    Genetic Variation for Anther Callus Inducibility in Crosses of Highly Culturable Winter Wheats (1992)

    Notes: Heritability studies suggest that variation among genotypes for callus inducibility should respond to selection. The objective of this study was to determine if crosses among parents with high callus initiation frequencies would produce segregation from which genotypes with improved callus inducibility could be selected. The winter wheat (Triticum aestivum L.) cultivars‘Centurk 78’, ‘Norstar’ and ‘Norwin’ were chosen as parents, based on their high callus initiation frequencies and diverse parentage. F2 populations from crosses between each of these parents were evaluated for callus initiation frequencies and callus vigor as determined by growth rate and healthy appearance. Heterosis was detected for callus initiation in the‘Norwin’בNorstar’ cross and for callus vigor in all crosses. Broad sense heritability estimates of 0.25 and 0.37 for callus initiation in the ‘Centurk 78’בNorstar’ and ‘Norwin’בNorstar’ crosses, respectively, suggest this trait can be improved by selection. Heritability estimates for callus vigor were less promising, ranging from 0.11 to 0.24.

    Changes in echogenicity of spinal subarachnoid space associated with intracranial hemorrhage: new observations (2000)

    Notes: Abstract Purpose. The role of subarachnoid blood and secondary, sterile inflammation in the pathogenesis of posthemorrhagic hydrocephalus (PHH) is not well understood. The aims of this study were to study the frequency and rate of spread of blood into the spinal subarachnoid space (SSS) and to evaluate the relationship of this finding and PHH.¶Materials and methods. Nine premature babies with major intracerebral hemorrhage (ICH, grade 3 or higher), and ten premature infants with minor ICH (grade 1) or no evidence of ICH (control group) were identified and underwent serial cranial and spinal sonography at the time of initial diagnosis, 12–24 h after the ICH and weekly thereafter for at least 9 weeks. Sagittal and axial scans of the thoracolumbar spine were obtained and evaluated for the presence of echogenic debris in the dorsal SSS. Six additional patients who had cranial and spinal sonography died within the 1st week of life and underwent post-mortem examinations.¶Results. The SSS was echo-free (normal) in all cases at the time of initial sonographic diagnosis of ICH. Within 24 h, all babies with major ICH had developed increased echogenicity of the cervical and thoracic SSS. Echogenicity of the SSS decreased gradually over several weeks. Although transient ventricular dilatation was present in every patient, only one patient had rapidly progressive PHH requiring shunt placement. Transient cysts of the cervicothoracic subarachnoid space were identified in two patients 6–7 weeks after ICH. The subarachnoid space remained echo-free in all control infants At autopsy, all four infants with echogenic spinal debris had blood or blood products in the spinal subarachnoid space, whereas two infants with echo-free spinal images did not.¶Conclusions. Spread of blood from the ventricular system into the spinal subarachnoid space after ICH is common and can be seen within 24 h of initial ICH. Subarachnoid blood is associated with post-hemorrhagic ventricular dilatation and transient spinal subarachnoid cyst formation.

    Plain abdominal radiographs in children with inflammatory bowel disease (1986)

    Notes: Abstract The value of plain abdominal radiography in children with inflammatory bowel disease (IBD) has not been ascertained. We reviewed the scout radiographys prior to first barium examination in 100 children with IBD [53 Crohn, 47 ulcerative colitis (UC) and scout films prior to excretory urography in 50 patients who had no clinical evidence of intestinal disease (controls)]. The films were reviewed without clinical information, and the abnormalities on each film scored according to severity and location. Criteria included: mural thickening, dilatation and mucosal abnormalities of the small bowel and colon, as well as abnormal quantity and/or distribution of feces in the colon. Eighty percent (40/50) of the films in the control group were interpreted as normal. Abnormalities suggestive of IBD were present in 73% of the IBD group (76% Crohn and 72% UC). Thirty-one percent of the films in the IBD group had a moderately abnormal score (〉=3) or markedly abnormal score (〉=5) at presentation. The most reliable radiographic findings were: mucosal abnormality in the colon and small bowel and an abnormal stool pattern (feces completely absent or only present in one colonic segment). The clinical presentation of IBD in childhood is often vague and nonspecific. Abnormalities in plain films of the abdomen are common in these patients and may be helpful in suggesting the presence and, to a great degree, the severity of disease in these children.

    Radiologic-Pathologic Conference of Children's Hospital Boston: New pulmonary nodules in a child undergoing treatment for a solid malignancy (1996)

    Notes: Abstract The appearance of pulmonary nodules in a child with a solid malignancy undergoing chemotherapy is a clinically worrisome event. The diagnosis in such cases is not always metastatic disease, and the differential diagnosis should include granulomatous disease, atelectasis, pneumonia, inflammatory pseudotumor, hamartoma, radiation pneumonitis, and bronchiolitis obliterans with organizing pneumonia. There is no consistent radiologic feature to help distinguish benign from malignant causes of these new lesions. However, repeat chest CT 4–6 weeks after the lesions are first noted can be used to track lesion progression and may obviate the need for biopsy.

    MRI evaluation of superficial soft tissue lesions in children (1993)

    Notes: Abstract The role of MRI in the evaluation of superficial soft tissue lesions in children has not been well established. We present our experience with MRI in the evaluation of nineteen children with a variety of cutaneous and subcutaneous lesions. We find MRI to have a definite role in the evaluation of these lesions particularly when determining extent or depth of involvement would affect medical or surgical management. MRI has a less well defined role in tissue determination. Spin echo T1 and T2 weighted images were sufficient for evaluation in most cases. Fat suppression images added additional information in fatty tumors. The MRI appearance of juvenile hyaline fibromatosis and lipoblastomatosis has not been previously described and is included in this study.
