Salivary gland intraductal carcinoma (IDC) is a complex ductal neoplasm surrounded by layer of myoepithelial cells. Recent insights have shown that there are three different types: intercalated duct-like, with frequent NCOA4-RET fusions; apocrine, salivary duct carcinoma-like mutations; and mixed duct-like/apocrine, RET fusions, including TRIM27-RET. In addition, an oncocytic IDC has been described, but it remains unclear whether represents fourth variant or simply metaplasia another type....
Pancreatic hamartoma is a rare tumor, and its characteristic histopathologic features have not yet been fully evaluated. In this study, we collected 9 cases of pancreatic to elucidate distinctive that can serve establish tumor as clear disease entity thus formulate useful criteria for tumor. The comprised 4 men 5 women with mean age 62.7 years. average diameter was 3.3 cm. All patients underwent surgical treatment, none showed any recurrence postoperatively. Macroscopically, hamartomas were...
Secretory carcinoma of the skin is a rare adnexal carcinoma, which morphologically and immunohistochemically identical to secretory breast associated with presence t (12;15) translocation, resulting in ETV6-NTRK3 gene fusion. Nineteen cases primary cutaneous have been previously published literature. In this study, we describe 6 new skin. The study group consisted 5 female patients 1 male patient, ranging age from 57 98 years (mean: 74.2, median: 74). Locations included axilla (2), neck,...
The purpose of this study was to investigate whether postoperative combined anteversion (CA) can be kept within the safe zone while using cementless total hip arthroplasty (THA) operative technique which prepares socket first for developmental dysplasia (DDH), by estimating metaphyseal fit stem preoperative three-dimensional (3D) computerized planning and adjusting a navigation system that considers CA. Our subjects were 65 patients (65 hips) had undergone THA DDH could observed 1 year or...
Porous tantalum is a biomaterial newly applied for artificial joints. We present here 5-years follow-up report of multicenter clinical trial total hip arthroplasties (THA) with porous modular acetabular component (modular PTC).Study participants received 82 hips in 79 cases, 61.2 months on average. Age at operation was 60.9 years. Clinical results were evaluated using Merle d'Aubigne Postel score. Presence implant loosening, periacetabular radiolucency, osteolysis, and gap filling examined...
A retrospective cohort study.To investigate the risk factors for postoperative delirium after spine surgery, excluding older age, which has already been established as a strong factor.More than 30 have reported making it challenging to identify should be prioritized. We hypothesized that could not prioritized date because factor of age is very and influenced other factors. To eliminate influence we performed an age-matched group comparison analysis investigation factors.This study involved...

BACKGROUND CD5‐positive (CD5 + ) diffuse large B‐cell lymphoma (DLBCL) is characterized by frequent central nervous system recurrence and a predominant activated B‐cell‐like nature. Primary DLBCL in sanctuary sites (DLBCL‐SS) also demonstrates these features, >70% of patients harbor myeloid differentiation primary response 88 ( MYD88 (L265P) CD79B mutations. The objective the current study was to elucidate possible relationship between CD5 DLBCL‐SS. METHODS MYD88, CD79B, CD79A , caspase...
Aims Low‐grade intraductal carcinoma (LG‐IDC) is a clinically indolent malignant tumour of the salivary glands. Because its rarity, histological variants LG‐IDC have not been well characterised. Herein, we describe five cases with prominent oncocytic change in major Methods and results We examined cases, three males two females (mean age = 63 years), change. The sites affected by were parotid submandibular lesions macroscopically unilocular or multilocular cysts solid arising from cyst wall....
Abstract Periprosthetic bone loss due to adaptive remodeling is an important unresolved issue in cementless total hip arthroplasty (THA). The use of porous tantalum on the proximal surface femoral stem expected decrease postoperative around prosthesis through early fixation. We conducted a multicenter randomized controlled study determine if could reduce periprosthetic after THA. From October 2012 September 2014, 118 patients (mean age, 61.5 years; 107 females and 11 males) were...
In periacetabular osteotomy for the treatment of developmental dysplasia hip, impairments in ADL due to limitations hip flexion can occur when anterior displacement is added lateral order obtain sufficient femoral head coverage. This study was conducted determine, by range motion (ROM) simulation based on CT images, minimum angle and internal rotation at 90° that necessary avoid after eccentric rotational acetabular (ERAO) estimate angles coverage plain radiography enable above flexion.Of 47...
Extracorporeal cardiopulmonary resuscitation (ECPR) is being used increasingly in the emergency and critical care field Japan. A major complication of ECPR bleeding; however, optimal initial heparin dose activated coagulation time (ACT) remain unknown. The aim this study was to assess appropriateness our anticoagulation protocol.We retrospectively evaluated dose, ACT value, incidence bleeding thrombotic complications post-cardiopulmonary arrest patients who received a fixed, body...
Abstract Aim of the study To compare outcomes after computer-assisted peri-acetabular osteotomy (PAO) and conventional PAO performed for hip dysplasia (DDH). Methods Ninety-one patients (98 hips) were enrolled in this study. In each case, DDH was treated with either PAO, which angle direction determined by intra-operative X-ray examination, or used 3D navigation system. Forty hips underwent 58 PAO. Results Japanese Orthopaedic Association scores improved significantly from 70.0 points...
Several studies have reported the prognostic factors for soft tissue sarcoma. Although serum lactate dehydrogenase (LDH) levels are associated with poor prognosis in several types of cancer, their role sarcomas remains unclear. Therefore, present study evaluated association between LDH and clinical characteristics A total 103 patients diagnosed primary sarcoma 2003 2019 were retrospectively examined, at first visit analysed. In high-grade sarcoma, survival characteristics, including...
Several investigators have emphasized the positive effect of hypothermia therapy on patients who suffered from cardiac arrest. Salvaging circulatory collapse is a pivotal task, but it unclear whether additional can practically contribute to an improvement in neurological outcome.Since December 2005, our hospital has been using therapy. Forty-six comatose after recovery spontaneous circulation were consecutively enrolled present study. Twenty-five received and 21 did not because they treated...
Disseminated intravascular coagulation (DIC) is often associated with infection and a poor outcome. In this study, useful markers for predicting outcomes were examined.The frequency of DIC organ failure, hemostatic prospectively evaluated in 242 patients infections.Seventy-seven diagnosed DIC, 36 whom recovered from the condition. The rate or resolution was highest sepsis lowest respiratory infections. Mortality tended to be high score, sepsis-related failure assessment (SOFA) prothrombin...
