To evaluate surgically induced astigmatism in cataract surgery, we studied retrospectively a series of 30 eyes with 6.5mm sutureless frown incision(Group 1) and 30 eyes with linear scleral tunnel incision and 3 interrupt sutures using 100 nylon(Group 2). In all cases phacoemulsifications were performed and posterior chamber lenses were implanted. Group 1 showed the against-the-rule astigmatism at postoperative 2 week, and then the change of the astigmatism was minimal and still against-the-rule by postoperative 6 week and 3 month. In contrast, Group 2 showed with-therule astigmatism at postoperative 2 week and then showed the against-the-rule by postoperative 6 week and 3 month. There was no significant difference in the proportion of corrected visual acuity of 0.5 or better between two groups at postoperative 3 month, while uncorrected visual acuity of 0.5 or better was 93.3% in group 2, and 30.0% in group 1 at postoperative 3 month. In this study, it was found that the pattern of surgically induced astigmatism and uncorrected visual outcome in cataract surgery were different according to incision and suture techniques.

We compared the diagnostic accuracy of the simple x-ray with that of the computed tomography, and analyzed the surgical results according to the timing of operation in 52 patients with suspected orbital blowout fractures who complained diplopia after midfacial trauma. Of all the cases, 40 orbital fractures were confirmed with CT and forced duction test and the remaining 12 patients were thought to have transient functional impairment because the clinical signs were resolved with time. CT detected all the 40 actual fractures, so the dignostic accuracy(100%) was higher than that of the simple x-ray(75%) which detected 30 fractures of the 40 actual fractures(p=0.001). We operated 19 patients who have persistent diplopia, enophthalmos of more than 2 mm, and large fracture defect, and there was significant improvement of symptoms and signs in patients on whom operations were performed within 2 weeks after trauma rather than after 2 weeks.

To evaluate the efficacy of the intracanalicular silicone plug in dry eye, we performed lower horizontal canalicular occlusion with the Herrick lacrimal plug Twenty-eight of the 34 eyes(81 %) were able to discontinue or reduce to occasional use of the instillation of artificial tears and the remaining unsatisfactory 6 eyes were investigated by radiologic study for silicone plug. In 2 eyes, the plugs were invisible in radiologic study and the canaliculi were occluded repeatedly. In one of the four eyes with their plugs in place, upper canaliculus was occluded additionally. By thorough evaluation of the status of the plug by radiologic study and secondary attempt. 31 of the 34 eyes(91%) were able to discontinue or reduce to occasional use of the instillation of artificial tears. The intracanalicular plug has no protruded portion out of the puntum, so complications such as reflex tearing, conjunctival irritation, and loss of plug through the punctum, were not occurred. Waters' view with soft tissue density was effective in demonstration of silicone intracanalicular plug.

Adherence is defined as 'the extent to which a patient's behavior corresponds with recommendations from a health care provider'. In all chronic diseases, including asthma, patient nonadherence to medical recommendations is common. In asthma, low rates of adherence to preventive medication are associated with higher rates of hospitalization and death. Many patients choose not to take their medication because they perceive it to be unnecessary or because they are concerned about potential adverse effects. Approximately one third of asthma patients have strong concerns about adverse effects from inhaled corticosteroids (ICSs). Clinicians must be prepared to work in an ongoing partnership with patients to ensure that they are offered a clear rationale as to why ICS are necessary and to address their concerns about potential adverse effects. This approach, based on a detailed examination of patients' perspectives on asthma and its treatment, and an open, nonjudgmental manner on the part of the clinician, is consistent with the idea of concordance. Both the efficacy of a medication and patient adherence to the therapeutic regimen influence the effectiveness of a treatment. This article will review the underlying reasons for patient nonadherence and describe the role played by clinicians in promoting optimal medicine management.

Diet is closely related to an economic level, but few studies have reported on the relationship between the economic level and eating habits, especially in college students. Therefore, this study was conducted to clarify differences in eating habits with a focus on processed foods according to allowance level in college students. This study was a cross-sectional survey of 500 college students using a questionnaire. The questionnaire consisted of general characteristics, eating behaviors, purchase of processed foods, and preference and intake frequency of processed foods. All subjects were classified based on monthly allowance: less than Won 300,000 (n=149), Won 300,000~400,000 (n=177), and more than Won 400,000 (n=124). All survey results were comparatively analyzed among the spending money groups. As the level of spending money of the subjects increased, the rate of skipping meals, eating out, and unbalanced diet increased (P<0.05). The reason for consuming processed foods was because they are easy to prepare. The factor considered the most when buying processed foods was price. However, these results showed no significant difference according to level of spending money. As spending money increased preference for retort, convenience, canned, and bottled foods significantly increased. Intake frequency of dairy products was lower, and the frequency of processed foods was significantly higher with more spending money. This study found that a higher level of monthly allowance in college students, was associated with higher rate of skipping meals, eating out, and unbalanced diet, and the preference and intake frequency of processed foods were also high. These results suggest that spending money level in college students, as an economic indicator, is relevant to intake of processed foods.

