BACKGROUND Osteoid osteomas are benign bone-forming tumors characterized by local inflammation and pain. They are also characterized by a small osteolytic lesion (nidus). Spondylolysis is a defect of the pars interarticularis, which may lead to stress fractures, and is a common cause of low back pain in adolescence. Osteoid osteoma occurs predominantly in the posterior elements of the spine. Ma...

STUDY DESIGN Case report and systematic review of the literature. OBJECTIVE To describe a rare case of remodeling of the cervical facet joint after the microendoscopic resection of an osteoid osteoma. SUMMARY OF BACKGROUND DATA Osteoid osteoma, the third most common benign bone tumor, is often treated by image-guided percutaneous removal of the nidus. However, percutaneous resection poses t...

The long-term outcomes of gamma knife surgery (GKS) in patients with posterior fossa arteriovenous malformations (AVMs) were retrospectively analyzed in 82 patients followed up for more than 5 years to evaluate the efficacy and safety. The median AVM volume at GKS was 0.95 cm(3). The prescribed dose to the AVM margin was median 18 Gy with 1-18 isocenters. The actual complete AVM obliteration ra...

Introduction: Deep AVMs are more difficult to operate compared with other supratentorial locations due to the long working corridor through the brain, location in eloquent areas and vicinity with brain critical structures. Material and Method: We report a series of 7 cases with deep AVMs operated in the Fourth Department of Neurosurgery, Emergency Clinical Hospital BagdasarArseni, between 2009 ...

This study was conducted to investigate the antifungal potential and cytotoxicity of selected medicinal plants from Malaysia. The extracts from the stem of Cissus quadrangularis and the leaves of Asplenium nidus, Pereskia bleo, Persicaria odorata and Sauropus androgynus were assayed against six fungi using p-iodonitrotetrazolium-based on colorimetric broth microdilution method. All the plant ex...

High-frequency chest wall oscillation (HFCWO) therapy is one of the techniques to facilitate draining a patient’s lung secretion in pathological situations, and smart with HFCWO devices equipped multiple actuators can be achieved via locating nidi lung. In this paper, through developing novel acoustic spatial model utilizing imaging simulation, new effective method for assessing function presen...

We treated 58 patients with osteoid osteoma by CT-guided radiofrequency ablation (RF). In 16 it followed one or two unsuccessful open procedures. It was performed under general anaesthesia in 48, and spinal anaesthesia in ten. The nidus was first located by thin-cut CT (2 to 3 mm) sections. In hard bony areas a 2 mm coaxial drill system was applied. In softer areas an 11-gauge Jamshidi needle w...

OBJECTIVE To introduce a method that can be performed with minimal equipments available to most orthopedic surgeons and precludes the extensive anesthetic and ablative requirements. METHODS A percutaneous lead tunnel was first established in the cortex next to the nidus under computerized tomography guidance with local anesthesia; then the nidus was curetted in the operating room through the ...

INTRODUCTION Lungs and liver are the most common sites of colorectal cancer metastases after regional lymph nodes, but metastases to unusual sites are reported. Heterotopic bone formation in soft tissues from colorectal cancer is a rare metastatic occurrence. CASE PRESENTATION We present the case of a 29-year-old Caucasian man affected by colon adenocarcinoma with multiple soft tissue metasta...
