Background: Whole-body integrated positron emission tomography / contrast-enhanced computed tomography (PET/CT) scan is increasingly used in cutaneous lymphomas. However, the value of PET/CT in the detection of cutaneous lesions in primary cutaneous B-cell lymphoma (PCBCL) has barely been investigated.

Objectives: To investigate the diagnostic accuracy of PET/CT in tracking cutaneous involvement in PCBCL.

Methods: A retrospective study was conducted on 35 consecutive patients diagnosed with cutaneous B-cell lymphoma according to the World Health Organization classification who were evaluated with PET/CT as the initial staging procedure before treatment.

Results: Thirty-five patients met the study criteria. In two patients extracutaneous disease was detected by PET/CT and CT and confirmed by biopsy. Of the 33 patients with PCBCL, 26 (79%) had small cell PCBCL (18 marginal-zone, 8 follicle-center lymphoma) and 7 (21%) had large cell PCBCL (3 follicle-center, 3 leg-type, 1 indeterminate). PET/CT detected skin lesions in 3 of 26 patients (12%) with small-cell PCBCL as compared to 6 of 7 patients with large-cell PCBLC (86%), a 7.4-fold detection risk (95% confidence interval, 2.4–22, P = 0.004). The PET-positive subgroup was characterized by larger lesion size (P < 0.001) and a higher Ki-67 proliferation index (P < 0.001).

Conclusions: The sensitivity of PET/CT for detecting cutaneous involvement of lymphomas is low for small-cell PCBCL but high for large-cell types, and thus may facilitate therapeutic strategies.

Background: Treatment guidelines for well-differentiated papillary thyroid carcinoma (PTC) are based on retrospective studies and vary among different professional thyroid associations.

Objectives: To evaluate physician adherence to guidelines, overall and by specialty.

Methods: Questionnaires on the approach to low risk PTC were distributed among 51 surgeons and endocrinologists treating patients with PTC in tertiary medical centers.

Results: A wide range of answers was recorded among physicians regarding the danger posed by low risk PTC to the patient’s life, urgency with which treatment should be administered, type of treatment, and risks associated with this treatment. There was a significant between-group difference in treatment preference: endocrinologists chose total thyroidectomy with radioactive iodine, while surgeons favored hemithyroidectomy alone.

Conclusions: There is a wide difference in treatment recommendations between treating physicians and different specialties with regard to low risk PTC. The wide variation within and between specialties may be explained by biases.

 Background: Smoking is a serious health issue worldwide. Smoking trends among physicians predict similar trends in the general population. Little is known about current smoking rates among physicians.

Objectives: To investigate current smoking trends among Israeli physicians.

Methods: All practicing physicians at a tertiary university-affiliated medical center in central Israel were invited to complete a Web-based questionnaire on smoking habits and smoking-related issues via the institutional email. Findings were compared to those in the general population and between subgroups.

Results: Of the 90 responders (53 male, 88 Jewish), 54 (60%) had never smoked, 21 (23.3%) were past smokers, and 15 (16.7%) were current smokers. The rate of current smokers was lower than in the general population. The proportion of current smokers was higher among residents than attending physicians and among physicians in surgical compared to medical specialties. Past smokers accounted for 17.9% of the residents (average age at quitting 26.2 years) and 28.1% of the attending physicians (average age at quitting 33.0 years). Non-smokers more frequently supported harsh anti-smoking legislation.

Conclusions: The rate of smoking is lower in physicians than in the general population but has not changed over the last 15 years. Anti-smoking programs should particularly target physicians in surgical specialties.

Background: Chondrosarcoma of the larynx is a rare tumor. The most common symptom is hoarseness. Treatment is controversial.

Objectives: To describe six patients with laryngeal chondrosarcoma from a single center.

Methods: The medical records of a major tertiary hospital were reviewed for all patients with laryngeal chondrosarcoma diagnosed and treated from 1959 to 2010. Data on background, clinical treatment and outcome were collected.

Results: Six patients, all males with a mean age of 53.3 years, were identified. Partial laryngectomy was performed in three patients, and total laryngectomy, local excision, and partial cricoidectomy in one patient each. Four patients had a permanent tracheostomy after surgery. One patient required postoperative chemotherapy and one radiotherapy. Follow-up time was 12–216 months (mean 102 months). Recurrence developed in two patients 2 and 8 years after initial treatment and was treated by salvage surgery in both patients. One patient died during the follow-up from an unrelated cause. The others are currently alive.

Conclusions: This study supports earlier reports recommending initial treatment with partial or total laryngectomy for laryngeal chondrosarcoma. Long-term follow-up for recurrence is advised. We recommend preserving the larynx, if possible, even if a permanent tracheostomy is necessary.

Background: Laryngeal obstruction due to bilateral vocal cord immobility in adduction may cause dyspnea, hoarseness and dysphagia and can lead to dependence on a tracheostomy. Treatment poses a challenge because of the opposing functions of the larynx and the risk of neck and laryngeal tissue damage.

Objectives: To describe our experience with endoscopic CO2-laser-assisted posterior ventriculocordectomy without tracheostomy for the treatment of bilateral vocal cord immobility in adduction.

Method: The study group consisted of five male and five female patients aged 17–81 years. The procedure was performed with an endoscope and operating microscope connected to a CO2 laser. A C-shaped incision was made, and the posterior third of one vocal cord, the vocal process of the arytenoid, and the posterior third of the false vocal cord were excised. Tracheostomy was not performed.

Results: The technique allowed for a convenient approach to the difficult-to-view areas of the larynx. The procedure was short and bloodless, with minimal damage to laryngeal tissue and no local edema. Hospitalization time was short. Postoperatively, patients had sufficient breathing and mostly fair to good voice quality. None of the patients had severe aspirations and only three patients had mild aspirations.

Conclusions: We recommend this procedure for patients with bilateral vocal cord immobility prior to tracheostomy. Delaying surgery beyond the time of possible re-innervation may place the patient at risk of decompensation, which requires tracheostomy.

Background: Technetium-99m sestamibi scintigraphy has become one of the most popular techniques for localization of the parathyroid gland after failure of primary neck exploration.

Objective: To examine the efficacy of sestamibi with the hand-held gamma ray detecting probe for the identification of parathyroid adenomas during revision parathyroidectomy.

Methods: We reviewed six cases of probe-assisted neck exploration for parathyroid lesions following unsuccessful primary exploration.

Results: In all cases, the pathologic glands were successfully detected and removed.

Conclusions: With careful planning, a gamma ray detecting probe can be used optimally at 2–3 hours after technetium-99m sestamibi injection. The probe is efficient, easy and convenient to use.
