INTRODUCTION: Lymphatic malformations (LM) are rare congenital anomalies. The traditional treatment is surgical excision, but intralesional sclerosing agent injection is now preferred because of frequent recurrences after surgery, poor cosmetic results, and a high complication rate. We aimed to evaluate the efficacy of sclerosing agent injection used in the treatment of LMs in children. MATERIALS AND METHODS: We retrospectively analyzed the age, gender, admission symptoms, physical examination findings, radiological imaging results, treatment methods, complications, length of hospital stay, and outcomes of children treated for LM between January 2011 and January 2022. The lesion sizes of the patients who underwent sclerosant (Bleomycin) injection under general anesthesia were recorded before and after the treatment, and the difference between them was evaluated statistically. RESULTS: Fifteen patients were retrospectively analyzed. The mean age was 45.2+- 14.1 months (min:3- median:17- max:210). Of these, 10 (66.6%) were male and 5 (33.3%) were female (F/M=1/2). The mean age of male patients was 55 +- 20.1 months (min :3- max:210 months); The mean age of the female patients was 25.8 + - 11.2 (min 3- max: 66 months). Seven patients had a single dose, two had twice and six had three and more. Three patients had LM in different localisations simultaneously. After the sclerosant injection, surgery was performed on 2 patients, and the tissue that became a mass was removed. The average lesion size before the treatment was 55.2+-28.4 mm; after treatment: 23.8+-18.2mm. With the statistical analysis, it was seen that there was a statistically significant difference between the dimensions before and after the treatment (p<0.05) and the sclerosant injection had a great effect on the treatment (R:0.89). CONCLUSION: Intralesional injection of bleomycin is less effective for microcystic or mixed type LMs, but provides effective reduction for a safe surgical procedure. It is an effective treatment for macrocystic lesions.

Trichobezoar should be considered in the differential diagnosis in pediatric patients who present with complaints of abdominal pain, feeding problems, and vomiting as well as psychiatric problems.Rapunzel syndrome is a rare form of trichobezoar that can extend from the stomach to the small intestine and even to the colon. In this case report, a 9-year-old girl with autism accompanied by trichotillomania and trichophagia and diagnosed with Rapunzel syndrome is presented.

Paragangliomas and pheochromocytomas are rare tumors originating in chromaffin cells which are predominantly located in adrenal glands. This tumor is generally bilateral and much more rarely seen in pediatric patients. Sustained or paroxysmal hypertension is the most frequent sign of paragangliomas /pheochromocytoma. Here, we present a 15-year-old patient diagnosed with the complaint of blurred vision.

Sakrokoksigeal teratomlar yenidoğan döneminde en sık karşılaşılan teratomlardır. Sakrokoksigeal teratomlar sıklıkla doğumda tanı almakla beraber özellikle tip 1 ve 2 olanlar antenatal ultrasonografi takiplerinde fark edilebilmektedirler. Tedavi uygun cerrahi rezeksiyon ile sağlanmaktadır. Operasyon sonrası takip çocuk onkoloji birimi ile birlikte yapılmalıdır. Bu yazıda 22. Gebelik haftasında rutin ultrasonografi muayenesinde fark edilen sakrokoksigeal teratomu olan ve 34 hafta 1 günlük iken fetal distres sebebiyle acil sezaryen ile doğumu gerçekleştirilen bir yenidoğan vakası sunulmuştur.

Introduction: Urinary stone disease is an important health problem commonly seen in some regions of the world. Determining the etiology is important for effective treatment and prevention of recurrence. The aim of this study was to evaluate the demographic and clinical features, metabolic and other risk factors of children with urinary stone disease. Methods: A total of 766 patients with urinary stone disease presented to our pediatric nephrology department over 15 years. The patients’ demographic, clinical, and treatment data were retrospectively analyzed. Results: The mean age at diagnosis was 61.6±52.7 months. The male/female ratio was 1.15:1. There was no significant difference in age at diagnosis between the sexes. The most frequent presenting complaint overall was abdominal pain. Chronic renal failure was present in 1.8% and family history in 57.5% of the patients. Metabolic abnormalities were detected in 51% of the patients, urinary tract infection in 44.8%, and urinary tract anomalies in 13.2%. No cause could be identified in the other 22.7% of the patients. Urinary tract infection was the most common etiology in patients younger than 1 year old, while metabolic risk factors were more frequent in patients aged 1-10 years. Metabolic abnormalities included hypercalciuria (51.7%), hypocitraturia (47.5%), hyperoxaluria (39.9%), hyperuricosuria (23.4%), and cystinuria (9.4%). Bilateral and multiple stones were associated with metabolic abnormalities (p
