    Extracorporeal shock wave lithotripsy (ESWL) is accepted as the gold standard treatment for renal stones that are smaller than 2 cm. Recently, retrograde intrarenal surgery (RIRS) has been introduced as another form of treatment. We report our experience in dealing with renal stones smaller than 2 cm using RIRS as the primary treatment and following failed ESWL.

    Caseous lymphadenitis is an infectious disease of almost all animals, particularly small ruminants that are caused by Corynebacterium pseudotuberculosis. The organism causes the formation of suppurative abscesses in superficial and visceral lymph nodes and in visceral organs. This current study was designed to elucidate the clinicopathological responses and PCR detection of the aetiological agent in the vital organs of goats challenged with C. pseudotuberculosis and its immunogenic mycolic acid extract. A total of twelve clinically healthy crossbred Boer female goats were divided into three groups: A, B, and C (four goats per group). Group A was inoculated intradermally with 2 ml of sterile phosphate buffered saline (PBS) pH 7 as a control group. Group B was inoculated intradermally with 2 ml of mycolic acid extract (1 g/ml), while group C was inoculated intradermally with 2 ml of 10⁹ colony-forming unit (cfu) of live C. pseudotuberculosis. The experimental animals were observed for clinical responses for 90 days post-inoculation and the clinical signs were scored according to the severity. The clinical signs observed in this study were temperature, heart rate, respiratory rate, rumen motility, enlargement of lymph nodes, and body condition score. The experimental animals were euthanised and tissue samples from different anatomical regions of the vital organs were collected in 10% buffered formalin, processed, sectioned, and stained with H&E. Results of both C. pseudotuberculosis and mycolic acid treated groups indicated a significant difference (p

    BACKGROUND: This study was conducted to investigate the pathological changes and distribution of B. melitensis in the urinary tract of pregnant goats following acute experimental infection. Six Jamnapari crossbred does in their third trimester of pregnancy were randomly assigned into two groups; Group 1 was uninfected control and Group 2 was inoculated conjunctival with 0.1 mL of the inoculums containing 109 cfu/mL of live B. melitensis. All does were sacrificed 30 days post-inoculation before the kidney, ureter, urinary bladder, urethra and vaginal swab were collected for isolation of B. melitensis. The same tissue samples were fixed in 10% neutral buffered formalin for hematoxylin and eosin, and immunoperoxidase staining.

    RESULTS: None of the goats showed clinical signs or gross lesions. The most consistent histopathology finding was the infiltration of mononuclear cells, chiefly the macrophages with few lymphocytes and occasionally neutrophils in all organs along the urinary tract of the infected goats of Group 2. Other histopathology findings included mild necrosis of the epithelial cells of the renal tubules, congestion and occasional haemorrhages in the various tissues. Kidneys showed the most severe lesions. Immunoperoxidase staining revealed the presence of B. melitensis within the infiltrating macrophages and the epithelium of renal tubules, ureter, urethra and urinary bladder. Most extensive distribution was observed in the urinary bladder. Brucella melitensis was successfully isolated at low concentration (3.4 × 103 cfu/g) in the various organs of the urinary tract and at high concentration (2.4 × 108 cfu/mL) in the vaginal swabs of all infected goats. Although B. melitensis was successfully isolated from the various organs of the urinary tract, it was not isolated from the urine samples that were collected from the urinary bladder at necropsy.

    CONCLUSION: This study demonstrates the presence of low concentrations of B. melitensis in the organs of urinary tract of pregnant does, resulting in mild histopathology lesions. However, B. melitensis was not isolated from the urine that was collected from the urinary bladder.

