Carnitine deficiency in children and adolescents with type 1 diabetes.

Carnitine is essential for the lipid and carbohydrate metabolism, and proper metabolic control in type 1 diabetes has potential impact on long-term complications. The plasma total, free, and acylcarnitine levels in 47 children and adolescents with type 1 diabetes were determined by a radioisotopic assay and compared to the values of a series of anthropometric measurements and metabolic parameters, including blood glycosylated hemoglobin Alc, serum cholesterol and triglycerides, and urine microalbumin levels. Plasma values for total, free, and acylcarnitine were 30.

Quantitative ultrasound measurements in children and adolescents with: type 1 diabetes.

The aim of the current study was to evaluate bone status at the radius and phalanx in children and adolescents with type 1 diabetes by using quantitative ultrasound (QUS) measurements. Thirty pediatric patients, 16 male and 14 female, with type 1 diabetes of duration of 5 to 177 months and mean (+/- SD) age 11.3 +/- 4.

Epidemiology of childhood type I diabetes in Crete, 1990-2001.

Aim: To study the epidemiological patterns of childhood-onset type I diabetes in Crete, Greece.

Methods: The incidence (new cases per 100,000 per year) from 1990 to 2001 was determined in the population of Crete < or = 14 y of age.

Results: A total of 89 cases was ascertained.

Application of a ketogenic diet in children with autistic behavior: pilot study.

A pilot prospective follow-up study of the role of the ketogenic diet was carried out on 30 children, aged between 4 and 10 years, with autistic behavior. The diet was applied for 6 months, with continuous administration for 4 weeks, interrupted by 2-week diet-free intervals. Seven patients could not tolerate the diet, whereas five other patients adhered to the diet for 1 to 2 months and then discontinued it.

Ochrobactrum anthropi bacteraemia in immunocompetent children.

Ochrobactrum anthropi is an emerging pathogen in immunocompromised patients but infections with the bacterium have very rarely been documented in normal hosts. We report the characteristics of O. anthropi bacteraemia in 11 immunocompetent children, aged 2 months to 7 y, hospitalized in a general hospital during a 5-y period.

Rickettsia typhi infection presenting as subacute meningitis.

We report two children with Rickettsia typhi infection presenting with mild central nervous system manifestations and pleocytosis in cerebrospinal fluid. Murine typhus should be included in the differential diagnosis of meningoencephalitis in children who are residents of endemic areas.

Burden of respiratory syncytial viral infections on paediatric hospitals: a two-year prospective epidemiological study.

This study was designed to prospectively investigate the hospitalisation patterns for respiratory syncytial virus (RSV) disease in children up to 2 years of age, both healthy full-term children and high-risk children. The aim was to evaluate children hospitalised for a respiratory tract infection in four regions and seven paediatric hospital departments or clinics in Greece and to estimate the burden of RSV disease on paediatric hospital beds, as well as to determine the target high-risk age group over two consecutive respiratory infection seasons. Among a total of 1,710 children, the overall prevalence of RSV disease was 33.

Rickettsia typhi infection in childhood.

Unlabelled: Rickettsia typhi infection (murine typhus) is generally underdiagnosed in childhood, as clinical presentations are often non-specific. We present the manifestations in nine children hospitalized in the Department of Paediatrics of the University Hospital, Heraklion, Crete, over a 3-y period from 1998 to 2000. Titres > 1:400 for IgM and >1:960 for IgG and/or a fourfold increase in a second sample were considered strongly suggestive of acute infection.

Invasive Salmonella virchow infection in childhood.

Salmonella virchow is generally considered to be one of the less invasive non-typhoidal Salmonellae species; however, several invasive cases have previously been reported. We report 3 cases of otherwise healthy children with S. virchow bacteraemia, monoarthritis and prevertebral abscess, only 1 of whom had previously had gastroenteritis.

Transverse myelitis associated with herpes simplex virus infection.

The case of an otherwise healthy 6-year-old boy with symptoms and signs of acute transverse myelitis is presented. The diagnosis was confirmed by magnetic resonance imaging. An episode of gingivostomatitis had preceded, and serology indicated herpes simplex virus type 1 infection.

Facial nerve palsy associated with Rickettsia conorii infection.

Facial nerve palsy has been occasionally attributed to infectious agents, but Rickettsiae species have not been documented as causative agents. We report two adolescent girls with facial nerve palsy and serological evidence of R conorii infection. These cases indicate that rickettsioses should be included among the causes of facial nerve palsy, particularly in endemic areas.

Mucus plugging as a cause of acute lobar overdistension.

Acute lobar overdistension in children is usually indicative of foreign body aspiration, especially when a history of a choking episode is recalled. An unusual presentation of asthma as recurrent overdistension of the left lung in a toddler is described. The child had undergone two consecutive negative bronchoscopies with a presumptive diagnosis of foreign body aspiration; however, it was only the antiasthmatic treatment that resulted in an excellent outcome.

A local cluster of achalasia in a province of Crete.

Achalasia has a largely obscure aetiology and is uncommon in childhood. We report three cases of otherwise well children, residents of a small province of Crete, two of them female cousins. This cluster probably indicates an autosomal recessive trait of inheritance.

An unusual case of lead poisoning in an infant: nursing-associated plumbism.

Lead poisoning remains a common environmental threat for children today. The majority of cases of lead poisoning are caused by oral intake of lead dust or lead-containing paint flakes and thus occur during the second and third years of life. An unusual case of severe lead poisoning in a breast-feeding infant girl is here presented; the source proved to be a nipple shield made of a lead-containing metal.

Effect of hydrochlorothiazide on renal hypercalciuria.

The long-term effect of hydrochlorothiazide (HCT) was studied in 30 children (17 boys and 13 girls), aged 4-13 years (mean 7.6 +/- 3.4), with renal hypercalciuria (HCU) for a period of 2.

The diagnosis of hypercalciuria in children.

Calcium loading tests were performed in 21 children with hypercalciuria, haematuria and/or nephrolithiasis and 10 control subjects. Comparisons of 24-h calcium excretion before and after loading were evaluated rather than fasting urinary calcium to urinary creatinine ratio. The differences in calcium excretion before and after loading clearly distinguished absorptive from renal hypercalciuria.

A simple index for initiating transfusion treatment in thalassaemia intermedia.

In order to develop an objective test for discriminating between patients with thalassaemia intermedia requiring blood transfusion, and those not likely to require transfusion the medullary width (MW) in the midpoint of the second left metacarpal and the bone mass were measured in 34 normal children and in 37 patients. In patients, blood haemoglobin (Hb) and serum ferritin concentration were measured and cephalofacial deformities (CFD) were scored. The mean values of MW were 0.

Renal handling of phosphate in the first six months of life.

Indices of renal excretion and reabsorption of phosphate were studied in 20 neonatal infants, 20 infants aged 3 months, and 20 infants aged 6 months. All subjects were normal and were fed a modified formula enriched with vitamin D. In neonatal infants all indices of phosphate excretion were found to be significantly lower and those of phosphate reabsorption significantly higher than in older infants.
