Acute suppurative thyroiditis secondary to piriform sinus fistula: a case report.

We present a typical case of acute suppurative thyroiditis (AST), associated with a piriform sinus fistula. We illustrate the case with an ultrasound picture of a hypoechogenic perithyroid mass and a CT scan using intravenous iodine contrast showing a perithyroid hypodense mass with peripheral enhancement, the mass also having intrathyroid involvement. When clinical and radiological findings suggest the presence of AST, it is necessary to rule out the presence of a piriform sinus fistula by means of a radiological study with barium contrast. Piriform sinus fistula is a rare abnormality derived from the branchial arch which is directly related to recurrent episodes of AST; surgical excision is hence, necessary to avoid such episodes.

Anatomical variation in the rudimentary horns of a unicornuate uterus: implications for laparoscopic surgery.

A case of laparoscopic excision of a rudimentary horn is presented. The anatomical features of this case are contrasted with others in the published literature. A 23 year old nulligravida presented with severe dysmenorrhoea and a pelvic mass. At laparoscopy a unicornuate uterus with a rudimentary horn was identified. The patient had stage III endometriosis. The rudimentary horn was attached to the unicornuate uterus by a band of tissue. The blood supply was identified within this band of tissue. The rudimentary horn was removed laparoscopically with no complications. There are two anatomical variations in the attachment of the rudimentary horn to the unicornuate uterus. Knowledge of both types is important to avoid complications such as bleeding and possible compromise of myometrial wall thickness.

A computer-controlled, continuously circulating, hot irrigating system for endometrial ablation.

OBJECTIVE: This study evaluated the efficacy of a computer-controlled thermal catheter system to ablate the endometrium by use of 5 to 15 ml of hot saline solution. STUDY DESIGN: Five in vivo sheep uteri and 32 freshly excised human uteri were studied by inserting a self-contained heater catheter equipped with thermocouples and circulating hot saline solution for 15 minutes within the uteri at various temperature settings ranging from 60 degrees C to 80 degrees C. The uteri were grossly examined and microscopically evaluated by hematoxylin and eosin and reduced nicotinamide adenine dinucleotide-diaphorase stains for degree of acute destruction, depth of thermal injury, and predicted viability. RESULTS: All 80 degrees C sheep treatments resulted in complete loss of viability at mucosal, submucosal, and myometrial levels. In human uteri temperatures > or = 80 degrees C produced grossly recognizable thermal damage to the endometrium. Full-thickness irreversible damage was seen in the endometrium. Loss of viability was also demonstrated 1 to 3 mm deep in the superficial myometrium. Intrauterine pressure was demonstrated to range from 20 to 40 mm Hg, with a mean of 26 mm Hg. No leakage of fluid from the oviducts was observed. CONCLUSION: The data presented here demonstrate that a simple technique coupled with a sophisticated monitoring control system could successfully ablate the endometrium without the vagaries associated with individual operator skill levels.

Fulminant infection with emphysematous changes in the biliary tract and air-filled liver abscesses.

Gas-producing infections are related to anaerobic bacteria and usually associated with immunosuppressive pathologies such as diabetes and have a fulminating course. We present the clinical course of a patient with diabetes whose infection progressed rapidly and ended in her dramatic death in a short period; surgical therapy was impossible, and the disease behaved similarly to type I emphysematous pyelonephritis.
