Review
OBJECTIVES
To evaluate the effect of subgingival administration of various antimicrobials and host-modulating agents in furcation defects as an adjunct to scaling and root planing (SRP) compared to SRP alone or combined with placebo.
METHODS
A systematic review was carried out using MEDLINE-PubMed, Embase, and Scopus for articles up to October 2022 in addition to hand searches. All longitudinal studies that evaluated the effect of subgingival application of antimicrobial and host-modulating agents in furcation defects as adjuncts to SRP compared to SRP alone or SRP + placebo with at least 3 months of follow-up were eligible for inclusion.
RESULTS
A total of eight studies were included. Superior clinical treatment outcomes were shown when alendronate, rosuvastatin, boric acid, simvastatin, and tetracycline (only at 3 months) were utilized in furcation defects in conjunction with SRP alone or SRP + placebo. Significant improvement was reported in radiographic bone defect depth and defect depth reduction when SRP was supplemented with alendronate, rosuvastatin, boric acid, and simvastatin.
CONCLUSIONS
Within the limitations of this review, the adjunctive subgingival administration of medications and host-modulating agents in furcation defects may confer additional clinical and radiographic benefits than non-surgical periodontal treatment alone. Future investigations are needed to confirm their long-term effectiveness.
CLINICAL RELEVANCE
Local host modulators and antimicrobials may be used supplementary to enhance the clinical and radiographic treatment outcomes of conventional periodontal therapy in furcation defects.

