BACKGROUND AND OBJECTIVES: Mucin hypersecretion is one of the main symptoms of inflammatory diseases in the respiratory tract. The authors previously reported that pleiotypic pro-inflammatory cytokine, interleukin (IL)-1beta, plays significant roles in the respiratory tract inflammation by inducing mucins (MUC2, MUC5AC, MUC8). However, the molecular mechanism for mucin hypersecretion in the respiratory tract is still unclear. MATERIALS AND METHOD: In order to understand the mechanisms of mucin hypersecretion in the airway epithelium, the differentially expressed proteins and genes in the lung mucoepidermoid carcinoma cell line (NCI-H292 cells), which were treated for 6 and 24 hours with IL-1beta (10 ng/ml), were identified using 2-dimensional polyacrylamide gel electrophoresis (2-D PAGE) proteomics and cDNA microarray analysis (8.6 K). RESULTS: In the 2-D PAGE, 8 differentially expressed proteins and 14 post-translational modification proteins were identified 6 and 24 hrs after the IL-1beta treatment. Microarray analysis identified a total of 413 genes (6.6%) in the 6-hour treatment group and 115 genes (2.0%) in the 24-hour treatment group that were regulated after the IL-1beta treatment. The differentially expressed genes that were regulated by the IL-1beta treatment were mostly found in the metabolic pathway rather than in the regulatory pathway. A comparison of the proteomic and microarray data showed that there was a large discrepancy between the protein expression and the gene expression levels. Among the genes encoding the proteins secreted in the airway, MUC5B was down-regulated but sialomucin CD 164, lysozyme, and the secretory leukocyte protease inhibitor (SLPI) were up-regulated. CONCLUSION: These results clearly show that the transcript levels have little value in predicting the extent of protein expression. Genomics and proteomics have different evaluation fields. Therefore, they may not provide all the information on the gene and protein profiles.

PURPOSE: This study was performed to assess postoperative complications and recurrence rates and to elucidate the risk factors in Crohn's disease (CD). METHODS: A retrospective review was undertaken for patients who had undergone bowel surgery at Asan Medical Center between October 1991 and June 2006. Symptomatic recurrence was defined as the presence of symptoms related to CD that was subsequently verified by radiologic or endoscopic finding. Surgical recurrence was defined as the need for repeated surgery for enteric CD. RESULTS: There were 160 patients with a mean follow up of 34 months (108 men and 52 women; mean age: 29.7+/-10.9). The most common indication for surgery was a complication of CD, such as intra-abdominal abscess (31.9%), intestinal obstruction (21.9%), and internal fistula (19.4%). Another frequent indication was medical intractability (23.8%). The types of surgical procedures were ileocolic resection (50.0%), small bowel resection (25.0%), total/subtotal colectomy (17.5%), and others. The cumulative symptomatic recurrences were 15.9% and 36.4% at 2 and 5 years, and the cumulative surgical recurrence was 13.6% at 5 years. The cumulative surgical recurrence was higher for stricturing-type CD than for penetrating-type CD (P=0.049). No other significant risk factor for recurrence was found in our study. Twenty patients (12.5%) had postoperative complications, such as intra-abdominal abscess, anastomosis leakage, obstruction, and wound infection. CONCLUSIONS: The postoperative complication and recurrence rates were acceptable. For stricturing-type Crohn's disease surgical recurrence is higher than penetrating type, but long-term follow up is needed to verify the risk factors for recurrence.

OBJECTIVE: To investigate the effect of radial extracorporeal shock wave therapy (rESWT) on hemiplegic shoulder pain (HSP) syndrome. METHODS: In this monocentric, randomized, patient-assessor blinded, placebo-controlled trial, patients with HSP were randomly divided into the rESWT (n=17) and control (n=17) groups. Treatment was administered four times a week for 2 weeks. The visual analogue scale (VAS) score and Constant-Murley score (CS) were assessed before and after treatment, and at 2 and 4 weeks. The Modified Ashworth Scale and Fugl-Meyer Assessment scores and range of motion of the shoulder were also assessed. RESULTS: VAS scores improved post-intervention and at the 2-week and 4-week follow-up in the intervention group (p<0.05). Respective differences in VAS scores between baseline and post-intervention in the intervention and control groups were -1.69±1.90 and -0.45±0.79, respectively (p<0.05), between baseline and 2-week follow-up in the intervention and control groups were -1.60±1.74 and -0.34±0.70, respectively (p<0.05), and between baseline and 4-week follow-up in the intervention and control groups were -1.61±1.73 and -0.33±0.71, respectively (p<0.05). Baseline CS improved from 19.12±11.02 to 20.88±10.37 post-intervention and to 20.41±10.82 at the 2-week follow-up only in the intervention group (p<0.05). CONCLUSION: rESWT consisting of eight sessions could be one of the effective and safe modalities for pain management in people with HSP. Further studies are needed to generalize and support these results in patients with HSP and a variety conditions, and to understand the mechanism of rESWT for treating HSP.

The fabella is a small sesamoid bone generally located in the tendon of the lateral head of the gastrocnemius behind the lateral condyle of the femur. Fabella syndrome is the occurrence of posterolateral knee pain associated with the fabella. It is a rare cause of knee pain that is often misdiagnosed. Fabella syndrome can be managed with conservative or surgical treatment. We applied radial extracorporeal shock wave therapy as a new treatment strategy for fabella syndrome and achieved a successful outcome.
