Pain in somatoform disorders: is somatoform pain disorder a valid diagnosis?

OBJECTIVE: Investigate the validity of DSM-IIIR somatoform pain disorder (SPD) by comparing subgroups of somatoform disorder patients on several measures of psychopathology. METHOD: A total of 144 patients with unexplained physical symptoms were referred from non-psychiatric departments. Among these, 127 patients with somatoform disorders were identified, classified according to the Structured Clinical Interview for DSM (SCID) diagnostic interview, and rated with scales for somatization, anxiety, depression and personality traits. RESULTS: Patients presenting pain did not differ significantly from patients presenting non-pain symptoms on measures of symptoms and personality traits. Correspondingly, patients with SPD did not differ significantly from patients with conversion disorder (CD), while patients with Somatization disorder (SD) had higher scores on most scales for psychopathology and personality disorder. CONCLUSION: Significant diagnostic and symptomatic overlap was found between SPD and CD, and although the statistical power of the study was modest, the study questions the validity of the current definition of SPD.

[Differences between female and male patients with eating disorders--results of a multicenter study on eating disorders (MZ-Ess)].

Publications about men with eating disorders are still rare. Therefore, in view of the current status of the findings, it seems worthwhile to examine the differences that are empirically verified as well as the relevant common features between the sexes. Based on a representative sample, therefore, male and female patients with eating disorders in inpatient treatment are compared in terms of demographic and clinical variables (symptoms and personality), both at the beginning of treatment and two-and-a-half years after the inpatient treatment, and the findings are discussed with regard to their "gender specificity". The study covered 1,171 patients (male and female) with the diagnosis criteria for anorexia, bulimia and double diagnosis according to DSM-III-R; 33 of them were men. Anorexia cases (342 women and 13 men) and bulimia cases (629 women and 18 men) were compared at the beginning of treatment with the following instruments: Symptom Checklist 90-R; Eating Disorder Inventory; questionnaire for the symptom diagnosis of eating disorders; Freiburger Persönlichkeitsinventar and Narzissmus-Inventar. As a measure of success in the 2.5 year catamnesis (764 women and 20 men), operationalized criteria were defined using the LIFE. The 2.8 % share of men with eating disorders in inpatient treatment again confirms the special nature of this clinical disorder for men. An interesting result is the later onset of illness in male anorexia cases. Coinciding with comparable studies, there are only minor differences in eating behavior, but the differences in body experience are much more pronounced. In bulimic men, there is a higher percentage of homosexuals and they are more satisfied with their body. Anorectic men have a greater gain from the illness, are more concerned about their health and are less performance-minded than female anorectics. The differences that were found clearly indicate that these occur especially in the area of dealing with the body and the significance of the body. One of the reasons why the results in the area of personality and sexual identity are interesting is that they point to differences which definitely appear to be significant, not just between the sexes, but also between male anorexia and bulimia.

[Sleep-related breathing disorders--a second edition of the International Classification of Sleep Disorders (ICSD-2) of the American Academy of Sleep Medicine (AASM)].

In 2005 the American Academy of Sleep Medicine (AASM) published a revised form of the International Classification of Sleep Disorders (ICSD-2). Goals of the ICSD-2 are: A) To describe all currently recognized sleep and arousal disorders, and to base the descriptions on scientific and clinical evidence. B) To present the sleep and arousal disorders in an overall structure that is rational and scientifically valid. C) To render the sleep and arousal disorders as compatible with ICD-9 and ICD-10 as possible. In this article, sleep-disordered breathing disorders, as classified in the ICSD-2 are presented.

Practice parameters for the use of actigraphy in the clinical assessment of sleep disorders. American Sleep Disorders Association.

These clinical guidelines, which have been reviewed and approved by the Board of Directors of the American Sleep Disorders Association, provide recommendations for the practice of sleep medicine in North America for the use of actigraphy in the clinical assessment of sleep disorders. The American Sleep Disorders Association has produced these guidelines, based upon a critical review of the scientific literature, regarding the use of actigraphy in the clinical evaluation of sleep disorders. Though not indicated for the routine assessment of sleep disorders, actigraphy may be a useful adjunct, in certain circumstances, to a detailed history and examination when demonstration of multiday rest-activity patterns is necessary to diagnose, document severity, and guide proper treatment of sleep disorders.

Comparison of clonidine response in the treatment of attention-deficit hyperactivity disorder with and without comorbid tic disorders.

