Factors Associated with Delayed Palatoplasty Before, During, and After the COVID-19 Pandemic.

BACKGROUND: Cleft palatoplasty is typically performed around 10 to 12 months of age in the US, and delays can negatively affect speech development. Early during COVID-19, elective surgeries were canceled. The aims of this study were to (1) identify overall risk factors for greater age at palatoplasty and (2) analyze delays in palatoplasty during COVID-19. METHODS: This study was part of a larger prospective, multicenter comparative study of speech outcomes in palatoplasty. Participants underwent palatoplasty between March 2019 and September 2022 at 18 pediatric hospitals in the United States. Ages were corrected for prematurity. Dates of palatoplasty were divided into 4 periods corresponding to different phases of the pandemic. Factors analyzed included region, language, adoption status, sex, ethnicity, race, rurality, health insurance type, and cleft type. Analyses were performed using ANOVA, Student's test, and multivariable linear regression, with a P value of ≤0.05 being significant. RESULTS: Nine hundred twenty-eight participants were included. Average corrected age at palatoplasty was 374 days. In univariable analysis, palatoplasty was performed later in children who were Hispanic (P=0.003), of a race other than White, Black, or Asian (P<0.001), and without private insurance (P<0.001). On multivariable regression, predictors of delayed palatoplasty were Hispanic ethnicity (P=0.015), from other race (P<0.001), and without private insurance (P<0.001). During COVID-19, disproportionate delays occurred in patients who were female, of other races, from nonrural areas, and on Medicaid. CONCLUSIONS: Palatoplasty was performed later in vulnerable populations. Some of these populations were also disproportionately affected by COVID-19 delays. Providers should be aware of these differences as they pertain to equitable access to craniofacial care. LEVEL OF EVIDENCE: III.

Prospective Evaluation of Health-Related Quality-of-Life in Children with Craniosynostosis.

OBJECTIVE: To investigate health-related quality of life (HRQL) in children aged 2 to 7 years, who have undergone surgery for craniosynostosis. DESIGN: Cross-sectional survey. SETTING: A tertiary pediatric academic medical center. PARTICIPANTS: Children with craniosynostosis who underwent surgical correction, and who were 2-7 years old at the time of the study. Children from families that did not speak English were excluded. INTERVENTIONS: Caregivers were asked to fill out the Pediatric Quality of Life Inventory (PedsQL) Core Parent Report and the PedsQL Cognitive Functioning Scale. MAIN OUTCOME MEASURES: PedsQL: Psychosocial Health Summary Score, Physical Health Summary Score, Total Core Score, Cognitive Functioning Scale Score. Scores range from 0 to 100, with higher scores reflecting greater QoLSubject factors: comorbidities, syndromic status, type of craniosynostosis, type of surgery. RESULTS: The study included 53 subjects, of whom 13.2% had a syndrome. Core and cognitive scores did not depend on presence of a syndrome or suture involved. Subjects who underwent posterior cranial distraction achieved higher Total Core Scores than subjects who underwent open vault remodeling. Among subjects with sagittal craniosynostosis, there was a tendency for higher scores among children who underwent minimally-invasive surgery compared to those who underwent open vault remodeling. CONCLUSIONS: This study demonstrates similar HRQL among children with and without a syndrome, higher HRQL among children undergoing posterior cranial distraction than those undergoing open vault remodeling, and trends towards higher HRQL in children with sagittal craniosynostosis who underwent minimally-invasive surgery compared to those who underwent open vault remodeling.

Posterior Cranial Distraction in Craniosynostosis: A Systematic Review of the Literature.

OBJECTIVE: Posterior cranial distraction (PCD) is a surgical technique to address craniosynostosis, especially in syndromic patients. The technique has the ability to significantly expand the cranium, while requiring minimal dural dissection, compared to cranial remodeling. Our goals were to determine the patient characteristics and surgical outcomes of PCD. The two questions that we sought to answer were: 1) What is the average published complication rate and the most common complications of PCD? and 2) How much intracranial volume expansion can one expect with PCD? DESIGN: A PubMed database search of articles on PCD was performed. Case reports and articles with overlapping patients were excluded. A systematic review was performed using the remaining articles. MAIN OUTCOME MEASURES: Patient data were extracted in order to determine the total number of patients, patients with a syndrome, types of syndromes, mean age at surgery, mean distraction distance, mean increase in intracranial volume, and complications. RESULTS: 18 articles representing 325 patients were analyzed. A syndrome was present in 68.6% of patients. The mean age at time of surgery was 22.1 months. Mean distraction amount was 24.7 mm. Mean increase in intracranial volume was 253.2 cm3. The overall complication rate was 32.2%, with the most common complications being surgical-site infection, hardware-related complications and delayed wound healing. CONCLUSIONS: PCD is a powerful technique in the management of syndromic craniosynostosis, although complication rates are significantly higher than traditional remodeling techniques. Future studies should compare the effects of supratorcular and infratorcular osteotomies on intracranial volume, cosmesis and complications.

