Sorafenib is currently the only targeted therapy available for advanced stage hepatocellular carcinoma (HCC). Cutaneous adverse events associated with sorafenib treatment include hand-foot skin reaction, but there has been no report of drug reaction (or rash) with eosinophilia and systemic symptoms (DRESS) syndrome. Here, we report a case of 72-year-old man with HCC and alcoholic liver cirrhosis who developed skin eruptions, fever, eosinophilia, and deteriorated hepatic and renal function under sorafenib treatment. He has since successfully recovered with conservative care.

PURPOSE: To investigate whether causes of anaphylaxis vary according to regions and seasons in Korean adults. METHODS: Based on previous retrospective studies of anaphylaxis between 2007 and 2011 at the 15 university hospitals. Regions were classified into 4 groups: region I, Seoul; region II, Gyeonggi; region III, Chungcheong; and region IV, Chonnam and Busan. The cases induced by 5 major allergens including drugs, food, bee sting, radiocontrast media, and exercise, were analyzed in the present study. RESULTS: Among a total of 1,661 cases reported (53% male, 45.9+/-16.0 years), 367 (22.2%), 706 (42.5%), 319 (19.2%), and 269 cases (16.2%) were enrolled in regions I, II, III, and IV, respectively. Of the 5 major allergens, drugs (37.3%) were the most frequently reported, followed by food (25.7%), bee sting (17.9%), radiocontrast media (12.9%), and exercise (6.2%). There was no significant difference in the total occurrence of anaphylaxis in 4 seasons (374 in spring, 460 in summer, 460 in autumn, and 367 in winter). Multiple logistic regression analysis revealed that drug-induced anaphylaxis was significantly associated with the winter season (odds ratio [OR] 1.0 vs. OR 0.597, P<0.05 for spring; OR 1.0 vs. OR 0.481, P<0.01 for summer; OR 1.0 vs. OR 0.653, P<0.05 for autumn). Food-associated anaphylaxis was mainly reported in region I, whereas the frequency of insect sting was relatively higher in regions II, III, and IV than in region I. Older age and female gender were significantly associated with drug-induced anaphylaxis. CONCLUSION: Specific causative allergens of anaphylaxis in adults may vary according to age, gender, region, and season in Korea.

The geriatric population is increasing, and asthma severity increases with age. We determined the predictors of asthma control, exacerbation, and the factors that affect asthma-specific quality of life (A-QOL) in elderly asthmatic patients. This was a prospective, multicenter, real-life study for 6 months with stepwise pharmacologic treatment based on the Global Initiative for Asthma (GINA) guideline. A total of 296 asthmatic patients aged > or = 60 yr were recruited from 5 university centers in Korea. The improved-asthma control group was defined as the group of patients who maintained well-controlled or improved disease and the not-improved asthma control group was defined as the remaining patients. Fewer number of medications for comorbidities (2.8 +/- 3.3 in the improved vs. 4.5 +/- 4.4 in the control) and higher physical functioning (PF) scale (89.8 +/- 14.2 in the improved vs. 82.0 +/- 16.4 in the control) were significant predictors in the improved-asthma control group (OR = 0.863, P = 0.004 and OR = 1.028, P = 0.018, respectively). An asthma control test (ACT) score of < or = 19 at baseline was a significant predictor of asthma exacerbation (OR = 3.938, P = 0.048). Asthma duration (F = 5.656, P = 0.018), ACT score (F = 12.237, P = 0.001) at baseline, and the presence of asthma exacerbation (F = 5.565, P = 0.019) were significant determinants of changes in A-QOL. The number of medications for comorbidities and performance status determined by the PF scale may be important parameters for assessing asthma control in elderly asthmatic patients.

