Retroperitoneal approach for repair of inflammatory aortic aneurysms

Inflammatory aortic aneurysms (IAAs) are characterized by a markedly thickened aortic wall and dense perianeurysmal fibrosis. The presence of such inflammation and subsequent organ adherence makes surgical repair of IAAs more challenging than repair of simple atherosclerotic aneurysms. From March 1987 to June 1994, twelve patients underwent surgical repair of an IAA by a single surgeon. Ten patients were men (83%) and the mean age was 68.3 years (range 58 to 93 years). All patients except one were symptomatic with back or abdominal pain, yet none had evidence of aneurysm rupture at operation. Preoperatively 90% (9/10) of the patients had an elevated erythrocyte sedimentation rate (ESR), 100% (12/12) had a predictive CT scan, and all patients with aortic wall pathology specimens had their diagnosis confirmed. Six patients had a left flank retroperitoneal surgical approach, five had a transabdominal approach, and one had ligation and extra-anatomic reconstruction. The choice of repair technique was based on the degree and anatomic distribution of perianeurysmal fibrosis. The 30-day operative mortality rate was 0%. Mean follow-up was 56.3 months. Aortoduodenal fistula occurred in one patient 5 months after transperitoneal repair. Technical difficulties encountered during subsequent transperitoneal repairs led to the evolution of a policy in which the retroperitoneal approach was preferred in all patients with CT evidence of IAA. It is concluded that IAA represents a spectrum of retroperitoneal fibrosis and inflammation that is best treated surgically via a retroperitoneal approach.     

Metastatic cerebral choriocarcinoma coexistent with a viable pregnancy

Gestational choriocarcinoma associated with a viable pregnancy is extremely rare, and such choriocarcinoma with metastases presenting during the pregnancy is even more exceptional. Metastases from this tumor may present in a variety of ways depending on the site of the metastatic lesion, and can be fatal before choriocarcinoma is even suspected. We describe a 32-year-old primigravida presenting at 31 weeks gestation with a grand mal seizure due to cerebral metastases secondary to gestational choriocarcinoma who was subsequently successfully treated with chemotherapy. To our knowledge this is the first reported case of choriocarcinoma presenting with signs due to cerebral metastases during pregnancy where both the mother and child survived. This paper emphasizes the need to consider metastatic choriocarcinoma in any gravid female who presents with unusual neurological signs because of the life-threatening nature of this potentially curable disease.     

Child development and emergent literacy

Emergent literacy consists of the skills, knowledge, and attitudes that are developmental precursors to reading and writing. This article offers a preliminary typology of children's emergent literacy skills, a review of the evidence that relates emergent literacy to reading, and a review of the evidence for linkage between children's emergent literacy environments and the development of emergent literacy skills. We propose that emergent literacy consists of at least two distinct domains: inside-out skills (e.g., phonological awareness, letter knowledge) and outside-in skills (e.g., language, conceptual knowledge). These different domains are not the product of the same experiences and appear to be influential at different points in time during reading acquisition. Whereas outside-in skills are associated with those aspects of children's literacy environments typically measured, little is known about the origins of inside-out skills. Evidence from interventions to enhance emergent literacy suggests that relatively intensive and multifaceted interventions are needed to improve reading achievement maximally. A number of successful preschool interventions for outside-in skills exist, and computer-based tasks designed to teach children inside-out skills seem promising. Future research directions include more sophisticated multidimensional examination of emergent literacy skills and environments, better integration with reading research, and longer-term evaluation of preschool interventions. Policy implications for emergent literacy intervention and reading education are discussed.     

Oesophageal function in patiensts with angina (author's transl)

Oesophageal functions were measured in 18 patients with angina, 13 healthy volunteers and 29 age-matched patients with reflux disease. Acid clearance was as abnormal in angina patients (88 +/- 46 swallows) as in those with reflux disease (97 +/- 45). The pressure in the lower oesophageal sphincter was low in patients with angina (13 +/- 8 mm Hg). The incidence of hiatal hernia, subjective symptoms during acidification of the oesophagus and results of the reflux provocation test were similar in patients with angina pectoris and healthy controls.
