Metastasis to the thyroid gland is usually considered uncommon. The most frequent sites of the primary tumor include the kidney, breast and lung. Its presence often indicates poor prognosis. Metastases represent the advanced stage of the tumors and fine needle aspiration cytology is and important way of diagnosis in thyroid metastasis. we experienced a case of Metastatic Small cell Lung Carcinoma to the Thyroid Gland. A 58-year-old man with Graves' disease diagnosed pulmonary nodule in the left upper lung field on his chest X-ray film. The patient's thyroid gland was diffusely swollen, and elastic to hard. A thyroid ultrasonography showed 1cm sized hypodense nodule on the left thyroid gland. The patient underwent a ultrasonography guided fine needle aspiration cytology of the mass. Cytological diagnosis was a metastatic small cell carcinoma. Then Chemotherapy was administered to the patient. The authors report this rare case of metastatic small cell lung carcinoma to the thyroid with literature review.

An instrument for measuring cone penetration using the strain gage system was devised. The soil hardness of given soils under different conditions can be measured and compared by using this instrument. The soil hardness is a very useful index for making decisions in various aspects of the field and laboratory use; the workability of the agricultural machinery on the given field, and the uniformity of soil hardness of the stuffed soil in the soil bin which is tilled repeatedly. The performance of this newly devised cone penetrometer was compared with the conventional one through the field test. The summarized results are as follows; 1. In case of KM-1 type cone penetrometer, the newly devised one, the relation between the cone index and the strain indicated are as follows, Ci=0.026642ε₁-0.4173 when base area is 3.23㎠ Ci=0.013342ε₂ when base area is 6.45㎠ 2. The KM-1 type cone penetrometer is more convenient than conventional one in view of its accuracy and its adaptability of the self recording system. 3. Cone index increases gradually as penetrating depth into the soil is increased. Its maximum value appeared at the depth of about 20cm and then the cone index decreases until the cone reaches the depth of 40cm. It is assumed that such increase of cone index is caused by the existence of plow pan in paddy fields. 4. When cone penetrometers are manually penetrated into the soil deeper than 20cm from ground surface, its found to be difficult to carry out measuring operations due to high soil resistance to penetration. So, in order to use cone penetrometers below the depth more than 20cm, some equipment is necessary to maintain uniform penetrating speed of the cone. 5. Under the same soil conditions, the relation between Cik and Cic, cone indexes derived KM-1 type from conventional cone penetrometers respectively, was as follow;??

With the increasing use of pancreatic duct (PD) stents after endoscopic papillectomy (EP), complications such as proximal migration of the stent have become increasingly prevalent. A PD stent that migrates within a nondilated PD may be difficult to remove endoscopically. We performed endoscopic retrieval of proximally migrated PD stents after EP in 5 patients. Endoscopic retrieval was performed immediately after EP in one patient, the next day in 3 patients, and 2 weeks later in one patient. Wire-guided endoscopic retrieval was attempted in 4 patients, and the migrated stents were removed successfully in these 4 patients. No signifi cant procedure-related complications occurred, other than mild pancreatitis in a single patient. In one patient, endoscopic retrieval performed immediately after EP failed when using the conventional method, and the migrated stent was removed using a minisnare without a guidewire the next day; this patient developed severe pancreatitis. Wire-guided endoscopic snare retrieval seems to be a safe and effective method for removing proximally migrated PD stents after EP. (Gut Liver 2011;5:532-535)

Background: Coinfections with multiple nontuberculous mycobacterial (NTM) species have not been widely studied. We aimed to evaluate the clinical characteristics and treatment outcomes in patients with NTM-pulmonary disease (PD) caused by coinfection with multiple NTM species. Methods: We retrospectively reviewed patients with NTM-PD at a tertiary referral hospital in Korea between March 2012 and December 2018. Coinfection was defined as two or more species of NTM pathogens isolated from the same respiratory specimen or different specimens within three months. Results: Among 1,009 patients with NTM-PD, 147 (14.6%) NTM coinfections were observed (average age 64.7 years, 69.4% women). NTM species were identified more frequently (median 6 vs. 3 times, P < 0.001) in the coinfection group than in the single species group, and follow-up duration was also longer in the coinfection group (median 44.9 vs. 27.1 months, P < 0.001). Mycobacterium avium complex (MAC) and M. abscessus and M. massiliense (MAB) were the dominant combinations (n = 71, 48.3%). For patients treated for over six months in the MAC plus MAB group (n = 31), sputum culture conversion and microbiological cure were achieved in 67.7% and 41.9% of patients, respectively. We divided the MAC plus MAB coinfection group into three subgroups according to the target mycobacteria; however, no statistical differences were found in the treatment outcomes. Conclusion: In NTM-PD cases, a significant number of multiple NTM species coinfections occurred. Proper identification of all cultured NTM species through follow-up is necessary to detect multispecies coinfections. Further research is needed to understand the nature of NTM-PD in such cases.

