Meningococcal ACWYX Conjugate Vaccine in 2-to-29-Year-Olds in Mali and Gambia.

BACKGROUND: An effective, affordable, multivalent meningococcal conjugate vaccine is needed to prevent epidemic meningitis in the African meningitis belt. Data on the safety and immunogenicity of NmCV-5, a pentavalent vaccine targeting the A, C, W, Y, and X serogroups, have been limited. METHODS: We conducted a phase 3, noninferiority trial involving healthy 2-to-29-year-olds in Mali and Gambia. Participants were randomly assigned in a 2:1 ratio to receive a single intramuscular dose of NmCV-5 or the quadrivalent vaccine MenACWY-D. Immunogenicity was assessed at day 28. The noninferiority of NmCV-5 to MenACWY-D was assessed on the basis of the difference in the percentage of participants with a seroresponse (defined as prespecified changes in titer; margin, lower limit of the 96% confidence interval [CI] above -10 percentage points) or geometric mean titer (GMT) ratios (margin, lower limit of the 98.98% CI >0.5). Serogroup X responses in the NmCV-5 group were compared with the lowest response among the MenACWY-D serogroups. Safety was also assessed. RESULTS: A total of 1800 participants received NmCV-5 or MenACWY-D. In the NmCV-5 group, the percentage of participants with a seroresponse ranged from 70.5% (95% CI, 67.8 to 73.2) for serogroup A to 98.5% (95% CI, 97.6 to 99.2) for serogroup W; the percentage with a serogroup X response was 97.2% (95% CI, 96.0 to 98.1). The overall difference between the two vaccines in seroresponse for the four shared serogroups ranged from 1.2 percentage points (96% CI, -0.3 to 3.1) for serogroup W to 20.5 percentage points (96% CI, 15.4 to 25.6) for serogroup A. The overall GMT ratios for the four shared serogroups ranged from 1.7 (98.98% CI, 1.5 to 1.9) for serogroup A to 2.8 (98.98% CI, 2.3 to 3.5) for serogroup C. The serogroup X component of the NmCV-5 vaccine generated seroresponses and GMTs that met the prespecified noninferiority criteria. The incidence of systemic adverse events was similar in the two groups (11.1% in the NmCV-5 group and 9.2% in the MenACWY-D group). CONCLUSIONS: For all four serotypes in common with the MenACWY-D vaccine, the NmCV-5 vaccine elicited immune responses that were noninferior to those elicited by the MenACWY-D vaccine. NmCV-5 also elicited immune responses to serogroup X. No safety concerns were evident.

Tetrahydrobiopterin administration facilitates amphetamine-induced dopamine release and motivation in mice.

Dopamine (DA) is a critical neurotransmitter involved in motivational processes. Tetrahydrobiopterin (BH4) is an essential cofactor for tyrosine hydroxylase, the rate-limiting enzyme in DA synthesis. Decreases in BH4 levels are observed in several DA-related neuropsychiatric diseases involving impairment in motivation. Yet, whether BH4 could be used to treat motivational deficits has not been comprehensively investigated. To investigate the effects of exogenous BH4 administration on the dopaminergic system and related behaviors, we acutely injected mice with BH4 (50 mg/kg). Passage of BH4 through the blood brain barrier and accumulation in brain was measured using the in situ brain perfusion technique. DA release was then recorded using in-vivo micro-dialysis and motivation was evaluated through operant conditioning paradigms in basal condition and after an amphetamine (AMPH) injection. First, we showed that BH4 crosses the blood-brain barrier and that an acute peripheral injection of BH4 is sufficient to increase the concentrations of biopterins in the brain, without affecting BH4- and DA-related protein expression. Second, we report that this increase in BH4 enhanced AMPH-stimulated DA release in the nucleus accumbens. Finally, we found that BH4-induced DA release led to improved performance of a motivational task. Altogether, these findings suggest that BH4, through its action on the dopaminergic tone, could be used as a motivational enhancer.

Cardiac hydatid cyst in the interventricular septum: A literature review.

Human hydatidosis occurs mainly as a result of infection with the larvae of Echinococcus granulosus. Cardiac echinococcosis is an uncommon disease and the interventricular septum is rarely involved. This article is a review of all of the literature related to hydatid cyst in the interventricular septum included in the PubMed database. Forty-five cases reported between 1964 and 2019 were identified.

