Observational Study
General ward and pneumonia size as predictors of noninvasive ventilation failure.
Shortage of intensive care beds has led to more frequent use of noninvasive ventilation (NIV) outside respiratory units, and data on NIV efficacy and safety on general wards is lacking. ⋯ Patients with consolidation on chest X-ray and patients treated with NIV outside of dedicated respiratory units are at a higher risk for NIV failure.

Polycystic ovary syndrome is the most common endocrinopathy in women of reproductive-age. Therapy for those who want to get pregnant involves ovulation induction using clomiphene citrate, metformin, letrozole and gonadotropins. ⋯ This retrospective study demonstrated the advantages of the use of letrozole over clomiphene citrate in combination with metformin in moderately obese patients with polycystic ovary syndrome who are resistant to stimulation with clomiphene citrate alone.

Intramural hematoma of the aorta presents potentially fatal condition developing as a result of a vasa vasorum rupture. It is a major risk factor for developing a frank aortic dissection. ⋯ Intramural hematoma is not a common event, but it is potentially a fatal one. Open surgery in patients with an intramural hematoma is an effective treatment strategy, although percutaneous endovascular treatment options are being described.

Differences between the tooth and implant response to load can lead to many biological and technical implications in the conditions of occlusal forces. ⋯ Application of the resilient TSA abutment results in more equal distribution of stress and deformations in the bone tissue under vertical forces. These values are many times lower than in the model with the non-resilient abutment.

Historical Article
[Treatment by bloodletting in the past and present].
Therapeutic bloodletting has been practiced at least 3000 years as one of the most frequent methods of treatment in general, whose value was not questioned until the 19th century, when it was gradually abandoned in Western medicine, while it is still practiced in Arabic and traditional Chinese medicine. ⋯ Bloodletting is still indicated for a few indications such as polycythemia, haemochromatosis, and porphyria cutanea tarda, while leeches are still used in plastic surgery, replantation and other reconstructive surgery, and very rarely for other specific indications.
