Abstract
IM: Alzheimer's disease (AD) is a progressive and fatal neurodegenerative disorder resulting in degeneration of certain neuronal structures in certain brain regions and severe neuronal loss, characterized by a pathological accumulation of senile amyloid plaques (SP) and neurofibrillary tangles (NFT) within the brain . Alzheimer's disease has been associated with Type 2 diabetes mellitus (T2DM) in recent years. We designed our study on the relationship between AD and T2DM. Genome screening studies in different populations had linked the chromosome 12q24 region to type 2 diabetes. Within this region, there is the PSMD9 gene encoding a transcriptional coactivator of insulin production. METHOD The effect of PSMD9 gene E197G (rs14259) polymorphism on AD was investigated in29 Alzheimer's patients and 25 healthy controls, who were included in the study. RESULTS In our study, it was determined that the variant of PSMD9 gene E197G (rs14259) did not cause genetic risk factor for Alzheimer's disease in Turkish population. CONCLUSIONS Our study was the first to investigate the relationship between PSMD9 gene and Alzheimer's disease. A larger sample group is needed to investigate the contribution of the PSMD9 gene to Alzheimer's disease in further studies (Tab. 5, Ref. 8).

Effectiveness of dexmedetomidine in reducing bleeding during septoplasty and tympanoplasty operations. J Clin Anesth 2009; 20:437-41. [PMID: 18929284 DOI: 10.1016/j.jclinane.2008.04.008] [Citation(s) in RCA: 54] [Impact Index Per Article: 3.6] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/06/2007] [Revised: 03/18/2008] [Accepted: 04/16/2008] [Indexed: 11/19/2022]
Abstract
STUDY OBJECTIVE To determine the effect of dexmedetomidine on intraoperative bleeding during septoplasty and tympanoplasty operations. DESIGN Randomized, placebo-controlled study. SETTING Univesity medical center. PATIENTS 80 ASA physical status I and II patients, aged 18 to 65 years, 40 of whom were scheduled for septoplasty and 40 to undergo tympanoplasty operations. INTERVENTIONS Patients undergoing septoplasty (S) and tympanoplasty (T) operations were randomly divided into 4 groups. Dexmedetomidine (D) was administered to Group SD and Group TD first as a bolus dose of one microg kg(-1), then intraoperative maintenance was supplied with dexmedetomidine 0.7 microg kg(-1) hour(-1). Groups S and T (controls) were given identical amounts of saline. If systolic blood pressure measurements are greater than 20% preoperative values, then fentanyl one microg kg(-1) was given. MEASUREMENTS Intraoperative blood loss was determined with suction volumes and gauze counting. Bleeding was rated according to a 6-point scale. Hemodynamic parameters and fentanyl administration were recorded. MAIN RESULTS Group SD had less bleeding and lower bleeding scores (P < 0.05). In addition, this group received less intraoperative fentanyl (P < 0.05). The only significant difference between Groups TD and T was the amount of intraoperative fentanyl given (35.4 +/- 58.8 vs 110.0 +/- 81.0 microg) (P < 0.05). CONCLUSION Dexmedetomidine reduces bleeding, bleeding scores, and intraoperative fentanyl consumption during general anesthesia in septoplasty operations.

Abstract
This double-blind pilot study compared the local anaesthetic effects of tramadol plus adrenaline with lidocaine plus adrenaline during surgery to repair hand tendons. Twenty patients were randomly allocated to receive either 5% tramadol plus adrenaline (n = 10) or 2% lidocaine plus adrenaline (n = 10). Injection site pain and local skin reactions were recorded. At 1-min intervals after injection of the anaesthetic agent, the degree of sensory blockade was assessed by the patient reporting the extent to which they felt a pinprick, light touch and a cold sensation. Pain felt during surgical incision was also recorded. There was no difference in the quality of sensory blockade or the incidence of side effects between the two groups. Only patients treated with tramadol did not require additional post-operative analgesia. A combination of tramadol plus adrenaline provided a local anaesthetic effect similar to that of lidocaine plus adrenaline.

