More is not always better: 2 weeks of intensive cognitive processing therapy-based treatment are noninferior to 3 weeks

OBJECTIVE

Although there is mounting evidence that massed treatment for PTSD is both feasible and effective, many questions remain about the optimal length of intensive treatment programs (ITPs), as well as the role of adjunctive services, such as psychoeducation, mindfulness, and yoga. Our setting recently transitioned from a three-week ITP to a two-week program. Adjunctive services were reduced, but the amount of individual CPT between programs remained similar. The present study examined the effectiveness of a two-week ITP based on twice daily individual CPT sessions and evaluated the program's noninferiority to an established three-week ITP using a Bayesian analytical approach.

METHOD

Bayesian linear mixed regression models were used to explore PTSD and depression changes over time, as well as predictors of change. Noninferiority of the two-week ITP to a three-week ITP was also established using a Bayes factor approach.

RESULTS

Results indicate that program participants change meaningfully in both PTSD and depression severity over the course of treatment, and that changes in posttraumatic cognitions predict subsequent changes in these outcomes. Further, the two-week ITP can be considered noninferior to the three-week ITP in both clinical outcomes and overall satisfaction.

CONCLUSIONS

In the context of intensive PTSD treatment, the content of the ITP appears to matter more than its overall length. Shorter programs have the potential to increase access and treatment capacity. Our findings demonstrate the importance of continuous and rigorous program evaluation. Limitations as well as future directions for research, such as identifying the most effective treatment components, are discussed. (PsycInfo Database Record (c) 2023 APA, all rights reserved).

Building strong therapeutic relationships quickly: The effect of the perceived working alliance on veterans' intensive PTSD treatment outcomes

Intensive treatment programs (ITPs) are successful at reducing posttraumatic stress disorder (PTSD) and depression symptoms in veterans. However, the role of the working alliance in the context of ITPs is largely unexplored. The purpose of this study was to examine veteran-rated working alliance with their individual cognitive processing therapy (CPT) provider as a predictor of changes in PTSD and depression symptoms as well as negative posttrauma cognitions in two unique ITP formats. Data were collected from 128 veterans who completed a 2-week ITP, involving 2 × individual CPT/day, as well as 73 veterans who completed a 3-week ITP, involving 1 × group CPT/day and 1 × individual CPT/day. Both ITPs included adjunctive wellness, skills, and psychoeducation services in addition to CPT. Linear mixed-effects models were used to determine whether changes in working alliance predicted changes in PTSD and depression symptoms. Stronger veteran-reported working alliance with their individual CPT therapist, most notably agreement on tasks, predicted significant reductions in both the 2-week and 3-week programs in PTSD (ps = .012 and .002, respectively) and depression symptoms (ps = .009 and .007, respectively) and negative posttrauma cognitions (ps = .009 and .016, respectively). These results highlight the importance of veterans' perceived working alliance with their individual treatment therapists in ITPs. Results suggest that a strong working alliance that is meaningful for treatment outcomes can be developed quickly despite the brevity of this intensive treatment format. Future research should examine ways to facilitate the development of a strong working alliance prior to or as early as possible in ITPs. (PsycInfo Database Record (c) 2022 APA, all rights reserved).

Delivering Intensive PTSD Treatment Virtually: The Development of a 2-Week Intensive Cognitive Processing Therapy-Based Program in Response to COVID-19

Of the many vulnerable groups affected by the spread of COVID-19, veterans have been especially impacted by the pandemic. Beginning in March 2020, nationwide shelter-in-place orders rapidly led to widespread job loss and economic upheaval; disruption and breakdown of multiple support systems; and increases in family stress, all of which may exacerbate underlying PTSD symptoms. Although telehealth has proven an effective means of delivering evidence-based psychotherapies for PTSD, little is known about the delivery of these treatments in an intensive, daily format over telehealth. There is growing need for intensive treatment options to reduce treatment-interfering barriers such as high dropout rates. In order to address this gap in the literature, this paper details several design considerations as well as patient selection procedures for a 2-week virtual intensive treatment program (vITP) for veterans with posttraumatic stress disorder (PTSD), consisting of daily individual Cognitive Processing Therapy (CPT) and other adjunctive interventions. We also describe two cases of veterans who successfully completed the vITP including their clinical outcomes, therapist reflections on the process, feedback regarding the program, as well as challenges patients encountered with the telehealth platform. Intensive evidence-based psychotherapy for PTSD delivered through a virtual format seems to show promise, but more systemic research is needed.

