The aim of the present study was to investigate the clinical outcomes of two different standardized endodontic irrigation protocols. It was assumed that the additional use of ethylenediaminetetraacetate (EDTA) and passive ultrasonic irrigation (PUI) would result in an increased rate of absence of symptoms and remission based on the periapical index (PAI) compared to passive irrigation using only sodium hypochlorite (NaOCl). Data and radiographs from 199 teeth retrieved from the institutional endodontic database were analyzed retrospectively. In 106 teeth irrigation was performed using only NaOCl (protocol 1). Ninety-three teeth were irrigated using NaOCl and EDTA (protocol 2). Chlorhexidine (CHX) was additionally used in revision treatments in both groups. All irrigants in group 2 were activated by PUI. Mean follow-up periods were: protocol 1 = 9.2 ± 4.4 and protocol 2 = 6.6 ± 2.5 months (p < 0.0001 (chi-square test). The frequencies of the PAImasterpoint and PAIfollow-up scores did not differ significantly between teeth, which received either protocol 1 or 2 (p = 0.555 and 0.138). Statistical analysis revealed no significant association between treatment success (absence of clinical symptoms and PAIfollow-up = I or PAImasterpoint > PAIfollow-up > I) and the applied protocol (success rates: protocol 1 = 72.6% vs. protocol 2 = 82.8%; p = 0.203). Furthermore, the frequency of extractions did not differ significantly between the two protocols (p = 0.102). No association was found between follow-up time and treatment success (p = 0.888). The hypothesis was not confirmed. Even though the obtained success rate was higher after supplementing the irrigation protocol with EDTA and PUI, no significance was recorded. Hence, protocol 2 was not superior to protocol 1 regarding therapy success, at least within the limited follow-up period. It may be cautiously concluded that sufficient mechanical debridement combined with passive NaOCl irrigation results in comparably high success rates compared to EDTA and PUI.

Objective. The aim of this study was to evaluate and compare, both clinically and radiographically, the effects of calcium silicate-based materials (i.e., ProRoot MTA [PR-MTA], MTA-Plus [MTA-P], and Biodentine [BD]) and ferric sulfate [FS] in pulpotomy of primary molars. Materials and Methods. In this randomized clinical trial, 29 healthy 5- to 7-year-old children with at least four carious primary molars with no clinical or radiographic evidence of pulp degeneration were enrolled. The pulpotomy agents were assigned as follows: Group 1: BD; Group 2: MTA-P; Group 3: PR-MTA; and Group 4: FS. Clinical and radiographic evaluations were performed at 6, 12, and 24 months. Data were analyzed using chi-square tests. Results. Total success rates at 24 months were 82.75%, 86.2%, 93.1%, and 75.86%, respectively. No statistically significant differences in total success rates were observed among the groups at 6-, 12-, and 24-month follow-ups. When the groups were compared according to follow-up times, the success rates in each group did not vary significantly among the 6–12-month, 6–24-month, or 12–24-month periods (p>0.05). Conclusion. Although the success rates of BD, MTA-P, MTA-PR, and FS did not differ significantly, calcium silicate-based materials appeared to be more appropriate than FS in clinical practice.

Purpose: To compare lateral rectus recession (LRc) and medial rectus advancement (MRadv) for correction of consecutive exotropia (CXT). Methods: Of the 43 exotropic patients 20 of them underwent LRc (group 1) and 23 of them underwent MRadv (group 2). Postoperative exodrift, strabismic angle, dose effect relationship were compared with minimum 2 years follow‑up. Results: An average dose-effect in group 2 is higher than group 1 in the early postoperative period, however there was no significant difference at the second year follow-up (p=0,109). An average exodrift after 2 year follow-up was 6,6±7,12 PD in group 1, and 8,13±7,45 PD in group 2. Postoperative overall success rate was 50% in group 1 and 65% in group 2 at the last follow-up. The success rates were not significantly different between the groups (chi-square, p =0.31). Conclusion: Although there was no statistically significant difference at the last follow-up, better results were obtained with MRadv than LRc in the treatment of CXT.

