Spot urine samples to estimate 24-hour urinary calcium excretion in school-age children.

Urinary calcium/creatinine ratio (UCa/Cr) on a single spot urine sample is frequently used in children to evaluate calciuria, but its accuracy to estimate 24-h urinary calcium excretion (24hUCa) has not been properly assessed. We analyzed the correlation between UCa/Cr in various spot samples and 24hUCa among healthy children. A 24-h urine specimen and three spot urine samples (evening, first, and second morning) were collected in a convenience sample of children aged 6 to 16 years (n = 101).

Monitoring caffeine intake in children with a questionnaire and urine collection: a cross-sectional study in a convenience sample in Switzerland.

Purpose: The objectives of this study were (1) to estimate caffeine intake and identify the main sources of intake using a dietary questionnaire, (2) to assess 24-h urinary excretion of caffeine and its metabolites, and (3) to assess how self-reported intake estimates correlates with urinary excretion among children in Switzerland.

Methods: We conducted a cross-sectional study of children between 6 and 16 years of age in one region of Switzerland. The participants filled in a dietary questionnaire and collected a 24-h urine sample.

Urine Spot Samples Can Be Used to Estimate 24-Hour Urinary Sodium Excretion in Children.

Background: The gold standard to assess salt intake is 24-h urine collections. Use of a urine spot sample can be a simpler alternative, especially when the goal is to assess sodium intake at the population level. Several equations to estimate 24-h urinary sodium excretion from urine spot samples have been tested in adults, but not in children.

Estimation of salt intake and excretion in children in one region of Switzerland: a cross-sectional study.

Purpose: Salt intake among children in Switzerland is unknown. The objectives of this study were to determine salt excretion and to identify the main dietary sources of salt intake among children in one region of Switzerland.

Methods: We conducted a cross-sectional study using a convenient sample of children 6-16 years of age in Valais, Switzerland, between 2016 and 2018.

[Ritual circumcision : a society challenge].

Male circumcision is one of the most common surgical procedure in the world. At the world level, 30 % of the men are circumcised. The reasons of circumcisions are ritual for 97 %.

Total laparoscopic excision of retroperitoneal cystic lymphangioma.

Retroperitoneal cystic lymphangioma is a rare benign tumor of the retroperitoneal lymphatics that usually manifests in infancy. If surgical excision is used in treatment, it needs to be as complete as possible to reduce the risk of recurrence. Two pediatric patients, an 18-month-old girl and a 4-yearold boy, underwent laparoscopic excision of symptomatic retroperitoneal cystic lymphangiomas.

Ingestion of magnets: innocent in solitude, harmful in groups.

Foreign body ingestion is frequent in children and generally associated with little morbidity. However, some foreign bodies are innocent when ingested as a single object, but may have harmful effect if numerous. We report a 9-year-old girl who swallowed 5 magnets, causing acute intestinal obstruction.

[Management of simple cranial injuries and minor cranio-cerebral injuries in children].

Owing to the frequent occurrence of minor head injuries in their daily practice, pediatricians and primary care physicians have a constant concern about their management. Evaluation of a neurotraumatised children must take account of the epidemiological, anatomical, pathophysiological and clinical specificity of each age class. Recent publications of the American Academy of Pediatric, with evidence based medicine review of the literature and experts consensus have permitted to define precise guidelines for the management of children over and below 2 years of age.

Peritoneal schistosomiasis: an unusual laparoscopic finding.

Laparoscopic surgery is now a common procedure for the cure of appendicitis. Unexpected other laparoscopic findings can be a diagnostic challenge. The authors present a case in which, in addition to typical appendicitis, multiple whitish nodules were found diffusely on the peritoneal surfaces suggesting a differential diagnosis including miliary tuberculosis and carcinoma metastases.
