Branchial cleft cyst is rarely encountered congenital neck disease. It is commonly believed that the branchial anomaly is persistance of remnant of the embryologic branchial apparatus. Among the patients visited Kyung Hee Medical Center with neck mass and inflammatory sign from January, 1980 to Aprial, 1994, we reviewed 26 cases of branchial cleft cysts confirmed by histopathologic findings with retrospective study on clinical aspects. The results are as follows: 1) There was no sex difference(14 male and 12 female), and most common between 2nd and 4th decade(21 cases, 80%). 2) Palpable mass was most common complaint(21 cases). In physical exam, the mass was non-tender, mobile and soft in most cases(over 80%). 3) The most common lesion site was anterior triangle in 15 cases. Along the SCM level, 21 cases were in upper 1/3, 2 cases in middle 1/3 and 3 cases in lower 1/3. 4) According to Bailey's classification, type II were 20 cases(76.9%), type I 5 cases(19.2%) and type III 1 case. 5) Among 28 cases, fistulous tract was found in 6 cases: one was complete type and 5 were incomplete type. 6) Among 26 cases before operation, 10 cases were diagnosed as branchial cleft cyst, 6 cases tuberculosis, 3 cases parotid tumor and 2 cases thyroglossal duct cyst. 7) Type of lining epithelium in histopathologic finding was stratified squamous epithelium in 22 cases(84.6%), mixed type in 4 cases(15.4%).

This paper was attemped to analize 55 cases of fiberoptic bronchoscopy during period of 3 years from Feb. 1978 till Feb. 1981 in Chung Ang University hospital. The results were as follow; 1) In age distribution; Most common age group was 5th decade (15 cases, 27.2%) and the other age groups showed relatively even distribution. 2) The ratio of male to female was 3 to 1. 3) The chief complaints were presented in following order; cough (52%), hemoptysis(25%), dyspnea(23.6%), chest pain(18%), chest disomfort(9%). 4) Direct smear of bronchoscopic aspiration material; Not found 33 cases (60%) were most common finding. In the founded bacteria Gram positive cocci 2 cases (3.6%), Gram negative cocci 2 cases (3.6%), Gram positive bacilli 1 cases (1.8%), Gram negativebacilli 2 cases (3.6%), mixed form 15 cases(27.2%) were presented. 5) Bacterial culture of bronchoscopic aspiration material; No growth 28 cases (50.9%) were most common finding. In the bacterial growth, alpha hemolytic streptococci 10 cases (18.2%), Neisseria group 7cases(12.7%), Klebsiella 2 cases (3.6%), Pseudomonas 2 cases (3.6%), mixed culture 6 cases (10.9%) were presented, 6) The diagnosis of bronchoscopic appearance, laboratory exam., and pathologic exam. of biopsed specimen were 21 cases (38.1%) primary carcinoma of bronchus, 8 cases (14.5%) pulmonary tuberculosis, 7 cases (12.7%) bronchitis in orders.

Background : To evaluate the efficacy of two methods of obtaining lung recruitment to reduce ventilator-induced lung injury(VILI). Methods : Fifteen New-Zealand white rabbits were ventilated in the pressure-controlled mode while maintaining constant tidal volume(10 ml/kg) and fixed respiration rate. Lung injury was induced by repeated saline lavage (PaO2<100 mmHg), and the pressure-volume curve was drawn to obtain Pflex. The animals were then randomly assigned to three groups and ventilated for 4 hours. In the control group(n=5), positive end-expiratory pressure(PEEP) less than that of Pflex by 3 mmHg was applied throughout the study. In the recruitment maneuver(RM) group(n=5), RM(CPAP of 22.5 mmHg, for 45 seconds) was performed every 15 minutes in addition to PEEP level less than Pflex by 3 mmHg This phrase is unclear. In the Pflex group, PEEP of Pflex was given without RM. Gas exchange, lung mechanics, and hemodynamics parameters as well as pathology were examined. Results : 1) Both the control and RM groups showed decreasing tendency in PaO2 with time. There was significantly decreased PaO2 at 4 hr compared to Ihr(p<0.05). But in the Pflex group, PaO2 did not decrease with time(p<0.05 vs other groups at 3, 4 hr). PaCO2 did not show significant difference among the three groups. 2) There was no significant difference in static compliance and plateau pressure. Mean blood pressure and heart rate also did not show any significant difference among the three groups. 3) The pathologic exam showed significantly less neutrophil infiltration in the Pflex group than in the control group(p<0.05). There was borderline significant difference in hyaline membrane score among the groups (p= 0.0532). Conclusion : Although recruitment maneuver of the injured lung may be important in decreasing VILI, it alone may not be sufficient to minimize VILI.
