ABSTRACT
OBJECTIVES: We summarized the clinical and radiological characteristics of meningitis-retention syndrome (MRS), its therapeutic options, and urological outcome, to better understand the pathogenesis of this syndrome and to evaluate the effectiveness of corticosteroids in reducing the period of urinary retention. METHODS: We reported a new case of MRS in a male adolescent. We also reviewed the previously 28 reported cases of MRS, collected from inception up to September 2022. RESULTS: MRS is characterized by aseptic meningitis and urinary retention. The mean length of the interval between the onset of the neurological signs and the urinary retention was 6.4 days. In most cases, no pathogens were isolated in cerebrospinal fluid, except for 6 cases in which Herpesviruses were detected. The urodynamic study resulted in a detrusor underactivity, with a mean period for urination recovery of 4.5 weeks, regardless of therapies. DISCUSSION: Neurophysiological studies and electromyographic examination are not pathological, distinguishing MRS from polyneuropathies. Although there are no encephalitic symptoms or signs, and the magnetic resonance is often normal, MRS may represent a mild form of acute disseminated encephalomyelitis, without radiological detectable medullary involvement, due to the prompt use of steroids. It is believed that MRS is a self-limited disease, and no evidence suggests the effectiveness of steroids, antibiotics, and antiviral treatment in its clinical course.

Malaria is not endemic in Italy, however every year about 600-700 imported cases are detected in people born or living in Italy who return from a stay in their country of origin (visiting friends and relatives - VFR). Children account for 20% of this population and they have an higher risk of severe disease. Socio-economic problems and deficiencies in the doctor-patient relationship often lead to a lack of awareness of the importance of prophylaxis, making the category of VFRs at increased risk of disease. The aim of this study is to analyze the characteristics of pediatric imported malaria, with a specific focus on prevention and risk factors for severe malaria. All malaria cases diagnosed from 2007 to 2019 in Ospedale Infantile Regina Margherita in Turin were retrospectively observed. Epidemiological and clinical data were described. A total of 72 patients were reported: 98.6% had African origins and 73.6% traveled as VFRs. Plasmodium falciparum was the species most commonly isolated (94.4%). Twenty-four patients (33.3%) underwent chemoprophylaxis and never appropriately. Patients not undergoing prophylaxis and those undergoing incomplete prophylaxis showed not statistically significant difference in term of disease severity (p = 0.26). Nineteen cases were considered severe, including 3 with cerebral malaria. High levels of parasitemia were statistically significantly correlated with severe anemia (p = 0.049) and severe thrombocytopenia (p = 0.036). In 25% of cases the first diagnosis was incorrect. The therapeutic use of artemisinin derivatives has resulted in a significant shortening of the parasitemia clearance time compared to the use of other drugs (p < 0.001). Families have to be educated about the serious implications of a malaria infection and the importance of a correct and complete prophylaxis. Clinicians should always consider malaria in the differential diagnoses in patients with fever and a history of a recent travel to an endemic area. Prompt diagnosis and use of appropriate drugs, according to the latest guidelines, could guarantee a better outcome for patients.

Children with the new coronavirus disease 2019 (COVID-19) have milder symptoms and a better prognosis than adult patients. Several investigations assessed type I, II, and III interferon (IFN) signatures in SARS-CoV-2 infected adults, however no data are available for pediatric patients. TRIM28 and SETDB1 regulate the transcription of multiple genes involved in the immune response as well as of human endogenous retroviruses (HERVs). Exogenous viral infections can trigger the activation of HERVs, which in turn can induce inflammatory and immune reactions. Despite the potential cross-talks between SARS-CoV-2 infection and TRIM28, SETDB1, and HERVs, information on their expressions in COVID-19 patients is lacking. We assessed, through a PCR real time Taqman amplification assay, the transcription levels of six IFN-I stimulated genes, IFN-II and three of its sensitive genes, three IFN-lIIs, as well as of TRIM28, SETDB1, pol genes of HERV-H, -K, and -W families, and of env genes of Syncytin (SYN)1, SYN2, and multiple sclerosis-associated retrovirus (MRSV) in peripheral blood from COVID-19 children and in control uninfected subjects. Higher expression levels of IFN-I and IFN-II inducible genes were observed in 36 COVID-19 children with mild or moderate disease as compared to uninfected controls, whereas their concentrations decreased in 17 children with severe disease and in 11 with multisystem inflammatory syndrome (MIS-C). Similar findings were found for the expression of TRIM-28, SETDB1, and every HERV gene. Positive correlations emerged between the transcriptional levels of type I and II IFNs, TRIM28, SETDB1, and HERVs in COVID-19 patients. IFN-III expressions were comparable in each group of subjects. This preserved induction of IFN-λs could contribute to the better control of the infection in children as compared to adults, in whom IFN-III deficiency has been reported. The upregulation of IFN-I, IFN-II, TRIM28, SETDB1, and HERVs in children with mild symptoms, their declines in severe cases or with MIS-C, and the positive correlations of their transcription in SARS-CoV-2-infected children suggest that they may play important roles in conditioning the evolution of the infection.

