Purpose: The objective of this study is to analyse the appropriateness of lower extremity coputed tomography (CT) scans as performed in a large orthopaedic hospital. Material and methods: A total of 1410 CT scans acquired in the years 2014-2018 were analysed for compliance with the "Guidelines for Physicians Issuing Diagnostic Imaging Referrals" (iRefer). These guidelines were published by the Royal Radiologist Society and recommended for use by the Polish Medical Society of Radiology, the National Consultant for Radiology and Diagnostic Imaging, and the Minister of Health. In addition, the study involved the analysis of information provided on CT referrals by referring clinicians. Results: Nearly 21% of CT referrals were found to be unsubstantiated based on the diagnosis made by the referring physician, the body region of interest, and the clinical department. Most referrals identified as non-compliant with the guidelines were related to cancers followed by inflammatory conditions. The lowest number of unjustified exams was reported for endoprostheses and injury-related cases. Conclusions: The study revealed a significant degree of non-compliance with the diagnostic algorithm as defined in the iRefer guidelines, particularly in cases of cancers and inflammatory conditions. Consequently, the patient's exposure to ionizing radiation is increased. Incorrect decisions regarding the appropriate diagnostic imaging technique are founded on the lack of appropriate cooperation between the clinician and the radiologist, insufficiency or lack of information provided on the referral, as well as the defensive attitude of referring physicians. It is therefore necessary to change appropriate in-hospital management and cooperation models.

Spinal adhesive arachnoiditis is a rare pathology involving pia mater of the spinal cord and nerve roots. It can potentially lead to disability—many patients end up wheelchair-bound due to subsequent paraparesis. It is an infrequent but possible cause of lower extremities weakness in patients with a history of spinal surgery, epidural anaesthesia, myelography or spinal tumors. Three patients, one male and two females, admitted to our unit due to paraparesis presented at least one of the above mentioned risk factors. Each of them had a severe course of illness—progressive paresis of lower extremities. All above cases were diagnosed with spinal adhesive arachnoiditis confirmed with Magnetic Resonance Imaging (MRI) scan—the most sensitive and specific diagnostic tool. Despite conservative treatment and intensive rehabilitation none of the presented patients preserved the ability to mobilise independently. Considering spinal adhesive arachnoiditis in patients with paraparesis and history of typical risk factors should be included in clinical diagnostic procedure.

Case series Patients: Male, 13-year-old • Male, 33-year-old • Male, 34-year-old • Male, 35-year-old Final Diagnosis: HNF1B nephropathy • HNF1B-MODY type 5 Symptoms: Diabetic ketoacidosis • elevated liver enzymes • hyperglycemia • hyperuricemia • hypomagnesemia • positive family history • renal cysts • renal magnesium wasting • weigh loss Medication:— Clinical Procedure: Genetic analysis • islet autoantibodies Specialty: Endocrinology and Metabolic • Nephrology Objective: Congenital defects/diseases Background: Maturity onset diabetes of the young (MODY) usually presents in patients under the age of 25 years and is an autosomal dominant condition associated with mutations in the hepatocyte nuclear factor 1 alpha gene, glucokinase gene, or hepatocyte nuclear factor 4 alpha gene. This report is of a series of 4 cases from Poland of MODY type 5 associated with mutations in the hepatocyte nuclear factor 1 beta (HNF1B) gene, including a 13-year-old boy and adult men aged 33, 34, and 35 years. Case Reports: Three cases were diagnosed late, in patients in their mid-thirties. In two patients, the initial presentation was symptomatic diabetes complicated by ketoacidosis and hyperglycemic hyperosmolar state. Renal cysts were found in all patients, and pancreatic hypoplasia in 3 patients. All patients except 1 were negative for autoanti-bodies; 1 presented with hypomagnesemia. Insulin therapy was instituted in all cases. The combination of family history, imaging study results, and biochemical characteristics led to the decision to perform genetic analysis, which was conducted in 2 cases at diagnosis, and in the 2 remaining patients at 1 month and 2 years after diagnosis, respectively. Follow-up data revealed hypomagnesemia and/or hypermagnesuria in all patients. Conclusions: We present 3 young men over 25 years and 1 boy with HNF1B-MODY. Although rare, autosomal dominant gene associations should be considered in young patients with diabetes who present with renal/pancreatic anomalies and low serum magnesium. Unusual presentation and the presence of autoantibodies should not eliminate the possibility of a HNF1B defect.

Ból jest elementem zmysłu czucia, stanowiącym równocześnie mechanizm obronny, którego istotną rolą jest ograniczanie skutków urazu. Odczuwanie bólu jest zmienne i zależy od czynników środowiskowych, rasy, pochodzenia etnicznego, materialnego poziomu życia, narażenia na stres. Zmienność odczuwania bólu może być wyjaśniona przez czynniki genetyczne. Badania prowadzone na zwierzętach i populacjach ludzi wykazały, że zmiany odczuwania bólu zależą od budowy struktur chromosomów, w których zawarte są cechy ilościowe i charakterystyka polimorfizmów pojedynczych nukleotydów (SNP). Zmiany struktur receptorów bólu, błon komórkowych neuronów, mediatorów synaptycznych, modulatorów bólu i receptorów opioidowych może przyczyniać się do znaczących różnic w odczuwaniu bólu. Celem pracy jest przedstawienie ostatnich dokonań w dziedzinie genetycznych uwarunkowań odczuwania bólu.

Purpose Identification of the group of patients meeting the criteria of a severe multiple trauma (polytrauma) among those admitted to the regional trauma centre and subjected to whole-body computed tomography (WBCT) due to injuries. Identification the patients for whom WBCT was the optimal choice. Material and methods Retrospective analysis of the data of 303 patients undergoing WBCT in the period 2015-2017 with assessment of the injury severity based on the abbreviated injury scale (AIS) and injury severity score (ISS). Results Among 303 patients undergoing WBCT due to trauma, multiple injuries with ISS > 15 were found in 74 individuals (24.4%). After excluding patients whose limb fractures increased ISS above 15, the group decreased to 63 patients (20.8%). For these patients, the WBCT may be described as the optimal imaging method at an early stage of management. Conclusions Trauma patients are too often qualified for WBCT. Exposure to a high dose of ionising radiation associated with this modality requires critical analysis of the scope of indications and rules of conduct for trauma teams.

Introduction Urologists are commonly facing the dilemma of elevating prostate-specific antigen (PSA) levels despite a series of negative prostate biopsy results. Although fusion biopsies are being used increasingly, they are not available in many centers. We evaluated the prostate cancer detection rate using transperineal magnetic resonance imaging (MRI) template-guided cognitive biopsy. Material and methods Twenty-two patients with a suspicious lesion on MRI were enrolled into this study and underwent a repeated biopsy. All procedures were done under anesthesia and with antibiotic prophylaxis. Brachytherapy template was applied in each case. Results The median age, PSA and prostate volume were 67 years, 9.2 ng/ml, and 65 ml, respectively. The average number of biopsy cores was 24. Nine patients (41%) were diagnosed with prostate cancer. The grade distribution was Gleason score 7 for 5 patients, and Gleason score 6 for 4 patients. No major complications occurred. Conclusions Transperineal MRI template-guided cognitive prostate biopsy appears to be a safe procedure, which helps to detect significant cancer. The biopsy-associated adverse events are negligible.
