Cr(VI) is a known toxic heavy metal which is found frequently in many industrial sites. Contaminates soil and ground water with Cr(VI) is a big enviromental concern due to the high toxicity. Permeable Reactive Barrier(PRB)is an innovative remedial technology intensively studied and developed recenty. The most popular PRB material is zero-valent iron which is environmentally favorable and cheap. Scrapped steels and precleaned scrapped steels were tested in this study for Cr(VI). Scrapped steels were precleaned wuth detergent, acetone, hexane.The precleaned scrapped steel showed relatively high reactivity for Cr(VI). The results indicate that the scrapped steel could be used as PRB material after proper pretreatments.

Objectives : To observe the effect of acupuncture and nerve block combination treatment on adhesive capsulitis patients. Metbods : 59 voluntary patients were randomly assigned to acupuncture treatment group(E group ,n=22), nerve block treatment group(W group, n=17) and acupuncture and nerve block combination treatment group(EW grouP, n=20). The E group received acupuncture treatment on LI15, TE_(14), GB_(21) and Master Dong's acupuncture points, Shin-gwan and Gyun-joong, twice a week for 4 weeks. The W group received suprascapular nerve block, subacromial injection and trigger point injection twice a week for 4 weeks. The EW group received the same treatment as the W group and after 5minutes of rest, successively received the treatment identical to that of E group. AU three groups were instructed to practice groups were instructed to practice self exercise during their daily lives. Evaluations were made before treatment and after 1, 2, 3 and 4week treatment. Constant Shoulder Assessment(CSA), Shoulder Pain and Disability Index(SPADI), Range of Motion(ROM), the patient's treatment satisfaction measured by Visual Analogue Scale(VAS) and Digital Infrared Thermographic Imaging(DITI) were used as assessment tools. The obtained data were analyzed and compared. Results : The E group showed significant improvement(p<0.05) on CSA, SPADI, VAS and DITI. As for ROM, Adduction and Extension improved significantly(p<0.05). The W group showed significant improvement(p<0.05) on CSA, SPADI, VAS and DITI. As for ROM, Abduction and Extension improved significantly. The EW group showed significant improvement(p<0.05) on CSA, SPADI and VAS. As for ROM, Adduction, Abduction, Extension and Flexion improved significantly. The improvement of CSA, VAS and Abduction ROM in the EW group was significant1y(P<0.05) superior compared to the groups treated with single type of treatment. Conclusion : It is suggested that acupuncture and nerve block combination treatment for adhesive capsulitis patients is more effective than the two single treatments. Through further studies, the acupuncture and nerve block combination treatment model may be developed into East-West Collaboration Model in treating adhesive capsulitis.

Background: Non-adherence to oral maintenance therapy in adolescents with inflammatory bowel disease (IBD) is a significant healthcare problem. Knowledge of the prescribed medication can increase medication adherence. We aimed to investigate the relationship between medication adherence and disease-related knowledge of pediatric and adolescent patients with IBD. Methods: We conducted a “pop quiz” to investigate the disease-related knowledge of pediatric patients with IBD who were followed-up at our institution and reviewed their medical records, including data on sex, diagnosis, age at diagnosis, and disease duration. Medication adherence was evaluated by the doctor in charge, and ≥ 80% of patients constituted the “good adherence group.” Results: Of 93 patients, 59 (63.4%) were males, and 78 (83.9%) had Crohn's disease. The mean age at diagnosis was 13.8 ± 2.8 years; mean follow-up duration, 4.8 ± 3.4 years; and mean patient age, 18.6 ± 3.7 years. Only 65 patients (69.9%) knew the exact name of the medication they were currently taking, and 34 (36.6%) knew the correct dose. Only 15 patients (16.1%) knew the name of the medications they were previously taking. A total of 64 patients (66.8%) showed an adherence rate of 80% for the weekly prescribed oral medication. The patients in the poor adherence group were significantly older than those in the good adherence group (P = 0.035). The number of hospitalizations per year was statistically higher in the good adherence group (P = 0.024). The proportion of patients who knew the names of the medications they were previously taking and were aware of the side effects of the medications was significantly higher in the good adherence group (P = 0.008 and P = 0.020, respectively). Conclusion: Adolescent IBD patients have lower oral medication adherence. Knowledge of the prescribed medications taken previously, and the adverse effects of these medications are associated with good adherence. IBD specialists should educate the patients regarding the disease and about their medication.

