Effect of exercise devised to reduce arm tremor in the sighting phase of archery.

Background: In archery training, side bridges are performed in a posture similar to archery shooting for training the muscles around the shoulder joint and the shoulder girdle of the pusher.

Aim: The purpose of this study was to determine whether a low-tremor side-bridge exercise for 4 weeks improves bow tremor during archery movements.

Methods: Participants were 20 male college students.

Development of serological assays to identify and . infections.

, hosted by hogs, is the most prevalent gastric non- species found in humans. Recent studies have suggested that infection has caused many cases of gastric disease, but the transmission route from hogs remains unclear. Diagnostic methods based on urease activity often yield negative results, and there is no reliable method for diagnosing infection in clinical practice without gastric biopsy specimens.

Slowly Progressive Bone Marrow Metastasis of Gastric Cancer Followed-up Without Treatment.

Background/aim: Bone marrow metastasis (BMM) of gastric cancer (GC) is complicated by disseminated intravascular coagulation syndrome (DIC), which is more prominent in poorly differentiated carcinoma. This is one of the first case reports of a slowly progressing BMM of GC after approximately 1 year of follow-up without treatment.

Case Report: A 72-year-old woman underwent total gastrectomy and splenectomy for GC in February 2012.

COVID-19 delirium and encephalopathy: Pathophysiology assumed in the first 3 years of the ongoing pandemic.

Background: The coronavirus disease (COVID-19) continues to spread worldwide. It has a high rate of delirium, even in young patients without comorbidities. Infected patients required isolation because of the high infectivity and virulence of COVID-19.

Risk factors for pathological fracture in patients with mandibular osteoradionecrosis.

Osteoradionecrosis (ORN) often results in pathological fractures through progression. We aimed to identify the risk factors for pathological fracture in patients with mandibular ORN. Seventy-four patients with mandibular ORN were included in this retrospective study.

A case of chronic eosinophilic pneumonia associated with rheumatoid arthritis in glucocorticoid-free remission with JAK inhibitor: A case report.

Rationale: Chronic eosinophilic pneumonia (CEP) presents eosinophil infiltrations in the lung due to allergic reactions. Most CEP patients continue to take glucocorticoids, and their prolonged use induces various side effects. In this case report, based on the efficacy of baricitinib in patients with rheumatoid arthritis (RA) and CEP, we aimed to show that the administration of Janus kinase (JAK) inhibitors, when RA is complicated by an allergic disease, can stabilize the disease state and help avoid the adverse effects of long-term systemic glucocorticoid administration.

Clinical features and associated factors of intraocular inflammation following intravitreal brolucizumab as switching therapy for neovascular age-related macular degeneration.

Purpose: The aim of this study is to explore the clinical features and associated factors of intraocular inflammation (IOI) following intravitreal brolucizumab (IVBr) administration for neovascular age-related macular degeneration (nAMD).

Methods: This retrospective study included 87 eyes from 87 Japanese patients with nAMD who were followed up for 5 months after the initial administration of IVBr as switching therapy. Clinical pictures of IOI post-IVBr and changes in best corrected visual acuity (BCVA) at 5 months were evaluated between eyes with and without IOI (non-IOI).

Relationship between oral health and prognosis in patients with empyema: Single center retrospective study with propensity score matching analysis.

Background: Empyema is a life-threatening infection often caused by oral microbiota. To the best of our knowledge, no reports have investigated the association between the objective assessment of oral health and prognosis in patients with empyema.

Materials And Methods: A total of 63 patients with empyema who required hospitalization at a single institution were included in this retrospective study.

The dynamics of laboratory markers reflecting cytokine overproduction in macrophage activation syndrome complicated with systemic juvenile idiopathic arthritis.

Objectives: To validate the correlation between laboratory markers reflecting disease activity of macrophage activation syndrome (MAS) and serum cytokine levels and identify the valuable laboratory markers that change over time for a prompt MAS diagnosis.

