Pediatric obesity prevention: From naïve examination of energy imbalance towards strategies that influence the competition for nutrient resources among tissues

Current pediatric obesity interventions have collectively yielded relatively unsuccessful results. In this Field of Vision, we present plausible physiologic underpinnings fostering ineffectiveness of conventional strategies grounded in requisite induction of negative energy imbalance. Moreover, such recommendations exacerbate the underlying metabolic dysfunction by further limiting metabolic fuel availability, lowering energy expenditure, and increasing hunger (recapitulating the starvation response amid apparent nutritional adequacy) which precede and promote obesity during growth and development. The qualitative aspects of musculoskeletal system (i.e., endocrine response, muscle functional capacity) are likely to improve metabolic function and increase nutrient delivery and utilization. An intricate and complex system including multiple feedback mechanisms operates to homeostatically regulate energy balance and support optimal body composition trajectories and metabolic health, during growth and development. Thus, ignoring the interdependencies of regulatory growth processes initiates a nuanced understanding of energy regulation and thus misguided attempts at preventive strategies. Importantly, these gains are not dependent upon weight-loss, rather we suggest can be achieved through resistance training. Collectively, optimizing musculoskeletal health via resistance training elicits augmentation of competitive capacity across systems. Further, substantial gains can be achieved in skeletal muscle mass, strength, and functional capacity through resistance training in a relatively short period of time.

Caffeine therapy in preterm infants

Caffeine is the most commonly used medication for treatment of apnea of prematurity. Its effect has been well established in reducing the frequency of apnea, intermittent hypoxemia, and extubation failure in mechanically ventilated preterm infants. Evidence for additional short-term benefits on reducing the incidence of bronchopulmonary dysplasia and patent ductus arteriosus has also been suggested. Controversies exist among various neonatal intensive care units in terms of drug efficacy compared to other methylxanthines, dosage regimen, time of initiation, duration of therapy, drug safety and value of therapeutic drug monitoring. In the current review, we will summarize the available evidence for the best practice in using caffeine therapy in preterm infants.

Congenital and childhood myotonic dystrophy: Current aspects of disease and future directions

Myotonic dystrophy type 1 (DM1) is multisystem disease arising from mutant CTG expansion in the non-translating region of the dystrophia myotonica protein kinase gene. While DM1 is the most common adult muscular dystrophy, with a worldwide prevalence of one in eight thousand, age of onset varies from before birth to adulthood. There is a broad spectrum of clinical severity, ranging from mild to severe, which correlates with number of DNA repeats. Importantly, the early clinical manifestations and management in congenital and childhood DM1 differ from classic adult DM1. In neonates and children, DM1 predominantly affects muscle strength, cognition, respiratory, central nervous and gastrointestinal systems. Sleep disorders are often under recognised yet a significant morbidity. No effective disease modifying treatment is currently available and neonates and children with DM1 may experience severe physical and intellectual disability, which may be life limiting in the most severe forms. Management is currently supportive, incorporating regular surveillance and treatment of manifestations. Novel therapies, which target the gene and the pathogenic mechanism of abnormal splicing are emerging. Genetic counselling is critical in this autosomal dominant genetic disease with variable penetrance and potential maternal anticipation, as is assisting with family planning and undertaking cascade testing to instigate health surveillance in affected family members. This review incorporates discussion of the clinical manifestations and management of congenital and childhood DM1, with a particular focus on hypersomnolence and sleep disorders. In addition, the molecular genetics, mechanisms of disease pathogenesis and development of novel treatment strategies in DM1 will be summarised.

Use of corticosteroids during acute phase of Kawasaki disease

In spite of initial intravenous immunoglobulin (IVIG) treatment, a significant number of patients are unresponsive to it and are at a higher risk for coronary artery lesions. Corticosteroids have been used as a secondary drug or used in combination with IVIG. Three options of using corticosteroids for the treatment of patients during the acute phase of Kawasaki disease, have been considered. The first is their use exclusively for patients unresponsive to IVIG treatment. The second is their use in combination with IVIG as the routine first line therapy for all patients. The last is the use in the combination as the first line therapy for selected patients at a high risk being unresponsive to initial IVIG. However, it is uncertain that the corticosteroids as the second line treatment are better than the additional IVIG in patients unresponsive to initial IVIG. The combination of corticosteroids and IVIG as the routine first line therapy also have not enough evidences. The last option of using corticosteroids - the combination of corticosteroids and IVIG in patients at high risk of unresponsiveness, is a properly reasonable treatment strategy. However, there have been no globally standardized predictive models for the unresponsiveness to initial IVIG treatment. Therefore, future investigations to determine the best predictive model are necessary.

