Introduction: At the Mental Health Centre of Forlì, we have introduced a multidisciplinary working group, a complex psychodiagnostic evaluation, a therapeutic contract and a wide range of evidence based treatments for patients who suffered by severe personality disorders and their families. Specifically we speak about a group psychotherapy based on the principles of W. Bion and on techniques of MBT method (Fonagy and Bateman). Objectives: This study aims to verify the effectiveness of this specific group treatment in reducing symptoms and in increasing retention in treatment measured by some outcomes (drop-out, hospital-admissions, accesses to emergency medical treatments and pharmacotherapy). Methods: During the year 2018 we recruited 15 patients with severe Personality disorders of cluster B (valuated with SCID-II) defined severe by at least one of the criteria of the Region guide lines. We have considered hospital admissions in the previous 12-month period and during the full course of treatment (one year). Results: of the 15, patients were primarily females (9), males were 6, the mean age was 43 yrs, only 5 also had individual not specific psychotherapy. Psychiatric comorbidities are most with Bipolar Disorder (80%). We have noted a drastic reduction of hospital admissions and emergency visits at Emergency Aid and at Mental Health Centre. These outcomes are more substantial for patients who received additionally individual psychotherapy. Conclusions: This approach is effectiveness in reducing drop out, the number and duration of hospital admissions, emergency visits and less number of drug prescription. We think that this is more specific and personalized treatment for these very complicated patients. [ABSTRACT FROM AUTHOR]

Introduction: In the last years, Italian scenario in migratory flows, allowed the realisation of specific regional project. Since 2016 in the Region Emilia Romagna there is a project named START-ER) designed for per RTPI Asylum seekers and beneficiaries of International Protection (RTPI) accomodated in the first reception facilities of the area. Objectives: to increase integration of social and medical assistance by interdisciplinary networking between public and private organisation to improve their health, protection and hospitality. They are subject to post-traumatic vulnerability and have numerous social and health needs. We work in group with migrants according to ethnopsychiatry and ethnopsychoanalysis theories (1,2). Methods: numbers were collected from 21 September 2016 to 31th March 2018 by anagraphic schedule than elaborated by a monitoring system. Diagnosis was made by our diagnostic and statistical manuals of Mental disorders (ICD-9 and DSM-IV). Results: 91 people were helped in the project, of this 72 were male, 19 female and 15 minors. Nationality of 91 people involved in the project most comes from Nigeria. Among patients affected by a mental disorders most diagnosis was mild disorders as Adjustment disfunctioning. Conclusions: through the establishment of multidisciplinary team between public and private workers we promptly intercepted distressed people in the reception facilities where they lived, reducing referral to the Mental Health Centre.

- Abstract
Congenital arhinia and hyporhinia are rare facial anomalies whose knowledge usually comes from case reports. The severity of each case described in literature is variable; it also depends on associated malformations too. Since the newborns are obligate nasal breathers, babies with arhinia or hyporhinia usually have respiratory distress and need airway stabilization. In addition, most of these children present difficulties in feeding and this impairment must be managed early. We describe an unusual case of partial congenital arhinia, the baby did not have other anomalies or any specific complication such as respiratory and feeding issues, so the major problem was the aesthetic and psychological issues for the family. Even if the neonatal course was uncomplicated, a coordinated approach of the pediatrician with the pediatric otolaryngologist, the geneticists and the neurosurgeons was necessary because the management of these malformations is always very complex; due to the lack of reports described in literature, an univocal management and also the best timing and technique for reconstructive surgery are still not defined., Competing Interests: The authors declare no conflicts of interest., (Copyright © 2024 Monica Russo et al.)

- Abstract
Influenza viruses (IV) are single-stranded RNA viruses with a negative-sense genome and have the potential to cause pandemics. While vaccines exist for influenza, their protection is only partial. Additionally, there is only a limited number of approved anti-IV drugs, which are associated to emergence of drug resistance. To address these issues, for years we have focused on the development of small-molecules that can interfere with the heterodimerization of PA and PB1 subunits of the IV RNA-dependent RNA polymerase (RdRP). In this study, starting from a cycloheptathiophene-3-carboxamide compound that we recently identified, we performed iterative cycles of medicinal chemistry optimization that led to the identification of compounds 43 and 45 with activity in the nanomolar range against circulating A and B strains of IV. Mechanistic studies demonstrated the ability of 43 and 45 to interfere with viral RdRP activity by disrupting PA-PB1 subunits heterodimerization and to bind to the PA C-terminal domain through biophysical assays. Most important, ADME studies of 45 also showed an improvement in the pharmacokinetic profile with respect to the starting hit., Competing Interests: Declaration of competing interest The authors declare that they have no known competing financial interests or personal relationships that could have appeared to influence the work reported in this paper., (Copyright © 2024 Elsevier Masson SAS.

