ABSTRACT

Background@#The morphology of hair regrowth in alopecia areata (AA) patches could be classified into four types, namely diffuse, irregular, marginal, and targetoid patterns, according to the DIMT classification. However, factors affecting hair regrowth patterns have not been investigated. @*Objective@#We investigated whether the DIMT-classified hair regrowth patterns of AA patches are associated with treatment modality and patch size. @*Methods@#We conducted a retrospective, cross-sectional study of 152 AA patches with hair regrowth. @*Results@#The associations between the diffuse pattern and patch size >2 cm (p=0.006;odds ratio [OR]: 0.36, 95% confidence interval [CI]: 0.17~0.74), between the irregular pattern and triamcinolone acetonide intralesional injection (p2 cm (p=0.028; OR: 2.50, 95% CI: 1.10~5.68) were statistically significant. @*Conclusion@#Treatment modalities and patch size are the factors affecting hair regrowth patterns in AA patches.

ABSTRACT

Background/Aims@#Delayed diagnosis and treatment of smear-negative pulmonary tuberculosis (TB) are major concerns for TB control. We evaluated characteristics of patients with smear-negative pulmonary TB who received a delayed diagnosis and identified risk factors that may have contributed to this delay. @*Methods@#We reviewed medical records of patients with smear-negative culture-positive pulmonary TB treated at a tertiary care hospital in South Korea between January 2017 and December 2018. Patients who initiated anti-TB treatment after positive cultures were included in the missed TB group, and those who initiated empirical treatment before positive cultures were included in the control group. @*Results@#Of 220 patients included, 117 (53.2%) and 103 (46.8%) were in the missed TB and control groups, respectively. Patients in the missed TB group were older (p = 0.001) and had a higher mean body mass index (BMI) (p = 0.019). Comorbidities (66.9% vs. 46.6%, p = 0.003) and immunocompromised patients (33.1% vs. 20.4%, p = 0.035) were more common in the missed TB group than in the control group. Old age (odds ratio [OR], 1.030; 95% confidence interval [CI], 1.012 to 1.048; p = 0.001), high BMI (OR, 1.114; 95% CI, 1.004 to 1.237; p = 0.042), and negative polymerase chain reaction (PCR) results (OR, 9.551; 95% CI, 4.925 to 18.521; p < 0.001) were associated with delayed diagnosis. @*Conclusions@#In more than half of patients with smear-negative pulmonary TB, the diagnosis was delayed. Patients with delayed TB diagnosis were older, had higher BMI, and negative PCR results.

ABSTRACT

Background@#Increasing numbers of individuals are getting tattoos in recent times; however, the possible adverse effects of tattoos performed by non-medical practitioners are often overlooked. Limited information is available regarding the actual numbers of individuals getting tattoos and the perception regarding tattoos in the general population. @*Objective@#We investigated the prevalence of tattoos and public perception of tattoos. @*Methods@#Between August and September 2019, we performed a questionnaire survey that included 1,000 individuals aged ≥20 years. @*Results@#Among the 1,000 participants in this survey, 370 (37%) had received a tattoo; the number of participants with cosmetic tattoos (68.4%) was nearly 2-fold higher than the number of participants with body tattoos (31.6%). The most common motivation for getting a tattoo was “for beauty” (44.9%), followed by “convenience of make-up” (34.1%), and “recommendation from friends or others” (14.6%). In the tattoo-related satisfaction category, information regarding injected dye-induced adverse effects, facility hygiene, and pre-allergy testing were commonly rated as unsatisfactory by respondents. Only 322 (32.2%) participants were aware that semi-permanent tattoos could not be erased. Furthermore, 780 (78.0%) participants had a negative impression regarding body tattoos, and 844 (84.4%) participants preferred to get tattoos at specialized medical institutions based on the national regulations to minimize possible tattoo-induced adverse effects. @*Conclusion@#This study confirmed that a relatively large number of individuals had received tattoos but had a negative impression regarding this procedure. Educational and institutional management for public safety are necessary owing to a lack of awareness regarding tattoos and tattoo-related safety.

