ABSTRACT
Background@#Rosacea is a chronic inflammatory facial disorder, leading to impaired skin barrier function. Many factors, including skin care habits, affect its occurrence and progress. @*Objective@#This study aimed to investigate clinical manifestation and aggravating factors of rosacea, focusing on skin care habits and lifestyle and to compare them with those of acne patients. @*Methods@#We conducted a cross-sectional survey among 222 patients with rosacea and 127 with acne who visited a university hospital and local dermatologic clinic between July 2021 and June 2022. The patients answered questionnaires consisting of information, such as demographic characteristics, clinical symptoms and signs, skin care habits, and aggravating factors. @*Results@#Age distribution of the patients with rosacea showed a peak incidence among those in their twenties, and the most common comorbidity was metabolic disease. The most common symptom and sign was itching, followed by burning sensation. Regarding skin care habits, 72.8% and 45.0% of the patients practiced excessive cleansing and double cleansing, respectively. The most frequently-used cleanser and basic cosmetic were foaming cleanser (77.5%) and toner (57.5%), respectively. Foundation was used by nearly half of the woman, many of whom used liquid type.Irregular or insufficient sleep and food were the two most common aggravating factor. When compared to patients with acne patients, those with rosacea tended to carry more systemic comorbidities and practiced double cleansing with basic cosmetics more actively. @*Conclusion@#It is important for clinicians to understand various factors affecting occurrence and aggravation of rosacea and educate patients on appropriate skin care habits and lifestyle.
ABSTRACT
Background@#The aim of this study was to estimate the 8-year prevalence and mortality statistics of autism spectrum disorder (ASD) according to birth year (2002–2012). @*Methods@#We used the National Health Insurance Service database with 4,989,351 children born from 2002 to 2012 including 35,529 children diagnosed with ASD until 8 years of age.The 8-year cumulative prevalence of ASD was calculated annually (2010–2020) with 8 years of follow-up. The 8-year mortality was estimated using Cox models adjusted for sex, household income, area of residence, and year of birth. @*Results@#Of the 473,494 children born in 2002, 2,467 (5.2 per 1,000 births) were diagnosed with ASD until 2010. The ASD prevalence was 2.6 times higher among boys (1,839; 7.4 per 1,000 boy births) than girls (628; 2.8 per 1,000 girl births). Of the 467,360 children born in 2012, 4,378 (9.4 per 1,000 births) were diagnosed with ASD until 2020. The ASD prevalence was 2.7 times higher among boys (3,246; 13.5 per 1,000 boy births) than girls (1,132; 5.0 per 1,000 girl births). The risk of all-cause mortality was higher among children with ASD than those without (hazard ratio [HR], 2.340; 95% confidence interval [CI], 2.063–2.654), which is substantially higher among girls (HR, 4.223; 95% CI, 3.472–5.135) than boys (HR, 1.774; 95% CI, 1.505–2.090). @*Conclusion@#The present study demonstrated that national-level prevalence and mortality statistics of ASD can be estimated effectively using claims data comprising newborns born each year and followed up for to the age of interest. Because this information is essential to establish evidence-based policies, health authorities need to consider producing epidemiological information of ASD continuously using the same methodology.
ABSTRACT
Colonic angiosarcoma is an extremely rare and aggressive malignant tumor with poor prognosis. We report a case of colonic epithelioid angiosarcoma with colonic obstruction and rapidly progressive hepatic metastasis in a 44-year-old female. Abdominal CT revealed a heterogeneously enhancing irregular mass in the ascending colon, causing proximal bowel distension. The patient underwent surgery, and histopathological examination revealed a poorly differentiated carcinoma. A follow-up liver dynamic MRI after 4 months revealed newly developed diffusely scattered numerous small nodules in both hepatic lobes with peripheral and nodular marked arterial hyperenhancement, raising the suspicion of hepatic angiosarcoma. A pathologic second opinion was obtained, and additional immunohistochemistry revealed colonic epithelioid angiosarcoma. The patient showed progressive hepatic metastasis on follow-up abdominal CT after 6 months and died 8 months after initial diagnosis. We describe an educational case of colonic angiosarcoma, a rare malignant tumor, with rapidly progressive hepatic metastasis that showed radiologic findings suggestive of angiosarcoma and enabled a re-diagnosis for proper treatment and prognosis prediction.
