RESUMO
Diarrhoea remains a common cause of illness in Guatemala, with children suffering most frequently from the disease. This study directly compared the frequency, enterotoxin, and colonization factor (CF) profiles of enterotoxigenic Escherichia coli (ETEC) strains isolated from children living in a rural community in Guatemala and from Western visitors to the same location during the same seasons, using similar detection methodologies. We found that ETEC accounted for 26% of severe cases of diarrhoea in children requiring hospitalization, 15% of diarrhoea in the community, and 29% of travellers' diarrhoea in visitors staying ⩾2 weeks. The toxin and CF patterns of the ETEC strains isolated from both groups differed significantly (P < 0·0005) as determined by χ 2 = 60·39 for CFs and χ 2 = 35 for toxins, while ETEC phenotypes found in Guatemalan children were comparable to those found in children from other areas of the world.

AIM: To present our experience in the management of three cases of tracheobronchial iatrogenic injuries and the literature revision about this pathology. MATERIAL AND METHODS: We present 3 patients treated in our center with tracehobronchial iatrogenic injuries since 2005. RESULTS: Case 1. 8 year old boy who present cervical, mediastinal and facial emphysema after foreign body extraction. After 9 days of conservative management without endotracheal intubation all emphysema remited, and the bronchial injury healed. Case 2. 1 month old toddler who presented after cardiovascular surgery and endotracheal tube extraction dyspnea and hypoxia. Fibrobronchoscopy showed subglotic posterior tracheal disrupture. Fifteen-day endotracheal intubation throughout the injury was enough management on this patient. One month later the tracheal injury was completely healed. Case 3. 5 year old girl with tracheobronchial iatrogenic injury after orotracheal intubation who developed neumothorax and subcutaneous emphysema. After fiteen-day conservative management without intubation the injury healed. CONCLUSION: After iatrogenic tracheobronchial injury suspicion there were confirmed by fibrobronchoscopy. Conservative treatment in this patients was successful. Orotracheal intubation prevented air leaking through the tracheal injury allowing complete healing of the trachea. Bronchial injuries healed without needing intubation or mechanical ventilation. Articles reviewed recommend surgical treatment in those cases who had complete or large airway disrupture or in those who were misdiagnosed.

INTRODUCTION: Palmar hyperhidrosis (PH) is a relative frequent pathology which basically affects patients' life quality limiting social and laboral life. The treatment of choice is thoracoscopic sympathectomy, most frequently done during adulthood. The aim of our study was to evaluate the degree of satisfaction of the pediatric patients treated in our centre. MATERIAL AND METHODS: We retrospectively reviewed the clinical records of the patients controlled and treated in our centre during the last 4 years evaluating the symptoms before surgery, the level of the sympathectomy and postoperative complications. To evaluate the long-term results we developed a telephone questionnaire for all the patients centralized on the grade of satisfaction, the efficiency of the treatment, the compensatory sweating and the observed changes in life quality. The medium follow-up time was 26.5 months (rango 6 months to 4 years). RESULTS: In total 6 patients were reviewed (4 female, 2 male), medium age 12, 8 years (rango 8 to 18 years). Thoracoscopic sympathectomy was done at the level of T2 or T3 associating T4 in 1 case. We just observed 1 postoperative complication which consisted in a disestesia of the upper extremity and which disappeared spontaneously without sequels. Patients referred total relief of palmar sweating. Only 1 case reported residual sweating unilaterally in the tenar region, but in all of them sweating of feet still persisted (3 of low grade and 3 of moderate grade). In 50% of the cases we observed compensatory sweating localized at the back of moderate grade in 2 patients and at the upper legs of more severe grade in 1 of them. Only this last patient reported that the compensatory sweating affected his everyday life. We also observed that the patients where the sympathectomy had affected more than 1 ganglia (T2+T3; T3+T4; T2+T3+T4) referred a higher grade of compensatory sweating. All the cases reported an important improvement in life quality, in the social as in the formative manner. They were all very satisfied with the results of the surgery and none of them (neither the children nor the parents) regretted the intervention. The cosmetic result of the surgical scars was also satisfactory. CONCLUSIONS: The thoracoscopic sympathectomy is an efficient procedure for the treatment of palmar hyperhidrosis. Despite the compensatory sweating patients usually are very satisfied with the results. Since palmar hyperhidrosis is not a pathology which improves spontaneously and the surgical treatment has minimal complications we do not think that the surgery should be postponed in pediatric patients.