ABSTRACT

Lung cancer is the leading cause of cancer-related deaths in developing to advanced countries worldwide. The incidence rate of lung cancer in Korea has been increasing steadily since 1997. Statistics show that in 2017 alone, the incidence and mortality rates for lung cancer were 52.7 and 34.8 per 100,000 people, respectively, accounting for the highest cause of cancer death in Korea. The process of accurately diagnosing lung cancer consists of several steps, starting with the discovery of pulmonary nodule(s) via a cancer screening test or various other methods followed by the collection of cells or tissues and the identification of target molecules. Thereafter, staging and the development of a therapeutic plan lead to improved clinical outcomes. After the completion of a pilot study, a nationwide lung cancer screening program was introduced in Korea; since 2019, this program has targeted population at high risk for lung cancer: men and women aged 54 to 74 years who had a smoking history of 30 pack-years or more. The frequency of detection of pulmonary nodules is increasing in proportion to the public interest in health and economic growth.In this review, we present diagnostic techniques and biomarkers that are widely used in the medical field in the hope that such information would benefit clinical practice.

ABSTRACT

Background@#There are no data on comparison between clopidogrel monotherapy and prolonged dual antiplatelet therapy (DAPT) in patients at high-risk undergoing percutaneous coronary intervention (PCI). @*Methods@#Of 2,082 consecutive patients undergoing PCI using second-generation drugeluting stent (DES), we studied 637 patients at high-risk either angiographically or clinically who received clopidogrel longer than 24 months and were event-free at 12 months after index PCI. Patients were divided into 2 groups: the clopidogrel monotherapy group and the prolonged DAPT group. The primary outcome was a composite of all-cause death, non-fatal myocardial infarction (MI), definite or probable stent thrombosis, or stroke between 12 months and 36 months after the index PCI. @*Results@#In propensity score-matched population (246 pairs), the cumulative rate of primary outcome was 4.5% in the clopidogrel monotherapy group and 4.9% in the prolonged DAPT group (hazard ratio, 1.21; 95% confidence interval, 0.54–2.75; P = 0.643). There was no significant difference in all-cause death, MI, stent thrombosis, stroke between the clopidogrel monotherapy group and the prolonged DAPT group. @*Conclusion@#Compared with prolonged DAPT, clopidogrel monotherapy showed similar long-term outcomes in patients at high-risk after second-generation DES implantation.

ABSTRACT

Purpose@#We aimed to determine the relationship between environmental exposure and nontuberculous mycobacterial pulmonary disease (NTM-PD) in Korea. @*Materials and Methods@#A group of 150 patients with NTM-PD and a control group of 217 patients with other respiratory diseases were prospectively enrolled between June 2018 and December 2020 in Seoul, Korea. They were surveyed with a standardized questionnaire, and their medical records were reviewed. Odds ratio (OR) and 95% confidence intervals (CI) were calculated with multivariate logistic regression analysis. @*Results@#The mean ages of the NTM-PD and control groups were similar (63.8±9.2 years vs. 63.5±10.0 years; p=0.737), and most patients were female (76.0% vs. 68.7%; p=0.157) and nonsmokers (82.0% vs. 72.8%; p=0.021). Mycobacterium avium (49.3%) was the most commonly identified strain among NTM-PD patients, followed by M. intracellulare (32.0%) and M. abscessus subspecies massiliense (12.7%). There were no differences in housing type or frequency of soil- or pet-related exposure between the case and the control groups. However, in subgroup analysis excluding patients with M. intracellulare infection, more case patients frequently visited public baths ≥1 time/week (35.3% vs. 19.4%, p=0.003); this remained significant after multivariate analysis (OR, 2.84; 95% CI, 1.58–5.17). @*Conclusion@#Frequent exposure to water at public baths might affect the odds of contracting NTM-PD, excluding individuals infected with M. intracellulare strains.

ABSTRACT

Background@#In pityriasis versicolor, systemic antifungal agents may be indicated for widespread or refractory lesions rather than topical treatment. Oral ketoconazole is an effective treatment for pityriasis versicolor. To our knowledge, this is the first meta-analysis to compare antifungal agents one-to-one. @*Objective@#To compare the effectiveness of oral azole antifungal agents (fluconazole, itraconazole, and ketoconazole) one-to-one in pityriasis versicolor. @*Methods@#A computerized search was performed in different databases, including PubMed, Cochrane, EMBASE, OVID Medline, KoreaMed, KISS, and MedRIC. Seven randomized controlled trials were included. Further, statistical analyses of the extracted outcome data from the studies were performed using Rex Software (ver. 3.0.1). @*Results@#A total of 1,828 records were identified. The results of the meta-analysis including seven studies revealed no significant differences in the mycological cure rates between fluconazole and ketoconazole (risk ratio [RR]: 1.01, 95% confidence interval [CI]: 0.93∼1.09, p=0.8246), fluconazole and itraconazole (RR: 1.14, 95% CI: 0.81∼1.60, p=0.4512), and ketoconazole and itraconazole (RR: 1.07, 95% CI: 0.96∼1.20, p=0.2265). @*Conclusion@#There was no superiority in the therapeutic effect of any drug among the oral azole antifungals used in pityriasis versicolor.

