1.Preclinical Trial of Radiation Synovectomy with Ho-166.
Korean Journal of Nuclear Medicine 1999;33(2):200-204
Rheumatoid arthritis(RA) is a chronic inflammatory disease of joints with proliferation of synovial epithelial tissue. Therapeutic approach of the RA consists of pharmacological and surgical interventions. Synovectomy is indicated in patients with progressive inflammatory signs and symptoms intractable to medical treatment including local intracavitary steroid injection. Recently, local injection of radionuclides which emit high energy beta rays are labeled with chemical compounds such as 90Y, 165Dy-ferric hydroxide macroaggregate and have been introduced as an alternative therapeutic modality to surgical synovectomy. Holmium-166 is one of beta emitter and Ho-166-chitosan complex was developed for radiation synovectomy. Preclinical trial is on-going at our hospital using Ho-166-chitosan. The procedure and methods of preclinical trial are discussed.

A Bednar tumor is a variant of dermatofibrosarcoma protuberans(DFSP). The clinical and histopathological findings of Bednar tumors are identical to DFSP except for the presence of melanin-containing cells scattered within the lesion, so called pigmented DFSP. The majority of Bednar tumors are seen as DFSP present as multinodular protuberant masses in the skin. They can also present as an atrophic depressed scar-like lesions without any nodularity. We report an uncommon clinical presented case of a Bednar tumor on the back in a 22-year-old female. She presented with an asymptomatic, firm, bluish, chestnut sized, depressed and atrophic lesion on the back which had been present for 6 years. A Histopathological examination revealed massive proliferation of spindle-shaped cells arranged in a tight storiform pattern mixed with scattered pigmented cells. On immunohistochemical staining, the tumor cells were positive for vimentin, a -l-antitrypsin, and CD34, but were negative for cytokeratin, neurofilament, and factor XIIIa. The majority of the tumor cells was negative and the pigment cells were positive for the S-100 protein. The patient was treated by a wide local excision of the lesion. There has been no evidence of recurrence after 20 months post-operative follow up.

The Arnold-Chiari malformation (ACM) is an anomaly of the hindbrain consisting of two components: a variable displacement of a tongue of tissue derived from the inferior cerebellar vermis in the upper cervical canal and a similar caudal dislocation of the medulla and fourth ventricle. Hydrocephalus and meningomyelocele are another abnormalities that associated frequently. We present a case of Arnold-Chiari malformation with hydrocephalus and meningomyeolcele and a brief review of the literatures was added.

Journal of the Korean Pediatric Society 1994;37(8):1149-1155
Apert syndrome is an uncommon, congenital disorder characterised by malformation of the skull, most often acrocephaly or oxycephaly, in association with symmetrical syndactyly of both hands and feet. It is due to disturbance in the growth of bone and soft tissue affecting principally the head, the hands and the feet. The original description was presented by Troquart in 1886, and acrocephaloyndactyly was named by Apert in 1906. Since then, more than 200 cases have been reported in the world upto 1970. Recently, we have experienced three for typical Apert syndrome and made a brief related literature review

Invasive aspergilosis or mucormycosis of the paranasal sinuses involving the cranial cavity is termed'rhinocerebral' mycosis, which is often difficult to differentiate from malignancy. Prognosis of rhinocerabralmycosis: is diastrous and usually fatal. The authors herein report 6 cases of rhinocerebral mycosis: two of themwe mucormycosis and four were aspiergillosis histopathologically. Main CT featurs are nodular mucosal thickeningin the multiple sits of the paranasal sinuses that extend to orbital apex or cavernosu sinus through focaldestruction of bony wall. In spite of their invasiveness beyond bony boundary, destruction is not so remarkableand it is always accompained by bony sclerosis. Awareness of these diseases and CT patterns discussed in thisreport should be helpful in leading to early biopsy and treamtent.

Peripheral arterial disease(PAD) is a major health problem in the elderly population, so prevalence of PAD is investigated using Edinburgh claudication questionnaire. Subjects were over 65 years old in the kyeongsan county. The prevalence of PAD was 9.0% in total population(8.5% in men, 9.3% in women). definite claudication was 3.9%, atypical claudication was 5.l%. and, grade 1 was 4.4%, grade 2 was 4.6%. The prevalence of PAD was increased with age but not statistically significant. There was no difference of PAD by gender and smoking. PAD was significantly associated with systolic blood pressure positively. But, unexpectedly, PAD was significantly associated with BMl negatively. PAD are important elderly health problem in the our country. so the etiology and preventive methods of PAD will be researched on our country population.

Sick sinus syndrome comprises a variety of conditions involving sinus node dysfunction and commonly affects elderly persons. Though sudden cardiac death accounts for as much as 15% of all cause mortality in uremia, requiring permanent cardiac pacing in end-stage renal disease hemodialysed patients are very few. Most cases of sick sinus syndrome are idiopathic, and the cause can be multifac- torial. A-V conducton defects were attributed to extensive metastatic calcifications, involving the cardiac skeleton, conservative to severe hyperparathyroidism and inadvertent use of calcitriol and calcium carbonate as phosphate binders. If optimal hemodialysis is provided, benefits of permanent pacing are equal in uremic or non uremic patients and pacemaker implantation should be instituted. We report a case of sick sinus syndrome derived in elderly patient on hemodialysis.
