The skin of the head and neck is a common subsite for MCC with distinctions in management from other anatomic areas. Given the rapid pace of developments regarding MCC pathogenesis (Merkel cell polyoma virus (MCPyV)-positive or virus-negative, cell of origin), diagnosis, staging and treatment, and up to date recommendations are critical for optimizing outcomes. This review aims to summarize currently available literature for MCC of the head and neck. The authors reviewed current literature, including international guidelines regarding MCC pathogenesis, epidemiology, diagnosis, staging, and treatment. Subsequently recommendations were derived including the importance of baseline imaging, MCPyV serology testing, primary site surgery, nodal evaluation, radiotherapy, and the increasing role of immune modulating agents in MCC. MCPyV serology testing is increasingly important with potenti...

Research paper thumbnail of Survival Impact of Time to Initiation of Adjuvant Radiation for Merkel Cell Carcinoma: an analysis of the National Cancer Database

METHODS AND MATERIALS The National Cancer Database was queried for patients with MCC of the head and neck, trunk, or extremities diagnosed between 2006 and 2014. Patients who did not undergo resection or receive adjuvant RT within 180 days of surgery were excluded. TTI was defined as the time from resection to first RT fraction. Linear regression was used to define factors associated with TTI. Recursive partitioning analysis modeling was performed to determine an optimal threshold for TTI. Cox proportional hazards modeling was performed to define covariates associated with OS. RESULTS A total of 2293 patients were included in this study. The median TTI for the cohort was 62 days (interquartile range, 43-86 days). TTI was not associated with OS for the overall cohort by multivariable Cox modeling (P = .19). Age, treatment facility type, lymph node examination, anatomic subsite, and surgical margin were associated with TTI (P < .05). Age, sex, insurance status, Charlson-Deyo comorbidity score, lymph node examination status, tumor size, and surgical margin were associated with OS (all P < .05). CONCLUSIONS Increased TTI of adjuvant RT was not associated with OS for patients with early stage MCC in this analysis of the National Cancer Database. The median TTI of 62 days from resection to adjuvant RT initiation for our study cohort contextualizes TTI on a national level and may offer reassurance for patients with prolonged postoperative wound healing or intercurrent illness delaying immediate RT initiation. Despite the lack of a clear detriment to survival with increased TTI up to 180 days from surgery, unnecessary delays in initiating adjuvant therapy should continue to be minimized while ensuring optimal recovery from resection.

Retrospective chart review. Tertiary academic medical center. One hundred fifty-nine patients were identified who underwent salvage total laryngectomy. Pathology reports were reviewed, and all laryngectomy specimens that did not contain residual malignancy were reevaluated for evidence of invasive fungal elements. Twelve of 159 (7.5%) patients who underwent total laryngectomy after primary radiotherapy or chemoradiotherapy had no evidence of residual malignancy. Each of these specimens contained histopathologic evidence of CRN; invasive fungal elements were identified in 25%. There was no statistical difference in demographic or treatment-related variables between patients who underwent salvage total laryngectomy with evidence of persistent or recurrent malignancy in the larynge...

Twenty patients were determined to require exenteration for definitive treatment from 2005 to 2014. Fourteen patients underwent OP and 6 patients received exenteration with adjuvant CRT. Exenteration free survival (EFS), locoregional control (LRC), progression-free survival (PFS), and overall survival (OS) were estimated. Five patients (36%) receiving OP had complete disease response at time of surgery. With a median follow-up of 18.8 months, EFS was 62% at 2 years for patients undergoing OP. At 2 years, there were no significant differences in LRC, PFS or OS (all all p > 0.050) between the groups. Less grade 3 or greater toxicity was seen in patients undergoing OP (p = 0.003). Visual function was preserved in all patients undergoing OP. For patients with sinonasal cancer, OP may avoid exenteration, offering sim...

To clarify the impact of HPV status on the risk for HNSCC in the postoperative setting. We retrospectively evaluated an institutional cohort of 128 patients with HNSCC patients who had been treated with definitive surgery with or without adjuvant radiotherapy or chemoradiotherapy. Patient, disease, and treatment factors were analyzed as potential prognostic indicators. Lymph node extracapsular extension (ECE), perineural invasion (PNI), and lymphovascular space invasion (LVSI) positivity predicted poorer locoregional control (LRC), disease-free survival (DFS), and overall survival (OS). Positive margins related to poorer DFS and OS. HPV status alone did not predict LRC, DFS, or OS. Compared with patients who were HPV-positive and ECE-negative, both HPV-positive and HPV-negati...

