PURPOSE: To evaluate the prevalence of the opacification of paranasal sinuses and to correlate the prevalence and severity of the sinus opacification with presence of upper respiratory infection (URI) in infants and children using CT. MATERIALS & METHODS: We analyzed CT scans of 162 children aged under 16 who have no signs and symptoms of paranasal sinusitis. Both sides of maxillary and ethmoidal sinuses were evaluated. We scored from 0 to 3 according to the degree of soft tissue opacification of each sinus and then summed up the scores of each sinus. We divided the children into 5 groups according to their age. We paid particular attention to the following respects: 1) the prevalence of the opacification of the paranasal sinuses in each group; 2) the difference in the prevalence between the children with and without URI ;3) the correlation between the severity of the sinus opacification and the presence of URI. RESULTS: Of 162 children, one or more paranasal sinus opacification was noted in 76(47 %):31(65%) less than 1 year old;11(52%) between 1 and 2 years old;16(53%) between 2 and 6 years old ;15(28%) between 6 and 12 years old;and 3(33%) above 12 years old. In children less than 1 year old, no significant difference in the prevalence of the sinus opacification was found between URI-positive(71%) and URI-negative(58%) subgroups. In chilren between 1 and 12 years old, although the prevalence of the sinus opacification in URI-positive subgroups was much greater than that in URI-negative subgroup, statistically significant difference was noted only in children between 2 and 6 years old. As to the correlation between the severity of the sinus opacification and the presence of URI, these was a statistically significant difference in children between 2 and 6 years old and between 6 and 12 years old. CONCLUSION: Although the exact pathophysiology is not fully understood, the opacification of the paranasal sinuses is not an uncommon finding at CT in children without the signs and symptoms of sinusitis. We think that the clinical correlation is essential in determining the diagnosis and treatment plan in cases that the sinus radiographs or CT scans show the abnormal findings.

Several shorter-term alternatives for whole-day ambulatory monitoring of BP using Pressureometer III or standard sphygmomanometer were evaluated in 12 male hypertensive patients. Averages of BP reading at 8 AM once, consecutive 3 readings either by Pressurometer or manual, serial readings during 2-hr intervals of 8-10 AM and 2/4 PM were compared with that of 24-hr ambulatory, non-invasive BP readings. Both systolic and diastolic 2-hr Bp averages in the morning were correlated more strongly with 24-hour averages(r=0.91 and 0.91), than were those of the 3 readings(r=0.88 and 0.66) or single reading(r=0.49 and -0.35) alternatives. In conclusion, the average of serial readings obtained during 2-hr monitoring period from 8 to 10AM is a reliable predictor of 24-hr ambulatory BP and represents it more closely than the conventional single or multiple BP readings.

Primary breast lesions diagnosed by fine needle aspiration cytology, confirmed by histologic examination were analyzed by morphometry to evaluate the difference between benign and malignant lesions, and the methods obtaining the sample. Four size factors and 5 form factors were evaluated in 22 fibroadenomas and 20 carcinomas by image analyzer(Zeiss Ibas 2000) using the H-E stained slides. Nuclear size was significantly larger in the carcinoma cells than fibroadenoma cells both in the cytology and biopsy specimens, but the form factors were not significantly different. Both fibroadenoma and carcinoma cells were significantly larger in cytologic smear than histologic section. The cells in the cytology were more regular and round than those in histology, but not statistically significant. Fibroadenomas having cellular proliferation and atypism exhibited larger size and more irregular nuclei than non-proliferative fibroadenoma, but not statistically significant. Therefore nuclear morphometric analysis can be a helpful method to diagnose the questionable breast lesions and is a method appropriate for use as a quality control procedure in the fine needle aspiration cytology.

