OBJECTIVE: Although cor pulmonale due to chronic lung disease was not uncommon, there was uncertainty in its diagnosis due to the difficulty in measuring functional and anatomical changes of right heart and pulmonary vascular system. Among various non-invasive diagnostic methods presented so far, no ideal standard diagnostic criterion has been established. The authors attempted to know positive diagnostic ratio of cor pulmonale and to study the presence of the relationship between these diagnostic criteria when electrocardiographic and echocardiographic diagnostic criteria for cor pulmonale were applied to the patients with chronic lung disease. And we investigated the usefulness of echocardiogaphic diagnostic criteria for the diagnosis. METHODS: One electrocardiographic and two echocardiographic diagnostic criteria were applied to 38 patients with chronic lung disease(21 pulmonary emphysema and 17 chronic advanced pulmonary tuberculosis) for the diagnosis of cor pulmonale. Comparison was also made in their relationship. Then pulmonary artery diameter, measurement of pulmonary function test and echocardiographic examination and radio-nuclear right ventricular ejection faction were compared between the groups to ensure each criterion was satisfied. RESULTS: 1) When the three diagnostic criteria for confirming the cor pulmonale, electrocardiographic rriterion(right ventricular hypertrophy), right ventricular dimension criterion(right ventricular end-diastolic dimension>25mm, RVDd>25mm), and right ventricular wall thickness criterion (right ventricular wall thickness>6mm, RVWT>6mm) were applied to the patients, the positive rate were 32%(12/37), 30%(10/33) and 17%(6/36) respectively. A statistically significant correlation between electrocardiographic criterion and right ventricular wall thickness criterion was found to exist. 2) Various parameters of pulmonary function test and echocardiographic examination were compared in the patient groups with and without cor pulmonale when each non-invasive diagnostic criterion was applied to all patients. Followings are the results. (1) In the positive group on electrocardiographic criteria, vital capacity, forced vital capacity, and arterial oxygen tension were significantly smaller than in the negative group on electrocardiographic criterion(p<0.05), and the echocardiographic parameters of right ventricle, ie. end-diastolic area, end-systolic area, end-diastolic dimension, end-systolic dimension, mid-ventricular short axis and maximal short axis in positive group were significantly larger than in the negative group. (2) In the positive group on right ventricular diastolic dimension criterion(RVDd>25mm), percentage forced expiratory volume in 1 second and forced expiratory flow 25-75% were significantly smaller than in the negative group on right ventricular diastolic dimension criterion. (3) In the positive group on right ventricular wall thickness criterion(RVWT>6mm), vital capacity, forced vital capacity, forced expiratory volume in 1 second, forced expiratory flow 25-75% and arterial oxygen tension were significantly smaller than in the negative group on right ventricular wall thickness criterion. CONCLUSION: When several non-invasive diagnostic criteria for cor pulmonale were applied to the patients with chronic lung disease, there were some differences in its positive diagnostic ratio depending on the applied diagnostic criteria. There was also a statistically significant correlation between electrocardiographic criterion and right ventricular wall thickness criterion. When each diagnostic criterion was applied to the patients, significant differences were found in several parameters resulted from pulmonary function test and echocardiographic examination based on presence or nonpresence of cor pulmonale. But no difference in the ejection fraction measured by radio-nuclear method was shown between cor pulmonale group and non cor pulmonale group. Consequently it was suggested that applying echocardiographic criteria in addition to electrocardiographic criterion for the diagnosis of cor pulmonale in the patients with chronic lung disease is clinically useful.

We treated 27 cases of the complete dislocation of the acromioclavicular joint with the modified Weaver and Dunn procedure described by Shoji et al, which is resection of the lateral end of the clavicle and bone block transfer of the coracoacromial ligament, from July 1987 to December 1989. Twenty-one patients were followed for an average of fourteen months and the brief summary of the observations are as follows: 1. The peak incidence was in 3rd and 4th decades and much more prevalent in male (76%). 2. The most common cause of the injury was traffic accident and followed by fall down. 3. In functional evaluation by the Weitzmann criteria, an excellent result was seen in fourteen cases; a good result, in five; a fair result, in two. 4. The comparision of the coracoclavicular interval ratio before surgery with that after surgery facilitated the evaluation of the effectiveness of the coracoclavicular ligament reconstruction. 5. There were no major complications that could affect to end result.

Tattoos, which people choose to have performed for various reasons, can have multiple colors, ranging from conventional black to red, yellow, blue, and others. As tattoos have become increasingly popular, the need for tattoo removal has also grown, and the most commonly used method for removal is a laser. However, the extent to which various types of lasers remove different tattoo pigments is clearly important. Although extensive research has been done on black tattoos, red tattoos have not been adequately studied, and there are few case reports on red tattoos. We present a case of effective removal of a red tattoo from the lips using a picosecond laser.

We report on a 28 years old female with recurred cardiac myxomas who presented with dizziness, headache, and blurred vision. She had an excision of biatrial atrial myxomas 10 years age. Varying sized multiple cerebral aneuysms and myxomas in left atrium and left ventricle were found on a cerebral angiogram and echocardiogram, respectively. After wide excision including interatrial septum and part of left ventricular septum, her symptoms were much improved.

Background: Thrombocytopenia is a condition where platelet counts are below the normal range (< 150 ×103 /µL), resulting in a higher risk of bleeding and affecting the results of hip arthroplasty. We assessed the impact of preoperative platelet counts on the clinical results of patients who underwent hip arthroplasty. Methods: Between April 2003 and March 2023, 437 patients (451 hips), who had preoperative thrombocytopenia of less than 150 ×103 /µL platelets, underwent hip arthroplasty. Preoperative platelet levels were categorized into severe thrombocytopenia (< 50 ×103 /µL) and non-severe thrombocytopenia (50–149 ×103 /µL). Total blood loss, operation time, requirement of transfusion, amount of transfusion, duration of surgical wound oozing, length of hospital stay, mortality rate at 1 year after surgery, and any complication were compared between the 2 groups. Results: No notable differences were observed in the surgery time or the total amount of blood loss between the groups. The requirement of transfusion and the amount of transfused blood were higher in the severe thrombocytopenia group. Prolonged oozing was found in around 18% in both groups, while periprosthetic joint infections occurred in 3 of the non-severe thrombocytopenia group. No significant difference was noted in the duration of hospital stay (25.6 ± 18.3 days vs. 19.4 ± 16.6 days, p = 0.067) and 1-year mortality (22.2% vs. 11.8%, p = 0.110). Conclusions Hip arthroplasties are safe for patients with low platelet counts and do not lead to prolonged hospital stays. On the other hand, patients with severe thrombocytopenia tend to need blood transfusions more frequently than those with less severe thrombocytopenia.
