Algorytm postępowania diagnostyczno-leczniczego w zespołach bólowych kręgosłupa
Back pain is a symptom presented in a broad range of disorders. Blurred or non-specyfic clinical presentation, excessive information from laboratory tests and image techniques, numerous therapeutic options of poor efficiacy evidence, explain difficulties in diagnosing and management of a person with low back pain. According to autor’s clinical observation there is a large number of back pain patients referred to specialized treatment with unrecognized cause and character of main and accompanying disorders. The paper presents an original pattern of diagnostic and therapeutic proceeding with patient apearing with back pain. Important and often neglected aspects of adequate diagnostic and therapeutic proceeding are discussed. The pattern is based on author’s clinical experience and literature review. The algorithm defines a logical consequence of proceeding and validates base for drawing clinical conclusions for an adequate therapeutic program design. Author believes that clinical proceeding according to the presented pattern could facilitate determination of a proper diagnosis and diminish the risk of incorrect treatment consequences.Zespoły bólowe kręgosłupa są wbrew pozorom trudne w diagnozowaniu i leczeniu. Decydują o tym niespecyficzne objawy kliniczne
i czasami bardzo bogate w treści badania dodatkowe. Okazuje się też, że czasami zbyt mało mamy informacji dotyczących rzeczywistego
działania leczniczego niektórych zabiegów stosowanych w fizykoterapii, stąd pojawia się problem oceny skuteczności prowadzonego
leczenia. W pracy przedstawiono propozycję algorytmu diagnostyczno-leczniczego w zespołach bólowych kręgosłupa. Omówiono
najistotniejsze zagadnienia związane z diagnostyką i leczeniem bólów kręgosłupa. W algorytmie zwraca się uwagę na kolejność postępowania
w zależności od uzyskanych informacji dotyczących diagnostyki, a także wskazano na najczęściej stosowane zabiegi terapeutyczne.
Algorytm ma ułatwić postawienie rozpoznania choroby i ograniczyć do minimum błędy wynikające z niewłaściwej diagnozy,
a co za tym idzie niewłaściwego leczenia. Obserwacje kliniczne dowodzą, że zbyt często rozpoznanie zespołów bólowych kręgosłupa
traktuje się ogólnikowo, nie wnikając w szczegóły dotyczące określenia chorej struktury wywołującej objawy chorobowe
Zmiany parametrów wentylacyjnych w trakcie pionizacji osób po urazie rdzenia kręgowego w odcinku szyjnym
Background: Cervical spinal cord injury (CSCI) is followed by mixed respiratory dysfunction.Purpose: Evaluation of the ventilatory parameters of CSCI patients in postures typical for positional training. Material: 51 CSCI patients in a mean age of 34.4 (SD=14.6) years; complete motor deficite (CMD) 66.6%; injury of C5 level or above – 68.6%. Control group(CG): 10 healthy volunteers. Method: Spirometry and flow-volume examination in recumbent (R), sitting (S) and vetrical 60o tilt (V) positions. Main results: Expiratory reserve volume (ERV) undergoes significant positional changes in CG (R: 1.34 L, H: 0.25 L, V: 0.79 L; p=0.02), but not in CSCI patients. Transition from R to S in CMD persons results in a significant decrease in vital capacity (VC) (from 2.45 to 1.75 L; p=0.0008); inspiratory capacity (IC) (from 2.48 to 1.41 L; p=0.0008); forced expiratory volume in 1 second (FEV1) (from 2.21 to 1.64 L; p=0.002); forced vital capacity (FVC) (from 2.55 to 1.78 L; p=0.0004). The FEV1/FVC rate does not depend on positional changes ranging from 89.7% to 93.9% of the reference values. Ventilatory parameters in the incomplete motor deficite (ICMD) group do not differ significantly between the examined body positions. Transition between R and S in the CMD group results in a significant decrease in the peak expiratory flow (PEF) (from 4.23 to 3.53 L/s) and the peak inspiratory flow (PIF) (from 3.89 to 3.43 L/s), while in ICMD the PEF increases from 4.01 to 4.39 L/s and the PIF increases from 3.66 to 4.18 L/s.Conclusions: Transition from R to S in CSCI patients results in increased restriction. CMD patients express a reduction of peak flows while in the ICMD peak flows increase after transition between R and S. Shifting from S to a 60o vertical tilt with standard trunk stabilization does not change significantly the ventilatory parameters in CSCI patients
Współczesne metody oceny układu wydalniczego u osób po urazie kręgosłupa powikłanym zaburzeniami neurologicznymi – diagnostyka dolnych dróg moczowych