All patients with OPSCC presenting to our institutional multidisciplinary clinic from January 2009 to June 2015 were reviewed from a prospective database. The patients were grouped as being at low risk, intermediate risk, and high risk in the manner described by Ang et al. Variance in clinical presentation was examined using χ(2), Kruskal-Wallis, Mann-Whitney, and logistic regression analyses. The rates of HPV/p16 positivity (P&amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;lt;.001), never-smoking (P=.016), and cervical lymph node metastases (P=.023) were significantly higher for patients with OPSCC of the tonsil, base of tongue (BOT), or vallecula subsites when compared with pharyngeal wall or palate subsites. Low-risk patients with tonsil, base of tongue, or vallecula primary tumors presented with nodal stage N2a at a much higher than expected frequency (P=.007), and high-risk patients presented with tumor stage T4 at a much higher than expected frequency (P=.003). Patients with BOT primary tumors who were never-smokers were less likely to have clinically involved ipsilateral neck disease than were former smokers (odds ratio 1.8; P=.038). The distribution of cervical lymph node metastases was not associated with HPV/p16 positivity, risk group, or subsite. When these data were compared with those in historical series, no significant differences were seen in the patterns of cervical lymph node metastases for patients with OPSCC. For patients with OPSCC differences in HPV status, smoking history and anatomic subsite were associated with differences in clinical presentation but not with distribution of cervical lymph node metastases. Historical series describing the patterns of cervical lymph node metastases in patients with OPSCC remain clinically relevant.

A recent report described six cases of hypersensitive laryngeal reflex developing a few weeks to 12 months after laryngeal nerve injury. Symptoms were paroxysms of coughing and stridor that progressed in some to brief episodes of complete airway obstruction (3), suggesting that laryngeal nerve injury may be an etiology in the syndrome of episodic laryngospasm. We report a severe laryngospasm at tracheal extubation in a patient with evidence of superior laryngeal nerve injury, presumably from thyroid lobectomy performed 5 yr earlier. The laryngospasm may have represented laryngeal hypersensitivity.

Retrospective review. Prospective parathyroidectomy database covering 1998 to 2007 was reviewed retrospectively. A total of 687 patients underwent parathyroidectomy, including 247 (36%) &amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;gt;65 years old. Discharge was more often on day of surgery in younger patients (42.5% vs. 29.2%, P = .007) and &amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;gt;23 hours for older patients (24.7% vs. 12.3%, P &amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;lt; .0001). Older patients stayed longer in the recovery room (134 vs. 107 minutes, P = .005). Despite postoperative normocalcemia, older patients tended to have persistently elevated parathyroid hormone (PTH) (10.5% vs. 6.4%, P = .07), whereas younger patients had normal PTH (81.6% vs. 70%, P = .0007). PTH levels were low-abnormal (56-110) in younger patients (47% vs. 29%, P = .046), but high-abnormal (&amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;gt;220) in older patients (16.6% vs. 9.55%, P = .009). Overall complication rates were low (6%-8%), with &amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;gt;93% in either group having no major complications. There was no difference in timing or types of complications, except elderly patients were more likely to have cardiac complications (2.83% vs. 0.45%, P = .022). Nearly 700 parathyroidectomies were performed at our institution over 10 years. Elderly patients comprised one third of this population. They were likely to have longer hospital and recovery room stays, and postoperative normocalcemia with elevated PTH, which may actually be a normal finding for these patients, but it warrants further study. The rate, timing, and types of complications were similar between age groups, although elderly patients had more cardiac complications. When properly indicated, parathyroidectomy remains a safe and effective option for management of hyperparathyroidism in elderly patients.

A technetium sestamibi scan was performed preoperatively. Technetium sestamibi and methylene blue dye (7.5 mg/kg) were administered IV on the day of operation. Operative dissection was directed by the gamma probe. Blood samples for PTH assay were obtained before and after excision of an abnormal gland. When an appropriate decrease in the PTH assay was obtained, the exploration was concluded. Persistent PTH elevation instigated further neck exploration.RESULTS: Thirty-six consecutive patients were explored for untreated primary hyperparathyroidism and three for recurrent hyperparathyroidism. Hypercalcemia was corrected in all 39 patients. A single adenoma was found in 32 of 36 patients with untreated primary hyperparathyroidism, and a single abnormal gland was identified in all of those with recurrent hyperparathyroidism. Persistently elevated PTH prompted further exploration in two patients, identifying a second abnormal gland in one and hyperplasia in the other. Minor local complications occurred in 8% (3 of 39) of the patients. Forty-four percent (16 of 36) of the patients were discharged on the day of operation and 83% (30 of 36) within 23 hours after the initial neck exploration for primary hyperparathyroidism. Comparison of charges for MIRP with charges for "standard" neck exploration revealed lower costs with MIRP because of decreased duration of the operation, anesthesia, and hospital stay, and elimination of intraoperative histologic analysis.CONCLUSIONS: MIRP is a safe and effective procedure, resulting in the correction of hypercalcemia in all patients. The combination of intraoperative gamma probe and methylene blue dye allows rapid identification of the abnormal gland with minimal dissection through a small incision. PTH assay after excision provides biochemical confirmation that the abnormal gland has been removed. Most patients undergoing MIRP can be treated on an outpatient basis. Low postoperative complications, a small incision, and rapid return to normal activities resulted in very high patient acceptance of the procedure.

