The incidence of intertrochanteric fracture of femur in young adult is relatively high in our home than other countries. But recently the incidence in elderly patient is progressively increased due to prolongation of average life span and increased activity. Various devices has been developed and the result of treatment has been improved, but the morbidity after fracture in elderly patient remains high because of poor general condition and osteoporosis. We tried to assess the availability of SHCP(sliding hip compression plate) in the intertrochanteric fracture of the osteoporotic bone by the review of the 27 cases below Singh index III that we experienced from September, 1989 to June, 1993 at the Department of Orthopedic Surgery of Chonbuk National University Hospital. The results were as follows: 1. Mean age was 68 years. Type III in Tronzo classification was most common(51.9%). Singh index II was 17 cases(63%) and grade III was 10 cases(37%). 2. In 23 cases(88.8%), anatomical reduction was performed. The bony union was gained at average 15.8 weeks. The serious complications were 1 penetration and 1 osteoarthritis of hip. 3. Satisfactory results were obtained in 88% of patients by the functional class of Clawson DK.

This study was done to present a criterion in selection of the most proper light sources and materials by measuring metamerism index(MI) of the light curing composite resins with spectrocolorimeter. Metamerism is defined when two objects appear to be the same color in one illuminant but different in another. This is due to the fact that they have different spectral curves that fail to match under the second illuminant. In this study, A1 & A3 shade of five light curing composite resins (Esthet-X, Filteck Z250, Filteck A110, Charisma, Vitalescence) were chosen based on Vita shade. Five samples were made for shade of each product with Teflon mold (diameter: 15mm, thickness: 2mm). Metamerism index of each samples on a Barium sulfate plate (L*=96.54, a*=0.19, b*=0.01) prepared for sample fixation were measured with spectrocolorimeter(Miniscan XE plus, Model 4000s, Hunter Lab, USA) by applying standard light source D65, C, Fcw, TL84 and A. Standardization was done with reference standard (X=80.8, Y=85.7, Z=90.8) and light trap. The results were as follows. 1. Different resins with same Vita shade showed recognizable color difference(DeltaE*>2). 2. All composites had MI below accepted value 0.5 between standard illuminant(D65, C, & A) and below 1.5 under fluorescent condition (Fcw & TL84). 3. MI value between D65 and A showed higher value than MI value between other source of light(p<0.01). 4. All resins except Z250 showed MI value that A3 is higher than A1 between D65 and A(p<0.05).

We conducted this cohort analytic study to determine whether women with unexplained elevations of maternal serum hCG at 15-18 weeks' gestation are at increased risk for pregnancy complications and adverse perinatal outcomes. The inclusion criteria were a singleton gestation, a confirmed gestational age, and an hCG level greater than 2.0 multiples of the median (MoM). The exclusion criteria were fetal anomalies, an abnormal karyotype, molar pregnancy, and an MSAFP level greater than 2.5 multiples of the median (MoM). A group of randomly selected women with hCG levels under 2.0 MoM served as controls. Patients with elevated levels of hCG had a significantly higher risk for PIH (17.9% versus 4.5%; P <.05) and preterm delivery (17.9% versus 3.5%; P<, 05) than control. But no significant differences were observed in the incidence of intrauterine growth restriction and low birth weight and in the newborn weight. We suggested that pregnancies with unexplained elevated hCG levels should be regarded as high-risk pregnancies. And these patients require careful monitoring with adequate obstetric management.

This study was undertaken to investigate mineral changes in weathered scalp hair after burial. EDX (energy dispersive X-ray spectroscopy) analysis was performed to measure the presence of minerals on the hair surface. Twelve scalp hairs, buried for 5-40 years, were chosen from deceased individuals buried in tombs in Soha-Ri, Kyonggi-Do, and other regions in Korea. Three normal hairs were used as the control group. EDX data showed that carbon, oxygen, and sulfur were detected in hair collected from all three burial grounds. In contrast, calcium was only detected in hair collected from tombs in Soha-ri. The amounts of calcium and sulfur were found to decrease with time for hair collected from tombs in Soha-ri. Similar results were observed with sodium for hair collected from other regions. These results show region specific mineral detection and a decrease in the concentration of minerals with time. Consequently, it is suggested that changes in minerals concentration in weathered hair could be used as basic data in the field of forensic medicine.

