RESUMO
OBJECTIVE: The aim of this study was to evaluate the incidence and type of adverse drug reactions (ADRs) and identify risk factors for ADRs in elderly patients within 30 days following discharge from an internal medicine clinic. METHODS: A prospective observational study was conducted at the Internal Medicine Clinic of University Hospital Dubrava, Zagreb, Croatia, between September 1(st) and November 30(th) 2012. Patients aged ≥ 65 years discharged from the clinic during the study period were eligible for inclusion in the study. The follow-up visit was scheduled ~ 30 days after discharge. During the visit, the patients were assessed for the occurrence of ADRs. Two independent physicians evaluated each possible ADR by using the Naranjo ADR probability scale. Multivariate logistic regression analysis was used to identify predisposing factors for ADRs. RESULTS: There were 209 patients included in this study. A total of 72 ADRs were detected in 63 (30.1%) patients. The most frequent ADRs were bleeding disorders associated with warfarin therapy, followed by hypoglycemia associated with antidiabetics. Five (6.9%) ADRs, which resulted in hospital admission, were classified as serious. Multivariate logistic regression analysis indicated number of prescribed drugs ≥4 and prescription of furosemide and warfarin to be associated with increased risk of ADRs. CONCLUSIONS: Our study showed that ADRs are an important cause of morbidity in elderly patients after hospital discharge. Judicious prescription of drugs and careful and frequent monitoring of drug therapy are necessary to reduce the risk of ADRs.

AIM: To determine if red cell distribution width (RDW) is associated with all-cause mortality in patients on chronic dialysis and to evaluate its prognostic value among validated prognostic biomarkers. METHODS: This is a single center, prospective longitudinal study. At the time of inclusion in January 2011, all patients were physically examined and a routine blood analysis was performed. A sera sample was preserved for determination of NT-pro-brain natriuretic peptide (NT-pro-BNP) and eosinophil cationic protein. Carotid intima media thickness (IMT) was also measured. Following one year, all-cause mortality was evaluated. RESULTS: Of 100 patients, 25 patients died during the follow-up period of one-year. Patients who died had significantly higher median [range] RDW levels (16.7% [14.3-19.5] vs 15.5% [13.2-19.7], P<0.001. They had significantly higher Eastern Cooperative Oncology Group (ECOG) performance status (4 [2-4] vs 2 [1-4], Plt;0.001), increased intima-media thickness (IMT) (0.71 [0.47-1.25] vs 0.63 [0.31-1.55], P=0.011), increased NT-pro-BNP levels (8300 [1108-35000] vs 4837 [413-35000], P=0.043), and increased C-reactive protein (CRP) levels (11.6 [1.3-154.2] vs 4.9 [0.4-92.9], Plt;0.001). For each 1% point increase in RDW level as a continuous variable, one-year all cause mortality risk was increased by 54% in univariate Cox proportional hazard analysis. In the final model, when RDW was entered as a categorical variable, mortality risk was significantly increased (hazard ratio, 5.15, 95% confidence interval, 2.33 to 11.36) and patients with RDW levels above 15.75% had significantly shorter survival time (Log rank Plt;0.001) than others. CONCLUSIONS: RDW could be an additive predictor for all-cause mortality in patients on chronic dialysis. Furthermore, RDW combined with sound clinical judgment improves identification of patients who are at increased risk compared to RDW alone.

In April 2009, a novel influenza A (H1N1) virus was initially detected, and only after two months World Health Organization declared pandemic, while virus became globally present. We report here a confirmed case of patient suffering from H1N1 influenza pneumonia in an early period after heart transplantation. Complications of influenza A and B include viral pneumonia, secondary bacterial pneumonia and possibly acute allograft rejection in the setting of weaning of immunosuppression. In our case H1N1 influenza pneumonia was treated according to the published guidelines and had a mild course of disease, but nevertheless emphasis should be put on the prevention of disease applying known general infection control procedures and vaccination while disease course cannot be predicted.

