Background: This study aimed to 1) assess the effect of total hip arthroplasty (THA) on coronal limb alignment, namely, the hip–knee–ankle angle (HKA), 2) identify factors that determine changes in the HKA, and 3) determine whether alignment changes influence the knee joint space width. Methods: We retrospectively evaluated 266 limbs of patients who underwent THA. Three types of prostheses with neck shaft angles (NSAs) of 132°, 135°, and 138° were used. Several radiographic parameters were measured in the preoperative and final radiographs (at least 5 years after THA). A paired t-test was used to confirm the effect of THA on HKA change. Multiple regression analysis was performed to identify radiographic parameters related to HKA changes following THA and changes in knee joint space width. Subgroup analyses were performed to reveal the effect of NSA change on the HKA change, and the proportion of total knee arthroplasty usage and changes in radiographic parameters between maintained joint space and narrowed joint space groups were compared. Results: The preoperative mean HKA was 1.4° varus and increased to 2.7° varus after THA. This change was related to changes in the NSA, lateral distal femoral angle, and femoral bowing angle. In particular, in the group with a decrease in NSA of > 5°, the preoperative mean HKA was largely changed from 1.4° varus to 4.6° varus after THA. The prostheses with NSA of 132° and 135° also led to greater varus HKA changes than those with an NSA of 138°. Narrowing of the medial knee joint space was related to changes in the varus direction of the HKA, decrease in NSA, increase in femoral offset. Conclusion: A large reduction in NSA can lead to considerable varus limb alignment after THA, which can have adverse effects on the medial compartment of the ipsilateral knee.

A Review of the Statistical Analysis used in Clinical Articles Published on Journal of Korean Neurosurgical Society

Kang, Wee-Chang The Korean Neurosurgical Society 2006 Journal of Korean neurosurgical society Vol.40 No.4

Statistical analyses used in clinical articles published on the Journal of Korean Neurosurgical Society were identified and appropriateness of statistical aspects in reporting results was assessed. Forty seven clinical articles were selected in this study, which were published from February, 2005 to February, 2006 on the journal. The frequency of statistical analysis was as follows : descriptive statistics only 24 [51.1%]. one type of statistical method 10 [21.3%], two or more methods 13 [27.6%]. An assessment of statistical aspects was performed in 24 clinical articles reporting inferential statistics. Ten articles [41.7%] did not adequately describe or reference all statistical methods used. There were six articles [25.0%] not reporting the confidence level used as the critical criteria of the statistical significance. In thirteen articles [54.2%] it seems more appropriate to implement multivariate analyses in addition to univariate analyses. We recommend that the journal readers should concentrate on improving their knowledge of basic statistics and statistical review for manuscripts submitted should be sought from professionals in the fields of biostatistics and epidemiology.

Objectives: Recently, angiogenesis has gained an increasing interest as a prognostic factor in breast cancer. In this study we aimed to assess the anti angiogenic effects of HAD, a botanical anticancer remedy which has been prescribed in Daejeon University Oriental Hospital in Korea, on patients with breast carcinoma by measuring the serum vascular endothelial growth factor (VEGF), basic fibroblast growth factor (b-FGF) and platelets levels. Methods: The study included 26 consecutive breast cancer patients (mean age$\pm$standard deviation: 47.5$\pm$8.7 years) with stage II to IV disease who were treated with HAD (mean duration $\pm$ standard deviation: 264.5$\pm$121.6 days). In addition to routine laboratory and staging procedures, serum VEGF, b-FGF levels and platelet counts were determined as antiangiogenic markers. The antiangiogenic effects of HAD were evaluated by analyzing the differences between the values of the antiangiogenic markers before and after the treatment with HAD. Results: Serum b-FGF concentrations were significantly reduced after the treatment with HAD (P=0.042). Serum VEGF concentrations were found to have a somewhat decreasing change, though the change was not statistically significant (P=0.229). Platelet counts had little changes (P=O.80). Conclusions: It is supposed that HAD has effects on decreasing the serum b-FGF levels related with the clinical outcome of breast cancer patients.

Purpose: Dipyridamole stress myocardial perfusion SPECT could predict prognosis, however, long-term follow-up showed change of hazard ratio in patients with suspected coronary artery disease. We investigated how long normal SPECT could predict the benign prognosis on the long-term follow-up. Materials and Methods: We followed up 1169 patients and divided these patients into groups in whom coronary angiography were performed and were not. Total cardiac event rate and hard event rate were predicted using clinical, angiographic and SPECT findings. Predictive values of normal and abnormal SPECT were examined using survival analysis with Mantel-Haenszel method, multivariate Cox proportional hazard model analysis and newly developed statistical method to test time-invariance of hazard rate and changing point of this rate. Results: Reversible perfusion decrease on myocardial perfusion SPECT predicted higher total cardiac event rate independently and further to angiographic findings. However, myocardial SPECT showed independent but not incremental prognostic values for hard event rate. Hazard ratio of normal perfusion SPECT was changed significantly (p<0.001) and the changing point of hazard rate was 4.4 years of follow up. However, the ratio of abnormal SPECT was not. Conclusion: Dipyridamole stress myocardial perfusion SPECT provided independent prognostic information in patients with known and suspected coronary artery disease. Normal perfusion SPECT predicted least event rate for 4.4 years. (Korean J Nucl Med 2000;34:39-54)

