Children with heterozygous familial hypercholesterolemia (heFH) are prone to premature atherosclerosis. Vascular endothelial dysfunction may predict increased cardiovascular risk in children with heFH. The aim of this study was to assess for early functional and structural vascular changes in children with heFH. This cross-sectional study included 30 children with heFH (mean age 12 years) and 30 age- and sex-matched controls. Brachial artery flow-mediated dilation (FMD), carotid intima-media thickness (cIMT), carotid-femoral pulse wave velocity, and large- and small vessel compliance were measured noninvasively. HeFH children exhibited significantly greater total and LDL cholesterol, apolipoprotein B, and lipoprotein (a) levels ( p < 0.05 for all) and lower FMD (6.23 ± 3.88 vs. 9.46 ± 4.54 %, p < 0.004) compared with controls. When children were divided in age subgroups, FMD was found to be significantly decreased in heFH compared with control subjects only in ages >10 years ( p < 0.05). However, FMD was found to be similarly impaired in heFH children in all age subgroups (two-way analysis of variance, p = 0.39). No differences in other vascular function indices were found. In heFH patients, but not in controls, FMD was inversely correlated with cIMT ( r = −0.378, p = 0.036). In conclusion, endothelial dysfunction occurs early in heFH children indicating an increased risk for premature cardiovascular disease and reflecting probably the need for early initiation of anticholesterolemic treatment. Decreased FMD is detected before structural atherosclerotic changes occur. [ABSTRACT FROM AUTHOR]

Blue rubber bleb nevus syndrome (BRBNS) is a rare disorder characterized by venous malformations usually affecting the skin and the gastrointestinal tract. These skin haemangiomas are present at birth and deteriorate as the body grows, causing primarily cosmetic problems. The haemangiomas of the gastrointestinal tract may appear later in life and may bleed, causing chronic anaemia, or may present with severe complications such as rupture, intestinal torsion, and intussusception. Other organs may also be involved. This article describes a 13-year-old boy with multiple haemangiomas of the skin, the mucous membranes, and the gastrointestinal tract, which caused anaemia and ileoileic intussusception. In this patient, the nervous system was significantly affected with a haemangioma of the left occipital lobe, with complications of stroke. He also had multiple paravertebral heamangiomas, which caused pressure signs and symptoms. This boy suffered from complex partial and generalized seizures and cerebral palsy. Multiple skeletal anomalies were also present from birth. In the relevant literature, this is the first case of BRBNS with simultaneous neurological and skeletal involvement. Such cases should be recognized early, as they can lead to serious multiple health problems and handicaps. [ABSTRACT FROM AUTHOR]

In the present study 19 Greek Caucasian children with systemic lupus erythematosus (SLE), onset before the age of 16, were followed up for 1-12 years (mean 5.6 yrs.). Diagnosis was determined early in 14 patients and delayed by 2 to 6 years in 5. The clinical manifestations and laboratory findings did not differ significantly from those reported in adults with lupus. The major organ system involvement at onset and early course were skin and joints (80%) followed by kidneys (42%). During the course of the disease 26% of the children developed central nervous system (CNS) involvement. All the patients were treated with steroids and/or cytotoxic drugs in severe uncontrolled progressive disease. At the mean 5.6 years follow-up most patients were in remission on small doses of steroids; one patient still presents signs of active lupus nephritis and one patient died from sepsis. All the patients with CNS involvement recovered without permanent CNS residue. [ABSTRACT FROM AUTHOR]

Subacute cutaneous lupus erythematosus (SCLE) has been described in adults in the last decade and represents a particular homogenous subgroup in which the skin lesions can be distinguished from scarring discoid lupus lesions both on a morphologic and histopathologic basis. This entity, however, seems to be very uncommon in childhood. In the present study we describe the clinical, immunological and histopathologic characteristics of a young girl who, at the age of 3, developed SCLE. [ABSTRACT FROM AUTHOR]

A 12-year-old boy who developed primary Sjogren syndrome and a girl, whose diagnosis of secondary Sjogren syndrome was established at the age of 3, are reported. The importance of some unusual manifestations at disease onset and possible differences in expression between children and adults are briefly discussed. [ABSTRACT FROM AUTHOR]
