HHV6-Associated Hydrocephalus in a Pediatric Hematopoietic Stem Cell Transplant Recipient: An Unusual Presentation.

Human herpesvirus 6 (HHV-6) is a widely spread DNA virus that is ubiquitous and persistent with primary infection occurring in early childhood, with reactivation of the infection a common phenomenon in severely immunocompromised hosts, including hematopoietic stem cell transplant (HSCT) patients, influencing morbidity and mortality. A wide spectrum of clinical presentations is reported in the literature with HHV-6 reactivation including post-transplant limbic encephalitis (PALE). We report the unusual case of a 6-year-old female 107 days postallogenic HSCT due to transfusion dependent beta thalassemia major who developed acute cerebellitis with secondary supratentorial hydrocephalus that required invasive surgical intervention. In addition to accompanying imaging findings, the patient tested positive for HHV-6 by PCR from both serum and CSF samples and demonstrated dramatic improvement with the institution of steroid therapy in addition to ganciclovir treatment. The availability of rapid diagnostic measures in addition to a multidisciplinary approach is crucial to manage HHV-6 encephalitis and associated complications in HSCT patients.

Urinary tract infections in children from the Gulf Cooperation Council countries: a literature review (2011-2022).

Urinary tract infections (UTIs) are common healthcare-associated and community-acquired bacterial infections in children. Data on pediatric UTIs in the Gulf Cooperation Council (GCC) region (Bahrain, Kuwait, Oman, Qatar, Saudi Arabia, and the United Arab Emirates) have not been collated. Our aim is to review the published literature on the risk factors, etiology, antimicrobial susceptibility, and treatment of pediatric (aged <18 years) UTIs from healthcare and community settings in the GCC countries.

A Narrative Review of Healthcare-Associated Gram-Negative Infections Among Pediatric Patients in Middle Eastern Countries.

INTRODUCTION: Gram-negative bacteria (GNB) have become prominent across healthcare and community settings due to factors including lack of effective infection control and prevention (ICP) and antimicrobial stewardship programs (ASPs), GNB developing antimicrobial resistance (AMR), and difficulty treating infections. This review summarizes available literature on healthcare-associated infections (HAIs) in Middle Eastern pediatric patients. METHODS: Literature searches were performed with PubMed and Embase databases. Articles not reporting data on GNB, HAIs, pediatric patients, and countries of interest were excluded. RESULTS: The searches resulted in 220 publications, of which 49 met the inclusion criteria and 1 additional study was identified manually. Among 19 studies across Egypt reporting GNB prevalence among pediatric patients, Klebsiella species/K. pneumoniae and Escherichia coli were typically the most common GNB infections; among studies reporting carbapenem resistance and multidrug resistance (MDR), rates reached 86% and 100%, respectively. Similarly, in Saudi Arabia, Klebsiella spp./K. pneumoniae and E. coli were the GNB most consistently associated with infections, and carbapenem resistance (up to 100%) and MDR (up to 75%) were frequently observed. In other Gulf Cooperation Council countries, including Kuwait, Oman, and Qatar, carbapenem resistance and MDR were also commonly reported. In Jordan and Lebanon, E. coli and Klebsiella spp./K. pneumoniae were the most common GNB isolates, and AMR rates reached 100%. DISCUSSION: This review indicated the prevalence of GNB-causing HAIs among pediatric patients in Middle Eastern countries, with studies varying in reporting GNB and AMR. Most publications reported antimicrobial susceptibility of isolated GNB strains, with high prevalence of extended-spectrum beta-lactamase-producing K. pneumoniae and E. coli isolates. A review of ASPs highlighted the lack of data available in the region. CONCLUSIONS: Enhanced implementation of ICP, ASPs, and AMR surveillance is necessary to better understand the widespread burden of antimicrobial-resistant GNB and to better manage GNB-associated HAIs across Middle Eastern countries.

Intravesical gentamicin instillation in the prevention of recurrent urinary tract infections in children with neurogenic bladder- a single-center retrospective observational study.

