Identification of the molecular etiology in rare congenital hemolytic anemias using next-generation sequencing with exome-based copy number variant analysis.

OBJECTIVES: In congenital hemolytic anemias (CHA), it is not always possible to determine the specific diagnosis by evaluating clinical findings and conventional laboratory tests. The aim of this study is to evaluate the utility of next-generation sequencing (NGS) and clinical-exome-based copy number variant (CNV) analysis in patients with CHA. METHODS: One hundred and forty-three CHA cases from 115 unrelated families referred for molecular analysis were enrolled in the study. Molecular analysis was performed using two different clinical exome panels in 130 patients, and whole-exome sequencing in nine patients. Exome-based CNV calling was incorporated into the traditional single-nucleotide variant and small insertion/deletion analysis pipeline for NGS data in 92 cases. In four patients from the same family, the PK Gypsy variant was investigated using long-range polymerase chain reaction. RESULTS: Molecular diagnosis was established in 86% of the study group. The most frequently mutated genes were SPTB (31.7%) and PKLR (28.5%). CNV analysis of 92 cases revealed that three patients had different sizes of large deletions in the SPTB and six patients had a deletion in the PKLR. CONCLUSIONS: In this study, NGS provided a high molecular diagnostic rate in cases with rare CHA. Analysis of the CNVs contributed to the diagnostic success.

Involutive sweeping surfaces with Frenet frame in Euclidean 3-space.

In this paper we first define the involutive sweeping surfaces as a new surface form. We then investigate singularity, Gaussian and mean curvatures of these surfaces. By calculating the Gaussian and mean curvatures of the involutive sweeping surfaces, we find necessary conditions of being flat or minimal of these surfaces. Also, we analyze the necessary and sufficient conditions for parameter curves on the surface to be asymptotic, geodesic. Then we investigate the special case that the parameter curves are lines of curvature on the surface. Finally, we illustrate our method of calculation by presenting an example.

Anxiety and theory of mind: A moderated mediation model of mindfulness and gender.

This study aimed to examine the relationship between gender, anxiety, mindfulness, and theory of mind (ToM). It was also aimed to investigate the mediating role of mindfulness in the relationship between anxiety and ToM. Additionally, the moderating role of gender in the relevant relationships was examined. The sample consisted of 323 people, including 260 (80.5%) females and 63 (19.5%) males, aged between 18-62 years. Data were collected by the Reading the Mind in the Eyes Test, the State-Trait Anxiety Inventory II, and the Mindful Attention Awareness Scale. It was found that ToM and anxiety levels were statistically significantly higher in women than men. In the regression analysis, it was detected that mindfulness predicts the 7% variance in ToM. The second predictor of ToM was found as anxiety, and both predictors explained the 9% variance in ToM. In the mediating analysis, it was found that mindfulness has a mediating role in the relationship between anxiety and ToM. In the moderated mediation analysis, it was determined that the pathway between anxiety and ToM was moderated by gender; the moderating role of gender also was found between mindfulness and ToM. In light of these findings, experimental future studies can be suggested with clinical samples for a better understanding of the relationships between gender, anxiety, mindfulness, and ToM.

Nitric oxide, asymmetric dimethylarginine, symmetric dimethylarginine and L-arginine levels in psychotic exacerbation of schizophrenia and bipolar disorder manic episode.

