ABSTRACT
Background/Aims@#Although endoscopic ultrasound (EUS)-guided fine needle aspiration (FNA) and fine needle biopsy (FNB) are widely used for tissue acquisition of pancreatic solid mass, the optimal strategy of this procedure has not been established yet. The aim of this nationwide study was to investigate the current practice patterns of EUS-FNA/FNB for pancreatic solid mass in Korea. @*Methods@#The Policy-Quality Management of the Korean Pancreatobiliary Association (KPBA) developed a questionnaire containing 22 questions. An electronic survey consisting of the questionnaire was distributed by e-mail to members registered to the KPBA. @*Results@#A total of 101 respondents completed the survey. Eighty respondents (79.2%) performed preoperative EUS-FNA/FNB for operable pancreatic solid mass. Acquire needles (60.4%) were used the most, followed by ProCore needles (47.5%). In terms of need size, most respondents (>80%) preferred 22-gauge needles regardless of the location of the mass. Negative suction with a 10-mL syringe (71.3%) as sampling technique was followed by stylet slow-pull (41.6%). More than three needle passes for EUS-FNA/FNB was performed by most respondents (>80%). The frequency of requiring repeated procedure was significantly higher in respondents with a low individual volume (<5 per month, p=0.001). Prophylactic antibiotics were routinely used in 39 respondents (38.6%); rapid on-site pathologic evaluation was used in 6.1%. @*Conclusions@#According to this survey, practices of EUS-FNA/FNB for pancreatic solid mass varied substantially, some of which differed considerably from the recommendations present in existing guidelines. These results suggest that the development of evidence-based quality guidelines fitting Korean clinical practice is needed to establish the optimal strategy for this procedure.
ABSTRACT
Background/Aims@#Tegoprazan, a novel potassium-competitive acid blocker, has shown rapid action and gastric acid inhibition. In this study, we evaluated the efficacy of a tegoprazan-based, nonbismuth-containing quadruple (concomitant) therapy for the primary eradication of Helicobacter pylori. @*Methods@#We conducted a prospective, single-arm, single-center, primitive study to verify the efficacy of a 10-day tegoprazan- based (50-mg dose) concomitant therapy, including amoxicillin (1,000-mg dose), clarithromycin (CLA; 500-mg dose), and metronidazole (MET; 500-mg dose) twice daily as a first-line treatment for H. pylori eradication. @*Results@#We tested consecutive cultures for antibiotic susceptibility and minimum inhibitory concentrations. We enrolled 84 participants; 79 (94.0%) completed first-line therapy. The overall intention-to-treat and per-protocol eradication rates were 90.5% (95% confidence interval [CI], 82.1−95.8) and 96.2% (95% CI, 83.4–97.6), respectively. Of the 73 participants evaluated for antibiotic resistance, 19 (26.0%), 32 (42.5%), and 8 (11.0%) exhibited CLA, MET, and CLA and MET dual resistance, respectively. Of these, 39 participants (66.1%) exhibited successful eradication after the therapeutic regimen despite antibiotic resistance. @*Conclusions@#The 10-day tegoprazan-based concomitant therapy may be an effective first-line treatment for eradicating H. pylori.
ABSTRACT
Objective@#Venom-induced coagulopathy (VIC) is a common snakebite complication that can cause life-threatening hemorrhage. Previous studies have shown that snake venom can cause a decrease in the erythrocyte sedimentation rate (ESR), but this has not been investigated in actual clinical practice. This study evaluated the clinical utility of erythrocyte sedimentation rate as a predictive factor for VIC in patients with a poisonous snakebite. @*Methods@#From January 2012 to December 2021, this study performed a retrospective study of patients with venomous snakebites presenting to a tertiary emergency department. The demographic and laboratory data were collected through a chart review. The patients were divided into two groups, VIC and NoVIC groups. Logistic regression analysis was performed to identify the factors that predicted the presence of VIC, and the receiver operating characteristic (ROC) curve was drawn. @*Results@#One hundred and fifty-three patients were enrolled, and 31 patients (20.3%) developed VIC. The VIC group had significantly lower ESR than the NoVIC group (5.1±5.6 vs. 14.8±13.8; P<0.001). Logistic regression analysis showed that the decreased ESR was associated with the occurrence of coagulopathy (odds ratio, 0.957; 95% confidence interval, 0.917-0.999; P=0.045). The area under the curve was 0.701 in the ROC curve, and the cutoff value was set to 4.5 mm/hr. @*Conclusion@#ESR measured upon arrival at the emergency department was available to predict venom-induced coagulopathy in snakebite patients.
