Maggot debridement therapy: A practical review
Ashley Jordan, Neeraj Khiyani, Steven R Bowers, John J Lukaszczyk, Stanislaw P Stawicki
January-April 2018, 4(1):21-34
DOI
:10.4103/IJAM.IJAM_6_18
Maggot debridement therapy (MDT) has a long and well-documented history. Once a popular wound care treatment, especially prior to the discovery of antibiotics, modern dressings or debridement techniques, MDT fell out of favor after the 1940s. With the increasing prevalence of chronic medical conditions and associated complex and difficult-to-treat wounds, new approaches have become necessary to address emerging issues such as antibiotic resistance, bacterial biofilm persistence and the high cost of advanced wound therapies. The constant search for a dressing and/or medical device that will control pain, remove bacteria/biofilm, and selectively debride necrotic wound material, all while promoting the growth of healthy new tissue, remains elusive. On review of the current literature, MDT comes very close to addressing all of the previously mentioned factors, while at the same time remaining cost-effective. Complications of MDT are rare and side effects are minimal. If patients and providers can look past the obvious anxiety associated with the management and presence of larvae, they will quickly see the benefits of this underutilized modality for healing multiple types of wounds.

The nuclear pore complex: A comprehensive review of structure and function
Stanislaw P Stawicki, Joseph M Steffen
May 2017, 3(3):24-38
DOI
:10.4103/IJAM.IJAM_26_17
The nuclear pore complex (NPC) is an important functional entity of every eukaryotic cell's nuclear membrane. It enables selective transport of materials across the nuclear membrane in an organized and orderly fashion. Substances carried in and out of the nucleus by the NPC include three major groups of molecules: (a) Messenger ribonucleic acid molecules, (b) proteins, and (c) ribonucleoproteins (RNPs). The transport across the nuclear membrane involves adenosine triphosphate hydrolysis in the great majority of cases even though certain guanosine triphosphate-hydrolyzing mechanisms have also been identified. The understanding of the NPC appears crucial to our understanding of certain pathological processes. For example, it has been found that certain human viruses can “trick” our cells into transporting their RNPs into the nucleus using signal peptides similar to the human nuclear-localizing signals. The major challenge of today's research on the NPC resides in identification of over one hundred of its distinct polypeptide units and in determining their functions and interactions. To date, many of the structural proteins involved in the NPC have been identified, but the mechanism of their interactions still remains largely hypothetical. This project discusses the structure and function of the NPC.

Type I, II, and III statistical errors: A brief overview
Parampreet Kaur, Jill Stoltzfus
Jul-Dec 2017, 3(2):268-270
DOI
:10.4103/IJAM.IJAM_92_17
As a key component of scientific research, hypothesis testing incorporates a null hypothesis (H
0
) of no difference in a larger population and an alternative hypothesis (H
1
or H
A
) that becomes true when the null hypothesis is shown to be false. Two potential types of statistical error are Type I error (α, or level of significance), when one falsely rejects a null hypothesis that is true, and Type II error (β), when one fails to reject a null hypothesis that is false. To reduce Type I error, one should decrease the pre-determined level of statistical significance. To decrease Type II error, one should increase the sample size in order to detect an effect size of interest with adequate statistical power. Reducing Type I error tends to increase Type II error, and vice versa. Type III error, although rare, occurs when one correctly rejects the null hypothesis of no difference, but does so for the wrong reason.

Delayed diagnosis of paragonimiasis in Southeast Asian immigrants: A need for global awareness
Sarah Eapen, Eric Espinal, Michael S Firstenberg
May-August 2018, 4(2):173-177
DOI
:10.4103/IJAM.IJAM_2_18
Paragonimiasis is a food-borne parasitic infection that commonly affects humans after ingestion of raw or undercooked crustaceans. The disease is caused by lung flukes of the genus
Paragonimus
, which is endemic to Southeast Asia. In this report, we describe two cases of paragonimiasis diagnosed in North American immigrants from Southeast Asia. The first patient presented with a 5-year history of hemoptysis. The second presented with a 3-week history of productive cough. Both patients were initially treated with antibiotics for presumed pneumonia. The inciting pathogen was not identified by blood, sputum, or stool analyses. Ultimately, surgical resection was required, leading to the diagnosis of paragonimiasis. In the United States and other nonendemic areas, the diagnosis of paragonimiasis is often delayed due to its rarity. Increased awareness and inclusion in differential diagnoses, especially in patients originating from endemic areas, may prevent diagnostic delay and associated morbidity.

