A Abou-Elela
An in-depth comprehension of the epidemiology as well as pathophysiology of uric acid urolithiasis is important for the identification, treatment, and prophylaxis of calculi in these patients. Persistently low urinary pH, hyperuricosuria, and low urinary volume are the most important factors in pathogenesis of uric acid urolithiasis. Other various causes of calculus formation comprises of chronic diarrhea, renal hyperuricosuria, insulin resistance, primary gout, extra purine in the diet, neoplastic syndromes, and congenital hyperuricemia...

Hyperoxaluria can result in oxalate nephropathy with intratubular calcium oxalate crystallization and acute tubular injury. Primary inherited enzymatic deficiency or secondary causes such as excessive dietary intake, enteric increased absorption, or high doses of vitamin C, which is metabolized to oxalate, may underlie hyperoxaluria and oxalate nephropathy. We report a case of acute kidney injury due to oxalate nephropathy in a patient using chelating therapy with oral ethylenediamine tetra acetic acid (EDTA), intravenous supplementation with vitamin C, and chronic diarrhea and discuss the potential kidney damage these factors can cause in particular settings...

Food protein-induced enterocolitis syndrome is a nonimmunoglobulin E mediated gastrointestinal food hypersensitivity that manifests as profuse, repetitive vomiting, pallor and hypotonia, often with diarrhea leading to severe dehydration and lethargy (sepsis-like symptoms) in the acute setting. An oral food challenge is sometimes performed to confirm the diagnosis and treatment consists of elimination of the food trigger(s) from the diet. We report a case of a 3-monthsold infant with several episodes of food protein-induced enterocolitis syndrome after taking infant formula milk with tolerance of another trademark...

Human caliciviruses (HuCVs) have been recognized as a major cause of sporadic viral diarrhea in children, among which norovirus genotype GII.4 is the most prevalent genotype. Stool and saliva samples were collected from 295 children with acute diarrhea and 150 asymptomatic children at a hospital in China. The HuCV detection rate was 10.85% (32/295) among the children with acute diarrhea, and all of these 32 children were either HBGA secretors (12/32) or partial secretors (20/32). HuCV was detected in two (1...

Group A rotavirus (RVA) acute gastroenteritis (AGE) is a common cause of severe childhood diarrhea. The dominant circulating RVA genotypes in a given region may vary between and within the geographic regions and from year to year. Our cross-sectional study was designed to determine the burden of RVA genotypes among children with AGE admitted to referral Children Hospital at Egypt prior to implementation of the vaccine. Stool samples with clinico-epidemiological data were collected from 92 children ≤ 3 years-old with AGE...

Rotavirus vaccines have been successful in controlling severe diarrhea and have decreased deaths of young children globally. Rotarix and RotaTeq are the two currently available live-attenuated rotavirus vaccines. The vaccine virus can grow in a recipient's gut and spread from the vaccinee to naïve individuals. The potential for the emergence of revertant viruses is a concern with live-attenuated vaccines. We identified a previously healthy infant with severe acute gastroenteritis that was positive for rotavirus in a non-endemic season...

Noroviruses have been recognized as the leading cause of epidemic and sporadic gastroenteritis since the advent of molecular diagnostic technique. They have been documented in 5-31% of pediatric patients hospitalized with gastroenteritis. Although norovirus gastroenteritis is typically mild and self-limited, it causes severe, but sometimes fatal, conditions in the vulnerable population such as immunocompromised patients, young children, and the elderly. Bowel perforation due to norovirus infection is rare. We report a case of small bowel perforation with norovirus gastroenteritis in the infant with Down syndrome during the hospitalization with pneumonia...

BACKGROUND: The problem of intermittent piped water supplies that exists in low- and middle-income countries is particularly severe in the slums of sub-Saharan Africa. However, little is known about whether there is deterioration of the microbiological quality of the intermittent piped water supply at a household level and whether it is a factor in reducing or increasing the occurrence of acute diarrhea among under-five children in slums of Addis Ababa. This study aimed to determine the association of intermittent piped water supplies and point-of-use (POU) contamination of household stored water by Escherichia coli (E...

Oral cholera vaccination was used as part of cholera control in Haiti, but the vaccine does not provide complete protection. We conducted secondary data analyses of a vaccine effectiveness study in Haiti to evaluate risk factors for cholera among cholera vaccine recipients. Individuals vaccinated against cholera that presented with acute watery diarrhea and had a stool sample positive for Vibrio cholerae O1 were included as cases. Up to four vaccinated individuals who did not present for treatment of diarrhea were included as controls for each case, and matched by location of residence, enrollment time, and age...

Food protein-induced enterocolitis syndrome (FPIES) is a potentially severe presentation of non-IgE-mediated gastrointestinal food allergy (non-IgE-GI-FA) with heterogeneous clinical manifestations. Acute FPIES is typically characterized by profuse vomiting and lethargy, occurring classically 1-4 hours after ingestion of the offending food. When continuously exposed to the incriminated food, a chronic form has been described with persistent vomiting, diarrhea, and/or failure to thrive. Although affecting mainly infants, FPIES has also been described in adults...

Diarrheal disease is a leading cause of death among young children worldwide. As rates of acute diarrhea (AD; 1-6 days duration) have decreased, persistent diarrhea (PD; > 14 days duration) accounts for a greater proportion of the diarrheal disease burden. We describe factors associated with the duration of moderate-to-severe diarrhea in Kenyan children < 5 years old enrolled in the Global Enteric Multicenter Study. We found 587 (58%) children experienced AD, 360 (35%) had prolonged acute diarrhea (ProAD; 7-13 days duration), and 73 (7%) had PD...

AbstractRotavirus commonly causes diarrhea in children, leading to hospitalization and even death. Rapid diagnostic tests are feasible alternatives for determining rotavirus outbreaks in refugee camps that have inadequate laboratory capacity. We evaluated the field performance of ImmunoCard STAT!(®) Rotavirus (ICS-RV) in Dadaab Refugee Camp and at the Kenya-Somalia border. From May to December 2014, we prospectively enrolled children aged < 5 years hospitalized with acute diarrhea, defined as ≥ 3 episodes of loose stool in 24 hours for < 7 days...

High-dose loperamide is often used for the acute management of chemotherapy-induced diarrhea, with a maximum daily dosing of up to 24 mg. Recently, the US Food and Drug Administration has issued a warning that loperamide can cause rare serious cardiac events, including QT prolongation, torsades de pointes, cardiac arrest and death. Most events were reported in patients taking very high doses for an extended period of time. Daily intake ranged from 64 mg to 1600 mg, often continuously for weeks or months...

Rotavirus (RV) infection causes acute, watery dehydrating diarrhea and even death in infants and other young animals, resulting in a severe economic burden; however, little is known about the innate immune mechanisms associated with RV infection. Dendritic cells (DCs), which are professional antigen-presenting cells (APCs), serve as a bridge connecting the innate and adaptive immune system. In this study, the interaction between murine bone marrow-derived DCs (BMDCs) and porcine rotavirus (PRV) was investigated in vitro...

Kawasaki disease (KD) is an acute febrile vasculitis of an unknown cause. It affects children <5 year of age, even if cases over 5 years old have been also reported. It is the commonest cause of acquired heart diseases in children which may lead to serious morbidity and mortality. The complications and mortality increase when the diagnosis is delayed. One of the main reasons leading to delayed diagnosis and consequent delayed treatment is the unusual presentation of KD. Its unusual manifestations have been increasingly reported to jeopardize the timely diagnosis and proper treatment...