ABSTRACT
Background/Aims@#This study aimed to investigate the patterns of preferred endoscopic procedure types and techniques for managing difficult common bile duct (CBD) stones in South Korea. @*Methods@#The Committee of Policy and Quality Management of Korean Pancreatobiliary Association (KPBA) conducted a survey containing 19 questions. Both paper and online surveys were carried out; with the paper survey being conducted during the 2019 Annual Congress of KPBA and the online survey being conducted through Google Forms from April 2020 to February 2021. @*Results@#The response rate was approximately 41.3% (86/208). Sixty-two (73.0%) worked at tertiary hospitals or academic medical centers, and 60 (69.7%) had more than 5 years of endoscopic retrograde cholangiopancreatography experience. The preferred size criteria for large CBD stones were 15 mm (40.6%), 20 mm (31.3%), and 30 mm (4.6%). For managing of large CBD stones, endoscopic papillary large balloon dilation after endoscopic sphincterotomy was the most preferred technique (74.4%). When performing procedures in those with bleeding diathesis, 64 (74.4%) respondents favored endoscopic papillary balloon dilation (EPBD) alone or EPBD with small endoscopic sphincterotomy. Fifty-five respondents (63.9%) preferred the doubleguidewire technique when faced with difficult bile duct cannulation in patients with periampullary diverticulum. In surgically altered anatomies, cap-fitted forward viewing endoscopy (76.7%) and percutaneous transhepatic cholangioscopy (48.8%) were the preferred techniques for Billroth-II anastomosis and total gastrectomy with Roux-en-Y anastomosis, respectively. @*Conclusions@#Most respondents showed unifying trends for the management of difficult CBD stones. The current practice patterns could be used as basic data for clinical quality improvements in the management of difficult CBD stones.
ABSTRACT
Purpose@#We investigated the current status of imaging studies for pediatric blunt cervical spine injury, and applied 3 clinical decision rules to children with blunt trauma of the head or neck in a pediatric emergency center in Korea. The rules included National Emergency X-Radiography Utilization Study (NEXUS) criteria, Canadian Cervical Spine Rule, and Pediatric Emergency Care Applied Research Network risk factors. @*Methods@#This was a retrospective study conducted on 399 children aged 15 years or younger who visited the center after the blunt trauma, and underwent cervical spine radiographs from January 2020 through December 2021. We examined the clinical characteristics per age groups (0-1, 2-5, 6-12, and 13-15 years). Using the 3 rules, we selected children with a potential need for imaging studies (PNI). For this purpose, we analyzed the absence of low-risk variables and the presence of high-risk variables. Predictive performances of the rules were measured for the imaging-confirmed cervical spine injury. @*Results@#The study population (n = 399) had a median age of 5.0 years (interquartile range, 2.0-9.0) and a 64.2% boys’ proportion. Fall (36.6%) was the most common injury mechanism. Two children had the cervical spine injuries. As per NEXUS criteria, Canadian Cervical Spine Rule, and Pediatric Emergency Care Applied Research Network risk factors, 72 (18.0%), 289 (72.4%), and 74 children (18.5%) were classified as those with PNI, respectively. Resultantly, 291 children (72.9%) were classified as having PNI whereas the other 108 (27.1%) were deemed to undergo unnecessary imaging. The 3 rules had nearly 100% sensitivity and negative predictive value, except a 50% sensitivity of NEXUS criteria. @*Conclusion@#Imaging studies can be minimized for children with blunt trauma of the head or neck who are deemed without PNI per the 3 current clinical decision rules. More elaborate criteria are needed to make a timely diagnosis.
