Glioblastoma multiforme (GBM) is located most frequently in the cerebral hemispheres. Glioblastoma presenting as an extraaxial mass of cerebellopontine angle (CPA) is very rare in adults. We report a rare case of GBM arising in the CPA. The patient was a 71-year-old female, who complained of progressive gait disturbance and poor memory. Initial magnetic resonance imaging (MRI) revealed a 1.4×1.3 cm mass in the left CPA, with broad base to the petrous bone, showing homogenous enhancement. Follow-up MRI showed a rapid increase in size of mass (2.7×2.2 cm) with a necrotic portion. A stereotactic biopsy was done under the guidance of navigation system, and the histopathologic diagnosis was GBM, World Heath Organization grade IV. Further surgical resection was not performed considering her general condition, and the patient underwent concurrent chemotherapy with radiation therapy. Although rare, the possibility of glioblastoma should be included in the differential diagnosis of atypical CPA tumor.

The Parasitological investigation on the encysted metacercariae in brackish water fish, Tribolodon taczanowskii, in the downstream of Hyungsan river which is located in Kyungpook Province of Korea, were carried out serially and the following results were obtained. Metacercariae of Pseudexorchis major were found in six fishes(15.8 per cent ) out of 38 examined. Parasitic frequencies of the encysted metacercaria of Psedexorchis major in Tribolodon taczanowskii were 15.8 per cent (6 out of 38) in the scale, 10.5 per cent (4 out of 38) in the fin, 13.2 per cent (5 out of 38) in the gill, 10.5 per cent (4 out of 38) in the oral cavity and 7.9 per cent (3 out of 38) in the flesh. The worms were identified as Pseudexorchis major (Hasegawa, 1935) Yamaguti, 1938 by morphological studies on the metacercariae, excysted metacercariae, adults and eggs, and compared with prereported Pseudexorchis species.

BACKGROUND: Hemodynamic instability is one of the main concerns for anesthesiologists during orthotopic liver transplantation (OLTX). The most troublesome event would be an increase of central venous pressure associated with sudden right ventricular (RV) filling without any change in heart contractility. An acute increase in RV outflow pressure depresses RV contractility and eventually causes overt RV failure. To avoid such disaster, it would be wise to evaluate right heart pressure/volume relationship and assess contractility when anticipating acute increase of pressure in right heart chamber. METHODS: RV function was assessed in 15 patients undergoing OLTX. RV function was monitored using an ejection fraction catheter and a monitor. Complete hemodynamic profile was obtained on regular intervals. Statistical analysis was performed using ANOVA for repeated measures. Correlation between variables were determined by simple regression analysis and ANCOVA. RESULTS: RV end-diastolic volume was in the range of supranormal values. No correlation was observed between right atrial pressure and RV end-diastolic volume index (RVEDVI). There was a significant correlation between stroke index and RVEDVI. RV ejection fraction and E-single were relatively constant throughout the procedure. There was weak negative correlation between E-signle and RVEDVI. CONCLUSION: RV function appeared to be well preserved during OLTX. However, RV contractility tends to decrease in response to RVEDV increase because RVEDV of endstage liver disease might increase to their maximal value. Right heart filling pressure was less reliable clinical indicator of RV preload.

