PURPOSE: To investigate the actual adherence to treatment with preservative-free dorzolamide-timolol fixed combination (DTFC) eyedrops of primary open-angle glaucoma (POAG) patients by counting the number of unused single-dose units of DTFC. METHODS: This study included 34 POAG patients newly prescribed with preservative-free DTFC eyedrops (formulated in single-dose units). The enrolled patients were asked to bring the unused DTFC units on their next visit after 2 weeks of treatment with DTFC. On their second visit, they were asked to complete a questionnaire regarding the self-reported adherence and the number of unused DTFC single-dose units was counted. The actual adherence (%) was calculated by dividing the expected number of used DTFC units by the actual number of used DTFC units. The correlation between the self-reported adherence and the measured adherence was assessed. RESULTS: Twenty-nine (93.5%) patients answered they adhered to the medication by more than 90% and 2 (6.5%) answered they instilled the eyedrops at 80-90% of the dosing schedule. However, after counting the unused DTFC single-dose units, 9 (29.0%) patients showed an actual adherence of <90%. Moreover, the actual adherence of 3 (9.7%) patients was <60%. Unexpectedly, 4 (12.9%) patients showed the actual adherence exceeding 100% (196%, 1 patient; 107-132%, 3 patients). CONCLUSIONS: We demonstrated a large difference between the self-reported and the actual adherence to treatment by counting the unused single-dose units of eyedrops. Preservative-free topical anti-glaucoma medications (formulated in single-dose units) provide clinicians an opportunity to assess the actual adherence of glaucoma patients by counting the unused units of eyedrops.

Although many methods have been developed to correct the aging process of the head and neck, the correction of nasolabial folds still remains a difficult area. The difficulty of correcting nasolabial fold is due to the anatomical location and the difference of aging process. From March 2000 to February 2001, the authors operated on 10 aging face patients using face lift with SMAS and FAME(Finger-assisted malar fat pad elevation) technique. The authors repositioned the SMAS-platysma flap posterosuperiorly and used finger dissection of the malar fat pad enabling a 3-dimensional correction and repositioning of the fat pad without detachment of the zygomatic ligament. The finger dissection of the malar fat pad attached to the skin enables a more anatomical correction of the malar fat pad with a more natural looking layer and longer lasting results in addition to decreased hematoma, edema and postoperative pain compared to previous methods.

Various cancer types have been associated with cancer-related cerebral infarction. In this study, we describe the first case of cancer-related cerebral infarction in which the underlying disease was primary bone marrow lymphoma (PBML). A 79-year-old man presented with abruptly developed bilateral lower extremity weakness and confusion. Diffusion-weighted imaging on admission showed multiple cortical and subcortical embolic infarction lesions in multiple vascular territories. Diagnostic evaluations to determine the embolic source revealed no abnormalities. Laboratory testing demonstrated elevated D-dimer (2.59 μg/mL) but no other prothrombotic abnormalities. In suspicion of cancer-related stroke, we performed chest CT, abdomen CT, and FDG-PET to detect the hidden malignancy. Findings revealed no evidence of cancer; however, they did reveal signs of anemia (hemoglobin 9.0 g/dL). Bone marrow aspiration biopsy showed large atypical B cell involvement suggestive of high-grade B cell lymphoma. The patient was diagnosed with primary bone marrow diffuse large B-cell lymphoma initially presenting with ischemic stroke. Our case suggests that primary bone marrow cancer may be a candidate for the differential diagnosis of hidden malignancy in patients with suspected cancer-related stroke. Bone marrow biopsy may be essential for establishing an appropriate differential diagnosis in patients with abnormal hematologic findings.

Purpose: The aim of this study was to evaluate the physiological and behavioral effects of auditory stimulation with their own parent’s voice on heart rate and sleep states of very-low-birth-weight infants (VLBWIs) in neonatal intensive care unit. Methods: The data of 28 VLBWIs at the Ewha Womans University Mokdong Hospital between October 2016 and May 2017 was analyzed. They were exposed to sounds similar to those of mothers’ heartbeat they had heard in the uterus and their own parent’s voice. Heart rate was assessed as the physiological responses and sleep state of infants as behavioral response. The sleep states were categorized into six states. The music intervention program was provided twice a week. Results: Twenty-eight babies with an average gestational age of 28 weeks (average birth weight of 1.09 kg) had undergone the sessions (average of 16 times) average of 16 times. During the initial period, there were no meaningful differences of the heart rates measured by the physiological functions before and after the sessions. However, as we move to the adaptive phase, the average heart rate was 156.96±12.22, and the pre-discharge was 149.11±12.01, which indicates meaningful differences (P<0.05). Infants’ behavioral function was statistically insignificant. Conclusion The music intervention techniques in the neonatal intensive care unit environment in Korea have provided positive influence to VLBWIs' physiological reactions. We were not able to come up with the relevant indicators during this phase of the study but we do plan to announce the future study results after indexing the observation results.

SV40 large T antigen, a viral oncoprotein, is known to immortalize human diploid fibroblast by soaking up cellular RB and p53, but its frequency is extremely low. Additional genetic alteration is necessary for single-step immortalization. We attempted to find out what this alteration is by overexpressing cellular signal mediator genes; c-myc and cyclin D frequently amplified in many cancer cells. Overexpression of cyclin D did not affect the immortalization, but, overexpression of c-myc along with T antigen could immortalize normal human diploid fibroblast. Several cellular markers tested during immortalization process showed that p21, a cyclin-dependent kinase inhibitor and a marker of cellular senescence, disappeared in the life span-extended cells by T antigen and in the immortalized cells by c-myc. p21 was, however, elevated in the senescent cells and in the cells of crisis. Interestingly, p16 was upregulated whenever T antigen is overexpressed. Telomerase activity was also activated only in the immortalized cells. These results suggest that overexpression of c-myc contributes to immortalization of human diploid fibroblast by activating telomerase activity and suppressing p21 activity.

PURPOSE: The purpose of this study was to evaluate the effectiveness of a health promotion program utilizing action planning strategy for young adults. METHODS: A non-equivalent control group pre-post-test design was used. One hundred three university students participated in the study. Participants in the experimental group (n=51) were provided the health promotion program utilizing action planning strategy for five weeks. The program consisted of weekly sessions that included action planning and group feedback. The control group (n=52) was provided with health information every week for 5 weeks. Program outcomes, including self-efficacy, physical activity health behaviors, total exercise time per week, daily cigarette consumption, frequency of alcohol drinking per month, nutritional health behaviors, and subjective health status, were assessed at baseline and at follow-up after 5 weeks. RESULTS: The participants in the experimental group demonstrated significant increases in self-efficacy, physical activity health behaviors, weekly exercise time, and nutritional health behaviors and significant decreases in daily cigarette consumption than those in the control group. CONCLUSION: The health promotion program utilizing action planning strategy is a brief and effective intervention to promote health behaviors among young adults. Further investigation is warranted to assess the program's effectiveness among other age groups and populations at high risk for chronic illness.
