Tratamiento de maloclusión classe II división 1 con el aparato de Herbst tipo férula, después del pico de crecimiento puberal

Malocclusion class II-1, is represented by a high prevalence in Brazil, being something common in orthodontic practice. One of the main characteristics of this malocclusion is jaw retrusion, by what many devices of jaw advance are presented in the literature. Being one of them Herbst's device, which is a functional and fixed device created by Emil Herbst (1905) and updated by Hans Pancherz in the decade of 80s.This device is characterized by keeping the jaw advance in a continuous way, while presenting a less active treatment, leading to an immediate aesthetic impact, and the patient cooperation is not required. To improve the anchoring and prevent the collapse of the apparatus was set up last amended version of it by Dr Raveli quoted as Herbst splint. Recent research indicates the use of this device after the peak pubertal growth, creating an appropriate response condylar. The aim of this work is to show the orthodontist a choice of how to use the splint Herbst in Class malocclusions II-1.

Microorganisms in the female genital tract during pregnancy: tolerance versus pathogenesis

Microorganisms in the pregnant female genital tract are not always associated with pathology. The factors that influence the maternal response to microorganisms remain ill defined. We review the state of knowledge of microbe-host interactions in gestational tissues and highlight mechanisms that promote tolerance or pathogenesis. Tolerance to microorganisms is promoted during pregnancy by several mechanisms including upregulation of anti-inflammatory mediators, induction of endotoxin tolerance, and possibly by regulation of autophagy. Conversely, an altered vaginal microbiota or a pre-existing viral presence may result in induction of excessive inflammation and preterm labor. Although infections play a prevalent role in preterm birth, microbes are present in gestational tissues of women with healthy outcomes and may provide beneficial functions. The complex interactions between different microbial species and the maternal immune system during gestation remain incompletely elucidated.

Association between concurrent genital bleeding and cervical cancer: a cross-sectional study

Genital bleeding may be a common symptom among women with cervical cancer. Cross-sectional study evaluating whether the prevalence of cervical smear results is different in women with and without clinical information about concurrent genital bleeding. The sample consisted of 2 324 836 smears; of these, 0.4% had clinical information on genital bleeding. When stratified by age group, women with genital bleeding had a higher chance of a cytological result of a high-grade squamous intraepithelial lesion [30-49 years odds ratio (OR) 2.38; 95% confidence interval (CI) 1.60-3.53 and ≥50 years OR 6.30; 95%CI 3.72-10.67), of squamous cell carcinoma (SCC) (30-49 years OR 24.70; 95%CI 11.96-51.03 and ≥50 years OR 48.91; 95%CI 31.28-76.47) and of atypical glandular cells (30-49 years OR 5.72; 95%CI 3.30-9.93 and ≥50 years OR 11.56; 95%CI 5.96-22.45); there was also a higher chance of adenocarcinoma for women ≥50 years (OR 53.13; 95%CI 28.08-100.51). The sensitivity of genital bleeding for women aged 18-29 years was 0.4% for high-grade squamous intraepithelial lesion (HSIL); for women 30-49 years old the rate was 0.9% for HSIL, 8.6% for SCC and 2.1% for atypical glandular cells of undetermined significance (AGUS), while for women aged from 50 years or more the rates were 2.0% for HSIL, 13.7% for SCC, 3.6% for AGUS and 14.7% for adenocarcinoma. Women ≥30 years old with genital bleeding should be referred for colposcopy to rule out the possibility of cervical cancer.

Estúdio Ghibli: um aparato sobre as técnicas ilustrativas e filosofia oriental dos principais longas metragens de Hayao Miyazaki

In front of the vast and widespread use of new technology in 3D animation currently, this research aims to give an overview adjacent to major film productions with Studio Ghibli and its main director/animator: Hayao Miyazaki. Showing up as an interesting exception to worldwide success, the Ghibli feature films are made with the predominance of 2D hand-drawn art. Its process dates back to the first animations created in the early twentieth century, though such tools have been “overcome” by big studios like Walt Disney, Pixar and Dreamworks, the works of Miyazaki still get considerable highlight, preferring the pencil and paper than the computer. With the aid of some authors in particular as McCloud and the founders of Anima Mundi, and other theorists of design and subjective philosophy, some analyzes are mapped to better understand the connection between the work of Miyazaki and his contribution to the field of illustration and originality as a whole. The objective is to find the key points of Ghibli animations which will drive new parameters between creativity, illustration and Western and Eastern praxis.

Genital infections of HIV-infected women assisted by a specialized service

The present study aimed at analyzing the persistence/recurrence of genital infections and its associated factors in HIV-infected women. Fifty-eight women treated for chlamydial infection, trichomoniasis, vulvovaginal candidiasis, and/or bacterial vaginosis (BV) and who had specimens collected for cure control up to one year after treatment were studied. Diagnoses were performed by the Gram staining method for cases of BV and candidiasis and by T. vaginalis culture and qualitative PCR for C. trachomatis. Antiretroviral therapy was used by 79.3% of patients, and 62.1% showed an undetectable HIV plasma load. The most frequent infection was BV with persistence/recurrence of 52.4%, which was associated with a longer time period between treatment and cure control (P = 0.0455), postmenopausal period (P = 0.0451), and having a steady partner (P = 0.007). Persistence/recurrence of vulvovaginal candidiasis was observed in 25%, trichomoniasis in 23.1%, and chlamydial infection in 10.5%. The letter was associated with inadequate treatment of the partner (P = 0.073) among patients with low T CD4 lymphocyte counts. The majority of women in the present study showed good HIV-infection control and a vulnerable sexual behavior, which stress the importance of maintaining gynecological followup.
