Severe Clostridial Pyomyoma following an Abortion Does Not Always Require Surgical Intervention

Background. Clostridial infection following pregnancy may be fatal, and surgery is considered as the treatment of choice. We suggest a conservative management in selected cases when preservation of fertility is of major importance. Case. A 41-year-old primigravida presented with abdominal pain and fever, one day following dilatation and curettage at 20 weeks of gestation. Her abdomen was diffusely tender, with a uterus enlarged to 20 weeks' gestation. Laboratory studies were consistent with sepsis and hemolysis. CT demonstrated a gas-containing mass compressing the uterine cavity, and presence of air in pelvic veins. Blood cultures were positive for Clostridium perfringens. The patient was treated conservatively, with IV antibiotics and fluid resuscitation, and recovered. Conclusion. In selected cases of infected myoma complicated by clostridial sepsis, refraining from surgical intervention is a possible therapeutic approach

Simultaneous multifocal intracranial haemorrhages associated with staphylococcus aureus endocarditis: a plausible role for diclofenac administration

Introduction: Intracranial haemorrhage may complicate infective endocarditis, caused by ruptured mycotic aneurysms or haemorrhagic transformation of brain septic emboli. The risk of intracranial bleeding may increase with the use of non-steroidal anti-inflammatory agent (NSAIDs). Case description: We report on a 53-year-old male patient with a past history of intravenous drug abuse, who was treated with diclofenac (75 mg IM) for a few hours of preceding fever and arthralgia. Seven hours later he was hospitalised with impaired consciousness and hemiparesis. Evaluation revealed multiple intracranial haemorrhages, at least one originating from a mycotic aneurysm. Repeated blood cultures grew methicillin-resistant Staphylococcus aureus (MRSA), and echocardiography revealed a vegetation on the mitral valve, establishing the diagnosis of bacterial endocarditis. Conclusion: The abrupt simultaneous multifocal intracranial bleeds shortly following the administration of NSAIDs for a few hours of febrile disease, one clearly originating from a mycotic aneurism, are exceptional. This raises a possibility of a role for diclofenac the intracranial bleeding diathesis in this unique clinical presentation. Intracranial haemorrhage in the set-up of undiagnosed infective endocarditis (IE) might be added to the long list of potential adverse outcomes of NSAID administration, and the possibility of IE should be considered before their administration for febrile disease of undetermined cause

Semiquantitative and quantitative analyses of dynamic contrast-enhanced magnetic resonance imaging of thyroid nodules

© 2015 Wolters Kluwer Health, Inc. All rights reserved. Objective: This study was aimed to determine the utility of quantitative dynamic contrast-enhanced magnetic resonance imaging (MRI) in differentiating benign and malignant lesions in patients with known thyroid gland lesions scheduled for resection. Methods: Patients scheduled for resection of a thyroid mass were prospectively enrolled. Dynamic contrast-enhanced MRI scans of the neck were performed before surgery. After resection, patients were divided into benign and malignant groups. Quantitative and semiquantitative MRI kinetic measurements of benign and malignant lesions were compared and analyzed. Results: Twelve benign and 9 malignant lesions were identified in 19 patients. Mean Ktrans, Ve, and Kep for benign lesions were 1.69 ± 1.59 min-1, 0.44 ± 0.21 min-1, and 4.51 ± 2.96 min-1, respectively; for the malignant lesions, 0.96 ± 0.57 min-1, 0.45 ± 0.19 min-1, and 3.57 ± 3.53 min-1, respectively (P = 0.1886, 0.8036, and 0.3028, respectively). Tpeak, ERmax, slopemax, and iAUGC60 for benign lesions were 7.00 ± 8.09 seconds, 293.27 ± 141.25 seconds, 76.45 ± 65.80 seconds, and 63.46 ± 46.84, respectively; for malignant lesions, 8.11 ± 8.55 seconds, 227.6 ± 113.37 seconds, 81.17 ± 109.71 seconds, and 43.69 ± 26.19, respectively (P = 0.7525, 0.4941, 0.4474, and 0.3028, respectively). Conclusions: Dynamic contrast-enhanced MRI pattern of kinetics was not significantly different for benign and malignant lesions of the thyroid using quantitative or semiquantitative methods

Mature cystic teratoma of the posterior fossa – A case report to enrich our data on the subject

Posterior fossa cystic lesions display a diagnostic challenge as the apparent simplistic image portrays a vast array of pathological entities. We hereby present the case of mature cystic teratoma of the posterior fossa with atypical radiological appearance, in a previously healthy 6-month old male, presenting with increased head circumferences, non-communicating hydrocephalus. The lesion underwent en bloc resection, and the infant was discharged home a week later with no neurological deficits. Follow-up MRI did not demonstrate any evidence of recurrence or residual tumor

Non-invasive assessment of normal and impaired iron homeostasis in the brain

Abstract Strict iron regulation is essential for normal brain function. The iron homeostasis, determined by the milieu of available iron compounds, is impaired in aging, neurodegenerative diseases and cancer. However, non-invasive assessment of different molecular iron environments implicating brain tissue’s iron homeostasis remains a challenge. We present a magnetic resonance imaging (MRI) technology sensitive to the iron homeostasis of the living brain (the r1-r2 * relaxivity). In vitro, our MRI approach reveals the distinct paramagnetic properties of ferritin, transferrin and ferrous iron ions. In the in vivo human brain, we validate our approach against ex vivo iron compounds quantification and gene expression. Our approach varies with the iron mobilization capacity across brain regions and in aging. It reveals brain tumors’ iron homeostasis, and enhances the distinction between tumor tissue and non-pathological tissue without contrast agents. Therefore, our approach may allow for non-invasive research and diagnosis of iron homeostasis in living human brains
