Necrotizing fasciitis is an invasive soft tissue infection that progresses rapidly. It rarely occurs in the craniocervical area but when it does, it can be fatal; an early diagnosis and treatment would be thus important. Patients with necrotizing fasciitis are treated with intravenous antibiotics after wide debridement of necrotic tissues and daily dressing with antibiotic solution. Since daily dressing is thought to be a bothering procedure to both patients and medical doctors, we applied negative pressure wound therapy on the necrotizing fasciitis wound after operation. Negative pressure wound therapy has been used broadly in the departments of plastic surgery, orthopedic surgery and urology but rarely in the department of otorhinolaryngology. After applying the negative pressure wound therapy, the wound was successfully healed. We hereby introduce the benefits of negative pressure treatment on necrotizing fasciitis patients.

Inflammatory myofibroblastic tumors (IMTs) are rare. They are characterized by myofibroblastic spindle cell proliferation with a varying degree of inflammatory cell infiltration. IMT can occur in any anatomic location but has been reported in the lung, mesentery, and omentum, mainly in children or young adults. It rarely occurs in the pancreas and is often difficult to distinguish from other tumors, including some malignant ones. Therefore, it can be challenging to make a radiological diagnosis of IMT. Here, we present a case of IMT that occurred in the pancreas head of a middle-aged female. The patient’s ultrasonography, computed tomography, and magnetic resonance imaging findings are presented along with a review of the literature.

Thymic adenocarcinoma is extremely rare. Although its histologic features have been occasionally reported, a lack of description of the cytologic features has hampered the prompt and accurate diagnosis of this condition. Herein, we describe the cytologic findings and histology of four aspiration cytology specimens of thymic adenocarcinoma. The specimens were obtained from primary tumors, metastatic lymph nodes, and pericardial effusions. All four specimens showed three-dimensional glandular clusters with a loss of polarity and nuclear overlapping. One specimen had extensive extracellular mucinous material. Three specimens contained tumor cells with intracytoplasmic vacuoles. While the specimen with extracellular mucin showed relatively mild cytologic atypia, other specimens exhibited more atypical cytologic changes: irregular nuclear membranes, a coarse chromatin pattern, and prominent nucleoli. The cytologic features were correlated with the histologic features in each case of enteric type thymic adenocarcinoma. The differential diagnosis included other thymic carcinomas, yolk sac tumors, and metastatic adenocarcinoma from the lung or colorectum.

BACKGROUND: Primary splenic vascular lesions include the tumor and the inflammatory condition. A primary splenic vascular tumor is rare but is the most common tumor of the benign primary splenic tumors. METHODS: We describe the clinicopathological, radiological, and immunophenotypical findings of 40 cases of primary vascular lesions identified at our hospital from 1996 to 2009. RESULTS: The patients included 18 men and 22 women, aged 12 to 74 years, with a mean of 43.3-years and median of 40-years. They comprised 14 hemangiomas (35%), 13 lymphangiomas (32.5%), three hamartomas (7.5%), three littoral cell angiomas (7.5%), three sclerosing angiomatoid nodular transformations (SANT, 7.5%) and four angiosarcomas (10%). The majority of the patients (65%) were asymptomatic. Some of the patients (32.5%) complained of abdominal pain, and 2.5% of the patients presented with fever. Metastases were identified in 75% of the patients with an angiosarcoma at the initial work-up. One angiosarcoma patient died of the disease despite adjuvant chemoradiotherapy. The radiological findings for hamartoma, littoral cell angioma, and SANT were nonspecific. Microscopically, six types of vascular lesions showed classic morphological and immunophenotypical features of their type. CONCLUSIONS: One should be aware of rare splenic vascular lesions when radiological findings are nonspecific. Histomorphological and immunophenotypical features are helpful for the differential diagnosis.

BACKGROUND AND OBJECTIVES: Diagnosis of thyroid disease requiring surgery and subsequent thyroidectomy may affect patients' emotion and quality of life. The purpose of this study is to evaluate the patients' understanding and concern about the disease and recovery rate after thyroidectomy, and therefore to enhance the satisfaction of hospitalization. SUBJECTS AND METHOD: MethodZZSeventy-seven patients undergoing thyroidectomy in a tertiary hospital from April 2009 to October 2009 were enrolled. Questionnaires were filled out on the admission day, discharge day, and 2 weeks after operation. Questionnaires consisted questions regarding the understanding of the disease, details of concern, recovery rate after surgery, and satisfaction on hospitalization duration. Retrospective chart review was also performed. RESULTS: Many patients (42.9%) acquired their knowledge of thyroid cancer through the internet. The possibility of voice change was the major concern before surgery (46.8%), whereas the major postoperative concern was adjuvant therapy (37.7%). The patient group with higher understanding of the disease showed higher recovery rate than the others at the time of discharge (mean postdischarge surgical recovery 67.4% vs. 55.3%, p=0.01). The patient group with lower understanding wanted longer hospitalization than the other group at discharge (p<0.001). CONCLUSION: Patient education about the thyroid disease may reduce patients' anxiety and therefore may enhance subjective recovery rate and satisfaction of hospitalization.

