Healing the healer: one step at a time.

Health care workers have the most challenging of professions. They are expected to work long hours while demonstrating compassion and care for the patients that they serve. Although health care practitioners are among the most disciplined of working professionals, they are often some of the unhealthiest of individuals, facing enormous amounts of stress in their lives. Healing the Healer: One Step at a Time is a 6-week health fitness program. It explores the unique challenges faced in the field of health care and teaches techniques to address those challenges head on. Healing the Healer uses Nordic walking as the exercise portion of the class. The case study examines the structure, purpose, and design of this 6-week course. Special attention is given to four basic sections: balance, pacing, joy, and discipline. The arguments presented in this article are theory based and supported by case study evidence.

Supraglottic laryngeal cancer: analysis of treatment results.

OBJECTIVE: This study reports the results of treatment for supraglottic laryngeal cancer with nine different treatment modalities with long-term follow-up. STUDY DESIGN: Retrospective study of 653 patients with supraglottic laryngeal squamous cell cancer treated from April 1955 to January 1999. METHODS: The study population included previously untreated patients with cancer of the supraglottic larynx treated with curative intent by one of nine treatment modalities and who were eligible for 5-year follow-up. The treatment modalities included subtotal supraglottic laryngectomy (SSL), SSL with neck dissection (SSL/ND), total laryngectomy (TL), TL/ND, radiation therapy (RT), SSL/RT, SSL/ND/RT, TL/RT, and TL/ND/RT. Multiple diagnostic, treatment, and follow-up parameters were studied using standard statistical analysis to determine significance. RESULTS: None of the nine treatment modalities produced a survival advantage, either overall or within the stages. Overall disease specific survival (DSS) by treatment modality included SSL 88.9%, SSL/ND 75.8%, TL 83.3%, TL/ND 66.7%, RT 47.2%, SSL/RT 68.9%, SSL/ND/RT 68.1%, TL/RT 59.3%, and TL/ND/RT 46.7%. Improved DSS and cumulative disease specific survival rates were associated with patients under the age of 65 years (P = .0001), early stage disease, N0 disease (P = .0001), clear resection margins (P = .0094), and no recurrence (P = .0001). Posttreatment function showed that 90% of patients were functional in everyday life, 90.7% were eating satisfactorily, 91.4% were breathing naturally, and 83% of SSL patients, 85.7% of RT patients, and 52.8% of TL patients had "good" voices. Laryngeal preservation was accomplished in 86.1% of SSL patients and 72.7% of RT patients (P = .0190). CONCLUSIONS: No treatment modality produced a survival advantage. Because SSL produced the best rate of laryngeal preservation, we recommend its use in treating the primary in eligible patients. The importance of clear resection margins is stressed. Patients with N+ disease should have the neck treated. Patients with N0 disease may be observed safely with no loss of survival advantage. Because of the pattern of recurrence and the high rates of distant metastasis and second primary cancers, follow-up for a period of not less than 8 years is recommended.

Management of stage IV glottic carcinoma: therapeutic outcomes.

