Strumpell's Disease in a Family with Hereditary Focal Segmental Glomerulosclerosis

Strumpell's familial spastic paraplegia is a rare hereditary disease, clinically characterized by progressive disturbance of gait. Focal Segmental Glomerulosclerosis (FSGS) is a frequent glomerulopathy, with an extremely rare familial subtype. The cases of two brothers with Strumpell's disease are reported, who also developed glomerular renal disease, most probably familial FSGS. The genetics of the two disorders, Strumpell's paraplegia and familial FSGS, are discussed, together with the possibility of a parallel transmission.     

Rare manifestations of sirenomelia syndrome: a report of five cases

Five cases of sirenomelia presented with rare manifestations are discussed. Three neonates were born alive and died within 2 to 12 hours after birth. One case was the offspring of a triple in vitro fertilization pregnancy with history of early intrauterine death of one of the triplets. The main features included fusion of lower extremities (five of five), renal agenesis (three of five), polycystic renal dysplasia (two of five), anal atresia with large bowel hypoplasia (three of five), pulmonary hypoplasia (four of five), and single umbilical artery (five of five). Other features that have only rarely been associated with sirenomelia included concurrence of congenital heart disease and neuroblastoma, gallbladder agenesis, and upper extremity defects.     

A rare case of solitary fibrous tumor of the nasal cavity

Solitary fibrous tumor (SFT) arises in the pleura and less commonly in extrapleural sites. SFT can be found in various head and neck sites. SFTs of the nasal cavity and paranasal sinuses are extremely rare with only ten previously reported cases in the world literature. This case report presents an additional case of SFT of the nasal cavity underlining the benign pattern and the bleeding tendency of nasal SFT, that surgeons managing these tumors should be aware of. Diagnostic procedure, clinical and histopathological findings as well as immunoreactivity of this tumor are discussed, with a review of the current literature.     

Body dysmorphic disorder due to hirsutism in a patient treated with cyclosporin

Sir, Currently administered immunosuppression schemes usually includecyclosporin. Cyclosporin has brought about a revolution in patientprognosis and in renal graft survival, but, unfortunately, ithas many side effects [1,2]. While physicians are attentiveto the more serious and life threatening of these side effects,     

Pamidronate is an effective treatment for osteoporosis in patients with beta-thalassaemia

Osteoporosis in beta-thalassaemia is multifactorial; increased osteoclast function seems to play an important role in its pathogenesis. The aim of this study was to evaluate the effect of pamidronate on the osteoporosis of thalassaemia. To this effect we studied 26 patients who received this drug in doses of 30 or 60 mg i.v. once a month over 12 months. The effects were monitored by measuring bone mineral density (BMD) in association with markers of osteoclast function [soluble receptor activator of nuclear factor-kappa B ligand (sRANKL), osteoprotegerin (OPG)] and of bone remodelling [N-telopeptide of collagen type-I (NTX), tartrate-resistant acid phosphatase isoform-5b (TRACP-5b), bone-alkaline phosphatase (bALP), and osteocalcin (OC)]. Thirty healthy individuals were also studied, as controls. NTX, TRACP-5b, bALP and OC levels were significantly higher in thalassaemic patients compared with controls; in contrast, OPG levels were significantly lower, while the levels of sRANKL varied within normal limits. Administration of pamidronate was followed by a clear decrease of NTX, TRACP-5b, OPG, and OC, and by a significant increase in the BMD of the lumbar spine, which was similar in patients of both treatment groups. These data suggest that pamidronate, at a monthly dose of 30 mg, is an effective treatment for thalassaemic osteoporosis.     

