Although many reports have been published about Legg-Calve-Perthes disease, developmental dysplasia of hip, it is difficult to gain a satisfactory results in treatment. We experienced 9 year-old girl with ipsilateral neglected DDH combined with contralateral LCPD, and treated with Klisic operation for DDH and femoral valgus osteotomy for hinged abduction of LCPD. We gained satisfactory results and report this rare case.

Twenty five patients (twenty seven hips) who had Chiari osteotomy at Kang Nam St. Marys Hospital between 1980 and 1995 were reviewed to evaluate the factors in the operative technique that contribute to successful outcome and assess the clinical results in various conditions. The length of follow-up ranged from one to fourteen years and the age of at operation ranged from four to twentythree years. Eighteen patients had developmental dysplasia of the hip: four, septic hip: three had another disorders, Prior to the Chiari osteotomy, fourteen hips had an femoral osteotomy and four, trochanteric arthroplasty. We used to the standard osteotomy as described by Chiari with certain modification. A pneumatic saw and osteotome are used instead of Gigli saw. This technique is simple procedure to make the correct level and angle. Bone graft was not performed in all cases even the osteotomy was displaced more than 50 percent of the iliac width. The overall results were 12 excellent, eight good, five fair, and two poor. In eleven patients, the osteotomy had to be displaced more than 50 percent to provide good coverage of the femoral head. Their results were good or excellent. A good result will be obtained if enough attention is paid to displacing the osteotomy. The osteotomy using the pneumatic saw provides accurate level and direction of osteotomy and it is an simple procedure also.

Amphetamine, a synthetic psychostimulant, is transported by the dopamine transporter (DAT) to the cytosol and increases the exchange of extracellular amphetamine by intracellular dopamine. Recently, we reported that the phosphorylation levels of ezrin-radixin-moesin (ERM) proteins are regulated by psychostimulant drugs in the nucleus accumbens, a brain area important for drug addiction. However, the significance of ERM proteins phosphorylation in response to drugs of abuse has not been fully investigated. In this study, using PC12 cells as an in vitro cell model, we showed that amphetamine increases ERM proteins phosphorylation and protein kinase C (PKC) beta inhibitor, but not extracellular signal-regulated kinase (ERK) or phosphatidylinositol 3-kinases (PI3K) inhibitors, abolished this effect. Further, we observed that DAT inhibitor suppressed amphetamine-induced ERM proteins phosphorylation in PC12 cells. These results suggest that PKCbeta-induced DAT regulation may be involved in amphetmaine-induced ERM proteins phosphorylation.

Mucormycosis is an uncommon opportunistic fungal infection mostly affecting immunocompromised patients and gastrointestinal mucormycosis is a rare and life-threatening. We describe a 31-year-old man with a history of idiopathic cyclic neutropenia who developed perforations of the stomach and intestine and intra-abdominal bleeding due to disseminated gastrointestinal mucormycosis after the initial operation.

To facilitate the establishment of mixed chimerism with limited dose of bone marrow (BM) cells, and to achieve tolerance in skin graft model, combined blocking of costimulatory pathway and IL-2 pathway was used in minimally myeloablative model using busulfan. BM cells (2.5 x 10(7)) of BALB/c were injected into C57BL/6 mice at day 0 with full thickness skin graft after single dose injection of busulfan (25 mg/kg) on day-1. Recipients were grouped and injected the anti-CD154, CTLA4-Ig, anti-IL-2R at days 0, 2, 4, and 6 according to protocol. Mixed macrochimerism were induced in groups treated with anti-CD154+anti-CTLA4-Ig, anti-CD154+anti-IL-2R, and anti-CD154+anti-CTLA4 Ig+anti-IL-2R. Three groups having chimerism enjoyed prolonged graft survival more than 6 months. Superantigen deletion study revealed deletion of alloreactive T cells in combined blockade treated groups. In graft versus host disease model using CFSE staining, CD4+ T cell and CD8+ T cell proliferation were reduced in groups treated with CTLA4-Ig or anti-IL-2R or both in combination with anti-CD154. However, anti-IL-2R was not so strong as CTLA4-Ig in terms of inhibition of T cell proliferation. In conclusion, IL-2 pathway blocking combined with anti-CD154 can establish macrochimerism with limited dose of BM transplantation and induce specific tolerance to allograft.

Pericentric inversion is not rare in humans and is usually benign. However, pericentric inversion can lead to production of an unbalanced recombinant and might be a cause of repetitive pregnancy loss. Pericentric inversion of chromosome 22 is rare and only a few cases have been reported. We report a case of inv(22)(p13q12) carrier who had history of repetitive pregnancy loss including three spontaneous abortions and one fetal hydrops in which the chromosomal complement was rec(22)dup(22q) inv(22)(p13q12)mat. The maternal inv(22) and fetal rec(22) were confirmed by fluorescence in situ hybridization using region-specific probes (TUPLE1 on 22q11.2 and ARSA on 22q13). Because the identification of inv(22) or rec(22) in conventional karyotyping might be easily overlooked, great attention and additional molecular tests are required for accurate diagnosis of inv(22) and rec(22).
