PURPOSE: Tuberous sclerosis is an autosomal dominant multisystemic neurocutaneous syndrome characterized by the development of multiple hamartoma distributed through the body, skin, brain, heart, kidney, and lung. The classic triad is seizure, mental retardation, and facial angiofibroma. We experienced a case of a tuberous sclerosis associated with the facial lesion and multiple masses on scalp, forehead, and right lower extremity. METHODS: This a 34-year-old male patient had subependymal giant cell astrocytoma in brain and multiple angiomyolipoma in both kidneys. Tangential excision with razor blade and dermabrasion were done on the centrofacial area. We excised other lesions and the mass on scalp was excised and covered with split thickness skin graft. RESULTS: The histopathological finding revealed that the facial lesion was angiofibroma and the others were multiple fibroma. CONCLUSION: In our case of tuberous sclerosis, we chose the tangential excision to remove the large nodules of angiofibroma, and then dermabrasion was used to smooth the final contour. The patient appeared to have a good results from this treatment modality. But, tuberous sclerosis is an disease that needs long term follow-up to check up the recurrence of skin problem.

The effectiveness of below-the-knee (BTK) percutaneous transluminal angioplasty to obtain successful revascularization in patients with critical limb ischemia has been well established, and many of these patients with chronic lower-extremity disease have been treated by endovascular intervention as the firstline treatment. Dorsal-plantaer loop technique is one of the new BTK interventional techiniques, and includes recanalization of both pedal and plantar arteries and their anatomical anastomoses. This method generally needs two approaches simultaneously, including antegrade and retrograde. In this report, however, we describe a case in which dorsal-plantar loop technique with only one antegrade approach, using chronic total occlusion devices via anterior tibial artery, was used to successfully recanalize BTK arteries. We think that this new technique, which may represent a safe and feasible endovascular option to avoid more invasive, time-consuming, and riskier surgical procedures, especially in end-stage renal disease and diabetes, should be considered whenever the foot is at risk, and results of above-the-ankle percutaneous transluminal angioplasty remain unsatisfactory or insufficient to achieve limb salvage.

PURPOSE: Currently, insufficient data exist to evaluate the relationship between angiographic late loss (LL) and long-term clinical outcome after drug-eluting stent (DES) implantation. In this study, we hypothesized that angiographic LL between 0.3 and 0.6 mm correlate with favorable long-term clinical outcomes. MATERIALS AND METHODS: Patients were enrolled in the present study if they had undergone both DES implantation in single coronary vessel and a subsequent follow-up angiogram (n=634). These individuals were then subdivided into three groups based on their relative angiographic LL: group I (angiographic LL <0.3 mm, n=378), group II (angiographic LL between 0.3 and 0.6 mm, n=124), and group III (angiographic LL >0.6 mm, n=134). During a 5-year follow-up period, all subjects were tracked for critical events, defined as any cause of death or myocardial infarction, which were then compared among the three groups. RESULTS: Mean follow-up duration was 63.0+/-10.0 months. Critical events occurred in 25 subjects in group I (6.6%), 5 in group II (4.0%), and 17 in group III (12.7%), (p=0.020; group I vs. group II, p=0.293; group II vs. group III, p=0.013). In a subsequent multivariate logistic regression analysis, chronic renal failure [odds ratio (OR)=3.29, 95% confidence interval (CI): 1.48-7.31, p=0.003] and long lesion length, defined as lesion length >28 mm (OR=1.88, 95% CI: 1.02-3.46, p=0.042) were independent predictors of long-term critical events. CONCLUSION: This retrospective analysis fails to demonstrate that post-DES implantation angiographic LL between 0.3 and 0.6 mm is protective against future critical events.

