A Case Report of Bowel Perforation in a Gravid COVID-19 Patient.

Background: Bowel perforation in a pregnant patient with COVID-19 infection is a rarely reported complication. With the uncovering of the different treatment modalities and complications of this disease, this case highlights diagnostic and therapeutic dilemmas and limitations in a special population. .

[Chronic obstructive pulmonary disease and bronchiectasias].

Chronic obstructive pulmonary disease (COPD) and bronchiectasias are two of the most frequent and underdiagnosed diseases of the airways. The association between these two entities can be established from different points of view. On the one hand, because of their high prevalence, the co-occurrence of COPD and bronchiectasias in the same patient is not unusual.

[Cardiovascular comorbidity in COPD].

The presence of cardiovascular alterations in patients with chronic obstructive pulmonary disease (COPD) is no coincidence. Smoking, a risk factor for both entities, could partly explain the strength of the association; however, there are data that suggest that other determining factors such as systemic inflammation, oxidative stress, hypoxemia, endothelial dysfunction and even aging could also be involved. Prognosis is worse in patients with both entities.

Cell type accuracy of bronchial biopsy specimens in primary lung cancer.

Study Objectives: To evaluate the diagnostic accuracy of bronchial biopsy (BB) specimens in establishing the specific cell type in primary lung cancer (LC), and to study the influence of several factors on this accuracy.

Setting: Tertiary health-care center.

Patients: One hundred forty-six patients with LC diagnosed by BB specimens who underwent thoracotomy (T).
