Abstract
PURPOSE The management of overriding distal forearm fractures is still controversial. This study aimed to evaluate the efficacy of immediate closed reduction and cast immobilization (CRCI) at the emergency department (ED) using equimolar nitrous oxide (eN2O2) as conscious sedation, and without the use fluoroscopic assistance. METHODS Sixty patients with overriding distal forearm fracture were included in the study. All procedures were performed in the ED without fluoroscopic assistance. Antero-posterior and lateral wrist radiographs were taken after CRCI. Follow-up radiographs were taken 7 and 15 days post-reduction, and at cast removal to evaluate callus formation. Depending on the radiological outcome, two groups of patients could be identified: Group 1 (satisfactory reduction and maintenance of alignment) and Group 2 (poor reduction or secondary displacement requiring further manipulation and surgical fixation). Group 2 was additionally divided into Group 2A (poor reduction) and Group 2B (secondary displacement). Pain was assessed using Numeric Pain Intensity (NPI) score, while functional outcome was measured according to Quick DASH questionnaire. RESULTS Mean age at the time of injury was 9.2 ± 2.4 years (range, 5-14). Twenty-three (38%) patients were aged between 4 and 9 years old, 20 (33%) patients between 9 and 11, 11 (18%) patients between 11 and 13, and 6 (10%) patients between 13 and 14. The mean follow-up time was 45.6 ± 12 months (range, 24-63). Satisfactory reduction with maintenance of alignment was achieved in 30 (50%) patients (Group 1). Re-reduction was performed in the remaining 30 (50%) patients (Group 2) due to poor reduction (Group 2A) or secondary displacement (Group 2B). No complications related to the administration of eN2O were recorded. No statistically significant difference could be identified between the three groups for any clinical variable (Quick DASH and NPI). CONCLUSION Overriding distal forearm fractures may be safely treated with CRCI at ED using eN2O2 as conscious sedation. However, fluoroscopic assistance during CRCI might significantly improve the quality of reduction thus avoiding further treatment as the lack of relaxed muscle can restrain reduction.

Abstract
Introduction Idiopathic clubfoot (IC), also referred to as congenital talipes equinovarus, is one of the most common lower limb deformities observed in newborns, leading to significant functional impairment when left untreated. Early minimally invasive treatment has been praised as one of the most successful practice of modern pediatric orthopedics. This review aims to report current knowledge and controversies about clubfoot treatment. Material and methods We describe the main trends in clubfoot managing, identifying peculiarities, difficulties and prognostic factors related to the treatment. Results Many treatment techniques either conservative, surgical or hybrid have been used over the past decades. Based on good and excellent results during long-term follow-up, Ponseti method has been globally accepted by paediatric orthopaedic surgeons as standard method of treatment. However, some other conservative methods are still widely applied in the clinical setting, such as the French Physical Therapy method. Adherence to the bracing protocol is critical for the long-term success of the treatment, being a better predictor for relapse than severity of the deformity at birth. Conclusions Taking care of the manipulation and casting details by trained professionals, together with enhancing the child and patents’ adherence to the brace, are essential for the success of conservative treatment. Surgery should be performed only when strictly needed, preferably on a “a la carte” approach.

Abstract
Introduction Management of pediatric long bones fractures is a complex and rapidly evolving field. Traditionally, casting and conservative techniques played a key-role in the management of fractures in skeletally immature patients. However, the surgical approach has evolved steadily over the past four decades or so and increasing evidence has been published supporting the advantages of fixation techniques over conservative methods. The purpose of this narrative review is to outline how innovations in orthopedic surgery have changed the rationale of treating long bones fractures in children and adolescents with focus on surgical techniques, particularly elastic stable intramedullary nailing (ESIN). Material and methods We aimed to describe the main trends in pediatric long bones fractures management and to identify its specificities and difficulties as well as the best standard of care. Results The introduction of ESIN has profoundly influenced the management of pediatric upper and lower extremity fractures. Overall, in comparison to conservative techniques, advantages of ESIN include minimally invasiveness, short hospital stay, primary bone union, early mobilization and progressive weight bearing, and good outcome with low complication rate. Moreover, the flexible nail can be used as a closed reduction tool itself. Conclusions Irrespective of the technique performed, the key-concepts remain 1) the proper understanding of the injury to treat; 2) the identification the main characteristics of the patient; 3) the pros and cons of each technique; and 4) the potential complications.

Abstract
PURPOSE To assess skull bone thickness from birth to skeletal maturity at different sites to provide a reference for the correct selection of pin type and pin placement according to age. METHODS 270 children and adolescents (age: 0-17 years) with a normal CT scan obtained at Emergency Department for other medical reasons were included. Skull thickness was measured on the axial plane CT scans at eight different sites of the vault: midline anterior (A) and posterior (P), right and left lateral (L), antero-lateral (AL), postero-lateral (PL). RESULTS From birth to skeletal maturity, L thickness was increased significantly less (+ 58%) compared with AL (+ 205%), P (+ 233%), PL (+ 247%), and A (+ 269%) thickness (P < 0.01). At the end of growth, the thickest and thinnest points of the vault (absolute value) were found at the P and L measurement sites, respectively (P < 0.01). Children aged < 4 years exhibited the highest variability in AL and PL skull bone thickness, with thickness < 3 mm observed in 85% (64/75 patients) and 92% (69/75 patients) of cases, respectively. CONCLUSION We recommend that the tip of the pin should not exceed 2-3 mm in children aged < 4, and 4 mm in children aged 4-6 years, to decrease the risk of inner table perforation. After the age of 7 years and 13 years, standard-sized pin tips (5 and 6 mm, respectively) may be safely used. Children aged < 4 years show significant variability in skull thickness, and therefore a CT scan may be required for this particular age group.

