Abstract
We aimed to determine the clinical impact of conjunctivochalasis (CCh) and its correction using high-frequency radiowave electrosurgery (HFR-ES), for signs and symptoms of dry eye disease (DED). Forty patients diagnosed with symptomatic CCh were prospectively enrolled. As a result, patients with CCh had moderate to severe DED and most of them exhibited meibomian gland dysfunction (MGD). Corneo-conjunctival fluorescein staining score (CFS) and all lid-parallel-conjunctival-folds scores (LIPCOFs) were positively correlated. Nasal LIPCOF significantly correlated with symptoms and tear volume. Central, temporal, and total LIPCOF significantly correlated with MG loss, MGD stage, and lipid layer thickness. Independent significant factors associated with total LIPCOF included CFS, tear break-up time, and MGD stage. One month following HFR-ES, CCh was completely resolved in all cases. Patient age and preoperative nasal LIPCOF were determinants of outcomes associated with postoperative improvements in symptoms. Ocular surface parameters significantly improved, but MGD-related signs did not. Collectively, CCh associated with MGD severity deteriorates not only tear film stability and reservoir capacity, leading to DED exacerbation. Therefore, CCh should be corrected in patients with DED and MGD. Younger patients with nasal CCh are likely to experience more symptomatic relief after HFR-ES. Particularly, management for MGD should be maintained after CCh correction.

Co-circulation of coxsackieviruses A-6, A-10, and A-16 causes hand, foot, and mouth disease in Guangzhou city, China. BMC Infect Dis 2020; 20:271. [PMID: 32264839 PMCID: PMC7137261 DOI: 10.1186/s12879-020-04992-x] [Citation(s) in RCA: 20] [Impact Index Per Article: 5.0] [Reference Citation Analysis] [What about the content of this article?

Abstract
Background Hand, foot, and mouth disease (HFMD) is a common infectious disease occurring in children under 5 years of age worldwide, and Enterovirus A71 (EV-A71) and Coxsackievirus A16 (CVA-16) are identified as the predominant pathogens. In recent years, Coxsackievirus A6 (CVA-6) and Coxsackievirus A10 (CVA-10) have played more and more important role in a series of HFMD outbreaks. This study aimed to understand the epidemic characteristics associated with HFMD outbreak in Guangzhou, 2018. Methods The clinical and laboratory data of 1220 enterovirus-associated HFMD patients in 2018 were analysed in this study. Molecular diagnostic methods were performed to identify its serotypes. Phylogenetic analyses were depicted based on the complete VP1 gene. Results There were 21 enterovirus serotypes detected in Guangzhou in 2018. Three serotypes of enterovirus, CVA-6 (364/1220, 29.8%), CVA-10 (305/1220, 25.0%), and CVA-16 (397/1220, 32.5%), were identified as the causative pathogens and accounted for 87.3% among all 1220 HFMD patients. In different seasons, CVA-6 was the predominant pathogen of HFMD during autumn, and CVA-10 as well as CVA-16 were more prevalent in summer. Patients infected by CVA-6, CVA-10 or CVA-16 showed similar clinical features and laboratory characteristics, and the ratios of severe HFMD were 5.8, 5.9, and 1.5% in the three serotypes. Phylogenetic analyses of VP1 sequences showed that the CVA-6, CVA-10, and CVA-16 sequences belonged to the sub-genogroup E2, genogroup E, and genogroup B1, respectively. Conclusions CVA-6, CVA-10, and CVA-16 were the predominant and co-circulated serotypes in Guangzhou China, 2018, which should be the new target for prevention and control of HFMD. Our findings provide useful information for diagnosis, treatment, and prevention of HFMD.
