RESUMEN
BACKGROUND: Simplified risk models, such as the Apfel score, have been developed to calculate the risk of postoperative nausea-vomiting (PONV) for adult patients. In the absence of any risk factors, PONV risk is assumed to be 10%. While the presence of one of the four risk factors determined as female gender, non-smoking, PONV/car sickness history, and postoperative opioid use is associated with 20% risk for PONV, the risk increases by 20% with the addition of each risk factor, and reaches to 80% if four factors are present. AIM: : Our aim in this study is to investigate the prevalence of PONV, and whether the scoring systems used for nausea-vomiting in the literature are still valid. PATIENTS AND METHODS: Five groups of patients were included in the study with an Apfel score of 0, 1, 2, 3, 4. Each case was taken to the recovery room at the end of the operation. They were observed whether had nausea-vomiting was recorded according to the Abramowitz emesis score. RESULTS: While the PONV risk for women is 24.637 times higher than men, the PONV risk of those who had gynecological surgery is 6.27 times higher than that of the other type of surgery. Those who had urological surgery are 0.345 times less than the other type of surgery. Those who had lower abdominal surgery had a risk of PONV of 4.56 times higher than the others. As the duration of the case increases, the risk of PONV increases 1.01 times (P values P < 0.001, P < 0.001, P < 0.001, P = 0.048, P < 0.001, respectively). CONCLUSION: As a result, our PONV prevalence is considerably lower than the frequency rates mentioned in the literature. PONV scoring systems need long-term studies with larger populations to be updated.

OBJECTIVE AND BACKGROUND: Acute acetaminophen (APAP) overdose has been shown to cause toxicity and the primary treatment medication is N-acetylcysteine (NAC). Dexmedetomidine (DEX) is a sedative drug with known antioxidant properties. We researched whether DEX has an injury-reducing effect on toxicity. METHODS: Rats were divided into: Group I (control), Group II (APAP) Group III (NAC) Group IV (DEX) and Group V (NAC+DEX). Histopathologic investigations of tissues were performed and glutathione peroxidase (GSH-Px), catalase (CAT), malondialdehyde (MDA), myeloperoxidase (MPO) and beta trace protein (PGD2S) levels were studied in blood samples. RESULTS: DEX administration for hepatotoxicity and nephrotoxicity induced with APAP, caused a significant reduction in oxidative injury markers like MDA and MPO, a significant increase in GSH-Px level and a significant degree of amelioration in liver histopathologic scores. CONCLUSION: DEX administration for APAP toxicity causes a reduction in oxidative injury biomarkers, increased antioxidant biomarker levels and significant reduction in liver histopathologic scores. The beneficial effect of DEX use for detection of toxicity induced by acute APAP overdose, was shown in this study for the first time (Tab. 5, Fig. 2, Ref. 41).

INTRODUCTION AND OBJECTIVE: IMA and MPO are elevated in serum in case of end-stage renal disease. Epicardial fat tissue thickness has been considered an indicator for cardiovascular diseases recently. The present study was aimed to examine the relationship of epicardial fat tissue thickness (EFTT) with IMA and MPO levels in patients with CKD. MATERIALS AND METHODS: Predialysis CKD patients admitted to the Nephrology outpatient clinic, patients on haemodialysis and healthy volunteers were included, 111 patients were in the study. EFTT measurement was performed with the transthoracic view using an ECHO device. RESULTS: The analysis conducted among the groups in terms of IMA, MPO levels, and EFTT revealed a statistically significant difference (p < 0.001). It was determined to be the lowest in the healthy volunteers, slightly increased in the pre-dialysis group whereas it was quite high in the haemodialysis group. According to the correlation test performed, we observed that IMA, MPO levels, and EFTT were found to be highly correlated to progression of CKD. CONCLUSION: We believe that we have introduced three novel follow-up parameters, such as: IMA, MPO, EFTT to literature for the follow-up of CKD. As the levels of IMA MPO and EFTT increase, the severity of CKD increases (Tab. 4, Fig. 1, Ref. 25).

