Bilateral Singapore fasciocutaneous flap after anterior vulvectomy and distal urethrectomy for localized recurrent vulvar carcinoma.

Introduction: Vulvar cancer has an overall low incidence, accounting for approximately 3-5% of all gynecological malignancies.Case: We present a case of locally recurrent Stage IIIA squamous cell carcinoma of the vulva in a 51-year-old healthy African American female. She was initially treated with primary chemoradiation with cisplatin sensitization and boost to primary tumor up to 70 Gray. Post-treatment biopsies revealed complete pathologic response. She later presented with local recurrence to the primary site of the clitoris and vulva, with no evidence of metastasis on imaging, with progressive disease despite treatment with immunotherapy. Methods: Biopsy-proven disease progression was present on the clitoris, entire left labia minora, and a portion of the right labia minora with no evidence of metastasis on imaging. Surgical resection for localized recurrence was recommended, and she underwent radical anterior vulvectomy, distal urethrectomy, and vulvar reconstruction with bilateral Singapore fasciocutaneous flap as part of a multidisciplinary team. Patient underwent several prophylactic hyperbaric oxygen treatments. There were no issues with postoperative wound healing. Conclusion: Treatment with radical excision often requires multidisciplinary teams for complex reconstructions to restore vulvar anatomy in the setting of prior radiation, especially for those patients desiring the ability to have penetrative intercourse in the future. There are few surgical videos that describe these types of vulvar excisions and subsequent reconstructions. This video provides a unique approach to vulvar reconstruction in a previously irradiated field.

Racial disparity in excess mortality in Brazil during COVID-19 times.

We evaluated the impact of the COVID-19 pandemic on excess mortality by race/skin colour in Brazil, between epidemiological weeks 12 and 50 of 2020. We compared the 2020 point estimate and the expected point estimate applying 2019 mortality rates to the 2020 population. There was an excess of 187 002 deaths (+20.2%) compared to the expected. Excess mortality was 26.3% (23.3-29.3%) among blacks/browns compared to 15.1% (14.1-16.1%) among whites (58.9% of excess among black/browns). Age-standardized rates increased from 377 to 419/100 000 among blacks/browns compared to 328 to 398/100 000 in whites, resulting in 9% relative risk. Excess mortality in Brazil depicts a considerable gap, with increased mortality in all age groups in the black/brown population.

Safely achieving single prolonged breath-holds of > 5 minutes for radiotherapy in the prone, front crawl position.

OBJECTIVE: Breast cancer radiotherapy is increasingly delivered supine with multiple, short breath-holds. There may be heart and lung sparing advantages for locoregional breast cancer of both prone treatment and in a single breath-hold. We test here whether single prolonged breath-holds are possible in the prone, front crawl position. METHODS: 19 healthy volunteers were trained to deliver supine, single prolonged breath-holds with pre-oxygenation and hypocapnia. We tested whether all could achieve the same durations in the prone, front crawl position. RESULTS: 19 healthy volunteers achieved supine, single prolonged breath-holds for mean of 6.2 ± 0.3 min. All were able to hold safely for the same duration while prone (6.1 ± 0.2 min ns. by paired ANOVA). With prone, the increased weight on the chest did not impede chest inflation, nor the ability to hold air in the chest. Thus, the rate of chest deflation (mean anteroposterior deflation movement of three craniocaudally arranged surface markers on the spinal cord) was the same (1.2 ± 0.2, 2.0 ± 0.4 and 1.2 ± 0.4 mm/min) as found previously during supine prolonged breath-holds. No leakage of carbon dioxide or air was detectable into the facemask. CONCLUSION: Single prolonged (>5 min) breath-holds are equally possible in the prone, front crawl position. ADVANCES IN KNOWLEDGE: Prolonged breath-holds in the front crawl position are possible and have the same durations as in the supine position. Such training would therefore be feasible for some patients with breast cancer requiring loco-regional irradiation. It would have obvious advantages for hypofractionation.

Understanding and Parenting Children's Noncompliant Behavior: The Efficacy of an Online Training Workshop for Resource Parents.

The current study examined the effectiveness of an online training program on parenting children's noncompliant behavior. Eighty-two resource parents (foster, adoptive, and kinship) were recruited through Foster Parent College-an online training website-and randomly assigned to a treatment or wait-list control group. Parents in the treatment group participated in an online interactive workshop on noncompliant child behavior. Online assessments occurred before and after a 1-week intervention, and again 3 months later. Group differences at posttest were significant for parents' reports of children's positive behavior and parent knowledge related to children's noncompliant behavior. Only parents in the treatment group showed significant improvement from pre- to posttest on several other outcome measures of parenting noncompliant behavior. Satisfaction with the online workshop at posttest was very high. Results at the 3-month follow-up assessment showed significant group differences only for parents' knowledge about children's noncompliant behavior. Feedback on the workshop remained positive, with treatment group parents indicating that they felt the workshop had beneficially impacted their parenting and their children's behavior.

