Primary Cauda Equina T-Cell Lymphoblastic Lymphoma.

Background: T-cell lymphoblastic lymphoma (T-LBL) is a rare and aggressive form of non-Hodgkin lymphoma. This report describes, to our knowledge, the first adult case of a primary cauda equina T-LBL. Treatment consists of multiagent chemotherapy, and surgical removal of T-LBL does not improve outcome.

Vitamin A and beta (β)-carotene supplementation for cystic fibrosis.

Background: People with cystic fibrosis (CF) and pancreatic insufficiency are at risk of a deficiency in fat-soluble vitamins, including vitamin A. Vitamin A deficiency predominantly causes eye and skin problems, while excessive levels of vitamin A can harm the respiratory and skeletal systems in children and interfere with the metabolism of other fat-soluble vitamins. Most CF centres administer vitamin A as supplements to reduce the frequency of vitamin A deficiency in people with CF and to improve clinical outcomes such as growth, although the recommended dose varies between different guidelines.

Comparison of bronchoscopy and bronchoalveolar lavage findings in three types of suppurative lung disease.

Background: Endobronchial suppuration is present in children with protracted bacterial bronchitis (PBB), bronchiectasis, and cystic fibrosis (CF). However, no studies have directly compared bronchoscopy and bronchoalveolar lavage (BAL) findings across these conditions within a single center using the same techniques and with shared community pathogens.

Aim: To determine; (i) the bronchoscopic findings and BAL microbiology and cellularity among children with these conditions and; (ii) the relationship between bacterial pathogens, airway cellularity and aberrant macroscopic bronchoscopic findings.
