Long-term outcomes and reverse remodelling in recently diagnosed unexplained left ventricular systolic dysfunction.

Aims: In patients with recently diagnosed non-ischaemic LV systolic dysfunction, left ventricular reverse remodelling (LVRR) and favourable prognosis has been documented in studies with short-term follow-up. The aim of our study was to assess the long-term clinical course and stability of LVRR in these patients.

Methods And Results: We prospectively studied 133 patients (37 women; 55 [interquartile range 46, 61] years) with recently diagnosed unexplained LV systolic dysfunction, with heart failure symptoms lasting <6 months and LV ejection fraction <40% persisting after at least 1 week of therapy.

Human Infections by : A Mini-Review and the First Report of a Burn Wound Infection after Accidental Myiasis in Central Europe.

are bacteria that cause rare infections, typically associated with the infestation of an open wound with fly larvae. Here, we present a unique case report of the first isolation from a burn wound with accidental myiasis in a 63-year-old homeless man and a literature review focused on human infections caused by these bacteria. So far, 23 cases of infection with have been reported; in 52% of these, larvae were found in the wound area.

A novel postgraduate endoscopic course using a large animal model of secondary Crohn's disease stricture.

Background: The increasing complexity of advanced endoscopic techniques places a high demand on the endoscopist's expertise. Thus, live porcine models have been more frequently used for training. We briefly describe a hands-on postgraduate endoscopic course regarding a novel method of treatment of anastomotic strictures in a porcine model.

Novel porcine model of Crohn's disease anastomotic stricture suitable for evaluation and training of advanced endoscopic techniques.

Background And Aims: Currently, treatment options in postsurgical recurrence of stricturing Crohn's disease (CD) are limited. However, development of new invasive endoscopic techniques in clinical practice has safety constraints. The aim of this study was to create a large animal model of anastomotic stricture with CD properties to enable development of new techniques and training.

[Rare manifestation of CMV infection - circular stenosis of the stomach].

This article reports a case of a female patient who presented with epigastric pain. Further investigations confirmed CMV infection as a cause of stenosing gastric ulcer. In this case treatment with a proton pump inhibitor and antivirotic treatment led to a full recovery.

Distal urethral plate adhesions: New anatomical perspective in hypospadias.

Introduction: We found midline epithelial adhesions in the glandar urethral plate in patients with hypospadias. After dissolution, a blind epithelized channel becomes visualized inside of the plate pointing to immature embryonic luminization. In addition it reveals that the epithelized surface of the distal urethral plate is larger than previously considered.

A novel experimental model of acute respiratory distress syndrome in pig.

Acute respiratory distress syndrome (ARDS) is severe medical condition occurring in critically ill patients and with mortality of 33-52 % is one of the leading causes of death in critically ill patients. To better understand pathophysiology of ARDS and to verify novel therapeutical approaches a reliable animal model is needed. Therefore we have developed modified lavage model of ARDS in the pig.

[Arrhythmogenic left ventricular cardiomyopathy].

Arrhythmogenic left ventricular cardiomyopathy (ALVC) is a rare condition characterised by progressive fibrofatty replacement of the myocardium of the left ventricle in combination with arrhythmias of left ventricular origin. ALVC has been linked to autosomal dominant mutations of genes encoding desmosomal proteins, similarly to the classic arrhythmogenic right ventricular cardiomyopathy with which it also shares pathological and prognostic features. It seems that isolated left or right ventricular abnormalities represent two extremes of the spectrum of clinical manifestations of a single disease: arrhythmogenic cardiomyopathy.

Current Diagnostic and Therapeutic Aspects of Eosinophilic Myocarditis.

Eosinophilic myocarditis (EM) represents a rare form of myocardial inflammation with very heterogeneous aetiology. In developed countries, the most prevalent causes of EM are hypersensitivity or allergic reactions, as well as hematological diseases leading to eosinophilia. The disease may have a variable clinical presentation, ranging from asymptomatic forms to life-threatening conditions.

Absence of Borrelia burgdorferi in the myocardium of subjects with normal left ventricular systolic function: a study using PCR and electron microscopy.

Background: Several studies have demonstrated the presence of the Borrelia burgdorferi (Bb) genome in the myocardium of patients with dilated cardiomyopathy (DCM). To further support a causal relationship between the presence of Bb in the heart muscle and the development of DCM, demonstration of the absence of Bb in the myocardium of subjects with normal left ventricular (LV) systolic function is needed.

Aim: To determine the prevalence of Bb by polymerase chain reaction (PCR) and electron microscopy (EM) in individuals with normal LV systolic function and no history suggestive of myocarditis.

A rare case of regressively changed lipomatous hypertrophy of the interatrial septum presenting with anemia and recurrent fever.

Lipomatous hypertrophy of the interatrial septum (LHIS) is characterized by excessive accumulation of adipose tissue within some segments of the interatrial septum. Only one published case so far describes fever as a presenting feature of LHIS. On the other hand, systemic symptoms including anemia and fever are well-known clinical presentations of cardiac myxomas.

A high frequency of viral agents yet absence of Borrelia burgdorferi is seen within the myocardium of subjects with normal left ventricular systolic function: an electron microscopy study.