Effects of intramuscular and peritonsillar injection of tramadol before tonsillectomy: a double blind, randomized, placebo-controlled clinical trial. Int J Pediatr Otorhinolaryngol 2008; 72:241-8. [PMID: 18079005 DOI: 10.1016/j.ijporl.2007.11.002] [Citation(s) in RCA: 29] [Impact Index Per Article: 1.8] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 09/24/2007] [Revised: 11/01/2007] [Accepted: 11/02/2007] [Indexed: 10/22/2022]
Abstract
BACKGROUND/AIMS Our objective was to investigate the efficacy of intramuscular injection and peritonsillar infiltration of tramadol to prevent pain in children undergoing tonsillectomy. METHODS In a double-blinded trial, 45 children were randomized into three groups: infiltration anesthesia with tramadol (2 mgkg(-1)) to the peritonsillar area (INF group, n=15), intramuscular analgesia with tramadol (2 mgkg(-1)) (IM group, n=15), and the placebo controls (PL group, n=15). Visual analog scale (VAS) scores for pain assessment, heart rate (HR) and mean arterial pressure (MAP) during and after anesthesia were recorded. RESULTS Mean HR values were higher in INF than PL group at 10th, 20th, and 30th minutes of operation (P<0.05). Nine children required analgesics within the first hour after surgery in PL compared to 1 child in INF group (P=0.036). VAS scores on awakening were significantly better in INF than PL group (P=0.015). The difference between IM and PL groups was not significant for any of the parameters. CONCLUSION Peritonsillar infiltration with tramadol provided good intraoperative analgesia, less postoperative pain on awakening and lower analgesic requirement within the first hour after surgery.

Abstract
BACKGROUND AND OBJECTIVES This prospective, double-blind, randomized, placebo-controlled study was designed to determine the efficacy of dexmedetomidine compared with lidocaine in reducing the pain of propofol and rocuronium injection pain. METHODS One hundred and fifty patients, scheduled for elective surgery with general anaesthesia, were divided into five groups: saline (Group 1), dexmedetomidine 0.25 microg kg(-1) (Group 2), lidocaine 0.5 mg kg(-1) (Group 3), dexmedetomidine 0.25 microg kg(-1) plus lidocaine 0.25 mg kg(-1) (Group 4) or dexmedetomidine 0.25 microg kg(-1) plus lidocaine 0.5 mg kg(-1) (Group 5) were administered at a rate of 0.5 mL s(-1) after tourniquet application. The occlusion was released after 1 min and 5 mL of propofol was injected over 20 s. Pain was evaluated by use of a 10-point verbal analogue scale. Then, the rest of the induction dose of propofol, 3 mL of saline bolus and 0.6 mg kg(-1) of rocuronium, was injected. The response to injection of rocuronium was assessed with a four-point scale (0-3). RESULTS Groups 1 and 2 were found to have higher propofol injection pain scores than Groups 3, 4 and 5 (P < 0.05). When the study groups were compared according to the overall incidence of withdrawal movements due to rocuronium (1 response) in Groups 1, 2, 3, 4 and 5, they were different (86.7%, 60%, 36.7%, 50% and 40%, respectively) (P < 0.05). Except Group 1, there was no significant difference between the groups according to incidence of withdrawal movement after rocuronium injection (P = 0.325). CONCLUSIONS Pretreatment with dexmedetomidine is not effective in reducing injection pain of propofol, but may attenuate the hand withdrawal associated to rocuronium, as lidocaine does.

