Review Case Reports
Corticodependent and recurrent inflammatory pseudotumor. Analysis of cases in our province and review.
Inflammatory pseudo tumor (IP) is an infrequent process with benign evolution in most cases whose etiology and pathogenesis are unknown. It usually affects young men and children, in whom the macroscopic lesion can mimic a malignant process, which is ruled out after biopsy. ⋯ We present a case of an inflammatory pseudo tumor with special corticodependence that began as a long-term periodic fever and splenic focal lesion that required splenectomy for its diagnosis and that, after decreasing the corticosteroid regimen, presented recurrences at the cerebellar and systemic level requiring the association of various immunosuppressants and rituximab to achieve remission. As a result of this case, we have performed an analysis of all the pseudo tumors diagnosed in adults in the hospitals of the province of Malaga, and it has been compared with that described in the bibliography.

Meta Analysis
Effect of serum uric acid and gout on the incidence of colorectal cancer: A meta-analysis.
Pathogenesis of colorectal cancer (CRC) depends on multiple factors. Identifying risk factors for CRC may facilitate the early prevention of the disease. We aimed to assess whether existing evidence suggests that serum uric acid (SUA) levels and gout are associated with CRC incidence. ⋯ Both SUA level and gout were associated with an increased risk of CRC. Maintaining low SUA levels may be beneficial in reducing the incidence of CRC. Further studies evaluating the precise mechanisms underlying this association are needed to establish whether SUA/gout causes CRC.

Observational Study
Elevated strong ion gap: A predictor of the initiation of continuous renal replacement therapy in acute kidney injury.
There is no optimal timing for continuous renal replacement therapy (CRRT) in acute kidney injury (AKI). AKI is a reason for the increased unmeasured anions, which refers to the increased organic acids in the blood, and they can be detected by calculating strong ion gap (SIG). SIG level at the moment of the AKI diagnosis may be a predictor for the initiation of CRRT. ⋯ Increased SIG at the moment of the AKI diagnosis in patients with AKI may be a predictive marker to initiate CRRT.

Cardiovascular diseases (CVD) are the main causes of death in hemodialysis patients, representing a public health challenge. We investigated the effect of different antihypertensive treatments on circulating levels of renin-angiotensin system (RAS) components in end-stage renal disease (ESRD) patients on hemodialysis. ESRD patients were grouped following the prescribed antihypertensive drugs: ß-blocker, ß-blocker+ACEi and ß-blocker+AT1R blocker. ⋯ ACE activity was decreased only in the ß-blocker+ACEi group compared to the ß-blocker+AT1R, while ACE2 activity did not change according to the antihypertensive treatment. Both Ang II and Ang-(1-7) levels also did not change according to the antihypertensive treatment. We concluded that the treatment of ESRD patients on hemodialysis with different antihypertensive drugs do not alter the circulating levels of RAS components.
