Livedo vasculopathy clinically shows purpuric papules and recurrent ulcers in the lower extremities, mainly on the ankles, leaving characteristic scars called atrophie blanche after the healing of the ulcers. In Korean literture, about 10 cases of this disease have been reported but nothing in korean oriental medicine. So, we report a case of livedo vasculopathy in a 46 year-old female patient treated by oriental medicine therapy.

Purpose: The purpose of this study is to confirm the effect of antiplatelet drugs in diabetic peripheral vasculopathy in diabetic foot patients. Materials and Methods: We designed a retrospective study in diabetic foot patients with diabetic peripheral vasculopathy. From October 2007 to December 2013, 278 cases in 139 patients who took antiplatelet drugs over at least a six-month period were included in this study. We categorized these patients according to the type of drug used. The efficacy of antiplatelet drugs was evaluated using anklebrachial index (ABI) and pulse wave velocity (PWV). Results: Only the aspirin group showed a statistically significant increase of ABI after antiplatelet therapy ($1.10{\pm}0.12$ to $1.12{\pm}0.11$). In addition, only the cilostazol group showed a statistically significant decrease of PWV after antiplatelet therapy ($1,701.20{\pm}396.56$ to $1,627.42{\pm}324.98$). Conclusion: Aspirin and cilostazol may be used in treatment of diabetic peripheral vasculopathy, whereas dual antiplatelet therapy with aspirin and clopidogrel has no specific benefits in diabetic peripheral vasculopathy.

Since the initial International Society of Heart Lung Transplantation registry was published in 1982, the number of pediatric heart transplantations has increased markedly, reaching a steady state of 500-550 transplantation annually and occupying up to 10% of total heart transplantations. Heart transplantation is considered an established therapeutic option for patients with end-stage heart disease. The long-term outcomes of pediatric heart transplantations were comparable to those of adults. Issues affecting long-term outcomes include acute cellular rejection, antibody-mediated rejection, cardiac allograft vasculopathy, infection, prolonged renal dysfunction, and malignancies such as posttransplant lymphoproliferative disorder. This article focuses on medical issues before pediatric heart transplantation, according to the Korean Network of Organ Sharing registry and as well as major problems such as graft rejection and cardiac allograft vasculopathy. To reduce graft failure rate and improve long-term outcomes, meticulous monitoring for rejection and medication compliance are also important, especially in adolescents.

Cardiac allograft vasculopathy (CAV) is a major factor that limits the long-term survival after cardiac transplantation. Because the main feature of CAV is a diffuse stenosis that predominantly develops in the distal arteries, reperfusion therapy has shown poor outcomes. The results of cardiac retransplantation for CAV are better than that for acute resection and the survival is identical to that of patients who undergo primary transplantation. We describe a case of performing cardiac retransplantation in a 28 year-old male patient with refractory CAV and who underwent primary transplantation due to dilated cardiomyopathy 8 years previously.

Ischemic stroke caused by the cerebral vasculopathy is a rare complication of polyneuropathy, organomegaly, endocrinopathy, monoclonal gammopathy, and skin changes (POEMS) syndrome. We present a case of recurrent ischemic strokes caused by cerebral vasculopathy in a patient with POEMS syndrome. A 34-year-old man presented with gait disturbance and dizziness. Brain magnetic resonance imaging demonstrated acute ischemic stroke in the middle cerebral artery-anterior cerebral artery (MCA-ACA) border zones of bilateral hemispheres. Repeated angiographic studies showed progressive worsening of the left distal internal carotid artery, ACA, and MCA stenoses, along with sustained steno-occlusion of right MCA.

