  • Purpose: The purpose of this study was to determine the frequency of $CD4^+CD25^+FoxP3^+$ regulatory T cells (Treg) in the peripheral blood of patients with childhood chronic immune thrombocytopenic purpura (ITP) exhibiting thrombocytopenia and spontaneous remission. The findings of this study indicate the possibility of predicting spontaneous recovery and pathogenesis of childhood chronic ITP. Methods: Eleven children with chronic ITP (seven thrombocytopenic and four spontaneous remission cases; mean age, 8.8 years; range, 1.7-14.9 years) were enrolled in this study. Five healthy children and eight healthy adults were included as controls. The frequency of Treg was evaluated by flow cytometry in the peripheral blood. Results: In this study, four patients (36%) achieved spontaneous remission within 2.8 years (mean year; range, 1.0-4.4 years). The frequency of Treg was significantly lower in patients with persisting thrombocytopenia ($0.13%{\pm}0.09%$, P<0.05), than that in the patients with spontaneous remission ($0.30%{\pm}0.02%$), healthy adults controls ($0.55%{\pm}0.44%$), and healthy children controls ($0.46%{\pm}0.26%$). A significantly positive correlation was found between the frequency of Treg and the platelet count in children. Conclusion: These data suggest that a lower frequency of Treg contributes to the breakdown of self-tolerance, and may form the basis for future development of specific immunomodulatory therapies. Furthermore, Treg frequency has prognostic implication toward the natural course and long-term outcomes of childhood chronic ITP.

  • Small cell lung carcinoma (SCLC) is a cancer that shows aggressive behavior, early spread to distant sites, and frequent association with distinct paraneoplastic syndromes. Spontaneous remission of cancer, particularly of SCLC, is a rare biological event. Cases involving spontaneous regression of SCLC were reported, and were associated with paraneoplastic syndromes of the nervous system. This article reports on a 78-year-old man with SCLC in remission, with neurological symptoms. The patient visited the hospital because of generalized weakness, and imaging studies revealed a mass in the lower lobe of the left lung, pathological evaluation showed SCLC. The patient refused oncologic treatment and was treated only with conservative care. In follow-up study the diameter of the mass had decreased from initial 32 mm, 9 months after admission to 20 mm, 17 months after admission to 13 mm. The patient kept complaining of generalized weakness, dizziness, and paresthesia of limbs. We assumed that, in this case, the spontaneous remission of lung cancer was related to the immunologic response directed against the tumor, which is believed to be an important factor in the pathogenesis of paraneoplastic neurologic syndromes.

  • Acute pulmonary embolism (PE) ranges from asymptomatic to often fatal, incidentally discovered emboli to massive embolism causing immediate death. Acute PE may occur rapidly and unpredictably and may be difficult to diagnose. Mortality and complications can be reduced by prompt diagnosis and therapy. Untreated PE is associated with a mortality rate of approximately 30 percents. Most patients with PE have endogenous fibrinolysis, although it is not effective enough to prevent PE. A case of spontaneous remission of untreated acute PE has not previously been reported. Here we present a case of spontaneously resolved acute PE without any treatment.

  • Various immunotherapeutic modalities have been used based on the autoimmune pathogenic mechanisms of myasthenia gravis (MG). Cell-mediated immunity as well as auto-antibodies may play a role in the remission and relapse of MG. We recently experienced two patients with MG who showed spontaneous remission after inadvertent severe leukopenia. These findings suggest that the cell-mediated immune process is important in the treatment of MG, and selective suppression of leukocyte may induce remission in the patients with intractable MG.

  • Immune thrombocytopenia (ITP) is a disease in which thrombocytopenia occurs because of immune-mediated platelet destruction and decreased platelet production. Although many pediatric patients with ITP experience spontaneous remission or reach remission within 12 months of first-line therapy, approximately 20% progress to chronic ITP. Patients who do not respond to first-line treatment or experience frequent relapses are of great concern to physicians. This review summarizes recent treatments for second-line treatment of pediatric chronic ITP.

