Penile Mondor disease (MD) is a palpable, painful, subcutaneous induration caused by superficial dorsal penile vein thrombosis. We report a case of penile MD that was suspected to be related to prolonged oral sildenafil use. A 46-year-old man visited our emergency department with sustained penile pain and swelling that began 7 hours after sexual intercourse. He had used oral sildenafil intermittently for 11 years and engaged in sexual intercourse the previous night after taking sildenafil. Examination revealed no evidence of intercourse-related trauma to the genital area or an increase in penile skin temperature. However, penile swelling and tenderness over the protruding dorsal penile vein were noted. A color Doppler ultrasound examination was performed immediately, which showed hyperechoic thrombosis in the right superficial dorsal penile vein that was dilated, with soft tissue swelling and no detectable flow signal in the thrombotic lesion. The patient was diagnosed as having penile MD. The patient was treated conservatively. Some reports have indicated the involvement of sildenafil in thrombogenesis. Physicians should be aware that prolonged oral sildenafil use may be associated with penile MD.

The association between hypercoagulability and malignant disease was first described by Armand Trousseau in 1865. According to Trousseau, the thrombophlebitis was usually/migratory and recurrent and involved both venous and arterial system. Thrombosis remains the hallmark of Trousseau's syndrome, although a wide variety of coagulation disorders including disseminated intravascular coagulation(DIC), pulmonary embolism, thrombotic endocarditis, and bleeding have been associated with the syndrome. Since then, abnormalities of the coagulation system have been repeatedly demonstrated in patients with cancer. Pancreatic carcinoma is thought to carry the highest risk of Trousseau's syndrome although the number of cases of Trousseau's syndrome is actually higher in patients with lung cancer because of the greater prevalence of this tumor. We report a thirty-five year old male patient with Trousseau's syndrome associated with lung cancer initially presenting deep vein thrombosis.

Antiphospholipid syndrome is a thrombotic disorder characterized by the association of arterial and venous thrombosis with the antibodies directed toward phospholipids. The presence of these antibodies in systemic lupus erythematosus(SLE) has been shown to be related to several clinical and analytical alterations. We experienced one case of lupus nephritis with positive antiphospholipid antibodies in a 10-year-old girl whose chief complaint was persistent microscopic hematuria. We report this case with a brief review of related literatures. (J. Korean Soc Pediatr Nephrol 2001 ;5 : 219-24)

Acute limb ischemia (ALI) due to an embolism is associated with high mortality rate and poor prognosis, and early diagnosis with prompt revascularization is required to reduce the risk of limb amputation or even death. The etiologies of ALI are diverse, and it includes an embolism from the heart and thrombotic occlusion of the atherosclerotic native vessels, stents, or grafts. An uncommon cause of ALI is acute arterial thromboembolism, and atrial fibrillation (AF) is the single most important risk factors for systemic thromboembolism. It is important to correctly identify the source of ALI for secondary prevention, as it depends on the underlying cause. Percutaneous transluminal angioplasty (PTA) has been proven to be a safe and effective treatment for focal atherosclerotic and thrombotic occlusive diseases of the aorta and its major extremity branches. Herein, we report on a 77-year-old female patient with acute upper limb ischemia, treated by PTA using a catheter-guided thrombectomy. He was newly diagnosed with paroxysmal AF (PAF) while evaluation the cause of his acute arterial thromboembolism. We recommend that cardiologists always consider PAF as a possible diagnosis even in patients without any history of AF under ALI because it is possible to develop thromboembolism in clinical practice.

Coronary artery ectasia (CAE) is defined as the dilation of a segment of a coronary vessel to at least 1.5 times the diameter of its normal adjacent segment. Mean platelet volume (MPV) plays a role in acute coronary syndromes, with high MPV correlating to poor prognosis for acute thrombotic events and CAE. Several studies investigated the relationship between MPV and CAE, resulting in conflicting results. These results led us to systematically review all studies investigating the relationship between MPV and ectatic heart diseases by performing a meta-analysis study in order to report a unified result. This meta-analysis study investigated all case-control articles examining the relationship between MPV and CAE. All studies in the following databases published until January 31, 2018, were investigated: Science Direct, Scopus, PubMed, Google Scholar, and Web of Science. Following a quality control evaluation, 14 articles, all of which were published following studies performed in Turkey from 2007 to 2016, met the criteria for study inclusion. After pooling the results from all of the articles, a total standardized mean difference (SMD) value of 0.584 (95% CI, 0.219, 0.95) was obtained using the D+L pooled SMD, indicating a significant difference (P=0.002) between the two groups, with higher MPV values in ectatic patients when comparing to healthy individuals. Therefore, increased MPV levels were significantly related to CAE, suggesting that platelets, with their inflammatory and thrombotic activities, play a role in this disease. Therefore, anti-platelet and anti-inflammatory therapies may be effective in treating CAE.

