This study was done to investigate satisfaction of fifth-grade(n=264) and sixth-grade(n=117) students from school foodservice in five elementary schools in Won-ju. On a scale of 1 to 5, with 1 being very poor and 5 being very good, overall satisfaction from school foodservice was found to be 3.21+/-0.98('so-so~satisfaction'). The highest satisfactory factor was neatness of foodservice staffs(3.79+/-1.00), while the lowest satisfactory factor was the students' overall opinions of school foodservice(3.03+/-1.06). The biggest unsatisfactory factor was found to be 'bland food'. 'Enhancement of taste'(49.08%) caused the most complaints against school foodservice. Soup was identified as the type of food most likely to be left over, and there was some significant difference between fifth-graders and sixth-graders. The reason cited most often for leftovers was unfavorable menus(33.42%). Students were more likely to try foods which were unfamiliar to them and also foods they previously disliked as a result of using school foodservice(28.87%). Also significant, when the meal director was present during the meal service, satisfaction was markedly higher than when the director was not present.

The authors analyzed 38 consecutive cases with an occipital arteriovenous malformation(AVM) in regard to visual field defect. The incidence of occipital AVM was 10.4% among 367 patients with a cerebral AVM treated between 1975 and 1994 in our institute. Bleeding rate of occipital AVM in this series was 86.8%(EE cases) and it was significantly higher than that of AVM in other locations. Of 38cases, 15 patients(39.5%) had a visual field defect on admission and all of them were accompanied by intracerebral hematomas caused by the rupture of AVMs. The presence of visual field defect did not correlate with angioarchitecture in reference to pattern of nidus, feeding artery, and draining vein. Of 15 patients with visual field defect. 10 patients showed homonymous hemianopsia and five patients, homonymous quadrantanopsia. The size and location of intracerebral hematoma correlated well with hemispheric approach : 11, parietooccipital approach : 10, with six preoperative embolization and 1 postoperative gamma knife surgery. Fifteen patients underwent gamma knife surgery with five preoperative embolization. One patient underwent embolization only. The results of treatment were as follows : There were no mortality and morbidity except for visual field defect. We confirmed complete resection or obliteration of malformed vessels in 25 patients and reduction of the nidus size in eight patients. Five patients were not followed. After gamma knife surgery, two patients showed rebleeding during the follow up period. Among 23 patients who had no visual field defect before treatment, three patients showed visual field defect after treatment(one after microsurgical resection using occipital interhemispheric approach, two after preoperative embolization). In 15 patients with visual field defect before treatment, four patients showed improvement in their visual field defect after treatment(three after microsurgical resection using occipital interhemispheric approach, one after gamma knife surgery). The parietooccipital approach did not change the status of visual field in any of the ten parients. In occipital AVM, visual field defect was the most srious morbidity. Ruptured occipital AVM had a higher incidence of hemorrhage causing a visual field defect and had a higher indication of direct surgical approach than AVM of other location. In planning surgery of occipital AVM, one has to count microsurgical anatomy based on the visual pathway as well as clinical findings such as the angioarchitecture, location of intracerebral hematoma, and preopeative visual field.

BACKGROUND: Recent studies suggest the hypothesis that blockade of nociceptive input with local anesthetics before surgery can decrease pain beyond the immediate postoperative period. The purpose of this study was to determine if the preincisional infiltration with local anesthetics affected postoperative pain relief. METHOD: Among 30 patients having tonsillectomy, 15 patients(group 1) given peritonsillar infiltration using lidocaine with epinephrine(1 : 200,000) were compared with 15 patients(group 2)given peritonsillar infiltration using saline with epinephrine(1 : 200,000). Following general anesthesia with a mixture of O2-N2O(50%) and enflurane(1-2vol.%), peritonsillar infiltration were performed 5 minutes before surgery. Constant incisional pain and pain on swallowing were assessed using a visual analogue scale at 4 hour, 1, 2, 3 and 4 days postoperatively. The time to emergence and behaviour of patient at 0.5, 1 and 4 hour were recorded postoperatively. RESULT: Preincisional infiltration with lidocaine resulted in a significant decrease in postoperative pain during 4 days after surgery and smoother emergence. CONCLUSION: There were significant difference in pain scores between lidocaine group and saline group during 4 days after surgery. Preincisional lidocaine infiltration seemed to have analgesic activity beyond the residual anesthetic period. The results of this study support the theory of pre-emptive analgesia.

Duplications of the stomach account for only 3.8% of gastrointestinal duplication, mainly discovered during first year of life. Etiopathogenesis is unknown. The most widely accepted theory is recannalization with fusion of longitudinal epithelial fold. The most frequent presented symptoms and signs include gastric outlet obstruction with vomiting, and palpable mass in the epigatric area. An upper gatrointestinal series usually reveals evidence of extrinsic mass effect of intramural lesion. An abdominal ultrasonographic finding is cystic mass lesion with double layer. Histologically, the wall of intramural cyst is composed of orderly layers of alimentary mucosa, submucosa, and muscle fibers. Recommended management is complete excision & simple closure of duplication without violation of the gastric lumen. In this case, 3-day old male newborn suffered from symptoms of gastric outlet obstruction, multiple gastric duplication cysts were found in pyloric canal and greater curvature. The cystic wall was composed with typical 3 layers of gastric mucosa, submucosa, and muscle fibers. The cystic wall was composed with typical 3 layers of gastric mucosa, submucosa, and muscle fibers. Surgical excision was successfully done.

