Introduction: Planning cranioplasty (CPL) in patients with suspected or proven post-traumatic hydrocephalus (PTH) poses a significant management challenge due to a lack of clear guidance., Research Question: This project aims to create a European document to improve adherence and adapt to local protocols based on available resources and national health systems., Methods: After a thorough non-systematic review, a steering committee (SC) formed a European expert panel (EP) for a two-round questionnaire using the Delphi method. The questionnaire employed a 9-point Likert scale to assess the appropriateness of statements inherent to two sections: "Diagnostic criteria for PTH" and "Surgical strategies for PTH and cranial reconstruction.", Results: The panel reached a consensus on 29 statements. In the "Diagnostic criteria for PTH" section, five statements were deemed "appropriate" (consensus 74.2-90.3 %), two were labeled "inappropriate," and seven were marked as "uncertain."In the "Surgical strategies for PTH and cranial reconstruction" section, four statements were considered "appropriate" (consensus 74.2-90.4 %), six were "inappropriate," and five were "uncertain.", Discussion and Conclusion: Planning a cranioplasty alongside hydrocephalus remains a significant challenge in neurosurgery. Our consensus conference suggests that, in patients with cranial decompression and suspected hydrocephalus, the most suitable diagnostic approach involves a combination of evolving clinical conditions and neuroradiological imaging. The recommended management sequence prioritizes cranial reconstruction, with the option of a ventriculoperitoneal shunt when needed, preferably with a programmable valve. We strongly recommend to adopt local protocols based on expert consensus, such as this, to guide patient care., Competing Interests: No conflict of interest is to be disclosed by Salvatore Chibbaro, Thomas Sauvigny, Ivan Timofeev, Harry Mee, and Ismail Zaed.

Background: Brain edema and/or acute hydrocephalus are common features that limit working space during early surgery of aneurysmal subarachnoid hemorrhage (aSAH). Intraoperative ventriculostomy offers an immediate brain relaxation. However, management and complications related to the routine use of intraoperative external ventricular drainage (iEVD) are not well investigated., Methods: We retrospectively reviewed all patients who were treated with pterional craniotomy and clipping for ruptured anterior circulation aneurysms in our center between 2012 and 2019. We included in this study all patients submitted to iEVD using the Paine's point on the side of craniotomy. Indication for positioning of an iEVD was given in all cases whenever initial cisternal dissection was hampered by the lack of cerebrospinal fluid (CSF) circulation due to SAH and/or hydrocephalus., Results: In the study period, 162 patients with aSAH underwent surgical clipping. In 103 patients, an iEVD was used. The overall rate of iEVD-related complications was 6.7%, including 3 cases of catheter misplacement, one case of catheter obstruction, one case of related hemorrhage, and 2 cases of infection. The rate of shunt-dependent hydrocephalus was 16.5% (17/103 patients)., Conclusion: In our experience, iEVD is a safe technique that facilitates dissection during early surgery for intracranial ruptured aneurysms, without requiring an additional burr hole procedure., (© 2022.

Gastric cancer (GC) is the fifth most commonly diagnosed malignancy and the fourth leading cause of cancer death worldwide. Skin metastases from internal organs are rare; skin metastasis from GC occurs even more rarely than skin metastases originating from other organs, and is associated with systematic disease and poor prognosis. The present study described an interesting and rare case of an extensive skin rash in a 42-year-old man diagnosed with GC, which was mainly affecting his left hemithorax, abdomen and back. The rash masqueraded as erysipelas and was initially treated as such; however, it did not respond to antibiotics, corticosteroids and antihistamines. Due to its persistence and location, the rash was biopsied and GC metastasis was confirmed. Third-line chemotherapy was administered and the rash decreased in size; however, the patient suffered from disease deterioration with lung metastases and respiratory failure. The patient eventually died 4 months after the diagnosis of skin metastasis. In conclusion, cutaneous metastasis should be considered as a late and difficult to treat metastasis of GC, which requires high surveillance from medical oncologists, and a multidisciplinary approach for prompt and accurate diagnosis., Competing Interests: The authors declare that they have no competing interests., (Copyright © 2020, Spandidos Publications.)