Changes in the Molecular Epidemiology of Pediatric Bacterial Meningitis in Senegal After Pneumococcal Conjugate Vaccine Introduction.

BACKGROUND: Bacterial meningitis is a major cause of mortality among children under 5 years of age. Senegal is part of World Health Organization-coordinated sentinel site surveillance for pediatric bacterial meningitis surveillance. We conducted this analysis to describe the epidemiology and etiology of bacterial meningitis among children less than 5 years in Senegal from 2010 and to 2016. METHODS: Children who met the inclusion criteria for suspected meningitis at the Centre Hospitalier National d'Enfants Albert Royer, Senegal, from 2010 to 2016 were included. Cerebrospinal fluid specimens were collected from suspected cases examined by routine bacteriology and molecular assays. Serotyping, antimicrobial susceptibility testing, and whole-genome sequencing were performed. RESULTS: A total of 1013 children were admitted with suspected meningitis during the surveillance period. Streptococcus pneumoniae, Neisseria meningitidis, and Haemophilus accounted for 66% (76/115), 25% (29/115), and 9% (10/115) of all confirmed cases, respectively. Most of the suspected cases (63%; 639/1013) and laboratory-confirmed (57%; 66/115) cases occurred during the first year of life. Pneumococcal meningitis case fatality rate was 6-fold higher than that of meningococcal meningitis (28% vs 5%). The predominant pneumococcal lineage causing meningitis was sequence type 618 (n = 7), commonly found among serotype 1 isolates. An ST 2174 lineage that included serotypes 19A and 23F was resistant to trimethoprim-sulfamethoxazole. CONCLUSIONS: There has been a decline in pneumococcal meningitis post-pneumococcal conjugate vaccine introduction in Senegal. However, disease caused by pathogens covered by vaccines in widespread use still persists. There is need for continued effective monitoring of vaccine-preventable meningitis.

Speckle tracking echocardiography in systemic sclerosis: A useful method for detection of myocardial involvement.

BACKGROUND: Systemic sclerosis is a multisystem disorder characterized by tissue fibrosis and organ damage. Heart involvement is one of the main factors shortening survival, which may be underestimated by conventional echocardiography measurements. Two-dimensional speckle-tracking echocardiography is a powerful novel modality to assess subclinical myocardial dysfunction. AIM: The aim of this study is to investigate heart involvement in systemic sclerosis patients, and to determine the usefulness of ventricular longitudinal deformation using the Two-dimensional speckle tracking technology for an early detection of ventricular dysfunction. PATIENTS AND METHODS: Between May 2016 and September 2016, 25 patients with systemic sclerosis and 25 healthy subjects underwent echocardiography to assess heart abnormalities and the strain of the two ventricles using two dimensions' speckle tracking echography. RESULTS: The two groups were comparable in age and gender. Despite comparable left ventricle systolic function (left ventricular ejection fraction patients 64.58±8.87 vs. in healthy 68.2±7.41, P=0.19), patients presented altered longitudinal peak systolic strain values (global longitudinal strain: patients -17.42±1.62 vs. healthy -19.24±8.85, P<0.0001). Despite comparable pulmonary artery systolic pressure, there was a significant alteration in right ventricular systolic and diastolic function assessed by standard measurement. Longitudinal peak systolic strain of the right ventricle was significantly lower in patients compared with controls (P<0.01). CONCLUSION: Ventricular deformation analysis by two dimensions' speckle tracking echocardiography appears to be a sensitive method to detect early ventricular impairment in patients with systemic sclerosis.

Monoamine neurotransmitters and movement disorders in children and adults.

