RESUMEN
Pancreatic cancer is one of the most aggressive cancer due to the late diagnosis and failure to respond to the treatment despite advances in tumor biology and the development of new cancer therapeutic strategies. It has been reported that these characteristics of pancreatic cancer originate from cancer stem cells within the tumor mass. It has also been reported that Fentanyl is a fast-acting analgesic that binds to the mu-opioid receptors and some other mu-opioid receptors are involved in this cancer process. In this study, we determined the effect of Fentanyl on PANC-1 cells, by assessing the gene expression of cancer stem cell marker genes (Nanog, Oct4, and Sox2) and apoptosis-related genes (BAD, Bax, Bcl-2, and p53) by Quantitative RealTime PCR. The number of cancer stem cells was determined by Flow Cytometry. The results of our study showed that Fentanyl administration decreased the number of cancer and cancer stem cells in the PANC-1 cell population, decreased the gene expression of stem cell marker and increased the expression of apoptosis-related genes. These results indicate that Fentanyl, which is used routinely in the pain palliation of pancreatic cancer, can be considered as an option in the treatment of pancreatic cancer.

Objectives: In this study, we aimed to investigate the therapeutic effects of magnesium sulfate (MgSO4) and dexmedetomidine (dex) in a model of acute lung injury (ALI). We determined whether concomitant administration decreased the inflammatory effects of hydrochloric acid (HCl)-induced ALI in a synergistic manner. Materials and Methods: In this study, 42 Sprague-Dawley rats were randomized into six groups: Group S (saline), Group SV (saline + mechanical ventilation), Group HCl (HCl), Group Dex (Dex), Group Mag (MgSO4), and Group DM (Dex + MgSO4). All groups except Group S were mechanically ventilated prior to HCl-induced ALI. Saline or HCl was administered via tracheostomy. Prior to treatment, HCl was administered to Group HCl, Group Dex, Group Mag, and Group DM to induce ALI. Dex and MgSO4 were administered intraperitoneally. The rats were monitored for 4 h after treatment to measure oxidative stress parameters in blood, and prolidase enzyme activity. Lung tissue damage were determined via histopathology. Results: A significant increase in heart rate and rapid desaturation was observed in HCl-administered groups. Treatment administration decreased the pulse values. Increased saturation values and decreased oxidative stress indices were observed in groups that were subsequently administeredâ Dex and MgSO4. Serum prolidase activity increased significantly in Group HCl. Severe pathological findings were detected following HCl-induced ALI. Group Mag showed greater improvement in the pathology of HCl-induced ALI than did Group Dex. Administration of both Dex and MgSO4 did not improve the pathological scores. Conclusions: The antioxidant and anti-inflammatory effects of Dex and MgSO4 ameliorated the detrimental effects of HCI-induced ALI. However, adverse effects on hemodynamics and lung damage were observed when the two drugs were administered together.

BACKGROUND: In this study, the anaesthetic management of newborn and infant patients who underwent surgery for choanal atresia between 2009 and 2016 is discussed in the light of recently published literature. METHODS: The diagnoses, demographic data, anaesthetic risk and duration, additional anomalies, airway management, and complications that arose in 41 patients with choanal atresia who were operated on between 2009 and 2016 were evaluated retrospectively by examining their medical and anaesthesia records. RESULTS: The patients were divided into 2 groups: Group I-bilateral choanal atresia and Group II-unilateral choanal atresia. Of the 41 patients included in the study, 24 (58.53%) were in the bilateral group, and 17 (41.46%) were in the unilateral group. Fifteen (34.1%) of the patients were male, and 26 (59.1%) of the patients were female. The mean age of the 24 patients in Group I was 25.86 days (3-72), and the mean age of the 17 patients in Group II was 171.08 days (81-365). Additional congenital anomalies were present in 13 of the patients in the bilateral choanal atresia group and 3 of the patients in the unilateral choanal atresia group.Seven patients from Groups I and 2 patients from Group II were determined to have difficult airways. The laryngoscopic images from these patients were classified as grades 3 and 4 according to the Cormack-Lehane classification system. When the durations of anesthesia in the groups were compared, the duration of anesthesia in Group I was found to be significantly longer (Table 3). Anesthesia-related complications were observed in 9 patients (37.5%) from the bilateral choanal atresia group and in 4 patients (2.3%) from the unilateral atresia group. Steroids were used as prophylactics in these patients. CONCLUSIONS: Congenital anomalies and their associated risks, as well as intubation and ventilation problems and the complications that might arise, must be considered in addition to anesthetic management when repairing choanal atresia in newborn and infant patients.

