Mpox (Monkeypox) Infection During Pregnancy.

BACKGROUND: An mpox (formerly "monkeypox") outbreak began in 2022, leading to infection in special populations, including pregnant individuals. CASE: We present a case of an individual who presented with a labial ulcer and subsequent papular rash at 31 weeks of gestation. She was diagnosed with mpox infection and was treated with tecovirimat. She had an uncomplicated induction of labor at 39 2/7 weeks of gestation and delivered a healthy neonate. The neonate had a positive immunoglobulin G test result for orthopoxvirus but did not have skin lesions or positive molecular test results suggestive of infection. CONCLUSION: Transplacental transmission of mpox is possible, but, in this case, the neonate did not have clinical findings suggestive of active or antenatal mpox infection. Treatment with tecovirimat in gestational cases of mpox may be beneficial.

Effectiveness of oral antibiotics for definitive therapy of non-Staphylococcal Gram-positive bacterial bloodstream infections.

BACKGROUND: Data on the effectiveness of definitive oral (PO) antibiotics for BSIs in preparation for discharge from hospital are lacking, particularly for Gram-positive bacterial BSIs (GP-BSI). The objective of this study was to determine rates of treatment failure based on bioavailability of PO antimicrobial agents used for GP-BSI. METHODS: This was a single-center, retrospective cohort study of adult inpatients admitted to an academic medical center over a three-year period. Patients with a non-staphylococcal GP-BSI who received intravenous antibiotics and were then switched to PO antibiotics for at least a third of their treatment course were included. The cohort was stratified into high (⩾90%) and low (<90%) bioavailability groups. The primary endpoint was the proportion of patients experiencing clinical failure in each group. Secondary endpoints included clinical failure stratified by antibiotic group, bactericidal versus bacteriostatic PO agents, and organism. RESULTS: A total of 103 patients met criteria for inclusion, which failed to reach the a priori power calculation. Of the patients included, 26 received high bioavailability agents and 77 received low bioavailability agents. Infections originated largely from a pulmonary source (30%) and were caused primarily by streptococcal species (75%). Treatment failure rates were 19.2% in the high bioavailability group and 23.4% in the low bioavailability group (p = 0.66). Clinical failure stratified by subgroups also did not yield statistically significant differences. CONCLUSIONS: Clinical failure rates were similar among patients definitively treated with high or low bioavailability agents for GP-BSI, though the study was underpowered to detect such a difference.

Inguinal phlegmon and positive serology for syphilis after penile bite laceration: true, true and unrelated.

Among many causes of penile injury, sexual activity is infrequently reported. The present case involved delay in recognition, which led to development of a phlegmon near major vascular structures. Positive serologic evidence of syphilis was an incidental finding.

Relationship between oral bacteria and hemodialysis access infection.

OBJECTIVE: Controversy exists concerning the association between oral bacteria and infection of hemodialysis (HD) shunts. The purpose of this study was to determine the extent to which oral bacteria are associated with vascular access site infections in a group of HD patients. STUDY DESIGN: Microbial blood culture data for 87 HD patients were collected: 53 via chart review (retrospective), and 34 with newly suspected vascular access infections (prospective). The primary outcome was the nature (i.e., species) of the bacteria recovered from blood cultures of subjects with vascular access infection, specifically those bacteria considered to be oral flora. RESULTS: The predominant bacteria reported to cause HD vascular access infections were Staphylococcus (48.6%) and Enterococcus (17.6%) species. Most infections occurred in hemodialysis catheters (89%) compared with AV grafts (11%) and AV fistulas (0%). The subclavian venous access (41%) and the internal jugular venous access (38.9%) were more commonly infected than other sites. None of the bacteria identified by blood cultures were considered to be oral flora. CONCLUSION: The results suggest that oral bacteria rarely, if ever, cause vascular access infections in hemodialysis patients.

Impact of amoxicillin prophylaxis on the incidence, nature, and duration of bacteremia in children after intubation and dental procedures.

BACKGROUND: Controversy exists about the impact of prophylactic antibiotics on bacteremia after invasive dental procedures. The purpose of this double-blind, randomized, placebo-controlled study was to determine the impact of amoxicillin prophylaxis on the incidence, nature, and duration of bacteremia from nasotracheal intubation and dental procedures in children. METHODS AND RESULTS: Children were randomly assigned before surgery to the American Heart Association (AHA)-recommended dose of amoxicillin or to a placebo. Aerobic and anaerobic blood cultures were drawn at 8 specific time points after intubation, dental restorative and cleaning procedures, and before, during, and after dental extraction(s), to include blood drawings up to 45 minutes after the last extraction. Aerobic and anaerobic blood culture results were used to determine the incidence, nature, and duration of bacteremia from these procedures. For the 100 children enrolled (mean age, 3.5 years), the overall incidence of positive blood cultures, defined as at least 1 positive culture of the 8, was significantly higher in the placebo (84%) than the amoxicillin group (33%) (P<0.0001). Bacteremia occurrence rates after intubation and after dental restorations and cleaning were 18% and 20% in the placebo group and 4% and 6% in the amoxicillin group (P=0.05 and P=0.07, respectively). At 1.5 minutes after the initiation of dental extractions, bacteremia occurred in 76% of the placebo group versus 15% of the amoxicillin group (P<0.001). The majority of the 152 positive cultures and of the 29 different bacteria identified were Gram-positive cocci. Bacteremia persisted longer in the placebo group. CONCLUSIONS: Bacteremia from these procedures occurs more often, from a wider variety of bacterial species, and for a longer duration after dental extractions than previously reported in any age group. Amoxicillin has a significant impact on the incidence, nature, and duration of bacteremia after nasal intubation, dental restorative and cleaning procedures, and dental extractions.
