Abstract BACKGROUND CSF shunting is among the most widely utilized interventions in patients with idiopathic intracranial hypertension (IIH). Ventriculoperitoneal shunting (VPS) and lumboperitoneal shunting (LPS) are 2 possible treatment modalities. OBJECTIVE To evaluate and compare complications, malfunction, infection, and revision rates associated with VPS compared to LPS. METHODS Electronic medical records were reviewed to identify baseline and treatment characteristics for patients diagnosed with IIH treated with VPS or LPS. RESULTS A total of 163 patients treated with either VPS (74.2%) or LPS (25.8%) were identified. The mean follow-up was 35 mo. Shunt revision was required in 40.9% of patients. There was a nonsignificant higher rate of revision with LPS (52.4%) than VPS (36.4%, P = .07). In multivariate analysis, increasing patient age was associated with higher odds of shunt revision (P = .04). LPS had higher odds of shunt revision, yet this association was not significant (P = .06). Shunt malfunction was the main indication for revision occurring in 32.7%, with a significantly higher rate with LPS than VPS (P = .03). In total, 15 patients had shunt infection (9.4% VPS vs 12.2% LPS P = .50). The only significant predictor of procedural infection was the increasing number of revisions (P = .02). CONCLUSION The incidence of shunt revision was 40.9%, with increasing patient age as the sole predictor of shunt revision. The incidence of shunt malfunction was significantly higher in patients undergoing LPS, while there was no significant difference in the incidence of shunt infection between the 2 modalities.

OBJECTIVEWhile cerebrospinal fluid (CSF) shunt surgery plays an essential role in the treatment of hydrocephalus, postoperative infection due to the implantation of foreign materials is still one of the most common and potentially serious complications of this procedure. Because no previously reported protocol has been proven to prevent postoperative infection after CSF shunt surgeries in adults, the authors investigated the effectiveness of a protocol introduced in their institution.METHODSA detailed standardized surgical protocol to prevent infection in patients undergoing CSF shunt surgeries was introduced in the authors’ institution in December 2011. The protocol included a series of detailed rules regarding the surgical procedure, the surgical environment to minimize contamination from air, double gloving, local injection of antibiotics, and postoperative management. The rate of CSF shunt infection during the 3 years after surgery before and after implementation of the protocol was compared in patients undergoing their first CSF shunt surgeries. The inclusion periods were from January 2006 to November 2011 for the preprotocol group and from December 2011 to December 2014 for the postprotocol group.RESULTSThe study included 124 preprotocol patients and 52 postprotocol patients. The mean patient age was 59 years in both groups, ranging from 40 days to 88 years. Comparison of patient background factors, including known risk factors for surgical site infections, showed no significant difference between the patient groups before and after implementation of the protocol. While 9 patients (7.3%) developed shunt infections before protocol implementation, no shunt infections (0%) were observed in patients who underwent surgery after protocol implementation. The difference was statistically significant (p = 0.047).CONCLUSIONSThe authors’ detailed protocol for CSF shunt surgeries was effective in preventing postoperative infection regardless of patient age.

Abstract OBJECTIVE The history, diagnosis, and therapy of idiopathic intracranial hypertension (IIH) (pseudotumor cerebri) are reviewed. Theories of pathogenesis are considered, the clinical presentation is described, and potential diagnostic and therapeutic challenges are explored. METHODS An extensive literature review of IIH and related conditions (secondary pseudotumor syndromes) was performed. The history of and rationale for the diagnosis and medical and surgical approaches to treatment are reviewed. Available outcome studies are presented. RESULTS Diagnosis of IIH requires that the modified Dandy criteria be satisfied. Multiple potential contributing causes of intracranial hypertension must be identified or excluded. The clinical presentation most often includes headaches and papilledema, but many other findings have been described. The most important goal of therapy is to prevent or arrest progressive visual loss. Medical therapies include alleviation of associated systemic diseases, discontinuation of contributing medications, provision of carbonic anhydrase inhibitors, and weight loss. Surgical therapies include lumboperitoneal shunting, ventriculoperitoneal shunting, and optic nerve sheath fenestration. On the basis of the advantages and disadvantages of these treatment modalities, a suggested treatment paradigm is presented. CONCLUSION Idiopathic intracranial hypertension is the term to be adopted instead of pseudotumor cerebri. IIH remains an enigmatic diagnosis of exclusion. However, prompt diagnosis and thorough evaluation and treatment are crucial for preventing visual loss and improving associated symptoms.

