The Health Status and Management of Migrant Workers in Cheonan:A Comparison Study With Korean Citizens

Migrant workers face challenging working conditions, resulting in physical and mental vulnerability. The objective is to identify their health vulnerabilities and ensure their right to health. Health records of 163 migrant workers (113 males and 50 females) (Group A) and 163 Korean citizens (Group B) visiting our institution were analyzed from August 2021 to July 2022. Both groups underwent urine analysis, chest radiography, and various blood tests. Statistical analysis using independent t-tests and χ2 tests was performed. Group A had a significantly higher rate of hepatitis B virus surface antigen-positive patients, lower vaccination rates for hepatitis B, and poorer nutritional status compared to Group B. Group B generally exhibited higher levels of albumin, glucose, total cholesterol, and thyroidstimulating hormone. There were significant quantitative differences in multiple blood cell and hemoglobin measurements between the two groups. These findings emphasize the need for policy support and public awareness to protect the health rights of migrant workers.

Comparison of Visceral Adiposity Index and Chinese Visceral Adiposity Index for Coronary Artery Calcification in Korean Adults

BACKGROUND: Visceral adiposity index (VAI) was developed to estimate visceral fat, and its association with various diseases including cardiovascular disease, insulin resistance, and fatty liver has been revealed. The Chinese VAI (CVAI) has been newly developed in China. This study aimed to compare the VAI and CVAI for coronary artery calcification by using the coronary artery calcium score (CACs)-a predictable index of asymptomatic atherosclerosis.METHODS: We conducted a cross-sectional study that included 66,011 participants (76.3% male and 23.7% female participants) visiting an university hospital for medical check-ups between January 2014 and December 2016. A receiver operating characteristic curve analysis was performed and the area under the curve (AUC) was calculated to compare the concordance of the CACs and the VAI, CVAI, waist circumference, body mass index, triglycerides, and high-density lipoprotein cholesterol.RESULTS: In all participants, the AUC for the CVAI was the largest, while that for the VAI was fourth among all the indices (AUC(CVAI)=0.653, AUC(VAI)=0.592). The AUC for the CVAI was the largest among the indices in both sexes (female AUC(CVAI)=0.77, male AUC(CVAI)=0.592), while that for the VAI was the second largest (female, AUC(CVAI) 0.771>AUC(VAI) 0.651; male, AUC(CVAI) 0.592>AUC(VAI) 0.564).CONCLUSION: In conclusion, the CVAI showed a higher degree of concordance with CACs, which is an indirect indicator of cardiovascular disease, than the VAI in Korean adults.

Characteristics and Outcomes of Septoplasty in Patients with Paradoxical Nasal Obstruction / 대한이비인후과학회지

BACKGROUND AND OBJECTIVES: The aim of this study was to evaluate clinical characteristics and outcome of septoplasty in patients complaining of paradoxical nasal obstruction. SUBJECTS AND METHOD: Medical records of 637 patients who underwent septoplasty from 2011 to 2016 were reviewed retrospectively. One hundred sixty-nine patients whose follow up periods were longer than 3 months were included. These patients were categorized into two groups, the experimental group (paradoxical nasal obstruction) and the control group. We analyzed the degree of nasal obstruction, the sino-nasal outcome test (SNOT)-22 score, which is the sino-nasal outcome, and the minimal cross-sectional area in acoustic rhinometry. The effect of concurrent turbinoplasty was also evaluated. RESULTS: Paradoxical nasal obstruction was found in 19 patients (11.2%). Compared to the control group, the degree of mucosal change (both concave and convex side) had no statistical significance. Although the degree of nasal obstruction and SNOT-22 scores were significantly improved after surgery in both groups (p<0.05), the values for the experimental group were slightly increased at 3 months of surgery after having been improved at one month of surgery. In contrast, those values improved steadily over time in the control group. The tendency of psychologic domain scores was significantly different between the two groups (p=0.021). The results of volume reductive turbinoplasty showed that it maintained the improved symptoms better when performed along with septoplasty. CONCLUSION: Although septoplasty showed beneficial effects in patients with paradoxical nasal obstruction, the effect of septoplasty decreased over time. Concurrent volume reductive turbinate surgery maintained the effect of septoplasty in paradoxical nasal obstruction.

