Quality of life outcomes from the randomized trial of hyperthermic intraperitoneal chemotherapy following cytoreductive surgery for primary ovarian cancer (KOV-HIPEC-01) / 부인종양

Objective@#To investigate the health-related quality of life (HRQOL) related to hyperthermic intraperitoneal chemotherapy (HIPEC) following primary or interval cytoreductive surgery for primary ovarian cancer. @*Methods@#Between 2010 and 2016, a total of 184 patients were randomly assigned to receive cytoreductive surgery with HIPEC (n=92) or without HIPEC (n=92). Quality of life (QOL) assessment was evaluated at baseline (before surgery); on postoperative day 7; after the 3rd and 6th cycle of adjuvant chemotherapy; and at 3, 6, 9, and 12 months after randomization. Patient-reported QOL was assessed using the European Organization for Research and Treatment of Cancer (EORTC) core questionnaire (EORTC-QLQ-C30), ovarian cancer questionnaire modules (QLQ-OV28), and the MD Anderson Symptoms Inventory (MDASI). @*Results@#Of the 184 patients enrolled, 165 (83/92 in the HIPEC group and 82/92 in the control group) participated in the baseline QOL assessment. There were no statistically significant differences in functional scales and symptom scales in QLQ-C30; symptom scales, including gastrointestinal symptoms QLQ-OV28; and severity and impact score in MDASI between the 2 treatment groups until 12 months after randomization. @*Conclusion@#HIPEC with cytoreductive surgery showed no statistically significant difference in HRQOL outcomes. Thus, implementation of HIPEC during either primary or interval cytoreductive surgery does not impair HRQOL.

Gender-based Multilevel Analysis of Influential Factors for Suicide Attempts among At-risk Non-referred Adolescents in Korea

Objective@#Effective suicide prevention for at-risk adolescents requires increased access to medical treatment. Investigating the unique characteristics of suicide in this vulnerable at-risk non-referred sample can contribute to establishing effective suicide prevention policies. This study aimed to (a) examine at-risk non-referred adolescents’ suicide attempt rate, (b) investigate influential multilevel factors in predicting these adolescents’ suicide attempts, and (c) compare the results of (a) and (b) by gender. @*Methods@#A total of 401 samples (216 boys and 185 girls) were recruited through a school-based mental health project for at-risk adolescents. Multivariate hierarchical logistic regression analyses were performed at the individual-, contextual-, and protective levels to evaluate three multilevel models as well as to investigate predictabilities for the overall group and by gender. @*Results@#The suicide attempt rate of the overall sample was 29.4% (boys: 18.1%, girls: 42.7%), which was significantly higher than that of community samples. For boys, individual-level predictors (depression and conduct problems) had the most significant contribution in predicting suicide attempts. In contrast, for girls, protective-level predictors (family satisfaction) contributed the most to the prediction of suicide attempts, followed by contextual-level predictors (academic grades). @*Conclusion@#This study is an important step in understanding the unique characteristics of at-risk non-referred adolescents who have not yet been considered in mental health policies. Improving medical accessibility will be the first step in establishing effective suicide prevention policies for these vulnerable samples.

Development and Validation of Ovarian Symptom Index-18 and Neurotoxicity-4 for Korean Patients with Ovarian, Fallopian Tube, or Primary Peritoneal Cancer / Journal of the Korean Cancer Association, 대한암학회지