A case series examining PTSD and depression symptom reductions over the course of a 2-week virtual intensive PTSD treatment program for veterans

OBJECTIVE

Evidence-based treatments for posttraumatic stress disorder (PTSD) can be effectively delivered over telehealth. There are, however, no studies that examine the effectiveness of delivering evidence-based treatments for PTSD in an intensive format via telehealth. Telehealth may be well-suited as a delivery modality because it may address barriers specific to intensive treatments.

METHOD

To address this gap, we report on a case series of ten consecutively enrolled veterans (60% male; mean age 42.3, SD = 6.3) who participated in a virtual 2-week, cognitive processing therapy (CPT)-based intensive program.

RESULTS

All (100%) participants completed treatment and reported large reductions in PTSD and depression symptoms pre- to posttreatment (Hedge's g_ws = 2.83 and g_ws = 1.97, respectively), pre- to 3-month follow-up (Hedge's gws = .99 and g_ws = 1.24, respectively), as well as very high satisfaction.

CONCLUSIONS

Results of this case series suggest that evidence-based treatments for PTSD can be effectively delivered in intensive formats over telehealth and lay the foundation for more rigorously designed and larger scale research comparing virtual to in-person delivered intensive PTSD treatments.

Evaluation of a gender-affirming healthcare curriculum for second-year medical students

Background

Transgender medicine is an emergent subfield with clearly identified educational gaps.

Aims

This manuscript evaluates a gender-affirming healthcare curriculum for second-year medical (M2) students.

Methods

Students received a survey assessing Gender Identity Competency in terms of skills, knowledge and attitudes regarding transgender and gender non-conforming (TGNC) issues. The authors administered the survey before and after the delivery of the curriculum. The curriculum included five online modules, a quiz, a 3-hour case-based workshop and a 2-hour interactive patient-provider panel.

Results

Approximately 60% of M2 students (n=77) completed both preassessments and postassessments. The following showed a statistically significant improvement from preassessment to postassessment: student Gender Identity Competency, t(76) = −11.07, p<0.001; skills, t(76) = −15.22, p<0.001; and self-reported knowledge, t(76) = −4.36, p<0.001. Negative attitudes did not differ (p=0.378). Interest in TGNC issues beyond healthcare settings did not change (p=0.334). M2 students reported a significant change in experience role-playing chosen pronouns in a clinical setting, t(76) = −8.95, p<0.001.

Conclusions

The curriculum improved students’ gender-affirming medical competency, knowledge and skills. The development of a sustained, longitudinal curriculum is recommended in addition to the continuing education of faculty to reinforce this expanding knowledge and skills base and to address discomfort working with this population.

Racial differences in posttraumatic stress disorder symptoms among African American and Caucasian male veterans

Objective

Posttraumatic stress disorder (PTSD) is one of the most prevalent mental health diagnoses for veterans. Previous research as well as the minority stress model and transgenerational trauma theories, suggest that race may be associated with PTSD, particularly in veterans. The current study examined whether there were racial differences in symptomology in a sample of combat veterans with PTSD (global and symptom cluster-specific).

Methods

Data were collected from male veterans who identified as non-Hispanic Caucasian or non-Hispanic African American (N = 413). Participants completed the Posttraumatic Stress Disorder Checklist- Military version (PCL-M). The PCL-M items were split into four symptom clusters to align with the DSM-5: Re-experiencing, Avoidance, Numbing, and Hyperarousal. It was hypothesized that African American veterans would report more severe global PTSD symptoms and higher levels of hypervigilance.

Results

Findings indicated global PTSD symptoms and three of the four symptom clusters did not differ, although the symptom cluster of Re-experiencing was found to be higher for African Americans compared to Caucasians.

