RESUMO
The current outbreak of COVID-19 raging globally is taking a heavy toll on the adult population, with a rapidly growing number of newly infected and critically ill patients. However, to date, mortality rate among children is low as they mostly suffer from a mild disease. Yet, other more routinely encountered childhood diseases do not stand still and continue to be the main share of pediatricians' everyday challenges. Here we describe a case series of routinely seen pediatric diseases with delayed diagnosis due to different aspects of what we call "Corona-phobia". These cases were easily collected within a 1-week period which implies that this is a more widespread phenomenon.In conclusion, this raises the possibility that measures taken to mitigate this pandemic may be more damaging to children overall than the virus itself. We believe that pediatricians as well as policy makers should take this important aspect into consideration. What is Known: ⢠COVID-19 manifests as a mild disease in most children; however, children are an important reservoir and may become spreaders of the disease. ⢠Social distancing and isolation are important tools in mitigating COVID-19 transmission. What is New: ⢠This case series describes 7 cases with delayed diagnosis of every-day pediatric diseases that were not caused by COVID-19 but were highly influenced by different aspects of "Corona-phobia". ⢠Our objective is to highlight the possibility that measures taken to mitigate this pandemic may lead to a substantial delay in the diagnosis of other non-COVID-19 related diseases.

PURPOSE: Boys' lower-body muscle power generation (PO) recovers faster than men's following intensive exercise. The purpose of this study was to examine whether boys differ from adult men in recovering from upper-body muscle power generation following intensive exercise. METHODS: Fifteen prepubertal boys (M ± SD age 10.6 ± 1.0 years) and 13 men (31.1 ± 5.0 years) performed two upper-body Wingate Anaerobic Tests (WAnT), separated by either 2-min or 10-min recovery intervals. WAnT parameters, pre-and post-WAnT heart rates (HR), and blood lactate ([La]) were measured during recovery from the WAnTs. RESULTS: Boys' mean power (MP) of the repeated WAnT (WAnT2) following 2- and 10-min recoveries was 97.3 ± 7.2% and 99.4 ± 3.9%, respectively, compared to MP of the first test (WAnT1) (p > 0.05 for both tests). In contrast, in men's MP of the WAnT2 following the 2-min recovery, was significantly lower than that of the WAnT1 (84.4 ± 6.7%, p = 0.0001). While boys' and men's HR recovery after 2 min differed significantly (p = 0.046), no between-group differences were found following the 10-min recovery. Peak [La] in boys was 37-44% lower than that in men (p = 0.002). CONCLUSIONS: The faster recovery of PO in boys after supra-maximal upper-body exercise is partially explained by the lower power generated by boys, attributed in part to a lower anaerobic capacity and to the greater relative contribution of aerobic processes to performance and recovery from anaerobic-type tasks. Further research is needed to determine the physiologic, neurologic and biochemical basis of the rapid muscle power recovery in children.

AIM: Improved communication with staff during a child's hospitalisation is an important determinant of family satisfaction. We examined whether displaying staff photographs in prominent locations would help children and their parents or guardians to recognise staff and whether this enhanced identification would improve parental satisfaction with their child's hospitalisation. METHODS: No photographs were displayed during the first part of the study. During the second part of the study, staff photographs were placed in prominent locations throughout the paediatric ward. Parents filled in a satisfaction questionnaire on discharge, and the children and their parents were asked how many staff members they could name. RESULTS: The children named a significantly larger number of staff members in phase two than phase one, while the parents' score was unchanged. Overall parental satisfaction was significantly higher in phase two. The parent's age, the duration of the child's hospitalisation and taking part in phase two of the study were significant predictors of parental satisfaction. CONCLUSION: When children were more able to recognise and name hospital staff, this indirectly improved parental satisfaction, even if the number that parents could identify remained unchanged. Displaying staff photographs is a simple way of increasing parental satisfaction during a child's hospitalisation.

