Objective: Continued progress in our understanding of the food protein-induced allergic proctocolitis (FPIAP) will provide the development of diagnostic tests and treatments. We aimed to identify precisely the clinical features and natural course of the disease in a large group of patients. Also, we investigated the predicting risk factors for persistent course since influencing parameters has not yet been established., Methods: Infants who were admitted with rectal bleeding and had a diagnosis of food protein-induced allergic proctocolitis in 5 different allergy or gastroenterology outpatient clinics were enrolled. Clinical features, laboratory tests, and prognosis were evaluated. Risk factors for persistent course were determined by logistic regression analyses., Results: Among the 257 infants, 50.2% (n = 129) were girls and cow's milk (99.2%) was the most common trigger. Twenty-four percent of the patients had multiple food allergies and had more common antibiotic use (41.9% vs 11.8%), atopic dermatitis (21% vs 10.2%), wheezing (11.3% vs 1.5%), colic (33.8% vs 11.2%), and IgE sensitization (50% vs 13.5%) compared to the single-food allergic group (P < 0.001, P = 0.025, P = 0.003, P < 0.001, respectively). In multivariate logistic regression analysis, presence of colic (odds ratio [OR]: 5.128, 95% confidence interval [CI]: 1.926-13.655, P = 0.001), IgE sensitization (OR: 3.964, 95% CI: 1.424-11.034, P = 0.008), and having allergy to multiple foods (OR: 3.679, 95% CI: 1.278-10.593, P = 0.001] were found to be risk factors for continuing disease after 1 year of age., Conclusion: Although most children achieve tolerance at 1 year of age, IgE sensitization, allergy to multiple foods, and presence of colic were risk factors for persistent course and late tolerance. In this context, these children may require more close and extended follow-up.

Background: Hypersensitivity reactions (HSRs) to chemotherapeutic agents have been increasingly documented., Objective: The aim of this study was to investigate HSRs due to chemotherapeutics agents in childhood., Methods: From January 2007 to June 2019, the patients who were treated for neoplastic diseases in our hospital were evaluated. Patients who developed a HSR to a chemotherapeutic agent were included., Results: Fifty-seven patients with 65 reactions (60% anaphylaxis) were evaluated. Escherichia coli asparaginase was responsible for 38 (58.5%) of these 65 reactions. The other agents were polyethylene glycol (PEG)-asparaginase (n = 11), etoposide (n = 7), methotrexate (n = 4), carboplatin (n = 4), and procarbazine (n = 1). Of the 38 patients who had a reaction to E coli-asparaginase, 33 patients received alternative treatment (PEG-asparaginase or Erwinia asparaginase), 3 patients continued with desensitization, and 2 patients underwent bone marrow transplantation. Five patients who had an initial reaction to PEG-asparaginase continued their treatment with Erwinia asparaginase or E coli asparaginase uneventfully. Of 7 patients who had a reaction to etoposide (4 had anaphylaxis), 3 patients continued with desensitization, and 2 patients used the drug with premedication and prolonged infusion. Two patients had anaphylaxis with methotrexate. Treatment was continued with desensitization in 1 patient and methotrexate treatment was discontinued in the other patient. Of the 4 patients with carboplatin hypersensitivity, 2 had anaphylaxis. Desensitization was performed in 2 patients. One patient had procarbazine HSR, drug was given with premedication., Conclusion: Among all chemotherapeutic agents reviewed in our study that caused HSRs, asparaginase was the most common culprit agent in children. Most of reactions are immediate type. Many of the patients can take their treatment by drug replacement or desensitization., (Copyright © 2020 American College of Allergy, Asthma & Immunology.

Aim: To introduce a traumatic brain injury (TBI) patient who underwent stem cell transplantation (SCT) in order to minimize the remaining injury deficiencies., Material and Methods: This study included a 29 years old male who had TBI resulting from a vehicle accident which took place one and a half years ago. The participant received six doses of intrathecal, intramuscular, and intravenous transplantation of Wharton?s jellv-derived mesenchymal stem cells (WJ-MSCs) at a goal dose of 1xl0 < sup > 6 < /sup > / kg respectively for each route of administration for six months., Results: No important negative effects were reported. The patients? speech, cognitive, memory and fine motor skills were improved. The efficacy of treatment with SCT was assessed with cranial magnetic resonance imaging (MRI), computed tomography (CT) screening, and electroencephalography (EEG)., Conclusion: SCT can have a promising future as a medical approach in recurrent TBI.

Aim: To elucidate the characteristics of kyphoplasty in correlation with spinal metastasis., Material and Methods: Data of patients treated by kyphoplasty between January 2017 and December 2019 were reviewed retrospectively. Preoperative prophylactic antibiotics and low-molecular-weight heparin injections were performed. Postoperative follow-up was conducted at least 24 hours after the procedure. All patients were treated under sedoanalgesia. Bone biopsies were collected from all patients., Results: One hundred ninety-nine vertebra fractures were treated in 130 patients. The mean age of the patients was 65.27 ± 8.79 years (18?90 years) and 66 patients were male (50.7%). Forty-five patients had osteoporosis, six patients showed malignancy, and osteomyelitis was found in three patients, while the others? presentations were secondary to trauma. Most commonly, the L1 (n=59), Th12 (n=45), and L2 (n=34) levels were found to develop vertebral fractures. Forty patients had multiple levels of vertebral fracture, with a higher rate of osteoporosis (n=24; 60%). Three patients showed undiagnosed oncologic disease with an initial diagnosis of acute fracture following minor trauma, while the primary oncologic diagnosis was established by bone biopsy taken during the routine procedure in each procedure (e.g., plasmacytoma, lymphoma, adenocarcinoma of the lung). None of the patients developed an infection due to kyphoplasty, permanent neuromotor deficit, or mortality. The mean postoperative hospital length of stay was 1.6 days., Conclusion: Bone biopsy should be performed to diagnose early spinal metastases. Although an accurate bone biopsy may not be obtained from some patients, particularly from those with osteoporosis, performing bone biopsy during the procedure does not cause time loss or any other complications, and protects the surgeon from possible medicolegal problems.

Aim: To explore the anatomic features of the neural foramen in particularly at the T12-L1 level in order to assess reveal the safety and efficiency of the endoscopic transforaminal approach for paramedian and foraminal disc herniations at this level., Material and Methods: The study included 15 fresh human cadavers. The soft tissues were removed at the T12-L1 level and bony tissues, were exposed including the transverse processes. The bilateral facets and pars interarticulares at this level were resected revealing the foraminal anatomy and exiting roots. The anatomical structures constituting the triangular safe working zone (TSWZ) were explored. The nerve root length, nerve root width, nerve root angle, TSWZ height, and base of TSWZ base, nerve root width, nerve root angle and disc height were recorded., Results: The root length is the hypotenuse of the TSWZ between the axilla of the exiting root and the lateral margin of the pedicle, and the mean root length was 14.94 ± 2.45 mm. The dural height is the interval between the axilla of the exiting nerve root axilla and the superior end plate of the caudal vertebra, and the mean of the dural height was 10.95 ± 1.74 mm. The base of TSWZ is the distance between the lateral margin of the dural sac and the medial margin of the exiting root, and the mean measurement for the base measurement was 11.83 ± 2.26 mm., Conclusion: According to the results data from our cadaveric study, we believe that Kambin’s triangular working zone is a safe area to consider for the endoscopic transforaminal approach at the T12-L1 level, especially for paramedian and foraminal disc herniations.

Aim: To reveal difficulties in differential diagnosis of some cases of cerebrovascular events (CVEs) and malignant primary brain tumors (MBTs) even a multidiciplinary evaluation in grand rounds., Material and Methods: This study retrospectively analyzed the patient archives from January 2017?December 2019. The records of 572 patients discussed in these meetings were examined. A total of 8 patients having a challenge in differential diagnosis were detected., Results: This study has included 8 cases in which neurology-neurosurgery-neuroradiology clinicians have difficulty in differentiating CVE and MBT. In the present study, three patients were evaluated with a preliminary diagnosis of hemorrhagic CVE in the emergency room. Since degradation products of hemoglobin have prevented advanced imaging methods to diagnose in two patients, these patients have been followed closely. The correct diagnosis could be made through the scan performed during control follow-ups The preliminary diagnosis of seven patients was CVE, but they received the MBT diagnosis during the follow-up. One patient was thought to have MBT initially; however, he/she was diagnosed with CVE after an advanced examination and close follow-up., Conclusion: Despite developing medical imaging methods and diagnostic studies, there are still some difficulties in making differential diagnosis of CVEs and MBTs. In some patients, further examination and imaging methods may be needed such as magnetic resonance imaging-spectroscopy (MRI-S), perfusion magnetic resonance imaging (Per-MRI), digital substratioangiography (DSA). Despite all these neuroradiological examinations and multidiciplinary evaluation, distinction between CVE and MBT may be difficult, and medicolegal problems may be encountered.