    The prevalence of glomerulonephritis (GN), especially membranous GN (MGN), changes from time to time. This change may be due to genetic predisposition, environmental factors race, age, and indications for a renal biopsy. This study was conducted to evaluate the distribution and changing patterns of GN by further assessing the prevalence of MGN. A 1000, 123 biopsies were performed from January 2012 to October 2019 in Hospital Serdang and Hospital Kuala Lumpur. Electron microscopy, immunohistochemistry, and clinical presentations were used to differentiate primary and secondary MGN, from which 611 and 457 primary and secondary subjects were diagnosed with primary and secondary GN, respectively. Primary MGN accounts for 13% of all the primary GN, while lupus nephritis (LN) accounts for 44.2% of all secondary GN followed by diabetes mellitus (25.6%). The proportions of primary and secondary MGN were 64.8% and 35.2%, respectively, with a male-to-female ratio of 1:1.1 in favor of females. The renal biopsy obtained from the registry of two prominent hospitals in Malaysia provided valuable prevalence and demonstrated changes in the prevalence of GN in Malaysia. Notwithstanding, immunoglobulin A nephropathy and LN remain the most common causes of primary and secondary GN in Malaysia.

    Aminoglycoside antibiotics are widely employed clinically due to their powerful bactericidal activities, less bacterial resistance compared to beta lactam group and low cost. However, their use has been limited in recent years due to their potential induction of nephrotoxicity. Here we investigate the possibility of reversing nephrotoxicity caused by gentamicin in rat models by using ethanolic crude extract of the medicinal plant Jatropha Mollissima. Nephrotoxic male Wistar rats was obtained by gentamicin antibiotic, which then treated with two doses of J. mollissima crude extract for 3 weeks with monitoring their parameter in weekly base. Our results indicate that J. mollissima crude extract at both doses has strong protection ability against gentamicin nephrotoxicity, most of tested parameters backed to normal values after few days from the administration of the crude extract, which could be due to the antagonized the biochemical action of gentamicin on the proximal tubules of the kidney. The results of histopathologic analysis showed observable improvement in J. mollissima treated groups compared with untreated groups. Our findings suggests the J. mollissima has exceptional nephron protection potentials able to reverse the nephrotoxicity caused by gentamicin antibiotic.

    Recurrent glomerular disease is an important cause of late allograft loss in renal transplant recipients. Immunoglobulin A nephropathy (IgAN) is a leading cause of end-stage renal disease (ESRD) worldwide and its recurrence has been reported in allografts. The present study examined outcomes following renal transplantation (RTX) in 101 patients with ESRD due to biopsy-proven IgAN, in comparison to non-IgA patients, and evaluated the incidence of recurrence. The study population (mean age 34.8 +/- 7.7 years; males 62.2%; Chinese 88.3%) underwent RTX under CsA immunosuppression between November 1984 and December 2004; as two patients underwent retransplantation during the study period, 103 allografts (56.3% cadaveric) were included for retrospective analysis. At time of analysis on 1 January 2005, 78 (75.7%) renal allografts (IgAN RTX) were functioning, of which 51 (49.5%) had normal serum creatinine, 27 (26.2%) had chronic allograft dysfunction, while 25 had graft losses, either due to patient death with functioning grafts (5.8%) or withdrawal to dialysis (18.5%). Persistent microscopic haematuria, not attributable to other causes or proteinuria > 1 g/day occurred in 42.7% and 13.6% of allografts respectively. Of 29 allografts biopsied for evaluation of proteinuria and/or renal dysfunction post-RTX, 8 (27.6%) had IgAN (overall histological recurrence, 7.8%). Of these, three had graft loss due to recurrent IgAN, three had elevated serum creatinine, while two had normal serum creatinine. Overall five and ten year patient survivals for IgAN RTX were 95.3% and 82.2%, and five and ten year actuarial graft survivals were 82.3% and 67.8% respectively. Five and ten year patient and graft survivals for IgAN RTX were not significantly different from that for non-IgAN RTX. In summary, RTX patients with IgAN have a low incidence of documented histological recurrence and recurrence contributing to graft loss occurs in only 2.9%. These results suggest that RTX is an excellent modality of renal replacement therapy in this population.

    PMID: 1890547
    An outbreak of food poisoning resulting in 13 deaths in children occurred in Malaysia during the Chinese Festival of the Nine-Emperor Gods in 1988. The offending food was a Chinese noodle called 'Loh See Fun' (LSF). The source was traced to a factory where a banned food preservative was added to make the LSF. The food poisoning was attributable to aflatoxins and boric acid. The clinical features included vomiting, pyrexia, diarrhoea, abdominal pain, anorexia, giddiness, seizures, and eventual coma. Initially, many presented with a Reye-like syndrome. Eleven post-mortem examinations were performed. The pathological findings included extensive coagulative necrosis of the liver with proliferative 'ductal/ductular metaplasia of the hepatocytes'. Giant cell formation, central vein sclerosis, bile stasis, and steatosis were also noted. There was presence of acute tubular necrosis, superficial upper gastrointestinal erosions, and ensuing encephalopathy. The eventual cause of death is acute hepatic and renal failure.