Abstract
UNLABELLED INTRODUCTION The aim of the study was to demonstrate the possible effects of preoperative intra-articular, intravenous, or intrathecal administration of morphine on postoperative pain management. MATERIALS Sixty patients undergoing arthroscopic menisectomy were included. Spinal anesthesia was performed in the lateral decubitus position with 3 ml of 0.5% hyperbaric bupivacaine, and the patients were randomized into 4 groups. The IVM (intravenous, i.v., morphine) group received 3 mg of i.v. morphine after completion of spinal anesthesia, the ITM (intrathecal morphine) group received 0.3 mg of morphine together with bupivacaine during spinal anesthesia, the IAM (intra-articular morphine) group received 3 mg intra-articular morphine diluted in 10 ml of saline after spinal anesthesia had been induced but 15 min before surgery, while the C (control) group did not receive any drugs in addition to spinal anesthesia. The sensory block level was determined 15 min after spinal anesthesia. Pain at rest (by visual analogue scale, VAS) and pain at 30 degrees of flexion (by verbal rating scale, VRS) were evaluated during each of the first 2 h of the postoperative period and once every 4 h thereafter until 24 h. In each group; the number of patients in need of analgesics, the timing of the first analgesic intake (duration of analgesia), and the cumulative dose of analgesics were recorded. RESULTS The mean duration of analgesia in the IAM group was significantly longer and the mean analgesic intake was significantly lower when compared with the other groups (p < 0.05). The mean VAS value of the ITM group at the 4th postoperative hour was significantly lower than that of the other groups. Mean VAS values at 8 and 12 h and mean VRS values at 4 and 8 h were significantly lower in the ITM and IAM groups (p < 0.05). The ITM group had the highest rates of nausea, vomiting, pruritus, and headache (p < 0.05). CONCLUSION It was concluded that the preoperative administration of morphine, either intrathecally or intra-articularly, provides postoperative pain relief. Of these two, the intra-articular route seems to be superior in terms of fewer side-effects (nausea, vomiting, and pruritus), longer duration of analgesia, and reduction of total need for analgesics.

Color Doppler evaluation of the ocular arterial flow changes in chronic obstructive pulmonary disease. Eur J Radiol 2005; 57:63-8. [PMID: 16051458 DOI: 10.1016/j.ejrad.2005.06.010] [Citation(s) in RCA: 12] [Impact Index Per Article: 0.6] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/18/2005] [Revised: 06/17/2005] [Accepted: 06/17/2005] [Indexed: 01/23/2023]
Abstract
PURPOSE To evaluate the hemodynamic changes in the extraocular orbital vessels of the patients with chronic obstructive pulmonary disease (COPD), using color Doppler ultrasonography (CDU) technique, and to compare the results with those of healthy control subjects. METHODS Forty-five patients with COPD and 17 healthy control subjects were included in this study. Patients with COPD were classified according to the Global Initiative for Chronic Obstructive Lung Disease (GOLD). Fifteen patients of stage I COPD (mild airflow limitation), stage II COPD (worsening airflow limitation) or stage III COPD (severe airflow limitation) were enrolled into Group I, II and III, respectively. End tidal carbon dioxide (EtCO(2)), peripheral oxygen saturation (SpO(2)), pulse rate (PR) and respiratory rate (RR) were measured by using capnograph/pulse oximeter in all patients. Measurements were performed in only one randomly chosen eye of each participant. The peak systolic velocity (PSV), end-diastolic velocity (EDV), and resistance index (RI) were measured in the ophthalmic artery (OA), central retinal artery (CRA), lateral short posterior ciliary artery (LPCA) and medial short posterior ciliary artery (MPCA), using CDU technique. RESULTS The PSV measurements of the OA were significantly higher in Groups II and III compared to control group (p < 0.01, p < 0.001, respectively). The RI values from OA and CRA were significantly higher in Group II and III than the control group (p < 0.05). The RI values of LPCA and MPCA were also significantly higher in Group II than the control subjects (p < 0.05). When RI values were compared, mean values of LPCA and MPCA were significantly lower in Group III than in Group II (p < 0.05). There were no significant differences between Group I and control patients about PSVs, EDVs and RI values of all arteries Statistically significant correlations were found for the EtCO(2) with PSV (r = 0.53, p < 0.01) and EDV (r = 0.51, p < 0.01) of the OA. Statistically significant correlations were also found for the SpO2 with RI (r = -0.34, p < 0.05) in the OA. CONCLUSION We concluded that COPD is associated with impaired retrobulbar hemodynamics, especially in the ophthalmic artery. Moreover, central retinal and posterior ciliary arteries with increased resistance are also found to be affected when compared with healthy control eyes.

