Prevalence of hepatitis B and C in the maternity department of a Greek district hospital.

OBJECTIVE: To define the prevalence of infection with hepatitis B virus (HBV) and hepatitis C virus (HBC), and the modifications observed during the last 8 years, amongst parturients who gave birth in our department. DESIGN: This was a retrospective study. PATIENTS: The 5497 parturients who gave birth in our department between October 1994 and September 2002. RESULTS: On average, 3.87% (213) of the pregnant women tested positive for hepatitis B surface antigen; 2.90% amongst pregnant Greek women and 4.67% amongst pregnant immigrant women. Among all pregnant women, 0.80% (44) tested positive for antibodies against HCV; 0.16% amongst Greek women and 1.33% amongst immigrant women. CONCLUSIONS: HBV prevalence in pregnant women did not seem to be affected by the increase of immigrants in our obstetric population over the course of time. HCV prevalence in the pregnant women, however, did seem to follow the increase of immigrants in our obstetric population. Economic and security issues unfortunately deprive some neonates, born to mothers with HBV infection, from the use of hepatitis B immunoglobulin.

The effect of casting solvent quality on the structure of polymeric Langmuir-Blodgett films.

The effect of casting solvent quality (good vs. [symbol: see text] solvent) on the structure of Langmuir-Blodgett films of a flexible-chain polymer [poly(dimethylsiloxane)] was examined on the basis of differences in the shape of Langmuir-Blodgett isotherms for two solvents, two temperatures, four polymer molecular weights, and three compression rates. The magnitude of a new index that describes the shape characteristics of the isotherm beyond the point of monolayer formation is found to be capable of separating all 48 isotherms studied into two groups, exclusively on the basis of the quality of the casting solvent. Experimental observations are supplemented by qualitative polymer physics interpretations regarding the structure of the films upon casting and compression.

Anticardiolipin antibodies levels in healthy pregnant and non-pregnant woman.

To determine the prevalence of anticardiolipin antibodies in healthy non pregnant women and during normal pregnancy, 110 healthy women of mean age 25 years old and 53 healthy pregnant females of mean age 24.5 years old, who no one suffered from any autoimmune disease, were studied. In all women the anticardiolipin antibodies were measured in duplicate by the Enzyme Linked Immunosorbent Assay (ELISA). There was no difference in the percentage of the positive anticardiolipin antibodies between non pregnant and pregnant healthy women (9.1% and 5.6% respectively). Also, there was no difference in the antibodies levels during normal pregnancy, as well as, during an equal time of observation in non pregnant women. The positive anticardiolipin antibodies levels were low.

AIDMAN--advanced informatics distributed medical access network.

We describe AIDMAN, a pilot project in which health clinics in remote areas of Greece are connected with mainland hospitals, to provide routine clinical service for both chronic health care and accident and emergency. Clinical practice is supported through the use of the Virtual Consultation Workstation that is being developed and evaluated specifically for the project and which is based on readily available commercial products and international standards. The communication infrastructure remains a major obstacle to any telemedicine project, and for this reason, satellite communication is used in the AIDMAN project to overcome the current lack of digital links and bandwidth. The proposed system will provide real time video, high definition image, shared applications and data over a link running at 128 kbps. In this paper we discuss the design of the AIDMAN system, the Virtual Consultation Workstation and the communication channel.

Double-blind evaluation of miconazole tampons, compared with clotrimazole vaginal tablets, in vaginal candidiasis.

Fifty-one patients with vaginal candidiasis and positive cultures in Nickerson medium were treated either with two miconazole tampons daily for five days (26 patients, median age 28 years) or with one clotrimazole vaginal tablet daily for six days (25 patients, median age 36 years) in a randomized double-blind trial. Seven days after the end of the treatment, 24 (92%) patients in the miconazole group and 19 (76%) in the clotrimazole group had negative cultures. One month after the end of the treatment, the relapse rate was significantly (P less than 0.05) higher in the clotrimazole group. Symptoms subsided rapidly in both groups. No unwanted effects were reported.