PURPOSE: The purpose of this study was to develop Korean versions of the National Comprehensive Cancer Network/Functional Assessment of Cancer Therapy (NCCN-FACT) Ovarian Symptom Index-18 (NFOSI-18) and FACT/Gynecologic Oncology Group (FACT-GOG) Neurotoxicity 4-item (NTX-4), evaluating their reliability and reproducibility. MATERIALS AND METHODS: In converting NFOSI-18 and NTX-4, the following steps were performed: forward translation, backward translation, expert review, pretest of preliminary format, and finalization of Korean versions (K-NFOSI-18 and K-NTX-4). Patients were enrolled from six institutions where each had completed chemotherapy for ovarian, tubal, or peritoneal cancer at least 1 month earlier. In addition to demographics obtained by questionnaire, all subjects were assessed via K-NFOSI-18, K-NTX-4, and a Korean version of the EuroQoL-5 Dimension. Internal structural validity and reliability were evaluated using item internal consistency, item discriminant validity, and Cronbach's α. To evaluate test-retest reliability, K-NFOSI-18 and K-NTX-4 were readministered after 7-21 days, and intraclass correlation coefficients (ICCs) were calculated. RESULTS: Of the 250 women enrolled during the 3-month recruitment period, 13 withdrew or did not respond, leaving 237 (94.8%) for the analyses. Mean patient age was 54.3±10.8 years. Re-testing was performed in 190 patients (80.2%). The total K-NFOSI-18 and K-NTX-4 scores were 49 (range, 20 to 72) and 9 (range, 0 to 16), respectively, with high reliability (Cronbach's α=0.84 and 0.89, respectively) and reproducibility (ICC=0.77 and 0.84, respectively) achieved in retesting. CONCLUSION: Both NFOSI-18 and NTX-4 were successfully developed in Korean with minimal modification. Each Korean version showed high internal consistency and reproducibility.

Validation of the Korean version of visual analogue scale for irritable bowel syndrome questionnaire for assessment of defecation pattern changes

PURPOSE: Patients often complain of change of defecation pattern and it is necessary to quantify their symptoms. To quantify symptoms, use of questionnaire is ideal, so we adopted a simple and easily writable visual analogue scale for irritable bowel syndrome questionnaire (VAS-IBS). The aim of this study was to develop and validate the Korean version of VAS-IBS questionnaire (Korean VAS-IBS) that can adequately reflect the defecation pattern. METHODS: This study translated English VAS-IBS into Korean using the forward-and-back translation method. Korean VAS-IBS was performed on 30 patients, who visited the outpatient clinic and had no possibility of special defecation pattern. Detailed past medical history and Bristol stool chart was added to the questionnaire. The survey was conducted twice, and the median interval between the 2 surveys was 10 days (8–11 days). Cronbach α for internal consistency reliability and intraclass correlation coefficients for test-retest reliability were analyzed. RESULTS: Korean VAS-IBS achieved acceptable homogeneity with a Cronbach α coefficient of 0.66–0.79 showing adequate internal consistency reliability. In addition, intraclass correlation coefficients showed significant test-retest reliability with 0.46–0.80 except for the question assessing the “perception of psychological wellbeing.” CONCLUSION: The Korean VAS-IBS is a valid and reliable questionnaire for the measurement of the symptoms of defecation pattern changes.

Comparison of Quality of Life and Sexuality between Cervical Cancer Survivors and Healthy Women / Journal of the Korean Cancer Association, 대한암학회지

PURPOSE: The purpose of this study is to compare quality of life (QoL) and sexual functioning between sexually active cervical cancer survivors and healthy women. MATERIALS AND METHODS: In this cross-sectional study, propensity-score-matched cervical cancer survivors (n=104) and healthy women (n=104) were compared. All women had engaged in sexual activity within the previous 3 months, and cervical cancer survivors showed no evidence of disease after primary treatment. QoL and sexual functioning were assessed using three questionnaires; the European Organization for Research and Treatment of Cancer Quality of Life Questionnaire Core 30 (EORTC QLQ-C30), Cervical Cancer Module (EORTC QLQ-CX24), and the Female Sexual Function Index (FSFI). RESULTS: Significantly higher scores for lymphedema were observed in the cervical cancer survivors group compared with the healthy women group (mean, 20.2 vs. 12.2; p < 0.05). Sexuality, both in terms of sexual activity, sexual enjoyment, and sexual worry (EORTC QLQ-CX24), and in terms of desire, arousal, lubrication, orgasm, satisfaction, and pain (FSFI) were similar between the groups. When the scale of sexual/vaginal functioning in EORTC QLQ-CX24 was divided into individual questions, cervical cancer survivors reported shorter vaginal length than the control group, but without statistical significance (mean, 80.6 vs. 85.4; p=0.077). CONCLUSION: Compared with healthy women, sexuality was not impaired in cervical cancer survivors who showed no evidence of disease after primary treatment and engaging in sexual activity. Further prospective cohort studies are warranted to confirm this finding.

