STATEMENT OF PROBLEM: While patient-centered outcomes are usually not reported, these may represent major aspects of the implant success for the patient. Use of a well-designed patient survey form can be an invaluable asset to the implant practitioners. PURPOSE: The objective of this study was to investigate patient satisfaction after implant therapy by means of a questionnaire. MATERIAL AND METHODS: South Korean patients (n = 100), who visited the dental examination center of Soon Chun Hyang university hospital, were asked to fill out the satisfaction questionnaire regarding aspects of cost, comfort, esthetics, chewing, gingival health, food impaction, phonetic aspect, screw loosening, and general satisfaction. Responses to statements were given on the Likert response scale. Four experimental groups of patients were distinguished with various location (A1, A2, A3), year (B1, B2, B3), number of implant replacements (C1, C2, C3), and treatment cost (D1, D2, D3). The reliability of the response scales was measured by calculation of its internal consistency, expressed as Cronbach's alpha. The scales were distinguished by means of factor analysis method. Possible differences in scale scores among the groups were assessed by One-way ANOVA (alpha = 0.05). RESULTS: Patients responded to most of the statements with high satisfaction. But the mean scale score of statement about cost was low. After the verification of internal consistency and factor analysis, five components, e.g. general satisfaction, comfort, chewing efficiency, esthetics, and phonetic aspect were grouped together. These components could be explained with common meaning and the first factor was named as 'general satisfaction' . Differences in patient satisfaction on the scale with esthetics were present between patients who have been wearing the implant prosthesis less than three years and those more than seven years (B1 < B3). CONCLUSION: The patients were generally satisfied with the outcome of implant treatment. But the patients' major complaint was high cost and while the statistically significant difference was not shown, the satisfaction scale about food impaction and esthetics was low. So the continuing efforts to make improvements about these problems are needed for the implant practitioners.

Amidarone hydrochloride, benzofuran derivatives, particularly effective for the treatment of arrythmias by prolong the duration of the action potential in all cardiac-conducting tissues. We studied the 25 patients with typical amiodarone keratopathy, retrospectively. In 25 patients, ten patients developed grade 1, eleven patients developed grade 2, and four patients developed grade 3 keratopathy. They complained of decreased best corrected visual acuity(1 patient), halos(1 patient), hypothyroidism(3 patients), pulmonary toxicity(2 patients), thpatic dysfunction(5 patients) and sleep dusturbance(3 patients). Therefore ophthalmologists should be alert for the complications of amiodarone and regular careful slit-lamp examination will be helpful in minimizing amidarone toxicity.

We used the fluorophotometry to investigate the corneal epithelial barrier function after excimer laser photorefractive keratectomy (PRK). Twenty-five eyes of 21 subjects (13 women, 8 men) underwent PRK to correct rnyopia. Corneal epithelial healing time was measured and corneal epithelial permeability to sodiurn fluorescein was evaluated by fluorophotoinetry at I, 2, and 3 weeks after surgery. The corneal epithelial permeability increased significantly 1 week after surgery and returned to preoperative level 2 weeks after surgery. The permeability differences according to epithelial healing days and corrected diopters were not statistically significant(p>0. 05). These results suggest that PRK delays complete reconstruction of corneal epithelial barrier function. The corneal epithelium regained its functional barrier 2 weeks after PRK in patients, so, at least, during the first 2 weeks, care should be taken to miniinize further epithelial trauma from topical inedication or surgical manipulation.

Objectives: This paper aimed to provide an in-depth analysis of the factors influencing the dietary habits of male and female workers at a facility in Gwangju and their awareness of the same. Methods: A total of 32 workers were divided into eight groups based on work type, gender, and age, and focus group interviews (FGIs) were conducted. The FGIs included cognitive, behavioral, and environmental questionnaires based on dietary habits and the social cognitive theory. The interviews were analyzed by subject and sub-subject using audio recordings and transcriptions. Results: Male workers in the concerned company favored meat while female workers preferred vegetables, yet by and large, the preferences were irregular. Male workers living alone frequently ate ready meals and female workers often skipped meals. An analysis of the factors influencing the study subjects’ dietary habits from the cognitive, behavioral, and environmental perspectives showed that the main factors negatively affecting their dietary habits were shiftwork, living alone, and drinking. Workers were unaware of these factors and their poor eating habits. Instead, male workers complained of poor cooking skills, while female workers complained of loneliness. Workers thus appeared to need the support of nutrition education and a counseling assistant to cope with this situation. Conclusions The study identified the fact that the absence of nutrition education left the workers unaware of their poor eating habits. The workers would need counseling and support to help them build healthy dietary habits. It would also be necessary to focus on raising the workers’ cognitive awareness of dietary habits and enhancing their behavioral ability to cope with bad eating habits through nutrition education that reflects the reality of their situation.

