Myelomeningocele: the management of the associated hydrocephalus
No full textThe pathogenesis of the hydrocephalus associated with myelomeningocele (MMC) has been the subject of an extensive number of studies. The contemporary reduction of the incidence of the Chiari II malformation and of the associated active hydrocephalus after closure of the spinal defect in utero is in line with previous studies suggesting a prominent role of the posterior cranial fossa abnormalities, where even the increased venous pressure might be at least mostly a consequence of the constriction of the posterior cranial fossa structures. Pure absorptive abnormalities however coexist, the main ones documented to be abnormal cisternal spaces and peculiar cerebrospinal fluid chemical features
Dietary approach to prevent obesity risk in Spina Bifida patients
No full textPURPOSE:
The aim of this prospective, analytic study is to evaluate if dietary approach can improve the body mass index (BMI) in a total of N = 152 patients with SB.
METHODS:
BMI levels were evaluated stratifying patients by gender and age classes. Patients with BMI ≥ 25 have been randomized (1:1) in two groups: the "diet" group that received a dietary program and the "no diet" group that did not receive any program. Patients have been observed at the beginning of the study (T0), and again at the end of the study, 1 year later (T1). The main objective of the study was to evaluate BMI score in SB patients and how it could be influenced by dietary changes.
RESULTS:
A total of 36.8% patients were classified as overweight or obese. Females present a mean BMI level higher than male, and patients older than 20 years old present the highest mean BMI. The "diet" group BMI decreased from 29.7 (± 3.8) to 27.7 (± 3.7) during the year of program. The mean BMI in the "no diet" group decreased from 30.3 (± 4.6) to 29.2 (± 4.7). There was a statistically significant difference in BMI level between groups (p < 0.0005). There was a statistically significant effect of time on BMI levels for the "diet program" group (p = 0.001), and there was NOT a statistically significant effect of time on BMI levels for the "no diet group" (p = 0.053).
CONCLUSIONS:
Spina Bifida population has high risk of obesity which is related to other comorbidities such as diabetes and hypertension for example. Specific dietary program, since pediatric age, correlates with an improvement of quality of life, a reduction of BMI and of risk of related diseases with obesity. This study confirms that the transition to adulthood marks the beginning of the overweight status for many SB patients, but it also demonstrates that, following a dietary program, even disabled patients with limited training capabilities can achieve a BMI reduction
New micro-hole zone catheter reduces residual urine and mucosal microtrauma in a lower urinary tract model
Full text linkUrinary tract infections (UTIs) are the main complication associated with clean intermittent catheterization (CIC) and are facilitated by post-void residual urine and trauma to the mucosa during voiding. The risk of UTI may be diminished by reducing the residual volumes and preventing microtrauma caused by mucosal suction through the eyelets of conventional eyelet catheters (CEC). A new micro-hole zone catheter (MHZC) was developed and tested in an ex vivo porcine lower urinary tract model and in vivo, in pigs, against a CEC. It was shown that, irrespective of the micro-hole diameter, the new catheter ensured increased flowrates and significantly lower residual volumes at the first flow-stop. Furthermore, with a micro-hole diameter of 0.4 mm, mucosal suction was virtually eliminated, regardless of the insertion depth or simulated intra-abdominal pressure mimicking sitting or standing humans. Pressure profile experiments and endoscopy studies indicated that the bladder gradually folds against the drainage tip of the new catheter, without blocking the flow, and, unlike with the CEC, sharp pressure variations and flow-stops did not occur during voiding. The MHZC outperformed the CEC in all tested scenarios and decreased residual volumes, thus potentially decreasing the risk of UTIs
No Correlation between X Chromosome Inactivation Pattern and Autistic Spectrum Disorders in an Italian Cohort of Patients
No full textAutistic spectrum disorders (ASD) occur more frequently in males, suggesting a major pathogenic role for genes located on the X-chromosome. The analysis of X chromosome inactivation (XCI) pattern may help to identify XCI skewing in those families in which such genes are involved, even without identifying the specific genetic mutation. In order to identify such families, we determined the XCI pattern in 40 females with ASD and 58 mothers of children with ASD, as well as in 80 matched control females. We could not detect any skewing in mothers of ASD children nor in ASD females. However, it cannot be ruled out that a different XCI pattern is present in the brain or that other, unexplored X-linked loci might undergo segmental or locus specific XCI skewing

Prevalence of latex allergy in spina bifida: genetic and environmental risk factors.
