GRISCELLI SYNDROME: Description of a Case with Rab27A Mutation

A 7-month-old Turkish boy presented with partial albinism and typical clinical features of an accelerated phase, suggesting the diagnosis of Griscelli syndrome. The diagnosis was confirmed by light microscopic evaluation of hair and a peripheral blood smear. Genetic analysis identified a mutation in the Rab27A gene. He was initiated immunosuppressive treatment but accelerated phase could not be ameliorated. He unfortunately died from multiorgan failure. The finding of partial albinism in children should alert clinicians to consider Griscelli syndrome since simple methods can corfirm the diagnosis and early diagnosis is life-saving.

A current analysis of caregivers’ approaches to fever and antipyretic usage

INTRODUCTION The aim of this survey was to investigate the current knowledge, attitudes, and practices of febrile childrens caregivers about fever, antipyretic usage, and temperature measurement methods in a tertiary care hospital. METHODOLOGY A 41-item questionnaire was administered to a convenience sample of febrile childrens caregivers in face-to-face interviews by two research assistants from January 2012 through June 2012 in an urban region of Turkey. RESULTS A total of 1,032 caregivers completed the interview. Approximately one-third of caregivers considered a temperature of less than 37.8°C (100°F) to be a fever, and 13% of all respondents would give antipyretics for a body temperature ≤ 37.8°C. Furthermore, 76% of parents would wake their children from sleep to administer antipyretics. Although a high proportion (89.5%) of respondents believed that fever had harmful effects, 10.5% considered fever to be beneficial. Alternating use of acetaminophen and ibuprofen (44%) and giving antipyretics routinely (71%) before and after immunizations were common parental practices and generally advised by pediatricians. Parents with higher levels of education were more likely to consider fever to be beneficial and to treat fever with antipyretics, and less likely to seek medical attention for mild fever. Most caregivers stated that they were unsure about the right site (90%) and thermometer type (95%) for temperature measurement. CONCLUSIONS Persistent fever anxiety and excessive antipyretic usage may be heightened by the lack of knowledge regarding accurate temperature measurement methods with digital thermometers in our population. Parental education may positively affect the approach to fever and antipyretic usage.

The effects of the estrus cycle and citalopram on anxiety-like behaviors and c-fos expression in rats.

In rats, hormonal fluctuations during the estrus cycle may have numerous behavioral and neurobiological consequences. The aim of this study was to investigate the effects of estrus cycles and citalopram on behavior, ultrasonic vocalizations, anxiety levels, and c-fos expression in rats. With this aim, the rats were grouped into two: (1) a control group (n=16) and (2) a citalopram group (n=16), which received daily intraperitoneal 20mg/kg citalopram from baseline (D0) to the 10th day (D10). Behavioral analysis and ultrasonic vocalization (USV) recordings were made on D0 and D10. Next, the rats were further subgrouped according to estrus phases identified through a vaginal smear (8 proestrus rats and 8 non-proestrus rats, in each group). The rats anxiety levels were analyzed with an elevated plus maze (EPM), and their c-fos expression was measured at the cingulate cortex, the amygdala, and the paraventricular thalamic nucleus. Our results showed that the citalopram group showed significantly more grooming behaviors on D10 than the control group (p=0.002). USVs on D0, D10 and during the EPM did not show any significant differences between the groups. Proestrus rats in the control group showed significantly less anxiety-like behavior during the EPM than the non-proestrus rats in the control group (p=0.028 for time spent in open arms, and p=0.011 for entries into open arms). There was no significant difference in anxiety-like behavior between the control and citalopram groups, and between the proestrus and non-estrous rats in the citalopram group. C-fos expression at the amygdala (p=0.013) and the paraventricular thalamic nucleus (p=0.014) was significantly inhibited in the citalopram group. We concluded that estrus cycles have a significant effect on anxiety levels in rats, which may be suppressed behaviorally and neurobiologically by citalopram.

Drug-induced movement disorders in children at paediatric emergency department: ‘dystonia’

