Retinal arteriovenous crossing sites are important because they are generally the points at which. in branch retinal obstruction, a blockage of venous blood flow occurs. We evaluated retrospectively the cases of 54 patiens wIth a recent temporal branch retinal vein occlusion to determine the relative anatomic position of the obstructed vein in relation to its crossing artery. In 54 (100%) of 54 eyes, the artery lay antenor to the vein, toward the vitreous cavity. In the control corssing site, the artery lay anterior to the vein 41.3% (J9/46) of the time (p<0.01) The second control group, which was obtained by examining all of the first-and second-order, without BRVO, consisted of 103 crossing sites. In this second control group's artenovenous crossmgs, the arteries were situated anteriorly in 83 (80.6%) of 103 crossing sites (p<0.005). Our observation that the artery lies anterior to the vein at the all of BRVO crossing sites contributes further evidence that mechanical factors play a prominent role in the causing BRVO.

As noe of causes of epipora, anatomic abnormality of nasolacrimal duct, has been treated with dacryocystorhinostomy. Recently, the development of nasal endoscopy has made it easy to observe the intranasal sturcture. Thus, authors investigated the effect of nasal endoscopic dacryocystorhinostomy used in combination with microdrill and nasal endoscopy in those patients, with nasolcrimal obsturction at the time of dacryocystorhinography. From 1995 to April 1997, twenty-four patients have been treated by the intranasal dacryocystorhinostomy using the microdrill with follow up more than six months. All patients had been tested by preoperative intranasal exam and was measured radiologically preoperative`s size of lacrimal sac. The nasal endoscopy using microdrill had shown success rate of 83.3 percent and the surgerywas more successful as the size of preoperative lacrimal sac was larer without any complication. The formation of accurate bone foramen did not remarkably differ from the skin incisio at the time of operation. Therefore, dacryocystorhinostomy using microdrill can be useful for the treatment of lacrimal canal obstruction, especially with the proper operating equipment.

The purpose of this study is to compare the diagnostic accuracy and usefulness of three-dimensional CT, two-dimensional CT in case of blow-out fracture. Two-dimensional CT, three-dimensional CT images of twenty-four blow-out fracture and soft tissue incarceration. Two dimensional CT was superior to three-dimensional CT in evaluating orbital bone fracture and soft tissue incarceration. But, three-dimensional CT was more useful to identify of orbital bone fracture than two-dimensional CT in associated facial bone fracture. Coexamination with two-dimensional axial & three-dimensonal CT was useful not only in the detection of fracture but in the evaluation of soft tissue incarcerated blow-out fracture.

PURPOSE: The purpose of this study was to provide a basis for non-humidified low flow oxygen by nasal cannula and to provide a guide for consistent care in nursing practice. METHODS: A methodological study on the development of guidelines with experts' opinions on collected items, framing PICO questions, evaluating and synthesizing texts which were searched with the key words (low flow oxygen, nasal cannula, humidification of oxygen, guideline) from web search engines. RESULTS: Of the 45 researched texts on the web, 9 texts relevant to the theme were synthesized and evaluated. All patients with humidified or non-humidified oxygen therapy reported that they had no discomfort. CONCLUSION: The results indicate that there are no tangible grounds for patients' perceived differences between the humidified and non-humidified oxygen under 4L/min supplied by nasal cannula. with oxygen. Therefore, non-humidification oxygen therapy is strongly advised when suppling under 4L/min oxygen by nasal cannula (recommended grade A).

This review underscores the integration of cognitive behavioral therapy (CBT) as a critical component of psychiatry residency programs essential for the comprehensive training of residents. The core competencies psychiatry residents should develop as CBT therapists, including specific skills and knowledge domains, are outlined. In addition, the review addresses the necessary attitudes and techniques for faculty engaged in CBT supervision, providing insight into effective educational and supervisory strategies. The application of these principles in clinical training settings is discussed, highlighting their potential to improve the quality and effectiveness of CBT training in psychiatry residency programs.

Cowden's syndrome is a harmatomatous polyposis syndrome with characteristic mucocutaneous lesions and among the spectra of clinical disorders that has been attributed to germline mutations in the PTEN gene. Although Cowden's syndrome has rarely been reported, immunologic studies have revealed that patients with this syndrome have humoral and/or cellular immune abnormalities. We recently identified a 21-year-old woman with Cowden's syndrome who was diagnosed with candida esophagitis without a history of diabetes, carcinoma, or steroid therapy. We report the immunologic status of this patient and the relationship with candida esophagitis on the basis of a literature review.