Long-Term Outcome of Endoscopic Sinus Surgery in Patients with Aspirin-Exacerbated Respiratory Disease / 대한이비인후과학회지

BACKGROUND AND OBJECTIVES: Patients with aspirin-exacerbated respiratory disease (AERD) tend to have more severe clinical course and also tend to be recalcitrant to conventional medical and surgical treatment. This study aimed to assess the long-term outcome of endoscopic sinus surgery in AERD patients. SUBJECTS AND METHOD: Fifteen patients with AERD (n=15) were identified through a retro-spective chart review, and compared with 74 patients of CRSwNP (with asthma n=23; without asthma n=51) by analyzing preoperative and postoperative symptoms, endoscopic score, Lund-Mackay CT score, number of revision surgery or outpatient procedures, frequency of clinic visits and medications. The CRS control status was evaluated according to the European Position Paper on Rhinosinusitis and Nasal Polyps 2012 criteria and logistic regression analyses were conducted to investigate the determining factors of preoperative and postoperative symptoms. RESULTS: The AERD group showed higher disease severity than other groups preoperatively: endoscopic score (CRSwNP s asthma 6.3±2.6 vs. CRSwNP c asthma 6.5±2.3 vs. AERD 8.8±1.4, p<0.05), CT score (12.2±4.9 vs. 17.0±4.8 vs. 18.0±2.1, p<0.05), and overall symptom score (30.8±0.4 vs. 33.8±1.5 vs. 37.9±0.7, p<0.01). The rate of revision surgery and outpatient procedures, postoperative clinic visit and prescription rate were higher in the AERD group (p<0.05, respectively). However, postoperative symptom scores and CRS control status were not significantly different among three groups (p=0.267 and p=0.996, respectively). CONCLUSION: Although AERD patients showed higher preoperative endoscopic scores and revision surgery rates, postoperative subjective symptoms were comparable to those of other groups with long-term follow up, suggesting the importance of frequent outpatient care after endoscopic sinus surgery.

The Impact of Allergic Rhinitis on Symptom Improvement in Pediatric Patients After Adenotonsillectomy

OBJECTIVES: It is well known that allergic rhinitis (AR) has positive association with adenotonsillectomy. However, the impact of AR on symptom improvement after adenotonsillectomy is not well documented. Hence, we aimed to evaluate the effect of AR on the symptom improvement after adenotonsillectomy between AR and nonallergic patients. METHODS: A retrospective analysis was performed on 250 pediatric patients younger than 10 years old who received adenotonsillectomy from June 2009 to June 2014 in a tertiary referral hospital. All patients underwent skin prick test or multiple allergen simultaneous test (MAST) before surgery and classified into AR group and control group. Obstructive and rhinitis symptoms including snoring, mouth breathing, nasal obstruction, rhinorrhea, itching, and sneezing were evaluated before and 1 year after surgery using questionnaire and telephone survey. RESULTS: AR group was 131 and control group was 119, showing higher prevalence (52.4%) of AR among adenotonsillectomized patients. Both groups showed dramatic improvement of symptoms such as snoring and mouth breathing after surgery (all P < 0.05). However, AR group showed significantly less improvement than control group in snoring, mouth breathing, nasal obstruction, and rhinorrhea (all P < 0.05). Multivariate analysis showed that preoperative mouth breathing and snoring were dependent on tonsil grade and postoperative symptoms were mainly dependent on presence of AR. Nasal obstruction was dependent on tonsil grade and presence of AR preoperatively and presence of AR postoperatively. These suggest the importance of AR as a risk factor for mouth breathing, snoring, and nasal obstruction. CONCLUSION: AR has positive association with adenotonsillectomy and not only allergic symptoms but also obstructive symptoms such as snoring and mouth breathing improved less in AR group than control group. Hence, patients with AR should be monitored for long-term basis and more carefully after adenotonsillectomy.

