Association between psychotropic medications and presence of sleep bruxism: A systematic review.

The purpose of this study was to systematically review the literature for studies that investigated the association between use of psychotropic medications and presence of sleep bruxism (SB). Observational studies were selected in a two-phase process. Searches were performed on six electronic databases, and a grey literature search was conducted on three databases. SB diagnosis was based on questionnaires or clinical examinations; no polysomnography examinations were performed. Risk of bias was assessed using the Joanna Briggs Institute Critical Appraisal Checklist for Analytical Cross-Sectional Studies. Overall quality of evidence was evaluated according to the Grading of Recommendations Assessment, Development and Evaluation criteria. Five analytical cross-sectional studies were included, evaluating antidepressants, anticonvulsants and psychostimulants. One study was judged as low risk of bias, three as moderate risk and one high risk. Antidepressants were evaluated in adult populations only; duloxetine (Odds Ratio [OR] = 2.16; 95% Confidence Interval [95% CI] = 1.12-4.17), paroxetine (OR = 3.63; 95% CI = 2.15-6.13) and venlafaxine (OR = 2.28; 95% CI = 1.34-3.86) were positively associated with SB risk. No increased odds of SB were observed considering use of citalopram, escitalopram, fluoxetine, mirtazapine and sertraline. With regard to anticonvulsants, only barbiturates were associated with SB in children (OR = 14.70; 95% CI = 1.85-116.90), while no increased odds were observed for benzodiazepine, carbamazepine and valproate. The only psychostimulant evaluated was methylphenidate, and an association with SB was observed in adolescents (OR = 1.67; 95% CI = 1.03-2.68). Findings from this SR suggested that medications such as duloxetine, paroxetine, venlafaxine, barbiturates and methylphenidate might be associated with SB; however, overall quality of evidence was considered very low, and therefore, caution is recommended.

Risk factors for anterior traumatic dental injury in children and adolescents with autism spectrum disorders: a case-control study.

AIM: This was to assess and compare risk factors for traumatic dental injury (TDI) among children/adolescents with and without autism spectrum disorders (ASD). METHODS: The study consisted of 122 children and adolescents (98 males, 24 females), 61 with ASD (study group) and 61 without ASD (control group, CG). Dental injuries were determined according to Andreasenss classification. The cause, location and type of activity at the time of trauma were recorded from patient/carer recollection. RESULTS: Subjects with ASD presented higher percentages of TDI in routine activities (P = 0.003), falling while walking and episodes of self-harm (P = 0.007) in the individual's own residence (P = 0.036). TDI prevalence in the ASD group was higher (39.3%) than in the CG (26.2%) though not significant, (P = 0.123). Girls with ASD presented a significantly higher TDI percentage (50.0%) compared with girls from the CG (8.3%) (P = 0.024). Enamel fracture was the most frequent type of TDI for both groups (P = 0.292). The teeth most commonly affected were #11 and #21 for both groups. CONCLUSIONS: Children and adolescents with ASD exhibit different risk factors for TDI compared with those without ASD, and girls with ASD are more prone than boys.

Survival of Kidney Allograft of Donors after Circulatory Death Is Similar to Donors after Brain Death: Experience in a Regional Program.

BACKGROUND: Donors after circulatory death (DCD) are an increasingly crucial source of organs to maintain deceased donor kidney transplant activity when faced with a standstill in donors after brain death (DBD). We analyzed the influence on graft survival since the use of DCD organs was implemented in Andalusia (2010-2014). METHODS: We compared 164 kidney transplants from DCD (83 Maastricht type II and 81 type III) and 1488 DBD transplants in recipients over the age of 18, excluding combined transplants. RESULTS: DCD were more frequently men from the A blood group who were younger (48.9 ± 11 vs 55.2 ± 15 years old for DBD, P < .001). Kidneys from DCD were implanted in younger recipients (51.2 ± 11 vs 53.5 ± 13 years old for DBD, P = .03), more frequently in men from blood group A who spent less time in renal replacement therapy (39.8 vs 51.5 months), in a lower proportion of immunized recipients and re-transplant patients, and had worse HLA-DR compatibility. DCD presented a proportion of primary nonfunctional allografts and an initial need for dialysis of 8.8% and 69.6% vs 5.5% and 29.6% for DBD (P < .001). DCD allograft recipient survival was 96% and 96% at the first and third year respectively, vs 96% and 93% with a DBD graft (NS). Survival of the graft was 91% and 86% at the 1(st) and 3(rd) years, vs 90% and 86% with a DBD allograft (NS). No significant difference was found between Maastricht type II and III. DCD were related to lower graft survival versus DBD under the age of 50 (n = 445), 86% vs 92% (P = .02) in the third year, but were similar to DBD from age 50 to 59 (n = 407) and higher than DBD over age 60 (n = 636), 80% at the 3(rd) year (NS). The survival of DCD recipients was not different than DBD in those under 60 and was significantly better than DBD at or over the age of 60 (96% vs 87% in the 3(rd) year, P = .036). In the multivariable survival study (Cox, covariates of influence previously demonstrated in our region) DCD are not a significant survival prognosis factor for the recipient or the allograft. CONCLUSIONS: With the current guidelines of donor selection and allocation of organs applied in Andalusia, the survival of kidney transplants from DCD overall is similar to DBD. The graft performance tends to be better than DBD over the age of 60, the main source of donors at present.

