Hypoperfusion complex is an uncommon entity found on computed tomography (CT) of blunt trauma. It is more common in children compared to adults. Everyone should be aware of this entity to interact with clinicians to aid in triage and management of patients in view of poor prognosis. It is also important to prevent unnecessary laparotomies by confusing abdominal organ injuries. There are certain visceral and vascular findings described on abdominal CT that would alert the radiologist for this entity. This pictorial review should increase radiologists' awareness and recognition of the CT manifestations of hypoperfusion complex before an irreversible state of shock occurs in blunt abdominal trauma. 相似文献

Vascular lesions of the scrotum are uncommon; the most common among them are varicocele lesions. The other vascular lesions that may involve the scrotum are hemangioma, lymphangioma, and arteriovenous malformations, which are exceedingly rare. The imaging modalities useful in the diagnosis and management of scrotal vascular lesions are grayscale sonography, color Doppler sonography, magnetic resonance imaging, magnetic resonance angiography, and digital subtraction angiography. We present two cases of scrotal vascular lesions involving the extratesticular scrotal soft tissues. Patients presented with bleeding and were treated by radiological interventional technique. We emphasize the importance of superselective catheterization and distal embolization. 相似文献

An abnormality of chromosome 16 in an eight year-old male was associated with a multiple congenital anomalies syndrome characterized by myopathy, cataracts, blepharophimosis, microcephaly, failure to grow, profound mental retardation, moderate sensorineural hearing loss, grand mal seizures, bilateral inguinal hernia, and thoracolumbar kyphoscoliosis. Magnetic resonance imaging of the head demonstrated absence of the corpus callosum and extensive loss of brain parenchyma in the occipital regions. Chromosome analysis from peripheral blood of the patient showed a rccombinant chromosome 16 [46, XY, rec (16), dup (p13.1 → p13.3) del (q22 → q24)]. The mother had a pericentric inversion of chromosome 16 [46, XX, inv(16) (p13.1;q22)]. Independent recombinant DNA studies have shown that the breakpoints of these chromosomal rearrangements flank the α-globin gene cluster locus. 相似文献

An efficient method has been developed for screening solid dispersion formulations that are intended to enhance the dissolution of poorly soluble compounds. The method is based on miniaturization and automation of sample preparation by solvent casting, and dissolution testing, in a 96-well plate format, using less than 0.1mg of compound per well. To illustrate the method, six polymers and eight surfactants were screened, individually and in combination, for their ability to dissolve a compound with aqueous solubility of < 1 microg/ml in simulated intestinal fluid. Screening was performed at an excipient/compound ratio of 10:1, and a polymer/surfactant ratio of 3:1 for ternary formulations. Sixteen of the 48 ternary formulations dissolved the compound to a level > 100 microg/ml, i.e. at least a 100-fold increase over the aqueous solubility. A number of synergies were observed wherein the performance of a ternary formulation greatly exceeded that of either of the corresponding binary formulations. Thirteen 'hits' from screening were scaled up with melt methods, and approximately 2/3 of these showed comparable dissolution enhancement when tested at larger scale. Five of these were administered to rats, and the absolute oral bioavailability ranged from 10 to 23%, versus less than 1% for the unformulated compound. 相似文献
