    A Case with Mega Cisterna Magna Renal and Ear Anomalies: Is This a New Syndrome?
    (Hindawi Ltd, 2013) Konca, Capan; Caliskan, Bahar; Tas, Mehmet Ali
    Background. Extrarenal pathologies may be associated with renal position and fusion anomalies. According to the literature, our patient is the first horseshoe kidney case that had mega cisterna magna, arachnodactyly, and mild mental retardation. Case Report. A 9-year-old boy admitted because of the myoclonic jerks. He had a dysmorphic face, low-set and cup-shaped ears, arachnodactyly, and mild mental retardation. The patient's laboratory findings were normal except for a mild leucocytosis and hypochromic microcytic anemia. His cerebrospinal fluid was cytologically and biochemically normal. Cranial MRI revealed 1.5 cm diametered mega cisterna magna in the retrocerebellar region. Although there were no significant epileptical discharges in the electroencephalography, there were slow wave discharges arising from the anterior regions of both hemispheres. Because he had stomachache, abdominal ultrasonography was performed, and horseshoe kidney was determined. Abdominal CT did not reveal any abnormalities except the horseshoe kidney. There were not any cardiac pathologies in echocardiography. He had normal 46XY karyotype and there were no repeated chromosomal derangements, but we could not evaluate for molecular and submicroscopic somatic changes. He was treated with valproic acid and myoclonic jerks did not repeat. Conclusion. We suggest that the presence of these novel findings may represent a newly recognized, separate syndrome.

    Childhood Brucellosis in Southeastern Region of Turkey: A retrospective analysis
    (Dr Behcet Uz Cocuk Hastaliklari Ve Cerrahisi, 2013) Konca, Capan; Tutanc, Murat; Gunes, Ali; Tas, Mehmet Ali
    Objective: To evaluate the clinical and laboratory findings, treatment modalities and outcomes of children with brucellosis in a four-year period Methods: This retrospective study included 34 children who were admitted to Dicle University Pediatric Infectious Diseases Service with brucellosis between 2003-2007. Demographic features, clinical symptoms, physical examination and laboratory findings of patients were evaluated. The standard tube agglutination test, Rose Bengal test and clinical findings were used as diagnostic criteria for brucellosis. Results: In the study, twelve patients (35%) were female and 22 (65%) were male. The mean age was 9.2+/-3.4 years. Twenty-one patients (61.7%) were from rural areas of Turkey. All of the children except two patients have reported to consume unprocessed milk and dairy products. The most frequent complaints and clinical findings were fever (88.2%) and musculo-skeletal system symptoms (76.4%). Hematological involvement was significantly apparent in laboratory results. Trimethoprimsulfamethoxazole+ rifampicin were administered to children smaller than 8 years and doxycycline+ rifampicin to children older than 8 years during 6 weeks for treatment. Four patients were relapsed. Conclusion: Musculoskeletal system complaints and fever are the most common symptoms in brucellosis. Brucellosis should be considered in the differential diagnosis of patients with hematological signs. Combined treatments should be administered within a sufficient period to provide successful treatment and prevent relapse.

    Children with breakthrough varicella infection requiring hospitalization in Turkey (VARICOMP Study 2008-2013)
    (Elsevier Sci Ltd, 2015) Dinleyici, Ener Cagri; Kurugol, Zafer; Kara, Ates; Tezer, Hasan; Tas, Mehmet Ali; Guler, Ekrem; Yasa, Olcay
    Introduction: Varicella in previously immunized individuals, known as breakthrough varicella. While the majority of breakthrough cases are mild, some may be severe, requiring hospitalization in previously healthy children or children with an underlying condition. Methods: This report, as a part of the prospective national pediatric varicella hospitalizations study (including 29 centers, represent 50% of pediatric population) in Turkey, is aimed to evaluate breakthrough varicella infection requiring hospitalization before the routine use of single-dose live varicella vaccine in national program from 2008 to 2013 (<10% of the pediatric age group received a single-dose vaccine). Results: In the time period, 1939 children were hospitalized due to varicella infection in Turkey; 36 children (20 boys, 16 girls, mean age 68.0+37.6 months, all received single dose live varicella vaccine) with breakthrough varicella infection. Breakthrough varicella infection might be severe in previously healthy children (61.1%) and children with immune-compromising conditions (38.9%). The time elapsed between vaccination and hospitalization was approximately 5 years, and neurological complications, mainly encephalitis and meningitis, were the most common reason for hospitalization in previously healthy children. Conclusion: Pediatric breakthrough varicella requiring hospitalization have been seen in Turkey, is mainly observed in previously healthy children at 5 years after a single-dose varicella vaccine. The varicella vaccine has been implemented as part of the National Immunization Program in Turkey in 2013 (a single dose at age 12 months). Further surveillance in the same settings could evaluate the effectiveness of national immunization with single-dose varicella vaccine at 12 months of age and potential need for second dose of vaccine.