OBJECTIVES: To examine the changes in nitric oxide (NO), asymmetric dimethylarginine (ADMA), symmetric dimethylarginine (SDMA), and L-arginine levels in schizophrenia during acute psychotic exacerbation and in bipolar disorder during mania and to compare those changes to healthy controls. METHODS: Thirty schizophrenia patients with acute psychotic exacerbation and 30 bipolar disorder patients with mania, who attended the Psychiatry Department,  Erenköy Hospital for Mental and Nervous Diseases, Istanbul, Turkey, in 2010. Thirty healthy controls were included. The diagnosis was made using the Structured Clinical Interview for Axis I Disorders (SCID-I) interviews. Patients' demographic data were recorded, and NO, SDMA, L-arginine, and ADMA levels were studied. RESULTS: Nitric oxide levels in schizophrenia patients were significantly lower than the control group. Nitric oxide levels in the bipolar group were lower than the control group but the difference was not statistically significant. The levels of SDMA, ADMA, and L-arginine were found to be significantly higher in schizophrenia and bipolar disorder patients than the control group. The disease duration was slightly negatively correlated with NO levels in bipolar patients. In schizophrenia patients, the disease severity was slightly positively correlated with NO levels. CONCLUSION: Significant changes in NO, SDMA, ADMA, and L-arginine levels in schizophrenia and bipolar disorder patients suggest that NO and inhibitors of NO might be implicated in the neurobiology of schizophrenia and bipolar disorder.

Synthesis of magnetic halloysite nanotube-based molecularly imprinted polymers for sensitive spectrophotometric detection of metoclopramide in urine samples.

A novel molecularly imprinted polymer was synthesized on magnetic halloysite nanotube via surface initiated reversible addition-fragmentation chain transfer polymerization in the presence of 2-aminoethylmethacrylamide, 2-Cyano-2-propyl benzodithioate, ethylene glycol dimethacrylate (EGDMA) and azobis(isobutyronitrile) for sensitive and selective spectrophotometric determination of metoclopramide in urine samples. The synthesized imprinted polymer was characterized by several surface characterization techniques and the results indicated there was a thin polymer network on the magnetic halloysite nanotube. The rebinding properties of the molecularly imprinted magnetic halloysite nanotube were also investigated in detail and the maximum adsorption capacity and imprinting factor were found to be 37.8 mg/g and 4.51, respectively. The application of the proposed method was carried out by enrichment and spectrophotometric determination of metoclopramide via formation of a charge transfer complex between picric acid and eluted metoclopramide. Under the optimized conditions, the calibration curve was linear in the concentration range of 5.0-150.0 ng/mL and the limit of detection and the limit of quantification were calculated to be 1.5 ng/mL and 4.95 ng/mL, respectively. The inter-day and intra-day precisions were below 5% and recoveries were between 92.8% and 99.2%. The results showed that the proposed method increased the sensitivity and selectivity for spectrophotometric determination of metoclopramide.

Efficient and selective separation of metronidazole from human serum by using molecularly imprinted magnetic nanoparticles.

Magnetic molecularly imprinted nanoparticles were prepared through surface-initiated reversible addition fragmentation chain transfer polymerization by using metronidazole as a template. The molecularly imprinted magnetic nanoparticles were characterized by attenuated total reflection Fourier transform infrared spectroscopy, X-ray photoelectron spectroscopy, transmission electron microscopy, X-ray diffraction, and vibrating sample magnetometry. The adsorption characteristics were also investigated and the kinetics of the adsorption of metronidazole on the imprinted nanoparticles were described by the second-order kinetic model with the short equilibrium adsorption time (30 min). The adsorption isotherm was well matched with the Langmuir isotherm in which the maximum adsorption capacity was calculated to be 40.1 mg/g. Furthermore, the imprinted magnetic nanoparticles showed good selectivity as well as reusability even after six adsorption-desorption cycles. The imprinted magnetic nanoparticles were used as a sorbent for the selective separation of metronidazole from human serum. The recoveries of metronidazole from human serum changed between 97.5 and 99.8% and showed similar sensitivity as an enzyme-linked immunoassay method. Therefore, the molecularly imprinted magnetic nanoparticles might have potential application for the selective and reliable separation of metronidazole from biological fluids in clinical applications.

Evaluation of childhood trauma with respect to criminal behavior, dissociative experiences, adverse family experiences and psychiatric backgrounds among prison inmates.

