RÉSUMÉ

OBJECTIVES: The purpose of this study was to compare psychological test profiles of psychiatric outpatients with high and low depression/suicide ideation and to identify predictor variables for depression/suicide ideation. METHODS: Component scores of the Personality Assessment Inventory (PAI) and Minnesota Multiphasic Personality Inventory-2 (MMPI-2) were compared using t-tests. Discriminant analysis was conducted for predictor variables of depression/suicide ideation. RESULTS: Regarding PAI profiles, somatic complaints (SOM), anxiety (ANX), anxiety-related disorder (ARD), depression (DEP), paranoia (PAR), borderline features (BOR), antisocial features (ANT), mania (MAN) drug problems (DRG) scores were significantly elevated in high depression and high suicide ideation groups. Concerning MMPI-2 profiles, the scores of hypochondriasis (Hs), depression (D), hysteria (Hy), psychopathic deviate (Pd), paranoia (Pa), psychasthenia (Pt), schizophrenia (Sc), social introversion (Si) were significantly elevated in these same groups. The PAI and MMPI-2 profile shapes were remarkably similar between high depression and high suicide ideation groups. Therefore, in terms of psychological profile, depression and suicidal ideation seemed to reflect the same construct. However, in discriminant analysis, significant predictors for depression were found to be Pt and D Sc from MMPI-2, while those for suicide ideation were found to be Pa and Sc, suggest subtle differences. CONCLUSION: The superficial characteristics of depression and suicide ideation groups reflected by the psychological test profiles seemed similar, but the determining factors may differ. Thus, the psychological interventions for these two groups may have to follow different routes considering these subtle differences.

RÉSUMÉ

Artemisia argyi is used as a health supplement, tea, and food source in Korea. This study aimed to evaluate the effect of Artemisia argyi (AA) and its active compound, dehydromatricarin A (DA), on the attenuation of airway inflammation in a murine model of lipopolysaccharide (LPS)-induced acute lung injury (ALI). The C57BL/6 mice were administered AA (50 mg/kg or 100 mg/kg) and DA (10 mg/kg or 20 mg/kg) by oral gavage from day 0 to 7 days and LPS treated by intranasal instillation 48 hours before the sacrifice. The treatment of AA and DA markedly decreased inflammatory cells in the bronchoalveolar lavage fluid (BALF) compared with that in ALI-induced mice, which was accompanied by a significant reduction in the levels of tumor necrosis factor (TNF)-α and interleukin (IL)-6 in BALF. Furthermore, the administration of AA and DA clearly decreased inducible nitric oxide synthase (iNOS) expression and nuclear factor kappa B (NF-κB) phosphorylation in comparison with that in the ALI-induced mice. The histological examination of the lung tissue revealed that the administration of AA and DA suppressed the inflammatory cell infiltration into the peribronchial and alveolar lesions induced by LPS instillation. Collectively, our results indicated that AA and DA effectively decreased the airway inflammatory response induced by LPS instillation. Therefore, AA and DA may offer a potential therapy for airway inflammatory disease.

RÉSUMÉ

OBJECTIVES: Endonasal dacryocystorhinostomy (DCR) is a well-established treatment method in patients with nasolacrimal duct obstruction. However, there are a few reports about the overall management of failed endonasal DCR. We investigated the causes and management strategies of failed endonasal DCR. METHODS: This retrospective review included 61 patients (61 eyes) who had undergone revision surgery by the same surgeon after failed endonasal DCR between January 2008 and December 2012. The appropriate revision method was determined after analysis of the etiology of failure by the fluorescein dye disappearance test, nasal endoscopy, lacrimal irrigation, and probing. The criteria for success of the revision surgery were defined by the passage of fluid without resistance upon lacrimal irrigation and normalization of the tear meniscus height. RESULTS: The mean duration between the primary endonasal DCR and revision surgery was 15.3 months. The average follow-up period after revision surgery was 12.2 months. The most common cause of endoscopic revision surgery was membranous obstruction. Endoscopic revision surgery was performed in 48 patients, while lacrimal silicone tube intubation under endoscopy was performed in 13 patients. The most common indication for lacrimal silicone tube intubation was functional epiphora. The overall success rate of the revision surgery was 89%. CONCLUSION: The most common cause of failed endonasal DCR was membranous obstruction. When patients with failed endonasal DCR presented at the clinic, it is important to identify the cause of the failure. Revision surgery could increase the final success rate of endonasal DCR.

