Surgical Treatment of Calcaneal Avulsion Fracture in Elderly Patients Using Cannulated Cancellous Screws and Titanium Wire.

Avulsion fractures of the calcaneus are relatively uncommon and are seen most frequently in elderly or osteoporotic patients. A surgical method that avoids displacement of the avulsed fragment after fixation has not been developed. We report the cases of 3 patients (a 73-year-old male, an 85-year-old male, and an 81-year-old female) treated by open reduction and internal fixation using titanium wire and cannulated cancellous screws. The posterior approach was used by way of a vertical midline incision. The fracture was fixed with 2 screws, and then a titanium wire was passed through the holes of the cannulated screws. A small incision on the lateral side of planter was added for the exit and return of the wire. The wire knot was bent inside the proximal Achilles tendon bursa in 2 patients and was directed to the plantar side in 1 to avoid irritation. Bony union was achieved without repeat displacement of the fragment in all 3 patients. Normal ankle function was restored, and the patients recovered the activities of daily living almost to the original level. Although an additional plantar incision is required, this surgical technique provides strong internal fixation.

Use of tocilizumab to treat arthritis associated with mixed connective tissue disease complicated by ovarian teratoma: a case report.

Mixed connective tissue disease (MCTD) is characterized by mixed features of systemic lupus erythematosus, systemic sclerosis, and polymyositis/dermatomyositis and is rare in children. Here, we report a case of MCTD in a 10-year-old girl who presented at our hospital with arthralgia, Raynaud's phenomenon, and fatigue. Blood tests were positive for anti-U1-ribonucleoprotein (RNP) antibodies and for rheumatoid factors (RFs) IgG-RF and anti-galactose-deficient IgG. Levels of myogenic enzymes and hypergammaglobulinemia were elevated. Macrophages were prominent in bone marrow, with scattered phagocytic macrophages. MCTD was diagnosed based on the patient's symptoms and laboratory findings. Methylprednisolone pulse therapy combined with oral tacrolimus was administered, which led to resolution of symptoms. Three months after pulse therapy, arthralgia worsened and methotrexate was administered. Arthralgia improved but did not resolve. Magnetic resonance imaging performed to investigate the hip pain revealed a mature ovarian teratoma, which was surgically removed. Because the pain persisted and interfered with her daily life, she was treated with tocilizumab for joint pain relief, which decreased the pain level. Tocilizumab is a candidate for additional treatment of juvenile idiopathic arthritis-like arthritis associated with childhood-onset MCTD.

Highly sensitive detection of Epstein-Barr virus-infected cells by EBER flow FISH.

When Epstein-Barr virus (EBV) infection is suspected, identification of infected cells is important to understand the pathogenesis, determinine the treatment strategy, and predict the prognosis. We used the PrimeFlow™ RNA Assay Kit with a probe to detect EBV-encoded small RNAs (EBERs) and multiple surface markers, to identify EBV-infected cells by flow cytometry. We analyzed a total of 24 patients [11 with chronic active EBV disease (CAEBV), 3 with hydroa vacciniforme lymphoproliferative disorder, 2 with X-linked lymphoproliferative disease type 1 (XLP1), 2 with EBV-associated hemophagocytic lymphohistiocytosis, and 6 with posttransplant lymphoproliferative disorder (PTLD)]. We compared infected cells using conventional quantitative PCR methods and confirmed that infected cell types were identical in most patients. Patients with CAEBV had widespread infection in T and NK cells, but a small amount of B cells were also infected, and infection in patients with XLP1 and PTLD was not limited to B cells. EBV-associated diseases are believed to be complex pathologies caused by EBV infecting a variety of cells other than B cells. We also demonstrated that infected cells were positive for HLA-DR in patients with CAEBV. EBER flow FISH can identify EBV-infected cells with high sensitivity and is useful for elucidating the pathogenesis.

Clinical Course and Cytokine Profile of Systemic Juvenile Idiopathic Arthritis in a Patient with Trisomy 21.

Trisomy 21 (Down syndrome) is sometimes complicated by congenital heart disease; however, comorbid type I diabetes mellitus and diseases involving autoantibodies, such as Hashimoto disease and Graves disease, are not uncommon. Autoinflammatory diseases such as Kawasaki disease and systemic juvenile idiopathic arthritis are rare. We report a rare case of trisomy 21 with systemic juvenile idiopathic arthritis that responded well to the initial course of methylprednisolone pulse therapy but flared up and was complicated by macrophage activation syndrome (MAS). Subsequent methylprednisolone pulse therapy and cyclosporine resolved this condition. Cytokines were analyzed at several time points during the clinical course and revealed that interleukin-18, interleukin-6, and chemokine ligand 9 levels were elevated at MAS onset in the present patient, even though clinical symptoms had abated. Thus, early analysis of cytokine profiles should be performed to assess MAS risk and determine treatment intensity, even in T21 patients.

Characteristics of the Japanese Diet Described in Epidemiologic Publications: A Qualitative Systematic Review.

CONTEXT: International interest in the Japanese diet has grown in recent years. OBJECTIVE: The aim of this systematic review was to evaluate and organize the Japanese diet and dietary characteristics from an epidemiological perspective, mainly focusing on the nutritional and dietary elements. DATA SOURCES: PubMed, Web of Science, Japan Medical Abstracts Society, JDream III, and CiNii databases were searched. STUDY SELECTION: The eligibility criteria included research with an epidemiological study design that was either cross-sectional, cohort, or case-control-based that defined the dietary patterns of the Japanese diet using dietary pattern analysis. A total of 39 research articles that described the Japanese diet were included. DATA EXTRACTION: The data that were extracted included the following: implementing country, location, study design, participant characteristics, key outcomes, methods used in the analysis of dietary patterns, and descriptions of the Japanese diet. DATA SYNTHESIS: As a result of the systematic review analyzing the descriptions of the Japanese diet from 39 selected articles, we were able to aggregate the descriptions into 16 categories from 33 factors. After performing a content analysis using a further aggregation of categories, we found that the top three applicable categories were soybeans/soybean-derived products, seafood, and vegetables; these were followed by rice and miso soup. CONCLUSION: The Japanese dietary content was found to be diverse based on an examination of epidemiological studies; however, we were able to aggregate the content into 16 categories. The Japanese diet is considered to be a dietary pattern that contains a combination of factors: the dietary staple, side dishes, and soup.

How Evacuees Obtained Health Care Information After the Great East Japan Earthquake: A Qualitative Interview Study.

OBJECTIVE: To explore how evacuees obtained health care information at their evacuation destinations after the Great East Japan Earthquake. METHODS: We conducted semi-structured interviews of 11 evacuees who moved to City A in Kyoto Prefecture following the Great East Japan Earthquake. The interviews explored how the evacuees obtained health care information, including the main factors of influence. The interviews were transcribed and analyzed to identify trends by using the constant comparative method. RESULTS: Four categories emerged from 6 concepts. Mother-children evacuees and family evacuees tended to obtain health care information in different ways. Family evacuees had moved as a family unit and had obtained their health care information from local neighbors. Mother-children evacuees were mothers who had moved with their children, leaving behind other family members. These evacuees tended to obtain information from other mother-children evacuees. At the time of evacuation, we found 2 factors, emotions and systems, influencing how mother-children evacuees obtained health care information. CONCLUSIONS: We found 2 different ways of obtaining health care information among mother-children evacuees and other evacuees. At the time of evacuation, 2 factors, emotions and systems, influenced how mother-children evacuees obtained health care information. Community-building support should be a priority from an early stage after a disaster for health care management. (Disaster Med Public Health Preparedness. 2017;11:729-734).
