Assessment of Relationship Between C-Reactive Protein to Albumin Ratio and Coronary Artery Disease Severity in Patients With Acute Coronary Syndrome.

The association of coronary artery disease (CAD) severity with increased C-reactive protein (CRP) and decreased albumin levels has been reported. However, to our knowledge, no study has investigated the usefulness of the CRP to albumin ratio (CAR) in predicting intermediate-high SYNergy between Percutaneous Coronary Intervention with TAXus and cardiac surgery (SYNTAX) score (SS) and high SS II. Consecutive patients (n = 344) treated with percutaneous coronary intervention comprised the study population. The study population was divided into 2 groups according to SS >22 and mean SS II values, respectively. Patients with intermediate-high SS and high SS II had higher CAR than patients with low SS and SS II. History of diabetes mellitus, decreased albumin, lower left ventricular ejection fraction, and elevated CAR (odds ratio [OR]: 1.020; 95% confidence interval [CI], 1.009-1.031; P < .001) were independent predictors of high SS. The presence of hypertension, decreased hemoglobin and albumin levels, and increased CAR (OR: 1.014; 95% CI, 1.004-1.023; P < .001) were independent predictors of SS II. In receiver operating characteristic curve comparison, CAR was superior to CRP and albumin in prediction of intermediate-high SS, but only CRP in prediction of high SS II. The CAR calculated from the admission blood samples could be a useful parameter for predicting CAD severity using SS and SS II.

The beneficial effects of ozone therapy in acetaminophen-induced hepatotoxicity in mice.

BACKGROUND: The aim of the present study was to determine the therapeutic effects of medical ozone therapy on acute acetaminophen (APAP)-induced hepatotoxicity which were not clearly demonstrated in prior studies. METHOD: Twenty-four mice were randomly assigned into three equal groups: Group 1 (control), Group 2 (APAP) and Group 3 (APAP +ozone). Hepatotoxicity was induced by APAP given as a single dose of 300mg/kg intraperitoneally in Groups 2 and 3. Additionally, Group 3 received 20mcg/0.5mL ozone intraperitoneal twice a day for the remaining of the study. Other groups received saline injections. On the fourth day of the study, biochemical variables (AST, ALT, ALP) and liver histopathology was assessed. RESULTS: Intraperitoneal administration of a single dose of APAP induced hepatocellular damage that was shown by both liver enzymes and histopathological changes (p<0.001). AST, ALT, ALP levels were elevated in both groups 2 and 3 and the difference from group 1 was statistically significant (p<0.01).Mean ALT and AST levels of group 2 were statistically significantly higher versus group 3 (p<0.01). In histopathological examinations; necrosis and inflammation were more prominent in Group 2 compared to Group 3 (p<0.01). CONCLUSION: Ozone showed beneficial effects on APAP hepatotoxicity at a statistically significant level. It is known that ozone has therapeutic effects in various diseases owing to its antioxidant effects. The present study suggests that ozone may be utilized as a routine supplementary therapy in acute APAP hepatotoxicity.

Evaluation of the relationship between the topographical anatomy in the axillary region of the brachial plexus and the body mass index.

To investigate the topographic anatomy of the median, musculocutaneous, radial and ulnar nerves with respect to the axillary artery and to seek whether these configurations are associated with baseline descriptive data including age, gender, and body-mass index. This cross-sectional trial was carried out on 199 patients (85 women, 114 men; average age: 46.78 ± 15.45 years) in the department of anaesthesiology and reanimation of a tertiary care center. Topographic anatomy of the median, musculocutaneous, radial and ulnar nerves was assessed with ultrasonography. Localization of these nerves with respect to the axillary artery was marked on the map demonstrating 16 zones around the axillary artery. Frequencies of localizations of every nerve in these zones were recorded, and the correlation of these locations with descriptive data including age, gender and BMI was investigated. There was no difference between women and men for the distribution of the median (p = 0.74), ulnar (p = 0.35) and radial (p = 0.64) nerves. However, the musculocutaneous nerve was more commonly located in Zone A13 in men compared to women (p = 0.02). The localization of the median (p = 0.85), ulnar (p = 0.27) and radial (p = 0.88) nerves did not differ remarkably between patients with BMI < 25 kg/m2 and patients with BMI ≥ 25 kg/m2. Notably, the musculocutaneous nerve was more often determined in Zone A10 in cases with BMI ≥ 25 kg/m2 (p = 0.001). Our results imply that the alignment of the musculocutaneous nerve may vary in men and overweight people. This fact must be considered by the anaesthetist before planning the axillary block of brachial plexus. All these informations may enlighten the planning stages of the brachial plexus blockade.

Importance of the Upper Extremity Position for a Safe and Effective Axillary Block: a Comparative Study.

