RESUMO

Introduction: Infective endocarditis is an infection of the endothelial surfaces of the heart. It is more prevalent in adults but its incidence in the pediatric population has been on the rise. The most important factor remains congenital heart disease and the most isolated pathogen is viridans group streptococcus. Methods: In this manuscript, we present a 20-year experience of a major referral tertiary care center in diagnosing and treating pediatric patients with endocarditis. A retrospective analysis of records of patients who were diagnosed with infective endocarditis under the age of 18 years is presented in this study. Variables relating to the demographic, imaging, microbiologic and pathologic data are described. Outcomes relating to complications and need for surgical repair are also portrayed. Results: A total of 70 pediatric patients were diagnosed with endocarditis in this time interval. The medical records of 65 patients were comprehensively reviewed, however the remaining 5 patients had severely missing data. Of the 65 patients, 55.4% were males, and the mean age at diagnosis was 7.12 years. More than half of the population (58.5%) had vegetation evident on echocardiography. The pulmonary valve was the most commonly affected (50%), followed by the mitral valve and tricuspid valves (15.6%). Most patients received empiric treatment with vancomycin and gentamicin. Viridans group streptococcus was the most frequently isolated organism (23.4%). Conclusion: Among pediatric patients diagnosed with endocarditis in this study, data pertaining to valve involvement and microbiologic information was consistent with the published literature. The incidence of complications and the need for surgical repair are not significantly correlated with demographic and clinical variables.

RESUMO

BACKGROUND: Chylothorax is the accumulation of chyle fluid in the pleural space. The incidence of chylothorax is quite common post-cardiac surgeries in pediatrics especially in Fontan procedures. Although several treatment lines are known for the management of chylothorax, steroids were scarcely reported as a treatment option. We present a unique case of a 4-year-old child who underwent Fontan procedure and suffered a long-term consequence of chylothorax. The chylothorax only fully resolved after introducing corticosteroids as part of her management. METHODS: A literature review about management of chylothorax post-cardiac surgery in children using Ovid Medline (19462021), PubMed, and google scholar was performed. CONCLUSION: Conservative management without additional surgical intervention is adequate in most patients. Additionally, somatostatin can be used with variable success rate. However, a few cases mentioned using steroids in such cases. More research and reporting on the use of steroids in the treatment of chylothorax post-cardiac surgeries in children is needed to prove its effectivity. In this article, we describe a case of chylothorax post-Fontan procedure that supports the use of steroids.

RESUMO

INTRODUCTION: QT interval represents the ventricular depolarization and repolarization. Its accurate measurement is critical since prolonged QT can lead to sudden cardiac death. QT is affected by heart rate and is corrected to QTc via several formulae. QTc is commonly calculated on the ECG and not the 24-h Holter. METHODS: 100 patients presenting to our institution were evaluated by an ECG followed by a 24-h Holter. QTc measurement on both platforms using Bazett and Fridericia formulae was recorded and compared. RESULTS: Mean age was 14.09 years, with the majority being males. Mean heart rate was 125.87. In the ECG, the mean QTc interval via the Bazett formula was 0.40 s compared with 0.38 s using the Fridericia formula. The mean corrected QT via the Bazett formula was 0.45, 0.39, and 0.42 s for the shortest RR, the longest RR, and the average RR, respectively. In contrast to the Fridericia formula, the corrected QT interval was 0.40, 0.39, and 0.40 s for the shortest RR, the longest RR, and the average RR, respectively. Using the Bazett formula, the highest specificity was reached during the longest RR interval (92.2%), while the highest sensitivity was recorded during the shortest RR interval (40%). As for the Fridericiaformula, sensitivity always reached 0%, while the highest specificity was reached during the average RR interval. CONCLUSION: QTc measured during Holter ECG reached a high specificity regardless of RR interval using the Fridericia and during the longest and the average RR interval for the Bazett formula. The consistently low sensitivity reveals that Holter ECG should not be used to rule out prolonged QT.

