Syngnathidae (seahorses, seadragons and pipefish) suffer significant losses from non-tuberculous mycobacteria. However, they produce markedly different lesions in response to the disease compared to other teleost species, notably infrequent granuloma formation. This study evaluated 270 syngnathid fish, from which 92 were diagnosed with mycobacteriosis by histopathology, culture or both. Microscopic lesions variably consisted of random foci of coagulative necrosis in multiple organs, containing high numbers of free bacteria and large aggregates or sheets of macrophages with cytoplasm laden with acid-fast bacilli...

Horseshoe kidney is the most common renal fusion anomaly found in about 0.15% to 0.25% of the population. Renal cell carcinoma associated with a horseshoe kidney has been described in fewer than 200 cases. Its incidence and prognosis seems to be not different from those of the general population, but surgical management may be challenging due to unique anatomic features of horseshoe kidneys, such as highly variable vasculature. We report a case of a 69-year-old male with an incidental 48-mm solid mass in the left moiety of a horseshoe kidney, successfully treated by retroperitoneoscopic partial nephrectomy...

Proteomic and genomic techniques have reached full maturity and are providing unforeseen details for the comprehensive understanding of disease pathologies at a fraction of previous costs. However, for kidney diseases, many gaps in such information remain to inhibit major advances in the prevention, treatment and diagnostics of these devastating diseases, which have enormous global impact. The discovery of ubiquitous extracellular vesicles (EV) in all bodily fluids is rapidly increasing the fundamental knowledge of disease mechanisms and the ways in which cells communicate with distant locations in processes of cancer spread, immunological regulation, barrier functions and general modulation of cellular activity...

Twenty years ago, we described a kindred of 105 individuals with isolated GH deficiency (IGHD) in Itabaianinha County, in Brazilian northeast, due to a homozygous mutation in the GH-releasing hormone receptor gene. These subjects exhibit markedly reduced GH responsiveness to stimulatory tests, and anterior pituitary hypoplasia. Serum concentrations of IGF-I, IGF binding protein type 3, and the acid-labile subunit are markedly reduced, with a lesser reduction of IGF-II. The most striking physical findings of these IGHD individuals are the proportionate short stature, doll facies, high-pitched voice, and visceral obesity with reduced fat free mass...

BACKGROUND: Chromomycosis is a rare mycotic infection encountered in tropical and subtropical regions. The disease presents as a slowly-evolving nodule that can become infected with bacteria. Here, we describe a unique association of abscesses caused by a chromomycosis and Listeria monocytogenes in a kidney transplant recipient, and didactically expose how the appropriate diagnosis was reached. CASE PRESENTATION: A 49-year old male originating from the Caribbean presented a scalp lesion which was surgically removed in his hometown where it was misdiagnosed as a sporotrichosis on histology, 3 years after he received a kidney transplant...

Cardiac surgery associated-acute kidney injury (CS-AKI) occurs in 30-50% of patients undergoing surgery for congenital heart disease. Here we determine if CS-AKI is associated with chronic kidney disease (CKD) in patients with congenital heart disease. Using Danish regional population-based registries, our cohort study included patients with congenital heart disease born between 1990-2010 with first cardiac surgery between 2005 and 2010 (under 15 years of age). Utilizing in- and out-patient laboratory serum creatinine data, we identified individuals fulfilling KDIGO stages of AKI within 5 days of cardiac surgery...

The management of patients with hereditary kidney cancers presents unique challenges to clinicians. In addition to an earlier age of onset compared with patients with sporadic kidney cancer, those with hereditary kidney cancer syndromes often present with bilateral and/or multifocal renal tumors and are at risk for multiple de novo lesions. This population of patients may also present with extrarenal manifestations, which adds an additional layer of complexity. Physicians who manage these patients should be familiar with the underlying clinical characteristics of each hereditary kidney cancer syndrome and the suggested surgical approaches and recommendations of genetic testing for at-risk individuals...

Two-photon intravital microscopy is a powerful tool that allows the examination of dynamic cellular processes in the live animal with unprecedented resolution. Indeed, it offers the ability to address unique biological questions that may not be solved by other means. While two-photon intravital microscopy has been successfully applied to study many organs, the kidney presents its own unique challenges that need to be overcome in order to optimize and validate imaging data. For kidney imaging, the complexity of renal architecture and salient autofluorescence merit special considerations as these elements directly impact image acquisition and data interpretation...

