Torous VF, Ly A. Correlation between cytology Oil Red O staining and lung biopsy specimens: utility of the lipid-laden macrophage index. J Am Soc Cytopathol 2022; 11:226-233. [PMID: 35597768 DOI: 10.1016/j.jasc.2022.04.005] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/20/2022] [Revised: 04/07/2022] [Accepted: 04/14/2022] [Indexed: 06/15/2023]
Abstract
INTRODUCTION Oil Red O staining is used for enumeration of the lipid-laden macrophage index (LLMI) as a surrogate for aspiration. As part of quality improvement efforts aimed at optimizing resource utilization, the utility of this stain in current cytopathology practice was re-evaluated. The objective of this study was to explore the clinical utility of Oil Red O staining in bronchoalveolar lavage (BAL) samples by correlating the LLMI with findings in concurrent histologic tissue samples. MATERIALS AND METHODS Lung transbronchial biopsy specimens that suggested aspiration that were submitted with concurrent BAL cytology samples were retrieved. Lung tissue biopsies were reviewed for the presence of foamy alveolar macrophages (graded as 0, 1+, and 2+), foreign material, and giant cells. The concurrent BAL was reviewed with consensus determination of the LLMI. RESULTS A total of 53 cases were identified. On histology, 13 cases (24.5%) were found to have no foamy alveolar macrophages, 23 cases (43.4%) were found to have 1+ foamy alveolar macrophages, and 17 cases (32.1%) were found to have 2+ foamy alveolar macrophages. Six cases (11.3%) were found to have foreign material, and 10 cases (18.9%) were found to have multinucleated giant cells. The average LLMI score was 16, with 44 (83.0%) in the low range (LLMI <40) and 9 (17.0%) in the intermediate range (LLMI of 40-90). CONCLUSIONS None of the cases in our study had an LLMI that exceeded the cutoff value for which aspiration would be suspected. We found no correlation of the LLMI with lung biopsies that suggested aspiration.

Abstract
BACKGROUND The causal relationship between asthma and gastroesophageal reflux disease (GERD) is unknown in children. METHODS The Korean Health Insurance Review and Assessment Service-National Sample Cohort 2002-2013 was used. The population age <15 years was selected. In study I, 86,096 asthmatic children were 1:1 matched with 86,096 control I participants. In study II, 532 GERD children were 1:2 matched with 1064 control II participants. The stratified Cox proportional hazard ratios for GERD in patients with asthma (study I) and asthma in patients with GERD (study II) were analyzed. RESULTS In total, 0.7% (583/86,096) of the asthma group and 0.5% (430/86,096) of the control I group had GERD (P < 0.001). The asthma group demonstrated a 1.36 times higher HR for GERD than the control I group (95% CI = 1.20-1.54, P < 0.001). Subgroup analyses according to age and sex showed consistent results. In total, 15.0% (80/532) of the GERD group and 10.0% (106/1,064) of the control II group had asthma (P < 0.001). The GERD group showed a 1.62-fold higher HR for asthma than the control II group (95% CI = 1.21-2.18, P < 0.001). CONCLUSION GERD and asthma demonstrated a bidirectional relationship in children.

Abstract
Asthma is one of the most common and chronic diseases of adults and creates substantial health problems. The disease must be diagnosed appropriately, its severity assessed, and treatment prescribed that matches the level of severity. Patient education in self-management techniques and attention to the problems of adherence are essential for long-term management. Comorbid conditions should be suspected and treated when asthma becomes difficult to control. Asthma in the elderly is a challenging but frequent problem that requires particular attention to controlling the causes of excessive morbidity and mortality. All health care professionals have an important role in controlling this common disease.

