목적: 골스캔이 측두하악관절장애의 예후 예측에 유용한지 알려져 있지 않다. 이 연구의 목적은 편측성 측두하악관절장애 환자에서 예후 예측 인자로서 유용한 골스캔 소견은 무엇인지 알아보는 것이었다. 대상 및 방법 : 2005년 1월부터 2007년 7월에 걸쳐서 편측성 측두하악관절장애로 진단받고 치료 전 골스캔을 시행한 55명의 환자(남:여=9:46; 나이, $34.7{\pm}14.1$세)들을 대상으로 하였다. 양측의 측두하악관절과 두정골 영역에서 $13{\times}13$ 픽셀 크기의 정사각형 관심영역을 그려서 Tc-99m HDP섭취를 정량화하였다. 측두하악관절 섭취비는(측두하악관절 카운트 - 배후영역 카운트) / 배후영역 카운트로 계산하였고 이환된 측두하악관절에 대한 비대칭지표는 이환된 관절과 비이환된 관절 섭취비의 비로 정의하였다. 교합안정장치 시행 6개월 후 임상적 평가를 통해 호전군과 비호전군으로 나누고 골스캔 소견이 이러한 예후에 따라 어떻게 다른지 평가하였다. 결과: 46명의 환자가 호전되었고 9명의 환자는 증상의 호전이 관찰되지 않았다. 호전군과 비호전군간에 이환관절의 측두하악관절 섭취비, 반대편 정상관절의 측두하악관절 섭취비,그리고 비 대칭지표의 유의한 차이는 관찰되지 않았다(p>0.05). 그러나 소그룹 분석에서 이환 측두하악관절에 Tc-99m HDP의 섭취가 증가한 환자들에서는 비대칭지표에 의해 환자군이 구분되었다. 즉, 호전군의 비대칭지표가 비호전군에 비하여 유의하게 증가되어 있었다($1.32{\pm}0.35$ vs. $1.08{\pm}0.04$, p=0.023). 결론: 편측성 측두하악관절장애 환자에서 Tc-99m HDP 골스캔은 시각 분석에서 이환 관절의 섭취가 증가되어 있는 경우 교합안정장치 치료에 대한 예후를 예측할 수 있는 것으로 보인다.
Purpose: To assess the validity of individual and combined prognostic effects of severe bronchopulmonary dysplasia (BPD), brain injury, retinopathy of prematurity (ROP), and parenteral nutrition associated cholestasis(PNAC). Methods: We retrospectively analyzed the medical records of 80 extremely low birthweight (ELBW) infants admitted to the neonatal intensive care unit (NICU) of the Severance Children's Hospital, and who survived to a postmenstrual age of 36 weeks. We analyzed the relationship between 4 neonatal morbidities (severe BPD, severe brain injury, severe ROP, and severe PNAC) and poor outcome. Poor outcome indicated death after a postmenstrual age of 36 weeks or survival with neurosensory impairment (cerebral palsy, delayed development, hearing loss, or blindness) between 18 and 24 months of corrected age. Results: Each neonatal morbidity correlated with poor outcome on univariate analysis. Multiple logistic regression analysis revealed that the odds ratios (OR) were 4.9 (95% confidence interval [CI], 1.0-22.6; $P$=0.044) for severe BPD, 13.2 (3.0-57.3; $P$<.001) for severe brain injury, 5.3 (1.6-18.1; $P$=0.007) for severe ROP, and 3.4 (0.5-22.7; $P$=0.215) for severe PNAC. Severe BPD, brain injury, and ROP were significantly correlated with poor outcome, but not severe PNAC. By increasing the morbidity count, the rate of poor outcome was significantly increased (OR 5.2; 95% CI, 2.2-11.9; $P$<.001). In infants free of the above-mentioned morbidities, the rate of poor outcome was 9%, while the corresponding rates in infants with 1, 2, and more than 3 neonatal morbidities were 46%, 69%, and 100%, respectively. Conclusion: In ELBW infants 3 common neonatal mornidifies, severe BPD, brain injury and ROP, strongly predicts the risk of poor outcome.

