background developing controlled hypercarbia is a known scheme of lowering the suprasellar part of the adenoma in order to assist the surgeon, which acts through raising the icp and therefore the csf pressure. objectives the purpose of this study is to compare the effect of introducing a lumbar drain with that of controlled hypercapnia on the quality of transsphenoidal pituitary tumor resection...

BACKGROUND New biological markers are needed for diagnosis of atypical pituitary adenoma. The study aimed to evaluate cathepsins B and L and inhibitor stefin A in relation to their aggressive progression. PATIENTS AND METHODS We evaluated 19 adenomas and 10 normal hypophyses. Adenomas were divided according to their histological features and according to their functional activity, e.g. hormon...

osteitis fibrosa cystica is the classic patognomonic form of skeletal disease in hyperparathyroidism that characterizes with decreased cortical bone thickness compared to increased cancellous bone. we present a case of 52-year old female patient with osteolysis of the left calf on radiographic images. the bone scan detected multiple focal pathological accumulations in the skull, left tibia, bot...

background: visfatin is an adipocytokine secreted by visceral adipose tissue. it has been shown that adipocytokines may contribute to the induction of carcinogens and progression of tumors. previously, we found a significant increase in the visfatin serum level in colorectal cancer patients. herein, we investigated if this cytokine increases in patients with colorectal adenoma as a precursor of...

introduction: the co-existence of pituitary adenoma and meningioma is extremely rare. it is even rarer in patients with no previous known risk factors for either tumour. here, we present a case of synchronous non-functioning pituitary adenoma with suprasellar and olfactory groove meningiomas in a patient without previous irradiation. methods: the tumours were diagnosed on mri in the 65-year-old...

Background & Aim: Pituitary adenomas are part of a dissimilar group of benign neoplasms. The development of endoscopic techniques for surgery of paranasal sinuses has increased the opportunity for an endoscopic approach with regard to the pituitary gland. Minimally invasive endoscopic pituitary surgery, in turn, permits a more thorough tumor resection and fewer associated surgical complications...

PURPOSE The UDP glucuronosyltransferase 1A6 (UGT1A6) and cytochrome P450 2C9 (CYP2C9) enzymes participate in the metabolism of nonsteroidal anti-inflammatory drugs, endogenous substances, and carcinogens. Functional polymorphisms of UGT1A6 (T181A and R184S) and CYP2C9 (R144C and I359L) have been reported to modify the protective effect of aspirin on colorectal adenoma risk. We aimed to further ...

Salivary gland tumors are among the pathologies in the head and neck that may be challenging in diagnosis and treatment. Most benign tumors occur in the parotid gland. Pleomorphic Adenoma is the most common type. Basal Cell Adenoma is a subtype of the Monomorphic Adenoma with rare occurrence. Proper diagnosis and clinical evaluation by the use of radiography can lead the physician to the best t...

discussion: the histopathological examination showed increased number of acini with preserved duct-acinar connection, consistent with nodular hyperplasia. the patient had used oral contraceptive pill for four years. introduction: tumors which originate from the bartholin’s glands (bgs) are very rare. many solid masses that arise from the bgs are carcinoma, though these benign solid lesions are ...