Metabolic syndrome (MeS) is defined by a cluster of abnormalities comprising obesity, hypertension, carbohydrate intolerance and dyslipidemia. MeS increases the risk of developing various diseases, including coronary heart disease, stroke, peripheral angiopathy and type 2 diabetes. In our study, the subjects were 561 persons, residents of 11 homes for the elderly in Zagreb, Croatia. There were 160 men (28.5%) and 401 women (71.5%), aged from 56 to 96 years (the average being 79 years). Physical examination was conducted, which included blood pressure measurement, and body height and weight. Blood samples were taken for biochemical analysis. Along with other biochemical parameters, the levels of glucose, triglycerides and cholesterol (LDL, HDL-C) were also measured. The results have shown the prevalence of MeS in the elderly instutionalised people to be in the range of 20.8%, according to WHO criteria. The most common MeS component was hypertension, and it was significantly more frequent in women than in men; also, the elevated triglyceride levels were more often found in women; the difference between men and women was also statistically significant. MeS is a serious and growing health problem not only in Croatia but worldwide as well. Further studies are needed to verify the prevalence of MeS in Croatia, as it is a major risk for CVD and many other severe diseases.

Acute coronary syndromes whose clinical spectrum consists of unstable angina pectoris, non-ST-elevation myocardial infarction and ST-elevation myocardial infarction carry the greatest risk of death and severe complications to patients with coronary artery disease. Patients with acute coronary syndromes may be submitted to conservative or invasive management, with differences in the timing of invasive management in patients selected for that strategy. Early diagnosis, good monitoring and appropriate global assessment of every patient improve the selection of patients for adequate modality of treatment that will prevent death, complications and other serious events.

Resistant hypertension is defined as hypertension that remains above 140/90 mmHg despite the provision of three or more antihypertensive drugs in a rational combination at full doses and including a diuretic. It is associated with adverse clinical outcome and therefore requires aggressive medical treatment. We present a case of 70-year-old woman who was treated for resistant hypertension with a diuretic, ACE-inhibitor, calcium channel blocker, and with centrally acting antihypertensive, moxonodine. Despite of aggressive medical treatment her blood pressure remained above 160/90 mmHg continuously. Large diagnostic workup excluded common causes of secondary hypertension, but revealed significant carotid stenosis present on left internal carotid artery. Carotid endarterectomy was performed in order to improve cerebrovascular prognosis, but unexpectedly resulted in optimal control of her blood pressure. Two months after operation patient was on only one antihypertensive drug, having blood pressure below 130/85 mmHg. We suggest that in selected patients resistant hypertension could be associated with carotid stenosis and carotid sinus baroreceptor dysfunction. For definite conclusions further studies are warranted.

In the pathogenesis of asthma, oxidative stress appears to play an important role and existence of an oxidant/antioxidant imbalance is evident. In this study the key markers of oxidative stress and lipid peroxidation in the pathogenesis of asthma in childhood in comparison to healthy subjects were investigated. Plasma marker of the lipid peroxidation: malondialdehyde (MDA), the erythrocytes antioxidative enzymes: glutathione peroxidase (GSH-Px), superoxide dismutase (SOD), glutathione reductase (GR) and cysteine-containing tripeptide glutathione (GSH) were evaluated by spectrophotometric methods using blood samples collected from 37 healthy children and 44 asthmatic patients. The GSH-Px activity was significantly lower in asthmatic children (3.99 +/- 1.0 IU/g Hb) than in healthy controls (4.61 +/- 1.3 IU/g Hb; p < 0.034). Significant difference in activity of the SOD, GR, and concentration of cysteine-containing tripeptide GSH was not confirmed (p > 0.05). Lower GSH-Px activity in children with controlled asthma showed deficient erythrocyte antioxidant defence and evidence of association between oxidative stress and asthma in childhood. Preserved activity of GR and SOD, together with concentration of GSH and MDA, still seems to be crucial in controlling antioxidant/oxidant balance of the disease.