- Abstract
In search of novel therapeutic options to treat influenza virus (IV) infections, we previously identified a series of inhibitors that act by disrupting the interactions between the PA and PB1 subunits of the viral RNA polymerase. These compounds showed broad-spectrum antiviral activity against human influenza A and B viruses and a high barrier to the induction of drug resistance in vitro. In this short communication, we investigated the effects of combinations of the PA-PB1 interaction inhibitor 54 with oseltamivir carboxylate (OSC), zanamivir (ZA), favipiravir (FPV), and baloxavir marboxil (BXM) on the inhibition of influenza A and B virus replication in vitro. We observed a synergistic effect of the 54/OSC and 54/ZA combinations and an antagonistic effect when 54 was combined with either FPV or BXM. Moreover, we demonstrated the efficacy of 54 against highly pathogenic avian influenza viruses (HPAIVs) both in cell culture and in the embryonated chicken eggs model. Finally, we observed that 54 enhances OSC protective effect against HPAIV replication in the embryonated eggs model. Our findings represent an advance in the development of alternative therapeutic strategies against both human and avian IV infections., Competing Interests: Declaration of competing interest The authors declare that they have no known competing financial interests or personal relationships that could have appeared to influence the work reported in this paper., (Copyright © 2024.

- Abstract
MicroRNAs (miRNAs) play a crucial role in ovarian cancer (OC) pathogenesis and miRNA processing can be the object of pharmacological intervention. By exploiting our in-house quinolone library, we combined a cell-based screening with medicinal chemistry efforts, ultimately leading to derivative 33 with anti-OC activity against distinct cell lines (GI
50 values 13.52-31.04 μM) and CC50 Wi-38 = 142.9 μM. Compound 33 retained anticancer activity against additional cancer cells and demonstrated a synergistic effect with cisplatin against cisplatin-resistant A2780 cells. Compound 33 bound TRBP by SPR ( KD = 4.09 μM) and thermal shift assays and its activity was TRBP-dependent, leading to modulation of siRNA and miRNA maturation. Derivative 33 exhibited augmented potency against OC cells and a stronger binding affinity for TRBP compared to enoxacin, the sole quinolone identified as a modulator of miRNA maturation. Consequently, 33 represents a promising template for developing novel anti-OC agents with a distinctive mechanism of action., Competing Interests: The authors declare that they have no known competing financial interests or personal relationships that could have appeared to influence the work reported in this paper., (This journal is © The Royal Society of Chemistry.)- Published

- Abstract
Background : Chiari malformation type 1 (CM-1) involves the cerebellar tonsils' descent below the foramen magnum. In Chiari malformation type 1.5 (CM-1.5), both the cerebellar tonsils and the brainstem are herniated. Common symptoms include headaches and cervical pain, often associated with conditions like syringomyelia and hydrocephalus. Surgical treatment is not performed in asymptomatic patients, while the presence of syringomyelia represents an indication for surgery. Methods : This study retrospectively examined pediatric patients with CM-1 and CM-1.5 at Giannina Gaslini Hospital from 2006 to 2020, analyzing demographics, radiological findings, surgical interventions, and outcomes. Results : Out of 211 patients who underwent surgery, 83.9% were diagnosed with CM-1 and 16.1% with CM-1.5. Headaches were prevalent (69%) and cerebellar signs were noted in 29% of patients. Syringomyelia and hydrocephalus were present in 28.4% and 8% of cases, respectively. Intraoperative ultrasonography guided interventions, with 59.8% requiring bony and ligamentous decompression, and 27.1% undergoing duraplasty. Conclusions : The surgical treatment of CM-1/CM-1.5 involves posterior cranial fossa decompression. Choosing between bony decompression alone and its combination with duraplasty has always been controversial in the pediatric population. If we consider as surgical endpoint the restoration of cerebrospinal fluid (CSF) flux, intraoperative ultrasound may be a real-time helpful tool in orienting the surgical strategy, yet refinement with quantitative measures is needed.

- Abstract
Objective: Cerebral cavernous malformations (CCMs) are cerebral vascular lesions that occasionally occur with seizures. We present a retrospective case series from IRCCS Gaslini Children's Hospital, a systematic review, and meta-analysis of the literature with the goal of elucidating the post-surgery seizure outcome in children with CCMs., Methods: a retrospective review of children with cavernous malformation related epilepsy who underwent surgery at Gaslini Children's Hospital from 2005 to 2022 was conducted. We also conducted a comprehensive search on PubMed/MEDLINE and Scopus databases from January 1989 to August 2022. Inclusion criteria were: presence of CCMs-related epilepsy, in under 18 years old subjects with a clear lesion site. Presence of post-surgery seizure outcome and follow-up ≥ 12 months., Results: we identified 30 manuscripts and 223 patients with CCMs-related epilepsy, including 17 patients reported in our series. We identified 85.7% Engel class I subjects. The risk of expected neurological deficits was 3.7%; that of unexpected neurological deficits 2.8%. We found no statistically significant correlations between Engel class and the following factors: site of lesion, type of seizure, drug resistance, duration of disease, type of surgery, presence of multiple CCMs. However, we found some interesting trends: longer disease duration and drug resistance seem to be more frequent in subjects in Engel class II, III and IV; multiple cavernomas would not seem to influence seizure outcome., Conclusions: epilepsy surgery in children with CCMs is a safe and successful treatment option. Further studies are necessary to define the impact of clinical features on seizure prognosis., (© 2024.

- Abstract
We report the case of a preterm of 27 weeks of gestation who developed posthemorrhagic ventricular dilatation associated to a complete thrombosis of the superior sagittal sinus, for its peculiar interest in clarifying the physiology of the cerebrospinal fluid (CSF) dynamics. The exact CSF volume that must be removed to improve cerebral hemodynamics and outcomes in infants with posthemorrhagic ventricular dilatation is unknown. According to Volpe's studies, a volume of 10 to 15 mL/kg/die of body weight is commonly chosen. The subject we report needed an excessive CSF drainage (up to 32 mL/kg/d), in presence of a functioning external ventricular drain. We review the literature on the topic, and we postulate that the superior sagittal sinus may play an active role in the CSF dynamics of the immature brain (as it happens for the adult brain)., Competing Interests: None declared., (Thieme.

