Abstract
Surgical site infections (SSI) represent a considerable burden for healthcare systems. Studies show retrograde infection of the drainage tube is an important cause of surgical site infection. To this end, Surgeons work in various ways to reduce the incidence of retrograde infections. Fast progress in nanoscience and nanotechnology is revolutionizing the field of medicine to improve the quality of life due to the myriad of applications stemming from their unique properties, including the antibacterial activity against pathogens. Herein, we investigate the antibacterial properties of a novel nanomaterial composed of nano zinc oxide-decorated latex drainages. These materials were produced by the hydrothermal method and characterized through field-emission scanning electron microscopy (FE-SEM), X-ray diffraction (XRD), and DLS (Dynamic light scattering techniques). Then inductively coupled plasma mass spectrometry (ICP-MS) measurements showed that nano zinc oxide on the surface of the latex drainages showed a gradient release process. The antimicrobial activity of nano zinc oxide -decorated latex drainage was evaluated against E. coli and Staphylococcus aureus, the main bacteriological agent in the retrograde infection associated with drainage. The results showed that slices and rods nano zinc oxide (SAR-ZnO) drainage tubes had the best antibacterial properties both in vivo and in vitro. In addition, the cell viability assay demonstrated that nano zinc oxide-decorated latex drainages exerted good biocompatibility. Therefore, SAR-ZnO drainage tubes can be a perfect nanomaterial against the retrograde infection associated with drainage.

Abstract
INTRODUCTION Lumbar drains are frequently used in patients with otolaryngologic concerns. These can be used therapeutically or prophylactically with the primary purpose being to modulate CSF pressure. Within otolaryngology, lumbar drains are most frequently used for cerebrospinal fluid leaks - either due to cerebrospinal fluid fistulas or in skull base surgery as these allow for potential healing of the defect. While not typically placed by otolaryngologists, a basic understanding of lumbar drains is beneficial in the context of patient management. MANAGEMENT A lumbar drain is inserted into the intrathecal space in a patient's lumbar spine. Though considered to be a benign procedure, complications are relatively frequent, and adjustment or replacement of the drain may be required. Complications include infection, epidural bleeding, retained hardware, sequelae of relative immobility, or may relate to over-drainage, ranging from mild headache to cranial neuropathies, altered mental status, pneumocephalus, intracranial hemorrhage, and death. While in place, neurologic exams should be performed routinely and should include motor and sensory exams of the lower extremities. A patient should be monitored for fevers, nuchal rigidity, and other signs of infection or meningitis. The CSF fluid should be grossly examined to identify changes, but routine laboratory tests are not typically run on the fluid itself. Drainage rates will vary usually between 5 and 20 mL per hour and must be frequently reassessed and adjusted based upon signs of intracranial hypotension. Drains should be removed when appropriate and should not be left in more than 5 days due to the increased infectious risk. CONCLUSION Lumbar drains are important tools used in patients with otolaryngologic pathologies. Otolaryngologists and otolaryngology residents should be familiar with these catheters to determine if they are working correctly and to identify adverse effects as early as possible.

Abstract
OBJECTIVES Cerebral infections related to the presence of an intraparenchymal intracranial pressure transducer (ICPT) are rare. We assessed the incidence of ICPT-related infections and colonization using culture, molecular biology, and electron microscopy. METHODS All consecutive patients in a neurosurgical intensive care unit who had an ICPT inserted between March 2017 and February 2018 were prospectively included. Presence of colonization on the ICPTs was assessed after removal using culture, scanning electron microscopy (SEM), and next-generation sequencing (NGS). RESULTS Fifty-three ICPTs (53 patients), indwelling for a median of 4 (range 3-7) days, were studied. Median patient follow-up was 3 months. SEM, microbial culture, and NGS were performed for 91%, 79%, and 72% of ICPTs, respectively; 28 ICPTs (53%) were assessed using all three techniques. No patient developed ICPT-related infection. Microbial cultures were positive for two of the ICPTs (5%); colonization was identified on all ICPTs using NGS and SEM. Mature biofilm was observed on 35/48 (73%) of ICPTs. A median of 10 (8-12) operational taxonomic units were identified for each ICPT, most being of environmental origin. There was no association between biofilm maturity and antimicrobial treatment or duration of ICPT insertion. Antimicrobial treatment was associated with decreased alpha and beta-diversity (p = 0.01). CONCLUSIONS We observed no ICPT-related cerebral infections although colonization was identified on all ICPTs using NGS and SEM. Mature biofilm was the main bacterial lifestyle on the ICPTs.