P16 overexpression is widely accepted as a surrogate marker for HPV positivity. A total of 92 serum samples from 75 head and neck squamous cell carcinoma (HNSCC) patients were examined for HPV16 and 18 E7 antibodies by ELISA. Available tissue was tested for HPV-DNA by PCR, and p16 immunohistochemistry was obtained from a deidentified database. Of 75 HNSCC patients, 25 were HPV E7 seropositive. Seropositivity was strongly associated with cancers of the oropharynx, and correlated with positive p16 immunohistochemistry (IHC) and HPV-DNA. Post-treatment serum was available in a limited subset of patients, revealing a decrease in antibody titers following response to treatment. HPV E7 seropositivity correlated with positive tumor HPV-DNA and p16 expression, and was strongly associated with cancers of the oropharynx. E7 serology warrants further study as a potential biomarker in HPV-positive HNSCC.

It is not known if a telehealth intervention would mitigate these changes. To evaluate the impact of a telehealth intervention on QoL and symptom burden in patients undergoing initial treatment for head and neck cancers. A randomized clinical trial comparing the impact on QoL and symptom distress of telehealth intervention and standard care was conducted with 80 patients (45 treatment, 35 control) who had been diagnosed with head or neck cancer and were receiving 1 or more treatment modalities. Treatment group participants responded daily to symptom management algorithms using a simple telehealth messaging device. QoL was evaluated by the Functional Assessment of Cancer Therapy-Head and Neck Scale (FACTHN) and symptom burden by the Memorial Symptom Assessment Scale (MSAS). Control group participants completed assessments while they re...

The rates of HPV/p16 positivity (P&amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;lt;.001), never-smoking (P=.016), and cervical lymph node metastases (P=.023) were significantly higher for patients with OPSCC of the tonsil, base of tongue (BOT), or vallecula subsites when compared with pharyngeal wall or palate subsites. Low-risk patients with tonsil, base of tongue, or vallecula primary tumors presented with nodal stage N2a at a much higher than expected frequency (P=.007), and high-risk patients presented with tumor stage T4 at a much higher than expected frequency (P=.003). Patients with BOT primary tumors who were never-smokers were less likely to have clinically involved ipsilateral neck disease than were former smokers (odds ratio 1.8; P=.038). The distribution of cervical lymph node metastases was not associated with HPV/p16 positivity, risk group, or subsite. When these data were compared with those in historical series, no significant differences were seen in the patterns of cervical lymph node metastases for patients with OPSCC. For patients with OPSCC differences in HPV status, smoking history and anatomic subsite were associated with differences in clinical presentation but not with distribution of cervical lymph node metastases. Historical series describing the patterns of cervical lymph node metastases in patients with OPSCC remain clinically relevant.

A recent report described six cases of hypersensitive laryngeal reflex developing a few weeks to 12 months after laryngeal nerve injury. Symptoms were paroxysms of coughing and stridor that progressed in some to brief episodes of complete airway obstruction (3), suggesting that laryngeal nerve injury may be an etiology in the syndrome of episodic laryngospasm. We report a severe laryngospasm at tracheal extubation in a patient with evidence of superior laryngeal nerve injury, presumably from thyroid lobectomy performed 5 yr earlier. The laryngospasm may have represented laryngeal hypersensitivity.

