The pathological basis for cervicogenic headache may lie within the cervical spine. Clinically patients with cervicogenic headache complain of unilateral pain radiating in an atypical fashion from the occipital region. Our clinic has successfully treated post-traumatic cervicogenic headache with C2 spinal ganglion block. The technique of fluoroscopic guided injection was used to locate the C2 spinal ganglion. This technique is facilitated by the constancy of the anatomical relationship between the C2 ganglion and the midpoint of the atlanto-axial joint. There are no major structures near the proximity of the ganglion.

Cubital tunnel syndrome refers to compression neuropathy caused by pressure on the ulnar nerve pathway around the elbow. A 63-year-old male patient visited the clinic complaining of decreased sensation and weakness in his left ring finger and little finger, stating that the symptoms first began 6 months prior. He had undergone surgery to remove a ganglion cyst from his left elbow joint about 5 years prior in Mongolia. Magnetic resonance imaging revealed a cystic mass located at the previous surgical site, which was compressing the ulnar nerve within the cubital tunnel. Ulnar nerve decompression and anterior transposition were performed, and the cystic mass was excised. Upon pathological examination, the mass was diagnosed as a ganglion cyst. The patient's symptoms including sensory dysfunction and weakness improved over the 1-year follow-up period. This report describes a rare case of ganglion cyst recurrence compressing the ulnar nerve in the cubital tunnel after previous ganglion cyst excision.

The present study investigated inflammatory hypersensitivity following compression of the trigeminal ganglion in rats. Experiments were carried out on male Sprague-Dawley rats weighing 250-260 g. Under anesthesia, rats were mounted on a stereotaxic frame and injected with $8{\mu}L$ of 4% agar solution through a stainless steel injector to compress the trigeminal ganglion. In the control group, rats underwent a sham operation without agar injection. Injection sites were examined with a light micrograph after compression of the trigeminal ganglion. Air-puff thresholds (mechanical allodynia) were evaluated 3 days before surgery and 3, 7, 10, 14, 17, 21, 24, 30, and 40 days after surgery. Air-puff thresholds significantly decreased after compression of the trigeminal ganglion. Mechanical allodynia was established within 3 days and remained strong over 24 days, returning to preoperative levels approximately 40 days following compression. After subcutaneous injection of 5% formalin ($50{\mu}L$) in the compression of the trigeminal ganglion-treated rats, nociceptive scratching behavior was recorded for 9 successive 5-min internals. Injection of formalin into the vibrissa pad significantly increased the number of scratches and duration of noxious behavioral responses in sham-treated rats. Noxious behavioral responses induced by subcutaneous formalin administration were significantly potentiated in rats with trigeminal ganglion compression. These findings suggest that compression of the trigeminal ganglion enhanced formalin-induced infla-mmatory pain in the orofacial area.

Stellate ganglion block which usually practiced in pain clinics may combined with hemodynamic changes because it blocks sympathetic nerve chains. We measured the hemodynamic changes with NCCOM3-$R7^{(R)}$ (BOMED, U.S.A.) which applicated bioimpedance method in twenty-two patients. Mean arterial pressure, heart rate, cardiac output, ejection fraction and left ventricle end diastolic volume (LEDV) were measured before stellate ganglion block (control), 1, 3, 5, 10 and 20 minutes after stellate ganglion block with 8 ml of 0.25% bupivacaine. The results were as follows: Mean arterial pressure decreased significantly (p<0.05) in 10, 20 minutes after stellate ganglion block comparing to control, but not clinically significant. Heart rate, cardiac output, ejection fraction and LVEDV showed no significant change compared to control value. These results showed that stellate ganglion block is a safe technique without significant hemodynamic changes.

