Humanisation and health needs in children: present or future?

AIM: For a few years, teledentistry has been an emerging innovative strategy with potential in the field of paediatric dentistry. There are still few studies in this regard, so further research is needed to verify and ensure that teledentistry is not only an accessible mode of communication, but above all effective and evidence-based. This study aimed to use a preliminary telematic approach to promote the compliance of patients in the developmental age during the first dental visit. MATERIALS: Two hundred patients were selected according to the eligibility criteria, and distributed in two groups: a study group with the preliminary telematic approach (ATP) before the first visit and a control group with traditional first visit without ATP. Through an ordinal semi-proportional regression model, the degrees of collaboration between the study and control groups were compared, correcting the estimate for age groups, the presence of systemic pathologies, disorders of cognition, attention and learning, degree of anxiety and previous medical-dental experiences. CONCLUSION: The preliminary telematic approach could be useful as a support to the traditional paediatric dental visit, to promote better management and fidelity of the patient, reducing anxiety and increasing collaboration during the first visit.

Galaxy clusters enveloped by vast volumes of relativistic electrons.

The central regions of galaxy clusters are permeated by magnetic fields and filled with relativistic electrons1. When clusters merge, the magnetic fields are amplified and relativistic electrons are re-accelerated by turbulence in the intracluster medium2,3. These electrons reach energies of 1-10 GeV and, in the presence of magnetic fields, produce diffuse radio halos4 that typically cover an area of around 1 Mpc2. Here we report observations of four clusters whose radio halos are embedded in much more extended, diffuse radio emission, filling a volume 30 times larger than that of radio halos. The emissivity in these larger features is about 20 times lower than the emissivity in radio halos. We conclude that relativistic electrons and magnetic fields extend far beyond radio halos, and that the physical conditions in the outer regions of the clusters are quite different from those in the radio halos.

Lacosamide in monotherapy in BTRE (brain tumor-related epilepsy): results from an Italian multicenter retrospective study.

PURPOSE: Lacosamide (LCM) is a third-generation anti-seizure medication (ASM) approved for focal onset epilepsy in patients aged ≥ 4.378 Previous studies have reported an efficacy of LCM as add-on treatment in brain tumor-related epilepsy (BTRE). To date, there are no studies in the literature focusing on lacosamide used in monotherapy to treat BTRE. In our retrospective study we investigated efficacy and tolerability of LCM in monotherapy in a multicenter national cohort of primary brain tumor patients. METHODS: We collected from 12 Italian Centers 132 patients with primary brain tumors who were treated with LCM in monotherapy. For each patient we evaluated seizure freedom at 3 and 6 months (primary endpoints), side effects and drop-out rate (secondary endpoints). RESULTS: Overall, LCM led to seizure freedom in 64.4% of patients at 3 months and 55% at 6 months. Patients who used two or more ASMs before LCM had a worse seizure control than patients in monotherapy with LCM as first choice. In 14 patients, we observed seizure control despite tumor progression on magnetic resonance (MRI). Multivariate analysis showed that gross-total resection at diagnosis was significantly associated with higher seizure freedom rate at 6 months. Side effects were mainly mild (grade 1-2 according to CTCAE classification) and drop-out rate was low (1.5%). Main side effects were dizziness and somnolence. CONCLUSIONS: This is the first study showing a good efficacy and tolerability of LCM when used in monotherapy in BTRE. Further prospective studies are needed to confirm these preliminary data, investigating also quality of life and neurocognitive functions.

Impact of lockdown on children's lifestyle and their collaboration during dental sessions.

