  1. Social and cultural aspects of organ donation in Asia
    Woo KT
    Ann Acad Med Singap, 1992 May;21(3):421-7.
    PMID: 1416796
    In Asian countries, it is more difficult to obtain cadaver kidneys for renal transplantation because of certain socio-cultural beliefs and customs. The issues affecting living related kidney donation are more social than cultural. This is due to the web of family pressures and personal conflicts for both donor and recipient surrounding the donation. Important misconceptions and fears are: fear of death, the belief that removal of organ violates sanctity of decreased, concern about being cut up after death, desire to be buried whole, dislike of idea of kidneys inside another person, wrong concept of brain death, and the idea of donation being against religious conviction. In Singapore, with the introduction of the Human Organ Transplant Act (HOTA) in 1988, the number of cadaveric transplants have increased, including those from the Medical Therapy Act (MTA). HOTA and education have played pivotal roles in bringing about an increased yield of cadaveric kidneys. With the availability of living unrelated donor (LUD) transplants in India, our living related donor (LRD) transplant programme has suffered, because patients would rather buy a kidney from overseas than get a relative to donate one. Patients are also going to China for overseas cadaveric transplants where the kidneys come from executed convicts. People in countries like Hong Kong, Japan and the Philippines share the same Asian tradition of not parting with their organs after death. Muslim countries like Malaysia require the deceased to have earlier pledged his kidneys for donation prior to death before they can be harvested for transplantation at death.

  2. Medical aspects of haematuria
    Suleiman AB
    Ann Acad Med Singap, 1987 Apr;16(2):238-9.
    PMID: 3688799
    Haematuria is always a significant finding that requires proper evaluation, and investigations may need to be initiated based on an adequate history. A careful urine microscopy of the urine using phase contrast microscopy is essential, and may predict the source of the haematuria based on red cell morphology, and point the direction that appropriate investigation should take. Infection tumours, obstruction; and calculi account for most cases of gross haematuria in adults. In paediatric patients, the causes of gross haematuria are readily apparent in half of the cases, but further investigations are necessary in the other half. All cases of haematuria require prompt evaluation and appropriate investigations to ensure correct and early treatment.

  3. Spectrum of nocardiosis in renal patients
    Kong NC, Morad Z, Suleiman AB, Cheong IK, Lajin I
    Ann Acad Med Singap, 1990 May;19(3):375-9.
    PMID: 2393240
    Nocardiosis is an increasingly recognised opportunistic infection in immunologically incompetent hosts but diagnosis is often delayed. Between December 1975 to October 1988, our two Nephrology Units have encountered five cases of nocardiosis occurring in two post-renal transplant patients, two patients with systemic lupus erythematous (SLE) and one patient with mesangiocapillary glomerulo--nephritis. All were on immunosuppressants at the time. The first three patients presented with predominant pulmonary disease and were cured by combined trimethoprim-sulphamethoxazole (cotrimoxazole) and doxycycline therapy. The patient with limited skin involvement responded to cotrimoxazole alone. However, the last patient with lymphocutaneous disease initially responded to cotrimoxazole (+ chloramphenicol) but developed acute-on-chronic renal failure and relapsed with dose reduction of cotrimoxazole. Alternative treatment with amikacin and doxycycline was instituted with good response. We shall review potential clues that may suggest the diagnosis of nocardiosis and discuss other effective antimicrobial agents.

  4. Morphological patterns of glomerular disease in renal biopsies from 1000 Malaysian patients
    Prathap K, Looi LM
    Ann Acad Med Singap, 1982 Jan;11(1):52-6.
    PMID: 7073229
    Adequately biopsied renal tissue received in the Department of Pathology, University Hospital, Kuala Lumpur from 1,000 consecutive Malaysian patients during an eleven year period between 1970 and 1981 was reviewed. The youngest patient was 6 days old and the oldest 80 years. Both sexes were equally represented. The majority of the patients were Chinese (71%) with Malays and Indians comprising most of the remainder. Over half the patients (50.4%) presented with the nephrotic syndrome. Other modes of presentation included systemic lupus erythematosus, proteinuria and haematuria separately or in combination and hypertension. Minimal change (25.7%) and proliferative glomerulonephritis (24.8%) were present in about equal numbers and together accounted for over half of the cases (50.5%). Lupus nephritis was the third most common diagnosis (18.4%). In addition, there were patients with focal glomerulonephritis (5.4%), membranous glomerulonephritis (5.5%), Berger's disease (5.8%), amyloidosis (0.6%) and end stage renal disease (4.0%).