Antimicrobial resistance is one of the most relevant threats in public health worldwide. Strategies as antimicrobial stewardship programs, aiming to preserve our antibiotic armamentarium, have been implemented since 2007 in adult and paediatric patients. We aim to describe the first experience of a paediatric antimicrobial stewardship program. We conducted a retrospective observational study in a tertiary care children's hospital. A team composed of a microbiologist, an infectious diseases physician, and a paediatrician led the project. All positive blood and cerebrospinal fluid cultures and other biological samples yielding multi-drug-resistant bacteria were collected and reviewed through a prospective-audit-with-feedback strategy. We recorded patient characteristics and worth monitoring prescribed antibiotics. The antimicrobial stewardship audit could end in intervention (step-up/step-down and broadening/narrowing) or recommendation(s). We then checked out wards staff compliance. The team performed 192 interventions out of 584 reviews, mostly suggesting discontinuation of antibiotics (in 76.0% of cases and 39.7% of running molecules). The antibiotic spectrum was more likely tapered than expanded (p < 0.0001), and we ordered more narrow-spectrum antibiotic molecules than local medical staff straightaway did (p = 0.0113). Interventions were most likely needed in case of documented infections (p < 0.0001) and in surgical patients (p = 0.0002). In 85.9% of interventions, ward teams fully agreed with our argument. This study demonstrated an antimicrobial stewardship program to be a suitable method for improving the appropriateness of antimicrobial use in hospitalized children.

BACKGROUND: Multiple investigators have described an increased incidence of thromboembolic events in SARS-CoV-2-infected individuals. Data concerning hemostatic complications in children hospitalized for COVID-19/multisystem inflammatory syndrome in children (MIS-C) are scant. OBJECTIVES: To share our experience in managing SARS-CoV-2-associated pro-coagulant state in hospitalized children. METHODS: D-dimer values were recorded at diagnosis in children hospitalized for SARS-CoV-2-related manifestations. In moderately to critically ill patients and MIS-C cases, coagulation and inflammatory markers were checked at multiple time points and median results were compared. Pro-thrombotic risk factors were appraised for each child and thromboprophylaxis was started in selected cases. RESULTS: Thirty-five patients were prospectively enrolled. D-dimer values did not discriminate COVID-19 of differing severity, whereas were markedly different between the COVID-19 and the MIS-C cohorts. In both cohorts, D-dimer and C-reactive protein levels increased upon clinical worsening but were not accompanied by decreased fibrinogen or platelet values, with all parameters returning to normal upon disease resolution. Six patients had multiple thrombotic risk factors and were started on pharmacological thromboprophylaxis. No deaths or thrombotic or bleeding complications occurred. CONCLUSIONS: COVID-19 pediatric patients show mildly altered coagulation and inflammatory parameters; on the other hand, MIS-C cases showed laboratory signs of an inflammatory driven pro-coagulant status. Universal anticoagulant prophylaxis in hospitalized children with SARS-CoV-2-related manifestations is not warranted, but may be offered to patients with other pro-thrombotic risk factors in the context of a multi-modal therapeutic approach.

BACKGROUND: Mild encephalitis/encephalopathy with a reversible splenial lesion (MERS) is a clinical-radiological syndrome that can be related to infectious and non-infectious conditions. The most prominent neurological symptoms are disturbance of consciousness, abnormal speech, delirious behavior, seizures, muscle weakness, ophthalmoplegia, facial nerve paralysis and headache. Here we report the case of a child with MERS presenting with the unusual symptom of bilateral transient blindness. CASE PRESENTATION: A 4-year-old female patient, with a history of fever, abdominal pain, loss of appetite and cough lasted for a few days, experienced 3 episodes of transient bilateral loss of vision with difficulty in walking. Her physical examination showed absence of focal neurological and meningeal irritation signs, although responsiveness was slightly impaired. The ophthalmologic evaluation, including a fundus oculi examination, was negative. The electroencephalogram showed slow activity in the temporo-occipital regions, more evident in the right hemisphere. A lumbar puncture was performed and cerebrospinal fluid analysis revealed normal glycorrhachia, cell counts, protein levels and IgG index. Magnetic resonance imaging of the brain showed a signal alteration in the splenium of the corpus callosum, without contrast enhancement. This finding was suggestive of a reversible cytotoxic lesion. Empiric antiviral treatment with acyclovir and intravenous dexamethasone was initiated. Polymerase chain reaction search for neurotropic viral nucleic acid sequences in the cerebrospinal fluid was negative, while a low number of HHV-6 DNA copies was detected in the blood. Electroencephalograms were repeated in the following days, showing a progressive normalization of the pattern. The child was discharged without symptoms after 10 days of treatment with oral corticosteroids. After 40 days, brain magnetic resonance imaging showed a complete normalization of the signal alteration in the splenium of the corpus callosum. CONCLUSION: Transient blindness was reported as an initial symptom of MERS in a few children. To date, there is no evidence of effective treatment methods. Nonetheless, MERS diagnosis provides pediatricians with valuable prognostic information in order to reassure patients and their families about the good outcome of this disease.