ABSTRACT

Microcephalic osteodysplastic primordial dwarfism type II (MOPD II) is an autosomal recessive inherited disorder form of primordial dwarfism, caused by mutations in the pericentrin gene. The purpose of the study was to examine the clinical and radiological features, physicochemical properties and microstructures of the tooth affected with MOPD II.The mandibular 2nd molar was collected from the MOPD II patient. Micro-computerized tomography, scanning electron microscopy, energy dispersive spectrometry and Vickers microhardness analysis were performed on the MOPD II and the normal control.The morphology of the MOPD II tooth appeared to have malformed pulp and root and showed a small size. The mineral density measurement showed that the MOPD II tooth had similar scores in the enamel, but lower scores in the root 1/2 and apical dentin compared to the normal control. The microhardness values were smaller in the cusp enamel, root 1/2 dentin and apical dentin of the MOPD II compared to the normal control.In this study, the dental characteristics and the physicochemical properties of a tooth affected with MOPD II were analyzed to improve understanding of the oral manifestations of the disease and to assist in proper dental treatment by identifying precautions.

ABSTRACT

The purpose of this study was to investigate the three-dimensional characteristics of mesiodens using Cone-beam Computed Tomography(CBCT) and analyze the factors affecting complications and anesthetic methods of extraction. This study evaluated 602 mesiodens of 452 patients who underwent extraction of mesiodens at the department of Pediatric Dentistry in Seoul National University Dental Hospital between 2017 and 2019.The ratio of mesiodens patients over total patient per year was gradually increased over the past 20 years. Mesiodens with labio-palatally horizontal direction while root directing labial were the most common among the mesiodens with horizontal direction. Mesiodens were the most common at the cervical side of the adjacent teeth(37.0%) and mesiodens located in the near-palatal side were observed about 3.83 times higher than the far-palatal side. Most of the mesiodens(82.1%) were in contact with adjacent permanent teeth on all three sides of the CBCT and 46.2% of mesiodens had curved roots. The patient’s age, vertical position, presence of complications, and proximity showed a significant difference in the selection of general anesthesia among anesthetic methods. The direction and vertical position of mesiodens had a significant effect on complications.These results provide a better understanding of mesiodens for establishing an accurate diagnosis and treatment plan.

ABSTRACT

Background/Aims@#Fever is a common symptom of acute pancreatitis (AP). This study examined the factors associated with fever due to pancreatic inflammation in the early stages of non-biliary AP. @*Methods@#This study analyzed the AP database from Kangwon National University Hospital from January 2018 until April 2021 and identified patients who developed fever within 1 week of hospitalization. Patients with gallstone pancreatitis, pseudocyst, walled-off necrosis, chronic pancreatitis, bacteremia, and other site infections were excluded. The febrile group was compared with the afebrile group. @*Results@#One hundred and fifty-two patients were analyzed, and fever was diagnosed in 79 patients (52.0%). Based on multivariate analysis, fever was positively correlated with hypertriglyceridemia-induced AP (OR 16.8, 95% CI 4.0-70.7, p<0.01) and computed tomography severity index (OR 1.7, 95% CI 1.2-2.6, p<0.01). Recurrent AP was negatively associated with fever (OR 0.3, 95% CI 0.1-0.8, p=0.01). Fever was more frequent in patients with higher initial serum triglyceride (TG) levels than those with lower levels (TG <200 mg/dL; 35.1%, 200≤TG<500 mg/dL; 42.3%, TG ≥500 mg/dL; 88.6%, p<0.01). @*Conclusions@#Hypertriglyceridemia and CT severity index are associated with fever in early non-biliary AP.

