ABSTRACT

Differentiating between primary and secondary headaches can be challenging, especially in the emergency department (ED). Since symptoms alone are inadequate criteria for distinguishing between primary and secondary headaches, many children with headaches undergo neuroimaging investigations, such as brain CT and MRI. In various studies, the frequency of neuroimaging utilization is influenced by several factors, including teaching status, ownership, metropolitan area, insurance status, and ethnicity of patients. However, only a few studies have considered the role of specialist consultations in ordering neuroimaging studies on childhood headaches. We report the contributions of different specialists to the evaluation of children with headaches admitted to the ED and their influence on neuroimaging decisions. We retrospectively reviewed the medical reports of paediatric patients who presented with headaches to the paediatric ED of the Ospedale Maggiore Policlinico of Milano between January 2017 and January 2022. Overall, 890 children with headaches were evaluated (mean age: 10.0 years; range: 1 to 17 years). All patients were examined by the ED paediatricians, while specialist consultations were required for 261 patients, including 240 neurological (92.0%), 46 ophthalmological (17.6%), and 20 otorhinolaryngological (7.7%) consultations. Overall, 173 neuroimaging examinations were required, of which 51.4 and 48.6% were ordered by paediatricians and neurologists, respectively. In particular, paediatricians required 61.4% of brain CT scans, and neurologists required 92.0% of brain MRI scans. In conclusion, paediatricians were responsible for the management of most children with headaches admitted to the ED, while specialist consultations were required only in about a third of the cases. Although there was no significant difference in the number of neuroimaging studies ordered by specialists, brain CT scans were most often used by paediatricians, and MRI scans by neurologists.

ABSTRACT

Vernal keratoconjunctivitis (VKC) is a chronic, bilateral corneal and conjunctival problem which typically presents in young individuals. VKC is characterized by itching, photophobia, white mucous discharge, lacrimation, foreign body sensation, and pain due to corneal involvement of shield ulcers. Vernal keratoconjunctivitis is categorized within ocular diseases. The diagnosis is clinical, as no sure biomarkers pathognomonic of the disease have yet been identified. The VKC therapy relies on different types of drugs, from antihistamines and topical steroids to cyclosporine or tacrolimus eye drops. In extremely rare cases, there is also the need for surgical treatment for the debridement of ulcers, as well as for advanced glaucoma and cataracts, caused by excessive prolonged use of steroid eye drops. We performed a systematic review of the literature, according to PRISMA guideline recommendations. We searched the PubMed database from January 2016 to June 2023. Search terms were Vernal, Vernal keratoconjunctivitis, and VKC. We initially identified 211 articles. After the screening process, 168 studies were eligible according to our criteria and were included in the review. In this study, we performed a systematic literature review to provide a comprehensive overview of currently available diagnostic methods, management of VKC, and its treatments.

ABSTRACT

Background: Febrile seizures (FS) and benign convulsions in children with mild gastroenteritis (CwG) are acute symptomatic seizures, transiently occurring in infants and young children, probably related to the immaturity of the brain. Our paper aims to review the literature data on patients with FS and CwG. Methods: A review of series of patients with FS and CwG was performed by literature search on PubMed January 1960 to October 2022. Several parameters were considered, including epidemiology, pathophysiology, clinical features, electroencephalographic findings and other diagnostic studies, and treatment. Results: FS and CwG share an age-dependent course, but they show significant differences in the pathophysiology, clinical features, diagnostic studies, and treatment. Conclusion: Acute symptomatic seizures include seizures that are caused by acute structural brain pathologies, such as stroke, as well as seizures that are provoked by a reversible factor, such as hyponatraemia, although the two groups should be not equated. Furthermore, FS and CwG should be set apart as "age-dependent acute symptomatic seizures", reinforcing the concept of their self-limited course over a certain period.

