SummaryGlycated hemoglobin (HbA1c) is used for the assessment of glycemic control in patients with diabetes. The presence of genetic variants of hemoglobin can profoundly affect the accuracy of HbA1c measurement. Here, we report two cases of Hemoglobin G-Coushatta (HBB:c.68A>C) variant that interferes in the measurement of HbA1c by a cationexchange HPLC (CE-HPLC) method. HbA1c was measured by a CE-HPLC method in a Tosoh HLC-723 G7 instrument. The HbA1c levels were 2.9% and 4%. These results alerted us to a possible presence of hemoglobinopathy. In the hemoglobin variant analysis, HbA2 levels were detected as 78.3% and 40.7% by HPLC using the short program for the Biorad Variant II. HbA1c levels were measured by an immunoturbidimetric assay in a Siemens Dimen sion instrument. HbA1c levels were reported as 5.5% and 5.3%. DNA mutation analysis was performed to detect the abnormal hemoglobin variant. Presence of Hemoglobin G-Coushatta variant was detected in the patients. The Hb G-Coushatta variants have an impact on the determination of glycated hemoglobin levels using CE-HPLC resulting in a false low value. Therefore, it is necessary to use another measurement method.Keywords: Hb G-Coushatta (HBB:c.68A>C), HbA1c, cation-exchange HPLC Kratak sadr`ajGlikolizirani hemoglobin (HbA1c) koristi se za procenu glikemijske kontrole kod obolelih od dijabetesa. Prisustvo genetskih varijanti hemoglobina mo`e sna`no uticati na ta~nost merenja HbA1c. Ovde je prikazan izve{taj o dva slu ~aja gde je varijanta hemoglobina G-Coushatta (HBB:c.68A>C) uticala na merenje HbA1c metodom HPLC sa katjonskom izmenom (CE-HPLC). HbA1c meren je metodom CE-HPLC na instrumentu Tosoh HLC-723 G7. Nivoi HbA1c bili su 2,9% i 4%. Ovi rezultati ukazali su nam na potencijalno prisustvo hemoglobinopatije. Prilikom analiziranja varijante hemoglobina, otkriveni su nivoi HbA2 od 78,3% i 40,7% metodom HPLC uz kori{}enje kratkog programa za Biorad Variant II. Nivoi HbA1c mereni su pomo}u imunoturbidimetrijskog eseja na instrumentu Siemens Dimension. Dobijeni su nivoi HbA1c od 5,5% i 5,3%. Analiza mutacije DNK izvedena je kako bi se otkrile abnormalne varijante hemoglobina. Kod pacijenata je otkriveno prisustvo varijante hemoglobina G-Coushatta. Va rijante Hb G-Coushatta uti~u na odre|ivanje nivoa glikoliziranog hemoglobina pomo}u metode CE-HPLC, {to ima za posledicu la`no niske vrednosti. Dakle, neophodno je primeniti druge metode merenja.

Purpose: The reason behind the balance control disorder seen in adolescent idiopathic scoliosis (AIS) has been suggested as a central nervous system dysfunction, yet it has not been investigated in detail whether this problem originates from sensory, motor, or from both systems. This study aimed to reveal the differences in the pathways that provide proprioceptive sense, motor control, and coordination between these 2 systems in female individuals with AIS. Methods: Brain Diffusion Tensor Imaging was applied to 30 healthy individuals and 30 Lenke type 1 AIS patients. All of the individuals included in the study were predominantly righthanded and aged between 10 and 18. Diffusion tensor imaging of both groups were performed bilateral tractography on the corticospinal tract (CS tr), medial lemniscus (ML), superior longitudinal fasciculus (SLF), and inferior longitudinal fasciculus (ILF) tracts using DSI Studio software. Results: Significant differences in the parameters of CS tr, ML, SLF, ILF pathways were found between the AIS and the control groups. In the AIS group, significant differences were found in the fiber count and fiber ratio of the ML that carries the proprioceptive sense and CS tr, which is responsible for the somatomotor system. There were also significant differences between the left and right CS tr, ML, SLF, and ILF pathways of the AIS group (P < 0.05). Conclusions: Differences in the CS tr, ML, SLF, and ILF pathways may trigger muscular asymmetry and cause postural instability and thus spinal deformity in AIS.