Review
BACKGROUND
Uveitis is a term used to describe a group of intraocular inflammatory diseases. Uveitis is the fifth most common cause of vision loss in high-income countries, with the highest incidence of disease in the working-age population. Corticosteroids are the mainstay of treatment for all subtypes of non-infectious uveitis. They can be administered orally, topically with drops, by periocular (around the eye) or intravitreal (inside the eye) injection, or by surgical implantation.
OBJECTIVES
To determine the efficacy and safety of steroid implants in people with chronic non-infectious posterior uveitis, intermediate uveitis, and panuveitis.
SEARCH METHODS
We searched CENTRAL (which contains the Cochrane Eyes and Vision Trials Register), MEDLINE Ovid, Embase, PubMed, LILACS, and three trials registries to November 2021. SELECTION CRITERIA: We included randomized controlled trials comparing either fluocinolone acetonide (FA) or dexamethasone (DEX) intravitreal implants with standard-of-care therapy or sham procedures, with at least six months of follow-up after treatment. We included studies that enrolled participants of all ages, who had chronic non-infectious posterior uveitis, intermediate uveitis, or panuveitis with vision that was better than hand-motion.
DATA COLLECTION AND ANALYSIS
We applied standard Cochrane methodology.
MAIN RESULTS
We included data from four trials (683 participants, 907 eyes) that compared corticosteroid implants with either sham or standard-of-care therapy. Study characteristics and risk of bias Of the two trials that compared corticosteroid implants with sham procedure, one examined a 0.18 mg FA implant, and the other, a 0.7 mg DEX implant. The other two trials compared a 0.59 mg FA implant with standard-of-care therapy, which included systemic corticosteroids and immunosuppressive medications, if needed. We assessed the four trials to be at either low risk, or with some concerns of risk of bias across all domains. Findings Using sham procedure as control, combined results at the six-month primary time point suggested that corticosteroid implants may decrease the risk of uveitis recurrence by 60% (relative risk [RR] 0.40, 95% confidence interval [CI] 0.30 to 0.54; 2 trials, 282 participants; low-certainty evidence); and lead to a greater improvement in best-corrected visual acuity (BCVA; mean difference [MD] 0.22 logMAR, 95% CI 0.13 to 0.31; 1 trial, 153 participants; low-certainty evidence). Evidence based on a single-study report (146 participants) suggested that steroid implants may have no effects on visual functioning quality of life, measured on the National Eye Institute 25-Item Visual Function Questionnaire (MD 2.85, 95%CI -3.64 to 9.34; 1 trial, 146 participants; moderate-certainty evidence). Using standard-of care therapy as control, combined estimates at the 24-month primary time point suggested that corticosteroid implants were likely to decrease the risk of recurrence of uveitis by 54% (RR 0.46, 95% CI 0.35 to 0.60; 2 trials, 619 eyes). Combined estimates at 24 months also suggested that steroid implants may have little to no effects on BCVA (MD 0.05 logMAR, 95% CI -0.02 to 0.12; 2 trials, 619 eyes; low-certainty evidence). Evidence based on a single-study report (232 participants) suggested that steroid implants may have minimal clinical effects on visual functioning (MD 4.64, 95% CI 0.13 to 9.15; 1 trial, 232 participants; moderate-certainty evidence); physical functioning (SF-36 physical subscale MD 2.95, 95% CI 0.55 to 5.35; 1 trial, 232 participants; moderate-certainty evidence); or mental health (SF-36 mental subscale MD 3.65, 95% CI 0.52 to 6.78; 1 trial, 232 participants; moderate-certainty evidence); but not on EuroQoL (MD 6.17, 95% CI 1.87 to 10.47; 1 trial, 232 participants; moderate-certainty evidence); or EuroQoL-5D scale (MD 0.02, 95% CI -0.04 to 0.08; 1 trial, 232 participants; moderate-certainty evidence). Adverse effects Compared with sham procedures, corticosteroid implants may slightly increase the risk of cataract formation (RR 2.69, 95% CI 1.17 to 6.18; 1 trial, 90 eyes; low-certainty evidence), but not the risk of cataract progression (RR 2.00, 95% CI 0.65 to 6.12; 1 trial, 117 eyes; low-certainty evidence); or the need for surgery (RR 2.98, 95% CI 0.82 to 10.81; 1 trial, 180 eyes; low-certainty evidence), during up to 12 months of follow-up. These implants may increase the risk of elevated intraocular pressure ([IOP] RR 2.81, 95% CI 1.42 to 5.56; 2 trials, 282 participants; moderate-certainty evidence); and the need for IOP-lowering eyedrops (RR 1.85, 95% CI 1.05 to 3.25; 2 trials, 282 participants; moderate-certainty evidence); but not the need for IOP-lowering surgery (RR 0.72, 95% CI 0.13 to 4.17; 2 trials, 282 participants; moderate-certainty evidence). Evidence comparing the 0.59 mg FA implant with standard-of-care suggested that the implant may increase the risk of cataract progression (RR 2.71, 95% CI 2.06 to 3.56; 2 trials, 210 eyes; low-certainty evidence); and the need for surgery (RR 2.98, 95% CI 2.33 to 3.79; 2 trials, 371 eyes; low-certainty evidence); along with the risk of elevated IOP (RR 3.64, 95% CI 2.71 to 4.87; 2 trials, 605 eyes; moderate-certainty evidence); and the need for medical (RR 3.04, 95% CI 2.36 to 3.91; 2 trials, 544 eyes; moderate-certainty evidence); or surgical interventions (RR 5.43, 95% CI 3.12 to 9.45; 2 trials, 599 eyes; moderate-certainty evidence). In either comparison, these implants did not increase the risk for endophthalmitis, retinal tear, or retinal detachment (moderate-certainty evidence). AUTHORS' CONCLUSIONS: Our confidence is limited that local corticosteroid implants are superior to sham therapy or standard-of-care therapy in reducing the risk of uveitis recurrence. We demonstrated different effectiveness on BCVA relative to comparators in people with non-infectious uveitis. Nevertheless, the evidence suggests that these implants may increase the risk of cataract progression and IOP elevation, which will require interventions over time. To better understand the efficacy and safety profiles of corticosteroid implants, we need future trials that examine implants of different doses, used for different durations. The trials should measure core standard outcomes that are universally defined, and measured at comparable follow-up time points.