Quality of life and sexuality comparison between sexually active ovarian cancer survivors and healthy women / 부인종양

OBJECTIVE: compare quality of life (QoL) and sexual functioning between sexually active ovarian cancer survivors and healthy women. METHODS: A cross-sectional study was performed in 103 successfully treated ovarian cancer survivors and 220 healthy women. All women had engaged in sexual activity within the previous 3 months, and ovarian cancer survivors were under surveillance after primary treatment without evidence of disease. QoL and sexual functioning were assessed using three questionnaires; the European Organization for Research and Treatment of Cancer Quality of Life Questionnaire-Core 30 (EORTC QLQ-C30), Ovarian Cancer Module (EORTC QLQ-OV28), and the Female Sexual Function Index (FSFI). Propensity score matching was used to adjust covariates between the ovarian cancer survivor and healthy women groups. In total, 73 ovarian cancer survivors and 73 healthy women were compared. RESULTS: Poorer social functioning (mean, 82.4 vs. 90.9; p=0.010) and more financial difficulties (mean, 16.4 vs. 7.8; p=0.019) were observed among ovarian cancer survivors than among healthy women. Sexuality, both in terms of desire, arousal, lubrication, orgasm, satisfaction, and pain and in terms of interest in sex, sexual activity, and enjoyment of sex (EORTC QLQ-OV28) were similar between the groups. However, vaginal dryness was more problematic in ovarian cancer survivors, with borderline statistical significance (p=0.081). CONCLUSION: Sexuality was not impaired in ovarian cancer survivors who were without evidence of disease after primary treatment and having sexual activities, compared with healthy women, whereas social functioning and financial status did deteriorate. Prospective cohort studies are needed.

Assessment of Breast Cancer Patients' Knowledge and Decisional Conflict Regarding Tamoxifen Use

Breast cancer is the most common type of female cancer. Tamoxifen, a selective estrogen receptor modulator, is widely used to decrease breast cancer recurrence and mortality among patients. However, it also increases the risk of endometrial cancer. This study aimed to assess knowledge and decisional conflict regarding tamoxifen use. Between June and October 2014, breast cancer patients using tamoxifen were consecutively screened and requested to complete a survey including the EQ-5D, Satisfaction with Decision Scale (SWD), Decisional Conflict Scale (DCS), and a self-developed, 15-item questionnaire measuring tamoxifen-related knowledge. The study sample comprised 299 patients. The mean total knowledge score was 63.4 of a possible 100.0 (range, 13.3-93.3). While 73.9% of the participants knew that tamoxifen reduces the risk of breast cancer recurrence, only 57.9% knew that the drug increases endometrial cancer risk. A higher education level (> or =college) was associated with a higher, total knowledge score (beta = 4.291; P = 0.017). A higher knowledge score was associated with a decreased DCS score (beta = -0.366; P < 0.001). A higher SWD score was also associated with decreased decisional conflict (beta = -0.178; P < 0.001). In conclusion, the breast cancer patients with higher levels of tamoxifen-related knowledge showed lower levels of decisional conflict regarding tamoxifen use. Clinicians should provide the exact information about tamoxifen treatment to patients, based on knowledge assessment results, so as to aid patients' decision-making with minimal conflict.

Development and Evaluation of Korean Version of Quality of Sexual Function (QSF-K) in Healthy Korean Women

This study was done to develop a Korean version of the Quality of Sexual Function (QSF-K) and evaluate the validity and reliability of the QSF-K. The participants were 220 women who visited the Center for Uterine Cancer at the National Cancer Center in Korea. Participants completed the scale once and then again at a two to four week interval. The QSF-K, Female Sexual Function Index (FSFI) and European Organization for Research and Treatment of Cancer Quality of Life Questionnaire Core 30 (EORTC-QLQ-C30) were used in this study. Receiver operating characteristics (ROC) curve, area under the ROC curve (AUC), intraclass correlation coefficients (ICC), and Cronbach's alpha were analyzed. In the analysis of the reliability, Cronbach's alpha was 0.83 and the ICC was 0.70. The validity measured with the AUC of the QSF-K comparing the FSFI and Global Health/QOL of the EORTC-QLQ-C30 was 0.717 and 0.728, respectively. Specifically, the AUC of the sexual activity level of the QSF-K was 0.838 in the FSFI comparison. The AUC of the psycho-somatic QOL of the QSF-K was 0.758 in the Global Health/QOL of the EORTC-QLQ-C30 comparison. Approximately half of the women (51.8%) had mild complaints/problems. The Korean version of the QSF was developed and validated.