ABSTRACT
Objective@#After the coronavirus disease 2019 (COVID-19) outbreak, there have been some changes in the way the medical system deals with suspected infectious diseases. These changes may also affect non-COVID-19 patients. Acute appendicitis is a common disease that requires emergent surgical intervention in pediatric patients, and delayed diagnosis and treatment may cause some complications. This study analyzed the impact of the COVID-19 pandemic on the incidence of complicated appendicitis in pediatric patients presenting to emergency departments in South Korea. @*Methods@#The target group (post-COVID group) included patients aged under 15 years and diagnosed with acute appendicitis between February 23 and November 30, 2020. Patients diagnosed during the same period in 2019 were selected as the control group (pre-COVID group). The difference in the incidence of complicated appendicitis before and after the COVID-19 outbreak was investigated, and the association with various variables was analyzed using the odds ratios and 95% confidence intervals. @*Results@#The study enrolled a total of 94 patients: 54 in the pre-COVID group and 40 in the post-COVID group. There was no statistically significant variation in the incidence of complicated appendicitis (31.5% vs 35.0%, P=0.723) between the groups. In-hospital time was longer in the post-COVID group (7 hours vs. 10.5 hours, P=0.014), but pre-hospital time showed no significant difference (16 hours vs. 22 hours, P=0.768). In the multivariable logistic regression analysis, pre-hospital time (odds ratio [OR], 1.08; P=0.004), erythrocyte sedimentation rate (OR, 33.24; P<0.001), and the presence of fever (OR, 21.11, P=0.002) showed a significant correlation. @*Conclusion@#Post the COVID-19 pandemic outbreak, there was no difference in the incidence of pediatric complicated appendicitis in South Korea.
ABSTRACT
Background/Aims@#Endoscopic ultrasonography (EUS) provides high-resolution images and is superior to computed tomography (CT) scan in diagnosing small pancreatic ductal adenocarcinoma (PDAC). As a result, the use of EUS for early detection of PDAC has attracted attention. This study aimed to identify the clinical and radiological characteristics of patients with PDAC diagnosed by EUS but not found on CT scan. @*Methods@#The medical records of patients diagnosed with PDAC at 12 tertiary referral centers in Korea from January 2003 to April 2019 were reviewed. This study included patients with pancreatic masses not clearly observed on CT scan but identified on EUS. The clinical characteristics and radiological features of the patients were analyzed, and survival analysis was performed. @*Results@#A total of 83 patients were enrolled. The most common abnormal CT findings other than a definite mass was pancreatic duct dilatation, which was identified in 61 patients (73.5%). All but four patients underwent surgery. The final pathologic stages were as follows: IA (n=31, 39.2%), IB (n=8, 10.1%), IIA (n=20, 25.3%), IIB (n=17, 21.5%), III (n=2, 2.5%), and IV (n=1, 1.4%). The 5-year survival rate of these patients was 50.6% (95% confidence interval, 38.8% to 66.7%). Elevated liver function testing and R1 resection emerged as significant predictors of mortality in the multivariable Cox regression analysis. @*Conclusions@#This multicenter study demonstrated favorable long-term prognosis in patients with PDAC diagnosed by EUS but indeterminate on CT scan. EUS should be considered for patients with suspected PDAC but indeterminate on CT scan.