REVIEW
Rebecca J Schmidt
Patients with chronic kidney disease typically suffer a cascade of comorbid conditions, the magnitude of which have formidable impact on advance care planning (ACP). Complex health care decisions are complicated further by contextual issues that may change over time. A dynamic and evolving process, ACP ideally begins early in the continuum of chronic kidney disease, long before end-stage kidney disease is reached. Planning ahead for care is preparatory to making decisions about kidney replacement therapy and can make for a smooth transition in addition to preventing the start of dialysis by default...

The Xenopus genus includes several members of aquatic frogs native to Africa but is perhaps best known for the species Xenopus laevis and Xenopus tropicalis. These species were popularized as model organisms from as early as the 1800s and have been instrumental in expanding several biological fields including cell biology, environmental toxicology, regenerative biology, and developmental biology. In fact, much of what we know about the formation and maturation of the vertebrate renal system has been acquired by examining the intricate genetic and morphological patterns that epitomize nephrogenesis in Xenopus...

BACKGROUND: Emergency departments (EDs) are gateways for patients presenting after minor surgical procedures, particularly shockwave lithotripsy. Complications include renal and extrarenal tissue injuries, with the latter having potentially serious consequences if not detected early. CASE REPORT: We describe a 70-year-old male presenting to the ED for syncope. The patient underwent shockwave lithotripsy (SWL) for left kidney stones 1 day prior. Upon initial evaluation, the patient had normal vital signs and a normal physical examination, without complaints of abdominal pain...

Henoch-Schönlein purpura (HSP) is typically seen as a self-limiting disease in children, but can present more severely in adults, especially when there is renal involvement. Management of HSP in adults also remains a controversial topic with very few studies evaluating available therapies. In this case, HSP presenting as a combination of severe gastrointestinal involvement and a rapid decline in renal function in an adult patient directed our therapy. The patient was a 48-year-old Caucasian male with no known past medical history, who presented with a combination of purpuric rash over the lower extremities, severe abdominal pain with upper gastrointestinal bleeding and a rapidly increasing serum creatinine, with hematuria...

Xenopus is a versatile model organism increasingly used to study organogenesis and genetic diseases. The rapid embryonic development, targeted injections, loss- and gain-of-function experiments and an increasing supply of tools for functional in vivo analysis are unique advantages of the Xenopus system. Here, we review the vast array of methods available that have facilitated its transition into a translational model. We will focus primarily on how these methods have been employed in the study of kidney development, renal function and kidney disease...

PURPOSE OF REVIEW: In comparison with patients who have other serious illnesses, patients with advanced kidney disease have a higher rate of intensive care utilization at the end of life and receive palliative care less frequently. Consensus and clinical practice guidelines have therefore recommended the incorporation of palliative care earlier in the disease trajectory. This review summarizes recent literature on this aspect of care and will highlight future directions for patient-centered care within palliative nephrology...

Hyperlipidemia is a risk factor for initiation and progression of diabetic nephropathy but the metabolic pathways altered in the diabetic kidney in a context of hyperlipidemia remain incompletely described. Assuming that changes in urine composition reflect the alteration of renal metabolism and function, we analyzed the urine metabolite composition of diabetic (streptozotocin-treatment) and control (non diabetic) ApoE-/- mice fed a high cholesterol diet using targeted quantitative metabolomics. Urine metabolome was also compared to the plasma metabolome of the same animals...

In patients with type 2 diabetes mellitus (T2DM), the main cause of morbidity and mortality is cardiovascular (CV) disease. Diabetic kidney disease, which develops in approximately 40% of patients with T2DM, further increases the risk of CV-related morbidity and mortality. The sodium glucose co-transporter 2 (SGLT2) inhibitor empagliflozin, which provides effective glycaemic control as either monotherapy or as an add-on to other glucose-lowering agents in patients with T2DM, was also shown to improve CV and renal outcomes in the large, randomised, placebo-controlled EMPA-REG OUTCOME trial in patients with T2DM at high risk of CV events...

BACKGROUND: The development of acute kidney disease (AKD) following total joint arthroplasty has not been well characterized in the literature. We sought to calculate the incidence and identify risk factors associated with postoperative AKD for patients undergoing total hip arthroplasty (THA) and total knee arthroplasty (TKA). METHODS: A total of 1000 consecutive cases (860 unique patients, including revisions) of TKA or THA performed between January 2010 and May 2016 were identified...