ABSTRACT

Omalizumab, which downregulates the immunoglobulin E (IgE) receptor site on plasmacytoid dendritic cells and thereby increases interferon-α (INF-α) production, may shorten the duration of viral infections by enhancing the antiviral immunity. A systematic review was conducted to investigate whether previous anti-IgE treatment with omalizumab could protect against SARS-CoV-2 disease ("COVID-19") (infection, disease duration, and severity), and whether IFN-α upregulation could be involved. The research included articles published from March 2020 to January 2022. An accurate search was performed on bibliographic biomedical database (MEDLINE - Pubmed, SCOPUS, EMBASE, BIOMED CENTRAL, Google scholar, COCHRANE LIBRARY, ClinicalTrial.gov) including cohorts, case reports and reviews. Different methods were used, based on the study design, to assess the quality of eligible studies. Several authors link omalizumab to a possible protection against viruses, but they often refer to studies carried out before the pandemic and with viruses other than SARS-CoV-2 (severe acute respiratory syndrome coronavirus 2) (eg, rhinoviruses -RV). Few cases of COVID-19 patients treated with omalizumab have been recorded, and, in most of them, no increased susceptibility to severe disease was observed. According to these data, the current indication is to continue omalizumab therapy during the pandemic. Moreover, although omalizumab may enhance the antiviral immune response even for SARS-CoV-2, further studies are needed to confirm this hypothesis. It would be helpful to establish a registry of omalizumab-treated (or in treatment) patients who have developed COVID-19. Finally, randomized controlled trials could be able to demonstrate the effect of omalizumab in protecting against severe SARS-CoV-2, through IFN-α upregulation or other immunological pathways.

ABSTRACT

BACKGROUND: To evaluate the impact of COVID-19 on evaluations in the pediatric emergency department (ED) because of headache as main symptom. METHODS: Number and clinical features of patients evaluated in the pediatric ED of a single site in Milan, Italy, were collected between January 2017 and January 2022. The impact of COVID-19 on evaluation rates was quantified by using the incidence rate ratio (IRR) and 95% confidence intervals (CI) between the pandemic (March 2020 to January 2022) and the prepandemic period (January 2017 to February 2020). RESULTS: During the study period, 890 evaluations were registered: 689 over the prepandemic period and 201 over the pandemic period. Mean age at evaluation was 10 years (range: 1 to 17 years). Evaluation rates per month were 18.1 during the prepandemic period and 8.7 during COVID-19 pandemic, with peaks in autumn and winter months and considerable drops in the summer. The IRR was 0.49 (95% CI, 0.40-0.61). The reduction in evaluation rate was higher for secondary headache (IRR, 0.31; 95% CI, 0.23-0.42) when compared with primary headache (IRR, 0.56; 95% CI, 0.40-0.78). CONCLUSIONS: We found a remarkable reduction in the number of evaluations in the pediatric ED for headache during the pandemic period.

ABSTRACT

Bathing epilepsy is a rare form of reflex epilepsy triggered by bathing in room temperature water. It predominates in boys with a mean age of 15 months and its evolution is benign. Diagnosis of bathing epilepsy requires the exclusion of other paroxysmal disorders triggered by water contact. Video-EEG confirmation of the seizures is necessary to reach a diagnosis of certainty and to allow adequate management. We present the case of a one-year-old boy who experienced recurrent episodes of unresponsiveness and cyanosis while bathing in lukewarm water. The diagnosis of bathing epilepsy was confirmed by the video-EEG recording of a seizure, showing left-sided frontotemporal delta activity with rapid contralateral spread. Therapy with levetiracetam was effective, subsequently allowing bathing without further seizures.

