Human immunodeficiency virus seroprevalence trends: five hospitals in south Georgia, 1993 through 1997.

BACKGROUND: Human immunodeficiency virus (HIV) seroprevalence surveys help determine the extent of HIV and the need for routine HIV counseling and testing. We sought to describe trends in five south Georgia hospitals and compare two protocols for conducting anonymous HIV surveys. METHODS: From 1993 to 1997, each hospital tested approximately 1,400 anonymous, leftover blood specimens per year. Two hospitals (C and E) tested all specimens, and three hospitals (A, B, and D) excluded blood known to be HIV-related. RESULTS: The mean HIV seroprevalence at hospitals C and E was between 2.0% and 2.3% each year. The mean HIV seroprevalence at hospitals A, B, and D increased from 0.5% to 1.0% during 1993 to 1995, then decreased to 0.3% in 1997. CONCLUSIONS: In hospitals C and E, the level of HIV disease was constant. In hospitals A, B, and D, the HIV seroprevalence decreased to 0.3%, suggesting that routine HIV counseling and testing is not currently needed in these hospitals. Hospitals should consider conducting periodic anonymous HIV seroprevalence surveys, sampling from all patients and distinguishing between specimens known to be HIV-related and those that are not.

Missed opportunities for congenital syphilis prevention in an urban southeastern hospital.

BACKGROUND: Despite recent declines in syphilis rates nationally, recent outbreaks suggest that prevention of congenital syphilis remains an ongoing public health problem. GOALS: To identify missed opportunities for congenital syphilis prevention during prenatal care. STUDY DESIGN: Retrospective medical record review of 157 live birth or stillbirth deliveries that involved cases of congenital syphilis from Grady Memorial Hospital (Atlanta, GA). RESULTS: The hospital congenital syphilis prevalence was 8.2 cases per 1,000 live births. Six percent of case patients were HIV positive. Opportunities for earlier maternal screening, treatment, or diagnosis were missed in 60% of case patients who received timely prenatal care. Congenital syphilis cases attributable to preventable missed opportunities were significantly more common among case patients with fewer prenatal visits (66% versus 28%, P = 0.01). CONCLUSION: Provider efforts to reduce congenital syphilis in high-risk populations receiving prenatal care should focus on (1) screening patients at the first opportunity, at both the first prenatal visit and during the third trimester (i.e., 28 weeks); (2) performing on-site testing and same-day treatment; (3) providing appropriate treatment to infected women with penicillin allergy; (4) referring sex partners for treatment to prevent reinfection; and (5) screening all pregnant women attending emergency clinics.

Sexually transmitted diseases during pregnancy: screening, diagnostic, and treatment practices among prenatal care providers in Georgia.

BACKGROUND: Sexually transmitted diseases (STD) during pregnancy are associated with adverse outcomes. We conducted a prenatal care provider survey to determine STD screening, diagnosis, and treatment practices. METHODS: Standard questionnaires were mailed to Georgia-licensed obstetrician/ gynecologists, family practitioners, and nurse-midwives (N = 3,082) in 1998. RESULTS: Of the 1,300 care providers who returned the survey, 565 (44%) provided prenatal care, 390 (57%) were male, and 396 (70%) were obstetrician/ gynecologists. Overall, 553 prenatal care providers (98%) reported screening all pregnant patients for syphilis, 551 (98%) for hepatitis B, 501 (89%) for trichomonas, 474 (84%) for human immunodeficiency virus (HIV), 401 (71%) for gonorrhea, 403 (71%) for chlamydia, 475 (84%) for group B streptococci, and 130 (23%) for bacterial vaginosis (BV) (high risk). Less than 10% used amplification tests for chlamydia or gonorrhea. Most providers used appropriate regimens to treat STD in pregnant women. A written office policy on testing for BV or HIV was associated with increased screening. CONCLUSIONS: Provider education is needed about diagnosis and treatment of STD during pregnancy.

Barriers to prevention of perinatal group B streptococcal disease.

