Antibiotic associated diarrhea in outpatient pediatric antibiotic therapy

BACKGROUND

Antibiotic-associated diarrhea is one of the most frequent side effects of antimicrobial therapy. We assessed the epidemiological data of antibiotic-associated diarrhea in pediatric patients in our region.

METHODS

The prospective multi-center study included pediatric patients who were initiated an oral antibiotic course in outpatient clinics and followed in a well-established surveillance system. This follow-up system constituded inclusion of patient by the primary physician, supply of family follow-up charts to the family, passing the demographics and clinical information of patient to the Primary Investigator Centre, and a close telephone follow-up of patients for a period of eight weeks by the Primary Investigator Centre.

RESULTS

A result of 758 cases were recruited in the analysis which had a frequency of 10.4% antibiotic-associated diarrhea. Among the cases treated with amoxicillin-clavulanate 10.4%, and cephalosporins 14.4% presented with antibiotic-associated diarrhea. In the analysis of antibiotic-associated diarrhea occurrence according to different geographical regions of Turkey, antibiotic-associated diarrhea episodes differed significantly (p = 0.014), particularly higher in The Eastern Anatolia and Southeastern Anatolia. Though most commonly encountered with cephalosporin use, antibiotic-associated diarrhea is not a frequent side effect.

CONCLUSION

This study on pediatric antibiotic-associated diarrhea displayed epidemiological data and the differences geographically in our region.

Reliability of ultrasonography and the Alvarado scoring system in acute appendicitis

Yazar AS, Erdoğan S, Şahin C, Güven Ş. Reliability of ultrasonography and the Alvarado scoring system in acute appendicitis. Turk J Pediatr 2018; 60: 173-179. In this study, we aimed to evaluate the diagnostic performance of ultrasonography, the Alvarado score, mean platelet volume and C-reactive protein in the diagnosis of acute appendicitis. Patients admitted to the pediatric emergency department with abdominal pain who were operated on with a preliminary diagnosis of acute appendicitis were evaluated. The patients who had acute appendicitis diagnosis in the histopathological assessment were considered as the Appendicitis (App) Group, while patients who did not have acute appendicitis according to histopathology were considered as the Non-app Group. Of 200 patients assessed in the study, 137 (68.5%) were male and 63 (31.5%) were female. Of the patients operated on; 170 (85%) had acute appendicitis, while the pathological results of 30 (15%) were not consistent with acute appendicitis. The Alvarado score of the patients in App Group was significantly higher than those in Non-app Group (p=0.001). The sensitivity and specificity of the Alvarado score and ultrasonography were 60%, 81.18% and respectively, for the diagnosis of appendicitis. There were no significant differences (p > 0.05) in terms of average white blood cell, absolute neutrophil count, platelet count, mean platelet volume and C-reactive protein between the two groups. According to our study the use of Alvarado Scoring System with ultrasonography is more effective and accurative than ultrasonography performing alone. We recommend performing ultrasonography on patients with right lower quadrant pain and suspected appendicitis admitted to the emergency department and to operate on patients with a ultrasonography-supported appendicitis diagnosis and an Alvarado score of 7 and above. Patients with an appendicitis diagnosis not supported by ultrasonography and an Alvarado score lower than 7 should be closely monitored.

Viral etiological causes of febrile seizures for respiratory pathogens (EFES Study)

BACKGROUND

Febrile seizure is the most common childhood neurological disorder, is an important health problem with potential short- and long-term complications, also leading to economic burden and increased parental anxiety about fevers and seizures occurring in their children. There are no routine recommendation to detect etiological causes of FS for neurological perspective, further knowledge about the etiological causes of FS in children will support preventive measures and follow-up strategies. The aim of this study is to evaluate the percentage of respiratory viruses in children with FS.

METHODS

This prospective multicenter study, entitled "Viral etiological causes of febrile seizures for respiratory pathogens (EFES Study)" examined representative populations in eight different cities in Turkey between March 1, 2016 and April 1, 2017. Nasopharyngeal swabs were taken from all children at presentation. A respiratory multiplex array was performed to detect for influenza A and B; respiratory syncytial virus A and B; human parainfluenza virus 1-2-3 and 4; human coronavirus 229E and OC43; human rhinovirus; human enterovirus; human adenovirus; human bocavirus; human metapneumovirus.

RESULTS

During the study period, at least one virus was detected in 82.7% (144/174) of children with FS. The most frequently detected virus was adenovirus, followed by influenza A and influenza B. Detection of more than one virus was present in 58.3% of the children with FS, and the most common co-existence was the presence of adenovirus and influenza B. In children younger than 12 months, Coronavirus OC43 was the most common, while influenza A was most frequently observed in children older than 48 months (p < 0.05). Human bocavirus was common in children who experienced complex FS, while respiratory syncytial virus (RSV) A was more common in children who experienced simple FS. Influenza B virus was the most common virus identified in children who were experiencing their first incidence of FS (p < 0.05).