The purpose of this study was to investigate the effects of Anti-Thrombotic Activities and Cardiovascular Improvement of Fermented Garlic Extracts. The incidence of cardiovascular diseases (CVDs) is increasing rapidly in developed countries, with CVDs now representing the leading cause of morbidity and mortality. Natural products and ethnomedicines have been shown to reduce the risk of CVDs. Garlic is a medicinal plant used throughout the world for its anti-inflammatory, antioxidant, and antiplatelet activities. We hypothesized that fermented preparations of these products may possess stronger antiplatelet effects than the non-fermented forms owing to the increased bioavailability of the bioactive compounds produced during fermentation. Therefore, we compared these compounds via in vitro and ex vivo platelet aggregation assays by using standard light transmission aggregometry and ex vivo granule secretions from rat platelets. We found that fermented preparations exerted more potent and significant inhibition of platelet aggregation both in vitro and ex vivo. Likewise, ATP release from dense granules of platelets was also significantly inhibited in fermented preparation-treated rat platelets compared to that in non-fermented preparation-treated ones. We concluded that fermented preparations exerted more potent effects on platelet function both in vitro and ex vivo, possibly as a result of the increased bioavailability of active compounds produced during fermentation. We therefore suggest that fermented products may be potent therapeutics against platelet-related CVDs and can be used as antiplatelet and antithrombotic agents.

The long-term clinical issues in Kawasaki disease are concerned with the coronary artery lesions that result in aneurysmal formation, thrombotic occlusion, progression to ischemic heart disease, and premature atherosclerosis. We here report a 3 month old infant with Kawasaki disease complicated by giant coronary aneurysm with thrombosis. After urokinase(10,000 IU/kg) and heparin(400 IU/kg) were injected for two days as thrombolytic agents, thrombi were successfully dissolved. Even though long-term oral anticoagulation with low-dose aspirin, dipyridamole and coumadin were administered, thrombosis of the left main coronary artery was slowly increased. five years later, coronary angiography showed nearly total occlusion of the left anterior descending artery and collaterals from the right posterior branch and radionuclide scan demonstrated complete reversible perfusion defect of several portions of the left ventricle.

True aneurysm of the brachial artery is a rare disease entity. The mechanism of aneurysm formation is considered to be compression of the arterial wall, producing contusion of the media and subsequent weakness of the wall and fusiform dilatation. It can be caused by arteriosclerotic, congenital, and metabolic disorders, and can be associated with diseases such as Kawasaki's disease. Doppler ultrasonography, computed tomography, arteriography, and selective upper extremity angiography may be performed for establishing the diagnosis of aneurysm. The best therapeutic option is operative repair, and it should be performed without any delay, in order to prevent upper extremity ischemic or thrombotic sequelae. Here, we report a case of recurrent brachial artery aneurysm with review of the literature.

MELAS is the condition associated with mutant mtDNA that most closely mimics thrombotic cerebrovascular disease. Characteristic abnormalities are two. first, 'ragged-red fibers' in muscle biopsy. second, point mutation in the mitochondrial DNA analyses. The characteristic clinical presentations of MELAS are short stature, recurrent stroke like episodes, migraine-like headache, sensorineural hearng loss, glucose intolerance and neuropathy. We now report a case of MELAS syndrome having mitochondrial DNA mutation with an A to G transition at the 3,243rd position diagnosed in Chung-ang Hospital.

The Panax ginseng Mayer is used in conventional medicine in Asia owing to its preventing effects on thrombosis, hypertension, atherosclerosis, vasorelaxation and myocardial infarction. Because platelets are crucial mediators of cardiovascular diseases, many studies have investigated its functions. The previous study showed the antiplatelet effects of crude ginseng fraction and two of its components, ginsenoside Rg3 (20S and 20R). In addition, ginsenoside Rg3-enriched fraction shows an inhibitory effect on collagen-activated rat platelets. However, the mechanism underlying this effect remains unclear. Thus, I investigated the inhibitory action of ginsenoside Rg3 (20S, G-Rg3) on the regulation of signaling molecules involved in ${\alpha}IIb/{\beta}_3$ activation. I found that G-Rg3, in a cyclic AMP dependent manner, inhibited thrombin-induced activation of human platelets and affinity of fibrinogen and fibronectin with ${\alpha}IIb/{\beta}_3$. Thus, in the present study, G-Rg3 showed an inhibitory effect on glycoprotein IIb/IIIa (${\alpha}IIb/{\beta}_3$) activation, suggesting its potential use for preventing platelet-mediated thrombotic disease.
