Toxic Shock Syndrome: Eighteen Years of Experience in a Pediatric Intensive Care Unit.

Introduction Toxic shock syndrome (TSS) is a life-threatening disease usually caused by a Staphylococcus aureus or group Aß-hemolytic Streptococcus infection. Methods In this retrospective study, we included patients with TSS admitted to a tertiary hospital's pediatric intensive care unit (PICU) over the last 18 years. We compared the staphylococcal TSS (Staph-TSS) and streptococcal TSS (Strep-TSS) groups. Results We included 17 patients (64.7% male), with a median age of 6.1 years (3.0 years for streptococcal TSS versus 13.3 years for staphylococcal TSS, p = 0.040), a median of 3.0 days from symptom onset to diagnosis, and a median of 6.0 days of hospitalization. Ten patients met the Centers for Disease Control and Prevention (CDC) criteria for staphylococcal TSS (one menstrual-related) and seven met the criteria for streptococcal TSS (four of them occurring since the COVID-19 pandemic was declared). Fifteen patients had identified risk factors, primarily cutaneous lesions (29.4%). In 15 patients, at least three organs or systems were affected, with fever, rash, and hypotension as universal findings. Mucous membrane hyperemia was present in 16 patients, gastrointestinal symptoms in 14 patients, and desquamation in nine. Muscular involvement was present in seven patients, all with staphylococcal TSS (p = 0.010). All patients received two or more antibiotics, including a protein synthesis inhibitor (except for one), and required fluid resuscitation and vasoactive amines (median three days). Six patients needed invasive mechanical ventilation (median seven days). Albumin infusion was necessary in six patients, significantly more frequently in patients with streptococcal TSS (p = 0.035). Two patients with staphylococcal TSS died, while the seven patients with streptococcal TSS survived hospital discharge. There were no recurrent cases. Conclusions Our study revealed TSS severity and multiorgan involvement, emphasizing the importance of early diagnosis and intervention. Risk factors were prevalent, and we noted an increased frequency of group A streptococcal (GAS) TSS post-COVID-19 pandemic.

Acute Fulminant Cerebral Edema in a Child With Suspected Meningoencephalitis.

Acute fulminant cerebral edema (AFCE) is a recently identified encephalitis type associated with significant morbimortality. Described as rare, limited data exists on its early detection and treatment. This paper describes a case of AFCE that progressed to unresponsive intracranial hypertension. A previously healthy four-year-old boy presented with fever, myalgias, and neurological symptoms. Diagnostic assessments showed cerebrospinal fluid abnormalities, and despite medical interventions, his condition deteriorated rapidly and developed severe cerebral edema and herniation within 24 hours. A decompressive craniectomy was attempted to decrease intracranial pressure, without success. This case emphasizes the urgency of early AFCE recognition and effective management strategies given its severe prognosis, aiming to improve understanding and spur further research.

Posterior Reversible Encephalopathy Syndrome in a Pediatric Intensive Care Unit: A Case Series.

Posterior reversible encephalopathy syndrome (PRES) is a reversible clinical-radiographic abnormality. It is characterized by headache, altered consciousness, seizures, and visual disruption, in addition to characteristic white matter edema lesions in the parieto-occipital areas of the brain. Early detection and treatment are crucial to prevent irreversible damage. This paper presents the cases of three patients with PRES with concurrent diagnoses of glomerulonephritis, Guillain-Barré syndrome, and sickle cell disease. All patients experienced systemic hypertension, seizures, and altered consciousness. All patients were admitted to intensive care for decreased level of awareness or status epilepticus requiring invasive mechanical ventilation. Anticonvulsants and antihypertensive therapy were essential. No chronic complications were recorded.

Use of recombinant human deoxyribonuclease in pediatric intensive care unit - a single-center experience.

OBJECTIVE: Dornase alfa (rhDNase) reduces the viscosity of purulent sputum in the lungs. The use in patients with cystic fibrosis (CF) is proven. However, the evidence of its applicability to other conditions is limited. This study aims to present the authors' experience with the use of rhDNase in non-CF patients admitted to the Pediatric Intensive Care Unit (PICU). At the study center, rhDNase was used during flexible bronchoscopies in 24 cases, of which 20 (83%) had atelectasis and seven (29%) were admitted to PICU. Four patients (57%) were on invasive mechanical ventilation (MV). CASE DESCRIPTION: Two cases of daily rhDNase administration at PICU are presented: patient A was an 8-year-old boy admitted with septic shock and acute respiratory distress syndrome (ARDS). The patient required mechanical ventilation with aggressive settings and experienced several clinical complications. On D50, he started rhDNase treatment with an improvement in FiO2, PaCO2 and PaO2/FiO2 ratio according to radiologic findings. He was extubated on D23 of treatment.Patient B was a 17-month-old girl admitted with a convulsive status epilepticus who experienced respiratory complications (infectious and barotrauma) with ARDS, requiring aggressive ventilation. She initiated rhDNase treatment on D60. During the treatment an improvement in FiO2, PaO2/FiO2 ratio and a tendency of PaCO2 decrease were found. She had radiological improvement. No complications were described. COMMENTS: RhDNase may be a helpful and safe tool to use in PICU prolonged intubated patients with ventilator-induced lung injury. Further studies are needed to assess and propose valid indications.

Valorization of traditional foods: nutritional and bioactive properties of Cicer arietinum L. and Lathyrus sativus L. pulses.

BACKGROUND: The use of traditional foods can enrich our diet, perpetuating important elements of local knowledge and cultural inheritance. Raw, soaked and cooked samples of two Fabaceae species (Cicer arietinum L. and Lathyrus sativus L.) were characterized regarding nutritional and bioactive properties. RESULTS: L. sativus gave the highest carbohydrate, protein, ash, saturated fatty acid and polyunsaturated fatty acid content, and lowest fat and energy value. Furthermore, it also showed the highest concentration of flavonoids and antioxidant activity. Cicer arietinum gave the highest concentration of sugars, organic acids and tocopherols. The soaking process did not significantly affect macronutrients, but cooking (boiling) decreased protein, ash, sugars and organic acids, and increased carbohydrates, fat, tocopherols, bioactive compounds and antioxidant activity. No differences were obtained for fatty acid composition. CONCLUSION: The present study highlights the nutritional profile and bioactive properties of these agricultural varieties of C. arietinum and L. sativus pulses, and valorizes their traditional consumption and the use in modern diets.
