Primary small bowel mesentery de-differentiated liposarcoma causing torsion with no recurrence for 5 years: A case report and review of the literature.

Rationale: Liposarcoma (LPS) is a rare malignant soft-tissue tumor. Management of LPS is relatively difficult, because there are no characteristic symptoms, or biomarkers, nor any established effective treatment. Hence, the report of the accumulation of each LPS case is necessary.

Superficial non-ampullary duodenal cancer identified by small-bowel capsule endoscopy: a case report (with video).

Herein, we report for the first time a case of a surficial superficial non-ampullary duodenal cancer causing obscure intestinal bleeding that was identified by small-bowel capsule endoscopy and treated by endoscopic mucosal resection. A 73-year-old man underwent upper gastrointestinal endoscopy to identify the cause of anemia. Although conventional duodenoscopy revealed a flat, elevated 5-mm lesion with a central recess and "milk-white mucosa" at the inferior duodenal angulus, capsule endoscopy revealed a white nodular 5-mm lesion with central recess at the duodenum slightly to the anal side from the major duodenal papilla.

Arthroscopic Superior Capsule Reconstruction Can Eliminate Pseudoparalysis in Patients With Irreparable Rotator Cuff Tears.

Background: Patients with pseudoparalysis and irreparable rotator cuff tears have very poor function. The authors developed a superior capsule reconstruction (SCR) technique for irreparable rotator cuff tears that restores shoulder stability and muscle balance, improving shoulder function and relieving pain.

Purpose: To evaluate whether arthroscopic SCR reversed preoperative pseudoparalysis in patients with irreparable rotator cuff tears.

A rare case of primary small bowel de-differentiated liposarcoma causing intussusception: A case report.

Rationale: Liposarcoma (LPS) is a relatively rare malignant soft tissue tumor. Management of LPS including diagnosis is difficult, because it has no characteristic symptoms and no established effective treatment. Herein we reported an extremely rare case of intussusception induced by primary small bowel LPS.

Dysbiosis-Associated Polyposis of the Colon-Cap Polyposis.

Cap polyposis is a rare gastrointestinal disease characterized by multiple inflammatory polyps located between the distal colon and the rectum. Despite the lack of clarity regarding its pathogenesis, mucosal prolapse, chronic inflammatory responses, and infection are considered key contributors to the development of this disease entity. Although it is now generally accepted that dysbiosis of gut microbiota is associated with intestinal and extra-intestinal diseases, alterations of intestinal microbiota have been poorly defined in cap polyposis.

Return to Sports and Physical Work After Arthroscopic Superior Capsule Reconstruction Among Patients With Irreparable Rotator Cuff Tears.

Background: Although sports participation and heavy physical work can contribute to rotator cuff tears, many patients expect to return to these activities after surgery; however, irreparable rotator cuff tears can preclude this outcome. A new surgical treatment-arthroscopic superior capsule reconstruction (SCR)-restores shoulder stability and muscle balance in patients with irreparable rotator cuff tears; consequently, it improves shoulder function and relieves pain.

Purpose: To evaluate the rates of return to sports and physical work among patients treated with arthroscopic SCR.

Alleviating Pancreatic Cancer-Associated Pain Using Endoscopic Ultrasound-Guided Neurolysis.

The most common symptom in patients with advanced pancreatic cancer is abdominal pain. This has traditionally been treated with nonsteroidal anti-inflammatory drugs and opioid analgesics. However, these treatments result in inadequate pain control or drug-related adverse effects in some patients.

Giant GIST of the stomach: a successful case of safe resection with preoperative simulation using three-dimensional CT angiography: Case report.

Rationale: We report a very rare case of safely resectable giant gastrointestinal stromal tumor (GIST) with preoperative three-dimensional computed tomography (3D-CT) angiography in spite of no neoadjuvant treatment.

Patient's Concern: A 71-year-old woman presented to our hospital with an abdominal giant tumor. As this giant tumor could not be accurately diagnosed by preoperative investigation, we had to perform her surgical treatment without neoadjuvant treatment.

Does the Novel Potassium-Competitive Acid Blocker Vonoprazan Cause More Hypergastrinemia than Conventional Proton Pump Inhibitors? A Multicenter Prospective Cross-Sectional Study.

