2.Complete Reversal of Diffusion Restriction after Treatment of Traumatic Carotid-Cavernous Fistula.
Korean Journal of Neurotrauma 2017;13(2):171-175
A 15-year-old man presented with stupor following a motorcycle traffic accident. The patient was diagnosed with a traumatic left carotid cavernous fistula (CCF) with pseudoaneurysm of the left internal carotid artery. Brain magnetic resonance imaging (MRI) showed transiently restricted diffusion in the left centrum semiovale white matter and lower temporo-occipital area extending to the splenium of the corpus callosum, with high signal intensity on diffusion-weighted imaging. On the 35th day of admission, the patient had complete neurological recovery and a follow-up brain MRI revealed complete resolution of the lesions in the left centrum semiovale and splenium of the corpus callosum. These clinical and radiological features are highly suggestive of complete reversal of diffusion restriction after successful embolization of traumatic CCF.

BACKGROUND: Angiogenesis is an essential component of tumor growth and metastasis, and the vascular endothelial growth factor (VEGF) is one of the most important angiogenic factors. Several solid tumors produce substantial amounts of VEGF, which stimulates proliferation and the migration of ednothelial cells, therby inducing neovasculization by a paracrine mechanism. To evaluate the prognostic roles of angiogenesis and VEGF expression in patients with non-small cell lung cancer, the relationship between VEGF expression in tumor tissues, the clinicopathologic features and the overall survival rate were analysed. METHODS: Sixty-nine resected primary non-small cell lung cancer specimens were evaluated. The pareffinembedded tumor tissues were stained by anti-VEGF polyclonal antibodies using an immunohistochemical method to assess VEGF expression. RESULTS: In Forty-one patients (59%), the VEGF antigen was expressed weakly in their tumor tissue, whereas in twenty-eight patients (41%) the VEGF antigen was expressed strongly. The median survival time of the weak VEGF expression group was 24 months, and that of the strong VEGF expression group was 19 months. The three year-survival rates were 35%, 33%, respectively. The survival difference between both groups was not statistically significnat. CONCLUSION: Although results were not statistically significant, the strong expression group tended to poorer prognosis than weak expression group.

Tuberculosis is a common chronic infectious disease, although the spleen is an uncommon organ to harbor tubercle bacilli. Immunocompromised subjects are primarily prone to miliary tuberculosis and in them the spleen is invaded by Mycobacterium tuberculosis. Spleen tuberculosis is manifested commonly as a miliary form. The basic pathology is granulomatous inflammation. The CT finding of splenic tuberculosis are multiple, well-defined, roung or ovoid, low-density masses. Lymphadenopathy in the abdomen and mediastinum and pleural effusion can be found. We report two cases with tuberculosis of the spleen proved by computed tomography and histologic identification. One paitient did not improve following antituberculous medication, so splenectomy was performed. The other patient has been treated with antituberculous medication.

Aspergillosis refers to an infection with any species from the genus Aspergillus. Pleural aspergillosis is an uncommon disease with less than 30 cases having been reported in the literature since 1958. The etiologic factors for this aspergillosis are preexisting pulmonary tuberculosis, bronchopleural fistula, pleural drainage, and a lung resection. Surgical removal of the aspergillus-infected pleura is the main treatment for managing this disease. We have experienced two cases of pleural aspergillosis as a complication of a preexisting chronic empyema. The chest radiographs showed a pyopneumothorax with cavitation and the chest computed tomographic scans revealed a loculated pyopneumothorax with cavity formation suggesting a bronchopleural fistula. A grossly purulent fluid was extracted by thoracentesis, and Aspergillus fumigatus was grown from a fungus culture of the fluid. A decortication, wedge resection with a pleurectomy and a pleuropneumonectomy were performed. The postoperative course was satisfactory and the patients have been in good condition up to now. Pleural aspergillosis is a very rare and potentially life-threatening disease. However, good result without significant complication were obtained by treatment with systemic antifungal agents and surgical removal.