Cardiovascular diseases are the leading cause of mortality in Croatia. In concordance with this epidemiologic situation, a new organization of emergency medicine and a network of invasive cardiac laboratories have been introduced throughout Croatia. Main goal of this structuring is to improve the care of patients with acute coronary syndrome (ACS). The aim of this paper is to open discussion on the optimal way of treatment in patients with ACS in our country today, in the era of interventional cardiology of the 21st century. The pathophysiology of ACS encompasses a complex atheroinflammatory and atherothrombotic process with dynamic and progressive mechanical obstruction of coronary arteries and subsequently oxygen supply-demand mismatch. Conversely, the best way to treat such patients is reperfusion therapy, a goal nowadays achieved by either antithrombotic medical therapy or percutaneous coronary intervention (PCI). The weight of evidence does support the use of primary PCI as a standard and supreme reperfusion therapy, especially in myocardial infarction with ST elevation. The logistic complexities such as triage, transportation, the development of capable interventional center working 24-hours, even in developed countries, may be a major problem to use such a practice in the whole community. In ACS with non ST elevation, problems are even broader and include the importance of using optimal revascularization procedure (even cardiac surgery), timing and concomitant medical therapy, with certain stratification of every individual. Finally, especially for our country, medical and economic resources should be used optimally in order to achieve an optimal system to treat patients with ACS.

The aim of the study was to analyze the evidence-based use of antibiotic therapy in the treatment of acute pancreatitis and to identify factors influencing the introduction of antibiotic therapy in the setting of transitional country clinical hospital. This retrospective study was conducted at Department of Internal Medicine at University Hospital Dubrava in Zagreb, Croatia. Data were collected from hospital records of patients treated for acute pancreatitis from January 1st, 2005 till December 31st, 2005. Data collected from patients' histories were compared with indications for antibiotic treatment and antibiotics with demonstrated therapeutic efficacy in acute pancreatitis which were obtained from published literature. Logistic regression was used to identify factors with a significant impact on deciding on the introduction of antibiotic therapy, and multivariate analysis was used to identify factors with a significant impact on the cost of treatment. Statistical significance was set at p < 0.05. Antibiotic therapy was used in 67.7% of patients with acute pancreatitis. Combination of amoxicillin plus clavulanic acid was most frequently administered, either as monotherapy or in combination with metronidazole and/or gentamicin (37.3%), followed by cefuroxime (32.8%) and cefoperazone (26.9%). The choice of antibiotic was appropriate in 35.8% of study patients; however in 29.9% of patients who were administered antibiotics had no indication for this therapy; and 46.9% of patients who had indications for receiving antibiotic therapy didn't receive it. In the groups of patients treated with antibiotics, the cost of treatment was significantly higher compared to groups of patients who were not treated with antibiotics (p = 0.0035; p = 0.0026). In addition to antibiotic therapy, the cost of treatment was significantly influenced by the length of hospital stay and treatment at intensive care unit. The use of antibiotics in the setting of transitional country university hospital in patients with acute pancreatitis is not evidence-based. Decision on the introduction of antibiotic therapy is not based on objective parameters of disease severity or evidence of therapeutic efficacy of particular antibiotics. The cost of treatment is significantly increased by the use of antibiotic therapy.