Abstract
Lumbar puncture or identification of the epidural space is technically more difficult in children. Prior obtained information regarding the distance from skin to the dura mater may be useful as leading to an increase in success. We studied the anatomy of the posterior lumbar spine at the L4-5 intervertebral space in 137 children, using ultrasonography. Children aged between 7 and 12 years in whom weight and height are in 3-97 percentiles (recommended for healthy Turkish boys and girls) were investigated. The measured distance from skin to dura mater was found significantly higher in girls (2.59+/-0.44 cm) than boys (2.43+/-0.46 cm) (p<0.05). Prediction of the posterior dural depth at L4-5 level was obtained using single linear regression equation. All demographic variables correlated significantly with the dural depth in both sexes. In girls the skin-duramater distance achieved highest correlation ranks with weight and body surface area (BSA): 'dural depth' (cm)=1.094+[0.048 x weight (kg)], r=0.79, p<0.01 and 'dural depth' (cm)=0.337+[2.119xBSA m2], r=0.76, p<0.01). We concluded that the distance between the skin and the dura mater at the level of L4-5 interspace could be predicted using a statistical model based on the age, weight, height or BSA of children aged between 7-12 years old.

Abstract
BACKGROUND AND OBJECTIVE This prospective, double-blind, randomized, placebo-controlled study compares the effects of ephedrine and ketamine on injection pain, and hypotension from propofol. METHODS After obtaining the approval of the Ethics Committee, 75 patients (ASA I-II) scheduled for elective operations with general anaesthesia were divided into three groups. Saline 2 mL (Group S, n = 25), ketamine 0.5 mg kg(-1) (Group K, n = 25) or ephedrine 70 microg kg(-1) (Group E, n = 25) were administered over 5 s after tourniquet application. After releasing the tourniquet, propofol 2 mg kg(-1) was injected in 30 s. Pain was evaluated on a numerical scale (0-10) where 0 represented no pain and 10 the most severe pain possible. Systolic, diastolic blood pressures and heart rates were recorded preoperatively, 1 min after propofol injection, before intubation and 1, 2 and 3 min after intubation in all patients. RESULTS The incidences of pain in Groups S, E and K were similar (84%, 80% and 72%, respectively). The mean pain score in Group K (2.1, SD 3.1) was significantly lower than those of Groups S and E (4.9, SD 2.6 and 4.6, SD, 3.3, respectively) (P < 0.05). The systolic and diastolic blood pressure values in Group K (120 +/- 27 mmHg) and Group E (123 +/- 21 mmHg) before intubation were significantly higher than that of Group S (104 +/- 25 mmHg) (P < 0.05). There was no significant difference between the mean heart rate values of the groups. CONCLUSIONS Low dose ketamine or ephedrine pretreatment may prevent hypotension due to propofol induction. Despite the reduction in injection pain intensity after ketamine, the study drugs were found to be ineffective in lowering the injection pain incidence.

Abstract
BACKGROUND AND OBJECTIVE The purpose of intraperitoneal local anaesthetic administration is to block visceral nociceptive conduction and to provide an additional route of analgesia. The present study evaluates the effects of sequential injections of bupivacaine on postoperative pain through a subphrenic catheter. METHODS In this double-blinded controlled study, patients scheduled for gynaecological laparoscopy were randomly divided into two groups. One group received 20 mL of saline with 1:200000 epinephrine through a subphrenic catheter before the incision closure and at 4-hourly intervals for the first postoperative 20 h. The second group received 20 mL of bupivacaine 0.125% with 1:200000 epinephrine at the same injection times. Postoperative pain scores and consumption of analgesics were compared. RESULTS There were no statistical differences in pain scores at rest or incidence of shoulder pain between the two groups, but the patients of the bupivacaine group reported lower pain scores on coughing only in the first hour postoperatively (P = 0.007). Although the patients consumed comparable amounts of metamizole and ondansetron, the number of patients requiring supplemental meperidine and flurbiprofen in the bupivacaine group were significantly lower than in the saline group (P < 0.05). CONCLUSIONS This study demonstrates that intraperitoneal bupivacaine may reduce pain on coughing in the early postoperative period and the consumption of analgesics postoperatively. The subphrenic catheter technique had no impact upon pain at rest and shoulder-tip pain after gynaecological laparoscopy.

