Oral treatment with esomeprazole 0.25 mg/kg and 1 mg/kg was well tolerated and provided dose-related acid suppression, dose-related exposure to esomeprazole, and decreased esophageal acid exposure in infants 1-24 months old with GERD.
Meningioangiomatosis(MA) is a rare malformative or hamartomatous lesion involved in meninges and cortex. Although it was originally described in association with NF-2, recent studies have revealed that it occurs more frequently in sporadic form. The pathogenesis remains unclear. MA has distinct histological and biological features to meningioma(M) but their association(MA-M) isn’t unfrequent.Case reporta 12-years-old male was referred to our paediatric division for a history of headhache associated to malformative lesions shown at a first radiological investigation (CT and MRI) done in other hospital when he was 6 years old. At that time, neurosurgeons recommended follow up program. The lesions haven’t change over the years, as shown at the follow-ups, however the persistence of headhache induced the family to request a second opinion. Our physical examination showed mental retardation. He had no family history or stigmata of NF2 and no seizure’s history, electroencephalography didn’t show anomalies. A head CT scan showed the presence of a right hyperdense single mass with gyriform signal pattern and clumped intralesional calcifications. MRI showed an intracranial mass measuring 2x3 × 2.5 cm located in the right posterior frontal cortex. The lesion was hyperintense on T2-weighted imaging and weakly hypointense on T1W1, with ring-like enhancement. MRI confirmed gyriform signal pattern associated to focal areas of cortical fronto-parietal dysplasia. The diagnosis of MA was made. Our patient didn’t present seizure and the lesions appeared stable compared with the previous MRI so, in compliance with the neurosurgeon’s advice, we established a long-term follow up program in association with symptomatic therapy for headhache.MA occurs mainly in children and younger adults with male predisposition, suffering from intractable seizure and less frequently headhache. Atypical symptoms included vomiting, diabetes insipidus, facial weakness, muscle atrophy and pain. MA is a single lesion usually stable or slowly growing. Imaging diagnoses for MA is difficult. The most common finding on CT is a round, single, hypodense mass with varying degrees of calcification. On MRI, the lesions seem confined to the cortex. On T1WI, MA shows a low or iso-intense signal, on T2WI lesions are more frequently hyperintense, but sometimes they can be hypointense. A gyriform signal pattern is common on either CT or MRI, typical of sporadic MA and it’s helpful to distinguish pure MA from MA-M.
BackgroundPulmonary embolism (PE) is a potentially lethal condition. Although it’s usually manifested with severe symptoms causing right ventricular dysfunction or haemodynamic instability, in case of partial arterial obstruction it can be asymptomatic. Cancer patients are at high risk of thromboembolic complications. The use of contrast-enhanced computerised tomography for cancer staging has documented a high incidence of asymptomatic PE.Case presentationWe present a case of unsuspected PE in paediatric oncology patient. A 10-year-old boy presented with cervical and axillary lymph node swellings. No response to antibiotic therapy. Infectivological tests (mononucleosis, tuberculosis, toxoplasmosis…) were negative. Staging imaging revealed a positron emission tomography/computed tomography (PET-CT) avid anterior mediastinal lymph node. There weren’t liver, spleen and lung injury. Excisional biopsy of the lymph node was consistent with an anaplastic large cell lymphoma ALK+, t(2;5). After positioning of central venous catheter (CVC), the patient began treatment with chemotherapy with reduction of the lymphadenopathy. Subsequently, repositioning of CVC due to malfunction and displacement. After three months, he performed restaging; CT showed bilateral thromboembolism of the pulmonary arteries with partial obstruction. Echocardiogram showed a blood pressure’s increase in pulmonary artery (PAP 38 mmHg) but the child didn’t present respiratory and cardiac symptoms. Echo-color-doppler didn’t report venous thrombosis of the legs. Laboratory tests showed high platelet count. d-dimer levels and activated partial thromboplastin time value were increased. Inflammatory markers (C-reactive protein, erythrocyte sedimentation rate) were normal. The patient discontinued chemotherapy and started standard anticoagulant treatment. Two weeks later, CT and ultrasound controls displayed substantial reduction of the obstruction of the pulmonary arteries and decrease of PAP.ConclusionsThromboembolic complications are frequent in children with lymphoma. Often, routine thoracic MDCT examinations of paediatric oncology patients reveal cases of unsuspected PE. It is necessary to identify children at an increased risk for the development of PE to define an appropriate management. However, recent studies have showed that the lack of diagnosis and treatment do not have a negative influence on patient outcome.
