Treatment for complete extensor tendon rupture: A case report on extensor pollicis longus tendon transfer and tenodesis procedure to radius for a patient with rheumatoid arthritis.

The complete loss of finger extension leads to significant inconvenience in daily life and often requires surgical treatment. Despite some disadvantages, the Boyes method, which uses the flexor digitorum superficialis tendon, is commonly performed for complete extensor rupture. We report the case of a 73-year-old woman living alone diagnosed with a subcutaneous rupture of all extensor tendons from the index to the little finger.

Controlling liquid-liquid phase separation of G-quadruplex-forming RNAs in a sequence-specific manner.

We constructed a minimum liquid-liquid phase separation model system to form liquid droplets using only G-quadruplex-forming oligonucleotides and R- and G-rich oligopeptides. We found that the G-quadruplex structure is an essential component for RNA to form droplets with the peptide. Based on this model system and our findings, droplet redissolution structure transition from a G-quadruplex to a duplex was achieved in a sequence-specific manner.

New body surface indexes for germinal matrix: DIP joint extension boundary line and dorsal distal interphalangeal crease.

Background: Knowledge of the proximal edge of the germinal matrix is essential to avoid injuries in the germinal matrix. The previous index such as terminal tendon insertion is not visible from the body surface. The purpose of this study was to examine the relationship between the proximal edge of the germinal matrix and the body surface indexes by ultrasonographic measurements.

Effect of Antimicrobial Prophylaxis Duration on Health Care-Associated Infections After Clean Orthopedic Surgery: A Cluster Randomized Trial.

Importance: Postoperative health care-associated infections are associated with a greater deterioration in patients' general health status and social and economic burden, with at least 1 occurring in approximately 4% of acute care hospital patients. Antimicrobial prophylaxis prevents surgical site infections in various orthopedic procedures; however, its relationship with health care-associated infections remains unknown.

Objective: To examine whether a shorter antimicrobial prophylaxis duration of less than 24 hours after surgery is not inferior to a longer duration in preventing health care-associated infections after clean orthopedic surgery.

Appropriate referral timing to specialized palliative care service: survey of bereaved families of cancer patients who died in palliative care units.

Few studies have investigated appropriate referral timing of specialized palliative care (SPC) from the perspective of cancer patients' and families' experiences. We aimed to clarify appropriate SPC referral timing for patients with advanced cancer and their families. We used data from a nationwide bereaved family survey in Japan.

Prognostic model for patients with advanced cancer using a combination of routine blood test values.

Purpose: The purpose of this study was to develop a simple prognostic model based on objective indicators alone, i.e., routine blood test data, without using any subjective variables such as patient's symptoms and physician's prediction.

RNA phase separation-mediated direction of molecular trafficking under conditions of molecular crowding.

Living cells are highly crowded with large and small biomolecules. The total concentration of biomolecules can reach 400 mg/ml, and 40% of the cell volume is occupied by biomolecules. Droplet formation in cells via liquid-liquid phase separation may play a role in controlling biochemical reactions in this complex molecular environment.

Association Between Normothermia at the End of Surgery and Postoperative Complications Following Orthopedic Surgery.

Background: Maintaining perioperative normothermia is recommended by recent guidelines for the prevention of surgical site infections (SSIs). However, the majority of supporting data originates outside the field of orthopaedic surgery.

Methods: The effect of normothermia was explored using the prospectively collected data of consecutive patients who underwent single-site surgery in 7 tertiary referral hospitals between November 2013 and July 2016.

Influences of osteoarthritis and osteoporosis on the electrical properties of human bones as in vivo electrets produced due to Wolff's law.

We characterized the electrical properties of living bone obtained from patients who had undergone total hip arthroplasty (THA) or hemiarthroplasty by means of analysis of the electrically polarized and nonpolarized bone specimens, and we discussed the role of an organic and inorganic matrix of human bone in bone piezoelectricity.We used human femoral neck bone that was harvested during THA for advanced osteoarthritis of the hip joint (OA group) and hemiarthroplasty for femoral neck fracture (FNF group). The specimens were scanned to evaluate the cancellous bone structures using micro-computed tomography, and we quantified the carbonic acid by attenuated total reflection (ATR) spectra to estimate carbonate apatite.

The role of the collaborative functions of the composite structure of organic and inorganic constituents and their influence on the electrical properties of human bone.

Background: The electrical potential, which is generated in bone by collagen displacement, has been well documented. However, the role of mineral crystals in bone piezoelectricity has not yet been elucidated.

Objective: We examined the mechanism that the composite structure of organic and inorganic constituents and their collaborative functions play an important role in the electrical properties of human bone.

