Objective: The aim of this study was to investigate the developmental relationship between adenoid tissue volume and mastoid air cell volume, using a 3D reconstruction technique. Study design: Cross-sectional retrospective study. Subjects and methods: Multislice computed tomography (MSCT) images were obtained using three-dimensional (3D) reconstruction and volume-rendering techniques (VRT). The subjects were 63 boys and 37 girls, 3-16 years of age. The volumes of bilateral mastoid air cells and adenoids marked in axial-coronal-sagittal planes were calculated. The patients were grouped into three categories according to adenoid tissue volume, total mastoid volume (TMV), and age. Results: No significant difference was noted between the right mastoid volume (RMV) and the left mastoid volume (LMV) or between age and sex (p= 0.368; p= 0.549; p= 0.454). The incremental increase in adenoid tissue volume did not correlate with TMV (r= -0.161, r= -0.279, r= 0.015). The incremental increase in TMV did not correlate with the volume of adenoid tissue (r= 0.024, r= 0.148, r= 0.017). Conclusions: No significant correlation was obtained between the incremental increase in adenoid tissue volume and TMV or the incremental increase in TMV and adenoid tissue volume. There does not seem to be a developmental relationship between adenoid tissue volume and TMV. © 2010 Elsevier Ireland Ltd. Source

Abstract Objective The dissociative experiences of patients with bipolar disorder (BD) differ from those of patients with other psychiatric disorders with regard to certain features. The primary goal of this study was to evaluate the relationship between the clinical variables of BD and childhood trauma using the factor structure, psychometric features, and potential subdimensions of the Dissociative Experience Scale (DES). Method This study included 200 BD patients who were in a remission period and 50 healthy volunteers. The BD patients were recruited from two psychiatry clinic departments in Turkey. The sociodemographic data of the two groups and their scores on the DES and Childhood Trauma Questionnaire (CTQ)-28 were compared. Results The overall DES scores and the scores for each DES item accurately and reliably measured dissociation in the BD patients (item-total correlation r scores: >0.20, Cronbach's alpha: 0.95), and a factor analysis revealed two subdimensions of the DES for BD: identity confusion/alteration (SubDES-1) and amnesia and depersonalization/derealization (SubDES-2). Although age at onset of BD was significantly correlated with both subdimensions, illness duration was significantly correlated only with the SubDES-2. Of all the subjects, 19.5% (39/200 patients) were identified as having dissociative experiences by the DES-Taxon (DES-T), and subjects in this subscale (DES-T-positive) had significantly higher total scores on the CTQ-28 as well as higher scores on each subgroup of this scale. The highest CTQ-28 subgroup score was emotional neglect, which was followed by emotional abuse and physical neglect and then sexual abuse and physical abuse. There was a significant correlation between total scores on the CTQ-28 and SubDES-2 but none of the CTQ-28 subscale scores was significantly correlated with either SubDES-1 or SubDES-2. Conclusion The DES sufficiently and reliably identified the experience of dissociative symptoms on the part of BD patients, and a factor analysis revealed two subdimensions of BD on this scale. In particular, DES-T-positive subjects experienced a greater amount of childhood trauma and, as a result, had an earlier age at onset of BD. Additionally, SubDES-2, which was associated with amnesia and depersonalization/derealization, was closely related to illness duration. © 2015 Elsevier B.V. Source

Objective: To investigate whether the recurrent laryngeal nerve (RLN) identification technique use dinthyroidectomy affects RLN paralysis and hypoparathyroidism. Design: Patients were allocated into 2 groups according to the thyroidectomy technique used to identify the RLN: (1) superior-inferior direction, exploring the nerve where it enters the larynx, followed by superior pedicle ligation; and (2) inferior-superior direction, following the inferior pedicle ligation and identifying the nerve in the tracheoesophageal groove. The first and second groups included 67 and 128 patients, respectively. In the first group, 19 patients underwent loboisthmectomy, and 48 underwent total thyroidectomy. In the second group, 42 patients underwent lobo-isthmectomy, and 86 underwent total thyroidectomy. We performed 115 and 214 RLN dissections in the first and second groups, respectively. Setting: Academic tertiary hospital. Patients: The study included 195 consecutive patients, 161 female (82.5%), and 34 male (17.5%), who underwent thyroidectomy for goiter between January 2006 and August 2009. Their mean age was 44.7 years (range, 14-79 years). The mean follow-up was 26 months (range, 12-42 months). Interventions: Unilateral or bilateral total thyroidectomies performed using extracapsular dissection with 2 different RLN identification techniques. Main Outcome Measures: Incidence of hypocalcemia, vocal cord paralysis, hemorrhage, and wound infection. Results: NoRLN paralysis was observed in the first group. In the second group, unilateral RLN paralysis was seen in 2 of 128 patients (1.5%). Groups 1 and 2 included 48 and 86 total thyroidectomies, respectively. Temporary hypoparathyroidismwasobserved in4patients in the first group (8.3%). In the second group, permanent hypoparathyroidism was observed only in 4 patients (4.6%), and temporary hypoparathyroidism was observed in 14 patients (16.2%). Conclusions: Comparing the 2 groups based on the frequencies of RLN paralysis and hypoparathyroidism, we found that complications were significantly lowerin the firstgroup (P<.05) in terms of hypoparathyroidism. The rate of hypoparathyroidism was significantly lower in the thyroidectomies that located the RLN using the superior-inferior approach. In our hands, the superior-inferior approach was a safer technique, in terms of avoiding complications. ©2011 American Medical Association. All rights reserved. Source

