Second-Order Statistical Methods GLCM for Authentication Systems
Authors: Taha Mohammed , Ahmed Hanaa
Published: April 2021

For many uses, biometric systems have gained considerable attention. Iris identification was One of the most powerful sophisticated biometrical techniques for effective and confident authentication. The current iris identification system offers accurate and reliable results based on near-infrared light (NIR) images when images are taken in a restricted area with fixed-distance user cooperation. However, for the color eye images obtained under visible wavelength (VW) without collaboration among the users, the efficiency of iris recognition degrades because of noise such as eye blurring images, eye lashing, occlusion, and reflection. This work aims to use the Gray-Level Co- occurrence Matrix (GLCM) to retrieve the iris's characteristics in both NIR iris images and visible spectrum. GLCM is second-order Statistical-Based Methods for Texture Analysis. The GLCM-based extraction technology was applied after the preprocessing method to extract the pure iris region's characteristics. The Energy, Entropy, Correlation, homogeneity, and Contrast collection of second-order statistical features
are determined from the generated co-occurrence matrix, Stored as a vector for numerical features. This approach is used and evaluated on the CASIA v1and ITTD v1 databases as NIR iris image and UBIRIS v1 as a color image. The results showed a
high accuracy rate (99.2 %) on CASIA v1, (99.4) on ITTD v1, and (87%) on UBIRIS v1 evaluated by comparing to the other methods

Published: April 2021

Underwater Remotely Operated vehicle is a tethered mobile vehicle most often used to monitor underwater oil and gas drilling inspection, telecommunications and homeland security. The main focus of this research is to design a vehicle at low cost which is safe, portable, and easy to use while increasing the maneuverability and efficiency to reach a depth of 5 meters. While conducting research a unique design is selected based on a novel fin propulsion mechanism rather than propellers. Propellers though have high speed but cannot work on low flow rates and their blades can be damaged if jelly fish or other material is struck in its shaft. Two shapes have been considered to remove above difficulties i.e. Fish and Turtle. Due to higher stability, larger area and greater hydrodynamic efficiency Sea Turtle has been selected, as it can easily overcome the forces like buoyancy, pressure and thrust force. The results extracted from this research shows that the underwater vehicles based on the biological locomotion principle can perform very well than other propeller counterparts. The research concludes with the performance of a working system that validates motion capabilities related to speed, depth and hydrodynamic efficiency which can be further improved by using sophisticated control systems, outer shell and highly integrated processors.

Published: April 2021

We show that string-net models provide a novel geometric method to construct invariants of mapping class group actions. Concretely, we consider string-net models for a modular tensor category C. We show that the datum of a specific commutative symmetric Frobenius algebra in the Drinfeld center Z(C) gives rise to invariant string-nets. The Frobenius algebra has the interpretation of the algebra of bulk fields of the conformal field theory in the Cardy case.
The luring mantid: Protrusible pheromone glands in Stenophylla lobivertex (Mantodea: Acanthopidae)
Authors: Schwarz Christian J. , Glaw Frank
Published: April 2021

The hitherto unknown pheromone gland of femaleStenophylla lobivertexLombardo, 2000, a poorly understood praying mantis distributed in the Neotropics, is described and figured. In contrast to other mantodeans, this species has a protrusible, bifurcated (Y-shaped) gland of 6 mm length. It is protracted by sexually receptive females during nighttime and only when undisturbed. The significance of this morphological and behavioral adaptation is discussed in light of the reproductive strategy of the species and its assumed rarity in the natural habitat.
Influence of migration processes on the demographic development in the Yamal–Nenets Autonomous Okrug
Authors: Pomazkin Dmitry V.
Published: April 2021

The article discusses the influence of migration on the development of demographic processes in the Yamal–Nenets Autonomous Okrug. The study shows that the current level of migration will lead to a decrease in the population due to the uneven sex and age structure of the population of the region. In this context, the author presents estimates of the number and costs of shift workers, that need to be attracted to compensate for the economically active population reduction.
Repeatability vs complexity: kinematic comparison between a dressage simulator and real horses
Authors: Clark L. , Bradley E.J. , Nankervis K. , Ling J.
Published: April 2021