OBJECTIVE: Our aim was to determine the ideal position of upper extremities during ultrasonography guidance for axillary block. The position that provides the shortest distance between the median and musculocutaneous nerves was assumed to be the most appropriate position for axillary block. METHODS: In this cross-sectional study, 120 (45 female and 75 male) patients were placed in a position with a shoulder at 90° / elbow 90° (position 1) and a shoulder 90° / elbow 0° (position 2). The intersection point of the biceps brachii muscle with the lower border of the pectoralis major muscle is defined as the proximal level (P). Distal level (D) is reffered as 5 cm below the proximal level. In the positions described above, the distance between median and musculocutaneous nerves was measured proximal (positions 1P and 2P) and distal levels (positions 1D and 2D). It was investigated whether these measurements differed between the groups and whether the body mass index or the gender. RESULTS: The shortest mean distance (10.24±3.95 mm) between the two nerves was determined when the shoulder position 90°/elbow position 0° at the distal level (1D) and the longest mean distance (13.41±4.26 mm) was determined when shoulder position 90°/elbow position 90° at the proximal level (2P). In all four cases, there was no difference in the results between men and women. There was no relationship between the measurement results and the body mass indexes and age of the patients. CONCLUSION: Appropriate positioning of the upper extremities is important for achieving optimal position during axillary block. Thereby, the procedure can be safely and effectively performed with lesser amounts of local anaesthetic solution and a decreased number of manoeuvres with needle during infiltration.

Effect of ozone and methylprednisolone treatment following crush type sciatic nerve injury.

PURPOSE:: To assess and compare the histopathological effects of ozone therapy and/or methylprednisolone (MPS) treatment on regeneration after crush type sciatic nerve injury. METHODS:: Forty Sprague-Dawley male rats were randomly allocated into four groups. Four groups received the following regimens intraperitoneally every day for 14 days after formation of crush type injury on sciatic nerve: Group I: ozone (20mcg/ml); Group II: methylprednisolone (2mg/kg); Group III: ozone (20 mcg/ml) and methylprednisolone (2mg/kg); Group IV: isotonic saline (0.9%). The histomorphological evaluation was made after biopsies were obtained from the sites of injury. RESULTS:: Significant differences were noted between groups in terms of degeneration (p=0.019), nerve sheath cell atrophy (p=0.012), intraneural inflammatory cellular infiltration (p=0.002), perineural granulation tissue formation (p=0.019), perineural vascular proliferation (p=0.004), perineural inflammatory cellular infiltration (p<0.001) and inflammation in peripheral tissue (p=0.006). Degeneration was remarkably low in Group III, while no change in nerve sheath cell was noted in Group II. CONCLUSION:: The combined use of methylprednisolone and ozone treatment can have beneficial effects for regeneration after crush type nerve injury.

Post-thoracotomy pain relief with subpleural analgesia or thoracic epidural analgesia: randomized clinical trial / Alívio da dor pós-toracotomia com analgesia subpleural ou analgesia epidural torácica: ensaio clínico randomizado

ABSTRACT CONTEXT AND OBJECTIVE: Post-thoracotomy pain is a severe and intense pain caused by trauma to ribs, muscles and peripheral nerves. The current study aimed to compare subpleural analgesia (SPA) with thoracic epidural analgesia (TEA) in patients undergoing thoracotomy. DESIGN AND SETTING: Randomized study at Ankara Numune Education and Research Hospital, in Turkey. METHODS: Thirty patients presenting American Society of Anesthesiologists physical status I-III were scheduled for elective diagnostic thoracotomy. The patients were randomized to receive either patient-controlled SPA or patient-controlled TEA for post-thoracotomy pain control over a 24-hour period. The two groups received a mixture of 3 µg/ml fentanyl along with 0.05% bupivacaine solution through a patient-controlled analgesia pump. Rescue analgesia was administered intravenously, consisting of 100 mg tramadol in both groups. A visual analogue scale was used to assess pain at rest and during coughing over the course of 24 hours postoperatively. RESULTS: In the SPA group, all the patients required rescue analgesia, and five patients (33%) required rescue analgesia in the TEA group (P < 0.05). Patients who received subpleural analgesia exhibited higher visual analogue scores at rest and on coughing than patients who received thoracic epidural analgesia. None of the patients had any side-effects postoperatively, such as hypotension or respiratory depression. CONCLUSION: Thoracic epidural analgesia is superior to subpleural analgesia for relieving post-thoracotomy pain. We suggest that studies on effective drug dosages for providing subpleural analgesia are necessary.

