The use of nucleos(t)ide analogs (NAs) is recommended for mothers with a high viral load of hepatitis B virus (HBV) during the second or third trimester of pregnancy. However, postpartum hepatitis flares can occur in some cases. We examined the efficacy of NA administration for the prevention of mother-to-child transmission of hepatitis B virus, and evaluated the risk of postpartum hepatitis flares in mothers after NA discontinuation. Nine pregnant women with a high viral load (HBV DNA ≥5.3 log IU/mL) received tenofovir disoproxil fumarate (TDF) at approximately 28 weeks of gestation, and TDF was discontinued at 4-10 weeks after delivery...

Cerebral venous sinus thrombosis (CVST) is a rare cause of strokes and is most common in younger patients particularly those less than 50 years of age. It is more common in females than in males and is known to be associated with pregnancy, puerperium, oral contraception, congenital and acquired thrombophilia, and malignancy. Less commonly, it has been shown to be associated with infections and more recently has been found to be associated with COVID-19 infection with thrombocytopenia and the COVID-19 vaccine AstraZeneca...

UNLABELLED: Ebstein's anomaly (EA), a congenital cardiac anomaly, is characterized by apical displacement of the tricuspid valve leaflet(s) into the right ventricle. We present the case of a 61-year-old female with a history of EA, Wolff-Parkinson-White syndrome, and patent foramen ovale (PFO), who presented with worsening hypoxia and confusion, in the setting of left lower extremity cellulitis and abscess. The computed tomography (CT) scan of the head showed a cerebellar infarct with hemorrhagic conversion...

OBJECTIVE: To evaluate the serological diagnosis value of recombinant protein antigen Tp0608 for syphilis. METHOD: 406 patients with various stages of syphilis were enrolled. A recombinant protein antigen Tp0608 was established and ELISA was used to detect patients with various stages of syphilis. The results were compared with the conventional rapid plasma reagin test (RPR) and Treponema pallidum particle agglutination test (TPPA). The sensitivity of Tp0608 recombinant protein and RPR+TPPA screening was 96...

INTRODUCTION AND CLINICAL IMPORTANCE: Urethral duplication is a congenital anomaly characterized by the partial or full development of an auxiliary urethra as a second urethral channel varying in extent and location. The course of treatment for urethral duplication should be individualized for each patient based on the type of anomaly and the existence of symptoms. In most cases, if the ventral orthotopic urethra is normal, excision of the dorsal auxiliary urethra is almost always curative...

AIM: To determine (i) prevalence and the risk factors for acute kidney injury (AKI) in children hospitalised for febrile urinary tract infection (fUTI) and (ii) role of AKI as indicator of an underlying VUR. AKI, in fact, is favoured by a reduced nephron mass, often associated to VUR. METHODS: This retrospective Italian multicentre study enrolled children aged 18 years or younger (median age = 0.5 years) discharged with a primary diagnosis of fUTI...

BACKGROUND: Mother-to-child transmission is the primary cause of HIV cases among children. Antiretroviral therapy (ART) plays a critical role in preventing mother-to-child transmission and reducing HIV progression, morbidity, and mortality among mothers. However, after more than two decades of ART during pregnancy, the comparative effectiveness and safety of ART medications during pregnancy are unclear, and existing evidence is contradictory. This study aimed to assess the effectiveness and safety of different ART regimens among pregnant women living with HIV at preconception or during pregnancy...

AIM: Palivizumab has proven effective in reducing hospitalizations, preventing severe illness, improving health outcomes, and reducing healthcare costs for infants at risk of respiratory syncytial virus (RSV) infection. We aim to assess the value of palivizumab in preventing RSV infection in high-risk infants in Colombia, where RSV poses a significant threat, causing severe respiratory illness and hospitalizations. METHODS: We conducted a decision tree analysis to compare five doses of palivizumab with no palivizumab...

BACKGROUND: Vietnam continues to have measles and rubella outbreaks following supplementary immunization activities (SIA) and routine immunization despite both having high reported coverage. To evaluate immunization activities, age-specific immunity against measles and rubella, and the number of averted Congenital Rubella Syndrome (CRS) cases, must be estimated. METHODS: Dried blood spots were collected from 2,091 randomly selected individuals aged 1-39 years. Measles and rubella virus-specific immunoglobulin G (IgG) were measured by enzyme immunoassay...

BACKGROUND: Congenital CMV infection is the most common congenital infection worldwide and a major cause of neurological impairment and sensorineural hearing loss. Fetal CMV infection is confirmed by a positive PCR test in the amniotic fluid (amniocentesis performed after 18-20 weeks of gestation and at least 8 weeks after maternal infection). However, despite a negative antenatal CMV PCR result, some newborns can be tested positive at birth. Although not widely documented, the prognosis for these babies appears to be good...

