Exploring cultural sensitivity during distance simulations in pediatric emergency medicine

Background

Cultural sensitivity (CS) training is vital to pediatric emergency medicine (PEM) curricula. This study aimed to explore CS in Yale PEM fellows and emergency medicine (EM) residents at Indus Hospital and Health Network (IHHN) in Pakistan through distance simulation activities.

Methods

This mixed-methods analysis of an educational intervention was conducted at Yale University in collaboration with IHHN. We approached seven U.S. PEM fellows and 22 Pakistani EM residents. We performed a baseline CS assessment using the Clinical Cultural Competency Questionnaire (CCCQ). Afterward, the U.S. PEM fellows facilitated the Pakistani EM residents through six distance simulation sessions. Qualitative data were collected through online focus groups. The CCCQ was analyzed using descriptive statistics, and content analysis was used to analyze the data from the focus groups.

Results

Seven U.S. PEM fellows and 18 of 22 Pakistani EM residents responded to the CCCQ at the beginning of the module. The mean (±SD) CCCQ domain scores for the U.S. PEM fellows versus the Pakistani EM residents were 2.56 (±0.37) versus 2.87 (±0.72) for knowledge, 3.02 (±0.41) versus 3.33 (±0.71) for skill, 2.86 (±0.32) versus 3.17 (±0.73) for encounter/situation, and 3.80 (±0.30) versus 3.47 (±0.47) for attitude (each out of 5 points). Our qualitative data analysis showed that intercultural interactions were valuable. There is a common language of medicine among the U.S. PEM fellows and Pakistani EM residents. The data also highlighted a power distance between the facilitators and learners, as the United States was seen as the standard of "how to practice PEM." The challenges identified were time differences, cultural practices such as prayer times, the internet, and technology. The use of local language during debriefing was perceived to enhance engagement.

Conclusion

The distance simulation involving U.S. PEM fellows and Pakistani EM residents was an effective approach in assessing various aspects of intercultural education, such as language barriers, technical challenges, and religious considerations.

"I think to myself 'why now?'" - a qualitative study about endometriosis and pain in Austria

BACKGROUND

Endometriosis is a chronic, benign, and oestrogen-dependent condition and about 10-15% of all women of reproductive age are affected by endometriosis worldwide. It is not curable and pain is one of the most common symptoms of endometriosis and leads to low quality of life in affected women. To our knowledge, in German-speaking countries, no studies with qualitative methods approaches are available concerning women who suffer from pain caused by endometriosis and possible associated coping strategies. Our study aims to familiarise ourselves with the individual pain experience of selected women who suffer from endometriosis in Austria and their coping strategies.

METHODS

A qualitative study design was based on problem-centred interviews for data collection and qualitative content analysis for data analysis. The research participants were women aged between 18 and 55 diagnosed with endometriosis and living in Austria. The interview period was from 27 February to 26 March 2019 and interviews lasted between 50 and 75 min.

RESULTS

Eight categories were formulated, of which category 3 (thoughts and feelings regarding endometriosis and pain - 'why?'), category 5 (effects and changes caused by endometriosis and pain - 'quality of life'), category 7 (taboos - 'don`t talk about it'), and category 8 (talking about it - 'contact with others in the same position') were relevant for this article. The remaining four categories [1-4] have already been published elsewhere.

CONCLUSION

Our data show that the social environment plays a fundamental role in coping strategies concerning pain caused by endometriosis. Women in our study reported that exchange with peers offers support. This opens a door for information events, patient organizations like support groups, and the inclusion of these in the supporting system. Involving occupational medicine and workplace health promotion departments in companies should be further goals to support affected women.

Fracture dislocation of the humerus with intrathoracic humeral head fragment - A case report and review of the literature

We present a rare case of humeral fracture dislocation with intrathoracic humeral head fragment. A 74-year old female was transferred to a major trauma facility after falling on her arm while gardening. An intrathoracic humeral head fragment was diagnosed after initial imaging. In correspondence with the department of thoracic surgery, the decision was made to remove the intrathoracic fragment thoracoscopically and succeed with a reverse total shoulder arthroplasty.

