RESUMO

Tumoral calcinosis (TC) is a rare condition defined by the accumulation of calcium salts in soft tissues surrounding joints, most commonly large joints. Chronic joint inflammation in the setting of local hyperphosphatemia leads to interruption and dysfunction of tissue repair and generates breakdown products that subsequently calcify and accumulate. We present a case of a 42-year-old man with a history of end-stage renal disease on dialysis presenting to the clinic with a painless digital mass of his right long finger at the proximal interphalangeal joint. Our initial impression was a splinter abscess based on presentation and patient history. Although our patient's presentation of traumatic, painless TC of the hand secondary to end-stage renal disease is rare, the pathogenic mechanisms behind TC support this presentation. The authors recommend including TC within the differential of presentations similar to that of chronic abscess or giant cell tumor, especially when their medical history includes end-stage renal disease.

RESUMO

BACKGROUND: Mercury, an element with threats of severe toxic insult to humans and no biological function, has a surprisingly extensive record of human exposure. Regardless of hesitancies toward its harmfulness, it has been historically identified with an almost supernatural power to provide protection from evil and sickness, give good fortune, lend aid in athletic undertakings, or even allow one to achieve immortality. Mercury poisoning is an iatrogenic disease even today as people attempt to achieve these effects through volitional injections into their body by practitioners. Although an uncommon practice in the United States, awareness of patient presentation after volitional injections of elemental mercury is necessary for appropriate treatment of these patients. We aim to increase awareness of the cultural practice of subcutaneous injections of mercury, as it is uncommonly seen in the United States, to contribute a broader understanding to the patient's medical presentation and describe an approach and the impact of medical and surgical intervention. METHODS: In this report, we describe a rare case of elemental mercury poisoning secondary to volitional subcutaneous injection to the arm. Initial management of care through chelation therapy and monitoring of renal and serum mercury levels in addition to symptoms of systemic spread was overseen by an internal medicine physician and poison control. Surgical intervention via full-thickness excision of the visible mercury to the right arm followed by local flap and skin grafting reconstruction was performed. CONCLUSIONS: Mercury poisoning from intentional subcutaneous administration is an uncommon patient presentation in the United States; however, knowledge of management of this rare condition is important for effective management of iatrogenic mercury toxicity.

RESUMO

The development of small-diameter vascular grafts requires testing in large animal models before advancing to clinical trials. Vascular graft interposition implantation in sheep carotid arteries (CAs) is the most widely used model, but ovine CAs are prone to severe spasm following surgical manipulation, potentially impairing graft performance assessment. There is paucity in the literature on reducing sheep CA spasm using effective vasodilator therapeutic protocols. In this study, four healthy Merino cross White Suffolk wethers (1-2 years, 52.1 ± 0.8 kg) underwent CT angiography and CA graft surgery. CT angiography using iodinated contrast agent was performed with innominate artery access through the CA or ascending aortic arch access through the femoral artery. Sheep then underwent right CA sham surgery or left CA vascular graft implantation. A variety of vasodilators, including papaverine, sodium nitroprusside, verapamil, and their combination, were tested for preventing or treating CA spasms intraoperatively. Blood flow was reassessed immediately after CA surgery using CT angiography. The results showed that innominate artery access through the CA for CT angiography in sheep induced presurgical CA spasm with reduced arterial flow. Conversely, ascending aortic arch access through the femoral artery for CT angiography did not cause CA spasm and maintained arterial flow. During CA graft surgery, surgical trauma induced CA spasm, which was prevented by localized intra-arterial administration of vasodilators papaverine hydrochloride and verapamil before significant surgical manipulation.

