RESUMEN
Desmoplastic fibroma (DF) is an uncommon bone tumor that originates from the mesenchymal tissue and despite being benign, exhibits aggressive behavior locally. The following report describes the case of a 7-year-old boy with a rapidly enlarging swelling on the right side of the mandible. After a thorough clinical examination, radiographic imaging, and histopathological analysis, the diagnosis of DF was confirmed. Treatment planning was formulated considering both the tumor's tendency for local recurrence and the patient's well-being. Due to the patient's young age, segmental resection was not deemed appropriate, and an aggressive curettage and enucleation of the lesion followed by the bone graft was performed instead. The patient was kept under close follow-up for the first month of post-surgery and later reviewed after 3, 6, 9, and 12 months, respectively. Good bone healing was observed on radiographs. The patient did not show any signs of recurrence based on clinical or radiographic assessments and did not exhibit any neurosensory deficits as well.

OBJECTIVES: The present systematic review was conducted to give an overview of toothbrush contamination among the general population and the factors affecting toothbrush contamination with an evidence-based approach. DATA/SOURCES: Medline (Pub Med), CINAHL Plus, Cochrane Library and Dentistry and Oral Health Sciences Source were searched for the results after applying the search strategy from January 2012 to May 2022, following inclusion and exclusion criteria. The data were collected using a self-made data collection form on study characteristics, population attributes and the main features, including the study's outcomes. The methodological quality of the included studies was independently evaluated based on the Joanna Briggs Institute's (JBI) critical appraisal checklist for cross-sectional studies and the Risk of Biasness Tool-1 (Rob-1) for randomized controlled trials (RCTs). A descriptive analysis of the included studies was done using SWiM guidelines. The impact of charcoal and non-charcoal brushes on toothbrush disinfection was quantitatively analysed using a forest plot. STUDY SELECTION: Of the 687 studies screened by title and abstract, 27 articles were selected for full-text evaluation using the EndNote reference program (Ver. X9.2). From these, 15 qualified and were included in the systematic review. Among the selected studies, eight were RCTs, six were cross-sectional studies, and the remaining one was an in vitro experimental study. CONCLUSIONS: The toothbrush becomes contaminated even after its first usage, and the contamination level rises with continued use. There are a number of factors that lead to the contamination of brushes, such as increased humidity brought on by a plastic cover or a toilet setting. Charcoal brushes show significant efficacy as compared to regular bristles in reducing toothbrush contamination; however, more RCTs are needed to further assess its efficacy. Nevertheless, rinsing with chlorhexidine mouthwash after daily brushing shows favourable results.

AIM: The aim was to assess two macronutrient interventions in a 2 × 2 factorial dietary design to determine their effects on oral health. MATERIALS AND METHODS: Participants (65-75 years old) with a body mass index between 20 and 35 kg/m2 of a larger randomized control trial who consented to an oral health assessment were recruited. They had ad libitum access to one of four experimental diets (omnivorous higher fat or higher carbohydrate, semi-vegetarian higher fat or higher carbohydrate) for 4 weeks. The periodontal examination included periodontal probing depth (PPD), clinical attachment level (CAL), and bleeding on probing. Oral plaque and gingival crevicular fluid (GCF) were collected before and after the intervention. RESULTS: Between baseline and follow up, the number of sites with a CAL <5 mm (mean difference [MD] -5.11 ± 9.68, p = .039) increased and the GCF amount (MD -23.42 ± 39.42 Periotron Units [PU], p = .050) decreased for the semi-vegetarian high-fat diet. For the mean proportion of sites with PPD reduction of >1 mm and CAL gain of >1 mm, significant differences were calculated between the diets investigated. The clinical parameters were not associated with changes in the oral microbiota. CONCLUSIONS: The results of this study provided evidence that a semi-vegetarian high-fat diet provides benefits to clinical parameters of periodontal health. This study is registered in ClinicalTrials.gov (ACTRN12616001606471).

