  • Background: Prognostic value of prophylactic level VII nodal dissection in papillary thyroid carcinoma has been highlighted. Materials and Methods: A total of 27 patients with papillary thyroid carcinoma with N0 neck underwent total thyroidectomy with level VI and VII nodal dissection through same collar neck incision. Multicentricity, bilaterality, extrathyroidal extension, level VI and VII lymph nodes were studied as separate and independent prognostic factors for DFS at 24 months. Results: 21 females and 6 males with a mean age of 34.6 years old, tumor size was 5-24 mm. (mean 12.4 mm.), multicentricity in 11 patients 2-4 foci (mean 2.7), bilaterality in 8 patients and extrathyroidal extension in 8 patients. Dissected level VI LNs 2-8 (mean 5 LNs) and level VII LNs 1-4 (mean 1.9). Metastatic level VI LNs 0-3 (mean 1) and level VII LNs 0-2 (mean 0.5). Follow-up from 6-51 months (mean 25.6) with 7 patients showed recurrence (3 local and 4 distant). Cumulative DFS at 24 months was 87.8% and was significantly affected in relation to bilaterality (p-value <0.001), extrathyroidal extension (p-value <0.001), level VI positive ((p-value <0.001) and level VII positive ((p-value <0.001) LNs. No recurrences were detected during the follow-up period in the absence of level VI and level VII nodal involvement. Conclusions: Level VII prophylactic nodal dissection is an important and integral prognostic factor in papillary thyroid carcinoma. A larger multicenter study is crucial to reach a satisfactory conclusion about the necessity and safety of this approach.

  • Purpose: To study the safety of prophylactic level VII nodal dissection regarding hypoparathyroidism (temporary and permanent) and vocal cord dysfunction (temporary and permanent) and its impact on disease free survival. Materials and Methods: This prospective study concerned 63 patients with papillary thyroid carcinoma with N0 neck node involvement (clinically and radiologically) in the period from December 2009 to May 2013. All patients underwent total thyroidectomy and prophylactic central neck dissection including levels VI and VII lymph nodes in group A (31 patients) and level VI only in group B (32 patients). The thyroid gland, level VI and level VII lymph nodes were each examined histopathologically separately for tumor size, multicentricity, bilaterality, extrathyroidal extension, number of dissected LNs and metastatic LNs. Follow-up of both groups, regarding hypoparathyroidism, vocal cord dysfunction and DFS, ranged from 6-61 months. Results: The mean age was 34.8 and 34.3, female predominance in both groups with F: M 24:7 and 27:5 in groups A and B, respectively. Mean tumor size was 12.6 and 14.7mm. No statistical differences were found between both groups regarding age, sex, bilaterality, multicentricity or extrathyroidal extension. The mean no. of dissected level VI LNs was 5.06 and 4.72 and mean no. of metastatic level VI was 1 and 0.84 in groups A and B, respectively. The mean no. of dissected level VII LNs was 2.16 and mean no. of metastatic LNs was 0.48. Postoperatively temporary hypoparathyroidism was detected in 10 and 7 patients and permanent hypoparathyroidism in 2 and 3 patients; temporary vocal cord dysfunction was detected in 4 patients and one patient, and permanent vocal cord dysfunction in one and 2 patients in groups A and B, respectively. No significant statistical differences were noted between the 2 groups regarding hypoparathyroidism (P=0.535) or vocal cord dysfunction (P=0.956). The number of dissected LNs at level VI only significantly affected the occurrence of hypoparathyroidism (<0.001) and vocal cord dysfunction (<0.001).The DFS was significantly affected by bilaterality, multicentricity and extrathyroidal extension. Conclusions: Level VII nodal dissection is a safe procedure complementary to level VI nodal dissection with prophylactic central neck dissection for papillary thyroid carcinoma.

