Total pharyngo-laryngo-esophagectomy (TPLE) with free jejunal transplantation (FJT) is the standard reconstructive procedure for hypopharyngeal cancer, typically utilizing the superior thyroid artery as the recipient vessel. However, patient-specific anatomical variations and comorbidities can significantly complicate this surgery. We present a unique case of a 68-year-old male with hypopharyngeal cancer who exhibited multiple challenges, including short stature (126 cm), low weight (35 kg), cervical spondylosis, and a history of vertebroplasty, highlighting the complexities inherent in such reconstructions.

A recent meta-analysis found no benefit of uric acid-lowering therapy including febuxostat on death, cardiovascular events, or renal impairment. However, there may be populations that benefit from febuxostat in reducing mortality and cerebral and cardiovascular events. The aim of the present study was to examine the clinical benefit of febuxostat in elderly patients stratified by age using Febuxostat for Cerebral and CaRdiorenovascular Events PrEvEntion StuDy (FREED) data.

Article Synopsis
  • A study analyzed the impact of weekend admissions on outcomes for patients with acute lower gastrointestinal bleeding in 49 Japanese hospitals from 2010 to 2019.
  • The findings showed no significant difference in mortality rates between weekend and weekday admissions, although weekend admissions resulted in a higher need for blood transfusions.
  • Additionally, weekend admissions led to delays in early colonoscopy and an increase in urgent CT scans, but overall mortality and other outcomes remained unaffected.

Although cardiac rehabilitation (CR) has been reported to be effective for improving the prognosis of acute myocardial infarction (AMI), more patients must participate in CR during admission and as outpatients. Factors contributing to, and countermeasures against, the low CR participation rate need to be identified. Here we describe the protocol for a study designed to evaluate the effectiveness and problems of CR for AMI from the Japanese Registry of All Cardiac and Vascular Diseases (JROAD) and the JROAD-Japanese Diagnosis Procedure Combination system (JROAD-DPC) database.

Background And Aims: Noninvasive tests (NITs) have prognostic potential, but whether NITs are comparable with liver biopsy is unclear. This study aimed to examine the prognostic accuracy of NITs for liver-related mortality (LRM) and events (LREs) in patients with biopsy-proven nonalcoholic fatty liver disease (NAFLD).

Methods: We investigated 1313 patients with NAFLD.

Although cardiovascular mortality in Japan is lower than in other industrialized countries, clinical outcomes in coronary artery disease (CAD) patients with type 2 diabetes mellitus (T2DM) remain poor despite multiple evidence-based drug therapies and interventions. We assumed that part of residual risk in these patients may be attributable to enhanced inflammation, which can be inhibited presumably by colchicine. However, dose-responsiveness of anti-inflammatory effect of colchicine has not been elucidated.

Introduction: The bleeding source of hematochezia is unknown without performing colonoscopy. We sought to identify whether colonoscopy is a risk-stratifying tool to identify etiology and predict outcomes and whether presenting symptoms can differentiate the etiologies in patients with hematochezia.

Methods: This multicenter retrospective cohort study conducted at 49 hospitals across Japan analyzed 10,342 patients admitted for outpatient-onset acute hematochezia.

Background: To examine the effect of prior use of cetuximab and neck dissection on the effectiveness of nivolumab, we conducted a large-scale subgroup analysis in Japanese patients with recurrent/metastatic head and neck cancer.

Methods: Data on the effectiveness of nivolumab were extracted from patient medical records. All patients were analyzed for effectiveness by prior cetuximab use.

Effectiveness and safety of nivolumab in patients with head and neck cancer in Japanese real-world clinical practice: a multicenter retrospective clinical study.

Int J Clin Oncol

March 2021

Department of Otolaryngology, Head and Neck Surgery, Faculty of Medicine and Graduate School of Medicine, Hokkaido University, Kita15 Nishi7, Kita-Ku, Sapporo, Hokkaido, 060-8638, Japan.

Background: To fill the data gap between clinical trials and real-world settings, this study assessed the overall effectiveness and safety of nivolumab in patients with head and neck cancer (HNC) during Japanese real-world clinical practice.

Methods: This was a multicenter, retrospective study in Japanese patients with recurrent or metastatic HNC who received nivolumab for the first time between July and December 2017. Data on the clinical use, effectiveness, and safety of nivolumab were extracted from patient medical records.

The activity of the trapezius muscle is reportedly higher than that of other neck accessory muscles under a condition of increased inspiratory pressure in the standing position. The present study aimed to compare the activity of the trapezius muscle with those of the scalene and sternocleidomastoid muscles under a condition of increased inspiratory pressure in the supine position. This study included 40 subjects, and the muscle activity was measured using surface electromyography.

Topographic analysis of the maxillary premolars relative to the maxillary sinus and the alveolar bone using cone beam computed tomography.

Oral Surg Oral Med Oral Pathol Oral Radiol

May 2017

Professor, Department of Oral and Maxillofacial Functional Rehabilitation, Graduate School of Medicine, University of the Ryukyu, Okinawa, Japan.

Objective: The purpose of the present study was to elucidate the anatomic characteristics of the maxillary premolars for the planning of dental treatment using cone beam computed tomography (CBCT).

Study Design: CBCT images were obtained for 150 maxillary premolars in 68 patients. The internal angle formed by the long axis of the maxillary premolars and the long axis of the alveolar bone was evaluated on the cross-sectional images.
