Eating disorder in a patient with phenotypical features of Lujan-Fryns syndrome.
We report a young patient with phenotypic, cognitive and behavioural features consistent with a diagnosis of Lujan-Fryns syndrome. He exhibited a severe eating disorder with food refusal and psychogenic loss of appetite, which led to a serious state of malnutrition. Behavioural difficulties including shyness, hyperactivity and emotional instability are present in almost 80% of the described patients with Lujan-Fryns syndrome but eating disorders have not been previously reported in this condition. A review of the behavioural problems in Lujan-Fryns syndrome and an approach to their management is discussed.

Female reproductive cycle and obsessive-compulsive disorder.
BACKGROUND: The aim of our study was to assess whether there is a relationship between reproductive cycle events and the initiation or changes in symptoms of obsessive-compulsive disorder (OCD). METHOD: Forty-six female outpatients meeting DSM-IV criteria for OCD completed a semistructured interview at our OCD unit to assess the relationship between reproductive cycle events and OCD. Dates of data collection were from January 2001 to December 2003. RESULTS: In our sample, OCD onset occurred in the same year as menarche in 22% (N = 10), at pregnancy in 2% (N = 1), at postpartum in 7% (N = 3), and at menopause in 2% (N = 1). Worsening of preexisting OCD was reported by 20% of patients (9/45) at premenstruum, 8% (1/12) at pregnancy, 50% (6/12) at postpartum, and 8% (1/12) at menopause. The number of premenstrual mood symptoms, which included anxiety, irritability, mood lability and depressed mood, was associated with both premenstrual worsening of OCD (OR = 5.1, p < .01) and onset or worsening of OCD at postpartum (OR = 2.7, p < .05). Patients with an onset or worsening of OCD at postpartum also more frequently reported pre-menstrual worsening of OCD and previous history of major depressive disorder, including postpartum depression (p < or =.05 for all). CONCLUSION: In a substantial number of patients, the onset or worsening of OCD was related to reproductive cycle events, especially at menarche and postpartum. Certain women with OCD seem to be vulnerable to worsening of OCD at different reproductive periods that imply hormonal fluctuations, and premenstruum and post-partum were the 2 reproductive events with a greater vulnerability. Those patients whose OCD symptoms appeared to be related to reproductive events also exhibited a greater history of mood symptoms (premenstrual depression and major depressive episodes).

High sensitivity to punishment and low impulsivity in obsessive-compulsive patients with hoarding symptoms.
Recent factor-analytic studies involving over 2000 patients have reduced the symptoms of obsessive-compulsive disorder (OCD) into a few dimensions or potentially overlapping syndromes. Hoarding consistently emerged as a separate factor in all these studies. This study investigated the relationship between OCD symptom dimensions and normal personality traits in a sample of 56 OCD patients. They were administered the Sensitivity to Punishment and Sensitivity to Reward Questionnaire and the Eysenck Personality Questionnaire, derived from Gray's and Eysenck's personality models, respectively. The personality scores were correlated with previously identified symptom dimensions from the Yale-Brown Obsessive-Compulsive Scale Symptom Checklist (Y-BOCS-SC), controlling for overall illness severity. High scores on the hoarding dimension of the Y-BOCS-SC were positively correlated with scores on the Sensitivity to Punishment scale and negatively with Eysenck's Psychoticism scale. While high sensitivity to punishment is a personality feature common to many OCD patients, it is more strongly pronounced in patients with hoarding symptoms. These patients also appear to be less impulsive or novelty seeking as reflected by low scores on Eysenck's Psychoticism scale. High sensitivity to punishment and low novelty seeking in OCD hoarders might explain their poor compliance and response to conventional treatments, but this question needs to be explored further in a prospective treatment study.

