Background: The general teaching is that increased number of vein repairs in digit replantation leads to improved venous outflow, resulting in lower need for iatrogenic bleeding, lower postoperative transfusion requirements, and better survival rates. The purpose of this study was to determine whether the traditional teaching that emphasizes the repair of multiple veins per arterial anastomosis results in superior survival rates. Methods: A retrospective review of a single urban replant center’s single-digit replants distal to the mid-metacarpal level in adult patients from 2007 to 2017 was performed. Data on patient demographics, mechanism and level of injury, veins repaired, iatrogenic bleeding, postoperative transfusions, and replant survival were obtained. Results: There were a total of 54 single-digit replants. The most common mechanism was lacerations (N = 38), and the most common injury level was at the proximal phalanx (N = 21). All digits were replanted with a single arterial anastomosis—44% via grafting. In all, 0 to 3 veins were repaired per digit (mean = 1.5 veins). The mean transfusion requirement was 1.7 units. The survival rate was 50%. Digits with 1 or 2 veins repaired had lower transfusion requirements (1.1-1.3 units) and higher survival rates (56%-61%) compared with those replanted with 0 or 3 veins repaired (2.9-3.5 transfused units, 25%-29% survival). There were no differences between those digits replanted with either 1 or 2 veins repaired for transfusion requirements or survival. Conclusions: More veins repaired do not necessarily improve survival or possibly venous outflow, calling into question the traditional teaching that 2 veins should be repaired for every arterial anastomosis.

SummaryThe effect of desmopressin (DDAVP) on reducing postoperative blood loss after cardiac surgery has been studied in several randomized clinical trials, with conflicting outcomes. Since most trials had insufficient statistical power to detect true differences in blood loss, we performed a meta-analysis of data from relevant studies. Seventeen randomized, double-blind, placebo-controlled trials were analyzed, which included 1171 patients undergoing cardiac surgery for various indications; 579 of them were treated with desmopressin and 592 with placebo. Efficacy parameters were blood loss volumes and transfusion requirements. Desmopressin significantly reduced postoperative blood loss by 9%, but had no statistically significant effect on transfusion requirements. A subanalysis revealed that desmopressin had no protective effects in trials in which the mean blood loss in placebo-treated patients fell in the lower and middle thirds of distribution of blood losses (687-1108 ml/24 h). In contrast, in trials in which the mean blood loss in placebo-treated patients fell in the upper third of distribution (>1109 ml/24 h), desmopressin significantly decreased postoperative blood loss by 34%. Insufficient data were available to perform a sub-analysis on transfusion requirements. Therefore, desmopressin significantly reduces blood loss only in cardiac operations which induce excessive blood loss. Further studies are called to validate the results of this meta-analysis and to identify predictors of excessive blood loss after cardiac surgery.

Abstract Introduction Osteomyelitis refers to an inflammatory process affecting bone and bone marrow. This study reviews chronic femoral osteomyelitis treatment and outcomes, including economic impact. Method We retrospectively collected data from a consecutive series of 14 chronic femoral osteomyelitis patients treated between January 2013 and January 2020. Data collected include patient demographics, comorbidities, pathogens, complications, treatment protocol and costs. Functional outcome was assessed using EuroQOL five-dimensional interview administration questionnaire (EQ-5D-5L™) and EuroQOL Visual Analogue Scale (EQ-VAS™). Results Of these, 92.9% had one or more osteomyelitis risk factor, including smoking and diabetes. Samples from 78.6% grew at least one pathogen. Only 42.9% achieved remission after initial treatment, but 85.7% were in remission at final follow-up, with no signs of recurrence throughout the follow-up period (mean: 21.4 months). The average treatment cost was £39,249.50 with a net mean loss of £19,080.10 when funding was considered. The mean-derived EQ-5D score was 0.360 and the mean EQ-VAS score was 61.7, lower than their values for United Kingdom’s general population, p = 0.0018 and p = 0.013 respectively. Conclusions Chronic femoral osteomyelitis treatment is difficult, resulting in significant economic burden. With previous studies showing cheaper osteomyelitis treatment at specialist centres, our net financial loss incurred suggests the need for management at specialised centres.