Abstract
OBJECTIVE Surgical site infections (SSIs) carry significant patient morbidity and mortality and are a major source of readmissions after craniotomy. Because of their deleterious effects on health care outcomes and costs, identifying modifiable risk factors holds tremendous value. However, because SSIs after craniotomy are rare and most existing data comprise single-institution studies with small sample sizes, many are likely underpowered to discern for such factors. The objective of this study was to use a large hetereogenous patient sample to determine SSI incidence after nonemergent craniotomy and identify factors associated with readmission and subsequent need for wound washout. METHODS We used the 2010-2014 Nationwide Readmissions Database cohorts to discern for factors predictive of SSI and washout. RESULTS We identified 93,920 nonemergent craniotomies. There were 2079 cases of SSI (2.2%) and 835 reoperations for washout (0.89%) within 30 days of index admission and there were 2761 cases of SSI (3.6%) and 1220 reoperations for washout (1.58%) within 90 days. Several factors were predictive of SSI in multivariate analysis, including tumor operations, external ventricular drain (EVD), age, length of stay, diabetes, discharge to an intermediate-care facility, insurance type, and hospital bed size. Many of these factors were similarly implicated in reoperation for washout. CONCLUSIONS SSI incidence in neurosurgery is low and most readmissions occur within 30 days. Several factors predicted SSI after craniotomy, including operations for tumor, younger age, hospitalization length, diabetes, discharge to institutional care, larger hospital bed size, Medicaid insurance, and presence of an EVD. Diabetes and EVD placement may represent modifiable factors that could be explored in subsequent prospective studies for their associations with cranial SSIs.

Abstract
Introduction: Ventriculostomy-related infection (VRI) from external ventricular drain (EVD) insertion is a common complication and carries a high mortality rate. Choice of empiric antibiotics depends on the institutions common causative organisms and their susceptibility. We determined risk factors for mortality in patients with VRI, the common organisms causing VRI, and the rate of EVD-related VRI at our institution. Methods: Medical records and operative data of patients with cerebrospinal fluid positive cultures with an EVD inserted from 2012 to 2015 were traced. Forty-five patients with EVD-related VRI were included in the study. Results: The overall rate of VRI was 6.3%, and the overall mortality rate due to VRI was 48.9%. Acinetobacter baumannii was the most common organism causing VRI (14 patients, 29.2%) with a mortality rate of 64.3%. Only 14.3% of A. baumannii are sensitive to meropenem and imipenem. We found that patients that had a decompressive craniectomy (DC) had a lower mortality rate (P = 0.042) and patients with a longer duration of the EVD being in place before the diagnosis of VRI had poor outcome (P = 0.040). Multivariate logistic regression was performed and we found that the use of steroid (P = 0.014), Pseudomonas aeruginosa infection (P = 0.010), multiple organism infection (P = 0.017), lower Glasgow Coma Scale (P = 0.043), and a longer duration the EVD was in place before the diagnosis of VRI (P = 0.008) were related with higher mortality. Conclusion: VRI mortality rate is high with an alarming resistance pattern seen in Acinetobacter VRI. EVDs should be removed as soon as feasible, and DC may be offered to patients with severe ventriculitis or meningitis.

