Cutaneous metastases from follicular thyroid carcinoma are extremely rare. A 59-year-old woman presented with a 1 month history of a slowly enlarging scalp nodule. Ten years earlier, the patient had been received total thyroidectomy for anterior neck mass, and diagnosed as poorly differentiated follicular thyroid carcinoma. The patient had developed pulmonary metastases 4 years after the initial surgery and concurrent chemotherapy. A biopsy from the scalp nodule showed an intradermal tumor composed of mostly thyroid follicular structures with colloid material. The tumor cells were monomorphic with scant pale cytoplasm and uniform nuclei, and stained positive for thyroid transcription factor-1 and thyroglobulin. We report a cutaneous metastasis from the follicular thyroid carcinoma as a rare case.

BACKGROUND: Severe acute lung injury(ALI), also known as the adult respiratory distress syndrome(ARDS), is a heterogenous nature of dynamic and explosive clinical synrome that exacts a mortality of approximately 50%. Endotoxin(ETX) is an abundant component of the outer membrane of gram-negative bacteria capable of inducing severe lung injury in gram-negative sepsis and gram-negative bacterial pneumonia, which are among the most common predisposing causes of ARDS. The influx of PMNs into airway tissue is a pathological hallmark of LPS-induced lung injury. And th3re is a substantial evidence suggesting that cytokines are important mediators of lung injury in gram-negative sepsis. However, the kinetics of phagocytes and cytokines by an exact time sequence and their respective pathogenic importance remain to be elucidated. This study was performed to investigate the role of phagocytes and proinflammatory cytokines in ETX-induced ALl through a time course of changes in the concentration of protein, TNFa and IL-6, and counts of total and its differential cells in BALF. The consecutive histologic findings were also evaluated. METHOD: The experimental animals, healthy male Sprague-Dawley, weighted 200+/-50g, were divided into controland ALI-group. ALI was induced by an intravenous administration of ETX, 5mg/kg. Above mentioned all parameters were examined at 0(control), 3, 6, 24, 72 h after administration of ETX. TNFa and IL-6 conc. in BALE were measured by a bioassay. RESULTS: The protein concentration and total leukocyte count(TC) in BALF was significantly increased at 3h compared to controls(p<0.05). The protein conc. was significantly elavated during observation period, but TC was significantly decreased at 72h(p<0.05 vs. 24h). There was a close relationship between TC and protein cone. in BALF(r = 0.65, p <0.001). The PMN and monocyte count was well correlated with TC in BALF, and the correlation of PMN(r=0.97, p<0.001) appeared to be more meaningful than that of monoeyte(r = 0.61, p<0.001). There was also a significant correlation between protein cone. and PMN or monocyte count in BALF(PMN vs. monocyte r = 0.55, p<0.005 vs. r = 0.64, p<0.001). The count of monocyte was significantly elavated during observation period though a meaningful reduction of PMN count in BALF at 72h, this observation suggested that monocyte may, at least, partipate in the process of lung injury steadly. In this sudy, there was no relationship between IL-6 and TNFt conc., and TNFa but not IL-6 was correlated with TC(r 0.61, p <0.05) and monocyte(r = 0.67, p<0.05) in BALF only at 3, 6h after ETX introduced. In particular, the IL-6 cone. increased earlier and rapidly peaked than TNFz cone. in BALF. In histologic findings, the cell counts of lung slices were increased from 3 to 72h(p<0.001 vs. NC). Alveolar wallthickness was increased from 6 to 24h(p<0.001 vs. NC). There was a significant correlation between the cell counts of lung slices and alveolar wall-thickness(r= 0.61, p<0.001). This result suggested that the cellular infiltrations might be followed by the alterations of interstitium, and the edematous change of alveolar wall might be most rapidly recovered to its normal condition in the process of repair. CONCLUSION: We concluded that although the role of PMIN is partly certain in ETX-induced ALI, it is somewhat inadequate to its known major impact on ALL Alveolar macrophage and/or non-immune cells such as pulmonary endothelial or epithelial cells, may be more importantly contributed to the initiation and perpetual progression of ETX-induced ALI. The IL-6 in ETX-induced ALI was independent to TNFa, measured by a bioassay in BALF. The early rise in IL-6 in BALF implies multiple origins of the IL-6.

