Journal of the Korean Hip Society 2006;18(4):182-188
Purpose: To evaluate the results of blade plate fixation and bone grafting for the treatment of failed intertrochanteric hip fractures. Materials and Methods: Eight patients were treated with 95° blade plate fixation and bone grafts were performed in 7 patients. The mean age of the patients was 73 years old and the mean follow-up period was 26 months (range, 6 to 65 months). Clinical and radiological results were evaluated based on pain, walking ability, union period, and maintenance of reduction. Results: 6 of 8 patients obtained a solid union after a median period of 20 weeks. The neck-shaft angle was changed from 118° to 133° postoperatively. One patient underwent revision of a bipolar hemiarthroplasty due to failed blade plate fixation and varus malunion occurred in one patient Conclusion: Blade plate fixation and bone grafting for failed internal fixation of intertrochanteric hip fractures can provide a solid union and a good clinical result.

Apoptosis is an intrinsic and fundamental biological process that plays a critical role in the normal development of multicellular organisms and in maintaining tissue homeostasis. Some of the well known regulators of apoptosis are cytokines of the tumor necrosis factor(TNF) ligand family, such as Fas ligand(Fas L) and TNF, which induce apoptosis by activation of their corresponding receptors, Fas and TNFR-1. Recently, a new member of the TNF family known as TRAIL (TNF-related apoptosis-inducing ligand) was identified and shown to induce p53-independent apoptosis in a variety of tumor cell lines but not in normal cells, Four human receptors for TRAIL were also recently identified and designated TRAIL-R1, -R2, -R3, and -R4. The aim of this study is to examine whether TRAIL and TRAIL receptots(-R1, -R2, -R3) are expressed in uterine cervical cancer and whether it is correlated with apoptosis, TRAIL and TRAIL receptors. The subjects were 20 patients who were diagnosed with cervical cancer. Western blotting was performed in 9 cases, immunohistochemical staining for TRAIL and TRAIL receptors(-R1, -R2, -R3) and TUNEL method for detection of apoptosis in 11 cases. There were proteins for TRAIL, TRAIL-R1, -R2, and -R3 in tissues from cervical cancer. All TRAIL receptors were expressed in both normal cervical epithelium and tumor cells, and TRAIL-Rl and -R2 were more strongly expressed in tumor cells than normal epithelium(p<0.05). Apoptosis correlated with expression of TRAIL-Rl and -R2(p<0.05). This study suggests that TRAIL induces apoptosis in cervical cancer through its receptors.

BACKGROUND: Nonimmune hydrops fetalis has become an important perinatal problem since it was first described in 1943. Although recent advances in antenatal ultrasound have made it possible to detect and manage nonimmune hydrops fetalis in early pregnancy, the perinatal mortality is still high. OBJECTIVE: To obtain clinically useful data regarding antenatal diagnosis, management, and perinatal outcomes of nonimmune hydrops fetalis, and to assist clinicians offer proper antepartum counseling and obstetric management which may be able to improve prognosis. Study design: We retrospectively reviewed 33 cases of nonimmune hydrops fetalis delivered in our hospital over a 4-year period. RESULTS: The antenatal diagnosis was possible by ultrasonography in all cases. Accumulation of fluid in fetal serous cavity and generalized skin edema were observed in all cases. A probable etiology was found in 23 (69.7%) cases through ultrasonography, various laboratory studies including fetal karyotyping, and autopsies. These were cardiovascular (4), respiratory (6), chromosomal (4), skeletal (1), and others (8). Despite extensive diagnostic studies, no definite etiology was found in 10 (30.3%) cases. Excluding the ten fetuses delivered after induced abortion, eight infants were born alive and six died in the neonatal period. The mortality rate was 91.3% (21/23). CONCLUSION: Nonimmune hydrops fetalis represents a very poor perinatal outcome. It is suggested that to improve the prognosis, various antenatal and postnatal approaches to find associated etiologic factors should be performed, and intensive perinatal cares are needed.

