Structural and inflammatory airway mucosal changes in non-asthmatic chronic cough could represent the cause or the traumatic response to repetitive coughing.
Coughing can be reflexly induced in man by reducing the chloride ion content of airway surface lining liquid (ASL).
Our findings suggest that paroxysmal coughing could account for such bleeding in some cases.
If combined with environmental or endogenous cough triggers, the cough reflex sensitization is predicted to cause excessive coughing.
These results suggest that coughing occurs in both temporal and extratemporal lobe epilepsy and may only be indicative of temporal lobe seizure onset if representing a regular semiologic element.
We suspect that the VPC-induced hemodynamic changes in the pulmonary circulation might be responsible for coughing in our patient.
Our findings suggest that airway inflammation associated with chronic cough, assessed on morphologic appearance and inflammatory cell counting in hematoxylin-eosin-prepared samples, may be due to the trauma of coughing, and the inflammation may be similar to that seen with diseases putatively thought to cause chronic cough.

What are the audiological findings in disorders of the tympanic membrane?5 answersAudiological findings in disorders of the tympanic membrane vary based on the specific condition. Retraction was the most common abnormality observed, with Grade I retraction being the most prevalent, followed by Tympanosclerosis. In cases of tensor tympani contraction, a low frequency mixed hearing loss was noted, with increased air conduction thresholds at 250 Hz by 22 dB and bone conduction thresholds by 10 dB. Patients with PLA2G6-associated neurodegeneration exhibited sensorineural hearing loss or auditory neuropathy spectrum disorder in 77% of cases. Additionally, patients with conductive hearing loss and intact tympanic membranes may require exploratory tympanotomy for accurate diagnosis and treatment, often revealing stapedial fixation as a common pathology.
Can epiretinal membrane cause headaches?4 answersEpiretinal membrane (ERM) primarily affects the retina, leading to vision issues like distortion and loss. While ERM is associated with visual symptoms, there is no direct evidence linking it to headaches in the provided contexts. ERM is commonly asymptomatic or causes mild visual disturbances. Studies focus on genetic associations, prevalence, surgical treatments, and risks of ERM, without mentioning headaches as a symptom or complication. Therefore, based on the available data, there is no indication that ERM directly causes headaches. Symptoms of ERM typically revolve around vision problems rather than headaches, suggesting that other factors may be responsible for headache occurrences.
What are the different mechanisms that lead to otitis media?5 answersOtitis media (OM) can be caused by various mechanisms. The pathogenesis of OM involves the interplay between infectious pathogens, host immunological status, environmental factors, and genetic predisposition. Otopathogens utilize host mucin production, phase variation, biofilm production, glycans, and neutrophil and eosinophilic extracellular traps to induce OM. Development of OM requires nasopharyngeal colonization by pathogens, overcoming the defense mechanisms of the immune system and middle ear mucosa. Complex interactions among bacteria, viruses, inflammatory cells, immune cells, and epithelial cells contribute to OM. Moraxella catarrhalis, a leading causative agent of OM, possesses multiple virulence factors that can activate host immune responses. These mechanisms collectively contribute to the development and progression of OM.
What are the most common causes of headache and cough?5 answersThe most common causes of headache and cough include primary cough headache, primary exercise headache, and secondary cough headache. Primary cough headache is characterized by an immediate headache that occurs with coughing, sneezing, straining, or other Valsalva maneuvers. Primary exercise headache, on the other hand, occurs with exertional effort and is often bilateral and pulsatile. Secondary cough headache is usually associated with structural lesions, such as Chiari malformation type I, and presents with posterior fossa symptoms/signs. Other causes of secondary cough headache include miscellaneous posterior fossa pathology, carotid or vertebrobasilar disease, and cerebral aneurysms. It is important to note that diagnostic neuroimaging is crucial in identifying the underlying cause of cough-related headache.

Does the head-tilted swallow technique reduce aspiration risk in individuals with pharyngeal dysphagia?