Various benign and malignant conditions can cause biliary obstruction. We present a rare case of obstructive jaundice due to the compression of the common hepatic duct by the anteriorly overriding right hepatic artery. This case was also associated with the absence of the lateral segment of the left hepatic lobe. The patient was a 39 year-old housewife with a 4-day history of jaundice and occasional febrile sensation. An abdominal computed tomography showed absence of the lateral segment of the left hepatic lobe and a percutaneous transhepatic cholangiography showed a band-like filling defect of 2 mm width at the level of the upper common hepatic duct. The anteriorly overriding right hepatic artery compressing the common hepatic duct and the absence of the lateral segment of the left hepatic lobe were confirmed by operation.

BACKGROUND: Forkhead box P3 (FOXP3) is an important marker of regulatory T cells. FOXP3 polymorphisms are associated with autoimmune diseases, cancers, and allograft outcomes. We examined whether single nucleotide polymorphisms (SNPs) at the FOXP3 locus are associated with clinical outcomes after allogenic hematopoietic stem cell transplantation (HSCT). METHODS: Five FOXP3 SNPs (rs5902434, rs3761549, rs3761548, rs2232365, and rs2280883) were analyzed by PCR-sequencing of 172 DNA samples from allogenic HSCT patients. We examined the relationship between each SNP and the occurrence of graft-versus-host disease (GVHD), post-HSCT infection, relapse, and patient survival. RESULTS: Patients with acute GVHD (grades II-IV) showed higher frequencies of the rs3761549 T/T genotype, rs5902434 ATT/ATT genotype, and rs2232365 G/G genotype than did patients without acute GVHD (P=0.017, odds ratio [OR]=5.3; P=0.031, OR=2.4; and P=0.023, OR=2.6, respectively). Multivariate analysis showed that the TT genotype of rs3761549 was an independent risk factor for occurrence of acute GVHD (P=0.032, hazard ratio=5.6). In contrast, the genotype frequencies of rs3761549 T/T, rs5902434 ATT/ATT, and rs2232365 G/G were lower in patients with post-HSCT infection than in patients without infection (P=0.026, P=0.046, and P=0.031, respectively). CONCLUSIONS: rs3761549, rs5902434, and rs2232365 are associated with an increased risk of acute GVHD and decreased risk of post-HSCT infection.

OBJECTIVE: To explore the association of the estrogen receptor dinucleotide repeat polymorphism with the risk of endometriosis. DESIGN: Case-control study. METHODS: One hundred fifty-one women with surgically or histologically diagnosed endometriosis of stages I-IV (ASRM, 1997) were recruited, and 137 patients with no evidence of endometriosis by laparoscopy or laparotomy served as control. Dinucleotide repeat polymorphism of the estrogen receptor gene was assessed by fluorescent PCR with gene scan analysis. Allele frequencies of dinucleotide repeat polymorphism of the estrogen receptor gene were evaluated. RESULTS: Fifteen alleles of the estrogen receptor dinucleotide repeat polymorphism were found in subjects: from 12 repeats to 27 repeats except 26 repeats. There was no statistically significant difference in the allele distribution of dinucleotide repeat polymorphism between patients with endometriosis and controls. However, patients with stage I or II endometriosis (n=51) showed a higher incidence of alleles with fewer (TA)n repeats (12-15 repeats) compared with controls (67.6% vs 52.9%, p=0.010, odds ratio=1.860). CONCLUSION: These results suggest that dinucleotide repeat polymorphism of the estrogen receptor gene is associated with the risk of minimal or mild endometriosis in the Korean population.

