Cerebral blood flow velocity in migraine and chronic tension-type headache patients
S Karacay Ozkalayci, B Nazliel, HZ Batur Caglayan, C Irkec Department of Neurology, Faculty of Medicine, Gazi University, Ankara, Turkey Introduction: The present study seeks to use transcranial Doppler ultrasound to evaluate cerebral blood flow velocities in anterior and posterior circulation arteries, during an attack-free episode in migraine patients, with and without aura, as well as in chronic tension-type headache patients who were not receiving prophylactic medication. Methods: A total of 50 patients (35 female, 15 male) were evaluated during a headache-free episode: 30 migraine patients without aura (mean age: 32±8 years), 10 migraine patients with aura (mean age: 34±4 years), and 10 patients with chronic tension-type headache (mean age: 34±5 years). Results: No significant difference was present between anterior, middle, and posterior cerebral and vertebral arteries’ blood flow velocities between migraine patients, with and without aura, or in patients with a tension-type headache, and normal controls (p>0.05). However, a significant increase in basilar artery cerebral blood flow velocities relative to controls was present in patients with a tension-type headache (p>0.001). Conclusion: It is difficult to predict the main reason for the significant increase in basilar artery blood flow velocities in patients with chronic tension-type headache. It may be due to constriction of conductance or the dilatation of the resistance vessels.

Cerebral blood flow velocity in migraine and chronic tension-type headache patients
Introduction: The present study seeks to use transcranial Doppler
ultrasound to evaluate cerebral blood flow velocities in anterior and
posterior circulation arteries, during an attack-free episode in
migraine patients, with and without aura, as well as in chronic
tension-type headache patients who were not receiving prophylactic
medication. Methods: A total of 50 patients (35 female, 15 male) were
evaluated during a headache-free episode: 30 migraine patients without
aura (mean age: 32 +/- 8 years), 10 migraine patients with aura (mean
age: 34 +/- 4 years), and 10 patients with chronic tension-type headache
(mean age: 34 +/- 5 years). Results: No significant difference was
present between anterior, middle, and posterior cerebral and vertebral
arteries' blood flow velocities between migraine patients, with and
without aura, or in patients with a tension-type headache, and normal
controls (p>0.05). However, a significant increase in basilar artery
cerebral blood flow velocities relative to controls was present in
patients with a tension-type headache (p>0.001). Conclusion: It is
difficult to predict the main reason for the significant increase in
basilar artery blood flow velocities in patients with chronic
tension-type headache. It may be due to constriction of conductance or
the dilatation of the resistance vessels

Unexpected Coexistence of a Derivative t(21;21) and Complementary Mosaic r(21) in a Female with Multiple Miscarriages
The case presented here describes a female patient with recurrent miscarriages and a normal microarray analysis result. However, the coexistence of a robertsonian (21;21) translocation and complementary mosaic ring chromosome 21 was detected by karyotyping and FISH analysis. Partial trisomy 21 was found with QF-PCR and microarray analysis in one of the fetuses. The aim of this report was to emphasize the diagnostic importance of conventional cytogenetics. (C) 2019 S.
