Purpose: The purpose of this study was to identify the influence of the nurse’s character on care and the sense of coherence (SOC) on the professional quality of life among oncology nurses. Methods: Data were collected from June 2 to July 1, 2020. The participants were 185 oncology nurses caring for cancer patients. Data were analyzed using independent t-test, one-way ANOVA, Scheffé test, Pearson correlation coefficient, and hierarchical multiple regression with the SPSS/WIN 22.0 program. Nurse’s Character Scale for Care in Clinical Settings (NCS_C) and SOC, Professional Quality Of Life (ProQOL), which is conceptualized with three sub-dimensions (compassion satisfaction, compassion fatigue, burnout, and secondary traumatic stress), along with demographic and work-related variables were measured. Results: The compassion satisfaction and burnout results had a significant correlation with the nurse’ s character for care and SOC. In multiple regression analysis, the meaningfulness of sub-dimension SOC (β=.58) accounted for 67.8% of compassion satisfaction and the meaningfulness of sub-dimension SOC (β=-.37) accounted for 55.4% of burnout. Conclusion Meaningfulness of sub-dimension SOC was an important factor that could be used to improve the professional quality of life among oncology nurses. Therefore, it is necessary to develop and make available programs for oncology nurses to improve compassion satisfaction, and methods to decrease burnout needs to be developed.

Background/Aims: The aim of this in vivo animal study was to evaluate the effectiveness and safety of dedicated cold snare (DCS) compared with those of traditional snare (TS) for cold snare polypectomy (CSP). Methods: A total of 36 diminutive (5 mm) and 36 small (9 mm) pseudolesions were made by electrocoagulation in the colons of mini-pigs. Results: For the diminutive lesions, there were no significant differences in technical success rate, procedure time, or complete resection rate between the DCS and TS groups; the rate of uneven resection margin in the DCS group was significantly lower than that of the TS group. For small lesions, technical success rate and complete resection rate were significantly higher in the DCS group than in the TS group (100% [18/18] vs. 55.6% [10/18], p=0.003; 94.4% [17/18] vs. 40% [4/10], p=0.006). In addition, the procedure duration was significantly shorter, and the rate of uneven resection margin was significantly lower in the DCS group (28.5 sec vs. 66.0 sec, p=0.006; 11.1% [2/18] vs. 100% [10/10], p<0.001). Two cases of perforation occurred in the DCS group. Multivariate analysis revealed that DCS use was independently associated with complete resection. Conclusions DCS is superior to TS in terms of technical success, complete resection, and reducing the duration of the procedure for CSP of small polyps.

BACKGROUND/AIMS: Presence of enhanced mural nodules, which can be visualized using computed tomography (CT), is one of high-risk stigmata in branch-duct intraductal papillary mucinous neoplasms (BD-IPMNs). Conversely, the absence of enhanced mural nodules on preoperative imaging does not exclude malignant risk. The present study aimed to investigate other morphological features as predictors of malignancy in “pure” BD-IPMNs without enhanced mural nodules on CT. METHODS: This retrospective study included 180 patients with surgically confirmed “pure” BD-IPMNs of the pancreas and no enhanced mural nodules on preoperative CT. The study was conducted at 15 tertiary referral centers throughout South Korea. Univariate and multivariate analyses were used to identify significant predictors of malignancy. RESULTS: BD-IPMNs with low-grade (n=84) or moderate-grade (n=76) dysplasia were classified as benign; those with high-grade dysplasia (n=8) or invasive carcinoma (n=12) were classified as malignant. The multivariate analysis revealed that cyst size ≥30 mm (odds ratio, 8.6; p=0.001) and main pancreatic duct diameter ≥5 mm (odds ratio, 4.1; p=0.01) were independent risk factors for malignancy in “pure” BD-IPMNs without enhanced mural nodules on CT. Endoscopic ultrasound detected enhanced mural nodules (6/82) that had been missed on CT, and two IPMNs with enhanced mural nodules were malignant. CONCLUSIONS: In patients with “pure” BD-IPMNs who have no enhanced mural nodules on CT, cyst size ≥30 mm and main pancreatic duct diameter ≥5 mm may be associated with malignancy.

A 24-year-old man was admitted due to an incidentally detected mass in his left testis, which showed radiopaque calcification on plain X-ray film. Left orchiectomy was performed, and the resected testis contained a well-demarcated, hard mass measuring 1.1 cm. Histological analysis revealed that the tumor was composed of neoplastic cells, fibrotic stroma, and laminated or irregularly shaped calcific bodies. The individual cells had abundant eosinophilic or clear cytoplasm with round nuclei, each of which contained one or two conspicuous nucleoli. They were arranged in cords, trabeculae, clusters, and diffuse sheets. There were several foci of intra-tubular growth patterns, with thickening of the basal lamina. Immunohistochemically, the neoplastic cells were positive for S-100 protein and vimentin, focally positive for inhibin alpha, and negative for cytokeratin, CD10, and Melan-A. In addition to reporting this rare case, we also review the relevant literature regarding large cell calcifying Sertoli cell tumors.