Introduction: Spinal injury with neurological deficit usually results in a neurogenic bladder disorder. The problem may range from total lack of micturition during the spinal shock phase to various forms of detrusor-sphincter dyssynergia. Typical consequences include increased intra-vesical pressure, inability to effectively empty the bladder, increased risk of vesico-ureteral reflux, infection, bladder or kidney stones, neoplastic complications within the urinary tract and renal failure. Proper diagnostics of urinary tract function and morphology enables choosing adequate bladder emptying strategy, early diagnosis and effective treatment of urinary complications in patients after spinal injury with neurological deficit.Study purpose: Presentation of contemporary methods of functional, imaging and endoscopic diagnostic tests of the lower urinary tract in patients with spinal injury with neurological deficit. We discuss clinical value and accuracy of particular diagnostic methods in prevention and monitoring of the therapy of urinary complications.Study form: Literature review.Conclusions: Although urodynamic studies serve as the principal tool among the modern methods of the lower urinary tract function assessment, simple functional tests such as measurement of residual urine volume measurement or cystometrogram may be helpful in clinical practice, particularly during the early post-traumatic phase. Ultrasonographic examination is the first choice imaging study. Clinical validity of screening cystoscopy in spinal injury with neurological deficit patients remains doubtful, but this procedure is of unquestionable value in cases with haematuria
Research of Accuracy of the Aircraft Position Using the GPS and EGNOS Systems in Air Transport
The article presents and describes results of research in determination of the aircraft positioning accuracy with use of the GPS and EGNOS satellite systems in the air navigation. The article, in particular, makes a comparison of the designated aircraft coordinates in the GPS and EGNOS systems in relation to the reference position, determined from the precision differential RTK-OTF technique. The experimental test was conducted in Slovakia, in the vicinity of Kosice airport. In the test, a trial flight by Cessna aircraft was executed over the village of Bidovce (LZBD) in Slovakia, in East-Central Europe. Within the conducted investigations, the GPS and EGNOS positioning accuracies were determined in real time during an in-flight experimental test. Based on the conducted investigations, it was found that the accuracy of the GPS positioning in the air navigation equals ±10 m throughout the most part of the air test. In the same period the EGNOS positioning accuracy in air navigation is equal to ± 5 m
Reliability test of a GNSS onboard receiver in the kinematic mode
The article presents the results of the aircraft Cessna 172 positioning based on navigation solutions in the GPS and EGNOS (SBAS) tracking mode. The article makes a comparison of coordinate readings of the Cessna 172 in the ellipsoidal BLh frame. The verification of the coordinates of the aircraft Cessna 172 was used to assess the reliability of the GNSS satellite technique in aviation. In a research test, the navigation data were recorded by the onboard receiver Thales Mobile Mapper during an air test performed over the military aerodrome EPDE in Dęblin. Judging by the conducted investigations, it is possible to conclude that the difference in BLh coordinates of the aircraft Cessna 172 on the basis of the GPS solution and EGNOS (SBAS) solution equals, respectively: from -0.5 m to +3 m for component B; and from -2 m to +6 m for component L; from approximately -11 m to over +1 m for component h. In addition, the paper defines factors of dilution of precision PDOP, based on the GPS and EGNOS (SBAS) solutions. The average value of the PDOP coefficient for a solution in the tracking GPS mode was 2.7, whereas in the EGNOS (SBAS) tracking mode, it was equal to 2.8
The application of the BSSD Iono-Free linear combination method in the processing of aircraft positioning
The article presents the results of research into the use of the differentiation technique of BSSD (Between Satellite
Single Difference) observations for the Iono-Free LC combination (Linear Combination) in the GPS system for the
needs of aircraft positioning. Within the conducted investigations, a positioning algorithm for the BSSD Iono-Free LC
positioning method was presented. In addition, an experimental test was conducted, in which raw observational data
and GPS navigation data were exploited in order to recover the aircraft position. The examination was conducted for
the Cessna 172 and the on-board dual-frequency receiver Topcon HiperPro. The experimental test presents the results
of average errors of determining the position of the Cessna 172 in the XYZ geocentric frame and in the ellipsoidal BLh
frame. Furthermore, the article presents the results of DOP (Dilution of Precision) coefficients, the test of the Chi
square internal reliability test and the HPL and VPL confidence levels in GNSS precision approach (PA) in air
transport. The calculations were performed in the original APS software (APS Aircraft Positioning Software)
developed in the Department of Air Navigation of the Faculty of Aeronautics at the Polish Air Force University
