RESUMEN
Haemolytic Uraemic Syndrome (HUS) is a rare medical condition characterised by microangiopathic haemolytic anaemia, thrombocytopenia, and acute kidney injury. Neurological complications are documented but rarely involve the cerebellum. We present a unique case of a 23-month-old male with HUS triggered by Escherichia coli-O157 (E.coli-O157) infection leading to an isolated cerebellar stroke.The patient initially presented with fever, bloody stools, and seizures. Confirmation of E.coli-O157 infection was obtained, and MRI revealed an isolated cerebellar stroke. Treatment included supportive care, anticoagulation for a right atrial thrombus, with gradual improvement observed.This case highlights the unusual occurrence of isolated cerebellar stroke in HUS patients, emphasising the importance of promptly recognizing manifestations of the central nervous system and the necessity for a multidisciplinary approach. Finally, a comprehensive literature review was conducted to identify cases of HUS patients with cerebellar involvement.
RESUMEN
BACKGROUND: Point-of-care ultrasound (POCUS) is becoming increasingly crucial in the Pediatric Emergency Department for objective patient examination. However, despite its growing interest and wide-ranging applications, POCUS remains relatively unexplored in general pediatric training and education. Many physicians still find it challenging to comprehend and implement. METHODS: A theoretical-practical POCUS course for pediatric residents was conducted at the University of Catania, Italy. The course's effectiveness and practical impact on residents was assessed through a pre-post training survey. The first part of the questionnaire focused on the self-perceived time needed to learn how to recognize the following conditions using POCUS: (i) Pleural effusion (ii) Lung consolidation (iii) Pneumothorax (PNX) (iv) Cardiac contractility (v) Pericardial effusion (vi) Perisplenic effusion (vii) Morison's pouch effusion (viii) Douglas' pouch effusion (ix) Filling and collapsibility of the inferior vena cava. In the second part, we compared the potential role of POCUS in (i) Reducing the use of ionizing radiation in children (ii) Increasing the sense of security in diagnosis and treatment decisions making and (iii) Increasing the residents' confidence level with POCUS after the course on a 1-to-10 rating scale. RESULTS: Seventy-two residents participated in the study. The statistical analysis showed significant pre-post differences in almost all the items considered, except for "cardiac contractility" and "PNX". Furthermore, the perceived potential role of POCUS in reducing ionizing radiation usage and the sense of security in diagnosis and treatment decisions showed statistically significant differences (p < 0.05) before and after the course. Data analysis also revealed a consistently high confidence level with POCUS after the course. CONCLUSIONS: The results highlight the importance of including a POCUS track course in pediatric post-graduate programs due to its simplicity, rapid learning time, and clinical usefulness. Based on these findings, it would be recommended to increase the teaching hours dedicated to the recognition of pneumothorax and cardiology POCUS examination. Emphasizing POCUS training in pediatric education can enhance patient care and diagnostic accuracy while minimizing radiation exposure.

BACKGROUND: Different temporizing neurosurgical procedures are available for the management of posthemorrhagic hydrocephalus in preterm newborns. OBJECTIVE: To evaluate the short efficacy of the external ventricular drains (EVDs) and the ventriculosubgaleal (VSG) shunt. METHODS: This is a Strengthening the Reporting of Observational Studies in Epidemiology-conformed retrospective cohort study. The inclusion criteria were (1) gestational age <37 weeks, (2) birth weight <1500 g, (3) posthemorrhagic hydrocephalus because of intraventricular hemorrhage grade II/III, and (4) EVD or VSG shunt procedure before ventriculoperitoneal (VP)-definite shunt. Twenty-four newborns were collected from 2006 to 2022. The end points considered were infectious events, proteinorrachia, reintervention rate, and time to conversion to definite VP shunt. RESULTS: Overall, 12/24 newborns underwent EVD, and the remnant had a VSG shunt. The results showed a statistically significant difference ( P = .02) concerning cerebrospinal fluid infections between the EVD group (50%) and VSG shunt 1 (8.33%). The reintervention rate of EVD was significantly higher (66.67%) compared with that of the VSG shunt group (8.33%). A statistically significant difference was stated between the 2 groups (t[13] = -8.250; P < .001) (mean difference ± standard error; 10.5 ± 1.273) in the mean number of days elapsed from the achievement of the ideal weight (2000 g) to the definitive VP drainage. CONCLUSION: The increased infectious risk and the higher reintervention rate in EVD were confirmed in this study. In addition, a significant delay in the time to -conversion from EVD to VP shunt was demonstrated. Despite these optimal results, the VSG shunt remains a low practiced intervention, probably because of the limited operator experience.