CONCLUSIONS

This study indicates that respiratory viruses are important in the etiology of FS in children. The results show that antibiotics must be prescribed carefully in children with FS since the majority of cases are related to viral causes. Widespread use of the existing quadrivalent influenza vaccine might be useful for the prevention of FS related to the flu. Further vaccine candidates for potential respiratory pathogens, including RSV, might be helpful for the prevention of FS.

Drug Reaction with Eosinophilia and Systemic Symptoms (DRESS) syndrome associated with cefotaxime and clindamycin use in a 6 year-old boy: a case report

Drug reaction with eosinophilia and systemic symptoms (DRESS) syndrome is a rare and potentially life-threatening idiosyncratic drug reaction. It presents with extensive rash, fever, lymphadenopathy, hematologic abnormalities (eosinophilia and/or atypical lymphocytosis) and internal organ involvement. It has been described in association with more than 50 drugs. To the best of our knowledge neither cefotaxime nor clindamycin has been previously reported to induce DRESS syndrome in children. Clindamycin was reported only in adults as a cause of DRESS syndrome in the literature. In this report, we aimed to present a child with DRESS syndrome that developed after cefotaxime and clindamycin treatment. A 6-year-old boy was diagnosed with the left lower lobe pneumonia and pleural effusion. Parenteral cefotaxime and clindamycin were then started, after which the patient improved clinically and was discharged 7 days later with oral amoxicillin clavulanate treatment. After four days he was readmitted to the hospital with fever and cough. Chest X-ray revealed left lower lobe pneumonia and pleural effusion. We considered that the pneumonia was unresponsive to oral antibiotic treatment, and therefore parenteral cefotaxime and clindamycin were re-administered. As a result, his clinical and radiological findings were improved within 10 days. On the 12^th of day of hospitalization, the body temperature has risen to 39°C, which we considered to be caused by antibiotics and stopped antibiotic treatment. At the same day he developed generalized maculopapular erythematous rash, which was considered an allergic reaction secondary to antibiotics. Despite the antihistaminic drug administration, the clinical status quickly deteriorated with generalized edema, lymphadenopathies and hepatosplenomegaly. Laboratory tests revealed a white blood cell count of 4300/μl, a lymphocyte count of 1300/μl, a hemoglobin level of 11.2 gr/dl, a platelet count of 120.000/μl, an eosinophilia ratio of 10% on peripheral blood smear, a C-reactive protein level of 20 mg/dl, a procalcitonin level of 23.94 ng/ml and an erythrocyte sedimentation rate of 48 mm/h. Anti nuclear antibody, anti-double stranded DNA, the serologic tests for Epstein Bar virus, herpes simplex virus, parvovirus, mycoplasma, toxoplasmosis, rubella, cytomegalovirus were all found negative. Bone marrow aspiration was consistent with an autoimmune reaction. An echocardiographic examination was normal. Thoracic tomography revealed multiple enlarged axillary, supraclavicular and anterior mediastinal lymph nodes. As the patient met 8 out of 9 RegiSCAR criteria for the diagnosis of DRESS, we started pulse methyl prednisolone (30 mg/kg/day) for three days followed by 2 mg/kg/day. On the 2nd day fever resolved and cutaneous rash and edema improved. Ten days after developing eruptions the patient was discharged. To our knowledge, we report the first pediatric case of DRESS syndrome following treatment with cefotaxime and clindamycin. Pediatricians should be aware of this potential complication associated with these commonly prescribed antibiotics.

Effectiveness of a sleep education program for pediatricians

BACKGROUND

The high prevalence of sleep problems in children and long-term consequences point to the need for early effective interventions, but health-care providers have limited training in pediatric sleep medicine. The aims of this study were therefore to assess the effectiveness of a sleep health-care education program and to develop a Turkish acronym for brief sleep history taking for pediatric primary caregivers in the ambulatory setting.

METHODS

This was a quasi-experimental study. Four centers were randomly selected from eight training and research hospitals as the intervention group. The control group was recruited during training in subjects other than sleep. Education was provided to the intervention group. Knowledge and attitudes were evaluated in the short and long term.

RESULTS

The intervention and the control groups consisted of 132 and 78 pediatricians, respectively. The intervention group scored significantly higher both in the short and the long term. The Turkish acronym (UYKU) was reported to be easy to remember and effective in prompting the correct questions to ask about sleep issues.

CONCLUSIONS

The Turkish acronym would be useful in the primary care setting to increase the frequency of screening of sleep problems in children. Although education significantly improved knowledge on sleep issues in children, the percentage of participants who lacked confidence in the management of sleep problems in children was still very high, even in the intervention group. We suggest that a broader educational program, carried out more than once, would be more beneficial.