  8. Emerging and re-emerging epidemic encephalitis: a tale of two viruses
    Wong KT
    Neuropathol. Appl. Neurobiol., 2000 Aug;26(4):313-8.
    PMID: 10931364
    Two major epidemics of viral encephalitis occurred in Asia in 1997 and 1998. The first was a re-emergence of neurovirulent strains of enterovirus 71, which caused severe encephalomyelitis in children in Malaysia, Taiwan and Japan, on a background of hand, foot and mouth disease. Necropsy studies of patients who died of enterovirus 71 infection showed severe perivascular cuffing, parenchymal inflammation and neuronophagia in the spinal cord, brainstem and diencephalon, and in focal areas in the cerebellum and cerebrum. Although no viral inclusions were detected, immunohistochemistry showed viral antigen in the neuronal cytoplasm. Inflammation was often more extensive than neuronal infection, suggesting that other factors, in addition to direct viral cytolysis, may be involved in tissue damage. The second epidemic of viral encephalitis was the result of a novel paramyxovirus called Nipah, which mainly involved pig handlers in Malaysia and Singapore. Pathological evidence suggested that the endothelium of small blood vessels in the central nervous system was particularly susceptible to infection. This led to disseminated endothelial damage and syncytium formation, vasculitis, thrombosis, ischaemia and microinfarction. However, there was also evidence of neuronal infection by the virus and this may also have contributed to the neurological dysfunction in Nipah encephalitis. Some patients who seemed to recover from the acute symptoms have been re-admitted with clinical findings suggestive of relapsing encephalitis. As these two epidemics indicate, the emergence and re-emergence of viral encephalitides continue to pose considerable challenges to the neuropathologist, in establishing the diagnosis and unravelling the pathogenesis of the neurological disease.

    PMID: 20979946
    This review of 2,586 renal biopsies over the past 3 decades in Singapore documents the changing pattern of glomerulonephritis (GN) from that of a third world country to that of a developed nation. In the 1st decade, mesangial proliferative glomerulonephritis was the most common form of primary GN, just as it was in the surrounding Asian countries. In the 2nd decade, the prevalence of mesangial proliferative GN decreased with a rise in membranous, GN which is also seen in China and Thailand. In the 3rd decade, there was a dramatic increase in focal sclerosing glomerulosclerosis. This increase reflects aging and obesity in keeping with more developed countries like Australia, India, Thailand and the United States of America. IgA nephritis remains the most common GN. Apart from the geographical influence, other socioeconomic factors play a significant role in the evolution of the renal biopsy pattern. Mesangial proliferative GN remains prevalent in many Asian countries, but in Singapore the prevalence is decreasing just as it is in Japan, Korea and Malaysia. Worldwide, the prevalence of focal sclerosing glomerulosclerosis continues to increase in many countries.

  11. Fulltext A KLF6-driven transcriptional network links lipid homeostasis and tumour growth in renal carcinoma
    Syafruddin SE, Rodrigues P, Vojtasova E, Patel SA, Zaini MN, Burge J, et al.

    Transcriptional networks are critical for the establishment of tissue-specific cellular states in health and disease, including cancer. Yet, the transcriptional circuits that control carcinogenesis remain poorly understood. Here we report that Kruppel like factor 6 (KLF6), a transcription factor of the zinc finger family, regulates lipid homeostasis in clear cell renal cell carcinoma (ccRCC). We show that KLF6 supports the expression of lipid metabolism genes and promotes the expression of PDGFB, which activates mTOR signalling and the downstream lipid metabolism regulators SREBF1 and SREBF2. KLF6 expression is driven by a robust super enhancer that integrates signals from multiple pathways, including the ccRCC-initiating VHL-HIF2A pathway. These results suggest an underlying mechanism for high mTOR activity in ccRCC cells. More generally, the link between super enhancer-driven transcriptional networks and essential metabolic pathways may provide clues to the mechanisms that maintain the stability of cell identity-defining transcriptional programmes in cancer.

