This study will examine the phototoxicity, a reaction to light that is like exaggerated sunburn, which occurs in people who take medications such as voriconazole, a medication used to fight fungus. Sunscreens might protect the skin from the reaction. Although phototoxicity from voriconazole is not completely understood, it may be related to how that medication is metabolized in the liver by enzymes called cytochrome P450 enzymes-and mainly by one known as 2C19. A way to evaluate phototoxicity is through microarrays, which measure how much each gene is expressed in cells from tissues such as skin. Patients ages 8 and older who are scheduled to begin taking or who currently take voriconazole may be eligible for this study. Also, patients ages 18 to 45 in good health who have skin tone known as Type 2, which usually burns and tans only slightly following sun exposure, may be eligible. All patients will visit the Dermatology Clinic. They will complete two questionnaires, on medical history and medications, as well as the skin response to sunlight, and donate about 3 teaspoons of blood. Patients who are scheduled to take voriconazole will visit the clinic four times, that is, two visits 2 consecutive days before beginning the medication and two visits on 2 consecutive days after taking it for at least 7 days. Each visit will take 1 to 2 hours. Patients about to take voriconazole will have a blood test and undergo a physical exam of the skin test site, on the buttocks. Researchers will take photographs of the specific site and do tests to measure skin reaction to ultraviolet (UV) light. UV light will be shined on 15 small areas of the skin, each 1 x 1 centimeters. After 24 hours, any redness that occurs on the skin will be checked. Afterward, patients will begin taking voriconazole according to directions by the researchers. At 10 or more days later, patients will visit the clinic. Sunscreen will be applied and 1 hour later after administration of voriconazole, a blood sample will be drawn to check the level of medication. Then UV light will be shined on 23 areas of skin 1 x 1 centimeters. More photographs will be taken of test sites to record changes in skin redness. On the next day, the skin response will be evaluated. Participants in the control group will be asked to avoid UV radiation by wearing hats and clothing, and using sunscreen. They will be given the doxycycline, an antibiotic, and undergo procedures with UV light shined on small areas of the skin, on the buttocks. Control participants will have 7 study days, with visits lasting from 1 to 3 hours and probably not exceeding 8 hours. They will have two shave biopsies on Study Day 2 and on Study Day 7 to determine how the skin has responded to UV light exposures. ...

The purpose of this study is to evaluate the effectiveness of a short training program for general practitioners in patient-centered communication to reduce antibiotic prescription for acute respiratory tract infections (ARTI).

The purpose of this study is to evaluate the pharmacokinetics of a single dose of daptomycin in patients aged 2-17 years old who have a suspected or proven gram-positive infection for which they are receiving standard antibiotic therapy. The tolerability of a single dose of daptomycin in these patients will also be assessed.

Implantable venous access port infections are mainly due to coagulase negative staphylococci and may be managed by antibiotic lock therapy with retention of the port. Most of the time a vancomycin lock is used. Experimental data show that vancomycin may be poorly effective in eradicating the staphylococcal biofilm in the port. Another disadvantage of Vancomycin-containing lock solution is the occurrence of resistant organisms and the risk of catheter occlusion. Ethanol-containing lock solution is highly effective in vitro and does not expose to the risk of emergence resistance.

This Registry will enroll adolescent and pediatric participants who received at least one Gilead Hepatitis C Virus (HCV) direct acting antiviral (DAA) while participating in a Gilead-sponsored chronic hepatitis C clinical trial. The primary objective of this Registry is to determine the long-term safety of anti-HCV regimens in the pediatric population. Secondary objectives of this Registry are to determine whether subsequent detection of HCV RNA in participants who relapse following sustained virologic response (SVR) represents the re-emergence of pre-existing virus, the development of resistance mutations, or whether it is due to re-infection, and to characterize resistance mutations and the persistence of resistance mutations in pediatric participants who did not achieve SVR. Once enrolled, participants will be followed for up to 5 years.

Acute viral respiratory infections are among the most common causes of hospitalization in the pediatric population. The usual presentation of viral respiratory tract infections (VRTI) includes fever, malaise, wheezing and or coughing, rhinorrhea and loss of appetite. Up to 50% of children will have at least one viral-induced wheezing illness by school age. Currently treatment of VRTI is essentially supportive and no specific and efficient treatments are known. Given the lack of effective medications, current treatment for severe viral lower respiratory tract infection (LRTI) in infants relies on supportive measures only. These measures include supplementation of oxygen, monitoring of apnea, nasal/gastric tube feeding or intravenous fluids, and, if required, respiratory support with nasal bi-level positive-airway pressure. VTRI therefore represent an important unmet need for improved treatment strategies. Acupuncture's effect on has also been studied. Acupuncture has been shown to be a safe and effective in various respiratory tract inflammations. A review published in 2011 have found that acupuncture is safe for pediatric patients. Acupuncture's effect on acute viral induced wheezing and cough in hospitalized children has yet to be studied. Since the current standard of care is supportive care only, using acupuncture as an additional treatment may provide benefit in reducing wheezing, respiratory distress, and shorten hospitalization.

Background: Urinary tract infections (UTIs), the most common infection in pregnancy,are associated with several maternal and fetal complications, including maternal septic shock, preterm labor, intrauterine growth restriction and intrauterine fetal death. Thus, the prevention of UTIs in pregnancy is a very important goal. Several studies have suggested that alterations in the vaginal flora were associated with recurrent UTIs, and probiotic administrations may have a role in preventing those infections. Nevertheless, this has never been tested in pregnant women.

The investigators aim to assess the effectiveness of a 7-day compared with a 10-day course of antibiotic treatment for febrile urinary tract infections (UTIs) in children. It is formulated a hypothesis that a 7-day course of antibiotic therapy is equally effective as a 10-day course of therapy and would entail a lower risk of adverse events and better compliance.