Riding simulators are designed to replicate movement of a horse for the purpose of assessment and training of horse riders, but little is known about their similarity in replicating movement of horses. This study tested the validity of a dressage simulator, by measuring cycle/stride duration, range and symmetry of displacement of the simulator and comparing displacement vectors to that of real horses trotting on a treadmill. A reflective marker was placed on the midline of the simulator at the estimated level of the 18th thoracic vertebrae (T18), and over the T18 spinous process of ten horses. The simulator displacement was recorded in trot mode, while the real horses trotted at a comfortable speed on a treadmill. Displacements in three axes of motion were measured using 10 high-speed video cameras sampling at 240 Hz. Correlation tests showed high levels of statistical repeatability and symmetry of the simulator between multiple runs. Mean cycle/stride duration of the simulator was significantly faster than the group of horses by 0.17 s. Significant differences between the simulator and horses were shown in overall displacement in two axes, the simulator displaying 70% greater displacement in the mediolateral axis, 22% greater displacement in the craniocaudal axis, but displaying 12% less movement in the dorsoventral axis, which was not statistically significant. Displacement trajectories showed similarities in the frontal plane, displaying a butterfly-shaped sequence, but clear differences in the sagittal plane, with the horses showing an oval pattern of displacement and the simulator a clear linear displacement. Caution must therefore be taken with assumptions that riders will move in the same way on a simulator as they would on a real horse.

Published: April 2021

Occurrence of mycotoxins in agricultural products represents a risk for human and animal health. Therefore, there is a requirement of strategies to mitigate their harmful impacts. This study investigated the effects of phytic acid (IP6) on the immunological response of pro-(interleukin (IL)-1β, IL-6, IL-8, IL-10, interferon (IFN)-γ, tumour necrosis factor (TNF)-α) and anti-inflammatory (IL-10) cytokines and β-defensins 1 (pBD-1) and 2 (pBD-2) in porcine jejunal explants exposed to deoxynivalenol (DON) and fumonisin B1 (FB1). The explants were exposed to the following treatments: control, DON (10 μM), DON plus IP6 2.5 mM or 5 mM, FB1 (70 μM), FB1 IP6 plus 2.5 or 5 mM. The expression levels of the cytokines were measured by RT-qPCR. The exposure to FB1 and DON induced intestinal lesions. The presence of 2.5 and 5 mM IP6 inhibited the morphological changes induced by the mycotoxins. The explants exposed to DON showed an increase in the expression of IL-1β and IL-8 and a decrease in the levels of IL-6, IFN-γ, IL-10 and pBD-2. IP6 (5 mM) decreased the expression of IL-8 and increased the expression in pBD-1 and 2 compared to DON alone. FB1 induced a significant decrease in the levels of most of the pro-inflammatory cytokines, IL-10 and pBD-1, and an increase in IL-1β expression. The addition of IP6 5 mM induced significant increase in TNF-α expression compared to FB1. Taken together, the results suggest IP6 modulates immunological changes induced by DON and FB1 on intestinal mucosa resulting in beneficial effects that contribute to intestinal homeostasis and health.

The Real Issues Behind Providing Continuing Education in Nursing
Authors: Welch Deborah
Published: April 2021

No one seriously questions the necessity for continuing education in nursing. The current debate over providing continuing education concerns whether or not it should be made voluntary or mandated by law. But this concern is not the real issue at hand. The real issue concerns the question, why has it been that nursing as a group, has failed to fulfill professional requirements of self-responsibility to attain increased skill and knowledge in an ongoing manner to maintain standards of professional practice? Or what are the obstacles or deterrents to continuing education in nursing, intrinsic and extrinsic to the learner? The problem is multidimentional and involves various aspects of nursing service at the unit, supervisory, and administrative levels. This article outlines some of the contributing factors within three major areas of concern: problems involving nursing leadership, problems involved in the functioning of continuing education departments, and inherent problems within nursing as a group.
Personal Qualities of Nurses Implying Need for Continuing Education to Increase Interpersonal and Leadership Effectiveness*
Authors: Gluck Miriam , Charter Richard
Published: April 2021

