[Clinical Aspects of Cervicogenic Headache].

Cervicogenic headache (CEH) is a lateralized non-pulsative headache syndrome caused by cervical spine disorders. The headache is initiated in the neck, which subsequently spreads to the occipital, frontal, and orbital regions, and is accompanied by ipsilateral shoulder pain. The prevalence of CEH is considered to be 15-20% among cases of chronic headache.

The Clinical Features, Risk Factors, and Surgical Treatment of Cervicogenic Headache in Patients With Cervical Spine Disorders Requiring Surgery.

Objective: To clarify the clinical features and risk factors of cervicogenic headache (CEH; as diagnosed according to the International Classification of Headache Disorders-Third Edition beta) in patients with cervical spine disorders requiring surgery.

Background: CEH is caused by cervical spine disorders. The pathogenic mechanism of CEH is hypothesized to involve a convergence of the upper cervical afferents from the C1, C2, and C3 spinal nerves and the trigeminal afferents in the trigeminocervical nucleus of the upper cervical cord.

[Perioperative management of Parkinson's disease].

Several studies have demonstrated the serious impact of surgeries on patients with Parkinson's disease (PD). In addition, PD is a risk factor for postoperative complications and prolonged hospital stays. Discontinuation of anti-Parkinsonian drugs due to surgery causes an exacerbation of Parkinsonism and sometimes Parkinsonism-hyperpyrexia syndrome (PHS).

[Effectiveness of low dose PCEA for postoperative pain after laparoscopic gynecological surgeries--a comparison of laparoscopic ovarian cystectomy and myomectomy].

Background: We evaluated the effectiveness of low-dose patient-controlled epidural analgesia (PCEA) in the patients undergoing laparoscopic gynecological surgery, and investigated the difference of postoperative pain between patients for laparoscopic ovarian cystectomy and those for myomectomy.

Methods: Thirteen patients (ASA PS 1 or 2), scheduled for laparoscopic surgery, were enrolled in this study. They were divided into two groups of ovarian cystectomy (group C, n=17) and myomectomy (group M, n=13).

Nasal sumatriptan as adjunctive therapy for idiopathic trigeminal neuralgia: report of three cases.

We examine the effect of nasal sumatriptan as an adjunctive therapy in 3 patients with idiopathic trigeminal neuralgia refractory to carbamazepine (CBZ) and found that this therapy might be suitable for patients for whom the CBZ dose cannot be increased, who are under poor pain control, and who are not candidates for nerve blocks or surgery.

Addition of 0.1% bupivacaine to buprenorphine and droperidol in patient-controlled epidural analgesia improved postoperative pain scores on coughing after gynecological surgery.

Study Objective: To compare the analgesic efficacy of additional 0.1% bupivacaine to patient-controlled epidural analgesia (PCEA) using buprenorphine and droperidol after gynecological surgery.

Design: Randomized, double-blinded study.
