Neuropsychological profiles in children and young adults with spina bifida.

PURPOSE: A total of 43 Italian children, aged between 6 and 16 years, diagnosed with spina bifida, myelomeningocele, and shunted hydrocephalus have been described clinically and completed a neuropsychological battery in order to evaluate their cognitive, personality, and behavior profile. METHODS: Enrolled children underwent cognitive assessment by means of the Weschler WISC-IV cognitive test and assessment of the attention sustained through the LEITER test. In addition, parents were asked, in order to obtain a personality and behavior profile of the children, to fill in a "CBCL 6-18 years" questionnaire and to fill in a Barthel Index questionnaire. RESULTS: Processing Speed Index of the WISC-IV QI scale was statistically significant (p = 0.027), with the highest value presented by autonomous patients (95.8 ± 12.8) and the lowest by patients using a wheelchair (75.5 ± 19). WISC-IV QI mean value is 98 (±15.7) for lipoma patients and 78.7 (±17.6) for LMMC and MMC patients (p = 0.001). In more detail, Perceptual Reasoning (p < 0.0005), Working Memory (p = 0.01), and Processing Speed Index (p = 0.001) highlighted a significant difference between the groups. The attention sustained subscale of the LEITER presented a mean of 6.9 (±3.1) for lipoma patients and a men value of 4.6 (±3.1) for LMMC and MMC patients (p = 0.024). Patients with hydrocephalus had statistically significant worse cognition and autonomy (Barthel Index) score (p < 0.001) compared with those without hydrocephalus, and normal scores regarding attention and depression scales. CONCLUSION: These results can be useful in planning dedicated therapeutic protocols such as suitable rehabilitation treatments, speech therapy, psychomotor skills, and cognitive enhancement and to develop prevention protocols particularly tailored for children with hydrocephalus who appear to have the more deficient skills.

Dietary approach to prevent obesity risk in Spina Bifida patients.

PURPOSE: 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.

Prenatal diagnosis, natural history, postnatal treatment and outcome of 222 cases of spina bifida: experience of a tertiary center.

OBJECTIVES: To report on the prenatal ultrasonographic diagnosis of spina bifida (SB) and its natural history, treatment and long-term outcome in a large tertiary referral center. METHODS: All cases of SB diagnosed between February 1980 and December 2015 in the Obstetric Prenatal Diagnosis Day Unit of the Obstetrics and Gynecology Department at the Catholic University of the Sacred Heart, Rome, were reviewed. All infants with an open defect were delivered by elective Cesarean section and underwent early repair of the spinal defect. A ventriculoperitoneal (VP) shunt and/or third ventriculostomy was performed when needed. Complete postnatal follow-up was carried out by our multidisciplinary team in the majority of cases. The cohort was analyzed in two groups: Group 1 included patients referred between February 1980 and December 1999; Group 2 included patients referred between January 2000 and December 2015. RESULTS: There was a total of 222 cases of SB with a prenatal diagnosis rate of 94.6% (n = 210), with the majority of defects being meningomyeloceles (n = 142 (64.0%)), affecting the lumbosacral level (n = 110 (49.5%)) and being ≥ 2 cm in size (n = 163/195 (83.6%)). There were 174 (78.4%) live births, with more terminations in Group 2 (26.1%) than in Group 1 (10.8%; P = 0.003). Postnatal surgical repair was conducted in 157 cases (99.4% of eligible cases), with death of an infant who was operated on occurring more often in Group 1 (14.1%) than in Group 2 (4.2%; P = 0.03). VP shunt placement was required in 60.3% of infants operated on after January 2000. Long-term follow-up was available for 136 children (111 with open defects and 25 with closed defects). Infants born since 2000 with an open defect had normal ambulation or a mild defect in 50% of cases and normal or mild deficit of sphincter function in 37.8% of cases. An intelligence quotient of ≥ 70 was observed in the majority of children (81.4%; 35/43 cases). Worse motor function was associated with progressive prenatal ventriculomegaly, level of lesion and VP shunt placement. CONCLUSIONS: We describe the prenatal diagnosis, natural history and long-term outcome of a large contemporary cohort of SB fetuses and infants. In an era of pioneering fetal surgical techniques for in-utero SB repair, it is important to acknowledge that advances in conventional neonatology and pediatric neurosurgery have allowed increased life expectancy and improved quality of life in patients with SB.

