However, if the remnants of the ligaments are considerably damaged, anatomical reconstructions using such remnants can be difficult. In cases such as these, tenodesis stabilization may be required. However, tenodesis stabilization often restricts the range of ankle movement. The purpose of this study was to determine the effectiveness of a new procedure that we developed to mitigate the problems associated with tenodesis stabilization procedures. We installed grafts in the original anatomical position by devising a system for positioning the drill holes in the bones so that our procedure did not restrict the range of ankle movement. A retrospective review of 37 patients (13 men, 24 women) with a mean age of 30.2 (range, 16-66) years was performed at an average of 69 (range, 47-77) months after the surgery. The average American Orthopaedic Foot and Ankle Society ankle-hindfoot score improved significantly from 65.6 (range, 47-77) points preoperatively to 98.0 (range, 87-100) points postoperatively (P < 0.001). With the number of subjects available, no significant differences were detected between the postoperative mean ranges of movement of the ankle and subtalar joints and those of the preoperative ankle. Patients who underwent anatomical tenodesis reconstructions with a free split peroneal brevis tendon showed good outcomes after a 69-month follow-up period.","PeriodicalId":46245,"journal":{"name":"KEIO JOURNAL OF MEDICINE","volume":"71 2","pages":"44-49"},"PeriodicalIF":2.0,"publicationDate":"2022-06-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"39608335","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Although the patient was successfully treated by air enema, the fever persisted. The patient was then diagnosed with incomplete Kawasaki disease based on the presence of four principal clinical features. Intravenous immunoglobulin and oral aspirin were initiated. The patient defervesced and the other symptoms subsided after the treatment. Cardiac ultrasound results showed normal coronary arteries. Because of the gastrointestinal symptoms, stool samples were cultured repeatedly, only to yield normal flora. However, serum levels of anti-Y. pseudotuberculosis-derived mitogen antibody were elevated between the 7th and 18th days of the disease, thereby confirming Y. pseudotuberculosis infection. Because Y. pseudotuberculosis infection results in various clinical manifestations, we must be aware of each symptom and address them systematically.","PeriodicalId":46245,"journal":{"name":"KEIO JOURNAL OF MEDICINE","volume":"71 2","pages":"50-52"},"PeriodicalIF":2.0,"publicationDate":"2022-06-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"39078683","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

As a result of this work, a new formula was developed for the \"boundary condition for contagion containment,\" which, based on a horizontal transmission model, gives the lower limit of sensitivity for a diagnostic test to stop the virus spreading. Two parameters are considered in the model: the level of transmission and the effective reproduction number. In example computations, the formula indicated that a one-off polymerase chain reaction-based test with a sensitivity of 85% would not be sufficient to contain highly contagious infections such as the Delta variant of SARS-CoV-2, which would likely require a sensitivity close to 100% for its containment. Furthermore, a cascade judgment system for multiple tests was proposed and examined as a form of triplet test system. This approach can enhance the accuracy of COVID-19 testing up to the minimum level needed to stop the virus spreading. The theory developed in this study will not only contribute as an academic exercise, but also be useful for making evidence-based decisions on public policy for pandemic control.","PeriodicalId":46245,"journal":{"name":"KEIO JOURNAL OF MEDICINE","volume":"71 1","pages":"13-20"},"PeriodicalIF":2.0,"publicationDate":"2022-03-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"39882033","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This effect is termed ocular neovascularization and is seen in diabetic retinopathy, age-related macular degeneration, glaucoma and retinopathy of prematurity. Current treatments for these diseases include laser photocoagulation, topical injection of corticosteroids, intravitreal injection of anti-vascular endothelial growth factor (anti-VEGF) agents and vitreoretinal surgery. Although strategies to inhibit VEGF have proved to be dramatically successful in some clinical studies, there remains the possibility of significant adverse effects regarding the blockade of crucial physiological roles of VEGF and the invasive nature of the treatments. Moreover, it is evident that other pro-angiogenic factors also play important roles in the development of these diseases, as seen in cases in which anti-VEGF therapies have failed. Therefore, new types of effective treatments are required. In this review, we discuss a promising strategy for the treatment of ocular neovascular diseases, i.e., the inhibition of hypoxia-inducible factor (HIF), a master regulator of angiogenesis. We also summarize promising recently investigated HIF inhibitors as treatments for ocular diseases. This review will facilitate more comprehensive approaches to understanding the protective aspects of HIF inhibition in the prevention of ocular diseases.","PeriodicalId":46245,"journal":{"name":"KEIO