RESUMO

The aim of this study was to evaluate the association between prostate cancer (PCa) and Human papillomavirus (HPV) infection in the Mexican population. We studied 356 paraffin-embedded tissues from unrelated Mexican men with PCa or benign prostatic hyperplasia (BPH), with the latter serving as control. HPV detection was performed by polymerase chain reaction (PCR) using universal primers, and viral genotypes were detected using sequencing or multiplex PCR. Light microscopy analyses enabled the identification of koilocytes in samples subsequently analyzed for HPV detection by in situ PCR and for p16-INK4A expression by immunohistochemistry. The results showed that high risk- (HR) HPVs were detected in 37/189 (19.6%) PCa specimens compared to 16/167 (9.6%) of BHP specimens (odds ratio 2.3; 95% CI= 1.2 to 4.3; p=0.01). These data suggest HR-HPV may play a role in PCa. HPV 52 and 58 were the most frequent genotypes (33 and 17%, respectively) detected in the population studied. Koilocytes were detected in all in situ PCR-HPV-positive samples, representing a pathognomonic feature of infection, and we observed the overexpression of p16-INK4A in HPV-positive samples compared to HPV-negative samples, indirectly suggesting the presence of HR-HPV E7 oncoprotein. These results suggest that HPV infection plays an important role in prostate cancer development.

RESUMO

Resumen: Introducción: El objetivo de este estudio es determinar los procedimientos quirúrgicos más frecuentemente realizados en el Centro Médico Naval, un Centro Médico de Tercer Nivel. Material y métodos: Se realizó un estudio observacional, exploratorio, descriptivo, trasversal y retrospectivo incluyendo todas las cirugías realizadas del 01 de enero de 2015 al 31 de julio de 2019, consultando los registros del quirófano y los expedientes electrónicos. Resultados: Se registraron 25,114 cirugías, con un promedio anual de 5,527 procedimientos y de 16 procedimientos diarios (rango de 2 a 25). Las especialidades que más cirugías realizaron fueron cirugía general, ortopedia, ginecoobstetricia y oftalmología. Las principales cirugías realizadas fueron la facoemulsificación de catarata con colocación de lente intraocular, endoscopías, cesáreas, colecistectomía laparoscópica, atención del trabajo de parto, reducción abierta con fijación interna de fracturas, apendicectomía abierta, hernioplastía inguinal y lavados quirúrgicos. El 59% de las cirugías se realizó en mujeres. El rango de edad de los pacientes fue desde recién nacido hasta los 101 años, estando la mayoría entre los 53 y 72 años. Conclusiones: El Centro Médico Naval destina la mayoría de los recursos de su quirófano para la atención obstétrica (cesárea y trabajo de parto), la atención de padecimientos crónico-degenerativos (cirugía de catarata, y endoscopías), atención de accidentes (reducción de fracturas y lavados quirúrgicos) y la resolución de padecimientos abdominales agudos como la apendicitis y la colecistitis.


Abstract: Introduction: The study objective was to determine the most frequently surgical procedures at the Naval Medical Center, a third level medical center. Material and methods: An observational, exploratory, descriptive, cross-sectional and retrospective study was conducted including all surgeries performed from January 1, 2015 to July 31, 2019, reviewing the surgical records and patient electronic files. Results: 25,114 surgeries were registered, with an annual average of 5,527 procedures and 16 daily procedures (range from 2 to 25). General surgery, orthopedics, gynecoobstetrics and ophthalmology were the specialties with the most amount of surgeries. The main surgeries were cataract phacoemulsification with intraocular lens placement, endoscopies, caesarean sections, laparoscopic cholecystectomy, labor delivery, open reduction with internal fracture fixation, open appendectomy, inguinal hernioplasty and surgical washes. 59% of the surgeries were performed in women. The age range of the patients was from newborn to 101 years, with most patients between 53 and 72 years. Conclusions: The naval medical center spend surgical resources for obstetric care (caesarean section and labor), care of chronic degenerative diseases (cataract surgery, and endoscopy), accident care (fracture reduction and surgical washes) and the resolution of acute abdominal conditions such as appendicitis and cholecystitis.