PURPOSE: Differences in definitions of the condition, relevant triggers, and the geographical locations of study centers, cause estimates of the prevalence of anaphylaxis to vary. Recent epidemiological data indicate that the incidence of anaphylaxis is rising. METHODS: To investigate the causes and clinical features of anaphylaxis in Korean adults, factors associated with the severity of the condition, and serious outcomes, a retrospective medical record review was performed on adult patients diagnosed with anaphylaxis between 2007 and 2011 in 15 University Hospitals of South Korea. RESULTS: A total of 1,806 cases (52% male, age 16-86 years) were reported. Cutaneous symptoms (84.0%), combined with respiratory (53.9%) and/or cardiovascular (55.4%) symptoms, were the most frequent presentations. Using a recognized grading system, 1,776 cases could be classified as either mild, 340; moderate, 690; or severe, 746. Although eliciting factors varied significantly by age, gender, and regional and seasonal factors, drugs (46.5%; including nonsteroidal anti-inflammatory drugs, antibiotics, and radiocontrast media) were the most common cause of anaphylaxis, followed by foods (24.2%), insect stings (16.4%), exercise (5.9%), and unknown etiology (7.0%). All of age, multi-organ involvement, a history of allergic disease, and drug-induced anaphylaxis, were significant predictors of serious outcomes requiring hospital admission or prolongation of hospital stay. Epinephrine auto-injectors were prescribed for 7.4% of reported cases. CONCLUSIONS: The principal causes of anaphylaxis in Korean adults were drugs, food, and insect stings. Drug-associated anaphylaxis, a history of allergic disease, multi-organ involvement, and older age, were identified as predictors of serious outcomes.

PURPOSE: The objective of this study was to evaluate skills in handling inhalers and factors associated with these skills among patients with asthma who had undergone treatment at special asthma and allergy clinics in Korea. METHODS: We enrolled 78 subjects who used Turbuhaler and 145 who used Diskus for asthma control at special clinics in 10 university hospitals and visually assessed their skills in handling these inhalers. We also evaluated skills in 137 subjects who had used pressurized metered-dose inhalers (pMDIs) for symptom relief. Age, sex, duration of asthma and inhaler use, smoking status, monthly income, highest grade completed in school and previous instruction for handling inhalers were also measured to evaluate their association with overall inhaler skills. RESULTS: Performance grade was inadequate for 12.8% of participants using Turbuhaler, 6.2% for Diskus, and 23.4% for pMDIs. The success rates for each step in handling the inhalers were relatively high except for the "exhale slowly to residual volume" step, in which success rates ranged from 24.2% to 28.5%. Older age, male sex, lower educational grade, and absence of previous instruction for handling inhalers were associated with inadequate inhaler technique in univariate analysis; however, only older age and absence of previous instruction remained significant independent risk factors in multivariate analysis. CONCLUSIONS: Among Korean asthmatic patients in special asthma and allergy clinics, skills in handling their inhalers were mostly excellent; meanwhile, older age and absence of previous instruction for handling inhalers were associated with inadequate techniques.

Serum CA 125 is the most useful marker for monitoring patients with epithelial ovarian cancer. However, it can be elevated above normal level in a variety of conditions other than ovarian cancer such as endometriosis, pelvic inflammation disease, and other malignant or nonmalignant disorders, including pulmonary diseases. Recently, we experienced a case of bronchiectasis in which the serum CA 125 level was elevated, changing with the patient's condition. There was no evidence of underlying malignant disease on positron emission tomography or on gynecologic examination, including transvaginal ultrasonography. During follow-up for 14 months, we could not find any clue of malignant disease that could have been the cause of the elevated levels of serum CA 125. Elevated serum CA 125 level should be interpreted carefully according to the patient's clinical condition. In addition, our case suggests that CA 125 may be used as a surrogate marker for acute inflammatory status for chronic pulmonary diseases.

OBJECTIVES:To investigate mortality rates and predictors of mortality in dementia patients (prevalence cohort) resident at institution. METHODS:We followed up a dementia cohort for 5 years. A total of 273 subjects with dementia were longitudinally assessed at baseline, 6 months and 12 months and then checked whether alive or dead every 1 year for 5 years. Their mortality was compared with sociodemographic and clinical variables using Cochran-Mantel-Haenszel test and independent sample t-test. Survival time quartiles were used to describe the time until when 25%, 50%, and 75% of patients died. Kaplan Meier log-rank tests were used for testing the equality of survival among groups when identifying some disruptive agitated behaviors as mortality predictors. Relative risk (RR) with 95% confidence intervals were calculated by the Cox regression analysis. RESULTS:In this study, overall 5-year mortality rate was 63.0% (12.6% per year). Median survival after baseline evaluation was 2.85 years, whereas median survival after institutionalization was 6.42 years. Log-rank tests revealed that some disruptive behaviors (i.e., Cagras syndrome, screaming, trying to get to a different place, intentional falling) were significantly higher in the deceased group. Mortality in subjects with dementia depended on old age {over 85, relative risk (RR):1.04;95% confidence interval (CI):1.02-1.06}, male gender (RR:2.04;CI:1.28-3.25), lower MMSE-K score (RR:1.03;CI:1.00-1.06). CONCLUSION:We expect that this study may provide basic health information for health policy making in institutional care approaches in Korea