PURPOSE: To determine the head position that the superior border of the mandibular canal as well as mental foramen can be more clearly visualized in panoramic radiography MATERIALS AND METHODS: Ten dry mandibles were radiographed bilaterally using PM 2002 CC panoramic machine. A 20 mm thick aluminium filter was added to the slit collimator to obtain radiographs with acceptable density. The specimens were tilted by 2, 4, 6, 8, and 10 degrees downward with and without radiopaque markers. Radiopaque markers were inserted into the mandibular canals and the mental canals of each side of the specimens to serve as reference image when assessing the radiographs. The visibility of the mandibular canal and the mental foramen was estimated by 4 observers on all radiographs. The obtained results were analyzed statistically. RESULTS: Mandibular canals were significantly more clearly visible in the radiographs with 4 and 6 degree downward position on both sides (P<0.05). Mental foramens were significantly more clearly visible in the radiographs with 4, 6, and 8 degree downward on right side and 6 degree downward on left side (P<0.05). There was not significant difference between right and left sides. CONCLUSION: Panoramic radiographs with 4 to 6 degree downward tilting could be valuable in locating the mandibular canal as well as the mental foramen.

BACKGROUND: Aging is associated with increased cardiovascular risk and firmly established as a risk factor for the development of atherosclerosis. However the exact mechanism of age-related damage to the arterial wall and its relation to the atherosclerotic process are not well known.The endothelium plays an important role for the regulation of vascular tone and the endothelial function is impaired in the presence of risk factors early in the process of atherosclerosis. Assessment of endothelial function appears to be a valuable tool for the diagnosing and therapeutic monitoring of coronary artery disease. Anti-oxidants are known to improve endothelial dysfunction in atherosclerosis patients. The aim of this study was, (1) to evaluate the endothelial function in elderly, (2) to investigate whether vitamin C administration has benefit on the endothelial function in elderly. METHODS: The endothelial function was estimated using venous occlusion plethysmography(VOP) in 7 elderly and 7 young healthy volunteers. The strain guage was connected to plethysmograph to record the forearm volume change. A rapid cuff inflator was used to inflate the arm cuff to 40 mmHg instantaneuosly thus occluding venous return from the forearm. The measurement of forearm volume change was repeated for 7 times each stage. The change of the forearm blood flow(FBF) was measured with the acetylcholine infusion through brachial artery and also with intra-arterial vitamin C. RESULTS: Endothelium-dependent vasodilatation was significantly impaired in the elderly group compared to the young group(321 +/-17% in elderly group vs 509 +/-81%, mean+/-SEM) Forearm blood flow response to acetylcholine was significantly enhanced with inraarterial infusion of vitamin C in elderly group(321+/-17% in elderly group vs 78% in vitamin C) Coinfusion of L-NMMA, an inhibitor of nitric oxide synthase, blunted forearm blood flow response to acetylcholine. CONCLUSIONS: Even though the mechanisms leading to drpressed endothelial function in elderly remains to be elucidated, our study shows that vitamin C result in demonstrable improvement by a mechanism that is probably related to antioxidant activity.

Incisional metastases following surgery for cervical cancer are extremely rare. We report a case of a recurrence which occurred at a incisional site following radical hysterectomy and pelvic lymphadenectomy for squamous cell carcinoma of the cervix. The recurrence was found at the incisional site just below umbilicus that was not included for post-operative adjuvant radiotherapy. We performed wide local excision and postoperative adjuvant radiotherapy for 5 weeks. She has been under follow up until now, and there is no evidence of recurrence.

OBJECTIVE: This study was performed to evaluate the efficacy of treating of unruptured ectopic pregnancy by systemic and transvaginal local administration of methotrexate. METHODS: We reviewed the medical records of 32 patients who were treated with methotrexate from June 1995 to October 1999. Among the patients, 14 were treated by ultrasound-guided transvaginal local injection and 18 were treated by systemic intramuscular administration. Success rate of the treatment was examined for each group, and the cases of methotrexate failure were characterized and compared with the success group. RESULTS: The success rate was similar between the transvaginal (85.7%) and the systemic (77.8%) groups. There were no differences in initial serum hCG levels, size of gestational sac, fetal cardiac activity between the success group and failure group. CONCLUSION: The results of this study suggest that there is no difference in efficacy between systemic and transvaginal local methotrexate administration, and there are no useful parameters in identifying the risk for the failure of methotrexate treatment.