ABSTRACT Objective: The aim of this study is to evaluate four different pulpotomy medicaments in primary molars. Materials and Methods: A total of 147 primary molars with deep caries were treated with four different pulpotomy medicaments (FC: formocresol, FS: ferric sulfate, CH: calcium hydroxide, and MTA: mineral trioxide aggregate) in this study. The criteria for tooth selection for inclusion were no clinical and radiographic evidence of pulp pathology. During 30 months of follow-up at 6-month intervals, clinical and radiographic success and failures were recorded. The differences between the groups were statistically analyzed using the Chi-square test and Kaplan-Meier analysis. Results: At 30 months, clinical success rates were 100%, 95.2%, 96.4%, and 85% in the FC, FS, MTA, and CH groups, respectively. In radiographic analysis, the MTA group had the highest (96.4%), and the CH group had the lowest success rate (85%). There were no clinical and radiographic differences between materials (P > 0.05). Conclusions: Although there were no differences between materials, only in the CH group did three teeth require extraction due to further clinical symptoms of radiographic failures during the 30-month follow-up period. None of the failed teeth in the other groups required extraction during the 30-month follow-up period.

Abstract Purpose To compare clinical success rates and reductions in intraocular pressure (IOP) and IOP-lowering medication use following suture trabeculotomy ab interno (S group) or microhook trabeculotomy (μ group). Methods This retrospective review collected data from S (n = 104, 122 eyes) and μ (n = 42, 47 eyes) groups who underwent treatment between June 1, 2016, and October 31, 2019, and had 12-month follow-up data including IOP, glaucoma medications, complications, and additional IOP-lowering procedures. The Kaplan–Meier survival analysis was used to evaluate treatment success rates defined as normal IOP (> 5 to ≤ 18 mm Hg), ≥ 20% reduction of IOP from baseline at two consecutive visits, and no further glaucoma surgery. Results Schlemm’s canal opening was longer in the S group than in the μ group (P < 0.0001). The Kaplan–Meier survival analysis of all eyes showed cumulative clinical success rates in S and µ groups were 71.1% and 61.7% (P = 0.230). The Kaplan–Meier survival analysis of eyes with preoperative IOP ≥ 21 mmHg showed cumulative clinical success rates in S and μ groups were 80.4% and 60.0% (P = 0.0192). There were no significant differences in postoperative IOP at 1, 3, and 6 months (S group, 14.9 ± 5.6, 14.6 ± 4.5, 14.6 ± 3.9 mmHg; μ group, 15.8 ± 5.9, 15.2 ± 4.4, 14.7 ± 3.7 mmHg; P = 0.364, 0.443, 0.823), but postoperative IOP was significantly lower in the S group at 12 months (S group, 14.1 ± 3.1 mmHg; μ group, 15.6 ± 4.1 mmHg; P = 0.0361). There were no significant differences in postoperative numbers of glaucoma medications at 1, 3, 6, and 12 months (S group, 1.8 ± 1.6, 1.8 ± 1.5, 2.0 ± 1.6, 1.8 ± 1.5; μ group, 2.0 ± 1.6, 2.0 ± 1.6, 2.1 ± 1.6, 2.2 ± 1.7; P = 0.699, 0.420, 0.737, 0.198). Conclusion S and µ group eyes achieved IOP reduction, but μ group eyes had lower clinical success rates among patients with high preoperative IOP at 12 months.

Abstract EASYDO ACTIVATOR (EA) is a continuously vibrational device for root canals irrigation, but its cleaning effectiveness has not been evaluated by any published reports. We were aiming to evaluate whether EA results in a greater intracanal smear layer and debris removal than conventional needle irrigation (NI) and passive ultrasonic irrigation (PUI). Twenty-seven single-rooted teeth were used. Canals were sized to R30 and irrigated with 3% sodium hypochlorite. Species were divided into three groups: Group 1: NI; Group 2: PUI; Group 3: EA. Canal walls were subjected to scanning electron microscopy. NI- and PUI-group canal cleanliness decreased from the coronal to apical direction (P < 0.05), except for EA group in the apical third. PUI removed more smear layer from the coronal and middle thirds than EA and NI (P < 0.05). PUI and EA were superior to NI regarding debris removal (P < 0.05). The smear layer and debris from the coronal and middle thirds were effectively removed with EA and PUI. More effective removal occurred from the apical third for EA compared with PUI (P < 0.05). Both methods removed smear layer and debris better than NI, providing a theoretical basis for the clinical application of EA.

