Influence of etiologic factors in peri-implantitis: literature review and case report

Peri-implantitis is a pathology that has been described in many clinical studies and case reports. However, it is still not clear how the roles of its etiologic agents work. This article is based on a review of the literature and a case report. It aims to offer data related to the factors that cause this pathology, and to analyze how these factors interact, leading to the contamination of the peri-implant tissue.     

Short-term outcomes of Altis® single-incision sling procedure for stress urinary incontinence: a prospective single-center study

Introduction and hypothesis

Data on Altis® (Coloplast), a new adjustable single-incision sling (SIS) procedure for the treatment of female stress urinary incontinence (SUI), are scarce. Our aim was to evaluate the efficacy and complication rates of this procedure.

Methods

In this prospective observational study, a total of 52 women with SUI were implanted with an Altis® sling in an ambulatory setting. Before and after intervention (3, 6, and 12 months), women completed the International Consultation on Incontinence Questionnaire Short Form (ICIQ-SF). In addition, patients underwent a cough stress test at each evaluation and a post-voiding residual urine volume estimation at 3 months. The main outcomes measured were subjective cure (ICIQ-SF?=?0), subjective improvement (ICIQ-SF >0 and < preoperative ICIQ-SF), and objective cure (negative cough stress test and no pad usage) rates. De novo overactive bladder (OAB) symptoms, changes in voiding habits and adverse events were also analyzed.

Results

The subjective cure rate at 12 months was 84.0 %, with an additional improvement rate of 8.0 %. The objective cure rate was 90.2 %. Later postoperative complications included 1 case of vaginal extrusion (requiring surgical removal of the eroded mesh segment), 3 cases of vaginal exposure of the adjustment thread (managed conservatively), de novo urgency in 3 patients, and mild dyspareunia in 2 patients.

Conclusions

The Altis® sling is a safe and effective SIS procedure for the treatment of SUI with a short-term follow-up.     

A summary of economic evaluations published in the field of rheumatology and related disciplines

Introduction. The relationship between the effectiveness of health care interventions and their costs is of increasing interest. The goal of the present study was to summarize the economic evaluations (EEs) published in the field of rheumatology and related disciplines, and to focus in particular on methodologic issues. Methods. MEDLINE was searched in order to identify all relevant EEs published between 1966 and February 1995. Titles and abstracts of 1,435 articles were retrieved and independently reviewed by 2 assessors. Overall, 63 articles were identified by either assessor as being definite or possible full EEs (defined as an analysis comparing 2 or more strategies involving the assessment of both costs and consequences), and were assessed independently. Results. Thirty-six articles were determined to be full EEs (33 cost-effectiveness and 3 cost-utility analyses). Most were published in the periods 1984–1990 (31%) and 1991–1995 (61%). Main areas covered were methods of prevention (44%), treatment (31%), and treatment-prevention (22%). Disorders most frequently studied were osteoarthritis (36%), osteoporosis (22%), and rheumatoid arthritis (14%). Direct and indirect costs were measured or estimated in 100% and 28% of the EEs, respectively. The viewpoint of the analysis was stated explicitly in 12 studies (33%). Incremental and sensitivity analyses were presented in 17 (47%) and 23 (64%), respectively. Inadequate use of economic terms was also documented. Conclusion. The EE articles reviewed adhered partially to basic analytic methods. Economic evaluations in the field of rheumatology need to be improved to comply with current standards for the evaluation of health care interventions.     