BACKGROUND: Partnering with patients and families to make decisions about care needs is a safety and quality standard in Australian health services that is often not assessed systematically. OBJECTIVE: The objective of this study was to retrospectively evaluate satisfaction with care and involvement in decision-making among family members of patients admitted to the intensive care unit (ICU). METHODS: A retrospective cohort analysis of a satisfaction survey administered to family members of patients admitted to an ICU in an Australian metropolitan tertiary care hospital from 2014 to 2019 was conducted. The Family Satisfaction in the Intensive Care Unit questionnaire (FSICU) questionnaire was used to assess overall satisfaction, satisfaction with care, and satisfaction with decision-making on a scale from "poor" (0) to "excellent" (100). RESULTS: In total, 1322 family members fully completed the survey. Respondents were typically direct relatives of ICU patients (94.2%) with an average age of 52.6 years. Most patients had an ICU length of stay <7 d (56.8%), with most patients being discharged to the ward (96.8%). The overall mean satisfaction score was high among respondents (90.26%). Similarly, mean satisfaction with care (93.06%) and decision-making (89.71%) scores were high. Satisfaction with decision-making scores remained lower than satisfaction with care scores. Multivariable modeling indicated that those younger than 50 years reported higher satisfaction scores (p = 0.006) and those with prolonged lengths of stay in the ICU were associated with lower overall satisfaction scores (p = 0.039). Despite some criticism of waiting times and noise levels, responses showed sincere gratitude for patients' treatment in the ICU and appreciation for the care, skill, and professionalism of the staff. CONCLUSION: Very high satisfaction levels were reported by family members during this study. Routine, prospective evaluations of family member satisfaction with ICU experiences are feasible and can be leveraged to provide insight for clinicians and administrators seeking to improve family satisfaction with decision-making and care in ICU settings and meet national standards.

Coronavirus disease 2019 (COVID-19), a mystified cryptic virus has challenged the mankind that has brought life to a standstill. Catastrophic loss of life, perplexed healthcare system and the downfall of global economy are some of the outcomes of this pandemic. Humans are raging a war with an unknown enemy. Infections, irrespective of age and gender, and more so in comorbidities are escalating at an alarming rate. Cardiovascular diseases, are the leading cause of death globally with an estimate of 31% of deaths worldwide out of which nearly 85% are due to heart attacks and stroke. Theoretically and practically, researchers have observed that persons with pre-existing cardiovascular conditions are comparatively more vulnerable to the COVID-19 infection. Moreover, they have studied the data between less severe and more severe cases, survivors and non survivors, intensive care unit (ICU) patients and non ICU patients, to analyse the relationship and the influence of COVID-19 on cardiovascular health of an individual, further the risk of susceptibility to submit to the virus. This review aims to provide a comprehensive particular on the possible effects, either direct or indirect, of COVID-19 on the cardiovascular heath of an individual.

BACKGROUND: aspiration pneumonia increases hospitalisation and mortality of older people in residential aged care. OBJECTIVES: determine potentially pathogenic microorganisms in oral specimens of older people with aspiration pneumonia and the effect of professional oral care in reducing aspiration pneumonia risk. DATA SOURCES: PUBMED/MEDLINE, CINAHL, EMBASE, COCHRANE, PROQUEST, Google Scholar, Web of Science. STUDY ELIGIBILITY CRITERIA: published between January 2001 and December 2019 addressing oral microorganisms, aspiration pneumonia, oral health and treatment. PARTICIPANTS: people 60 years and older in residential aged care. STUDY APPRAISAL AND SYNTHESIS METHODS: the Newcastle-Ottawa Scale and the Standard Protocol Items: Recommendations for Intervention Trials checklist. RESULTS: twelve studies (four cross-sectional, five cohort and three intervention) reported colonisation of the oral cavity of older people by microorganisms commonly associated with respiratory infections. Aspiration pneumonia occurred less in people who received professional oral care compared with no such care. Isolation of Candida albicans, Staphylococcus aureus, methicillin-resistant S. aureus and Pseudomonas aeruginosa was related to mortality due to aspiration pneumonia. An interesting finding was isolation of Escherichia coli, a gut bacterium. LIMITATIONS: more information may be present in publications about other co-morbidities that did not meet inclusion criteria. A high degree of heterogeneity prevented a meta-analysis. Issues included sampling size, no power and effect size calculations; different oral health assessments; how oral specimens were analysed and how aspiration pneumonia was diagnosed. CONCLUSIONS AND IMPLICATIONS OF KEY FINDINGS: pathogenic microorganisms colonising the oral microbiome are associated with aspiration pneumonia in older people in residential care; professional oral hygiene care is useful in reducing aspiration pneumonia risk.

