Waardenburg syndrome is a very rare auditory-pigment syndrome with autosomal dominant inheritance. In his first report in 1951, Waardenburg characterized this syndrome as dystopia canthorum, a high broad nasal bridge, synophrys[confluent eyebrows], heterochromia iridid, a white forelock or early graying, and sensory neural deafness. We observed a case of Type 2 Waardenburg syndrome with openangle glaucoma and, therefore report with literature review.

PURPOSE: It is reported that 65% of diabetic male patients over 60 of their age are impotent. However, there is no report concerning the effect of serum glucose control on erectile dysfunction in diabetic patient. This study was performed to evaluate the effects of serum glucose control on erectile dysfunction. MATERIALS AMD METHODS: The development of Diabetes mellitus was defined that the serum glucose level was above 200mg/dL in random test at 25 weeks. We designed the experimental specimen into 3 groups; group I: diabetic OLETF (Otsuka Long Evans Tokushima Fatty) rats without blood sugar control (n=10), group II: diabetic OLETF rats with blood sugar control with 4U insulin subcutaneous injection daily from 26 to 46 weeks (n=10), group III: diabetic OLETF rats with blood sugar control with 10U insulin subcutaneous injection daily from 26 to 46 weeks (n=10). We estimated the collagen content of penile tunica albuginea with the scanning electron microscopy and observed the endothelial layers of corpus cavernosum with the transmission electron microscopy in each group. RESULTS: The serum glucose level was 249 +/- 4.1mg/dL, 234 +/- 2.7mg/dL, 215 +/- 3.0mg/dL respectively in group I, II, III, and decreased in order of group II, III. The differences among groups were statistically significant (p<0.05). The thickness of collagen bundles of penile tunica albuginea was 0.98 +/- 0.1 micrometer, 0.94 +/- 0.3 micrometer, 0.92 +/- 0.1 micrometer respectively in group I, II, III, and decreased in order of group II, III. The differences among groups were statistically significant (p<0.05). The endothelial layers of corpus cavernosum were decreased in II, III. CONCLUSIONS: The serum glucose control in diabetic rats decreases the collagen con tents in penile tunica albuginea and the endothelial layers of corpus cavernosum.

Dissecting aortic aneurysm is an emergency condition which requires prompt diagnosis and management. From January 1992 to December 1996, 54 patients were admitted to our department. Patients were categorized according to the Stanford classification of aortic dissection and investigation of the clinical records utilized the retrospective method. Male constituted the majority, according for 38(70.4%) of the total number of patients, whereas females accounted for 16(29.6%). Mean age was 52.1+/-2.2 years old (range:25~82). Clinical findings included chest pain in 46 cases(85.2%), renal failure in 11(20.4%), aortic insufficiency in 10(18.5%) and stroke in 9(16.7%). Predisposing factors were hypertension in 48 cases(88.9%), Marfan's syndrome in 5(9.3%) and diabetes mellitus in 1(1.8%). 21 patients(type A:12, type B:9) underwent surgical treatment. There were three(2 in type A and 1 in type B) deaths in the surgical treatment group and nine(5 in type A and 4 in type B) deaths in the medical treatment group. These results reflect our current policy in the management of dissecting aortic aneurysm.

OBJECTIVES: Cognitive psychological models propose that auditory hallucinations arise from a problem with monitoring one's auditory verbal imagery. Most auditory hallucinations are derogatory in content and accompany negative emotions. If auditory verbal imagery plays an critical role in the pathogenesis of auditory hallucination, it must be influenced by negative emotions. This study was aimed at understanding the influence of negative emotions on the development of hallucinations by investigating the way by which negative emotions have influence on cortical activity induced by auditory verbal imagery. METHODS: For both normal subjects and patients with schizophrenia, quantitative electroencephalography(Q-EEG) was applied during the auditory verbal imagery tasks using a two word list. The one word list accompanied negative emotion and the other accompanied neutral emotions. The difference of EEG activity between two tasks was compared by paired t-test. WE also compare the difference of the influence of negative emotions between normal subjects and patients with schizophrenia. RESULTS: In normal subjects, amplitude of beta wave was increased in temporal area such as TCP1, and, the amplitude of theta frequency wave was decreased in right hemisphere such as FP2, F4, C4, CP2, P4, But, in the schizophrenia group, there were no significant differences. CONCLUSION: These results may suggest that auditory verbal imagery with negative emotion requires more activation in left temporal area, but, appropriate activation may not achieved in schizophenia patients. So, the possibility that the resultant disturbance of verbal self monitoring may be related to auditory hallucination is suggested in this study.

OBJECTIVE: Amniocentesis for the diagnosis of prenatal genetic abnormalities is now the standard care for women who are at special risk. because the application of population-based maternal serum screening to prenatal diagnosis is now widespread, we can estimate the trend change of amniocentesis indications. METHODS: Four hundred twenty eight women who were attending the antenaltal clinic of Hanyang University Hospital had a amniocentesis between January 1992 and June 1997. The result were analyzed in reference to indication of amniocentesis, gestational age, pregnancy outcome and karyotype. RESULT: The major indications were abnormal maternal serum marker(53.3%), advanced maternal age(23.8%), previous fetal chromosomal anomaly(7.9%) and the most common age distribution at amniocentesis was 25-29 years(37.9%). The pregnancy outcome was full-term delivery(84.2%), preterm delivery(13.7%), spontaneous abortion(1.4%) and termination of pregnancy(0.7%). Among the 33 cases(7.7%) of abnormal karyotype, structural aberration was 21 cases(4.9%) and numerical aberration was 12 cases(2.8%). Among the numerical aberration, six cases of trisomy 21, five cases of Klinefelter syndrome, and one case of Turner syndrome were found. Among the structural aberration, insertion was most common(nine cases), and seven cases of inversion, four cases of translocation and one case of deletion were found. CONCLUSION: This is a report of genetic amniocentesis, with analysis of the indication, gestational age, karyotype results and complication.

BACKGROUND: Trauma is the third leading cause of death, irrespective of age, and the leading cause of death in persons under 40 years of age. Computed tomography (CT) is an effective technique in the initial emergent evaluation of the abdomen and head following blunt trauma. Most chest indies are not seen on conventional chest radiography, or may be underestimated. But routine use of CT in the initial emergent evaluation of chest trauma is controversial. CT, however, has been shown to be useful in the diagnosis of unsuspected chest injuries and in directing therapeutic interventions. This review discusses the efficacy of emergent CT in patients with blunt trauma on the chest. METHODS: To evaluate the efficacy of CT of the thorax, a retrospective study comparing early thoracic CT scanning with initial chest roentgenogram(CXR) was carried out on 121 patients with blunt trauma on the chest. The interval between CXR and CT was less than 1 hour. RESULTS: Among 121 patients, 42 patients had normal initial chest roentgenogram in whom 19 patients showed normal CT findings. Sensitivities of diagnosing pneumothorax and pleural effusion by CXR were low (49.3%and 45.1%respectively), whereas 65.7% (44/67) of patients had thoracostomy only by CXR. CONCLUSIONS : Although sometimes abused in patients with chest trauma, CT of the thorax is an effective method of detecting thoracic injuries and provides accurate information regarding their pattern and extent in the initial emergent diagnosis.
