RESUMO
The role that physical attractiveness and fluctuating asymmetry (FA), a measure of developmental instability, play in self-perception and peer associations were explored in a well-studied cohort of Jamaican children using a novel research paradigm where subjects were already known to each other for extensive periods of time. The results showed that how attractive a child was perceived by others was significantly positively correlated with self-ratings of attractiveness. Contrary to findings from WEIRD (Western, Educated, Industrialized, Rich, Democratic) samples, the study found a reversal in the sex differences in self-perceived attractiveness and self-esteem, where Jamaican females rate themselves more attractive and report higher self-esteem than do males. Attractiveness also predicts overall popularity, as measured by desirability as a friend and the percentage of peers who choose an individual as a friend. Attractive individuals of both sexes were chosen more often as 'friends'. A significant correlation was also found between an individual's FA and the average FA of those chosen as friends. However, the effect was primarily due to preferences by males for female friends possessing similar levels of FA, which could be an effective strategy in reducing future mating effort.

Surgical resection in oral cancer patients can result in altered speech, swallowing, and patient perception of quality of life (QOL). Oral surgery can result in reduced lingual range of motion (ROM). However, few studies have quantified the degree of lingual restriction after surgery. This pilot study describes a new measurement system to define tongue ROM in surgically treated tongue cancer patients. This measurement system was validated by comparing results in these treated surgical patients versus healthy individuals. This scale was further validated by correlating ROM with performance status, oral outcomes, and patient-rated QOL. Thirty-six patients who underwent oral tongue surgery and 31 healthy individuals were included. Tongue ROM was assessed using a novel ROM assessment system. This novel system was examined in these patients versus healthy subjects. This measurement tool was further validated by correlating tongue ROM in treated patients with performance status, oral outcomes, and patient-rated QOL. Tongue ROM was found to be significantly lower in the surgically treated patients than in the healthy individuals (p = 0.0001). Tongue ROM correlated with performance status, oral outcomes, and all QOL measures. This new tongue ROM measurement system defined tongue deficits in surgically treated oral cancer patients. This tool was validated by comparing results to those in healthy individuals, as well as by correlating tongue ROM to performance status, oral outcomes, and QOL. This measurement tool can be used to define baseline and postsurgery tongue ROM in oral cancer patients, as well as track change over time with recovery and therapy. Future studies should examine use of this measurement tool with other populations demonstrating tongue deficits.

OBJECTIVE: To study MRI and positron emission tomography (PET)/CT imaging of osteoradionecrosis (ORN) of the subaxial cervical spine, a serious long-term complication of radiation therapy (RT) for head and neck cancers that can lead to pain, vertebral instability, myelopathy and cord compression. METHODS: This is a single-institution retrospective review of patients diagnosed and treated for ORN of the subaxial cervical spine following surgery and radiation for head and neck cancer. RESULTS: We report PET/CT imaging and MRI for four patients, each with extensive treatment for recurrent head and neck cancer. Osteomyelitis (OM) and discitis are the end-stage manifestations of ORN of the subaxial spine. CONCLUSION: ORN of the subaxial spine has variable imaging appearance and needs to be differentiated from recurrent or metastatic disease. Surgical violation of the posterior pharyngeal wall on top of the compromised vasculature in patients treated heavily with RT may pre-dispose the subaxial cervical vertebrae to ORN, with possible resultant OM and discitis. MRI and PET/CT imaging are complimentary in this setting. PET/CT images may be misinterpreted in view of the history of head and neck cancer. MRI should be utilized for definitive diagnosis of OM and discitis in view of its imaging specificity. ADVANCES IN KNOWLEDGE: We identify the end-stage manifestation of ORN in the sub-axial spine on PET/CT and MRI to facilitate its correct diagnosis.

The direct costs of medical care for cancer are examined at Kaiser Permanente (KP) in Northern California. Use data from July 1987 through June 1991 were obtained from KP automated files for all 21,977 KP patients in the Bay Area SEER registry with cancer at one of seven cancer sites. Medical charts were reviewed for a stratified sample of 886 patients. Costs were estimated for initial, continuing, and terminal care, and for all person time within 15 years of diagnosis, by stage at diagnosis. From diagnosis until death or 15 years, long-term costs attributable to cancer were as follows: breast, $35,000; colon, $42,000; rectum, $51,000; lung, $33,000; ovarian, $64,000; prostate, $29,000; and Non-Hodgkin's Lymphoma (NHL), $48,000. The utilization and cost results reported here may be useful in assessing the cost-effectiveness of cancer prevention and control programs, in adjusting capitation rates and budgets, and in estimating the aggregate medical care costs attributable to cancer.

OBJECTIVE: Scapular free flap harvesting for oral cavity cancer reconstruction is an increasingly used and versatile option. We aim to describe the appearance of the scapula harvest site on chest radiograph and CT. METHODS: We retrospectively reviewed a surgical database of 82 patients who underwent scapular osteocutaneous flap harvesting for oral cavity cancer reconstruction and had imaging performed at our institution. We searched the picture archiving and communications system for all associated imaging. RESULTS: Characteristic radiographic appearance in the immediate post-operative period as well as in the remote post-operative period is described, including an upside-down V-shaped paraglenoid notch, rectangular (or triangular) lateral border defects and a sharply pointed inferior scapular body. Additionally, common CT appearances are discussed, including an abrupt gleno-scapular interval, an absent axillary rim bulge and a Z-shaped scapula. CONCLUSION: The altered appearance of the scapular defect following surgical harvest is easily recognised. Although the description of this defect may not alter management and may reasonably be omitted, a radiologist's comfort with these appearances may potentially enhance the understanding of patient management and recognition of superimposed complications, such as infection. ADVANCES IN KNOWLEDGE: Scapular osteocutaneous free flap reconstruction is an increasingly used technique after oral cavity surgery. Very few radiologists reported in our review the surgical scapular defects, and there is apparent ignorance of their appearance. We described characteristic radiographic and CT signs of scapular free flap harvesting to increase radiologists' familiarity with these defects, which may provide clinical information and possibly contribute to detection of complications.

Osteoradionecrosis (ORN) of the mandible is a severe complication of radiation therapy for head and neck cancer. In this case series, the authors analyzed their treatment and quality of life outcomes over the past 6 years. A retrospective chart review of 42 patients treated surgically for advanced ORN was conducted. A telephone survey was conducted and quality of life (QOL) questionnaires were completed in a subset of patients. 30 patients responded to the telephone survey assessing QOL for speech, swallowing and overall functioning correlated with oral nutrition and performance status. Surgery for ORN can result in an improved QOL. Functional outcomes of oral intake, speech intelligibility, and eating in public correlated with patient rated QOL measures. A lack of improvement in QOL, despite the restoration of an intact mandible, relates to the persistent effects of chemoradiotherapy.
