Restriction of eye movement after surgery is an unusual but troublesome complication. A patient presented with a limitation of abduction after a 5 mm resection of medial rectus muscle and an 8 mm recession of lateral rectus muscle. Since the forced duction test was positive, restrictive factors were suggested to be implicated. A reparative operation was performed at the postoperative 9 month, and the forced duction test was negative after releasing the resected medial rectus muscle. The patient showed an improved abduction after recessing the resected muscle. Even after an uneventful surgery, resection of an extraocular muscle may cause restriction of ocular rotation caused by muscle scarring to the sclera or by an increased tightness of the muscle.

Purpose: The study was examined to investigate the influence of nurse manager and peer group caring behaviors on organizational socialization and nursing performance Methods: The subjects were 286 clinical nurses from a general hospital in S city. The collected data were analyzed using descriptive statistics, t-test, ANOVA, Pearson correlation and hierarchical regression analysis with the SPSS 25.0 program. Nurse manager and peer group caring behaviors, organizational socialization, and nursing performance were measured using organizational climate for caring scale, peer group caring interaction scale, organizational socialization and performance measurement scale for hospital nurses. Results There was no significant difference in organizational socialization between nurse manager and peer group caring behaviors. The significant predictors of nursing performance were position (β=-.26), nurse manager caring behaviors (β=.23), and peer group caring behaviors (β=.17). These variables explained 23% of the variance in nursing performance. Conclusion: The results suggest that it is necessary to increase both manager and peer group caring behaviors in order to improve nursing performance.

152 biopsy proven orbital lesions were seen during 1991-1995. Cystic tumors were the most frequent type of lesions, accounting for 36 cases(23.68%). Secondary tumors accounted for 17 cases(11.18%), lacrimal lesions 14 cases(9.21%), lymphoid tumors 14 cases(9.21%), inflammatory pseudotumors 13 cases(8.55%), peripheral nerve tumors 11 cases(7.24%), lipocytic and myxoid tumors 10 cases(6.58%), vasculogenic tumors 10 cases(6.58%), optic nerve and meningeal tumors 8 cases(5.26%), rhabdomyosarcomas 4 cases (2.63%), osteomas 3 cases (1.97%), metastatic tumors 3 cases (1.97%), histiocytic tumors 2 cases(1.32%), and other lesions 4 cases(2.63%). The most frequent primary orbital tumor was dermoid and most frequent maliganant tumor was maliganant lymphoma. In pediatric group, the most frequent primary orbital tumor was dermoid and most frequent maliganant tumor was rhabdomyosarcoma. Overall the frequency of maligant tumors was about 20%. Also this survey has a certain bias it will con tribute the recent classification and incidence of space-occupying lesions of the orbit in Korea.

PURPOSE: We compared the results of electromagnetic navigation assisted total knee arthroplasty (TKA) with that of conventional TKA from the viewpoint of the postoperative limb alignment and the implant position. MATERIALS AND METHODS: We retrospectively analyzed 115 consecutive total knee arthroplasties that were done between September 2006 and June 2007. There were 65 navigation assissted cases and 50 conventionally implanted cases. We analyzed the postoperative radiologic results, the clinical results over one year follow up after surgery and the range of motion (ROM). RESULTS: The postoperative mechanical axis deviation showed no significant difference between the two groups. However, the tibial zone, as assessed by Kennedy and White's method were at zone C for 60 cases (92%) in the navigation group and for 40 cases (80%) in the conventional group (p=0.01). On the coronal plane, the implant position of the femoral component was 89.4+/-4.1degrees in the navigation group and 87.6+/-4.3degrees in the conventional group (p<0.01), and the implant position of the tibial component was 89.7+/-1.1degrees and 91.9+/-1.8degrees in each group, respectively (p<0.01), and this shows the better result in the navigation group. CONCLUSION: Electromagnetic navigation assisted TKA had similar clinical results on the short-term follow up as compared with conventional TKA. However, it radiologically showed a more satisfactory position of the implant and it displayed superiority in locating the precise position of the femoral and tibial components, and especially on the coronal plane.

We report a case of urachal actinomycosis. The patient presented with complaints of micturition pain and a left lower abdominal mass with pain. Magnetic resonance imaging(MRI) showed the mass extending from the dome of the bladder to just beneath the rectus muscle. Exploration revealed a hard mass in the urachal cord, which was attatched to a part of sigmoid colon and the dome of the urinary bladder and extended to the umbilicus. The mass, urinary bladder dome, sigmoid colon and urachal cord were resected, and histopathological revealed actinomycosis.

The 4 bank mico-MLC (mMLC; Acculeaf, Direx, Isral) has been commissioned for clinical use of linac based stereotactic radiosurgery. The geometrical parameters to control the leaves were determined and comparisons between measured and calculated by the calculation model were performed in terms of absolute dose (cGy/100 MU). As a result of evaluating calculated dose for various field sizes and depths of 5 and 10 cm in water in the geometric condition of fixed SSD (source to surface distance) and fixed SCD (source to chamber distance), most of differences were within 1% for 6 MV and 15 MV x-rays. The penumbral widths at the isocenter were approximately evaluated to 0.29~0.43 cm depending on the field size for 6 MV and 0.36~0.51 cm for 15 MV x-rays. The average transmission and leakage for 6 MV and 15 MV x-rays were 6.6% and 7.4% respectively in single level of leaves fully closed. In case of dual level of leaves fully closed the measured transmission is approximately 0.5% for both 6 MV and 15 MV x-rays. Through the commissiong procedure we could verify the dose characteristics of mMLC and approximately evaluate the error ranges for treatment planning system.

