ABSTRACT
AIM:To investigate the factors affecting patients with post traumatic infectious endophthalmitis(PTIE)relieving from blindness.METHODS: A retrospective study was conducted on 169 patients(169 eyes)with PTIE from January 2010 to December 2020 in the department of ophthalmology, the Affiliated Hospital of Nantong University. After treatment of intravitreal injection of antibiotics(IVIA)and/or pars plana vitrectomy(PPV), the patients were divided into the getting rid of blindness group(103 eyes)and unilateral blindness group(66 eyes)according to the last follow-up of best correct visual acuity(BCVA)≥0.05. The factors affecting the patients to get rid of blindness were analyzed.RESULTS: The rate of relieving from blindness was 53.5%. Univariate analysis showed that BCVA before treatment ≥ hand movement, no retinal detachment, fundus grade of endophthalmitis < grade 3 and no strong virulence of infected microorganisms were beneficial for patients to get rid of blindness(P<0.05). Multivariate Logistic regression analysis identified that BCVA before treatment ≥ hand movement(OR=0.253, 95%CI: 0.108-0.592)and no retinal detachment(OR=0.241, 95%CI: 0.103-0.564)were favorable factors for patient to get rid of blindness.CONCLUSION: Better BCVA before treatment, no retinal detachment, endophthalmitis fundus grade < 3, and no strong virulence of infected microorganisms are favorable factors for patients with PTIE to get rid of blindness finally.
ABSTRACT
BACKGROUND@#Long segmental tracheal repair is challenging in regenerative medicine due to low adhesion of stem cells to tracheal scaffolds. Optimal transplantation of stem cells for tracheal defects has not been established. We evaluated the role of hyaluronic acid (HA) coating of tracheal scaffolds in mesenchymal stem cell (MSC) adhesion and tracheal regeneration in a rabbit model. @*METHODS@#A three-dimensionally printed tubular tracheal prosthesis was incubated with dopa-HA-fluorescein isothiocyanate in phosphate-buffered saline for 2 days. MSCs were incubated with an HA-coated scaffold, and their adhesion was evaluated by 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide assay. HA coated scaffolds with or without MSC seeding were transplanted at the circumferential tracheal defect in rabbits, and survival, rigid bronchoscopy, radiologic findings, and histologic findings were compared between the two groups. @*RESULTS@#HA-coated scaffolds showed better MSC adhesion than non-coated scaffolds. The HA-coated scaffolds with MSC group showed a wider airway and greater mucosal regeneration compared to the HA-coated scaffolds without MSC group. @*CONCLUSION@#HA coating of scaffolds can promote MSC adhesion and tracheal regeneration.
ABSTRACT
Purpose@#The aim of this study is to compare the hardness according to the conditions of metal alloys. Moreover, the correlation between the cast crown hardness before and after wear testing and the degree of wear for each dental alloy was assessed. @*Materials and Methods@#Cast crowns of three metal alloys (Co-Cr, gold, and Ni-Cr alloys) opposing smooth-surface monolithic zirconia were used. The Vickers microhardness of the ingot (which did not undergo wear testing) and the cast crown before and after wear testing were measured for each alloy. Two-way ANOVA and Scheffé tests were used to compare the measured hardness values. Moreover, the Pearson correlation coefficient was used to evaluate the relationship between the surface hardness and the wear of the cast crown (α=.05). @*Results@#There was no significant difference in the hardness before and after wear testing for the gold alloy (P >.05); however, the hardness of the worn surface of the cast crown increased compared to that of the cast crown before the wear tests of Ni-Cr and Co-Cr alloys (P .05). @*Conclusion@#There was a significant difference in hardness between dental alloys under the same conditions. No correlation existed between the surface hardness of the cast crown before and after wear testing and the wear of the cast crown.

