Background: Unilateral intratonsillar abscess (ITA) is an underreported, well-known complication of acute tonsillitis. The prevalence of unilateral ITA compared to peritonsillar abscess (PTA) is 1:14. However, bilateral ITA is an extremely rare entity, with only four cases reported thus far.

Objectives: To describe past cases and our experience, elaborating the diagnostic challenge and the surgical treatment for bilateral ITA.

Methods: We conducted a literature search in the PubMed database using the key words intra-tonsillar abscess, tonsillar abscess, bilateral tonsillar abscess, bilateral intra-tonsillar abscess and bilateral peritonsillar abscess. Our search was limited to the years 1980 to 2020.

Results: We found that only four cases of bilateral ITA were previously published. All were characterized by a delay in diagnosis with a median of 10 days (4–14 days), symmetrical oral cavity appearance, enlarged bilateral kissing tonsils, and subsequent treatment by surgical drainage/paracentesis. Respiratory compromise was a concern in most cases. Our patient was treated with bilateral quinsy tonsillectomy and had a prompt recovery.

Conclusions: Bilateral ITA is a rare, deceiving entity, with a diagnosis delay attributed to the symmetrical oral bulging. We present the fifth case reported and the first ever reported in a pediatric patient. We describe the assumed pathogenesis and the main characteristics among all five patients, emphasizing the important role of a high index of suspicion and appropriate imaging, guiding to proper diagnosis and treatment.

Background: Nasal polyps are three-dimensional structures arising from the mucosa of the upper airway. Due to their complexity, the reliability of single-layer cell cultures and animal systems as research models is limited.

Objectives: To evaluate the feasibility of an ex vivo organ culture of human polyps, preserving tissue structure and function.

Methods: Nasal polyps were excised during routine endoscopic sinus surgery for chronic rhinosinusitis and polyposis. Fresh tissue samples were used for pathological evaluation and for the preparation of 250–500 µm sections, which were incubated in culture media. Tissue viability was assessed by visualisation of cilia motility, measurement of glucose uptake, and an infectivity assay. Cytokine secretion was evaluated by enzyme-linked immunosorbent assay and real-time polymerase chain reaction before and after the introduction of steroids.

Results: Polyp tissue viability was retained for 2–3 days as demonstrated by cilia motility, glucose uptake and preserved cellular composition. Tissue samples maintained their capacity to respond to infection by herpes simplex virus 1 and adenovirus. Introduction of dexamethasone to cultured tissue samples led to suppression of interferon-g production.

Conclusions: The ex vivo nasal polyp organ culture reproduces the physiological, metabolic, and cellular features of nasal polyps. Furthermore, it shows a preserved capacity for viral infection and response to drugs. This system is a useful tool for the investigation nasal-polyps and for the development of novel therapies.

Background: Warm compresses are widely touted as an effective treatment for ocular surface disorders. Black tea compresses are a common household remedy, although there is no evidence in the medical literature proving their effect and their use may lead to harmful side effects. 

Objectives: To describe a case in which the application of black tea to an eye with a corneal epithelial defect led to anterior stromal discoloration; evaluate the prevalence of hot tea compress use; and analyze, in vitro, the discoloring effect of tea compresses on a model of a porcine eye.

Methods: We assessed the prevalence of hot tea compresses in our community and explored the effect of warm tea compresses on the cornea when the corneal epithelium’s integrity is disrupted. An in vitro experiment in which warm compresses were applied to 18 fresh porcine eyes was performed. In half the eyes a corneal epithelial defect was created and in the other half the epithelium was intact. Both groups were divided into subgroups of three eyes each and treated experimentally with warm black tea compresses, pure water, or chamomile tea compresses. We also performed a study in patients with a history of tea compress use. 

Results: Brown discoloration of the anterior stroma appeared only in the porcine corneas that had an epithelial defect and were treated with black tea compresses. No other eyes from any group showed discoloration. Of the patients included in our survey, approximately 50% had applied some sort of tea ingredient as a solid compressor or as the hot liquid.

Conclusions: An intact corneal epithelium serves as an effective barrier against tea-stain discoloration. Only when this layer is disrupted does the damage occur. Therefore, direct application of black tea (Camellia sinensis) to a cornea with an epithelial defect should be avoided.

 

Background: Comorbid depression may play an important role in non-compliance with medical treatment among patients with chronic illnesses. Glaucoma is a potentially blinding chronic disease requiring life-long commitment to medical therapy. Patient's failure to adhere to anti-glaucoma treatment may lead to disease progression and visual loss.

Objectives: To assess the prevalence of depressive symptoms in glaucoma patients and the association between these symptoms and non-compliance with anti-glaucoma therapy.

Methods: This was a cross-sectional observational study. Compliance with pharmacotherapy was assessed with the Morisky Medication Adherence questionnaire (eight items). Screening for depression was performed by means of the CES-D scale (Center for Epidemiologic Studies Depression scale). The association between depression and compliance rates was analyzed.

Results: The study group comprised 76 glaucoma patients; 19.7% of the subjects were classified as "non-compliant" (Morisky cutoff < 10) and 21.1% suffered from depression (CES-D cutoff ≥ 16). We found a similar level of non-compliance when comparing depressed with non-depressed glaucoma patients. However, a significant correlation was observed between the level of depression and the level of non-compliance (P = 0.04).

Conclusions: Our study revealed a similar rate of depression in glaucoma patients and the general Israeli population. The presence of depression was not associated with the presence of non-compliance, yet the level of depression was associated with the level of non-compliance.
