Hematological malignancies rarely affect the breast, and the majority of those that do are lymphomas. In this review, we describe the clinical aspects and multimodal imaging findings of breast lymphoma. We also illustrate the key clinical and radiological findings that allow it to be distinguished from various other malignant and benign diseases of the breast. Breast lymphoma manifests as a breast mass, a change in the subcutaneous tissue or the skin, or enlargement of the associated lymph node on radiological examination. Radiological findings associated with other breast malignancies, such as calcifications, spiculations, or architectural distortions are extremely rare. Skin and subcutaneous changes frequently accompany T-cell lymphoma. Multimodal breast imaging characteristics may aid in the diagnosis of breast lymphoma.

OBJECTIVE: Measure the over-expression of p73 and analyze as the prognostic as well as angiogenic factor of cervical cancer by comparing the degree of expression of VEGF and TSP-1 by RT-PCR. METHODS: 7 normal and 37 cervical cancer specimens were put through RT-PCR and the expression of p73, VEGF and TSP-1 were measured. After immunohistochemical staining, the number of microvessels was counted. With the level of expression, investigated the relationship with the clinicopathological characteristics and the number of microvessels. RESULTS: 57% of cancer tissues showed abnormally high levels of p73 mRNA. In quantitative genomic DNA PCR, the p73 was over-expressed in the transcription level. Through allotyping with Sty I polymorphism, the over-expression of p73 was due to the transcription activity of the silent allele. In RT-PCR-SSCP analysis of over-expressed specimens, sequence alterations was not seen. In 73%, VEGF was over-expressed while TSP-1 was under-expressed in 35%. There was no association between the number of microvessels with the over-expression of p73 and VEGF, but inversely associated with the under-expression of TSP-1. There was no correlation between the over-expression of p73 and the clinicopathological characteristics. The over-expression of p73 coincided 80% with the over-expression of VEGF, and 40% with the under-expression of TSP-1. CONCLUSION: These data support the expression of p73 was increased in cervical cancer tissues and was associated with the over-expression of the VEGF but not associated with the under-expression of TSP-1. The biological and clinical significance of the over-expression of p73 should be studied further in the future.

OBJECTIVES: Menopause is a natural aging process causing estrogen deficiency, accelerating atherogenic processes including dyslipidemia. Prevalence of thyroid dysfunction is also high in postmenopausal women, and it is known to elevate the risk of cardiovascular disease (CVD). Therefore, we are to study on the associations in between serum thyroid stimulating hormone (TSH) and prevalence of CVD in postmenopausal women who have normal thyroid function. METHODS: We performed a retrospective review of 247 Korean postmenopausal women who visited the health promotion center from January, 2007 to December, 2009. Postmenopausal women with normal serum TSH were included in the study. Coronary atherosclerosis was assessed by 64-row multidetector computed tomography. RESULTS: In multiple linear regression analysis, serum TSH was associated with serum triglyceride (TG) (β = 0.146, P = 0.023). In multiple logistic regression analysis, increasing age and serum TSH were associated with an increased risk of coronary atherosclerosis in euthyroid postmenopausal women (odds ratio [OR] = 1.107 [1.024-1.197], P = 0.011 and OR = 1.303 [1.024-1.658], P = 0.031, respectively). CONCLUSIONS: It revealed that significant predictor of serum TSH was serum TG, and increasing age and TSH were found to have associations with an increased risk of coronary atherosclerosis in euthyroid postmenopausal women. Screening and assessing risks for CVD in healthy postmenopausal women would be helpful before atherosclerosis develops.

Purpose: The purpose of this study is to investigate the factors influencing oncology unit nurses’ pain management of cancer patients. Methods: This study was a designed descriptive correlation study. The participants of this study were nurses working in an oncology unit at a university hospital. A total of 135 nurses participated and data were collected between October 10 and October 31, 2018. Measures used for this study assessed nurses’ knowledge of cancer pain management, compassion competence, and the performance of cancer pain management. The data were analyzed using independent t-test, ANOVA, Pearson’s correlation coefficient, and multiple linear regression analysis. Results: Performance of cancer pain management was significantly correlated with compassion competence (r=0.37, p<.001) and difference according to the experience of cancer by the participants or family members (t=2.22, p=.028). Performance of cancer pain management was influenced by compassion competence (β=.36,p<.001) and the experience of cancer by the participants or family members (β=.17, p=.041). The explanatory power of this model was 14.4%. Conclusion These results suggest the need for cancer pain management education based on compassion empowerment. The findings shows that continuous cancer pain management education is required in consideration of the oncology nurses’ career and work characteristics.

