Mycobacterium smegmatis bacteremia in an immunocompetent host.

Non-tuberculous mycobacteria can cause catheter associated blood stream infections. The causative agents are generally rapid growers that belong to the Mycobacterium fortuitum and Mycobacterium mucogenicum groups. A 65 year hospitalized patient with temporary central venous catheter who developed Mycobacterium smegmatis bacteremia. Bacteremia cleared after removal of the catheter. Patient was treated initially with 4 weeks of intravenous amikacin, intravenous meropenem, oral doxycycline and oral ethambutol and then deescalated to oral doxycycline and oral ciprofloxacin for 8 weeks. He improved clinically and remained stable. A literature search identified total of 22 articles that reported 47 unique cases of Mycobacterium smegmatis infection. To our knowledge, this is the first case of Mycobacterium smegmatis central venous catheter associated bacteremia in an immunocompetent host.

Intravenous metronidazole, liquid tinidazole, and intra-vaginal boric acid to cure trichomonas in a patient with gastric bypass surgery.

This study presents a case report of a female patient with symptomatic refractory Trichomonas vaginalis infection who was not able to clear her infection with high-dose oral metronidazole, oral tinidazole, intra-vaginal zinc sulfate, intra-vaginal metronidazole, intra-vaginal tinidazole, and intra-vaginal boric acid. She was unable to tolerate intra-vaginal paromomycin. A combination of intravenous metronidazole, oral tinidazole liquid suspension, and intra-vaginal boric acid for 14 days subsequently achieved a complete symptomatic and laboratory cure.

Women's willingness to experiment with condoms and lubricants: A study of women residing in a high HIV seroprevalence area.

The objective of this study was to investigate women's willingness to experiment with new condoms and lubricants, in order to inform condom promotion in a city with high rates of poverty and HIV. One hundred and seventy-three women (85.9% Black) sexually transmitted infection clinic attendees in Jackson, Mississippi, United States completed a questionnaire assessing willingness to experiment with condoms and lubricants and sexual pleasure and lubrication in relation to last condom use. Most women were willing to: (1) experiment with new types of condoms and lubricants to increase their sexual pleasure, (2) touch/handle these products in the absence of a partner, and (3) suggest experimenting with new condoms and lubricants to a sex partner. Previous positive sexual experiences with lubricant during condom use predicted willingness. The role women may play in male condom use should not be underestimated. Clinicians may benefit women by encouraging them to try new types of condoms and lubricants to find products consistent with sexual pleasure.

Dalbavancin Use for the Treatment of Methicillin-resistant Staphylococcus aureus Pneumonia.

Dalbavancin is a lipoglycopeptide with a long half-life that allows infrequent dosing. It is indicated for the treatment of acute bacterial skin and skin structure infections caused by susceptible organisms, including Staphylococcus aureus and methicillin-resistant S. aureus (MRSA). Although this agent has been used off-label clinically, there are minimal data in infections outside the current indications. We report a case of a 28-year-old nonadherent male with HIV presenting with pneumonia due to MRSA that was treated with dalbavancin. The patient was admitted to the hospital with classic pneumonia symptoms, and sputum cultures and bronchoalveolar lavage grew MRSA. Other infections were ruled out. The patient was initially treated with vancomycin, but subtherapeutic concentrations prompted a change to dalbavancin upon discharge. The patient was readmitted 11 days later with the complaints of hemoptysis and shortness of breath, with unchanged imaging. However, no evidence of MRSA was found at this time. Utility of dalbavancin for other disease states has profound implications, particularly in patients with poor medication adherence.