  • Surgical correction of patent ductus arteriosus is,under most circumstances,highly successful and carries a low mortality. But infected PDA is yet potentially dangerous due to its frequent recurrence and resistant organisms to antibiotics. And,in surgical correction,surgeon may face the possibility of tearing of ductus arteriosus arterial end due to friability and adhesion of its surrounding tissue.This report demonstrats another problem in treatment of infected patent ductus arteriosus.This thirteen years old female patient received susceptible combined antibiotics intravenously from the day of admission and remitted from 4th.week of therapy.This remission state continued for 12days without relapse.But the pulmonary artery ruptured in this remission period.In autopsy,bacteria was not found in ductal vegetation.Also,there was no pulmonary artery aneurysm,Our experience show that in infected PDA,pulmonary artery can rupture spontaneously during remission period without aneurysmal formation.

  • Focal myositis is a benign inflammatory pseudotumor of a skeletal muscle that clinically mimics a tumor of soft tissue, but the cause of which is obscure. I report here a case of multifocal recurrent nonpainful myositis found in a 68-year-old man who showed a subacute multifocal recurrent nonpainful inflammatory myopathy affecting discrete muscle groups with spontaneous remission and/or some medication.

  • 소아에서 드물게 보고되는 토로사-헌트 증후군은 둔하면서 지속적인 안와 주위의 통증과 안구운동 장애 및 해면동 주위의 뇌신경 침범을 특징으로 하는 질환으로 비특이적 염증조직에 기인한 것으로 알려져 있다. 이는 자연 치유도 가능하나 대개 스테로이드가 증상의 회복에 효과적이며 신속한 호전을 유도한다. 토로사-헌트 증후군은 그 예후가 양호하다고 알려져 있으나 일부는 치료 후에 재발하기도 한다. 우리는 토로사-헌트 증후군으로 진단받고 스테로이드 치료 후 특별한 휴우증 없이 회복되었다가 스테로이드를 감량 중 잦은 두통과 안와 주위 통증의 재발을 호소하여 장기간 저용량 스테로이드를 투여 받고 있는 여아 1례를 경험하였기에 이를 보고하는 바이다.

  • Letrozole is a drug used in the treatment of postmenopausal women with breast and ovarian tumours. There is no evidence in the literature indicating its use in treating gastric cancer. We present a 68 year old lady admitted from the emergency department with weight loss, malaise and anaemia. Investigations confirmed the presence of two different primary tumours in the left breast and the stomach. Following that this patient with oestrogen receptor positive breast cancer and oestrogen receptor negative gastric cancer was treated with letrozole for her breast cancer followed by a gastric resection. Independent histology by two pathologists pre-operatively diagnosed gastric adenocarcinoma. Post-operatively, independent analysis of the resected stomach, omentum and lymph nodes revealed no evidence of gastric cancer. Therefore we conclude that there is a possibility of letrozole having an effect on gastric cancer. Further studies are needed.

  • Clinical analysis were performed on 68 cases of subcutaneous emphysema, those were visited at the emergency center of Chosun university hospital during the period form 1992 to 1994. The following result was obtained. 1 The incidence of subcutaneous emphysema was 0.16%, and male was dominant [M:F=6.9:1 .2 The age distribution of subcutaneous emphysema was from 4 to 77 years old and mean age was 49.6$\pm$17.8 years[$\pm$SD 3 The most presenting symptoms were chest pain[49% , and the proceeding cause was traffic accident[38% . 3 The most associated disease was a ipsilateral pneumothorax[59% . 4 Conservative management is an indication in the majority of cases of subcutaneous emphysema because it is usually a self-limited condition and spontaneous remission usually occurs. We conclude that initial effort must be made to detect the underlying cause of the subcutaneous emphysema in order that appropriate management may be undertaken.
