ABSTRACTObjective: The Advisory Council of the American Red Cross Disaster Services requested that an independent study determine whether first-aid providers without professional mental health training, when confronted with people who have experienced a traumatic event, offer a “safe, effective and feasible intervention.”Methods: Standard databases were searched by an expert panel from 1990 to September 2010 using the keyword phrase “psychological first aid.” Documents were included if the process was referred to as care provided to victims, first responders, or volunteers and excluded if it was not associated with a disaster or mass casualty event, or was used after individual nondisaster traumas such as rape and murder. This search yielded 58 citations.Results: It was determined that adequate scientific evidence for psychological first aid is lacking but widely supported by expert opinion and rational conjecture. No controlled studies were found. There is insufficient evidence supporting a treatment standard or a treatment guideline.Conclusion: Sufficient evidence for psychological first aid is widely supported by available objective observations and expert opinion and best fits the category of “evidence informed” but without proof of effectiveness. An intervention provided by volunteers without professional mental health training for people who have experienced a traumatic event offers an acceptable option. Further outcome research is recommended.(Disaster Med Public Health Preparedness. 2012;6:247–252)
Voice dysfunction after thyroidectomy may be caused by damage to laryngeal nerves or lesions to strap muscles with laryngo-tracheal movement impairment. Injury to an external branch of the superior laryngeal nerve (EBSLN) is sometimes difficult to recognize clinically and its electromyographic incidence ranges from 0% to 58%. In this study we evaluated, 12-18 months postoperatively, 45 patients who had undergone thyroid surgery (6 total lobectomy, 5 subtotal thyroidectomy, and 34 total thyroidectomy), using a subjective interview, laryngeal videostroboscopy and spectrographic analysis with a multidimensional voice program. Vocal parameters included fundamental frequency, jitter, shimmer, noise-to-harmonic-ratio (NHR) and degree of sub-harmonics. Laryngeal electromyography (LEMG) of the cricothyroid (CT) muscles was performed in 21 subjects with voice problems (35 EBSLNs) using a modified method for the CT recording. In 3 patients of this group (14%) LEMG documented a unilateral EBSLN injury. Easy voice fatigue and decreased pitch range were the most common symptoms after surgery. Average values of vocal parameters pre- and postoperatively in patients without neural damage (n = 42) were: jitter 0.64% and 0.78%, shimmer 3.25% and 3.54%, and NHR 0.12% and 0.13%, respectively (P > 0.05). Acoustic analysis revealed altered patterns in some patients with no objective evidence of damage to EBSLNs, suggesting an extralaryngeal cause of vocal dysfunction, such as laryngo-tracheal fixation or lesions to strap muscles. We conclude that laryngeal videostroboscopy and spectrographic analysis are very useful to assess voice problems after thyroidectomy, including in patients without LEMG-proven neural lesions, in order to suggest early speech rehabilitation, especially in professional voice users.
The purpose of this study was to assess the anatomic and functional outcomes and compare the voice quality in patients affected by T1a glottic carcinoma treated with curative intent with radiotherapy or laser cordectomy. Fifty-seven cases were analysed: 27 after curative radiotherapy and 30 after laser cordectomy. All patients were studied with videolaryngostroboscopy, voice analysis by narrow spectrogram, and vocal parameters (Jitter, Shimmer, noise/harmonic ratio, and diplophonia). Videolaryngostroboscopy showed severe glottic inadequacy in 25% of cases treated with radiation and insufficient compensation 'ventricular band' or 'with arytenoid hyperadduction' in 65% of cases after surgery. Severe dysphonia on the electro-acoustic analysis of voice was observed in 25% of cases after radiation and 70% after laser (p < 0.001). Fundamental frequency and vocal parameters showed more favourable results in the radiation group (p < 0.001). Voice assessment showed better results after radiotherapy compared with laser cordectomy. Voice outcome should be carefully considered in the treatment decision for T1 glottic carcinoma.
In order to better define the anatomical and clinical importance of the deep parotid lymph nodes, the surgical specimens obtained from a series of 18 total parotidectomies were evaluated. In 10 cases primary parotid pathology was found, whereas in the remaining eight cases metastases to glandular lymph nodes were present.One hundred and forty-nine lymph nodes, in all, were identified (range 3-14, average 8.2, mean 8), 118 located in the superficial parotid lobe (range 3-11, average 6.5, mean 7), and 31 in the deep lobe (range 0-5, average 1.7, mean 2).In the group of patients with oncological pathology, of the total 64 lymph nodes examined, 21 were found to be sites of metastasis, 11 in the superficial lobe, and 10 in the deep lobe.The above findings confirm the anatomical and oncological importance of the deep parotid lymph nodes, and highlight the necessity of a total parotidectomy in all cases in which intraglandular spread of lymph node metastases is certain or suspect.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