OBJECTIVE: Clonidine has been suggested as an alternative pharmacotherapy for patients with attention-deficit hyperactivity disorder (ADHD) and comorbid tic disorders. To examine the efficacy of clonidine in this population of children, the use of clonidine in the treatment of children with ADHD with and without comorbid tic disorders was examined in a retrospective chart review of 54 children over a 4-year period. METHOD: Treatment was administered openly to these patients in a Pediatric Psychopharmacology Clinic, and response was assessed using clinical global improvement measures. RESULTS: Clonidine treatment resulted in improvement in both the ADHD (39/54; 72%) and tic symptoms (18/24; 75%) groups. The findings suggested that the children with ADHD with comorbid tic disorders (23/24; 96%) have a more frequent positive behavioral response to clonidine than children with ADHD without comorbid tic disorders (16/30; 53%). CONCLUSIONS: This report provides further support of a role for clonidine in the treatment of children with ADHD, particularly for those with comorbid tic disorders.

Prediction of adolescent affective disorder: effects of prior parental affective disorders and child psychopathology.

OBJECTIVE: To examine the role of major parental and child diagnostic factors in predicting episodes of serious affective disorder in adolescents in a nonreferred sample. METHOD: The sample included 139 youngsters (average age 14 years at enrollment) drawn from a health maintenance organization and evaluated at two points in time 4 years apart. Both parents and adolescents were assessed using structured diagnostic instruments scored according to criterion systems. Parent and child lifetime diagnoses identified in the first assessment were used to predict the onset of episodes of serious affective disorder in the adolescents which occurred between the first and second assessment. RESULTS: Stepwise multiple regression analyses of the significant univariate factors showed that the most powerful predictors of episodes of affective disorder were total number of diagnoses the adolescents received prior to first assessment, lifetime duration of parental major depressive disorder, and total number of lifetime nonaffective disorders of the parents. CONCLUSION: Broad risk factors from different domains best predict episodes of affective disorder in children and adolescents.

Learning disorders with a special emphasis on reading disorders: a review of the past 10 years.

OBJECTIVE: To review the past 10 years of clinical and research reports on learning disorders. METHOD: The most common and best-researched type of learning disorder is reading disability, which is the focus of this review. A selective review of the literature from Psychological Abstracts and Index Medicus from 1985 to the present was conducted. This review focused on conceptual and methodological issues, current assessment practices, epidemiology, correlates of brain function, biological factors, predictors of reading achievement, core deficits, comorbidity reading development and instructional approaches, treatment, and outcome. RESULTS: Definitional issues, still unresolved, bedevil the field with the debate between those for and those against discrepancy definitions of reading disabilities. Nevertheless considerable progress has been made. Phonological processing problems are now considered the main core deficit responsible for reading disabilities. Correlates of brain function and possible genetic factors are noted. Comorbidity with externalizing and internalizing disorders is described, and some theories for the overlap are identified. Studies on the comorbidity with internalizing disorders are lacking. Good assessment practice and promising approaches to remediation are identified. Unless a concurrent disorder is present, the use of medication for the treatment of reading disabilities should be considered experimental. Favorable outcomes are dependent on initial severity and a supportive home and school environment. CONCLUSIONS: Much progress has been made in our understanding of learning disabilities, especially in reading disabilities. Resolution of definitional and conceptual issues will greatly assist research into assessment, treatment, and long-term outcome of learning disabilities with and without concurrent psychiatric disorders. Further research into the nature, extent, and correlates of comorbid learning disabilities and their treatment is much needed.

The eight-item treatment-outcome post-traumatic stress disorder scale: a brief measure to assess treatment outcome in post-traumatic stress disorder.

This preliminary report describes a new brief interview based assessment of post-traumatic stress disorder using an 8-item treatment-outcome post-traumatic stress disorder scale (TOP-8). The TOP-8 was developed from a larger post-traumatic stress disorder evaluation scale based on items which occurred frequently in the population and which responded substantially to treatment across time. The 8 resultant items were drawn from all three symptom clusters for post-traumatic stress disorder, and showed an improved ability to detect drug versus placebo differences in comparison with the original scale. The eight-item treatment-outcome post-traumatic stress disorder scale also correlated significantly with a self-rated measure of post-traumatic stress disorder and distinguished at a highly significant level between responders and non-responders on an independently judged Clinical Global Impressions measure. The results of this study are discussed and future directions suggested.

