Decadron, Diamox, and Zantac: A Novel Combination for Ventricular Shunt Failure in Pediatric Neurosurgical Patients.

OBJECTIVE: Cerebral ventricular shunt failure is common and presents with symptoms that range from headaches to death. The combination of Diamox (acetazolamide), Decadron (dexamethasone), and Zantac (ranitidine) (DDZ) is used at our institution to medically stabilize pediatric patients presenting with symptomatic shunt failure before shunt revision. We describe our experience of this drug combination as a temporizing measure to decrease symptoms associated with shunt failure. METHODS: We performed a single-center retrospective chart review of patients younger than 18 years with ventricular shunt failure who underwent a shunt revision between January 2015 to October 2017 and received DDZ before surgery. The outcome variables evaluated included pre-DDZ and post-DDZ clinical symptoms, pain scores, and vital signs. RESULTS: There were 112 cases that received DDZ before shunt revision. The 4 most commonly reported symptoms were analyzed. Headache was observed in 42 cases pre-DDZ, and post-DDZ there was a 71% reduction in headache (P < 0.0001); emesis was reported pre-DDZ in 76 cases, and post-DDZ there was an 83% reduction (P < 0.0001); irritability was noted pre-DDZ in 30 cases, and post-DDZ there was a 77% reduction (P = 0.0003); lethargy pre-DDZ was observed in 60 cases, and post-DDZ 73% demonstrated improvement (P < 0.0001). Maximum pain scores significantly decreased post-DDZ (P < 0.0001). Heart rate, systolic, and diastolic blood pressures significantly decreased post-DDZ (P < 0.0001, P < 0.0001, P = 0.0002, respectively). CONCLUSIONS: The combination of Decadron, Diamox, and Zantac is a novel treatment for ventricular shunt failure that may temporarily improve symptoms in patients awaiting shunt revision. Future studies could compare efficacy with other medical treatments.

Case Series of Rapid Surgical Interventions in Fulminant Intracranial Hypertension.

AIMS: Examine ophthalmologic outcomes and complications of lumbar drain and cerebrospinal fluid shunts in pediatric fulminant intracranial hypertension. METHODS: Patients under 21 years of age with a diagnosis of fulminant intracranial hypertension with temporary lumbar drain only, shunt after lumbar drain, and shunt only were included. Parameters investigated include lumbar drain data, medication freedom, time to resolution of papilledema, improvement in cranial nerve palsy, afferent pupillary defects, visual fields, visual acuity, and complications of each intervention. RESULTS: Four patients had temporary lumbar drain, 2 temporary lumbar drain and cerebrospinal fluid shunt, and 3 shunt only. All achieved medication freedom and resolution of papilledema and cranial nerve palsies (if present). Most had resolution of preprocedure afferent pupillary defects. Minor residual visual field deficits occurred in 67%, and all had visual acuity improvement. One patient's lumbar drain dislodged, and one patient had 2 cerebrospinal fluid shunt revisions. CONCLUSION: Temporary lumbar drain with medical therapy may be a viable first approach to fulminant intracranial hypertension.

Liposclerosing Myxofibrous Tumor of the Cranial Vault: A Case Report.

BACKGROUND AND IMPORTANCE: Liposclerosing myxofibrous tumors (LSMFTs) are rare benign fibro-osseous tumors most frequently occurring in the proximal femur. We report the first case of this rare tumor occurring within the calvarium. CLINICAL PRESENTATION: Our patient presented with a 2-yr history of enlarging, painless, fixed mass over the left forehead. She underwent surgical resection and the mass was histologically confirmed to be a LSMFT. CONCLUSION: LSMFT is a rare tumor that should remain on the differential for lesions of the calvarium. When diagnosed, this lesion can be removed with the goal of gross total resection and excellent cosmesis can be achieved.