ABSTRACT
Background/Aims@#The study aimed to investigate the current practice patterns in the management of pancreatic cystic neoplasms in Korea. @*Methods@#An electronic survey was systematically distributed by email to members of the Korean Pancreatobiliary Association from December 2019 to February 2020. @*Results@#In total, 115 (110 gastroenterologists, five surgeons) completed the survey, 72.2% of whom worked in a tertiary/academic medical center. Most (65.2%) followed the 2012/2017 International Association of Pancreatology guidelines for the management of pancreatic cystic neoplasms. A gadolinium-enhanced magnetic resonance imaging/magnetic resonance cholangiopancreatography was the most common first-line diagnostic modality (42.1%), but a contrast-enhanced computed tomography scan was preferred as a subsequent surveillance tool (58.3%). Seventy- four percent of respondents routinely performed endoscopic ultrasound-guided fine needle aspiration for pancreatic cystic neoplasms with suspicious mural nodules. Endoscopic ultrasound-guided fine needle aspiration cytology (94.8%) and cystic fluid carcinoembryonic antigen (95.7%) were used for cystic fluid analysis. Most (94%) typically recommended surgery in patients with high-risk stigmata, but 18.3% also considered proceeding with surgery in patients with worrisome features. Most (96.5%) would continue surveillance of pancreatic cystic neoplasms for more than 5 years. @*Conclusions@#According to this survey, there was variability in the management of pancreatic cystic neoplasms among the respondents. These results suggest that the development of evidence-based guidelines for pancreatic cystic neoplasms that fit the Korean practice is needed to create an optimal approach to the management of pancreatic cystic neoplasms.
ABSTRACT
Background and Objectives@#This study compares Vocal Fatigue Index (VFI) scores according to the presence or absence of external laryngeal tension in hyperfunctional voice disorder. And through this, it is to confirm the usefulness of VFI to hypertension of extrinsic laryngeal muscles.Materials and Method The subjects were 61 female diagnosed with hyperfunctional voice disorder (hypertension group 41, non-hypertension group 20). The author palpated extrinsic laryngeal muscles for evaluation of hypertension and classified them as the presence or absence. The voice measurements were jitter, shimmer, Korean-Voice Handicap Index-10 (K-VHI-10), and Korean-Vocal Fatigue Index (K-VFI). The voice compared were according to the diagnosis and presence of hypertension only for patients with hyperfunctional voice disorder. @*Results@#As a result of comparing the voice measurement according to the presence or absence of hypertension, there was no significant difference in the acoustic variables, K-VHI-10 and K-VFI-Total, K-VFI-Fatigue. Whereas, K-VFI-Physical (p=0.006) and K-VFI-Rest (p=0.022) were significantly higher in the hypertension group. @*Conclusion@#These results indicate that the hypertension group has more physical discomfort and less voice recovery than the group without hypertension. It means that K-VFI can measure the physical discomfort and limitations of voice recovery due to hypertension of the external laryngeal muscle. The VFI can be used as one of the methods to evaluate the hypertension of the external laryngeal muscle in Hyperfunctional voice disorder.
ABSTRACT
Objective@#Although accurate diagnosis in neurologic emergencies is critical, the emergency department (ED) suffers from a shortage of neurologists. The purpose of this study was to investigate the effect of a dedicated neurologist on the competence in the management of ED physicians on patients with neurologic abnormalities. @*Methods@#We retrospectively reviewed the medical records of patients with neurologic abnormalities between 1 March 2016 and 30 September 2019. Two periods, including control and intervention periods, were assigned. Neurology consultations were routinely performed by an ED physician in the control period and by a physician of the ED working with a dedicated neurologist in the intervention period. @*Results@#In the control period, the most frequent chief complaints were dizziness (22.45%), focal motor weakness (except the face, 19.62%), altered mental status (9.98%), dysarthria (9.62%), seizures (8.57%), and headaches (6.87%). In the intervention period, the rate of final disposition by the ED physician was significantly increased in patients with dizziness (P<0.001), altered mental status (P=0.003), dysarthria (P<0.001), seizure (P<0.001), headaches (P<0.001), facial palsy (P<0.001), and memory impairment (P=0.043). @*Conclusion@#ED physicians who were educated by a dedicated neurologist could effectively enhance the competence in the management of the patient with neurologic abnormalities. We suggest that the method implemented in this study can be a good alternative for solving the gap in neurology department consultation.