Background: The COVID-19 pandemic has dramatically affected the global epidemiology of other infectious respiratory diseases, leading to a significant decrease in their incidence. Hence, we aimed to characterize the epidemiology of RSV-bronchiolitis in children. Methods: children aged ≤2 years diagnosed with RSV-mediated bronchiolitis admitted to our Unit from October 2018 to December 2021, were retrospectively enrolled. Results: We included 95 patients (M/F = 46/49; mean age 7.56 ± 6.6 months). Specifically, 17 infants in 2018, 34 in 2019, 0 during 2020 lockdown, 1 during 2020 post-lockdown, and 43 in 2021. Incidence was significantly lower in 2020 compared with 2018, 2019 and 2021 (p < 0.05). No differences were found concerning need for respiratory support. Discussion: Several factors related to SARS-CoV-2 pandemic, especially restrictive measures, may have contributed to a significant reduction in hospitalizations due to RSV. The new outbreak in RSV infection-related hospitalizations reported between October and December 2021 has been suggested it may be due to an increased number of susceptible individuals to RSV infection. Conclusion: The experience of the SARS-CoV-2 outbreak has led to a marked decrease in other viral respiratory infections, such as RSV. This may pave the way for new approaches in preventing respiratory infections, highlighting the role of preventive measures.
RESUMEN
BACKGROUND: Ophthalmoplegic migraine, renamed "Recurrent Painful Ophthalmoplegic Neuropathy" (RPON) in 2013 by the International Headache Society is a rare neurologic disorder characterized by recurrent attacks of ophthalmoplegia associated to ipsilateral headache. The etiology is still unknown. Typical magnetic resonance imaging findings show a focal nerve thickening and contrast enhancement. In the majority of cases, there is a full recovery within days or weeks. There is no evidence supporting a specific treatment. The review defines the characteristics of the recurrent painful ophthalmoplegic neuropathy in patients within 2 years of age underlying the importance of the role of magnetic resonance imaging even in presence of the first attack. Thus, an emblematic case report is presented. CASE PRESENTATION: The authors present a case of third cranial nerve paresis in a 17-month-old male child, presenting a neuroradiological pattern highly suggestive of schwannoma, aneurism or recurrent painful ophthalmoplegic neuropathy. Thus, a review of the literature with the pediatric casuistry of recurrent painful ophthalmoplegic neuropathy occurred within 2 years of age focusing on diagnostic considerations is presented. The authors highlight the importance to consider recurrent painful ophthalmoplegic neuropathy in presence of magnetic resonance imaging findings and clinical symptoms referable to aneurysm or schwannoma. Thus, the review defines the characteristics and the neuroradiological findings at the first RPON attack occurred under 2 years of age. CONCLUSION: Although two attacks are necessary, the review strongly suggests to consider recurrent painful ophthalmoplegic neuropathy even at the first attack, in presence of described characteristics and the aforementioned magnetic resonance imaging findings.

Although rare, ischemic lesions in neonates may occur in Neonatal Intensive Care Units (NICUs) secondary to routine procedures and/or medicaments. We present double-center case series, reporting three preterm neonates with ischemic lesions following cardiac arrest and radial blood sampling. The overall outcome after treatment with 2% nitroglycerine (NTG) ointment showed optimal results with no adverse events. The most frequent causes responsible for the onset of such lesions are peripheral arterial catheterization procedures and dopamine extravasation. Our series describe the cardiac arrest as an underestimated cause of onset. Despite the optimal results emerging from the treatment of such lesions with NTG ointment, both in our experience and in the scientific literature, a defined protocol for its use in NICUs is not currently available, hence the need for further studies.

The prevalence of idiopathic oligozoospermia has been esteemed as high as 75%. An Italian survey has reported bilateral testicular hypotrophy in 14% of final-year high school students. The search for determinants of testicular growth in childhood is important for the primary prevention of spermatogenic failure. Therefore, this retrospective study aimed to evaluate the testicular growth and pubertal onset in deficient children treated recombinant human growth hormone (rhGH). To accomplish this, the clinical charts of 93 patients with GH deficiency (GHD) were carefully reviewed. Their mean age at the time of diagnosis was 11.2 ± 2.4 years. rhGH was administered for 44.0 ± 22.4 months, and the onset of puberty was recorded after a mean of 25.8 ± 22.4 months from the first rhGH administration. As expected, serum insulin-like growth factor 1 (IGF1) levels increased significantly after treatment. Before rhGH therapy, the Tanner stage was I in 59 out of 70 boys (84.3%), II in 8/70 (11.4%), III in 3/70 (4.3%). No one was on stage IV or V. The mean Tanner stage was 1.19 ± 0.51. At the last visit, the Tanner stage was I in 8/72 boys (11.1%), II in 6/72 (8.3%), III in 6/72 (8.3%), IV in 16/72 (22.2%), and V in 36/72 (50.0%). After a mean of 44.0 ± 22.4 months of rhGH treatment, the mean Tanner stage was 4.05 ± 1.30. Patients treated with rhGH showed a significant testicular volume (TV) growth over time, whereas no growth was observed in age-matched but not yet treated patients, even when the age was compatible with a spontaneous start of puberty. The multivariate regression analysis showed that the duration of treatment and the mean rhGH dose significantly predicted the percentage of TV increase. In contrast, age, serum FSH, and IGF1 levels, and final rhGH dose did not impact TV growth over time. In conclusion, these findings suggest that GH may play a role in testicular growth and pubertal onset, despite the descriptive nature of this study. Further properly designed studies are needed to confirm these findings. This knowledge may be useful to implement the diagnostic-therapeutic algorithm in case of a lack of testicular growth in childhood.

The 8p inverted duplication/deletion is a rare chromosomal rearrangement clinically featuring neurodevelopmental delay, mild to severe cognitive impairment, heart congenital defects and brain abnormalities. Patients affected also present typical facial dysmorphisms and skeletal malformations, and it is thought that the composite clinical picture may fall into the chromosomal rearrangement architecture. With the major aim of better framing its related clinical and diagnostic paths, we describe a patient carrying a de novo invdupde[8p] whose clinical features have not been described so far. Hence, through an extensive genotype-phenotype correlation analysis and by reviewing the dedicated scientific literature, we compared our patient's features with those reported in other patients, which allows us to place our proband's expressiveness in an intermediate area, widening the scope of the already known invdupde[8p] genotype-phenotype relationship.