Inflammatory fibroid polyps in children: A new case report and a systematic review of the pediatric literature

AIM: To study that inflammatory fibroid polyps (IFPs) in children are extremely uncommon tumors that may occur throughout the gastrointestinal tract.

METHODS: A systematic review of the pediatric literature and a report of a new case of IFP is also presented. The PubMed database was searched for original studies on pediatric IFPs since 1960, according to “Preferred reporting items for systematic reviews and meta-analyses” guidelines for systematic reviews.

RESULTS: Five studies were finally enclosed, encompassing 6 children with IFPs (mean age 64 mo). Tumors were located in the stomach (2 patients), in the small bowel (2 patients), in the rectum (1 patient) and in the colon (1 patient). Open surgery was performed in all patients and complete excision of the mass was achieved in all cases. All patients are alive and free of symptom. Authors described a further case of a 3-year-old boy with a large duodenal IFP, in whom the tumor was removed by “en block resection”. The presence of IFP throughout the gastrointestinal tract and its variable clinical appearances make it difficult to diagnose. An accurate pre-operative assessment is fundamental in order to differentiate IFP from other more aggressive gastrointestinal tumor, enabling unnecessary demolitive surgery.

CONCLUSION: When complete resection of the IFP is achieved, the prognosis is excellent.

Coeliac disease in children in Christchurch, New Zealand: Presentation and patterns from 2000-2010

AIM: To evaluate the presentation patterns of a cohort of children diagnosed with coeliac disease (CD) at Christchurch Hospital, New Zealand.

METHODS: Children aged 16 years or less diagnosed with CD at Christchurch Hospital, Christchurch, New Zealand, over the 11 year period between 2000 and 2010 were identified retrospectively. Diagnosis of CD was based upon standard histological criteria of endoscopically-obtained duodenal biopsies. Overlapping search methods were used to identify all relevant diagnoses within the time period. Endoscopy reports and histology findings were reviewed to confirm diagnosis. The numbers of diagnoses per year were calculated and changes in annual rates over the study period were delineated. Available records were reviewed to ascertain presenting symptoms, baseline anthropometry and the indication for referral for each child. In addition, the results of relevant investigations prior to diagnosis were accessed and reviewed. These key investigations included the results of coeliac serology testing (including tissue transglutaminase and endomysial antibodies) as well as the results of tests measuring levels of micronutrients, such as iron. In addition, the histological findings of concurrent biopsies in the oesophagus and stomach were reviewed.

RESULTS: Over the 11 year study period, 263 children were diagnosed with CD at this New Zealand paediatric facility. Children were diagnosed from late infancy to 16.9 years: the largest subgroup of children (n = 111) were diagnosed between 5 and 12 years of age. The numbers of children diagnosed each year increased from 13 per year to 31 per year over the 11 years (P = 0.0095). Preschool children (aged less than 5 years) were more likely to have low weight, and to have diarrhoea and abdominal pain prior to diagnosis. Older children (over 5 years of age) most commonly presented with abdominal pain. Fifty-six (21.6%) of the 263 children were diagnosed following screening in high risk groups, with 38 of these children having no symptoms at diagnosis. Mean weight Z scores were lower in children aged less than five years than children aged 5-12 years or older children (-0.4096 ± 1.24, vs 0.1196 ± 0.966 vs 0.0901 ± 1.14 respectively: P = 0.0033).

CONCLUSION: Increasing numbers of children were diagnosed with CD in this New Zealand centre over this time, with varied presentations and symptoms.

