Validity and reliability of Turkish translation of Migraine Disability Assessment (MIDAS) questionnaire in patients with migraine.

The Migraine Disability Assessment (MIDAS) questionnaire is a brief, self-administered questionnaire which is designed to quantify headache-related disability in a 3-month period. We have tested a Turkish version of the MIDAS questionnaire in 60 migraine patients. Sixty of the clinically diagnosed migraine headache sufferers were enrolled in a 90-day diary study and completed the MIDAS questionnaire in the first, 21st and the last day of the 90-day study. The scores taken from the diary and the scores of the MIDAS taken at different times were evaluated by the correlation tests of both Pearson and Spearman for each question and total scores. Cronbach's scores taken from the diary and taken from the test of the MIDAS which was applied at different times were evaluated. Pearson's correlation on the responses in the initial MIDAS questions was between 0.44 (reduced productivity in household chores) and 0.78 (missed work or school days). The correlation of the Spearman was similar to the Pearson values. As a result, we found that the overall score of the MIDAS has a good reliability and its internal consistency is also good (Cronbach's alpha 0.87). These findings support the use of the MIDAS questionnaire as a clinical and research tool on Turkish patients.

Relationship between nosocomial infection and mortality in a neurology intensive care unit in Turkey.

Few previous studies have evaluated the relationship between nosocomial infection and mortality in a neurology intensive care unit (ICU). In this study, patients treated for more than 24h in the neurology ICU of the Ankara Training and Research Hospital, Turkey were followed until death or two days after discharge by prospective daily surveillance. The study period was 14 months. One hundred and sixty-nine ICU-acquired infections occurred in 74 (38.9%) of 190 patients during 2006 patient-days. The overall rate of ICU-acquired nosocomial infection was 88.9/100 patients and 84.2/1000 patient-days. While the overall mortality rate was 60%, mortality in patients with nosocomial infections was 69%. In univariate analysis, infection (nosocomial and community-acquired) (P=0.002), nosocomial infection (P<0.05), mechanical ventilation (P<0.0001), presence of two or more underlying diseases (P=0.01), parenteral nutrition (P<0.0001), steroid treatment (P=0.003) and a low Glasgow Coma Scale (GCS) score (P=0.0001) were identified as risk factors for mortality. Stepwise logistic regression analysis showed nosocomial infection (P<0.05), mechanical ventilation (P=0.009), the presence of two or more underlying diseases (P<0.05) and a low GCS score (P=0.0001) to be risk factors for ICU mortality. It was concluded that nosocomial infection increases the risk of mortality by a factor of 1.69. The impact of nosocomial infection on mortality in our ICU was higher in patients with high GCS scores and patients aged between 66 and 75 years. In particular, nosocomial infection increased mortality among patients with less severe illnesses.

Magnetic resonance imaging of patients with cervicogenic headache.

Cervicogenic headache (CH) is a syndrome which is postulated to originate from nociceptive structures in the neck or head. The anatomical neck or head structures that are responsible for the pain in CH have not been clearly identified, but the pain in these patients probably originates from the structures of the cervical spine. In this study, cervical MRI were studied in 22 patients with cervicogenic headache and 20 control patients who did not have any disease which may effect the bone and muscle structures of cervical region. MRI imaging of cervical vertebra showed a disc bulging in 10 (45.4%) out of 22 patients with CH and in 9 (45.0%) of 20 controls (P > 0.05). The distribution of pathological lesions in patients and controls were not significantly different (P > 0.05). As a result, MRI may not be an adequate method to detect pathological findings underlying the aetiology of CH such as nerve roots, intervertebral joints and periosteum.

The 'dry-needle technique': intramuscular stimulation in tension-type headache.

The 'dry-needle technique', an intramuscular stimulation technique carried out by using a fine solid, 1-inch long, 30-gauge needle, was investigated in the treatment of tension-type headache (TTH) in a randomized, placebo-controlled trial. Fifteen patients with TTH received intramuscular needle insertions into six designated trigger points, while 15 controls received subcutaneous insertions. Headache indices, muscle tenderness and neck ROMs were evaluated before and after treatment. Mean headache indices improved significantly after treatment, both in the treatment group and in the placebo group, but the difference between the two groups was insignificant. In the treatment group the tenderness score and the neck ROM limitation score were significantly improved after treatment, while there was no significant improvement in the placebo group. We conclude that more and larger controlled, comparative trials are needed to show whether the dry-needle technique is an effective non-pharmacological alternative for the treatment of TTH.