Background: Methylation of tumor suppressor genes has been investigated in all kinds of cancer. Tumor specific epigenetic alterations can be used as a molecular markers of malignancy, which can lead to better diagnosis, prognosis and therapy. Therefore, the aim of this study was to evaluate the association between gene hypermethylation and expression of fragile histidine triad (FHIT), glutathione S-transferase P1 (GSTP1) and p16 genes and various clinicopathologic characteristics in primary non-small cell lung carcinomas (NSCLC). Materials and Methods: The study included 28 primary non-small cell lung carcinomas, where an additional 28 tissue samples taken from apparently normal safety margin surrounding the tumors served as controls. Methylation-specific polymerase chain reaction (MSP) was performed to analyze the methylation status of FHIT, GSTP1 and p16 while their mRNA expression levels were measured using a real-time PCR assay with SYBR Green I. Results: The methylation frequencies of the genes tested in NSCLC specimens were 53.6% for FHIT, 25% for GSTP1, and 0% for p16, and the risk of FHIT hypermethylation increased among patients with NSCLC by 2.88, while the risk of GSTP1 hypermethylation increased by 2.33. Hypermethylation of FHIT gene showed a highly significant correlation with pathologic stage (p<0.01) and a significant correlation with smoking habit and FHIT mRNA expression level (p<0.05). In contrast, no correlation was observed between the methylation of GSTP1 or p16 and smoking habit or any other parameter investigated (p>0.05). Conclusions: Results of the present study suggest that methylation of FHIT is a useful biomarker of biologically aggressive disease in patients with NSCLC. FHIT methylation may play a role in lung cancer later metastatic stages while GSTP1 methylation may rather play a role in the early pathogenesis.
Background: Inflammation is a critical component of tumor progression. Many cancers arise from sites of infection, chronic irritation, and inflammation. It is now becoming clear that the tumour microenvironment, which is largely orchestrated by inflammatory cells, is an essential participant in the neoplastic process, promoting proliferation, survival and migration. Platelets can release some growth factors such as platelet-derived growth factor, platelet factor 4, and thrombospondin. Such factors have been shown to promote hematogenous tumour spread, tumor cell adhesion and invasion, and angiogenesis and to play an important role in tumor progression. In this study, we aimed to investigate effects of the pretreatment neutrophil to lymphocyte ratio (NLR) and the platelet to lymphocyte ratio (PLR) on survival and response to chemoradiotherapy in patients with non-small-cell lung cancer (NSCLC). Materials and Methods: Ninety-four patients with non-metastatic NSCLC were included and separated into two groups according to median valuse of NLR and PLR (low:<3.44 or high:${\geq}3.44$ and low:<194 or high${\geq}194$, respectively). Results: Pretreatment high NLR and PLR were associated with significantly shorter disease-free and overall survival rates. Multivariate analysis revealed that the overall survival rates were significantly linked with PLR (OR: 1.87, CI: 1.20-2.91, p: 0.006) and response to chemoradiotherapy (OR: 1.80, CI: 1.14-2.81, p: 0.012) and the disease-free survival rates were significantly associated with NLR (OR: 1.81, CI: 1.16-2.82, p: 0.009) and response to chemoradiotherapy (OR: 2.30, CI: 1.45-3.66, p: 0.001). There was no significant difference between patients with high and low NLR in terms of response to chemoradiotherapy. Similarly, there was no significant influence of the PLR. Conclusions: Pretreatment NLR and PLR measurements can provide important prognostic results in patients with NSCLC and assessment of the two parameters together appears to better predict the prognosis in patients with NSCLC. The effect of inflammation, indicators of NLR and PLR, on survival seems independent of the response to chemoradiotherapy.