INTRODUCTION: Percutaneus gastrostomy placement is a procedure widely performed in children with failure to thrive or intolerance to oral feeding. At the moment of making the indication, the need of an antir-reflux surgery in the same procedure comes to question. The aim of this study was to analyse which preoperative factors are associated with a higher risk of a posterior fundoplication. MATERIAL AND METHODS: We realized a retrospective review of 67 patients divided in 2 groups (cases and controls) in which a percutaneus gastrostomy (PEG) had been made by our service in the period of 1997 to 2008. We compared these two groups: Group A (n=11) - patients with severe gastroesophageal reflux who required a Nissen procedure afterwards; Group B (n=56) - patients who kept without reflux after PEG. We analyzed the different preoperative factors that could have been in association to severe reflux after gastrostomy. RESULTS: Mean age at the moment of undergoing PEG was 15 months. Mean time of follow up was 3,5 years. Only neurological impairment and documented reflux pregastrostomy were associated with the need of an antirreflux surgery after PEG. CONCLUSIONS: Neurological impairment and documented pregastrosotmy GER could be an indication of concurrent antirreflux surgery at the time of gastrostomy.

OBJECTIVE: This study was aimed at estimating type-specific HPV prevalence and its cofactors among Honduran women with normal cytology in order to provide valuable information to health policymakers about the epidemiology of this important sexually transmitted infection. METHODS: A total of 591 women with normal cytology from Tegucigalpa, Honduras were interviewed and tested for HPV using the SPF10 LiPA25. A structured epidemiological questionnaire was administered to each woman. RESULTS: The overall HPV prevalence was 51%. Twenty-three types of HPV were detected; HPV 16, 51, 31, 18, and 11 were the most common. The highest prevalence of cancer associated HPV types (15.0%) was found in the women less than 35 years. Besides the association with age, the main independent predictors of HPV infection were the lifetime number of sexual partners and having a low socioeconomic status and less than 5 previous Pap smears. CONCLUSIONS: In the population studied, there was a broad diversity of HPV infections, with high-risk types being the most common types detected. The establishment of a well-characterized population with regard to the community prevalence of type-specific HPV infection will provide a valuable baseline for monitoring population effectiveness of an HPV vaccine.

INTRODUCTION AND AIMS: Although the incidence of emphyema is increasing it continues to be a widely debated pathology in relation to its management. We analyzed the last 36 cases treated by our service in the last 2 years. MATERIAL AND METHODS: We retrospectively studied the last 36 cases of parapneum6nic pleural effusions that needed some type of treatment at our service from March, 2005 to May, 2007. For this we analyzed: average age, time of evolution before admission to hospital, time of evolution from admission to surgery, location of the pneumonia, echographic characteristics, value of the pH and glucose, the relation between the presence of echoes in the ultrasound scan with the value of the pH and of the glucose, the relation between value of the pH and glucose with the evolution, type of treatment and evolution. We used for the statistical study ANOVA's test and paired t-test and the student's T test. RESULT: The average age was 5.4 years (range 9 months-15 years). The average time of evolution prior to admission to the hospital was 5.6 days (range 0.5-20 days) and the average time from admission to surgery was 5.1 days (range 0-65 days). The pneumonia was multilobar in 38.2% of the cases, in low lobes in 52.9% (29.4% in the left lower lobe and 23.5% in the right lower lobe). Ultrasound scan was performed in 97.2% of the patients, being severely septated in 31.4% of the cases, clear liquid 25.7%, moderately septated 22.8% and minimally septated 17.1%. The pH was analyzed in 69.4% of the effusions, the average value being 7.16 (range 6.75-7.45). The glucose was analyzed in 61.1% of the effusions, the average value being 61.1 (range 1-123). Septated effusions in the ultrasound scans were related to the lowest values of pH and glucose (p = 0.0001 in both cases). When we analyzed the relationship between clinical evolution and the pH we observed that a lower value of pH was related to a worse evolution, finding that pH values below 7 are related to a bad evolution (p = 0.001). The same results were found when we analyzed the relationship between the evolution and glucose (p < 0.005). CONCLUSIONS: The pH and the glucose in complicated parapneumonic pleural effusion have a pronostic value for evolution, regardless of what treatment was used. We found that pH values below 7 are related to a bad evolution.