Abstract
PURPOSE The main objective of this study was to retrospectively evaluate the clinical and radiological outcomes of acute (AMF) and chronic Monteggia fractures (CMF) in children treated by closed or open reduction and external fixation (EF). METHODS This is a retrospective review of 26 patients with Monteggia fracture. Patients with AMF (time between trauma and surgery less than two weeks) were treated by closed reduction and EF of the ulna (Group A; 15 patients) while those with CMF (time between trauma and surgery more than three weeks) were managed by closed or open reduction and EF of the ulna (Group B; 11 patients). Clinical outcome was evaluated with radiography and the short version of the Disabilities of the Arm, Shoulder and Hand outcome questionnaire (Quick DASH). Complications were recorded in both groups. RESULTS No secondary displacement, wire migration, consolidation delays, nonunion, malunion or re-fracture was noted. However, one patient in Group A (6.7%) developed heterotopic ossification of the ulna; the final functional outcome was good (Quick DASH score: 18.2). One case of postoperative redislocation of the radial head was detected in Group B (9.1%). Two patients (7.6%) developed transient pin tract infection. Despite the fact that 16 out of 26 patients (six in Group A and ten in Group B) complained of the clinical appearance and/or had intermittent residual pain on the injured side, the results were essentially the same between the two groups of patients (p > 0.05). CONCLUSION EF is an alternative for the management of acute and chronic paediatric Monteggia fractures. It provides satisfactory radiological and clinical outcomes with relatively low rates of complications. LEVEL OF EVIDENCE IV.

Abstract
PURPOSE The purpose of this study was to explore whether increasing the hip abduction angle would increase the incidence of avascular necrosis (AVN) in patients with late- detected developmental dysplasia of the hip (DDH) treated by closed reduction (CR) and spica cast immobilization. METHODS A total of 55 patients (59 hips) with late-detected DDH underwent MRI after CR. Hip abduction angle and hip joint distance were measured on postoperative MRI transverse sections. The acetabular index and centre-edge angle were measured on plain radiographs at the last follow-up. The presence of AVN according to Kalamchi and McEwen's classification was assessed. We retrospectively analyzed the associations among abduction angles, hip joint distances, radiographic parameters, AVN and final outcomes, exploring the relationship between hip joint abduction angle and AVN rate. RESULTS The mean age at the time of CR was 14.4 months SD 5.5 (6 to 28), and the mean follow-up was 26.2 months SD 8.1 (12.4 to 41.7). The mean hip abduction angle was 70.2° SD 7.2° (53° to 85°) on the dislocated side and 63.7° SD 8.8° (40° to 82°) on the normal side; the mean hip joint distance was 5.1 mm SD 1.9 (1.3 to 9.1) on the dislocated side and 2.2 mm SD 0.6 on the normal side (1.3 to 3.3). Eight of 59 hips (13.6%) developed AVN. Neither the amount of abduction nor hip joint distance increased the AVN rate (p = 0.97 and p = 0.65, respectively) or the dislocation rate (p = 0.38 and p = 0.14, respectively). CONCLUSION Abduction angle up to 70.2° following CR did not increase the AVN rate in children aged six to 28 months with late-detected DDH treated by CR. LEVEL OF EVIDENCE III.

Abstract
The main objective of this paper is to review the current literature on treatment of tibial and femur fractures in children and adolescents guided by body weight in patients weighing 50 kg (110 lb) or more. A secondary aim of this mini-review was to determine, as per literature review, whether weight > 50 kg (110 lb) is an identifiable factor associated with increased complication rate. A search of the PubMed/MEDLINE, EMBASE and Cochrane Database of Systematic Reviews databases from 1954 to September 2017 was performed to identify papers related to pediatric tibia and femur fractures in children weighing more than 50 kg (110 lb). Abstracts were screened, and relevant full-text articles were retrieved for further review. Reference sections of identified papers were also screened to identify further literature. All levels of evidence were included. Overall, seven full-text articles dealing with pediatric tibia or femur fractures in patients weighing more than 50 kg (110 lb), and one article reporting on both femur and tibia fractures in this patients' population, have been identified (n = 8 full-text article included). The articles reviewed a total of 679 children. In particular, 48/438 femur shaft fractures (mean weight: 51.7 kg or 113.9 lb) and 91/241 tibia fractures (mean weight: 53.3 kg or 117.5 lb) met the inclusion criteria. The overall rate of complications was 27.9%. In particular, the rate of complication was 51.7 and 29.6% in children with femur and tibia fracture weighing more than 50 kg (110 lb), respectively (p < 0.05). Elastic stable intramedullary nailing (ESIN) has become the treatment of choice for displaced tibia and femur shaft fractures in children between six and 12-15 years of age. Unstable fracture pattern, higher age and higher weight have been reported as potential risk factors associated with poor outcomes in children and adolescents treated with ESIN for displaced long bone fractures of the lower extremity, in particular femur shaft fractures. Despite these findings, data reporting exclusively on ESIN-treated long bone fractures in children weighing 50 kg (110 lb) or more remain scant.

