Liposarcomas of the paratesticular tissue and seminal cord represent a rare type of tumors, often misdiagnosed preoperatively. Therapy should include radical surgical excision, usually radical inguinal orchiectomy. If the margin status is in doubt, adjuvant radiation should be performed. Local relapse is common and may occur after several years, so follow-up period has to be sufficiently long.

AbstractThe large epidemiological studies demonstrated that atrial fibrillation is correlated with high mortality and adverse events in patients with acute myocardial infarction. The aim of this study was to determinate predictors of atrial fibrillation develop during the hospital period in patients with acute myocardial infarction as well as short- and long-term mortality depending on the atrial fibrillation presentation. The 600 patients with an acute myocardial infarction were included in the study and follow-up 84 months. Atrial fibrillation develops during the hospital period was registered in 48 patients (8%). After adjustment by logistic regression model the strongest predictor of atrial fibrillation develop during the hospital period was older age, particularly more than 70 years (odds ratio 2.37, CI 1.23-4.58, p=0.010), followed by increased of Body Mass Index (odds ratio 1.17, CI 1.04-1.33, p=0.012), enlarged diameter of left atrium (LA) (odds ratio 1,18, CI 1,03-1,33, p=0,015) presentation of mitral regurgitation (odds ratio 3.56, CI 1.25-10.32, p=0.018) and B-type natriuretic peptide (odds ratio 2.12, CI 1.24-3.33, p=0.048).Patients with atrial fibrillation develop during the hospital period had a higher mortality during the hospital course (10.4% vs. 5.6%) p=0.179. as well as follow-up period of 84 months than patients without it (64.6% vs. 39.1%) p=0.569, than patients without it, but without statistically significance. Patients with AF develop during the hospital period had higher mortality during the hospital course as well as follow up period of 84 months than patients without it, but without statistically significance.

Triple negative breast cancer (TNBC) account for 12% to 17% of all breast cancers. It is a heterogeneous group of tumors associated with aggressive clinical course. Insulin-like growth factor II mRNA binding protein 3 (IMP3) belongs to a family of insulin-like growth factor type II (IGF2), which plays a key role in the transmission and stabilization of mRNA, cell growth, and migration during embryogenesis. Increased expression of IMP3 is associated with aggressive behavior of different tumor types, advanced clinical stage, distant metastasis, and shorter overall survival (OS). The study included 118 patients with breast carcinoma diagnosed as TNBC and immunohistochemical staining for estrogen receptors (ER), progesterone receptors (PR), epidermal growth factor receptor 2 (HER2/neu), Ki-67, and IMP3 was performed. Correlations between categorical variables were studied using the chi-square and the Mann–Whitney U test. For survival analysis, the Kaplan–Meier method, log-rank test and the Cox proportional hazard regression model were used. Positive expression of IMP3 protein was present in 35.6% of TNBC. The presence of basal morphology was observed in 46.6% of TNBC. Positive IMP3 expression was connected with larger size of tumor, higher clinical stage, and basal morphology (P = .039, P = .034, P < .001). Disease-free survival and OS were significantly shorter in IMP3 positive TNBC. According to results of our study IMP3 expression can be used as negative prognostic factor for triple negative breast carcinomas. Targeting IMP3 molecule could be an effective approach to the management of a triple negative breast cancer with new immunological therapies, which does not yet exist for this group of tumors.

The aim of this study was to examine the spatio‐temporal appearance of different neuronal cell subtypes by analyzing expression patterns of several neuronal markers (calretinin, neurofilament 200 (NF200), vanilloid receptor 1(VR1) and calcitonin gene‐related peptide (CGRP)) of the embryonic human spinal cord (SC). Developing human SCs from 11 human conceptuses beetwen 5–10 developmental weeks (DW) were examined by light and electron microscopy and immunofluorescence. Light and electron microscopy revealed different embryonic stages of recognizable structure of the SC. NF200, CGRP and VR1 positive cells were observed in SCs during 5th–6th DW. NF200 was predominantly expressed in the ventral part, indicating presence of motoneurons. As development advanced, NF200 was mainly expressed in the marginal zone. Expression of CGRP was intense during all of the investigated periods, predominantly during the 5th–6th DW pointing to neural sensory differentiation, as opposed to the last DW when reduced expression of CGRP in the marginal layer indicated the terminations of the sensory afferents. Expression of VR1 was highest in the intermediate zone, at the beginning and at the end of the investigated periods, pointing to VR1 spatial pattern in the visceral afferents in the grey matter, while the first signs of calretinin were found in the 9th–10th DW ventrally. Delineating the relationships between factors involved in processes of neuronal differentiation as well as spatial and temporal arrangement of SC interrelated neurons can provide a useful information about normal SC development as well as the insight in possible causes of anomalies and disorders during embryonic life.

Background/Aim. The onset of atrial fibrillation (AF) in the acute phase of myocardial infarction (MI) may be a predictor of poor prognosis. The aim of our study was to examine this relationship. Methods. Six hundred patients were enrolled in the study and divided into two groups. The first group included 48 patients with new-onset AF and the second group of 552 patients without this arrhythmia. Patients with previously registered AF were excluded from the study. We investigated the correlation between new-onset AF and intra-hospital mortality as well as mortality during the follow-up period of 48 months. We also analyzed predictors of this arrhythmia. Results. Newonset AF was registered in 48 (8%) patients. The independent predictors of this arrhythmia were older age, particularly more than 70 years [odds ratio 2.37; 95% confidence interval (CI) 1.23-4.58) and increased body mass index (odds ratio 1.17; 95% CI 1.04-1.33). Patients with new-onset AF had a higher mortality during the hospital course than patients without AF, but this difference was not statistically significant (10.4% vs 5.6%, p = 0.179). Patients with this arrhythmia had also a higher mortality after follow-up period of 48 months than patients without AF (33.3 % vs 17.8%, p = 0.009). Major adverse cardiac and cardiovascular events (MACCE) defined as death, recurrent MI, revascularization, and stroke were more after registered in patients with new-onset AF than in those with no this arrhythmia after follow-up period of 48 months (52.1% vs 33.9%, p = 0.011). However, multivariate Cox's regression analysis demonstrated that new-onset AF was not an independent predictor of mortality during the follow-up period of 48 months (HR 0.68; 95% CI 0.38-1.20; p = 0.182). Conclusion. New-onset AF in patients with MI was associated with a higher mortality as well as MACCE after the follow-up period of 48 months but was not an independent predictor of mortality during this period.

Abstract

Patients with syncope following intensive emotional stress should be evaluated for malignant arrhythmias in the context of LQTS.

Histologically, papilary fibroelastoma is benign tumor of the heart. As demonstrated in this case, a papillary fibroelastoma can be an incidental finding discovered during echocardiography in patients with the history of hypertension.