RÉSUMÉ

PURPOSE: To identify the risk factors of retinal breaks in patients with symptoms of floaters and to determine the associations between those risk factors and retinal breaks. METHODS: A retrospective chart review of patients who visited with the symptom of vitreous floaters between July 2012 and October 2012 was performed. Patient information, such as age, sex, symptoms (e.g., multiple floaters and flashing), duration of symptoms, refractive error, and complete eye examination were recorded. The patients were divided into 2 groups: the control group had symptoms of floaters with no retinal breaks and the retinal breaks group had symptoms of floaters with retinal breaks. The chi-square test and univariate logistic regression were used for statistical analysis. RESULTS: A total of 1744 eyes were examined in this study, including 1706 eyes in the control group and 38 eyes in the retinal breaks group. Univariate analysis revealed that patients with high myopia and multiple floaters showed increased risk of retinal breaks by 3.4 and 4.4 times, respectively, when compared to patients with a single floater alone. Lattice degeneration and vitreous or retinal hemorrhage increased the risk of retinal breaks by 10.8 and 37.5 times when compared to eyes that did not have lattice degeneration or vitreous or retinal hemorrhage. During the follow-up period after laser photocoagulation, a new retinal tear was found in 2 patients (2/38, 5.3%). CONCLUSIONS: Vitreous or retinal hemorrhage, lattice degeneration, multiple floaters, and high myopia are risk factors of retinal breaks in patients with the symptom of floaters. Therefore, it is important for ophthalmologists to be aware of these risk factors and the patients at risk should be encouraged to attend follow-up examinations.

RÉSUMÉ

PURPOSE: To evaluate whether the radiological and clinical results of treatment with intertrochanteric/subtrochanteric (ITST) nail on unstable intertrochanteric fractures are combined with comminution of the greater trochanter or not. MATERIALS AND METHODS: We reviewed the results on 210 cases of unstable intertrochanteric fractures (grouped 88 patients with comminution of greater trochanter [GT] and 122 patients without comminution of GT) treated with ITST nail from January 2007 to October 2011, which was to be followed-up for more than 12 months. RESULTS: The mean union time was 15.2 weeks in the study group (combined with comminution of GT). The mean union time was 14.7 weeks in control group (no comminution of GT). The lag screw sliding was 8.7 mm in the study group and 7.2 mm in the control group. Changes of neck-shaft angle was 4.2degrees in study group and 4.1degrees in control group. Tip-apex distance was 17.4 mm in study group and 16.4 mm in control group. The complications were 4 cases in each study group and control group. The clinical results checked by Skovron recovery scores decreased similarly in both groups, 73.7% in study group and 76.5% in control group. There were no significant differences in both groups according to radiological and clinical results. CONCLUSION: The comminution of great trochanter does not affect on the radiological and clinical results when using the ITST nail of unstable intertrochanteric fractures.

RÉSUMÉ

PURPOSE: To evaluate patients' self-recognition of reduced visual acuity due to recurring macular edema in retinal vein occlusion. METHODS: A retrospective review of medical records of patients who were diagnosed with recurring macular edema secondary to retinal vein occlusion was performed. The proportion of patients who recognized reduced visual acuity due to the recurrence of macular edema and who visited the hospital before the scheduled follow-up date was determined. Parameters including age, sex, diagnosis, visual acuity before recurrence of macular edema, and extent of visual acuity reduction due to recurrence of macular edema were compared in patients who recognized a reduction in visual acuity and those who did not. The proportion of patients who visited the hospital promptly was also determined. RESULTS: Forty eyes of 40 patients were included in the analysis. Sixteen and 24 patients were diagnosed with central retinal vein occlusion and branch retinal vein occlusion, respectively. Twenty-one patients (52.5%) recognized reduced visual acuity due to recurring macular edema. These patients were younger (59.2 +/- 7.6 vs. 64.8 +/- 9.4 years, p = 0.046), had better visual acuity before recurrence of macular edema (0.52 +/- 0.48 vs. 1.02 +/- 0.46, p = 0.002), and exhibited a greater reduction in visual acuity after recurrence of macular edema (0.34 +/- 0.24 vs. 0.14 +/- 0.13, p = 0.003). Only four patients visited the hospital before the scheduled follow-up date, and all of these patients lived relatively close to the hospital. CONCLUSIONS: For prompt treatment of recurring macular edema, more intensive education about the self-estimation of visual acuity is necessary, particularly for elderly patients who have relatively poor visual acuity. In addition, a simple and easy way to identify the recurrence of macular edema at the local clinic should be established for patients who live relatively far from the hospital.

