“…Although a previous ecological study predicted future mortality due to asbestos slate roofs, particularly MM (8), the study focused on asbestos consumption in general, and not on slate roof exposure. Another study found that some of the indoor air concentrations of asbestos in slate roof houses in Busan city exceeded 1.0E-04 f/mL [22]; although this might not support a high incidence of PD in in slate roof-dense areas, it might support the development of LC. According to the US Environmental Protection Agency, air concentrations at specified risk levels of combined LC and MM which cause extra cancer are 1 in 10,000 of 4E-4 f/mL 1 in 100,000 of 4E-5 f/mL and 1 in 1,000,000 of 4E-6 f/m L [23].…”

This study aimed to evaluate the relationship between various asbestos exposure routes and asbestos-related disorders (ARDs). The study population comprised 11,186 residents of a metropolitan city who lived near asbestos factories, shipyards, or in slate roof-dense areas. ARDs were defined from chest X-rays indicating lower lung fibrosis (LFF), pleural disease (PD), and lung masses (LMs). Of the subjects, 11.2%, 10.4%, 67.2% and 8.3% were exposed to asbestos via occupational, household, neighborhood, and slate roof routes, respectively. Regarding adjusted confounders and other exposure routes, the odds ratio (OR) of PD from household exposure (i.e., living with asbestos-producing workers) was 1.9 (95% confidence interval: 0.9–4.2), and that of LLF and PD from neighborhood exposure, or residing near asbestos factories) for <19 or >20 years, or near a mine, were 4.1 (2.8–5.8) and 4.8 (3.4–6.7), 8.3 (5.5–12.3) and 8.0 (5.5–11.6), and 4.8 (2.7–8.5) and 9.0 (5.6–14.4), respectively. The ORs of LLF, PD, and LM among those residing in slate-dense areas were 5.5 (3.3–9.0), 8.8 (5.6–13.8), and 20.5 (10.4–40.4), respectively. Substantial proportions of citizens residing in industrialized city have potentially been exposed to asbestos, and various exposure routes are associated with the development of ARDs. Notably, this may be the first finding of the health effects of slate roof exposure. However, given the limitations of this study, including potential confounders such as socioeconomic status, further research is needed.

“…Percutaneous transluminal coronary angioplasty (PTCA) is now an established treatment for patients with coronary artery disease since first introduced by Andreas Gruentzig in 1977. Though improvements in techniques and devices permit a high primary success rate, acute or threatened closure and frequent restenosis of the dilated segments are major obstacles to expanding its usefulness and limit the long-term benefit in patients who underwent successful coronary angioplasty 1 – 4 ) .…”

ObjectivesInitial and late results after implantation of Freedom stents, a balloon expandable stainless steel coil stents were evaluated.MethodsFrom Jun. 1996 to Nov. 1997, we implanted 123 Freedom stents in 122 lesions in 117 patients and performed follow-up coronary angiograms at 7.0 ± 3.6 months after stents placement. Clinical courses after stenting and follow-up coronary angiographic findings were evaluated. Comparison of clinical, angiographic, and procedural factors according to the presence or absence of restenosis was performed.ResultsIn 117 patients who underwent stents implantation, major complications were not observed. Follow-up coronary angiograms were performed in 47 stents in 41 patients (35%). Among 47 stents, angiographic significant restenosis (percent diameter stenosis > 50%) was observed in 13 (28%). Mean age in 41 patients was 59 ± 9 years, with 27 male patients (66%). Indications for stents implantation were de novo lesions in 18 (38%), suboptimal results after PTCA in 18 (38%), bail-out lesions in 4 (9%) and restenotic lesions in 7 (15%). Lesion types by AHA/ACC classification were A in 1 (1%), B1 in 10 (21%), B2 in 17 (36%), and C in 19 (40%). Average lesion length was 13.7 ± 9.0mm, stent diameter 3.0 ± 0.3mm, and stent length 24.6 ± 9.0 mm. There were no significant differences of the clinical, angiographic, and procedural characteristics according to the presence or absence of restenosis.ConclusionFreedom coronary stents implantation is safely performed in various morphology of coronary lesions and no significant predictive factors on restenosis in follow-up coronary angiogram were observed.

With the introduction of high pressure balloon inflations and antiplatelet therapy, the incidence of stent thrombosis has been markedly reduced, but the incidence of late stent restenosis has not. A new strategy may be local drug delivery, which maintains sustained local concentration and limits systemic complications. To evaluate the efficacy of local nitric oxide (NO) donor delivery on stent thrombosis and complications, local NO donor delivery was performed in stented patients. NO donor (2.0‐mg molsidomine) was delivered (1.0 mL/min > 10 min) using the Dispatch Catheter after predilation of target lesions in 13 patients (6 angina, 7 myocardial infarction, age 53.1 ± 11.4 years). After local NO donor delivery, Palmaz‐Schutz stents were placed using standard methods. Follow‐up coronary angiograms were performed 48 hours and 6 months after stenting. None of the patients had hypotensive effects, ischemic symptoms, or ECG changes during and after local NO donor delivery. APTT and CK values were unchanged at 3 and 24 hours after local NO donor delivery and stenting. Follow‐up coronary angiograms at 48 hours and 6 months showed all stents patent with TIMI III flow and without intrastent thrombus. No target lesion revascularization and 100% event‐free survival were observed during the 6‐month clinical follow‐up period. Intracoronary stenting may be performed safely and effectively by local NO donor delivery prior to stent implantation.
