Acute osteomyelitis, thrombophlebitis, and pulmonary embolism: a case report.

BACKGROUND: Septic pulmonary embolism (SPE), deep vein thrombophlebitis (DVT), and acute osteomyelitis (AOM) form a triad that is rarely seen in children and is usually associated with a history of trauma on long bones. Unfortunately, a delay in diagnosis is frequently observed in this syndrome, which places the patient at risk of life-threatening complications. This delay can largely be attributed to the failure to consider osteomyelitis as a potential underlying cause of DVT. CASE PRESENTATION: In this case report, we present the case of a 16-year-old Arabian male who presented with limb trauma and fever. The patient had a delayed diagnosis of osteomyelitis, which resulted in the formation of an abscess and subsequent joint destruction. Surgical drainage and joint replacement surgery were deemed necessary for treatment. CONCLUSIONS: persistent fever along with a history of trauma on a long bone with signs of DVT of the limb in a child should raise concern for osteomyelitis and an MRI evaluation of the limb should be obtained.

Malaria and an Amoebic Abscess in a Returning Traveler from Liberia.

Malaria is an infectious Anopheles mosquito-borne disease caused by five different eukaryotic protozoa parasites. Amoebiasis is a parasitic infection caused by Entamoeba histolytica. Both diseases are widespread in Liberia. A returning traveler was diagnosed and treated for malaria, and 20 days later, an amoebic liver abscess was discovered, meaning that the malaria infection masked the amoebic infection, which emphasizes the importance of a complete examination of returning travelers, especially for those returning from Sub-Saharan Africa, where coinfections are more common. Herein, we propose that the relationship between Malaria and amoebic liver abscesses should be explored by researching the effects of malaria on ferritin levels and the immune components in the liver and whether it helps the emergence of hepatic amoebic abscesses or not.

Syrian national growth references for children and adolescents aged 2-20 years.

BACKGROUND: During the past three decades, growth charts have become one of the principal tools for monitoring anthropometric development in individuals and populations as well. Growth references by the CDC and other countries have been widely used in our hospitals and healthcare units for clinical assessment of children's development. The apparent overestimation and underestimation of many children's anthropometrics indicated the need to construct our own references. The objective of this study is to establish the national growth references for the Syrian population 2-20-year-old. METHODS: A multicenter cross-sectional sample of 13,548 subjects, aged 2-20 years, were recruited from various kindergartens, schools, and universities across the Syrian Arab Republic between February and May-2019. Response variables (stature, weight, and BMI) were fitted against age using P-splines and three empirical distributions: Box-Cox T, Box-Cox Power Exponential, and Box-Cox Cole and Green. Residuals diagnostic Q-tests and worm plots were used to check the validity of fitted models. RESULTS: Box-Cox T provided the best fit for stature-for-age, whereas Box-Cox Power Exponential provided the best fit for weight-for-age and BMI-for-age. Residuals diagnostics revealed adequate models fitting. BMI cutoffs revealed an increased prevalence of obesity (4.5% and 3.66%) and overweight (20.1% and 19.54%), for boys and girls respectively, in our population. CONCLUSIONS: Growth charts are available for use now in our hospitals and healthcare units. For 0-2-year-old children, we recommend using the World Health Organization's standards.

Primary psoas tuberculosis abscess with an iliac bone lytic lesion: a case report.

BACKGROUND: Primary psoas tuberculosis is the presence of "Koch's bacillus'' within the iliopsoas muscle caused by hematogenous or lymphatic seeding from a distant site. Muscular tuberculosis has relatively low prevalence in comparison with other cases of extrapulmonary tuberculosis, which explains the difficulties in establishing the diagnosis. CASE PRESENTATION: In this report, we present a challenging diagnostic case of primary psoas tuberculosis in a 38-year-old middle eastern female from southern Syria. The diagnosis was based on the clinical orientation, the observation of pulmonary lesions on the computed tomography scan, and the necrotic signs in the vicinity of the infected area. Despite the misleading primary false-negative results, the final diagnosis was reached after sufficient repetition of tuberculosis-specific testing. The patient was treated with isoniazid-rifampin-pyrazinamide-ethambutol for 2 months, then isoniazid and rifampin for 7 months, with full recovery in follow-up. CONCLUSIONS: This case highlights the importance of a clinical-based approach in the treatment of patients with psoas abscesses, especially in areas with high tuberculosis prevalence.

Protective Measures Practices Among Hospitals' Professionals Working in a Fragile Health System.