Background and aim: Comparison of different irrigation and agitation methods for the removal of two types of calcium hydroxide medicaments from the root canal walls.Methods: Fifty extracted single rooted teeth were selected for this study. After decoronation, the root canals of these teeth were prepared to the size F3 (30 no.) using rotary ProTaper file system. These samples were randomly divided into four groups. Group 1 (n=20) were filled completely with water based calcium hydroxide (CH), Group 2 (n=20) were filled with oil based CH using lentulo spiral, Group 3 (n=5) - the positive control group received the CH as intracanal medication, but no subsequent removal, Group 4 (n=5) - the negative control did not receive CH placement. Further on, Group 1 and Group 2 were divided into four sub-groups (n=5). In sub-group A we performed conventional syringe irrigation with side-vented needle sub-group B) manual dynamic agitation, sub-group C sonic agitation using endoactivator, sub-group D passive ultrasonic irrigation (PUI). Roots were split longitudinally into mesial and distal halves. Digital images of the root canal walls were acquired by a Dental Operating Microscope (DOM) and assessed by using a scoring criteria at different thirds (coronal, middle and apical) of the root canal as follows: score 1, score 2, score 3, and score 4. Data were analyzed applying one-way analysis of variance (ANOVA) and Tukey’s multiple comparison tests at a 95% confidence interval (P < 0.05).Results: Statistically significant differences were not found between the experimental groups and the negative group in any one third of the root canal (P>0.05). However, a difference did exist between the experimental groups and the positive control group (P<0.05). None of the experimental groups totally removed CH substances from root canal walls.Conclusion: Among all experimental groups, removal of CH was best achieved by sonic agitation using endoactivator followed by passive ultrasonic irrigation (PUI), manual dynamic agitation and conventional syringe irrigation with side-vented needle.

Background. Tuberculosis (TB) is a public health concern, especially in resource-constrained countries like Cameroon. TB drug resistance is a major obstacle to control and prevent. Design. Data from 2014 to 2016 on the outcome of anti-TB treatment in the Littoral Region were reviewed manually and analysed using the meta-analysis concept. The treatment success rates (TSR) were the primary outcome used for this study. The heterogeneity statistics (I2) was computed to orientate the choice of the best statistical model (binary fixed effect or random) to compute pooled value of TSR. Results. Using an intention-to-treat analysis, the pooled proportions of HIV-uninfected TB patients successfully cured from TB were low and slightly decreased by 1% between 2014 and 2016. Regarding HIV-infected TB patients, pooled values of TSR were lower than those of their HIV-negative counterparts with values ranging from 71% (95% CI: 63%-83%; I2=71.16%) in 2014 to 68% (95% CI: 58%-79%; I2=70.97%) in 2016. In addition, no heterogeneity was found in three years (I2=0.0%; P value = 1). These cure rates were strongly and negatively correlated with the rates of patients lost to follow-up regardless of the year. In HIV-infected patients, the pooled values of ITT analysis-based treatment success rates were 73% (χ2=13.92, P value = 0.0002), 71% (χ2=7.26, P value = 0.007), and 68% (χ2=8.02, P value = 0.004), respectively. The coverage rates with cotrimoxazole (CTX) gradually increased over year ranging from 78.90% in 2014 to 94.17% in 2016, similar to the coverage rate for ARV therapy that was 60.06% in 2014 against 90% in 2016. A positive and statistically significant correlation was found between the success of the anti-TB therapy in HIV-infected patients and coverage rates with CTX and ARV. Conclusion. An improvement in the reduction of percentage of lost to follow-up and coverage with CTX and ARV therapy could greatly increase chances to efficiently control TB in Cameroon.