  5. Clinical review of acute renal failure: a 5-year experience at Kuala Lumpur
    Suleiman AB
    Ann Acad Med Singap, 1982 Jan;11(1):32-5.
    PMID: 7073225
    Over a five year period, 184 patients were treated for acute renal failure. Uraemia was usually treated by peritoneal dialysis, and haemodialysis was reserved for post surgical and hypercatabolic patients. The overall mortality was 33.2% and was highest among surgical patients. These results were similar to previous reports. Peritoneal dialysis was usually effective in controlling uraemia. Uncontrolled sepsis remains a major problem, and septicaemia and gastrointestinal bleeding were adverse factors affecting the outcome. The combination of septicaemia and gastrointestinal bleeding commonly led to a fatal outcome.

  6. Tuberculosis in living related donor renal transplant recipients
    Suleiman AB, Musa Z, Morad Z
    Ann Acad Med Singap, 1988 Jul;17(3):454-6.
    PMID: 3064705
    Ten out of 237 patients who underwent renal transplantation between 1975 and October 1986 developed tuberculosis. Most patients presented with vague symptoms, and typical symptoms commonly associated with tuberculosis were not common. Six had positive urine cultures. One patient had positive sputum and urine cultures and one had positive sputum and cerebrospinal fluid cultures for tuberculosis. In this last patient cryptococcus was also cultured from the sputum and CSF. Nine of the 10 patients responded well to antituberculosis therapy and was cured of the infection. The patient with associated cryptococcal infection died 2 months after presentation. Side effects of antituberculous therapy was minimal and easily resolved on stopping the offending drug.

  7. Renal Transplant Outcomes in Spousal and Living-Related Donors in Malaysia
    Guad RM, Ng KP, Lim SK, Hirayama K, Eng HS, Wan Md Adnan WAH
    Ann Acad Med Singap, 2019 Dec;48(12):403-411.
    PMID: 32112065
    INTRODUCTION: Studies have shown that a compatible human leukocyte antigen (HLA) match can confer a favourable effect on graft outcomes. We examined the outcomes of HLA matching in renal transplant donors in Malaysia.

    MATERIALS AND METHODS: A total of 140 patients who had compatible ABO blood type with negative T-cell lymphocytotoxicity crossmatch were included in the study and 25% of them were spousal transplant donors. No remarkable differences in acute rejection rate, graft survival, patient survival and serum creatinine level were observed between the spousal and living-related donor groups.

    RESULTS: The spousal donor group had a higher degree of HLA mismatch than the living-related donor group. HLA-A mismatch was associated with increased rejection risk at 6 months (odds ratio [OR], 2.75; P = 0.04), 1 year (OR, 2.54; P = 0.03) and 3 years (OR, 3.69; P = 0.001). It was also observed in the deleterious effects of HLA-B and HLA-DQ loci when the number of antigen mismatches increased. The risk was 7 times higher in patients with ≥1 mismatch at HLA-A, HLA-B and HLA-DR loci than those who did not have a mismatch at these loci at 6 months (P = 0.01), 1 year (P = 0.03) and 3 years (P = 0.003).

    CONCLUSION: A good match for HLA-A, HLA-B, HLA-DR and HLA-DQ can prevent acute rejection risk in renal transplant patients. Consequently, spousal donor transplants could be a safe intervention in renal patients.

    Sreenevasan G
    Ann R Coll Surg Engl, 1974 Jul;55(1):3-12.
    PMID: 4845653
    Bilateral renal calculi were present in 114 (10.7%) of 1,070 cases of proved urinary calculus admitted to the Urological Department of the General Hospital, Kuala Lumpur, during the period November 1968-May 1973. The management of bilateral renal calculi is discussed with reference to the first 100 cases in this series. The introduction of renography has greatly facilitated the decision as to which kidney should be operated on first. The management of patients with and without uraemia is discussed and the use of the modified V and V-Y incisions for the removal of staghorn calculi is described. Complications and results are briefly reviewed.

    Renal cell carcinoma (RCC) has been shown to cause venous migration in the inferior vena cava (IVC). It is very important for preoperative imaging to be carried out, which will decide the surgical approach for the patient. Duplication of IVC is an uncommon anomaly. We report a case of RCC with duplication of IVC.

  10. Do Family Members of Dialysis Patients Have a Positive Attitude Toward Organ Donation?
    Tumin M, Tafran K, Zakaria RH, Satar NM, Ng KP, Lim SK
    Ann. Transplant., 2015 Dec 22;20:752-6.
    PMID: 26690676 DOI: 10.12659/aot.894427
    BACKGROUND: Malaysia, which currently uses the informed consent system (ICS), is suffering from a severe shortage of organs for transplantation. Family members of dialysis patients (FMDPs) are expected to have a positive attitude toward deceased organ donation (DOD) because they have a close relative in need of a kidney donation. This study explores FMDPs' attitude toward DOD under the ICS and the presumed consent system (PCS).

