Purpose: This study reviewed screening and assessment tools that are used to measure delirium in patients with cancer in hospice and palliative care settings and examined their psychometric properties. Methods: Four databases were searched for studies using related search terms (delirium, tools, palliative care, cancer, and others). The inclusion criteria were a) studies that included screening/assessment tools for measuring delirium in cancer patients receiving hospice/palliative care, and b) studies published in English or Korean. The exclusion criteria were a) studies that were conducted in an intensive care setting, and b) case studies, qualitative studies, systematic reviews, or meta-analyses. Results: Out of the 81 studies identified, only 10 examined the psychometric properties of tools for measuring delirium, and 8 tools were ultimately identified. The psychometric properties of the Memorial Delirium Assessment Scale (MDAS) were the most frequently examined (n=5), and the MDAS showed good reliability, concurrent validity, and diagnostic accuracy. The Delirium Rating Scale had good reliability and diagnostic accuracy. The Delirium Rating Scale-Revised 98 also showed good reliability and structural validity, but its diagnostic performance was not examined in hospice/palliative care settings. The Nursing Delirium Screening Scale showed relatively low diagnostic accuracy. Conclusion The MDAS showed evidence of being a valid assessment tool for assessing delirium in patients with cancer in palliative care. Few studies examined the diagnostic performance of delirium tools. Therefore, further studies are needed to examine the diagnostic performance of screening/assessment tools for the optimal detection of delirium in patients with cancer in hospice/palliative care.

Recently, next generation sequencing (NGS) has received attention as the ultimate genotyping method to overcome the limitations of capillary electrophoresis (CE)-based short tandem repeat (STR) analysis, such as the limited number of STR loci that can be measured simultaneously using fluorescent-labeled primers and the maximum size of STR amplicons. In this study, we analyzed 15 autosomal STR markers via the NGS method and evaluated their effectiveness in STR analysis. Using male and female standard DNA as single-sources and their 1:1 mixture, we sequentially generated sample amplicons by the multiplex polymerase chain reaction (PCR) method, constructed DNA libraries by ligation of adapters with a multiplex identifier (MID), and sequenced DNA using the Roche GS Junior Platform. Sequencing data for each sample were analyzed via alignment with pre-built reference sequences. Most STR alleles could be determined by applying a coverage threshold of 20% for the two single-sources and 10% for the 1:1 mixture. The structure of the STR in each allele was accurately determined by examining the sequences of the target STR region. The mixture ratio of the mixed sample was estimated by analyzing the coverage ratios between assigned alleles at each locus and the reference/variant ratios from the observed sequence variations. In conclusion, the experimental method used in this study allowed the successful generation of NGS data. In addition, the NGS data analysis protocol enables accurate STR allele call and repeat structure determination at each locus. Therefore, this approach using the NGS system will be helpful to interpret and analysis the STR profiles from singe-source and even mixed samples in forensic investigation.

Polyethylene wear is one of the major problems following total knee arthroplasty. Many factors affect the degree and the pattern of polyethylene wear. We experienced three cases of early catastrophic poly- ethylene wears. All cases showed flexion contracture with severe genu varum deformity and total knee arthroplasty was performed with Advantim total knee prostheses in all cases. Postoperatively, bony align- ment and ligament balancing were good in all cases. However, in 12 to 22 months later, lateral subluxa- tion and valgus instability were developed with early catastrophic polyethylene wear especially in the medial compartments. Flat surface geornetry of polyethylene might be responsible for the development of lateral subluxation and early catastrophic wears. From these experience, we concluded that the mediolat- eral as well as anteroposterior dishing is essential for the stability of the artificial joint and prevention of early rapid wear of polyethylene articular inserts following total knee arthroplasty.

