Natural history and mid-term neurodevelopmental outcome of fetuses with isolated mild ventriculomegaly diagnosed in the second half of pregnancy.

INTRODUCTION: Prenatal diagnosis and counseling of isolated ventriculomegaly (VM) represent a considerable challenge. We aimed to analyze the intrauterine evolution, associated anomalies, and neurodevelopmental outcome using the Battelle Development Inventory (BDI) of fetuses with an initial diagnosis of isolated mild VM. MATERIAL AND METHODS: Retrospective cohort study of fetuses diagnosed with mild isolated VM (10 -12 mm) between 2012 and 2016 in a tertiary hospital. In 2018, parents were invited to complete the structured BDI test for the neurodevelopmental evaluation of their children in five domains (personal-social skills, adaptive behavior, psychomotor ability, communication, and cognition). Results exceeding two standard deviations were considered abnormal and referred to an expert neuropediatrician. RESULTS: We identified 43 cases of mild isolated VM. In 5 (11%), structural abnormalities were detected during prenatal follow-up, being related to non-regressive forms (p = .01) and bilateral VM (p = .04). The BDI test was completed by 19/43 (44%). The global score was abnormal in 10/19 (53%). Of them, the neuropediatrician confirmed a neurodevelopmental delay solely in 3 cases that had already been diagnosed with neurological disorders. The most affected domains were gross motor skills (63%), personal-social (63%), and adaptive domains (47%). Communicative and cognitive areas were abnormal in 26% of cases. CONCLUSION: In fetuses with isolated mild VM detected in the second half of pregnancy, 53% had an abnormal BDI test at 2-6 years, but a neurological disorder was only confirmed in the 30% of them.

Tuberculosis screening after detection of a case in a paediatric haemato-oncology unit in a low prevalence country.

BACKGROUND: There are no guidelines to screen haemato-oncologic children when a tuberculosis (TB) outbreak is suspected. METHODS: After exposition to an adult with active TB, children exposed from a haemato-oncology unit were screened according to immunosuppression status and time of exposure. Until an evaluation after 8-12 weeks from last exposure, isoniazid was indicated to those with negative initial work-up. RESULTS: After 210 interventions, we detected a case of pulmonary TB, and another with latent TB infection. Pulmonary findings and treatment approach were challenging in some patients. CONCLUSIONS: The TB screening of oncologic children required a multidisciplinary approach, and clinicians managed challenging situations.

Antecedentes: No existen pautas para el cribado de niños hematooncológicos cuando se sospecha de un brote de tuberculosis (TB). Métodos: Después de la exposición a un adulto con TB activa, se evaluó a los niños expuestos de una unidad de hematooncología según el estado de inmunosupresión y el tiempo de exposición. Hasta una evaluación después de ocho a12 semanas desde la última exposición, se indicó isoniazida para aquellos con un proceso inicial negativo. Resultados: Tras 210 intervenciones se detectó un caso de tuberculosis pulmonar y otro con infección por TB latente. Los hallazgos pulmonares y el método de tratamiento fueron un desafío en algunos pacientes. Conclusiones: El cribado de TB en niños oncológicos requirió un método multidisciplinario y los médicos manejaron situaciones complejas.(AU)

Estimation of gestational age in neonates using clavicular-pubis length on routine chest-abdomen radiographs.

BACKGROUND: Neonatal diseases differ depending on gestational age and weight. In the setting of an emergency in the neonatal intensive care unit (NICU), relevant clinical information is often not available when the first neonatal radiograph is obtained. When reading an initial chest-abdomen radiograph, the paediatric radiologist needs gestational age data for best radiologic practice. A transverse diameter of the chest has been previously described to estimate gestational age (GA). OBJECTIVES: To determine the strength of the correlation between GA/weight and clavicular-pubis length (CPL) on admission radiographs; to obtain a quadratic formula based on the correlation of CPL with GA and to demonstrate if a more simplified formula used by our group works as efficiently as the formula provided by the regression analysis. MATERIALS AND METHODS: A retrospective study was approved by the institutional review board and informed consent was waived. The length from the medial aspect of the clavicle to the pubic bone was measured on the initial portable chest-abdomen radiographs of 260 patients admitted to the NICU in 2016. Regression analysis was performed to investigate the association between CPL and GA/birth weight. RESULTS: One hundred eleven females and 149 males with GA between 23 and 42 weeks were evaluated. CPL was statistically associated with both GA (P<0,01) and birth weight. The estimation can be expressed with an equation of the model: GA (weeks) = (CPL in cm - 1.98)/0.42. A simplified formula: GA (weeks) = (CPL in cm) ×2+2, strongly correlates with the equation model. CONCLUSION: In patients in whom it is not known, GA can be estimated by measuring the length between medial clavicle and symphysis pubis using the formulae we propose.
