Background: Aromatase inhibitors (AIs) play an important role in the endocrine therapy of postmenopausal breast cancer patients, with a recent tendency to extend the duration of their use. However, AIs may increase the risk of osteoporotic bone fractures. This meta-analysis evaluated the risk of osteoporotic fractures of the hip, spine, and other locations in breast cancer patients using AIs. Methods: We performed a systematic search to identify randomized controlled clinical trials that investigated osteoporotic fractures in breast cancer patients on AI therapy. The main outcomes were the incidence and risk of osteoporotic fractures in general and of hip, vertebral, and non-vertebral fractures in AI users and controls. Results: The systematic review found a total of 30 randomized controlled trials including 117,974 participants. The meta-analysis showed a higher incidence of osteoporotic fracture in AI users: The crude risk ratio for all osteoporotic fractures was 1.35 (95% confidence interval [CI], 1.29–1.42;P < 0.001), for hip fractures 1.18 (95% CI, 1.02–1.35; P < 0.001), for vertebral fractures 1.84 (95% CI, 1.36–2.49; P < 0.001), and for non-vertebral fractures 1.18 (95% CI, 1.02–1.35; P < 0.001), respectively, compared to the controls. Conclusion Our meta-analysis suggested an increased risk of osteoporotic fractures for AI therapy in patients with breast cancer that was most expressed for vertebral fractures. Breast cancer patients on AIs need to be monitored for osteoporosis and osteoporotic fractures, and active prevention measures should be implemented.

PURPOSE: To estimate annual health care and productivity loss costs attributable to overweight or obesity in working asthmatic patients. MATERIALS AND METHODS: This study was conducted using the 2003–2013 Medical Expenditure Panel Survey (MEPS) in the United States. Patients aged 18 to 64 years with asthma were identified via self-reported diagnosis, a Clinical Classification Code of 128, or a ICD-9-CM code of 493.xx. All-cause health care costs were estimated using a generalized linear model with a log function and a gamma distribution. Productivity loss costs were estimated in relation to hourly wages and missed work days, and a two-part model was used to adjust for patients with zero costs. To estimate the costs attributable to overweight or obesity in asthma patients, costs were estimated by the recycled prediction method. RESULTS: Among 11670 working patients with a diagnosis of asthma, 4428 (35.2%) were obese and 3761 (33.0%) were overweight. The health care costs attributable to obesity and overweight in working asthma patients were estimated to be $878 [95% confidence interval (CI): $861–$895] and $257 (95% CI: $251–$262) per person per year, respectively, from 2003 to 2013. The productivity loss costs attributable to obesity and overweight among working asthma patients were $256 (95% CI: $253–$260) and $26 (95% CI: $26–$27) per person per year, respectively. CONCLUSION: Health care and productivity loss costs attributable to overweight and obesity in asthma patients are substantial. This study's results highlight the importance of effective public health and educational initiatives targeted at reducing overweight and obesity among patients with asthma, which may help lower the economic burden of asthma.

Quantification of quality of life (QOL) related to disease severity is important in patients with atopic dermatitis (AD), because the assessment provides additional information to the traditional objective clinical scoring systems. To document the impact of AD on QOL for both children and adults as well as to quantify the relationship with disease severity, QOL assessments were performed over a 6-month period on 415 patients with AD. A questionnaire derived from the Infants' Dermatitis Quality of Life Index (IDQOL), the Children's Dermatology Life Quality Index (CDLQI) and the Dermatology Life Quality Index (DLQI) was used to determine the QOL for 71 infants, 197 children and 147 adults, respectively. To measure AD severity, both the Rajka & Langeland scoring system and the Scoring of Atopic Dermatitis (SCORAD) index were used. The mean scores were as follows: 7.7 +/- 5.5 for IDQOL, 6.6 +/- 6.3 for CDLQI, and 10.7 +/- 7.9 for DLQI. In conclusion, these QOL scores are correlated with AD severity scores as estimated by the Rajka & Langeland severity score and the SCORAD. The outcome of the QOL instruments in this study demonstrates that atopic dermatitis of both children and adults affects their QOL.