Aim To examine cases with drug-induced dystonic reactions (DIDRs), to identify the complaints of the application, to classify the drugs causing those dystonic reactions (DRs) and to determine the treatment options and protective measures to prevent DIDRs. Method The authors retrospectively analysed 55 cases with DIDRs at paediatric emergency department (PED) in a 5-year period. Results The mean age of the patients was 145.07±56.30 months, and of the 55 cases, 28 cases (50.9%) were boys. Antiemetics and antipsychotics were the most common causes of DIDRs. 35 (70%) patients developed DIDRs at therapeutic doses. Treatment side effect was the most common cause of the DIDRs (78.2%). The most common DIDRs were abnormal postures of the head and neck (56.6%). Laryngospasm was observed only in four cases (7.3%) that used either antipsychotics or psychostimulants. 51 (92.7%) children were treated with parenteral diphenhydramine successfully. Conclusion Dystonia is a common side effect of certain drugs, even when therapeutic doses are administered. Although the most common DIDRs were abnormal postures of the head and neck, rare life-threatening conditions, may develop particularly due to use of antipsychotics. In treatment, diphenhydramine could effectively be used through parenteral way to eliminate the cholinergic effects of those drugs. However, the easiest and the safest way to prevent the development of DRs is to avoid unnecessary drug usage. In conclusion, physicians should be aware that antiemetic and antipsychotic drugs are associated with DRs in normal doses and that those drugs should be prescribed with a correct indication.

Pediatricians manage anaphylaxis poorly regardless of episode severity

No information exists on how the knowledge or the practice of pediatricians regarding anaphylaxis episodes vary with episode severity. The aim of this study was to assess and compare pediatrician knowledge on the management of mild and severe anaphylaxis using clinical scenarios and to determine factors that affect their decisions.

Clinical and epidemiological features of Turkish children with 2009 pandemic influenza A (H1N1) infection: Experience from multiple tertiary paediatric centres in Turkey

Abstract Background: In April 2009 a novel strain of human influenza A, identified as H1N1 virus, rapidly spread worldwide, and in early June 2009 the World Health Organization raised the pandemic alert level to phase 6. Herein we present the largest series of children who were hospitalized due to pandemic H1N1 infection in Turkey. Methods: We conducted a retrospective multicentre analysis of case records involving children hospitalized with influenza-like illness, in whom 2009 H1N1 influenza was diagnosed by reverse-transcriptase polymerase chain reaction assay, at 17 different tertiary hospitals. Results: A total of 821 children with 2009 pandemic H1N1 were hospitalized. The majority of admitted children (56.9%) were younger than 5 y of age. Three hundred and seventy-six children (45.8%) had 1 or more pre-existing conditions. Respiratory complications including wheezing, pneumonia, pneumothorax, pneumomediastinum, and hypoxemia were seen in 272 (33.2%) children. Ninety of the patients (11.0%) were admitted or transferred to the paediatric intensive care units (PICU) and 52 (6.3%) received mechanical ventilation. Thirty-five children (4.3%) died. The mortality rate did not differ between age groups. Of the patients who died, 25.7% were healthy before the H1N1 virus infection. However, the death rate was significantly higher in patients with malignancy, chronic neurological disease, immunosuppressive therapy, at least 1 pre-existing condition, and respiratory complications. The most common causes of mortality were pneumonia and sepsis. Conclusions: In Turkey, 2009 H1N1 infection caused high mortality and PICU admission due to severe respiratory illness and complications, especially in children with an underlying condition.

Cholesterol screening in school children: is family history reliable to choose the ones to screen?

Aim: Hyperlipidemia is a major factor accompanying atherosclerosis. As the basis of atherosclerotic heart disease begins at early childhood, we aim to find out which children should be tested for hypercholesterolemia, what the high cholesterol level in children is and what cautions should be taken to avoid atherosclerosis.

Potential predictors of relapse after treatment of asthma exacerbations in children

BACKGROUND Knowledge of factors that affect relapse will allow close monitoring of patients at risk, resulting in a decreased rate of readmission to the emergency department. OBJECTIVE To determine risk factors associated with relapse within 7 days after treatment of asthma exacerbations in children. METHODS This was a multicenter, prospective study of children with asthma attacks. Patients between the ages of 6 months and 17 years who met the criteria between June 2009 and September 2012 were considered. RESULTS The study included 1177 patients (775 males [65.8%]) with a mean (SD) age of 70.72 (48.24) months. Of them, 199 (16.9%) had a relapse within 1 week after being discharged from the hospital. Factors independently associated with relapse identified by a logistic regression model for the 1,177 study visits were having taken a short-acting inhaled β2-agonist within 6 hours before admission (odds ratio [OR], 2.43; 95% confidence interval [CI], 1.728-3.426; P = .001), presence of retraction on physical examination (OR, 1.76; 95% CI, 1.123-2.774; P = .01), no prescription for high-dose inhaled steroids on release (OR, 2.02; 95% CI, 1.370-3.002; P < .001), and not being given a written instructional plan (OR, 1.55; 95% CI, 1.080-2.226; P = .02). CONCLUSION Whereas having taken short-acting β2-agonists within 6 hours before admission and the presence of retractions on physical examination increased the risk of relapse after treatment of the acute attack, being given high-dose inhaled steroids and a written instructional plan when being sent home reduced the risk.