RESUMO

BACKGROUND: Enhanced recovery after surgery (ERAS) protocols have been implemented across surgical disciplines, including cranial vault remodeling for craniosynostosis. The authors aim to describe the implementation of an ERAS protocol for cranial vault remodeling procedures performed for patients with craniosynostosis at a tertiary care hospital. DESCRIPTION: Institutional review board approval was received. All patients undergoing a cranial remodeling procedure for craniosynostosis at the authors' institution over a 10-year period were collected (n = 168). Patient and craniosynostosis demographics were collected as well as operative details. Primary outcome measures were intensive care unit length of stay (ICU LOS) and narcotic usage. Chi squared and independent t-tests were employed to determine significance. A significance value of 0.05 was utilized. RESULTS: During the time examined, there were 168 primary cranial vault remodeling procedures performed at the authors' institution - all of which were included in the analysis. Use of the ERAS protocol was associated with decreased initial 24-hour morphine equivalent usage (p < 0.01) and decreased total morphine equivalent usage (p < 0.01). Patients using the ERAS protocol experienced a shorter ICU LOS (p < 0.01), but the total hospital length of stay was unchanged. CONCLUSION: This study reiterates the benefit of developing and implementing an ERAS protocol for patients undergoing cranial vault remodeling procedures. The protocol resulted in an overall decreased ICU LOS and a decrease in narcotic use. This has implications for ways to maximize hospital reimbursement for these procedures, as well as potentially improve outcomes.

RESUMO

The American Society for Surgery of the Hand and British Society for Surgery of the Hand produce patient-focused information above the sixth-grade readability recommended by the American Medical Association. To promote health equity, patient-focused content should be aimed at an appropriate level of health literacy. Artificial intelligence-driven large language models may be able to assist hand surgery societies in improving the readability of the information provided to patients. The readability was calculated for all the articles written in English on the American Society for Surgery of the Hand and British Society for Surgery of the Hand websites, in terms of seven of the commonest readability formulas. Chat Generative Pre-Trained Transformer version 4 (ChatGPT-4) was then asked to rewrite each article at a sixth-grade readability level. The readability for each response was calculated and compared with the unedited articles. Chat Generative Pre-Trained Transformer version 4 was able to improve the readability across all chosen readability formulas and was successful in achieving a mean sixth-grade readability level in terms of the Flesch Kincaid Grade Level and Simple Measure of Gobbledygook calculations. It increased the mean Flesch Reading Ease score, with higher scores representing more readable material. This study demonstrated that ChatGPT-4 can be used to improve the readability of patient-focused material in hand surgery. However, ChatGPT-4 is interested primarily in sounding natural, and not in seeking truth, and hence, each response must be evaluated by the surgeon to ensure that information accuracy is not being sacrificed for the sake of readability by this powerful tool.

RESUMO

BACKGROUND: Rehabilitation after hip disarticulation and hemipelvectomy amputations can be challenging, and many opt to forego prosthetic limb use. There is limited evidence on characteristics that result in successful prosthetic use; therefore, our study aimed to identify these to help guide patient expectations. METHODS: A retrospective review was performed on patients seen at a UK tertiary prosthetic center in the past 5 years with hip disarticulation or hemipelvectomy amputations. Details and etiology of amputation, length between assessment and delivery of prosthesis, goals, reasons for abandonment, and outcomes were recorded. Successful prosthetic use was defined as the use of a prosthesis at least 3 times a week. Characteristics were compared using odds ratios and Fisher exact test. RESULTS: Twenty-seven patient notes were analyzed: 42% female, 58% male, and age range 14-90. Thirty percent had a hemipelvectomy, and 70% had a hip disarticulation. Neoplasia accounted for 78% of etiologies followed by trauma 15% and infected endoprosthesis 7%. Sixty-seven percent trialed a walking prosthesis; 33% of these stopped eventually. There were no statistically significant findings of factors increasing odds of successful prosthetic use. However, age significantly increased the odds of being given a trial of a prosthesis. CONCLUSION: Although younger patients are more likely to be given the opportunity to trial a walking prosthesis, age does not seem to affect the overall outcome alone. In cases of neoplasia, there is often a delayed start to rehabilitation and prosthetic use, which may affect eventual success. Further studies are required to define the optimum characteristics for successful prosthetic use at higher amputation levels.

