Objective: To summarize the epidemiological, clinical and serological features of syphilis.
Method: The clinical data of 1125 patients with syphilis were retrospectively analyzed.
Results: Non-marital sexual intercourse is the main route of infection. The 129 cases of primary syphilis were featured by extragenital chancres and the 357 cases of secondary syphilis were featured by scaling macules on the palms and soles and condylomata lata. Early latent syphilis were detected in 178 cases, late latent syphilis in 174 cases, and latent syphilis of unknown duration in 285 cases. Concurrent infection with other sexually transmitted diseases were noted in 107 cases (9.51%). Most patients were treated with benzathine penicillin, and only 31 patients (2.75%) were allergic to this therapy. Except for the primary syphilis, the sensitivity of syphilis serological tests (including rapid plasma regain test, treponema pallidum particle agglutination, treponema pallidum hemagglutination assay, and fluorescent treponemal antibody-absorption) were higher than 97%.
Conclusions: The incidence of latent syphilis is high, while the incidence of late syphilis is low. Penicillin remains the treatment of choice for syphilis.

November 2024
Hospital Juárez de México, Mexico City 07760, Mexico.
Background: The current economic and social crisis in Latin America has caused migration to the USA, bringing with it Public Health challenges due to the importation of various infectious diseases. Migrants, particularly those with chronic conditions, such as HIV infection and other sexually transmitted infections (STI), are at greater risk due to pharmacological interruption and access to medical care, so the timely detection of diseases acquired during their migration, such as malaria, is crucial to avoid health complications.
Objective: To outline by a multidisciplinary approach (Infectology, Parasitology, Epidemiology, molecular Biology, Venereology, and Public Health) the diagnosis and management of a male case with malaria imported to Mexican territory, HIV chronic infection, and latent syphilis.

- Venereal syphilis, caused by the bacteria Treponema pallidum, can escalate to serious complications like tertiary syphilis, which affects the heart decades after the initial infection.
- A case study highlights a 46-year-old woman who developed life-threatening cardiac issues, including an ascending aortic aneurysm and severe aortic valve damage, due to untreated late-stage syphilis.
- She underwent surgery to repair her aorta and replace the damaged valve, receiving antibiotics and intensive care; her recovery was satisfactory with no complications reported three months later.

Syphilis, caused by the spirochete , is a sexually transmitted infection (STI) that has seen a resurgence worldwide, particularly among populations at a higher risk of co-infection with human immunodeficiency virus (HIV). The disease typically progresses through distinct stages: primary, secondary, latent, and tertiary, each with specific clinical manifestations. Secondary syphilis is characterized by systemic involvement and various mucocutaneous symptoms, including a maculopapular rash that frequently involves the palms and soles along with fever, lymphadenopathy, and mucous membrane lesions.

Purpose: To evaluate judicious antibiotic prescribing of benzathine penicillin G (BPG) after implementation of an electronic health record-based medication shortage alert during a critical drug shortage.
Methods: This was an institutional review board-approved retrospective cohort study of patients aged ≥3 months who received BPG between May 9, 2023, and February 28, 2024. The study included inpatient and outpatient visits after implementing a BPG medication shortage alert; patients with severe penicillin allergy, neurosyphilis, or congenital syphilis were excluded.
