Baker's cyst is found as most frequent cystic mass around the knee occurring between medial head of gastrocnemius muscle and semimembranosus muscle. The proximal or posterolateral extension of the cyst had been rarely reported and the cyst into the surrounding muscular tissue extremely rare. Intramuscular Baker's cyst that we report was found between lateral head of gastrocnemius muscle and popliteus tendon, and then extended into the plantaris muscle. With review of the literature, we here report a very rare case of plantaris muscular extension of Baker's cyst.

PURPOSE: To evaluate retrospectively the survival outcome, patterns of failure, and complications in patients treated with postoperative chemoradiotherapy (CRT) in advanced gastric cancer. MATERIALS AND METHODS: Between January 2000 and December 2006, 80 patients with advanced gastric cancer who received postoperative concurrent CRT were included. Pathological staging was IB-II in 9%, IIIA in 38%, IIIB in 33%, and IV in 21%. Radiotherapy consisted of 45 Gy of radiation. Concurrent chemotherapy consisted of a continuous intravenous infusion of 5-fluorouracil and leucovorin on the first 4 days and last 3 days of radiotherapy. RESULTS: The median follow-up period was 48 months (range, 3 to 83 months). The 5-year overall survival, disease-free survival, and locoregional recurrence-free survivals were 62%, 59%, and 80%, respectively. In the multivariate analysis, significant factors for disease-free survival were T stage (hazard ratio [HR], 0.278; p = 0.038), lymph node dissection extent (HR, 0.201; p = 0.002), and maintenance oral chemotherapy (HR, 2.964; p = 0.004). Locoregional recurrence and distant metastasis occurred in 5 (6%) and 18 (23%) patients, respectively. Mixed failure occurred in 10 (16%) patients. Grade 3 leukopenia and thrombocytopenia were observed in 4 (5%) and one (1%) patient, respectively. Grade 3 nausea and vomiting developed in 8 (10%) patients. Intestinal obstruction developed in one (1%). CONCLUSION: The survival outcome of the postoperative CRT in advanced gastric cancer was similar to those reported previously. Our postoperative CRT regimen seems to be a safe and effective method, reducing locoregional failure without severe treatment toxicity in advanced gastric cancer patients.

Malignant transformation of heterotopic pancreas is extremely rare. We report a case of ductal adenocarcinoma arising from heterotopic pancreas in the stomach of a 64-year-old man. Preoperative CT scans showed the lesion as a submucosal mass along the greater curvature of the pyloric antrum and protruding into the pyloric canal. After gastric surgery, the resected tumor was histopathologically diagnosed as a ductal adenocarcinoma arising from heterotopic pancreas with cystic dilatation of aberrant pancreatic duct.

PURPOSE: Lower urinary tract dysfunction is the most common complication after radical pelvic surgery. The aims of this study were to assess the effect of radical hysterectomy (RH) on the storage function of the lower urinary tract and to evaluate the impact of radiation therapy (RT) on postoperative urodynamic parameters. METHODS: This was a retrospective review of preoperative and postoperative urodynamic variables, which were prospectively collected. All women from 2006 to 2008, who underwent RH for uterine cervical cancer with a stage of 1A to 2B with or without adjuvant RT were enrolled. All patients were divided into two groups: group 1, without RT, and group 2, with adjuvant RT. Urodynamic studies were performed before, 10 days after, and 6 months after RH. RESULTS: A total of 42 patients with a mean (+/-standard error) age of 51.9 (+/-12.3) years were analyzed. There were no significant differences in age, body mass index or clinical stage between the two groups. On the 10th postoperative day, all parameters were decreased except postvoid residual volume. In comparison with group 2 (n=14), group 1 (n=28) showed a significant increase in bladder compliance. At 6 months postoperatively, bladder compliance in group 1 had increased four times or more compared with that on postoperative 10 days. However, it had increased only 2.5 times in group 2 at the same time point (P<0.001). CONCLUSIONS: The results of our study suggest that adjuvant RT after RH might result in a deterioration of bladder compliance. It is highly suggested that practitioners pay attention to low bladder compliance, especially in patients who have adjuvant RT after RH.

