Comparison of Possible Changes in Oxidative Stress, DNA Damage, and Inflammatory Markers in Children/Adolescents Diagnosed with Sluggish Cognitive Tempo and Children/Adolescents Diagnosed with Attention-Deficit/Hyperactivity Disorder

Background: There has been a debate on whether sluggish cognitive tempo (SCT) differs from attention-deficit/hyperactivity disorder (ADHD). Although there have been many studies on metabolic parameters in relation to ADHD, no similar studies have been conducted on patients with SCT. We investigated whether there are differences between SCT and ADHD in terms of these factors. Subjects and Methods: Sixty-two participants with ages ranging from 11 to 18 who have diagnosis of ADHD (33 subjects) and SCT (29 subjects) were included in this study. The parents of all participants completed the 48-item Conners' Parent Rating Scale (CPRS) and the Barkley Child Attention Scale (BCAS) forms, and all participants' blood was taken to compare metabolic, oxidative stress, and antioxidant status of the SCT and ADHD groups. A child and adolescent psychiatrist interviewed the parents and children to assess the diagnosis of SCT and ADHD using standard diagnostic procedures. Results: In the comparison between the SCT and ADHD groups in terms of metabolic parameters, statistically significant differences were found in terms of total oxidant status, total antioxidant status, Oxidative Stress Index, total thiol, native thiol, disulfide, interleukin (IL)-1β, IL-6, and DNA damage (p < 0.05), but not in terms of tumor necrosis factor-α (p > 0.05). Conclusions: Our data showed that these two disorders may be different, but we believe that the data that indicate their differences remain inconclusive overall, but this study may be a potential pathway for future research.

The role of adverse childhood experiences and attachment styles in social anxiety disorder in adolescents

BACKGROUND

Social Anxiety Disorder (SAD) is one of the most common disorders of adolescence and results in marked impairments in social and academic/occupational activities that likely to persist into adulthood. Multiple etiological factors contribute to the development of social anxiety disorder. Two critical factors in presenting with a primary diagnosis of SAD might be adverse childhood experiences (ACEs) and attachment styles. The current study examined how ACEs and attachment styles may be related to SAD in adolescents.

METHODS

60 participants with ages ranging from 11 to 18 (M = 14.6; female = 36), who have a primary diagnosis of SAD and 60 control group adolescents (M = 14.6; female = 30) were included in the study. Both groups completed the Liebowitz Social Anxiety Scale (LSAS), the Childhood Trauma Questionnaire (CTQ), and the Adolescent Relationship Scales Questionnaire (A-RSQ).

RESULTS

After controlling adolescent gender and parental education levels, childhood emotional neglect and income significantly predicted an increased risk for adolescents' SAD diagnosis. Attachment styles did not significantly contribute to predicting adolescents' SAD diagnosis after controlling childhood emotional neglect.

CONCLUSION

The high predictive value of emotional neglect in childhood emphasizes its importance as a risk factor of SAD in adolescence.

The effect of non-diabetic chronic renal failure on olfactory function

OBJECTIVES

In chronic renal failure (CRF), deterioration of glomerular filtration results in accumulation of metabolites in the body which affect all organs. This study was performed to investigate the olfactory functions, and determine if hemodialysis or peritoneal dialysis improves olfactory function in non-diabetic CRF patients.

MATERIALS AND METHODS

The olfactory functions were analyzed in CRF patients not on a dialysis program and had a creatinine level≥2mg/dL, in CRF patients on hemodialysis or peritoneal dialysis, and in healthy controls. Diabetic patients were excluded since diabetes alone is a cause of olfactory dysfunction. The study group consisted of a total of 107 individuals including 38CRF patients on a hemodialysis program, 15 CRF patients on peritoneal dialysis, 30 patients with a creatinine level ≥ 2mg/dL without any need for dialysis, and 24 healthy controls with normal renal functions. Olfactory functions were analyzed with "Sniffin' sticks" test, and the groups were compared for the test results.

RESULTS

All test parameters were impaired in patients with CRF. The median TDI scores of the patients with CRF and the healthy subjects were 24.75 (13-36) and 32.5 (27.75-37.75), respectively, with a statistically significant difference in between (P<0.001). The olfactory functions for the dialysis patients were better than those for the CRF patients not on a dialysis program (P=0.020).

CONCLUSION

Non-diabetic CRF affects olfactory functions negatively. Dialysis improves olfactory functions in those patients.

Is nasal packing required in epistaxis?

OBJECTIVE

To demonstrate the efficacy of identification of bleeding source with nasal endoscopy and cauterization (bipolar or radiofrequency) without nasal packing in adults with posterior epistaxis unable to be treated with nasal packing.

MATERIALS AND METHODS

The average age of patients was 56.16 ± 12.6 (38-72) years, and female-male ratio was 1/5. The average systolic blood pressure was found to be 150 ± 30, while diastolic blood pressure was 90 ± 20 mmHg. Average hemoglobin concentration was 11.2 ± 3.1 (7-15). The bleeding was on the left side in 8 patients and on the right in 4 patients. Probable etiology was considered hypertension crisis (33.3%), use of nasal steroids (8.3%), nasal surgery (8.3%), however in half (50%) of the cases the cause was unidentified. Of the cases, 6 had hypertension, 4 COPD, 10 tobacco use and 5 alcohol use. The source of epistaxis was anterior ethmoidal artery in 2 cases and spheopalatine artery in 10 cases. Two of the cases were treated with radiofrequency coagulation, and ten with bipolar cauterization. Only one of the cases was administered 2 units of packed red blood cells, and one of the cases had postoperative recurrent bleeding. The patients were hospitalized in average 3.2 (2-5) days and no reccurence of hemorrhage was seen in 3 month follow up.

CONCLUSIONS

Dundee epistaxis menagement protocol described by Barnes and Spielman may be applied in adults. Endoscopical detection of the bleeding site and cauterizing the arterial feed source is highly successful in the treatment. Nasal packing may more commonly lead to complication especially in the elderly and in patients with heart and respiratory problems.
