Morphology of tracheal scar after resection with CO2-laser and high-frequency cutting loop. A study in normal pigs.

In 6 pigs a bronchoscopical resection of the tracheal mucosa was performed using CO2-laser on one side, and an electric high-frequency cutting loop (ECL) on the other. The pigs were sacrificed 3 months later. On macroscopic examination the tracheal mucosa appeared almost normal on the laser-resected side, while severe deformation was seen after ECL treatment.

Familial centronuclear myopathy: a clinical and pathological study.

A congenital myotubular myopathy in a family is presented. An elderly woman, her daughter and her granddaughter showed the characteristic clinical and histological pattern of the disease. It is still a matter of debate whether the disease is of myopathic or neuropathic origin.

Nasal Schneiderian papillomas: a study of 83 cases.

Nasal Schneiderian papillomas are unique lesions involving the mucosa of the nasal cavity and paranasal sinuses. Most often epidermoid in histological appearance, they favour 2 sites: the septum and the lateral wall of the nasal cavity. The medical literature on these tumours contains a plethora of contradictions concerning the nomenclature and no less than 54 separate designations are used.
