However, the NLR’s role in mortality prediction was poorly evaluated in the literature.Patients and Methods: We performed a retrospective, cross-sectional study to analyze the role of NLR0 (at admission) and NLR48 (at 48 hours) in acute pancreatitis as compared with CRP, BISAP, SOFA, and modified CTSI (mCTSI) for the prediction of mortality and severe acute pancreatitis (SAP) in patients admitted into the Emergency Clinical County Hospital of Craiova during 48 months. The primary assessed outcomes were the rate of in-hospital mortality, the rate of persistent organ failure, and ICU admissions. We analyzed mortality prediction for all acute pancreatitis, for biliary, alcoholic, and hypertriglyceridemic acute pancreatitis, for severe forms, and for patients admitted to the ICU.Results: A total of 725 patients were selected; 42.4% had biliary acute pancreatitis, 27.7% had alcoholic acute pancreatitis, and 8.7% had hypertriglyceridemia-induced acute pancreatitis. A total of 13.6% had POF during admission. The AUC for NLR48 in predicting mortality risk and SAP was 0.81 and 0.785, superior to NLR0, CRP48, and mCTSI but inferior to BISAP and SOFA scores. The NLR48/NLR0 ratio did not add significantly to the accuracy. NLR0 and NLR48 performed poorly for mortality prediction in severe forms and in patients admitted to the ICU. NLR48 has good accuracy in our study for predicting death risk in biliary and alcoholic acute pancreatitis but not in hypertriglyceridemic acute pancreatitis.Conclusion: NLR48 was a good indicator in predicting mortality risk and severe forms in all patients with acute pancreatitis, but not of death in SAP and in patients admitted to ICU, with good accuracy for predicting death risk in biliary and alcoholic acute pancreatitis but not in hypertriglyceridemic acute pancreatitis.Keywords: acute pancreatitis, severe acute pancreatitis, neutrophil–lymphocyte ratio, BISAP score, SOFA score, C-reactive protein

The aeration process for a biological wastewater treatment plant is the main electrical energy consumer. The paper presents an innovative aeration system to be used in Mobile Bed Biofilm Reactors. It is known that this technology uses metallic air diffusers with medium bubbles, so an increased air quantity is required. The authors propose an innovative aeration system based on metallic diffusers with micro-orifices equipped with an ultrasound anti-clogging system. In this way smaller quantities of air will be introduced inside the bioreactors. [ABSTRACT FROM AUTHOR]

Colorectal cancer is the third most often encountered type of cancer and represents the third leading cause of cancer related deaths, on both sexes. One of the most important prognostic parameters is the tumor's stage at the time of the diagnosis. T4 cancers represent advanced tumors associated with penetration of the visceral peritoneum (T4a) and/or direct invasion in adjacent structures (T4b). Preoperative diagnosis is influenced by the inability of the existent imaging modalities to accurately differentiate the true invasion from the simple, inflammatory adherence to the neighboring structures. As a consequence surgical treatment must follow the principle of en bloc resection; however the ability of achieving an R0 resection depends on the tumor location, invaded organ, and the type of the surgical procedure required. Neoadjuvant treatment for advanced colon cancer it may be very difficult to be applied. This review is focused on preoperative workup, therapeutic strategies and subsequent results in advanced T4 colon cancers. [ABSTRACT FROM AUTHOR]

The early diagnosis of esophageal cancer is necessary for improving the surviving of patients with this disease. To ensure an accurate staging, there are necessary imaging tests to establish the local and regional extension, as well as excluding the metastases. Computed tomography (CT), endoscopic ultrasonography (EUS), and positron emission computed tomography (PET-CT) constitute standard methods for esophageal cancer staging. These techniques are complementary; using only one of these tests is not suitable for correct staging. The role of EUS has improved the doctors' ability to evaluate and select the patients to undergo surgery, radiotherapy, or chemotherapy. [ABSTRACT FROM AUTHOR]

