Acute tubal or aural catarrh, attributable probably the sudden reduction temperature in the air-lock. The cases rupture occurred most frequently in persons visiting the air-chamber for the first time in other cases, however, the accident was evidently due an actual tubal catarrh developed during the interval a few hours, between two periods labor. Only one case rupture was seen immediately after the injury presented the appearance a nearly vertical slit about two lines in length, in the posterior portion the membrane about a drop coagulated blood was found in the external meatus. Two or three cases purulent otitis media were thesis online treated in which the history pointed clearly a rupture, followed pain, discharge, In one case, several weeks standing, there was a polypoid growth protruding through the perforated membrane. The polypus rapidly retreated under the careful use solid chromic acid, applied upon the end a fine probe the perforation healed.
There was nothing peculiar in the cases simple catarrh some them were quite mild, others rather severe all did well under the usual methods treatment.
It currently reported, upon sufficiently trustworthy authority, that several cases partial deafness have been cured a the air-chamber. Such an exposure acts, course, as a powerful air-bath, and may sometimes suffice, overcome a tubal adhesion. It certainly not commended as a plan treatment. In a few cases severe pain has been felt in the region the frontal sinuses, first entering the air-chamber. This may explained supposing an obstruction from swelling the walls the passage from the sinus the middle meatus the nostril. The excess pressure upon theses and dissertations the surface and in the open cavities the body over that in the closed sinus, would doubtn less lead a speedy efrusion blood or serum within that cavity, giving rise probably a secondary trouble from distention, when the external pressure removed. Hremoptysis has also occurred, in one case, under the observation the writer. The subject the same in whom the recent rupture the membrana tympani was observed was a stranger visiting the works from motives curiosity. He entered the lock under the guidance a careless laborer, who admitted the condensed air rapidly as cause intense pain in the ears, ending in the rupture one the membranes. Frightened at this accident, sisted upon being released, and the air was let off as rapidly as had been admitted.
The haemoptysis occurred immediately upon his stepping out the lock was not large, and continued but a short time. subject before the British Association for the Advancement Science, at a recent meeting. We take the following from the London Medical Times and Gazelle Mr. McGordon said that after employing sewage, which might have professional custom essays been used fertilize the earth, in polluting the rivers which nature intended the source water-supply, spend hundreds thousands pounds in obtaining pure water from distant lakes and rivers but no sooner does this pure water cross our threshold than, either from ignorance, carelessness, or false notions economy, in many cases converted into a slow poison.
Medical and scientific men have been long impressed with the great danger health which caused the use leaden cisterns and pipes as a means storing and distributing water used for dietetic purposes but this danger has not forced itself sufficiently upon the attention the general public.
The cheapness and ductility lead for water conveyance have been allowed override the newsletter writing service dangers which are known arise from the action water upon This action uncertain and various but instances are numerous where its effects are positively and immediately injurious, that all who have turned their attention the subject have come the same conclusion need help writing history essay that the use lead should abolished as a material for the storage and conveyance water. No consideration, either is there a website that writes essays for you economy or convenience, should allowed prevail in the face important a danger. Dr. Lankester, from an examination the action the pure water supplied Manchester and this town, found in both instances that where the water had been allowed stand in leaden pipes there were proofs contamination with lead and mentions several remarkable cases diseases produced in households, which have come within the range his own observations.