Aim: To examine the morphological structure of anterior lumbar spinal region., Material and Methods: Fifteen fresh human cadavers were studied in our forensic medicine institution. Within the first 24 hours after death, cadavers were subject to a routine autopsy, by which the intestines were removed and the structures adjacent to the lumbar arteries (LAs) were examined. The following characteristics of the LA were examined and recorded: diameter, number of LA, intervertebral disc, and vertebral corpus relationship, and LA anatomical variations., Results: In 14 of the 15 cadavers (93.3%), the first four LAs originated from the abdominal aorta. In one (6.7%) cadaver, the fourth LA originated from the right aortic trunk together with the median sacral artery (MSA), and this was observed only in the right side. In one cadaver, the first LAs emerged as a common trunk. Twelve cadavers did not have a fifth LA. In one cadaver (6.7%), the fifth LAs emerged as in a pair, distally from the origin of the MSA. Two cadavers (13.3%) had fifth LAs that emerged from the common trunk with the MSA and this occurred only on the right side. LAs which emerged from the right side of the abdominal aorta passed under the inferior vena cava. Of the first four LA, the third LA had the largest vessel diameter, and the first LA had the narrowest vessel diameter. Fifth LAs had one of the narrowest vessel diameters of all LAs., Conclusion: We consider that anatomical study of LAs using fresh cadavers can be useful to ensure safer anterior lumbar spinal surgeries.

Background/aim: Ig level assessment is frequently used in the diagnosis and follow-up of immunodeficiency, as well as in studies investigating the prevalence of low serum Ig level in specific diseases., Materials and Methods: Patients who underwent Ig testing in the inpatient and outpatient clinics of our hospital in the years 2010–2016 were included. The Ig levels of the patients were assessed separately according to two reference systems commonly used in Turkey and another reference system used in the USA., Results: A total of 20,138 patients (57.6% male) were included in the study. The median age of the patients was 55.7 months (interquartile range: 23.1–96.7). According to the reference intervals determined by Tezcan et al., 30.6% of the patients were deficient in one or more Ig values. This rate was 4 times higher than those based on the reference intervals determined by Aksu et al. (7.7%) and those in the Nelson Textbook of Pediatrics (6.8%). We also determined that the frequency of low Ig levels with three reference systems, Conclusion: In this study, we found that the rates of low Ig level in a group of pediatric patients differed significantly when evaluated using three different reference systems for age-related serum Ig levels

Objective: To investigate the short- and long-term effects of ganglion impar radiofrequency thermocoagulation (RFT) treatment in patients with chronic coccydynia., Methods: We retrospectively analyzed the medical records of patients who underwent RFT of the ganglion impar between 2009 and 2011. Pain intensity visual numeric scale (VNS) scores and Euroqol 5D (EQ-5D) index scores were recorded pre-intervention and post-intervention at the first, sixth, and twelfth months. The differences between pre-procedural VNS scores and post-procedural VNS scores at the first, sixth, and twelfth months were evaluated. The success of the intervention was recorded as the percentage difference between the pre-intervention VNS scores and post-intervention VNS scores at the first, sixth, and twelfth months., Results: The mean age of the patients, including 11 females (55%) and 8 males (45%), was 48.7 ± 14.3 years. The average follow-up duration was 17.3 ± 2.9 months. Statistically significant differences were observed between the pre- and post-procedure VNS scores (P < 0.0001). Improvements in VNS scores were correlated with improvements in EQ-5D index scores. Mid-term (sixth month) and long-term (twelfth month) evaluations after the intervention revealed that 67.4% and 61.1% of the patients had successful outcomes, respectively., Conclusion: Our data suggested that RFT of the ganglion impar in patients with chronic coccydynia resulted in effective outcomes, and patients who responded to RFT had significantly lower post-RFT pain scores., (© 2018 World Institute of Pain.)

Background: Children may be referred to pediatric allergy clinics for reactions to multiple drugs. Multiple drug hypersensitivity (MDH) is defined as immunologically-mediated hypersensitivity to 2 or more chemically different drugs., Objective: The aim of this study is to report the allergy workup results of children who had a history of potential hypersensitivity reactions to 2 or more unrelated drugs., Methods: This study was conducted in the Pediatric Allergy and Immunology department of our hospital. Children who described hypersensitivity reactions to 2 or more drugs were included and were evaluated by allergy workup (skin and/or provocation tests) between January 2011 and July 2016., Results: During the study period, 886 children were evaluated for a history of drug intolerance. Of these children, 73 (8.2%) had a history of drug reactions to 2 or more chemically different drugs. The median age of the children who had a history of reactions to 2 or more drugs was 7.8 (min-max: 2.5-16.4) years, and 59% (n = 43) were male. Among the suspected drugs, antibiotics (65.9%) ranked first, and nonsteroid anti-inflammatory drugs (34.1%) were the second. All 73 children were evaluated with skin or provocation tests with the suspected drugs, and MDH was confirmed in only 2 (2.7%) children., Conclusion: Multiple drug hypersensitivity is uncommon in children. The incidence and prevalence of MDH may vary with the specific population studied. Evaluating children with a history of MDH, by performing drug hypersensitivity testing, will help avoid the morbidity associated with unnecessary drug avoidance., (Copyright © 2018 Elsevier Ltd.

Background: Antiepileptic drugs (AEDs) can cause hypersensitivity reactions during childhood. Studies report a wide clinical spectrum of reactions with AED use, ranging from a mild rash to severe cutaneous reactions., Objective: To determine the prevalence and clinical features of AED hypersensitivity reactions during childhood., Methods: Patients in our pediatric neurology clinic who were prescribed an AED for the first time between November 2015 and November 2016 were monitored and those who developed skin rash during this period were evaluated., Results: A total of 570 patients were evaluated. The median age of the patients was 8.86 (interquartile range, 4.2-13.7) years, and 55.8% (318) of patients were male. The most frequently used AEDs were valproic acid (42%, n = 285) and carbamazepine (20.4%, n = 116). Hypersensitivity reactions to AEDs developed in 5.4% of patients. Of these patients, 71% (29) had cutaneous drug reactions and 29% (9) had severe cutaneous drug reactions; 61.3% (19) were using aromatic AEDs, and the leading suspected AED was carbamazepine (45.2%). Comparison of patients who did and did not develop AED hypersensitivity showed that hypersensitivity was more frequent among patients who were younger than 12 years, who used aromatic AEDs, or who used multiple AEDs. In addition, according to regression analysis results, aromatic AED use significantly increased the risk of AED hypersensitivity (P < .001)., Conclusions: Although allergic reactions to AEDs are rare, they are of significance because they can cause life-threatening severe cutaneous drug reactions. Therefore, patients receiving AEDs, especially aromatic AEDs, must be monitored closely., (Copyright © 2018 American Academy of Allergy, Asthma & Immunology. Published by Elsevier Inc.

Wharton's jelly-derived mesenchymal stem cells (WJ-MSCs) have been introduced as a possible therapy in hypoxic-ischemic encephalopathy (HIE). We report a 16-year-old boy who was treated with WJ-MSCs in the course of HIE due to post-cardiopulmonary resuscitation. He received a long period of mechanical ventilation and tracheostomy with spastic quadriparesis. He underwent the intrathecal (1×10 6 /kg in 3 mL), intramuscular (1×10 6 /kg in 20 mL) and intravenous (1×10 6 /kg in 30 mL) administrations of WJ-MSCs for each application route (twice a month for 2 months). After stem cell infusions, progressive improvements were shown in his neurological examination, neuroradiological, and neurophysiological findings. To our best knowledge, this is a pioneer project to clinically study the neural repair effect of WJ-MSCs in a patient with HIE.

