RESUMEN
BACKGROUND: The present survey aims to describe the intensive cardiac care unit organization and admission policies in Europe. METHODS: A total of 228 hospitals (61% academic) from 27 countries participated in this survey. In addition to the organizational aspects of the intensive cardiac care units, including classification of the intensive cardiac care unit levels, data on the admission diagnoses were gathered from consecutive patients who were admitted during a two-day period. Admission policies were evaluated by comparing illness severity with the intensive cardiac care unit level. Gross national income was used to differentiate high-income countries (n=13) from middle-income countries (n=14). RESULTS: A total of 98% of the hospitals had an intensive cardiac care unit: 70% had a level 1 intensive cardiac care unit, 76% had a level 2 intensive cardiac care unit, 51% had a level 3 intensive cardiac care unit, and 60% of the hospitals had more than one intensive cardiac care unit level. High-income countries tended to have more level 3 intensive cardiac care units than middle-income countries (55% versus 41%, p=0.07). A total of 5159 admissions were scored on illness severity: 63% were low severity, 24% were intermediate severity, and 12% were high severity. Patients with low illness severity were predominantly admitted to level 1 intensive cardiac care units, whereas patients with high illness severity were predominantly admitted to level 2 and 3 intensive cardiac care units. A policy mismatch was observed in 12% of the patients; some patients with high illness severity were admitted to level 1 intensive cardiac care units, which occurred more often in middle-income countries, whereas some patients with low illness severity were admitted to level 3 intensive cardiac care units, which occurred more frequently in high-income countries. CONCLUSION: More than one-third of the admitted patients were considered intermediate or high risk. Although patients with higher illness severity were mostly admitted to high-level intensive cardiac care units, an admission policy mismatch was observed in 12% of the patients; this mismatch was partly related to insufficient logistic intensive cardiac care unit capacity.

OBJECTIVES: Aim of the study was to investigate the effects of 1-year therapy by different proton pump inhibitors (PPIs) on epithelial tissue and surrounding inflammatory changes in Barrett's oesophagus, in patients who have abandoned invasive therapy. METHODS: A group of 120 patients (sampled in 60-month period, from 61201 upper gastrointestinal endoscopies) who were diagnosed both, endoscopically and pathohistologically with Barrett's oesophagus, and who have abandoned invasive therapeutic approach were enrolled in study. Treatment with different PPIs was initiated and continued for a year. At the end of treatment, patients were reassessed by endoscopy with tissue biopsy and pathohistological analysis. RESULTS: No difference in regenerating squamous epithelium or degree of dysplasia was seen between different treatment groups. Interestingly, most patients receiving pantoprazole (94%) ended up with thinner squamous epithel (P<0.0001). The squamous epithel was consider thinner only if its total thickness, measured on histological specimen, was smaller for more than 50% of the thickness before therapy. Significantly less of difference (P<0.0014) was seen with patients receiving lansoprazole (65%) and (P<0.003) omeprazole (50%). CONCLUSION: Regeneration of the squamous epithel was the same for all PPIs but not good enough to stop the progression of the disease.

The story of gastric acid secretion began with early ideas on gastric secretion (Spallanzani and de Réaumur, 17th century) and with first descriptions of food digestion (Dupuytren and Bichat, Beaumont, early 18th century), followed by proof that gastric juice contained acid (Prout, early 18th century). The research continued with first descriptions of gastric glands as the source of gastric acid and its changes upon digestive stimulus (Purkinje and Golgi, mid and late 19th century). The theory of 'nervism' - the neuro-reflex stimulation of gastric secretion by vagal nerve (Pavlov, early 20th century) was contrasted by a histamine-mediated concept of gastric secretion (Popielski and Code, mid 20th century). Thus, gastric acid and pepsin (Schwann, early 19th century) were found to be essential for food digestion and studies also pointed to histamine, being the most potent final common chemostimulator of oxyntic cells. The discoveries in etiopathogenesis of mucosal injury were marked by the famous dictum: 'No acid, no ulcer' ('Ohne saueren Magensaft kein peptisches Geschwür', Schwarz, 1910) that later induced the term of 'mucosal defense' and the notion that the breaking of 'gastric mucosal barrier' represents the initial step in the process of mucosal injury (Davenport, Code and Scholer, mid 20th century). The prostaglandins were shown to influence all major components of gastric mucosal barrier, described with the term 'cytoprotection' (Vane, Robert and Jacobson, 1970s). Beginning in the latter half of 19th century, the studies on gastric bacteriology that followed enabled the discovery of association between Campylobacter (Helicobacter) pylori and peptic ulcers (Warren and Marshall, 1980s) that led to worldwide major interventions in treating peptic ulcer disease. The surgical approach to peptic ulcer had been outlined by resection procedures (Billroth, Pean, Moynihan, late 19 century) and vagotomy, with or without drainage procedures (Jaboulay, Latarjet, Dragstedt, mid 20th century). Antacids, protective agents, anticholinergics, and later gastrin antagonists and prostaglandins were used for decades in the treatment of peptic ulcer, with differing effects. The advent of the concept of H(2)-receptor antagonists (Black, 1970s) and the discovery of acid (proton) pumps in parietal cells (Ganser, Forte and Sachs, late 1970s) paved the way for potent (H(2) antagonists) and profound acid inhibition (proton pump inhibitors) that revolutionized the treatment of acid-related disorders, including peptic ulcer disease. Worldwide, peptic ulcer and its complications remain the cause of significant morbidity, especially in older age groups, representing a major burden for ambulatory and hospital healthcare resources.