OBJECTIVE: To evaluate childhood trauma in relation to criminal behavior, dissociative experiences, adverse family experiences during childhood and psychiatric backgrounds among prison inmates. METHODS: In total, 200 prison inmates were included in this questionnaire-based study. Data on demographic characteristics, adverse family experiences during childhood and psychiatric backgrounds were collected via face-to-face interviews, and a psychometric evaluation was conducted using the Childhood Trauma Questionnaire (CTQ-28) and Dissociative Experiences Scale (DES). RESULTS: Several historical items were more common in females than in males including family history of psychiatric disease (23.0% vs. 13.0%, p = 0.048), a personal history of psychiatric disease (51.0% vs. 29.0%, p < 0.001), and previous suicide attempts (49.0% vs. 25.0%, p < 0.001). In male inmates, in contrast, there were higher rates of substance abuse (48.0% vs. 29.0%, p < 0.001) and previous convictions (50.0% vs. 25.0%, p < 0.001). Males had a younger age at first crime (24.9 ±â€¯8.9 years vs. 30.3 ±â€¯9.2 years, p < 0.001), whereas females had higher rates of violent crimes (69.2% vs. 30.8% p < 0.001) and higher CTQ total scores (51.9 ±â€¯20.9 vs. 46.2 ±â€¯18.9, p = 0.04). A significant relationship of CTQ total score was noted with age at first offense (ß = 0.772, p < 0.001) but not with sentence length (ß = 0.075, p = 0.292). There were also possible mediating roles of psychiatric problems, adverse family experiences and DES in the relationship between CTQ and age at first offense. CONCLUSION: In conclusion, our findings revealed a high prevalence of and significant associations among childhood trauma, dissociative experiences, adverse family experiences and psychiatric problems in a cohort of incarcerated females and males. A psychiatric background, childhood trauma characterized by sexual abuse and violent crimes were found to be predominant in female prison inmates, whereas a criminal background with a younger age at first offense and frequent previous convictions, substance use and sexual crimes were more prevalent among male prison inmates. Our findings indicate a potential link between childhood traumatization and criminal behavior in terms of subsequent offending but not in terms of severity of the subsequent offense.

Amniotic fluid oxidant-antioxidant status in foetal congenital nervous system anomalies.

Objective This study aimed to evaluate the oxidant-antioxidant status of amniotic fluid in pregnant women with foetal congenital malformations of the central nervous system. Methods We studied pregnant women with foetal congenital nervous system anomalies at 16-22 weeks' gestation (n = 36). The control group (n = 30) consisted of pregnant women at the same gestational age who underwent amniocentesis, resulting in a normal karyotype. We analysed glutathione, catalase, and malondialdehyde levels in amniotic fluid. Enzyme activation was measured by spectrophotometry. Results The demographic features of the groups were similar in terms of age, parity, body mass index, and gestational weeks. We detected lower glutathione and catalase levels in the foetal congenital anomaly group than in the control group. We detected higher malondialdehyde levels in the foetal congenital anomaly group than in the control group. Conclusion In the organism, the rate of formation of free radicals and their rate of removal are balanced, and this is called oxidative balance. As long as oxidative stability is achieved, the organism is not affected by free radicals. This fact should be kept in mind to avoid any type of teratogenic agent that could lead to congenital disorders.

Levels of nitric oxide, asymmetric dimethyl arginine, symmetric dimethyl arginine,and L-arginine in patients with obsessive-compulsive disorder.

BACKGROUND/AIM: We aimed to investigate and compare to healthy controls the variations in the levels of nitric oxide (NO), asymmetric dimethyl arginine (ADMA), symmetric dimethyl arginine (SDMA), and L-arginine levels in patients with obsessive-compulsive disorder (OCD). MATERIALS AND METHODS: We enrolled 30 patients with OCD and 30 healthy controls in the study consecutively. Diagnostic interviews of all participants were conducted with the Structured Clinical Interview for Axis I Disorders (SCID-I), and sociodemographic data of the participants were recorded. Patients scoring 10 points or more on the Yale-Brown Obsessive-Compulsive Scale were enrolled in the study. RESULTS: The NO levels of patients with OCD were increased compared to the control group, but the increase was not statistically significant (P > 0.05). However, patients with OCD had significantly lower levels of ADMA, SDMA, and L-arginine compared with the controls (P < 0.001). CONCLUSION: We found a significant decrease in ADMA, SDMA, and L-arginine as NO inhibitors between the groups, possibly because of an increase in NO. However, the insignificant increase in NO suggests that ADMA, SDMA, and L-arginine play direct and potentially important roles in OCD biology.