OBJECTIVES/HYPOTHESIS: The best therapeutic approach for the treatment of stage IV glottic carcinoma is controversial. STUDY DESIGN: A retrospective study. METHODS: A retrospective study of Tumor Research Project data was performed using patients with stage IV glottic squamous cell carcinoma treated with curative intent by five different treatment modalities from 1955 to 1998 at Washington University School of Medicine and Barnes-Jewish Hospital (St. Louis, MO). RESULTS: Ninety-six patients with stage IV glottic carcinoma were treated by five modalities: total laryngectomy (TL) (n = 13), total laryngectomy with neck dissection (TL/ND) (n = 18), radiation therapy alone (RT) (n = 7) (median dose, 69.5 Gy), total laryngectomy combined with radiation therapy (TL/RT) (n = 10), and total laryngectomy and neck dissection combined with radiation therapy (TL/ND/RT) (n = 48). The overall 5-year observed survival (OS) rate was 39%, and the 5-year disease-specific survival (DSS) rate was 45%. The 5-year DSS rates for the individual treatment modalities included the following: TL, 58.3%; TL/ND, 42.9%; RT, 50.0%; TL/RT, 30.0%; and TL/ND/RT, 43.9%. There was no significant difference in DSS for any individual treatment modality (P =.759). The overall locoregional control rate was 69% (66 of 96). The overall recurrence rate was 39% with recurrence at the primary site and in the neck at 19% and 17%, respectively. Recurrence was not related to treatment modality. The 5-year DSS after treatment of locally recurrent cancer (salvage rate) was 30% (3 of 10) and for recurrent neck disease (28 of 67) was 42%. The incidence of delayed regional metastases was 28%; of distant metastasis, 12%; and of second primary cancers, 9%. There was no statistically significant difference in survival between node-negative (N0) necks initially treated (5-y DSS, 31%) versus N0 necks observed and later treated if necessary (5-y DSS, 44%) (P =.685). CONCLUSION: The five treatment modalities had statistically similar survival, recurrence, and complication rates. The overall 5-year DSS for patients with stage IV glottic carcinoma was 45%, and the OS was 39%. The cumulative disease-specific survival (CDSS) was 0.4770 with a mean survival of 10.1 years and a median survival of 3.9 years. Patients younger than age 55 years had better survival (DSS) than patients 56 years of age or older (P =.0002). Patients with early T stage had better survival than patients with more advanced T stage (P =.04). Tumor recurrence at the primary site (P =.0001) and in the neck (P =.014) and distant metastasis (P =.0001) had a deleterious effect on survival. Tumor recurrence was not related to treatment modality. Patients with clear margins of resection had a statistically significant improved survival (DSS and CDSS) compared with patients with close or involved margins (P =.0001). Post-treatment quality of life was not significantly related to treatment modality. Patients whose N0 neck was treated with observation and appropriate treatment for subsequent neck disease had statistically similar survival compared with patients whose N0 neck was treated prophylactically at the time of treatment of the primary. A minimum of 7 years of follow-up is recommended for early identification of recurrent disease, second primary tumors, and distant metastasis. None of the standard treatment modalities currently employed has a statistical advantage regarding survival, recurrence, complications, or quality of life.

Carcinoma of paranasal sinuses: long-term outcomes with radiotherapy.

PURPOSE: To assess the clinical features, prognostic factors, results, and complications of treatment of carcinomas of the paranasal sinus. METHODS AND MATERIALS: The records of 106 patients (72 men and 34 women) with paranasal sinus carcinoma treated with curative intent at Washington University between January 1960 and August 1998 were analyzed. Patient age ranged from 29 to 91 years (median, 64 years). Most tumors originated in the maxillary (76%) or ethmoid (18%) sinus. Most tumors were locally advanced at presentation. All patients underwent radiotherapy (RT), combined with surgery in 65%; 2% received chemotherapy. RESULTS: Follow-up ranged from 1.7 months to 24 years (median 5 years). The 5-year local tumor control, locoregional tumor control, disease-free survival (DFS), and overall survival rate was 58%, 39%, 33%, and 27%, respectively. A statistically significant improvement in DFS was noted with the addition of surgical resection to RT (35% vs. 29%, p = 0.05). Nodal status at presentation emerged as a statistically significant predictor for locoregional tumor control and DFS in multivariate analysis. Distant metastases occurred in 29% of patients. CONCLUSION: This review of a large, single-institution experience of paranasal sinus carcinoma patients who underwent RT showed that locoregional tumor progression and recurrence remain predominant patterns of failure despite aggressive local treatment with combined surgery and RT. DFS improved slightly with combined modality treatment. The overall survival rates remained suboptimal, suggesting a need for more accurate determination of tumor extent, as well as more effective locoregional and systemic therapies.

Intensity-modulated radiation therapy for oropharyngeal carcinoma: impact of tumor volume.