AIM: This study assessed the level of physical activity in overweight and obese subjects, and overweight and obese patients with Type 2 diabetes mellitus (T2DM). It also compared their physical activity level with that of the general population and investigated benefits of physical activity on anthropometric and metabolic parameters and blood pressure in the studied groups of patients using Baecke's questionnaire and the Lipid Research Clinics Physical Activity (LRC PA) questionnaire. The two questionnaires were also compared in the evaluation of benefits. METHODS: Physical activity level and other parameters (body weight, body height, body mass index, waist-to-hip ratio, systolic and diastolic blood pressure, lipoprotein and creatinine concentrations in the blood, concentration of fasting glucose and HbA1c in the blood, albuminuria-to-creatinuria ratio) of 136 subjects and their relationships were investigated during their out-patient visits. RESULTS: No difference in physical activity level was found among the four groups of investigated patients. The comparison between the level of physical activity in the investigated patients and the general population obtained by Baecke's questionnaire revealed a lower sports index in all groups of investigated men and obese women with diabetes mellitus. Our results confirm the benefit of physical activity on a high number of investigated parameters in the studied patients. The Baecke's questionnaire was found to estimate the effects of physical activity on metabolic and anthropometric parameters, as well as blood pressure, better than the LRC PA questionnaire, especially the two-point scoring system. CONCLUSIONS: LRC PA and especially Baecke's questionnaires are valuable aids in the estimation of physical activity level and its benefits in overweight and obese patients and patients with T2DM.

The authors have conducted a prospective investigation on 15 patients with hemodynamically unstable pericardial effusion (main criteria: echocardiographic signs of various degrees of right ventricular diastolic collapse and clinical instability) hospitalized in the Intensive Cardiac Unit (1.97% of all patients) for one year and have compared the results with literature data. The causes of pericardial effusion were neoplasms, infections, rupture of heart of aorta and hypothyroidism. Investigation revealed the most frequent findings: symptoms (dyspnea, retrosternal pain, loading intolerance, nonproductive cough), clinical signs (soft heart sounds, changes in pulmonal findings, fever, jugular venous distention, tachycardia, arterial hypotension and hepatomegaly), laboratory changes (elevated erythrocyte sedimentation rate, leukocytosis), ECG changes (ST-T abnormality, microvoltage, tachycardia) and chest X-rays changes (enlarged cardiac silhouette, pleural effusion). Echocardiography found an average width of pericardial effusion of 2.5 cm (+/- 1.2), frequently thickened pericardium and changes in heart motions. The most used drugs in therapy were indomethacin, antibiotics, analgesics and corticosteroids. In three patients pericardiocentesis, and in two pericardiectomy were performed. Two patients died, 13 patients were discharged from the ICU with an improved health condition. Literature data on this condition are either lacking, or differ from the above findings.

BACKGROUND: Local ischemia and mechanical trauma to hollow abdominal organs are quoted as a cause of gastrointestinal (GI) bleeding during and after long distance running. There are no data on athletes from rugby and other contact sports where mechanical trauma of the abdomen is frequent. METHODS: Occult bleeding in the stool of Croatian national rugby team players has been investigated during and after qualification match with Italy for the World Cup 1999 on June 6th 1998 in Makarska, Croatia. One player with positive test was followed and examined in detail after the game. RESULTS: Among 11 Croatian players authors discovered one with a history of GI symptoms and one with conversion of negative to positive test for occult bleeding in stool after the match. The latter player had no GI symptoms or diseases, took no medications, played only 20 minutes in the match on forward position. Conversion has been found in the second stool sample after game (24 to 48 hours after game). The athlete was followed for 18 months. Persistent low values of hemoglobin, hematocrit and serum iron were revealed, as well as expressed hemorrhoids without signs of haemorrhage or inflammation. CONCLUSIONS: Lower incidence of GI bleeding among rugby players than among long distance runners minimize the importance of mechanical abdominal trauma in the etiology of GI bleeding during sports activity. Hemorrhoids are not quoted as a cause of GI bleeding after sport activity among athletes.

