In 85% of cases, central neurological signs such as stroke, transient ischemic attack and amarozis fugax are seen, while headache and cranial nerve paralysis can be the presenting symptoms in the rest of cases. In this case report, a 35-year of age young male patient who had a progressive carotid artery dissection accompanied by complaints of left sided tinnitus and ipsilateral head and neck pain. The patient was admitted to the clinic with the diagnosis of carotid artery dissection and cerebral angiography (CA) was planned. During the CA performed the day after, three stents were placed in the dissection area. Improvement was observed in all complaints of the patient who was followed up in the clinic for 10 days. The patient was discharged in a healthy condition to return after three months for a control.

The aim of this study was to assess the effectiveness of BoNTA treatment in patients with medically resistant CH. Forty patients with CH were included in the study. Patients in the BoNTA group (n=20) were administered 10 U of BoNTA bilaterally to the frontal muscles, 20 U to the temporal muscles, 15 U to the semispinalis capitis, 15 U to the splenius capitis, and 15 U to the trapezius muscles (total: 150 U). Patients in the placebo group (n=20) received 0.2 mL of saline administrated to the same sites. All participations were evaluated 6 and 12 weeks after treatment; side effects, the number of painful days, severity (by visual analogue scale, VAS) and frequency of pain were evaluated. In the BoNTA group, the severity and frequency of pain 6 and 12 weeks post treatment were significantly lower than pre-treatment levels (p<0.05). At 12 weeks post treatment, the severity and frequency of pain in the BoNTA group were lower than in the placebo group (p<0.05). The findings suggest that BoNTA was an effective treatment for CH.

This study aimed to investigate the efficacy of topiramate therapy for migraine prophylaxis, based on vasomotor reactivity ([VMR] an indicator of cerebral autoregulation), and to identify changes in cerebral hemodynamics during the treatment. We included 20 migraine (with aura) patients (group 1) and 20 healthy controls (group 2) in the study. Transcranial Doppler monitoring was performed in both groups with patients in the supine and resting position. Using a two-sided temporal window at depths of 45-60 mm for the middle cerebral artery (MCA) and depths of 60-70 mm for the posterior cerebral artery (PCA), basal flow rates and VMR values were measured. Group 1 initially received 25 mg/d of topiramate orally, and then the dose was increased 25 mg every week. At the fourth week; the optimal dose was increased to 50 mg b.i.d. and the treatment was continued at this dose. Transcranial Doppler parameters were re-evaluated 2 months after treatment. In addition, the number of attacks per month, duration of pain, and visual analog scale (VAS) scores obtained before the treatment and 2 months after the treatment in group 1 were compared. Basal flow rates and VMR values recorded from the right and left MCA in group 1 were significantly higher than those in the control group (P < 0.05). Flow velocities obtained from the right and left MCA, and the VMR values in group 1 after topiramate treatment did not differ significantly from those in the control group (P > 0.05). In addition, the number of attacks, duration of pain, and VAS scores in group 1 were significantly lower after the treatment than before the treatment (P < 0.05). Topiramate is an effective prophylactic treatment in migraine with aura patients and appeared to play a positive role in the regulation of cerebrovascular autonomic control.

On the other hand, the literature still lacks the information whether those changes are further altered with steroid and local anesthetic injection which is a widely used treatment in this group of patients. Therefore, the aim of our study was to explore in-vivo the effects of steroid with repetitive procaine HCl injection on the median nerve of patients with CTS. This prospective clinical trial followed-up patients for 2 months. 22 patients (37 median nerves) with clinical and electrophysiological evidence of CTS were included in the study. All patients received both 40 mg of triamcinolone acetonide once and 4 ml of 1% procaine HCl twice a week for 2 weeks with the same technique. Clinical, functional, electrophysiological and ultrasonographic evaluations were performed at the study onset, and 2 months after the last injection. Electrophysiological, ultrasonographic findings (median nerve anterior-posterior diameter, transverse diameter and cross sectional area in the proximal carpal tunnel and volar bulging,) VAS scores, Boston carpal tunnel symptom and function assessment scale improved significantly (P<0.05). Steroid injection with repetitive procaine HCl injection effectively reduced the symptoms of CTS, improved the Boston carpal tunnel symptom and function assessment scale and also electrophysiological and ultrasonographic findings. Long term effects remain to be studied. Indisputably, the use of MSUS seems to be promising in this regard.

We report a 29-year-old male patient with a 2.5-year history of headaches that woke him in the middle of the night. These headaches were pulsatile and continued until sunrise. During these attacks he also suffered from allodynia over the scalp, bilateral conjunctival hyperemia, and nervousness. His brain MRI showed a 5mm by 4mm neuroepithelial cyst in the pineal gland. The peak plasma melatonin level that was measured at 2 am was 28 pg/mL. The patient underwent oral melatonin treatment (6 mg/day). After 1 month he experienced a 70% reduction in his symptoms. When the melatonin dosage was increased to 10mg/day he became headache-free, and 5 months after the treatment began, had no complaints. His 5-month follow-up plasma melatonin level at 2 am was 61 pg/mL. To our knowledge this is the first report of a patient with nocturnal headache associated with a low level of...

