Effect of MAOA rs1465108 polymorphism on susceptibility to substance/alcohol use disorder: a novel PCR-RFLP assay for the detection of MAOA rs1465108.

BACKGROUND: The health and social consequences of substance/alcohol use disorders are harmful. Most of the individuals cannot stop using them due to more likely their genetic background. The current study aimed both to develop a novel PCR-RFLP method for genotyping of MAOA rs1465108 and to analyze the effect of MAOA rs1465108 on the risk of alcohol (AUD), opioid (OUD) or methamphetamine (MUD) use disorders and on the depressive and anxiety symptoms in a Turkish population. METHODS AND RESULTS: A total of 353 individual with AUD (n = 154), OUD (n = 160) or MUD (n = 39) and 109 healthy subjects were included. The intensity of anxiety and depressive symptoms and craving and opioid withdrawal were measured by appropriate scales. Logistic regression analysis revealed no association between MAOA rs1465108 polymorphism and substance/alcohol use disorder (p > 0.05). Healthy subjects (3.0) had significantly lower levels of depressive symptoms than individuals with OUD (27.0), AUD (21.0) and MUD (25.5) groups. The severity of depressive symptoms was significantly higher in OUD as compared to AUD. There was a statistically significant difference between individuals with AUD, OUD and MUD in view of the average ages of first use (17, 19 and 20 years, respectively) (p < 0.05). CONCLUSIONS: The results presented here do not support the hypothesis that MAOA rs1465108 is associated with substance/alcohol use disorders. The intensity of depressive symptoms could be changed according to the abused substance type. A novel PCR-RFLP was developed for genotyping of MAOA rs1465108 polymorphism, which could be a better option for laboratories without high technology equipment.

A case control study investigating the methylation levels of GHRL and GHSR genes in alcohol use disorder.

BACKGROUND: Alcohol use disorder (AUD) is a relapsing disease described as excessive use of alcohol. Evidence of the role of DNA methylation in addiction is accumulating. Ghrelin is an important peptide known as appetite hormone and its role in addictive behavior has been identified. Here we aimed to determine the methylation levels of two crucial genes (GHRL and GHSR) in ghrelin signaling and further investigate the association between methylation ratios and plasma ghrelin levels. METHODS: Individuals diagnosed with (n = 71) and without (n = 82) AUD were recruited in this study. DNA methylation levels were measured through methylation-sensitive high-resolution melting (MS-HRM). Acylated ghrelin levels were detected by ELISA. The GHRL rs696217 polymorphism was analyzed by the standard PCR-RFLP method. RESULTS: GHRL was significantly hypermethylated (P < 0.0022) in AUD between 25 and 50% methylation than in control subjects but no significant changes of GHSR methylation were observed. Moreover, GHRL showed significant positive correlation of methylation ratio between 25 and 50% with age. A significant positive correlation between GHSR methylation and ghrelin levels in the AUD group was determined (P = 0.037). The level of GHRL methylation and the ghrelin levels showed a significant association in the control subjects (P = 0.042). CONCLUSION: GHSR and GHRL methylation levels did not change significantly between control and AUD groups. However, GHRL and GHSR methylations seemed to have associations with plasma ghrelin levels in two groups. This is the first study investigating the DNA methylation of GHRL and GHSR genes in AUD.

Autologous peripheral blood stem cell mobilization and apheresis in pediatric patients with cancer: A single-center report of 64 procedures.

