High blood pressure (BP) or hypertension is a well known risk factor for developing heart attack, stroke, atrial fibrillation and renal failure. Although in the past hypertension was supposed to develop at middle age, it is now widely recognized that it begins early during childhood. As such, approximately 5-10% of children and adolescents are hypertensive. Unlike that previously reported, it is now widely accepted that primary hypertension is the most diffuse form of high BP encountered even in paediatric age, while secondary hypertension accounts just for a minority of the cases. There are significant differences between that outlined by the European Society of Hypertension (ESH), the European Society of Cardiology (ESC), and the last statement by the American Academy of Pediatrics (AAP) concerning the BP cut-offs to identify young hypertensive individuals. Not only that, but the AAP have also excluded obese children in the new normative data. This is undoubtedly a matter of concern. Conversely, both the AAP and ESH/ESC agree that medical therapy should be reserved just for nonresponders to measures like weight loss/salt intake reduction/increase in aerobic exercise. Secondary hypertension often occurs in aortic coarctation or chronic renal disease patients. The former can develop hypertension despite early effective repair. This is associated with significant morbidity and is arguably the most important adverse outcome in about 30% of these subjects. Also, syndromic patients, for example those with Williams syndrome, may suffer from a generalized aortopathy, which triggers increased arterial stiffness and hypertension. This review summarizes the state-of-the-art situation regarding primary and secondary paediatric hypertension., (Copyright © 2022 Italian Federation of Cardiology - I.F.C. All rights reserved.)

: The recent outbreak of 2019 severe acute respiratory syndrome coronavirus-2 is having major repercussions on healthcare services provision in Italy and worldwide. Data suggest the virus has a strong impact on the cardiovascular system, and cardiac imaging will play an important role in patients affected by coronavirus disease-2019. Although paediatric patients are mildly affected, they represent a clear accelerator in spreading the virus, and healthcare workers are at higher risk of infection. The aim of this position paper is to provide clinical recommendation regarding the execution of imaging investigations for the cardiac diagnostic work-up of paediatric patients with suspected or confirmed infection.

Background: Left ventricular noncompaction cardiomyopathy (LVNC) is associated with poor clinical outcome in childhood. Standard diagnostic criteria are still controversial, especially in young patients. Recent studies in adults demonstrated that left ventricular (LV) twist is abnormal in LVNC, but it has not been investigated in pediatric patients to date. Our aim was to assess LV cardiac mechanics, LV twist, and the prevalence of rigid body rotation, using 2-dimensional speckle tracking echocardiography, in young patients with LVNC and LV hypertrabeculation., Methods: Forty-seven children (age range: 0-18 years) were assessed for suspected LVNC. All patients underwent 2-dimensional speckle tracking echocardiography and cardiovascular magnetic resonance imaging at 1.5 Tesla (T). Twenty-three patients fulfilled the cardiovascular magnetic resonance imaging diagnostic criteria for LVNC (LVNC group), while the remaining 24 did not and were included in the LV hypertrabeculation group. Forty-seven age- and sex-matched healthy volunteers were used as controls., Results: The average LV twist was significantly reduced in LVNC compared with control and LV hypertrabeculation. Rigid body rotation was recognized in 13 (56%) children with LVNC and in 1 (4%) child with LV hypertrabeculation and a strong family history for LVNC. Multivariable analysis demonstrated that LV twist is an independent predictor of LVNC ( P=0.006; coefficient=0.462). The receiver operating characteristics curve showed that LV twist had optimal predictive value to discriminate patients with LVNC (cutoff value <5.8°; sensitivity, 82%; specificity, 92%; area under the curve=0.914)., Conclusions: LV twist has good predictive value in diagnosing LVNC in young patients. Our findings strongly support the routine use of 2-dimensional speckle tracking echocardiography in the evaluation of young patients with suspected LVNC.

Objective: Voluntary HIV testing and counseling (VTC) has been shown to reduce the incidence of HIV in cohabiting couples who now represent the majority of new infections in many African cities. Community and client perceptions of a 1-day voluntary testing and counseling program in Lusaka, Zambia, were assessed, and a rapid HIV-testing algorithm was evaluated for VTC centers., Methods and Design: Between May 1995 and June 1996, outreach workers distributed written invitations door to door. The 1-day program was held 6 days/week including weekends. Transport, child care and lunch were provided. Community and client surveys followed in July 1996., Results: Over 3500 couples married for a median of 4-5 years requested testing: 23% were HIV+/+, 57% were HIV-/- and 20% were discordant with one HIV+ and one HIV- partner. Sixty-eight per cent of couples surveyed had made the decision to be tested before attending the 1-day program and 80% had not previously known where to obtain HIV testing. Knowledge that couples could show discordant results rose from 29 before to 88% after pretest counseling. Clients reported high levels of satisfaction with the services and 90 out of 99 (92%) preferred to receive their results the same day. Clients at another center who waited 10 days for their results reported more fear, and 19 out of 31 (61%) would have preferred to get their results the same day. Over 99% of those who attended the program thought active promotion of voluntary HIV testing in the community was a positive thing, as did 90% of those who were invited but did not attend. Sensitivity and specificity of the rapid test algorithm were both 99.4% in this setting., Conclusions: Active promotion of voluntary HIV testing and counseling in couples is needed to reduce the spread of HIV in high-prevalence areas. The use of rapid, on-site HIV testing allows clients to receive result-specific counseling in a single visit. Ongoing quality control of a subset of samples at an outside laboratory is essential.