Airway and Feeding Outcomes in Pierre Robin Sequence: A Comparison of Three Management Strategies.

BACKGROUND: Controversy remains regarding optimal management of Pierre Robin sequence (PRS). The goal of this study was to compare airway and feeding outcomes in infants with PRS who underwent surgical intervention, specifically mandibular distraction osteogenesis (MDO) or tongue-lip adhesion (TLA), or who had conservative management (CM) without surgery. METHODS: All consecutive patients treated for PRS at a pediatric academic medical center, with at least one year follow-up, were included. Patients who underwent tracheostomy as an index procedure were excluded. Patients were divided into those who underwent MDO, TLA or CM. Feeding status and data from initial and follow-up polysomnograms were collected. Comparisons between groups were made using the Kruskal-Wallis test, followed by Mann-Whitney pairwise comparison with a Bonferroni correction, when appropriate. RESULTS: 67 neonates were included. 19 underwent TLA, 29 underwent MDO and 19 underwent CM. The proportions of syndromic patients were similar between groups. Patients undergoing CM had the lowest baseline AHI (9.1), but there were no significant differences between TLA (20.1) and MDO (25.4). At follow-up, the three groups had similar mean AHI (MDO 1.3, TLA 4.2, CM 4.5). A similar proportion of patients achieved AHI 5 or less (TLA 89.5%, MDO 96.6%, CM 84.2%). At one year, there were no significant differences in weight percentiles or in risk of failure-to-thrive between groups. One patient from the TLA group required a tracheostomy. CONCLUSION: The three treatment modalities achieved high airway and feeding success rates. All three modalities should have a place in the armamentarium of the craniofacial surgeon.

Spring Cranioplasty: Incorporation Into Practice.

OBJECTIVE: The aim of this paper is to discuss ways to incorporate spring-assisted cranioplasty into the surgical armamentarium for craniosynostosis. BACKGROUND: Spring-assisted cranioplasty after cranial suturectomy for craniosynostosis was popularized in the literature by Dr Lauritzen in 2008 after reporting the results of the first 100 cases. Since that time, more craniofacial surgeons and neurological surgeons have incorporated this surgical technique for treatment of patients presenting with craniosynostosis. This paper will discuss how the team at Nationwide Children's Hospital has incorporated spring-assisted cranioplasty into the care of patients presenting with sagittal synostosis. METHODS: In this article, the authors review our previous protocol for the treatment of children with sagittal synostosis prior to the introduction of spring cranioplasty. The authors then describe the impetus for incorporating spring-assisted cranioplasty for sagittal synostosis into our practice, and barriers we encountered during this implementation. The authors then discuss their current, comprehensive protocol for treating children with sagittal craniosynostosis. Finally, the authors review the expected and unexpected advantages that our craniofacial program has experienced as they implemented spring-assisted cranioplasty. CONCLUSION: Incorporation of spring-assisted cranioplasty for sagittal synostosis offers an additional minimally invasive technique, which presents great advantages for many families, and is rewarding for both craniofacial and neurological surgeons.

Outcomes in Velopharyngeal Dysfunction Treatment: Comparing Two Approaches for Pharyngeal Flaps.