AIM: Modern lifespan oral health research focuses on understanding the impact of periodontitis (or therapy) on clinical and patient-based outcome measures to provide effective care, improve patient safety according to the quality standards. For better targeted intervention and effective disease management, this systematically review aimed to investigate the relationship between non-surgical periodontal therapy and patient-based outcomes using OHIP-14. METHODS: Seven Databases were searched for studies on patient-based outcomes responses to periodontal treatment. The time-period defined from search was from January 1977 to January 2019. Two independent reviewers carried out data search, selection of studies, data extraction and quality assessment using Mixed Method Appraisal Tool. Prospective cohort studies, intervention studies and observational studies written in English demonstrating non-surgical periodontal therapy response on the patient-reported outcomes (using Oral Health Impact Profile 14) were included in the review. RESULTS: Thirteen studies were included in the review, which comprised of three randomised control trials, nine case series, and one was a quasi-experimental study. Eleven out of the 13 studies reported significant improvement in OHIP-14 scores amongst participants who had undergone non-surgical periodontal therapy. Physical disability, psychological discomfort and functional limitation were domains that improved significantly after non-surgical periodontal therapy in these studies. Physical pain was a common finding in short-term follow-up but improved significantly in long-term follow-up studies. CONCLUSION: Based on clinical and patient-based outcomes measurement, it is recommended that non-surgical periodontal therapy is a "gold standard" approach towards improving patient-based outcomes, reducing co-morbidities and enhancing patient safely immediately and in long term.

OBJECTIVE: To describe the characteristics of hospital admissions for dental conditions, by Australian Statistical Geography Standard remoteness area for the 5 years 2010/2011 to 2014/2015. DESIGN: Retrospective analysis of preventable hospital admissions due to dental conditions. SETTING: National data set provided by the Australian Institute of Health and Welfare. PARTICIPANTS: Every hospital admission for patients who were admitted for dental conditions over five financial years, from 2010/2011 to 2014/2015. MAIN OUTCOME MEASURES: The number (and rate per 1000 population) of hospital admissions due to dental conditions in each Australian Statistical Geography Standard remoteness area (major city, inner regional, outer regional, remote and very remote). RESULTS: There were 316 937 hospital admissions for dental conditions over the 5-year period. The rate of potentially preventable dental hospital admissions ranged from an average of 2.5 per 1000 population in major cities to 3.2 in inner regional areas, 3.1 in outer regional areas, and 4.1 per 1000 in remote and very remote areas. The rate of admissions was highest among those aged 0-14 years living in remote (9.0-10.0 per 1000) and very remote (9.8-12.5 per 1000) areas. Dental caries was the most common reason for admissions. CONCLUSIONS: There is an urgent need to address the social determinants of oral health in children aged 0-14 years living in remote and very remote Australia. The delivery of mobile primary dental care services needs to be expanded in remote and very remote areas to prevent and treat dental caries.

BACKGROUND: Over the past two decades, there has been a decrease in dental diseases in Australia; however, the number of preventable dental hospital admissions has not diminished. This review reports on the factors associated with preventable dental hospital admissions in Australia. METHODS: A search of five databases was conducted using Medical subject headings/Emtree terms and Index terms. All original studies, published between January1965 and March 2018 in English, based on the Australian population, and examining the prevalence of oral conditions as a cause for emergency department presentations and hospital admissions were included. The mixed method appraisal tool was used to evaluate the included studies. RESULTS: Eleven cross-sectional studies met inclusion and exclusion criteria. All the studies, except one from Tasmania, were from Western Australia. The most common reasons for preventable dental hospital admissions were dental caries, followed by embedded or impacted teeth. Malignant neoplasms were reported as main causes of preventable dental hospital admissions in the older population. CONCLUSIONS: Most studies on preventable dental hospital admissions were from one Australian state (Western Australia). Further research is required to determine the national prevalence and incidence of preventable dental hospital admissions. A periodic audit of preventable dental hospital admission data is needed for delivery of a fair and effective dental services.