During 1992 the American College of Obstetricians and Gynecologists (ACOG) and the American Academy of Pediatrics (AAP) issued statements on prevention of group B streptococcal (GBS) disease. To assess prevention practices and identify barriers to preventing GBS disease, we surveyed obstetricians, family practitioners and general practitioners in Georgia during 1993. A standard questionnaire was mailed to 1190 clinicians in August and to nonresponders again in September. Of 436 (38%) physicians who responded, 192 (44%) provided obstetric care. Among these 192 obstetric care providers, 121 (63%) screened patients for GBS carriage antenatally. The most frequently cited reasons for not screening were "no clear guidelines" and "not cost-effective" (52 and 39%, respectively). Clinicians who screened patients were significantly more likely to believe that screening was cost-effective (P = 0.05). Of obstetric care providers who screened, only 9% obtained specimens using culture sites recommended by ACOG or AAP. Although most clinicians were aware that antenatal antibiotic treatment of carriers does not prevent perinatal GBS disease, 64% of those who screened reported that they gave oral antibiotics when carriage was detected during pregnancy. Of clinicians who reported using obstetric risk factors to guide prophylaxis choices, < 15% reported using intrapartum antibiotics for the conditions identified in the ACOG and AAP statements as those that suggest the need for prophylaxis when screening is not performed. Many Georgia obstetric care providers do not use effective practices to prevent perinatal GBS disease. Education on appropriate culture methods, obstetric risk factors and the cost effectiveness of prevention strategies might lead to more effective preventive practices.

XXY male with X-linked dominant chondrodysplasia punctata (Happle syndrome)

Happle syndrome is an X-linked dominant disorder with presumed lethality in hemizygous males; familial occurrence is rare. We describe a family with Happle syndrome affecting individuals in 3 generations. A man in this family is the first known male patient with Happle syndrome. He is severely affected; this may be due to his 47,XXY karyotype.

The prevalence of cervical infection with human papillomaviruses and cervical dysplasia in Alaska Native women.

Alaska Native women historically have high rates of sexually transmitted diseases (STDs) and invasive cervical cancer. Their prevalence of cervical infections with human papillomavirus (HPV) in relation to cervical dysplasia was determined with a commercial dot hybridization test for seven HPV genotypes. Type-specific HPV DNA, similarly distributed between genotype groups 16/18 and 31/33/35, was detected in 234 cervical specimens (21%) from 1126 Alaska Native women seeking routine care and colposcopy or from population-based lists. The prevalence of HPV DNA declined with age and increased with sexual activity and cigarette smoking. It was unrelated to use of oral contraceptives or condoms or to STDs. Relative risks associating HPV with increasing severe grades of cervical dysplasia increased markedly with HPV infection, up to 7.1 for high-risk genotypes 16/18 and 14.4 for coinfection with 31/33/35. These genotypes were detected in 8% of women without dysplasia seeking routine care. Screening for strain-specific HPV DNA may identify women at highest risk for cervical neoplasia.

Sexually transmitted diseases. Overview of the situation.

A discussion of the recent changes in the transmission of sexually transmitted diseases is followed with one about the factors that have caused those changes. Brief descriptions of the most common bacterial and viral sexually transmitted diseases are included. Finally, prevention and control strategies are explained, including health promotion, clinical care, detection, treatment, counseling, and partner notification.

Turcot's syndrome. Evidence for autosomal dominant inheritance.

A case of Turcot's syndrome (colonic polyposis plus a malignant central nervous system tumor) occurring in a kindred with autosomal dominant colonic polyposis is presented. It is proposed that Turcot's syndrome patients can be classified into Type I where only siblings are affected and Type II where two or more generations have colonic polyposis. A third nonfamilial group cannot be classified into Type I or II based on available information. Evidence is presented suggesting Turcot's syndrome is best considered an additional phenotype of familial polyposis and is most likely inherited in an autosomal dominant manner.

Segregation of an insertional chromosome rearrangement in 3 generations.

The interstitial deletion of a segment of chromosome 13, 13q21 leads to 13q22, and its inversion and insertion into the long arm of chromosome 3 at breakpoint q12, was found to segregate in 3 generations of a family. Segregation of this 3 break rearrangement gave rise to individuals monosomic, trisomic, or balanced for the involved segment. Monosomy for 13q21 leads to 13q22 was associated with mental retardation, expressive aphasia, microcephaly, hand abnormalities, and short stature. Partially trisomic individuals had normal mentality, extremely high arched palate, and mild dysmorphic features. There was no evidence for retinoblastoma in the individuals examined. The balanced carriers were normal. Comparison of monosomic individuals with one previous report of a similar deletion reveals marked phenotypic similarities.
