Background: The purpose of this study was to evaluated results of arthroscopic treatment of the traumatic recurrent unidirectional posterior subluxation. Materials and Methods: We treated twenty-seven patients who had traumatic recurrent unidirectional posterior subluxation of the shoulder by arthroscopic labral repair and posterior capsular shift and prospectively evaluated for a mean of thirty-nine months (range,24 to 85 months). Patients who had posteroinferior instability, multidirectional instability, atraumatic onset, or revision cases were excluded. There were twenty-five male and two female patients with the mean age of twenty-one years (range, 14 to 33 years). All patients were involved in sports activity. All had a significant traumatic event prior to the onset of the instability. Stability, motion, three objective measurement (UCLA, ASES, and Rowe scores) and two subjective measurements (pain and function visual analogue scale) were evaluated. Results: The most common finding in magnetic resonance image-arthrogram was separation of the posteroinferior labrum without displacement in 9 patients, In arthroscopic examination, all patients had one or more lesions in the posterior inferior labrum and capsule. The most common finding was incomplete stripping of the posterior inferior labrum (18 patients). The posteroinferior capsule subjectively appeared to be stretched in twenty-two patients. At follow-up, all patients had improved shoulder function and scores(p < 0.01). All patients had stable shoulder by subjectivel and objectivel measurements, except one patient who had recurrent subluxation. All but one patient with postoperative recurrence were able to return to their prior sports activity with little or no limitation. Twenty-four patients were graded as having more than 90％ of shoulder function. Their were twenty-one excellent, five good, and one fair UCLA. scores. Pain sore improved from 4.5 to 0.2 point(p : 0.0001). Mean loss internal rotation was one vertebral level. None had operative complications. Conclusion: In conclusion, treatment outcomes of the traumatic unidirectional recurrent posterior subluxation are consistently reliable with respect to the stability, pain relief, and functional restoration by the arthroscopic posterior capsular shift procedure.

To evaluate the bioequivalence of two venlafaxine formulations, a standard 2-way randomized cross-over study was conducted in twenty-four healthy male Korean volunteers. A single oral dose of 75 mg of test formulation Venfaxine $OR^{(R)}$ (tablet) or reference formulation Efexor $XR^{(R)}$ (capsule) was administered with one-week washout period. Plasma concentrations of venlafaxine were assayed for over a period of 72 hours with a well validated method using liquid chromatography coupled to tandem mass spectrometry (LC-MS-MS). The $mean{\pm}S.D$. of maximum concentration $(C_{max})$ and elimination half-life $(t_{1/2})$ were $64.7{\pm}28.5$ ng/mL, $9.2{\pm}3.0$ h, and $67.2{\pm}30.2$ ng/mL, $9.9{\pm}3.5$ h for test and reference formulations, respectively. Time to reach maximum concentration $(T_{max})$ expressed in median value (range), for the test and the reference, were 10 h (6-14) and 8h (4-12), respectively. Similarly, area under the plasma concentration-time curve, from time zero to last sampling time $(AUC_t)$ and from time zero to time infinity $(AUC_{inf})$, for test and reference formulations were $1185{\pm}755$, $1326{\pm}896$ and $1124{\pm}737$, $1185{\pm}755$ $ng{\cdot}h/mL$, respectively. The parametric 90% confidence intervals on the mean of the differences between the two formulations (test-reference) of the log transformed values of $AUC_t$, and $C_{max}$ were 0.9630 to 1.1383 and 0.8650 to 1.0446, respectively. The overall results indicate that the two formulations are bioequivalent and can be prescribe interchangeably.

