PURPOSE: The purpose of this study was to compare the validity of Onen's alternative grading system (AGS) with that of the APDRP and SFU grading systems in patients with isolated and complicated congenital hydronephrosis. METHODS: We retrospectively reviewed the medical records of 153 patients (204 renal units) diagnosed with congenital hydronephrosis between January 2002 and December 2011. We classified patients into 2 groups; isolated or complicated hydronephrosis. All renal units were graded according to anterior-posterior diameter of renal pelvis (APDRP), Society for Fetus Urology (SFU) and Onen's grading systems. We analyzed the prognosis of hydronephrosis, according to each grading system, at 2 years of age. RESULTS: There were 152 renal units with isolated hydronephrosis and 52 renal units with complicated hydronephrosis. The isolated hydronephrosis group had a lower grade according to Onen's AGS, and showed more frequent spontaneous remission by 2 years of age. There was more frequent obstruction (P=0.000) and surgical treatment (P=0.000) of units with high-grade hydronephrosis according to Onen's AGS. In the complicated hydronephrosis group the frequencies of spontaneous remission (P=0.015) and renal dysfunction (P=0.013) were significantly higher than those in high-grade hydronephrosis, as indicated by Onen's AGS. There were no significant differences in clinical outcomes among the highest grade groups, according to the 3 systems, in either isolated or complicated hydronephrosis. CONCLUSION: Onen's AGS reflects the prognosis of hydronephrosis as well as other grading systems in those with isolated hydronephrosis. It was better predictor of renal dysfunction in those with complicated hydronephrosis. However, Onen's AGS was not superior to the other grading systems in terms of predicting prognosis, especially in high-grade hydronephrosis.

Candida glabrata is a yeast that commensally colonizes the upper cervix and vagina and has low pathogenicity in immunocompetent hosts. Here we report a case of C. glabrata chorioamnionitis and septic abortion following in vitro fertilization and embryo transfer (IVF-ET). This case suggests that infection in the upper vagina and cervix should be considered prior to having IVF-ET. We encountered a rare case of C. glabrata chorioamnionitis and septic abortion; therefore, we report this case with a review of the literature.

Background:
Self-leadership, an action strategy that can maximize individual capabilities, can affect the organizational commitment of dental hygienists and ultimately improve the quality of medical services. This study aims to demonstrate the need for self-leadership and organizational commitment for dental hygienists and develop measures to improve the quality of medical services.
Methods:
An online survey of dental hygienists working at dental hospitals and clinics in Seoul and Gyeonggi province, Republic of Korea was conducted from March 28 to May 1, 2022. A total of 341 questionnaires were returned and analyzed. The measurement tools were modified and supplemented based on the theories and models developed by Manz for self-leadership, Mowday for organizational commitment, and Cronin and Taylor for medical services. Descriptive statistics, independent t-tests, ANOVA, simple regression, and multiple regression analyses were performed using SPSS 25.0.
Results:
In leadership education, self-leadership is based on participation experience, the number of participants, and when and where it is received. Organizational commitment comes from participation experience, and the quality of medical services has been found to affect participation experience and location. Self-leadership had an effect on the quality of medical services (β=0.497, t=10.551, p<0.001; β =0.599, t=13.783, p<0.001; β=0.353, t=7.601, p<0.001) and organizational commitment was found to have a mediating effect.
Conclusion
Dental hygienists’ self-leadership has a positive effect on the quality of medical services through the formation of appropriate interrelationships within the organization. Therefore, self-leadership programs should be developed, participated in, and promoted to improve the self-leadership of dental hygienists. Moreover, hospitals should improve their environment to provide and improve self-leadership education.