Conclusions

It may be helpful for researchers to broaden their methods of assessing PTSD symptomology, such as to examine specific PTSD symptom clusters, especially when assessing differences by race.

Many Labs 2: Investigating Variation in Replicability Across Samples and Settings

We conducted preregistered replications of 28 classic and contemporary published findings, with protocols that were peer reviewed in advance, to examine variation in effect magnitudes across samples and settings. Each protocol was administered to approximately half of 125 samples that comprised 15,305 participants from 36 countries and territories. Using the conventional criterion of statistical significance ( p < .05), we found that 15 (54%) of the replications provided evidence of a statistically significant effect in the same direction as the original finding. With a strict significance criterion ( p < .0001), 14 (50%) of the replications still provided such evidence, a reflection of the extremely high-powered design. Seven (25%) of the replications yielded effect sizes larger than the original ones, and 21 (75%) yielded effect sizes smaller than the original ones. The median comparable Cohen’s ds were 0.60 for the original findings and 0.15 for the replications. The effect sizes were small (< 0.20) in 16 of the replications (57%), and 9 effects (32%) were in the direction opposite the direction of the original effect. Across settings, the Q statistic indicated significant heterogeneity in 11 (39%) of the replication effects, and most of those were among the findings with the largest overall effect sizes; only 1 effect that was near zero in the aggregate showed significant heterogeneity according to this measure. Only 1 effect had a tau value greater than .20, an indication of moderate heterogeneity. Eight others had tau values near or slightly above .10, an indication of slight heterogeneity. Moderation tests indicated that very little heterogeneity was attributable to the order in which the tasks were performed or whether the tasks were administered in lab versus online. Exploratory comparisons revealed little heterogeneity between Western, educated, industrialized, rich, and democratic (WEIRD) cultures and less WEIRD cultures (i.e., cultures with relatively high and low WEIRDness scores, respectively). Cumulatively, variability in the observed effect sizes was attributable more to the effect being studied than to the sample or setting in which it was studied.

Examination of Racial Differences in a Posttraumatic Stress Disorder Group Therapy Program for Veterans

Posttraumatic stress disorder (PTSD) is one of the most prevalent mental health diagnoses for veterans. Group therapy can be an effective and efficient means of treating PTSD, yet the literature exploring treatment outcomes for racial minorities is mixed and limited. The present study was an evaluation across racial groups of the PTSD Recovery Program, a manualized group therapy implemented at a Veterans Affairs hospital. Data were collected from male veterans (N = 450) who identified as non-Hispanic White or non-Hispanic African American and participated in a 10-week, combat-related, group therapy program between 2010 and 2014. Participants completed the Posttraumatic Stress Disorder Checklist-Military version (PCL-M) measure at pre-treatment and post-treatment. The Program led to a statistically significant reduction in PCL-M scores (Cohen's d = .64). Symptom reduction occurred regardless of race, with no racial differences in improvement. Racial and ethnic composition of groups was not related to outcomes. The Program was effective regardless of veteran group or provider. Results imply that the PTSD Recovery Program is an effective first-line option to treating non-Hispanic White and non-Hispanic African American veterans with PTSD. Future research should continue to explore the associations between group characteristics and treatment outcomes.

Negative Interpersonal Interactions and Dating Abuse Perpetration: The Mediating Role of Dispositional Forgivingness

Theory and research suggest that an individual's negative interactions with his or her parents or romantic partner are associated with the perpetration of dating abuse. Research is beginning to explore the role of forgivingness within abusive romantic relationships, and these preliminary findings suggest that dispositional forgivingness might mediate the relations between negative interpersonal interactions and dating abuse. The current study assessed negative interactions with one's parents and one's romantic partner, the frequency of dating abuse perpetration, and dispositional forgivingness of others and oneself among a sample of emerging adults in college ( n = 421). Dispositional forgivingness of others was negatively associated with the perpetration of emotional/verbal dating abuse and threatening behaviors, and it mediated relations between negative interpersonal interactions and dating abuse perpetration. Our findings suggest that the tendency to forgive others may explain why some individuals who experience negative interpersonal interactions with parents or romantic partners do not escalate to perpetration of abuse within their romantic relationships. Implications for future research and application are discussed.