Abstract
OBJECTIVES Refluxed gastric material aspirated into the lungs is an important cause of acute and chronic pulmonary disease. Currently, the presence of fat-laden macrophages (FLM) in tracheobronchial secretions of children is a conventional marker for reflux aspiration. However, this assay is limited by its apparent lack of specificity. The aim of this study was to reevaluate the role of this assay in diagnosing reflux aspiration. METHODS The tracheal aspirates of sixty-four consecutive children with clinically significant gastroesophageal reflux undergoing upper gastrointestinal endoscopy under general anesthesia, and 34 other children from the routine operative schedule were evaluated. Both groups were further subdivided on the basis of presence or absence of associated respiratory symptoms. After intubation, tracheal aspirates were collected, fixed, and stained for FLM. By grading the amount of intracellular fat present, a semiquantitative lipid index was computed. Tracheal aspirates with a lipid index of 100 or greater were considered positive. RESULTS Twenty-four of the 64 children with reflux symptoms and 14 of 34 children without reflux symptoms were positive for FLM. Sixteen of 37 children with both gastroesophageal reflux and respiratory symptoms and 10 of 26 children negative for both tested positive for FLM. The mean lipid index of the subgroup of children with both reflux and respiratory symptoms was not significantly different from that of the subgroup that was negative for both conditions. Despite computing a semiquantitative lipid index, an index of 100 or greater only had a sensitivity of 38% and specificity of 59%. CONCLUSION Assay of FLM in the tracheal aspirates of children considered at risk of reflux aspiration is not a sensitive or specific as a marker for reflux aspiration.

Abstract
The viral etiology of frequently recurring respiratory tract infection (FRRI) in children aged <2 years was studied. Altogether, 329 children were followed from 2 to 24 months of age in the Finnish Otitis Media Cohort Study. Children with FRRI were defined as having > or =9 episodes of upper respiratory tract infection (URI) and/or > or =4 episodes of acute otitis media during follow-up. Nasopharyngeal aspirates, middle ear fluid specimens, and serum samples were analyzed for 8 common respiratory viruses. Of 1358 URI episodes, 642 (47%) occurred in the 78 children with FRRI. At least 1 virus was associated with 62% of these episodes, whereas the corresponding figure for children without FRRIs was 54%. The frequency of different viruses was similar in both groups, but the relative proportion of rhinovirus infections was slightly higher among children with FRRI. In conclusion, a specific viral etiology does not explain the excess of URI episodes in children with FRRI.

Abstract
BACKGROUND Children with ear, nose and throat disorders are believed to have a high incidence of pathologic gastroesophageal reflux (GER). This study was designed to establish the frequency and ratio of pathologic GER in the development of chronic tubotympanal disorders. METHODS Twenty-seven children with chronic tubotympanal disorders (mean age, 2 to 13 years; average age, 6.8 years) underwent 24-hour continuous pH monitoring. Fourteen of the examined patients had secretory otitis, whereas 13 patients had recurrent otitis. From each 24-hour pH monitoring, 12-hour daytime and nighttime periods were selected. Eleven patients were tested using simultaneous dual pH monitoring (distal and proximal pH monitoring). RESULTS Fifteen (55.6%) of 27 patients had pathologic GER. The authors did not find a relation between pathologic GER and different types of ear disorders. Daytime pH monitoring yielded significantly more episodes of reflux than did nighttime monitoring. The reflux index was substantially higher during the day. In the current study, distal pH monitoring showed that 6 of 11 patients had pathologic GER, whereas proximal pH monitoring showed that only only 3 of 11 patients had pathologic GER. CONCLUSIONS The authors recommend that a pH study be performed in children with chronic tubotympanal disorders when standard treatment is ineffective. The method of choice for the diagnosis of pathologic GER in patients with chronic tubotympanal disorders should be pH monitoring of the esophagus and throat.

Abstract
Gastroesophageal reflux (GER) is one of the three most common causes of chronic cough in children, along with postnasal drip syndrome and asthma. There may be no gastrointestinal symptoms up to 50-75% of the time. GER plays a causative role in chronic cough, asthma without allergy and posterior laryngitis. GER most commonly provokes coughing by stimulating an esophageal-bronchial reflex and by irritating the lower respiratory tract by microaspiration. Twenty-four-hour pH monitoring of the distal esophagus is the most accurate diagnostic method for children with suspected GER and it helps to establish a temporal correlation between cough and GER. The first step of the treatment is the association of postural and dietetic measures and medications (prokinetics and antacids). The length of the treatment is a minimum of 3 months up to the age of walking. Surgical treatment must be reserved for the failure of medical treatment. The benefits of minimally invasive surgery are evident in children with chronic cough, who have a faster recovery with fewer complication than after open surgery.
