Association of physical trauma with risk of herpes zoster among Medicare beneficiaries in the United States.

Risk factors for herpes zoster (HZ) are poorly defined. An age-matched, case-control study was conducted to assess the effect of physical trauma on HZ, using Medicare data. HZ cases were 3.

Chronic medical conditions as risk factors for herpes zoster.

Objective: To determine the degree to which chronic conditions might contribute to the unexplained burden of herpes zoster.

Methods: We conducted a case-control study using MarketScan data from January 1, 2007, through December 31, 2007, to investigate chronic conditions as risk factors for herpes zoster among persons 20 to 64 years old. Cases were enrollees with a herpes zoster diagnosis (International Classification of Diseases, Ninth Revision, Clinical Modification codes 053.

Treponemal specific tests for the serodiagnosis of syphilis. Syphilis and HIV Study Group.

Objectives: To determine the rate of concordance of the Microhemagglutination Assay for Antibodies to T. pallidum (MHA-TP) and the Fluorescent Treponemal Antibody-Absorption test (FTA-ABS) prior to therapy in patients with early stage syphilis and to assess the incidence of and associated risk factors for seroreversion of these treponemal specific tests during the first year after therapy for early syphilis.

Design: Multicenter, prospective, cohort treatment study of patients with early syphilis.

Delayed care of pelvic inflammatory disease as a risk factor for impaired fertility.

Objective: We evaluated the relationship between delayed care of symptomatic pelvic inflammatory disease and impaired fertility.

Study Design: We used data from a cohort of women with clinically recognized pelvic inflammatory disease. Case patients were women with either ectopic pregnancy or infertility (n = 76); controls were women with intrauterine pregnancies (n = 367).

Pelvic inflammatory disease and fertility. A cohort study of 1,844 women with laparoscopically verified disease and 657 control women with normal laparoscopic results.

From 1960 10 1984, 2,501 women underwent diagnostic laparoscopy (index laparoscopy) because of a clinical suspicion of acute pelvic inflammatory disease (PID). Of these women, 1,844 had abnormal laparoscopic findings (patients) and 657 had normal findings (control subjects). The reproductive events after index laparoscopy of 1,732 patients and 601 control subjects were followed.

Breast-feeding among women attending women, infants, and children clinics in Georgia, 1987.

Breast-feeding is an important determinant of the health and nutritional status of children, particularly in lower socioeconomic populations. A major goal of the Georgia Special Supplemental Food Program for Women, Infants, and Children (WIC) is to increase the practice of breast-feeding among the women it serves. Breast-feeding practices were determined among a random sample of 404 women from a cohort of 2010 who attended WIC prenatal clinics in Georgia in 1986 and were expected to deliver in February 1987.

Sex partner recruitment as risk factor for STD: clustering of risky modes.

Nine hundred and fourteen heterosexual persons who requested care at STD clinics in South Carolina responded to self-administered questions on STD history, socio-demographic characteristics, number of sexual partners, and sexual partner choice. These data and the current STD diagnosis were analysed using multivariate techniques. Sexual behaviors of men and women were different.

Recurrence of low birth weight in siblings.

The recurrence of low birth weight (LBW, less than 2500 g) in full siblings was studied in 3286 singleton infants born between 1966 and 1986 to 1677 male U.S. Army veterans who were part of a nationwide health study.

Recurrence risk of neonatal hyperbilirubinemia in siblings.

The recurrence of neonatal hyperbilirubinemia (NHB) in full siblings was studied in 3301 live infants born between 1966 and 1986 to 1669 male US Army veterans who were part of a nationwide health study. The study population included 580 sibships with one infant, 679 with two, and 410 with three or more. Hospital of birth medical records were abstracted on these children.