Objective Osteonecrosis (ON), also known as avascular necrosis, is characterized by the collapse of the architectural bone structure secondary to the death of the bone marrow and trabecular bone. Osteonecrosis may accompany many conditions, especially rheumatic diseases. Among rheumatic diseases, osteonecrosis is most commonly associated with systemic lupus erythematosus (SLE). We assessed prevalence and distribution pattern of symptomatic ON in patients with SLE and compare the natural courses of hip and knee ON. Methods 912 SLE patients admitted between 1981 and 2012 were reviewed. SLE patients with symptomatic ON were retrospectively identified both from the existing SLE/APS database. The prevalence of symptomatic ON was calculated; with ON, the joint involvement pattern was determined by examining the distribution of the joints involved, and then the data about the hip and knee joints were entered in the Kaplan-Meier analysis. Kaplan-Meier methods were used to calculate 5- and 10-year rates of ON-related hip (the hip group) and knee survival (the knee group). Results Symptomatic ON developed in various joints in 97 of 912 patients with SLE, and the overall prevalence of ON was detected as 10.6%. The mean age at the time of SLE and ON diagnoses were 27.9 ± 9.9 (14–53) and 34.2 ± 11.3 (16–62) years, respectively. The mean duration from diagnosis of SLE to the first development of ON was 70.7± 60.2 (range = 0–216) months. The most common site for symptomatic ON was the hips (68%, n=66), followed by the knees (38%, n = 37). According to Kaplan-Meier analysis, hip and knee joint survival rates associated with 5-year ON were 51% and 88%, and 10-year survival rates were 43% and 84%, respectively. Conclusion We observed that the prevalence of symptomatic ON in patients with SLE was 10.6%. With the estimated 10-year survival rates of 40% versus 84% for the hip and knee joints, respectively, hip involvement may demonstrate a more aggressive course to end-stage osteoarthritis than the knee involvement.

Pulmonary artery sarcoma (PAS) is a rare and devastating disease. The diagnosis is often delayed, and optimal treatment remains unclear. The aim of this study is to report our experience in the surgical management of this disease. Between 2000 and 2018, 17 patients underwent operations for PAS at our center. The medical records were retrospectively reviewed to evaluate the clinical characteristics, operative findings, the postoperative outcomes, and the long-term results. The mean age at operation was 46.0 ± 12.4 years (range, 26–79 years), and eight (47.1%) patients were male. Six patients underwent tumor resection alone, whereas the other 11 patients received pulmonary endarterectomy (PEA). There were two perioperative deaths. Follow-up was completed for all patients with a mean duration of 23.5 ± 17.6 months (1–52 months). For all 17 patients, the median postoperative survival was 36 months, and estimated cumulative survival rates at 1, 2, 3, and 4 years were 60.0%, 51.4%, 42.9%, and 21.4%, respectively. The mean survival was 37.0 months after PEA and 14.6 months after tumor resection only ( p = 0.046). Patients who had no pulmonary hypertension (PH) postoperatively were associated with improved median survival (48 vs. 5 months, p = 0.023). In conclusion, PAS is often mistaken for chronic pulmonary thromboembolism. The prognosis of this very infrequent disease remains poor. Early detection is essential for prompt and best surgical approach, superior to tumor resection alone, and PEA surgery with PH relieved can provide better chance of survival.

Abstract Objectives This study aimed to retrospectively evaluate clinical and radiographic outcomes of partial pulpotomy performed in permanent teeth with carious pulp exposure. Materials and methods Records of patients undergoing treatment at an undergraduate dental clinic between 2010 and 2019 were screened for partial pulpotomies in teeth with a presumptive diagnosis of normal pulp or reversible pulpitis. The follow-up had to be ≥ 1 year. Patient data were retrieved and analyzed using Mantel-Cox chi square tests and Kaplan–Meier statistics. The level of significance was set at α = 0.05. Results Partial pulpotomy was performed in 111 cases, of which 64 (58%) fulfilled the eligibility criteria. At the time of partial pulpotomy, the mean age was 37.3 (± 13.5) years (age range 18–85). The mean observation period was 3.1 (± 2.0) years. Two early failures (3.1%) and five late failures (7.7%) were recorded. The overall success rate of maintaining pulp vitality was 89.1%, with 98.4% tooth survival. The cumulative pulp survival rates of partial pulpotomy in patients aged < 30 years, between 30 and 40 years, and > 40 years were 100%, 75.5%, and 90.5%, respectively, with no significant difference between the age groups (p = 0.225). At follow-up, narrowing of the pulp canal space and tooth discoloration were observed in 10.9% and 3.1% of cases, respectively. Conclusions Across age groups, partial pulpotomy achieved favorable short and medium-term outcomes in teeth with carious pulp exposure. Clinical relevance Adequate case selection provided, partial pulpotomy is a viable operative approach to treat permanent teeth with deep carious lesions irrespective of patients’ age.

