In patients with thyroid nodules, ultrasonography (US) has been established as a primary diagnostic imaging method and is essential for treatment decision. The Korean Thyroid Imaging Reporting and Data System (K-TIRADS) is a pattern-based, US malignancy risk stratification system that can easily diagnose nodules during real-time ultrasound examinations. The 2021 K-TIRADS clarified the US criteria for nodule classification and revised the size thresholds for nodule biopsy, thereby reducing unnecessary biopsies for benign nodules while maintaining the appropriate sensitivity to detect malignant tumors in patients without feature of high risk thyroid cancer. Thyroid radiology practice has an important clinical role in the diagnosis and non-surgical treatment of patients with thyroid nodules, and should be performed according to standard practice guidelines for proper and effective clinical care.

Variable systemic diseases affect larynx and vocal fold and result in voice change. Asthma and chronic obstructive pulmonary disease make increase of intra-abdomimal pressure followed by reflux of gastric acid, which stimulate vagal-bronchopulomary reflex aggravating cough and respiratory disturbance. Fungal laryngitis in the general population is extremely rare, but can occur in immunocompromised AIDS patients. Although, initially, empirical antifungal therapy for candidiasis is often given without biopsy, diagnostic direct laryngoscopy and biopsy is imperative if a substantial clinical response is not rapidly achieved. In the highly active anti-retroviral therapy era, HIV-positive patients are living longer and are at higher risk for developing non-AIDS-defining malignancies. The incidence of head and neck cancer (HNC) which is related with human papilloma virus infection has increased. The survival is significantly lower among the AIDS-HNC patients with CD4 counts ${\leq}200cells/{\mu}L$. Rheumatoid arthritis (RA) cause voice disturbance by developing cricoarytenoid joints fixation or nodule on vocal fold. Post-menopausal voice disorder (PMVD) is caused by decreased secretion of estrogen-progesterone resulting in decrease of fundamental frequency (F0). Hormonal replacement therapy is helpful to reduce F0 decrease. RA and PMVD result in slight voice change, but it could crucial in professional voice user.
Purpose: The purpose of this study was to evaluate the effectiveness of patient education interventions on distress, self-care knowledge and self-care behavior in cancer patients. Methods: A total of 1,102 studies were retrieved from 6 electronic databases in Korea. From these studies, 18 studies met the inclusion criteria with a total of 850 participants. Two authors independently assessed the methodological quality by Cochrane's Risk of Bias and Methodological Items for Non Randomized Studies. The data were analyzed by the RevMan 5.1 program of Cochrane library. Results: Overall effect size of education interventions on anxiety was -2.12 (95% CI:-3.90, -0.34) (p<.001). The effects on self-care knowledge and self care behavior were -1.08 (95% CI:-1.73, -0.43) (p=.001), and -1.41 (95% CI:-2.13, -0.68) (p<.001), respectively. Publication bias was detected as evaluated by funnel plot, but the fail-safe number was moderate. Conclusion: This study suggests that patient education interventions can relieve anxiety and self-care. Further randomized controlled trials studies are needed to evaluate the effects of patient education intervention on depression.
Burden of disease analysis provides a unique perspective on health by integrating fatal and non-fatal outcomes, yet allows the outcome of two classes to be examined separately. Although many studies have shown the inequality in health outcomes across socioeconomic status (SES), an analysis and comparison of Disability Adjusted Life Year (DALY) between different socioeconomic groups has been rare. This paper calculates the DALY and analyzes the distribution of DALYs for different SES. This study draws from 3,278 cases from the survey on "The Livelihood and Welfare Needs of the Elderly (2004)". It first provides a comprehensive assessment of the burden of 10 chronic diseases of the elderly based on DALY. Then this paper analyzes inequalities in the burden of disease by the levels of SES such as education, income, family size, occupation, and subjective economic conditions. For the elderly, the burden of disease is the highest for hypertension, arthritis and cancer. DALY rate per 1,000 people for the most socio-economically disadvantaged group is expressed as a multiple of the standardized rate for the least disadvantaged group (Rate Ratios). Family size is strongly related to. the difference in the burden of disease between SES groups, and the elderly Who live alone have higher DALY rate than those who live with their family. Other significant variables related to SES groups include subjective economic conditions, occupation, elderly income, and household income.