Objective: Chronic subdural hematoma (CSDH) is one of the most common pathology in daily neurosurgical practice and incidence increases with age. The aim of this study was to evaluate the prognostic factors and surgical outcome of CSDH in patients aging over 90 years compared with a control group of patients aging under 90 years., Methods: This study reviewed 25 patients with CSDH aged over 90 years of age treated in our department. This group was compared with a younger group of 25 patients aged below their eighties. At admission past medical history was recorded concerning comorbidities (hypertension, dementia, ictus cerebri, diabetes, and heart failure or attack). History of alcohol abuse, anticoagulant and antiplatelet therapy, head trauma and seizures were analyzed. Standard neurological examination and Markwalder score at admission, 48 hours after surgery and 1-6 months follow-up, radiologic data including location and CSDH maximum thickness were also evaluated., Results: Their mean age was 92.8 years and the median was 92.4 years (range, 90-100 years). In older group, the Markwalder evaluation at one month documented the complete recovery of 24 patients out of 25 without statistical difference with the younger group. This data was confirmed at 6-month follow-up. One patient died from cardiovascular failure 20 days after surgery. The presence of comorbidities, risk factors (antiplatelet therapy, anticoagulant therapy, history of alcohol abuse, and head trauma), preoperative symptoms, mono or bilateral CSDH, maximum thickness of hematoma, surgical time and recurrence were similar and statistically not significant in both groups., Conclusion: In this study, we demonstrate that surgery for very old patients above 90 years of age affected by CSDH is safe and allows complete recovery. Comparing two groups of patients above and under 90 years old we found that complication rate and recovery were similar in both groups.

Stereotactic gamma knife radiosurgery (GKS) may induce a transient enlargement of vestibular schwannomas (VS). This phenomenon, known as pseudoprogression or swelling, starts at about 3 months following GKS, peaks at about 6 months, and typically subsides thereafter, usually without significant neurological deterioration. We describe a 34-year-old female who developed an aggressive enlargement of a VS 1 month after GKS. The patient was treated with an immediate external ventricular drainage and surgical resection via retrosigmoid approach for an acute neurological deterioration due to hydrocephalus and brainstem compression. Histopathological examination revealed a VS with abundant intratumoral thrombosis and necrosis, suggesting that its rapid expansion could be related to massive radiation-induced tumor necrosis. The present case indicated that rapid life-threating enlargement of a VS may occur as an early complication following GKS.

Background: Do alterations of cerebrospinal fluid dynamics secondary to decompressive craniectomy (DC) lead to hydrocephalus, and can this effect be mitigated by early cranioplasty (CP)? In this meta-analysis, we evaluated whether the timing of CP decreased the incidence of postoperative hydrocephalus., Methods: We performed a systematic search of PubMed/MEDLINE, Scopus, and the Cochrane databases using Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines for English language articles (1990-2020). We included case series, case-control, and cohort studies, and clinical trials assessing the incidence of hydrocephalus in adult patients undergoing early CP (within 3 months) versus late CP (after 3 months) after DC., Results: Eleven studies matched the inclusion criteria. The rate of postoperative hydrocephalus was not significantly different between the early (=96/1063; 9.03%) and late CP (=65/966; 6.72%) group ( P = 0.09). Only in the three studies specifically reporting on the rate of hydrocephalus after DC performed to address traumatic brain injury (TBI) alone was there a significantly lower incidence of hydrocephalus with early CP ( P = 0.01)., Conclusion: Early CP (within 90 days) after DC performed in TBI patients alone was associated with a lower incidence of hydrocephalus. However, this finding was not corroborated in the remaining eight studies involving CP for pathology exclusive of TBI., Competing Interests: There are no conflicts of interest., (Copyright: © 2020 Surgical Neurology International.)

Background: Cervical spondylotic myelopathy (CSM) is one of the most common diseases in the geriatric population. Decompressive laminectomy or laminoplasty is the predominant surgical procedure of choice, but there remains debate as to which procedure is optimal for managing CSM., Methods: Here, we retrospectively analyzed 64 patients with CSM undergoing laminectomy (39 patients) versus laminoplasty (25 patients). The data were collected included respective Japanese orthopedic association (JOA) scores, Nurick grades, and Visual analog scale (VAS) values preoperatively versus 12 months postoperatively., Results: The JOA score after 1 month improved in both groups utilizing laminectomy or laminoplasty. However, at 12 postoperative months, the JOA scores and Nurick grades showed greater improvement following laminoplasty, despite no differences in postoperative pain and complication rates., Conclusion: Patients with cervical spondylotic myelopathy undergoing laminoplasty (25 patients) showed better 12-month postoperative outcomes (JOA scores and Nurick grades) versus those having laminectomies (39 patients)., Competing Interests: There are no conflicts of interest., (Copyright: © 2020 Surgical Neurology International.)