Focal Hepatic Eosinophilic Infiltration in Contrast-Enhanced Ultrasonography with Sonazoid: A Case Report

Focal eosinophilic infiltration in the liver is often associated with various eosinophil-related conditions. Focal eosinophilic infiltration in the liver is often identified incidentally by radiologic examinations ordered for other reasons, and is usually visualized radiographically as small, ill-defined, oval or round nodules. Focal eosinophilic infiltration in the liver may sometimes mimic hepatic metastases in those patients who present with a history of malignancy. Here, we present two cases of contrast enhanced ultrasonography findings of focal hepatic eosinophilic infiltration using Sonazoid (perfluorobutane; Daiichi-Sankyo, GE, Tokyo, Japan).

A Case of Fibromyxoma of the Maxilla

Fibromyxoma is a rare mesenchymal tumor that is benign, but locally invasive. It is a slow-glowing painless tumor with the potential for extensile bony destruction and cortical expansion and shows a relatively high recurrence rate. Fibromyxoma is found predominantly in the jaw, with the mandible more frequently affected than the maxilla. We recently experienced a case of fibromyxoma originating from the maxilla in a 50-year-old woman who complained of swelling on the right side of her cheek. En bloc resection via a sublabial approach and middle meatal antrostomy were performed. A diagnosis of fibromyxoma was based on pathologic findings. No recurrence or locally residual lesion has been found during 2-years follow up. Therefore, we present this rare case with a review of the literature.

The Prenatal and Postnatal Incidence of Congenital Anomalies of the Kidneys and Urinary Tract (CAKUT) Detected by Ultrasound

PURPOSE: Congenital anomalies of the kidneys and urinary tract (CAKUT) are the most common anomalies identified in newborns. This study aims to demonstrate the prevalence of CAKUT including hydronephrosis diagnosed by antenatal and postnatal ultrasound over a five-year period. METHODS: The records of births between May 1st, 2009 and April 30th, 2014 at our hospital were collected. The number of infants who underwent renal ultrasound after birth for the detection of CAKUT was counted. The incidence of each type of CAKUT such as hydronephrosis, size abnormality, horseshoe kidney, and Multicystic dysplastic kidney (MCDK) was retrospectively evaluated for antenatal screening and postnatal follow-up examination. RESULTS: During the study period, 33,276 infants were born and 521 neonates underwent postnatal renal ultrasound. 183 cases of CAKUT were detected prenatally and 140 postnatally using ultrasonographic examinations at the following time: (i) 3-7 days postnatally in 123 newborns (87.9%), (ii) during 1-3 months in 11 newborns (7.9%), and (iii) later than 3 months in 6 newborns (4.3%). Among diagnosed CAKUT, hydronephrosis was the most common anomaly with 113 newborns diagnosed prenatally and 46 postnatally. Duplex kidney was the second most common anomaly followed by horseshoe kidney, simple cysts in the kidney and so on. CONCLUSION: The detection of CAKUT is an important part of the prenatal ultrasound. This study analyzed the prevalence of CAKUT detected on prenatal screening and compared the results to those detected postnatally. Prenatal ultrasound screening fulfills the needs of postnatal examinations and therefore, both antenatal and postnatal sonographic investigations are of vital importance for diagnosis of renal and urinary tract anomalies.

