A Web-Based Dynamic Nomogram to Predict the Risk of Methicillin-Resistant Staphylococcal Infection in Patients with Pneumonia.

The aim of this study was to create a dynamic web-based tool to predict the risks of methicillin-resistant spp. (MRS) infection in patients with pneumonia. We conducted an observational study of patients with pneumonia at Cho Ray Hospital from March 2021 to March 2023.

Indoor Aeroallergen Sensitization and Associated Factors in Hospitalized Children with Asthma Exacerbations.

Background: Allergic asthma represents the most popular phenotype of childhood asthma and is characterized by eosinophilic airway inflammation associated with specific immunoglobulin E (IgE) antibodies sensitization to various allergens, as evidenced by serology or skin prick test. Sensitization to indoor aeroallergens is associated with severe asthma and severe asthma exacerbations.

Objective: This study aimed to identify the prevalence of aeroallergen sensitization and its associated factors in children with an asthma exacerbation in Vietnam.

Prognostic Significance of PD-L1 Expression and Standardized Uptake Values in the Primary Lesions of Stage IV Adenocarcinoma Lung Cancer.

Background: This study evaluated the prognostic ability of F-fluorodeoxyglucose (F-FDG) positron emission tomography (PET)/computed tomography (CT) in patients with stage IV adenocarcinoma lung cancer to detect protein death-ligand 1 (PD-L1) expression levels.

Methods: In total, 86 patients with stage IV adenocarcinoma lung cancer underwent F-FDG PET/CT imaging and PD-L1 expression evaluation before treatment from February 2019 to November 2020 at Bach Mai Hospital, Hanoi, Vietnam. The assessed patient characteristics in this study included sex, age, smoking status, epidermal growth factor receptor () mutation, PD-L1 expression level, survival status, tumor, node, and metastasis (TNM) stage, and metastasis locations.

Cavitary lung disease in hospitalized patients: Differences between melioidosis and tuberculosis.

To differentiate cavitary lung lesions caused by melioidosis and tuberculosis is challenging, especially in endemic countries. A study with a matched-sampling method (16 cavitary pulmonary melioidosis 16 cavitary pulmonary tuberculosis) showed characteristics of bacterial infection more obvious and severe in the melioidosis patients, which were useful to distinguish two conditions.

Awareness and preparedness of healthcare workers against the first wave of the COVID-19 pandemic: A cross-sectional survey across 57 countries.

Background: Since the COVID-19 pandemic began, there have been concerns related to the preparedness of healthcare workers (HCWs). This study aimed to describe the level of awareness and preparedness of hospital HCWs at the time of the first wave.

Methods: This multinational, multicenter, cross-sectional survey was conducted among hospital HCWs from February to May 2020.

Pulmonary mucoepidermoid lung carcinoma in pediatric confused with asthma.

Pulmonary mucoepidermoid carcinoma (PMEC) is an extremely rare tumor of the respiratory system. The clinical presentation of PMEC is variable and nonspecific, including cough, hemoptysis, and wheezing, and may mimic other symptoms of pneumonia or asthma. Here, we present a case of PMEC in a 12-year-old male who was diagnosed with and treated for asthma for 2 years.

Pleuropulmonary blastoma (type III) in a two-year-old: A case report.

Pleuropulmonary blastoma is a rare, aggressive, malignant tumor of the lungs or pleura that primarily affects children. Pleuropulmonary blastoma is classified into 3 types based on morphology, including cystic (type I), mixed (type II), or solid (type III). These morphological types correlate with prognosis.

Mucoepidermoid lung carcinoma in a pediatric patient confused with pneumonia.

Mucoepidermoid carcinoma (MEC) is a common type of salivary gland malignancy; however, rarely, MEC can arise from the lung. This disease has a non-specific presentation and is often overlooked. Histologically, MEC can be classified into low-grade and high-grade forms.

Exhaled Nitric Oxide as a Surrogate Marker for Obstructive Sleep Apnea Severity Grading: An In-Hospital Population Study.

Purpose: Our study aimed to evaluate the relationship between exhaled nitric oxide (eNO) markers and obstructive sleep apnea (OSA) severity and verify the changes in eNO profiles among mild, moderate, and severe OSA subgroups.

Methods: This study was a cross-sectional and in-hospital population-based study. We investigated 123 OSA patients (17 mild, 23 moderate and, 83 severe OSA) in the department of respiratory diseases.

Central versus peripheral lesion on chest X-Ray: A case series of 31 endobronchial tuberculosis patients with negative sputum smears.

Background: Clinical characteristics of endobronchial tuberculosis (EBTB) patients whose sputum smears were negative have not been elucidated yet.

Method: EBTB patients with negative sputum smears were documented retrospectively at the outpatient pulmonary clinic from late 2015 to early 2019.

Results: We described the characteristics of 31 EBTB patients with negative sputum smears.

The first case of spp. pneumonia reported in Vietnam.

A respiratory fungal infection is a severe clinical problem caused by endemic or opportunistic fungi. Although pulmonary fungal infections may be associated with no symptoms, the patient may also present with cough, fever, chest pain, and hemoptysis. spp.

Stepping down therapy for well-controlled mild asthma: an experience from University Medical Center at Ho Chi Minh City.

Background: Stepping down treatment for well-controlled mild asthma is challenging to clinicians. The step-down strategy using regularly-intermittent low-dose inhaled corticosteroid has been applied at the University Medical Center (UMC) of Ho Chi Minh City, called as "UMC" approach.

Objective: This study aimed to evaluate the efficiency of UMC step-down strategy in well- controlled mild asthma.

Aberrant right subclavian artery and bibasilar bronchiectasis: is there any association?

Dysphagia is the most common symptom in symptomatic patients with aberrant right subclavian artery (ARSA) and also the risk factor of aspiration, especially in elderly patients. We presented an 84 year-old female patient with dysphagia induced by the compression of ARSA to the adjacent structures. Recurrent pneumonia and bibasilar bronchiectasis were recorded in the association with ARSA.

Hilar asymmetry in endobronchial tuberculosis patients: An often-overlooked clue.

Background: Endobronchial tuberculosis (EBTB) is a challenging diagnosis because of its varied clinical and radiological manifestations. Hilar asymmetry on chest radiograph (CXR) may be found in patient with EBTB but is often overlooked, which may lead to delayed diagnosis.

Case Report: We present five cases with EBTB.

Allergic Bronchopulmonary Aspergillosis masquerading as recurrent bacterial pneumonia.

Allergic Bronchopulmonary Aspergillosis (ABPA) can be diagnosed in an asthmatic with suitable radiologic and immunological features. However ABPA is likely to be misdiagnosed with bacterial pneumonia. Here we report a case of ABPA masquerading as recurrent bacterial pneumonia.

A descriptive study of TB cases finding practices in the three largest public general hospitals in Vietnam.

Background: A project was implemented in 2010 to improve TB notification and TB screening and diagnostic routines in large general hospitals. The aims of present study was to assess baseline TB screening and diagnostic practices in the three largest general hospitals in Vietnam.

Objectives: To assess baseline TB screening and diagnostic practices in the three largest general hospitals in Vietnam.