RESUMO

BACKGROUND: Modern oncological therapies together with chemotherapy and radiotherapy have broadened the agents that can cause cardiac sequelae, which can manifest for pediatric oncology patients while on active treatment. Recommendations for high-risk patients who should be monitored in a pediatric cardio-oncology clinic have previously been developed by expert Delphi consensus by our group. In 2022 we opened our first multidisciplinary pediatric cardio-oncology clinic adhering to these recommendations in surveillance and management. OBJECTIVES: Our pediatric cardio-oncology clinic aimed to: (i) Document cardiovascular toxicities observed within a pediatric cardio-oncology clinic and. (ii) Evaluate the applicability of the Australian and New Zealand Pediatric Cardio-Oncology recommendations. METHODS: Monthly multidisciplinary cardio-oncology clinics were conducted in an Australian tertiary pediatric hospital. Structured standardised approaches to assessment were built into the electronic medical record (EMR). All patients underwent baseline echocardiogram and electrocardiogram assessment together with vital signs in conjunction with standard history and examination. RESULTS: Nineteen (54%) individuals had a documented cardiovascular toxicity or pre-existing risk factor prior to referral. The two most common cardiovascular toxicities documented during clinic review included Left Ventricular Dysfunction (LVD) and hypertension. Of note 3 (8.1%) patients had CTCAE grade III LVD. An additional 10 (27%) patients reviewed in clinic had CTCAE grade I hypertension. None of these patients had hypertension noted within their referral. Cascade testing for cardiac history was warranted in 2 (5.4%) of patients. CONCLUSIONS: Pediatric cardio-oncology clinics are likely beneficial to documenting previously unrecognised cardiotoxicity and relevant cardiac family histories, whilst providing an opportunity to address lifestyle risk factors.

RESUMO

Anatomical variations within Guyon's canal such as an accessory abductor digiti minimi are described as causes of ulnar nerve compression. Here we present a unique case of delayed ulnar neuropathy following treatment of left fourth metacarpal base fracture with percutaneous pinning fixation and an uncomplicated two month postoperative course. He returned with new ulnar sensory loss and motor weakness. EMG demonstrated nerve compression with CT identifying an accessory abductor digiti minimi in Guyon's canal. Following Guyon's canal release with partial accessory muscle resection, there was immediate sensory and progressive motor recovery with resolution of clawing. Delayed compression by an accessory abductor digiti minimi following trauma has not been described, suggestive of double-crush phenomenon. The accessory muscle was an asymptomatic variable (first "crush") and with the second "crush" of post-surgical changes resulting in pathological nerve compression. With delayed onset ulnar neuropathy after trauma, surgeons should consider possible accessory structures.

RESUMO

Acquired buried penis is a condition that can have detrimental physical and psychological consequences for patients. Factors such as elevated BMI, chronic scrotal lymphedema, hidradenitis suppurativa, and chronic inflammation can lead to the condition. Surgical intervention is the treatment of choice for advanced disease. Following IRB approval, a retrospective chart review was performed for patients with a diagnosis of acquired buried penis who required surgical intervention. Details of patient history, surgical management including intraoperative and post-operative photography, and complications were reviewed. Seven patient cases were reviewed. The average age at time of surgery was 44 with a mean weight of 344 pounds and an average BMI of 48. Severe scrotal lymphedema and hidradenitis were common concurrent comorbidities. Concurrent scrotoplasty and infraumbilical panniculectomy were standard parts of the operations. Native glans skin was salvageable in all but one case. Penile shaft skin was reconstructed with skin grafts or adjacent tissue transfer. 88% of the cases had some element of wound dehiscence post-operatively. Surgical management of an acquired buried penis can be challenging. The patient demographic with the disease is frequently complicated by morbid obesity, concurrent lymphedema, or hidradenitis. Post-operative complications are expected. The surgical techniques presented can aid in simplifying the management of this challenging surgical population.