INTRODUCTION: The management of complex subglottic stenosis is difficult, existing different surgical techniques for its treatment, depending on type and grade of stenosis, comorbidities and the state of the patient. We studied the management of the complicated patients in our centre analyzing the applied treatment, the type and grade of stenosis, and the results in order to develop a treatment protocol of complex subglottic stenosis. MATERIAL AND METHODS: Of a total of 120 patients diagnosed of subglottic stenosis in follow-up in our centre we retrospectively reviewed 15 patients (5 boys, 10 girls; medium age 1.63 years, range 0.05 to 13 years) who had suffered mayor complications and who had required reinterventions (1 to 6). We analyzed the employed techniques in relation to the observed complications and the previous treatment, the results and the decanulation index. All diagnoses were established by fiberbronchoscopy and the initial treatment was realized following the actuation guidelines of Cotton. RESULTS: The global decanulation index in this group of patients was 80%. The patients in who initially a anterior cricoid split had been done and who developed a subglottic stenosis grade III were 8. Rescue treatment consisted in anterior laringotracheoplasty in 7 cases managing decanulation in 6 patients (75%). The medium number of reinterventions was 2.5. Patients treated initially with Laser (n=4) developed a subglottic stenosis grade III in two cases and grade IV in the rest. Subglottic stenosis grade IV were corrected by cricotracheal resection and subglottic stenosis grade IV by anterior laringotracheoplasties with a medium reoperation Lumber of 1.25. All patients achieved decanulation (100%). Failed anterior laringotracheoplasties with cartilaginous grafts (n=2) developed grade III subglottic stenosis, one was treated with a double laringotracheoplasty and the other with a cricotracheal resection reaching decanu-lation in both patients (100%). Reintervention number was one to four. Only one cricotracheal resection as initial treatment failed. This patient required 3 reinterventions not being decanulation possible (0%). CONCLUSIONS: Patients with complex subglottic stenosis often require more than one reintervention until reaching decanulation. Decanulation index in these patients is satisfactory. The development of a management protocol for these cases is very difficult and treatment should be individualized.

UNLABELLED: Tracheal stenosis (TS) is an unusual and sometimes lethal condition. It's treatment is basically surgical and different techniques have been proposed. AIM: Analyze the outcome of patients with TS diagnosed and treated in our institution realted to the applied surgical technique during the study period. MATERIAL AND METHODS: The clinical records of patients with TS (period 1991 to 2006) were reviewed analyzing the following variables: age, gender, associated malformations, intubation time, medium hospital stay and outcome. Patients were divided in 4 groups: conservative and endoscopic management (2 conservative, 1 dilatation, 1 laser), tracheal resection with termino-terminal anastomosis (RTA) (9 patients), tracheoplasties (slide or modified plasties) (20 patients) and anterior tracheoplasty with costal cartilage graft (TAIC) (6 patients). Results are expressed as media +/- standard error, comparative analysis was done using Chi square with continuity correction. Differences were considered statistically significant with a p < 0.05. RESULTS: 39 patients were reviewed (23 male, 16 female), medium age was 2.23 years. Associated malformations were: 12 vascular rings, 7 cardiac malformations, 4 Down syndromes, 1 pulmonary agenesia, 2 hemivertebtebrae, 1 renal agenesia and 1 cervicothoracic angiomatosis. Nineteen patients had short segment stenosis, 15 long segment stenosis (more than 1/3 of tracheal length) and 5 patients presented associated bronchial stenosis (most frequently right main bronchus). All TAIC failed: 4 deaths, 1 reestenosis and 1 persistent stenosis. In the tracheoplasty-group there were 2 exitus (1 due to a neurological lesion after a prolonged preoperative cardiorrespiratory arrest, one due to a surgical treatment delay with previous inadequate management). Patients treated with tracheoplasties and RTA had a favourable evolution and are asymptomatic in more than 80% of the cases after a mean follow-up of 59.9 +/- 7.4 months. In the conservative management group 2 patients died and 2 had a uneventful outcome. Global mortality was 20.5% (8 deaths). Differences observed in the mortality percentage between the study groups were statistically significant. (p = 0.0034) (50% in conservative management, 0% in RTA, 10% in tracheoplasties, 66.67% in TAIC). No statistically significant differences were found in the medium intubation time, medium hospital stay and medium follow-up time. CONCLUSIONS: The fundamental treatment of the tracheal stenosis is the surgical approach. Patients should be studied with great detail taking into account associated malformations (mostly heart defects and vascular rings) and should be treated by a multidisciplinary group. Short segmental TS should be corrected with RTA, long TS with tracheoplasties (slide), remaining the TAIC technique obsolete.