  12. Fulltext Efficacy of carbazole alkaloids, essential oil and extract of Murraya koenigii in enhancing subcutaneous wound healing in rats
    Nagappan T, Segaran TC, Wahid ME, Ramasamy P, Vairappan CS
    Molecules, 2012 Dec 05;17(12):14449-63.
    PMID: 23519245 DOI: 10.3390/molecules171214449
    The traditional use of Murraya koenigii as Asian folk medicine prompted us to investigate its wound healing ability. Three carbazole alkaloids (mahanine (1), mahanimbicine (2), mahanimbine (3)), essential oil and ethanol extract of Murraya koenigii were investigated for their efficacy in healing subcutaneous wounds. Topical application of the three alkaloids, essential oil and crude extract on 8 mm wounds created on the dorsal skin of rats was monitored for 18 days. Wound contraction rate and epithelialization duration were calculated, while wound granulation and collagen deposition were evaluated via histological method. Wound contraction rates were obvious by day 4 for the group treated with extract (19.25%) and the group treated with mahanimbicine (2) (12.60%), while complete epithelialization was achieved on day 18 for all treatment groups. Wounds treated with mahanimbicine (2) (88.54%) and extract of M. koenigii (91.78%) showed the highest rate of collagen deposition with well-organized collagen bands, formation of fibroblasts, hair follicle buds and with reduced inflammatory cells compared to wounds treated with mahanine (1), mahanimbine (3) and essential oil. The study revealed the potential of mahanimbicine (2) and crude extract of M. koenigii in facilitation and acceleration of wound healing.

  15. Protective effect of isosteviol sodium against LPS-induced multiple organ injury by regulating of glycerophospholipid metabolism and reducing macrophage-driven inflammation
    Wang S, Tan KS, Beng H, Liu F, Huang J, Kuai Y, et al.
    Pharmacol Res, 2021 Oct;172:105781.
    PMID: 34302975 DOI: 10.1016/j.phrs.2021.105781
    Sepsis is a severe inflammatory disorder that can lead to multiple organ injury. Isosteviol sodium (STV-Na) is a terpenoid derived from stevioside that exerts anti-inflammatory, antioxidant and antiapoptotic activities. However, the influence of STV-Na on sepsis remains unknown. Here, we assessed the potential effects of STV-Na on sepsis and multiple organ injury induced by lipopolysaccharide (LPS). We found that STV-Na increased the survival rate of mice treat with LPS, significantly improved the functions of the heart, lung, liver, and kidney, reduced the production of inflammatory cytokines and decreased macrophage infiltration. Moreover, Multiorgan metabolomics analysis demonstrated that glutathione metabolism, purine metabolism, glycerophospholipid metabolism and pantothenate and CoA biosynthesis, were significantly altered by STV-Na. This study provides novel insights into the metabolite changes of multiple organ injury in septic mice, which may help characterize the underlying mechanism and provide an improved understanding of the therapeutic effects of STV-Na on sepsis.

    PMID: 22250665 DOI: 10.3109/0886022X.2011.647302
    BACKGROUND:
    Type 2 diabetes mellitus (T2DM) is reportedly the leading cause of end-stage renal disease (ESRD) worldwide. However, non-diabetic renal diseases (NDRD) are not uncommon among T2DM patients with renal involvement. Our study aimed to examine the prevalence of NDRD in T2DM and clinical markers for diabetic nephropathy (DN) and NDRD and to determine the role of renal biopsy in T2DM patients and its impact on clinical practice.

    METHODS:
    We conducted a retrospective analysis of T2DM patients in whom renal biopsies were performed from January 2004 to March 2008 (n = 110).