Abstract
PURPOSE To quantitatively evaluate the upper extremity and elbow function with the Mayo Elbow Performance Score (MEPS) in children with transphyseal fracture of the distal humerus (TFDH) treated surgically. METHODS During the period between 2005 and 2015, a total of 16 patients (ten male, six female) met the inclusion criteria. Mean age at the time of injury was 18 months (11 to 37) and mean follow-up was 42.3 months (6 to 98). Based on a modified version of Delee's classification (Group A to C), the clinical and radiographic outcome of TFDH in toddlers treated surgically were retrospectively evaluated. RESULTS Mean humeral-ulnar (HU) angle of the injured and non-injured side was 1.2° (-18° to 14°) and 8.8° (2° to 19°), respectively (p = 0.001). Closed and open reduction showed similar HU angle values (p = 0.682). Mean MEPS score of the injured and non-injured side was 85.5 points (70 to 95) and 95 points (90 to 100), respectively (p = 0.002). No significant association was identified between MEPS score and gender, side, age at trauma, direction of displacement, time from trauma to surgery, presence of ossified capitellum, type of surgery and type of fracture. CONCLUSION Functional outcome was generally good regardless of surgical procedure performed, closed or open and type of fracture according to modified Delee's classification. However, a residual cubitus varus was commonly observed among toddlers with transphyseal fractures of the distal humerus. LEVEL OF EVIDENCE Level IV - Therapeutic study.

Abstract
A fracture is defined as pathological when it arises in a bone tissue that has been modified and reshaped by a local or systemic pathological process. In children, pathological fractures can be secondary to several conditions, ranging from metabolic diseases to tumors, infections or neuromuscular pathologies. History, clinical examination and radiologic assessment are essential to making a diagnosis, to identifying the underlying cause and to planning the right treatment of a pathological fracture. Treatment must be tailored to both the fracture and the underlying cause. The objective of this work is to present the diagnostic approach and the course to follow when a child presents with a pathological fracture. The most common causes of pathological fractures, as well as their characteristics, will be described. Pathological fractures occurring in osteogenesis imperfecta and in abused children as well as stress fractures will not be discussed.

Abstract
BACKGROUND Dysplasia epiphysealis hemimelica (DEH) is a rare developmental bone disorder with hemimelic involvement of one or more epiphysis. We report on nine new cases and discuss the clinical manifestations, the value of MRI, and the results of complete and early surgical resection of these lesions. MATERIALS AND METHODS In this retrospective study, nine patients with a diagnosis of DEH were evaluated. Age at presentation ranged from 1 year to 12 years. The main complaint at diagnosis was a swelling bony mass. Angular deformities were recorded in two patients. All patients were surgically treated and followed up clinically and by imaging. Eight patients underwent excision only. RESULTS The average follow-up was 5.6 years (range, 2-10.5 years). All patients had a good outcome without related symptoms. No epiphysiodesis, angular deformity or recurrence was observed. One patient with femoral lesion involving the distal medial part of the epiphysis developed, four months after surgical excision, a calcification outside the area of total excision. This calcification did not increase in size at two years follow-up. Another patient with lateral involvement of the proximal tibial epiphysis presented a postoperative nervous complication. Spontaneous nervous recovery occurred three months after surgery. DISCUSSION MRI was useful to find a potential plane of cleavage between the epiphysis and the pathological tissue. We recommend early removing ossifications when a cleavage plane is identified. Waiting a possible complication or increasing of size does not seem logical. Of course, the treatment will be not the same if no cleavage plane is found on MRI. LEVEL OF EVIDENCE IV.

Abstract
Assessment of skeletal age is important in children’s orthopaedics. We compared two simplified methods used in the assessment of skeletal age. Both methods have been described previously with one based on the appearance of the epiphysis at the olecranon and the other on the digital epiphyses. We also investigated the influence of assessor experience on applying these two methods. Our investigation was based on the anteroposterior left hand and lateral elbow radiographs of 44 boys (mean: 14.4; 12.4 to 16.1 ) and 78 girls (mean: 13.0; 11.1 to14.9) obtained during the pubertal growth spurt. A total of nine observers examined the radiographs with the observers assigned to three groups based on their experience (experienced, intermediate and novice). These raters were required to determined skeletal ages twice at six-week intervals. The correlation between the two methods was determined per assessment and per observer groups. Interclass correlation coefficients (ICC) evaluated the reproducibility of the two methods. The overall correlation between the two methods was r = 0.83 for boys and r = 0.84 for girls. The correlation was equal between first and second assessment, and between the observer groups (r ≥ 0.82). There was an equally strong ICC for the assessment effect (ICC ≤ 0.4%) and observer effect (ICC ≤ 3%) for each method. There was no significant (p < 0.05) difference between the levels of experience. The two methods are equally reliable in assessing skeletal maturity. The olecranon method offers detailed information during the pubertal growth spurt, while the digital method is as accurate but less detailed, making it more useful after the pubertal growth spurt once the olecranon has ossified.

Abstract
The aim of this study was to describe the surgical technique of and indications for percutaneous pelvic osteotomy in patients with severe cerebral palsy. Forty non-ambulatory children and adolescents (47 hips) were consecutively treated with percutaneous pelvic osteotomy. The mean preoperative Reimers' migration percentage improved from 66.2% to 4.9% at the final follow-up. The mean preoperative acetabular angle (AA) improved from 32.4° to 13.2° at last follow-up. Percutaneous pelvic osteotomy is a less invasive surgical approach and appears to be a valid option with similar outcomes to standard techniques.This method results in less muscle stripping and blood loss and a shorter operating time.

Abstract
The ideal treatment for traumatic anterior dislocation of the shoulder in the skeletally immature patient is controversial. The aim of this study is to evaluate the outcomes after either conservative and/or surgical treatment using the Latarjet technique. A retrospective series of 49 out of 80 patients were reviewed. We found no significant differences between either treatment method regarding functional scores and pain levels. Although not statistically significant, post-surgical patients showed better signs of shoulder stability than others who have a higher rate of recurrence. Further, 92% of the post-surgical group had returned to the same level of activity versus 52% in the non-surgically treated group. We found no contraindications to operate on a skeletally immature patient. Cite this article: Bone Joint J 2014;96-B:354–9.