OBJECTIVE: This study aimed to assess the protective measures among health-care workers (HCWs) in a war-torn area during coronavirus disease 2019 (COVID-19) pandemic. METHODS: An online cross-sectional questionnaire was administrated to HCWs in Syria between April 1 and May 21, 2020. The questions aimed to assess the HCWs' application of safety, hygiene, and necessary protection considerations while attending to suspected or proven COVID-19 cases. Unpaired t-test and 1-way analysis of variance (ANOVA) were used for statistical analysis. RESULTS: Of the 290 participants included in the statistical analysis, 250 were medical doctors. Low scores of protective practices were noticed among the participants, as only 12% of doctors had a score above 6/15 points, and only 37.5% of nurses had a score of more than 4/12 points. Medical doctors who were not on the frontlines scored significantly higher than those who were on the frontlines (4.69 vs 3.80 points, respectively; P < 0.001). CONCLUSIONS: More courses and training sessions should be implemented to improve the practice of protective measures among HCWs (frontliners in particular) in areas with fragile health systems, such as Syria, during the COVID-19 pandemic, especially those on the frontlines. Moreover, specific COVID-19 protection measures guidelines to low-income countries are needed.

Endocarditis-induced thrombotic thrombocytopenic purpura mimicking preeclampsia: A case report.

TTP, Preeclampsia have similar manifestations in pregnancy. Establishing the right diagnosis is essential as the treatment is different. Endocarditis-induced TTP should be suspected when neurological symptoms, thrombocytopenia are present.

The Impact of Modifying Empirical Antibiotic Therapy Based on Intestinal Colonization Status on Clinical Outcomes of Febrile Neutropenic Patients.

BACKGROUND: This paper aimed to inspect factors affecting febrile neutropenia patients with hematologic malignancies. The intestinal colonization rate of extended-spectrum beta-lactamase-producing Enterobacteriaceae (ESBL-E) and carbapenem-resistant Enterobacteriaceae (CRE) was assessed. The rate of subsequent ESBL-E and CRE bacteremia correlated with corresponding bacterial colonization was evaluated. Further, the risk factors for ESBL-E and CRE intestinal colonization were examined. Finally, the impact of rectal swab screening combined with adapted empirical antibiotic therapy on the mortality rate of patients with febrile neutropenia was assessed. MATERIALS AND METHODS: Febrile neutropenia patients underwent rectal swabs and collection of blood culture specimens upon admission. Empirical treatment was subsequently modified according to rectal swab results if necessary. Bacteremia patients were treated according to blood culture results. Explorative forward-stepwise logistic regression analyses were used to identify risk factors for ESBL-E and CRE fecal carriage and mortality. RESULTS: In total, 201 rectal swabs and 402 blood samples were collected from 163 patients during 201 febrile neutropenia episodes. Of these episodes, 38 (18.90%) were colonized with ESBL-E and 30 (14.92%) with CRE. Bloodstream infections developed in 29/201 (14.42%) episodes. Only bacteremia episodes caused by Gram-negative bacilli were included in our analysis. The development of Gram-negative-rod bacteremia was observed in eight out of 38 (21.05%) ESBL-E colonized episodes and four out of 30 (13.33%) CRE-colonized episodes. A BSI developed in three out of 38 (7.89%) ESBL-E colonized episodes, and two out of 30 (6.66%) CRE-colonized episodes developed BSI with the respective organism. Multivariate analysis identified previous quinolone use as the only independent risk factor for fecal colonization of multi-drug-resistant (MDR) Enterobacteriaceae (ESBL-E and CRE) (odds ratio, 17.09; 95% confidence interval, 5.29 - 55.18; P <0.0001). No significant association was observed between ESBL-E and CRE carriage and increased risk of developing subsequent bacteremia. No significant differences were detected between groups receiving modified and non-modified treatments in duration of hospitalization or antibiotic therapy (univariate analysis) and 28-day mortality rate (logistic regression). CONCLUSION: Quinolone exposure was a major risk factor for ESBL-E and CRE fecal carriage. Performing rectal swab screening for MDR Enterobacteriaceae and modifying empirical antibiotic therapy accordingly did not improve clinical outcomes of febrile neutropenia patients.

COVID-19 paraclinical diagnostic tools: Updates and future trends.

MOTIVATION: COVID-19 is one of the most widely affecting pandemics. As for many respiratory viruses-caused diseases, diagnosis of COVID-19 relies on two main compartments: clinical and paraclinical diagnostic criteria. Rapid and accurate diagnosis is vital in such a pandemic. On one side, rapidity may enhance management effectiveness, while on the other, coupling efficiency and less costly procedures may permit more effective community-scale management. METHODOLOGY AND MAIN STRUCTURE: In this review, we shed light on the most used and the most validated diagnostic tools. Furthermore, we intend to include few under-development techniques that may be potentially useful in this context. The practical intent of our work is to provide clinicians with a realistic summarized review of the essential elements in the applied paraclinical diagnosis of COVID-19.