Background: Our hypothesis was that by identifying certain preoperative predictive factors, we could favorably impact clinical outcomes in patients undergoing decompressive surgery for lumbar spinal stenosis (LSS)., Methods: In this retrospective study, there were 65 patients (2016-2018) with symptomatic LSS who underwent decompressive laminectomy without fusion. Their clinical outcomes were assessed utilizing the Oswestry Disability Index (ODI). Multiple preoperative variables were studied to determine which ones would help predict improved outcomes: gender, age, body mass index (BMI), general/neurological examination, smoking, and drug therapies (anxiolytics and/or antidepressants)., Results: All patients demonstrated statistically significant improvement on the ODI. Multivariate analysis revealed that those with higher preoperative BMI had significantly lower ODI on 1-year follow-up examinations, reflecting poorer outcomes. Postoperatively, 44 patients (67%) exhibited lower utilization of anxiolytic medications, 52 patients (80%) showed reduced use of antidepressant drugs, and pain medications utilization was reduced in 33 patients (50%)., Conclusion: Decompressive laminectomy without fusion effectively managed LSS. It reduced patients' use of pain, anxiety, and antidepressant medications. In addition, we found that increased preoperative BMIs contributed to poorer postoperative outcomes (e.g., ODI values)., Competing Interests: There are no conflicts of interest., (Copyright: © 2020 Surgical Neurology International.)

Background: This study evaluated how the neurological outcome in patients operated on cervical spinal cord injury (SCI) was positively influenced by ultra-early surgery (UES)., Methods: Between 2010 and 2017, 81 patients with traumatic cervical SCI were assigned to the UES group (<12 h after injury; UES) and ES group (surgery between 12 and 48 h after injury; ES). Additional variables evaluated for the two groups included; age, sex, comorbidities charlson comorbidity index (CCI), level of trauma, type of fracture, preoperative and ASIA scores, pre- and post-operative neuroradiological examinations, surgical approaches, and complications., Results: Forty-seven of 81 (58.02%) patients exhibited improved neurological function 12 months postoperatively; better outcomes were observed in the UES (29 of 40 [72.5%]) versus ES groups (18 of 41 [43.9%]) ( P = 0,009). For the 26 patients with complete cervical SCI (ASIA A), ultra-early surgical decompression was associated with significantly greater neurological improvement versus ES (61.53% vs. 7.69%; P = 0.003). Further, more neurological improvement correlated with the younger age, better ASIA grade at admission, and ultra-early surgical timing (< 12 h) both in the univariate and multivariate analysis ( P = 0.037, P = 0.017, and P = 0.005, respectively), while CCI was correlated with improvement only in the univariate analysis ( P = 0.005)., Conclusion: Ultra-early surgical timing in SCI patients appeared to be the most important factor determining the extent of postoperative neurological improvement, particularly regarding motor function recovery., Competing Interests: There are no conflicts of interest., (Copyright: © 2019 Surgical Neurology International.)

Purpose: Primary squamous cell carcinoma (SCC) of the ovary is rare. Most cases arise from a cystic teratoma or less frequently from Brenner tumor or endometriosis. We reviewed 36 cases of primary ovarian SCC reported in the literature including a case diagnosed and treated in our institution., Methods: Data was collected by using the key-words "primary squamous cell carcinoma" and "ovary" on Google Scholar and PubMed in April 2018. All reviewed cases were analyzed according to diagnosis, surgical approach, adjuvant therapy and outcome., Results: To date 23 articles presenting 36 cases of primary ovarian SCC are reported. Nine patients had stage I, 8 stage II, 11 stage III and 5 stage IV disease, whereas 3 patients had in situ carcinoma. All patients underwent surgery (mainly hysterectomy with bilateral salpingo-oophorectomy). Adjuvant therapy was reported in 24 patients, 15 of which received chemotherapy, 6 radiotherapy and 3 a combination of both. Chemotherapy regimens were similar to the ones used in ovarian carcinoma (more often platinum plus paclitaxel). Follow-up period was in general short and survival varied between 9 days and 14 years, depending on the stage at diagnosis., Conclusions: Primary ovarian SCC is a rare entity with poor prognosis, compared to serous carcinoma. Treatment is usually extrapolated from classical ovarian carcinoma algorithms, including surgical management combined with adjuvant chemotherapy with or without radiotherapy. Further investigations are needed to define optimal treatment, such as chemotherapy regimens and the role of radiotherapy and lymph node dissection.

