Large irritation fibroma of hard palate: a case report of a rare clinical entity.

Fibromas are benign tumors of connective tissue common in the oral cavity but rare on hard palate. This paper reports on an asymptomatic, slowly growing mass on the hard palate of a 90-year-old lady, with a reported use of denture for two decades. The patient presented with a 2.2cm, smooth-surfaced, well-circumscribed nodule attached with a stalk to the palatal mucosa. After excision, the histopathological examination revealed a mass of fibrous connective tissue, covered by stratified squamous epithelium with focal low-medium grade hyperplasia and hyperkeratosis. These findings were consistent with irritation fibroma of hard palate, a rare entity, which should be considered as a possible diagnosis for tumors of the area by every physician.

Evidence of sympathetic innervation and α1-adrenergic receptors of the long head of the biceps brachii tendon.

BACKGROUND: The primary purpose of this study was to investigate the sympathetic innervation of the long head of the biceps brachii tendon LHB via immunohistochemical staining for protein S-100 and neuropeptide Y (NPY) in patients with complex proximal humerus fractures, in individuals with chronic biceps tendinosis in the setting of large rotator cuff tears (RC), and in cadaveric samples with no previously reported shoulder pathology. METHODS: We investigated the presence of sympathetic innervation and α1-adrenergic receptors of the long head of the biceps brachii tendon (LHB) in patients with complex proximal humerus fractures and individuals with chronic biceps tendinosis in the setting of large rotator cuff tears (RC). The correlation of morphological features with immunohistochemical evidence of neural element presence was also investigated. Forty-one LHB tendon specimens were examined. Seventeen were harvested from patients who underwent hemiarthroplasty for proximal humerus fractures, 14 were from individuals with biceps tendinosis in the context of a large RC tear, and ten were from cadaveric controls with no previous shoulder pathology. Histologic examination was performed using hematoxylin and eosin. Immunohistochemistry was used to detect the expression of the protein S-100, neuropeptide Y, and α1-adrenergic receptors, as well as to characterize the potential neural differentiation of tendon cells. RESULTS: A strong correlation between the expression of NPY/S-100, α1-adrenergic/S-100, and α1-adrenergic/NPY was found. The LHB tendon has sympathetic innervation and α1-adrenergic receptors in acute and chronic pathological conditions. CONCLUSION: Our results provide useful guidance on the management of tendinosis and the handling of the LHB in hemiarthroplasties for fractures.

Colorectal cancer screening awareness among physicians in Greece.

BACKGROUND: Data comparison between SEER and EUROCARE database provided evidence that colorectal cancer survival in USA is higher than in European countries. Since adjustment for stage at diagnosis markedly reduces the survival differences, a screening bias was hypothesized. Considering the important role of primary care in screening activities, the purpose of the study was to investigate the colorectal cancer screening awareness among Hellenic physicians. METHODS: 211 primary care physicians were surveyed by mean of a self-reported prescription-habits questionnaire. Both physicians' colorectal cancer screening behaviors and colorectal cancer screening recommendations during usual check-up visits were analyzed. RESULTS: Only 50% of physicians were found to recommend screening for colorectal cancer during usual check-up visits, and only 25% prescribed cost-effective procedures. The percentage of physicians recommending stool occult blood test and sigmoidoscopy was 24% and 4% respectively. Only 48% and 23% of physicians recognized a cancer screening value for stool occult blood test and sigmoidoscopy. Colorectal screening recommendations were statistically lower among physicians aged 30 or less (p = 0.012). No differences were found when gender, level and type of specialization were analyzed, even though specialists in general practice showed a trend for better prescription (p = 0.054). CONCLUSION: Contemporary recommendations for colorectal cancer screening are not followed by implementation in primary care setting. Education on presymptomatic control and screening practice monitoring are required if primary care is to make a major impact on colorectal cancer mortality.
