Our results suggest that GON blockade with bupivacaine was superior to placebo and was found to be effective, safe, and cost-effective for the treatment of CM. According to our knowledge, this is the first randomized, multicentre, double-blind, and placebo-controlled study in the literature in this field of work.

Methylphenidate is commonly believed to lower seizure threshold. The safe use of methylphenidate has not been clarified in patients with attention-deficit hyperactivity disorder (ADHD) and concomitant active seizure or electroencephalographic (EEG) abnormalities. Patients with ADHD and active seizures (n = 57) and patients with ADHD and EEG abnormalities (n = 62), 6 to 16 years of age, were included in the study. The safety and efficacy of treatment with antiepilepsy drugs combined with methylphenidate were determined by assessing seizure frequency, changes in ADHD symptoms, the Conners' Rating Scales, EEG differences, and side effects. The Conners' Rating Scales, performed by parents and teachers, and mean total ADHD symptom scores at the beginning of the study and at the end were significantly different (P = .05 for the Conners' Rating Scales and P = .001 for ADHD symptom scores). Methylphenidate had a beneficial effect on EEG. Seizure frequency did not change from baseline. The side effects of methylphenidate were mild and transient Methylphenidate is safe and effective in children with ADHD and concomitant active seizures or EEG abnormalities.

This study reports the first validation of a translated version of the S-LANNS into another language. The results suggest that the Turkish version of S-LANSS is a reliable and valid differential diagnostic measure of neuropathic pain in chronic pain patients.

We determined the seroprevalence of hepatitis B virus (HBV) and hepatitis C virus (HCV) among health care workers (HCWs) at Gülhane Military Medical Academy, Haydarpasa Training Hospital in Istanbul, Turkey. Between April 1998 and September 2000, 702 HCWs were included in the study. The blood samples were tested for hepatitis B surface antigen (HBsAg), hepatitis B surface antibody (anti-HBs) and HCV antibody (anti-HCV) using third-generation tests, with confirmation by reverse transcriptase-polymerase chain reaction. Seroprevalence rates were compared with those detected in 5670 blood donors during the same period. HBsAg, anti-HBs and anti-HCV were detected in 21 (3.0%), in 480 (68.4%) and in 2 (0.3%) of 702 HCWs respectively. HBsAg and anti-HCV rates were 2.1 and 0.4% in blood donors, respectively. These data show that the prevalence rates of HBV and HCV were similar with prevalence rates detected in randomized blood donors showing that universal infection-control precautions and encouraging HBV vaccination reduces HCW infection with hepatotropic viruses.

The retrobulbar circulation and flow hemodynamics in the left VA may be altered in both headache and headache-free periods in migraineurs without aura. The differences found between migraineurs and control subjects may implicate autonomic dysfunction in migraineurs.

The effect of azithromycin on bronchial hyperresponsiveness was measured in a group of 11 patients with mild asthma. Azithromycin 250 mg orally was administered intermittently to all the patients twice a week for eight weeks. The only other treatment was inhaled beta2 agonist, when required. A histamine inhalation test was performed at the beginning and at the fourth and the eighth week of the study. The mean PC20 values increased significantly over the initial value at the eighth week after the administration of azithromycin (p < 0.05) but mean values for FEV1 and FEV1 percent predicted did not differ significantly. These results suggested that eight weeks of intermittent, low-dose administration of azithromycin in patients with mild asthma might reduce the severity of bronchial hyperresponsiveness.

Iron and ferritin are known to have an important role in stroke as well as in other disorders. This prospective study was designed to determine whether administering ferritin levels might help to estimate the severity and prognosis of stroke. Fifty-one patients with a diagnosis of acute stroke were included in the study within 24 h from onset of symptoms. Serum ferritin and cortisol levels were assayed at admission. Clinical status was determined by the Canadian Stroke Scale at admission and on day 21. Serum ferritin level was found to be higher in patients with large lesion size (P < 0.01), deteriorated neurologic status during clinical follow-up (P = 0.03) and deceased patients (P < 0.01). Serum ferritin level was correlated with neurologic deficit (r = 0.50, P < 0.001). No correlation was found between serum cortisol and ferritin levels (r = 0.07, P = 0.7). Serum ferritin level (P = 0.007; OR = 1.02; 95% CI, 1.01-1.03) and large size of lesion (P = 0.021, OR = 11.92; 95% CI; 1.46-197.12) were independently associated with mortality. Increased serum ferritin levels correlate to severity of stroke and the size of the lesion.
