PURPOSE: The purpose of this study is to assess the sonographic findings of Osgood-Schlatter disease with correlation to radiographic findings and to determine value of sonography in the diagnosis of Osgood-Schlatter disease. MATERIALS AND METHODS: The population consist of 22 cases of Osgood-Schlatter disease and 15 healthy subjects of the same age range for comparison. The sonographic study was carried out with real time units equipped with linear probe of 7 MHz frequency. Radiography and sonography were done in all cases and follow-up sonography was performed in 10 cases. RESULTS: The sonographic features of the Osgood-Schlatter disease were swelling of cartilage over the anterior tibial tuberosity ossification center in 16 cases, fragmentation and/or irregularities of the ossification center of the anterior tibial tuberosity in 14 cases, localized thickening of the pateliar tendon in 14 cases, ossicles in the thickened pateliar tendon in 3 cases, and distension of the infrapatellar bursa in 2 cases. Fifteen of 22 cases of Osgood-Schlatter disease had abnormal findings on radiographs and sonograms. Out of 7 cases which had normal radiograph and abnormal findings on sonogram, 6 cases showed pateliar tendon thickening, cartilage swelling, and/or distended infrapatellar bursa and one case showed fragmentation of anterior tibial tuberosity on sonogram. CONCLUSION: Sonographic evaluation of Osgood-Schlatter disease provided a clear picture about pathologic changes in the superficial soft tissues and in the cartilage and also yielded the same diagnostic information on bony change as radiography Sonography is a reliable and useful method for the evaluation of young patients with clinically suspected Osgood-Schlatter disease.

BACKGROUND: The execution of fibular allograft augmentation in unstable proximal humerus fractures (PHFs) was technically demanding. In this study, the authors evaluated the clinical and radiographic outcomes after tricortical iliac allograft (TIA) augmentation in PHFs. METHODS: We retrospectively assessed 38 PHF patients treated with locking-plate fixation and TIA augmentation. Insertion of a TIA was indicated when an unstable PHF showed a large cavitary defect and poor medial column support after open reduction, regardless of the presence of medial cortical comminution in preoperative images. Radiographic imaging parameters (humeral head height, HHH; humeral neck-shaft angle, HNSA; head mediolateral offset, HMLO; and status of the union), Constant score, and range of motion were evaluated. Patients were grouped according to whether the medial column support after open reduction was poor or not (groups A and B, respectively); clinical outcomes were compared for all parameters. RESULTS: All fractures healed radiologically (average duration to complete union, 5.8 months). At final evaluation, the average Constant score was 73 points and the mean active forward flexion was 148°. Based on the Paavolainen assessment method, 33 patients had good results and 5 patients showed fair results. The mean loss of reduction was 1.32 mm in HHH and 5.02% in HMLO. None of the parameters evaluated showed a statistically significant difference between the two groups (poor and not poor medial column support). CONCLUSIONS: In unstable PHFs, TIA augmentation can provide good clinical and radiological results when there are poor medial column support and a large cavitary defect after open reduction.

Two cases of abnormalities of the left ventricular wall(left ventricular aneurysm or diverticulum) are presented. A saccular deformity of the left ventricle may be and aneurysm or a diverticulum. In one case, the defect seems to be subcalvular aneurysm(or fibrous diverticulum) or aneurysm of the membranous ventricular septum; this lesion seems to be a natural consequence of spontaneous closure of a defect of the membranous septum. The other case, it seems that the defect is ventricular aneurysm with syndrome of myocardial infarction and normal coronary arteries, or double or accessory chambered left ventricle. The thromboembolic phenomenon was noted on a left frontoparietal lobe of brain. Both cases have the diagnosis supported by cardiac catheterization and angiography. The clinical, angiographic and pathologic characteristic of diverticulum and aneurysm of the heart are reviewed, and an attempt is made to clarify the concept of aneurysm and diverticulum of the heart.

The goals of this study were 1) to present pre-surgical naso-alveolar molding(PNAM) appliance for bilateral cleft lip and palate treatment and 2) To evaluate the effects of the PNAM appliance on the alveolar molding of the premaxilla and the lateral segments. Subjects consisted of 8 bilateral cleft lip and palate infants (7 males and 1 female, mean age at first visit = 61.6 days after birth) who were treated with PNAM appliances in Department of Orthodontics, Seoul National University Dental Hospital. Average alveolar cleft gap between the premaxilla and lateral segment was 8.09+/- 5.03mm and average duration of alveolar molding treatment was 8.8+/-3.1weeks. These patients' models were obtained at initial visit (T0) and after alveolar molding (T1). 20 linear and 14 angular variables were measured by using photometry and digital caliper. All statistical analyses were performed by Microsoft Excel 97 program. Paired t-test was used to discriminate the effect of alveolar molding by PNAM appliance. 1. Closure of the alveolar cleft gap in bilateral cleft cases by molding therapy was completed successfully. 2. Alveolar molding inhibited outward growth of lateral segments and produced inward bending of lateral segments. 3. By bending the anterior part of the vomer, the premaxilla could be rotated and moved posteriorly via alveolar molding. Conclusion : This appliance can be applied to bilateral cleft lip and palate infants with satisfactory result before cheiloplasty.