Fever tree revisited: From malaria to autoinflammatory diseases

Over the centuries the idea of recurrent fevers has mainly been associated with malaria, but many other fevers, such as typhoid and diphtheria were cause for concern. It is only in recent times, with the more severe forms of fever from infectious origin becoming less frequent or a cause for worry that we started noticing recurrent fevers without any clear infectious cause, being described as having a pathogenesis of autoinflammatory nature. The use of molecular examinations in many cases can allow a diagnosis where the cause is monogenic. In other cases, however the pathogenesis is likely to be multifactorial and the diagnostic-therapeutic approach is strictly clinical. The old fever tree paradigm developed to describe fevers caused by malaria has been revisited here to describe today’s periodic fevers from the periodic fever adenitis pharyngitis aphthae syndrome to the more rare autoinflammatory diseases. This model may allow us to place cases that are yet to be identified which are likely to be of multifactorial origin.

Efficiency of upper gastrointestinal endoscopy in pediatric surgical practice

After the introduction of flexible fiber optic endoscopy to pediatric gastroenterology in the 1970s, upper gastrointestinal (UGI) endoscopy can be performed for the diagnosis and treatment of all age groups of children. We review indications, contraindications, preparation of patients for the procedure, and details of diagnostic and therapeutic UGI endoscopy used in pediatric surgery. We also discuss potential complications of endoscopy.

Use of laparoscopy as the initial surgical approach of impalpable testes: 10-year experience

AIM: To review the experience in the management of impalpable testes using laparoscopy as the initial approach and the need for inguinal exploration.

METHODS: From January 2004 to June 2014, 339 patients with undescended testes underwent operation in our institute. Fifty patients (15%) had impalpable testes. All children with impalpable testes underwent initial laparoscopy. A retrospective review was conducted on this group of patients and the outcome was analyzed.

RESULTS: Forty children had unilateral impalpable testis. Ten children had bilateral impalpable testes. Thirty-one children (78%) in the unilateral group underwent subsequent inguinal exploration while 4 children (40%) in the bilateral group underwent inguinal exploration (P < 0.05). Orchidopexy was performed in 16 children (40%) in the unilateral group and 9 children (90%) in the bilateral group (P < 0.05). Regarding the 24 children with unilateral impalpable testis and underwent orchidectomy for testicular nubbin (n = 19) or atrophic testes (n = 2) or has vanishing testes (n = 3); contralateral testicular hypertrophy was noticed in 10 (41%). No intra-operative complication was encountered. Two children after staged Fowler-Stephens procedure and 1 child after inguinal orchidopexy had atrophic testes.

CONCLUSION: The use of laparoscopy in children with impalpable testes is a safe procedure and can guide the need for subsequent inguinal exploration. Children with unilateral impalpable testis were associated with an increased need for inguinal exploration after laparoscopy. Orchidopexies could be performed successfully in 90% of children with bilateral impalpable testes.

Single-incision pediatric endosurgery in newborns and infants

This study focuses on the successful application of single-incision pediatric endosurgery in the treatment of congenital anomalies and acquired diseases in neonates and infants. The purpose of this scientific review consists in highlighting the spectrum, indications, applicability, and effectiveness of single-port endosurgery in children during the first 3 postnatal months.

Prevention of neural tube defects with folic acid: The Chinese experience

Neural tube defects (NTDs) are a group of congenital malformations of the central nervous system that are caused by the closure failure of the embryonic neural tube by the 28^th day of conception. Anencephaly and spina bifida are the two major subtypes. Fetuses with anencephaly are often stillborn or electively aborted due to prenatal diagnosis, or they die shortly after birth. Most infants with spina bifida are live-born and, with proper surgical treatment, can survive into adulthood. However, these children often have life-long physical disabilities. China has one of the highest prevalence of NTDs in the world. Inadequate dietary folate intake is believed to be the main cause of the cluster. Unlike many other countries that use staple fortification with folic acid as the public health strategy to prevent NTDs, the Chinese government provides all women who have a rural household registration and who plan to become pregnant with folic acid supplements, free of charge, through a nation-wide program started in 2009. Two to three years after the initiation of the program, the folic acid supplementation rate increased to 85% in the areas of the highest NTD prevalence. The mean plasma folate level of women during early and mid-pregnancy doubled the level before the program was introduced. However, most women began taking folic acid supplements when they knew that they were pregnant. This is too late for the protection of the embryonic neural tube. In a post-program survey of the women who reported folic acid supplementation, less than a quarter of the women began taking supplements prior to pregnancy, indicating that the remaining three quarters of the fetuses remained unprotected during the time of neural tube formation. Therefore, staple food fortification with folic acid should be considered as a priority in the prevention of NTDs.

