Objectives : To investigate the clinical results of patients who were diagnosed with grade II spondylolithesis treated with Korean medicine of relaxative Chuna and Gangchuk herbal medicine. Methods : We reviewed medical records of four patients diagnosed with grade II spondylolisthesis. Each patient has taken intensive Korean medical admission treatment at Mokhuri Hospital. All patients received treatments of Gangchuk herbal medicine, relaxative Chuna and acupuncture during admission period. Before treatment and every after 7-day treatment the patient's pain and walking distance without pain were assessed. The zero minimum to ten maximum pain numeric rating scale(NRS) was used to determine the degree of pain. Results : Average admission duration was 23 days. All the patients' NRS decreased from median figure of 7.5[the minimum 7 to the highest 8] to median figure of 1[the minimum 0 to the highest 2]. Walking distance without pain increased from a median of 55 m[the minimum 20 m to the highest 100 m] to median of 165 m[the minimum 100 m to the highest 250 m]. Conclusions : Intensive conservative korean medical treatment was effective in reducing pain and functional improvement for grade II lumbar spondylosisthesis patients.

Neck mass has various etiologies, including inflammatory, congenital, neoplastic causes. The IgG4-related disease can cause symptoms in the head and neck areas with an inflammatory neck mass. It also shows clinical and pathological findings from inflammation caused by immune reactions, such as lymphocyte and plasma cell infiltration, storiform fibrosis, obliteration phlebitis, and invigorated serum IgG4 levels. The treatment guideline has not been established and still under debate, but systemic glucocorticoid seems to be effective in the most cases. In this brief report, a 48-year-old male patient presented with voice change for 3 weeks. Left side paramedian vocal fold palsy was observed in the flexible laryngoscopy. About 2.5×2.0×1.2cm size, heterogeneously enhanced neck mass with irregular margin encasing left carotid artery was noted on preoperative contrast enhanced neck CT scan, and it was suspicious of left carotid body tumor. The pathology shows IgG4-related disease rather than carotid body tumors. We report this case of IgG4-related disease, which can be misdiagnosed to carotid body tumors.

Background and Objectives: This study aimed to analyze the features of patients with papillary thyroid carcinoma (PTC) recurred as distant metastases (DM). Materials and Method: We retrospectively reviewed and analyzed clinical records of 63 patients who were treated for PTC recurred as DM between 2000 and 2006. Univariate and multivariate analyses of various clinical factors were performed. Results: Male patients were 12, and female patients were 51. The 5- and 10-year survival rates for PTC recurred as DM were 85% and 73%, respectively. Size of tumor, multiplicity of tumor, lateral neck node metastasis, and RAI ablation therapy with other treatments such as surgery were associated with survival rate (p < 0.005) in univariate analysis. The lateral neck node metastasis[p =0.039, hazard ratio=2.2(95% CI. 1.18~3.24)] and multiple organ DM[p =0.041, hazard ratio=2.18(95% CI. 1.03~2.89)] were related to the survival in multivariate analysis. Conclusion: PTC recurred as DM is uncommon (2.2%). The size of tumor, the multiplicity of tumor, lateral neck node metastasis and RAI ablation therapy with other treatments for DM were revealed as associated factors for the survival. Evaluation of DM should be considered in patients with PTC during long-term follow-up.

The pipe with a long-neck flange is widely used in power plants, chemical plants, and shipbuilding companies. New the pipe with a long-neck flange is manufactured by welding a thick flange to a pipe. But this long-neck flange pipe has some deflects in the welding region such as unfitting and local thermal fatigue, which weaken the strength around the neck of the flange. Moreover, after welding the flange, the contacting surfaces of the flange have to be machined flat. So, that is uneconomical. Therefore, to solve the above problems of the long-neck flange pipe, a new process, which has no defects around the flange neck, is required. In this study, three forming processes are suggested to get an enhanced long-neck flange. First suggested process consists of conical terming and flange forming. Second and third suggested processes consist of the bulging of a long pipe locally heated by induction coils and the flange forming. The differences between second and third suggestions are the thickness and local heating area of the pipe. That is, the thickness of the initial pipe of third suggestion is larger than that of the final product, and the local heating area is smaller than that of second suggestion. These three suggestions fur forming a long-neck flange are simulated by FE analyses with a commercial cede DEFORM 2D. Especially, the theoretical result of FE analysis on the first suggestion fur forming a long-neck flange is verified by the experiment with aluminum 6063 pipes. From the theoretical and experimental results, it is concluded that three suggested processes are very useful in order to manufacture the pipe with a long-neck flange without any deflects.

