Maple syrup urine disease (MSUD), an inborn error of amino acids catabolism is characterized by accumulation of branched chain amino acids (BCAAs) leucine, isoleucine, valine and their corresponding alpha-ketoacids. Impact on the cognitive development has been reported historically, with developmental delays of varying degree. Currently, earlier diagnosis and improved management allow a better neurodevelopment, without requirement of special education. However, specific impairments can be observed, and so far, results of detailed neurocognitive assessments are not available...

INTRODUCTION: The clinical features of UTI in young children may not localize to the urinary tract and closely resemble other febrile illnesses. In malaria endemic areas, a child presenting with fever is often treated presumptively for malaria without investigation for UTI. Delayed or inadequate treatment of UTI increases the risk of bacteremia and renal scarring in young children and subsequently complications as hypertension and end stage renal disease in adulthood. METHODS: A cross-sectional study was carried out in a hospital in western Kenya...

We report a rare case of allograft loss from acute Page kidney secondary to trauma that occurred 12 years after kidney transplantation. A 67-year-old Caucasian male with a past surgical history of kidney transplant presented to the emergency department at a local hospital with left lower abdominal tenderness. He recalled that his cat, which weighs 15 lbs, jumped on his abdomen 7 d prior. On physical examination, a small tender mass was noticed at the incisional site of the kidney transplant. He was producing a normal amount of urine without hematuria...

BACKGROUND AND OBJECTIVES: An estimated 400,000 urinary tract infections (UTIs) are diagnosed annually in children aged <3 years in the United States; yet >50% of febrile UTIs may be missed in this population. Here, we explored possible barriers to diagnosing febrile UTIs in very young children through social research of community pediatricians. METHODS: Following qualitative interviews, a quantitative survey was developed that included a high-risk case for febrile UTI, presented before prompting for the topic of the survey, to gauge practice of delayed testing...

Pathogenic Leptospira sp. are spirochetal bacteria responsible for leptospirosis, an emerging worldwide zoonosis. These spirochetes are very successful pathogens that infect a wide range of hosts such as fish, reptiles, birds, marsupials, and mammals. Transmission occurs when chronically infected animals excrete live bacteria in their urine, contaminating the environment. Leptospira sp. enter their hosts through damaged skin and mucosa. Chronically infected rats and mice are asymptomatic and are considered as important reservoirs of the disease...

PURPOSE: Development of delayed graft function (DGF) following kidney transplant is associated with poor outcomes. An ability to rapidly identify patients with DGF versus those with immediate graft function (IGF) may facilitate the treatment of DGF and the research needed to improve prognosis. The purpose of this study was to use a Targeted Urine Proteome Assay (TUPA) to identify protein biomarkers of delayed recovery from kidney transplant. EXPERIMENTAL DESIGN: Potential biomarkers were identified using the TUPA Multiple Reaction Monitoring (MRM) assay to interrogate the relative DGF/IGF levels of expression of 167 proteins in urine taken 12-18 hours after kidney implantation from 21 DGF, 15 SGF (slow graft function), and 16 IGF patients...

In the United States, rat-bite fever is a rare systemic illness principally caused by Streptobacillus moniliformis, an organism found in the nasopharyngeal flora of rodents. Infection through direct exposure to rat excreta such as saliva, urine, or feces can lead to fever, rash, and an asymmetric migratory polyarthritis. As rodents are becoming more popular as pets, more pediatric cases are being documented. We report a pediatric case of delayed onset septic arthritis in the left wrist and right knee due to S...

AIMS: Urease is a key virulence factor for the Gram-positive urinary tract pathogen Staphylococcus saprophyticus and a potential target for antimicrobial therapy. The enzyme from S. saprophyticus is unusual in that it does not contain cysteine at the active site. The aims of this study were to test fourteen over-the-counter plant preparations as inhibitors of this urease and to determine if they can prevent the increase in pH that normally occurs in bacterial cultures containing urea...

In April 2014, a kidney transplant recipient in the United States experienced headache, diplopia, and confusion, followed by neurologic decline and death. An investigation to evaluate the possibility of donor-derived infection determined that 3 patients had received 4 organs (kidney, liver, heart/kidney) from the same donor. The liver recipient experienced tremor and gait instability; the heart/kidney and contralateral kidney recipients were hospitalized with encephalitis. None experienced gastrointestinal symptoms...

INTRODUCTION: Guanidinoacetate methyltransferase (GAMT) deficiency is an inborn error of metabolism (IEM), clinically characterized by intellectual disability, developmental delay, seizures, and movement disorders. Biochemical diagnosis of GAMT deficiency is based on the measurement of creatine and guanidinoacetate in urine, plasma, or CSF and is confirmed genetically by DNA analysis or by enzyme assay in lymphoblasts or fibroblasts. To obtain enough cells, these cells need to be cultured for at least 1 month...

BACKGROUND: Congenital tuberculosis is a rare manifestation of tuberculosis. The diagnosis is often delayed, especially in preterm neonates because of the non-specific clinical presentation and the lack of awareness of maternal disease prior to pregnancy. CASE PRESENTATION: We report a case of congenital tuberculosis in an infant born at 24 weeks of gestation to a mother who presented with uncontrolled seizures during preterm labor. Maternal diagnosis was initially made by placental pathology, and later confirmed by isolation of Mycobacterium tuberculosis in urine, gastric aspirates and sputum...

Acetylsalicylic acid (Aspirin, ASA) is a famous drug for cardiovascular diseases in recent years. Effects of ASA dosage on the metabolic profile have not been fully understood. The purpose of our study is to establish a rapid and reliable method to quantify ASA metabolites in biological matrices, especially for glucuronide metabolites whose standards are not commercially available. Then we applied this method to evaluate the effects of ASA dosage on the metabolic and excretion profile of ASA metabolites in rat urine...

d-Glyceric aciduria is caused by deficiency in d-glycerate kinase (GK) due to recessive mutations in the GLYCTK gene. GK catalyzes the conversion of d-glycerate to 2-phosphoglycerate which is an intermediary reaction in the catabolism of serine and fructose. Deficiency of GK leads to accumulation of d-glycerate, which may be detected in urine organic acid analysis. Debate exists as to whether this is a benign or disease-causing disorder as the reported phenotypes vary significantly. We report two siblings from a consanguineous Pakistani family...
