BACKGROUND Familial idiopathic basal ganglia calcification (FIBGC) is a rare autosomal dominant disorder that causes bilateral calcification of the basal ganglia and/or cerebellar dentate nucleus, among other locations. CASE SUMMARY The aim of this study is to report 10 cases of FIBGC observed in a single family. Seven patients showed calcification on their computed tomography scan, and all of these patients carried the SLC20A2 mutation. However, individuals without the mutation did not show calcification. Three patients among the 7 with calcification were symptomatic, while the remaining 4 patients were asymptomatic. Additionally, we longitudinally observed 10 subjects for ten years. In this paper, we mainly focus on the clinical course and neuroradiological findings in the proband and her *** The accumulation of more case reports and further studies related to the manifestation of FIBGC are needed.

AIM To investigate the post-colonoscopy colorectal cancer(PCCRC) rate for high-definition(HD) colonoscopy compared with that for standard-definition colonoscopy reported *** Using medical records at Sano Hospital(SH) and Dokkyo Medical University Koshigaya Hospital(DMUKH), we retrospectively obtained data on consecutive patients diagnosed as having CRC between January 2010 andDecember 2015. The definition of PCCRC was diagnosis of CRC between 7 and 36 mo after initial high-definition colonoscopy that had detected no cancer, and patients were divided into a PCCRC group and a non-PCCRC group. The primary outcome was the rate of PCCRC for HD colonoscopy. The secondary outcomes were factors associated with PCCRC and possible reason for occurrence of early and advanced *** Among 892 CRC patients, 11 were diagnosed as having PCCRC and 881 had non-PCCRC. The PCCRC rate was 1.7%(8/471) at SH and 0.7%(3/421) at DMUKH. In comparison with the non-PCCRC group, the PCCRC group had a significantly higher preponderance of smaller tumors(39 mm vs 19 mm, P = 0.002), a shallower invasion depth(T1 rate, 25.4% vs 63.6%, P = 0.01), a non-polypoid macroscopic appearance(39.0% vs 85.7%, P = 0.02) and an earlier stage(59.7% vs 90.9%, P = 0.03). Possible reasons for PCCRC were "missed or new" in 9 patients(82%), "incomplete resection" in 1(9%), and "inadequate examination'" in 1(9%). Among 9 "missed or new" PCCRC, the leading cause was non-polypoid shape for early PCCRC and blinded location for advanced *** The PCCRC rate for HD colonoscopy was 0.7%-1.7%, being lower than that for standard-definition colonoscopy(1.8%-9.0%) reported previously employing the same methodology.

Epithelial cell adhesion efficacy of a novel peptide identified by panning on a smooth titanium surface

引用

International Journal of Oral Science 2018年第3期10卷 174-181页

作者： Hidemichi Kihara David M.Kim Masazumi Nagai Toshiki Nojiri Shigemi Nagai Chia-Yu Chen Cliff Lee wataru Hatakeyama Hisatomo Kondo John Da Silva Harvard School of Dental Medicine BostonMAUSA School of Dental Medicine Iwate Medical UniversityIwateJapan University of California San FranciscoCAUSA

Epithelial attachment via the basal lamina on the tooth surface provides an important structural defence mechanism against bacterial invasion in combating periodontal disease. However, when considering dental implants, strong epithelial attachment does not exist throughout the titanium-soft tissue interface, making soft tissues more susceptible to peri-implant disease. This study introduced a novel synthetic peptide(A10) to enhance epithelial attachment. A10 was identified from a bacterial peptide display library and synthesized. A10 and protease-activated receptor 4-activating peptide(PAR4-AP, positive control) were immobilized on commercially pure titanium. The peptide-treated titanium showed high epithelial cell migration ability during incubation in platelet-rich plasma. We confirmed the development of dense and expanded BL(stained by Ln5) with pericellular junctions(stained by ZO1) on the peptide-treated titanium surface. In an adhesion assay of epithelial cells on A10-treated titanium, PAR4-AP-treated titanium, bovine root and non-treated titanium, A10-treated titanium and PAR4-AP-treated titanium showed significantly stronger adhesion than non-treated titanium. PAR4-AP-treated titanium showed significantly higher inflammatory cytokine release than non-treated titanium. There was no significant difference in inflammatory cytokine release between A10-treated and non-treated titanium. These results indicated that A10 could induce the adhesion and migration of epithelial cells with low inflammatory cytokine release. This novel peptide has a potentially useful application that could improve clinical outcomes with titanium implants and abutments by reducing or preventing peri-implant disease.

Current management of patients with hepatocellular carcinoma

引用

World Journal of Hepatology 2015年第15期7卷 1913-1920页

作者： Tatsuo Kanda Sadahisa Ogasawara Tetsuhiro Chiba Yuki Haga Masao omata Osamu Yokosuka Department of Gastroenterology and Nephrology Graduate School of Medicine Chiba University Yamanashi Hospitals (Central and Kita) Organization University of Tokyo Hongo

The current management therapies for hepatocellular carcinoma(HCC) patients are discussed in this review. Despite the development of new therapies, HCC remains a "difficult to treat" cancer because HCC typically occurs in advanced liver disease or hepatic cirrhosis. The progression of multistep and multicentric HCC hampers the prevention of the recurrence of HCC. Many HCC patients are treated with surgical resection and radiofrequency ablation(RFA), although these modalities should be considered in only selected cases with a certain HCC number and size. Although there is a shortage of grafts, liver transplantation has the highest survival rates for HCC. Several modalities are salvage treatments; however, intensive care in combination with other modalities or in combination with surgical resection or RFA might offer a better prognosis. Sorafenib is useful for patients with advanced HCC. In the near future, HCC treatment will include stronger molecular targeted drugs, which will have greater potency and fewer adverse events. Further studies will be ongoing.

Systematic review of bone marrow stimulation for osteochondral lesion of talus-evaluation for level and quality of clinical studies

引用

World Journal of Orthopedics 2017年第12期8卷 956-963页

作者： Youichi Yasui Laura Ramponi Dexter Seow Eoghan T Hurley wataru Miyamoto Yoshiharu Shimozono John G Kennedy 2~(nd) Department of Orthopaedic Surgery Teikyo University School of Medicine Hospital for Special Surgery New York 2~(nd) Rizzoli Orthopaedic Institute 2~(nd) Royal College of Surgeons in Ireland Department of Orthopaedic Surgery Teikyo University School of Medicine

AIM To clarify the quality of the studies indicating lesion size and/or containment as prognostic indicators of bone marrow stimulation(BMS) for osteochondral lesions of the talus(OLT). METHODS Two reviewers searched the Pub Med/MEDLINE and EMBASE databases using specific terms on March 2015 in accordance with the Preferred Reporting Items for Systemic Reviews and Meta-Analyses guidelines. Predetermined variables were extracted for all the included studies. Level of evidence(LOE) was determined using previously published criteria by the Journal of Bone and Joint Surgery and methodological quality of evidence (MQOE) was evaluated using the Modified Coleman Methodology Score. RESULTS This review included 22 studies. Overall, 21 of the 22(95.5%) included studies were level Ⅳ or level Ⅲ evidences. The remaining study was a level Ⅱ evidence. MQOE analysis revealed 14 of the 22(63.6%) included studies having fair quality, 7(31.8%) studies having poor quality and only 1 study having excellent quality. CONCLUSION The evidence supporting the use of lesion size and containment as prognostic indicators of BMS for OLTs has been shown to be of low quality.