Perceived parental rearing style in obsessive-compulsive disorder: relation to symptom dimensions.
Obsessive-compulsive disorder (OCD) runs in families, but the specific contribution of genetic and environmental factors to its development is not well understood. The aim of this study was to assess whether there are differences in perceived parental child-rearing practices between OCD patients and healthy controls, and whether any relationship exists between parental characteristics, depressive symptoms and the expression of particular OCD symptom dimensions. A group of 40 OCD outpatients and 40 matched healthy controls received the EMBU (Own Memories of Parental Rearing Experiences in Childhood), a self-report measure of perceived parental child-rearing style. The Yale-Brown Obsessive-Compulsive Scale (Y-BOCS) and the Hamilton Depression Rating Scale (HDRS) were used to assess the severity of obsessive-compulsive and depressive symptoms. The Y-BOCS Symptom Checklist was used to assess the nature of obsessive-compulsive symptoms, considering the following five symptom dimensions: contamination/cleaning, aggressive/checking, symmetry/ordering, sexual/religious and hoarding. Logistic and multiple linear regression analyses were conducted to study the relationship between parental style of upbringing, depressive symptoms and OCD symptom dimensions. Severe OCD (Y-BOCS: 27.0+/-7.4) and mild to moderate depressive symptoms (HDRS: 14.0+/-5.4) were detected in our sample. Compared with healthy controls, OCD patients perceived higher levels of rejection from their fathers. No differences between the groups with respect to perceived levels of overprotection were detected. The seventy of depressive symptoms could not be predicted by scores on any perceived parental characteristics. Hoarding was the only OCD symptom dimension that could be partially predicted by parental traits, specifically low parental emotional warmth. Social/cultural variables such as parental child-rearing patterns, in interaction with biological and genetic factors, may contribute to the expression of the OCD phenotype.

Mapping structural brain alterations in obsessive-compulsive disorder.
BACKGROUND: Recent technical developments have made it feasible to comprehensively assess brain anatomy in psychiatric populations. OBJECTIVE: To describe the structural brain alterations detected in the magnetic resonance images of a large series of patients with obsessive-compulsive disorder (OCD) using imaging procedures that allow the evaluation of volume changes throughout the brain. DESIGN: Case-control study. SETTING: Referral OCD unit in a tertiary hospital. PARTICIPANTS: A consecutive sample of 72 outpatients with OCD and 72 age- and sex-matched control subjects. INTERVENTIONS: Three-dimensional sequences were obtained in all participants. A statistical parametric mapping approach was used to delineate possible anatomical alterations in the entire brain. To preserve volumetric information, voxel values were modulated by the Jacobian determinants (volume change measurement) derived from spatial normalization. MAIN OUTCOME MEASURES: Voxelwise brain volumes. RESULTS: The brains of patients with OCD showed reduced gray matter volume in the medial frontal gyrus, the medial orbitofrontal cortex, and the left insulo-opercular region. A relative increase in gray matter volume was observed bilaterally in the ventral part of the putamen and in the anterior cerebellum. All these brain alterations were abnormally correlated in patients with OCD, and age statistically significantly contributed to the relative enlargement observed in the striatal areas. Disease severity, the nature of symptoms, and comorbidities were not related to the changes described. Nevertheless, patients with prominent aggressive obsessions and checking compulsions showed reduced amygdala volume in the right hemisphere. CONCLUSIONS: The pattern of anatomical features depicted by this voxelwise approach is consistent with data from functional studies. The reported anatomical maps identified the specific parts of the frontostriatal system that were altered in patients with OCD and detected changes in anatomically connected distant regions. These data further define the structural brain alterations in OCD and may contribute to constraining the prevailing biological models of this psychiatric process.

Personality characteristics in obsessive-compulsive disorder and individuals with subclinical obsessive-compulsive problems.
OBJECTIVE: To assess the relationship between normal personality traits and obsessive-compulsive (OC) phenomena in individuals with subclinical OC problems and patients whose problems met diagnostic criteria for obsessive-compulsive disorder (OCD). METHOD: In Study 1, 25 healthy volunteers with high scores on the Padua Inventory (PI) and 28 controls with low scores on the PI were compared on the Sensitivity to Punishment and Sensitivity to Reward Questionnaire (SPSRQ), the Eysenck Personality Questionnaire (EPQ), and measures of depression and state anxiety. In Study 2, 56 treatment-seeking participants meeting DSM-IV criteria for OCD and 40 healthy volunteers of similar sociodemographic characteristics were compared on the same measures. RESULTS: Both individuals with subclinical OC problems and OCD patients scored significantly higher than their respective control groups on sensitivity to punishment, neuroticism and psychoticism. OCD patients, but not individuals with subclinical OC problems, scored lower in extraversion than their respective controls. Neuroticism was the strongest predictor of high scores on the PI in Study 1, while psychoticism was the strongest predictor of the presence of an OCD diagnosis in Study 2. CONCLUSION: Healthy participants with high scores on OC measures and OCD patients share various personality traits but can also be distinguished according to the level of extraversion, neuroticism and psychoticism.