PURPOSE: This study was done to investigate the level of nursing students' awareness, attitude, safety climate, and performance of infection control, and to identify factors influencing performance. METHODS: The sample consisted of 239 nursing students from 5 nursing schools. Data were collected from November 15 to December 11, 2013 and analyzed by frequency, t-test, ANOVA, Pearson correlation coefficients, and multiple stepwise regression with SPSS/WIN 21.0. RESULTS: Of the participants, 216 (90.4%) had experienced contact with infectious diseases. The performance of personal hygiene was scored the highest followed by standard precautions, transmission precautions, and vaccination. There were significant correlations between awareness, attitude, safety-climate and performance. Awareness, safety-climate, attitude, contents of infection control education, and direct exposure to infectious disease collectively explained 30% of the variance in performance, and awareness was the most influential factor. CONCLUSION: The results indicate that performance of infection control by nursing students can be increased if awareness, safety climate, attitude, and contents of infection control education are improved, and exposure to infectious disease is decreased. These findings can be utilized to improve performance by developing education programs for infection control.

BACKGROUND: This study was performed to investigate the relationship between the extent of hippocampal resection and the postsurgical memory outcome in temporal lobe epilepsy (TLE). METHODS: In 36 patients with TLE, the longitudinal distances of pre-surgical hippocampus and post-surgical hippocampal remnant were measured on 3 mm thick coronal MRI images perpendicular to the long axis of hippocampus. Memory tests were performed before and 1 year after the surgery. The relationships of the extent of hippocampal resection (EHR) and the asymmetry index of Wada retention memory scores (WAI) with postsurgical memory outcomes were tested. RESULTS: The ratios of post-surgical/pre-surgical scores in immediate and delayed verbal memory and immediate, delayed and recognition visual memory were not significantly correlated with the EHR. Only verbal recognition memory was positively correlated with the EHR. In TLE of the dominant hemisphere, the ratios of post-surgical/pre-surgical scores of verbal and visual memories were not significantly correlated with the EHR, but the WAIs were significantly correlated with the delayed visual memory changes (p<0.05). In TLE of the non-dominant hemisphere, the ratios of post-surgical/pre-surgical scores of delayed verbal and immediate visual memory (in percentiles) were positively correlated with the EHR (p<0.05). However, a linear regression analysis showed that none of postsurgical memory subtypes were significantly correlated with the EHR. CONCLUSIONS: This study suggests that the extent of hippocampal resection itself does not have a significant relationship with the outcome of postsurgical memory in patients with mesial TLE.

This study was aimed to evaluate the ability of imaging parameters measured on dynamic contrast-enhanced magnetic resonance imaging (DCE-MRI), diffusion-weighted MRI (DWI) and positron emission tomography/computed tomography (PET/CT) to serve as response markers in breast cancer after neoadjuvant chemotherapy (NAC). In 20 patients with breast cancer, DCE-MRI and DWI using a 3 T scanner and PET/CT were performed before and after NAC. DCE-MRI was analyzed using an automatic computer-aided detection program (MR-CAD). The response imaging parameters were compared with the pathologic response. The areas under the curve (AUCs) for DCE-MRI using MR-CAD analysis, DWI and PET/CT were 0.77, 0.59 and 0.76, respectively. The combination of all parameters measured by MR-CAD showed the highest diagnostic performance and accuracy (AUC = 0.77, accuracy = 90%). The combined use of the parameters of PET/CT with DCE-MRI or DWI showed a trend toward improved specificity and negative predictive value (100%, 100%, accuracy = 87.5%). The use of DCE-MRI using MR-CAD parameters indicated better diagnostic performance in predicting the final pathological response compared with DWI and PET/CT, although no statistically significant difference was observed. The combined use of PET/CT with DCE-MRI or DWI may improve the specificity for predicting a pathological response.

PURPOSE: This study aimed to assess the usefulness of second-look ultrasounds performed on suspicious lesions found from breast MRIs which were taken as preoperative evaluations of breast cancer. MATERIALS AND METHODS: From May 2008 to July 2011, second-look ultrasounds were performed for 98 lesions in 80 patients that were initially detected on preoperative breast MRIs for known breast cancer. In this study, identification was made on the findings from second-look ultrasounds on the target lesions. The histopathological results were used to assess the effects of second-look ultrasounds on the treatment plans for patients, in the context of operation records. RESULTS: Among the total 98 lesions, sonographic correlation was made in 85 lesions (87%). In total, 82 lesions were identified with histopathological results. Among them were 18 malignancies (22%) and 64 benign lesions (78%). Sonographically-correlated lesions showed a higher prevalence for malignancy (20% [17/85]) than non-correlated lesions (8% [1/13]). From 44% (43/98) of the total target lesions, the unnecessary expansion of the extent of surgical resection was suppressible through second-look ultrasounds. CONCLUSIONS: Second-look ultrasounds subsequent to breast MRIs in patients with breast cancer are useful for preoperative evaluation and enables them to make the histopathological confirmation of suspicious lesions conveniently found from breast MRIs.
