Overall complication rates of 9.1% have been reported following implantable cardioverter defibrillator (ICD) placement. Brachial plexus injury is infrequently reported in the literature. We describe a 26-year-old female experiencing left arm nerve pain, a positive Tinel's sign, numbness in the median nerve distribution of the hand and biceps muscle weakness following revision ICD via subclavian vein approach. Nerve conduction studies identified severe partial left brachial plexopathy, which remained incompletely resolved with conservative management. Surgical exploration revealed lateral cord impingement by the ICD generator and a loop of the ICD lead, along with fibrosis, necessitating surgical neurolysis and ICD generator repositioning. As increasing numbers of patients undergo cardiac device implantation, it is incumbent on practitioners to be aware of potential increases in the prevalence of this complication.

Endothelin has $ET_{A}$ type and $ET_{B}$ type receptors, and it has been thought that ET-1 proves vasoconstriction effect via $ET_{A}$ receptor and vasodilation via $ET_{B}$ receptor. Recently, it has been reported that $ET_{B}$ receptor is also related to the vaso-constriction. Bosentan is a $ET_{A+B}$ receptor antagonist, and proves it's effect on trauma and ischemia. We already announced that the level of Endothelin-1 increase in the brain and spinal cord of EAE-induced lewis rat and showed the origin of ET-1 is activated macrophages. Intracisternal injection of Bosentan, $ET_{A+B}$ receptor antagonist, (300nmol/body) was done for observing the role of endothelin-1 on the pathogenesis of EAE. Bosentan ameliorated the severity of clinical score of EAE and decreased the histologically observed inflammatory region. The blocking effect on the progression of EAE model suggests that Bosentan is a physiological antagonist in terms of development of the sign of multiple sclerosis.

Objectives : The purpose of this study is to examine whether Eucommiae Cortex pharmacopuncture may affect to the neuropathic pain in a rat model. Methods : To produce the model of neuropathic pain, under isoflurane 2.5 % anesthesia, underwent tight ligation by 6.0 silk thread and transection of the tibial and sural nerves, leaving the common peroneal nerve intact. After neuropathic surgery, the author examined if the exhibited the behavioral sign of allodynia. The allodynia was assessed by stimulating the plantar with Dynamic Plantar Aesthesiometer. Three days after the neuropathic surgery, Eucommiae Cortex pharmacopuncture was injected at Sinsu($BL_{23}$) once every week for 6 weeks. After that, the author examined the withdrawal response of neuropathic rats' leg by Dynamic Plantar Aesthesiometer. And also the author examined Bax, Bcl-2, Bax/Bcl-2 ratio in the spinal cord of neuropathic rats and the change of WBC, RBC, HGB, HCT count in the blood of neuropathic rats. Results : 1. The Eucommiae Cortex pharmacopuncture decreased the withdrawal response of mechanical allodynia that assessed with Dynamic Plantar Aesthesiometer in EC2-$BL_{23}$ group as compared with control group. 2. The Eucommiae Cortex pharmacopuncture decreased Bax/Bcl-2 ratio in EC1-$BL_{23}$, EC2-$BL_{23}$ group. But The Eucommiae Cortex pharmacopuncture injected at Sinsu($BL_{23}$) didn't change Bax, Bcl-2 expression level in the all group. 3. The Eucommiae Cortex pharmacopuncture decreased WBC count in EC1-$BL_{23}$, EC2-$BL_{23}$ group. Conclusions : We have noticed that Eucommiae Cortex pharmacopuncture decreased mechanical allodynia in the model of neuropathic pain compared with the control group. Bax/Bcl-2 ratio in spinal cord of that group was also decreased compared with the control group. This study can be used as a basic resource on a study and a treatment of neuropathic pain.

Purpose: Microcystic adnexal carcinoma is a rare malignant appendage tumor, first described by Goldstein et al in 1982. Here, we present our experience in treatment of a case on the lower lip. Methods: A 52-year-old female with an asymptomatic nodule on the chin, previously misdiagnosed as trichoadenoma by needle aspiration biopsy, was treated by wide excision combined with multiple circumferential frozen biopsies. Results: Pathological examination revealed typical features of microcystic adnexal carcinoma, such as basaloid and squamous cells forming nests and cord-like patterns, horn cysts, and minimal cytologic atypia. The patient has been followed up for 6 months. No sign of recurrence is noted to date. Conclusion: Differentiation from other benign adnexal neoplasms is important for its appropriate treatment. Differentiation can be difficult histologically because it is difficult to acquire an adequate biopsy due to its invasiveness, and clinically due to its asymptomatic and slow growing features. Complete excision is the key treatment, but it may not always be the best solution considering the huge defect that may result and the low incidence of metastasis & deaths owing to the tumor. We add this case to the approximately 300 cases reported worldwide with a review of literature.