RESUMO

Chronic unresolving inflammation is emerging as a key underlying pathological feature of many if not most diseases ranging from autoimmune conditions to cardiometabolic and neurological disorders. Dysregulated immune and inflammasome activation is thought to be the central driver of unresolving inflammation, which in some ways provides a unified theory of disease pathology and progression. Inflammasomes are a group of large cytosolic protein complexes that, in response to infection- or stress-associated stimuli, oligomerize and assemble to generate a platform for driving inflammation. This occurs through proteolytic activation of caspase-1-mediated inflammatory responses, including cleavage and secretion of the proinflammatory cytokines interleukin (IL)-1ß and IL-18, and initiation of pyroptosis, an inflammatory form of cell death. Several inflammasomes have been characterized. The most well-studied is the nucleotide-binding domain (NOD)-like receptor protein 3 (NLRP3) inflammasome, so named because the NLRP3 protein in the complex, which is primarily present in immune and inflammatory cells following activation by inflammatory stimuli, belongs to the family of nucleotide-binding and oligomerization domain (Nod) receptor proteins. Several NLRP3 inflammasome inhibitors are in development, all with multi-indication activity. This review discusses the current status, known mechanisms of action, and disease-modifying therapeutic potential of RRx-001, a direct NLRP3 inflammasome inhibitor under investigation in several late-stage anticancer clinical trials, including a phase 3 trial for the treatment of third-line and beyond small cell lung cancer (SCLC), an indication with no treatment, in which RRx-001 is combined with reintroduced chemotherapy from the first line, carboplatin/cisplatin and etoposide (ClinicalTrials.gov Identifier: NCT03699956). Studies from multiple independent groups have now confirmed that RRx-001 is safe and well tolerated in humans. Additionally, emerging evidence in preclinical animal models suggests that RRx-001 could be effective in a wide range of diseases where immune and inflammasome activation drives disease pathology.

RESUMO

During April-July 2022, outbreaks of severe acute hepatitis of unknown etiology (SAHUE) were reported in 35 countries. Five percent of cases required liver transplantation, and 22 patients died. Viral metagenomic studies of clinical samples from SAHUE cases showed a correlation with human adenovirus F type 41 (HAdV-F41) and adeno-associated virus type 2 (AAV2). To explore the association between those DNA viruses and SAHUE in children in Ireland, we quantified HAdV-F41 and AAV2 in samples collected from a wastewater treatment plant serving 40% of Ireland's population. We noted a high correlation between HAdV-F41 and AAV2 circulation in the community and SAHUE clinical cases. Next-generation sequencing of the adenovirus hexon in wastewater demonstrated HAdV-F41 was the predominant HAdV type circulating. Our environmental analysis showed increased HAdV-F41 and AAV2 prevalence in the community during the SAHUE outbreak. Our findings highlight how wastewater sampling could aid in surveillance for respiratory adenovirus species.

RESUMO

The Ozone Water-Land Environmental Transition Study, 2018 (OWLETS-2) measured total non-methane hydrocarbons (TNMHC) and EPA PAMS Volatile Organic Compounds (VOCs) on an island site in the northern Chesapeake Bay 2.1 and 3.4 times greater in concentration, respectively, than simultaneous measurements at a land site just 13 km away across the land-water interface. Many PAMS VOCs had larger concentrations at the island site despite lower NEI emissions over the water, but most of the difference comprised species generally consistent with gasoline vapor or exhaust. Sharp chemical differences were observed between the island and mainland and the immediate air ~300 m above the water surface observed by airplane. Ozone formation potential over land was driven by propene and isoprene but toluene and hexane were dominant over the water with little isoprene observed. VOC concentrations over the water were noted to increase diurnally with an inverse pattern to land resulting in increasing NOx sensitivity over the water. Total reactive nitrogen was lower over the water than the nearby land site, but reservoir compounds (NOz) were greater. Ozone production rates were generally slow (~5 ppb hr-1) both at the surface and aloft over the water, even during periods of high ozone (>70 ppbv) at the water surface. However, specific events showed rapid ozone production >40 ppb hr-1 at the water's surface during situations with high VOCs and sufficient NOx. VOC and photochemistry patterns at the island site were driven by marine sources south of the island, implicating marine traffic, and indicate ozone abatement strategies over land may not be similarly applicable to ozone over the water.Implications: Measured chemical properties and patterns driven primarily by marine traffic sources over water during ozone conducive conditions were starkly different to immediately adjacent land sites, implying ozone abatement strategies over land may not be similarly applicable to ozone over the water.

