After careful history and physical examination the diagnosis of neuropathicpain was established. The pain did not relieve with the pharmacological treatment, so superior hypogastric ganglionblock was performed. The patient remained pain free for a week, after which the complaints recurred. Then an epiduralcatheter was attempted twice but abandoned after two failed attempts. The catheter perforated the dura mater leadingto flow of CSF. After a few hours the patient developed a complaint of severe headache. The patient was hospitalisedand intravenous NSAID’s were started. However, the headache did not relieve, so CT scan brain was ordered, whichdetermined the presence of pneumocephalus. The patient was offered symptomatic...

Two hundred and forty patients aged 5 to 12 years undergoing circumcision were included in the study. Following induction, caudal 0.125% levobupivacaine 0.5 ml/kg was given after adding 7.5, 10 or 15 μg/kg morphine. The postoperative incidence of vomiting was 5%, 12.5% and 17.5% in the groups 7.5, 10 and 15 μg/kg morphine, respectively ( P=0.012, 7.5 versus 15 μg/kg groups). Five percent of the 7.5 μg/kg group and none of the patients in the other groups required paracetamol within the first 12 hours, and there was a significantly greater need for rescue paracetamol over the 24 hours in the 7.5 group versus the 15 μg/kg group ( P=0.013). Postoperative analgesic durations were long and did not differ betw...

Out of this research a number of promising algorithms have surfaced. Inductive learning algorithms are domain independent. In principle, they can be used in any task involving classification or pattern recognition. In this paper a number of applications of RULES family of induction algorithms to visual inspection are presented. The main advantages of using induction for visual inspection are: (a) The systems does not suffer from orientation problem which is very important for digital image processing. (b) The pattern does not have to be stored in the memory in graphics form because they are represented by rules. This saves memory space. (c) The decision can be reached in short time because the number of conditions in each rule and the total number of rules are not big. (d) It is easy to develop a software and design a hardware for these systems as they are not complicated.

The primary purpose of this study was to determine the sufficiency for anesthesia of distal nerve block without the need for deep sedation or general anesthesia. The secondary purpose was to compare block performance times, block onset times, and patient and surgeon satisfaction. Patients who underwent hand surgery associated with the innervation area of the radial and median nerves were included in the study. Thirty-four patients who were 18-65 years old and American Society of Anesthesiologists grade I-III and who were scheduled for elective hand surgery under conscious nerve block anesthesia were randomly included in an infraclavicular block group (Group I, n=17) or a radial plus median block group (Group RM, n=17). The block performance time, block onset time, satisfaction of the patient and surgeon, and number of fentanyl administrations were recorded. The numbers of patients who needed fenta...

Materials and Methods: In group 1, periprostatic nerve block was applied to both neurovascular areas with 2% lidocaine (5 ml) in an isotonic solution (5 ml). In group 2, the combination of 2% lidocaine (5 ml) and 5mg/ml bupivacaine (5 ml) was used for the PPNB. Results: In the first 30 minutes the mean VAS scores of groups 1 and 2 were 2.1 ± 0.2 and 1.2 ± 0.1, respectively (p = 0.002). VAS scores of group II determined at 1, 2, 4, 6, and 8 hours after the biopsy were significantly lower since it was (p < 0.05). Conclusion: While periprostatic nerve block for late phase pain control, applying a combination of a long-acting local anesthetic, such as bupivacaine, is effective in terms of pain control and patient comfort.

The Hit-Point trial was a multicenter, randomized, controlled trial of enhanced HF education with a 6-month telephone follow-up program (EHFP) vs routine care (RC) in patients with HF and reduced ejection fraction. A total of 248 patients from 10 centers in various geographical areas were randomized: 125 to EHFP and 123 to RC. Education included information on adherence to treatment, symptom recognition, diet and fluid intake, weight monitoring, activity and exercise training. Patients were contacted by telephone after 1, 3, and 6 months. The primary study endpoint was cardiovascular death. Although all-cause mortality didn't differ between the EHFP and RC groups (p=NS), the percentage of cardiovascular deaths in the EHFP group was significantly lower than in the RC group at the 6-month ...

CSLS has two components, an induction algorithm to carry out inductive learning and a multi-layer perceptron (MLP) to implement neural learning. The paper outlines the operation of the components of CSLS and describes how the combined system is designed to utilise the individual strengths of inductive and neural learning to the best advantage. The paper gives the results of evaluating CSLS on the IRIS data and Breast-Cancer-Wisconsin-data classification problems. These clearly demonstrate the main benefit of the symbiotic combination: the combined system performs better than either of its components.

The purpose of this study is to evaluate the long-term effects of thoracal epidural levobupivacaine and intravenous dexketoprofen analgesia formed pre-emptively on the wound site pain after major thoracotomy operations. This randomised, prospective and double-blind study was performed with 60 patients undergoing thoracic surgery. Patients were divided into three groups; Control Group (Group C), Pre-emptive Epidural Group (Group PE) and Pre-emptive Dexketoprofen + Epidural Group (Group PED). Patients in the Group C did not receive epidural analgesics and i.v. dexketoprofen before and during the operation. 10-15 ml 0.125% levobupivacaine was given to cases in Group PE pre-emptively through epidural catheter before the anesthesia induction. The cases in Group PED were given 10-15 ml 0.125% epidural levobupivacaine and 50 mg dexketoprofen with i.v. infusion pre-empt...