Development and Validation of the Korean Version of the Female Sexual Function Index-6 (FSFI-6K)

PURPOSE: To evaluate the validity and reliability of the Korean version of the Female Sexual Function Index-6 (FSFI-6K). MATERIALS AND METHODS: Participants were recruited from February 2013 to July 2013. The primary survey was conducted for 220 participants, and a follow-up was conducted 3 weeks (+/-1 week) after the primary survey. The FSFI-6K data were analyzed and compared to the reference values in the original FSFI. RESULTS: Of the 220 participants, 199 (90.5%) returned to follow-up, 18 (8.2%) had no further contact, and 3 (1.4%) declined to respond. The internal consistency of the FSFI-6K as measured by Cronbach's alpha was 0.888 and the reliability based on test-retest intraclass correlation was 0.606; these values were acceptable. The cutoff used for diagnosis of female sexual dysfunction by an receiver operating characteristics (ROC) curve was a score of 21; the sensitivity and specificity for this curve are 0.89 and 0.86, respectively. The area under the receiver operating curve was 0.948. CONCLUSION: The FSFI-6K has high internal consistency and acceptable reliability. This validated questionnaire can be used for the Korean population.

A Case of Lactic Acidosis Caused by Linezolid Treatment of Persistent Methicillin-Resistant Staphylococcus Aureus Bacteremia / 대한내과학회지

Linezolid is an antibiotic in the oxazolidinone family that works as a bacterial protein synthesis inhibitor. It is used for the treatment of Gram-positive, multidrug-resistant bacteria. Adverse effects of linezolid include bone marrow suppression, peripheral or optic neuropathy, and, less commonly, lactic acidosis. Lactic acidosis usually occurs as a result of cardiopulmonary failure or sepsis, but it is sometimes caused by drugs, such as linezolid, and treatment of such lactic acidosis involves cessation of the drug. We report a case of lactic acidosis caused by the use of linezolid for the treatment of persistent methicillin-resistant Staphylococcus aureus bacteremia, which occurred after endoscopic sclerotherapy of gastic varices.

A Case of Pulmonary Alveolar Proteinosis Improved with Inhaled Granulocyte-Macrophage Colony-Stimulating Factor (GM-CSF) / 대한내과학회지

Pulmonary alveolar proteinosis (PAP) is a rare lung disease characterized by the accumulation of lipoproteinaceous material within the alveoli. Several studies have recently found that autoantibodies against granulocyte-macrophage colony-stimulating factor (GM-CSF) play a major role in the pathogenesis of idiopathic PAP. Consequently, inhaled or systemic injection of GM-CSF has been suggested as a promising treatment for PAP. A 54-year-old male visited our hospital for progressive dyspnea. Four years earlier, he was diagnosed with PAP based on a surgical lung biopsy in another institution. Whole-lung lavage was performed four times before he visited our hospital. We administered high-dose inhaled GM-CSF therapy for 12 weeks followed by 12 weeks of low-dose therapy. After the GM-CSF treatment, the patient's symptoms, lung function, and radiological findings were improved significantly.