BACKGROUND: The most common surgical intervention to treat velopharyngeal dysfunction in the US is the posterior pharyngeal flap (PPF). In this retrospective study, the authors compare surgical and speech outcomes across 2 PPF surgical approaches: the palatal split (PS) and fish mouth (FM) techniques. METHODS: An Institutional Review Board approved retrospective chart review was performed for PPF cases performed by a single surgeon between 2008 and 2016. Overall, 40 patients received the PS technique and 47 received the FM technique. Age at surgery, operative length, length of stay (LOS), revisional surgery, and pain medication administration were measured. Speech outcomes were measured based on the Universal Parameters for Reporting Speech Outcomes and included Speech Language Pathologist ratings of hypo- and hypernasality, speech acceptability, and audible nasal emission. Two sample t-tests and multivariable-mixed effects logistic regression were used to analyze the data. RESULTS: Comparing the 2 groups (PS versus FM), there were statistically significant differences among the operative approaches across multiple measures: LOS (32.86 hours versus 26.20 hours, P = 0.01), acetaminophen use (1523.54 mg versus 805.74 mg, P = 0.01), revisional surgery rate (17.5% versus 2.10%, P = 0.02), and degree of postoperative hypernasality (0.61 versus 0.29, P = 0.03). Syndromic patients were more likely to receive the FM technique (PS: 15% versus FM: 29.8%; P = 0.05). The odds ratio for revision surgery with the FM technique was -2.32 (CI: -4.32 to -0.35, P = .04). CONCLUSIONS: In this study, the FM technique offered a shorter LOS, lower revision rate, less acetaminophen administration, and more favorable speech outcomes when compared to the PS technique.

Use of antibiotic impregnated resorbable beads reduces pressure ulcer recurrence: A retrospective analysis.

Recurrence of pressure ulcers remains common. We have employed resorbable antibiotic beads as a therapeutic strategy to deliver high local antibiotic concentrations to the debridement site. Our objective was to determine whether the use of resorbable antibiotic- beads would reduce pressure ulcer recurrence. We reviewed all stage IV pressure ulcers treated with excision, partial ostectomy and flap coverage over 16 years. Baseline patient factors (location of ulcer, presence of osteomyelitis, preoperative prealbumin), surgical factors (type of flap, use of antibiotic beads, bone culture results) and postoperative outcomes (ulcer recurrence at 1 year, dehiscence, seroma, cellulitis) were collected. Outcomes of patients who received antibiotic-impregnated beads were compared to those who did not. Eighty-six patients with 120 stage IV pressure ulcers underwent excision and flap coverage. This included 16 ulcers where antibiotic beads were used and 104 where they were not. The overall ulcer recurrence rate at 12 months was 35.8%. The recurrence rate in the group treated with antibiotic beads was significantly lower than the group without beads (12.5% vs. 39.4%, p = 0.03). Overall, complication rates between the two groups were similar (43.8% vs. 51.9%, p = 0.54). No systemic or local toxicity from antibiotic beads occurred. Scanning electron microscopy images of sacral bone from one case showed bacterial biofilm even after debridement. Pressure ulcer recurrence at 1 year after excision and flap coverage decreased significantly with the use of resorbable antibiotic beads.

Effects of the Affordable Care Act on Payer Mix and Physician Reimbursement in Hand Surgery.

PURPOSE: To evaluate the effect of the Affordable Care Act (ACA) on the payer distribution and reimbursement rate for hand surgery at our institution. METHODS: We reviewed records of 4,257 patients who underwent hand surgery at our institution between January 2008 and June 2016; 2,601 patients underwent surgery before the implementation of the ACA, and 1,656 patients after. Type of procedure, insurance status, amount of money billed, and amount collected were recorded. RESULTS: After the implementation of the ACA, we performed fewer metacarpal fracture repairs, distal radius fracture repairs, and abscess incision and drainage procedures. We performed more endoscopic carpal tunnel releases. The proportion of uninsured patients decreased significantly (15% to 6.4%), and the proportion of patients on Medicare (15.4% to 20.3%) and Medicaid (9.5% to 17.8%) increased significantly. The overall reimbursement rate did not change significantly (32.3% to 30.3%) between the 2 time periods. CONCLUSIONS: After the implementation of the ACA, we observed a significant reduction in the number of uninsured patients and an increase in Medicaid and Medicare patients. However, this led to no significant change in reimbursement rates. TYPE OF STUDY/LEVEL OF EVIDENCE: Economic and design analysis II.

Patient Satisfaction After Rhinoplasty: A Social Media Analysis.