Clinical Significance of Epidural Hematoma Related to Birth in Newborn / 대한주산의학회잡지

PURPOSE: Epidural hematoma (EDH) in newborn is very rare, but when it occurs it is usually due to birth injury. We have evaluated the incidence and clinical features of EDH related to birth in newborn. METHODS: We analyzed medical records of 12 newborns diagnosed with EDH at Cheil General Hospital and Women's Health Care Center from January 2000 to December 2015 retrospectively. RESULTS: The incidence of EDH related to birth was 0.01%, occurring in 1 of 10,000 live births. Of the total 12 cases, 10 occurred in male and 8 in vaginal delivery. Among them, 11 infants had evidences of birth injury. Clinical presentation was nonspecific: only 1 infant had neurologic symptoms. The temporooccipital area was the most frequent location of EDH. The median size of EDH was 3.2±0.8 cm in length and 1.2±0.7 cm in depth. Mass effect accompanied with midline shift on radiologic imaging was shown in one case. Surgical drainage was needed only in one infant with neurologic symptom and mass effect on radiologic imaging, while the others were treated conservatively. CONCLUSION: Neonatal EDH related to birth was treated conservatively in most cases. The radiologic mass effect and neurologic symptom should be considered as indication for surgical intervention.

A Case of Huge Lingual Tonsillar Hypertrophy Causing Obstructive Sleep Apnea in Adult

Obstructive sleep apnea is characterized by repeated episodes of obstructive apnea and hypopnea. Lingual tonsillar hypertrophy causing obstructive symptoms is a rare disease in adults. Recently, we experienced a case of obstructive sleep apnea due to massive lingual tonsillar hypertrophy. The patient had tonsillectomy as a child and underwent adenoidectomy three years prior to the current presentation due to snoring and sleep apnea. However, symptoms did not improve and were recently aggravated. The upper airway evaluation and polysomnography revealed excessive lingual tonsillar hypertrophy and severe obstructive sleep apnea. An enlarged lingual tonsil was successfully removed using a Coblator. No recurrence was observed, and the obstructive sleep apnea was resolved postoperatively.

Cholecystectomy for Prevention of Recurrence after Endoscopic Clearance of Bile Duct Stones in Korea

PURPOSE: Cholecystectomy in patients with an intact gallbladder after endoscopic removal of stones from the common bile duct (CBD) remains controversial. We conducted a case-control study to determine the risk of recurrent CBD stones and the benefit of cholecystectomy for prevention of recurrence after endoscopic removal of stones from the CBD in Korean patients. MATERIALS AND METHODS: A total of 317 patients who underwent endoscopic CBD stone extraction between 2006 and 2012 were included. Possible risk factors for the recurrence of CBD stones including previous cholecystectomy history, bile duct diameter, stone size, number of stones, stone composition, and the presence of a periampullary diverticulum were analyzed. RESULTS: The mean duration of follow-up after CBD stone extraction was 25.4+/-22.0 months. A CBD diameter of 15 mm or larger [odds ratio (OR), 1.930; 95% confidence interval (CI), 1.098 to 3.391; p=0.022] and the presence of a periampullary diverticulum (OR, 1.859; 95% CI, 1.014 to 3.408; p=0.045) were independent predictive factors for CBD stone recurrence. Seventeen patients (26.6%) in the recurrence group underwent elective cholecystectomy soon after endoscopic extraction of CBD stones, compared to 88 (34.8%) in the non-recurrence group; the difference was not statistically significant (p=0.212). CONCLUSION: A CBD diameter of 15 mm or larger and the presence of a periampullary diverticulum were found to be potential predictive factors for recurrence after endoscopic extraction of CBD stones. Elective cholecystectomy after clearance of CBD stones did not reduce the incidence of recurrent CBD stones in Korean patients.

Clinical and Neuropsychological Characteristics of Adult Alcohol Use Disorder Patients with or without Attention-Deficit Hyperactivity Symptom

