Refeeding syndrome and psychopharmacological interventions in children and adolescents with Anorexia Nervosa: a focus on olanzapine-related modifications of electrolyte balance.

This study aims to investigate the potential correlation between the use of olanzapine, a psychopharmacological intervention commonly prescribed in Anorexia Nervosa treatment, and the occurrence of Refeeding Syndrome. Despite the acknowledged nutritional and biochemical impacts of olanzapine, the literature lacks information regarding its specific association with Refeeding Syndrome onset in individuals with Anorexia Nervosa. This is a naturalistic, retrospective, observational study, reporting the occurrence of Refeeding Syndrome in children and adolescents with Anorexia Nervosa, treated or untreated with olanzapine. Dosages and serum levels of olanzapine were assessed for potential associations with the occurrence of Refeeding Syndrome and specific variations in Refeeding Syndrome-related electrolytes. Overall, 113 patients were enrolled, including 46 (41%) who developed a Refeeding Syndrome. Mild (87%), moderate (6.5%), and severe (6.5%) Refeeding Syndrome was described, at a current average intake of 1378 ± 289 kcal/day (39 ± 7.7 kcal/kg/die), frequently associated with nasogastric tube (39%) or parenteral (2.2%) nutrition. Individuals receiving olanzapine experienced a more positive phosphorus balance than those who did not (F(1,110) = 4.835, p = 0.030), but no difference in the occurrence of Refeeding Syndrome was documented. The mean prescribed doses and serum concentrations of olanzapine were comparable between Refeeding Syndrome and no-Refeeding Syndrome patients.    Conclusion: The present paper describes the occurrence of Refeeding Syndrome and its association with olanzapine prescriptions in children and adolescents with Anorexia Nervosa. Olanzapine was associated with a more positive phosphorus balance, but not with a different occurrence of Refeeding Syndrome. Further, longitudinal studies are required. What is Known: • Refeeding Syndrome (RS) is a critical complication during refeeding in malnourished patients, marked by electrolyte (phosphorus, magnesium, potassium) imbalances. • Olanzapine, an atypical antipsychotic with nutritional and biochemical impacts, is used in Anorexia Nervosa (AN) treatment, however data concerning its association with RS are lacking. What is New: • The study observed RS in 46/113 (41%) young patients with AN. • Olanzapine-treated individuals showed a higher improvement in serum phosphate levels than untreated ones, although no impact on the occurrence of Refeeding Syndrome was observed.

Post-Traumatic Headache in Children after Minor Head Trauma: Incidence, Phenotypes, and Risk Factors.

Minor head trauma (MHT) is very frequent in children and post-traumatic headache (PTH) is one of its most common complications; however, its management is still a challenge. We aimed to assess the incidence and clinical characteristics of, and risk factors for, PTH among children referred to our pediatric emergency department (PED) for MHT. A total of 193 patients aged 3-14 years evaluated for MTH were enrolled and followed up for 6 months through phone calls and/or visits. PTH occurred in 25/193 patients (13%). PTH prevalence was significantly higher in school-aged (≥6 years) than in pre-school-aged children (21.6% vs. 4.9%, respectively, p < 0.009). Females were found to be more affected. The median time of onset was 4.6 days after MHT; resolution occurred in a median of 7 weeks. In 83.3% of patients, PTH subsided in <3 months, while in 16.7% it persisted longer. A total of 25% of children exhibited the migraine and 75% the tension-type variant. Our analysis indicates the presence of headache upon arrival in PED, isolated or associated with nausea and dizziness, as a factor predisposing the patient to the development of PTH. Our findings could be useful to identify children at risk for PTH for specific follow-up, family counseling, and treatment.

Anorexia nervosa among first- and second-generation immigrant children and adolescents in Italy: treatment and clinical outcomes.