BACKGROUND: Atopic dermatitis (AD) is a chronic, relapsing inflammatory skin disease with genetic and environmental backgrounds. While the prevalence of AD is increasing, many patients lack accurate information and understanding about AD. OBJECTIVE: This study was performed to investigate the understanding of AD among Korean AD patients. METHODS: We developed a survey instrument to assess patient understanding of AD. Surveys were conducted over a 6-month period (from May 2010 to October 2010) among 415 patients with AD who visited 10 dermatology clinics at a university teaching hospital affiliated with the Korean Atopic Dermatitis Association. RESULTS: We identified points of understanding in Korean AD patients, such as knowledge and attitudes about AD, awareness of AD treatment, reliability of health care providers and information sources, and acting with AD treatment. As the results of this survey, it was confirmed that the patients' understanding of the cause and prognosis of AD was relatively inadequate, and it could be seen that the perception of the negative attitude toward the medical treatment of AD and inconveniences caused by AD was high. However, the results of the survey on the perception about the medical treatment methods of AD showed that they perceived medical doctors' treatment and prescriptions to have the best curative value, and as the criteria for choosing the treatment methods for AD, they chose the curative value rather than safety and cost. With regard to the information source for AD, they evaluated the treatment postscript on the internet sites and reliability of news media more highly than other information sources, and they responded that the main channel through which they obtain information related to AD was the medical doctors' explanations. CONCLUSION: We conducted the first systematic questionnaire survey to assess the understanding of AD among Korean AD patients. The results of this survey indicate that in the education and promotion on AD patients, additional education with regard to the cause and prognosis of AD is needed, and it is considered that efforts should be made to reduce the negative perception of AD through smooth communication with the medical team. In education and promotion related to AD, treatment postscripts on news media and the internet sites should also be addressed. Ultimately, the patients' self-discipline capabilities should be reinforced through proper education and development of programs related to AD.

PURPOSE: In some girls with central precocious puberty (CPP), growth velocity (GV) decreases below the age-appropriate normal range during gonadotropin-releasing hormone agonist (GnRHa) treatment. The purpose of this study was to investigate clinical and laboratory factors related to changes in GV during GnRHa treatment in girls with CPP. METHODS: We analyzed clinical and laboratory data of 49 girls (aged 7.8+/-0.5 years) with idiopathic CPP who were treated with GnRHa. GV, height standard deviation score (SDS), hormonal parameters, pubertal stage, chronological age and bone age (BA) were evaluated. RESULTS: GV during the first year of GnRHa treatment was 5.9+/-1.0 cm/yr and decreased significantly to 5.4+/-1.1 cm/yr during the second year of treatment (P = 0.005). GV during the third year (5.0+/-1.0 cm/yr) was not different from GV during the second year. During the second year of treatment, 8.2% and 36.7% of the girls had a GV < 4 cm/yr and < 5 cm/yr, respectively. Girls with relatively low GV during the second year of treatment (< 5 cm/yr) showed higher risk of advanced BA (> or = 11 yr) at 1 year (55.6% vs. 19.4%; odds ratio [OR], 5.2; P = 0.022). In multivariate logistic regression analysis, more advanced BA at 1 year (OR, 6.1; 95% confidence interval [CI], 1.57-23.87) and lower height SDS for BA at 1 year (OR, 0.24; 95% CI, 0.06-0.94) were associated with relatively decreased GV (< 5 cm/yr) during the second year of GnRHa treatment. CONCLUSION: GV during and after the second year of GnRHa treatment in girls with idiopathic CPP remains within the normal prepubertal range, and relatively low GV during GnRHa treatment is associated with more advanced BA and lower height SDS for BA.

