Epithelioid hemangioma (ALHE) on the tongue of an infant treated with oral corticosteroids: A case report and review of the literature.

Epithelioid hemangioma or angiolymphoid hyperplasia with eosinophilia (ALHE) is a rare benign vascular lesion presenting as multiple nodules on the head and neck. Surgery had been considered to be the best treatment modality for ALHE. We report the case of a 6-month-old boy with ALHE on his tongue that was treated successfully with oral prednisolone.

Remdesivir associated sinus bradycardia in patients with COVID-19: A prospective longitudinal study.

Background: Remdesivir is effective against SARS-Cov-2 with little evidence of its adverse effect on the cardiac system. The aim of the present study is investigating the incidence of bradycardia in COVID-19 patients treated with Remdesivir. Methods: This prospective longitudinal study was conducted in a tertiary center on COVID-19 patients for Remdesivir therapy. The objectives were to investigate the incidence of sinus bradycardia, and also the association between their demographics, underlying diseases, and the disease severity with developing bradycardia in COVID-19 patients treated with Remdesivir. Results: Of 177 patients, 44% were male. The mean (±standard deviation) age of patients was 49.79 ± 15.16 years old. Also, 33% were hospitalized due to more severe symptoms. Oxygen support was required for all hospitalized subjects. A total of 40% of the patients had comorbidities, with the most common comorbidity being hypertension. The overall incidence of bradycardia (heart rate<60 bpm) in patients receiving Remdesivir was 27%, of whom 70% had extreme bradycardia (heart rate <50 bpm). There was also a statistically significant reduction in heart rate after five doses of Remdesivir compared to the baseline heart rates. In the multivariable model, none of the covariates including age above 60 years, female sex, CRP>50 mg/L, O2 saturation<90%, underlying cardiovascular disease, hypertension and diabetes mellitus, and beta-blockers were associated with Remdesivir-induced bradycardia. No association was found between the COVID-19 severity indicators and bradycardia. Conclusion: As sinus bradycardia is a prevalent adverse cardiac effect of Remdesivir, it is recommended that all COVID-19 patients receiving Remdesivir, be evaluated for heart rate based on examination; and in the case of bradyarrhythmia, cardiac monitoring should be performed during administration to prevent adverse drug reactions.

Lung ultrasound for the diagnosis of cystic fibrosis pulmonary exacerbation.

BACKGROUND: High-resolution computed tomography (HRCT) is the gold standard for the evaluation of cystic fibrosis (CF) lung disease; however, lung ultrasound (LUS) is being increasingly used for the assessment of lung in these patients due to its lower cost, availability, and lack of irradiation. We aimed to determine the diagnostic performance of LUS for the evaluation of CF pulmonary exacerbation. METHODS: This cross-sectional study included patients with CF pulmonary exacerbation admitted to Masih Daneshvari Hospital, Tehran, Iran, from March 21, 2020 to March 20, 2021. Age, gender, and body mass index (BMI) of the patients were recorded. All patients underwent chest X-ray (CXR), HRCT, and LUS on admission. Pleural thickening, atelectasis, air bronchogram, B-line, and consolidation were noted in LUS and then compared with the corresponding findings in CXR and HRCT. Taking HRCT findings as reference, sensitivity, specificity, positive predictive value (PPV), negative predictive value (NPV), and diagnostic accuracy (DA) of LUS and CXR for the detection of each pulmonary abnormality were determined. RESULTS: Of the 30 patients included in this study, with a mean age of 19.62 ± 5.53 years, 14 (46.7%) were male. Of the 15 patients aged 2-20 years, BMI was below the 5th percentile in 10 (66.7%), within the 5-10 percentiles in 1 (6.7%), 10-25 percentiles in 3 (20%), and 25-50 percentiles in 1 (6.7%). The mean BMI for 15 patients > 20 years was 18.03 ± 2.53 kg/m2. LUS had better diagnostic performance compared to CXR for the detection of air bronchogram, consolidation, and pleural thickening (area under the receiver operating characteristic curve [AUROC]: 0.966 vs. 0.483, 0.900 vs. 0.575, and 0.656 vs. 0.531, respectively). Also, LUS was 100% and 96.7% specific for the diagnosis of pleural effusion and atelectasis, respectively. CONCLUSIONS: LUS appears to be superior to CXR and comparable with HRCT for the evaluation of CF pulmonary exacerbation, especially in terms of air bronchogram and consolidation detection. LUS can be used to lengthen the HRCT evaluation intervals in this regard or utilized along with HRCT for better evaluation of CF pulmonary exacerbation.