Effect of Cyclosporine on Circulating Interleukin-10 and Interleukin-12 in Pateints with Severe, Refractory Rheumatoid Arthritis

Background : To investigate the effect of cyclosporine on interleukin-10 (IL-10) and interleukin-12 (IL-12) in patients with rheumatoid arthrtis (RA) Methods : A 10-week randomized, double blind, placebo-control study of cyclosporine RA who had residual inflammation and isability despite partial reponses to prior maximal tolerated dose of methotrexate (<15 mg/week) and low dose prednisone (<10 mg/day). The clinical and laboratory variables, and circulating leves IL-10 and IL-12 measered by enzymelinked immunosorbent method, were compared between patients (cyclosporine group) treated with cycloporine plus methotreaxte and those (placebo group) treated with placebo plus methotrexate at the entry and 16 weeks of the study. Results : On the 16 weeks into the clinical trial, the cyclosporine group (n=17), compared with the placebo group (n=17), had higher degree of decreases in tender joints, patients global assessment, patients self assessed disability, C-reactive protein as well as having more patients with over 20% improvement. The comparison of the circulating IL-10 and IL-12 at the entry and 16 weeks of the study showed significant decreases of IL-12(median-313 versrs -14 pg/ml, p=0.002) and a significant increase of IL-10 (median 55 versus-12 pg/ml, p <0.001) in the cyclosporine group compared with the placebo group. The degree of IL-10 increases strongly correlated with the degree of IL-12 decreases in the cyclosporine group (r=0.572, p=0.016). Among the cyclosporine group, the improved patients (n 10), compared to the non-improved patients (n=7), had higher rate of increase in the circulating IL-10 (median 172.0 versus 85.2%, p=0.01). The rate of increase of IL-10 strongly correlated with the rate of improvement of joint scores (r=0.718, p=0.001) after administration of cyclosporine. Conclusion : Our results suggest that the therapeuic effect of cyclosporine is achieved by correcting Th1/Th2 imbalance (a shift Th1 type to Th2 type), which may be in the pathogenesis of RA, and circulating IL-10 is useful to assess the clinical improvements in patients with RA after administration of cyclosporine.

Ro60 Inhibits Colonic Inflammation and Fibrosis in a Mouse Model of Dextran Sulfate Sodium-Induced Colitis

Kim, Se-Young,Park, Min-Jung,Kwon, Jeong-Eun,Choi, Si-Young,Seo, Hyeon-Beom,Jung, Kyung Ah,Choi, Jeong-Won,Baek, Jin-Ah,Lee, Han Hee,Lee, Bo-In,Park, Sung-Hwan,Cho, Mi-La Elsevier 2018 IMMUNOLOGY LETTERS Vol.201 No.-

<P><B>Abstract</B></P> <P>Inflammatory bowel disease (IBD) is caused by chronic inflammation of the gastrointestinal tract. The pathogenesis of IBD remains unclear. The inflammation is associated with activation of T helper (Th) lymphocytes and chronic production of inflammatory cytokines. Ro60 suppresses the expression of tumor necrosis factor α, interleukin (IL)-6, and interferon α by inhibiting Alu transcription; control of Ro60 mRNA expression may thus be therapeutically useful. However, few studies have evaluated the anti-inflammatory activity of Ro60. The Ro60 level is decreased in IBD patients; we thus hypothesized that Ro60 was involved in the development of this autoimmune disease. We subjected mice with dextran sodium sulfate (DSS)-induced colitis to gene therapy using a vector that overexpressed Ro60 threefold. We scored IBD progression by repeatedly weighing the mice. Ro60 ameliorated colitis severity and reduced the levels of tumor necrosis factor α, IL-6, IL-17, IL-8, and vascular endothelial growth factor. Ro60 overexpression decreased the levels of α-smooth muscle actin (a marker of activated myofibroblasts) and type I collagen. The anti-inflammatory and anti-fibrotic activities of Ro60 ameliorated the severity of DSS-induced colitis in mice by repressing inflammation, fibrosis, angiogenesis, and the production of reactive oxygen species.</P> <P><B>Highlights</B></P> <P> <UL> <LI> Overexpression of Ro60 delivered using recombinant DNA ameliorates DSS induced colitis severity. </LI> <LI> Ro60 reduces the levels of IL-6 and TNF-α proinflammatory cytokines in vitro and in vivo. </LI> <LI> Ro60 inhibits the expression of markers of oxidative stress, fibrosis and cell death in colonic tissue. </LI> </UL> </P>