Abstract
BACKGROUND Laparoscopic appendectomy is a feasible and safe alternative to open appendectomy for uncomplicated appendicitis. In the past decade several laparoscopic procedures have been described using one or more ports. We report our experience in treating acute appendicitis with one-port transumbilical laparoscopic-assisted appendectomy (TULAA). PATIENTS AND METHODS We performed 231 TULAA on patients in the period from November 2001 to September 2007. We introduced an 11 mm Hasson's port using open technique; an operative channel with 10 mm telescope and an atraumatic grasper were used. After intra-abdominal laparoscopic dissection, the appendix was exteriorised through the umbilical access. The appendectomy was performed outside the abdomen as in the open procedure; the operation was completed using only one port in 227 patients (98%), two and three ports in two patients (1%) while conversion to open surgery was needed in two patients (1%). RESULTS The average operating time was 38 minutes and the median time to discharge was three days. Four (1, 7%) early postoperative complications (two suppuration of the umbilical wound) with no major complications were observed. CONCLUSIONS Our results demonstrate that TULAA, which combines the advantages of both open and laparoscopic procedures, is a valid alternative form of treating uncomplicated appendicitis. If appendectomy cannot be completed with only one port, insertion of one or more ports may be necessary to safely conclude the procedure.

Abstract
AIM The best treatment of non-palpable testes is currently argument of debate. The aim of present study was to describe authors' experience in surgical treatment with inguinal standard orchidopexy of non-palpable testes. METHODS In the last 17 years we have treated 2002 cryptorchid testes, among these 327 (16.33%) were non palpable. Age and distribution of cryptorchid testes was: 0-1 y (165 NPT), 1-2 y (84 NPT), 2-5 y (43 NPT), 5-10 y (16 NPT) and >10 y (19 NPT). RESULTS Non-palpable testes were diagnosed and treated earlier (76.14% in the first two years). At surgical examination 204 (62.38%) were intrabdominal, 80 (24.46%) were atrophic and 43 (13.14%) vanishing. Among atrophic testes 54 (67.5%) were intracanicular, 21 (26.5%) were at the external inguinal ring, 4 (5%) were intrabdominal and 1 (1.25%) ectopic; among vanishing testes 22 (51.16%) were intrabdominal, 14 (32.55%) intracanicular and 7 (16.27%) at the external ring of inguinal canal. CONCLUSION Atrophic and vanishing testes were in intrabdominal location in 26 cases: only in these cases (7.95% of all non palpable testes) laparoscopy should have avoided inguinal surgery. Inguinal standard orchiopexy performed as day-surgery with general anaesthesia associated to caudal analgesia should be considered effective and less invasive than laparoscopic approach.

Abstract
INTRODUCTION Recent data has indicated the usefulness of performing orchiopexy in the first years of life. In this study, we evaluated testicular function in young men operated on for cryptorchidism in the first year of life. To our knowledge, this is the first report on the effects of such an early treatment. MATERIALS AND METHODS Testicular function was assessed in a group of young men operated for cryptorchidism during the first year of life (Group A, n=13) and during the second year of life (Group B, n=16). RESULTS Total sperm counts were clearly higher in Group A (52.3+/-14.3 million/ml vs. 30.4+/-23.5 million/ml, p=0.005) as was sperm motility (36.2+/-8.7 vs. 23.1+/-15.7%, p=0.009). A clear inverse relationship was found between age at orchiopexy and total sperm count (r=-0.394, p=0.034) and sperm motility (r=-0.382, p=0.041). The relationship between volume of testes, position at surgery, uni/bilaterality of cryptorchidism, evidence of Ad spermatogonia at biopsy performed during surgery and treatment with LHRH and hCG performed before surgery and fertility was not significant. The latter findings may be partially explained by the low number of patients participating in the study and need further investigation. CONCLUSIONS We obtained, for the first time, results showing the benefit of treating cryptorchidism during the first year of life rather than in the second year or even later.

Abstract
AIM A retrospective analysis was made to evaluate our experience in the management of tracheobronchial foreign bodies (TFB) in children (age <or= 14 years), underlining the importance of lung scintigraphy in patients' selection. METHODS The authors retrospectively reviewed all pediatric bronchoscopies performed by the bronchoscopic team at their Institution from July 2001 to December 2007 in the suspicion of TFB in children <14 years of age. RESULTS A total of 32 TFB were identified in 25 boys and 7 girls with a mean age of 2.7 years (range, 6 months to 13 years). Diagnostic algorithm included: historical data, clinical evaluation, X-rays and nuclear medicine imaging. Bronchoscopy was performed under general anesthesia only in scintigraphy positive patients. In the procedure, a 2.7 mm pediatric flexible bronchoscope, passed through the endotracheal tube, was used exclusively for demonstrate and localize TFB and a 3.5-4 mm rigid bronchoscope to extract it. Extraction with the rigid bronchoscope was successful in all cases. The average time of the procedure using both instruments was 46 min (range 35 to 200 minutes). There were no complications associated with any of the procedures in these children. CONCLUSIONS Rigid bronchoscopic extraction of paediatric TFB can be performed safely with minimal risks and complications. Careful patient's' selection remains crucial for choosing candidates to bronchoscopy. In our experience scintigraphic evaluation demonstrated to be of great value in order to have a correct pre-endoscopic diagnosis.