Objective:
Several decades of armed conflict at a time of incredible advances in medicine have led to an acknowledgment of the importance of cognitive workload and environmental stress in both war and the health care sector. Recent advances in portable neurophysiological monitoring technologies allow for the continuous real-time measurement and acquisition of key neurophysiological signals that can be leveraged to provide high-resolution temporal data indicative of rapid changes in functional state, (i.e., cognitive workload, stress, and fatigue). Here, we present recent coordinated proof of concept pilot project between private industry, the health sciences, and the USA government where a paper-based self-reporting of workload National Aeronautics and Space Administration Task Load Index Scale (NASA TLX) was successfully converted to a real-time objective measure through an automated cognitive load assessment for medical staff training and evaluation (ACLAMATE).
Methods:
These real-time objective measures were derived exclusively through the processing and modeling of neurophysiological data. This endeavor involved health care education and training with real-time feedback during high fidelity simulations through the use of this artificial modeling and measurement approach supported by Aptima Corporation's FuSE
2
, SPOTLITE, and PM Engine technologies.
Results:
Self-reported NASA TLX workload indicators were converted to measurable outputs through the development of a machine learning-based modeling approach. Workload measurements generated by this modeling approach were represented as a NASA TLX anchored scale of 0–100 and were displayed on a computer screen numerically and visually as individual outputs and as a consolidated team output.
Conclusions:
Cognitive workloads for individuals and teams can be modeled through use of feed forward back-propagating neural networks thereby allowing healthcare systems to measure performance, stress, and cognitive workload in order to enhance patient safety, staff education, and overall quality of patient care.

Point-of-care ultrasound training in Indian emergency medicine programs: A resident's perspective
Vimal Koshy Thomas, Siju Varghese Abraham, Jayaraj Mymbilliy Balakrishnan, S Vimal Krishnan, Ajay Amalakat, Babu Urumese Palatty
Jul-Dec 2017, 3(2):263-267
DOI
:10.4103/IJAM.IJAM_77_16
Background:
Emergency medicine (EM) as a specialty in India is at its infancy. Point-of-care ultrasound (POCUS) is an indispensable tool for the emergency physician (EP). We sought to determine the current experience and resources of POCUS training among EM teaching programs in India.
Methods:
At a national EM board review course, a survey was carried out among 41 residents from 15 different teaching institutes across seven states of India. The survey consisted of questions pertaining to their experience and knowledge in performing basic and advanced POCUS examinations and its utilization in their department.
Results:
Most residents (90.2%) were of the opinion that POCUS is an indispensable tool for the EP. All residents had access to an ultrasound (US) machine, with 90.2% having at least one dedicated machine in their department. 12.1% of the residents utilized POCUS less than five times a day while 14.6% reported using US more than twenty times a day. 68.5% of residents identified the major modality of learning POCUS was from a mentor, and about one-third were exclusively dependent on it. The least utilized sources were books and lectures (19%). Extended focused assessment with sonography in trauma (EFAST) was the most frequently performed examination (95%) and was performed with highest level of confidence. Among the advanced examinations, residents knew how to perform and interpret airway (53.7%) and renal sonography (53.7%) the most while they were least familiar with ocular sonography (19%). 70.1% residents reported that POCUS was utilized for facilitating vascular access, 53.7% for nerve blocks, and paracentesis around 19%. Only 46% reported that other departments rely on their findings to make clinical decisions.
Conclusion:
POCUS was utilized by the residents for different diagnostic examinations and interventions, with the most common being EFAST. The most common learning source of POCUS was from hands-on training by a mentor. There exists a need for guidelines or standardization of POCUS in the EM curriculum to achieve resident competency.

