Disseminated coxsackievirus B fulminant myocarditis in an immunocompetent adult: A case report: Case of disseminated coxsackievirus myocarditis

Coxsackieviral myocarditis is associated with systemic involvement in neonates; however, fulminant coxsackieviral myocarditis is rare in adults, and its dissemination with fatal myocarditis involving kidneys, liver, and adrenal is further rarely reported. We report a case of fulminant myocarditis along with dissemination of coxsackievirus, which was clinically unrecognized.     

Fine-needle aspiration biopsy with a vacuum test tube

A simple, low-cost, automatic aspiration system that makes use of vacuum test tubes designed for the drawing of venous blood has been used for real-time ultrasound (US)-guided fine-needle aspiration biopsy of 13 cysts (breast), an abscess (liver), and five solid (breast, liver, thyroid) masses. Because it allows the operator to perform aspiration with one hand while holding the real-time US transducer with the other, and because creation of the suction is associated with no significant displacement of the needle, this approach has allowed sampling of lesions less than 1 cm in diameter. No complications have occurred.     

Intraluminal calcifications in the small bowel of newborn infants with total colonic aganglionosis

Intraluminal calcifications were found in the small bowel of 4 newborns with total colonic aganglionosis. Abdominal radiography demonstrated circular aggregations of small punctate calcific densities in the right lower quadrant and evidence of bowel obstruction. There was a microcolon in each case. The calcifications, which resemble those seen in small intestinal atresia and stenosis, are probably related to fetal intestinal stasis, and may be differentiated from those due to meconium peritonitis.     

Ultrasound examination of the hand

Twenty-five surgically confirmed soft-tissue lesions of the hand were examined prospectively by real-time ultrasound. Use of sonography enabled a reliable diagnosis of the cystic or solid nature of soft-tissue lesions, an accurate estimation of the volume, and precise three-dimensional localization of the abnormality. Sonography also facilitated the location of foreign bodies. Assessment of anatomic relationships of these lesions to tendons and surrounding structures by real-time sonography during palpation, flexion, and/or extension also aided in the surgical approach.     

Magnetic resonance imaging of the brainstem: normal structure and basic functional anatomy

Normal structure and basic functional anatomy of the brainstem were studied using anatomic sections obtained with a cryomicrotome whole-organ sectioning technique. Major tracts and nuclei were identified and their function summarized. Magnetic resonance imaging of the brainstem was performed on 10 normal volunteers. By comparing these images with the corresponding anatomic sections, normal structures, including major tracts and nuclei, were identified. Knowledge of location and function of clinically important brainstem nuclei and tracts is necessary for optimal magnetic resonance image interpretation.