Neurotransmitter disorders comprise a rapidly expanding phenotypically and genetically heterogeneous group. Most of these disorders start in infancy through to childhood, although some forms may arise in adolescence and adulthood, and have various presentations. They may be overlooked if the phenotype leads to misdiagnoses involving various combinations of developmental disorders, hypotonia and movement disorders (dystonia, hyperkinesia, parkinsonism) or other clinical manifestations, such as sleep alterations and mood disorders. Neurotransmitter metabolite levels in cerebrospinal fluid (CSF) may help us to analyze and better understand the metabolic cascade and changes in dopamine and serotonin synthesis, and also guide genetic testing. Indeed, it is important to recognize these disorders in their early stages as they can be greatly improved by drug treatments, and if clinical responses are insufficient, then other agents that may enhance neurotransmission, such as serotonergic drugs and tetrahydrobiopterin (BH4) supplementation, could be considered. Also, a precise genetic diagnosis should be established by gene panels for dystonia, SNP microarrays and whole-exome sequencing. The present brief survey aims to review the present state of the art for the most commonly described and rare disorders of dopamine and serotonin, as well as cofactor deficiencies and dysfunctions, with an overview of clinical features, diagnostic strategies and treatments. Moreover, although these are mainly disorders of infants and children, many may nevertheless reach adulthood; thus, their evolution and treatments should be well known not only by pediatricians, but by neurologists as well, as the latter may be in charge at the stage of diagnosis (rarely) and during the follow-up of these rare patients.

[Results of percutaneous mitral balloon commissurotomy in pregnant women about 12 cases]. / Résultats de la dilatation mitrale percutanée chez la femme enceinte à propos de 12 cas.

INTRODUCTION: Mitral stenosis (MS) is the most common valvular heart disease revealed or exacerbated by pregnancy. Percutaneous mitral balloon commissurotomy (PMC) is currently the treatment of choice when mitral valve morphology is favorable. AIM OF THE STUDY: The purpose of this study is to evaluate the immediate, medium and long term results of percutaneous mitral balloon commissurotomy in pregnant women with a severe symptomatic mitral stenosis despite medical treatment. PATIENTS AND METHODS: It is a retrospective study including 12 pregnant patients diagnosed with severe mitral stenosis and hospitalized in the cardiology department of Habib Thameur hospital between 1994 and 2014. A clinical and ultrasonographic monitoring was performed for over 15 years. RESULTS: Mean patients age was 31.5±4.4 years. All patients were in NYHA class III or IV despite medical treatment. Mitral regurgitation was rated as moderate in four cases. Functional improvement was observed in all cases immediately after the procedure. Mitral valve area increased from 1.02±0.5cm2 averaged to 2±0.35cm2. Mitral regurgitation increased in three cases and appeared in two cases. All patients delivered at term. Newborns were all healthy. Two of them had a low birth weight. On the long term follow-up (95.58±64.1 months), five patients had mitral restenosis: two had a surgical valve replacement and three underwent a second percutaneous mitral balloon commissurotomy. CONCLUSION: The effectiveness of the percutaneous mitral balloon commissurotomy is clearly documented by clinical and echocardiographic evaluation. In the case of pregnancy, the goal is not so much to obtain an optimal result but to cause hemodynamic improvement authorizing the continuation of pregnancy and childbirth.

Impact of rotavirus vaccine on acute gastroenteritis in children under 5 years in Senegal: Experience of sentinel site of the Albert Royer Children's Hospital in Dakar.

BACKGROUND: Acute gastroenteritis (AGE) is a leading cause of morbidity and mortality among children <5 years of age in developing countries, with rotavirus being the most common infectious etiology. In November 2014, monovalent rotavirus vaccine was introduced in Senegal. We determined the impact of rotavirus vaccine on hospitalizations for all-cause and rotavirus related AGE in children <60 months of age. METHODS: We examined two data sources from the national referral hospital. Using sentinel surveillance data from March 2011 to February 2017, we examined the proportion of AGE hospitalizations among children <60 months of age attributable to rotavirus, stratified by age groups (0-11, 12-23 and 24-59 months). Using pediatric logbook data from March 2010 to February 2017, we examined the proportion of all childhood hospitalizations attributable to AGE, among the same age groups. RESULTS: In sentinel surveillance, 673 patients <60 months were hospitalized for AGE, with 30% (203/673) due to rotavirus. In pre-vaccine years, the median proportion of rotavirus-positive hospitalizations was 42%; this proportion declined by 76% to 10% rotavirus positive in 2015-2016 (p < .001) and by 59% to 17% in 2016-2017 (p < .001). From the logbook data, among all children <60 months, a median of 11% of all hospitalizations in the pre-vaccine period were due to AGE, with 2015-2016 seeing a 16% decline (p < .001), to 9% of all hospitalizations, and 2016-2017 seeing a 39% decline (p < .001), to 7% of all hospitalizations. Declines in both rotavirus-associated and all-cause AGE hospitalizations were most marked among infants, with a suggestion of herd effect among older children seen in the surveillance data. CONCLUSION: Rotavirus vaccine demonstrated a significant impact on rotavirus-associated hospitalizations and all-cause AGE hospitalizations in the first two seasons after vaccine introduction in Senegal. Our data support the continued use of this vaccine in national immunization program.

