Objective: To evaluate the use of off-label and unlicensed medications in preterm infants hospitalized in a neonatal intensive care unit., Methods: This nonconcurrent cohort study included preterm infants admitted to 3 neonatal intensive care units in 2016 and 2017 who were followed up during the neonatal period. The type and number of medications used were recorded for the entire period and classified based on the Anatomical Therapeutic Chemical. Descriptive and bivariate data analyses were performed to assess associations between the number of drugs used (total, off-label and unlicensed) and the explanatory variables of interest., Results: Four hundred preterm infants received 16,143 prescriptions for 86 different pharmaceuticals; 51.9% of these medications were classified as off-label and 23.5% as unlicensed. The most prescribed drugs were gentamicin and ampicillin (17.5% and 15.5% among off-label, respectively) and caffeine (75.5% among unlicensed). The results indicated significant associations between the use of off-label drugs and lower gestational age, low birth weight, lower 5-minute Apgar score, advanced resuscitation maneuver in the delivery room and death. The prescription of unlicensed drugs was associated with lower gestational age, low birth weight and 5-minute Apgar score below 7., Conclusion: Neonates admitted to neonatal intensive care units are highly exposed to off-label and unlicensed medications. Further studies are needed to achieve greater safety and quality of drug therapy used in neonatology.

The aim of this study was to evaluate the antiplaque effect of Ocimum gratissimum (Og) by in vivo investigation. Fifteen healthy volunteers participated in a crossover, double-blind clinical study, using a 3-day partial-mouth plaque accumulation model. The participants abolished any method of mechanical oral hygiene and they were randomly assigned to initially use just the following mouthrinses: distilled water (DW solution), 0.12% chlorhexidine digluconate (CLX solution) or 10% Og (Og solution). The plaque index (PLI) was recorded in all mandibular teeth at the end of the trial and the Kruskal-Wallis (α=0.05) and Mann-Whitney (α=0.05) tests were used to estimate the difference among groups. The clinical results showed statistically significant difference among the groups (p<0.05), favoring the CLX solution and Og solution, but the first was more effective (p<0.05). The mouthrinses containing 0.12% chlorhexidine digluconate and 10% Og were able to inhibit plaque re-growth, however Og showed more limited results in comparison to CLX.

Objective: To study the factors that influence the perception of acute pain and the consequences of this experience in patients suffering from mild trauma., Method: Descriptive qualitative study conducted in an emergency service in southern Brazil. Data was collected in October 2013, through semi-structured interviews with 29 individuals who reported pain after physical trauma, regardless of the triggering factor. To process the data, we used a Content Analysis technique, subject modality., Results: Two categories emerged: Factors that influence the perception of pain resulting from trauma and, Consequences of acute pain due to trauma. The acute pain sensation was influenced by biological, emotional, spiritual and socio-cultural factors and induced biological and emotional consequences for individuals., Conclusion: The health professionals need to consider the factors that influence soreness and its consequences for the proper assessment and management of pain resulting from trauma.

Purpose: It was to determine the prevalence of Chlamydia trachomatis and the risk factors associated with infection in endocervical specimens from women seen in outpatient Obstetrics and Gynecology., Methods: Samples of endocervical secretion of 200 women treated at the University Hospital of the Federal University of Rio Grande were analyzed for the presence of C. trachomatis by polymerase chain reaction (PCR) using primers that amplify CT05/CT06 281 base pairs of the main outer membrane protein of C. trachomatis. All participants completed a pre-coded and self-report questionnaire. Data were analyzed with the SPSS 17.0 software; for multivariate analysis it was used Poisson regression., Results: Of the 200 women who were included in the study, the prevalence of infection with C. trachomatis was 11% (22 patients) and these 55 (27.5%) were positive for HPV. Risk factors associated with infection by C. trachomatis were: 8 years or less of schooling (p<0.001), family income below the poverty level (p=0.005), first intercourse at age 15 or less (p=0.04) and being a carrier of the virus HIV (p<0.001). After multivariate analysis, only the variables of schooling or less than eight years (PR 6.0; 95%CI 1.26 - 29.0; p=0.02) and presence of HIV (RP 14.1; 95%CI 3.4 - 57.5; p<0.001) remained statistically significant., Conclusions: The prevalence of C. trachomatis in endocervical specimens by PCR was 11%. The factors associated with a higher infection by C. trachomatis were lower education and being HIV positive.

Purpose: To determine the HPV prevalence and genotypes and to identify factors associated with infection in pregnant and non-pregnant women with positive or negative HIV-1, treated in Gynecology and Obstetrics Ambulatories and in Health Primary Units, in Rio Grande, Rio Grande do Sul State, Brazil., Methods: Cervical cells samples from 302 patients were analyzed for HPV presence and genotypes were determined by nested and sequencing polymerase chain reaction. We calculated prevalence ratios associated with the studied variables by Fisher's exact or χ² tests, and Poisson's regression. Women with insufficient material were excluded from the study., Results: HPV was detected in 55 of the 302 women included in the study (18.2%); of these, 31 were pregnant, showing a significant association for HPV (p=0.04) when compared to non-pregnant ones. Risk factors for the infection were: patients aged <20 years-old (p=0.04), early initiation of sexual life (p=0.04), absence of cytological test (p=0.01), diagnosis of altered cytology (p=0.001), and counting <349 cells/mm³ (p=0.05). However, multi-parity was found to be a protective factor for the infection (p=0.01). Multivariate analysis showed that age <20 years-old (PR=2.8; 95%CI 1.0 - 7.7, p=0.04) and an altered cytological result (PR=11.1; 95%CI 3.0 - 4.1, p=0.001) were significantly associated with infection. HPV genotype was determined in 47 samples (85.4%) presenting one genotype per infection: eight HPV 16 and 58; six HPV 6; four HPV 18 and 33; three HPV 53 and 82; two HPV 83 and 61; one HPV 31, 35, 45, 64, 68, 71 and 85., Conclusions: The prevalence of HPV detection was 18.2%, the most frequent genotypes were 16 and 58, and sociodemographic and gynecological factors were associated with viral infection.
