Prostate cancer is the second most common malignancy in men in Poland. Prostate biopsy remains the gold standard for diagnosis. Every year, the number of procedures is increasing, so knowledge of possible complications is becoming crucial. Over time, a continuous increase in infectious complications of prostate biopsy is observed, so it is important to identify risk factors and preventive methods. Antibiotic prophylaxis is mandatory for prostate biopsy. Simultaneously, complications after prostate biopsy affect as many as 90% of patients, including up to 17% of infective complications...

Kidney cystic diseases are inherited disorders causing chronic renal failure. According to the genetic defect they are classified as diseases of the primary ciliary complex and uromodulin-associated diseases. Mutations in genes coding for ciliary proteins are the basis of a broad category of genetic diseases, called ciliopathies. To date, three important ciliopathies are known: the autosomal dominant form and the recessive shape of the polycystic kidney and the nephronophthisis (NPHP). Juvenile Nephronophthisis (NPHP) is a progressive renal tubulo-interstitial disorder with a form of autosomal recessive inheritance that progresses inexorably towards terminal renal failure...

We describe the case of a 74-year-old man admitted to our Nephrology Unit with nephrotic syndrome and mild kidney disease. A complete panel of laboratoristic and instrumental tests did not provide useful information for diagnosis. No specific signs or symptoms suggested the presence of AL amyloidosis. As a matter of fact, diagnosis was reached thanks to the hystopathologic examination of renal tissue and bone marrow, since the associated B-cell lymphoproliferative disorder had not revealed itself through serum and urine electrophoresis and immunofixation...

We investigated if time between injury and surgery affects cancellous bone properties in patients suffering tibial plateau fractures (TPF), in terms of structural integrity and gene expression controlling bone loss. A cohort of 29 TPF, operated 1-17 days post-injury, had biopsies from the fracture and an equivalent contralateral limb site, at surgery. Samples were assessed using micro-computed tomography and real-time RT-PCR analysis for the expression of genes known to be involved in bone remodeling and fracture healing...

BACKGROUND: Sentinel node navigation surgery (SNNS) in early gastric cancer (EGC) is technically feasible according to previous literature, however its long-term oncologic safety has not been reported. METHODS: A single-center, single-arm, phase II trial was conducted to determine the oncologic outcomes of laparoscopic sentinel node (SN) biopsy in clinical stage T1N0M0 gastric cancer patients. Cases with positive SNs on intraoperative pathologic examination underwent conventional gastrectomy with radical lymphadenectomy (SN-positive group), whereas those with negative SNs underwent laparoendoscopic-limited gastric resections without further lymph node dissections (SN-negative group)...

Background: Lupus nephritis (LN) is classified by renal biopsy into proliferative and nonproliferative forms, with distinct prognoses, but renal biopsy is not available for every LN patient. The present study aimed to establish an alternate tool by building a predictive model to evaluate the probability of proliferative LN. Methods: In this retrospective cohort with biopsy-proven LN, 382 patients in development cohort, 193 in internal validation cohort, and 164 newly diagnosed patients in external validation cohort were selected...

EUS is most commonly used to evaluate and sample lesions of the abdomen but has only been used on rare occasions to evaluate and sample lung lesions. Prior reported cases of EUS sampling of lung lesions were performed by fine-needle aspiration. We present what is believed to be the first reported cases of EUS-guided core biopsy of intraparenchymal lung lesions through two separate case reports. Both patients had the upper lobe lesions not amenable to bronchoscopy or endobronchial ultrasound, and both patients underwent core biopsy without adverse event...

Fine-needle aspiration biopsy (FNAB) of intraocular mass lesions is an important intervention in the presence of diagnostic difficulty. FNAB of intraocular mass lesions is also likely to become more commonly recommended for prognostication of tumors such as choroidal melanoma. The most commonly described approach for tumor localization and visualization during FNAB is transillumination and indirect ophthalmoscopic viewing. Herein, we report endoillumination (chandelier) and wide-angle viewing assisted, microscope-based approach for FNAB in two patients using two port minimally invasive vitreoretinal surgical approach...

BACKGROUND: Previous studies indicate that tight junctions are involved in the pathogenesis of canine atopic dermatitis (cAD). An in vitro skin model is needed to elucidate the specific role of tight junctions in cAD. A 3D epidermal equivalent model using canine progenitor epidermal keratinocytes (CPEK) has been established; the expression of tight junctions within this model is uncharacterized. HYPOTHESIS/OBJECTIVES: To investigate the expression of tight junctions in the 3D epidermal equivalent...
