- Kawasaki disease in a five-month-old infantPublication . Maciel, Juliana; Meireles, Daniel; Magalhães, Mariana; Gonçalves, Sara; Ribeiro Fernandes, Sofia; Fernandes, Paula CristinaIntroduction: Kawasaki disease, an acute self-limited vasculitis of small and medium arteries of unknown etiology, is the leading cause of heart disease in children in most developed countries. If untreated, it can lead to coronary artery dilatation and aneurysm, placing patients at risk for coronary thrombosis, myocardial infarction, or sudden death. Case Report: A previously healthy five-month-old boy presented with a history of respiratory symptoms and fever, being admitted for respiratory syncytial virus bronchiolitis. He maintained fever for five days associated with progressive clinical worsening and sequential development of conjunctival injection, cracked lips, swelling of hands and feet, and polymorphous rash of the limbs. Diagnostic procedures showed increased levels of inflammatory markers, hyponatremia, hypoalbuminemia, sterile pyuria, and aseptic meningitis. Despite an initial normal echocardiogram, Kawasaki disease was suspected and the boy started intravenous immunoglobulin on the fifth day. On the seventh day, echocardiogram showed signs of pancarditis and mild coronary artery ectasia and acetylsalicylic acid was started. The boy was discharged, but eight days later echocardiogram revealed major and diffuse coronary artery ectasia in a follow-up consultation and he was readmitted to start corticosteroid therapy. After five months, the boy displayed normalization of cardiac changes, without further complications. Comments: Kawasaki disease below six months of age is rare and associated with a high risk of coronary artery aneurysm. It is important to recognize the clinical and laboratory criteria associated with this entity and start early treatment, avoiding cardiac complications.
- Pediatric idiopathic midgut volvulus and shock in the infantPublication . Maciel, Juliana; Santos, Ana Luísa; Marinho, Ana Sofia; Figueiredo, Susana; Araújo, Ana Rita; Morgado, Hélder; Banquart Leitão, José; Sarmento, Alzira; Ribeiro Fernandes, Sofia; Ferreira, Paula ReginaIntroduction: Intestinal volvulus is a surgical emergency in which a segment of the intestine twists over its mesenteric attachment, causing bowel obstruction. It usually presents with bilious vomiting and can progress to bowel necrosis and shock. Case Report: A 40-days-old male infant presented with acute onset irritability, bilious vomiting, abdominal distention, and hematochezia. He rapidly evolved to shock with metabolic acidosis and coagulopathy, requiring fluid resuscitation, vasoactive agents, and invasive mechanical ventilation. The patient was submitted to urgent laparotomy, confirming midgut volvulus without malrotation. Partial reperfusion of the affected midgut was achieved, with no resection initially performed, but 48 hours later he was re-evaluated and partial enterectomy for midgut necrosis was performed. Despite the condition´s severity, the patient had a good evolution with full recovery. Discussion: Bilious vomiting in the infant is highly suggestive of intestinal obstruction. The authors emphasize the presence of midgut volvulus without malrotation, complicated with bowel necrosis and shock.
- Posterior Reversible Encephalopathy Syndrome in a Pediatric Intensive Care Unit: A Case SeriesPublication . Teixeira, Beatriz; Gonçalves, Vera; Cardoso, Ana Lúcia; Ribeiro Fernandes, Sofia; Rocha, Liliana; Garrido, Cristina; Sarmento, AlziraPosterior 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.