STATEMENT OF THE PROBLEM
Bone morphogenetic protein (BMP), a potential osteoinductive agent, was systematically reviewed for merits and demerits when used as a bone additive that was intervened during the surgical phase of dental implant placement; and suitable drug carriers that could withstand the functional load and deliver BMP at its lowest concentration.
PURPOSE
To identify the carriers and concentration of BMP acceptable during surgical phase of implant placement and evaluate its efficacy in bone gain and osseointegration.
MATERIALS AND METHOD
The study design was systematic review. Literature search as per PICO format was carried out within a time range from 2000 to July 2021. The review fol-lowed PRISMA guidelines and registered with the PROSPERO (CRD42020171667). The focus question included the population with an intra-oral implant placed in both animal and human models that were intervened with BMP-2 as an external additive biomaterial during the surgical phase. 2631 articles selected from the initial search were systematically filtered and yielded 16 articles that were qualitatively analysed.
RESULTS
The inter-rater reliability and level of agreement were 93.71%, κ(Kappa)>0.81 re-spectively. Results revealed the collagen carrier was commonly used for BMP delivery but lacked the property to withstand functional load and sustained release. BMP concentration varied in the range of 0.215μg to 0.8mg and the study revealed significantly indifferent out-come with low dose compared to the highest dose. BMP supplement showed better osseointe-gration in comparison with non-supplemented sites during the early period (within 6 months).
CONCLUSION
BMP at lower concentrations and with appropriate carriers, collagen sponge, hydroxyapatite/tricalcium phosphate (HA/TCP) with a bio ceramic bulking agent, and poly (D, L-lactide-co-glycolic acid) (PLGA) reinforced with gelatin/HA/TCP accelerated bone growth during the initial stages of healing. Further long-term clinical trials for dental implant, analysing the sustained release of BMP with biodegradable and load-bearing carriers should be considered.

Meta-Analysis Review
BACKGROUND
There is a growing body of human, animal and in vitro studies on vitamin D (vit D) substitution in endometriosis. The aim of this systematic review is to critically appraise and qualitatively synthesize the results of the available studies that examine the supplementation of vit D for endometriosis treatment.
METHODS
A systematic search of the literature was conducted in four electronic databases (Medline, Cochrane, Scopus, Embase) and grey literature for original research articles on humans, animals and in vitro models published in any language.
RESULTS
Four human studies, four animal studies and four in vitro studies were included. Quantitative synthesis of human studies showed no significant effect of vit D intake for dysmenorrhea (2 studies, 44 vit D vs 44 placebo, mean -0.71, 95% CI -1.94, 0.51) and non-cyclic pelvic pain (2 studies, 42 vit D vs 38 placebo, mean 0.34, 95% CI -0.02, 0.71). Regarding reproductive outcomes in women with endometriosis after in vitro fertilization, the only available study showed no differences between women taking vit D and women taking placebo. Three of the four included animal studies showed regression of endometriotic implants when treated with vit D. The in vitro studies demonstrated that vit D decreases invasion and proliferation of endometriotic lesions without affecting apoptosis.
CONCLUSIONS
Although in vitro and animal studies suggest regression of the endometriotic implants and decrease of invasion and proliferation after vit D supplementation, this was not reflected in the results of the meta-analysis, which showed no benefit of vit D supplementation in patients with endometriosis and dysmenorrhea or non-cyclic pelvic pain as well as on the outcome of IVF treatment. However, given the heterogeneity and the diversity of the available studies, more research is required to shed light on the role of vit D supplementation in women with endometriosis.

Review
: The aim of this systematic review was to assess the available evidence of using enamel matrix derivate in the treatment of peri-implantitis. : Three electronic databases (, , and ) were searched until August 2022 to identify relevant articles. The inclusion criteria consisted in human clinical studies that reported the use of enamel matrix derivate (EMD) in surgical and non-surgical treatment of peri-implantitis. The risk of bias was assessed using Cochrane risk of bias tool for randomized clinical trials (RCTs) and for non-RCTs ROBINS-I tool. : Clinical studies included were published between 2012 and 2022 and consisted of two randomized clinical trials (RCTs) for non-surgical therapy and two RCTs, three prospective cohort studies, and one retrospective case series in surgical therapy. Due to the heterogeneity of patients' characteristics and assessment of peri-implant therapy, statistical analysis could not be achieved. : The use of EMD indicated a positive effect on both surgical and non-surgical therapy. However, the available literature is scarce, with low evidence in non-surgical approach and modest evidence in surgical approach using EMD. More RCTs with standardize protocols are necessary to evaluate the efficacy of using EMD in both therapies.

