Actinomycosis is very rare, as well as the central nervous system (CNS) condition associated with it, presenting a mortality up to 28%. Its manifestations could be similar to infectious conditions from other etiologies, thus, having a better understanding of the entity increases clinical suspicion and also it can provide a timely treatment. The clinical case of an adult with edema in an upper extremity is presented as a manifestation of thrombophlebitis and an abscessed axillary lesion, in which actinomycetes infection was confirmed. He presented a haematogenous spread with CNS involvement, with fatal ending.

Objective The objective of the study was to measure the proportion of patients who consulted for headache and of those who had a final diagnosis of migraine. We also assessed the proportion and characteristics of patients with migraine and the impact of migraine on the daily activities and the professional and social lives of patients visiting private/public medical centers in Guatemala, Costa Rica, Panama, and the Dominican Republic. Background Underdiagnosis of migraine is high in Central America and Caribbean urban communities. However, there is limited knowledge on characteristics of headache disorders for the appropriate classification of migraine, which is a prerequisite for targeted treatment. Hence, there is a need to improve migraine awareness among patients and medical professionals in this region. Methods Central America and Caribbean countries epidemioLogy study of Migraine (CALM) was a non‐interventional, cross‐sectional, multinational study in adults aged 18–65 years with a history of or current headache. The primary outcome was the proportion of patients with migraine visiting medical centers due to headache disorders. Using a specially designed migraine survey questionnaire, patients self‐reported migraine characteristics, duration, and severity of attacks and impact on work and social life. Results Of the 313 enrolled patients, 308 (98.4%) completed the study. Approximately 75.3% (232/308) of patients with headache visiting medical centers had migraine, with episodic migraine being the most common (193 [83.2%]). Overall, 34/308 (11.0%) patients had a new diagnosis of migraine. Among patients with migraine, 66 (28.4%) had a history of migraine for ≥20 years and 59 (25.4%) experienced severe pain. Overall, 52.2% (121/232) of patients reported that migraine affected their professional life and 78.4% (182/232) reported an impact on social life. Conclusion The CALM study establishes that a high proportion of patients with migraine had a long duration and high severity of migraine attacks, leading to a direct impact on work/social life as well as on costs incurred by patients in these countries.

La formación académica de estudiantes de medicina implica interacción con pacientes y superficies del entorno hospitalario, los microorganismos presentes allí pueden ser adquiridos y transmitidos con los riesgos consecuentes para la comunidad hospitalaria. El presente es un estudio descriptivo cuantitativo donde se analizan muestras provenientes de estudiantes de medicina (n= 155) en rotaciones de 3 semanas, tomando hisopados de nariz, boca, manos y fonendoscopio, gram y cultivo en agar sangre, incubación 24 horas a 37°C y 5% de CO2. Se hizo la identificación mediante gram y pruebas de biotipificación convencionales y susceptibilidad antibiótica según técnica de kirby-bauer.Los hallazgos aquí presentados evidencian alta frecuencia de bacterias patógenas en las fuentes de aislamiento, siendo relevante la presencia del Staphylococcus aureus en un 41,7% y la resistencia a antibióticos tanto por gram positivos como por gram negativos; por tanto, es de considerar la implementación de estrategias que minimicen la circulación de estos microorganismos en el ambiente hospitalario. El objetivo de este estudio es establecer la frecuencia de los microorganismos aislados en estudiantes de una Facultad de Medicina.
