This prospective study sought to evaluate the healing quality of implanted ultraporous β-tricalcium phosphate sown with expanded autologous mesenchymal stromal cells (MSCs) into femoral defects during revision hip arthroplasty. A total of 37 osseous defects in 37 patients were treated and evaluated concerning bone regeneration. Nineteen subjects received β-tricalcium phosphate graft material serving as a carrier of expanded autologous MSCs (the trial group A), nine subjects received β-tricalcium phosphate graft material only (the study group B) and nine subjects received cancellous allografts only (the control group C). Clinical and radiographic evaluations were scheduled at 6 weeks, 3, 6, and 12 months post-operatively, and performed at the most recent visit as well. All observed complications were recorded during follow-up to assess the use of an ultraporous β-tricalcium phosphate synthetic graft material combined with expanded MSCs in bone defect repair. The resulting data from participants with accomplished follow-up were processed and statistically evaluated with a Freeman–Halton modification of the Fischer’s exact test, a P < 0.05 value was considered to be significant. Whereas no significant difference was observed between the trial group A with β-tricalcium phosphate synthetic graft material serving as a carrier of expanded autologous MSCs and control group C with cancellous impaction allografting in terms of the bone defect healing, significant differences were documented between the study group B with β-tricalcium phosphate graft material only and control group C. Regarding adverse effects, six serious events were recorded during the clinical trial with no causal relationship to the cell product. β-tricalcium phosphate synthetic graft material serving as a carrier of expanded autologous MSCs appears safe and promotes the healing of bone defects in a jeopardized and/or impaired microenvironment. This clinical trial was registered at the EU Clinical Trials Register before patient recruitment (Registration number: EudraCT number 2012-005599-33; Date of registration: 2013-02-04).

Objective: To evaluate the effectiveness of placing a resorbable collagen barrier in impeding the extrusion of obturation material in primary molars undergoing resorption. Study design: All the 94 canals in 47 mandibular molars were allocated to 2 groups- Group ‘A’- 47 canals with collagen barrier (Test group) and Group ‘B’- 47 canals without collagen barrier (Control group) based on randomization protocol. Pulpectomy was performed and obturation of both test and control canals were radiographically assessed. Pearson’s chi – square test was applied to analyze the results. The significance level was predetermined at p &lt; 0.05. Results: Among the test group, 93.6% of the canals showed no extrusion while, 6.4% showed visible extrusion of the material outside the apex. In the control group, 83% showed no extrusion whereas 17% of the canals showed visible extrusion outside the apex. But no significant difference was noted (p&gt;0.05). Conclusion: The placement of resorbable collagen barrier in the apical third of the canal prevented the extrusion of obturating material beyond the apex in resorbing primary molars.

Augmentation rhinoplasty is one of the most common plastic surgery procedures performed in Asia. Most Asian patients desire not only a natural-looking nose but also a nose with natural feel. Achieving such rhinoplasty outcomes with grafts has been a challenge for surgeons due to rigidity of grafting material. We propose a novel technique to address this limitation. A total of 200 healthy adult patients aged from 18 to 25 years were randomly chosen and classified into 5 groups: A, B, C, D, and control. Each group included 40 patients. The patients assigned to conventional grafting underwent rhinoplasty with L-shaped silicone prosthesis (group A) or expanded polytetrafluoroethylene (e-PTFE; group B), using traditional carving methods. The patients assigned to dynamic rhinoplasty underwent silicone (group C) or e-PTFE grafts (group D) using the modified double “V” method, which involves removing bilateral wedges from the graft to decrease rigidity. Patients in control group do not undergo the surgery. A 3-dimensional raster surface scanner was used to capture the images of the patients accurately and nasal mobility was measured. Subjective evaluations were carried out by a series of questionnaires asked to the patients. The angle α of nasal mobility was significantly lower in conventional grafting (23.09 [5.34] mm for silicone and 17.88 [4.96] mm for e-PTFE) versus the “V” carving (30.53 [3.76] mm for silicone and 23.77 [4.53] mm for e-PTFE; P < .05). The double “V” carving method is a simple, effective, and practical method for improving dynamic nasal outcomes in patient undergoing augmentation rhinoplasty.

