this case report describes a 59-year-old woman with a giant basal cell carcinoma on the face neglected for 11 years. surgical resection of the lesion resulted in a 13 × 11 cm defect. issues regarding the adequately safe surgical margins and the management of the resultant defect through modern wound dressing technologies are discussed. keywords : giant basal cell carcinoma, modern dressing, gel...

OBJECTIVE To investigate an appropriate depth of needle insertion during trigger point injection into the rhomboid major muscle. METHODS Sixty-two patients who visited our department with shoulder or upper back pain participated in this study. The distance between the skin and the rhomboid major muscle (SM) and the distance between the skin and rib (SB) were measured using ultrasonography. Th...

Background: Colorectal carcinoma is the third most common cause of death in Iran. This study was performed in order to determine the appropriate distal clearance margin (DCM) for resection of rectal cancer in patients who undergo neoadjuvant chemoradiotherapy for sphincter preserving procedure. Materials and Methods: This was a cross-sectional study conducted in Shahid Faghihi Hospital of Shira...

Pelvic bone tumor resection is challenging due to complex geometry, limited visibility, and restricted workspace. Accurate resection including a safe margin is required to decrease the risk of local recurrence. This clinical study reports 11 cases of pelvic bone tumor resected by using patient-specific instruments. Magnetic resonance imaging was used to delineate the tumor and computerized tomo...

PURPOSE To evaluate outcomes of lid margin split with cryotherapy to the anterior lid lamella for treating trichiasis. METHODS This prospective study included 20 eyelids of ten patients with trichiasis who were treated with lid margin split and cryotherapy. All patients were followed up for 6 months. RESULTS Eighteen eyelids (90%) were successfully treated, and two eyelids (10%) developed r...

Graph as a common structure of machine learning, has played an important role in many learning tasks such as graph-based semi-supervised learning (GSSL). The quality of graph, however, seriously affects the performance of GSSL; moreover, an inappropriate graph may even cause deteriorated performance, that is, GSSL using unlabeled data may be outperformed by direct supervised learning with only ...

The goal of hyptensive anesthesia is the safe reduction of intraoperative blood loss, thus reducing transfusion risks.  Previous hypotensive technics had a narrow margin of safety in that cardiac output was usually reduced in proportion to the degree of induced hypotension. This is in contrast to the results of our study, in which Sodium Nitroprusside was used as the sole hypotensive agent. Ni...

BACKGROUND Paraglottic space (PGS) is a connective tissue compartment of the larynx and is important in the extension of laryngeal cancer. It communicates with the preepiglottic space superiorly and with the extralaryngeal region inferiorly through the gap within the cricothyroid membrane. Transglottic cancer of the larynx, which spreads within PGS, is characterized by a high incidence of laryn...

BACKGROUND It is imperative that bone tumour margin and extent of tumour involvement are accurately assessed pre-operatively in order for the surgeon to attain a safe surgical margin. In this study, we comprehensively assessed each of the findings that influence surgical planning, on various MRI sequences and compared them with the gold standard - pathology. MATERIAL/METHODS In this prospecti...