AIM: We aimed to investigate efficacy of intraperitoneally administered Thymoquinone (TQ) in acetaminophen (APAP) induced renal toxicity. MATERIAL AND METHOD: Forty Wistar Albino rats were randomly divided into 4 groups of ten rats each. Control group was untreated group while rats in TQ group were treated with single dose TQ. In APAP group rats were treated with single dose acetaminophen. In TQ + APAP group TQ and APAP were administered respectively. Rats were sacrificed at 24th hour; urea, creatinine and nitric oxide levels were measured also malondialdehyde activity were assessed in renal tissue specimens. Tissue damage scores were recorded in histopathological assessment. RESULTS: Urea and creatinine levels were found significantly higher in APAP group than control group (p < 0.003). Urea and creatinine levels in APAP + TQ treated group were significantly lower than APAP treated group (p < 0.01). Serum NO activity and tissue MDA levels were higher in APAP group than control group (p ≤ 0.002). In contrast to APAP treated group serum NO activity and tissue MDA levels were found significantly lower in TQ + APAP group (p ≤ 0.03). In APAP group significant histopathological change was found compared with control group (p ≤ 0.001) where there was no significant change between control and TQ treated groups (p > 0.05). In APAP group we found significantly higher tissue damage scores than control group (p ≤ 0.001). In APAP + TQ group lower tissue damage scores were found compared with APAP group (p ≤ 0.001) while higher scores were found compared with control group (p ≤ 0.001). CONCLUSION: We can conclude that TQ treatment has therapeutical effect in APAP induced nephrotoxicity in rats.

PURPOSE: To examine the effect of intrathecally given caffeic acid phenethyl ester (CAPE) on peroxidation and total oxidant and antioxidant systems, and the effect of intrathecally given methylprednisolone (MP) in spinal cord injury (SCI) models. MATERIALS AND METHODS: Four groups of 10 rats were formed: (1) Laminectomy, intrathecal saline injection, no SCI (sham: S); (2) Laminectomy, intrathecal saline injection, SCI (control: SCI); (3) Laminectomy, intrathecally given single dose of 3 mg/kg MP, SCISCI (SCI + MP). 4) Laminectomy, intrathecally given single dose of 1 µg/kg CAPE, SCI (SCI + CAPE). Malondialdehyde (MDA), total oxidant activity (TOA), total antioxidant capacity (TAC), superoxide dismutase (SOD), and glutathione peroxidase (GPx) values in the spinal cord tissue were evaluated. RESULTS: When group S and group SCI were compared, MDA, TOA, and SOD parameters increased post-SCI (p < 0.01). When compared with group SCI, it was observed that CAPE and MP decreased the MDA, TOA, and SOD levels (p < 0.01). This decrease was more pronounced in the SCI + CAPE group. When group S and group SCI were compared, a statistically substantial decrease was observed in the post-SCI TAC levels. When compared with group SCI, it was shown that CAPE and MP treatment substantially increased TAC levels (p < 0.001). CONCLUSION: Intrathecal injection of both CAPE and MP inhibits lipid peroxidation and increase of oxidants in SCIs.

