Primary subcutaneous cyst hydatic disease in proximal thigh: an unusual localisation: a case report

BACKGROUND: Musculoskeletal hydatidosis is very rare and represents 1% – 5.4% of all cases of echinococcosis. On clinical basis, infection mimics a soft-tissue tumor, and the preoperative radiological diagnosis is very important to avoid biopsy. CASE PRESENTATION: We report an unusual case of primary subcutaneous hydatidosis in proximity to vastus lateralis muscle. It was diagnosed according to the computed tomography appearance, clinical and pathological findings. A 43 year old female patient was admitted with a history of pain at proximal thigh for the last 30 days. On physical examination, a mass which was 4 × 5 cm in diameter, painful and erythamatous, was palpated over greater trochanter. Sedimentation rate was 40 mm in the first hour. CT (Computed Tomography) scan demonstrated, a soft tissue mass with central cystic component in the subcutaneous tissue near vastus lateralis muscle. Histopathological examination of the specimen revealed a pericystic structure, which consisted of connective tissue and scattered hyaline cells showing a necrotic basophilic structure that resembled a cuticular membrane. Treatment with high dose albendazole was conducted for 4 weeks. CONCLUSIONS: This case illustrates that echinococcal disease should be considered in the differential diagnosis of every cystic mass in every anatomic location, especially when they occur in areas where the disease is endemic

Antibacterial characteristics of glass ionomer cements containing antibacterial agents: an in vitro study

Kurt, Ayca/0000-0003-4762-7495WOS: 000526339200001PubMed: 32297158Purpose the objective of this study was to evaluate the antibacterial activity (ABA), Vickers microhardness numbers (VHN) and cumulative fluoride-releasing (CFR) patterns of conventional glass ionomer cement (GIC) containing AB agents. Methods Chlorhexidine (CHX), Cetrimide (CT) and Cetylpyridinum Chloride (CPC) were added to the powder and Benzalkonium Chloride (BC) was added to liquid of GIC in concentrations of 1% and served as the experimental group (EG). Antibacterial-free GIC was used a control group (CG). Results Compared to the CG, a statistically significantly higher level of ABA was detected at the 1st and 7th day against Streptococcus mutans (SM) and on all days against Lactobacillus casei (LC). the CG had statistically significantly high microhardness values in all time periods compared to the EG. With regard to fluoride ion release, there was no statistical difference between CG and EG at all times. A statistically significant increase was observed in both CG and EG during the 1st day to the 30th day. Conclusion the results of this in vitro investigation demonstrated that AB agents added to the GIC can exhibit AB effects against SM and LC without seriously damaging the physical and chemical properties of the material

Short-term antibacterial activity and compressive strength of biodentine containing chlorhexidine/cetirimide mixtures

PubMedID: 30729947Background and Purpose: Aim is to evaluate the antibacterial activity and physical properties of Biodentine containing chlorhexidine (CHX)/cetrimide (CT) mixtures at 24 h. Materials and Methods: Powder formulations of CHX (2.5%) and CT (2.5%) were added to the powder of Biodentine and served as experimental groups (EXP). Antibacterial free groups were designed as control (CNT). The antibacterial acitivity (AB) (n = 5; for each) of disc-shaped specimens against Streptococcus mutans and Lactobacillius casei and compressive strength (CS) (n = 10; for each) tests used both for groups after 24 h after polymerization. Statistical Analysis Used: Normality of data were tested with the Shapiro-Wilk test. Significant differences were analyzed with the Mann-Whintey U test for both the methods (agar disk diffusion and compressive strength) at a significance level of P 0.05). Conclusion: Since the incorporation of 5% CHX/CT to the Biodentine exhibited acceptable antibacterial activity without hampering compressive strength values at 24 h, this combination could be a promising alternative for eliminating the residual bacteria for indirect pulp-capping therapies. © 2019 Nigerian Journal of Clinical Practice

Storing tooth segments for optimal esthetics

Objective: A fractured whole crown segment can be reattached to its remnant; crowns from extracted teeth may be used as pontics in splinting techniques. We aimed to evaluate the effect of different storage solutions on tooth segment optical properties after different durations. Study design: Sixty central incisor crowns were divided into 6 groups (n = 10); Group 1 was kept dry; Groups 2, 3, 4, 5, and 6 were placed in an isotonic solution, water, milk, saliva, and casein-phosphopeptide–amorphous-calcium-phosphate (CPP–ACP), respectively, for 30 min, 12 h, 1 day, 1 week, and 3 weeks. Color values were measured using a colorimeter. Data were analyzed with Kruskal–Wallis tests, Mann–Whitney U-tests, and Friedman Wilcoxon tests with Bonferroni stepwise corrections (p 0.01). Comparing ΔE* values, Group 6 was significantly different from the other groups for all durations (p < 0.01), except Group 4. Conclusions: A CPP–ACP complex solution seems a good choice for tooth fragment storage. Milk and saliva solutions may cause perceptible color changes if tooth fragments are stored for 3 weeks before use