BACKGROUND: Recurrent urinary tract infections (UTI) in children with neurogenic bladder (NGB) put them at high risk of morbidity and mortality from urosepsis and end-stage renal disease (ESRD). Since the efficacy of low-dose prophylactic antibiotics to prevent these recurrences has been declining since the emergence of extended-spectrum beta-lactamase (ESBL) organisms, intravesical gentamicin instillation has also been used, but only scarce data in children is available in the literature. OBJECTIVE: We evaluate the efficacy of intravesical gentamicin instillation to reduce UTIs in children with NGB, compare it with oral antibiotic prophylaxis and determine its effect on pathogens resistance to antibiotics. STUDY DESIGN: Retrospective observational study of 17 children with NGB managed in a tertiary center. Intravesical gentamicin instillation followed an initial period of oral antibiotic prophylaxis. In a conditional negative binomial regression model, a matched comparison of the rate of UTIs, the identified pathogens and their antibiotics susceptibility between the two therapies was performed for each individual child, RESULTS: When compared to antibiotic prophylaxis, intravesical gentamicin instillation showed no significant difference in the yearly rate of UTI, symptomatic UTI, or admissions for intravenous antibiotic therapy. However, it was associated with a 38% reduction in the incidence rate ratio of UTI (p = 0.04) and 75% of asymptomatic UTI (p = 0.006) After intravesical gentamicin instillation, five children (31%) had a gentamicin-resistant UTI, similar to before that treatment (p = 0.76). DISCUSSION: Although the overall rate of UTI and of asymptomatic infections were significantly lower with intravesical gentamicin instillation than during oral antibiotic therapy, there was no significant difference in the rate of symptomatic UTIs or UTIs requiring admissions, probably because of the small sample size. In addition, neither an emergence of ESBL pathogens nor the rate of pathogens resistance to gentamicin was observed with intravesical gentamicin instillation. As to the potential nephrotoxicity of aminoglycosides, the calculated GFR for all children remained normal. Strengths of our study include the use of a matched paired comparison of each participant with him/herself with each treatment modality, thus eliminating potential confounding by some individual characteristics. In addition, and unlike previous studies, we have also used a robust multivariate statistical analysis to compare counts and rates of outcomes. Limitations include the absence of gentamicin serum levels monitoring, of hearing testing, and also the small sample size. CONCLUSION: Intravesical gentamicin instillation decreases the overall rate of UTI and asymptomatic infections in children with NGB without increasing the rate of bacterial resistance to gentamicin.

Epidemiology of Kawasaki Disease, Its Incomplete Form and Outcomes: A Single-Institution Experience in the United Arab Emirates.

Background and objective Kawasaki disease is a childhood vasculitis, the leading cause of acquired heart disease in children worldwide. Data is lacking in the United Arab Emirates and the Middle East region. We aimed to review the clinical characteristics of patients diagnosed with Kawasaki disease, the response to intravenous immunoglobulin, and the short-term and long-term echocardiographic findings. Study design This is a retrospective cohort study involving patients diagnosed with Kawasaki disease in Tawam Hospital from January 2011 to December 2021. Results A total of 74 patients with a mean age of 36 months were diagnosed with Kawasaki disease, of whom 18 (24%) were below one year of age. Complete Kawasaki disease criteria were fulfilled in 36 patients (49%), while the remaining 38 (51%) were incomplete Kawasaki disease. A positive response to intravenous immunoglobulin occurred in less than 36 hours in 60 patients (84.5%). Echocardiography at the diagnosis of Kawasaki disease was performed on 71 patients, of whom 18 (25.35%) had cardiac involvement. The odds of coronary artery aneurysms in Kawasaki disease were 0.12 at diagnosis. Patients younger than 12 months were significantly more likely to be diagnosed with incomplete Kawasaki disease as compared to older patients (24 vs. 14 patients, P = 0.01). In the multivariate logistic regression analysis, only corticosteroid therapy remained statistically significantly associated with the development of coronary aneurysms (adjusted odds ratio (OR) 13.02, ci 1.05, 161.18; P = 0.045). Conclusion A high proportion of patients with Kawasaki disease had an atypical presentation, especially when under one year of age. There was no association between clinical characteristics or laboratory findings and prompt response to treatment within 36 hours.

A Single-Institution Experience in the Use of Chest Radiographs for Hospitalized Children Labeled as Asthma Exacerbation.