ABSTRACT

@#Background & Objective: Mirror therapy has been shown to be effective in restoring upper extremity function in stroke patients through changes in the central nervous system. Therefore, it is important to evaluate the effectiveness of various tasks to induce central nervous system excitation. This study investigated the effect of using a complex task with multi-joint-based mirror therapy on upper extremity function and activities of daily living (ADL) in patients with hemiplegia after a stroke. Methods: In this study, 25 stroke patients were recruited and assigned randomly to the experimental or control group. The experimental group received a complex task using multi-joint-based mirror therapy, and the control group received a simple task using single-joint-based mirror therapy. Both groups received the same standard rehabilitation treatment 5 days per week for 4 weeks. An upper extremity evaluation was performed using the Fugl-Meyer Assessment (FMA) and Motor Activity log (MAL). The FMA includes an upper extremity subsection (FMA-UE) as well as upper arm (FMA-UA) and wrist/hand (FMA-WH) subparts. The MAL includes quality of movement (QOM) and amount of use (AOU) subsections. ADL were evaluated using the Korean version of the Modified Barthel Index (K-MBI). Results: Compared with the control group, the experimental group showed greater improvement on the FMA-UE, -UA, and -WH (p = 0.034, 0.047, and 0.013, respectively); MAL-AOU and -QOM (p = 0.048 and 0.034, respectively); and K-MBI (p = 0.031). The following effect sizes (Cohen’s d) were observed: FMA-UE, -UA, and -WH (1.0); MAL-AOU (0.2); MAL-QOM (1.6); and K-MBI (0.2). Conclusions: This study demonstrates that a complex task using multi-joint-based mirror therapy is more effective in restoring upper limb function and ADL in stroke patients than simple task-based mirror therapy.

ABSTRACT

BACKGROUND@#Although current guidelines recommend noninvasive stress tests prior to elective percutaneous coronary intervention (PCI), it is unknown whether antecedent exercise stress test (EST) affects the outcomes of patients undergoing PCI for stable ischemic heart disease (SIHD). This study aimed to investigate long-term outcomes in patients undergoing elective PCI with or without EST.@*METHODS@#We studied 2,674 patients undergoing elective PCI using drug-eluting stents for SIHD. Patients were divided into the 2 groups: the test group underwent EST with a positive result within 180 days prior to PCI (n = 668), whereas the non-test group did not undergo any noninvasive stress tests (n = 2,006). The primary outcome was all-cause death or myocardial infarction (MI).@*RESULTS@#Over 5 years after the index PCI, the risk of all-cause death or MI was significantly lower in the test group than in the non-test group in overall population (3.3% vs. 10.9%; adjusted hazard ratio [HR], 0.34; 95% confidence interval [CI], 0.22–0.55; P < 0.001), and in propensity score-matched population (668 pairs) (3.3% vs. 6.3%; adjusted HR, 0.52; 95% CI, 0.30–0.89; P = 0.018). However, the incidence of any revascularization was similar between the 2 groups in overall (16.7% vs. 16.8%; adjusted HR, 0.99; 95% CI, 0.79–1.25; P = 0.962) and matched population (16.7% vs. 18.3%; adjusted HR, 0.91; 95% CI, 0.70–1.19; P = 0.509).@*CONCLUSION@#Patients who underwent elective PCI with EST had a reduced risk of all-cause death or MI than those undergoing PCI without stress tests.

ABSTRACT

Background@#This study was performed to evaluate the effect of gastric cancer screening through analysis of screening-related data. @*Methods@#We investigated claims data of gastric cancer from 2009 to 2015. We evaluated whether the screening was performed to prior to registration as patients with gastric cancer. The effect of gastric cancer screening was also analyzed by gender. @*Results@#We collected total 196,293 patients with gastric cancer. 74% of them had previous experience of gastric cancer screening. In patients with screening, early gastric cancer was 33.4% and advanced gastric cancer was 17.3%. 22,548 (15.5%) patients were diagnosed with gastric cancer within 2 years after screening. In the case of patients without screening, early gastric cancer was 15.1% and advanced gastric cancer was 25.3%. In case of men, 76% of them confirmed gastric cancer through screening, and 70.2% of women confirmed the gastric cancer. In both men and women, the rate of early gastric cancer was higher among those with screening than those without screening. @*Conclusion@#In this study, we were able to indirectly confirm the stage shift of gastric cancer screening. However, within 2 years after screening, not a few patients with gastric cancer were diagnosed. Therefore, more studies are warranted to in the future.