Response of levetiracetam in neonatal seizures

AIM: To review the clinical response to levetiracetam (LEV) in neonatal seizure management in intensive care unit.

METHODS: Medical records of neonates who received LEV from January 2009 to August 2014 were reviewed. Their demographic data, clinical characteristics, etiology, seizures, electroencephalograms, response to treatment and outcome were noted. Literature review of use of LEV in neonates were also performed via PubMed and EMBASE with keywords - “neonates”, “seizures”, “epilepsy” and “LEV” up to Sep 2014 and retrieved the publications. The response rate to LEV was compared.

RESULTS: Twelve neonates were identified during the study period. All patients received phenobarbitone loading prior to consideration of LEV. Seven (58%) and nine (75%) achieved seizure freedom 24 h and 72 h after LEV was added, both clinically and electrographically. No serious adverse effects were associated with LEV use. From the literature, there are total 144 neonates reported to have used LEV. The overall results suggested that LEV could control up to 90% of neonatal seizures.

CONCLUSION: LEV was found to be relatively safe and efficacious in treating neonatal seizures, but might not work well in the most severe hypoxic ischemic encephalopathy.

Blunted perception of dyspnea in asthmatic children: A potential misleading criterion

Dyspnea (or breathlessness) is a symptom describing a perceived experience of breathing discomfort. Children’s awareness of dyspnea is variable and there is only a poor correlation between the objective respiratory distress measurements and the subjectively awareness of dyspnea. Those who do not perceive dyspnea may not be motivated to comply with their daily prophylactic treatment. Since dyspnea is the main symptom of asthma, and disease management is based largely on the description of symptoms between clinic visits, unreliable symptom report may mislead decision-making for long-term treatment of asthma. Thus, therapeutic decisions should not be taken solely on patients’ perception and description of dyspnea.

Limited brain magnetic resonance imaging for evaluation of non-traumatic pediatric head emergencies

Limited brain magnetic resonance imaging (MRI) consisting of axial fluid attenuated inversion recovery, axial diffusion weighted imaging, coronal single shot fast spin echo (SSFSE) and sagittal SSFSE can be performed in under 5 min of scan time. This approach may provide more information than a non-contrast head computed tomography (CT) in non-traumatic pediatric head emergency, avoid ionizing radiation from CT scan and stratify patients who need more detailed brain MRI. Research studies are required to provide evidence for feasibility of such an approach.

Pyuria in patients with Kawasaki disease

Kawasaki disease (KD) is an acute, febrile vasculitis that predominantly develops in children ≤ 5 years of age and can lead to multiple organ injuries including the kidneys. Of these injuries, pyuria is a common feature of patients with KD, occurring in 30%-80% of patients. Sterile pyuria is most common in KD patients ≤ 1 year of age. KD patients with sterile pyuria exhibit more severe inflammatory reactions and may have sub-clinical renal injuries. Sterile pyuria in KD is associated with mononuclear cells (not neutrophils) in the urine. Although sterile pyuria in KD was at one time thought to be due to urethritis caused by a non-specific vasculitis of the urethra, recent studies suggest that sterile pyuria in KD originates from the urethra, the kidney as a result of mild and sub-clinical renal injuries, and/or the bladder due to cystitis. Pyuria is not always sterile in KD, but can result from a urinary tract infection (UTI). As causative pathogens, Escherichia coli and Klebsiella oxytoca have been reported. The clinical phenotypes do not differ between those with or without UTI. Because some KD patients with UTIs have urinary tract abnormalities such as vesicoureteral reflux, a complete UTI workup including renal ultrasound, voiding cystourethrogram and/or dimercaptosuccinic acid renal scan recommended in KD patients with UTIs.

