In patients who have undergone surgery and radiotherapy for oral squamous cell carcinoma (OSCC), the posterior oral rehabilitation may prove complex. In addition to the defects produced by surgical ablation of the primary tumor, radiotherapy induces deleterious effects upon the oral tissues. We present the case of a 48-year-old male treated two years before due to OSCC in the retromolar trigone...

Skin carcinoma, particularly basal cell carcinoma, and its treatment can result in large defects of the hairy skull. A 53-year-old man is described who was surgically treated for a large basal cell carcinoma invading the skin and underlying tissue at the top of the hairy skull. Treatment consisted of resecting the tumor and external part of the skull bone. To protect the brain and to cover the ...

Clinical case A partial resection of the sternum was performed on a 48 year old female patient with benign sternal tumor. The middle third of the sternum and the adjacent parts of left and right third ribs were resected. Reconstruction of the postoperative 7/6 cm. bone defect was achieved using titanium implant “LeyTM prosthesis”, Geister, Germany. 5 years after surgery the patient complained o...

A 55-year-old man developed progressive dysphagia 14 months after palliative colectomy and subsequent systemic chemotherapy for advanced cecal cancer with carcinomatosis peritonei. Radiologic and endoscopic examinations suggested a submucosal tumor in the lower esophagus causing a severe luminal stricture. A self-expanding metal stent was placed for palliation. The prosthesis was effective for ...

background:  conventional treatments after complicated injuries of the distal radioulnar joint (druj) such as darrach and kapandji-sauvé procedures have many drawbacks, which may eventually lead to a painful unstable distal ulna.  the development of druj prosthesis has significantly evolved over the past years. in this study, we assessed the outcome results of patients after druj implant arthro...

Streaking artifacts on computed tomography (CT) images are caused by high density materials such as hip prosthesis, surgical clips and dental fillings. The artifacts can lead to compromised clinical outcome due to the inability to differentiate tumor volume and the uncertainties in dose calculation. The goals of our study are to evaluate how GE’s smart metal artifact reduction (MAR) algorithm i...

conclusions moderate ppm has no negative effect on echocardiographic trans-aortic pressure gradients or the patients’ nyha functional status after avr with a carbomedics prosthesis in the mid-term follow up. results of the 66 studied patients, 39 were male and 27 were female. the mean age of the patients was 43 ± 17 with a range of 6 - 76 years. implanted sizes of the carbomedics av prosthesis ...

Verrucous carcinoma (VC) is an unusual, well differentiated, and low-grade type of squamous cell carcinoma, characterized by benign histology and cytology but markedly invasive clinical behavior. They have a predilection for squamous mucosae, particularly those of the head and neck region. Many factors have been associated with its pathogenesis, including the presence of previous skin lesions; ...

Giant cell tumor (GCT) of the distal end of the ulna is an uncommon site for primary bone tumors. When it occurs, en-bloc resection of the distal part of the ulna with or without reconstruction stabilization of the ulnar stump is the recommended treatment. We present a case of a 56-year-old man with a GCT of the distal ulna treated successfully with an en-bloc resection of the distal ulna with ...
