OBJECTIVE Although testing for Chlamydia trachomatis is encouraged and increasingly practiced at sexually transmitted disease (STD) and family planning clinics, patterns of testing and follow-up in other settings are not well described. To begin to address these issues, we performed a chart review of patients with a positive laboratory test for C.(More)
BACKGROUND AND OBJECTIVES To assess the spontaneous clearance of untreated Chlamydia trachomatis infections and factors correlated with the process. STUDY DESIGN Spontaneous clearance was assessed through review of laboratory database, chart review, and laboratory testing using direct immunofluorescence (DFA) and polymerase chain reaction (PCR) tests on(More)
OBJECTIVE To determine the proportion of symptomatic patients attending public sexually transmitted disease (STD) clinics who fail to seek care within 7 days of the onset of STD symptoms and their self-reported reasons for delays in obtaining care. DESIGN Interviewers administered 23-item questionnaire to a cross section of STD clinic clients between(More)
Bacterial vaginosis (BV) is characterized by dramatic changes in the vaginal ecosystem. Women without evidence of vaginal infection may exhibit transient changes in their flora. We prospectively followed up women by using diaries and self-obtained vaginal smears to correlate behaviors with changes in flora. The majority of women (38/51, 78%) had(More)
OBJECTIVE To compare self-reported doxycycline compliance in men and women attending an STD clinic with indications for Chlamydia trachomatis treatment to compliance measured using microprocessor-containing medication vials to count each time and date medication vials were opened. A secondary objective was to correlate outcomes of therapy, as measured by(More)
BACKGROUND AND OBJECTIVES Epidemiologic studies of chlamydial infections may often miss factors associated with the acquisition of infection. GOAL To evaluate factors associated with risk for initial and recurrent Chlamydia trachomatis infections. STUDY DESIGN A retrospective study of patients attending a sexually transmitted disease clinic and, within(More)
PURPOSE To determine utility of polymerase chain reaction (PCR)-based urine screening for Chlamydia trachomatis in the care of adolescent females in an urban clinic. METHODS Females > or = 15 years of age attending an adolescent clinic were approached consecutively. Each enrollee was interviewed to determine the primary reason(s) for the clinic visit and(More)
Keywords: EOG EEG Artifact removal Wavelet neural network (WNN) ICA Wavelet thresholding a b s t r a c t In this paper, we developed a wavelet neural network (WNN) algorithm for electroencephalogram (EEG) artifact. The algorithm combines the universal approximation characteristics of neural networks and the time/frequency property of wavelet transform,(More)