ABSTRACT

BACKGROUND@#Mannitol increases blood–brain barrier permeability and can improve the efficiency of systemically administered stem cells by facilitating stem cell entry from the periphery into the injured brain. The aim of this study was to elucidate the neuroprotective effects of a combination of mannitol pretreatment and stem cell transplantation on strokeinduced neural injury. @*METHODS@#The experimental rats were randomly assigned to three groups 24 h after middle cerebral artery occlusion and reperfusion. One group received intravenous (IV) injections of phosphate-buffered saline (vehicle), another group received IV injections of human adipose-derived stem cells (hADSCs), and the last group received IV injections of hADSCs 10 min after IV mannitol injections. Neurobehavioral functions and infarct volume were compared. Immunohistochemistry (IHC) analyses were performed using antibodies against ionized calcium binding adapter-1 (IBA-1), rat endothelial antigen-1 (RECA-1), and bromodeoxyuridine/doublecortin (BrdU/DCX). @*RESULTS@#PKH-26 labeling revealed no difference in the number of stem cells that had migrated into the injured brain, and hADSC transplantation did not improve the infarct volume. However, neurobehavioral functions improved in the mannitol group. IHC showed higher numbers of RECA-1-positive cells in the peri-infarcted brain and BrdU-/DCXcolocalized cells in the subventricular zone in the mannitol group. IBA-1-positive cell number decreased in the hADSConly and mannitol-pretreatment groups compared with the vehicle group even though there was no difference between the former two groups. @*CONCLUSION@#Combinatorial treatment with mannitol and hADSC transplantation may have better therapeutic potential than hADSC monotherapy for ischemic stroke.

ABSTRACT

Interstitial cells of Cajal (ICC) are known as the pacemaker cells of gastrointestinal tract, and it has been reported that acute gastroenteritis induces intestinal dysmotility through antibody to vinculin, a cytoskeletal protein in gut, resulting in small intestinal bacterial overgrowth, so that anti-vinculin antibody can be used as a biomarker for irritable bowel syndrome. This study aimed to determine correlation between serum anti-vinculin antibody and ICC density in human stomach. Gastric specimens from 45 patients with gastric cancer who received gastric surgery at Kangwon National University Hospital from 2013 to 2017 were used. ICC in inner circular muscle, and myenteric plexus were counted. Corresponding patient's blood samples were used to determine the amount of anti-vinculin antibody by enzyme-linked immunosorbent assay. Analysis was done to determine correlation between anti-vinculin antibody and ICC numbers. Patients with elevated anti-vinculin antibody titer (above median value) had significantly lower number of ICC in inner circular muscle (71.0 vs. 240.5, p = 0.047), and myenteric plexus (12.0 vs. 68.5, p < 0.01) compared to patients with lower anti-vinculin antibody titer. Level of serum anti-vinculin antibody correlated significantly with density of ICC in myenteric plexus (r = −0.379, p = 0.01; Spearman correlation). Increased level of circulating anti-vinculin antibody was significantly correlated with decreased density of ICC in myenteric plexus of human stomach.

ABSTRACT

Objective@#This study aimed to investigate the clinicopathologic risk factors for type-specific persistence of high-risk human papillomavirus (hrHPV) and residual/recurrent cervical intraepithelial neoplasia (CIN) after surgical treatment. @*Methods@#Patients with CIN-2/3 who underwent conization or loop electrosurgical excision procedure (LEEP) at Korea University Hospital were enrolled. All patients underwent hrHPV testing and genotyping before conization or LEEP followed by both hrHPV genotyping and cytology. The significance of associations between patient characteristics and persistence of infection were assessed by multivariate logistic regression analyses. @*Results@#Among 398 women with pathologically confirmed CIN-2/3, 154 (38.7%) patients showed hrHPV persistence after surgical treatment. In multivariate analysis, high preoperative hrHPV load (P<0.05; odds ratio [OR], 2.063), presence of CIN-2 at treatment (P<0.01; OR, 2.732), and multiple hrHPV infections (P<0.001; OR, 4.752) were associated with hrHPV persistence. HPV 53 was the most likely to persist after treatment (24/43, 55.8%). The risk of residual/recurrent CIN-2/3 was higher in persistent infection with HPV 16 than other types (P<0.05). Menopause (P<0.001; OR, 3.969), preoperative and postoperative hrHPV load (P<0.05; OR, 2.430; P<0.05; OR, 5.351), and infection with multiple hrHPV types (P<0.05; OR, 2.345) were significantly related to residual/recurrent CIN following surgical treatment. @*Conclusion@#HPV load before treatment and infection with multiple hrHPV types were predictors of postoperative hrHPV persistence. HPV 53 was the type most likely to persist, but HPV 16 was the type that was most closely associated with residual/recurrent CIN-2/3.