  • Purpose: Congenital factor VII (FVII) deficiency is a rare bleeding disorder and surgery can cause excessive bleeding due to an extrinsic pathway problem. It can be diagnosed by increased PT and decreased FVII level in coagulation test. Symptom varies according to the level of FVII, but it is essential to prevent intraoperative excessive bleeding. Methods: In this report, we described the orthognatic surgery experience in a mandibular prognathism patient with congenital FVII deficiency, in which recombinant activated factor VII (rFVIIa) was used to manage the bleeding. Rsults: We could get a successful result without any complication and there was minimal intraoperative bleeding. Conclusion: The orthognathic surgery could therefore be safely performed in patients with congenital factor VII deficiency using rFVIIa.

  • A congenital factor VII deficiency is a rare disorder with an estimated incidence in the western contries of one in 500,000. Because factor VII is important in initiation the coagulation cascade, a factor VII deficiency can result in significant bleeding with prolongation of the prothrombin time. We present a case of a factor VII deficiency with a subdural hematoma in an 18-year-old boy whose plasma activity of factor VII was ${\leq}10%$. Previously, he did not have any symptoms, such as hemarthrosis, easy bruising or bleeding after a minor trauma. He was administered fresh frozen plasma and a trephination was performed. His sister also had 51% lower level of factor VII.

  • A factor VII gene -401 G/A polymorphism was identified in a patient with a pulmonary embolism. The patient was a 71-year-old woman who presented with acute-onset dyspnea. A chest CT scan revealed a pulmonary embolism. Despite the administration of low-dose warfarin as anticoagulation therapy, there was an excessively prolonged prothrombin time (PT). The blood tests revealed lower factor VII activity than normal. Full factor VII gene sequencing revealed a G to A substitution at -401 in the promoter region. There were no other gene sequence anomalies. PCR-based analysis indicated lower factor VII gene expression in the patient than in a control subject. The data suggested the promoter polymorphism to be responsible for the lower transcription level. In conclusion, we encountered a case of Factor VII DNA polymorphism in a patient with a pulmonary embolism showing significantly reduced Factor VII activity.

  • 지난 회에서는 고층 주거 빌딩의 외피를 높이라는 주요 변수 및 이 변수의 함수를 통해 발생하는 파생적인 변수들을 통해 파라메트릭 모델로 구성해 나가는 과정을 살펴보았습니다. 이번 회에도 지난회와 같은 연장선상에서 디자인에 영향을 미치는 하나의 변수를 설정하고 이 변수를 통해 전체적인 디자인을 구성해 나가는 과정에 대하여 살펴볼까 합니다. 지난 회의 예와는 조금 다르게 이번 회의 예는 "변수화 된 모듈러"라는 비교적 친근한 컨셉에 더 가깝다고 할 수 있습니다. 저번 회의 고층 주거의 스킨은 다수의 레이어로 구성이 되었었고 각 레이어들이 해당 레이어 전역에 걸쳐 변수와 상관관계를 가지게 되며 이러한 상관관계가 각 레이어들별로 서로 다르게 정의 되므로 conceptual level에서의 변수와 물리적 형태의 상관관계가 눈에 쉽게 보이는 물리적인 모듈러로 구현된다기 보다는 그러한 conceptual level에서의 관계가 물리적 모듈러의 생성단계를 뛰어넘으며 결과적으로 눈에 보이는 모듈러의 생성을 하지 않았습니다. 이에 더해 개별의 레이어의 적층으로 인해 변수가 어떻게 디자인에 영향을 주는지 직관적으로 이해하기 힘들었을 수도 있을 것 같습니다. 그에 반해 이번 회에서 살펴볼 예는 파라메트릭 디자인이라고 사람들이 흔히 이야기 할 때의 전형에 조금 더 가깝다고 볼 수 있을 것 같습니다.