Occult spinal dysraphisms in newborns with skin markers: role of ultrasonography and magnetic resonance imaging.

PURPOSE: The purpose of this paper is to investigate occult spinal dysraphisms (OSD) using lumbar ultrasonography (LUS) in newborns presenting with specific skin markers or sacrococcygeal dimple. METHOD: From 2012 to 2015, we performed LUS in newborns with cutaneous stigmata and/or sacroccygeal dimple. Magnetic resonance imaging (MRI) was performed in all patients with abnormal ultrasound or features of neurological involvement in order to detect spinal lesions. RESULTS: We prospectively evaluated 475 newborns who presented cutaneous stigmata performing LUS during their 4 weeks of life though 439 completed the study. All patients had a follow-up of almost 12 months. Of these, 39 presented abnormal ultrasonography and underwent MRI. In this group, spinal dysraphism was confirmed in 12 patients. When considering skin markers, dermal sinus correlated with higher risk of spinal cord lesions, on the other hand the presence of simple sacral dimple alone denoted a very low risk of occult spinal dysraphism. The simultaneous presence of more skin markers and/or the presence of lumbar ultrasonography abnormality regarding the level of the conus, pulsatility, and the position of the cord, thickness of the filum terminale, or the presence of an intratecal mass, lipoma, or dermal sinus tract indicated the necessity to perform MRI in order to detect spinal cord abnormalities because of higher risk of spinal lesions. CONCLUSION: LUS in newborns with specific skin markers is a valid method to select patients in which MRI can be performed to detect OSD. The presence of a simple sacral dimple alone is a negligible marker for occult neural pathology while the presence of isolated dermal sinus or more than one cutaneous marker could be considered indicative of higher risk of spinal dysraphism.

Peristeen(®) transanal irrigation in paediatric patients with anorectal malformations and spinal cord lesions: a multicentre Italian study.

AIM: In paediatric and adult patients with neurogenic bowel, transanal irrigation (TAI) of the colon has gained popularity due to the introduction of a specifically designed device. The aim of this pilot study was to present the results of TAI using the Peristeen(®) TAI system in a group of paediatric patients with anorectal malformation (ARM) and congenital or acquired spinal cord lesions (SCLs). METHOD: Eight Italian paediatric surgery and spina bifida centres participated in the study. The inclusion criteria were age between 6 and 17 years, weight above 20 kg and unsatisfactory bowel management. Patients with chronic inflammatory bowel disease, mental disability and surgery within the previous 3 months were excluded. At the beginning of treatment (T0) and after 3 months (T1) the Bristol scale, a questionnaire assessing bowel function, and two questionnaires on quality of life (QoL) for patients aged 6-11 years (CHQ-pf50) and 12-17 years (SF36) were administered. RESULTS: Eighty-three patients were enrolled, and seventy-eight completed the study (41 ARMs, 37 SCLs). At T1, constipation was reduced in ARMs from 69% to 25.6% and in SCLs from 92.7% to 41.5%, faecal incontinence in ARMs from 50% to 18.6% and in SCLs from 39% to 9.8% and flatus incontinence in ARMs from 20.9% to 9.8% and in SCLs from 31.7% to 10%. At T0, the Bristol Stool Scale types were 1-2 in 45% of ARMs and 77.5% of SCL patients, whereas at T1 types 1-2 were recorded in only 2.5% of SCL patients. QoL improved in both groups. In the younger group, a significant improvement in QoL was recorded in ARM patients for eight of nine variables and in SCL patients for seven of nine variables. CONCLUSION: This study showed that Peristeen TAI resulted in a significant time reduction in colonic cleansing, increased independence from the carer and improved QoL in paediatric patients with ARMs and SCLs.

