Urinary Microbiota of Healthy Prepubescent Girls and Boys—A Pilot Study
The urine of healthy prepubescent children contained various aerobic-anaerobic combinations of microorganisms. Their diversity in the urine of girls and boys did not differ significantly. However, the level of α-diversity of microorganisms was higher in girls than in boys. We noted differences in the prevalence of certain taxa of microorganisms in the urine of boys and girls. Our study showed a close functional relationship between aerobic and an…
Abdominal Cryptorchidism with Complete Dissociation between the Testis and Deferent Duct Mimicking Testicular Regression Syndrome
Complete separation of the deferent duct from the epididymis in cryptorchid testes residing in the abdomen is an extremely rare variant of developmental disorders of the testis and epididymis. Available sources mention only three clinical cases similar to our observations. The unique anatomic aspects of this disorder hamper the correct diagnosis of an intra-abdominal cryptorchid testis. Two boys with nonpalpable left-sided cryptorchidism underwen…
Diametaphyseal Distal Forearm Fractures in Children
Diametaphyseal forearm fractures are difficult to treat because standard methods for long-bone fracture stabilization in the metaphyseal or diaphyseal regions are less effective in this transition zone. We hypothesized that there is no difference in outcomes between conservative and surgical treatment of diametaphyseal forearm fractures. This retrospective analysis included 132 patients who had undergone treatment for diametaphyseal forearm fract…
Non-Inferiority of Point-of-Care Ultrasound Compared to Radiography to Diagnose Upper Extremity Fractures in Children
Conventional X-ray imaging for fracture diagnosis is time-consuming and exposes patients to ionizing radiation. Additionally, the positioning of the injured limb for standardized X-ray imaging is painful. Point-of-care ultrasound (POCUS) is increasingly available in medical offices and emergency rooms. This study aimed to prove the non-inferiority of POCUS compared to X-ray imaging with respect to diagnostic sensitivity, pain, and investigation t…
Supracondylar Fractures of the Humerus
Supracondylar humerus fractures (ScHF) account for 60% of fractures of the elbow region in children. We assessed the relationship between neurovascular complications and the degree of fracture displacement as rated on the basis of modified Gartland classification. Moreover, we aimed to evaluate predisposing factors, e.g., age and gender, and outcomes of neurovascular complications in ScHF. Between 2004 and 2019, we treated 329 patients with ScHF …
Pocus Diagnosis of Sternal Fractures in Children without Direct Trauma—A Case Series
Sternal fractures in children are rare and tend to be caused by high-energy injury. However, sternal fractures may also be caused by minor and indirect trauma and might therefore not be as rare as previously stated. Ultrasound examination is the method of choice for the diagnosis of sternal fractures. We present three cases of sternal fractures not caused by direct trauma that were presented to our A&E department within a period of only 62 days. …
Differences between Two Methods to Stabilize Supramalleolar Osteotomies in Children—A Retrospective Case Series
Supramalleolar osteotomy (SMO) in pediatric patients can be fixed in various ways. We analyzed the records of 77 pediatric patients (124 SMOs) aged ≤16 years. In 56 patients (96 SMOs), K-wires were used to stabilize SMOs (WF group), while 21 patients (28 SMOs) were treated with locking compression plates (LCPs; PF group). We recorded time to radiographic consolidation, rate of complications, length of hospital stay (LOS), and time to implant remo…

Primary Transverse Closure Compared to Open Wound Treatment for Primary Pilonidal Sinus Disease in Children
We aimed to compare the outcome of two different operative methods to correct pilonidal sinus disease (PSD) in children, i.e., excision and open wound care (OW) versus excision and primary transverse closure (PC) of the wound. In this retrospective, observational study, we extracted data from the medical records of 56 patients who underwent surgery for PSD at our institution between 1 January 2006 and 31 December 2016. To test whether the primary…
Pain during Cast Wedging of Forearm Shaft and Distal Forearm Fractures in Children Aged 3 to 12 Years—A Prospective, Observational Study
Cast wedging improved the position of forearm fracture fragments at the expense of minimal short-term pain
Using students’ feedback for teacher education
Comparing self-perceived quality of teaching to students’ perception can be used in higher education to improve the quality of teaching of pre-service teachers in teacher education. However, comparing these measurements from different perspectives is only meaningful if the same constructs are being measured. To shed light on this comparison’s meaningfulness, we scrutinised whether aspects of quality of teaching are measured in the same way across…
Klassenführung auf der Sekundarstufe II
In einer Studie an Handelsakademien, in die 75 Lehrpersonen und deren Schülerinnen und Schülern einbezogen waren, wurde untersucht, welche Strategien der Klassenführung dazu beitragen, dass Schülerinnen und Schüler gut mitarbeiten und der Unterricht wenig durch Störungen belastet wird. Dabei stellten sich Merkmale der Unterrichtsgestaltung, der Förderung sozialer Beziehungen und der Verhaltenskontrolle als bedeutsam heraus. Das Verhalten erfolgre…