Stereolithography or three-dimensional printing (3DP) is a fast-growing field, with increasing number of health-care applications. As an industry, stereolithography is expected to grow from an estimated $700 million to nearly $9 billion in revenue over the next few years, mainly due to continued advancements and practical implementations of the technology. More established applications of 3DP in medicine involve the creation of wearable assist devices, prosthetics, and orthotics. Research is ongoing in the area of incorporating biologic (including genetic) implementations of 3DP technology, with the long-term goal of three-dimensional printing of organs and tissues that can be subsequently implanted into human body. Given that applications of 3DP in health-care have only recently begun to proliferate, there continues to be paucity of literature in this important and rapidly evolving area of research. In the current review, we sought to present a comprehensive and most current high-level overview of 3DP, with the goal of catalyzing better general understanding and promoting research in 3DP for biomedical applications.

As tattoos become more common, it is likely that practitioners will encounter adverse tattoo reactions with increasing frequency. While some tattoo-related complications (TRCs) may be nonspecific and challenging to diagnose, others present overtly and can be identified quickly by a well-informed practitioner. TRCs occur at both of these extremes, highlighting the need for better awareness and knowledge sharing regarding this heterogeneous group of morbidities. This review is a result of a compilation of the best available clinical evidence across various groupings of TRCs. The authors' intent was to provide the reader with a comprehensive overview of the topic while creating a rich repository of referenced knowledge for future investigations. From the standpoint of frontline health-care providers, effective recognition and management of TRCs require an open-mind, high degree of clinical suspicion, and nonjudgmental approach to a mainstream phenomenon that is still considered by many to be a taboo.

Retained surgical items (RSIs) are much dreaded, preventable complications associated with surgical and other invasive procedures. Despite much effort going into eliminating these “never events” and the associated heavy burden for patients, providers, and institutions, RSIs continue to occur. This manuscript reviews fundamental concepts related to RSI, including risk factors, prevention strategies, technology-assisted detection, team strategies, and pertinent safety education. In addition, we performed a secondary review of a database of all published case reports and series of RSI between 1909 and 2015, focusing on clinical presentation, symptomatology, morbidity, diagnostic workup, pathology findings, and temporal characteristics. Despite a vast body of knowledge regarding RSIs, more needs to be done to help further reduce and prevent these occurrences.

The phenomenon of “brain drain,” (BD) or the unanticipated and significant loss of skilled people and the talent they represent via voluntary turnover, continues to be a significant problem across many academic medical centers. This BD is a result of a multifactorial interplay between personal, professional, institutional, peer-driven, and socioeconomic factors and affects mainly academic healthcare organizations characterized by a specific set of leadership, economic, and competitive preconditions. Institutional impact of BD, both financial and nonfinancial, can be profound and is often underappreciated. Financial considerations of BD include loss of clinical and non-clinical income, contraction of institutional expertise, severance and recruitment expenses, as well as costs of onboarding new faculty. This article focuses on how to identify risk factors for BD at both institutional and personnel levels. Proposed steps for prevention and early intervention are outlined.

Retaining talent at academic medical centers
Rebecca Jeanmonod
January-June 2016, 2(1):46-51
DOI
:10.4103/2455-5568.183323
Background:
Faculty turnover is a major problem at academic medical institutions. A minority of medical school graduates choose academic careers and those that do have a high rate of attrition.
Methods:
We conducted an in-depth review of the medical and business literature to determine high-frequency reasons for faculty attrition, and explored what strategies have been suggested or employed to reduce this trend.
Results:
Medical and business literature demonstrate that faculty morale, perceptions of work-life balance, support from the institution, faculty development, rewards, protected time, relationship with superiors, and role clarity all play a role in faculty decisions to leave an institution. Institutions have shown some success in reducing attrition through recruiting to retain, formal mentorship programs, novel reward programs tied to longevity, faculty development, and attention to faculty professional and personal goals.
Conclusions:
Academic medical centers should conduct retention analyses to determine commonly cited reasons for attrition at the global and departmental level. Measures to improve retention can be taken at every step of the recruitment, training, and seasoned employee level. Retention efforts are guided and enhanced by open and frequent communication between faculty and administration.

