Item Septic pulmonary emboli presenting with deep venous thrombosis secondary to acute osteomyelitis(2004) Yüksel H.; Özgüven A.A.; Akil I.; Ergüder I.; Yilmaz D.; Çabuk M.[No abstract available]Item Borderline phyllodes tumor of the breast in an adolescent girl; [Adölesan kiz olguda memenin "Borderline" fillodes tümörü Olgu Sunumu](2008) Genç A.; Yilmaz Ö.; Özgüven A.A.; Ersoy B.; Aygören R.; Kandiloǧlu A.R.; Taneli C.Phyllodes tumor (PT) is a tumor similar to fibroadenoma, that can reach to enormous sizes. It consistic less than 1 % of all breast neoplasms. Here, a 13 years old female patient is reported due to its rarity. She presented with a mass in the right breast which showed hard consistency and fixation to the thoracic wall by palpation and caused retraction of the nipple. Tomography revealed a solid mass with the diameter of approximately 11 cm. Patient was operated with the presumptive diagnosis of PT or breast carcinoma and the mass was totally excised together with its capsule. Pathologic examination showed 6 mitotic cells in each field, medium cellularity and slight atypia. It was accepted as a borderline tumor but no recurrence or metastasis was observed within postoperative 5 months. As for conclusion, PT should be considered in rapidly expanding masses of breast that present with enormous size.Item Successful use of inhaled steroids for the management of radiation pneumonitis in an infant: Case repot; [Radyasyon pnömonisinin tedavisinde i̇nhale steroidlerin bir süt çocuǧunda başarı ile kullanımı](Turkiye Klinikleri, 2010) Mutafoǧlu Uysal K.; Uzuner N.; Çetingöz R.; Özgüven A.A.; Babayiǧit A.; Ölmez D.; Güneş D.; Olgun N.Radiation pneumonitis and subsequent pulmonary fibrosis are among the serious complications of thoracic irradiation and can have severe implications on patients' quality of life. Systemic corticosteroids are commonly used agents to treat radiation pneumonitis. However, the potential adverse effects of systemic corticosteroids, particularly in growing children, are consid-erable. An infant with lung metastatic Ewing sarcoma developed severe radiation pneumonitis following chemoradiotherapy. Systemic prednisolone was started first. However, due to the prolonged need for corticosteroid therapy, inhaled budesonide was administered with reduced systemic corticosteroid dose in an attempt to avoid the adverse effects of systemic corticosteroid treatment. The treatment was then continued exclusively with budesonide with a good clinical response. To our knowledge, this is the first pediatric case reported to benefit from inhaled steroids for severe radiation pneumonitis. This response suggested that inhaled steroids might serve as a adjunct or even an alternative to systemic corticosteroids in radiation pneumonitis. © 2010 by Türkiye Klinikleri.Item Evaluation of nutritional status in Turkish adolescents as related to gender and socioeconomic status(2010) Özgüven I.; Ersoy B.; Özgüven A.A.; Erbay P.D.Objective: To evaluate the nutritional status of Turkish high school adolescents using anthropometric indicators and to determine the relationship of nutritional status with gender and socioeconomic status (SES) in adolescents. Methods: Six hundred eighty adolescent students (n=284 males, 396 females) aged 14-18 years were selected from 6 high schools of different regions. Nutritional status was evaluated according to the anthropometric indicators, which were based on the WHO criteria. Adolescents were grouped into three SES categories. Results: The rates of being stunted, underweight, and overweigh/obesity were 4.4%, 5.0% and 16.8%, respectively. Height and weight standard deviation scores (SDS) were significantly lower in adolescents with low SES (p<0.05). The frequency of stunting was significantly higher in adolescents with low SES (p=0.012). Frequency of underweight, overweight and obesity did not differ significantly between socioeconomic groups and genders (p>0.05). Conclusion: Adolescents of low SES were shorter and thinner than those of other SES categories. Undernutrition needs to be addressed in low SES. Among all Turkish adolescents, the major nutritional problems were overweight and obesity. There were no SES and gender differences in prevalence of overweight and obesity among the Turkish school adolescents living in urban areas. Prevalence of obesity is rising, regardless of differences in SES and gender, in developing countries too. © Journal of Clinical Research in Pediatric Endocrinology.Item A child with cervical Castleman's disease mimicking nasofaringeal carcinoma: Case report; [Nazofarenks karsinomunu taklit eden servikal Castleman hastaliǧi tanili bir çocuk olgu](2010) Neşe N.; Özgüven A.A.; Onaǧ A.; Yücetürk A.V.Castleman's disease (CD) is an uncommon benign disease that causes progressive lymph node enlargement. Most observations of CD have focused on adult patients and it rarely occurs in children. It usually arises as a solitary mass and is commonly found in the mediastinum and abdomen and less commonly in the head, neck and axilla.The diagnosis of CD is histopathological. We report a child of CD in the neck region who also had a mass at the nasopharenx mimicking nasofaringeal carcinoma and review the published child cases with CD that involved neck region. This report emphasizes that CD should be considered in the differential diagnosis of children presented with neck mass.