Cost-effectiveness of maternal influenza immunization in Bamako, Mali: A decision analysis.

BACKGROUND: Maternal influenza immunization has gained traction as a strategy to diminish maternal and neonatal mortality. However, efforts to vaccinate pregnant women against influenza in developing countries will require substantial investment. We present cost-effectiveness estimates of maternal influenza immunization based on clinical trial data from Bamako, Mali. METHODS: We parameterized a decision-tree model using prospectively collected trial data on influenza incidence, vaccine efficacy, and direct and indirect influenza-related healthcare expenditures. Since clinical trial participants likely had better access to care than the general Malian population, we also simulated scenarios with poor access to care, including decreased healthcare resource utilization and worse influenza-related outcomes. RESULTS: Under base-case assumptions, a maternal influenza immunization program in Mali would cost $857 (95% UI: $188-$2358) per disability-adjusted life year (DALY) saved. Adjusting for poor access to care yielded a cost-effectiveness ratio of $486 (95% UI: $105-$1425) per DALY saved. Cost-effectiveness ratios were most sensitive to changes in the cost of a maternal vaccination program and to the proportion of laboratory-confirmed influenza among infants warranting hospitalization. Mean cost-effectiveness estimates fell below Mali's GDP per capita when the cost per pregnant woman vaccinated was $1.00 or less with no adjustment for access to care or $1.67 for those with poor access to care. Healthcare expenditures for lab-confirmed influenza were not significantly different than the cost of influenza-like illness. CONCLUSIONS: Maternal influenza immunization in Mali would be cost-effective in most settings if vaccine can be obtained, managed, and administered for ≤$1.00 per pregnant woman.

Methods and insights from the characterization of osteoprogenitor cells of bats (Mammalia: Chiroptera).

Osteoprogenitor cells contribute to the development and maintenance of skeletal tissues. Bats are unique model taxa whose cellular processes are poorly understood, especially in regards to skeletal biology. Forelimb bones of bats, unlike those of terrestrial mammals, bend during flight and function in controlled deformation. As a first step towards understanding the molecular processes governing deposition of this flexible bone matrix, we provide the first method for isolation and differentiation of cell populations derived from the bone marrow and cortical bone of bats, and compare results with those harvested from C57BL/6J mice. Osteogenic capacity of these cells was assessed via absolute quantitative real-time PCR (qPCR) and through quantification of in vitro mineral deposition. Results indicate the differentiated bone cells of bats display significantly lower gene expression of known osteogenic markers (Runt-related transcription factor (RUNX2), osteocalcin (BGLAP) and osterix (SP7)), and deposit a less-mineralized matrix compared with murine controls. By characterizing the in vitro performance of osteoprogenitor cells throughout differentiation and matrix production, this study lays the ground work for in vitro manipulations of bat stem and osteoprogenitor cells and extends our understanding of the cellular diversity across mammals that occupy different habitats.

Advances in the metabolic profiling of acidic compounds in children's urines achieved by comprehensive two-dimensional gas chromatography.

