Infection by Pneumocystis jirovecii in patients with severe respiratory infection caused by SARS-CoV-2 is a situation that we must take into account today. Corticotherapy along with other risk factors predisposes to it. It is a diagnostic challenge and, after treatment, the prognosis is favorable. We report the case of a male with severe pneumonia due to SARS-CoV-2 who received corticosteroid treatment, later developing pneumonia due to P. jiroveci.

Since the arrival of the COVID-19 pandemic, countless consequences have been described regarding HIV infection in Chile, both in its diagnosis and prevention, mainly manifested in the decrease in serological tests, the interruption of care, the delay in starting antiretroviral therapy, and the lack of access to preventive methods. Added to this is the deterioration in some conditions related to social aspects and mental health. All this implies, among other consequences, a probable worsening in the epidemiological situation of HIV infection in Chile. Some of the designated impacts are reviewed in this article, and some challenges are raised to confront this problem.

Background: Due to their anti-inflammatory properties, it has been suggested that the use of statins could influence the evolution of influenza virus infection.

Aim: To evaluate the effect of statin therapy on mortality from influenza.

Methods: A meta-analysis that included studies evaluating the use of statins in patients with influenza and reporting data on mortality, after searching the PubMed/MEDLINE, Embase, and Cochrane Controlled Trials databases, was performed. A random effects model was applied. The risk of bias was analyzed and a sensitivity analysis was performed.

Results: Eight studies (10 independent cohorts), which included a total of 2,390,730 patients, were identified and eligible for analysis. A total of 1,146,995 subjects analyzed received statins, while 1,243,735 subjects were part of the control group. Statin therapy was associated with lower mortality (OR: 0.66; 95% CI: 0.51-0.85). The sensitivity analysis showed that the results were robust.

Conclusion: Our data suggest that, in a population with influenza, the use of statins was associated with a significant reduction in mortality. These results must be confirmed in future clinical trials.

Background: In Chile, cervical cancer is the second leading cause of death from malignancy in women. The main causal agent of cervical cancer is the human papillomavirus (HPV). Compared with the general population, sex workers (SW) are at increased risk of acquiring HPV.

Aim: To analyze the prevalence and genotypes of cervical and vaginal HPV in female SW attending a Sexual Control Centre.

Methods: A cross-sectional study was carried out on 97 women (19-70 years old). Two samples were taken per patient, one from exocervix and the other from vaginal walls. HPV DNA. was identified by polymerase chain reaction (PCR) and genotyping using specific probes for 32 types of HPV.

Results: The overall frequency of HPV was 45%, 41.2% in cervical carrier and 36.1% in vaginal carrier, 32% were co-infected, 63% of HPV were high-risk genotypes. The most frequent high-risk HPV was HPV 66 (12%), HPV 58 (9.3%), followed by HPV 16, HPV 59 and HPV 82 with the same frequency (8% each one). Thirty two (43%) of females were infected with multiple genotypes.

Conclusion: HPV is frequent infection among SW. This is the first study in Chile on the prevalence and genotypes of HPV in sex workers.

In the second half of the 19th century, the beginning of the research on tropical medicine was favored with contributions from shipping companies, like Dutch East India Company, being perhaps the most important of these its collaboration in the creation of the China Imperial Maritime Customs Service (1854-1950), imposed by consuls from England, France and USA, on the weak Chinese government in order to establish regular taxes in all its ports, soon expanding its functions with reports on tides, typhoons and weather, ending up creating a medical service in 1863 to detect epidemics and establish quarantines. This medical service published a Journal, the Imperial Maritime Customs Medical Reports, where they wrote distinguished investigators, such as Patrick Manson, Father of Tropical Medicine. We comment in some reports of this journal, to get an idea about its real importance in the development of tropical medicine.

Parasitic infections cause a huge burden of disease and are a current public health problem. The category of emerging or re-emerging disease is influenced by phenomena that occur in today's interconnected world because of globalization, the displacement of people, trade, uncoordinated urbanization and climate change, they have a very important influence on transmission of these diseases. In 2021 there was an increase in the number of patients who have required treatment for diphyllobothriasis in the Los Ríos Region. This article reviews aspects related to integrated Health Service networks to provide access to pharmacological treatments to patients diagnosed with diphyllobothriasis (tapeworm infection), implemented by the Valdivia Health Service Department, in collaboration with the San José de Osorno hospital, primary care centers and private centers in the Los Ríos Region.

Toxoplasmosis is one of the most prevalent parasitosis in the world. It is associated with perinatal morbidity and in immunocompromised population. Currently, there are several diagnostic tests, both serological and molecular, that can help confirm the diagnosis and differentiate a recent infection of a pass. We propose some recommendations for the diagnosis and treatment of toxoplasmosis in different clinical scenarios based on the currently available evidence.

Cervicitis is a frequent condition caused mainly by sexually trans- mitted agents. The clinical spectrum varies from absence of symptoms to extensive inflammatory processes that may simulate a malignant neoplasm. We present a clinical case of an adolescent with genital ulcers and systemic disease. Speculoscopy revealed a tumoral-looking cervix. Laboratory studies confirm infection with herpes simplex virus 2 (HSV-2) and Mycoplasma genitalium, together with a histological study that ruled out neoplasia. It progresses favorably to antimicrobial treatment, with recovery of the appearance of the cervix. Cervicitis rarely presents with necrotic involvement. Co-infection with HSV-2 and M. genitalium infection may have been the determinant of cervical damage and the necrotic appearance. A thorough evaluation and study with highly sensitive and specific diagnostic tests allowed an adequate diagnosis and treatment.

Background: Novel coronavirus has continued to spread throughout the world where there are other endemic diseases that have been a burden to public health for many years. As any infection, it was expected there could be coinfection between these. Tropical and subtropical countries are currently managing with dengue as peaks increase with shorter periods of time.

Aim: To summarize the evidence that exists in the co-infection related to SARS-CoV-2 and the dengue virus.

Method: We conducted a narrative review in data bases about reports of coinfection and misdiagnosis of SARS-CoV-2 and dengue virus given the fact that rainy season every year increase the prevalence of viral infections in endemic countries. Recent reports have even described positive cases in one of these infections that later resulted in false positive. A positive test for COVID-19 or dengue fever in endemic areas should not exclude the other infection.

Conclusion: From now on, these two should be considered as a differential diagnosis and this should raise public health concern for COVID-19 and dengue coinfection in endemic countries to reinforce promotion and prevention to communities to prevent these diseases.