    RESULTS:
    Biopsy results were divided into three groups: group I/pure DN (62.7%), group II/isolated NDRD (18.2%), and group III/mixed lesions (19.1%). The causes of NDRD in decreasing order of frequency were acute interstitial nephritis, glomerulonephritides, hypertensive renal disease, and acute tubular necrosis. Significant clinical markers for DN are presence of diabetic retinopathy and longer duration of diabetes. For NDRD, useful clinical markers include the presence of acute renal failure and microscopic hematuria. In the DN subgroup, Indians had significantly shorter duration of diabetes on biopsy compared with Malays and Chinese.

    CONCLUSIONS:
    NDRD is prevalent in T2DM patients, and given its potentially treatable nature, renal biopsy should be considered in T2DM patients with nephropathy, especially in those with atypical features.

  17. Clinical and pathological manifestations of human henipavirus infection
    Wong KT, Tan CT
    Curr. Top. Microbiol. Immunol., 2012;359:95-104.
    PMID: 22427144 DOI: 10.1007/82_2012_205
    The clinicopathological features of human Nipah virus and Hendra virus infections appear to be similar. The clinical manifestations may be mild, but if severe, includes acute encephalitic and pulmonary syndromes with a high mortality. The pathological features in human acute henipavirus infections comprise vasculopathy (vasculitis, endothelial multinucleated syncytia, thrombosis), microinfarcts and parenchymal cell infection in the central nervous system, lung, kidney and other major organs. Viral inclusions, antigens, nucleocapsids and RNA are readily demonstrated in blood vessel wall and numerous types of parenchymal cells. Relapsing henipavirus encephalitis is a rare complication reported in less than 10% of survivors of the acute infection and appears to be distinct from the acute encephalitic syndrome. Pathological evidence suggests viral recrudescence confined to the central nervous system as the cause.

  20. Fulltext Protecting mechanism of Swietenia macrophylla ethanol extract nanoparticle on streptozotocin induced renal damage in rat
    Kurnijasanti R, Wardani G, Mustafa MR, Sudjarwo SA
    Open Vet J, 2023 Dec;13(12):1623-1630.
    PMID: 38292712 DOI: 10.5455/OVJ.2023.v13.i12.12
    BACKGROUND: Hyperglycemia increases reactive oxygen species (ROS), which contributes to diabetic complications such as kidney cell damage. Antioxidant administration could inhibit ROS and kidney cell damage commonly seen in hyperglycemia.

    AIM: We want to demonstrate that the antioxidant properties of Swietenia macrophylla ethanol extract nanoparticles can prevent kidney cell damage brought on by streptozotocin (STZ) in the current investigation.

    METHODS: This study employs high-energy ball milling to produce nanoparticles from S. macrophylla extract. Additionally, dynamic light scattering (DLS) is utilized to characterize the nanoparticle sizes of the S. macrophylla ethanol extract. Five groups, each consisting of 8 rats, were formed from 40 rats. Control rats received distilled water, the diabetic rats were administered STZ injections, while S. macrophylla rats were given S. macrophylla extract nanoparticles orally and STZ injection. After the trial, blood from a rat was drawn intracardially to check the levels of blood urea nitrogen (BUN) and creatinine. The levels of superoxide dismutase (SOD), glutathione peroxidase (GPx), and malondialdehyde (MDA) were then assessed in kidney tissue samples. Histological alterations were evaluated in kidney section samples.

    RESULTS: A DLS analysis estimated the size of the S. macrophylla ethanol extract nanoparticles to be about 91.50 ± 23.06 nm. BUN and creatinine levels were significantly raised after STZ treatment. STZ significantly decreased SOD and GPx levels in kidney tissue while raising MDA levels (p < 0.05). Swietenia macrophylla ethanol extract nanoparticle caused the decreased levels of BUN and creatinine in blood to normal levels (p < 0.05), indicating that S. macrophylla ethanol extract prevented the STZ-induced kidney cell damage. Additionally, S. macrophylla nanoparticles significantly raise GPx and SOD levels in kidney tissue while lowering MDA levels (p < 0.05). These actions are thought to have prevented kidney histological alterations (degeneration and necrosis) in diabetic rats.

    CONCLUSION: According to these results, the anti-oxidative stress properties of S. macrophylla nanoparticles make them potentially effective nephroprotective therapies for STZ-induced kidney cell damage.
