Background: Cerebral palsy is due to static encephalopathy during perinatal period. Selective dorsal rhizotomy (SDR) involves selective division of posterior nerve roots to reduce spasticity and improve function in children with spastic cerebral palsy. Anesthesia during SDR must preserve muscle contraction in response to direct electrical stimulation of the dorsal nerve roots. We did this study to get the better management of anesthesia for SDR. Methods: Anesthetic records were reviewed for 16 patients who underwent SDR during January 1996 to August 1997. Demographic data; anesthetic drugs and doses; changes of vital signs and end tidal CO2; dorsal root stimulation; postoperative pain control were analysed. Results: The mean age of patients was 4.9+/-1.7 years old. The mean weight was 16.3+/-4.0 kg. The under 1 MAC concentration of isoflurane and 2~3 mcg/kg/hr fentanyl did not interfere with electrophysiologic monitoring. Esophageal temperature was increased significantly during electrical stimulation of dorsal roots. End tidal CO2 concentration had a tendency to increase after electrical stimulation too. Direct installation of 10~15 mcg/kg intrathecal morphine prior to dural closure, and postoperative 0.5 mcg/kg/hr fentanyl had a good postoperative analgesia without complication. Conclusions: Isoflurane and fentanyl during anesthesia, and intrathecal morphine with continuous infusion of fentany postoperatively are suggested a good anesthetic method for SDR.

Sudoriparous angioma is an unusual form of angioma with pain and hyperhidrosis. We present two cases of typical sudoriparous angioma. Case 1: 9-year-old female showed 0. 8 to 2. 0cm multiple dark brownish tender palpable hypertrichotic masses on the right lower leg after birth. Muscular atrophy and flexion contracture was also developed on the right lower leg for 2 years. Case 2: 4-year-old rnale showed 3 * 3cm tender elevated mass on the left shin after birth. Marked hyperhidrosis was developed when even slight pressure applied on the lesion in these cases. On histologic examination, these two cases showed proliferation of varible sized blood veasels hyperplasia and dilated hyperplastic eccrine glandular and ectopic adipose tissue on the mid and deep dermis. Muscular biopsy from case 1 showed fibrotic and degenerative change. Electromicroscopic examination done from case 1. The secretory epithelial cell of eccrine gland showed cytoplastic degradation and slight dilated intercellular canaliculi (Fig. 11). The lumen of subepithelial capillaries were dilated and some of endothelial cells showed degenerative changes evidenced by RER dilation, mitochondrial swelling and detachment from underlying tissue(Fig. l2). The cutaneous nerve showed many non-myelinated axons enclosed in cytoplasm of Schwann cells.

Hydrofluoric acid(HF) burn is characterized by progressive tissue necrosis and severe pain. A 31 year old employee in the semiconductor industry came in contact with the 50% aqueous HF through a pin hole in the thumb of his protective gloves. About 2 hours after exposure, h noted deep, severe burning, excruciating pain and svtelling of right thumb. Thereafter, clark bluish eclematous necrotic patches were visible through the nail plate and on the distal end of right thumb. Pain was not effectively relieved by digital nerve block.

Syringoma of the vulva is a rare disorder and limitation of the lesions to this site appears unique. Lesions can be clinically diagnosed without difficulty, since it is characterized by multiple, bilateral, asymptomatic skin-colored papules. Vuluar syringoma should be considered in the differential diagnosis of multicentric papular lesions of the vulva. The patient presented here is a 30-year-old healthy woman; lesions are multiple, biiateral, asymptomatic, angular or round, skin-colored to yellowish brown, firm papules localized on the vulvar region and showing a characteristic histologic findings.

Epidermal cysts may develop on any part of the body. Most of them are thought to occur following inflammation of the epithelium of the hair follicle. These found on the palm and sole where the hair follicle is absent have been considered to developmant of following a traumatic inclusion of the epidermis into the Dermis. Because only a few cases w re known to be related to preceding trauma, the latter assumption has been questioned. Reerly, the HPV-like virions and papillomavirus genus-speciric antigen were detected in the epicrml cyst of the sole in some reports. 1 our cases of plantar epidermal cyst were studied for the presence of human papillomavirus using conventional histologic and immunohistochemical examinator Histologic examination showed three characteristic findings, that is, intracytoplasmic eosinophil odies in the cyst wall, parakeratosis within the cyst caviti, and vacuolar structures disperse the wall and cavity. In all of the cases, immunohistochernical staining was positive for papule evirus antigen. These findings suggest an etiologic as.iation between the papillomavirus infection and plantar epidermal cyst.

Urticaria pigmentosa developed in twins at the age of 6 weeks. They have numerous round to oval shaped, discrete or confluent reddish brown colored macules over whole body surface and neither twin had vomiting, diarrhea, flushing or irritability. Their relatives are unaffected. Biopsy specimen of. back lesion showed. pooling of mast cells in the upper dermis, and electron microscopic examinattion revealed normal mast cells.
