Purpose: To evaluate the therapeutic effect of intense pulsed light (IPL) therapy for the treatment of dry eye with meibomian gland dysfunction (MGD). Methods: A retrospective study was conducted for 124 eyes of 62 patients with dry eye with MGD who underwent 3 IPL sessions at 3 week intervals. All patients underwent clinical examination before and during treatment as well as 3 weeks after the last treatment. Measured parameters include Meibomian gland expressibility (MGE), Meibomian gland secretion (MGS) score, tear meniscus height (TMH), noninvasive break-time (NIBUT), corneal staining score (Oxford scale), Ocular Surface Diseases Index (OSDI), and subjective ocular discomfort improvement. Results: Meibomian gland function (MGE, MGS), ocular surface parameters (NIBUT, Oxford scale) and dry eye symptom (OSDI, subjective ocular discomfort improvement) of patients were significantly improved from baseline to after the 1st IPL, and the 3rd IPL weeks (p < 0.05 for all). However, no significant difference in TMH was observed. Conclusions This study showed that IPL was a useful and effective treatment in patients of dry eye with MGD to stabilizes the tear film and improve meibomian gland function and ocular symptoms.

Despite its fall in incidence, gastric adenocarcinoma remains a common disease with dismal prognosis worldwide. A better understanding of its tumorigenesis and biologic properties of tumor cells related to invasion and metastasis is crucial to improving diagnosis and treatment. Conflicting results concerning the relationships between overexpression of PAI-1, c-erbB2, and p53 protein and biologic behavior of gastric carcinoma have been noted. The aim of this study was to evaluate the value of overexpression of PAI-1, c-erbB2, and p53 protein as prognostic factors in gastric adenocarcinoma. Overexpression of PAI-1, c-erbB2, and p53 protein by immunohistochemistry was correlated with variable clinicopathological parameters and patients' survival in 80 cases of gastric adenocarcinoma. Overall PAI-1 expression rate was 63.7% (51/80) and higher in advanced cancer (p=0.0003) and nodal metastasis (p=0.003) groups. Overall c-erbB2 expression rate was 43.8% (35/80) and higher in antral (p=0.03), differentiated (p=0.001), intestinal (p=0.0007), and expanding (0.03) groups. The p53 protein overexpression was 37.5% (30/80) and higher in early cancer (p=0.02), differentiated (p=0.006) and intestinal groups (p=0.009). Patients with PAI-1, c-erbB2, and p53 protein positive tumors tended to have poorer survival rates than patients with PAI-1, c-erbB2, and p53 protein negative tumors, but the difference was not statistically significant (p=0.25, 0.37, 0.52). Our data indicated that PAI-1 overexpression is one of the poor prognostic factors in gastric adenocarcinoma and c-erbB2 and p53 protein seem to be involved in the early stage of carcinogenesis of intestinal type-gastric adenocarcinoma.

Purpose: This study aimed to investigate the influences of teamwork and job burnout on patient safety management activities (PSMA) among operating room nurses. Methods: We collected cross-sectional data from 144 operating room nurses with at least 1 year of clinical experience. Teamwork had five subscales (team structure, leadership, situation monitoring, mutual support, and communication) and burnout had two subscales (exhaustion and disengagement). We used descriptive statistics, t-tests, analysis of variance, Pearson’s correlation coefficients, and multiple linear regression. Results: PSMA had significant positive correlations with all subscales of teamwork and had a significant negative correlation with disengagement. Multiple regression analysis revealed that gender, clinical career in operating room, number of patient safety education, accreditation evaluation experience, team structure, and situation monitoring were associated with PSMA. Specifically, we found significant positive associations of team structure (β=.31, p<.001) and situation monitoring (β=.23, p=.039) with PSMA. Disengagement was not associated with PSMA after adjusting for confounders despite a significant correlation. Conclusion To improve operating room nurses’ PSMA, it is important to improve their awareness of the team structure and their ability to monitor the operating room situation.

