RESUMO
BACKGROUND: Malformations are the most common cause of death in infancy. Numerous studies indicate an increased prevalence of malformations in neonates in recent years in some countries around the world. This study analyzed local and national trends of the prevalences of gastroschisis, omphalocele, spina bifida and orofacial clefts during 2000 till 2010 in Leipzig, Saxony, Saxony-Anhalt and Germany. METHODS: The prevalence of neonatal malformations was studied retrospectively from January 2000 till December 2010 using 4 sources from Leipzig, Saxony, Saxony-Anhalt and Germany. RESULTS: Between 2000 and 2010, the prevalence in Germany and in Saxony, respectively was 1.97/2.12 (gastroschisis), 1.63/1.48 (omphalocele), 5.80/8.11 (orofacial clefts) and 2.92/2.50 (spina bifida) of 10 000 live births. In Saxony, a small increase in prevalence was detected (OR/year: 1.01-1.09). In Germany, the prevalence of malformations also increased significantly (OR/year: 1.01-1.04) with the exception of the prevalence of spina bifida which seemed to decline (OR/year 0.986 (0.97-1.0), p-adjust=0.04). CONCLUSION: Whether or not there has been an actual increase in the prevalence of neonatal malformations in Germany over the years or the apparent increase is just due to bias, coding errors, multiple reporting and/or false registration and codification remains unclear. Importantly, in Germany, since prevalence of malformations is monitored prospectively only in Saxony-Anhalt and Rhineland-Palatinate, only in these states is it possible to recognize recent changes. For early identification of changes in prevalence and timely implementation of preventive measures, a nationwide register or additional regional registers are deemed necessary.

BACKGROUND: Slipped capital femoral epiphysis (SCFE) is a multifactorial structural loosening in the area through the epiphyseal plate between the epiphysis and metaphysis accompanied by slippage of the femoral head in the mid-dorsal-caudal direction without additional adequate trauma. In this retrospective study, all patients with chronic SCFE were assessed who had been treated by implanting a dynamic epiphyseal telescopic (DET) screw. METHODOLOGY: All patients who had been treated at our hospital with a DET screw implant between December 2006 and November 2014 following diagnosis of chronic SCFE were included in the study. Clinical and radiological follow-up was carried out after 6 weeks, 12 weeks, and then every 6 months. RESULTS: In all patients, the SCFE proved to have been firmly fixed and no further slippage was observed in any patient on the side affected. None of the prophylactically treated hips showed secondary SCFE either. In all patients, the DET screw led to partial remodeling of the slippage. The average slippage angle according to Southwick (epsilon angle) was about 30° preoperatively and about 19° in the most recent radiological follow-up. The alpha angle according to Nötzli was about 91° preoperatively and about 62° in the most recent radiological follow-up. Most of the patients showed none treatment-related dysfunction. CONCLUSION: Surgical treatment with a DET screw seems to be a safe procedure for both the affected hip and the hip to be treated prophylactically. This method is an adequate alternative to the widespread technique of pinning with Kwires.

PURPOSE: To determine the importance of MRI with contrast-enhanced MRA for the detection or exclusion of aberrant or obstructing renal arteries in ureteropelvic junction obstruction in children. MATERIALS AND METHODS: Key word-based search in RIS database (ureteropelvic junction obstruction/ MRI) and retrospective comparison of arterial findings from preoperative contrast -enhanced MRA and intra-operative inspection. From 2007 to 2013, 19 children with ureteropelvic junction obstruction underwent contrast-enhanced MRA. Based on the results of the MRI scan and MAG3 scintigraphy, the children were referred to surgery (Anderson-Hynes-pyeloplasty). RESULTS: An aberrant renal artery was diagnosed with MRI in 14 of 19 children, and intra-operative inspection confirmed 13 of those 14. In the remaining 5 children, no aberrant vessel could be observed in MRI and this was confirmed intra-operatively in 3 of the 5 cases, while in the remaining 2, an aberrant vessel was found. Of the 14 children with aberrant vessels, 12 underwent surgery due to assumed ureteral obstruction, which was confirmed by surgery in 11 cases. In one case, an aberrant artery was found intra-operatively, but obstruction could not be confirmed. In one of the 14 children, the vessel was found in MRI, but its obstructing character was negated via MRA, which was confirmed intra-operatively. In the diagnosis of aberrant and obstructing renal arteries, contrast-enhanced MRA presents 85% sensitivity and 80% specificity, with a positive predictive value of 0.8. CONCLUSION: MRI with contrast-enhanced MRA is suitable to detect aberrant and obstructing renal arteries. An obstructive effect of the aberrant vessel is to be assumed if the vessel has a close relationship to the ureteropelvic junction and if it is linearly stretched. KEY POINTS: ⢠MRI with contrast-enhanced MRA is a sure method for the detection of aberrant renal arteries in children with ureteropelvic junction obstruction. ⢠The obstructive effect of the aberrant vessel can be derived from the close proximity of the vessel to the ureteropelvic junction and from the streched course of the vessel.

BACKGROUND: The development of new resources, such as surgical techniques and approaches, results in continuous modification of surgery. To assess these modifications, it is necessary to use measures that quantify the impact of resources on surgical processes. OBJECTIVES: The objective of this work is to introduce and evaluate distance measurements that are able to represent differences in the courses of surgical interventions as processes. METHODS: Hence, we present four different distance measures for surgical processes: the Jaccard distance, Levenshtein distance, Adjacency distance, and Graph matching distance. These measures are formally introduced and evaluated by applying them to clinical data sets from laparoscopic training in pediatric surgery. RESULTS: We analyzed the distances of 450 surgical processes using these four measures with a focus on the difference in surgical processes performed by novices and by experienced surgeons. The Levenshtein and Adjacency distances were best suited to measure distances between surgical processes. CONCLUSION: The measurement of distances between surgical processes is necessary to estimate the benefit of new surgical techniques and strategies.

