RESUMO
Pneumocephalus is the pathologic collection of air in the intracranial cavity. In sufficient volumes, it can contribute to symptoms ranging from headaches to death. For conservative treatment, oxygen use is commonplace. Although this is an accepted tenet of clinical practice, it is not necessarily founded on robust trials. An electronic search of databases EMBASE and MEDLINE and the Cochrane Library was undertaken as per the 2020 Preferred Reporting Items of Systematic Reviews and Meta-Analyses (PRISMA) statement. Three articles were included. Although the modes of oxygen delivery were heterogenous (non-rebreather versus endotracheal versus hyperbaric chamber), all studies concluded favorably on the use of oxygen therapy for increased reabsorption of pneumocephalus.

Necropsy fat samples from subjects living in Rangoon area have been analyzed by TLC for their DDT, DDE and endrin contents. DDT and DDE were found in all cases; endrin, in excess of 0.2 ppm, was detected in two cases only. There was no significant difference in DDT, DDE or total DDT content in various age groups or between males and females. Levels of these residues were found to be low when compared with those observed in the populations living in Calcutta and Bangkok. This may be due to limited use of DDT and endrin for the control of agricultural pests in Burma.