Abstract
Joint contractures, subluxation and dislocation are common problem in children with neuromuscular disorders. Medical, surgical and rehabilitative approaches can be used to maintain patient function and comfort. Contracture release, hip dysplasia correction and procedures to address or prevent hip subluxation or dislocation, are not always necessary since patients can be asymptomatic and surgical treatment will not always be successful in maintaining a reduced hip. In fact, controversy surrounds the management of hip disorder in children with Duchenne Muscular Dystrophy, Spinal Muscular Atrophy, Charcot-Marie-Tooth Disease and Arthrogryposis Multiplex Congenita. Patients with neuromuscular disorders also frequently develop a progressive scoliosis with pelvic obliquity which may affect sitting balance and become painful. Most subluxations and dislocations have the tendency to occur on the high side of a tilted pelvis. Spinal stabilisation is sometimes necessary to improve the pelvic tilt and to prevent further increase. The present article provides an overview of the current strategies of hip management in neuromuscular disorders.

Abstract
An extremely rare case of type A esophageal atresia is reported. The baby girl patient born spontaneously after a 38-week pregnancy, was diagnosed prenatally with suspected type A esophageal atresia. Diagnosis was confirmed at birth by chest and abdominal X-ray. As per protocol, a naso-esophageal tube was positioned in aspiration and a Stamm gastrostomy made for nutritional purposes. Evaluation of the distance between blind pouches at one month of life showed they were overlapping. At intervention the pouches were found to be united by a fibrous bridge about 1.5 cm long. Anastomosis was carried out with ease. The postoperative course was trouble-free. On the X day the baby girl was being fed completely per os. Histolo-gical examination of the fibrous residue excluded the presence of a mucosa-lined lumen. X-ray examination of the esophageal-gastric passage, one month after the operation, showed the smooth transit of the contrast medium and an adequate anastomotic lumen. At follow-up, at the age of 9 months, the baby was growing normally and being fed per os with a diet appropriate for her age; no oesophageal dilatation was necessary. Type A oesophageal atresias are long-gap forms: they are treated with direct anastomosis after the blind pouches come together spontaneously in the first four months of life. Stress is laid on the rarity of the case. According to Kluth's classification of 1976, this form was described by Mason in 1855 and Jlott in 1905 on the basis of autopsy findings. A review of the literature did not show any similar clinical cases.

Abstract
Children presenting with Perthes' disease before their sixth birthday are considered to have a good prognosis. We describe 166 hips in children in this age group. The mean age at onset of the disease was 44 months (22 to 72). Mild forms (Catterall I and II) were treated conservatively and severe forms (Catterall III and IV) either conservatively or operatively. The aim of the former treatment was to restrict weight-bearing. Operative treatment consisted of innominate osteotomy and was indicated by a Conway type-B appearance on the bone scan. All the patients were followed to skeletal maturity with a mean follow-up of 11 years (8 to 15). The end results were evaluated radiologically using the classifications of Stulberg and Mose. A total of 50 hips were Catterall grade-I or grade-II, 65 Catterall grade-III and 51 Catterall grade-IV. All hips with mild disease had a good result at skeletal maturity. Of the hips with severe disease 78 (67.3%) had good (Stulberg I and II), 26 (22.4%) fair (Stulberg III) and 12 (10.3%) poor results (Stulberg IV and V). Of the Catterall grade-III hips 38 were treated conservatively of which 31 (81.6%) had a good result, six (15.8%) a fair and one (2.6%) a poor result. Operative treatment was carried out on 27 Catterall grade-III hips, of which 21 (77.8%) had a good, four (14.8%) a fair and two (7.4%) a poor result. By comparison conservative treatment of 19 Catterall grade-IV hips led to ten (52.7%) good, seven (36.8%) fair and two (10.5%) poor results. Operative treatment was carried out on 32 Catterall grade-IV hips, of which 16 (50.0%) had a good, nine (28.1%) a fair and seven (21.9%) a poor result. We confirm that the prognosis in Perthes' disease is generally good when the age at onset is less than six years. In severe disease there is no significant difference in outcome after conservative or operative treatment (p > 0.05). Catterall grade-III hips had a better outcome according to the Stulberg and Mose criteria than Catterall grade-IV hips, regardless of the method of treatment.

Abstract
AIM Macrogol 4,000 is one of the new generation's osmotic laxatives. It is constituted by a heavy molecular weight polymer without additional salts. In most of patients Macrogol 4,000 shows its efficacy in 48 hours from the beginning of treatment. Daily evacuations has been reported after first week therapy with an improvement in quality of life. The aim of this observational study was to demonstrate the efficacy of Macrogol 4,000 in the treatment of constipation in children. METHODS The effect of Macrogol 4,000 was assessed in 120 children affected by constipation treated with therapeutic doses of Macrogol 4,000. The study period ranged from September 2006 to March 2007. The data analysis was collected with the evaluations concerning clinical examination and the consultation of daily diaries assembled by parents, tracking stooling pattern; in case of loosing contacts with the patient, a telephonic survey has been carried out. The child with symptoms improvement, i.e. reduction of the pain during defecation, daily spontaneous evacuations and better stool consistence, were considered ''normal''. RESULTS Of the 120 patients, 89 returned to the clinical follow-up, while the remaining 31, who missed the follow-up, has been contacted by telephone. To the final analysis, 103 patients (85.8%) have had a normalization of the clinical symptoms, 9 patients (7.5%) have refused Macrogol 4,000 for the unpleasant flavour, 8 patients (6.7%) did not have any improvement from the treatment. CONCLUSION The results of this observational study suggest that Macrogol 4,000 could be very useful to treat pediatric patients with constipation, also those affected by neuronal intestinal displasia (NID) type B.

