[Parapneumonic effussion. A review of 33 cases over 6 years].

UNLABELLED: The incidence of empyema thoracis in children seems to be increasing. The objective [corrected] of this study is to propose a rational initial treatment of parapneumonic effusions in order to reduce hospital stay and late-stage empyema complications. Medical records of 33 children presenting parapneumonic effusions who required any surgical therapy between 1997 and 2002 were reviewed. They were grouped as (I) successful management with chest tube, (II) successful management with intrapleural instillation of urokinase and (III) successful surgical treatment: (IIIa) thoracoscopy or (IIIb) thoracotomy. CONCLUSION: Early sonographic evaluation of parapneumonic effusions is usefull to evaluate the severity of disease and the need for surgical intervention. Thoracoscopic-assisted surgery is an effective treatment for pediatric early-stage empyema. Thoracotomy is indicated for most children with established empyema.

[Impact of formation programs in initial management of injured children].

INTRODUCTION: In 1997 we developed the "Pediatric Trauma Life Support Course"applied to every one who provide care for the pediatric trauma patient. Since November 1997 until December 2000, 14 courses were imparted inside of the "Comunidad de Madrid" with total number of 289 students. Thirty-eight students have been people who worked in the prehospital area inside of our Community. The aim of this paper is to determinate the possible impact of these Courses in the prehospital management of the pediatric trauma patient. MATERIAL AND METHODS: We reviewed the Pediatric Trauma Registry inputs of our hospital since January 1995 until December 2000. A total number of 2166 patients required admission in our hospital after the injuries. 495 patients which moved to our Institution by medical people and a special transport (ambulance/medical van) were enrolled. The patients were classified into two groups. In the first group were included the children admitted between 1995 to 1997 (group 1, n = 232), before we had applied our Courses and in the second group, the patients admitted between 1998 to 2000 (group II, n = 263), after The Pediatric Trauma Life Support Course was conducted. Both groups seems to be equal if we compare the age, sex and severity of the injuries. We analysed the infant orotracheal intubation in a coma patient, gastric intubation in the several trauma patient, vascular access and apply a semirigid cervical collar into a head injury. If we think that the application of these manouvers will be a good quality index of the management of these patients in the prehospital area, we compare the index of application of these variables according to the years before and after the Courses were imparted. For this pourpose we used the X2 test shows significant differences within both groups if p < 0.05. RESULTS: All paramethers analyzed were better in group II than in group I (p < 0.05). CONCLUSIONS: The results of this paper shows that the use of this program for the management of the pediatric trauma patient is going well and the assessment is doing better than few years before.

[Events related with injury severity in pediatric multiple trauma].

AIMS: Epidemiological analysis of main factors affecting multiple trauma in children in our environment. METHODS: We reviewed the data collected from the patients (n = 2.166) admitted to our hospital because of trauma and included in our Registry from January 1995 to December 2000. Among this group 79 patients were considered severely injured trauma patients according Injury Severity Score (ISS) (ISS > 15) and selected for the study. Statistical analysis was done using chi2 and Student t test, p values under 0.01 were considered significant. RESULTS: Group gender distribution was 49 males and 30 females, age average was 9.7 years (range 0-15 years) Traffic related injuries were the leading cause of trauma in this group (77,2%). Initial triage by using the Pediatric Trauma Score allowed identifying the injury severity in 73,4% of patients (58 children obtained a PTS < or = 8). In 32,9% of the cases the patient was in coma at admission in the Emergency (Glasgow Coma Scale < or = 8, n = 26). ISS average was 23.4 (range 16-75). Most patients suffered from multiple injuries (87,3%), average of injuries number was 4,7 (range 1-9). The most frequent trauma localization was cranial trauma. Admission in the intensive care unit was necessary in 65,8% of patients, and any kind of surgical procedure was done in 35,4%. Average length of stay was 17,1 days (range 0-214 days). Injury severity was higher in automotive patients without restraining systems (I.S.S. average 27,2, mortality 16,6%). Overall mortality was 11,4% (n = 9), and 94.3% of patients presented any functional or anatomic disability. CONCLUSIONS: Traffic related injuries are the main cause of multiple trauma in children. The severity and high mortality of these injuries make imperative polytonal education systems and the use of restraining devices.

[Hemodynamic changes during laparoscopic surgery. Preliminary study].

The haemodynamic changes produced by laparoscopic surgery in children have been evaluated. A transesophageal echocardiographic study on 13 patients (7 males and 6 females, 10.8 +/- 2.7 years old) has been performed before, during and after peritoneal CO2 gas insufflation. A change on the Doppler waves pattern of the infradiaphragmatic veins along with an increase in blood flow velocity were observed. Pulmonary veins suffered minimal changes showing an increase on either the systolic pressure and on atrial contraction. Diastolic retrograde flow in aorta reflected an increase in peripheral vascular resistance. Cardiac output increased minimally. All haemodynamic changes returned to basal after gas peritoneal desufflation. These data show that laparoscopic surgery could produce important cardiac derangements in children with ventricular dysfunction or in patients presenting left ventricular outlet obstruction. In these patients laparoscopic surgery might be precluded.