AIM: To analyse lifestyle of Italian families during lockdown, evaluating its possible impact on the collaboration of children with the paediatric dentist and associated predictive factors. MATERIALS AND METHODS: Only patients aged between 3 and 16 years, who had started treatment before the lockdown and had spent this periodwith both parents were included in the study. The interviews were carried out using an anonymous questionnaire that assessed school and play activities, the type of diet, the time dedicated to home oral hygiene and the activities carried out with parents. Parents' work situation during lockdown was included to correlate it with time spent at home. The Frankl Behavior Rating Scale was used to determine the degree of cooperation during dental sessions pre- and post-lockdown. Chi-square test and Fisher's Exact tests were used to identify statistical associations of improvement with each categorical variable. Student's t-test was used to highlight the differences in mean values of continuous variables between subjects considered more cooperative and unimproved subjects. Hosmer-Lemeshow test was used to assess the goodness-of-fit of the model. Assumption of linearity of independent variables and log-odds were assessed by Box-Tidwell transformation. Final selection was carried out using the Akaike criterion and all statistical analyses were carried out using the STATA statistical software package. RESULTS: The sample consisted of 212 patients (103F; 109M). The age ranged between 3 and 16 years with an average age of 9.03 years; 82.08% (95% CI 76.24-86.99) of the subjects showed an improvement in collaboration compared to pre-lockdown. Logistic analysis reveals a statistically significant increase of the odds of improvement in patients with a lower pre-lockdown collaboration (OR: 6.05, p = 0.001), in children with a parental presence at home (jobless, OR : 30.55, p <0.001; in "smart working", OR: 23.06, p <0.001) when compared to children whose parents work away from home. From a further exploratory analysis, time dedicated to home oral hygiene was increased if associated with an increased presence of the parents at home (p = 0.015). CONCLUSION: Changes in family routines and increased parental presence at home, during the COVID-19 pandemic lockdown, are associated with improved collaboration of children during dental sessions. A statistical association between the increase in time spent on oral hygiene and the increased presence of parents at home was found.

A case of epilepsia partialis continua of abdominal muscles after brain tumor surgery.

Epilepsia partialis continua (EPC) is a rare form of focal motor status epilepticus characterized by continuous muscular twitches or jerks involving a limited part of the body, usually facial region and distal limb. Although the cerebrovascular disease is known to be one of the most common causes of this condition, other reported cases with predominant abdominal involvement have different aetiologies, including, tumors, focal cortical dysplasia, and central nervous system infections. No cases of epilepsia partialis continua of the abdominal wall occurred after brain surgery have been previously reported. We describe the clinical, electrophysiological, and neuroimaging findings in an adult patient presenting with persistent unilateral abdominal myoclonus configuring an EPC as the evolution of a super-refractory hemibody convulsive status epilepticus, occurred after brain tumor surgery.

Insight into epileptic and physiological déjà vu: from a multicentric cohort study.

BACKGROUND AND PURPOSE: The presence of a continuum between physiological déjà vu (DV) and epileptic DV is still not known as well as epidemiological data in the Italian population. The aim was to identify the epidemiological distribution of DV in Italy, and secondly to look for specific features of DV able to discriminate between epileptic and non-epileptic DV. METHODS: In all, 1000 individuals, 543 healthy controls (C) (313 women; age 40 ± 15 years) and 457 patients with epilepsy (E) (260 women; age 39 ± 14 years), were prospectively recruited from 10 outpatient neurological clinics throughout Italy. All populations were screened using the Italian Inventory for Déjà Vu Experiences Assessment (I-IDEA) test and E and pairwise C underwent a comprehensive epilepsy interview. RESULTS: Of E, 69% stated that they experienced 'recognition' and 13.2% reported that this feeling occurred from a few times a month to at least weekly (versus 7.7% of the control group). Furthermore, a greater percentage of E (6.8% vs. 2.2%) reported that from a few times a month to at least weekly they felt that it seemed as though everything around was not real. In E, the feeling of recognition raised fright (22.3% vs. 13.2%) and a sense of oppression (19.4% vs. 9.4%). A fifth of E felt recognition during epileptic seizures. CONCLUSION: Only E regardless of aetiology firmly answered that they had the feeling of recognition during an epileptic seizure; thus question 14 of the I-IDEA test part 2 discriminated E from C. Paranormal activity, remembering dreams and travel frequency were mostly correlated to DV in E suggesting that the visual-memory network might be involved in epileptic DV.

Subacute cerebellar ataxia as presenting symptom of systemic lupus erythematosus.