BACKGROUND: The published experience concerning autologous peripheral blood stem cell collection in children is very limited. METHODS: The data of pediatric patients who underwent autologous stem cell mobilization and apheresis between January 2011 and April 2020 were analyzed retrospectively. RESULTS: We studied retrospectively 64 mobilization and apheresis procedures in 48 pediatric patients (34 males, 14 females), mean age of 7.31 ± 5.38 (range, 1.5-19.7) years, the underlying disease was mostly neuroblastoma (NBL). The body weight of 21 patients (43.75%) was 15 kg or less. The targeted autologous peripheral stem cell apheresis (APSCA) was successfully achieved in 98% of patients. Neuroblastoma patients were younger than the rest of the patients and underwent apheresis after receiving fewer chemotherapy cycles than others and all of them mobilized within the first session successfully. Plerixafor was added to mobilization in nine heavily pretreated patients (18.7%), median two doses (range, 1-4 doses). 11 patients (22.9%) underwent radiotherapy (RT) before mobilization with doses of median 24 Gy (range, 10.8-54.0 Gy). Patients with RT were older at the time of apheresis and had received more chemotherapy courses than patients without RT. As a result, patients with a history of RT had significantly lower peripheral CD34+ cells and CD34+ yields than those without RT. In 17 patients (35.4%), 22 different complications were noted. The most common complications were catheter-related infections (n:10, 20.8%), followed by catheter-related thrombosis in eight patients (16.7%). CONCLUSIONS: Patients who had far less therapy before apheresis were more likely to mobilize successfully. Our study provides a detailed practice approach including complications during APSCA aiming to increase the success rates of apheresis in transplantation centers.

Ghrelin and impulsivity relationship in alcohol-dependent patients and healthy individuals.

AIMS: Abundant research indicates that ghrelin hormone levels are associated with alcohol use and addiction. One of the mediators of this association may be impulsivity, which is one of the common traits observed in alcohol addiction and some eating disorders. This study evaluated participants with alcohol dependency and healthy volunteers to determine whether trait impulsivity and ghrelin levels are associated. METHODS: This study analyzed trait impulsivity scores and fasting serum ghrelin levels of 44 males with alcohol dependency and 48 healthy male participants. The Barratt Impulsiveness Scale and the UPPS Impulsive Behaviour Scale (UPPS) were used to measure trait impulsivity levels. Penn Alcohol Craving Scale and Yale Brown Obsessive Compulsive Drinking Scale for heavy drinking were used to assess craving at the baseline and after the detoxification period. RESULTS: Alcohol-dependent patients' fasting ghrelin levels were significantly higher than that of healthy participants. Ghrelin plasma levels were positively correlated with UPPS total impulsivity scores and sensation-seeking among healthy individuals. In alcohol-dependent participants, there was a positive correlation between UPPS urgency scores obtained at the baseline and fasting ghrelin levels before and after the detoxification period. CONCLUSIONS: Ghrelin-impulsivity relationship could be observed in certain dimensions of impulsivity in both alcohol-dependent and healthy individuals and even independent of the effect of alcohol. Although the associated impulsivity dimensions differ in different groups, the results are parallel to other studies in terms of demonstrating the relationship between ghrelin and impulsivity.

Effect of PDYN and OPRK1 polymorphisms on the risk of alcohol use disorder and the intensity of depressive symptoms.

AIMS: The dynorphin (DYN)/Kappa Opioid Receptor (KOR) system has been suggested to be involved in both negative affective states and the action of alcohol. The present study was undertaken to explore whether the DYN/KOR system genes, PDYN and OPRK1, influence on individual differences in the intensity of depressive symptoms at admission as well as the risk of alcohol use disorder (AUD) risk in a sample of 101 individuals with AUD and 100 controls. METHODS: PDYN (rs2281285, rs2225749 and rs910080) and OPRK1 (rs6473797, rs963549 and rs997917) polymorphisms were analyzed by PCR-RFLP. The intensity of depressive and anxiety symptoms and craving were measured by the Beck Depression Inventory-II (BDI-II), Beck Anxiety Inventory (BAI), and Penn Alcohol Craving Scale, respectively. RESULTS: A significant association between the risk of AUD and OPRK1 rs6473797 (P < 0.05) at the gene level. OPRK1 rs6473797 CC genotype was found to lead to a 3.11 times greater alcohol dependence risk. In addition, the BDI-II score of the OPRK1 rs963549 CC genotype was found to be significantly lower (20.9 ± 11.2, min: 1.0, max: 48.0) than that of the CT + TT genotypes (27.04 ± 12.7, min: 0.0, max: 49.0) (t: -2.332, P = 0.022). None of the PDYN polymorphisms were associated with BDI-II score. CONCLUSION: Variations in the KOR are associated with the risk of AUD and the intensity of depressive symptoms at admission at the gene level in Turkish males. On the other hand, PDYN gene seemed not to be associated with AUD, depression, anxiety, and craving.

