BACKGROUND/AIMS: Irritable bowel syndrome (IBS) is a functional gastrointestinal (GI) tract disorder that has heterogeneous clinical presentations such as abdominal pain, diarrhea, constipation, and abdominal distension. It is known that several mechanisms are involved in the pathogenesis of IBS. Probiotics may target one or more pathophysiologic pathways in IBS and may improve the symptoms of IBS. However, the results of studies about probiotics on IBS are controversial. Therefore, the aim of this study was to evaluate the effect of probiotics on GI symptoms and intestinal gas volume changes in patients with IBS. METHODS: Forty patients were randomly allocated to be treated with medilac DS(R) (Bacillus subtilis, Streptococcus faecium) (n=20) or placebo (n=20) in a double-blind, prospective manner. The change in intestinal gas volume and symptom scores after 4-week treatment were evaluated for the efficacy. RESULTS: There was no significant difference in bloating, frequency of gas expulsion, frequency of defecation, and hardness of stool before and after the treatment. However, the severity of abdominal pain and the frequency of abdominal pain decreased significantly in medilac DS(R)group (2.4+/-1.3 cm/day -> 1.6+/-1.6 cm/day, 1.7+/-1.3/day -> 1.0+/-1.0/day) (p=0.044, p=0.038), but not in placebo group (2.1+/-2.0 cm/day -> 1.8+/-2.1 cm/day, 1.3+/-1.2/day -> 1.4+/-1.9/day). In both groups, intestinal gas volume at baseline, after 2-week treatment, and after 4-week treatment did not show significant change. Medilac DS(R)was well tolerated without adverse events. CONCLUSIONS: Medilac DS(R)is a safe and useful probiotic agent for the treatment of abdominal pain in patients with IBS.

BACKGROUND: To evaluate the clinical results and operation technique of arthroscopic repair of combined Bankart and superior labrum anterior to posterior (SLAP) lesions, all of which had an anterior-inferior Bankart lesion that continued superiorly to include separation of the biceps anchor in the patients presenting recurrent shoulder dislocations. METHODS: From May 2003 to January 2006, we reviewed 15 cases with combined Bankart and SLAP lesions among 62 patients with recurrent shoulder dislocations who underwent arthroscopic repair. The average age at surgery was 24.2 years (range, 16 to 38 years), with an average follow-up period of 15 months (range, 13 to 28 months). During the operation, we repaired the unstable SLAP lesion first with absorbable suture anchors and then also repaired Bankart lesion from the inferior to superior fashion. We analyzed the preoperative and postoperative results by visual analogue scale (VAS) for pain, the range of motion, American Shoulder and Elbow Surgeon (ASES) and Rowe shoulder scoring systems. We compared the results with the isolated Bankart lesion. RESULTS: VAS for pain was decreased from preoperative 4.9 to postoperative 1.9. Mean ASES and Rowe shoulder scores were improved from preoperative 56.4 and 33.7 to postoperative 91.8 and 94.1, respectively. There were no specific complication and no significant limitation of motion more than 10 degree at final follow-up. We found the range of motions after the arthroscopic repair in combined lesions were gained more slowly than in patients with isolated Bankart lesions. CONCLUSIONS: In recurrent dislocation of the shoulder with combined Bankart and SLAP lesion, arthroscopic repair using absorbable suture anchors produced favorable clinical results. Although it has technical difficulty, the concomitant unstable SLAP lesion should be repaired in a manner that stabilizes the glenohumeral joint, as the Bankart lesion can be repaired if the unstable SLAP lesion is repaired first.