PURPOSE: Data comparing the clinical benefits of medical treatment with those of percutaneous coronary intervention (PCI) in an elderly population with angina pectoris are limited. Therefore, we evaluated the efficacy of elective PCI versus optimal medical treatment (OMT) in elderly patients (between 75 and 84 years old) with angina pectoris. MATERIALS AND METHODS: One hundred seventy-seven patients with significant coronary artery stenosis were randomly assigned to either the PCI group (n=90) or the OMT group (n=87). The primary outcome was a composite of major adverse events in the 1-year follow-up period that included cardiovascular death, non-fatal myocardial infarction, coronary revascularization, and stroke. RESULTS: Major adverse events occurred in 5 patients (5.6%) of the PCI group and in 17 patents (19.5%) of the OMT group (p=0.015). There were no significant differences between the PCI group and the OMT group in cardiac death [hazard ratio (HR) for the PCI group 0.454; 95% confidence interval (CI) 0.041-5.019, p=0.520], myocardial infarction (HR 0.399; 95% CI 0.039-4.050, p=0.437), or stroke (HR 0.919; 95% CI 0.057-14.709, p=0.952). However, the PCI group showed a significant preventive effect of the composite of major adverse events (HR 0.288; 95% CI 0.106-0.785, p=0.015) and against the need for coronary revascularization (HR 0.157; 95% CI 0.035-0.703, p=0.016). CONCLUSION: Elective PCI reduced major adverse events and was found to be an effective treatment modality in elderly patients with angina pectoris and significant coronary artery stenosis, compared to OMT.

Primary stenting in femoropopliteal lesions of intermediate length has recently shown favorable outcomes. However, stent fractures are a concern after bare metal stent implantation. The incidence of stent fracture varies widely (ranging from 2% to 65%) depending on factors such as the treated lesions or stent type and may potentially lead to various complications. We reported a case of stent fracture with complete dislocation combined with recurrent in-stent reocclusion and aneurysm formation in a patient with occlusive disease of the femoropopliteal artery, which was successfully treated with self-expandable endovascular stent graft.

We investigated the incidence, predictors, and long-term clinical outcomes of new-onset diabetes mellitus (DM) after percutaneous coronary intervention (PCI) with drug-eluting stent (DES). A total of 6,048 patients treated with DES were retrospectively reviewed and divided into three groups: 1) known DM (n = 2,365; fasting glucose > 126 mg/dL, glycated hemoglobin > 6.5%, already receiving DM treatment, or previous history of DM at the time of PCI); 2) non-DM (n = 3,247; no history of DM, no laboratory findings suggestive of DM at PCI, and no occurrence of DM during follow-up); and 3) new-onset DM (n = 436; non-DM features at PCI and occurrence of DM during follow-up). Among 3,683 non-DM patients, 436 (11.8%) patients were diagnosed with new-onset DM at 3.4 ± 1.9 years after PCI. Independent predictors for new-onset DM were high-intensity statin therapy, high body mass index (BMI), and high level of fasting glucose and triglycerides. The 8-year cumulative rate of major adverse cardiac events (a composite of cardiovascular death, myocardial infarction, stent thrombosis, or any revascularization) in the new-onset DM group was 19.5%, which was similar to 20.5% in the non-DM group (P = 0.467), but lower than 25.0% in the known DM group (P = 0.003). In conclusion, the incidence of new-onset DM after PCI with DES was not low. High-intensity statin therapy, high BMI, and high level of fasting glucose and triglycerides were independent predictors for new-onset DM. Long-term clinical outcomes of patients with new-onset DM after PCI were similar to those of patients without DM.

