STUDY DESIGN: Observational. PURPOSE: To develop a simple and comprehensive grading system for cervical discs that precisely, consistently and meaningfully presents radiologic and morphologic data. OVERVIEW OF LITERATURE: The Thompson grading system is commonly used to classify the severity of degenerative lumbar discs on magnetic resonance imaging (MRI). Inherent differences in the morphological and physiological characteristics of cervical discs have hindered development of precise classification systems. Other grading systems have been developed for degenerating cervical discs, but their versatility and feasibility in the clinical setting is suboptimal. METHODS: MRIs of 46 human cervical discs were de-identified and displayed in PowerPoint format. Each slide depicted a single disc with a normal (grade 0) disc displayed in the top right corner for reference. The presentation was given to 25 physicians comprising attending spine surgeons, spine fellows, orthopaedic residents, and two attending musculoskeletal radiologists. The grading system included Grade 0 (normal height compared to C2-3, mid cleft still visible), grade 1 (dark disc, normal height), grade 2 (collapsed disc, few osteophytes), and grade 3 (collapsed disc, many osteophytes). The ease of use of the system was gauged in the participants and the interobserver reliability was calculated. RESULTS: The intraclass correlation coefficient for interobserver reliability was 0.87, and 0.94 for intraobserver reliability, indicating excellent reliability. Ninety-five percent and 85 percent of the clinicians judged the grading system to be clinically feasible and useful in daily practice, respectively. CONCLUSIONS: The grading system is easy to use, has excellent reliability, and can be used for precise and consistent clinician communication.

BACKGROUND: We aimed to compare the diagnostic accuracy of the Alere Triage Cardio3 Tropinin I (TnI) assay (Alere, Inc., USA) and the PathFast cTnI-II (Mitsubishi Chemical Medience Corporation, Japan) against the central laboratory assay Singulex Erenna TnI assay (Singulex, USA). METHODS: Using the Markers in the Diagnosis of Acute Coronary Syndromes (MIDAS) study population, we evaluated the ability of three different assays to identify patients with acute myocardial infarction (AMI). The MIDAS dataset, described elsewhere, is a prospective multicenter dataset of emergency department (ED) patients with suspected acute coronary syndrome (ACS) and a planned objective myocardial perfusion evaluation. Myocardial infarction (MI) was diagnosed by central adjudication. RESULTS: The C-statistic with 95% confidence intervals (CI) for diagnosing MI by using a common population (n=241) was 0.95 (0.91-0.99), 0.95 (0.91-0.99), and 0.93 (0.89-0.97) for the Triage, Singulex, and PathFast assays, respectively. Of samples with detectable troponin, the absolute values had high Pearson (R(P)) and Spearman (R(S)) correlations and were R(P)=0.94 and R(S)=0.94 for Triage vs Singulex, R(P)=0.93 and R(S)=0.85 for Triage vs PathFast, and R(P)=0.89 and R(S)=0.73 for PathFast vs Singulex. CONCLUSIONS: In a single comparative population of ED patients with suspected ACS, the Triage Cardio3 TnI, PathFast, and Singulex TnI assays provided similar diagnostic performance for MI.

OBJECTIVE: In this study we utilized the Surveillance, Epidemiology and End-Results (SEER) registry to identify risk factors for lymphatic spread and determine the incidence of pelvic and para-aortic lymph node metastases in patients with uterine papillary serous carcinoma (UPSC) and uterine clear cell carcinoma (UCCC) who underwent complete surgical staging and lymph node dissection. METHODS: Nine hundred seventy-two eligible patients diagnosed between 1998 to 2009 with International Federation of Gynecology and Obstetrics (FIGO) 1988 stage IA-IVA UPSC (n=685) or UCCC (n=287) were identified for analysis. Binomial logistic regression was used to determine risk factors for lymph node metastasis, with the incidence of pelvic and para-aortic lymph node metastases reported for each FIGO primary tumor stage. The Cox proportional hazards regression model was used to determine factors associated with overall survival. RESULTS: FIGO primary tumor stage was the only independent risk factor for lymph node metastasis (p<0.01). The incidence of pelvis-only and para-aortic lymph node involvement according to the FIGO primary tumor stage were as follows: IA (2.3%/3.8%), IB (7.5%/5.2%), IC (22.5%/16.9%), IIA (20.8%/13.2%), IIB (25.7%/14.9%), and III/IV (25.7%/24.3%). Prognostic factors for overall survival included lymph node involvement (hazard ratio [HR], 1.42; 95% confidence interval [CI], 1.09 to 1.85; p<0.01), patient age >60 years (HR, 1.70; 95% CI, 1.21 to 2.41; p<0.01), and advanced FIGO primary tumor stage (p<0.01). Tumor grade, histologic subtype, and patient race did not predict for either lymph node metastasis or overall survival. CONCLUSION: There is a high incidence of both pelvic and para-aortic lymph node metastases for FIGO stages IC and above uterine papillary serous and clear cell carcinomas, suggesting a potential role for lymph node-directed therapy for these patients.

