Mothers’ postpartum psychological adjustment and infantile colic

Background: Infantile colic is a common problem of early infancy. There is limited data on the relation between postpartum maternal psychological problems and colic. Aim:: To investigate whether infantile colic is associated with postpartum mood disorders or insecure adult attachment style of the mother. Methods: Seventy eight mothers and newborns were enrolled in this prospective, longitudinal study. Maternal depressive symptoms were screened with Edinburgh Postpartum Depression Score (EPDS) and maternal anxiety was assessed with State-Trait Anxiety Inventory (STAI). The Adult Attachment Scale was used to determine the attachment style of the mother. Infantile colic was defined according to Wessel criteria. Results: Infantile colic was present in 17 infants (21.7%); 12.9% of the mothers had an EPDS ⩾13. The mean EPDS of the mothers whose infants had infantile colic (10.2±6.0) was significantly higher than that of the mothers of infants without colic (6.3±4.0). Among infants with infantile colic, 62.5% had mothers who had insecure attachment style, whereas only 31.1% of mothers had insecure attachment when the infant did not have infantile colic. Conclusion: Postpartum maternal depressive symptoms and insecure attachment style are associated with infantile colic. Screening and early intervention of postpartum depression might promote the health of both the mother and infant.

Breastfeeding duration and postpartum psychological adjustment: role of maternal attachment styles.

Aim:u2003 Depressive and anxiety symptoms are common in new mothers. The aim of this study is to explore the link between postpartum psychological adjustment and feeding preferences of the mothers.

Ambulatory blood pressure monitoring in healthy children with parental hypertension.

The aim of this study was to compare ambulatory blood pressure monitoring (ABPM) parameters in offspring with at least one hypertensive parent (HP) to offspring with normotensive parents (NP) and to determine whether gender of parent or child might influence the association between parental hypertension and blood pressure (BP). Eighty-nine healthy children (mean age 11.1u2009±u20093.9xa0years) with HP and 90 controls (mean age 10.5u2009±u20093.1xa0years) with NP were recruited. Age, gender, and height did not differ between the two groups, whereas children of HP had higher weight, body mass index (BMI), and waist circumference compared with healthy controls. No difference was found in casual BP between the two groups. In contrast, during ABPM daytime and nighttime mean systolic and diastolic BP and mean arterial pressure (MAP) standard deviation scores (SDS) were significantly elevated in children with HP. The mean percentage of nocturnal BP decline (dipping) was not significantly different between the two groups. Children with hypertensive mothers had higher daytime systolic and MAP SDS than controls; no such difference was detected for children with hypertensive fathers. Daytime systolic and MAP SDS were significantly elevated in boys with HP compared with boys with NP but failed to be significant in girls. Multiple linear regression analysis showed that parental history of hypertension (Bu2009=u20090.29) and BMI (Bu2009=u20090.03) were independently correlated with increase of daytime MAP SDS. Early changes in ambulatory BP parameters were present in healthy children of HP. BP in HP offspring was influenced by the gender of the affected parent and the offspring.

DNA repair gene XPD and XRCC1 polymorphisms and the risk of febrile neutropenia and mucositis in children with leukemia and lymphoma

The aim of the study is to investigate association between DNA repair gene XPD and XRCC1 polymorphisms and febrile neutropenia (FN) and mucositis. The study population consisted of 29 children with Burkitt lymphoma and 61 children with acute lymphoblastic leukemia. Analysis revealed that XRCC1194Trp allele showed a protective effect against longer FN and mucositis. There was also statistically increased risk for severe mucositis in patients with XRCC1Arg399Gln polymorphism. There are no studies that have examined this relationship before. Further studies with larger cohorts are needed to clarify the association.

Iron deficiency anemia from diagnosis to treatment in children.

Iron deficiency is the most common nutritional deficiency worldwide and an important public health problem especially in developing countries. Since the most important indicator of iron deficieny is anemia, the terms iron deficiency and iron deficiency anemia are often used interchangeably. However, iron deficiency may develop in the absence of anemia and the tissues may be affected from this condition. The most common causes of iron deficiency in children include insufficient intake together with rapid growth, low birth weight and gastrointestinal losses related to excessive intake of cows milk. If insufficient intake can be excluded and there is insufficient response to oral iron treatment in patients with iron deficiency especially in older children, blood loss should be considered as the underlying cause. The main principles in management of iron deficiency anemia include investigation and elimination of the cause leading to iron deficiency, replacement of deficiency, improvement of nutrition and education of the patient and family. In this article, the practical approaches in the diagnosis and treatment of iron deficiency and the experience of our center have been reviewed.