Background/aim: The long-term administration of proton pump inhibitors (PPIs) is useful for preventing recurrent reflux esophagitis. On the other hand, several adverse reactions, such as an increase in the blood gastrin level, have been reported. The aim of the present study was to examine the increase in the blood gastrin level due to the long-term administration of conventional PPIs compared with vonoprazan.

Vonoprazan, a Novel Potassium-Competitive Acid Blocker, Should Be Used for the Helicobacter pylori Eradication Therapy as First Choice: A Large Sample Study of Vonoprazan in Real World Compared with Our Randomized Control Trial Using Second-Generation Proton Pump Inhibitors for Helicobacter pylori Eradication Therapy.

Background/aims: Phase III study demonstrated that vonoprazan-based Helicobacter pylori eradication therapy achieved higher eradication rate compared with lansoprazole. However, there is no study that evaluated the efficacy of vonoprazan in a large sample in real world. We investigated the eradication rate and safety of vonoprazan-based eradication therapy compared with our randomized control trial using second-generation proton pump inhibitor (PPIs).

A Social Program for the Early Detection of Pancreatic Cancer: The Kishiwada Katsuragi Project.

Objectives: The early-stage pancreatic cancer (e-PC; stage I/II) detection rate is quite low at approximately 25%. The aim of this study was to evaluate the feasibility of a social program (the Kishiwada Katsuragi project) wherein our hospital, which specializes in PC, and primary care medical offices (PMOs) used clinical findings to detect e-PC.

Methods: Patients with a score of ≥2 points on clinical findings were enrolled: symptoms of abdominal pain/back pain (1 point), new-onset diabetes (1 point), high amylase (AMY) and/or pancreaitc AMY (P-AMY) (1 point), high carbohydrate antigen 19-9 (1 point), and ultrasonography (US) findings including direct (e.

Little Leaguer's Shoulder Can Cause Severe Three-Dimensional Humeral Deformity.

We analyzed three-dimensional (3D) humeral deformity (valgus-varus, flexion-extension, and rotational deformation) after little leaguer's shoulder using 3D computed tomography in a 15-year-old male baseball player. Humeral retroversion was increased by 27.1° on the dominant side compared with the nondominant side.

Therapy of gastroesophageal reflux disease and functional dyspepsia overlaps with symptoms after usual-dose proton pump inhibitor: Acotiamide plus usual-dose proton pump inhibitor versus double-dose proton pump inhibitor.

Background And Aim: Gastroesophageal reflux disease (GERD) and functional dyspepsia (FD) often coexist or overlap. In this study, the efficacy of acotiamide in combination with a standard dose of rabeprazole for GERD and FD was compared with that of a double dose of rabeprazole.

Methods: Patients with overlap between GERD and FD experiencing heartburn and epigastric fullness symptoms after standard-dose proton pump inhibitor (PPI) for ≥ 8 weeks were randomized into two groups and received either acotiamide 300 mg/day + rabeprazole 10 mg/day or rabeprazole 20 mg/day for 4 weeks.

Comparison of plantar pressure distribution in patients with hallux valgus and healthy matched controls.

Background: Detailed information regarding differences in plantar pressure distribution between hallux valgus and healthy feet is unavailable. The purposes of the present study were to clarify the characteristics of the plantar pressure distribution in patients with hallux valgus compared with healthy matched controls and to determine whether hallux valgus leads to dysfunction of the great toe during walking.

Methods: The study consisted of 25 patients with symptomatic moderate-to-severe hallux valgus (HV group) and 13 healthy matched volunteers (C group) without hallux valgus.

Bridging suture makes consistent and secure fixation in double-row rotator cuff repair.

Background: Inconsistent tension distribution may decrease the biomechanical properties of the rotator cuff tendon after double-row repair, resulting in repair failure. The purpose of this study was to compare the tension distribution along the repaired rotator cuff tendon among three double-row repair techniques.

Methods: In each of 42 fresh-frozen porcine shoulders, a simulated infraspinatus tendon tear was repaired by using 1 of 3 double-row techniques: (1) conventional double-row repair (no bridging suture); (2) transosseous-equivalent repair (bridging suture alone); and (3) compression double-row repair (which combined conventional double-row and bridging sutures).

Relationship Between Humeral Retroversion and Length of Baseball Career Before the Age of 16 Years.

Background: Humeral retroversion physiologically decreases during growth. However, in throwing athletes, the external forces caused by repetitive throwing are thought to increase humeral retroversion on the dominant side compared with that on the nondominant side.