Background: Risks of diagnostic radiation have become more notable lately, particularly in young children with chronic medical conditions. This study reports on the cumulative radiation from chest radiographs in children with asthma. Its main purpose was to review our current practice and suggest minimizing the use of chest radiographs. Methods: The study was retrospective and conducted at a pediatric tertiary center. Eligibility criteria included children 2-15 y, admitted between January 2017 and December 2018 for asthma management. Results: Of the 643 children admitted as "asthma exacerbation," 243 [40% females; age (mean ± SD) 5.4±3.3 y] met the study criteria for inclusion. Ninety-two (38%) children had a temperature of 38.8±0.7°C on the day of admission. Antibiotics were prescribed for 148 (61%) children, mainly for presumed pneumonia. Chest radiographs were requested for 214 (88%) children, mainly on the day of admission. Only 38 (18%) chest radiographs showed focal/multifocal pneumonia justifying antibiotic use. Significant predictors for requesting chest radiographs were antibiotic use for presumed pneumonia, lower oxygen saturation at presentation, and a requested blood culture. The rate of chest radiographs per year was negatively related to the child's age; the younger the child the higher the rate (model coefficient -0.259, P < 0.001). For children < 5 y, the rate of chest radiographs was 1.39 ± 1.21/y and radiation dose 0.028 ± 0.025 mSv/y. The corresponding rates for children ≥5 y were 0.78 ± 0.72/y and 0.008 ± 0.007 mSv/y, respectively (P < 0.001). Conclusion: Chest radiographs were commonly requested for children with asthma, especially younger children. Prospective studies are necessary to measure the impact of this practice on the children's health.

Epidemiological characteristics of children with coronavirus at a joint commission-accredited hospital in the United Arab Emirates.

OBJECTIVES: Our aim was to identify the epidemiological characteristics and transmission patterns of coronavirus (COVID-19) among pediatric patients in the multicultural and multiethnic city of Al Ain in the United Arab Emirates (UAE). METHOD: A retrospective study was conducted by abstracting data from the electronic medical records of pediatric patients with COVID-19 from two major public hospitals in Al Ain. The data of patients from birth through 16 years of the cases with COVID-19 confirmed by reverse transcription-polymerase chain reaction were obtained. In addition to the epidemiological characteristics, transmission patterns, comorbidities, index cases, travel history, and coinfection with other viruses were analyzed. Cohen's kappa was used to assess interrater reliability and descriptive data. Chi-square test was used to assess significant differences between the variables and was conducted using Statistical Product and Service Solutions software. RESULTS: We identified 298 (150 males, 148 females) laboratory-confirmed cases. The patients' median age was 7 years. Of these, 50% had parents who also tested positive. Most patients (86.9%) were healthy without any known medical problems. The coinfection rate was ~2%. CONCLUSION: The epidemiological characteristics of children with COVID-19 in Al Ain are similar to those observed internationally. Children of all ages appeared to be susceptible to COVID-19 and no significant sex or ethnicity differences were detected. Furthermore, this study provides strong evidence of human-to-human transmission.

COVID-19-Related Giant Coronary Aneurysms in an Infant with Multisystem Inflammatory Disorder in Children: The First Case Report from the United Arab Emirates and the Arab Region.

BACKGROUND: Multisystem inflammatory disorder in children and adolescents is a relatively new and rare complication of COVID-19. This complication seems to develop after the infection rather than during the acute phase of COVID-19. The clinical features are similar to a well-known inflammatory syndrome in children, Kawasaki disease, and it can lead to collapse and multiple organ failure requiring intensive care. The COVID-19-associated multisystem inflammatory syndrome in children and adolescents is referred to mutually as pediatric inflammatory multisystem syndrome temporally linked with SARS-CoV-2 (PIMS-TS) or multisystem inflammatory syndrome in children (MIS-C) correlated with COVID-19, and here, it is referred to as MIS-C. Case Presentation. This report describes a nine-month-old Asian infant presented with a two-week history of fever with nonspecific signs of viral illness and erythematous rash. The clinical and biochemical findings were compatible with complicated typical Kawasaki disease (KD). The infant fulfilled the World Health Organization criteria for MIS-C and was treated with intravenous immunoglobulin and anticoagulation, which he responded well to. He was discharged home in good condition after almost 3 weeks of treatment. CONCLUSION: This case highlights a rare but new phenomenon attributed to severe acute respiratory syndrome coronavirus 2 infection. We report the first case report of MIS-C in the United Arab Emirates and Arab region. Among KD's complications, massive aneurysm with thrombosis is rare and usually will have deleterious results if not diagnosed and managed promptly.

Etiology of diarrhea by multiplex polymerase chain reaction among young children in the United Arab Emirates: a case-control study.