Zinc phosphide has been used widely as a rodenticide. Upon ingestion, it gets converted to phosphine gas in the body, which is subsequently absorbed into the bloodstream through the stomach and the intestines and gets captured by the liver and the lungs. Phosphine gas produces various metabolic and nonmetabolic toxic effects. Clinical symptoms are circulatory collapse, hypotension, shock symptoms, myocarditis, pericarditis, acute pulmonary edema, and congestive heart failure. In this case presentation, we aim to present the intensive care process and treatment resistance of a patient who ingested zinc phosphide for suicide purposes.
RESUMEN
BACKGROUND: The goal of our study was to determine the therapeutic effects of thymoquinone in a dose-dependent manner in a model of neuropathic pain following an experimentally applied spinal cord injury (SCI). METHODS: Fifty female adult Wistar albino rats weighing between 220 and 260 g were included in the study and were divided into 5 groups as follows: Group S (sham), Group C (control), Group T100 (100 mg/kg thymoquinone), Group T200 (200 mg/kg thymoquinone), and Group T400 (400 mg/kg thymoquinone). To begin the experiment, SCI was applied to all groups (with the exception of the sham group) following a mechanical and heat-cold test. Two weeks later, the mechanical and heat-cold tests were repeated, and a single normal saline dose was given to the sham and control groups, whereas 3 varying doses of thymoquinone were given to the other groups. The mechanical and heat-cold tests were repeated at 30, 60, 120, and 180 minutes after receiving thymoquinone. Finally, the animals were put to death via the removal of intracardiac blood. The levels of nitric oxide, total oxidant status, total antioxidant status, paraoxonase, malondialdehyde, tumor necrosis factor-α, and interleukin-1ß were determined in all of the blood samples. RESULTS: The withdrawal threshold and withdrawal latency values recorded from the mechanical and heat-cold allodynia measurements for all 3 thymoquinone groups were higher than that of the control group at all time points (ie, 30, 60, 120, and 180 minutes). There were no differences in these results between the 3 thymoquinone groups. The paraoxonase and total antioxidant status serum levels of all 3 thymoquinone groups were higher than those of the control group, whereas total oxidant status, nitric oxide, malondialdehyde, interleuken-1ß, and tumor necrosis factor-α levels were lower in the 3 thymoquinone groups than in the control group. CONCLUSIONS: Thymoquinone is beneficial for decreasing experimental neuropathic pain following SCI. However, increasing the dose does not change the effect.
RESUMEN
BACKGROUND: We aimed to investigate the correlation between the anxiety scores of parents whose children are administered anesthesia for magnetic resonance imaging (MRI) and the level of information provided to them before the MRI. The study included 146 children and their parents. The demographic information of the children and their parents was recorded. The parents were divided into two groups. In Group I, the patient's medical history and physical exam findings were recorded on a standard consultation form by an anesthesiologist. In Group II, the parents were additionally provided with more detailed information on how the anesthesia would be administered and the drugs to be used and their side effects and complications. The anxiety scores of the parents were found to be lower in Group II. A higher level of education was associated with higher anxiety scores. Intergroup comparison detected lower anxiety scores for Group II parents whose education levels were up to high school. However, no change upon receiving detailed information was detected in the anxiety scores of parents with higher education levels. In conclusion, this may lower the anxiety scores in parents informed about details of anesthesia administration and may raise parents' sense of confidence in the doctor.

