Bacterial colonisation of the respiratory tract is commonly described and usually thought to be of no clinical significance. The aim of this study was to examine the presence and significance of bacteria and viruses in the upper respiratory tract of healthcare workers (HCWs), and association with respiratory symptoms. ⋯ We isolated high rates of bacteria and viruses in the upper respiratory tract of hospital HCWs, which may reflect greater exposure to respiratory infections in the hospital. Although respiratory infections are mostly symptomatic, the association between bacterial colonization and symptomatic illness is not clear. In the healthcare setting, HCWs may acquire and transmit infection to patients and other HCWs around them. Larger studies are required to explore ongoing occupational risk of respiratory infection in hospitals HCWs.

Randomized Controlled Trial Multicenter Study
The association between Bacillus Calmette-Guérin vaccination (1331 SSI) skin reaction and subsequent scar development in infants.
The Bacillus Calmette-Guérin vaccine (BCG) against tuberculosis is administered intradermally, and vaccination is often followed by a scar at the injection site. Among BCG-vaccinated individuals, having a scar has been associated with lower mortality. We aimed to examine the impact of vaccination technique for scarring in a high income setting, by assessing the associations between the post injection reaction, the wheal size, and the probability of developing a scar, and scar size. ⋯ Scarring after BCG vaccination has been associated with lower infant mortality. In a high-income setting, we found that correct injection technique is highly important for the development of a BCG scar and that registration of the category of BCG skin reaction (as wheal, bulge, or no reaction) may be used to identify infants at risk of scar failure. Finally, the wheal size was positively associated with both the probability of getting a scar and scar size.

Even though reported cases of syphilis have been increasing, cases of tertiary syphilis remain extremely rare. The majority of our knowledge with regard to complications of syphilis such as aortitis was acquired before the advent of relatively modern technologies such as CT, MRI and PET. This case report presents a rare case of syphilitic aortitis associated with a renal infarct caused by a peripheral arterial embolism diagnosed by CT. ⋯ Technologies, such as CT, PET-CT and PET-MRI, that were not present during the pre-antibiotic era, can provide new insights into rare presentations of tertiary syphilis such as aortitis. These imaging modalities show promise for early radiological diagnosis of aortitis in syphilis and may be useful for determining the response to treatment in specific cases.

A two-dose preoperative vaccination schedule against HBV has been the widely accepted policy in Poland. However, its effectiveness has not yet been assessed. ⋯ The success rate in achieving adequate immune protection with two dose HBV vaccination schedule in preoperatively vaccinated patients is relatively low, especially among those vaccinated less than five weeks prior to surgery. In more than a third of cases the standard three-dose regimen could have been implemented, as participants had time to complete a third dose. Current recommendations regarding a preoperative policy with a 2-dose vaccination schedule in Poland should be revised; the best time to perform surgery after the implementation of the second dose of vaccine in the context of patient protection against HBV infection would be between 38 and 60 days.

Review Case Reports
Staphylococcus aureus Prostatic abscess: a clinical case report and a review of the literature.
Prostatic abscess is a rare complication of acute bacterial prostatitis and is most commonly caused by Enterobacteriaceae. We report on a case of prostatic abscess caused by Staphylococcus aureus and conduct a review of the literature. ⋯ S. aureus is an uncommon cause of prostatic abscess. Optimal management includes both antibiotic therapy and surgical drainage. Our use of clindamycin as step-down therapy was guided by its excellent prostatic penetration.