Novel Influenza a (H1N1) Infection in a Pediatric Hematology Oncology Clinic During the 2009–2010 Pandemia

Pandemic influenza A infection (2009 H1N1) was associated with a worldwide outbreak of febrile respiratory infection. Although usually it results in a mild illness, certain patient groups are at increased risk for complications. The authors reviewed their experience in a pediatric hematology-oncology unit to determine the outcome of this disease in children with hematological conditions and solid tumors. During the second outbreak (1 November 2009 to 14 January 2010), a total of 187 children from pediatric clinic were tested for H1N1 influenza A by multiplex polymerase chain reaction (PCR), 63 of them were positive. Patients’ signs and symptoms were recorded prospectively. Ten (35.7%) (5 children with solid tumors, 4 with leukemia, 1 with hereditary spherocytosis) of 28 tested children with hematological conditions were diagnosed with 2009 H1N1 influenza infection. Fever (100%) and cough (90%) were the most common symptoms. Five were neutropenic (neutrophil count <1000/mm3), 4 had severe neutropenia (neutrophil count <500/mm3). Systemic antibiotics were given in 5 patients with the diagnosis of febrile neutropenia. Four were inpatients, others were hospitalized after the diagnosis. One patient required mechanical ventilation; however, he had concomitant invasive fungal infection. Eight patients were treated by oseltamivir, all tolerated the drug well. A total of 4 cases from 9 cancer patients had a delay in their planned chemotherapy for 7 to 15 days. Pandemic H1N1 influenza caused mild symptoms in children with cancer and/or hematological conditions but resulted in delay in anticancer therapy and increase in hospitalization and antibiotic usage.

Urinary tract pathogens and their antimicrobial resistance patterns in Turkish children

Urinary tract infections (UTIs) are among the most common bacterial diseases in childhood affecting approximately 3–5% of girls and 1% of boys [1]. There is growing concern regarding the resistance of urinary pathogens to commonly used antibiotics because of the increasing number of therapeutic failures after empiric treatment [2]. To ensure appropriate treatment, knowledge of the organisms that cause UTI and their antibiotic susceptibility is mandatory [3]. They need to be constantly reevaluated to achieve maximal clinical response before the antibiotic susceptibility of the isolate is known. The aim of this study was to assess the susceptibility of urinary pathogens to commonly used antibiotics in Turkish children with community-acquired UTI. Children who were admitted with the first episode of UTI to the Pediatric Outpatient Clinic and consulted to the Pediatric Nephrology Department between 2001 and 2003 were included in the study prospectively. UTI was defined as the growth of a single pathogen of greater than 100,000 colony-forming units/ml by a properly collected urine specimen in children with febrile disease or urinary symptoms. Transurethral catheterisation was chosen for children who were not toilet trained (387 children, 75.4% of all cases) and clean midstream specimen collection was preferred for toilet trained children. Antimicrobial susceptibility of the isolates was tested by the automatized identification technique called VITEK (bioMerieux, France). Five hundred thirteen uncomplicated community-acquired UTIs were detected in children aged 0–16 years (mean age 3.0 years); 271 (52.8%) of the children were female. The isolated microorganisms were Escherichia coli in 277 (54.0%), Klebsiella spp. in 88 (17.2%), Proteus spp. in 62 (12.1%), Staphylococci spp. in 31 (6.0%), Pseudomonas spp. in 15 (2.9%), Enterococcus spp. in 15 (2.9%), Enterobacter spp. in 13 (2.5%), and others in 12 (2.4%). Gram-positive cocci were isolated in 48 (9.3%) of UTIs. No vancomycin-resistant Enterococcus spp. were isolated. The antibiotic resistance patterns of different gram-negative pathogens are shown in Table 1. A high proportion of the isolates were resistant to ampicillin (69%), amoxicillin/ clavulanate (44%), cefazolin (39%) and trimethoprim– sulfamethoxazole (TMP-SMX) (32%). The most effective drugs against all the isolates were found to be cefepime (99%), cefixime (99%), ceftriaxone (90%), nitrofurantoin (83%) and cefuroxime (79%). There was no antimicrobial resistance to ciprofloxacin and aminoglycosides except in one case. In our study nearly half of the pathogens were resistant to amoxicillin/clavulanate and one-third of them were resistant to TMP-SMX which shows that empiric treatment with TMP-SMX and amoxicillin/clavulanate is inadequate. The results showing 21% resistance to cefuroxime, 17% resistance to nitrofurantoin and 1% resistance to cefixim led us to recommend these drugs for common treatment of UTI in Turkish children. Parenteral treatment options for treatment are second and third generation cephalosporins and aminoglycosides. Our results showed that resistance rates for these drugs are tolerable. Only 10% of the microorganisms displayed resistance to ceftriaxone and none of them showed resistance to aminoglycosides.