UNLABELLED: Laser application for the treatment of pediatric airway pathologies represents a very attractive option because of the limited inflammatory reaction after photocoagulation. One novel laser used for such pathologies is the diode laser. AIM: The purpose of this report is to present our preliminary experience in the use of diode laser in the treatment of pediatric airway lesions. METHODS: A retrospective review of 22 patients (11 males and 11 females) who underwent laser procedures from 1999 to 2006 was performed. Nineteen patients were treated at our center while 3 were referred after a laser application from other institution. In all procedures flexible bronchoscopy was used. The mean age was 1.25 years (range 1 month-4.8 years). Lasers were applied for various lesions: laryngomalacia and arytenoid lesions (n = 5), angiomas (n = 3), lymphangiomas (n = 3), sacular cyst and other mucous lesions (n = 3), granulomas, scarring lesions (n = 4) and paralysis of vocal cord in adduction (n = 1). RESULTS: None of the patient developed complications related to the endoscopic laser application. The mean number of laser therapy attempts were 1.4 per patient (range 1-3). The patients remained intubated for a mean of 2.8 days (range 4 hours-13 days) after the procedure. The duration of PICU stay after laser therapy was a mean of 4.6 days (range 1-8 days). The best outcomes were seen in sacular cysts (excelent in 3 patients). Also, all 3 patients with granulomas showed a good response to treatment. Multiple laser sessions (1-3; mean 1.4) were required to sucessfully manage the artynenoid lesions. However, the children with vascular lesions demonstrated differents outcomes. Of the 3 patients with subglottic angioma, 2 underwent a subsequent surgical procedure due to the development of subglottic stenosis; and one requiered further systemic steroid therapy. Of the children with lymphangioma, one needed 3 laser sessions and two required surgi- cal resections. Despite laser treatment, 3 of the 4 patients with scarring lesions required surgery. CONCLUSIONS: The endoscopic application of diode laser for the management of pediatric airways lesions provides good outcomes in selected patients. Sacular lesions, granulomas and arytenoid lesions are, in our experience, excellents indications. In other anomalies laser is a good adjuvant. The application of laser should be tailored according to the pathology.

INTRODUCTION: Surgical approach of the cervicothoracic junction has been traditionally done by cervicotomy and/or thoracotomy. Nevertheless, this access does not allow a suitable control of vasculonervous structures. Due to this we present our experience with a variation of the "Trap-door" thoracotomy which gives the best access to this area applied to pediatric patients METHODS: We present 4 patients of 2.8 +/- 1.9 years of age treated in our hospital by a cervicothoracotomy transmanubrial approach without clavicular luxation. One patient presented a stage IV cervicothoracic neuroblastoma, 1 patient had a cervicothoracic lymphangioma, one a severe cervicothoracic scoliosis and one a total cricoid atresia associated to an oesophageal atresia type IIIc (Vogt). This surgical approach allowed a perfect control of brachiocefalic and nervous structures as well as a correct visualization of all the cervicothoracic intervertebral foramina. Postoperative pain was controlled by epidural catheters, oral analgesic treatment was introduced in the fifth postoperative day. RESULTS: Complete resection and surgical treatment was possible in all patients, not being necessary the section of any vascular or nervous structure. There were no intraoperatory or postoperative complications. One patient presented a temporary Homer's syndrome. No tumoral recurrence has been noted after a mean follow-up of 2.3 +/- 3.1 years. CONCLUSION. The modified "Trap-door" approach allows a good control of the brachiocephalic structures and a complete visualization of the upper thorax and posterior mediastinum. Due to its low morbidity this access may be very useful since it allows an important vascular control and an excellent surgical field. Our modification of the "Trap-door" approach avoids clavicular luxation and has the advantage of no sequelaes in the functionality of the escapulo-humeral articulation.

