BACKGROUND: Autologous fat grafts are widely used in plastic surgery, but they have the disadvantage of unpredictability due to variable resorption. This meta-analysis examined the literature on the survival rate of autologous fat grafts using objective markers, and investigated the factors that affected the survival rate. METHODS: The reviewers searched the PubMed, EMBASE, and Cochrane Library databases from January 2001 to December 2017. A meta-analysis was performed to estimate fat graft survival and to identify variables that influenced the survival rate. RESULTS: A total of 27 studies (1,066 cases) were included in the meta-analysis. The mean survival rate of grafted fat was 56.5%. The survival rate was significantly higher for cell-assisted lipotransfer (CAL) than for non-CAL (62% vs. 53.4%; P=0.015). The survival rate for procedures performed to correct lipoatrophy was higher than that of procedures performed for other purposes (64.6%; P=0.014), and was significantly higher in patients who underwent breast pre-expansion using the BRAVA device (66.2% vs. 50.35%; P=0.001). There were no significant differences in the survival rate according to the recipient site, harvesting method, or refinement method. CONCLUSIONS: Fat transplantation showed a varying survival rate, with an average of 56%. In patients who underwent CAL or breast pre-expansion with the BRAVA device, the survival rate of transplanted fat was higher than in their counterparts, supporting the use of these techniques in fat transplantation.

Background: This study evaluated changes in nasal airway function following Le Fort I osteotomy with maxillary impaction according to the Nasal Obstruction Symptom Evaluation (NOSE) scale. Methods: This cohort study included 13 patients who underwent Le Fort I osteotomy with maxillary impaction. Nasal airway function was evaluated based on the NOSE scale preoperatively and at 3 months postoperatively. The change in the NOSE score was calculated as the preoperative score minus the postoperative score. If the normality assumptions for changes in the NOSE score were not met, a nonparametric test (the Wilcoxon signed-rank test) was used. Differences in NOSE score changes according to patient characteristics and surgical factors were evaluated using the Kruskal-Wallis test and the Mann-Whitney test. Results: Patients ranged in age from 18 to 29 years (mean±standard deviation [SD], 23.00±3.87 years). Three were men and 10 were women. Eleven patients (84%) had an acquired dentofacial deformity with skeletal class III malocclusion. The preoperative NOSE scores ranged from 40 to 90 (mean±SD, 68.92±16.68), and the postoperative NOSE scores ranged from 25 to 80 (53.84±18.83). The cohort as a whole showed significant improvement in nasal airway function following maxillary impaction (P=0.028). Eleven patients (84%) had either improved (n=8) or unchanged (n=3) postoperative NOSE scores. However, nasal airway function deteriorated in two patients. Patient characteristics and surgical factors were not correlated with preoperative or postoperative NOSE scores. Conclusions Nasal airway function as evaluated using the NOSE scale improved after maxillary impaction.

The Korean sawmills have recently recognized the importance of prevention of fungal discoloration due to increased losses in revenue. Before establishing integrated control strategies of fungal discoloration, more complete knowledge about causal organisms is needed. As a first step, we initiated a through survey of fungi colonizing commercially important softwood (Pinus densiflora, Pinus koraiensis, and Pinus radiata) logs and lumber in Korea. In this paper we report results obtained from Japanese red pine (Pinus densiflora) log study. In summer 2000, fungi were isolated from Japanese red pine logs in storage, and identified based on their cultural and morphological characteristics. A total of 595 fungi were isolated, representing 21 genera and 30 species. Mold fungi, mostly Trichoderma species, were the most frequently isolating fungi, representing more than half of all isolates. Dematiaceous fungi represented approximately one fifth of the isolates, and Rhinocladiella atorvirens was the most abundant in all samples. Opiostoma species represented 7% of all isolates from cores planted on malt extract agar (MEA) and the incidence of these species doubled with the addition of streptomycin and cycloheximide to MEA. The results indicate that Japanese red pine sapwood is susceptible to colonization by a variety of fungal species. As a result, control strategies that concentrate on one fungus may have limited success because of interference from competing flora.

Background: Excessive bleeding is one of the most severe complications of orthognathic surgery (OGS). This study investigated the associations of intraoperative blood loss and surgical time with the direction of maxillary movement. Methods: This retrospective study involved patients who underwent OGS from October 2017 to February 2020. They were classified based on whether maxillary setback was performed into groups A1 and B1, respectively. Relative blood loss (RBL, %) was used as an indicator to compare intraoperative blood loss between the two groups. The surgical time of the two groups was also measured. Subsequently, the patients were reclassified based on whether posterior impaction of the maxilla was performed into groups A2 and B2, respectively. RBL and surgical time were measured in the two groups. Simple linear and multiple regression analyses were performed. P-values <0.05 were considered to indicate statistical significance. Results: Eighteen patients were included. The RBL and surgical time for the groups were: A1, 13.15%±5.99% and 194.37±42.04 minutes; B1, 12.41%±1.89% and 196.50±46.07 minutes; A2, 13.94%±3.82% and 201.00±39.70 minutes; and B2, 9.61%±3.27% and 188.84±38.63 minutes, respectively. Only RBL showed a statistically significant difference between the two groups (A2 and B2, P=0.04). Conclusions Unlike maxillary setback, posterior impaction of the maxilla showed a significant association with RBL during surgery. When performing posterior impaction of the maxilla, clinicians need to pay particular attention to surgery and postoperative care.

A nodular density was detected on a chest radiograph taken from a 57-year-old Korean woman who was visiting a hospital for a routine check. Chest computed tomography revealed a 4.8 cm lobulated mass in the right lung and another focal nodular lesion in the left lung; biopsies of both lungs revealed adenocarcinoma. We conducted DNA sequencing and peptide nucleic acid clamping to investigate the potential double primary lung cancer. The results verified that the mass in the right lung had a mutation in the epidermal growth factor receptor, whereas the nodule in the left lung had a wild-type sequence, showing that these two were genetically different cancers from one another. Thus, we demonstrate that genetic testing is useful in determining double primary lung cancer, and we herein report on this case.

Pregnancy causes alterations in bile compositions and, an increased incidence of cholelithiasis and the complications related to it. This often requires endoscopic interventions such as endoscopic retrograde cholangiopancreatography (ERCP), but the radiation exposure during the ERCP may be harmful to the fetus. We report here on a case of successful ERCP and therapeutic endoscopic intervention without fluoroscopic guidance for a pregnant woman with common bile duct stone that was complicating her biliary pancreatitis.
