ABSTRACT
BACKGROUND: As enamel and finger buds have an ectodermal origin and grow at the same time, it might be supposed that factors and agents that affect dental caries might give rise to the diversity of dermatoglyphic dermal ridge patterns. AIM: The present study aimed to evaluate the relationship between dental caries and dermatoglyphics in 3 to 6-year-old Iranian children. METHODS: The present case-control study was performed on 3 to 6-year-old children. The decayed, missing, and filled teeth (dmft) scale was used to evaluate the oral and dental health status in the participants. Then, the patients were divided into two groups: 1) The case group: patients with a dmft of ≥3 (101 cases); 2) the control group: those with dmft value of zero (86 cases). Afterward, using a fingerprint recording device, the fingerprints were obtained from both hands of the participants. RESULTS: There was no significant relationship between the patterns of fingerprints and dental caries. The percentages of whorls, loops, and arches in the case group were higher than those in the control group; however, these differences were not statistically significant. CONCLUSION: Dermatoglyphic patterns could not be used as a variable for the detection or prediction of dental caries in Iranian children.

Coagulase-negative staphylococci (CoNS) are recognized as comprising the main part of human normal microbiota and are rarely associated with severe and intensive infections. However, these organisms can cause a number of infections in humans, especially immunocompromised patients and neonates. Bacterial meningitis, as an important and acute infection in the central nervous system, is still a major global health challenge and a serious infectious disease, causing a high rate of mortality and morbidity. CoNS as causative agents of meningitis are generally related to trauma or direct implantation of foreign bodies and the presence of a cerebrospinal fluid shunt. Numerous epidemiologic and clinical studies have shown that different CoNS isolates such as Staphylococcus capitis, Staphylococcus lugdunensis, Staphylococcus hominis, Staphylococcus epidermidis, Staphylococcus schleiferi, Staphylococcus saprophyticus, Staphylococcus warneri and Staphylococcus haemolyticus are more frequently associated with meningitis. This study attempts to determine the role of CoNS in meningitis and reviews the reported cases of meningitis induced by CoNS from the year 2000 to 2020 in the literature.