Objective: To study the effect and safety of Fenofibrate in uncomplicated hyperbilirubinemia in newborn with 6-month follow-up. Materials and Methods: This is a randomized controlled clinical trial conducted in 60 normal term neonates admitted for uncomplicated hyperbilirubinemia in NICU at Sir T G Hospital, Bhavnagar from January 2012 to December 2012. The data included: age, sex, total serum bilirubin (TSB), weight and duration of phototherapy. All neonates enrolled in the study received phototherapy. They were divided in two groups of 30 each: control group A and group B receiving Fenofibrate (100 mg/kg single dose). There was statistically insignificant difference between the parameters of age, sex, weight and TSB between the two groups at hospitalization. Data was analyzed by using appropriate statistical methods. Results: Mean values for total serum bilirubin in Fenofibrate group B at 24 and 48 hours after admission were significantly lower than those for control group A (p<0.0001,  p=0.0001). There was no significant difference in fall of TSB between 24 and 48 hours. The mean duration of phototherapy in Fenofibrate group (44.8h: 24-72h) was significantly shorter than that in control group (55.2 h: 24‐96 h) (P=0.02). There were no side effects of the drug observed during the study and during 6 months follow up period. Conclusion: Fenofibrate as a single 100 mg/kg dose in healthy full term neonates, is effective and a safe drug (till six-month follow-up) for neonatal hyperbilirubinemia, that can decrease the time needed for phototherapy and hence hospitalization. Effect of a single dose seems to wane after 24 hours.

To observe the clinical effect of nano-carbon adsorption of 5-fluorouracil (5-FU) on Breast cancer lymph node metastasis in New Zealand rabbits. A breast cancer animal model was established by local injection of a VX2 tumor tissue suspension in thirty New Zealand rabbits. An observation group, control group A, and control group B were established using a random number table, with ten rabbits in each group. Once tumors with a diameter ≥5 mm were identified in the lymph nodes, the animals received the intervention. The observation group had nano-carbon-5-FU suspension subcutaneously injected, control group A had 5-FU subcutaneously injected through the ear margin, and control group B had 5-FU subcutaneously injected; all received a drug dose of 30 mg · kg–1. Half of the animals in the three groups were killed following treatment for thirty minutes, while the rest of the animals were killed following treatment for seven days. Tumors and lymphatic metastases were removed. Tumor and lymphatic metastasis volume were compared. H&E stained sections were used to determine the ND of tumor cells. A dTUP TUNEL assay using Terminal Deoxynucleotidyl Transferase (TdT) was used to assess tumor cell apoptosis. The expression level of casapase-3 mRNA in tumors and lymphoid tissues was determined using RT-PCR. After treatment for 30 mins, the observation group exhibited a significantly higher 5-FU concentration in lymph node metastases, and significantly lower 5-FU concentrations in plasma and tumors. Nano-carbon can increase the 5-FU concentration in tumor tissue, as well as enhance the clinical effect of drugs on lymph node metastases.

