BACKGROUND/OBJECTIVES: Coronavirus disease 2019 (COVID-19) cases were first reported in December 2019, in China, and an increasing number of cases have since been detected all over the world. The purpose of this study was to collect significant news media reports on food services during the COVID-19 crisis and identify public communication and significant concerns regarding COVID-19 for suggesting future directions for the food industry and services. SUBJECTS/METHODS: News articles pertaining to food services were extracted from the home pages of major news media websites such as BBC, CNN, and Fox News between March 2020 and February 2021. The retrieved data was sorted and analyzed using Python software. RESULTS: The results of text analytics were presented in the format of the topic label and category for individual topics. The food and health category presented the effects of the COVID-19 pandemic on food and health, such as an increase in delivery services. The policy category was indicative of a change in government policy. The lifestyle change category addressed topics such as an increase in social media usage. CONCLUSIONS This study is the first to analyze major news media (i.e., BBC, CNN, and Fox News) data related to food services in the context of the COVID-19 pandemic. Text analytics research on the food services domain revealed different categories such as food and health, policy, and lifestyle change. Therefore, this study contributes to the body of knowledge on food services research, through the use of text analytics to elicit findings from media sources.

PURPOSE: This study was performed to assess frequency, timings of occurrence, and predictors of radiologic lung damage (RLD) after forward-planned intensity-modulated radiotherapy (FIMRT) for whole breast irradiation. METHODS: We retrospectively reviewed medical records of 157 breast cancer patients and each of their serial chest computed tomography (CT) taken 4, 10, 16, and 22 months after completion of breast radiotherapy (RT). FIMRT was administered to whole breast only (n=152), or whole breast and supraclavicular regions (n=5). Dosimetric parameters, such as mean lung dose and lung volume receiving more than 10 to 50 Gy (V10-V50), and clinical parameters were analyzed in relation to radiologic lung damage. RESULTS: In total, 104 patients (66.2%) developed RLD after whole breast FIMRT. Among the cases of RLD, 84.7% were detected at 4 months, and 15.3% at 10 months after completion of RT. More patients of 47 or younger were found to have RLD at 10 months after RT than patients older than the age (11.7% vs. 2.9%, p=0.01). In univariate and multivariate analyses, age >47 and V40 >7.2% were significant predictors for higher risk of RLD. CONCLUSION: RLD were not infrequently detected in follow-up CT after whole breast FIMRT. More detected cases of RLD among younger patients are believed to have developed at later points after RT than those of older patients. Age and V40 were significant predictors for RLD after whole breast intensity-modulated radiotherapy.

We report here the short-term results of 3 cases of cloacal and bladder exstrophy that underwent complete primary exstrophy repair. One case was diagnosed as bladder exstrophy and the others were diagnosed as cloacal exstrophy. Complete primary exstrophy repair for all 3 cases was carried out within 24 hours after birth. There was no wound dehiscence within the follow-up period of 12 months. The complete primary exstrophy repair with positioning the bladder neck and urethra in the deep pelvic cavity achieves a satisfactory short-term result.

PURPOSE: The purpose of this study is to evaluate the costs and benefits of individual home visiting health care using secondary data and literature review. METHODS: The total number of subjects was 1,008,837. A specific program was classified into disease management, care of infant, child and women, or elderly care. The costs and effects of a program were identified from a societal perspective, and the effects were converted into monetary terms or benefits. The total cost was calculated in the way that medical expenses, travel costs and productivity losses were offset by the decrease in benefits and thus only the program budget was included in the total cost. RESULTS: The total program cost was 47.6 billion won per year and the total annual benefit was estimated at 435.6 billion won. The benefits of arthritis management were the biggest among disease management programs. The net benefit was 388.0 billion won per year and the benefit/cost ratio was 9.16. CONCLUSION: Home visiting health care was validated to be economically effective. It made a positive contribution to improving the health status of vulnerable populations and reducing medical expenses. These results suggest that home visiting care should be extended more broadly to vulnerable populations.