Abstract
OBJECTIVE A prospective study was carried out to find the exact site of obstruction in sleep model and to quantitatively evaluate the effect of Jaw-thrust maneuver (JTM) in opening the obstructed airway using flexible fiberoptic endoscope. METHODS Twenty-eight ASA physical status I or II patients with snoring symptom undergoing elective surgery were included. The patients were held in supine position without hyperextension of the neck. Having induced anesthesia, the base of the tongue and laryngeal inlet and/or epiglottis were visualized using endoscope. The patients' epiglottides were classified as leaf-shaped, curved (concaved or omega-shaped) and floppy types. We graded the airway opening at the level of epiglottis into six grades and obstruction at the tongue base level into four grades. The grades during inspiration (GrIns), expiration (GrExp) and after JTM (GrJTM) were recorded and compared with Pearson chi-square test. RESULTS The strictly curved (Omega-shaped or concaved) epiglottis supplied a salvage pathway for airflow that resisted collapsing with the posterior movement of the tongue base in 2 patients. When we compared GrIns with GrExp for epiglottis the difference was statistically significant (chi(2) = 0.001), but the difference for tongue base was not (chi(2) = 0.152). After JTM, GrJTM for both epiglottis and tongue base were significantly better than GrIns and GrExp (chi(2) < 0.001). CONCLUSION Tongue base was the principal site of obstruction although during the respiratory cycle the position of epiglottis changed prominently and increased the obstruction in inspiration. JTM alone significantly relieved the obstruction at the tongue base and epiglottis levels and increased the retroglossal airway.

Morphine modulates inducible nitric oxide synthase expression and reduces pulmonary oedema induced by α-naphthylthiourea. Eur J Pharmacol 2005; 511:183-9.

Abstract
This study was designed to investigate the possible participation of morphine in pulmonary oedema induced by alpha-naphthylthiourea (ANTU), which is a well-known noxious chemical agent in the lung. Injection of ANTU (15 mg/kg i.p.) produced pulmonary oedema as indicated by an increase in lung weight/body weight ratio and pleural effusion reaching a maximum within 4 h in rat. Administration of morphine prior to ANTU significantly inhibited to pulmonary oedema with a dose-dependent manner. The protective effect of morphine is prevented by peripheral opioid receptor antagonist, naloxone methiodide. ANTU-treated rats were shown positive by inducible nitric oxide synthase immunohistochemical staining. There was no staining in the control group. On the other hand, the degree of staining was markedly reduced in tissue sections by morphine. These results suggest that previous administration of subcutaneous morphine has preventive effect on ANTU-induced pulmonary inflammatory reaction and its effect mediated via peripheral opioid receptors. Application of naloxone with ANTU has no effect on the lung parameters indicating that endogenous opioids do not modulate ANTU-induced damage.

Abstract
This study examines the intracranial pressure and temperature dispersion in a rabbit model after epidural balloon compression. Right and left supratentorial, intraventricular and infratentorial pressures and temperatures of the rabbits have been measured before epidural balloon was placed. Afterwards, the epidural balloon was placed in right parietal epidural area. The intracranial pressure and temperature dispersion values were recorded after inflation with 0.3 and 0.6 ml, respectively. The control values of intracranial pressure measurements of four different brain regions were found to be similar. When the balloon was inflated to 0.3 ml, the intracranial pressure distribution was found to be equal in all the fields. After the balloon was inflated up to 0.6 ml, right and left supratentorial intracranial pressure values were found to be equal. However, infratentorial pressure values were lower and intraventricular pressure values were higher when compared with the right hemisphere. Before the inflation and at two different inflation volumes, perfusion pressure and temperature dispersion were found to be similar between right hemisphere and other compartments. We conclude that, the effective mechanism in cerebral temperature regulation may be related to preserved cerebral perfusion pressure and cerebral blood flow.