OBJECTIVES: Alcohol use disorder (AUD) is often comorbid with adult attention-deficit hyperactivity disorder (ADHD) and other psychiatric illnesses. When associated with other mental problems, the prognosis of the AUD can be more serious. This study shows research on the clinical and neuropsychological characteristics according to whether or not ADHD symptoms and AUD were comorbid. METHODS: MethodsA total of 64 adult inpatients who completed AUD scales about adult ADHD, alcohol dependence, depression, anxiety, and impulsiveness. They also completed neuropsychological tests about attention and executive function. According to the Adult ADHD Self-Report Scale score, patients were categorized into two groups (ADHD symptom positive/negative group). RESULTS: Fourteen among the 64 subjects were part of the ADHD symptom positive group (21.9%). They had statistically significant shorter abstinence periods and a higher rate of history of 'rule violation during school' and 'physical damage in childhood' compared to the ADHD symptom negative group. CONCLUSION: The comorbidity rate with ADHD symptom in adult AUD is higher than the general population. The ADHD symptom positive group suffered from more severe and refractory AUD. Considering the more frequent history of rule violation during school in the ADHD symptom positive group, the association between ADHD and AUD may be mediated by conduct disorder. Therefore we suggest the necessity of careful evaluation and intervention in children and adolescents with ADHD and conduct disorder.

A Delayed Hepatico-colonic Fistula after Radiofrequency Ablation in Hepatocellular Carcinoma / 대한내과학회지

Percutaneous radiofrequency thermal ablation (RFA) performed under ultrasound guidance is a safe, effective therapeutic modality for managing liver malignancies. Although surgical resection remains the treatment of choice for hepatocellular carcinoma (HCC), RFA has emerged as a reliable alternative. Potential complications of RFA include liver abscess, ascites, pleural effusion, skin burns, hypoxemia, pneumothorax, subcapsular hematoma, hemoperitoneum, liver failure, tumor seeding, and biliary lesions. Here, we report a rare complication after RFA for HCC: a delayed liver abscess and transverse colonic fistula. The patient was treated successfully with percutaneous abscess drainage, antibiotics, liver segmentectomy, and segmental resection of the fistula and involved colon. Due to its rarity, we report this case and review the literature.

The Effects of Overnight Orthokeratology Lens Wear on Ocular Scatter

PURPOSE: To evaluate the change of visual quality after wearing orthokeratology lenses overnight. METHODS: This study included 13 patients (24 eyes) who wore orthokeratology lenses for the first time. Visual quality was assessed with the optical quality analysis system (OQAS) using the double-pass technique. The value of modulation transfer function (MTF) cutoff, Strehl ratio, and objective scatter index (OSI) were measured at baseline and 4 weeks after wearing the lenses. RESULTS: The mean spherical equivalent decreased from -2.70 +/- 1.03 diopters (D) to 0.03 +/- 0.36 D after 4 weeks of wearing orthokeratology lenses and uncorrected visual acuity improved from log MAR 0.88 +/- 0.17 to log MAR 0.03 +/- 0.04. The MTF cutoff decreased from 38.20 +/- 11.01 to 34.79 +/- 10.30 and the Strehl ratio decreased from 0.24 +/- 0.07 to 0.21 +/- 0.07 but without statistical significance. The OSI significantly increased from 0.38 +/- 0.19 to 0.72 +/- 0.40 after wearing orthokeratology lenses. CONCLUSIONS: Orthokeratology lenses were effective for correction of myopia and astigmatism. The OSI increased after wearing the lenses, but MFT cutoff and Strehl ratios were not affected.

Objective Optical Quality Analysis in Dry Eye Syndrome

PURPOSE: To evaluate the efficacy of Optical Quality Analysis System (OQAS(R)) instrument for the assessment of dry eye syndrome. METHODS: Dynamic recording of double-pass (DP) retinal images was performed in 1 eye dry eye patients (20 eyes) and in healthy controls (20 eyes) for 20 seconds after eye blinking. RESULTS: The mean objective scatter Index (OSI) value was 4.53 in dry eyes, 0.67 in healthy eyes and the standard deviation of OSI was 1.20 in dry eyes and 1.18 in healthy eyes. The patients with dry eyes showed significantly higher mean OSI and standard deviation values. Ocular scatter increased over time and significant changes occurred 13.5 seconds after blinking. The difference in OSI value between 0 second and 20 seconds was significantly greater in dry eye patients (4.15) than in controls (0.32). CONCLUSIONS: Ocular scatter increased over time after blinking. The dry eye patients had larger and more variable ocular scatter index than the controls. OQAS(R) may be useful to detect and follow-up tear film-related patient complaints in dry eye syndrome.

