Combined Evaluation of IGF−1 and IGFBP−3 as an Index of Efficacy and Safety in Growth Hormone Treated Patients

Objective: Measurement of serum insulin−like growth factor−1 (IGF−1) and IGF binding protein−3 (IGFBP−3) levels has been recommended as a useful index for monitoring of growth hormone (GH) therapy in GH deficient children. In this study we aimed to evaluate IGF−1/IGFBP−3 molar ratio during GH treatment as an index of safety and efficacy

Evaluation of Thyroid Functions with Respect to Iodine Status and TRH Test in Chronic Autoimmune Thyroiditis

Objective: Chronic autoimmune thyroiditis (CAT) is the most common form of thyroiditis in childhood and a frequent cause of acquired hypothyroidism. The objective of this study was to evaluate the thyroid status of childrenand adolescents with CAT with respect to iodine status and diagnostic values of thyrotropin-releasing hormone (TRH) test

Permanent Central Diabetes Insipidus with Complete Regression of Pituitary Stalk Enlargement After 4 Years of Follow−up

A 14 year−old patient was admitted because of a history of polyuria and polydipsia. A diagnosis of central diabetes insipidus (CDI) accompanied by growth hormone (GH) and gonadotropin deficiency was made. Hypophyseal magnetic resonance imaging (MRI) of the patient demonstrated isolated pituitary stalk enlargement. Although GH deficiency and gonadotropin deficiency were transient, CDI was persistent despite the regression of the pituitary stalk enlargement over the 4 years of follow−up

Pulmonary Involvement of Diffuse Large B-cell Lymphoma with Cavitary Lesions

Abstract Diffuse large B-cell lymphoma (DLBCL) is the most common type of extranodal lymphoma. Typically disease occurs fastly growing nodal or extranodal masses with systemic symptoms. Pulmonary involvement may also occur in DLBCL. Here we present a DLBCL with cavitary lesions in the lung. A 59-year-old male was diagnosed with DLBCL through an endoscopic gastric biopsy that was performed 1.5 years ago. After six course of R-CHOP chemotherapy, the relaps of disease was confirmed with mediastinoscopy. Despite two courses of RICE chemotherapy and one course of R-BAB therapies, the patient was admitted to the intensive care unit with shortness of breath and tachypnea. Thorax computed tomography showed a mass lesion that enclosed and narrowed the right major bronchus and multiple lesions with cavitation. The infections were excluded with bronchoscopy. The patient received pulse steroid therapy, radiotherapy and three courses of Hyper-CVAD chemotherapy. In the control thorax CT, cavitary lesions got smaller, respiratory insufficiency of patient improved. When pulmonary cavitary lesions are observed in patients under follow-up with the diagnosis of lymphoma, the pulmonary involvement of lymphoma should also be considered in addition to the infectious agents

Evaluation of Permanent Growth Hormone Deficiency (GHD) in Young Adults with Childhood Onset GHD: A multicenter study

Background: Reconfirming the diagnosis of childhood onset growth hormone deficiency (GHD) in young adults is necessary to demonstrate the need for continuation of GH therapy

The comparison of systemic inflammatory response markers and Doppler ultrasound parameters between pregnancies with intrahepatic cholestasis and control cases

