Pelvic actinomycosis presenting as a malignant pelvic mass: a case report

<p>Abstract</p> <p>Introduction</p> <p>Pelvic actinomycosis constitutes 3% of all human actinomycosis infections. It is usually insidious, and is often mistaken for other conditions such as diverticulitis, abscesses, inflammatory bowel disease and malignant tumors, presenting a diagnostic challenge pre-operatively; it is identified post-operatively in most cases. Here we present a case that presented as pelvic malignancy and was diagnosed as pelvic actinomycosis post-operatively.</p> <p>Case presentation</p> <p>A 48-year-old Caucasian Turkish woman presented to our clinic with a three-month history of abdominal pain, weight loss and difficulty in defecation. She had used an intra-uterine device for 16 years, however it had recently been removed. The rectosigmoidoscopy revealed narrowing of the lumen at 12 cm due to a mass lesion either in the wall or due to an extrinsic lesion that prevented the passage of the endoscope. On examination, there was no gynecological pathology. Magnetic resonance imaging showed a mass, measuring 5.5 × 4 cm attached to the rectum posterior to the uterus. The ureter on that side was dilated. Surgically there was a pelvic mass adhered to the rectum and uterine adnexes, measuring 10 × 12 cm. It originated from uterine adnexes, particularly ones from the left side and formed a conglomerated mass with the uterus and nearby organs; the left ureter was also dilated due to the pelvic mass. Because of concomitant tubal abscess formation and difficulty in dissection planes, total abdominal hysterectomy and bilateral salphingo-oophorectomy was performed (our patient was 48 years old and had completed her childbearing period). The cytology revealed inflammatory cells with aggregates of <it>Actinomyces</it>. Penicillin therapy was given for six months without any complication.</p> <p>Conclusions</p> <p>Pelvic actinomycosis should always be considered in patients with a pelvic mass especially in ones using intra-uterine devices, and who have a history of appendectomy, tonsillectomy or dental infection. Surgeons should be aware of this infection in order to avoid excessive surgical procedures.</p

Audit of an emergency biochemistry service.

AIM--To examine a model for the evaluation of appropriateness of testing in an emergency biochemistry laboratory. METHODS--A model was devised in which incoming emergency test requests were categorised as appropriate or inappropriate. Explicit criteria were used to define eight minor categories, which were chosen to reflect accurately current working practice within the hospital and laboratory. Five junior medical staff each undertook a prospective 24 hour assessment, during which time all incoming requests were monitored and categorised according to these criteria. Concordance between monitors was evaluated before and during assessments. RESULTS--Of 509 requests, 384 (75%) were appropriate and 125 (25%) were inappropriate according to the criteria used to define categories. Inappropriate requests fell into three main groups: preoperative samples (43.2% (54/125) of all inappropriate requests), missed routine samples (33.6% (42/125)) and accelerated (priority) analyses (16% (20/125)). Various other reasons accounted for the remaining 7.2% (9/125). CONCLUSION--This model may be used to obtain valid information about current clinical and laboratory practice. Strategies to reduce the number of inappropriate requests have been identified in order to reserve the emergency service for situations of true need
