An unusual case of anisocoria by vegetal intoxication: a case report

Marina Macchiaiolo — 2010-07-20T00:00:00Z

A 12 year old boy presented with an acute onset of anisocoria and blurred vision. Ocular motility was normal but his right pupil was dilated, round but sluggishly reactive to light. There was no history of trauma, eye drops' instillation, nebulised drugs or local ointments. His past medical history was negative.A third nerve palsy was considered but the performed cerebral MRI was normal. On further anamnestic investigation the boy revealed that he had spent the morning doing gardening, and especially working on a "trumpet plant". Datura and Brugmansia are well known toxic plant; all Datura and Brugmasia plants contain, primarily in their seeds and flowers, tropane alkaloids such as scopolamine, hyoscyamine and atropine. Systemic and local intoxications have already been described.The day after anisocoria was much less evident and completely resolved in three days.We present this case of an unusual cause of mydriasis to underline once more the importance of a well and deeply conducted medical hystory.

Emergent factors in Eating Disorders in childhood and preadolescence

Leonardo Sacrato — 2010-07-08T00:00:00Z

We have reviewed the literature related to the current advances in comprehension of Eating Disorders (ED) in childhood and preadolescence. The state of art regarding the psychodynamic models concerning the onset of ED are explained. DSM-IV and ICD-10 criteria are discussed, pointing out their little value in the characterization of early eating difficulties. Historic and new diagnostic classifications are displayed in detail. We provided a clearer description of subclinical patterns. Finally we focus on the key role of the paediatrician in detecting and managing parental concerns regarding feeding.

Economic results of a palivizumab seasonal prophylaxis using a cohorting software and vial sharing.

Elio Coletta — 2010-07-07T00:00:00Z

Background: Respiratory syncytial virus is the most important pathogen in lower respiratory tract infection in infants and young children. In high-risk populations it may develop severe, sometimes fatal, lower respiratory tract infections. A proportion of these infants require admission to intensive care units due to the severity of the condition and the level of care needed. Furthermore, we must consider the possible increased risk of asthma following RSV infection in infancy. Methods: The aim of this work is to show how we strictly coordinated, during the 2008-2009 RSV season, the delivery of prophylaxis while minimising drug cost through vial sharing and cohorting infants with a software performed through Visual Basic programming system. Results: By using this method we have been able to obtain a saving of the 29.2% compared to the theoretical amount. No infant requested hospitalisation for a RSV infection. Conclusions: Such a model ensures all patients to receive appropriate immunization and thus positively influencing the cost-benefit of palivizumab prophylaxis. We hope that our model of care delivery will be of use to other hospitals.

Outcome of children with life-threatening asthma necessitating pediatric intensive care

Kam-Lun Hon — 2010-07-06T00:00:00Z

ObjectiveTo report the outcome of children with life-threatening asthma (LTA) admitted to a university Pediatric Intensive Care Unit (PICU). Methods: Retrospective study between October 2002 and May 2010 was carried out. Every child with LTA and bronchospasm was included. Results: 30 admissions of 28 patients (13 M, 17 F) were identified which accounted for 3% of total PICU admissions (n=1033) over the study period. The majority of patients were toddlers (median age 3.1 years). Few had past history of prematurity, lung diseases, or neuro-developmental conditions. Approximately half had previous admissions for asthma and one-forth with history of non-compliance to recommended treatment for asthma. One patient had parainfluenza virus and one had rhinovirus isolated. None of these factors were associated with need for mechanical ventilation (n=6 admissions). Comparing with patients who did not receive mechanical ventilation, ventilated children had significantly higher PIM2 score (1.65 versus 0.4, p <0.001), higher PCO2 levels (9.3 kPa versus 5.1 kPa, p=0.01) and longer PICU stay (median 2.5 days versus 2 days, p=0.03) The majority of patients received systemic corticosteroids, intravenous or inhaled bronchodilators. There was one pneumothorax but no death in this series. Conclusions: LTA accounted for a small percentage of PICU admissions. Previous hospital admissions for asthma and history of non-compliance were common. Approximately one quarters required ventilatory supports. Regardless of the need for mechanical ventilation, all patients survived with prompt treatment.

The FIMP Medicines for Children Research Network

Ettore Napoleone — 2010-06-30T00:00:00Z

The European Paediatric Regulation (EUPR) calls for the fostering of high quality ethical research and medicinal products to be used in children. The EUPR provides the background, goals, and requirements for paediatric clinical trials. Paediatric clinical trials in children are mandatory to generate data on new drugs as well as on drugs used off-label or for unlicensed indications. The Family Paediatricians Medicines for Children Research Network (FIMP-MCRN) was established in 2003 with the aim of developing competence, infrastructure, networking and education for paediatric clinical trials. The network, consisting of twenty Paediatric Regional Networks has progressed very well and has achieved valuable improvements concerning the conduct of paediatric clinical trials. Furthermore, ad hoc training programs have incremented knowledge about clinical trials in Family Paediatrician Investigators (FPI) and have made medical professionals as well as the public aware of the need and advantages of trials in children.