- Abstract
Among the eight different triazolopyrimidine isomers existing in nature, 1,2,4-triazolo[1,5- a ]pyrimidine (TZP) is one of the most studied and used isomers in medicinal chemistry. For some years, our group has been involved in developing regioselective one-pot procedures for the synthesis of 2-amino-7-aryl-5-methyl- and 2-amino-5-aryl-7-methyl-TZPs of interest in the preparation of antiviral agents. In this work, taking advantage of a Biginelli-like multicomponent reaction (MCR), we report the identification of finely tunable conditions to regioselectively synthesize C-6 ester-substituted amino-TZP analogues, both in dihydro and oxidized forms. Indeed, the use of mild acidic conditions is strongly directed toward the regioselective synthesis of 5-aryl-7-methyl C-6-substituted TZP analogues, while the use of neutral ionic liquids shifted the regioselectivity towards 7-aryl-5-methyl derivatives. In addition, the novel synthesized scaffolds were functionalized at the C-2 position and evaluated for their antiviral activity against RNA viruses (influenza virus, flaviviruses, and SARS-CoV-2). Compounds 25 and 26 emerged as promising anti-flavivirus agents, showing activity in the low micromolar range.

- Abstract
Background: In the last years, numerous studies evaluated different tools for the diagnosis of positional plagiocephaly (PP). The purpose of this study was to evaluate ultrasonography (US) as a first line screening test of lambdoid sutural patency in child with PP and to compare our results with the literature., Methods: All consecutive patients who referred to our Institute from January 2016 to October 2017 with the suspicion of PP, were included in the study and performed US examination of the lambdoid sutures. A 3-6-month clinical follow-up was performed by a pediatric neurosurgeon or a pediatrician to confirm the diagnosis of PP., Results: Thirty-five children performed US examination and in all cases the diagnosis of PP was confirmed. No cases of anticipated suture fusion were examined during this period. The concordance between US findings and clinical exam follow-up was 100%., Conclusions: Ultrasonography of the lambdoid sutures represents an ideal first-line screening test and reliable alternative to other diagnostic techniques for lambdoid sutural patency in child with PP, being radiation free, fast and cheap.

- Abstract
Various strategies have been proposed for the treatment of gelastic seizures due to hypothalamic hamartomas (HH), advancing from surgical removal techniques toward functional disconnection strategies. One of the most recent procedure is the Magnetic Resonance guided Laser Interstitial Thermal Therapy (MRg-LITT), which has progressively proved to be a safe and effective technique for hamartomas ablation. In this paper, the authors' preliminary experience with the first two patients treated with this technique in Italy is presented, in order to underline the feasibility of a pure non robotized frameless technique (FS MRg-LITT) while confirming the procedure effectiveness on seizure control. Patients undergoing FS MRg-LITT for the treatment of HH related gelastic seizures since January 2020 were included. A two steps procedure was performed by using the neuronavigation system to define the entry point, the trajectories and to assess the accuracy. Visualase Laser Ablation System was then used for the MR guided ablation of the HH. A multidisciplinary (neurosurgeons, epileptologist, neuroradiologist) institutional board evaluated the patients both in the perioperative period and during follow-up. A total number of 2 pediatric patients were described. The mean operative time resulted to be 6 hours while the mean accuracy was 0.4 mm. No perioperative complications were reported. The mean length of stay was 4 days. Lastly, at 1-year follow-up both patients resulted to be seizure free and endocrinological functions were preserved. FS MRg-LITT for the treatment of HH-related epilepsy could represent an effective technique, being able to guarantee adequate level of accuracy and potentially extending the accessibility of MRg-LITT by lowering its costs and simplifying the overall procedure.

- Abstract
Synthetic lethality (SL) is an innovative strategy in targeted anticancer therapy that exploits tumor genetic vulnerabilities. This topic has come to the forefront in recent years, as witnessed by the increased number of publications since 2007. The first proof of concept for the effectiveness of SL was provided by the approval of poly(ADP-ribose)polymerase inhibitors, which exploit a SL interaction in BRCA-deficient cells, although their use is limited by resistance. Searching for additional SL interactions involving BRCA mutations, the DNA polymerase theta (POLθ) emerged as an exciting target. This review summarizes, for the first time, the POLθ polymerase and helicase inhibitors reported to date. Compounds are described focusing on chemical structure and biological activity. With the aim to enable further drug discovery efforts in interrogating POLθ as a target, we propose a plausible pharmacophore model for POLθ-pol inhibitors and provide a structural analysis of the known POLθ ligand binding sites.

- Abstract
The cellular level of TDP-43 (also known as TARDBP) is tightly regulated; increases or decreases in TDP-43 have deleterious effects in cells. The predominant mechanism responsible for the regulation of the level of TDP-43 is an autoregulatory negative feedback loop. In this study, we identified an in vivo cause-effect relationship between Tardbp gene promoter methylation and specific histone modification and the TDP-43 level in tissues of mice at two different ages. Furthermore, epigenetic control was observed in mouse and human cultured cell lines. In amyotrophic lateral sclerosis, the formation of TDP-43-containing brain inclusions removes functional protein from the system. This phenomenon is continuous but compensated by newly synthesized protein. The balance between sequestration and new synthesis might become critical with ageing, if accompanied by an epigenetic modification-regulated decrease in newly synthesized TDP-43. Sequestration by aggregates would then decrease the amount of functional TDP-43 to a level lower than those needed by the cell and thereby trigger the onset of symptoms., Competing Interests: Competing interests The authors declare no competing or financial interests., (© 2022.