In order to achieve this aim, a "Computer Self-efficiency Scale" used in educational sciences was selected and this scale was applied in a study group. Data was analyzed using descriptive statistics (ttest and analysis of variance), and the data mining techniques of decision tree, dependency networks and clustering. The descriptive statistics used were calculated not using common statistical software packages, but by running a program written in Delphi 2009 programming language on Microsoft SQL Server 2008. Microsoft SQL Server 2008 was directly used for the data mining techniques of dependency networks and clustering. Some of the findings of the research, which cannot be obtained by common statistical techniques but can be obtained by data mining methods, were as follows: "those who think they are competent with computer terms and concepts believe they have a special talent in using computers" ; "those who believe they have a special talent in using computers feel as if the computer is part of their body", and "students who have been using computers for more than six years believe they have a special talent in using computers".

A total of 60 patients scheduled for elective open nephrectomy under general anesthesia were included. All patients received Patient-controlled IV analgesia with fentanyl postoperatively. Patients were randomly allocated into three equal groups: The fentanyl group received 100 mL of IV normal saline as a placebo, with the first dose ending 30 min before intubation. In paracetamol group, IV 1 g paracetamol was given to the patients 30 min after extubation with repeated doses every 6 h totally 4 times a day. In preemptive paracetamol group, patients received IV 1 g paracetamol every 6 h, with the first dose ending 30 min before intubation. Postoperative cumulative fentanyl consumption for 24 h was significantly higher in the fentanyl group (1009 ± 139.361 μg) than those of paracetamol (752.25 ± 11...

Between October 2012 and April 2013, 189 consecutive patients undergoing percutaneous coronary intervention electively or due to acute coronary syndrome were enrolled. There were 96 patients in the sandbag group and 93 patients in anjiobelt group. Manual compression was applied to the femoral artery until reaching primary homeostasis. Then, a 4-5 kilogram sandbag or anjiobelt was placed. Mobilization was allowed in case of need in the anjiobelt group. Twenty-four hours after the procedure, superficial bruising in the femoral region, hematoma, pseudo-aneurysm, and arteriovenous fistula, as femoral artery complications, were noted using Doppler ultrasound. Hematoma occurred more frequently in the sandbag group. Hematoma of <1 cm developed in 52 pati...

A total of 439 patients (351 males, 88 females; mean age 57+/-12 years) with ST-elevation AMI were interviewed within 48 hours of hospitalization. Patients were pain-free and hemodynamically stable at the time of interview. Data were collected on the time from the onset of chest pain to hospital admission and on sociodemographic and clinical characteristics. The patients were evaluated in two groups according to the place to which the first presentation was made, i.e., a local clinic/small hospital (clinic group: n=209, 47.6%) or our tertiary fully equipped cardiovascular center (hospital group: n=230, 52.4%). The median and mean delay times were 70 min and 185.2+/-334.8 min, respectively. Of the study group, 136 patients (31%) arrived within 60 minutes after the onset of symptoms. The median delay time was significantly longer in the clinic group (120 min vs 60 mi...

Regional anaesthesia techniques are usually preferred in high-risk patients due to some advantages, such as the maintenance of cardiovascular stability and early postoperative mobilisation. This case presents the anaesthetic approach in a 55-year-old male patient with low ejection fraction that underwent hip fracture surgery. In this present case, continuous spinal anaesthesia with low-dose hyperbaric bupivacaine provided safe and effective anaesthesia during surgery with minimal haemodynamic changes and adequate analgesia during the first 24 hours after surgery.

The purpose of this study was to evaluate the anaesthesia methods employed in our clinic in the last decade (2003-2012). Methods: Records of caesarean operations performed between 2003-2012 in the Anaesthesia department of Atatürk University Medical Faculty and stored in the hospital computer system were examined. The annual distribution of methods of anaesthesia in operations was analysed. Results: During 2003-2012, 9049 caesarean operations were performed in our clinic. General anaesthesia was used in 45% of operations and regional anaesthesia in 54%. Whereas the rate of regional anaesthesia in 2003 was 34%, this increased to 69% in 2012. The most commonly used method of regional anaesthesia was spinal anaesthesia (34%) in 2003, and spinal anaesthesia (41%) and combined spinal-epidural anaesthesia (27%) in 2012. Conclusion: The most commonly used anaesthesia technique for caesarean operations in our clinic between 2003-2012 was spinal anaesthesia. The most widely used regional anaesthetic method in our clinic was spinal anaesthesia. A significant increase in the use of the combined spinal-epidural anaesthetic technique occurred in the last two years of the study period.

It is concerned with developing methods for exploring the unique types of data that come from educational environments. Its goal is to better understand how students learn and identify the settings in which they learn to improve educational outcomes and to gain insights into and explain educational phenomena. Educational information systems can store a huge amount of potential data from multiple sources coming in different formats and at different granularity levels. Each particular educational problem has a specific objective with special characteristics that require a different treatment of the mining problem. The issues mean that traditional DM techniques cannot be applied directly to these types of data and problems. As a consequence, the knowledge discovery process has to be adapted and some specific DM techniques are needed. This paper introduces and reviews key milestones and the current state of affairs in the field of EDM, together with specific applications, tools, and future insights.