Lactobacillus reuteri DSM 17938 shortens acute infectious diarrhea in a pediatric outpatient setting

OBJECTIVE

Two randomized controlled clinical trials have shown that Lactobacillus (L) reuteri DSM 17938 reduces the duration of diarrhea in children hospitalized due to acute infectious diarrhea. This was the first trial evaluating the efficacy of L. reuteri DSM 17938 in outpatient children with acute infectious diarrhea.

METHODS

This was a multicenter, randomized, single-blinded, case control clinical trial in children with acute watery diarrhea. A total of 64 children who presented at outpatient clinics were enrolled. The probiotic group received 1×10(8)CFU L. reuteri DSM 17938 for five days in addition to oral rehydration solution (ORS) and the second group was treated with ORS only. The primary endpoint was the duration of diarrhea (in hours). The secondary endpoint was the number of children with diarrhea at each day of the five days of intervention. Adverse events were also recorded.

RESULTS

The mean duration of diarrhea was significantly reduced in the L. reuteri group compared to the control group (approximately 15h, 60.4±24.5h [95% CI: 51.0-69.7h] vs. 74.3±15.3h [95% CI: 68.7-79.9h], p<0.05). The percentage of children with diarrhea was lower in the L. reuteri group (13/29; 44.8%) after 48h than the control group (27/31; 87%; RR: 0.51; 95% CI: 0.34-0.79, p<0.01). From the 72nd hour of intervention onwards, there was no difference between the two groups in the percentage of children with diarrhea. No adverse effects related to L. reuteri were noted.

CONCLUSION

L. reuteri DSM 17938 is effective, safe, and well-tolerated in outpatient children with acute infectious diarrhea.

Early neonatal outcomes of volume guaranteed ventilation in preterm infants with respiratory distress syndrome

BACKGROUND

Volume guaranteed (VG) synchronized intermittent mandatory ventilation (SIMV) is a novel mode of SIMV that provides automatic adjustment of the peak inspiratory pressure for ensuring a minimum set tidal volume and there are limited data about the effects of VG ventilation on short term neonatal outcomes in preterm infants with respiratory distress syndrome (RDS).

OBJECTIVE

The main objective of this study was to evaluate the effect of VG ventilation on duration of ventilation and total supplemental oxygen. We also aimed to compare the early neonatal outcomes of VG ventilation versus conventional SIMV on short-term outcomes in preterm babies with RDS who were given surfactant.

METHODS

In this randomized controlled study, preterm infants who were admitted with RDS and given surfactant were divided into 2 groups: group 1 included infants ventilated on conventional SIMV (n = 30) and group 2 included infants ventilated on VG ventilation (n = 42). Neonatal morbidities such as air leak, bronchopulmonary dysplasia (BPD), intraventricular hemorrhage (IVH), retinopathy of prematurity (ROP), necrotizing enterocolitis (NEC) and duration of mechanical ventilation and total oxygen supplementation were all recorded.

RESULTS

There were no significant differences between two groups in terms of demographic features. Infants ventilated with VG mode had significantly shorter duration of ventilation and need of total supplemental oxygen. The incidences of oxygen related short term complications including BPD, ROP, and IVH were also significantly lower in these infants compared with those ventilated with conventional SIMV. No significant differences were found between two groups with respect to NEC and air leak.

CONCLUSION

In conclusion, VG ventilation in combination with surfactant treatment significantly reduced both duration of mechanical ventilation and early neonatal oxygen related morbidities including BPD, ROP and IVH in preterm infants with RDS. This data favors the use of VG ventilation in respiratory support of premature infants.

Congenital central hypoventilation syndrome with hirschsprung's disease due to PHOX2B gene mutation in a Turkish infant

The association of congenital central hypoventilation syndrome (also known as Ondine's curse) and Hirschsprung's disease is termed Haddad syndrome, which is an extremely rare disorder. Recent studies have described that the PHOX2B gene mutation was responsible for congenital central hypoventilation syndrome. We report a term newborn male infant with clinical manifestations of recurrent hypoventilation with hypercapnia and bowel obstructions. These clinical manifestations were compatible with congenital central hypoventilation syndrome and Hirschsprung's disease. PHOXB direct sequencing showed a heterozygous in-frame duplication of 21 bp leading to an expansion of +7 alanines within the 20 alanine stretch of the PHOX2B gene and confirmed our diagnosis. In addition to a high index of clinical suspicion, testing for PHOX2B mutation can assist iq the diagnosis of congenital central hypoventilation syndrome and in the prediction of disease progression. Infants presenting with congenital central hypoventilation syndrome should also be screened for Hirschsprung's disease.