Electroacupuncture Therapy in Nicotine Dependence: A Double Blind, Sham-Controlled Study.

INTRODUCTION: The number of non-pharmacological controlled studies is insufficient in the treatment of nicotine dependence (ND). Nevertheless, non-pharmacological treatments, such as electroacupuncture (EA), are becoming increasingly popular in the treatment of ND. The aims of this study were to determine the efficacy and safety of "true EA therapy" (TEAT) compared to those of "sham EA therapy" (SEAT) in ND treatment. METHODS: Eligible patients who met the DSM-IV criteria for ND (n=450) were included in the study. This study was a double-blinded, sham-controlled clinical trial with a 4-week treatment period and 4-week follow-up conducted between June and December 2009 at a psychiatry outpatient clinic. One hundred and sixty four adult (≥18 years; 44 men, 120 women) cigarette smokers out of 450 patients who met the inclusion and exclusion criteria were enrolled in the study in a ratio of 1:1 to receive TEAT (n=84) or SEAT (n=80). Routine biochemical and hematological tests, chest X-Ray, and ECG were carried out; end-expired carbon monoxide (CO) levels were measured too. Clinical characteristics were obtained through the Fagerström Nicotine Dependence Test (FNDT), Hamilton Rating Scale for Depression (HRSD), and Hamilton Anxiety Scale (HAS). EA was carried out by a trademark device, Antismoke 3000®. Efficacy analyses were performed on "intent-to-treat analysis." Primary outcome was the differences from baseline to endpoint in mean FNDT, number of cigarettes smoked per day, and CO levels at week 4. Secondary outcomes were the same variables at week 8. These variables were assessed via analysis of covariance (ANCOVA). RESULTS: Mean baseline FNDT, HRSD, HAS, and CO levels of the groups were statistically similar. TEAT and SEAT groups demonstrated no significant changes in the outcome variables and smoking cessation rates (35.7% and 30%, respectively). Of those remaining outside of the study, 8.3% were from the TEAT group and 8.7% were from the SEAT group; there was no statistical difference between the groups. The rate of treatment discontinuation was similar between the TEAT (44%) and SEAT (43.7%) groups (p>0.05). The rates of adverse events were not similar too. CONCLUSION: This study showed that both TEAT and SEAT have similar efficacy and safety profiles in patients with ND.

Effects of paliperidone extended release on functioning level and symptoms of patients with recent onset schizophrenia: An open-label, single-arm, flexible-dose, 12-months follow-up study.

BACKGROUND: Response to antipsychotic treatment is better in the early stages of schizophrenia. AIMS: The primary objective of this non-randomized, single-arm, multicenter clinical trial was to explore the response to treatment and safety of a flexible dose of paliperidone (mean = 6.42 mg/day) in patients with recent onset schizophrenia (< 3 years after the first episode/hospitalization). METHODS: Severity of clinical symptoms was evaluated by the Positive and Negative Syndrome Scale (PANSS), functioning was assessed using the Global Assessment of Functioning (GAF) scale and the Personal and Social Performance Scale (PSP). RESULTS: In a total of 85 patients enrolled, 80 patients were eligible. Total PSP score at baseline (50.2 ± 11.6) increased at all visits. Total PSP score was 65.4 ± 12.1 at month 12 (P < 0.001). GAF scores were significantly higher at all visits compared with baseline (P = 0.001). It was 62.4 ± 12.5 with an increase of 42.9% at month 12 (P < 0.001). PANSS Positive and Negative subscales and General psychopathology subscale scores showed significant reductions beginning with month 3 and were 11.9 ± 3.8 (29.3%; P < 0.001), 13.7 ± 5.6 (27.3% P < 0.001) and 27.8 ± 7.1 (23.2%; P < 0.001) at month 12, respectively. Twelve patients (14.3%) had a serious adverse event. The most common adverse events were insomnia (17.9%), nausea (8.3%), akathisia (4.8%), anxiety (4.8%) and depression (4.8%). Body weight values at the end of the study were significantly higher compared with baseline. CONCLUSION: The present study demonstrates that flexible dose of paliperidone resulted in a significant improvement in functioning and reduction in symptoms in patients with recent onset schizophrenia.

