[Use of new elastomeric pumps and PCA in postoperative pain control in thoraco-abdominal surgery]. / Impiego di nuove pompe elastometriche e della PCA nel controllo del dolore post-operatorio in chirurgia toraco-addominale.

36 patients submitted to interventions for thoraco-abdominal surgery has been submitted to antalgic post-operatory therapy with elastomeric pump at a continuous intravenous infusion and patient controlled analgesia (PCA). The patients have been randomized in three groups. The patients of the 1 degree group received 30 minutes before of the end of the surgical intervention 30 mg of Ketorolac. At the end of the anesthesia came started an infusion of 150 mg of Ketorolac (5 vials) in 60 ml of isotonic chlorinated solution at the rate of 0.5 ml/h. The pump had besides the capability of disperse a maximum of 4 bolus/ h, everyone of 0.5 ml, on demand of the patient. The 2 degrees group received a solution containing 60 ml of Morphine in 60 ml of isotonic chlorinated solution with the same formality of administration. The 3 degrees group (placebo) received 60 ml of isotonic chlorinated solution in pumps from infusion and Ketorolac intramuscular on demand. To the times T0 (awakening), T1 (3 h), T2 (6h), T3 (12 h), T4 (24 h), T5 (30 h, was collected algometrical consequences according to VAS (Visual Analogous Scale of Sc modification of the PA increase, FC, FR, SatO2.. The obtained results have highlighted like in the 1 degree group, to the 1 degree algometric consequence (T0), there is a good sedative effect on the pain (intensity of the middle low pain 3.70 +/- 1.64); this antalgic effect has also continued in the other consequences effected in the post-operatory. In the 2 degree group to the awakening (T0), the pain was middle-tall (5.50 +/- 2.32) and an expressive reduction appeared at the time T2 (3.60 +/- 1.35 P < 0.005). In the 3 degrees group have not recorded a diminution of the pain if not after 24 hours from the end of the intervention deposit the intramuscular antalgic therapy. In conclusion, the system infusion + PCA represents an indubitable advantage in comparison with the traditional antalgic therapy as for concern the entity of the reduction of the pain as because it permits the use of a smaller quality of drugs.

[Risk factors present in the recreation areas of nursery schools]. / Indagine sui fattori di rischio presenti nelle aree ricreative delle scuole materne.

In order to evaluate the playground risk factors, 45 nursery schools of a USL were investigated. The results show that the risk factors depend mostly on inadequacy of the playground equipment and of its installation and maintenance. Moreover the playground surfaces are frequently nonelastic and the first-aid kits insufficient. Pediatricians have a key position in scholastic accident prevention.

Rare syndromes. The Kaufman-McKusick syndrome. A review of the 44 cases reported in the literature.

The Kaufman-McKusick syndrome (MK 23670) is a rare autosomal recessive disorder characterized by the triad of hydrometrocolpos, postaxial polydactyly, and congenital heart disease. Multiple other anomalies have been ascribed to this syndrome. Hydrometrocolpos, especially if unrecognized, may be a serious, life-threatening condition in the newborn girl. Forty-four cases have been so far reported in the literature. A great phenotypic variability occurs in this syndrome, therefore making it very difficult to identify the disorder at its presentation and classify it correctly. We shall hereafter review current data regarding the prominent clinical features, the diagnosis and treatment of this syndrome. Problems in genetic counseling will be discussed.

Chronic diarrhea due to cow's milk allergy. A 4- to 10-year follow-up study.

There is general agreement that chronic diarrhea due to cow's milk allergy (CMA) resolves with a cow's milk-free diet, and that tolerance to cow's milk is achieved by 2 years of life. We have followed for 4 to 10 years, 41 infants with chronic diarrhea due to CMA, who had at onset of diarrhea RAST and/or skin tests positive to cow's milk. After the diarrhea subsided, the diet was continued for 6 months and, subsequently, cow's milk reintroduction was attempted at 6-month intervals. In contrast to 25/37 children (four cases were lost to follow-up) in whom CMA subsided at a median age of 2 years, 12/37 (32.5%) children did not tolerate cow's milk at a median age of 6 years. In addition, a large proportion of children (27/37 = 73%) suffered during the follow-up period from other atopic manifestations, due either to CMA or to inhalant allergy. Our data suggest that in infants with chronic diarrhea due to CMA, RAST and/or skin tests positive to cow's milk may indicate either the tendency of CMA to persist throughout childhood, or the risk of developing other atopic diseases.

Comparative evaluation of the cardiorespiratory effects of assist control ventilation vs pressure support ventilation in patients following orthotopic liver transplantation.

OBJECTIVE: 1) To compare the haemodynamic tolerance of ACV and PSV in patients mechanically ventilated after orthotopic liver transplantation; 2) to compare patients comfort during ACV and PSV. DESIGN: Prospective randomized cross-over study. SETTING: General ICU of the University of Rome "La Sapienza". PATIENTS: Eighteen patients admitted in ICU after orthotopic liver transplantation. MEASUREMENT AND RESULTS: Haemodynamic, oxygen transport and blood gas data were compared during an ACV and PSV trial (30'). A statistically significant decrease of mean pulmonary and systemic arterial pressure, PCOP, LVSWI, occurred during the PSV trial. PaO2 and DO2I decreased during PSV, but were still in supranormal range; 16 out of 18 patients described PSV as more comfortable. CONCLUSIONS: ACV and PSV provided a comparable haemodynamic tolerance in our patients, although during PSV the PaO2 was slightly decreased, probably due to decreased mean airway pressure (from 9.3 +/- 1.2 cmH2O during ACV to 6.6 +/- 1 cmH2O during PSV). PSV can be considered as a good alternative to the standard weaning techniques following orthotopic liver transplantation.