BACKGROUND: Cortical suspensory femoral fixation is commonly performed for graft fixation to the femur in anterior cruciate ligament (ACL) reconstruction using hamstring tendons. The purpose of this study was to compare graft healing in the femoral tunnel, implant-related failure, and clinical results between fixed- and adjustable-length loop devices in outside-in ACL reconstruction. METHODS: A total of 109 patients who underwent ACL reconstruction using the outside-in technique from December 2010 to July 2014 were included. For femoral graft fixation, a fixed-length loop device was used in 48 patients (fixed-loop group) and an adjustable-length loop device was used in 61 patients (adjustable-loop group). For evaluation of graft healing in the femoral tunnel, magnetic resonance imaging was performed at postoperative 6 months and the signal-to-noise ratios (SNRs) of the tendon graft and tendon-bone interface in the femoral bone tunnel were evaluated. The presence of synovial fluid was evaluated to determine loop lengthening at the femoral tunnel exit. Clinical results assessed using International Knee Documentation Committee score, Tegner-Lysholm Knee Scoring scale, and knee instability tests were compared between groups. RESULTS: The SNRs of the tendon graft and tendon-bone interface were not statistically different between groups. The presence of synovial fluid at the femoral exit showed no statistical difference between groups. Clinical results were not significantly different between groups. CONCLUSIONS: The adjustable-length loop device provided comparable graft healing, implant-related failure, and clinical results with the fixed-length loop device, allowing adaptation of the graft to the different tunnel lengths. Therefore, it could be effectively used with an adjustment according to the femoral tunnel length.

BACKGROUND: Nonunion of lateral humeral condyle fracture causes cubitus valgus deformity. Although corrective osteotomy or osteosynthesis can be considered, there are controversies regarding its treatment. To evaluate elbow joint biomechanics in non-united lateral humeral condyle fractures, we analyzed the motion of elbow joint and pseudo-joint via in vivo three-dimensional (3D) kinematics, using 3D images obtained by computed tomography (CT) scan. METHODS: Eight non-united lateral humeral condyle fractures with cubitus valgus and 8 normal elbows were evaluated in this study. CT scan was performed at 3 different elbow positions (full flexion, 90° flexion and full extension). With bone surface model, 3D elbow motion was reconstructed. We calculated the axis of rotation in both the normal and non-united joints, as well as the rotational movement of the ulno-humeral joint and pseudo-joint of non-united lateral condyle in 3D space from full extension to full flexion. RESULTS: Ulno-humeral joint moved to the varus on the coronal plane during flexion, 25.45° in the non-united cubitus valgus group and −2.03° in normal group, with statistically significant difference. Moreover, it moved to rotate externally on the axial plane −26.75° in the non-united cubitus valgus group and −3.09° in the normal group, with statistical significance. Movement of the pseudo-joint of fragment of lateral condyle showed irregular pattern. CONCLUSIONS: The non-united cubitus valgus group moved to the varus with external rotation during elbow flexion. The pseudo-joint showed a diverse and irregular motion. In vivo 3D motion analysis for the non-united cubitus valgus could be helpful to evaluate its kinematics.

STUDY DESIGN: Retrospective study. OBJECTIVES: To identify risk factors for infection after spinal surgery. SUMMARY OF LITERATURE REVIEW: Infection after spinal surgery is relatively uncommon. However, such infections cause serious consequences and increased costs and sequelae. Risk factors for infection after spinal surgery include a posterior approach, instrumentation, the use of an allogenic bone graft, transfusion, and a long operating time. Patient-related factors include diabetes and obesity. MATERIALS AND METHODS: From January 2009 to December 2013, 350 patients who underwent surgery at our hospital due to spinal disease, including 10 patients with a postoperative spinal infection, were evaluated. We investigated patients' age, gender, morbidity due to diabetes mellitus, body mass index, level of surgery, approach, location, instrumentation, and operation type. RESULTS: Ten of the 350 patients developed a spinal infection after surgery. The proportion of diabetic patients among the infected patients was higher than among the non-infected patients, although the difference was not statistically significant. Additionally, the proportion of diabetic patients with hemoglobin A1c levels greater than 7.0% was higher among the infected patients. Operating time, the surgical approach, drain tube insertion, transfusion, and the use of an allogenic bone graft were not significantly different between the infected and non-infected patient groups. CONCLUSIONS: Uncontrolled diabetes is the most important risk factor for the development of spinal infection after surgery. Therefore, in order to prevent infection after surgery, blood glucose should be controlled before surgery.