PURPOSE: Cultural and environmental factors have frequently been implicated in the pathogenesis of Eating Disorders (ED). Although ED have been considered as "Western culture-bound syndromes", increasing rates of ED among non-Western groups are being documented. The present study aims to investigate treatment and clinical outcomes among first-generation immigrant children and adolescents (FGI) (patients born abroad) and second-generation immigrant youth (SGI, patients born in Italy) with Anorexia Nervosa (AN). METHODS: The study retrospectively compares treatment, hospitalizations, traumatic past events, clinical features, and treatment outcome (improvement in percentual body-mass index - %BMI) between FGI and SGI young patients with AN (10-18 years). Correlations were adjusted for age and severity (%BMI) at presentation. Treatments and outcomes were investigated at the baseline (T0), 2 weeks (T1), one month (T2), 3 months (T3), 6 months (T4), and 12 months (T5). RESULTS: Thirty-six patients (50% FGI) were enrolled. At T1 (F(1.26)=6.335, p=0.018), and at T2 (F(1.30)=18.752, p<0.001) FGI presented a significantly higher %BMI improvement than SGI. FGI required significantly less (OR=0.379, p=0.017), and shorter (F(1.32)=5.827, p=0.022) hospitalizations, when compared with SGI. CONCLUSIONS: When compared to SGI, FGI with AN required fewer and shorter hospitalizations and had a better early-treatment weight outcome. Larger nationwide studies should investigate the need for and access to treatment of immigrant populations with AN.

Timing of Psychopharmacological and Nutritional Interventions in the Inpatient Treatment of Anorexia Nervosa: An Observational Study.

This study aims to investigate possible different outcomes in the inpatient treatment of anorexia nervosa (AN) related to different timings of psychopharmacological and nutritional interventions. A retrospective observational study was conducted, involving young patients hospitalized for AN, treated with naso-gastric tube feeding (NGT). Participants were divided into five groups according to early (0-7 days) or late (8+ days) introduction of atypical antipsychotics (AAP) and NGT: early AAP-early NGT (EE), early AAP-late NGT (EL), late AAP-early NGT (LE), late AAP-late NGT (LL) and a control group treated with NGT only (NGT). Concurrent clinical and treatment variables were analyzed. AN psychopathology was measured with the Eating Disorder Inventory-3 (EDI-3) EDRC score. Outcomes were assessed as admission-discharge body-mass index (BMI) improvement and length of hospital stay (LOS). Contributions of variables related to outcomes were assessed with multifactorial-analyses of variance (MANOVA). Seventy-nine patients were enrolled in the study. LOS was different among treatment groups (F (4, 75) = 5.993, p < 0.001), and EE patients showed lower LOS than LE (p < 0.001) and LL (p = 0.025) patients. BMI improvement was not significantly different among treatment groups but correlated negatively with age (F (1, 72) = 10.130, p = 0.002), and admission BMI (F (1, 72) = 14.681, p < 0.001). In conclusion, patients treated with early AAP and early NGT showed lower LOS than those treated with late AAP. Prognostic treatment variables should be investigated in wider samples.

First Attack and Clinical Presentation of Hemiplegic Migraine in Pediatric Age: A Multicenter Retrospective Study and Literature Review.

Background: Data on clinical presentation of Hemiplegic Migraine (HM) are quite limited in the literature, particularly in the pediatric age. The aim of the present study is to describe in detail the phenotypic features at onset and during the first years of disease of sporadic (SHM) and familial (FHM) pediatric hemiplegic migraine and to review the pertinent literature. Results: Retrospective study of a cohort of children and adolescents diagnosed with hemiplegic migraine, recruited from 11 Italian specialized Juvenile Headache Centers. Forty-six cases (24 females) were collected and divided in two subgroups: 32 SHM (16 females), 14 FHM (8 females). Mean age at onset was 10.5 ± 3.8 y (range: 2-16 y). Mean duration of motor aura was 3.5 h (range: 5 min-48 h). SHM cases experienced more prolonged attacks than FHM cases, with significantly longer duration of both motor aura and of total HM attack. Sensory (65%) and basilar-type auras (63%) were frequently associated to the motor aura, without significant differences between SHM and FHM. At follow-up (mean duration 4.4 years) the mean frequency of attacks was 2.2 per year in the first year after disease onset, higher in FHM than in SHM cases (3.9 vs. 1.5 per year, respectively). A literature review retrieved seven studies, all but one were based on mixed adults and children cohorts. Conclusions: This study represents the first Italian pediatric series of HM ever reported, including both FHM and SHM patients. Our cohort highlights that in the pediatric HM has an heterogeneous clinical onset. Children present fewer non-motor auras as compared to adults and in some cases the first attack is preceded by transient neurological signs and symptoms in early childhood. In SHM cases, attacks were less frequent but more severe and prolonged, while FHM patients had less intense but more frequent attacks and a longer phase of active disease. Differently from previous studies, the majority of our cases, even with early onset and severe attacks, had a favorable clinical evolution.

