Roentgenography of paranasal sinuses during treatment of nasal polyposis.

Seventeen patients had severe nasal polyposis. Local treatment with beclomethasone dipropionate caused marked reduction in the size of polyps and the nasal obstruction, and the effect continued throughout the treatment period. In all cases roentgenographic examination showed clouding of the nasal cavity and the paranasal sinuses, especially of the maxillary and ethmoidal sinuses. After three months of treatment, no change in the opacity of the sinuses was found. In spite of that, the symptomatic effect of the treatment was successful.

Comparative analysis of age prediction by markers of bone change in the hand assessed by roentgenography.

The major aim of this study was to develop an accurate method of age prediction for a wide range of ages based on the roentgenographic assessment of the hand bones. Such a method may be of particular interest in paleoanthropology and forensic medicine. The present paper provides the results of an analysis of individuals belonging to two ethnically different population samples: 1) Chuvasha (the Russian Federation), 293 males and 254 females, aged 18-91 and 18-86 years, respectively; and 2) Turkmenians (the Republic of Turkmenia), 257 males and 386 females, aged 18-82 and 17-83 years, respectively. The hands of study participants were roentgenographed with standard methodology. For each roentgenogram an equidistant osseographic score (OSS) including the descriptive criteria of bone age was estimated. In addition, an osteoarthritic and an osteoporotic score (OA and OP, respectively) were assigned to each individual. OA was a modification of the Kellgren/Lawrence scale, whereas the OP was locally developed. Results of the multiple logistic regression analysis clearly indicated that OSS is a strong predictor variable of an individual's age, with R reaching 0.93 in Chuvasha and 0.89 in Turkmenians (P < 0.001). The standard errors of estimate were approximately +/-5-7 years and compared favorably with most known methods of age assessment using bones. This study provides an efficient method of age prediction, with acceptable accuracy, and extends the upper limit of prediction to the age of 70 years. An additional finding of interest was the coexistence of OA and OP in the bones of the same hand. The observed correlation between these two conditions reached 0.8 (P < 0.001). Am. J. Hum.

Detection of metastatic malignant melanoma by chest roentgenography.

The latest premortem chest roentgenogram on 17 patients with known metastatic malignant melanoma was examined and the results were compared with the findings in the chest at autopsy. In nine of the 17, disease not visible on the roentgenogram was found at autopsy. Preliminary data would indicate that a significant number of these metastases could have been identified premortem by other radiographic modalities, e.g., tomography.

Correlative roentgenography and morphology of the longitudinal epiphyseal bracket.

Detailed examination of a complete chondro-osseous specimen from a patient with duplication of the first ray of the foot revealed the involved metatarsal had a trapezoid-shaped, diaphyseal-metaphyseal osseous unit that was longitudinally bracketed along the lateral side by a functioning physis, epiphysis, and secondary (epiphyseal) ossification center. The physis extended as an arc from the medial proximal side toward and along the lateral side and then back to the medial side distally. The medial side of the diaphysis had a normal periosteum. The longitudinal epiphyseal ossification bracket was a composite of initially separate proximal and distal secondary ossification centers that had progressively extended toward each other and finally coalesced along the laterally placed epiphyseal cartilage. We have termed this deformity the "longitudinal epiphyseal bracket" (LEB). The macroscopic and microscopic anatomy relevant to initial diagnosis and evaluation of sequential roentgenographic changes will be considered.