PURPOSE: To assess the therapeutic outcomes in oropharyngeal cancer patients treated with intensity-modulated radiotherapy (IMRT) and analyze the impact of primary gross tumor volume (GTV) and nodal GTV (nGTV) on survival and locoregional control rates. METHODS AND MATERIALS: Between February 1997 and September 2001, 74 patients with squamous cell carcinoma of the oropharynx were treated with IMRT. Thirty-one patients received definitive IMRT; 17 also received platinum-based chemotherapy. Forty-three patients received combined surgery and postoperative IMRT. The median follow-up for all patients was 33 months (range, 9-60 months). Fifty-two patients (70.3%) had Stage IV disease, 17 patients (23%) had Stage III, 3 patients (4.1%) had Stage II, and 2 patients (2.7%) had Stage I tumors. The mean prescription dose was 70 and 66 Gy, respectively, for the definitive and postoperative cohorts. The daily fraction dose was either 1.9 or 2 Gy, five times weekly. The GTV and/or nGTV were determined and derived using the Computational Environment for Radiotherapy Research, a free software package developed at Washington University. The mean GTV was 30.5 +/- 22.3 cm(3), and the mean nGTV was 23.2 +/- 20.6 cm(3). RESULTS: Ten locoregional failures were observed. Six patients died of disease and three died of concurrent disease. Distant metastasis developed in 6 patients. The 4-year estimate of overall survival was 87%, and the 4-year estimate of disease-free survival was 81% (66% in the definitive vs. 92% in the postoperative RT group). The 4-year estimate of locoregional control was 87% (78% in the definitive vs. 95% in the postoperative RT group); the 4-year estimate of distant metastasis-free survival was 90% (84% in the definitive vs. 94% in the postoperative group). Multivariate analysis showed that GTV and nGTV were independent risk factors determining locoregional control and disease-free survival for definitive oropharyngeal IMRT patients. The worst late toxicities documented were as follows: 32 patients with Grade 1 and 9 with Grade 2 xerostomia; 2 with Grade 1 and 1 with Grade 2 skin toxicity; 3 with Grade 1 late mucositis; and 3 with Grade 1 trismus. Seventeen patients required gastrostomy tube placement. CONCLUSION: IMRT is an effective treatment modality for locally advanced oropharyngeal carcinoma. The GTV and nGTV are the most important factors predictive of therapeutic outcome.

In search of "the white area": some notes on art in clinical space.

Would you consider looking at two paintings instead of reading a more ritualized abstract? In the first painting, the poet W. B. Yeats shows passages from his autobiography to his friend, the poet and painter George Russell. Russell is appalled to read that there is hardly a single fact accurate: "If you show me the manuscript," he tells Yeats, "I will correct the facts." Yeats airily dismisses the offer: "Oh, I do not want accuracy. I only want a picturesque sentence" (Kiberd, 2003). The second painting is an image I cherish in my mind for years: a photo of the Teatro del Mondo (the theater of the world) created by Aldo Rossi, the late Italian architect, for the 1979 Venice Biennale. Built in the Venice tradition of floating theaters, Rossi created a theater on water, a raft tugged by a boat. Within the panoramic view of Venice, there is a "huge piece of carpentry," which looks like a stageset of a child's dream memory: some big connected play-cubes made of light brown wood on a metal grid of scaffolding, and a blue pointed tower. For Rossi, this theater goes beyond the context of Venice. It is like "the Marine buildings in Maine, the wonderful tall light houses--'the houses of the light'--that observe and are observed...[in a] Venetian method of construction...that seeks fantasy only in the real" (Rossi, 1979).

Analysis of treatment results for base of tongue cancer.