PURPOSE: The aim of this study is to analyze the outcome of a variety of treatments, including local surgical treatments, diverting stoma, and combined medical therapy, for patients with a rectovaginal fistula complicating Crohn's disease. METHODS: Between 1994 and 2003, twenty-one patients with a rectovaginal fistula complicating Crohn's disease from a prospectively compiled 422-patient Crohn's disease database were reviewed. RESULTS: All three patients treated by seton and fibrin glue recurred despite having relatively long tracts. Of six patients with infliximab treatment combined with a seton procedure, five patients had an improvement of their symptoms, but were not cured. Of eight patients with a transanal or endovaginal advancement flap techniques, three had successful closure, three eventually required a proctectomy, and two had a recurrent fistula without symptoms. Four (2 without any local treatments, and 2 with seton placement) of 16 patients who had a diverting stoma during treatment had successful closure. All proctectomy patients (n=8) had rectal involvement of Crohn's disease. Two patients who underwent a proctectomy with a presumptive diagnosis of ulcerative colitis and indeterminate colitis turned out to have Crohn's disease. Overall, except for the proctectomy patients, seven patients (54%) had successful closure, but six (four without symptoms, and two with symptoms) following a wide spectrum of treatments had recurrence after a mean follow-up of 44 months. CONCLUSIONS: Combining different treatments for a rectovaginal fistula in Crohn's disease can be successful in a reasonable number of cases. The presence of uncontrolled perianal sepsis and/or complicated anorectal problems is likely to lead to a proctectomy.

INTRODUCTIONLong QT syndrome (LQTS), an inherited cardiac arrhythmia, is a disorder of ventricular repolarisation characterised by electrocardiographic abnormalities and the onset of torsades de pointes leading to syncope and sudden death. Genetic polymorphisms in 5 well-characterised cardiac ion channel genes have been identified to be responsible for the disorder. The aim of this study is to identify disease-causing mutations in these candidate genes in a LQTS family.
MATERIALS AND METHODSThe present study systematically screens the coding region of the LQTS-associated genes (KCNQ1, HERG, KCNE1, KCNE2 and SCN5A) for mutations using DNA sequencing analysis.
RESULTSThe mutational analysis revealed 7 synonymous and 2 non-synonymous polymorphisms in the 5 ion channel genes screened.
CONCLUSIONWe did not identify any clear identifiable genetic marker causative of LQTS, suggesting the existence of LQTS-associated genes awaiting discovery.

OBJECTIVE: The object of this study was to assess the accuracy of dipyridamole stress intravenous (IV) myocardial contrast echocardiography (MCE) using pulse inversion harmonic imaging and PESDA in the detection of perfusion defect in the patients with coronary artery disease in comparison with dipyridamole stress Tc-99m sestamibi SPECT. METHODS: Total 46 patients (29 males, mean age 64 years old) were consecutively enrolled. Patients with prior myocardial infarction were excluded. MCE and Tc-99m sestamibi SPECT were performed at the same day during rest and after 0.56 or 0.84mg/Kg dipyridamole infusion. Continuous IV infusion of PESDA (2-5 mL/min) was administered while obtaining triggered (1:1) end-systolic apical 2, 4 chamber and long axis views. Tc-99m sestamibi was injected 3 minutes after dipyridamole. Tc-99m sestamibi SPECT images were obtained one hour later. Coronary angiography was followed within two days in all patients. Tc-99m sestamibi SPECT images were matched to the sixteen segments of left ventricle according to American Society of Echocardiography for segmental comparison. Both images were analyzed visually. Results Using coronary angiography as the standard, MCE showed overall sensitivity of 70.7%, specificity of 95.8%, positive predictive value (PPV) of 87.8% and negative predictive value (NPV) of 88.5% in the detection of coronary atherosclerosis (70% stenosis). Tc-99m sestamibi SPECT showed sensitivity of 75.6%, specificity of 98.9%, PPV of 96.8% and NPV of 90.6%. The overall concordance rate between MCE and Tc-99m sestamibi SPECT for the detection of perfusion defects was 86.9% (Cohen's kappa value 0.63) according to the coronary territory and 86.8% (Cohen's kappa value 0.55) according to segmental analysis. CONCLUSION: Dipyridamole stress IV MCE using pulse inversion harmonic imaging and PESDA is feasible and comparable to Tc-99m sestamibi SPECT in identifying significant coronary stenosis and inducible myocardial perfusion defects in the patients with coronary artery disease. MCE using pulse inversion harmonic imaging seems to be a promising modality for assessing myocardial perfusion in the patients with suspected coronary artery disease.

