Öğe A COMPARATIVE REVIEW OF PEDIATRIC AND ADULT PATIENTS WITH MILIARY TUBERCULOSIS(Modestum Ltd, 2007) Tanrikulu, Cetin; Gurkan, Fuat; Dagli, Canan Eren; Gozu, Ayfer; Suner, AliAim: Miliary tuberculosis (MTB) is a serious and rare form of tuberculosis. Studies comparatively reviewed children and adults with MTB are lacking. Methods: We retrospectively evaluated 56 pediatric and 26 adult MTB patients at a university hospital, between 1990 and 2003 Results: The median age at presentation was 3.5 years for children and 38 years for adults. Thirtyeight of all patients of whom 86.8% were children had family history of tuberculosis Presenting symptoms and signs of adult and pediatric patients were loss of weight (51.8% vs. 61.5%), anorexia (76.9% vs. 57.8%), dyspnea (12.5% vs. 57.8%), diarrhea/ vomiting (35.0% vs. 27.0%), fever (53.8% vs. 17.9%), hepatomegaly (30.8% vs. 51.8%), pulmonary crepitations (42.3% vs. 42.9) and cough (46.2% vs. 35.7%), respectively. The presenting symptoms/signs and laboratory abnormalities were generally more frequent in adults. Detected laboratory abnormalities were leukocytosis (73.2%), increased sedimentation rate ( 73.2%), anemia (52.4%), hypoalbuminemia (47.6%), elevated liver transaminases (36.6%), elevated lactate dehydrogenase (50.0%) and hyponatremia (25.6%) in whole study group. The diagnosis was proven microbiologically in 15 (18.3%) patients. Among 56 pediatric cases, there were 8 (14.3%) children with positive BCG scar and only 16 (28.6%) children with positive reaction to 5TU tuberculin test. Radiological findings of all patients, either on chest X-ray or high resolution computerized tomography, were characteristic for MTB. One fourth of patients had accompanying tuberculous meningitis. Predisposing factors for TB were found in 13 patients (15.9%). No patients had HIV infection. Overall 6 (7.3%) patients had died. Conclusion: High rate of history of family contact and low rate of BCG vaccination in our patients with MTB were significant public health problems. Identifying different features in children and adults may contribute to early diagnosis of MTB, which is highly relevant to its outcome.Öğe The effect of malnutrition on kidney size in children(Springer, 2007) Ece, Aydin; Gozu, Ayfer; Bukte, Yasar; Tutanc, Murat; Kocamaz, HalilMalnutrition is a widespread disorder in children, and ultrasonography is the method of choice to estimate kidney dimensions. Previously, kidney sizes had been studied in healthy newborns and in pediatric patients; however, kidney sizes were not investigated sufficiently in malnourished children. The study group consisted of 74 children with energy malnutrition (marasmus), and the control group consisted of 47 healthy children. Kidney sizes were mesaured by the same radiologist using ultrasonography. The mean age of the marasmic group was 29.6 +/- 14.0 months. Malnourished children had significantly lower kidney length and renal volume but higher relative kidney volume (cm(3)/body weight) compared with controls (P < 0.05). The mean length and volume of left kidney were higher than those of right kidney in both marasmic and control groups (P < 0.05). The strongest positive correlations were found between body height and kidney length, depth and volume in marasmic group. Regression analysis revealed that height and age of marasmic children had a significant effect on kidney volume; however, only body height had an effect on kidney length. In conclusion, malnourished children had smaller kidney sizes, and body height was the main determinant of their kidney length and volume. The potential long-term detrimental consequences of poor renal growth in malnutrition need to be investigated.