OBJECTIVES: Sleep problems has been consistently reported as a suicidal risk factor in adults and, recently, also in adolescents. In this study, dividing study subjects by the previous suicidal behaviors (suicidal vs non-suicidal), we compared the group differences of suicidal risk factors, and examined the possibility of sleep as a suicidal risk factor. METHODS: Study subjects were 561 (271 boys and 290 girls) from a community sample of high school students. Suicidal Risk Behavior Checklist, Center for Epidemiological Study-Depression (CES-D), Symptom Checklist-90-Revision (SCL-90-R) Anxiety and Aggression subscale, Pittsburg Sleep Quality Index (PSQI) were done. RESULTS: Forty six students (8.1%) reported previous actual self-harm behavior as a suicidal attempt, 181 students (32.4%) reported having suicidal thought only. Three hundred thirty four students (59.5%) reported no previous suicidal behavior (thought and attempt, both). Suicidal behavior group showed higher score on risk behaviors such as school violence, substance use and internet addiction. CES-D, SCL-90-R, PSQI showed significant group difference. Logistic regression analysis showed suicidal risk were significantly associated with depression, stress in suicidal risk factors and sleep latency, daytime dysfunction in PSQI. Analysis of variance (ANOVA) shows the most prolonged sleep latency and increased index of all PSQI components except sleep efficiency in suicidal attempt group. CONCLUSIONS: Sleep Problems had a strong association with the suicidal risk behavior in adolescents. Sleep problems, especially, prolonged sleep latency, daytime dysfunction might be important markers for suicidal behavior. Screening for sleep problems in adolescents are encouraged for the parents, school teachers, and related medical physicians.

PURPOSE: To report the first case of Waardenburg syndrome type 4 in Korea. CASE SUMMARY: A 3-year-old boy visited our clinic to have his abnormal right eye iris color checked. The patient had a previous operation Hirschsprung's disease. In addition, his older sister and aunt showed similar ocular findings. A general physical examination, hearing test, and fundus examination were performed. On examination, hypochromic heterochromic iridum, albinism of the posterior pole upon ipsilateral fundus, and dystopia canthorum were found. There was no abnormal finding in the hearing test. CONCLUSIONS: The patient showed hypochromic heterochromic iridum, dystopia canthorum, and albinism of ipsilateral fundus. He also had a family history of Waardenburg syndrome and had surgery associated with congenital megacolon. The patient was diagnosed with Waardenburg syndrome type 4.

We present a case of pulmonary artery catheter (PAC) placement through the right internal jugular vein, bridging vein and coronary sinus in a patient with previously unrecognized persistent left superior vena cava (LSVC) and diminutive right superior vena cava. A 61-year-old male patient was scheduled for mitral valve repair for regurgitation. Preoperative transthoracic echocardiography revealed dilated coronary sinus, but no further evaluations were performed. During advancement of the PAC, right ventricular and pulmonary arterial pressure tracing was observed at 50 and 60 cm, respectively. Transesophageal echocardiography ruled out intracardiac knotting and revealed the presence of the PAC in the LSVC, entering the right ventricle from the coronary sinus. Diminutive right superior vena cava was observed after sternotomy. The PAC was left in place for 2 days postoperatively without any complications. This case emphasizes that the possibility of LSVC and associated anomalies should always be ruled out in patients with dilated coronary sinus.

OBJECTIVES: We surveyed this study for knowing the relation within stress, depression and medical comorbidities, and finding the risk factors of major depression. METHODS: 1764 subjects were enrolled from Jan. 2009 to Dec. 2009 who visit Korea University Guro hospital healthcare center. The subjects answered the questionnaire of PSS(Perceived Stress Scale), PHQ-9(Patient Health Questionnaire-9) and the demographic data. We categorized them as the stress group, depressive group, medical comorbidity group and analyzed the correlation analyses and logistic regression analyses. RESULTS: 198 of 1764 subjects(11.8%) were applied to major depression, and the depressive group showed the higher mean stress score(23.19) and mean depression score(12.95) than the normal group. The total PHQ-9 score was increased by perceiving more stress, having more medical comorbidities. The subjects with female, visiting due to recent health problems, irregular exercise, current smoking, history of angina and cerebrovascular disease showed the increased risk of major depression. CONCLUSIONS: In this study, we find the PSS, PHQ-9 were valuable for mental health screening in healthcare center. As perceiving more stress and having more medical comorbidity, risk of major depression were increased. Accordingly the individuals with medical diseases or unhealthy lifestyle would need the mental health screen.