Recently, the population of patients who refuse transfusion has increased for both religious and non-religious reasons, even in life threatening emergency situations. Their refusal has highlighted the need to develop nonblood transfusion surgery techniques to decrease the risk from blood transfusions. A 57-year woman with an ulcerative lesion on the gingiva of the right upper molar area visited the department of oral and maxillofacial surgery in Dankook University Dental Hospital. After a preliminary evaluation, the patient was diagnosed with squamous cell carcinoma. As she refused blood transfusion during surgery for religious reasons, surgery was planned using recombinant human erythropoietin (rHuEPO) without a blood transfusion. The patient underwent a partial maxillectomy, supraomohyoid neck dissection, free radial forearm flap and split thickness skin graft under general anesthesia. rHuEPO and iron were used before and after surgery. The hemoglobin/hematocrit (Hb/Hct) level, iron (Fe) and total iron-binding capacity (TIBC) were assessed. The patient recovered completely without any blood transfusions. rHuEPO is a viable alternative for patients with religious objections to receiving blood transfusions.

Seizure is a foreseeable risk in patients with brain lesion. However, seizure during treating non-brain lesion is not a familiar situation to neurosurgeon. Posterior reversible encephalopathy syndrome (PRES) is a relatively common situation after systemic chemotherapy. The aim of this study is to make neurosurgeons aware of this potential medical problem. A 52-year-old woman with advanced gastric cancer, presented with low back pain due to spinal metastasis at the 4th lumbar vertebra. Ten cycles of chemotherapy with FOLFOX (5-Fluoruracil/Oxaliplatin) had been completed 23 days ago. Two days before the planned operation, a generalized tonic clonic seizure occurred. She did not have a history of hypertension or seizure. The seizure was stopped with lorazepam 4mg. The brain magnetic resonance (MR) imaging showed high signal changes in both parieto-occipital lobes on the T2-weighted images, and these were partially enhanced, suggesting PRES. The surgery was preceded by treatment with an antiepileptic drug. The MR images, taken 1.5 months after the seizure, showed that the lesion was no longer present. At 3 month follow-up, no additional seizure attack occurred without any seizure medication. The possibility of a seizure attack should be considered if the patient has a history of chemotherapy.
The cutaneous melanoma has been regarded as rare disease entity in Korea for long time but it shows a silent growth recently. Furthermore the management of cutaneous melanoma including staging system, surgical principle, sentinel lymph node biopsy and subsequent complete node dissection and, most importantly, immunotherapy and target therapy against cutaneous melanoma recently. The incidence of cutaneous melanoma is steadily increasing in Korea but its increase is rapid recent 2 decades to 4.3 times and should be greater soon according to the steeper increase of life expectancy. New staging system proposed by American Joint Committee on Cancer (2017) includes changes in individual TNM category and stage groups, particularly from a prognostic viewpoint. Dermoscopy has been successfully introduced in the differential diagnosis of pigmented skin lesion focusing on cutaneous melanoma by non-invasive simple diagnostic tool. Sentinel lymph node biopsy was a issue of long debate whether survival benefit is real or not. Temporary conclusion about this question is reached after two large scale studies and immediate complete node dissection should be performed in a certain situations. Most important change is drug therapy focusing on immunotherapy and target therapy. Braf- and MEK-inhibitor, immune checkpoint inhibitor and PD-1 blocker has been proved to be effective as a sole or combination regimen against advanced and/or high-risk adjuvant setting of cutaneous melanoma. In conclusion, these remarkable changes will be reviewed shortly here.

BACKGROUND/OBJECTIVES: It is difficult to consistently demonstrate the health effects of soy isoflavones owing to the multitude of factors contributing to their bioavailability. To accurately verify these health effects, dietary isoflavone intake should be measured using a biologically active dose rather than an intake dose. This concept has been expanded to the development of new exposure biomarkers in nutrition research. This review aims to provide an overview of the development of exposure biomarkers and suggest a novel research strategy for identifying the health effects of soy isoflavone intake. MATERIALS/METHODS: We cover recent studies on the health effects of soy isoflavones focusing on isoflavone metabolites as exposure biomarkers. RESULTS: Compared to non-fermented soy foods, fermented soy foods cause an increased concentration of isoflavones in the biofluid immediately following ingestion. The correlation between exposure biomarkers in blood and urine and the food frequency questionnaire was slightly lower than that of corresponding 24-h dietary recalls. Urinary and blood isoflavone levels did not show a consistent association with chronic disease and cancer risk. CONCLUSION: It is crucial to understand the variable bioavailabilities of soy isoflavones, which may affect evaluations of soy isoflavone intake in health and disease. Further studies on the development of valid exposure biomarkers are needed to thoroughly investigate the health effects of isoflavone.
