·AIM:To identify various risk factors that may play a significant role in the development of congenital nasolacrimal duct obstruction(CNLDO).·METHODS:This observational case-control study included a case group of 122 children less than two years of age with CNLDO who underwent probing and irrigation treatment at the ophthalmology department of Imam Khomeini Hospital in Ahvaz,Iran,from June 2022 to June2024.A control group of 122 age-matched children without CNLDO was also included for *** was collected from the children's medical records.·RESULTS:The study found a significant correlation between the occurrence of CNLDO and several maternal factors,such as preeclampsia,the use of levothyroxine,hypothyroidism,having more than three pregnancies(gravidity>3),natural pregnancy,and gestational diabetes ***,in children,factors,such as oxygen therapy,anemia,reflux,jaundice,and a family history of CNLDO in first-degree relatives were associated with CNLDO,and maternal preeclampsia and hypothyroidism were found to significantly increase the risk of developing CNLDO in children.·CONCLUSION:Given that CNLDO affects both premature and full-term children,the present findings may potentially facilitate the early identification of children and infants at risk of nasolacrimal duct obstruction,thereby preventing the onset of chronic dacryocystitis.

Background and Aims:The perinatal transmission of hepatitis B virus(HBV)remains an important global health ***,a systematic review and meta-analysis were conducted to evaluate the evidence regarding the efficacy and maternal/fetal safety of treating pregnant women with lamivudine,telbivudine(LdT),and tenofovir(TDF).Methods:A PubMed and Scopus search resulted in 1,076 records,which were reduced to 36,containing 7,717 pregnant women with chronic HBV infection and 7467 infants meeting the inclusion *** latest search was in August ***:Treatment with LdT,but not lamivudine and TDF,could significantly reduce the hepatitis B virus surface antigen-positive rate(odds ratio(OR)=0.37)in infants;it also led to higher rates of hepatitis B e antigen loss(OR=12.14),hepatitis B e antigen seroconversion(OR=8.93),and alanine aminotransferase normalization in mothers(OR=1.49).Each of these treatments was able to significantly reduce HBV DNA positivity at birth(total OR=0.19)and mother-to-child-transmission of HBV(total OR=0.15),and to cause higher rates of HBV DNA suppression in mothers(total OR=25.53).However,nucleos(t)ide analogues might also be involved in creatine kinase elevation(total OR=7.48).In contrast,no significant association was found between nucleos(t)ide analogue therapy and preterm/premature births,congenital malformation,low birth weight,and abortion or fetal/infant *** results suggested LdT's high capability of preventing ***,TDF failed to show significant associations to a reduced risk of mother-to-child-transmission,probably due to the low number of patients ***:Although using either lamivudine,LdT,orTDF could lead to more favorable maternal/fetal outcomes,LdT seemed to show more potential in resolving certain infant-and maternal-related *** studies on the safety profile of such treatments are required.