Various cancer types have been associated with cancer-related cerebral infarction. In this study, we describe the first case of cancer-related cerebral infarction in which the underlying disease was primary bone marrow lymphoma (PBML). A 79-year-old man presented with abruptly developed bilateral lower extremity weakness and confusion. Diffusion-weighted imaging on admission showed multiple cortical and subcortical embolic infarction lesions in multiple vascular territories. Diagnostic evaluations to determine the embolic source revealed no abnormalities. Laboratory testing demonstrated elevated D-dimer (2.59 μg/mL) but no other prothrombotic abnormalities. In suspicion of cancer-related stroke, we performed chest CT, abdomen CT, and FDG-PET to detect the hidden malignancy. Findings revealed no evidence of cancer; however, they did reveal signs of anemia (hemoglobin 9.0 g/dL). Bone marrow aspiration biopsy showed large atypical B cell involvement suggestive of high-grade B cell lymphoma. The patient was diagnosed with primary bone marrow diffuse large B-cell lymphoma initially presenting with ischemic stroke. Our case suggests that primary bone marrow cancer may be a candidate for the differential diagnosis of hidden malignancy in patients with suspected cancer-related stroke. Bone marrow biopsy may be essential for establishing an appropriate differential diagnosis in patients with abnormal hematologic findings.

Purpose: This study investigated the incidence and risk factors of cataract in people with diabetes mellitus (DM) using data from Ansan cohort of the Korean Genome and Epidemiology Study (KoGES). Methods: Data from a total of 329 patients with type 2 DM without cataract who participated in Ansan cohort of the KoGES from baseline survey (2001–2002) to fifth follow-up visit (2011–2012) were examined.The characteristics of the subjects were analyzed with frequency and percentage, and mean and standard deviation. Cataract incidence was measured as incidence proportion (%). For risk factors of cataract, hazard ratio (HR) and 95% confidence interval (CI) were obtained using the Cox proportional hazard model. Results: The cataract incidence over a 10-year follow-up period was 19.1% (15.1 in males and 25.8 in females), and mean age at the incidence of cataract was 63.48 years (61.58 years in males and 65.31 years in females). Age (HR=1.09, 95% CI=1.05–1.13) and HbA1c (HR=1.21, 95% CI=1.07–1.37) or the duration of DM (HR=1.05, 95% CI=1.00–1.09) were found to be independently associated with cataract development. Conclusion Cataract development in people with DM is common, and its likelihood increases with age, HbA1c, and the duration of DM. Considering negative effect of cataract on their quality of life and economic burden, nurses should identify people with DM at a higher risk of cataract development, and plan individual eye examination programs to detect cataract development as early as possible.

This study was carried out in order to determine in vitro biocompatibility of white mineral trioxide aggregate (MTA), and to compare it with that of the commonly used materials, i. e. calcium hydroxide liner (Dycal), glass ionomer cement (GIC), and Portland cement which has a similar composition of MTA. To assess the biocompatibility of each material, cytotoxicity was examined using MG-63 cells. The degree of cytotoxicity was evaluated by scanning electron microscopy (SEM) and a colorimetric method, based on reduction of the tetrazolium salt 2,3 bis {2methoxy 4nitro 5[(sulfenylamino) carbonyl] 2H tetrazolium hydroxide} (XTT) assay. The results of SEM revealed the cells in contact with GIC, MTA, and Portland cement at 1 and 3 days were apparently healthy. In contrast, cells in the presence of Dycal appeared rounded and detached. In XTT assay, the cellular activities of the cells incubated with all the test materials except Dycal were similar, which corresponded with the SEM observation. The present study supports the view that MTA is a very biocompatible root perforation repair material. It also suggests that cellular response of Portland cement and GIC are very similar to that of MTA.

OBJECTIVE: To overcome the limitations of the single gene transfer, the authors present the results of wild-type p16 and p53 combined genes transfer in vitro to the U251MG and U373MG cell lines using cationic liposome as a vector. METHODS: To compare the therapeutic effect of the combined p16 and p53 genes transfer with the single p16 and p53 gene transfer, full length of wild-type human p16 and p53 gene, and combined p16-p53 genes were transferred in vitro to the U251MG and U373MG cell lines using cationic liposome as a vector. As the U251MG and U373MG cell lines are devoid of p16 and p53 genes, the therapeutic effect of the three groups of gene transfer could be evaluated by the growth suppression or percentage of the viable cells. Reverse transcription polymerase chain reaction(RT-PCR), flow cytometry, and electron microscopy(EM) were used for evaluation of the growth suppression or apoptosis of the tumor cells. RESULTS: p16 gene, p53 gene and the combined p16-p53 genes were effectively transferred to the cell lines using cationic liposome as a vector resulting in dramatic decrease of the viable tumor cells in comparison to the control group(p=0.004). The cytotoxic effect of the gene transfer in the U251MG cell line was the most significant in the combined p16-p53 group. However, in the U373MG cell line p53 single gene transfer group showed more significant effect than the combined gene transfer group. Apoptosis was confirmed by EM in the combined p16-p53 genes group. The G1 phase arrest effect, confirmed by the flow cytometry was more prevalent in the p16 gene transfer group than the other groups. CONCLUSION: Cationic liposome-mediated transfer of combined p16-p53 genes to the human glioblastoma cell lines is proven effective. However, the therapeutic effect of the combined p16-p53 genes transfer was not consistently superior to the single p16 or p53 gene transfer.
