Post-extubation atelectasis in newborns with surgical diseases: a report of two cases involving the use of a high-flow nasal cannula.

Atelectasis is a pulmonary disorder that lengthens the hospitalization time of newborns in intensive care units, resulting in increased morbidity among these infants. High-flow nasal cannulae have been used in newborns to prevent atelectasis and/or expand pulmonary regions affected by atelectasis; however, to date, no evidence-based data regarding this approach have been reported. In this paper, we report on the cases of two male newborn patients.

Very low and low birth weight associated with maternal periodontitis.

Aim: The aim of this study was to evaluate the association of very low and low birth weight (VLBW and LBW) with maternal periodontitis.

Material And Methods: Overall, 1206 women were examined at post-partum and two alternative criteria for periodontitis definition were used: (1) four or more teeth with at least one site with probing depth (PD) ≥ 4 mm and clinical attachment loss (CAL) ≥ 3 mm; and (2) at least one site with PD and CAL ≥ 4 mm. For each definition, two multivariate analyses were performed: (1) linear regression for birth weight; (2) ordinal logistic regression for birth weight, categorized as adequate (n = 1046), LBW (n = 145) and VLBW (n = 15).

Indatraline: synthesis and effect on the motor activity of Wistar rats.

A new approach for the synthesis of indatraline was developed using as the key step an iodine(III)-mediated ring contraction of a 1,2-dihydronaphthalene derivative. Behavioral tests were conducted to evaluate the effect of indatraline and of its precursor indanamide on the motor activity of Wistar rats. Specific indexes for ambulation, raising and stereotypy were computed one, two and three hours after i.

Maternal periodontal disease and preterm or extreme preterm birth: an ordinal logistic regression analysis.

Background: Despite previous studies addressing the link between preterm or low birth weight infants and maternal periodontitis, extreme preterm births have received far less attention. This study is designed to address the possible association between maternal periodontal disease and preterm or extreme preterm birth.

Methods: Immediately after childbirth, 1,207 women underwent an examination in which periodontal disease was assessed according to two alternative definitions: 1) four or more teeth with at least one site showing probing depth (PD) >or=4 mm and clinical attachment loss (AL) >or=3 mm, and 2) at least one site showing PD and clinical AL >or=4 mm.

[Correlation between clinical examination, mammography and ultrasonography with histopathological exam in the determination of tumor size in breast cancer].

Purpose: to evaluate which method is the best to determine pre-surgically the size of breast cancer: clinical examination, mammography or ultrasonography, using as a reference the anatomopathological exam.

Methods: this study has included 184 patients with palpable-or-not breast lesions, detected by mammography and ultrasonography, that were submitted to surgical resection of the tumor, with histopathological diagnosis of breast cancer. The same examiner evaluated clinically the largest tumoral diameter, through clinical examination, mammography and ultrasonography, and the measurements obtained by each method were correlated with the maximum diameter obtained by the anatomopathological exam.

Maternal periodontitis as a potential risk variable for preeclampsia: a case-control study.

Background: Association studies between maternal periodontitis and an elevated risk for preeclampsia have shown conflicting results. The aims of the present case-control study were: 1) to evaluate the association between maternal periodontitis and preeclampsia before and after matching, assessing confounding and interaction; and 2) to evaluate the influence of the extent and severity of periodontal parameters, bleeding on probing (BOP), probing depth (PD), and clinical attachment loss (CAL), in association with preeclampsia.

Methods: Initially, 1,206 Brazilian women were included and divided into a control group (1,042 non-preeclamptic women who gave birth to infants with adequate gestational age and birth weight) and a case group (164 preeclamptic women).

Gingival overgrowth in renal transplant subjects medicated with tacrolimus in the absence of calcium channel blockers.

Background: The results from reports analyzing the occurrence of gingival overgrowth (GO) induced by tacrolimus are controversial. In addition, the role of pharmacological and periodontal variables on the development and severity of GO have not been well-established. Therefore, the aim of the present study was to determine the effect of potential risk variables for GO in a Brazilian population comprising renal transplant recipients medicated with tacrolimus in the absence of calcium channel blockers.

Intrauterine growth restriction, low birth weight, and preterm birth: adverse pregnancy outcomes and their association with maternal periodontitis.

Background: It has been suggested that periodontitis is associated with systemic alterations such as adverse pregnancy outcomes. However, some conflicting results have been reported. This case-control study was conducted to determine the association between maternal periodontitis and preterm birth (PTB), low birth weight (LBW), and intrauterine growth restriction (IUGR).

Iodine(III)-promoted ring contraction of 1,2-dihydronaphthalenes: a diastereoselective total synthesis of (+/-)-indatraline.

[reaction: see text] A new approach for the synthesis of (+/-)-indatraline, which is a 3-phenyl-1-indanamine that displays several biological activities, is described. The strategy features as the key step a diastereoselective ring contraction of a 1,2-dihydronaphthalene promoted by PhI(OTs)OH, to construct the indan ring system. The oxidative rearrangement of other 1,2-dihydronaphthalenes was also investigated, generalizing this method to obtain indans.