The terms "gastrointestinal stromal tumor" (GIST) have been applied to mesenchymal tumos that represent neither typical leiomyoma nor schwannoma. The majority of GISTs are Located in the stomach and small intestine, and only 4% of GISTs are found in duodenum. The most important characteristic is their indolent, slow-growing nature, rendering the most common definitions of malignancy invalid and inapplicable. Clinical and pathological criteria to differentiate benign from malignant GISTs are not well established. Tumor size and mitoic activity are commonly considered as important features, allowing for the prediction of biological behaviour and outcome. The case of a 87-year-old male patient who was presented with melena and acute anemia is herein reported. Esophagogastroduodenoscopy and computed tomography of the abdomen revealed two submucosal tumors in the stomach and duodenum. Histological and immunohistochemical studies on the surgical resection specimen revealed a gastrointestinal stromal tumor of an uncommiteed type, with no evidence of increased mitotic activity. The patient was treated with local excision of the tumors and is now in a favorable state.

BACKGROUND: Recently, CD34 antigen expressed on hematopoietic stem cells which is not detected on non-Hodgkin lymphoma (NHL), multiple myeloma and most solid tumors, is identified. In autologous bone marrow transplantation (BMT), positive selection of CD34+ cells may be used to provide hematopoietic stem cells capable of engraftment but depleted of tumor cells. And it can be used to depletion of T lymphocytes to prevent the graft versus host disease (GVHD) in allogeneic BMT. So we performed this study to evaluate the efficacy of purification of CD34+ stem cells with CEPRATE SC Stem Cell Concentration System (CellPro Inc.) and to assess the influence of CD34+ stem cells on engraftment. METHODS: Peripheral blood stem cells were mobilized with cyclophosphamide (except one patient with malignant lymphoma) and G-CSF and harvested using CS-3000 (Fenwall). CD34+ stem cells counted by FACScan (Becton-Dickinson). The conditioning regimens were ICE (Ifosphamide/Carboplatin/Etoposide) in breast cancer, high dose melphalan in multiple myeloma, BEAC (BCNU/Etoposide/Ara-C/Cyclophosphamide) in NHL, TBI (total body irradiation) with cyclophosphamide in acute lymphocytic leukemia (ALL) and busulfan with cyclophosphamide in myelodysplastic syndrome (MDS). We used G-CSF (10 microgram/kg) after transplantation in all patients. RESULTS: Eleven patients, six with high risk or metastatic breast cancer, one with refractory multiple myeloma, one with acute lymphocytic leukemia (transformed from lymphoblasticlymphoma), two with relapsed malignant lymphoma, one with myelodysplastic syndrome (HLA one-locus mismatched allogeneic BMT case, for T lymphocyte depletion) were treated. Hematopoietic stem cells were harvested from autologous peripheral blood in all patients except one patient with MDS whose stem cells were harvested from allogeneic bone marrow. Median duration and number of peripheral blood stem cell (PBSC) harvest were 15 days (13~22) and 3 times (2~8), respectively. The mean number of total stem cells and CD34+ stem cells harvested per pheresis were 204.8 (17.4~797.9)x106/kg and 3.0 (0.3~11.9)x106/kg, respectively. The mean efficacy of CD34+ hematopoietic stem cell selection by CEPRATE SC Stem Cell Concentration System was 47.7% (1.4~99.0%). The number of infused CD34+ stem cells per patient ranged from 0.34 to 4.8x106/kg (mean 2.3x106/kg). After transplantation, the median day of achieving granulocyte counts of >0.5x109/L was 10.5 days and platelet counts of >50x109/L was 14 days. CONCLUSION: CD34+ stem cells separated with CEPRATE SC Stem Cell Concentration System provided reliable and timely hematopoietic reconstitution.
