1.Lumbar epidural venography

Journal of the Korean Radiological Society 1981;17(1):62-68

Myelography is widely used fo radiological diagnosis of herniated lumbar disc. But the diagnositc accuracy isonly about 84% with range of 67 to 100% with many cases of false negative and equivocal cases. In cases of extremelateral disc herniation and short cul de sac or wide epidural space, even quite a large disc herniation cannot bedetected to myelography. But with epidural venography these defects of myelography can easily be over come. 52cases of epidural venography were performed in department of Radiology of Capital Armed Forces General Hospitalduring the 20 months from May 1979 to Dec. 1980. And the findings were compared with those of myelography andoperative results. The results are as follows; 1. Of 52 cases, satisfactory opacification was obtained in 48 cases(92.3%). 2. Single vein injection was adequate for satisfactory opacification in 40 cases (76.9%). 3. There were 2cases of retroperitoneal extravasation of contrast media, but the patient recovered without difficulty. 4. Of 24cases operated, the venographic finding was confirmed in 21 casesa (87.5%) and of the 48 cases adequatelyopacified, there were only 3 cases of confirmed diagnostic error and so the error rate is only 6.25%. 5. Abnormalfindings of myelography were exactly reproduced on epidural venography and many cases with equivocal or normalmyelographic findings were accurately diagnosed with epidural venography. 6. In cases of total block, epiduralvenography was very useful for evalutaion of the caudal portion. So lumbar epidural venography is very useful notonly as an adjunctive method to myelography, but also as the first diagnostic procedure for herniated disc, forthe procedure is simple and the diagnostic accuracy is very high.

Many operative techniques for the repair of cleft lip nasal deformities have been reported. However, the situation with regard to nasal deformity is less satisfactorily understood than lip deformity, in which we have experienced significant improvement led by enhanced understanding of the total anatomic deformity of the primary cleft lip and the consequent refinement of surgical techniques. Our purposes in tip plasty are the restoration of nasal tip symmetry and correction of the obtuse angle of the cleft side nostril. Additionally, an inconspicuous scar is one of the merits of our method. The alar cartilage war exposed through both the alar rim and transcolumella incision, and then interalar loose connective tissue based superiorly was dissected and elevated. Cleft side alar cartilage was cross-hatched(Lipsett technique) on the deformed dome and relocated superomedially by a 4-0 vicryl fixation suture. The elevated intera1ar loose areolar tissue was used for augmentation of the alar dome. Conchal cartilage graft on cleft side dome and septoplasty were carried out in cases of specific necessity. We have performed this procedure in 19 patients, aged between 15 to 19. Average follow-up period was one year. Results have been rated good to excellent by patients and surgeons. There has been no recurrence of this deformity.

BACKGROUND: Oxygen concentrators are convenient to operate and economical for patients with chronic obstructive pulmonary disease (COPD). However, oxygen concentrators are not manufactured domestically and the COPD patients are currently treated with imported oxygen concentrators. To evaluate the efficacy and safety of domestically developed prototype oxygen concentrator before clinical application, the efficacy and safety of the domestic oxygen concentrator were evaluate by comparing with the imported one. Meterial and METHODS: The clinical tests were performed on 36 hyperhydrosis patients from April 1999 to August 1999. Domestic and imported oxygen concentrators were in turn applied to the same patient, who inspired oxygen for 60 minutes at a rate of 3 liters per minute through nasal prong. The oxygen concentrator, which was applied first, was randomly allocated. The arterial partial oxygen pressure (PaO2) was estimated to compare the efficacy; and the carboxy hemoglobin(COHb), pH, arterial CO2 partial pressure, pulse rate, blood pressure, and respiration rate to compare the safety before and after applying each oxygen concentrator. A student t-test was used to analyze the results. RESULTS: In respect to efficacy, the difference in the change of PaO2 before and after the application between two concentrators was not statistically significant. In respect to safety, the differences in the changes of COHb, pH, partial pressure of arterial CO2, pulse rate, blood pressure, respiration rate between two concentrators were also not statistically significant. CONCLUSION: The domestically developed oxygen concentrator, showed satisfactory efficacy and safety when compared with the imported one.