Methods: Serum cytokine levels were determined by enzyme-linked immunosorbent assay and compared with laboratory markers reflecting MAS disease activity.The changes in values were evaluated from the acute phase of systemic juvenile idiopathic arthritis (s-JIA) to MAS diagnosis.

Pacemaker implantation for persistent sinus node dysfunction in a patient with COVID-19.

A 46-year-old woman was admitted with coronavirus disease-2019 infection. Symptomatic sinus bradycardia occurred, followed by congestive heart failure. Therapeutics such as isoproterenol, theophylline, and cilostazol could not safely improve her symptoms.

Delayed diagnosis of bladder cancer in a patient with autosomal dominant polycystic kidney disease.

Approximately 50% of autosomal dominant polycystic kidney disease (ADPKD) patients have gross hematuria, but few cases of bladder cancer complications are known. We report a case of a 49-year-old female ADPKD patient with bladder cancer, who was presented to our hospital 4 months after the onset of gross hematuria. A computed tomography (CT) scan showed a bladder mass, enlarged pelvic and left inguinal lymph nodes, multiple liver cysts, and a polycystic kidney.

Case report: Paratesticular dedifferentiated liposarcoma with poor prognosis.

Background/aim: Most paratesticular liposarcomas (PLPSs) are well-differentiated liposarcomas (WDLPSs) with favourable prognoses. As such, the rare occurrence of PLPS often leads to its misdiagnosis as a hernia or hydrocele on physical examination. Curative resection of the tumour may not be possible in cases where PLPSs have transformed into dedifferentiated liposarcomas (DDLPSs) owing to a delay in diagnosis.

Hematologic and inflammatory parameters for determining severity of odontogenic infections at admission: a retrospective study.

Background: Severe odontogenic infections in the head and neck region, especially necrotizing soft tissue infection (NSTI) and deep neck abscess, are potentially fatal due to their delayed diagnosis and treatment. Clinically, it is often difficult to distinguish NSTI and deep neck abscess in its early stage from cellulitis, and the decision to perform contrast-enhanced computed tomography imaging for detection is often a challenge. This retrospective case-control study aimed to examine the utility of routine blood tests as an adjunctive diagnostic tool for NSTI in the head and neck region and deep neck abscesses.

Assessment of photodynamic therapy as a salvage treatment for local failure after chemoradiotherapy or radiotherapy for esophageal cancer in patients aged 80 years or older.

Objectives: Chemoradiotherapy (CRT) or radiotherapy (RT) alone is often the treatment of choice for elderly patients with esophageal cancer with the expectation of organ preservation. However, salvage treatment remains a problem when endoscopic resection is not indicated for local failure after CRT/RT. Photodynamic therapy (PDT) is indicated for local failure after CRT/RT, but there are few reports on its efficacy and safety in elderly patients.

Neonatal Pseudohypoaldosteronism Type-1 in Japan.

(1) Background: Pseudohypoaldosteronism type 1 (PHA-1) is a disorder caused by renal tubular resistance to aldosterone and is characterized by problems with sodium regulation. PHA-1 is typically divided into primary PHA-1, which is caused by genetic mutation, and secondary PHA-1, which is associated with urinary tract abnormality. However, data on the clinical features of PHA-1 among newborn infants are limited.

A good surgical field for para-aortic nodal dissection in gastric cancer by the Cattell-Braasch maneuver.

Purpose: Gastric cancer patients with para-aortic lymph node metastases may achieve long-term survival with radical gastrectomy and para-aortic lymph nodal dissection (PAND) following neoadjuvant therapy. We introduced the Cattell-Braasch maneuver to facilitate safe and complete PAND for advanced gastric cancer with extensive lymph node metastases.

Methods: Between January 2014 and March 2020, 7 patients with highly advanced gastric cancer received preoperative chemotherapy followed by radical gastrectomy and PAND using the Cattell-Braasch maneuver.
