ABSTRACT
Introduction: In recent years, there has been a rise in chronic kidney disease (CKD), and it has been estimated that by 2040, CKD will be the fifth most common cause of death globally. In addition to diabetes, hypertension, obesity, hyperlipidemia, and nonalcoholic fatty liver disease commonly associated with CKD, exposure to various toxins as a result of pollution or industrial disasters is also discussed as a cause for multi-organ pathology including kidneys. Although few cytogenetic studies were undertaken to assess the genetic damage in survivors of the disaster, no studies are available on the cytogenetic damage of toxic-gas exposed population having CKD. Therefore, the present multi-group cross-sectional study was undertaken to assess the independent role of CKD as well as toxic gas exposure on cytogenetics. Methods: The cytogenetic alterations were evaluated through chromosomal aberration analysis and micronuclei assay. The study included 608 study participants divided into four groups on the basis of history of exposure to the leaked gas and presence or absence of CKD. Results: The results of the study showed no statistically significant difference in cytogenetic damage between gas-exposed and non-exposed patients of CKD, whereas significantly higher cytogenetic damage was observed among gas-exposed participants having CKD compared to gas-exposed participants free from CKD, suggesting that cytogenetic changes could be due to CKD itself. Conclusions: Thus, to conclude, the cytogenetic alterations observed in the study can be partly attributed to the disease itself.
ABSTRACT
Introduction: Xanthogranulomatous inflammation is a rare nonneoplastic and chronic inflammatory process, characterized by proliferation of foamy macrophages resulting in damage and necrosis of the affected tissue. Involvement of the testis/epididymis by the disease is a rare event. Methods: A case series of four male patients diagnosed with xanthogranulomatous epididymitis/orchitis (XGEO) at our institute was reviewed. In addition, a systematic review of XGEO was carried out using PRISMA Guidelines 2020. Twenty-nine articles describing 38 patients of XGEO were included in the study. Results: XGEO usually has a subacute or chronic presentation and affects male individuals in the 5th or 6th decades of life. The disease is also known to occur in the pediatric age group. The patients present with swelling, tenderness, or pain in the scrotal region. Bilateral involvement has also been documented. Thirty patients were known to have one or more causal risk factors including diabetes mellitus (23.7%), spinal cord injury/neuropathic bladder (7.9%), prostatectomy (7.9%), trauma (4.1%), and transurethral resection of prostate procedure (4.1%). Complications observed were scrotal fistula, adhesions, and abscess formation. Radiological features reported are nonspecific and include heterogeneous echotexture, hypoechoic areas, and/or scrotal wall collections. Bacterial microorganisms isolated from the affected tissue demonstrated the presence of Escherichia coli, Pseudomonas aeruginosa, and Staphylococcus aureus. Histological subtypes of XGEO are diffuse and focal. In the diffuse subtype, which is more common, there is extensive parenchymal destruction by inflammatory process accompanied by widespread ischemic necrosis. Conclusion: The mainstay of treatment in XGEO cases is surgical excision preferably orchidectomy. Conservative management has been attempted in young individuals and in patients with focal XGEO, but there is limited supporting evidence. We present data of four cases along with detailed systematic review of the disease examining its clinicopathological behavior and associated risk factors followed by operative approach.