Electroencephalography Spectral Power Density in First-Episode Mania: A Comparative Study with Subsequent Remission Period.

INTRODUCTION: Our aim in this study was to investigate spectral power density (PSD) in first-episode mania and subsequent remission period and to evaluate their difference. METHODS: Sixty-nine consecutive cases referring to our hospital within the previous 1 year, who were evaluated as bipolar disorder manic episode according to The Diagnostic and Statistical Manual of Mental Disorders-IV (DSM-IV) at the first episode and had the informed consent form signed by first degree relatives, were included in this study. Exclusion criteria included having previous depressive episode, using drugs which could influence electroencephalographic activity before electroencephalography (EEG), and having previous neurological disease, particularly epilepsy, head trauma, and/or loss of consciousness. EEG records were obtained using a digital device in 16 channels; 23 surface electrodes were placed according to the International 10-20 system. Spectral power density (dbµV/Hz) of EEG signal provided information on the power carried out by EEG waves in defined frequancy range per unit frequency in the present study. RESULTS: A peak power value detected on the right with FP2P4 and on the left with F7T3 electrodes were found to be higher in the manic episode than in the remission period (p=0.018 and 0.025). In the remission period, in cases with psychotic symptoms during the manic period, F4C4 peak power value was found to be lower than that in cases with no psychotic findings during the manic period (p=0.027). There was no relation was found between YMRS scores and peak power scores. CONCLUSION: Electrophysiological corollary of mood episode is present from the onset of the disease, and it differs between the manic and remission periods of bipolar disorder. In the remission period, peak power values of PSD distinguish cases with psychotic findings from cases without psychotic findings when they were manic.

[ADHD in adult psychiatric outpatients: prevalence and comorbidity]. / Ayaktan psikiyatri hastalarinda dikkat eksikligi ve hiperaktivite bozuklugu: yayginlik ve estanilar.

AIM: This study aimed to investigate the prevalence of attention-deficit/hyperactivity disorder (ADHD) in adult psychiatric outpatients. Moreover, comorbid psychiatric diagnoses in adults with ADHD were determined. Patients with and without ADHD were compared regarding DSM Axis I-II comorbidity and sociodemographic characteristics. MATERIALS AND METHODS: The study included patients that presented for the first time to a psychiatric outpatient clinic during a 3-month period and were evaluated for adult ADHD. A sociodemographic form, Wender Utah Rating Scale, Turgay's Adult ADD/ADHD Evaluation Scale, Structured Clinical Interview I and II, Symptom Check List-90-R, and Beck Depression Inventory were administered. RESULTS: The study included 246 patients. Among the 39 patients diagnosed with ADHD, 25 were female (64.1%) and 14 were male (35.9%), and the mean age was 27.38 ± 8.3 years. The prevalence of ADHD in adult psychiatric patients was 15.9%. Adults with ADHD usually presented due to comorbid psychiatric problems; major depression (43%), generalized anxiety disorder (23%), and obsessive-compulsive disorder (17%) were the most common comorbid diagnoses. Substance abuse (58.9%) and attempted suicide (38.5%) were among the most prevalent psychiatric problems. CONCLUSION: The present findings show that ADHD is an important comorbidity in adult patients that present to psychiatric clinics, and may cause serious mental health problems or complicate mental illness.

Extraordinary cause of complete colonic obstruction in children: urinary retention.