Öğe Neurological presentations of nutritional vitamin B12 deficiency in 42 breastfed infants in Southeast Turkey(Tubitak Scientific & Technological Research Council Turkey, 2011) Taskesen, Mustafa; Yaramis, Ahmet; Katar, Selahattin; Gozu, Ayfer; Pirinccioglu, Ayfer Gozu; Soker, MuratAim: Nutritional vitamin B12 deficiency is common in developing and underdeveloped countries and has a wide variety of neurological presentations. The aim of this study was to evaluate the neurological characteristics and laboratory results of infants with vitamin B12 deficiency. Materials and methods: A total of 42 infants were included in this study. All patients were evaluated for clinical, physical, and neurological abnormalities, and an attempt was made to obtain short-term neurologic follow-up. Results: Of 42 patients, 24 (57%) were boys and 18 (43%) were girls. The average age at diagnosis was 13.04 +/- 5.68 months. Most of these infants were breastfed only and born from mothers with inadequate animal-derived protein consumption. Hypotonia (100%), anorexia (92.8%), neurodevelopmental (85.7%), and social (80.9%) retardation were the most present symptoms in all infants. Conclusion: Severe neurological and hematological findings may be found in children with vitamin B12 deficiency. Early diagnosis and treatment is crucial in cases of hematological complications and neurologic impairment. Neurologic impairment may be irreversible if the diagnosis is delayed beyond 12 months. We think that dietary management, such as nutritional support with vitamin B12 for the mothers during pregnancy and complementary food for infants, may prevent the neurological deficits and neurodevelopmental retardation.Öğe Prevalence of Hepatitis B Infection among Schoolchildren in Southeast Turkey(Tubitak Scientific & Technological Research Council Turkey, 2009) Dikici, Bünyamin; Uzun, Hakan; Gozu, Ayfer; Fidan, MuecahitAim: Hepatitis B virus (HBV) infection is a worldwide health problem. The objectives of this study were to determine the impact of the Expanded Programme on Immunization (EPI) on the prevalence of HBsAg carrier rate and immunity developed against HBV infection among schoolchildren in southeast Turkey. Materials and Methods: The study population consisted of 147,200 healthy schoolchildren between 6 to 17 years of age living in the Mardin area. A total of 802 children were randomly selected by systematic sampling method. Hepatitis B surface antigen (HBsAg), antibody to HBsAg (anti-HBs), and antibody to hepatitis B core antigen (anti-HBc) were analyzed in blood samples by enzyme-linked immunosorbent assay (ELISA General Biological Corp., Taiwan). Results: This study involved 420 (52.4%) male and 382 female (47.6%) schoolchildren with a mean age of 10.4 +/- 2.3 years. The overall anti-HBs. anti-HBc, and HBsAg were positive in 724 (90.2%), 56 (7%), and 22 (2.7%) children. respectively. The overall HBV seroprevalence rate was 2.7%. Conclusions: The introduction of the national EPI has successfully decreased the HBV seropositivity possibly by preventing perinatal and horizontal HBV transmission among schoolchildren in southeast Turkey.Öğe Sympathetic overactivity in patients with pulmonary stenosis and improvement after percutaneous balloon valvuloplasty(Wiley, 2008) Alyan, Omer; Ozdemir, Ozcan; Kacmaz, Fehmi; Topaloglu, Serkan; Ozbakir, Cemal; Gozu, Ayfer; Korkmaz, SuleObjective: Percutaneous balloon valvulotomy (PBV) is the procedure of choice for the treatment of valvular pulmonary stenosis (PS) with similar results comparable to surgical valvotomy but less invasive. . Methods and Results: Twenty-seven consecutive patients with PS being evaluated for PBV were enrolled in the study. Peak instantaneous transvalvular gradient, right ventricle (RV) diameter, mean atrial pressures, RV systolic pressure (RVSP), pro-brain natriuretic peptide (proBNP) levels significantly decreased immediately after PBV. Regarding heart rate variability (HRV) parameters, mean HR (heart rate), LF (low frequency) day and night, LF/HF day and night significantly decreased and standard deviation of all NN intervals (SDNN), root mean square of successive differences (RMSSD), P number of NN intervals that differed by more than 50 ms from adjacent interval divided by the total number of all NN intervals (PNN50), HF (High frequency) day and night significantly increased 1 day after PBV and these changes were shown to be preserved at the first month. The increase in SDNN was correlated with the decrease in right atrial pressure (RAP) (r = -0.5, P = 0.04); the increase in standard deviation of the 5-minute mean RR intervals (SDANN) was correlated with the decrease in proBNP (r = -0.4, P = 0.03). Conclusions: Sympathetic overactivity and increased proBNP levels were associated with the symptomatic status of patients with PS. Associated with a decrease in atrial pressures and proBNP levels, PBV yielded a decrease in adrenergic overactivity in the patients with PS.