Some research indicates that nurses with considerable experience in nursing service are lacking in personal qualities that would promote interpersonal and leadership effectiveness. To study this further, the personal qualities of 80 randomly selected medical and surgical staff nurses were tested using the Cattell 16 Personality Factor Questionnaire. The subjects were placed in five groups according to their years of experience in nursing service and were compared to each other and also to adult female norms. The nurses as a whole scored more towards being reserved, detached, critical, and aloof than being warmhearted and outgoing. Nurses with 21 or more years of nursing experience were less assertive, submissive, more dependent, conforming, docile, and easily led than nurses with less experience. The findings imply a need for continuing education to increase interpersonal and leadership abilities in these identified groups of nurses.

Changing Nurses' AIDS-Related Knowledge and Attitudes Through Continuing Education
Authors: Flaskerud Jacquelyn H , Lewis Mary Ann , Shin Diana
Published: April 2021

ABSTRACT

The purpose of this study was to determine the effects of an acquired immunodeficiency syndrome (AIDS) continuing education conference on nurses' knowledge and attitudes. Subjects in the study (N= 125) were participants in a one-day conference held at a major medical center in southern California. Content of the program included AIDS epidemiology and etiology, infection control, psychosocial and institutional support for health care workers, sexual history taking and counseling, attitudes toward risk behaviors and the major transmission groups, and legal and ethical issues. Subjects were pretested and posttested using a structured questionnaire that measured AIDS-related knowledge and attitudes, and satisfaction with the conference. Participants were re tested 2 to 3 months after the conference. There were significant pretest/posttest differences in knowledge and attitudes that were retained on retest. Subjects with lower levels of knowledge made the greatest gains in knowledge. There was also a tendency for knowledge levels to increase between posttest and retest suggesting that subjects were continuing to learn. Participants indicated satisfaction with the conference speakers and content.
Health Care Workers' Anxieties and Fears Concerning AIDS: A Literature Review
Authors: All Anita
Published: April 2021

ABSTRACT

Acquired immunodeficiency syndrome (AIDS) is a serious illness and a public health crisis that merits the concern of everyone. Three key features make AIDS difficult to control. The first feature is that the disease is predominantly spread sexually. The second feature is that a period of infectivity may last from months to years, and the infected individual may not be aware that he or she is infected. The last feature is that AIDS also may be spread by percutaneous and perinatal transmission. Whatever success public education may have in changing sexual behavior, it will not be seen for several years, and the number of AIDS cases will continue to grow.

The following literature review leads to a prediction that education will have a profound impact on the anxiety connected with providing care for AIDS patients. Education is a powerful tool that can be used by health care workers to change how AIDS is perceived. Health care workers must become aware of their misconceptions, fears, and anxieties about this disease and afflicted individuals.

Compliance With Mandatory Continuing Education in Nursing: A Hospital-Based Study
Authors: DeHaven Madeleine M
Published: April 2021

ABSTRACT

The purpose of this study, which was conducted in a teaching hospital in northern New York, was to evaluate staff nurse and head nurse (HN) compliance with employer mandated continuing education (CE). The hospital's CE policy for nurses required all nursing employees to attend any six CE or inservice education programs per evaluation year. Staff nurse and HN sample groups were studied. The results revealed that 79% of the staff RN sample and 100% of the HN sample complied with employer requirements.

The staff RNs attended an average of 13 programs per year, and the HNs averaged 16 programs per year. When comparing these averages to the actual number required, the assumption can be made that nurses attend CE programs for reasons other than complying with requirements.

Published: April 2021

ABSTRACT

The purpose of this study was to determine differences in nurse attitude and clinical practice following a foot care education program. In a survey completed after the program, 23 nurses reported that they had less difficulty touching a smelly foot (p<.02), that they would be less bothered by a foot with an odor (p<.03), that they would have less difficulty touching an unsightly foot depicted in a slide (p<.03), and that they felt less anger at patients who don't follow recommendations (p<.03). The nurses also expressed more belief that patients quickly forget important information (p<.03) and that if patients knew the effects of their poor health habits they would change (p<.02). Ninety-one percent of the RN sample reported that their foot assessment and care practices had changed as a result of the program.