[Tissue expansion in the reconstruction of post-burn lesions in childhood].

Tissue expansion has gained increased acceptance in postburn reconstruction. In this study, the clinical outcome in 17 paediatric burn patients is outlined. A total of 46 tissue expanders were inserted for the reconstruction of postburn scalp alopecia (n = 11) and burn scars (n = 6). The average size of soft tissue defect was 124 cm2. Mean followup was 19 months. The overall outcome in most cases was excellent, however, complications were common (37%) and included infection, exposure, port loss, and partial flap necrosis. Five patients in the scalp reconstruction group required transfusion (45%). Tissue expansion in paediatric burn reconstruction is a useful technique which may yield superb results, however, careful surgical planning is essential to avoid complications.

[Post-traumatic cholelithiasis].

A 5 year old patient, without any lithogenic antecedent, suffered a trauma, resulting in a shrunken fracture of the left parietal bone, and a splenic parenchymal hematoma. A hemoperitoneum developed at the 3rd postoperation day, with an overall blood loss of 15% of the total blood volume. At the 6th day a well formed biliary calculi was detected in the gallbladder. As the patient remain asymptomatic related to his cholelithiasis, an ultrasound follow-up was instituted. At 3 month postinjury all biliary stones dissolved completely. In this report, the etiopathogenic factors responsible of stone formation in the biliary tree, and current therapeutic recommendations are reviewed.

[Nuclear magnetic resonance of anorectal malformations and persistent postoperative fecal incontinence].

We review our experience with Magnetic Resonance Imaging (MRI) in the evaluation of 6 patients showing anorectal malformation, and 4 more with persistent postoperative fecal incontinence. Preoperative sagittal, axial and coronal planes were studied with special consideration to the pelvic and vertebral structures. The excellent resolution of MRI allowed accurate identification of the pelvic musculature in all patients, including those with bizarre sacral abnormalities. MRI revealed structural anomalies not detected previously, such as teathering cord, intraspinal lipoma, presacral mass and renal malformation. In our institution, MRI has replaced the CT scan in the study of patients suffering of persistent fecal incontinence. In non operated on cases of anorectal malformations, MRI determines with extraordinary accuracy the location of the rectal atretic pouch, the actual pelvic muscular quality, and the detection of previously unsuspected associated anomalies.

[Pyknodysostosis: extreme cause of sleep apnea].

We describe a twentieth month old infant who had a pycnodysostosis syndrome. This malformation shows a loss of the normal mandible angle with generalized bone hyperdensification. The first produced and airway obstruction, with special relevance during sleeping hours. A polysomnography revealed an obstructive sleep apnea syndrome. The respiratory picture deteriorated with worsening of the airway obstruction, hypoxemia and finally pulmonary hypertension and cor pulmonale. A tracheostomy was performed, with resolution of the sleep apnea and pulmonary hypertension. The etiology, pathophysiologic consequences and surgical treatment of obstructive sleep apnea syndrome is reviewed.

[A case of total intestinal aganglionosis. 2 years of survival].

A two-year-old male is presented. Small bowel aganglionosis was proved to extend to 3 cm below ligament of Treitz. Gastrostomy and ileostomy was done. He received his caloric intake by cyclic home parenteral nutrition trough implantable venous system. At eighteen months of age, intestinal transplantation was refused and reoperation was done. The child underwent Ziegler's miotomymiectomy on 60 cm of aganglionic jejunum. Now at twenty seven months of age he receives cyclic parenteral nutrition, and enteral feedings are being increased slowly. The weight/height was at 91 per 100 standard, intestinal motility appears much better on contrast study and he is developmentally a normal child.

[The early diagnosis of intestinal ischemia by gammagraphic study].

Intestinal wall necrosis without perforation was produced in six dogs. Another group of three dogs served as a control. The histologic findings, the degree of ischemia and scintigraphic images obtained after the infusions of autologous white blood cells labelled with indium-111 oxine were correlated. Positive scans were obtained in all the dogs with proven intestinal ischemia. Negative scans appeared in the dogs without ischemic insult and a false-positive scan were observed in a control dog with diarrhea.

[Sepsis in children using venous implants with reservoir].

Sepsis is a serious situation in patients with chronic central venous access. The infections complications presented with totally implanted reservoirs are studied in this paper. Twenty five venous systems for chemotherapy, total parenteral nutrition, specific drugs and blood drawing, were placed in 24 patients ranging in age from three months to sixteen years. Catheter related sepsis was defined as simultaneous positive blood cultures drawn through the reservoir and peripheral vein. Five children (20 per 100) had septicemia with candida albicans (3), staphylococcus aureus (1) and staphylococcus epidermidis (1). Four systems was removed after unsuccessful antimicrobial therapy. Three symptomatic patients were studied by echocardiography, one of them showed thrombosis in superior vena cava and right atrium, this child underwent an open atriotomy. These data suggest that removal of implantable venous system is required for successful treatment in patients with catheter related sepsis.
