Background: Oral thrush is a common yeast infection caused by Candida albicans in infants during their first few weeks or months. Infant mothers' antibiotics consumption can contribute to this opportunistic fungal growth due to their weaker immune systems. Objectives: To investigate the relationship between maternal antibiotic consumption and oral thrush infection in breastfeeding infants, this study aims to provide insights for health care professionals regarding antibiotic prescriptions and preventive strategies for managing oral thrush. Methods: A quasi-experimental design with a control group was used. Eighty-two breastfeeding infants were divided into two groups: Group 1 (n = 40) infants of antibiotic-consuming mothers and Group 2 (n = 42) infants of nonantibiotic-consuming mothers. The oral samples were collected using sterile cotton swabs and cultured on Sabouraud's dextrose agar C. albicans, confirmed by simple staining and a germ tube test. Results: Infants aged 1-11 months with a mean ± standard deviation of 4.8 ± 3.51. Within all 82 oral swabs, 42.7% were positive for C. albicans growth and 57.3% were negative. The highest percentage was in 1-month-old infants (n = 9, 25.71%), and the lowest was in 11 months old (n = 2, 5.71%). Group 2 infants had significantly fewer positive C. albicans growth (n = 12, 28.57%) compared with group 1 (n = 23; 57.5%) (χ2 = 7.0, p = 0.007; odds ratio = 3.332, 95% confidence interval = 1.35-8.46). Oral thrush clinical signs were identified in 66.6% and 33.4% of group 1 and 2 infants, respectively, while 31.4% of C. albicans-positive colonization showed no clinical manifestations. Conclusion: Maternal antibiotic consumption for more than 1 week is associated with the occurrence of oral thrush in breastfeeding infants. Differences in clinical signs in two groups of infants indicate the importance of laboratory tests for early oral thrush diagnosis. This can help health care professionals understand oral thrush causes, enable early detection, improve treatment, and enhance appropriate antibiotic use in breastfeeding mothers.

Upper Respiratory Drugs: Antitussives, Expectorants, and Mucolytics

Respiratory symptoms, such as congestion and cough, commonly accompany respiratory tract conditions. Various medications, such as antitussives, expectorants, and mucolytics, play crucial roles in providing relief.
Antitussives include codeine, dextromethorphan (Robitussin), and benzonatate (Tessalon). Codeine and dextromethorphan exert their effects centrally by suppressing the cough reflex center in the medulla.  Benzonatate operates peripherally within the respiratory tract by...

Factors Affecting the Risk of Infection01:26

Factors Affecting the Risk of Infection

The hosts' susceptibility to infection depends on several factors. The integrity of the skin and mucous membranes helps protect the body against microbial attacks. When the skin is altered, the chance of infection, limb loss, and even death increases.
The integrity and count of the white blood cells help the body resist pathogens and fight infection. When impaired, it reduces the body's resistance to pathogens. The acidic pH levels of the gastrointestinal, genitourinary tracts, and skin...

Development of Immunocompetence

The initiation of cell-mediated immunity can be observed as early as the third month of fetal growth, with active antibody-mediated immunity following approximately one month later.
The initial cells that migrate from the fetal thymus settle within the skin and epithelial tissues lining the mouth, digestive tract, and in females, the uterus and vagina. These cells, including skin-based dendritic cells, serve as antigen-presenting cells, playing a key role in T cell activation.
Subsequent T...
