Objectives: The purpose is to establish positive relationships between pediatric patients, their guardians, and dental workers by investigating behavioral induction methods used in pediatric treatment and to encourage active cooperation during dental treatment of pediatric patients, leading to successful treatment. Methods: From March 2023 to September 2023, general hospitals, dental hospitals, and dental clinics were randomly selected and a survey was conducted on guardians of pediatric patients and dental workers, and a total of 154 copies were used in the final analysis. Results: The difference in perception of physical restraint as a behavioral induction method was that 49 people (65.3%) perceived that guardians could only allow physical methods that would not put them in dangerous situations, while dental workers could only accept physical methods that would not put them in dangerous situations. Only 41 people (51.9%) could allow it. Conclusions In the clinic, a positive relationship must be maintained between dentists, patients, and guardians, and effective behavioral induction methods must be applied to maximize the efficiency of pediatric dental care.

PURPOSE: Preoperative assessment of the depth of invasion in the rectal wall and of lymph node metastases is very important in determining the treatment modality in rectal cancer. The purposes of study were to evaluate the accuracy of transrectal ultrasonography (TRUS) in preoperative staging of rectal cancer and to compare that accuracy with the accuracy for computed tomography (CT). METHODS: We reviewed 59 patients who were diagnosed as having rectal cancer and who had been staged by using TRUS and CT preoperatively. Ultrasonographic tumor (uT) and nodal (uN) stage and computerized tomographic tumor (cT) and nodal (cN) stage were entered into the database prospectively. The accuracy of each staging was compared with the pathologic staging. The accuracy, the sensitivity, the specificity, the positive predictive value, and the negative predictive value of each diagnostic test were calculated. Chi- square tests were conducted to identify the factors influencing the accuracy. RESULTS: The accuracies of TRUS and CT in assessing the depth of invasion were 66.1% and 62.5%, respectively. The accuracies of TRUS and CT in assessing the nodal involvement in patients treated with radical surgery were 70.4% and 63.6%, respectively. For detection of fat infiltration, the sensitivities were 97.4% for TRUS and 76.3% for CT. The specificities were 45.0% for TRUS and 55.6% for CT. The sensitivities for detection of lymph node involvement were 59.3% for TRUS and 42.9% for CT. The specificities were 81.5% for TRUS and 85.2% for CT. The gross appearance of the tumor had a significant influence on the assessment of the depth of invasion (P=0.015). In 9 out of 77 patients (11.7%) could not be performed the TRUS examination due to obstruction or the location of the tumor. CONCLUSIONS: In spite of some limitations, TRUS is considered a very useful tool in the preoperative assessment of the depth of invasion and of the lymph node involvement in rectal cancer. However, CT examination is mandatory to overcome the limitations of TRUS in the preoperative diagnosis of rectal cancers.

PURPOSE: This study evaluated the clinical outcomes of debridement arthroplasty using the posteromedial approach in elbow joints with pain and bony limitation of motion. MATERIALS AND METHODS: This study involved 16 elbows in 16 patients with pain and bony limitation of motion, which were treated by debridement arthroplasty using the posteromedial approach from March 2005 to March 2008. The mean follow up period was 27.6 (13~52) months. The clinical outcomes were analyzed using the Visual Analogue Scale(VAS) for pain scale, the preoperative and postoperative range of motion and the Mayo Elbow Performance Scores(MEPS). RESULTS: The VAS was decreased significantly from a preoperative mean of 4.5 to a postoperative mean 1.1 (p<0.001). The average arc of motion improved significantly from 61.6 (0~90)degrees preoperatively to 109.4 (80-120)degrees postoperatively (p<0.001). The MEPS also improved significantly from 59.4 to 85.6 postoperatively (p<0.001). There were no complications, such as hematoma and elbow instability. CONCLUSION: Debridement arthroplasty using the posteromedial approach is a useful surgical procedure in the elbow joint with pain and bony limitation of motion, where all compartments can be debrided, the ulnar nerve can be manipulated easily and damage to the medial collateral ligament can be minimized.