Magnetic resonance imaging in the evaluation of iron overload in patients with beta thalassaemia and sickle cell disease

Magnetic resonance imaging (MRI) appears to be useful for monitoring iron overload in thalassaemia. We studied 106 patients with beta-thalassaemia: 80 with thalassaemia major (TM) and 26 with thalassaemia intermedia (TI). Thirty-five patients with sickle cell disease (SCD) were also evaluated. Serum ferritin, liver and myocardial T2-relaxation time and liver iron concentration (LIC) were measured. LIC values, based on biopsies from 29 patients, showed a close inverse correlation with the respective liver T2-values, along with a strong positive correlation with ferritin levels in all patients. Heart T2-values correlated with left ventricular ejection fraction in TM and SCD, but not in TI patients. Both liver and heart T2-values were significantly lower in TM patients than those of TI, and SCD patients. Ferritin levels showed a strong correlation with liver T2-values in all three groups of patients. Similarly, a negative correlation was found between serum ferritin levels and heart T2-values in TM, but not in TI and SCD patients. Heart and liver T2-values showed a significant correlation only in TM patients. These results suggest that the MRI technique (T2 relaxation time) used in our study, is a reliable, safe and non-invasive method for the assessment of the deposition of iron in the liver; results for the heart become reliable only when there is heavy iron deposition.

Factors influencing the course and the response to treatment in primary focal segmental glomerulosclerosis.

BACKGROUND: The clinical course of primary focal segmental glomerulosclerosis (FSGS) varies and there is considerable controversy as to which factors are of importance in determining prognosis or response to therapy. The aim of this study was to identify clinical, pathological or immunohistochemical features at biopsy that could identify patients with progressive disease who might benefit from treatment, and predict long-term outcome. METHODS: The clinical and pathological findings of 33 adult patients with primary FSGS were retrospectively analysed in order to identify features at biopsy that could be predictive of outcome or response to treatment. For this purpose an immunohistochemical study was also performed, using monoclonal antibodies against intracellular adhesion molecules-1, C5b-9, alpha 3 beta 1 integrin, alpha-smooth-muscle actin (SMA), and TGF-beta1. RESULTS: At biopsy 17 patients (51%) were nephrotic and 16 (49%) non-nephrotic. Of the nephrotic patients, 11 were treated and six received only symptomatic therapy. Initial treatment with prednisolone (Pred) for 6-12 months (average 9 months) resulted in remission in 64% of nephrotic patients. To those with partial or no response, cyclosporin (CsA) or cyclophosphamide was given. At the end of follow-up (mean 57 months) three nephrotic patients (28%) were in complete remission, six (54%) in partial remission, and two (18%) did not respond to the treatment. In the seven treated non-nephrotic patients, Pred induced a complete remission in two (28%), a partial remission in three (44%), while two patients (28%) did not respond. Plasma creatinine remained stable in nephrotic patients who responded and it almost doubled in non-responders. Plasma creatinine also remained unchanged in treated non-nephrotic patients who responded to Pred, while two non-responders reached end-stage renal disease (ESRD). In contrast, 50% of untreated nephrotic patients and 67% of untreated non-nephrotic patients progressed to ESRD. Multivariate analysis showed only age and plasma creatinine at biopsy to have an independent predictive value for renal survival in nephrotic patients. This analysis also demonstrated that only the severity of interstitial fibrosis predicted the response to the treatment. In addition, the tubulointerstitial but not the glomerular expression of C5b-9, alpha 3 beta 1 integrin, alpha-SMA, and TGF-beta1 was significantly more extensive in non-responders and correlated with renal function at biopsy. However, only tubulointerstitial expression of TGF-beta1 independently correlated with the degree of renal function impairment at biopsy, but none of the above markers independently predicted renal survival or response to therapy. CONCLUSIONS: Nephrotic patients with FSGS may benefit from a more prolonged course of Pred. Nephrotic patients responding to treatment have a significantly better renal survival than non-responders. Age and plasma creatinine at biopsy are independent risk factors leading to ESRD. The severity of tubulointerstitial fibrosis is predictive of response to therapy.     

Examining the attitudes and physiological responses preservice learners have towards children with autism spectrum disorders

This study investigated attitudes and physiological responses demonstrated by preservice learners towards young children with autism spectrum disorders (ASD). The Self-Assessment Manikin (SAM) and two physiological measures (skin conductance and heart rate responses) were obtained. Four behaviors (two control and two problematic) depicting preschool-age males with ASD were viewed by preservice learners who either had limited (n = 15) or substantial experience (n = 15) in working with this population. Results revealed significant differences between behaviors (control versus problematic) on two out of three SAM ratings and on both physiological measures. Specifically, the results documented that regardless of level of experience, preservice learners exhibited increased arousal when watching problematic behaviors.
