RESUMO
BACKGROUND: The number of skin cancer cases and related deaths continues to increase worldwide, including in Portugal. The lack of efficient health care leaves the southern Portuguese population at risk of presenting skin lesions at later stages. An initiative for skin cancer screening and medical care follow-up was created by the nonprofit organization Liga Portuguesa Contra o Cancro - Núcleo Regional do Sul (LPCC-NRS). METHODS: Information was gathered from 4,398 participants in several Southern Portugal regions, from January 2021 to July 2022. Descriptive and lesion risk statistical analyses were applied. RESULTS: Participants' characteristics were described, and risk assessment was performed differentially between premalignant (n = 577) and malignant lesions (n = 176). The main risk factor for both was male gender. From the described suspicious malignant lesions, 31.8% were confirmed (n = 56), among which there were 43 basal cell carcinomas (BCC), 9 cutaneous melanomas (CM), and 4 squamous cell carcinomas (SCC). CONCLUSIONS: Data analysis pointed to a need for improved participant recruitment, especially of male participants, and health literacy assessment in future screenings.

Background: Acute kidney injury (AKI) after cytoreductive surgery followed by the infusion of hyperthermic intraperitoneal chemotherapy (CRS/HIPEC) is associated with a higher rate of major complications, resulting in prolonged hospitalization and increased mortality. Our objective was to evaluate the incidence of AKI and further progression to chronic kidney disease (CKD) in patients submitted to this procedure and recognize the associated risk factors. Methods: This retrospective study collected demographic, tumor-related, intraoperative, and postoperative data from 182 patients who underwent CRS/HIPEC from January 2016 to December 2019. Renal impairment was defined according to Kidney Disease Improving Global Outcomes criteria for AKI. We conducted univariate and multiple logistic regression analyses to assess the association between variables of interest and AKI. Results: Twenty-three patients (12.6%) developed AKI. In the AKI group, the risk for developing CKD was six times higher (odds ratio (OR) 6.48, confidence interval (CI) 1.601 - 26.255). Multivariate regression identified higher risk of developing AKI in patients who underwent HIPEC with cisplatin (OR 12.21, CI 1.26 - 109.70, P = 0.025), in each additional day spent in the intensive care unit (ICU) (OR 2.42, CI 1.07 - 5.45, P = 0.033), and an association for each unit increase in estimated glomerular filtration rate (eGFR) before HIPEC (OR 0.96, CI 0.94 - 0.98, P = 0.037) and AKI development. Conclusion: Patients who are at higher risk of AKI after CRS/HIPEC include those who performed cisplatin HIPEC regimen, had poorer preoperative renal function and had longer ICU stays. Early institution of preventive measures and frequent monitoring should be considered to minimize AKI risk and its associated morbidity, such as CKD progression.
RESUMO
Multiple myeloma (MM) frequently affects kidney function through multiple mechanisms. Nonetheless, some patients develop kidney injury due to other causes. A 54-year-old woman was diagnosed with IgG kappa MM developed IgA nephropathy without cast nephropathy. Further studies did not show criteria for MM progression or other causes. This case highlights the need for further investigation of kidney injury in MM patients (such as toxicity of previous drugs, infectious events, or immune-mediated disorders).
RESUMO
BACKGROUND: Acute kidney injury (AKI) often complicates the course of haematological malignancies (HMs) and confers a worse prognosis. The majority of these patients are managed by the attending physician, yet, a small group, mostly coincident with the worst presentation and outcomes, requires nephrology consultation, challenging the clinician with ethical issues regarding the decision to initiate or forgo renal support therapy. The purpose of this work is to identify the prognostic determinants for in-hospital mortality in this population. METHODS: A retrospective, observational chart review was undertaken at a single tertiary referral oncological centre. We reviewed the medical records of in-hospital patients with AKI and HM between 1 January 1995 and 31 December 2014 who met the criteria for RIFLE (Risk, Injury, and Failure; and Loss; and End-stage kidney disease) classification of I or higher and were followed by a nephrologist. RESULTS: Three hundred and forty-five patients were included in the study. Predictors of in-hospital death in patients with HM and AKI were septic shock [odds ratio (OR) 4.290 (95% CI 2.058-8.943)], invasive mechanical ventilation (IMV) [OR 4.305 (95% CI 2.075-8.928)] and allogeneic stem cell transplantation (SCT) [OR 2.232 (95% CI 1.260-3.953)]. The combination of each risk factor was used to estimate the probability of dying. Patients with all three risk factors had a risk of death of 86%. CONCLUSIONS: Septic shock, IMV and allogeneic SCT were identified as independent predictors of death in patients with HM and AKI, with only a small chance of survival if all three were present. Depending on the combination of risk factors, the indication for aggressive life support therapies, such as RST, might be questionable.
RESUMO
Graft-versus-host disease is one of the most frequent complications occurring after haematopoietic stem cell transplantation. Recently, renal involvement has been described as a manifestation of chronic graft-versus-host disease. Immunosuppression seems to play a major role: clinical disease is triggered by its tapering and resolution is achieved with the resumption of the immunosuppressive therapy. Prognosis is apparently favourable, but long term follow up data are lacking.We report a case of a 53-year-old man who developed nephrotic syndrome 142 days after allogeneic stem cell transplantation for acute myeloid leukaemia. Onset of nephrotic syndrome occurred after reduction of immunosuppressants and was accompanied by manifestations of chronic graft-versus-host disease. Histological examination of the kidney was consistent with Minimal Change Disease. After treatment with prednisolone and mycophenolate mofetil he had complete remission of proteinuria and improvement of graft-versus-host disease. Eighteen months after transplantation the patient keeps haematological remission and normal renal function, without proteinuria.Since patients with chronic graft-versus-host disease might be considered at risk for development of nephrotic syndrome, careful monitoring of renal parameters, namely proteinuria, is advisable.
