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.

PURPOSE: Citron seed oil (CSO) has been reported to have high antioxidant activity. However, the composition and other biologically activities of CSO have not been reported. In this study, we confirmed the fatty acid composition of CSO, which may be beneficial to vascular disease and obesity. METHODS: We investigated the oil composition of CSO using gas chromatography coupled with mass spectrometry (GC-MS) analysis, and cytotoxicity was confirmed by Cell Counting Kit-8 (CCK-8) assay. Nitric oxide (NO) production in human umbilical vein endothelial cells (HUVECs) was measured using Griess reagent, and lipid accumulation and leptin secretion in 3T3-L1 cells were measured by Oil-Red O staining and commercial ELISA kit, respectively. RESULTS: GC-MS analysis indicated that CSO contains several components, including linoleic acid, oleic acid, palmitic acid, stearic acid, linolenic acid, palmitoleic acid, and arachidic acid. In physiological activity analysis, CSO did not induce cytotoxic effects in HUVECs and 3T3-L1 cells. Further, CSO significantly induced nitric oxide and leptin secretion as well as inhibited lipid accumulation. CONCLUSION: CSO increased NO release, inhibited lipid accumulation, and induced leptin secretion, suggesting it may be useful for the management of vessels and weight gain. Although further studies are required to investigate the safety and mechanism of action of CSO, our results show that the composition and physiological activity of CSO are sufficient for its use as functional edible oil.

Anomalous left pulmonary artery(pulmonary artery sling) is a congenital anomaly in which the vascular structure arises either from the posterior surface of the right pulmonary artery, or from the main pulmonary artery and courses to the left lung between the posterior surface of the trachea and the anterior surface of the esophagus. It may compress on the tracheobronchial tree causing significant symptoms on the part of the respiratory system such as dyspnea, stridor, or cyanosis. It is a rare condition leading to death in the first months of life, if it is not corrected. We present a case of pulmonary sling who was suffering from recurrent lower respiratory tract diseases, expiratory wheezing, and intermittent dyspnea since birth, thus she was treated for bronchial asthma. We confirmed the diagnosis with computerized tomography, especially with three dimensional reconstruction, which provided information regarding the spatial relationship between the anomalous pulmonary artery branch and the trachea and bronchi.

Authors came acoss a case of Behcet's syndrome involving cecum. The patient was a 33-year-old female. Her chief complaint was right lower quadrant pain, Colonoscopy revealed several ulcerations the base of which was covered by thick whitish coat, They were surrounded by mulitiple nodular masses. Endoscopic biopsy showed noaspecific ulceration. The patient had a history of aphthous ulceration of mouth and external genitalia. So she was diagnosed to have Behcets syndrome. She underwent right hemicolectomy with tetminal ilectomy. We report this case with literiature review.

In various autopsy series, overdiagnosis as well as underdiagnosis of pulmonary embolism has been reported. During the past decade, mortality rate has not declined despite advances in diagnostic methods. To evaluate the hypothesis that changes of hemodynamic parameters responded by mean pulmonary arterial pressure differences are of paramount importance to guide prognosis, experimental model of anesthetized dogs was used. Six dogs were anesthetized with 15 milligrams per kilogram of pentobarbital sodium, given intravenously and paralyzed with 2 milligrams of pancuronium bromide. 0.3 to 0.8 gram per kilogram of autologous blood clot was infused into the right atrium through a left external jugular vein. The dogs after embolization were divided into group A(mean pulmonary arterial pressure 33mmHg) and group B(mean pulmonary arterial pressure 43 mmHg). Each group of three dogs was monitored for a total of 4.5 hours. A 7F Swan-Ganz catheter was positioned and used to measure with fluid-filled transducer pulmonary capillary wedge pressure, mean pulmonary arterial pressure and mean right atrial pressure. Cardiac ouput was measured in triplicate by thermodilution and divided by weight to obtain the cardiac index. Blood gases, pH and saturation of arterial blood were measured. White blood cell and platerlets were counted in arterial blood. The results are as follows : 1) Changes in mean arterial pressure showed no significant differences between group A and group B following embolization. 2) Changes in mean pulmonary arterial pressure showed significant differences between group A and group B(p<0.05). 3) Changes in cardiac index showed significant differences between group A and group B after 45 minutes following embolization(p<0.05). 4) Changes in total pulmonary resistance showed significant differences between group A and group B after 45 minutes following embolization(p<0.05). 5) PaO2 showed significant differences between group A and group B after one hour following embolization(p<0.05), but arterial pH showed no significant difference. 6) Changes in mean pulmonary capillary wedge pressure, mean right atrial pressure and heart rates showed no significant differences between group A and group B following embolization. In conclusion, changes in mean pulmonary arterial pressure, cardiac index, total pulmonary resistance and PaO2 showed significant differences between group A and group B following embolization.