OBJECTIVES: To analyze the causes of stridor in infancy and its treatment. MATERIAL AND METHODS: Ninety patients under 1 year of age with stridor (93.06 +/- 82.4 days) were included. All patients were diagnosed by fiberoptic bronchoscopy. RESULTS: Thirty-eight patients were referred from the pediatric and neonatal intensive care units, 23 from an outpatient clinic and 29 from other hospitals. Diagnoses were subglottic stenosis in 21 patients, tracheobronchomalacia in 20, laryngomalacia in 20, tracheal stenosis in 17, cervical hemolymphangiomas in five, vocal cord palsies in four, and glottic edema in three. Forty-six patients (51.1 %) required surgery: 14 for functional disorders and 32 for anatomical anomalies. Six patients required further surgery: five with subglottic stenosis and one with tracheal stenosis. Outcome was very good or good in 75 patients (83.4 %) and was fair or poor in eight (8.8 %). Seven patients (7.8 %) died. Causes of death were an associated congenital heart disease in four patients, sepsis in one, bronchopneumonia in one, and suture dehiscence in an anterior cartilage graft tracheoplasty in one. CONCLUSION. According to our results, fiberoptic bronchoscopy should be performed in infants with stridor, as an underlying anomaly requiring surgical treatment is frequently found. The severity of stridor does not always correlate with the severity of the lesion. Potentially lethal causes can be found, requiring early treatment.

INTRODUCTION: Aspiration of foreign bodies in children is a frequent and potentially serious condition. Traditionally it has been solved by rigid bronchoscopy. Nowadays an increasing number of authors support the use of flexible bronchoscopy for its resolution. AIM: Analyze our experience in airway foreign body removal in children using flexible bronchoscopy. MATERIAL AND METHODS: We retrospectively analyzed 65 patients diagnosed of foreign body aspiration with a mean age of 3.65 + 3.1; 60% males and 40% females. We compared two historical cohorts of homogeneous distribution. The first one (group A), from 1994 to 1998, included 41 children treated by rigid bronchoscopy, and the second one (Group B) (1999-2006) 24 patients treated with the flexible bronchoscope. We studied: rate of success of initial extraction (RSIE), foreign body localization, type of foreign body, hospital stay, complications and mortality. Statistical analysis was done using t-student for cuantitative variables, and chi square for cualitative. Only a p < 0.05 was considered statistically significant. Data are presented as mean +/- standard error of the mean. RESULTS: Group A had a medium hospital stay of 1.89 + 2.6 days. RSIE was 85.36%. Six patients needed a second therapeutic procedure (5 rigid bronchoscopies, 1 flexible brochoscopy). Complication rate was 4.87%: 2 cases of bronchitis. Group B presented a medium hospital stay of 1.34 +/- 0.27 days with a RSIE of 70.83%, needing a second intervention 7 children (4 fiberbonchoscopies, 3 rigid bronchoscopies). Postextraction complications in this group consisted of 1 bronchitis episode and a pneumothorax in 2 patients (8.33%). No deaths occurred in any group. No statistically significant differences were found in hospital stay, RSIE, type of second therapeutic procedure and complication rate. CONCLUSIONS: Our experience shows that flexible bronchoscopy removal of airway foreign bodies is safe and efficient; therefore, we think that it should be taken into account as first choice method of treatment at any age.

AIM: To determine if the needs of cardiopulmonary support of neonates with congenital diaphragmatic hernia (CDH) they can be indicators for the election of the most suitable moment to the surgery. METHODS: We treated 16 consecutive neonates with congenital diaphragmatic hernia (CDH) from 2004 to 2005. Mean birth weight was 2900.63 +/- 531.51 g. Patients was divided in 2 groups. Group A: newborns without adrenaline nor noradrenaline like vasoactive drugs and conventional respiratory assistant; the surgery was performed during the first 48 hours of life. Group B: newborns with adrenaline or noradrenaline like vasoactive drugs, high-frequency oscillatory ventilation or extracorporeal membrane oxygenation; surgery was delayed (10.66 +/- 8.26 days). RESULTS: Four neonates died during the first 24 hours of life without surgical treatment not fulfilling criteria of support ECMO. Five patients were operated during the first 48 hours, fulfilling all of them the clinical criteria of the group A. Mortality does not exist in this group. Seven patients were operated late fulfilling the criteria of the group B. They all needed VAFO. Two patients of this group needed support ECMO. The survival rate in this group was 83.3%. DISCUSSION: In our opinion, the patients with CDH that need initially high cardiopulmonary support, VAFO and/or ECMO would be necessary a time of wait to realize the surgery. In those patients who don't need this level of treatment the delay would not justify itself in the surgical intervention.

