Anatomy of the olfactory mucosa.

The classic notion that humans are microsmatic animals was born from comparative anatomy studies showing the reduction in the size of both the olfactory bulbs and the limbic brain relative to the whole brain. However, the human olfactory system contains a number of neurons comparable to that of most other mammals, and humans have exquisite olfactory abilities. Major advances in molecular and genetic research have resulted in the identification of extremely large gene families that express receptors for sensing odors.

[Capillary hemangioma of the middle ear: a case report].

Capillary hemangiomas are considered benign vascular tumours. Two-thirds of hemangiomas occur in the head and neck region. They commonly originate from the vascular networks around the geniculate ganglion.

Recovery from neurological sequelae secondary to oncological brain surgery in an adult growth hormone-deficient patient after growth hormone treatment.

Objective: To report an unusual case of significant neurological recovery in a 26-year-old growth hormone-deficient female patient with significant neurological sequelae resulting from brain surgery at 11 years of age.

Design: Case report.

Results: Most of the neurological sequelae present at admission recovered after 8 months of combined growth hormone administration and kinesitherapy/speech therapy.

Paraganglioma of the thyroid gland: a rare entity.

Paragangliomas are neuroendocrine tumors. The thyroid gland is one of the anatomic sites in which paraganglia are not normally located and are exceptionally rare. We report a case of a 36-year-old Hispanic woman with a soft mass measuring about 30 mm in the right thyroid lobe.
