Cervical intraepithelial dysplasia (CIN 3) and history of herpes genitalis (HSV2) in women living in Attica, Greece.

This article presents a study on women living in Attica, Greece (an area of 4.5 million inhabitants) who visited the outpatient clinics of two specialized hospitals for a follow-up for cervical intraepithelial neoplasia (CIN 3). A random sample of 170 women with CIN 3 and a control group of 195 women coming from the general population were interviewed. A semi-structured designed questionnaire was used as an instrument for data collection. The aim of the study was to search for a possible correlation between CIN 3 and a past history of herpes genitalis (HSV2) of the women and/or their partners. According to the results, CIN 3 is more frequent among women between 26 and 40 years of age. The majority of the patients (70.3%) reported a past history of HSV2, but only 10.9% of the subjects in the control group had the same medical history (p = 0.000). Sixteen percent of the patients and only 5.3% of the subjects in the control group reported infection of their sexual partners with HSV2. 75 patients (44.6%) stated that they did not know if their sexual partners had a past history of HSV2, while only 27 women (13.3%) in the control group reported the same (p = 0.000). Patients reported more sexual partners than women in the control group.

Detection of the P and T waves in an ECG.

A method for the detection of the P and T waves, as well as the identification of their onset and offset boundaries in an ECG, is described in this paper. This method is based on a recently proposed "length" transformation, which exhibits some very interesting characteristics and can be utilized for one-channel or multichannel waveforms. The utilization of this transformation for the detection of the P and T waves in ECGs is exemplified in this paper. Experimental results are also given with real ECGs taken from the standard CSE ECG library.