- Abstract
The role of MR Arterial-Spin-Labeling Cerebral Blood Flow maps (ASL-CBF) in the assessment of pediatric focal epilepsy is still debated. We aim to compare the Seizure Onset Zone (SOZ) detection rate of three methods of evaluation of ASL-CBF: 1) qualitative visual (qCBF), 2) z-score voxel-based quantitative analysis of index of asymmetry (AI-CBF), and 3) z-score voxel-based cluster analysis of the quantitative difference of patient’s CBF from the normative data of an age-matched healthy population (cCBF). Interictal ASL-CBF were acquired in 65 pediatric patients with focal epilepsy: 26 with focal brain lesions and 39 with a normal MRI. All hypoperfusion areas visible in at least 3 contiguous images of qCBF analysis were identified. In the quantitative evaluations, clusters with a significant z-score AI-CBF ≤ −1.64 and areas with a z-score cCBF ≤ −1.64 were considered potentially related to the SOZ. These areas were compared with the SOZ defined by the anatomo-electro-clinical data. In patients with a positive MRI, SOZ was correctly identified in 27% of patients using qCBF, 73% using AI-CBF, and 77% using cCBF. In negative MRI patients, SOZ was identified in 18% of patients using qCBF, in 46% using AI-CBF, and in 64% using cCBF (p < 0.001). Quantitative analyses of ASL-CBF maps increase the detection rate of SOZ compared to the qualitative method, principally in negative MRI patients.

- Abstract
Background: Since external ventricular drainage (EVD) related infections are usually due to skin flora, an extradural intra/extra-cranial accessory device, developed for pediatric patients under three years of age undergoing EVD positioning, is described. The aim of this paper is to provide technical description of this device, underlining the possibility to reduce infective risk and to prevent EVD dislocation., Methods: Patients undergoing A-D device EVD placement between 1990 and 2017 at authors' institution were retrospectively considered. The device was made of a fully MRI-compatible inert material (Ketron-Peek-1000), composed of two pieces securely fixable to the skull, bridging the catheter directly from the epidural space to the extracranial space without letting it come in contact with the skin., Results: A total number of 350 patients were considered. The mean age was 1.4 years, being the youngest patient a newborn of 25 weeks of gestational age. Mean time of EVD maintenance was 45 days, ranging from 21 to 81 days. 2 cases (0.6%) of EVD related infections were reported, while, pull-out of the ventricular catheter occurred in 3 cases (0.9%). No cases of bone fractures related to the clamp effect provided by A-D device were reported in the series CONCLUSIONS: This device could represent a safe and feasible option to reduce EVD related infections and catheter pull-out in pediatric patients. The encouraging results could strength the aim of the device to allow safer and longer length of CSF drainage. Moreover, the fully MRI-compatible nature and its non-magnetic properties allow to use it with neuronavigation systems., (Copyright © 2021 Elsevier B.V. All rights reserved.)

- Abstract
Magnetic resonance-guided laser interstitial thermal therapy (MR-gLiTT) is a novel minimally invasive treatment approach for drug-resistant focal epilepsy and brain tumors. Using thermal ablation induced by a laser diode implanted intracranially in a stereotactic manner, the technique is highly effective and safe, reducing the risk associated with more traditional open surgical approaches that could lead to increased neurological morbidity. Indications for MR-gLiTT in pediatric epilepsy surgery include hypothalamic hamartoma, tuberous sclerosis complex, cavernoma-related epilepsy, SEEG-guided seizure onset zone ablation, corpus callosotomy, periventricular nodular heterotopia, mesial temporal lobe epilepsy, and insular epilepsy. We review the available literature on the topic and present our series of patients with drug-resistant epilepsy treated by MR-gLiTT. Our experience, represented by six cases of hypothalamic hamartomas, one case of tuberous sclerosis, and one case of dysembryoplastic neuroepithelial tumor, helps to confirm that MR-gLiTT is a highly safe and effective procedure for several epilepsy conditions in children., Competing Interests: The authors declare that the research was conducted in the absence of any commercial or financial relationships that could be construed as a potential conflict of interest., (Copyright © 2021 Consales, Cognolato, Pacetti, Mancardi, Tortora, Di Perna, Piatelli and Nobili.)

- Abstract
The role of muscle biopsy in the diagnostic workup of floppy infants is controversial. Muscle sampling is invasive, and often, results are not specific. The rapid expansion of genetic approach has made the muscle histopathology analysis less crucial. This study aims to assess the role and efficacy of muscle histopathology in the diagnostic algorithm of hypotonia in early infancy through a retrospective analysis of 197 infants who underwent muscle biopsy in their first 18 months of life. Data analysis revealed that 92/197 (46.7%) of muscle biopsies were non-specific (80) or normal (12), not allowing a specific diagnosis. In 41/197 (20.8%) cases, biopsy suggested a metabolic or mitochondrial myopathy, while in 23/197 cases (11.7%), we found evidence of muscular dystrophy. In 19/197 cases (9.7%), histopathology characteristics of a congenital myopathy were reported. In 22/197 cases (11.7%), the histopathological study indicated presence of a neurogenic damage. Overall, 46 diagnoses were then achieved by oriented genetic tests. Muscle biopsy results were consistent with genetic results in 90% of cases. Diagnostic algorithms for the diagnosis of a floppy infant are largely missing. Muscle biopsy alone can lead to a diagnosis, help the clinician in the choice of a genetic test, or even modify a diagnosis made previously., Competing Interests: The authors declare that the research was conducted in the absence of any commercial or financial relationships that could be construed as a potential conflict of interest., (Copyright © 2021 Veneruso, Fiorillo, Broda, Baratto, Traverso, Donati, Savasta, Falsaperla, Mancardi, Pedemonte, Panicucci, Piatelli, Pacetti, Moscatelli, Ramenghi, Nobili, Minetti and Bruno.)

