RESUMO
OBJECTIVE: The aim of this study is to investigate the effects of addition of caffeic acid phenethyl ester (CAPE) and thymoquinone (TQ) on oxidative and nitrosative stress in the liver tissue of irradiated rats. METHODS: Forty Sprague-Dawley rats were divided into five groups to test the radioprotective effectiveness of TQ and CAPE administered by intraperitoneal injection. Appropriate control groups were also studied. RESULTS: Liver antioxidant capacity, as measured by levels of total superoxide scavenger activity (TSSA), non-enzymatic superoxide scavenger activity (NSSA) and glutathione-S-transferase (GST) activity except superoxide dismutase (SOD) activity, were statistically lower in the irradiation (IR) group compared to all other groups. Total superoxide scavenger activity and NSSA were statistically higher in the IR plus TQ and IR plus CAPE groups compared to all other groups. In contrast, glutathione peroxidase (GSH-Px) activity was significantly found to increase in the IR plus CAPE group compared to control groups. The xanthine oxidase (XO), nitric oxide synthase (NOS) activities, nitric oxide (NOâ) and malondialdehyde (MDA) levels in the IR group were statistically higher than in the other groups. Moreover, XO activity in the IR plus TQ group was statistically lower than all other groups including the IR plus CAPE group. In addition, NOâ level was found to increase in all groups when compared to the normal control group. CONCLUSIONS: Thymoquinone and CAPE decrease oxidative and nitrosative stress markers and have antioxidant effects, which also increase antioxidant capacity in the liver tissue of irradiated rats.
RESUMO
BACKGROUND AND AIMS: The application of endoscopic retrograde cholangiopancreatography (ERCP) in the octogenarian population is limited. The aim of the study was to compare the clinical characteristics and outcomes of ERCP in octogenarian patients with non-octogenarian elderly patients. MATERIALS METHODS: A total of 1044 patients who underwent ERCP for the first time and are over the age of 65 were enrolled in this study. Data regarding demographic characteristics, medical history of patients, indications, technical success rate, final clinical diagnosis and complications were analyzed. 284 patients and 760 patients composed the octogenarian and non-octogenarian group, respectively. RESULTS: The mean ages in octogenarian and non-octogenarian groups were 83.99±3.85 and 71.50±4.27 years of age respectively. Both groups had similar values with regards to chronic concomitant diseases (96.6% vs. 96.5%). The most common indication of ERCP in the two groups was common bile duct stones. There was no significant difference in technical success and failure of cannulation in procedures of either group (p > 0,05). The duration of overall ERCP procedure was shorter in length in the non-octogenarian group in comparison to the octogenarian group (p = 0.004). The overall complication rate was similar in both groups (p > 0.177). The most common complication in either group was post-ERCP pancreatitis. CONCLUSIONS: ERCP is an effective and safe procedure in both octogenarian and non-octogenarian patients with naive papilla when performed by experienced endoscopists.

Fascioliasis is a zoonotic infection caused by Fasciola hepatica. It is rarely seen with icterus caused by obstruction of the common bile duct. We report five patients with obstructive jaundice due to Fasciola hepatica, who were diagnosed and managed with endoscopic retrograde cholangiopancreatography (ERCP). All cases were admitted to hospital with complaints of icterus and pain in the right upper quadrant of the abdomen; their biochemical values were interpreted as obstructive jaundice. Ultrasound and computer tomography (CT) revealed biliary dilatation in the common bile duct, but did not help to clarify the differential diagnosis. ERCP showed the presence of Fasciola hepatica in the common bile duct. After removing the flukes, the symptoms disappeared and the biochemical values returned to normal. Biliary fascioliasis should be considered in the differential diagnosis of obstructive jaundice. This report confirms the diagnostic and therapeutic role of ERCP in patients with obstructive jaundice caused by biliary fascioliasis.

Although there are many cases of oesophagitis related to pill in medical literature, there are only a few reports concerning oesophagitis related to oral contraceptives, and none about cyproterone acetate and ethinylestradiol combination (Diane-35). In this report, we describe a female patient who suffered from odynophagia and retrosternal pain after taking Diane-35 for hirsutism. The endoscopic examination revealed two well-demarcated circumferential ulcers of 1 cm diameter surrounded by relatively normal mucosa in mid-oesophagus. The patient had gone to bed immediately after taking the pill. Oral intake was stopped, and intravenous fluids and omeprazole were administered as part of treatment. The patient benefited from this approach very quickly and was discharged from hospital in 5 days. The oesophagus was completely normal in control endoscopy after 2 months. Diane-35 should be added to the list of drugs causing pill oesophagitis, and physicians should inform the patients that the pills should be taken with enough water and they should not lie down right after ingesting the pills.

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.

Pill-induced esophagitis is a complication seen in patients who use certain medications such as tetracycline and non-steroidal anti-inflammatory drugs. In this short report, we described five cases of doxycycline-induced esophagitis with endoscopic images. All of the patients were young or middle-aged women. Dysphagia or odynophagia with retrosternal pain were the main presenting symptoms in all cases. The observed injuries were at the middle third of esophagus with a normal surrounding mucosa. All patients had a history of swallowing the capsule with a small amount of water or in a recumbent position. Two patients with dysphagia were managed by intravenous fluid support and parenteral acid suppression. The symptoms were improved in 2-7 days after the ceasing of the drug and control endoscopies were completely normal in all cases after 3-4 weeks of admission. The drug-induced esophagitis is not rare with certain drugs and should be suspected in all patients presenting with chest pain and dysphagia. Physicians must warn the patients to take the pills and capsules with enough liquid and in the upright position.
