BACKGROUND: Excessive iodine intake increases the occurrence of autoimmune thyroid disorders by enhancing immunogenecity of iodine-rich thyroglobulin, In Korea, most of postpartum women take a large amount of iodine-rich seaweed. Although the excessive iodine intake may affect the thyroid function, only a few reports were available concering iodine intake, especially on postpartum period. METHODS: A prospective study was undertaken in 146 of normal delivered postpartum women. Dietary intake and urinary excretion of iodine, serum T3, T4, TSH, anti-TPO Ab and anti-Tg Ab were measured before and 1, 6, 12 and 24 weeks after delivery. Iodine intake was analyzed by one-to-one interview using 24hr recall and food frequency questionnaire. RESULTS: 1. PPT was occurred in 6 (10.3%) postparturn women, It presented as hypothyroidism alone in 1 (16.7%), transient thyrotoxicosis followed by hypothyroidisrn in 3 (50.0%), and thyrotoxicosis alone in 2 (33.3%) of the follwed-up patients. 2. During pregnancy, no difference was found in age, serum T3, T4 and TSH between PPT and normal thyroid function group. 3. In PPT group, anti-TPO and anti-Tg Ab were significantly higher than those of normal thyroid function group during pregnancy, and their sensitivity for PPT was 40% and 33%, respectively. But there was no correlation between dietary iodine intake and the titer of thyroid auto-antibodies. 4. There was no correlation between pre and post-partum dietary iodine intake and occurrence of PPT. CONCLUSION: In Korea, the incidence of PPT was slightly higher than other nations. The sensitivity of thyroid auto-antibodies was too low to use for prediction of PPT. Pre and post-partum iodine intake had no effect on the occurrence of PPT and post-partum thyroid function.

BACKGROUND: Skin-sparing mastectomy with immediate breast reconstruction is increasingly becoming a proven surgical option for early-stage breast cancer patients. Areola-sparing mastectomy (ASM) has also recently become a popular procedure. The purpose of this article is to investigate the reconstructive and aesthetic issues experienced with one-stage nipple and breast reconstruction using ASM. METHODS: Among the patients who underwent mastectomy between March 2008 and March 2010, 5 women with a low probability of nipple-areolar complex malignant involvement underwent ASM and immediate breast reconstruction with simultaneous nipple reconstruction using the modified C-V flap. The cosmetic outcomes of this series were reviewed by plastic surgeons and patient self-assessment and satisfaction were assessed via telephone interview. RESULTS: During the average 11-month follow-up period, there were no cases of cancer recurrence, the aesthetic outcomes were graded as excellent to very good, and all of the patients were satisfied. Two patients developed a gutter-like depression around the reconstructed nipple, and one patient developed skin erosion in a small area of the areola, which healed with conservative dressing. The other complications, such as necrosis of the skin flap or areola, seroma, hematoma, or fat necrosis did not occur. CONCLUSIONS: Since one-stage nipple and breast reconstruction following ASM is an oncologically safe, cost-effective, and aesthetically satisfactory procedure, it is a good surgical option for early breast cancer patients.

Kimura disease is characterized by painless subcutaneous masses, usually in the head and neck area as well as serum/tissue eosinophilia and elevated serum IgE levels. Various treatment methods, such as surgical excision, corticosteroids, and radiotherapy, have been suggested, but none of these are considered standard therapy due to high recurrence rates. Dupilumab is a human monoclonal antibody that binds to the alpha subunit of IL-4 receptor for IL-4 and IL-13 and inhibits T helper 2 (Th2) response, which plays an important role in the pathogenesis of allergic diseases, such as atopic dermatitis, asthma, and nasal polyps. Kimura disease has also been shown to increase CD4+Th2 cells and Th2 cytokines. We report a case of a 12-year-old boy who had subcutaneous neck and orbital masses of Kimura disease concurrent with allergic rhinitis, decreased lung function, and IgG subclass deficiency. The masses did not improve with omalizumab or immunomodulatory agents, but resolved with dupilumab. Considering potential side effects of steroids or immunosuppressant agents, dupilumab may be an option for initial treatment with Kimura diseases in children.