Cerebral palsy (CP) is the most common disabling disease in children, and motor dysfunction is the core symptom of CP. Although relevant risk factors have been found to be closely associated with CP: congenital malformations, multiple gestation, prematurity, intrauterine inflammation and infection, birth asphyxia, thrombophilia, and perinatal stroke. Its important pathophysiological mechanism is amniotic fluid infection and intraamniotic inflammation leading to fetal developing brain damage, which may last for many years...

 Cyanosis is a bluish discoloration of the tissues due to increased levels of deoxygenated hemoglobin in capillaries. It is a common finding in newborn infants that can be caused by different diseases, including pulmonary, cardiac, infectious, and hematological disorders. Methemoglobinemia is a rare cause of cyanosis, in which hemoglobin is oxidized, changing its heme iron configuration from the ferrous (Fe2 +) to the ferric (Fe3 +) state, creating methemoglobin (Met-Hb), a form that does not bind oxygen, leading to decreased oxygen delivery to the tissues and cyanosis...

BACKGROUND: Congenital syphilis is a vertical infection caused by Treponema pallidum. Despite the implementation of preventive strategies during pregnancy, its incidence is increasing, and it constitutes an important public health problem. Most patients with congenital syphilis are asymptomatic; however, a small group may develop severe disease at birth with the need of advanced resuscitation in the delivery room, acute hypoxemic respiratory failure, and hemodynamic instability. Therefore, awareness is needed...

BACKGROUND: The use of selective serotonin reuptake inhibitors (SSRIs) has increased over time. Several studies indicate that paternal use of medication may adversely affect the developing fetus. Only a few studies have investigated the association between preconceptional paternal exposure to SSRIs and the risks of adverse health outcomes in children. OBJECTIVES: This study aimed to assess adverse birth outcomes and adverse early life events in children fathered by men using SSRIs prior to conception...

Congenital deformities of the spine lead to an imbalance in the longitudinal growth of the spine. These growth abnormalities may lead to three main patterns of deformity: scoliosis (the most common), kyphosis or lordosis (the least common). Despite the recent improvements in imaging and the routine use of neuromonitoring in the surgical treatment of congenital kyphosis, this surgery may be associated with a high rate of complications such as neurologic deficit, pulmonary thromboembolic events, infection, deep vein thrombosis, implant failure, and dural injury...

BACKGROUND: Plastic bronchitis (PB) can occur in patients who have undergone congenital heart surgery (CHS). This study aimed to investigate the clinical features of PB in children after CHS. METHODS: We conducted a retrospective cohort study using the electronic medical record system. The study population consisted of children diagnosed with PB after bronchoscopy in the cardiac intensive care unit after CHS from May 2016 to October 2021. RESULTS: A total of 68 children after CHS were finally included in the study (32 in the airway abnormalities group and 36 in the right ventricular dysfunction group)...

INTRODUCTION: There is substantial evidence that people with mental illness have higher mortality rates than the general population. However, most of the studies were from Western countries, and it is not clear whether this finding also applies to Arab countries like Qatar. OBJECTIVES: We aimed to explore whether mortality in patients with mental illness in Qatar, is different from those without. METHODS: We conducted a retrospective cohort study, including all Qatari nationals deceased in 2017 and 2018, using the list of registered deaths from Hamad Medical Corporation (HMC) Mortuary...

BACKGROUND: Congenital cytomegalovirus (cCMV) is the most common congenital viral infection in the United States. Symptomatic infections can cause severe hearing loss and neurological disability, although ~ 90% of cCMV infections are asymptomatic at birth. Despite its prevalence, the long-term neurobehavioral risks of asymptomatic cCMV infections are not fully understood. The objective of this work was to evaluate for potential long-term neurobehavioral sequelae in infants with asymptomatic cCMV...

BACKGROUND: Various factors contribute to the development of infection-related acute encephalopathy (AE) in children, such as infectious agents and chronic underlying disorders. We studied underlying disorders in children with AE to identify predisposing factors of AE. METHODS: We investigated underlying disorders or past histories in patients with two types of AE from the database in the Tokai area of Japan between 2009 and 2022: 204 patients with AE with reduced subcortical diffusion (AED) and 137 with clinically mild encephalopathy with a reversible splenial lesion (MERS)...

Zika virus (ZIKV), an arbovirus from the Flaviviridae family, is the causative agent of Zika fever, a mild and frequent oligosymptomatic disease in humans. Nonetheless, on rare occasions, ZIKV infection can be associated with Guillain-Barré Syndrome (GBS), and severe congenital complications, such as microcephaly. The oligosymptomatic disease, however, presents symptoms that are quite similar to those observed in infections caused by other frequent co-circulating arboviruses, including dengue virus (DENV)...
