RESUMO

Idiopathic spontaneous intraperitoneal hemorrhage is both rare and potentially fatal. The incidence of gastroepiploic artery rupture, especially a non-aneurysmal rupture, is extremely low. We report the case of an elderly woman who was mistakenly diagnosed with procedure-related bleeding after gastroscopy. A 0.3 cm polyp was identified and removed during the procedure. The patient later developed shock due to which gastroscopy was repeated; however, no unusual findings were observed. Therefore, abdominopelvic computerized tomography was performed and gastroepiploic artery rupture was detected. Transcatheter arterial embolization was immediately performed without laparotomy, without any complications. The bleeding was controlled, and the patient was discharged after embolization. It is important to acknowledge the possibility of spontaneous rupture of the visceral arteries in elderly individuals with hypertension or atherosclerosis, especially in the event of sudden abdominal pain or shock immediately after an endoscopic procedure. This is the first case report of idiopathic spontaneous rupture of the right gastroepiploic artery successfully managed by transcatheter arterial embolization in South Korea.

RESUMO

The evaluation of occlusion using digital methods is easier and simpler in terms of recording, comparison, analysis, and objectivity compared to existing methods such as articulating paper and occlusion foil. The purpose of this case report was utilizing the digital method for evaluating occlusion. The occlusion of patient requiring full veneer crown restoration was evaluated using an intraoral scanner (i500, Medit, Seoul, Korea) at every visit. The occlusion was also assessed using conventional articulating paper and a digital occlusal analysis system (Dental prescale II, GC corp., Tokyo, Japan) for comparison. Throughout the treatment process, the intraoral scanner and the conventional articulating paper method showed similar outcomes. The results suggest that the use of digital evaluation system is highly probable in the near future.

RESUMO

Lower extremity deep vein thrombosis (DVT) is a serious medical condition that can result in local pain and gait disturbance. DVT progression can also lead to death or major disability as a result of pulmonary embolism, postthrombotic syndrome, or limb amputation. However, early thrombus removal can rapidly relieve symptoms and prevent disease progression. Various endovascular procedures have been developed in the recent years to treat DVT, and endovascular treatment has been established as one of the major therapeutic methods to treat lower extremity DVT. However, the treatment of lower extremity DVT varies according to the disease duration, location of affected vessels, and the presence of symptoms. This article reviews and discusses effective endovascular treatment methods for lower extremity DVT.

RESUMO

Background@#The adverse effects of particulate matter (PM) on the skin have been concerning recently. @*Objective@#We investigated PM induced inflammation on barrier-interrupted skin and relieving effects of plant extracts on PM-induced skin irritation. @*Methods@#A total of 20 participants were enrolled for the induction of skin irritation. Sodium lauryl sulfate (SLS) patch was affixed to the forearm for 24 hours. After patch removal, total suspended particulates (TSPs) were applied. After inducing skin irritation using SLS and TSP, cream containing 0.1% mixture of plant extracts (Citrus sunki, Sceptridium ternatum (Botrychium ternatum), and Korthalsella japonica) was applied. The a* value, erythema index (EI), and transepidermal water loss (TEWL) were measured. @*Results@#The a* value was significantly higher at the site where TSPs were applied than that at the site where TSPs were not applied at 1 and 2 days after SLS patch removal. The a* value, EI, and TEWL were significantly low in the cream-applied area 7 days after the introduction of the SLS patch and TSPs. @*Conclusion@#PM induced skin irritation in a previously disrupted skin barrier. Topical application of plant extracts alleviated skin irritation symptoms caused by dust exposure.

