Normal and pathological bowel sound patterns.

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

Sodium hyaluronate as an aid in microvascular surgery

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

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

Experimental model for the study of the human appendix

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

Etiological factors in acute appendicitis, an experimental study using the human appendix transplant

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

Testicular torsion in children - Bilateral or unilateral operation

Between 1969 and 1984 65 children were operated on for testicular torsion. A follow-up study of 63 patients who underwent surgery for unilateral testicular torsion with fixation only on the affected side showed that no torsion occurred on the opposite nonfixated side and there was no retorsion during an observation period of an average of more than seven years. From our calculated risk for contral

Bacteriuria in appendicitis

The value of bacteriologic findings in patients with acute appendicitis was studied. Routine urinary culture specimens were taken preoperatively from 194 children (mean age 11±3 years) undergoing emergency appendectomy. Bacteria were found in culture specimens of urine from 26 of 156 patients with acute appendicitis. The bacteriuria was correlated to the position of the appendix, the duration of d

The value of physiotherapy for faecal continence after correction of high anal atresia. A clinical and electromyographic study

A follow-up study of 12 patients who had undergone Stephens rectoplasty for high imperforate anus is presented. Clinical assessment and anal electromyography were performed more than 7 years after surgery, both before and after a year's physiotherapeutic training of the perianal musculature. Electromyography showed correlation between faecal continence and tonus of the anal sphincter, the anocutan

Neuropeptides in the human appendix - Distribution and motor effects

At present our knowledge of enteric peptide-containing neurons in man is limited. In this study we have used human appendices removed at surgery to examine the peptidergic innervation by immunocytochemistry, immunochemistry, and pharmacological in vitro experiments. Immunocytochemistry revealed a variety of peptide-containing nerve fiber populations in the human appendix. VIP/PHI-, VIP/PHI/NPY-, S

Computed tomography of ano-rectal anomalies : Correlation between radiologic findings and clinical evaluation of faecal incontinence

Computed tomography (CT) was performed in 9 patients with faecal incontinence more than 8 years after rectoplasty for high imperforate anus. The radiologic findings were correlated with the clinical evaluation of faecal incontinence. No statistically significant correlation was found between function and anatomic findings as demonstrated by CT. Thus, although CT demonstrates the post-operative ana

Computed Tomography and Magnetic Resonance Tomography Findings in Children Operated for Anal Atresia

Computerised tomography and magnetic resonance tomography were performed in nine faecally incontinent patients more than eight years after rectoplasty for high imperforate anus. No statistically significant correlation was found between function, i. e. degree of faecal incontinence, and anatomical findings. Thus, in spite of a detailed demonstration of the post-operative anatomy, the information d

Elective Testicular Biopsy at the End of Maintenance Treatment for Acute Lymphoblastic Leukemia. A Prospective Study

Open testicular wedge biopsy has electively been performed prior to completion of maintenance therapy for acute lymphoblastic leukemia. 25 boys during 6 years were included in this prospective study. Three boys developed testicular enlargement while on maintenance therapy and biopsies confirmed testicular leukemia. The remaining 22 boys were biopsied at termination of maintenance therapy. Occult t

The Social Capability Index and Income Convergence

Domestic social capabilities are a set of national characteristics for understanding why some countries grow faster than others. Yet there is no clear agreement on the main characteristics of these capabilities and therefore they have been neglected in the income convergence debate. The paper presents an index for revisiting the role of social capabilities in this debate. A relatively socially adv

Political battlefields : How within-firm goal conflict influences between-firm collaboration

In this paper, we inductively explore how within-firm goal conflict influences inter-firm collaboration over time. Based on our findings, we challenge current theorizing on collaborative dynamics in inter-organizational relationships, positioning firms as polilithic entities, where within-firm goal conflict can spur complex and unexpected between-firm collaborative processes and outcomes.

Developing a tool for self-assessment of IT process maturity : A design science research initiative

Today's IT organizations must ensure that IT services are aligned to business needs and actively support ongoing business processes. This means that internal IT service management processes are under constant improvement. However, to be able to know if the IT service provision develops in the right direction, there is a need to perform some kind of self-assessment of IT process maturity. In this p
