[Neonatal characteristics in the physiopathology of shock]. / Peculiarità neonatali nella fisiopatologia dello shock.

In this work we tried to analyse the different factors which cooperate to produce and maintain a shock condition; we considered in particular pathophysiology and haemodynamic features of the different types of shock and the pathophysiology of MOSF (multiple systems organ failure). Furthermore, we remembered peculiarities and effects of the "reperfusion syndrome" which can occur after cardiopulmonary resuscitation of the patient due to superoxides. Finally we outlined the substantial and significant differences between newborn and not newborn concerning the haemodynamic responses and the cardiocirculatory management in the newborn during shock treatment.

[Apple peel small bowel: surgical correction and post-operative treatment]. / Apple peel small bowel: correzione chirurgica e trattamento post-operatorio.

The authors describe 6 cases of Apple Peel Small Bowel observed in the last ten year experience in Institute G. Gaslini of Genoa, Italy. They make a precision on early diagnosis and on surgical treatment, which is original, and also on post-operatory medical treatment. The importance of making an optimal nutritional support with total and partial parenteral nutrition for long time is of great significance to have a better outcome and psycho-physical development in such patients.

[The clinical assessment and intensive treatment of meningoencephalitis in newborns and children of subsequent ages]. / Valutazione clinica e trattamento intensivo delle meningo-encefaliti in età neonatale e successive età pediatriche.

We focused on the best timing and management when admitting into intensive care unit a pediatric patient with central nervous system infection. The modified scales for pediatric patients did not prove satisfactory and reliable for making such decision. In fact the final score is obtained by adding the partial scores regarding the different clinical aspects. That bears a loss of informations. For this reason we think that the cardiorespiratory and metabolic parameters, assessed in a period of time, may indicate the moment when it is necessary to start an intensive care in these patients, regardless of consciousness. We therefore discussed the monitoring precociously required in these patients after assessing the initial clinical status. We also discussed the intensive care procedure employed in severely ill patients with cardio-circulatory and metabolic problems due to septic shock caused by bacterial meningoencephalitis (infants) and meningitis (other pediatric ages). In patients affected by infectious or post-infective encephalitis with respiratory failure and/or brain edema, it is essential to apply the organ protection procedures and particularly neuroprotection.

[Unusual pelvic pathology treated with posterior sagittal anorectoplasty]. / Patologia pelvica rara trattata secondo i principi della PSARP.

Posterior sagittal approach is very useful for the correction of anorectal malformations, but it can be used also for the treatment of pelvic or perineal masses. The authors present 3 patients affected one by a perineal hamartoma, one by a rectal duplication and one by a retrorectal cystic teratoma. All the patients were treated following the PSARP technique, using the Penã's bipolar electro-stimulator just in order to respect all the muscles of the anorectal sphincters. Using this procedure the authors were able to preserve the full anorectal continence in all the 3 patients.

[Role of extracorporeal circulation in reversible acute cardiorespiratory insufficiency in neonatal and pediatric intensive care]. / Ruolo della circolazione extracorporea nell'insufficienza cardiorespiratoria acuta reversibile in terapia intensiva neonatale e pediatrica.

In the present study we try to analyze indications, contra-indication, side effects and limits of the use of extracorporeal circulation in neonatal and pediatric patients affected by reversible acute cardiorespiratory failure. The greatest experience on this technique has been achieved in the neonatal age (about 6000 newborns have been treated until now), while the employment in the pediatric age appears more recent (about 500 patients). Moreover, we focused on the drop-in criteria for neonatal and pediatric patients and on the clinical aspects and laboratory findings which can anticipate the surviving rate; the latter appears in any case much greater in the neonatal patient compared to the other pediatric ages.