An Educational Fair and Poster Approach to Organization-Wide Mandatory Education
Authors: Thurber Raymond F , Asselin Marilyn E
Published: April 2021

ABSTRACT

Background: An educational fair and poster approach was developed to meet organizationwide mandatory education requirements.

Method: A multidisciplinary task force identified 25 mandatory topics. Task force members utilized posters to indicate key points (principles) and questions for each topic. Two interactive stations, body mechanics and fire safety, were developed to allow staff to actively participate and obtain immediate feedback on competency. This educational activity was presented in a fair-like atmosphere continuously over 3 days to reach a majority of staff.

Results: Ninety-three percent of the staff attended the educational activity. Department directors received immediate feedback on attendance, test scores, evaluation summaries and problem areas. Post-fair evaluation comments from department directors and staff were very positive. There was a major savings in both staff and staff development work hours.

Conclusion: An educational fair and poster approach is an efficient method of providing organization-wide mandatory education. This approach can be adapted easily to any organization.
Divergent Backgrounds, Unified Goals: Continuing Education Program for Multinational Nurses in a Hospital in the Middle East
Authors: Adejumo Oluyinka
Published: April 2021

ABSTRACT

This article reports continuing education as one strategy used to resolve the competence issues of multinational nurses working in Saudi Arabia. Four categories of Staff Nurses (I, II, III, and IV), N = 111, recruited from eight countries participated in a study that describes the outcomes of a training session for nurses at one hospital in Dammam. An average of 12 to 13 nurses attended 1-day courses over a 9-day period to address urgent policies and procedures selected from the hospital's guidelines for patient care. Results from pretests and posttests completed by the participants yielded information that echo differences of the nurses in terms of country of origin and possibly educational background, rather than their recruitment status with which the employers determine remuneration and responsibilities. The findings suggest ways to ensure that future nurses derive more benefit, and that recruiters and employers reconsider the criteria used for recruitment and placement.
Continuing Education Outcomes Related to Pain Management Practice
Authors: Czurylo Kathryn , Gattuso Michelle , Epsom Rita , Ryan Catherine , Stark Barbara
Published: April 2021

ABSTRACT

Background: Nursing practice outcomes of continuing education need to be measured and reported as one indicator of the value of nursing continuing education. This article makes the case that knowledge gain, the traditional measure of continuing education effectiveness, is not necessarily sufficient to assess changes in nursing practice.

Method: A pretest/posttest design was used to measure nursing practice outcomes of a continuing education program about pain management. A total of 50 attendees returned both the pretests and posttests and 68 attendees returned the follow-up evaluation.

Results: Ninety-four percent of the respondents had improved scores on the posttest. Ninety-one percent of the follow-up evaluation respondents stated they had an opportunity to use the new information and 98% stated the use of this information has improved patient care.

Conclusion: This study found that a continuing education program triggered practice changes. The results of this study correlate with previous research that supports the need for practice outcome measurements.

Authors: Waddell Janice , Durrant Michele , Avery Shirley
Published: April 2021

ABSTRACT

Background: This article describes how nurse educators at The Hospital for Sick Children, Toronto, have used Benner's findings as a framework to direct the advancement of professional development programs, specifically preceptorship, orientation, and central education programs.

Method: Narrative methodology was introduced as a key educational strategy to capture the complexity of pediatric clinical practice and enhance learning experiences.

Results: The shift in content and structure of the education programs from a structured behavioral teaching-learning framework to the use of narrative methodology has enhanced learning, professional development and clinical practice.

Conclusion: Participant evaluations of these programs suggest a high level of satisfaction with the use of narrative methodology. Evaluative measures focusing on the relationship between narrative methodology, professional development, and client outcomes is needed. This evaluative approach that measures outcomes is imperative to future directions in program planning.