Retrospective review. Prospective parathyroidectomy database covering 1998 to 2007 was reviewed retrospectively. A total of 687 patients underwent parathyroidectomy, including 247 (36%) &amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;gt;65 years old. Discharge was more often on day of surgery in younger patients (42.5% vs. 29.2%, P = .007) and &amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;gt;23 hours for older patients (24.7% vs. 12.3%, P &amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;lt; .0001). Older patients stayed longer in the recovery room (134 vs. 107 minutes, P = .005). Despite postoperative normocalcemia, older patients tended to have persistently elevated parathyroid hormone (PTH) (10.5% vs. 6.4%, P = .07), whereas younger patients had normal PTH (81.6% vs. 70%, P = .0007). PTH levels were low-abnormal (56-110) in younger patients (47% vs. 29%, P = .046), but high-abnormal (&amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;gt;220) in older patients (16.6% vs. 9.55%, P = .009). Overall complication rates were low (6%-8%), with &amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;gt;93% in either group having no major complications. There was no difference in timing or types of complications, except elderly patients were more likely to have cardiac complications (2.83% vs. 0.45%, P = .022). Nearly 700 parathyroidectomies were performed at our institution over 10 years. Elderly patients comprised one third of this population. They were likely to have longer hospital and recovery room stays, and postoperative normocalcemia with elevated PTH, which may actually be a normal finding for these patients, but it warrants further study. The rate, timing, and types of complications were similar between age groups, although elderly patients had more cardiac complications. When properly indicated, parathyroidectomy remains a safe and effective option for management of hyperparathyroidism in elderly patients.

A technetium sestamibi scan was performed preoperatively. Technetium sestamibi and methylene blue dye (7.5 mg/kg) were administered IV on the day of operation. Operative dissection was directed by the gamma probe. Blood samples for PTH assay were obtained before and after excision of an abnormal gland. When an appropriate decrease in the PTH assay was obtained, the exploration was concluded. Persistent PTH elevation instigated further neck exploration.RESULTS: Thirty-six consecutive patients were explored for untreated primary hyperparathyroidism and three for recurrent hyperparathyroidism. Hypercalcemia was corrected in all 39 patients. A single adenoma was found in 32 of 36 patients with untreated primary hyperparathyroidism, and a single abnormal gland was identified in all of those with recurrent hyperparathyroidism. Persistently elevated PTH prompted further exploration in two patients, identifying a second abnormal gland in one and hyperplasia in the other. Minor local complications occurred in 8% (3 of 39) of the patients. Forty-four percent (16 of 36) of the patients were discharged on the day of operation and 83% (30 of 36) within 23 hours after the initial neck exploration for primary hyperparathyroidism. Comparison of charges for MIRP with charges for "standard" neck exploration revealed lower costs with MIRP because of decreased duration of the operation, anesthesia, and hospital stay, and elimination of intraoperative histologic analysis.CONCLUSIONS: MIRP is a safe and effective procedure, resulting in the correction of hypercalcemia in all patients. The combination of intraoperative gamma probe and methylene blue dye allows rapid identification of the abnormal gland with minimal dissection through a small incision. PTH assay after excision provides biochemical confirmation that the abnormal gland has been removed. Most patients undergoing MIRP can be treated on an outpatient basis. Low postoperative complications, a small incision, and rapid return to normal activities resulted in very high patient acceptance of the procedure.

Research paper thumbnail of Human papillomavirus E7 serology and association with p16 immunohistochemistry in squamous cell carcinoma of the head and neck

P16 overexpression is widely accepted as a surrogate marker for HPV positivity. A total of 92 serum samples from 75 head and neck squamous cell carcinoma (HNSCC) patients were examined for HPV16 and 18 E7 antibodies by ELISA. Available tissue was tested for HPV-DNA by PCR, and p16 immunohistochemistry was obtained from a deidentified database. Of 75 HNSCC patients, 25 were HPV E7 seropositive. Seropositivity was strongly associated with cancers of the oropharynx, and correlated with positive p16 immunohistochemistry (IHC) and HPV-DNA. Post-treatment serum was available in a limited subset of patients, revealing a decrease in antibody titers following response to treatment. HPV E7 seropositivity correlated with positive tumor HPV-DNA and p16 expression, and was strongly associated with cancers of the oropharynx. E7 serology warrants further study as a potential biomarker in HPV-positive HNSCC.

It is not known if a telehealth intervention would mitigate these changes. To evaluate the impact of a telehealth intervention on QoL and symptom burden in patients undergoing initial treatment for head and neck cancers. A randomized clinical trial comparing the impact on QoL and symptom distress of telehealth intervention and standard care was conducted with 80 patients (45 treatment, 35 control) who had been diagnosed with head or neck cancer and were receiving 1 or more treatment modalities. Treatment group participants responded daily to symptom management algorithms using a simple telehealth messaging device. QoL was evaluated by the Functional Assessment of Cancer Therapy-Head and Neck Scale (FACTHN) and symptom burden by the Memorial Symptom Assessment Scale (MSAS). Control group participants completed assessments while they re...
