Real Photographic Prints from Digital Images

BACKGROUND: Digital photography is emerging as a standard method of documenting preoperative, intraoperative, and postoperative results in the clinical setting. While hard copies of these electronic images can be quickly and easily generated on color laser or inkjet printers, there are times when it is necessary to generate a true photographic print of an image, either for insurance documentation or to meet the publication requirements of a peer-reviewed journal. Standard inkjet and laser printers are unable to generate true photographic prints. OBJECTIVE: To identify a rapid, cost-effective means of generating high-quality photographs of digital images. METHODS: We describe the use of on-line service bureaus with digital photographic printers to obtain high-quality photographic prints of patient images. RESULTS: From as little as 49 cents per print, a color or black-and-white print of a color image can be generated by an on-line service bureau to satisfy the need for a photographic quality hard copy. CONCLUSIONS: While color laser or inkjet printers allow physicians to generate their own hard copies of electronic patient images, photographic quality images are at times needed to satisfy requirements for insurance documentation or publication in peer-reviewed journals. Use of on-line service bureaus is the most cost-effective way that we have found to obtain high-quality photographic color or black-and-white prints from electronically stored patient images.

Digital videofluorography and esophageal achalasia: from diagnosis to follow-up

The aim of this retrospective study was to evaluate the use of digital videofluorography in the preoperative and postoperative management of esophageal achalasia surgical treatment. From 1990 to 2004, 25 patients with achalasia, diagnosed by digital videofluorography and confirmed by motility studies and endoscopy, underwent surgery. All patients underwent digital videofluorography at 1, 6 and 12 months in order to evaluate the completeness of the myotomy and the efficacy of the antireflux procedures. At postoperative videofluorography esophageal transit time was decreased in all patients (100%); esophageal motor activity was unchanged in 23 (92%), and modified in two patients (8%) with onset of peristaltic-like motor activity; 8 patients (35%) presented decreased preoperative dilatation; all patients had a WST negative for post-myotomy reflux. On the basis of our experience and the advantages of the procedure we suggest videofluorography as a first-approach diagnostic examination useful for surgical indications and postoperative follow-up in achalasic patients.

Distally Based Dorsal Digital Fasciocutaneous Flap for the Repair of Digital Terminal Amputation Defects

The preferred plastic surgery regimen for distal digital segment wounds remains unknown, although multiple options are available for the repair. The purpose of this investigation is to study its anatomic rationale and clinical outcomes, in addition to the role of dorsal digital veins in digital reconstruction. Patients (n  =  765) suffering from digital terminal segment traumatic wounds (823 digits) were identified and reviewed in a retrospective manner. The wounds were repaired using distally based dorsal digital fasciocutaneous flaps with venoneuroadipofascial pedicles. Skin flaps survived in 818 digits (99.4%), whereas 5 flaps (0.6%) became partially necrotic. Postoperative follow-up data were available from 521 patients involving 559 digits, for an average duration of 10 months (range, 4–36 months). The wider pedicled fascial flap (1.0–1.5 cm) was significantly associated with a decreased occurrence of blebs, whereas the first few patients with pedicled fascial flaps 0.5 to 1.0 cm wide exhibited more frequent occurrence of blebs and flap contractures. The flaps retracted in size within the first 2 to 3 months at the rate of 10% compared with the intraoperative outlined size. The skin flaps became mildly pigmented within the first postoperative month, and at 6 months the flaps turned brighter in color, almost approximating the color of the normal digits. At 12 months, both the texture and appearance of the flaps were acceptable. The donor sites healed without any scar contracture. The digital terminals appeared grossly normal with acceptable digital function. Without any neural reconstruction, skin flap sensation was rated as S2 to S3+, whereas with neural reconstruction the 2-point discrimination sensitivity measured 4 to 9 mm. The use of a distally based dorsal digital fasciocutaneous flap with venoneuroadipofascial pedicle was a simple, safe, and less invasive regimen for repairing digital terminal segment wounds.
