Thiosulfate formation and biodegradation processes link aerobic and anaerobic metabolism of cysteine. In these reactions, sulfite formed from thiosulfate is oxidized to sulfate while hydrogen sulfide is transformed into thiosulfate. These processes occurring mostly in mitochondria are described as a canonical hydrogen sulfide oxidation pathway. In this review, we discuss the current state of knowledge on the interactions between hydrogen sulfide and hemoglobin, myoglobin and neuroglobin and postulate that thiosulfate is a metabolically important product of this processes...

Bladder perforation, especially when atraumatic, is a rare cause of ascites and is often difficult to differentiate from other causes of abdominal pain and ascites in the acute setting.  A 43-year-old Caucasian woman with a history of multiple sclerosis presented with acute abdominal pain. A computed tomography (CT) scan of her abdomen and pelvis without contrast revealed ascites, acute kidney injury (AKI) was noted on laboratory workup, and very little urine was drained by Foley catheter. Over the next several days, the patient's clinical condition deteriorated with no definitive diagnosis...

Von Hippel-Lindau disease (vHL) is a hereditary tumor predisposition syndrome that places affected individuals at risk for multiple tumors, which are predominantly benign and generally occur in the central nervous system or abdomen. Although the majority of tumors occur in adults, children and adolescents with the condition develop a significant proportion of vHL manifestations and are vulnerable to delayed tumor detection and their sequelae. Although multiple tumor screening paradigms are currently being utilized for patients with vHL, surveillance should be reassessed as the available relevant clinical information continues to expand...

Maple syrup urine disease is an autosomal metabolic disease caused by a deficiency of branched-chain α-keto acid dehydrogenase complex activity. In this disease occur the accumulation of the branched-chain amino acids leucine, isoleucine, and valine and their corresponding branched-chain α-keto acids in the tissues and body fluids. The affected patients may present psychomotor development delay and mental retardation. The pathophysiology of maple syrup urine disease is not entirely understood, but leucine seems to be the primary neurotoxic metabolite...

A 55-year-old woman, diagnosed with a renal mass by abdominal ultrasonography (USG) in an external medical centre, presented to our hospital. The medical history was unremarkable except for diabetes mellitus and hypertension. The haemogram and urine tests were normal. The only pathology revealed in routine biochemistry tests was increased glucose level (164 mg/dL). The repeat USG performed in our hospital revealed a solid hypoechoic mass lesion approximately 4 cm in diameter closely adjacent to the right kidney...

Sodium-glucose cotransporter 2 (SGLT2) inhibitors are able to provoke diabetic ketoacidosis (DKA) with absence or low levels of ketone bodies in urine and slightly elevated blood glucose levels, which could delay the diagnosis; however, the presence of high urine output, due to the excretion of glucose, can help to identify the true cause.

BACKGROUND: Oblique lumbar interbody fusion surgery is a recently introduced minimally invasive lateral interbody fusion surgery for degenerative lumbar disease. There have been no reports of associated ureteral injury. CASE PRESENTATION: A 77-year-old Japanese woman underwent oblique lumbar interbody fusion surgery for lumbar spondylolisthesis with refractory low back pain and pain in both legs. The patient experienced abdominal pain 2 days after surgery. Delayed contrast-enhanced computed tomography and retrograde urography revealed leakage of contrasted urine from the ureter into the retroperitoneal space, indicating a ureteral injury...

BACKGROUND: Genitourinary tuberculosis is the third most common form of extrapulmonary tuberculosis. Diagnosis is difficult because of unspecific clinical manifestations and low accuracy of conventional tests. Unfortunately, the delayed diagnosis impacts the urinary tract severely. Nucleic acid amplification tests yield fast results, and among these, new technologies can also detect drug resistance. There is lack of consensus regarding the use of these tests in genitourinary tuberculosis; we therefore aimed to assess the accuracy of nucleic acid amplification tests in the diagnosis of genitourinary tuberculosis and to evaluate the heterogeneity between studies...

Renal replacement therapy for acute kidney injury has been used for more than 60 years. Except when life-threatening metabolic complications such as severe hyperkalaemia are present, renal replacement therapy initiation criteria are the subject of intense debate. Significant progress has been made with the publication of the AKIKI multicenter trial, which showed that a delayed renal replacement therapy initiation strategy (in the absence of life-threatening metabolic complications) was not associated with a difference in mortality compared to an early renal replacement therapy initiation strategy...

INTRODUCTION: Urine neutrophil gelatinase-associated lipocalin (uNGAL) is a sensitive and specific diagnostic test for acute kidney injury (AKI) in the Emergency Department (ED), but its economic impact has not been investigated. We hypothesized that uNGAL used in combination with serum creatinine (sCr) would reduce costs in the management of AKI in patients presenting to the ED in comparison to using sCr alone. MATERIALS AND METHODS: A cost simulation model was developed for clinical algorithms to diagnose AKI based on sCr alone vs...

OBJECTIVE: Prospectively monitor how treatment of acutely ruptured anterior cruciate ligament (ACL) affects biomarkers of inflammation and proteolytic degradation over 5 years. DESIGN: We studied 119 subjects with acute ACL injury from the randomized controlled KANON-trial (Clinical trial ISRCTN 84752559) who had synovial fluid, serum and urine samples available from at least two out of six visits over 5 years after acute ACL rupture. All subjects followed a similar rehabilitation protocol where, according to randomization, 60 also had early ACL reconstruction and 59 had the option to undergo a delayed ACL reconstruction if needed...

Pyrethroids, a class of ubiquitous insecticides, have been considered as endocrine-disrupting chemicals (EDCs). Female animal studies suggested that early-life pyrethroids exposure might delay puberty onset. However, it remains unclear whether this association applies to human populations. A total of 305 girls at the ages of 9-15 years old were recruited in Hangzhou, China in this study. The concentration of the common metabolite of pyrethroids, 3-phenoxybenzoic acid (3-PBA), was analyzed in urine samples to reflect the exposure level of pyrethroids...

We present an unusual case of shunt nephritis in a 39-year-old male who presented 21 years after placement of a ventriculoperitoneal (VP) shunt. He complained of fevers, headaches, dizziness, and urticarial plaques on arms, trunks, and legs and was found to have anemia, low complement levels, elevated serum creatinine, proteinuria, and new onset microhematuria. Blood and urine cultures were negative. Renal biopsy showed features of acute tubulointerstitial nephritis attributed to vancomycin use. Glomeruli showed increased mesangial hypercellularity and segmental endocapillary proliferation...

We report the utility of surface-enhanced Raman scattering (SERS) analysis of urine from deceased donors for prognosis of kidney transplant outcomes. Iodide-modified silver nanoparticles were used as the enabler for sensitive measurements of urine proteins. Principal component analysis (PCA) and linear discriminant analysis (LDA) were employed for the statistical analysis of the SERS data. Thirty urine samples in three classes were analysed. The ATN class consists of donors whose kidneys had acute tubular necrosis (ATN), the most common type of acute kidney injury (AKI) with high risk of poor graft performance in recipients, yet yielded acceptable transplant outcome...
