Adherence of North-African Pulmonologists to the 2017-Global Initiative for Chronic Obstructive Lung Disease (GOLD) Pharmacological Treatment Guidelines (PTGs) of Stable Chronic Obstructive Pulmonary Disease (COPD).

Background: No previous study has investigated the adherence rate of North-African pulmonologists to the 2017-GOLD PTGs.

Aims: To investigate the adherence rate of Tunisian pulmonologists to the 2017-GOLD PTGs and to identify the barriers to their adherence.

Methods: This was a cohort study involving clinically stable COPD patients who presented to a pulmonology outpatient consultation.

Pulmonary Barotrauma Including Huge Pulmonary Interstitial Emphysema in an Adult with Status Asthmaticus: Diagnostic and Therapeutic Challenges.

Introduction: Pulmonary interstitial emphysema is a rare finding defined as abnormal air collection inside the lung interstitial tissues. Described more frequently in ventilated new-borns, pulmonary interstitial emphysema is an uncommon barotrauma-related complication in adults. Management and clinical sequelae are poorly described.

Cerebral Vasculitis Complicating Pneumococcal Meningitis.

Introduction: Cerebral vasculitis is an uncommon life-threatening complication of community-acquired bacterial meningitis.

Patient And Methods: We report the case of a 64-year-old woman with pneumococcal meningitis who developed parainfectious vasculitis causing ischaemic brain damage. Cerebral magnetic resonance imaging (MRI) confirmed the diagnosis.

Airway management: induced tension pneumoperitoneum.

Pneumoperitoneum is not always associated with hollow viscus perforation. Such condition is called non-surgical or spontaneous pneumoperitoneum. Intrathoracic causes remain the most frequently reported mechanism inducing this potentially life threatening complication.

Evasion of Cell Senescence Leads to Medulloblastoma Progression.

How brain tumors progress from precancerous lesions to advanced cancers is not well understood. Using Ptch1(+/-) mice to study medulloblastoma progression, we found that Ptch1 loss of heterozygosity (LOH) is an early event that is associated with high levels of cell senescence in preneoplasia. In contrast, advanced tumors have evaded senescence.

Allergen specific immunotherapy induced multi-organ failure.

Allergen specific immunotherapy (ASI) is a well-documented treatment for allergic asthma, rhinitis and allergy to bee venoms. Immunotherapy with subcutaneous injections of allergens extracts has proved beneficial in reducing symptoms of allergic rhinitis and asthma. Side effects due to specific immunotherapy in short term have been largely documented.