Objective: Adequate methods of combining T2-weighted imaging (T2WI) and diffusion-weighted imaging (DWI) to assess complete response (CR) to chemoradiotherapy (CRT) for rectal cancer are obscure. We aimed to determine an algorithm for combining T2WI and DWI to optimally suggest CR on MRI using visual assessment. Materials and Methods: We included 376 patients (male:female, 256:120; mean age ± standard deviation, 59.7 ± 11.1 years) who had undergone long-course CRT for rectal cancer and both pre- and post-CRT high-resolution rectal MRI during 2017– 2018. Two experienced radiologists independently evaluated whether a tumor signal was absent, representing CR, on both post-CRT T2WI and DWI, and whether the pre-treatment DWI showed homogeneous hyperintensity throughout the lesion. Algorithms for combining T2WI and DWI were as follows: ‘AND,’ if both showed CR; ‘OR,’ if any one showed CR; and ‘conditional OR,’ if T2WI showed CR or DWI showed CR after the pre-treatment DWI showed homogeneous hyperintensity. Their efficacies for diagnosing pathologic CR (pCR) were determined in comparison with T2WI alone. Results: Sixty-nine patients (18.4%) had pCR. AND had a lower sensitivity without statistical significance (vs. 62.3% [43/69]; 59.4% [41/69], p = 0.500) and a significantly higher specificity (vs. 87.0% [267/307]; 90.2% [277/307], p = 0.002) than those of T2WI. Both OR and conditional OR combinations resulted in a large increase in sensitivity (vs. 62.3% [43/69]; 81.2% [56/69], p < 0.001; and 73.9% [51/69], p = 0.008, respectively) and a large decrease in specificity (vs. 87.0% [267/307]; 57.0% [175/307], p < 0.001; and 69.1% [212/307], p < 0.001, respectively) as compared with T2WI, ultimately creating additional false interpretations of CR more frequently than additional identification of patients with pCR. Conclusion: AND combination of T2WI and DWI is an appropriate strategy for suggesting CR using visual assessment of MRI after CRT for rectal cancer.

Choledochal cyst(congenital cytic dilatation of the common bile duct) is a reletively rare malformation. Recently, improved diagnostic techniques are demonstrating an increasing number of unsuspected choledochal cysts. The authors evaluated six cases of surgically proven choledochal cyst diagnosed by radiological modalities. The results are follows : 1. All patients were female and age distribution was from 7 months to 19 years. 2. The most frequent symptoms were abdominal pain and palpable abdominal mass, which was followed by jaundice. 3. Diagnostic nodalities were intravenous cholangiography(1 case), upper G-I series(4 cases), ultrasonography(4 cases), 99mTc-HIDA cholescintigraphy(2 cases) and abdominal computed tomography(1 case). 4. All cases were type Ⅰof Powell classification, morphologically. 5. Findings on ultrasonography(4 cases) included a large cystic mass in the porta hepatis separate from the gallbladder ; a dilated common hepatic or common bile duct entering directly into the cyst ; normal or dilated gallbladder ; and choledocholithiasis. 6. 99mTc-HIDA cholescintigraphy(2 cases) confirmed the diagnosis of choledochal cyst by demonstrating filling of the cyst with stasis and delayed intestinal activity. 7. The accurate preoperative diagnosis of choledochal cyst, made by imaging modalities such as ultrasonography, 99mTc-HIDA cholescintigraphy and abdominal computed tomotraphy, obviated invasive studies such as intravenous cholangiography, arteriography, endoscopic retrograde cholangiopancreatography and percutaneous transhepatic cholangiography.

Subcutaneous panniculitis-like T-cell lymphoma(SPTL) is a rare cytotoxic T-cell lymphoma of the skin, which preferentially infiltrates subcutaneous tissue. In the World Health Organization(WHO) classification of T-cell and natural killer cell lymphoma it is listed as an example of extranodal lymphoma. We report a case of SPTL in a 31-year-old man, who presented with fever, night sweats, fatigue and three, tender, erythematous, indurated, subcutaneous plaques on the trunk. Typical histologic features of panniculitic infiltration with rimming of fat cells and sparing of the dermis and epidermis were seen. The immunophenotypic studies showed a cytotoxic T-cell phenotype by CD3+, CD8+, TIA-1+, CD20- and CD56-. In situ hybridization for Epstein-Ban virus-encoded RNA was negative.

<P>To determine the impact of treatment protocols on the outcome of central nervous system germ cell tumors (CNS-GCTs), we reviewed the medical records of 53 patients who received front-line chemotherapy from September 1997 to September 2006. Pure germinoma, normal alpha-fetoprotein level and beta-human chorionic gonadotropin level <50 mIU/mL were regarded as low-risk features and the others as high-risk. Patients from different time periods were divided into 3 groups according to the chemotherapy protocols. Group 1 (n=19) received 4 cycles of chemotherapy comprising cisplatin, etoposide and bleomycin. Group 2 (n=16) and group 3 (n=18) received 4 cycles of chemotherapy with cisplatin, etoposide, cyclophosphamide and vincristine in the former and with carboplatin, etoposide, cyclophosphamide and bleomycin in the latter. In group 2 and group 3, high-risk patients received double doses of cisplatin, carboplatin and cyclophosphamide. Radiotherapy was given after chemotherapy according to the clinical requirements. The event-free survivals of groups 1, 2, and 3 were 67.0%, 93.8%, and 100%, respectively (group 1 vs. 2, <I>P</I>=0.06; group 2 vs. 3, <I>P</I>=0.29; group 1 vs. 3, <I>P</I>=0.02). Our data suggest that risk-adapted intensive chemotherapy may improve the outcome of patients with malignant CNS-GCTs.</P>
