Abstract

This study aimed to describe the prevalence of high‐risk human papillomavirus (HR‐HPV) types in the anal canal in a cohort of people living with HIV (PLWHIV) with a history of malignancy. Setting: Referral tertiary care hospital for adult patients with cancer. Methods: We reviewed data of patients from the AIDS Cancer Clinic on antiretroviral therapy in chronic control who were consecutively referred for high‐resolution anoscopy (HRA), where they underwent anal evaluation, collection of specimens for anal cytology and anal human papillomavirus (HPV) followed by HRA with directed biopsy if needed. Results: A total of 155 patients were included; 149 (96.1%) were men, all of them men who have sex with men (MSM); the median age was 39 (IQR 32‐47) years; 105 (67.7%) with Kaposi sarcoma, 40 (25.8%) with non‐Hodgkin lymphoma and 10 (6.4%) with other neoplasms; only 7 (4.5%) had active cancer. The prevalence of HR‐HPV infection was 89% (n=138) (95% CI 83–93) with at least one HR‐HPV infection, and 62% (96) had coinfection with at least two types; the median HR‐HPV types of coinfection were 3 (IQR 2–4). The number of patients infected with HPV 16 was 64 (41.3%, 95% CI 33.8–49.3), HPV 18 was 74 (47.7%, 95% CI 39.9–55.7) and with both 35 (22.6%). Some 59 patients (38%) had high‐grade squamous intraepithelial lesions (HSIL) and 49 (31.6%) had low‐grade squamous intraepithelial lesions (LSIL). The prevalence of HR‐HPV and HSIL among patients aged ≤35 and >35 years was the same. Conclusions: In this cohort of PLWHIV with a history of malignancy we found a high prevalence of HR‐HPV 16 and 18 and anal HSIL, even in persons aged ≤35 years. These data highlight the importance of anal cancer screening in PLWHIV and history of malignancy. [ABSTRACT FROM AUTHOR]

Abstract

Acinetobacter pittii has increasingly been associated with several types of hospital-acquired severe infections. Genes implicated in carbapenem resistance, tigecycline resistance, or genes encoding extended spectrum cephalosporinases, such as blaADC, are commonly found in isolates implicated in these infections. A. pittii strains that are pandrug resistant have occasionally been identified. Food for human consumption, animals and plants are environmental sources of this pathogen. An alarming situation is that A. pitti has been identified as responsible for outbreaks in different regions worldwide. In this study, 384 genomes of A. pittii were analyzed, comprising sequences from clinical and non-clinical origins from 32 countries. The objective was to investigate if clinical strains possess genetic traits facilitating hospital adaptation. Results indicate significant genomic variability in terms of size and gene content among A. pittii isolates. The core genome represents a small portion (25-36%) of each isolate's genome, while genes associated with antibiotic resistance and virulence predominantly belong to the accessory genome. Notably, antibiotic resistance genes are encoded by a diverse array of plasmids. As the core genome between environmental and hospital isolates is the same, we can assume that hospital isolates acquired ARGs due to a high selective pressure in these settings. The strain's phylogeographic distribution indicates that there is no geographical bias in the isolate distribution; isolates from different geographic regions are dispersed throughout a core genome phylogenetic tree. A single clade may include isolates from extremely distant geographical areas. Furthermore, strains isolated from the environment or animal, or plant sources frequently share the same clade as hospital isolates. Our analysis showed that the clinical isolates do not already possess specific genes, other than antibiotic-resistant genes, to thrive in the hospital setting. [ABSTRACT FROM AUTHOR]

Abstract

Kaposi sarcoma (KS) arises in the context of 4 epidemiologic-clinical settings: Classic, endemic, epidemic, and iatrogenic; the most serious types are endemic and epidemic, and visceral involvement occurs mostly in the latter. Several morphological variants of KS have been described, of which the anaplastic one is highly aggressive. We report the case of an anaplastic KS arising from the ascending colon in a 32-year-old human immunodeficiency virus (HIV)-positive male patient with a 6-year history of multiple mucocutaneous KS. Anaplastic KS is most frequent in endemic and classic settings; there are ten cases of anaplastic KS reported in HIV-positive male patients. There is now strong evidence that KS is a clonal neoplasm characterized by chromosomal instability at the molecular level. According to the morphological spectrum and contemporary hypotheses of oncogenesis, conventional KS should be considered an incipient endothelial neoplasia, multiple or single, and anaplastic KS, the fully developed stage of the malignant neoplasm.