Audiological evaluation in children affected by myelomeningocele.

PURPOSE: The aim of the present study is to evaluate the auditory system in children affected by myelomeningocele and comparing the results with clinical neurological conditions. MATERIALS AND METHODS: Forty-three children, aged between 7 and 26 years, affected by myelomeningocele were investigated by means of subjective tonal audiometry and objective impedance audiometry (tympanometry and acoustic stapedial reflex). RESULTS: Audiological evaluation showed an alteration in 32 patients (74%%). Nine patients presented a mild hearing loss: bilateral in six cases (three sensorineural, one mixed, and two conductive) and unilateral in three cases (two mixed and one conductive). One patient had moderate unilateral conductive deafness and, finally another one severe unilateral sensorineural. Almost all patients with deafness were affected by myelomeningocele and Chiari II. Stapedial-cochlear reflex investigation showed an alteration in 30 patients (70%): 9 of these also showed deafness while the remaining 21 was normal hearing. In these 30 patients, we demonstrated the presence of myelomeningocele, hydrocephalus, and Chiari II malformation in 21 subjects (70%). CONCLUSION: Otoneurological evaluation is important in myelomeningocele not only at the birth but also in the follow-up. It could have an important prognostic role for neurological impairment.

Risk of fracture prevention in spina bifida patients: correlation between bone mineral density, vitamin D, and electrolyte values.

PURPOSE: The aim of our study was to investigate the relationship between bone mineral density (BMD), vitamin D, and electrolyte blood values in patients with spina bifida, to find a possible therapeutic regimen and an intervention to reduce the risk of fractures in this population. METHODS: BMD values were measured in 49 patients (32 females, 17 males; aged 14.1 ± 3.86 years; range 5-20 years) using dual-energy X-ray absorptiometry (DEXA) and were analyzed based on sex, the level of spinal involvement, vitamin D, and electrolyte values, physical activity, body mass index (BMI), and ambulatory status [patients were divided into three subgroups: full-time wheelchair (FTWC), limited ambulator (LA), and full-time ambulator (FTA)]. These data were analyzed considering sex-, age-, and BMD-matched values and compared with those of normal population. RESULTS: BMD was significantly lower in these patients compared with that in the general healthy population (Z-score: -1.2 ± 1.8); in particular, females had Z-score values significantly lower that of the males (Z-score: -2.43 ± 2.02; P < 0.0004). In FTWC subgroup, Z-score was lower than that of the other two subgroups (P < 0.009). Vitamin D values were significantly lower compared with those in the general healthy population (vitamin D spina bifida group: 14.6 ± 8.7 mg/dL; normal subjects: 35 ± 9.8 mg/dL; P < 0.001). Subjects with spina bifida showed hypophosphatemia (<3 mg/dL) because of the lower levels of vitamin D (3.1 ± 0.9 mg/dL; P < 0.001). CONCLUSIONS: Spina bifida patients showed lower BMD, vitamin D, and electrolyte values than the healthy population; hence, they have an increase risk of developing pathological fractures. Vitamin D supplementation for a longer time period could reduce this risk.

Nerve Growth Factor (NGF) up-regulation in the cerebrospinal fluid of newborns with myelomeningocele.

