We describe the prenatal sonographic findings in 2 cases of amniotic band sequence-related acrania. In the first case, sonography demonstrated acrania, asymmetric facial clefts, and digital fusion on the hands and feet. In the second case, sonography demonstrated acrania and amniotic bands adhering to the brain, face, and body. This report highlights the importance of a careful search for amniotic bands and a detailed survey of the fetus' face, digits, and body in the sonographic evaluation of fetal acrania.

ABSTRACT

We report on a case of duplicated hydrometrocolpos with uterus didelphys, a septate vagina, lower vaginal atresia, a persistent urogenital sinus, left ear agenesis, a single umbilical artery, and an imperforate anus, but without the associated features of McKusick–Kaufman syndrome such as polydactyly and congenital heart defects. Ultrasound‐guided fluid aspiration of the fetal intrapelvic cystic mass helped to decompress the distended genital organs, decrease the severity of the urinary tract obstruction, delineate the ultrasonographic image of duplicated hydrometrocolpos to differentiate it from other intrapelvic cystic masses, and obtain fluid for cytological analysis.

Spontaneous and complete regression of malignant neoplasms is extremely unusual. To our knowledge, this case report is the first description of spontaneous regression of an extranodal malignant lymphoma occurring in the conjunctiva and orbit. A 40-year-old woman noticed a pink conjunctival mass at the medial aspect of her left eye that had been present for 3 weeks. She presented on May 5, 2003. Ophthalmologic examination showed a salmon-colored mass along the lateral side of the caruncle. CT revealed a mass in the medial orbit. Surgical biopsy exhibited a malignant lymphoma, diffuse large B-cell type. After biopsy, the tumor spontaneously decreased in size and completely disappeared in 5 weeks. At 6 months' follow-up, the tumor had not recurred.

A micellar electrokinetic capillary method for the simultaneous determination of the sweeteners dulcin, aspartame, saccharin, and acesulfame-K and the preservatives sorbic acid; benzoic acid; sodium dehydroacetate; and methyl-, ethyl-, propyl-, isopropyl-, butyl-, and isobutyl-p-hydroxybenzoate in preserved fruits is developed. These additives are ion-paired and extracted using sonication followed by solid-phase extraction from the sample. Separation is achieved using a 57-cm fused-silica capillary with a buffer comprised of 0.05 M sodium deoxycholate, 0.02 M borate-phosphate buffer (pH 8.6), and 5% acetonitrile, and the wavelength for detection is 214 nm. The average recovery rate for all sweeteners and preservatives is approximately 90% with good reproducibility, and the detection limits range from 10 to 25 microg/g. Fifty preserved fruit samples are analyzed for the content of sweeteners and preservatives. The sweeteners found in 28 samples was aspartame (0.17-11.59 g/kg) or saccharin (0.09-5.64 g/kg). Benzoic acid (0.02-1.72 g/kg) and sorbic acid (0.27-1.15 g/kg) were found as preservatives in 29 samples.
