It has been emphasized that the treatment of choice for the trochantric fracture of the femur is open reduction and rigid internal fixation to reduce complications by early ambulation. The incidence of trochanteric fracture of the femur in the young age group has been considerably increased in recent years because of increased traffic and industrial accidents. The author treated 38 cases of trochanteric fracture of the femur in the year 1974 through 1979, at the Department of Orthopaedic Surgery, School of Medicine, Soon Chun Hyang College. The results were as follows: 1. In sex distribution, 24 out of 38 were males and 14 were females. 16 cases out of 24 male patients were in the age group 20-40 and 9 cases out of 14 female were over 60 years of age. Over all mortality was 7.9%. 2. The numbers of patients of type I and III were 11 cases in each type out of 38 trochanteric fracture. 3. 26 cases out of 38 cases were treated by open reduction and internal fixation and the others were by traction and cast. 4. The applied metal devices were 3 types: Smith-Peterson nail and Thornton or McLaughlin plate, compression hip screw, and multiple pinning. 5. Mean duration of bony union is shorter in the group of open reduction and internal fixation (13 weeks) than the group of traction and cast (15 weeks). The cause of difference is that the 6 out of 9 cases of type IV and V were included in conservative group. 6. The incidece of the complications such as coxa vara, slipping screw, long nail and traction palsy occurred higher in the group fixed with Smith-Peterson nail and plate than the group fixed with compression hip screw.

It is aging fast in Korea like other Asian countries. Social care systems, human resources, and appropriate senior products for elderly people are important factors to keep the society ealthy and productive. In this paper, we introduce the current status of senior products and standards in Korea including the Korea Senior Product Association (KSPA); present general status of the senior industry in Korea,long-term care insurance program for the elderly as well as welfare items; discuss problems and importance of standardization in the senior industry, the scope of senior products, and the current status of standardization.

Xanthogranulomatous cholecystitis (XGC) is an uncommon, focal or diffuse destructive inflammatory process of the gallbladder that is assumed to be a variant of chronic cholecystitis. XGC is characterized grossly by irregular thickening of the gallbladder wall with the formation of a yellow mass (xanthogranuloma). Histologically the xanthogranuloma appears as yellow nodules or streaks in a thickened gallbladder wall and is composed of predominantly lipid-laden macrophages, inflammatory cells, and fibroblasts. These xanthogranulomatous foci may extend into adjacent structures, adhesions or ulcerations are often present, and fistula formation may occur. Although the pathogenesis of XGC is unclear, recurrent inflammation in the presence of calculi and biliary stasis are thought to be the main etiological factors because of the histologic evidence of chronic inflammation and the presence of gallstones in a majority of cases. XGC may lead to associated complications such as perforation, abscess, and fistula, and sometimes closely mimics a gallbladder carcinoma. During an operation for XGC, careful surgical technique is required to dissect the gallbladder and to excise the adjacent xanthogranulomatous tissue. Also a careful investigation to find the coincident gallbladder carcinoma is necessary. We report a case with XGC in a hemophilia A patient and a review of the clinical literatures.

Percutaneous transhepatic biliary drainage (PTBD) is the basis for most biliary interventional pro cedures, and the application of preoperative PTBD to patients who have malignant obstructive jaundice has a significant effect on overall morbidity, mortality, and patient survival by allowing selective application of the most appropriate therapeutic modality. There are few case reports on subcutaneous metastasis of bile-duct cancer. We recently observed a subcutaneous metastasis at the catheter insertion site after PTBD in two patients with bile-duct cancer. Although tumor-cell seeding along the catheter tract is a very rare complication, we think that PTBD requires more attention when a curative resection is planned.

Background: Lipopolysaccharide (LPS) exerts cytotoxic effects on brain cells, especially on those belonging to the oligodendrocyte lineage, in preterm infants. The susceptibility of oligodendrocyte lineage cells to LPS-induced inflammation is dependent on the developmental stage. This study aimed to investigate the effect of LPS on oligodendrocyte lineage cells at different developmental stages in a microglial cell and oligodendrocyte coculture model. Methods: The primary cultures of oligodendrocytes and microglia cells were prepared from the forebrains of 2-day-old Sprague–Dawley rats. The oligodendrocyte progenitor cells (OPCs) co-cultured with microglial cells were treated with 0 (control), 0.01, 0.1, and 1 µg/mL LPS at the D3 stage to determine the dose of LPS that impairs oligodendrocyte differentiation. The co-culture was treated with 0.01 µg/mL LPS, which was the lowest dose that did not impair oligodendrocyte differentiation, at the developmental stages D1 (early LPS group), D3 (late LPS group), or D1 and D3 (double LPS group). On day 7 of differentiation, oligodendrocytes were subjected to neural glial antigen 2 (NG2) and myelin basic protein (MBP) immunostaining to examine the number of OPCs and mature oligodendrocytes, respectively. Results: LPS dose-dependently decreased the proportion of mature oligodendrocytes (MBP+ cells) relative to the total number of cells. The number of MBP+ cells in the early LPS group was significantly lower than that in the late LPS group. Compared with those in the control group, the MBP+ cell numbers were significantly lower and the NG2+ cell numbers were significantly higher in the double LPS group, which exhibited impaired oligodendrocyte lineage cell development, on day 7 of differentiation. Conclusion Repetitive LPS stimulation during development significantly inhibited brain cell development by impairing oligodendrocyte differentiation. In contrast, brain cell development was not affected in the late LPS group. These findings suggest that inflammation at the early developmental stage of oligodendrocytes increases the susceptibility of the preterm brain to inflammation-induced injury.

OBJECTIVE: To determine the possibility of a new measurement tool using electromyography and ultrasonography for quantitative spasticity assessment in post-stroke patients. METHODS: Eight hemiplegic stroke patients with ankle plantarflexor spasticity confirmed by a Modified Ashworth Scale (MAS) were enrolled. Spasticity was evaluated using the MAS and Modified Tardieu Scale (MTS). Each subject underwent surface electromyography (sEMG) using the Brain Motor Control Assessment (BMCA) protocol and was compared with a healthy control group. Using ultrasonography, muscle architecture and elasticity index were measured from the medial gastrocnemius muscle (GCM) on the affected and unaffected sides. RESULTS: MAS and MTS revealed significant correlation with sEMG activity. The fascicle length and pennation angle were significantly decreased in the medial GCM on the hemiplegic side compared with the unaffected side. The elasticity index of the spastic medial GCM was significantly increased compared with the unaffected side. The MTS X and R2–R1 values were significantly correlated with the elasticity index in the hemiplegic GCM. The relationship between clinical evaluation tools and both BMCA and sonoelastography was linear, but not statistically significant in the multiple regression analysis. CONCLUSION: The BMCA protocol and ultrasonographic evaluation provide objective assessment of post-stroke spasticity. Further studies are necessary to conduct accurate assessment and treatment of spasticity.

Squamous cell carcinoma antigen (SCC-Ag) is a well-established tumor marker for monitoring recurrence of squamous cell carcinoma of the cervix. However, serum levels of SCC-Ag could be elevated by some benign conditions not to speak of squamous cell malignancies other than cervical carcinoma. Sinonasal inverted papilloma is one of benign tumor which may elevate serum SCC-Ag level. We experienced a case of cervical carcinoma patient whose serum level of SCC-Ag was not normalized in spite of combination chemotherapy until surgical removal of maxillary inverted papilloma detected by PET/CT.
