ABSTRACT

Background@#Ultraviolet radiation causes skin damage due to increased production of reactive oxygen species (ROS) and inflammatory intermediates and direct attack of DNA of skin cells. Astaxanthin is a reddish pigment that belongs to a group of chemicals called carotenoids and has protective effects as an antioxidant. @*Objective@#To determine the beneficial effects of astaxanthin on damaged human skin after exposure to ultraviolet radiation. @*Methods@#Normal human epidermal keratinocytes (NHEKs) were pre-treated with astaxanthin for 24 hours and exposed to ultraviolet B (UVB) irradiation. After 24 hours, the Cell Counting Kit-8 (CCK-8) assay measured cell viability, ROS assay and flow cytometry analysis assessed apoptosis, and western blotting was performed to determine expression of apoptosis-related proteins. @*Results@#Astaxanthin significantly inhibited UVB-induced NHEKs cytotoxicity. Pretreatment of NHEKs with astaxanthin reduced UVB-induced ROS production. Astaxanthin caused significant inhibition of UVB-induced apoptosis, as evidenced by flow cytometry analysis and western blotting. @*Conclusion@#These results suggest that astaxanthine has a beneficial effect of reducing damage caused by UVB by effectively inhibiting cell death and reducing ROS production in keratinocytes.

ABSTRACT

Background and Objectives@#The EPIC™ stent is a self-expanding, nitinol stent that has been designed to enhance flexibility and provide expansion within vessels. The aim of the present study was to investigate the clinical efficacy and safety of the EPIC™ stent when used to treat iliac artery diseases in a prospective Korean multicenter registry. @*Methods@#A total of 138 patients with iliac artery diseases who received endovascular treatment with EPIC™ stents at 9 Korean sites were enrolled in a prospective cohort and followed for 1 year. The primary endpoint was the 1-year freedom from target lesion revascularization (TLR). The secondary endpoints were 1-year clinical patency and freedom from major adverse events (MAEs). @*Results@#The mean age of the study subjects was 66.8±8.5 years and most subjects were male (86.2%). The most frequent lesion type was Trans-Atlantic Inter-Society Consensus B (43.5%) and the majority (56.5%) of the target lesions were located in the common iliac artery. Procedural success was obtained in 99.3% of patients. The freedom from TLR and the clinical patency at 1-year follow-up were 94.9% and 92.3%, respectively. The 1-year rate of MAEs was 5.1%. Combined coronary artery disease (hazard ratio [HR], 5.91; 95% confidence interval [CI], 1.13–30.89; p=0.035) and smaller stent diameter (HR, 0.38; 95% CI, 0.17–0.88;p=0.023) were identified as independent risk factors of TLR after EPIC™ stent implantation. @*Conclusions@#The EPIC™ stents demonstrated excellent immediate and 1-year efficacy and safety outcomes in iliac artery lesions in this multicenter, prospective, registry-based study.

ABSTRACT

Anastomotic complications occur after 5% to 20% of operations for rectosigmoid colon cancer. The intestinal perfusion status at the anastomotic site is an important modifiable risk factor, and surgeons should carefully evaluate and optimize the perfusion at the intended site of anastomosis. Indocyanine green (ICG) angiography is a simple noninvasive perfusion assessment modality. The use of ICG angiography is rapidly spreading in the field of colorectal surgery. However, there is debate on its contribution to reducing anastomotic complications. In this review, we discuss the clinical utility and the standardization of ICG angiography. ICG angiography can unequivocally reveal unfavorable perfusion zones and provide quantitative parameters to predict the risk of hypoperfusion-related anastomotic complications. Many studies have demonstrated the clinical utility of ICG angiography for reducing anastomotic complications. Recently, two multicenter randomized clinical trials reported that ICG angiography did not significantly reduce the incidence of anastomotic leakage. Most previous studies have been small-scale single-center studies, and there is no standardized ICG angiography protocol to date.Additionally, ICG angiography evaluations have mostly relied on surgeons’ subjective judgment. For these reasons, it is necessary to establish a standardized ICG angiography protocol and develop a quantitative analysis protocol for the objective assessment. In conclusion, ICG angiography could be useful for detecting poorly perfused colorectal segments to prevent anastomotic leakage after colorectal surgery. An optimized and standardized ICG angiography protocol should be established to improve the reliability of perfusion assessments. In the future, artificial intelligence-based quantitative analyses could be used to easily assess colonic perfusion status.