Purpose: Computed tomography (CT) is an accurate test for evaluating hemodynamically stable patients with blunt abdominal trauma. Until now, there have been few studies concentrating on the diagnostic and prognostic significance of the intravenous contrast extravasation (CE) site. We investigated the site of CE on abdominopelvic CT (APCT) and its effect on treating trauma patients and predicting the clinical outcome. Methods: The 50 patients admitted to our emergency department with blunt abdominal trauma showing CE on APCT from January 2004 to September 2006 were included in this study. Patients were prospectively collected, and medical records were reviewed and analyzed. The patients'clinical and lab findings, Focused Assessment with Sonography for Trauma (FAST) findings, CT findings were analyzed. CE sites were classified as intraperitoneal, retroperitoneal, and pelvic cavity and were correlated with post-treatment complications, mortality, and morbidity. Results: Of the 50 patients (mean age : $45{\pm}18years$, 29 males, 21 females) included in our study, 33 patients died (66%). There was no correlation between CE site and ICU or total hospitalization duration (p=0.553, p=0.523). During the first 24 hours of resuscitation, the pelvic cavity group required a mean of 20 units more of packed red blood cell (pRBC) transfusion compared to other groups (p=0.003). In the intraperitoneal group, more patients received operative invasive intervention - either laparotomy or embolization (p=0.025). The intraperitoneal group had the highest mortality, with 13 deaths (11/33, 39%), and the highest early mortality rate (10/13, 76%) in the first 24 hours (p=0.001). Conclusion: Intraperitoneal CE on the CT scan in cases of blunt abdominal trauma is regarded as an indication of a need for invasive intervention (either angiography or laparotomy) and of a higher mortality rate in the first 24 hours. A pelvic cavity CE rquires more aggressive transfusion with pRBC. However, the CT findings themselves showed no significant correlation with overall mortality, morbidity, or hospitalization.
Background: Thyroid cancer is a relatively rare neoplasm and its incidence varies geographically and ethnically around the world. Thyroid cancer is the most common endocrine malignancy, but it has a wide spectrum of biologic behavior, histologic appearance, and management. Purpose: The purpose of the study was to analyse and evaluate all aspects of the clinical consideration in thyroid cancer. Method: Between 1986 and 1995, a retrospective analysis of 77 thyrod cancer patients admitted at the Department of Surgery, Hangang Sacred Heart Hospital, Hallym University was made to assess clinical entities. Result: By the pathological classification, the papillary carcinoma was the most common type(83.1%). Male to female ratio was 1 : 5.4 and most prevalent age group was noted from fourth decade to fifth decade(46.8%). The most common duration of illness between the appearance of the symptoms and the treatment was below 6 months(44.2%), and the most common symptom was the palpable mass at the anterior portion of the neck(96.1%). Most cases of the thyroid cancer were appeared as cold nodule in the $^{99m}$Tc-thyroid scan(95.7%). In the site of tumor location, the right and left lobe was distributed similarly. In the extent of tumor, incidence of intrathyroidal location was 41.6%, and that of the metastasis to the cervical lymph nodes was 44.2% and that of the direct capsular invasion was 27.3%, and incidence of both involved case was 13%. Surgical procedures were total thyroidectomy alone in 27 cases(35.1%) or with modified neck dissection in 6 cases(7.8%), or with radical neck dissection in 2 cases (2.6%), near total thyroidectomy alone in 22 cases(28.6%), ipsilateral lobectomy with isthmectomy alone in 12 cases(15.6%) or with modified neck dissection in 1 case(1.3%), and biopsy only in 7 cases(9.1%). The most common postoperative complications were transient hypoparathyroidism(5.2%) and transient unilateral recurrent laryngeal nerve paralysis(5.2%). Conclusion: The major problem of management of thyroid cancer include a wide spectrum of clinical behaviour of this tumor entity, the lack of reliable prognostic factors and lack of an objective assessment of the various treatment modalities. But because of showing the favorable prognosis for most thyroid cancer, appropriate and aggressive management should be recommended.