Wpływ urazu kręgosłupa powikłanego zaburzeniami neurologicznymi na funkcje seksualne – dysfunkcje seksualne u mężczyzn
Sexual impairment and decreased fertility constitute a part of a complex dysfunction typical for men with spinal injury with neurological consequences (SINC). Despite the progress in medical sciences and quality of care provided for disabled persons, the problem is often neglected by medical professionals and caregivers.Aim of the study: Presentation of patophysiological background and specificity of sexual dysfunction typical for men following SINC. Review of contemporary treatment modalities designed for erectile dysfunction and infertility in men after SINC.Method: Literature review, authors’ clinical experience.Results and conclusions: Specific neurological deficit with overlapping adaptation problems and depression account for erectile dysfunction in men after SINC. There is a wide range of efficient therapies addressed to patients suffering from erectile disturbances resulting from SINC. Selection of a proper therapy depends on location (level) of the lesion of a neural structure, type of deficit, functional status, presence of symptoms of autonomic dysreflexia, concomitant diseases and patient’s individual preferences. Patient’s awareness of the disability and positive attitude towards acceptance of alternative forms of sexual expressions are crucial for the therapeutic success. Ejaculation dysfunction and infertility are common among men after SINC. Application of contemporary methods of assisted reproduction may be efficient in about half of male population with SINC
Impact of spinal injury with neurological consequences on sexual function: Sexual dysfunctions in women

Współczesne metody oceny układu wydalniczego u osób po urazie kręgosłupa powikłanym zaburzeniami neurologicznymi – diagnostyka górnych dróg moczowych
Introduction: Morbidity and mortality related to urinary tract diseases in patients after spinal injury with neurological disturbances (SIND) are modifiable if prompt and rational diagnostics and therapy are implemented in comprehensive care. SIND increases the risk of urinary tract damage resulting from neurogenic bladder dysfunction, sequels of patient’s immobilisation, nephrotoxic effect of pharmacotherapy, necessity of bladder catheterisation. Severe damage to the urinary system resulting from reflux, urolithiasis, hydronephrosis, recurrent pyelonephritis can occur both during the early and the late phase following SIND. The risk of urinary tract cancer is markedly increased in SIND patients. The natural history of urinary tract diseases in SIND patients might be changed. The course of the disease can be scant in symptoms and signs until late stages. Study design: Overview of scholarly literature.Aim of the study: Presentation and analysis of clinical usefulness of modern tests applied in diagnostics of the urinary tract function in SIND patients. We discussed appropriateness and clinical usefulness of imaging and functional procedures of the upper urinary tract evaluation with special emphasis on basic laboratory tests, modern methods of glomerular filtration rate (GFR) assessment in SIND patients, as well as on the traditional and modern imaging studies.Conclusions: Modern comprehensive care of a patient with SIND, both at the early and late stage following spinal injury, should comprise systematic monitoring of renal function. Efficacious diagnosis is based on meticulous clinical examination. Auxiliary tests are performed according to their availability and the anticipated clinical relevance. First line diagnostic tests should comprise non-invasive techniques. Systematic and credible GFR assessment is indicated in SIND patients. Tests of choice include: 51CrEDTA or 99mTcDTPA clearance, assessment of cystatin-C level, as well as routine imaging studies of the kidneys such as renal radioisotope scanning and ultrasound examination. Urography and computed tomography may serve as auxiliary imaging techniques
The Positioning of the Aircraft Using GPS/GLONASS Data
The article presents the results of aircraft positioning using GPS/GLONASS data in air navigation. In the work, the flight trajectory of the Cessna 172 aircraft was determined on the basis of GPS, GLONASS and GPS/GLONASS data. The coordinates of the Cessna 172 were determined using the least squares method in a stochastic processing compliant with the ICAO recommendations. In the air test, the Cessna 172 made a test flight over EPDE military airfield in Dęblin. The GPS, GLONASS and GPS/GLONASS measurement data from the Topcon HiperPro on-board aircraft installed on the Cessna 172 aircraft were used in the research experiment. The coordinates of the Cessna 172 in the geocentric XYZ and ellipsoidal BLh were compared with the precise flight reference trajectory determined from the differential technique RTK-OTF