Moderation of improvement in self-efficacy following group psychotherapy for PTSD

Posttraumatic stress disorder (PTSD) is a primary mental health concern of veterans. In clinical settings, efforts to improve broad facets beyond symptom amelioration and consideration of moderators of treatment effectiveness in this population are needed for continued improvement in care. General self-efficacy (GSE) has been indicated as a useful treatment target because of its association with positive outcomes such as increased positive health behaviors. Both race and educational attainment represent potential moderators of treatment response that are relevant for a veteran PTSD population. This study aimed to determine whether a PTSD Recovery Group Therapy Program resulted in improvement in GSE and whether racial and educational differences moderated GSE outcomes. Archival data were examined from male veterans (N = 450) receiving mental health services at a Veterans Affairs medical center using multilevel modeling to examine change in GSE over the course of treatment as well as moderation of change in GSE as a function of race and educational attainment. After completion of group therapy, results indicated there was significant improvement in GSE, with significantly different improvement based on education. Higher levels of education were associated with greater increases in GSE after treatment. Improvement in GSE did not differ by participant race. In clinical settings, efforts to increase GSE and attending to moderators such as educational attainment may be useful for improving PTSD treatment approaches.

Effects of Aging on General and Specific Memory for Impressions

Despite the number of documented declines in memory with age, memory for socioemotional information can be preserved into older adulthood. These studies assessed whether memory for character information could be preserved with age, and how the general versus specific nature of the information tested affected outcomes. We hypothesized that memory for general impressions would be preserved with age, but that memory for specific details would be impaired. In two experiments, younger and older adults learned character information about individuals characterized as positive, neutral, or negative. Participants then retrieved general impressions and specific information for each individual. The testing conditions in Experiment 2 discouraged deliberate recall. In Experiment 1, we found that younger performed better than older adults on both general and specific memory measures. Although age differences in memory for specific information persisted in Experiment 2, we found that younger and older adults remembered general impressions to a similar extent when testing conditions encouraged the use of "gut impressions" rather than deliberate retrieval from memory. We conclude that aging affects memory for specific character information, but memory for general impressions can be age-equivalent. Furthermore, there is no evidence for a positivity bias or differences in the effects of valence on memory across the age groups.

Contrast enhanced ultrasound imaging can predict vascular-targeted photodynamic therapy induced tumor necrosis in small animals

AIMS

To evaluate the accuracy of contrast-enhanced ultrasound (CEUS) for monitoring tumor necrosis following WST-11 vascular targeted photodynamic therapy (VTP) using imaging-pathology correlation.

METHODS

Renal adenocarcinoma cells were injected into the hindlimb of 13 BalB/c mice resulting in tumors ranging from 9.8 to 194.3mm³. US guidance was used to place a laser fiber into the tumor, and VTP was performed. CEUS was performed prior to animal sacrifice, 24h post-VTP. Whole tumors were extracted for histopathologic analysis using H&E and TUNEL staining. Pathology samples corresponding to the CEUS imaging plane were prepared in order to compare the size and extents of tumor necrosis.

RESULTS

Tumor necrosis following VTP appeared as a central region of non-enhancement on CEUS, while viable tumor appeared as patchy regions of enhancement in the tumor periphery. The region of tumor necrosis measured in mean 66% and 64.8% of total tumor area on CEUS and pathology respectively (p=0.2). The size and location of the necrosis on CEUS images and pathology samples were found correlative with no inter-observer difference (weighted kappa of 0.771 and 0.823, respectively).

CONCLUSION

CEUS allows accurate monitoring of VTP induced tumor necrosis in a small animal model.