Behavioral and psychological symptoms of dementia are major components of Alzheimer’s disease. In this study, we aimed at investigating the prevalence and severity of behavioral and psychological symptoms of dementia in very mild to mild Alzheimer’s disease. Forty-four patients with Alzheimer’s disease who visited the neurology outpatient clinic of Seoul Medical Center were included. A trained neurologist or a supervised test technician administered the neuropsychological test, the Seoul Neuropsychological Screening Battery including Mini Mental State Examination and Clinical Dementia Rating. The instrument used for assessing behavioral and psychological symptoms of dementia was Neuropsychiatric Inventory-Questionnaire. In order of prevalence, apathy, depression, irritability, anxiety, and agitation were the most common symptoms occurring in very mild-to-mild Alzheimer’s disease group. The prevalence and severity of behavioral and psychological symptoms of dementia were found to be in positive correlation with the Clinical Dementia Rating scores. Behavioral and psychological symptoms of dementia are found even in the very early stage of Alzheimer’s disease, apathy and depression being the most common symptoms. Physicians should be aware of this when managing dementia patients.

BACKGROUND: Recent advances in stroke therapies require patients to be treated very early after the onset of symptoms. To reduce the delay in time upon stroke and arriving at the hospital, we assessed the time delay, stroke recognition, and awareness before and after a public education program designed to increase recognition and awareness. METHODS: Prospective standardized and structured interviews were performed in 155 patients with ischemic stroke who were admitted to the Severance hospital before and after the public education program. The educational program included local newspaper articles, distribution of pamphlets, and lectures to 119 emergency care teams. Time delay, variable factors, stroke recognition, and stroke awareness of patients were then assessed (75 pre-education and 80 post-education groups). RESULTS: 52% of the pre-education group and 52.5% of the post-education group arrived at the hospital within 24 hours. Those who arrived within 3 hours were only 21.3% and 15% respectively. A direct visit to the hospital and a cardioembolic infarction appeared to be associated with a shorter time delay. About half of the patients recognized their symptoms as a stroke before a diagnosis was made by a doctor. Most of them had known that a stroke should be treated urgently. However, the stroke recognition and awareness was not associated with an early arrival, which suggests that their knowledge was not solid. The efforts to inform the public using local newspaper articles and pamphlets geared towards the local residents for the limited time period was not effective in shortening arrival times. CONCLUSIONS: Many of the stroke patients did not arrive within the therapeutic time window. Our findings suggest that extensive and multi-directional campaigns should be performed to reduce the time delay. Our findings also suggest that educational aims should include the need for the rapid treatment of stroke and a therapeutic time window as well as stroke recognition.

PURPOSE: The benefits of thrombolytic treatment are time-dependent. We developed a smartphone application that aids stroke patient self-screening and hospital selection, and may also decrease hospital arrival time. MATERIALS AND METHODS: The application was developed for iPhone and Android smartphones. Map data for the application were adopted from the open map. For hospital registration, a web page (http://stroke119.org) was developed using PHP and MySQL. RESULTS: The Stroke 119 application includes a stroke screening tool and real-time information on nearby hospitals that provide thrombolytic treatment. It also provides information on stroke symptoms, thrombolytic treatment, and prescribed actions when stroke is suspected. The stroke screening tool was adopted from the Cincinnati Prehospital Stroke Scale and is displayed in a cartoon format. If the user taps a cartoon image that represents abnormal findings, a pop-up window shows that the user may be having a stroke, informs the user what to do, and directs the user to call emergency services. Information on nearby hospitals is provided in map and list views, incorporating proximity to the user's location using a Global Positioning System (a built-in function of smartphones). Users can search for a hospital according to specialty and treatment levels. We also developed a web page for hospitals to register in the system. Neurology training hospitals and hospitals that provide acute stroke care in Korea were invited to register. Seventy-seven hospitals had completed registration. CONCLUSION: This application may be useful for reducing hospital arrival times for thrombolytic candidates.