BACKGROUND: Little is known about the etiology of childhood diarrhea in the United Arab Emirates (UAE) especially after the introduction of rotavirus vaccines. This study aimed to identify gastrointestinal pathogens in children with diarrhea (cases) and the carriage rate of these pathogens in asymptomatic children (controls). METHODS: Stool samples were collected from 203 cases and 73 controls who presented to two major hospitals in Al Ain city, UAE. Samples were analyzed with Allplex™ Gastrointestinal Full Panel Assay for common entero-pathogens. The association between diarrhea and the isolated pathogens was calculated in a multivariate logistic regression model. The adjusted attributable fractions (aAFs) were calculated for all pathogens significantly associated with cases. RESULTS: At least one pathogen was identified in 87 samples (42.8%) from cases and 17 (23.3%) from controls (P < 0.001). Rotavirus, norovirus GII and adenovirus were significantly more prevalent in cases. Their aAFs with 95% ci are 0.95 (0.64, 1.00) for rotavirus, 0.86 (0.38, 0.97) for norovirus GII and 0.84 (0.29, 0.96) for adenovirus. None of the 13 bacteria tested for were more commonly found in the cases than in controls. Cryptosporidium spp. were more significantly detected in cases than in controls. Co-infections occurred in 27.9% of the children. Viruses and parasites were significantly more likely to occur together only in the cases. CONCLUSIONS: Multiplex PCR revealed high positivity rates in both cases and controls which demand a cautious interpretation. Rotavirus remains the main childhood diarrhea pathogen in UAE. Effective strategies are needed to better control rotavirus and other causative pathogens.

Adverse Events of the BCG (Bacillus Calmette-Guérin) and Rotavirus Vaccines in a Young Infant with Inborn Error of Immunity.

BACKGROUND: The Bacillus Calmette-Guérin (BCG) and rotavirus vaccines are live-attenuated preparations. In the United Arab Emirates, these products are universally administered to the young infants. This unguided practice does not account for the children with immunodeficiency, which frequently manifests after the administration of these vaccines. We present here a young infant with immunodeficiency that developed disseminated tuberculosis infection and severe diarrhea due to these improper immunizations. Case Presentation. This young infant was diagnosed at six months of age with "immunodeficiency type 19" (MIM#615617) due to homozygous nonsense variant, NM_000732.4 (CD3D):c.128G > A, p.Trp43∗ (variation ClinVar#VCV000643120.1; pathogenic). This variant creates premature stop-gain in CD3D (CD3 antigen, delta subunit, autosomal recessive; MIM#186790), resulting in loss-of-function. He also had "X-linked agammaglobulinemia" (MIM#300755) due to hemizygous missense variant, NM_001287344.1 (BTK):c.80G > A, p.Gly27Asp (novel). He had a sibling who passed away in infancy of unknown disease and family members with autoimmune disorders. Despite these clear clues, he was immunized with BCG at birth and rotavirus at 2 and 4 months. He was well in the first four months. He then developed high-fever, lymphadenopathy, and refractory diarrhea. Stool was positive for rotavirus, and lymph node biopsy showed acid-fast bacilli, consistent with tuberculosis lymphadenitis. These infections were serious and markedly complicated his clinical course, which included bone marrow transplantation from a matched sibling. CONCLUSIONS: These unfortunate events could have been avoided by compiling the available clinical information. This patient underscores the importance of implementing proper policies for BCG and rotavirus vaccinations. International registries of adverse events of universally administered vaccines are crucial.

Covid-19 in Children and Young Adolescents in Al Ain, United Arab Emirates- a Retrospective Cross-Sectional Study.

