Congenital vallecular cysts are rare. In this report, four infants having vallecular cysts encountered over a six-year period from 1992 to 1997 were reviewed. All of them presented with upper aerodigestive tract symptoms. Marsupialization was performed in three of them and CO2 laser excision was performed in the fourth patient. There was no recurrence of the cyst in any patient. One of them also had co-existing laryngomalacia. The degree of airway collapse caused by laryngomalacia improved after cyst removal. The laryngomalacia resolved spontaneously. Cyst fluid culture was performed in one of the patients and yielded Staphylococcus aureus but there was no other definite indicator of infection. Staphylococcus aureus could also be isolated in the respiratory tract from two of the other patients.

Staphylococcus aureus is the predominant pathogen in acute suppurative parotitis. Although anaerobic bacteria are prevalent in the normal oral and upper respiratory tract flora and frequently are involved in oral and facial infections, they have seldom been isolated from patients with suppurative parotitis. It may be that a role for anaerobes in parotitis has not been documented because of inadequate specimen transport or anaerobic culture techniques. We describe two cases of acute suppurative parotitis in which cultures yielded anaerobic bacteria. In one case, no aerobes were isolated; in the other, the anaerobe was the predominant organism numerically.

ABSTRACT Drug-induced airway hematoma is a very rare condition. The incidence of hemorrhage with anticoagulants is 6.8%. We hereby present the case reports of two such cases. Both patients presented with dysphagia and throat pain. One was on warfarin and the other was on aspirin. Examination revealed laryngeal and retropharyngeal hematoma respectively. Discontinuation of drugs and reversal of anticoagulation improved the symptoms. In the second case, retropharyngeal hematoma was drained. These cases highlight the importance of suspecting this entity in patients on drugs, especially anticoagulants who present with upper aerodigestive tract symptoms. Timely intervention and reversal of coagulopathy can save the patients. How to cite this article Divya GM, Dahiya V, Ramachandran K, Muhammed F. Drug-induced Airway Hematoma.

Cross Linkage

Penicillin exerts the activity to inhibit the peptide cross linkage between each polysaccharide backbone at the final stage of wall-peptidoglycan biosynthesis of bacteria. Morphologically, alterations of the septal wall and mesosome in gram-positive bacteria, which were occurred in early time after treatment with penicillin, have been observed. In this experiment, these alterations were cytochemically investigated by means of silver-methenamine staining after periodate oxidation, which is applied for detection of localization of wall mucopolysaccharide.Staphylococcus aureus strain 209P treated with 100 u/ml of penicillin G was divided into two aliquotes. One was fixed by Kellenberger-Ryter's OSO4 fixative at 30, 60 and 120 min after addition of the antibiotic, dehydrated through alcohol series, and embedded in Epon 812 (Specimen A). The other was fixed by 21 glutaraldehyde, dehydrated through glycolmethacrylate series and embedded in glycolmethacrylate mixture, according to Bernhard's method (Specimen B).

Crude Methanol Extract

The antibacterial activity of three Cupressaceae plants (Thujaoccidentalis,ThujaorientalisandChamaecyparisobtusa) was tested against three bacteria using the agar diffusion method. The ether and ethylacetate fraction of crude methanol extract from the three plants showed potent antibacterial activity against the tested microorganisms. The result showed that Staphylococcus aureus revealed the most sensitivity among the tested bacteria. Thujaoccidentalisether fraction and Thujaorientalis hexane fraction exhibited the highest antibacterial activity against Staphylococcus aureus. E. coli was shown the highest MIC values compared to the other two tested bacteria, which indicates the lowest antibacterial activity against the bacterium. This study promises an interesting future for designing a potentially active antibacterial agent from the three Cupressaceae plants.

Atypical Clinical Presentation

Background: Laryngopharyngeal reflux (LPR) is a common disease in otolaryngology characterized by an inflammatory reaction of the mucosa of the upper aerodigestive tract caused by digestive refluxate enzymes. LPR has been identified as the etiological or favoring factor of laryngeal, oral, sinonasal, or otological diseases. In this case series, we reported the atypical clinical presentation of LPR in patients presenting in our clinic with reflux. Methods: A retrospective medical chart review of 351 patients with LPR treated in the European Reflux Clinic in Brussels, Poitiers and Paris was performed. In order to be included, patients had to report an atypical clinical presentation of LPR, consisting of symptoms or findings that are not described in the reflux symptom score and reflux sign assessment. The LPR diagnosis was confirmed with a 24 h hypopharyngeal-esophageal impedance pH study, and patients were treated with a combination of diet, proton pump inhibitors, and alginates. The atypical symptoms or findings had to be resolved from pre- to posttreatment. Results: From 2017 to 2021, 21 patients with atypical LPR were treated in our center. The clinical presentation consisted of recurrent aphthosis or burning mouth (N = 9), recurrent burps and abdominal disorders (N = 2), posterior nasal obstruction (N = 2), recurrent acute suppurative otitis media (N = 2), severe vocal fold dysplasia (N = 2), and recurrent acute rhinopharyngitis (N = 1), tearing (N = 1), aspirations (N = 1), or tracheobronchitis (N = 1). Abnormal upper aerodigestive tract reflux events were identified in all of these patients. Atypical clinical findings resolved and did not recur after an adequate antireflux treatment. Conclusion: LPR may present with various clinical presentations, including mouth, eye, tracheobronchial, nasal, or laryngeal findings, which may all regress with adequate treatment. Future studies are needed to better specify the relationship between LPR and these atypical findings through analyses identifying gastroduodenal enzymes in the inflamed tissue.