Objectives: This study aimed to examine the characteristics of patients according to their nutritional status as assessed by five nutritional screening tools: Patient-Generated Subjective Global Assessment (PG-SGA), NUTRISCORE, Nutritional Risk Index (NRI), Prognostic Nutritional Index (PNI), and Controlling Nutritional Status (CONUT) and to compare the agreement, sensitivity, and specificity of these tools. Methods: A total of 952 gastric cancer patients who underwent gastrectomy and chemotherapy from January 2009 to December 2012 at the Samsung Medical Center were included. We categorized patients into malnourished and normal according to the five nutritional screening tools 1 month after surgery and compared their characteristics. We also calculated the Spearman partial correlation, Cohen's Kappa coefficient, the area under the curve (AUC), sensitivity, and specificity of each pair of screening tools. Results: We observed 86.24% malnutrition based on the PG-SGA and 85.82% based on the NUTRISCORE among gastric cancer patients in our study. When we applied NRI or CONUT, however, the malnutrition levels were less than 30%. Patients with malnutrition as assessed by the PG-SGA, NUTRISCORE, or NRI had lower intakes of energy and protein compared to normal patients. When NRI, PNI, or CONUT were used to identify malnutrition, lower levels of albumin, hemoglobin, total lymphocyte count, total cholesterol, and longer postoperative hospital stays were observed among patients with malnutrition compared to those without malnutrition. We found relatively high agreement between PG-SGA and NUTRISCORE; sensitivity was 90.86% and AUC was 0.78. When we compared NRI and PNI, sensitivity was 99.64% and AUC was 0.97. AUC ranged from 0.50 to 0.67 for comparisons between CONUT and each of the other nutritional screening tools. Conclusions: Our study suggests that PG-SGA and NRI have a relatively high agreement with the NUTRISCORE and PNI, respectively. Further cohort studies are needed to examine whether the nutritional status assessed by PG-SGA, NUTRISCORE, NRI, PNI, and CONUT predicts the gastric cancer prognosis.

Objective : The period of mechanical ventilator (MV)-dependent respiratory failure after cervical spinal cord injury (CSCI) varies from patient to patient. This study aimed to identify predictors of MV at hospital discharge (MVDC) due to prolonged respiratory failure among patients with MV after CSCI. Methods : Two hundred forty-three patients with CSCI were admitted to our institution between May 2006 and April 2018. Their medical records and radiographic data were retrospectively reviewed. Level and completeness of injury were defined according to the American Spinal Injury Association (ASIA) standards. Respiratory failure was defined as the requirement for definitive airway and assistance of MV. We also evaluated magnetic resonance imaging characteristics of the cervical spine. These characteristics included : maximum canal compromise (MCC); intramedullary hematoma or cord transection; and integrity of the disco-ligamentous complex for assessment of the Subaxial Cervical Spine Injury Classification (SLIC) scoring. The inclusion criteria were patients with CSCI who underwent decompression surgery within 48 hours after trauma with respiratory failure during hospital stay. Patients with Glasgow coma scale 12 or lower, major fatal trauma of vital organs, or stroke caused by vertebral artery injury were excluded from the study. Results : Out of 243 patients with CSCI, 30 required MV during their hospital stay, and 27 met the inclusion criteria. Among them, 48.1% (13/27) of patients had MVDC with greater than 30 days MV or death caused by aspiration pneumonia. In total, 51.9% (14/27) of patients could be weaned from MV during 30 days or less of hospital stay (MV days : MVDC 38.23±20.79 vs. MV weaning, 13.57±8.40; p<0.001). Vital signs at hospital arrival, smoking, the American Society of Anesthesiologists classification, Associated injury with Injury Severity Score, SLIC score, and length of cord edema did not differ between the MVDC and MV weaning groups. The ASIA impairment scale, level of injury within C3 to C6, and MCC significantly affected MVDC. The MCC significantly correlated with MVDC, and the optimal cutoff value was 51.40%, with 76.9% sensitivity and 78.6% specificity. In multivariate logistic regression analysis, MCC >51.4% was a significant risk factor for MVDC (odds ratio, 7.574; p=0.039). Conclusion : As a method of predicting which patients would be able to undergo weaning from MV early, the MCC is a valid factor. If the MCC exceeds 51.4%, prognosis of respiratory function becomes poor and the probability of MVDC is increased.