BACKGROUND: Chronic periodontitis (CP) is a global public health issue. Studies have suggested CP could be linked to obesity due to their similar pathophysiological pathway. The aim of this study is to determine the prevalence of CP and to assess the predictors for CP among the obese Malaysian population. METHODS: This is a cross-sectional study on obese participants. Obesity is defined as an individual who has Body Mass Index (BMI) ≥ 27.5 kg/m(2). A convenience sampling method was used. A total of 165 paricipants were recruited. This study involved answering questionnaires, obtaining biometric and clinical measurements of Visible plaque index (VPI), Gingival bleeding index (GBI), Probing pocket depth (PPD) and Clinical attachment loss (CAL). Data analysis was carried out using SPSS statistical software (SPSS Inc., version 20, US). RESULTS: A total of 165 participants; 67 (40.6%) males and 98 (59.4%) females participated in the study. Mean age of the participants was 43.9 (± 8.9). The prevalence of CP among the obese population was found to be 73.9%. Out of this, 43 and 55% were categorised as moderate and severe CP respectively. Around 64% of participants had sites with CAL ≥ 4 mm and participants with sites with PPD ≥ 4 mm were reported to be 25%. Around 83% of the participants had sites with GBI ≥ 30 and 92% of participants had sites with VPI ≥ 20%. GBI and VPI were found to have significantly higher odds for CP. CONCLUSION: Prevalence of CP was high among obese Malaysians. GBI and VPI were potential predictors for CP in this obese population.

Introduction Bacterial meningitis (BM) is a neurologic emergency mainly affecting children under the age of two. Clinical symptoms are rarely evident in children, thus making a diagnosis is a challenge. Antibiotic therapy should be started timely to ensure the avoidance of significant morbidity and mortality. This study aims to assess the outcomes, mortality, and symptomatology of children presenting with BM in allied hospitals of Rawalpindi Medical University, Pakistan. Methods It is a cross-sectional study employing a sample size of 201, conducted at the Allied Hospitals of Rawalpindi Medical University, Pakistan from a period of January 2023 to August 2023. Non-probability convenience sampling was used. Children aged between newborns and 14 years of age with a confirmed diagnosis of bacterial meningitis were included in this study. The study population was divided into five different age groups. Three different outcomes were studied including complete recovery, development of complications, and death. Data was entered into and analyzed by Statistical Package for the Social Sciences (SPSS) version 25 (IBM Corp., Armonk, NY, USA). Descriptive statistics were applied to the demographic data. The chi-square analytical test was applied to study the association between the categorical variables. Results One hundred nineteen (59.2%) of the study's population were males. One hundred twenty-six (62.7%) of the patients were born through a spontaneous vaginal delivery (SVD). The majority (54%) of the study population were infants. Twenty-three percent were newborns, 13% were toddlers, 6% were preschool children, and 4% were school-age children. The majority (85%) of the study participants belonged to lower socioeconomic backgrounds. Ninety percent of the cases had symptoms of fever, seizures, and poor feeding. Neck stiffness was significantly associated with death as an outcome (p-value=0.01). The overall mortality amongst the study population was 20%. Forty-nine percent of the study population recovered completely, whereas 31% had complications following the diagnosis. Neonates had a higher mortality rate than infants (45% vs 9% respectively). Conclusion The most common presenting symptoms were fever, vomiting, seizures, and neck stiffness. Poor feeding was also seen in most cases. The rate of complications and death is observed to be relatively higher following the diagnosis of bacterial meningitis as compared to rates in the surrounding and developed countries. Out of all signs and symptoms, the presence of neck stiffness was significantly associated with death as an outcome among children with bacterial meningitis.