RESUMO

INTRODUCTION: Programmed death ligand-1 expression has been shown to be a good predictor of response to cancer therapy with checkpoint inhibitors. Its expression varies among different tumor types and among non-small cell lung cancer patients with different clinical and demographic characteristics. The prevalence and determinants of programmed death ligand-1 expression have been previously reported from various regions of the world, but data from Lebanon are lacking. This study examines the prevalence and the clinical, demographic and pathological predictors of programmed death ligand-1 expression in patients diagnosed with non-small cell lung cancer in Lebanon. METHODS: Medical records of 180 patients diagnosed with primary non-small cell lung cancer at our institution and tested for programmed death ligand-1 expression were reviewed. Clinical, demographic and pathological information were collected and correlated with programmed death ligand-1 expression using the chi-square test and logistic regression. RESULTS: One hundred eleven of the 180 non-small cell lung cancer tumor samples tested positive for programmed death ligand-1 expression (61.7%). 27.2% of those tumor samples expressed programmed death ligand-1 in 1%-49% of tumor cells, while 34.4% of tumor samples expressed programmed death ligand-1 in 50% or more of their cells. Squamous histology and advanced stage were significant predictors of programmed death ligand-1 expression (odds ratio = 2.79, 95% confidence interval [1.13-6.90], p = 0.012 and odds ratio = 2.48, 95% confidence interval [1.23-4.99], p = 0.044, respectively). CONCLUSION: Similar to reports from other populations, our results suggest that programmed death ligand-1 expression in non-small cell lung cancer is highly prevalent in the Lebanese population, especially in patients with advanced stage at diagnosis or squamous cell carcinoma histology. Because of the small sample size, while more that 60% of the patients are Lebanese, the results of this article cannot be extrapolated to the Middle Eastern and the Levantine population.

RESUMO

The global spread of COVID-19 has imparted significant economic, medical, and social burdens. Like adults, children are affected by this pandemic. However, milder clinical symptoms are often experienced by them. Only a minimal proportion of the affected patients may develop severe and complicated COVID-19. Supportive treatment is recommended in all patients. Antiviral and immunomodulatory medications are spared for hospitalized children with respiratory distress or severe to critical disease. Up till now, remdesivir is the only USFDA-approved anti-COVID-19 medication indicated in the majority of symptomatic patients with moderate to severe disease. Dexamethasone is solely recommended in patients with respiratory distress maintained on oxygen or ventilatory support. The use of these medications in pediatric patients is founded on evidence deriving from adult studies. No randomized controlled trials (RCTs) involving pediatric COVID-19 patients have assessed these medications' efficacy and safety, among others. Similarly, three novel monoclonal anti-SARS-CoV-2 spike protein antibodies, bamlanivimab, casirivimab and imdevimab, have been recently authorized by the USFDA. Nonetheless, their efficacy has not been demonstrated by multiple RCTs. In this review, we aim to dissect the various potential therapeutics used in children with COVID-19. We aspire to provide a comprehensive review of the available evidence and display the mechanisms of action and the pharmacokinetic properties of the studied therapeutics. Our review offers an efficient and practical guide for treating children with COVID-19.

RESUMO

BACKGROUND: SARS-CoV-2 is a new strain of the coronavirus family that emerged by the end of 2019 and led to the unpreceded COVID-19 pandemic. The virus affects multiple organs simultaneously and leads to a high rate of morbidity and mortality in all age groups. The cardiovascular system is one of the major affected organ systems. Various mechanisms including direct myocardial injury contribute to the cardiac manifestations of COVID-19 patients. METHODS: We performed a comprehensive and updated search on the cardiac manifestations of COVID-19. Our search included laboratory and imaging evaluations. In addition, we added a unique section on the effect of SARS-CoV-2 on the cardiovascular system in the pediatric population. RESULTS: COVID-19 might have an effect on the cardiovascular system at various levels leading to myocardial ischemia, arrhythmia, heart failure, myocarditis, and multisystem inflammatory syndrome in children. The incidence of cardiovascular complications varies among patients. This paper also provides a comprehensive summary of all the reported pediatric cases with cardiac manifestations. CONCLUSION: Multidisciplinary teams are crucial for adequate management of patients with COVID-19 regardless of age. Timely diagnosis is critical in reducing mortality.