Clinical Results and Optical Quality of Diffractive Multifocal IOL Implantation after Myopic Refractive Surgery

PURPOSE: To evaluate the visual outcome and optical quality in eyes with diffractive multifocal intraocular lens (DMIOL) implantation after myopic refractive surgery. METHODS: Nineteen eyes (15 patients) were implanted with AcriSof ReSTOR(R) SN6AD1, the aspheric DMIOL after myopic refractive surgery (laser-assisted in situ keratomileusis [LASIK] 14 eyes, photorefractive keratectomy [PRK] 4 eyes, laser-assisted subepithelial keratomileusis [LASEK] 1 eye). Preoperative and postoperative visual acuities and manifest refraction were measured. Preoperative corneal higher-order aberrations (HOAs) were measured using Hartmann-Shack (H-S) aberrometer in dilated pupils, and optical qualities were measured 1 month postoperatively using H-S aberrometer and a double-pass system under mesopic conditions. Patient satisfaction was investigated using a questionnaire at 2 months postoperatively. RESULTS: Uncorrected distant and near visual acuities at postoperative 2 months were 0.11 +/- 0.19, and 0.19 +/- 0.12 (log MAR), respectively. Postoperative spherical equivalent (SE) of 16 eyes (84.2%) was within +/-0.50 diopters (D) and all eyes were within +/-1.00 D from emmetropia. Preoperative corneal and postoperative ocular spherical aberrations in a 4.0 mm pupil diameter were 0.08 +/- 0.08 and 0.07 +/- 0.07 (microm), respectively. Objective scatter index was 3.42 +/- 1.71 and modulation transfer function (MTF) cut-off value was 21.03 +/- 12.37 cpd. General satisfaction score was 3.52 +/- 0.96 points out of 5, and 8 patients (11 eyes) were not satisfied with DMIOL implantation. CONCLUSIONS: After DMIOL implantation in the eyes with previous myopic refractive surgery, postoperative SE was close to the target D, but optical qualities and patient satisfaction were poor.

CONCLUSIONS: After DMIOL implantation in the eyes with previous myopic refractive surgery, postoperative SE was close to the target D, but optical qualities and patient satisfaction were poor.

Comparison of Continuous Curvilinear Capsulorhexis Parameters between Femtosecond Laser and Conventional Cataract Surgery

PURPOSE: To compare parameters of femtosecond laser and manual continuous curvilinear capsulorhexis (CCC) using anterior segment optical coherence tomography (AS-OCT). METHODS: Femtosecond laser cataract surgery was performed in 30 eyes of 30 patients, and conventional cataract surgery with a manual CCC in 30 eyes of 30 patients. One month after surgery, CCC diameters, circularity of capsulotomy, and distance between the CCC and pupil center were analyzed using the AS-OCT. RESULTS: Mean maximal CCC diameter was 4.96 +/- 0.23 mm in the femtosecond laser group, and 4.70 +/- 0.82 mm in the manual CCC group. Mean minimal CCC diameter was 4.91 +/- 0.23 mm in the femtosecond group, and 4.48 +/- 0.64 mm in the manual CCC group showing significant difference between the two groups (p = 0.000). Circularity of capsulotomy was 0.99 +/- 0.01 in the femtosecond group and 0.91 +/- 0.13 in the manual CCC group and was statistically different between the 2 groups (p = 0.000). The distance from the CCC center to the pupil center was 0.18 +/- 0.09 mm in the femtosecond group and 0.26 +/- 0.17 mm in the manual CCC group. The CCC center was closer to the pupil center in the femtosecond than in the manual CCC group (p = 0.038). CONCLUSIONS: Properly sized and shaped capsulotomy can be expected in femtosecond laser CCC compared with manual CCC.