Complete colonic obstruction in children may occur secondary to congenital, and acquired factors related to the gastrointestinal system. Herein, we report an extraordinary presentation of complete colonic obstruction due to extensive urinary retention in a 3-year-old boy. The possible underlying mechanism was detected as urinary infection in a child with horseshoe kidney. The treatment of the bladder symptoms and urinary infection relieved the obstruction of the colon. To our knowledge, especially in children, colonic obstruction due to urinary retention has not been reported in the literature.

Clinical, psychological and maternal characteristics in early functional constipation.

BACKGROUND: This cross-sectional study investigated the clinical features of functional constipation (FC) at preschool age, as well as emotional and behavioral characteristics of the children, psychological symptom level and parental attitudes of the mothers, and compared these with that of non-referred typically developing controls with normal intestinal habits. METHODS: Participants included 65 children with FC (mean age, 43.6 ± 15.4 months; range, 25-72 months), 59 healthy controls (mean age, 46.9 ± 14.5 months; range, 25-72 months) and the mothers of the children. The Childhood Behavior Checklist, Symptom Checklist 90 and Parental Attitude Research Instrument were filled in by the mothers. RESULTS: Participants with FC had higher problem scores than the comparison children in a variety of emotional and behavioral parameters. Approximately half exhibited internalizing and one-third had externalizing problems in the clinical range. The mothers of the patient group had higher levels of psychological distress, overprotective parenting and strict discipline. On multiple logistic regression analysis child psychopathology, maternal education level and maternal distress were independently associated with FC. CONCLUSION: Behavior problems are common in children with FC from an early age. Low level of education and high psychological distress of the mothers seem to be important risk factors for constipation and should be assessed carefully in the management of these cases.

Comparison of Sexual Function and Hormonal Parameters Between Mood Stabilizer Treatment Modalities in Bipolar Disorder.

INTRODUCTION: The aim of this study was to determine the differences between lithium and atypical antipsychotics (quetiapine and olanzapine) with regard to their effects on sexual functions and hormonal variables and to assess the findings in term of gender differences, in patients with bipolar disorder. METHOD: 28 female and 29 male patients diagnosed as having bipolar disorder type I according to the DSM-IV, using lithium or quetiapine and quetiapine+lithium or olanzapine and olanzapine+lithium were evaluated consecutively. Being in remission period and given informed consent were set as inclusion criteria in these cases. Interviews with the patients were carried out using the Structured Clinical Interview for DSM-IV Axis I Disorders (SCID-I) and SKIP-TURK. Sexual functions and satisfaction were evaluated with the Arizona Sexual Experiences Scale (ASEX) and the Golombok Rust Inventory of Sexual Satisfaction (GRISS). Blood samples of the patients were taken in order to determine prolactin (PRL), follicle-stimulating hormone (FSH), luteinizing hormone (LH), estradiol (E2), and free testosterone (T) levels. RESULTS: GRISS scores in male patients were higher than in female patients (p=.001). The number of manic, depressive and total episodes, and functionality levels were similar between the treatment groups, both in female and male patients. No differences were found between treatment modalities in terms of hormone levels both in female and male patients. Among females, ASEX scores of the patients treated with lithium monotherapy were less than the ones treated with quetiapine and olanzapine. Among patients with quetiapine monotherapy, GRISS scores in male patients were higher than in female patients. CONCLUSION: There are some evidences showing gender-based differences in the side effects of atypical antipsychotic drugs. Future studies with a specific focus on this topic are needed in order to have a better understanding of the basic mechanisms of gender differences.

Rare case of an abdominal mass presenting as acute abdomen: torsion of the vermiform appendix.

Torsion of the vermiform appendix is a rarely observed acute abdominal emergency. The clinical manifestations are similar to acute appendicitis. It should be included in the differential diagnosis if a patient presents with intermittent abdominal pain and an acute abdominal emergency. Here, we describe a 4-year-old male patient with a mass located in the right lower abdominal quadrant, whose clinical findings were consistent with an acute abdomen. The gangrenous appendix was found in the pelvic cavity and its stump was twisted clockwise. A 1.5-cm fecalith was detected in the appendix lumen and appendectomy was performed.