PURPOSE: Vitamin D status is associated with several chronic diseases related to obesity. In this study, we evaluate the nutritional status of vitamin D and its relation to obesity indices in Korean women. METHODS: A total of 156 healthy women participated. Vitamin D status (serum 25-OH-vitamin D3 level) and obesity indices (body mass index, body fat mass, waist-hip ratio, and body fat percentage etc.) and serum lipid profiles and serum adipokine (leptin and adiponectin) levels were analyzed. RESULTS: The 25(OH)D3 level showed an extremely skewed distribution from 4.1 ng/ml to 24.4 ng/ml and mean 25(OH)D3 level was 9.0 +/- 4.0 ng/ml. With cut-off level for vitamin D deficiency (< 12.0 ng/ml), insufficiency (12-19.9 ng/ml) and sufficiency (> or = 20 ng/ml), 77.6%, 19.2%, and 3.2% of subjects showed vitamin D deficiency, insufficiency, and sufficiency status, respectively. The 25(OH)D3 level showed positive correlation with weight (r = 0.2461, p < 0.01), body mass index (r = 0.2913, p < 0.001), body fat contents (r = 0.1691, p < 0.05), fat free mass (r = 0.2330, p < 0.01), and waist hip ratio (r = 0.1749, p < 0.05) after adjusted by age. The 25(OH)D3 level showed no significant correlation with serum lipid profiles and adipokine levels. CONCLUSION: Most subjects (76.6%) in this study, who had a vitamin D deficient status and serum 25(OH)D3 level, showed positive correlation with several obesity indices, however further research based on a large Korean population is needed to confirm the relationship.

The diagnosis of gastrointestinal stromal tumor (GIST) has become relatively common in recent years, but little is known about its association with other malignancies. We present a rare case of successfully treated metachronous GIST and colon cancer with concurrent FOLFOX (5-fluorouracil, leucovorin, and oxaliplatin) chemotherapy and imatinib. A 63-year-old man presented with abdominal pain that had started 2 weeks ago, and endoscopic ultrasonography showed masses that were compatible with GIST on the duodenum. He underwent Whipple surgery. One year after the GIST diagnosis, two liver masses were found on abdominal computed tomography images taken for surveillance. A liver biopsy showed metastatic adenocarcinoma, not GIST. Colonoscopy was then performed to identify the primary site of the metastatic adenocarcinoma in the liver, and sigmoid colon cancer was found. He received 12 cycles of adjuvant FOLFOX concurrently with adjuvant imatinib. There were no serious adverse events of grade 3 or higher from either imatinib or chemotherapy. He has completed adjuvant imatinib and FOLFOX chemotherapy and there is no evidence of disease recurrence. When a synchronous or metachronous tumor is found in a GIST patient, the clinician should keep in mind the possibility of another primary tumor of different histopathology, as well as GIST recurrence.

The combination of pure motor hemiplegia and horizontal gaze palsy is a rare but identifiable lacunar syndrome. Among horizontal gaze palsies, one-and-a-half syndrome and abducens nerve palsy are reported to be associated with pure motor hemiplegia in pontine lacunar infarction. Although conjugate lateral gaze palsy is also hypothesized, pure motor hemiplegia with conjugate lateral gaze palsy has never been reported. We present a 75-year-old man who showed right hemiparesis and impaired left horizontal conjugate eyeball movement. Both the findings of the brain CT scan and those of the MRI study were consistent with a small infarction in the left midpontine tegmentum. Magnetic resonance angiography revealed no stenotic narrowing of the vertebrobasilar artery. Radiological findings suggested that pure motor hemiplegia with conjugate lateral gaze palsy, in our patient, might have been produced by the occlusion of a single penetrating branch of the basilar artery.