Identification of sentinel lymph node (SLN) in colon cancer is very important in order to increase the accuracy of lymph node staging. The number of examined lymph nodes represents a significant predictor of survival. This study aims to show the importance of SLN histological and immunohistochemical examination in adjuvant oncological treatment. The study includes 23 patients with colon cancer (44% women and 56% men) who came in our clinic for surgical intervention. In all cases, the SLN was identified and prepared for histological examination. In 13 of the cases, micrometastases were found on haematoxylin-eosin (HE) staining, there were 5 cases with positive immunohistochemistry using antibodies anti-p53, anti-VEGF-C, anti-CD34, and 5 cases with SLN negative both for HE and immunohistochemistry. Altogether we had a detection rate of 92%, an accuracy of 78,2%, a sensitivity of 90%, a false negative rate of 10% and a negative predictive value of 71,4%, good values according to the literature. Four (17,3%) patients had micrometastases exclusively in the sentinel lymph node, after performing additional histological examination, using multilevel section and immunohistochemistry. After assessing the SNL on our patients, we concluded that it is a reproducible practice for lymph node analysis. [ABSTRACT FROM AUTHOR]

Purpose: This study aims to evaluate intratumoral microvessel density in rectal carcinoma cases with different histopathological type (adenocarcinoma and mucinous carcinoma) and different preoperatory neoadjuvant radiotherapy status (irradiated / non-irradiated), thus analyzing any possible statistical correlation between these parameters. Material and methods: Our prospective study consists in standard immunohistochemistry procedures using CD34, CD31 and CD105 antibodies, which were performed on 25 samples of rectal carcinoma, in order to determine intratumoral microvessel density. Results: The 25 case study group was divided either by histopathological type or by prior radiotherapeutical treatment as follows: 9 cases of mucinous carcinoma versus 16 cases of adenocarcinoma and 13 cases of rectal cancer that have not received neoadjuvant radiotherapy versus 12 cases of rectal cancer with preoperatory radiotherapy. Conclusions: The number of intratumoral microvessels is higher in non-irradiated rectal tumors and in adenocarcinomas, this remark being statistical significant (with only one exception - CD34 staining in non-irradiated versus irradiated tumors) for all types of vessels (new-grown and mature). This result is due to the benefic effect of neoadjuvant radiotherapy on decreasing angiogenic activity, thus having an important prognostic value for rectal cancer. [ABSTRACT FROM AUTHOR]

Spasticity represents an important feature of the upper motoneuron syndrome (UMNS). The clinical signs, such as the abnormal movement models, the unwanted muscular co-contractions, the muscular and joint rigidity with a consecutive deformity can be signs of spasticity and, also of upper motoneuron lesion. The different therapeutic options applied in the management of spasticity are a basic component of UMNS treatment scheme. This article presents the main kinesiotherapeutic procedures used in spasticity therapy. [ABSTRACT FROM AUTHOR]

The aim of the study was to observe the differences between the expression of c-abl inside the tumor and at the resection limit at patients with gastric cancer. We use for our study 20 patients with gastric cancer with ages between 49 and 79 years with a median of 65 years, with a repartition on sexes 12 men and 8 women. We collected after the surgical intervention two samples of tissue: one sample from the tumor process and another sample from the gastric apparent normal tissue, as far from the tumor as it was possible. Quantitative real-time polymerase chain reaction was used to determine c-abl gene expression. Considering gastric cancer and the c-abl gene expression, c-abl is down regulated inside tumor cells comparing to the normal gastric tissue from de resection limit. This underlines the role of c-abl in normal tissue growth and its ability of inducing apoptosis when alteration of DNA occurs, as a result of different agents as stress, ionizing radiations. Down-regulation or loss of expression of c-abl is a fundamental event that leads at tumor apparition and progression. [ABSTRACT FROM AUTHOR]

We examined the efficacy of physical therapy and adjunctive botulinum toxin type A (BTX-A) injections in the treatment of cervical headache. We performed a doubleblind, randomised, placebo-controlled study over a 12-week period in a university clinic outpatients department. A total of 33 patients with cervical headache, diagnosed according to International Headache Society classification were enrolled. All patients received standardized physical therapy over a three-week period. Patients were randomised to receive either BTX-A (Botox) or placebo. The BTX-A group received a total dose of 90 mouse units (mu) BTX-A at six trigger points while the placebo group received saline. Pain characteristics were reported in a headache diary. Tenderness in the neck muscles, the sagittal range of motion and biofeedback measurement were also documented. Both groups showed significant improvement in terms of headache severity (p<0.05), number of headache-free days (p=0.005) and number of headache hours per day (p<0.05). Trends towards an increase in the number of headache-free days and a decrease in headache hours per day were observed in the BTX-A group. No major side effects were observed. Physical measures and BTX-A injections are safe and effective in the treatment of cervical headache. [ABSTRACT FROM AUTHOR]
