ABSTRACT

Microbiota composition may play a role in the development, prognosis, or post-infection of COVID-19. There are studies evaluating the microbiota composition at the time of diagnosis and during the course of COVID-19, especially in adults, while studies in children are limited and no study available in children with multisystem inflammatory syndrome in children (MIS-C). This study was planned to compare intestinal microbiota composition in children diagnosed with MIS-C and acute COVID-19 infection with healthy children. In this prospective multicenter study, 25 children diagnosed with MIS-C, 20 with COVID-19 infection, and 19 healthy children were included. Intestinal microbiota composition was evaluated by 16 s rRNA gene sequencing. We observed changes of diversity, richness, and composition of intestinal microbiota in MIS-C cases compared to COVID-19 cases and in the healthy controls. The Shannon index was higher in the MIS-C group than the healthy controls (p < 0.01). At phylum level, in the MIS-C group, a significantly higher relative abundance of Bacteroidetes and lower abundance of Firmicutes was found compared to the control group. Intestinal microbiota composition changed in MIS-C cases compared to COVID-19 and healthy controls, and Faecalibacterium prausnitzii decreased; Bacteroides uniformis, Bacteroides plebeius, Clostridium ramosum, Eubacterium dolichum, Eggerthella lenta, Bacillus thermoamylovorans, Prevotella tannerae, and Bacteroides coprophilus were dominant in children with MIS-C. At species level, we observed decreased Faecalibacterium prausnitzii, and increased Eubacterium dolichum, Eggerthella lenta, and Bacillus thermoamylovorans in children with MIS-C and increased Bifidobacterium adolescentis and Dorea formicigenerasus in the COVID-19 group. Our study is the first to evaluate the microbiota composition in MIS-C cases. There is a substantial change in the composition of the gut microbiota: (1) reduction of F. prausnitzii in children with MIS-C and COVID-19; (2) an increase of Eggerthella lenta which is related with autoimmunity; and (3) the predominance of E. dolichum is associated with metabolic dysfunctions and obesity in children with MIS-C. CONCLUSIONS:  Alterations of the intestinal microbiota might be part of pathogenesis of predisposing factor for MIS-C. It would be beneficial to conduct more extensive studies on the cause-effect relationship of these changes in microbiota composition and their effects on long-term prognosis. WHAT IS KNOWN: • Microbiota composition may play a role in the development, prognosis, or post-infection of COVID-19.  • However, the number of studies on children is limited, and no study on multisystem inflammatory syndrome in children is currently available (MIS-C). WHAT IS NEW: • In individuals with MIS-C, the composition of the gut microbiota changed dramatically. • Decreased Faecalibacterium prausnitzii have been observed, increased Eggerthella lenta, which was previously linked to autoimmunity, and predominance of Eubacterium dolichum which was linked to metabolic dysfunction and obesity.

ABSTRACT

BACKGROUND AND OBJECTIVE: the global prevalence of allergic rhinitis (AR) is rising and yet there is scarce information concerning the diagnosis, management and treatment patterns of AR in Northern Cyprus (NC). This study aims to provide a unique perspective on AR management as well as assessing the effectiveness of the pharmacist-led educational intervention for improving care of AR patients. METHODS: across-sectional survey was carried out with community pharmacists (n = 70), patients (n = 138) and ear, nose and throat (ENT) specialists (n = 12) in NC. For a controlled interventional trial, trained pharmacists provided a brief education on management of AR and nasal spray technique for patients while other pharmacists provided the usual care. Quality of life (QoL) and other outcome measures on the perceived symptom severity of the two groups were compared after a 6-week period. RESULTS: only 33.3% of the ear, nose and throat (ENT) specialists and 15.7% of the community pharmacists are aware of the Allergic Rhinitis and its Impact on Asthma (ARIA) guidelines. The majority of patients (63%) self-managed with over-the-counter medications. Nasal congestion (96.4%) is the most bothersome symptom and oral antihistamines are the most commonly purchased medications (51.4%), indicating a pattern of suboptimal management. The pharmacists-led educational intervention has resulted in statistically more significant improvement in regards to nasal congestion and QoL for the intervention group patients (p < 0.05). CONCLUSION: the current management of AR has not been in accordance with the ARIA guidelines in NC. An educational intervention of the pharmacists can enhance the symptom management and improve the QoL in patients with AR.

ABSTRACT

Collision tumors in the paranasal region are extremely rare with limited literature data. To the best of our knowledge, this is the first report of associations of squamous cell carcinoma-esthesioneuroblastoma and lymphoma-hemangiopericytoma in the paranasal region. Preoperatively, radiological and clinical findings should be evaluated carefully for the diagnosis and two or more biopsy specimens should be taken from different morphological parts of the lesions. Adjuvant therapy should be planned according to two different histologies and special importance should be given to the tumor which indicates the prognosis of the patient. A multidisciplinary approach is required for the management of synchronous malignancies.

ABSTRACT

OBJECTIVES: To identify the effects of laryngopharyngeal reflux (LPR)-related laryngeal findings on objective voice parameters. METHODS: Two hundred and thirty patients clinically diagnosed as having LPR and 48 healthy controls were included. The reflux finding score was determined for each subject via videolaryngoscopy. The acoustic parameters evaluated were jitter, shimmer, noise-to-harmonic ratio and Voice Turbulence Index (VTI). RESULTS: Shimmer and VTI showed statistically significant differences between the LPR and control groups among males (p < 0.05). For females, all of the 4 acoustic voice parameters were significantly different between the two groups (p < 0.05). Erythema/hyperemia was found to affect the highest number of voice parameters. VTI was found to be affected by the highest number of laryngeal findings. CONCLUSION: Objective voice changes were documented in LPR patients, with VTI being the most affected parameter, and therefore it should be considered in the acoustic analysis of patients with LPR in addition to the conventional parameters. With hyperemia in the first rank, ventricular obliteration, pseudosulcus and vocal fold edema are found to have an impact on voice, suggesting that these should be concentrated on in the diagnosis and follow-up of LPR patients with voice disorders.

ABSTRACT

The techniques used in the diagnosis of gastroesophageal reflux disease (GERD) have insufficient specificity and sensitivity in diagnosing laryngopharyngeal reflux (LPR). The purpose of this study was to evaluate the role of esophagogastroduodenoscopy (EGD) and laryngological examination in the diagnosis of LPR. A total of 684 diagnosed GERD and suspected LPR patients were prospectively scored by the reflux finding score (RFS) which was suggested by Koufman. A total of 484 patients with GERD who had RFS ≥ 7 were accepted as having LPR. 248 patients with GERD plus LPR on whom an endoscopic examination was performed were evaluated. As a control group, results from 82 patients with GERD who had RFS <7 were available for comparison. The GERD symptom score (RSS) was counted according to the existence of symptoms (heartburn/regurgitation) and frequency, duration, and severity. The reflux symptom index (RSI) suggested by Belafsky et al. was also evaluated. The relationship between esophageal endoscopic findings, RSS, RFS and RSI was investigated. Mean age was 46 ± 12 (19-80). The mean values of RSS, RFS, and RSI were 18.9 ± 7.7, 10 ± 2.2, 16.6 ± 11.9, respectively. Erosive esophagitis was detected in 75 cases (30%). Hiatus hernia was observed in 32 patients (13%). There was no correlation between RSS and RFS, RSI. The severity of esophagitis did not correlate with the severity of the laryngeal findings. LPR should be suspected when the history and laryngoscopy findings are suggestive of the diagnosis. EGD has no role in the diagnosis of LPR.