Abstract
Alimentary tract duplications represent rare anomalies, with only 5 % occurring in the rectum. The variety in clinical presentation may lead to a delay in diagnosis or to incorrect and multiple surgical procedures. We report the clinical, histological and immunohistochemical characteristics of a rectal duplication occurring in a 3-month-old male with an unusual clinical presentation. Using routine histology and immunohistochemistry, the rectal duplication showed the diffuse presence of gastric mucosa with a characteristic immunophenotype (i.e., diffuse cytokeratin 7 positivity and scattered chromogranin immunoreactivity). As far as we know, this is the first report showing an immunohistochemical differentiation pattern of gastric lining in a rectal duplication. Our results, showing the presence of gastric mucosa, are suggestive of a possible origin from the embryonic foregut.

Abstract
PURPOSE OF THE STUDY The purpose of this study is to assess the consequences brought by selective dorsal arthrodesis of thoracic spine (T1-T6) to the growth of spine and thoracic volume in operated and sham-operated New Zealand White rabbits, between prepubertal age and the end of somatic growth, through the study of computerised tomography (CT) scans periodically carried out on them after arthrodesis surgery. MATERIAL AND METHODS Nine female rabbits were subjected to surgery for selective dorsal arthrodesis of the upper thoracic spine and three were sham-operated. Surgery was performed at age nine weeks, before the onset of puberty. Two "C"-shaped titanium bars were placed beside the spinous processes of the thoracic vertebrae to obtain a selective posterior arthrodesis of the first six thoracic vertebrae. Under general anesthesia, three CT scans were performed, 10 (t1), 55 (t2) and 139 (t3) days after surgery. Measures were obtained by Myrian Pro software for three different groups: group 1 with complete fusion, group 2 with incomplete fusion, group 3 sham-operated. RESULTS The total dorsal and ventral lengths of thoracic vertebral bodies in the spinal segment T1-T6 was smaller in group 1 and group 2 than in group 3, whereas no differences were observed between the three groups in the T7-T12 segment. The average of the dorsoventral/laterolateral thoracic diameter ratio at fused levels was less than 1 in group 1 as well as in group 2; on the contrary, in group 3 it was greater than 1. The sternum and lung volume grow less. CONCLUSIONS Vertebral arthrodesis in the treatment of progressive idiopathic scoliosis in prepubertal patients is not ideal, but is still a choice in treating major deformities of the spine. Postoperative assessment of spinal deformity is essential, feasible and recordable through CT scans. Dorsal arthrodesis in prepubertal rabbits changes thoracic growth patterns. In operated rabbits, the dorsoventral thoracic diameter grows more slowly than the laterolateral thoracic diameter. The sternum, the total lengths of thoracic vertebral bodies in the spinal segment T1-T6 and lungs grow less. The Crankshaft phenomenon is evident at the fused vertebral levels where there is a reduction of thoracic kyphosis.

Abstract
Our aim was to review the efficacy of the wound vacuum-assisted closure (VAC) system in the treatment of deep infection after extensive instrumentation and fusion for spinal deformity in children and adolescents. A total of 14 patients with early deep spinal infection were treated using this technique. Of these, 12 had neuromuscular or syndromic problems. Clinical and laboratory data were reviewed. The mean follow-up was 44 months (24 to 72). All wounds healed. Two patients required plastic surgery to speed up the process. In no patient was the hardware removed and there was no loss of correction or recurrent infection. We believe that the wound VAC system is a useful tool in the armamentarium of the spinal surgeon dealing with patients susceptible to wound infections, especially those with neuromuscular diseases. It allows for the retention of the instrumentation and the maintenance of spinal correction. It is reliable and easy to use.

Abstract
The concept of conservative clubfoot treatment beginning in the neonatal period has changed considerably in the last 2 decades. The rate of clubfeet requiring surgery (20%) and the extent of surgical interventions have dropped significantly. The early functional Montpellier method has proved to be highly effective for all degrees of deformity. It is used for patients from birth until the age of 1 year. The treatment during the first 3 months of life is decisive and consists of daily physical therapy, use of a continuous passive motion machine, and taping. This method represents an efficient alternative to the popular treatment of serial casting. Nevertheless, conservative clubfoot treatment reaches its limits as the degree of deformity increases and it should be complemented by a selective minimally invasive surgical concept. The technique is described systematically and its current value is discussed.

Abstract
The Sauvegrain et al. method of assessing skeletal age from elbow radiographs is useful during the 2 years of the pubertal growth spurt: between 11 and 13 years in girls and between 13 and 15 years in boys. This method uses four ossification centers of the elbow: lateral condyle, trochlea, olecranon apophysis, and proximal radial epiphysis. It is based on a 27-point scoring system. The scores of these structures are summed, a total score is determined, and a graph is then used to determine the skeletal age. This simple, reliable, and reproducible method complements the Greulich and Pyle atlas, which does not allow assessment of skeletal age in 6-month intervals during the phase of accelerating growth velocity. In clinical practice, maturity can best be evaluated by associating skeletal age, annual growth rate, and Tanner stages. Skeletal age assessment from the elbow is useful to plan the timing of epiphysiodesis in limb length inequality or to evaluate the progression risk of idiopathic scoliosis.