RESUMEN
Introduction Discharge summaries (DS) allow continued patient care after being discharged from the hospital. Only a few quality improvement projects (QIPs) focused on assessing and improving the quality and completeness of DS at tertiary care hospitals have been undertaken in Pakistan. This QIP aimed to evaluate and enhance the quality and completeness of DS at a tertiary care hospital in Pakistan to facilitate seamless healthcare transitions. Methods A QIP was conducted in the medical unit of a tertiary care hospital in Rawalpindi, Pakistan. The DS were assessed using the e-discharge summary self-assessment checklist devised by the Royal College of Physicians (RCP). This QIP was done by the plan, do, study, act (PDSA) cycle. The PDSA cycle comprised two audit cycles and an intervention in between them. The first audit cycle (AC) was conducted on 150 DS. Its duration was from March 2023 to June 2023. An educational workshop was conducted before the re-audit cycle (RAC) to address deficiencies and reinforce the implementation of the guidelines provided by the RCP. The RAC was conducted from June 2023 to August 2023. 100 DS were studied and analyzed to assess for improvement in the completeness of DS. Frequencies and percentages were calculated in each audit cycle. The Chi-squared test was applied to compare the statistical difference between the results of both audit cycles. Results A total of 150 DS were analyzed in the first AC and 100 DS in the RAC. The results of the first AC show that the details of any allergies were recorded only in 3% of the DS; this percentage significantly improved to 51% after the RAC (p-value <0.05). Relevant past medical history was included in 52% and 88% of the DS during the first AC and RAC, respectively (p-value <0.05). Secondary diagnoses were written in 54% and 71% of the DS during the first AC and RAC, respectively (p-value <0.05). Details of relevant investigations were included in 60% and 88% of the DS during the first AC and RAC, respectively (p-value <0.05). The post-discharge management plan was written in 90% and 98% of the DS during the first AC and RAC, respectively (p-value <0.05). The follow-up plan was written clearly in 65% and 93% of the DS during the first AC and RAC, respectively (p-value <0.05). Conclusion The DS was found to be incomplete after analyzing the results of the first AC. The details related to allergies, medications, operations, and procedures were found to be missing in the majority of the cases. No mention of the patient's concerns or expectations was made in the DS. The results of the RAC showed improvement in the level of completeness of DS. The majority of the weak points observed after the first AC seemed to have improved after the RAC, which shows that intervention proved to be quite effective in improving the completeness and quality of DS. The RAC showed significant improvement in the completeness of the details relating to investigations, allergies, past medical history, secondary diagnoses, and the post-discharge follow-up plan. QIP must be routinely carried out to assess and improve the completeness and quality of DS at hospitals.
RESUMEN
Purpose: The purpose of this systematic review is to assess the impact of shoulder surgeon volume of common shoulder procedures on hospital/surgeon efficiency, adverse events, and hospital costs. Methods: Four online databases (PubMed, Embase, MEDLINE, and CENTRAL) were searched for literature on the influence of surgeon volume on outcomes for shoulder surgery, from data inception to October 1, 2020. The Methodological Index for Non-Randomized Studies tool was used to assess study quality. Data are presented descriptively. Results: Twelve studies encompassing 150,898 patients were included in this review. The distribution of surgery type was rotator cuff repair (53.7%; n = 81,066), shoulder arthroplasty (35.7%; n = 53,833), and ORIF (10.6%; n = 15,999). Higher surgeon volume for rotator cuff repairs was associated with lower surgical time, length of stay, costs, and reoperation/readmission rates. For shoulder arthroplasty, higher surgeon volume was associated with lower length of stay, costs, surgical time, non-routine disposition, blood loss, reoperation/readmission, and complications. As for ORIF, higher surgeon volume was associated with lower length of stay, costs, and complications. Conclusion: A high surgical volume leads to improved results for hospital/surgeon efficiency and reduces adverse events and hospital costs across various orthopaedic procedures. Hospitals and physicians can use this information to develop and adhere to policies and practices that contribute to more efficient and better-quality care for patients. Level of Evidence: III.