PURPOSE:To evaluate the changes of QT dispersion (QTd) in CAPD patients serially from the period before the initiation of CAPD until several years after CAPD, and to find any associated factors. METHODS:We performed a retrospective cohort study with a total of 101 patients who initiated CAPD between 1990 and 1996. All data were recruited from the patients' medical records before CAPD initiation, within one year after CAPD, and between one and three years after CAPD. RESULTS:QTd and Corrected QTd (QTdc) values after CAPD did not show differences in the paired t-test of those before CAPD and within one year after CAPD. There was a definite correlation between the QTds before CAPD and that within one year after CAPD (r=0.530, p<0.001). In addition, the QTds from within one year after CAPD showed a correlation with those taken from one to three years after CAPD (r=0.487, p=0.019). Upon analysis of all-cause mortality, the change rate of QTd after CAPD initiation was revealed as a predicting factor along with the QTd, QTc max, and QTdc within one year after CAPD (RR=1.055, p=0.005). The change rate also remained a predictor of cardiovascular mortality (RR= 1.088, p=0.007). In a multivariate Cox regression, cardiomegaly and previous cardiovascular disease were revealed to be independent factors for the change rate of QTd. CONCLUSION:QTd in CAPD patients did not change after initiation of CAPD, and the change rate of QTd after CAPD initiation was revealed as a risk factor for both all-cause mortality and cardiovascular mortality.

This study was conducted to investigate the mothers' nutritional knowledge on weaning of 101 infants (8 for 4 mo, 44 for 5 mo, 45 for 6 mo, 4 for 7 mo) at a public health center of Incheon. Informations on the mothers' nutritional knowledge were obtained by questionnaires. In this survey 41.6% of infants were breast-feeding, 43.6% of them were bottle-feeding, and 14.9% of them were mixed feeding right after birth. The rate of breast-feeding right after birth was significantly higher in mothers of high school graduate than mothers of college/university graduate (p < 0.05). The infants of mothers graduated high school began to be weaned significantly earlier than the infants of mothers graduated college/university (p < 0.05). 95.1% of infants (n = 101) began to be weaned 4 to 6 months. 83.1% of infants were fed home-made weaning foods. 66.7% of infants were fed rice gruel, 18.5% of them were fruit juice, 6.2% of them were mixed grain, and 4.9% of them were commercially prepared weaning foods as their first supplementary foods. As main supplementary foods, 32.8% of infants were fed vegetable, 30.5% of them were rice gruel, and 27.7% of them were fruit juice. Mothers' nutritional knowledge related to weaning was significantly higher among mothers of college/university graduate than mothers of high school graduate (p < 0.05). 86.1% of mothers disagreed with the questionnaire in which breast-fed infants aged over 4 months needed to be fed iron sufficient food. For the improvement of nutritional status especially iron nutritional status of infants, nutritional education for mothers with weaning aged infants has to be increased and related programs have to be operated effectively.

BACKGROUND: Alveolar soft part sarcomas (ASPSs) are rare, histologically distinctive soft tissue sarcomas of unknown origin. Although ASPSs are characterized by a specific alteration, der(17)t(X;17)(p11;q25), the entire spectrum of genetic events underlying the pathogenesis of ASPS is unclear. Using array-based comparative genomic hybridization (array-CGH), we examined the DNA copy number changes in ASPS. METHODS: Array-CGH, composed of 4,030 clones, was performed in two samples of fresh frozen tumor tissues from a 29-year-old male and a 16-year-old female. RESULTS: We identified 16 commonly altered chromosomal regions involving 25 genes. Eleven altered regions were located on chromosome Xp (Xp22.33, Xp22.11, Xp11.3, Xp11.3-Xp11.23, Xp22.2, Xp22.12, Xp22.31, Xp22.32, Xp21.1, Xp21.3, and Xp11.4). Additional regions with an increased copy number were observed at 1q25.1, 7q35, 12p12.1, and 17p11.2. Loss was found in only one region of chromosome 22q11.23. Several genes located within the amplified region of Xp included GYG2, ARSD, ARSE, ARSH, UBE1, USP11, PCTK1, ARAF, SYN1, TIMP1, XK, PDK3, PCYT1B, PHEX, ARX, RPS6KA3, TMSB4X, TMEM27, BMX, and KAL1. CONCLUSIONS: This was the first application report of genome-wide copy number changes by BAC array-CGH in ASPSs. Our study showed unique genomic regions and new candidate genes that suggest a neural origin and are associated with tumor pathogenesis in ASPSs.

Tight junctions (TJs) form continuous intercellular contacts in intercellular junctions. TJs involve integral proteins such as occludin (OCLN) and claudins (CLDNs) as well as peripheral proteins such as zona occludens-1 (ZO-1) and junctional adhesion molecules (JAMs). TJs control paracellular transportation across cell-to-cell junctions. Although TJs have been studied for several decades, comparison of the transcriptional-translational levels of these molecules in canine organs has not yet been performed. In this study, we examined uterine expression of CLDNs, OCLN, junction adhesion molecule-A, and ZO-1 in canine. Expression levels of canine uterine TJ proteins, including CLDN1, 2, 4, 5, JAM-A, ZO-1, and OCLN, were measured using reverse transcription PCR, real-time PCR, and Western blotting, whereas TJs distribution was determined by immunohistochemistry. The mRNA and protein expression levels of OCLN, CLDN-1, 4, JAM-1, and ZO-1 were identified in the uterus. Immunohistochemistry demonstrated that TJs were localized to the endometrium and/or myometrium of the uterus. Our results show that canine TJ proteins, including CLDNs, OCLN, JAM-A, and ZO-1, were expressed in the canine uterus. Taken together, these proteins may perform unique physiological roles in the uterus. Therefore, these findings may serve as a basis for further studies on TJ proteins and their roles in the physiological or pathological condition of the canine uterus.