Extended clinical and immunological phenotype and transplant outcome in CD27 and CD70 deficiency.

Biallelic mutations in the genes encoding CD27 or its ligand CD70 underlie inborn errors of immunity (IEIs) characterized predominantly by Epstein-Barr virus (EBV)-associated immune dysregulation, such as chronic viremia, severe infectious mononucleosis, hemophagocytic lymphohistiocytosis (HLH), lymphoproliferation, and malignancy. A comprehensive understanding of the natural history, immune characteristics, and transplant outcomes has remained elusive. Here, in a multi-institutional global collaboration, we collected the clinical information of 49 patients from 29 families (CD27, n = 33; CD70, n = 16), including 24 previously unreported individuals and identified a total of 16 distinct mutations in CD27, and 8 in CD70, respectively. The majority of patients (90%) were EBV+ at diagnosis, but only ∼30% presented with infectious mononucleosis. Lymphoproliferation and lymphoma were the main clinical manifestations (70% and 43%, respectively), and 9 of the CD27-deficient patients developed HLH. Twenty-one patients (43%) developed autoinflammatory features including uveitis, arthritis, and periodic fever. Detailed immunological characterization revealed aberrant generation of memory B and T cells, including a paucity of EBV-specific T cells, and impaired effector function of CD8+ T cells, thereby providing mechanistic insight into cellular defects underpinning the clinical features of disrupted CD27/CD70 signaling. Nineteen patients underwent allogeneic hematopoietic stem cell transplantation (HSCT) prior to adulthood predominantly because of lymphoma, with 95% survival without disease recurrence. Our data highlight the marked predisposition to lymphoma of both CD27- and CD70-deficient patients. The excellent outcome after HSCT supports the timely implementation of this treatment modality particularly in patients presenting with malignant transformation to lymphoma.

Clinical Profile and Outcomes of Primary Immunodeficiency and Malignancy in Childhood at a Tertiary Oncology Center in Developing Country.

Primary immune deficiencies are a group of heterogenous genetic disorders characterized by frequent infections, autoimmunity and malignancy. In this study, we aimed to evaluate clinical characteristics, outcomes of children with malignancy developed on background of primary immunodeficiency and compare survival rates of patients between malignant lymphoma with primary immunodeficiency and without immunodeficiency from tertiary oncology center in a developing country. A total 23 patients with primary immunodeficiency and malignancy were evaluated retrospectively. A total of 26 malignancies (first or second) in 23 patients were determined. The median age at the time of the first malignancy was 8 years (ranges 2-18 years) with increased male ratio (M/F:14/9). Non-Hodgkin lymphoma (n = 17; 65%) was the most common malignancy, followed by Hodgkin lymphoma (n = 5), anaplastic ependymoma (n = 1), spinal glioblastoma multiforme (n = 1), retinoblastoma (n = 1) and intracranial hemangiopericytoma (n = 1). The median follow-up time of patients was 25 months (ranges between 1 and 189 months). The 5-year overall survival rate of patients with malignant lymphoma associated with primary immunodeficiency (41%) were lower than immunocompetent patients with malignant lymphoma (80%) (p = 0.000). The 5-year overall survival of patients was diagnosed between 2021 and 2013 years (62%) was higher than previous years (22%) (p = 0.03). In conclusion, non-Hodgkin lymphomas were the most common histopathologic type in patients with malignancy associated with primary immunodeficiency in the present study. The survival of patients with malignant lymphoma associated with primary immunodeficiency has improved in recent years, yet it is still lower than immunocompetent patients with lymphoma and new targeted drugs are required for better survival rates.