RESUMO

Purpose@#To evaluate the safety and efficacy of the percutaneous manual aspiration thrombectomy technique to treat thrombotic occlusion of native arteriovenous fistulas. @*Materials and Methods@#A retrospective review of 20 patients who underwent percutaneous manual aspiration thrombectomy for native thrombotic arteriovenous fistula occlusion from March 2012 to December 2017 was performed. We evaluated technical and clinical success rates and complications. The primary and secondary patency rates were calculated using the Kaplan-Meier analysis. @*Results@#Percutaneous manual aspiration thrombectomy was performed in 20 patients (n = 20) with concomitant balloon angioplasty. The overall technical and clinical success rates were both 85% (n = 17). The native arteriovenous fistulas, based on their site, were the left radiocephalic (n = 13), left brachiocephalic (n = 4), and right radiocephalic (n = 3) fistulas. An underlying stenosis was detected in the juxta-anastomotic venous site (n = 16), outflow draining vein (n = 12), and central vein (n = 4). The primary and secondary patency rates at 1, 3, 6, and 12 months were 100%, 70.6%, 70.6%, and 56.5% and 100%, 94.1%, 94.1%, and 86.9%, respectively. There were no complications associated with procedure. @*Conclusion@#Percutaneous manual aspiration thrombectomy is a safe and effective method to treat thrombotic native arteriovenous fistula occlusion.

RESUMO

BACKGROUND: Recently, the number of nationwide medical researches on psoriasis using the National Health Insurance Service database has been on the rise. However, identification of psoriasis using diagnostic codes alone can lead to misclassification. Accuracy of the diagnostic codes and their concordance with medical records should be validated first to identify psoriasis patients correctly.OBJECTIVE: To validate the diagnostic codes of psoriasis (International Classification of Diseases, 10th Revision L40) and to find the algorithm for the identification of psoriasis.METHODS: We collected medical records of patients who received their first diagnostic codes of psoriasis during 5 years from five hospitals. Fifteen percent of psoriasis patients were randomly selected from each hospital. We performed a validation by reviewing medical records and compared 5 algorithms to identify the best algorithm.RESULTS: Total of 538 cases were reviewed and classified as psoriasis (n=368), not psoriasis (n=159), and questionable (n=11). The most accurate algorithm was including patients with ≥1 visits with psoriasis as primary diagnostic codes and prescription of vitamin D derivatives. Its positive predictive value was 96.5% (95% confidence interval [CI], 93.9%~98.1%), which was significantly higher than those of the algorithm, including patients with ≥1 visits with psoriasis as primary diagnostic codes or including ≥1 visits with diagnostic codes of psoriasis (primary or additional) (91.0% and 69.8%). Sensitivity was 90.8% (95% CI, 87.2%~93.4%) and specificity was 92.5% (95% CI, 86.9%~95.9%).CONCLUSION: Our study demonstrates a validated algorithm to identify psoriasis, which will be useful for the nationwide population-based study of psoriasis in Korea.

RESUMO

BACKGROUND: Research into the Baumann skin type (BST) has recently expanded, with growing interest in the development of an efficient and effective skin type classification system for better understanding of this skin condition. OBJECTIVE: We aimed to identify male-specific skin type characteristics with investigation into the distribution of BST by age and region in the Korean male population and to determine the intrinsic and extrinsic factors related to skin type. METHODS: A questionnaire was administered to collect information about age, region, working behavior, drinking behavior, smoking behavior, usual habit of sun protection, medical history, and the BST which consisted of four parameters; oily (O) or dry (D), sensitive (S) or resistant (R), pigmented (P) or non-pigmented (N), and wrinkled (W) or tight (T). RESULTS: We surveyed 1,000 Korean males aged between 20 and 60 years who were divided equally by age and region. Of the total respondents, OSNW type accounted for the largest percentage and ORPW type the lowest. In terms of Baumann parameters, O type was 53.5%, S type was 56.1%, N type was 84.4% and W type was 57.5%. Several behavioral factors were found to have various relationships with the skin type. CONCLUSION: The predominant skin type in the Korean male respondents was OSNW type, and the distribution of skin types with regards to age and region was reported to be distinct. Therefore, skin care should be customized based on detailed skin types considering the various environmental factors.

RESUMO

A “pathogen resource” contains information about pathogens (e.g., bacteria, fungi, viruses, and protozoa) and microbial derivatives (e.g., DNA, RNA, plasmid, clone, and cDNA). Pathogen resources are important for their potential use in healthcare research because they contain clinical and epidemiological information that is different from microbial resources. In October 2014, the “Nagoya Protocol” on access and benefit-sharing with the Convention on Biological Diversity was enacted to restrict the movement of transboundary pathogens and protect the natural pathogen resources of each country. On July 2017, the Korean Medical Fungal Pathogen Resource Bank (KMFRB) was established to secure, discover, and develop biological resources focused on medical fungi. KMFRB has since been operating under the National Culture Collection for Pathogens of the National Institute of Health based on the Act No. 13992. This report aims to provide general information regarding KMFRB and suggest efficient ways to utilize human fungal pathogen resources for clinical research.

