ABSTRACT
Background@#It has been reported that a new type of headache may develop as a result of face mask use during the COVID-19 pandemic. The aim of this study is to investigate the clinical features of face mask-related headache during the COVID-19 pandemic. @*Methods@#This is a cross-sectional study carried out on healthcare workers at the Afyonkarahisar Health Sciences University. The number of workers at our university was established. Sample size was calculated using the G*Power program. A questionnaire consisting of questions relating to pre-existing headache, an aggravation in headache, and de-novo headache was filled out by 3 neurologists with all participants. @*Results@#Data was collected from a total of 375 participants, after the exclusion of 5 individuals who refused to participate. Out of all participants, 26 (6.9%) used a filtering mask, 274 (73.1%) used a surgical mask, 75 (20.0%) participants used a combination of both masks. The number of participants with preexisting headache was 114 (30.4%) had pre-existing headache. Of those with pre-existing headache, 77 (67.5%) healthcare workers had reported an aggravation in their headache after mask use. De-novo headache was observed in 116 (30.9%) of participants. De-novo headache characteristics included throbbing in 17 (14.7%) participants and pressing in 99 (85.3%) participants. In addition, symptoms such as tachypnea, sleep disturbance, and fatigue were found to be significantly higher. @*Conclusions@#This study indicates that healthcare workers develop headaches due to use of masks during the COVID-19 outbreak.

ABSTRACT
Objective: Our purpose was to reveal the efficiency of diffusion weighted imaging [DWI] in the diagnosis of encephalitis, and to determine the relation between the apparent diffusion coefficient [ADC] values, the onset of the clinical symptoms, and the lesion extent
Methods: Conventional magnetic resonance imaging [MRI] was performed in 17 patients with encephalitis diagnosed on the basis of laboratory, clinical and radiologic findings during 2009 and 2015. Based on the duration between the onset of the symptoms and the brain MRI findings, the patients were divided into three groups. ADC values of the encephalitis lesion, the lesions' topographic analysis score, deep gray matter involvement, patients' clinical situation and the duration of the arrival to the clinic was examined
Results: Mean ADC values were 0,988 +/- 0,335x10-3 mm2/s in group I [0-2 days], 1,045 +/- 0,347x10-3 mm2/s in Group-II [3-7 days], 1,451 +/- 0,225x10-3 mm2/s in Group-III [8 days and over]. The relation between the ADC values and the duration of the arrival, topographic analysis score, the relation between the patients' clinical situation and the deep gray matter involvement were found to be statistically significant. The deep gray matter involvement was demonstrated more clearly by FLAIR images when compared with DWI
Conclusion: Conventional MRI sequences may be insufficient in showing the encephalitis lesion. DWI must be added to the imaging modalities immediately in the cases suspected of having encephalitis