AIMS: Analysis of main factors of spinal cord and vertebral column injuries in our environment. METHODS: We reviewed the data collected from the patients (n = 2640) admitted to our hospital because of trauma and included in our Registry from January 1995 to April 2002. Among this group, 86 patients (3.3%) had spinal cord and vertebral column injuries and were included in the study. RESULTS: Group gender distribution was 45 males and 41 females. In our group, 71 patients suffered vertebral fractures, 3 of them with spinal cord injuries (4.2%), 13 patients with vertebral subluxation, 11 of them between C1-C2, and 2 patients with spinal cord injury without radiographic abnormality. Only 71 patients, 4.9% of the total of the patients who were admitted with any type of fracture (n=1457), suffered vertebral fractures. These patients suffered 130 vertebral fractures, 35 of them (49.3%) suffered multiple fractures. Thoracic vertebrae were the most frequently affected (n=82, 63%). The most frequent localization was T4 toT8 (n=50, 38.5% and T11 to L2 (n=41, 31.5%). Age ranged between 12 and 15 years (n=35, 49.3%), with only 5 patients under 6 years. 90.9% of the patients with lumbar fractures were older than 8 years and 76.9% of the patients with cervical fractures were over 8 years. Motor vehicle accident was the most common cause in our series (n=20, 23.3%). 81% of these patients did not use safety belt. Ten children with cervical injuries were seen by medical staff at the prehospital stage, and only 4 of them arrived to Hospital with cervical collar. There were thirty five patients with thoracic or lumbar injuries but only 27 of them were transferred to our Institution by ambulance. Surgery was required in 2 patients, both of them with unstable fractures. Mean hospital stay was 17,1 days (range 2-37 days). CONCLUSIONS: Group gender distribution is similar between males and females and the incidence in our series is higher than other series of the literature. Thoracic injuries are the most frequent. It is necessary to improve prehospital management of these patients and to increase the use of safety belt. Spine injury incidence increased with age.

UNLABELLED: Peritoneal drainage (PD) has been proposed as a temporizing procedure for perforated necrotizing enterocolitis (NEC) in very low birth weight neonates. This operation was designed for patients considered too unstable to undergo laparotomy (LAP). Since the introduction of PD some investigators have suggested that it may serve as a definitive therapy. The aim of our study is to determine the efficacy of PD for the stabilization of patients with complicated NEC and its utility as a definitive surgical treatment. METHODS: We review the clinical records from all the patients treated in our unit because of NEC that required surgical therapy. We analyze the mean blood pressure, cardiac and respiratory rate, inspired oxygen concentration, mean airway pressure, diuresis, and arterial blood gases measured 6 and 12 hours after the initial surgical treatment. We divide patients in two different groups according to the initial surgical procedure, peritoneal drainage (PD) or laparotomy group (LAP). Data is shown as media +/- standard deviation, statistical analyses were performed using analysis of variance (ANOVA) for repeated measures and Mann-Withney test. RESULTS: From January 1997 to January 2001 we treated 13 patients with necrotizing enterocolitis that required surgical treatment. Among this group 6 patients were managed initially with PD and 7 with LAP. The gestational age media was 29.07 +/- 3.81 weeks and the birth weight mean 1199.76 +/- 521 gr., without any significant differences between the two groups DP and LAP. All patients improved haemodynamically and respiratory 6 and 12 hours after the surgical treatment. Nevertheless, the mean blood pressure improved even more in the DP group (p<0.005). The DP group showed an improvement in all parameters 6 hours after the drainage was placed, but this effect wasn't maintained for the next 12 hours onwards. From the 12 hours after PD all patients suffered a steady worsening that required further surgical procedures. The overall mortality was 3 patients (23%), without differences between the two groups. The surgical techniques performed (bowel resection, diversion) were similar for both groups. DISCUSSION: DP allows the stabilization for very critically ill patients with complicated NEC. However, this stabilization is temporary. This improvement lasts for a few hours providing a better status for the definitive surgical treatment for the perforated NEC. In our experience DP could not be considered as a definitive surgical treatment.

