  • Recently, combination of surgery and radiation therapy (RT) has been recommended in the treatment of craniopharyngioma. RT could be associated with late complications, including vasculopathy. We report two cases of the moyamoya syndrome seen in children with craniopharyngioma who received RT after surgical resection. Thirty-five patients in pediatric age with craniopharyngioma were surgically treated. Fifteen out of 35 patients underwent surgical resection followed by RT or gamma knife surgery. Two of the 15 were found to have symptoms of transient ischemic attack and were diagnosed as moyamoya syndrome through the cerebral angiography. Age at RT was 4 and 13 years, respectively. The latent period for development of the moyamoya syndrome was 27 months and 3 years, respectively, after RT. The RT dose of both patients was 54 Gy. These two patients received bilateral encephaloduroarteriosynangiosis procedures. We report here these two cases of radiation-induced moyamoya syndrome in pediatric craniopharyngioma. Pediatric patients with craniopharyngioma who received RT should be reminded, during follow-up, about the risk of development of the moyamoya syndrome.

  • Chordoma is a malignant tumor arising from the primitive notochord involving the axial skeleton. It usually occurs at sacrococcygeal and besisphenoidal area but only rarely does at other vertebral areas, especially at the thoracic vertebrae. It has a slow growth rate and is locally aggressive with an extremely high rate of local recurrence. Either surgery or radiation alone often fails to cure the disease and the local failure is the main cause of treatment failure and death. Overall 5 year survival rate is less than $10\%$. Useful palliation or occasional cure can be obtained by the combination of surgery and radiotherapy. After incomplete resection, the tumor requires radiation dose of 7,000 cGy or more over 6-7 weeks for local control. Tumor regression is slow in response to irradiation and continuation of the regression for several months after completion of RT is not unusual. We report a case of chordoma of the thoracic vertebra, the site of extreme rarity, which showed good local control after partial resection and radiation therapy. He is well and alive without any evidence of recurrence after 13 months of treatment with near complete tumor regression.

  • Purpose: Livedo vasculitis is recurrent painful ulceration of the feet, ankles and legs characterized by purpuric papules and plaques that undergo superficial necrosis and healing with residual white atrophic scars (atrophie blanche). The typical histopathologic findings of livedo vasculitis are characterized by endothelial proliferation and hyaline degeneration along with thrombosis of dermal vessels. Standard therapeutic strategies for treatment of livedo vasculitis are usually on the basis of rheologic, anti-inflammatory or immnosuppressive treatments, a aspirin, dipyridamole, glucocorticosteroids, pentoxyfylline, or high-dose intravenous immunoglobulin are often ineffective or partially effective. Methods: We report a case of 24-year-old male patient with livedo vasculitis on the ankles and dorsal surfaces of both feet. Results: The lesion that had been unresponsive to medical treatment were successfully healed with complete debridement and skin grafting without recurrences. Conclusion: Surgical treatment can be one of the therapeutic choice in Livedo vasculitis.

  • The main route of metabolism of isonicotinic acid hydrazid (INH) in man is its conjugation with acetyl coenzyme A to form acetyl-INH. The reaction is catalyzed by an N-acetyl transferase in the liver. The acetylated drug can be excreted by the kidney more efficiently than INH, and the biological half-life of the drug in the body depends upon how rapidly the drug can be acetylated. This report measured the concentration of INH in the blood of 147 individuals 6 hours after they received a standard dose (9.8mg/kg) and plotted the data as a frequeney distribution hiotogram. There was bimodality, with a mean for one subpopulation at approximately $0.6{\sim}0.8\;mcg/ml.$, and a mean for the other subpopulation between 2.8 and 4.0mcg/ml. As might be expected slow acetylators of INH are more likely to develop a cumulative toxicity to the drug. The principle ,toxicity to INH is a peripheral neuritis but this adverse effect can be prevented by given extra pyridoxin to the patients, and the vitamin does not alter the antitubercular activity of INH. This report carried out that pyridoxine does not alter the ratio of free INH to the total INH in blood.

  • Chemotherapy has many known side effects. Neuropathy is a common side effect when using cisplatin. The clinical course varies and depends on the agents used and their cumulative dose. Although symptoms can resolve completely, in most patients chemotherapy-induced peripheral neuropathy is either only partially reversible or completely irreversible. Current management for chemotherapy-induced peripheral neuropathy is symptomatic relief using membrane stabilizing medications and antidepressants. Dysaesthesia and pain involving the feet and hands are described in traditional korean medicine. In traditional korean medicine, the pathogenesis is related to the inability to direct Qi and Blood to the extremities, and is associated with Qi, Blood, Yang and Kidney deficiencies. We report a case of a 52 years old female patient treated with acupuncture and bleeding treatment for the goal of improving the symptoms of chemotherapy induced peripheral neuropathy. Further study and other medical method will be needed in order to improve the effect and determine the long-term effect of traditional korean medicine in treating Chemotherapy-induced Peripheral Neuropathy.