Abstract
Recently, it has been shown that tramadol was an effective local anesthetic in minor surgery. In this study, its efficacy for relieving postoperative pain was evaluated. Forty patients undergoing minor surgery (lipoma excision and scar revision) under local anesthesia were included. The patients were randomly allocated into two groups: In group T (n = 20), 2 mg/kg tramadol, and in group L (n = 20), 1 mg/kg lidocaine were given subcutaneously. In both groups, the injection volume was 5 mL containing 1/200,000 adrenalin. The degree of the erythema, burning sensation, and pain at the injection site were recorded. Incision response, which is a degree of the pain sensation during incision, was recorded and graded with the visual analog scale (VAS) 0-10. After incision, VAS values were recorded at 15-min intervals. When the VAS score of the pain during surgery exceeded 4, an additional 0.5 mg/kg of the study drug was injected and this dosage was added to the total amount. Patients were discharged on the same day. Subjects with VAS > or =4 were advised to take paracetamol as needed. No side effects were recorded in either group except for 1 patient complaining of nausea in group T at the 30th min of operation. After 24 h, patients were called and the time of first analgesic use and total analgesic dose taken during the postoperative period were recorded. During the 24 postoperative hours, 18 of 20 (90%) subjects did not need any type of analgesia in group T, whereas this number was 10 (50%) in group L (P < 0.05). The time span before taking first analgesic medication was longer (4.9 +/- 0.3 h) in group T than that of group L (4.4 +/- 0.7 h) (P < 0.05). We propose that tramadol can be used as an alternative drug to lidocaine for minor surgeries because of its ability to decrease the demand for postoperative analgesia.

Abstract
Hydatid disease of the urogenital system, especially of the retroperitoneum and seminal vesicles, is a very rare condition. We report a case of hydatid disease located in the liver, retrovesical region and seminal vesicle that was diagnosed incidentally while investigating the etiology of syncope. Transabdominal and transrectal ultrasonography revealed hypoecoic multicystic masses which had thin septations and walls in the liver, retrovesical region and seminal vesicle. Abdominal computed tomography examination showed multicystic low attenuation masses in the same region. Pelvic magnetic resonance image findings revealed multiple cystic masses in the retrovesical region and the right seminal vesicle. In conclusion, the diagnosis of hydatid disease should be kept in mind with patients who have cystic lesions in seminal vesicle and retrovesical region.

Abstract
The aim of this study was to study the usefulness of erythrocyte antigen (EA) measurement to study engraftment after allogeneic HSCT. In all, 31 consecutive patients receiving HLA-identical bone marrow (BM) (n=13) or peripheral blood stem cells (n=18) were investigated. Apart from the ABO group, 15 EAs representing six minor blood groups were followed by the simple tube agglutination technique. A total of 20 (64.5%) patients received ABO-identical, eight (25.8%) received ABO minor and three (9.7%) received ABO major mismatched grafts. In all, 29 patients were followed for a median of 12 (6-16) months; 65% of the patients expressed donor type EA 1 month and almost all did so 6 months after transplant. Reticulocyte engraftment was significantly shorter than EA engraftment (median 18 vs 35 days) (P=0.001). Patients who received PB stem cells showed significantly faster EA and reticulocyte engraftment than patients who received BM stem cells (P=0.038 and 0.025). ABO compatibility did not have an impact on reticulocyte and EA engraftment (P=0.4 and 0.55). The earliest donor type EA detected was from the Rh and Kidd system. These data suggest that EA and reticulocyte assays are useful in monitoring engraftment.