BACKGROUND: Studies of rugby injuries in countries where rugby is not popular are rare. The aim of the study was to analyze the epidemiology and other characteristics of injuries in the first Croatian-Slovenian rugby league (CSRL) and the influence of anthropometric characteristics, body composition and constitution on the epidemiology of injuries. METHODS: Eleven anthropometric measures for the assessment of anthropometric characteristics, body composition and constitution were obtained in a sample of 111 voluntarily participating rugby players from the CSRL in the middle of the season 1996/97. After the season a questionnaire about injuries sustained in the past season was retrospectively filled up by 106 players who finished the first part of the study. Injuries were classified according to Garraway and Macleod and the 9th revision of the International Classification of Diseases. RESULTS: The incidence of injuries was 1.24 per 1000 hours of rugby training and 28.22 per 1000 hours of playing in matches. Low club position in rugby division (statistically significant, p<0.05), age from 25 to 34 years, forwards position in a team, being tackled, and beginning of autumn or spring season were identified as risk factors for injuries. The most frequent sites of injury were legs. The most frequent injuries were dislocations, strains and sprains of ankle and foot. CONCLUSIONS: The incidence of injuries in matches was more than two times higher than in more developed Scottish rugby, statistically positively correlating with the team position in division. There are no statistically significant differences in anthropometric characteristics, body composition and constitution of injured and uninjured players.

BACKGROUND: There are no data in important literature about the anthropometric characteristics of rugby players in countries where rugby is not a popular sport. The goals of this study were to analyze morphological anthropometric characteristics, body composition and constitution of players in the first Croatian-Slovenian rugby league (CSRL) with regard to player's position in the team, team position in the division, and to compare results with the results of rugby players from the more popular rugby leagues. METHODS: The study was carried out in a sample of voluntarily included 111 male rugby players from six clubs members of the CSRL, in the season 1996/97. Eleven anthropometric measures required for the calculations of body mass index (BMI), body fat percentage (BF%), and somatotype components were obtained in the clubs according to the recommendations by Jackson and Pollock and Heath and Carter. RESULTS: Forwards in the CSRL are on the average 93.5 kg heavy, 182.4 cm tall, with BMI 28.3 kg/m2, BF% 20.8% and somatotype 6.7-5.9-1.4. Backs are on average 82.2 kg heavy, 178.3 cm tall, with BMI 26.1 kg/m2, BF% 16.9% and somatotype 5.3-5.3-1.5. Backs from upper half of the division are on the average heavier than those from lower half, BF% in forwards from upper half of the division is higher than in forwards from lower half. Both differences were found to be statistically significant (p<0.05). CONCLUSIONS: Compared with the rugby players from more developed rugby leagues, forwards from the CSRL are lighter, backs are heavier and both have higher body fat percentage. Backs and forwards are more endomorphic and forwards are less mesomorphic compared with the rugby players from more developed rugby leagues.

The objective of this research was to determine the variability of the sample of professional ballerinas in the space of characteristics of their body composition and some functional characteristics according to the requirements of their roles in ballet. The sample of examinees was comprised of 30 professional ballerinas, members of the Croatian National Theatre Ballet (15 soloists and 15 members of the corps de ballet). The data showed that the soloists were characterized by a significantly larger knee diameter, significantly lower thickness of skin folds on the trunk and the lower fat body mass percentage, as well as by greater grip strength. Aerobic capacity was only moderately more developed than in fit people who participated in physical exercising because of recreational reasons, and there were no differences between soloists and the members of the corps.

