Abstract Background Survivors of heritable retinoblastoma carry a high risk to develop second cancers. Eye‐preserving radiotherapy raises this risk, while the impact chemotherapy remains less defined. Procedure This population‐based study characterizes all treatment modalities on cancers incidence and type after in Germany. Data cancer 648 patients with treated between 1940 2008 at German national reference center for were analyzed identify associations treatment. Results The cumulative...

Background Familial hemophagocytic lymphohistiocytosis is a genetic disorder of lymphocyte cytotoxicity that usually presents in the first two years life and has poor prognosis unless treated by hematopoietic stem cell transplantation. Atypical courses with later onset prolonged survival have been described, but no detailed analysis immunological parameters associated typical versus atypical forms familial performed.Design Methods We analyzed disease manifestations, NK-cell T-cell...

Juvenile Paget's disease (JPD) is an extremely rare, yet painful and debilitating bone with onset occurring during early childhood. JPD can be caused by loss of function osteoprotegerin, resulting in subsequent stimulation osteoclasts via the receptor activator nuclear factor-κB (RANK) pathway. Increased turnover lack modeling lead to severe deformities, frequent fractures, short stature, hearing.The treatment for challenging has previously been based on administration either calcitonin or...

Purpose Intraocular retinoblastoma is curable, but survivors with a heritable predisposition are at high risk for second malignancies. Because malignancies associated mortality, prognostic factors malignancy influence long-term overall survival. This study investigates the impact of all types eye-preserving therapies on survival in complete German cohort patients retinoblastoma. Patients and Methods Overall survival, disease staging using international scales, time period diagnosis,...

Introduction Suspected osteopathology in chronically ill children often necessitates the assessment of bone mineral density. The most frequently used methods are dual-energy X-ray-absorption (DXA) and peripheral quantitative computed tomography (pQCT). BoneXpert software provides an automated radiogrammatic method to assess skeletal age from digitalized X-rays left hand. Furthermore, program calculates Bone Health Index (BHI), a measure cortical thickness mineralization, which is obtained...

Introduction Sickle cell anemia and thalassemia result in impaired bone health both adults youths. Children with other types of chronic hemolytic may also display health. Study Design To assess pediatric patients anemia, a cross-sectional study was conducted involving 45 different forms (i.e., 17 homozygous sickle disease 14 hereditary spherocytosis patients). Biochemical, radiographic anamnestic parameters were assessed. Results Vitamin D deficiency 25 OH-vitamin serum levels below 20 ng/ml...

Survivors of childhood cancer frequently suffer from endocrine late effects, which are, at least partly, attributed to toxic effects chemotherapy. Treatment retinoblastoma typically involves chemotherapy a very young age. The authors conducted cross-sectional study assess bone health in pediatric cohort 33 survivors (mean age: 4.4 years) who had undergone treatment an especially age 0.76 years). Of these patients, 14 unilateral and 19 bilateral retinoblastoma. Polychemotherapy consisted with...

Abstract Introduction: Juvenile Paget’s disease (JPD), an ultra-rare, debilitating bone due to loss of functional osteoprotegerin (OPG), is caused by recessive mutations in TNFRFSF11B. A genotype–phenotype correlation spanning from mild very severe forms described. Aim: This study aimed describe the complexity human phenotype OPG deficiency more detail and investigate heterozygous mutation carriers for clinical signs JPD. Patients: We investigated 3 children with JPD families Turkish,...

Childhood cancer entails a heavy burden for patients and their families. Recent advances in overall survival rates have increasingly brought long-term quality of life into focus. Animal-assisted activities (AAAs) long been hypothesized to alleviate the on pediatric peers hospital setting. However, use inpatient oncology has sensitive issue mainly due fear infections, resulting lack studies. This study presents data feasibility, safety, efficacy AAAs from single German center.

Background: Impaired bone health is a late effect of childhood malignancies which can be difficult to detect in juvenile survivors. It may, however, lead compromised quality life, or even permanent disability later life due osteoporosis, pain fractures if left untreated.

Abstract Biallelic germline mutations in BRCA2 occur the Fanconi anemia (FA)-D1 subtype of rare pediatric disorder, FA, characterized clinically by severe congenital abnormalities and a very high propensity to develop malignancies early life. Clinical genetic data from 96 FA-D1 patients with biallelic were collected used new cancer risk prediction score system based on specific BRCA2. This takes into account location frameshift/stop missense relative exon 11 BRCA2, which encodes major sites...