RESUMEN
Background: Currently, is there no consensus on a widely accepted measurement technique for calculating the Hill-Sachs lesion (HSL). The purpose of this review is to provide an overview of the techniques and imaging modalities to assess the HSL pre-operatively. Methods: Four online databases (PubMed, Embase, MEDLINE, and COCHRANE) were searched for literature on the various modalities and measurement techniques used for quantifying HSLs, from data inception to 20 November 2021. The Methodological Index for Non-Randomized Studies tool was used to assess study quality. Results: Forty-five studies encompassing 3413 patients were included in this review. MRA and MRI showed the highest sensitivity, specificity, and accuracy values. Intrarater and interrater agreement was shown to be the highest amongst MRA. The most common reference tests for measuring the HSL were arthroscopy, radiography, arthro-CT, and surgical techniques. Conclusion: MRA and MRI are reliable imaging modalities with good test diagnostic properties for assessment of HSLs. There is a wide variety of measurement techniques and imaging modalities for HSL assessment, however a lack of comparative studies exists. Thus, it is not possible to comment on the superiority of one technique over another. Future studies comparing imaging modalities and measurement techniques are needed that incorporate a cost-benefit analysis.
RESUMEN
We have developed a general process for the formation of α-arylethers via the Pd-catalyzed arylation of secondary α-alkoxytricyclohexylstannanes. Incorporation of cyclohexyl spectator ligands into the alkylstannane and the use of the electron-deficient ligand JackiePhos (1) are critical for achieving selective alkyl transfer in this process. This system circumvents the need for a coordinating/directing oxygen-protecting group to promote selective alkyl transfer and enables α-tetrahydropyran, α-tetrahydrofuran, and open-chain secondary α-alkoxy groups to be employed efficiently in Pd-catalyzed Stille reactions with a broad range of aryl electrophiles. These findings suggest that selective transmetalation of a single marginally activated secondary alkyl unit from Sn to Pd should be broadly achievable provided that unactivated secondary alkyl ligands comprise the other three groups of the tetraalkylstannane.

While surgical resection has remained the mainstay of treatment in early-stage renal cell carcinoma (RCC), therapeutic options in the advanced setting have remarkably expanded over the last 20 years. Tyrosine kinase inhibitors targeting the vascular endothelial growth factor receptor (VEGF-TKIs) and anti-programmed cell death 1 (PD-1)/anti-programmed death-ligand 1 (PD-L1)-based immune checkpoint inhibitors (ICIs) have become globally accepted options in the upfront metastatic setting, with different ICI-based combination strategies improving overall survival compared to single-agent Sunitinib. Although some patients benefit from long-term responses, most eventually develop disease progression. Ongoing efforts to better understand the biology of RCC and the different mechanisms of acquired resistance have led to the identification of promising therapeutic targets. Belzutifan, a novel agent targeting the angiogenic pathway involving hypoxia-inducible factors (HIFs), has already been approved for the treatment of early-stage tumors associated with VHL disease and represents a very promising therapy in advanced RCC. Other putative targets include epigenetic regulation enzymes, as well as several metabolites such as adenosine, glutaminase and tryptophan, which are critical players in cancer cell metabolism and in the tumor microenvironment. Different methods of immune regulation are also being investigated, including CAR-T cell therapy and modulation of the gut microbiome, in addition to novel agents targeting the interleukin-2 (IL-2) pathway. This review aims to highlight the emergent novel therapies for RCC and their respective completed and ongoing clinical trials.

This systematic review and meta-analysis aimed to generate pooled evidence for the association between excessive weight and pregnancy induced periodontitis. EMBASE, SCOPUS, PubMed/MEDLINE, Web of Science, BVS/LILACS, Cochrane Library and SCIELO databases were accessed. Eligibility criteria were: human clinical studies published between year 2000 and 2021. Newcastle-Ottawa scale was used to evaluate risk of bias of the studies. Meta-analysis was performed using MedCalc® Statistical Software. Eleven studies were included, evaluating 2152 pregnant women (743 with overweight/obesity and 1409 with normal body mass index - BMI), with a mean age of 29.62 years. Most studies had low risk of bias. A positive association between overweight/obesity and periodontitis was found, with an average of 61.04% of women with overweight/obesity and periodontitis, showing the overall random-effects relative risk and 95% CI of 2.21 (1.53-3.17) (p < 0.001). Arterial hypertension, gestational diabetes mellitus and excessive gestational weight gain were the most common adverse effects of maternal obesity that may have been linked to periodontitis induced pro-inflammatory state. In conclusion, a positive association was found between overweight/obesity and periodontitis during pregnancy. However, the high heterogeneity between the studies related to sample size, periodontal classification and the cutoff-points for BMI are the main limitation.