RESUMO

Multiple randomized studies have shown that combination of chemotherapy and immune checkpoint inhibitors (ICIs) leads to better response rates and survival as compared to chemotherapy alone in the advanced stage of NSCLC. Data suggesting a benefit to using ICIs in the neoadjuvant therapy of patients with early stage NSCLC are emerging. Eligible subjects were treatment naïve patients with stage IB, II, and resectable IIIA NSCLC. Patients received three cycles of neoadjuvant chemotherapy with four doses of avelumab every 2 weeks. Patients with squamous cell cancer received cisplatin or carboplatin on day 1 and gemcitabine on days 1 and 8 of each cycle of chemotherapy. Patients with nonsquamous histology received cisplatin or carboplatin with pemetrexed on day 1 of each cycle. Patients then proceeded to their planned surgery. Out of 15 patients accrued as part of stage 1 of the study, four had a radiologic response (1 complete response), lower than the minimum of six responses needed to continue to phase 2 of the study. The study was therefore terminated. Majority had adenocarcinoma histology and stage IIIA disease. The treatment was well tolerated with no unexpected side effects. Four patients (26.7%) had grade III/IV CTCAE toxicity. This study confirms that the preoperative administration of chemotherapy and avelumab is safe. There was no indication of increased surgical complications. The benefit of adding immunotherapy to chemotherapy did not appear to enhance the overall response rate of patients in the neoadjuvant setting in patients with resectable NSCLC because this study failed to meet its primary endpoint.

RESUMO

Bacterial pericarditis is a critical diagnosis caused by a wide range of organisms including Streptococcus pneumoniae and other anaerobic organisms like Cutibacterium acnes which has been gaining more importance as a causative organism. Cutibacterium species are Gram-positive microaerophilic rods that constitute part of the normal flora of skin and mucosal membranes. The incidence of pericarditis caused by this organism is underreported as it is often dismissed as a skin flora contaminant. However, if left untreated, Cutibacterium acnes can cause pericarditis with serious complications. In this paper, we present a comprehensive review of the literature regarding pericarditis caused by Cutibacterium acnes along with a case presentation from our institution. In our institution, a 20-year-old man with history of atrial septal defect presented with chest pain radiating to the back along with symptoms of upper respiratory tract infection including headaches and myalgia. Electrocardiogram was remarkable for diffuse low-voltage waves. Echocardiography revealed a large pericardial effusion with tamponade features. Pericardiocentesis drained 1.2 L of milky fluid. Pericardial fluid analysis grew Cutibacterium acnes after being cultured for 8 days. The patient received 3 weeks of IV penicillin followed by 3 weeks of oral amoxicillin along with nonsteroidal anti-inflammatory agents and colchicine with no recurrence. Pericarditis caused by Cutibacterium acnes requires a high clinical suspicion since isolation of this organism can be dismissed as a skin flora contaminant. Literature review reveals that this infection may be underdiagnosed and underreported. Prompt diagnosis may lead to timely initiation of antibiotics which can help prevent devastating complications like constrictive pericarditis. Prospective studies are needed to evaluate the true incidence and prevalence of this disease.

RESUMO

INTRODUCTION: Port-a-Cath or chemoport provides prolonged central venous access for cancer patients requiring prolonged chemotherapy. Prolonged use of chemoport is associated with many complications. Dislodgement and migration of chemoport catheter is a rare and reportable complication with potentially serious consequences. METHODS: The medical charts of 1222 paediatric cancer patients admitted to the Children's Cancer Center in Lebanon who had chemoports inserted for long-term chemotherapy were retrospectively reviewed. Descriptive analysis of data was conducted. RESULTS: Chemoport fracture and migration were found in seven cases with an incidence of 0.57%. The duration of chemoport use before the event of dislodgement varied from 2 months to 102 months. Non-functioning chemoport was the most common presentation. Totally, six cases were managed successfully by loop snaring, three cases by paediatric cardiology team, and three cases by interventional radiology team. One case was managed surgically during chemoport removal. CONCLUSION: Fracture and migration of chemoport catheter is a rare complication of uncertain aetiology and with potentially serious consequences. Percutaneous retrieval, done by experienced cardiologist or interventional radiologist, is the first choice for management of this complication as it is considered as a safe and effective approach.