Background: Type 2 diabetic mellitus (T2DM) is an emerging global pandemic which is associated with lots of co-morbidities and reported vascular dysfunctions. T2DM associated vascular dysfunctions leads to vasculopathy in the form of altered peripheral vascular dynamics. Cold stress test (CST) is a reliable sympathetic reactivity test used for assessing vascular dysfunctions. In this study we are trying to quantify vascular dysfunctions in T2DM patients non invasively by various parameters of photoplethysmography (PPG) of cold stress test. Methods: Case control study had done in referral health center AIIMS, Raipur. Parameters are recorded by finger-PPG before, during and after CST (1 min) in 2 groups, control (n = 20 healthy volunteers) and case (n = 20 diagnosed T2DM patients). Results: Due to cold stress, PPG parameter peak amplitude was significantly decreased in both healthy and T2DM groups (p <0.001 and p <0.001, respectively). However, recovery trend of amplitude was significantly slow in T2DM compared to healthy subjects. Another PPG parameter peak to peak interval was significantly higher in healthy group compared to T2DM patients. Conclusions: This study showed that T2DM patients has significant deranged pulse volume parameters like amplitude and peak to peak interval can be used to objectively quantify the vasculopathy in T2DM patients by using sympathetic reactivity to cold stress.

The two distinctive clinical features of varicella-zoster virus (VZV) are varicella (chickenpox) by primary infection and zoster (singles) by the reactivation of latent infection. In addition to the two typical clinical symptoms mentioned above, diverse clinical manifestations have been reported as a result of VZV reactivation, including chronic radicular pain without rash, visual loss, facial palsy, dysphagia, sore throat, odynophagia, otalgia, hearing loss, dizziness, headache, hemiplegia, etc. Most of these symptoms are derived from neuropathy and vasculopathy of affected nerves and arteries. Diagnosis of VZV disease can be difficult if there is no appearance of a skin rash during development of atypical symptoms. In addition to natural infection, vaccination and anti-viral agent treatment have influenced the changes of epidemics and clinical presentations of varicella and zoster. In this article, diverse clinical manifestations caused by VZV reactivation, particular without skin rash, are reviewed.

A 31-year-old man presented with dull headache and memory disturbance lasting for one week. Computed tomographic scans revealed acute hydrocephalus. The cerebrospinal fluid contained 53 leukocytes/$mm^3$, with a mononuclear preponderance and no erythrocytes. Magnetic resonance imaging revealed hydrocephalus and leptomeningeal enhancement. Magnetic resonance angiography and digital subtraction angiography showed supraclinoid occlusion of the right internal carotid artery, which resembled unilateral moyamoya disease. Neuroendoscopic biopsy of a lesion in the septum pellucidum revealed noncaseating granulomas, which was consistent with sarcoidosis. The patient was successfully managed with intravenous methylprednisolone and ventriculoperitoneal shunting. To our knowledge, this is the first case of moyamoya-like vasculopathy associated with neurosarcoidosis.

A 14-year-old neutered-male Shih-Tzu was referred for glaucoma and hyphema accompanied by systemic hypertension. After topical corticosteroid and antiglaucoma medications, the left eye (OS) progressed phthisically, but ocular hypertension redevelop one-year-and-seven-months later. Suspected limbal melanoma developed in peripheral cornea/limbal sclera with heavily pigmented cornea OS. Ultrasound biomicroscopy and ocular ultrasonography differentiated ciliary body origin-heterogeneous mass from limbal mass. Persistent hyphema and pigmented cornea might obscure intraocular lesion and advanced diagnostic methods played a crucial role. Unlike the generally benign limbal melanoma, aggressive treatment was recommended for uveal tumor. Histopathology of enucleated OS confirmed malignant uveal melanoma with chronic hypertensive vasculopathy.

Recently, combination of surgery and radiation therapy (RT) has been recommended in the treatment of craniopharyngioma. RT could be associated with late complications, including vasculopathy. We report two cases of the moyamoya syndrome seen in children with craniopharyngioma who received RT after surgical resection. Thirty-five patients in pediatric age with craniopharyngioma were surgically treated. Fifteen out of 35 patients underwent surgical resection followed by RT or gamma knife surgery. Two of the 15 were found to have symptoms of transient ischemic attack and were diagnosed as moyamoya syndrome through the cerebral angiography. Age at RT was 4 and 13 years, respectively. The latent period for development of the moyamoya syndrome was 27 months and 3 years, respectively, after RT. The RT dose of both patients was 54 Gy. These two patients received bilateral encephaloduroarteriosynangiosis procedures. We report here these two cases of radiation-induced moyamoya syndrome in pediatric craniopharyngioma. Pediatric patients with craniopharyngioma who received RT should be reminded, during follow-up, about the risk of development of the moyamoya syndrome.