RESUMEN
The epithelial cell adhesion molecule (EpCAM) is considered an essential proliferation signature in cancer. In the current research study, qPCR induced expression of EpCAM was noted in acute lymphoblastic leukemia (ALL) cases. Costunolide, a sesquiterpene lactone found in crepe ginger and lettuce, is a medicinal herb with anticancer properties. Expression of EpCAM and its downstream target genes (Myc and TERT) wasdownregulated upon treatment with costunolide in Jurkat cells. A significant change in the telomere length of Jurkat cells was not noted at 72 h of costunolide treatment. An in silico study revealed hydrophobic interactions between EpCAM extracellular domain and Myc bHLH with costunolide. Reduced expression of NFκB, a transcription factor of EpCAM, Myc, and TERT in costunolide-treated Jurkat cells, suggested that costunolide inhibits gene expression by targeting NFκB and its downstream targets. Overall, the study proposes that costunolide could be a promising therapeutic biomolecule for leukemia.
RESUMEN
Introduction: Freeman-Sheldon syndrome (FSS), also known as the distal arthrogryposis (DA) type 2A, is a rare congenital anomaly. We report a unique case of the DA type 2A with mixed clinical features and the unusual presentation of bilateral congenital dislocation of the knee but had unassisted stiff knee gait. Case Report: A 5-year-old female child presented to the clinic with the complaint of inability to bend both knees since birth. She had an unassisted bipedal gait, but could not squat, cross-leg sit, run, and climb stairs without assistance. Her youngest brother had a similar presentation but succumbed to death at the age of 5 months due to respiratory distress. Clinical features were in the favor of FSS. Her serum creatinine kinase level was normal and the electromyography of bilateral tibialis anterior and abductor pollicis brevis was not suggestive of the myotonia. Radiograph of the skull showed cooper beaten skull appearance whereas bilateral pelvis with the hip showed following changes in the right hip; decrease femoral epiphysis height, horizontal proximal femoral physis, and the coxa brevia. She was initially managed conservatively by weekly stretching, manipulation, and casting. As a result, she could flex her knee up to 20°. Although the quadricepsplasty might be helpful for the persistent extension deformity, there was marked quadriceps weakness which could make it harder for the child to stand and walk. In addition, the abnormal muscle physiology in FSS may result in unfavorable outcomes after the surgery. Moreover, a consideration of the surgical aspect is not free of risks which include difficult endotracheal intubation, vein access, and malignant hyperthermia. Conclusion: FSS is a rare congenital anomaly that should be differentiated from another syndrome of the close resemblance, Sheldon Hall syndrome and Schwartz Jampel syndrome which are other rare autosomal recessive disorders characterized by myotonia and the chondrodysplasia. Conservative management has still a role in bilateral knee involvement especially if the patient is an independent walker.
RESUMEN
BACKGROUND: NCIT are non-invasive devices for fever screening in children. However, evidence of their accuracy for fever screening in adults is lacking. This study aimed to compare the accuracy of non-contact infrared thermometers (NCIT) with temporal artery thermometers (TAT) in an adult hospital. METHODS: A prospective observational study was conducted on a convenience sample of non-infectious inpatients in 2 Australian hospitals. NCIT and TAT devices were used to collect body temperature recordings. Participant characteristics included age, gender, skin color, highest temperature, and antipyretic medications recorded in last 24-hour. RESULTS: In 265 patients, a mean difference of ± 0.26°C was recorded between the NCIT (36.64°C) and the reference TAT (36.90°C) temperature devices. Bland-Altman analysis showed that NCIT and TAT temperatures were closely aligned at temperatures <37.5°C, but not at temperatures >37.5°C. NCIT had low sensitivity (16.13%) at temperatures ≥37.5°C. An AUROC score of 0.67 (SD 0.05) demonstrated poor accuracy of the NCIT device at temperatures ≥37.5°C. CONCLUSION: This is the first study to compare accuracy of NCIT thermometers to TAT in adult patients. Although mass fever screening is currently underway using NCIT, these results indicate that the NCIT may not be the most accurate device for fever mass screening during a pandemic.