OBJECTIVE: The study reported the results of treatment for base of tongue cancer with five different treatment modalities with long-term follow-up. STUDY DESIGN: This was a retrospective study of 262 patients with base of tongue cancer treated in the Departments of Otolaryngology-Head and Neck Surgery and Radiation Therapy at Washington University School of Medicine (St. Louis, MO) from July 1955 to January 1998. METHODS: The study population included previously untreated patients with biopsy-proven squamous cell carcinoma of the base of tongue who were treated with curative intent by one of five modalities and were all eligible for 5-year follow-up. The treatment modalities included local resection alone, composite resection alone, radiation therapy alone, local resection with radiation therapy, and composite resection with radiation therapy. Multiple diagnostic, treatment, and follow-up parameters were studied using standard statistical analysis to determine statistical significance. RESULTS: The overall 5-year disease-specific survival (DSS) was 49.6% with death due to tumor in 50.4%. The 5-year cumulative disease-specific survival probability (CDSS) was 0.526 (Kaplan-Meier) with a mean of 7.8 years and a median of 5.6 years. Patients with early disease had significantly improved DSS compared with patients with more advanced disease (stages I and II; TN stages T1N0, T2N0, and T2N1; and T stages T1 and T2.). Patients with N0 had better DSS than patients with positive lymph nodes (P =.010). The DSS for all stages by treatment modality included local resection (70.0%), composite resection (47.6%), radiation therapy (40.4%), local resection and radiation therapy (50.0%), and composite resection with radiation therapy (51.5%). Overall and within the stages there was no significant difference in either DSS or CDSS by treatment modality. Local-regional recurrence occurred in 26% of patients, and overall salvage was 10.5%. Patients with clear resection margins did better than patients with close or involved margins (DSS and CDSS). Patients treated with radiation therapy alone had improved capacity to swallow (P =.001), speak (P =.01), and work (P =.001) compared with patients treated with the other modalities. CONCLUSIONS: Cancer of the base of tongue is a lethal disease, and its treatment results in significant disability. No treatment produced a significantly improved survival advantage. Focus on improving local-regional control might improve overall survival. All treatment modalities were associated with major treatment-related complications. Radiation alone produced significantly improved post-treatment function and quality of life compared with the other modalities. Because of the recurrence rates at the primary and neck sites and the high rates of development of distant metastasis and second primary cancers, patients should be monitored for a minimum of at least 4 years.

Management of T3N0M0 glottic carcinoma: therapeutic outcomes.

BACKGROUND: The best therapeutic approach for the treatment of T3N0M0 (stage III) glottic carcinoma is controversial. METHOD: A retrospective study of Tumor Research Project data were performed using patients with T3N0M0 glottic squamous cell carcinoma treated with curative intent by seven different treatment modalities from January 1950 to December 1996 at Washington University School of Medicine/Barnes-Jewish Hospital. RESULTS: Two hundred patients with T3N0M0 glottic carcinoma were treated using seven modalities: total laryngectomy (TL, n = 30), TL with neck dissection (TL/ND, n = 40), conservation surgery alone (CS, n = 22), radiation therapy alone (RT, n = 29), TL combined with RT (TL/RT, n = 31), TL and ND combined with RT (TL/ND/RT, n = 36), and CS combined with RT (CS/RT, n = 12). The overall 5-year observed survival rate (OS) was 54% and the 5-year disease-specific survival rate (DSS) was 67%. The 5-year DSS for the individual treatment modalities included TL, 65.4%; TL/ND, 76.5%; CS, 71.4%; RT, 56.5%, TL/RT, 51.9%; TL/ND/RT, 71.4%; and CS/RT, 80%. There was no significant difference in DSS for any individual treatment modality (P =.375). The overall local and regional control rate was 74% (148 of 200). The overall recurrence rate was 37.5% with recurrence at the primary site and in the neck of 19.5% and 11%, respectively. Recurrence was not related to treatment modality. The 5-year DSS after treatment of recurrent cancer (salvage rate) was 35.8%. The incidence of distant metastasis was 11% and for second primary cancers it was 19.5%. There was no statistically significant difference in survival between necks initially treated (72%, 5-y DSS) versus necks observed and later treated if necessary (70%, 5-y DSS) (P =.797). CONCLUSIONS: The seven treatment modalities had statistically similar recurrence, complication, and survival rates. Patients with clear surgical margins have a significant survival advantage compared with patients with close and involved margins. Because postoperative radiation therapy in patients with positive margins did not improve survival, formal re-resection of the site of the positive margin should be considered. In patients whose N0 neck was not treated electively, close follow-up observation with meticulous examinations combined with appropriate treatment for subsequent neck disease resulted in a similar survival rate compared with those patients whose N0 necks were treated initially. Six-year minimum follow-up is recommended for early identification of primary and neck recurrence and for discovering expected second primary cancers. Patients treated with RT and CS had statistically similar rates of survival, maintenance of voice, and acquired permanent tracheal stoma. CS is a valid alternative to RT in treating highly selected patients with T3N0 glottic carcinoma.

Analysis of treatment results for oral tongue cancer.

