ABSTRACT
Background@#Cyclosporine (CS) has been effectively used in various skin diseases, but gastrointestinal (GI) adverse events are so common. However, there is no standardized treatment for managing CS-induced GI adverse events. @*Objective@#To analyze the effectiveness of two empirical GI medications, an H2 receptor antagonist (H2RA) and proton pump inhibitor (PPI), in relieving CS-induced GI adverse events. @*Methods@#This is a prospective, randomized clinical trial conducted at Ajou University Hospital. The patients completed a gastrointestinal symptom rating scale (GSRS) questionnaire to assess GI symptoms before and after taking the drugs. @*Results@#A total of 60 patients, divided into a PPI group (n=30) and an H2RA group (n=30), were analyzed. The onset of GI events occurred in 6.04 days on average. GSRS scores improved significantly in both groups (p＜0.01). While abdominal pain, reflux syndrome, and indigestion syndrome consistently improved, changes in diarrhea syndrome and constipation syndrome were not statistically significant. The overall change in GSRS scores was higher in the PPI group, but the difference was not significant (p=0.76). @*Conclusion@#Both PPI and H2RA significantly improved CS-induced GI side effects, with PPI showing a slight advantage over H2RA, but the cost of PPIs should be considered when deciding on first-line therapy. GI side effects typically appeared within 6.04 days of starting CS therapy, highlighting the importance of close monitoring and personalized intervention for improving patient compliance.
ABSTRACT
Vitiligo has been considered an unexplained paradoxical phenomenon during biologics use.Herein, we report an adult case of progression of pre-existing vitiligo during secukinumab treatment for psoriasis, and we also examined the immunohistochemical changes in relation to biologics use. He was being administered monthly secukinumab of 300 mg dose for 2 years, and all psoriatic lesions were cleared, but pre-existing hypopigmented lesions became more distinct and larger than before unlike when using adalimumab. A skin biopsy of the hypopigmented lesion showed loss of epidermal melanocytes and absence of gp100 immune activities, and he was finally diagnosed with progression of pre-existing vitiligo.Immunohistochemical staining of vitiligo lesion showed decrease in interleukin-17 and tumor necrosis factor-α and increase in CD8+ T cells, interferon-γ, and CXCL10 after the use of secukinumab. In this study, we suggest that biologics-induced cytokine imbalance play a critical role in vitiligo progression in patients with chronic inflammatory diseases, including psoriasis.
ABSTRACT
Background@#The primary goal of scabies treatment is to eliminate mites; however, but post-scabetic itch persists in many patients. Since long-standing itching can lead to the development of other comorbidities, appropriate interventions are necessary. @*Objective@#This study aimed to investigate the effects of inappropriate (continuous or prolonged) scabicide use and oral steroids on the duration of pruritus in patients with scabies. @*Methods@#The duration of pruritus, use of oral corticosteroids, total immunoglobulin E (IgE) levels, specific IgE levels for house dust mites, and eosinophil counts were evaluated. Post-scabetic itch was defined as itching that persisted for more than 3 weeks, although scabies was no longer detected; 208 participants with post-scabetic itch were included. @*Results@#We recruited 265 participants with confirmatory diagnosis of scabies and 116 with clinical diagnosis. We treated 124 participants with scabicides based on the guidelines, whereas 257 participants were not. The type of scabicide did not affect the duration of pruritus. Scabicide overuse did not shorten the duration of pruritus; however, its prolonged use lengthened the treatment period. Although oral corticosteroids did not shorten the duration of pruritus in the patients, they were effective when the patient had post-scabetic itch. In addition, a positive correlation between the total IgE level and duration of pruritus was observed. @*Conclusion@#This study investigated the effect of treatment modality on the clinical course of scabies. Our findings suggest that overuse of scabicides might be associated with post-scabetic itch, and short-term use of oral corticosteroids may be effective in reducing its duration.