ABSTRACT

Background@#Hot springs have been traditionally used as an alternative treatment for a wide range of diseases, including rheumatoid arthritis, bronchial asthma, diabetes, hypertension, psoriasis and atopic dermatitis. However, the clinical effects and therapeutic mechanisms associated with hot springs remain poorly defined. @*Objective@#The purpose of this study was to demonstrate the different effects of hot springs on cellular viability and secretion of inflammatory cytokines on keratinocyte in two geographically representative types of hot springs: NaHCO3 -type and NaCl-type, which are the most common types in South Korea. @*Methods@#We performed WST-1, BrdU measurements, human inflammatory cytokine arrays and enzyme-linked immunosorbent assay in HaCaT cells stimulated with toll-like receptor 3 by polyinosinic-polycytidylic acid. @*Results@#The interaction effects of cell viability and cell proliferation were not significantly different regardless of polyinosinic-polycytidylic acid stimulation and cultured hot springs type. Cytokine array and enzyme-linked immunosorbent assay analysis showed increased expression of inflammatory cytokines such as interleukin-6 and granulocyte-macrophage colony-stimulating factor by polyinosinic-polycytidylic acid stimulation, with expression levels differing according to hot springs hydrochemical composition. Cytokine reduction was not significant. @*Conclusion@#The effects and mechanisms of hot springs treatment in keratinocytes were partially elucidated.

ABSTRACT

Incontinentia pigmenti (IP), also known as Bloch-Sulzberger syndrome, is a rare X-linked dominant disorder that is generally lethal to males and almost always leads to death in utero. This disorder is a genodermatosis with characteristic cutaneous lesions and manifestations affecting the eyes, teeth, hair, and central nervous system. Genodermatosis is a hereditary disease caused by mutations in the nuclear factor-kappa B essential modulator gene mapped to chromosome Xq28. This gene encodes a variety of cytokines and chemokine regulators and is indispensable for protecting cells from tumor necrosis factor-induced apoptosis. Here we describe a case of male newborn with vesiculobullous cutaneous lesions over the left thigh and leg. We first considered the cutaneous lesions a skin infection, as they improved with intravenous antibiotics. However, recurrence and the need for repeated hospitali zations made us consider the differential diagnosis of IP, for which we performed a skin biopsy and chromosome analysis. The histology results were compatible with IP, that is, eosinophilic infiltration in the dermis and epidermis, and individual cell dyskeratinization. The chromosome analysis result was a normal 46, XY karyotype.Here we report the case of a male newborn with IP that manifested as multiple vesiculobullous skin lesions and was initially misdiagnosed as a recurrent skin infection.

ABSTRACT

Dysphagia aortica is a rare condition defined by difficulty in swallowing and is caused by extrinsic compression of the esophagus due to an ectatic, tortuous, or aneurysmatic atherosclerotic thoracic aorta. It is easy to miss the diagnosis if the clinician does not consider the possibility of dysphagia caused by a thoracic aortic aneurysm. We present the case of an 82-year-old man who developed dysphagia aortica associated with a large thoracic aortic aneurysm. Extrinsic compression of the esophagus caused by an enlarged thoracic aorta was seen on upper gastrointestinal endoscopy, barium esophagogram, and chest computed tomography. With dietary modifications, his symptoms of dysphagia gradually improved.

ABSTRACT

BACKGROUND: Several studies have suggested that proton pump inhibitor (PPI) use is associated with adverse renal outcomes, but obvious evidence for this association is lacking. We investigated the association between PPI use and adverse renal outcomes in patients who had undergone percutaneous coronary intervention. METHODS: Of the 1,284 patients hospitalized for percutaneous coronary intervention between January 2007 and May 2012, 934 patients with baseline estimated glomerular filtration rate greater than 60 mL/min/1.73 m2 were enrolled. Multivariable Cox models were used to examine whether PPI use was associated with acute and chronic adverse renal outcomes. RESULTS: In adjusted time-dependent Cox models, PPI use was associated with acute kidney injury (hazard ratio [HR], 1.46; 95% confidence interval [95% CI], 1.05–2.02), especially in patients aged 65 years or younger (HR, 2.08; 95% CI, 1.09 3.96) or in patients with diabetes (HR, 2.00; 95% CI, 1.23–3.25). In multivariable Cox models, the association between duration of PPI use and chronic kidney disease development was not statistically significant (HR of heavy users, 1.50; 95% CI, 0.61–3.67), but a longer duration of PPI use was associated with mild renal progression in patients younger than 65 years (HR of heavy users, 2.24; 95% CI, 1.09–4.60). CONCLUSION: Our results suggest that PPI use increases the risk of AKI development, and that PPI use is more significantly associated with acute and chronic renal injuries in younger patients.