Background: To compare the clinical outcomes of arthroscopic capsular release in patients with and without inferior capsular release for shoulder stiffness. Methods: Between January 2010 and December 2015, 39 patients who underwent arthroscopic capsular release for shoulder stiffness were enrolled and randomized into two groups. In group I, 19 patients underwent arthroscopic capsular release of the rotator interval and anterior capsule. In group II, 20 patients underwent arthroscopic capsular release of the anterior to inferior capsule, including the rotator interval. The American Shoulder and Elbow Surgeons score, Constant scoring system, Simple Shoulder Test, visual analogue scale for pain, and range of motion (ROM) were used for evaluation before surgery, at 3, 6, and 12 months after surgery and on the last follow-up. Results: Preoperative demographic data revealed no significant differences (p>0.05). The average follow-up was 16.07 months. Both groups showed significantly increased ROM at the last follow-up compared with preoperative (p<0.05). At the last follow-up, no statistical differences were found (p>0.05) between groups I and II in functional scores and ROM (forward flexion, p=0.91; side external rotation, p=0.17; abduction external rotation, p=0.72; internal rotation, p=0.61). But we found that group II gained more flexion compared to group I at 3 months and 6 months (p<0.05) after the surgery. Conclusions: Both techniques of capsular release are effective for stiffness shoulder. However, the extended inferior capsular release shows superiority in forward flexion over anterior capsular release alone during 6 months of follows-up (level of evidence: Level I, therapeutic randomized controlled trial).

In previous studies, we performed joint animal studies and clinical trials between Yonsei University and Oryza Oil & Fat Chemical Co. Ltd. We have shown that coffee bean extract has potent anti-obesity and hypotriglyceridemic activities as well as beneficial effects on body fat reduction.In this study, the effects of coffee bean extract (100 mg/capsule) on body fat reduction were evaluated in overweight/obese women (body mass index of 25~30 $kg/m^2$ or body fat > 30%) not diagnosed with any type of disease. Subjects were randomly assigned to a coffee bean extract group (n=10) or placebo group (n=10). We measured anthropometric parameters, abdominal fat distribution by computed tomography and blood components before and after the 8week intervention period. After supplementation, the coffee bean extract group showed body weight (p=0.08), body mass index (p=0.06), hip circumference (p<0.05), and upper waist circumference (p< 0.01). In addition, after 8 weeks, the coffee bean extract group showed a significant decrease in abdominal internal fat area compared to 0 weeks (0 weeks : $155.8cm^2$; 8 weeks : $145.9cm^2$, ${\Delta}$ change : $-9.9cm^2$, respectively). However, there were no significant differences in lipid profiles or serological measurements between the coffee bean extract group and placebo group. The results of our human study demonstrated that coffee bean extract supplementation for 8 weeks has beneficial effects on reducing abdominal internal fat area as well as hip and waist circumferences.

The objective of this study was to find out drug use pattern of narcotic analgesics in university hospitals in Korea. A university hospital located in Kyungbuk province was chosen for this study. The drug use pattern was analyzed in terms of ingredient, administration route, patient type, and attending department. Amount of drug usage was counted by unit dose defined by the number of ampule or vial for injectable, tablet or capsule for oral, and each for patch preparations. Result showed that 11 narcotic analgesic ingredients were used during 2007-2009, and the drug usage was increased by about 20% annually during the period. Proportion of oral preparations used for pain management was about two third of all narcotic analgesics usage and kept increasing during the period. Proportion of the drug usage for outpatients was also steadily increased. Notably, the usage of oral preparations of oxycodone, morphine, and hydromorphone was rapidly increased for the management of cancer pain while the usage of codeine and codeine-containing composite preparations for cancer pain were minimal (<10%). About 90% of all narcotic analgesics were used by physicians in Internal Department, especially in Oncology Division of the Department. These findings suggest that pain management is becoming more aggressive and in agreement with WHO's guidelines regarding selection of administration route. However, in terms of 3-step ladder for cancer pain management, the drug use pattern was not congruent to WHO's guidelines. Therefore, in conclusion, it appears that physicians need to try to be congruent to the guidelines when using narcotic analgesics for cancer pain.

