Abstract

The paper describes the relationship between direct solar radiation in a city (Warsaw) and in its broadly-defined suburban area (Belsk). The analysis covers the days of 1969-2003 when observations were carried out at both sites. The degree of extinction of solar radiation was expressed by means of Linke’s turbidity factor. Its mean annual value on the selected days of the period under consideration was 3.00± 0.10 in Warsaw and 2.87±0.11 in Belsk. Average atmospheric turbidity for individual seasons of the year as well as for the whole year was higher in Warsaw than in Belsk. In all cases, except for the summer, these differences were statistically significant. The period considered was divided into two sub-periods (1969-1993 and 1994-2003), in which atmospheric turbidity in Warsaw and in Belsk was compared by individual seasons and whole years. At both analysed sites Linke’s atmospheric turbidity factor decreased in 1994-2003, compared to the values for the earlier sub-period (1969-1993). However, the average annual atmospheric turbidity in Warsaw in comparison to Belsk remained the same, i.e. greater turbidity occurred in the city in both sub-periods.

Abstract

The aim of the study was to determine whether patients treated with anticoagulants in the perioperative period are at higher risk of developing bleeding complications.

Material and methods. Medical records of patients operated for abdominal hernia were analysed. Data concerning demographic characteristic of a group, type of hernia, comorbidities, preoperative anticoagulation therapy and complications were collected. Association of applied anticoagulation therapy with the time of drainage, the amount of drained discharge and the length of hospitalisation was evaluated.

Results. Analysed group consisted of 186 patients. Thirty seven patients were treated with different schemes of anticoagulant therapy before the the surgery. Patients treated with triple anticoagulation therapy (acetylsalicylic acid, low-molecular weight heparin, vitamin K antagonists) had significantly longer time of drainage in comparison to patients treated according to other schemes (p<0.05). The amount of drained discharge and time of hospitalisation did not differ significantly. Neither comorbidities nor the administration of low-molecular weight heparin did not affect the analysed parameters.

Conclusions. Patients operated on abdominal hernia, who were treated with triple anticoagulation therapy in peri-operative period, require significantly longer drainage of the wound what can result in prolonged hospitalisation

Abstract

Introduction: Fetal echocardiography is a method of choice for diagnosing cardiovascular anomalies prenatally. However, in the majority of cases, the complexity of a defect creates a diagnostic challenge. Moreover, postnatal validation of sonographic findings rarely can be obtained. Nevertheless, the feedback is vital for improving diagnostic capabilities. Thus, the aim of this research was to compare results of prenatal echocardiography with postnatal angio-CT in patients with anomalies of great vessels. Material and methods: We retrospectively compared results of prenatal echocardiography and postnatal angio-CT in 10 patients with selected anomalies of the aortic arch. This was a qualitative analysis, thus discrepancies in recognized anomalies were compared between these two modalities. Results: In 8/10 patient diagnoses were fully consistent. Nevertheless, the tiny caliber of vessels created a diagnostic challenge (e.x. to differentiate the hypoplastic aortic arch from the aortic arch interruption). In the remaining case, the discrepancy was due to a problem with complete visualization of all branches of the aortic arch in prenatal ultrasound. Conclusions: Fetal echocardiography in tertiary center was a reliable method for assessment of great vessels anomalies. However, critically narrow vessels remain a diagnostic challenge and neonatal angio-CT seems to be the method of choice in cases of diagnostic doubts.