Abstract

ObjectivesTo describe patterns of transmissible infections, chronic illnesses, socio-demographic characteristics and risk behaviors in Mexico City prisons, including in comparison to the general population, to identify those currently needing healthcare and inform policy.Materials and methodsA cross-sectional study among 17,000 prisoners at 4 Mexico City prisons (June to December 2010). Participation was voluntary, confidential and based on informed consent. Participants were tested for HIV, Hepatitis B & C, syphilis, hypertension, obesity, and, if at risk, glucose and cholesterol. A subset completed a questionnaire on socio-demographic characteristics and risk behaviors. Positive results were delivered with counseling and treatment or referral.Results76.8% (15,517/20,196) of men and 92.9% (1,779/1,914) of women participated. Complete data sets were available for 98.8%. The following prevalence data were established for transmissible infections: HIV 0.7%; syphilis: Anti-TP+/VDRL+ 2.0%; Hepatitis B: HBcAb 2.8%, HBsAg 0.15%; Anti-HCV 3.2%. Obesity: 9.5% men, 33.8% women. Compared with national age- and sex-matched data, the relative prevalence was greater for HIV and syphilis among women, HIV and Hepatitis C in men, and all infections in younger participants. Obesity prevalence was similar for women and lower among male participants. The prevalence of previously diagnosed diabetes and hypertension was lower. Questionnaire data (1,934 men, 520 women) demonstrated lower educational levels, increased smoking and substance use compared to national data. High levels of non-sterile tattooing, physical abuse and histories of sexual violence were found.ConclusionThe study identified that health screening is acceptable to Mexico City prisoners and feasible on a large-scale. It demonstrated higher prevalence of HIV and other infections compared to national data, though low rates compared to international data. Individual participants benefited from earlier diagnosis, treatment and support. The data collected will also enable the formulation of improved policy for this vulnerable group.

Abstract

In this study, we report the presence of a female Amblyomma americanum tick attached to a former resident of the East Coast of the United States who moved to Mexico city. The amplification and sequencing of gene fragments of the 16S-rDNA and cytochrome c oxidase subunit 1 corroborated the identification of the species of the tick. Additionally, the presence of DNA of Rickettsia amblyommatis was confirmed. This work is the first report of an exotic tick of the genus Amblyomma in a traveler from the US to Mexico and represents the second record of an imported tick attached to humans in Mexico.