AbstractAssociation of SOD2 V16A single-nucleotide polymorphism (rs4880) with drug hepatotoxicity were reported but relationships with amiodarone prescriptions remained unexplored. Research was an exploratory, controlled prospective clinical trial. Patients hospitalized and treated in Clinical Center in Kragujevac, Serbia (in year 2017) were divided into experimental (using amiodarone, having liver injury, n=29, 19 males, the mean age 66.8±10.4 years), control A (neither amiodarone use nor hepatotoxicity, n=29, 19, 66.1±10.3) and control B group (using amiodarone, not having hepatotoxicity, n=29, 19, 66.8±9.8). From blood samples, among other routine biochemistry, genotyping for SOD2 polymorphism Val16Ala was conducted using real-time PCR method with TaqMan® Genotyping Master Mix and TaqMan® DME Genotyping Assay for rs4880. Patients taking amiodarone and having liver injury were mostly carriers of Val/Val (TT) genotype (13 of 24 patients, 54.2%) while Val/Ala (TC) and Ala/Ala (CC) genotypes prevailed in control group A (19 of 40, 47.5%) and control group B (9 of 23, 39.1%), respectively (2=10.409, p=0.034). Frequency of Val (T) and Ala (C) alleles were 0.51 and 0.49, respectively in the whole study sample (Hardy Weinberg equilibrium, 2=0.56, p=0.454). Carriers of TT genotype had significantly higher ALT (437.0±1158.0 vs 81.9131.5 U/L), total bilirubin (28.320.5 vs 15.313.0 mol/L) and total bile acid concentrations (10.910.2 vs 6.45.3 mol/L) compared to carriers of TC genotype (U=2.331, p=0.020, U=3.204, p=0.001 and U=2.172, p=0.030, respectively). Higher incidence of 47T allele of SOD2 was inpatients with amiodarone-associated liver injury as compared to patients on amiodarone not experiencing hepatotoxic effects.

Background: There are few biomarkers that can be easily accessed in clinical settings and may reflect refractory Th2-eosinophlic inflammation and remodeling of the asthmatic airways. Serum periostin may be one such biomarker to aid our understanding of the patho-bio-physiology of asthma and exercise induced asthma. The aim of the study is to explore the relationship between serum periostin level and exercise induced bronchoconstriction in asthmatic children. Materials and Methods: This cross-sectional study was carried out on (90) children both sexes aged from 6 to 15 years including, (60) children with bronchial asthma and (30) children were enrolled as control group in the period from January 2018 to January 2019. Patients were randomly classified into two groups: I) Patient group: divided into 2 groups according to standardized treadmill exercise challenge test: Group A: (30) asthmatic children with positive test. Group B: (30) asthmatic children with negative test. II-Control group: (30) children apparently healthy with no personal or family history of asthma. All children were subjected to the following Investigations: Chest x-ray, pulmonary functions tests (FEV1 & PEFR) except controls, Laboratory investigations as CBC and Serum periostin level. Results: The mean values of both the percentage of PEFR and FEV1 after exercise in group A were significantly lower than those in group B and the percentage of PEFR and FEV1 after exercise in each group were significantly lower than the percentage before exercise in the same group. The mean value of eosinophilic count in group A was significantly higher than (group B and control group) and the mean value of eosinophilic count in group B was significantly higher than control group. The mean value of serum level of periostin in group A was significantly higher than (group B and control group), however, there was no significant difference between group B and control group as regard to serum level of periostin. Chest tightness, cough and wheezes after exercise and eosinophilic count in patients with high serum periostin level were significantly higher than patients with low serum periostin level, and both PEFR and FEV1 after exercise in patients with high serum periostin level were significantly lower than patients with low serum periostin level. Also the normal serum periostin levels vary among different age groups. Conclusion: Serum periostin level can be considered as a useful biomarker for diagnosis of Exercise induced bronchospasm (EIB) in asthmatic children especially when lung function test cannot be done However, cautious is required in evaluating serum periostin levels in children because it varies with age.

The demand for synthetic graft materials in implant dentistry is rising. This systematic review aims to evaluate the survival rate of dental implants placed simultaneously with bone regeneration procedures using the material β-tricalcium phosphate, one of the most promising synthetic graft materials. The electronic search was conducted in PubMed, Scielo, and the Cochrane Central Register of Controlled Trials. There were five randomized clinical trials, one of which was a non-randomized controlled clinical trial and four of which were observational studies without a control group included. Implant survival rate and other clinical, radiographic, and histological parameters did not differ from those of implants placed simultaneously with another type of graft material, or placed in blood clots or natural alveolar ridges. Based on the available literature, β-tricalcium phosphate seems to be a promising graft material in implant dentistry. Nevertheless, more randomized clinical trials, with long follow-up periods, preoperative and postoperative CBCT, and histological analysis, are necessary to assess its long-term behavior.