Neuropsychiatric manifestations are commonly observed in systemic lupus erythematosus (SLE) patients. In particular, neurological involvement is known to be more common in patients with positive anticardiolipin antibodies and lupus anticoagulants. Nevertheless, cerebellar ataxia has rarely been reported, especially as the first clinical manifestation of this systemic autoimmune disorder. Cerebral vascular infarction or ischemia, vasogenic oedema and antibody-mediated cerebral vasculopathy or vasculitic process have been supposed as possible aetiologies of acute cerebellar ataxia related to SLE. We report the clinical and radiological features of a woman who developed a rapidly progressive cerebellar syndrome as first sign of SLE; no other cause explaining her cerebellar ataxia was found. The patient improved after high-dose steroids. The appearance of a cerebellar syndrome with unknown aetiology with associated features of possible systemic autoimmune dysfunction, should be taken into account in clinical practice for appropriate diagnostic workup in order to provide effective therapeutic options.

Psychogenic convergence spasm mimicking ocular myasthenia.

A 14-year-old girl presented with a two-years history of fluctuating convergent strabismus, diplopia, and reading difficulty. She has been previously diagnosed by experienced neurologists as having ocular myasthenia and she had been treated for two years with anticholinesterase inhibitors and immunomodulatory drugs. After a thorough medical interview and neurological examination, a diagnosis of psychogenic convergence spasm was made. The patient was then reassured and the symptoms immediately disappeared. She also had psychotherapy and maintained a condition of sustained freedom from symptoms.

Vagal Nerve Stimulation for Drug-Resistant Epilepsy: Adverse Events and Outcome in a Series of Patients with Long-Term Follow-Up.

BACKGROUND: Vagal nerve stimulation (VNS) is a palliative treatment option for drug-resistant epilepsy. The aim of this study was to describe the clinical and demographic features of selected patients scheduled for VNS and to evaluate the long-term efficacy of VNS in seizure control. MATERIALS AND METHODS: Between 2006 and 2013, 32 consecutive epileptic patients (14 male and 18 female) were enrolled at our Institute for VNS implantation. In all cases resective surgery had previously been excluded by the use of a noninvasive presurgical study protocol. Mean age was 32 years (range 18-50), and mean epilepsy duration 23 years (range 11-39). All subjects were followed-up for at least 2 years (mean 6 years, range 2-9) after VNS implantation. Patients were considered responders when a reduction of seizures of more than 50 % was reported. RESULTS: All patients had complex partial seizures, in 81 % of the patients with secondary generalization and in 56 % with drop attacks. Neurological examination revealed focal deficits in 19 % of the patients. Brain magnetic resonance imaging (MRI) was positive in 47 % of the patients. No surgical complications were observed in this series. Three patients were lost to follow-up. Twelve patients were classified as responders. Among the others, 1 patient experienced side effects (snoring and groaning during sleep) and the device was removed. CONCLUSIONS: Our data confirm that VNS is a safe procedure and a valid palliative treatment option for drug-resistant epileptic patients not suitable for resective surgery.

Clinical dissection of childhood occipital epilepsy of Gastaut and prognostic implication.

BACKGROUND AND PURPOSE: Our aim was to describe the clinical and electrical features and the long-term evolution of childhood occipital epilepsy of Gastaut (COE-G) in a cohort of patients and to compare long-term prognosis between patients with and without other epileptic syndromes. METHODS: This was a retrospective analysis of the long-term outcome of epilepsy in 129 patients with COE-G who were referred to 23 Italian epilepsy centres and one in Austria between 1991 and 2004. Patients were evaluated clinically and with electroencephalograms for 10.1-23.0 years. The following clinical characteristics were evaluated: gender, patient age at seizure onset, history of febrile seizures and migraine, family history of epilepsy, duration and seizure manifestations, circadian distribution and frequency of seizures, history of medications including the number of drugs, therapeutic response and final outcome. RESULTS: Visual hallucinations were the first symptom in 62% and the only manifestation in 38.8% of patients. Patients were subdivided into two groups: group A with isolated COE-G; group B with other epileptic syndromes associated with COE-G. The most significant (P < 0.05) difference concerned antiepileptic therapy: in group A, 45 children responded to monotherapy; in group B only 15 children responded to monotherapy. At the end of follow-up, the percentage of seizure-free patients was significantly higher in group A than in group B. CONCLUSIONS: Childhood occipital epilepsy of Gastaut has an overall favourable prognosis and a good response to antiepileptic therapy with resolution of seizures and of electroencephalogram abnormalities. The association of typical COE-G symptoms with other types of seizure could be related to a poor epilepsy outcome.