An observational study of fixed-dose Tanacetum parthenium nutraceutical preparation for prophylaxis of pediatric headache.

BACKGROUND: Migraine is one of the most prevalent chronic pain manifestations of childhood. Despite the multitude of available treatments, parents are often concerned about chronic therapies and pediatricians have insufficient confidence in prescribing prophylactic drugs. Therefore, there is now growing interest for natural supplements used to control recurrent migraine headaches. Such approach may increase acceptance and adherence to long-term prophylaxis therapy in children. METHODS: This is an observational multicenter study performed in children (n = 91) with migraine, with (MO) or without aura (MA), or tension-type headache (TTH). A fixed-dose Andrographis paniculata, CoQ10, riboflavin, and magnesium, was administered for 16 weeks. Patients were evaluated at baseline (T0), at week 8 (T1) and at the end of treatment at week 16 (T2). A follow-up period occurred at week 20 (T3) and week 32 (T4). RESULTS: The herbal supplement significantly reduced the frequency of headaches in TTH patients during treatment period (T0: 11.97 + 1.92 vs T2: 5.13 + 1.93; p < 0.001) and the efficacy was maintained after 16 weeks of treatment withdrawal (T4: 4.46 + 1.75; p < 0.001 vs T0). The frequency of migraine attacks was also reduced in the MO group during treatment (T0: 9.70 + 0.96 vs T2: 4.03 + 0.75; p < 0.01) and after withdrawal (T4: 2.96 + 0.65; p < 0.01 vs T0). Conversely, MA patients showed reduction in migraine's frequency during treatment (T0: 8.74 + 1.91 vs T2: 3.78 + 2.02; p < 0.01) but not at the end of the study (T4: 5.57 + 3.31; p > 0.05 vs T0). TTH patients did not report significant improvement of pain intensity. A significant effect was observed in the MO group during treatment (T0: 3.06 + 0.11 vs T2: 2.14 + 0.19; p < 0.001) and after treatment withdrawal (T4: 2.20 + 0.21; p < 0.001 vs T0). Likewise, MA group showed a significant treatment effect (T0: 2.57 + 0.20 vs T2: 0.86 + 0.45; p < 0.001) and the efficacy persisted at the end of the study (T4: 1.00 + 0.58; p < 0.001 vs T0). CONCLUSION: This fixed-dose Tanacetum parthenium preparation improved headache frequency and pain intensity in children affected by TTH. Despite the main limits, this study supports the use of nutraceutical in pediatric headache/migraine.

Audit of digestive complaints and psychopathological traits in patients with eating disorders: a prospective study.

BACKGROUND: Esophago-gastrointestinal symptoms are frequently reported by patients with eating disorders. Scanty data exist on the relationship between psychopathological traits and digestive complaints. AIMS: To prospectively analyze (i) prevalence of digestive symptoms; (ii) psychopathological traits; (iii) relationship between symptom scores and psychopathological profiles. METHODS: Psychopathological and digestive symptom questionnaires were completed at baseline, at discharge, at 1 and 6 months' follow-up in 48 consecutive patients (85.4% female, median age, 15 years) hospitalized for eating disorders. RESULTS: The most frequently reported symptoms were postprandial fullness (96%) and abdominal distention (90%). Pooled esophageal (4; IQR 0-14) and gastrointestinal (34; IQR 19-53) symptoms significantly decreased at 6 months' follow-up (1; IQR 0-3 and 10; IQR 4-34; p<0.0001 and p<0.005, respectively). Pooled gastrointestinal symptoms significantly correlated with hypochondriasis (r=0.42, p<0.01). Both esophageal and gastrointestinal symptoms improved in patients with normal values of hypochondriasis and hysteria scales (p<0.05 and p<0.005, respectively) compared to those with pathological traits. CONCLUSIONS: Digestive symptoms are frequently reported by patients with eating disorders with their expression and outcome being influenced by psychopathological profiles. Hypochondriasis and hysteria traits are predictive factors for symptomatic improvement.

