Chylothorax is the accumulation of chyle in the pleural space. In newborns the congenital form is often prenatal diagnosed, while the late variety originates to damage to the thoracic duct by cardiac surgery, diaphragmatic hernia, etc. Clinical presentation results from the accumulation of pleural fluid and the symptoms depends on the size of the effusion. The treatment needs both medical and surgical care. The pleural cavity should be drained via thoracocentesis, and total parenteral nutrition should be started. Afterward fat-free diet with the addition of medium-chain triglycerides could be initiate. Somatostatin and octreotide have been successfully employed, mainly in post-surgery chylothorax. Surgery should be considered when medical management fails. Some approaches are reported, and thoracic duct ligation, pleurodesis and pleuroperitoneal shunts are the most utilized. The prognosis of chylothorax depends on the etiology, and it is consequence of a variety of treatments that may influence the outcome.

The authors evaluate the use of data supplied by common systems used to calculate respiratory mechanics in newborns in order to analyse the impact on the management of patients requiring assisted ventilation. Over the past few years, the sale of respiratory monitors that are easier to use and less complicated to manage, as well as being less expensive, has meant that nearly every Neonatal ICU can now determine, in real time, both the causes of respiratory insufficiency and the conditions of the newborn lung during mechanical ventilation to ensure improved adaptation of ventilatory support. Leaving aside a discussion of respiratory physiopathology and the principles regulating pulmonary ventilation, the authors focus on the practical effect that data normally supplied by this type of apparatus (airway pressure, inspiration and expiration airflow, expiration minute volume calculated for each respiratory act, tidal volume, system leaks and dynamic compliance) have on the ventilatory "setting" chosen by the clinician or on the diagnosis of some commonly found situations during neonatal mechanical ventilation. The experience described concerns the impression of clinicians, skilled in the management of patients receiving conventional artificial ventilation but not so attracted by respiratory physiopathology, regarding the value of such instruments. The unanimous positive opinion confirms the thesis whereby respiratory monitoring can certainly help the neonatologist make a real time evaluation of both the causes leading to respiratory failure and the effect on the lung of any therapeutic decisions.

Background: The preparation of a PN (parenteral nutrition) solution in neonatal and paediatric Departments is an operation of both critical importance and great difficulty (need of time to do it; complex calculations in order, for example, to subtract takes of nutrients from other sources; etc.)., Materials and Methods: With the aim to speed such a proceeding, the authors (from a 1000 deliveries/year NICU) developed a computerised system for the preparation of PN mixtures, based on a common and easily available "spreadsheet"., Results: The results of its application on a population of preterm babies in which parenteral and enteral (minimal enteral nutrition etc.) feedings were contemporarily provided, are illustrated. Advantages by using this software are the lower cost if compared with other dedicated softwares on sale and its great simplicity and versatility. The program is easy to use eve if different feeding plans are required; the data obtained at the end of the study demonstrated the effectiveness of the software in correctly calculate food components dosages., Conclusions: Using producer's data on feedings composition and up-to-date parenteral nutrition schedules, a reliable composition of the obtained PN mixtures was eventually achieved, as demonstrated by growth and blood samples.

A case of Henoch-Schönlein purpura (HSP) characterized by several unusual complications and exceedingly prolonged course is reported. A 6-year-old boy, hospitalized with a typical clinical picture of HSP, developed after a few days a severe gastrointestinal vasculitis leading to digestive hemorrhages and food intolerance. The treatment included continuous gastrointestinal infusion, parenteral nutrition, and corticosteroids during the exacerbations of symptoms. Intestinal ultrasonography showed diffuse submucous edema and widespread mural hematomas; hydrops of the gallbladder and edematous swelling of the pancreas were also detected. A gastro-duodenoscopy revealed diffuse and severe mucosal vasculitis with ulcers and petechial lesions. One week after admission the occurrence of weight gain, hyponatremia, and hypoprotidemia in the absence of proteinuria suggested a protein-losing enteropathy. The elevation of serum and urine amylases was consistent with pancreatic involvement. The course was characterized by recurrent exacerbations of gastrointestinal manifestations; symptoms subsided slowly to such a degree that oral feeding could be gradually restarted only seven weeks after admission. The use of high-frequency intestinal ultrasonography proved useful and sensitive in monitoring the evolution of intestinal involvement. During hospitalization the child complained of acute painful scrotal swelling. Ultrasonography showed scrotal hemorrhage and testicular swelling but no signs of testicular torsion, thus helping to avoid surgical exploration. In the recovery phase the child complained of colicky abdominal pain with vomiting. A plain abdominal roentgenogram showed bilateral staghorn pelvic urolithiasis. This finding was confirmed by an intravenous pyelography which also revealed a bilateral pyeloureteritis with edema of the ureteral wall and partial stenosis of the lumen.(ABSTRACT TRUNCATED AT 250 WORDS)