BACKGROUND: Urinary tract infections (UTIs) are the most frequent nosocomial infections and are frequently associated with indwelling urinary catheters. It is known that adherence to standard infection control measures for urinary catheters can reduce UTIs in hospitals. This study was performed to evaluate the effect of education in reducing catheter-related UTIs (CR-UTIs) in intensive care units (ICUs) of a university hospital. METHODS: CR-UTIs were prospectively monitored for all patients with indwelling urinary catheters in ICUs from July 2006 through December 2007. Recommendations based on previously known guidelines for catheter insertion, catheter management, and specimen collection to prevent CR-UTIs were formulated and educated in March 2007. Knowledge and adherence level were evaluated before and after educating healthcare workers about the recommendations using questionnaire. Changes in knowledge and adherence level before and after education were compared by Chi-square test. Changes in the rate of CR-UTIs and urinary catheter utilization ratios were also analyzed by Fisher's exact test. RESULTS: After education, knowledge level of and adherence level to most of the recommendations were improved significantly. The rate of CR-UTIs significantly decreased by 48% from 7.43/1,000 catheter-days before intervention to 3.87/1,000 catheter-days after intervention (P=0.02). CONCLUSION: Surveillance for nosocomial infections and education for standard infection control measures are very important in preventing CR-UTIs in ICUs.

Colorectal cancer during pregnancy is rare but the trend for women to delay pregnancy until later in life may result in increased incidence of colorectal cancer during pregnancy. The most common symptoms are rectal bleeding, abdominal discomfort, abdominal distension, anorexia, nausea, vomiting, constipation, anemia and weight loss. Rectal bleeding, if it is occurred, is often attributed to hemorrhoids, a common finding of pregnancy and many of these symptoms are commonplace in normal pregnancy. This delays diagnosis of colorectal cancer during pregnancy and leads to more advanced stage and poor prognosis compared to the general population. We experienced a woman at 27 weeks gestation who complained of low abdominal distention and was diagnosed of sigmoid colon cancer and underwent cesarean section and hemicolectomy at 30 weeks gestation, so we present it with brief review of literature."

Microsatellites are short nucleotide repeat sequences present throughout the human genome. Alterations of microsatellites, comprising extra or missing copies of these se quences, have been termed microsatellite instability(MSI, genetic instability, replication errors, RER(+) phenotype). To date, at least four genes involved in DNA mismatch repair, hMSH2, hMLH1, hPMS1 and hPMS2, are thought to account for the observation of microsatellite instability in tumor from Hereditary nonpolyposis colorectal cancer (HNPCC) patients. The genetic defect responsible for the MIN+ phenotype in sporadic colorectal cancer, however, has yet to be clearly delineated. The purpose of this study was to determine the presence of MSI in sporadic cancer and to correlate its occurrence with clinicopathological parameters, we have studied six microsatellite loci by use of polymerase chain reaction amplification and denaturing polyacrylamide gel electrophoresis. We found that 20%(9 of 46 cases) sporadic colorectal cancers showed RER at two or several loci(RER+). Microsatellite instability was associated with location of the tumor in the proximal colon 66%(6 of 9 cases) and with poorly differentiated tumor phenotype 56%(5 of 9 cases). In order to better understand the role of somatic alterations within hMSH2 in the process of colorectal tumorigenesis, we examined the most conserved regions(codon 598~789) of this gene in nine patients with MIN spotadic colorectal cancer. 6 patient of RER(+) colorectal ca. patients had a polymorphism which was a T to C base change in the intron sequence at -6 position of the splice acceptor site at the 5'end of exon 13. This particular sequence variation is a polymorphism rather than a mutation which increase cancer susceptability. These data suggest that the genetic instability is detect ed in some colorectal cancers and play an important role in the pathogenesis of sporadic colorectal cancer.