Non-alcoholic fatty liver disease (NAFLD) is the liver manifestation of metabolic syndrome and frequently accompanied with obesity, insulin resistance, hyperlipidemia and hypertension. NAFLD comprises a variety of clinical conditions ranging from simple steatosis (NAFL) to non-alcoholic steatohepatitis (NASH), with significant hepatic injury and possible progression to cirrhosis and hepatocellular carcinoma. The traditional "second hit" and the recent "multiple parallel hit" theories are the most popular explanations for the pathogenesis of NASH. NAFLD is usually diagnosed by ultrasonographic examination of the liver. For specific diagnosis of the extent and severity of NAFLD, in particular to determine NASH, the gold standard is still liver biopsy. Though, there are some promising non-invasive markers emerging for NAFLD diagnosis and assessment. Currently there is no specific therapy for NAFLD or NASH itself. Thus management of NAFLD mainly relies on initiating weight loss and on treatment of accompanying factors e.g. insulin resistance, hypertension or hyperlipidemia. In the present overview we aimed to summarize options for diagnosis and treatment of NAFLD and NASH based on the current literature.

BACKGROUND: Results are conflicting with respect to the renal effects of anti-viral agents used for hepatitis B virus infection. AIM: To compare short and long-term renal effects in real-life settings and to determine risk factors for renal impairment during treatment. METHODS: 2221 treatment-naïve patients were enrolled. Among these, 895 (302 lamivudine, 27 telbivudine, 282 entecavir, 273 tenofovir and 11 adefovir initiated patients) had 'repeated measures' of creatinine (baseline, 1st, 6th, 12th and 24th month of treatment). Telbivudine and adefovir groups were excluded from further analysis because of the low number of patients. We calculated the glomerular filtration rate (GFR) using the Modification of Diet in Renal Disease (MDRD) formula at each time point. Hypophosphataemia was also recorded. Risk factors for renal impairment were analysed. RESULTS: Tenofovir caused a decline in GFR at each time point when compared to baseline levels. However, lamivudine and entecavir did not change GFR. GFR-shifting from ≥90 to 60-89 mL/min/1.73 m(2) was comparable among groups. The proportion of patients whose baseline creatinine increased more than 25% was comparable among all anti-virals. GFR showed a decline in patients who switched from entecavir to tenofovir. One patient with compensated cirrhosis needed to change from tenofovir because of renal safety. Seven and three patients developed transient hypophosphataemia in the tenofovir and lamivudine groups, respectively. CONCLUSIONS: Although tenofovir caused a decline in GFR, differences between the anti-viral agents do not appear to be so impressive. In patients with and without renal risk factors at baseline, there is no impact of anti-virals, including tenofovir.

To explore healthcare costs associated with antiviral treatment of hepatitis B virus (HBV) in Turkey. Research-identified data from a claims processing system for all Turkish health insurance funds were analysed. Adult patients prescribed oral antiviral and pegylated interferon treatment were identified between 1 January 2010 and 31 December 2010. The first prescription date was defined as the index date. Patients were required to have HBV diagnosis within the 6-month pre-index period. Pharmacy, outpatient and inpatient claims were compiled over the study period for the selected patients, and risk-adjusted 1-year healthcare costs of patients with oral antiviral and pegylated interferon treatment were compared. Risk adjustment was carried out using propensity score matching, controlling for baseline demographic and clinical characteristics. A total of 9618 patients were identified, of which 9074 were treated with oral antiviral medication and 544 with pegylated interferon medication. The oral antiviral treatment group was older (45.28 vs 42.19, P < 0.001), less likely to be female (32.17% vs 39.71%, P < 0.001) and to reside in Southeastern Anatolia (8.29% vs 13.97%, P < 0.001) or Mediterranean region (8.90% vs 11.76%, P < 0.03) and had higher Elixhauser comorbidity index scores (60.22% vs 74.08%, P < 0.001) than the pegylated interferon group. After adjusting for confounding factors, total medical costs for pegylated interferon patients were 2771 higher than for oral antiviral patients (P < 0.001), due to higher outpatient and prescription costs. For annual healthcare costs for antiviral treatment options for HBV patients in Turkey, after adjusting for age, gender, region and comorbid condition differences, oral antiviral treatment is more costly than pegylated interferon treatment.