BACKGROUND: Compared to other cosmetic procedures, rhinoplasty has a relatively low patient satisfaction rate, due to the difficulty of the procedure, and potentially unrealistic patient expectations. Understanding the reasons behind patient dissatisfaction is key to improving outcomes. Previous authors have done surgeon-initiated surveys, expert ratings, and morphologic measurements, to measure rhinoplasty success. No study has analyzed online reviews by patients to identify reasons for dissatisfaction with rhinoplasty. OBJECTIVES: The goal of this study was to analyze satisfaction patterns in rhinoplasty using online reviews. METHODS: All primary rhinoplasty reviews on RealSelf (Seattle, WA), a social media website for patients undergoing cosmetic surgery, were reviewed. The researchers recorded patient gender, whether they were satisfied, and the reasons for satisfaction or dissatisfaction. Male and female patients were compared, using chi-squared analysis. RESULTS: There were 2326 reviews for primary rhinoplasty (2032 females, 294 males). The overall satisfaction rate was 83.6%. Significantly more females than males were satisfied (87.6% vs 56.1%, P < .001). Among males, the most common reasons for dissatisfaction were residual dorsal hump, under-rotated tip, and a nose that was too small. Among females, the most common reasons for dissatisfaction were residual dorsal hump, under-rotated tip, and bulbous tip. Among dissatisfied patients, females were significantly more likely than males to precisely verbalize the morphologic or functional reason for their dissatisfaction. CONCLUSIONS: We found that males had lower satisfaction with rhinoplasty, and were more vague when expressing reasons for dissatisfaction, than females. Social media provides a novel way to understand reasons for patient dissatisfaction after cosmetic surgery.

Processes of Care in Breast Reconstruction and the Long-Term Impact of a Comprehensive Breast Center.

BACKGROUND: Increased emphasis has been placed on process outcomes for breast cancer care, but limited data exists on these measures for breast reconstruction. These processes are likely to be impacted by increased centralization of care into comprehensive breast centers (CBC). Our study objectives were to define measures for processes of care in breast reconstruction and to determine the effect of a CBC on these measures. METHODS: A 5-year review was performed of patients who underwent mastectomy with or without reconstruction for a newly diagnosed breast cancer between 2010 and 2014, which spans from 1 year before to 4 years after introduction of our CBC. RESULTS: A total of 4179 patients were reviewed. The referral rate for immediate reconstruction increased from 40.0 to 70.8 % (p < .001), and the immediate reconstruction rate increased from 36.7 to 65.0 % (p < .001), both plateauing in the fourth study year. The interval between surgical oncology and plastic surgery consultation decreased (from 9.2 to 2.5 days; p < .001), and stabilized in the second study year. The interval between plastic surgery consultation and surgery decreased throughout the entire study period (from 37.6 to 20.8 days; p < .001), resulting in continued improvements in the interval between surgical oncology consultation and surgery (from 46.8 to 23.3 days, p < .001). CONCLUSIONS: In breast reconstruction, a CBC results in improvements in process outcomes, some of which are realized in the short-term and others in the long-term. The timeliness of treatment of patients who undergo immediate postmastectomy reconstruction can be similar to targets set for patients who undergo mastectomy alone.

Modern reconstructive techniques for abdominal wall defects after oncologic resection.

Resection of abdominal wall tumors often leaves patients with debilitating soft tissue defects. Modern reconstructive techniques can be used to restore abdominal wall integrity. In this article, we present an overview of preoperative patient evaluation, analysis of the defect, surgical planning, and the spectrum of available surgical techniques, ranging from simple to complex. The established clinical evidence in the field of abdominal wall reconstruction is summarized and a case example is provided.

Analysis of factors contributing to severity of breast cancer-related lymphedema.