BACKGROUND: 3-Methylcrotonyl-CoA carboxylase deficiency (3MCCD) is an inborn error of leucine catabolism. Tandem mass spectrometry newborn screening (NBS) programs worldwide confirmed 3MCCD to be the most common organic aciduria and a relatively benign disorder with favorable outcome. In addition, several asymptomatic 3MCCD mothers were initially identified following abnormal screening of their healthy babies and were appropriately termed maternal 3MCCD. METHODS: This is a retrospective study that summarizes all the clinical, biochemical, and genetic data collected by questionnaires of all 3MCCD individuals that were identified by the extended Israeli NBS program since its introduction in 2009 including maternal 3MCCD cases. RESULTS: A total of 36 3MCCD subjects were diagnosed within the 50-month study period; 16 were classified primary and 20 maternal cases. Four additional 3MCCD individuals were identified following sibling screening. All maternal 3MCCD cases were asymptomatic except for one mother who manifested childhood hypotonia. Most of the primary 3MCCD individuals were asymptomatic except for two whose condition was also complicated by severe prematurity. Initial dried blood spot (DBS) free carnitine was significantly lower in neonates born to 3MCCD mothers compared with newborns with primary 3MCCD (p = 0.0009). Most of the mutations identified in the MCCC1 and MCCC2 genes were missense, five of them were novel. CONCLUSIONS: Maternal 3MCCD is more common than previously thought and its presence may be initially indicated by low DBS free carnitine levels. Our findings provide additional confirmation of the benign nature of 3MCCD and we suggest to exclude this disorder from NBS programs.

BACKGROUND: The unique characteristics of the next generation of medical professionals in Israel and the current model of physician employment in the country may pose a real threat to the high quality of both public clinical care and medical education in the near future, and to the continued flourishing of clinical research. According to the Israel Medical Association's general obligations for Israeli physicians, the doctor should place the patient's interests foremost in his or her mind, before any other issue. This has led many to believe that selflessness or altruism should be among a physician's core values. Is the application and realization of these obligations compatible with the realities of 21st century medicine? Is altruism still a legitimate part of the modern medical world? The Y generation, those born in the 1980s and 1990s, now comprise the majority of the population of residents and young specialists. They have been characterized as ambitious, self-focused, entrepreneurial, lacking loyalty to their employer, and seeking immediate gratification. Under these circumstances, is it possible to encourage or even teach altruism in medical school? Demands on physicians' time are increasing. The shortage of doctors, the growth of the population, the way in which health care is consumed, and the increasing administrative burden have all gnawed away at the time available for individual patient care. This time needs to be protected. The altruism of physicians could become the guarantee of first-rate care in the public sector. The continued existence of clinical research and high level clinical teaching also depends on the allocation of protected time. In light of the emerging generation gap and the expected dominance of Y generation physicians in the medical workforce in the near future, for whom altruism may not be such an obvious value, solutions to these predicaments are discussed.

INTRODUCTION: Lecture attendance by medical students may be affected by various factors. Evidence for compulsory attendance and its effects is scant. AIM: To examine the effect of the introduction of a compulsory attendance regulation on students' grades and behaviour. METHODS: Lecture attendance by students was evaluated and monitored, and the marks gained by attenders and non-attenders compared. The setting was a new medical faculty with a 4-year graduate entry program. The participants were medical students in the 1st year of a 4-year graduate entry program. In the first year, 5 courses were offered in which attendance was not compulsory, followed by 2 courses in which it was made compulsory. RESULTS AND CONCLUSIONS: Attendance rose markedly in the 2 compulsory courses. No clear effect on attainment was seen even among students with high absentee rates. Discussion and summary: In this preliminary study, compulsory attendance improved attendance rates but the range and mean marks of absentee students was similar to the class as a whole. Some students may learn as well or better outside the classroom than in it, although this places an extra burden of responsibility on staff. More research is needed on this important topic.