OBJECTIVE: To compare the effect on cognition of carotid artery stenting (CAS) and carotid endarterectomy (CEA) for symptomatic carotid artery stenosis. METHODS: Patients randomized to CAS or CEA in the International Carotid Stenting Study (ICSS; ISRCTN25337470) at 2 participating centers underwent detailed neuropsychological examinations (NPE) before and 6 months after revascularization. Ischemic brain lesions were assessed with diffusion-weighted imaging before and within 3 days after revascularization. Cognitive test results were standardized into z scores, from which a cognitive sumscore was calculated. The primary outcome was the change in cognitive sumscore between baseline and follow-up. RESULTS: Of the 1,713 patients included in ICSS, 177 were enrolled in the 2 centers during the substudy period, of whom 140 had an NPE at baseline and 120 at follow-up. One patient with an unreliable baseline NPE was excluded. CAS was associated with a larger decrease in cognition than CEA, but the between-group difference was not statistically significant: -0.17 (95% CI -0.38 to 0.03; p = 0.092). Eighty-nine patients had a pretreatment MRI and 64 within 3 days after revascularization. New ischemic lesions were found twice as often after CAS than after CEA (relative risk 2.1; 95% CI 1.0 to 4.4; p = 0.041). CONCLUSIONS: Differences between CAS and CEA in effect on cognition were not statistically significant, despite a substantially higher rate of new ischemic lesions after CAS than after CEA. CLASSIFICATION OF EVIDENCE: This study provides Class III evidence that any difference between the effects of CAS and CEA on cognition at 6 months after revascularization is small.

AIM: The aim of this study was to investigate whether conversion type of atrial fibrillation (AF) to sinus rhythm affects the P wave dispersion (PD) in patients with AF. METHODS: Based on conversion type, 95 consecutive patients with AF<3 months were divided into 3 groups: spontaneous cardioversion (SC) (N.=33, mean age: 60.6+/-11.6 years), pharmacologic cardioversion (PC) (N.=32, mean age: 59.2+/-9.6 years) and electrical cardioversion (EC) (N.= 30, mean age: 65.3+/-10.6 years). P wave duration (maximum and minimum) were measured in 12-lead ECG, and PD was calculated. RESULTS: Left atrial diameter and AF duration were significantly higher in EC (43.6+/-4.8 mm and 794.1+/-815.1 h) than SC (38.5+/-3.9 mm and 13.8+/-18.3 h) and PC (40.9+/-4.5 mm and 65.3+/-148.5 h) groups (P<0.01). P maximum was much longer in EC group compared with SC and PC group (121.6+/-9.7, 108.4+/-6.4 and 115.8+/-8.6 ms, P=0.01, respectively). There was a significant difference in PD among SC, PC and EC groups (44.4+/-9.2, 49.5+/-8.7 and 53.5+/-8.8 ms; P=0.005, respectively). PD correlated with AF duration (r=0.36, P=0.03), left atrial diameter (r=0.45, P=0.002) and conversion type (r=0.29, P=0.03). However, there was no significant association between PD and conversion type in multivariate analysis. The prolonged PD resulted from AF duration (P=0.01) and the left atrial size P=0.001). CONCLUSION: This study suggests that conversion type of AF to sinus rhythm has no effect on P wave duration and independent of AF duration and the left atrial diameter.

A young, non-obese woman aged 24 years with normal blood pressure developed intracranial hypertension after the oral use of tetracycline. Neuro-ophthalmologic examination revealed severely reduced acuity, papilledema, and concentric impaired visual fields. She was treated with acetazolamide and recurrent lumbar punctures and recovered, but without improvement in either acuity or visual fields. Intracranial hypertension is a fairly rare disease characterised by increased intracranial pressure without structural abnormalities in the brain or hydrocephalus, and is termed idiopathic in the absence of an underlying cause. Tetracycline should be considered as a cause of intracranial hypertension if a patient complains of previously unknown headache a few days after its ingestion. Headache and the presence of bilateral papilledema, decreased visual acuity and visual-field defects are indications for urgent referral to a neurologist. Therapy consists of a combination of repetitive lumbar punctures and medication. Surgical interventions include lumboperitoneal shunting and optic nerve fenestration. Intracranial hypertension may lead to irreversible decreased visual acuity and visual-field defects resulting in disability.

Selectins, are known to be increased in the serum of patients with pre-eclampsia, indicating that these molecules are possible markers of endothelial cell injury. In this study, we investigated P, E and L selectin levels in normal pregnancy, pre-eclampsia, and missed abortus. Plasma P and L selectins levels were significantly higher in normal pregnancy and pre-eclampsia than healthy controls; but plasma concentrations of E selectins were not different between these groups. Plasma P selectin was significantly higher in pre-eclampsia than normal pregnancy. Plasma concentrations of all selectins were significantly higher in missed abortus than healthy control. L selectin levels were higher in pre-eclampsia and missed abortus than normal pregnancy. We found the levels of selectins were increased in pre-eclampsia and missed abortus. Although selectins were suspected to play a role in the pathogenesis of pre-eclampsia, in conjunction with previous studies, we thought that elevated selectin levels are a non-specific consequence of endothelial injury rather than being a cause.
