Cost-effectiveness of rotavirus vaccination in Turkey.

BACKGROUND/PURPOSE: Cost-effectiveness studies about rotavirus (RV) vaccination programs were performed in many countries due to the severe economic burden of RV infections. This study is an economic evaluation performed to assess the potential for introducing the RV vaccine to the Turkish National Immunization Program. METHODS: In this retrospective clinical study, the records and laboratory findings of a total of 4126 patients admitted to Turgut Ozal University Hospital, Ankara, Turkey with acute gastroenteritis were analyzed. A model described by Parashar et al. was used to obtain the annual episodes of diarrhea, hospitalization and outpatients visits in Turkey. Monovalent and pentavalent vaccination was assumed to protect in average 85% of RV acute gastroenteritis. All costs are expressed in 2012 United States (US) $, where US$1 equals 1.8 Turkish Liras (TL). Losses of labor costs were not taken into consideration. RESULTS: The vaccination program with 85% coverage was cost effective and cost saving compared to no vaccination. A projected birth cohort of 1.25 million children was followed until 5 years of age; a routine vaccination could potentially avert 210,994 cases of diarrhea treated in outpatient hospital facilities and 42,715 hospitalizations. The RV associated economic burden was obtained as US$17,909 million per year (US$14.33 per birth annually) in medical direct costs by using the national level of RV diarrhea disease burden estimates. For monovalent and pentavalent vaccination, assuming a cost of US$31.5 and US$38 per vaccine course, the cost of the vaccination program was estimated to be approximately US$37,878 million and US$45,475 million, respectively. CONCLUSION: At a cost per vaccine course of US$31.5 for monovalent and US$38 for pentavalent vaccine, routine RV vaccination could be potentially cost effective and also cost saving in Turkey. National RV vaccinations will play a significant role in preventing RV infections.

The Addition of Inhaled Budesonide to Standard Therapy Shortens the Length of Stay in Hospital for Asthmatic Preschool Children: A Randomized, Double-Blind, Placebo-Controlled Trial.

BACKGROUND: Asthma exacerbations lead to frequent emergency visits and hospitalizations, and are associated with high morbidity and occasionally mortality. New therapeutic strategies are needed. We sought to investigate whether the addition of high-dose inhaled budesonide to standard therapy would shorten the length of stay (LOS) in hospital of children admitted for asthma exacerbations. METHODS: The study was designed as a single-center, double-blind, placebo-controlled and parallel-group trial. Children aged 7-72 months and admitted with an asthma exacerbation clinical asthma score (CAS) of between 3 and 9 were allocated to either the budesonide (n = 50) or the placebo (n = 50) group. Hospital LOS was compared between children who received 2 mg/day of budesonide versus placebo in addition to standard management of asthma exacerbation involving oxygen inhalation and ß2-agonist, anticholinergic and oral corticosteroid therapy. All patients were assessed every 4 h. Children with a CAS <3, a peripheral oxygen saturation >95% and normal pulmonary function, and those with a symptom-free period of at least 4 h after salbutamol treatment were discharged. RESULTS: Total hospital LOS was significantly shorter in the budesonide group than in the placebo group (median: 44 vs. 80 h, respectively; p = 0.01). When compared with placebo, the number of inpatients was significantly less in the budesonide group at all the assessed end points (Kaplan-Meier; p = 0.022). Additionally, nebulized budesonide was found to reduce the overall cost of treatment. CONCLUSION: We demonstrated that, for children hospitalized for asthma exacerbations, an additional 2 mg/day of nebulized budesonide significantly reduced hospital LOS as well as the overall cost of treatment.

Probiotics and infantile atopic eczema.

Pediatric eczema is a common disease which causes economic and social burden. Its incidence differs among the societies, with an incidence reported to reach up to 20% in developed countries. Eczema is the first allergic disease seen in the childhood, and it is recognized as a precursor for the development of atopic diseases such as asthma, allergic rhinitis, and food allergy in the forthcoming years of children. Increased incidence of eczema in recent years has led to new research in epidemiology, prevention, and intervention of this disease. It is no doubt important to treat itching, rash, and excoriation of the skin; however, treatment of pediatric eczema should not be considered only as a treatment of skin lesions. Considering skin treatment as the tip of the iceberg, proper management of the allergic processes can be accepted as the rest of the iceberg. The role of probiotics in the prevention of atopic eczema is yet to be clarified. Evidence presented by existing studies suggesting that probiotics may prevent pediatric eczema is not strong enough. A positive effect, if any, may be related with onset time, dose, duration, and use of specific probiotics. To date, there is no strong evidence for use of probiotics in the treatment of eczema; however, administration of probiotics in breast-feeding mothers in the prenatal period and in infants in the postnatal period can be accepted as a safe and helpful option in the prevention of eczema. Nevertheless, there are still questions to be answered in the future about probiotic administration for eczema. Clinical use of probiotics will gradually become more widespread when these questions are answered. Based on current information, the administration of probiotics for pediatric eczema topic is addressed in this review.

