Renal and hepatic dysfunction or injury might be involved by ether based anesthetic and intravenous anesthetic drug or surgical stress. The purpose of this study is to compare the effect of moderate duration low-flow sevoflurane versus total intravenous anesthesia on renal and hepatic functions. ⋯ These results show that the renal and hepatic effect of moderate duration low-flow sevoflurane and total intravenous anesthesia is similar.

Breast lymphoma is a rare condition, both as a primary and a metastatic manifestation. The primary form has an incidence ranging from 0.04% to 0.5% of all breast neoplasms, whereas the metastatic form has an incidence of 0.07%. We hereby report a clinical case of a patient who presented with cutaneous non-Hodgkin lymphoma (NHL) in the left scapulohumeral region treated with surgery followed by radiotherapy (40 Gy total). ⋯ The following year, i.e. four years after the initial diagnosis of NHL, two lymphoproliferative relapses occurred: in the left cutaneous scapulohumeral region at the original site of disease, and in the right breast. The aim of this paper is to highlight an uncommon oncologic disorder such as breast lymphoma, highlighting its clinical and radiological manifestations. Some studies reported a possible aetiological role of radiotherapy in the development of breast cancer following treatment of NHL, and in the development of breast cancer following treatment of Hodgkin lymphoma, which could potentially explain our findings.

Peritoneal dialysis is the most important home dialysis treatment for end stage renal diseases and needs personal involvement, and support from the family. Peritoneal dialysis presented a number of discouraging technical problems and led to the belief that PD was not an appropriate renal replacement therapy, for patients with end stage renal disease. Despite the improvement of the method its rate remain low (11%) worldwide. ⋯ Late referral and the health care system seems to be very important factors that influence the dialysis modality choice. After the initiation of peritoneal dialysis we can see other factors that influence the survival of the method. The rate of peritonitis and the peritoneum function seems to be important issues.

Adipogenesis and osteoblastogenesis: trans-differentiation in the pathophysiology of bone disorders.
Mesechymal stem cells as pluripotent cells are involved in the differentiation of adipocytes under regulation of genes and transcription factors. The plasticity observed between adipocytes and osteoblasts differentiation is the basis of transdifferentiation, observed in both experimental and clinical level. ⋯ Disorders of this interaction include ectopic ossification syndromes and other bone disorders like osteoporosis and multiple myeloma. Further research will reveal the instinct mechanisms of this imbalance in the pathophysiology of many metabolic disorders such as diabetes mellitus, atherogenesis e.t.c.

Chronic kidney disease (CKD) is a global health problem associated with considerable morbidity and mortality and despite advances in the treatment of end stage renal disease (ESRD) mechanisms to prevent and delay its progression are still being sought. The renin-angiotensin-aldosterone system (RAAS) plays a pivotal role in many of the pathophysiologic changes that lead to progression of renal disease. Traditionally RAAS was considered as an endocrine system and its principal role was to maintain blood pressure (BP). ⋯ Several studies support these agents reduce proteinuria and protect renal function, whereas the opposite is stated by others. According to guidelines, their use is recommended as first line agents in diabetic renal disease and non diabetic renal disease with albuminuria, whereas there is no data to support the same in non diabetic nonalbuminuric renal disease. Dual blockage of RAAS with the combination of ACEIs and ARBs could offer an alternative in strict RAAS blockade, but studies up to now can not prove its safety and the combination is not recommended until ongoing trials will provide new and unarguable results.
