RESUMO Objetivo: Avaliar o efeito da dilatação da pupila sobre a pressão intraocular em recém-nascidos pré-termo e a termo. Métodos: Este estudo prospectivo envolveu 55 olhos de 28 bebês pré-termo e 38 olhos de 20 bebês a termo. Os bebês foram divididos em dois grupos, pré-termo e a termo, de acordo com a idade gestacional ao nascimento: grupo pré-termo <37 semanas; grupo a termo ≥37 semanas. A dilatação da pupila foi feita com tropicamida 0,5% e fenilefrina 2,5%. As medições da pressão intraocular foram realizadas com Icare PRO (Icare Finland Oy, Helsinki, Finlândia) antes e depois da dilatação da pupila. O teste t pareado foi usado para comparar as medidas antes e depois da dilatação da pupila. Resultados: A alteração média da pressão intraocular foi de -1,04 ± 3,03 mmHg (+6,20/-11,40 mmHg) no grupo pré-termo e -0,39 ± 2,81 mmHg (+4,60/-9,70 mmHg) no grupo a termo. Uma diferença estatisticamente significativa na pressão intraocular foi observada apenas no grupo pré-termo após a dilatação da pupila (p=0,01). Conclusão: Após a dilatação da pupila, pode ocorrer alteração inesperada da pressão intraocular em recém-nascidos, principalmente em bebês pré-termo.

ABSTRACT Purpose: To evaluate the effect of pupil dilation on intraocular pressure in preterm and term newborns. Methods: This prospective study involved 55 eyes of 28 preterm infants and 38 eyes of 20 term infants. The infants were divided into two groups according to their gestational ages at birth as follows: preterm group, <37 weeks and term group, ≥37 weeks. Pupil dilation was attained with tropicamide 0.5% and phenylephrine 2.5%. Intraocular pressure measurements were performed with Icare PRO (Icare Finland Oy, Helsinki, Finland) before and after pupil dilation. A paired t test was used to compare the measurements before and after pupil dilation. Results: The mean intraocular pressure change was -1.04 ± 3.03 mmHg (6.20/-11.40 mmHg) in the preterm group and -0.39 ± 2.81 mmHg (4.60/-9.70 mmHg) in the term group. A statistically significant difference in intraocular pressure was observed only in the preterm group after pupil dilation (p=0.01). Conclusion: An unexpected alteration in intraocular pressure in newborns may occur after pupil dilation, especially in preterm infants.

SUMMARY: Most of the dental diseases occur due to tooth or jaw morphology or nutritional habits. Anatomical differences in the teeth and jaws of men and women can cause different dental diseases between the sexes. In this study, 33 skeletons obtained from the excavation of the ancient city of Parion, which are dated to the late Roman period, were examined. Dental diseases and possible causes were investigated on a total of 33 skeletons. In the evaluations, it was evaluated that some diseases were caused by the difference between the sexes, while some were classified as nutritional diseases. The rates of tooth decay are different between men and women with Parion. It has been determined that the most important reason for this is the different morphological structure of the jaws and teeth, but the nutritional differences also cause this. Other dental and jaw diseases were also evaluated in the Parion population.

RESUMEN: La mayoría de las enfermedades dentales se deben a la morfología de los dientes o la mandíbula o a los hábitos nutricionales. Las diferencias anatómicas en los dientes y las mandíbulas de hombres y mujeres pueden causar diferentes enfermedades dentales entre los sexos. En este estudio, se examinaron 33 esqueletos obtenidos de la excavación de la antigua ciudad de Parion, que datan del período romano tardío. Se investigaron las enfermedades dentales y las posibles causas en un total de 33 esqueletos. En las evaluaciones, se determinó que algunas enfermedades fueron causadas por la diferencia entre los sexos, mientras que otras fueron clasificadas como enfermedades nutricionales. Además se encontraron diferentes estimaciones de caries entre hombres y mujeres. Se analizó que la razón más importante de esto es la diferencia de la estructura morfológica de los maxilares y los dientes, sin embargo las diferencias nutricionales también es un factor que se debe considerar. Se evaluaron además, otras enfermedades dentales y de la mandíbula en la población de Parion.

Abstract Helicobacter pylori infection is usually acquired in early childhood and it can persist throughout life without antibiotic treatment. This study aimed to compare the accuracy of the noninvasive H. pylori Stool Antigen Test-applied on the stool samples with the invasive gold standart Rapid Urease Test-applied on the gastric biopy samples of patients with upper gastrointestinal complaints. After endoscopy, biopsy and stool specimens were taken in 122 patients. The infection was detected with rapid urease test which is accepted as gold standart test. Rapid, one-step H. pylori card test was applied to all patients stool specimens. In this study 106 of the 122 patients (86.8%) were positive for H. pylori infection, while 16 of the 122 patients (13.2%) were negative. H. pylori card test was negative in 13 of the 16 patients and was positive in 98 of the 106. The sensitivity, specifity, positive and negative predictive values were 92.45%, 81.25%, 97.02%, and 61.90%, respectively. H. pylori card test is rapid, easy, noninvasive and inexpensive methods for detection H. pylori infection. This test showed high sensitivity and specificity. Additionally, it may be a good alternative to invasive tests for the detection of H. pylori infections especially in children.