“A little monster inside me that comes out now and again”: endometriosis and pain in Austria

Abstract: The topics of endometriosis and pain imply far-reaching problems for women’s health. Using a qualitative research approach, this paper addresses the subjective experience and effects of pain, the methods for dealing with these issues, and the needs of affected women in Austria. Data were collected by problem-focused interviews conducted with ten women suffering from endometriosis, which were later transcribed and subjected to qualitative content analysis. Findings are therefore described using content-related categories. Results show that negative thoughts and feelings like fear, despair, and anger are associated with endometriosis and pain. Moreover, predominantly negative impacts and changes are found in various areas of life, such as the well-being and psyche of those affected, their attitude towards life in general, partnerships, social life, leisure time and work-life balance. In dealing with endometriosis and pain, both Western biomedicine and complementary medicine treatments are used. Support from one’s inner circle of friends and exchange and interaction with others affected by the disease are seen to be invaluable. Attending physicians as well as patients themselves and their private, social, and working environment should encourage open communication about endometriosis and the related pain.

Seven ways to get a grip on implementing Competency-Based Medical Education at the program level

Competency-based medical education (CBME) curricula are becoming increasingly common in graduate medical education. Put simply, CBME is focused on educational outcomes, is independent of methods and time, and is composed of achievable competencies.¹ In spite of widespread uptake, there remains much to learn about implementing CBME at the program level. Leveraging the collective experience of program leaders at Queen's University, where CBME simultaneously launched across 29 specialty programs in 2017, this paper leverages change management theory to provide a short summary of how program leaders can navigate the successful preparation, launch, and initial implementation of CBME within their residency programs.

A systems genomics approach identifies SIGLEC15 as a susceptibility factor in recurrent vulvovaginal candidiasis

Candida vaginitis is a frequent clinical diagnosis with up to 8% of women experiencing recurrent vulvovaginal candidiasis (RVVC) globally. RVVC is characterized by at least three episodes per year. Most patients with RVVC lack known risk factors, suggesting a role for genetic risk factors in this condition. Through integration of genomic approaches and immunological studies in two independent cohorts of patients with RVVC and healthy individuals, we identified genes and cellular processes that contribute to the pathogenesis of RVVC, including cellular morphogenesis and metabolism, and cellular adhesion. We further identified SIGLEC15, a lectin expressed by various immune cells that binds sialic acid-containing structures, as a candidate gene involved in RVVC susceptibility. Candida stimulation induced SIGLEC15 expression in human peripheral blood mononuclear cells (PBMCs) and a polymorphism in the SIGLEC15 gene that was associated with RVVC in the patient cohorts led to an altered cytokine profile after PBMC stimulation. The same polymorphism led to an increase in IL1B and NLRP3 expression after Candida stimulation in HeLa cells in vitro. Last, Siglec15 expression was induced by Candida at the vaginal surface of mice, where in vivo silencing of Siglec15 led to an increase in the fungal burden. Siglec15 silencing was additionally accompanied by an increase in polymorphonuclear leukocytes during the course of infection. Identification of these pathways and cellular processes contributes to a better understanding of RVVC and may open new therapeutic avenues.

Assessing selection signatures within and between selected lines of dual-purpose black and white and German Holstein cattle