Objective: This study aims to detect a relationship between inflammatory markers, ductus venosus (DV) pulsatility index (PI), middle cerebral artery (MCA) PI, and umbilical artery (UA) systole to diastole ratio (S/D) and PI between pregnancies with intrahepatic cholestasis and control cases. Methods: This prospective study included 82 cases having intrahepatic cholestasis of pregnancy (ICP) and 80 gestational age-matched healthy control cases. The Doppler measurements (DV PI, MCA PI, and UA S/D and PI), inflammatory markers (neutrophil to lymphocyte ratio [NLR], platelet to lymphocyte ratio [PLR], mean platelet volume [MPV], and red blood cell distribution width [RDW]), and fetal and maternal outcomes were compared. Results: Patients with ICP had increased PLR value (p=0.019) and decreased lymphocyte count (p=0.004) compared to control cases. Also, there was a positive correlation between PLR value and the presence of ICP (χ2=5.774, p=0.016). There were no significant differences between ICP and control groups concerning NLR, RDW, MPV, and UA PI values. We found higher UA S/D, and DV PI values and lower MCA PI values in pregnancies with ICP compared to controls (p<0.001, p=0.026, and p=0.003, respectively). Conclusion: In ICP cases, the PLR value was significantly increased than the controls, but the NLR, RDW, MPV, and UA PI values were found to be similar to control cases. The UA S/D, and DV PI values were increased, and MCA PI was significantly decreased in the ICP group compared to healthy pregnancies. However, we could not demonstrate the benefit of Doppler measurements in predicting neonatal outcomes in ICP cases

Comparison of the Reliability of the “GÖK Atlas” and the “Gilsanz-Ratib Atlas” in the Determination of Bone Age in Turkish Children

Aim: In this study we aimed to evaluate which of the GÖK and GR atlases is more compatible with chronological age in Turkish children aged 5-10 years. Material and Method: In this study, the wrist radiographs of patients aged 5-10 years who applied to İzmir Bakırçay University Çiğli Training and Research Hospital due to trauma were retrospectively analyzed. A total of 360 wrist radiographs were evaluated. Bone age estimates in both groups were compared with chronological ages. Results: In the correlation analysis, the prediction rate with 1-difference tolerance is 88.9% in the GR atlas and 76.7% in the GÖK atlas, while both atlases predict 99% correctly with two-difference tolerance. GR Atlas 168 (46.2%) and GÖK Atlas 147 (40.8%) predicted correctly regardless of gender and age. Of the correct estimations, 53.5% in the GR atlas and 57.8% in the GÖK atlas were male cases. İn male age group at the age of 6 and 10, the GR atlas is more successful, at the age of 7, the GÖK Atlas is more successful, and at the age of 5, 8, and 9 the success of both atlases is the same. İn female age group at the age of 5,7, 8, and 10 the GR atlas is more successful, at the age of 6 and 9 the GÖK Atlas is more successful Conclusion: The GR Atlas was more accurate than the GÖK Atlas. Both the GR Atlas and the GÖK Atlas predicted more accurately in males. Since reference values for bone age can change with environmental and genetic factors all over the world, it is beneficial for all races to create atlas models with multicenter studies in order to establish their own standards

Do Fetal Isolated Mild Venticulomegaly Make Any Difference in Regional ADC Values at Magnetic Resonans Imaging?

Objective: Ventriculomegaly may not only develop secondary to a process,but it may also be in the form of isolated ventriculomegaly with no specific reason. MRI is performed to show the presence of accompanying pathologies.In this study, we measured ADC values in mild ventriculomegaly cases and aimed to investigate the role of ADC value measurements in predicting neurological prognosis in isolated mild ventriculomegaly during MRI. Methods: In our study, ADC values were measured of 37 patients detected to be present with mild ventriculomegaly and 17 fetuses in the control group who had no additional central nervous system patology. For the measurement, ROI was placed in differtent brain regions (frontal lobe white matter,occipital lobe white matter, basal ganglia, thalamus, cerebellum and pons). The analysis of the data obtained was performed using the SPSS (20th version) program. MannWhitney U test was applied. Statistical significance level was set as p<0.05. Results: There was no statistically significant difference between the isolated mild ventriculomegaly and the control group in terms of the mean maternal age (p=0.160). Also, no statistically significant difference was observed between the mean gestational age in the ventriculomegaly group and the control group (p=0.890). There was also no statistically significant difference between ADC measurements in different brain regions in the isolated mild ventriculomegaly and the control group (p=0.807). Conclusion: In order to determine the prognosis in isolated mild ventriculomegaly, other quantitative parameters such as ADC measurement, beyond morphological evaluation and diameter measurement should be determined, and also we need more studies comprising more cases in this field