Clinical asthma phenotyping: A trial for bridging gaps in asthma management

Asthma is a common disease affecting millions of people worldwide and exerting an enormous strain on health resources in many countries. Evidence is increasing that asthma is unlikely to be a single disease but rather a series of complex, overlapping individual diseases or phenotypes, each defined by its unique interaction between genetic and environmental factors. Asthma phenotypes were initially focused on combinations of clinical characteristics, but they are now evolving to link pathophysiological mechanism to subtypes of asthma. Better characterization of those phenotypes is expected to be most useful for allocating asthma therapies. This article reviews different published researches in terms of unbiased approaches to phenotype asthma and emphasizes how the phenotyping exercise is an important step towards proper asthma treatment. It is structured into three sections; the heterogeneity of asthma, the impact of asthma heterogeneity on asthma management and different trials for phenotyping asthma.

Appendicitis in children less than five years old: A challenge for the general practitioner

Acute appendicitis is one of the most common indications for abdominal surgery in pediatrics with peak incidence in the second decade of life. Acute appendicitis in the first years of life is an uncommon event. The clinical presentation is often varied and the diagnosis may be overshadowed by other medical conditions. Gastroenteritis is the most common misdiagnosis, with a history of diarrhea present in 33% to 41% of patients. Pain is the most common presenting symptom in children less than 5 years old, followed by vomiting, fever, anorexia and diarrhea. The most common physical sign is focal tenderness (61% of the patients) followed by guarding (55%), diffuse tenderness (39%), rebound (32%), and mass (6%). Neonatal appendicitis is a very rare disease with high mortality; presenting symptoms are nonspecific with abdominal distension representing the main clinical presentation. The younger the patient, the earlier perforation occurs: 70% of patients less than 3 years develop a perforation within 48 h of onset of symptoms. A timely diagnosis reduces the risk of complications. We highlight the epidemiology, pathophysiology, clinical signs and laboratory clues of appendicitis in young children and suggest an algorithm for early diagnosis.

Endobronchial tumor in children: Unusual finding in recurrent pneumonia, report of three cases

We are reporting 3 cases of pediatric endobronchial tumors presented with recurrent pneumonia. The median age of patients, at time of presentation, was 10.6 years. All patients presented with recurrent pneumonia with a mean time to occurrence, after onset of symptoms, of 14 mo. Bronchoscopy was early performed as part of diagnostic work-up and it revealed an endobronchial mass in every case. Complete surgical resection was performed in all cases, with lung preservation in two of them. Neither post-operative chemotherapy nor radiotherapy was required. The mean duration of follow-up was 7 years and all patients are still alive and disease-free. Recurrent pneumonia, in pediatrics, should raise the suspicion of an obstructing lesion, congenital malformation or systemic disease. A systematic approach is useful for organize the clinicians initial workup. Prompt diagnosis allows parenchymal-sparing surgery, which offers the best chance of cure and reduces clinical and functional complications in these patients.

Spectrum of complicated migraine in children: A common profile in aid to clinical diagnosis

Complicated migraine encompasses several individual clinical syndromes of migraine. Such a syndrome in children frequently presents with various neurological symptoms in the Emergency Department. An acute presentation in the absence of headache presents a diagnostic challenge. A delay in diagnosis and treatment may have medicolegal implication. To date, there are no reports of a common clinical profile proposed in making a clinical diagnosis for the complicated migraine. In this clinical review, we propose and describe: (1) A common clinical profile in aid to clinical diagnosis for spectrum of complicated migraine; (2) How it can be used in differentiating complicated migraine from migraine without aura, migraine with aura, and seizure; (3) We discuss the status of complicated migraine in the International Headache Society classification 2013; and (4) In addition, a common treatment strategy for the spectrum of migraine has been described. To diagnose complicated migraine clinically, it is imperative to adhere with the proposed profile. This will optimize the use of investigation and will also avoid a legal implication of delay in their management. The proposed common clinical profile is incongruent with the International Headache Society 2013. Future classification should minimize the dissociation from clinically encountered syndromes and coin a single word to address collectively this subtype of migraine with an acute presentation of a common clinical profile.