The aim of this study was to detect selection signatures considering cows from the German Holstein (GH) and the local dual-purpose black and white (DSN) population, as well as from generated sub-populations. The 4654 GH and 261 DSN cows were genotyped with the BovineSNP50 Genotyping BeadChip. The geographical herd location was used as an environmental descriptor to create the East-DSN and West-DSN sub-populations. In addition, two further sub-populations of GH cows were generated, using the extreme values for solutions of residual effects of cows for the claw disorder dermatitis digitalis. These groups represented the most susceptible and most resistant cows. We used cross-population extended haplotype homozygosity methodology (XP-EHH) to identify the most recent selection signatures. Furthermore, we calculated Wright's fixation index (F_ST ). Chromosomal segments for the top 0.1 percentile of negative or positive XP-EHH scores were studied in detail. For gene annotations, we used the Ensembl database and we considered a window of 250 kbp downstream and upstream of each core SNP corresponding to peaks of XP-EHH. In addition, functional interactions among potential candidate genes were inferred via gene network analyses. The most outstanding XP-EHH score was on chromosome 12 (at 77.34 Mb) for DSN and on chromosome 20 (at 36.29-38.42 Mb) for GH. Selection signature locations harbored QTL for several economically important milk and meat quality traits, reflecting the different breeding goals for GH and DSN. The average F_ST value between GH and DSN was quite low (0.068), indicating shared founders. For group stratifications according to cow health, several identified potential candidate genes influence disease resistance, especially to dermatitis digitalis.

[Primary fracture protheses and reverse shoulder arthroplasty in complex humeral head fractures : An alternative to joint-preserving osteosynthesis?]

BACKGROUND

The surgical management of complex humeral head fractures has adapted dynamically over the course of the last decade. The primary use of reverse shoulder arthroplasty in elderly patients has gained in relevance due to promising short and middle-term results. Long-term results, however, are still pending. The appliance of anatomical hemiarthroplasty, on the other hand, has lost in significance in favour of osteosynthesis and reverse shoulder arthroplasty.

INDICATIONS

This review article follows the question as to under which circumstances primary fracture arthroplasty reflects an alternative or even a preference to joint-preserving osteosynthesis in the treatment of complex proximal humeral fractures. It also specifies spectrums of indications for anatomical hemiarthroplasty and reverse shoulder arthroplasty.

A novel mutation in the TG gene (G2322S) causing congenital hypothyroidism in a Sudanese family: a case report

Background

Congenital hypothyroidism (CH) has an incidence of approximately 1:3000, but only 15% have mutations in the thyroid hormone synthesis pathways. Genetic analysis allows for the precise diagnosis.

Case presentation

A 3-week old girl presented with a large goiter, serum TSH > 100 mIU/L (reference range: 0.7–5.9 mIU/L); free T₄ < 3.2 pmol/L (reference range: 8.7–16 pmol/L); thyroglobulin (TG) 101 μg/L. Thyroid Tc-99 m scan showed increased radiotracer uptake. One brother had CH and both affected siblings have been clinically and biochemically euthyroid on levothyroxine replacement. Another sibling had normal thyroid function. Both Sudanese parents reported non-consanguinity. Peripheral blood DNA from the proposita was subjected to whole exome sequencing (WES). WES identified a novel homozygous missense mutation of the TG gene: c.7021G > A, p.Gly2322Ser, which was subsequently confirmed by Sanger sequencing and present in one allele of both parents. DNA samples from 354 alleles in four Sudanese ethnic groups (Nilotes, Darfurians, Nuba, and Halfawien) failed to demonstrate the presence of the mutant allele. Haplotyping showed a 1.71 centiMorgans stretch of homozygosity in the TG locus suggesting that this mutation occurred identical by descent and the possibility of common ancestry of the parents. The mutation is located in the cholinesterase-like (ChEL) domain of TG.

Conclusions

A novel rare missense mutation in the TG gene was identified. The ChEL domain is critical for protein folding and patients with CH due to misfolded TG may present without low serum TG despite the TG gene mutations.

[Prosthesis replacement in periprosthetic humeral fractures]

OBJECTIVE

Stabilization of the humerus with preservation or restoration of the shoulder function.

INDICATIONS

Always in the presence of a loose prosthesis. It may become necessary in conditions of poor bone stock and if osteosynthesis is not possible.

CONTRAINDICATIONS

Noncompliant patients due to alcohol or drugs. Local infections.

SURGICAL TECHNIQUE

The loose implant is removed using an extended anterior deltopectoral approach. After exploration of the fracture and extended soft tissue release, the glenoidal components are implanted with visualization and protection of the axillary nerve. A long stemmed implant is typically needed on the humeral side. It is anchored in the distal fragment over a length of about 6 cm. Soft tissue tension is crucial, especially with reverse shoulder arthroplasty.