OBJECTIVE: The study reports the results of treatment of oral tongue cancer with five different treatment modalities with long-term follow-up. STUDY DESIGN: Retrospective study of 332 patients with oral tongue cancer treated in the Departments of Otolaryngology-Head and Neck Surgery and Radiation Therapy at Washington University School of Medicine (St. Louis, MO) from 1957 to 1996. METHODS: Patients with biopsy-proven squamous cell carcinoma of the oral tongue who were previously untreated and were treated with curative intent by one of five modalities and who were eligible for 5-year follow-up were included. The treatment modalities included local resection alone, composite resection alone (with neck dissection), radiation therapy alone, local resection with radiation therapy, and composite resection with radiation therapy. Multiple diagnostic, treatment, and follow-up parameters were studied using standard statistical analysis to determine statistical significance. RESULTS: The overall 5-year disease-specific survival rate (DSS) was 57% with death due to tumor in 43%. The 5-year cumulative disease-specific survival probability (CDSS) was 0.61 (Kaplan-Meier) with a mean of 17.5 years and a median of 30.1 years. The DSS by treatment modality included local resection (73%), composite resection (61%), radiation therapy (46%), local resection and radiation therapy (65%), and composite resection with radiation therapy (CR/RT) (44%). Overall, local resection had a significantly improved DSS and CR/RT had a decreased DSS that was related to the stage of disease being treated. In treating stage IV disease, CR/RT produced a more significantly improved CDSS than the other treatment modalities. Recurrence at the primary site was as common as recurrence in the neck. Eighty-nine percent of recurrences occurred within the first 60 months. Recurrence significantly decreased survival. DSS was significantly improved in patients with clear margins of resection. Metastasis to a distant site occurred in 9.6% of patients. Twenty-one percent of patients had second primary cancers, and 54% of these patients died of their second primary cancer. CONCLUSIONS: Significant improvement in DSS was seen in patients with clear margins, early stage grouping and clinical (pretreatment) tumor stage, and negative nodes. Significant decrease in DSS was seen in patients with close or involved margins, advanced stage grouping and clinical (pretreatment) tumor staging, positive clinical (pretreatment) node staging, and tumor recurrence. Obtaining clear margins of resection is crucial because it significantly affects survival. A minimum of 5 years of close monitoring is recommended because of the high incidence of second primary cancers.

A meta-analytic review of gender differences in ADHD.

The present study examined gender differences in ADHD through a meta-analysis. Effect size estimates for the primary symptoms and correlates of ADHD were calculated in an attempt to replicate and extend a previous meta-analysis on gender differences in the disorder. Relatively lenient inclusion criteria were used in order to maximize the number of studies included in the effect sizes. The results indicated that in comparison to ADHD boys, ADHD girls had lower ratings on hyperactivity, inattention, impulsivity, and externalizing problems. In addition, ADHD girls had greater intellectual impairments and more internalizing problems than ADHD boys. Overall, the results of the current meta-analysis indicated general agreement with the previous meta-analysis. The clinical implications of these gender differences and future research considerations are discussed.

A preliminary investigation of the construct of psychopathic personality (psychopathy) in chimpanzees (Pan troglodytes).

Although the construct of psychopathy has received considerable attention in humans, its relevance to other animals is largely unknown. We developed a measure of psychopathy for use in chimpanzees (Pan troglodytes), the Chimpanzee Psychopathy Measure (CPM), and asked 6 raters to complete this index on 34 chimpanzees. The CPM (a) demonstrated satisfactory interrater reliability and internal consistency; (b) exhibited marginally significant sex differences (males > females); (c) correlated positively with measures of extraversion, agreeableness, and observational ratings of agonism, sexual activity, daring behaviors, teasing, silent bluff displays, and temper tantrums, and negatively with observational ratings of generosity; and (d) demonstrated incremental validity above and beyond a measure of dominance. Although further validation of the CPM is needed, these findings suggest that the psychopathy construct may be relevant to chimpanzees.

Mania in children with pervasive developmental disorder revisited.

