RESUMO

BACKGROUND: Volatile and intravenous anesthetics have substantial effects on physiological functions, notably influencing neurological function and susceptibility to injury. Despite the importance of the anesthetic approach, data on its relative risks or benefits during surgical clipping or endovascular treatments for unruptured intracranial aneurysms (UIAs) remains scant. We investigated whether using volatile anesthetics alone or in combination with propofol infusion yields superior neurological outcomes following UIA obliteration. METHODS: We retrospectively reviewed 1001 patients who underwent open or endovascular treatment for UIA, of whom 596 had short- and long-term neurological outcome data (modified Rankin Scale) recorded. Multivariable ordinal regression analysis was performed to examine the association between the anesthetic approach and outcomes. RESULTS: Of 1001 patients, 765 received volatile anesthetics alone, while 236 received propofol infusion and volatile anesthetics (combined anesthetic group). Short-term neurological outcome data were available for 619 patients and long-term data for 596. No significant correlation was found between the anesthetic approach and neurologic outcomes, irrespective of the type of procedure (open craniotomy or endovascular treatment). The combined anesthetic group had a higher rate of ICU admission (p < 0.001) and longer ICU and hospital length of stay (LOS, p < 0.001). Similarly, a subgroup analysis revealed longer ICU and hospital LOS (p < 0.0001 and p < 0.001, respectively) in patients who underwent endovascular UIA obliteration under a combined anesthetic approach (n = 678). CONCLUSIONS: The addition of propofol to volatile anesthetics during UIA obliteration does not provide short- or long-term benefits to neurologic outcomes. Compared to volatile anesthetics alone, the combination of propofol and volatile anesthetics may be associated with an increased rate of ICU admission, as well as longer ICU and hospital LOS.

RESUMO

Studies have linked bibliometric indices with the academic level of plastic surgeons, but this relationship has not been explored with residency program directors (PDs). As teachers of the next generation, PDs' academic performance is an important component of residency program success. We sought to identify distinguishing characteristics of integrated plastic surgery programs, focusing on their PD bibliometric indices. Methods: We identified plastic surgery programs based on 2021 Doximity reputation and research output rankings, respectively, and then divided them into four quartiles (Q1-Q4). PD academic history and bibliometric indices (h-index, the number of publications, and citations) were collected through Doximity profiles and program websites: PubMed, Scopus, Google Scholar, American Society of Plastic Surgeons, and Accreditation Council for Graduate Medical Education. Results: Eighty-four programs were identified. There was a significant positive relationship between h-index, the number of publications, and type of research with reputation ranking (P < 0.05). After adjusting for years of experience post-training, h-index (OR = 1.24; P < 0.001) and the number of publications (OR = 1.05, P < 0.001) were significantly associated with reputation ranking. There was a statistically significant relationship between PD research fellowship completion and research output ranking (P < 0.01). After adjusting for years of experience post-training, h-index (OR = 1.05; P = 0.047) and the number of publications (OR = 1.01; P = 0.04) were significantly associated with research output ranking. Conclusion: Higher ranked programs tend to have PDs who have a strong record of scholarly activity, as evidenced by certain bibliometric indices.

RESUMO

BACKGROUND: Plastic surgery is a competitive specialty that values research productivity among members of the field. The Hirsch index has been shown to measure a researcher's scientific impact. This study sought to determine whether an association exists between H-indices and the probability of and speed to publication. METHODS: Using Scopus, Google Scholar, PubMed, and the Plastic Surgery the Meeting (PSTM) website, first author (FAHi) and senior author (SAHi) H-indices (n = 1048) from Plastic Surgery the Meeting (PSTM) abstracts from 2014 to 2017 were collected. Whether or not an abstract was ultimately published in a peer-reviewed journal was noted. If published, number of days between PSTM presentation and publication date were recorded. Logistic regression model was used for statistical analysis. RESULTS: In total, 592 out of 1048 total abstracts were published as manuscripts. FAHi and SAHi had significant positive correlations with odds of publication. Both FAHi and SAHi showed positive correlation with the odds of abstract publication (P < 0.001 and P = 0.033). Impact of FAHi on likelihood of publication was greater than that of SAHi. The correlation between FAHi and SAHi with the number of days until abstract publication was not significant (P = 0.333 and P = 0.856). For abstracts published before the PSTM presentation date (15.9% of published), only FAHi (P = 0.008) showed positive correlation of publication before presentation. CONCLUSIONS: The Hirsch index provides an objective method for evaluating the probability that an abstract will lead to manuscript publication, in addition to its traditional application in gauging the impact of research. The findings of this study support that both FAHi and SAHi have a positive, direct correlation with the probability of publication.