There are growing problems with the supply of trauma surgeons and/or willingness to participate in trauma care. Solutions proposed include the use of nonsurgeon providers and the development of an acute care surgery model to enhance the attractiveness of training in the field. We propose that immediate modification of clinical operations within trauma centers may address some of these problems and improve patient care and safety. The use of structured shift work models with efficient systems for communication and handoff may improve workforce utilization and vitality both in the near and far term.

A cross-sectional online evaluation of burnout risk factors among general surgical residents in Canada
Simon Timothy Adams, Zeeshan Rana, Rhonda Bryce, Francis Christian
January-April 2018, 4(1):35-49
DOI
:10.4103/IJAM.IJAM_83_17
Background:
Burnout is hallmarked by physical and psychological exhaustion, coupled with cynicism and disengagement. Evidence suggests that affected physicians not only suffer personally, but that patient safety and clinical outcomes are also negatively affected. This study aimed to identify potentially remediable risks for burnout among residents enrolled in Canadian general surgery programs.
Methods:
In this cross-sectional design, a questionnaire was distributed to every general surgery resident in the 15 programs consenting to participate. Questions examined the following five domains: demographics, working patterns, attitudes toward residency, life experiences, and lifestyle/outlook. Respondents' risks of burnout were assessed using the Maslach Burnout Inventory
™
. Univariate analysis and then multiple logistic regression were used to assess predictors.
Results:
A total of 114 completed questionnaires were received (22%). Of these residents, 39 (34%) met the criteria for high burnout risk. Inadequate personal/family time, a personal history of mental health or substance abuse-related issues, and moderately to poorly approachable staff/senior residents were all significantly associated with a high burnout risk (odds ratio [OR] =4.3, 95% confidence interval [CI] =1.6, 11.2,
P
= 0.003; OR =6.0, 95% CI = 1.6, 21.9,
P
= 0.007; and OR = 4.6, 95% CI = 1.7, 12.5,
P
= 0.003 respectively). Predicted high burnout risk probability with none of the above factors was 10%, increasing up to 40%, 75%, and 93% with one, two, or all of these risk factors present respectively.
Conclusion:
One-third of general surgery residents in Canada are at high burnout risk. Residency programs may have considerable influence over factors associated with this outcome to the benefit of residents, staff, and patients.

Fecal microbiota transplantation (FMT) re-emerged over the last decade, primarily in response to the escalating problem of health-care-associated
Clostridium difficile
(CD) infection (CDI). Increasing virulence and antibiotic resistance of CD prompted intensified efforts to broaden therapeutic options for this emerging health threat. It is well established that homeostasis of intestinal flora (or microbiota) is critical to human well-being. Introduction and misuse of various health-care related interventions, including antibiotics and gastric acid-reducing agents, contributed to the current state of crisis. Common therapeutic options for CDI include antibiotics, probiotics, and surgery. More recently, there has been as shift toward the utilization of FMT as a second-line option for severe/complicated CDI. The aim of this review is to provide health-care professionals with a concise summary of management options for CDI, with special focus on FMT and its indications, contraindications, and implementation experiences.