ABSTRACT
Objective@#This study aimed to evaluate the effectiveness of the CRB-65 score as a prognostic predictor in acute heart failure (HF) patients who visited the emergency department (ED). @*Methods@#This study was performed retrospectively on HF patients over the age of 19 years admitted to the ED between August 2018 and July 2020. The patients who met the Framingham criteria, including acute pulmonary edema, were classified by the CRB-65 score and compared with previous HF prognostic predictors (Acute Decompensated Heart Failure National Registry, Get with The Guidelines-Heart Failure and Enhanced Feedback for Effective Cardiac Treatment). We defined the primary outcome as 30-day mortality and secondary outcomes as hospitalization days (HD), admission to intensive care unit (ICU), length of stay (LOS) in the ICU and mechanical ventilation (MV). We conducted linear regression and logistic regression with these outcomes and obtained the area under the receiver-operating characteristics (AUROC) curve to compare the predictive power of the primary outcome. @*Results@#A total of 462 patients were included in the study, and their mean age was 80 years. According to the linear and logistic regression analysis results, the CRB-65 score was significantly correlated with HD (P<0.001), admission to ICU (P=0.014), LOS in ICU (P<0.001) and MV (P=0.004). The AUROC curve of CRB-65 was not higher than the other previous prognostic predictors (AUROC, 0.69), but the result was not different from the predictors. @*Conclusion@#The CRB-65 score is one of the prognostic indicators of acute HF in the ED. However, its prognostic predictive power remains limited.
ABSTRACT
Background/Aims@#The work environment in which endoscopic retrograde cholangiopancreatography (ERCP) is conducted has influence on its efficacy and safety. We aimed to assess the current status of ERCP work environments and to investigate the trends associated with the basic techniques of ERCP in Korea. @*Methods@#The work environment and information on the basic techniques of ERCP were acquired by the Korean Pancreatobiliary Association (KPBA) through a national survey in 2019. The survey was performed at the KPBA conference in 2019. The contents of survey comprised of the current environment of ERCP, preparation before ERCP, and the preferred basic techniques used in ERCP. @*Results@#Completed questionnaires were returned from 84 KPBA members. The mean ERCP volume per year was approximately 500. About 60% (50/84) reported that they worked with a dedicated ERCP team with experienced nurses. Two-thirds (57/84, 68%) answered that they had a fluoroscopy room used solely for ERCP procedures. All respondents intravenously hydrated the patient to prevent post-ERCP pancreatitis (84/84, 100%). The preferred procedural sedations were balanced propofol sedation (50%) and midazolam-only sedation (47%). Wire-guided cannulation was most commonly used for selective cannulation (81%). Endoscopic retrograde biliary drainage was preferred over endoscopic nasobiliary drainage (60% vs 22%). The initial method of ampullary intervention was endoscopic sphincterotomy in 60%. @*Conclusions@#Data from the survey involving a large number of Korean ERCP doctors revealed considerable variabilities with regard to the work environment and basic techniques of ERCP in Korea. The study provides information regarding the current trends of ERCP that can be used to establish ERCP standards in Korea.