We present an unusual case of spinal neurinoma with intralesional and subarachnoid bleeding with acute cauda equina syndrome. A 38-year-old man was admitted to our department after a minor thoracic spinal trauma with right lower limb plegia and urinary retention. MRI showed a T11 intradural tumour with intralesional and subarachnoid haemorrhage. The patient was operated of spinal cord decompression and complete tumour resection. The histological examination documented a schwannoma with large haemorrhagic intratumoural areas. A full neurological recovery was documented at 6-month follow-up., Competing Interests: Competing interests: None declared., (© BMJ Publishing Group Limited 2019. No commercial re-use.

Treatment modalities affecting quality of life and survival in elderly brain glioblastoma patients are not well defined. A single-institution data were analyzed during a 3-year period to disclose prognostic difference in management related to age. Karnofsky Performance Scale (KPS), overall survival (OS), and adjuvant therapy were evaluated. The case group comprised of elderly patients (>75 years), while the control group included those of younger age (<65 years). The investigated variables were correlated between the groups. Twenty elderly patients and a corresponding number of younger ones were analyzed. Preoperative KPS >70 indicated longer overall survival. Statistically significant correlation was recorded in both the control (p=0.036) and case (p=0.0053) groups. Lower postoperative KPS was significantly correlated with shorter OS in elderly patients (p=0.023). The correlation between the extent of tumor resection and OS was statistically significant in younger patients only (p=0.04). Overall survival was significantly shorter in elderly patients regardless of the extent of tumor resection (p=0.0057). Adjuvant therapy was significantly associated with longer OS in both the case (p=0.032) and control (p=0.013) groups. Elderly population is a more endangered group of surgical brain glioblastoma patients having lower quality of life and shorter overall survival. The management protocol should be personalized for each individual case in this age group of patients to reduce postoperative complications and grant a satisfactory quality of life.

Background: This study identified risk factors and postoperative indicators for recurrent lumbar disc herniations (rLDH) following microdiscectomy., Methods: We retrospectively reviewed the 1-year recurrence rate for LDH in 209 consecutive patients undergoing microdiscectomy (2013-2018)., Results: Utilizing a multivariate analysis, higher body mass index (BMI) and postsurgery Oswestry disability index (ODI) were significantly associated with an increased risk of rLDH., Conclusion: Elevated postsurgery ODI and higher BMI were significantly associated with increased risk of rLDH., Competing Interests: There are no conflicts of interest.

Purpose: Ewing Sarcoma/Primitive Neuroectodermal Tumor (ES/PNET) is a malignant small round cell tumor belonging to the Ewing Sarcoma Family of Tumors. It occurs more commonly in children and young adults. Its localization in the adrenal gland is extremely rare. We reviewed 35 cases of ES/PNET of the adrenal gland reported in the literature and presented our case., Methods: Data were collected by searching for ES/PNET and adrenal gland key words on Google Scholar and PubMed in March 2018, including a case diagnosed in our department. We analyzed all reviewed cases for diagnosis, surgical and systemic therapy and outcome., Results: To date 24 articles presenting cases of ES/PNET of the adrenal gland are reported in the literature. We included in our review 35 cases previously described and one new case. Histologically all cases consisted of sheets of small round cells. Immunohistochemistry was also performed in all cases. Most cases stained positive for CD99 and negative for lymphocytic markers. Markers of epithelial differentiation displayed variable results. In all cases tested, characteristic translocations were displayed supporting the diagnosis. All patients but four were treated surgically and the majority received adjuvant therapy. Only very few cases received neoadjuvant chemotherapy., Conclusions: Primary ES/PNET of the adrenal gland is a rare tumor, showing specific morphological, immunohistochemical and cytogenetic characteristics. Treatment consists of surgery, chemotherapy and radiotherapy. Further investigations paired with long term follow-up are necessary to define prognosis for this rare entity.