VNS in drug resistant epilepsy: preliminary report on a small group of patients.

BACKGROUND: In 1997 Vagus Nerve Stimulation (VNS) received approval from the US Food and Drug Administration (FDA) as an adjunctive therapy in the treatment of medically intractable partial epilepsy in people aged 12 years and older who are ineligible for resective epilepsy surgery. Although the exact mechanisms of action are unknown, the use of VNS with children has increased, including those younger than 12 years of age, or those with generalized epilepsy. METHODS: We describe the outcome for the first group of nine patients, aged 8-28 years, who had pharmaco-resistant epilepsy and were treated with VNS. During the follow up, we gradually and slowly increased the parameters of the stimulation in order to assess the efficacy of VNS even at parameters which would usually be considered "non-therapeutic", along with possible side effects and changes in quality of life. RESULTS: At the last follow, up 1 patient was "seizures free", 3 were "very good responders", 3 were "good responders" and 2 were "non responders". We obtained an initial seizure reduction with low stimulation parameters, the highest current reached being 2.00 mA. This observation supports the possibility that, for younger patients, lower stimulation intensities than those commonly used in clinical practice for adults can be therapeutic. We also wanted to underline the reduction in seizure frequency (approximately 91.7%) and the reduction in seizure duration (> 50%) in the patients affected by drug-resistant absence epilepsy. Adverse effects were mild, tolerable and, in most of cases, easily resolved by adjusting the stimulation parameters. Hoarseness of voice was the most frequent side effect. The improvements in the quality of life are relevant and seem to be independent of the VNS effect in controlling seizures. CONCLUSIONS: Our small experience seems to confirm the efficacy and safety of VNS in drug resistant partial and generalized epilepsy in developing age groups.

Prospective study on long-term treatment with oxcarbazepine in pediatric epilepsy.

Following a previous preliminary report on a group of children suffering from partial epilepsies, we present the final considerations on the same group in order to evaluate the long-term efficacy, tolerability and safety of oxcarbazepine (OXC). We enrolled 36 patients (mean age 8.5), between January 2003 and December 2004, with new diagnosis of partial epilepsy: 25 patients were affected by idiopathic partial epilepsy, eight by symptomatic epilepsy and three by cryptogenic epilepsy. Each patient was scheduled to attend the center four times after the initial examination: 3 months (T1), 12 months (T2), 24 (T3) months and 36 (T4) months after the beginning of OXC-monotherapy (T0). At the end of our study, 20 patients were seizure free (SF): nine stopped OXC because of SF for at least 2 years, 11 were still on therapy. One patient showed a reduction of seizure frequency >or=50%, three were non responders (but still on therapy), nine stopped OXC due to a non-responder condition during follow-up before T4 and one because of adverse effects. At the end of the study no EEG focal abnormalities became generalized because of treatment. Normalization of EEG was observed in ten patients. Our preliminary findings have been confirmed. OXC can be considered an effective and well tolerated first line drug for long-term monotherapy in children with epilepsy, both for idiopathic and symptomatic/cryptogenic forms.

Unusual diagnosis in a child suffering from juvenile Alexander disease: clinical and imaging report.

Alexander disease is a rare, sporadic leukoencephalopathy characterized by white-matter abnormalities with frontal predominance and, as a rule, clinically associated with megalencephaly, seizures, spasticity, and psychomotor deterioration. We describe a boy who was diagnosed as affected by anorexia nervosa because of his refusal to eat, progressive weight loss, and psychologic disturbances. The observation of a hyperintense lesion on T(2)-weighed magnetic resonance images (MRIs) was initially explained as a pontine and extrapontine myelinolysis related to malnutrition. Following MRI and DNA analysis, we diagnosed a juvenile type of Alexander disease. Therefore, we can affirm the importance of the history and clinical examination to look for brainstem dysfunction in patients presenting with atypical anorexia nervosa.