POSTOPERATIVE MANAGEMENT

Postoperatively, the affected limb is immobilized for 6 weeks on a 15° shoulder abduction pillow with active assisted movement therapy up to the horizontal plane. This is followed by gradual pain-adapted increases of movement, muscle coordination, and strength.

RESULTS

In 17 patients with periprosthetic fractures of the humerus surgically treated in our institution, 4 underwent revision arthroplasty because of a loose prosthesis. No intra- or postoperative complications were observed. All fractures healed except one.

Introduction of the Abbreviated Westmead Post-Traumatic Amnesia Scale and Impact on Length of Stay

Background and Aims:

Mild traumatic brain injury is a common presentation to Emergency Departments. Early identification of patients with cognitive deficits and provision of discharge advice are important. The Abbreviated Westmead Post-traumatic Amnesia Scale provides an early and efficient assessment of post-traumatic amnesia for patients with mild traumatic brain injuries, compared with the previously used assessment, the Modified Oxford Post-traumatic Scale.

Material and Methods:

This retrospective cohort study reviewed 270 patients with mild traumatic brain injury assessed for post-traumatic amnesia over a 2-year period between February 2011 and February 2013. It identified those assessed with Abbreviated Westmead Post-traumatic Amnesia Scale versus Modified Oxford Post-traumatic Scale, the outcomes of these post-traumatic amnesia assessments, the hospital length of stay for patients, and their readmission rates.

Results:

The Abbreviated Westmead Post-traumatic Amnesia Scale was used in 91% of patient cases (and the Modified Oxford Post-traumatic Scale in 7%), and of those assessed with the Abbreviated Westmead Post-traumatic Amnesia Scale, 94% cleared post-traumatic amnesia testing within 4 h. Of those assessed with the Abbreviated Westmead Post-traumatic Amnesia Scale, 56% had a shorter length of stay than had they been assessed with the Modified Oxford Post-traumatic Scale, resulting in 295 bed-days saved. Verbal and written discharge advice was provided to those assessed for post-traumatic amnesia to assist their recovery. In all, 1% of patients were readmitted for monitoring of mild post-concussion symptoms.

Conclusion:

The Abbreviated Westmead Post-traumatic Amnesia Scale provides an effective and timely assessment of post-traumatic amnesia for patients presenting to the Emergency Department with mild traumatic brain injury compared with the previously used assessment tool. It helps identify patients with cognitive impairment and the need for admission and further investigation, resulting in appropriate access to care. It also results in a decreased length of stay and decreased hospital admissions, with subsequent cost savings to the hospital.

A Pilot Study Using Preoperative Cerebral Tissue Oxygen Saturation to Stratify Cardiovascular Risk in Major Non-Cardiac Surgery

This prospective pilot study evaluated whether low preoperative cerebral tissue oxygen saturation is associated with unfavourable outcomes after major elective non-cardiac surgery. Eighty-one patients over 60 years of age, American Society of Anesthesiologists physical status 3 or 4, were recruited. Resting cerebral tissue oxygen saturation was recorded on room air, and after oxygen supplementation, using cerebral oximetry. The primary outcome was 30-day major adverse event of combined mortality or severe morbidity, and the secondary outcome was 30-day new disability. Eleven patients (13.6%) suffered a major adverse event, and 28 patients (34.6%) experienced new disability. Room air cerebral tissue oxygen saturation was significantly different between patients who had a major adverse event, 67% (95% confidence interval [CI] 65–70) versus unaffected, 71% (95% CI 70–72; P=0.04). No statistical difference was found between patients for new disability (range 70%– 74%; P=0.73). Room air cerebral tissue oxygen saturation was significantly associated with major adverse events (odds ratio 1.36 (95% CI 1.03–1.79), P=0.03). Saturation levels ≤68% carried a positive likelihood ratio of 2.2 for death or severe morbidity, P=0.04. A definitive trial is required to confirm if cerebral oximetry can be used to stratify the cardiovascular risk of patients presenting for non-cardiac surgery.