BACKGROUND: Surgeons have searched for the technique or medication that will produce a 'painless tonsillectomy'; however, this seems to be an impossible goal. Previous studies have shown that perioperative acupuncture may be a useful adjunct for acute postoperative pain and that acupuncture, in addition to nonsteroidal anti-inflammatory drugs, is effective in adults for the treatment of postoperative swallowing pain after tonsillectomy. Acupuncture has been shown to be safe in children. A retrospective review of acupuncture for posttonsillectomy pain in juvenile patients showed a significantly reduced pain score immediately after treatment. AIM: To examine whether acupuncture, in addition to conventional analgesic treatment, will be effective in the treatment of posttonsillectomy pain in children. METHODS: We conducted a randomized, controlled, single-blinded study comparing conventional postoperative analgesic treatment with the same regime plus acupuncture to assess whether postoperative treatment of children aged 3-12 years undergoing tonsillectomy with acupuncture will reduce pain and to examine possible unwanted effects of this treatment. RESULTS: Sixty children were recruited and randomly divided into a study group and a control group. The results indicate that in the study group, there was less pain, less analgesic drug consumption, and higher patient/parent satisfaction with analgesic treatment scores. No adverse effects were recorded. CONCLUSIONS: Acupuncture, in addition to conventional analgesic treatment, is an effective treatment for posttonsillectomy pain. Acupuncture is safe and well received by children and their parents.

BACKGROUND: Unintentional childhood injuries are a leading cause of morbidity and mortality worldwide. Attempts to prevent child home injuries have rarely been implemented in hospital settings which present an important opportunity for intervention. The SHABI ('Keeping our Children Safe; SHomrim Al BetIchut Yeladenu') program recruits at-risk families presenting with child injury to the Emergency Department. Medical/nursing students conduct two home visits and provide safety equipment and guidance. The objective of this study was to investigate the impact of SHABI on participating families' home-safety. METHODS: The pilot was conducted between May 2019 and March 2020 in northern Israel, an area with high child injury rates. Eligibility included families with preschool children who incurred a home injury. Home-safety was assessed by observation through the 'Beterem' checklist. Parents' views, knowledge, awareness of dangers and report of home injuries were assessed at the start of each visit. RESULTS: 352 of 773 eligible families agreed to be contacted. 135 participated, 98 completed both home visits. Significant improvement in home-safety items was observed 4 months after the first visit (14 [IQR12-16]) vs. (17 [IQR15-19]; p < 0.001), accompanied by an overall increase in home safety (Mean ± SD 71.9% ± 9.5% vs. 87.1% ± 8.6%; p < 0.001). 64% reported greater awareness of dangers, 60% affirmed home was safer, and 70% valued the equipment. No difference was found in the prevalence of injuries (14 of 98 families prior and 8 after the visit; p = 0.17). Home visitors reported benefiting from the experience of working with disadvantaged families. CONCLUSION: The program, which included recruitment in a hospital emergency setting and use of healthcare students as home visitors, was successfully implemented and accompanied by significant improvement in home safety with a non-significant trend of child injury decrease.

Hypomyelinating leukodystrophies (HMLs) are disorders involving aberrant myelin formation. The prototype of primary HMLs is the X-linked Pelizaeus-Merzbacher disease (PMD) caused by mutations in PLP1. Recently, homozygous mutations in GJA12 encoding connexin 47 were found in patients with autosomal-recessive Pelizaeus-Merzbacher-like disease (PMLD). However, many patients of both genders with PMLD carry neither PLP1 nor GJA12 mutations. We report a consanguineous Israeli Bedouin kindred with clinical and radiological findings compatible with PMLD, in which linkage to PLP1 and GJA12 was excluded. Using homozygosity mapping and mutation analysis, we have identified a homozygous missense mutation (D29G) not previously described in HSPD1, encoding the mitochondrial heat-shock protein 60 (Hsp60) in all affected individuals. The D29G mutation completely segregates with the disease-associated phenotype. The pathogenic effect of D29G on Hsp60-chaperonin activity was verified by an in vivo E. coli complementation assay, which demonstrated compromised ability of the D29G-Hsp60 mutant protein to support E. coli survival, especially at high temperatures. The disorder, which we have termed MitCHAP-60 disease, can be distinguished from spastic paraplegia 13 (SPG13), another Hsp60-associated autosomal-dominant neurodegenerative disorder, by its autosomal-recessive inheritance pattern, as well as by its early-onset, profound cerebral involvement and lethality. Our findings suggest that Hsp60 defects can cause neurodegenerative pathologies of varying severity, not previously suspected on the basis of the SPG13 phenotype. These findings should help to clarify the important role of Hsp60 in myelinogenesis and neurodegeneration.