    MATERIAL/METHODS: The attitude of 350 FMDPs toward DOD under the ICS and PCS were sought between June and October 2013 in 3 dialysis institutions in Kuala Lumpur, Malaysia.

    RESULTS: Under the ICS, 6.6% of respondents were registered donors, 6.6% were ready to register at the time of the survey, 38.6% were willing to donate but not ready to register at the time of the survey, and 48.2% were unwilling to donate organs upon death. If the PCS were implemented, 57.7% of respondents (28.7% of the willing donors and 88.7% of the unwilling respondents) stated that they would officially object to organ donation.

    CONCLUSIONS: FMDPs' attitude toward DOD is not more positive or significantly better than that of the general public (based on earlier studies). The PCS may increase the number of donors, but it may also worsen the attitude of FMDPs toward DOD. Strategies aiming to promote DOD in Malaysia should be revised, and should perhaps be focused on enhancing trust of the medical system.

  13. Non-steroid receptor-mediated antiproliferative activity of styrylpyrone derivative in human breast cancer cell lines
    Pihie AH, Stanslas J, Din LB
    Anticancer Res, 1998 May-Jun;18(3A):1739-43.
    PMID: 9673398
    The antiproliferative activity of a styrylpyrone derivative (SPD) plant extract, was studied in three different human breast cancer cell lines in culture, and was compared with tamoxifen. The number of living cells was evaluated by Methylene Blue staining technique. SPD showed strong antiproliferative activity in estrogen receptor (ER) and progestin receptor (PgR) positive MCF-7 cells (EC50 = 6.30 x 10(-7) M) and receptor-negative MDA-MB-231 (EC50 = 5.62 x 10(-7) M), but it partially inhibited the high progestin receptor positive T47D cells (EC50 = 1.58 x 10(-6) M). Whereas tamoxifen, a nonsteroidal antiestrogen exhibited strong inhibition on MCF-7 cells (EC50 = 1.41 x 10(-6) M) and partial inhibition on T47D cells (EC50 = 2.5 x 10(-6) M), but did not affect the MDA-MB-231 cells in the concentration range 0.1 nM-1 microM (EC50 = 5.01 microM). At the same concentration range SPD and tamoxifen did not inhibit the proliferation of normal human liver cell line CCL 13 and normal bovine kidney MDBK; whereas adriamycin, a common chemotherapy drug for the treatment of advance cancer, caused 95% inhibition at 10(-6) M. Competitive binding studies showed SPD had no ability to inhibit the binding of [3H]estradiol and [3H]progesterone to ER and PgR, respectively but, tamoxifen exhibited affinity for ER. Therefore, it can be concluded that the antiproliferative activity of SPD was selective towards breast cancer cell lines and not mediated by ER or PgR.

  15. Proteomics and detection of uromodulin in first-time renal calculi patients and recurrent renal calculi patients
    Wai-Hoe L, Wing-Seng L, Ismail Z, Lay-Harn G
    Appl Biochem Biotechnol, 2009 Oct;159(1):221-32.
    PMID: 19145410 DOI: 10.1007/s12010-008-8503-x
    Renal calculi disease or known as kidney stone disease is the most common urological disorder in both men and women, although it is more prevalent in men. The lifetime chance for an individual to develop renal calculi is approximately 10% whereas the risk of recurrence in a 10-year period is 74%. Therefore, a diagnostic tool for screening or detecting renal calculi is greatly needed. In this study, we analyze urinary protein profiles from patients with renal calculi for the first time (RC), healthy subjects (HS), and patients with recurrent renal calculi (RRC) to identify a biomarker for detecting the disease. Urinary proteins were isolated by salt precipitation and the proteins resolved by SDS-PAGE. Target proteins were analyzed with LC/MS/MS. Thirty-two proteins were identified from healthy subjects and patients. Uromodulin was the most abundant urinary protein in HS but was a very faint band if detected at all from those that formed renal calculi for the first time (p < 0.05). Yet the excreted levels of urinary uromodulin in RRC were similar to those of the HS suggesting that uromodulin is a reliable biomarker for only RC. In addition, a few immunoglobulins that were commonly found in the urine of both RC and RRC, which include Ig alpha heavy chain 1, Ig gamma-2 c region, Ig gamma-3 heavy chain disease protein, Ig heavy chain variable region, Ig heavy constant region gamma 4, and Ig heavy chain. Ig heavy chain Fab frag and antibody a5b7 chain B may serve as potential biomarkers for renal calculi disease.