PURPOSE: Numerous experimental studies have shown the benefits of treating thermal burns by cooling. Nevertheless, few studies have shown the clinical effect of cooling therapy on thermal burns. This study aimed to identify the clinical effect of immediate cooling therapy. METHODS: The research was conducted as a retrospective, case-control study. All patients had thermal injuries characterized as a superficial second-degree burn. In the cooling group, 14 patients had first-aid cooling therapy delivered by either parents, caregivers, general practitioners, local hospitals, and/or Myongji hospital. Included in the study were 22 control patients who were not treated with any cooling therapies. Other clinical factors, such as age, sex, cause of burn injury, and burn area (Total Body Surface Area %), were taken into consideration. The duration of treatment was defined as the time from the occurrence of the injury to the presence of complete re-epithelialization, as confirmed by two surgeons. RESULTS: The duration of treatment in the cooling group was significantly less than that the control group (p < 0.05). CONCLUSION: Cooling therapy as an initial emergent treatment is clinically effective for superficial seconddegree burn injuries.

PURPOSE: To evaluate the effect of statin treatment on strut coverage after drug-eluting stent (DES) implantation. MATERIALS AND METHODS: In this study, 60 patients were randomly assigned to undergo sirolimus-eluting stent (SES) or biolimus-eluting stent (BES) implantation, after which patients were randomly treated with pitavastatin 2 mg or pravastatin 20 mg for 6 months. The degree of strut coverage was assessed by 6-month follow-up optical coherence tomography, which was performed in 52 DES-implanted patients. RESULTS: The percentages of uncovered struts were 19.4+/-14.7% in pitavastatin-treated patients (n=25) and 19.1+/-15.2% in pravastatin-treated patients (n=27; p=0.927). A lower percentage of uncovered struts was significantly correlated with a lower follow-up low-density lipoprotein (LDL) cholesterol level (r=0.486; p=0.009) and a greater decline of the LDL cholesterol level (r=-0.456; p=0.015) in SES-implanted patients, but not in BES-implanted patients. In SES-implanted patients, the percentage of uncovered struts was significantly lower among those with LDL cholesterol levels of less than 70 mg/dL after 6 months of follow-up (p=0.025), but no significant difference in this variable according to the follow-up LDL cholesterol level was noted among BES-implanted patients (p=0.971). CONCLUSION: Lower follow-up LDL cholesterol levels, especially those less than 70 mg/dL, might have a protective effect against delayed strut coverage after DES implantation. This vascular healing effect of lower LDL cholesterol levels could differ according to the DES type.

PURPOSE: To evaluate the impact of pre-procedural coronary plaque composition assessed by virtual histology intravascular ultrasound (VH-IVUS) on late stent malapposition assessed by optical coherence tomography (OCT) following drug-eluting stent (DES) implantation. MATERIALS AND METHODS: The study population consisted of 121 patients (121 lesions) who underwent both pre-procedural VH-IVUS and follow-up OCT after DES implantation. The association between pre-procedural plaque composition [necrotic core (NC), dense calcium (DC), fibrotic (FT), and fibro-fatty (FF) volumes] assessed by VH-IVUS and late stent malapposition (percent malapposed struts) or strut coverage (percent uncovered struts) assessed by follow-up OCT was evaluated. RESULTS: Pre-procedural absolute total NC, DC, FT, and FF plaque volumes were 22.9+/-19.0, 7.9+/-9.6, 63.8+/-33.8, and 16.5+/-12.4 mm3, respectively. At 6.3+/-3.1 months post-intervention, percent malapposed and uncovered struts were 0.8+/-2.5% and 15.3+/-16.7%, respectively. Pre-procedural absolute total NC and DC plaque volumes were positively correlated with percent malapposed struts (r=0.44, p<0.001 and r=0.45, p<0.001, respectively), while pre-procedural absolute total FT plaque volume was weakly associated with percent malapposed struts (r=0.220, p=0.015). Pre-procedural absolute total DC plaque volume was the only independent predictor of late stent malapposition on multivariate analysis (beta=1.12, p=0.002). There were no significant correlations between pre-intervention plaque composition and percent uncovered struts. CONCLUSION: Pre-procedural plaque composition was associated with late stent malapposition but not strut coverage after DES implantation. Larger pre-procedural absolute total DC plaque volumes were associated with greater late stent malapposition.
