    Notes: Abstract. Neonatal hemochromatosis is a rare congenital disorder which affects both fetuses and newborns. It is characterized by hepatocellular failure, often appearing on the first day of life in the form of coagulopathy, hypoalbuminemia, hypoglycemia, and jaundice. Most of the affected infants die early in life, and definitive diagnosis has often been made only by post-mortem evaluation. With the help of MRI, plus increasing awareness of the disorder, diagnosis is now often made early, even in utero. Duplex Doppler sonography does not provide information on siderosis but shows abnormalities in the liver or blood-flow patterns associated with liver disease.

    Notes: Abstract. The aim of this article is to report on six pediatric cases of testicular microlithiasis (TM) and to review literature reports, in order to schedule US and/or other control examinations, particularly when concomitant focal or diffuse alterations of the testicular parenchymal structure are present, considering the possible association of TM with testicular tumors. Six patients (age range 4–12 years) underwent US examination for scrotal trauma (two cases) unilateral cryptorchidism (one case) follow-up after orchidopexy for bilateral cryptorchidism (one case), and varicocele (two cases). Five examinations were performed with high-frequency probes (10/13 MHz) and seven with 5/7.5-MHz frequency transducers. Follow-up US examinations were performed at different times depending on initial clinical indications, presence of underlying disease, and initial US findings. Two of the six patients underwent three US examinations, two patients underwent two US examinations, and the remaining two patients underwent only one US examination. The patients underwent a total of 12 US examinations. Microliths were bilateral in four patients and unilateral in two patients. In these two latter cases, the contralateral testis was, in one case, cryptorchid and could not be evaluated by US; in the other case it was small and hyperechogenic with orchidopexy sequelae. In three cases microliths were distributed throughout the testis. In the remaining three cases they were present in limited areas of parenchyma. As to the importance of microliths, it was defined as mild in three cases and moderate/severe in three cases. Intratubular testicular microlithiasis is a well-proved histological finding (biopsy or autopsy). More recent is the US demonstration of TM with consequent definition of its pattern: usually bilateral hyperechogenic multiple small foci without acoustic shadows with complete or partial extension to the parenchyma. Testicular microlithiasis is a rare finding. Moreover, the pediatric cases reported in the literature are very few. However, the use of high-frequency US transducers (10–13 MHz) has recently allowed an easier demonstration of this disease also in children. Of particular interest is the study of the still-debated association of microliths with other diseases such as neoplasms. Some aspects need further investigation, namely the real incidence of microliths in the healthy population, the incidence of tumors in patients with microliths, the differences between adults and children, and the different types of follow-up at different ages. In pediatric age, if TM represents an isolated sign, patients need non-invasive US follow-up until adult age. Only if TM is in association with focal lesions of testis parenchyma is it mandatory to perform biopsy or surgical treatment.

    Notes: The pharmacokinetic properties of cephalexin were studied in sea bream (mean weight 77 g), Sparus aurata (L.) after a single intraperitoneal injection (200 mg kg−1). Pharmacokinetic analysis of the serum concentrations vs time points obtained was performed using non-compartmental analysis and a compartmental pharmacokinetic model approach. In the latter case, a two-compartment open model with a lag time gave the best fitting. The maximum peak serum concentration was 5.018 mg ml−1 kg−1 1 h post-treatment. The area under the curve (AUC) cephalexin was 17.394 mg·h kg−1 and the elimination half-life of 1.83 h.

    Notes: Summary A male newborn with prenatal cytomegalovirus infection was referred for cranial ultrasound. The cranial ultrasound demonstrated areas of increased echogenicity in the thalamic and gray nuclei resembling “a branched candlestick”. Doppler technique located the “branched candlestick” along the thalamostriate arteries. This image is particularly interesting because to our knowledge it has never before been described in congenital cytomegalovirus infection, but only in congenital rubella.

    Notes: Abstract Isolated oesophageal leiomyomatosis in children is very rare. The association between leiomyomatosis of oesophagus and female genital tract and an Alport like hematuric nephritis has been recognized as a distinct entity by Garcia-Torres and Guarner [1]. Since then few other cases of this syndrome have been observed. Congenital cataracts and neurosensory deafness have been added to the clinical spectrum. Autosomal dominant inheritance is suggested by the familial cases. We report a patient who presents, as a new finding, leiomyomatosis of the rectum.
