Antioxidants have been commonly used in medicine for thousands of years. Clinically, pentoxifylline and Ginkgo biloba have beneficial renal effects. Our study evaluated the nephroprotective effect of Gingko biloba in combination with Pentoxifiln in an experimental model of vancomycin-induced nephrotoxicity. Male Winstar rats were used in 3 groups: CONTROL, VANCO and VANCO+GBI+PTX and each group included 6 rats. Insufficient studies in the literature on the prevention of acute kidney injury by the combination of Ginkgo biloba and pentoxifylline led to the necessity to perform the study. Acute kidney injury was demonstrated by measuring serum values of classical markers such as urea and creatinine but also by measuring the urinary N-acetyl-β-d-glucosaminidase index, a topical marker in modern medicine. The significant decrease of the biochemical parameters in group III (VANCO+GBI+PTX) compared to group II (VANCO) and values similar to group I (CONTROL), demonstrates, the nephroprotective effect of the use in combination of the two substances.

Connections between vitamin D and psoriasis have been a matter of interest for the past decades, with its active metabolite, 1,25(OH)₂ vitamin D, being valued for antiproliferative and immunomodulatory effects. However, none of vitamin D’s actions could be possible without the CYP27B1 enzyme that bio-activates this metabolite of interest. In order to see if there is any link between the enzyme expression and the disease’s particularities, we conducted a preliminary study that involved 11 skin biopsies of patients with mild (n = 4) or moderate to severe psoriasis (n = 7). The cell proliferation antigen Ki67 and the CD45RO+ marker were also assessed. Compared with healthy skin, in psoriasis, it is reported that the enzyme’s expression seems to be more ubiquitous, but a clear correlation between the disease’s severity and the CYP27B1 expression was, to our knowledge, lacking. We found that, in patients with very mild psoriasis, the enzyme expression was observed in the epidermal stratum basale in a similar manner as in healthy skin specimens. Contrary, for higher severity scores, a divergent result was observed, with the enzyme being either variably spread in the epidermal stratum spinosum or completely absent. Unlike malignant diseases, a significant connection between CYP27B1 and Ki67 (p = 0.313) or CYP27B1 and CD45RO+ (p = 0.657) does not seem to be relevant in psoriasis.

Tuberculosis Peritonitis is a serious condition, whose diagnosis is established late due to the nonspecific nature of the clinical features, which delays the performance of imaging investigations and, implicitly, the setting of the diagnosis through biopsy and histopathological examination. We report the case of a 49-year-old man who presented in our clinic with nonspecific symptoms and significant nitrogen retention, with ascites fluid detected during the clinical–paraclinical examination, ultimately confirming the diagnosis of bacillary peritonitis. Confirmation of tuberculous etiology through biopsy and/or bacteriological examination is sovereign for the diagnosis. The therapeutic protocol includes three anti-tuberculostatic drugs, for a period of at least 6 months, with or without the combination of corticosteroid therapy during the first months of treatment. The patient evolution under treatment was initially favorable, but due to peritoneal adhesions, it underwent complications later.