BACKGROUND/AIMS: Narrow band imaging (NBI) is a new technique that is expected to improve the detection rate of colorectal polyps, but results have been inconsistent. The aim of this study was to compare the polyp miss rate and the characteristics of missed colorectal polyps using white light (WL) and NBI. METHODS: 62 patients were randomized into two groups. In the first group (NBI first, NBIF), a colonoscopic examination of each segment (cecum-ascending, transverse, descending, and rectosigmoid colons) was performed first with NBI followed by a re-examination of the same segment using WL. An opposite sequence was applied for the other group (white light first, WLF). RESULTS: 67 polyps were found in the first examination, and 31 polyps were found on the re-examination, resulting in a polyp miss rate of 31.6%. The polyp miss rate was 39% for WLF and 23% for NBIF (p>0.05). Seventy-four small polyps (<5 mm) were found, and miss rates for NBIF and WLF were 20% and 46%, respectively (p=0.01). The polyp miss rate at the rectosigmoid was 11% for NBIF and 54% for WLF (p=0.01). CONCLUSIONS: The polyp miss rate was not significantly different between NBI or WL when a colonoscopy was performed. NBI resulted in a lower polyp miss rate for small (<5 mm) and rectosigmoid polyps than WL.

Cyclic vomiting syndrome (CVS) is a disorder characterized by recurrent episodes of incapacitating nausea and vomiting interspersed with symptom free periods. Common triggers of cyclic vomiting include noxious stress, excitement, fatigue and menstrual period. Here, we report a case of cyclic vomiting syndrome in adult patient characterized by stereotypical vomiting attack, occurring in every menstruation period. Recurrent vomiting episodes began 6 years ago and we treated this patient with subcutaneous injection of goserelin, a gonadotropin-releasing hormone analogue (GnRHa) and oral estrogen. After 4 months of therapy, she was symptom free for the following 5 years, even with the resumed normal menstruation. Recurrence of vom - iting attack with same pattern occurred 1 month before readmission. Treatment with intravenous lorazepam aborted vomiting, but could not prevent recurrences of vomiting and epigastric pain. We treated the patient with GnRHa and oral estradiol again which effectively prevented recurrence of the symptoms.

BACKGROUND: Cystic neoplasms of the pancreas are being recognized with increased frequency. In 1993, a report on 123 cases of cystic neoplasms of the pancreas diagnosed over a period of 32 years was published in Korea. Many changes on the concept of cystic neoplasms of the pancreas have been made, including classification and diagnostic criteria. The present study was conducted wherein a new survey on cystic neoplasms of the pancreas in Korea. METHODS: Cystic neoplasms of the pancreas diagnosed over a period of 12 years, from 1993 to 2004 in 25 university hospitals throughout Korea were collected. They were classified according to the World Health Organization classification of cystic neoplasms of the pancreas. RESULTS: A total of 1264 cases of cystic neoplasms of the pancreas were diagnosed. The diagnoses and frequencies are as follows: intraductal papillary mucinous neoplasm, 499 (39.5%); mucinous cystic neoplasm, 318 (25.2%); serous cystic neoplasm, 232 (18.4%); solid pseudopapillary neoplasm, 192 (15.2%); cystic endocrine neoplasm, 11 (0.8%); lymphoepithelial cyst, 8 (0.6%); acinar cell neoplasm, 3 (0.2%); mature teratoma, 1 (0.1%). Increase in the annual number of diagnoses was evident. In intraductal papillary mucinous neoplasm and mucinous cystic neoplasm, a significant increase in mean age was seen in patients with malignant neoplasms. CONCLUSIONS: Cystic neoplasms of the pancreas are diagnosed with increasing frequency in Korea, the most common being intraductal papillary mucinous neoplasm of the pancreas. In intraductal papillary mucinous neoplasm and mucinous cystic neoplasm, the grade of dysplasia increased with mean age, suggesting an adenoma-carcinoma sequence.

There are diverse ring-like narrowings in the lower esophagus: mucosal ring, muscular ring, ring-like annular peptic stricture. Esophageal muscular ring is extremely rare and generally asymptomatic. It occurs at the proximal border of the esophageal vestibule that corresponds to the upper end of the lower esophageal sphincter. We experienced a case of lower esophageal muscular ring with a symptom of intermittent mild dysphagia for 40 years and report the findings with a review of the literature.