ABSTRACT
Purpose@#The purpose of this study was to evaluate the anti-inflammatory effects of non-thermal atmospheric pressure plasma (NTP) on human gingival fibroblasts (HGFs) for clinical application of periodontal treatment. @*Materials and Methods@#HGFs were treated with Porphyromonas gingivalis (Pg) lipopolysaccharide (LPS). Customized NTP device was developed for periodontal in vitro study. Cell viability was evaluated with cell counting kit-8. The levels of inflammatory cytokines, including interleukin (IL)-8 and 6, were determined by enzyme-linked immunosorbent assay. @*Results@#When NTP was applied, the cell viability did not change significantly, and there was no difference for 6 h and 24h. When Pg LPS was treated to HGFs, the secretion of IL-8 and IL-6 was increased compared to the control group. But when the NTP was applied, the secretion of them was significantly decreased. @*Conclusion@#NTP did not affect cell viability of HGFs. And it inhibited the LPS-induced production of IL-8 and IL-6.
ABSTRACT
Purpose@#This study aimed to investigate the association between autism spectrum disorder (ASD) diagnosis and mortality among children using the data from a large-scale national cohort of Korean infants and children. We also explored the association between hearing impairment detected during early infancy and mortality. @*Materials and Methods@#We performed a retrospective cohort study using the nationwide claims data of the Republic of Korea.Children born between 2007 and 2014 (n=3598904) were followed up until 2020. Cox proportional hazard models were used to examine the association between ASD diagnosis and mortality among children. Then, in order to evaluate the association between hearing impairment and mortality, Cox proportional hazard models were built using the responses related to hearing impairment asked during the first health screening (at age 4–6 months). @*Results@#Of the 3598904 children born between 2007 and 2014, 32878 children (0.9%) were diagnosed with ASD until the end of 2020. We identified that ASD diagnosis was associated with higher mortality among children [hazard ratio (HR)=2.5, 95% confidence interval (CI): 2.2–2.9]. This association was stronger among girls (HR=4.8, 95% CI: 3.9–5.8) compared to boys (HR=1.9, 95% CI: 1.6–2.2). We found that hearing impairment detected during infancy was associated with higher mortality among children with ASD diagnosis. @*Conclusion@#ASD diagnosis was associated with higher mortality among Korean children. This association was stronger in girls than in boys. Hearing impairment detected during infancy was also associated with higher mortality among children diagnosed with ASD.
ABSTRACT
Fourteen African swine fever (ASF) outbreaks occurred in the pig farms in the northwestern region of South Korea, near the border with North Korea, from September 16, 2019 to October 9, 2019. Active and passive surveillance on the ASF-infected farms indicated that the infection was limited only to pigsties where the infected pigs were detected on the farm for the first time before further transmission to other pigsties and farms. This early detection could be one of the pivotal factors for the prompt eradication of ASF in domestic pig farms within 1 month in the northwestern region of South Korea.