OBJECTIVE: This study estimated the expected cost-effectiveness ratio expressed as the incremental cost per seizure-free day (SFD) gained and the incremental cost per quality adjusted life year (QALY) gained when using levetiracetam (LEV) as add-on therapy from a third-party payer perspective. METHODS: A 1-year dose-escalation decision-tree model comparing LEV plus standard therapy (ST) with ST alone was designed to combine transition probabilities, costs and outcomes. The short-term outcomes and probabilities were derived from a prospective, open-label clinical trial with 100 Korean adults with refractory partial epilepsy. All data for the direct medical costs were derived from Korean cost data extracted from reports published by the National Health Insurance Corporation. RESULTS: The average gain in SFDs attributed to LEV add-on was 18.3 days per patient per year and the incremental cost-effectiveness ratios (ICERs) for LEV add-on were US$ 44 per SFD per patient and US$ 11,084 per QALY gained. All sensitivity analyses showed that the model was robust to the assumptions made. CONCLUSION: The economic evaluation indicates that, given a wide range of assumptions, the increased cost of treating patients having refractory partial epilepsy with LEV may be partially offset by a reduction in other direct medical costs. This reduction is a consequence of an increase in the number of SFDs and improved quality of life.

Minoxidil induces hair growth in male pattern baldness and prolongs the anagen phase. All-trans retinoic acid (ATRA) has been reported to act synergistically with minoxidil in vivo: they can enhance more dense hair regrowth than either compound alone. We evaluated the effect of minoxidil combined with ATRA on hair growth in vitro. The effect of co-treatment of minoxidil and ATRA on hair growth was studied in hair follicle organ culture. In cultured human dermal papilla cells (DPCs) and normal human epidermal keratinocytes, the expressions of Erk, Akt, Bcl-2, Bax, P53 and P21 were evaluated by immunoblot analysis. Minoxidil plus ATRA additively promoted hair growth in vitro, compared with minoxidil alone. In addition, minoxidil plus ATRA elevated phosphorylated Erk, phosphorylated Akt and the ratio of Bcl-2/Bax, but decreased the expressions of P53 and P21 more effectively than by minoxidil alone. Our results suggest that minoxidil plus ATRA would additively enhance hair growth by mediating dual functions: 1) the prolongation of cell survival by activating the Erk and Akt signaling pathways, and 2) the prevention of apoptosis of DPCs and epithelial cells by increasing the ratio of Bcl-2/Bax and downregulating the expressions of P53 and P21.

Pilomatrixoma, calcifying epithelioma, is a benign neoplasm that arises from hair follicle matrix cells and a common skin neoplasm that is often misdiagnosed as other skin condition. Our study is to examine the clinical & histopathological presentation, and management of pilomatrixoma. We conducted a 4 year retrospective study of 102 patients who had a confirmed histopathologic diagnosis of pilomatrixoma. The symptom was a slowly growing, rock-hard, solitary, superficial mass in the head(64.5%), neck(14.0%) and upper extremities(12.2%). Male-to-female ratio was 1:1.3 and the mean age of patients was 13.2 years. The mean tumor size in greatest dimension was 1.3cm and the overlying skin was slightly reddish or bluish and slightly elevated than surrounding normal skin. The excised mass was relatively well encapsulated and showed multiple nodularity and calcification. The preoperative diagnosis was accurate and consistent with the pathological diagnosis of pilomatrixoma only in 38 cases (35.5%), and the most often preoperative diagnosis were unidentified mass(43%) with inclusion of 8 other possible diagnoses. All masses were treated with surgical excision without recurrence. This entity should be considered with other neoplasm in the clinical differential diagnosis of solitary firm skin nodules, especially those on head, neck, or upper extremities in young children. The results of our study was in accordance with previously published literatures and we agree that surgical excision is the treatment of choice and the recurrence rate is low.