PURPOSE: Dexmedetomidine, a full agonist of alpha2B-adrenoceptors, is used for analgesia and sedation in the intensive care units. Dexmedetomidine produces an initial transient hypertension due to the activation of post-junctional alpha2B-adrenoceptors on vascular smooth muscle cells (SMCs). The aims of this in vitro study were to identify mitogen-activated protein kinase (MAPK) isoforms that are primarily involved in full, alpha2B-adrenoceptor agonist, dexmedetomidine-induced contraction of isolated rat aortic SMCs. MATERIALS AND METHODS: Rat thoracic aortic rings without endothelium were isolated and suspended for isometric tension recording. Cumulative dexmedetomidine (10(-9) to 10(-6) M) dose-response curves were generated in the presence or absence of extracellular signal-regulated kinase (ERK) inhibitor PD 98059, p38 MAPK inhibitor SB 203580, c-Jun NH2-terminal kinase (JNK) inhibitor SP 600125, L-type calcium channel blocker (verapamil and nifedipine), and alpha2-adrenoceptor inhibitor atipamezole. Dexmedetomidine-induced phosphorylation of ERK, JNK, and p38 MAPK in rat aortic SMCs was detected using Western blotting. RESULTS: SP 600125 (10(-6) to 10(-5) M) attenuated dexmedetomidine-evoked contraction in a concentration-dependent manner, whereas PD 98059 had no effect on dexmedetomidine-induced contraction. SB 203580 (10(-5) M) attenuated dexmedetomidine-induced contraction. Dexmedetomidine-evoked contractions were both abolished by atipamezole and attenuated by verapamil and nifedipine. Dexmedetomidine induced phosphorylation of JNK and p38 MAPK in rat aortic SMCs, but did not induce phosphorylation of ERK. CONCLUSION: Dexmedetomidine-induced contraction involves a JNK- and p38 MAPK-mediated pathway downstream of alpha2-adrenoceptor stimulation in rat aortic SMCs. In addition, dexmedetomidine-induced contractions are primarily dependent on calcium influx via L-type calcium channels.

BACKGROUND: The intravenous administration of indigo carmine has been reported to produce transiently increased blood pressure in patients. The goal of this in vitro study was to examine the effect of indigo carmine on phenylephrine-induced contractions in an isolated rat aorta and to determine the associated cellular mechanism with particular focus on the endothelium-derived vasodilators. METHODS: The concentration-response curves for phenylephrine were generated in the presence or absence of indigo carmine. Phenylephrine concentration-response curves were generated for the endothelium-intact rings pretreated independently with a nitric oxide synthase inhibitor, Nomega-nitro-L-arginine methyl ester (L-NAME), a cyclooxygenase inhibitor, indomethacin, and a low-molecular-weight superoxide anion scavenger, tiron, in the presence or absence of indigo carmine. The fluorescence of oxidized dichlorofluorescein was measured in rat aortic vascular smooth muscle cells cultured in the control, indigo carmine alone and tiron plus indigo carmine. RESULTS: Indigo carmine (10(-5) M) increased the phenylephrine-induced maximum contraction in the endothelium-intact rings with or without indomethacin, whereas indigo carmine produced a slight leftward shift in the phenylephrine concentration-response curves in the endothelium-denuded rings and L-NAME-pretreated endothelium-intact rings. In the endothelium-intact rings pretreated with tiron (10(-2) M), indigo carmine did not alter phenylephrine concentration-response curves significantly. Indigo carmine (10(-5) M) increased the fluorescence of oxidized dichlorofluorescein in the vascular smooth muscle cells, whereas tiron abolished the indigo carmine-induced increase in oxidized dichlorofluorescein fluorescence. CONCLUSIONS: Indigo carmine increases the phenylephrine-induced contraction mainly through an endothelium-dependent mechanism involving the inactivation of nitric oxide caused by the increased production of reactive oxygen species.

BACKGROUND: Dermatological diseases can occur with atopic dermatitis. OBJECTIVE: The purpose of this study was to analyze diseases associated with atopic dermatitis in Koreans. METHODS: From November, 2007, to May, 2008, 948 patients with atopic dermatitis who visited the department of dermatology at 19 hospitals were evaluated for associated diseases. RESULTS: Of 948 patients, 53.8% (510) had symptoms associated with other dermatological diseases. In order of frequency, diseases associated with atopic dermatitis included acne, hand/foot eczema, seborrheic dermatitis, urticaria, warts, and recurrent herpes simplex. The number of associated diseases did not change significantly with the severity of atopic dermatitis. However, the incidence of hand/foot eczema and eczema herpeticum correlated significantly with the severity of atopic dermatitis. CONCLUSION: There is a distinct pattern of diseases associated with atopic dermatitis in Koreans.