ABSTRACT
Background@#This study investigated the longitudinal associations between the degrees of positive and negative spillover in work–life balance (WLB) at baseline and reports of depressive mood at a 2-year follow-up in Korean women employees. @*Methods@#We used a panel study design data of 1386 women employees who participated in the Korean Longitudinal Survey of Women and Families in both 2014 and 2016. Depressive mood was measured using the “10-item Center for Epidemiologic Studies Depression Scale.” Associations between the positive and negative spillover in WLB at baseline and reports of new incidence of depressive mood at 2-year follow-up were explored using a multivariate logistic regression model. @*Results@#Negative spillover in WLB at baseline showed a significant linear association with reports of depressive mood at 2-yearfollow-up after adjusting for age, education level, marital status, number of children, and positive spillover (P = 0.014). The highest scoring group in negative spillover (fourth quartile) showed a significant higher odds ratio of 1.95 compared with the lowest scoring group (first quartile; P = 0.036). @*Conclusion@#Positive spillover in WLB showed a U-shaped association with depression. The degrees of positive and negative spillover in WLB among Korean women employees at baseline were associated with new incidence of depressive mood within 2 years. To prevent depression of female workers, more discrete and differentiated policies on how to maintain healthy WLB are required.
ABSTRACT
Objective@#The current study examined the differential empathic capacity, post-traumatic symptoms, and coping strategies in healthcare workers (HCWs) according to the exposure of verbal or physical workplace violence (WPV). @*Methods@#Using online survey, a total of 422 HCWs employed at a training general hospital of South Korea participated and completed self-reporting questionnaires including the WPV questionnaire with coping strategy, the Jefferson Scale of Physician Empathy. @*Results@#Those who experienced either only verbal violence or both physical and verbal violence had lower Jefferson Scale of Physician Empathy scores (p<0.05). Posttraumatic stress symptom severity was higher among people who experienced verbal violence than physical violence. HCWs’ exposure to verbal violence was associated with severe posttraumatic symptoms and a low level of empathy with patients (p<0.05). More than half of the victims of verbal violence responded that they did not take any action, receive organizational protection, or peer support, while most physically-abused HCWs received institutional intervention or help from others. @*Conclusion@#Our findings highlight the critical importance of reducing verbal violence, which may represent a larger psychological burden compared to physical violence, by actively implementing effective strategies and policies at the institutional level.
ABSTRACT
To date, there is no standardization of the endoscopi c retrograde cholangiopancreatography (ERCP) room setting regarding with the size, equipment or space arrangement. Therefore, the authors visited 11 tertiary hospitals that recently remodeled or newly designed the ERCP room to analyze and identify their advantages and disadvantages. The ERCP room should have enough space for equipments including fluoroscopy, endoscopy, electrosurgical unit, preparation table and for patient movement. The EUS room does not require an independent space unless it is a very large scale hospital, and the ERCP room can be shared. Considering the pros and cons of each equipment, adequate fluoroscopic device should be selected depending on the hospital circumstance. Expensive equipment for X-ray fluoroscopy system is not necessarily good, and it is necessary to install equipment suitable for each hospital situation by understanding the advantages and disadvantages of fluoroscopy. For prevention of ERCP-related radiation hazard, both endoscopist and assistants should wear radiation-blocking apron, thyroid protectors, and lead glasses. Furthermore, a shield that can block radiation between the endoscopist and the patient should be installed to protect high-energy scattered waves. One-way direction should be designed to prevent cross infection when moving the endoscopic equipment from the ERCP to the cleaning room. If possible, it is recommended to keep a cardiopulmonary resuscitation cart in the ERCP room.
ABSTRACT
Objective@#Triage in the emergency department is important as mistriage leads to inefficient use of resources. The Korean Triage and Acuity Scale (KTAS) was developed in 2012 and has been implemented in emergency departments nationwide since January 2016. The purpose of this study was to determine whether KTAS can predict resource use in a pediatric emergency center. @*Methods@#From October to December 2019, a retrospective analysis was conducted by a review of medical records. Demographic data, KTAS grades, Emergency Severity Index (ESI) as an indicator of resource utilization and details of the use of each resource were collected. Patients were divided into non-trauma and trauma groups. KTAS grades 1 and 2 were defined as the severe group, grade 3 was the moderate group, and grades 4 and 5 were defined as the mild group. We investigated whether triage using KTAS is related to resource utilization. @*Results@#In the non-trauma group, ESI, length of stay in the emergency department, and hospitalization were significantly correlated with the KTAS groups. In the trauma group, there was no significant difference between the moderate and mild groups in the above variables except for hospitalization. This was because there was no significant difference in sedation, procedure, and intravenous injection, in the trauma group. @*Conclusion@#The KTAS triage helped predict resource utilization in the non-trauma group, but not in the trauma group especially between the moderate and mild groups. Additional research will be needed to predict resource utilization in children with trauma.