Background: Results of epidemiologic studies have determined several risk factors for asthma in school-age children., Objective: To examine whether parental and perinatal risk factors, along with infantile feeding patterns, were associated with asthma in children with grass pollen allergy and allergic rhinitis., Methods: We retrospectively analyzed the data of our cohort, which consisted of children with allergic rhinitis. Only children with grass pollen sensitization were enrolled. A detailed questionnaire regarding demographic features and perinatal events was given to the parents., Results: A total of 293 children (200 boys [68.3%]; with median age, 10.2 years [interquartile range {IQR}, 7.4-13.0 years]) were included. A total of 109 children (37.2%) had accompanying asthma. The median age of onset of rhinitis symptoms was earlier (5.3 years [IQR, 4.0-8.0 years] versus 7.0 years [IQR, 5.0-10.0 years]; p = 0.001), histories of prematurity (16.7 versus 6.5%; p = 0.006), preeclampsia (5.5 versus 0%; p = 0.001), neonatal intensive care unit admission (15.1 versus 6.0%; p = 0.01), phototherapy (17.9 versus 7.1%; p = 0.004), early formula feeding (58.7 versus 41.2%; p = 0.006), and parental asthma (25.0 versus 11.4%; p = 0.002) were more frequent in children with asthma. Multivariate logistic regression analysis revealed prematurity (odds ratio [OR] 2.78 [95% confidence interval [CI],1.24-6.24]; p = 0.013), history of formula feeding (OR 1.81 [95% CI, 1.09-3.01]; p = 0.022), and parental asthma (OR 2.37 [95% CI, 1.22-4.63]; p = 0.011) were associated with asthma in school-age children with grass pollen-induced allergic rhinitis., Conclusion: Close monitoring of patients with these risk factors may help with an earlier diagnosis of asthma and prompt initiation of therapeutic interventions in children with allergic rhinitis and who were sensitized to grass pollen.

Background: Nonsteroidal anti-inflammatory drugs (NSAIDs) are the second-most frequent drug type to cause hypersensitivity reactions in children. Asthma is one of the risk factors for NSAID hypersensitivity (NSAID-H) in adult patients. There are limited number of studies evaluating NSAID-H among children with asthma. Our aim was to assess the frequency of confirmed NSAID-H and evaluate the classification of NSAID-H in children with asthma., Methods: Patients followed with a diagnosis of asthma in our Pediatric Allergy Clinic were evaluated for NSAID-H. Patients were questioned whether they had used NSAIDs, and if they experienced any reaction with these drugs. A control group was also questioned for reactions to NSAID use., Results: 976 children with asthma and 2,000 healthy children as a control group were included in this study. The mean age of the patients with asthma was 10.61 ± 4.21 years and 59.5% were male. Ten (1%) had a reaction history to NSAIDs. NSAID-H was confirmed in 9 (0.9%) who were tested with the suspected drugs. Six of these were classified as "single NSAID-induced urticaria/angioedema or anaphylaxis" and 3 were classified as "NSAIDs-exacerbated respiratory disease." In the control group, only 1 subject had a reaction history to acetylsalicylic acid and no reaction developed in the provocation test., Conclusions: In our study, NSAID-H was found more frequent in children with asthma than in the control group. Children with asthma should be evaluated for reactions to NSAIDs during hospital visits., (© S. Karger AG, Basel.)

Objective: This study aimed to analyze the effect of human Dental Pulp-Neural Crest Stem Cells (hDP-NCSCs) delivery on lesion site after spinal cord injury (SCI), and to observe the functional recovery after transplantation., Methods: Neural Crest Stem Cells (NCSCs) were isolated from human Dental Pulp (hDP). The experimental rat population was divided into four groups (n = 6/24). Their behavioral motility was scored regularly. After 4-weeks, rats were sacrificed, and their spinal cords were examined for Green Fluorescent Protein (GFP) labeled hDP-NCSCs by immunofluorescence (IF) staining., Results: In early post-injury (p.i) period, the ultrastructure of spinal cord tissue was preserved in Group 4. The majority of cells forming the ependymal region around the central canal were found to be hDP-NCSCs. While the grey-and-white-matter around the ependymal region was composed of e.g. GFP cells, with astrocytic-like appearance. The scores showed significant motor recovery in hind limb functions in Group 4. However, no obvious change was observed in other groups., Conclusion: Cells e.g., mesenchymal (Vimentin+) which express GFP+ cells in the gray-and-white-matter around the ependymal region could indicate the potential to self-renewal and plasticity. Thus, transplantation of hDP-NCSCs might be an effective strategy to improve functional recovery following spinal cord trauma (Fig. 10, Ref. 32).

Background: Despite the increasing frequency of anaphylaxis, there is inadequate information on the etiology and clinical features in various countries, regions and age groups, especially in developing countries., Objective: Our aim is to assess the etiology and clinical findings of anaphylaxis in Turkey. Gathering reliable data about the etiology and clinical findings of anaphylaxis in the general population will decrease the related morbidity and mortality., Method: We obtained the names and phone numbers of individuals who had been prescribed an epinephrine auto-injector with a diagnosis of anaphylaxis from ministry of health. Demographic data, clinical history of the first episode of anaphylaxis including the triggering agent, clinical findings, course of hospitalization, and the management of anaphylaxis were obtained by phone survey., Results: A total of 843 patients with a mean age of 21.4±17.3 years were evaluated. There was a significant male predominance among children younger than 10 years of age but a female predominance in older subjects. The most common causes of anaphylaxis were foods(40.1%) in children and bee venom(60.8%) in adults. The biphasic reaction rate was 4.3% and the median length of stay at an emergency department was 4.0 hours. Almost 60% of the patients had recurrent anaphylaxis episodes. Only 10.7% of the cases were prescribed an epinephrine auto-injector at their first anaphylaxis episode and only 59.2% of the patients were referred to an allergist during discharge from the emergency department., Conclusions: In Turkey, bee venom was the most common cause of anaphylaxis, followed by food and drug. While more than a half of patients reported recurrent attacks; only 10% had been prescribed epinephrine auto-injector kit after their first episode. Strategies to improve the anaphyalxis management are therefore urgently required.

Dietary intake of omega-3 polyunsaturated fatty acids, including eicosapentaenoic acid (EPA) and docosahexaenoic acid (DHA), has been reported to have beneficial cardiovascular effects. However, little is known about the effect of EPA and DHA on human vascular tone. Therefore, the aim of this study is to evaluate the effect of EPA and DHA on vascular tone of the human saphenous vein (SV) obtained from patients undergoing coronary bypass operation under normal and inflammatory conditions. Moreover, we aimed to investigate the effect of EPA and DHA on the release of inflammatory mediators from SV. Pretreatment of SV with EPA and DHA (100μM, 18h) decreased the contractile response of SV to norepinephrine (NE) under normal and inflammatory conditions. Moreover, EPA and DHA pretreatment diminished increased Monocyte Chemoattractant Protein-1 (MCP-1) and Tumor Necrosis Factor-alpha (TNF-α) release from SV under inflammatory conditions. In conclusion, our results suggest that EPA and DHA pretreatment may be beneficial to counteract graft vasospasm and vascular inflammation in SV which are important factors in graft failure development. Therefore, dietary intake of EPA and DHA may have potential clinical applications in improving coronary bypass graft patency., (Copyright © 2017 Elsevier Inc. All rights reserved.)

