Primary hyperparathyroidism is one of the most common endocrine diseases, however, it is rare in children. In most cases, it is caused by adenoma of these organs. Its most common complications include urolithiasis, nephrocalcinosis and osteoporosis. CASE REPORT: A 16-year-old patient was admitted to our Clinic because of his first-ever renal colic. The ultrasound examination revealed rightsided hydronephrosis caused by the presence of 9 mm stone in the upper part of the right ureter. In addition, the presence of 8 mm stone in the middle calyx of the left kidney was found...

Nephrolithiasis, urolithiasis, and nephrocalcinosis (NC) have become common causes of hospitalization and referral to pediatric outpatient clinics. It is of utmost importance to start with diagnostic evaluation directly after the first passage of a kidney stone, or if NC is diagnosed, in each pediatric patient. This is necessary, as in about 80% of children a metabolic reason for stone disease is detected. Current treatment options are scarce and mainly include general measures like an increased fluid intake or elevating the solubility of a lithogenic substance...

OBJECTIVES: The involvement of the gut microbiota in the pathogenesis of calcium nephrolithiasis has been hypothesised since the discovery of the oxalate-degrading activity of Oxalobacter formigenes , but never comprehensively studied with metagenomics. The aim of this case-control study was to compare the faecal microbiota composition and functionality between recurrent idiopathic calcium stone formers (SFs) and controls. DESIGN: Faecal samples were collected from 52 SFs and 48 controls (mean age 48±11)...

Nephrolithiasis is a rare disease in children. For many years children with kidney stones have been managed like "small adults", but there are significant differences between the pediatric and the adult age in clinical presentation, etiology and treatment. Management of this condition in children has some peculiarities with respect to the adult, as it is often the sign of an underlying metabolic abnormality. Some of these metabolic alterations can lead to serious consequences, such as chronic renal failure, if not adequately diagnosed and treated...

Kidney stones is increasingly associated with obesity. With an increasing prevalence of obesity and metabolic syndrome in the past 30 years, urinary oxalate has significantly increased. However, its underlying pathophysiologic mechanisms of hyperoxaluria have not been fully explored. This preclinical study suggests that hyperoxaluria in obesity depends on a complex network of inflammatory responses linked to metabolic outcome. The future mechanistic and clinical investigations must be targeted at elucidating the pathogenetic role of inflammation in obesity induced hyperoxaluria...

Importance: Because of the aging population, osteoporotic fractures are an increasingly important cause of morbidity and mortality in the United States. Approximately 2 million osteoporotic fractures occurred in the United States in 2005, and annual incidence is projected to increase to more than 3 million fractures by 2025. Within 1 year of experiencing a hip fracture, many patients are unable to walk independently, more than half require assistance with activities of daily living, and 20% to 30% of patients will die...

Seven subunits of the mitochondrial contact site and cristae junction (CJ) organizing system (MICOS) in humans have been recently described in function and structure. QIL1 (also named MIC13) is a small complex that is crucial for the maintenance and assembling of MICOS. A novel mutation of an essential splice site in the C19orf70 gene encoding QIL1 induces severe mitochondrial encephalopathy, hepatopathy and lactate acidosis consistent with psychomotor retardation. In addition, bilateral kidney stones were observed...

BACKGROUND: Evidence has indicated that immediate family members of nephrolithiasis patients had high opportunity to develop stones. However, they are usually not regarded to be at risk, since it is unclear if there are any lithogenic abnormalities found in non-stone-forming nephrolithiasis relatives. Our aim was to investigate urinary metabolic abnormalities in the children of nephrolithiasis patients, compared with the general population. METHODS: The 24-h urinary metabolic profile was studied for 28 calcium oxalate nephrolithiasis patients (NL) and 46 of their descendants (ND), as well as 40 non-stone-forming volunteers (V) and 34 of their descendants (VD)...

Boron plays roles in the metabolism of calcium, vitamin D, steroid hormones, healthy bone development, and maintenance of cell membranes. The biological effects of boron are dose-dependent but follow a U-shaped pattern, rendering it important to define the active range. The studies of Bahadoran et al. on rats and Naghii et al. on humans showed that low doses of boron (3 and 10 mg/day) prevented kidney stone formation. The aim of this study was to determine whether high doses of boron have an anti-urolithiatic or antioxidant effect on nephrolithiasis in an experimental rat model...