PURPOSE: Bone graft is a widely accepted surgical treatment for scaphoid nonunion. The purpose of this study was to analyze and compare the clinical outcomes of the three different bone graft techniques, Matti-Russe technique, Fisk-Fernandez technique and vascularized bone grafting. MATERIALS AND METHODS: This study involved 20 cases in 20 patients of established scaphoid nonunion who were treated with three different bone graft techniques and followed up for at least 1 year. We measured preoperative and postoperative pain, Mayo Modified Wrist Score (MMWS) and range of motion of the affected and normal side. For radiological evaluation we assessed bone union, avascular necrosis, and dorsal intercalated segment instability (DISI). RESULTS: There were no significant differences among the three groups with respect to the pain, MMWS, and range of motion. The union rate and correction of DISI also made no significant difference. The time to achieve bone union, which averaged 2.6 months was significantly decreased in the vascularized bone graft group than in the other two groups. CONCLUSION: All three methods were proper surgical procedures for treatment of scaphoid nonunion because there was no statistically significant difference in clinical and radiological outcomes. Among these three methods the vascularized bone grafting had the shortest time to achieve bone union so it could result in the fast functional recovery of the patient.

PURPOSE: Gastrointestinal stromal tumors (GISTs) are the most common mesenchymal neoplasm of the gastrointestinal (GI) tract, and account for 1% of all GI malignancies. GISTs have a highly variable clinical course, and recurrent disease sometimes develops despite curative treatment. Although there are several known risk factors for recurrence, there are few adequate treatment strategies. This study evaluated the clinical behavior and clinicopathological characteristics, and examined correlation between recurrence and the prognostic factors. METHODS: From March 1999 to December 2005, 41 patients, with GISTs confirmed by a pathologic examination after a surgical resection, were enrolled. The patients were evaluated by immunohistochemical staining for CD117, CD34 and smooth muscle actin, and were classified according to the NIH criteria. RESULTS: The mean age was 58.9 years and the GISTs were mainly located in the stomach (56%) and small bowel (32%). With a median follow-up of 17.4 months, recurrence of the disease occurred in nine (22%) patients, with the liver being the main organ involved. According to the NIH criteria, there were 2 very low risk tumors, 11 low risk, 16 intermediate, and 12 high risk diagnosed. Gender was found to have predictive value for a recurrence (P=0.05). CONCLUSION: The primary site and gender have predictive value for a recurrence. Identifying the risk factors for recurrent disease may be useful for planning follow-up schedules. Further study involving more cases and a long-term follow-up will be needed. In addition, pathologic and immunohistoche-mical studies will be required to reduce the recurrence rate after a resection and to improve the patients' outcome.

PURPOSE: With recent anorectal physiologic studies, functional etiologies of pelvic outlet obstructive disease were evaluated in detail. The current study was designed to assess the clinical and the physiologic characteristics of patients with pelvic outlet obstructive disease. METHODS: one hundred two (102) patients with pelvic outlet obstructive disease were evaluated with anorectal physiologic studies, including the colonic transit time (n=66), anorectal manometry (n=88), defecography (n=102), anal sphincter EMG (n=50), and colonoscopy or barium enema (n=77). The patients were categorized as group I (nonrelaxing puborectalis syndrome), group II (rectocele), group III (sigmoidocele), and group IV (rectoanal intussusception). The clinical and the physiologic characteristics were compared between the groups. RESULTS: The mean age was 51.9 years, and the sex ratio was 1:1.9. the populations of the groups were group I 45.1% (n=46), group II 36.3% (n=37), group III 5.9% (n=6), and group IV 9.8% (n=10). In group II and group III, co-existing etiologies were more, and the incidences of female patients was higher (P<0.05). Delayed colonic transit time was noted in 11 patients (17%). Diverticula was observed in 6 patients (8%), polyps in 12 patients (16%), and melanosis coli in 14 patients (18%). On anorectal manometry, group I showed higher maximal voluntary contraction and mean squeezing pressure than the other groups (P<0.05). On defecography, group I had a shorter perineal descent at rest and a smaller anorectal angle at push (P<0.05). CONCLUSIONS: The current study showed the clinical and the physiologic characteristics of the each functional etiology in patients with pelvic outlet obstructive disease. These results provide fundamental data for diagnosis of and tailored therapy for pelvic outlet obstructive disease.