Methods: A total of 952 gastric cancer patients who underwent gastrectomy and chemotherapy from January 2009 to December 2012 were included. The patients were categorized into malnutrition and normal status according to five nutritional screening tools one month after surgery. The Spearman partial correlation, Cohen's Kappa coefficient, the area under the curve (AUC), sensitivity, and specificity of each two screening tools were calculated. Results: Malnutrition was observed in 86.24% of patients based on the PG-SGA and 85.82% based on the NUTRISCORE. When NRI or CONUT were applied, the proportions of malnutrition were < 30%. Patients with malnutrition had lower intakes of energy and protein than normal patients when assessed using the PG-SGA, NUTRISCORE, or NRI. Lower levels of albumin, hemoglobin, total lymphocyte count, and total cholesterol and longer postoperative hospital stays were observed among patients with malnutrition compared to normal patients when NRI, PNI, or CONUT were applied. Relatively high agreement for NUTRISCORE relative to PG-SGA was found; the sensitivity was 90.86%, and the AUC was 0.78. When NRI, PNI, and CONUT were compared, the sensitivities were 23.72% for PNI relative to NRI, 44.53% for CONUT relative to NRI, and 90.91% for CONUT relative to PNI. The AUCs were 0.95 for NRI relative to PNI and 0.91 for CONUT relative to PNI. Conclusions: NUTRISCORE had a high sensitivity compared to PG-SGA, and CONUT had a high sensitivity compared to PNI. NRI had a high specificity compared to PNI. This relatively high sensitivity and specificity resulted in 77.00% agreement between PNI and CONUT and 77.94% agreement between NRI and PNI. Further cohort studies will be needed to determine if the nutritional status assessed by PG-SGA, NUTRISCORE, NRI, PNI, and CONUT predicts the gastric cancer prognosis.

Background: Visceral pleural invasion (VPI) is a poor prognostic factor that contributes to the upstaging of early lung cancers. However, the preoperative assessment of VPI presents challenges. This study was conducted to examine intraoperative pleural carcinoembryonic antigen (pCEA) level and maximum standardized uptake value (SUVmax) as predictive markers of VPI in patients with clinical T1N0M0 lung adenocarcinoma. Methods: A retrospective review was conducted of the medical records of 613 patients who underwent intraoperative pCEA sampling and lung resection for non-small cell lung cancer. Of these, 390 individuals with clinical stage I adenocarcinoma and tumors ≤30 mm were included. Based on computed tomography findings, these patients were divided into pleural contact (n=186) and non-pleural contact (n=204) groups. A receiver operating characteristic (ROC) curve was constructed to analyze the association between pCEA and SUVmax in relation to VPI. Additionally, logistic regression analysis was performed to evaluate risk factors for VPI in each group. Results: ROC curve analysis revealed that pCEA level greater than 2.565 ng/mL (area under the curve [AUC]=0.751) and SUVmax above 4.25 (AUC=0.801) were highly predictive of VPI in patients exhibiting pleural contact. Based on multivariable analysis, pCEA (odds ratio [OR], 3.00; 95% confidence interval [CI], 1.14-7.87; p=0.026) and SUVmax (OR, 5.25; 95% CI, 1.90-14.50; p=0.001) were significant risk factors for VPI in the pleural contact group. Conclusion: In patients with clinical stage I lung adenocarcinoma exhibiting pleural contact, pCEA and SUVmax are potential predictive indicators of VPI. These markers may be helpful in planning for lung cancer surgery.