Metastases involving the clivus and craniocervical junction (CCJ) are extremely rare. Skull base involvement can result in cranial nerve palsies, while an extensive CCJ involvement can lead to spinal instability. We describe an unusual case of clival and CCJ metastases presenting with VI cranial nerve palsy and neck pain secondary to CCJ instability from metastatic bladder urothelial carcinoma. The patient was first treated with an endoscopic endonasal approach to the clivus for decompression of the VI cranial nerve and then with occipitocervical fixation and fusion to treat CCJ instability. At the 6-month follow-up, the patient experienced complete recovery of VI cranial nerve palsy. To the best of our knowledge, the simultaneous involvement of the clivus and the CCJ due to metastatic bladder carcinoma has never been reported in the literature. Another peculiarity of this case was the presence of both VI cranial nerve deficit and spinal instability. For this reason, the choice of treatment and timing were challenging. In fact, in case of no neurological deficit and spinal stability, palliative chemo- and radiotherapy are usually indicated. In our patient, the presence of progressive diplopia due to VI cranial nerve palsy required an emergent surgical decompression. In this scenario, the extended endoscopic endonasal approach was chosen as a minimally invasive approach to decompress the VI cranial nerve. Posterior occipitocervical stabilization is highly effective in avoiding patient's neck pain and spinal instability, representing the approach of choice., Competing Interests: There are no potential conflicts of interest for any of the authors with products or techniques discussed in the paper.

Coil migration and extrusion outside the cranial compartment after embolization of cerebral aneurysms represents a very rare complication of the endovascular procedures and few cases are reported in the literature. Instability of the vascular malformation wall and the resolution of the intramural hematoma, especially in pseudoaneurysm, might generate extravascular migration of the coils in the first months after embolization. However, to the best of our knowledge, an extrusion of coil 10 years after embolization has never been reported. We reported the unique case of a patient with coil extrusion into the naso- and oropharynx 10 years after internal carotid artery pseudoaneurysm embolization. The pseudoaneurysm occurred after an internal carotid artery injury during an endoscopic endonasal surgery for a clival giant cell tumor.

Background: The development or expansion of a cerebral hemorrhagic contusion after decompressive craniectomy (DC) for traumatic brain injury (TBI) occurs commonly and it can result in an unfavorable outcome. However, risk factors predicting contusion expansion after DC are still uncertain. The aim of this study was to identify the factors associated with the growth or expansion of hemorrhagic contusion after DC in TBI. Then we evaluated the impact of contusion progression on outcome. Methods: We collected the data of patients treated with DC for TBI in our Center. Then we analyzed the risk factors associated with the growth or expansion of a hemorrhagic contusion after DC. Results: 182 patients (149 males and 41 females) were included in this study. Hemorrhagic contusions were detected on the initial CT scan or in the last CT scan before surgery in 103 out of 182 patients. New or blossoming hemorrhagic contusions were registered after DC in 47 patients out of 182 (25.82%). At multivariate analysis, only the presence of an acute subdural hematoma ( p = 0.0076) and a total volume of contusions >20 cc before DC ( p = < 0.0001) were significantly associated with blossoming contusions. The total volume of contusions before DC resulted to have higher accuracy and ability to predict postoperative blossoming of contusion with strong statistical significance rather than the presence of acute subdural hematoma (these risk factors presented respectively an area under the curve [AUC] of 0.896 vs. 0.595; P < 0.001). Patients with blossoming contusions presented an unfavorable outcome compared to patients without contusion progression ( p < 0.0185). Conclusions: The presence of an acute subdural hematoma was associated with an increasing rate of new or expanded hemorrhagic contusions after DC. The total volume of hemorrhagic contusions > 20 cc before surgery was an independent and extremely accurate predictive radiological sign of contusion blossoming in decompressed patients for severe TBI. After DC, the patients who develop new or expanding contusions presented an increased risk for unfavorable outcome.

