRT-PCR test was introduced in the investigation of pediatric ALL in our university from 2010. We found a statistically significant correlation between L1 blast morphology and common B immunophenotype. Poor cortisone response was found more frequently in T-cell ALL and pre-B ALL with aberrant myeloid markers or CD10 negativity. All our patients achieved complete remission on day 33. Lower WBC count at presentation was associated with L1 morphology and pre-B immunophenotype.

Objective: The aim of the study was to analyze in parallel the 6th and the newest 7th AJJCC/UICC (American Joint Committee on Cancer/ International Union Against Cancer) staging system in order to highlight changes brought about the new staging system.
Methods: We analyzed data obtained retrospectively from 134 hospitalized patients diagnosed with gastric carcinomas, who underwent surgery at the Surgery Clinic of the Emergency County Hospital of Tîrgu Mureş, Romania between 2008–2010. The data have been obtained from histopathology reports, and the analyzed parameters were the following: age, gender and pTNM staging. For all cases included in the study restaging was performed according to the 7th AJJCC/UICC staging system. For statistical analysis we used GraphPad InStat software.
Results: 71.66% of cases were adenocarcinomas, 7.46% mucinous adenocarcinoma, 14.17% signet ring cell carcinoma, and 6.71% undifferentiated carcinoma. The signet ring cell carcinomas predominated before 65 years of age (p=0.003). Compared to the 6th staging system, in the new system, pT2 percentages decreased significantly from 38.8% to 6.71%, and pT4 increases from 11.19% to 55.97% (p<0.0001).The pN3 cases increased from 20.9% to 45.52%, because all cases classified as pN2 in the old staging system, become pN3 in the new system. Some of pN1 cases turned into pN2 in the new system (p=0.004). The stage IV cases also decreased from 29.85% to 14.94%, due to regrouping of stage III.
Conclusions: There are significant changes between the two staging systems. The new staging system aims to achieve a better postoperative follow-up.

Objective: We tried to correlate the clinico-pathologically features of colorectal cancer (CRC) to expression of eight immunohistochemically (IHC) markers and microsatellite instability (MSI) in order to realyze a molecular subdivision of these tumors.
Methods: 300 CRC, surgical specimens, were statistically and IHC evaluated. MSI status was analyzed in 52 cases, with Real Time PCR, melting point analysis. The following IHC markers have been used: CD8, E-cadherin, HER-2, p53, Ki67, bcl-2, MLH-1, CEA. The molecular phenotypes have been reported to the node status (pN) and MSI.
Results: Based on statistically analyses, we revealed that CEA and Ki67 were not prognostic factors. MLH-1 may indicate the MSI status and the number of tumor inflitrated lymphocytes stained with CD8 seems to be higher in the MSI cases and tumors of the proximal colon. HER-2 expression was correlated to number of the lymph node metastatses and bcl-2 was negative is most of the CRC diagnosed in advanced stages.
Conclusions: The CRC may be subdivided in six molecular prognostic groups, the best prognosis showing the MSI/p53-/bcl-2+/HER-2- and the worst MSS/p53+/bcl-2±/HER-2+. These molecular subdivision may be the basis for targeted therapy in node negative CRC.

Aim: We studied in a hemodialysis (HD) population the correlations between bone metabolism markers measured by DEXA compared with other bone markers: serum calcium, serum phosphate, serum iPTH level and the inflammatory status, known as high risk for morbidity in HD patients which has not been studied yet.
Method: Twenty-seven patients from a hemodialysis unit were included in the study. The following parameters were measured: serum calcium (Ca), serum phosphate (P), total alkaline phosphatase (AP), intact parathormon level (iPTH) as bone metabolism markers and fibrinogen and C reactive protein (CRP) as inflammatory markers. Osteodensitometry was measured with DEXA technique and T-score was recorded. Statistical data were analyzed with the program Excel 2007 and mean, SD, Pearson’s correlation coefficient r and χ2-test were calculated.
Results: Significant correlations were found between serum Ca levels and P (p=0.002), AP (p=0.002) and T-score (p=0.0003). Also there was a correlation between CRP and phosphate (p=0.029) and CRP and fibrinogen (p=0.037). Calculating the correlation coefficient r, the significant correlation threshold was relevant to Ca and AP (r=0.33, p <0.05), Ca and BMD (r=0.31, p <0.05), P and BMD (0.30, p <0.05), P and fibrinogen (r=0.6, p <0.01).
Conclusions: In HD patients, CRP is correlated with bone metabolism, in the absence of infection. Serum phosphate is the only marker correlated
with bone markers, inflammatory markers and T-score for osteodystrophy, being an important tool for the future prognostic of these patients.

Objective: To analyze the results of using S53P4 as a bone graft substitute in a series of orthopaedic procedures.
Methods: We included a number of 9 patients in our study between July 2010 and March 2011. There were 4 cases of cystic or tumoral lesions, 2 revision total hip replacements, 1 primary hip replacement, 1 calcaneus fracture and 1 case on femoral supracondylar non-union. All were treated using bioactive glass as a bone substitute alone, or in conjunction with morselized allografts and autogenous bone grafts. Patients were evaluated clinically and radiologically at 1, 3 and 6 months after surgery.
Results: We found good results on clinical evaluation and radiological evaluation showed signs of graft osteo-integration and incorporation of the synthetic bone substitute in all cases.
Conclusions: Our preliminary results have shown that bioactive glass (S53P4) can be successfully used as a bone substitute material in all of the presented pathological conditions. We believe that this type of synthetic bone substitute will become more popular in the future, due to its special properties.

Introduction: Arterial hypertension is defined as systolic or diastolic blood pressure measurements higher than 95 age-gender-height percentile of the adopted reference values. Angiotensin-converting enzyme (ACE) is a component of renin-angiotensin system. ACE insertion/deletion (I/D) gene polymorphisms have been associated with the risk of various cardiovascular anomalies.
Aim: The purpose of our study was to assess the possible association of ACE I/D polymorphism gene and secondary hypertension in children.
Material and method: We genotyped 40 healthy and 38 hypertensive children and adolescents. The ACE I//D gene polymorphism was determined by polymerase chain reaction (PCR) and restriction fragment length polymorphism technique utilizing specific primers. We compared the distribution of ACE I/D genotypes in the two study groups.
Results: The results of the study showed that the frequency of I/D ACE genotype distribution in patients with hypertension (DD = 18.42%,
ID = 68.42%, II = 13.16%) did differ significantly from genotype distribution in controls (DD = 47.5%, ID = 42.5%, II = 10%), and the DD genotype was not associated with secondary hypertension.
Conclusion: In conclusion we demonstrate that ACE gene polymorphisms are genetic markers for secondary arterial hypertension in children.