Patient selection for prostate focal therapy in the era of active surveillance: an International Delphi Consensus Project

BACKGROUND

Whole-gland extirpation or irradiation is considered the gold standard for curative oncological treatment for localized prostate cancer, but is often associated with sexual and urinary impairment that adversely affects quality of life. This has led to increased interest in developing therapies with effective cancer control but less morbidity. We aimed to provide details of physician consensus on patient selection for prostate focal therapy (FT) in the era of contemporary prostate cancer management.

METHODS

We undertook a four-stage Delphi consensus project among a panel of 47 international experts in prostate FT. Data on three main domains (role of biopsy/imaging, disease and patient factors) were collected in three iterative rounds of online questionnaires and feedback. Consensus was defined as agreement in ⩾80% of physicians. Finally, an in-person meeting was attended by a core group of 16 experts to review the data and formulate the consensus statement.

RESULTS

Consensus was obtained in 16 of 18 subdomains. Multiparametric magnetic resonance imaging (mpMRI) is a standard imaging tool for patient selection for FT. In the presence of an mpMRI-suspicious lesion, histological confirmation is necessary prior to FT. In addition, systematic biopsy remains necessary to assess mpMRI-negative areas. However, adequate criteria for systematic biopsy remains indeterminate. FT can be recommended in D'Amico low-/intermediate-risk cancer including Gleason 4+3. Gleason 3+4 cancer, where localized, discrete and of favorable size represents the ideal case for FT. Tumor foci <1.5 ml on mpMRI or <20% of the prostate are suitable for FT, or up to 3 ml or 25% if localized to one hemi-gland. Gleason 3+3 at one core 1mm is acceptable in the untreated area. Preservation of sexual function is an important goal, but lack of erectile function should not exclude a patient from FT.

CONCLUSIONS

This consensus provides a contemporary insight into expert opinion of patient selection for FT of clinically localized prostate cancer.

A multi-level modeling approach examining PTSD symptom reduction during prolonged exposure therapy: moderating effects of number of trauma types experienced, having an HIV-related index trauma, and years since HIV diagnosis among HIV-positive adults

People living with HIV (PLWH) have extensive interpersonal trauma histories and higher rates of posttraumatic stress disorder (PTSD) than the general population. Prolonged exposure (PE) therapy is efficacious in reducing PTSD across a variety of trauma samples; however, research has not examined factors that influence how PTSD symptoms change during PE for PLWH. Using multi-level modeling, we examined the potential moderating effect of number of previous trauma types experienced, whether the index trauma was HIV-related or not, and years since HIV diagnosis on PTSD symptom reduction during a 10-session PE protocol in a sample of 51 PLWH. In general, PTSD symptoms decreased linearly throughout the PE sessions. Experiencing more previous types of traumatic events was associated with a slower rate of PTSD symptom change. In addition, LOCF analyses found that participants with a non-HIV-related versus HIV-related index trauma had a slower rate of change for PTSD symptoms over the course of PE. However, analyses of raw data decreased this finding to marginal. Years since HIV diagnosis did not impact PTSD symptom change. These results provide a better understanding of how to tailor PE to individual clients and aid clinicians in approximating the rate of symptom alleviation. Specifically, these findings underscore the importance of accounting for trauma history and index trauma type when implementing a treatment plan for PTSD in PLWH.

Standardization of definitions in focal therapy of prostate cancer: report from a Delphi consensus project

PURPOSE

To reach standardized terminology in focal therapy (FT) for prostate cancer (PCa).

METHODS

A four-stage modified Delphi consensus project was undertaken among a panel of international experts in the field of FT for PCa. Data on terminology in FT was collected from the panel by three rounds of online questionnaires. During a face-to-face meeting on June 21, 2015, attended by 38 experts, all data from the online rounds were reviewed and recommendations for definitions were formulated.

RESULTS

Consensus was attained on 23 of 27 topics; Targeted FT was defined as a lesion-based treatment strategy, treating all identified significant cancer foci; FT was generically defined as an anatomy-based (zonal) treatment strategy. Treatment failure due to the ablative energy inadequately destroying treated tissue is defined as ablation failure. In targeting failure the energy is not adequately applied to the tumor spatially and selection failure occurs when a patient was wrongfully selected for FT. No definition of biochemical recurrence can be recommended based on the current data. Important definitions for outcome measures are potency (minimum IIEF-5 score of 21), incontinence (new need for pads or leakage) and deterioration in urinary function (increase in IPSS >5 points). No agreement on the best quality of life tool was established, but UCLA-EPIC and EORTC-QLQ-30 were most commonly supported by the experts. A complete overview of statements is presented in the text.

