Introduction: The purpose of this study was to establish the reference value of normal thickness of thyroid isthmus among clinically euthyroid Nepalese individuals using Ultrasonography and correlate this with thyroid volume, sex, individual’s built and geographic location.Methods: This was a prospective cross sectional study involving 485 clinically euthyroid individuals. B -mode Ultrasonography was used to measure the thickness of thyroid isthmus in transverse plane. Mean thickness of isthmus for male and female was obtained and Pearson correlation test was used to see the relationship with various factors.Results: Among 485 individuals between 1 to 83 years of age, 221 were males and 264 were females. Maximum individuals (72.99%) were from hilly region and minimum (3.30%) were from Himalayan region. Mean thickness of isthmus was 3.097 ± 1.009 mm (range 1.0 to 6.8 mm). It was 3.114 ± 0.9513 mm for male and 3.083 ± 1.056 mm for female. Isthmus thickness best correlated with total thyroid volume (r=0.373, p=0.0001). Isthmus thickness also positively correlated with body mass index (r=0.355, p =0.0001), body surface area (r= 0.296, p=0.0001), weight (r =0.334, p=0.0001) and height (r =0.130, p =0.004) of the individuals.Conclusion: This study estimated the normal reference value of thyroid isthmus thickness. As isthmus thickness correlated well with total thyroid volume, it can roughly guide the thyroid volume and help assessment of thyroid size in diffuse thyroid disease.

“…The length of the isthmus of thyroid gland in the present study was lower than Maharashtrian population reported by Joshi et al, 15 and the length was lower than Bangladeshi people reported by Begum M 13 and more than Bangladeshi people reported by Sultana et al, 16 in Group A, B and C. The height of the isthmus of thyroid gland in the present study was similar to that of Maharashtrian population reported by Joshi et al, 15 and the height was lower than Bangladeshi population reported by Begum M 13 and Sultana et al, 16 in Group A, B and C.…”

“…Many authors have studied PLLA degradation, in relation to such aspects as pH, crystallinity, and the % of absorbed water, among others . However, there are relatively few results on the effects of nanoparticles such as nanohydroxyapatite (nHA) on PLLA aging and degradation behavior . The fabrication technique used in this investigation was thermally induced phase separation (TIPS) (lyophilization), as well as the incorporation of nHA before the fabrication of the scaffold, a technique that permitted homogeneous dispersion of the nHA particles.…”

In vitro degradation of PLLA/nHA composite scaffolds

Porous Poly‐l‐lactide (PLLA) scaffolds and PLLA/nanohydroxyapatite (nHA) composite scaffolds with interconnected pore networks and a porosity of over 90% were fabricated with lyophilization techniques. In this study, the degradation behavior of PLLA and PLLA/nHA composite scaffolds is investigated over 8 weeks in phosphate buffer solution at 37°C. Thermal analysis using differential scanning calorimetry (DSC) showed that the percent crystallinity of all the samples increased by approximately 10%, which represents a considerable increase in the glass transition temperature. The melting range enthalpy of the scaffolds did not change to lower temperatures as would be expected. The spectroscopic analysis performed by Fourier transform infrared spectroscopy suggested that nHA particles should not appreciably affect the absorbance pattern when evenly mixed with the PLLA. This is consistent with the analysis of the scaffold microstructure and morphology with scanning electron microscopy, which drew a low content of nHA with no significant effect on solvent crystallization or pore structure. The compressive modulus and the yield strength of the scaffolds were investigated in conjunction with the study of their degradation rates. In comparison with the mechanical properties of the PLLA scaffolds, which remained largely unchanged, those of the PLLA/nHA composite scaffolds decreased as the degradation progressed. POLYM. ENG.