Objective: Thrombocytopenia-associated multiple organ failure can lead to high mortality in critically ill children, possibly related to consequences of thrombotic microangiopathy. Plasma exchange therapy may improve thrombotic microangiopathy. The purpose of this observational cohort study is to describe whether there is an association between use of plasma exchange therapy and outcome in the Turkish thrombocytopenia-associated multiple organ failure network.Setting-Interventions: We performed a retrospective cohort analysis in patients with thrombocytopenia-associated multiple organ failure at three different PICUs comparing those who received plasma exchange (+) plus standard therapies with those who did not receive plasma exchange (-) and only received standard therapies.Results: Among 42 of the enrolled patients with thrombocytopenia- associated multiple organ failure, all had a primary or secondary sepsis diagnosis. Fifteen received plasma exchange therapy (PE [+] group) and 27 received standard medical treatment without plasma exchange (PE [-] group). The mean age was 17.69 months (8.24-54.22) in the PE (+) group and 13.46 months (6.47-20.55) in the PE (-) group. Age (p = 0.232), gender (p = 0.206), thrombocyte count (p = 0.09), Organ Failure Index score (p = 0.111), and pediatric logistic organ dysfunction score (p = 0.177) at admission were not statistically different between groups. The overall 28-day mortality was higher in the PE (-) group (70.37%) compared with the PE (+) group (26.67%) (univariate p = 0.006; multivariate controlling for pediatric logistic organ dysfunction, Organ Failure Index, Pediatric Risk of Mortality scores, and neurological failure p = 0.048). Length of stay was increased in the PE (+) group (p = 0.004).Conclusions: The positive association found between use of plasma exchange therapy and improved survival supports the potential of this therapy in Turkish children with thrombocytopeniaassociated multiple organ failure. The positive, although less so, associated treatment effect observed after controlling for illness severity provides further rationale for performing a randomized controlled trial in the pediatric Turkish thrombocytopenia-associated multiple organ failure network. Sample size calculations call for a 100-patient trial with a pre hoc interim analysis after enrollment of 50 patients with thrombocytopenia-associated multiple organ failure.

Objective. The aim of this study was to evaluate the developmental relationship between the volumes of paranasal sinuses and adenoid tissue by using a 3-dimensional (3D) reconstruction technique. Study Design. Cross-sectional study. Setting. Tertiary referral center. Subjects and Methods. Multislice computed tomography (MSCT) images were obtained using 3D reconstructions and a volume-rendering technique (VRT) in 69 boys and 35 girls aged 3 to 16 years, and bilateral maxillary, frontal, and sphenoid sinus volumes, as well as adenoid tissue volume marked in axial-coronal-sagittal planes, were calculated. The patients were grouped in 3 categories according to adenoid tissue volumes, and comparisons were made. Results. There was no significant difference between the right maxillary volume and left maxillary volume (P = .93). No significant difference was noted between the groups in terms of age and gender. There was no significant correlation between frontal, sphenoid, right and left maxillary, or total maxillary sinus volumes in all 3 groups of patients. Conclusion. When classified according to adenoid tissue size, it was observed that increasing adenoid tissue volumes did not significantly affect the development of paranasal sinuses. Developmentally, there are no statistically significant correlations between the volumes of paranasal sinuses and adenoid tissues. © American Academy of Otolaryngology - Head and Neck Surgery Foundation 2011.