Lymphoma, malignant melanoma, and rhabdomyosarcoma are the most common tumors that metastasize into breast tissue. The histological spectrum of breast masses in children and adolescents is different from that of adults. Imaging findings are useful for performing a diagnosis, but in a patient with a known malignancy, any enlarging breast mass, even one with a benign radiological appearance, should be investigated with a biopsy. In this article, we present the imaging findings of a 12-year-old female patient with breast metastasis of Ewing's sarcoma. © Turkish Society of Radiology 2012.Item Wernicke's encephalopathy in a child with Down syndrome, undergoing treatment for acute lymphoblastic leukemia(Blackwell Publishing, 2016) Yıldırım A.T.; Bilgili G.; Akman B.; Ovalı G.Y.; Özgüven A.A.; Gülen H.[No abstract available]Item Cross-sectional study: Long term follow-up care for pediatric cancer survivors in a developing country, turkey: Current status, challenges, and future perspectives(Turkiye Klinikleri, 2020) İncesoy Özdemir S.; Taçyildiz N.; Varan A.; Kebudi R.; Zülfikar B.; Celkan T.; Şahin G.; Çorapçioğlu F.; Keskin Yildirim Z.; Pinarli F.G.; Olgun N.; Sari N.; Dağdemir A.; Özyörük D.; Eren T.; Çakir F.B.; Adakli Aksoy B.; Bozkurt C.; Güler E.; Özgüven A.A.; Erbey F.; Berber M.; Dinçaslan H.; Ünal E.; Kantar M.Aim: The main purpose of this study is to determine the current status of long-term follow-up (LTFU) for childhood cancer survivors and the challenges of LTFU for pediatric cancer survivors at pediatric oncology institutions in Turkey. Material and methods: A questionnaire was e-mailed to the directors of 33 pediatric oncology centers (POCs) registered in the Turkish Pediatric Oncology Group (TPOG). Of these 33 active TPOG institutions, 21 participated in the study and returned their completed questionnaires. Results: Only 1 of the 21 participating centers had a separate LTFU clinic. The remaining centers provided LTFU care for childhood cancer survivors at the pediatric oncology outpatient clinic. Of these centers, 17 (80.9%) reported difficulty in transition from the pediatric clinic to the adult clinic, 14 (66.6%) reported insufficient care providers, and 12 (57.1%) reported insufficient time and transportation problems. As neglected late effects, 16 (76.1%) centers reported psychosocial and getty job problems and 11 (52.3%) reported sexual and cognitive problems. None of the centers had their own LTFU guidelines for their daily LTFU practice. Conclusion: This study was the first to gain an overview of the needs of POCs and the gaps in survivorship services in Turkey. The results from this study will help to develop a national health care system and national guidelines for pediatric cancer survivors. © TÜBİTAK.Item Common viral respiratory infections in children with cancer during the COVID-19 pandemic: a multicenter study from Türkiye(Turkish National Pediatric Society, 2024) Kaçar D.; Kebudi R.; Özyörük D.; Tuğcu D.; Bahadır A.; Özdemir Z.C.; Özgüven A.A.; Orhan M.F.; Yıldırım A.T.; Albayrak C.; Kartal İ.; Sarı N.; Tokgöz H.; Albayrak M.; Ayhan A.C.; Eroğlu N.; Aydın S.; Üzel V.H.; Zülfikar B.; Yıldırım Ü.M.; Büyükavcı M.; Gülen H.; Töret E.; Bör Ö.; Özbek N.Y.; İlhan İ.E.; Yaralı N.Background. Microbiologic confirmation of respiratory tract infections gained importance during the coronavirus disease 2019 (COVID-19) pandemic. This study retrospectively evaluated seasonal distribution, clinical presentation, and complications of respiratory viral infections (RVIs) other than COVID-19 in children with cancer during and after the pandemic lockdown. Methods. Two hundred and sixty-five inpatient and outpatient RVI episodes in 219 pediatric cancer patients confirmed by multiplex reverse transcriptase polymerase chain reaction (RT-PCR) panels from 13 centers were enrolled. Results. Eighty-six (32.5%) of the total 265 episodes occurred in 16 months corresponding to the lockdowns in Türkiye, and the remaining 67.5% in 10 months thereafter. Human rhinovirus/enterovirus (hRE) (48.3%) was the most common agent detected during and after lockdown. Parainfluenza virus (PIV) (23.0%), influenza virus (9.8%), and respiratory syncytial virus (RSV) (9.1%) were the other common agents. The 28.7% of episodes were lower respiratory tract infections (LRTIs), and complications and mortality were higher than upper respiratory tract infections (URTIs) (25.0% vs 5.3%). Bacteremia was identified in 11.5% of culture-drawn episodes. Treatment delay in one-third and death within four weeks after RVI in 4.9% of episodes were observed. Conclusion. During the pandemic, fewer episodes of RVIs occurred during the lockdown period. Respiratory viruses may cause complications, delays in treatment, and even death in children with cancer. Therefore, increased awareness of RVIs and rapid detection of respiratory viruses will benefit the prevention and, in some cases, abrupt supportive and some antiviral treatment of RVI in children with cancer. © 2024, Turkish National Pediatric Society.