Panic, agoraphobia, and panic disorder with agoraphobia. Data from a multicenter anxiety disorders study.

In a cross-sectional investigation of the properties of DSM-III-R panic disorder (PD), panic disorder with agoraphobia (PDA), and agoraphobia without history of panic disorder (AWOPD), we analyzed demographic, descriptive, comorbidity, treatment, and course data for 562 subjects with PD, PDA, or AWOPD in a multicenter anxiety-disorders study. In general, AWOPD subjects had the worst functioning and PD subjects the best, as measured by length of intake episodes, education attained, likelihood of receiving financial assistance, depressive comorbidity, and likelihood of having experienced 8 weeks symptom-free. Panic disorder with agoraphobia was the most common disorder and emerged as a condition intermediate in severity between the other two. Treatments received varied little by diagnosis. Most subjects received medication, usually benzodiazepines. Psychodynamic psychotherapy was the most frequently received psychosocial treatment; cognitive and behavioral approaches were less common. Subjects classified with AWOPD were the most likely to have received exposure therapies.

Borderline personality disorder and perceived family dysfunction in the eating disorders.

Borderline personality disorder is associated with anorexic and bulimic disorders, but the factors that underlie that association are not understood. This study of a case series of eating disordered women investigates the potential role of perceived family dysfunction as one critical explanatory factor. The syndrome and symptoms of borderline personality disorder are associated with specific features of perceived family interaction. Possible causal mechanisms are proposed to explain the links among family dysfunction, borderline personality disorder, and the eating disorders, although further research is needed to test these models. The clinical implications of these findings are discussed.

Peroxisomal disorders I: biochemistry and genetics of peroxisome biogenesis disorders.

The peroxisomal disorders represent a group of genetic diseases in humans in which there is an impairment in one or more peroxisomal functions. The peroxisomal disorders are usually subdivided into two subgroups including (i) the peroxisome biogenesis disorders (PBDs) and (ii) the single peroxisomal (enzyme-) protein deficiencies. The PBD group is comprised of four different disorders including Zellweger syndrome (ZS), neonatal adrenoleukodystrophy (NALD), infantile Refsum's disease (IRD), and rhizomelic chondrodysplasia punctata (RCDP). ZS, NALD, and IRD are clearly distinct from RCDP and are usually referred to as the Zellweger spectrum with ZS being the most severe and NALD and IRD the less severe disorders. Studies in the late 1980s had already shown that the PBD group is genetically heterogeneous with at least 12 distinct genetic groups as concluded from complementation studies. Thanks to the much improved knowledge about peroxisome biogenesis notably in yeasts and the successful extrapolation of this knowledge to humans, the genes responsible for all these complementation groups have been identified making molecular diagnosis of PBD patients feasible now. It is the purpose of this review to describe the current stage of knowledge about the clinical, biochemical, cellular, and molecular aspects of PBDs, and to provide guidelines for the post- and prenatal diagnosis of PBDs. Less progress has been made with respect to the pathophysiology and therapy of PBDs. The increasing availability of mouse models for these disorders is a major step forward in this respect.

Epidemiology of neonatal acute respiratory disorders. A multicenter study on incidence and fatality rates of neonatal acute respiratory disorders according to gestational age, maternal age, pregnancy complications and type of delivery. Italian Group of Neonatal Pneumology.

A prospective 3-month survey of neonatal respiratory disorders in 17,192 Italian infants born in 65 hospitals, located in 17 Italian regions representative of northern, central and southern Italy, was performed to evaluate the incidence of neonatal acute respiratory disorders and their risk factors. The prematurity rate was 7.3%, while the extremely low birth weight (< 1,000 g) and very low birth weight (< 1,500 g) rates were 0.58% and 0.99%, respectively. Four hundred and ninety-one infants (2.8%) developed respiratory signs. Lethality or specific fatality rate (SFR) for acute respiratory disorders with regard to the overall study population was 0.45%. The male/female ratio of affected infants was 1.3:1. Among affected newborns the case fatality rate (CFR) for respiratory disorders was 15.88% (78/491) and was higher in males than in females (2:1), in infants with a gestational age of < or = 28 weeks (60%) and birth weights of < 1,000 g (50%). Moreover, the SFR was higher (p < 0.05) in the infants of mothers older than 34 years. SFR was 3.0% in intrauterine growth-retarded infants, 3.6% in the first twin and 3.2% in the second twin. An Apgar score of < or = 3 at 5 min was strongly related to the incidence of respiratory disorders (47.1%). The antenatal prevention of neonatal respiratory distress syndrome with maternal corticosteroid treatment was performed in 84% of newborns (< 32 weeks) with respiratory problems in northern Italy, and about 25% and 38% in central and southern Italy, respectively. The CFR was double in southern Italy as compared with northern and central Italy. Prematurity, low birth weight and a low Apgar score (< or = 3) at 1 and 5 min as well as a maternal age of > 34 years are risk factors for acute respiratory disorders.