ABSTRACT
Purpose@#This study aimed to evaluate the reproducibility and diagnostic performance of a quantitative parameter of superb microvascular imaging (SMI) in real-time breast ultrasonography (US) for differentiating benign from malignant breast masses. @*Methods@#Eighty-seven breast masses in 75 patients who underwent both B-mode US and SMI before US-guided core needle biopsy were included in this study. Two radiologists performed B-mode US and measured the vascular index (VI) of SMI respectively for each lesion in real time. Intraobserver and interobserver agreements were analyzed for the VI of SMI. The diagnostic performance of B-mode US using the Breast Imaging Reporting and Database System lexicon and combined use with the VI of SMI was evaluated compared to pathology. @*Results@#The median VI of malignant masses (n=32) was significantly higher than that of benign masses (n=55) (7.6% and 2.6%, respectively; P<0.001). The intraobserver agreement for VI was excellent regardless of the pathology, size, or depth of the lesion. The interobserver agreement for VI was excellent regardless of the presence of a measurement interval. The interobserver agreement for the final diagnostic decision was improved by combining B-mode US and VI (κ=0.883) in comparison with B-mode US only (κ=0.617). Adding VI led to significant improvements in the specificity (87.2% vs. 52.7%, 83.6% vs. 49.0%), accuracy (89.7% vs. 69.3%, 84.0% vs. 65.9%) and positive predictive value (81.5% vs. 55.1%, 75.6% vs. 52.6%) of B-mode US for both observers compared with B-mode US alone (all, P=0.001). @*Conclusion@#The VI of SMI for real-time breast US is highly reproducible and leads to improved diagnostic performance for differentiating between benign and malignant breast lesions in combination with B-mode US.
ABSTRACT
Purpose@#Immunization with Porphyromonas gingivalis heat shock protein 60 (PgHSP60) may have an immunoregulatory effect on atherogenesis. The aim of this study was to determine whether nasal immunization with a PgHSP60 peptide could reduce atherosclerotic plaque formation in apolipoprotein E knockout (ApoE KO) mice. @*Methods@#Seven-week-old male ApoE KO mice were assigned to receive a normal diet, a Western diet, a Western diet and challenge with PgHSP60-derived peptide 14 (Pep14) or peptide 19 (Pep19), or a Western diet and immunization with Pep14 or Pep19 before challenge with Pep14 or Pep19. @*Results@#Atherosclerotic plaques were significantly smaller in mice that received a Western diet with Pep14 nasal immunization than in mice that received a Western diet and no Pep14 immunization with or without Pep14 challenge. An immunoblot profile failed to detect serum reactivity to Pep14 in any of the study groups. Stimulation by either Pep14 or Pep19 strongly promoted the induction of CD4+CD25+forkhead box P3 (FoxP3)+ human regulatory T cells (Tregs) in vitro. However, the expression of mouse splenic CD4+CD25+FoxP3+ Tregs was lower in the Pep14-immunized mice than in the Pep14-challenged or Pep19-immunized mice. Levels of serum interferon gamma (IFN-γ) and transforming growth factor beta were higher and levels of interleukin (IL) 10 were lower in the Pep14-immunized mice than in the other groups. Induction of CD25− IL-17+ T helper 17 (Th17) cells was attenuated in the Pep14-immunized mice. @*Conclusions@#Nasal immunization with Pep14 may be a mechanism for attenuating atherogenesis by promoting the secretion of IFN-γ and/or suppressing Th17-mediated immunity.
ABSTRACT
To restore a tooth with a fracture line extending below the marginal bone level, a surgical crown lengthening procedure accompanied by ostectomy could be considered to expose the fracture line and reestablish the biologic width. However, this procedure could lead to esthetic failure, especially in the anterior teeth. Therefore, orthodontic extrusion, which elevates the fracture line from within the alveolar socket without sacrificing the supporting bone and gingiva, is recommended. This technique allows for the proper placement of the crown on a sound tooth structure, with the reestablishment of the biologic width.Alternatively, surgical extrusion is an one-step procedure that is simpler and less time-consuming than orthodontic extrusion; placing and adjusting the orthodontic appliance does not require multiple visits. This study presents successful restoration in 2 cases with a crown-tooth root fracture of the maxillary central incisor treated using a multidisciplinary approach through orthodontic extrusion or surgical extrusion followed by successful restoration.