Extra-adrenal abdominal paragangliomas are rare. Most arise from the organs of Zuckerkandl, involve large concentrations of paraganglionic tissue, and are located in the para-aortic space along the sympathetic chain. Published reports have, however, described normal paraganglionic tissue at the root of the mesentery which serves as the superior limit of the organs of Zuckerkandl, and mesenteric paraganglioma is very rare. We report a case of paraganglioma with cystic degeneration arising from the mesentery.

OBJECTIVES:
This study investigated the reporting rates of adverse events following immunization (AEFIs) to the spontaneous reporting system (SRS) and its predictors among individuals with AEFIs after coronavirus disease 2019 (COVID-19) vaccination.
METHODS:
A cross-sectional, web-based survey was conducted from December 2, 2021 to December 20, 2021, recruiting participants >14 days after completion of a primary COVID-19 vaccination series. Reporting rates were calculated by dividing the number of participants who reported AEFIs to the SRS by the total number of participants who experienced AEFIs. We estimated adjusted odds ratios (aORs) using multivariate logistic regression to determine factors associated with spontaneous AEFIs reporting.
RESULTS:
Among 2,993 participants, 90.9% and 88.7% experienced AEFIs after the first and second vaccine doses, respectively (reporting rates, 11.6 and 12.7%). Furthermore, 3.3% and 4.2% suffered moderate to severe AEFIs, respectively (reporting rates, 50.5 and 50.0%). Spontaneous reporting was more prevalent in female (aOR, 1.54; 95% confidence interval [CI], 1.31 to 1.81); those with moderate to severe AEFIs (aOR, 5.47; 95% CI, 4.45 to 6.73), comorbidities (aOR, 1.31; 95% CI, 1.09 to 1.57), a history of severe allergic reactions (aOR, 2.02; 95% CI, 1.47 to 2.77); and those who had received mRNA-1273 (aOR, 1.25; 95% CI, 1.05 to 1.49) or ChAdOx1 (aOR, 1.62; 95% CI, 1.15 to 2.30) vaccines versus BNT162b2. Reporting was less likely in older individuals (aOR, 0.98; 95% CI, 0.98 to 0.99 per 1-year age increment).
CONCLUSIONS
Spontaneous reporting of AEFIs after COVID-19 vaccination was associated with younger age, female sex, moderate to severe AEFIs, comorbidities, history of allergic reactions, and vaccine type. AEFIs under-reporting should be considered when delivering information to the community and in public health decision-making.

Background:
Although coronavirus disease 2019 (COVID-19) vaccines have been distributed worldwide under emergency use authorization, the real-world safety profiles of mRNA vaccines still need to be clearly defined. We aimed to identify the overall incidence and factors associated with adverse events (AEs) following mRNA COVID-19 vaccination.
Methods:
We conducted web-based survey from December 2 to 10 in 2021 with a 2,849 nationwide sampled panel. Study participants were individuals who had elapsed at least twoweeks after completing two dosing schedules of COVID-19 vaccination aged between 18–49 years. We weighted the participants to represent the Korean population. The outcome was the overall incidence of AEs following mRNA COVID-19 vaccination and associated factors.We estimated the weighted odds ratios (ORs) using multivariable logistic regression models to identify the factors associated with AEs.
Results:
Of the 2,849 participants (median [interquartile range] age, 35 [27–42] years; 51.6% male), 90.8% (n = 2,582) for the first dose and 88.7% (n = 2,849) for the second dose reported AEs, and 3.3% and 4.3% reported severe AEs, respectively. Occurrence of AEs was more prevalent in mRNA-1273 (OR, 2.06; 95% confidence interval [CI], 1.59–2.67 vs. BNT162b2), female sex (1.88; 1.52–2.32), and those with dermatologic diseases (2.51; 1.32–4.77). History of serious allergic reactions (1.96; 1.06–3.64) and anticoagulant medication use (4.72; 1.92–11.6) were associated with severe AEs.
Conclusion
Approximately 90% of participants reported AEs following mRNA COVID-19 vaccination. Substantial factors, including vaccine type (mRNA-1273), female sex, and dermatologic diseases were associated with AEs. Our findings could aid policymakers in establishing vaccination strategies tailored to those potentially susceptible to AEs.

