Vagus Nerve Stimulation (VNS) is Effective in Treating Catastrophic 1 Epilepsy in Very Young Children
No full textThe objective of this study is to evaluate the safety and efficacy of vagus nerve stimulation (VNS) in very young children suffering from catastrophic epilepsy and status epilepticus. We reviewed files of 60 VNS-implanted children at our institution and we selected six very young patients, less than 3 years old (mean age at implant 1.6 years). All patients suffered from severe cognitive impairment and catastrophic epilepsy with underlying diagnosis of hemimegalencephaly (1), hypoxic-ischemic encephalopathy (1), tuberous sclerosis complex (1), and malignant migrating partial epilepsy of infancy (3). Three patients were VNS-implanted during admission at intensive care unit (ICU) after developing life-threatening status epilepticus. The mean follow-up time was 41.6 months. The VNS was implanted using a single cervical incision. No surgery-related complications were observed. Four of six children have shown a significant, persistent improvement in seizure control (range, 60-90%). In patients with status, insertion of the vagal nerve stimulator allowed early cessation of status and discharge from ICU. Quality of life and parental satisfaction improved and for three children there was some milestone evolution. Catastrophic epilepsy in infancy can be devastating and difficult to treat with drugs and surgery. If resective surgery is inappropriate or refused, VNS can be considered as a well-tolerated and effective procedure even in toddlers affected by severe epilepsy and multiple developmental disabilities
Intrathecal chemotherapy for treatment of overt meningeal leukemia: comparison between intraventricular and traditional intralumbar route.
No full textDespite advances in the treatment of acute lymphoblastic leukemia (ALL), overt meningeal leukemia remains a dire condition. The role of intraventricular chemotherapy (IVC) in its treatment is still a matter for debate. Data suggesting benefit from it have been countered by statements of concern regarding the potential complications associated with its use. This report details our results from using IVC.We compared two groups of adult patients with ALL at their first meningeal involvement. Twelve of them were submitted to ILC and 9 to IVC.Our data showed that IVC yielded a higher rate of complete response (88\% vs. 33\%) and a lower incidence of second CNS relapse than did ILC (none vs. 50\%). Even though there were more long-term disease-free survivors (33\% vs. 8\%) among the IVC patients, the difference in median event-free survival was not significant (120 vs. 80 weeks; p = 0.66). IVC was associated with a longer overall survival (p = 0.005) and CNS remission time (p = 0.046). Two cases refractory to ILC were later fully responsive to IVC. There were 22\% device-related and 11\% drug-related complications.The results are promising, but the small series does not allow for any definite conclusion. In our opinion, the hazards inherent in the placement and operation of the device do not outweight the benefits of IVC for the treatment of overt meningeal leukemia and should not preclude its use. Accurate neurosurgical technique, meticulous care in drug administration and experience with this form of therapy can all contribute to minimizing complications so that full advantage can be taken of IVC's potential
BOBBLE HEAD DOLL SYNDROME IN A CHILD WITH A CYST OF THE THIRD VENTRICLE AND HYDROCEPHALUS

Bobble head doll syndrome in a child with a third ventricular cyst and hydrocephalus
No full textIntroduction: The bobble head doll syndrome, mainly affecting children under 10 years of age, is a rare and surgically treatable movement disorder characterized by head bobbing occurring at a rate of 2-3 times/ s. Its pathophysiological mechanism is not well known but two main factors are commonly associated with the condition: a dilatation of the third ventricle and, more frequently, a cystic lesion rather than a solid mass in the region of the third ventricle. Illustrative case: The illustrative case concerns a child with a third ventricular cystic lesion and hydrocephalus who had experienced abnormal head movements since the age of 1 year as well as ataxia and tremor of the arms. Contrast cranial MRI, at the age of 3, demonstrated enlargement of the third and lateral ventricles, a ballooned cyst inside the third ventricle with compression of all the diencephalic structures, a funnel dilation of the cranial part of the aqueduct, and a cyst in the septum pellucidum. A ventriculoperitoneal shunt (Hakim-Cordis) was placed and the head bobbing, tremor of the arms, and ataxia disappeared immediately. Conclusion: The good and immediate clinical result in our case emphasizes the opinion that the reduction of CSF pressure is the best therapeutical option in the bobble head doll syndrom
Anterior cervical epidural abscess treated by endoscopy-assisted minimally invasive microsurgery via posterior approach.
No full textThis is a report of clinical manifestation, physical findings, neurophysiological data, magnetic resonance imaging, and results after surgery in a 71-years-old man with cervical abscess. Magnetic resonance imaging after two weeks of empiric antibiotic therapy demonstrated the persistence of an anterior cervical epidural collection and signs of spondylodiscitis at the C5-C6 and C6-C7 levels. Surgery was performed by posterior endoscopy assisted key-hole approach at the C2-C3 level to drain the abscess and to decompress the spinal cord. Postoperative specific medical treatment was then administered. A successful outcome, at 24 months follow-up, was achieved by surgery with complete clinical recovery, resolution of the abscess and healing of the spondylodiscitis. After unsuccessful blind medical therapy the minimally invasive microsurgical technique allowed us to keep the surgical injury of the healthy tissue to a minimum while producing the maximum therapeutic effect
Complications of vagal nerve stimulation for epilepsy in children
No full textVagal nerve stimulation (VNS) is a surgical option to treat drug-resistant epilepsy. A few side effects have been described, mainly as anecdotal reports. We analysed our material concerning a juvenile population to identify the most common and most important complications, discussing them with the literature. Thirty-six patients were studied (18 months-18 years old). The children were assessed before the VNS implant and 3, 6, 12, 24 and 36 months after surgery. The mean follow-up was 30 months. Four patients required a second surgery: two for changing the device 3 years after implant; one for revision of an imperfect implant; one for removing a non-functioning device. In one patient a transient vocal cord paralysis was observed. Hoarseness was the main complaint (38.8%). More infrequent was mild sleep apnoea (8.3%), sternocleidomastoid muscle spasm, drooling and snoring in one patient each. Skin scars were reported with a different frequency according to the surgical technique. At variance with the literature reports, we did not observe infections. Side effects of VNS can be minimised, but not avoided completely, with a correct technical procedure, which in turn depends upon a thorough knowledge of vagus nerve anatomy
