Schistosomal myeloradiculopathy due to Schistosoma mansoni: report on 23 cases

Schistosoma mansoni infection is likely to be responsible for a significant proportion of cases of myelopathy occurring in areas where schistosomiasis is endemic. The aim of this study is to describe the clinical, laboratory and therapeutic data of 23 patients with schistosomal myeloradiculopathy. The medical records of 23 patients with schistosomal myelopathy admitted to two general hospitals of Belo Horizonte (MG), in Brazil, from 1995 to 1999, were reviewed retrospectively. Seventeen patients were male (74%). The mean age for the whole group was 27 years. Lower limb weakness and associated lumbar and/or lower limb pain were reported by 20 patients (87%), and 16 (70%) were unable to walk. All individuals presented urinary retention and 19 (83%) complained of intestinal dysfunction. The treatment was based on the association of antischistosomal drugs and corticosteroids. Five patients (22%) presented a full response to treatment, 13 (57%) partial response without functional limitations and 4 (17%) partial improvement with limitations or no response. Three out of the 4 patients who stopped steroids before 45 days of treatment developed recurrence of the symptoms and signs of myelopathy. Our cases demonstrate the severe presentation of the disease and the data disclosed here suggest that treatment with steroids should be kept for months after clinical improvement.

Leucemias agudas secundarias a tratamiento con quimioterapia y/o radioterapia: estudio de 23 pacientes en un solo centro.

L’ús d’agents citotòxics ha incrementat la incidència de leucèmies agudes secundàries (LAS). De 23 LAS diagnosticades en 20 anys, s’analitzaren els agents citotòxics, caraterístiques clínico-biològiques, tractament i pronòstic. Els agents rebuts a la neoplàsia prèvia fóren: alquilants, inhibidors de la DNA topoisomerasa II, antitubulina i radioteràpia. El 95% de les LAS presentàven alteracions citogenètiques. Tretze pacients reberen quimioteràpia intensiva (amb un trasplantament de progenitors hematopoètics [TPH] en 3) i 10 només suport (supervivència mediana de 3 en front a 0,079 anys, p=0,004). El pronòstic i la resposta al tractament fóren dolents, però associaciar quimioteràpia i TPH podria perllongar la supervivència.

This Symposium, hosted by Dementia Services Information and Development Centre, opened up debate on formal and informal care for people with dementia living in the community and in residential care. ��It also discussed recent research findings on dementia care in Ireland and the United States.Click the link to view the following presentation slides:Professor Steve Zarit - Caregiving at a Cross-Roads; Bridging the Gap between Science and PracticeProfessor Eamon O'Shea - Costing Care for People with Dementia in IrelandDr Caroline O'Nolan - Longterm Residential Care for People with Dementia in Ireland: New Findings from a National SurveyDr Ana Diaz - "I Have a Good Life, I just want to Keep it"; Subjective Understandings and Objective Evaluations of Quality of Life after Diagnosis of DementiaProfessor Charles Normand - Burdens and Paradoxes in Caregiving

FGF receptors control vitamin D and phosphate homeostasis by mediating renal FGF-23 signaling and regulating FGF-23 expression in bone.

The functional interaction between fibroblast growth factor 23 (FGF-23) and Klotho in the control of vitamin D and phosphate homeostasis is manifested by the largely overlapping phenotypes of Fgf23- and Klotho-deficient mouse models. However, to date, targeted inactivation of FGF receptors (FGFRs) has not provided clear evidence for an analogous function of FGFRs in this process. Here, by means of pharmacologic inhibition of FGFRs, we demonstrate their involvement in renal FGF-23/Klotho signaling and elicit their role in the control of phosphate and vitamin D homeostasis. Specifically, FGFR loss of function counteracts renal FGF-23/Klotho signaling, leading to deregulation of Cyp27b1 and Cyp24a1 and the induction of hypervitaminosis D and hyperphosphatemia. In turn, this initiates a feedback response leading to high serum levels of FGF-23. Further, we show that FGFR inhibition blocks Fgf23 transcription in bone and that this is dominant over vitamin D-induced Fgf23 expression, ultimately impinging on systemic FGF-23 protein levels. Additionally, we identify Fgf23 as a specific target gene of FGF signaling in vitro. Thus, in line with Fgf23- and Klotho-deficient mouse models, our study illustrates the essential function of FGFRs in the regulation of vitamin D and phosphate levels. Further, we reveal FGFR signaling as a novel in vivo control mechanism for Fgf23 expression in bone, suggesting a dual function of FGFRs in the FGF-23/Klotho pathway leading to vitamin D and phosphate homeostasis.
