Penanda kadar pusing ganti tulang (PPT) adalah berguna dalam penilaian status kesihatan tulang. Namun, pengaruh umur, kumpulan etnik dan antropometri badan terhadap aras PPT dalam kalangan lelaki masih belum jelas. Kajian ini bertujuan untuk menentukan pengaruh faktor-faktor tersebut terhadap aras PPT, iaitu aras osteokalsin (OC) dan telopeptida terminal-C kolagen jenis 1 (CTX-1) dalam kalangan lelaki Cina dan Melayu berumur 20 tahun dan ke atas (N = 407) di Lembah Klang. Subjek dikumpulkan melalui kaedah persampelan bertujuan. Ketinggian, berat badan dan indeks jisim badan subjek telah diukur. Darah mereka diambil pada waktu pagi untuk analisis aras OC dan CTX-1 serum dengan asai imunoserap terangkai enzim. Hasil kajian menunjukkan aras OC dan CTX-1 adalah lebih tinggi secara signifi kan dalam kalangan lelaki Melayu berbanding dengan lelaki Cina (p < 0.05). Aras OC dan CTX-1 adalah paling tinggi dalam kalangan lelaki berumur 20-29 tahun, dan kemudiannya menurun secara signifi kan berbanding dengan dekad sebelumnya dalam kalangan lelaki berumur 30-39 tahun (p < 0.005). Perbezaan aras kedua-dua PPT ini adalah tidak signifi kan di antara lelaki berusia 30-39 tahun dengan lelaki yang lebih tua (> 40 tahun dan ke atas) (p > 0.005). Aras OC berkorelasi secara signifi kan dan negatif dengan berat dan indeks jisim tubuh subjek dan korelasi ini adalah signifi kan untuk lelaki 20-39 tahun sahaja (p < 0.05). Aras CTX-1 tidak berkorelasi dengan antropometri badan subjek (p > 0.05). Secara kesimpulannya, aras PPT dalam kalangan lelaki di Malaysia boleh dipengaruhi oleh faktor umur, kumpulan etnik dan antropometri badan. Faktor-faktor ini seharusnya diambil kira dalam penilaian status kesihatan tulang lelaki berdasarkan aras PPT.
Introduction: In this study, Renal artery (RA) stenosis of Single Stenosed (SS) and Double Stenosed (DS) with the condition of Normal Blood Pressure (NBP) and High Blood Pressure (HBP) were investigated using the aid of Fluid Structure Interaction (FSI) approach. Methods: Numerical analysis of 3D model patient’s specific abdominal aorta with RA stenosis was conducted using FSI solver in software ANSYS 18. Results: The results of velocity profile, pres- sure drop, time average wall shear stress (TAWSS), Oscillatory shear index (OSI) and total deformation of SS and DS with the condition of NBP and HBP were compared in terms of blood flow and structural wall tissue behaviour. The results concluded SS-NBP produced the highest value of velocity profile, TAWSS and OSI parameter compared to the others. Meanwhile, SS-HBP indicates the highest value pressure drop. On the other hand, SS-HBP and DS-HBP have a higher distribution of deformation contour and also maximum VMS compared to SS-NBP and DS-HBP. Conclusion: With the aid of FSI approach, this studied has proven that the existence of SS at RA location has a higher impact on the velocity magnitude, higher pressure drop, higher TAWSS and OSI value compared to the DS case. This is due to a high concentration of pressure acting at the narrow blood vessel of SS compared to DS cases which most of the blood flow will pass to the lower part of abdominal aorta.
Hypertension is a chronic disorder which often entails debilitating cardiovascular and renal complications. Hypertension mostly arises as a complex quantitative trait that is affected by varying combinations of genetic and environmental factors. Secondary hypertension has been encountered with increasing frequency. The common causes of secondary hypertension include renal parenchymal disease, renal artery stenosis, primary aldosteronism, phaeochromocytoma, and Cushing's syndrome. The detection of a secondary cause is of the utmost importance because it provides an opportunity to convert an incurable disease into a potentially curable one. Early identification and treatment will provide a better opportunity for cure, prevent target organ damage, reduce socioeconomic burden and health expenditure associated with drug costs, and improve patients' quality of life. Hence, it is a condition not to be missed.
Phakomatosis pigmentovascularis (PPV) is a rare congenital syndrome characterized predominantly by cutaneous vascular malformations and pigmentary naevi. The most frequently reported form, Type II b, is associated with systemic involvement. Sturge-Weber Syndrome (SWS) with concomitant glaucoma, Klippel-Trenaunay Syndrome (KTS) and naevus of Ota have been frequently described, but there have only been two case reports with asymptomatic renal anomalies.
The evidence presented by the nine cases described in this paper indicates that primary arteritis of the aorta is a single clinico-pathological entity of which Takayashu's syndrome is a part. Different segments of the aorta may be affected resulting in a variety of symptom complexes. In this series, the mode of presentation was hypertension consequent on renal artery stenosis. Early diagnosis is important and surgical treatment is indicated to relieve the hypertension which carries an immediately serious prognosis.
