Radiotherapy and long-term sequelae in pediatric patients with parameningeal rhabdomyosarcoma: Results of two Cooperative Weichteilsarkom Studiengruppe (CWS) trials and one registry.

Background: Parameningeal location of rhabdomyosarcoma (PM RMS) is known to be an unfavorable prognostic factor. Scarce data are available on radiotherapy (RT) concepts with regard to outcome.

Methods: Treatment and outcome of 395 children with PM RMS registered within two Cooperative Weichteilsarkom Studiengruppe (CWS) trials and one registry (1995-2021) were evaluated.

(p)ppGpp and moonlighting RNases influence the first step of lipopolysaccharide biosynthesis in .

The outer membrane (OM) protects Gram-negative bacteria from harsh environmental conditions and provides intrinsic resistance to many antimicrobial compounds. The asymmetric OM is characterized by phospholipids in the inner leaflet and lipopolysaccharides (LPS) in the outer leaflet. Previous reports suggested an involvement of the signaling nucleotide ppGpp in cell envelope homeostasis in .

Esophageal Diameter as a Function of Weight in Neonates, Children and Adolescents: Reference Values for Dilatation of Esophageal Stenoses.

Introduction: Esophageal stenoses are frequent complications after esophageal atresia surgery as well as after acid, alkali and battery ingestion. Worldwide, repeated balloon dilatations are the most frequently performed procedures for these stenoses. In most cases the stenoses can be dilated sufficiently to allow adequate enteral nutrition.

The Diagnosis and Treatment of Rheumatoid and Juvenile Idiopathic Arthritis of the Temporomandibular Joint.

Background: Involvement of the temporomandibular joint can be shown in 40-90% of patients with rheumatoid arthritis and juvenile idiopathic arthritis (JIA), although it is often asymptomatic. Restricted jaw mobility and jaw pain can be found in approximately 20% of patients with JIA (prevalence: 70 per 100 000 persons). Early diagnosis and treatment of the underlying disease are essential for a good outcome, but uniform, consensus-based management is still lacking.

Mimicry of lyme arthritis by synovial hemangioma.

To report on the differential diagnosis of lyme arthritis and synovial hemangioma due to similar clinical and radiological signs and symptoms. A 15-year-old boy presented at the age of 9 with recurrent rather painless swelling of the right knee. Altogether four episodes lasting for 1-2 weeks each occurred over a period of 18 months before medical advice was sought.
