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

Abdominal muscular contractions may have a protective influence against the development of indirect inguinal hernia. A portion of the transversus abdominus muscles acts on the internal inguinal rings and produces a closure mechanism during voluntary abdominal muscular activity. It follows, therefore, that injury or inactivation of this mechanism may be an etiologic factor in the development of ind

The incidence of right inguinal hernia is significantly greater in patients who have undergone appendectomy than in the general population. The most likely cause of such hernias is injury to the segmental nerve supply to the inguinal musculature. The choice of incision at appendectomy may therefore be important, and the surgeon should avoid injury to the nerve branches and important structures in

The relationship of acute appendicitis occurring previous to cancer in colon and rectum was studied in the consecutive records of 561 patients, of 40 years of age and older, operated upon with an appendectomy because of acute appendicitis. Sixteen (2.9%) of these patients were readmitted within three years because of a carcinoma in colon or rectum. The incidence of carcinoma in the colon and rectu

The incidence of acute appendicitis and the total number of appendectomies performed in the adult population admitted to our medical center are both decreasing. The cause is not clear. Better nutrition and the wide-spread use of antibiotics are two possible factors which come to mind, but we know of no scientific evidence that these are responsible. There has been a slight decrease in the mean die

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.

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

The study described was designed to evaluate the role of auscultation and registration of bowel sounds in the diagnosis of acute appendicitis. In 37 patients with suspected acute appendicitis undergoing appendicectomy the bowel sounds were registered twice pre-operatively and once on the postoperative day. The results show that single registration of bowel sounds is rarely diagnostic, but repeated

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

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

In an experimental model using the rat, the role of invagination and double invagination for efficient closure of the caecum was studied. A standardized opening of the tip of the caecum was closed in three different ways, thus placing the animals in three groups. I: Closed with simple ligation. II: Closed with simple ligation and a purse-string suture invagination. III: Closed with simple ligation

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

The purpose of this study was to determine the usefulness of auscultation of bowel sounds in evaluating patients with total and subtotal small intestinal obstruction and immediately after operation. The study was based on ten healthy volunteers, seven patients with documented mechanical obstruction, one patient with chronic subtotal mechanical obstruction and twelve patients undergoing an emergenc

The purpose of this study was to compare the suture of a microvascular anastomosis with and without the aid of sodium hyaluronate. The divided femoral arteries of ten Sprague‐Dawley rats were sutured using sodium hyaluronate on one side. Operating time, bleeding, and patency rates were studied and compared. No significant differences were found in the measured parameters. However, the clinical imp

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

A simple and reproducible model for the experimental study of the normally functioning human appendix is described. The appendix removed from a human is transplanted into a nude mouse and is kept vital for at least 4 hours. This model is an improvement on previous models. It corresponds well with the working of the normal human appendix as regards tissue type and characteristics. Results are easil

In an experimental model using the human appendix transplanted into the Rowett rat, the role of obstruction in the pathogenesis of acute appendicitis was studied. Nine animals were anaesthetized and underwent laparotomy. Normal human appendices, removed during routine surgery, were transplanted into the rats. The appendices were obstructed by a balloon catheter introduced through the open end. Pre