The relation between staging fluorine-18 fluorodeoxyglucose positron emission tomog- raphy/computed tomography metabolic parameters and tumor necrosis rate in pediatric osteosarcoma patients

Background/aim: The aim of this study was to investigate the contribution of fluorine-18 (F-18) fluorodeoxyglucose (FDG) positron emission tomography/computed tomography (PET/CT) imaging in staging of pediatric osteosarcoma patients and also to evaluate the ability of metabolic parameters from the primary tumor to predict tumor necrosis rate (TNR). Material and methods: F-18 FDG-PET/CT imaging was performed in staging 37 pediatric osteosarcoma patients. The metabolic pa- rameters SUVmax (maximum standardised uptake value), MTV (metabolic tumour volume), and TLG (total lesion glycolysis) were measured from the primary tumor. TNR level of the primary tumor was histopathologically measured after standard neoadjuvant chemotherapy treatment. The contribution of F-18 FDG-PET/CT to staging of pediatric osteosarcoma patients and the accuracy of metabolic parameters of the primary tumor to predict TNR were analized by regression analysis. Results: MTV and TLG of the primary tumor were found to efficiently predict histopathologic TNR, whereas SUVmax was not (P = 0.012, P = 0.027, P = 0.25, respectively). Also 5 of 12 patients (41.6%) who were initially defined as localised osteosarcoma were upstaged in consequence of staging F-18 FDG-PET/CT findings. Conclusion: F-18 FDG-PET/CT staging in pediatric osteosarcoma patients can effectively distinguish metastatic-localised disease. MTV and TLG values are important parameters, which can efficiently be used to predict TNR.

Paratesticular Rhabdomyosarcoma Associated with Tuberculosis.

We report a 16-year-old male patient diagnosed with paratesticular rhabdomyosarcoma and mediastinal tuberculous lymphadenitis. The differential diagnosis between high or early stage of rhabdomyosarcoma and tuberculosis (TB) was critical in this patient without a history of TB. Unexpected lymphadenopathies detected during the staging of patients with malignancy should be carefully evaluated, and TB should be taken into consideration in the differential diagnosis especially in underdeveloped and developing countries. Unnecessary additional treatments increase the rate of mortality and morbidity because of upstaging of cancer. Further, TB reactivation can be seen during chemotherapy because of immunosuppression.

Irinotecan and temozolamide treatment for relapsed Ewing sarcoma: a single-center experience and review of the literature.

Long-term survival in relapsed Ewing sarcoma (ES) is less than 20%. Encouraging results have been reported with irinotecan and temozolomide combinations (IRN/TMZ). We aimed to share our experience and compare it with previously published studies using this combination to treat relapsed ES. We retrospectively evaluated 20 patients treated with a combination of IRN (20 mg/m(2)/d × 5 for 2 weeks) and temozolomide (100 mg/m(2)/d × 5). Patients received a total of 97 courses. An objective response was achieved in 11 patients (55%) and maintained for a median of 12 months. Five patients were alive for a median of 12 months. Median time to progression was 5.5 (2-57) months. After the IRN/TMZ treatment, 1-year overall and event-free survival rates were 54.2% and 44.4%, respectively. Grade 3-4 toxicities included diarrhea (9.2%), neutropenia (11.3%), and thrombocytopenia (6.2%). Three retrospective trials were found in our literature review, which used an IRN/TMZ combination to treat ES. There was one other study which retrospectively evaluated the efficacy of vincristine, IRN, and TMZ combination in relapsed ES. A total of 81 patients were treated with IRN/TMZ in four studies including ours. The objective response rate was 55.1%, and median time to progression ranged from 5.5 to 8.3 months. Twenty-six (7.5%) of a total of 346 courses were associated with grade 3-4 diarrhea. Grade 3-4 neutropenia and thrombocytopenia were reported in 9.2% and 7.2% of the courses, respectively. Results showed that an IRN/TMZ combination is effective and tolerable in patients with relapsed ES.

