Primary intimal sarcoma of the pulmonary artery is a rare disease and there has been no report of any case originating from the pulmonary valve. Recently we experienced a 62 year-old female patient who had a primary intimal sarcoma of the pulmonary valve with distal metastasis. She was brought to medical attention due to exertional dyspnea facial edema productive coughing and general weakness for 1 month. Chest CT and echocardi-ography suggest an acute pulmonary thromboembolism or tumor. Exploration showed a large polypoid mass arising from the pulmonary leaflets and multiple masses on distal pulmonary arteries. We replaced the pulmonary valve and reconstructed the pulmonary artery. She received radiotherapy 1 month postoperatively and now 4 months after surgery she has begun receiving chemotherapy.

The stability and retention of mandibular complete denture have been a continuing problem for dentists and patients. Magnets have been investigated or used in clinical dentistry as retentive aids. The obvious advantages are that these attachments do not need spacial equipments or require frequent adjustment of replacement with use, and they likely transmit less lateral forces to the abutment. This articles discusses the scientific background and clinical application of high potency magnetic alloys in overdenture

Urinary cytology has become an essential element in the diagnosis and management of transitional cell carcinoma(TCC) of the urinary tract. It has the advantage of being noninvasive, inexpensive, and easily accessible. Besides that it can even detect malignancy when unsuspected at cystoscopy. We report a retrospective review of urine cytology in the diagnosis of 83 TCC cases that underwent 295 cytologic evaluation. All patients had biopsy-proven TCC of the bladder, ureter and renal pelvis. The overall inci- dence of the positive cytology cases was 66.2%. To define the cytologic features of tumor cells, we tried to use three cytologic gradings such as "grade 1", "grade 2", and "grade 3" according to the cytologic degree of anaplastic neoplastic cells. These cytologic gades of TCC were relatively well correlated with the histologic grade and tumor invasiveness. This result suggests that the recognition of characteristic cellular features of TCC can suspect the histologic grade and tumor stage. The false negative TCC cases were 78.9%. They showed severe inflammatory or bloody background and a few neoplastic cells. Therefore, a cautious approach for accurate interpretation, personal experience, and proper fixation and processing could expand the role of urinary cytology.

Hearing loss is a very common health problem throughout the world, although the number of hearing impaired individuals varies greatly in the countries. It is generally accepted that hearing impairment inevitably leads to a breakdown in communication and physical and mental health problems consequently. Nevertheless, few community based studies have been undertaken to examine both the mental and more general physical state of the hearing impaired patients. This study was conducted to evaluate the anxiety and depression in hearing impaired patients. Self-administered questionnaires including sociodemographic data were given to 336 subjects over the age of 18 years who visited the Health Management Center, Uijongbu St. Mary's Hospital for the routine health check up from January 1996 to April 1996 and three hundred seventeen samples (male: 197, female: 120) were selected. For the assessment of anxiety and depression we used Self-rating Anxiety Scale (SAS) and Self-rating Depression Scale (SDS) devised by Zung. And hearing impairment was evaluated using a Beltone Model 110 Audiometer. The results were statistically analyzed by ANOVA test and x(2) test. The results obtained were as follow: 1. The mean anxiety scores counted by SAS of 0-15dB HL (hearing loss) group (classified by the average loss in the better ear at 500, 1,000, 2,000Hz frequencies), 16-29dB HL group, 30-44dB HL group, more than 45dB HL group were 33.1+/-6.6 32.2+/-5.9, 41. +/-8.4, 42.8+/-6.0 respectively. And the mean depression Scores counted by SDS of 0-15dB HL group, 16-29dB HL group, 30-44dB HL group, more than 45dB HL group were 37.4+/-7.7, 37.2+/-7.2, 46.2+/-8.4, 48.6+/-8.6, respectively. The more than 30dB HL group showed significant high scores in SAS and SDS than the less than 30dB HL group (p<0.001). 2. The frequency of clinically significant anxiety disorder (SAS > or = 50) was 3.4% in less than 30dB HL group and 11. 1% in more than 30dB HL group. The difference between two groups was statistically significant (p<0.05). 3. The frequency of clinically significant depression disorder (SDS > or = 50) was 5.1% in less than 30dB HL group and 39.5% in more than 30dB HL group. The difference between two groups was statistically significant (p<0.05). 4. When several important interaction variables related to anxiety: and depression (such as age, sex, marital status, education level, economic status, occupation, religion) were stratified and we compared the groups between the more than 30dB HL and less than 30dB HL, most factors about anxiety and depression showed the significant differences in two groups. 5. Multiple logistic regression analysis revealed that hearing loss(p<0.05) predicted anxiety disorder (SAS> or = 50) and hearing loss(p<0.01), age(p<0.05) predicted depression disorder (SDS> or = 50). In conclusion, there was significant difference in anxiety and depression scores, between more than 30dB HL(in the better hearing ear) group and less than 30dB HL group. This study suggested that anxiety and depression should be considered as adverse effects of hearing impairment.