A wide range of viral agents is associated with the development of acute myocarditis and its possible chronic sequela, dilated cardiomyopathy (DCM). There is also increasing evidence that Borrelia burgdorferi (Bb) is associated with DCM in endemic regions for Bb infection. This study sought to use electron microscopy to prospectively analyze the presence of viruses and Bb within the myocardium of 40 subjects with preserved left ventricular (LV) ejection fraction and 40 patients with new-onset unexplained DCM during the same time period.

Arrhythmogenic substrate at the interventricular septum as a target site for radiofrequency catheter ablation of recurrent ventricular tachycardia in left dominant arrhythmogenic cardiomyopathy.

Background: Left dominant arrhythmogenic cardiomyopathy (LDAC) is a rare condition characterised by progressive fibrofatty replacement of the myocardium of the left ventricle (LV) in combination with ventricular arrhythmias of LV origin.

Case Presentation: A thirty-five-year-old male was referred for evaluation of recurrent sustained monomorphic ventricular tachycardia (VT) of 200 bpm and right bundle branch block (RBBB) morphology. Cardiac magnetic resonance imaging showed late gadolinium enhancement distributed circumferentially in the epicardial layer of the LV free wall myocardium including the rightward portion of the interventricular septum (IVS).

Early pericardial valve deterioration as a result of adhesions with native mitral valve.

We report an unusual case of early pericardial tissue valve prosthesis deterioration that required replacement. Four years after mitral valve replacement, 1 of the 3 leaflets of the valve was thickened and retracted in a fixed open position, which resulted in severe mitral insufficiency. The cause of this was adhesion of the leaflet and the patient's own retained posterior mitral valve leaflet.

[Outcomes of complex therapy in female patients after breast-saving surgery for breast carcinoma at the 1st Surgical Department 1st Faculty of Medicine, Charles University and General University Hospital in Prague during a ten-year follow up period].

Introduction: Good longterm outcomes of complex therapy in operable breast cancer can be achieved mainly due to early diagnosis of the tumor, adequate radicality of surgery and adequate oncotherapy. The following outcome criteria are considered significant: long-term survival rate in complete remission, a number of locoregional recurrences and a number of reoperations or mastectomies required by results of final histological examination, patient satisfaction with a cosmetic result of their breast- saving surgery. Comparison of complex treatment results collected from patients who underwent breast-saving procedures performed for breast cancer at our department of surgery with data reported in literature.

[Gall bladder adenomyomatosis].

Adenomyomatosis of the gallbladder (AMG) is not very common, however inherited and degenerative disease of the gallbladder with premalignant to malignant potential through metaplasia, occurring especially in a segmental form at higher-age patients, although the fundal form occurs more often. It can be found in 2-8.7% of resected gallbladder after cholecystecomy.

A case of an epignathus with intracranial extension appearing as a persistently open mouth at 16 weeks and subsequently diagnosed at 20 weeks of gestation.

We report a rare case of oral mass (epignathus) with intracranial extension originally suspected antenatally at 16 weeks' gestation because of a persistent open mouth. Postmortem MRI and pathologic examination of the fetus confirmed an oral teratoma with bilateral ventricular dilatation, corpus callosum agenesis, and a neuroepithelial intracranial cyst. The relevant literature regarding this anomaly is reviewed.

Herpes simplex virus-induced cardiomyopathy successfully treated with acyclovir.

Inflammatory dilated cardiomyopathy (DCMi) represents an acquired form of dilated cardiomyopathy. Viral infection is the most common cause of DCMi. In contrast with other cardiotropic viruses, herpes simplex virus (HSV) is a very rare finding in endomyocardial biopsies of patients with dilated cardiomyopathy.

Is it always possible to determine a diagnosis? Prenatal ultrasonography, post mortem magnetic resonance, autopsy.

Pathological-anatomical autopsy is the gold standard for determining of foetal abnormalities, but in some cases its role is limited (pathology of central nervous system, in particular, in case of ventricular dilatation or developed autolysis). In pathology of central nervous system, where insufficiency of autopsy can occur, additional post mortem magnetic resonance imaging (MRI) is performed to determine type of malformation. In this case report, we would like to point out the fact that although all investigating methods including post mortem magnetic resonance and autopsy (incl.

Benefits of examination by post mortem performed magnetic resonance imaging of foetus: haemorrhage in germinal matrix.

Post mortem magnetic resonance imaging is demonstrated as a supplementary method to classic pathological-anatomical autopsy in determining anomalies of the foetus. Frequently it plays a key role; primarily where the possibilities of performing autopsy are somehow limited (autolysis, ventricular dilatation). Specification of the final diagnosis subsequently enables us to improve prenatal diagnostics, both by means of magnetic resonance imaging and primarily by correlation with the prenatal ultrasound scan; this feedback improves the later method.

Presence of Borrelia burgdorferi in endomyocardial biopsies in patients with new-onset unexplained dilated cardiomyopathy.

Dilated cardiomyopathy (DCM) represents the third most common cause of heart failure and the most frequent cause of heart transplantation. Infectious, mostly viral, and autoimmune mechanisms, together with genetic abnormalities, have been reported as three major causes of DCM. We hypothesized that Lyme disease (LD), caused by spirochete Borrelia burgdorferi (Bb), might be an important cause of new-onset unexplained DCM in patients living in a highly endemic area for LD such as the Czech Republic.
