Acute generalized exanthematous pustulosis presumed to be caused by acetaminophen

Acute generalized exanthematous pustulosis (AGEP) is a severe and rare disease usually related to drug eruption. AGEP is induced by drugs in over 90% of cases with antibiotics being the most common. It is characterized by a fever and a pustular eruption on erythematous skin with acute onset and without follicular localization. Acetaminophen is commonly used as an antipyretic and analgesic. Acetaminophen has been reported to be an uncommon cause of AGEP. We report a 79-year-old woman presenting with fever and erythematous maculopapular eruptions on the trunk with sterile pustules arising upon the use of acetaminophen for back pain. Leukocytosis and elevated C-reactive protein levels were noted on the laboratory examination. The histopathological examination of the skin biopsy specimen showed intraepidermal pustule formation with superficial perivascular lymphocytic infiltration, including eosinophils, and extensive red blood cell extravasation. The lesions were resolved with discontinuation of acetaminophen and use of systemic corticosteroid. We report a case of AGEP probably caused by acetaminophen.

Effects of vitamin D deficiency and daily calcium intake on bone mineral density and osteoporosis in Korean postmenopausal woman

OBJECTIVE: We evaluated the combined effects of vitamin D and daily calcium intake on bone mineral density (BMD) and osteoporosis in Korean postmenopausal women. METHODS: This study is a cross-sectional study consisting of 1,921 Korean postmenopausal women aged 45 to 70 years without thyroid dysfunction, from the 2008–2011 Korean National Health and Nutrition Examination Survey. Participants were classified into six groups according to serum 25-hydroxyvitamin D (25(OH)D) levels and daily calcium intake. BMD was measured using dual-energy X-ray absorptiometry at femur and at lumbar spine, and the serum vitamin D levels were measured by radioimmunoassay. RESULTS: The BMD divided according to serum 25(OH)D and daily calcium intakes were not statistically different among the groups. However, when both daily calcium intake and serum 25(OH)D were not sufficient, risk of osteopenia and osteoporosis showed significant increase in both femur neck and lumbar spine (odds ratio [OR] 2.242, P=0.006; OR 3.044, P=0.001; respectively). Although daily calcium intake was sufficient, risks of osteopenia and osteoporosis significantly increased in lumbar spine group if serum 25(OH)D is <20 ng/mL (OR 2.993, P=0.006). CONCLUSION: The combined effects of insufficient daily calcium intake and vitamin D deficiency may cause low BMD and increase in prevalence of osteopenia and osteoporosis in Korean postmenopausal women aged 45 to 70 years.

Obesity and hepatocellular carcinoma in patients receiving entecavir for chronic hepatitis B

BACKGROUND/AIMS: This study aimed to clarify the effect of obesity on the development of hepatocellular carcinoma (HCC) in chronic hepatitis B (CHB) patients receiving antiviral treatment. METHODS: This study applied a retrospective analysis to a historical cohort in Bundang Jesaeng Hospital. In total, 102 CHB patients were treated with entecavir as an initial treatment for CHB and checked for obesity using a body composition analyzer. Hepatic steatosis was measured semiquantitatively using Hamaguchi’s scoring system in ultrasonography. Risk factors for the development of HCC were analyzed, including obesity-related factors (body mass index [BMI], waist circumference [WC], waist-to-hip ratio [WHR], visceral fat area [VFA], and hepatic steatosis). RESULTS: The median follow-up duration of the patients was 45.2 months (interquartile range: 36.0-58.3 months). The cumulative incidence rates of HCC at 1 year, 3 years, and 5 years were 0%, 5.3%, and 9.0%, respectively. Univariable analysis revealed that the risk factors for HCC development were a platelet count of <120,000 /mm² (hazard ratio [HR]=5.21, P=0.031), HBeAg negativity (HR=5.61, P=0.039), and liver cirrhosis (HR=10.26, P=0.031). Multivariable analysis showed that the significant risk factor for HCC development was liver cirrhosis (HR=9.07, P=0.042). However, none of the obesity-related risk factors were significantly associated with HCC: BMI ≥25 kg/m² (HR=0.90, P=0.894), WC ≥90 cm (HR=1.10, P=0.912), WHR ≥0.9 (HR=1.94, P=0.386), VFA ≥100 cm² (HR=1.69, P=0.495), and hepatic steatosis (HR=0.57, P=0.602). CONCLUSION: HCC development is associated with liver cirrhosis but not obesity-related factors in CHB patients receiving entecavir.

