Comparative Study
Lack of efficacy of antibiotic-impregnated shunt systems in preventing shunt infections in children.
Shunt infection is a common and serious complication of cerebrospinal fluid (CSF) shunting most commonly caused by skin flora contamination at surgery. Recent studies indicate that the use of antibiotic-impregnated (AI) shunt systems may reduce the risk of postoperative shunt infections. We evaluated the incidence of shunt infections associated with the use of AI shunt catheters and compared it with the incidence associated with standard non-AI catheters. ⋯ We reviewed 160 shunt procedures (80 per group). The infection rate was 5.0% among patients with AI catheters compared with 8.8% in the control group (P = 0.534, Fischer's exact). The average time to infection was similar between the two groups. Among the AI group, the shunt infection rate did not differ between ventricular catheter, distal catheter revisions, and revisions of ventricular and peritoneal tubing. In contrast with other reports, we found no significant reduction in the pediatric CSF shunt infection rate with the use of AI shunt systems. Any recommendation for or against the routine use of AI systems in children requires a prospective, blinded, randomized-controlled trial with adequate power.

The bones of the skull of the newborn and nursing infants, in general, possess great malleability. For this reason, the depressed fractures occurring at this age are called "Ping Pong" or "Green Stick" fractures. The treatment of these fractures is surgical according to different authors, although some of these fractures that happen in childbirth can elevate themselves spontaneously. ⋯ Finally, it has been demonstrated that this procedure is simple, inexpensive, and avoids surgical intervention.

The aim of this study is to retrospectively evaluate a series of consecutive patients affected by post-hemorrhagic hydrocephalus in prematurity, treated with an implant of an Ommaya reservoir followed by ventriculo-peritoneal (VP) shunt and/or endoscopic third ventriculostomy (ETV) to evaluate the safety and efficacy of these treatment options in the management of the condition. ⋯ The combination of Ommaya reservoir, VP shunt, and the aggressive use of ETV as a primary treatment or as an alternative to shunt revision allowed for a significant reduction of shunt dependency in a traditionally shunt-dependent population. Further studies are warranted to optimise the algorithm of treatment in these patients.

The management of intra- and paraventricular lesions is one of the fields in which modern neuroendoscopic techniques have given the most significant contribution in terms of reduction in operative invasiveness and postoperative complications. In this context, fluid cysts represent an ideal ground on which results obtained with traditional surgical procedures (open surgery, shunting) have more and more to compare with the increasing number of encouraging results obtained by neuroendoscopy. ⋯ Our results confirm that endoscopic management of intra- and paraventricular cysts is a valid alternative to open surgery as well as to shunting procedures. Control of clinical symptoms and signs was obtained in around 80% of our patients, while radiological evidence of cyst size reduction occurred in more than 95% of them. These rates are comparable with results of open surgery and shunting. The main advantage of neuroendoscopy is the low incidence of complications, a result that is confirmed by the present series.

Biography Historical Article
Holoprosencephaly in Mexico: first reported autopsy case by Dr. Agustín Arellano.
Holoprosencephaly with cyclocephaly is an early disturbance of organogenesis and has been classified as a severe brain malformation starting in 1755 by Eller in Germany, then in 1822 by Etienne Geoffroy de Saint-Hilaire in France, and finally in 1828 by Tiedemann in Germany. In 1839, Dr. Arellano published in Mexico a necropsy case of holoprosencephaly. This was the fourth publication worldwide on this kind of pathological alteration. Furthermore, in reference to diaphragmatic herniation, Arellano's paper is the fourth world report, having appeared 9 years before Bochdalek's publication. We have not found any other report that appeared before 1839 in the Americas on this particular malformation, and we consider that Arellano's paper was the first of its kind on the American continent. ⋯ As is well known, the publications of this Mexican medical researcher were, for his time, at the level of those of the most developed countries. It is also important to know that the medical journal where Arellano's work was published, the "Periódico de la Academia de Medicina de Mégico(sic)," founded and directed by Dr. Manuel Carpio in 1836, is the direct forerunner of the present Gaceta Médica de México, the oldest currently published journal in the Americas.