We present a case of Zenker's diverticulum in a 45-year-old woman, occurred as complication after anterior cervical discectomy and fusion for a cervical spine injury. The oesophageal complication occurred 12 months after vertebral cervical surgery and presenting symptoms were fever, dysphagia and neck pain with evidence of retropharyngeal infection. We performed a posterior cervical stabilisation C3-D1 by screws and rods and a second anterior left cervical approach with anterior plate removing and oesophageal wall break repairing with a sternohyoid muscle patch. Despite pharyngo-oesophageal diverticulum may be a complication of anterior cervical surgery (traction diverticulum), in case of an already present true Zenker's diverticulum, delayed complication may occur without cervical hardware pull-out., Competing Interests: Competing interests: None declared., (© BMJ Publishing Group Limited 2018.

Ovarian metastasis is common with secondary tumors representing up to 15% of ovarian neoplasms. The malignancies most commonly involving the ovaries are carcinomas of the stomach, colon, breast, endocervix, endometrium, and lymphoma. Secondary ovarian involvement by kidney carcinoma occurs very rarely and is usually associated with widespread dissemination. We conducted a review of kidney carcinoma with ovarian metastasis in the literature using the keywords clear cell renal cell carcinoma, papillary renal cell carcinoma, chromophobe renal cell carcinoma collecting duct carcinoma, and ovarian metastasis on Google Scholar and PubMed indices in April 2018, including a case diagnosed in our department. To date, 30 articles presenting 41 cases of kidney carcinoma with ovarian metastasis are reported in the literature. All reviewed cases were analyzed for diagnosis, surgical and systemic therapy, and outcome. Diagnosis may sometimes be challenging, requiring appropriate immunohistochemical markers in difficult cases. A combination of surgery and adjuvant therapy offers significant benefit in disease control or palliation of symptoms. Due to inconsistency in the reported data, further studies are needed to make safe conclusions regarding survival., Competing Interests: The authors have declared that no competing interests exist.

Background/aim: Subcutaneous (s.c.) trastuzumab was introduced in the (neo)adjuvant setting, based on the non-inferiority results and patient preference. In the advanced setting, preliminary safety data have only been reported. We conducted an observational study of s.c. trastuzumab in combination with i.v. pertuzumab and docetaxel in the first-line setting of human epidermal growth factor receptor 2 (HER2)-positive advanced breast cancer., Patients and Methods: In this single-institution study, patients received 600 mg s.c. trastuzumab in combination with 840 mg pertuzumab for the first cycle and 420 mg for the following cycles, and 75-100 mg/m 2 docetaxel, followed by maintenance with s.c. trastuzumab and pertuzumab until disease progression or unacceptable toxicity. Endpoints were efficacy and safety., Results: Forty patients were enrolled. The median number of cycles with docetaxel was six, while the median number of maintenance cycles was 21. With a median follow-up of 37 months, median progression-free survival and overall survival were 24 and 35 months., Conclusion: Subcutaneous trastuzumab in combination with pertuzumab and docetaxel is well tolerated and effective in HER2-positive advanced breast cancer., (Copyright© 2018, International Institute of Anticancer Research (Dr. George J.

Background: Ventriculoperitoneal (VP) shunt is the most common neurosurgical procedure to treat obstructive and communicating hydrocephalus in children and adults but failure are frequent. The knowledge of risk factors related to abdominal shunt failure is useful to avoid complications., Patients and Methods: We analyze retrospectively 86 adults patients affected by obstructive and communicating hydrocephalus operated for VP shunt at our Institution. Statistical analysis was performed in order to correlate shunt malfunctioning with type of abdominal approach (trocar vs mini-laparotomy), perioperative infective status, sex, bowel distention and length of surgical time., Results: Factors statistically significant for surgical shunt revision were the use of trocar (univariate analisys p=0,029 and multivariate p= 0,035) and high infective risk (univariate analisys p=0,028 and multivariate p= 0,038). No statistical significant association was observed between shunt revision and sex, bowel distension and operative length time., Conclusions: To avoid postoperative shunt malfunctions especially in peritoneum the mini-laparotomy is the approach of choice. Surgery must be performed when infective status is healed.