RÉSUMÉ

PURPOSE: To evaluate long-term outcome of foveal tissue elongation after macular hole (MH) surgery. METHODS: This retrospective, observational case series was performed on patients who underwent MH surgery and were followed-up more than 12 months. Distance between the parafoveal edge of the outer plexiform layer (OPL) was defined as the inter-OPL distance and measured using optical coherence tomography images at 5 to 8 months postoperatively and at the last follow-up. The horizontal and vertical inter-OPL distances were compared between the 2 defined time points. In addition, further elongation of the foveal tissue in certain directions was defined as asymmetric elongation and was compared between the defined time points. RESULTS: The early and late postoperative examination was performed at 6.3 +/- 1.1 (mean +/- standard deviation) months and 22.7 +/- 7.8 months, respectively. The horizontal inter-OPL distance was 552.3 +/- 130.5 microm and 502.8 +/- 139.3 microm at the defined time points, respectively and the vertical inter-OPL distance was 478.9 +/- 107.2 microm and 447.5 +/- 107.1 microm, respectively. Both horizontal and vertical inter-OPL distances were significantly shortened at the last postoperative examination (p < 0.001, p = 0.002, respectively). The degree of asymmetric elongation was 10.8 +/- 6.5% and 11.8 +/- 7.9% at the defined time points, respectively, and was not different between the defined time points (p = 0.426). CONCLUSIONS: The long-term shortening of foveal tissue after MH surgery without progression of asymmetry may partially contribute to the long-term recovery of visual function after MH surgery.

RÉSUMÉ

PURPOSE: To evaluate the 12-month outcomes of anti-vascular endothelial growth factor (VEGF) treatment for patients with retinal angiomatous proliferation (RAP). METHODS: Retrospective review of medical records was performed for 33 patients (33 eyes) who were diagnosed with RAP. All patients were initially treated with three consecutive intravitreal anti-VEGF injections after diagnosis. Additional treatment was performed when the recurrence of exudation was noted. The best-corrected visual acuity (BCVA) was measured before the first injection and at 3, 6, and 12 months after the first injection. The value measured before the treatment was compared with those measured after treatment. RESULTS: The patients received an average of 4.2 +/- 1.7 intravitreal anti-VEGF injections during the 12-month follow-up period. The logarithm of minimal angle of resolution (log MAR) values of BCVA before the first injection and at 3, 6, and 12 months after the first injections were 0.76 +/- 0.49, 0.55 +/- 0.35, 0.67 +/- 0.41, and 0.70 +/- 0.50, respectively. BCVA was significantly improved at 3 and 6 months (p or =2 log MAR lines of improvement) BCVA. CONCLUSIONS: Anti-VEGF therapy was found to be beneficial in both normalizing macular thickness and in improving or maintaining visual acuity in the majority of patients with RAP.

RÉSUMÉ

PURPOSE: Nitric oxide (NO) is synthesized from the amino acid L-arginine by nitric oxide synthase (NOS) which exists as three isoforms, the calcium-dependent endothelial NOS and neuronal NOS, and a calcium-independent inducible NOS. NO has been studied in a variety of human cancers and is implicated in both tumor promotion and inhibition. NO cause p53 mutation in human cells and mutations of p53 are the most common genetic abnormality yet found in human cancers. Aims of this study is to investigate the correlation of iNOS and p53 expression in colorectal cancer, and to evaluate its clinicopathological siginificance with the expression of these proteins. METHODS: 125 patients, who received curative resection of colorectal cancer from 1992 to 1996, were analyzed retrospectively. The monoclonal antibody to the iNOS (Transduction Laboratories.), the monoclonal antibody to the mutant p53 (Dako Co.) were used for the immunohistochemical analysis. Normal colorectal tissue were assayed in 45 cases. The relationship between mutant p53 and iNOS was investigated. RESULTS: When iNOS expression were detected in specimens, positive rate of mutant p53 were 72.4%. When mutant p53 expression were detected in specimens, positive rate of iNOS expression were 65.8%(P<0.05). Positive rate of iNOS, mutant p53 in tumor size were 51%, 56% below 4 cm and 60%, 63% in 4~8 cm and 47%, 67% above 8 cm. Positive rate of iNOS, mutant p53 in Dukes' stage were55%, 55% in stage B and 56%, 67% in stage C. Positive rate of iNOS, mutant p53 in histologic differentiation were 55%, 55% in well-differentiation and 61%, 66% in moderate differentiation and 35%, 48% in poor-differentiation. There was no difference in each Dukes stage between iNOS expression or p53 mutation and postop five year survival rate. Positive rate of iNOS, mutant p53 in normal tissue were 22%, 32%. CONCLUSION: The prevalence of iNOS expression and p53 mutation has been found in exceeding 50% of cases. There was a significant correlation between iNOS expression and p53 mutation in colorectal cancer. No correlation was found between iNOS expression or p53 mutation and clinicopathologic parameters.