Rituximab for troublesome cases of childhood nephrotic syndrome

Nephrotic syndrome (NS) is the most common glomerular disease of childhood. Steroid-dependent and steroid-resistant nephrotic syndrome present challenges in their pharmaceutical management; patients may need several immunosuppressive medication for optimum control, each of which medication has its own safety profile. Rituximab (RTX) is a monoclonal antibody that targets B cells and has been used successfully for management of lymphoma and rheumatoid arthritis. Recent clinical studies showed that rituximab may be an efficacious and safe alternative for the treatment of complicated nephrotic syndrome. In this review article, we aim to review the efficacy and safety of RTX therapy in nephrotic syndrome. We reviewed the literature pertaining to this topic by searching for relevant studies on PubMed and Medline using specific keywords. The initial search yielded 452 articles. These articles were then examined to ensure their relevance to the topic of research. We focused on multicenter randomized controlled trials with relatively large numbers of patients. A total of 29 articles were finally identified and will be summarized in this review. The majority of clinical studies of RTX in complicated pediatric NS showed that rituximab is effective in approximately 80% of patients with steroid-dependent NS, as it decreases the number of relapses and steroid dosage. However, RTX is less effective at achieving remission in steroid-resistant NS. RTX use was generally safe, and most side effects were transient and infusion-related. More randomized, double-blinded clinical studies are needed to assess the role of RTX in children with nephrotic syndrome.

Neurodevelopmental outcome in congenital diaphragmatic hernia: Evaluation, predictors and outcome

To review the reported neurodevelopmental outcome of congenital diaphragmatic hernia (CDH) survivors, identify important predictors of developmental disabilities, and describe the pathophysiological mechanisms contributing to adverse outcome. A Medline search was performed for English-language articles cross-referencing CDH with pertinent search terms. Retrospective, prospective, and longitudinal follow-up studies were examined. The reference lists of identified articles were also searched. Neurodevelopmental dysfunction has been recognized as one of most common and potentially most disabling outcome of CDH. Intelligence appears to be in the low normal to mildly delayed range. Neuromotor dysfunction is common during early childhood. Behavioral problems, hearing impairment, and quality of life related issues are frequently encountered in older children and adolescence. Disease severity correlates with the degree of neurological dysfunction. Neurodevelopmental follow-up in CDH children should become standard of care to identify those who would benefit from early intervention services and improve neurological outcomes.

Cyclical vomiting syndrome: Recognition, assessment and management

Cyclical vomiting syndrome (CVS) is a functional, debilitating disorder of childhood frequently leading to hospitalization. Affected children usually experience a stereotypical pattern of vomiting though it may vary between different individuals. The vomiting is intense often bilious, and accompanied by disabling nausea. Identifiable precipitating factors for CVS include psychosocial stressors, infections, lack of sleep and occasionally even food triggers. Often, it may be difficult to distinguish episodes of CVS from other causes of acute abdomen and altered consciousness. Thus, the diagnosis of CVS remains largely one of exclusion. Investigations routinely done during the work-up of a child with suspected CVS include both blood and imaging modalities. Plasma lactate, ammonia, amino acid and acylcarnitine profiles as well as urine organic acid profile are indicated to exclude inborn errors of metabolism. The treatment remains challenging and targeted at prevention or shortening of the attacks and can be considered as abortive, supportive and prophylactic. Use of non-pharmacological therapy is also part of the management of CVS. The prognosis of CVS is variable. More insight into the pathogenesis of this disorder as well as role of non-pharmacological therapy is needed.

Recurrent headaches may be caused by cerebral toxoplasmosis

AIM

To establish seroprevalence and provide characteristics of Toxoplasma gondii (TG) infection in children with recurrent headaches.

METHODS

The study was performed in 178 children aged 7-17 years admitted consecutively to the Department of Pediatric Neurology from November 2009 to July 2011. The children were surveyed with a questionnaire with the help and assistance of their parents and blood samples taken on admission were studied for the presence of specific anti-TG IgM, IgG antibodies and IgG avidity using enzyme immunoassay Platelia Toxo IgM, IgG.

