Angiolymphoid hyperplasia with eosinophilia(ALHE) is a benign angiomatous neoplasm which usually arises from skin, blood vessel, soft tissue, heart and rarely from bone. The authors experienced a case of ALHE which involved the distal femur of 35-years old male and treated by marginal excision and autogenous cancellous bone graft with plate fixation.

There are several considerations in performing free vascularized fibular graft for the treatment of the large bone defect, e.g., bone fixation, additional bone graft, and management of complication. Authors have analyzed 25 cases treated with free vascularized fibular graft at Holy Family Hospital between Jun. 1985 and Dec. 1994. The mean follow up was 27.4 months The results were as follows: 1. The causes of the defect were traumatic defect with infection of 16 cases, bone tumor of 4 cases, congenital pseudoarthrosis of tibia of 3 cases and osteomyelitis of 2 cases. 2. Hypertrophy of the graft was more common in the lower extremity and in the patient under the age of 15. 3. Nonunion of graft occurred in 4 cases(16%). These cases were fixed with screws and/or pin ini tially and subsequently treated with rigid internal fixation. 4. Stress fracture of graft occurred in 3 cases(12%). Two cases of them were treated with internal fixation. 5. Additional bone graft were performed in 6 cases(24%), among 17 cases who had bone defect of lower extremity in adult. In conclusion, authors emphasize that rigid internal fixation and additional bone graft in performing free vascularized fibular graft are recommended for obtaining early solid bony union and achieving early rehabilitation.

Incidence of non-contiguous multiple spine fracture was increased from 3.2%~4.5% at 1960th and 70th to 5.7% ~23.8% at 80th and 90th. But there is no reports in Korea which has high incidence of traffic and industrial accidents. In 345 consecutive patients with acute spine fracture, we found that 43 patients (12.5%) had multiple non-contiguous spine fractures. At the 43 patients studies 37 (87.4%) sustained fractures at 2 levels while 6 had more than 3 levels of injury, 26 were injured by fall from heights, 27 (62.8%) had 2.33 associated injuries on an average, and 12 (27.9%) had a neurologic deficit. There are five patterns account for 26 (50%) of the total number of patients. In 19 patients (44.2%), there was a mean 29.3 days delay (from 3 to 233 days) in diagnosis of the minor lesions. In 19 delay diagnosed minor lesions, it confirmed by bone scan in 12 patinets(63.6%). Two patients died within 24 hours after accident, and 41 patients (41 major and 50 minor fractures) were treated in our hospital. Among them, 21 (51.2%) needed modification of treatment by the presence of non-con- tiguous multiple spine fractures. According to above findings, the physician must be aware of the possible noncontiguous multiple spine fractures when examine and treat the patients with spine fracture.

MicroRNA polymorphisms may be associated with carcinogenesis or immunopathogenesis of infection. We evaluated whether the mircoRNA-604 (miR-604) polymorphism can affect the persistence of hepatitis B virus (HBV) infection, and the development to hepatocellular carcinoma (HCC) in patients with chronic HBV infection. A total of 1,439 subjects, who have either past or present HBV infection, were enrolled and divided into four groups (spontaneous recovery, chronic HBV carrier without cirrhosis, liver cirrhosis and HCC). We genotyped the precursor miR-604 genome region polymorphism. The CC genotype of miR-604 rs2368392 was most frequently observed and T allele frequency was 0.326 in all study subjects. The HBV persistence after infection was higher in those subjects with miR-604 T allele (P=0.05 in a co-dominant and dominant model), which implied that the patients with miR-604 T allele may have a higher risk for HBV chronicity. In contrast, there was a higher rate of the miR-604 T allele in the chronic carrier without HCC patients, compared to those of the HCC patients (P=0.03 in a co-dominant model, P=0.02 in a recessive model). The T allele at miR-604 rs2368392 may be a risk allele for the chronicity of HBV infection, but may be a protective allele for the progression to HCC in chronic HBV carriers.

The purpose of this study was to evaluate the effects of a sealant resin on enamel demineralization in orthodontic bracket bonding. The forty eight extracted sound bovine teeth were subdivided into four groups and treated with Phase II(R) (Reliance, Itasca, Ill) on the surface. Group 1 was not treated. Group 2 was acid etched with 37% phosphoric acid for 30 seconds. Group 3 was applied with sealant after acid etching. Group 4 was applied with resin paste after acid etching and sealant application. Each group was demineralized in artificial caries solution. Demineralized enamel depth was measured by confocal laser scanning microscopy. The results were as follows: the mean demineralized enamel depth was 47.4 micrometer (Group 1), 61.8 micrometer (Group 2), 13.9 micrometer (Group 3), 8.2 micrometer (Group 4); the demineralized enamel depth was increased in Group 2 than in Group 1 (p < 0.05); the demineralized enamel depth was reduced in Group 3 than in Group1 and Group 2 with statistically significant differences (p < 0.05); and demineralization in Group 4 was very little. The results of the present study indicate that sealant application is useful for reducing enamel demineralization in orthodontic bracket bonding.

Paragangliomas of the orbit are extremely rare. A case of 43-year-old woman who presented with left exophthalmus of 1 month duration is described. The patient underwent surgery with gross total removal of the tumor and relief of her initial chief complaint of exophthalmus. We review the literature and discuss the clinical features and the pathogenesis of orbital paraganglioma.

Bilateral simultaneous Bell's palsy is extremely rare and occurs in about 0.3-2.0% of the facial palsy cases. In contrast to the unilateral form of facial palsy, which often has an unknown cause, bilateral facial palsy is increasingly recognized as secondary to a variety of other disorders, including neurological, infectious, traumatic, metabolic, vascular, neoplastic, and degenerative disorders. Yet, bilateral simultaneous Bell's palsy is by definition, not associated with any demonstrable disease along the course of the facial nerve or elsewhere in the body. So, as usual, it is important to make an early diagnosis for the best treatment. We report our experience with two cases of bilateral simultaneous Bell's palsy recently seen in our practice.

PURPOSE: Bronchopulmonary dysplasia (BPD) is characterized by arrested vascular and alveolar growth in the premature lung. Considering the consequences of arrested lung growth, the idea of administering bone marrow cells to enhance the inborn repair mechanism is promising as this may reduce the morbidity and mortality of BPD. We followed enhanced green fluorescent protein (EGFP)-labeled bone marrow cells (BMC) injected intraperitoneally into non-EGFP mice in order to determine their fate after transplantation. METHODS: An angiogenesis inhibitor, SU1498, was injected subcutaneously on day 3 in non-EGFP C57BL/6 newborn mice to create a model of arrested alveolar development. On the following day, 1x10(6) BMCs isolated from major histocompatibility complex (MHC)- matched syngenic EGFP mice were injected intraperitoneally to non-EGFP BPD mice. Morphometric analysis, immunostaining, and confocal microscopy were performed to determine the fate of EGFP-positive stem cells in the injured lung. RESULTS: SU1498 injection reduced alveolar surface area and mean alveolar volume in newborn mice. BMC injection resulted in recovery of lung structure comparable to controls. EGFP-positive BMCs were identified in the lungs of the recipient mice after intraperitoneal injection. The injected EGFP cells were co-stained with endothelial and epithelial cells of the developing lung as determined by confocal microscopy. CONCLUSION: Our results illustrated that EGFP-positive BMCs engrafted and trans- differentiated into epithelial and endothelial cells after intraperitoneal injection in a mouse model of arrested alveolar development.