Anthropometric and Biochemical Assessment of Nutritional Status in Pediatric Cancer Patients.

Children are at greater risk for malnutrition due to increased needs of nutrients to obtain appropriate growth, and they exhibit elevated substrate needs due to cancer and its treatment. This study aimed to report anthropometric and biochemical evaluation of nutritional status in children with cancer at initial presentation and during treatment. A prospective, controlled study was performed in the pediatric oncology department of a tertiary care center. Control group consisted of the siblings of patients. Weight, height, body mass index, triceps skinfold thickness, and serum levels of total protein, albumin, prealbumin, serum lipids, trace minerals, C-reactive protein (CRP), and vitamins were compared in patients and controls at initial presentation and at 6th month after the onset of treatment. According to weight for height, the frequency of malnutrition was 16% at initial presentation and 22% at 6th month. Triceps skinfold thickness was significantly thinner in patients than controls at both measurements. Patients had lower levels of prealbumin, albumin, iron, folate, zinc, and vitamin C and higher levels of ferritin, vitamin B12, and copper. Serum CRP levels were significantly higher in cancer patients at initial presentation and seemed to be correlated with copper levels. Compared with other patients, malnourished patients had significantly higher levels of vitamin B12 at 6th month. Results of the current study demonstrate that trace minerals, vitamins, and anthropometric measures may yield important clues for nutritional status and disease activity in pediatric oncology patients. However, validation and updating these potential markers warrant further trials on larger series.

Magnetic Resonance Imaging Findings in Childhood Period Nasopharynx Cancer.

BACKGROUND: Nasopharyngeal carcinoma is a rarely seen tumor in childhood. It is mostly detected late as the clinical features are similar to other childhood tumors which affect the nasopharynx and adenoidal hypertrophy. Therefore, the radiological features of childhood tumors of the nasopharynx must be well known. The aim of this study was to investigate the contribution of MR imaging features of childhood nasopharynx cancer. MATERIAL/METHODS: The study included 10 nasopharyngeal carcinoma patients under the age of 18 years who presented at hospital between February 2008 and March 2014 and who had tissue diagnosis and MRI of the nasopharynx region. The MRI scans were evaluated by two radiologists. Loco-regional spread, asymmetry, signal intensity of the tumors, and lymph nodes were evaluated. RESULTS: In all the patients there was a mass which narrowed the nasopharynx. In all cases, unilateral mastoid opacification was observed. In 9 cases (90%), parapharyngeal extension was found. In 8 cases (80%), the mass showed an extension into the nasal cavity or oropharynx. In 5 cases (50%), there was an involvement of the skull base. In 3 patients (30%), an extension to the masticator space and pterygopalatine fossa was found. There were enlarged cervical lymph nodes bilaterally in 10 cases (100%). In 4 cases (40%), a lateral retropharyngeal lymph node was detected. CONCLUSIONS: Childhood nasopharyngeal cancers are often diagnosed at an advanced stage. MR imaging can be helpful in diagnosis and differential diagnosis of childhood nasopharynx cancer from other diseases of the nasopharynx.

Gastrointestinal stromal tumor in a newborn diagnosed in prenatal period: a case report and review of literature.

Gastrointestinal stromal tumor (GIST) is the most common mesenchymal neoplasm of the gastrointestinal tract. Only 1.5% to 2% of all GISTs are observed in children and adolescents. Most of the pediatric cases are between 10 and 18 years of age, with a median age of 13 years. GIST is extremely rare in the newborn period. We could find only 5 reports on the neonatal cases. Herein, we have reported a case with abdominal tumor that was identified by prenatal ultrasonography and magnetic resonance imaging, and diagnosed as GIST on the seventh day of life. We have also reviewed the neonatal GIST cases reported in the English literature.