Aim: In this retrospective single-center study, we report our experience with a cohort of children admitted to our hospital in Al Ain City, United Arab Emirates, with confirmed COVID-19. We also compare our findings to similar reports in the literature. Patients and Methods: Between 1st March and 31st May 2020, we reviewed the electronic patient medical records of all children with confirmed COVID-19 (ICD-10 code U07.1) managed in Al Ain hospital, designated as the only COVID-19 center in the city. Results: There were 288 children admitted with a confirmed diagnosis of Covid-19 during the study period (mean age 7.3 years, median 6.5, range 1 month to 16.9 years). The age-specific point prevalence was the highest under the age of 5 years (mean 2.0 per 1,000, 95% ci 1.7, 2.4) and decreased progressively to 0.6 per 1,000 (95% ci 0.4, 0.9) over the age of 14 years. Hospital admission was required for 193 (67%) children while 95 (33%) were discharged from the emergency department. Most children (n = 214, 74%) had been exposed to a family member with suspected or confirmed COVID-19 and asthma which was the most frequent comorbidity (n = 37, 13%). The most common symptoms were cough (n = 130, 45%), fever (n = 14, 4.8%), upper respiratory tract infection (n = 93, 32.3%), and lower respiratory tract infection in 28 (9.7%). None of the children presented with acute respiratory distress syndrome, neurological symptoms, sepsis, or septic shock. Neutropenia (absolute neutrophil count or ANC< 1.5 × 109/L) was observed in 10.4% and thrombocytopenia (<150 platelets × 109/L) in 72% of children. Nineteen patients (9%) had abnormal imaging studies (chest X-ray and chest computed tomography). Abnormalities were bilateral in six (43%), right-sided in seven (50%) with only one child (7%) with left-sided involvement. None of the children required invasive respiratory support, but four (1.4%) required noninvasive respiratory support. The median length of hospital stay was 3.3 days [1.9, 5.9]. There were no deaths in the hospital even in those with comorbidities. Conclusions: Our results confirm previous reports of mild illness of COVID-19 in our child population, even in those with comorbidities. The age-standardized prevalence was higher in children (<5 years) compared to young adolescents.

Severe Presentation of Nontypeable Haemophilus influenzae (NTHi) Infection in a Previously Healthy Toddler.

BACKGROUND: Cellulitis is the inflammation of the skin and subcutaneous tissue. It is usually caused by Gram-positive organisms such as Staphylococcus and Streptococcus pyogenes infection. Nontypeable Haemophilus influenzae (NTHi) is an uncommon cause of cellulitis. Hence, we report on this case. CASE PRESENTATION: A previously healthy 19-month-old girl presented with a fever and two-day history of progressive right leg swelling and redness. Her physical examination revealed significant induration and swelling of her right lower leg but no obvious signs of abscess formation. Given the clinical picture, she was admitted as a case of cellulitis. Parenteral clindamycin was started empirically, as the blood culture preliminary report showed Gram-negative rods. Ceftriaxone was added to broaden the coverage. Final blood culture grew NTHi. Despite the use of proper antibiotics (amoxicillin clavulanic acid), the clinical course was complicated with abscess formation that required surgical intervention. CONCLUSIONS: We are reporting a previously healthy child who developed NTHi cellulitis of the lower leg. To the best of our knowledge, there have been no formal reports pertaining to leg cellulitis following infection by NTHi, yet published in UAE, and reports of HIB cellulitis of the extremities still appear to be rare; hence, we report on this case.

A Rare Case of Lemierre-Like Syndrome: A Case Report and Literature Review.

Lemierre's syndrome (LS) is a serious rare complication of oropharyngeal infections. It is characterized by thrombosis of internal jugular vein that rapidly progresses into sepsis and is typically caused by anaerobes. Most of the reported cases have been linked to Fusobacterium necrophorum; however, there are a handful of reported cases due to aerobes. It is primarily the disease of healthy young adults and can present in school-aged children. The early recognition and treatment of this complication results in resolution of the illness; nevertheless, there have been some concerns about chronic venous insufficiency as a long-term complication. We report a case of a 6-year-old boy, who presented with fever and headache with a history of sore throat. His blood culture was positive for group A Streptococcus (GAS) and was subsequently found to have internal jugular vein, sigmoid, and transverse sinus vein thrombosis.

Disseminated Bacillus Calmette-Guérin (BCG) infections in infants with immunodeficiency.

BACKGROUND: The Bacillus Calmette-Guérin (BCG) preparations are live-attenuated derivatives of Mycobacterium bovis. These products are used to vaccinate infants at birth, a practice that may result in a disseminated infection in those patients who have an unidentified immunodeficiency. CASE PRESENTATION: Patients who were immunized at birth with BCG and who developed a disseminated infection are reported here to emphasize the importance of taking an extensive medical history before giving the BCG vaccine. Patient 1 has a sibling who had familial hemophagocytic lymphohistiocytosis. Patient 2 has a severe immunodeficiency with profound lymphopenia. Patient 3 has a sibling who had a disseminated BCG infection. Patient 4 has two siblings with an immunodeficiency disorder; one sibling passed away in infancy and one is receiving regular immunoglobulin infusions. Patient 5 has profound lymphopenia and his brother had cytomegalovirus (CMV) pneumonitis and passed away in infancy. CONCLUSIONS: These unfortunate events could have been avoided by compiling the relevant clinical and laboratory information. These cases also underscore the importance of a strict adherence to the BCG vaccine policies. Local and international registries that estimate the birth prevalence of primary immune deficiencies are needed prior to implementing universal BCG vaccination administration.