Abstract Background Fractures of the proximal pole of the scaphoid have an increased risk of nonunion due to its tenuous blood supply. The optimal treatment of proximal pole scaphoid nonunions remains controversial. Objectives To review a single surgeon's experience with proximal pole scaphoid nascent nonunions (delayed unions) and nonunions that underwent surgical fixation with a cannulated headless compression screw and local autologous bone graft from the distal radius. Patients and Methods After obtaining Institutional Review Board approval, the electronic medical record of one tertiary care center was queried for patients with the diagnosis of “proximal pole scaphoid fractures” who underwent surgical fixation by a single surgeon over an 11-year period (2006–2017). Fifteen patients met initial query criteria; upon review of records, four patients were excluded due to the acute nature of the fracture, and one was excluded as surgical fixation included a vascularized bone graft. Results The final study cohort consisted of 10 patients with a total of 10 proximal pole scaphoid nonunions. Almost all of the patients in this study were male (9/10 [90%]), and sporting activities were the most common mechanism of injury (8/10 [80%]). Volumetric measurements of the scaphoid fractures on computed tomography (CT) revealed that the mean total volume of the scaphoid was 2.4 ± 0.48 cm3 and the mean volume of the proximal pole fragment was 0.38 ± 0.15 cm3. Postoperative CT scans were performed at a mean of 12.4 weeks (range: 8–16 weeks), with seven (7/10 [70%]) showing signs of complete union and three (3/10 [30%]) demonstrating partial union. None of the patients required additional procedures and there were no complications. Conclusions Our results suggest that proximal pole scaphoid fractures with delayed union and nonunion treated with surgical fixation and autologous local bone graft heal without the need for more complex vascularized procedures. The volume of the proximal pole fragment did not correlate with increased risk of ongoing nonunion after the index procedure. Level of Evidence This is a Level IV, case series study.

The aim of this study is to investigate the mid-term results of 29 hips in 26 patients who underwent acetabular reconstruction using a Kerboull-type acetabular reinforcement device and impaction with hydroxyapatite (HA) granules. The acetabular bone defects were AAOS type II for six hips and type III for 23 hips. The mean Merle d’Aubigné clinical scores were significantly improved after operation. Six hips developed implant migration and breakage, and five of six hips were revised after an average of 5.5 (range 2.0–8.8) years. All hips with thickness of the grafted HA less than 10 mm were stable. As the HA became thicker, the failure rate were significantly increased. The Kaplan–Meier survival rates at 10 years were 73.2%, with 100% and 67.0% for AAOS type II and III defect respectively as the end point was failure condition. Reconstruction using a Kerboull-type acetabular reinforcement device and impaction with HA granules was an alternative method in the absence of adequate allografts.

The survival of the mycobiota on pod and stem debris of soybean produced in a no-tillage system with cover crops of alfalfa, canola, rye, or wheat or with no cover was studied during 1994 and 1995. Fiberglass mesh bags containing pods and stems were assayed every 28 to 31 days to determine the isolation frequency of fungi. Over 90% of the 11,906 isolates obtained were members of the Deuteromycotina. The most common genera isolated were Alternaria, Cercos-pora, Colletotrichum, Epicoccum, Fusarium, and Phoma. Alternaria spp. had the greatest isolation frequencies and constituted 40% of the total cultures. Numbers of total fungi (all fungi isolated) on sampling dates in 1994 were similar to the totals in 1995. In May 1994, the mean isolation rates for many of the fungal species were significantly lower (P = 0.05) in several of the cover crops, but no consistent pattern could be determined. Common soybean pathogens isolated included Colletotrichum spp., Diaporthe spp., and Cercospora kikuchii. Fusarium graminearum, which is responsible for several diseases of maize and wheat, was commonly isolated during this study. Of the Diaporthe spp. (anamorph Phomopsis spp.), 87% were identified as D. phaseolorum var. sojae. Colletotrichum spp. were identified as C. truncatum in 85% of the isolates, C. destructivum (teleomorph Glomerella glycines) in 12%, and both species in 3%. Cercospora kikuchii was more commonly isolated from pods than from stem tissue, and Colletotrichum spp. occurred more frequently on stems. Isolation frequencies of Diaporthe spp. were greater in May of both years than in the preceding months. These results show that no-tillage soybean debris harbors numerous fungi pathogenic to soybean, and producers who grow soybeans continuously may find more disease in this crop and lower yields. Fungi that attack crops such as maize and wheat were commonly isolated from soybean debris in both years, and a no-tillage rotation which includes maize or wheat could result in increased disease in these crops. Isolation frequencies of the fungi from cover crops varied with the sampling date, but no consistent patterns could be determined for a particular cover crop or fungal species. This is the first detailed study of survival rates of soybean, maize, and wheat pathogens that overwinter on soybean debris in a no-tillage system.