ABSTRACT
Purpose@#A need for useful measures reflective of the socio-economic burden of chronic urticaria (CU) has arisen. To obtain utility estimates for CU, we investigated EuroQol-5-Dimension (EQ-5D) indices according to urticaria control status and urticaria severity. @*Methods@#In this prospective observational study, we administered patient-oriented questionnaires on EQ-5D and urticaria outcomes, including Urticaria Activity Score over 7 days (UAS7), Urticaria Control Test (UCT), and CU-specific quality of life (CU-QOL). EQ-5D utility index scores were compared according to urticaria control status and disease severity. Conditional process analysis (CPA) was used to map EQ-5D utility scores from UAS7 and UCT. @*Results@#Greater EQ-5D utility values were obtained in patients with better urticaria control (0.91 ± 0.10 for well controlled CU, 0.84 ± 0.12 for partly controlled, 0.77 ± 0.14 for uncontrolled, P < 0.001). According to CU severity, mean utility values were ranged from 0.746 (severe, UAS7 ≥ 28) to 0.860 (moderate), 0.878 (mild), and 0.953 (urticaria free). CPA suggested that UAS7 was directly correlated with UCT (regression coefficient, −0.251; 95% confidence interval [CI], −0.278, −0.223; P < 0.001) and EQ-5D utility (−0.002; 95% CI, −0.003, −0.001; P = 0.007) after controlling for age, sex, urticaria duration, and combined allergic diseases. @*Conclusions@#EQ-5D values increased with improvement in urticaria control and decreased with urticaria severity. A predictive model mapping EQ-5D utility from UAS7 and UCT scores suggested that EQ-5D can be useful for the pharmacoeconomic evaluation of individualized treatments for CU patients.
ABSTRACT
Purpose@#The purpose of this study was to compare the axial displacement of the hexagonal and conical abutment in internal conical connection implant after screw tightening and cyclic loading. @*Materials and Methods@#Internal conical connection implants were divided into two groups (n = 10): group HEX, hexagonal abutment; and group CON, conical 2-piece abutments. The axial displacement and removal torque values were measured after 30 Ncm torque tightening and 250N loading test of 100,000 cycles. The Student t test with 5% significance level was used to evaluate the data. @*Results@#HEX group demonstrated significantly higher axial displacement values after 30 Ncm tightening in comparison to the CON group (P < 0.05). No significant difference was found in axial displacement after cyclic loading (P = 0.052). Removal torque loss before and after the cyclic loading both revealed no significant difference between groups (P = 0.057 and P = 0.138). Removal torque value decreased after cyclic loading in both groups (P < 0.05). @*Conclusion@#Overall, both abutment with or without hexagon index presented similar biomechanical performance except HEX group demonstrated significantly more axial displacement after applying tightening torque.

ABSTRACT
Subcutaneous facial emphysema after dental treatment is an uncommon complication caused by the invasion of high-pressure air; in severe cases, it can spread to the neck, mediastinum, and thorax, resulting in cervical emphysema, pneumomediastinum, and pneumothorax. The present case showed subcutaneous cervicofacial emphysema with pneumomediastinum after class V restoration. The patient was fully recovered after eight days of conservative treatment. The cause of this case was the penetration of high-pressure air through the gingival sulcus, which had a weakened gingival attachment. This case indicated that dentists should be careful to prevent subcutaneous emphysema during common dental treatments using a high-speed hand piece and gingival retraction cord.

In restorative treatment using fixed dental prostheses, dentists should select appropriate restoration material among various types of dental materials. The strength, marginal fit, esthetics, wear resistance, biocompatibility, and cost are important factors in the choice of restoration materials. The present case showed a surface stain on a monolithic zirconia restoration that was due to wear between the monolithic zirconia restoration and the base metal alloy restoration. This phenomenon was confirmed by surface roughness measurement and electron probe micro-analysis.

BACKGROUND: With the development of technology, extensive use of computers in the workplace is prevalent and increases efficiency. However, computer users are facing new harmful working conditions with high workloads and longer hours. This study aimed to investigate the association between computer use at work and self-reported depressive and anxiety disorder (DAD) in a nationally representative sample of South Korean workers. METHODS: This cross-sectional study was based on the third Korean Working Conditions Survey (2011), and 48,850 workers were analyzed. Information about computer use and DAD was obtained from a self-administered questionnaire. We investigated the relation between computer use at work and DAD using logistic regression. RESULTS: The 12-month prevalence of DAD in computer-using workers was 1.46 %. After adjustment for socio-demographic factors, the odds ratio for DAD was higher in workers using computers more than 75 % of their workday (OR 1.69, 95 % CI 1.30−2.20) than in workers using computers less than 50 % of their shift. After stratifying by working hours, computer use for over 75 % of the work time was significantly associated with increased odds of DAD in 20–39, 41–50, 51–60, and over 60 working hours per week. After stratifying by occupation, education, and job status, computer use for more than 75 % of the work time was related with higher odds of DAD in sales and service workers, those with high school and college education, and those who were self-employed and employers. CONCLUSIONS: A high proportion of computer use at work may be associated with depressive and anxiety disorder. This finding suggests the necessity of a work guideline to help the workers suffering from high computer use at work.