BACKGROUND: Heme oxygenase-1 (HO-1) is an inducible enzyme that catalyzes the oxidative degradation of heme to form biliverdin, carbon monoxide (CO), and free iron. The current evidence has indicated a critical role of HO-1 in cytoprotection and also in other, more diverse biological functions. It is known that the high expression of HO-1 occurs in various tumors, and that HO-1 has an important role in rapid tumor growth because of its antioxidative and antiapoptotic effects. Therefore, the role of HO-1 was analyzed in human lung cancer cell lines, and especially in the A549 cell line. MATERIAL AND METHODS: Human lung cancer cell lines, i.e., A549, NCI-H23, NCI-H157 and NCI-H460, were used for this study. The expression of HO-1 in the untreated state was defined by Western blotting. ZnPP, which is the specific HO inhibitor we used, and the viability of cells were tested for by conducting MTT assaysy. The HO enzymatic activity, as determined via the bilirubin level, was also indirectly measured. Moreover, the generation of intracellular hydrogen peroxide (H2O2) was monitored fluorimetrically with using a scopoletin-horse radish peroxidase (HRP) assay and 2',7'-dichlorofluorescein diacetate (DCFH-DA). We have also transfected small HO-1 interfering RNA (siRNA) into A549 cells, and the apoptotic effects were evaluated by flow cytometric analysis and Western blotting. RESULTS: The A549 cells had a greater expression of HO-1 than the other cell lines, whereas ZnPP significantly decreased the viability of the A549 cells more than the viability of the other lung cancer cells in a dose-dependant fashion. Consistent with the viability, the HO enzymatic activity also was decreased. Moreover, intracellular H2O2 generation via ZnPP was induced in a dose-dependent manner. Apoptotic events were, then induced in the HO-1 siRNA transfected A549 cells. CONCLUSION: HO-1 provides new important insights into the possible molecular mechanism of the antitumor therapy in lung cancer.

A 43-year-old female presented with persistent headache and dizziness which had first occurred two years earlier. The physical and neurological findings at admission were unremarkable, though plain radiography revealed the presence of a dense calcified mass in the left frontal area, and CT showed that a homogeneous high-density nodule was attached to the inner surface of the left frontal skull. The hard bony mass found and excised during surgery was shown at histopathologic examination to be a subdural osteoma. We describe the clinicopathologic findings of this entity and discuss the radiological features which suggest its subdural location.

OBJECTIVE: To assess the effect of fentanyl and midazolam on in vitro fertilization rate and early embryo development in a mouse IVF model. METHODS: Mouse oocytes were exposed in vitro to fentanyl at a concentration of 0(control), 50, 250, 500, 1000, 5000 pg/ml, and midazolam, 0(control), 2.5, 12.5, 25, 50, 250 ng/ml for 30 minutes, washed and inseminated. Thereafter fertilization was assessed. And subsequent in vitro development to the blastocyst stage was monitored daily. RESULTS: Where fertilization occurred, subsequent embryo cleavage and development up to the blastocyst stage was affected significantly by the presence of fentanyl and midazolam solution in the medium(i.e., 14% to 31%, 10% to 35%), in comparison with control group( 60%, 62%). CONCLUSION: It can be concluded from these experiments that even a brief exposure of cumulus enclosed oocytes to a low concentration of fentanyl, midazolam is deleterious to subsequent cleavage.

BACKGROUND: To study the prognosis of patients with lung cancer, many investigators have reported the methods to detect cell proliferation in tissues including PCNA, thymidine autoradiography, flow cytometry and Ki-67. PCNA, also known as cyclin, is a cell related nuclear protein with 36KD intranuclear polypeptide that is maximally elevated in S phase of proliferating cells. In this study, PCNA was identified by paraffin-embedding tissue using immunohistochemistry which has an advantage of simplicity and maintenance of tissue architecture. The variation of PCNA expression is known to be related with proliferating fraction, histologic type, anatomic(TNM) stage, degree of cell differentiation, S-phase fraction and survival rate. We analyzed the correlation between PCNA expression and S-phase fraction, survival. METHODS: To investigate expression of PCNA in primary lung cancer, we used immunohistochemical stain to paraffin-embedded sections of 57 resected primary non-small cell lung cancer specimen and the results were analyzed according to the cell type, cell differentiation, TNM stage, S-phase fraction and survival. RESULTS: PCNA expression was dMded into five group according to degree of staging(-, +, ++, +++,++++). Squamous cell type showed high positivity than in adenocarcinoma. Nonsignificant difference related to TNM stage was noticed. Nonsignificant difference related to degree of cell differentiation was noticed. S-phase fraction was increased wit advance of PCNA positivity, but t could not reach the statistic significance. The 2 year survival rate and median survival time were -50% 13 months, +75% 41.3 months, ++73% 33.6 months, +++67% 29.0 months, ++++25% 9 months with statistic significance (P<0.05, Kaplan-Meier, generalized Wilcox). CONCLUSION: From this study. PCNA expression was high positive n squamous cell cancer. And, there was no relationship between PCNA positivity and TNM stage, cellular differentiation or S-phase fraction. But, the patients with high positive PCNA staining showed poor survival rate than the patients with lower positive PCNA. It was concluded that PCNA immunostaining is a simple and useful method for survival prediction in paraffin embedded tissue of non-small cell lung cancer.