JOURNAL OF MEDICINE","volume":"71 1","pages":"1-12"},"PeriodicalIF":2.0,"publicationDate":"2022-03-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"25579582","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Previous studies have suggested the utility of chest computed tomography (CT) in the diagnosis of COVID-19 because of its high sensitivity (93%-97%), relatively simple procedure, and rapid test results. This study, performed in Japan early in the epidemic when COVID-19 prevalence was low, evaluated the diagnostic accuracy of chest CT in a population presenting with lung diseases having CT findings similar to those of COVID-19. We retrospectively included all consecutive patients (≥18 years old) presenting to the outpatient department of Keio University Hospital between March 1 and May 31, 2020, with fever and respiratory symptoms. We evaluated the performance of diagnostic CT for COVID-19 by using polymerase chain reaction (PCR) results as the reference standard. We determined the numbers of false-positive (FP) results and assessed the clinical utility using decision curve analysis. Of the 175 patients, 22 were PCR-positive. CT had a sensitivity of 68% and a specificity of 57%. Patients with FP results on CT diagnosis were mainly diagnosed with diseases mimicking COVID-19, e.g., interstitial lung disease. Decision curve analysis indicated that the clinical utility of CT imaging was limited. The diagnostic performance of CT for COVID-19 was inadequate in an area with low COVID-19 prevalence and a high prevalence of other lung diseases with chest CT findings similar to those of COVID-19. Considering this insufficient diagnostic performance, CT findings should be evaluated in the context of additional medical information to diagnose COVID-19.","PeriodicalId":46245,"journal":{"name":"KEIO JOURNAL OF MEDICINE","volume":"71 1","pages":"21-30"},"PeriodicalIF":2.0,"publicationDate":"2022-03-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"39608340","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

We herein report a rare Japanese case of rice-induced FPIES. A six-month-old, female, Japanese patient presented to the emergency room (ER) with the complaint of vomiting after feeding. Postprandial vomiting had occurred occasionally since she started ingesting solid food at the age of 5 months. Rice-induced FPIES was suspected only after the fourth ER visit based on the characteristic history of recurrent vomiting occurring 1-2 h after ingesting food containing rice. Allergen-specific IgE testing and a skin prick test with an allergen scratch extract were both negative for rice. During an oral food challenge test (OFC), vomiting was observed after the patient ingested 2 g of rice porridge. Based on the OFC results and the entire clinical course, FPIES due to rice was diagnosed. A lymphocyte stimulation test with rice revealed a significantly elevated stimulation index. Rice-induced FPIES is rarely reported among Japanese infants despite rice being a staple in the Japanese diet. The prevalence of rice-induced FPIES differs greatly among populations, suggesting a multifactorial cause associated with its development. Delays in diagnosis are common in FPIES, and our case demonstrates the importance of obtaining a dietary history of food ingested prior to symptom onset in cases of infantile repetitive vomiting.","PeriodicalId":46245,"journal":{"name":"KEIO JOURNAL OF MEDICINE","volume":"1 1","pages":""},"PeriodicalIF":2.0,"publicationDate":"2022-03-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"47103713","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, many patients experience disease progression after surgical interventions, or cannot undergo surgery as they present with unresectable disease at diagnosis. In such cases, available treatment options (local and systemic) have been limited in efficacy, which led to dismal survival rates in advanced hepatocellular carcinoma (HCC), intrahepatic colangiocarcinoma (ICC) or metastatic pancreatic ductal adenocarcinoma (PDAC). More recent developments in oncology have offered renewed hope for advanced liver cancer patients. Hypofractionated radiation has shown feasibility and promise in unresectable setting, and is now being tested in a randomized phase III trial in HCC (clinicaltrials.gov identifier NCT03186898). Antiangiogenic agents have strongly impacted the management of advanced HCC, with multiple drug options in first line setting (sorafenib, lenvatinib) and second line setting (regorafenib, cabozantinib, ramucirumab). Chemotherapy based regimens are standard of care in ICC and PDAC. Immunotherapy with anti-PD-1/PD-L1 or anti-CTLA4 antibodies has shown real potential to transform advanced HCC therapy, both in first line and second line settings. Finally, combinations of these new strategies are very attractive approaches, as they promise durable and profound responses in advanced HCC. But in order to achieve this promise more broadly, these concepts require greater understanding based on mechanistic preclinical studies and validation in correlative studies in clinical trials as a basis to establish optimal combinatorial strategies. The insights gained from this \"bench to the bedside and back\" approach raise the hope for a more efficient development of targeted agents in combination, and in earlier stages of the disease, with the goal of increasing survival in patients afflicted with this aggressive and deadly diseases.
