To evaluate the implant and prosthetic of two implants with different surfaces and neck design. Enrolled patients received bone level, 12° conical connection implants (Nobel Parallel, Nobel Biocare; NOBEL group) with anodized surface (TiUnite) and roughness of 1.35 μm, or transmucosal implant system (Prama, Sweden and Martina; PRAMA group) with convergent collar, ZIrTi surface, and roughness 1.4-1.7 μm. Both implants were made of pure grade IV titanium, with similar diameter and length, chosen according to the dentistry department availability and patient\'s request. After early prosthesis delivery, patients were filled for at least one year. Outcome measures were: implant and prosthetic survival and success rates, physiological marginal bone remodeling, periodontal parameters and pink esthetic score (PES). Results: Fifteen patients were allocated and treated in each group. At the one-year follow-up, three patients dropped out, one in the NOBEL group and two in the PRAMA group. During the entire time of investigation, all implants survived and the prostheses were successful. No statistically significant differences were found in term of marginal bone loss, periodontal parameters, and aesthetics (p > 0.05). Conclusion: With the limitations of the present study, both implant systems showed successful clinical results. Finally, many other clinical and surgical variables may influenced marginal bone levels, implant survival, and periodontal parameters. More homogenous clinical trials with larger samples are needed to confirm these preliminary conclusions.

To study oxidative stress in systemic lupus erythematosus (SLE) by estimating serum oxidised LDL (OxLDL), 8-hydroxy-2\'-deoxyguanosine (8-OHdG), malondialdehyde (MDA), and total anti-oxidant status and to correlate with SLE disease activity and disease damage. Eighty SLE patients satisfying the Systemic Lupus International Collaborating Clinics/American College of Rheumatology (SLICC/ACR) 2012 criteria and 80 healthy controls were studied. Exclusion criteria were infections, renal insufficiency, other connective tissue diseases, drug-induced lupus, smoking, alcohol consumption. Disease activity was measured by SLE disease activity index-2 K (SLEDAI), disease damage was quantified by SLICC-Damage Index (SDI). Sera was tested for OxLDL, 8-OHdG, and total antioxidant status (TAS) by double-antibody sandwich ELISA; MDA measured by Colorimetric assay. Oxidative stress markers were compared between group1- controls, group 2-mildly active SLE (SLEDAI ≤ 5), group 3- moderate to highly active SLE (SLEDAI ≥ 6). SLE patients had significantly higher MDA, 8-OHdG and lower TAS when compared to healthy controls, while OxLDL was similar in the three groups. MDA, 8-OHdG were significantly higher, TAS lower in group 3 compared to group 2. MDA had positive correlation with SLEDAI, TAS negatively correlated with SLEDAI. SLE with neuropsychiatric manifestations, vasculitis, anti-sdDNA antibodies had higher MDA, MDA/TAS ratio. SLE patients with thrombocytopenia, and vasculitis had higher OxLDL. Only OxLDL was significantly higher in those patients who have SDI > 1. SLE patients have increased oxidative stress measured by increases in MDA, 8-OHdG, and lower total antioxidant status that was associated with disease activity and some disease manifestations. However only OxLDL was associated with damage.

BACKGROUND: Hypothyroidism is one of the most common metabolic disorders associated with dyslipidemia which poses a higher risk of Coronary Artery Disease (CAD) in such patients. Biochemical markers which can pick up the risk promptly are becoming imperative now-a-days and thus the assessment beyond the conventional lipid profile is the need of the hour.
OBJECTIVE: To assess the association of non-conventional lipid parameters like small dense Low Density Lipoprotein (sd LDL), oxidized Low Density Lipoprotein (ox LDL), Apolipoprotein A (Apo A1), Apolipoprotein B (Apo B) and Lipoprotein (a) {Lp(a)} in hypothyroid patients and compare their values with the conventional lipid parameters such as Total Cholesterol (TC), Triglyceride (TG), Low-Density Lipoprotein Cholesterol (LDL-C) and High-Density Lipoprotein Cholesterol (HDL-C).
METHODS: One hundred and thirty clinically proven patients of hypothyroidism aged 20-60 years and equal number of age and gender matched healthy individuals were included in this case control study. Serum sd LDL, ox LDL, Apo A1, Apo B, Lp (a), lipid profile, Thyroid Stimulating Hormone (TSH), Free Triiodothyronine (FT3) and Free Tetraiodothyronine (FT4) levels were measured in both the groups. The data was recorded and analysed on SPSS system. The results of cases and controls were compared by student t-test and one-way ANOVA. All the parameters were correlated with TSH by Pearson\'s correlation.
RESULTS: We found significantly high levels of sd LDL, ox LDL, Apo B, Lp (a), TC, TG, LDL-C in cases as compared to the controls. Ox LDL has shown maximum correlation with serum TSH (p<0.0001, r=0.801) followed by sd LDL (p<0.0001, r=0.792), Apo B (p<0.001, r=0.783) and LDL-C (p<0.001, r=0.741). Moreover, ox LDL and sd LDL were found to be increased in normolipidemic hypothyroid patients thereby giving a strong supportive evidence that estimation of these parameters can become fundamental in prompt identification of the high risk patients of CAD in hypothyroid population.
CONCLUSIONS: Non-conventional lipid parameters appear to be better markers for the assessment of cardiovascular risk in hypothyroidism and might help in the designing of the effective treatment protocols and areas of intervention by the clinicians as well as researchers.