THE NOILES HINGE KNEE PROSTHESIS WITH AXIAL ROTATION
Authors: Flynn Leo M
Published: April 2021

ABSTRACT: The Noiles total knee prosthesis is a constrained knee which provides free axial rotation of the tibia. Because it does not have a fixed coupling between the femur and the tibia, the prosthesis greatly reduces the transmission of torsional forces to the prosthesis-cement-bone interface. The possibility of prosthetic loosening, sometimes caused by forces generated during full flexion in a conventional hinge prosthesis, is significantly reduced. This knee replacement is indicated in severe rheumatoid and degenerative arthritis of the knee joint, severe instability or failure of a previous prosthesis. The prosthesis provides sturdy mechanical support with high load carrying capability, low friction and low wear. Forty arthritis patients with at least 18 months follow up will be discussed. The average preoperative knee evaluation was 30 points on the knee scale, and the average postoperative knee evaluation was 90 points on the knee scale. Surgical technique, advantages and complications will also be discussed.

Twenty Years Experience in Fracture Healing Measurement with Strain Gauges
Authors: Burny F , Donkerwolcke M , Bourgois R , Domb M , Saric O
Published: April 2021

ABSTRACT: The external fixator provides a mechanical connection between the bone fragments and recording devices or power systems. We have used this characteristic of external fixation since 1965 to record deformations occurring at the fracture site and to measure the mechanical characteristics of fracture healing in more than 500 patients. As in all osteosyntheses, the fixation material (here the external rod) resists the mechanical forces applied to the bone fragments. As healing progresses, the bone participates more and more in the weight bearing of the system and the rod deforms less. Seven types of deformation curves have been defined, characterizing seven different modes of healing: 1) normal healing, 2) slow healing, 3) delayed union, 4) arrest in evolution, 5) pseudarthrosis, 6) resorption of the callus, and 7) breakage of the callus.

Early Fitting of the Below Knee Amputee
Authors: Mooney Vert , McClellan Bruce , Cummings Donald , Smith Patti
Published: April 2021

ABSTRACT: A comparison was made of the rehabilitation of patients undergoing below knee amputation during the calendar year 1982 on the orthopedic, general, and vascular surgical services at Parkland Hospital. Eight of nine trauma patients on the orthopedic service were fit with a temporary prosthesis and subsequently were fitted with a definitive prosthesis. Of the remaining 53 patients, only three were fitted with a temporary prosthesis and eventually 13 were fit with a definitive prosthesis. This experience identified a need for an alternative fitting method, which resulted in the design of a temporary, adjustable below knee prosthesis intended to be useful for a significant portion of the below knee population. Thus early ambulation is encouraged, possibly resulting in a higher percentage of successful ambulators. Gratifying early results with eight patients are described.

The most common cause of delay in prosthetic use was financial.
Surgical Technique and Results of Limb Sparing Surgery for High Grade Bone Sarcomas of the Knee and Shoulder
Authors: Malawer Martin
Published: April 2021

ABSTRACT: Thirty-three patients with high grade bone sarcomas of the knee and shoulder treated by limb sparing surgery were evaluated. The histological diagnoses were osteosarcoma (25), chondrosarcoma (3), malignant fibrohistiocytoma (3), fibrosarcoma (1) and unclassified (1). The Surgical Stages were: Stage HA (3), Stage MB (28) and Stage III (3). The operative procedure consisted of three phases: tumor resection, skeletal reconstruction and soft tissue reconstruction. All resections obtained negative margins and were classified as, marginal excision (3), intracompartmental resections (28) and radical resections (2). Overall survival was 77%. Four of 33 patients (12.4%) required a secondary amputation. Local recurrence was 6% (2/33) with an average follow-up of 37.2 months. The most common complications were flap necrosis (33%) and transient nerve palsies (33%). There were 2 infections and one prosthetic dislocation. We believe that limb salvage surgery for high grade bone sarcomas need not be reserved for only those without extraosseous extension. Careful preoperative selection and attention to the three stages of a limb sparing procedure are important for a successful outcome. Presently, we consider the following as contraindications to resection: vascular involvement, pathologic fracture, inappropriate biopsy and infection.

