Long Term Follow-up of Patients With Group A Streptococcal Infection Originating From the Genital...
Streptococcal InfectionsGroup A streptococcus (GAS) causes a variety of human infections. It is also an uncommon but serious cause of postpartum infections. In contrast to group B streptococcus (GBS) infection, which causes illness and death in newborns disproportionately more often than it does in mothers, perinatal GAS infection primarily affects mothers . Invasive GAS infection is defined by the isolation of GAS from a normally sterile site (e.g., blood) or by the isolation of GAS from a nonsterile site in the presence of the streptococcal toxic shock syndrome or necrotizing fasciitis. A postpartum case of invasive GAS is defined as isolation of GAS during the postpartum period, in association with a clinical postpartum infection (e.g., endometritis) or from either a sterile site or a wound infection. Because of the burden and severity of invasive GAS infection, the Centers for Disease Control and Prevention (CDC) hosted a meeting in to formulate guidelines for responding to postpartum and postsurgical GAS infections. However, we could not find any recommendations for long-term follow-up of patients who had GAS infection subsequent to delivery or gynaecological procedures, or further recommendations regarding subsequent delivery or gynaecological invasive procedures. It is possible that women who had GAS as a cause of vaginal infection may have a tendency to be carriers of this organism, but this has never been proven. We believe it is of importance to determine if women who have had one infection may be long-term carriers which may pose a risk during future pregnancies. The objective of the present study is to evaluate the incidence of long term gynaecological carrier state of patients who had GAS invasive infection following delivery, and to provide guidelines for follow-up and treatment of such patients. The proposed study may answer the question whether this endogenous GAS origin represents chronic GAS carrier state, similar to the known GBS carrier state. As some of these patients had severe infections (sometimes life threatening) a protocol for long-term follow up and management is necessary in case an invasive procedure is done (IUD insertion, endometrial biopsy, curettage or delivery) in order to prevent recurrent infection. The information collected in the study will enable us to afford recommendations for follow up and prophylaxis in the future. .
Risk Assessment of Long-Haul Truck Drivers
GonorrheaChlamydia Infections7 moreInternational studies have repeatedly documented a substantial prevalence of sexual risk behaviors and high rates of human immunodeficiency virus (HIV) and other sexually transmitted infections (STI) ranging from 5%-56% amongst long-distance truck drivers ("truckers") living in diverse international settings including India, Bangladesh, South Africa, China, Laos and Thailand. The prevalence of sexual risk factors and STI/HIV in US drivers is unknown. This proposal will provide both qualitative and quantitative data on HIV risk behaviors by interviewing and testing truckers working for established long-distance trucking firms, the sector which accounts for most of the jobs in the trucking and warehousing industry in the United States. The data obtained from this study will be used to inform the development of an HIV prevention intervention for long-haul truck drivers.
Study to Evaluate the Incidence of Hospitalizations and Respiratory Tract Infections in Premature...
Respiratory Syncytial Virus InfectionsThe purpose of this study is to describe respiratory syncytial virus (RSV) hospitalization rates and to begin to address the utilization of outpatient resources for RSV medically-attended lower respiratory tract infections (MALRI) in 32-35 week gestational age (GA) premature infants who are less than 6 months of age and do not receive treatment.
Tipranavir Expanded Access Program (EAP) in PI-experienced Patients With HIV-1 Infection
HIV InfectionsThis study was designed to provide early access to and evaluate the safety of TPV/r in PI-experienced patients with HIV-1 infection.
Natural History of HPV Infection in Men: The HIM Study
Human PapillomavirusThe purpose of this study is to learn about the natural history of Human Papillomavirus (HPV) infection in men. The study will also find out what factors are linked to HPV in men including other sexually transmitted diseases (STDs). If participants test positive for syphilis, gonorrhea or chlamydia, we are required by law to report the results to the Florida Department of Health. Participants will be able to get free medical treatment from the Florida Department of Health for these STDs. Participants will be given a written report of the results of the STD testing.
Hepatitis B and HIV Co-Infection in Patients in Uganda
Hepatitis BHIV InfectionsThis study will determine the amount of liver scarring (fibrosis) or liver damage in people infected with 1) hepatitis B virus (HBV, a virus that can infect the liver); 2) HIV (the virus that causes AIDS); 3) both HBV and HIV; and 4) neither HBV nor HIV. Liver fibrosis and liver damage can have many causes, including alcohol, certain medicines, exposure to some contaminated foods and infections with viruses that affect the liver (such as HBV). About 25 million people in sub-Saharan Africa are infected with HIV and about 50 million with chronic HBV, yet very little information is available on how many people are infected with both viruses and the medical implications of co-infection. Participants in Uganda s Rakai Health Sciences Program (RHSP) or Infectious Diseases Institute (IDI) clinic who are 18 years of age or older may be eligible for this study. People enrolled in the study come to the clinic for at least one visit and may be asked to return yearly. During the visit, participants undergo the following procedures: Questionnaire and a short interview about their health and quality of life. Physical examination and blood draw. The blood is tested for HBV and other factors that may suggest liver disease. Blood drawn at previous clinic visits or from other studies may also be tested. Liver evaluation using a FibroScan, a medical device that uses elastic waves to measure liver stiffness in a process similar to ultrasound scanning. For this test, the subjects lies flat on the back with the arm extended out. The tip of the machine s probe is covered with gel and placed on the skin between the ribs at the level of the right lobe of the liver. The machine produces a little tap on the skin that sends a wave out and checks how fast the wave moves. The speed of the wave indicates the amount of scarring in the liver.
Sexually Transmitted Infections Among African American Women Who Have Sex With Women
Sexually Transmitted InfectionsHIV InfectionsThe purpose of this study is to determine the rates of sexually transmitted infections (STI) among a group of African American women who have sex with women (AA WSW). The first study hypothesis is that AA WSW are at risk for acquiring and transmitting STI, including the human immunodeficiency virus (HIV). The second study hypothesis is that AA WSW participate in multiple high-risk sexual activities that may facilitate transmission of STIs, including HIV.
Human Papillomavirus (HPV) Infection in Pregnancy
Papillomavirus InfectionsPregnancy ComplicationsThe purpose of this study is to determine if maternal infection with human papillomavirus (HPV) is associated with pregnancy complications including spontaneous preterm delivery (sPTD), severe preeclampsia (PE), and poor fetal growth.
Risk Factors for Cytomegalovirus Disease in Solid Organ Transplantation

Studies of HIV-1 Infection in Newly Infected Individuals in Southern Africa
HIV InfectionsHIV SeronegativityThe main goal of this study is to find out how the immune system responds to a specific type of HIV infection, known as C HIV-1, in order to develop a vaccine against this type of infection. The study involves Southern African populations. The HIV-1 virus changes rapidly and many different subtypes have been found. In South Africa, limited data have suggested Subtype C HIV-1 is the most common. This study strives to verify the most common subtype and also look at genetic differences and immune responses among newly infected individuals. Results will aid in the development of vaccines specific for certain geographical areas.
