Background & Object : Myasthenia gravis(MG) is an autoimmune disease due to binding of antibody to acetylcholine receptors on the muscle membrane. It is well known that other autoimmune diseases infrequently accompany myasthenia gravis. The aim of this study was to evaluate the clinical significance of associated autoimmune diseases(AAD) and compare prognosis between MG with AAD and MG without AAD. Method : A total of 65 MG patients(24 men and 41 women) were enrolled at this study. From the clinical records of these patients, we investigated the clinical characteristics and prognosis of MG with AAD and compared these data with those of MG without other such diseases. Results : AAD were found in 10 of 65 cases(15%). 9 cases of 10 MG with AAD were generalized MG type. The most common disease was thyroid disorder. The rate of AAD was higher in thymic abnormal patients. There was no significant remission rate difference between MG with AAD and MG without AAD, but the percentage of patients experienced crisis was higher in MG with AAD. Conclusion : The occurrence of AAD may suggest a more generalized autoimmune disturbance that could be associated with a less favorable prognosis.

Background: Elderly patients with acute myeloid leukemia (AML) have a poor outcome because of co-morbidities, poor tolerance to intensive chemotherapy and inherently more resistant disease. Clofarabine is a second generation nucleoside analogue which has shown promising activity in elderly patients with AML. This study was conducted to review the outcome of treatment with clofarabine in a group of such patients. Methods: The records of 5 elderly patients who were diagnosed to have AML and treated with clofarabine over a 12 month period were reviewed retrospectively. Results: There were 2 female and 3 male patients with a median age of 68 years (range 65-82). At the time of treatment, 2 patients had newly diagnosed AML not considered suitable for intensive therapy, while 3 patients had partial or no response to conventional chemotherapy. The overall response rate was 100%, all patients achieving a complete remission. Induction and consolidation were well tolerated. All patients developed neutropenia with a median duration of 20 days (range 17-42). One patient developed hand and foot syndrome and a generalized rash but recovered. There was no mortality and all patients remained in remission after a median follow-up of 5.2 months (Range 3-10). Conclusion: Clofarabine (alone or in combination) is active in elderly AML patients with an acceptable safety profile and should be considered a potential option in this group.

Objectives The purpose of this study is to obtain knowledge from clinical studies conducted in China to examine the effectiveness of herb medicine in childhood acute leukemia. Methods We searched the randomized controlled trials (RCTs) with herbal medicine treatment on childhood acute leukemia from the 'CAJ', Chinese Academic Journal from China National Knowledge Infrastructure (CNKI). And then, demographic data, duration of illness, intervention, treatment period, outcome, adverse events, and composition of herbal medicine were analyzed for this study. Result 10 RCT studies were selected and analyzed. The control group were given western medicine therapy, the treatment group was given herbal medicine on the basis of the control group. The most commonly used herbal medicine were 淸熱解毒藥, 補氣藥, 補陰藥, 活血祛瘀藥 in 'boosting vital force and driving out evil spirit (扶正祛邪)' way to 'relieve heat (熱毒)' and 'assist the vital force (正氣)'. In the treatment group, complete remission was significantly higher than control group and the decrease in TCM syndrome scores also showed significant effects. Adverse events were significantly lower in the treatment group. Conclusions Herbal medicine treatment on childhood acute leukemia can be suggested as a new treatment for children who have less response to the conventional therapy, and can supplement the limitations of the western medicine by increasing complete remission and reducing adverse events.

Hyperthyroidism, characterized by elevated thyroid hormone levels and thyroid gland hyperplasia or adenoma, is a prevalent endocrinopathy in older cats. Treatment options include antithyroid drugs, surgical thyroidectomy, and radioiodine therapy (RAIT), which is non-invasive treatment option that can achieve complete remission. However, efficacy and safety of RAIT in hyperthyroid cats have not been investigated in South Korea. This study includes 10 hyperthyroid cats with RAIT. Initial assessments comprised history, physical examination, blood analysis, and serum total T4 (tT4) concentration. Thyroid scintigraphy revealed hyperactivity and enlargement of thyroid gland at 24 hours before the RAIT. Radioiodine (RAI) was injected subcutaneously with 2 to 6 mCi, determined by the fixed dose or the scoring system based on severity of clinical signs, tT4 concentration, and thyroid size individually. After RAIT, the concentration of serum tT4 and liver enzymes were significantly decreased at discharge. However, no significant differences were noted in blood urea nitrogen, creatinine, symmetric dimethylarginine, hematocrits, and white blood cell counts pre- and post-treatment. Although 4 cats received RAI twice, clinical signs disappeared and tT4 levels decreased following the RAIT. All 10 cats achieved complete remission after 6 months without critical adverse effect. The safety and the effectiveness of RAIT was confirmed based on protocols reported other countries. Therefore, RAIT could be considered the treatment option and prevent adverse effects from medication or surgery. This preliminary study presents the first evaluation of RAIT for hyperthyroid cats using locally produced RAI in South Korea and provide valuable insight for clinicians and further studies.

