Graves disease occur in association with myasthenia gravis is rare. We report a case of Graves disease and myasthenia gravis treated by bilateral subtotal thyroidectomy and total thymectomy simultaneously. A 37 year old woman was admitted with anterior neck mass and ptosis. Various examinations were compatible with combined Graves disease and myasthenia gravis. The bilateral subtotal thyroidectomy and total thymectomy were done simultaneously. The pathologic diagnosis was Graves disease and thymic hyperplasia. The patients postoperative course was uneventful. The thyroid function of patient became euthyroid and the clinical symptoms related with myastenia gravis resolved during follow up period.

BACKGROUND AND OBJECTIVES: In acute myocardial ischemia, the conduction velocity of action potential is decreased by several electrophysiological and physical factors. The ventricular activation time(VAT) is a time duration of electrical impulse propagating from endocardium to epicardium. The goal of this study is to determine whether the reduction in conduction velocity in acute myocardial ischemia can lead a change in VAT. MATERIALS AND METHOD: Thirty patient, 18 males and 12 females, who had received percutaneous balloon coronary angioplasty(PTCA) were enrolled. The mean age was 59 years old. A twelve lead surface electrocardiogram(ECG) were obtained before, during, 1 minute, 5 minutes, and 10 minutes after the PTCA as digitized data by using Cardiolab EP 4.1 program. The magnitude of the QRS wave was amplified 3 to 4 folds and the speed was increased to 200mm/sec in order to get the VAT easily and accurately. The data was the mean of three consecutive VATs. The number of vessel treated with PTCA included left anterior descending artery(12), left circumflex artery(9), and right coronary artery(9). Among twelve chronic stable angina, sixteen unstable angina, and two acute myocardial infarction patients, twenty six had single and four had two vessel diseases. RESULTS: The significant increase in VAT during PTCA compared to that before PTCA was observed in eight of 12 leads. In addition, the significant decrease in VAT of 1, 5, and 10 minutes after PTCA compared to that during PTCA were noted. Furthermore, 10 minutes after PTCA, VAT decreased significantly compared to that before PTCA. The leads did not show a significant change of VAT depending on target vessels. The ECG of 16 patients showed changes of the ST segment during PTCA. The changes of VAT were not related to the ST segment change. CONCLUSION: The conduction delay from endocardium to epicardium in acute myocardial ischemia was presented as a prolongation of VAT in surface ECG. In addition, the conduction delay was recovered within 5 minutes after relief of ischemia. Therefore, the changes of VAT can possibly be used as one of the noninvasive parameters of myocardial ischemia.

BACKGROUND AND OBJECTIVES: Though the surgical intervention of subclavian artery stenosis has been effective, its high morbidity and mortality have limited its clinical application. In 1980 percutaneous balloon angioplasty of stenotic artery was introduced as a substitute for surgical intervention and subsequent reports have supported its efficacy noting that it is more effective when combined with stent. The purpose of this study was to assess the feasibility, safety, and efficacy of percutaneous intervention as an alternative or primary therapy for symptomatic subclavian artery stenosis. METHODS: Between September 1993 and October 1998, 17 lesions in 16 patients of symptomatic subclavian artery stenosis were enrolled as candidates for nonsurgical intervention. We performed percutaneous balloon angioplasty with stenting to the subclavian artery stenosis and evaluated the early results. RESULTS: 1)The patients had a mean age of 55+/-14 years and 13 of 16 patients were male. 2)Subclavian artery stenting was successful in 94% (16/17) of the lesion without significant complications. The cause of failure was suboptimal result after deployment of stent. 3)The types of stents deployed were Strecker stents in 4, Palmaz stents in 8, Wall stents in 3 and Jo stents in 2 cases. 4)The peak and mean pressure gradient reduced from 58.5+/-17.0 to 8.5+/-7.4 and 31.4+/-13.0 to 4.7+/-5.5 mmHg respectively (p<0.01) and the degree of luminal stenosis decreased from 92.5+/-8.5% to 10.0+/-14.3%. (p<0.01) CONCLUSION: Subclavian artery stenosis can be managed safely and effectively through percutaneous balloon angioplasty with stenting, with an excellent technical success rate and less morbidity and mortality particularly in patients coexisting other vascular and systemic diseases. However, the long-term patency and clinical effects should be warranted.

One case of malignant acanthosis nigricans associated with internal malignancy has been presented and the suhject of malignant acanthosis nigricans has been revieived. The patient who was 50 year old man had been affected generalized hyperpigmentation with pnpillomatosis especially on forehead, neck, axilla, umbilical area, anogenital area, palm and soles and associated with highly malignant adenocarcinoma of stomach. Diagnosis was confirmed by characteristic clinical appearance, explorative laparatomy and histopathologically

In order to evaluate antitumor rnechanisms of interleukin (IL)-12/IL-2 that has been shown significant tumor suppressive activity on established primary and metastatic Renca tumor, we studied chemokine gene expression induced by direct action of IL- 12/IL-2 or cytokine cascade. IL-12/IL-2 induced gene expression of interferon gamma (IFN-r) and granulocyte monocyte-colony stimulating factor (GM-CSF) in splenocytes, and it induced gene expression of monokine induced by IFN-r (Mig), interferon inducible protein 10 (IP- 10), SDF-1, macrophage inflammatory protein (MIP)-1a, MIP-1B, MIP-2, monocyte chemotactic protein (MCP)-1, and Rantes in tumor mass. However IL-12/IL-2 could not induce these chemokines in tumor mass of GKO mice and Renca cell in vitro. IL- 12 also did not increased chemokine gene expression in Renca cell in vitro, but IFN-r induced gene expression of Mig, IP-10, MCP-1 in Renca cell in vitro. In the chemotaxis assay, culture supernatant of Renca cell stimulated with IFN-r increased splenocyte migration in vitro. All these data suggest IL-12/IL-2 can induce IFN-r-chemokine cascade in tumor mass, and Mig, IP-10, MCP-1 produced from tumor cell may play an important role for initial immune cell migration into tumor mass.
