OBJECTIVE: To establish the evaluation system of the quality of oocytes on the basis of the incidence of cumulus cells apoptosis, to investigate the relationships between the incidence of cumulus cells and the outcomes of IVF-ET. METHOD: Thirth-four cycles undergoing controlled ovarian hypersimulation for IVF-ET with tubal infertility (23 cycles) or unexplained infertility (11 cycles) were included in this study. Cumulus cell masses surrounding mature oocyte and co-culture of embryos with autologous cumulus cells during IVF-ET process. The incidence of apoptosis in cumulus cells was assessed by apoptosis detection kit fluorescein. The effect of co-culture using cumulus cells and the incidence of cumulus cells apoptosis. RESULTS: The results were as follows: 1. The incidence of apoptosis in cumulus cells markedly increased in patients aged 40 or over, while the fertilization rate was greatly decreased in those age group. 2. Apoptosis in cumulus cells was found in both the fertilized oocytes and unfertilized oocytes, but the incidence of apoptosis was higher in unfertilized oocytes. 3. There is no clear correlation between apoptosis in cumulus cells and the number of oocytes retrieved. However, the incidence of apoptosis was increased when the number of oocytes retrieved was 5 and fewer in comparison with 6~10. 4. Embryo grade was significantly affected by the incidence of apoptosis in cumulus cells. 5. Pregnancy rate of IVF-ET per cycle was 29.4%, and the pregnant group had the higher fertilization rate and a significantly lower incidence of apoptosis in cumulus cells compared with the nonpregnant group. 6. When cumulus cells were used as helper cells in the co-culture of the embryo, in vitro activity of cumulus cells based on morphological change and proliferation did not influence the quality of embryo, but was closely associated with the implantation rate and pregnancy rate, which was enhanced when morphological changes and proliferation of cumulus cells was more active. 7. This difference in the outcome of IVF-ET according to in vitro activity of cumulus cells used for co-cultue was not associated with the incidence of apoptosis in cumulus cells, but rather had likely relations with the different secretion pattern of protein, which may be an embryotrophic factor by cumulus cells. CONCLUSION: These results suggest that the incidence of apoptosis in cumulus cells can be used in predicting oocyte qualities and the outcomes of IVF-ET. And the effect of co-culture largely depends on the in vitro activity of cumulus cells as well.

5.Photodynamic Therapy Treatment for Eyes with Drusenoid Pigment Epithelium Detachment.
Korean Journal of Ophthalmology 2008;22(3):194-196
We report the clinical course of photodynamic therapy (PDT) in a patient with drusenoid pigment epithelium detachment (PED). A patient with drusenoid PED underwent PDT follow-up was carried out at one week, one month, three months, six months and one year after treatment. Fundus exam, optical coherence tomography (OCT) and fluorescein angiography were performed. After the PDT, drusen and PED were gradually diminished over one year. However, pure serous PED eventually developed at the same location of the drusenoid PED. The results of the PDT, on drusenoid PED, were initially effective, but not completely successful. Therefore, PDT may be considered as an alternative treatment option for drusenoid PED.

Purpose:
Discharge readiness for parents of high-risk infants is an important predictor of successful transitions from hospital to home, however its assessments criteria require further refining in Korea. The purpose of this study is to provide a comprehensive overview of the measures available for assessing the discharge readiness for parents of high-risk infant and to evaluate the measurement properties of each instrument.
Methods:
A literature search for discharge readiness for parents of high-risk infants was performed using 8 electronic databases (MEDLINE, Embase, CINAHL, PsycINFO, Web of Science, KoreaMED, RISS, KISS), using preferred reporting items as per the systematic reviews guidelines. For the quality evaluations of the articles, the COSMIN checklist including content validity, internal structure, and the remaining measurement properties was used.
Results:
Among the 23 studies selected, 8 studies were excluded due to lack of information on their instrument’s measurement properties while remaining 15 studies were evaluated for the quality of measurement attributes. Overall information on the properties of the instruments was lacking in all studies.
Conclusion
None of the instruments evaluated all the relevant measurement properties. The results of this review suggest that it is necessary to develop a discharge readiness instrument that considers the necessary and relevant characteristics required for successful hospital to home transition for parents of high-risk infants.

The study is designed as a systematic review on nonpharmacological interventions for patients with moderate to severe dementia. This review will be conducted in accordance with the Cochrane Handbook for Systematic Reviews of Interventions. The following databases will be searched: Cochrane CENTRAL, MEDLINE, EMBASE, CINAHL, PsycINFO, KoreaMED, KMbase, and KISS. The primary outcome will include the effect of the interventions on activities of daily living and behavioral and psychological symptoms of dementia. The literature search will be conducted based on search strategies designed for each database. The reviewers will independently assess the identified studies and extract the data. The risk of bias will be assessed and a meta-analysis will be conducted in accordance with the methodology for meta-analysis described in the Cochrane handbook. This systematic review will provide clinicians and policy makers with reliable evidence for developing and implementing nonpharmacological interventions for moderate to severe patients with dementia.

We report the first case of an angiomyomatous hamartoma (AH) of the popliteal lymph nodes (LNs) occurring in association with diffuse pigmented villonodular synovitis (PVNS) of the knee. AH is a rare benign vascular disease with a predisposition for the LNs of the inguinal region. Twenty-five cases of AH have been reported to date; however, the precise pathogenesis is still undetermined. In the present case, an open synovectomy revealed two of three popliteal LNs in close proximity to the extra-articular component of diffuse PVNS. These LNs demonstrated irregularly distributed thick-walled blood vessels in the hilum. These vessels extended into the medulla and cortex and were associated with haphazardly arranged smooth muscle cells in the sclerotic stroma. These findings are compatible with an AH. Our observations raise the possibility that AH of the popliteal LNs may represent an abnormal proliferative reaction against the inflammatory process caused by PVNS of the knee.