Objectives:
. In subset of patients, acinic cell carcinoma (AcCC) exhibits aggressive features such as recurrence, distant metastasis, and mortality. This study aimed to investigate clinicopathologic factors influencing patients’ prognosis and to identify adverse features predictive of an unfavorable prognosis.
Methods:
. Between January 2000 and December 2016, 59 patients with AcCC were enrolled in this study.
Results:
. The patients’ 5-year overall survival rate was 93.3%, and their 5-year recurrence-free survival rate was 80.5%. During the study period, recurrence occurred in 10 patients. The mean time to recurrence after surgery was 26 months (range, 5–60 months). During the study period, three patients died from the disease. Univariate analysis showed that sex, surgical extent, extranodal extension, T classification, and TNM stage were significantly associated with disease recurrence. Multivariate analysis showed that, among the clinicopathologic factors included in the analysis, only TNM stage displayed a statistically significant correlation with disease recurrence.
Conclusion
. Surgical treatment alone yielded good results for AcCC, and additional treatment did not affect the recurrence-free survival rate or the overall survival rate, even when the resection margin was less than 1 mm. Other pathologic factors did not show prognostic significance for disease recurrence or death.

OBJECTIVES: To use focus-group interviews (FGI) to determine the current state of the Korean mental health service delivery system, inter-agency patient links, and identify associated problems. METHODS: The FGI were conducted by seven workers from psychiatric rehabilitation centers and community mental health centers and seven social workers from mental health hospitals. RESULTS: Within the mental health service delivery system, disconnection of the community network after discharge is considered a serious problem. The following improvement proposals are suggested : 1) the control tower should govern the community network after discharge, 2) consider insurance costs during activation of hospital links, and 3) expand information sharing related to community social facilities. With regard to non-voluntary admission and long-term hospitalization, most focus group members considered the revolving-door phenomenon to be more serious than non-voluntary admission. In order to prevent unnecessary long-term hospitalization, the FGI results indicated that the government should proactively intervene in the admission/discharge process. In addition, the following improvement proposals were suggested : 1) functional activation of the mental health review board via the reinforcement of workers' expertise, 2) expansion of local mental health centers, and 3) undertake institutional changes related to the family-related issue of preferring hospitalization over a stay at a secure facility. CONCLUSION: For the government to improve the efficiency of the mental health service delivery system, it is necessary to improve institutional linkages, expand mental health infrastructure, and develop an integrated management system.

Transarterial chemoembolization (TACE) is reportedly a useful palliative treatment in patients with unresectable or recurred hepatocellular carcinoma. Post-TACE complications are common; however, acute cholecystitis after TACE is rare. We herein report a case of a 73-year-old woman who presented with emphysematous cholecystitis and pneumobilia following TACE. Computed tomography performed for evaluation of her tumor status before TACE incidentally showed gallbladder and common bile duct stones. After TACE, she complained of severe epigastric pain with a positive Murphy's sign. Computed tomography showed emphysematous cholecystitis and pneumobilia. She was successfully treated with emergent biliary stone removal by endoscopic retrograde cholangiopancreatography.

Although guideline-based asthma therapy has had a positive impact on fatalities due to asthma over the last few decades, some patients refractory to or noncompliant with asthma treatment remain at risk of fatality. A 45-year-old female with refractory asthma and poor compliance and with a frequent history of hospitalization for asthma exacerbations was taken to the emergency room because of cardiorespiratory arrest. Her family reported that she had suffered from an upper respiratory infection followed by severe dyspnea for a few days. The patient developed status asthmaticus, and in spite of intensive cardiopulmonary resuscitation, she was eventually declared brain dead. The patient had not taken medication for asthma regularly for several months before the attack. Refractory and difficult-to-treat asthma should be aggressively monitored to prevent severe asthma exacerbations, which can be fatal, especially in noncompliant patients.

PURPOSE: Normal squamous cells do not exist in the orbit. Therefore squamous cell carcinoma of the orbit is rare and usually arises as a secondary tumor from distant metastasis or local invasion. The authors herein describe the first case of primary squamous cell carcinoma of the orbit in Korea. CASE SUMMARY: A 74-year-old female presented with a 2-month history of left upper eyelid swelling and ocular pain. On physical examination, a round, firm, fixed and tender mass was palpable in the superomedial side of the left orbit. Magnetic resonance imaging (MRI) showed 21 mm x 15 mm x 20 mm-sized irregular soft tissue mass with indistinct margin and peripheral enhancement in the superomedial portion of the left orbit, and incisional biopsy of the mass was performed. Histopathological examination showed clusters of squamous cells with polymorphic nuclei and interspersed keratin pearls, consistent with findings of well-differentiated squamous cell carcinoma. Despite extensive systemic work-up, there was no sign of extraorbital malignancy. The patient received left exenteration and adjuvant radiation therapy. Ten months after enucleation, a 12 mm x 14 mm sized firm mass developed on the left forehead, and excisional biopsy and frontalis rotational flap reconstruction were performed. Histopathological examination of the mass was consistent with well-differentiated squamous cell carcinoma. The patient remained alive 17 months after diagnosis without evidence of local recurrence or distant metastasis. CONCLUSIONS: Primary squamous cell carcinoma should be considered in the differential diagnosis of acutely progressing tumors of the orbit.