This study describes the first record of Bourgelatia diducta (Nematoda: Chabertiidae) from wild boars in the Republic of Korea (=South Korea). Gastrointestinal tracts of 87 Korean wild boars (Sus scrofa coreanus) hunted in mountains in the south-western part of South Korea between 2009 and 2012 were examined for their visceral helminths. B. diducta, as identified by morphological characteristics of the head and tail, were recovered from the large intestine of 47 (54%) wild boars. The average length of adult female worms was $11.3{\pm}0.872$ mm and the thickest part of the body measured $0.54{\pm}0.04$ mm in maximum width, while those of males were $9.8{\pm}0.72$ and $0.45{\pm}0.03$ mm, respectively. The characteristic J-shaped type II ovejector was observed in females, and the type II dorsal ray with 2 rami on each side of the median fissure was uniquely seen in males. The buccal capsule was small, relatively thin-walled, cylindrical, very short, and ring-shaped. The externodorsal ray arose from a common stem with the dorsal ray. The cervical groove was absent. The anterior extremity was equipped with 20-22 external corona radiata, 4 cephalic papillae and 2 lateral amphids around the mouth. The eggs were $66.0{\times}38.9{\mu}m$ in average size. By the present study, B. diducta (Nematoda: Chabertiidae) is recorded for the first time in South Korea. Additionally, morphological characteristics and identification keys provided in the present study will be helpful in the faunistic or taxonomic studies for strongylid nematodes related.

Raillietina species are prevalent in domestic chickens (Gallus gallus domesticus) in Phayao province, northern Thailand. Their infection may cause disease and death, which affects the public health and economic situation in chicken farms. The identification of Raillietina has been based on morphology and molecular analysis. In this study, morphological observations using light (LM) and scanning electron microscopies (SEM) coupled with molecular analysis of the internal transcribed spacer 2 (ITS2) region and the nicotinamide adenine dinucleotide dehydrogenase subunit 1 (ND1) gene were employed for precise identification and phylogenetic relationship studies of Raillietina spp. Four Raillietina species, including R. echinobothrida, R. tetragona, R. cesticillus, and Raillietina sp., were recovered in domestic chickens from 4 districts in Phayao province, Thailand. LM and SEM observations revealed differences in the morphology of the scolex, position of the genital pore, number of eggs per egg capsule, and rostellar opening surface structures in all 4 species. Phylogenetic relationships were found among the phylogenetic trees obtained by the maximum likelihood and distance-based neighbor-joining methods. ITS2 and ND1 sequence data recorded from Raillietina sp. appeared to be monophyletic. The query sequences of R. echinobothrida, R. tetragona, R. cesticillus, and Raillietina sp. were separated according to the different morphological characters. This study confirmed that morphological studies combined with molecular analyses can differentiate related species within the genus Raillietina in Thailand.

Purpose: This study reports the clinical results of the arthroscopic Bankart repair in traumatic anterior instability of the shoulder with bio-knotless anchor. Materials and Methods: 21 cases of 21 patients (20 male and 1 female) were included in this study. The average age was 24.8 years old and the period from the first injury to operation was average 37.2 months. All cases had Bankart lesion and 12 cases had Hill-Sachs' lesion. The SLAP lesion was associated in 6 cases. Preoperative Rowe score was average 29.1. Arthroscopic Bankart repair with bio-knotless anchor were performed in all cases; 3 anchors at 3, 4, 5 O'clock position of the glenoid were used in 11 cases and 2 anchors at 4, 5 O'clock position were used in 10 cases. All the associated SLAP lesions were repaired arthroscopically with bio-knotless anchor. Thermal capsular shrinkage at the anterior and inferior shoulder capsule after the Bankart repair was performed in 3 cases. The average follow up period was 20.2 months. Results: The Rowe score improved to 92.8, excellent in 17 cases and good in 4 cases, at last follow up period and 20 cases had full range of motion of the shoulder. 1 case had mild limited range of motion of the shoulder (150 degrees in flexion, 60 degrees in external rotation and T12 level in internal rotation) without any problem in normal activity. The arthroscopic revision surgery of the shoulder was performed in 1 case because of multiple traumatic injuries of the shoulder with pain postoperatively. Conclusion: Arthroscopic Bankart repair with bio-knotless anchor in traumatic anterior shoulder instability is one of the good methods because of the good clinical results.