CONCLUSION

Focal therapy is an emerging field of PCa therapeutics. Standardization of definitions helps to create comparable research results and facilitate clear communication in clinical practice.

Comparison of mental health between individuals with spinal cord injury and able-bodied controls in Neiva, Colombia

Although research has investigated the mental health of individuals with spinal cord injury (SCI), an overwhelming majority of this research has been conducted in the United States, Western Europe, and other developed countries. The purpose of this study was to compare the mental health of individuals with SCI with able-bodied controls in Neiva, Colombia, South America. Subjects included 40 Colombians with SCI and 42 age- and sex-matched controls (N = 82). The groups did not differ based on age, sex, years of education, or socioeconomic status. However, controls were twice as likely to be married. Four measures assessed mental health, including satisfaction with life (Satisfaction with Life Scale), depressive symptoms (Patient Health Questionnaire-9), self-esteem (Rosenberg Self-Esteem Scale), and anxiety (State-Trait Anxiety Inventory). In comparison with able-bodied controls, individuals with SCI reported significantly lower mental health on both depressive symptoms and satisfaction with life. These effect sizes were medium and large, respectively. The groups did not differ significantly on measures of self-esteem or anxiety. Mental health of individuals with SCI should be considered a central part of SCI rehabilitation interventions, particularly in Latin America.

Age differences in self-referencing: Evidence for common and distinct encoding strategies

Although engagement of medial prefrontal cortex (MPFC) underlies self-referencing of information for younger and older adults, the region has not consistently been implicated across age groups for the encoding of self-referenced information. We sought to determine whether making judgments about others as well as the self influenced findings in the previous study. During an fMRI session, younger and older adults encoded adjectives using only a self-reference task. For items later remembered compared to those later forgotten, both age groups robustly recruited medial prefrontal cortex, indicating common neural regions support encoding across younger and older adults when participants make only self-reference judgments. Focal age differences emerged in regions related to emotional processing and cognitive control, though these differences are more limited than in tasks in which judgments also are made about others. We conclude that making judgments about another person differently affects the ways that younger and older adults make judgments about the self, with results of a follow-up behavioral study supporting this interpretation. This article is part of a Special Issue entitled Memory and Aging.

The relationship between physical and mental health variables in individuals with spinal cord injury from Latin America

BACKGROUND

Previous research has examined the health-related quality of life (HRQOL) and mental health of persons with spinal cord injury (SCI), but the majority of the research has taken place in the United States, Western Europe, and other developed countries. Limited research has been conducted with persons with SCI in Latin America.

OBJECTIVE

To examine the relationship between HRQOL and mental health in persons with SCI from Neiva, Colombia.

DESIGN

Cross-sectional.

SETTING

Participants were recruited from the Foundation for the Integral Development of People with Disabilities, a nonprofit community organization for persons with disabilities.

PARTICIPANTS

Forty persons with SCI from Neiva, Colombia.

METHODS

Caregivers completed the Spanish versions of questionnaires.

MAIN OUTCOME MEASURES

Participants completed self-report measures of HRQOL (SF-36 Health Questionnaire) and mental health (Satisfaction with Life Scale, Patient Health Questionnaire-9, and State Trait Anxiety Inventory).

RESULTS

The hypothesis that higher HRQOL would be related to better mental health found robust support, as the canonical correlation between these 2 sets of variables uncovered that 50.4% of the variance was shared, such that persons with lower HRQOL had reduced mental health. Within this canonical correlation, anxiety, fatigue, and general health loaded most highly, suggesting that persons with SCI who experienced lower energy and reduced general health tended to have high anxiety. Additionally, 9 out of the 18 bivariate correlations between these 2 variable sets were statistically significant.