Relation of neurological soft signs to nonverbal memory performance in obsessive-compulsive disorder.
Few studies have examined the relation between neurological soft signs (NSS) and neuropsychological performance in Obsessive-Compulsive Disorder (OCD). Thirty outpatients with primary OCD and 30 matched normal controls were administered the Cambridge Neurological Inventory and the Rey-Osterrieth Complex Figure Test (RCFT). A series of multiple regression models tested the relationship between NSS and performance on the RCFT. Patients presented significantly more neurological soft signs than controls on both sides of the body, and were impaired on the free recall and organization scores of the RCFT. Nonverbal memory deficits in OCD were predicted independently by organizational strategies during the copy condition of the RCFT, and neurological soft signs. There might be at least two variables independently mediating nonverbal memory deficits in OCD: (1) a cognitive organization and planning component, and (2) a complex motor regulatory component.

Neuropsychological performance in medicated vs. unmedicated patients with obsessive-compulsive disorder.
To date, there have been no formal investigations of neuropsychological performance in patients with obsessive-compulsive disorder (OCD) taking psychotropic medications. The purpose of this study was to determine whether medicated and unmedicated patients with OCD demonstrate differences in neuropsychological functioning. Fifty-two patients with a primary DSM-IV diagnosis of OCD participated in the study; 28 were taking serotonin reuptake inhibitors (SRIs), and 24 were treatment-naïve (n=8) or had finished a washout period prior to their inclusion in other studies (n=16). The groups were well matched with regard to demographic and clinical variables, including symptom severity. Each group was administered a comprehensive neuropsychological battery to assess general intelligence, attention, verbal and non-verbal working memory, declarative and procedural learning, visuo-constructive skills, and executive functions. SRI-medicated did not differ from SRI-free patients on any neuropsychological measure. Benzodiazepines seemed to improve the patients' functioning on a semantic verbal fluency test. In addition, there were significant interactions between SRIs and benzodiazepines on the perseverative errors of the Wisconsin Card Sorting Test and on reaction times. SRI-medicated patients with OCD are able to perform on cognitive functioning tests at a comparable level with that of SRI-free patients, and these results have positive implications for OCD patients who respond to SRIs. The interactions between SRIs and benzodiazepines and their effect on cognition in OCD are likely to be complex and deserve further study.

Convergent and discriminant validity of the Yale-Brown Obsessive-Compulsive Scale Symptom Checklist.
BACKGROUND: The factor structure of the Yale-Brown Obsessive-Compulsive Scale Symptom Checklist (Y-BOCS-SC) has been well established, but its convergent and divergent reliability have yet to be studied. METHODS: Fifty-six obsessive-compulsive disorder (OCD) patients were administered the clinician-administered Y-BOCS-SC and Hamilton Rating Scale for Depression (HRSD), together with the self-administered Maudsley Obsessive Compulsive Inventory (MOCI), Padua Inventory (PI), State-Trait Anxiety Inventory (STAI), and Beck Depression Inventory (BDI). RESULTS: Overall, the correspondence between the Y-BOCS-SC and self-administered measures of OCD symptoms was poor to moderate. Its convergent validity was adequate for its washing dimension but poor for its other dimensions. The discriminant validity of the Y-BOCS-SC was adequate, showing little overlap with overall illness severity (total Y-BOCS) and state measures (BDI, STAI, HRSD). In contrast, self-administered OCD measures were significantly correlated with overall illness severity and state measures. CONCLUSIONS: The convergent validity of the Y-BOCS-SC was generally poor and this could only be partially explained by the incomplete coverage of some OCD symptoms in the self-administered scales. Its discriminant validity was good. Both self- and clinician-administered measures should be used in OCD research, as they seem to measure relatively non-overlapping constructs. Further research on the psychometric properties of the Y-BOCS-SC is needed.
