Writer's cramp is a gradual onset and the disorder shows itself at first only when the pa- tient is fatigued or stressed, or when a difficulty in controlling the pen leads to inaccurate writing. The prognosis is poor and treatment is often difficult and unsatisfactory. We have administered stellate ganglion block for a treatment of writer's cramp. Case l: A-30-year old male, who had a difficulty in writing with palpitation for 10 years in front of the other men. After 5 times of stellate ganglion block, palpitation during writing did not appear and after 15 times, he could write with a slight spasm of hand muscles. Case 2: A-40-year old male, who had a difficulty in writing in a stressful situation. After 28 times of stellate ganglion block, he could write in normal work except in the strong stressful situation. From our experience, we recommend the stellate ganglion block may be an effective treat- ment for a writers cramp.

Impairment of erectile function, although normally a benign disorder, has a profound impact on the well-being of many men. Penile erection is produced by a complex series of events involving cognition, peripheral sen- sory input, central and peripheral autonomic nervous events and hormonal vascular events. The multiplicity of potential determinants identified suggest that impotence does not inex- orably accompany age, but it is an arugmented significantly modifiable paraaging phenomena. A 53 year old male patient developed sudden impotence. The patient did not respond to intracavernous injection of papaverine. This patient was successfuly treated with 4 repeated stellate ganglion blocks.

기관지 천식 환자의 치료에 성상신경절 차단 효과 - 3예 보고 -

Asthma is a disease of the airways that is characterized by increased responsiveness of the tracheobronchial tree to a multiplicity of stimuli. A number of causes have been postulated for the increased airway reactivity of asthma. However, their basic mechanism remains unknown. The treatment of bronchial asthma is conservative as beta-adrenergic agonist, methyl- xanthines, glucocorticoids, anticholinergics and mast cell stabilizing agent. Stellate ganglion block for the treatment of bronchial asthma has its controversies. Stellate ganglion block was performed for the treatment of 3 patients with bronchial asthma. After stellate ganglion blocks, dyspnea, coughing and wheezing was markedly reduced. Lung function test improved with 1 st case. Two asthma cases were able to discontinue med- ication for asthma. No severe aggrevation of bronchial symptoms were noted after stellate ganglion blocks. It sugRested that stellate ganglion block can be safely performed on bronchial asthmatic pa- tients

불인성 미골통에 Caudal Epidural Steriod 이용 -증례보고-

안명자,서재현,김성년,Ahn, Myung-Ja,Suh, Jae-Hyun,Kim, Sung-Nyeun 대한통증학회 1992 The Korean Journal of Pain Vol.5 No.1

Coccygodynia is a pain syndrome resulting from trauma, fractures, infection and tumor, and is usually amenable to conservative treatment. We present one case of coccygodynia that developed 2 days after percutaneous cordotomy done for pain control of cervix cancer unresponsive to conservative treatment which subsequently was treated with a caudal injection of lidocaine and triamcinolone. Caudal epidural steroid injection is less invasive and has less potential for complication than the neurosurgical interruption of the pain pathway.

한국방송(KBS)은 전자통신연구원(ETRI)과 공동으로 송수신 안테나의 낮은 분리도(isolation)하에서도 운용이 용이하며 중계기 내부의 왜곡을 보상할 수 있는 DOCR(Digital On-Channel Repeater)을 개발하였다. 개발된 DOCR의 성능과 서비스 커버리지를 측정하기 위하여 수원 지역에서 2004년과 2005년 두 차례의 필드테스트를 공동으로 실시하였다. 본 논문에서는 개발된 DOCR시스템에 대하여 그 특징을 설명하고 수원 지역에서 실시된 필드테스트 결과를 분석한다. 또한, 다양한 세대의 ATSC 수신기를 측정에 사용함으로써 수신기 성능에 따른 DOCR 서비스 커버리지의 변화를 측정하였다. 측정결과에는 DOCR의 사용에 따른 수신성공률, 수신마진, 수신용이성(수신가능각도)등이 포함되며 측정 지역의 수 년간의 테스트 결과를 종합하여 서비스 범위내의 수신성능을 분석한다.

