BACKGROUND
Osimertinib, a third-generation tyrosine kinase inhibitor (TKI), has demonstrated significant efficacy in treating non-small cell lung cancer (NSCLC) patients with epidermal growth factor receptor (EGFR) mutations. However, EGFR-TKI-induced interstitial lung disease (ILD), a well-known adverse effect, can seriously affect the treatment outcome. There is currently no international consensus on the efficacy and safety of re-administration of EGFR-TKI after EGFR-TKI-induced ILD.
CASE SUMMARY
We report a case of a 62-year-old male with stage IV lung adenocarcinoma and EGFR L858R mutation who was treated with osimertinib at a dose of 80 mg/day as first-line therapy. On the sixth day of treatment, the patient developed grade 4 ILD, chest tightness, shortness of breath, and paroxysmal dry cough. Arterial blood gas analysis indicated the presence of type I respiratory failure, while the chest CT scan revealed newly developed ground-glass opacities in both lungs and a considerable amount of pleural effusion on the left side. Subsequently, the patient was administered methylprednisolone for anti-inflammatory therapy, in conjunction with oxygen therapy, anti-infection treatment, and closed thoracic drainage, which resulted in a favourable recovery and discharge after 18 days. During this period, the patient adhered to third-generation EGFR-TKI oral targeted therapy. Nevertheless, within a week of discharge, the patient was readmitted due to the recurrence of chest tightness and shortness of breath. A chest CT scan indicated a recurrent ILD. Despite the administration of high-dose methylprednisolone for 9 days, the patient's condition continued to deteriorate, ultimately resulting in death.
CONCLUSION
It is of the utmost importance to conduct a meticulous evaluation of the severity of osimertinib-induced ILD in order to ascertain the potential risks and benefits of EGFR-TKI rechallenge. Particularly, for patients with grade 4 ILD, firm drug discontinuation should be considered.

Ectopic goitre, presenting as an isolated thoracic mass without connection to the main thyroid gland enlargement, is a rare occurrence. We describe a case where a patient reported persistent dry cough and back pain for 1 year, along with throat discomfort unresponsive to medication. A 2×1 cm swelling was noted over the right anterior aspect of the neck. Extensive evaluation, including chest X-rays and contrast-enhanced CT of the thorax, revealed a mediastinal mass suggestive of an ectopic thyroid.This case presents a distinctive scenario involving the simultaneous presence of ectopic mediastinal and cervical thyroid lesions. Both were effectively managed using a minimally invasive approach, combining video-assisted thoracic surgery for the excision of the mediastinal mass and a bilateral axillo-breast approach for the cervical lesion in a single procedure. This approach yielded minimal morbidity, aesthetically pleasing outcomes and rapid recovery. Remarkably, such a case has not been previously documented in the available literature.

Successful Avoidance of Cicatricial Tracheobronchial Stenosis in a Patient With Endobronchial Tuberculosis by Early Administration of Systemic High-Dose Corticosteroids: A Case Report.
A 63-year-old Japanese woman was referred to our hospital due to dry cough, fever, hoarseness, stridor, and difficulty breathing. Chest computed tomography showed circumferential wall thickening in the trachea, carina, right main bronchus, and right upper lobe bronchus, and granular and nodular shadows in right S. Flexible laryngofiberscopy showed yellowish dry respiratory secretions adhering to the subglottis. Bronchoscopic findings showed that the tracheobronchial mucosa was swollen, hyperemic, and covered with yellowish-white, cheese-like materials, and ulcerative lesions with white coatings were observed from the subglottis to the trachea, carina, right main bronchus, and right upper lobe bronchus. A diagnosis of endobronchial tuberculosis (EBTB) was confirmed by polymerase chain reaction testing, and cultures were positive for . In addition to anti-tuberculosis chemotherapy, intravenous high-dose methylprednisolone reduced her severe respiratory symptoms and prevented cicatricial tracheobronchial stenosis. Early administration of systemic high-dose corticosteroids may be effective for EBTB patients with severely active tracheobronchial mucosal and submucosal lesions.