RESULTS

The study showed that 19 children (8 boys, 11 girls; 8-17 years old, mean age 14.36 years) had high serum anti-TG IgG antibody levels (range: 32.2 > 240 UI/mL, mean 120.18 UI/mL; positive value for IgG was ≥ 9 UI/mL). The avidity index (AI) ranged from 0.202 to 0.925 (scale: ≥ 0.5 high AI). The results for IgM antibodies were all negative and the obtained results ranged from 0.113 to 0.25 U/mL (mean = 0.191 IU/mL) and all values below 0.8 IU/mL were considered negative. The most frequent complaints found in the seropositive patients were headaches that affected the frontal (13 children), occipital (4) and parietal areas (5). Headaches usually had a pulsating (in 7 patients) and squeezing (6) character and rarely were piercing, dull or expanding. Interestingly, 8 children did not feel discomfort during the headaches, probably because they did not have sufficiently increased intracranial pressure yet. The headaches usually appeared 1-2 times/mo, lasted for 2-6 h, and had a mean intensity of 5.5 points in a 10 point subjective scale. The comorbidities included epilepsy (5 patients), various infections in 3 children (chronic eustachitis, chronic rhinitis, chronic purulent tonsillitis, streptococcal pharyngitis, meningitis, allergic diseases), disturbances of behavior, deficits of attention, and ocular and motor concentration disorders in 1 child. The electroencephalographic and neuroimaging studies performed in our patients had a very limited value in establishing cerebral toxoplasmosis.

CONCLUSION

Ten point six seven percent of the studied children had markedly increased serum anti-TG IgG antibodies and high AI indicated chronic infestation. It is suggested that tests for TG infection should be introduced to routine diagnostics in patients with recurrent headaches.

Preventing medication errors in neonatology: Is it a dream?

Since 1999, the problem of patient safety has drawn particular attention, becoming a priority in health care. A “medication error” (ME) is any preventable event occurring at any phase of the pharmacotherapy process (ordering, transcribing, dispensing, administering, and monitoring) that leads to, or can lead to, harm to the patient. Hence, MEs can involve every professional of the clinical team. MEs range from those with severe consequences to those with little or no impact on the patient. Although a high ME rate has been found in neonatal wards, newborn safety issues have not been adequately studied until now. Healthcare professionals working in neonatal wards are particularly susceptible to committing MEs due to the peculiarities of newborn patients and of the neonatal intensive care unit (NICU) environment. Current neonatal prevention strategies for MEs have been borrowed from adult wards, but many factors such as high costs and organizational barriers have hindered their diffusion. In general, two types of strategies have been proposed: the first strategy consists of identifying human factors that result in errors and redesigning the work in the NICU in order to minimize them; the second one suggests to design and implement effective systems for preventing errors or intercepting them before reaching the patient. In the future, prevention strategies for MEs need to be improved and tailored to the special neonatal population and the NICU environment and, at the same time, every effort will have to be made to support their clinical application.

Transfusion related morbidity in premature babies: Possible mechanisms and implications for practice

Many premature babies, especially those with a low birth weight are given multiple transfusions during their first few weeks of life. The major serious complications of prematurity include bronchopulmonary dysplasia, with lesser incidences of retinopathy of prematurity, intraventricular haemorrhage, and necrotising enterocolitis. Many studies have shown correlations between the receipt of blood transfusions and the development of these conditions, but little is known of the underlying pathophysiology of this relationship. Recent studies are beginning to provide some answers. This review examines recent findings with regard to the influence of preparation and storage of paediatric packed red blood cell units on heme, iron, and oxidative status of the units and relates these to the ability of the premature baby to deal with these changes following the receipt of blood transfusions. Paediatric packed red blood cell units are a potential source of heme, redox active iron and free radicals, and this increases with storage age. Haemolysis of transfused red blood cells may add further iron and cell free haemoglobin to the recipient baby. Premature babies, particularly those with low birth weight and gestational age appear to have little reserve to cope with any additional iron, heme and/or oxidative load. The consequences of these events are discussed with regard to their contribution to the major complications of prematurity and a novel hypothesis regarding transfusion-related morbidity in premature babies is presented. The review concludes with a discussion of potential means of limiting transfusion related iron/heme and oxidative load through the preparation and storage of packed red blood cell units and through modifications in clinical practice.