ABSTRACT

In this study, a sensitive quantitative method based on high performance liquid chromatography combined with high-resolution mass spectrometry, Q ExactiveTM-Orbitrap® was set up and applied for the determination of the immunosuppressor agents cyclosporine A and tacrolimus in novel ethanol-free ophthalmic formulations for the treatment of Vernal keratoconjunctivitis. Different storage parameters in terms of storage temperatures and practical usage conditions were investigated to assess the stability of all formulations during shelf life simulating the real conditions as well to confirm the feasibility of use of ethanol-free products. The methodology was linear (r2 = 0.995) over the concentration range 0-200 ng/mL, and its selectivity, precision, accuracy and recovery were all within the required limits. Under different conditions (storage period 0-90 days, 5-25 °C, unopened/usage simulated conditions), our results revealed that both active pharmaceutical ingredients (API) show satisfactory stability up to 30 days of storage/usage, with a significant and consistent concentration decline of cyclosporine A after this time point when its hydroalcoholic formulation was kept at 25 °C.

ABSTRACT

BACKGROUND: Children with vernal keratoconjunctivitis (VKC) present symptoms that are similar to other ocular allergies, but more pronounced, and are controlled using topical steroids. To avoid excessive and prolonged use of topical steroid eye drops, over the past 20 years galenic eye drops of cyclosporine with a concentration of 1% to 2% and tacrolimus with a concentration of 0.1% have been introduced as a treatment for the severe and unresponsive forms. The main symptoms of VKC occur most frequently during the spring and tend to get worse during the summer, meaning that affected children tend to avoid exposure to sunlight. The aim of this study was to assess the most common cell types present in the conjunctiva of children with VKC, how ocular treatment can influence them, and whether affected children express a typical conjunctival pattern, which could be useful as a pathognomonic pattern of VKC, allowing us to study this rare eye disease. METHOD: This was a cohort study of 56 children, of whom 17 were not receiving any treatment at the time of testing, 14 were using steroid eye drops or had taken them in the previous 10 days, and 25 were treated with cyclosporine eye drops or tacrolimus eye drops 0.1%. RESULT: Children in group 1 (no topical therapy) express more epithelial cells, neutrophils, mast cells, eosinophils, and lymphocytes than the other two groups. CONCLUSION: Given the ease of performance, when conducting further longitudinal studies, the conjunctival cytology examination could be used, on the one hand, to diagnose VKC, especially when the clinical diagnosis is uncertain, and, on the other, to follow disease evolution and monitor the response to topical treatment.

ABSTRACT

The aim of this study was to evaluate whether the control of ocular symptoms with cyclosporine or with tacrolimus in eye drops allows to improve sun exposure and therefore serum level of vitamin D (VD; 25OHD), in the more severe forms of vernal keratoconjunctivitis (VKC). Out of 242 children followed for active VKC, 94 were treated with 1% cyclosporine or 0.1% tacrolimus eye drops, while the other 148 with mild VKC did not need to be treated with immunomodulators. VD serum levels were measured in spring and autumn in 71 children. In total, 60 of them were treated with cyclosporine eye drops (first group) and 11 (not responding to cyclosporine therapy previously) with 0.1% tacrolimus eye drops (second group) between March and November 2016. Pre-treatment median values of VD were 23.7 ng/mL in the first group and 23.8 in the second group, and post-treatment values increased up to 32.8 and 32.9 ng/mL, respectively. Before treatment, 33% presented a deficiency (25OHD < 20 ng/mL), and at the end of summer, only 4% were deficient. The overweight children had lower improvement in VD serum levels than children with a body mass index (BMI) lower than 85th percentile. Children in therapy with cyclosporine, but requiring the administration of local steroid therapy during the summer for control of the symptoms, showed a greater improvement in 25OHD serum levels in ng/mL (23-37 ng/mL) than children who did not require steroid therapy (24-35 ng/mL). Furthermore, there was a significant difference in change of 25OHD in children presenting limbal VKC (21-41 ng/mL) versus tarsal VKC (24-35 ng/mL) ( P = 0.04). Our study suggests that ocular treatment carried out with immunomodulator eye drops could allow for an improvement in 25OHD serum levels. In children with active VKC and at risk of 25OHD deficiency, likely due to avoidance of sun exposure, the role of other risk factors (BMI, phototype and treatment) on 25OHD serum levels should be considered.