[Arthroscopic subacromial decompression]

OBJECTIVE

Coracoacromial ligament release to widen the subacromial space, resection of the anterior undersurface of the acromion and, if needed, caudal exophytes at the acromioclavicular joint.

INDICATIONS

All types of outlet impingement after 3 months of conservative treatment.

CONTRAINDICATIONS

Impingement syndrome with instability/muscular imbalance, massive rotator cuff tear, unstable os acromionale, posterior-superior impingement, joint infection, freezing phase of a secondary frozen shoulder.

SURGICAL TECHNIQUE

Lateral decubitus position with traction device for the arm. Diagnostic arthroscopy of the glenohumeral joint via standard portals. With arthroscope moved to the subacromial space, bursectomy, electrosurgical release of coracoacromial ligament, resection of acromial hook through standard posterior portal.

POSTOPERATIVE MANAGEMENT

Physiotherapy or self-exercises on postoperative day 1, pain-adapted analgesia to avoid shoulder stiffness.

RESULTS

Several studies present positive long-term results compared to conservative treatment (and open acromioplasty) for partial rotator cuff tears and for elderly patients. With a 20-year follow-up, successful results have been achieved for all patients with isolated impingement syndrome.

Association of a variable number tandem repeat in the NLRP3 gene in women with susceptibility to RVVC

Vaginal infections with Candida spp. frequently occur in women of childbearing age. A small proportion of these women experience recurrent vulvovaginal candidosis (RVVC), which is characterized by at least three episodes of infection in one year. In addition to known risk factors such as antibiotics, diabetes, or pregnancy, host genetic variation and inflammatory pathways such as the IL-1/Th17 axis have been reported to play a substantial role in the pathogenesis of RVVC. In this study, we assessed a variable number tandem repeat (VNTR) polymorphism in the NLRP3 gene that encodes a component of the inflammasome, processing the proinflammatory cytokines IL-1β and IL-18. A total of 270 RVVC patients and 583 healthy controls were analyzed, and increased diseases susceptibility was associated with the presence of the 12/9 genotype. Furthermore, functional studies demonstrate that IL-1β production at the vaginal surface is higher in RVVC patients bearing the 12/9 genotype compared to controls, whereas IL-1Ra levels were decreased and IL-18 levels remained unchanged. These findings suggest that IL-1β-mediated hyperinflammation conveyed by the NLRP3 gene plays a causal role in the pathogenesis of RVVC and may identify this pathway as a potential therapeutic target in the disease.

Non-Union in Upper Limb Fractures - Clinical Evaluation and Treatment Options

Although non-unions in the upper limb are rare different treatment options of this challenging situation are still affected with up to 20% of failure rate due to current literature. Risk factors for delayed and non-union of fractures are mainly the size of the fracture gap and bone loss of open fractures or in primary surgery followed by other relevant internal and external factors. In the upper limb non-unions of long bones are described with up to 30% after operative intervention. Especially in the upper limb range of motion is limited in non-union cases and disables adjacent joints like the shoulder, elbow and wrist hence reducing the total activity level of affected patients. Beside careful investigation of the causes leading to the non-union a comprehensive treatment plan should be defined to achieve successful results. Treatment can be non-operative in several, selected cases, but in the majority of cases revision surgery is necessary to achieve osseous healing. Our own experience showed that non-union in the upper limb are rare and account for only 1.7% of all surgical managed upper limb fractures. Non-union of upper limb fractures occur most frequently in clavicle fractures followed by humeral fractures. Atrophic non-union is the most frequent reason for osseous non-union (57%) and osseous healing after revision surgery in non-unions is completed after a mean of 6.45 months. This article will give a brief overview of the genesis, clinical evaluation, treatment options and recommendations in upper limb non-unions according to the current literature. Key words: fracture, upper-limb, non-union, osteosynthesis, cancellous bone-graft.
