Several studies have highlighted the increase in physiological activity which occurs in pilots during flight and especially during takeoffs and landings. For example, it has been clearly demonstrated that pilots' heart rates increase during the landing approach to reach a peak at or just before touchdown. These changes have been attributed to workload and to psychological or emotional stress. This paper examines a number of test pilots' heart rate responses recorded during various flight trials involving different types of aircraft. Examples include ramp takeoffs in a VTOL fighter, automatic landings in fog, supersonic flight through monsoon rain, and a sortie in which the pilot developed acute appendicitis. It is concluded that heart rate responses in experienced pilots are influenced almost entirely by workload-related factors and not by emotional stressors, such as risk and anxiety. Because of the emotional overtones of the word "stress," it is suggested that the term workload should be used when referring to the reason for increased cardiovascular activity of pilots.

Twenty cases of ischemic bowel disease were analysed to determine the frequency and significance of fibrin thrombi in this condition. Fibrin thrombi were present in all 10 patients with occlusive ischemic bowel disease and in 7 of the 10 patients with nonocclusive ischemic bowel disease. In addition, fibrin thrombi were noted in a wide variety of specific and nonspecific inflammatory bowel diseases and in acute appendicitis. We conclude that fibrin thrombi are a nonspecific feature of tissue necrosis and that their mere presence in the bowel should not be regarded as an expression of disseminated intravascular coagulation.

The pharmocokynetics of a semisynthetic penicillin-ampicillin in acute appendicitis in children has been studied. Intramuscular and intravenous injections of 12,5 mg/kg and 25 mg/kg single doses of the antibiotic were administered. 50 children aged from 4 to 14 years were examined. Both ways of administration led to the creation of the ampicillin therapeutic concentration in the blood serum, but in case of intramuscular injection the circulation of the antibiotic in the blood was more prolonged. With the increase of the dose the antibiotic concentration in the blood and tissues of the abdominal cavity rises but without any significant prolongation of its circulation time in the blood.

An analysis of the medical records of 103 women with Crohn's disease points up the following observations. There is a slight increase in spontaneous abortions and a substantial degree of subfertility. The obstetric experience is the same as in the normal obstetric population and the effects of the disease on pregnancy and of pregnancy on the disease are minimal. Features seemingly unrelated to Crohn's disease and of a gynecologic nature may be present months before the onset of the main bowel inflammation. These features consist of abscesses, fistulas, ulcers, fissures, and infections involving not only the internal pelvic organs but also the vulvovagina, perineum, labia, rectovaginal septum, rectum, and anus. The onset of Crohn's disease may be acute and present the picture of an abdomen requiring surgical treatment. A tender, low abdominal, adnexal, or pelvic mass may incorrectly be diagnosed as acute appendicitis, pelvic inflammatory disease, or ovarian cyst, and lead to surgery. In 23 instances the diagnosis of Crohn's disease was established only after laparotomy. A total of 27 appendectomies were performed and none of these patients had acute appendicitis. Four pelvic abscesses developed after the appendectomies. To avoid the pitfalls of misdiagnosis and mismanagement, the nature of Crohn's disease should be understood and the gynecologic aspects of the disease recognized.

A rare disease that can mimic acute appendicitis is infarction of accessory spleen. It may occur in children and is difficult to diagnose preoperatively. Greater awareness of this entity may show not only that it is associated with other intraabdominal anomalies but also that it is more common in the tropics than elsewhere. Two cases are reported.

One percent (40 infants) of all the children treated for acute appendicitis at Our Lady's Hospital for Sick Children presented during the first 2 yr of life. Nineteen of the 40 children had an appendix mass at the time of the diagnosis. Conservative management of the appendix mass followed by delayed elective appendectomy is a safe and effective method of treatment.

A premature 12-day-old infant with ischemic infarction of the appendix due to hernial incarceration is presented. Literature review (1901-1975) of 106 cases of acute appendicitis in the first 30 days of life permitted tabulation of some clinical aspects in 94 cases. Overt manifestations mandating surgical intervention and isolation of the inflammatory process in the inguinoscrotal region are important factors responsible for the significantly better prognosis for neonatal hernial versus intraabdominal appendicitis.

The radiological findings in 93 children operated on for acute appendicitis were reviewed retrospectively; acute appendicitis was confirmed in 76 (81%). These children were compared with 40 children with abdominal pain, but without appendicitis. Pre-operative radiographs in the children with appendicitis showed a significantly higher incidence of scoliosis, properitoneal line displacement, caecal dilatation with air/fluid levels and terminal ileal dilatation with air/fluid levels. The incidence of radiologically demonstrable faecaliths was not statistically higher in the children suffering from acute appendicitis. In children under the age of 4 years, in whom the diagnosis of acute appendicitis is often difficult, the radiological signs are helpful.

34 children with congenital hydronephrosis, operated upon for erroneosly diagnosed acute appendicitis (17), malignant tumor (11), and ileus (8), were under observation. To prevent from unwarranted surgical interventions in dubious cases excretory urography and other x-ray and instrumental methods of examination must be used widely. After the removal of an unchanged vermiform process in children, suffering from abdominal pain, the examination of the urinary tract is indicated. Such patients should be under dispensary observation of a children's surgeon.
