RESUMEN
Endobronchial tuberculosis (EBTB) is characterized by tuberculosis infection of the tracheobronchial tree. It has variable presentation but tumorous growth-like presentation in bronchus is very rare. The clinical and radiological features are non-specific, which creates a diagnostic dilemma. Bronchoscopy and biopsy of the lesion are mandatory to confirm the diagnosis. In this case series, we are presenting three unique cases of endobronchial growth diagnosed as EBTB after biopsy and evaluation of bronchoalveolar lavage (BAL) with cartridge-based nucleic acid amplification test (CBNAAT) and other ancillary investigations for tuberculosis. Four patients presented to the outpatient department with non-specific symptoms of fever, cough, hoarseness of voice, and hemoptysis. They were evaluated with chest radiograph (CXR), contrast-enhanced computed tomography (CECT) thorax, and bronchoscopy. Bronchoscopy revealed growth in the bronchus in all three cases. A biopsy was taken and BAL was performed. All cases turned out to be EBTB in histopathological examination and BAL CBNAAT. They were treated with anti-tubercular drugs and all responded well to treatment. Endobronchial tuberculosis presenting as tumorous growth in the tracheobronchial tree is rare. There should be a high index of suspicion while dealing with patients with non-specific clinical and radiological features of tuberculosis. EBTB can be misdiagnosed as malignancy in most cases. Therefore, it should be kept as a differential diagnosis while encountering a mass lesion in the trachea or bronchus during bronchoscopy.
RESUMEN
Background Inflammatory markers are elevated in chronic obstructive pulmonary disease (COPD) and can be quantified to detect severity, prognosis, mortality risk, and response to treatment. However, the estimation costs are high. The blood neutrophil-to-lymphocyte ratio (NLR) and eosinophil levels are emerging as biomarkers in COPD, yet there is a paucity of data. Aim and objectives This study was designed to elucidate the roles of the NLR and eosinophil levels in smokers and non-smokers with stable COPD male subjects, correlating them with lung functions. Materials and methods A prospective observational clinical study was conducted from January to June 2023, after receiving approval from the Institutional Ethics Committee, on 73 COPD patients aged 30-60 years who gave voluntary informed consent. Complete blood counts and spirometry were performed. Patients with a forced expiratory volume in one second (FEV1) % predicted <70% and an FEV1/forced vital capacity (FVC) % <70% based on the pulmonary function test (MIR Spirolab) were included. They were further divided into mild (n=10), moderate (n=27), severe (n=26), and very severe (n=10) categories as per the Global Initiative for Chronic Obstructive Lung Disease (GOLD) guidelines. Subjects were also categorized into smoker (n=45) and non-smoker (n=28) groups. The complete blood count was analyzed using an automated analyzer (Beckman Coulter). Analysis was also carried out with an NLR of more or less than three. A P-value of less than 0.05 was considered significant. Results Smokers constituted 61.65% (n=45) of the subjects, and non-smokers 38.35% (n=28). Among smokers, 17.78% had very severe airflow obstruction. In all COPD subjects (n=73), lymphocytes, eosinophils, and lung functions were lower in the group where the NLR was greater than three. NLR in smokers (3.52±1.43) was higher than in non-smokers (3.39±0.94). In non-smokers (n=28), blood eosinophils and lymphocytes were elevated. In smokers (n=45), blood neutrophils, monocytes, and basophils were increased. Smokers showed a non-significant increase in RBC, mean corpuscular volume (MCV), and mean corpuscular hemoglobin (MCH). Neutrophils, monocytes, eosinophils, and NLR increased with disease severity. NLR negatively correlated with FEV1 (r=-0.350, p=0.034) and positively with pack-years (r=0.546, p<0.001) in smokers. NLR negatively correlated with eosinophils, FVC, FEV1/FVC, and FEV1 % predicted. In all COPD subjects (n=73), NLR negatively correlated with blood eosinophils (r=-0.184, p=0.12), BMI, and lung functions. Conclusion NLR is elevated in COPD subjects and can serve as a marker of inflammation and a predictor of the risk and severity of airflow limitation. NLR correlates both positively and negatively with pack-years and lung functions, respectively.
RESUMEN
BACKGROUND: Restless legs syndrome (RLS) is a common sensorimotor disorder during pregnancy. The purpose of this study was to assess the prevalence of RLS and explore the associated risk factors and outcomes in Omani women in the first and third trimester and at 2-week postpartum. MATERIALS AND METHODS: This cross-sectional study included 305 pregnant women visiting four health centers in Muscat between May 2018 and October 2020. A structured questionnaire was used and data were collected through review of electronic records and face-to-face interviews. The International RLS Study Group criteria were used to diagnose RLS. Participants were interviewed during their first trimester, their third trimester, and at their 2-week postpartum visit. Results were presented as means and standard deviations or percentages, as appropriate. To assess the association between RLS and various variables, unpaired t-test or McNemar's test were used, as appropriate. RESULTS: The mean age at baseline was 29.8 ± 5.28 years. The prevalence of RLS was significantly higher in the third trimester (41.0%) than in the first trimester (15.7%) and postpartum period (15.1%) (P < 0.001), although there was no significant difference in severity. Family history and personal history of RLS were the only independent correlates of RLS (P < 0.001 and 0.002, respectively). No associations were noted with pregnancy and neonatal outcomes or other comorbidities, including anemia. However, there was a significant relationship between the development of RLS and weight gain during pregnancy (P = 0.023). CONCLUSION: One in six pregnant Omani women may be at risk of RLS during the first trimester, while one in 2-3 may be at risk in the third trimester, particularly those with a personal or family history of RLS and those who gain >12 kg during pregnancy.
RESUMEN
OBJECTIVE: To determine the efficacy of simple needle aspiration in the management of primary spontaneous pneumothorax. Not all patients with pneumothorax require intercostal tube drainage (ICTD). Some patients can be managed conservatively by simple needle aspiration of air from pleural space. It is a cheap and easy alternative to ICTD which can be done on out patient basis. MATERIALS AND METHODS: All patients of spontaneous pneumothorax presenting for the first time were included in this study, after obtaining baseline investigations like chest X-ray, ECG, serum creatinine, blood sugar etc. They were managed by ICTD or simple needle aspiration. Chest X-ray was done 6 hours after the procedure (ICTD), 24 hours after aspiration and prior to ICTD removal or before hospital discharge. Patients who had undergone simple needle aspiration were allowed to go home following a few hours of observation after explaining the warning symptoms and the need for reevaluation after 24 hrs, if prompt follow-up could be ensured otherwise they were admitted along with patients undergoing ICTD. RESULTS: Eighty two patients of spontaneous pneumothorax were included in this study during a-period of 12 months (May- 04 to April - 05). Out of these 40 (49%) patients were managed by ICTD, 42 (51%) patients were subjected to simple needle aspiration. Thirty two (76%) patients responded to simple needle aspiration while the remaining 10 patients required ICTD finally. There were no complications in the patients managed by simple needle aspiration; they had less chest pain and lesser duration of hospital stay. CONCLUSION: Spontaneous pneumothorax may be managed by simple needle air aspiration primarily, unless contraindicated (tension pneumothorax), or in patients requiring mechanical ventilation. For symptomatic patient it is the recommended procedure.