Uric acid excretion in rotavirus gastro-enteritis.

BACKGROUND: Urate urolithiasis in children has been reported in Japan in association with rotavirus (RV) gastro-enteritis (GE). AIMS: To test the hypothesis that children with RV GE have an increased risk of hyperuricosuria compared with GE presumably caused by other viruses. OBJECTIVES: Prospective analytic cohort study of urinary uric acid excretion in children presenting with GE between 1 January 2011 and 31 May 2012. METHODS: Two groups were compared: group R (RV GE) and group N (with presumed other viral causes of GE). Serum urea, creatinine (Scr), uric acid (Sur) and urinary uric acid were compared with creatinine (Uur/Ucr) ratio, fractional excretion of uric acid (FEur) and uric acid for creatinine clearance between the two groups. RESULTS: A total of 87 Emirati children were enrolled in the study. Group R included 46 children (mean age 25 months) and group N 41 children (mean age 43 months). There was no significant difference between the two groups in the blood levels of urea, creatinine, uric acid, nor in urinary pH and specific gravity. Urinary uric acid excretion measured by Uur/Ucr ratio, uric acid for creatinine clearance and FEur was not significantly different between the two groups. CONCLUSION: There was no significant difference in uric acid levels and uric acid excretion between patients with RV GE and those with other presumed viral causes of GE. Further studies with larger sample sizes including children with more severe dehydration and a prolonged course of GE are needed.

Comparison of underlying factors behind parental refusal or consent for lumbar puncture.

BACKGROUND: Although lumbar puncture (LP) is a safe procedure in experienced hands, some parents fear having it performed on their children and refuse consent. The factors associated with this refusal are unclear, and any differences with consenting parents might provide clues as to how to address them. Therefore, we compared the underlying factors between the parents who refuse and those who consent to this procedure, as well as their children's outcomes. METHODS: A prospective study of the two groups of parents was conducted by a face-to-face structured interview. Parents' demographic factors, knowledge, perceptions, beliefs and attitudes, as well as their children's outcomes, were compared. The odds ratio (OR) with 95% confidence intervals was calculated for significant associations. RESULTS: Consent was declined by 24 out of 55 families (44%). Alternative options were offered more often to those refusing consent (OR=5.7). Significantly more parents who refused consent also refused bladder catheterization (OR=18), knowing someone with complications following LP (OR=8.7), felt that it was not needed (OR=7.9) or that it induced complications (OR=12.5). A significantly higher proportion of the consenting parents were aware that meningitis might cause convulsions (OR=4.6), deafness or blindness (OR=2.9). CONCLUSION: The differences in the understanding, perceptions, beliefs and fears between the parents who refused consent and those who agreed, can provide clues to the developing of appropriate strategies when requesting consent for LP.

Why do some parents refuse consent for lumbar puncture on their child? A qualitative study.

OBJECTIVE: Qualitative analysis of the attitudes, beliefs, and perceptions of parents who refuse consent for lumbar puncture (LP) on their child. METHODS: We performed prospective, semistructured, face-to-face interviews with 24 families declining consent for LP in their child (aged between 1 month and 10 years of age), in 2 hospitals, over a 1-year period in the United Arab Emirates. The questionnaire included open-ended questions to allow parents to discuss their beliefs, concerns, and expectations. Content analysis of the transcripts was performed on how parents experienced the issue: their behavior, perceptions, and beliefs, as well as their opinions on what might have made them consent. Identified themes resulting from that analysis were labeled and coded before reducing them into categories and generating a Pareto chart. RESULTS: Seven (29%) families were unfamiliar with LP indications and 3 had the impression that LP was also therapeutic. The emerged themes were fear of complications by 18 (75%), perception that LP was unnecessary by 5 (21%), and distrust of the motives behind the request for consent. Fear of paralysis and conviction that LP is unnecessary encompassed 80% of the causes for refusal. Eleven families (46%) stated that nothing would have made them consent, and 10 (42%) would agree only if the child looked unwell or deteriorated. CONCLUSIONS A better understanding of parents' perceptions, beliefs, and fears will help develop appropriate solutions to their refusal of LP consent.
