Renal Doppler Indices in Children with Nephrotic Syndrome: Findings from a Tertiary Hospital in Nigeria

Summary: The resistive and pulsatility indices are known tools for assessing renal function in kidney diseases, especially in proteinuric conditions like Paediatric Nephrotic syndrome (NS) which is a glomerular disease. However, there is a limited knowledge in the use of Doppler Resistive and pulsatility indices in the management of this disease condition. This was a case control study involving 53 cases and 57 controls. The Doppler parameters, resistive index (RI) and pulsatility index (PI) of the renal interlobar arteries were determined for the upper, middle, and lower poles bilaterally for both controls and cases. The mean RI on the right and left were 0.59 ± 0.06 and 0.58 ± 0.06 respectively for the NS cases whereas for the controls it was 0.61 ± 0.05 and 0.60 ± 0.04 on the right and left respectively. The mean PI on the right and left measured 0.96 ± 0.16 and 0.94 ± 0.15 respectively for the NS cases while that for the control cases measured 0.98 ± 0.13.and 0.95 ± 0.12 on the right and left respectively. Although, the interlobar arteries mean RIs were generally less than that for the controls, but only the left middle pole showed statistically significant mean difference (p= 0.004). There was also statistically significant mean difference (p= 0.048) between the cases and controls in the left middle pole PI. However, no correlation was found when the renal RI and PI are compared with the serum albumin and creatinine. Although there was no statistical significance between the mean RI and PI of the NS cases and controls, except in the left middle pole RI, it is recommended that Doppler ultrasound should still be part of management of Nephrotic syndrome patients especially those who have developed end stage renal disease in order to monitor their renal function.Keywords: Paediatric, Nephrotic Syndrome, Renal, Resistive Index, Pulsatility Inde

Abdominal ultrasonography in HIV/AIDS patients in southwestern Nigeria

<p>Abstract</p> <p>Background</p> <p>Though the major target of the HIV-virus is the immune system, the frequency of abdominal disorders in HIV/AIDS patients has been reported to be second only to pulmonary disease. These abdominal manifestations may be on the increase as the use of antiretroviral therapy has increased life expectancy and improved quality of life. Ultrasonography is an easy to perform, non invasive, inexpensive and safe imaging technique that is invaluable in Africa where AIDS is most prevalent and where sophisticated diagnostic tools are not readily available. Purpose: To describe the findings and evaluate the clinical utility of abdominal ultrasonography in HIV/AIDS patients in Ibadan, Nigeria</p> <p>Methods</p> <p>A Prospective evaluation of the abdominal ultrasonography of 391 HIV-positive patients as well as 391 age and sex-matched HIV-negative patients were carried out at the University College Hospital, Ibadan.</p> <p>Results</p> <p>Of the 391 cases studied, 260 (66.5%) were females; the mean age was 38.02 years, (range 15–66 years). The disease was most prevalent in the 4th decade with an incidence of 40.4%. Compared with the HIV-negative individuals, the HIV+ group of patients had a significantly higher proportion of splenomegaly (13.5% vs. 7.7%; p < 0.01), lymphadenopathy (2.0% vs. 1.3%; p < 0.70), and renal abnormalities (8.4% vs. 3.8%; p < 0.02). There were no differences in hepatic and pancreatic abnormalities between the HIV+ and HIV- groups. There were significantly fewer gallstones in the HIV+ group (1.4% vs. 5.1%; p < 0.01).</p> <p>Conclusion</p> <p>AIDS is a multi-systemic disease and its demographic and clinical pattern remains the same globally. Ultrasonography is optimally suited for its clinical management especially in Africa. Its accuracy and sensitivity may be much improved with clinico-pathologic correlation which may not be readily available in developing countries; further studies may provide this much needed diagnostic algorithms.</p

Carotid body chemodectoma and carotid aneurysm–a case illustration of diagnostic problems

Carotid body tumours are very rare and occur at the carotid artery bifurcation between the internal and external carotid arteries. The carotid bodies are reddish brown ellipsoid structures, lying embedded in the adventitial of the carotid artery bifurcation. The usual presentation is a slow growing mass at the angle of mandible. Sometimes these tumours are confused with enlarged lymph nodes, brachial cysts, salivary glands, neurofibromas and carotid aneurysms especially. Thus carotid body tumours can be a diagnostic challenge for a clinician resulting in patients being consequently subjected to unwise attempts at biopsy or explorative surgery.We present the diagnostic problems of carotid body tumour and carotid aneurysm as seen in a Nigerian African.Keywords: carotid body, chemodectoma, carotid aneurysmNigerian Journal of Otorhinolaryngology Vol. 2(2) 2005: 81-8