High prevalence of minor neurologic deficits in a long-term neurodevelopmental follow-up of children with severe persistent pulmonary hypertension of the newborn: a cohort study

Anna Berti — 2010-06-13T00:00:00Z

Background: Persistent pulmonary hypertension of the newborn (PPHN) is a severe condition that determines a profound brain hypoxia. Inhaled nitric oxide was approved for the treatment of PPHN since the end of the 1990s. The debate upon the long term outcome of these children is still open. Our aim was to investigate the incidence of minor long-term neurodevelopmental problems in a cohort of children affected by severe PPHN. Methods: All neonates with severe PPHN treated with inhaled nitric oxide in our facility between 01.01.02 and 31.12.07 were seen in a follow up visit and evaluated with a neurodevelopmental scale, according to their age at the time of observation. Results: in the study period 31 children were diagnosed with severe PPHN. 29 survived. 27 accepted to come for follow-up. Mean age: 41 months (range 12 - 70 months).26% of the evaluated children had some behavioural problems, while 22% had some language disturbances. Conclusions: This is the first neurodevelopmental follow-up of neonates with PPHN in which children older than 36 months have been evaluated.There is an unexpected high incidence of minor neurological deficits, mainly regarding the fields of language and behaviour. These deficits seem to be related to the severity of illness rather than to the treatment. Language and behaviour are considered "higher functions" in humans and their integrity can be better defined in older children.

Factors influencing knowledge about childhood autism among final year undergraduate Medical, Nursing and Psychology students of University of Nigeria, Enugu State, Nigeria

Monday Igwe — 2010-06-13T00:00:00Z

Background: Knowledge and awareness about childhood autism is low among health care workers and the general populace in Nigeria. Poor knowledge about childhood autism among final year medical, nursing and psychology students who would form tomorrow's child health care professionals can compromise early recognition and interventions that are known to improve prognosis in childhood autism. Educational factors that could be influencing knowledge about childhood autism among these future health care professionals are unknown. This study assessed knowledge about childhood autism among final year undergraduate medical, nursing and psychology students in south-eastern Nigeria and determined the factors that could be influencing such knowledge. Methods: One hundred final year undergraduate students were randomly selected from each of the Departments of Medicine, Nursing Science and Psychology respectively of University of Nigeria, Enugu State, Nigeria making a sample size of three hundred. A socio-demographic questionnaire and knowledge about childhood autism among health workers (KCAHW) questionnaire were administered to the students. Results: The total mean score for the three groups of students on the KCAHW questionnaire was 10.67 ± 3.73 out of a possible total score of 19, with medical, nursing and psychology students having total mean scores of 12.24 ± 3.24, 10.76 ± 3.50 and 9.01 ± 3.76 respectively. The mean scores for the three groups showed statistically significant difference for domain 1 (p = 0.000), domain 3 (p = 0.029), domain 4 (p = 0.000) and total score (p = 0.000), with medical students more likely to recognise symptoms and signs of autism compared to nursing and psychology students. The mean score in domain 2 did not show statistically significant difference among the three groups (p = 0.769). The total score on the KCAHW questionnaire is positively correlated with the number of weeks of posting in psychiatry (r = 0.319, p = 0.000) and the number of weeks of posting in paediatrics (r = 0.372, p = 0.000). The total score is also positively correlated with the number of credit hours of lectures in psychiatry/abnormal psychology (r = 0.324, p = 0.000) and the number of credit hours of lectures in paediatrics (r = 0.372, p = 0.000). The field of study also influenced knowledge about childhood autism (p = 0.000). Conclusion: Peculiar situation in this environment as signified by inadequate human resources needed in the area of clinical psychology training often times necessitates employing first degree graduates in psychology into clinical positions. This calls for additional exposure of the undergraduate psychology students to training curriculum aimed at improving their early recognition of symptoms of autism spectrum disorders in this environment.

Chromosome 16p11.2 deletions: another piece in the genetic puzzle of childhood obesity.

Laura Perrone — 2010-06-11T00:00:00Z

Ipercaloric diet and reduced physical activity have driven the rise in the prevalence of childhood obesity over a relatively short time interval. Family and twin studies have led to the conclusion that the strong predicitve value of parental body mass index (BMI) mainly stems from genetic rather than environmental factors. Whereas the common polygenic obesity arises when an individual genetic make-up is susceptible to an environment that promotes energy consumption over energy expenditure, monogenic obesity, on the contrary, is the obesity associated with a single gene mutation, which is sufficient by itself to cause weight gain in a food abundant context. Genes involved in the leptin-melanocortin pathway are often mutated in these cases. The cumulative prevalence of monogenic obesity among children with severe obesity is about 5%.Recently, deletions in the region p11.2 of the chromosome 16 encompassing the gene SH2B1, which is involved in the leptin and insulin signaling, have been reported in about 0.5% of children with severe early-onset obesity. These patients show extreme hyperphagia, severe insulin resistance and, in some cases, mild developmental delay.

Immune disease expressed in liver and platelets in an adolescent: a case report

Henedina Antunes — 2010-06-11T00:00:00Z

We report a case of a 15-year-old boy with autoimmune hepatitis lacking common serologic markers and normal gammaglobulinemia associated with immune thrombocytopenia and family history of psoriasis. He presented to our department with a 4-year history of a cervical posterior lymphadenopathy and recent petechiae. Previous laboratory results 6 months before already showed hepatocellular injury. After exclusion of other causes, the diagnosis of autoimmune hepatitis was made based on clinical grounds, associated immune disorder and histological features of liver biopsy.The authors alert for this atypical presentation of autoimmune hepatitis and associated immune thrombocytopenia.

Focal nodular hyperplasia of the liver: an unusual association with diabetes mellitus in a child and review of literature.

Piero Farruggia — 2010-05-26T00:00:00Z

Hepatic hemangioma, adenoma and focal nodular hyperplasia are the most frequent benign lesions of the liver, but they are all infrequent among pediatric population. The reports of focal nodular hyperplasia in children have recently increased in number, with many cases associated to drug intake, particularly to chemotherapy. We here describe, to our knowledge, the first case of focal nodular hyperplasia in association with diabetes mellitus in childhood.