Review
Erythropoietic protoporphyria (EPP) and X-linked protoporphyria (XLP) are characterized by skin photosensitivity caused by accumulation of protoporphyrin IX. We aimed to review the clinical evidence of efficacy and safety of skin photosensitivity treatments in individuals with EPP or XLP. We systematically searched MEDLINE, Embase, the Cochrane Library, and ClinicalTrials.gov. A total of 40 studies with data on 18 treatment modalities were included. Comprehensive treatment safety data were obtained from the European Medicines Agency and the United States Food and Drug Administration. The studies used different outcome measures to evaluate the sensitivity without a generally accepted method to assess treatment effect on skin photosensitivity. Of the included studies, 13 were controlled trials. Gathered, the trials showed moderate positive effect of inorganic sunscreen application and subcutaneous implant of afamelanotide and no effect of organic sunscreen application, or oral treatment with beta-carotene, cysteine, N-acetylcysteine, vitamin C, or warfarin. Studies without control groups suggested treatment effect of foundation cream, dihydroxyacetone/lawsone cream, narrow-band ultraviolet B phototherapy, erythrocyte transfusion, extracorporeal erythrocyte photodynamic therapy, or oral treatment with zinc sulphate, terfenadine, cimetidine, or canthaxanthin, but the real effect is uncertain. Assessment of treatment effect on photosensitivity in patients with EPP or XLP carries a high risk of bias since experienced photosensitivity varies with both weather conditions, exposure pattern, and pigmentation. Controlled trials of promising treatment options are important although challenging in this small patient population.

Review
The implementation of adjunctive antibiotics has been recommended for the therapy of peri-implantitis (PI). In this review, antibiotic resistance patterns in PI patients were assessed. A systematic scoping review of observational studies and trials was established in conjunction with the PRISMA extension for scoping reviews. The SCOPUS, PubMed/MEDLINE, EMBASE, SCIELO, Web of Science, and LILACS databases were reviewed along with the gray literature. The primary electronic examination produced 139 investigations. Finally, four observational studies met the selection criteria. These studies evaluated 214 implants in 168 patients. and mainly presented high resistance to tetracycline, metronidazole, and erythromycin in PI patients. Similarly, was also highly resistant to clindamycin and doxycycline. Other microorganisms such as , , and also presented significant levels of resistance to other antibiotics including amoxicillin, azithromycin, and moxifloxacin. However, most microorganisms did not show resistance to the combination amoxicillin metronidazole. Although the management of adjunctive antimicrobials in the therapy of PI is controversial, in this review, the resistance of relevant microorganisms to antibiotics used to treat PI, and usually prescribed in dentistry, was observed. Clinicians should consider the antibiotic resistance demonstrated in the treatment of PI patients and its public health consequences.

Review
Dental implants are prosthetic devices that are surgically placed in direct contact with the jawbone to support intra-oral functions and esthetics. Diabetes mellitus may contribute to peri-implant bone loss. During the last few years, there have been attempts to reduce this bone loss and improve the survival rate of implants. Metformin, an anti-diabetic drug known for its osteogenic properties, is thought to prevent peri-implant bone loss in diabetic patients. Although several studies have been conducted to study metformin's effect on diabetic and non-diabetic study models, no systematic review has analyzed and summarized these studies critically. Therefore, the objectives of this systematic review were to summarize the outcomes of these studies and critically appraise them. Seven studies were included in this systematic review. Four studies used only animal models, two used both animal and cell culture models, and one used only cell culture studies. The general characteristics and outcomes of the included studies were summarized, and Animal Research: Reporting of In Vivo Experiments (ARRIVE) guidelines were used to assess the quality of the animal studies. In vitro studies indicate that metformin may induce stem cells to undergo osteoblastic differentiation to produce a higher amount of bone and may also improve osseointegration. Nevertheless, several studies had potential sources of bias. Therefore, it is recommended that emphasis be placed on increasing the quality of future animal studies and human trials to determine the effects of metformin on the osseointegration of dental implants. Future studies are needed with adequate follow-up to evaluate the efficacy of metformin in improving the osseointegration of dental implants.