  • In order to study the effect of source and level of the commonly used dietary fats on growth and metabolism of rats fed on low protein diet (rice diet) the weaning white rats were fed on various different experimental diets (see tables 1 and 2) during 11 weeks. The observations were made as follows : 1. Growth: (see table 3 and figures 1-9) In all dietary fats, among the 3 levels, 5% fat level is the best. Especially, the perilla oil group was remarkably good. 10% and 20% fat levels impaired the growth, consequently the growth rates of both 10% and 20% fat level groups were worse than those of Basal group (no fat added). However, 10% and 20% fat levels did not impaired the growth of VII group (10% soy flour added) In 5% fat level, the growth was good in sequence of perilla oil, tallow, sesame oil, soy oil and lard. 2. Feed consumption: (see table 3) In 20% fat level, the feed consumption was lowered. Generally, the feed consumption rate was proportional to the growth rate. In feed efficiency, 5% fat level was the best. 3. Liver weight: (see table 4) In liver weight per 100 G body weight, 20% fat level was the largest. This may be due to the poor body growth and liver fat accumulation. 4. Liver nitrogen: (see table 4) Generally, lower fat level groups showed liver nitrogen. Liver nitrogen is low in the groups of 20% fat level. 5. Liver fat: (see table 4) Generally, higher fat level groups showed higher liver fat. 6. Serum cholesterol: (see table 5) Generally, higher fat level groups showed higher serum cholesterol. Lard, sesame oil, and tallow groups showed higher level and soy oil and perilla oil groups showed lower level. Especially, perilla oil group showed remarkably lower level and VII group (10% soy flour added) showed lower level than VI group (same fat but no soy flour added).

  • This study was carried out using rats weighing $40{\sim}50\;g$ which were devided into seven groups with various diet compositions emphasizing fat levels of perilla seed oil for the period of 41/2 weeks. The levels of fat in the diet were 5%, 10%, 15% and animals were fed ad libitum. The results are as follows : 1) Yellow pjgmentation of both neck and tail was clearly observed in groups fed 10% and 15% level perilla seed oil without vitamin I supplementation (IV and VII). 2) The growth rate in groups fed 15% level perilla seed oil was reduced as compared to that in groups fed 5% or 10% level perilla seed oil. 3) The mean hematocrit values of 15% level perilla seed oil groups tended to be lower than those of control group, tut the differences were not significant. 4) The serum vitamin I concentration showed different value in various groups, the values of control group were significantly higher than those of perilla seed oil groups-15% level with or without vitamin E supplementation (VI and VII) and 10% level without vitamin E supplementation (IV). According to the results, 10% level-perilla seed oil in the diet can be considered safe if vitamin E is not omitted from the vitamin mixture ana the group fed 15% fat with P/S ratio of 1 appeared to be safe during the experimental period. Finally the long-term studios have to be persued in many aspects by using perilla seed oil in the experimental diet. Because rats are known t4 be quite resistant to the experimental diets, comparative studies using various animal species have to he conducted.

  • New versions of ENDF/B and JEFF data libraries have been released during the past two years with significant updates in the neutron reaction sublibrary and the thermal neutron scattering sublibrary. In order to get a more comprehensive impression of the criticality quality of these two latest neutron data libraries, and to provide reference for the selection of the evaluated nuclear data libraries for the science and engineering applications of the Reactor Monte Carlo code RMC, the criticality benchmarking of the two latest neutron data libraries has been performed. RMC was employed as the computational tools, whose processing capability for the continuous representation ENDF/B-VIII.0 thermal neutron scattering laws was developed. The RMC criticality validation suite consisting of 116 benchmarks was established for the benchmarking work. The latest ACE format data libraries of the neutron reaction and the thermal neutron scattering laws for ENDF/B-VIII.0, ENDF/B-VII.1, and JEFF-3.3 were downloaded from the corresponding official sites. The ENDF/B-VII.0 data library was also employed to provide code-to-code validation for RMC. All the calculations for the four different data libraries were performed by using a parallel version of RMC, and all the calculated standard deviations are lower than 30pcm. Comprehensive analyses including the C/E values with uncertainties, the δk/σ values, and the metrics of χ2 and < |Δ| >, were conducted and presented. The calculated keff eigenvalues based on the four data libraries generally agree well with the benchmark evaluations for most cases. Among the 116 criticality benchmarks, the numbers of the calculated keff eigenvalues which agree with the benchmark evaluations within 3σ interval (with a confidence level of 99.6%) are 107, 109, 112, and 113 for ENDF/B-VII.0, ENDF/B-VII.1, ENDF/B-VIII.0 and JEFF-3.3, respectively. The present results indicate that the ENDF/B-VIII.0 neutron data library has a better performance on average.
