Recent reports demonstrated that levosimendan improved post-resuscitation myocardial function in rat and pig models. ⋯ In this rabbit model of bupivacaine-induced cardiac arrest, resuscitation with combined iv lipid emulsion and levosimendan was more efficacious than lipid alone (Tab. 3, Ref. 24).

Comparative Study
Ultrasound monitoring of the treatment of clinically significant knee osteoarthritis.
The study presented an ultrasound (US) monitoring of treatment as a new imaging US method with the results of therapy of clinically significant knee osteoarthritis. ⋯ We demonstrated a new method - US monitoring of therapy, which can objectivize the efficiency of treatment of clinically significant knee osteoarthritis. We would recommend US monitoring of therapy for the routine use in orthopedic clinical praxis (Tab. 6, Graph 3, Fig. 3, Ref. 15).

Comparative Study
COX-2, p16 and Ki67 expression in DCIS, microinvasive and early invasive breast carcinoma with extensive intraductal component.
Recent studies have showed a significant association between the combination of COX-2, p16 and Ki67 overexpression and incidence of subsequent invasive carcinoma in a subgroup of treated ductal carcinoma in situ (DCIS) and the indicated prognostic value of COX-2, p16 and Ki67 in early breast cancer. Based on the continual model of carcinogenesis and the mentioned results, we hypothesize, that if COX-2, p16 and Ki67 expression is prognostic for DCIS future behaviour, the expression level of the markers correlates also with different stages of breast carcinomas such as DCIS, microinvasive cancer and early invasive cancer with an extensive intraductal compound. The aim of this study was to compare the expression of COX-2, p16 and Ki67 in different stages of breast carcinoma such as pure DCIS, microinvasive cancer (T1mic) and invasive ductal carcinoma with an extensive intraductal component (IDC with EIC). The expression was assessed only in in situ component of the three subgroups (DCIS, T1mic, EIC) in order to show a possible correlation of COX-2, p16 and Ki67 with different stages of carcinogenesis. ⋯ This is the first published study ever assessing the expression of COX-2, p16 and Ki67 markers in different breast tumors containing DCIS compound. Our results showed an increasing expression pattern of COX-2 and p16 with the rising severity of the diagnosis (expression was measured exclusively in in situ lesions within tumors containing different extant of invasiveness). The same relationship was showed for p16 marker alone. These data support different expression pattern of COX-2 and p16 markers in combination and p16 marker alone in "in situ lesions" according to the stage of carcinogenesis. This fact might be useful in the evaluation of further behaviour of early breast tumors (Tab. 3, Fig. 8, Ref. 29).

The study was aimed at establishing an effective molecular-genetic method for detecting polymorphisms in genes CYP2C9 and VKORC1, which affect the pharmacogenetics of warfarin, and at determining their prevalence in Slovak population. ⋯ Slovak population is in Hardy-Weinberg equilibrium and frequencies of SNPs were in accordance with other published results in European populations (Tab. 5. Fig. 3, Ref. 51).

Breast angiosarcoma may occur de novo, or as a complication of radiation therapy, or chronic lymphedema secondary to axillary lymph node dissection for mammary carcinoma. Both primary and secondary angiosarcomas may present with bruise like skin discoloration, which may delay the diagnosis. Imaging findings are nonspecific. ⋯ Follow up: no further complications were detected during regular check-ups. However, 12-years later, patient reported significant changes at breast region which was exposed to radiation during treatment of original tumour. In this article, we describe the clinical presentation, imaging and pathological findings of secondary angiosarcoma of the breast after radiotherapy (Fig. 2, Ref. 26).