ABSTRACT
Erythema multiforme (EM) is an acute, self-limited mucocutaneous disease with diverse triggering factors, and the recurrences are quite common. A 24-year old male presented with multiple erythematous, itchy papules and plaques on multiple sites. He has worked in a lithium battery factory and experienced the chemical burn 2 weeks ago. A histopathologic examination on right wrist showed a scattered lymphocytic infiltration, vacuolar degeneration, and necrotic keratinocyte. The final diagnosis was EM after occupational lithium exposure. He was treated by oral methylprednisolone and experienced recurrences after returning to the same workplace after remission. Although the precise pathogenesis is unknown, the pathogenesis of EM by lithium is related to the effect of lithium on immune system, different from other etiologies. To our knowledge, our case is the first report of EM following the chemical burn and occupational lithium exposure. We report this as an interesting case of EM.
ABSTRACT
Epithelioid hemangioma is a rare benign vascular neoplasm. Recently, the term “multiple eruptive epithelioid hemangioma” has been proposed for epithelioid hemangioma with distinct features. It is different from usual epithelioid hemangioma because of the multifocal distributions in various body regions with an eruptive onset. In addition, the histopathology of multiple eruptive epithelioid hemangioma shows increased cellular proliferation, mitosis, and nuclear pleomorphism and positive findings for FOS-B compared to classic epithelioid hemangioma. Herein, we report the case of a 59-year-old man with unusual manifestations suitable for multiple eruptive epithelioid hemangioma. He had multiple erythematous to purple-red dome-shaped nodules on the right hand, arm, and shoulder. The initial lesion was a solitary erythematous nodule on the right hand that abruptly extended to the right arm and shoulder. Microscopically, the tumor was a well-demarcated dermal nodule and showed capillary sized vascular structures. Vascular structures had epithelioid endothelial cells with abundant eosinophilic cytoplasm and vesicular nuclei. The tumor cells showed mild nuclear pleomorphism and a few mitosis and feature of resembling cobble stone was observed. In immunohistochemistry, CD31 and CD34 were positive in the endothelial cells.The endothelial cells showed nuclear positivity in FOS-B. Based on the clinical and histopathological findings, the final diagnosis was multiple eruptive epithelioid hemangiomas.This is the first report of multiple eruptive epithelioid hemangiomas in an Asian man after the term had been introduced.
ABSTRACT
Purpose@#This study was examined to improve the standing posture of a scoliosis client using the ICF Tool. @*Methods@#For examination, the study subject was a 16-year-old female student diagnosed with 3curve-pelvic (3CP) type scoliosis. Information about her were collected through a client interview and based on international Classification of Functioning, Disability and Health (ICF). The ICF core set was for post-acute musculoskeletal conditions, and the ICF level 2 items suggested by National Rehabilitation Information Center (NARIC) were added to the recommendations for scoliosis. For evaluation, the ICF assessment sheet was used to identify the interaction among the problems. For the diagnosis, the client’s functional problems were described in ICF terms. For the prognosis, the global goals for reaching the client’s functional activity and participation level were presented as the long-and short-term goals. For the intervention, a coordinative locomotor training program composed of warm-up, main exercise, and cool-down was applied 3 times a week, 50 minutes a day, for 5 weeks. For the outcome, the differences between before and after the intervention were compared with the ICF qualifier and are shown with the ICF evaluation display. @*Results@#Clinical advantages were observed in body function and structure (7° decrease of thoracic angle, 7 score increase of trunk muscle power, 6.47s improve of one leg standing, 4 score decrease of neck pain). The activity for maintaining the standing posture, in which the client had a primary limitation, was improved. @*Conclusion@#Applying the coordinative locomotor training program is expected to improve scoliosis client’s standing posture.
ABSTRACT
Verrucous carcinoma is a rare, low-grade, well-differentiated variant of squamous cell carcinoma. It occurs mainly on the soles, but has also been reported in other locations, including the buttocks, hand, anus, and genitalia. A 38-year-old woman presented with an asymptomatic skin lesion of the nipple. She first noticed the lesion three months prior. A solitary, cauliflower-shaped, black polypoid mass was observed on her right nipple.Histopathological examination revealed a superficial lesion resembling verruca vulgaris. It was composed of relatively well-differentiated cells with severe epidermal proliferation, and some tumor cells were observed in the dermis. The final diagnosis was verrucous carcinoma. Complete excision of all the lesions was performed. The patient had no recurrence. We report an interesting case of verrucous carcinoma that occurred at a relatively rare site; only one previous report of verrucous carcinoma associated with the breast or nipple was found.

