[Diagnostic imaging in cases of suspected child abuse--focus craniocerebral trauma divergent guidelines and resulting problems]. / Bildgebende Diagnostik bei Verdacht auf Kindesmisshandlung--Fokus Schädel-Hirn-Trauma. Divergente Vorgaben und daraus resultierende Probleme.

For the clinical diagnosis of non-accidental craniocerebral trauma in children there are different recommendations and guidelines, which are not completely consistent. Depending on the examiner, the focus may be on therapeutic relevance, minimization of the exposure to radiation or potential conclusions as to the course of events. Under certain circumstances it may be difficult for the responsible institution to deal with all three perspectives, as is shown by the presented case. From the authors' point of view it would be desirable to work out a common guideline taking into account paediatric radiological and medicolegal aspects.

A Comparison of Familial and Sporadic Type 1 Diabetes Among Young Patients.

OBJECTIVE: To investigate natural course, treatment, and outcomes in familial versus sporadic type 1 diabetes. RESEARCH DESIGN AND METHODS: In a population-based study, we compared patients with onset of type 1 diabetes before the age of 20 years who had a first-degree relative with type 1 diabetes (familial diabetes) with patients with type 1 diabetes who had no first-degree relative with type 1 diabetes (sporadic diabetes) at diagnosis and over the first 10 treatment years, using multivariable regression and proportional hazards models. Patients were identified from the Diabetes Prospective Follow-up Registry (DPV) between 1995 and 2018. RESULTS: Of 57,371 patients with type 1 diabetes, 53,606 (93.4%) had sporadic diabetes and 3,765 (6.6%) had familial diabetes. Familial diabetes, compared with sporadic diabetes, was associated with younger age (median 7.9 vs. 9.7 years, P < 0.001), lower prevalence of ketoacidosis (11.9% vs. 20.4%, P < 0.001), and lower HbA1c levels (9.7% vs. 11.1%, P < 0.001) at onset and higher prevalence of associated autoimmune disease (16.7% vs. 13.6%, P < 0.001). Over 10 years, patients with familial diabetes, in comparison with sporadic diabetes, more often used insulin pumps (P < 0.001) and had a lower rate of severe hypoglycemia (12.97 vs. 14.44 per 100 patient-years, P < 0.001) but similar HbA1c levels (P ≥ 0.08) and ketoacidosis rates (1.85 vs. 2.06 per 100 patient-years, P = 0.11). In familial and sporadic diabetes, absence of ketoacidosis at onset predicted fewer events of severe hypoglycemia (hazard ratio [HR] 0.67, P < 0.001, and 0.91, P < 0.001, respectively) and of ketoacidosis (HR 0.64, P = 0.007, and 0.66, P < 0.001, respectively) after 10 years. CONCLUSIONS: Familial type 1 diabetes, compared with sporadic type 1 diabetes, is characterized by earlier disease manifestation and higher autoimmune comorbidity as well as less metabolic decompensation at onset, likely related to higher disease awareness in affected families, while the course of disease is similar. These findings may have implications for the generalizability of results of diabetes prevention trials from patients with familial type 1 diabetes to patients with sporadic type 1 diabetes.
