Some considerations about the procedure of informed consent in patients prepared for electroconvulsive treatment

Electroconvulsive therapy (ECT) as a medical procedure of higher risk as well as a therapy evoking certain controversies requires strict obedience to the conditions of acquiring the patient's informed consent to the offered method of treatment. To acquire the patient's consent it is necessary to inform him/her about the different aspects of electroconvulsive therapy. The paper stresses that in the case of ECT therapy, the spoken information given to the patient seems insufficient. It is necessary to work out a Polish questionnaire for acquiring the patient's consent to electroconvulsive therapy and to apply it in all psychiatric institutions that carry out ECT procedures.     

Clinical analysis of pregnancy complicated by hypertension in the material of the Department of Obstetrics and Perinatology of the Pomeranian Academy of Medicine

OBJECTIVES: The aim of this study was retrospective analysis of arterial hypertension during pregnancy in the Department of Obstetrics and Perinatology of Pomeranian Academy of Medicine in Szczecin, and severe PIH intensive obstetrical care optimization. DESIGN: The retrospective analysis of 81 pregnancies complicated by arterial hypertension in the years 1995-2000 was performed. MATERIAL AND METHODS: The retrospective analysis of 81 pregnancies was performed. Patients were divided into two groups. In the first pregnancy was ended by caesarean section (n = 43), in the second by vaginal delivery. The mean gestational age, the way of delivery, accompanying diseases, uric acid levels, short term variability, Dawes - Reedman's criteria, presence of decelerations in CTG, Doppler PI, S/D, RI parameters in umbilical artery and cerebral arteries, presence of AEDVF and REDVF in umbilical artery were analyzed. RESULTS: Caesarean section was performed in 53.1% of all cases, in 46.9% vaginal delivery took place. Absolute range of short-term variability was more often less than 6 ms in caesarean section group (41.9%). Uric acid level was also higher in caesarean section group (p = 0.000194) CONCLUSIONS: 1. The caesarean rate in pregnancies complicated by arterial hypertension is over 50% and during severe PIH is approximately 100%. 2. Caesarean section takes place before estimated delivery date and indications to it are in most cases connected with a main disease 3. Short-term variability is lower among patients from caesarean section group. 4. Uric acid level is a relevant parameter of a degree of arterial hypertension, and the level is higher in first group. 5. Doppler velocimetry of umbilical artery and middle cerebral artery are valid part of obstetrical care among patients with PIH.     

Primary cardiac paraganglioma

We report a case of a 29-year-old male, who during workup of hypertension was found to have a malignant primary paraganglioma of the heart. The tumor arose from the site of the aortopulmonary window and right ventricular outflow tract (RVOT) and was removed with the aid of cardiopulmonary bypass. Reconstruction of the RVOT and pulmonary valve was necessary because of involvement by the tumor. The surgical course was uncomplicated, with normalization of catecholamine secretion and blood pressure.     

Procalcitonin as a marker of perinatal infection in newborn--preliminary data

Intrauterine and intrapartum infections in newborn infants are still difficult to recognise. The newborn does not manifest the classic clinical signs of infection usually observed in children and adults and up to now there is no good laboratory marker. In the last few years, procalcitonin (PCT) has been found to increase during different inflammatory processes, especially bacterial ones. In this study we analysed the clinical value of PTC in parturient, umbilical cord and newborn blood for predicting perinatal infection. MATERIAL AND METHODS: Thirty parturients with symptoms of intrauterine infection were classified for this study. Blood samples were obtained from the mother, the umbilical cord and the newborn on the second day of life. Serum was stored at -70 degrees C and thawed at the time of analysis. Among the newborns there were 21 infants without and 9 with symptoms and signs of infection. PCT concentration was measured by immunoluminometric assay--LUMI test PCT (BRAHMS). RESULTS: Statistically significant results were found on the second day of life: 5.83 (4.70) ng/ml in ill, 1.41 (0.68) ng/ml in healthy (p < 0.0005). We observed a significant correlation between PCT concentration in mother and umbilical cord blood (y = 0.40x + 1.06; p < 0.05), as well as between umbilical cord blood and venous blood on the second day of life in newborns (y = 0.16x 1.21; p < 0.01). CONCLUSIONS: Measurement of PCT concentration in perinatal period in the mother and in umbilical cord blood of the newborn may be useful for early diagnosis and monitoring of infectious complications in neonates. We need more data on reference ranges of PCT concentration in pregnant women, parturients and umbilical cord blood.     

Determination of von Willebrand factor activity with collagen-binding assay and diagnosis of von Willebrand disease: effect of collagen source and coating conditions

The collagen-binding assay was recently recommended as the new method for determining von Willebrand factor activity.(1-3) The assay is based on measurement of the quantity of von Willebrand factor molecules bound to collagen, similar to the procedure for an enzyme-linked immunosorbent assay. Many authors have reported problems in efficiently coating microplates with collagen and have suggested special procedures requiring chemical modification of the microplate surface and collagen or a high concentration of this protein and long incubation times.(4,5) Other studies indicate that the reasons for this problem are the origin of the collagen used for coating and the conditions under which the coating procedure is carried out. Modification of coating conditions and the use of an alkaline buffer permits the use of relatively low concentration of collagen, 5 to 10 microg/mL, and allows the test to be completed in one day. This procedure is useful in the diagnosis of von Willebrand disease and allows researchers to distinguish between disease types I and II.
