The Impact of Drug and Alcohol Intoxication on Glasgow Coma Scale Assessment in Patients with Traumatic Brain Injury.

BACKGROUND: The effect of intoxicating substances on assessment of Glasgow Coma Scale (GCS) in the trauma setting has not been completely elucidated. METHODS: A trauma registry was queried for patients with blunt head trauma in 2013-2017. Initial GCS score and toxicology screening from the database were reviewed. Next recorded GCS score from the neurosurgery evaluation and change in GCS score (ΔGCS) were compared. RESULTS: We reviewed 468 patients. In 217 (46.4%) patients, no toxic substances were found, whereas >1 toxic substance was found in 104 (22.2%) patients. Alcohol level above the legal limit was found in 109 (23.3%) patients, marijuana was found in 105 (22.4%) patients, benzodiazepines were found in 94 (20.1%) patients, opiates were found in 48 (10.3%) patients, and cocaine was found in 41 (8.8%) patients. Mean change in GCS score was significantly higher in impaired patients compared with patients with a negative screening test (1.74 ± 2.4 vs. 0.75 ± 2.7, P < 0.001); this is despite both groups having a similar initial GCS score (6.23 ± 3.86 in impaired group vs. 6.47 ± 3.52 in sober group, P = 0.677). Initial GCS score was 3 in 187 patients, of whom 150 had a positive toxicology screen. Change in GCS score was significantly higher in the impaired group (2.75 ± 2.7 vs. 1.19 ± 1.8, P < 0.001). CONCLUSIONS: Intoxicating substances can confound GCS assessment in trauma patients. This can have effects on patient care as well as performance metrics and predictive analytics. These patients should be screened, and intoxicating substances should be reversed or allowed to wear off before GCS score is recorded for benchmarking or quality reporting.

A 14-Year Review of Socioeconomics and Sociodemographics Relating to Intracerebral Abscess, Subdural Empyema, and Epidural Abscess in Southeastern Louisiana.

BACKGROUND: Secondary intracranial infections are a persistent health concern despite advancements in medicine and improvements in surgical care. Previous studies have reported on the incidence of infection and outcomes in the immunocompromised patient, yet few studies have investigated demographic elements linked to contracting a secondary intracranial infection, a preventable disease. OBJECTIVE: The aim of this study was to uniquely describe immunocompetent pediatric patients with secondary intracranial infections and further examine the socioeconomic and sociodemographic factors that may put them at higher risk of acquiring an infection. METHODS: A retrospective review was conducted for patients presenting with intracranial infections to the regional Children's Hospital between 2001 and 2014. Patients with a previous history of neurosurgical disease or procedure were excluded. A Z test for proportions was performed to detect significant variations between demographic groups. RESULTS: A total of 41 patients were included in the study sample. From 2001 to 2014, 63.4% of patients diagnosed with intracranial infections were white, and 36.5% were other/nonwhite. This incidence of infection varied significantly between white and nonwhite (P = .015). At Children's Hospital, 19.5% of patients were privately insured and 80.5% had public health insurance. The most notable variation of a secondary intracranial infection was health insurance; 51% of Louisiana children carry public insurance, yet they represent more than 80% of disease incidence (P < .001). CONCLUSION: Improving access to care and treatment for underinsured populations may contribute to a decrease in secondary intracranial infection cases.

Retroperitoneal, paraspinal migration of distal ventriculoperitoneal shunt catheter: a peculiar complication of cerebrospinal fluid shunt.

We describe a case of a ventriculoperitoneal shunt malfunction in which the tip of the peritoneal catheter found its way to the paraspinal subcutaneous tissues. The specific findings on physical examination and the results of the imaging made to make the diagnosis are presented. No prior report of migrating shunt tubing into this anatomic area was found in the literature. This curiosity is added to the list of organs or spaces shunts are capable of wandering into.

Pseudotumor cerebri associated with modified Fontan anatomy.

Surgical treatment of functional single-ventricle heart disease with a modified Fontan procedure results in elevated central venous pressure. The case report describes a 19-year-old boy with hypoplastic left heart syndrome and Fontan palliation that resulted in frequent debilitating headaches after transcatheter closure of systemic venous-to-pulmonary venous collaterals. Measured increased intracranial pressure and prompt relief of the headaches with lumbar puncture favored a diagnosis of pseudotumor cerebri. After implantation of a lumboperitoneal shunt, the patient's headaches improved dramatically. Headaches are frequent in patients with Fontan circulation. The current literature supports a pivotal role of elevated dural venous sinus pressure in the pathogenesis of pseudotumor cerebri. The high superior and inferior vena caval pressures characteristic of modified Fontan anatomy may account for headaches in some of these patients.