A Case of Severe Community-acquired Acinetobacter baumannii Pneumonia with Bacteremia

Acinetobacter baumannii is a significant pathogen in nosocomial infections, especially in intensive care units. However, community-acquired A. baumannii (CAAB) pneumonia is an uncommon disease. Most of the CAAB pneumonia in the literature is characterized by an abrupt onset and rapid progression to respiratory failure and hemodynamic instability. In our case, a 51-year-old man without underlying diseases developed severe pneumonia. Respiratory distress rapidly worsened and mechanical ventilation was applied. Extra-corporeal membrane oxygenation was applied due to refractory septic shock. Fully sensitive A. baumannii pneumonia was confirmed by the sputum culture and blood culture. The patient was effectively treated by the meropenem. However, the patient died of uncontrolled ventilator-associated pneumonia, developed on the 10th hospital day, and refractory septic shock. We report the case of severe CAAB pneumonia with bacteremia in a patient without underlying diseases in Korea.

Drug rash with eosinophilia and systemic symptoms syndrome following cholestatic hepatitis A: a case report / 대한간학회지

Hepatitis A virus (HAV) infections occur predominantly in children, and are usually self-limiting. However, 75-95% of the infections in adults are symptomatic (mostly with jaundice), with the illness symptoms usually persisting for a few weeks. Atypical manifestations include relapsing hepatitis, prolonged cholestasis, and complications involving renal injury. Drug rash with eosinophilia and systemic symptoms (DRESS) syndrome is a severe, drug-induced hypersensitivity reaction characterized by skin rash, fever, lymph-node enlargement, and internal organ involvement. We describe a 22-year-old male who presented with acute kidney injury and was diagnosed with prolonged cholestatic hepatitis A. The patient also developed DRESS syndrome due to antibiotic and/or antiviral treatment. To our knowledge, this is the first report of histopathologically confirmed DRESS syndrome due to antibiotic and/or antiviral treatment following HAV infection with cholestatic features and renal injury.

Serial Testing of T-SPOT.TB Assays with Anti-Tuberculosis Therapy in Patients with Extrapulmonay Tuberculosis

BACKGROUND: Limited data are available for the clinical utility of serial interferon-gamma producing T-cell response after initiation of treatment in patients with extrapulmonary tuberculosis (TB). We studied the serial TB-specific antigen T-cell responses measured using the T-SPOT.TB assay during the course of therapy. MATERIALS AND METHODS: We prospectively enrolled adult patients who were newly diagnosed with active extrapulmonary TB over a 24-month period. All patients were given standard anti-TB treatment. Blood samples were obtained for T-SPOT.TB at diagnosis, as well as 1-, 3-, 6-, and 12-months after initiating anti-TB therapy. RESULTS: A total of 52 patients with extrapulmonary TB (38 confirmed and 14 probable TB) were included in the final analysis. All patients had clinical and radiologic improvement after treatment and cured. T-SPOT.TB was positive for 90% at diagnosis, 100% at 1-, 3-, and 6-months, and 93% at 12-months after initiation of anti-TB therapy. There was no significant difference in median T-cell response between early secreting antigenic target-6 (ESAT-6) and culture filtrate protein-10 (CFP-10) at all time points. Median T-cell response steadily increased up to 6 months and then decreased. CONCLUSIONS: T-SPOT.TB assay remained positive after successful anti-TB treatment in most patients with extrapulmonary TB. Our data suggests that serial T-SPOT.TB has limited clinical utility as a surrogate marker of treatment response in patients with extrapulmonary TB.

A Case of Acute Eosinophilic Pneumonia after Hematopoietic Stem Cell Transplantation / 결핵및호흡기질환

Pulmonary complications occur in 40~60% of patients who receive hematopoietic stem cell transplantation (HSCT) and are a source of substantial morbidity and mortality. Acute eosinophilic pneumonia (AEP) is an uncommon, non-infectious pulmonary complication occurring in HSCT recipients. We now report the case of a 52-year-old man with AEP who was treated with allogenic HSCT due to acute myeloid leukemia. He complained of fever, cough and dyspnea 390 days after allogenic HSCT. He also had skin and hepatic graft versus host disease (GVHD). Hypoxemia, diffuse pulmonary infiltrates on a chest x-ray and eosinophilia in bronchoalveolar lavage fluid were also noted in several tests. His symptoms, pulmonary infiltrates, hepatic dysfunction and skin lesions rapidly improved after treatment with corticosteroid therapy. Our case supports the idea that AEP is a late phase non-infectious pulmonary complication and one of the manifestations of chronic GVHD.