- Abstract
The management of drug-resistant patients with focal epilepsy is often challenging. Surgery is recognised as a useful and effective treatment option. The identification of the epileptogenic zone relies on the integration of clinical, neurophysiological, and neuroimaging findings. The role of non-invasive functional neuroimaging techniques has been reported to add diagnostic accuracy to first-line evaluations, avoiding invasive presurgical examinations in selected cases. In this view, we report the case of a 16-year-old male suffering from drug-resistant focal epilepsy with episodes rarely evolving to a bilateral tonic-clonic seizure. Conventional 1.5T and 3T MRI were considered uninformative. Based on electro-clinical data, focal cortical dysplasia was suspected. The epileptogenic zone was identified with the integration of further non-invasive functional neuroimaging techniques ([18F]-fluorodeoxyglucose positron emission tomography and arterial spin labelling), where electrical source imaging played the main role. All techniques pointed towards a cortical region, where a 7T brain MRI identified a signal alteration consistent with focal cortical dysplasia. A tailored resection of the lesion located in the inferior frontal sulcus was performed, guided by intraoperative electrocorticography (strip and depth electrodes). Postoperative seizure freedom was achieved. The histopathology confirmed the suspicion of focal cortical dysplasia type IIa. With this case report, we highlight the importance of a multimodal approach in the presurgical evaluation of candidates for epilepsy surgery, which, in selected cases, may allow invasive procedures, such as stereo-EEG, to be avoided in the investigation of the epileptogenic zone. Moreover, we underline the pivotal role of EEG source imaging, especially when focal cortical dysplasia is suspected.

- Abstract
Hemispheric surgery is an effective and cost-effective option for hemispheric epilepsy. Data specifically focusing on very early infancy are scant. In our study, we report the results of hemispheric surgery in children under three years of age, along with clinical, neuroradiological and EEG features, from two Italian epilepsy surgery centres. After reviewing our epilepsy surgery databases (2008-2018), we identified 14 patients (seven males) submitted to hemispheric surgery, under three years (range: 2-29 months), with a follow-up of at least 12 months. No deaths occurred, and surgical complications were observed in 3/17 procedures. At final follow-up visit (mean: 30.8 months; range: 12-90), 10/14 patients (71.4%) achieved Engel Class I (eight Class 1A, one Class 1B, and one Class 1C). Antiepileptic drugs were completely discontinued in three and reduced in eight, thus a significant decrease in drug regimen after surgery was achieved in 11/14 patients (78.6%). Before surgery, severe developmental delay was present in 10 patients, moderate in two and mild in two. At the last follow-up visit, the degree of developmental delay changed from severe to moderate in five patients, remained unchanged in six cases (four severe and two moderate), and changed from mild to moderate in two following surgery. In many cases, hemispheric surgery in children under three years is effective in achieving seizure freedom or reducing seizure frequency, with the possibility of simplifying complex drug regimens. Moreover, it appears to be a safe and well tolerated procedure, leading to improvement in cognition and posture.

- Abstract
Cohort study. This follow-up study (from 1975 to 2016) was aimed to estimate the mortality risk for suicide in a cohort of patients presenting to a public treatment centre for addiction (SERD) with Alcohol Use Disorder (AUD), Heroin Use Disorder - HUD or Cocaine Use Disorder (CUD), also relating to their access to a Mental Heath Service. Crude Mortality Rates for suicide were higher for patients with AUDs, for men and subjects 45-64 years old. Hanging was the main cause of suicide death. We highlight an increase in mortality in the period 2009-2012, which coincides with the economic recession, and in the year of first contact with a SERD. The Standardized Mortality Ratios (SMRs) were 4.9, higher among females than males. From the multivariate analysis, a higher risk for patients that were separated or divorced was observed. The results of our study provide some guidance on the features of subjects at greatest risk of death from suicide, which may be useful in reducing and preventing suicide and gaining a better clinical management of patients with SUDs., (Copyright © 2020.

