An analysis of echocardiograms was made in 50 patients with pericardial effusion of various origins, diagnosed by clinical and M-mode echocardiographic examinations. In these cases the estimated volume of pericardial effusion ranged between 40 ml and 999 ml. The width of echo-free space behind the left ventricular wall which reflect the amount of effusion showed a significant positive correlation with the systolic excursion and the diastolic mean velocity of both right and left ventricular epicardial surfaces. The echocardiographic patterns of so-called pseudo-mitral valve prolapse and a notch on the right ventricular epicardial surface during systole were found more frequently in patients with large pericardial effusion. Thus, in pericardial effusion, and echocardiographic examination is useful for the visualization of the abnormal motions of cardiac structures as well as for its diagnosis.

One case of Behcet's disease with multiple aneurysms in both common carotid arteries and abdominal aorta is presented with brief review of the literatures. A 26-year-old woman had slowly enlarging pulsatile masses in both sides of neck and recurrent ulcerations in oral cavity and genitalia. One day prior to admission, aphasia, right facial nerve palsy and right hemiplegia suddently developed. Brain CT showed acute infarction in left basal ganglia. Both Carotid Angiography and abdominal Aortography demonstrated mulitple aneurysms in both common carotid arteries and abdominal aorta with organizion thrombi and thromboembolism of internal carotid artery.

Soft Contact Lenses(SCL) are used widely instead of glasses among young female, especially university students, for cosmetic purpose. Usually Shirmer test has been used to evaluate the tear production state however more objective method is the tear film break up time. Authors evaluated the effect of soft contact lenses on BUT. We selected 40 femalse wearing on Hyper-Thin soft contact lenses, and One Soflens(Baush and Lomb) as soft contact lens wearing group and 30 females without no evidence of systemic disease or ocular disease affecting on tear production as normal control group. And authors studied mean value of BUT at each group, difference of BUT between 2 groups and finally evaluated the BUT change accord ing to duration of wearing. The results were as follows. 1. The mean value of tear film break up time(BUT) was 8.64 +/- 3.91 seconds and 11.12 +/- 4.94 seconds in soft contact lens wearing group and normal control group respectively. 2. There was a statistically significant difference of BUT between each group(P<0.05). 3. There was statistically significant difference of BUT between more than 4 years of soft contact lens wearing group and less than 3 years of wearing gorup(P<0.05).

Free flaps have been widely used in lower leg reconstruction. However, in cases with extensive injury to the vessels as well as to the bone and soft tissues, and having only one intact major vessel in the lower leg(single vessel leg), careful selection of recipient vessels for the free flap transfer is mandatory for preventing further vascular compromise of the distal lower leg. The sural artery and its vena comitantes are frequently protected form externally harmful forces by the bulky surrounding gastrocnemius muscle and can be used as recipient vessles for free flaps without any detrimental influence on the vascularity of the distal lower leg. In our department, three latissimus dorsi muscle free flap were transferred with sural vessels as recipient vessels in the reconstruction of the single vessel legs. Except for one case of flap failure due to serious infection at the microvascular anastomoses site, all the other cases were successfully reconstructed without any necrosis of the gastrocnemius muscle or the distal leg. In addition, the sural vessels were easily accessed in any patient position and their caliber was similar to that of the vascular pedicles of the donor muscle flaps. In conclusion, the sural vessels can be another useful option in selecting recipient vessels for free flap transfer in the reconstruction of the single vessel leg.

The cardiac dimensions and functions were studied by analyzing simultaneously recorded M-mode echocardiograms and phonocardiograms in 24 cases of essential hypertension with no evidence of heart faliure, and also in 20 healthy adults for comparison. Thirteen hypertensives out of 24 had findings consistent with left ventricular hypertrophy on either routine chest roentgenograms or electrocardiograms or both(group II) and the remaining 11 had no such findings(group I). The posterior wall and septal thickness, and isovolumic relaxation time were significantly was increased even in the group I as well as in the group II. The isovolumic relaxation time was correlated well with the septal thickness in both groups. In contrast, a significant increase in left atrial and left ventricular systolic dimensions was noted only in the group II, and so was a significant reduction in the fractional shortening and mean velocity of circumferential fiber shortening. These findings suggest that the echocardiographic examination is useful in patients with essestial hypertension for the early dagnosis of the increased thickness of the posterior wall and the septum, and the abnormality during early diastolic relaxation of the left ventricle, prior to the appearance of the ventricular hypertrophy on the routine chest films amd/or electrocardiograms, and also that echocardiograms enable early detection of the systolic dysfunction of the hypertrophied left ventricle in the absence of apparent failure.

OBJECTIVES: Culture of sputum is apt to be contaminated through oral cavity and proximal airway. Therefore, identification of true etiologic agents by sputum culture is not always reliable. In order to differentiate the pulmonary infection from non-infectious disease and to identify the true etiologic agent of acute pulmonary infection, we used PSB(Protected Specimen Brushing) and evaluated the efficacy of PSB. METHODS: In 168 patients with acute febrile illness with pulmonary infiltrations(male 106, female: 61, mean age: 49.5+/-17.6), we performed PSB via a bronchoscope and compared the results along with blood culture and sputum culture. Protected specimen brush was introduced through biopsy channel of bronchoscope and was rotated within the purulent secretions. Tip of the brush was severed with aseptic technique and was immersed in 1cc of Ringer's lactate solution and vigorously mixed for 1 minute. The specimen was submitted for quantitative culture within 15 minutes and was regarded positive culture if colony forming units were above 10(3)/ml. RESULTS: Using PSB for the diagnosis of pulmonary infection, sensitivity was 71.1% and specificity was 84.296. PSB was helpful in identifing true etiologic agent among several potentially pathogenic organisms. Using PSB for the diagnosis of UAP (ventilator associated pneumonia), sensitivity was 72.4% and specificity was 100%. CONCLUSION: Use of PSB can be a helpful method for the diagnosis of pulmonary infection and identification of its etiologic agents.
