Traumatic mesenteric arteriovenous fistula

Abstract A case of traumatic mesenteric arteriovenous fistula is presented. The clinical and angiographic findings are reviewed and discussed. Early recognition of the fistula is of utmost importance. Arteriography is essential for confirmation of the diagnosis and localisation of the lesion. Selective superior mesenteric arteriography is recommended in all suspected cases.

Vacuum contoured, liquid crystal, dynamic breast thermoangiography as an aid to mammography in the detection of breast cancer.

New thermographic equipment is introduced in the form of liquid crystals embedded in flexible, transparent, elastomeric sheaths which may be vacuum contoured to any breast. Dynamic thermoangiography, a new physiological method of performing thermography with these liquid crystal sheaths, is presented. Thermographic changes are recorded during active skin cooling and rewarming with liquid crystals in situ. The new system eliminates skin preparation previously required. Preliminary results appear to show good correlation with conventional telethermography. Vascular, as well as thermal pathology, is accentuated with rich, high contrast, thermographically calibrated colour patterns. The new system is relatively inexpensive, simple to operate, and may be suited to a programme for the detection of breast cancer.

A disposable kit for barium enemas.

The present methods of preparation and administration of the barium sulfate mixture in roentgen examination of the large bowel have certain disadvantages. The equipment, consisting of enema can, tubing, tip, and air-insufflation apparatus, must be carefully cleaned and sterilized. Sterilization, especially of the apparatus for air insufflation, is indeed difficult and is often neglected. Furthermore, measuring and mechanical mixing of the barium sulfate and water, whether done individually for each patient or carried out in a single, larger effort, consume additional time, with the possibility of variations in the consistency of the mixture unless great care is exercised. Settling of the mixture before and even during its administration must be guarded against by frequent stirring. The chances of spillage from the can at one time or another are real and seemingly unavoidable. Considerations such as these prompted one of us (P.H.M.) to devise a disposable, plastic enema kit. The bag measures 14 × 7.5 inche...