Efficacy of Blended Preservice Training for Resource Parents.

To evaluate a new way of meeting the growing demand for training prospective resource parents, our study compared the efficacy of a blended online and in-person approach with a traditional classroom-only approach. Findings based on a sample of 111 resource parent prospects showed significantly greater gains in knowledge from pre- to posttest for the blended approach over the classroom-only approach. The blended approach also produced dramatically lower dropout rates during preservice training. Both groups made significant gains in parenting awareness from pre to post, but those gains were greater for the classroom-only approach. Post hoc analyses examined this finding more closely. Satisfaction with training was comparably high for both groups. Gains in knowledge and awareness were sustained at a 3-month follow-up assessment.

Web-Enhanced Preservice Training for Prospective Resource Parents: A Randomized Trial of Effectiveness and User Satisfaction.

Traditionally, prospective resource parents must attend all preservice training in person. While live sessions are necessary for activities such as screening applicants, instructional portions of training could be enhanced by web-based sessions. This pilot study compares the effectiveness of online and classroom versions of one session from a widely used preservice training program. Ninety-two individuals who volunteered to complete the program in two states were randomly assigned to a treatment group that viewed an online version of the class on child abuse and neglect or a comparison group that took the same class in person. Written questionnaires were completed before and after the class. Significant group differences on knowledge of child maltreatment and empathy toward birth parents, plus high user satisfaction, were hypothesized. ANCOVA results showed the online training was more effective than the live training at increasing knowledge. MANCOVA findings on empathy were not significant but trended toward greater empathy for the online group. Feedback indicated high satisfaction with the online course. If supported by future research, the finding that online instruction is more effective than live has positive implications for practice, because web-based training offers advantages like standardizing instruction, cutting agency and trainee costs, and providing greater flexibility.

Effects of combination dobutamine and vasopressin therapy on microcirculatory blood flow in a porcine model of severe endotoxic shock.

BACKGROUND: Dobutamine (DB) has been recommended in combination with vasopressor therapy in septic shock, given its reported ability to improve mesenteric and microcirculatory perfusion. Vasopressin (VP) is typically reserved as a second-line agent due to the concern of ischemia. The purpose of our study was to determine whether combination DB and VP therapy improved microcirculatory blood flow in severe endotoxic shock. METHODS: Septic shock was induced in 20 anesthetized piglets with injection of E. coli endotoxin. DB (10 µg/kg/min, n = 5) and VP (0.04 units/min, n = 10) were administered alone and in combination (n = 15). Measurements were compared at baseline, following endotoxin administration, and following treatment. Microcirculatory blood flow was determined via the injection of colored microspheres. RESULTS: VP completely reversed endotoxin-mediated hypotension with a mean arterial pressure (MAP) of 85 ± 4.5 mm Hg, which was not significantly altered with the addition of DB (77 ± 4.9 mm Hg). Endotoxin uniformly depressed cardiac output (CO) from baseline (227 ± 10.7 versus 174 ± 12.4 mL/min/kg) despite treatment with VP alone or in combination with DB. The addition of DB did not improve the CO in this severe septic shock model. VP was found to shunt microcirculatory flow from the skin and GI tract to vital organs such as the brain, liver, and kidneys, which was not altered with the addition of DB. CONCLUSIONS: Results indicate that DB is ineffective in increasing CO or improving mesenteric blood flow when used with physiologic replacement doses of VP. In combination, DB is unable to overcome the blood flow distribution achieved with VP administration alone in severe endotoxic shock.

Experience with free TRAM breast reconstruction at an American Army Medical Center.

There are many civilian reports on the outcomes of the free transverse rectus abdominis muscle (TRAM) flap for breast reconstruction. There are no published reports by U.S. military surgeons with this technique. The records of patients undergoing this operation from November 2002 to December 2004 at an Army Medical Center were reviewed. Twenty-one women underwent 27 free TRAM flaps during the study period. No flaps were lost. Significant complications were encountered in 47.6% (10/21) of patients. Seven of these 10 patients had surgery for donor site scar revision. Although technically demanding and time consuming, free TRAM breast reconstruction provides an esthetic result. Free tissue breast reconstruction can be successfully performed with minimal morbidity at U.S. Army Hospitals.