BACKGROUND: Upper extremity lymphedema is a well-described complication of breast cancer treatment. Risk factors for lymphedema development include axillary lymph node dissection (ALND), obesity, increasing age, radiation, and postoperative complications. In this study, we seek to evaluate a cohort of patients who have either self-referred or been referred to the Department of Physical Therapy for lymphedema treatment. Our goal is to evaluate specific risk factors associated with the severity of lymphedema in this patient population. METHODS: All patients who presented to the Wexner Medical Center at the Ohio State University between January 1, 2009, and December 31, 2010, with a chief complaint of upper extremity lymphedema after breast cancer treatment were reviewed retrospectively. Upper extremity lymphedema index (UELI) was used as a severity indicator and patient factors including demographics and breast cancer treatments were evaluated. Univariate and multivariate statistical analyses were performed. RESULTS: Fifty (4.5%) patients presented for upper extremity lymphedema treatment after breast cancer treatment (total of 1106 patients treated surgically for breast cancer). Greater UELIs were found in patients 50 years and older, those with ALND, radiation, chemotherapy, pathologic stage greater than 3, and an International Society of Lymphology lymphedema stage II (P < 0.05). The multivariate model showed age older than 50 years and pathologic stage greater than 3 were significant predictors of higher UELI (P < 0.05). CONCLUSIONS: In this study, we report that in patients who present for lymphedema treatment, increased UELI is significantly related to ALND, radiation therapy, chemotherapy, age, and pathologic stage. An improved understanding of the patient population referred for lymphedema treatment will allow for the identification of patients who may be candidates for therapeutic intervention.

Aesthetic outcomes in women undergoing breast-conserving therapy followed by mastectomy and microsurgical reconstruction.

BACKGROUND: In women with early-stage breast cancer, breast-conserving therapy (BCT) provides comparable survival to mastectomy. BCT has the advantage of preserving most of the breast, its skin envelope and the nipple-areola complex. However, deformity may result from the excision of significant amounts of breast tissue, as well as radiation therapy. Several studies have compared patients who underwent BCT to different patients who underwent mastectomy and reconstruction, and found superior aesthetic outcomes in the latter group. Our goal in this study was to compare the aesthetic outcomes in the same women who underwent BCT followed by mastectomy and reconstruction. METHODS: Between 2007 and 2012, 42 women with a history of BCT developed cancer recurrence and underwent mastectomy and microsurgical breast reconstruction at our institution. Photographs before and after mastectomy and reconstruction were rated by a panel of nine judges (two independent plastic surgeons, three surgical oncologists, one radiation oncologist, one medical oncologist, and two medical students), using a validated scale RESULTS: Overall, patients received a significantly higher aesthetic score after mastectomy and reconstruction than after BCT. The greatest areas of aesthetic improvement were breast volume, contour, and projection. Patients whose lumpectomy was in the lower inner quadrant, those undergoing bilateral mastectomy and reconstruction and those completing all stages of their reconstruction had the greatest aesthetic improvement CONCLUSIONS: When advising patients with early-stage breast cancer, the superior aesthetic outcome of mastectomy and microsurgical reconstruction compared to BCT must be weighed against disadvantages such as loss of sensation, length of surgery, and donor-site morbidity.

Maximizing Technological Resources in Plastic Surgery Resident Education.

Modern plastic surgery resident education demands the acquisition of an ever-increasing fund of knowledge and familiarity with more surgical techniques than ever before. This all must take place within the context and boundaries of Accreditation Council for Graduate Medical Education-mandated restrictions on work hours as well as balance of education and service. Technological resources have been developed and can be used to complement the skills that residents acquire while performing their day-to-day activities such as taking care of patients, reading textbooks and journal articles, and assisting or performing surgical procedures. Those complementary resources provide the benefits of portability and accessibility, and can thus be conveniently incorporated into the hectic daily life of a resident. This article presents a summary of the most commonly used currently available advanced technologies in plastic surgery resident education, and suggestions for integration of those technologies into a curriculum.

Timing of prophylactic hysterectomy-oophorectomy, mastectomy, and microsurgical breast reconstruction in BRCA1 and BRCA2 carriers.