Cord-blood 25-hydroxyvitamin D levels and risk of early-onset neonatal sepsis: a case-control study from a tertiary care center in Turkey.

UNLABELLED: Vitamin D has been linked with immunity, and the immunomodulatory role of this molecule in regulating key elements of the immune system has become an area of intense scientific investigation. We designed a case-control study to investigate whether neonates with early-onset neonatal sepsis (EONS) had lower levels of vitamin D. The primary exposure for the analysis in the study was the cord-blood level of 25-hydroxyvitamin D (25(OH)D). Of the 2571 live births occurring during the 18-month study period, 53 infants were admitted to the neonatal intensive care unit with suspected EONS. After clinical and laboratory confirmation, 40 newborns with EONS and 43 controls were analyzed. Cord-blood 25(OH)D levels of infants in the study group were significantly lower than that of the control group (median 12.6 ng/mL (3.1-78.9) vs. 21 (5-118); p = 0.038, respectively). In multivariate models, a low cord-blood 25(OH)D level (<30 ng/ml) was associated with an increased risk of EONS (OR = 5.6; 95% CI = 1.3-23.5). CONCLUSION: Cord-blood 25(OH)D levels of neonates with EONS were significantly lower than that of the healthy controls, and a low level of cord-blood vitamin D was found to be associated with an increased risk of EONS. Further studies are warranted to confirm this association.

An abrupt increment in the respiratory rate is a sign of neonatal pneumothorax.

OBJECTIVE: The objective of the present study was to investigate the early clinical signs of neonatal pneumothorax. METHODS: A case-control study at a level III referral center from 2006 to 2012 was conducted. For each neonate with pneumothorax (Group I), one control subject (Group II) was identified by selecting an infant born within the same week with a gestational age of ± 7 days and with a birth weight within 10% of the index case. The primary outcome was to investigate the clinical findings preceding the onset of pneumothorax. Secondary outcome was to assess the risk factors. RESULTS: Of the 1375 infants admitted, 39 had a pneumothorax. Patients with pneumothorax showed significantly increased respiratory rates preceding the definitive diagnosis when compared with control patients (median: 16 (0-58) versus 4 (0-10); p < 0.001). An increase in the respiratory rate was found to be a significant clinical parameter preceding the diagnosis of pneumothorax (odds ratio (OR): 1.47, 95% confidence interval (CI): 1.12-2.14, p < 0.001; R(2) = 0.80). Sensitivity and specificity of this sign were found to be 77 and 90%, respectively. CONCLUSION: An abrupt increase in the respiratory rate would be used as a reliable parameter to help determine an impending pneumothorax in neonates.

Neonatal inflammatory submandibular sialadenitis associated with prenatal methyldopa exposure.

Inflammation of a salivary gland is an uncommon condition in the neonatal period, and an isolated form of submandibular acute inflammatory sialadenitis is an exceptionally rare phenomenon. Among various conditions that might lead to submandibular acute inflammatory sialadenitis, maternal use of drugs during pregnancy should be questioned as there may be possible associations. Herein, we describe a late preterm infant who presented with a large submandibular mass. After excluding possible pathogenic causes, maternal use of methyldopa was believed to be the only factor associated with this condition. To the best of our knowledge, no such relationship has been documented in previously published literature.

A descriptive study of transient neonatal feeding intolerance in a tertiary care center in Turkey.