ABSTRACT
High-flow nasal oxygenation (HFNO) is a promising new technique for anesthesiologists. The use of HFNO during the induction of anesthesia and during upper airway surgeries has been initiated, and its applications have been rapidly growing ever since. The advantages of this technique include its easy set-up, high tolerability, and its abilities to produce positive airway pressure and a high fraction of inspired oxygen and to influence the clearance of carbon dioxide to some extent. HFNO, via a nasal cannula, can provide oxygen both to patients who can breathe spontaneously and to those who are apneic; further, this technique does not interfere with bag-mask ventilation, attempts at laryngoscopy for tracheal intubation, and surgical procedures conducted in the airway. In this review, we describe the techniques associated with HFNO and the advantages and disadvantages of HFNO based on the current state of knowledge.
ABSTRACT
The mesentery is a structure comprising a double peritoneal layer that attaches the bowel to the abdominal wall. Mesenteric disease can cause various non-specific clinical symptoms in adults and is sometimes found incidentally during unrelated diagnostic imaging studies. CT plays an essential role in the diagnosis of mesenteric disease, which can present with various radiologic features, including a solid mass, cystic mass, or local or diffuse infiltration on CT. Some mesenteric diseases present with distinctive characteristics, while others share similar findings, thereby complicating their differential diagnosis. Therefore, understanding the radiological findings of mesenteric disease is important for accurate diagnosis and appropriate treatment.
ABSTRACT
In this case report, gingival recession of the mandibular anterior teeth was treated with a laterally closed tunnel technique. Two patients had altered the inclination of mandibular anterior tooth during past orthodontic treatment and had periodontal thin biotype. The recipient site was formed by tunneling method, and the connective tissue graft obtained from the palatal side was placed in the tunnel, and the margins of flap were gathered at the center of the root and sutured. Despite the thin periodontal biotype, the root coverage was successfully obtained, keratinized gingiva was increased, and aesthetics were achieved by harmonizing with surrounding tissues in terms of shape and color.
ABSTRACT
OBJECTIVE: To determine the prevalence of osteoporosis (OP) and osteoporotic vertebral fracture (OVF) in people with Parkinson’s disease (PD) in Korea and its association with socioeconomic status.METHODS: Using Health Insurance Review and Assessment Service-National Inpatient Sample (HIRA-NIS) data from 2009 to 2013, we estimated the annual prevalence of PD, OP, and OVF and investigated its association with socioeconomic status using data from National Health Insurance (NHI) beneficiaries and Medical Aid (MA) recipients. This study was supported by research funding from Korean Society for Bone and Mineral Research 2015. There were no study-specific biases related to conflicts of interest.RESULTS: The number of PD patients in the HIRA-NIS increased each year from 2009 to 2013. Among patients with PD, the standardized prevalence rates of OP and OVF increased from 2009 to 2013; from 23.2 to 27.8 and from 2.8 to 4.2, respectively. Among patients with PD with OP, the prevalence of OVF were 12.2% and 15.1% in 2009 and 2013, respectively. The standardized prevalence rates of PD with OP and PD with OVF were significantly higher in MA recipients than in NHI beneficiaries.CONCLUSION: The prevalence of PD both with OP and with OVF increased and the prevalence was higher in MA recipients than in NHI beneficiaries. These findings may suggest that age over 65 years, female and low income may be a significant factor related to PD occurring with OP and OVF.

PURPOSE: This study examined the prevalence and risk factors of peri-implant disease after at least 7 years of dental implant loading.METHODS: A total of 111 patients with 218 dental implants were treated. The follow-up period for all implants was at least 7 years. The patients' dental records were collected and risk factors of peri-implant disease were investigated through logistic regression analysis.RESULTS: The overall implant survival rate was 95.87%, because 9 of the 218 implants failed. The prevalence of peri-implant mucositis and peri-implantitis was 39.7% and 16.7%, respectively. As risk factors, smoking and prosthetic splinting showed significant associations with peri-implantitis (P&0.05).CONCLUSIONS: Within the limits of this study, no significant correlations were found between any risk factors and peri-implant mucositis, but a significantly elevated risk of peri-implantitis was observed in patients who smoked or had splinted prostheses in 2 or more implants.
