Purpose: A total of 39 seafood menus were prepared according to the Korean standard recipe, and analyzed for vitamin B 9 (folate) and B 12 (cobalamins) contents, using validated applied analytical methods. The menus included Guk/Tang/Jjigae (boiled or stewed dishes, n = 10), Bokkeum (stir-fried dishes, n = 10), Jjim/Jorim (braised or steamed dishes, n = 7), Gui (baked or grilled dishes, n = 7), Twigim (deep-fried dishes, n = 2) and Muchim (dried or blanchedseasoned dishes, n = 3). Methods: The contents of vitamin B 9 and B12 in all food samples were determined by the trienzyme extraction-Lactobacillus casei and immunoaffinity-high-performance liquid chromatography/photodiode array detection methods. Analytical quality control was performed in order to assure reliability of the analysis. Results: Accuracy (97.4–100.6% recoveries) and precision (< 6% relative standard deviations for repeatability and reproducibility) of vitamin B 9 and B12 analyses were determined to be excellent. The vitamin B 9 and B 12 contents of the 39 seafood menus evaluated, varied in the range of 1.83–523.08 μg/100 g and 0.11–38.30 μg/100 g, respectively, depending on the ingredients and cooking methods. The vitamin B 9 content was highest in Jomi-gim (523.08 μg/100 g), followed by Geonsaeu-bokkeum (128.34 μg/100 g) and Janmyeolchi-bokkeum (121.53 μg/100 g). Vitamin B12 was detected in all seafood menus, with highest level obtained in Kkomack-jjim (41.58 μg/100 g). The seaweed dish was found to have high levels of both vitamin B 9 and B12 . All assays were performed under strict quality control. Conclusion Guk and Tang menus, which contain a large amount of water, were relatively lower in the vitamin B 9 and B12 contents than the other menus. Bokkeum menus containing various vegetables were high in the vitamin B 9 content, but the vitamin B12 content was dependent on the type of seafood used in the menu.

OBJECTIVE : To evaluate the vitamin D nutritional status and its influencing factors in Korean mothers and their newborn infants. METHODS : Maternal (n=181) and cord blood (n=180) serum concentrations of vitamin D (25OHD3), calcium, inorganic phosphorus, alkaline phosphatase, intact parathyroid hormone were measured at the time of delivery. We defined vitamin D deficient, insufficient, and sufficient as 25OHD3 <11, 11~30, and >30 ng/mL, respectively. Using questionnaires, average duration of sun-light exposure (minutes/day) and dietary intake of vitamin D (microngram/day) were obtained. RESULTS : 1) The mean 25OHD3 level in mothers was 23.4+/-9.9 (range 4~71.6) ng/mL, and in newborns, 16.9+/-7.5 (range 0.9~53.6) ng/mL. 2) 8.3% of mothers and 22.2 % of newborns were vitamin D deficient, and 70% of both mothers and newborns were insufficient. 3) Maternal 25OHD3 showed a strong positive correlation with cord blood 25OHD3 (r=0.727, p<0.001). 4) The most significant risk factor for low 25OHD3 levels was the season of birth (June through November) in both mothers and newborns. 5) In multiple logistic regression analysis, the season of birth and the mode of delivery remained significant for maternal vitamin D status, whereas maternal 25OHD3 and the mode of delivery remained significant for neonatal vitamin D status. CONCLUSION : In conclusion, vitamin D deficiency or insufficiency was relatively common in Korean mothers and their newborn infants, and the most significant risk factor for low vitamin D status was the season of birth.

Tumor necrosis factor (TNF) inhibitors are increasingly used in treatment of rheumatoid arthritis (RA), ankylosing spondylitis, psoriatic arthritis, and inflammatory bowel diseases including Crohn's disease and ulcerative colitis. Rarely, anti-TNF therapy is associated with neurological complications, including both central and peripheral nervous system disorders. To the best of our knowledge, only one case of infliximab-associated multifocal motor neuropathy with conduction block in a patient with spondyloarthropathy has been reported to date in Korea. Here, we report on the case of a 58-year-old Korean woman affected by RA who developed multifocal motor neuropathy after infliximab treatment.

Pyrazinamide (PZA) is an anti-tuberculosis drug and an essential component of the standard four-drug regimen for tuberculosis. Here, we report a case of immediate angioedema secondary to PZA administration intended for pulmonary tuberculosis treatment. A previously healthy 48-year-old woman was diagnosed with pulmonary tuberculosis and tuberculous lymphadenitis. Thirty minutes after taking the first dose of isoniazid, rifampicin, pyrazinamide, and ethambutol, the patient developed facial edema, generalized rash, and dizziness. An oral provocation test was performed on the four drugs, and 1,000 mg pyrazinamide showed a positive result characterized by 50 minutes of urticaria, angioedema, and hypotension. As the prevalence of tuberculosis increases, prescriptions for anti-tuberculosis drugs may increase as well. Clinicians should be aware of the possibility of immediate hypersensitivity as well as delayed hypersensitivity to anti-tuberculosis drugs.

