Diabetes mellitus is a major health problem with significant impact on the quality of life, due to both its complications and comorbidities and due to the costs it generates. There is widespread agreement that the incidence of the disease has increased over the last years, both due to better population monitoring and improvements in diagnosing methods.
Thus, the number of cases of diabetes mellitus worldwide was 382 million in 2013 and the number is rising; there are 75 million cases of diabetes mellitus which go undiagnosed, as the majority of diabetic patients are discovered only when complications set in. (1)

Hypertension associates with sudden cardiac death, its relationship with ventricular arrhythmias being demonstrated by numerous studies (1). Multiple mechanisms were proposed in order to explain this association, involving both structural and electrophysiological myocardial changes. The electrical ventricular remodeling includes non-uniform prolongation of action potential and duration heterogeneity of refractory periods and conduction velocities of adjacent myocardial areas. All of these changes are referred to as increased dispersion of ventricular repolarization.
As cellular basis for this important mechanism of arrhythmogenesis, 3 myocardial cell types were described, with distinct electrophysiological properties: epicardial, endocardial and midmiocardial M cells (2). Differences between their repolarization periods have as an electrocardiographic correspondence changes in T wave features (2). Subsequently, several non-invasive electrocardiographic (ECG) parameters were proposed for quantification of the repolarization dispersion such as QT interval duration, QT dispersion (QTd), T wave microalternans, and more recently, T peak - T end interval (Tpe), T peak - T end/QT ratio (Tpe/QT) and T peak - T end interval dispersion (dTpe).

Chronic heart failure is a major public health problem, with increasing prevalence due to population aging and increased survival of cardiovascular patients. Chronic heart failure is a clinical syndrome characterized by a variety of effects on other organs and systems. Occasionally, patients with chronic heart failure may present with signs and symptoms of a noncardiac disorder, such as hepatic dysfunction. The main pathophysiologic mechanism involved in hepatic dysfunction of patients with heart failure is either passive congestion due to increased filling pressures or low cardiac output and the consequences of impaired perfusion. Passive hepatic congestion may lead to increase of liver enzymes and total bilirubin. Right ventricular dysfunction can be associated with severe hepatic congestion, which can be asymptomatic and revealed only by abnormal liver function tests. When hemodynamic abnormalities are prolonged, the hepatic function is further altered, with impaired coagulation tests and decreased albumin synthesis. Morphologically, the liver becomes fibrotic and ultimately cardiac cirrhosis appears. Decreased perfusion from low cardiac output may be associated with hepatocellular necrosis and increased serum aminotransferases. Acute cardiogenic liver injury appears in severe systemic hypotension due to exacerbation of heart failure; the level of aminotransferases increases, as well as lactic dehydrogenase and prothrombin time.
The aim of our study was to evaluate the frequency and the importance of liver function tests abnormalities in a group of patients with chronic heart failure, as well as the prognostic value of these liver tests.

The Use of the Composite Muco-perichondrial-cartilaginous Vascularised Septal Flap in the Reconstructive Surgery of the Skull Base Defects

The original vascularised nasoseptal mucoperichondrial flap was described and used, in the endoscopic reconstructive surgery of the skull base tumors, for the first time in 2006, by two surgeons, Hadad and Bassagasteguy . This kind of vascularised flap provides the surgeons the ability to close large skull base deffects after removing sinonasal tumors. The vascularisation is provided by the posterior septal branch of the spheno-palatine artery . The flap is well vascularised and the surgeon is able to harvest a large surface flap using almost all septal mucosa from one nostril. Sometimes, if the defect that had to be reconstructed was very large, some authors reported that they harvested the nasal mucosa from the nasal floor too. Some modifications were reported on patients where the flap was created by using bilateral nasal mucosa, but no advantage was gained by sub-maximal, bilateral septal flap harvesting as compared to a single, large, long, unilateral flap, taken to the vestibular skin anteriorly and to the inferior meatus laterally including the palatal floor [2,3]. Bilateral mucosal elevation leaves denuded septal cartilage and bone on both sides of the septum which prolongs the return of nasal mucosal function unless a formal posterior septectomy is also performed. The large surface area of the nasoseptal flap allows great versatility of movement . It is capable of reaching any single segment of the ventral skull base, including the sella turcica, planum sphenoidale, clivus or the cribriform plate [4,5]. At its largest dimension, the nasoseptal flap is able to cover an entire anterior craniofacial defect from the frontal sinus to the planum sphenoidale and from orbit to orbit. The good vascularisation of the flap and the origin of the vascular source provide the surgeon with the ability to rotate the flap almost all directions .

Cervical cancer represents a major health problem, ranking worldwide as the second most frequent malignancy in women (1,2). Although screening tests for cervical cancer are widely utilized, there is still a large number of patients who are diagnosed in an advanced stage of the disease (3). The main patterns of tumoral spread involve mainly parametria, upper vagina, uterus and pelvic lymph nodes (4,5). The incidence of positive lymph nodes increases proportionally with FIGO stage: pelvic lymph node metastases range between 12% in stage Ib up to 43% in stage IIb (4). Metastases to the aortic lymph nodes are secondary to the pelvic ones, the risk of positive para-aortic lymph nodes rising up to 30 %; on the other hand, skip metastases to aortic nodes represents a very rare condition (6-10). Extended para-aortic lymph node dissection provides an appropriate debulking surgery, allows an adequate histological evaluation and disease staging and offers important information in order to plan the extension of postoperative radiation field (7-15).