The legalization of cannabis for medicinal purposes is becoming increasingly widespread worldwide. The anticipated growing ease of access to cannabis may create an increased risk for passive and/or active ingestion by children. We report a case of a 1.5-year-old infant who presented with unexplained coma that was later proved to be associated with the ingestion of cannabis. This case highlights the importance of considering cannabis ingestion in the differential diagnosis of infantile and toddler coma and the need for public education regarding the risks of childhood exposure in the light of the legalization of cannabis for medical purposes and its greater availability.

BACKGROUND: Human parvovirus B19 is a global and common infectious pathogen in humans, particularly in children. OBJECTIVES: To assess the immunoglobulin G3 seroprevalence of B19 in children in Israel. METHODS: Overall, 128 previously healthy children (1.5-17 years old) hospitalized for various diseases other than acute human parvovirus B19 infection were assessed for IgG to the virus by enzyme-linked immunosorbent assay. RESULTS: The IgG seroprevalence increased from 22% in children aged 1.5-9 years to 52% in older children (P = 0.001). CONCLUSIONS: Our data suggest that most acute parvovirus B19 infections in Israel occur in the early school years, and that by 18 years of age 50% of Israeli children have been infected by the virus.

Prolidase deficiency (PD) is a rare, pan-ethnic, autosomal recessive disease with a broad phenotypic spectrum. Seventeen causative mutations in the PEPD gene have been reported worldwide. The purpose of this study is to characterize, clinically and molecularly, 20 prolidase deficient patients of Arab Moslem and Druze origin from 10 kindreds residing in northern Israel. All PD patients manifested developmental delay and facial dysmorphism. Typical PD dermatological symptoms, splenomegaly, and recurrent respiratory infections presented in varying degrees. Two patients had systemic lupus erythematosus (SLE), and one a novel cystic fibrosis phenotype. Direct DNA sequencing revealed two novel missense mutations, A212P and L368R. In addition, a previously reported S202F mutation was detected in 17 patients from seven Druze and three Arab Moslem kindreds. Patients homozygous for the S202F mutation manifest considerable interfamilial and intrafamilial phenotypic variability. The high prevalence of this mutation among Arab Moslems and Druze residing in northern Israel, and the presence of an identical haplotype along 500,000 bp in patients and their parents, suggests a founder event tracing back to before the breakaway of the Druze from mainstream Moslem society.

AIM: To investigate whether levels of blood HbA1c in diabetic patients are associated with susceptibility of LDL to oxidation. METHODS: LDL was separated from blood of 40 diabetic patients with known blood glucose and HbA1c levels. The tendency to undergo lipid peroxidation was assessed via lag time required for initiation of LDL oxidation. HbA1c formation was measured in vitro following incubation of red blood cell (RBC) hemolysate for 3 months with increasing concentrations of glucose in the absence or presence of LDL or oxidized LDL. RESULTS: Lag time for copper-induced LDL oxidation was twice as long in normal subjects compared to diabetic patients. Correlation analyses between LDL oxidation lag time and HbA1c blood levels revealed an R value of 0.74. Incubation of RBC hemolysate with high glucose concentration (up to 400 mg/dl) resulted in increased blood HbA1c concentration by up to 107%. Addition of LDL to this hemolysate over a period of 3 months resulted in LDL oxidation and an increase in HbA1c levels by up to 168%. Similarly, addition of oxidized LDL to the hemolysate increased HbA1c by up to 240%. CONCLUSIONS: Increased tendency of LDL to undergo lipid peroxidation in diabetic patients contributes to increased levels of blood HbA1c, mainly in those with HbA1c<7.3.

