Lipoma arborescens (diffuse articular lipomatosis)

Lipoma arborescens (LA) (diffuse articular lipomatosis, synovial lipomatosis, Hoffa disease) is a rare intra-articular lesion of unknown etiology. This article presents three patients who had LA, which was diagnosed in the knee in two patients and in the wrist of the third patient. Details of the clinical and histomorphological examination and treatment, in addition to a review of the literature, are discussed. The article concludes that in patients with a slow increase in painless swelling of the joints, unresolving articular pain with or without limited motion, or intermittent effusions following a minor trauma, LA should be considered in the differential diagnosis. It should be remembered that LA occurs in joints other than the knee, such as the elbow, shoulder, and wrist. Although recommended surgery involves arthrotomy and synovectomy, arthroscopic synovectomy may be a useful treatment modality, particularly in the larger joints as the recurrence rate is low.     

Giant fibrosarcoma arising in dermatofibrosarcoma protuberans on the scalp during pregnancy

BACKGROUND: Dermatofibrosarcoma protuberans (DFSP) is a low-grade malignant soft tissue tumor of subcutaneous tissues that has a propensity for local recurrence; however, it seldom metastasizes. Most lesions occur over the trunk or proximal extremities, and there is slight male preponderance. DFSP is rare on the head and neck. Less than 5% tumors are located on the scalp. OBJECTIVE: To describe a case of giant fibrosarcoma arising in DFSP on the scalp during pregnancy. METHOD: In our patient, the tumor was on scalp and measured 15 x 11 x 7 cm. The recurrent tumor that developed in the same region was measured 33 x 30 x 15 cm. Histopathologic examination of this mass revealed fibrosarcoma. The mass was excised from the subperiosteal plane with a 3-cm free margin. Because of the high possibility of recurrence, the defect site was reconstructed with a split-thickness skin graft. RESULTS: After 1 year of follow-up, no recurrence or metastasis was detected. CONCLUSION: We present a unique case in which the person has a giant fibrosarcoma on her scalp arising from DFSP with fibrosarcomatous change during pregnancy.     

The Hungarian translation of the "Dental Fear Survey" based on the Hungarian population

Authors translated the "Dental Fear Survey" (DFS) into Hungarian. 196 persons have been investigated and the DFS values have been compared to DAS, STAI-S, STAI-T values. Mean values were: DFS: 46.27; DAS: 12.24; STAI-S: 41.58; STAI-T: 42.68. Authors found all values higher in the case of women comparing to men. Positive correlation has been found between DAS and DFS, but STAI-S and STAI-T increased only moderately comparing to the DAS and DFS values.     

Free-Floating Tumor Thrombus in the Left Atrium Associated with Non-Small Cell Lung Cancer

Abstract   A free-floating tumor thrombus in the left atrium is an unusual metastasis of non-small cell lung cancer. Surgical resection of free-floating tumor thrombus prior to adjuvant therapy relieves cardiac symptoms such as exertional dyspnea, and prevents life-threatening complications including systemic embolization, mitral obstruction, or sudden death.

Grip strength measurement for frailty assessment in patients with vascular disease and associations with comorbidity,cardiac risk,and sarcopenia

Objective

Frailty is associated with adverse events, length of stay, and nonhome discharge after vascular surgery. Frailty measures based on walking-based tests may be impractical or invalid for patients with walking impairment from symptoms or sequelae of vascular disease. We hypothesized that grip strength is associated with frailty, comorbidity, and cardiac risk among patients with vascular disease.
