RESUMO
Cutis Marmorata Telangiectatica Congenita (CMTC) is a rare, sporadic condition usually present at birth characterized by localized or generalized persistent cutis marmorata, telangiectasia and phlebectasia. We report a preterm female newborn, the third child of non-related caucasian parents, with CMTC at birth who showed typical cutaneous features and monolateral congenital glaucoma. The pathogenesis of this disorder is unknown and the cause is probably multifactorial. Teratogens and autosomal dominant mode of inheritance with incomplete penetrance have been considered as etiological factors. Prognosis, in uncomplicated cases, is good.

Pasteurella multocida is normally present in respiratory and digestive tract of many domestic and wild animals, but is a rare pathogen in neonatal infection. Here we describe for the first time a case of meningitis complicated by status epilepticus and right parietal lobe cerebritis. The patient showed a dramatic clinical onset characterized by septic appearance and prolonged seizures. Multidrug anticonvulsivant therapy was used to control the status epilepticus, but despite the aggressive treatment electrical crises were still evident 24 hours after the admission. Furthermore, a brain MRI, performed to investigate a persistent intermittent fever even if CSF became sterile, showed a focus cerebritis in the right parietal lobe, early stage of the cerebral abscess. Prolonged antibiotic therapy with steroids was requested to solve the cerebritis area. Interestingly, direct contact between the patient and domestic animals was denied by the family, but the father reported a contact with a rooster, killed and cooked few days before, suggesting, as previously described, that Pasteurella may also be transmitted through asymptomatic human carrier. The patient had a favourable outcome with no medium-term sequelae one month after discharge, but the severity of the clinical course and the unpredictable way of transmission highlight the importance of hygiene measures approaching infants.

Therapeutic hypothermia (whole body or selective head cooling) is becoming standard of care for brain injury in infants with perinatal hypoxic ischemic encephalopathy (HIE). Brain cooling reduces the rate of apoptosis and early necrosis, reduces cerebral metabolic rate and the release of nitric oxide and free radicals. Animal models of perinatal brain injury show histological and functional improvement due to of early hypothermia. The brain protection depends on the temperature and time delay between insult and beginning of treatment (more effective with cooling to 33 +/- 0.5 degrees C, and less than 6 hours after hypoxic-ischemic insult). Recent meta-analyses and systematic reviews in human neonates show reduction in mortality and long-term neurodevelopmental disability at 12-24 months of age, with more favourable effects in the less severe forms of HIE. The authors describe their experience in 53 term newborns with moderate-severe HIE treated with whole body cooling between 2001 and 2009, and studied with magnetic resonance imaging (MRI) and general movements (GMs) assessment. The creation of a network connecting the Neonatal Intensive Care Unit with the level I-II hospitals of the reference area, as part of regional network, is of paramount importance to enroll potential candidates and to start therapeutic hypothermia within optimal time window.

The frequency of early-onset neonatal sepsis without prophylaxis is 1-5/1.000 live births. Since year '70 the most frequent causative microorganism is the group B Streptococcus (S. agalactiae, GBS), followed by Escherichia coli. The mortality rate is now reduced to 4% due to the improvement of neonatal intensive care. In the USA, the incidence of GBS early-onset neonatal sepsis has been markedly reduced by the application of the guidelines released by the Centers for Disease Control (CDC). This strategy, however, is not effective on occurrence of late-onset neonatal group B streptococcal disease. In Italy, the application of CDC guidelines is not customary, and different, often complex, protocols of obstetrical-neonatological integrated approach are applied. The frequency of infectious risk has made the GBS a paramount problem for the neonatologist, even for the legal responsibility issues resulting from the multiplicity of possible options. To reach the best level of protection of the newborn against early-onset GBS infection, the working group of providers of prenatal, obstetric, and neonatal care of the functional area of Cuneo issued an integrated protocol, in order to perform the GBS screening with the optimal culture method suggested by CDC guidelines in the highest possible number of pregnant women, and to standardize the obstetrical and neonatal management.

We attempted to verify in a group of 101 children with first urinary tract infection whether it was possible to identify groups of patients with different risks of developing renal scarring by taking into account both the extent of kidney involvement documented in the acute phase of infection using a dimercaptosuccinic acid (DMSA) scan, and the presence or absence of vesicoureteral reflux (VUR). The frequency of persistent lesions in kidneys with mild-moderate lesions (less than 50% of kidney involvement) in the presence of VUR or in non-refluxing kidneys was similar (P=0.1447), while the frequency of persistent lesions in kidneys with severe lesions in the presence of VUR was significantly higher than the frequency of persistent lesions in non-refluxing kidneys (P=0.0089). The extent of kidney involvement and the presence of VUR make possible the identification of different categories of risk of scarring: in the "low risk group" (normal kidney with/without VUR) the risk of scarring is 0%; in the "intermediate risk group" (mild lesions with/without VUR; extensive lesions without VUR) the risk of scarring is between 14% and 38%, while in the "high risk group" (extensive lesions with VUR) the risk of scarring is 88%. Quantifying the risk of scarring could help in planning the treatment or in modifying the later strategy.

This prospective study, performed in 101 children with a first symptomatic urinary tract infection (UTI), evaluates the diagnostic value of clinical, biological, and ultrasound parameters in detecting children with acute renal infection documented by dimercaptosuccinic acid (DMSA) scintigraphy. In children with a positive DMSA scan, mean C-reactive protein (CRP) was higher than in children with a normal DMSA scan (114+/-64 vs. 67+/-38 mg/dl, mean+/-SD, P=0.0002). The sensitivity and specificity of CRP was 64% and 68%, respectively. In children with severe kidney involvement, mean CRP and white blood count (WBC) were higher than in children with mild/moderate disease (151+/-83 vs. 92+/-55 mg/dl for CRP, P=0.0149; 20,100+/-6,854 vs. 15,023+/-6,145 WBC/ mm3 for WBC, P=0.0131). The sensitivity and specificity was 85% and 20% for CRP, and 77% and 18% for WBC, respectively. One or more areas of abnormal cortical echogenicity were documented in 3% of kidneys with positive DMSA scans. Dilatation of the collecting system was observed in 24% of kidneys. The sensitivity and specificity of ultrasonography was 27% and 89%, respectively. In conclusion, clinical, biological, and ultrasound parameters do not accurately distinguish cystitis from pyelonephritis in children with UTI and do not identify children with severe renal damage. Accordingly, we recommend that DMSA scan should be added to the initial work-up of children with UTI.