ABSTRACT

OBJECTIVE: We aimed to identify depressive symptom profiles that indicated the presence of depressive disorder and present optimal cut-off sub-scores for depressive symptom profiles for detecting depressive disorder in elderly subjects with chronic physical diseases including diabetes, chronic obstructive pulmonary disease/asthma, and coronary artery disease, using the Patient Health Questionnaire-9 (PHQ-9). METHODS: Two hundred and thirty-one elderly patients with chronic physical diseases were recruited consecutively from a university-affiliated general hospital in South Korea. RESULTS: Greater severities of all 9 depressive symptoms in the PHQ-9 were presented in those with depressive disorder rather than those without depressive disorder. A binary logistic regression modeling presented that little interest [adjusted odds ratio (aOR)=4.648, p<0.001], reduced/increased sleep (aOR=3.269, p<0.001), psychomotor retardation/agitation (aOR=2.243, p=0.004), and concentration problem (aOR=16.116, p<0.001) were independently associated with increased likelihood of having depressive disorder. Receiver operating characteristics (ROC) curve analysis presented that the optimal cut-off value of score on the items for little interest, reduced/increased sleep, psychomotor retardation/agitation and concentration problem (PHQ-9) for detecting depressive disorder was 4 with 61.9% of sensitivity and 91.5% of specificity [area under curve (AUC)=0.937, p<0.001]. CONCLUSION: Our findings suggested that the diagnostic weighting of little interest, reduced/increased sleep, psychomotor retardation/agitation, and concentration problem is needed to detect depressive disorder among the elderly patients with chronic physical diseases.

ABSTRACT

PURPOSE: Calcium channel blockers diltiazem and nitrate have been used as selective coronary vasodilators for patients with significant coronary artery spasm (CAS). However, no study has compared the efficacy of diltiazem alone versus diltiazem with nitrate for long-term clinical outcomes in patients with CAS. MATERIALS AND METHODS: A total of 2741 consecutive patients without significant coronary artery disease with positive CAS by acetylcholine (Ach) provocation test between November 2004 and May 2014 were enrolled. Significant CAS was defined as a narrowing of >70% by incremental intracoronary injection of 20, 50, and 100 µg of Ach into the left coronary artery. Patients were assigned to either the diltiazem group (n=842) or the dual group (diltiazem with nitrate, n=1899) at physician discretion. To adjust for potential confounders, a propensity score matching (PSM) analysis was performed using the logistic regression model. After PSM analysis, two well-balanced groups (811 pairs, n=1622, C-statistic=0.708) were generated. RESULTS: At 5 years, there were similar incidences in primary endpoints, including mortality, myocardial infarction, revascularization, and recurrent angina requiring repeat coronary angiography between the two groups. Diltiazem alone was not an independent predictor for major adverse cardiovascular events or recurrent angina requiring repeat coronary angiography. CONCLUSION: Despite the expected improvement of endothelial function and the relief of CAS, the combination of diltiazem and nitrate treatment was not superior to diltiazem alone in reducing mortality and cardiovascular events up to 5 years in patients with significant CAS.

ABSTRACT

A 36-year-old male presented with progressive exertional dyspnea over months. Physical examination showed jugular venous distension, lung crecipitations, femoral bruit and pitting pedal edema. Echocardiogram showed a dilated right ventricle with severe pulmonary hypertension and a non collapsing inferior vena cava (IVC). On right heart catheterization, IVC oxygen saturation was noted at 92% suggesting arterial mixing; a computed tomography of the abdomen showed a fistula between the right common iliac artery to the right common iliac vein at L4 level and a massive IVC; this was linked to trauma from a disectomy done 16 years ago at L4–L5 level. Endovascular sealing with a 16 × 60 mm bifurcated stent graft (S & G Biotech, Seoul, Korea) was performed which led to complete resolution of the patient’s dyspnea. Iatrogenic vascular injury during lumbar disc surgery, although rare, can lead to high output cardiac failure developing over months to years.

ABSTRACT

BACKGROUND AND OBJECTIVES: Cigarette smoking is a risk significant factor in coronary artery disease (CAD) and vasospastic angina (VSA). However, it is largely unknown whether smoking adds to any long-term clinical risk in VSA patients. SUBJECTS AND METHODS: A total of 2797 patients without significant CAD underwent acetylcholine (Ach) provocation test between November 2004 and October 2010. Patients were divided into three groups, based on the presence of coronary artery spasm (CAS) and smoking habits (non-CAS group: n=1188, non-smoking CAS group: n=1214, smoking CAS group: n=395). All CAS patients were prescribed with anti-anginal medications for at least 6 months. The incidence of major clinical outcomes and recurrent angina of these groups were compared up to 3 years. RESULTS: There were considerable differences in the baseline clinical and angiographic characteristics among the three groups, but there was no difference in the endpoints among the three groups (including individual and composite hard endpoints) such as death, myocardial infarction, de novo percutaneous coronary intervention, cerebrovascular accident, and major adverse cardiac events. However, there was a higher incidence of recurrent angina in both the non-smoking CAS group and smoking CAS group, as compared to the non-CAS group. In multivariable adjusted Cox-proportional hazards regression analysis, smoking CAS group exhibited a higher incidence of recurrent angina compared with the non-CAS group (hazard ratio [HR]; 2.46, 95% confidence interval [CI]; 1.46-4.14, p=0.001) and non-smoking CAS group (HR; 1.76, 95% CI; 1.08-2.87, p=0.021). CONCLUSION: Cigarette smoking CAS group exhibited higher incidence of recurrent angina during the 3-year clinical follow-up compared with both the non-CAS group and non-smoking CAS group. Quitting of smoking, paired with intensive medical therapy and close clinical follow-up, can help to prevent recurrent angina.

