Prophylaxis Effect of Metronidazole Vaginal Gel in Decreasing the Risk of Surgical Site Infections after Elective Hysterectomy.

Objective: Infections are an important cause of morbidity and mortality after hysterectomy. Here, we aimed to investigate and evaluate the beneficial effects of metronidazole vaginal gel on the rate of surgical site infections in women undergoing elective abdominal hysterectomy.

Methods: This is a randomized prospective, double-blind controlled clinical trial performed in 2020 in Isfahan on 108 candidates for elective hysterectomy.

Molecular imaging in alcohol dependence.

The cellular mechanisms of alcohol's effects in the brain are complex, targeting multiple transmitter systems. Molecular imaging has been used to study the effects of alcohol and alcohol use disorders on these various systems. Studies of dopaminergic indices have provided robust evidence for deficits in D2-mediated transmission in the striatum of chronic recently detoxified alcoholics.

The relationship between restrictive and repetitive behaviors in individuals with autism and obsessive compulsive symptoms in parents.

This study investigated the relationship between repetitive behaviors in individuals with autism and obsessive-compulsive behaviors in parents. We hypothesized that repetitive behaviors in probands with autism would be associated with increased obsessive-compulsive behaviors in parents in sporadic families (1 known case of autism per family and no known history of autism). Parents with clinically significant Y-BOCS scores were more likely to have a family history of obsessive-compulsive disorder.

Accelerated head growth in early development of individuals with autism.

Macrocephaly is one of the most consistent physical findings reported in autistic individuals. Previous studies attempted to determine if macrocephaly is associated with risk for autism. This study hypothesizes that an abnormal acceleration in head growth during early development, rather than macrocephaly, is associated with autism risk.

Factor analysis of restricted and repetitive behaviors in autism using the Autism Diagnostic Interview-R.

The current study examined the factor structure of restricted and repetitive behaviors (RRB) in children with autism. Factor extraction procedures of 12 items from the Autism Diagnostic Interview-Revised (ADI-R) were applied in N = 207 individuals with autism. Two interpretable factors were identified: Factor 1--repetitive sensory motor actions and Factor 2--resistance to change.

Identification of MeCP2 mutations in a series of females with autistic disorder.

Rett disorder and autistic disorder are both pervasive developmental disorders. Recent studies indicate that at least 80% of Rett Disorder cases are caused by mutations in the methyl-CpG-binding protein 2 (MeCP2) gene. Since there is some phenotypic overlap between autistic disorder and Rett disorder, we analyzed 69 females clinically diagnosed with autistic disorder for the presence of mutations in the MeCP2 gene.

Behavioral comparisons in autistic individuals from multiplex and singleton families.

Autistic disorder (AD) is a complex neurodevelopmental disorder. The role of genetics in AD etiology is well established, and it is postulated that anywhere from 2 to 10 genes could be involved. As part of a larger study to identify these genetic effects we have ascertained a series of AD families: Sporadic (SP, 1 known AD case per family and no known history of AD) and multiplex (MP, > or = 2 cases per family).

Fine mapping of autistic disorder to chromosome 15q11-q13 by use of phenotypic subtypes.

Autistic disorder (AutD) is a complex genetic disease. Available evidence suggests that several genes contribute to the underlying genetic risk for the development of AutD. However, both etiologic heterogeneity and genetic heterogeneity confound the discovery of AutD-susceptibility genes.

Association analysis of chromosome 15 gabaa receptor subunit genes in autistic disorder.

Gamma-aminobutyric acid (GABA) is the major inhibitory neurotransmitter in the brain, acting via the GABAA receptors. The GABAA receptors are comprised of several different homologous subunits, forming a group of receptors that are both structurally and functionally diverse. Three of the GABAA receptor subunit genes (GABRB3, GABRA5 and GABRG3) form a cluster on chromosome 15q11-q13, in a region that has been genetically associated with autistic disorder (AutD).

Phenotypic homogeneity provides increased support for linkage on chromosome 2 in autistic disorder.

Autistic disorder (AutD) is a neurodevelopmental disorder characterized by significant disturbances in social, communicative, and behavioral functioning. A two-stage genomic screen analysis of 99 families with AutD revealed suggestive evidence for linkage to chromosome 2q (D2S116 nonparametric sib-pair LOD score [MLS] 1.12 at 198 cM).

No association between the WNT2 gene and autistic disorder.

Autistic disorder is a pervasive neurodevelopmental disorder characterized by deficits in language and social communication, as well as stereotyped patterns of behavior. Peak LOD scores from several genomic screening efforts indicate the presence of an autistic disorder susceptibility locus within the distal long arm of human chromosome 7 (7q31-q35). Wassink et al.

Genomic screen and follow-up analysis for autistic disorder.

Autistic disorder (AutD) is a neurodevelopmental disorder characterized by significant impairment in social, communicative, and behavioral functioning. A genetic basis for AutD is well established with as many as 10 genes postulated to contribute to its underlying etiology. We have completed a genomic screen and follow-up analysis to identify potential AutD susceptibility loci.

Genetic studies in autistic disorder and chromosome 15.

Autistic disorder (AD) is a developmental disorder affecting social interactions, communication, and behavior. AD is a disease of complex genetic architecture. It is postulated that several genes contribute to the underlying etiology of AD.

Three probands with autistic disorder and isodicentric chromosome 15.

We have identified three unrelated probands with autistic disorder (AD) and isodicentric chromosomes that encompass the proximal region of 15q11.2. All three probands met the Diagnostic and Statistical Manual of Mental Disorders, fourth edition [DSM-IV; American Psychiatric Association, 1994], and International Classification of Diseases ( ICD-10) diagnostic criteria for AD, confirmed with the Autism Diagnostic Interview -Revised (ADI-R).

Analysis of linkage disequilibrium in gamma-aminobutyric acid receptor subunit genes in autistic disorder.

Autistic disorder (AD) is a neurodevelopmental disorder characterized by abnormalities in behavior, communication, and social interactions and functioning. Recently, Cook et al. reported significant linkage disequilibrium with an AD susceptibility locus and a marker, GABRB3 155CA-2, in the gamma-aminobutyric acid(A) (GABA(A)) receptor beta3-subunit gene on chromosome 15q11-q13.

Genetic studies of autistic disorder and chromosome 7.

Genome-wide scans have suggested that a locus on 7q is involved in the etiology of autistic disorder (AD). We have identified an AD family in which three sibs inherited from their mother a paracentric inversion in the chromosome 7 candidate region (inv(7)(q22-q31.2)).
