These registry data demonstrate that a subgroup of patients with noncancer pain experienced prolonged relief with tolerable side effects and modest need for dose escalation during long-term therapy with CR oxycodone.

Background: Injury to the external branch of the superior laryngeal nerve (EBSLN) can result in detrimental voice changes, the severity of which varies according to the voice demands of the patient. Variations in its anatomic patterns and in the rates of identification reported in the literature have discouraged thyroid surgeons from routine exploration and identification of this nerve. Inconsistent with the surgical principle of preservation of critical structures through identification, modern-day thyroidectomy surgeons still avoid the EBSLN rather than identifying and preserving it.

This long-term study has demonstrated that the RF turbinoplasty for allergic rhinitis appears to be an effective and safe tool for treating allergic rhinitis refractory to medical therapy.

Because of its lack of ionizing radiation and excellent soft-tissue contrast, magnetic resonance (MR) imaging is being increasingly used in the evaluation of acute abdominal pain in the pregnant patient. Roughly 2% of all pregnancies are ectopic. Although ectopic pregnancy is usually diagnosed on the basis of a combination of clinical, laboratory, and ultrasonographic findings, it occasionally is initially identified at MR imaging. Thus, it is imperative that the radiologist should be familiar with the variable appearance of ectopic pregnancy at MR imaging and should evaluate for ectopic pregnancy at any time when (a) a patient has positive results of a pregnancy test and (b) an intrauterine pregnancy is not definitively seen. Because of potential issues of fetal safety, a conservative approach should be used for MR imaging in pregnancy. An MR imaging protocol for the evaluation of possible appendicitis in pregnant women is detailed. Specific findings that can aid in the diagnosis of ectopic pregnancy are the lack of an intrauterine pregnancy, isolated hemoperitoneum, tubal masses, hematosalpinx, and interstitial masses. In the differential diagnosis of acute abdominal pain in pregnancy, consideration should be given to the more unusual forms of ectopic pregnancy, such as angular pregnancy, cornual pregnancy, and abdominal pregnancy. Potential mimics of ectopic pregnancy include placental abnormalities, ovarian neoplasms, and corpus luteum cysts.

Targeted RFA with a newly developed articulating device is both feasible and safe for the treatment of painful posterior vertebral body metastatic tumors.

Elective neck dissection has long been a subject of debate among surgeons. The proponents of elective neck dissection base their rationale on studies that show a 30% incidence of occult disease in those situations for which elective neck dissection is recommended. One hundred eighty-two patients with advanced stages of squamous cell carcinoma of the head and neck were studied. All patients had preoperative computed tomography or magnetic resonance imaging, and all patients had some form of radical neck dissection. The sensitivity of clinical exam was compared with the sensitivity of computed tomography or magnetic resonance imaging in ability to detect nodal disease. The sensitivity of clinical exam alone was 71.7%, while the sensitivity of computed tomography or magnetic resonance imaging was 91.1%. Based on physical exam alone, there would be a 39% rate of occult disease; if computed tomography or magnetic resonance imaging data is combined with physical exam, the occult disease rate would drop to 12%. All centers performing elective neck dissection must reassess their rationale or restudy their occult disease rate with computed tomography or magnetic resonance imaging.

These findings support the utility of the NPS for characterizing the multidimensional nature of the neuropathic pain experience and for detecting changes in neuropathic pain with treatment.