RÉSUMÉ

PURPOSE: Non-specific ulceration of colon is a rare disease of unknown etiology. To establish correctly the diagnosis of nonspecific colon ulcer preoperatively is difficult, but with more wide spread use of colonoscopy and complementary diagnostic aids, this lesion may be accurately diagnosed more often. The presentating symptoms were mainly lower abdominal pain, which mimic such conditions as acute appendicitis, diverticulitis, intestinal obstruction, and colon cancer. If its serious complications (perforation, abscess formation, or uncontrolled bleeding) were developed, resection of ulcerated segment or more extensive colectomy was recommended. The purpose of this study was to establish correctly the diagnosis of nonspecific colon ulcer preoperatively and to identify definitive treatment of complicated colon ulcer. METHODS: 6 cases, surgically treated as non-specific colon ulcer at Chosun University hospital from January 1995 to December 1999 were studied retrospectively. RESULTS: The ages of the patient ranged from 35 to 70 years; the ratio of male to female is 2: 1. The main clinical symptoms were abdominal pain (6 cases), nausea and vomiting (4 cases), hematochezia (3 cases), constipation (2 cases) and palpable mass (1 case). The preoperative diagnosis was generalized peritonitis (2 cases), colon cancer (2 cases), acute appendicitis (1 case), mechanical obstruction (1 case). 3 cases had past medication history, one was anti-hypertensive drug and the two were nonsteroidal anti-inflammatory drug. The preoperative diagnostic study were simple abdomen (6 cases), abdominal CT (6 cases), colon study (3 cases), abdominal sonograph (4 cases) and selective angiogram (1 cases), The location of ulcer were cecum (2 cases), sigmoid colon (2 cases), transversecolon (1 case) and descending colon (1 case). The methods of operation were hemicolectomy (3 cases), segmental resection (1 case) and anterior resection (2 case). There was one death, but 5 cases were completely recovered. CONCLUSIONS: Non-specific ulcer of the colon is not detected until complicated by bleeding, perforation, or obstruction. The patient who has chronic abdominal pain and rectal bleeding can be diagnosed preoperatevely by colonoscopy and colon study. The recommended therapy of complicated cases is resection of the ulcerated segment or more extensive colectomy. Non-specific colonic ulcer should be suspected as one of colonic disease in the patients with complications.

RÉSUMÉ

Microcystic meningioma, a distinct morphological variant of meningiomas, is histologically characterized by a vacuolated appearance with multiple cystic spaces lined by vacuolated or stellate-shaped tumor cells. This unusual variant was originally described by Masson, who labeled it "humid". The clinical and morphological findings point toward a benign course. And these unusual morphological variants of meningioma are potentially curable tumor. But there is no definitive method for preoperatively differentiating microcystic meningioma from the malignant glioma. We report a case of microcystic meningioma occurring in the left frontal area of 74 year old woman, with malignant clinical nature.

RÉSUMÉ

Seasonal and climatic variations have been linked to the occurrence of some types of cerebrovascular disease. However, the conditions that lead to intracranial aneurysm rupture are not known. The purpose of the present study was to determine whether predisposing factors are more related to intracranial aneurysm rupture and to determine relation of the stressful condition to intracranial aneurysm rupture. In order to determine the predisposing factors, the authors have examined the relationship between seasonal variation and predisposing factors of cerebral aneurysm. The author investigated activities of the patients and events as well as diurnal and seasonal variations in the onset of subarachnoid hemorrhage(SAH) in 336 consecutive patients. The results showed that the onset of SAH was associated with working in 11.0%, defecation and/or urination in 8.3%, sleeping in 6.9% and 4.2% walking. Hypertensive patients in aneurysmal rupture was 36.0%. Subarachnoid hemorrhage occurred during stressful events in 36.3% of the patients, during nonstreneous events in 34.8% and during rest or sleep in 9.8%. The activities or events preceding subarachnoid hemorrhage were not known in the remaining 18.8%. Men were more likely to have suffered their hemorrhages during stressful events than women(47% vs 30%). Peak times of intracranial aneurysm rupture usually occurred from 6 to 11 A.M.(36.0%) and from 4 to 6 P.M.(20.5%). The seasonal variation of the onset of SAH showed the incidence to be slightly higher in winter than in any other seasons. We concluded that the occurrence of subarachnoid hemorrhage display seasonal and diurnal variation. And the precipitation of aneurysmal rupture have two important factors; increased arterial blood pressure and decreased cerebrospinal fluid pressure around the aneurysm. Also, the onset of the subarachnoid hemorrhage is related to the physiological circadian periodicity of blood pressure, climatic change and stressful events.