Clear cell carcinoma of the ovary is a clinicopathologic entity with distinct morphologic characteristics and known to be associated with poor prognosis irrespective of stage and prognostic benefits of chemotherapy have not been evidently demonstrated. This represents 2-3.6% of all ovarian malignancies. From October, 1991 to January, 1998, nine patients with primary clear cell carcinoma of the ovary treated in the deptartment of Gynecology and Obstetrics, University of Ulsan, Asan Medical Center were identified, and clinical and histologic review(including architectural pattern, mitotic activity, nuclear grading) was performed retrospectively. The age of the patients ranged from 30 to 67 year(mean+S.D.; 46.0+11.8) and the mean parity was 1.2 (+1.3). Five(55.6%) of nine patients had elevated level of CA 125. The size of the tumors varied from 3 cm to 20 cm with the mean maximal diameter of 12.1 (+6.3) cm. The FIGO stages of the patients were IC(6 cases, 66.7%), IIC (2 cases, 22.2%) and IV(1 case, 11.1%). All patients except one were treated by total abdominal hysterectomy and bilateral salpingoophorectomy with or without omentectomy and pelvic lymph node dissection. All except two were received postoperative chemotherapy with regimens such as CEC (cyclophosphamide + epirubicin + carboplatin), TC(taxol + carboplatin), CC(cyclophosphamide + carboplatin) or CAP (cyclophosphamide + adriamycin + cisplatin). The mean follow-up duration was 14.6 (+ 8.6) months and 8 patients were free of disease and one patient with stage IV disease died of disease during postoperative chemotherapy(4 months after surgery).

PURPOSE: To report the expression of decorin and TGF-beta in partial myotomy of the extraocular muscle in rats. METHODS: Partial myotomy of the superior rectus muscle was performed on the right eye of 10 Sprague-Dawley rats followed by exposure of the left superior rectus muscle and a simple suture of the conjunctiva. The bilateral superior rectus muscle was obtained from all rats at 2 weeks postoperatively. The tissues were observed under light microscopy with hematoxylin-eosin, Masson's trichrome staining and immunohistochemistry. RESULTS: Histological examinations of the surgical area at 2 weeks after postoperatively showed irregularly concentrated fibrosis on light microscopy with hematoxylin-eosin and Masson's trichrome staining of the experimental eyes. Immnohistochemistry showed that expression of decorin was in the same location as TGF-beta in the experimental group. CONCLUSIONS: The expression of decorin was found in the healing process after partial myotomy of the extraocular muscle in rats. Immunohistochemistry showed that expression of decorin was in the same location as with TGF-beta.

The hypokalemic periodic paralysis is characterized by intermittent falccid paralysis of extremities with spontaneous recovery. It is rarely accompanied by cardiac arrhythmia, especially fatal ventricular tachycardia or torsades de pointes. We observed a 29 year old man, who had suffered from intermittent periodic paralysis and fatal ventricular tachyarrhythmia. He had the first episode of muscle weakness in his low grade of elementary school, which lasted for 20 -30 hours. Similar episodes of muscle weakness occurred 1 -7 times per year, especially after carbohydrate rich food. On admission to emergency room, his chief complaints were generalized weakness and chest tightness, serum potassium level was 1.6mEq/l, and four extremities showed Grade 0 motor weakness. His electrocardiography(ECG) showed Atrioventricular dissociation due to sinus tachycardia and accelerated junctional rhythm, intraventricular conduction distrubance. During intravenous potassium administration, ECG showed sustained ventricular tachycardia and cardiovascular collapse occurred. So we carried out resuscitation and cardioversion. After resuscitation, he recovered from cardovascular collapse and ECG showed sinus tachycardia. But during continuous monitoring ECG showed torsades de pointes with cardiovascular collapse. We carried out resuscitation and defibrillation repeatedly. Serum potassium level was 1.7 - 1.8mEq/L at that time. After successful resuscitation, ECG showed sinus rhythm, and his mental status was fully recovered. After he admitted to intensive care unit, paralytic attack and cardiac arrhythmia did not occurred any more. Serum potassium level was maintained between 3.9 -6.1lmEq/L during his hospital days. He was fully recovered but could not take any medications(e.g. acetazolamide, potassium supplying agent and antiarrhythmic drugs) due to severe gastrointestinal disturbances. During the 30 months of postdischarge period, he experienced three mild paralysis attacks, but they were not accompanied by chest tightness, palpitation or syncope.