Association between anticonvulsant drugs and teeth-grinding in children and adolescents with cerebral palsy.

The relation between teeth-grinding and the use of drugs acting on the central nervous system of cerebral palsy (CP) patients has not yet been described. The aim of this research was to evaluate the presence or absence of teeth-grinding (sleep and/or awake periods) in normal and in CP children and adolescents, as well as the association of teeth-grinding and use of anticonvulsant drugs. The sample consisted of 207 children and adolescents, divided into three groups: G1, individuals with CP who did not take anticonvulsant drugs; G2, individuals with CP administered medications on a regular basis; and CG, normal individuals. Logistic regression analyses were performed to evaluate the association of teeth-grinding with some variables. No significant statistical differences were observed regarding the presence or absence of teeth-grinding when G1 and G2 were compared. However, compared with the CG, a statistically significant difference was determined, with the CG showing fewer children presenting teeth-grinding (P < 0·001). Among those children/adolescents prescribed drug therapy, the barbiturate group showed a greater frequency of teeth-grinding. CP children and adolescents show a greater and significant presence of grinding of the teeth compared with normal individuals. Subjects taking barbiturate drugs showed greater presence of teeth-grinding, than those who were taking medications from the other groups of anticonvulsant drugs.

Frequency of temporomandibular disorder signs in individuals with cerebral palsy.

This study aimed to determine the frequency of temporomandibular disorder (TMD) signs in 68 individuals with cerebral palsy, aged between 3 and 23 years. TMD signs were evaluated according to the Research Diagnostic Criteria to assess temporomandibular joint sounds, lateral jaw deviation during opening and closing movements and limitation of maximum mouth opening (>40 mm). The frequency of TMD signs observed in the cerebral palsy group (46/68-67.6%) was higher than in the control group (17/68-25%). The clinical scenario of CP seems to make these individuals more prone to the development of TMD signs.

Frequency of parafunctional oral habits in patients with cerebral palsy.

Cerebral palsy (CP) is one of the most frequent conditions encountered in the daily practice of dentists who treat special-needs patients and it seems that parafunctional oral habits are often present in such individuals. The aim of this study was to investigate the frequency of occurrence of parafunctional habits in individuals with CP. Sixty-five patients with CP were evaluated through a questionnaire and clinical observation, regarding the following habits: pacifier-sucking, finger-sucking, biting objects, tongue interposition, and bruxism. The results showed that nine (13.8%) patients presented with pacifier-sucking, four (6.1%) showed finger-sucking, 12 (18.4%) had the habit of biting objects, 27 (41.5%) presented with tongue interposition, and 24 (36.9%) had eccentric bruxism. The significance of the presence of oral parafunctional habits in individuals with CP, revealed in this study, justifies the need to establish protocols for adequate prevention and clinical intervention in order to minimize the deleterious consequences that may result from such habits.

Influence of age, sex, and hepatitis C virus infection on peripheral blood lymphocyte subsets in stable kidney transplantation.

BACKGROUND: Young age and hepatitis C virus infection (HCVI) are believed to be risk factors in kidney transplantation recipients. The first group is treated empirically with an intensive immunosuppressive regimen, because it is considered to have high immune alloreactivity. The other cohort usually receives a less intensive regimen to avoid excessive immunosuppressive effects. Our aim was to investigate the influence of age, sex, and HCVI on immune status in stable kidney transplant recipients through measurement of peripheral blood lymphocyte subsets. METHODS: Absolute CD3+, CD3+, CD4+, CD3+, CD8+, CD19+, CD16+ CD3- lymphocyte counts and CD4/CD8 ratios were assessed at five time points in 65 stable kidney allograft patients over 12 months. The subsets were compared according to age, sex, and HCVI of the recipients. RESULTS: An inverse association was observed between recipient age and absolute CD19+ and CD3+ CD4+ lymphocyte counts, which was significant at all time points with respect to CD19+ counts, and at three time points with respect to CD3+ CD4+ counts. A significant positive association was observed between recipient age and absolute CD3- CD16+ lymphocyte counts at three time points. Female recipients showed significantly lower CD3+ CD8+ counts and significantly higher CD4/CD8 ratios than male recipients at four time points. HCVI recipients showed significantly lower CD16+ CD3- counts at four time points. CONCLUSIONS: We observed links between immune status and age, sex and HCVI in stable kidney transplant recipients that could offer new insights into recommendations for maintenance immunosuppression.
