1.The Effects of Bleopuncture Technique in the Treatment of Warts.
Korean Journal of Dermatology 1994;32(3):446-450
BACKGROUND: The warts may promptly return despite being treated with a myriad of destructive methods. The most successful treatment has been the intralesional injection of bleomycin sulfate, but unplessant side effects caused by the difficulty of infiltrating only the wart tissue have limited its use. OBJECTIVE: Our purpose was to determine the effects of bleopunciure technique in the treatment of warts. METHODS: We performed a multiple puncture technique using a 25 gauge hypodermic needle to introduce bleomycin hydrochloricle into warts. RESULTS: This technique resulted in elimination of 91.4% of a random series on 105 warts after a single treatment. Recurrence and side effects were not observed during a 1 year follow-up period. CONCLUSION: We experienced a superior technique for introducing Heomycin into the wart, which has resulted in the cure of a signficant number of warts following a sing treatment.

Reversible posterior leukonecephalopathy syndrome RPLS), a neurologie disorder associated with evidence of posterior cerebral edema on neuroimaging studies, has been described in both adults and children. Conditions predisposing to RPLS include malignant hypertension, renal dysfunction, toxemia of pregnancy, interferon therapy, and the use of immunosuppressive agents. When associated with acute hypertension, RPLS typically occurs concurrently with the fulminant clinical syndrome of hypertensive encephalopathy We describe occipital lobe seizures, in the setting of only moderate elevations of blood pressure, as the major clinical manifestation of RPLS.

The popularity of baseball has resulted in an increase in medical attention directed toward participating players. This study focuses on injuries of the throwing arm in adolescents which occur during participation in organized youth baseball matches. History taking, physical examination and roentgenographic study of both elbows were made on 67 adolescent baseball players who visited the Department of Orthopaedic Surgery of Hanyang Vniversity Hospital from December, 1981 to January, 1982. The results obtained were as follows: 1. The average age was 12.4 years and average career playing baseball was 1 year 11 months. 2. There were 18(85.7%) overhand type pitchers. This was the most common pitching style. 3. 7(10.4%) complained of elbow pain. In all cases the pain was located on the medial aspect of the elbow. 4, On physical examination, hypertrophy of the forearm was seen in 19(28.4%), hypertrophy of the arm in 27(40.3%), limb length discrepancy in 28(41.8%), cubitus valgus deformity in 2(3.0%), and flexion contracture of the elbow in 6(9.0%) cases. 5. On roentgenographic study, cortico-trabecular hypertrophy of the humerus, and separation and fragmentation of the medial humeral epicondyle were the common findings. 6. The pain and flexion contracture of the elbow were more marked in pitchers. 7. To prevent these injuries of the elbow, the following recommandations were made by authors. Use a pitching machine in batting exercise. Restrict the number of innings pitched per game, Abolish curve ball throwing in this age group. Ensue an adequate warmup period before exercise or games. Inform parents and coaches of the possible harmful nature of excessive throwing.

