Neoadjuvant nivolumab and cabozantinib in advanced renal cell carcinoma in a horseshoe kidney - how to achieve a safe and radical resection? a case report and review of the literature.

Introduction: Neoadjuvant nivolumab and cabozantinib in locally advanced renal cell carcinoma in a horseshoe kidney is a novel therapeutic approach in the preoperative setting.

Methods: We report a case of a 52-year old male who presented with a large inoperable tumor of the horseshoe kidney and achieved major partial radiologic response after neoadjuvant therapy with nivolumab and cabozantinib leading to radical resection of the tumor. The patient remains tumor free on the subsequent follow-up and his renal function is only mildly decreased.

A founder pathogenic variant resulting in autosomal recessive Alport syndrome accounts for most genetic kidney failure in Romani people.

Introduction: Romani people have a high prevalence of kidney failure. This study examined a Romani cohort for pathogenic variants in the , and genes that are affected in Alport syndrome (AS), a common cause of genetic kidney disease, characterized by hematuria, proteinuria, end-stage kidney failure, hearing loss, and eye anomalies.

Materials And Methods: The study included 57 Romani from different families with clinical features that suggested AS who underwent next-generation sequencing (NGS) of the genes, and 83 family members.

Extracorporeal shockwave lithotripsy in combination with endoscopy as a treatment modality for painful chronic obstructive pancreatitis – a case report.

Chronic pancreatitis (CP) is a serious condition with a great impact on the quality of life, and it can lead to some serious long-term consequences such as pancreatic cancer or secondary diabetes mellitus. Associated pancreatic exocrine insufficiency leads to malnutrition with weight loss; however, the main symptom of the disease is abdominal pain, often very severe. The primary treatment option for painful CP is pharmacotherapy (pancreatic enzyme replacement therapy, analgesics).

TUBULOINTERSTITIAL NEPHRITIS WITH UVEITIS (TINU SYNDROME). A CASE REPORT.

In this case report, we describe the case of a 50-year-old woman referred by her general practitioner to a pulmonologist in order to investigate persistent fever and elevation of C-reactive protein despite antibiotic treatment following a respiratory infection. The patient was examined extensively, during which rheumatology, gastroenterology, nephrology, ophthalmology, laboratory and imaging tests were performed. Due to a rapid progression of renal insufficiency with active urinary sediment, the patient was referred for a renal biopsy, which confirmed tubulointerstitial nephritis, followed by a diagnosis of bilateral anterior uveitis two months later - genetic testing was also conducted, which confirmed the diagnosis of tubulointerstitial nephritis with uveitis syndrome.

Antineutrophil Cytoplasmic Autoantibody-Associated Glomerulonephritis as a Complication of Home Parenteral Nutrition.

Patients on long-term home parenteral nutrition (HPN) occasionally develop glomerulonephritis due to chronic central venous catheter (CVC)-related infection. Most previously reported cases were membranoproliferative glomerulonephritis (MPGN). This is a case report of a 16-year-old girl receiving HPN for short bowel syndrome.

Current Status, Prevention and Treatment of BK Virus Nephropathy.

All renal transplant recipients should undergo a regular screening for BK viral (BKV) viremia. Gradual reduction of immunosuppression is recommended in patients with persistent plasma BKV viremia for 3 weeks after the first detection, reflecting the presence of probable or suspected BKV-associated nephropathy. Reduction of immunosuppression is also a primary intervention in biopsy proven nephropathy associated with BKV (BKVN).

Mathematical Modelling of Temperature Distribution in Selected Parts of FFF Printer during 3D Printing Process.

This work presented an FEM (finite element method) mathematical model that describes the temperature distribution in different parts of a 3D printer based on additive manufacturing process using filament extrusion during its operation. Variation in properties also originate from inconsistent choices of process parameters employed by individual manufacturers. Therefore, a mathematical model that calculates temperature changes in the filament (and the resulting print) during an FFF (fused filament fabrication) process was deemed useful, as it can estimate otherwise immeasurable properties (such as the internal temperature of the filament during the printing).

Nephrotoxicity of calcineurin inhibitors as a risk factor for BK polyomavirus replication after kidney transplantation.

BK polyomavirus-associated nephropathy (PyVAN) is responsible for a significant percentage of transplanted kidneys prematurely terminating their function. Its occurrence is closely related to the intensity of immunosuppressive therapy. In a group of 161 newly transplanted patients, we prospectively evaluated 457 protocol renal biopsies performed within the first year after transplantation.

Description of the twelfth species of the genus Thermistis Pascoe, 1867 (Coleoptera: Cerambycidae: Lamiinae: Saperdini).

Thermistis Pascoe, 1867 (Cerambycidae: Lamiinae: Saperdini) is a large and brightly coloured Oriental saperdine genus. It was thoroughly revised by Lin et al. (2012), with 11 species from the Oriental region.

Cochlear Implantation.