BACKGROUND: Neurotrophic factors, such as Nerve Growth Factor (NGF), play a key role in the stimulation of sprouting, synaptic plasticity, and reorganization after spinal cord damage. AIM: The aim of this study was to investigate the expression of nerve growth factor (NGF) in the cerebrospinal fluid (CSF) of newborns with myelomeningocele (MMC) and to determine its correlation with this spinal malformation. PATIENTS AND METHODS: To measure the expression of NGF, we collected CSF samples of 14 newborns with MMC taken immediately before the neurosurgical correction of the spinal malformation and of 14 matched controls. Endogenous NGF levels were quantified using a two-site immuno-enzymatic assay. The statistical analysis was performed using the Mann-Whitney two-tailed two-sample test. RESULTS: In the CSF of patients with MMC, NGF levels showed a significant increase compared to the mean levels of the control group (63.05 ± 7.3 vs 18.32 ± 4.5 pg/mL; (p < 0.001). No correlation was found between NGF expression and different types of MMC malformation, such as the level of spinal lesion and the association with Chiari II syndrome. CONCLUSIONS: Our study shows an over-expression of NGF in the CSF of newborns with MMC. The observed pattern of NGF up-regulation in this subset of patients may stimulate axonal sprouting and synaptic reorganization of the damaged neural cells at the site of spinal cord injury, thereby representing an important biochemical marker of spinal cord damage in MMC patients.

The prevalence of small intestinal bacterial overgrowth and methane production in patients with myelomeningocele and constipation.

STUDY DESIGN: Prospective study. OBJECTIVES: The objective of this study was to assess the prevalence of small intestinal bacterial overgrowth (SIBO), methane (CH4) production and orocecal transit time (OCTT) in children affected by myelomeningocele. SETTING: This study was conducted at the Catholic University in Rome, Italy. METHODS: Eighteen (6M/12F; 16.4±7.6 years) children affected by myelomeningocele were enrolled. All subjects underwent H2/CH4 lactulose breath tests to assess SIBO and OCTT. All patients performed a visual analog scale to investigate abdominal pain, bloating and flatulence, and maintained a diary of the frequency and consistency of the stool during the previous 7 days. A nephro-urological clinical evaluation of the number of urinary tract infections (UTIs) and neurogenic bowel disease score were also performed. RESULTS: Thirty-nine percent (7/18) of the children showed SIBO and 61% (11/18) presented a delayed OCTT. Moreover 44.4% (8/18) produced high levels of CH4. Interestingly, all myelomeningocele children who produced CH4 showed a delayed OCTT and a higher incidence of UTI, with a lower frequency of evacuation, compared with those with a normal or accelerated OCTT. CONCLUSION: The association between CH4 and constipation suggests that CH4 has an active role in the development of constipation. One of the most interesting features of our study is to identify a correlation between myelomeningocele, CH4, delayed OCTT and UTI. The intestinal decontamination with locally acting drugs in these children may reduce the number of UTIs and improve intestinal motility.

Treatment of pressure sores in spina bifida patients with calcium alginate and foam dressings.

STUDY DESIGN: Prospective study on local treatment of pressure sores using calcium alginate and foam dressings in spina bifida patients. OBJECTIVE: Investigate if this sequential approach is valid and safe for selected patients with neurological impairments. MATERIALS AND METHODS: Using European Pressure Ulcer Grading System, after clinical evaluation of local sore, selected patients of Spina Bifida Center of Rome were treated with sequential calcium alginate and foam dressings for 12 weeks. Pressure ulcere surfaces were measured monthly by ulcer tracing. The endpoints were the mean absolute areas surface reduction during every month and number of patients achieving a 50% or more during study. RESULTS: 14 patients (7 males aged 12-24 years) with spina bifida and pressure sores were treated. Mean and standard deviation of mean surface area reduction were 12.5 ± 7.5 cm 2 at start of the study versus 3.7 ± 5.2 cm 2 after 12 weeks, p < 0.001. 75% of the patients reached mean surface area reduction of 50% during trial. Dressing tolerance was good in every patient. CONCLUSIONS: Calcium alginate and foam dressings are valid and safe approach in the treatment of pressure sores in selected patients with spina bifida. In fact, they protect the wound and create an environment favorable to healing.

Post-natal ultrasound morpho-dynamic evaluation of mild fetal hydronephrosis: a new management.