Matrix producing carcinoma of the breast is a variant of heterologous metaplastic carcinoma which is defined as "overt carcinoma with direct transition to a cartilagenous and/or osseous stromal matrix without an intervening spindle cell zone or osteoclastic cells". This tumor is very rare, occuring in less than 0.2% of total breast carcinoma, but the prognosis is better than other metaplastic carcinoma. We experienced a case of fine needle aspiration(FNA) cytologic finding of matrix producing carcinoma of the breast. A 75-year old woman, who presented a right huge breast mass(9x8cm) during 10months, was examined. Mammography reveals right lateral mass with even density without calcification. Breast ultrasonography shows multifocal hypoechogenic cystic change in the huge mass, suggesting resolving hematoma or carcinoma or sarcoma with necrosis. On cytologic finding of FNA, myxoid matrix was the dominant feature and the rest of the material was composed of scanty isolated atypical cells with large irregular nuclei. The histologic finding was moderately differentiated adenocarcinoma with abundant cartilagenous matrix and focal squamous metaplasia.

PURPOSE: This study examined the frequency of sugar-sweetened beverage consumption in Korean adolescents and the major factors influencing the excessive consumption of sugar-sweetened beverages, such as sociodemographic characteristics, health-related behaviors, psychological characteristics, and dietary habits. METHODS: The analysis was performed using the data from the 2017 Korean Youth Risk Behavior Web-based Survey. The subjects included in the analysis were 30,885 middle school students and 31,391 high school students, totaling 62,276. The frequency of sugar-sweetened beverage consumption was calculated by summing the consumption frequencies of soda, high caffeine or energy drinks, and sweet beverages over the last 7 days. The Rao-Scott chi-square test, reflecting information on the sampling design, was used to test the differences in the rate of sugar-sweetened beverage consumption according to each factor. Logistic regression analysis was performed to examine the factors influencing the excessive consumption of sugar-sweetened beverages. RESULTS: The rate of sweetened beverage consumption was higher in boys than in girls, in high school students than in middle school students, in students whose father's education level was lower, in those whose subjective academic performance was lower, and in those who smoked or consumed alcohol. In addition, the rate of sugar-sweetened beverage consumption was higher in those who experienced severe stress, suicidal ideation, sadness, or a sense of despair. The rate of sugar-sweetened beverage consumption was also high in those who skipped breakfast; who frequently consumed fast foods, ramen, or snacks; and who frequently ate meals at convenience stores, supermarkets, or school stores. CONCLUSION: The rate of sugar-sweetened beverage consumption in Korean adolescents is related to various factors, such as sociodemographic characteristics, health-related behaviors, psychological characteristics, and dietary habits.

Mycoses refer to infectious diseases caused by fungi. Fungal infections are rare and mainly occur as opportunistic infections in immunocompromised patients. Candida species are the most common cause of mycosis; however, members of the order Mucorales or genus Aspergillus may also cause serious fungal infections in immunocompromised hosts. Fungal infections of the gastrointestinal (GI) tract can be asymptomatic or may present with abdominal pain, bloating, diarrhea, or GI bleeding. Although rare, thorough understanding of fungal infections of the upper GI tract encountered in real-world clinical settings can enable early diagnosis and prompt initiation of treatment to improve patient prognosis.

