New Surgical Instruction Method for Homium Laser Enucleation of the Prostate, "Hand-Grab Navigated Technique," to Shorten the Learning Curve: The Results of Multicenter Analysis.

Objectives: To introduce a new surgical mentorship, the "hand-grab navigated technique," to shorten the learning curve for Holmium laser enucleation of the prostate.

Methods: Patients with benign prostatic hyperplasia were managed at six institutions with Holmium laser enucleation of the prostate. An analysis was done in the 200 of these patients (the set of first 20 patients treated with Holmium laser enucleation of the prostate by 10 surgeons) who were sorted into two groups depending on the surgeon's instructional group.

Purpose: To identify incidence and risk factors of recurrence after discontinuation of successful antimuscarinic therapy in patients with overactive bladder (OAB).

Lateral meniscocapsular separation in patients with tibial plateau fractures: detection with magnetic resonance imaging.

Objective: This study aimed to retrospectively evaluate magnetic resonance imaging findings for the detection of lateral meniscocapsular separation (LMCS) in patients with tibial plateau fractures. We hypothesize that patients with LMCS have greater perimeniscal abnormal signal or greater distance between the lateral meniscus (LM) and the lateral collateral ligament (LCL) than patients without LMCS.

Methods: The study group included 16 patients with LMCS and 11 patients with normal LMCS who underwent surgery due to tibial plateau fracture.

Effects of antibiotic growth promoter and characterization of ecological succession in Swine gut microbiota.

Ever since the ban on antibiotic growth promoters (AGPs), the livestock death rate has increased owing to pathogenic bacterial infections. There is a need of developing AGP alternatives; however, the mechanisms by which AGP enhances livestock growth performance are not clearly understood. In this study, we fed 3-week-old swine for 9 weeks with and without AGPs containing chlortetracycline, sulfathiazole, and penicillin to investigate the effects of AGPs on swine gut microbiota.

Intercellular adhesion molecule-1 (ICAM-1, CD54) is increased in adhesive capsulitis.

Background: The purpose of this study was to investigate the presence of intercellular adhesion molecule-1 (ICAM-1) in shoulders with adhesive capsulitis ("frozen shoulder").

Methods: Glenohumeral capsular tissue was obtained from twenty-six patients (seventeen with adhesive capsulitis and nine controls), and ICAM-1 was evaluated with use of oligonucleotide arrays, real-time reverse transcription-polymerase chain reaction (RT-PCR), and immunohistochemistry. ICAM-1 was also evaluated in synovial fluid with use of western blotting (six patients with adhesive capsulitis and two controls) and in peripheral blood with use of an enzyme-linked immunosorbent assay (ELISA) (thirty-two patients with adhesive capsulitis, twenty with diabetes mellitus, and fourteen controls).

Malignant inflammatory myofibroblastic tumor of the bladder with rapid progression.

A 71-year-old man was referred for painless hematuria and a bladder tumor. Cystoscopy and computed tomography revealed a 3-cm oval nodular mass on the left lateral side of the bladder. The patient underwent a complete transurethral resection of the lesion and histology showed a proliferation of atypical spindle cells with inflammation consistent with a myofibroblastic tumor.

Estimation of maximal oxygen uptake without exercise testing in Korean healthy adult workers.

Maximal oxygen uptake is generally accepted as the most valid and reliable index of cardiorespiratory fitness and functional aerobic capacity. The exercise test for measuring maximal oxygen uptake is unsuitable for screening tests in public heath examinations, because of the potential risks of exercise exertion and time demands. We designed this study to determine whether work-related physical activity is a potential predictor of maximal oxygen uptake, and to develop a maximal oxygen uptake equation using a non-exercise regression model for the cardiorespiratory fitness test in Korean adult workers.

Learning curve of office-based ultrasonography for rotator cuff tendons tears.

Purpose: To compare the accuracy of ultrasonography and MR arthrography (MRA) imaging in detecting of rotator cuff tears with arthroscopic finding used as the reference standard.

Methods: The ultrasonography and MRA findings of 51 shoulders that underwent the arthroscopic surgery were prospectively analysed. Two orthopaedic doctors independently performed ultrasonography and interpreted the findings at the office.

A new technique of arthroscopic fixation using double anchors for SLAP lesions.

Purpose: The aim of this study was to evaluate the clinical and structural outcome of the new fixation technique of type-II SLAP repair using double anchors compared with conventional method.

Methods: Twenty-eight patients with 29 shoulders, who were followed up for at least 1 year after surgery, were enrolled. Fourteen shoulders were treated using the new technique (group 1), and 15 shoulders using the conventional technique (group 2).

In vivo strain analysis of the intact supraspinatus tendon by ultrasound speckles tracking imaging.

Limited data exist regarding why delaminated tears occur within the rotator cuff tendon, and no general agreement exists on how to handle this complicated tear. To analyze in vivo intratendinous strain of the supraspinatus tendon, the superficial, middle, and deep regions were marked with speckles using 2D speckle tracking echocardiography (2D STE) of 15 shoulders. The displacement and the strain of each speckle during isotonic and isometric shoulder motion were evaluated.

Background: Robotic surgery for rectal cancer may be a way to overcome the limitations of laparoscopic surgery. However, totally robotic surgery for rectal cancer is still technically challenging. This report describes the technical details and outcomes of totally robotic rectal surgery.

Agreements between different methods of gap balance estimation in cruciate-retaining total knee arthroplasty.

The authors investigated the agreements between three different methods of estimating gap balance in cruciate-retaining (CR) total knee arthroplasty (TKA) with the use of a subvastus approach. One hundred consecutive CR TKAs were prospectively included in this study. After completing soft tissue release and bone cutting for CR TKA, flexion-extension gap balance was assessed using a distractor, spacer blocks, and trial components.

With the exception of flexion gap tightness, which is common in cruciate-retaining (CR) total knee arthroplasty (TKA), the risk factors of flexion gap tightness have not been described. This retrospective study characterized factors that are associated with flexion gap tightness in CR TKA. Data on 203 consecutive knees that underwent CR TKA were reviewed.

The purpose of this study was to determine the thigh girth cutoff limit for the subvastus approach in primary total knee arthroplasty. One hundred forty-three consecutive total knee arthroplasties were done using the subvastus approach by one surgeon. The larger the thigh girth, the higher the risk for inability to evert the patella.

The passive compression test: a new clinical test for superior labral tears of the shoulder.

Background: Even though there are several physical tests available for superior labrum anterior posterior lesions, there have been very few reports on their accuracy, and none can be regarded as completely predictive for the presence of a superior labrum anterior posterior lesion in the shoulder joint.

Hypothesis: This new clinical test is a useful and accurate technique for detecting superior labral tears in the shoulder joint.

Study Design: Cohort study (diagnosis); Level of evidence, 2.