Background: and PurposeIn 2021, lung cancer in school food workers was first recognized as an occupational cancer. The classification of the carcinogenicity of cooking fumes by International Agency for Research on Cancer (IARC) was based on Chinese epidemiological data. This study aimed to determine the hazard levels of school cooking fumes in Korea. Materials and Methods: Based on public school cafeterias in one area, 25 locations were selected for the survey according to the number per school type, ventilation states, and environmental pre-assessments of cafeterias. Two inside cooking areas using a heat source and one outside cooking area were selected as control measurement points. Measurements of CO, CO2, polycyclic aromatic hydrocarbons (PAHs), and total volatile organic compounds (TVOCs), including benzene, formaldehyde, and particulate matter (PM10, PM2.5, PM1, respectively), were taken. The concentrations and patterns of each substance in the kitchens were compared with the outdoor air quality.ResultKnown carcinogens, such as the concentrations of PAHs, formaldehyde, TVOC (benzene), and particulate matter in school cooking fumes, were all detected at similar or slightly higher levels than those found outside. Additionally, substances were detected at relatively low concentrations compared to the Chinese cooking fumes reported in the literature. However, the short-term exposure to high concentrations of CO (or composite exposure with CO2) and PM2.5 in this study were shown. Conclusion The school cooking fumes in South Korea was a relatively less harmful than Chinese cooking fumes, however short-term, high exposure of toxic substances can cause a critical health effect.

Purpose: This study aimed to identify and compare the risk factors of depression among middle-class Korean workers. Methods: A cross sectional study was designed for secondary data analysis. From the 8th Korean Medical Panel Survey (2008~2013), a total of 3,056 data was drawn and analyzed. With SPSS version 24, a developmental stage comparison, with the stage being young adults (20~39), middle-aged adults (40~64), and older adults (65+) were conducted. Frequency, percentage, x 2 test and logistic regression analysis were statistical tools used to analyze the data. Results: In all developmental groups, experience of frustration was found to be a common risk factor of depression. Stress from excessive task, peer-compared subjective health status, and self-perceived social class were risk factors of depression in the young adults and the middle-aged adults. Anxiety for the future significantly influenced depression in the middle-aged adults and older adults. Conclusion Experience of frustration was a major risk factor of depression among Korean middle-class workers. Interventions to reduce depression need to be developed focusing on the specific risk factors by developmental stages such as experience of frustration, stress from task burden, poor peer-compared subjective health status and anxiety for the future.

BACKGROUND/OBJECTIVES: This study was conducted to evaluate the feasibility of a sodium reduction program at local restaurants through nutrition education and examination of the health of restaurant owners and cooks. SUBJECTS/METHODS: The study was a single-arm pilot intervention using a pre-post design in one business district with densely populated restaurants in Seoul, South Korea. The intervention focused on improving nutrition behaviors and psychosocial factors through education, health examination, and counseling of restaurant personnel. Forty-eight restaurant owners and cooks completed the baseline survey and participated in the intervention. Forty participants completed the post-intervention survey. RESULTS: The overweight and obesity prevalences were 25.6% and 39.5%, respectively, and 74.4% of participants had elevated blood pressure. After health examination, counseling, and nutrition education, several nutrition behaviors related to sodium intake showed improvement. In addition, those who consumed less salt in their baseline diet (measured with urine dipsticks) were more likely to agree that providing healthy foods to their customers is necessary. This study demonstrated the potential to reduce the sodium contents of restaurant foods by improving restaurant owners' and cooks' psychological factors and their own health behaviors. CONCLUSIONS: This small pilot study demonstrated that working with restaurant owners and cooks to improve their own health and sodium intake may have an effect on participation in restaurant-based sodium reduction initiatives. Future intervention studies with a larger sample size and comparison group can focus on improving the health and perceptions of restaurant personnel in order to increase the feasibility and efficacy of restaurant-based sodium reduction programs and policies.