Objectives : This study examined the association between depression and survival time in terminal cancer patients admitted to the palliative care unit. Emotional problems are important for terminal cancer patients in the palliative care unit, and evaluation of patients' depression plays an important role in treatment planning. Methods : From October 2015 to August 2018, we conducted a retrospective study of 291 terminal cancer patients admitted to a palliative care unit at a university hospital and evaluated depression with PHQ-9 at admission. Of the 291 patients, 146 (50.2%) completed PHQ-9 but 145 (49.8%) were not evaluated due to loss of consciousness or rejection. Results : 4-week survival rate in the Kaplan-Meier survival analysis were 45.4% in the non-depressed group (PHQ-9<10) and 18.7% in the depressed group (PHQ-9≥10). According to the severity of depression, in the Cox proportional hazard model, the risk of mortality in moderate, moderately sever and severe group was 2.778, 1.882 and 3.423 times higher than minimal group, respectively. Conclusions : Of the patients with terminal cancer who were admitted to the palliative care unit, the survival time was shorter in the depressed group than in the non-depressed group. Further research is needed to determine if treatment of depression increase the survival in terminal cancer patients.
Background : It has been generally known that the incidence of lung cancer is higher in the patients with idopathic pumonary fibrosis (IPF) than those in general population. The reported incidence was variable from 4.8 to 43.2%. There were controversies on the most frequent cell type (squamous cell carcinoma vs. adenocarcinoma) and no study was done about the real concordance of cancer and the fibrotic lesion. And the pulmonary fibrosis may influence not only the development of cancer but also the treatment and prognosis of the cancer, but there was no report on that point. Method : Total 63 patients ($66.8{\pm}7.8$ year, M : F=61 : 2) were diagnosed as IPF combined with lung cancer (IFF-CA) at Asan Medical Center. A retrospective analysis was done about the risk factors of the lung cancer, pulmonary function test, the site of cancer(especially the relationship of the cancer with the fibrotic lesion), the histologic types, and the stage of cancer. The histologic types were compared with those of 2,660 patients with lung cancer who were diagnosed at the same institute for the same period. The effect of IPF on the treatment of the cancer was evaluated with the survival time after the detection of lung cancer. Results : The lung cancer was found in 63(22.9%) out of 281 patients with IPF. But in most of them(45 patients), lung cancer was detected at the same time with IPF and only in 18 patients, the cancer was diagnosed during the follow-up($25.2{\pm}17.7$ months) of IPF. So in our study, 6.7% of patients with IPF developed lung cancer during the course of the disease. The age ($66.8{\pm}7.84$ vs. $63.4{\pm}11.1$ years), percentage of smoker (88.9 vs. 67.2%), and the male gender (96.8 vs. 67.6%) were significantly higher in IPF-CA compared with lone IPF (p<0.05). The odds ratio of smoking was 4.7 compared with non smoking IPF controls. The lung cancer was located more frequently in the upper lobe and 55.5% was in the periphery of lung. The cancer was developed in the fibrotic lesion in 23 patients (35.9%), and in the majority of the patients, the cancer was separated from the fibrosis. The cell type of the lung cancer in IPF-CA was squamous cell carcinoma 34.9%, adenocarcinoma 30.2%, small cell carcinoma 19.0%, large cell undifferenciated carcinoma 6.3%, and others 9.5%. No significant difference in the distribution of histologic type of the lung cancer was found between IPF-CA and lone lung cancer. There was no significant difference in demographic features, cell types, location and the stage of the cancer between the group with concurrent IPF-CA and the group with cancer diagnosed during the follow up of IPF. There was a tendency (but statistically not significant : p=0.081) of higher incidence of adenocarcinoma among the cancers developed in the fibrotic area(43.5%) (F-CA) than in the cancers in non-fibrotic area (22.5%) (NF-CA). The prognosis of the patients with F-CA was poor (median survival : 4 months) compared with the patients with NF-CA (7 months, p=0.013), partly because the prevalence of severe IPF (the extent of fibrosis in HRCT 50%) was higher in F-CA group. Conclusion : These data suggest that the lung cancer in the patients with IPF has similar features to the ordinary lung cancer.
