Visualisation of diverticula of the upper part of the alimentary tract; comparison of roentgenologic and endoscopic techniques.

Diverticula of the upper part of the alimentary tract, irrespective of their etiology, are frequently observed benign changes of the pharynx, oesophagus, stomach and duodenum. In the present work, patients of the II General Surgery Department of the Medical University of Lublin, with radiologically or endoscopically proved diverticula of the upper part of the alimentary tract, were examined. The presence of diverticula of such localisation was an indication for supplementary endoscopic or radiological examination. The localisation, size, diameter of the opening, mucosal relief of diverticula and its contiguity were checked and analysed. Our data suggest that both medical procedures are complementary to each other. All previously observed changes in diverticula of the thoracic part of the oesophagus and the infradiaphragm part of the alimentary tract were fully proved. The radiological examination gave a better view of Zenker's diverticulum, especially in short and obese patients. Sampling and better visualisation of the diverticula opening testify to the unquestionable superiority of endoscopy. However, precise evaluation by radiological process fully completes the diagnostic protocol. Both diagnostic procedures are usually supplemented by manometric examination of the oesophagus and superior and inferior oesophageal sphincters. This enables the accurate diverticula etiology to be stated.

Imaging diagnostic approach to tumours of ramus and angle of the mandible.

The abundance of up-to-date diagnostic equipment and imaging techniques makes it necessary to reconsider diagnostic approach to many maxillofacial disorders, including mandibular tumours, and to elaborate algorithms of radiological examinations allowing for the planning of a cost-effective treatment based on thorough diagnostics. The material was composed of 146 case records of 68 patients examined in the years 1995-2000 in the Medical University of Lublin. There were selected radiograms as well as the results of other imaging modalities of persons with clinically confirmed tumours of mandibular ramus or angle. In each case there were noted: the initial and the final diagnosis as well as the number and sequence of the performed diagnostic examinations. On the basis of the obtained results there was proposed a diagnostic algorithm in cases of mandibular angle and ramus tumours, which was presented in the form of a scheme. It was proved that conventional radiograms are still fundamental in initial selection of patients while other diagnostic imaging methods are indispensable in treatment planning.

The application of digital radiography and radiodensitometry in evaluation of chronic fibrous periapical changes of endodontically untreated teeth.

Lesions in hard tissues of teeth can be detected on radiograms only when there exists considerable decrease in mineralisation. By means of digital radiography the diagnostics of dental pathologies becomes more precise and objective. The aim of the paper was the radiodensitometric evaluation of chronic fibrous periapical changes. The material comprised 308 digital intraoral radiograms of teeth with periapical changes among which there were chosen the cases of clinically confirmed chronic fibrous periapical inflammations of endodontically untreated teeth. All radiograms were analysed in the Digora Soredex digital radiography system in gray scale, in full colour and using the tomosynthesis function. The linear measurements of root densities were carried out at the distance of 1 mm from radiological apices while the measurements of alveolar bone at the distance of 2 mm from it. Twenty-five teeth without evident periapical changes formed the control group. There were found significantly lower densities of roots and alveolar bone in the group of chronic fibrous periapical lesions in comparison with the control group. A characteristic feature of chronic fibrous periapical changes is the density of the root of an affected tooth that is higher than in acute inflammation and at the same time lower than in the control group. The radiodensitometry proved to be useful in evaluation of chronic fibrous periapical changes.

Early detection of potential impaction of permanent maxillary canines caused by resorption disorders of deciduous canines.

Maxillary canine impaction is an often-encountered dental anomaly as after the third molar it is the maxillary canine that is the most frequently impacted tooth. One of many factors causing impaction of maxillary canines is the presence of the persistent primary canine. The aim of the study was early evaluation of resorption of deciduous maxillary canines and an attempt at prediction of impaction or delayed eruption of their permanent counterparts as well as the possibility of their eruption in proper position in the dental arch. There were examined digital intraoral radiograms of 43 patients at the age from 8 to 11 years (44% boys, 56% girls). All the radiograms were taken using the Digora Soredex digital radiography system. There was observed the presence and degree of resorption of deciduous maxillary canines according to age and sex. It was evaluated whether a deciduous canine might be a mechanical obstacle for erupting the permanent tooth. It was concluded that although physiological resorption of deciduous maxillary canine begins at the age of 8, it is radiologically evident on intraoral digital X-rays taken at the age of 9-10 years. So the best time to assess a patient for potential resorption of primary canine and possibilities of eruption of its equivalent in proper position in dental arch is between the 9th and 10th year of age.

Primary adenocarcinoma of the jejunum--a case report.

A case of adenocarcinoma of jejunum is reported. Although survival figures in adenocarcinoma of the small bowel appear to correlate with early presentation, due to poor specificity of the symptoms a preoperative diagnosis is very seldom. Therefore, in order to improve the treatment outcome, the diagnosis must be done at an early stage. Thus there are discussed imaging modalities applied in diagnostics of this rare pathology.

Imaging diagnostics strategy in maxillary sinus neoplasms.

Malignant neoplasms of maxillary sinuses are a serious diagnostic and therapeutic challenge, so the objective of a clinician is the planning of a cost-effective strategy promptly leading to proper diagnosis and the onset of treatment. Thus the aim of the paper was the elaboration of diagnostic strategy in maxillary neoplasms. There were analyzed 163 case records of 78 patients with maxillofacial neoplasms. The number and sequence of the conventional radiograms as well as diagnostic imaging methods were registered. There was proposed an algorithm of application of imaging techniques in diagnostics of neoplasms of maxillary antra. It was found that conventional X-rays are still valuable in screening for sinus pathology and as indication of the necessity of performing other imaging examinations. Computed tomography and magnetic resonance are complementary in visualization of pathologic masses and bone tissue destruction.

Demographic structure of patients taking dental X-rays in the Lublin region.

Intraoral radiograms are the most often taken X-ray pictures in humans and the dose of radiation necessary for such radiogram is very low. However, there exists a considerable anxiousness in Polish society towards Roentgen radiation making patients avoid dental X-rays even when these are indispensable in dental treatment. The aim of the study was the evaluation of demographic structure of patients taking intraoral radiograms. The material consisted of 1,014 adults undergoing dental treatment, who had intraoral radiograms taken in the Department of Dental and Maxillofacial Radiology in 2000. After the informed consent the patients filled an anonymous questionnaire of standardised interview. The collected records were analyzed statistically and data such as age, sex, education, place of residence, employment and income were considered. The demographic structure of population of patients who had intraoral radiograms taken in the course of dental treatment differs considerably from the structure of the general population. These differences were marked especially when taking into account the level of education, employment and place of residence of the studied patients. Inhabitants of rural communities, people with lower level of education as well as older patients avoid taking dental radiograms irrationally fearing ionizing radiation. The economic factor is also important and influences the structure of patients in the domain of employment and income.