CONCLUSIONS

In Latin America, SCI rehabilitation services are extremely sparse and rarely include interventions that target postinjury mental health. The current study suggests that mental health issues in patients with reduced HRQOL warrant attention in SCI rehabilitation services, especially in this region.

Quality of life and long-term survival after surgery for chronic pancreatitis

The objective of this study was to evaluate the short-term and long-term outcome as well as quality of life in patients undergoing surgical management of chronic pancreatitis. Between January 1980 and December 1996, a total of 255 patients underwent surgery for chronic pancreatitis at The Johns Hopkins Hospital. The etiology of the disease, indications for surgery, patient characteristics, and long-term survival were analyzed. A visual analog quality-of-life questionnaire containing 23 items graded on a scale of 0 to 10 (0 = worst and 10 = best) was sent to patients postoperatively. Visual analog responses relating to before and after the chronic pancreatitis surgery were compared using a paired t test. During the17-year review period, 263 operations were performed for chronic pancreatitis in 255 patients. The most common presenting symptoms were abdominal pain (88%), weight loss (36%), nausea/vomiting (30%), jaundice (14%), and diarrhea (12%). The cause of the pancreatitis was resumed to be alcohol in 43%, idiopathic in 38%, pancreas divisum in 5%, ampullary abnormality in 4%, and gallstones in 3%. Pancreaticoduodenectomy was the most common procedure in 96 patients (37%), followed by distal pancreatectomy in 67 (25%), Puestow procedure in 52 (19%), sphincteroplasty in 37 (14%), and Duval procedure in five (2%). The overall mortality and morbidity rates were 1.9% and 35%, respectively. Two hundred twenty-seven (89%) of the 255 patients were alive at last follow-up. For the entire cohort of patients, the 5- and 10-year actuarial survivals were 88% and 82%, respectively. One hundred six (47%) of the 227 living patients responded to the visual analog quality-of-life questionnaire. Patients reported improvements in all aspects of the quality-of-life survey including enjoyment out of life, satisfaction with life, pain, number of hospitalizations, feelings of usefulness, and overall health (P < 0.005). In addition to improved quality of life after surgery, narcotic use was decreased (41% vs. 21%, P < 0.01) and alcohol use was decreased (59% vs. 33%, P < 0.001). However, patients often became insulin-dependent diabetics (12% vs. 41%, P < 0.0001) and required pancreatic enzyme supplementation (34% vs. 55%, P < 0.01) after surgical intervention. These data suggest that surgery for patients with chronic pancreatitis can be performed safely with minimal morbidity and excellent long-term survival. Moreover, this study evaluates quality of life in a standardized analog fashion, with highly significant improvement reported in all quality-of-life measures. We conclude that surgery remains an excellent option for patients with chronic pancreatitis.

Laser-assisted uvulopalatoplasty: long-term results with a treatment for snoring

We present a retrospective analysis of the initial results of our institution's evaluation of a new procedure designed to help relieve snoring, as well as having the potential to assist in the treatment of obstructive sleep apnea. The ambulatory, in-office CO2 laser procedure is performed with a local anesthetic. It is a serial procedure that achieves the same end-result as conventional uvulopalatopharyngoplasty, but without many of the associated problems. The indications for the procedure are reviewed, and detailed technical aspects of its performance, including use of new instrumentation, are discussed. Detailed analysis of the first 20 patients to undergo the procedure in the United States is presented. This is the first series of patients presented in the American literature who have undergone this procedure and who have had long-term follow-up of more than five years. A 90% success rate was achieved. The complication rate, patient tolerance, relative costs, indications and contraindications are discussed.

Laser utilization in the oral pharynx

In the past three decades, the surgical laser has evolved into an invaluable tool in the practice of otolaryngology-head and neck surgery with many applications in the treatment of oropharyngeal lesions. The use of lasers has allowed many of these lesions to be treated effectively in the office setting with minimal patient discomfort. These applications are reviewed, and the advantages and shortcomings of laser use in the oropharynx are discussed.