PURPOSE: We wanted to determine whether additional breast ultrasound examinations are needed for patients who have clustered calcifications found by mammography for the detection of breast carcinomas. METHODS: We performed targeted ultrasound examinations in 125 consecutive patients who had clustered calcifications found by mammography. Forty-eight pathologically proven patients with 61 breast lesions were included in this study (26 invasive carcinomas, 10 ductal carcinomas in situ and 25 benign diseases). Two breast radiologists evaluated the mammography and the ultrasound findings and they graded the probability of malignancy by consensus as follows: definitely benign 1, probably benign 2, probably malignant 3, and definitely malignant 4. The diagnostic performance values, including the sensitivity, specificity, accuracy, positive predictive value and negative predictive value, for mammography and additional ultrasound were compared using McNemar's test and receiver operating characteristic (ROC) analysis. On the ROC analysis, areas under the ROC curves (AUC) and 95% confidence intervals (CI) were obtained. RESULTS: The sensitivity, specificity, accuracy, positive predictive value, and negative predictive value for making the diagnosis of breast carcinoma by mammography were 88.9%, 12.0%, 57.4%, 59.3%, and 42.9% and those for additional ultrasound were 94.4%, 64.0%, 82.0%, 79.1%, and 88.9%, respectively. The differences of specificity and accuracy were statistically significant (p=0.0003). On the ROC analysis, ACU were significantly different between mammography (AUC=0.586, 95% CI=0.453-0.711) and ultrasound (AUC=0.823, 95% CI=0.704-0.909) (p=0.003). Clustered calcifications with associated masses or ductal changes on additional breast ultrasound had high frequency of malignancies, 79% or 73%. In addition, 87% of malignant masses were invasive carcinomas and 45% of malignant ductal changes were ductal carcinomas in situ. CONCLUSION: Additional breast ultrasound examinations for the lesions with clustered calcifications on mammography can improve the diagnostic performance and significantly contribute to the specificity and accuracy of a diagnosis of breast carcinoma. In addition, the ultrasound features may predict the pathologic findings such as benignity or malignancy and invasive carcinoma or ductal carcinoma in situ.

PURPOSE: Because migraine in children has different characteristics from that in adults, it is inappropriate to apply migraine criteria for adults to children. Recently, the International Headache Society(IHS) revised criteria regarding children's characteristics. Therefore, we reviewed the characteristics of childhood migraines without auras based on the revised criteria and compared the data with the findings of childhood migraine by the previous criteria. METHODS: Among 102 children who visited the outpatient clinic of Kangbuk Samsung Hospital for the chief complaint of headache, we analyzed the clinical findings of 34 patients, who were diagnosed as migraine without aura, and probable migraine based on the revised criteria. RESULTS: Migraines without aura were diagnosed in 27 patients(26.5 percent) and probable migraines were observed in seven patients(6.8 percent). The usual duration of headache attacks over 2 hours was observed in 12 patients(44.4 percent). On the contrary, 15 patients(55.6 percent) usually experienced headaches for one to two hours. According to the location of headaches, there were temporal areas in 14 cases, frontal areas in nine cases, occipital areas in two cases and diffuse areas in two cases. The striking point in probable migraines is that the length of headache was below one hour in five patients. Nine patients were diagnosed as migraine without aura, when the first edition criteria was applied to same patients. CONCLUSION: We found that the prevalence of migraine without aura increased by the revision of IHS criteria. We hope that migraines in children will be diagnosed correctly by the new IHS criteria.

PURPOSE: To investigate the clinical use of low-dose multidetector row computed tomography (MDCT) for staging of invasive breast cancers with patients in the prone position. METHODS: Three hundred twenty-two patients with 334 pathologically-verified breast cancers had low-dose MDCT breast imaging in the prone position for tumor staging before treatment between May 2006 and June 2010. We designed an additional computed tomography table pad with a hole for prone positioning. Patients lay prone on the table pad and the breasts were positioned within the rectangular hole. We obtained dynamic breast imaging from the lower neck to the lung base with the following parameters: 120 kVp, 50 mAs, and 3-mm reconstruction intervals. We evaluated the extent of the primary tumor, lymph nodal status, and distant metastasis in lung or bone, then assessed tumor staging based on the TNM classification of breast cancer. The assessed staging compared to the pathologic results for diagnostic accuracy. RESULTS: Among the 334 invasive breast cancers, the overall diagnostic accuracy of tumor staging was 88.3% and the accuracy values of each tumor stage were 89.6% in T1, 90.8% in T2, 81.0% in T3, and 89.3% in T4. The overall diagnostic accuracy of lymph nodal staging was 86.3% and the accuracy values in each nodal stage were 82.9% in N0, 88.0% in N1, 89.7% in N2, and 93.3% in N3. Based on breast computed tomography scans, we detected distant metastases in 30 cases (7 lungs, 10 bones, 7 lungs and bones, and 6 livers). CONCLUSION: Low-dose MDCT scanning for invasive breast cancer patients in the prone position is a feasible imaging technique for tumor staging before treatment to evaluate primary breast tumors, lymph nodes, lungs, or thoracic bones with reduced radiation doses.
