Some factors affecting perforation in acute appendicitis

When acute appendicitis progresses to perforation, the consequences often lead to prolonged and difficult convalescence or even to death. It was of interest therefore to study a sample of patients with acute appendicitis and to investigate what factors appear to affect perforation in acute appendicitis. A series is presented of 248 patients with acute appendicitis. Seventy-seven of these were foun

Obstruction of the appendix lumen in relation to pathogenesis of acute appendicitis

The role of obstruction in the pathogenesis of acute appendicitis was studied by measuring the pressure in the appendix peroperatively in 33 patients undergoing appendectomy because of suspected acute appendicitis. The technique involved insertion of a fine needle via the apex into the lumen of the appendix and measurement of the hydrostatic pressure required to inject a saline solution. In all si

Relationship between the removal of the nonacute appendix and the menstrual cycle.

The significantly higher incidence of removal of a normal appendix in females in the second, third and fourth decades of life for suspected acute appendicitis lead to a study of the frequency of appendicectomy and the peroperative findings at the time of surgery in patients in different phases of the menstrual cycle. The results showed that the frequency of acute appendicitis in the luteal phase w

Varying frequency of acute appendicitis in different phases of the menstrual cycle

From the results of this study, it can be concluded that a difference is noted in the frequency of acute appendicitis and the number of appendectomies performed in different phases of the menstrual cycle. Therefore, the female sex hormones might play an important role in the cause of acute appendicitis. This is further supported by the lower sex specific incidence of acute appendicitis for women i

Ultrasonic Diagnosis of Testicular Torsion

An ultrasonic technique to avoid errors in the diagnoses of acute testicular torsion is described. The presence or absence of intratesticular arterial pulsation was recorded and analysed. The technique may reduce diagnostic failures and the number of scrotal explorations of nontorquered testis.

Treatment of malignant melanoma with dacarbazin (DTIC‐DOME) with special reference to urinary excretion of 5‐S‐cysteinyldopa

Seventeen patients were given DTIC, 200 mg/m2/day in five‐day courses every four to six weeks. In four patients (stage II) treated on an adjuvant basis, tumor recurrence has been verified in three. Four of the palliatively treated patients were also given DTIC by regional intra‐arterial infusion with minimal positive tumor effect and minimal toxicity. 5‐S‐cysteinyldopa excretion in urine was check

Acute appendicitis related to faecal stasis

The objectives of the study presented here were to evaluate the role of faecal stasis in the development of acute appendicitis. Inquiries about bowel habits were made of 188 patients admitted to this Department of Surgery with a clinical diagnosis of acute appendicitis, and of 188 healthy volunteers without known gastrointestinal disease, matched for age and sex. The results show that the number o

The level of copper, zinc and certain free amino acids in the plasma of patients with acute appendicitis

Many forms of inflammatory conditions are associated with alterations in physiology, metabolism and concentrations of trace elements such as copper, magnesium, zinc and calcium and of amino acid patterns and C-Reactive protein levels in plasma (1). Decreased levels of zinc and a reciprocal increase of copper in plasma has been seen in many human diseases (2). Nothing concrete is documented concern

Effect of loperamide on faecal control after rectoplasty for high imperforate anus

The effect of loperamide on faecal control after Stephens rectoplasty for high imperforate anus was studied in eight patients more than 8 years after surgery. Clinical assessment and anorectal manometry were performed before and after administration of loperamide for 6 to 8 weeks. Decreased faecal soiling was noted in seven of the eight cases. Obstipation forced two patients to stop the medication

Thyroid cancer incidence in relation to volcanic activity

Environmental or genetic factors are sought to explain the high incidence of thyroid cancer in Iceland. At present, it is impossible to cite any environmental factor, particularly one related to the volcanic activity in the country, which could explain the high incidence of thyroid cancer in Iceland. However, the thyroid gland in Icelanders is very small due to the high intake of iodine from seafo

Understanding GaAs Nanowire Growth in the Ag-Au Seed Materials System

The integration of III-V semiconductors with Si in device fabrication is facilitated by the use of nanoscale structures such as nanowires. Nanowires are predominantly grown using Au seed particles; however, the seed material is known to affect the nanowire growth and properties. Here we present growth of GaAs nanowires using three different seed particle materials: Au, Ag, and a AgAu alloy. By com

Effect of material parameter variability on vibroacoustic response in wood floors

The use of wood as construction material in multi-story buildings increased in Europe during the last decades. Wood buildings are more sensitive to dynamic loading compared to conventional concrete buildings, especially in terms of vibroacoustic comfort. Furthermore, it is more difficult to predict the accurate response due to dynamic loading for wood buildings. This is due to factors such as a co

Innovations in public diplomacy and nation brands : Inside the house of Sweden

This article investigates innovations in public diplomacy and nation brands through the example of Sweden's Embassy in Washington, DC, the House of Sweden (HoS). The analysis explores the styles of communication and public outreach made possible by the interaction between its architectural design, brand values and public diplomacy applications. Aimed at practitioners and scholars with an interest

Towards Prestige Mobility? : Diplomatic Prestige and Digital Diplomacy

This article responds to previous efforts to calculate diplomatic prestige while adapting these methodologies to the exigencies of digital diplomacy. In particular, we are interested in how digital diplomacy provides opportunities for diplomatic actors lacking in material resources to overcome prestige deficits. We adapt approaches used in earlier studies to calculate the material and ideational c

Haematopoietic stem cells retain long-term repopulating activity and multipotency in the absence of stem-cell leukaemia SCL/tal-1 gene

The production of blood cells is sustained throughout the lifetime of an individual by haematopoietic stem cells (HSCs). Specification of HSCs from mesoderm during embryonic development requires the stem cell leukaemia SCL/tal-1 gene product. Forced expression of SCL/tal-1 strongly induces blood formation in embryos, indicating that this gene has a dominant role in commitment to haematopoiesis. In