Salbutamol diskus (SD) and formoterol turbuhaler (FT) are both fast-acting beta(2) agonists delivery systems used to relieve bronchoconstriction, such as that which accompanies acute exacerbations of asthma. Although SD (which is used only on an as-needed basis) is flow independent, the FT (currently recommended for regular therapy) requires a forceful deep inspiration. Thus, the efficacy of FT in children with bronchoconstriction may be inferior to that of SD. We have studied the bronchodilatation response induced by FT after a standard adenosine-5-monophosphate (AMP) bronchial challenge, and compared it to that induced by SD, and placebo. Seventeen children (mean age +/- SD 10.3 +/- 1.7 y) with asthma underwent three AMP challenges, each time followed by inhalation of either placebo, SD (200 mug) or FT (9 mug), in random order. Patterns of bronchodilatation (forced expiratory volume in 1 second recovery) to 90% of baseline levels were compared. Both SD and FT were significantly better than placebo. FT was slightly better than SD, but this difference was not statistically significant. FT and SD are both effective bronchodilators and may be of comparable efficiency during acute bronchoconstriction in young children with asthma.

BACKGROUND: The extent and clinical manifestations of acute human parvovirus B19 (B19) infection were assessed in previously healthy hospitalized children admitted with clinical syndromes potentially associated the virus. PATIENTS AND METHODS: The study was prospective and was conducted between October 2002 and August 2004 in the pediatric departments of 3 hospitals in Israel. The survey included previously healthy children who were hospitalized with 1 or more of the following acute diseases: acute nonallergic exanthema, fever for >1 week, aplastic anemia or pancytopenia, acute nonbacterial arthropathy, immune thrombocytopenic purpura (ITP), Henoch-Schönlein purpura (HSP) and aseptic meningitis. A control group of children with a proven, non-B19 infection was also studied. Serum samples obtained from each child on admission were tested for B19 DNA by real-time PCR and B19 IgM by ELISA. Acute B19 infection was defined by the following criteria: positive serum B19-DNA and/or B19 IgM, negative serum B19 IgG, and no other proven infection. RESULTS: Overall, 167 children were included in the study. The mean age was 5.5 +/- 4.6 years (range, 0.5-17), males and females equally divided. Acute B19 infection was demonstrated in 12.6% (n = 21) of the children. Both tests were performed in 19 children and were positive in 10 (53%). In 7 and 2 children, only B19-DNA or B19 IgM, respectively, was positive. Acute B19 infection was documented in 27% (10/39) of children who presented with a variety of acute exanthema diseases; 9% (5/57) of children with acute arthropathy (all 5 had transient synovitis); 10% (2/21) of children with fever >1 week, both presented as mononucleosis syndrome; and in 44% (4/9) of children with transient pancytopenia or aplastic anemia. No acute B19 infection was demonstrated in 15 children with ITP, 9 with HSP, and 6 with aseptic meningitis and among 70 children in the control group. By logistic regression analysis, manifestations significantly associated with acute B19 infection were exanthema (OR 2.9; 95% CI = 1.1-7.5), anemia (OR 6.35; 95% CI = 2.2-18.2) and leucopenia (OR 4.14; 95% CI =1.2-14.2). CONCLUSIONS: Acute B19 infection was documented among 12.6% of children hospitalized with clinical syndrome potentially associated with the virus. Clinical and laboratory features associated with acute B19 infection were exanthema, anemia and leucopenia. Determination of both serum B19-DNA and serum B19 IgM should be performed for the accurate diagnosis of acute B19 infection.