ABSTRACT

In thromboangiitis obliterans (Buerger's disease), little progress has been made in its treatment. Medical treatment is ineffective and bypass surgery is possible only in limited case. Nowadays, endovascular intervention is popular treatment option for Buerger's disease. Endovascular procedure is safe, technically feasible, and effective. Especially, in long occlusion lesion with distal channel, endovascular intervention can be an effective treatment option. Herein, we report a case of complete wound healing following the successful endovascular intervention in Buerger's disease patient with distal channel.

ABSTRACT

OBJECTIVES: Depression is commonly comorbid in elderly patients with physical illness. This study examined the prevalence of depression in the elderly with Diabetes Mellitus (DM). METHODS: Eighty-nine patients, over 60 years old, with DM were enrolled. The medical and psychiatric history, Hamilton Rating Scale for Depression (HDRS), Patient Health Questionnaire-9 (PHQ-9), Geriatric Depression Scale-Short form Korean (GDS-SF-K), and Mini-Mental Status Examination Korean version were examined. RESULTS: The prevalence of depression was estimated as 21.3% (male 4.5% ; female 16.9%) in HDRS, 32.6% (male 9.0% ; female 23.6%) in PHQ-9, and 24.7% (male 5.6% ; female 19.1%) in GDS-SF-K. CONCLUSION: The self-reporting scale, such as GDS-SF-K, PHQ-9 is an effective screening test for depression. The prevalence of elderly depression with DM ranged from 20% to 30%, the prevalence of depression is almost three times more common in women.

ABSTRACT

Our study aimed to examine the knowledge and attitude of nursing personnel toward depression in general hospitals of Korea. A total of 851 nursing personnel enrolled at four university-affiliated general hospitals completed self-report questionnaires. Chi-square tests were used to compare the knowledge and attitude of registered or assistant nurses toward depression. In addition, binary logistic regression analysis was used to adjust for the following confounders: age-group and workplace. Registered and assistant nurses differed in their knowledge and attitude toward depression. The proportion of rational and/or correct responses were higher in registered nurses than assistant nurses for the following: constellation of depressive symptoms defined by DSM-IV (adjusted odds ratio [aOR], 3.876; P<0.001); suicide risk in depression recovery (aOR, 3.223; P=0.001) and psychological stress as a cause of depression (aOR, 4.370; P<0.001); the relationship between chronic physical disease and depression (aOR, 8.984; P<0.001); and other items. Our results suggest that in terms of the biological model of depression, the understanding of registered nurses is greater than that of assistant nurses. Moreover, specific psychiatric education programs for nursing personnel need to be developed in Korea. Our findings can contribute to the development of a general hospital-based model for early detection of depression in patients with chronic medical diseases.

ABSTRACT

BACKGROUND: Although cross-sectional studies have suggested a relationship between proton pump inhibitor (PPI) use and hypomagnesemia, no large-scale cohort study has been conducted to date. Here, we examined the changes in serum magnesium levels in response to PPI use. We hypothesized that PPI use might change the serum magnesium concentration. METHODS: Of the 2,892 patients hospitalized for percutaneous coronary intervention between January 2007 and May 2012, 1,076 patients with normal baseline (1.6-2.5 mg/dL) and follow-up serum magnesium concentrations were enrolled. These patients were divided into two groups: the PPI group and the control group. RESULTS: The mean follow-up period was 9.51+/-2.94 months. The incidence of hypomagnesemia ( or =12 months, n = 71) and short-term PPI groups (duration of use <12 months, n = 763), and the control group (n = 242; P = 0.620). The effect of PPI use on change in serum magnesium concentration was affected by the use of multiple diuretics (-0.01+/-0.25 mg/dL; P = 0.025), although a single diuretic use with PPI did not alter the change in magnesium level (0.12+/-0.27 mg/dL). CONCLUSION: Changes in magnesium levels might be subtle after PPI use in patients with normal baseline magnesium values.