OBJECTIVE: To investigate the characteristic features of transient neonatal feeding intolerance (TNFI) during the hospitalization for birth in the maternity ward. DESIGN: A prospective follow-up study. SETTING: Maternity ward and neonatal intensive care unit (NICU) in an academic medical center. PARTICIPANTS: Term (≥ 37-weeks gestation) infants admitted to the neonatal intensive care unit with recurrent vomiting and refusal to feed between January and December 2011. These infants were prospectively followed-up at 1, 2, 4, 6 months of age in the outpatient clinic. RESULTS: During the study period 1280 infants were evaluated in the maternity ward. Forty-eight (3.75%) neonates with repeated vomiting and refusal to feed were hospitalized from the maternity unit to the NICU Level I on the first postnatal day for further investigation. All infants started vomiting in the first day (median 5.75 hours; interquartile range: 1-24) and recovered by the 48(th) postnatal hour (median 27.5 hours; interquartile range: 14-48 hours). Laboratory and imaging studies showed no abnormalities. After discharge, 6-month follow-up of these infants showed no vomiting or feeding intolerance during well-child visits. CONCLUSIONS: Infants with TNFI can be managed with close observation and supportive measures if they have no other indications of underlying disease. We believe that expectant management and supportive measures under skilled nursing care will prevent unnecessary diagnostic evaluation, mother/infant separation, and prolonged hospital stay.

Decreased mean platelet volume in children with acute rotavirus gastroenteritis.

BACKGROUND: The contribution of platelets to the inflammatory response via several platelet derived mediators is well recognized. The role of mean platelet volume (MPV) in infectious and inflammatory disorders, however, has not yet been well-established. While some of the previous studies demonstrated that MPV acted as a positive acute phase reactant, several others suggested its role as a negative acute phase reactant. In the current study, we aimed to assess the role of MPV as an acute phase reactant in children with rotavirus gastroenteritis. METHODS: We undertook a prospective, randomized, controlled, cross-sectional study and enrolled children diagnosed with acute rotavirus gastroenteritis and healthy controls (HC), between August and November 2012. Children with acute gastroenteritis were assigned either in the rotavirus-positive acute gastroenteritis (RPAG) or in the rotavirus-negative acute gastroenteritis (RNAG) group depending on their stool antigen results. Patients were also classified into two groups based on their Vesikari score (< 11: non-severe and ≥ 11: severe). Complete blood count and C-reactive protein (CRP) levels were assessed for all patients. We compared MPV between RPAG, RNAG and HC groups and investigated the association, if any, among MPV, platelets, white blood count and CRP. RESULTS: In total 100 RPAG (54 males; mean age: 38.74 ± 41.45 months), 100 RNAG (58 males; mean age: 32.84 ± 29.64 months) children and 100 HC (43 males; mean age: 33.21 ± 32.55 months) were enrolled into the study. Mean platelet counts were well-matched among groups (p > 0.05). We observed a steady decline in MPV (fL) in the HC, RPAG and RNAG groups (median 7.80, 7.35 and 7.30, respectively; p < 0.0001). We did not find an association between MPV and the clinical score of gastroenteritis (p > 0.05). CONCLUSION: We found that MPV could be used as an acute phase reactant in children with rotavirus gastroenteritis. We believe that the current study will contribute to our understanding of MPV as an inflammatory marker.

A Rare Cause of Chronic Headache that May Be Misdiagnosed as Migraine: Chronic Carbon Monoxide Poisoning.

Differential diagnosis of primary headache disorders can be challenging for physicians. Although the association of headache with acute carbon monoxide intoxication is very well-defined, in refractory nonspecific headaches associated with chronic low dose exposure to carbon monoxide, CO intoxication is usually overlooked, mostly due to vague symptoms. Herein we present a 15-year-old female patient with chronic carbon monoxide poisoning who was undergoing two years of follow-up care for migraines. Chronic carbon monoxide intoxication may mimic the episodic nature and familial predisposition of migraine attacks. Normal carboxyhemoglobin levels do not exclude the diagnosis, and smoking is a confounding factor. In emergency rooms, patients presenting with headaches had higher levels of carboxyhemoglobin, but, as far as we know, there have been no studies investigating carboxyhemoglobin levels in migraine patients. Chronic carbon monoxide poisoning should be suspected in migraine patients, especially if the attacks occur during winter months.

Social prejudice hindering proper use of car safety seats.

The compliance of parents with child passenger safety (CPS) has been mainly explained by their level of knowledge. Social, ethnic and cultural factors have not been investigated in detail. This study investigated the rate of compliance of parents with CPS guidelines, as well as the factors hindering it. Parents of infants aged 2-10 days were enrolled. The proportions of families obtaining a car safety seat (CSS; 57%) and complying with CPS recommendations (2%) were very low. Most of the parents thought CSS were harmful for infants (mother, 57%; father, 63%), despite having already purchased one. Parents believed their children to be too small to use CSS and cannot sit in CSS because they should lie flat on their backs at all times. These prejudices may be due to the social and cultural circumstances specific to Turkey, or corresponding findings may be found in countries with similar socioeconomic status.

