Database analysis of children and adolescents with Bipolar Disorder consuming a micronutrient formula

<p>Abstract</p> <p>Background</p> <p>Eleven previous reports have shown potential benefit of a 36-ingredient micronutrient formula (known as EMPowerplus) for the treatment of psychiatric symptoms. The current study asked whether children (7-18 years) with pediatric bipolar disorder (PBD) benefited from this same micronutrient formula; the impact of Attention-Deficit/Hyperactivity Disorder (ADHD) on their response was also evaluated.</p> <p>Methods</p> <p>Data were available from an existing database for 120 children whose parents reported a diagnosis of PBD; 79% were taking psychiatric medications that are used to treat mood disorders; 24% were also reported as ADHD. Using Last Observation Carried Forward (LOCF), data were analyzed from 3 to 6 months of micronutrient use.</p> <p>Results</p> <p>At LOCF, mean symptom severity of bipolar symptoms was 46% lower than baseline (effect size (ES) = 0.78) (<it>p </it>< 0.001). In terms of responder status, 46% experienced >50% improvement at LOCF, with 38% still taking psychiatric medication (52% drop from baseline) but at much lower levels (74% reduction in number of medications being used from baseline). The results were similar for those with both ADHD and PBD: a 43% decline in PBD symptoms (ES = 0.72) and 40% in ADHD symptoms (ES = 0.62). An alternative sample of children with just ADHD symptoms (n = 41) showed a 47% reduction in symptoms from baseline to LOCF (ES = 1.04). The duration of reductions in symptom severity suggests that benefits were not attributable to placebo/expectancy effects. Similar findings were found for younger and older children and for both sexes.</p> <p>Conclusions</p> <p>The data are limited by the open label nature of the study, the lack of a control group, and the inherent self-selection bias. While these data cannot establish efficacy, the results are consistent with a growing body of research suggesting that micronutrients appear to have therapeutic benefit for children with PBD with or without ADHD in the absence of significant side effects and may allow for a reduction in psychiatric medications while improving symptoms. The consistent reporting of positive changes across multiple sites and countries are substantial enough to warrant a call for randomized clinical trials using micronutrients.</p

Clinical, genetic and microbiological findings in a Brazilian family with aggressive periodontitis

Background, aim: Aggressive periodontitis comprises a group of rapidly progressive forms of periodontitis. Besides bacteria, a high level of subject susceptibility must be involved in the expression of disease. In the present study, we report the clinical, microbiological and genetic profile of a 14-individual family with aggressive periodontitis. Method: PCR was utilized to detect pathogenic bacteria of affected sites. DNA was obtained from epithelial cells through a mouthwash with 3% glucose and scrapping of the oral mucosa. RFLP-PCR was used to analyze cytokine genetic polymorphisms. Results: Localized aggressive periodontitis was diagnosed for an 18-year-old systemically healthy non-smoking proband, with siblings displaying aggressive periodontitis. Bacteroides forsythus and Treponema denticola were the most frequent pathogens. The proband presented Actinobacillus actinomycetemcomitans and detectable levels of Porphyromonas gingivalis, Bacteroides forsythus and Treponema denticola. Allele 2 of IL-1alpha (-889) polymorphism was found in all individuals as well as allele 1 of the IL-1beta (+3953) gene. Alleles 1 and 2 (50 each) of IL-1beta (-511), allele 1 of TNF-alpha (-308) and allele 2 (in homo or heterozygosity) of IL-RN (intron 2) gene were present. Conclusion: The results show that the present microbiological and genetic parameters were not relevant for the prediction of periodontitis susceptibility in this family.29323323

The influence of nicotine on the bone loss rate in ligature-induced periodontitis. A histometric study in rats

Background: The present study investigated the possible influence of nicotine on the bone loss rate in the furcation region due to ligature-induced periodontitis in rats. Methods: Twenty adult male Wistar rats were included. After anesthesia, the tooth was randomly assigned to receive the cotton ligature in the sulcular area, while the contralateral tooth was left unligated. The animals were randomly assigned to one of the following treatments, including daily intraperitoneal injections: group A, 2 mul/g body weight of saline solution; group B, 2 mul/g body weight of a nicotine solution with 0.13 mul of nicotine/ml of saline solution; group C, 2 mul/g body weight of a nicotine solution with 0.19 mul of nicotine/ml of saline solution; and group D, 2 mul/g body weight of a nicotine solution with 0.26 mul of nicotine/ml of saline solution. Thirty days later, the animals were sacrificed and the specimens routinely processed for serial decalcified sections. Results: Intergroup analysis revealed greater bone loss in the ligated teeth of group B (1.01 +/- 0.61 mm(2)), group C (1.14 +/- 0.72 mm(2)), and group D (1.36 +/- 0.60 mm(2)) when compared with group A (0.64 +/- 0.62 mm(2)) (P <0.01). However, no statistically significant differences in bone loss were found among groups B, C, and D. In addition, no bone loss was observed for unligated teeth (P >0.01). Conclusions: Within the limits of the present study, nicotine enhanced the effects of the local components of periodontal disease in a non-dose-dependent way; nevertheless, the administration of nicotine did not produce periodontal bone loss by itself.7191460146

Histometric evaluation of the effect of nicotine administration on periodontal breakdown: an in vivo study

The present study investigated the effect of nicotine administration on periodontal breakdown resulting from ligature-induced periodontitis in rats. Twenty adult male Wistar rats were used. After anesthesia, a mandibular first molar was randomly assigned to receive a cotton ligature in the sulcular area while the contralateral tooth was left unligated. The animals were randomly assigned to one of the following treatments, of daily intraperitoneal injections: A - saline solution, B - 0.37 mg of nicotine/kg, C - 0.57 mg of nicotine/kg and D - 0.73 mg of nicotine/kg. Thirty days later, the animals were sacrificed and the specimens routinely processed for serial decalcified sections. Statistical analysis (ANOVA) revealed greater bone loss (p <0.05) in the ligated teeth of animals which received nicotine (groups B/C/D) thin in the ligated teeth of animals which received saline solution (group A). In addition, a dose-dependent response was observed among the nicotine groups. A negative effect of nicotine was observed in the unligated teeth of the experimental groups (p < 0.05). Therefore, daily administration of nicotine enhanced, in a dose-dependent manner, the effects of local factors in producing periodontal breakdown. Furthermore, the nicotine seemed to have a direct deleterious effect on the periodontal tissues.36636136