The aim of the present study was to identify nosocomial infections (NIs), and their associated risk factors, in patients treated in the neurosurgery intensive care unit (NICU) of our hospital. Patients determined to have NIs between January 2008 and December 2012 were included in the study. Each patient's age, gender, microbiological culture results, underlying conditions, type of NIs, device utilization, total parenteral nutrition, reason for hospitalization, Glasgow score, and treatment were recorded and evaluated using statistical analysis. Risk factors for NIs were analyzed with a logistic regression model. During the five-year period, 60 NI episodes were detected in 56 out of 1643 patients. The mean age of the patient population was 33.3 (1-79) years. Of the patients, 22 were female and 34 were male. The overall incidence rate (NIs/100) and incidence density (NIs /1000 days of stay) of NIs were 3.65% and 6.5/1000 patient days, respectively. Regardless of the year of surveillance, the three most commonly detected NIs were bloodstream infection, shunt infection, and ventilator-associated pneumonia. No statistically significant difference was detected between infected and uninfected patients in terms of sex, age, blood transfusions, or mannitol and steroid use (p ≥ 0.05). In the present study, Glasgow scores, the frequency of prior usage of broad-spectrum antibiotics, and NICU stay durations were significantly higher among patients with infections (p < 0.001). Univariate analysis demonstrated that a low Glasgow score, re-operation, and use of mechanical ventilation were risk factors for NIs. We identified low Glasgow coma scores, long hospital stay duration, use of wide spectrum antibiotics, mechanical ventilation, total parenteral nutrition, and re-operation as risk factors for NIs.

BACKGROUND: To investigate the anesthetic management in premature infants with retinopathy of prematurity (ROP) treated with intravitreal bevacizumab (IVB) injections. METHODS: A retrospective chart review was performed for the patients with ROP who had IVB injection. Clinical characteristics, demographic variables, anesthetic medications, operation techniques, time intervals, and complications were recorded. RESULTS: Sixty-six eyes of 33 patients (23 males, 10 females) with type 1 ROP who were treated with IVB were included. A total of 66 anesthetic applications were performed. Mean gestational age at birth was 28.3 weeks (range 25-33). Mean birth weight was 1,300 g (range 600-1850). Serious ocular and systemic complications were not observed in any infant. CONCLUSION: Inhalation anesthesia with sevoflurane during IVB treatment in premature infants with ROP may be appropriate for anesthetic management.

Wilson's disease (WD) is characterized by progressive copper accumulation with hepatic and neurological impairment. Anesthesia and surgical practices may exacerbate WD and liver damage, and even cause life-threatening liver failure. Due to this existing liver damage, anesthetic management is important in WD cases in terms of drug choice, dose, and technique used. This study reports an emergency surgical procedure for trauma in a 24-year-old WD patient suffering the disease for 18 years. The operation was planned under infraclavicular brachial plexus block because of a right supracondiller/proximal humerus fracture. The selected type of anesthetic technique and agents in WD is specific. The pharmacokinetic changes in these cases are difficult to predict and require attention to drug choice and dose.

PURPOSE: The aim of this study was to investigate the attitudes of anesthesiologists to radiation exposure and current safety practice in Turkey. METHODS: The study enrolled anesthesiologists from all over Turkey, including all levels of academic degrees and all types of different institutions. Questionnaire forms were sent via e-mail to 505 anesthesiologists. The survey collected demographic data such as age, gender, position, and the institution at which the participant worked, and data about the frequency of radiation exposure during procedures and the participant's attitudes concerning radiation safety measures during these procedures. RESULTS: The questionnaire forms were delivered to 491 anesthesiologists, and 301 (61.3 %) of these were returned. Of these, 9 had not completed the questionnaire because of a lack of exposure to radiation. Among the remaining 292 personnel, the weekly frequencies of radiation exposure were more than five times (36.7 %), one to five times (50.3 %), and less than once (13 %) per week, respectively. Only a few anesthesiologists regularly wore a lead apron (30.11 %) and a thyroid shield (11.3 %) during procedures involving radiation exposure. CONCLUSIONS: This study demonstrated that nearly all anesthesiologists are regularly exposed to radiation and that few anesthesiologists in Turkey wear protective clothing, which is essential for radiation protection. Therefore, if it is not, increasing awareness about radiation protection should be an integral part of medical training and education.