Dopamine is a catecholamine used in the treatment of circulatory shock of various etiologies. The usual dose range used is from 1 to 25 ug/kg/min. When used at higher doses, the prominent effect of dopamine on the vasculature is vasoconstriction induced by stimulation of alpha-adrenergic receptors. We report a case of dopamine gangrene. The gangrene developed on the injection site in the right dorsum of foot in a 43-year-old man during infusion of dopamine for treatment of septic shock. The gangrenous lesion healded after change of injection site to subclavian vein. The dosage of dopamine was not higher, we think that the gangrene developed due to the local vasoconstriction caused by dopamine leakage from the vessels.

PURPOSE: Laparoscopic pyeloplasty was developed as a minimally invasive alternative to an open procedure for the treatment of ureteropelvic junction (UPJ) obstruction. We present our experience with the first 30 consecutive cases of laparoscopic pyeloplasty performed at our institution. MATERIALS AND METHODS: We studied 30 patients with ureteropelvic junction obstructions who underwent laparoscopic pyeloplasty between March 2004 and March 2009. Of the 30 patients, 5 patients underwent robot-assisted laparoscopic pyeloplasty (RALP) since April 2008. Patients were divided into 4 groups according to operative procedure: group 1, early laparoscopic pyeloplasty-dismembered (E/LP-D, n=9); group 2, late laparoscopic pyeloplasty-dismembered (L/LP-D, n=9); group 3, laparoscopic pyeloplasty-Fenger's method (LP-F, n=7); and group 4, RALP (n=5). RESULTS: The mean age of the patients was 34.0+/-12.8 years (range, 17-61 years). A crossing vessel was present in 37.9% of cases. Mean follow-up was 30+/-14 months (range, 11-62 months). Mean operative time was 267.3+/-78.7 minutes (range, 154-460 minutes), and the average length of the postoperative hospital stay was 4.6+/-1.6 days (range, 3-10 days). There were no intraoperative complications or transfusion. The success rate was 73.3%. The success rates of E/LP-D, L/LP-D, LP-F, and RALP were 6/9 (66.7%), 7/9 (77.8%), 5/7 (71.4%), and 4/5 (80%), respectively, without significant difference (p>0.05). Operation time and length of hospital stay were shorter in the L/LP-D group than in the E/LP-D group. CONCLUSIONS: Laparoscopic pyeloplasty may be an alternative treatment for an ureteropelvic junction obstruction, but the technical complexity of the procedure has made it difficult for many surgeons to adopt. RALP is a technically feasible management option for UPJ obstruction.

OBJECTIVE: This study examined patients who visited the emergency department of a national medical center equipped with rabies vaccine and rabies immunoglobulin to confirm whether the treatment for rabies vaccination was appropriate in the emergency department. METHODS: This was a retrospective study that included 397 patients from January 1, 2014, to October 31, 2017. The patients finally diagnosed with animal bites according to the International Classification of Diseases, 10th revision code, at emergency department were collected. RESULTS: Most of the patients were 20–30 years old. Most of them were bitten by a dog, especially in the upper limb. Only 84% of patients who met the domestic rabies post-exposure prophylaxis (PEP) criteria were vaccinated. Patients who did not meet the criteria, approximately 22.3%, were also vaccinated. Complications after vaccination included clinical symptoms, such as headache, numbness, mild itching, and heating sensation. CONCLUSION: Rabies is a disease that can be prevented through PEP. Rabies PEP is relatively expensive and difficult to vaccinate easily, so it is desirable to subdivide the existing domestic rabies PEP guidelines into reality. Emergency physicians should know the proper rabies vaccination criteria and vaccinate patients only if necessary. This will help reduce medical resources and the complications of rabies vaccinations.

