(Wiley, 2002-03-11) Sapan, Nihat; Canitez, Yakup; Sağlam, Halil; Nacarküçük, Ergün; Uludağ Üniversitesi/Tıp Fakültesi/Pediatri Anabilim Dalı.; 0000-0003-0710-5422; C-7392-2019; 6602156485; 6602924559; 8988954700; 35612700100
Background: Recently, there was a great increase in allergic reactions to latex and this brought relatively more concern to the latex allergy. In this prospective study we aimed to identify the frequency of latex allergy in preoperative patients, and tried to clarify whether it is necessary to perform latex allergy tests routinely in the preoperative period or not. Methods: A total of 188 children, aged 1-14, who were admitted for various operations, were randomly included in this study and of them, 181 completed the study. Latex specific history was taken from all patients. Latex skin prick tests, challenge tests with latex gloves, total IgE and latex specific IgE measurements were performed. Results: Of 181 children, two (1.1%) had positive latex skin prick tests. Latex challenge tests were negative in all children. Latex specific IgE was positive in 12 children (6.6%) as class II or higher, but no patient had allergic reactions in operations. History of repeated operations was a risk factor for latex sensitization. The risk was higher in the presence of both history of repeated operations and history of allergic disease. However, the risk was not higher in patients with the history of only allergic disease, compared to ones who had a history of neither repeated operations nor allergic disease. Conclusion: We conclude that routine preoperative latex allergy tests seem to be not necessary because of no allergic reactions during operation in spite of the sensitization of 6.6% detected by latex specific IgE. However, this should be investigated in larger studies.

(Galenos Yayincilik, 2013-12-01) Canitez, Yakup; ÇEKİÇ, ŞÜKRÜ; CANITEZ, YAKUP; GÜRPINAR, ARİF NURİ; Gürpınar, Arif; Sapan, Nihat; SAPAN, NİHAT; Bursa Uludağ Üniversitesi/Tıp Fakültesi/Çocuk Sağlığı ve Hastalıkları Anabilim Dalı.; 0000-0002-9574-1842; L-1933-2017
Right lung agenesis is a rare anomaly that can be isolated or accompanied by system anomalies such as cardiac, skeletal or urinary systems. Case 1, a four-month-old girl, was brought because of respiratory distress. Patient had polydactyly, syndactyly of right thumb, right mandibular hypoplasia and low-set dysmorphic ears. Lung x-ray and thorax computerized tomography (CT) were consistent with right pulmonary agenesis and butterfly vertebra was evident in the 7th thoracic level. Thoracic CT angiography revealed narrowing of the left main bronchus and esophagus due to compression of aorta, left pulmonary artery and right atrium. In bronchoscopy, narrowing due to compression at the carina level was seen and right main bronchus was not seen. In abdominal ultrasonography, right kidney placement anomaly (pelvic ectopia) was present and renal scintigraphy revealed fusion in both kidneys. With these findings, it was found that right pulmonary agenesis was accompanied by ipsilateral radial ray anomaly, renal anomaly, vertebral anomaly and hemifacial microsomia. Case 2, a fifteen-year-old male patient, was diagnosed as pulmonary agenesis via chest x-ray, pulmonary CT and bronchoscopy after a wheezing episode when he was 2 months old. Patient had no complaint except for exhaustion that is aggravated by exercise during last year. In physical examination, he had a mild scoliosis toward right, respiratory sounds were diminished on right hemithorax and heart sounds were heard on right side. Chest x-ray and thoracic CT were consistent with right lung agenesis. No abnormality was found in echocardiography and abdominal ultrasonography was normal. Accompanied cardiovascular anomalies, distortions of intrathoracic structures and recurrent infections are main factors that affect mortality and morbidity. Here, two cases with right lung agenesis, isolated and accompanied by multiple anomalies, were presented.

Aim: The aim of this study was to consider clinical features, laboratory findings, treatment alternatives, complications and responsible agents of Steven's Johnson Syndrome (SJS) and Toxic Epidermal Necrolysis (TEN) in childhood.Materials and Method: The patients who were diagnosed with Steven's Johnson syndrome (SJS) or Toxic Epidermal Necrolysis (TEN) and followed by Department of Dermatology, Division of Pediatric Neurology and Division of Pediatric Allergy of Uludag University Faculty of Medicine, between 2000-2008 were evaluated retrospectively.Results: Records of 14 patients (7 females/7 males) were examined, Nine of the patients had SJS, 2 had SJS-TEN overlap syndrome and the rest 3 had TEN. Nine patients had history of using drugs for epilepsy and the others for anxiety, tooth abscess, cryptic tonsillitis, otitis media and bronchiolitis, Eleven of the patients (78.5%) had multiple drug intake. In 7 patients (50%) Lamotrigine (4 of 7 patients was also taken Valproic acid) and in other patients oxcarbamazepine, azytromicine, phenytoin, imipra mine, cefuroxime axetil, ciprofloxacin, ceftriaxone were responsible for SJS and TEN. Twelve 13atients were treated with systemic corticosteroid and 2 vvith intravenous All of the patierits vvere cured.Conclosion: Although drug reactions were seen less frequently ill childreri coniipared to adults,. it nitist be taken.. into ci3risideration that there is the risk i3f developing severe drug reactions like SJS and TEN in children who have been using such drugs for a long time or using multipl drugs for extended periods.
The evaluation of local and systemic reactions to subcutaneous house dust mite allergen immunotherapy
(Galenos Publ House, 2022-06-15) Canitez, Yakup; CANITEZ, YAKUP; Karali, Zuhal; KARALI, ZUHAL; ÇEKİÇ, ŞÜKRÜ; SAPAN, NİHAT; Şadırvan, Yağmur Hazal; ŞADIRVAN OĞUZKAYA, YAĞMUR HAZAL; Bursa Uludağ Üniversitesi/Tıp Fakültesi/Pediatri Anabilim Dalı.; L-1933-2017
Objective: Allergen -specific immunotherapy is an effective treatment method that enables the development of immunotolerance against allergens in allergic rhinitis, asthma, and venom allergy. This study investigated the local and systemic reactions during subcutaneous house dust mite allergen immunotherapy. Methods: Injection -related local and systemic reactions of 45 patients who received subcutaneous mite immunotherapy were evaluated retrospectively. Results: Forty-five children, 15 (33.3%) females and 30 (66.4%) male were included in the study. A total of 582 injections were administered. A local reaction was observed in 23 (3.94%) of all injections and the systemic reaction was observed in only 1 (0.17%) injection. Sixteen (37.7%) of the children had local reactions during the immunotherapy process and 1 (2.2%) had a systemic reaction. Conclusion: Although subcutaneous mite immunotherapy is a safe treatment, it should only be applied in centers with appropriate emergency equipment and trained healthcare professionals due to possible systemic reactions.