Background: Beta-lactam antibiotics (BLA) are the most commonly prescribed antibiotics and are responsible for the majority of immediate hypersensitivity reactions to drugs in children. Cross-reactivity is important in hypersensitivity to BLAs because these drugs all share a common beta-lactam structure and some share similar side chains., Objective: The aim of this study was to evaluate the clinical characteristics of patients who are diagnosed with immediate-type BLA hypersensitivity and frequency of patients with side chain hypersensitivity, "selective responders.", Methods: The study included patients who were diagnosed with immediate-type BLA hypersensitivity between January 2011 and May 2016 in a pediatric allergy outpatient clinic. The patients who had negative penicillin test (minor determinant mixture, benzylpenicilloylpoly-L-lysine, penicillin G) results and could tolerate penicillin V and/or BLAs with dissimilar side chains but had positive skin and/or provocation test results with the suspected drug were diagnosed as selective responders., Results: During the study period, 357 patients (55.2% girls) were admitted to our clinic with suspected immediate-type BLA hypersensitivity. Parents of 11 patients did not give consent for an allergy workup with the suspected drug. Forty-five of the patients were diagnosed (45/346 [13%]) based on skin test or drug provocation test results. The most common susceptible agent was amoxicillin-clavulanate. Of the patients, 71.4% with a reaction to sulbactam-ampicillin /or amoxicillin-clavulanate and 93.7% with a reaction to cephalosporin were classified as selective responders., Conclusion: Among children with immediate BLA hypersensitivity, selective responders constituted an important group. Most of the patients with reactions to aminopenicillin and cephalosporins safely tolerated penicillin V and BLAs with dissimilar side chains after negative allergy workup results.

Background: The presence of sleep-disordered breathing (SDB) in children with asthma may cause difficult to control asthma., Objectives: The aim of this study was to determine the frequency of SDB in children with asthma, to evaluate its effects on asthma control and to assess the risk factors associated with the presence of SDB., Methods: Parents of children who Sleep Questionnaire (PSQ) and the Childhood Asthma Control Test (C-ACT). Asthma control level was assessed according to Global Initiative for Asthma (GINA). Same ear-nose-throat (ENT) specialist evaluated all patients. A 4-point tonsil grading method and adenoid-nasopharynx ratio were used to categorize tonsil and adenoid size, respectively., Results: A total of 408 children (275 male, 67.4%) with a mean age of 8.1 ± 3.2 years were included. Nearly 40% of asthmatic children were not-well-controlled according to GINA and 34.6% of all patients had SDB according to PSQ. Multivariate logistic regression analysis revealed that coexistence of SDB [OR: 6.62, 95% CI (4.21-10.41); p < 0.001)] and tonsillar hypertrophy [OR: 3.47; 95% CI (1.05-11.5); p < 0.041] were independent risk factors for not-well-controlled asthma in asthmatic children after other established contributors to asthma control were adjusted., Conclusions: Our study showed that SDB is a strong risk factor for not-well-controlled asthma in asthmatic children independent of other confounders. In addition, tonsillar hypertrophy may have a role in the association between SDB and not-well-controlled asthma in childhood.

Background: The severe cutaneous adverse drug reactions (SCARs) are rare but could be life-threatening. These include drug reaction with eosinophilia and systemic symptoms (DRESS), Stevens-Johnson syndrome, toxic epidermal necrolysis (TEN), and acute generalized exanthematous pustulosis., Objective: The purpose of this study was the evaluation of the clinical characteristics of patients with the diagnosis of SCARs., Methods: Patients who were diagnosed with SCARs between January 2011 and May 2016 by pediatric allergy clinics in the provinces of Ankara, Trabzon, Izmir, Adana, and Bolu were included in this multicenter study. Clinical and laboratory findings, the time between suspected drug intake and development of clinical findings, treatments they have received, and length of recovery time were recorded., Results: Fifty-eight patients with SCARs were included in this study. The median age of the patients was 8.2 years (interquartile range, 5.25-13 years) and 50% (n = 29) were males. Diagnosis was Stevens-Johnson syndrome/TEN in 60.4% (n = 35), DRESS in 27.6% (n = 16), and acute generalized exanthematous pustulosis in 12% (n = 7) of the patients. In 93.1% of the patients, drugs were the cause of the reactions. Antibiotics ranked first among the drugs (51.7%) and antiepileptic drugs were the second (31%) most common. A patient who was diagnosed with TEN developed lagophthalmos and a patient who was diagnosed with DRESS developed secondary diabetes mellitus. Only 1 patient with the diagnosis of TEN died., Conclusions: SCARs in children are not common but potentially serious. Early diagnosis and appropriate treatment of SCARs will reduce the incidence of morbidity and mortality., (Copyright © 2017 American Academy of Allergy, Asthma & Immunology.

Background/aim: IgA deficiency is the most common human primary immunodeficiency. The prevalence of allergic disorders and autoimmunity is thought to be increased in selective IgA deficiency (sIgAD). However, it is currently unclear if these disorders coincide within these families. We aimed to evaluate the frequency of allergic and autoimmune disorders in children with sIgAD and their first-degree relatives (FDRs)., Materials and Methods: The study included 81 children diagnosed with sIgAD and 274 of their FDRs. The presence of allergic and autoimmune disorders was evaluated and serum antithyroglobulin and antithyroid peroxidase levels were measured in both patients and their first-degree relatives., Results: The mean age of the patients was 9.9 ± 3.9 years. Among the patients with sIgAD, 45.7% of them had at least one allergic disorder and 17.3% of them had at least one autoimmune disorder. The frequencies of asthma, allergic rhinitis, and eczema in the FDRs of sIgAD patients were 10.9%, 9.1%, and 7.7%, respectively. Among their FDRs, 14.6% had autoimmunity, compared to an estimate of 5% in the general population., Conclusion: Increased frequency of allergic and autoimmune disorders in patients with sIgAD and their FDRs suggests a possible common predisposing genetic component for sIgAD and autoimmunity in these families.

Background: Complementary and alternative medicine (CAM) use has been increasing., Objective: To identify the factors associated with perceived benefit from CAM methods in back problems., Methods: The study was conducted on patients who practiced any CAM methods due to complaints of back pain. Social-demographic properties, details of CAM methods employed were questioned. Severity of pain was measured by visual analog scale (VAS); benefits were evaluated by the Likert scale. Hierarchical cluster analysis was used to discover relationships among variables., Results: In total, 500 patients (265 female, 235 male) were included in the study. Mostly used methods were herbal therapy (32%), balneotherapy (31%), cupping (19.4%) and massage-manipulation (19.2%). Of patients, 355 (71%) were satisfied. The variables associated with benefit finding were female gender, age, chronicity and severity of pain, high educational level, upper middle income status, use as a result of recommendation, dissatisfaction with conventional methods, residence in an urban area, non-herbal method use, being married, and social insurance (p < 0.005)., Conclusion: The majority of patients using CAM perceived benefits; in particular, women living in urban areas, highly educated, aged more than 40, who suffer from severe chronic back pain, may be more inclined to go to CAM therapists.

Background: Anaphylaxis is increasingly reported in infancy. Diagnosis and management of anaphylaxis is difficult, and data are limited in infants. The aim of the present study was to determine the clinical course and management strategies used for anaphylaxis in infancy., Methods: Patients attending to our clinic and who had anaphylaxis under 2 years old were evaluated. Sixty-three patients were enrolled for the study. The mean ± standard deviation age was 10.6 ± 6.1 months (median, 11 months)., Results: Anaphylaxis occurred at home in 48 infants (76.2%). Food was the most common causative agent (n = 52 [82.5%]), with cow's milk (n = 21 [40.4%]) and egg white (n = 13 [25%]) being the most frequent. Medication was the other causative agent (n = 9 [14.3%]), with antibiotics being the most frequent (n = 6 [66.7%]). The clinical manifestations were cutaneous (95.2%) and respiratory symptoms (79.4%). The median time lapse between contact and onset of symptoms was 10 minutes (5-15 minutes) (median, interquartile range [IQR] 25-75%). The total duration of symptoms was 2 hours (0.5-3 hours) (median, IQR 25-75%). Six patients had mild (9.5%), 40 moderate (63.5%), and 17 severe (27%) symptoms. A biphasic course was noticed in two infants (3.2%), with a symptom-free interval between a minimum of 30 minutes and a maximum of 4 hours. Forty-three (68.3%) received H1 antihistamines, 31 received corticosteroids (49.2%), and 23 received adrenaline (36.5%). Only one patient needed intensive care., Conclusion: This study provided detailed clinical information in the diagnosis of anaphylaxis in infants. Diagnosing and managing anaphylaxis are difficult in infancy. Arrangements for definition of symptoms should be made in the new anaphylaxis guidelines.