PURPOSE: This study was designed to assess the correlation between the neuroprotective effect of dexmedetomidine and oxidative stress, neural inflammation and mast cell stability in rats with bupivacaine-induced sciatic nerve toxicity. METHODS: Forty adult Wistar Albino rats, eight rats per group, were used. Saline (0.3 ml of 0.9%), dexmedetomidine (20 µg/kg), 0.5% bupivacaine or 0.5% bupivacaine+dexmedetomidine (20 µg/kg) was injected into the sciatic nerve. A control group of rats received no injection. Fourteen days after injection, the sciatic nerves were harvested and total oxidant status, total anti-oxidant status, paraoxonase-1, galectin-3 and matrix metalloproteinase 2 and 9 levels were measured in the sciatic nerves. In addition, the presence and status of inflammation, edema, and mast cells were evaluated histopathologically. RESULTS: The combination of dexmedetomidine and bupivacaine alleviated oxidative stress. In addition, it decreased matrix metalloproteinase 9 and galectin-3 levels and increased matrix metalloproteinase 2 levels. Moreover, it stabilized recruited mast cells at the injury site; however, it did not significantly decrease inflammation or edema. CONCLUSION: Dexmedetomidine may ameliorate bupivacaine-induced neurotoxicity by modulating mast cell degranulation. The neuroprotective effect of dexmedetomidine may make it a suitable adjuvant agent to local anesthetics in peripheral nerve blocks.

BACKGROUND: The purpose of this study is the investigation of the effects of intrathecally injected dexmedetomidine and methylprednisolone and their dominancy over one another in rats with generated Spinal Cord Injury (SCI). METHODS: 40, female, adult Wistar Albino rats weighing 220-260 g were included in the study. The rats were fixed with Intrathecal catheter (IT) and divided into four groups. All subjects were applied T7-10 laminectomy after catheter. Group S (n:10) was injected with IT 10 µL isotonic saline; Group C (n:10) with IT 10 µL isotonic saline after SCI; Group D (n:10) with IT one doze 10 µL of dexmedetomidine after SCI; Group M (n:10) IT one dose 10 µL of methylprednisolone. The subjects were sacrificed 72 h after this operation. The damaged area was removed biochemically and histopathologically examined. RESULTS: Antioxidant and inflammatory parameters searched for in all damages tissue were statistically different in all groups from group S. They were different in group M and group D than group C (p < 0.001). After the comparison of group D and group M, PON and IL6 values were higher in group D (p = 0.003, p = 0.035) while the other two biochemical parameters were similar in both groups (Table 1). After histopathologic trials, edemas, bleeding and necrosis were found less in group S while at the most in group C (p < 0.001). In group M and group D, however, they were higher than group S and lower than group C (p < 0.001). After the comparison of group D and group M, while there was no difference in terms of edema necrosis, the amount of bleeding was lower in group D (p < 0.001) (Table 2). CONCLUSIONS: It has been discovered that intrathecal use of dexmedetomidine caused neuroprotective effects similar to methylprednisolone.

The purpose of this study is to compare the effects of spinal and epidural anesthesia on a rat transverse rectus abdominus myocutaneous flap ischemia-reperfusion injury model.Forty Sprague-Dawley rats were divided into 4 experimental groups: group I (n = 10), sham group; group II (n = 10), control group; group III (n = 10), epidural group; and group IV (n = 10), spinal group. After the elevation of the transverse rectus abdominus myocutaneous flaps, all groups except for the sham group were subjected to normothermic no-flow ischemia for 4 hours, followed by a reperfusion period of 2 hours. At the end of the reperfusion period, biochemical and histopathological evaluations were performed on tissue samples.Although there was no significant difference concerning the malonyldialdehyde, nitric oxide, and paraoxonase levels in the spinal and epidural groups, the total antioxidant state levels were significantly increased, and the total oxidative stress levels were significantly decreased in the epidural group in comparison to the spinal group. The pathological evaluation showed that findings related to inflammation, nuclear change rates and hyalinization were significantly higher in the spinal group compared with the epidural group.Epidural anesthesia can be considered as a more suitable method that enables a decrease in ischemia-reperfusion injuries in the muscle flaps.