RESUMO

BACKGROUND: Among elderly orthopedic trauma patients, the prevalence of delirium during hospitalization has been reported to be as high as 60%. Frail elderly patients have an increased risk of delirium after elective surgery; however, such an association remains underexplored among trauma patients. AIM: Our goal was to investigate whether preoperative frailty is associated with postoperative delirium (POD) in elderly orthopedic trauma patients. METHODS: We conducted a single-center, retrospective, cross-sectional study. All patients were ≥ 65 years of age and were admitted to the hospital between 01/01/2017 and 08/31/2018 for surgical intervention of a significant extremity fracture. Frailty was assessed using the fatigue, resistance, ambulation, illness, and loss of weight questionnaire. Delirium was assessed using the Confusion Assessment Method. POD was defined as new-onset delirium that occurred within 24 h after surgery. To investigate whether frailty is associated with POD, we performed a multiple variable logistic regression, controlling for biologically relevant confounders. RESULTS: Five hundred fifty-six patients comprised the analytic cohort. Incidence of POD was 14% (n = 80). Multiple variable regression analysis demonstrated that each unit increment in FRAIL score was associated with a 33% higher likelihood of POD (OR 1.33; 95% CI 1.02-1.72, p = 0.03). CONCLUSIONS: Our results suggest that preoperative frailty increases the risk of POD in hospitalized, elderly, orthopedic trauma patients. Future studies are needed to determine whether perioperative interventions focused on improving frailty can reduce the risk of POD and improve outcomes in this rapidly growing cohort of patients.

RESUMO

ABSTRACT: Velopharyngeal dysfunction (VPD) is described as the incomplete closure of the velopharyngeal port during a speech production. Nasopharyngoscopy and/or multiplanar videofluoroscopy have been utilized for decades to assess the degree and nature of the dysfunction. Cone-beam computed tomography (CBCT) is presented as an additional diagnostic tool, allowing for clear visualization of the affected structures and the ability to obtain accurate measurements (within 100 microns) of the involved anatomy and defect. This prospective pilot study aims to test the feasibility of using "active-phonation" CBCT to assess suspected VPD in the pediatric and young adult populations and compare the results to nasopharyngoscopy; the current standards of care.Six patients, ages 6 to 26 years, with suspected VPD, defined as the inability to completely close off the nasal airway during an oral speech, seen at an urban medical outpatient craniofacial care center, served as subjects for this pilot study. Each patient received a comprehensive speech evaluation and participated in both active-phonation CBCT and nasopharyngoscopy.Both active-phonation CBCT and nasopharyngoscopy revealed incomplete closure of the velopharyngeal port during a speech in all 6 patients (100%). Two patients (33%) were unable to tolerate a complete nasendoscopic examination. There was no difference between CBCT or nasopharyngoscopy in determining the presence of VPD and noting the severity on a 3-point scale, (P = 0.61) as judged by 4 experienced clinicians.As a functional imaging modality, active-phonation CBCT is a useful adjunct tool for accurate diagnosis of VPD and may be more easily tolerated during a thorough VPD assessment than nasopharyngoscopy. It also provides quantitative data that is useful to augment treatment optimization and surgical planning in this population. Further studies are needed to validate these results.

RESUMO

BACKGROUND: Central nervous system complications are reported in an increasing number of patients with Coronavirus Disease 2019 (COVID-19). COVID-19-related Guillain-Barré syndrome (GBS) is of particular importance given its association with higher mortality rates and prolonged respiratory failure. REVIEW SUMMARY: We conducted a systematic review of published cases for COVID-19-related GBS, and provide a summary of clinical management strategies for these cases. Sixty-three studies, including 86 patients, were included. Seventy-six cases with reported outcome data were eligible for the outcome analysis. Ninety-nine percent of patients were diagnosed with COVID-19 before diagnosis of GBS (median: 14 d prior, interquartile range: 7 to 20). Intravenous immunotherapy (intravenous immunoglobulin: 0.4 g/kg/d for 5 d) was the most frequently used treatment approach. The review indicated that the outcome was not favorable in 26% of cases (persistent neurological deficits). A mortality rate of 3.5% was observed in patients with COVID-19-related GBS. CONCLUSIONS: Although evidence to support specific treatments is lacking, clinicians should consider the benefits of immunotherapy and plasma exchange in addition to the standard antimicrobial and supportive therapies for patients who meet the diagnostic criteria for acute sensory and motor polyradiculoneuritis. Intravenous immunoglobulin treatment alone is not shown to result in improved outcomes or mortality. More extensive studies aimed at exploring the neurological manifestations and complications of COVID-19 and distinctive treatment options for COVID-19-related GBS are warranted.

