RESUMEN
The patient was a 6-year-old girl with clinically isolated syndrome-like anti-myelin oligodendrocyte glycoprotein-associated disease (MOG-AD). Methylprednisolone pulse therapy resolved her cerebral lesion, and her visual acuity and field fully recovered after plasma exchange. This is the first case report presenting the therapeutic course in a child with clinically isolated syndrome-like MOG-AD. [J Pediatr Ophthalmol Strabismus. 2023;60(2):e11-e15.].

BACKGROUND: Wilms' tumor, aniridia, genitourinary anomalies, and mental retardation (WAGR) syndrome is a contiguous gene deletion syndrome caused by a de novo deletion including the 11p13 region. Although autism spectrum disorder (ASD) is frequently observed in patients with WAGR syndrome, few reports have comprehensively described its characteristics. We herein present the detailed neuropsychological and neurophysiological findings of a patient with WAGR syndrome complicated with severe psychomotor developmental delay and ASD. CASE PRESENTATION: The patient is presently a 6-year-old boy. Microarray analysis revealed a 7.1 Mb loss at 11p14.3-p13 and a 9.3 Mb loss at 11p13-p12, which encompassed the PAX6, WT1, and PRRG4 genes. His behavioral features were characteristic even among the ASD population: severe hypoesthesia to touch, pain, and temperature in addition to remarkable sensory seeking posing a high risk of serious accident. Sensory Profile analysis objectively identified a strong preference for sensory stimulation. Furthermore, his somatosensory evoked potential (SSEP) showed a mild delay in central conduction time, suggesting partial brain stem dysfunction-induced hypoalgesia. DISCUSSION: This first attempt to characterize sensory dysfunction using Sensory Profile and SSEP in WAGR syndrome may contribute to understanding its neuropsychological features and improve the quality of rehabilitation and socioeducational support in affected children.

Rubinstein-Taybi syndrome (RSTS) is a multisystem developmental disorder characterized by facial dysmorphisms, broad thumbs and halluces, growth retardation, and intellectual disability. In about 8% of RSTS cases, mutations are found in EP300. Previously, the EP300 mutation has been shown to cause the highly variable RSTS phenotype. Using exome sequencing, we identified a de novo EP300 frameshift mutation in a proband with coloboma, facial asymmetry and imperforate anus with minimal RSTS features. Previous molecular studies have demonstrated the importance of EP300 in oculogenesis, supporting the possibility that EP300 mutation may cause ocular coloboma. Since a wide phenotypic spectrum is well known in EP300-associated RSTS cases, the atypical phenotype identified in our proband may be an example of rare manifestations of RSTS.
RESUMEN
PURPOSE: To report the characteristics of Japanese shaken baby syndrome (SBS) in a regional Japanese children's hospital and verify previously reported idiosyncratic features that differ from those of SBS in Western countries: (1) a considerably higher frequency of mothers as perpetrators, (2) older ages of abusive parents, and (3) a higher rate of premature infant birth. METHODS: We reviewed medical charts obtained between 2002 and 2012 at Nagano Children's Hospital, Japan. RESULTS: Thirty-seven SBS cases with abusive head trauma were found, among which 11 (30 %) of the perpetrators were mothers, 9 (24 %) fathers, 3 (8 %) brothers, and 14 (37 %) involved both parents. A history of premature birth was present in 2 (5 %) of the cases. The mean age of the mother was 32.4 years and that of the father was 31.3 years. CONCLUSION: The clinical characteristics of Japanese SBS in this study are largely comparable to those seen in Western countries. Compared with the previously reported idiosyncratic features, there was a decreased predominance of mothers as perpetrators of SBS, suggestive of an increasing culpability of fathers. We also noticed that the ratio of premature births was more similar to those seen in Western surveys, while the mean ages of abusive Japanese parents remained older. Such varying results warrant a further nationwide survey.

New types of selective estrogen receptor modulators (SERMs) were synthesized and evaluated for their binding affinity and biological effect on reproductive cells. A proposed lead structure (B) was derivatized to provide compounds 30 and 44, which showed good estrogen-receptor binding affinity (K(i) values: 6.3 and 10 nM, respectively), as well as minimal impact on mammary and uterine carcinoma cells. Introduction of an alkyl group in the core structure considerably enhanced receptor-binding affinity of the compounds tested. Synthesis and structure-activity relationships of these compounds are described.