PURPOSE: To clarify the relationship between various factors (sociodemographic factors, health behavioral risk factors and health status, and diabetic factors) related to diabetic retinopathy and to suggest improvements regarding the associated medical examination. METHODS: The subjects were 1,444 diabetic patients diagnosed in the 5th Korean National Health and Nutrition Examination Survey (KNHANES), aged 19 years or older, who underwent non-mydriatic fundus photography. The criteria for diagnosing diabetes were a fasting glucose level ≥ 126 mg/dL and a previous diagnosis of diabetes or currently undergoing treatment. The diagnosis of diabetic retinopathy followed the modified Airlie House classification. Univariate and multivariate analyses of diabetic retinopathy were performed. RESULTS: Among the 1,444 patients who were diagnosed with diabetes, 277 had diabetic retinopathy; the prevalence rate was 19.18%. The higher the body mass index, the lower the risk of diabetic retinopathy by 0.924 times (p = 0.001; 95% confidence interval [CI], 0.883–0.966). The longer the duration of diabetes, the greater the risk of diabetic retinopathy; the prevalence period group of more than 11 years had a 26.025-fold higher risk than the newly diagnosed group (p < 0.001; 95% CI, 10.840–62.482). The risk of diabetic retinopathy increased with the hemoglobin A1c (HbA1c) level; the risk was 5.973-fold higher in the group with HbA1c above 11.0% (p < 0.001; 95% CI, 2.984–11.956) compared with the group with HbA1c < 6.0%. The risk of diabetic retinopathy was 2.050-fold greater with insulin injections (p = 0.003; 95% CI, 1.284–3.275). CONCLUSIONS: The risk of diabetic retinopathy was higher in patients with a longer duration of diabetes, a high HbA1c level, and in those using insulin. These findings highlight the need for early education and ophthalmologic examinations for at-risk patients.

PURPOSE: The purpose of this study is to develop three-dimensional computerized anthropometry(3DCA) and to compare its reliability and accuracy 3DCA with manual anthropometry(MA) for measurement of lips and nasal deformities in unilateral cleft lips and palate(UCLP) patients. METHODS: Samples were consisted of six UCLP patients whose facial plaster models were available immediately before and 3 months after the cleft lip surgery. MA of the facial plaster models was carried out using an electronic caliper. In 3DCA, three-dimensional auto- measuring program was used to digitize landmarks and to measure three-dimensional virtual facial models (3DVFM), which was generated with a laser scanner and 3D virtual modeling program. Intraclass correlation coefficients(ICC) were calculated to evaluate reliability and reproducibility of the variables in both methods, and Wilcoxon's signed rank test was done to investigate the difference in values of the same variables of facial models of each patient between two methods. RESULTS: All ICC values were higher than 0.8, so both methods could be considered reliable. Although most variables showed statistical differences between two methods(p<0.05), differences between mean values were very small and could be considered not significant in clinical situation. CONCLUSION: In clinical situation, 3DCA can be an objective, reliable and accurate tool for evaluation of lips and nasal deformities in the cleft patients.

Atrial Septal Defect(ASD) is usually suspected clinically but requires a confirmative diagnostic procedure before surgical repair. Conventional transthoracic echocardiography has relatively high sensitivity and specificity for ASD, but difficulty in visualizing the ASD occasionally. Transesophageal echocardiography has special advantages for investigating the posteriorly located cardiac structures, including the atrial septum, which is imaged perpendicularly at a relatively short distance. We describe a case in which ostium secundum ASD was not visualized by conventional transthoracic echocardiography, but was diagnosed confidently by transesophageal echocardiography. It is concluded that transesophageal echocardiography appears to be a promising diagnostic tools for the evaluation of ASD on the basis of its ability to provide excellent imaging of the entire atrial septum and related posterior cardiac structures.

Actinomycosis is an oppoturnistic infection of actinomyces, which are relatively avirulent endogenous oral commensals. After trauma or infection, they breach the normally protective mucosal barriers to invade adjacent soft tissue structures. Lesions routinely contain other bacteria, the normal resident flora at the site of primary infection, which act synergistically with actinomyces species to provoke this unique infection, which range from an acute suppurative process to a chronic fibrotic process. According to epidemic studies about pelvic actinomycosis, it should be significantly related to IUD(intrauterine device). It is accounted that IUD cause chronic intrauterine infection, tissue injury and act as nucleus for parasitic infestation. Here we present a case of pelvic actinomycosis related to IUD with brief review of the concerned literature.
