Cáncer de mama en mujeres adultas mayores, características clínicas e histopatológicas y resultados del tratamiento con intención curativa / Characteristics and results of breast cancer in elderly females treated with curative inten

Background: Aging is the main risk factor to acquire breast cancer (BC). Nevertheless BC in elderly patients is sub-represented in clinical trials. Aim: To describe the clinical characteristics and long term treatment results of localized BC in older women. Material and Methods: Review of medical records of 65 women aged 70 to 88 years, with localized BC, treated with surgery, postoperative radiotherapy or systemic therapy at a Clinical Hospital in Chile. Results: The presence of symptoms or abnormal findings on physical examination were the main reasons for consulting in 65% of cases. Compared with tumors detected on physical examination, those detected using screening mammogram were smaller and were in stage 1 with a higher frequency (18 and 59% respectively, p < 0.01). The pathological type was luminal in 80% of cases. Overall survival was better for luminal pathological type. All patients completed radiotherapy without interruptions developing minor acute toxicity. The most common co-morbidity was high blood pressure occurring in 46% of patients. Thirteen percent of patients had three or more co-morbidities. After a median follow up of 7 years, 23 (35%) patients had died and the cause of death was BC in 43% of cases. Two patients died of lung cancer. No patient had a local breast relapse. Conclusions: Screening mammogram in older women detected smaller tumors and it was associated with a better survival. BC is the ultimate cause of death in approximately half of cases.

Does side matter? Effect of single lung transplant laterality on outcomes.

BACKGROUND: Previous works have suggested that recipients of left single lung transplant (SLT) have a worse outcome than those receiving right SLT. We evaluated the effect of SLT laterality on outcomes. METHODS: We performed a retrospective study of SLT recipients followed up at our center. One hundred and nineteen patients were reviewed (53 left SLT, 66 right SLT). We extracted data on lung function, exercise capacity, relative graft perfusion, airway complications, acute rejection episodes, infections and mortality. RESULTS: There was no significant difference between right and left lung recipients with regard to baseline demographic and physiological characteristics. Lung function, exercise capacity and relative graft perfusion improved in both groups following transplantation. We observed a higher graft perfusion in right-sided grafts compared to left ( P = 0.048). There was no significant difference between the two groups in physiological outcomes, rejection or infection episodes, the presence of chronic rejection or mortality. We observed a statistically higher need for bronchial stent insertion during early follow-up amongst the left lung recipients ( P = 0.022). CONCLUSIONS: Both right and left lungs are equally suitable for transplantation. The left-sided bronchial anastomosis may be more vulnerable to complications.

Eficacia de la dexametasona en sindrome hellp

Después de la administración de dexametasona (vía EV en dosis de 10 mg. cada 12 horas) a una paciente de 26 semanas de gestación, hipertensa crónica con preeclampsia sobreagregada y síndrome Hellp, se aprecia estabilización y disminución de enzimas hepáticas (principalmente SGOT/AST), LDH y aumento de recuento de plaquetas, no observándose variaciones en los niveles de ácido úrico, creatinuria, proteinuria y calciuria.