Olfactory neuroblastoma (ONB) is a rare neuroepithelial-derived malignancy that usually presents in the nasal cavity. The rarity of ONB has led to conflicting reports regarding associations of patient age and ONB survival and outcome. Moreover, long-term outcomes of chemotherapy and other treatment modalities are speculated. Here, we aimed to compare survival outcomes across age groups through time and determine associations between treatment modality and survival. In this retrospective population-based study, we analyzed the SEER 2000–2016 Database for patients with ONB tumors. Using Kaplan–Meier survival analysis, a significant effect of age and cancer-specific survival (CSS) was observed; geriatric ONB patients had the lowest CSS overall. Generalized linear models and survival analyses demonstrated that CSS of the pediatric patient population was similar to the geriatric group through 100 months but plateaued thereafter and was the highest of all age groups. Radiation and surgery were associated with increased CSS, while chemotherapy was associated with decreased CSS. GLM results showed that tumor grade, stage and lymph node involvement had no CSS associations with age or treatment modality. Our results provide insight for future investigations of long-term outcomes associated with ONB patient age and treatment modality, and we conclude that survival statistics of ONB patients should be analyzed in terms of trends through time rather than fixed in time.

PurposeTo evaluate the value of F-18 FDG PET/CT in the differentiation of malignant and benign upper urinary tract-occupying lesions.Patients and Methods64 patients with upper urinary tract-occupying lesions underwent F-18 FDG PET/CT at RenJi Hospital from January 2015 to February 2019 in this retrospective study. Of the 64 patients, 50 patients received nephroureterectomy or partial ureterectomy; 14 patients received ureteroscopy and biopsy. The comparisons of PET/CT parameters and clinical characteristics between malignant and benign upper urinary tract-occupying lesions were investigated.ResultsOf the 64 patients, 49 were found to have malignant tumors. Receiver operating characteristic analysis determined the lesion SUVmax value of 6.75 as the threshold for predicting malignant tumors. There were significant associations between malignant and benign upper urinary tract-occupying lesions and SUVmax of lesion (P<0.001), lesion size (P<0.001), and patient age (P=0.011). Multivariate analysis showed that SUVmax of lesion (P=0.042) and patient age (P=0.009) as independent predictors for differentiation of malignant from benign upper urinary tract-occupying lesions. There was a significant difference in tumor size between the positive (SUVmax >6.75) and negative (SUVmax ≤6.75) PET groups in 38 of the 49 patients with malignant tumors.ConclusionThe SUVmax of lesion and patient age is associated with the nature of upper urinary tract-occupying lesions. F-18 FDG PET/CT may be useful to distinguish between malignant and benign upper urinary tract-occupying lesions and determine a suitable therapeutic strategy.

INTRODUCTION: Ventriculo-peritoneal shunt infection is the most important complication of shunt applications. In pediatric age, shunt infections are associated with shunt dysfunction, requirement for shunt revision, neurodevelopmental delay, prolonged hospital stay, and high treatment costs. In this study, we aimed to evaluate the characteristics of shunt infections of our patients and to compare the differences between early and late infections, infections caused by staphylococci and other strains and infection that did and did not recur. METHODS: In this retrospective study, shunt infections treated in the Pediatric Infection Clinic of Hamidiye Etfal Training and Research Hospital between July 2008 and July 2011 were evaluated. RESULTS: Forty-seven shunt infections in 42 patients were evaluated. Congenital anomalies were the most common etiology of hydrocephalus and fever was the most common symptom of the patients. Higher rates of early shunt infections, shunt infections in early childhood and infections caused by staphylococci species were observed. Patients with infections caused by staphylococci species received shorter duration of antibiotherapy (p=0.024). Infections that recurred in the six months of follow-up had higher rates of positive blood cultures (p=0.022). There was no statistically significant difference between early and late-term shunt infections. DISCUSSION AND CONCLUSION: Shunt infections were evaluated in different aspects in our study. Direct colonization of the shunt catheter still seems to be most important cause for the shunt infections because early infections and infections caused by skin flora were more common in our patient group.

Background: Essential Tremor (ET) is the most common movement disorder, yet the location of the primary disease substrate continues to be a matter of debate. In this study, we aimed to evaluate ocular movement abnormalities with Electrooculography (EOG) in patients with ET to find a possible location of disease pathology. Methods: Electrooculographic evaluation including saccade, tracking, optokinetic, gaze and positional tests were performed to 36 ET patients and 36 healthy subjects. Patient age on the onset of the tremor, duration of the disease, characteristics and the location of the tremor were also investigated. Fahn- Tolosa-Marin tremor rating scale was used to determine the tremor severity. Differences of abnormal test results between patient and control groups were analysed with Pearson’s and Fisher’s Exact and correlation analyses of EOG tests and clinical data were performed with Spearman’s and Pearson’s correlation tests. Results: There was not any significant difference in EOG tests between the ET patients and controls. Significant correlation was only found between EOG abnormality and patient age in correlation analyses. Conclusions: Our results showed that ET patients may not have specific EOG test abnormalities. These tests would be used especially in the different diagnosis of other movement disorders.