Abstract
Context: Hydrocephalus, due to subarachnoid or intraventricular hemorrhage (IVH), meningitis, or tumor compression, is usually transient and may resolve after treatment. There are several temporary methods of cerebrospinal fluid (CSF) diversion, none of it is superior to the other, and the decision is based on its various etiologies and factors. Ventriculosubgaleal shunt (VSGS) is one of those temporary measures, which is a simple and rapid CSF decompression method without causing electrolyte and nutritional losses. Aims: The aim is to study the efficacy of VSGS for temporary CSF diversion, compared to extraventricular drainage (EVD) in adult hydrocephalus patients; to evaluate the outcome in terms of avoiding a permanent shunt, and to look for incidences of their complications. Settings and Design: This was a retrospective observational study. Subjects and Methods: The data were acquired from case notes of fifty patients with acute hydrocephalus: 26 secondary to IVH, 10 from aneurysm rupture, 8 posttrauma, and 6 from infection. All these patients had undergone CSF diversion in Hospital Queen Elizabeth II, Sabah, Malaysia, between 2013 and 2015. The patients were followed up from the date of treatment until the resolution of hydrocephalus, where parameters such as shunt dependency and complications were documented. Statistical Analysis Used: All analyses were carried out using Statistical Packages for the Social Sciences Version 22.0. Chi-squared test or Fisher's exact test is used for univariate analysis of categorical variables. Results: A total of 21 (42%) patients underwent EVD insertion and 29 (58%) underwent VSGS insertion. Thirty-seven (74%) patients did not require a permanent shunt; 24 (64.8%) of them were from the VSGS group (P = 0.097). EVD had more intracranial complications (44.1%) compared with VSGS (23.5%), with a statistically significant P = 0.026. Conclusions: VSGS is a safe and viable option for adult hydrocephalus patients, with the possibility of continuation of the treatment for such patients in nonneurosurgical centers, as opposed to patients with EVDs. Furthermore, even though this method had no statistical difference in avoiding a permanent ventriculoperitoneal shunt, VSGS has statistically significant less intracranial complications compared with EVD.

Abstract
STUDY DESIGN The efficacy of use of a drain tip culture for early detection of surgical-site infection (SSI) was investigated in 329 patients after spinal surgery. OBJECTIVE To examine the efficacy of a wound drain tip culture for detection of SSI in spinal surgery. SUMMARY OF BACKGROUND DATA A complication of SSI after spinal surgery has high associated morbidity and mortality, and is often difficult to treat. MATERIALS AND METHODS The subjects were patients who underwent spinal surgery at our institution between January 2010 and March 2013. All subjects were treated with antimicrobial prophylaxis based on evidence-based guidelines and were followed for at least 6 months after surgery. Data from culture studies using the distal tip of the wound drain were used for analysis. RESULTS Drain tip cultures were positive in 34 cases and there were 19 SSIs. Ten of the 34-tip culture-positive wounds developed SSI. Drain tip cultures had a sensitivity of 52%, specificity of 92%, positive predictive value (PPV) of 29%, and negative predictive value of 97% for predicting a wound infection. The association between a positive suction tip culture and wound infection was significant (P<0.05). The PPV for SSI was 60% in cases in which methicillin-resistant bacteria were detected in a drain tip, and the SSI rate in these cases differed significantly compared with those with non-methicillin-resistant bacteria (P=0.01). CONCLUSIONS A drain tip culture is useful for early detection of SSI caused by methicillin-resistant bacteria.