Abstract

Introduction: High HHV-8 viral load (VL) in Kaposi Sarcoma (KS) has been associated with Severe Immune Reconstitution Inflammatory Syndrome (Severe-IRIS-KS), which can occur after initiating cART, and leads to high mortality, particularly in patients with pulmonary involvement. We investigate if valganciclovir (as an anti-HHV-8 agent) initiated before cART reduces the mortality associated with Severe-IRIS-KS and the incidence of Severe-IRIS-KS. Methods: Open-label parallel-group randomized clinical trial in AIDS cART naïve patients with disseminated KS (DKS) as defined by at least two of the following: pulmonary, lymph-node, or gastrointestinal involvement, lymphedema, or ≥30 skin lesions. In the experimental group (EG), patients received valganciclovir 900 mg BID four weeks before cART and continued until week 48; in the control group (CG), cART was initiated on week 0. Non-severe-IRIS-KS was defined as: an increase in the number of lesions plus a decrease of ≥one log10 HIV-VL, or an increase of ≥50cells/mm3 or ≥2-fold in baseline CD4+cells. Severe-IRIS-KS was defined as abrupt clinical worsening of KS lesions and/or fever after ruling out another infection following cART initiation, and at least three of the following: thrombocytopenia, anemia, hyponatremia, or hypoalbuminemia. Results: 40 patients were randomized and 37 completed the study. In the ITT analysis, at 48 weeks, total mortality was the same in both groups (3/20), severe-IRIS-KS attributable mortality was 0/20 in the EG, compared with 3/20 in the CG (p = 0.09), similar to the per-protocol analysis: 0/18 in the EG, and 3/19 in the control group (p = 0.09). The crude incidence rate of severe-IRIS-KS was four patients developed a total of 12 episodes of Severe-IRIS-KS in the CG and two patients developed one episode each in the EG. Mortality in patients with pulmonary KS was nil in the EG (0/5) compared with 3/4 in the CG (P = 0.048). No difference was found between groups in the number of non-S-IRIS-KS events. Among survivors at week 48, 82% achieved >80% remission. Conclusions: Although mortality attributable to KS was lower in the EG the difference was not statistically significant.

Abstract

OBJETIVO: Describir los resultados de diez años de vigilancia de infecciones intrahospitalarias (II) en un centro oncológico. MATERIAL Y MÉTODOS: Es un estudio descriptivo, retrospectivo, del programa de vigilancia del Comité de Vigilancia y Control de Infecciones Intrahospitalarias del Instituto Nacional de Cancerología, realizado en 1997. Se utilizaron los criterios de infección intrahospitalaria por sitio propuestos por el Centro para la Prevención y el Control de Enfermedades de Atlanta, Georgia, de Estados Unidos de América, en 1972. De junio de 1986 a diciembre de 1996, se estudiaron 62 733 egresos. La vigilancia se realizó mediante la revisión de los expedientes de pacientes con fiebre, de aquellos que reciben antibióticos y de posoperados en los pisos de hospitalización y revisión de cultivos. Se calcularon las tasas de II por episodios/100 egresos. RESULTADOS: La tasa de infecciones intrahospitalarias por 100 egresos fue de 4.4 en 1986; 7.7, en 1987; 8.1, en 1988; 5.9, en 1989; 4.6, en 1990; 5.1, en 1991; 4.3, en 1992; 5.4, en 1993; 7.6, en 1994; 7.1, en 1995, y 8.5, en 1996. El germen más frecuentemente aislado en las II fue Escherichia coli. Los aislamientos de hongos y los de enterococo se incrementaron en casi siete veces desde 1987. CONCLUSIONES: Se observó un incremento en la tasa de infecciones hospitalarias en los últimos cuatro años. Al menos dos factores contribuyeron a esta tendencia: la aplicación de un sistema de vigilancia más experimentado, el cual hizo que disminuyera el subregistro, y el aumento real en la frecuencia de tales infecciones.

Abstract

OBJECTIVE: To determine amount of syringes used in the hospital and extent of contact with blood and body fluids of these syringes. MATERIAL AND METHODS: Syringe use was surveyed at a tertiary care center for one week; syringes were classified into the following four categories according to use: a) contained blood; b) contained other body fluids (urine, gastric secretion, cerebrospinal fluid, wound drainage); c) used exclusively for drug dilution and application in plastic intravenous (IV) tubes, and d) for intramuscular (IM), subcutaneous (SC), or intradermic (ID) injections. RESULTS: A total of 7 157 plastic disposable syringes was used; 1 227 (17%) contained blood during use, 346 (4.8%), other body fluids, 5 257 (73%) were used exclusively for drug dilution and application in plastic IV lines, and 327 (4.5%) were utilized for IM, SC, or ID injections. An estimated 369 140 syringes used annually, or eight syringes per patient per in-hospital day. All syringes were disposed of as regulated medical waste, in observance of the law. CONCLUSIONS: There is an urgent need to review recommendations for medical waste management by both international agencies and local governments, based on scientific data and a cost-benefit analysis, to prevent resource waste and further environmental damage.

