Breast phantom for comparison X-ray and polarimetric optical tomography imaging.

Breast phantom made as combination of paraffin and INTRALIPID™ was tested by use of X-ray classical computed tomography and polarimetric optical tomography. The INTRALIPID™ is a liquid commonly used for simulation breast tissues optical properties but it is useless as X-ray phantom. During our tests we have observed that X-ray tomography allows to recognize a proper placement of INTRALIPID™ inclusions inside paraffin medium but we cannot distinguish density of INTRALIPID™ within each inclusions. On the other hand the polarimetric optical tomography allows to distinguish density of INTRALIPID™ (0%, 10%, 20%) in inclusions but with relatively low accuracy of their placement.

Tinnitus is a sound impression in one or both ears appearing without any acoustic impulses from the environment. It can be a morbid symptom coming either from different parts of the auditory path (from the external auditory meatus to the auditory area in the cerebral cortex) or other organs. Usually ear noise is accompanied by hypacusis. According to British Tinnitus Association one of ten people suffers from ear noises and about 35-45% of adults have come down with it. This number is still increasing. The older the patients is the more frequent the noises are, especially among women after 40 and men after 50 years old. Because of varying origin different therapy methods are applied (surgical, pharmacological, psychotherapy).

[Tinnitus. II.--treatment]. / Szumy uszne. Cz. 2--leczenie.

Because of varying origin different therapy of tinnitus methods are applied (surgical, pharmacological, psychotherapy). Treatment of objective tinnitus of vascular origin is usually surgical. It is similar as in the case of tinnitus of mechanical origin. The procedure of operating. Treatment of subjective tinnitus is much more complicated because of difficulties with determining of its occurence. We can separate morbus Ménière, otosclerosis, which require precise treatment. Apart from these disease treatment of subjective tinnitus is multidirectional. It may include pharmacological treatment, psychotherapy, surgical treatment and other methods.

[Head and neck lymphomas in the material of the ENT department of Municipal Hospital in Gdynia in 1977-1996]. / Chloniaki glowy i szyi w materiale Oddzialu Otolaryngologicznego Szpitala Miejskiego w Gdyni w latach 1977-1996.

The authors present data relating to patients with malignant lymphoma of the head and neck diagnosed at the ENT Department, Municipal Hospital in Gdynia, during the years 1977-1996. The material is analysed in relation to the sex and age of the patient and the localisation of tumour. Some cases are presented in detail depending on localisation or difficulties in diagnosis (lymphoma of the larynx and ethmoidal sinus).

The authors present a case of thyroid cancer manifestating itself as carotid body tumor. Fine needle biopsy performed twice and an arteriography suggested this diagnosis.