ABSTRACT
An endolichenic fungus Xylaria grammica EL000614 produces grammicin, a potent nematicidal pyrone derivative that can serve as a new control option for root-knot nematodes. We optimized an Agrobacterium tumefaciens-mediated transformation (ATMT) protocol for X.grammica to support genetic studies. Transformants were successfully generated after co-cultivation of homogenized young mycelia of X.grammica with A. tumefaciens strain AGL-1 carrying a binary vector that contains the bacterial hygromycin B phosphotransferase (hph) gene and the eGFP gene in T-DNA. The resulting transformants were mitotically stable, and PCR analysis showed the integratin of both genes in the genome of transformants.Expression of eGFP was confirmed via fluorescence microscopy. Southern analysis showed that 131 (78.9%) out of 166 transformants contained a single T-DNA insertion. Crucial factors for producing predominantly single T-DNA transformants include 48 h of co-cultivation, pretreatment of A. tumefaciens cells with acetosyringone before co-cultivation, and using freshly prepared mycelia. The established ATMT protocol offers an efficient tool for random insertional mutagenesis and gene transfer in studying the biology and ecology ofX.grammica.

ABSTRACT
Background@#Psoriasis is a chronic relapsing inflammatory disease, with several cytokines related to its pathophysiology and clinical manifestations, such as disease activity, severity, and clinical subtype. However, there is limited information regarding Korean psoriasis patients.Objective We investigated the association between serum inflammatory cytokines and clinical characteristics of psoriasis, including treatment modalities. @*Methods@#We evaluated the serum Th17-related cytokine levels of 70 patients diagnosed with psoriasis using a multiplex immunoassay. All clinical information of patients was collected by reviewing electronic medical records and photo documentation in a retrospective manner. @*Results@#The serum IL-23 level was significantly higher in the young age group (＜40 years), and the IL-6, TNFβ, and IL-28A levels were significantly higher in the early onset group (＜40 years). In addition, patients with moderate-to-severe psoriasis (PASI≥10 and body surface area ≥10%) exhibited significantly lower serum IL-28A levels. We observed high serum TNF-α and CCL20 levels in patients with metabolic comorbidities and those with psoriatic arthritis, respectively, and biologics use and systemic treatment modality were also significantly associated with the serum levels of some cytokines. @*Conclusion@#Disease severity, comorbidities, presence of psoriatic arthritis, and treatment responsiveness might affect the inflammatory cytokine levels in psoriasis patients. Therefore, the serum cytokine levels can be used to predict the severity or treatment responsiveness of psoriasis patients.
ABSTRACT
PURPOSE: This study aimed to evaluate the effect of two different implant-abutment connection structures with identical implant design on peri-implant bone level. MATERIALS AND METHODS: This clinical study was a patient-blind randomized controlled trial following the CONSORT 2010 checklists. This trial was conducted in 24 patients recruited between March 2013 and July 2015. Implants with internal friction connection were compared to those with external hex connection. One implant for each patient was installed, replacing the second molar. Implant-supported crowns were delivered at four months after implant insertion. Standardized periapical radiographs were taken at prosthesis delivery (baseline), and one year after delivery. On the radiographs, distance from implant shoulder to first bone-to-implant contact (DIB) and peri-implant area were measured, which were the primary and secondary outcome, respectively. RESULTS: Eleven external and eleven internal implants were analyzed. Mean changes of DIB from baseline to 1-year postloading were 0.59 (0.95) mm for the external and 0.01 (0.68) mm for the internal connection. Although no significant differences were found between the two groups, medium effect size was found in DIB between the connections (Cohen's d = 0.67). CONCLUSION: Considering the effect size in DIB, this study suggested the possibility of the internal friction connection structure for more effective preservation of marginal bone.