Uric acid nephrolithiasis (UAN) is an increasingly common disease in ethnically diverse populations and constitutes about 10% of all kidney stones. Metabolic syndrome and diabetes mellitus are accounted amongst the major risk factors for UAN, together with environmental exposure, individual lifestyle habits and genetic predisposition. The development and overt manifestation of UAN appears to stem on the background of insulin resistance, which acts at the kidney level by reducing urinary pH, thus hampering the ability of the kidney to generate renal ammonium in response to an acid load...

Urinary stones are complex mineralogical formations in the urinary system often impairing the kidney function. Several studies have attempted to understand the mechanisms of stone formation and growth; however, it remains to be fully explored. Here, we present a detailed investigation on the morphological and mineralogical characterizations of urinary stones. Structural properties of different types of urinary stones were done by X-ray diffraction (XRD), Fourier-transform infrared spectroscopy (FTIR), and field-emission scanning electron microscope (FE-SEM) analyses...

The concept of adipose tissue as an organ unto itself represents a new medical construct; already differences in the volume of perirenal fat around a tumor-bearing kidney have been described. We hypothesized that renal calculi may have similar impact on perirenal fat or alternatively abnormalities in urinary metabolites may be the result of perirenal fat affecting renal metabolism and subsequent stone formation. Accordingly, we conducted a study utilizing three-dimensional imaging software to evaluate perirenal fat volume (PFV) in patients with nephrolithiasis...

Urate is a cause of gout, kidney stones, and acute kidney injury from tumor lysis syndrome, but its relationship to kidney disease, cardiovascular disease, and diabetes remains controversial. A scientific workshop organized by the National Kidney Foundation was held in September 2016 to review current evidence. Cell culture studies and animal models suggest that elevated serum urate concentrations can contribute to kidney disease, hypertension, and metabolic syndrome. Epidemiologic evidence also supports elevated serum urate concentrations as a risk factor for the development of kidney disease, hypertension, and diabetes, but differences in methodologies and inpacts on serum urate concentrations by even subtle changes in kidney function render conclusions uncertain...

BACKGROUND AND OBJECTIVES: Kidney stones are associated with future development of hypertension, diabetes, and the metabolic syndrome. Our objective was to assess whether stone formation before pregnancy was associated with metabolic and hypertensive complications in pregnancy. We hypothesized that stone formation is a marker of metabolic disease and would be associated with higher risk for maternal complications in pregnancy. DESIGN, SETTING, PARTICIPANTS, & MEASUREMENTS: We conducted a retrospective cohort study of women who delivered infants at the Massachusetts General Hospital from 2006 to 2015...

Medullary sponge kidney (MSK) is a cause of nephrocalcinosis, associated with hematuria, renal colic, pyelonephritis. There are rare and atypical MSK cases characterized by chronic severe pain (CP), whose features are unknown, in particular the relationship with the stone disease activity. This study analyzes a cohort of MSK-CP patients belonging to three North-America self-support Facebook groups. Patients had to self-administer an on-line questionnaire (on intensity, progression and MSK-associated conditions, stone-related disease, pain features, drug use), the Brief Pain Inventory, the Fatigue Severity Score, and Wisconsin Quality of Life (WQL) in stone formers questionnaires...

BACKGROUND: Various genetic and environmental factors are involved in urolithiasis. The 2 most common metabolic abnormalities are the increase in urinary calcium and low urinary citrate excretion. The ratio calculated between the concentrations of both substances is a good risk marker for the formation of calcium stones. OBJECTIVES: To determine whether the risk of urinary calcium stone formation changes throughout the day in the same patient. METHODS: We studied 56 children (23V, 33M) to check if they had prelithiasis...

Osteoporosis and fragility fractures are important social and economic problems worldwide and are due to both the loss of bone mineral density and sarcopenia. Indeed, fragility fractures are associated with increased disability, morbidity and mortality. It is known that a normal calcium balance together with a normal vitamin D status is important for maintaining well-balanced bone metabolism, and for many years, calcium and vitamin D have been considered crucial in the prevention and treatment of osteoporosis...