Abstract
General and regional anesthesia (spinal and epidural) can be performed successfully for lumbar disc surgery. The aim of this study was to assess the superiority of general anesthesia or epidural anesthesia techniques in lumbar laminectomy and discectomy. Sixty patients undergoing lumbar partial hemilaminectomy and discectomy were randomly divided into two groups receiving standardized general anesthesia (GA) or epidural anesthesia (EA). Demographically, both groups were similar. Surgical onset time (36.72 +/- 5.47 vs. 25.40 +/- 7.83 minutes) was longer in the EA group, but total anesthesia time (154.32 +/- 35.73 vs. 162.40 +/- 26.79 minutes) did not differ between the two groups. Surgical time (118.80 +/- 35.42 vs. 139.60 +/- 26.80 minutes) was longer in the GA group. The heart rate and mean arterial pressure values of the EA group measured 15, 20, and 25 minutes after local anesthetic administration to the epidural catheter were found to be lower than in the GA group measured after induction of general anesthesia. The frequency of bradycardia (EA vs. GA, 3 vs. 2), tachycardia (3 vs. 7), and hypotension (6 vs. 4) during anesthesia did not differ between the groups, but the occurrence of hypertension (1 vs. 7) was higher in the GA group. Blood loss was less in the EA group than in the GA group (180.40 +/- 70.38 vs. 288.60 +/- 112.51 mL). Postanesthesia care unit (PACU) heart rate and mean arterial pressure were higher in the GA group. Peak pain scores in PACU and postoperative 24 hours were higher in the GA group when compared with the EA group. Nausea was more common in the GA group both in PACU and 24 hours after surgery. There was no difference between the hospitalization duration of the groups. In conclusion, this study suggests that EA is an important alternative to GA during lumbar disc surgery.

Abstract
BACKGROUND Recent studies have shown that a local anaesthetic action of tramadol 5% was able to induce a sensory block to pinprick, touch, and cold similar to that of lidocaine 1%. The aim of this study was to compare the local anaesthetic effects of tramadol hydrochloride with prilocaine. METHODS Sixty ASA I or II patients, undergoing excision of the cutaneous lesions under local anaesthesia, were included in the study. Patients were randomly assigned to receive either 1 ml of tramadol 5% (Group T, n=30) or 1 ml of prilocaine 2% (Group P, n=30) intradermally, in a double-blinded fashion. The degree of the burning sensation and pain at the injection site was documented. Sensory block was assessed 1 min after injection. The patient was asked to report the degree of sensation and to grade touch and pinprick sensation. Two minutes after drug administration, incision was performed and intensity of pain, felt by the patient was evaluated on a four-point scale (0-3). Any local adverse effects were recorded. RESULTS There was no difference in the quality of block between the two groups. Side effects were noted in both groups with a significant increase in the incidence of local reaction (rash) in Group T (seven patients) when compared with Group P (one patient) (P<0.05). Seven patients in Group T vs four patients in Group P complained of burning at the injection site (P>0.05). CONCLUSIONS Intradermal tramadol 5% can provide a local anaesthesia similar to the prilocaine but the incidence of local adverse effects is higher.

Abstract
Parachuting is a unique method of deploying troops. Accidents in parachuting are common, but usually carry minimal risk for severe injury. Most accidents occur during landing and injuries often affect the lower limbs and spine. Traumatic amputation of a limb is an extremely rare event in parachuting. We present a case of a parachutist who suffered a traumatic amputation of the left hand during jumping off the plane.

Abstract
In the 10-year period 1975-1984, 1188 children were admitted to the Children's Hospital of Hacettepe University in Ankara with a diagnosis of poisoning. Retrospective analysis of their medical records showed that the incidence of poisoning with medicinal drugs was 64.0%, while pesticides accounted for 17.8% and plants for 6.7% of total cases. The majority (69.9%) of cases were due to accidental poisoning, 70.6% of which occurred in children under 5 years of age; 15.1% of the poisonings were diagnosed as therapeutic mishaps of which 68.3% involved children under 5 years of age. Analgesics (186 cases), barbiturates (176 cases) and tranquilizers (37 cases) were the most common drugs encountered, however, the two drugs most frequently overused were aspirin (146 cases) and Optalidon (175 cases). Overall mortality was 4.9% (58 cases). Fifty per cent of fatalities were due to accidental poisoning while 41.4% (24 cases) were due to therapeutic mishaps. This study is presented as a background to the need for the development of a Poison Information Service for Ankara.
