Abstract Purpose Insufficient and poor sleep patterns are common among adolescents worldwide. Up to now, the evidence on adolescent sleep has been mostly informed by country-specific studies that used different measures and age groups, making direct comparisons difficult. Cross-national data on adolescent sleep that could inform nations and international discussions are lacking. We examined the sleep patterns of adolescents across 24 countries and by gender, age, and affluence groups. Methods We obtained sleep data on 165,793 adolescents (mean age 13.5 years; 50.5% girls) in 24 European and North American countries from the recent cross-sectional Health Behaviour in School-aged Children sur…

The anatomy of the heart in the sonogram. A comparison between anatomic and ultrasonic cross-section.

1977

Cardiac sonography has only recently been introduced as a diagnostic procedure. In order to facilitate the interpretation and evaluation of the ultrasonic cardiac cross-section displayed by this two-dimensional technique, we performed anatomic cross-sections corresponding to ultrasonic cross-sections. The ultrasonic cross-sectional images were taken from children with a real-time-motion scanner. The anatomic cross-sections were taken from adult hearts. Two ultrasonic transverse cross-sections are compared with the two corresponding anatomic cross-sections and three ultrasonic longitudinal cross-sections with one corresponding anatomic cross-section. The direct comparison between anatomic an…

Is Nephron Sparing Surgery Justified in Wilms Tumor With Beckwith-Wiedemann Syndrome or Isolated Hemihypertrophy?

2016

Background Patients with Beckwith–Wiedemann syndrome (BWS) or isolated hemihypertrophy (HH) treated for a Wilms tumor (WT) carry an increased risk of developing metachronous lesion. There are no guidelines on precise indications for nephron sparing surgery (NSS) in unilateral WT (UWT). The objective of this retrospective study was to delineate the indications of NSS in patients with BWS/HH treated for WT and to evaluate their outcome. Procedure All cases of BWS/HH treated for a WT according to SIOP protocols from 1980 to 2013 were reviewed. Patients were divided into two groups (G): isolated UWT (G1) and bilateral lesions (G2) with two subgroups: bilateral tumors suspected of malignancy (G2…

Acid-Base Balance after Continent Urinary Diversion in Childhood – Risk of Imbalance Despite Medication

2010

Purpose Continent urinary-intestinal diversion can lead to alterations of the acid-base balance, acutely and chronically, the latter possibly causing bone demineralization. Annual check-ups have therefore been recommended for decades. Material and Methods At our institution, 89 children underwent continent urinary diversion by ileocecal pouch or bladder substitution between 1984 and 2006. In 58 of these patients (age 3-17 y., median 13.9 y.), we performed a minimum of 3 (range 3-23, median 6.2) consecutive annual blood-gas analyses over a follow-up period of up to 23 years (median 11.0) after surgery. At a base excess (BE) (as marker of the acid-base-balance) value below -2.5 mmol/l, treatm…

Vitamin B12 Deficiency in Children after Continent Urinary Diversion by Mainz Pouch Technique

2010

Purpose MAINZ pouch I urinary diversion provides a high-capacity, low-pressure reservoir. The use of terminal ileum can cause a decrease of vitamin B12 levels. Symptoms caused by vitamin B12 deficiency are rare, but some are irreversible, therefore annual check-ups are recommended. In this study the vitamin B12 levels in the above patients were analyzed in retrospect. Material and Methods The ileocecal segment was used for urinary tract reconstruction in > 80 children ≤17 years of age. B12 levels were determined at various time points within up to 21 years after surgery in 63 patients (8 with ileocecal bladder substitution, 55 continent cutaneous diversion). B12 values below 200pg/ml were c…

Radical Surgery in Children and Adolescents with Rhabdomyosarcoma of the Lower Urinary Tract Using Orthotopic Bladder Substitution and Heterotopic Ur…

2008

Abstract Purpose Children with rhabdomyosarcoma(RMS)of the bladder/prostate can be treated by radical or organ sparing surgery both in combination with chemotherapy ± radiation therapy. In this retrospective study we analyzed the outcome with special attention to radical surgery and urinary diversion (UD). Material and Methods 24/32 patients with RMS of the genitourinary tract had RMS of the bladder (n=14) or prostate (n=10). 8 patients were stage II, 11 stage III and 5 stage IV. In 18/24 with RMS of the bladder/prostate, radical surgery and urinary diversion was performed. 3 had chemotherapy only, 2 in combination with radiotherapy. One patient underwent partial cystectomy. For UD: uretero…

Arteriovenous fistula of the vertebral artery in a female infant with hypotonia and cephalocorporal disproportion

2010

Background:  Congenital arteriovenous fistulas are exceptional in childhood and imply a therapeutic challenge. Case report: A 9-month-old female infant was studied for cephalocorporal disproportion, hypotonia, progressive muscular atrophy and hyperreflexia. Computed tomography of the brain and electroencephalography were normal. Electromyographic patterns suggested proximal myopathic involvement. A continuous murmur with systolic reinforcement was audible in the neck. Angioresonance detected intracranial aneurysmal dilatations behind the bulbo-medullary junction and cerebral panangiography evidenced a direct vertebrovertebral fistula with extra- and intra-cranial varices and extreme medulla…
