The radialist's religious fervor

• The MATRIX Trial proved that radial was superior to femoral in ACS patients due to reduction in complications with equal effectiveness.
• This large study suggests that the radial approach can be equally successful compared to the femoral approach in CTOs.
• Since so few radial CTO procedures were included, one wonders whether CTO operators with MATRIX‐like radial experience could have less complications than the femoral approach in these procedures.

     

Differences in Lip Support with and without Labial Flanges in a Maxillary Edentulous Population – Part 3: Unblinded and Discriminatory Subjective Analysis

Purpose

To study the subjective differences in direct lip support assessments and to determine if dentists and laypeople are able to discern and correctly identify direct changes in lip support between flange and flangeless dentures.

Materials and Methods

A random sample of 20 maxillary edentulous patients described in part 2 of the study was used for analysis. A total of 60 judges comprising 15 general dentists, 15 prosthodontists, and 30 laypeople, the majority of who were distinct from part 2 of the study, were recruited. All images used in this study were cropped at the infraorbital level and converted to black and white tone, to encourage the judges to focus on lip support. The judges were un‐blinded to the study objectives and told what to look for, and were asked to rate the lip support of each of the 80 images on a 100 mm visual analog scale (VAS). The judges then took a discriminatory sensory analysis test (triangle test) where they were required to correctly identify the image with a flangeless denture out of a set of 3 images. Both the VAS and triangle test ratings were conducted twice in a random order, and mean ratings were used for all analyses.

Results

The overall VAS ratings of lip support for images with flangeless dentures were slightly lower compared to images with labial flanges, and this difference was statistically significant (p < 0.0001). This was true for both profile and frontal images. However, the magnitude of these differences was too small (no greater than 5 mm on a 100‐mm scale) to be clinically significant or meaningful. The differences in VAS ratings were not significant between the judges. For the triangle test, judges overall correctly identified the flangeless denture image in 55% of frontal image sets and 60% of profile image sets. The difference in correct identification rate between frontal and profile images was statistically significant (p < 0.0001). For frontal and profile images, prosthodontists had the highest correct identification rate (61% and 69%), followed by general dentists (53% and 68%) and by laypeople (53% and 50%). The difference in correct identification rate was statistically significant between various judges (p = 0.012). For all judges, the likelihood of correctly identifying images with flangeless dentures was significantly greater than 1/3, which was the minimum chance for correct identification (p < 0.0001).

Conclusions

Removal of a labial flange in a maxillary denture resulted in slightly lower ratings of lip support compared to images with a labial flange, but the differences were clinically insignificant. When judges were forced to look for differences, flangeless dentures were detected more often in profile images. Prosthodontists detected the flangeless dentures more often than general dentists and laypeople.     

Metronidazole and amebiasis

Previous reports indicate that metronidazole is highly effective in the therapy of colonic amebiasis and in the treatment of hepatic amebic abscesses when combined with aspiration. A retrospective review of 15 cases of intestinal amebiasis and 12 patients with amebic liver abscesses treated with metronidazole alone is reported. Based on the literature and the clinical response of the patients reported herein, metronidazole is the initial drug of choice in the therapy of amebic colitis because of its ease of administration, efficacy, and low toxicity. In the treatment of hepatic amebic abscesses, metronidazole alone is adequate therapy for most cases, but occasionally there will be progression of the disease despite standard dosages of the drug.     

Amino acid absorption and incorporation after hypophysectomy

Uptake of the amino acidsl-glycine,l-leucine,dl-methionine, anddl-ornithine by the small bowel of the rat was enhanced during a 4 to 5 day period following hypophysectomy but was subsequently depressed. Synthesis of small-bowel protein was depressed soon after hypophysectomy. These early effects were independent of the reduced food intake by the hypophysectomized animals.     

Women and War

Most of today's 1.7 million women veterans obtain all or most of their medical care outside the VA health care system, where their veteran status is rarely recognized or acknowledged. Several aspects of women's military service have been associated with adverse psychologic and physical outcomes, and failure to assess women's veteran status, their deployment status, and military trauma history could delay identifying or treating such conditions. Yet few clinicians know of women's military history—or of military service's impact on women's subsequent health and well being. Because an individual's military service may be best understood within the historical context in which it occurred, we provide a focused historical overview of women's military contributions and their steady integration into the Armed Forces since the War for Independence. We then describe some of the medical and psychiatric conditions associated with military service.     

Dysphagia lusoria caused by persistent right aortic arch with aberrant left subclavian artery and diverticulum of kommerell

Sammary It requires a high index of suspicion to make the diagnosis of dysphagia lusoria. Clinically, these adults will present with symptoms of intermittent solid food dysphagia, and a mediastinal abnormality may be seen on chest x-ray. Noninvasive imaging of the chest with either computerized tomography or magnetic resonance scanning are excellent methods for evaluating the mediastinum for solid tumors or vascular anomalies that can cause extrinsic esophageal compression. Dysphagia lusoria caused by a persistence of the right embryologic aortic arch and diverticulum of Kommerell with an aberrant left subclavian artery may be satisfactorily managed by dietary modification when the symptoms are mild.The opinions and assertions contained herein are the private ones of the authors and are not to be construed as official policy or reflecting the views of the Army or the Department of Defense.