BACKGROUND: The aims of present study were (1) to evaluate new bone formation among the 4-hexylresorcinol (4HR)-incorporated silk fabric membrane (SFM), conventional SFM, and uncovered control groups and (2) to compare the amount of residual membrane between the 4HR-incorporated SFM and conventional SFM in a rabbit parietal defect model. METHODS: Nine New Zealand white rabbits were used for this animal study. After the formation of a bilateral parietal bone defect (diameter 8.0 mm), either 4HR-incorporated SFM or conventional SFM was grafted into the defect. The defect in the control was left uncovered. New bone formation and the amount of residual membrane were evaluated by histomorphometry at 8 weeks after the operation. RESULTS: The total amount of new bone was 37.84 +/- 8.30 % in the control, 56.64 +/- 15.74 % in the 4HR-incorporated SFM group, and 53.35 +/- 10.52 % in the conventional SFM group 8 weeks after the operation. The differences were significant between the control and 4HR-incorporated SFM group (P = 0.016) and between the control and conventional SFM group (P = 0.040). The residual membrane was 75.08 +/- 10.52 % in the 4HR-incorporated SFM group and 92.23 +/- 5.46 % in the conventional SFM group 8 weeks after the operation. The difference was significant (P = 0.039). CONCLUSIONS: The 4HR-incorporated SFM and conventional SFM groups showed more bone regeneration than the control group. The incorporated 4HR accelerated the partial degradation of the silk fabric membrane in a rabbit parietal defect model 8 weeks after the operation.

Background The clinical significance of complete revascularization for ST segment elevation myocardial infarction (STEMI) pa-tients during admission is still debatable. Methods A total of 1406 STEMI patients from the Korean Myocardial Infarction Registry with multivessel diseases without cardiogenic shock who underwent primary percutaneous coronary intervention (PPCI) were analyzed. We used propensity score matching (PSM) to control differences of baseline characteristics between culprit only intervention (CP) and multivessel percutaneous coronary interventions (MP), and between double vessel disease (DVD) and triple vessel disease (TVD). The major adverse cardiac event (MACE) was analyzed for one year after discharge. Results TVD patients showed higher incidence of MACE (14.2%vs. 8.6%, P=0.01), any cause of revascularization (10.6%vs. 5.9%, P=0.01), and repeated PCI (9.5%vs. 5.7%, P=0.02), as compared to DVD patients during one year after discharge. MP reduced MACE effectively (7.3%vs. 13.8%, P=0.03), as compared to CP for one year, but all cause of death (1.6%vs. 3.2%, P=0.38), MI (0.4%vs. 0.8%, P=1.00), and any cause of revascularization (5.3%vs. 9.7%, P=0.09) were comparable in the two treatment groups. Conclusions STEMI patients with TVD showed higher rate of MACE, as compared to DVD. MP performed during PPCI or ad hoc during admission for STEMI patients without cardiogenic shock showed lower rate of MACE in this large scaled database. Therefore, MP could be considered as an effective treatment option for STEMI patients without cardiogenic shock.
ABSTRACT
Castleman's disease (CD) is a rare lymphoproliferative disorder that can involve single or multiple lymph nodes in the body. Especially, the localized form of CD is known to be well-controlled by using a surgical resection. On occasion, the surgeon may confront an abdominal and retroperitoneal mass of unknown origin. Thus, we present this case in which we treated a 16-year-old female patient for CD and investigated how to evaluate and manage the situation from the standpoint of CD. Also, we give a review of the pathology, clinical manifestation, diagnosis, and treatment of CD.

Onlay bone grafting, guided bone regeneration, and alveolar ridge split technique are considered reliable bone augmentation methods on the horizontally atrophic alveolar ridge. Among these techniques, alveolar ridge split procedures are technique-sensitive and difficult to perform in the posterior mandible. This case report describes successful implant placement with the use of piezoelectric hinge-assisted ridge split technique in an atrophic posterior mandible.

PURPOSE: The aim of this study was to evaluate clinical outcomes of implant supported fixed-hybrid prostheses (FHP) in the fully edentulous arches. MATERIALS AND METHODS: Patients in this retrospective study were restored with fixed-hybrid prostheses supported by 4 to 6 implants and functioned more than 1 year of loading. Outcome measures were marginal bone change of implant related with sex, anatomical location (maxilla vs. mandible), opposing teeth, loading time of patients, tilting of posterior implant by Mann-Whitney U test and cantilever length of superstructure by regression analysis, and complication rates. Significance level was set P.05), and cantilever length was not significantly related with a marginal bone loss of implant next to cantilever (P>.05). Complication was shown in 11 patients and veneer fracture and dislodging of artificial teeth were most prevalent. CONCLUSION: Within the limitations of this study, although marginal bone loss of FHP was very little, complication rates were high. Irrespective of tilting of most posterior implants, marginal bone loss of most posterior implants next to cantilever was less than those of the other implants positioned anteriorly. Cantilever length (<17 mm) did not affect a marginal bone loss of most posterior implants.