The role of proangiogenic cytokines in predicting sepsis in febrile neutropenic children with cancer.

BACKGROUND: We assessed the relationship between sepsis occurrence and the serum levels of angiopoietin (Ang-1, Ang-2), vascular endothelial growth factor (VEGF) and soluble fms-like tyrosine kinase-1 (sFlt-1) in pediatric patients with cancer-related febrile neutropenia. METHODS: Fifty-two children with malignant tumors who experienced 86 episodes of febrile neutropenia (FN) were examined between June 2016 and June 2018. Each FN episode was considered a separate event and the total number of FNs were recorded (86 FN episodes = FN group). The control group consisted of 21 healthy children. Ang-1, Ang-2, VEGF-A and sFlt-1 were measured at the baseline and 48th hour of each FN episode -alongside routine characterization of inflammation (C-reactive protein; white blood cell and absolute neutrophil count). RESULTS: Among the episodes, 29 (34.5%) developed sepsis while 57 were classified as non-complicated FN. The baseline values of patients and controls were significantly different for Ang-1, Ang-2, VEGF and sFlt-1 values (all, p < 0.05). In the subgroup with sepsis, Ang-2 values were higher than in the subgroup without sepsis (p = 0.017). In predicting sepsis, Ang-2 had 60.7% sensitivity and 66.7% specificity at the 74.6 cut-off value (AUC: 0.662 [95%CI: 0.541 - 0.783], p = 0.022), Ang-2 / Ang-1 ratio had 65.5% sensitivity and 60.0% specificity at the 0.405 cut-off value (AUC: 0.633 [95%CI: 0.513 - 0.753], p = 0.046). CONCLUSIONS: Our results reveal that Ang-2 and Ang-2/Ang-1 were higher in the sepsis group and Ang-2 might be a biomarker to indicate the risk of sepsis in patients with FN and/or cancer.

Evaluating Postoperative Outcomes and Investigating the Usefulness of EU-TIRADS Scoring in Managing Pediatric Thyroid Nodules Bethesda 3 and 4

Objective: The aim was to assess postoperative outcomes in pediatric thyroid nodules with atypia of undetermined significance (AUS/FLUS) or suspicious for a follicular neoplasm (SFN) and their respective the European-Thyroid Imaging Reporting and Data System (EU-TIRADS) scores. Methods: Forty-four pediatric patients at a single center with thyroid nodules classified as AUS/FLUS or SFN from August 2019 to December 2022 were retrospectively reviewed. Data on demographics, thyroid function, nodule size, and ultrasonographic features were collected. Postoperative pathologies were categorized into benign, low-risk, and malignant neoplasms according to the World Health Organization 2022 criteria, and EU-TIRADS was used for retrospective radiological scoring. Results: Among 21 (47.7%) of patients who had surgical intervention, 72% had Bethesda 3 and 28% had Bethesda 4 thyroid nodules. Post-surgical histopathological classifications were 43% benign, 19% low-risk, and 38% malignant. Of note, EU-TIRADS 3 and 5 scores were present in 44% and 56% of the benign cases, respectively. Malignant cases tended to produce higher EU-TIRADS scores, with 64% rated as EU-TIRADS 5. Bethesda category 4 nodules had a 66% malignancy rate, significantly higher than the 27% in category 3. Conclusion: A substantial proportion of histologically benign cases were classified as EU-TIRADS 5, suggesting that EU-TIRADS may lead to unnecessary biopsies in benign cases. Malignant cases were more likely to have a higher EU-TIRADS score, indicating a positive correlation with malignancy risk, particularly in Bethesda 4 cases. However, the EU-TIRADS system's predictive value for malignancy in Bethesda 3 cases was poorer.

Comparison of filgrastim and lenograstim in pediatric solid tumors.