RESUMO

Being aware of the variants of upper extremity anatomy is of utmost importance to a surgeon. This case report describes a patient who presented with two separate wrist masses. Operative exploration was planned, and both the structures were investigated. The distal mass was identified as a volar wrist ganglion, and the more proximal mass was identified as the muscle belly of a reversed palmaris longus muscle. Incidentally, it was noted that the patient had a patent, persistent median artery. Although many variants of the palmaris longus have been described, as have been cases of a persistent median artery, both have not been previously documented in a single patient. Although this is rare, having knowledge of possible anatomic variations is valuable for any surgeon operating on the upper extremity.

RESUMO

AIMS: To identify biomarkers of cardiomyopathy in patients with type 2 diabetes mellitus (T2DM) using cardiovascular magnetic resonance (CMR) and to identify associations between functional status, metabolomic profile and myocardial fibrosis. METHODS: In this prospective case control study, patients (n = 49) with T2DM without significant coronary artery disease, and matched controls (n = 18) underwent CMR, cardiopulmonary exercise testing, and plasma metabolomic analyses. RESULTS: Patients with T2DM (n = 49, median [interquartile range] age 61 [56-63] years, 61% male, diabetes duration 11 [7-20] years), historical HbA1c 7.6% (60 mmol/mol) (6.9-8.6) and matched controls (n = 18) were examined. Study patients had increased myocardial extracellular volume (ECV) (26.9 [23.8-30.0] vs 23.4 [22.4-25.5) %, p < 0.001). Increased ECV was associated with male sex (p = 0.04), time with T2DM (p = 0.02), reduced peak VO2 (R2 = 0.48, p = 0.01), increased circulating choline (p = 0.002) and cysteamine (p = 0.002) both of which were also associated with reduced peak VO2 (p < 0.025 and 0.014 respectively). CONCLUSIONS: Patients with well-controlled T2DM without significant coronary disease exhibit focal and diffuse myocardial fibrosis and diffuse myocardial fibrosis is associated with reduced exercise tolerance and metabolites. Plasma metabolites may provide mechanistic insights into diffuse myocardial fibrosis, and cardiopulmonary fitness.

RESUMO

BACKGROUND: A previous genome-wide association study identified several loci with genetic variants associated with prostate cancer survival time in two cohorts from Sweden. Whether these variants have an effect in other populations or if their effect is homogenous across the course of disease is unknown. METHODS: These variants were genotyped in a cohort of 1,298 patients. Samples were linked with age, PSA level, Gleason score, cancer stage at surgery, and times from surgery to biochemical recurrence to death from prostate cancer. SNPs rs2702185 and rs73055188 were tested for association with prostate cancer-specific survival time using a multivariate Cox proportional hazard model. SNP rs2702185 was further tested for association with time to biochemical recurrence and time from biochemical recurrence to death with a multi-state model. RESULTS: SNP rs2702185 at SMG7 was associated with prostate cancer-specific survival time, specifically the time from biochemical recurrence to prostate cancer death (HR, 2.5; 95% confidence interval, 1.4-4.5; P = 0.0014). Nine variants were in linkage disequilibrium (LD) with rs2702185; one, rs10737246, was found to be most likely to be functional based on LD patterns and overlap with open chromatin. Patterns of open chromatin and correlation with gene expression suggest that this SNP may affect expression of SMG7 in T cells. CONCLUSIONS: The SNP rs2702185 at the SMG7 locus is associated with time from biochemical recurrence to prostate cancer death, and its LD partner rs10737246 is predicted to be functional. IMPACT: These results suggest that future association studies of prostate cancer survival should consider various intervals over the course of disease.