Tretinoin(all-trans retinoic acid) is a metabolite of vitamin A and it is useful in the treatment of photoaging skin. Photoaging skin is characterized by wrinkles, mottled pigmentation, dry and rough skin, and loss of skin tone. Current use of topical tretinoin mainly acts on the epidermis, requires a long period to obtain the desired results and may cause skin hyperpigmentation. A combination of topical and injectable tretinoin has been used to reduce the treatment period as a result of its potentialized effect on the dermis when compared to graditional topical cream use. in this study, we observed histologic alterations in 5 white rabbits after using 0.05% topical tretinoin cream and 0.1% injectable tretinoin. Tretinoin was treated on the rabbits ears-group 1 and 2 on the right ear for study 1, and group A and B on the left ear for study 2. Study 1 was done to differentiate whether the dermal thickening is due to the simple physical stretching of dermis by intradermal injection, or whether it is duer to the histologic change by tretinoin. In group 1, saline was injected intradermally and in group 2, tretinoin was injected intradermally. Study 2 was done to compare the dermal thickening between the topical tretinoin cream treatment group (group A) and the combined topical and injectable tretinoin group (group B). Injection was done once a week immediately followed by 340nm blue light skin exposure. These treatment were done for 12 weeks. We harvested skin stripe from all group, group 1 and 2, and group A and B respectively, after 2, 6, and 12 weeks after treatment. Histologic differences were observed and measured. Dermal thickening was observed in group 2 and in group B(p<0.05). The results showed that intradermal injection of tretinoin mainly acts on the dermis and potentialtes the effect on photo-aging skin and fine wrinkles.

OBJECTIVE: Fibromyalgia (FM) is a rheumatic disorder characterized by widespread bodily pain, tenderness at multiple sites, and fatigue. It has a major impact on the quality of life. However, there has been no report regarding the health-related quality of life (HRQOL) in Korean patients with FM. The objective of this study was to assess the HRQOL and the correlation among each measurement and to identify the predictors for HRQOL in Korean patients with FM. METHODS: The HRQOL and clinical parameters were assessed by Short Form Health Survey-36 (SF-36), EuroQol 5 Dimensions (EQ-5D), time trade off (TTO), standard gamble (SG), Centers for Epidemiologic StudiesDepression (CES-D), social support, self-efficacy scale, Fibromyalgia Impact Questionnaire (FIQ), and tender points, respectively, from 104 outpatients with FM. RESULTS: Of the 104 subjects, 99 (95.2 %) were women with mean (+/-SD) age of 49.2 years (+/-11.1). The mean (+/-SD) years of disease onset was 8.06 (+/-7.38). The mean (+/-SD) scores of SF-36 global, mental component summary (MCS) and physical component summary (PCS) were 41.6 (+/-19.8), 47.4 (+/-25.0), and 43.5 (+/-23.7), respectively. The SF-36 GH, PCS, MCS scores of FM patients were lower than that of healthy controls (p<0.001). The mean (+/-SD) EQ-5D utility and visual analog scale (VAS) were 0.52 (+/-0.32) and 55.6 (+/-19.4). The mean (+/-SD) scores of the TTO and SG were 0.49 (+/-0.44) and 0.47 (+/-0.42). The mean (+/-SD) scores of CES-D, self-efficacy scale, social support and social network were 16.0 (+/-10.2), 55.9 (+/-19.4), 2.37 (+/-0.27), and 2.07 (+/-0.58), respectively. The mean (+/-SD) scores of FIQ was 46.4 (+/-17.7). The FIQ total score was negatively correlated with the scores of SF-36 GH, MCS, PCS, EQ-5D utility and VAS, TTO, SG, social support, social network, and self-efficacy scale (r=-0.63, r=-0.60, r=-0.48, r=-0.59, r=-0.56, r=-0.32, r=-0.27, r=-0.25, r=-0.31, r=-0.54, respectively. all p's<0.001), and positively correlated with the CES-D (r=0.67, p<0.001). In multivariate models, the predicting variables of SF-36 GH and PCS were age, FIQ, and self-efficacy and the predicting variables of SF-36 MCS were income, FIQ, and social support. CONCLUSION: These results suggest that the HRQOL in Korean patients with FM is lower than healthy subjects. In a simple correlation analysis, FIQ, CES-D, social support, and self-efficacy were meaningful variables correlated with HRQOL. In multivariate model, age, FIQ, and self-efficacy were independent variables correlated with HRQOL. Therefore, the efforts to improve HRQOL in Korean patients with FM should be designed to improve the self-efficacy and depression in addition to conventional approach.