PURPOSE:The purpose of this study was to assess the effect of long-term and differing frequency of on-line hemodiafiltration (OL-HDF) on changes in degree of hemoglobin, albumin level, serum small and middle molecules concentration in stable patients with undergoing high-flux hemodialysis (HF-HD). METHODS:Twenty five patients with more than 3 months of HF-HD were divided into two groups and followed for more than 36 months. Group 1 was treated once with OL-HDF and twice with HF-HD per week. Group 2 was treated three times with OL-HDF per week. Analysis was performed to compare hemoglobin, biochemical parameters, serum beta-microglobulin, leptin, alpha-microglobulin levels in both groups. RESULTS:There were significant improvements in hemoglobin and albumin level in group 2 compared to group 1. After receiving OL-HDF for a mean of 24 months, patients on both groups had the significantly reduced predialysis level of beta-microglobulin compared to baseline level. However, there is no significant difference in beta-microglobulin level between both groups. The predialysis level of leptin and alpha-microglobulin with relatively large molecular weight was not significantly reduced during observational period and was not significantly different between both groups. CONCLUSION:There were improvements in hemoglobin and albumin level according to the frequency of OL-HDF. The predialysis level of beta-microglobulin was significantly reduced after receiving even once with OL-HDF per week for long-term. Therefore, our study can suggest that there is no correlation between the frequency of OL-HDF and the predialysis level of beta-microglobulin.

BACKGROUND/AIMS:
Since patients with human papillomavirus (HPV)-associated head and neck squamous cell carcinoma (HNSCC) have favorable outcomes after treatment, treatment de-escalation for these patients is being actively investigated. However, not all HPV-positive HNSCCs are curable, and some patients have a poor prognosis. The purpose of this study was to identify poor prognostic factors in patients with HPV-positive HNSCC.
METHODS:
Patients who received a diagnosis of HNSCC and tested positive for HPV from 2000 to 2015 at a single hospital site (n = 152) were included in this retrospective analysis. HPV typing was conducted using the HPV DNA chip assay or liquid bead microarray system. Expression of p16 in the tumors was assessed by immunohistochemistry. To determine candidate factors associated with overall survival (OS), univariate and multivariable Cox regression analyses were performed.
RESULTS:
A total of 152 patients with HPV-positive HNSCC were included in this study; 82.2% were male, 43.4% were current or former smokers, and 84.2% had oropharyngeal cancer. By univariate analysis, old age, performance status ≥ 1, non-oropharyngeal location, advanced T classification (T3–4), and HPV genotype 18 were significantly associated with poor OS. By multivariable analysis, performance status ≥ 1 and non-oropharyngeal location were independently associated with shorter OS (hazard ratio [HR], 4.36, p = 0.015; HR, 11.83, p = 0.002, respectively). Furthermore, HPV genotype 18 positivity was also an independent poor prognostic factor of OS (HR, 10.87, p < 0.001).
CONCLUSIONS
Non-oropharyngeal cancer, poor performance status, and HPV genotype 18 were independent poor prognostic factors in patients with HPV-positive HNSCC. Patients with these risk factors might not be candidates for de-escalation treatment.

PURPOSE: Childhood asthma has a considerable social impact and economic burden, especially in severe asthma. This study aimed to identify the proportion of childhood asthma severity and to evaluate associated factors for greater asthma severity. METHODS: This study was performed on 667 children aged 5–15 years with asthma from the nationwide 19 hospitals in the Korean childhood Asthma Study (KAS). Asthma was classified as mild intermittent, mild persistent, and moderate/severe persistent groups according to the National Asthma Education and Prevention Program recommendations. Multinomial logistic regression models were used to identify the associated factors for greater asthma severity. RESULTS: Mild persistent asthma was most prevalent (39.0%), followed by mild intermittent (37.6%), moderate persistent (22.8%), and severe persistent asthma (0.6%). Onset later than 6 years of age (adjusted odds ratio [aOR], 1.69 for mild persistent asthma; aOR, 1.92 for moderate/severe persistent asthma) tended to increase asthma severity. Exposure to environmental tobacco smoke (aOR, 1.53 for mild persistent asthma; aOR, 1.85 for moderate/severe persistent asthma), and current dog ownership with sensitization to dog dander (aOR, 5.86 for mild persistent asthma; aOR, 6.90 for moderate/severe persistent asthma) showed increasing trends with greater asthma severity. Lower maternal education levels (aOR, 2.32) and no usage of an air purifier in exposure to high levels of outdoor air pollution (aOR, 1.76) were associated with moderate/severe persistent asthma. CONCLUSIONS: Modification of identified environmental factors associated with greater asthma severity might help better control childhood asthma, thereby reducing the disease burden due to childhood asthma.