BACKGROUND: Fetal hydronephrosis is the most common anomaly detected on antenatal ultrasound examination, affecting 1-5% pregnancies. AIM: A new management in mild antenatal renal pelvis dilatation (ARPD), using a technique based on both morphological and dynamical evaluation. MATERIALS AND METHODS: Prospective study conducted during a 36-months period in 180 consecutive newborns referred as having mild ARPD. Examinations consisted in a morphological ultra-sound (US) scan evaluating antero-posterior diameter, renal parenchyma, ureteral evidence and pelvis morphology and, subsequently, a dynamic evaluation to analyze any change of the urinary tract during bladder voiding. All children were evaluated both at 3rd day and 1 month after birth. They were divided among those with negative examinations and those with at least one positive scan, trying to discriminate within the latter, children suspected for transient pyelectasis from those suspected for organic pathology. RESULTS: 108 patients had normal US findings both at birth and at 1 month. The remaining 72 babies had at least one abnormal US examination: 54 were suspected for transient pyelectasis, while 18 suspected for organic pathology. At the end of the study, 61 babies (33.9%) had final diagnosis of transient pyelectasis and 11 cases (6.1%) of organic pathology. At one month the dynamic pattern of US findings had the highest negative predictive value, while renal parenchyma evaluation has the highest accuracy. CONCLUSIONS: a dynamic US approach allowed to better select among infants suspected for transient pyelectasis from those suspected for organic pathology, avoiding unnecessary and invasive examinations in healthy babies.

Transanal irrigation in myelomeningocele children: an alternative, safe and valid approach for neurogenic constipation.

STUDY DESIGN: A total of 60 children with myelomeningocele referred to Spina Bifida Center of Rome (31 boys and 29 girls; aged 8-17 years) were treated with transanal irrigation for three months. OBJECTIVE: To investigate whether transanal irrigation is a valid and alternative approach for neurogenic constipation in children with myelomeningocele. METHODS: A questionnaire on bowel disturbances, quality of life and side effects was completed before the beginning and at the termination of the study. SETTING: Italy. RESULTS: About 60% (36/60) of patients reported relief from constipation and 75% (12/16) for fecal incontinence. Wheelchair-bound and walking patients showed same high improvement of bowel habit. Mean (s.d.) scores before and after the study were: neurogenic bowel dysfunction total score: 17.5 (5.2) versus 8.5 (4.3) (P<0.001); digital stimulation of anorectum: 4.2 (2.8) versus 1.3 (2.5) (P<0.01); frequency of fecal incontinence: 5.5 (1.2) versus 1.3 (1.7) (P<0.01) and degree of general satisfaction: 3.0 (2.4) versus 7.7 (1.5) (P<0.001).We observed a reduction of urinary tract infections during the course of treatment: 14 total urinary tract infections (9 caused by Escherichia coli) before versus 6 (3) during treatment (P<0.01). CONCLUSION: Transanal irrigation in children with myelomeningocele is an alternative and relatively safe approach for managing neurogenic constipation; in fact, it improves bowel disturbances, quality of life and seems to reduce the risk of urinary tract infections.

Bone mineral density and body composition in a myelomeningocele children population: effects of walking ability and sport activity.

Myelomeningocele causes serious locomotor disability, osteoporosis and pathologic fractures. The aim of this study was to investigate the relationship between body composition, bone mineral density, walking ability and sport activity in myelomeningocele children. 60 patients aged between 5 and 14 yrs with myelomeningocele (22 ambulatory and 38 non-ambulatory), were studied. Fat mass and fat-free-mass were calculated by anthropometry. The bone mineral density at lumbar and femoral neck were evaluated. Bone mineral density at the lumbar and femoral neck was lower than in the normal population. In the non-ambulaty group, bone mineral density was approximately 1 SD lower than in the ambulatory one (p < 0.01). Fat mass was greater than expected but without significantly differences between walking group (mean 26%) and wheel-chair users (25%). Patients practised sport activity had a better bone mineral density and body fat compared with other patients with the same disability. Patients with myelomeningocele have decreased bone mineral density and are at higher risk of pathologic bone fractures. All subjects showed an excess of fat as percentage of body weight and are shorter than normal children. The measurement of bone mineral density may help to identify those patients at greatest risk of suffering of multiple fractures. Walk ability and sport activity, associated with the development of muscle mass, are important factors in promoting bone and body growth, to reduce the risk of obesity and of pathological fractures.

