Purple nonsulfur bacteria (PNSB) reportedly have probiotic effects in fish, but whether they are indigenous in the digestive tract of fish is a question that requires answering. We attempted to isolate PNSB from the digestive tract of ayu (Plecoglossus altivelis) from the Kuma River (Kumamoto, Japan) and successfully isolated 12 PNSB strains. All the isolated PNSB belonged to the genus Rhodopseudomonas. Five Rhodopseudomonas strains were also isolated from the soil samples collected along the Kuma River. The phylogenetic tree based on the partial sequence of pufLM gene indicated that the PNSB from ayu and soil were similar. The effects of NaCl concentration in growth medium on growth were also compared between the PNSB from ayu and soil. The PNSB from ayu showed a better growth performance at a higher NaCl concentration, suggesting that the intestinal tract of ayu, a euryhaline fish, might provide suitable environment for halophilic microorganisms.

Crohn's disease (CD) is a chronic, complex inflammatory disorder of the gastrointestinal tract that presents significant therapeutic challenges. Despite the availability of a wide range of treatments, many patients experience primary non-response, secondary loss of response, or adverse events, limiting the overall effectiveness of current therapies. Clinical trials often report response rates below 60%, partly due to stringent inclusion criteria.

Background: Intrathoracic kidney (ITK) is a rare congenital disease, with only about 40 pediatric cases reported worldwide to date. ITK associated with congenital diaphragmatic hernia (CDH) is even rarer, and we report a case of an infant with ITK combined with a giant CDH.
Case Description And Management: A six-month-old male infant was hospitalized due to "vomiting for 4 days".

The global incidence of allergic diseases is rising and poses a substantial threat to human health. Allergenic proteins released by various allergenic species play a critical role in the pathogenesis of allergic diseases and have been widely detected in the environmental matrix. However, the release, presence and interaction of environmental allergens with human body remain to be elucidated.

Pediatric patients with PRS are prone to upper airway obstruction during general anesthesia induction and intubation difficulties due to micrognathia and glossoptosis. In this case, we facilitated mask ventilation by inserting a nasopharyngeal airway before induction and successfully intubated the patient using a 2-person technique that combined the use of a video laryngoscope and a flexible fiber-optic scope.

Background: Preoperative fasting aims to reduce the risk of pulmonary aspiration. Our aim was to compare the incidence of increased gastric content after preoperative liberal versus a standard fasting in children.
Method: Two hundred children, presented for elective surgeries, were instructed to follow either 6-4-2 (standard group) or 6-4-0 (liberal group) preoperative fasting regimens.