Efficacy and safety of topiramate in refractory epilepsy of childhood: long-term follow-up study.

This study aimed to evaluate the long-term efficacy and safety of topiramate in treating children with drug-resistant epilepsy. A multicentric, retrospective, open-label, add-on study was undertaken of 277 children (mean age 8.4 years; range 12 months to 16 years) affected by drug-resistant epilepsy. The efficacy was rated according to the seizure types and epilepsy syndrome. After a mean period of 27.5 months of treatment (range 24-61 months), 11 patients (4%) were seizure free and 56 (20%) had more than 50% reduction in seizure frequency. The efficacy of topiramate treatment was noted in localization-related epilepsy and in generalized epilepsy. In addition, in a group of 114 patients, we compared the initial efficacy (evaluated after a mean of 9 months of follow-up) and the retention at a mean of 30 months of topiramate with regard to loss of efficacy (defined as the return to the baseline seizure frequency). Fifty-five (48%) of 114 patients were initial responders. The retention at a mean of 30 months was 23 of 114 patients (20%), 4 of whom (3.5%) were still seizure free. A loss of efficacy occurred in 32 of the 55 initial responders (58%). It was prominent in patients with generalized epilepsy, such as symptomatic infantile spasms and Lennox-Gastaut syndrome, as well as in those with Dravet syndrome. By contrast, a well-sustained topiramate efficacy was noted among patients with localization-related epilepsy. Globally, adverse events were observed in 161 patients (58%) and were mainly represented by weight loss, hyperthermia, sedation, and nervousness, which, in most cases, disappeared after slowing titration or reducing the dosage of the drug. In conclusion, the present long-term study confirms that topiramate represents a useful drug effective in a wide range of seizures and epilepsy syndromes. Moreover, preliminary data seem to suggest that the efficacy of topiramate, when evaluated in the long-term perspective, is more sustained in localization-related epilepsy than in generalized epilepsy.

Short-term nonhormonal and nonsteroid treatment in West syndrome.

PURPOSE: West syndrome (WS) is considered an age-dependent epileptic encephalopathy and also a particular type of electrical epileptic status. Short-term hormonal or steroid treatment of WS with good efficacy is reported in the literature. The aim of this retrospective multiinstitutional study was to evaluate the early discontinuation of nonhormonal and nonsteroid treatment for WS. METHODS: Twenty-two WS cases in which treatment was discontinued after a maximum of 6 months, were collected. Inclusion criteria were the presence of typical EEG hypsarrhythmia (HY) and video-EEG recorded epileptic spasms. Exclusion criteria were the presence of partial seizures or other seizure types before spasm onset. The patients were treated with vigabatrin (VGB) in 19 cases and nitrazepam (NTZ) in three. The dose range was 70-130 mg/kg/day for VGB and 0.7-1.5 mg/kg/day for NTZ. The drug was discontinued if spasms stopped and HY disappeared after a mean treatment period of 5.1 months (range, 3-6 months). All patients underwent repeated and prolonged awake and sleep video-EEG, both before and after drug discontinuation. RESULTS: Cryptogenic (15) and symptomatic (seven) WS patients were included. All the symptomatic cases had neonatal hypoxic-ischemic encephalopathy. The mean age at spasm onset was 5.5 months (range, 3-7 months; median, 6). The interval between spasm onset and drug administration ranged from 7 to 90 days (mean, 23 days; median, 20). The interval between drug administration and spasm disappearance ranged from 2 to 11 days (mean, 6 days; median, 6 days). The interval between drug administration and HY disappearance ranged from 3 to 30 days (mean, 9 days; median, 10 days). Drugs were stopped progressively over a 30- to 60-day period. Follow-up ranged from 13 to 50 months (mean, 26 months; median, 22 months). None of our cases showed spasm recurrence. CONCLUSIONS: Our data show that successful nonhormonal and nonsteroid treatment can be shortened to a few months without spasm recurrence in patients with cryptogenic or postanoxic WS.
