Hormonal and Psychogenic Risk Factors for Erectile Dysfunction in Men with HTLV-1

IntroductionErectile dysfunction (ED) is associated with neurological damage due to human T-lymphotropic virus 1 (HTLV-1) infection, but hormonal and psychogenic factors also cause ED.AimTo evaluate the association of psychogenic and hormonal factors with ED in men infected with HTLV-1.MethodsIn this cross-sectional study, we compared total testosterone, follicle stimulating hormone, luteinizing hormone, prolactin, anxiety symptoms, depressive symptoms, and neurologic manifestations in HTLV-1-infected men with or without ED. The International Index of Erectile Function was used to determine the degree of ED. Participants were grouped according to Osame’s Motor Disability Scale and the Expanded Disability Status Scale: HTLV-1-associated myelopathy or tropical spastic paraparesis (HAM/TSP), probable HAM/TSP, or HTLV-1 carrier. Chi-square and Fisher’s exact tests were used to compare the groups, and regression analyses were used to show predictors of ED.Main Outcome MeasureSexual hormonal levels, psychogenic factors, and neurologic disabilities were found to be associated with ED.ResultsED was associated with age older than 60 years (P < .001), degree of neurologic involvement (P < .001), depression (P = .009), and anxiety (P = .008). In the multivariate analyses, only age and degree of neurological injury remained as risk factors for ED.Clinical ImplicationsNeurological manifestations are a stronger predictor of ED than hormonal and psychogenic factors in HTLV-1-infected men.Strengths & LimitationsThe statistical power of the study was limited due to the low number of participants, but neurologic manifestations were clearly associated with ED. There was no strong association between hormonal and psychogenic factors and ED.ConclusionHormonal and psychogenic factors did not show a strong association with ED in individuals with HTLV-1, but neurological manifestations were strongly associated with ED in these individuals.de Oliveira CJV, Neto, JAC, Andrade RCP, et al.

Effect of enamel matrix proteins on the treatment of intrabony defects: a split-mouth randomized controlled trial study

The objective of this split-mouth, double-blind, randomized controlled trial was to compare the clinical effect of treatment of 2- or 3-wall intrabony defects with open flap debridement (OFD) combined or not with enamel matrix proteins (EMP). Thirteen volunteers were selected with one pair of or more intrabony defects and probing pocket depth (PPD) > or = 5 mm. All individuals received instructions regarding oral hygiene and were submitted to scaling and root planing. Each participant received the two treatment modalities: test sites were treated with OFD and EMP, and control sites received only OFD. After 6 months, a significant reduction was observed in PPD for the EMP group (from 6.42 +/- 1.08 mm to 2.67 +/- 1.15 mm) and for the OFD group (from 6.08 +/- 1.00 mm to 2.00 +/- 0.95 mm) (p < 0.0001), but with no significant difference between groups (p = 0.13). A significant gain in relative attachment level (RAL) was observed in both groups (EMP: from 13.42 +/- 1.88 mm to 10.75 +/- 2.26 mm, p < 0.001; OFD: from 12.42 +/- 1.98 mm to 10.58 +/- 2.23 mm, p = 0.013), but with no significant difference between groups (p = 0.85). Gingival recession (GR) was higher in the EMP group (from 1.08 +/- 1.50 mm to 2.33 +/- 1.43 mm; p = 0.0009) than in the OFD group (from 0.66 +/- 1.15 mm to 1.16 +/- 1.33 mm; p = 0.16), but this difference was not significant (p = 0.06). In conclusion, the results showed that OFD combined with EMP was not able to improve treatment of intrabony defects compared to OFD alone.     

Effect of two routes of administration of dexamethasone on pain, edema, and trismus in impacted lower third molar surgery

Purpose

The aim of the present study was to compare pain, edema, and trismus in the postoperative period following third molar surgery using 8?mg of dexamethasone administered either orally or through local injection.

Methods

A prospective, controlled, randomized trial was carried out involving 60 lower third molar surgeries in 67 patients between October 2008 and June 2009. The sample was randomly divided into three groups: group A (local injection), group B (tablets), and group C (control). In all cases, either ostectomy or crown sectioning was employed. On the second and seventh day following surgery, linear edema was determined using facial landmarks, and maximal mouth opening measurements were performed. Postoperative pain was recorded using a visual analog scale.

Results

Patient age ranged from 14 to 37?years (mean, 21.0?years). With regard to pain, edema, and trismus, the two administration routes tested (local injection and tablets) demonstrated similar efficacy, and both methods achieved better results in comparison to the control group.

Conclusion

Both the oral administration and local injection of dexamethasone proved effective in reducing pain, edema, and trismus compared to control group following lower third molar surgeries, achieving similar results.