BACKGROUND/AIMS: Along with the expansion of the field of laparoscopic surgery, many laparoscopic instruments have been developed and these all together made laparoscopic surgery possible in many operative procedures which used to be considered impossible to be done using a laparoscope. Suturing is a technique quite often required during laparoscopic surgery and so far we have used imported suture material. In this article, we have compared the safety and harmfulness of suture material developed domestically in Korea with those imported using house rabbits. METHODS: A total of 40 white house rabbits from New Zealand weighing 3.0-3.4 Kg were used from July 1, 2000 until April 30, 2001. Under general anesthesia, we created a pneumoperitoneum using a veress needle with a pressure of 10 mmHg followed by insertion of a 5mm laparoscope right above the umbilicus and two 5mm trocars were inserted in the right and left midclavicular lines 5cm below the costal margin. After perforating the pylorus of the stomach using laparoscopic scissors, we sutured two sites using Laploop and then perforated the body of the stomach and again sutured two sites but this time using Vicryl #3-0 for comparison with Laploop. 10 house rabbits were sacrificed each on post operation days 10, 20, 30 and 40 and tissues obtained from those house rabbits were compared using the Sewell method. RESULTS: Suturing and ties were done without any problems and there were no postoperative complications or deaths. On postoperation days 10 and 20, Laploop showed a moderate degree of tissue reaction proved by a Sewell score of 57 and 48 respectively and on postoperation days 30 and 40, a mild to moderate degree of tissue reaction occurred with a S score of 36 and 33 respectively. In models using Vicryl, the S scores were 67 an 62 on postoperation days 10 and 20 respectively showing a moderate degree of tissue reaction and on postoperation days 30 and 40, it showed a mild to moderate degree of tissue reaction with a S score of 52 and 44 respectively which is similar to the results obtained by Laploop. CONCLUSION: Imported Vicryl and Laploop were both applicable in terms of biologic compatibility but Laploop was easier to apply, more cost effective compared to Vicryl but most of all, there were no complications such as a loosening of a knot or a knot being undone. Therefore it could be concluded that Laploop shows a promising future as a suture material in laparoscopic surgery.

Fine needle aspiration cytology of the salivary lesions was performed on 221 patients at Soonchunhyang University Hospital for 10 years. Of 221 aspirates, 6 aspirates(2.7%) were inadequate, 116 cases(52.5%) were non-neoplastic lesions, 76(34.4%) cases were benign neoplasms and 23 cases(10.4%) were malignant neoplasms. The cytologic diagnoses could be correlated with histologic findings in 58 cases. FNAC correctly discriminated between neoplastic and nonneoplastic lesions in fifty-seven lesions and failed in a case, and overall accuracy, sensitivity, and specificity were 98.3%, 98.0%, and 100.0%. FNAC correctly discriminated malignant neoplasms from benign neoplastic/non- neoplastic lesions in fifty-three cases and failed in five cases, and overall accuracy, sensitivity, and specificity were 91.3%, 72.7%, and 95.7%. Among three false negative cases, two mucoepidermoid carcinomas were misdiagnosed as mucocele and benign neoplasm, and an acinic cell carcinoma were misdiagnosed as Warthin's tumor. Two false positive cases were a Warthin's tumor misdiagnosed as squamous cell carcinoma and a pleomorphic adenoma misinterpretated as suggestive of malignancy. In conclusion, diagnostic accuracy of FNAC of salivary lesions is high, and the possibilities of low grade mucoepidermoid carcinoma and acinic cell carcinoma should be considered on hypocellular smears with mucoid or fluidy background.

OBJECTIVES: This study was conducted to compare the object relations and parenting behavior of the mothers of children with attention-deficit hyperactivity disorder (ADHD) with that of the mothers with normal children. METHODS: In this study, we studied 64 mothers of children who were diagnosed with ADHD and 90 mothers of normal children. The mothers completed the Bell Object Relations Inventory (BORI), the Parenting Behavior Inventory (PBI), the Parenting Stress Index (PSI) and the Parenting Sense of Competence (PSOC) scale. RESULTS: As compared with the mothers of normal children, the mothers of children with ADHD showed significantly different results for the parenting stress and parenting efficacy. For parenting behavior, the mothers of children with ADHD perceived their mothering as being more neglectful. On the other hand, the mothers of the normal control group perceived their mothering as being more affectionate and the fathers as being more reasonable and monitoring. CONCLUSION: This study suggests there is a significant difference of object relation between the mothers of children with ADHD and the mothers with normal children. The object relation pathology of the mothers of children with ADHD might contribute to impaired parenting behavior. The result of the present study indicate that inadequate grandparental rearing behavior affects the insecure object relation of their child (the mother), and a mother's insecure object relation affects their parental stress and parenting efficacy.
