Summary In recent years, our knowledge of congenital melanocytic nevi (CMN) has greatly expanded. This has led to a paradigm shift. The present article represents a commentary by an interdisciplinary group of physicians from German‐speaking countries with extensive experience in long‐term care and surgical treatment of children and adults with CMN (CMN surgery network, “Netzwerk Nävuschirurgie”, NNC). The authors address aspects such as the indication for treatment as well as treatment planning and implementation under these new premises. Adequate counseling of parents on conservative and/or surgical management requires an interdisciplinary exchange among physicians and individualized planning of the intervention, which frequently involves a multi‐stage procedure. Today, the long‐term aesthetic outcome is at the center of any therapeutic endeavor, whereas melanoma prevention plays only a minor role. The premise of “removal at any cost” no longer holds. Potential treatment‐related adverse effects (hospitalization, wound healing disorders, and others) must be carefully weighed against the prospects of a beneficial outcome. In this context, the use of dermabrasion in particular must be critically evaluated. At a meeting of the NNC in September 2018, its members agreed on a consensus‐based position on dermabrasion, stating that the procedure frequently leads to impaired wound healing and cosmetically unfavorable or hypertrophic scarring. Moreover, dermabrasion is considered to be commonly associated with considerable repigmentation that usually occurs a number of years after the procedure. In addition, the NNC members saw no benefit in terms of melanoma prevention. In the future, physicians should therefore thoroughly caution about the potential risks and often limited cosmetic benefits of dermabrasion.

IntroductionIsolated fallopian tube torsion as a complication of a preexisting hydrosalpinx is a rare finding in pediatric patients. The obvious rarity of this condition, its subtle diagnostic features and dissonant previous reporting about the appropriate therapeutic approach according to age, future conception capacity and potential complications of possible pregnancies make the decision about which surgical approach to use very difficult. In this report, we describe the case of a patient with such a presentation and review the literature. Very few similar reports of neosalpingostomy in pediatric patients have been published to date.Case presentationIn our present report, we describe the case of an 11-year-old Caucasian prepubertal girl who presented to our hospital with complaints of abdominal pain in the right lower quadrant, nausea and vomiting. The diagnostic workup led us to conclude that she had a torsion of the right ovary, which was cystically altered. Exploratory surgery revealed a partial hydrosalpinx and consecutive isolated torsion of the fimbrial part. The proximal isthmic part of the fallopian tube was intact and vital. Restorative surgery was performed to create a neosalpingostomy on the viable isthmic part of the tube and remove the cystic and twisted fimbrial and infundibular parts.ConclusionThe surgical procedure described in this report is technically simple and feasible, but leaves doubts about the final outcome.

Introduction Fractures of the phalanges in children can often be underappreciated by the physician of first contact. Therefore it is necessary to point out which of these fractures, because of the risk of possible future complications, need special mention. Materials and Methods A retrospective review of 512 fractures of the phalanges in children and adolescents during an one year period. Fractures were subdivided into the following categories – physeal fractures, intraarticular (phalangeal neck and condylar) fractures, shaft fractures, tuft fractures, “mallet finger” fractures, volar plate avulsion injuries and collateral ligament avulsion injuries. Main outcome measures was the necessity for operation while the average age at which the injury has occured, the cause of the injury, the frequency of injury of each finger, the necessity for reduction, and the duration of splinting were the secondary outcome measures. Results Collateral ligament avulsion injuries and intraarticular (phalangeal neck and condylar) fractures were injuries which most often necessitated operative treatment. Physeal injuries were the most common injuires with avulsions of the volar plate being the second most common. Accidents during sport was by far the most common cause of injuires in all categories apart from tuft injuries. Conclusion The findings regarding the incidence and the cause of these injuries in this study support the already published dana in the literature. The physician of first contact has to be capable to recognise the problematic fractures – intraarticular (phalangeal neck and condylar), significantly displaced Salter-Harris type III and IV fractures and collateral ligament avulsion injuries and Seymour fractures.

Zusammenfassung In den letzten Jahren hat sich unser Wissensstand zu kongenitalen melanozytären Nävi (KMN) stark erweitert. Die Autoren, eine interdisziplinäre Gruppe von Ärzten und Ärztinnen mit umfangreicher Erfahrung in der Langzeitbetreuung und chirurgischen Therapie von Kindern und Erwachsenen mit KMN (Netzwerk Nävuschirurgie, NNC), geben hier eine Stellungnahme zur Indikationsstellung, Planung und Durchführung einer Behandlung unter diesen neuen Prämissen ab. Die Beratung der Eltern zum konservativen und/oder operativen Management von KMN muss im interdisziplinären Austausch stattfinden und zu einer individuellen Planung des oft mehrstufigen Prozesses führen. Hierbei steht das ästhetische Langzeitergebnis, nicht die Melanomprophylaxe, im Mittelpunkt. Bei keinem KMN gilt die Prämisse der „Entfernung um jeden Preis“. Mögliche therapiebedingte Nebenwirkungen (Hospitalisation, Wundheilungsstörungen etc.) müssen sorgfältig mit den Erfolgsaussichten abgewogen werden. Unter diesen Gesichtspunkten ist insbesondere die Methode der Dermabrasion zu hinterfragen. Auf einer Tagung des NNC im September 2018 wurde eine konsentierte Wertung erarbeitet, nach der die Dermabrasion häufig zu Wundheilungsstörungen sowie zu kosmetisch ungünstiger oder hypertropher Narbenbildung führen kann und sehr häufig mit einer oft erst Jahre später auftretenden Repigmentierung assoziiert ist. Zudem ist kein Nutzen im Sinne einer Melanomprophylaxe erkennbar. Daher sollte in Zukunft sorgfältig auf die möglichen Risiken und den oft limitierten kosmetischen Nutzen der Dermabrasion hingewiesen werden.

The objective of this study was to assess whether the positioning of the wrist joint in the cast in such a manner that it counteracts the direction of angulation of fragments is more important than the cast index in the prevention of secondary displacements in distal forearm fractures. A retrospective review of all pediatric patients (0–16 years of age) who were hospitalized in our institution with displaced fractures of the distal forearm (either isolated fractures of the distal radius or both bone fractures) who underwent subsequent closed reduction and splinting in the period from August 2018 to October 2020. Patients with physeal fractures and open fractures, and skeletally mature patients were excluded from the study. Patients were divided into two categories – the first one in which the cast index was below 0.9 and the second in which it was above 0.9. In each category, we have identified two groups of patients – the first one in whom the wrist joint was positioned in such a manner that it counteracts the direction of angulation of fracture fragments and the second one in whom the wrist joint was in a neutral position. The two groups in each category have been compared according to age, sex, initial angulation, fracture type (isolated radius or both bone fractures), displacement type (angulation or complete dislocation) and the rate of secondary displacement. In both categories, the two groups were comparable according to age, sex, initial angulation, fracture and displacement type. In both categories (cast index below 0.9 and cast index above 0.9), a statistically significant higher portion of patients with secondary displacement was identified in the group of patients who had the wrist joint in a neutral position (Z = −2.1997; P = 0.0278 – for cast index <0.9 and Z = −2.1672; P = 0.030216 for cast index >0.9). Our research supports the notion that positioning of the wrist joint in the position that counteracts the force that leads to angulation of fracture fragments is more important than the cast index in the prevention of secondary displacements in pediatric distal forearm fractures.
