Increased carotid intima-media thickness is associated with higher SYNTAX score

The main purpose of this study was to investigate the relation between carotid intima-media thickness (CIMT) and coronary artery disease (CAD) complexity. Consecutive patients (n = 360) with CAD confirmed by coronary angiography were enrolled. Mean CIMT and the overall SYNTAX score (SXscore) were 0.87 ± 0.12 mm and 15 ± 9, respectively. In univariate analysis, there was a significant correlation between the overall SXscore and CIMT (r = .42, P < .001), age (r = .23, P < .001), hypertension (r = .27, P = 0.001), diabetes (r = 0.11, P = 0.02), smoking (r = .24, P = .01), dyslipidemia (r = .2, P = 0.03), and β-blocker use (r = .19, P < .001). In multivariate analysis, CIMT (β = .34, P < .001) and age (β = .11, P < .019) were independently associated with SXscore. We have demonstrated a significant relation between CIMT and SXscore. Although this study is correlative and no causative conclusions can be drawn, our findings suggest that increased CIMT could reflect complex coronary artery lesions.     

Chylomediastinum Following Tracheal Surgery

Fever of unknown origin (FUO) is a diagnostic challenge for the practising physician. Detailed medical history, physical examination, non-invasive laboratory tests, and radiologic examinations compose the first level in the diagnostic approach to the FUO. When a diagnosis cannot be established with these procedures, some invasive diagnostic techniques and finally exploratory laparotomy are performed. Although advanced diagnostic measures and imag-ing-guided less invasive procedures have decreased the need, laparotomy remains as a final diagnostic method for FUO cases. In this study we evaluate the role and importance of laparotomy in the diagnosis of our FUO cases. In 17 out of 126 patients (8 male, 9 female, the median age 35.8 years) hospitalized in our clinic between 1982 and 2002 with the diagnosis of FUO, the diagnosis was established by laparotomy. The diagnosis was made directly in 13 patients, and indirectly (by excluding other diseases) in 2 patients. In several FUO series, the contribution of laparotomy to the diagnosis of FUO was reported as 27-100%. This rate was found to be 88% in the present study. During laparotomy on 17 cases, tissue samples were taken from spleen, liver, intra-abdominal and mesenteric lymph nodes. Pathologic examination of these tissue samples revealed miliary tuberculosis in 4; non-Hodgkin’s lymphoma in 3; Hodgkin’s lymphoma in 3; liver tumour in 1; hairy cell leukemia in 1; peritonitis carcinomatosis in 1. In the patients with miliary tuberculosis, the liver (3) and/or spleen (2), and/or lymph node (3) revealed caseating granulomas. Laparotomy diagnosed 3 of 5 cases whose abdominal ultrasonography and computerized tomography were normal. In conclusion, although advanced diagnostic methods decreased the need for laparotomy in FUO, if non-invasive and invasive diagnostic measures fail, laparotomy may contribute to the diagnosis. The selection of the patient and the timing are important for laparotomy.     

Patients with Tombstoning Pattern on the Admission Electrocardiography Who Have Undergone Primary Percutaneous Coronary Intervention for Anterior Wall ST‐Elevation Myocardial Infarction: In‐Hospital and Midterm Clinical Outcomes

Background: A tombstoning pattern (T‐pattern) is associated with in‐hospital poor outcomes patients with ST‐segment elevation myocardial infarction (STEMI), but no data are available for midterm follow‐up. We sought to determine the prognostic value of a T‐pattern on admission electrocardiography (ECG) for in‐hospital and midterm mortality in patients with anterior wall STEMI treated with primary percutaneous coronary intervention (PCI). Methods: After exclusion, 169 consecutive patients with anterior wall STEMI (mean age: 55 ± 12.9 years; 145 men) undergoing primary PCI were prospectively enrolled in this study. Patients were classified as a T‐pattern (n = 32) or non–T‐pattern (n = 137) based upon the admission ECG. Follow‐up to 6 months was performed. Results: In‐hospital mortality tended to be higher in the T‐pattern group compared with non–T‐pattern group (9.3% vs 2.1% respectively, P = 0.05). All‐cause mortality was higher in the T‐pattern group than non–T‐pattern group for 6 month (P = 0.004). After adjusting the baseline characteristics, the T‐pattern remained an independent predictor of 6‐month all‐cause mortality (odds ratio: 5.18; 95% confidence interval: 1.25–21.47, P = 0.02). Conclusion: A T‐pattern is a strong independent predictor of 6‐month all‐cause mortality in anterior STEMI treated with primary PCI. Therefore, it may be an indicator of high risk among patients with anterior wall STEMI.     

Reliability of four different computerized cephalometric analysis programs

The aim of this investigation was to compare the traditional method of manual cephalometric tracing with four different computerized tracing programs, where the lateral cephalograms were scanned at 300 dpi and digitized onscreen. Thirty randomly selected cephalometric radiographs were used in this study. Four programs Dolphin Imaging, Vistadent, Nemoceph, and Quick Ceph were evaluated. Three dental, 11 skeletal, and 1 soft tissue parameters were measured that consisted of 5 linear and 10 angular measurements. Statistical analysis was carried out using multivariate analysis of variance and Box's and Levene's tests. No statistically significant difference was found between manual tracing and the computerized tracing programs. The measurements obtained with the cephalometric analysis programs used in the study were reliable.
