From November 1987 to December 1995, 76 patients with periampullary cancer underwent resectional surgery in the department of surgery, Kosin medical college. The object of this study was to assess the prognostic factors of the periampullary cancer after pancreaticoduodenectomy. The postoperative mortality rate was 11.8%. Significant morbidity occurred in 39.5% of the patients, early reoperation was required in 9.2% of these patients, and the mean hospital stay was 21.7 days. Univariate analysis on all patients revealed that the survival rate was significantly related to the size of the tumor (> or =3.0 cm 13%, <3.0 cm 41.4%; p<0.05), lymph node status (invasion 8.7%, no invasion 31.8%; p<0.05) and the age of the patient (>50 20.5%, < or =50 34.5%; p<0.05). The site was less significant(distal CBD 27%, ampulla of Vater 16.7%, pancreas 9%, duodenum 2%; p>0.05). These results indicated that patients with a tumor size lesser than 3cm, without lymph node involvement, and under the age of 50 had a long term survival rate.

The Korea Food and Drug Administration (KFDA) revised the Health Functional Food Act in 2008 and extended the form of health functional foods to general food types. Therefore, this study was performed to investigate consumers' perceptions of the expanded form of health functional food and to predict consumption patterns. For this study, 1,006 male and female adults aged 19 years and older were selected nationwide by multi-stage stratified random sampling and were surveyed in 1:1 interviews. The questionnaire survey was conducted by Korea Gallup. The subjects consisted of 497 (49.4%) males and 509 (50.6%) females. About 57.9% of the subjects recognized the KFDA's permission procedures for health functional foods. Regarding the health functional foods that the subjects had consumed, red ginseng products were the highest (45.3%), followed by nutritional supplements (34.9%), ginseng products (27.9%), lactobacillus-containing products (21.0%), aloe products (20.3%), and Japanese apricot extract products (18.4%). Opinions on expanding the form of health functional foods to general food types scored 4.7 points on a 7-point scale, showing positive responses. In terms of the effects of medicine-type health functional foods versus generic health functional foods, the highest response was 'same effects if the same ingredients are contained' at a rate of 34.7%. For intake frequency by food type, the response of 'daily consistent intake' was 31.7% for capsules, tablets, and pills, and 21.7% for extracts. For general food types, 'daily consistent intake' was 44.5% for rice and 22.8% for beverages, which were higher rates than those for medicine types. From the above results, consumers had positive opinions of the expansion of health functional foods to generic forms but are not expected to maintain accurate intake frequencies or amounts. Thus, continuous promotion and education are needed for proper intake of generic health functional foods.

To investigate the effect of disposable contact lenses (CL) on the corneal epithelial healing, a prospective study of 30 myopic epikeratoplasties which were divided into 3 groups according to the method for promoting the corneal epithelial healing was conducted. The groups are consisted of 10 eyes with pressure patch, 10 eyes with Acuvue(R) disposable CL and 10 eyes with SeeQuence(R) disposable CL. Corneal epithelial healing was completed in the pressure patch, Acuvue(R) CL and SeeQuence(R) CL group at 3.4, 3.5 and 3.4 postoperative days, respectively. Corneal epithelial healing rate during postoperative 1, 2 and 3 days are 0.33, O.78, and O.44mm2/hour in pressure patch group, O.24, O.92 and O.37mm2/hour in Acuvue(R) CL group, and O.30, O.79 and O.38mm2/hour in SeeQuence(R) CL group respectively. From the above results, it is concluded that there was no statistically significant difference of the corneal epithelial healing time and rate between the pressure patching and disposable bandage CL wearing after myopic epikeratoplasty.

BACKGROUND: Pulmonary complications including pneumonia and pulmonary edema frequently develop in critically ill surgical patients. Lung ultrasound (LUS) is increasingly used as a powerful diagnostic tool for pulmonary complications. The purpose of this study was to report how LUS is used in a surgical intensive care unit (ICU). METHODS: This study retrospectively reviewed the medical records of 67 patients who underwent LUS in surgical ICU between May 2016 and December 2016. RESULTS: The indication for LUS included hypoxemia (n = 44, 65.7%), abnormal chest radiographs without hypoxemia (n = 17, 25.4%), fever without both hypoxemia and abnormal chest radiographs (n = 4, 6.0%), and difficult weaning (n = 2, 3.0%). Among 67 patients, 55 patients were diagnosed with pulmonary edema (n = 27, 41.8%), pneumonia (n = 20, 29.9%), diffuse interstitial pattern with anterior consolidation (n = 6, 10.9%), pneumothorax with effusion (n = 1, 1.5%), and diaphragm dysfunction (n = 1, 1.5%), respectively, via LUS. LUS results did not indicate lung complications for 12 patients. Based on the location of space opacification on the chest radiographs, among 45 patients with bilateral abnormality and normal findings, three (6.7%) and two (4.4%) patients were finally diagnosed with pneumonia and atelectasis, respectively. Furthermore, among 34 patients with unilateral abnormality and normal findings, two patients (5.9%) were finally diagnosed with pulmonary edema. There were 27 patients who were initially diagnosed with pulmonary edema via LUS. This diagnosis was later confirmed by other tests. There were 20 patients who were initially diagnosed with pneumonia via LUS. Among them, 16 and 4 patients were finally diagnosed with pneumonia and atelectasis, respectively. CONCLUSIONS: LUS is useful to detect pulmonary complications including pulmonary edema and pneumonia in surgically ill patients.