Kang, Ji-Young,Han, Jong-Min,Kim, Jun-Young,Jung, In-Chul,Kang, Wee-Chang,Oh, Young-Seon,Lee, Jin-Woo,Park, Yang-Chun The Society of Korean Medicine 2014 대한한의학회지 Vol.35 No.4

Objectives: To present the case of a 76-year-old man diagnosed with idiopathic interstitial pneumonias (IIPs) treated exclusively with traditional Korean medicine (TKM). Methods: The patient was treated with the revised Sasammaekmundong-tang (rSMT), acupuncture, and pharmacopuncture from September 2013 to May 2014 in our outpatient clinic. We prescribed rSMT three times a day for 4 months. Acupuncture and pharmacopuncture were performed twice a week for 9 months. To evaluate therapeutic efficacy, we recorded the patient's chief complaints at each visit, and pulmonary function test was performed at intervals of three months. Chest radiography and chest computed tomography were performed before and after treatment, respectively. Results: During the course of the treatment, dyspnea, cough, sputum, and overall pulmonary function improved. Conclusions: We suggest that traditional Korean medicine (TKM) for IIPs patients might be effective in the control of the main symptoms of IIPs and in the recovery of respiratory function.

Cleft lip, with or without cleft palate, is one of the most common congenital malformations in Korea. Improper management of the patients with cleft lip and/or palate may result in facial maldevelopment, speech disturbance, social maladjustment and psychological stress together with their parents. For the past 16 years, from 1978 through 1994, we have treated 1502 patients with cleft lip and/or palate in Catholic Medical Center. The medical records and laboratory data were reviewed in order to secure the information for the retrospective study but valuable data were available in 673 cases. The present paper deals with an analysis of them to report the statistical and basic clinical data of cleft lip and/or palate. The results were as follows; 1. The rate of the associated anomalies was 4.1% and congenital heart disease was the most frequent one. 2. The ratio of cleft lip, cleft lip with palate and cleft palate alone was 1.5 : 1.3 : 1.0. 3. The ratio of left, right and bilateral cleft lip was 2.3 : 1.4: 1.0 and that of cleft lip with palate was 1.5 : 1.0 : 1.01. 4. The incomplete cleft lip occurred 2.01 times more than complete cleft lip and complete cleft lip with palate occurred 2.95 times more than incomplete cleft lip with palate, and the ratio of complete, incomplete and submucose cleft palate was 2.5 : 8.0 : 1.0. 5. Male was affected 1.4 times more than female in cleft lip and 2.3 times in cleft lip with palate and female was affected 2.3 times more than male in cleft palate. 6. Most of the patients was operated between the age of 3 months to 1 year in cleft lip(62%) and between 1 to 2 years in cleft palate(50%), 7. Before 1990, the Tennison-Randall method was widely used but after that, the Millard methods( ⅠⅡ) were undergone predominantly in cleft lip repair and most of the patients with cleft palate (91%) was treated by push-back palatoplasty, except submucose type which was corrected by double reversing Z-palatoplasty. 8. Almost all the patients with cleft palate(95%) were treated by myringotomy due to the middle ear disease (serous otitis media)at the same time.

Status of Aircraft Bird Strikes at Airports in Korea

Wee-Haeng Hur,Jin-Han Kim,Hwa-Jung Kim,Sung-Hyun Kim,Seung-Gu Kang,Myounghai Kwak,Chang Hwan Bae,Sun-Nam Park 한국조류학회II 2015 한국조류학회지 Vol.22 No.1

This study was carried out to secure basic data for a plan to reduce bird strikes by analysing information on collisions and bird species. We received 63 unidentified bird strike samples―for example, feathers, blood and tissue―from 8 airports in Korea from August 2009 to December 2010. We considered a bird strike sample as a case of bird strike, and used information on bird species that was identified by using DNA COI segments from the samples. Information was used on collisions from reports of bird strikes from airports and additional information collected from websites of KAC. From the results, 15 bird strikes occurred in Jeju airport and 8 bird strikes occurred in Gimpo airport. The occurrence of bird strikes was related to the number of aircraft movements in airports. However, we could not confirm the major bird strike species in each airport and also could not find the trend of the relation between the size of aircraft and occurrence of bird strikes. More bird strikes occurred during landing than takeoffs and engines made up the highest proportion of bird strikes. Seasonally, the occurrence of bird strikes was higher in October, September, November and May than in other months. This trend seems related to the patterns of the seasonal migration of birds. The daily pattern of bird strikes was higher in the morning and at sunset than at other times, and nocturnal birds were also struck at night time. This trend seems related to the daily patterns of birds.