Cranial fasciitis presenting as an intracranial mass in a 10-year-old girl.

Cranial fasciitis is a mass-forming lesion of myofibroblastic proliferation of the skull and overlying soft tissue and occurs most frequently in pediatric patients. Cranial fasciitis has the same histological features as nodular fasciitis, which appears in the subcutaneous tissue in other parts of the body. Cranial fasciitis can involve the outer table of the skull, and it occasionally extends through the skull to form a mass involving both soft tissue and the epidural space. Intracranial cranial fasciitis without a soft tissue mass is extremely rare. Here, we report a case of a 10-year-old girl who presented with a massive intracranial mass that caused midline shift of the brain. The lesion showed focal areas of osseous metaplasia and a cytogenic abnormality of t(17;18)(q25∶q12.2) that have not yet been reported.

Cranial vault reduction cranioplasty in children with hydrocephalic macrocephaly.

Craniofacial surgeons are rarely presented patients with extreme hydrocephalic macrocephaly due to early diagnosis and treatment of the hydrocephalus. Macrocephaly can significantly limit or prohibit mobility, hygiene and can drastically change lifestyle and developmental issues. The authors herein report on four consecutive total cranial vault reduction cranioplasty procedures for correction of hydrocephalic macrocephaly. The patients had a reduction in cranial volume ranging from 111-641 mL. All patients survived the procedure. Improvement in head control and aesthetics were improved in all patients. All of the patients required at least one shunt revision following the procedure. We conclude that total cranial vault reshaping is safe and effective for the treatment of macrocephaly secondary to hydrocephalus.

Improved survival in central nervous system aspergillosis: a series of immunocompromised children with leukemia undergoing stereotactic resection of aspergillomas. Report of four cases.

Central nervous system (CNS) aspergillosis remains a daunting diagnosis. This opportunistic mycosis historically carries a mortality rate approaching 100% in immunocompromised patients, with death ensuing within days after the onset of neurological symptoms. From their literature review, the authors concluded that children contracting CNS aspergillosis while undergoing systemic chemotherapy for leukemias represent a particularly unfortunate prognostic group. Antifungal medications prove ineffective for treating CNS aspergillosis in patients immunocompromised because of their chemotherapy regimens. In contrast, withholding chemotherapy to reverse immunosuppression, thereby improving the efficacy of antifungal medications, allows for progression of the primary leukemic disease. The authors present a series of four immunosuppressed patients whose course of treatment for leukemia was complicated by CNS Aspergillus sp. abscesses. Multiple cerebral fungal abscesses developed in two patients and a single cerebral abscess developed in two. All four patients underwent frameless stereotactic resection of the aspergilloma. All children later experienced resolution of their CNS infections and full neurological recovery. At 2- to 4-year follow ups, one patient has died of leukemia and the other three continue to thrive without evidence of recurrent aspergillosis. Given the grave natural history cited in the literature for this disease when medical treatment is instituted alone, the authors stress the crucial role of stereotactic neurosurgery for the intelligent treatment of immunocompromised children suspected of harboring a CNS aspergilloma abscesses. The authors propose that the goal for successful treatment in these patients should be gross-total resection of the abscess, its wall, and its capsule.

Giant gram-negative brain abscesses. Report of two cases.

Giant brain abscesses have become a rarity in North American pediatric neurosurgery practice. A high index of suspicion and readily available noninvasive brain imaging have made the diagnosis of brain abscess easier and more prompt than in past decades. There are complicating factors, however, that may delay a timely diagnosis and allow the disease to progress to extremes before becoming evident. Children with hydrocephalus and ventricular shunts can harbor large abscesses. As the volume of purulent material expands, cerebrospinal fluid can be forced down the shunt system, reducing the intracranial pressure (ICP), at least for a time. Infants are typically more tolerant of an expanding mass lesion, allowing considerable time to pass before symptoms of increased ICP manifest. The authors report two cases of brain abscess, which achieved giant dimensions before the children became symptomatic. The pathogens were found to be Gram negative and of several species. The properties of these Gram-negative pathogens to create abscess and the clinical circumstances, including the presence of meningitis and ventricular shunts, which contributed to the process, are explored.