Objective To review clinical outcomes of varicose vein patients treated with cyanoacrylate embolization and radiofrequency ablation at our institution. Methods A retrospective review of patients who underwent cyanoacrylate embolization and radiofrequency ablation during a three-year period. Patient records were reviewed to assess demographics, location and severity of disease, treatment details and outcome at short- and mid-term follow-ups. Outcome parameters included treatment success and complications. Results Between January 2014 and December 2016, 335 patients with 476 veins were treated with either cyanoacrylate embolization (n = 148) or radiofrequency ablation (n = 328) at the Vancouver General Hospital Vascular Surgery Vein Clinic. The average age of patients were 57 ± 1 years with the majority being female (78%) and an average BMI of 24.8 ± 0.5. CEAP classes were 2 (49%), 3 (26%), 4a (22%) and >4b (3%). Of the veins treated with cyanoacrylate embolization, the vein types were as follows: 76% were great saphenous vein, 16% were small saphenous vein, 5% were anterior accessory great saphenous vein and 1.4% were perforator veins. The vein types for radiofrequency ablation were 88%, 9%, 3% and 0%, respectively. The average amount of cyanoacrylate embolization delivered for great saphenous vein treatment was 1.8 ± 0.1 ml with a treatment length of 43 ± 1 cm. Subgroup comparison was done for great saphenous vein segments. Treatment success was 100% in cyanoacrylate embolization and 99% in radiofrequency ablation. Superficial phlebitis was the most common complication noted at mid-term follow-up in 5% of cyanoacrylate embolization and 16% of radiofrequency ablation treatments (P < 0.05). One patient in each group had asymptomatic proximal thrombus extension treated with anticoagulation for 2–3 weeks. Three superficial infections from glue clumps were noted in the cyanoacrylate embolization group requiring excision and drainage. Five patients in the radiofrequency ablation group had persistent numbness and one wound complications at the access site. Conclusion Cyanoacrylate embolization offers equivalent success rates with lower mid-term complication rates as radiofrequency ablation.

Abstract Objective To study the incidence of side effects from muscle tissue during therapy with atorvastatin at various doses in patients with acute ST-segment elevation myocardial infarction (STEMI) during 48 weeks of follow-up. Methods The study included 115 STEMI patients aged 30 to 65 years (mean age 51.7±9.5 years). Patients were randomized to atorvastatin treatment groups. Group 1 included 59 people who took atorvastatin 80 mg / day; group 2 - 56 patients who received moderate doses of atorvastatin. The compared persons were matched by age, sex, and anthropometric data. Initially on the 7–9th days, after 24 and 48 weeks of follow-up, the CPK-MB serum level was analyzed. Muscle damage was assessed after 5–6, 24, 48 weeks of follow-up according to the development of the following symptoms: pain, fatigue, muscle weakness, decreased physical activity - on a 10-point scale. Results The CPK-MB level in the 1st group initialy was 701.5 [95% CI 391; 1012] U / L, after 24 weeks - 162.8 [95% CI 130.2; 195.4] U / L (p&lt;0.001), after 48 weeks - 205.6 [95% CI 134.8; 276.4] U / L (p&lt;0.001). In group 2, the dynamics of CPK-MB: on days 7–9 - 522.7 [95% CI 115.8; 755.1 U / L, after 24 weeks - 141.4 [95% CI 122.6; 160.3] U / L (p=0.0004), after 48 weeks - 150.5 [95% CI 123.9; 177.1] U / L (p=0.0003). A detailed analysis in four patients of the 1st group revealed an increase in CPK-MB &gt;4 upper limit of normal (ULN) after 48 weeks of follow-up (6.8%). Moreover, symptoms of muscle damage against the background of pathological CPK-MB values were observed only in two people (3.4%). In patients of the 2nd group after 24–48 weeks of therapy with atorvastatin, there was no increase in CPK-MB &gt;4 ULN. In addition, there were no cases of drug withdrawal in any of the groups due to an increase in CPK-MB&gt;10 ULN. Clinical symptoms of muscle damage after 5–6th, 24th and/or 48th weeks of follow-up were diagnosed in the 1st group in 41 patients (69.5%), in the 2nd group - in 31 people (55%) (p=0.11). Conclusion In STEMI patients on the background of 48-week therapy with atorvastatin, no serious adverse effects on the muscle tissue were revealed, which testifies in favor of the safety of high-dose statin therapy. The incidence of myalgia did not depend on the dose of the drug. FUNDunding Acknowledgement Type of funding sources: None.
