Obstetrical outcome of young women with a past history of cerebral venous thrombosis.

BACKGROUND: This study was designed to review the obstetrical outcome of a consecutive series of cerebral venous thrombosis (CVT) affecting fertile women over a long period of time. METHODS: From a computerized database of four hospitals of a French region (Poitou-Charentes), we selected patients admitted to hospital for CVT between January 1995 and February 2012. All the case notes were re-examined by two neurologists to confirm the initial diagnosis of CVT. The criterion of inclusion in our study was the occurrence of CVT in a woman ≤ 40 years of age. All the patients were recontacted by telephone in September 2012 and could be seen in an outpatient clinic. The data of interest were: occurrence of subsequent pregnancies, outcome of these pregnancies, their possible complications, their management with respect to preventive medication, details on the birth and the neonate. RESULTS: Out of 190 consecutive patients hospitalized for CVT, 62 women aged ≤ 40 years were included (mean age 27.2 ± 6.7 years at the time of their cerebrovascular event). The mean duration of follow-up was 89.5 ± 60.6 months (median: 76 months). There were 45 pregnancies in 24 of the women. Among these 45 pregnancies, 1 was in progress, 24 were completed resulting in normal children, whereas 20 were terminated (5 voluntary abortions, 14 miscarriages and 1 medical abortion). During the pregnancies recorded, there was one recurrence of CVT and no extra-CVT. Various management strategies were adopted, depending on the identified cause(s) for CVT and the medical history of the patient. CONCLUSIONS: Our study confirms that the occurrence of a CVT in young women is not a contraindication for subsequent pregnancy. However, it points to a high incidence of miscarriage. Apart from this fact, there is no increase in materno-fetal complications during pregnancy and childbirth, and the neonates are healthy. The risk of recurrence of a CVT or extra-CVT during subsequent pregnancy is low but most of patients were on preventive antithrombotic medication.

Neurological soft signs in OCD patients with early age at onset, versus patients with schizophrenia and healthy subjects.

Compelling evidence suggests that both schizophrenia and obsessive compulsive disorder (OCD) are related to deviant neurodevelopment. Neurological soft signs (NSS) have been proposed to be a marker of abnormal brain development in schizophrenia. The purpose of this study is to examine whether NSS are also a marker in patients with OCD, in particular, in early-onset OCD. The authors included 162 subjects and compared patients with OCD, patients with schizophrenia (SCZ), and healthy control subjects. They were all examined for NSS (Krebs' Scale), extrapyramidal symptoms (Simpson-Angus Scale), and were rated on the Abnormal Involuntary Movements Scale (AIMS). The authors found no differences between NSS total scores and subscores in OCD versus controls, whereas total NSS, motor coordination, and motor integration were significantly lower in OCD than in SCZ. OCD patients with early-onset (before age 13) did not differ from those with later-onset OCD. These results support the idea that NSS, as determined by current scales, is relatively specific to schizophrenia, although they do not preclude the existence of a neurological dysfunction in OCD. Further studies are required to determine the type of neurological signs that could be useful trait-markers in the phenotypic characterization of subtype OCD.