Background: Postoperative sore throat is a complaint after general anesthesia of multifactorial etiology. The laryngeal mask airway (LMA) reduces sore throat and discomfort during maintenance of the airway and make patients more comfortable. The purpose of this study was to compare effect of patient's position during operation on postoperative sore throat after the use of LMA. Methods: The fifty three patients were randomly divided into two groups. Group 1 (n=30) was underwent general anesthesia with supine position and group 2 (n=23) with prone position. After the LMA was positioned in the hypopharynx and the cuff inflated, fiberoptic laryngoscope was immediately passed down through the LMA. Number of attempts, degree of postoperative sore throat and other complications were also noted. Results: The incidence of postoperative sore throat after the use of LMA was 10% in supine position and 4% in prone position. But the difference between the groups was not statistically significant. All of the reported sore throats were rated as mild. Conclusions: Postoperative sore throat after the use of LMA is mild and the incidence is not affected by the prone position during the operation.

This study was performed to investigate the corneal epithelial healing time and rate according to the method for promoting the reepithelization after myopic epikeratoplasty. A prospective study was conducted on 30 myopic epikeratoplasties which were divided into 3 groups according to the method for promoting the epithelial healing. The groups consisted of 10 eyes with pressure patches, 10 eyes with Acuvue(R) disposable contact lens (CL) and 10 eyes with SeeQuence(R) disposable CL. The cornea epithelial healing time were 3.4, 3.5 and 3.4 postoperative days for the pressure patch, Acuvue(R) CL and SeeQuence(R) CL groups, respectively. The corneal epithelial healing rates during postoperative 1, 2, and 3 days were 0.33, 0.78, and 0.44 mm2/hour for the pressure patch group; 0.24, 0.92 and 0.37 mm2/hour for the Acuvue(R) CL group; and 0.30, 0.79 and 0.38 mm2/hour for the SeeQuence(R) CL group. These results suggest that a disposable contact lens may not hinder epithelial healing compared with a pressure patch.

Cases of incomplete Kawasaki disease (KD), wherein the patient does not fulfill the full diagnostic criteria for KD, are often detected in infants younger than 6 months of age. The clinical manifestations in infants with incomplete KD may resemble other infectious diseases, including meningitis. For this reason, clinicians may have difficulty differentiating incomplete KD from other infectious diseases in this population. Various neurological features are associated with KD, including aseptic meningitis, subdural effusion, facial nerve palsy, cerebral infarction, encephalopathy, and reversible corpus callosum splenial lesions on magnetic resonance imaging. We report a case of a 5-month-old girl with incomplete KD, associated with cerebrospinal fluid pleocytosis and an epidural fluid collection. Echocardiography indicated dilatation of the main coronary arteries. The girl made a complete recovery, with resolution of both the epidural fluid collection and coronary artery aneurysms. In this case, the child is well, and showed normal developmental milestones at the 7-month follow-up.

Purpose: This study was conducted to determine the factors affecting a hypothetical model of testing for general hospital nurses’ job embeddedness. Methods: Data were collected from August 20 to September 19, 2021, by a self-administered questionnaire answered by 428 general hospital nurses. The data were analyzed by SPSS and AMOS. Results: Nine of the hypothetical model’s 12 hypotheses were supported by the data collected from all participants. The test results indicate that ego resilience, subjective career success, and recovery experience from job stress directly affect participants’ job embeddedness. Nurses’ work environments were reported to affect ego resilience and subjective career success, while at the same time ego resilience and subjective career success affected the participants’ job embeddedness. Work-life balance was found to affect ego resilience and ego resilience affected subjective career success, and at the same time subjective career success directly affected participants’ recovery experiences from job stress and job embeddedness. Of these variables, subjective career success had the strongest direct effect on participants’ job embeddedness. Work-life balance affected the participants’ recovery experiences from job stress, and their recovery experiences from job stress were found to directly affect job embeddedness. Conclusion These results suggest that different management strategies to enhance hospital nurses’ job embeddedness should address nurses’ ego resilience, subjective career success, and recovery experiences from job stress.

OBJECTIVES: The purposes of this study were to identify the factors that affect the health-related quality of life (HRQoL) of the elderly with chronic diseases and to subsequently develop from such factors a prediction model to help identify HRQoL risk groups that require intervention. METHODS: We analyzed a set of secondary data regarding 716 individuals extracted from the Korea National Health and Nutrition Examination Survey from 2008 to 2010. The statistical package of SPSS and MATLAB were used for data analysis and development of the prediction model. The algorithms used in the study were the following: stepwise logistic regression (SLR) analysis and machine learning (ML) techniques, such as decision tree, random forest, and support vector machine methods. RESULTS: Five factors with statistical significance were identified for HRQoL in the elderly with chronic diseases: 'monthly income', 'diagnosis of chronic disease', 'depression', 'discomfort', and 'perceived health status.' The SLR analysis showed the best performance with accuracy = 0.93 and F-score = 0.49. The results of this study provide essential materials that will help formulate personalized health management strategies and develop interventions programs towards the improvement of the HRQoL for elderly people with chronic diseases. CONCLUSIONS: Our study is, to our best knowledge, the first attempt to identify the influencing factors and to apply prediction models for the HRQoL of the elderly with chronic diseases by using ML techniques as an alternative and complement to the traditional statistical approaches.