Acute cholestasis: atypical onset of Kawasaki disease.

Atypical onset of Kawasaki disease (KD) is a frequent problem leading to diagnostic mistake. Acute cholestasis and liver involvement occur occasionally as minor manifestation of KD. We report the case of a 6-year-old boy presenting fever, jaundice, abdominal pain, and ascites who subsequently developed typical KD clinical pattern just at the same time of echocardiographic coronary arteries anomalies. Abdominal radiological evaluation was normal and seroimmunologic markers resulted negative. Shortly after intravenous immunoglobulin and acetylsalicylic acid administration the clinical features disappeared. KD should be considered in differential diagnosis in children with cholestasis, abdominal pain and fever of unknown etiology.

Neurotrophic factor expression in newborns with myelomeningocele: preliminary data.

BACKGROUND: Neurotrophic factors play a crucial role in the stimulation of sprouting, synaptic plasticity and reorganization after spinal cord damage. The aim of this study was to investigate the expression of some neurotrophic factors [brain derived neurotrophic factor (BDNF), glial derived neurotrophic factor (GDNF), and nerve growth factor (NGF)] in the cerebrospinal fluid (CSF) of newborns with myelomeningocele (MMC) and to determine their correlations with this malformation. METHODS: To measure the expression of BDNF, GDNF, and NGF, we collected CSF samples of six newborns during the neurosurgical operation to correct the open MMC and of 10 matched controls. Endogenous neurotrophic factor levels were quantified using a two-site immuno-enzymatic assay. The statistical analysis was performed using the Mann-Whitney two-tailed two-sample test. FINDINGS: In the CSF of patients analysis of neurotrophic factor expression showed a significant increase of BDNF, GDNF, and NGF compared to the mean level of the control group (445.8+/-82.3, 86.5+/-2.6, and 59.9+/-6.2 pg/mL, respectively, respect to 10.2+/-5.9, 19.9+/-11.3, and 15.3+/-2.6 pg/mL) (p<0.001). INTERPRETATION: Our study shows an over-expression of neurotrophic factors in the CSF of newborns with MMC. This neurotrophin up-regulation may stimulate axonal sprouting and synaptic reorganization of the damaged neural cells at the site of spinal cord lesion. The neurotrophic factor up-regulation may represent a particularly important biochemical markers of spinal cord damage and might be associated with the severity of spine injury in MMC patients.

Prevalence of latex allergy in spina bifida: genetic and environmental risk factors.

AIM 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.

Multidimensional study on quality of life in children with type 1 diabetes.

AIM: To study the Health Related Quality of Life (HRQoL) and metabolic assessment in 33 children affected with type 1 diabetes (18 males, 15 females; mean age 10.3 years). METHODS AND RESULTS: We used the Child Health Questionnaire-Parental Form 50 items (CHQ-PF50), measurements of metabolic control and we related them to patient management and family status. Quality of life (QoL) in diabetic children was worse than in the healthy sample. Interestingly, mean and last glycosylated hemoglobin (mean HbAlc r: -.4410 p < .01 and last HbAlc r: -.4012 p < .01), age of patients (r: -.4428; p < .009) and number of glycaemia controls (r: -.37, p < .03) were the most important parameters related to HRQoL parameters. CONCLUSION: This multidimensional study stressed that HRQoL is influenced by the metabolic assessment. Moreover, the report examined the parental perception of QoL in children with chronic diseases. Higher number of glycaemia controls/day, better metabolic control, lower age of children and earlier onset of diabetes produced better physical and psychological aspects of QoL. In comparison with adolescent patients, in children with diabetes, factors as number of insulin injections and daily snacks, and the level of education of the mother were not so important to influence QoL. Unexpectedly, in this sample, life habits, family features, and anthropometric parameters did not correlate with specific domains of QoL.

