Background. Sinus lift with a simultaneous implant placement in the residual maxilla is a common technique used worldwide. Nevertheless, choosing an ideal grafting material remains an object of dispute. The use of an autologous blood-derived graft, known as platelet-rich fibrin (PRF), has not yet been recognized to be as good as xenografts and alloplastic materials. However, initial results have been promising.Objectives. To conduct a clinical and radiological comparison of implantation with a simultaneous sinus lift using xenograft or PRF clots. Materials and methods.Thirty sinus lifts with simultaneous implantation were conducted using a lateral window approach and the tent pole technique, with xenograft (group 1 (G 1 )) or PRF (group 2 (G 2 )) as a filling material. To be included in the study, patients must have had an alveolar ridge height of 4-5 mm, no signs of inflammatory processes, good oral hygiene, and no other grafting procedures performed in region of implant insertion. In each case, the measurements taken were probing pocket depth (PPD), height of keratinized tissue (HKT), clinical attachment level (CAL), recession depth/width (RD/RW), and, on panoramic X-rays, marginal bone loss (MBL), grafted sinus high (GSH), and bone gain (BG). Pre-and post-operative treatment was applied to reduce the chance of infection.Results. During the study, 30 implants (hydroxyapatite-coated implants manufactured by SGS -10 mm in length and 4.2 mm in diameter) were placed. The survival rate of implants in both groups was 100% with no implant mobility, pain, paresthesia, or inflammatory processes in the direct vicinity of the implants observed, except in 1 patient. After 36 months of follow-up, the radiological assessments for G 1 were: GSH 4.5 mm, MBL 0.46 mm and BG 4.53 mm; and for G 2 : 3.4 mm, 0.6 mm and 3.4 mm, respectively. Results of the clinical measurements were for G 1 : HKT after 36 months (HKT 36 ) 2.46 mm, CAL 0.47 mm and PPD 2 mm; and for G 2 : HKT 36 3. 13 mm, CAL 0.6 mm and PPD 2.07 mm. Conclusions.After 3 years of follow-up, the results of sinus lifting solely using PRF with simultaneous implantation were promising, especially in terms of soft tissue management. Therefore, PRF can be regarded as an alternative to previously used materials.
Objectives We had developed a method that can help detect and identify lymph nodes affected by the neoplastic process. Our group evaluated the fractal dimension (FD) and X-ray attenuation (XRA) of lymph nodes in HL and compared to their metabolic activity as measured by 18F-FDG-PET examination. Methods The training set included 72 lymph nodes from 31 consecutive patients, and the tested set of 71 lymph nodes from next 19 patients. The measurement of FD of each lymph node was performed before the start of therapy using original software. X-ray attenuation (XRA) expressed in HU (Hounsfield Units) from CT scans was compared with the metabolic activity of the lymphatic nodes, measured by 18F-FDG-PET examination. Results Significant differences were observed between XRA max and FD max values in assessing the PET(+) and PET(-) nodes. All nodes were scored from 0 to 2. The HUFRA test properly qualified 95% with a score of 2 and 0 points as PET(+) or PET(-).
Background. The aim of this work is to prepare a dental diagnostic standard that would enable us to distinguish patients with chronic odontogenic sinusitis (COS) from patients with sinusitis of other origin. We also wanted to determine a realistic number of COS in the Polish population.
The aim of this study was to investigate lung function in patients with gastro-esophageal reflux disease (GERD) who present respiratory symptoms suggestive of the possibility of co-morbid asthma. The study encompassed 20 patients (9 women and 11 men; age range from 11 to 68 years) diagnosed with GERD and presenting with chronic cough and other non-specific periodic respiratory complaints. The control group consisted of closely gender and age-matched 20 subjects without any gastrointestinal or respiratory symptoms. All patients and control subjects were tested for lung function, which encompassed spirometric and flow-volume variables. We found that none of the GERD patients had lung function abnormalities characteristic of asthma. There were, however, decreases in forced expired volume in 1 s, forced vital capacity, and in maximal instantaneous forced expiratory flows in the GERD patients compared with the healthy subjects. We conclude that cough accompanying GERD is unlikely to be associated with the presence of co-morbid asthma, but rather suggests a mild airway inflammation developing as a sequel of GERD. The corollary is that chronic cough should prompt physician's attention to consider diagnostic work-up toward the possibility of GERD.
The aim of this study was to analyse the results of exhaled nitric oxide examination in a group of patients with hyper-responsive-ness. The study was performed on a group of 297 children who underwent spirometry, examination of exhaled nitric oxide, skin prick test and stress probe in years 2010-2012 in Pulmonology and Allergy Centre in Karpacz. Mean age of patients was 11.86. Patients were divided into four groups: with diagnosed asthma, with bronchial hyper-responsiveness (BHR), with described asthma without BHR and a group with BHR without diagnosed asthma. The results of the study confirmed the presence of high-er amount of exhaled nitric oxide in patients with asthma and bronchial hyper-responsiveness. The elevation of NO concen-tration correlated with age; there was no significant difference between sexes.
