Limb Salvage Surgery in a Voluminous Malignant Quadriceps Tumor.

It is uncommon for soft tissue sarcomas to develop after adenocarcinoma of the rectum. In a treated rectal adenocarcinoma patient, we encountered a huge malignant quadriceps tumor as leiomyosarcoma and salvaged the limb. A 49-year-old male known case of treated moderately differentiated adenocarcinoma of the rectum presented in the Orthopedic Clinic with a new swelling in his left thigh. MRI of the left lower limb was obtained, and it demonstrated a large 15.8 x 13.2 x 30 cm well-defined mixed solid cystic lesion in the anterolateral aspect of the left mid-thigh without the involvement of adjacent bony cortex. Limb salvage surgery with wide local excision of the tumor was done. The patient was ambulated full weight from the very next day with a Musculoskeletal Tumor Society Score (MSTS) score of 20. Despite the massive size of the tumor, limb salvage was attempted successfully and achieved good functional status.

Knowledge, Attitudes, and Practices Pertaining to Lung Cancer Screening Among Primary Care Physicians in a Public Urban Health Network.

INTRODUCTION: Lung cancer screening (LCS) with annual low-dose computed tomography in high-risk groups decreases the mortality related to lung cancer. Its implementation rate has been low, and knowledge relating to LCS has not been assessed in providers treating underserved populations. MATERIALS AND METHODS: An institutional review board-approved anonymous survey was sent to primary care physicians of the Cook County Health system, a safety-net healthcare system. The survey assessed the knowledge pertaining to LCS guidelines, providers' experience with LCS, and their recommendations for quality improvement using 24 questions. The predictors of LCS within the previous 6 months were identified using logistic regression analysis. RESULTS: Of the 152 survey responses, 43% were from nontrainees with diverse training backgrounds. Adequate knowledge of LCS was demonstrated by 72% of the respondents, and pretest counseling was the domain most often answered incorrectly in the questionnaire. LCS had been ordered in the previous 6 months by 57% of the respondents. However, 88% estimated that they had screened < 50% of eligible patients. Higher patient volume, more experience, and family medicine training predicted for ordering LCS in the previous 6 months. In addition, 82.2% indicated that prompts in the electronic medical records would increase LCS, and 78.3% reported that receiving statistics about their LCS practice would increase LCS performance. CONCLUSIONS: Primary care physicians in the hospital healthcare system had reasonable knowledge of LCS, but the implementation rate was low. We have identified areas for improvement relating to LCS implementation.

Effect of animal age, postmortem chilling rate, and aging time on meat quality attributes of water buffalo and humped cattle bulls.

The study was aimed to investigate the influence of animal age, post-slaughter chilling rate, and aging time on meat quality of M. longissimus dorsi (LD) of water buffalo (Bubalus bubalis) and humped cattle (Bos taurus indicus) bulls. After slaughtering, one side of carcasses was subjected to rapid chilling (RC) (0 ± 2°C) and other side was hanged in controlled room temperature (25 ± 2°C) for 3 hr, then allowed to the chiller (0 ± 2°C). The meat quality traits were analyzed at 1, 7, and 14 days of storage. It was noted that rapidly chilled carcasses from the younger animals of both species missed the ideal pH/temperature window, which affects the toughness of the meat. Buffalo meat presented higher shear force, color L* values, and lower b* value as compared to the cattle meat. Moreover, meat shear force values decreased while all color coordinates and cooking loss values increased with lengthening the storage time in both age groups of cattle and buffalo. In conclusion, the tenderness of cattle meat was superior to that of buffalo and RC adversely affect the shear force values of young cattle and both age groups of buffalo bulls.

Brain Metastasis in a Young Patient with Uterine Carcinosarcoma.

Uterine carcinosarcoma occurs almost exclusively in post-menopausal women and often carries high rates of disease recurrence and mortality. Central nervous system involvement is extremely rare with less than 10 reported cases in the literature. Here we present a young pre-menopausal patient with metastatic malignant mixed Mullerian tumor who developed cerebral metastasis while on systemic chemotherapy.
