"True" color surface anatomy: mapping the Visible Human to patient-specific CT data.

The mapping of "true" color and texture information into traditional medical imaging modality data can add considerable information and aid in diagnostics. One of the goals of this work has been to create CT color lookup tables for all visually well-defined structures in the Visible Human male cryosection data set which then can be used to color patient-specific CT data. The primary goal has been to develop a method for stripping textures from a volumetric data set for polygonal models and non-uniform rational B-spline (NURBS) models generated from a volumetric data set. It is believed that these methods can eventually be used to provide clinicians with 3D models with physiologically accurate color textures.

[Long-term results of epicondylitis humeri ulnaris ("golfer's elbow") after treatment analogous to Hohmann's incision of epicondylitis humeri radialis ("tennis elbow")].

With an average follow-up of 6.1 years the results of Hohmann's operation in treatment of humeri ulnaris epicondylitis in 23 cases are presented. For evaluation a numerical rating system with subjective and objective criteria was designed. The results were excellent in 43.5%, good in 26.1% and fair in 17.5% by subjective and excellent in 47.9%, good in 26.1% and fair in 13% by objective evaluation. Three cases had a poor result. The study reviews causes, clinical tests, conservative treatment and our operative method.

[Rupture of the pectoralis major muscle--case study and review of the literature].

Rupture of the pectoralis major muscle is a rare injury. In total 125 cases of complete and uncomplete ruptures are reported. This injury is the result of excessive muscle tension, a direct blow or a combination of both. In a case study the aetiology, diagnostic, treatment and functional outcome of complete muscle ruptures are shown. The reported results of 14 cases who underwent conservative and 51 cases with surgical treatment were classified and analysed. Conservative management is recommended for partial and proximal ruptures. Distal ruptures of the musculo-tendinous or tendinous insertion in active patients should be treated surgically to return previous muscle strength and contour.

Specimen adequacy of ThinPrep sample preparations in a direct-to-vial study.

OBJECTIVE: To assess specimen adequacy of the ThinPrep slide preparation method in routine use. STUDY DESIGN: Two studies, a feasibility study of 299 women and a clinical study of 499 women, were conducted. A broom-type collection device was used and rinsed directly into Pre-servCyt vials. Slides were prepared with the ThinPrep 2000 device, screened and classified according to the Bethesda System. The proportion of ThinPrep slides described as "Satisfactory But Limited By: No Endocervical Component (SBLB:No ECC)" was then compared to the proportion of SBLB: No ECC slides found on conventional smears in a previously conducted clinical trial of over 7,000 patients. RESULTS: For the feasibility study the proportion of ThinPrep slides described as SBLB: No ECC was 9.36% as compared to the clinical trial combined rate of 9.4% for conventional smears. For the clinical study, 4.96% of ThinPrep slides were SBLB:No ECC as compared to the 4.4% SBLB:No ECC rate for conventional smears from the same clinical trial. The proportions were statistically equivalent for both studies. CONCLUSION: It is expected that the rate of representing endocervical component will be maintained when the ThinPrep preparation method is used routinely in place of the conventional cytologic smear method.

Fine needle aspiration cytology of acrometastasis. A report of two cases.

We describe two cases of adenocarcinoma metastatic to the fingers diagnosed by fine needle aspiration (FNA). In one case pain in the finger lesion was the presenting symptom of bronchogenic carcinoma, and the cytologic examination led to discovery of the primary neoplasm. In the second case, FNA of the finger lesion helped document the presence of extensive osseous metastasis from a primary adenocarcinoma of the gastroesophageal junction. These cases illustrate the usefulness of FNA biopsy in distinguishing acrometastasis from other, more common, nonneoplastic, destructive lesions, which it can mimic clinically.
