Epidemiology of human giardiasis in Romania: A 14 years survey.

Giardia spp. is the most common intestinal protozoan (causing gastrointestinal illness) and the most frequent cause of parasitic gastroenteritis in humans and animals worldwide. The aim of this study was to highlight new data in a specific area regarding clinical presentation and epidemiological prevalence over a long period of time. Patients (a total number of 54,623 patients) admitted in a tertiary center for infectious diseases serving a county for a period of 14 years were tested for infection with Giardia. Positive cases were recorded through analyzing the clinical complaints, the month of incidence and the demographic area from which the patients came from. Longitudinal trends have been evaluated. The incidence of giardiasis among the tested patients was 4.47%. A decreasing trend was observed regarding the annual incidence. Patients between the ages of 15 and 44 presented most commonly giardiasis, especially those from urban areas and women. The most common symptoms are loss of appetite (71.24%) and abdominal pain (69.07%). The highest monthly incidence was quoted in July (10.65%), August (10.49%) and June (10.20%). This epidemiological study allows a better knowledge of the infection with Giardia spp. It gives the long-term changes in demographic characteristics of the infected patients in a specific area and the monthly incidence.

Consequences of analgesics use in early pregnancy: Results of tests on mice.

Self-medication during pregnancy continues to be an issue in developing countries due to poor medical education. The most commonly used drugs are analgesics, mainly acetaminophen (paracetamol, APAP) and, to a lesser extent, ketoprofen (KPF). The aim of the study was to establish whether there are consequences of accidental use of these two drugs during early embryogenesis. The experimental study was performed on 30 pregnant white mice, divided into three groups: a first group to which APAP was administered, a second group to which KPF was administered, and group 3 as a control group. At delivery, the baby mice were examined, and after their first parturition, they were taken into study and examined according to the established protocol. Macroscopic and microscopic examinations of the liver and kidney were performed; liver and renal changes were recorded. Regarding the fertility, the number of fetuses born to mothers that were administered APAP and KPF corresponded to the normal values recorded in this species. Microscopic changes that were found in the kidney were as follows: APAP group - necrosis of the urinary tube, vascular congestions and vascular disorders; KPF group - ectasia, especially in the medullary cavity. Microscopic hepatic changes showed in the APAP group - vascular congestions, vascular disorders and hemosiderin deposits in the Kupffer cells; in the KPF group were found - discrete vascular disorders consisting in sinusoidal capillary ectasia and vascular congestions, as well as the presence of lymphocyte conglomerates. The aforementioned lesions indicate hepatic and renal distress with variable degrees of severity, but they appear to be reversible (the longer the time from the maximum effect of the drug the lower its toxicity).

What antibiotics for what pathogens? The sensitivity spectrum of isolated strains in an intensive care unit.

Antibiotic sensitivity spectrum of isolated strains differs according to hospital departments, the hospitals themselves, and countries. Discrepancies also exist in terms of antibiotic use and dosage. The aim of the present study is to compare the antibacterial agents, the types of infections, the number and type of pathogens, and the sensitivity to antibiotics used in the Intensive Care Unit (ICU) of the Emergency Clinical County Hospital of Oradea, Romania. Over a one-year period, data were gathered from the pharmacy computer system and medical records of inpatients. WHO Anatomical Therapeutic Chemical (ATC)/defined daily doses (DDD) methodology was used to assess drug administration data, and antibiotic use was expressed as DDD/1000 PD (patient days). The antibiotic susceptibility of isolated strains was expressed through the cumulative antibiogram. The overall consumption of antimicrobial agents was 1247.47 DDD/1000 PD. The most common drugs used were cephalosporins and fluoroquinolones (52.97% of the total). Ceftriaxone was the most commonly used, followed by levofloxacin. Infections of the respiratory and urinary tract were the most frequently diagnosed infections. The most commonly isolated bacteria type was Acinetobacter baumannii (22.12% overall), isolated especially from the respiratory tract and resistant to all the ß-lactam antibiotics including carbapenems. Antimicrobials intake at the ICU is much higher compared to medical and surgical wards. After we tested the existence of a possible connection between antibiotic consumption and antibiotic resistance of bacteria, it was revealed that on our sample exists a poor positive association.