RESUMO

BACKGROUND: Congenital left atrial wall aneurysms are rare abnormalities that arise from a developmental weakness in the muscular wall. It may be misdiagnosed or go undetected and the delay in diagnosis can lead to catastrophic consequences. CASE PRESENTATION: An updated and comprehensive review of the literature was performed for all patients with this abnormality under the age of 18. A total of 15 cases including ours are presented in this article. We present a 10-month-old boy who was referred to our center for cardiomegaly. Workup revealed a large atrial wall aneurysm that was successfully corrected with surgery. CONCLUSION: Historically, left atrial aneurysms were uncommon in the absence of valvular heart disease or other cardiac conditions. Congenital aneurysms are rare phenomenon because they arise without an acquired cardiac disease and surgical correction is crucial for survival.

RESUMO

Lung cancer remains the leading cause of cancer death in both men and women worldwide. Tobacco smoking remains the single most important factor. Recent research has focused on the role of nutrition and dietary habits on lung tumorigenesis. With many individual reports on separate dietary aspects, no single review is available in the literature that summarizes the updated studies. To our knowledge, this is the first review that comprehensively reviews the updated literature on the effect of dietary habits on lung cancer. This review was concluded in February 2019 and included all meta-analyses, systematic reviews, and literature reviews. Thirty studies were retrieved in total. Items in the diet that offer a protective effect on lung parenchyma are fruits, vegetables, fish, nuts, soy, B vitamins, vitamin D, vitamin E, vitamin C, and zinc. Changing dietary habits to decrease the risk of lung cancer can be performed in parallel with smoking cessation programs. There is a need for future studies with large sample sizes to accurately evaluate some aspects of nutrition and their effect on lung cancer risk. Physicians are encouraged to provide nutritional advice to their patients.

RESUMO

There is a high prevalence of hypertension among Lebanese adults, but no evidence is available on its prevalence and control exclusively among older adults (65 + years). This study provides the first evidence on a representative sample of 502 community elderly and presents the basis for future research and policy implications. Results show an overall prevalence of 52% with a significantly higher female-to-male ratio. Factors independently associated with hypertension were older age, body mass index, and dementia. More than a third of those with a positive history of hypertension had uncontrolled blood levels. Uncontrolled hypertension was higher among women. Increasing awareness about medication adherence and controlling multi-morbidities constitute promising measures to lowering the burden of hypertension among Lebanese older adults, especially women.

RESUMO

BACKGROUND: Chylopericardium is the collection of lymph fluid inside the pericardial cavity. The incidence of chylopericardium is very low, as this diagnosis is rarely reported following cardiac procedures in children. While some reports were published worldwide on isolated chylopericardium after cardiac surgeries for diverse reasons, it has never been reported after repair for partial anomalous pulmonary venous return. In addition, management of this diagnosis ends up being surgical with minimal concentration on medical treatment which proved unsuccessful. We present a medical approach with corticosteroids as an effective method to treat isolated chylopericardium. CASE PRESENTATION: In this manuscript, we present an approach to treat isolated post-operative chylopericardium in a child following repair of partial anomalous pulmonary venous return. Chylous drainage responded to corticosteroids and completely ceased. There was no need for surgical intervention. CONCLUSION: Until now, isolated chylopericardium has never been reported to occur with partial anomalous pulmonary venous return repair. A review of the literature showed that most patients follow a conservative approach consisting of diuretics and non-steroidal anti-inflammatory agents with some of them undergoing surgical re-intervention. With future research on the topic still needed, we hope that this will encourage physicians worldwide to consider administering a trial of corticosteroids as an option to treat chylopericardium.