This review article shows the development and organization of the "Croatian Model" of organization of health care for diabetic patients from Professor Vuk Vrhovac to this day, and its inclusion in the St. Vincent Declaration-a group of recommendations agreed upon in 1989 with the aim to decrease the morbidity and mortality of diabetes and its complications. The Model is organized on primary, secondary and terciary levels of health care. After the administrative changes of 1993, specialized health care for diabetic patients is delivered through County and Regional Centres for Diabetes and the Diabetes Reference Centre (the Vuk Vrhovac Clinic for Diabetes, Endocrinology and Metabolic Diseases), a scientific and educational institution and a WHO Collaborating Centre. Mention is made of the Croatian Diabetes Registry and statistical data on the morbidity (the prevalence of diabetes in Croatia is 2.37%) and mortality of diabetes mellitus and its complications, of organization of health care for diabetic patients, their medical treatment and care in Croatia.

During the 3 years of the trial (June, 1988--December, 1990), 128 patients underwent urgent diagnostic endoscopy and hemostasis for acute peptic-ulcer bleeding. In the first group consisting of 57 patients, hemostasis was carried out by thermocoagulation (heat probe), in the second one (54 patients) by injection sclerotherapy and in the third group, hemorrhage was controlled by a combination of heater probe and sclerotherapy. The first and second groups did not differ significantly in age, sex, hemoglobin values, size, location of an ulcer, and kind of bleeding lesions classified according to Forrest. The efficacy of thermocoagulation and injection sclerotherapy in the treatment of acute peptic-ulcer bleeding was compared. In the group of patients treated with the heater probe, the initial hemostasis was achieved in 56 (98%) patients, while rebleeding occurred in 6 (10.7%) patients. In the sclerotherapy group, the initial hemostasis was accomplished in 51 (94.4%) patients, while 8 (15.6%) patients experienced rebleeding. There was no statistically significant difference in ultimate hemostasis between the patients treated with heater probe (94.7%) and the sclerotherapy patients (88.8%). The incipient results of the treatment of bleeding peptic ulcers obtained by a combination of sclerotherapy and heater probe were extremely good, but the final conclusion will be brought after the research on a larger group of patients. The only patient that died during the treatment belonged to the sclerotherapy group.

Spontaneous bacterial peritonitis is one of the most common complications of ascitic fluid in patients with liver cirrhosis. The aim of this study was to investigate the role of total protein, albumin, globulin and complement ascitic fluid concentrations in development of spontaneous bacterial peritonitis in patients with liver cirrhosis. In patients with liver cirrhosis and spontaneous bacterial peritonitis (n = 8) the ascitic fluid total protein, albumin and globulin concentrations were significantly lower than in patients with sterile ascites (n = 11) (p < 0.01). The ascitic fluid complement C3 and C4 concentrations were significantly lower in patients with spontaneous bacterial peritonitis than in patients with sterile ascites (9.1 +/- 3.1 mg/dL to 22.9 +/- 17.4 mg/dL, p < 0.01; 3.8 +/- 5.9 mg/dL to 8.2 +/- 5.9 mg/dL, p < 0.01, respectively). The ascites total protein, albumin, globulin and complement concentrations in cirrhotic patients with spontaneous bacterial peritonitis were significantly lower than in patients with sterile ascites demonstrating the importance of those factors in ascitic fluid defense against secondary bacterial infection.

This prospective study was carried out on 33 patients with clinically, serologically and ultrasonographically confirmed amoebic liver abscess. All patients were randomly treated with metronidazole and chlorochin or a combination of medicamentous therapy and percutaneous drainage. Ultrasonographic characteristics of amoebic liver abscesses were rotound or oval shape, usually hypoechogenic content with specific dorsal sonic enhancement, and in the majority of cases, location near liver capsule. Shorter duration of amoebic liver abscess resolution time in the group of patients treated with the combined therapy was observed particularly in the first four weeks of the treatment. The authors concluded that percutaneous drainage in combination with medicamentous therapy represents a successful therapeutic approach in the treatment of amoebic liver abscesses.

A method is presented which combines gastro-oesophageal reflux quantification and oesophageal transit measurement so as to differentiate true reflux from residual oesophageal activity. A group of 33 subjects with gastro-oesophagitis reflux symptoms and endoscopically confirmed reflux oesophagitis and a group of 21 asymptomatic subjects with normal oesophageal, gastric and duodenal endoscopic findings were examined. The subjects were given 37 MBq 99mTc-Sn-colloid in saline orally and then scintiscanned dynamically. The gastro-oesophageal quantification was done after transit measurement and after the oesophageal time activity (to detect residual oesophageal activity) reached its minimum. The difference in the reflux indices between the two groups was highly significant. In low-grade oesophagitis measured reflux was lower than in higher grades of disease. Only 4.7% false-positive results were observed with a specificity of 95%, indicating that this method may be superior to methods published earlier.
