    Calcinosis cutis in a pediatric patient with Burkitt's lymphoma
    (2005) Gülen H.; Kazanci E.; Özek D.G.; Erbay A.; Yamaci S.; Aktaş S.; Vergin C.
    Calcinosis cutis, an uncommon disorder characterized by hydroxyapatite crystals of calcium phosphate deposited in the skin, has been described infrequently in childhood. Cutaneous calcification may be divided into four major categories: dystrophic, metastatic, idiopathic, and iatrogenic. Here, we report an example of iatrogenic type with a 4-year-old boy who diagnosed with Burkitt's lymphoma, and developed calcinosis cutis secondary to a tumour lysis syndrome with induction chemotherapy.

    A rare familial thrombocytopenia: May-Hegglin anomaly report of two cases and review of the literature
    (2006) Gülen H.; Erbay A.; Kazanci E.; Vergin C.
    May-Hegglin anomaly is a hereditary thrombocytopenia associated with giant platelets and large basophilic, cytoplasmic inclusion bodies (resembling Döhle bodies) in the granulocytes. Patients may experience easy bruising, recurrent epistaxis, gingival bleeding, menorrhagia and sometimes excessive bleeding associated with surgical procedures. Failure to appropriately diagnose May-Hegglin anomaly could result in inappropriate treatment. In states of chronic thrombocytopenia associated with large platelets, including chronic idiopathic thrombocytopenic purpura, May-Hegglin anomaly should be considered in the differential diagnosis. In this case report, we present a five-year-old girl previously followed as idiopathic thrombocytopenic purpura without bleeding symptoms and a 14-year-old boy who were diagnosed with May-Hegglin anomaly. © Turkish Society of Hematology.

    Sinopulmonary aspergillosis in children with hematological malignancy
    (2006) Gulen H.; Erbay A.; Gulen F.; Kazanci E.; Vergin C.; Demir E.; Tanac R.
    Invasive pulmonary aspergillosis is a serious infectious complication in immunocompromised especially neutropenic patients. Despite improvements in early diagnosis and effective treatment, invasive pulmonary aspergillosis is still a devastating opportunistic infection. These infections also interfere with the anticancer treatment. We report our experience in the diagnosis and therapeutic management of sinopulmonary aspergillosis in 4 children with hematologic malignancy. All patients except the first were neutropenic when sinopulmonary aspergillosis was diagnosed. Clinical signs included fever, cough, respiratory distress, swallowing difficulty, headache, facial pain-edema and hard palate necrosis. Radiodiagnostic methods showed bilateral multiple nodular infiltrations, soft tissue densities filling all the paranasal sinuses, and bronchiectasis. Diagnosis of aspergillosis was established by bronchoalveolar lavage in one case, tissue biopsy, positive sputum and positive cytology, respectively, in the other 3 cases. One patient was treated with liposomal amphotericin B and other 3 cases were treated with liposomal amphotericin B + itraconozole. Outcome was favorable in all cases except the one who died due to respiratory failure. Early diagnosis, appropriate treatment and primary disease status are important factors on prognosis of Aspergillus infections in children with hematological malignancy.

    Treatment of intrathecal methotrexate overdose with folinic acid rescue and lumbar cerebrospinal fluid exchange: A report of two cases; [Yüksek doz intratekal metotreksat'ın folinik asit ve beyin omurilik sıvısı deg̈işimi ile tedavisi: Ïki olgu sunumu]
    (Turkish Society of Hematology, 2011) Kazanci E.; Gülen H.; Erbay A.; Vergin C.
    We report two male cases (4- and 5-years-old) of intrathecal methotrexate overdose. The two boys with acute lymphoblastic leukemia were to receive intrathecal injection of methotrexate. Instead of the prescribed 12 mg, they both received a dose of 120 mg. The initial cerebrospinal fluid samples showed methotrexate concentration of 2.24×10-2M in case 1 and 1.32×10-2M in case 2. The cases were successfully treated with cerebrospinal fluid (CSF) exchange and intravenous folinic acid rescue. The favorable outcome in our cases suggests that CSF exchange is safe and that folinic acid rescue may be adequate to prevent sequelae in patients subjected to intrathecal MTX overdoses up to 120 mg. We propose CSF exchange and intravenous folinic acid as the mainstay of treatment. In addition to the staff 's failure to check the drug label carefully, the marked resemblance of the two dose preparations of MTX may have been contributory.
