[Clinic and pathogenesis of Morton's disease (author's transl)].

From experience with 58 own cases the authors found that Morton's metatarsalgia due to a sclerosing neuroma of the plantar digital nerve is very often not recognised for many years. As this painfull affection easily can be cured, the clinical symptoms and histological findings, the diagnostic steps and treatment are described and the etiology discussed. For the excision of the plantar digital neuroma, situated generally between 3rd and 4th metatarsal head, the dorsal web-splitting approach is preferred because of better scars and immediate weigt-bearing. The operation is performed on outdoor patients. There were no complications. The results of 35 operations two or more years back show immediate and complete relief of pain in 31 cases and significant but incomplete relief in 4 cases.

[Surgical interventions on the vertebral bodies of the thoracic spine (author's transl)].

27 operations on the vertebral bodies of the thoracic spine are reported. Indications for operation included markedly progressive infantile and juvenile scoliosis, correction of severe kyphoses in congenital malformation, fractures, Scheuermann's disease and post-laminectomy as well as tuberculous spondylitis and tumors. The two uppermost thoracic vertebrae can be reached by the method of Southwick and Robinson, the two lowest vertebrae from an extraperitoreal-subdiaphragm approach. Thoracotomy was chosen for the remaining thoracic vertebrae. If the staff and material are available, operations on the thoracic vertebrae can be regarded as relatively safe and, in many cases, are the only possibility for obtaining a satisfactory or good result. In spite of this, strict indications must be observed. Severe complications (death, paraplegia etc.) did not occur in any of the patients.

[Starvation and surgical intervention].

The metabolic processes under conditions of stress and starvation are not identical. Moreover, they have to be differentiated, as far as carbohydrate-, fat- and amino-acid-metabolism are concerned, because both situations are not compatible. It is therefore required, to avoid any kind of starvation and particularly to substitute for adequate substrates during the pre- and postoperative period.

[Preoperative infusion therapy in childhood. I. Initial conditions and principles].

Infusion therapy for purposes of surgery differs significantly from the infusion requirements for "conservative" purposes, in adults as well as in infants and children. The preoperative situation of infants and children undergoing usual surgical procedures is particularly characterized by 1. the physiological conditions of the water-, electrolyte- and acid-base-balances; 2. the effects of the preoperative food-and fluid-restrictions; 3. the intraoperative fluid- and volumen-losses; 4. the combination between 1--3 and the postoperative food- and fluid-restriction and the postoperative metabolic conditions respectively. The problems, summarized under 1--4, have been discussed within this article. Further two papers will deal with studies on the use of "basic solutions" for the substitution of fluid- and electrolyte losses in pediatric surgery.

[Perioperative infusion therapy during childhood. II. Balance studies on pre-, intra- and postoperative infusion of basic solutions].

For a period of 63 hours totally, 4 different infusion solutions were administered to infants and children of 3 age groups (I = 10th day to the 6th month of age, II = 6th month to the 3rd year of age and III = above 3 years of age) during the pre-, intra- and postoperative period. The serum sodium, potassium-, chloride-, phosphate- and blood urea concentrations remained completely unchanged as well as the acid base parameters. Even between the age groups, no significant differences could be observed, as far as the above mentioned criteria are concerned. But the blood glucose concentrations increased within all age group in the immediate postoperative phase. The potassium concentrations in the urine decreased throughout in age group I. From these results, one can conclude, that these specific infusion solutions for paediatric surgical procedures with exception of solution I contained the most important electrolytes adaequately and that the amounts of fluids, which were given can be considered as sufficient. Nevertheless, the question remains, whether these different types of infusion therapy can be simplified by using more standardized solutions. This problem was subject to more sophisticated studies, which will be reported in the 3rd part of this publication, to be published at a later date.

[Acrodermatitis enteropathica in childhood (author's transl)].

A five months old infant is described with acrodermatitis enteropathica. The aetiology, pathogenesis and the clinical course of the disease is reported. It will be discussed the side effects of the oxychinolin therapy, the advantages and benefits of the substitution with zinc.

[Changes of the blood gases following the application of naloxon (author's transl)].

74 patients, undergoing gynaecological operations under neuroleptanesthesia were subdivided into 4 groups, each receiving Naloxone in different doses postoperatively. For a longer period of time tidal volume, respiratory rate, minute ventilation, blood gas volues and pain index were recorded. From the results one can conclude that 0.1-0.2 mg Naloxone i.v. seems to be the most effective dose to reverse opiate-induced respiratory depression. The initial i.v. dose should be followed by an i.m. dose of 0.2 mg, if required.

[Apgar status, blood gases and acid base balance of neonates after caesarean sections, using either thiopentone or ketamine for induction of anaesthesia (author's transl)].

Apgar status and acid base balance of 206 neonates, delivered by caesarean section under general anaesthesia, were investigated in order to compare the possible effects of either thiopentone- or ketamine-induction on the postpartum adaption. Several other criteria were recorded also, for instance, a possible neonatal asphyxia, the induction-delivery-interval, the maternal age, the administration of other than anaesthetic drugs etc. There were not correlations between the Apgar status and the induction-delivery interval in either groups. The number of neonates within the 3 Apgar-classes, and the asphyxiated neonates, were equally distributed in the thiopentone- and ketamine-groups. There was no correlation between maternal ages and either the thiopentone- or ketamin-babies, but a marked correlation with the number of depressed newborns. Those neonates, who were suspected to be hypoxic before anaesthesia showed a more depressed post-partum respiration after thiopentone- than after ketamine-induction. On the other hand it seems to be that neonatal respiration and total Apgar status was more depressed if the "ketamin mothers" were treated with sedatives, hypnotics and/or analgesics before caesarean section. The blood gas values and the acid base parameters did not show a statistically significant difference between the pH of the thiopentone- and the ketamine-neonates. These differences can be explained as the combination of the nonsignificant changes in PCO2 and standard-bicarbonate values. As far as can be judged from the above mentioned criteria it may be deduced that ketamine or thiopentone can equally well be used for inducation of anaesthesia for caesarean section.
