Brain magnetic resonance imaging findings in patients with mucopolysaccharidosis VI.

Introduction: Mucopolysaccharidosis type VI (MPS VI) is a rare lysosomal storage disorder caused by the deficient activity of N-acetylgalactosamine 4-sulfatase. MPS VI is usually considered as not being associated with mental retardation.

Aims/methods: The main objective of the present study was to describe brain magnetic resonance imaging (MRI) findings and their correlation with clinical and biochemical findings in MPS VI patients.

Intrathyroidal thymic tissue mimicking a thyroid nodule in a 4-year-old child.

A 4 year-old girl was referred for CT of her neck for suspected submental lymphadenopathy and was found to have an incidental low-attenuation thyroid mass. Subsequent thyroid ultrasound showed a heterogeneous thyroid mass with punctate areas of increased echogenicity. Cytologic examination was consistent with ectopic intrathyroidal thymic nodule.

Morphometric differences in the Heschl's gyrus of hearing impaired and normal hearing infants.

This study investigates the morphometry of Heschl's gyrus and its included primary auditory cortex (PAC) in hearing impaired (HI) and normal hearing (NH) infants. Fourty-two infants, age 8-19 months, with NH (n = 26) or hearing impairment (n = 16) were studied using high-resolution 3D magnetic resonance imaging. Gray matter (GM) and white matter (WM) volumes were obtained using software for automatic brain imaging segmentation to estimate the volume of each tissue within manually defined regions for the anterior portion of Heschl's gyrus (aHG) in each individual subject, transformed to an infant brain template space.

Risk factors for cardiovascular disease ten years after preeclampsia.

Context And Objective: Preeclampsia is a gestational disease that occurs mainly among nulliparous women after the 20th week of gestation, and frequently close to delivery. The effects of preeclampsia on women's blood pressure over the long term are still controversial. Patients with recurrent preeclampsia or preeclampsia in the early stages of pregnancy appear to present higher risk of hypertension.

[Bronchoscopic removal of foreign body from airway through tracheotomy or tracheostomy].

Objective: Most foreign bodies in the airway are removed by respiratory endoscopy. Rarely, the removal of the foreign body has to be performed through endoscopic control by tracheotomy or tracheostomy. This article reports three cases of foreign body removal in children performed by tracheal opening.