Leading mindfully and managing compassionately: Strategies for meeting today's challenges in academic medicine
Bryan A Wilson, Vijaya B Reddy, Monte S Willis
January-April 2018, 4(1):12-20
DOI
:10.4103/IJAM.IJAM_63_17
Academic medical centers (AMCs) are no strangers to operating in a challenging environment; however, the challenges have never been more significant and the future more uncertain than now largely due to the changes affected by the health care reform and the possibility of more changes stemming from the political arena. The looming threat to the triple mission of outstanding clinical care, education, and research can only be successfully thwarted by a shift in the mindset of health-care leadership to better align with winning strategies for a volatile environment. Adapting some of the proven leadership strategies in a business setting may be beneficial in navigating the challenging and changing healthcare arena. Two strategies are highlighted with examples in this review: the adaptation of a “growth” mindset over a “fixed” mindset, and application of compassionate management during challenging times, both of which have been shown to improve the overall financial performance of a company. Integration of these strategies and allocation of resources to professional growth and leadership development can equip health system managers, physicians, staff and trainees with the adaptive tools necessary for meeting the increasing demands and ensuring the continued success of an AMC. With nearly 6000 pathologists and 2200 residents working in an academic setting, an increasing emphasis on leadership development and management tools for pathology professionals is timely.

Retroperitoneal sarcomas (RS) are malignant tumors arising from mesenchymal cells, which are usually located in adipose, muscle, or connective tissue. RSs represent approximately 15% of all sarcomas and approximately 33–55% of all retroperitoneal tumors. The most common variants of RS include liposarcoma (40%), leiomyosarcoma (30%), and malignant fibrous histiocytoma (<10%). This article reviews the most important clinical characteristics of RSs, focusing on high-yield facts frequently encountered on standardized exams.

Key points: (a) Reexpansion pulmonary edema-RxPE– is a rare form of acute lung injury, with an incidence of approximately 1% following evacuation of a pneumothorax; (b) RxPE usually follows rapid reinflation of collapsed lung parenchyma; (c) The most common factor associated with RxPE is the duration of lung collapse– more than 3 days seems to be the critical amount of time; (d) The pathophysiologic changes associated with RxPE are complex and not yet fully understood; (e) The pathologic process results from a combination of rapid pulmonary reexpansion with concurrent mechanical alveolar injury, decrease in surfactant and regional lung tissue hypoxemia, inflammatory cell migration and release of inflammatory mediators, and the resulting changes in capillary-alveolar barrier occurring concurrently with increased capillary/hydrostatic pressures; (f) Clinical manifestations of RxPE vary from minimal symptoms to life-threatening hypoxia and cardio-respiratory collapse; (g) The patient may experience dyspnea, thoracic pain, cough with or without pink/foamy sputum, cyanosis, rales and stertors on auscultation. Other clinical symptoms may include fever, nausea, vomiting, tachycardia, and hypotension; (h) The symptoms of RxPE usually appear within the first two hours following pulmonary reexpansion, but may be delayed by as many as 24-48 h; (i) RxPE usually lasts clinically for as long as 1-2 days, but may take anywhere from 5 to 7 days to resolve; (j) Critical care practitioners should be familiar with the most common factors involved in the pathogenesis of RxPE; (k) The knowledge of these predisposing factors and the ability to effectively treat RxPE are important to prevention and treatment of this potentially fatal condition.

Missed traumatic injuries: A synopsis
Stanislaw P Stawicki, David E Lindsey

DOI
:10.4103/IJAM.IJAM_5_17
The ultimate goal in trauma resuscitation is to promptly identify and treat all injuries. Despite clinical and technological advances in the diagnosis and treatment of trauma patients, missed injuries continue to significantly affect modern trauma services. Delayed diagnosis and missed injuries have the potential to exacerbate the severity of the initial insult, and may result in permanent disability or even mortality. Moreover, missed injuries add significantly to the length of hospitalization and overall costs of trauma patient care. This article will discuss the common themes associated with missed injuries, and will highlight steps that practitioners can take to minimize delays in diagnosis and to reduce the number of missed injuries. This article begins with basic definitions, followed by a discussion of literature pertaining to, and factors associated with, missed injuries. We will then focus on specific mechanisms and injury patterns, as well as the corresponding injury-specific diagnostic and treatment pitfalls that have to be considered in order to avoid missed injuries.
