A case of thumb-in-palm deformity due to burn scar contracture. Recently it is felt that the incidence of thumb-in-palm deformity due to old burn scar contracture is far less than that of other causes; for example carebral palsy, trauma, Co. poisning etc; This case is a 23 years old male soldier who had sustained burn on the left palm at his age of 4, and the left thumb has been gradually contracted, resulting to established thumb-in-palm deformity evantually. There is no active or passive motion in the metacarpho-phalangeal phalangeal joint and carpho-metacarpal joint of left thumb. The distal phalanx is moderately atrophied and its nail is deformed. On act 6th, 1975 he was operated on soft-tissue releasing with Z-plasty fasciotomy of palmar aponeurosis and myotomy of adductor pollicis and flexor pollicis brevis with split thickness skin graft. Postoperatively he could have full extension of the left thumb as well as active flexion of metacrpho-phalangeal and interphalangeal joint with slight adducted state. He is able to take opposition of left thumb at the present time postoperative four weeks.

It is often difficult to achieve bony union and eradicate infection in treating infected non-unions of the fractured long bones. Authors carried out a clinical analysis of the 35 infected non-union cases, all aged 21 years or older, treated and followed for 6 months to 6 years from July 1979 to July 1988 in order to determine the possible factors which might influence the time required for attaining union. The results were as follows: l. In 22 of the 35 infected non-unions, the primary fracture site was open (62.9%). The remaining 13 cases (37.1% ) were the closed fractures associated with postoperative infection. 2. The sites of infected non-union were tibia in 19 (54.3%), femur in 13 (37.1%), and upper extremity in 3 (8.6%) cases. Tibia was more often involved in open fractures (63.6%). Femur, on the other hand, was more involved in closed fractures (61.5%). 3. After an average of 3.3 times of bony procedures, primary fixation was left in place in 15 (42.9%), external fixation was required in 11 (31.4%), and internal fixation was performed in 9 (25.7%). Bone graft was performed in 26 cases (74.3%). 4. Time required for achieving union was 7.1 month with stable primary fixation and 21.7 months with unstable primary fixation. Femur and tibia united at 10.5 (mean; ranged from 4 to 29) and 7.0 (mean; ranged from 3 to 19) months, respectively. 5. Bony union was delayed as the number of prior surgical procedures before successful treatment increased; the time for union was significantly shorter when either stable primary fixation or external fixation was combined with bone grafting. 6. Firmer bony union was achieved after performing Osteoperiosteal decortication with autogenous cancellous bone graft even in the presence of remaining infection at the non-union site.

PURPOSE: This study focused on in vitro cell differentiation and surface characteristics in a magnesium coated titanium surface implanted on using a plasma ion source. MATERIALS AND METHODS: 40 commercially made pure titanium discs were prepared to produce Ti oxide machined surface (M) and Mg-incorporated Ti oxide machined surface (MM). Surface properties were analyzed using a scanning electron microscopy (SEM). On each surface, alkaline phosphatase (ALP) activity, alizarin red S staining for mineralization of MC3T3-E1 cells, and quantitative analysis of osteoblastic gene expression, were evaluated. Actin ring formation assay and gene expression analysis of TRAP and GAPDH performing RT-PCR were performed to characterize osteoclast differentiation on mouse bone marrow-derived macrophages (BMMs). RESULTS: MM showed similar surface morphology and surface roughness with M, but was slightly smoother after ion implantation at the micron scale. M was more hydrophobic than MM. No significant difference between surfaces on ALP activity at 7 and 14 days were observed. Real-time PCR analyses showed similar levels of mRNA expression of the osteoblast phenotype genes; osteopontin (OPN), osteocalcin (OCN), bone sialoprotein (BSP), and collagen 1 (Col 1) in cell grown on MM at 7, 14 and 21 days. Alizarin red S staining at 21 days showed no significant difference. BMMs differentiation increased in M and MM. Actin ring formation assay and gene expression analysis of TRAP showed osteoclast differentiation to be more active on MM. CONCLUSION: Both M and MM have a good effect on osteoblastic cell differentiation, but MM may speed the bone remodeling process by activating on osteoclast differentiation.

Various hantaviruses were isolated from HFRS patients and various rodent species, in many parts of the world. Bandicotas were captured at Yogyakarta, east region of Sumatura island, Indonesia; and 4 rodents species including Bandicotas were captured at Chiang Rai in Thailand during 1995. Sera were collected from captured andicotas and other rodent spicies were screened for antibody test against Hantaan (HTN), Seoul (SEO), Puumala (PUU) and Sin Hombre (SN) viruses by immunofluoresence antibody assay (IFA). Hantavirus antigen in lung tissues were tested by IFA. Among 55 captured Bandicota indica in Indonesia, 14 (25.5%) were antibody positive against HTN, SEO, PUU and SN virus. Hantavirus antigen were detected from 5 (9.0%) out of 55 lungs tested. Among 34 captured Bandicota indica in Thailand, 9 (26.5%) were antibody positive against HTN, SEO, PUU and SN virus. Among 34 lungs tissues of Bandicota indica examined, 3 (8.8%) were antigen positive. In other rodent species, antibody positive against Hantaviruses of Rattus rattus, Rattus losea and Mus cervicolor were 4/62(6.5%), 5/25(20%), 1/1(100%), respectively. But no one has antigen in their lung tissues. Antigen positive lungs suspension were inoculated into vero E6 cells for virus isolation and 4 viruses were isolated from Indonesian Badicota and 3 viruses from Thailand.

Massive hemorrhage into an intracranial neurinoma is a rare event. A 42-year old man noticed hearing loss, nystagmus, diplopia and paresthesia on the left side of the face. A computerized tomography scan demonstrated a large high density mass in the left cerebellopontine angle. The tumor was successfully removed and postoperative course was favorable. Such a case of acoustic neurinoma which revealed itself through intratumoral hemorrhage has not been previously reported in Korea.