Signalment: A 7-month-old, female domestic shorthaired cat was presented for acute pelvic limb paraparesis. Results: There was no abnormality on survey radiographs and blood analysis, however neurological examination revealed proprioception positioning and hopping was absent in the pelvic limbs. Also, anal tone and perineal sensation were reduced. Magnetic resonance (MR) imaging showed nucleus pulposus dehydration and disc protrusion at T12-T13. Ill-defined diffuse lesion was found at T10-L2 level and it showed isointense on T1-weighted images and hyperintense on T2-weighted and FLAIR images. This lesion was considered as edematous lesion secondary to disc protrusion. The presumptive diagnosis was focal spinal cord edema associated with intervertebral disc protrusion. A traumatic aetiology was suspected. The cat was treated corticosteroids and analgesic and clinical sign improved following 9 days of treatment. Clinical relevance : Intervertebral disc protrusion is rare disease in a cat. However, it could be considered as a cause of paraparesis in cats.

The most common cause of foot drop is lumbar degenerative disc herniation, particularly at L4/5. We present a rare case of spinal cord injury accompanied by a thoracolumbar lesion that presented with bilateral foot drop. A 69-year-old male patient presented with sudden-onset severe bilateral leg pain and bilateral foot drop. Radiologic findings revealed T12 spondylitis compressing the conus medullaris. He had undergone vertebroplasty for a T12 compression fracture after a fall 6 months before. A physical examination showed bilateral foot drop, paresthesia of both L5 dermatomes, increased deep tendon reflex, and a positive Babinski sign. An acute bilateral L5 root lesion and a conus medullaris lesion were suspected based on electromyography. A surgical procedure was done for decompression and reconstruction. After the operation, bilateral lower extremity muscle strength recovered to a good grade from the trace grade, and the patient could walk without a cane. The current case is a very rare report of bilateral foot drop associated with T12 infectious spondylitis after vertebroplasty. It is essential to keep in mind that lesions of the thoracolumbar junction can cause atypical neurological symptoms. Furthermore, understanding the conus medullaris and nerve root anatomy at the T12-L1 level will be helpful for treating patients with atypical neurological symptoms.

Objectives : The purpose of this study was to evaluate the clinical features of the epidermoid tumor of posterior fossa and to assess the surgical outcome. Methods : We reviewed the clinicoradiological records of 10 epidermoid tumor of posterior fossa, treated surgically at our hospital between 1991 and 1996. Results : The mean age of onset was 36 years old and mean duration of symptom was 5.2 years. Six were men and four were women. The location of tumors were cerebellopontine angle(CPA) 5 cases, cerebellum(Cbll)& 4th ventricle 3 cases, foramen magnum 1 case, and pineal region extended to Cbll and 4th ventricle 1 case. Common clinical features were trigeminal neuralgia in 3 cases, cerebellar signs 2 case, headache 2 cases, hemifacial spasm with deafness 1 case, cbll signs and multiple cranial nerve dysfunctions 1 case. One CPA epidermoid had no clinical symptom and sign associated with the tumor. The surgical approaches were suboccipital approach in 9 cases and one transcallosal approach to the tumor of pineal region. The extent of surgical removal was gross total resection in 5 cases and near total or subtotal resection in 5. Two patients with CPA tumor were complicated with facial paresis. One patient with tumor located in cerebellum extended into cisterna magna had postoperative vocal cord paresis. All complicated cases had severe adhesion of tumor capsule with brainstem or cranial nerve. The mean duration of follow up was 26 months. The overall outcome was improvement of symptoms and signs in 6 cases and stationary 4 cases. During follow up, imaging study was done in 7 patients and none of them had finding of tumor recurrence. Conclusion : We conclude that recurrence of tumor is rare in both total and subtotal resected cases, but long-term follow-up is required. Aggressive removal of tumor capsule that adhesed to brianstem or cranial nerve is avoided for preventing severe postoperative complication.