Purpose: To investigate the correlation between humeral retroversion and length of baseball career before age 16 years.

Biomechanical Effects of Acromioplasty on Superior Capsule Reconstruction for Irreparable Supraspinatus Tendon Tears.

Background: Acromioplasty is increasingly being performed for both reparable and irreparable rotator cuff tears. However, acromioplasty may destroy the coracoacromial arch, including the coracoacromial ligament, consequently causing a deterioration in superior stability even after superior capsule reconstruction.

Purpose/hypothesis: The purpose of this study was to investigate the effects of acromioplasty on shoulder biomechanics after superior capsule reconstruction for irreparable supraspinatus tendon tears.

Three-dimensional ultrasound imaging of the pressure ulcer. A case report.

We report the case of a 46-year-old female who presented with a category IV pressure ulcer (PU) in the sacral region. Undermining of the PU was assessed with the aid of two-dimensional and three-dimensional ultrasound (3D-US).3D-US clearly visualized the wound in three directions and allowed determination of its volume.

Factors predicting perioperative delirium and acute exacerbation of behavioral and psychological symptoms of dementia based on admission data in elderly patients with proximal femoral fracture: A retrospective study.

Aim: To examine factors predicting the onset of perioperative delirium and acute exacerbation of behavioral and psychological symptoms of dementia (BPSD), based on patient background, operative background and laboratory data obtained on admission, in elderly patients with proximal femoral fracture.

Methods: The participants were 152 patients (aged >70 years) who underwent surgery between 1 November 2012 and 31 March 2014. The participants were classified into group B (with onset of perioperative delirium or acute exacerbation of BPSD, n = 52), or group N, (without onset, n = 100), and risk factors were retrospectively examined.

Effect of Anterior Capsular Laxity on Horizontal Abduction and Forceful Internal Impingement in a Cadaveric Model of the Throwing Shoulder.

Background: Excessive anterior capsular laxity (elongation of the anterior capsular ligaments) causes shoulder subluxation during acceleration of the throwing motion, leading to a disabled throwing shoulder. Few biomechanical studies have investigated the relationship between anterior capsular laxity and internal impingement, another cause of the disabled throwing shoulder.

Purpose/hypothesis: The purpose of this study was to assess the effect of anterior capsular laxity on forceful internal impingement during the late cocking phase.

Videofluoroscopy-guided balloon dilatation for treatment of severe pharyngeal dysphagia.

Balloon dilatation is a widely accepted technique in the management of esophageal and other types of gastrointestinal strictures, but it is rarely used for the treatment of pharyngeal dysphagia. Therefore, the aim of our prospective study was to evaluate the use of videofluoroscopy-guided balloon dilatation (VGBD) for the treatment of severe pharyngeal dysphagia. The study included 32 stroke patients who had been diagnosed with oral and/or pharyngeal dysphagia.

Biomechanical analysis of articular-sided partial-thickness rotator cuff tear and repair.

Background: Articular-sided partial-thickness rotator cuff tears are common injuries in throwing athletes. The superior shoulder capsule beneath the supraspinatus and infraspinatus tendons works as a stabilizer of the glenohumeral joint.

Purpose: To assess the effect of articular-sided partial-thickness rotator cuff tear and repair on shoulder biomechanics.

Isolated glenohumeral range of motion, excluding side-to-side difference in humeral retroversion, in asymptomatic high-school baseball players.

Purpose: Glenohumeral range of motion is correlated with shoulder capsular condition and is thus considered to be predictive of shoulder pathology. However, in throwing athletes, a side-to-side difference in humeral retroversion makes it difficult to evaluate capsular condition on the basis of glenohumeral range of motion measured by using the conventional technique. The purpose of this study was to measure isolated glenohumeral rotation, excluding side-to-side differences in humeral retroversion, in asymptomatic high-school baseball players.

Prompt analgesic effect of antihistaminic diphenhydramine ointment on bone-joint-muscle pain as assessed by skin impedance.

Pain is sensed, transmitted, and modified via a variety of mediators and their receptors. Histamine is a well-known mediator of pain. In addition to their antagonistic effects against histamine, classical antihistaminics possess, to various degrees, antimuscarinergic, antiserotonergic, antiadrenergic, local anesthetic, membrane-stabilizing and other pharmacologic actions.