PURPOSE: Chemotherapy-induced febrile neutropenia (FEN), which causes treatment delays or chemotherapy dose reductions, is a serious side effect of cancer treatment. In Turkey, recombinant G-CSF (rG-CSF) has been used since 2000 to control neutropenia. The purpose of this prospective randomized study is to compare the effectiveness, toxicities and the cost of these two drugs in children. METHODS: Between April and December 2008, 29 patients were administered 40 courses of chemotherapy in each arm. A randomized crossover study was designed. All patients were administered rG-CSF 24 hours after the last day of chemotherapy as a secondary prophylaxis. Complete blood counts as well as peripheral blood progenitor (CD34+) cell levels were measured before G-CSF treatment and on the fifth and the seventh day of treatment. RESULTS: The median duration of neutropenia, FEN, the length of hospitalization, the incidence of FEN, and documented infection was not different between the two rG-CSF treatment groups. Erythrocyte and platelet transfusion rates were also similar. After 7 days, the mean leukocyte (WBC [white blood cell]) and neutrophil count (ANC [absolute neutrophil count]), hemoglobin and platelet levels were not significantly different. However, the CD34+ cell level was significantly higher in the lenograstim group. Lenograstim was also more expensive than filgrastim. No serious side effects were reported for either rG-CSF treatment. CONCLUSIONS: There is no difference following the administration of either lenograstim or filgrastim for the duration of neutropenia, FEN or hospitalization for pediatric cancer patients. For stem cell mobilization, lenograstim was superior to filgrastim.

Association of PDYN 68-bp VNTR polymorphism with sublingual buprenorphine/naloxone treatment and with opioid or alcohol use disorder: Effect on craving, depression, anxiety and age onset of first use.

In this case-control study (423 Turkish subjects), the functional pro-dynorphin (PDYN) 68-bp VNTR polymorphism was genotyped in opioid users receiving sublingual buprenorphine/naloxone treatment (SBNT; n = 129, 119 males and 10 females), in opioid users (OUD; n = 99, 90 males and 9 females), in alcohol users (AUD; n = 75, 75 males) and in controls (n = 120, 109 males and 11 females) to determine the effect of this polymorphism on different treatment responses, heroin or alcohol dependence as well as age onset of first use. The PDYN 68-bp alleles were determined based on the number of repeats and genotypes were classified as "short/short (SS)", "short-long (SL)" and "long-long (LL)". The intensity of craving, withdrawal, depression and anxiety were measured by the Substance Craving Scale (SCS), the Clinical Opiate Withdrawal Scale (COWS), the Beck Depression Inventory-II (BDI-II) and Beck Anxiety Inventory (BAI), respectively. Healthy controls (5.5 ± 5.8) had significantly lower levels of depressive symptoms compared to OUD (25.4 ± 13.5), AUD (22.5 ± 11.3) and SBNT (19.29 ± 12.2) groups. In OUD group, the LL genotype was associated with decreased intensity of anxiety and depressive symptoms than the SS+SL genotype. The BDI-II scores for PDYN VNTR genotypes within the 4 groups were analysed by two-way ANOVA and statistical differences were found for the groups. SBNT group had significantly lower COWS score than OUD group (1.00 versus 3.00). There were statistically significant differences in the median BAI (11 versus 24) and BDI-II scores (17.5 versus 25) between OUD and SBNT groups, supporting the antidepressant and anxiolytic effects of SBNT in persons with OUD.

Assessment of the mode of anger expression in alcohol dependent male inpatients.