RESUMO

BACKGROUND: The overall 5-year survival of lung cancer remains dismal despite the current treatment regimens. Testing for driver mutations has become routine practice for oncologists due to the presence of targeted therapy readily available for patients. Deep targeted sequencing through next generation sequencing (NGS) is an adequate methodology to detect mutations at multi-genetic levels. The molecular pathology of non-small cell lung cancer (NSCLC) is poorly understood in the Middle East and, to date, no other reports have been published on deep targeted sequencing of lung adenocarcinoma (LUAD) tissues. METHODS: Deep targeted sequencing using TruSeq Amplicon Cancer panel of 48 genes was performed on 85 formalin-fixed paraffin-embedded tissues from patients with LUAD who were treatment-naive at the time of the collection. Variants with an allele frequency higher than 10% were retained. RESULTS: Variant calling identified a total of 2,455 variants of which missense mutations were the most frequent (75.6%). All of our samples showed at least one mutation in one of the 10 most commonly mutated genes with FLT3 being the gene with the highest mutation rate (67%). TP53, KRAS and STK11 were the second, third and fourth most commonly mutated genes, respectively while EGFR mutation rate reached 22.4%. CONCLUSIONS: To the best of our knowledge, this is the first hot spot profiling study on patients from this area. The frequencies of mutated genes presented in our study showed similarity to other reported outcomes. At least one mutation was detected in our cohort of LUAD.

RESUMO

Lung cancer remains a major cause of cancer mortality with a 5-year survival in advanced stages around 4%. Platinum-based chemotherapy was routinely used as the standard of care in patients with advanced nonsmall cell lung cancer, but it is being progressively replaced by targeted molecular therapy. One of the molecular aberrations harbored by lung adenocarcinoma is the epidermal growth factor receptor (EGFR). A large ethnic variation has been reported in the prevalence of EGFR mutations in patients with lung adenocarcinoma. Data regarding its prevalence from the Middle East area remains limited. This paper aims at reviewing the data available for the prevalence of this mutation in the Middle Eastern patient population and comparing it with other reported series.

RESUMO

Background: Burnout syndrome (BOS) is defined as a work-related psychological state characterized by emotional exhaustion, depersonalization, and low sense of personal accomplishment. Despite the extensive data on physician burnout, studies assessing the prevalence of burnout among oncologists in the Middle East and especially Lebanon are lacking. Our main objective was to determine this prevalence as well as identify potential factors associated with the development of burnout. Methods: This was a cross-sectional study conducted among medical, surgical, and radiation oncologists attending several Continuing Medical Education (CME) activities in Lebanon over the course of a three month period. Participants were asked to complete a self-administered questionnaire composed of socio-demographic and work characteristics, as well as the Maslach Burnout Inventory- Human Service Survey (MBI-HSS). Results: A total of 51 oncologists completed the survey. Medical oncologists constituted the majority (84.3%), followed by surgical oncologists (9.8%) and radiation oncologists (5.9%). Approximately 47.1% of our sample had a high burnout level in at least one of the domains. 33.3% of oncologists exhibited high emotional exhaustion (EE) scores, 19.6% demonstrated low personal accomplishment (PA) scores, and 13.7% displayed high depersonalization (DP) scores. There was no statistically significant association between overall burnout level and any of the demographic or work characteristics. However, age was significantly associated with EE (p=0.03), while DP scores were significantly associated with the number of patients seen daily (p=0.028). Conclusion: Burnout is common among cancer professionals in Lebanon. Future research is needed to explore the problem in depth and suggest effective preventive approaches.

RESUMO

INTRODUCTION: Accurate evaluation of estrogen and progesterone receptors and HER2 is critical when diagnosing invasive breast cancer for optimal treatment. The current evaluation method is via immunohistochemistry (IHC). In this paper, we compared results of ER, PR, and HER2 from microarray gene expression to IHC in 81 fresh breast cancer specimens. METHODS: Gene expression profiling was performed using the GeneChip Human Genome U133 Plus 2.0 arrays (Affymetrix Inc). Immunohistochemical staining for estrogen receptor, progesterone receptor, and HER2 status was performed using standard methods at a CAP-accredited pathology laboratory. Concordance rates, agreement measures, and kappa scores were calculated for both methods. RESULTS: For ER, Kappa score was 0.918 (95% CI, 0.77.3-1.000) and concordance rate was 97.5% (95% CI, 91.4%-99.7%). For PR, Kappa score was 0.652 (95% CI, 0.405-0.849) and concordance rate was 86.4% (95% CI, 77%-93%). For HER2, Kappa score was 0.709 (95% CI, 0.428-0.916) and concordance rate was 97.5% (95% CI, 91.4%-99.7%). CONCLUSION: Our results are in line with the available evidence with the concordance rate being the lowest for the progesterone receptor. In general, microarray gene expression and IHC proved to have high concordance rates. Several factors can increase the discordance rate such as differences in sample processing.

