No significant difference was found between the two groups. Recognition of these lesions antenatally would benefit patients by avoiding delay in making the diagnosis, which can lead to serious complications. CT was successful in accurately diagnosing and grading CCAM lesions.
We advocate that in the Chiari malformation type 1-syringomyelia complex with normal or small ventricles, patients presenting with isolated signs and symptoms of raised intracranial pressure alone can be safely and effectively managed with an electromagnetic-guided stereotactic endoscopic third ventriculostomy as a primary treatment option.
Background/Objective: Anterior spinal artery syndrome is an extremely rare cause of acute ischemic cord infarction in children. It is caused by hypoperfusion of the anterior spinal artery, leading to ischemia in the anterior two thirds of the spinal cord. The presentation is usually with an acute and painful myelopathy with impaired bladder and bowel control. Pain and temperature sensation below the lesion are lost, whereas vibration and position sense is intact because of the preservation of the posterior columns. Methods: Case report. Results: A 16-year-old girl with Down syndrome presented with urinary retention and acute complete flaccid paralysis of the legs with absent deep tendon and abdominal reflexes. Magnetic resonance imaging showed a signal abnormality in the anterior half of the thoracic cord from T5 to T12, consistent with anterior spinal artery infarction. Conclusions: Pediatricians should consider anterior spinal artery syndrome in the child who presents with acute, painful myelopathy. We summarize the etiology, neurological findings and outcomes of 19 children found in the literature with anterior spinal artery syndrome.
Genetic variants of small airways and interstitial pulmonary disease have not been comprehensively studied. This cluster of respiratory disorders usually manifests from early infancy (‘lung disease in utero’). In this study, 24 variants linked to these entities are described. The variants involved two genes associated with surfactant metabolism dysfunction (ABCA3 and CSF2RB), two with pulmonary fibrosis (MUC5B and SFTP), one with bronchiectasis (SCNN1B), and one with alpha-1-antitrypsin deficiency (SERPINA1). A nonsense variant, MUC5B:c.16861G > T, p.Glu5621*, was found in homozygous state in two siblings with severe respiratory disease from birth. One of the siblings also had heterozygous SFTPA1:c.675C > G, p.Asn225Lys, which resulted in a more severe respiratory disease. The sibling with only the homozygous MUC5B variant had lung biopsy, which showed alveolar simplification, interstitial fibrosis, intra-alveolar lipid-laden macrophages, and foci of foreign body giant cell reaction in distal airspaces. Two missense variants, MUC5B:c.14936 T > C, p.Ile4979Thr (rs201287218) and MUC5B:c.16738G > A, p.Gly5580Arg (rs776709402), were also found in compound heterozygous state in two siblings with severe respiratory disease from birth. Overall, the results emphasize the need for genetic studies for patients with complex respiratory problems. Identifying pathogenic variants, such as those presented here, assists in effective family counseling aimed at genetic prevention. In addition, results of genetic studies improve the clinical care and provide opportunities for participating in clinical trials, such as those involving molecularly-targeted therapies.
Background: Risks of diagnostic radiation have become more notable lately, particularly in young children with chronic medical conditions. This study reports on the cumulative radiation from chest radiographs in children with asthma. Its main purpose was to review our current practice and suggest minimizing the use of chest radiographs.Methods: The study was retrospective and conducted at a pediatric tertiary center. Eligibility criteria included children 2–15 y, admitted between January 2017 and December 2018 for asthma management.Results: Of the 643 children admitted as “asthma exacerbation,” 243 [40% females; age (mean ± SD) 5.4±3.3 y] met the study criteria for inclusion. Ninety-two (38%) children had a temperature of 38.8±0.7°C on the day of admission. Antibiotics were prescribed for 148 (61%) children, mainly for presumed pneumonia. Chest radiographs were requested for 214 (88%) children, mainly on the day of admission. Only 38 (18%) chest radiographs showed focal/multifocal pneumonia justifying antibiotic use. Significant predictors for requesting chest radiographs were antibiotic use for presumed pneumonia, lower oxygen saturation at presentation, and a requested blood culture. The rate of chest radiographs per year was negatively related to the child's age; the younger the child the higher the rate (model coefficient −0.259, P < 0.001). For children < 5 y, the rate of chest radiographs was 1.39 ± 1.21/y and radiation dose 0.028 ± 0.025 mSv/y. The corresponding rates for children ≥5 y were 0.78 ± 0.72/y and 0.008 ± 0.007 mSv/y, respectively (P < 0.001).Conclusion: Chest radiographs were commonly requested for children with asthma, especially younger children. Prospective studies are necessary to measure the impact of this practice on the children's health.
Subdural empyema complicating meningococcal meningitis is rare. We describe a case and 14 previously reported cases; all had persistent fever and 12 had seizures. Initial cerebrospinal fluid showed raised protein with low glucose values. Neuroimaging confirmed the diagnosis in all cases where undertaken. Ten children had neurosurgical intervention. Clinical outcome was available in 14 cases; a full recovery was reported in 10 and 1 child died.
In the United Arab Emirates, BCG (Bacillus Calmette-Guérin) is administered to all newborns. We present here a young infant with an inborn error of immunity (IEI) who developed fatal adverse events to this live-attenuated vaccine. This male infant received BCG (Serum Institute of India Pvt., Ltd., India) on Day 11 of life. On Day 25, he developed fever, followed by cervical lymphadenitis and bilateral otitis media with fluid drainage. On Day 118, he was admitted with severe hemophagocytic lymphohistiocytosis (HLH), and passed away on Day 145. The diagnostic exome sequencing test identified a hemizygous nonsense variant, NM_000397.3(CYBB):c.676C>T, p.Arg226* (rs137854592). Pathogenic variants of CYBB [cytochrome b(-245), beta subunit; Mendelian Inheritance in Man [MIM] accession code, 300481] are known to cause “immunodeficiency 34, mycobacteriosis, X-linked” (IMD34, MIM#300645) and “chronic granulomatous disease, X-linked” (CGDX, MIM#306400). The natural history of his illness is consistent with “X-linked recessive Mendelian susceptibility to mycobacterial disease (MSMD).” This entity is responsible for his BCG disease and is a likely trigger of his HLH. This disastrous event underlines the importance of developing worldwide policies that target BCG disease prevention, especially in communities with high prevalence of IEI. Moreover, screening for genetic causes of MSMD in the community could pave the way, at least partially, for scale-up of tuberculosis (TB) prevention.
Pregnancy in women with lupus nephritis is associated with increased risk of fetal and maternal complications. The risk of poor outcome is higher if there are signs of disease activity at conception. The presence of hypertension and anti-phospholipid antibodies worsens the prognosis. There are very few therapeutic options in view of the threat of various congenital anomalies and associated comorbidities. Mycofenolate mofetil (MMF) is contraindicated during pregnancy due to risk of congenital anomalies and fetal loss. This is a case of a woman with membranous lupus nephritis, who went into partial remission with rituximab and became pregnant while on maintenance therapy with MMF. Due to lack of alternative options, she continued to be given MMF. She had a successful outcome in spite of the presence of the poor prognostic factors. The baby had asymptomatic non-communicating duplication of the oesophagus, which has never been reported before in association with MMF during pregnancy.