Enhancement of fracture healing by electrical stimulation in the comminuted intraarticular fracture of distal radius.

Effectiveness of an alternating electric current (AC) stimulation in prevention of bone deformity for comminuted intraarticular fracture of distal radius were verified by comparing postoperative results treated with a wrist-bridging external fixator combined with or without an AC stimulator (EF and NEF, respectively), and a palmar locking plate (LP). This study evaluated 92 cases (mean age 67.9 ± 11.

Effect of reforestation on nitrogen and phosphorus dynamics in the catchment ecosystems of subtropical China: the example of the Hanjiang River basin.

Background: To enable effective management and decision making for the sustainable use of water resources, we successfully integrated factors such as dams, land use and soil properties as well as management factors in the Hanjiang River basin, a subtropical catchment of China, into the SWAT model to simulate water cycles as well as the distribution, movement, and transformations of nutrients.

Results: The accuracy of the model was validated by monitoring data over the Hanjiang River. The validated model was then used to evaluate the effects of the Reforestation of Cultivated Land (RFCL) initiative.

Clinicopathological features of malignant lymphoma in Japan: the Miyagi Study.

The Miyagi Study is an epidemiological study of malignant lymphoma, including immunological and genetic analyses, constructed by a population-based registration system covering Miyagi prefecture, Japan. A total of 1,552 newly diagnosed cases in Miyagi between 2002 and 2008 were enrolled in this study; 75% were B-cell lymphomas, 19% were T-cell and natural killer-cell (T/NK-cell) lymphomas, and 5% were Hodgkin's lymphomas. The most frequent subtype of B-cell lymphoma is diffuse large B-cell lymphoma, followed by follicular lymphoma and extranodal marginal zone lymphoma of mucosa-associated lymphoid tissue (51%, 24% and 8%, respectively).

Favorable outcome of unrelated cord blood transplantation for Philadelphia chromosome-positive acute lymphoblastic leukemia.

Philadelphia chromosome-positive acute lymphoblastic leukemia (Ph(+)ALL) is one of the highest-risk ALL groups. Whenever possible, patients with Ph(+)ALL should undergo allogeneic hematopoietic stem cell transplantation (HSCT) after induction of remission. Although unrelated cord blood transplantation (CBT) has become a common treatment in adult patients who lack a sibling donor, data on the efficacy of CBT for Ph(+)ALL are limited.

Successful allogeneic hematopoietic stem cell transplantation for aggressive NK cell leukemia.

Aggressive natural killer cell leukemia (ANKL) is a highly aggressive lymphoproliferative disease. An appropriate therapeutic strategy for ANKL remains to be established, but a few case reports have suggested that allogeneic hematopoietic stem cell transplantation (allo-HCT) can be curative. Here, we report a young woman with ANKL showing central nervous system (CNS) invasion, who has been in complete remission for more than a year after allo-HCT following two courses of intravenous chemotherapy and several rounds of intrathecal chemotherapy.

Allogeneic hematopoietic stem cell transplant following chemotherapy containing l-asparaginase as a promising treatment for patients with relapsed or refractory extranodal natural killer/T cell lymphoma, nasal type.

The prognosis of advanced extranodal NK/T cell lymphoma (ENKTL) is poor. Allogeneic hematopoietic stem cell transplant (allo-HSCT) has been suggested to be a promising treatment for this disease, but its utility has yet to be established. Here we retrospectively analyzed five cases of ENKTL treated with allo-HSCT in our institute.

As of March 2009, the patient has maintained CR for 39 months posttransplant.

Acquired hemophilia A with sigmoid colon cancer: successful treatment with rituximab followed by sigmoidectomy.

Acquired hemophilia A is a rare and potentially fatal condition of coagulopathy caused by autoantibodies against clotting factor VIII (factor VIII inhibitor). We report a case of a 63-year-old woman, who presented with a sudden onset of severe hemorrhagic tendency with exclusively prolonged activated partial thromboplastin time (APTT). She was diagnosed with acquired hemophilia A due to a decrease in factor VIII activity and a high titer of factor VIII inhibitor.

Identification of Japanese and chinese green tea cultivars by using simple sequence repeat markers to encourage proper labeling.

To identify commercial Japanese monovarietal green tea and imported green tea samples, leading Japanese cultivars were fingerprinted by using six simple sequence repeat markers analyzed by a capillary sequencer. Two well-authenticated imported Chinese monovarietal green tea samples were also fingerprinted by the same markers, one of which, was Fuyun, was a clonally propagated cultivar, and the other, Jiukengzhong, was seed-propagated. At least three markers used in this study identified 16 leading Japanese cultivars and Fuyun.
