“…A few articles have reported that P. oris can cause pleural effusion and pleuropulmonary infections. 24,26 In addition, animal studies have suggested that coinfection of mice with P. intermedia and S. constellatus results in more severe pneumonia and higher mortality than infection with each pathogen separately, and may lead to lung abscesses and empyema. 27 Therefore, we believe that P. oris may also play a role as a co-source of infection.…”

Empyema is a common complication of pneumonia, caused by the accumulation of purulent exudate due to pathogenic bacteria invading the pleural cavity. Parvimonas micra and Streptococcus constellatus are pathogens that rarely cause pneumonia with empyema. Herein, a case of severe empyema caused by these two pathogens, confirmed by metagenomic next-generation sequencing (mNGS) of pleural effusion cultures, is reported. A male Chinese patient in his late sixties presented with wheezing, cough, sputum expectoration, and fever. Blood and sputum cultures were negative for pathogens, but the pleural effusion culture was positive for S. constellatus, and was also found to contain P. micra, confirmed by mNGS. The patient’s symptoms improved after treatment with cefoperazone/sulbactam and moxifloxacin. Pneumonia caused by P. micra and S. constellatus is rare; however, coinfection with these pathogens may cause severe pneumonia, with or without empyema.

Letters to the Editor arthritis in the differential diagnosis, even in pediatric patients without any predisposing factors. The particularity of the case presented was the lack of gastrointestinal manifestations.Salmonella osteomyelitis, although rare, should be considered in the differential diagnosis of pediatric osteomyelitis, especially when atypical presentations are observed, even in immunocompetent children without risk factors. Timely diagnosis, appropriate antibiotic therapy and surgical intervention, when necessary, contribute to favorable outcomes.

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.