    Elevated Plasma Levels of N-terminal pro-Brain Natriuretic Peptide in Children with Acute Poststreptococcal Glomerulonephritis
    (Tohoku Univ Medical Press, 2009) Taskesen, Mustafa; Taskesen, Tuncay; Katar, Selahattin; Karadede, Abduelaziz; Tas, Mehmet Ali
    Acute poststreptococcal glomerulonephritis (APSGN) is the most common prototype of acute glomerulonephritis in children, and is characterized by the sudden onset of gross hematuria, edema, hypertension and volume overload. Brain natriuretic peptide (BNP) is produced in both the brain and the heart. Its prohormone, proBNP, is cleaved to biologically active BNP and an inactive N-terminal peptide of proBNP (NT-proBNP). NT-proBNP is released predominantly from the ventricles in response to hypervolemia and pressure overload. We therefore investigated the relationship between NT-proBNP levels and cardiac functions of patients with APSGN. NT-proBNP levels were measured in 28 patients with APSGN (17 boys and 11 girls of 8.2 +/- 2.9 years old) and in 26 healthy children (control group). Echocardiograms were performed in both patient and control groups on admission, and only in the patient group two weeks later. Upon admission, the plasma NT-proBNP levels were higher in the patients than in the control group (8876.2 +/- 9650.8 vs 69.5 +/- 22.2 pg/mL, p < 0.001), and left ventricular dysfunction was detected in six patients. Moreover, NT-proBNP levels were significantly higher in the patients with left ventricular dysfunction than other patients (n = 22). There was no significant difference in the levels of NT-proBNP between the patient and control groups, after diuretic treatment of the patients. Plasma NT-proBNP levels were positively correlated with the severity of APSGN. Thus, NT-proBNP level may be a useful marker to assess the volume overload and cardiac function in the follow up of selected APSGN patients.

    Hereditary Spherocytosis: Evaluation of 68 Children
    (Springer India, 2015) Konca, Capan; Soker, Murat; Tas, Mehmet Ali; Yildirim, Ruken
    To determine the clinical and hematologic features of 68 children with hereditary spherocytosis (HS). In this retrospective study, we analyzed recorded information of 68 HS patients diagnosed between March 1997 and March 2007, including clinical manifestations at admission, gender, median age at diagnosis, family history, hematologic and biochemical data, patient management, complications, median age of splenectomy, and median follow-up time. Sixty-eight patients with HS (36 male and female) were investigated. The median age at diagnosis was 5.6 years (range 3 months to 18 years). Twenty-seven (39.7 %) had parents with consanguineous marriages, and 20 (29.4 %) had parents with first-degree consanguinity. Predominant clinical manifestations at admission were anemia in 59 patients (86.76 %), splenomegaly in 49 (72.05 %), and jaundice in 33 (48.52 %). Patients were classified as mild, moderate, or severe in 29.4, 61.7, and 8.8 % of patients, respectively. Five patients (7.3 %) underwent splenectomy. Major complications of HS were hemolytic, aplastic, and megaloblastic crises and cholelithiasis in 7 (10.2 %), 1 (1.4 %), 7 (10.2 %), and 6 (8.8 %) of patients, respectively. There were no deaths during follow-up. HS should be considered in evaluating possible diagnoses in patients with hemolytic anemia. In this study, the clinical course of patients with HS was relatively benign, with low proportions of patients having splenectomized and aplastic crises.

    A rare cause of severe periorbital edema and dermonecrotic ulcer of the eyelid in a child: Brown recluse spider bite
    (Turkish J Pediatrics, 2011) Taskesen, Mustafa; Akdeniz, Sedat; Tas, Taskin; Keklikci, Ugur; Tas, Mehmet Ali
    Spider bites are a worldwide problem. Brown recluse spider bites can lead to severe local or systemic clinical effects, such as edema, necrotic ulcer, rashes, fever, chills, nausea, vomiting, malaise, arthralgia, myalgia, hemolysis, leukocytosis, disseminated intravascular coagulation, renal failure, and death. Eyelid bites from brown recluse spiders are rare. We report a child with severe facial edema and a dermonecrotic ulcer on the eyelid. Upon laboratory examination, leukocytosis with a significant left shift was detected. The patient was treated with antibiotics, systemic corticosteroid and conservative therapy that included saline compresses and ocular lubrication. No surgical excision was required. Vision was not impaired. A dermonecrotic ulcer is a severe complication of brown recluse spider bites. Since the diagnosis is difficult, clinical and epidemiological findings and a detailed history are important for an accurate diagnosis.

    Splenectomy in patients with thalassemia major: Evaluation of 35 cases
    (Dr Behcet Uz Cocuk Hastaliklari Ve Cerrahisi, 2013) Konca, Capan; Yildirim, Ruken; Dikici, Bünyamin; Tas, Mehmet Ali
    Objective: Beta-thalassemia is common, worldwide, autosomal recessive and inherited type of anemia which results from absent or reduced synthesis of beta globin. Splenectomy may be performed for the treatment of many hematologic diseases. The aim of this study is to discuss recorded data of thalassemia major patients who underwent splenectomy. Methods: The records of 782 patients with thalassemia major were reviewed retrospectively. Of these patients, 35 splenectomized patients with available data were included in the study. Recorded data of patients were evaluated as for age at diagnosis, gender, age at splenectomy, surgical indications, chelation therapy, annual transfusion requirements, and postoperative clinical response. Statistical analyses were performed with statistical package of SPSS version 13.0. Results: Twenty-two (63%) male and 13 (37%) female patients were included in the study. Mean age at diagnosis was 8 +/- 2 months and splenectomy was 8.5 years. The main indication for splenectomy was increased transfusion requirement (57.14%). The annual transfusion requirement reduced from preoperative 235 +/- 30 mL/kg to 115 +/- 15 mL/kg postoperatively. Mean serum ferritin levels were 1745 +/- 761 ng/mL, and 1985 +/- 570 ng/mL before, and after splenectomy. None of the patients developed any complications such as sepsis or coagulation disorder. Conclusion: These results suggest that splenectomy is beneficial to improve the quality of the lives of patients and significantly reducing blood consumption. Inadequate iron chelation therapy may be associated with progression to splenectomy.