Subacute Thyroiditis and Painless Thyroiditis: Clinical Characteristics of 221 Patients Diagnosed between 2009 and 2015

BACKGROUND AND OBJECTIVES: In the past, subacute thyroiditis causing thyrotoxicosis included both painful and painless subgroup, but it is representative for the painful subacute thyroiditis these days. So we evaluated the clinical and laboratory characteristics of subacute thyroiditis and compared with the painless (silent) thyroiditis, and identified predictive factors of permanent hypothyroidism and recurrence. MATERIALS AND METHODS: This was a retrospective case series study analyzing clinical data of 221 consecutive patients diagnosed between 2009 and 2015. Medical records were reviewed for diagnostic route, age distribution, laboratory data, clinical course and long-term follow up outcome. RESULTS: The mean age was 48 years; female v/s male ratio 3.4:1. Median disease duration was 110 days; mean peak free T4 level was 2.9 ng/dL. 56.7% of painless thyroiditis patients were diagnosed on health checkup or routine thyroid function test with symptoms not typically associated with thyrotoxicosis. Permanent hypothyroidism was not uncommon (11/221; 5.0%). Higher peak thyroid-stimulating hormone (TSH) was associated with permanent hypothyroidism in painless thyroiditis. Lower peak TSH was associated with recurrence rate in both subacute and painless thyroiditis. In painless thyroiditis, short duration of thyrotoxicosis phase was also associated with recurrence rate. CONCLUSION: Considerable numbers of painless thyroiditis without symptoms were diagnosed on health checkup. Higher peak TSH was associated with permanent hypothyroidism in painless thyroiditis. Recurrence rate was related with lower peak TSH in both groups.

Serum Thyroid Stimulating Hormone Levels Are Associated with the Presence of Coronary Atherosclerosis in Healthy Postmenopausal Women

OBJECTIVES: Menopause is a natural aging process causing estrogen deficiency, accelerating atherogenic processes including dyslipidemia. Prevalence of thyroid dysfunction is also high in postmenopausal women, and it is known to elevate the risk of cardiovascular disease (CVD). Therefore, we are to study on the associations in between serum thyroid stimulating hormone (TSH) and prevalence of CVD in postmenopausal women who have normal thyroid function. METHODS: We performed a retrospective review of 247 Korean postmenopausal women who visited the health promotion center from January, 2007 to December, 2009. Postmenopausal women with normal serum TSH were included in the study. Coronary atherosclerosis was assessed by 64-row multidetector computed tomography. RESULTS: In multiple linear regression analysis, serum TSH was associated with serum triglyceride (TG) (β = 0.146, P = 0.023). In multiple logistic regression analysis, increasing age and serum TSH were associated with an increased risk of coronary atherosclerosis in euthyroid postmenopausal women (odds ratio [OR] = 1.107 [1.024-1.197], P = 0.011 and OR = 1.303 [1.024-1.658], P = 0.031, respectively). CONCLUSIONS: It revealed that significant predictor of serum TSH was serum TG, and increasing age and TSH were found to have associations with an increased risk of coronary atherosclerosis in euthyroid postmenopausal women. Screening and assessing risks for CVD in healthy postmenopausal women would be helpful before atherosclerosis develops.

The Efficacy and Safety of Cordyceps militaris in Korean Adults Who Have Mild Liver Dysfunction

PURPOSE: The aim of this study is to determine the efficacy and safety of Cordyceps militaris in Korean adults with mild liver dysfunction. C. militaris is a mushroom traditionally used for several clinical purposes in East Asian territory, including China, and has been found to be effective in improving liver function through animal studies. METHODS: The C. militaris group was administered 1.5 g/day of C. militaris (2 capsules per dose, twice per day) and the placebo group was administered the same volume of placebo. Laboratory test (white blood cell, hemoglobin, platelet, aspartate aminotransferase, alanine aminotransferase, gamma glutamyltranspeptidase, lactic dehydrogenase, alkaline phosphatase, total bilirubin, blood urea nitrogen, creatinine), liver computed tomography (CT) were performed, and visual analogue scale score for subjective symptoms and fatigue severity scale were measured. RESULTS: In analysis of the liver CT scan at 8 weeks after administration compared to baseline, the mean ratio of change of Hounsfield unit of 8 segments of liver increased by an average of 21.43%+/-45.11% in the C. militaris group and 9.64%+/-11.41% in the placebo group. Others showed no statistically significant inter-group difference. CONCLUSION: C. militaris extract was used safely as a functional food in patients with mild liver dysfunction, and is expected to protect against progression of fatty liver or cirrhosis caused by suppression of lipid accumulation in hepatocytes.