The goal of our research was to determine how electrical cardioversion influences troponine I and brain natriuretic peptide (NT-proBNP) levels in patients with persistent atrial fibrillation (AF), without heart failure. Reaserch was conducted on 20 patients with AF. Before and after cardioversion levels of troponine I, creatine-kinase (CK), lactate-dehydrogenase (LDH) and brain natriuretic peptide (NT-proBNP) were measured. Average total applied energy was 344,2 +/- 268,9 Joule. After cardioversion CK level was insignificantly higher (113,3:259,0). Levels of troponine I did not change significantly after cardioversion (0,185:0,202). By measuring levels of NT-proBNP significantly lower levels of NT-proBNP were found after cardioversion (1095:432). There was a strong correlation between the duration of arrhythmia and the NT-proBNP level. Electrical cardioversion with standard recommended energy does not cause significant myocardial lesion. CK level elevation is a consequence of skeletal muscle lesion. Possible elevation of troponine I should be interpreted by another etiology. Increased production of BNP is caused by increased pressure and volume overload of the atrium, in patients with AF, independent of global cardiac function, according to that we think that in patients with AF discriminatory values of BNP in heart failure diagnostics should be corrected to higher levels.

Drug-induced myocardial infarction is not a common phenomenon and the underlying mechanism has been related with the coronary artery spasm in the majority of cases. It is mainly related to illicit substances such as cocaine, ecstasy, LSD and amphetamine. According to the findings in the literature, it is most likely that myocardial ischemia due to amphetamine abuse is a result of combined mechanisms which include coronary artery vasospasm, and in lesser extent thrombus formation or direct myocardial toxicity. Diazepam is also usually found as a substance of abuse. Recent findings indicate that diazepam exerts an inhibitory activity on different isoforms of the enzyme cyclic nucleotide phosphodiesterase, which can be found in the heart muscle and also show that diazepam potentate the positive inotropic effect of both noradrenaline and adrenaline, which subsequently leads to increase in myocardial contractility. We propose that dual intoxication with amphetamine and benzodiazepine potentate their effects on cardiac tissue and coronary arteries which results in larger myocardial injury.

This is the first report of a myxoid leiomyosarcoma arising in a cirrhotic liver. The tumor was resected from a 64-year-old man. On gross examination, it was soft and hemorrhagic. The tumor was composed of deceptively benign-looking smooth muscle cells with clear cytoplasm suspended in a myxoid stroma with foci of hemorrhage. Immunohistochemistry and electron microscopy confirmed that this was a smooth muscle cell neoplasm. The abundance of glycogen and ultrastructural signs of smooth muscle differentiation were considered consistent with an immature smooth muscle cell phenotype consistent with the diagnosis of myxoid leiomyosarcoma. Since myxoid leiomyosarcomas are aggressive tumors, it is important to recognize them histologically and also bear in mind that these tumors can occur even in unusual extrauterine locations such as a cirrhotic liver.

AIM: To evaluate self-assessed level of clinical skills of graduating medical students at Zagreb University School of Medicine and compare them with clinical skill levels expected by their teachers and those defined by a criterion standard. METHOD: The study included all medical students (n=252) graduating from the Zagreb University School of Medicine in the 2004-2005 academic year and faculty members (n=129) involved in teaching clinical skills. The participants completed anonymous questionnaire listing 99 clinical skills divided into nine groups. Students were asked to assess their clinical skills on a 0-5 scale, and faculty members were asked to assess the minimum necessary level of clinical skills expected from graduating medical students, using the same 0-5 scale. We compared the assessment scores of faculty members with students' self-assessment scores. Participants were grouped according to their descriptive characteristics for further comparison. RESULTS: The response rate was 91% for students and 70% for faculty members. Students' self-assessment scores in all nine groups of clinical skills ranged from 2.2-/+0.8 to 3.8-/+0.5 and were lower than those defined by the criterion standard (3.0-4.0) and those expected by teachers (from 3.1-/+1.0 to 4.4-/+0.5) (P<0.001 for all). Students who had additional clinical skills training had higher scores in all groups of skills, ranging from 2.6-/+0.9 to 4.0-/+0.5 (P<0.001 for all). Male students had higher scores than female students in emergency (P<0.001), neurology (P=0.017), ear, nose, and throat (P=0.002), urology (P=0.003), and surgery skills (P=0.002). Teachers' expectations did not vary according to their sex, academic position, or specialty. CONCLUSION: Students' self-assessed level of clinical skills was lower than that expected by their teachers. Education during clinical rotations is not focused on acquiring clinical skills, and additional clinical skills' training has a positive influence on students' self-assessed level of clinical skills. There was no consensus among teachers on the required level of students' clinical skills.