Treatment of nasopharyngeal inlet stenosis following uvulopalatopharyngoplasty with the CO2 laser

This report looks at outpatient treatment of nasopharyngeal inlet stenosis, a more commonly seen postoperative complication of uvulopalatopharyngoplasty (UPPP). It does not study the effectiveness of the UPPP for treatment of obstructive sleep apnea syndrome (OSAS). The authors evaluated six patients who had a UPPP for OSAS, all of whom developed stenosis in the nasopharyngeal inlet ranging from 14 mm to complete closure. Two patients had failed rotation flap repairs. The carbon dioxide laser was used to treat these patients in the office under a local anesthesia in a staged manner. We now have patients from 3 months to 12 months follow-up who have had stenosis treated successfully. We believe that the postoperative complication of nasopharyngeal inlet stenosis after UPPP can be treated in a safe and cost-effective manner in the office setting.

Laser treatment of lower airway stenosis

This article reviews the various laser techniques used in the endoscopic treatment of lower airway stenosis. The tests of lasers and laser settings used are presented along with the various success rates for the particular techniques. Also presented in this article are the criteria for differentiating those patients who are likely to have a good response to endoscopic techniques versus those patients who should have open techniques performed.

Clinical applications of lasers in otolaryngology--head and neck surgery

The use of lasers in otolaryngology--head and neck surgery is described from the invention of the laser in 1960, through the current uses of the laser, and concludes with a summary for the future directions of laser surgery. The various lasers, including the argon, the KTP, and the carbon dioxide lasers used in otolaryngology, are briefly described. The applications of lasers in the larynx, sinuses, and the ear are separately covered, as well as pediatric otolaryngology. In addition to a brief description of the procedure, the complications and limitations are given. Anesthetic considerations are also covered.

Ultrasonic tissue characterization of uveal melanoma and prediction of patient survival after enucleation and brachytherapy

We performed survival studies on 136 patients with uveal malignant melanoma who were examined with ultrasonic tissue characterization before treatment with cobalt-60 brachytherapy (74 patients) or enucleation (62 patients). Mean follow-up time was 58.7 months for the brachytherapy group and 59.0 months for the enucleated group. The maximal follow-up time was nearly ten years. Univariate survival analysis showed that patients with small tumors (less than 250 mm3, 49 patients) had a higher five-year survival when treated with brachytherapy than when treated with enucleation. No patients in this study with tumor volumes greater than 1,500 mm3 (13 patients) were treated with brachytherapy. For tumors of intermediate size (74 patients), survival analysis did not indicate appreciable differences between the treatment options. However, multivariate models including two ultrasonic tissue characterization variables, scatterer size and concentration, showed appreciable intergroup differences in the dependence of survival on these factors. Results suggest that tissue properties detectable with ultrasonic techniques are related to differences in patient survival and may be used for treatment planning for tumors of intermediate size.

Dermatofibrosarcoma protuberans of the head and neck

To elucidate the natural history of dermatofibrosarcoma protuberans of the head and neck, 17 cases were reviewed and compared with 92 others contained within the English literature. The prototypic case is seen as a firm, solitary, slowly enlarging, asymptomatic, cutaneous nodule between 2 and 5 cm in size and of two years' duration. It is more common in men and in persons aged between 30 and 40 years. The scalp and neck-supraclavicular fossa are the most common sites, accounting for half of the cases. Approximately 50% to 75% of the patients experience local recurrence after initial surgery and, of these, half to three fourths manifest within three years of treatment. Metastases, seen in no more than 6% of all cases, are almost invariably preceded by two or more local recurrences and occur primarily through the bloodstream to the lungs and bones and less often to regional lymph nodes.

Perforation of the peptic ulceration in the elderly

A retrospective survey of elderly patients admitted with perforation of a duodenal ulcer showed that some presented with typical symptoms and signs of a perforation, while others presented as a gastro-intestinal bleed or with confusion or malaise. Diagnosis tended to be delayed in the latter group and mortality was higher. Earlier diagnosis may be helped by taking a chest radiograph or lateral decubitus films of the abdomen with a repeat film in a few hours if the diagnosis is still being considered.