BACKGROUND: Exacerbations of chronic obstructive pulmonary disease (COPD) are common and can be fatal. However, it is difficult to predict the in-hospital mortality, severity and prognosis of patients. Prognostic tools are needed to assess exacerbations of COPD in the emergency department. Towards this end, we compared DECAF (dyspnea, eosinopenia, consolidation, acidemia, atrial fibrillation) score with other prognostic tools available in the emergency department. METHODS: Consecutive patients admitted to the emergency department with exacerbations of COPD were recruited. We compared the DECAF score to CAPS (chronic obstructive pulmonary disease and asthma physiology score), BAP (blood urea nitrogen, altered mental status, pulse)-65 class and CURB (confusion, urea, respiratory rate, blood pressure)-65 score and assessed in-hospital mortality, endotracheal intubation, admission to the intensive care unit and admission to the hospital. RESULTS: The in-hospital mortality rate was 4.9%. The DECAF score showed excellent discrimination for in-hospital mortality (AUROC = 0.72, p = 0.002), endotracheal intubation (AUROC = 0.92, p < 0.001), admission to the intensive care unit (AUROC = 0.90, p < 0.001) and admission to the hospital (AUROC = 0.83, p < 0.001). CONCLUSIONS: The DECAF score is a simple and effective prognostic tool for assessing cases involving exacerbation of COPD in the emergency department. Emergency physicians should consider hospital admission if the DECAF score is more than 1 and consider admission to the intensive care unit and endotracheal intubation if the DECAF score is more than 3.

We evaluated in vitro microleakage of Mineral Trioxide Aggregate (MTA) powder with 4-methacryloxyethyl trimellitate anhydride (4-META) / methyl methacrylate (MMA) & tri-n-butylborane (TBB) resin as a retrograde filling material by using methylene blue dye method. Fifty-two single rooted, extracted teeth were instrumented and obturated with gutta percha and AH plus sealer. The apical 3mm of each root was resected and 3mm deep ultrasonic root end preparation was done. External surface of roots was coated with nail varnish. Prepared teeth were randomly divided into five groups; Negative control: completely covered with nail varnish; Positive control: coated with nail varnish except for apical foramen; Group 1 (retrofilled with Portland cement); Group 2 (retrofilled with MTA); Group 3 (retrofilled with MTA powder mixed with 4-META/MMA & TBB resin). Immediately after completion of root-end filling, all specimens were submerged in methylene blue dye for 72 hours in 37degrees C incubator. The roots were longitudinally sectioned and measured for extent of dye penetration by three different examiners under microscope (x10). The results were statistically analyzed using one way ANOVA and Turkey's HSD test. No leakage was evident in negative control and complete leakage in positive control group. Group 3 showed significantly less leakage than group 1 and 2 (p 0.01). It was concluded that MTA powder with 4-META/MMA & TBB resin was excellent in reducing initial apical microleakage.

A squamous odontogenic tumor (SOT) is an epithelial originated benign tumor. It has been rarely reported and most was intramural type. We observed a case of SOT in the mandible. It was associated with the odontogenic cyst. It was shown positive to pancytokeratin and p53. Considering that the case was free from recurrence for 5 years after surgery, p53 positive did not seem to be related to the prognosis of the disease.

OBJECTIVE: The objective of this international comparative study was to investigate the clinical features and outcome of the treatment of infratemporal fossa abscess (IFA). STUDY DESIGN: This retrospective study was conducted at the Deptartment of Oral and Maxillofacial Surgery of Hallym University and "Iuliu Hatieganu" University of Medicine and Pharmacy. Ten-year records of patients were reviewed in Romania and six-year records were reviewed in Korea. The collected data was then analyzed. RESULTS: A total of 36 cases were found to be IFA (12 males and 24 females: average age; 36.3+/-15.5 yrs: 34 cases from Romania and 2 cases from Korea). The annual frequency of IFA in Romanian and Korean hospitals was 3.40 and 0.33 respectively (P<0.001). The etiology was septic anesthesia (33.3%), infection occurring after extraction (30.6%), periapical lesion (13.9%), impacted third molar (8.3%), post-extraction alveolitis (5.6%), and unknown (8.3%). A successful outcome was seen in 27 patients (75.0%) after initial treatment. The main complication after initial treatment was restricted movement of the mouth (9 cases). CONCLUSION: The etiology of IFA was various and minimal swelling hampered early diagnosis. To prevent IFA, preoperative painting with antiseptic agent must be stressed and proper drainage proved important to relieve pain and to prevent further complications.