PURPOSE: Use of bipolar electocoagulation devices becomes popular in the laparoscopic surgical field. However, several studies comparing energy-based devices for use in performance of mechanical sealing and cutting techniques have reported various results. The aim of this study was to evaluate feasibility and efficacy of new commercially available bipolar electocoagulation devices: EnSeal(TM) device (Ethicon Endo-Surgery, Cincinnati, OH, USA) by comparison with LigaSure(TM) atlas 5 mm (COVIDIEN, Boulder, CO, USA), for use in performance of coagulation and cutting techniques during performance of laparoscopic colorectal cancer surgery. METHODS: Between June 2010 and February 2011, 50 consecutive patients who underwent curative laparoscopic surgery for right colon cancer or rectal cancer were enrolled. Time and number of device activations were compared during omentectomy in cases of right colectomy and mesorectal trimming procedure in cases of anterior resection. Pathologic data and short-term clinical outcomes were also compared. RESULTS: No significant differences in terms of clinicopathologic comparison were observed between the EnSeal and LigaSure groups. No significant difference in mean operative time (207.6+/-45.3 vs. 198.9+/-57.2; p=0.558), mean time of omentectomy (11.0+/-4.5 vs. 12.6+/-8.6; p=0.293), mean time of m esorectal trimming (18.6+/-10.0 vs. 16.1+/-6.9; p=0.418), mean number of device activations during omentectomy (43.5+/-10.2 vs. 51.6+/-39.2; p=0.586), and mean number of device activations during performance of mesorectal trimming (44.8+/-22.3 vs. 49.1+/-23.7; p=0.597) were observed between the two groups. CONCLUSION: Bipolar electocoagulation devices were adapted for use in laparoscopic surgery, resulting in reduced operative time and blood loss. EnSeal(TM) Device and LigaSure(TM) atlas 5 mm were useful during performance of sealing and cutting techniques in laparoscopic colorectal cancer surgery.

PURPOSE: The aim of this study is to evaluate the efficacy and the safety of additional 4-week chemotherapy with capecitabine during the resting periods after a 6-week neoadjuvant chemoradiotherapy (NCRT) in patients with locally advanced rectal cancer. METHODS: Radiotherapy was delivered to the whole pelvis at a total dose of 50.4 Gy for 6 weeks. Oral capecitabine was administered at a dose of 825 mg/m2 twice daily for 10 weeks. Surgery was performed 2-4 weeks following the completion of chemotherapy. RESULTS: Between January 2010 and September 2011, 44 patients were enrolled. Forty-three patients underwent surgery, and 41 patients completed the scheduled treatment. Pathologic complete remission (pCR) was noted in 9 patients (20.9%). T down-staging and N down-staging were observed in 32 patients (74.4%) and 33 patients (76.7%), respectively. Grade 3 to 5 toxicity was noted in 5 patients (11.4%). The pCR rate was similar with the pCR rates obtained after conventional NCRT at our institute and at other institutes. CONCLUSION: This study showed that additional 4-week chemotherapy with capecitabine during the resting periods after 6-week NCRT was safe, but it was no more effective than conventional NCRT.

PURPOSE: The incidence of community-acquired urinary tract infection (UTI) due to extended-spectrum beta-lactamase producing Escherichia coli (ESBL(+) E. coli) has increased worldwide. ESBL causes resistance to various types of the newer beta-lactam antibiotics, including the expanded spectrum cephalosporins and monobactams. We aimed to investigate the severity of UTI and associated genitourinary malformations in children with febrile UTI caused by ESBL(+) E. coli. METHODS: We retrospectively reviewed the medical records of 290 patients diagnosed as febrile UTI caused by E. coli between January 2008 and October 2010 at Korea University Medical center. We classified the patients into two groups with ESBL(+) and ESBL(-) E. coli group according to the sensitivity of urine culture. Fever duration, admission period, white blood cell (WBC) counts and C-reactive protein (CRP) in peripheral blood, the presence of hydronephrosis, cortical defects, vesicoureteral reflux (VUR) and renal scar were compared between the two groups. RESULTS: Patients with ESBL(+) E. coli were 32, and those with ESBL(-) E. coli were 258. If we excluded those tested with a sterile urine bag, patients with ESBL(+) E. coli were 22, and those with ESBL(-) E. coli were 212. Whether the results of sterile urine bag tests were included or not, there was no significant difference in all parameters between the two groups statistically. CONCLUSION: Our data shows that ESBL(+) E. coli may not be related to the severity of UTI and associated genitourinary malformations.
