PURPOSE: This study examined the postoperative long-term results of the reconstruction of orbital wall fracture using Macropore(R). METHODS: The long-term results for 10 patients who were diagnosed with orbital wall fracture and received the repair of orbital wall fracture using Macropore(R), were examined postoperatively after an average of 23.5 months. RESULTS: The mean difference in orbital volume between the fractured orbit and the unaffected orbit after an average of 23.5 months postoperatively was 1.01+/-0.70 cm3 (4.75+/-2.92%), which slightly increased compared to 0.70+/-0.52 cm3 (3.26+/-2.10%) immediately after the operation, although the difference was not statistically significant (p-value=0.190). At the last follow-up, the shape of Macropore(R) was not observed in 3 out of the 10 patients, and intense ossification was observed at the site of fracture in 6 patients. At the last follow-up, one patient showed 1.5 mm enophthalmos, and the other patients did not show the occurrence of diplopia or the progress of enophthalmos. CONCLUSIONS: According to the long-term results of the reconstruction of orbital wall fracture, Macropore(R) is considered an implant that produces a safe and satisfactory effect without notable complications.

PURPOSE: To report two cases of successful acellular dermal allograft transplantation for scleromalacia following pterygium excision. CASE SUMMARY: A 72-year-old female patient developed scleromalacia on the nasal side of the right eye, and a 79-year-old female patient developed scleromalacia with inflammation on the nasal side of the left eye. They had previous histories of pterigia removal on the sites of scleromalacia. Acellular dermal allograft (AlloDerm(R), Lifecell, NJ, USA) transplantations were done. After the operations, inflammation and pain ameliorated and the grafts survived without any particular complications. CONCLUSIONS: In treating scleromalacia, the transplantation of acellular dermal allografts produced relatively satisfactory results without undesirable problems commonly encountered when using conventional materials.

Hemolytic property is a specific feature of bacteria to obtain iron which is essential for its survival in host tissues. Therefore, it is thought to be one of several factors of virulence. The purpose of this study was to investigate the hemolytic properties of Prevotella nigrescens isolated from the teeth diagnosed as pulp necrosis and apical periodontitis under the presence of hemolysin inhibitors such as NaN3 and dithiothreitol, heat, various pH and cultural conditions. The results were as follows; 1. Clinically isolated P. nigrescens strains and standard P. nigrscens ATCC 33563 showed hemolytic activity. 2. P. nigrescens showed higher hemolytic activity against human erythrocytes than sheep or horse erythrocytes. 3. NaN3 and dithiothreitol (DTT) reduced the hemolytic activity of P. nigrescens in a dose dependent manner (p < 0.05). 4. Optimal pH for the maximum hemolytic activity of P. nigrescens was 4.0 and the hemolysin was stable under the 50degrees C, but the hemolytic activity was significantly decreased at 95degrees C. 5. P. nigrescens cultured in 10% CO2 condition showed higher hemolytic activity than the bacteria cultured in the anaerobic condition.

PURPOSE: To report a case of acute orbital abscess after Medpor(R) implantation for orbital floor fracture repair. CASE SUMMARY: A 15-year-old boy who was punched in the right orbit visited our clinic because of diplopia. An orbital CT scan demonstrated a fracture of the right orbital floor. At surgery, a Medpor sheet was placed over the orbital floor defect. Over the first three days, clinical improvement was gradual, but at four days postoperatively, depression of the right eye was restricted, and lower lid edema and proptosis was present in the right eye. At eight days postoperatively, the orbital CT scan showed a large cystic mass surrounding the Medpor sheet and fine needle aspiration cytology showed a number of inflammatory cells. Because systemic antibiotics were ineffective, the Medpo(R) sheet and the cystic mass were removed through a transconjunctival approach to the orbit. A culture of the removed Medpor(R) sheet grew Staphylococcus aureus and signs of inflammatory cells in the tissue were present. After removal of the abscess, most clinical symptoms showed improvement except for the remaining depression of the right eye. CONCLUSIONS: Symptoms of eye movement restriction, lower lid edema, and proptosis may be uncommon after orbital floor fracture repair but can occur. We should also consider the possibility of abscess formation due to infection of the implant and emphasize the importance of prompt diagnosis and treatment of such a case.

Underserved area is a region that has a lack of healthcare resources. In the context of Korea, however, there are not enough detailed criteria for underserved areas. In this study, we aimed to develop indicators for underserved area through Delphi technique. We systematically reviewed the existing measure of underserved area. Sixty indicators were extracted as candidates across four domains in secondary medical care. Four domains are demand, medical resource, quality of care, and health outcome. To develop indicator, two round Delphi survey was conducted among 15 professional experts such as professionals and public administrators. In conclusion, 2 final indicators (accessibility, medical utilization) was determined as an appropriate measure in order to designate underserved area for secondary medical services. Using our criteria from Delphi technique, 36 areas were found as underserved areas for the secondary medical care.

Purpose: To identify the effect of a new leadership type by confirming the effect of clinical nurses' grit and nursing work environment on nursing performance and retention intention with the mediating effect of compassionate rationalism leadership in the process. Methods: A proportional stratified sampling method was used with 45 tertiary general hospitals nationwide as the sampling unit. An online survey targeting nurses who have been working continuously for more than one year was conducted from October 14 to November 9, 2022. The final analysis included 1,256 questionnaires. The correlation between the participants' variables was analyzed using Pearson's correlation coefficients. The mediating effect was confirmed using a regression analysis, and bootstrapping. Results: The compassionate rationalism leadership had a mediating effect on the relationship between grit and nursing performance (F=203.21, p<.001), nursing work environment and nursing performance (F=109.48, p<.001), grit and retention intention (F=149.90, p<.001), and nursing work environment and retention intention (F=25.14, p<.001). Conclusion The compassionate rationalism leadership of nursing managers had a positive effect on nursing performance and retention intention.Therefore, with the development and application of educational programs of compassionate rationalism leadership, it can be used to improve nursing performance and operate an efficient nursing organization.

Salmonellosis is one of communicable disease and still occur in sporadic in Korea frequently. They are four main clinical manifestations in salmonellosis. They are gastroenteritis, typhoidal or septisemia syndrome, focal manifestation and carrier state. Among them, focal manifestation is rarely seen. Saphra, et al. reported that localized salmonella infection is about 5%. Localized salmonella infection frequently occur during salmonella bacteremia, but may also occur with enteric fever or gastroenteritis. Gray, et al reported 3390 cases of minor gunshot wound infection that bacterial isolates from infected wounds consisted of Staphylococcus aureus(90%), Streptococcus sp.(6%), and mixed organisms(4%). Incresed host susceptibility to infection secondary to lowered resistance due to debilitating disease is an important determinant of Salmonella infection. Since salmonella is seldom suspected as a cause of soft tissue infections,there is usually a dangerous delay in the institution of appropriate antimicrobial therapy and isolation procedure. We experienced one case of subcutaneous salmonella abscess developed on gunshot wound area in lung cancer patient, which was confirmed by pus culture.