Increases of neutrophils and osteoclasts are pathological changes of periodontitis. RANKL is an osteoclast differentiation factor. The effect of periodontopathogen LPS on RANKL-expressing neutrophils has not been clarified yet. We evaluated numerical changes of RANKL-expressing neutrophils in air pouches of mice injected with LPSs of Fusobacterium nucleatum and Porphyromonas gingivalis. Mice with air pouches were assigned into saline (C)-, E. coli LPS- (Ec LPS)-, F. nucleatum LPS (Fn LPS)-, P. gingivalis LPS (Pg LPS)-, and Fn LPS and Pg LPS (Fn + Pg LPS)-injected groups. CD11b +Ly6G + neutrophils and CD11b +Ly6G+RANKL + neutrophils in blood and air pouch exudates were determined by flow cytometry. In blood, compared to the C group, the Fn LPS group showed increases of CD11b +Ly6G + neutrophils and CD11b +Ly6G +RANKL + neutrophils whereas the Pg LPS group showed no significant differences. These increases in the Fn LPS group were not different to those in the Ec LPS group. In exudates, Fn LPS and Pg LPS groups showed increases of CD11b +Ly6G + neutrophils and CD11b +Ly6G +RANKL + neutrophils compared to the C group. Increased levels in the Fn LPS group were not different to those in the Ec LPS group, but Pg LPS group was lower than those in the Ec LPS group. In blood and exudates, the Fn+ Pg LPS group showed no difference in levels of these neutrophils compared to the Ec LPS group. LPSs of F. nucleatum and P. gingivalis increased RANKL-expressing neutrophils although the degrees of increases were different. These suggest that periodontopathogen LPS can act as a stimulant to increase RANKL-expressing neutrophils.

Rarely, surgical clips can migrate into the biliary tract after laparoscopic cholecystectomy and work as a nidus for biliary stone formation. We report a case of the development of a common bile duct (CBD) stone induced by surgical clip in a 57-year-old man who underwent laparoscopic cholecystectomy 10 years ago. On computed tomography, a CBD stone with a metallic material was found, and endoscopic retrograde cholangiopancreatography (ERCP) revealed a CBD stone including a metallic clip. The stone was removed completely by ERCP, and the surgical clip was found along with the stone.

The stems of Oplopanax elatus (OE) have long been used to treat inflammatory disorders in herbal medicine, and in the previous investigation, OE was found to possess anti-inflammatory activity in lipopolysaccharide-treated macrophages, RAW 264.7 cell. OE reduces inducible nitric oxide (NO) synthase-induced NO production, and interferes with mitogen-activated protein kinase activation pathways. In the present study, the pharmacological action of the water extract of OE was examined to establish anti-arthritic action, using a rat model of adjuvant-induced arthritis (AIA). The water extract of OE administered orally inhibited AIA-induced arthritis at (100 – 300) mg/kg/day. The paw edema was significantly decreased, in combination with reduced production of pro-inflammatory cytokines. The action mechanism includes an inhibition of MAPKs/nuclear transcription factor-κB activation. These new findings strongly suggest that OE possesses anti-arthritic action, and may be used as a therapeutic agent in inflammation-related disorders, particularly in arthritic condition.

Bronchiolitis obliterans (BO) is a late onset complication of allogeneic hematopoietic stem cell transplantation (HSCT), and treatment outcome is dismal if it does not respond to immunosuppressive therapy. A 21-year-old male diagnosed with acute myeloid leukemia received an allogeneic HSCT from human leukocyte antigen- identical sibling donor. Twenty one months after transplantation, he developed progressive dyspnea and was diagnosed BO. Despite standard immunosuppressive therapy, the patient rapidly progressed to respiratory failure and Novalung(R) interventional lung-assist membrane ventilator was applied in the intensive care unit. Three months after the diagnosis of BO, the patient underwent bilateral lung transplantation (LT) and was eventually able to wean from the ventilator and the Novalung(R). Since the LT, the patient has been under a strict rehabilitation program in order to overcome a severe lower extremity weakness and muscle atrophy. Histologic findings of the explanted lungs confirmed the diagnosis of BO. Nine months after the LT, the patient showed no signs of rejection or infectious complications, but still required rehabilitation treatment. This is the first LT performed in a patient with BO after allogeneic HSCT in Korea. LT can be an effective therapy in terms of survival for patients with respiratory failure secondary to development of BO following HSCT.