RESUMO CONTEXTO E OBJETIVO: Dor pós-toracotomia é severa e intensa, causada por trauma de nervos periféricos, músculos e costelas. O objetivo foi comparar analgesia subpleural (SPA) com analgesia epidural torácica (TEA) em pacientes submetidos à toracotomia. TIPO DE ESTUDO E LOCAL: Estudo randomizado no Hospital Educação e Pesquisa de Numune, em Ancara, Turquia. MÉTODOS: Trinta pacientes com o estado físico I-III da Sociedade Americana de Anestesiologistas foram agendados para toracotomia diagnóstica eletiva e escolhidos aleatoriamente para receber, num período de 24 horas, SPA ou TEA, ambas controladas pelo próprio paciente, para controle da dor pós-toracotomia. Os dois grupos receberam mistura de 3 ug/ml de fentanil com solução de 0,05% de bupivacaína por meio de bomba de analgesia controlada pelo paciente. Foi administrada analgesia de resgate por via intravenosa, com 100 mg de tramadol, nos dois grupos. No pós-operatório, a escala visual analógica foi utilizada para medir presença de dor durante a tosse ou em repouso, ao longo de 24 horas. RESULTADOS: No grupo SPA, todos os pacientes necessitaram de analgesia de resgate. Cinco pacientes (33%) necessitaram de analgesia de resgate no grupo TEA (P < 0,05). Os pacientes com SPA exibiram pontuações superiores na escala visual analógica, em repouso e ao tossir, em comparação aos que receberam TEA. Nenhum dos pacientes teve quaisquer efeitos secundários no pós-operatório, como hipotensão ou depressão respiratória. CONCLUSÃO: A analgesia peridural torácica é superior à analgesia subpleural no alívio da dor pós-toracotomia. Consideramos que estudos sobre a dosagem de drogas eficazes para proporcionar analgesia subpleural são necessários.

Locomotor stimulation by acute propofol administration in rats: Role of the nitrergic system.

BACKGROUND: The addictive potential of propofol has been scientifically discussed. Drugs' psychostimulant properties that can be assessed via measurements of locomotor activity are linked to their addictive properties. No studies that have investigated the effects of propofol on locomotor activity have been reported to date. The present study sought to investigate the effects and possible mechanisms of action of propofol on locomotor activity in rats. METHODS: Adult male albino Wistar rats (250-330g) were used as subjects. The locomotor activities of the rats were recorded for 30min immediately following intraperitoneal administration of propofol (20 and 40mg/kg), saline or vehicle (n=8 for each group). NG-nitro arginine methyl ester (l-NAME, 15-60mg/kg), a nitric oxide (NO) synthase inhibitor, and haloperidol (0.125-5mg/kg), a non-specific dopamine receptor antagonist, were also administered to other groups of rats 30min prior to the propofol (40mg/kg) injections, and locomotor activity was recorded for 30min immediately after propofol administration (n=8 for each group). RESULTS: Propofol produced significant increases in the locomotor activities of the rats in the first 5min of the observation period [F(2,21)=9.052; p<0.001]. l-NAME [F(4,35)=3.112; p=0.02] but not haloperidol [F(4,35)=2.440; p=0.067] pretreatment blocked the propofol-induced locomotor hyperactivity. l-NAME did not cause any significant change in locomotor activity in naïve rats [F(2,21)=0.569; p=0.57]. CONCLUSIONS: Our results suggest that propofol might cause a short-term induction of locomotor activity in rats and that this effect might be related to nitrergic but not dopaminergic mechanisms.

A Case Report of the First Propofol Addiction in Turkey.

Propofol is a potent anaesthetic drug and also an effective sedative agent. Also, propofol may be used for non-anaesthetic purposes such as the treatment of seizures, migraine and tension headache in clinical practice. It has been abused, particularly among healthcare providers with high mortality rate. This report presents the case of a propofol-dependent patient who was an emergency medicine doctor with no difficulties in obtaining the drug. He himself visited our clinic for the treatment of propofol dependence. We started the patient's treatment with pharmacotherapeutic medicines and individual psychotherapy. Fourteen days after starting the therapy, the patient was discharged from hospital on his own will and he did not attend the follow-up visits in the outpatient clinic. Then, we were informed of his death, which was suspected to have occurred owing to drug intoxication in the hospital in which he worked. Nevertheless, the reason of death was important; the importance of this case report is to provide information regarding the drug's dependence profile. This is the first case report indicating propofol dependence in Turkey. Because of its easy access, rapid onset time and short duration of action, propofol dependence is increasing. We think that adding propofol to the controlled drug list and improving the knowledge of the clinicians regarding its abuse potential may limit the dependence cases.

Abuse potential assessment of propofol by its subjective effects after sedation.