Positron Emission Tomography (PET) is a new imaging method employing radionuclide and tomography technique. In breast cancer PET has high sensitivity in detecting primary tumor and axillary node metastasis. From 1995 June to 1996 November, 27 patients had undergone breast operations following PET under impression of breast cancer in Seoul National University Hospital (SNUH). Whole body PET images were obtained beginning 60 minutes after infection of 370 MBq (10 mCi) F-18 FDG (fluorodeoxy glucose). Regional scans were also obtained with transmission images. We compared PET results with those of physical examination and mammography. All cases were histologically confirmed. For primary tumor mass, diagnostic accuracy of PET was excellent (97%) compared with the physical examination (78%) and mammography (67%). For axillary lymph node metastasis, PET had an outstanding detection accuracy (96%), compared with the physical examination and mammography (74%, 60%, respectively). And whole body PET scan made it possible to see the all metastatic lesions at a glance in cases of metastatic or recurred breast cancer. There was likely correlation between Standard Uptake Value (SUV) and the number of axillary lymph node metastasis, but in this study, statistical significance was not proven because of small number of cases. PET also could detect breast cancer in paraffin augmented breast. We concluded that PET is very sensitive and accurate diagnostic tool for breast cancer and SUV, after more studies, could be used as an important prognostic factor.

PURPOSE: The aim of this study was to evaluate the short- term outcome of a pylorus-preserving proximal gastrectomy by comparing it with a jejunal interposition after a total gastrectomy in proximal gastric adenocarcinoma. MATENRIALS AND METHODS: For 22 patients (12 men and 10 women) who underwent a pylorus-preserving proximal gastrectomy, several clinical parameters were obtained from the medical records retrospectively. In this study, the data were collected between September 1993 and December 1999 at Chungnam National University Hospital, and the results were compared with those of 25 patients (17 men and 8 women) who underwent an isoperistaltic simple jejunal interposition. RESULTS: The average operative time in the pylorus-preserving proximal gastrectomy group (220 minutes) was shorter than that in the jejunal interposition group (243 minutes) (P<0.05). The hemoglobin and hematocrit levels were significantly higher in the pylorus-preserving proximal gastrectomy group at 2 years after the operation. The body weight ratio (postoperative body weight/preoparative body weight) in patients who had a pylorus-preserving proximal gastrectomy was significantly higher than that in patients with a jejunal interposition at 2 years after the operation. The jejunal interposition procedure had better outcomes in anastomotic site stricture, duration of hospital stay, and number of removed lymph nodes (P<0.05). CONCLUSION: We think that from the viewpoint of quality of life, a pylorus-preserving proximal gastrectomy, as well as a jejunal interposition, is a useful reconstruction method for early adenocarcinomas of the proximal stomach. However, stricture of the esophagogastrostomy site in the pylorus- preserving proximal gastrectomy is a common problem to be solved in the future.

BACKGROUND: Milrinone increases intracellular adenosine 3',5'-cyclic monophosphate concentration and enhances vascular relaxation. Nuclear factor-kappa B (NF-kB) plays a key role in inflammatory responses during ischemia-reperfusion (I/R) injury. We aimed to investigate the effect of milrinone on the inflammatory responses and NF-kB activation in renal I/R injury in mice. METHODS: Thirty C57BL/6 mice were allocated into 3 groups. In group S (n = 10), only right nephrectomy was done. In group C (n = 10), the left kidney was subjected to 30 min of ischemia after right nephrectomy. In group M (n = 10), milrinone (5 microg/kg) was administered before ischemia. After 24 hours of reperfusion, the serum creatinine was measured, kidney samples were obtained for histology, and expressions of NF-kB and proinflammatory cytokines were analyzed. RESULTS: In group C, the serum creatinine concentration was markedly elevated, compared with group S. Creatinine concentration in group M was also elevated, but it was significantly lower than that in group C. Histologic evidence of renal damage was severe in group C, but it was improved in group M. In groups C and M, expression of NF-kB, tumor necrosis factor-alpha (TNF-alpha), intercellular adhesion molecule-1 (ICAM-1), monocyte chemoattractant protein-1 (MCP-1) and macrophage inflammatory protein-2 (MIP-2) mRNA increased significantly compared with group S (P < 0.05). But group M showed a lower expression of NF-kB, TNF-alpha, ICAM-1, MCP-1 and MIP-2 mRNA than group C (P < 0.05). CONCLUSIONS: Milrinone treatment attenuates the renal inflammatory response and activation of NF-kB, resulting in improvement of renal function and tissue injury.