Body loading on Atrophied Bone and Bone Mineral Content: An Experimental Study in the Rabbit
Authors: Laftman Peter , Strömberg Lennart
Published: April 2021

ABSTRACT: The quality of a cortical bone, as reflected in the bone mineral content, has been studied in rabbit tibiae during an experimental atrophy process, and following recovery and adaptation to increased loading. Atrophy of the bone was induced by a rigid internal fixation plate applied to the tibia for 12 weeks. During the process of recovery after the plate had been removed, the bone mineral content was studied by means of an ashing procedure. The bone mineral content per unit volume cortical bone remained unchanged both at maximum atrophy and during the subsequent process of recovery.
The Efficacy of Intraoperative Autologous Transfusion in Major Orthopedic Surgery: A Regression Analysis
Authors: Bovill David F , Moulton Charles W , Jackson William S T , Jensen J Kenneth , Barcellos Robert W
Published: April 2021

ABSTRACT: Perioperative blood loss associated with 89 cases of major orthopedic surgery was compared with that of a control group of 89 to determine the effectiveness of intraoperative autologous transfusion. Volume of banked blood transfused and hematocrit change were used to determine total blood loss. The orthopedic cases consisted of cemented "virgin" total hip replacement, cemented virgin tricompartmental knee replacement, and spine fusion. Use of an autotransfusion device (Cell Saver) intraoperatively was associated with significantly smaller volumes of transfused banked blood and significantly smaller hematocrit drops in the groups of patients who underwent total hip replacement or spine fusion, but not in the group of patients who underwent total knee replacement. One potential source of bias in the study stems from the fact that four days were allotted for equilibrium from perioperative blood loss in the hip and knee replacement groups, while, for reasons of data availability, equilibrium time in the spine fusion groups was two days.
Historical Update and New Developments on the EMG-Force Relationships of Skeletal Muscles

Published: April 2021

ABSTRACT: The EMG-force relationships of skeletal muscles are of significant interest to the orthopedic-biomechanics researcher and have been a topic of interest and controversy for the last three decades. We present the developments reported in the literature, from the early 1950s, relevant to this topic, outlining the details of the controversy and providing additional new information resulting from recent studies.

New data clearly illustrate that the EMG-force relationships are dependent on the firing rate and recruitment control strategy used by a muscle. Muscles that use motor unit recruitment to obtain the initial 50% of their maximal force, and use firing rate increase to complement the remaining 50%, have a nearly linear EMG-force relationship. Muscles that use recruitment to obtain 60% and up to 100% of their maximal force demonstrate progressive increase in non-linearity of their EMG-force curves.

A clear warning is issued against the indiscriminate use of EMG as a representative of muscle force. The recruitment pattern of the muscle under consideration should first be obtained in such a way that the appropriate EMG-force curve is selected.

Primary Osteogenic Sarcoma of the Clavicle: A Case Report
Authors: Byrd Thomas , Gleis Gregory E , Johnson John R
Published: April 2021

ABSTRACT: The clavicle is an unusual site for any primary bone tumor, including osteogenic sarcoma. A paucity of data in the literature on this type of lesion makes clear understanding of the optimal treatment difficult. Given its anatomical location, the lesion requires a multidisciplinary approach for optimal care, with each member of the health care team being important for maintaining and prolonging the quality of life for a patient.

A 22-year-old man with primary osteogenic sarcoma of the clavicle was treated with preoperative and postoperative chemotherapy and was managed with surgical excision of the tumor while sparing the limb. Clinically disease-free for 20 months postoperatively, the patient presented with gross evidence of local recurrence with diffuse metastatic involvement at 22 months and died 6 weeks later. We have found no report of long-term survival on a patient with this lesion.
Total Ankle Arthroplasty Using Biological Fixation Components Compared to Ankle Arthrodesis
Authors: Scholz Kenneth C
Published: April 2021