Objectives Revascularization according to the angiosome concept is of proven importance for limb salvage in chronic limb threatening ischaemia but it is not always practicable. Bifurcated bypasses could be considered as an option when an endovascular approach is not feasible or has already failed and a single bypass would not allow direct revascularization of the ischaemic area. Bifurcated bypasses are characterized by landing on two different arteries, the main artery (in direct continuity with the foot vessels) and the secondary one (perfusing the angiosome district). The aim of this study is to evaluate the safety and effectiveness of bifurcated bypass in chronic limb threatening ischaemia. Methods Thirty-five patients were consecutively treated with a bifurcated bypass for chronic limb threatening ischaemia from January 2014 to December 2019 in a single vascular surgery centre. Data from clinical records and operative registers were collected prospectively in an electronic database and retrospectively analysed. Primary and primary assisted bypass patency, amputation-free survival, morbidity and mortality rates at 12 and 24 months were analysed. Results Mean follow-up period was 25.1 months (range 2–72 months). Thirty-six bifurcated bypasses were performed on 35 patients (age 75.3 ± 7.2 years; 69.4% were male). According to Wound, Ischemia, foot Infection classification 22.2% belonged to stage 3 and 77.8% to stage 4 and the mean Rutherford’s class was 5.1 ± 0.7. Immediate technical success was 100%. Early mortality and morbidity rates were respectively 5.5%, and 33.3%; foot surgery was performed in 50% of cases with wound healing in all patients. Primary patency and primary assisted bypass patency were 96.7% and 100% at 6 months; 85.2% and 92% at 12 months, 59.9% and 73.4% at 24 months, respectively. Amputation-free survival at 12 and 24 months was, respectively, 95.6% and 78.8%. Overall survival rates at 12 and 24 months were respectively 94.4% and 91.6%. Conclusions Bifurcates bypass can provide good results in patients with chronic limb threatening ischaemia without endovascular option, especially in diabetic ones. Bifurcated bypass is a complex surgical solution, both to be planned and performed, and it is quite invasive for frail patients that should be accurately selected.

Background: Patient satisfaction has a significant bearing on medical therapy compliance and patient outcomes. The purpose of this study was to (1) describe patient satisfaction, as characterized by the Patient Satisfaction Questionnaire-18 (PSQ-18), in the care of patients with chronic rhinosinusitis (CRS) and (2) analyze the impact of comorbidities on satisfaction using the functional comorbidity index (FCI). Methods: Patient demographics, disease severity measures, and PSQ-18 scores for patients with CRS presenting to a tertiary rhinology clinic between November 2019 and April 2020 were collected and analyzed. FCI was calculated retrospectively using the electronic medical record; individual comorbidities were tabulated. Spearman’s correlations followed by multivariate regression was used to assess the relationship between medical comorbidities and PSQ-18. Results: Sixty-nine patients met criteria for analysis. There were no significant differences in age, gender, and Sinonasal Outcomes Test-22 scores between CRS patients with (CRSwNP) and without (CRSsNP) nasal polyps. There was no significant difference in the mean FCI for patients with CRSwNP versus CRSsNP (5.1 and 4.3, respectively) ( P = .843). Similarly, there was no significant difference in the mean sum PSQ-18 score (78/100 in both) between these cohorts ( P = .148). The mean sum PSQ-18 score was not significantly associated with anxiety ( P = .728), depression ( P = .624), or FCI ( P = .282), but was significantly associated with hearing impairment ( P < .001). Conclusion: Patient satisfaction in the care of CRS is generally high with a diagnosis of comorbid hearing impairment demonstrating a negative association with satisfaction in this cohort.