The main objective of this work was to evaluate a comprehensive two-dimensional gas chromatographic (GCxGC) coupled to quadrupole mass spectrometry (qMS) method in the field of biomarker candidates' discovery. To this purpose we developed a GCxGC-qMS method suitable for the separation of organic acids and other classes of compounds with silylable polar hydrogen such as sugars, amino-acids, and vitamins. As compared to those obtained by a widely used 1D-GC method, the urinary chromatographic profiles performed by the proposed 2D-GC method exhibit higher resolution and sensitivity, leading to the detection of up to 92 additional compounds in some urine samples including some well-known biomarkers. In order to validate the proposed method we focused on three metabolites of interest with various functional groups and polarities including CH3-malonic acid (MMA: biomarker of methylmalonic acidemia), 3-hydroxy-3-methyl-glutaric acid (3-OHMGA: biomarker of 3-hydroxy-3-methylglutaric acidemia), and phenylpiruvic acid (PhPA: marker of phenylketonuria). While these three metabolites can be considered as representative of organic acids classically determined by 1D-GC, they cannot be representative of new detected metabolites. Thus, we also focused on quinolic acid (QUIN), taken as an example of biomarker not detected at basal levels with the classical 1D GC-qMS method. In order to obtain sufficient recoveries for all tested compounds, we developed a sample preparation protocol including a step of urea removal followed by two extraction steps using two solvents of different polarity and selectivity. Recoveries with the proposed method reached more than 80% for all targeted compounds and the linearity was satisfactory up to 50µmol/L. The CVs of the within-run and within-laboratory precisions were less than 8% for all tested compounds. The limits of quantification (LOQs) were 0.6µmol/L for MMA, 0.4µmol/L for 3-OHMGA, 0.7µmol/L for PhPA, and 1µmol/L for QUIN. The LOQs of these metabolites obtained by a classical GC-MS method under the same chromatographic conditions were 5µmol/L for MMA, 4µmol/L for 3-OHMGA, 6µmol/L for PhPA while QUIN was below the limit of detection. As compared to 1D-GC, these results highlight the enhanced detectability of urine metabolites by the 2D-GC technique. Our results also show that for each new detected compound it is necessary to develop and validate an appropriate sample preparation procedure.

[A multicenter study on profile of hypertension in focal segmental glomerulosclerosis in Tunisia]. / Profil de l'hypertension artérielle dans la hyalinose segmentaire et focale (HSF). Étude multicentrique de 116 cas en Tunisie.

UNLABELLED: Hypertension in focal segmental glomerulosclerosis is frequent and responsible for the progression of the disease. It could be a circumstance of the diagnosis of FSG or a complication of the nephrotic syndrome. PURPOSE: To determine the prevalence of hypertension among patients with FSG diagnosed in Tunisia and to describe the profile of patients with FSG having hypertension in contrast with who do not. PATIENTS AND METHODS: It was a retrospective multicentric study based on 116 patient files having FSG located in 5 specialized centers in Tunisia. RESULTS: The prevalence of hypertension among our patients was 41%, with a feminine predominance, their mean age was 36.34 ± 15.71 years. The systolic blood pressure among the patients with hypertension was 153.18 mmHg. The nephrotic syndrome was impure due to hypertension in 14.5% of the cases. The patients affected by hypertension were more obese. Proteinuria was higher among those not having hypertension than those with it, who score an average value of 5.67 ± 4.51 g/24h, with an insignificant difference. Serum creatinine at presentation was significantly higher among patients with hypertension. Vascular lesions were present at the renal biopsy among 39.45% of patients affected by hypertension, associated with renal failure in 58.50% of patients. The etiopathogenic treatment of FSG was essentially based on steroids full dose. CONCLUSION: Hypertension is often present in FSG and its' treatment must be as soon as possible in order to slow the progression of kidney chronic disease.

[Systemic sarcoidosis and membranous glomerulonephritis]. / Sarcoïdose systémique et glomérulonéphrite extra-membraneuse.

Renal involvement in sarcoidosis is rare and more often related to calcium metabolism disorders or granulomatous interstitial nephritis. Glomerulonephritis is exceptional. There may be a long latency period between the development of active sarcoidosis and glomerular involvement and inversely. We report a case membranous glomerulonephritis revealing systemic sarcoidosis.

Physical activity, functional ability, and disease activity in children and adolescents with juvenile idiopathic arthritis.

