A bulging fontanel is a sign of elevated intracranial pressure, which can be caused by diseases with intracranial fluid retention or swelling of the cerebral parenchyma. We experienced a case of an infant with a typical course of mild coronavirus disease 2019 (COVID-19) but with a bulging fontanel as a finding at presentation. The patient, a three-month-old boy with no underlying conditions, presented to the emergency clinic with fever, vomiting, and loss of appetite.

Introduction: Evidence regarding the factors affecting the geographical variation of antimicrobial use (AMU) is relatively scarce. This study aimed to evaluate factors potentially associated with geographical variability of AMU per day per 1000 habitants in the 47 prefectures of Japan.
Methods: This is an observational ecological study using the Japanese national database in 2019.
Voriconazole (VRCZ) is an antifungal drug that necessitates therapeutic monitoring (TDM). Typically, TDM is recommended for patients undergoing long-term outpatient treatment. However, in Japan, insurance reimbursement for TDM is only permitted for inpatients.

While a nudge-based ASP publishing monthly newsletters reduces inappropriate prescription of oral third-generation cephalosporins (3GCs), which requires considerable effort. Therefore, developing more preferable ASP models in PECs is essential.

The first edition was published in 2004 and the fifth edition was published in 2022. The Guideline 2022 consists of 2 parts, clinical questions and commentary, and includes general respiratory infections and specific infections in children with underlying diseases and severe infections.

Investigating the actual conditions in which macrolides are used is important for identifying further interventions for appropriate antimicrobial use; however, this situation has not been evaluated in Japan. Therefore, we aimed to clarify the number of macrolide prescriptions and their changes before and after implementation of the Antimicrobial Resistance (AMR) Action Plan.

We describe the case of a female infant who was initially diagnosed with BRUE but was later determined to have intussusception. She presented to our emergency department with a transient pallor and a single episode of vomiting that resolved before her visit.

Herein, we report two pediatric cases of FPIES to solid soy foods, such as tofu. The patients presented with repetitive vomiting after eating the trigger food as infant food.

However, relevant epidemiological data in Japan are scarce. Materials and methods This observational, single-center study investigated the epidemiology of fever in infants aged ≤90 days.

We initially suspected anorexia nervosa (AN). However, she did not express fear of gaining weight or have a distorted perception of her weight or body shape; thus, her presentation was not typical of AN.

DID is frequently used to monitor national AMU trends, this metric does not intrinsically take temporal changes in population age structure into account. We examined the effects of population age structure on DID estimates of parenteral AMU in Japan, and predicted future trends in DDDs based on population projections.

The questionnaire described three hypothetical scenarios (aspiration pneumonia, pyelonephritis, and neoplastic fever) in older patients with terminal cancer, and 25 respondents answered questions on testing and treatment strategies. Most respondents chose to obtain cultures for aspiration pneumonia (sputum) and for pyelonephritis (urine), although fewer respondents chose to obtain blood cultures.

Management of the efficacy and safety of VCM has been implemented with the assignment of pharmacists in hospital wards and the establishment of teams related to infectious diseases. However, there are no reports evaluating the association between these factors and the efficacy and safety of VCM in large populations.

Antimicrobial resistance (AMR) is a major problem in public health. Japan is addressing this problem with various measures based on the National Action Plan on AMR, published in 2016. In Japan, the fight against AMR is hindered by issues with the health care system, including the lack of a general practitioner registration system, an abundance of private clinics and health care for infants and toddlers being essentially free of charge.

Arbekacin (ABK) is used to treat pneumonia and sepsis caused by methicillin-resistant Staphylococcus aureus, and therapeutic drug monitoring (TDM) is recommended. This study aimed to clarify the trend in TDM implementation for ABK over time and the factors associated with TDM implementation using a claims database.

Using nationwide antimicrobial sales data, we examined the annual and monthly trends in AU from 2016-2020 according to the AWaRe classification (Access and Watch categories) and administration route (oral and injectable). To analyze the possible impact of the COVID-19 pandemic on AU, seasonal autoregressive integrated moving average (SARIMA) models were used to predict AU in 2020 (based on the trends from 2016-2019) under the assumption that the pandemic did not occur.

However, the details of the prescribing medical institutions and regional characteristics are unknown. Therefore, the purpose of this study was to clarify the details of the medical institutions where antibiotics for CDI were prescribed, and evaluate the AMU for CDI and the regional characteristics.