ABSTRACT: When conservative measures fail to alleviate pain and disability of ankle joint disease, tibiotalar arthrodesis is the present accepted surgical treatment. Unfortunately, ankle arthrodesis also carries a significant rate of complications and the success rate does not parallel the results of hip and knee joint arthroplasties. A large percentage of ankle arthrodeses remain painful, and function is not normal. There is no satisfactory "salvage procedure" to a painful ankle fusion. Patients with primary ankle arthritis tend to develop bilateral ankle involvement as well as involvement of the subtalar and midtarsal joints; bilateral ankle fusion results in a severe handicap to gait and function. Ankle fusion with involvement of the subtalar or midtarsal joints might well result in a painful fusion. Maintenance of tibiotalar motion appears essential in both instances. It is apparent that all ankle problems cannot be dealt with by fusion and a successful long-term ankle arthroplasty is needed. Total ankle arthroplasty using cement fixation remains controversial. Continued use of polymethylmethacrylate and additional design changes do not appear to be the answer to possible ankle joint replacement. Initial success using the PCA ™ concept of biological cementless fixation of the Scholz total ankle prosthetic components appears to offer a new dimension in the success of total ankle arthroplasty.
Aspects of the Microbe: Host Relationship in Staphylococcal Hematogenous Osteomyelitis
Authors: Gillespie William J , Haywood-Farmer Mary , Fong Ray , Harding Susan M
Published: April 2021

ABSTRACT: Nasal carriage of staphylococci, and some in vitro tests of host antimicrobial defense were studied in a group of children who had recovered from staphylococcal hematogenous osteomyelitis at least one year previously. The same studies were carried out in a group of first degree relatives, and in age- and sex-matched controls. Nasal carriage was significantly more common (P = .039) in these children than in age- and sex-matched controls, and commoner (P =.19) in the first degree relatives than in controls.

Total immunoglobulin G (IgG) levels were significantly lower in the children studied than in controls (P = .022), and in relatives than in controls (P = .032), but the levels remained within an accepted normal range. IgG levels were also significantly lower in carriers of Staphylococcus aureus than in non carriers (P = .033).

Other immunoglobulin levels, complement levels, leukocyte phagocytic and killing power, leukocyte Chemotaxis, and leukocyte migration inhibition, were indistinguishable between the children, their relatives, and controls. No statistically significant association between histocompatibility antigen profile and previous history of osteomyelitis, or nasal carriage of staphylococci, was found. More detailed studies are required to confirm and clarify the associations.

A Safe, Pre-Fabricated, Immediate Postoperative Prosthetic Limb System for Rehabilitation of Below-Knee Amputations
Authors: Pinzur Michael S , Littooy Fred , Osterman Helen , Schwartz David
Published: April 2021

ABSTRACT: Thirty-eight below-knee amputees were treated with a commercially available pneumatic prosthetic limb system, applied immediately postoperatively, that would allow immediate weight bearing following lower extremity amputation. Thirty-four limbs were amputated for peripheral vascular insufficiency and four were amputated due to trauma. Weight bearing was initiated an average of 4.7 days following surgery and patients were discharged with a non-removable temporary prosthesis at an average of 8.9 days. Thirty-three healed and were uneventfully fit with standard below-knee prosthetic limbs. Three required revision to the above-knee level. In a controlled setting, early weight bearing in the peripheral vascular insufficiency patient can be initiated with a low risk of local wound complication.
The Use of Indium-111 Labeled Platelet Scanning for the Detection of Asymptomatic Deep Venous Thrombosis in a High Risk Population

Published: April 2021

ABSTRACT: Five hundred indium-111 labeled platelet imaging studies (387 donor and 1 1 3 autologous) were performed postoperatively in 473 patients who had undergone total hip replacement, total knee replacement, or internal fixation of a hip fracture to detect occult deep venous thrombosis. All patients had been anticoagulated prophylactically with aspirin, warfarin sodium (Coumadin), or dextran. Thirty-four possible cases of proximal deep venous thrombosis were identified in 28 asymptomatic patients. To verify the scan results, 31 venograms were performed in 25 patients (three refused). In 21 of 31 cases, totally occlusive thrombi were detected; in 5 cases, partially occlusive thrombi were detected; in 5 cases, no thrombus was seen. No patient who had a negative scan nor any patient who had a verified positive scan (and received appropriate heparin therapy) subsequently developed symptoms or signs of pulmonary embolism. One hundred forty-one indium study patients also underwent Doppler ultrasonography/impedance plethysmography (Doppler/IPG) as a comparative noninvasive technique. In 137 cases, the results of the indium study and Doppler/IPG studies were congruent. The indium study had no false negative results that were detected by Doppler/IPG. No patient had any clinically evident toxicity. These results suggest that indium-111 labeled platelet scanning is a safe, noninvasive means for identifying DVT in high risk patients.