Operation Iraqi freedom: A report on a series of soldiers treated with free tissue transfer by a plastic surgery service.

Free flaps in combat wounds are predisposed to failure. Few reports are available on their use in American military combat wounds. We present our experience with free flaps during Operation Iraqi Freedom. This is a retrospective review of soldiers treated by plastic surgeons at Brooke Army Medical Center. Eight free flaps were for soft tissue coverage in which local tissue was not available. Causes of the wounds: 2 from a rocket-propelled grenade, 4 from explosive devices, 1 from a fall, and 1 from a helicopter crash. Indications for the flaps were 2 exposed calvaria, 3 lower-extremity fractures, 2 upper-extremity wounds, and 1 exposed Achilles tendon. Four latissimus dorsi muscle flaps and 4 radial forearm fasciocutaneous flaps were used. All flaps were successful. Three flap-related complications required operative intervention. Free flaps can be used successfully in combat wounds, with minimal morbidity, and should be considered in American soldiers with complex wounds.

Neuropsychological screening for cognitive impairment using computer-assisted tasks.

The aim of this study was to validate a computer-assisted screening battery for classifying patients into two groups, those with and without cognitive impairment. Participants were all patients referred to the neuropsychology clinics at four VA medical centers during a 1-year period. Patients meeting the study inclusionary criteria (N = 252) were administered the Neurobehavioral Evaluation System-3 (NES3) computer-assisted battery. A detailed neuropsychological examination was carried out by an experienced neuropsychologist, who diagnosed the patient as cognitively impaired or not impaired. The neuropsychologist's diagnosis was the gold standard. Recursive partitioning analyses yielded several classification procedures using the NES3 data to predict the gold standard These procedures produced a set of six NES3 tasks that provide good sensitivity and specificity in predicting di- agnosis. Sensitivity and specificity for the least random classification procedure were 0.87 and 0.67, respectively. The results suggest that computer-assisted screening methods are a promising means of triaging patients.

Interrater reliability of neuropsychological diagnoses: a Department of Veterans Affairs cooperative study.

This study examined the interrater reliability of neuropsychological diagnoses produced by clinical neuropsychologists across 4 medical centers. These diagnoses were based on evaluations using a comprehensive battery of commonly used neuropsychological test instruments, interview, history and medical chart review. The diagnoses of individual neuropsychologists were compared to those made by members of an external review panel for each patient evaluated. Patients were first diagnosed as showing cognitive impairment versus no cognitive impairment. If a patient was diagnosed as impaired, a specific neuropsychological diagnosis was assigned. The diagnostic classification for cognitive impairment was moderately reliable [kappa = .48 +/- s.e.(kappa) = .062]. The interrater reliability for specific diagnoses was in the fair to good range [kappa = .44 +/- s.e.(kappa) = .029]. These levels of reliability are comparable to those found for other psychiatric and neurologic specialties and for medical diagnoses made by other health care disciplines.

Mortality associated with the quality of care of patients hospitalized with congestive heart failure.

OBJECTIVE: This study examined the association between use of angiotensin converting enzyme inhibitors (ACEIs) and risk of death in elderly patients hospitalized with left ventricular systolic dysfunction (LVSD). DESIGN: Retrospective cohort study. SETTING: Despite evidence showing the benefit of treating LVSD with ACEI, elderly patients with LVSD are often not treated with an ACEI. Concern that the risk of ACEI treatment might exceed the benefits in elderly patients is a possible reason. STUDY PARTICIPANTS: We abstracted records from 2943 Medicare beneficiaries hospitalized for congestive heart failure in 69 hospitals in five states. The presence of LVSD was determined from recorded ejection fractions or a narrative description of ventricular function. Discharge medications and dosages were abstracted. MAIN OUTCOME MEASURES: Mortality was tracked for one year using Health Care Finance Administration MEDPRO files. RESULTS: There were 621 patients aged 65 years or older with LVSD. The mean age (SD) was 77.4 years (7.0). At discharge 79% were prescribed an ACEI and, of these, 47% were discharged at the dose recommended by clinical practice guidelines. There were 195 deaths (31.4%) during the year of follow-up. Compared with patients discharged at a recommended ACEI dose, patients not prescribed an ACEI at discharge had an adjusted hazard ratio for death (95% CI) of 1.63 (1.02, 2.60) and patients prescribed an ACEI at a less than recommended dose had a hazard ratio of 1.30 (0.86, 1.97). CONCLUSIONS: Our results show that ACEI use at discharge in elderly patients with LVSD is associated with decreased risk of death.