Background: Chemical lumbar sympathetic ganglion block could potentially be used to treat plantar hyperhidrosis; therefore, we analyzed the outcome of lumbar sympathetic ganglion block using alcohol for the treatment of plantar hyperhidrosis. Methods: Between March 1992 and June 2003, 356 patients with plantar hyperhidrosis underwent lumbar sympathetic ganglion block using alcohol. All 356 patients were followed up for 2 years and the results evaluated. There were 185 and 171 male and female patients, respectively, with a mean age of 25.1 years, ranging from 15.3 to 56.5 years old. Lumbar sympathetic ganglion block using alcohol was performed with fluoroscopic guidance under local anesthesia. Results: The recurrence rate after 2 years was 34%. Compensatory hyperhidrosis, ejaculation failure, lower back pain and genitofemoral neuritis developed as complications in 132, 4, 12 and 2 patients, respectively. Of the 356 patients, 65% were satisfied. Conclusions: Lumbar sympathetic ganglion block using alcohol is an effective and safe method for the treatment of plantar hyperhidrosis, but more information about the complications and relatively high recurrence rates should be provided to the patient.

Stellate ganglion block is frequently effective on the pain of head and upper extremities. However, if the degree and duration of pain relief does not increase with repeated blocks, we may consider the neurolytic procedure on the stellate ganglion. A patient sufferring from the pain in the region of ophthalmic branch of left trigeminal nerve and left eyeball region had been treated with stellate ganglion block. In spite of repeated blocks, the degree and duration of pain relief did not increase. We performed the radiofrequency thermocoagulation of stellate ganglion at the operation room under fluoroscopy. Patient got pain relief immediately after the procedure without any remarkable complication except a mild ptosis, which was shown before the procedure. We may give priority to radiofrequency thermocoagulation for stellate ganglion neurolysis due to its simplicity and safty.

The technique of the stellate ganglion block is widely used as it is relatively simple and safe. But it can cause severe complications because there are major blood vessels and nerves around the stellate ganglion. We practiced CPR because of the respiratory failure caused by severe hematoma in the neck following the stellate ganglion block. A 46-year-old male patient admitted to ENT department because of the both sudden sensorineural hearing loss that happened after URI. He was referred to Pain Clinic for further evaluation and treatment. We decided to block the stellate ganglion. We injected 6ml of 0.5% mepivacaine on both sides of the stellate ganglion. There were no blood aspiration and abnormal vital signs during the 30 minute observation, either. Three hours after he went to the private room, he had pain and edema in his neck, but no respiratory defficulty. But later, respiratory failure was suddenly followed. So we practiced CPR. We confirmed severe hematomas in the neck through CT scanning. Hematomas is removed and the ruptured blood vessels which is supposed to be muscular branch of vertebral artery is ligated under general anesthesia. The patient was discharged from hospital after the treatment of pneumonia and duodenal ulcer as complications. We recommand you to compress the block site more than five minutes and not to prick with the needle several times at one point to prevent the formation of hematomas.

편두통은 기전이 불분명하나 각종 신경전달물질이 작용하여 국소적인 혈관수축과 혈관확장을 일으킨다. 성상신경절차단은 뇌혈류의 증가, 신체항상성개선, 교감신경기능의 둔화등의 효과로 편두통의 치료에 있어서 의의를 갖는다고 사료된다. 그러나 아직 기전이 불분명하므로 이에 대한 더 많은 연구가 필요하다고 본다.

The ultrastructural changes of adrenal chromaffin cells and ganglion cells in the adrenal gland of vacor-induced diabetic Mongolian gerbils were studied by electron microscopy. After one month of vacor-induced diabetes, some chromaffin cells were filled with dense bodies and large cytosomes with formy contents. Most of degenerating axon terminals were observed on chromaffin cells. A few macrophages were found among chromaffin cells at one month after induction. Several of these macrophages were filled with numerous phagosomes. After one month of vacor-induced diabetes, the ganglion cells showed increase in numbers of dense bodies and degenerating dendrites compared with the normal ganglion cells. Both electron dense and lucent types of degenerating axon terminals were found in interstitial space of the ganglion cells. Degenerating unmyelinated and myelinted axons contained dense and lamellar bodies. The satellite cells and macrophages with engulfed degenerated axon terminals were observed. After three months of vacor-induced diabetes, the unmyelinated and myelinated axons showed degenerative changes, whereas no structural changes could be demonstrated in adrenal ganglion and chromaffin cells. The satellite cells and macrophages containing partially digested debris were still commonly observed in the interstitial space of adrenal medulla. These results suggest that the degenerative changes occur in the adrenal ganglion cells as well as adrenal chromaffin cells of vacor-induced diabetic Mongolian gerbils.