PURPOSE: The epidermal growth factor receptor (EGFR) is a one of the transmembrane receptor proteins that play an important role in initiating tumor cell signaling and growth and is regarded as a promising target for cancer therapy. The EGFR expression rate has been reported to vary according to the detection method. The aims of this study were to evaluate the EGFR expression rate of a colorectal carcinoma by using immunohistochemical staining (IHC) and semiquantitative reverse transcription-polymerase chain reaction (RT-PCR) and to analyze the correlation between these methods. METHODS: EGFR expression was investigated in tissue sections from 33 patients with a colorectal adenocarcinoma by using IHC and semiquantitative RT-PCR. IHC was performed with antibodies in a 1:40 dilution and a 1:80 dilution. The results of the three detection methods were compared with one another. RESULTS: The mean age of the patients was 61.9+/-12.2 years, and the male-to-female ratio was 1.2:1. The EGFR expression rates were 93.9% (31/33) in IHC with a 1:40 dilution, 87.9% (29/33) in IHC with a 1:80 dilution, and 66.7% (22/33) in RT-PCR. The result of IHC with a 1:40 dilution significantly correlated with the result of IHC with a 1:80 dilution (Pearson correlation 0.684, P<0.01). There was no correlation between semiquantitative RT-PCR and IHC (1:40 dilution, 1:80 dilution). CONCLUSIONS: The EGFR expression obtained by using IHC was consistent with different antibody dilutions. The expression rate obtained by using RT-PCR was significantly lower than that obtained by using IHC, and there was no statistical correlation between the expressions of EGFR obtained by using RT-PCR and IHC. A standardization for EGFR detection methods is needed to draw any conclusion concerning their activity in colorectal cancer.

PURPOSE: Biofeedback treatment is thought to be appropriate for patients with nonrelaxing puborectalis syndrome (NRPR). The aim of this study is to analyze the physiologic characteristics and to assess the outcomes of biofeedback treatment for patients with NRPR. METHODS: Forty-six (46) patients with NRPR were evaluated with anorectal physiologic studies, including colonic transit time (n=26), anorectal manometry (n=41), defecography (n=46), anal sphincter EMG (n=28), and colonoscopy or barium enema (n=33). The treatment consisted of a training program with EMG-based biofeedback for 30 minutes once a week and routine supportive care, including Kegel practice. RESULTS: The mean age was 52.8 years, and the sex ratio was 1 male to 0.6 female. A delayed colonic transit time was noted in 5 patients (19.26%). In the NRPR group, the maximal voluntary contraction and the mean squeezing pressure were higher than they were for other patients with pelvic outlet obstructive disease. Also, the perineal descents and the dynamic change of anorectal angle were shorter. Polyps were observed in 6 patients (18.2%), melanosis coli in 4 patients (12.1%), and diverticula in 3 patients (9.1%). The rectoanal inhibitory reflex (RAIR) was negative in 3 patients (7.3%). The patients underwent a mean of 4.0 sessions, and the mean follow-up was 7.4 months. Twenty-three (23) patients (82.1%) experienced improved of symptoms or EMG findings. The patients (17.9%) who did not improve had several abnormal findings: neuro-psychologic disease with delayed colonic transit time in 2 cases, negative RAIR in 2 cases, and melanosis coli in one case. CONCLUSIONS: We think that biofeedback training is an effective treatment for patients with NRPR. In addition, several factors, such as neuro-psychologic diseases, delayed colonic transit time, negative RAIR, or melanosis coli may influence the prognosis for biofeedback treatment, so further large-scaled studies will be needed to confirm these findings.

PURPOSE: The serum levels of soluble triggering receptor expressed on myeloid cells-1 (sTREM-1) have recently been shown to be correlated highly with disease activity in patients with intestinal Behcet's disease (BD). However, it remains unclear whether sTREM-1 levels reflect endoscopic activity in intestinal BD. This study aimed to evaluate the correlation of sTREM-1 levels with endoscopic activity in intestinal BD. MATERIALS AND METHODS: A total of 84 patients with intestinal BD were enrolled. Endoscopic activity was compared with sTREM-1 levels as well as other laboratory findings, including erythrocyte sedimentation rate (ESR) and C-reactive protein (CRP). RESULTS: sTREM-1 levels were significantly increased in intestinal BD patients compared with controls (37.98+/-27.09 pg/mL vs. 16.65+/-7.76 pg/mL, p=0.002), however, there was no difference between endoscopically quiescent and active diseases (43.53+/-24.95 pg/mL vs. 42.22+/-32.68 pg/mL, p=0.819). Moreover, serum sTREM-1 levels did not differ in terms of number, shape, depth, size, margin, or type of ulcer in patients with intestinal BD. However, mean ESR and CRP levels in patients with active disease were significantly higher than those in patients with quiescent disease (p=0.001, p<0.001, respectively). In addition, endoscopic activity scores for intestinal BD were correlated significantly with both CRP levels (gamma=0.329) and ESR (gamma=0.298), but not with sTREM-1 levels (gamma=0.166). CONCLUSION: Unlike CRP levels and ESR, serum sTREM-1 levels were not correlated with endoscopic activity in patients with intestinal BD.
