Safety perception in the operating environment: The nurses' perspective versus that of the surgeons.

Background: Adverse effects due to surgery occur in 25% of patients, and the patient safety perception seems to differ between nurses and surgeons in the operating room (OR). This difference can be attributed to lack of communication. However, our hospital has not conducted any studies on patient safety climate (PSC) in the OR.

Post-vaccination SARS-CoV-2 axillary adenopathy. Differences with axillary metastases from breast cancer.

The differential diagnosis of the metastatic axillary lymphadenopathies of breast cancer with which they occur secondary to the Pfizer-BioNTech vaccine against COVID-19, is imperative. In a series of cases, we analyzed the characteristics of unilateral axillary lymphadenopathy in patients after Pfizer-BioNTech vaccination. Axillary lymphadenopathy were observed ipsilateral to the vaccination arm.

Inverse radiotherapy planning in reconstructive surgery for breast cancer.

Background: Post-mastectomy radiotherapy reduces the risk of local-regional relapse and distant disease, and increases global survival in women with axillary involvement. With the new reconstruction techniques and increasing use of directed external radiotherapy, immediate reconstruction can be performed with good cosmetic results and low complication rates.

Materials And Methods: Observational study with consecutive sampling conducted in patients undergoing reconstructive surgery for breast cancer, between 2010 and 2016, with a 12-months minimum follow-up period.

Factors predicting local relapse and survival in patients treated with surgery for breast cancer.

Background: Assessment of local relapse in patients treated with surgery for breast cancer.

Materials And Methods: This observational study included 673 patients treated with surgery for breast cancer between 2005 and 2010, who were monitored for a 7-year minimum follow-up period. The study was concluded on 2017 and yielded a total of 31 cases of local relapse.

[Uso de los valores de hormona paratiroidea intranodular obtenidos por punción con aguja fina como factor predictivo de hipoparatiroidismo posoperatorio].

Objetivo: Análisis de los valores de hormona paratiroidea (PTH) intranodular obtenidos por punción con aguja fina como factor predictivo de hipoparatiroidismo posoperatorio.

MÉtodo: De los 157 pacientes a los que se realizó la medición de la PTH intranodular, se estudiaron 37 que fueron intervenidos quirúrgicamente, estableciendo 15 variables para analizar: edad, sexo, tiempo de evolución, tamaño, cirugía de tiroides asociada, tratamiento preoperatorio con calcimiméticos, litiasis renal, densitometría ósea, aclaramiento de creatinina, calcio y PTH preoperatorios, PTH determinada tras punción con aguja fina, descenso de la PTH intraoperatoria, calcio posoperatorio y malignidad de la tumoración. Estas se compararon con la prueba de ji al cuadrado o el test exacto de Fisher, siendo significativa una p < 0.
