The combination of vomiting, choking, inanition, and obvious hunger in a newly born infant such as he describes is apparently produced as the result of pharyngeal or oesophageal malformation and nothing eise. Curious cases of choking induced by the swallowing of fluids have been described as occurring in the adult but here the causes are of different and diverse nature. The late Dr. J. S. Bristowe discusses such cases in his volume on Diseases of the Nervous System under the heading, "A Peculiar Form of Choking caused mainly by Swallowing Fluids." He also mentions an ingenious method of discovering the site of an abnormal communication between the air and food passages. The method consists in passing an cesophageal tube into the stomach and administering fluid through it whilst it is gradually withdrawn until the point is reached at which choking occurs. It is quite obvious, however, that in the case of the infants above men- tioned the choking is due to overflow of the contents of the pouch above the stricture into the rima glottidis, the abnormal tracheal communication being below and not above the site of occlusion. Mr. Thomas indicates, and we think very properly, gastrostomy as the proper operation, combined with rectal feeding. The difficulties of any direct operation on the oesophagus must necessarily be almost insuperable and, moreover, in some instances the site of the fistula is as low down as the main bronchus. Any inter- ference with the trachea at once increases the risks of broncho-pneumonia, risks which, from the nature of the choking, are already very great. These malformations have been extensively discussed by pathologists. They are men- tioned and illustrated by Mr. J. Bland-Sutton in his work on Tumours and are discussed in a masterly manner by Mr. S. G. Shattook in the forty-first volume of the Transactions of the Pathological Society of London. Mr. Shattock’s article will well repay perusal by those interested in the subject. He ascribes the malformations to the mechanical influence of the lung outgrowth from the primitive intestinal tube and brings forward considerable evidence in support of his con- tentions. Incidentally also he deals with certain malforma- tions of the aorta which may have a somewhat similar mechanical origin. - TICK FEVER. THE Treasury Department has issued from the Hygienic Laboratory Bulletin No. 14, by Dr. John F. Anderson, past assistant surgeon and assistant director, Hygienic Laboratory, United States Public Health and Marine Hospital Service (Washington, 1903). The subject of the bulletin is Spotted Fever (tick fever) of the Rocky Mountains. The disease has been known in the valley of the Bitter Root River in Western Montana for about 20 years and is sharply localised on the west bank of the river. It is also known to occur in Idaho, Nevada, Wyoming, and in a mild form in Oregon, but does not prevail south of 400 or north of 47°. It prevails at an average elevation of about 3000 to 4000 feet, exclu- sively in the spring and early summer, and among persons who follow occupations that cause exposure to the bites of ticks. To Wilson and Chowning belongs the credit of discovering an intracorpuscular parasite which is very probably the cause of the fever. Dr. Anderson saw the parasites under three forms : (1) the most common was a single ovoid body, refractile, and able to project pseudopodia ; (2) a larger form, larger at one end and showing a dark granular spot, also amoeboid ; and (3) a form arranged in pairs, distinctly pyriform, with the smaller ends approaching. On a study of the cases of tick fever it was always found that there was a history of tick bites about one week before the onset. The ticks which, a. e apparently necessary for the transmission of the disease belong to the genus dermacentor. The symptoms which follow the incubation of about seven days are for a few days chilly sensations, malaise, and nausea ; finally there is a distinct chill and the patient takes to bed. There are pains in the head and back ; soreness of the muscles and bones ; con- stipation ; tongue with heavy white coat, red edge and tip ; conjunctivas congested, becoming yellowish ; urine scanty, with albumin and a few casts ; slight bronchitis after a few days ; and bleeding of the nose, sometimes quite severe, is always present. Before the distinct chill there is little or no fever in the morning, with a slight rise of tem- perature in the afternoon. After the chill there is an abrupt rise and then the fever gradually increases in the evening, with a slight morning remission. The maximum is usually reached on from the eighth to the twelfth day. The pulse-rate appears out of all proportion to the tem- perature, usually running from 110 to 140. Red blood counts show a progressive decrease in red cells. The white blood corpuscles are increased in number, a most interesting feature being an increase of the mononuclears. The eruption appears usually on the third day, first on the wrists and ankles, then on the arms, legs. forehead, back, chest, and, last and least, on the abdomen. At first the spots are bright red ; they are macular and in size from that of a pin-point to that of a split pea. From about the sixth to the tenth day of the disease they fail to disappear on pressure and are distinctly petechial in character. When convalescence is advanced desquama- tion extends over the entire body. Of 121 cases which occurred in or near the Bitter Root Valley 84 patients died. Since the discovery of the parasite Dr. Wilson and Dr. Anderson suggested the use of quinine in large doses, preferably hypodermically. In five cases in which it was used recovery took place. Quinine bimuriate, one gramme, should be given every six hours hypodermically. The heart’s power should be supported with strychnine and whisky. The patient should be encouraged to drink large quantities of water to flush out the kidneys. For the fever warm sponge baths or packs are useful and refreshing. Milk, broths, lightly boiled eggs, and soft toast may be allowed. As soon as a person is bitten by a tick the insect should be removed and the place cauterised with 95 per cent. carbolic acid. By applying ammonia, turpentine, kerosene, or carbolised vaseline the tick can usually be detached without trouble. HOMES FOR EPILEPTIC PATIENTS IN POOR CIRCUMSTANCES.