Retrograde intubation is one of the methods used to maintain an airway in the event of a difficult intubation. Retrograde intubation has been successfully carried out on patient for whom intubation was not possible with a direct laryngoscope and fiber optic bronchoscope. The central venous catheter needle and guide wire are the materials that are the most practical to prepare and access for the retrograde intubation. To conclude, In conclusion, retrograde intubation may be good alternative to invasive airway management such as surgical tracheostomy for difficult or impossible intubations because it can be performed easily, quickly, and successfully.

OBJECTIVES: We aimed to investigate the effectiveness and complications of the percutaneous vertebroplasty (PVP) applications in vertebral compression fractures. METHODS: Our study was carried out as a retrospective study in which PVP was conducted on patients with vertebral compression fractures due to benign or malignant causes between October 2006 and December 2009. The patients' pain was evaluated on a visual analog scale (VAS). In addition, the amount of cement injected, whether or not any leakage from the vertebrae corpus was seen, and any complications resulting from the application during or after the operation were recorded. The age and gender of the patients, duration of pain, number and location of fractured vertebrae, and the duration of follow-up were also collected for evaluation. RESULTS: A total of 15 patients were included in the assessment. Of the patients, 13 were female, and the mean age was 69.5±8.5 years. A total of 19 PVPs were applied to the 15 patients. While initial VAS scores were 7.9±1.6, at the end of an average of 10.3±3.8 (range: 4-18) months of follow-up, VAS scores had fallen to 2.6±2.7. 80% of the patients reported at least a 50% reduction in pain scores compared to initial scores, and 86.7% of them reported at least a 2-point decrease in VAS scores. In three patients, leakage of cement into the intervertebral disc occurred. CONCLUSION: PVP may be used successfully in symptomatic vertebral compression fractures not responding to medical treatment, with a low rate of complications.

Many drugs used in anaesthesia have some potential fatal consequences; for example complete heart block and Q-Tc interval prolongation. Since the parasympathetic system in children is not fully developed, electrical transmission of the heart is not stable. Neostigmine is used in order to reverse neuromuscular block but it may also lead to prolongation of Q-Tc interval. We present a case of an 18-month-old male patient weighing 12kg subjected to a surgical operation because of congenital glaucoma. In order to reverse neuromuscular block at the end of operation, atropine and neostigmine were injected intravenously. However, cardiac arrest developed immediately after administration.

BACKGROUND: Osteoarthritis (OA) is the most widespread chronic joint disease worldwide. Symptomatic knee OA is observed in approximately 12% of individuals more than 60 years of age. Conservative treatments models may not be effective always, and that some of them have serious adverse effects that prompted the researchers to research different treatment methods. In this study, we investigated short- and mid-term effectiveness of intra-articular pulsed radiofrequency (PRF) applied in patients with chronic knee pain due to OA. METHODS: This study was carried out in the pain management center of a university hospital between January 2009 and June 2009. The patient record files of 31 patients who received intra-articular PRF were retrospectively reviewed. The antero-lateral area of the knee, where the intervention would be applied, was anesthetized with 1% lidocaine. An introducer needle was placed intra-articularly. PRF was started as 42°C at 2 Hz for 15 minutes. The pain of the patients was evaluated by 10 cm Visual Analog Scale (VAS). Furthermore, the ages, the gender, the symptom duration of the patients, the side of the knee on which the intervention was applied, and the complications were collected for statistical evaluation. RESULTS: Although the mean initial VAS scores of the patients were 6.1 ± 0.9 cm, it was found, respectively, to be 3.9 ± 1.9 cm and 4.1 ± 1.9 cm at the first- and sixth-month follow-ups. In general, a decrease of 32.8% in mean in the VAS scores was achieved in the last follow-up; whereas the rate of patients reporting a minimum decrease of 2 points in the VAS scores was 64.5% and the rate of patients reporting a decrease of ≥50% in their pain was calculated as 35.5%. CONCLUSION: PRF applied to the knee joint appears to be an effective and safe method.