Background and Objectives : Narrow Band Imaging(NBI) is a novel optical technique that enhances the visualization of superficial microvascular architecture which is commonly increased and founded as an irregular shape in a neoplastic lesion. The aim of this study is the evaluation of the usefulness of NBI in the diagnosis of Head and Neck Cancer. Subjects and Methods : From December 2009 to January 2011, 31 consecutive patients who were diagnosed with head and neck malignancy were enrolled in this prospective study. The malignant findings of NBI were demarcated brownish lesion or increased intraepithelial papillary capillary loops(IPCLs) with or without irregularity. Results : There were 29 cases(93.5%) of well demarcated brownish lesion, 26 cases(83.9%) of increased IPCLs and 4 cases(12.9%) of satellite lesions. Diagnostic accuracy of endoscopic examination was increased from 83.9% to 93.5%, when NBI was applied to the conventional endoscopy(p>0.05). Conclusion : NBI is a powerful and safe screening test, which can be performed in out patient clinic without any supplementary procedure.

The performance of naked neck and normal chicken was evaluated with respect to growth, carcass, immune, biochemical and stress parameters under winter and summer seasons to assess the suitability of naked neck birds under high temperatures in the global scenario of climate change. The growth performance was significantly ($p{\leq}0.05$) higher in naked neck chicken in the summer season. The dressing percentage was significantly ($p{\leq}0.05$) higher in naked neck birds in both winter and summer season because of reduced plumage. The thigh, giblet and feather proportion significantly ($p{\leq}0.05$) varied between naked neck and normal chickens in summer season. The humeral immune response to sheep red blood cells (SRBC), Newcastle disease vaccine (NDV) and cutaneous basophil hypersensitivity (CBH) did not show any significant differences among the chicken groups. The protein and cholesterol concentration observed was within the normal ranges. The total cholesterol levels in plasma were significantly ($p{\leq}0.05$) lower in naked neck birds in both the seasons. H:L ratio was significantly ($p{\leq}0.05$) lower in summer season indicating less stress in naked neck chicken. Basophil and eosinophil concentration was significantly ($p{\leq}0.05$) higher in normal chicken in summer. The lipid peroxidation was higher in full feathered birds under summer stress. The enzyme glutathione reductase (GR) levels were significantly higher during the summer and varied significantly ($p{\leq}0.05$) between the normal and naked neck chicken in both seasons. The results indicated that the naked neck birds performed significantly better at high ambient temperatures with respect to growth, carcass and biochemical parameters. It was concluded that the ability of the naked neck chicken to adapt to high temperatures foresees a viable option for the biological mitigation of climate change.

Parathyroid cyst are rare lesion of the neck and superior mediastinum. They are classified as either functional or nonfunctional based on the presence or absence of hyperparathyroidism. They typically present as a palpable neck mass, or as an incidental finding during neck surgery. So, it must be included within the differential diagnosis of a neck lump. A 48-year old woman was admitted to our hospital for evaluation of left anterior neck mass. Physical finding showed soft, movable, non-tender mass on the lower left third of the neck. Laboratory findings revealed normal thyroid function and normal serum calcium level. On previous history, patient underwent two times sono-guided fine needle aspiration at local clinic, and about 10cc clear watery aspirate was noted. Computerized tomography findings showed non-enhancing hypodense cystic lesion on left thyroid area with tracheal deviation to right side. Preoperative diagnosis was thyroid cyst, and thyroidectomy was planed. Intra-operative finding showed huge cystic mass occupying the left thyroid area and smooth, shiny, semitransparent thin cyst wall was noted, which was loosely attached to the thyroid. The cyst was easily dissected free from the thyroid and surrounding tissues. After cyst removal, pathological study confirmed as a parathyroid cyst.