Family history of panic disorder and hypersensitivity to CO2 in patients with panic disorder.

OBJECTIVE: The authors investigated the relationships between hypersensitivity to CO2 and familial-genetic risk for panic disorder in patients with panic disorder. METHOD: Morbidity risks for panic disorder were calculated for families of 203 patients with panic disorder, each of whom was challenged with 35% CO2. RESULTS: Patients who reacted with a positive response to the 35% CO2 challenge showed a genetic risk for panic disorder (morbidity risk = 14.4%) that was significantly higher than that for patients who did not react (morbidity risk = 3.9%). CONCLUSIONS: These findings support the idea that hypersensitivity to CO2 might be associated with a subtype of panic disorder specifically related to a greater familial loading.

Identification of the Slynar gene (AY070435) and related brain expressed sequences as a candidate gene for susceptibility to affective disorders through allelic and haplotypic association with bipolar disorder on chromosome 12q24.

OBJECTIVE: Three linkage studies of bipolar disorder have implicated chromosome 12q24.3, with significant lod scores of over 3.00. Several other linkage studies have found lod scores between 2.00 and 3.00. In order to identify which gene on this chromosome is responsible, the authors carried out tests of allelic association with bipolar disorder in order to fine map an affective disorder susceptibility gene. METHOD: DNA samples from 681 bipolar disorder patients and 570 comparison subjects from Denmark and the United Kingdom were genotyped with markers close to the region at which the authors had found maximum linkage in previous studies. RESULTS: Single marker allelic association was found with four markers in the Danish cohort. Seven markers in exactly the same region were then found to show significant allelic association in the U.K. cohort. Tests of haplotypic association were also significant, confirming the single marker allelic associations. CONCLUSIONS: These positive fine mapping results validate earlier linkage studies and implicate a 278-kilobase region of chromosome 12 that contributes to the etiology of bipolar disorder. Several brain transcripts are transcribed from sequences in the region. The main candidate gene has no known function but is found in human brain cDNA and is homologous to a Macaque brain cDNA. Sequencing of expressed sequences and control regions in the area should identify etiological base pair changes that increase susceptibility to bipolar disorder.

SSRI treatment of borderline personality disorder: a randomized, placebo-controlled clinical trial for female patients with borderline personality disorder.

OBJECTIVE: Selective serotonin reuptake inhibitors (SSRIs) are recommended for treatment of affect lability, impulsivity, and aggression in patients with borderline personality disorder. This recommendation is based on positive findings in at least 10 open studies and one small double-blind study of SSRIs for patients with borderline personality disorder and one study of impulsive aggressive patients with different personality disorders. A randomized, placebo-controlled SSRI study with borderline personality disorder patients, however, provided inconclusive results because of a large response to placebo. It was, therefore, decided to conduct a new randomized trial with a larger study group. METHOD: A double-blind, placebo-controlled, randomized trial using the SSRI fluvoxamine for 6 weeks followed by a blind half-crossover for 6 weeks and an open follow-up for another 12 weeks was conducted with 38 nonschizophrenic, nonbipolar female patients with borderline personality disorder. The outcome measures were the rapid mood shift, impulsivity, and aggression subscales from the Borderline Personality Disorder Severity Index. RESULTS: Fluvoxamine but not placebo produced a robust and long-lasting reduction in the scores on the subscale for rapid mood shifts. In contrast, no difference between the fluvoxamine and placebo groups was observed in the effect on the impulsivity and aggression scores. CONCLUSIONS: In this study, fluvoxamine significantly improved rapid mood shifts in female borderline patients, but not impulsivity and aggression. This latter finding may be due to gender-specific differences in impulsivity and aggression.

Dysthymic disorder and rheumatic pain modulation disorder (fibrositis syndrome): a comparison of symptoms and sleep physiology.

