The use of arthrocentesis in patients with temporomandibular joint disc displacement without reduction.

The aim of this study was to evaluate the efficacy of the use of the arthrocentesis in patients with disc displacement without reduction (DDWOR). Two hundred and thirty-four (234) patients with DDWOR were evaluated and the following data collected: gender; affected side; age (years); duration of the pain (months); patient's perception of pain (measured by Visual Analogue Scale [VAS 0-10]); maximal interincisal distance (MID) (mm); and joint disc position, determined by magnetic resonance imaging. Data were obtained in two different moments: before the arthrocentesis (M1) and three or four months later (M2).

Myofascial trigger points in patients with temporomandibular joint disc displacement with reduction: a cross-sectional study.

Objective: The objective of this retrospective study was to evaluate the impact of myofascial trigger points (MTrPs) in patients with articular disc displacement with reduction (DDWR) and to identify which clinical variables are associated with the concomitant presence of DDWR and MTrPs.

Material And Methods: 130 patients were selected that sought treatment due to joint pain, with ages ≥18 years, of both genders, with DDWR confirmed by magnetic resonance imaging. The sample was divided into two groups: Group 1, patients with DDWR and MTrPs (N=101); and Group 2, patients with DDWR and no MTrPs (N=29).

Objectives: The aim of this study was to investigate the preoperative variables in patients with articular disk displacement without reduction that may influence the results of arthrocentesis on joint effusion (JE).

Study Design: The records of 203 patients with clinical signs and symptoms of unilateral painful disk displacement without reduction and JE, confirmed by magnetic resonance imaging (MRI), and treated with arthrocentesis were selected. The following preoperative data were recorded: sex; age; joint side; pain duration; pain intensity, measurement with the visual analogue scale; and maximum interincisal distance (MID).

B2-kinin receptors in the dorsal periaqueductal gray are implicated in the panicolytic-like effect of opiorphin.

Reported results have shown that the pentapeptide opiorphin inhibits oligopeptidases that degrade brain neuropeptides, and has analgesic and antidepressant effects in experimental animals, without either tolerance or dependency after chronic administration. In a previous study we showed that opiorphin has a panicolytic-like effect in the dorsal periaqueductal gray (dPAG) electrical stimulation test (EST), mediated by the μ-opioid receptor (MOR). This study further analyzes the mechanism of opiorphin panicolytic action, using the EST and drug injection inside the dPAG.

Qualitative Determination of Human Chorionic Gonadotropin in Vaginal Washings for the Early Diagnosis of Premature Rupture of Fetal Membranes.

 This study aimed to evaluate and validate the qualitative human chorionic gonadotropin β subunit (β-hCG) test of the vaginal fluid washings of pregnant women with premature rupture of fetal membranes (PROM).  Cross-sectional study of pregnant women between gestational weeks 24 and 39 who underwent consultations in one of our institutions. They were divided into two groups: group A (pregnant women clinically diagnosed with PROM) and group B (pregnant women without loss of amniotic liquid).

Insulin complexation with hydroxypropyl-beta-cyclodextrin: Spectroscopic evaluation of molecular inclusion and use of the complex in gel for healing of pressure ulcers.

The pressure ulcer healing is a complex process and difficult to be achieved. Insulin is known to promote wound healing, and when complexed with cyclodextrin presents improved solubility, stability and biological activity. Complexation of insulin with hydroxypropyl-beta-cyclodextrin (HPβCD) was performed in this work through the coprecipitation method, providing the inclusion complex (HPβCD-I).

Oral lesions and colonization by yeasts in hemodialysis patients.

Background: Patients with chronic kidney disease, stage 5, undergoing hemodialysis treatment are frequently colonized by yeasts, with high chance of developing fungal infections. The objective of this study was to assess the presence of yeasts in the oral cavity of these individuals, associating findings with the presence of oral lesions and the use of dental prostheses.

Methods: Clinical examinations of the oral mucosa were performed in 52 patients, when the use of removable dental prostheses and the presence of oral lesions were observed and recorded.

Color stability over time of three resin-based restorative materials stored dry and in artificial saliva.

Objective: To evaluate the color match of different composite resins relative to Vitapan Classical shade guide tab and their respective manufacturers' shade guide tabs as a function of time and storage.

Materials And Methods: Three enamel shade A2 composite resins were used to fabricate 36 disk-shaped polymerized specimens (12 each), allocated into 2 groups of 6 and stored dry (GD) and in artificial saliva (GS). CIELAB coordinates from shade tabs and resin specimens immediately after polymerization (t0), and 24 hours (t1), 7 (t7), 14 (t14) and 21 (t21) days after polymerization were captured using a colorimeter.

Risk factors for cervical HPV infection and genotypes distribution in HIV-infected South Brazilian women.

Background: Human Papillomavirus (HPV) infection is particularly burdensome for women infected with human immunodeficiency virus (HIV), which increases their risk of developing cervical lesions and cancer (CC). We conducted a molecular study of the distribution of cervical HPV genotypes and the risk factors for this infection in HIV-infected Brazilian women.

Findings: Cervical and endocervical samples for Papanicolaou screening and HPV detection were collected from 178 HIV-infected women using highly active antiretroviral therapy (HAART) of Maringá city/Brazil.

Hospital morbidity among elderly patients, before and after influenza vaccination in the state of Paraná.

This ecological study was developed to evaluate the patterns in hospital morbidity due respiratory diseases among people over 60 years old residing in the State of Paraná, before and after the implementation of vaccination campaigns against influenza.
