PURPOSE: The medial meniscus is injured much more than the lateral meniscus. Because the medial meniscus is much larger in diameter, is thinner in its periphery and narrower in body than the lateral meniscus, and does not attach to either cruciate ligament. We evaluated correlations with sites of tear and history of trauma. METHODS AND MATERIALS: We reviewed retrospectively in 43 patients with meniscal tears on MRI(51 cases) and correlated them with history of trauma. RESULTS: The most common site of injury was the posterior horn of the medial meniscus(32/51), but high incidence of lateral meniscal tear compared with previous reports was seen. In the cases which had history of trauma, the posterior horn of medial meniscus was most commonly injured(26/34) and 5 meniscal tears were combined with meniscal tear in the other site. The tear in the anterior horn of the medial meniscus was seen only in a patient which had history of trauma and combined with meniscal tear in the other site. But in the meniscal tears without definite history of trauma, the incidence of meniscal tear was different from the meniscal tear with history of trauma. The incidence of lateral meniscal tear(11/17) was highter than medial meniscal tear and the posterior horn of lateral meniscus was commonly injured. CONCLUSION: We concluded that the medial meniscus was commonly injured, especially posterior horn, but in the cases which had no definite history of trauma, the lateral meniscus was commonly ipjured. An awareness of prevalent site of meniscal injuries may be helpful in the diagnostic interpretation of MR imaging of knee.

Thyroid cancer is the fourth most common malignant tumor in Korean women. It has been acknowledged for a long time that differentiated thyroid cancers have two basic ways of dissemination, lymphtic and hematogenous. Though lymphatic spread to regional lymph nodes is the typical presentation of papillary thyroid cancer of young patients, pulmonary metastasis are not uncommon in this age group. And it is interesting that almost all the patient with metastases to lung showed metastases to the regional neck lymph node. Abnormal chest X-ray of the patient of pulmonary metastasis shows only nonspecific diffuse micronodular pattern which is not easy to be differentiated. And here we report a case of pulmonary metastasis of thyroid papillary carcinoma which was mistaken for pulmonary miliary tuberculosis. It is suggested that more intensive consideration will be necessary for the diagnosis of pulmonary miliaria of children who shows neck mass.

PURPOSE: When using the emergency room of a tertiary hospital, both patients and their relatives or friends sometimes experience dissatisfaction and complain. Patient satisfaction deserves attention not only because it is an intrinsically worthy goal but also because it is a potentially significant mediator for promoting health and well-being. This study aims to identify patient's official complaints and to improve the quality of care in the Emergency Department (ED). METHODS: We investigated retrospectively 144 official complaints of visitors in 4 tertiary university hospital emergency centers between January 1, 2001, and December 31, 2003. RESULTS: Among those 144 official complaints from the 4 hospital emergency centers were 116 appropriate complaints, as determined by the inclusion criteria, and 212 detailed descriptions of dissatisfaction. The seven major categories of dissatisfactions were analyzed: rudeness or lack of kindness, delayed waiting time, insufficient explanation of patient condition, distrust of treatment, absence of a specialist, poor emergency-department environment, and high treatment fee. CONCLUSIONS: Dissatisfaction related to the lack of kindness was the most common problem in all four university hospital emergency centers. The next most important problem was the delayed time or distrust of treatment. The concrete causes of the complaints varied with the hospital. To improve the quality of care for patients in the ED, the hospital staff should be more attentive and kind and should explain the patient's condition in more detail. Reducing the waiting time is also important.

PURPOSE: We evaluated the hemodynamic statuses of patients after partial closure of atrial septal defects with fenestration due to pulmonary hypertension. MATERIALS AND METHODS: Seventeen adult patients underwent partial atrial septal defect closure and follow-up cardiac catheterization. We analyzed hemodynamic data and clinical parameters before and after closure. RESULTS: The median age at closure was 29 years old. The baseline Qp/Qs was 1.9+/-0.6. The median interval from the operation to the cardiac catheterization was 27 months. The CT ratio decreased from 0.55+/-0.07 to 0.48+/-0.06 (p<0.05). The mean pulmonary arterial pressure decreased from 50.0+/-11.5 mm Hg to 32.5+/-14.4 mm Hg (p<0.05), and the pulmonary resistance index decreased from 9.2+/-3.6 Wood units*m2 to 6.3+/-3.8 Wood units*m2 (p<0.05). Eleven patients (64.7%) continued to exhibit high pulmonary resistance (over 3.0 Wood units*m2) after closure. These patients had significantly higher pulmonary resistance indices and mean pulmonary arterial pressures based on oxygen testing before the partial closures (p<0.05). However, no significant predictors of post-closure pulmonary hypertension were identified. CONCLUSION: Despite improvement in symptoms and hemodynamics after partial closure of an atrial septal defect, pulmonary hypertension should be monitored carefully.

BACKGROUND: The shortage of human hearts for allotransplantation makes xenotransplantation a possible option for controllable organ providers. To detect acute xenograft rejection, invasive biopsy seems inevitable; however, this occasionally results in poor incision wound healing or infection. To date, no method of noninvasive imaging for early detection of xenograft rejection has been established. We hypothesized that ultrasound speckle tracking would better detect xenograft failure than routine left ventricular ejection fractions (EF). METHODS: From August 2013 to July 2015, a total of six cardiac heterotopic xenotransplants (α 1, 3-galactosyltransferase gene-knockout porcine heart) into cynomolgus monkeys were monitored with echocardiography every 3 to 7 days. M-mode and two-dimensional (2D)-EF measurements and myocardial strain analyses were performed. Cardiac xenograft pathology was reviewed from the immediate postoperative biopsy, as well as the necropsy. RESULTS: Myocardial speckle tracking analysis was feasible in all six cases. The longest survival was 43 days. Only one pathology-proven immunologic rejection occurred. Cardiac xenograft failure appeared as two types: a dilated pattern with decreased EF or a myocardial-thickening pattern with preserved EF. Both antibody-mediated rejection (n=1) and sepsis-induced myocardial dysfunction (n=2) revealed decreased radial or circumferential strains, but normal-range EF. Xenograft functional decline was significant with respect to radial or circumferential strain (P=0.028), but not to conventional M-mode or 2D-EFs (P=0.600, P=0.340, respectively). CONCLUSIONS: Radial and circumferential strains were significantly decreased in both types of xenograft failure, regardless of EF. Further studies are warranted to correlate the strain analysis and immunopathological details.