The utility of special radiological signs on routinely obtained supine anteroposterior chest radiographs for the early recognition of neonatal pneumothorax.

BACKGROUND: Bedside chest radiographs used for the confirmation of diagnosis of pneumothorax in the neonatal intensive care unit (NICU) are routinely obtained in the supine position. However, pneumothoraces may not appear in the classically described forms on these radiographs, resulting in a delayed diagnosis. OBJECTIVE: To assess the utility of special radiological signs in the neonatal population for the early recognition of pneumothorax. METHODS: A case-control study was conducted at a level III referral center from January 2006 to December 2012. For each neonate with pneumothorax, one infant was selected for the control group. A senior radiologist and neonatologist experienced in reading chest radiographs evaluated each radiograph for the presence of special radiological signs. RESULTS: Of the 1,375 infants admitted to the NICU during the study period, 39 had a pneumothorax. A total of 223 radiographs were scored and 46% of the neonates were found to have occult pneumothoraces before they were clinically diagnosed. Twenty-six percent had a single sign detected on a radiograph, whereas 20% had multiple signs. The time interval between the appearance of these signs and clinical diagnosis ranged between 0.5 and 27 h. CONCLUSIONS: The present study shows that the recognition of these signs would assist the physician in identifying occult pneumothorax earlier in its course. Physicians dealing with critically ill infants should ensure that they can recognize these radiological signs.

Is PFAPA syndrome really a sporadic disorder or is it genetic?

Periodic fever syndromes are a group of disorders sharing similar symptoms, characterized primarily by regularly recurring fevers. PFAPA syndrome, one of the members of this group of disorders, is a clinical entity of unknown etiology which is frequently seen in the early childhood. Currently, the pathogenesis and the genetic basis of most of the disorders in the periodic fever spectrum are known, other than that of PFAPA syndrome. Although, classically PFAPA syndrome is known as a sporadic disease, we propose that it is not sporadic. We think that PFAPA syndrome may be an inherited disease and this hypothesis is supported by the clinical mimicry of PFAPA syndrome with other periodic fever syndromes with well-known genetic transmissions, frequent occurrence of the condition in members of the same family and emergence of common genetic mutations in the periodic fever syndrome spectrum. Moreover, our clinical observation that most of the patients diagnosed with PFAPA syndrome were of the same families strongly suggest a probable genetic transmission of this disorder. We have decided to discuss this hypothesis to contribute to the literature and assist our colleagues who are dealing with this commonly overlooked and often misdiagnosed disorder.

Do not overlook an umbilical cord hernia before clamping.

An umbilical cord hernia is a rare midline abdominal defect. These masses may be easily overlooked at birth, which may result in an intestinal injury due to careless proximal application of the cord clamp. Herein, we present a newborn infant with an umbilical cord hernia who was managed by primary closure of the lesion.

Neuron-specific enolase and S100B protein in children with carbon monoxide poisoning: children are not just small adults.

INTRODUCTION: The aim of this study was to evaluate the role of S100B protein and neuron-specific enolase (NSE) in children with carbon monoxide (CO) poisoning. METHODS: In this prospective, case-controlled study, children with CO poisoning were recruited. Patient demographics features and Glasgow Coma Scale (GCS) were recorded. Blood samples were collected from all children with CO poisoning at their admission to the hospital and at 3 and 6 hours after admission. Levels of NSE and S100B were measured. The control group consisted of age-matched healthy children. RESULTS: A total of 30 children with CO poisoning (mean age, 7.88 ± 3.75 years; 17 boys) and 30 healthy children (mean age, 8.16 ± 3.05 years; 7 boys) were enrolled in the study. Mean carboxyhemoglobin level (%) measured at admission was 30.05 ± 8.00. Serum NSE levels of the children with CO poisoning were significantly higher than those of children from the control group at 0 hour and also at 3 and 6 hours (P < .001, P = .001, and P = .005, respectively). Serum S100B protein levels were similar between the 2 groups at 0 and 3 and 6 hours (P > .05). Serum NSE levels of patients with CO poisoning demonstrated a negative correlation with the admission GCS scores. No correlation was found between GCS scores and S100B protein levels. CONCLUSION: We have shown that NSE levels increase in CO-associated hypoxic brain damage in accordance with clinical findings. We have also found that, contrary to the studies conducted on adults, S100B protein levels do not increase in response to hypoxic brain damage.