The Journal of Korean Academy of Prosthodontics 1997;35(1):244-249
Proper hygienic care of removable dentures is an important means of maintaining a healthy oral mucosa on denture wearers. Denture cleansing is often poor due to improper mechanical and the inefficient chemical cleansing of dentures. Dentists and patients should realize that microbial plaque on dentures may be harmful to both the oral mucosa and the patient's general health. This literature review was aimed to evaluate materials and methods for cleansing dentures and to discuss different means of keeping dentures plaque-free. A routine denture cleansing regimen should be designed to remove and prevent reaccumulation of microbial plaque and also to remove mucin, food debris, calculus, and exogenous discoloration. The combined use of chemical and mechanical cleansing is highly recommended for patients to clean their denture effciently.

Congenital dyserythropoietic anemia Type II (herditary erythroblatic multinuclearity with positive acidified serum test; HEMPAS) is characterized by binuclearity, multinuclearity, pluripolar mitoses, karyorrhexis of normoblasts, and the presence of abnormal antigens on the red cells. We experienced a case of HEMPAS in a 2 month old girl patient who had an intermittent fever, abdominal distention with palpable liver & spleen, and generalized jaundice. The blood analysis revealed anemia, and thrombocytopenia. Peripheral blood smear showed an averge of 6 mature normoblast per 100 leukocyte count. The red cells showed moderate anisocytosis, poikilocytosis, irregularly crenated, contracted cells and occasional spherocytes. The leukocytes showed relative lymphocytosis, and there were occasional villous lymphocytes. The marrow smear showed abnormality in erythroid series. About ten percent of the erythroblasts showed 2~7 nuclei or lobulated nuclei. The mitotic forms of the erythroid precursors were also increased in frequency. The M:E ratio was 1:3.2. Blood culture on this patient showed a pure growth of Coxiella burnetti. Medical treatment with Doxycycline and Rifampin was performed. After treatment, she became afebrile showing improved general condition with decreased size of liver & spleen. In spite of clinical improvement, she died suddenly 3 weeks after initial treatment.

This study was performed to investigate the influence of lateral guidance pattern and chewing pattern on masticatory muscle activity and occlusal contact pattern. Twenty-five patients with temporomandibular disorders and thirty students without temporomandibular disorders were selected for this study. Electromyographic examination and occlusal contact examination were performed simultaneously with Bio-Pak System(Bioresearch Inc.,U.S.A.) and T-Scan System(Tekscan Co., USA). The obtained results were as follows : 1. The EMG activity of masseter and anterior temporal muscle in patient group with canine guidance was higher than with non-canine guidance, but there was no significant difference(p>0.05). 2. The EMG activity of anterior temporal muscle in normal group with non-canine guidance was higher at preferred chewing side than at opposite side(p<0.05). 3. The EMG activity of masseter muscle was higher in normal group than in patient group (p<0.05). 4. The number of occlusal contact in patient group with canine guidance was higher than with non-canine guidance, but there was no significant difference(p>0.05). 5. The occlusal contact force at preferred chewing side was higher in patient group than in normal group(p<0.05).

PURPOSE: To evaluate the efficacy of the combination therapy of intravitreal bevacizumab injection and photodynamic therapy in neovascular age-related macular degeneration associated with large retinal pigment epithelial detachment. METHODS: A total of 13 eyes were reviewed, with 9 eyes diagnosed with definite choroidal neovascularization (CNV) and 4 eyes diagnosed with CNV or polypoidal choroidal vasculopathy (PCV) becausethe exact type could not be determined. Photodynamic therapy was performed within 1 week after bevacizumab injection according to indocyanine green angiography (ICGA). Additional bevacizumab injections were performed within a 4 to 6 week interval. Additional photodynamic therapy was performed within 4 months. RESULTS: The visual acuity on final examination had improved in 3 eyes (23.1%), was maintained in 7 eyes (53.8%), and decreased in 3 eyes (23.1%). The change of the PED before and after treatment showed regression in 5 eyes (38.5%), recurrence after regression in 2 eyes (15.4%), persistence in 4 eyes (30.8%), and retinal pigment epithelial tear in 2 eyes (15.4%). The maintained or improved visual acuity rate was 66.7% (6/9) and 100% (4/4) in the CNV and CNV or PCV group, respectively. CONCLUSIONS: The combination therapy in neovascular age-related macular degenerationassociated with large retinal pigment epithelial detachment is a viable alternative treatment in the stabilization and improvement of vision. However, further studies with long-term follow up and controlled studies with anti-vascular endothelial growth factor antibody monotherapy are required.