- Abstract
Objective: To assess seizure and cognitive outcomes and their predictors in children (<16 years at surgery) and adults undergoing temporal lobe epilepsy (TLE) surgery in eight Italian centers., Methods: This is a retrospective multicenter study. We performed a descriptive analysis and subsequently carried out multivariable mixed-effect models corrected for multiple comparisons., Results: We analyzed data from 511 patients (114 children) and observed significant differences in several clinical features between adults and children. The possibility of achieving Engel class IA outcome and discontinuing antiepileptic drugs (AEDs) at last follow-up (FU) was significantly higher in children (P = .006 and < .0001). However, percentages of children and adults in Engel class I at last FU (mean ± SD, 45.9 ± 17 months in children; 45.9 ± 20.6 months in adults) did not differ significantly. We identified different predictors of seizure outcome in children vs adults and at short- vs long-term FU. The only variables consistently associated with class I outcome over time were postoperative electroencephalography (EEG) in adults (abnormal, improved,odds ratio [OR] = 0.414, P = .023, Q = 0.046 vs normal, at 2-year FU and abnormal, improved, OR = 0.301, P = .001, Q = 0.002 vs normal, at last FU) and the completeness of resection of temporal magnetic resonance (MR) abnormalities other than hippocampal sclerosis in children (OR = 7.93, P = .001, Q = 0.003, at 2-year FU and OR = 45.03, P < .0001, Q < 0.0001, at last FU). Cognitive outcome was best predicted by preoperative performances in either age group., Significance: Clinical differences between adult and pediatric patients undergoing TLE surgery are reflected in differences in long-term outcomes and predictors of failures. Children are more likely to achieve sustained seizure freedom and withdraw AEDs after TLE surgery. Earlier referral should be encouraged as it can improve surgical outcome., (© 2020 International League Against Epilepsy.)

- Abstract
Purpose: Arachnoid cysts may present with symptoms deriving from cyst rupture, usually causing intracystic hemorrhage and subdural hematoma or hygroma. Rupture is usually caused by minor trauma, spontaneous rupture is an exceptional event, and 57 cases have been described in literature. We here present and discuss the largest series of spontaneously ruptured middle fossa arachnoid cysts in order to investigate clinical presentation and best treatment available., Methods: We report a retrospective series of 17 pediatric patients surgically treated for middle fossa arachnoid cyst with signs of cyst rupture without a history of trauma in the previous 90 days. We describe clinical presentation, treatment, and outcome at follow-up discussing our results with a literature review including all reported cases of spontaneous rupture of middle fossa arachnoid cysts., Results: In our experience patients most frequently presented with subdural hygroma, in literature, a chronic hematoma was most frequently reported. Headache is the most reported symptom at presentation. Neurological deficits and consciousness alterations are rare. Surgical treatment may resolve brain compression only or reduce rupture recurrence risk. Conservative treatment has also been proposed. Different treatments are reported and discussed focusing on indications, contraindications, risks, and expected benefits., Conclusion: We propose, when safely possible, microsurgical cyst fenestration in skull base cisterns as the treatment of choice for these patients as long as it addresses both immediate decompression and risk of rupture recurrence. We report good outcomes and low incidence of complications from our series with a mean postoperative follow-up of 30 months.

- Abstract
Large-scale longitudinal studies show that specific borderline personality disorder (BPD) symptoms are more likely to remit over time, suggesting that clinical features of BPD may vary between younger patients and older ones. The objective of the present report is to provide a direct comparison between younger (age 18-25 years; n = 44) and older (age 40-59 years; n = 49) BPD patients on the nine DSM-4 BPD criteria (self-harm, emotional dysregulation, impulsiveness, and work and social functioning). Younger and older patients reported similar levels of impulsiveness, emotional dysregulation, and work and social functional impairment. Younger adults were more likely to show anger and self-damaging behaviors compared with older patients, which in turn were more likely to endorse chronic emptiness. In conclusion, older patients with BPD are still impaired in impulsiveness, emotional regulation, and social functioning; treatments for older BPD population should be long term and focused on emotion dysregulation and impulsive behaviors.

- Abstract
Background: Listeria monocytogenes is a Gram-positive bacteria transmitted to human by animal stools, contaminated water and food. In children, Listeria monocytogenes typically affects newborns and immunocompromised patients often leading to invasive syndromes including sepsis, brain abscesses, meningitis, meningoencephalitis and rhombencephalitis. In healthy and immunocompetent children, Listeria meningitis is rare, but can progress rapidly and may be associated with severe complications (hydrocephalus, ventriculitis, cranial nerves palsy and cerebrospinal abscesses) and high mortality rate., Case Presentation: We describe a very uncommon case of meningoencephalitis due to Listeria monocytogenes in a 11-month-old immunocompetent girl. Cerebrospinal fluid (CSF) culture was positive on the second day. Antibiotic therapy was promptly started but the disease was complicated by neurological deterioration and decompensated hydrocephalus. The child required a very demanding pediatric and neurosurgical management and was discharged after 40 days without major sequelae., Conclusion: Listeria is difficult to isolate and it is not susceptible to first-line treatment for bacterial meningitis with extended-spectrum cephalosporins. Early recognition is therefore crucial for a positive outcome. Pediatricians have to perform close clinical monitoring of these children and be aware of possible complications. A review of all cases of Listeria meningitis complicated by hydrocephalus in healthy children has been performed, to provide an overview on clinical features, treatment options and outcome.