BACKGROUND
With the availability of several similar medical devices performing the same function, choosing one for reimbursement is not easy, especially if purchased for a large number of patients. The objective of this project was to create a multicriteria decision analysis (MCDA) tool, that captures and compares all implantable medical devices' attributes, to provide an objective method for choosing among the available options in Egypt.
METHOD
We conducted a systematic review and expert interviews, to identify the relevant criteria for inclusion in the tool. Subsequently, a workshop was conducted, that involved experts in procuring and tendering medical devices. Experts chose the criteria, ranked them, assigned weights and scoring functions for each criterion, and then created the draft tool. A pilot phase followed; then, another workshop was conducted to fine-tune the tool. We readjusted the tool based on experts' experience with the draft tool.
RESULTS
The final tool included eight criteria, arranged according to their weightage: technical characteristics (29.4%), country of origin (19.5%), use in reference countries (14.9%), supply reliability (11.7%), previous use in tenders (9.0%), instant replacement within product variety (6.9%), pharmacovigilance (4.6%), and refund or replacement (4.0%). Each medical device was assessed on these eight criteria to achieve a final score, that was compared to the alternative devices' scores. Price is not included in the MCDA tool, but it will be added in the financial evaluation phase.
CONCLUSION
Decisionmakers could use the MCDA tool, to make evidence-based and objective decisions for purchasing implantable devices, in the Egyptian public sector. Post price evaluation, the product with the best value will be chosen for reimbursement.
HIGHLIGHTS
We created an MCDA tool to help decision makers choose between alternative implantable medical devices in Egypt. The MCDA tool includes eight criteria, where price is evaluated as a separate step. "Technical characteristics" and "country of origin" criteria carried the highest weights, thus representing approximately 50% of the decision.

Meta-Analysis
Is bisphosphonate use a risk factor for atypical periprosthetic/peri-implant fractures? - A metanalysis of retrospective cohort studies and systematic review of the current evidence.
INTRODUCTION
Atypical periprosthetic/peri-implant fractures are not recognised in any widely used classification and therefore little focus is given to them. Multiple case reports and case series demonstrate these fractures exist and are related to bisphosphonate (BP) use.
HYPOTHESIS
Are patients taking long-term BPs at an increased risk of developing an atypical periprosthetic/peri-implant fracture? Is a particular BP drug causing an increased risk of fracture? Is there a correlation between the time of BP use and the incidence of fractures? Do vitamin D analogues or parathyroid hormones reduce the time to union?
MATERIAL AND METHODS
Systematic review of all available evidence on the existence of periprosthetic/peri-implant atypical fractures in patients taking long-term BPs and metanalysis of available retrospective cohort studies. Selected 1 systematic review, 7 retrospective cohort studies (5 used for metanalysis) and 32 case reports.
RESULTS
Metanalysis reported a risk ratio of 14.1, p=0.25, suggesting bisphosphonates are a risk factor in the development of periprosthetic/peri-implant atypical fractures. The secondary outcomes couldn't be reliably identified due to the small size of available studies and risk of significant bias.
DISCUSSION
Atypical periprosthetic/peri-implant fractures are an entity and seem to be associated with the use of bisphosphonates. The benefits of bisphosphonates use outweigh the risks, but clinicians should be aware of atypical fractures and actively search for them when patients on long-term bisphosphonates attend with non-specific pain close to the implant/prosthesis or reduced mobility.