Dislocations of the elbow in children: long-term follow-up.

BACKGROUND: Dislocation of the elbow in children is considered to be a benign injury in most cases. The aim of this paper is to evaluate whether this condition has late sequelae in the adult age. The study consisted of a retrospective evaluation of patients under 15 years old at the time of injury. METHODS: 40 patients were selected for the follow-up evaluation. The mean age of the children at the time of injury was 10.9 years old (range 5-14 years). Four patients were lost to follow-up, so they were not considered for final clinical evaluation. For the other 36 patients, the follow-up examination was undertaken after an average of 15 years (range 7-22 years). The average age of the patients at the follow-up was 26 (range 18-34 years). RESULTS: At the end of follow-up period, there were few subjective complications. No redislocations occurred. None of the patients had been influenced by their elbow injury in their choice of occupation. X-rays were available for 27 patients. These were graded using Linscheid and Wheeler criteria and were excellent in 14 patients, good in 10 and fair in 3. CONCLUSIONS: Dislocation of the elbow in children is a benign injury in the majority of cases and has a good prognosis in the adult age too in spite of extensive damage to the periarticular structures. Ectopic ossifications are a common finding, but only large periarticular ectopic ossifications were associated with a decrease in range on motion. Extension loss is the most common sequelae. Level of evidence IV.

Stop-event-related potentials from intracranial electrodes reveal a key role of premotor and motor cortices in stopping ongoing movements.

In humans, the ability to withhold manual motor responses seems to rely on a right-lateralized frontal-basal ganglia-thalamic network, including the pre-supplementary motor area and the inferior frontal gyrus (IFG). These areas should drive subthalamic nuclei to implement movement inhibition via the hyperdirect pathway. The output of this network is expected to influence those cortical areas underlying limb movement preparation and initiation, i.e., premotor (PMA) and primary motor (M1) cortices. Electroencephalographic (EEG) studies have shown an enhancement of the N200/P300 complex in the event-related potentials (ERPs) when a planned reaching movement is successfully stopped after the presentation of an infrequent stop-signal. PMA and M1 have been suggested as possible neural sources of this ERP complex but, due to the limited spatial resolution of scalp EEG, it is not yet clear which cortical areas contribute to its generation. To elucidate the role of motor cortices, we recorded epicortical ERPs from the lateral surface of the fronto-temporal lobes of five pharmacoresistant epileptic patients performing a reaching version of the countermanding task while undergoing presurgical monitoring. We consistently found a stereotyped ERP complex on a single-trial level when a movement was successfully cancelled. These ERPs were selectively expressed in M1, PMA, and Brodmann's area (BA) 9 and their onsets preceded the end of the stop process, suggesting a causal involvement in this executive function. Such ERPs also occurred in unsuccessful-stop (US) trials, that is, when subjects moved despite the occurrence of a stop-signal, mostly when they had long reaction times (RTs). These findings support the hypothesis that motor cortices are the final target of the inhibitory command elaborated by the frontal-basal ganglia-thalamic network.

Surgical treatment of Sprengel's shoulder: experience at the Rizzoli Orthopaedic Institute 1975-2010.

The outcome of 56 children (61 shoulders) treated surgically at the Rizzoli Institute between April 1975 and June 2010 for congenital elevation of the scapula is reported. There were 31 girls and 25 boys with a mean age at surgery of 6.4 years (2 to 15). The deformity involved the right shoulder in 20 cases, the left in 31 and was bilateral in five. The degree of the deformity was graded clinically and radiologically according to the classifications of Cavendish and Rigault, respectively. All patients underwent a modified Green procedure combined, in selected cases, with resection of the superomedial portion of the scapula and excision of any omovertebral connection. After a mean follow-up of 10.9 years (1 to 29.3), there was cosmetic improvement by at least one Cavendish grade in 54 shoulders (88.5%). The mean abduction of the shoulder improved from 92° (50° to 155°) to 112° (90° to 170°) and the mean flexion improved from 121° (80° to 160°) to 155° (120° to 175°). The unsatisfactory cosmetic result in seven shoulders was due to coexistent scoliosis in two cases and insufficient reduction of the scapular elevation in the other five. An incomplete upper brachial plexus palsy occurred post-operatively in three patients but resolved within seven months. We suggest that a modified Green procedure combined with resection of the superomedial portion of the scapula provides good cosmetic and functional results in patients with Sprengel's shoulder.