Aim: Conjoined nerve roots (CNR) can be damaged during lumbar disc surgery and lead to neuropathic pain due to excessive retraction. The purpose of this study was to investigate the factors that facilitate the identification of CNRs that can lead to the loss of fragments in the secondary axilla, nerve root injury or unpleasant surprises during lumbar disc surgery. Accordingly, we aimed to measure the thicknesses and exit angles of the nerve roots close to the pedicle to obtain scientific data regarding rare double roots., Material and Methods: The data of 612 patients who were operated for lumbar disc disease in our hospital between 2012 and 2014 were reviewed retrospectively. Twenty one cases of CNR were detected in this series., Results: The mean nerve root thickness was 1.92 ± 0.45 mm for medially located roots and 3.33 ± 0.95 mm for laterally located roots. The comparison of medially located roots versus laterally located roots revealed a significant difference in mean values (p < 0.0001). The mean exit angle was 12.290± 4.890 for medially located roots, and 22.110 ± 5.420 for laterally located roots (p < 0.0001). In addition, the exit angles of the medially and laterally located roots increased as going down to caudal levels, (p=0.005, p=0.042)., Conclusion: CNRs are congenital anomalies that are usually diagnosed during the surgical procedure and affect the success of discectomy. The presence of a more medially located or thinner root during surgical exploration and the absence of the fragment in the axilla in extruded or sequestered discs usually indicate a conjoined nerve root closer to the pedicle.

Background: Chronic urticaria (CU) is a skin disorder defined as daily or almost daily exhibition of pruritic and transient wheals that last for 6 weeks. CU is divided into two subtypes: chronic spontaneous urticaria (CSU) and chronic inducible urticaria (CIndU)., Objectives: To evaluate the clinical features, possible causes, associated findings, and laboratory results of different subtypes of CU in children according to a new classification., Methods: In this study, we evaluated the clinical features, laboratory investigations, and provocation tests of children with different subtypes of CU according to a new classification., Results: Two hundred and twenty-two children (59.9% girls) were enrolled in the study. Of the study patients, 59.9% and 40.1% were diagnosed as having CSU and CIndU, respectively. Antithyroid antibody levels were positive in 7.1% of the patients with CSU, 32.8% of the children had positive 14C-urea breath test results, and 6.5% of the patients had positive stool examination results for parasites. Autologous serum skin test results were positive in 53.5% of the patients with CSU. Of the patients with CIndU, 77.5% had symptomatic dermographism, 16.8% had cold urticaria, 2.2% had cholinergic urticaria, 2.2% had solar urticaria, and 1.1% had aquagenic urticaria., Conclusion: Children with CSU represent the majority of patients with CU, and more than a half of these patients might have autoimmune urticaria. Symptomatic dermographism was the most common type of CIndU.

Idiopathic pulmonary hemosiderosis (IPH) is a rare disorder that should be considered in the differential diagnosis of patients with hemoptysis, recurrent alveolar hemorrhage, dyspnea and iron deficiency anemia (IDA). The frequent association of autoimmune disorders with IPH and a favorable response to steroids suggest the presence of an underlying immune disorder. Here we present a case of a patient with cough, fever, and cyanosis who was also diagnosed with IPH and concurrent selective immunoglobulin A deficiency. This presentation is a unique presentation because of the co-occurrence of these two disorders. Pediatr Pulmonol. 2016;51:E34-E36. © 2016 Wiley Periodicals, Inc., (© 2016 Wiley Periodicals, Inc.)

To dissect the role of immunogenetics in allergy and asthma, we performed a phenome-wide association study in 974 Turkish children selected from a cross-sectional study conducted using ISAAC (International Study of Asthma and Allergies in Children) Phase II tools. We investigated 9 loci involved in different immune functions (ADAM33, ADRB2, CD14, IL13, IL4, IL4R, MS4A2, SERPINE1, and TNF) with respect to 116 traits assessed through blood tests, hypertonic saline challenge tests, questionnaires, and skin prick tests. Multiple associations were observed for ADAM33: rs2280090 was associated with reduced MEF240% (i.e., the ratio of Mean Expiratory Flow after 240s of hypertonic saline inhalation with respect to the age- and ancestry-matched reference value) and with an increased risk of allergic bronchitis (p = 1.77*10(-4) and p = 7.94*10(-4), respectively); rs3918396 was associated with wheezing and eczema comorbidity (p = 3.41*10(-4)). IL4 rs2243250 was associated with increased FEV240 (Forced Expiratory Flow Volume after 240s of hypertonic saline inhalation; p = 4.81*10(-4)) and CD14 rs2569190 was associated with asthma diagnosis (p = 1.36*10(-3)). ADAM33 and IL4 appeared to play a role in the processes linked to allergic airway inflammation and lung function. Due to its association with wheezing and eczema comorbidity, ADAM33 may also be involved in the atopic march.

Immunogenes (i.e., genes related to the immune system and its functions) are involved in the predisposition to numerous traits and their variation contributes to the phenotypic variability observed among human groups. Turkish population presents particular genetic features since its genetic pool is an admixture of European, Middle-Eastern, and Central Asian ancestries. Here, we analyzed the haplotype structure of four immunogenetic loci (i.e., ADAM33; IL13-IL4; IL4R; MS4A2) in 482 subjects from five different regions of Turkey. Genotyping was performed using KASP technology. Turkish data were compared with the haplotype information available from the 1000 Genomes Project Phase 3 (26 human populations from 5 ancestry groups). We did not observe significant differences among Turkish groups. Comparing other ancestries, we identified haplotype similarity of Turkish subjects with European populations in IL13-IL4, IL4R, and ADAM33 loci; and with central Asians in MS4A2 region. Considering loci displaying Turkish-European haplotype similarity (i.e., IL13-IL4, IL4R, and ADAM33), we observed differences between Turkish subjects and northern/western Europeans. Conversely, no significant difference was determined in MS4A2 between Turkish and central Asian populations. Finally, we assessed the haplotypes responsible for the differences between Turkish and European samples and the potential functional effects on the immunogenetic loci investigated., (Copyright © 2016 Elsevier B.V.

Background: Skin testing has a limited role in the diagnosis of non-immediate beta-lactam hypersensitivity in children. The aim of this study was to report the results of oral provocation tests performed without skin tests in children with non-immediate mild cutaneous reactions without systemic symptoms caused by beta-lactam antibiotics., Methods: Oral provocation tests with suspected antibiotics were performed to patients with non-immediate mild cutaneous reactions without systemic symptoms caused by beta-lactam antibiotics. Skin tests were not performed before provocation tests. A total of five doses were administered with half-an-hour intervals in increasing doses. Provocation was continued for 5 days., Results: A total of 119 patients with a median age of 4.3 (IQR: 2-7.5) years, of whom 58% were males, were included in the study. Amoxicillin-clavulanic acid was the most frequently responsible agent in 87 (73.1%) patients, and most common type of rash was maculopapular in 74 (62.2%) patients. Four patients (3.4%) had an urticarial reaction during the provocation test., Conclusion: We did not experience any severe reactions during oral provocation test without previous skin tests performed to children with non-immediate mild cutaneous reactions without systemic symptoms. Omitting skin tests before oral provocation test in this group of children can help decreasing the burden of allergy clinics and alleviating the discomfort of children., (© 2015 John Wiley & Sons A/S.

Aim: Surgical anatomy concerning the posterior craniovertebral region in fresh human cadavers was studied to provide most accurate information for the surgical approach., Material and Methods: In thirty-two fresh human cadavers, the distance from the posterior tubercle to the sulcus of vertebral artery (VA), the thickness and length of the third segment of VA (V3), the distance of C1/C2 facet to V3, the length, height and shape of the C2 ganglion to the neighboring structures, the distance from medial border of C1 lateral mass to dura mater, the distance of the transverse process of atlas to mastoid tip, the thickness of C1 posterior arcus were measured., Results: There were variations of sulcus of VA in 14 of 32 cadavers (43.7%), the right VA was larger in 23 cadavers (71.8%). The ganglion was found over the C1 lateral mass screw entry point in 45 of 64 ganglions (70.31%) and below the screw entry point in 19 of 64 ganglions (29.69%). The distance of the medial border of the C1 lateral mass to dural tube was 3.81±0.55 mm at the right side and 3.91±0.59 mm at the left. The thickness of C1 posterior arch was 3.73±0.75 mm at the right side and 3.75±0.77 mm at the left. The mean distance from the transverse process of C1 to the mastoid tip was 15.82±4.49 mm at the right side and 15.46±4.38 mm at the left., Conclusion: This is the most comprehensive and only fresh cadaver study about this region in the literature.