AIMS: To assess the relationships between trait anger (T-Anger) and anger expression styles and emotional states-suicide probability, depression, state and trait anxiety and self-esteem--in alcohol-dependent inpatients. METHODS: The patients included in this study were 142 male inpatients with alcohol dependence according to the Diagnostic and Statistical Manual of Mental Disorders (DSM-IV) criteria. The Suicide Probability Scale, the Coopersmith Self-Esteem Inventory, the Beck Depression Inventory, the Beck Hopelessness Scale, the Spielberger State-Trait Anxiety Scales, and the T-Anger and Anger Expressions Scales were used for the assessment of the emotional states of the patients. Pearson correlation, analysis of variance and linear regression were used in the statistical analysis. RESULTS: There were significant correlations between suicide probability, depression, state and the trait anxiety, and the T-Anger and all of the anger expression subscales. The presence of high probability for suicide was related to a high level of T-Anger, Anger-out and Anger-in. Finally, a low level of hopelessness was associated with a high level of T-Anger, and a high level of the trait anxiety was associated with a low level of the Anger Control (AEX-Con). CONCLUSION: The findings indicated that suicide probability, hopelessness and trait anxiety predict T-Anger levels and anger expression styles. Therefore, anxiety, hopelessness and suicide probability must be considered as risk for anger and anger expressions in alcohol-dependent patients. Furthermore, alcohol treatment programmes should attach importance to anger management and AEX-Con training.

Sports participation and quality of life in individuals with visual impairment.

BACKGROUND: The positive effects of sports participation on health can be an important issue for rehabilitation of visually impaired individuals. AIMS: Our aim was to determine the relationship between sports participation and quality of life in individuals with visual impairment. METHODS: The study included 100 athletes who participated in national games for people with visual impairment and 100 subjects who did not participate in sports as the control group. The two groups were matched according to age, gender, visual acuity and visual field. The Short-Form Health Survey (SF-36) was applied for assessment of quality of life. RESULTS: All subjects had best corrected visual acuity less than 6/60 and/or visual field less than central 10 degrees in radius in the better eye. The sociodemographic characteristics of the study and control groups were similar except the level of education being higher in the athlete group and level of income higher in the control group. All of the SF-36 scores were higher among athletes compared to controls. Duration of sports activities (years) was positively correlated with Physical Functioning score. There were no significant relations between SF-36 scores and weekly sports participation time (hours). Athletes who had visual loss at an earlier age had better scores in Physical Functioning and Role Limitations due to Physical Problems. CONCLUSIONS: Sports activities had positive relationships with all domains of the quality of life in individuals with visual impairment. Thus, appropriate sports activities would increase the success of rehabilitation programs and their quality of life.

Treatment results of the Ewing sarcoma of bone and prognostic factors.

BACKGROUND: The purpose of this study is to assess the clinical outcome of patients with ESFT of the bone treated with the European Intergroup Cooperative Ewings Sarcoma Study (EICESS)-92 treatment protocol at a single center, and to identify prognostic factors. METHODS: Ninety-eight patients younger than 18 years of age, diagnosed with ESFT of the bone between 1992 and 2005, were analyzed retrospectively. RESULTS: Eighty-seven patients were treated with the EICESS-92 protocol. The median follow-up was 105 +/- 38 months. The 5-year event-free survival (EFS) survival rate was 40%, the 5-year overall survival (OS) rate was 47%. For non-metastatic disease, the rates of 5-year EFS and OS were 45% and 51%. These rates were 18% and 27%, for metastatic disease. The 5-year EFS and OS rates were 17% and 30%, respectively for females. For males, theses rates were 45% and 48%. Of 87 patients, 52 were admitted with primary extremity lesions. Distant metastasis was detected in 48% of patients with a metaphyseal tumor. In patients with diaphyseal lesions, it was 17%. The 5-year EFS and OS were 35% and 43%, respectively. In non-metastatic disease, these measures were 43% and 50%, whereas in metastatic disease, they were 20% and 27%. In patients with a lesion originating from metaphysis, the 5-year EFS was 17%, and the 5-year OS was 29%, for patients with a diaphyseal lesion, these values were 50% and 54%. CONCLUSION: The presence of metastasis was closely related with metaphyseal tumors. The localization of tumor in the bone (i.e., diaphyseal or metaphyseal) and gender of patients seem to have prognostic importance.
