Treatment outcomes and time to healing of medication-related osteonecrosis of the jaw based on image findings.

Objectives: This study aimed to evaluate the prognostic treatment outcome of non-operative management of medication-related osteonecrosis of the jaw (MRONJ), particularly regarding the relationship between image findings and treatment outcomes.

Methods: This single-center, retrospective observational study included patients with MRONJ who were conservatively treated between 2010 and 2020. All patients were evaluated in terms of MRONJ treatment outcomes, time to healing, and prognostic factors, including sex, age, underlying disease, antiresorptive drug type, discontinuation of antiresorptive treatment, chemotherapy, corticosteroid treatment, diabetes mellitus, location of MRONJ, clinical stage of MRONJ, and computed tomography image findings.

Initial national investigation of the prenatal diagnosis of congenital heart malformations in Japan-Regional Detection Rate and Emergency Transfer from 2013 to 2017.

Background: Investigation into the detection rate (DR) of congenital heart diseases (CHDs) in fetuses is important for the assessment of fetal cardiac screening systems.

Objectives: We highlight issues of fetal cardiac screening in Japan.

Methods: We performed an initial national survey of fetal diagnosis of CHDs from the data of the national registry for congenital heart surgery from 2013 to 2017.

Influence of prostate cancer status on the prevalence of medication-related osteonecrosis of the jaw.

Objective: The aim of this study was to evaluate the risk of osteonecrosis of the jaw (ONJ) in patients with prostate cancer, particularly the relationship between prostate cancer progression and ONJ development.

Study Design: This single-center, retrospective, observational study included 113 patients who received zoledronic acid or denosumab for prostate cancer with bone metastasis between January 2012 and March 2020. The risk of ONJ was evaluated regarding age; antiresorptive drugs; duration of antiresorptive treatment; prostate cancer status, including castration-resistant prostate cancer (CRPC) and prostate-specific antigen level; chemotherapy; radium-223 treatment; corticosteroid treatment; diabetes mellitus; and dental extractions.

A burden of sarcomere gene variants in fetal-onset patients with left ventricular noncompaction.

Background: Left ventricular noncompaction (LVNC) is a hereditary cardiomyopathy, associated with high morbidity and mortality, but the role of genetics in cases of fetal-onset has not been fully evaluated. The goal of this study was to identify the genetic background in LVNC fetal-onset patients using next-generation sequencing (NGS).

Methods: Thirty-three fetal-onset Japanese probands with LVNC (20 males and 13 females) were enrolled.

Cardiofaciocutaneous syndrome with KRAS gene mutation presenting as chylopericardium.

A 12-year-old female patient with cardiofaciocutaneous syndrome in the presence of a KRAS gene mutation had episodes of pericardial effusion on ultrasound, later confirmed to be chylopericardium, which resolved after a lymphangiography. We discussed herein the pathophysiological background of this rare case and the efficacy of lymphangiography in the treatment of chylopericardium.

Right-sided hepatic hernia of normal left lobe resembling cardiac tumor.

A 3-year-old boy was referred for cardiac tumor diagnosed on transthoracic echocardiography (TTE) at another hospital. The tumor appeared to be in the right atrium and obstructed inferior vena cava flow. TTE, enhanced computed tomography (CT) and angiography were done to confirm diagnosis.