Little is known about the sequelae of SARS-CoV-2 infection in children. In a COVID-19 dedicated clinic, we followed-up for 4 months 25 children previously hospitalized for COVID-19, performing clinical, laboratory, and lung ultrasound evaluation. Mid-term sequelae were rarely observed in our COVID-19 children's cohort.

Ceftolozane-tazobactam is a novel fifth-generation cephalosporin/ß-lactamase inhibitor combination recently approved for treatment of both complicated intra-abdominal and urinary tract infections in adults. Considering its potent bactericidal activity against Pseudomonas aeruginosa, it might represent an important option also for treating children with exacerbations of cystic fibrosis due to Pseudomonas aeruginosa when other alternative treatments have been exhausted. We hereby review available data on the use of ceftolozane-tazobactam in children, focusing on cystic fibrosis.

Pediatric neck masses are a common occurrence and often represent a diagnostic challenge. The primary aim of this retrospective study was to evaluate the clinical and radiological features of neck masses in children and how they can drive diagnosis. The secondary aim was to create a diagnostic algorithm based on clinical features. We evaluated 190 children with neck masses who needed hospitalization. Clinical data and imaging findings were collected. The patients were divided into six groups: congenital/developmental lesions, tumors, acute and subacute lymphadenopathies, chronic nonspecific lymphadenopathies, cat-scratch disease, and mycobacteriosis. Reactive lymphadenopathies were observed in the majority of cases (65.8%). Congenital/developmental cysts were present in 28.9%, while 5.3% had a tumor. A lower mean age was observed for acute/subacute lymphadenopathies and mycobacteriosis. Fever and a painful mass were typical of acute/subacute lymphadenopaties and cat-scratch disease. A hard and fixed mass was not only typical of tumors. Concerning imaging findings, multiple lymph nodes at the same level was mainly observed in mycobacteriosis, while bilateral lymph node enlargement and colliquation were present in lymphadenopathies.Conclusion:A complete and adequate clinical assessment should be the basis for every diagnostic and therapeutic choice in children with neck masses. What is Known: ⢠Pediatric neck masses are a common occurrence and often represent a diagnostic challenge. ⢠Clinical features, serological exams and imaging findings should drive the physician to an appropriate diagnostic hypothesis. What is New: ⢠A lower mean age was observed for acute/subacute lymphadenopathies and mycobacteriosis. ⢠A hard and fixed mass was not only typical of tumors. ⢠Multiple lymph nodes at the same level were mainly observed in mycobacteriosis, while bilateral lymph node enlargement and colliquation were present in nonspecific lymphadenopathies.

BACKGROUND: Malnutrition constitutes one of the major public health challenges throughout the developing world. Urban poverty and malnutrition have been on the rise, with an increased rate of morbidity. We herein explore the relationship between infections and nutritional status and the related association with hygienic conditions as risk of infection in children residing in the slums of Nairobi. METHODS: Case-control study based on a secondary analysis of quantitative data collected from a cluster randomized trial carried out in two slums of Nairobi. The following information about resident children were selected: babies' anthropometric measurements, related life conditions, data on infant-feeding practices, food security, hygiene, immunization coverage and morbidity were collected and updated with structured questionnaires until 12 months of life. Prevalence of malnutrition was calculated, then both bivariate and multivariate analysis were used to explore the relationship between malnutrition and its determinants. RESULTS: The study involved a total of 1119 babies registered at birth (51.28% male and 48.03% female infants). Overall the prevalence of malnutrition was high, with 26.3% of the children being stunted, 6.3% wasted and 13.16% underweight. Prevalence of wasting was higher in the first months of life, while in older children more case of stunting and underweight were captured. Wasted infants were significantly associated with common childhood illnesses: with cough and rapid breathing as well as with diarrhea (p-value< 0.05). Stunting was associated with hygienic conditions (p-value< 0.05 in households that did not perform any water treatment and for children that had a toilet within the house compound), immunization program and low-birth-weight. Moreover, regression analysis showed that significant determinants of stunting were sex and feeding practices. Underweight was significantly associated with socio-demographic factors. CONCLUSIONS: In the specific environment where the study was conducted acute malnutrition is correlated with acute infections, while chronic malnutrition is more influenced by WASH conditions. Therefore, our findings suggest that one cannot separate infection and its risk factors as determinants of the whole malnutrition burden.
