Is vitamin D status known among children living in Northern Italy?

PURPOSE: To assess vitamin D status in children aged 2-220 months in northeastern Italy (latitude 46°). Serum 25-hydroxyvitamin D (25OHD) concentration was assessed in 93 children afferent to the Pediatric Department of the Hospital of Udine. METHODS: Vitamin D status was defined as follows: sufficient with serum 25OHD between 50 and 250 nmol/l (level 4); insufficient between 37.5 and 50 nmol/l (level 3); deficient less than 37.5 nmol/l (level 2); severely deficient if less than 12.5 nmol/l (level 1). We investigated the potential risk factors of vitamin D deficit. RESULTS: We found that six children (6.4%) had level 1, 36 (38.7%) had level 2, 9 (9.7%) had level 3, and only 45.2% had sufficient level of 25OHD. Immigrate children had a higher risk for vitamin D deficiency if compared with Italians: 75% of non-Italian children had an insufficient 25OHD level compared with 47.0% of Italian children (p = 0.0036). There was a marked seasonal effect on 25OHD level: when plasma sample was withdrawn between November and May, only 29.4% of children showed sufficient vitamin D level, while 70.5% was insufficient (p < 0.0001). Among the obese children, 9.0% had sufficient level of 25OHD with 90% being deficient (p = 0.01). We did not find any significant difference in vitamin D status among children in different age groups. CONCLUSION: Vitamin D deficiency is common in children living in northeastern Italy. The risk factors were winter season for blood withdrawal, non-Caucasian race, and obesity. These high-risk groups should be targeted for screening and educated about the need of sunlight exposure.

Radiological treatment of renal artery occlusion after blunt abdominal trauma in a pediatric patient: is it never too late?

A 15-year-old boy was severely injured in a motor vehicle accident. A blunt abdominal trauma resulted in multiple lesions requiring urgent surgical treatment. Seven days after the trauma, renal Doppler sonography showed absence of arterial signal in the left kidney hilum. Selective renal angiography was performed, showing localized aneurysmatic dilatation in the principal branch of the left renal artery with interruption of renal parenchyma blood flow. Stent graft placement resulted in the resumption of a normal perfusion. After long-term follow-up, symmetric renal function has been demonstrated. Our results confirmed the efficacy of endovascular treatment in the management of pediatric patients with renal artery occlusion after blunt abdominal trauma. The outcome appeared excellent even after a prolonged period of renal ischemia.

Homotoxicological remedies versus desmopressin versus placebo in the treatment of enuresis: a randomised, double-blind, controlled trial.

The aim of this trial was to compare the safety and efficacy of homotoxicological remedies versus placebo and versus desmopressin (dDAVP) in the treatment of monosymptomatic nocturnal enuresis (MNE). We conducted a randomised, double-blind, double-dummy, controlled trial in which 151 children with MNE were randomly assigned to receive oral homotoxicological remedies (n = 50), dDAVP (n = 50) or placebo (n = 51). The primary outcomes were: the reduction of wet nights per week after 3 months of therapy; the evaluation of the numbers and percentages of non-responders and responders; the number of children relapsing after initial response and the number of children attaining 14 consecutive dry nights during the treatment. The secondary outcome was the detection of adverse effects. Baseline clinical characteristics were similar in the three groups of patients. After the 3 months of therapy there was a significant difference between the three groups (P < 0.001) in the mean number of wet nights per week. The daily dose of dDAVP produced a statistically significant decrease (62.9%) in wet nights compared to placebo (2.4%) (P < 0.001) and compared to homotoxicological remedies (30.0%) (P < 0.001). There was a significant decrease in wet nights among the group treated with homotoxicological medications if compared with placebo (P < 0.001). The full response achieved with homotoxicological remedies (20%) was superior if compared with placebo (0%) (P < 0.001). Homotoxicology was superior to placebo (P < 0.001) with regard to the number of children attaining 14 consecutive dry nights during treatment. Our study demonstrates that homotoxicology is safe and effective when compared with placebo, even if it is significantly less effective than dDAVP in this clinical condition.

Penile involvement in Henoch-Schönlein purpura with good prognosis.

Henoch-Schönlein purpura (HSP), the commonest vasculitis in children, occurs most frequently between the ages of 4 and 6 years. We report the case of a 3-year-old boy with an otomastoiditis who was treated with cephalosporin and corticosteroids following a typical purpuric skin rash diagnosed as HSP. The patient also developed an acute occurrence of impairment of the glans, prepuce and penis 4 days after recovery that completely disappeared after a further 2 days, with the cutaneous rash subsiding on discharge from hospital.

Increased excretion of glycosaminoglycans in children with urinary incontinence compared to those with monosymptomatic nocturnal enuresis.

OBJECTIVE: To analyse the urinary excretion of glycosaminoglycans (GAGs) in patients with either urinary incontinence or nocturnal enuresis. MATERIAL AND METHODS: The study population comprised 65 patients with either nocturnal enuresis (n=34) or urinary incontinence (n=31) and 67 controls. Excretion of urinary GAGs was assessed using the sodium tetraborate-carbazole method. RESULTS: GAG excretion in patients with urinary incontinence was significantly higher than that in controls (p<0.000129) and in children with nocturnal enuresis (p<0.016). There were no age or sex differences in GAG excretion in the three groups studied. CONCLUSION: Increased GAG excretion in patients with urinary incontinence suggests an association with urothelial/detrusor pathology.

Preliminary data on monosymptomatic nocturnal enuresis in children and adolescents with type 1 diabetes.

OBJECTIVE: To evaluate the prevalence of monosymptomatic nocturnal enuresis (MNE) in a group of children and adolescents prior to the onset of type 1 diabetes (Dt1). MATERIAL AND METHODS: We considered 88 patients with Dt1 with a mean age of 15.2 years over a period of 3 years. All patients were investigated by means of a questionnaire about the occurrence of MNE prior to the onset of Dt1. Each patient had normal urinalysis results, with no glycosuria, a normal urinary flow rate and no day-time symptoms such as urge incontinence or urgency. RESULTS: We found that 24/88 patients (27.2%) were bedwetters before the onset of Dt1. After beginning insulin treatment, 7/24 bedwetters (29.2%) kept presenting MNE. In total, 7 of the initial 88 patients (7.9%) displayed persistent features of MNE. CONCLUSIONS: The occurrence of MNE may overlap with symptoms of Dt1 but requires specific medical attention as a separate entity due to its possible persistence even when Dt1 has been controlled by insulin treatment.
