The findings show that artificial neural networks can predict shunt infection with a high level of accuracy in children with shunted hydrocephalus. Also, the contribution of different risk factors in the prediction of shunt infection can be determined using the trained network.
Context:Ventriculoperitoneal (VP) shunt and endoscopic third ventriculostomy (ETV) are the established surgical treatments for obstructive hydrocephalus (HCP). Powerful evidence regarding the best therapeutic approach for infants with obstructive HCP is lacked.Aims:Comparison of the therapeutic efficacy of VP shunt and ETV/choroid plexus cauterization (CPC) in infants with obstructive HCP.Settings and Design:This was a randomized, active control, unblind, single-center, clinical trial.Methods:Infants with obstructive HCP were randomly allocated to each intervention group (ETV/CPC or VP shunt). They were monitored for at least 6 months for any sign of raised intracranial pressure (rICP). The recurrence of rICP signs requiring surgical intervention was considered as intervention failure.Statistical Analysis:The association between intervention group and outcome was tested with Chi-square test, and P = 0.05 or less was considered statistically significant.Results:Of the total fifty patients entering the study, 49 were included in the final analysis, 27 of them were in VP shunt and 22 in ETV/CPC group. Seventeen patients (34%) were female and 33 (66%) were male with mean age of 3.74 ± 3.1 months (range = 10 days – 11 months). Thirty-nine (79.6%) were under 6 months of age and the remaining were 6 months or older. The overall success rate in 36-month follow-up was 88.5% and 68.2% for VP shunt and ETV/CPC, respectively, with the difference being not statistically significant.Conclusion:The current study determined no inferiority of ETV/CPC compared to VP shunt, and therefore, it may become an efficient treatment for obstructive HCP in infants.
Craniopagus is a very rare congenital anomaly that tends to affect females more often than males. It is classified as partial or total. Most affected twins are either stillborn or die during the perinatal period. Those who survive birth should undergo detailed radiological evaluations soon after their condition becomes stable so that the precise anatomy of the conjoined part can be defined and surgery can be planned in detail by a multidisciplinary team. Recommendations for decreasing the risk of unsuccessful surgery include performing surgery on an elective basis after extensive preoperative radiological evaluations as well as when the twins are at an acceptable age and weight for a complex surgical separation, generally as staged procedures. In addition, the operation should be performed by a well-equipped expert multidisciplinary team.When one of the conjoined twins dies, however, surgical separation cannot be postponed because the shared circulatory system predisposes the alive child to life-threatening complications, including coagulopathy. The authors report on the successful separation of craniopagus twins performed on an emergency basis at 32 weeks of gestational age because of the sudden death of one of them. At the time of separation surgery, the twins each weighed 1250 g. To the best of the authors’ knowledge, this is the youngest age and lowest weight yet reported for successful surgical separation. The surviving twin developed a pseudomeningocele, which required a second operation and placement of a cystoperitoneal shunt 4 months after the operation. Additional surgery is planned to repair a cranial defect that resulted from the pseudomeningocele, but his general physical and mental condition was otherwise good at latest follow-up (12 months after separation surgery).
Different conditions including hemodynamic alteration, compression of adjacent hematoma, and narrowing of related vascular structures have been described to cause thrombosis of VoGAM. The relevant literature to address possible mechanism is reviewed.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