No full textAIM OF STUDY: To evaluate the prevalence of latex allergy in a population of children with spina bifida (SB) and to assess the role of early exposure to latex products and others risk factors.
INTRODUCTION: SB is related with an higher incidence of latex allergic reactions. These patients received repeated surgical procedures, implant of latex-containing materials and catheterization.
MATERIALS AND METHODS: Eighty consecutive subjects affected with SB besides answering a questionnaire, underwent a skin-prick test (SPT) to latex and the determination of the specific serum IgE (RAST CAP) to latex. 40% (32/80) of the patients showed a latex sensitization with specific IgE > 0.7 kU/I but only twelve of the 32 sensitized patients (40%) suffered from clinical reactions to latex (urticaria, conjunctivitis, angioedema, rhinitis, bronchial asthma). Number of surgical procedures, but particularly early exposure to latex and familiarity for allergy are correlated with latex allergy (p < 0.01).
CONCLUSION: Latex allergy in SB children is multifactorial situation related with a disease-associated propensity for latex sensitization, early exposure and number of surgical procedures. Prophylactic measures to avoid the exposure, not only in the sanitary environment, through the institution of latex-safe routes and every day, prevent potentially serious allergic reactions
GDNF PLASMA LEVELS IN SPINA BIFIDA: CORRELATION WITH SEVERITY OF SPINAL DAMAGE AND MOTOR FUNCTION
No full textGlial-derived neurotrophic factor (GDNF) is one of several powerful survival factors for spinal motoneurons that play a key role in sprouting, synaptic plasticity, and reorganization after spinal cord damage. The aim of this study was to investigate the expression of GDNF in plasma of children with spina bifida (SB) and to determine its correlation with both the severity of spinal cord damage and the motor function of these patients. To measure the GDNF expression, we collected plasma samples from 152 children with SB and in 149 matched controls. Endogenous GDNF levels were quantified using a two-site immuno-enzymatic assay. The statistical analysis was performed using the Mann-Whitney two-tailed two-sample test. In children with SB the mean levels of GDNF (131.2 +/- 69.6 pg/mL) were significantly higher (p < 0.001) with respect to the mean levels of the control group (102.7 +/- 6.8 pg/mL). Moreover, in open SB, the GDNF levels (139.2 +/- 81.1 pg/mL) were significantly higher (p < 0.05) with respect to closed SB (117.2 +/- 41.3 pg/mL). In terms of the motor function of patients, we found that in children with poorer motor function, the GDNF levels (134.5 +/- 67.4 pg/mL) were higher, but not statistically significant (p < 0.1), than in patients with better motor outcome (122.3 +/- 72.2 pg/mL). Our study demonstrates GDNF over-expression in children with SB. This upregulation is significantly associated with the severity of spinal cord damage in SB patients and appears to correlate with poor motor function of children, representing an important biochemical marker of the severity of spine injury
Longitudinal study of microvascular involvement by nailfold capillaroscopy in children with Henoch-Schönlein purpura
No full textThe aim of this study is to describe by video-nailfold capillaroscopy the microvascular involvement and capillary changes in children with Henoch-Schönlein purpura (HSp) and to establish a possible correlation with clinical outcome. Thirty-one patients underwent capillaroscopic evaluation through a videomicroscope during the acute phase and after 6 months. Twenty sex/age-matched controls were also examined. All capillaroscopic variables were statistically examined in combination with laboratoristic/clinical data. Architectural and morphological changes recorded during the acute phase were statistically significant in comparison to the controls (p < 0.01). At the follow-up, oedema was still observed in all patients, whereas, morphological changes only in two. There was a no significant correlation between capillaroscopy changes, laboratoristic/clinical data, and outcome. Video-nailfold capillaroscopy can be a simple tool to evaluate microvascular abnormalities in the acute phase of HSp, and the persistence of oedema could suggest an incomplete disease resolution at a microvascular level
