Obstetrical hysterectomy

OBJECTIVE: Obstetrical hysterectomy still remains life saving operation. The aim of study was to determinate the frequency, indications and complications after the operation in the hospital in Zielona Góra, Poland. MATERIALS AND METHODS: A retrospective review based on hospital data of 36 patients undergoing obstetrical hysterectomy over the period of 11 years was undertaken. RESULTS: The incidence of obstetrical hysterectomy during 1990-2001 et the Department of Obstetrics and Gynaecology in the district hospital in Zielona Góra was 1: 593 deliveries. Post partum hysterectomy occurred in 0.021% of normal deliveries and 1.03% of cesarean sections. The most common indications were placenta increta and placenta accreta /61.1%/, followed by uterine atony /13.8%/ and rupture of the uterus /11.1%. The most frequent complications were shock and lesion of the urinary bladder/both 5.6%/. The maternal mortality was 2.8%. CONCLUSIONS: 1. The most common indications for the obstetrical hysterectomy are: placenta's pathologies; uterine atony and rupture of the uterus. 2. Obstetrical hysterectomy is connected with high risk of complications and maternal mortality.     

Infusing gerontology into grades 7-12 social studies curricula

PURPOSE: This paper describes a model process to increase the exposure of middle and high school students to information on aging so they better understand the implications of an aging population and the stereotypes of older adults. DESIGN AND METHODS: A college Gerontology Institute, a social studies teacher education faculty member, and middle/high school social studies teachers collaborated on a program to develop and implement lesson plans that incorporate information on aging into existing courses. Institute staff provided expertise on gerontology and student teachers assisted in writing lesson plan objectives. RESULTS: Teachers developed about a dozen lessons covering from one class to two weeks in subjects such as global history, participation in government, Western civilizations, economics, and government. This experience suggests a number of issues that should be addressed when developing a gerontology infusion initiative with school teachers. IMPLICATIONS: Information on aging can be successfully incorporated into existing school curricula within the constraints of mandated learning objectives.     

Unusual presentation of purulent pericarditis: diagnostic contribution of MRI

Purulent bacterial pericarditis is an uncommon form of infectious pericarditis, occurring usually in immunocompromised patients. It may rarely present as a nodular or tumefactive lesion, and in such cases is liable to be confused with primary and metastatic tumors. We describe the imaging features and diagnostic contribution of CT and MRI in a 68-year-old woman with mass-like purulent pericarditis.     

Characterization of honeybee venom by MALDI-TOF and nanoESI-QqTOF mass spectrometry

The aim of the study was to comprehensively characterize different honeybee venom samples applying two complementary mass spectrometry methods. 41 honeybee venom samples of different bee strains, country of origin (Poland, Georgia, and Estonia), year and season of the venom collection were analyzed using MALDI-TOF and nanoESI-QqTOF-MS.     

Interactions of antirheumatic drugs with the superoxide generation system of activated human polymorphonuclear leukocytes

The effects of antirheumatic drugs on superoxide anion (O2-.) production by human polymorphonuclear leukocytes (PMNL) activated in vitro with phorbol myristate acetate (PMA) or N-formyl-methionyl-leucyl-phenylalanine (fMLP) were investigated. Chloroquine (CLQ), auranofin (AF) and chlorotriethylphosphine gold (CTEP-G) at 10(-6) to 10(-4) M inhibited PMA and fMLP induced O2-. production in a dose dependent fashion. These drugs had no effect on O2-. production by the hypoxanthine/xanthine oxidase system, indicating that their inhibitory effects were directed at the O2-. generating mechanism and that they were not scavengers of the O2-. formed. AF and CTEP-G inhibited the specific binding of 3H fMPL to PMNL membrane receptors, whereas CLQ had no effect. Colchicine (COL) and gold sodium thiomalate (GSTM) on the other hand did not significantly affect PMA and fMLP induced O2-. production or the specific binding of the ligands to PMNL. The antirheumatic drugs had no effect on isolated neutrophil membrane protease, a chymotrypsin-like enzyme that has been implicated in the activation of NAD(P)H oxidase. However, several of the drugs inhibited the enzymatic activity of a subcellular preparation of PMNL NAD(P)H oxidase, the order of potency being GSTM greater than CLQ greater than penicillamine greater than COL greater than AF approximately equal to CTEP-G. The isolated NAD(P)H oxidase was also inhibited by the thiol compounds--thiomalic acid and dithiothreitol, suggesting that the mechanism of inhibition may involve sulfhydryl-disulfide interchange reactions.
