Background: Many institutes are interested in lung metastatectomy than before because of the improved long term survival, low mortality, and low morbidity after lung metastatectomy. However, prognostic factors affecting long term survival are controversial. We attempt to analyze the prognostic factors affecting retrospectively by comparing the results of lung metastasectomy. Material and Method: Between Jan. 1990 and Dec. 1997, 74 operations were taken in 63 patients with pulmonary metastases in various primary sites. We analyzed the postoperative long term survival according to sex, cell type, laterality, disease free interval(DFI), operation, the number of metastases, and the size of the largest metastasis. Result: There were 27 male and 36 female patients. Sex did not appeared to affect survival time(p=0.849). The primary tumor was carcinoma in 32, sarcoma in 28, and others in 3. Cell type, considering carcinoma and sarcoma, did not relate to survival time(p=0.071). DFI had no influence on the outcome(p=0.902). The type of operative procedure had no influence on the outcome(p=0.556). The laterality of metastases, 47 unilateral(74.6%) and 16 bilateral(25.4%), had no influence on the outcome(p=0.843). The number of metastases excised(one, two or three, four or more) did not appear to affect survival(p=0.263). The size of largest metastasis(<=10mm, 11mm-30mm, and >30mm) did not appear to affect survival(p=0.751). Previous factors were evaluated in both the carcinoma and sarcoma patients respectively. DFI was the only significant prognostic factor in metastatic lung sarcoma(p=0.0026). Conclusion: Survival was not related to sex, cell type, laterality, DFI, operative procedure, number of metastases, nor the size of the largest metastasis. DFI was related to the survival time in sarcoma group but further study is needed.

The purpose of this study is to investigate the relationship between the development of laterality and bilateral motor abilities measured with respect to various rhythm movements in upper extremity of mentally retared children. The development of laterality was measured by a survey of dominace-hand. The bilateral motor abilities were assessed by means of a tentative rhythm beat test of hands. One hundred sixty eighty subjects with special education needs shose age ranged from 7 to 18 years old were used for an experimental group. Fity nine normal children whose age ranged from 3 to 6 years old were also chosen as a control group. The major findings were a follows: 1. The development of lateral dominace-hand in mentally retared children differed from that of normal subjects with as increase in chronological age; the degree of the attainment of lateral dominance - hand was 75 percest of the mean level of the normal children. Though normal children establish a dominance - hand by ths age of years old, meatally retarded children are likely to show 57 percent of normal development at the age of 7 through 9 years old and 65 percent of normal development at the age of 16 through 18 years old. 2. A greater delay in mentally retarded was found through a rhythm test which was development to assess bilateral motor abilities in upper extremity. A closser relationship betwin chronological age and the development of bilateral motor abilities in mentally retared children was found. 3. In view of these findings, it was indicated that bilateral motor abilities of the retarded and non-retarded children were significantly correlated to the acqusition of dominance-hand.

본 연구는 상담심리학의 성격특성이론에 근거하여 좌 우뇌의 신경학적 비대칭성 및 두뇌 각 영역에서의 활성뇌파와 성격의 요인별 특성과의 관련성을 EEG측정을 통해 알아보고자 하였다. 이에 96명의 대학생들을 대상으로 8채널 EEG 장비를 이용하여 뇌파를 측정한 후 컴퓨터로 분석한 자료와 성격 5요인 질문지를 사용하여 조사한 자료를 통계 분석하였다. 그 결과 전전두엽의 쎄타파 좌 우뇌비대칭이 클수록 성격요인 중 신경증이 높은 것으로 나타났고, 각 두뇌영역별로는 전전두엽좌측의 쎄타파 활성이 클수록 신경증은 높고, 성실성은 낮아지는 것으로 나타났으며, 전두엽좌측의 베타파 활성이 클수록 외향성과 개방성이 낮아지는 것으로 나타났다. 이러한 연구결과는 두뇌영역별 특정뇌파리듬의 활성이 개인의 성격 및 심리적 특성에 유의미한 관련이 있음을 알 수 있게 한다. 기존의 연구들 대부분이 주로 알파파, 베타파 영역에서 성격과의 관련성에 대해 언급했던 것과 달리, 본 연구결과는 세타파가 성격특성과 관련이 있을 수 있음을 시사한다. 이러한 연구 결과를 토대로 두뇌관련 상담전략과 후속연구에 대해 제언하였다.