- Abstract
Background: Over the last decades, significant advancements have been achieved in the treatment of pediatric brain tumors as a result of radiation therapy (RT). With the increasing diffusion of this treatment, iatrogenic damage to cerebrovascular tissues contouring the radiation target volume has become the subject of debate, especially radiation-induced moyamoya syndrome (RIMS)., Methods: A systematic literature search was performed on the association between moyamoya vasculopathy and cranial irradiation in children. Large case series of patients with moyamoya were analyzed and clinicoradiologic data were collected reviewing pediatric patients treated with RT for primary brain tumors at our institution., Results: The risk of developing RIMS is higher in younger children, in patients with optic pathway glioma, and in those receiving higher radiation doses. Headache is the most common presenting symptom and cerebral infarction is frequent. The preferred surgical techniques were pial synangiosis and encephaloduroarteriosynangiosis. In our case series, surgical revascularization led to neovascularization, with clinical improvement or stability in all patients. Medical therapy did not significantly affect the clinical course., Conclusions: Pediatric patients receiving involved field RT for the treatment of brain tumors have an increased risk of developing RIMS. Prompt diagnosis and early surgical revascularization play a pivotal role in decreasing the clinical impact of this complication. The use of new techniques, such as the intensity-modulated RT, and the increasing dose saving for the organs at risk, are essential to prevent iatrogenic vasculopathy. The combination of appropriate medical therapy and surgery will improve patient management and clinical outcome., (Copyright © 2019 Elsevier Inc. All rights reserved.)

- Abstract
Background: Bilateral lambdoid and posterior sagittal synostosis is a rarely encountered multisutural craniosynostosis accounting for 0.3%-0.7% of all craniosynostoses. It has been named "Mercedes-Benz Syndrome" (MBS) because of the bone ridges that resemble the Mercedes-Benz logo. The typical head shape is usually described as anterior turricephaly combined with mild brachycephaly. We describe a case of pure MBS without involvement of other sutures. Since we believe that MBS is a different pathology when other sutures are involved, we will discuss our case with a review of the literature, including all reported cases of bilateral lambdoid and posterior sagittal synostosis with no other sutures involved but sagittal and bilateral lambdoid., Case Description: A 3-month-old female baby came to our attention because of a turrycephalic appearance of the head. Findings of the neurologic examination were unremarkable. Computed tomography scan showed premature fusion of posterior third of sagittal suture and bilateral lambdoid suture. Magnetic resonance imaging did not show relevant intracranial abnormalities. She underwent sagittal decompression extended posteriorly below the lambdoid suture combined with biparietal decompression to obtain expansion of both parieto-frontal bones and posterior fossa. Post-operative course was uneventful. Follow-up at 3 months showed a good aesthetic result, and results of the neurologic examination were unremarkable., Conclusions: Pure MBS is a rare condition that unlike other multisutural complex craniosynostosis is rarely associated with genetic syndromes, has a low rate of associated intracranial anomalies, and has less need for more skull-remodeling surgery. The choice of the most suitable surgical procedure must be tailored on the patient, considering preoperative head appearance and eventually associated anomalies., (Copyright © 2019 Elsevier Inc.

- Abstract
Background: Nontraumatic atlantoaxial subluxation, also known as Grisel syndrome, is a rare disease that usually affects children. The typical presentation is torticollis in patients with a history of surgical operations or airway infections., Methods: We describe 5 patients with Grisel syndrome, referring to medical care for a torticollis, a few weeks after an airway infection, with no trauma associated. Radiologic confirmation of the diagnosis, with computed tomography and magnetic resonance imaging studies, was carried out., Results: The patients were treated with external immobilization for 3 months, followed by surgical fixation in the case of recurrence after collar removal or inveterate subluxation. We performed a review of the literature to define the best management of this disease., Conclusions: Management of Grisel syndrome depends on the degree of subluxation basing on the Fielding and Hawkins classification. The initial nonsurgical management consists of close reduction and immobilization. Surgical fixation is indicated in cases of conservative treatment failure., (Copyright © 2019 Elsevier Inc.

- Abstract
Background: Dermoid and epidermoid cysts are among the most frequent lesions of the scalp in the pediatric population. Optimal management of a suspected dermoid or epidermoid cyst in children is debated: Some authors advocate conservative management on the basis of the benign histology of these entities, while others prefer surgical excision., Objective: Our objective is to demonstrate that excision of dermoid and epidermoid cysts is a safe procedure and that early surgery is effective in preventing potential complications related to cyst growth., Methods: We retrospectively collected data on patients who underwent surgery for excision of proven dermoid or epidermoid cysts between January 2006 and October 2017., Results: In 234 patients, 237 cysts were excised. Mean age at presentation was 26.99 ± 32.7 months; 48.7% of patients were operated on between 1 and 3 years of age, and 32.9% were younger than 1 year of age. Cysts were more frequently located in the frontal bone than in occipital and supraorbital regions. In 36.28% of cases there was no significant cranial impingement, while 21.94% of the cysts eroded through a partial thickness of the cranium, 12.23% were in the full thickness of the skull, and 0.84% had epidural extension. We identified 22 intradiploic cysts. Statistical analysis demonstrated significant association between frontal and pterional localization and bone erosion. Neither major complications nor cyst recurrence were observed., Conclusions: Excision of dermoid and epidermoid cysts is a safe procedure for neurosurgeons dealing with this disease, even in young patients. Early resection is recommended due to the potential adverse effects that may occur if these cysts are left untreated., (Copyright © 2018 Elsevier Inc. All rights reserved.)

- Abstract
Introduction: Moyamoya disease is a steno-occlusive cerebrovascular disease of unknown etiology involving the terminal portion of the internal carotid artery and the proximal portions of the anterior and middle cerebral arteries with associated collateral vascular network. When the vascular pattern is associated with a particular condition (e.g., Type 1 neurofibromatosis, Down syndrome), it is defined as moyamoya syndrome (MMS) (or quasi-moyamoya). Among different indirect bypass techniques used to prevent ischemic injury by increasing collateral blood flow to hypoperfused areas of the cortex, multiple burr holes technique is an easy and diffuse indirect revascularization approach in the treatment of moyamoya., Discussion: While the effectiveness in patients with moyamoya disease was demonstrated, its role in MMS remains uncertain. In this study, we describe surgical and diagnostic implications in three pediatric cases of moyamoya sydrome unsuccessfully treated with multiple cranial burr hole technique. A critical review of the literature about the use of the surgical indirect revascularization techniques in pediatric patients was also reported., Competing Interests: There are no conflicts of interest.

