Background: Magnetic resonance imaging of the breast has emerged as a valuable imaging tool in addition to conventional imaging modalities. It has high sensitivity for malignant lesions, and can detect mammographically, sonographically and clinically occult cancers. “MR only” lesions are best biopsied under MR guidance; however, this may be a challenging task.

Objectives:  To evaluate our initial clinical experience with MR-guided core needle breast biopsy and MR-guided needle localization.

Methods: We retrospectively evaluated 81 women with 97 lesions, who were scheduled for guided core needle biopsy or MR-guided needle localization followed by surgery. Lesions were categorized as malignant, high risk, or benign according to the BI- RADS MR classification system. MR findings were compared with final histopathology or with follow-up imaging findings.

Results: Fifteen (16%) lesions were malignant (9 invasive ductal carcinoma, 2 invasive lobular carcinoma, 4 ductal carcinoma in situ); 7 (7%) lesions were high risk (4 atypical ductal hyperplasia, 3 radial scars); 75 (77%) lesions were benign, mainly fibrocystic changes. Other benign findings were sclerosing adenosis, pseudoangiomatous stromal hyperplasia, fat necrosis, intraductal papilloma, fibroadenoma, capillary hemangioma, and florid ductal hyperplasia. No major complications were encountered.
Conclusions: MR-guided interventional procedures of the breast are accurate, safe and feasible methods for sampling breast lesions detected only by MR and have become a significant tool in the management of certain patients.

Head and neck cancer is the sixth most common cancer worldwide. HNCs[1] can originate in the skin or soft tissue, in the upper aerodigestive tracts (oral cavity, oropharynx, hypopharynx, larynx, nasopharynx, paranasal sinuses, salivary glands), or in the thyroid. In each of these sites, tumors vary not only by the primary site but also by pathophysiology, biological behavior and sensitivity to radiotherapy or chemotherapy. Management should be planned according to the tumor's characteristics, patient factors and expertise of the medical team. The main goals of therapy are ablation of the cancer while minimizing morbidity and preserving function and cosmesis. A multidisciplinary team is needed to achieve these goals. Early-stage HNC (stage I and II) should be managed with a single modality, and advanced tumors (stage III and IV) with multimodality therapy. Treatment should be directed to the primary tumor and the area of its lymphatic drainage – the neck lymph nodes. Evidence of metastases in the neck necessitates comprehensive clearance of regional lymphatic basins. However, even if there is no evidence of lymph nodes metastases, when the risk for positive neck lymph nodes exceeds 15–20% elective neck dissection is indicated. Advances in minimally invasive techniques now enable reliable microscopic and endoscopic procedures that mimic the open approaches. Development of contemporary surgical techniques and reconstructive means will help improve the quality of life of patients and prolong survival.

Background: Fracture of the scaphoid is the most common fracture of a carpal bone. Nevertheless, the diagnosis of SF[1] might be challenging. Plain X-rays that fail to demonstrate a fracture line while clinical findings suggest the existence of such a fracture is not uncommon. Currently there is no consensus in the literature as to how a clinically suspected SF should be diagnosed, immobilized and treated.

Objectives: To assess the current status of diagnosis and treatment of clinically suspected scaphoid fractures in Israeli emergency departments

Methods: We conducted a telephonic survey among orthopedic surgeons working in Israeli EDs[2] as to their approach to the diagnosis and treatment of occult SF.

Results: A total of 42 orthopedic surgeons in 6 hospital EDs participated in the survey. They reported performing a mean of 2.45 ± 0.85 clinical tests, with tenderness over the snuffbox area being the sign most commonly used.  A mean of 4.38 ± 0.76 X-ray views were ordered for patients with a clinically suspected SF. The most common combination included posterior-anterior, lateral, semipronated and semisupinated oblique views. All participating surgeons reported immobilizing the wrists of patients with occult fractures in a thumb spica cast based on their clinical findings. Upon discharge from the ED patients were advised to have another diagnostic examination as follows: 29 (69%) repeated X-rays series, 18 (43%) were referred to bone scintigraphy and 2 (5%) to computed tomography; none were referred to magnetic resonance imaging.

Conclusions: No consensus was found among Israeli orthopedic surgeons working in EDs regarding the right algorithm for assessment of clinically suspected SF. There is a need for better guidelines to uniformly dictate the order and set of tests to be used in the assessment of occult fractures.

Background: Subcutaneous allergen immunotherapy is effective in treating allergic airway disease. Disadvantages include immediate local and systemic adverse reactions and poor compliance.

Objectives: To obtain real-life efficacy and safety data through a prospective observational study of SIT[1] in the allergist's office.

Methods: We prospectively collected data from all patients with a diagnosis of allergic rhinitis and/or asthma and a specific immunoglobulin E-mediated sensitization to one or more aeroallergens who began SIT during the 2 year period 1 January 2005 to 31 December 2006. As part of the routine immunotherapy care patients were asked to complete a disease activity questionnaire before and yearly during the treatment. The primary outcome measure was the combined rhinitis and asthma symptoms scores. Data from patients completing at least 1 year of immunotherapy were analyzed.

Results: Altogether, 133 enrolled patients with a mean age of 22.7 years completed at least 1 year of SIT. The allergic rhinitis and asthma disease activity score decreased from a mean of 8.1 to 3.3 (rhinitis) and from 4.8 to 2.4 (asthma) on a 10 cm visual analogue scale after 1 year of SIT (P < 0.001 for all comparisons). Rhinitis medication use in all patients and asthma medication use in asthmatics decreased significantly. Mild local adverse reactions were almost universal. There were 11 patients (8%) who developed 14 immediate systemic, mild to moderate reactions. All reactions were successfully treated in the clinic; none required additional observation or hospitalization.

Conclusions: In the hands of experienced allergists subcutaneous allergy immunotherapy is a safe and efficacious option for patients with allergic rhinitis and asthma.