Juvenile idiopathic arthritis (JIA) is a chronic condition known to cause pain-related complications in youth and affect children's physical functioning. There is no data in Arabic children with JIA about the impact of illness upon their physical activity. The objective of this study was to explore physical activity (PA) in children and adolescents with JIA compared with a healthy population and to examine associations between PA, functional ability, and disease activity. Our study included patients with JIA and group control aged between 8 and 17 years. The diagnosis was used according to the International League of Association of Rheumatology (ILAR) criteria 2001. Sociodemographic data and clinical features were collected. Physical activity level and energy expenditure were assessed with a 1-day activity diary and the metabolic equivalent (MET), respectively. Functional ability was assessed with the Moroccan version of the Childhood Health Assessment Questionnaire (CHAQ). Disease activity was measured using the Juvenile Arthritis Disease Activity Score (JADAS). Fifty patients and 50 controls were included (mean ± SD age 11.5 ± 3.3 and 10.5 ± 3.8 years, respectively; p = 0.49) with masculine predominance n = 30 (59.6 %) and n = 29 (58 %), respectively (p = 0.26). The median disease duration was 4.3 years (2-5). The median analog scale (VAS) pain was 20 (10-40). Fourteen patients (28 %) had an active disease. Patient population consisted in majority of oligoarticular arthritis (28 %), 14 patients. The mean of energy expenditure and physical activity were significantly higher in the JIA group. The JIA group spent more time in bed and less time on moderate to vigorous PA than the control group. There is no significant relationship between PA, functional ability, and disease activity. Our study suggests that children and adolescents with JIA have low PA levels and are at risk of losing the benefits of PA. Low PA is not related to functional ability, disease duration, and disease activity in children and adolescent with JIA. A large cohort is necessary to confirm these results.

Novel partial anomalous pulmonary venous connection associated with brain abscess.

BACKGROUND: Right-to-left vascular shunts are associated with brain abscess. CASE REPORT: We present a 47-year-old female with a cryptogenic left thalamic abscess on which Streptococcus mitis grew upon aspiration. Computed tomography of the chest with contrast agent revealed an anomalous connection between the left superior pulmonary and brachiocephalic veins. A right-to-left shunt was confirmed in a transthoracic echocardiogram study in which bubbles were injected into the left arm; this shunt had not previously been noted upon right-arm injection. CONCLUSIONS: We recommend aggressive evaluation for right-to-left shunts in patients who present with cryptogenic brain abscesses. In addition to imaging, this should include a bubble-based study with left-arm saline injection.

Factors influencing the quality of life of Moroccan patients with juvenile idiopathic arthritis.

The aim of our study is to investigate the factors influencing the quality of life, assessed by the Pediatric Quality of Life Inventory 4.0 (PedsQL4) Generic Score Scales, in Moroccan patients with juvenile idiopathic arthritis. This is a cross-sectional study conducted between January and June 2012, covering children with juvenile idiopathic arthritis (JIA) seen at the consultations of El Ayachi Hospital and Children's Hospital of the University Hospital of Rabat. Quality of life is assessed by the PedsQL4 which is a questionnaire composed of 23 items, completed by the child and the parent; the response to each item ranges from 0 to 100, so that higher scores indicate a better quality of life. The functional impact is assessed by the Childhood Health Assessment Questionnaire (CHAQ), and the disease activity by the number of tender and swollen joints, visual analogue scale (VAS) activity, erythrocyte sedimentation rate (ESR), and C-reactive protein. Forty-seven patients are included; the average age of the patients is 11 ± 3.35 years, and 40.4 % are females, with a median disease duration of 4 (2; 6) years. The oligoarticular form presents 26.7 %, the systemic form 24.4 %, and the enthesic form 22.2 %. The median of PedsQL4 is 80.43 (63.19; 92.93), and the median of the CHAQ is 0 (0; 1). Our study shows that some clinical and biological characteristics have significant effects on PedsQL by both parent and child reports. This study suggests that the achievement of the quality of life of our patients with JIA depends on the disease activity measured by swollen joints, the number of awakenings, parent VAS, physician VAS, patient VAS, and the ESR.

Lung abscess: update on microbiology and management.

A lung abscess is a circumscribed collection of pus in the lung as a result of a microbial infection, which leads to cavity formation and often a radiographic finding of an air fluid level. Patients with lung abscesses commonly present to their primary care physician or to the emergency department with "nonresolving pneumonia." Although, the incidence of lung abscess has declined since the introduction of antibiotic treatment, it still carries a mortality of up to 10%-20%. This article discusses in detail the up-to-date microbiology and the management of lung abscesses.

Sleep and its relationship to pain, dysfunction, and disease activity in juvenile idiopathic arthritis.

