Prenatal Detection of Congenital Duodenal Obstruction—Impact on Postnatal Care
Prenatal diagnosis of congenital duodenal obstruction is only achievable in cases of complete congenital duodenal obstruction by sonographic detection of the pathognomonic double bubble sign. Patients with incomplete duodenal obstruction showed no sign of duodenal obstruction on prenatal scans and thus were diagnosed and treated later
Epidemiology and One-Year Follow-Up of Neonates with CDH-Data from Health Insurance Claims in Germany
Congenital diaphragmatic hernia (CDH) is a major congenital malformation with high mortality. Outcome data on larger unselected patient groups in Germany are unavailable as there is no registry for CDH. Therefore, routine data from the largest German health insurance fund were analyzed for the years 2009-2013. Main outcome measures were incidence, survival and length of hospital stay. Follow-up was 12 months. 285 patients were included. The incid…
Influence of vocal effort on average and variability of fundamental frequency
Read and spontaneous speech was produced by 100 male adult speakers of German in a neutral setting and in a Lombard setting, where 80 dB noise was presented over headphones. Average f0 (‘f0mean’) and relative standard deviation of f0 (‘f0varco’) were determined for each speaker in each of the four conditions spontaneous neutral, spontaneous loud, read neutral and read loud. The results confirm that when increasing vocal effort from neutral to lou…
A new tool for the visualization of magnetic features on audiotapes
The visualization of magnetic features can be of forensic relevance in the field of tape authentication. The Research Institute for Material Science and Technology in Zelenograd, Russia, has developed crystals with magneto-optical properties which permit convenient, precise and non-destructive visualization of magnetic information. These crystals change their optical properties according to external magnetic fields. The magneto-optical effects ma…
Forensic study of a case involving SMS text-to-speech conversion
The process of decoding the content of a message involving Short Message-to-speech conversion is described in the form of a forensic case study. The intelligibility of the message was low, primarily due to the fact that the written input to the text-to-speech system was inTurkish although the system was designed for text-to-speech conversion in German. This created some form of synthesised Turkish with a German “accent”. It is shown how “spectrog…