OBJECTIVE Children whose ventricles do not change during shunt malfunction present a diagnostic dilemma. This study was performed to identify risk factors for unchanged ventricular size at shunt malfunction. METHODS This retrospective 1:1 age-matched case-control study identified children with shunted hydrocephalus who underwent shunt revision with intraoperative evidence of malfunction at one of the three participating institutions from 1997 to 2019. Cases were defined as patients with a change of < 0.05 in the frontal–occipital horn ratio (FOR) between malfunction and baseline, and controls included patients with FOR changes ≥ 0.05. The presence of infection, abdominal pseudocyst, pseudomeningocele, or wound drainage and lack of baseline cranial imaging at the time of malfunction warranted exclusion. RESULTS Of 450 included patients, 60% were male, 73% were Caucasian, and 67% had an occipital shunt. The median age was 4.3 (IQR 0.97–9.21) years at malfunction. On univariable analysis, unchanged ventricles at malfunction were associated with a frontal shunt (41% vs 28%, p < 0.001), programmable valve (17% vs 9%, p = 0.011), nonsiphoning shunt (85% vs 66%, p < 0.001), larger baseline FOR (0.44 ± 0.12 vs 0.38 ± 0.11, p < 0.001), no prior shunt infection (87% vs 76%, p = 0.003), and no prior shunt revisions (68% vs 52%, p < 0.001). On multivariable analysis with collinear variables removed, patients with a frontal shunt (OR 1.67, 95% CI 1.08–2.70, p = 0.037), programmable valve (OR 2.63, 95% CI 1.32–5.26, p = 0.007), nonsiphoning shunt at malfunction (OR 2.76, 95% CI 1.63–4.67, p < 0.001), larger baseline FOR (OR 3.13, 95% CI 2.21–4.43, p < 0.001), and no prior shunt infection (OR 2.34, 95% CI 1.27–4.30, p = 0.007) were more likely to have unchanged ventricles at malfunction. CONCLUSIONS In a multicenter cohort of children with shunt malfunction, those with a frontal shunt, programmable valve, nonsiphoning shunt, baseline large ventricles, and no prior shunt infection were more likely than others to have unchanged ventricles at shunt failure.

Abstract INTRODUCTION Both CRASH and IMPACT models have been developed in recent years to predict the outcome of Traumatic Brain Injury (TBI). However, there is no clear evidence as to how these models perform in a modern cohort of UK-patients. There is also predictive uncertainty with regards to survival rates and functional outcome in elderly (>65 yr) patients. METHODS Patients referred to a tertiary neuroscience center from December 2014 to January 2016 with a suspected TBI were retrospectively examined. For each model, the predicted survival and overall outcome were compared to the actual outcome on admission and at 6 mo post injury, stratified by patient age (>65 yr vs ≤65 yr). RESULTS A total of 161 patients met the initial criteria; mean age 65 yr (SD = 21) and 110 male. Both CRASH and IMPACT correctly predicted 6-mo mortality rates and functional outcomes in most patients (range 61.7%-82.4%), with better predictive performance for patients not accepted to the center (range 84%-98%). There was no significant difference in the initial survival of elderly patients if accepted (78% [95% CI 50.6-104.0] vs 81% [95% CI 67.8-94.8] but were lower for those not accepted (24% [95% CI 4.2-43.7] vs 76% [95% CI 63.5-88.5], P = .027). CONCLUSION Patients >65 yr admitted to tertiary neuroscience center had good survival rates on admission and at 6 mo. The lesser ability of CRASH and IMPACT models to predict poorer outcomes when accepted suggests that acceptance to specialist centers may be able to improve outcome and suggests more optimistic treatment and acceptance of appropriate over 65 yr should be considered.

Ventriculoperitoneal Shunting

Abstract OBJECTIVE Recent reports have shown promising short- to medium-term results in patients with refractory idiopathic intracranial hypertension (IIH) treated using the stereotactic ventriculoperitoneal shunting (SVPS) technique. However, the long-term clinical efficacy of this technique remains questionable. This report provides the long-term results of SVPS in treating refractory IIH patients. METHODS We reviewed the medical charts of nine consecutive patients (mean age, 26.4 yr; range, 4–63 yr) treated using either a frame-based or frameless SVPS technique for IIH. RESULTS The mean postoperative follow-up period was 44.3 months (range, 6–110 mo). Before shunting procedures were performed, each patient presented with intractable headache, and five patients (55.6%) had mild to moderate visual deficits. The last follow-up assessment showed that after shunting was performed, eight patients (89%) were headache-free. Only one patient had recurrent headache; however, this patient's pain was much less frequent and severe than before the shunting procedure was completed and was concomitant with recent weight increase. Visual deficits were resolved in three patients and remained stable in two who already had optic nerve atrophy before shunting was completed. Twelve SVPS procedures were performed on our patients. Nine shunt revisions were needed in six patients because of infection (n = 5, including two revisions in one patient), valve dysfunction (n = 2), distal obstruction (n = 1), and ventricular catheter malpositioning (n = 1). No patient had proximal catheter obstruction. CONCLUSION Given the favorable long-term outcome of the SVPS technique for refractory IIH, we are encouraged to apply this procedure on our patients. More invasive approaches should be reserved for patients who have SVPS failure.
