ABSTRACT
RESUMEN La protuberancia coriónica (del inglés chorionic bump) es una condición que involucra al saco gestacional y que puede ser visualizada en la ecografía de primer trimestre. Ha sido descrita como una convexidad irregular que protruye hacia el saco gestacional y que probablemente corresponda a la formación de un hematoma en la superficie coriodecidual. Nosotros reportamos los hallazgos y el seguimiento ecográfico de un caso, junto con una revisión de la literatura.
SUMMARY Chorionic bump is a condition that involves the gestational sac and can be viewed during the first-trimester ultrasound scan. It has been described as an irregular convexity protruding into the gestational sac and probably corresponds to the formation of a hematoma within the choriodecidual surface. We reported both the sonographic findings and follow-up of a case, along with a review of the literature.

BACKGROUND: An ultraviolet C (UVC) decontamination device that delivers germicidal UVC radiation to the soles of shoes has become available recently. AIM: To demonstrate that shoe soles can be vectors for healthcare-associated infection, and to investigate if a UVC shoe sole decontamination device would decrease this risk effectively. METHODOLOGY: Three bacterial strains (Staphylococcus aureus, Enterococcus faecalis and Escherichia coli) and a non-toxigenic strain of Clostridium difficile were spiked on to standardized rubber-soled shoe soles and then selected at random for UVC exposure or no UVC exposure. Experiments were performed to test the efficacy of the UVC device to decontaminate shoe soles and flooring. E. faecalis was spiked on to shoes to assess colonization of a simulated healthcare environment and patient. RESULTS: The UVC device decreased shoe sole contamination significantly for all tested bacterial species, and decreased floor contamination significantly for all floor types and species tested (P<0.01 for all experiments). The log10 reduction was the highest for E. coli (mean±standard deviation 2.6±0.79), followed by E. faecalis (2.19±0.68), S. aureus (1.74±0.88) and C. difficile (0.42±0.54) (P<0.0001 for all analyses). Exposure of shoe soles to the UVC device decreased contamination significantly (mean log10 reduction 2.79±1.25; P<0.0001). Proportions of samples from furniture, bed and patient dummy samples decreased from 96-100% positive in controls to 5-8% positive in UVC device experiments (P<0.0001 for all analyses). CONCLUSION: A UVC decontamination device was shown to reduce the colony-forming unit counts of relevant pathogenic organisms from shoe soles with subsequent decreased colonization of floors, healthcare equipment, furniture, beds and a patient dummy.

Background: Laparoscopic adrenal approach was introduced in 1992 and is becoming the surgical method of choice for several adrenal diseases. Aim: To report the initial Chilean experience in laparoscopic adrenalectomy. Material and methods: A retrospective review of 17 patients subjected to the surgical procedure by the authors. Results: The preoperative diagnosis were adenomas (8 patients), pheochromocytoma (3), cystic lesions (2), adrenal metastases (2), hyperaldosteronism (1) and a pituitary Cushing (1). The average lesion size was 5.4 cm, the operative time 2.5 hours and the hospital stay 2.5 days. Eight patients were discharged in less than 48 hours. Pain was managed with non steroidal anti-inflammatory drugs in 14 patients. One subject required conversion to open surgery. Transfusions were required in complex cases witha diaphragmatic hamartoma, Cushing disease and in a combined adrenal and renal resection. One patient had to be re admitted due to a pancreatic pseudo cyst that was drained percutaneously. There have been no recurrences after a mean follow up of 2 years. Conclusions: This early experience with laparoscopic adrenalectomy shows good results. A good patient selection and experience with advanced laparoscopic surgery are requisites for a successful use of this surgical technique

La frecuencia con que se aisla haemophilus influenzae en infecciones maternas y neonatales, particularmente en partos prematuros, ha aumentado. Se describen tres casos clínicos de madres con antecedentes de rotura de membranas reciente y de hasta 24 horas, en cuyo líquido amniótico se aislaron cepas no capsuladas de haemophilus influenzae de serotipo no b, una de ellas biotipo II (las otras dos no fueron tipificadas). Los recién nacidos pesaron respectivamente 1.670, 950 y 1.680 g. En el primer caso, la madre y el recién nacido fueron tratados con antibióticos y no presentaron signos de infección sistémica. En el segundo caso la madre no recibió antibióticos al ingresar, a pesar de haberlo hecho con fiebre, sino hasta el puerperio inmediato; el niño fue afectado por septicemia a haemophilus influenzae, neumonía, dificultad respiratoria severa y hemorragia intracraneana, falleciendo a la edad de 12 dias. En el tercer caso, la madre recibió antibióticos sólo en el puerperio (por fiebre en el período expulsivo), pero el niño desde el nacimiento; en éste se aisló haemophilus influenzae del unto caseoso, sin signos de infección sistémica. El examen microbiológico del líquido amnióticop en mujeres embarazadas con rotura prematura de membranas puede ser de gran utilidad para manejar adecuadamente el riesgo de infecciones perinatales por estos agentes

Ciento un pacientes portadoras de una esterilización tubaria, fueron sometidas a recanalización por microcirugía. En 84 pacientes, se logró embarazo, lo que representó un éxito de 83,2. En el primer año de seguimiento, el 79,8% había conseguido el embarazo. La incidencia de Embarazo tubario fue de 9,5%. Se destaca que con una técnica de microcirugía adecuada, efectuada por expertos, se logran excelentes resultados en la reversión de la esterilización de trompas