RESUMO

BACKGROUND: Adiponectin, an adipokine secreted from adipocytes, affects energy metabolism and also shows anti-diabetic and anti-inflammatory properties. Recent studies have reported that adiponectin plays a role in regulating skin inflammation. OBJECTIVE: This study aimed to investigate the effect of adiponectin on the expression of filaggrin (FLG) in normal human epidermal keratinocytes (NHEKs). METHODS: NHEKs were serum-starved for 6h before being treated with adiponectin. Afterward, cell viability was assessed by MTT assay. We also treated with calcium, interleukin (IL)-4, and IL-13 to provide positive and negative comparative controls, respectively. Gene mRNA expression was quantified using real time reverse transcription polymerase chain reaction, and protein expression was evaluated using Western blot. To evaluate the relationship among mitogen-activated protein kinases (MAPKs), activator protein 1 (AP-1), and FLG, we also treated cells with inhibitors for MAPKs JNK, p38, and ERK1/2. RESULTS: FLG and FLG-2 mRNA expression in NHEKs significantly increased after treatment with 10 µg/ml adiponectin. Adiponectin also restored FLG and FLG-2 mRNA expression that was otherwise inhibited by treatment with IL-4 and IL-13. Adiponectin induced FLG expression via AP-1 and MAPK signaling. CONCLUSION: Adiponectin positively regulated the expression of FLG and could be useful as a therapeutic agent to control diseases related to disrupted skin barrier function.

RESUMO

Deep vein thrombosis (DVT), which usually occurs in the lower extremities, is the presence of a blood clot within a deep vein that causes symptoms by breaking the venous return. Many cases of calf vein DVT are asymptomatic, or display only mild symptoms. But in the case of a proximal DVT, it affects the venous flow through the entire lower extremity, which results in a post-thrombotic syndrome, or a pulmonary embolism, if the proper treatment isn't performed. The diagnosis of the DVT is made by a radiologic examination. An ultrasound is often used as a first line of diagnosis, but on the other hand, computed tomography venography has also been gaining traction as an alternative method. If diagnosed, finding the cause of the DVT is important, and in the case of a symptomatic proximal DVT, the combination of anticoagulation and interventional treatment can be used towards the recovery of the venous return, preventing complications.

RESUMO

Although medical and endoscopic hemostasis is now considered as the first-line therapy for nonvariceal upper gastrointestinal (UGI) bleeding, refractory bleeding still occurs in 5%–10% of the patients. In these patients, transcatheter arterial embolization (TAE) or surgery is required, but research on embolization for unmanageable UGI bleeding in Korea is scanty. We reviewed the medical records of 518 patients who underwent endoscopic hemostasis during 4 years. Among these subjects, 8 patients who required embolization due to failure of endoscopic hemostasis were enrolled. Mean patient age was 74.00 ± 8.25 years, and rebleeding occurred in 4 patients within 48 hours after TAE. Three patients with duodenal rebleeding underwent surgery, and the other patient with a gastric ulcer underwent endoscopic hemostasis. Nonvariceal UGI bleeding remains a serious clinical challenge, especially in older patients. A multidisciplinary approach including endoscopists, interventional radiologists, and surgeons may be important for the treatment of nonvariceal UGI bleeding.

RESUMO

The neutral zone technique is an alternative approach for the construction of complete dentures on highly atrophic ridges with history of denture instability. This technique achieves two objectives. First, the teeth will not interfere with the normal muscle function, and second, the force exerted by the musculature against the denture is more favorable for stability and retention. In this case of a 78-years-old female patient with severely atrophic ridges who had been using unstable complete dentures, the neutral zone impression technique was used to increase the stability and the retention of dentures. The neutral zone for both arch was located with modeling compound. After the arrangement of artificial teeth within the neutral zone, the external impression was taken to determine the tissue surface. The final dentures showed enhanced stability and retention and the patient was satisfied with the new dentures with respect to functional and esthetic aspects.