Incorporation of bromodeoxyuridine(BrdU) and expression of osteocalcin and transglutaminase C(TGase C) during fracture healing and distraction osteogenesis were investigated in the rat with immunohistochemical studies. Transverse osteotomy was made at the proximal tibia. Bilateral dynamic mini-fixator was applied to immobilize the fracture and also to lengthen the leg. Distraction was started, at the rate of 0.25 mm twice daily, from the 4th operative day and continued for 7 days. Animals were killed for immunohistochemical studies on the 1st, 3rd, 5th, 7th, 14th, 28th, 42nd, 56th, and 84th day after osteotomy or distraction. Longitudinal histologic sections of the healing bone were stained with monoclonal antibodies against BrdU, osteocalcin, and TGase C. Radiologically, complete fracture healing was achieved in 6 weeks after osteotomy, while neo-osteogenesis was successfully achieved in the distracted gap in 7 weeks after the completion of distraction, During active healing stage of the fracture and distraction osteogenesis, BrdU was mainly expressed in the perisoteal and endosteal osteoprogenitor cells while osteocalcin was expressed in the proliferating osteoprogenitor cells, osteoblast, osteocyte, osteoid matrix, and chondrocyte. The expression of BrdU and osteocalcin in the mesenchymal cells from the surrounding soft tissues around the osteotomy site was negligible. At the site of enchondral bone formation, TGase C was expressed in the cytomplasm of more centrally located and matured chondrocytes, while oseocalcin was mainly expressed in the cytoplasm of peripherally located chondrocyte. These findings may suggest that osteocalcin participates in early phase of enchondral bone formation, while TGase C in the late phase, suggesting the role of TGase C in matrix stabilization. At the site of intramern-branous bone formation, the expression of TGase C was weakly positive in both osteoprogenitor cell and osteoblast. The reason of the difference in the expression of TGase C between the enchondral bone formation and intrarnembranous bone formation should be further investigated. Fracture healing and distraction osteogenesis was predominantly induced by intramembranous ossification rather than enchondral ossification. Periosteal osteoprogenitor cells appeared to initiate and to lead bone formation after osteotomy and distraction. Active proliferation and differentiation of osteoprogenitor cell ocurred during entire periods of distraction. Also, active osteoid matrix formation and mineralization was started from the 5th day of distraction and continued thereafter for further 4 weeks after completion of the lengthening. These findings indicate that preservation of the periosteum is essential to achieve successful fracture healing and distraction osteogenesis.

Ultrasonographic and radiographic findings in 72 cases of pelvic masses which have been provedhistopathologically were analyzed. The results were as follows; 1. Among 72 cases, 28 cases were uterine massesand 44 cases were adnexal masses. 2. Pathologic accuracies of ultrasonographic diagnosis were 64.3% in uterinemasses, 70.5% in adnexal masses, and 68.1% in all pelvic masses. 3. Plain or IVP findings were not specific indiagnosis and showed secondary mass effects or functional disturbances. 4. Because of its high accuracy ofpathologic diagnosis and safety, ultrasonography can be regared as the most valuable and preferential study. Butin cases of cystic myomas, endometrioses, cystic missed abortions and huge masses, the accurate diagnoses weredifficult.

The purpose of this study was to investigate kinetics of the osteblast cell lineage in the periosteum and endosteum according to different distraction rates in callotasis of rats' Tibiae. 120 rats underwent osteotomy at the proximal metaphysio-diaphyseal junction of the left tibia for callotasis. Lengthening was started with varying distraction rates of 0.25 mm (group I), 0.5 mm (group II), 0.75 mm (group III), 1.0 mm (group IV) until 3.5 mm length gain was achieved. The animals that had osteotomy alone without lengthening served as a control(group V). Immunohistochemical staining of proliferating cell nuclear antigen(PCNA), osteocalcin and transglutaminase C(TGase C) were done on the four animals on each group sacrified at post-distraction 1, 3, 5, 7, 14, 28 days in order to observe the temporal changes among the experimental and control groups. At each examination, radiographic and histological studies were also done in order to correlate the immunohistochemical findings. The results obtained are summarized as follow; 1. The staining rate of PCNA was highest at the early distraction(day 1) phase and subsequently decreased in all groups. The staining rate of the cells in the periosteum was significantly higher than that of the cells in the endosteum (p < 0.01). 2. The expression rates of osteocalcin in the periosteum of all groups were significantly higer than those in the endosteum (p < 0.01). 3. The expression rates of TGase C in the periosteum of all groups were significantly higer than those in the endosteum (p < 0.05). 4. Radiological and histological studies revealed that successful regenerate bone healing was achieved in groups, I, II and III but not complete in group IV. In conclusion, immunohistochemical study on callotasis of rats' tibiae revealed that the osteoblast cell lineage in the periosteum is more activated than that in the endosteum for proliferation and differentiation by distraction, suggesting that the periosteum plays a more important role in neo-osteo-genesis in the distraction gap. Daily distraction rate range of 0.25 mm to 0.75 mm in two increments is the appropriate for successful distraction osteogenisis of rat's tibia, but the rate of 0.25 mm a day is significantly better than that of 0.75 mm upon immunohistochemical observation.