The laparoscopic paradigm to place different ports according to ergonomic principles is presently challenged by laparoendoscopic single site surgery (LESS). Its objective is to perform a complex task with several instruments using only one access. However, this approach introduces distinct ergonomic problems and requires innovative technical solutions to allow for more complex surgical tasks. In paediatric surgery, this development has just begun. A 16-year-old girl presented with a symptomatic cholecystolithiasis. A multi-channel TriPort (Advanced Surgical Concepts) was introduced through a 20 mm umbilical incision for LESS cholecystectomy. Retraction of the gallbladder was facilitated by a straight grasper, which was inserted transabdominally. For exposition and triangulation a pre-bend dissector (5 mm, Olympus) was employed. Thus, the cystic duct and artery could be exposed, clipped (5mm) and divided. Finally, the gallbladder was dissected from its bed and extracted into a specimen bag. Operating time was 90 minutes and no intra- or postoperative complications occurred. In conclusion, a multi-channel port and angulated instruments during LESS cholecystectomy provided ergonomics close to conventional laparoscopic surgery. For smaller children though, this technology will have to be adapted to their geometry. Finally, even though LESS seems attractive, the present euphoria should not turn into scientific acceptance, until more experience is available and valid data have proven a benefit for patients of any age.

Patients with dysgenetic gonads carry a high risk for the development of gonadal neoplasia. The aim of the study is to evaluate indications and feasibility of laparoscopy and video-assisted prophylactic gonadectomy in children with Ullrich Turner syndrome (UTS) or 46,XY gonadal dysgenesis (GoDy). Between 1996 and December 2002 five girls with UTS and nine patients with 46,XY GoDy (female gender role) were explored by laparoscopy. Video-assisted salpingo-oophorectomy or gonadectomy was performed using a three-port technique. Prophylactic salpingo-oophorectomy was exclusively performed in UTS patients with proven presence of translocated parts of the Y chromosome. In three patients with 46,XY GoDy laparoscopy was followed by surgical revision of the groin and open gonadectomy in four patients. In two cases with UTS the removed streak gonads contained small unilateral tumours stage pT1a, and in four cases of 46, XY GoDy histopathological investigation revealed bilateral neoplasms stage pT1b. We found the following tumour types: gonadoblastoma, dysgerminoma, testicular intraepithelial neoplasia, and mature teratoma. In conclusion, investigative laparoscopy gives a good image of the internal genital structures and allows the safe removal of the dysgenetic gonads during the same operation. The high rate of gonadal tumours underlines the indication for early gonadectomy in these patients.

Long bone fractures combined with joint injuries run a high risk of destabilising the articulations. Remaining joints incongruence can lead to early arthosis especially in cases of severe injuries or not achieved anatomical reduction. A number of osteosynthesis methods are available for anatomical repair of the articular facet. This report presents a seven years old boy with an open comminuted fracture of the distal femur and consecutive joint instability, treated with a Transfixation (Orthofix) of the knee joint. The functional results suggest this method as an alternative treatment.

The versatile Orthofix modular system can be used to treat long-bone fractures in children from the 2nd year of life. It allows definitive fracture management over a short period of time without traumatizing the soft tissues. The possible early mobilization and full weight-bearing mean that the children are able to return early to school or kindergarten. The method enables the stabilization of open fractures with or without excessive soft tissue injury as well as secondary callus distraction. There is no need for a second surgical intervention and no prolonged period of physiotherapy. This fracture treatment suits children's needs and maintains their quality of life.

A retrospective analysis of 332 children with osteomyelitis (OM), managed from 1966 to 1996, was undertaken to evaluate etiology, clinical course and treatment results. In 64% of all patients positive bacterial cultures were obtained, Staphylococcus aureus, streptococci, pneumococci, and Haemophilus influenzae were the most frequently cultured pathogens. In two-thirds of the cases long bones (femur, tibia, humerus) were affected. Osteoarthritis or suppurative arthritis was evident in 27%; 32 of 170 (19%) re-evaluated patients had moderate or severe sequelae. Risk factors for an unfavorable course were the onset of disease in early infancy, suppurative arthritis, and an affected epiphysis. Suppurative arthritis, in particular, needs early evacuation to prevent sequelae. In recent years we observed an increasing number of patients presenting with atypical forms of OM. Since 1989 10 patients were considered to have chronic recurrent multifocal OM (CRMO). In 6 of them the clavicle was involved; their ages ranged from 3 to 14 years. The erythrocyte sedimentation rate was elevated (median 48, range 9-110 mm), while other inflammatory parameters like C-reactive protein (median 9, range <5-85 mg/l) or leucocyte count were slightly elevated or normal. Histopathology was stage-dependent, with a predominance of lymphoplasmacellular infiltration. A nonbacterial origin of CRMO is probable but not proven. Histopathology is not suitable for differentiation between bacterial and nonbacterial forms of bone inflammation.

Circulatory disturbances of the upper extremities may be affected by blockade of the ganglion stellatum. This blockade is possible by electrical stimulation with pocket stimulators. Frequent blockades of the ganglion stellatum are possible, simple, free from pain and without drugs. Rheographic resurges and check up with skin thermographie will demonstrate the effectiveness of this method.