ABSTRACT
Background/Aims@#Recently, the European Society of Gastrointestinal Endoscopy (ESGE) proposed criteria for “difficult biliary cannulation” during endoscopic retrograde cholangiopancreatography (ERCP). This study aimed to investigate the clinical relevance of the ESGE criteria from the perspective of post-ERCP pancreatitis (PEP). @*Methods@#An ERCP database was prospectively maintained between November 2014 and December 2015 across six teaching hospitals in South Korea. The ESGE criteria (biliary cannulation time, the number of cannulation attempts, and inadvertent pancreatic duct [PD] manipulation) were recorded in this database as well as other technical factors. Logistic regression analysis was used to identify risk factors for PEP. Then, the PEP prediction model was investigated using decision tree analysis. @*Results@#We analyzed 1,067 consecutive patients with naïve papilla. The overall rate of PEP was 6.6%. Multivariate analysis revealed that female sex (odds ratio [OR], 1.860; 95% confidence interval [CI], 1.124 to 3.078), a selective biliary cannulation duration >5 minutes (OR, 3.282; 95% CI, 1.641 to 6.566), and inadvertent PD manipulation (OR, 2.614; 95% CI, 1.480 to 4.617) were significant factors affecting PEP. Decision tree analysis revealed that biliary cannulation time (χ2 =49.857, p5 minutes, and >5 minutes with inadvertent PD manipulation, respectively. @*Conclusions@#Biliary cannulation time and inadvertent PD manipulation could be relevant indicators of PEP, and 5 minutes might be used as a cutoff value for the implementation of the rescue cannulation technique.
ABSTRACT
Background@#This study aimed to assess the effects of iodine intake, thyroid function, and their combined effect on the risk of papillary thyroid cancer (PTC) and papillary thyroid microcarcinoma (PTMC). @*Methods@#A case-control study was conducted including 500 community-based controls who had undergone a health check-up, and 446 overall PTC cases (209 PTC and 237 PTMC) from the Thyroid Cancer Longitudinal Study. Urinary iodine concentration (UIC), was used as an indicator of iodine intake, and serum for thyroid function. The risk of PTC and PTMC was estimated using unconditional logistic regression. @*Results@#Excessive iodine intake (UIC ≥220 μg/gCr) was associated with both PTC (odds ratio [OR], 18.13 95% confidence interval [CI], 8.87 to 37.04) and PTMC (OR, 8.02; 95% CI, 4.64 to 13.87), compared to adequate iodine intake (UIC, 85 to 219 μg/gCr). Free thyroxine (T4) levels ≥1.25 ng/dL were associated with PTC (OR, 1.97; 95% CI, 1.36 to 2.87) and PTMC (OR, 2.98; 95% CI, 2.01 to 4.41), compared to free T4 levels of 0.7 to 1.24 ng/dL. Individuals with excessive iodine intake and high free T4 levels had a greatly increased OR of PTC (OR, 43.48; 95% CI, 12.63 to 149.62), and PTMC (OR, 26.96; 95% CI, 10.26 to 70.89), compared to individuals with adequate iodine intake and low free T4 levels. @*Conclusion@#Excessive iodine intake using creatinine-adjusted UIC and high free T4 levels may have a synergistic effect on PTC and PTMC. Considering both iodine intake and thyroid function is important to assess PTC and PTMC risk.
