Growth and development of the gel permeation chromatography method for examining cellulose nitrate throughout galleries and museums.
ater or equal to 4.0° was detected as threshold for an increased risk of abnormal side-to-side difference in postoperative anterior tibial translation in patients who underwent primary ACL reconstruction. This confirms that soft tissue slopes have an impact on the outcomes after reconstructive surgery. Level of evidence III.PURPOSE The high incidence of metachronous colorectal tumours in patients with hereditary non-polyposis colorectal cancer (HNPCC) encourages extended resection (ER); however, the optimal surgical approach remains unclear. We evaluated the incidences of metachronous colorectal neoplasms following curative colorectal cancer segmental resection (SR) vs ER in patients with HNPCC and investigated patients' oncologic outcomes according to surgical modality and mismatch repair status. METHODS We retrospectively investigated medical records of patients with HNPCC (per the Amsterdam II criteria) treated for primary colon cancer at our institution between 2001 and 2017. All patients underwent intensive endoscopic surveillance. RESULTS We included 87 patients (36 who underwent SR and 51 who underwent ER). The cumulative incidence of metachronous adenoma was higher in the SR group. Capsazepine TRP Channel antagonist One patient in the SR group (2.8%) and 3 in the ER group (5.9%) developed metachronous colon cancer; the difference was not significant (P = 0.693). Four patients in the SR group (11.1%) and 1 in the ER group (2.0%) developed distant recurrences; again, the difference was not significant (P = 0.155). Moreover, no significant differences were observed in the 5-year overall survival rates of patients in the SR and ER groups (88.2% vs 95.5%, P = 0.446); the same was true for 5-year disease-free survival rates (79.5% vs 91.0%, P = 0.147). CONCLUSION The incidence of metachronous cancer was not significantly different between the ER and SR groups; however, that of cumulative metachronous adenoma was higher in the SR group. Hence, intensive surveillance colonoscopy may be sufficient for patients with HNPCC after non-extensive colon resection.PURPOSE A modified endoscopic mucosal resection (EMR) technique, Tip-in EMR, was recently introduced to enhance the complete resection of colorectal neoplasia (CRN). We aimed to evaluate the feasibility of Tip-in EMR for flat CRNs. METHODS From January to September 2018, conventional or Tip-in EMR was consecutively performed for 112 flat CRNs ≥ 10 mm in diameter. Tip-in EMR was performed when en bloc snaring was impossible with conventional EMR or when a lesion was inadequately lifted owing to a previous forceps biopsy. We retrospectively collected the clinical, procedural, and histologic data of the conventional and Tip-in EMR groups and compared the en bloc resection rate, complete resection rate, and complications between the two groups. RESULTS Among 112 flat CRNs of 80 patients, conventional EMR and Tip-in EMR were performed for 74 and 38 lesions, respectively. The median lesion size was 12 (10-27) mm. Tip-in EMR was superior to conventional EMR in terms of en bloc resection (94.7% vs. 77.0%, p = 0.018) and histologic complete resection (76.3% vs. 54.1%, p = 0.022). There was no difference in postprocedural bleeding between the two groups; however, overall adverse events, including bleeding and postpolypectomy electrocoagulation syndrome, were more frequent in the Tip-in EMR group. CONCLUSIONS Tip-in EMR is a feasible technique for flat colorectal lesions ≥ 10 mm and is superior to conventional EMR with respect to en bloc and complete resection rates. The safety profiles of Tip-in EMR and conventional EMR should be compared via large-scale prospective studies.Felty's syndrome (FS) is a deforming disease, characterized by the triad of rheumatoid arthritis (RA), neutropenia, and splenomegaly. Currently, FS patients are treated mainly with immunosuppressants, such as methotrexate and glucocorticoids, which however are not suitable to some patients and may cause severe side effects. Here we report a clinical FS case that was treated with Tocilizumab (TCZ) successfully. The patient had symmetrical swelling and pain of multiple joints, deformity of elbow joints with obvious morning stiffness. Joint color Doppler ultrasound showed synovial hyperplasia and bone erosion of wrist and proximal interphalangeal joints and CT scan suggested splenomegaly. Further examination showed neutropenia and anemia, a high titer of anti-cyclic citrullinated peptide antibody, rheumatoid factor and anti-nuclear antibodies, positive p-ANCA, and elevated IgA and IgG. After treating with TCZ, the patient has been relieved of clinical symptoms. His spleen has recovered to normal size. The absolute neutrophil count (ANC) tended to be stable, and joint erosion did not deteriorate. We have reviewed the literatures on FS treatment with biological agents and found only a few reports using TNF-α antagonist and rituximab treating FS, but none with TCZ. So, it is the first time to report a successful FS case treated with TCZ. This case suggests that the TCZ may be a new choice for FS treatment, under the condition of closely monitoring the ANC.Familial Mediterranean fever (FMF) is the most common monogenic autoinflammatory disease manifesting with phenotypic heterogeneity. The phenotype-genotype correlation is not established clearly yet. Furthermore, some comorbidities such as vasculitis and inflammatory arthritis may accompany FMF. Herein, we aimed to define phenotype-genotype correlation and comorbid diseases of children with FMF. The medical records of 1687 children diagnosed and followed up as FMF were reviewed retrospectively. Disease severity was assessed by PRAS score. A total of 1687 children (841 girls, 846 boys) were involved in the study. The mean ± standard deviation of current age, age at symptom onset, and age at diagnosis were 13.1 ± 5.4, 5.4 ± 4, and 8 ± 4.2 years, respectively. Median (min-max) follow-up period was 3 (0.5-18) years. Among them, 118 (7%) patients had at least one concomitant disease and 72% of them were carrying at least one M694V mutation. Patients with a concomitant disease expressed a more severe course of disease when compared to ones without a concomitant disease (23.