    PMID: 27618413
    Virgin coconut oil, rich in antioxidants, was shown to attenuate hypertension. This study aimed to investigate the effects of virgin coconut oil on blood pressure and related parameters in kidneys in rats fed with 5-times-heated palm oil (5HPO). Thirty-two male Sprague-Dawley rats were divided into 4 groups. Two groups were fed 5HPO (15%) diet and the second group was also given virgin coconut oil (1.42 mL/kg, oral) daily for 16 weeks. The other 2 groups were given basal diet without (control) and with virgin coconut oil. Systolic blood pressure was measured pre- and post-treatment. After 16 weeks, the rats were sacrificed and kidneys were harvested. Dietary 5HPO increased blood pressure, renal thiobarbituric acid reactive substance (TBARS), and nitric oxide contents, but decreased heme oxygenase activity. Virgin coconut oil prevented increase in 5HPO-induced blood pressure and renal nitric oxide content as well as the decrease in renal heme oxygenase activity. The virgin coconut oil also reduced the elevation of renal TBARS induced by the heated oil. However, neither dietary 5HPO nor virgin coconut oil affected renal histomorphometry. In conclusion, virgin coconut oil has a potential to reduce the development of hypertension and renal injury induced by dietary heated oil, possibly via its antioxidant protective effects on the kidneys.

    Appl Radiat Isot, 1999 Jun;50(6):989-94.
    PMID: 10355102
    This paper focuses on the evaluation of the k0 method of instrumental neutron activation analysis in biological materials. The method has been applied in multielement analysis of human hair standard reference materials from IAEA, No. 085, No. 086 and from NIES (National Institute for Environmental Sciences) No. 5. Hair samples from people resident in different parts of Malaysia, in addition to a sample from Japan, were analyzed. In addition, human kidney stones from members of the Malaysian population have been analyzed for minor and trace elements. More than 25 elements have been determined. The samples were irradiated in the rotary rack (Lazy Susan) at the TRIGA Mark II reactor of the Malaysian Institute for Nuclear Technology and Research (MINT). The accuracy of the method was ascertained by analysis of other reference materials, including 1573 tomato leaves and 1572 citrus leaves. In this method the deviation of the 1/E1+ alpha epithermal neutron flux distribution from the 1/E law (P/T ratio) for true coincidence effects of the gamma-ray cascade and the HPGe detector efficiency were determined and corrected for.

    Renal cancer is a rare occurrence in all adult malignancies, and renal cell carcinoma (RCC) is the most common type. Due to its aggressive behaviour and high tendency for metastasis, manifestation of RCC varies, often with non-urologic features or symptoms from metastatic sites. Metastatic RCC to the head and neck region is rare particularly to the tongue are extremely rare. We report an elderly lady who presented with recurrent tongue mass metastasis from RCC, a rare cancer with even rarer metastatic site.

    Haemodialysis associated amyloidosis (HAA) is a complication of long-term haemodialysis caused by deposition of β2-microglobulin in tissues that most often presents clinically at osteoarticular sites. However, in very rarecircumstances, patients do present initially with oral manifestations of HAA. In a normally functioning kidney, β2-microglobulin is cleared by glomerular filtration and is catabolized in the proximal tubules. This article describes a patient with oral manifestation of haemodialysis associated amyloidosis with an unusual presenting complaint of lingual dysaesthesia.

    PMID: 28024836 DOI: 10.1016/j.abb.2016.12.008
    We hypothesized that higher blood pressure in males than females could be due to testosterone effects on aquaporin (AQP) expression in kidneys.

    METHODS: Orchidectomized adult male Sprague-Dawley (SD) rats received seven days subcutaneous testosterone treatment (125 μg/kg/day or 250 μg/kg/day), with or without flutamide or finasteride. Following completion of treatment, MAP was determined in rats under anaesthesia via carotid artery cannulation. In another cohort of rats, kidneys were removed following sacrifice and AQP-1, 2, 3, 4, 6 and 7 protein and mRNA levels were determined by Western blotting and Real-time PCR respectively. Distribution of AQP subunits' protein in the nephrons were visualized by immunofluorescence.

    RESULTS: Testosterone caused MAP, AQP-1, 2, 4, 6 and 7 protein and mRNA levels in kidneys to increase while AQP-3 protein and mRNA levels in kidneys to decrease (p