The objective of this study was to determine the sleep abnormalities that may exist in Moroccan children with juvenile idiopathic arthritis (JIA) and their relationship to pain, dysfunction, and disease activity. Case control study including 47 patients diagnosed with JIA, according to the criteria of the International League of Associations for Rheumatology (ILAR), and 47 healthy children, age and sex matched. Sleep was assessed by Children's Sleep Habits Questionnaire (CSHQ). All parents have filled the 45 items of the CSHQ and grouped into eight subscales: bedtime resistance, sleep onset delay, sleep duration, sleep anxiety, sleep-disordered breathing, night awakenings, parasomnias, and morning awakening/daytime sleepiness. The disease activity was assessed by the number of painful joints, swelling joints, erythrocyte sedimentation rate, c-protein reactive, and Juvenile Arthritis Disease Activity Score (JADAS). Functional assessment was based on the value of Childhood Health Assessment Questionnaire. Pain was assessed by visual analog scale pain. Forty-seven patients were included, with 28 males (59.6 %). Children with JIA had a total score of CSHQ significantly higher than the control cases (p < 0.0001); significant differences were also found in the subscale sleep onset delay, sleep anxiety, sleep-disordered breathing, night awakenings, and parasomnias with a p value of <0.0001, 0.034, <0.0001, 0.001, and 0.00, respectively. Significant association was found between the CSHQ total score and visual analog scale (VAS) physician activity (p = 0.016) and JADAS (p = 0.05). There was a correlation between the sleep-disordered breathing and JADAS (p = 0.04). Sleep onset delay was associated with VAS patient pain (p = 0.05), as nocturnal awakenings and VAS patient pain (p = 0.016). Finally, parasomnias and physician's VAS activity (p = 0.015) and VAS patient pain (p = 0.03) were also correlated. This study suggests that sleep abnormalities are common in children with JIA. Strategies to improve sleep should be studied as a possible tool of improving the quality of life of children with rheumatic disease.

Novel Partial Anomalous Pulmonary Venous Connection Associated with Brain Abscess

BACKGROUND: Right-to-left vascular shunts are associated with brain abscess. CASE REPORT: We present a 47-year-old female with a cryptogenic left thalamic abscess on which Streptococcus mitis grew upon aspiration. Computed tomography of the chest with contrast agent revealed an anomalous connection between the left superior pulmonary and brachiocephalic veins. A right-to-left shunt was confirmed in a transthoracic echocardiogram study in which bubbles were injected into the left arm; this shunt had not previously been noted upon right-arm injection. CONCLUSIONS: We recommend aggressive evaluation for right-to-left shunts in patients who present with cryptogenic brain abscesses. In addition to imaging, this should include a bubble-based study with left-arm saline injection.

The uveitis and its relationship with disease activity and quality of life in Moroccan children with juvenile idiopathic arthritis.

The aim of our study is to investigate ocular involvement in juvenile idiopathic arthritis (JIA) and its relationship with disease activity and quality of life in Moroccan patients who suffer from JIA. This is a cross-sectional study conducted between January and June 2012 which includes patients with juvenile idiopathic arthritis (n = 30). All patients have undergone clinical and paraclinical assessment of JIA and a complete eye examination. Functional impairment is assessed by the Childhood Health Assessment Questionnaire while visual function is studied by the Effect of Youngsters' Eyesight in Quality of Life instrument (EYE-Q). Quality of life is assessed using the Pediatric Quality of Life Inventory Version 4.0 (PedsQL 4.0). Four patients (13.33 %) have uveitis with a confidence interval between 3.4 and 30.7. Involvement is bilateral in three children (75 %). One patient (25 %) has elevated intraocular pressure with loss of the right eye due to glaucoma. There is a strong but not significant relationship between uveitis and the number of awakenings (r = 0.71, p = 0.69) and morning stiffness (r = 3.05, p = 0, 21). This relationship is moderate with erythrocyte sedimentation rate (r = 0.48, p = 0.78) and C-reactive protein (r = 0.25, p = 0.88). A strong but not significant association is found between the overall quality of life assessed by the PedsQL 4.0 and visual function assessed by EYE-Q in the uveitis group (r = -0.64, p = 0.55). This study suggests that uveitis associated with JIA can present serious complications and could have a direct relationship with the activity of the JIA as well as with the quality of life of the patient.