Clinical, Neurocognitive, Structural Imaging and Dermatogliphics in Schizophrenia According to Kraepelin Criteria.

INTRODUCTION: A century ago, Kraepelin stated that the distinctive feature of schizophrenia was progressive deterioration. Kraepelin criteria for schizophrenia are: (1) continuous hospitalization or complete dependence on others for obtaining basic necessities of life, (2) unemployment and (3) no remission for the past five years. We aimed to determine the clinical appearance and structural biological features of Kraepelinian schizophrenia. METHODS: The sample consisted of 17 Kraepelinian patients, 30 non-Kraepelinian schizophrenic patients and 43 healthy controls. The Clinical Global Impressions (CGI) and the Positive and Negative Syndrome Scales (PANSS) were used for clinical assessment. The Frontal Assessment Battery (FAB) and the Verbal Fluency and Color Trail Test (CTT) were included in the cognitive battery. Brain magnetic resonance imaging and dermatoglyphic measurements were performed for structural features. RESULT: Duration of illness, hospitalization, suicide attempts, admission type, presence of a stressor and treatment choice were similar between the two patient groups. Treatment resistance and family history of schizophrenia were more common in Kraepelinian patients. PANSS and CGI subscales scores were also higher in this group. Only the category fluency and CTT-I were different in Kraepelinian patients in comparison to the other patient group. Structural findings were not different between the three groups. CONCLUSION: Category fluency, which was lower in Kraepelinian patients, is an important marker of a degenerative process. The collection of severe clinical symptoms, family history of psychiatric illness and nonresponse to treatment in this particular group of patients points to the need to conduct further studies including cluster analysis in methodology.

Stupor due to possible interaction between Lorazepam and valproic acid: report of two cases.

Valproate (VPA) and lorazepam are excreted mainly by glucuronide conjugation. VPA reduces the excretion of lorazepam as a result of the administration of these two medications together. As a result of these interactions, even if rarely, serious adverse effects such as coma may develop. Herein, we present two cases of stupor which developed after the addition of lorazepam to treatment administered with VPA. The first patient was being followed for five years with a diagnosis of schizoaffective disorder. She was subjected to a treatment of VPA at 1000 mg/day and an antipsychotic drug. On the twentieth day of the treatment, Lorazepam 2.5 mg was administered as an anxiolytic. The second patient was being followed with a diagnosis of schizophrenia for nine years. A VPA treatment of 750 mg/day was initiated together with an antipsychotic treatment. On the eighth day of the treatment, Lorazepam 2.5 mg was administered. A few hours later, a stupor manifestation developed in both of the patients. Administration of the entire medication to the patients was terminated and parenteral liquid administration was initiated. The clinical profile was back to normal approximately 24-36 hours following the termination of the medication. Studies about the clinical reflections of the VPA and Lorazepam interaction are limited. However, it must be remembered that as a result of the interaction of these two medications, conditions that vary between stupor and coma may arise.

Low plasma adiponectin levels in panic disorder.

BACKGROUND: The present study was performed to evaluate plasma adiponectin levels in the patients with PD. METHOD: The study group included a total of 28 patients (17 females, 11 males) and 23 age- and sex-matched healthy comparison subjects (10 females and 13 males). The plasma fasting glucose, total cholesterol, triglyceride, low density lipoprotein (LDL), high density lipoprotein (HDL), and hemoglobin were measured. RESULTS: There were no differences in regard to plasma fasting glucose, total cholesterol, triglyceride, LDL, HDL, and hemoglobin levels between groups. However, the mean adiponectin levels were significantly lower in the patient group (26.96 ± 9.92 ng/ml) compared to controls (37.63 ± 23.17 ng/ml) (t=-2.21; p=0.032). As for the ANCOVA analyses, it revealed the main effect of diagnosis on adiponectin levels (F=5.78, p=0.020) after BMI (body mass index) and gender as covariates. CONCLUSIONS: Consequently, the findings of our study suggest that there may be an interaction between panic disorder and plasma adiponectin. Moreover, they led us to consider that these patients should be also followed as cardiac problems.