OBJECTIVE: In this study, we examined the euphoric effect of propofol and its high satisfaction ratio regarding its liability to be abused, particularly in painless procedures, such as colonoscopy. METHODS: Fifty subjects aged between 18 and 65 years who fulfilled the criteria for ASA 1-2 and were prepared for colonoscopy were enrolled into this study. For intravenous sedation induction, 2 mg/kg propofol was used, and additional injections were administered according to BIS values. After colonoscopy, the subjects were taken to a recovery room and observed for 30 minutes. Patients were interviewed with the modified Brice questionnare regarding the incidence and the content of dreams. A 5-point Likert scale was used to classify their dreams, and the content of the dreams was also recorded. To assess the subjective effects of propofol, the patients were asked to use the Hall and Van der Castle emotion scale; their biological states were also assessed. The patients' feelings regarding propofol were each rated as absent or present. We used the Morphine-Benzedrine Group scale to measure the euphoric effects of propofol. At the end of the study, subjects scored their satisfaction on a five-point scale. RESULTS: There were no statistically significant differences in sex age, weight, propofol dose, or satisfaction ratio (p>0.05) in the groups, although male patients received a higher dose of propofol and had higher satisfaction ratio. Patients reported no residual after-effects. The incidence of dreaming was 42%. There was no statistically significant difference in dreaming between the sexes, but male patients had a higher dreaming ratio. Dreamers received higher propofol doses and had a higher satisfaction ratio (p>0.05). All dreamers reported happy dreams regarding daily life, and their mean MBG score was 10.5. There was no correlation between MBG scores and propofol doses (r= -0.044, p= 0.761). CONCLUSIONS: We conclude that propofol functions as a reward; that patients enjoy its acute effects; and that no residual after-effects should arise. We suggest that propofol may carry potential for abuse, and further abuse liability testing is indicated.

The effect of intraarticular levobupivacaine and bupivacaine injection on the postoperative pain management in total knee artroplastic surgery.

OBJECTIVE: Total knee arthroplasty (TKA) is associated with considerable postoperative pain. We compared the effects of intraoperative intraarticular levobupivacaine and bupivacaine on postoperative analgesia and analgesic consumption after total knee arthroplasty. METHODS: Sixty ASA (American Society of Anesthesiologists) physical status II-III, 18-75 years old patients scheduled for unilateral TKA were included in this study. For the operative procedure combined spinal epidural anesthesia was given by injecting 15mg levobupivacaine in subarachnoid space at L3-4/L4- 5 in sitting position for all patients. In Group L 20ml levobupivacaine(0.5%), in Group B 20ml bupivacaine (0.5%) was injected intraarticularly 10 minutes before opening of the tourniquet at the end of the surgery. For all patients postoperative analgesia was provided with PCEA (levobupivacaine+fentanyl) and oral 1gr paracetamol four times a day. Patients' intraoperative-postoperative hemodynamical data, postoperative sensorial-motor block characteristics, side effects, PCEA demand ratios and bolus volumes, total analgesic consumption, VAS values, first mobilization time, hospitalization time were recorded. Statistical analysis was performed with SPSS version 13.00 software. RESULTS: There was no intergroup difference in demographic data, hemodynamical data, PCEA demand ratios, total analgesic consumption, first mobilization time, hospitalization time and VAS values at 0,2,72 hour. Postoperative lower VAS values were determined at 4,8,12,24 hours in Group B and at 48(th) hour in Group L(p<0.05). CONCLUSIONS: Intraarticular local anesthetic administration in addition to PCEA for post operative pain relief provides good analgesia after TKA surgery.

Do hygienic factors affect labial fusion recurrence? A search for possible related etiologic factors.

BACKGROUND/PURPOSE: The purpose of our study was to define the factors related to recurrence of labial fusion. METHODS: The data of 110 patients diagnosed with labial fusion were gathered. The data collected and queried included age and body weight of the patient, season of presentation/occurrence, frequency of diaper change, frequency of diaper dermatitis, products used for hygiene, duration of breast milk feeding, infections, presence of allergy, thickness of the adhesion, mother's use of oral contraceptive drugs before pregnancy, mother's use of alcohol/drugs/cigarettes or presence of disease during pregnancy, the number of recurrences, treatment method, presence of labial fusion among maternal sisters or any relatives, and blood estrogen levels. RESULTS: Eighty-one patients (73.6%) with labial fusion were admitted for the first time, whereas 29 patients (26.4%) had been treated previously at least once. The adhesion was denser in patients with recurrence. There was no correlation between recurrence of labial fusion and age-based body weight percentile, frequency of diaper change, frequency of diaper dermatitis, hygiene products used, presence of infection, presence of allergy, mother's use of oral contraceptive drugs before pregnancy, or presence of any pathology in other family members. CONCLUSIONS: The products used for hygiene, frequency of diaper dermatitis, duration of breast milk feeding, presence of infection, and prenatal factors showed no correlation with the recurrence of labial fusion.