Background: The common causes of lower back pain with or without leg pain includes disk disease and spinal stenosis. A definitive diagnosis is usually made by means of magnetic resonance imaging (MRI), but treatment is often difficult because the MRI findings are not consistent with the symptoms of the patient in many cases. The objective of this study was to observe the correlation between the patterns of epidurography performed in patients having lower back pain with or without leg pain and the position or severity of the pain as subjectively described by the patients. Methods: The subjects of this study were 69 outpatients with lower back pain with or without leg pain who visited our clinic and complained of predominant pain on one side. We performed caudal epidural block using an image intensifier. A mixture of the therapeutic drug and the contrast agent (10 ml) was injected to observe the contrast flow pattern. The patients who complained of predominant pain on one side were divided into the left side group and the right side group. A judgment of inconsistency was made if the contrast agent flowed to the side of the pain, while a judgment of consistency was made if the contrast agent flowed to the opposite side of the pain. The degree of the drug distribution was evaluated by counting the number of cells to which the contrast agent's flowed for evaluating the correlation between the contrasted cell and the severity of pain (one group ${\leq}$ VAS 7, the other group ${\geq}$ VAS 8) the degree of the contrast agent's contrast was evaluated by dividing and counting an image into 15 cells (the left, right, and middle sections at each level of L4, L5, S1, S2, and S3). Results: Thirty out of the 69 patients who had laterality in pain, that is, those who complained of predominant pain on one side, showed that the laterality of the pain and the contrast agent flow was consistent, while 39 patients showed that the laterality was inconsistent (P: 0.137). The evaluation of the correlation between the pain and the contrast agent flow showed that the mean number of contrasted cells was $9.0{\pm}2.2$ for the 46 patients in the group with a VAS of 7 or lower and $6.5{\pm}2.0$ for the 23 patients in the group with a VAS of 8 or higher, indicating that the former group showed a significantly greater number of contrasted cells (P < 0.001). Conclusions: This study, conducted with patients having lower back pain with or without leg pain, showed that the contrast flow pattern of caudal epidurography had a significant correlation with the severity of the pain but not with the laterality of the pain.

Background: The aim of this epidemiological study was to establish the laterality of breast cancer (BC) and its association with size, receptor status of the primary tumor and bone metastasis (BM) in a local population. Materials and Methods: This retrospective study included cases of BC from Jan-2009 to Dec-2011 who were referred for metastatic work up or follow up survey with Technetium-99m MDP bone scan (BS) to the Nuclear Medicine Department of Karachi Institute of Radiotherapy and Nuclear Medicine (KIRAN). A total of 384 patients out of 521 were included and all reviewed for age, primary tumor size (PTS), laterality, receptor status like estrogen receptor (ER) progesterone receptor (PR) and Her-2-Neu receptor, presence or absence of BM with sites of involvement and time interval between diagnosis of BC and appearance of BM. Results: The left to right sided BC proportion was significantly higher than unity (59%:41%; p<0.001). The right sided BC was observed in younger age group (46:52 years; p<0.0001) and with a smaller PTS than the left sided (3.43:4.15 cm; p<0.0001). The patients with BM had relatively higher negative receptor status with a significant predominance of right sided BC. The overall incidence of BM on BS was 28% and relatively higher in right than left breast (33%:24% p=0.068). The average number of BM sites was also significantly greater for the right side (6:4, P<0.0001). The % cumulative risk of BM in right breast was noted at significantly smaller PTS than left side with log rank value of 5.579; p<0.05. The Kaplan Meier survival plot for event free survival of BM in left sided BC was significantly higher than for the right side (log rank value=4.155, p<0.05), with an earlier appearance of BM in right BC. Conclusions: 1) A left sided predominance of BC was seen in local population; 2) right sided BC had a more aggressive behavior with extensive and earlier appearance of BM at relatively younger age, smaller PTS and receptor (s) negativity.