PURPOSE: To assess the prognostic factors for recurrence-free survival after salvage radiotherapy (RT). MATERIALS AND METHODS: Between 1990 and 2003, 20 patients underwent RT for biochemical failure after a radical prostatectomy (prostate-specific antigen; PSA>0.2ng/ml). The biochemical failure developed at a mean of 17.3 months (3-58) after the RP, and the mean PSA level at failure was 0.62ng/ml (0.4-1.0). All patients received curative radiation (mean dosage 64.5Gy); with a mean follow-up of 42.7 months after the RT. The pre-RT clinical and pathological parameters were evaluated to find prognostic factors affecting the biochemical recurrence-free survival (bRFS) after RT. RESULTS: The mean time to RT from biochemical failure was 5.1 months (1-21), with a mean PSA level at the commencement of RT of 1.39ng/ml (0.36-6.70). In 18 patients, the serum PSA declined to an undetectable level, at a mean of 4.9 months (1-12) after RT. Of these, 8 (44.4%) showed a biochemical relapse, at a mean of 19.3 months (1-38). The actuarial 1, 3 and 5-year bRFS were 75.0, 48.5 and 39.0%, respectively. The bRFS was significantly increased with an interval to RT after failure of within 3 months (p=0.002) and the PSA level at RT was below 0.7ng/ml (p=0.036). No other clinicopathological factors had a significant influence. CONCLUSIONS: Salvage RT for biochemical failure provides effective local tumor control, with a modest durable biochemical response. A more favorable outcome may be expected when the RT is instituted earlier, with a lower PSA level after failure.

PURPOSE: Gallbladder cancer had poor prognosis because it is usually detected at a late stage. Some GB polyps are diagnosed as cancerous on the postoperative pathology. Because of the significance of the early detection of the cancer, the relationship between GB polyp and cancer is important. METHODS: From January 1994 to May, 2004, 94 cases of GB polypoid lesions were identified and diagnosed after cholecystectomy was performed at the Korea University Medical Center Anam hospital. The pateints' age, gender, the symptoms and signs, the diagnostic tools, the operative methods and the histopathologic findings were investigated. RESULTS: For the 94 patients, the mean age was 50.3+/-13.1 years and there were 42 males (44.7%). 92 patients were evaluated by abdominal ultrasonography, and it had a sensitivity of 72.8%. On the histopathologic results, there were 76 cases of benign polyps and 18 cases of malignant polyps. The diameter of the malignant polyps was 17.3+/-8.5 mm and the diameter of the benign polyps was 6.4+/-3.0 mm, so the malignant polyps were larger than the benign polyps. The mean age of the malignant polyp group was 62.6+/-14.2 years and the mean age of the benign polyp group was 47.1+/-11.1. The patients of the malignant polyp group were older than the patients of the benign polyp group. 19 GB polyps were greater than 10 mm in diameter and among them, there were 15 cases of malignant polyps (78.94%). CONCLUSION: The size of the polyps and the patient's age could be risk factors for malignant polyps, and the malignant potential was high for the polyps that exceeded 10 mm and for a patient age that exceeded 60 years. Surgical treatment is recommended for these patients.

Unreduced small bowel intussusception requires operative treatment although the rate of spontaneous reduction is 60 to 70%. The aim of this study is to compare clinical characteristics and outcome between spontaneous reduction and operation group and to analyze factors related to decisions to treat small bowel intussusceptions. The records of 25 patients with small bowel intussusceptions treated in Seoul National University Children's Hospital from January 1999 to August 2009 were reviewed respectively. Spontaneous reduction group (n=12, 48%) had signs and symptoms of vomiting, abdominal pain, currant jelly stool, abdominal distension, fever, increased CRP but no rebound tenderness. One of them had been diagnosed with Henoch-Schonlein purpura and no one displayed pathologic leading point by image study. Operation group (n=13, 52%) consisted of patients who had primary surgery. Their signs and symptoms were similar to spontaneous reduction group. Seven of them had underlying diseases such as Crohn' disease, ALL, Lymphoma, Peutz-Jeghers syndrome (n=3), post-transplanted state of liver and 2 of them displayed Peutz-Jeghers polyp and Meckel's diverticulum as pathologic leading point by preoperative ultrasonography. Mean relieve interval (interval between onset of symptoms and reduction/operation) was 1.78 days in spontaneous reduction group and 2.25 days in operation group (p=0.341). Seven of operation group had manual reduction and 6 out of 7 received segmental resection of the small bowel. No one of them underwent manual reduction and all of them underwent segmental resection were found to have pathologic leading points [Peutz-Jeghers polyp (n=3), Meckel's diverticulum (n=2), lymphoma (n=1)] during operation. In conclusion, 48% of small bowel intussusceptions resolved spontaneously. Patients' symptoms and relieve intervals were not related to the operative decisions. We therefore recommend significant factors for determining treatment plan such as change of clinical symptoms, underlying disease or pathologic leading point by imaging.