Enzyme replacement therapy (ERT) is important for the treatment of lysosomal storage disorders. Hypersensitivity reactions with ERT have been reported, and in these cases, desensitisation with the enzyme is necessary. Here we report the cases of 3 patients with lysosomal storage disorders, including Pompe disease and mucopolysaccharidosis type I and VI, who had IgE-mediated hypersensitivity reactions and positive skin tests. Successful desensitisation protocols with the culprit enzyme solution were used for these patients. All 3 patients were able to safely receive ERT with the desensitisation protocol., (© 2016 S.

Objective: To address the problems about correct use of inhaler devices, adherence to inhaler corticosteroid treatment and the effects of these problems on the control of asthma., Methods: Children with asthma were evaluated for the correct use of inhaler devices and adherence to therapy using a questionnaire. Effect of these on control of asthma was defined., Results: A hundred and seventy-one patients and/or their families were interviewed. The mean age was 8.29 ± 4.65 years (1-19) and 62.6% were male. Metered dose inhaler (MDI) with spacer was used by 119 (69.5%) patients and 52 (30.5%) used dry powder inhalers (DPIs). The devices were used correctly by 68.1% of patients using MDI and 34.6% of patients using DPI (p < 0.001). The most common improper step was "breathe in from the spacer 5-6 times or 10 s" for MDI (24.4%) and "exhale to residual volume" for DPI (51.9%). Frequency of correct use was higher in patients trained 3 times (p < 0.001). Asthma was controlled more frequently among correct users (p < 0.001). Partial or poor adherence was showed 22.8% of patients. Patients with mothers who had lower educational status had higher frequency of incorrect use of inhaler device (p = 0.007)., Conclusion: It was found that asthma control was better among correct users. Repetitive training about using devices may contribute improving inhaler technique. Especially children whose mothers had low education level and patients using DPI should be evaluated more carefully.

Background: Nonsteroidal anti-inflammatory drugs (NSAID) are the second-most frequent drugs that cause hypersensitivity reactions among children. Studies related to NSAIDs hypersensitivity in children are limited. In this study, we aimed to evaluate children admitted with suspicion of NSAIDs reaction., Method: Between January 1, 2011, and November 30, 2014, we included patients with suspicion of NSAIDs hypersensitivity in our clinic. For evaluation, skin tests and oral provocation tests with the drug (suspected or alternative) were proposed. Reactions were classified and defined according to the latest European Academy of Allergy and Clinical Immunology position paper on NSAID hypersensitivity., Results: During the study period, 123 patients (with 136 drug reactions) were admitted to our clinic with suspected NSAID hypersensitivity. The mean (standard deviation) age of the patients, 67 female (55%), was 83.10 ± 56.05 months. Thirteen patients described reactions to more than one chemically unrelated NSAID, and 110 patients described reactions with chemically similar drugs. Eight patients were not included because they did not have provocation tests. Thus, 115 patients were evaluated. A hundred and thirty provocations were performed. Twenty patients (17.4%) were diagnosed with NSAID hypersensitivity (13 patients diagnosed by provocation tests and 7 patients diagnosed according to their history). The most frequently encountered agent was ibuprofen (50% [10/20]). Eighty percent (16 patients) of the reactions were considered "non-cross-reactive type." Fifteen patients (75%) were classified as having single-NSAID-induced urticaria and/or angioedema, three patients were classified as having NSAID-induced urticaria and/or angioedema, one patient was classified as having NSAID-exacerbated respiratory disease, and the other patients were classified as having single-NSAID-induced delayed hypersensitivity reactions., Conclusion: Detailed history and drug provocation tests are important to verify NSAID hypersensitivity. The most common type is the non-cross-reactive type, and, in our study, the most common responsible drug was ibuprofen.

Objectives: The dietary protein proctocolitis, also known as allergic proctocolitis (AP), is characterized by the presence of mucoid, frothy, and bloody stools in an otherwise healthy infant. The aim of this study was to describe a group of children with AP, diagnosed according to the criterion-standard method, food challenge to provide clinicians with more information on typical presentation, and an overview on nutritional management strategies and prognosis., Methods: We collected data on infants with AP in our allergy and gastroenterology outpatient clinics. Any other conditions that may cause bloody diarrhea were ruled out. Skin prick tests and atopy patch tests were performed for diagnosis, and patients were studied for resolution. To the patients whose rectal bleeding did not recover with oligoantigenic maternal diet in addition to amino acid-based formula, endoscopic evaluation was performed to confirm the diagnosis and to exclude other reasons of rectal bleeding., Results: Sixty patients were diagnosed as having AP. The age of onset was 1.7 ± 1.32 months. All of the patients were triggered by milk, 6.6% with milk and egg, 3.3% with milk and chicken, 1.7% with milk and wheat, 1.7% with milk and potato, and 3.3% had multiple food allergy. 53.3% (n = 32) acquired tolerance by age 1, 25.0% (n = 15) by 2 years, 5% (n = 3) by 3, and 1.7% (n = 1) by 4 years., Conclusions: Milk was a triggering factor for all of the patients. Resolution of AP is usually within 1 year but symptoms of some patients may continue even longer. An extension of the follow-up period is required according to our study.

Background/aim: Data about contact allergen sensitization (CAS) in children with atopic dermatitis (AD) are limited. The purpose of this study was to identify the frequency and patterns of CAS in children with AD by using a ready-to-use patch test system., Materials and Methods: After receiving the history of CAS in the patients, the severity of AD and IgE-mediated allergen sensitization were determined., Results: Of 134 children with AD, 33.8% (n = 45) had at least 1 positive reaction. The most frequent positive reaction was to nickel sulfate (NS) (37.8%, 17/45), followed by methylchloroisothiazolinone (20.0%, 9/45) and thimerosal (15.6%, 7/45). The total Scoring Atopic Dermatitis (SCORAD) score was significantly higher in the NS-sensitized group (P = 0.036). The patients with NS sensitization had moderate-severe AD more frequently than those without any reaction (P = 0.020). When the SCORAD score was evaluated in detail, extent of eczema, score of sleep loss, and pruritus were significantly higher in the patients with NS sensitization than those without any reaction (P = 0.002, P = 0.001, and P = 0.002, respectively)., Conclusion: Our study confirms the necessity of CAS in the management of AD. In particular, NS sensitization should be considered for children with severe AD or larger extent of eczema and trunk involvement.

Background: The negative predictive value of the drug provocation test is important for both the patient and the physician. However, in children, this predictive value is unresolved., Methods: The study included patients who had drug provocation test with a suspected drug and was diagnosed as 'not allergic to the drug'. Three months after allergy workup, the patients were contacted and asked for reexposure to the tested drug. Patients who have reported reactions during reexposure were reevaluated with skin tests and drug provocation., Results: During the study period, 217 provocations were performed to 203 patients. Of these, 163 patients (80.3%) with 175 negative drug provocation tests could be contacted. Ninety-one (52%) of the 175 cases reported to use the tested drug again, and 11 (12%) of these cases declared that they had a new reaction. Two of the eleven cases refused reevaluation. Nine cases were evaluated by drug allergy workup. Two of the nine cases were classified as allergic after retests. Collectively, the negative predictive value was 95.6% (87 of 91 cases) for all drug challenges., Conclusions: The negative predictive value of the drug provocation test is abundant in children; however, negative drug provocation tests do not necessarily predict tolerance for the drug., (© 2014 John Wiley & Sons A/S.