RESUMO

The objective of the study was to analyze the frequency and severity of vocal tract symptoms in patients on statins. A total of 73 patients were enrolled in this study, 44 patients who were taking statins and 29 controls not taking statins. The severity and frequency of vocal tract discomfort was assessed using the Vocal Tract Discomfort scale. The most frequent vocal tract symptom in patients on statins was dryness followed by tightness and lump sensation. The difference in the mean of the total score and in the mean frequency of any vocal tract symptom was not significant between patients taking statins and controls. The most severe (highest mean values) vocal tract symptom in patients taking statins also was dryness followed by tightness and lump sensation. The difference in the mean of the total score and in the mean severity of any vocal tract symptom between patients taking statins and controls was not significant. This study failed to demonstrate a higher prevalence or severity of vocal tract symptoms in patients receiving statins. Despite the lack of a significant difference in the means of vocal tract discomfort symptom frequency and severity, this study carries clinical significance when considering that a higher prevalence and severity of vocal tract discomfort symptoms should alert physicians to the possible development of statin-induced myotoxicity in the laryngopharyngeal complex.

RESUMO

BACKGROUND: Follicular dendritic cell sarcoma (FDCS) is an extremely rare malignant tumor caused by proliferation of antigen-presenting follicular dendritic cells. The tumor most commonly arises in lymph nodes, with fewer than 30% of cases originating in extranodal sites. CASE PRESENTATION: We report the case of a 39-year-old previously healthy male patient who presented with paraneoplastic pemphigus in the setting of a large intraperitoneal mass with no associated lymphadenopathy. The biopsy results showed a cellular proliferation of mildly to moderately atypical oval-to-spindle-shaped cells admixed with a variably dense lymphoplasmacytic infiltrate suggestive of FDCS versus inflammatory myofibroblastic tumor. A pathology review following total resection of the abdominal mass confirmed the diagnosis of FDCS. The tumor cells showed positivity for CD35, CD21, CD45, and CD68, negative ALK staining, and limited smooth muscle actin immunoreactivity. The surgery was complicated by severe pneumonia and acidosis, resulting in a prolonged ICU stay and death. CONCLUSION: It is essential to maintain a high index of suspicion for FDCS and include it in the differential diagnosis of a spindle cell neoplasm, especially in the setting of paraneoplastic pemphigus.

RESUMO

OBJECTIVE: This study aimed to investigate the effect of hormonal therapy (HRT) on voice in a group of menopausal women, taking into consideration body mass index (BMI) as a confounding factor and its potential role as a substitute for HRT. SUBJECTS AND METHODS: A total of 53 menopausal women, 34 not on HRT and 19 on HRT, were recruited. Demographic variables included age, gender, smoking, and BMI. All subjects were asked about the presence or absence of the following symptoms: hoarseness, deepening of the voice, pitch breaks, throat clearing, dryness in the throat, and vocal fatigue. Acoustic analysis was performed, and Voice Handicap Index-10 was also completed. RESULTS: The mean BMI was 25.90 ± 5.39 and 25.77 ± 4.26 in patients on HRT and not on HRT, respectively. There was no statistical difference in the Voice Handicap Index-10 score and the prevalence of any of the phonatory symptoms in menopausal women not on HRT compared with menopausal women on HRT. However, menopausal women not on HRT had significantly lower habitual pitch than those on HRT (P value of 0.022). On the other hand, the jitter was significantly higher in those on HRT (P value of 0.033). CONCLUSION: Hormonal therapy has an impact on the habitual pith in menopausal women with comparable BMI. Those on HRT have a higher habitual pitch than those not on HRT.