Historically, cochlear implants are the first substitute for a sensory modality, hearing. In past decades, they have become a standard method of a compensation for a hearing loss, both for children and adults. Because of restored hearing by cochlear implants, people were able to keep their jobs, marriages and other social ties.

Dabrafenib monotherapy in BRAF+ non-small cell lung cancer - our experience.

Background: Activating BRAF mutations result in constitutive activation of the MAP kinase signaling cascade, stimulating cell proliferation. BRAF mutations are typical for malignant melanoma, but occur less frequently in other tumors, including in 1-2% cases of non-small cell lung cancer (NSCLC) [1,2].

Case: We present two case reports of BRAF+ NSCLC patients, treated with 3rd line dabrafenib monotherapy on our department, and also brief review of available information about dabrafenib and its use in monotherapy of BRAF+ NSCLC.

Enhanced Oral Bioavailability of 2-(Phosphonomethyl)-pentanedioic Acid (2-PMPA) from its (5-Methyl-2-oxo-1,3-dioxol-4-yl)methyl (ODOL)-Based Prodrugs.

2-(Phosphonomethyl)-pentanedioic acid (2-PMPA) is a potent (IC = 300 pM) and selective inhibitor of glutamate carboxypeptidase II (GCPII) with efficacy in multiple neurological and psychiatric disease preclinical models and more recently in models of inflammatory bowel disease (IBD) and cancer. 2-PMPA (), however, has not been clinically developed due to its poor oral bioavailability (<1%) imparted by its four acidic functionalities ( Log  = -1.14).

Sphingosine kinase-1 predicts overall survival outcomes in non-small cell lung cancer patients treated with carboplatin and navelbine.

Sphingosine 1-phosphate (S1P) is a bioactive lipid metabolite associated with cancer cell proliferation, survival, migration and regulation of tumor angiogenesis in various cellular and animal models. Sphingosine kinase-1 (SphK1) and S1P lyase are the main enzymes that respectively control the synthesis and degradation of S1P. The present study analyzed the prognostic and predictive value of SphK1 and S1P lyase expression in patients with non-small cell lung cancer (NSCLC), treated with either surgery alone or in combination with adjuvant carboplatin and navelbine.

Metastatic Clear Cell Renal Carcinoma Without Evidence of a Primary Renal Tumour Mimicking Advanced Stage of Malignant Lung Tumour.

Background: Clear cell renal carcinoma (ccRC) accounts for 65-70% of renal carcinomas with peak occurrence at the 6th and 7th age decade, predominantly in males. At the time of diagnosis, especially pulmonary metastases can be found in one-third of patients. There have also been described as late metastases for several decades after nephrectomy.

Exposure criteria for evaluating lumbar spine load.

Objective: As a part of regular revision of the List of Occupational Diseases in the Czech Republic, efforts have been made to add a new item so that lumbar spine disease caused by overload may be recognized as occupational one, with adherence to the valid national rules, that is, clinical criteria are met and objective assessment confirms working conditions under which, according to recent scientific knowledge, such an occupational disease develops. The aim is to provide information on the use of a proposed method for working condition assessment in a real setting, based on the initial experiences gained from a pilot study carried out to validate the method.

Methods: Working conditions were assessed in 55 individuals with chronic low back pain (25 males, 30 females; mean age 45.

Silicosis, caused by inhaling dust containing free crystalline silica, typically has a chronic course, with the numbers of silicosis patients declining globally. Much rarer are the acute and subacute forms. Presented is a case of severe subacute (accelerated) silicosis.

Real life adjuvant chemotherapy uptake and survival in patients with non-small cell lung cancer after complete resection.

Objectives: Adjuvant chemotherapy (AC) in non-small cell lung cancer (NSCLC) has become a standard of care in patients with stages IIA, IIB, and IIIA after complete tumor resection. Utilization and outcome of AC in routine practice is described in a few studies, with non-conclusive results.

Materials And Methods: This retrospective study included consecutive patients with NSCLC who underwent curative-intent surgery.

BK virus-induced renal allograft nephropathy.

BK virus nephropathy (BKVN) is a serious opportunistic infection threatening renal function especially during the first year after transplantation. Its incidence is now on the rise and is closely related to the level of the recipient's immune system inhibition. This is more intensive with current trends in transplantation medicine, where more potent immunosuppressive protocols are used and more aggressive antirejection therapy is applied.

N-Substituted Prodrugs of Mebendazole Provide Improved Aqueous Solubility and Oral Bioavailability in Mice and Dogs.

Mebendazole (MBZ) was developed as a broad-spectrum anthelmintic but has recently shown efficacy as an anticancer agent. The use of MBZ for cancer, however, is challenging due to its poor solubility leading to poor bioavailability. Herein, we developed a prodrug approach with various N-linked promoieties including acyloxymethyl, aminoacyloxymethyl, and substituted phosphonooxymethyl in attempt to improve these characteristics.