Periogen is a new caries activity test using real-time polymerase chain reaction. The aim of this study was to assess the validity of Periogen by evaluating the correlation with dmft, dmfts indices and comparing with Cariview and caries risk assessment tool (CAT).83 children under 6 participated in this study. Dmft, dmfts indices and CAT were collected through an examination of oral health status. Plaque samples for Periogen and Cariview were collected and manipulated according to the manufactures' instructions.The correlation coefficient of Periogen, Cariview and CAT with the dmfts index were 0.38, 0.56 and 0.66 in each (p < 0.01). The sensitivity of Periogen, Cariview and CAT were 43%, 76% and 95% and specificity were 80%, 72% and 74% respectively. Area under curve under the receiver operating characteristic curves in each method indicated 0.69, 0.81 and 0.85.CAT and Cariview were more effective in evaluation the risk of dental caries than Periogen so far. To be used Periogen clinically, more improvements for higher validity were needed.

The conventional radiologic method for liver segmentation is based on the position of the hepatic and portal veins. However, during surgery, liver segments are resected based on the distribution of hepatic portal blood flow. This discrepancy can lead to a number of problems, such as miscommunication among clinicians, missing the location of the segment with the hepatic mass, and the risk of extended hepatic resection. We suggest a novel method to determine hepatic segments based on portal blood flow, as in the surgical approach, but by using high and low mechanical indexes in contrast-enhanced ultrasonography with Sonazoid. This approach is helpful for preoperatively determining hepatic segments and reducing the risk of missing the location of a hepatic tumor or extended hepatic resection.

Background:
As the population rapidly ages, older adults are increasingly likely to experience mobility problems. This study aims to explore the characteristics related to an elderly person’s willingness to live in a nursing home if they have mobility problems Methods: This study analyzed data from 9,917 older adults (5,976 young-old and 3,941 old-old) obtained from the 2020 National Survey of Older Koreans. The dependent variable was the intended place of residence for older adults with mobility problems.Independent variables included various characteristics: (1) sociodemographic and social support, (2) health and functional status, and (3) residential environment. Rao-Scott chi-square tests and survey logistic regression analyses were performed for the young-old and old-old, respectively.
Results:
The intention to live in a nursing home was significantly different between the young-old (30.4%) and the old-old (34.7%) (p=0.009). According to fully adjusted multivariable analyses, for the young-old, the odds ratio of intending to live in a nursing home was significantly higher in social security benefit recipients (1.45; 95% confidence interval [CI], 1.06–1.97) compared to other individuals. The odds ratio was higher in unmarried (divorced, separated, widowed, or never-married) individuals for both young-old (1.41; 95% CI, 1.22–1.63) and old-old (1.34; 95% CI, 1.09–1.65) age groups, compared to their respective married counterparts.
Conclusion
The results of this study suggest that in an aging society, health and social policies should be designed considering the different characteristics of the elderly to improve their health, function, and quality of life.

BACKGROUND/AIMS: The purpose of this study was to assess the value of acoustic radiation force impulse (ARFI) for predicting the extent of radiofrequency ablation (RFA) in hepatocellular carcinoma (HCC) by correlating the elasticity of HCC and peritumoral parenchyma (as measured by ARFI) with the extent of ablation determined by computed tomography (CT). METHODS: From September 2009 to June 2011, 158 patients underwent RFA ablation for HCC (single, < or =3 cm). We evaluated the data of a total of 38 prospectively enrolled patients who underwent both ARFI imaging and contrast-enhanced CT after one session of 12 minutes of RFA without a change in needle position. The ARFI imaging indices, including the mean shear wave velocity (SWV) of HCC, mean SWV of the peritumoral parenchyma and tumor size, were evaluated to determine the statistical correlation with RFA extent after one session of 12 minutes of RFA. RESULTS: A stiffer liver parenchyma in patients with cirrhosis results in a smaller ablation zone. CONCLUSIONS: SWV of ARFI in liver parenchyma was well correlated with RFA extent. After evaluating the correlation between ARFI and RFA extent, we suggest that the SWV in liver parenchyma might be a non-invasive supplementary tool for predicting the extent of RFA.
