    Consensus statement on abusive head trauma in infants and young children

    Abusive head trauma (AHT) is the leading cause of fatal head injuries in children younger than 2 years. A multidisciplinary team bases this diagnosis on history, physical examination, imaging and laboratory findings. Because the etiology of the injury is multifactorial (shaking, shaking and impact, impact, etc.) the current best and inclusive term is AHT. There is no controversy concerning the medical validity of the existence of AHT, with multiple components including subdural hematoma, intracranial and spinal changes, complex retinal hemorrhages, and rib and other fractures that are inconsistent with the provided mechanism of trauma. The workup must exclude medical diseases that can mimic AHT. However, the courtroom has become a forum for speculative theories that cannot be reconciled with generally accepted medical literature. There is no reliable medical evidence that the following processes are causative in the constellation of injuries of AHT: cerebral sinovenous thrombosis, hypoxic-ischemic injury, lumbar puncture or dysphagic choking/vomiting. There is no substantiation, at a time remote from birth, that an asymptomatic birth-related subdural hemorrhage can result in rebleeding and sudden collapse. Further, a diagnosis of AHT is a medical conclusion, not a legal determination of the intent of the perpetrator or a diagnosis of murder. We hope that this consensus document reduces confusion by recommending to judges and jurors the tools necessary to distinguish genuine evidence-based opinions of the relevant medical community from legal arguments or etiological speculations that are unwarranted by the clinical findings, medical evidence and evidence-based literature

    Diffusion-weighted imaging using readout-segmented EPI reveals bony metastases from neuroblastoma

    Identifying neuroblastoma (NBL) metastases is crucial to treatment and prognosis. Metaiodobenzylguanidine and Tc99M bone scans are standard for identifying bony metastases but can underestimate disease. Diffusion-weighted imaging (DWI) of the spine has shown promise in evaluating bony metastases but has been limited by artifacts. Readout-segmented echo planar imaging is a technique for DWI that minimizes artifacts allowing for improved identification of spinal disease. This report illustrates the utility of DWI of the spine using readout-segmented echo planar imaging in the detection of bony NBL metastases in a child, lending support that DWI should be included in magnetic resonance imaging scans for NBL

    Genome Sequence of Streptomyces sp. Strain Tü6071▿

    No full text
    Streptomyces sp. Tü6071 is a soil-dwelling bacterium which has a highly active isoprenoid biosynthesis. Isoprenoids are important precursors for biopharmaceutical molecules such as antibiotics or anticancer agents, e.g., landomycin. Streptomyces sp. Tü6071 produces the industrially important terpene glycosides phenalinolactones, which have antibacterial activity against several Gram-positive bacteria. The availability of the genome sequence of Streptomyces sp. Tü6071 allows for understanding the biosynthesis of these pharmaceutical molecules and will facilitate rational genome modification to improve industrial use