Abstract
BACKGROUND Major limitations of endoscopic retrograde cholangiopancreatography in paediatric populations are a low incidence of biliopancreatic disease among children, the equipment dimensions (size of endoscopes and devices) and the increasing role of MR-cholangiopancreatography in the field of diagnostic indications. Aim of this study was to evaluate the diagnostic and therapeutic yields of endoscopic retrograde cholangiopancreatography for biliopancreatic diseases in a paediatric population. METHODS Between 1996 and 2002, 48 endoscopic retrograde cholangiopancreatographies were performed in 38 children aged 4 weeks to 17 years as part of the diagnostic evaluation for suspected pancreatic or biliary tract disease. Endoscopic retrograde cholangiopancreatography was carried out under general anaesthesia, using prototype paediatric duodenoscopes or standard duodenoscopes in children younger or older than 18 months, respectively. RESULTS The indications to perform endoscopic retrograde cholangiopancreatography were common bile duct stones (14 children), biliopancreatic abnormalities (8), primary sclerosing cholangitis (2), Wirsung disruption (1), biliary leakage (1), cholestasis (4) and pancreatitis (8). Cannulation was successful in all patients but one. Sphincterotomy together with stone extraction or stent insertion was performed in 30/38 patients. Immediate complications were mild and treated conservatively. CONCLUSIONS Diagnostic and therapeutic endoscopic retrograde cholangiopancreatography can be used safely and effectively in the management of biliopancreatic diseases in childhood as well. Indications, endoscopic techniques and complications are similar to those reported for adult patients.

Abstract
A very large H-type rectovaginal fistula was observed in a 9-year-old girl. The diameter of the abnormal opening was about 15 mm. The fistulous tract originated from the stenotic segment 1 cm above the pectinate line of the anus and was connected to the back wall of the vagina. The patient underwent posterior sagittal transrectal surgery with a protecting colostomy. At present, she has good bowel function and sphincter control without recurrence of the fistula.

Abstract
Multiple intestinal atresia is a rare disorder with vascular or hereditary etiology. So far, the occurrence of this malformation along with omphalocele has not been reported. We describe a boy born from a nonconsanguineous gypsy couple with intrauterine growth retardation, omphalocele, and multiple intestinal atresia from the pylorus to the rectum. The microscopic examination of the intestine shows multiple small lumina with a sieve-like appearance. This is characteristic of the hereditary atresias and suggests development of a defect in (re)canalization during embryogenesis. The association with omphalocele indicates a common developmental defect may be present.

Abstract
PURPOSE The aim of the study was to evaluate testicular hormones and sperm counts of young men treated in childhood for cryptorchidism METHODS Testicular volume, serum luteinizing hormone (LH), follicle-stimulating hormone (FSH), and testosterone as well as semen specimens were evaluated in 57 men (mean age, 19 years; range, 18 to 27 years) treated in childhood for unilateral (n = 47) and bilateral (n = 10) cryptorchidism. In 3 unilateral cases monorchidism was found. Thirty-seven patients underwent orchiopexy after hormonal treatment (luteinizing hormone releasing factor, 1.2 mg/d for 28 days followed by human chorionic gonadotropin, 500 IU intramuscularly 3 times a week for 3 weeks). The remainder underwent surgery. Mean age at surgical treatment was 5.4 years (range, 2 to 12 years). These patients were examinated again after a mean period of 13.3 years (range, 10 to 19 years). RESULTS Reduced testicular volume (<12 mL) was found in 6 of 64 testes (9.3%). LH, FSH, and testosterone levels were found within the normal range in all patients. With linear regression, inverse relations were found between FSH and, respectively, testicular volume (P =.002), sperm concentration (P =.013), sperm motility (P =.023), and normally shaped sperms (P =.019). There were direct relations between testicular volume and sperm concentration (P =.02), sperm motility (P =.000), and normally shaped sperms (P =.001). We did not find any statistical correlation between age at surgery and semen quality. Significantly better results in terms of sperm counts were found in patients directly operated on in comparison to those treated with hormones before orchiopexy. CONCLUSIONS Presented data indicate tubular impairment in young men operated on in childhood for cryptorchidism; FSH values increase and testicular volume decrease are related to sperm deterioration. Studies on children treated in the first 2 years of life are required to clarify the usefulness of early treatment of cryptorchidism.

Abstract
The authors report a clinical case of congenital cyst of the pancreas occurred in a female aged 15 months. They stress how this pathology is particularly rare in pediatric age (only 22 cases in the literature) and how it is extremely difficult to formulate a preoperative diagnosis. The young patient was in good general condition with an enormous abdominal tumefaction and without alterations of hematochemical markers. Echographic and tomographic patterns led to four diagnostic hypotheses: a) mesenteric cyst; b) left ovarian cyst or compound ovarian tumor; c) intestinal duplication; d) pancreatic cyst. Only after surgery a correct diagnosis was formulated (on the basis of the topographic position and the intracystic content of amylase and lipase) and a complete resolution of this pathology was obtained. Surgery therefore has the double function of formulating a correct diagnosis and allowing the complete resolution of this pathology. The complete surgical removal of the mass, in view of the benignity of this lesion, is the therapeutic goal.

Abstract
PURPOSE We investigated the efficacy of early gonadotropin treatment of cryptorchidism for promoting testicular descent and ameliorating testicular histology. MATERIALS AND METHODS We treated 319 cryptorchid testes in 281 boys 4 months to 3 years old with luteinizing hormone-releasing hormone and human chorionic gonadotropin sequential therapy. Surgery was done on the 207 testes that did not respond to medical treatment. Microscopic biopsies were performed in 134 of these 207 testes. Histological findings were compared to those of 30 cryptorchid testes in boys younger than 1 year who underwent surgery without previous hormonal treatment. RESULTS Combined luteinizing hormone-releasing hormone and human chorionic gonadotropin treatment induced scrotal descent of a percentage of cryptorchid testes depending on clinical position. Therapeutic success was greater when testes were in a lower position and results were not age dependent. Hormonal treatment of cryptorchidism during the first year of life stimulated spermatogonia maturation. CONCLUSIONS When administered at the end of age 6 months, hormonal treatment can be considered an effective and timely substitution for gonadotropin and testosterone insufficiency in cryptorchid infants. Therefore, we recommend this therapeutic procedure combined with surgery in the first year of life.

