--- abstract: |- Summary: We tested the hypothesis that gestational injuries in some patients with schozophrenia would leave their mark as a subtle reduction in head circumference (subclinical microcrania). Conclusions: The head circumferences of all subjects were in the normal range. Decreased head circumference in affected MZ co-twins (relative to unaffected MZ co-twin) characteriazes discordant MZ pairs with larger finger-ridge-count differences (i.e., second-trimester fetal-size differences). This study using ideal genetic controls suggests that, while present only in some patients with schizophrenia, the decrease in head circumference is most likely a consequence of in-utero nonshared environmental deleterious events manifesting as groth retardation or as fetal edema and occurring around the fifth prenatal month. altloc: [] chapter: ~ commentary: ~ commref: ~ confdates: ~ conference: ~ confloc: ~ contact_email: ~ creators_id: [] creators_name: - family: Bracha given: HS honourific: '' lineage: '' - family: Gil given: P honourific: '' lineage: '' - family: Lange given: B honourific: '' lineage: '' - family: Gilder given: J honourific: '' lineage: '' - family: Torrey given: EF honourific: '' lineage: '' - family: Gottesman given: II honourific: '' lineage: '' - family: McCray given: DS honourific: '' lineage: '' date: 1995 date_type: published datestamp: 2006-12-22 department: ~ dir: disk0/00/00/53/00 edit_lock_since: ~ edit_lock_until: ~ edit_lock_user: ~ editors_id: [] editors_name: [] eprint_status: archive eprintid: 5300 fileinfo: /style/images/fileicons/application_pdf.png;/5300/1/Bracha_et_al.%2C_Subclinical_microcrania%2C_subclinical_macrocrarnia%2C_and_fifth%2Dmonth_fetal_markers_(of_growth_retardation_or_edema)_in_schizophrenia_a_co%2Dtwin_control_study_of_discordant_monozygotic_twins..PDF full_text_status: public importid: ~ institution: ~ isbn: ~ ispublished: pub issn: ~ item_issues_comment: [] item_issues_count: 0 item_issues_description: [] item_issues_id: [] item_issues_reported_by: [] item_issues_resolved_by: [] item_issues_status: [] item_issues_timestamp: [] item_issues_type: [] keywords: 'Schizophrenia, Etiology, Embryology, Neurodevelopment, Dysmorphology, Dermatoglyphics, Twins, Monozygotic, Nonshared environment' lastmod: 2011-03-11 08:56:44 latitude: ~ longitude: ~ metadata_visibility: show note: ~ number: 1 pagerange: 44-52 pubdom: FALSE publication: 'Neropsychiatry, Neuropsychology, and Behavioral Neurology' publisher: ~ refereed: FALSE referencetext: ~ relation_type: [] relation_uri: [] reportno: ~ rev_number: 10 series: ~ source: ~ status_changed: 2007-09-12 17:08:53 subjects: - neuro-psych - neuro-neu succeeds: ~ suggestions: ~ sword_depositor: ~ sword_slug: ~ thesistype: ~ title: 'Subclinical microcrania, subclinical macrocrarnia, and fifth-month fetal markers (of growth retardation or edema) in schizophrenia: a co-twin control study of discordant monozygotic twins.' type: journalp userid: 6567 volume: 8