OBJECTIVE: Although a small literature of case reports suggests that mania co-occurs with pervasive developmental disorder (PDD), little is known about this overlap. The authors systematically investigated the overlap between mania and PDD in a consecutive sample of referred youths, examining its prevalence and correlates. It was hypothesized that children with PDD plus manic features have both disorders. METHOD: Subjects were consecutively referred children meeting diagnostic criteria on structured interview for PDD without mania (n = 52), the comorbid condition PDD + mania (n = 14), and mania without PDD (n = 114). All subjects were evaluated using a comprehensive diagnostic battery that included assessment of psychopathology (structured diagnostic interview and Child Behavior Checklist), cognition, and functioning. RESULTS: Of the 727 referred children, 52 met criteria for PDD, 114 met criteria for mania, and 14 met criteria for both. The 14 children with both PDD + mania represented 21% of the PDD subjects and 11% of all manic subjects. Clinical characteristics of PDD were similar in PDD subjects with and without mania, and manic features were similar in manic children with and without PDD. CONCLUSIONS: Children with PDD and mania may suffer from two disorders. Comorbid mania among patients with PDD may be more common than previously thought. Identification of the comorbid condition may have important therapeutic and scientific implications.

Panic disorder and agoraphobia in consecutively referred children and adolescents.

OBJECTIVE: This report examines the clinical features and correlates of juvenile panic disorder in referred children and adolescents to test specific hypotheses about its relationship with adult panic disorder. METHOD: The sample consisted of consecutively referred children and adolescents (N = 472) comprehensively evaluated with structured diagnostic interviews, cognitive tests, and psychosocial assessments. RESULTS: Panic disorder was identified in 6% and agoraphobia in 15% of psychiatrically referred children and adolescents. Children meeting criteria for panic disorder also frequently met criteria for agoraphobia. The latter disorder was more prevalent and had an earlier age at onset than panic disorder. Children with panic disorder and those with agoraphobia had similar correlates with frequent comorbidity with other anxiety and mood disorders. A high level of comorbidity with disruptive disorders was also identified. CONCLUSIONS: These results support the hypothesis of continuity between the juvenile and the adult form of panic disorder. However, the high level of comorbidity with disruptive behavior disorders also suggests developmentally specific discontinuities between juveniles and adults with panic disorder.

A prospective four-year follow-up study of children at risk for ADHD: psychiatric, neuropsychological, and psychosocial outcome.

BACKGROUND: Attention-deficit hyperactivity disorder (ADHD) is a familial disorder that places the siblings of ADHD children at high risk for ADHD, conduct, mood, and anxiety disorders. Although the pattern of psychiatric risk has been well documented by prior family studies, neither the short- nor long-term outcome of these high-risk siblings has been prospectively examined. OBJECTIVE: To document the 4-year psychiatric, psychosocial, and neuropsychological outcome of the siblings of children with ADHD. METHOD: DSM-III-R structured diagnostic interviews and blind raters were used to conduct a 4-year follow-up of siblings from ADHD and control families. The siblings were also evaluated for cognitive, achievement, social, school, and family functioning. RESULTS: At follow-up, significant elevations of behavioral, mood, and anxiety disorders were found among the siblings of ADHD children. The high-risk siblings had high rates of school failure and showed evidence of neuropsychological and psychosocial dysfunction. These impairments aggregated among the siblings who had ADHD. CONCLUSIONS: The siblings of ADHD children are at high risk for clinically meaningful levels of psychopathology and functional impairment. In addition to supporting hypotheses about the familial transmission of ADHD, the results suggest that the high-risk siblings might be appropriate targets for primary preventive interventions.

Reaction of surface lamella of moth spermatozoa to vinblastine.

Previous ultrastructural studies appear to indicate that the lacinate appendages (highly elaborated laminar structures which cover the surface of moth spermatozoa) may be intracellular derivatives of transient microtobules found in the elongating spermatids of these insects. Additional support for this theory is supplied by the present study in which testes of the warehouse moth Ephestia cautella were treated in vivo with the antimitotic agent vinblastine sulphate. Solutions containing 10(-5) M vinblastine caused the lacinate appendages to become poorly resolved, and at 10(3) M they disappeared. This concentration-dependent response of the appendages to vinblastine resembles that of tubulin-containing structures.
