In 38 patients with traumatic wound dehiscence after cataract surgery, we evaluated the causes and degrees of the injury, surgical methods of repair and the final visual outcome from Aug. 1993 to Apr. 1977. Among 38 patients, twenty-five were men and thirteen were women. In 34 patients, wound dehiscence occurred within one month after cataract surgery. The common causes of wound dehiscence were trauma by the finger or fist (9 patients) and by the contusion (7 patients). But in 16 patients, the exact causes of trauma were not identified. Accompanied ocular findings were prolapsed iris (29 patients) , hyphema (9 patients) , and dislocation of intraocular lens (7 patients). All patients received operations for wound closure, iris reposition, anterior vitrectomy, intraocular lens reposition or removal, and iris partial resection. At the end of follow-up, 27 patients achieved corrected visual acuity 20/40 or over. To prevent wound dehiscence after cataract surgery, we suggest that protective eye shield should be applied at least for a month after surgery.

The authors reviewed the charts of 128 patients(160 eyes) who underwent vitrectomy for the proliferative diabetic retinopathy from January 1993 to December 1995 and the results were analyzed in terms of visual efficiency. At the conclusion of the study, visual acuity improved in 96 eyes(60%), unchanged in 33 eyes(21%) and in 31 eyes(19%) became worse. Visual efficiency was increased from 11.9% preoperatively to 37.2% postoperatively in all patients. Patients under the age of 40 showed better results than the patients above the age of 40. The factors which affected the change in visual efficiency were age and preoperative intraocular conditions. The patients who had non-clearing vitreous hemorrhage without proliferative membrane revealed better prognostic results than the other patients. In 50 eyes (31.3%) of cases, maximal postoperative visual acuity was achieved in 4 weeks to 3 months after operation.

Tracheal bronchus is an aberrant bronchus that arises most often from the right tracheal wall above the carina and is the result of an additional tracheal outgrowth early in embryonic life. It; incidence ranges between 0.1 and 5%. This anomaly is usually diagnosed incidentally during bronchoscopy, bronchography or computed tomography. Occasionally, it represents the underlying etiology for chronic pulmonary disease, especially if it involves the right upper lobe and reflects an abnorrnal pulmonary clearing mechanism. The tracheal bronchus may be associated with other bronchopulmonary anomalies, tracheal stenosis, or Down's syndrome. Asymptornatic tracheal bronchus does not require any treatment. In case of tracheal bronchus associated recurrent right upper lobe diseases, tracheal bronchus therapy should include resection of the aberrant bronchus as well as the lob it supplies.

BACKGROUND: To decrease the risk of pulmonary aspiration of gastric contents, patients are routinely asked not to eat or drink anything for at least 6 to 8 hours before surgery. We studied to evaluate whether the volume and pH of gastric fluid immediately after induction of anesthesia is correlated with water ingestion. METHODS: Fifty patients, scheduled for elective surgery, were randomly divided into two groups. Control group(n=25) were fasted overnight and received no water. Experimental group(n=25) were fasted overnight and received 150 ml water approximately 2 hours before the induction of anesthesia. Gastric fluid was obtained via multiorifice gastric tube with the patient in three different positions. The volume of gastric fluid was recorded and its pH was measured. RESULTS: The gastric volumes were no differences between the two groups. The gastric pH values were significant differences. The incidence of patients with the high risk factors of gastric volume greater than 25 ml and pH less than 2.5 was decreased in experimental group. CONCLUSIONS: We concluded that surgical patients could be permitted to ingest 150 ml water approximately 2 hours before the induction of anesthesia.

This study was conducted in order to compare the biological activities of leaf and root water extracts of Smilax china L. (SC) by measuring the total polyphenol and flavonoid contents, anti-oxidant activity, inhibitory effect on alpha-glucosidase, and anti-inflammatory gene expression. The total polyphenol and flavonoid contents of SC leaf (SCLE) and root (SCRE) water extracts were 127.93 mg GAE/g and 39.50 mg GAE/g and 41.99 mg QE/g and 1.25 mg QE/g, respectively. The anti-oxidative activities of SCLE and SCRE were measured using the 1,1-diphenyl-2-picrylhydrazyl (DPPH) and 2,2'-azino-bis(3-ethylbenzothiazoline-6-sulfonic acid) diammonium salt (ABTS) radical scavenging activity assay and reducing power assay. Both SCLE and SCRE scavenged radicals in a concentration-dependent manner, and SCLE showed stronger radical scavenging activity and reducing power than SCRE; however, both SCLE and SCRE exhibited lower activities than ascorbic acid. Compared to the anti-diabetic drug acarbose, which was used as a positive control, SCLE and SCRE exhibited low alpha-glucosidase inhibition activities; nevertheless, the activity of SCLE was 3.7 fold higher than that of SCRE. Finally, SCLE caused significantly decreased expression of the LPS-induced cytokines, iNOS, and COX-2 mRNA in RAW264.7 cells, indicating anti-inflammatory activity. These results indicate that SCLE might be a potential candidate as an anti-oxidant, anti-diabetic, and anti-inflammatory agent.

Idiopathic restrictive cardiomyopathy is characterized by clinical and hemodynamic findings of restrictive cardiomyopathy in the absence of morphologic cause. The differential diagnosis between idiopathic restrictive cardiomyopathy and noncalcified constrictive pericarditis is difficult but the distinction is crucial because of the therapeutic implication. The diagnosis of idiopathic restrictive cardiomyopathy is aided by echocardiography and cardiac catheterization, cardiac magnetic resonance imaging. The patients should be approached systemically to differentiate from noncalcified constritive pericarditis.

DCRV is a rare cause of right ventricular outflow obstruction by anomalous muscle bundle at the level of sinus portion. The symptoms due to DCRV itself were mild inspite of significant pressure gradient over 90mmHg between proximal and distal chamber, and became severe by associated complication of bacterial endocarditis or aortic regurgitation in ventricular septal defect. In 12 cases(40%), right ventricular hypertrophy configuration in electrocardiogram was characteristic. Although R wave in V1 was tall, S wave in V6 and R wave in aVR were indistinctive. Those were very useful findings for diagnosis of DCRV which was thought to be possible only invasively. With operation prior to overt right ventricular faliure, the prognosis was good with only minor complication.

From march, 1983 to May, 1987, we experienced 17 patients of Marfan syndrome. The clinical profile and course of 17 patients of Marfan syndrome were reviewed. 1) Their ages ranged from 13 to 50 years with a mean age of 30 years and 16 patients were male and 1 patient was female. 2) musculoskeletal features were present in 14(88%) of the 16 examined. Ocular features were found in 5(42%) of 12 examined. Familial features were present in 7(47%) of 15 examined. 3) Among cardiovascular manifestations dissecting aneurysm was present in 10(59%) patients, aortic annuloectasia in 15(94%), MR in 4(24%) and MVP in 1(6%). 4) Modified Bentall operation was performed to 8 patients. Two of them died. The other 8 patients took a conservative medical therapy. Four of them died.