Background: In this study, our goal is to evaluate the consistency between TRACK and the asthma control levels assessed according to the GINA and NAEPP guidelines in children younger than 5 years of age., Methods: Patients under 5 years old, who were followed up for recurrent wheezing for at least 1 year have been included. Parents were given the TRACK questionnaire and the control level of asthma according to GINA and NAEPP guidelines were determined by a pediatric allergist blinded to TRACK scores. Patients were classified into two groups regarding the compatibility of the control level between TRACK and both GINA and NAEPP guidelines., Results: A total of 365 questionnaires were evaluated. The TRACK cut-off point of 80 provided the most consistent balance between sensitivity and specificity for the compatibility with both GINA and NAEPP (for GINA 0.763 and 0.663, kappa = 0.487, p < 0.001 and for NAEPP 0.761 and 0.769, kappa = 0.524, p < 0.001, respectively). When 80 was taken as the cut-off value for TRACK, the compatibility rate of asthma control levels between TRACK and GINA and TRACK and NAEPP was 71.0 and 76.4%, respectively. About 70.1% of the patients who had TRACK scores over 80 and had mild asthma were grouped as controlled according to GINA and 50.0% of patients who had TRACK scores over 80 and had moderate to severe asthma was grouped as uncontrolled according to GINA (p = 0.019)., Conclusion: TRACK is compatible with NAEPP and GINA in majority of asthmatic children under 5 years of age. Nevertheless, there is a discrepancy between guidelines and TRACK scores; therefore, it should be used in conjunction with a detailed clinical examination in order to make a better decision for assessing the control levels and management plan.

Objectives: Results of previous studies have established several factors related with the natural course of childhood asthma. The aim of this study is to investigate the prognosis of childhood asthma and to determine possible risk factors for disease persistence., Methods: An outpatient cohort with a median (interquartile range) follow-up duration of 19.4 (17.7-21.8) years was re-evaluated. Current clinical remission (CR) was defined as no asthma symptoms and no use of controller medication within the past year., Results: Out of 115 patients, 78 could be surveyed with questionnaire and 46 patients with a median age of 25.3 (23.9-27.0) years were further investigated with clinical work-up. Nineteen (24.4%) patients were in CR in both visits (adolescence and young adulthood). A further 7 patients (9.0%) who were not in CR at adolescence were in CR at the young adulthood visit. However, 21 patients (26.9%) who were in CR at adolescence were not in CR at the young adulthood visit. Thirty-one patients (39.7%) with persistent symptoms at adolescence were not in CR at young adulthood, either. In multivariate logistic models, the presence of obstructive pattern (forced expiratory volume in 1s (FEV1)/forced vital capacity (FVC) <80% vs. ≥80%) in pulmonary function tests during the adolescence period (odds ratio; [95% confidence interval] (6.71 [1.65-27.29]; p=0.008) and later-onset rhinitis (10.27 [1.18-89.13]; p=0.035) predicted the absence of CR at young adulthood., Conclusion: A substantial number of patients who were in CR during adolescence have re-emerging disease. The presence of obstructive pattern in adolescence and later-onset rhinitis were associated with the absence of CR in young adults with asthma. Awareness of risk factors along with early interventions may provide better results in childhood asthma., (Copyright © 2014 Elsevier Ireland Ltd. All rights reserved.)

Study Design: Analysis of the adjacent-segment fractures in 171 balloon kyphoplasty (BK)-performed patients., Objective: The purpose of this study was to investigate the risk factors for new symptomatic vertebral compression fractures (VCF) after BK., Summary of Background Data: Although there are many studies about the incidence and possible risk factors for occurrence of adjacent-level fractures, there is no consensus on the increased risk of adjacent-level fractures after BK., Methods: We performed a retrospective analysis of 171 patients treated with percutaneous kyphoplasty. The follow-up period was 41.04±21.78 months. The occurrence of new symptomatic VCF was recorded after the procedure. We evaluated the variables of patient age and sex, the amount of injected cement, the initial kyphotic angle (KA) of VCF, the change of the KA after BK, the severity of osteoporosis, and the percentage of height restoration of the vertebral body. Furthermore, possible risk factors were reported for new symptomatic VCFs., Results: The only 2 factors identified as being significantly associated with adjacent-level fractures were the sex (P=0.001) of the patient and the preoperative KA (P=0.013). The patients with new symptomatic compression fracture had higher initial KA than those without fractures. The female group had higher risk than the male group in occurrence of the new vertebra fractures. The severity of the osteoporosis (low bone mineral density) was not a determinant in occurrence of the new VCF after BK., Conclusions: If the patients experience severe or mild back pain with higher preoperative KA, especially in the first 2 months, then they deserve detailed radiologic examination. To avoid subsequent fracture in the same or adjacent level, vertebral body should be filled adequately and sagittal balance should be obtained with KA correction. BK alone did not influence the incidence of subsequent VCF.

Drug provocation tests (DPTs) are gold standard to diagnose drug allergy. Our goal was to evaluate the results and safety of diagnostic methods including DPTs during childhood. Between January 2010 and February 2013 DPTs were performed and evaluated, prospectively, in children who attended our pediatric allergy clinic with a suspected drug hypersensitivity reaction. One hundred ninety-eight suspected drug reactions in 175 patients (88 boys and 87 girls) were evaluated. The median age of the subjects at the time of the suspected drug-induced hypersensitivity reaction and at the time of the study was 56 (interquartile range [IQR] = 24-120 months) months and 76 (IQR = 35-149 months) months, respectively. Suspected drugs were beta-lactam antibiotics in 108 cases (54.5%), non-beta-lactam antibiotics in 22 cases (11.1%), and nonsteroid anti-inflammatory drugs in 52 cases (26.3%). The history was compatible with immediate-type reactions in 69 cases (34.8%). Skin-prick tests were not positive in any of the cases. Intradermal tests were positive in three cases (4%). DPTs were positive in 13 (6.8%) of 191 provocation cases, which were performed with culprit drugs. Our results suggest that a positive clinical history is not enough to make a diagnosis of drug allergy, which highlights the significance of undertaking further diagnostic evaluation especially for DPTs.

Objectives: The objectives of this study were to test the effects of the new combination treatment modality, sorafenib (SOR) and lithium chloride (LiCl) and to assess whether midkine (MK) protein has a role in any potential effects., Methods: Monolayer and spheroid cultures of T98G human glioblastoma multiforme (GBM) cells were treated with LiCl and SOR (inhibition concentration 50 value  =  100 μM), or their combination, or were left untreated (control). Cell proliferation and apoptotic indices, the mechanism of action, and the levels of apoptotic and anti-apoptotic proteins were evaluated in monolayer cultures and ultrastructure was evaluated by transmission electron microscopy (TEM) in spheroid cultures after for 72 hours., Results: All drug applications decreased cell numbers and increased the apoptotic index. The combination shows a synergistic effect. In the combination group, the decrease in cell numbers and the increase in the apoptotic index were significantly greater than with the individual drugs (P < 0.01). The combination treatment led to the greatest decreases in MRP-1 and p170 levels; but the greatest decreases in p-STAT-3, p-ERK (P < 0.05), p-AKT, p-GSK-3-beta (P < 0.01), EGFR (P < 0.01), NF-kappa-β levels were with SOR alone, followed by the combination. The decreases in MK levels in the SOR and combination groups were similar (P  =  0.06). Severe ultrastructural damage was more frequently observed in the combination group compared with the other groups., Conclusions: These results suggest the possibility that the addition of LiCl to SOR could improve the prognosis in at least some patients who need both cancer and psychotherapy and indicate the need for further studies.

The aim of this study was to evaluate the risk factors of disease severity to facilitate better management of children with severe atopic dermatitis (AD). All the patients were diagnosed using Hanifin-Rajka criteria. After medical and family histories were obtained and a detailed physical examination was performed, disease severity was determined with the objective SCORing Atopic Dermatitis (SCORAD) index. Skin prick tests were performed, and percent of peripheral blood eosinophils, total serum IgE and specific IgE were measured. The median age of the 501 patients was 15 months (interquartile range [IQR]: 6-40 months), and 62.9% (315) were male. Sensitization to at least one allergen and foods was observed in 40.3% (202) and 30.9% (155) of all patients, respectively. Of the study group, 17.6% (88) had severe disease. When logistic regression analyses were performed, with adjustments, the risk factors for severe AD were determined to be eosinophilia (odds ratio [OR] 1.137, 95% confidence interval [CI] 1.062-1.217; p=0.003) and food allergen sensitization (OR: 1.937, 95%CI: 1.217-3.084; p=0.005). The patients with severe AD had sensitization to common allergens, food allergens and eosinophilia more frequently than those with mild-moderate disease (p=0.001, p=0.001 and p=0.005, respectively). Eosinophilia may predict severe disease and allergic sensitization. Further large-scale follow-up studies are needed to improve the reliability and relevance of this relation.

