The condition of the oral cavity in patients receiving chronic steroid therapy - practical remarks.

A significant increase is currently being observed in the number of patients hospitalized due to respiratory system diseases, such as chronic obstructive pulmonary disease (COPD), and bronchial asthma with a predominantly allergic component. Treatment of COPD and bronchial asthma is mainly based on the use of beta-2-mimetics and glucocorticosteroids (GCS). However, the GCS inhalation therapy may be associated with developing a risk of various types of complications, which are especially manifested in the initial part of the respiratory system. In the paper the side effects resulting from the chronic use of inhaled GCS was presented with discussion how to reduce their negative effects. The negative side effects of chronic GCS therapy for the treatment of pulmonary diseases result mainly from their modifying effect on the proper functioning of the immune system, and on their generation of salivary secretion disorders. When using inhaled GCS, drugs deposit on the mucosa membrane of the throat and oral cavity, which promotes the development of candidiasis which accompanied by xerostomia leads to difficulty in swallowing and speaking. The reduced salivation promotes the development of caries disease due to the impairment of the physiological mechanism of tooth surface cleaning. Attention to proper oral hygiene is fundamental and an appropriate antifungal therapy is required. When conducting a physical examination, it is important to pay attention to those patients using inhaled steroids, especially on a chronic basis. This is because with careful clinical evaluation, the side effects of these drugs can be detected at an early stage and the appropriate treatment of their negative effects can be applied.

The course of the main septum in the sphenoid sinuses - evaluation before the FESS.

The purpose of this study was to determine the course of the main septum (MS) in the sphenoid sinuses in the adult population. Materials and Methods: 296 patients (147 females, 149 males), who did not present any pathology in the paranasal sinuses, were included in this retrospective analysis of the computed tomography (CT) scans. Spiral CT scanner (Siemens Somatom Sensation 16) was used in order to glean the images of the paranasal sinuses, using standard procedure, in the option Siemens CARE Dose 4D, without using any contrast medium. Secondary reconstructions of the sagittal and frontal planes were obtained using multi- plans reconstruction (MPR) tool after obtaining transverse planes in the first instance. R e s u l t s: The course of the MS changed the most often from the anterior to the posterior part of the sphenoid sinuses. Such situation took place in 83.78% of the patients, in 32.43% of whom a clear shift to the lateral side was noticed only in the posterior part of the MS: in 18.24% of the patients to the right side, and in 14.19% of the patients to the left side. In 17.57% of the patients the lateral shift was visible in both anterior and posterior parts of the septum, where in 9.46% of the patients it was from the left side to the right, whereas in 8.11% of the patients the shift took place from the right side to the left. The MS had the shape of the letter 'C' in 22.29% of the cases, and 11.82% had the typical shape of the letter 'C,' and in 10.47% of the patients it paralleled the inverted letter 'C' (upside down). Amongst the types of the MS shifting directions the rarest was the MS that resembled the letter 'S' - 11.48% of the patients. In 5.74% of the cases it looked like the typical letter 'S,' and in 5.74% of the cases it was similar to the inverted letter 'S.' Only 16.22% of the cases had the MS that did not change its course nor its shape and ran medially in the sagittal plane from the anterior to the posterior part of the sinuses. Conclusions: In furtherance of reducing the risk of problems occurring during a surgery in the paranasal sinuses, it is prudent to have a CT scan done in all the patients beforehand, due to the high prevalence of the anatomical variations in the sinuses.

Incorporation of the sphenoid sinuses' septum / septa in the carotid canal - evaluation before the FESS.

The purpose of the research was to define the frequency prevalence of the incorporation of sphenoid sinuses' septum / septa in the carotid canal of the adult population. MATERIALS AND METHODS: 296 computed tomography (CT) scans of the patients (147 females, 149 males), who did not present any pathology in the sphenoid sinuses, were evaluated in this retrospective analysis. Spiral CT scanner - Siemens Somatom Sensation 16 - was used to glean the medical images. Standard procedure applied in the option Siemens CARE Dose 4D. No contrast medium was administered. Multiplans reconstruction (MPR) tool was used in order to obtain frontal and sagittal planes from the transverse planes previously received. RESULTS: Bilateral incorporation of the main septum (MS) in the carotid canal was not present in any of the patients, whereas unilateral incorporation was noticed in 21.96% of the patients (17.68% females, 26.17% males). On the right side it occurred in 11.82% of cases (10.88% females, 12.75% males), and on the left side in 10.14% of cases (6.8% females, 13.42% males). Bilateral incorporation of the additional septum (AS) was found in 8.45% of the patients (4.08% females, 12.75% males), whereas unilateral incorporation was noted in 28.37% of the patients. It was seen on the right side in 11.82% of cases (12.93% females, 10.74% males), and on the left side in 16.55% cases (15.65% females, 17.45% males). The most common variant was the incorporation of only one of the septa (either the MS or the AS) in the wall of the carotid canal unilaterally. Such situation took place in 30.07% of the patients (29.25% females, 30.87% males). Incorporation of two septa on the same side was noticed in 4.39% of cases (4.08% females, 4.7% males), and incorporation of three septa in 0.34% of cases (0.7% males). CONCLUSIONS: The anatomy of the paranasal sinuses is varied to a great extent, hence performing a CT scan is crucial before the scheduled surgery, as it may lessen the unforeseeable surgical complications, that may result from the high prevalence of variants in the sinuses.

The height and type of the main septum in the sphenoid sinuses - evaluation before the fess.

The purpose of this study was to examine the height of the main septum (MS) in the sphenoid sinuses and its type, depending on the percentage prevalence of its tissue composition (osseous and membranous) in the adult population. Materials and Methods: A retrospective analysis of 296 computed tomography (CT) scans (147 females, 149 males) of the paranasal sinuses was conducted. The patients did not present any pathology in the sphenoid sinuses. The CT scans of the paranasal sinuses were carried out with a spiral CT scanner (Siemens Somatom Sensation 16) in a standard procedure, in the option Siemens CARE Dose 4D. No contrast medium was used. Having obtained the transversal planes, a secondary reconstruction tool (multiplans reconstruction - MPR) was used in furtherance of gleaning sagittal and frontal planes. R e s u l t s: In all cases, the height of the MS was measured by using a straight line running parallel to the course of the septum (when the MS was regarded as straight) or curved (when the MS was regarded as irregularly shaped). The average height of the MS was 2.1 ± 0.41 cm in the whole research group. Completely osseous MS was found in 32.77% of the patients. In 63.85% of them, the MS was partially membranous. The rarest was the MS which was not even partially ossified - a membranous type, that was observed in 3.38% of the patients. C o n c l u s i o n s: Variant anatomy of the paranasal sinuses may lead to complications encountered during a surgery, hence a CT scan is advised before the planned treatment.