It has been suggested that "fibrositis" or rheumatic pain modulation disorder (RPMD) is a variant of depressive illness. Both disorders are associated with abnormalities in sleep physiology. Since the clinical features of RPMD do not meet all the criteria for a major depressive disorder, the symptoms and sleep physiology in subjects with dysthmic disorder (DSM III criteria) (N = 6), and RMPD (N = 6) were compared, in order to determine the similarity between the two groups. The sleep physiology in dysthymic disorder was first examined over three consecutive nights since a systematic evaluation of the sleep physiology in this group of disorders has not yet been reported. All dysthymic patients showed episodic bursts of high-amplitude (75-150 microvolts) theta (3-5 Hz) bursts in stage 2 sleep, and REM onset latency was abbreviated only on night 2. The theta bursts have not been previously reported, and may be an early marker of disorganization of non-REM sleep in the dysthymic subjects. The comparison of the two groups revealed that RPMD subjects reported more pre- and post-sleep pain (p less than 0.01), lighter sleep (p less than 0.01), and more physical ailments during sleep (p less than 0.01), and had more alpha (7-11.5 Hz) in non-REM sleep (p less than 0.01).(ABSTRACT TRUNCATED AT 250 WORDS)

Influence of psychiatric disorder on the controlling behaviour of mothers with 1-year-old infants. A study of women with maternal eating disorder, postnatal depression and a healthy comparison group.

BACKGROUND: Certain styles of parental controlling behaviour influence child development. Work with mothers with eating disorders suggests that they may be particularly controlling of their infants. AIMS: To examine the nature and specificity of maternal controlling behaviour in mothers with eating disorders compared with mothers who had experienced postnatal depression and a healthy comparison group. METHOD: Mothers with eating disorders (n=34), postnatal depression (n=39) and a healthy comparison group (n=61) and their 12-month-old infants were observed during play and mealtimes, and blind ratings made of verbal and non-verbal control exerted by the mother. RESULTS: Mothers in the eating disorder group used more verbal control, especially strong control. There were no differences between the groups on gentle verbal control and physical contact. Maternal dietary restraint was the one feature of eating disorder psychopathology associated with the use of verbal control. Marital criticism was also associated with the extent of verbal controlling behaviour. CONCLUSIONS: Aspects of maternal control of infants were found to be specific to maternal eating disorder psychopathology.

[Association between dopamine beta hydroxylase gene and attention deficit hyperactivity disorder complicated with disruptive behavior disorder].

OBJECTIVE: Attention deficit hyperactivity disorder (ADHD), a common behavior disorder of childhood, is a highly heterogeneous disease frequently accompanied by various mental disorders, including disruptive behavior disorder (DBD). Studies show that children suffering from ADHD with DBD are at higher risk of antisocial personality, substance abuse, and social adaptations disorder at their adulthood. The dopamine beta hydroxylase (DbetaH) is the key enzyme to ADHD since it catalyzes the conversion of dopamine to norepinephrine, and dysfunction there of is believed to be one of the causes of the disorder. To explore the association between DBH gene and ADHD complicated with or without DBD, the authors analyzed the transmission of a novel polymorphism DBH -1021C-->T, which is found associated with plasma DbetaH activity, in ADHD nuclear families using transmission disequilibrium test (TDT). METHODS: Consensus diagnoses were based on the DSM-IV. The samples included those from 292 Chinese Han nuclear families with ADHD probands. Genotypes of DBH -1021C-->T polymorphism were determined by PCR amplification, endonuclease digesting and electrophoresis. The transmission of DBH -1021C-->T polymorphism in ADHD nuclear families with or without DBD was analyzed by TDT. RESULTS: The results showed that there was transmission disequilibrium between DBH-1021C-->T polymorphism and ADHD with or without DBD. In ADHD comorbid with DBD, T allele was preferentially transmitted (P < 0.05); and in ADHD without DBD, so was the C allele (P < 0.05). Among the three subtypes of ADHD, only ADHD-C subtype with DBD had an increased transmission of T allele (P < 0.05). CONCLUSION: There is an association between DBH gene and ADHD comorbid with or without DBD, but the preferential transmission alleles are different. The low activity T allele is increased to transmit in ADHD with DBD, while the high activity C allele is preferentially transmitted in ADHD without DBD. The results support the proposition that the genetic mechanism is different between ADHD comorbid with or without DBD. We also found that only ADHD-C subtype with DBD is associated with DBH -1021C-->T polymorphism in three subtypes of ADHD, which may suggest that there is a more intense relationship between DBD and ADHD-C subtype.