A review of potential treatments to date in COVID-19 patients according to the stage of the disease.

INTRODUCTION AND MOTIVATION: Since the end of 2019, the COVID-19 pandemic has affected millions of people worldwide. With the rapid spread of this virus, an immense burden has fallen upon both healthcare and economic systems. As a consequence, there is an unprecedented urgency for researchers and scientific committees from all over the world to find an effective treatment and vaccine. REVIEW STRUCTURE: Many potential therapies are currently under investigation, with some, like Hydroxychloroquine, being authorized for emergency use in some countries. The crucial issue is now clearly to find the suitable treatment strategy for patients given comorbidities and the timeline of the illness. Vaccines are also under development and phase 1 clinical trials are rolling. Despite all efforts, no single drug or vaccine has yet been approved. In this review, we aim at presenting the proposed pathophysiological mechanisms of SARS-CoV-2 and to provide clinicians with a brief and solid overview of the current potential treatments classified according to their use at the three different currently proposed disease stages. In light of pathogenesis and proposed clinical classification, this review's purpose is to summarize and simplify the most important updates on the management and the potential treatment of this emergent disease.

Aspirin dosage for the prevention of graft occlusion in people undergoing coronary surgery: A systematic review and meta-analysis.

BACKGROUND: Aspirin is almost always used after coronary artery bypass graft (CABG) surgery; however, it is unclear what optimal dose should be prescribed. In this systematic review, we evaluated the effects of high versus low-dose aspirin in patients after CABG. METHODS: A comprehensive database search was conducted in several databases from date of inception until February 2018. There were no language restrictions. We included studies that compared different doses of aspirin in patients that had undergone CABG surgery. We included studies that evaluated patient-important outcomes (mortality, cardiovascular events, and gastrointestinal bleeding); and if not reported, we collected data on the surrogate outcome thromboxane B2 (TXB2). We collected relevant data and performed a meta-analysis. RESULTS: We identified 5903 references, and after two levels of screening by two independent reviewers, we included three randomized controlled trials in the meta-analysis with a total number of 122 participants. Mean age of trial participants was 65.63 years, and 88.68% were male. We planned to analyze all possible clinical outcomes, including mortality, recurrence, and hospitalization. However, no clinical outcomes are reported by the literature. The surrogate biochemical outcome of serum TXB2 was the only outcome reported by the eligible studies. High-dose aspirin (162-325mg once daily) achieved better suppression of TXB2 than low-dose aspirin (75-100mg once daily) (mean difference [MD], 2.00ng/mL, 95% confidence interval [CI]: 0.72-3.32; participants = 122; studies = 3; I2 = 0%). CONCLUSIONS: We found no clinical trials addressing any of the clinical outcomes of interest. High-dose aspirin was superior to low-dose aspirin in suppressing platelet function, a surrogate outcome. Trials evaluating clinical and patient-important outcomes are needed to better inform medical practice and fill this gap in clinical knowledge.

Castleman's disease with TAFRO syndrome: a case report from Syria.

Castleman's disease is a rare disorder, yet a rarer newly described syndrome called TAFRO syndrome was discovered to accompany it. TAFRO represents the constellation of symptoms (Thrombocytopenia, Anasarca, MyeloFibrosis, Renal failure, Organomegaly). Most cases were described in Japan. We present the first case of TAFRO syndrome in Syria. A 58-year-old Caucasian male with no relevant history presented with fatigue, oliguria, decreased platelets, increased creatinine level, hepatosplenomegaly, ascites, pitting edema and lymph node enlargement. Possible differential diagnoses were excluded by laboratory, radiologic and cytologic tests including TB, malignancy and autoimmune diseases. A biopsy of a supraclavicular lymph node confirmed Castleman disease. Our patient had Catleman's disease, and presented with only four diagnostic criteria for TAFRO syndrome (Myelofibrosis was absent) in addition to other minor characteristics (microcytic anemia, negative HIV and HHV-8 infections.) which make the presentation consistent with TAFRO syndrome described in the Japanese cases. The criteria for diagnosing TAFRO syndrome are still changing, and the pathophysiology behind it is unclear. We recommend further research to understand this syndrome taking into account that its prevalence might be worldwide.
