RESUMO
A case of parasagittal meningioma causing subarachnoidal haemorrhage (SAH) is reported. Computed tomography (CT) was found negative in the patient with acute severe headache and haemorrhage was observed on cerebrospinal fluid (CSF) examination. Digital subtraction angiography (DSA) showed an avascular space over the convexity and Magnetic resonance imaging (MRI) revealed the tumour. The importance of MRI for the detection of underlying pathology in SAH with unknown aetiology is emphasised.

Wilms' tumor is a rare malignancy of kidney in adults. It usually cannot be differentiated from other renal masses preoperatively. This is a presentation of a case of adult Wilms' tumor who developed spontaneous hemorrhage during radiological evaluation. As tumor rupture can change the stage of the tumor and alter the prognosis of the patient, urgent work-up and treatment is advised.

The differences between breast milk and infant formulas have been a popular subject of many recent studies. Most concern the chemical and biological characteristics of breast milk and infant formulas, but little work has been done about hemodynamic changes in the splanchnic circulation. In term neonates (n = 22) we evaluated the effect of breast milk, adapted cow's milk formula, and nucleotide supplemented cow's milk formula on intestinal blood flow. To determine the blood flow velocity and estimate volume flow, pulsed Doppler ultrasound of the superior mesenteric artery (SMA) was performed prefeeding and 15, 45, and 90 minutes following feeding. When pre- and postprandial blood flow features of babies were compared among in their groups according to nutrition post prandial blood flow velocity and volume flow were increased significantly over baseline in all three groups. While there was no significant difference between the postprandial blood flow parameters of the breast milk and adapted cow's milk formula-fed groups, the nucleotide supplemented cow's milk formula-fed group had significantly higher postprandial blood flow velocity and volume flow.

To assess tibialis posterior tendon (TPT) pathology, we investigated 27 feet with the accessory navicular bone and 22 normal feet by MRI. We found two major anatomical differences in the feet with the accessory navicular bone; the TPT directly inserted in the accessory navicular bone, without any continuity to the sole of the foot or with a slip, less than 1 mm in thickness, and there was a mass with the density of fibrocartilage tissue, between the tendon and the bone in 20/27 feet. These abnormalities were not detected in the control group. 3 patients in the study group were operated on and the MRI findings were confirmed. These findings suggest that patients with the accessory navicular bone and flatfoot should be examined by MRI for insertion abnormalities of the TPT.