BACKGROUND: Vitamin D deficiency remains common in all age groups and affects skeletal and non-skeletal health. Fibroblast growth factor 23 is a bone-derived hormone that regulates phosphate and 1,25-dihydroxyvitamin D homeostasis as a counter regulatory factor. 1,25-Dihydroxyvitamin D stimulates fibroblast growth factor 23 synthesis in bone, while fibroblast growth factor 23 suppresses 1,25-dihydroxyvitamin D production in the kidney. The aim of this study was to evaluate the effects of vitamin D₃ intramuscular injection therapy on serum fibroblast growth factor 23 concentrations, and several other parameters associated with bone metabolism such as sclerostin, dickkopf-1, and parathyroid hormone. METHODS: A total of 34 subjects with vitamin D deficiency (defined by serum 25-hydroxyvitamin D levels below 20 ng/mL) were randomly assigned to either the vitamin D injection group (200,000 units) or placebo treatment group. Serum calcium, phosphate, urine calcium/creatinine, serum 25-hydroxyvitamin D, fibroblast growth factor 23, sclerostin, parathyroid hormone, and dickkopf-1 levels were serially measured after treatment. RESULTS: Comparing the vitamin D injection group with the placebo group, no significant changes were observed in serum fibroblast growth factor 23, parathyroid hormone, or dickkopf-1 levels. Serum sclerostin concentrations transiently increased at week 4 in the vitamin D group. However, these elevated levels declined later and there were no statistically significant differences as compared with baseline levels. CONCLUSION: Serum fibroblast factor 23, sclerostin, parathyroid hormone, and dickkopf-1 levels were not affected significantly by single intramuscular injection of vitamin D₃.

OBJECTIVE: There has been no prospective study that examined intramuscular injection of high-dose vitamin D in Korean adults. The aim of this study was to assess the efficacy and safety of high-dose vitamin D3 after intramuscular injection in Korean adults with vitamin D deficiency. METHODS: This study was a 24-week, prospective, multicenter, randomized, double-blind, placebo-controlled trial. A total of 84 subjects ≥19 and <65 years of age were randomly allocated to either the vitamin D3 or placebo group in a 2:1 ratio. After randomization, a single injection of plain vitamin D3 200,000 IU or placebo was intramuscularly administered. If serum 25-hydroxyvitamin D (25[OH]D) concentrations were <30 ng/mL on week 12 or thereafter, a repeat injection was administered. RESULTS: After a single intramuscular injection of vitamin D3 to adults with vitamin D deficiency, the proportion of subjects with serum 25(OH)D concentrations ≥30 ng/mL within 12 weeks was 46.4% in the vitamin D3 group and 3.6% in the placebo group (p < 0.0001). The proportion of subjects with serum 25(OH)D concentrations ≥30 ng/mL within 24 weeks was 73.2% in the vitamin D3 group and 3.6% in the placebo group (p < 0.0001). Mean change in serum 25(OH)D concentrations at weeks 12 and 24 after vitamin D3 injection was 12.8 ± 8.1 and 21.5 ± 8.1 ng/mL, respectively, in the vitamin D3 group, with no significant changes in the placebo group. Serum parathyroid hormone concentrations showed a significant decrease in the vitamin D3 group but no change in the placebo group. CONCLUSION: Intramuscular injection of vitamin D3 200,000 IU was superior to placebo in terms of its impact on serum 25(OH)D concentrations, and is considered to be safe and effective in Korean adults with vitamin D deficiency.