Background: Post-traumatic hydrocephalus (PTH) is one of the main complications of decompressive craniectomy (DC) after traumatic brain injury (TBI). Then, the recognition of risk factors and subsequent prompt diagnosis and treatment of PTH can improve the outcome of these patients. The purpose of this study was to identify factors associated with the development of PTH requiring surgical treatment in patients undergoing DC for TBI., Methods: In this study, we collected the data of 190 patients (149 males and 41 females), who underwent DC for TBI in our Center. Then we analyzed the type of surgical treatment for all patients affected by PTH and the risk factors associated with the development of PTH., Results: Post-traumatic hydrocephalus (PTH) developed in 37 patients out of 130 alive 30 days after DC (28.4%). The development of PTH required ventriculoperitoneal shunt (VPS) in 34 patients out of 37 (91.9%), while, in the remaining 3 patients, cerebrospinal fluid hydrodynamic (CSF) disturbances resolved after urgent cranioplasty and temporary external lumbar drain. Multivariate analysis showed that the presence of interhemispheric hygroma (p < 0.001) and delayed cranioplasty (3 months after DC) (p < 0.001) was significantly associated with the need for a VPS or other surgical procedure for PTH. Finally, among the 130 patients alive after 30 days from DC, PTH was associated with unfavorable outcome as measured by the 6-month Glasgow Outcome Scale score (p < 0.0001)., Conclusions: Our results showed that delayed cranial reconstruction was associated with an increasing rate of PTH after DC. The presence of an interhemispheric hygroma was an independent predictive radiological sign of PTH in decompressed patients for severe TBI.

Objective and Background: Data on intraoperative neurophysiological monitoring (IOM) during surgery of spinal dural arteriovenous fistulas (SDAVFs) are lacking. The purpose of this study was to evaluate the role of IOM during microsurgery for SDAVFs., Materials and Methods: From March 2007 to March 2013, 12 patients had microsurgery with IOM for SDAVFs. The IOM included somatosensory-evoked potentials, motor-evoked potentials (MEPs), and - in selected cases - D-Waves. All patients were evaluated at admission and at follow-up (6, 12, and 24 months) with Aminoff-Logue Disability Scale for Gait-Aminoff-Logue Disability Scale (G-ALS) and Micturition-Aminoff-Logue Disability Scale (M-ALS)., Statistical Analysis Used: Logistic regression was used for detecting the clinical risk factors influencing neurological functions after the treatment., Results: During surgery, we registered the absence of significant modifications of evoked potentials in nine cases (75%), while improvement of MEPs occurred in three cases (25%). No false-negative case was registered, and IOM predicted the absence of new postoperative neurological deficit in all patients. At 24-month follow-up, nine patients improved their overall neurological status, while three patients remained stable. At univariate analysis, Aminoff-Logue Disability Scales for Gait and Micturition (G + M-ALS) score at 24-month follow-up was directly associated with the duration of symptom before the surgery ( P = 0.024), preoperative G-ALS ( P = 0.02), M-ALS ( P = 0.022), and G + M-ALS scores ( P = 0.045), and improvement of IOM after occlusion of the fistula ( P = 0.025)., Conclusions: In our series, no significant worsening of evoked potentials occurred and subsequently the surgical strategy was not changed by IOM. However, no false-negative case was registered, and IOM predicted the absence of new postoperative neurological deficit in all patients. Patients with improvement of IOM parameters after occlusion of the fistula had greater chances of postsurgical improvement at the univariate analysis., Competing Interests: There are no conflicts of interest.

Background/aim: During recent years, a survival advantage was reported for first-line treatment of advanced pancreatic cancer with two new regimens, FOLFIRINOX and gemcitabine/nab-paclitaxel, over gemcitabine monotherapy. Gemcitabine/nab-paclitaxel administration on days 1, 8 and 15 of a 4-week cycle is associated with some practical disadvantages. We adopted a biweekly regimen with the same dose density., Patients and Methods: Patients with Eastern Cooperative Oncology Group performance status 0-2 diagnosed with advanced histologically or cytologically confirmed pancreatic cancer and no prior treatment were included in the study. Study combination included 1.5 g/m 2 gemcitabine and 175 mg/m 2 nab-paclitaxel given every 2 weeks. Survival analysis was performed using the Kaplan-Meier method., Results: Forty-six patients were treated with this regimen. Adverse events were similar to those of the original regimen. Median progression-free and overall survival were 5 and 10 months, respectively., Conclusion: Biweekly gemcitabine/nab-paclitaxel seems to have a similar safety and efficacy profile as the original regimen., (Copyright© 2018, International Institute of Anticancer Research (Dr. George J.