Although varying types of cystic lesion, true to false, in the spinal cord have been described, spinal enterogenous cyst is a rare condition. It is considered as a result of congenital remnant of primitive foregut. The authors experienced a case of a spinal enterogenous cyst in the intradural space along the fouth, fifth and sixth cervical spine, occurred in a twenty-seven years old male patient. The cyst was composed of hyalinized fibrous wall with single layered lining epithelium, such as simple non-ciliated cuboidal epithelium or ciliated tall columnar epithelium with focal mucinous columnar epithelium.

BACKGROUND: The p73 is a recently identified homologue of the tumor suppressor gene, p53, and it has been found to induce apoptosis and inhibit cell proliferation. However, its role in the development of tumors is unclear. This study examined the expression of p73 in patients with non-small cell lung carcinomas (NSCLCs) to determine its clinical significance and association with the expressions of p53, pRb, and mdm2. METHODS: A total of 183 NSCLCs were analyzed immunohistochemically using a tissue microarray. RESULTS: The p73 protein was expressed in the cell nuclei in 156 (85.2%) out of the 183 cases. There was no correlation between the p73 expression and the clinicopathological variables. However, there was a correlation between the p73 expression and the mdm2 and pRb expressions. Multivariate Cox survival analysis identified tumor size and lymph node metastasis to be independent prognostic factors, but the p73 expression was not found to be associated with the patients' survival. CONCLUSIONS: p73 is commonly expressed in NSCLC and it might, in conjunction with pRb and mdm2, be involved in the development of these tumors.

Background: Most previous studies have evaluated flexion strength to assess recovery after arthroscopic rotator cuff (RC) repair.However, limited data are available regarding peak torque at the initial angle (iPT) because most studies have measured flexion strength for peak torque (PT), particularly in small- and medium-sized supraspinatus tears. The purpose of this study was to compare conventional PT and iPT to evaluate supraspinatus muscle strength after arthroscopic RC repair in patients with small- and medium-sized supraspinatus tears. Methods: Isokinetic muscle performance testing was performed in 42 patients with small tears and in 47 patients with medium-sized tears. PT and iPT were evaluated before and 1 year after surgery and were recorded at an angular velocity of 60°/sec and 180°/sec with an isokinetic test. Results: PT and iPT were significantly lower in the involved-side shoulders than in the uninvolved-side shoulders (PT: small tear, p < 0.001; medium tear, p < 0.001; iPT: small tear, p < 0.001; medium tear, p < 0.001) in both groups, preoperatively. However, postoperatively, in the involved-side shoulders, PTs were not different in both small- and medium-sized tears (all p > 0.05), but iPTs were significantly lower in the involved-side shoulders (small tear, p < 0.001; medium tear, p < 0.001). iPT was significantly lower in the involved side shoulders in the medium-sized tear group than in the small-sized tear group before and after surgery (p < 0.05). In the smalland medium-sized tear groups, tear size was significantly correlated with preoperative iPT in the involved-side shoulders (small tear: r = –0.304, p = 0.046; medium tear: r = –0.323, p= 0.027). However, pain visual analog scale was significantly correlated with preoperative (small tear: r = –0.455,p = 0.002; medium tear: r = –0.286, p = 0.044) and postoperative (small tear: r = –0.430, p = 0.005; medium tear: r = –0.354, p = 0.021) iPT in the involved-side shoulders. Furthermore, fatty infiltration grade of the supraspinatus muscle and global fatty degeneration index were not associated with preoperative and postoperative PT and iPT in each group (all p > 0.05). Conclusions iPT is as important as conventional PT in isokinetic testing to assess supraspinatus muscle strength before and after RC repair.

Background: Coronavirus disease 2019 (COVID-19) vaccination is necessary to reach herd immunity and essential for mitigating the spread of the pandemic. In May 2021, the US FDA and the EU have expanded the emergency use authorization for a COVID-19 vaccine to children aged 12 to 15. The aim of this study was to investigate parental acceptability of COVID-19 vaccination for their children, factors affecting their acceptability, and children's perceptions of COVID-19 vaccines in Republic of Korea. Methods: We conducted a questionnaire survey at two tertiary hospitals from May 25, 2021 to June 3, 2021. Subjects were parents having children under 18 years and children aged 10–18 years. Results: Two hundred twenty-six parents and 117 children aged 10–18 years were included in the final analysis. Overall, 76.5% and 64.2% of parents intended to get vaccinated against COVID-19 and intended to have their children vaccinated, respectively. However, only 49.6% of children responded that they would get COVID-19 vaccination. In the multivariate analysis, high confidence in the safety of COVID-19 vaccines (adjusted odds ratio [AOR], 4.87; 95% confidence interval [CI], 1.32–24.12), parents' willingness to vaccinate themselves (AOR, 19.42; 95% CI, 6.85–64.00), and awareness of the need to vaccinate children against COVID-19 (AOR, 13.15; 95% CI, 4.77–41.27) were associated with positive factors intention to vaccinate their children. Conclusion This study provides insight into how parents think about the COVID-19 vaccine for their children in South Korea. Our findings could be referenced in establishing a policy for childhood COVID-19 vaccination in the future.
