PURPOSE: To evaluate the efficacy and safety of the inferior conjunctival transposition flap for primary pterygium surgery. METHODS: This study reviewed 59 eyes in 59 patients with primary pterygium who were treated with pterygium excision and an inferior conjunctival transposition flap. The inferior conjunctival flap was obtained from lower bulbar conjunctiva and was secured with 8-0 vicryl. Patients were followed-up on the third day after surgery and then at 1, 2, 4 and 12 weeks postoperatively. RESULTS: The mean patient age was 55.6 (ranging from 34 to 74) years. The mean follow-up period was 24.9 (ranging from 12 to 46) months. During the follow-up period, the pterygium recurred in one (1.7%) of the 59 eyes. There were no severe complications except for mild congestion and hemorrhage of the conjunctival flap. CONCLUSIONS: Inferior conjunctival transposition flap technique may be considered as a safe and effective method that reduces complications and recurrences after primary pterygium excision.

Transforming growth factor-beta (TGF-beta) has been suspected as a possible gene therapy candidate for orthopedic diseases. We demonstrated that the TGF-beta gene therapy can be applicable to orthopedic patients. After transfection of TGF-beta cDNA sequence to myoblasts [C2 (280)] and fibroblasts (NIH 3T3), stable cell lines with TGF-beta mRNA expression were selected by Northern analysis. To evaluate the possibility of clinical application of these cells to orthopedic diseases, the cells were injected into rabbit achilles tendon. Intratendinous injection was done to evaluate the viability of the cells and to determine the optimal concentration for in vivo expression. At 6 weeks after injection, the injected tendon was thickened with newly formed collagen. The results from this experiment indicates that these cells survived and stimulated matrix formation in rabbit achilles tendon. We concluded that TGF-beta cDNA transfected cells can be useful in the evaluation of TGF-beta biology in vivo.

Purpose: Developmental endothelial locus-1 (DEL-1) plays a role in regulating neutrophil migration within the periodontium. The objective of this study was to evaluate the levels of DEL-1 in saliva and gingival crevicular fluid (GCF), as well as the number of neutrophils in patients with periodontitis. Methods: Forty systemically healthy, non-smoking periodontitis patients participated in this study. Clinical periodontal parameters, including the plaque index, probing pocket depth (PPD), clinical attachment level, bleeding on probing, modified sulcular bleeding index, and marginal bone level, were measured. Levels of DEL-1, interleukin (IL)-1β, IL-6, and IL-8 in unstimulated saliva samples, as well as DEL-1 in the GCF of 3 teeth from each participant, were assessed. Neutrophil counts in oral rinse and GCF samples were recorded. Spearman correlation coefficients were used to examine the correlation between protein levels, clinical parameters, and neutrophil quantities. Participants were divided into 2 age groups (those under 50 years and those 50 years or older) in order to investigate potential age-related differences. Results: DEL-1 levels in the GCF showed a negative relationship with PPD (sum). Neutrophils in oral rinse samples were positively correlated with PPD, IL-8, and IL-1β levels. Neutrophils in GCF exhibited a positive correlation with PPD (sum). Salivary DEL-1 levels showed correlations with IL-8 and IL-1β, but not with the clinical parameters of periodontitis. Conclusions The negative relationship observed between PPD and GCF DEL-1 levels is consistent with the proposed protective role of DEL-1.

Since Endoscopic ultrasound (EUS) was introduced in the 1980s, EUS has evolved from a diagnostic tool to a therapeutic modality for patients with pancreatic neoplasms. Traditionally, treatment policy of pancreatic benign neoplasms (PBN) has been a dichotomous approach to observation or surgery. However, EUS guided treatment provides an alternative option with minimally invasiveness for patients with PBN. This review aimed to provide the role of EUS guided treatment for PBN.

BACKGROUND: In this study, the optimal effect-site concentration of remifentanil for blunting hemodynamic responses to endotracheal intubation during total intravenous anesthesia using propofol were evaluated. METHODS: 137 ASA class I and II patients, aged 18-60 years, were randomly allocated to one of six groups according to the effect-site concentration of remifentanil. Remifentanil was then infused at a target effect-site concentration of 0, 1, 2, 3, 4 or 6 ng/ml in groups R0, R1, R2, R3, R4 and R6, respectively. Anesthesia was induced with propofol infusion at a target effect-site concentration of 4microgram/ml endotracheal intubation was performed 5 minutes after remifentanil administration. Blood pressure (BP), heart rate (HR) and cardiac index (CI) were recorded at the baseline and then every 30 seconds until 3 minutes after intubation. RESULTS: BP and HR in groups R0, R1 and R2 increased significantly after intubation when compared with the baseline values. The CI in group R0 also increased significantly after intubation when compared with the baseline values. Incidences of hypertension and hypotension were 50% and 5% in R0, 32% and 14% in R1, 18% and 32% in R2, 10% and 48% in R3, 8% and 54% in R4, and 0% and 81% in R6. There were also 2 cases in which the mean blood pressure was less than 50 mmHg in group R6. CONCLUSIONS: We suggest that the optimal target effect-site concentrations of remifentanil for blunting hemodynamic responses to endotracheal intubation are 3 or 4 ng/ml during total intravenous anesthesia using propofol at an effect-site concentration of 4microgram/ml.