4 answers
The head-tilted swallow technique can be effective in reducing aspiration risk in individuals with pharyngeal dysphagia. Studies have shown that head rotation during swallowing can be beneficial for patients with unilateral cervical osteophytes, improving swallowing safety and efficacy. Additionally, the chin tuck against resistance (CTAR) approach has been found to reduce aspiration rates and increase oral intake in individuals with post-stroke swallowing disorders. Furthermore, adopting a head flexion posture during swallowing has shown to result in earlier laryngeal closure, shallower bolus position, and decreased aspiration, thus improving Penetration-Aspiration Scale (PAS) scores. Implementing protocols for dysphagia evaluation in head and neck cancer patients can also help reduce complications like aspiration pneumonia, emphasizing the importance of early detection and management. Lastly, utilizing intensity-modulated radiotherapy (IMRT) techniques can spare critical swallowing-related structures, reducing high-dose volumes and potentially improving dysphagia outcomes in head and neck cancer patients.
What are the benefits of honey for soothing throat?
5 answers
Honey offers several benefits for soothing the throat. Studies have shown that honey can effectively reduce the frequency of cough in children with acute cough. Additionally, gargling with a solution containing honeysuckle and semen oroxyli has been found to relieve both resting and swallowing throat pain after Uvulopalatopharyngoplasty (UPPP). Furthermore, honey has been compared to diphenhydramine in nocturnal pediatric coughs, demonstrating superior effectiveness in improving various aspects of coughs and sleep quality in children and their parents. The therapeutic properties of honey, such as its antioxidant, anti-inflammatory, antimicrobial, and anticancer activities, contribute to its effectiveness in soothing the throat and providing relief from discomfort.
How does the frequency and duration of standing affect the mother's comfort and overall well-being during pregnancy?
5 answers
The frequency and duration of standing during pregnancy can significantly impact the mother's comfort and well-being. Research indicates that pregnant women experience physiological changes when standing, such as an increase in functional residual capacity, minute volume, and oxygen consumption, along with cardiovascular alterations. Prolonged standing in late pregnancy may pose risks to the fetus, potentially leading to low birth weight, prematurity, and stillbirths due to an 'uterovascular syndrome'. Additionally, pregnancy-induced modifications in the musculoskeletal system suggest that adjustments in posture, like increased pelvic anteversion and lumbar lordosis, aim to reduce muscle activation and spinal load, potentially enhancing comfort. Implementing pregnancy exercises can also improve comfort levels, as observed in pregnant women who reported increased comfort, better rest, and reduced nighttime awakenings after engaging in such activities.
What are the benefits of menthol for soothing throat?
5 answers
Menthol offers several benefits for soothing the throat. It activates cold receptors like TRPM8, inducing a cooling sensation that can soothe the upper respiratory tract. Menthol, commonly found in cough syrups, can reduce dyspnea and nasal obstruction by stimulating nasal cold receptors, providing antitussive and anti-irritative effects. Additionally, menthol in throat-soothing syrups, along with ingredients like peppermint, glycyrrhiza uralensis, and salvia miltiorrhiza, can have a soothing effect on the throat due to their antitussive properties. However, it's important to note that menthol, especially in mentholated cigarettes, can also have controversial effects by potentially facilitating smoke inhalation and promoting nicotine addiction.
What is the mechanism of action of thermoregulatory action in the blockade of PGE2 synthesis in the brain?
5 answers
The mechanism of action of thermoregulatory response in blocking PGE2 synthesis in the brain involves the activation of adrenoreceptors and the inhibition of cyclooxygenase-2 (COX-2) by selective inhibitors like Meloxicam. Activation of α1 adrenoreceptors leads to a PGE2-independent hyperthermic response, while α2 adrenoreceptors initially induce hypothermia followed by a PGE2-dependent fever sustained by COX-2-derived PGE2. Prostaglandins injected into the brain can modulate body temperature by affecting heat production, vasomotor tone, and heat loss mechanisms. Additionally, PGE2 has been implicated in fever induction, with competitive inhibition of cortisol by PGE2 at glucocorticoid receptors identified as a fundamental mechanism for dysfunctional temperature dynamics, including fever.