BACKGROUND: BRCA (breast cancer susceptibility gene) carriers are at high risk for breast and ovarian malignancies, and often undergo prophylactic total abdominal hysterectomy-bilateral salpingo-oophorectomy (TAH-BSO), bilateral mastectomy, and microsurgical breast reconstruction. Our goal was to determine whether abdominal wall complications and flap choice are affected by the order of those procedures. METHODS: All BRCA carriers who underwent microsurgical breast reconstruction between 2007 and 2012 were studied. Abdominal wall complications and changes in the reconstructive plan were analyzed depending on the order of breast reconstruction and TAH-BSO. RESULTS: 442 patients underwent 612 microsurgical breast reconstructions, 47 of whom were BRCA carriers. TAH-BSO was not a predictor of requiring mesh for fascial closure (OR 1.1, P = 0.8), or of hernia/bulge (OR = 1.6, P = 0.65). In five patients, a DIEP flap was altered to another flap as a direct result of prior TAH-BSO. Robotic TAH-BSO after breast reconstruction took longer to perform than before breast reconstruction (4.48 ± 1.00 hours vs. 3.23 ± 0.70 hours, respectively, P = 0.023), due to abdominal wall tightness. However, none were converted to open. Full-muscle free TRAM flaps (compared to other flaps) and bilateral reconstructions (compared to unilateral) were the only predictors of mesh (OR = 9.85, P < 0.001 and 4.01, P < 0.001), and hernia/bulge (OR = 6.18, P < 0.001 and 2.13, P = 0.07). The order of TAH-BSO and breast reconstruction did not affect complications. CONCLUSIONS: In BRCA carriers, the order of TAH-BSO and microsurgical breast reconstruction does not affect complication rates. However, prior TAH-BSO may make DIEP flaps unfeasible, and robotic TAH-BSO after breast reconstruction takes longer, but can still be performed safely.

A systematic approach to emergent breast free flap takeback: Clinical outcomes, algorithm, and review of the literature.

BACKGROUND: Few evidence-based and detailed algorithms exist on the management of failing breast free flaps, including use of the numerous salvage tools that are available. The purpose of this study was to analyze our outcomes with an algorithmic approach to breast free flap salvage after vascular compromise. A review of the literature is also presented. METHODS: A retrospective review of all breast free flaps performed at our institution between 2007 and 2012 was performed. Flaps with intraoperative and postoperative vascular complications were analyzed. RESULTS: A total of 612 microsurgical breast reconstructions in 442 patients were reviewed. Of these, 72 (11.8%) flaps had intraoperative vascular complications, and 36 (5.9%) had postoperative vascular complications. The total flap loss rate was 2.8%. The most commonly used salvage modalities were anastomotic revision (72%), heparin irrigation (72%), systemic heparin (37%), Fogarty catheter thrombectomy (17.6%), thrombolytics (13%), and indocyanine green angiography (10.2%). In 53 (49.1%) cases, flap salvage involved use of 1 modality, whereas in 55 (50.9%) cases multiple modalities were used. Factors associated with failure of these flap salvage tools included intraoperative arterial rather than postoperative arterial compromise (P = 0.01), and situations requiring use of a greater number of salvage modalities (P < 0.001). CONCLUSIONS: We found that intraoperative compromise had significantly better prognosis than postoperative compromise. By organizing the numerous salvage modalities available to microsurgeons into a well-defined algorithm that is supported by the literature, we have established a best practices protocol that has achieved flap salvage rates that compare favorably to the published literature.

Abdominal Wall Reconstruction with Retrorectus Self-Adhering Mesh: A Single-Center Long-Term Follow-Up.

BACKGROUND: Mesh repair has been demonstrated to be superior to suture alone in ventral hernia repair. In a previous short-term pilot study, the authors found lower postoperative narcotic requirements with self-adhering mesh. The aim of this study was to follow-up on that pilot study, using long-term data. METHODS: This is a retrospective review of a prospectively collected database. All patients who underwent ventral hernia repair with retrorectus mesh and who had at least a 12-month follow-up were reviewed. Comparisons were performed between patients who received self-adhering mesh and those who received transfascially sutured mesh, using matched-pair analysis, examining perioperative outcomes, surgical-site occurrences, and hernia recurrence/bulge. RESULTS: Forty-two patients were included in the study, with 21 patients undergoing repair with transfascially sutured mesh and 21 patients receiving self-adhering mesh. Average length of follow-up was 1078 days. There were no significant differences between the two groups in baseline characteristics. Patients receiving self-adhering mesh had significantly shorter surgery, and a shorter hospital length of stay. They also had a tendency toward lower narcotic requirements. There were no significant differences in the rate of surgical-site occurrences, hernia recurrences, or bulge between the two groups. CONCLUSIONS: This long-term study shows that self-adhering mesh in ventral hernia repair results in similar long-term outcomes to transfascially sutured mesh, with shorter surgery, shorter length of stay, and a tendency toward improved pain control. These findings mirror the known advantages of self-adhering mesh in inguinal hernia repair. Further research is needed to study the incidence of chronic pain and the cost-effectiveness of self-adhering mesh. CLINICAL QUESTION/LEVEL OF EVIDENCE: Therapeutic, III.