Tissue plasminogen activator and urokinase plasminogen activator in human epileptogenic pathologies.

A growing body of evidence demonstrates the involvement of plasminogen activators (PAs) in a number of physiologic and pathologic events in the CNS. Induction of both tissue plasminogen activator (tPA) and urokinase plasminogen activator (uPA) has been observed in different experimental models of epilepsy and tPA has been implicated in the mechanisms underlying seizure activity. We investigated the expression and the cellular distribution of tPA and uPA in several epileptogenic pathologies, including hippocampal sclerosis (HS; n=6), and developmental glioneuronal lesions, such as focal cortical dysplasia (FCD, n=6), cortical tubers in patients with the tuberous sclerosis complex (TSC; n=6) and in gangliogliomas (GG; n=6), using immuno-cytochemical, western blot and real-time quantitative PCR analysis. TPA and uPA immunostaining showed increased expression within the epileptogenic lesions compared to control specimens in both glial and neuronal cells (hippocampal neurons in HS and dysplastic neurons in FCD, TSC and GG specimens). Confocal laser scanning microscopy confirmed expression of both proteins in astrocytes and microglia, as well as in microvascular endothelium. Immunoblot demonstrated also up-regulation of the uPA receptor (uPAR; P<0.05). Increased expression of tPA, uPA, uPAR and tissue PA inhibitor type mRNA levels was also detected by PCR analysis in different epileptogenic pathologies (P<0.05). Our data support the role of PA system components in different human focal epileptogenic pathologies, which may critically influence neuronal activity, inflammatory response, as well as contributing to the complex remodeling of the neuronal networks occurring in epileptogenic lesions.

Changes in depression, anxiety, anger, and personality after resective surgery for drug-resistant temporal lobe epilepsy: a 2-year follow-up study.

OBJECTIVE: To further elucidate the psychiatric outcome of surgical treatment for temporal lobe epilepsy (TLE). METHODS: Fifty-two consecutive patients with drug-resistant TLE and IQ > or = 70 completed the Minnesota Multiphasic Personality Inventory, Beck Depression Inventory, Spielberger State-Trait Anxiety Inventory, and Spielberger State-Trait Anger Expression Inventory before epilepsy surgery, after 1 year, and after 2 years. Some patients also completed the 31-item Quality of Life in Epilepsy (N=29) and WHOQOL-100 (N=24) questionnaires. During the follow-up period, patients were maintained on a stable medication regimen. Multivariate repeated measures analysis of variance was used to examine changes in psychiatric variables over time. RESULTS: Seizure outcome was excellent (89% in Engel class I after 2 years). There were only a few significant changes over time in the MMPI profile, suggesting a decrease in interpersonal sensitivity, irritability, and social introversion. Anxiety decreased significantly with a gradual decline, anger dropped significantly after remaining basically flat during the first year, while depression showed a gradual but non-significant decline. Younger age and shorter duration of epilepsy were associated with greater improvement in several anger dimensions. In the patient subgroup with quality of life data available, greater improvement in overall quality of life and key life domains (income, work capacity, personal relationships) was found to be associated with greater decrease in depression, anxiety, and anger. CONCLUSION: The relatively slow decrease of emotional distress over time and its correlation with changes in some key life domains suggest that patients may experience difficulties in switching from a 'sick' role to a 'normal' role, and may easily be disappointed if expectations of positive life changes are not rapidly met. Some counselling sessions early after surgery may be useful to address these issues. The findings also suggest that surgery may yield greater emotional benefits if performed early.