Aim: This study was aimed to investigate the variations in the spinal nerve root compositions of musculocutaneous nerve and to confirm which spinal nerve root is the main ingredient in participating amount., Material and Methods: A total of 20 fresh cadavers were dissected. Brachial plexus and its branches were extracted. Musculocutaneous nerve stump was traced back to the roots to identify its fascicular origin. The number of fascicles originating from a particular nerve root and their axial location with in the nerve were noted., Results: The most frequent type of spinal nerve compositions of musculocutaneous nerve was C5, C6, and C7 with incidence of 60%. Musculocutaneous nerve had bundles from C5 root in all specimens, 90% of the specimens had contribution from C6 and only 70% of them had bundles from C7 root. There were a total of 46 (37.7%) bundles in C5 fascicles, 48 (39.3%) bundles in C6 fascicles, and 28 (22.9%) bundles in C7 fascicles., Conclusions: In electrophysiological studies it should be remembered that C7 or C6 lesions may not impair musculocutaneous nerve functions. The success of musculocutaneous nerve neurotization may be improved if care is taken to ensure whether or not C7 root is contributing to the musculocutaneous nerve.

Atopic dermatitis (AD) and hypogammaglobulinemia are 2 entities that appear during early childhood. Some studies report that atopy and atopic diseases are frequent among children with low immunoglobulin [Ig] levels. The aim of the study was to define the characteristics of children with both AD and low serum Ig levels. One hundred and twenty-five AD patients under 4 years of age who had low serum Ig levels were compared with their peers with normal Ig levels, in terms of age, gender, parental consanguinity, exposure to smoke, breastfeeding, personal and familial atopy, IgE level, peripheral eosinophil content, and disease severity. Consanguinity of parents and other allergic diseases were more common among children with normal Ig levels. Serum IgE levels were lower among patients with low Ig levels. Disease severity was not different between the groups. When low for age, serum IgA and IgM levels are related to the severity of AD. Hypogammaglobulinemia can coexist with AD in young children. The level of Ig deficiency may affect AD severity. Larger prospective studies are needed for better understanding the effect of hypogammaglobulinemia on AD and for developing better management strategies for patients who have both conditions together.

Background: Although food allergy is an important health problem in Western countries, the prevalence varies among geographic regions. There is limited data on the prevalence of food allergy especially for adolescent age group, and the data from Turkey and Mediterranean region are even scarce., Methods: The study is a cross-sectional survey including a questionnaire followed by phone survey with families that have reported food allergy and clinical evaluation of children having a history compatible with food allergy after phone survey. The sample number of students has been calculated 9096 of a total of 210.000 students at the second stage (6th, 7th, and 8th grades) of state elementary schools in the metropolitan counties of Ankara province with the assumption of food allergy prevalence (P) = 1% and a δ value = 0.2 (α < 0.05, β = 0.8)., Results: Of 11,233 questionnaires distributed at 34 schools, 10,096 (89.4%) have been returned. The number of reported food allergy was 1139 (11.2%), and it was reduced to 133 (1.3%) after phone survey. After clinical evaluation by skin test, specific IgE and double-blind placebo-controlled food challenge (DBPCFC), proven IgE-mediated food allergy was determined in 15 (0.15%) children. The foods most commonly resulting food allergy were peanut 0.05% and treenuts 0.05%., Conclusion: The prevalence of food allergy among adolescent age group has been confirmed to be comparatively low in Turkey. Peanuts and treenuts were determined to be the most common causes of IgE-mediated food allergy., (© 2013 John Wiley & Sons A/S. Published by John Wiley & Sons Ltd.)

Anaphylaxis is a potentially life-threatening condition. There are limited data about the etiology and the clinical characteristics in developing countries. This study aimed to investigate the clinical characteristics of anaphylaxis patients attending our pediatric allergy clinic. We conducted a prospective analysis of patients who were admitted to our allergy clinic for anaphylaxis from 2010 to 2012. Ninety-six patients were evaluated during the study period. The mean age was 7.4 ± 5.2 years. Venom, food, and drugs were the most common causative agents responsible for 31 (32.3%), 30 (31.3%), and 26 (27.1%) of the cases, respectively. Foods implicated most frequently were peanuts and nuts (n = 9; 30.0%), cow's milk (n = 7; 23.3%), and egg white (n = 6; 20.0%). The clinical manifestations during anaphylaxis in order of frequency were cutaneous (97.9%), respiratory (86.5%), gastrointestinal (42.7%), neurological (37.5%), and cardiovascular symptoms (30.2%). A biphasic course was noticed in five cases (5.2%). Of the 91 patients, 79 (86.8%) received H1-antihistamines, 73 (80.2%) received corticosteroids, 40 (44.4%) received adrenaline, 38 (41.8%) received fluid replacement therapy, 18 (19.8%) received β2-mimetics, and 8 (8.8%) received H2-antihistamines. According to severity, 7.3% of patients had mild, 59.4% had moderate, and 33.3% had severe anaphylaxis. Food and bee venom allergy were the most common etiologies. Adrenaline, the first-line treatment of anaphylaxis, was administered in only 44.4% of our cases.

Background: Acute asthma is one of the most common medical emergencies in children. Appropriate assessment/treatment and early identification of factors that predict hospitalization are critical for the effective utilization of emergency services., Objective: To identify risk factors that predict hospitalization and to compare the concordance of the Modified Pulmonary Index Score (MPIS) with the Global Initiative for Asthma (GINA) guideline criteria in terms of attack severity., Methods: The study population was composed of children aged 5-18 years who presented to the Emergency Departments (ED) of the tertiary reference centers of the country within a period of 3 months. Patients were evaluated at the initial presentation and the 1(st) and 4(th) hours., Results: Of the 304 patients (median age: 8.0 years [interquartile range: 6.5-9.7]), 51.3% and 19.4% required oral corticosteroids (OCS) and hospitalization, respectively. Attack severity and MPIS were found as predicting factors for hospitalization, but none of the demographic characteristics collected predicted OCS use or hospitalization. Hospitalization status at the 1(st) hour with moderate/severe attack severity showed a sensitivity of 44.1%, specificity of 82.9%, positive predictive value of 38.2%, and negative predictive value of 86.0%; for MPIS ≥ 5, these values were 42.4%, 85.3%, 41.0%, and 86.0%, respectively. Concordance in prediction of hospitalization between the MPIS and the GINA guideline was found to be moderate at the 1(st) hour (κ = 0.577)., Conclusion: Attack severity is a predictive factor for hospitalization in children with acute asthma. Determining attack severity with MPIS and a cut-off value ≥ 5 at the 1(st) hour may help physicians in EDs. Having fewer variables and the ability to calculate a numeric value with MPIS makes it an easy and useful tool in clinical practice., (Copyright © 2013 Elsevier Inc. All rights reserved.)

Background: Despite drug-related hypersensitivity reactions are an important health problem, epidemiologic data on drug allergy and hypersensitivity are limited, and studies including diagnostic work-up are scarce. The aim of this study was to determine the actual frequency of immediate type drug hypersensitivity using diagnostic tests in school children with parent-reported drug allergies., Methods: This study involved three phases. The first phase is a survey of children with a mean age of 12.9 yrs attending grades 6-8 of primary schools with a questionnaire asking drug-related symptoms within 2 h of ingestion. The total population of sixth to eight grade school children was 210,000, and a sample size of 9096 was deemed to be representative of Ankara [(p) = 1.0%, α < 0.05, β = 0.8, (d) = 0.2.] During the second phase, a detailed clinical history was obtained by phone from the parents of children who had positive parent-reported drug allergy. The final stage of the study consisted of a detailed diagnostic work-up of children with a clinical history consistent with immediate type drug hypersensitivity reaction., Results: Overall, 11,233 questionnaires were distributed, 10,096 of which were retrieved after completion by parents. The rate of parent-reported immediate type drug hypersensitivity was 7.87% (792 children). However, phone survey revealed a clinical history suggestive of drug allergy in only 117 children (1.16%). After further diagnostic work-up, the true frequency of immediate type drug hypersensitivity was 0.11%., Conclusion: Our results suggest that a positive clinical history is not enough to make a diagnosis of drug allergy, which highlights the significance of undertaking further diagnostic evaluation., (© 2013 John Wiley & Sons A/S.