Abstract
Ventriculostomy-related infection (VRI) is a serious complication of external ventricular drain (EVD) but its natural history is poorly studied. We prospectively tracked the bacteria pathways from skin towards ventricles to identify the infectious process resulting in ventriculostomy-related colonization (VRC), and VRI. We systematically sampled cerebrospinal fluid (CSF) on a daily basis and collected swabs from both the skin and stopcock every 3.0 days for microbiological analysis including in 101 neurosurgical patient. Risk factors for positive event defined as either VRC or VRI were recorded and related to our microbiological findings. A total of 1261 CSF samples, 473 skin swabs, and 450 stopcock swabs were collected. Skin site was more frequently colonized than stopcock (70 (60%) vs 34 (29%), p = 0.023), and earlier (14 ±1.4 vs 24 ±1.5 days, p<0.0001). Sixty-one (52%) and 32 (27%) skin and stopcock sites were colonized with commensal bacteria, 1 (1%) and 1 (1%) with pathogens, 8 (7%) and 1 (1%) with combined pathogens and commensal bacteria, respectively. Sixteen positive events were diagnosed; a cutaneous origin was identified in 69% of cases. The presence of a pathogen at skin site (6/16 vs 4/85, OR: 11.8, [2.5–56.8], p = 0.002) and CSF leakage (7/16 vs 6/85, OR 10 [2.4–41.2], p = 0.001)) were the two independent significant risk factors statistically linked to positive events occurrence. Our results suggest that VRC and VRI mainly results from an extra-luminal progression of pathogens initially colonizing the skin site where CSF leaks.

Risk factors of surgical site infections after supratentorial elective surgery: a focus on the efficacy of the wound-drain-tip culture. Acta Neurochir (Wien) 2013; 155:2165-70; discussion 2170.

Abstract
BACKGROUND Surgical site infection (SSI) is one of the most dangerous complications after neurological surgery and is related to additional postoperative hospital days and an increased risk of death. One method for the early detection of SSI, the wound-drain-tip culture (WDC), has been widely used. However, no investigations on the relation between SSIs and wound drains after neurological surgery have been conducted. We performed this study to identify the risk factors for SSIs and to assess the relationship between SSIs and the results of WDC after elective supratentorial craniotomy. METHODS A total of 535 patients underwent elective primary supratentorial craniotomy, and the results of their WDC were analyzed. The mean follow-up period was 14.1 ± 12.2 months. In 347 (64.9 %) patients, the wound drain was removed within 2 days after operation. RESULTS Until follow-up, 14 (2.62 %) patients suffered from SSIs. Among the 21 patients with positive WDCs, 8 (38.1 %) patients experienced SSIs. The organisms cultured from the SSIs were matched with the WDC results in 7 (87.5 %) patients. In the multivariate analysis, underweight group (OR = 15.41, p = 0.002), maintenance wound drain over 3 days (OR = 4.202, p = 0.043), and positive WDC (OR = 36.67, p < 0.001) were significantly associated with postoperative SSIs. In 6 (85.7 %) of 7 patients with a positive WDC for Serratia marcescens, SSIs ultimately developed. CONCLUSIONS The prognostic value of the positive WDC still falls short of our expectations in the field of neurological surgery. And, the positive WDC results should be cautiously interpreted, considering the virulence of the cultured micro-organisms.

Abstract
PURPOSE OF REVIEW The review touches upon the current physiopathological concepts relating to the field of intracranial pressure (ICP) monitoring and offers an up-to-date overview of the ICP monitoring technologies and of the signal-analysis techniques relevant to clinical practice. RECENT FINDINGS Improved ICP probes, antibiotic-impregnated ventricular catheters and multimodality, computerized systems allow ICP monitoring and individualized optimization of brain physiology. Noninvasive technologies for ICP and cerebral perfusion pressure assessment are being tested in the clinical arena. Computerized morphological analysis of the ICP pulse-waveform can provide an indicator of global cerebral perfusion. SUMMARY Current recommendations for the management of traumatic brain injury indicate ICP monitoring in patients who remain comatose after resuscitation if the admission computed tomography scan reveals intracranial abnormalities such as haematomas, contusions and cerebral oedema. The most reliable methods of ICP monitoring are ventricular catheters and intraparenchymal systems. A growing number of these devices are being safely placed by neurointensivists. The consensus is to treat ICP exceeding the 20 mmHg threshold, and to target cerebral perfusion pressure between 50 and 70 mmHg. Recent evidence suggests that such thresholds should be optimized based on multimodality monitoring and individual brain physiology. Noninvasive ICP estimation using transcranial Doppler can have a role as a screening tool in patients with low to intermediate risk of developing intracranial hypertension. However, the technology remains insufficiently accurate and too cumbersome for continuous ICP monitoring.
