    Abstract Background: Canine tonsillectomy is performed due to acute or chronic tonsillitis, neoplasia, trauma or occasionally brachycephalic obstructive airway syndrome. Several tonsillectomy techniques are used but information about surgical complications is scarce. This retrospective study of patient records at the University Animal Hospital aimed to investigate complications related to canine tonsillectomy performed by 20-min clamping combined with monopolar electrosurgery. Inclusion criteria were bilateral tonsillectomy performed with "20-min clamping technique combined with monopolar electrosurgery without suture or ligation". Exclusion criteria were unilateral tonsillectomy, tonsillar neoplasia, additional surgical procedures other than tonsillectomy, cases where sutures were used initially, and cases where unspecified or other methods of tonsillectomy were used. The search of the patient records of the University Animal Hospital included a 10-year period. Complications that required additional anaesthesia were defined as major complications. Minor complications were handled during surgery or after surgery without surgical intervention.
    Results: Of 39 dogs that fulfilled the inclusion criteria, 11 dogs had complications and out of those 1 dog had two complications. Altogether, of the 12 complications, 2 were classified as major complications and 10 as minor. The most frequent complication was bleeding from the surgical site, in total 11 incidences; 10 dogs had an incidence of bleeding and out of those, 1 dog bled twice, both during and after surgery. Of these 10 dogs that bled, seven incidences of bleeding occurred during surgery and four incidences occurred after surgery. The two dogs with major complications were re-anaesthetized due to bleeding after surgery. No lethal complications occurred and all dogs survived to discharge.
    Conclusions: Bleeding during and after surgery was a common complication in dogs after bilateral tonsillectomy using "20-min clamping technique combined with monopolar electrocautery". Revision intervention was often needed, sometimes urgently. Although no comparison was made with another technique, the studied technique should be used with caution.

    Abstract Sexually transmitted infections (STIs) are increasing among men who have sex with men (MSM). Screening can improve the detection and outcome of asymptomatic STIs in high-risk populations. Self-sampling may be a resource-optimized strategy; however, its diagnostic reliability compared to testing by healthcare professionals (HCPs) requires further investigation. In this prospective, multicenter cohort study in a high-income country, asymptomatic MSM with a sexual risk profile for STIs were included. Sequential swabs for STI nucleic acid-based diagnosis of

    Abstract Background: At the beginning of the COVID-19 pandemic, when mortality was high, social distance was the only option to prevent transmission of SARS-CoV-2 and prohibit uncontrolled spreading. As the impact of social distancing on sexual behavior was unclear, we aimed to assess the influence of sexual risk behavior on SARS-CoV-2 seroconversion in HIV pre-exposition prophylaxis (PrEP) users after declaration of the pandemic.
    Methods: Prospective study on SARS-CoV-2 IgG-antibody seroconversion rate over time in men having sex with men (MSM) using PrEP at a single tertiary university hospital in Munich, Germany, during quarterly (Q) routine HIV-PrEP visits over 1 year per participant (May 2020 - September 2021). Seroconversion was defined as at least one positive anti-nucleocapsid (anti-N) SARS-CoV-2 IgG antibody test as surrogate for past infection. In addition, sexually transmitted infections (STIs), personal estimated risk behavior and sexual contacts were assessed.
    Results: Seroconversion rate during the full observation period was 7.3% (9/124 subjects) by September 2021. Percentage of subjects with symptomatic STIs (
    Conclusions: Our cohort showed low proportion of PrEP-users with anti-N IgG by September 2021, comparable to the local incidence. Sexual behavior in this cohort did not change, despite local recommendations for social distancing.

    Abstract Background: Symptoms of primary HIV infection, including fever, rash, and headache, are nonspecific and are often described as flu-like. COVID-19 vaccination side effects, such as fever, which occur in up to 10% of people following COVID-19 vaccination, can make the diagnosis of acute HIV infection even more challenging.
    Case presentation: A 26-year-old man presented with fever and headache following COVID-19 vaccination. The symptoms were initially thought to be vaccine side effects. A diagnostic workup was conducted due to persisting fever and headache > 72 h following vaccination, and he was diagnosed with Fiebig stage II acute HIV infection, 3 weeks after having unprotected anal intercourse with another man.
    Conclusion: Thorough anamnesis is key to estimating the individual risk of primary HIV infection, in patients presenting with flu-like symptoms. Early diagnosis and initiation of antiretroviral therapy is associated with better prognosis and limits transmission of the disease.

    Abstract Background: Data on ocular syphilis (OS) and its clinical presentation are currently insufficient. This study aimed to investigate the characteristics of a cohort with a high OS incidence at a university hospital in Germany, focusing on the clinical presentation of OS.
    Methods: This single-center cohort study retrospectively analyzed data on 90 patients with 109 episodes of syphilis between 2008 and 2018. Cases of OS were identified and additionally reevaluated through a study-specific secondary assessment by an ophthalmologist specializing in uveitis.
    Results: Twenty-three patients (26%) were diagnosed with OS, 16 (70%) of whom were with binocular involvement. Uveitis, especially that of the posterior segment, showed a high prevalence. Lumbar puncture was performed in 20 OS patients (87%), of whom 17 (85% of those with lumbar puncture/74% in total) met the 2018 Centers for Disease Control and Prevention criteria for likely neurosyphilis. Five (22%) of 23 patients had HIV infection, of whom 2 did not receive antiretroviral therapy. The preferred syphilis treatment regimens were benzylpenicillin and ceftriaxone, which yielded favorable serological, clinical, and ophthalmological outcomes.
    Conclusions: A high incidence of OS was identified, and physicians should be aware of uveitis as a manifestation of syphilis. Most patients presented with uveitis and syphilis in an early or late latent stage and showed central nervous system involvement.