Telomere length assessment in blood leukocytes of patients with sarcoidosis.

BACKGROUND: Accelerated aging and telomere shortening have been studied in many chronic diseases such as interstitial pulmonary fibrosis and chronic obstructive pulmonary disease. Different studies have shown that patients with these diseases have shorter telomere lengths than controls; this can be a marker of the progression and outcome of the disease. So far, a few studies have been evaluated the telomere length in sarcoidosis. In this study we determine the telomere length in patients with sarcoidosis and compare it with control subjects. OBJECTIVE: Our aim is to compare telomere length in patients with sarcoidosis and normal population. Methods: We select 58 patients with sarcoidosis who were visited in the sarcoidosis clinic of Masih Daneshvari Hospital. 58 sex and age-matched (with±2 years) healthy control subjects were selected. Telomere length was measured by quantitative real time PCR as described by Cawthon on peripheral blood sample. The telomere repeat copy number (T) to single-gene copy number(S) ratio was calculated using the comparative Ct method. Results: The mean and standard deviation of telomere length in the patient and control group was 0.65 ± 0.05 and 0.72 ± 0.07 respectively. There was a statistically significant difference between the two groups. (P = 0.031). Conclusion: Sarcoidosis is an inflammatory disease that can involve many organs. Like other chronic diseases, aging phenomenon occurs in that; which led to decrease cellular and tissue telomere length. This article demonstrates shorter telomere length in Iranian sarcoidosis patients compared to normal population.

Distribution and Characteristics of Intrathoracic Lymphadenopathy in TB/HIV Co-Infection.

BACKGROUND: Intrathoracic Lymphadenopathy (ITLN) in Human Immunodeficiency Virus (HIV) infected patients may have various etiologies and prognoses. Etiologies of ITLN can be distinguished based on the distribution of enlarged lymph nodes. Sometimes tuberculosis (TB) is the first sign of underlying HIV infection. OBJECTIVES: We sought to determine ITLN distribution and associated pulmonary findings in TB/HIV co-infection using Computed Tomography (CT) scan. METHODS: In this retrospective, observational, cross-sectional study, chest CT scans of 52 patients with TB/HIV co-infection were assessed for enlarged intrathoracic lymph nodes (>10 mm in short axis diameter), lymphadenopathy (LAP) distribution, calcification, conglomeration, the presence of hypodense center and associated pulmonary abnormalities. LAP distribution was compared in TB/HIV co-infection with isolated TB infection. RESULTS: Mediastinal and/or hilar LAP were seen in 53.8% of TB/HIV co-infection patients. In all cases, LAP was multistational. The most frequent stations were right lower paratracheal and subcarinal stations. Lymph node conglomeration, hypodense center and calcification were noted in 25%, 21.4% and 3.5% of patients, respectively. LAP distribution was the same as that in patients with isolated TB infection except for the right hilar, right upper paratracheal and prevascular stations. All patients with mediastinal and/or hilar adenopathy had associated pulmonary abnormalities. CONCLUSION: All patients with TB/HIV co-infection and mediastinal and/or hilar adenopathy had associated pulmonary abnormalities. Superior mediastinal lymph nodes were less commonly affected in TB/HIV co-infection than isolated TB.