AIM: To evaluate the usefulness of echocardiography in the diagnosis of complete rupture of papillary muscle. METHODS: Transthoracic (TTE) and transesophageal echocardiography (TEE) was performed with the ATL 3000 HDI Ultrasound Inc (Bothell, WA, USA) with a 2.5 MHz transducer and 5-7 MHz multiplane phased array transducer. We are reporting about two patients (a 45 and a 51-year old male) with complete ruptures of papillary muscle following acute myocardial infarction (AMI). RESULTS: Both patients were previously treated with fibrinolysis in their local hospitals, 400 and 300 km, respectively, away from our hospital. Massive mitral regurgitation developed in both followed by rapid deterioration of hemodynamic state and severe heart failure, because of which both were transferred by helicopter to the Coronary Care Unit of our clinic. The diagnosis of complete papillary muscle rupture was confirmed in both patients by TTE and TEE. Due to the significant deterioration in their hemodynamic state, vasoactive drugs and intra-aortic balloon pump support were applied. Both patients then underwent mitral valve replacement, accompanied by concomitant coronary artery bypass grafting in one case. CONCLUSION: Transesophageal echocardiography is a more accurate and rapid diagnostic method in patients with mechanical complications of AMI than TTE.

Prosthetic valve endocarditis (PVE) is the most feared complication after valve implantation. It usually results in substantial morbidity and mortality in the postoperative period. An adverse effect on the annulus can cause conduction disturbances in the atrioventricular (AV) node, resulting in a high-degree AV block. This study describes a case of PVE that predominantly presented with sustained monomorphic ventricular tachycardia, which indicated a severe clinical course of PVE caused by a significant displacement of the aortic valve prosthesis. In our opinion, a very pronounced flap valve motion of the dehisced valve probably caused, in the critical moment, coronary artery blood flow limitation by means of coronary microembolization, which produced temporary ischemia and provoked sustained ventricular tachycardia. Furthermore, disturbances of rhythm such as ventricular tachycardia in the setting of endocarditis indicate a high-risk condition and should mandate fast and thorough noninvasive diagnostic procedures to obtain correct diagnosis even in the case of mild, slowly progressing disease.

Endocarditis represents a rare but life-threatening condition after heart transplantation. Recent American Heart Association guidelines recognize cardiac transplant patients with valvulopathy as high risk for endocarditis, but acknowledge that there were not sufficient data to make a recommendation for prophylaxis. Also, genitourinary procedures were no longer considered a risk factor for endocarditis in the most recent guidelines. We present a patient who acquired aortic valve endocarditis of the intact valve, after multiple urethral instrumentation 2 years after heart transplantation, who was successfully treated by aortic valve replacement and prolonged antibiotic therapy.

Percutaneous coronary intervention with stent placement is widely used to achieve revascularization of the myocardium, especially in acute coronary syndrome. There is increasing number of reports published concerning stent thrombosis both in bare metal stents as in drug eluting stents. According to the newest ACC/AHA/SCAI 2007th guidelines, bare-metal stent or balloon angioplasty is recommended as an optimal solution if surgery is to be performed in 6-12 months time after stent placement. We present a case of a 56-year-old male with colon carcinoma who suffered from post-operational myocardial infarction due to bare metal stent thrombosis, while the drug eluting stent remained patent. Currently, in our opinion, high level evidence is lacking in the literature in support for recommendations published in current ACC, AHA and SCAI 2007th guidelines regarding the choice of stent, antiaggregation and anticoagulation therapy. This case, together with others previously published suggests a need for development of an applicable strategy for selection and treatment of patients with increased perioperative risk of in-stent thrombosis in order to ensure optimal medical treatment.