Estratégias Econômicas e Sociais para Anticoagulação de Pacientes com Fibrilação Atrial

Background:Atrial fibrillation is a public health problem associated with a fivefold increased risk of stroke or death. Analyzing costs is important when introducing new therapies and must be reconsidered in special situations, such as the novel coronavirus pandemic of 2020.Objective:This study aimed to evaluate the costs related to anticoagulant therapy in a one-year period, and the quality of life of atrial fibrillation patients treated in a public university hospital.Methods:Patient costs were those related to the anticoagulation and calculated by the average monthly costs of warfarin or direct oral anticoagulants (DOACs). Patient non-medical costs (eg., food and transportation) were calculated from data obtained by questionnaires. The Brazilian SF-6D was used to measure the quality of life. P-values < 0.05 were considered statistically significant.Results:The study population consisted of 90 patients, 45 in each arm (warfarin vs direct oral anticoagulants). Costs were 20% higher in the DOAC group ($55,532.62 vs $46,385.88), and mainly related to drug price ($23,497.16 vs $1,903.27). Hospital costs were higher in the warfarin group ($31,088.41 vs $24,604.74) and related to outpatient visits. Additionally, non-medical costs were almost twice higher in the warfarin group ($13,394.20 vs $7,430.72). Equivalence of price between the two drugs could be achieved by a 39% reduction in the price of DOACs. There were no significant group differences regarding quality of life.Conclusions:Total costs were higher in the group of patients taking DOACs than those taking warfarin. However, a nearly 40% reduction in the price of DOACs could make it feasible to incorporate these drugs into the Brazilian public health system.     

In vitro evaluation of the susceptibility of endodontic pathogens to calcium hydroxide combined with different vehicles

The aim of this study was to investigate in vitro the antimicrobial activity of calcium hydroxide [Ca(OH)2] in combination with different vehicles against endodontic pathogens. For such purpose, a broth dilution test was performed. Pastes were prepared with Ca(OH)2 powder and the following vehicles: sterile water, glycerin, camphorated monochlorophenol (CMCP), CMCP + glycerin, polyethyleneglycol and CMCP + polyethyleneglycol. The time required for the pastes to produce negative cultures against the tested microorganisms was recorded and analyzed statistically using the Kruskal Wallis test at 5% significance level. Timing for pastes to eliminate the aerobic and facultative anaerobic microorganisms ranged from 6 to 24 h, while strict anaerobic microorganisms were inhibited within 30 s to 5 min. Microbial susceptibility, ranked from weakest to strongest, can be presented as follows: Enterococcus faecalis (the most resistant microorganism), Candida albicans, Staphylococcus aureus, Porphyromonas gingivalis, Porphyromonas endodontalis and Prevotella intermedia (the last two microorganisms required the same time to be eliminated). In conclusion, calcium hydroxide pastes needed more time to eliminate facultative than anaereobic microorganisms. These findings suggest that the antimicrobial property is related both to paste formulation and to microbial susceptibility.     

Type 1 diabetes mellitus associated or not with primary hypothyroidism and women’s fertility

Abstract

The aim of this study is to evaluate the prevalence of infertility and other reproductive parameters in women with type 1 diabetes mellitus (DM1) with and without primary hypothyroidism (PH). This is a cross-sectional study conducted at Division of Endocrinology. We evaluated 110 female, aged over 18 years, 79 had DM1 and 31 had DM1 plus PH. They were interviewed to obtain data on their gynecological and obstetric history; medical charts were reviewed to determine the characteristics of the diseases and to assess clinical/laboratory data. Infertility was defined as 12 months of unprotected sexual intercourse without conception. We used the chi-square and Mann–Whitney’s tests, and logistic regression analysis. The prevalence of infertility in the total sample was 24.5%, no differences were found between groups regarding obstetric outcomes and gynecologic variables. Factors associated with infertility were microvascular complication (OR: 11.36; 95% CI: 2.488–52.632; p?=?.029), polycystic ovary syndrome (OR: 9.80; 95% CI: 2.247–43.478; p?=?.016), PH (OR: 3.38; 95% CI: 1.078–10.638; p?=?.047), and older age at onset of DM1 (OR: 1.12; 95% CI: 1.029–1.215; p?=?.019). The presence of PH in women with DM1 was a predictive factor for infertility. Women with DM1 showed poorer reproductive outcomes compared to the general population.