Dense deposit disease (DDD) is a rare disorder characterized by the deposition of abnormal electron-dense material within the glomerular basement membrane of the kidneys. The diagnosis is made in most patients between 5 and 15 years of age, and within 10 years, approximately half of the affected patients progress to end-stage renal disease. We report a rare case of regressive DDD without C3 deposition after steroid therapy in an 11-year-old boy. The patient presented with edema, gross hematuria, and nephrotic-range proteinuria. Laboratory testing revealed a serum creatinine level of 1.17 mg/dL, albumin level of 2.3 g/dL, and serum C3 level of 125 mg/dL (range 90-180 mg/dL). The results of the renal biopsy were consistent with DDD without C3 deposition. After 6 weeks of steroid therapy, the nephrotic syndrome completely resolved. The follow-up renal biopsy showed a significant reduction in mesangial proliferation and disappearance of electron-dense deposits in the GBM.

목적 : 막성 신병증은 소아에서 드문 신질환이다. 저자들은 일차성 막성 신병증의 임상 경과의 이해와 치료 방침의 결정에 도움을 주고자 일차성 환자들을 후향적으로 고찰하였다. 방법 : 1977년부터 2003년에 소아 막성 신병증 환자 58명 중 42명(72.4%)이 B형 간염 연관성이었고, 16명(27.6%)이 일차성이었다. 2000년 이후 진단된 환자는 모두 일차성이었다. 임상-병리학적 소견(성별, 연령, 단백뇨, 혈청 알부민, 콜레스테롤, 크레아티닌 청소율, 신세뇨관-간질 변화, 신사구체 경화증, 고혈압, 신정맥혈전증, ACE inhibitor 및 면역억제제 사용력)을 조사하였고, 관해군과 비관해군 간 비교를 하였다. 결과 : 남자 6명, 여자가 10명이었고, 진단 시 중앙 연령은 13세 5개월이었다. 발현 증상은 신증후군(7명, 43.8%), 육안적 혈뇨(5명, 31.3%)와 현미경적 혈뇨 및 단백뇨(3명, 18.8%)였다. 고혈압(2명, 12.5%), 신정맥 혈전증(2명, 12.5%)과 저칼슘성 테타니(1명)가 동반되었다. 조직소견 상범사구체성(6명, 37.5%) 또는 분절성 경화증(5명, 31.3%), 반월체(1명)와 경도(11명, 68.7%) 또는 중등도의 신세뇨관-간질 변화(3명, 18.8%)가 보였다. 13명(86.7%)이 스테로이드를 투여 받았고, 이 중 2명은 cyclophosphamide, 1명은 cyclosporin을 투여 받았다 10명(52.5%)은 ACE inhibitor를 투여받았다. 진단 1개월 후 누락된 1명을 제외하고, 7명(46.7%)에서 단백뇨가 소실되었고, 8명(53.3%)은 단백뇨가 지속되었으며, 그 중 2명(13.3%)은 만성신부전으로 진행하였다. 관해군과 비관해군간에 임상-조직 병리학적 소견은 유의한 차이가 없었다. 결론 : 우리나라 소아에서 막성 신병증은 일차성이 막성 신병증의 대부분을 차지하게 되었는데, 그 이유는 B형 간염 예방 접종 도입 이후 B형 간염 연관성 막성 신병증이 현저하게 감소하였기 때문이다. 이 질환의 임상 경과의 이해와 치료 방침의 확립을 위해서 다기관의 전향적 연구가 필요하다.

아급성 독성 시험으로부터, 미립구내의 레티노익 산을 기준으로 한 투여량이 100mg/kg 일때는 4마리의 치사 개체가 보이는 등의 심각한 독성 효과가 유발되었으며, 25 및 50mg/kg인 경우에 독성 효과가 거의 나타나지 않음을 관찰하였다. 50mg/kg의 투여량의 경우, 일부 동물에서 뼈골절 현상이 나타났지만, 이러한 독성효과는 항염증제를 같이 투여함으로써 극복될 수 있을 것으로 생각되어졌다. 따라서, 앞으로의 실험에서는 항염증제를 이용하여, 가능한 독성을 억제하연서, 보다 빠른 기간 내에 상태가 회복될 수 있도록 하는 연구를 행할 것이다.

Objective: This study aimed to investigate the effect of multimodality treatment of advanced paediatric hepatoblastoma (HB) and the factors affecting prognosis. Methods: A total of 35 children underwent multimodality treatments consisting of chemotherapy, surgery, interventional therapy, and autologous peripheral blood stem cell transplantation. The patients were followed up every month. Results: Serum AFP levels in 33 out of 35 patients in this study were significantly increased (P = 0.0002). According to the statistical scatter plot, the values of serum AFP on the 25th, 50th, and 75th percentages were 1,210, 1,210 and 28,318 ng/dl, respectively. Of the 35 cases, 21 were stage IV. 18 cases were treated with systemic chemotherapy before surgery, and 3 cases with locally interventional chemotherapy before surgery. Statistical analysis showed that the preferred interventional treatment affected prognosis, and that there was a statistically significant difference (P = 0.024). Some 33 patients completed the follow-up, of which 17 were in complete remission (CR), 5 were in partial remission (PR), 1 became disease progressive (DP), and 10 died. The remission and overall survival rates were 66.7% (22/33) and 69.7% (23/33), respectively. Patients with the mixed HB phenotypes had worse prognoses than the epithelial phenotype (P < 0.001), and patients in stage IV had a lower survival rate than those in stage III (P < 0.001). Conclusion: Multimodality treatment can effectively improve remission rate and prolong the survival of children with advanced HB. In addition, alpha-fetoprotein (AFP), a tumor marker of liver malignant tumors, HB pathological classification, and staging are highly useful in predicting prognosis.