- Abstract
Background and Purpose: Indirect revascularization surgery is an effective treatment in children with Moyamoya vasculopathy. In the present study, we hypothesized that DSC-PWI may reliably assess the evolution of CBF-related parameters after revascularization surgery, monitoring the outcome of surgical pediatric patients with Moyamoya vasculopathy. Thus, we aimed to evaluate differences in DSC-PWI parameters, including the hemodynamic stress distribution, in surgical and nonsurgical children with Moyamoya vasculopathy and to correlate them with long-term postoperative outcome., Materials and Methods: Pre- and postoperative DSC parameters of 28 patients (16 females; mean age, 5.5 ± 4.8 years) treated with indirect revascularization were compared with those obtained at 2 time points in 10 nonsurgical patients (6 females; mean age, 6.9 ± 4.7 years). We calculated 4 normalized CBF-related parameters and their percentage variance: mean normalized CBF of the MCA territory, mean normalized CBF of the proximal MCA territory, mean normalized CBF of cortical the MCA territory, and hemodynamic stress distribution. The relationship between perfusion parameters and postoperative outcomes (poor, fair, good, excellent) was explored using 1-way analysis of covariance ( P < .05)., Results: A significant decrease of the mean normalized CBF of the proximal MCA territory and hemodynamic stress distribution and an increase of the mean normalized CBF of the cortical MCA territory were observed after revascularization surgery ( P < .001). No variations were observed in nonsurgical children. Postoperative hemodynamic stress distribution and its percentage change were significantly different in outcome groups ( P < .001)., Conclusions: DSC-PWI indices show postoperative hemodynamic changes that correlate with clinical outcome after revascularization surgery in children with Moyamoya disease., (© 2018 by American Journal of Neuroradiology.)

- Abstract
Background: Iatrogenic pseudoaneurysm of the superficial temporal artery after surgery for craniosynostosis is a complication that has never been described in the pertinent literature. Although reported for other types of surgeries, no case has been described in the pediatric population., Case Description: We report on a case of pseudoaneurysm of the superficial temporal artery that occurred 9 days after corrective surgery for scaphocephaly. We also describe the management of this complication., Conclusion: Pseudoaneurysm is an exceptional complication in surgery for craniosynostosis, but it should be considered in case of swelling in the temporal region., (Copyright © 2017 Elsevier Inc.

- Abstract
Background: Congenital spinal lipomas are closed spinal dysraphisms belonging to the neural tube defects (NTDs) group. They include a broad spectrum of lesions ranging from simple lipomas of the filum terminale to complex malformations. On histological evaluation, various tissue components of ectodermal, mesodermal or endodermal origin are found within the lipomas, with prevalence for nerves and striated muscle and, more rarely, cartilage and bone. Overall, rib malformations have been occasionally observed in patients with NTDs and in NTD mouse models. However, an ectopic rib arising within the spinal lipoma and articulating with the iliac crest has not been reported in either animal models or in humans., Cases: We describe four patients affected by lipomyeloschisis or lipomyelomeningocele, with an unusual fibrocartilaginous protuberance arising within the lipoma and connecting to one iliac crest, strongly resembling an ectopic rib. Histological evaluation confirmed the presence of cartilaginous tissue., Conclusion: We expand the clinical spectrum of fibrocartilaginous anomalies associated with spinal lipoma, suggesting the presence of an ectopic rib as a new possible phenotype in NTDs. A careful analysis by neuroradiologists and pathologists should be performed in spinal lipomas to assess the presence of an ectopic rib or other uncommon developmental anomalies. Furthermore, molecular studies are required to detect the genetic cause of this unusual phenotype.

- Abstract
Background: A randomised study was conducted on the number of attempts made during the conventional endotracheal intubation of a mannequin using two polyvinyl (PVC) tracheal tubes, apparently similar but from different manufactures: INTERSURGICAL (IS; Intersurgical S.L., Madrid, Spain) and Mallinckrodt (ML; Mallinkrodt Medical S.A., Madrid, Spain)., Methods: A total of 26 anaesthesiologists, in randomly established order (generated by Epidat 3.1) intubated a mannequin twice using a different tube each time. The tubes were masked by painting them to prevent recognition. The main outcome of the study was to compare the number of attempts needed to complete the manoeuvre for each tube. Data on intubation time and failed intubations were also collected., Results: The number of attempts with the ML tube was significantly lower than with the IS tube. Intubation was completed on the first attempt with the ML tube in 93.3% of cases, while using the IS tube the percentage fell to 30.8% (Fisher exact test, P<.001). The time required to complete the manoeuvre was greater with the IS tube (median 10.8seconds, interquartile range 6-22) than with the ML tube (median 4.4seconds, interquartile range 3.5 to 6.3)., Conclusions: The PVC tube from the ML manufacturer was superior when compared with the IS, the latter was also associated with a larger number of attempts to complete intubation using a conventional Macintosh blade., (Copyright © 2015 Sociedad Española de Anestesiología, Reanimación y Terapéutica del Dolor.
