Management of severe trauma to distal digital extremities.

Abstract: There are several types of injuries, lacerations and amputations of the terminal phalanx. The goal in repairing such an injury is a serviceable, non-tender, durable tip as near normal length as possible in as short a time as possible. No one type of repair will suffice for each injury. There are many excellent methods of repair which can be used, and the choice must balance the type of injury, the age and the occupation of the patient, the knowledge of the surgeon and his familiarity with these many procedures to get the best result in each injured terminal phalanx. Whatever method of repair is used, postoperative rest, immobilization and elevation are essential to good healing.

Vitamin therapy in the surgical patient

Abstract: Vitamin therapy is of considerable importance in the pre- and postoperative care of surgical patients. Those of particular surgical interest are vitamins k , certain component factors of vitamin b and vitamin c because they are specifically related to the problem of nutrition and to body functions essential to normal tissue repair after surgery. Certain aspects of the general subject of vitamin therapy have been considered.

Cardiac achalasia in childhood

Abstract: Cardiac achalasia is a disorder not unknown in the paediatric age-group and may occur even in the neonatal period. This disorder should, therefore, be considered in all cases presenting with persistent vomiting, as well as in those with chronic respiratory disease in whom more common causes have been excluded. It is almost universally accepted that the disorder results from a disturbed function of ganglion cells in the distal oesophagus, as the disease has been reproduced in laboratory animals by denervation of the distal oesophagus. The exact pathogenesis of this degenerative change is not well understood. However, in at least some of the cases congenital absence of the ganglion cells may be responsible for this functional disturbance. This is inferred from the fact that the disease may be found in association with Hirschsprung disease, in which there is a congenital absence of ganglion cells in the terminal colon. Moreover, the occurrence of the disease in the neonatal period itself favours a congenital lesion. Surgery was preferred to other forms of treatment in the paediatric age-group in view of the reported equivocal response to mechanical dilatation and pre-disposition of children to respiratory complications. The results of surgery were satisfactory.

Achalasia of the Esophagus: A Follow-Up Study of Patients Undergoing Esophagomyotomy

Abstract: Cardiospasm, or achalasia of the esophagus, is a disease characterized by a lack of coordinated peristaltic motility in the body of the esophagus and by failure of the lower esophageal sphincter to relax after deglutition. At the present stage of knowledge, treatment for this condition has been restricted to relief of the obstruction in the lower part of the esophagus, and it has been ineffective in restoring normal esophageal motility. Mechanical dilation of the cardia has been of considerable value in the relief of symptoms of this condition and is vastly superior to earlier surgical procedures. These procedures (such as those of Wendel, Heyrovsky, and Grondahl), which destroyed or bypassed the esophagogastric junction, almost universally resulted in severe reflux esophagitis, and they have been abandoned. The present-day surgical treatment of cardiospasm was initiated in 1913 by Heller 1 and subsequently was modified by Zaaijer, 2 in 1923. It is this