Abstract

OBJETIVO: Describir un brote por Pseudomonas aeruginosa, en el área de atención ambulatoria de herida quirúrgica, en pacientes posmastectomizadas. MATERIAL Y MÉTODOS: Entre el 13 de marzo y el 18 de mayo de 2000 se definió como caso a las pacientes del Instituto Nacional de Cancerología de la Ciudad de México, mastectomizadas con infección quirúrgica por P aeruginosa resistente a ciprofloxacina y gentamicina. Se tomaron cultivos de los antisépticos, del material de curaciones, del agua y del personal de salud. Se efectuó un análisis de casos y controles. RESULTADOS: Se identificaron 13 infecciones tardías del sitio quirúrgico por P aeruginosa. La Pseudomona se aisló de las narinas de la enfermera y de las gasas que ella misma colocaba sobre la mesa de mayo, pero no de los paquetes de gasas cerrados del área de curaciones ambulatoria de tumores mamarios. El 14 de abril de 2000 se transfirió a la enfermera a otra área y se instauraron medidas estrictas para el control de infecciones. Después de esta fecha se diagnosticaron cuatro casos más. La radioterapia fue el único factor de riesgo asociado con la infección (RM=5.1, IC 95%=1.1-28.4). CONCLUSIONES: El brote probablemente estuvo causado en un inicio por una fuente común y se extendió por infección cruzada entre las pacientes. Las prácticas deficientes detectadas en el manejo de heridas y drenajes condujo a instaurar medidas preventivas específicas.

Abstract

OBJETIVO. Conocer la frecuencia de infecciones quirúrgicas con un programa prospectivo de vigilancia de cirugías y seguimiento postegreso, en el Instituto Nacional de Cancerología, que es un hospital de tercer nivel de la Ciudad de México. MATERIAL Y MÉTODOS. Durante 18 meses se captaron y se vigilaron todas las cirugías efectuadas en el hospital. Se calcularon las razones (por 100 cirugías) de infecciones de herida quirúrgica (IHQX) por servicio y por el grado de contaminación bacteriana. Se utilizaron las definiciones de IHQX del Centro para la Prevención y el Control de las Enfermedades de Estados Unidos de América (1992). RESULTADOS. Se vigilaron 3 372 cirugías. Trescientos trece casos se infectaron: 140 (44.7%) fueron incisionales superficiales; 137 (43.7%), incisionales profundas, y 36 (11.5%), de órganos y espacios. La frecuencia de IHQX fue de 9.28%; para las cirugías limpias, limpias-contaminadas, contaminadas y sucias fue de 7.35, 10.5, 17.3 y 21.5%, respectivamente. La frecuencia de infecciones por servicio fue: gastroenterología, 14.13%; tumores de mama, 11.08%; piel y partes blandas, 10.98%; ginecología, 9.06%; urología, 7.38%; cabeza y cuello, 7.13%, y neumología, 1.81%. La IHQX ocurrió en promedio a los 11.6±6.23 días; 85 casos (27.16%) se diagnosticaron mientras el paciente estaba hospitalizado, y 228 (72.84%), después del egreso del paciente. Se obtuvo algún cultivo en 134 (42.8%) casos. Los gérmenes más comunes fueron: E. coli, 38 (22.5%); estafilococo coagulasa negativo, 23 (13.6%); Pseudomonas sp., 22 (13%); S. aureus, 16 (9.4%), y enterococos,13 (7.7%). CONCLUSIONES. La vigilancia prospectiva de las cirugías con un seguimiento por 30 días aumentó hasta en 400% la posibilidad de detectar una IHQX. La frecuencia de IHQX en las cirugías limpias y limpias-contaminadas se encuentra por arriba de lo informado.
