Wernicke encephalopathy caused by avoidance-restrictive food intake disorder in a child: a case-based review
Background: Wernicke encephalopathy (WE) is an acute and potentially fatal neuropsychiatric disorder resulting from thiamine deficiency: its etiology and clinical presentation can be heterogeneous and arduously recognized, especially in children and adolescents. Case presentation: An 8-year-old girl arrived to the emergency room with ataxic gait, nystagmus, and mental confusion after a 10-day history of repeated severe vomiting; her recent clinical history was characterized by restricted nutrition due to a choking phobia, which caused substantial weight loss. Brain magnetic resonance imaging revealed a bilaterally increased T2 signal in the medial areas of the thalami and cerebral periaqueductal region. Diagnosis of WE based on clinical and neuroradiological findings was established and confirmed after labwork showing low serum thiamine. Following psychiatric evaluation, the patient was also diagnosed with avoidance-restrictive food intake disorder (ARFID), which required starting cognitive behavioral therapy and introducing aripiprazole. The patient displayed improvement of the radiological findings after one month and complete resolution of her neurological symptoms and signs. Conclusions: Eating disorders like ARFID might forerun acute signs of WE; this possibility should be considered even in pediatric patients, especially when atypical neurological pictures or feeding issues come out
Extracranial linear localized scleroderma associated with longstanding epileptic encephalopathy unresponding to methotrexate and prednisone
Prediction of Renal Acid Load in Adult Patients on Parenteral Nutrition
Metabolic acidosis and metabolic bone disease are frequent complications in patients on
parenteral nutrition (PN). A common contributor to these complications could be a daily high renal
acid load. This study aims to find a method for predicting the potential total acid load (PTAL) and
the pH of the compounded parenteral nutrition mixtures. The pH and titratable acidity (TA) of fifty
compounded mixtures were measured. The potential metabolic acid load (PMAL) was calculated
by considering the amount of nutrients that are acid producers and consumers. The PTAL of the
TPN mixtures was calculated by adding TA to PMAL. Multiple linear regression analyses were used
to develop a predictive model for the TA and pH of the compounded mixtures. The predicted TA
and pH values of the analyzed mixtures agreed with those measured (Passing-Bablok analysis).
The PTAL was >50 mmol/day for 82% of the mixtures, >75 mmol/day for 40% of the mixtures, and
>100 mmol/day for 22% of the mixtures. The prediction of the renal acid load in patients on long-term
PN could allow more appropriate acid-base balancing. Moreover, predicting the pH of such mixtures
could be useful to pharmacists to assess the stability and compatibility of the components in the
compounded mixtures
Assessment of bioelectrical phase angle as a predictor of nutritional status in patients with Crohn's disease: A cross sectional study
Subjective palatability and appetite after gluten-free pasta: A pilot study
The interest in gluten-free (GF) diet has greatly increased also in people without celiac disease (CD). This pilot study aimed to investigate the postprandial effect of GF-pasta, made by using the pasta-making process applied to artisan wheat pasta, on palatability, appetite sensation, and glucose metabolism in 8 healthy volunteers. Two iso-caloric lunch-meals consisting of: 1) gluten-free pasta (GFP) and 2) refined wheat pasta (RP) were compared in cross-over design. Both subjective appetite, assessed by visual analogue scale (VAS), and blood sample were taken before meal and at half-hour intervals for 4 hours. Palatability was evaluated immediately after the meal-test by VAS. All participants underwent pre- and postprandial energy expenditure (EE) measured by indirect calorimetry. We found that subjective palatability did not significantly differ between meals. Similarly, repeated measures ANOVA showed that GFP did not affect appetite ratings, postprandial glucose, and insulin responses compared to RP. Then, postprandial EE was affected by time (P=0.006), increasing at 60 min, but not by meals. In conclusion, artisanal GFP was as palatable as RP pasta, without affecting perceived satiety and postprandial glycaemia compared to RP in healthy subjects. Clearly, GFP results are preliminary and need to be investigated in larger studies