Patients were classified into groups according to their electroencephalogram (EEG) findings and seizure types: group 1 = GTCS with an abnormal EEG, group 2 = GTCS with a normal EEG and group 3 = PNES with a normal EEG. The control group included healthy volunteers with normal EEGs. Cortical silent period (CSP) and motor threshold (MT) were measured for all groups and the results were compared. CSPs were significantly prolonged in groups 1 and 2 when compared with group 3 and the control group. No differences were found between the MT measurements of all groups. The prolongation of CSP may demonstrate the differences between the pathophysiological mechanisms of GTCS and those of PNES.

In this study, the efficacy of local lidocaine application on anxiety and depression and its curative effect in patients with chronic TTH was investigated. Forty-eight patients (24 local lidocaine injection, 24 local saline injection group) with chronic TTH were enrolled in our study. Injections were applied to the trigger points of the muscles that are innervated by C1-C3 and the trigeminal nerve, exit points of the fifth cranial nerve, and around the superior cervical ganglion. Each patient underwent one session every 3 days. Patients were evaluated before and 3 months after the treatment. In both groups, the number of painful days in a month, visual analogue scale values, amount of analgesic use in a month, Hamilton depression score, and Hamilton anxiety score decreased after the treatment. As a result, all of the parameters were found to have improved in both groups (p < 0.05), the results were statistically significant, and the lidocaine group's response to the treatment was better than the placebo group (p < 0.001). Our findings suggest that local lidocaine administration can be an effective method in the treatment of chronic TTH.

The headaches began in childhood; the frequency of headaches has increased over the years and in the last decade headaches have occurred on a daily basis. If he wakes up before sunrise he feels much better and free of a headache; however, once he continues to sleep during and after sunrise, he suffers from tiredness, headache and nervousness. On magnetic resonance imaging (MRI), benign neuroepithelial cysts or a chronic infarct area was reported at the junction of the left medio-lateral zone of hypothalamus. After repeated MRI examinations, it was decided that the lesion on the left medio-lateral zone of hypothalamus may have disrupted the pineal gland and changed melatonin secretion. It was decided to treat him with 3 mg melatonin daily before going to bed. After a week of treatment, the patient reported that he felt very fresh and was virtually free of headaches. ᮀ Headache, Melatonine, Hypothalamic lesion

Analgesics are frequently used in the treatment of acute TTH. Antidepressants are used in prevention. In this study, the therapeutic efficacy of local application of lidocaine was investigated in Episodic Tension Type Headache (ETTH) patients. ETTH patients with pericranial tenderness (n=20, Group 1) and without pericranial tenderness (n=20, Group 2) were included in our study. Three sessions of local injection of 1% lidocaine were performed in both groups. Two-sided intramuscular injections of 1 mL were applied for each patient. The muscles treated were the frontal, temporal, masseter, sternokloidomastoid, semispinalis capitis, splenius capitis and trapezius muscles. Patients were evaluated in 1st, 2nd, and 3rd months. The number of painful days per month and pain intensities were recorded according to Visual Analog Scale (VAS) before and after the treatment. 11 male and 29 female patients were included in the study. The mean ages of Group 1 and Group 2 were 35.95 ± 9.85 (18-53) and 34.85 ± 10.04 (20-54) years, respectively. There was no difference between the groups in terms of age, gender, pain frequency and pain intensity (p>0.05). The frequency and severity of pain was significantly lower in pericranial-sensitive ETTH patients at the 1st, 2nd, and 3rd months after local lidocaine injections compared to ETTH patients having pericranial tenderness (p<0.05). Local lidocaine application can be used as an effective method in the treatment of ETTH patients with pericranial tenderness.

Analgegics are used in the acute treatment of chronic TTH and antidepressants are used in prophylactic treatment. However, further studies are needed to bring out new treatment options. The aim of our study is to investigate the effectiveness of Botulinum Neuro-toxin Type-A (BoNTA) in the treatment of chronic TTH associated with pericranial tenderness (PT). 14 patients with chronic TTH with PT were included in the study. 50 units Botox(®) injection was applied to the pericranial muscles (5 units for each muscles bilaterally: frontal, temporal, semispinalis capitis, spenius capitis and trapezius muscles) for each patient. Severity of headache was evaluated by VAS (Visual Analogue Scale) and number of days with headache per month were recorded before treatment and 2nd and 4th months after treatment. Number of days with headache per month were 19.57 ± 3.25 before treatment, 15.28 ± 4.37 at the 2nd month after treatment and 15.78 ± 3.90 at the 4th month after treatment. Severity of headache was 65.71 ± 9.16 before the treatment, 50.71 ± 13.56 at the 2nd month after treatment and 54.28 ± 10.35 at the 4th month after treatment (p<0.05). Frequency and severity of headache before treatment were significantly decreased at the 2nd month after treatment and this significance continued at the 4th month after treatment (p<0.05). BoNTA treatment may be usefull in the treatment of patients with chronic TTH associated with PT.