RESUMO

Background: Hypoplastic left heart syndrome (HLHS) with either intact atrial septum (IS) or highly restrictive interatrial communication (HRIC) is associated with poor survival. Immediate postpartum access to cardiac therapy and timely left atrial decompression (LAD) are paramount to a successful outcome. We describe herein our evolving approach to LAD and report interstage and longer-term results. Methods: We retrospectively identified neonates with HLHS IS/HRIC requiring LAD between 2005 and 2019. All babies had prenatal/postnatal echocardiography. Our LAD strategy evolved over time from attempt at transcatheter balloon atrial septostomy (BAS) to surgical septectomy with inflow occlusion, to hybrid trans-atrial stent implantation. Results: Twelve neonates required LAD at a median time of 14 (0.5-31) hours after birth. Five patients underwent BAS that proved successful in 2 cases. Of the 3 unsuccessful cases, 2 required extra-corporeal membrane oxygenation (ECMO) support and died subsequently; one underwent hybrid trans-atrial stent implantation. Of the remaining 7 patients, 3 underwent surgical septectomy with inflow-occlusion and 4 underwent hybrid trans-atrial stent implantations. Overall, 8 patients survived LAD and reached Norwood palliation. Three of the 8 required ECMO postoperatively. There was no hospital mortality after Norwood stage 1 palliation and interstage survival was 100%. Six patients successfully underwent Glenn shunt (superior cavopulmonary anastomosis) and 5 have completed total cavopulmonary connection. Conclusions: Our experience suggests that prompt postnatal LAD can be safely achieved with careful multidisciplinary planning and accurate antenatal diagnosis. In our hands, hybrid trans-atrial septal stent insertion appears to be a safe approach which combines the versatility of transcatheter techniques together with the effectiveness of surgical control.

RESUMO

OBJECTIVES: Ventricular assist device (VAD) for systemic right ventricular (RV) failure patients post-atrial switch, for transposition of the great arteries (TGA), and those with congenitally corrected TGA has proven useful to reduce transpulmonary gradient and bridge-to-transplantation. The purpose of this study is to describe our experience of VAD in systemic RV failure and our move towards concomitant tricuspid valve replacement (TVR). METHODS: This is a single-centre retrospective study of consecutive adult patients receiving HeartWare VAD for systemic RV failure between 2010 and 2019. From 2017, concomitant TVR was performed routinely. Demographic, clinical variables and echocardiographic and haemodynamic measurements pre- and post-VAD implantation were recorded. Complications on support, heart transplantation and survival rates were described. RESULTS: Eighteen patients underwent VAD implantation. Moderate or severe systemic tricuspid regurgitation was present in 83.3% of patients, and subpulmonic left ventricular impairment in 88.9%. One-year survival was 72.2%. VAD implantation was technically feasible and successful in all but one. Post-VAD, transpulmonary gradient fell from 16 (15-22) to 10 (7-13) mmHg (P = 0.01). Patients with TVR (n = 6) also demonstrated a reduction in mean pulmonary and wedge pressures. Furthermore, subpulmonic left ventricular end-diastolic dimension (44.3 vs 39.6 mm; P = 0.03) and function improved in this group. After 1 year of support, 72.2% of patients were suitable for transplantation. CONCLUSIONS: VAD is an effective strategy as bridge-to-candidacy and bridge-to-transplantation in patients with end-stage systemic RV failure. Concomitant TVR at the time of implant is associated with better early haemodynamic and echocardiographic results post-VAD.

RESUMO

Biobanking in health care has evolved over the last few decades from simple biological sample repositories to complex and dynamic units with multi-organizational infrastructure networks and has become an essential tool for modern medical research. Cardiovascular tissue biobanking provides a unique opportunity to utilize cardiac and vascular samples for translational research into heart failure and other related pathologies. Current techniques for diagnosis, classification, and treatment monitoring of cardiac disease relies primarily on interpretation of clinical signs, imaging, and blood biomarkers. Further research at the disease source (i.e. myocardium and blood vessels) has been limited by a relative lack of access to quality human cardiac tissue and the inherent shortcomings of most animal models of heart disease. In this review, we describe a model for cardiovascular tissue biobanking and databasing, and its potential to facilitate basic and translational research. We share techniques to procure endocardial samples from patients with hypertrophic cardiomyopathy, heart failure with reduced ejection fraction, and heart failure with preserved ejection fraction, in addition to aortic disease samples. We discuss some of the issues with respect to data collection, privacy, biobank consent, and the governance of tissue biobanking. The development of tissue biobanks as described here has significant scope to improve and facilitate translational research in multi-omic fields such as genomics, transcriptomics, proteomics, and metabolomics. This research heralds an era of precision medicine, in which patients with cardiovascular pathology can be provided with optimized and personalized medical care for the treatment of their individual phenotype.