Urodynamic evaluation in children with lipomeningocele: timing for neurosurgery, spinal cord tethering and followup.

PURPOSE: We assessed the usefulness of urodynamic testing for determining the optimal timing of surgery and for evaluating the development of bladder function in children with lipomeningocele. MATERIALS AND METHODS: We retrospectively evaluated 64 patients (40 females) 3 to 17 years old (mean 8.5) with lipomeningocele. Patients were divided into 3 groups based on age at surgery, ie younger than 12 months (34 patients), 12 to 36 months (17) and older than 36 months (13). All patients underwent urodynamic testing preoperatively and during extended followup (mean 6.5 years, range 3 to 12). RESULTS: Bladder capacity and mean detrusor leak pressure improved in all groups but particularly in patients operated on within the first year of life. At the end of the study mean bladder capacity was 420 cc in patients younger than 12 months, 300 cc in those 12 to 36 months old and 260 cc in those older than 36 months (p <0.01), and mean detrusor leak pressure was 37, 54 and 55 cm H(2)O, respectively (p <0.01). At the latest followup 65% of patients in the youngest group had improved urodynamic parameters vs 33% of those 12 to 36 months old and 28% of those older than 36 months. CONCLUSIONS: Urodynamic evaluation and the presence of neurological impairment have crucial roles in determining the optimal timing of surgery in patients with lipomeningocele, and in diagnosing the onset of tethered cord. Our data show that early surgical repair seems to reduce the risk of neurological deterioration of the lower urinary tract, and allows a more physiological development of urinary function.

Loperamide cause of prolonged urinary retention after acute gastroenteritis.

UNLABELLED: Urinary retention is uncommon in children and only one case has been described in literature with loperamide treatment. We report the occurrence of prolonged urinary retention in a 10-years-old girl after receiving oral loperamide for an acute gastroenteritis. The first episode of urinary retention lasted for 24 hours; radiological evaluation (Magnetic Resonance, cistography and renal ultrasound) did not find abnormality; it was necessary deplete bladder with catheterism. Previous to the gastroenteritis, diuresis has always been regular and she did not suffer for any neurological or urinary problems. Patient was submitted to, without success, percutaneous posterior tibial nerve stimulation (SANS) and recovered after one year clean intermittent catheterization. CONCLUSION: In a period of increasing popularity of self-medical therapy for common children's diseases, paediatricians should be aware of the potential, rare and chronic effects of this type of treatment. Moreover our case suggests that reaction to loperamide should be added to the etiological list of prolonged urinary retention in young patients.

Bone mineral density in survivors of childhood brain tumours.

BACKGROUND: Osteopenia has been reported in children surviving acute lymphoblastic leukaemia, apparently as consequence of therapy. Few studies have been published on bone mineral density (BMD) evaluation in children surviving from brain tumours. The endocrine system in these patients is frequently affected as consequence of therapeutic interventions such as cranial irradiation and anti-neoplastic agents: growth hormone deficiency is the most common adverse sequel. The pathogenesis of osteopenia in brain cancer survivors is multi-factorial but still uncertain. OBJECTIVE: The aim of this study is to examine bone mass in 12 brain cancer survivors and its relationship with their hormonal status. RESULTS AND DISCUSSION: We observed that most of the patients had a BMD that was lower than normal in both the lumbar column and in the femoral neck. Bone mass loss was higher in the lumbar region rather than in the femoral neck, due to spinal radiation therapy and to the effect of hormonal deficiencies. Particularly hypogonadism, but also multiple hormonal deficiencies, are associated with lower BMD values. Experience in clinical care of these patients suggests the importance of periodic evaluations of BMD, especially in those with secondary hormone deficiencies. Moreover, the periodic assessment of the hypothalamus-pituitary function is essential for an early diagnosis of hormonal insufficiency, primarily hypogonadism, to precociously detect bone mineral loss and to prevent pathological fractures, thus improving the quality of life.