Clinical and genetic factors predicting Dravet syndrome in infants with SCN1A mutations
OBJECTIVE: To explore the prognostic value of initial clinical and mutational findings in infants with SCN1A mutations. METHODS: Combining sex, age/fever at first seizure, family history of epilepsy, EEG, and mutation type, we analyzed the accuracy of significant associations in predicting Dravet syndrome vs milder outcomes in 182 mutation carriers ascertained after seizure onset. To assess the diagnostic accuracy of all parameters, we calculated sensitivity, specificity, receiver operating characteristic (ROC) curves, diagnostic odds ratios, and positive and negative predictive values and the accuracy of combined information. We also included in the study demographic and mutational data of the healthy relatives of mutation carrier patients. RESULTS: Ninety-seven individuals (48.5%) had Dravet syndrome, 49 (23.8%) had generalized/genetic epilepsy with febrile seizures plus, 30 (14.8%) had febrile seizures, 6 (3.5%) had focal epilepsy, and 18 (8.9%) were healthy relatives. The association study indicated that age at first seizure and frameshift mutations were associated with Dravet syndrome. The risk of Dravet syndrome was 85% in the 0- to 6-month group, 51% in the 6- to 12-month range, and 0% after the 12th month. ROC analysis identified onset within the sixth month as the diagnostic cutoff for progression to Dravet syndrome (sensitivity = 83.3%, specificity = 76.6%). CONCLUSIONS: In individuals with SCN1A mutations, age at seizure onset appears to predict outcome better than mutation type. Because outcome is not predetermined by genetic factors only, early recognition and treatment that mitigates prolonged/repeated seizures in the first year of life might also limit the progression to epileptic encephalopathy
Fighting autoinflammation in FIRES: The role of interleukins and early immunomodulation
Febrile infection-related epilepsy syndrome (FIRES) is a challenging condition with unfavorable outcome in most cases. Preliminary evidence suggests that some interleukins, in particular IL-1 Receptor Antagonist (IL-1RA), could be elevated due to a functional deficiency of anti-inflammatory pathways. Therefore, treatment strategies acting on innate immunity could represent a targeted treatment. We describe the case of an 11-year-old child with super-refractory status epilepticus (SE), lasting more than two months. After being treated aggressively with antiseizure medications, anesthetics and empiric treatment for autoimmune encephalitis without success, she responded to anakinra and ketogenic diet. Escalation of the therapy was supported by the finding of a very high serum level of IL-1RA. This immunomodulatory approach allowed to discharge the child from intensive care 48 days after the SE onset. After more than one year follow-up the patient has moderate intellectual disability but with good language skills; she is seizure free and without motor deficits. This case suggests that serum IL-1RA serum levels may help to support treatment escalation. Moreover, anakinra and ketogenic diet represent encouraging immunomodulatory strategies which deserve further studies and could potentially have a synergistic effect. Finally, structured neuropsychological testing is an important outcome measure that will help to define the effectiveness of different treatment strategies
Covid-19 infection in children, infants and pregnant subjects: An overview of recent insights and therapies
Background: The SARS-CoV-2 pandemic has involved a severe increase of cases worldwide in a wide range of populations. The aim of the present investigation was to evaluate recent insights about COVID-19 infection in children, infants and pregnant subjects. Methods: a literature overview was performed including clinical trials, in vitro studies, reviews and published guidelines regarding the present paper topic. A descriptive synthesis was performed to evaluate recent insights and the effectiveness of therapies for SARS-CoV-2 infection in children, infants and pregnant subjects. Results: Insufficient data are available regarding the relationship between COVID-19 and the clinical risk of spontaneous abortion and premature foetus death. A decrease in the incidence of COVID-19 could be correlated to a minor expression of ACE2 in childrens’ lungs. At present, a modulation of the dose-effect posology for children and infants is necessary. Conclusions: Pregnant vertical transmission has been hypothesised for SARS-CoV-2 infection. Vaccines are necessary to achieve mass immunity for children and also pregnant subjects