A double-blind, crossover, randomized dose-comparison trial of granisetron for the prevention of acute and delayed nausea and emesis in children receiving moderately emetogenic carboplatin-based chemotherapy

BackgroundGranisetron is a safe and effective prophylaxis for nausea and vomiting associated with moderate to highly emetogenic chemotherapy. Few trials have been conducted to determine the optimal effective dose of granisetron in children with cancer. The objective of this report was to compare two doses of granisetron in patients with optic pathway tumors receiving moderately emetogenic doses of carboplatin.Patients and methodsIn this double-blind, crossover, randomized study, antiemetic efficacy and tolerability of two dose levels (10 and 40xa0μg/kg) of granisetron in the prevention of acute and delayed nausea/emesis were compared in children and young adults. A total of 18 patients (13 boys) aged 1–23xa0years (median 7.7xa0years) treated with a moderately emetogenic dose of carboplatin were randomly assigned to receive either 10 or 40xa0μg/kg of slow granisetron intravenous (i.v.) infusions at alternating cycles of chemotherapy in a blinded fashion until the end of the study period or until their chemotherapy regimen ended. In this way, the patients acted as their own controls.ResultsPatients in the granisetron 10 and 40xa0μg/kg groups received 104 and 121 cycles of chemotherapy, respectively. There was no significant difference in antiemetic efficacy in terms of nausea and emesis between the dose groups in the first 5xa0days of chemotherapy. The treatment was well tolerated.ConclusionWe conclude that granisetron 10 and 40xa0μg/kg have comparable efficacy in controlling carboplatin-induced acute and delayed nausea/emesis and is well tolerated in children and young adults.

Acute promyelocytic leukemia treated with idarubicin complicated by focal segmental glomerulosclerosis.

The authors report a 9-year-old boy presenting with a left cerebral ischemic infarction as the first manifestation of acute promyelocytic leukemia. During consolidation chemotherapy, the patient developed nephrotic syndrome and a renal biopsy revealed focal segmental glomerulosclerosis (FSGS). Remission in bone marrow was achieved with chemotherapy, however, new intracranial ischemic areas developed on follow-up. Acute promyelocytic leukemia complicated by FSGS has not been previously reported in children. There may be a relationship between anthracycline treatment and FSGS. Thrombosis could be related with both leukemia and nephrotic syndrome, here thrombosis was the initial symptom, before FSGS was diagnosed.

Membranous nephropathy in Schimke immuno-osseous dysplasia

Schimke immuno-osseous dysplasia is a rare autosomal recessive multi-system disorder, with clinical features of growth retardation, spondylo-epiphyseal dysplasia, nephrotic syndrome and immunodeficiency beginning in childhood. Here, we report a new case, in a 10-year-old boy with characteristic symptoms of Schimke immuno-osseous dysplasia. The patient presented with short stature and, later, developed nephrotic syndrome and peritonitis. In addition, he had perinuclear anti-neutrophilic cytoplasmic antibody (p-ANCA)-positive arthritis. Renal pathology of the patients with this disease usually show focal segmental glomerulonephritis, whereas our patient had membranous nephropathy, which has not previously been reported.