  • Objective : Base on clinical practice, the authors report a case of tardive dyskinesia arising during the course of treatment with resperidal. Methods : This article was review and analysis of a case on risperidone-induced tardive dyskinea. Results : Mrs K, a 51-year-old woman with a 1-year history of schizophrenic disorder, gradually developed tardive dyskinetic movement of the mouth, lip, and tongue over a 4 month period(From July, 1996 to June, 1997) while taking risperidone. Initially she was treated with haloperidol and alprazolam. However, the haloperidol was subsequently discontinued because of EPS developed. From 11th March, 1997, she was observed to have a severe form of tardive dyskinesia involving her tongue, lip, and mouth. After risperidone was withdrawn at 9th May 1997, her tardive dyskinetic movement was disappeared. Conclusions : This is, to our knowledge, the first report of the onset of tardive dyskinesia in a patient taking risperidone. However, additional controlled studies of specific questions are needed ; e.g., the dose-response curves for produce tardive dyskinesia and the mechanism of producing risperidone-induced tardive dyskinea and so on.

  • Infection cases of diphyllobothriid tapeworms are not much in the below teen-age group. We report a case of Diphyllobothrium nihonkaiense infection in a 13-year-old boy. He presented with severe fatigue, occasional abdominal pain at night time. He also had several episodes of tapeworm segment discharge in his stools. By his past history, he had frequently eaten raw fish including salmon and trout with his families. Numerous eggs of diphyllobothriid tapeworm were detected in the fecal examination. We introduced amidotrizoic acid as a cathartic agent through nasogastroduodenal tube and let nearly whole length (4.75 m) of D. nihonkaiense be excreted through his anus. After a single dose of praziquantel, the child's stool showed no further eggs, and his symptoms disappeared. The evacuated worm was identified as D. nihonkaiense by mitochondrial cox1 gene analysis. Here we report a successful extracorporeal worm extraction from an infection case of D. nihonkaiense by the injection of amidotrizoic acid.

  • The fur mite is a highly contagious zoonotic mite that causes skin disorders in rabbits. In this case report, four rabbits with a fur mite infestation were treated with a single dermal application of permethrin (65%) at a dose of 0.1 ml. All the rabbits were treated successfully with permethrin without any adverse reactions at 8 weeks after treatment. This suggests that permethrin is an effective treatment for fur mite infestations in rabbits.

  • Hemophilia A is the most common congenital bleeding disorder, which is sex-linked disease, caused by a deficiency of clotting factor VIII. We experienced a case of alveolorrhaphy using iliac bone graft under general anesthesia for the correction of bilateral cleft alveolus in 10-year-old boy with hemophilia A. Factor VIII activity in this patient was 0.7%, on the severely deficient level, and aPTT was 100 seconds. Just before operation, he received 1,750 units of factor VIII intravenously for loading dose. After we confirmed his factor VIII activity improved to 95% and aPTT to 38.4 seconds, operation was begun. No more transfusion was needed during the operation. In his postoperative care, he received 50 units/kg a 12 hours for 3 days and 30 units/kg a 12 days for 2 days. His factor VIII activity was maintained at 57-139% during his hospitalization. He was discharged without any anesthetic complication. So we report this successful case of anesthetic management for the oral surgery in a child with hemophilia A.

  • Congenital hyperinsulinism (CHI) is a rare condition that can cause irreversible brain damage during the neonatal period owing to the associated hypoglycemia. Hypoglycemia in CHI occurs secondary to the dysregulation of insulin secretion. CHI has been established as a genetic disorder of islet-cell hyperplasia, associated with a mutation of the ABCC8 or KCNJ11 genes, which encode the sulfonylurea receptor 1 and the inward rectifying potassium channel (Kir6.2) subunit of the ATP-sensitive potassium channel, respectively. We report the case of a female newborn infant who presented with repetitive seizures and episodes of apnea after birth, because of hypoglycemia. Investigations revealed hypoglycemia with hyperinsulinemia, but no ketone bodies, and a low level of free fatty acids. High dose glucose infusion, enteral feeding, and medications could not maintain the patient's serum glucose level. Genetic testing revealed a new variation of ABCC8 mutation. Therefore, we report this case of CHI caused by a novel mutation of ABCC8 in a half-Korean newborn infant with diazoxide-unresponsive hyperinsulinemic hypoglycemia.