Cesarean hysterectomy is associated with high risks of severe blood loss, postoperative complication, and maternal morbidity. This study was undertaken to identify the risk factors of cesarean hysterectomy and to reduce the postoperative complications and maternal morbidity. There were 6,362 deliveries between January 1992 and December 1996 at department of obstetrics and gynecology, Inchon Christian Hospital. 1'he results of this study were as follows, 15 cases of cesarean hysterectomy were performed during this period. Cesarean hysterectomy was performed in 10 cases (0.32 %) among 3178 cesarean deliveries and in 5 cases (0.16 %) among 3184 vaginal deliveries. The incidence of cesarean hysterectomy was 0.24 % (15/6,362). The age of patients ranged from 24 to 38 years old. The maternal mortality and morbidity were 0 % (0/15) and 86.7% (13/15), respectively. Indications for cesarean hysterectomy were uterine atony (53.3 %), uterine myoma with pregnancy (20.0 %), placenta accreta and/or increta(20.0 %), and placenta previa (6.7 %) in orders. The associated risk factors of cesarean hysterectomy were prior cesarean delivery (46.7 %) and placenta previa (6.7 %). The postoperative complications were anemia (60.0%), febrile morbidity (13.3 %), paralytic ileus (6.7 %), and wound disruption (6.7 %). We concluded that risk factors of cesarean hysterectomy were cesarean delivery, prior cesarean delivery, uterine myoma with pregnancy, placenta accreta and/or increta, and placenta previa and that sufficient fresh blood and careful prenatal care were needed in risk group of postpartum bleeding.

Growth Patterns of cranium measured directly as head circumference have been well documented. With the recent progress in CT, it is easy to measure the size and cross sectional area of the structure. The author chose themidvnetricular level of brain CT scan and measured the product of maximum anteroposterior and lateral dimension and cross sectional area. The age of infants ans children was 0 to 2 years old. The author obtained the following results through statistical analysis; 1. The maximum anteroposterior dimension and the cross sectional area were obtained through the computerized program of CT scanner. Using these measurements, monthly growth curve was obtained and which shows accelarated growth in the initial 12 months especially during the first four months, and followd by reduced rate of growth in the next 12 months. 2. Comparing the size of the calvarium between sexed,females' were somewhat larger than males', but there was no statistical significance. 3. Comparing the crosssectional area with the head circumference, high correlation was seen(correlation coefficient=0.96). Similarelationship was also seen between the product of cranial linear dimensions and the head circumference(correlationcoefficient=0.93). Also statistically significant relationship was noted between the cross sectional area and theproduct of the cranial linear dimensions(correlation coefficient=0.97). 4. Using the cross sectional area and theproduct of cranial linear dimenstions, monthly average value and the 95% significant range were obtained which canbe used as indices for the growth and development of cranium. Of these, the product of cranial linear dimensionscan eadily be measured by brain CT images, which may be useful on practical basis.

Etretinate(Ro 10-9359), an aromatic analogue of vitamin A acid, has been known to be effective in the treatment of psoriasis, Darier's disease, pityriasis rubra pilaris, ichthyosis, and palmoplantar keratoderma when administered orally. In this experiment, we compared the therapeutic and side effects between a group with high dose therapy(initially 75mg of etretinate a day) and an another group with low dose therapy(initially 40mg of etretinate a day). We also observed whether the pretreatment followed by combined treatment with vitamin E could potentiate the therapeutic effect as well as reduce the side effects of oral etretinate. This experiment comprised 102 moderate to severe psoriatic patients. The following results were obtained from this experiment. 1. Fifty-six among 92 patients(61%) who were treated with etretinate for more than 4 weeks showed good to excellent therapeutic effect. 2 The high dose therapy was more effective, but showed more side effects than low dose therapy. 3 Vitamin E did not potentiate the effect of etretinate. In low dose therapy, the pretreatment followed by combined treatment with vitamin E showed a tendency to reduce the side effects of etretinate.

Since the early discovery of H-reflex by Hoffmann in 1918 there have been a great number of articles in the literature suggesting its clinical used by Magladery in the early 1950. Our experiments about measurement of latent time in H-reflex were performed on 40 normal male adult(composed of medicos and medical officers) and 82 patients(lumbago 40, lumbar disc 42) admitted at CAFGH from January '79. to August '79. The result about normal adult are as follows: 1) The mean value and the standard deviation of the latent time in normal adult(height 171+/-5.14 cm) is 27.74+/-1.86 msec at right leg, 27.77+/-1.64 msec at left one respectively. 2) There may be a linear relationship between latency and the height of normal adult and the difference between right and left is revealed 0.15+/-0.19 msec. We compare the measurementon the 82 patients group with the normal adult experimental groups in addition literatures review.
