A müllerian prostatic cyst protruding into the base of the urinary bladder.

The unique appearance of a midline prostatic cyst is reported. The cyst presented as a round-shaped filling defect at the base of the urinary bladder during an intravenous pyelography study. Transabdominal sonography showed the mass to be a midline prostatic cyst. The sonographic features of the mass and its location are the hallmark of a müllerian duct prostatic cyst. Midline prostatic cysts are discussed and the features differentiating müllerian duct cysts from utricle cysts are emphasized.

[Trichobezoars].

Trichobezoars are accumulations of hair casts in the stomach associated with trichophagia. The typical patient is an adolescent female who presents with alopecia and an upper abdominal mass which on moving can cause intermittent gastric outlet obstruction. Only a minority of patients have severe psychiatric disorders. When hair strands extend from the main mass in the stomach, all along the small bowel and reaching the cecum, the condition is termed the Rapunzel syndrome. In about 5% of patients there are separate hair masses in the stomach. The clinical presentation includes abdominal pain, loss of appetite, weight-loss, vomiting, loose stools, pancreatitis, jaundice, anemia and hypoalbuminemia. These signs and symptoms raise the suspicion of malignancy. Complications of bezoars include ulcers, perforation of the bowel, obstruction and intussusception. Diagnosis can be established either by barium swallow or by CT scan. Ultrasound might suggest the diagnosis, but sonographic features are definitely not pathognomonic. Treatment is surgical, as endoscopic removal is usually unsuccessful. We present 2 children in whom trichobezoars were found.

Isocratic non-aqueous reversed-phase high-performance liquid chromatographic separation of capsanthin and capsorubin in red peppers (Capsicum annuum L.), paprika and oleoresin.

A simple, rapid high-performance liquid chromatography method has been devised in order to separate and quantify the xanthophylls capsorubin and capasanthin present in red pepper (Capsicum annuum L.) fruits and preparations made from them (paprika and oleoresin). A reversed-phase isocratic non-aqueous system allows the separation of xanthophylls within a few minutes, with detection at 450 nm, using methyl red as internal standard to locate the various carotenoids and xanthophylls found in plant extracts. The selection of extraction solvents, mild saponification conditions, and chromatographic features is evaluated and discussed. The method is proposed for rapid screening of large plant populations, plant selection, as well as for paprika products and oleoresin, and also for nutrition and quality control studies.

Gallbladder pseudopolyp formation following percutaneous liver biopsy.

Following an unsuccessful liver biopsy in a 16-year-old girl in which only bile was obtained, a sonographic (US) study was performed. The findings were those of free fluid just adjacent to the gallbladder as well as a small intraluminal protrusion of the gallbladder wall. The US features of the gallbladder finding were consistent with a polyp. Gallbladder polyps are very rare in children, however, sporadic case reports do exist. An US study 24 h after the invasive procedure revealed complete regression of the free fluid; the gallbladder wall protrusion has disappeared. We suggest that the tip of the biopsy needle had penetrated the gallbladder wall and caused a bile leak. The needle penetration caused elevation of the inner wall layer at the entrance site, which was indistinguishable from the sonographic findings of a gallbladder polyp [1-4]

Gallbladder polyps in children: a rare condition.

Although gallbladder polyps are well documented in adults, only three cases in children have been reported in the literature. We present two pediatric cases in which gallbladder polyps were detected by ultrasound, confirming this as the imaging method of choice in diagnosing gallbladder disease.
