Background: Geographic tongue is an oral mucosal lesion affecting the tongue. The association between geographic tongue and the mucosal microbiota in children remains unclear.

Method: To characterize the feature of lingual microbiota in pediatric geographic tongue, lingual swabs were collected from lesion sites and healthy sites of 25 patients with geographic tongue (14 males and 11 females; age 5.21 ±2.94 years) and 19 controls (10 males and 9 females; age 5.31±2.82 years). DNA was extracted and the 16S rRNA was amplificated, sequenced and analyzed.

Results: The lingual microbiota composition was significantly different between children with geographic tongue and the healthy cohort; Streptobacillus was reduced in geographic tongue, while Catonella, Bacillus and Oribacterium were overrepresented. When the lesions and the normal mucosa were compared, an increased abundance of Prevotella oris was observed.

Conclusion: Our results provided new insight into the association between oral microbiota and pediatric geographic tongue.

Background: Viral myocarditis (VMC) is common in children. Previous studies have reported the clinical value of nuclear paraspeckle assembly transcript 1 (NEAT1) and microRNA-425-3p (miR-425-3p) in certain diseases, but not in VMC. This article was designed to investigate the expression of long noncoding RNA (lncRNA) NEAT1 and miR-425-3p in the serum of patients with VMC and their clinical significance.

Methods: We assessed VMC and healthy patients and analyzed differences in the expression levels of NEAT1 and miR-425-3p. The correlation and targeting relationship between the two were reported by Spearman correlation analysis and luciferase reporter assay. ROC curves were plotted to reflect the diagnostic effect of both. In addition, according to the 12-month prognostic effect grouping, patients with VMC were separated into a group with good vs. poor prognosis, and the difference in the expression levels of NEAT1 and miR-425-3p between the two groups were analyzed. The ability of the two markers in the prognosis of VMC was further analyzed by multiple logistic regression.

Results: NEAT1 expression was up-regulated in VMC and miR-425-3p expression was down-regulated, and there was a negative correlation and targeting link between the two. The diagnostic efficacy of both NEAT1 and miR-425-3p was higher than that of a single indicator. High expression of NEAT1 and low expression of miR-425-3p were found in VMC patients with poor prognosis. Both were independent influencers of VMC prognosis.

Conclusion: NEAT1 and miR-425-3p expressions were affected by VMC and had important clinical implications for VMC, indicating for the first time the clinical function of NEAT1 and miR-425-3p in VMC.

Background: Hyperkalemia is one of the most serious electrolyte disturbances, and it can cause lethal cardiac arrhythmia. Although hyperkalemia associated with ileostomies has been reported in adults, to the best of our knowledge, it has not previously been reported in neonates.

Case: We report ileostomy‒induced hyperkalemia that persisted during the ileostomy and resolved promptly after the closure of the ileostomy in two extremely low birth weight (ELBW) infants, with birth weights of 850 g and 840 g and gestational ages of 27 weeks and 27 weeks 6 days.

Conclusions: These cases highlight that disruption of intestinal integrity in ELBW infants may cause hyperkalemia. Ensuring the integrity of the gastrointestinal tract plays an important role in the treatment of electrolyte disorders such as hyperkalemia in ELBW infants with an ileostomy.

Background: There is a need to identify the complex interplay between various physiological mechanisms in primary ciliary dyskinesia (PCD) and cystic fibrosis (CF). The study investigated the interaction between respiratory function, exercise capacity, muscle strength, and inflammatory and oxidant/antioxidant responses in patients with PCD and CF.

Methods: The study included 30 PCD patients, 30 CF patients, and 29 age and sex-matched healthy subjects. Exercise capacity was assessed using the modified shuttle walk test (MSWT). Handgrip strength (HGS) was used to evaluate general muscle strength. Oxidative stress-inflammatory parameters were also assessed. Pulmonary function test was performed by spirometry. Regarding the forced expiratory volume in 1 second (FEV1) z-score, patients with PCD and CF were subdivided into normal, mild, and severe/moderate groups.

Results: Forced vital capacity (FVC) z-scores were lower in PCD and CF patients than controls. FEV1, FEV1/FVC, peak expiratory flow (PEF), and forced mid expiratory flow (FEF25-75%) z-scores were lower in PCD than in the other groups. HGS was lower in both mild PCD and normal CF patients relative to the controls. MSWT distance was lower in severe/moderate PCD patients than controls. Catalase (CAT), glutathione S-transferase (GST), glutathione peroxidase (GPx), and malondialdehyde (MDA) levels did not differ significantly among the study groups, but superoxide dismutase (SOD) level in severe/moderate PCD, and glutathione (GSH) level in normal CF were higher than in controls. Interleukin-6 (IL-6) level was higher in patients with normal PCD and CF compared to the controls. IL-1β level was higher in PCD compared to controls. Additionally, correlations among these parameters were also determined in some patient groups.

Conclusion: Homeostasis related to respiratory function, aerobic performance, muscle strength, inflammatory response, and oxidant/antioxidant balance were affected in PCD and CF. Evaluating these mechanisms together may contribute to elucidating the pathophysiology of these rare diseases.