RESUMO

BACKGROUND: We aimed to longitudinally study the relative research contributions of US and international plastic surgeons by evaluating publications within the premier plastic surgery journal over the last 2 decades. We hypothesized that even with an increased pressure to publish in this journal, the relative research contributions from American plastic surgeons will continue to be the largest overall and in all subspecialties. METHODS: Data for the surgical subspecialty, corresponding author's country of origin, and region were extracted from all original articles in 2 randomly selected monthly issues of Plastic & Reconstructive Surgery (PRS) from the last 2 decades to evaluate longitudinal trends. Data were also extracted from all of the original articles published in PRS for the last 3 years to analyze the recent distribution of research output. RESULTS: During the last 2 decades, the relative proportion of total original articles written by US authors has increased. They have published proportionally more articles in the Reconstructive and Breast field while publishing relatively less in the hand/peripheral nerve field. From the first decade of analysis, US authors wrote relatively fewer articles in the hand/peripheral nerve field, whereas in the second decade, the US authors wrote relatively fewer articles in the Experimental field. In the last 3 years, US authors published relatively fewer articles in the Experimental and Cosmetic fields. CONCLUSIONS: Each country's scientific productivity in PRS is related to funding, interest, patients' demand, and healthcare market pressure. In this study, we see that these factors influence trends within research publications over the last 2 decades.

RESUMO

BACKGROUND: This research was conducted to introduce a patient with rare ovarian mixed germ cell tumor, presented as molar pregnancy. CASE PRESENTATION: The patient was a 16 year old woman admitted with diagnosis of molar pregnancy. Abdominal enlargement was the only complaint. She had a large pelvic mass in physical examination. The first diagnosis was molar pregnancy due to previous ultrasonic reports and positive ßeta HCG. Urine pregnancy test was positive. As suction curettage was performed for her, surprisingly, the size of uterus was normal and no molar tissue was found in pathologic examination. At intraoperative ultrasound exam, an extra-uterine heterogeneous mass was found. Extra-uterine mass was confirmed by CT and MRI done after suction curettage. Mixed germ cell tumor was confirmed by histological examination after laparatomy and removing tumoral mass. Finally, she received Bleomycin, Etoposide and Cisplatin (BEP) regimen in four courses and Vincristine, Actinomycin D (Dactinomycin) and Cyclophosphamide (VAC) regimen in two courses and Diphereline for saving the other ovary. CONCLUSION: Some young patients misinterpret the early symptoms of an ovarian neoplasm as those of pregnancy which can lead to a delay in the diagnosis.

RESUMO

Primary cardiac neoplasms are particularly unusual. Angiosarcoma is the most frequently seen histological subtype and is described by its infiltrating and damaging nature. Inappropriately, primary cardiac angiosarcoma is often missed as a preliminary diagnosis because of its scarcity. We present a 29-year-old previously healthy man with complete heart block and pericardial effusion who was finally diagnosed with angiosarcoma of the right atrium with extension to SVC and IVC.

RESUMO

BACKGROUND: Melasma is a common acquired disorder characterized by symmetric, hyperpigmented patches with an irregular outline, occurring most commonly on the face. It is most prevalent among young to middle-aged women. Although iron overload affects skin pigmentation, effect of iron deficiency on skin is not clear. So, we evaluated serum iron level, ferritin and total iron binding capacity (TIBC) level among nonpregnant women with and without melasma. MATERIALS AND METHODS: A cross-sectional case study was conducted in 2012 at university dermatologic department on 33 nonpregnant women with melasma (case) and 33 nonpregnant women without melasma (control). Serum iron level, TIBC and ferritin in the two groups was measured and compared. RESULTS: Serum iron level was lower in the case group (85 ± 11) in comparison with control group (102 ± 9), but the difference was not significant (P: 0.9). Mean TIBC and Ferritin were higher in the case group (TIBC: 329.4 ± 29, ferritin: 6 ± 18) than the control group (TIBC: 329.3 ± 29, ferritin: 33 ± 6) without significant difference. CONCLUSION: Although the serum iron level was lower in nonpregnant women with mealsma, it was not significant compared with those without melasma.

RESUMO

A 40-year-old man presented with atypical chest pain and fatigue from 15 days ago a suspicious mass in the right ventricle based on a bed side transthoracic echocardiography. Preoperative diagnosis of a cardiac hemangioma comes to mind in a minority of cases. In our case, a cardiac tumor was diagnosed and the vascular nature of the tumor was suggested by vascular blush on the coronary angiography. In addition, right ventriculotomy was the approach of choice in our case because of its inaccessibility and its particular location.