Abstract
From 1986 to 1990, 53 non-palpable testes were treated in the department of Pediatric Surgery and Endocrinology at the Regina Margherita Hospital, Turin, Italy. The reported patients were 45, 8 of them were bilateral with both testes non-palpable, 13 of the remaining patients were right cryptorchid and 24 were left. All patients received medical treatment, by LH-RH nasal spray and HCG, before surgery. None of the non-palpable testes descended by hormone therapy only, so that surgical exploration was always required. In the 53 reported cases, 10 gonads were not found, 13 were atrophic and 30 were abdominal. All abdominal gonads were positioned into the scrotum by orchiopexy in a single stage. Half of the patients underwent operation before the age of 2. Therefore, it is to be pointed out that the younger a patient the shorter his inguinal canal, this facilitates orchiopexy for high, undescended testes. In 10 patients a testicular biopsy was made during surgical procedure. Normal morphology and normal spermatogonia content were observed in the abdominal testes of the patients who had reached the age of 1 year. During the follow-up of the reported patients no upward displacement was observed. Eleven patients underwent postoperative testicular ultrasonography which showed that parenchymal structure of the operated testis was normal and the volume of the testis was slightly smaller than normal. Based on their experience, the authors suggest to correct cryptorchidism before the age of one year, surgical procedure follows immediately after ineffective hormone therapy.

Abstract
Cryptorchidism is the most frequent anomaly of an endocrine gland; it entails risks of infertility and testicular cancer. Its pathogenesis is thought to be multifactorial including anatomical and mechanical together with endocrine causes. In the last decades most Authors favoured the hypothesis that some degree of androgen insufficiency during fetal life may play a role in determining testicular maldescent. Morphological alterations have been demonstrated in cryptorchidism testes since birth; both tubular and interstitial damage already can be found in the first months of life. A critical phase in germinal development occurs during the third month when gonadotropin and testosterone postnatal surge induces the first maturational step in germ cells development. In cryptorchid infants, gonadotropin insufficiency at this time reduces germ cells differentiation, leading to progressive germinal decline, which becomes manifest after 12 months of life. In the opinion of some Authors, germinal alteration can be partially reversed by early scrotal reposition of the cryptorchid testes. Hormonal therapy with human chorionic gonadotropin (HCG) and luteinizing hormone releasing hormone (LHRH) has been used in the past decades with variable results. A combination of the two hormones has had a greater effect in inducing testicular descent compared to single hormone treatment. Although some surgeons already treat cryptorchid patients during childhood, an increasing number of pediatric surgeons believe that early treatment, performed during infancy is preferable, when considering the early and progressive histological damage seen in cryptorchid gonads. In our opinion, also hormonal treatment performed during the first year of life seems preferable since it can at the same time induce scrotal descent of cryptorchid testes and substitute postnatal gonadotropin insufficiency.

Abstract
The Authors describe a case of a voluminous trichobezoar in a girl 9 years old. The patient was referred for evaluation of abdominal pain that presented after a banal blunt abdominal trauma occurred some days earlier. On physical examination an epigastric mass was detected. For a few days the girl suffered of inappetence and postprandial vomit. She was noted to have thin and sparse hair, thin eyebrows and onychodysplasia: these findings were considered as features of cutaneous adnexa dystrophy. The blood test and other laboratory findings were within normal limits. Abdominal US and UGI series failed to detect the nature of the mass. Therefore the patient underwent gastroscopy that showed a voluminous trichobezoar, so big and hard that gastrotomy was required for removal. The weight of the mass was 700 g; it occupied the whole stomach from fundus to pylorus. Postoperative recovery was uneventful. After discharge the patient was referred to the Neuropsychiatric Service for treatment trichophagia and prevention of recurrence. The most common site of trichobezoar is stomach. Clinical findings are often aspecific. US and UGI series may not allow the correct diagnosis. A rational diagnostic suspicion can arise when alopecia circumscripta is present. Endoscopy remains the elective technique: this procedure can be contemporarily diagnostic and therapeutic. Surgical approach is required only in case of trichobezoar with peculiar size, shape and hardness. We feel that a neuropsychiatric support is necessary to avoid recurrence.

Abstract
In 238 boys with cryptorchidism, between the ages of 4 and 48 months, luteinizing hormone releasing hormone (LHRH) was administered as nasal spray 1.2 mg/day for 4 weeks. The nonresponders received human chorionic gonadotropin (HCG) 500 I.U. i.m. three times a week for 3 weeks. With the combined treatment 37.8% of testes descended into the scrotum. Testicular descent occurred more often in patients whose testes were located in a lower position. Histological findings indicated a reduction in the number and maturation of germ cells. A clear improvement of germ cells trophism was observed in boys hormonally treated and operated on before the 12th month of life. Early administered combined treatment with LHRH and HCG can be considered as a substitution of the gonadotropins insufficiency manifested by most cryptorchid infants in the first months of life.

Abstract
In the last 12 years, 916 cryptorchid testes have been treated sequentially with therapeutic and surgical procedures. Although the age of the boys varied considerably at the time that corrective procedures commenced, the best results were obtained when they were in the first year of life. The testes of the boys at this age who had been treated had a normal histology; this was not the case of those who were treated at an age older than one year.

Abstract
A retrospective study was performed over the children admitted to three regional pediatric burn units, over a 5-year period (1986-1990). Out of 695 pediatric patients, 270 (38.8%) were admitted with burns of the head and neck. This whole childhood age group (up to 14 years of age) was examined epidemiologically. The age group presenting the highest incidence was within 0-3 years (71%); scalds were involved in high percentage (68%) and many injuries occurred at home (93%). Epidemiological aspects of the report are discussed with particular consideration of preventive programs.