Two cases of late hypophosphatemic osteomalacia are described: a male aged 30 who had the disease since he was 22 and a woman of 23 who had the disease since she was 14. Both presented with myopathy and bone pain, and showed hypophosphatemia, hyperglycinuria, reduced tubular phosphate reabsorption (TPR), increased hydroxyprolinuria and normal iPTH and iCT values. Radiologically the male had no Looser's zones and the woman did. Bone biopsy confirmed hypophosphatemic osteomalacia. Both cases were treated with vitamin D and oral phosphate and no improvement was observed. When treatment with 25(OH)D3 was initiated, no improvement was seen and afterwards this was combined with treatment using 1.25(OH)2D3 and from this time on a clinical improvement of the myopathy became evident in both patients. In the woman, healing of the bone lesions occurred at the same time as that of the myopathy, whereas in the male the bone lesions became worse. Healing of the myopathy was only obtained when treatment with 1.25(OH)2D3 was begun. Both patients had reduced values of 2.3 erythrocytic DPG and low level of serum phosphorus when the myopathy was cured, which suggests a lack of effect of 2.3 DPG or serum phosphorus as a cause of the myopathy. Although this had been attributed to a deficiency in the function of 25(OH)D3, the response to 1.25(OH)2D3 and due to the effects of this metabolite on calcium transport in muscle, suggests that the myopathy which occurs in late hypophosphatemic osteomalacia is a result of deficiency or resistance to the muscular effect of this metabolite. We cannot explain the lack of bone healing in the man and further therapeutic studies are required.

The clinical features of a new patient with dysplasia epiphysialis multiplex are reported. Similar symptoms are present in four members of the family. This disease seems to be inherited as a simple dominant Mendelian trait. The disease mainly affects the epiphyses of the long bone and nearly always begins with pain in the hip-joint. Our patient presented radiological features of osteoporosis with calciotropic hormones within normal range and with a low trabecular bone volume. This histomorphometric bone study shows a low bone turnover osteoporosis, which suggests an altered trabecular development with a greater clinical expression in the epiphyses.

Intraluminal masses within the upper urinary tracts are rare, are almost always benign, and most commonly take the form of fibroepithelial polyps within the ureters. Only exceptionally are these lesions found within the renal pelvis and for that reason may cause diagnostic difficulty. We present a new case of fibroepithelial polyp of the renal pelvis treated successfully in our hospital.

PURPOSE: The aim of this study was to evaluate the results obtained by 2 different techniques of tracheoplasty in the treatment of long-segment, funnel-shaped congenital tracheal stenosis (CTS) in 2 tertiary paediatric hospitals. METHODS: The clinical records of patients with long segment congenital tracheal stenosis during the period January 1990 to June 1999 were reviewed retrospectively. Age, gender, symptoms, imaging (x-ray, computed tomography, magnetic resonance imaging, or bronchography), endoscopic findings, associated anomalies, treatment, intubation time, postoperative treatment, intensive care unit stay, complications, hospital stay, evolution, and follow-up time were analyzed. Short congenital tracheal stenosis treated by resection and end-to-end anastomosis are not included. Results are given as mean +/- SEM. RESULTS: Ten (7 boys, 4 girls) of 14 patients with CTS had a funnel-shaped CTS. Mean age at treatment was 9.7 +/- 4.8 months (range, 3 days to 4.7 years). All of the patients presented with CTS affecting the distal third of the trachea and 4 of them extension to 1 main stem bronchus. They were treated by 2 different types of tracheoplasty: anterior costal cartilage graft (ACGT, 6 patients) and slide tracheoplasty (ST, 4 patients). All the patients treated by ACGT failed: 4 died and 2 required further surgery for restenosis. Causes of death were acute respiratory failure during surgery (2 cases) and anastomotic dehiscence (2 cases). The patients treated with ST are asymptomatic and doing well. Mean postoperative intubation time of the ACGT group was 35 +/- 25 days (10 to 60 days), whereas in the ST group it was 14 +/- 12 days (0 to 51 days). Mean hospital stays were 292 +/- 271 days (21 to 563 days) and 24 +/- 13 days (7 to 63 days), respectively. Mean follow-up time is 28 +/- 14 months (3 to 94 months). CONCLUSIONS: Surgery of long-segment congenital tracheal stenosis has a high failure and complication rate with vital implications in prognosis. Treatment should be done in a multidisciplinary basis by a highly trained and motivated team. Slide tracheoplasty seems to be the better option, although further multicentre studies should be conducted.