The current multimorbidity correction method in the Global Burden of Disease studies assumes the independent occurrence of diseases. Those studies use Monte-Carlo simulations to adjust for the presence of multiple disease conditions for all diseases. The present study investigated whether the above-mentioned assumption is reasonable based on the prevalence confirmed from actual data. This study compared multimorbidity-adjusted years of lived with disability (YLD) obtained by Monte-Carlo simulations and multimorbidity-adjusted YLD using multimorbidity prevalence derived from National Health Insurance Service data. The 5 most common diseases by sex and age groups were selected as diseases of interest. No significant differences were found between YLD estimations made using actual data and Monte-Carlo simulations, even though assumptions about the independent occurrence of diseases should be carefully applied. The prevalence was not well reflected according to disease characteristics in those under the age of 30, among whom there was a difference in YLD between the 2 methods. Therefore, when calculating the burden of diseases for Koreans over the age of 30, it is possible to calculate the YLD with correction for multimorbidity through Monte-Carlo simulation, but care should be taken with under-30s. It is useful to apply the efficiency and suitability of calibration for multiplicative methods using Monte-Carlo simulations in research on the domestic disease burden, especially in adults in their 30s and older. Further research should be carried out on multimorbidity correction methodology according to the characteristics of multiple diseases by sex and age.

Blastic plasmacytoid dendritic cell neoplasm (BPDCN) is a relatively rare hematological malignancy, and most cases present with characteristic skin lesions. The skin lesions appear as nodules, plaques, and bruise-like macules with redness or ulcerations. BPDCN without skin lesions is rare. Cases with hepatosplenomegaly, pulmonary involvement, multiple lymphadenopathies, renal masses, sinonasal sinus, and subcutaneous masses have also been reported. Here, we report the first case of ileocecal valve involvement of BPDCN without skin lesions.

OBJECTIVES: Alcohol consumption is a well-established risk factor for cancer. Despite extensive research into the relationship between alcohol consumption and cancer risk, the effect of light alcohol consumption on cancer risk remains a topic of debate. To contribute to this discourse, we conducted a comprehensive systematic review and meta-analysis. METHODS: Our systematic review aimed to investigate the associations between different levels of alcohol consumption and the risk of several cancer types. We focused on analyzing prospective associations using data from 139 cohort studies. Among them, 106 studies were included in the meta-analysis after a quantitative synthesis. RESULTS: Our analysis did not find a significant association between light alcohol consumption and all-cause cancer risk (relative risk, 1.02; 95% confidence interval, 0.99 to 1.04), but we observed a dose-response relationship. Light alcohol consumption was significantly associated with higher risks of esophageal, colorectal, and breast cancers. Light to moderate drinking was associated with elevated risks of esophageal, colorectal, laryngeal, and breast cancers. Heavy drinking was also found to contribute to the risk of stomach, liver, pancreas, and prostate cancers, thereby increasing the risk of almost all types of cancer. Additionally, females generally had lower cancer risks compared to males. CONCLUSIONS Our findings highlight that cancer risks extend beyond heavy alcohol consumption to include light alcohol consumption as well. These findings suggest that there is no safe level of alcohol consumption associated with cancer risk. Our results underscore the importance of public health interventions addressing alcohol consumption to mitigate cancer risks.

We investigated the vitamin D status and the effect of vitamin D supplementation in Korean breast-fed infants. The healthy term newborns were divided into 3 groups; A, formula-fed; B, breast-fed only; S, breast-fed with vitamin D supplementation. We measured serum concentrations of vitamin D (25OHD3), calcium (Ca), phosphorus (P), alkaline phosphatase (AP), intact parathyroid hormone (iPTH) and bone mineral density (BMD) at 6 and 12 months of age. Using questionnaires, average duration of sun-light exposure and dietary intake of vitamin D, Ca and P were obtained. At 6 and 12 months of age, 25OHD3 was significantly higher in group S than in group B (P<0.001). iPTH was significantly lower in group S than in group B at 6 months (P=0.001), but did not differ at 12 months. Regardless of vitamin D supplementation, BMD was lower in group B and S than in group A (P<0.05). Total intake of vitamin D differed among 3 groups (P<0.001, A>S>B), but total intake of Ca and P were higher in group A than in group B and S (P<0.001). In conclusion, breast-fed infants show lower vitamin D status and bone mineralization than formula-fed infants. Vitamin D supplementation (200 IU/day) in breast-fed infants increases serum 25-OH vitamin D3, but not bone mineral density.

Toxocariasis is an important cause of secondary hypereosinophilia in Korea. Here, we describe a rare case of toxocariasis presenting as transient global amnesia due to secondary hypereosinophilia. A 44-year-old male visited the Emergency Department (ED) for transient global amnesia. He ate raw cow liver and omasum 2 weeks before the ED visit. The initial peripheral blood eosinophil count was 15,250/µL and serologic test for serum specific IgG antibodies to Toxocara canis larval antigen was positive. Radiologic studies revealed multiple small embolic infarctions of brainwithout cardioembolic sources or vascular abnormalities. He was treated with systemic corticosteroid, and neither neurologic deficit nor motor deficit was left. In our current case, the patient have a history of frequently eating raw cow liver and omasum, and his total IgE level was extremely high (>5,000 IU/mL). Thus, the patient was diagnosed as having toxocariasis and secondary hypereosinophilia. Toxocariasis should be considered in the differential diagnosis in patients with eosinophilia and atypical neurologic symptoms, such as transient amnesia.

Hypercalcemia is a common clinical problem. The most frequent causes of hypercalcemia include primary hyperparathyroidism and malignancy; systemic lupus erythematosus (SLE) is a very rare cause of hypercalcemia. Here we describe a case of symptomatic severe hypercalcemia, which developed during a lupus flare. After treatment with intravenous fluids, diuretics, pamidronate, and hemodialysis, calcium levels normalized and were maintained on low-dose prednisolone treatment. To the best of our knowledge, this is the first case of hypercalcemia in a patient with SLE in Korea. Clinicians should consider lupus as a differential diagnosis for patients with severe hypercalcemia.