양측 상박 신경총 침범으로 불인성 통증을 동반한 폐암환자의 통증치료 경험

Severe intractable pain with paresthesia and severe dyspnea produced by lung cancer involv- ing both brachial plexuses, refractory to ordinary pharmacologic approaches, was managed by epidural morphine and bupivacaine administration with the continuous Baxter infusion system. Chest pain, which is somatic pain in character, was well managed with the epidural morphine and bupivacaine administrations. However paresthesia and tingling sensation of the hand and forearm were poorly controlled by epidural morphine, and were finally managed by bolus epidural injections of bupivacaine. Supportive therapy included epidural steroid injection and TENS, but the effect was not satis- factory. Severe dyspnea seemed to aggrevate cancer related pain.

경막외 Droperidol 투여로 발생한 Neuroleptic Malignant Syndrome - 1예 보고 -

안명자(Myung Ja Ahn),서재현(Jae Hyun Suh),김성년(S 대한통증학회 1991 The Korean Journal of Pain Vol.4 No.1

N/A The neuroleptic malignant syndrome (NMS) is an uncommon but dangerous complication of treatment with neuroleptic drugs. This syndrome is characterized by autonomic dysfunction, extrapyramidal dysfunction, and hyperthermia. NMS seems more frequent with parentral neuroleptic use. We report a patient in whom suspicious NMS was developed in the ward after epidural administration of 2. 5mg of droperidol with morphine for postoperative pain control. Extrapyramidal symptoms and autonomic dysfunction were treated with diazepam, but tem- perature was spontaneously deereased after l6 hours and 40 minute after receiving epidural droperidol.

토끼에서 경부 교감신경절의 무수 에틸 알코올에 의한 화학적 차단

N/A Blockade of cervicothoracic sympathetic ganglion (stellate ganglion controls pain on face, head, neck, shoulder, upper limbs, and upper chest, including their viscera and sympathetically maintained pain. This procedure also increases blood flow to the above areas and relieves hyperreactivity of sympathetic nervous system. Clinically, repeated stellate ganglion blocks with local anesthetic agent may become difficult with complications such as accidental intravascular or subdural injection, recurrent laryngeal nerve or bracheal plexus paralysis, pneumothorax and edema on injection site. Therefore, at times long-term cervicothoracic ganglion block with neurolytics is necessitated but its applica- tions are prohibited by the critical structures surrounding ganglion. There are also few reports of neurolytic stellate ganglion block. This study was performed to observe the complications, gross changes of surrounding struc- tures, and microscopic findings of ganglion cells after neurolytic block and to certify the possi- bility of clinical use of neruolytic stellate ganglion block. The unilateral superior cervical sym- pathetic ganglion of rabbit was blocked with absolute ethyl alcohol 0.4 ml at the level of cricoid cartilage. Normal ganglion was used as a control and 5 animals were sacrificed at each inter- vals of 7, 15 and 50 days after block. The results were as follows; 1) All experimental animals showed no specific changes of behavior, motor function. No ne- crotic tissues were present in the block area during the observation period. There were some gross scar tissues along the fascia of muscles surrounding the needle injection site, but gross atrophy of muscles or injured major vessels were not found. 2) Microscopically, structures of normal ganglion of rabbit were very similar to those of hu- mans. Seven days after absolute ethyl achohol injection there were marked edema of ganglion cells and nuclei with irregular nuclear membrane. Some of the ganglion cells lost their nuclei and showed degenerative changes. Fifteen days after block, cell edema were decreased and loss of the Nissl's body was prominant. The ganglion cell structures looked close to normal but the cytoplasm and nucleus were generally contracted 50 days after block. These results suggest absolute ethyl alcohol injection on cervical sympathetic ganglion with above method mainly blocks pre- and post-synaptic fibers and the long-term neurolytic block- ade of this ganglion may be possible in rabbits.