Rocky Mountain spotted fever, a potentially fatal tick-borne disease thought to be confined to specific climates and geographic locations, is expanding its reach due to climate change. This is demonstrated by a 73-year-old woman who contracted Rocky Mountain spotted fever outside endemic areas during travel in Canada. Presenting with fevers, arthralgia, weakness, non-bloody diarrhea, conjunctivitis, mild cough, and a rash, this patient was initially started on moxifloxacin (400 mg PO/day) for suspected pneumonia. Treatment was changed to doxycycline (100 mg PO twice daily for 7 days) after dermatology was consulted, and Rocky Mountain spotted fever was thought to be higher on the differential. Rocky Mountain spotted fever was confirmed, and the patient responded well to antibiotics, improving by discharge. The disease's expansion into previously thought nonendemic areas is thought to be linked to milder winters and more extreme dry summers, facilitating pathogen development and tick lineage expansion.

BACKGROUND Lung cancer is the most common malignant neoplasm diagnosed worldwide. Early diagnosis and treatment are of great importance for patient's prognosis. A wide variety of pulmonary conditions display clinical and radiological presentation similar to that of lung cancer, and the awareness of their existence can help in making correct diagnoses. CASE REPORT This article presents a description of 4 patients with an insidious type of lesions mimicking pulmonary carcinomas. The first patient was referred to Department with a tumor-like lesion in the right lung. After CT of the chest and core-needle biopsy, the lesion turned out to be an ectopic thyroid tissue. The second patient reported a dry cough and weight loss. A lung nodule mass was revealed in chest CT and the patient was diagnosed with pulmonary tuberculoma. The remaining 2 patients, despite the suspicion of lung cancer, were subsequently diagnosed with a post-traumatic pleural hematoma and diffuse large B cell lymphoma. CONCLUSIONS Low-dose computed tomography of the chest plays a significant role in the diagnosis of newly detected lesions in the lungs. However, due to the similarity of the image of cancer to that of other diseases, the ultimate diagnosis should be based on the interpretation of full imaging diagnostic tests, clinical presentation, and histopathological examination of the material obtained from the lesion. Analysis of cases enables us to expand our understanding of the diseases that need to be considered in differential diagnosis of a patient with a detected tumor-like lesion in the lungs.

A 27-year-old man with Allergic rhino sinusitis presented to our hospital in July 2020 with complaints of continuous sneezing, coughing while rising from bed for half an hour, and the same complaints repeated in the afternoon for half an hour, as well as a continuous dry cough for half an hour in the evening. He also had complaints of itching and skin rashes, particularly in his limbs. He underwent yoga (45 minutes, 5-6 days a week) including Jalaneti (a yogic cleansing technique, i.e. nasal irrigation with warm salt water for twice a week), hydrotherapy (enema using neem leaves paste mixed with water and steam bath on first day, followed by facial steam on alternate days) and Acupuncture (one session a week) for 8 months. Results showed a reduction in immunoglobulin E (IgE) levels and symptom severity suggesting that integrated yoga, hydrotherapy, and acupuncture are effective in the management of chronic allergic rhinosinusitis. All treatments were well tolerated without adverse effects. Though the result is encouraging, further studies are required with a larger sample size.

BACKGROUND
Small airway dysfunction (SAD) and airway inflammation are vital in asthma exacerbations. Type 2 inflammation (T2), mediated by cytokines from T helper 2 cell (Th2) such as interleukin (IL)-4, IL-5, and IL-13, is a potential mechanism underlying SAD. Research on small airway function in asthma is limited. We aimed to explore the correlation between small airway function and respiratory symptoms and comorbidity in T2 and non-T2 asthma.
METHODS
Derived from the National Health and Nutrition Examination Survey (NHANES), our study encompassed 2,420 asthma patients aged 6 - 79 years, including pulmonary function (PF) data such as forced expiratory flow between 25% and 75% of forced vital capacity (FEF), forced expiratory volume in 1 second (FEV), forced expiratory volume in 3 seconds (FEV), forced expiratory volume in 6 seconds (FEV), and forced vital capacity (FVC). To evaluate the small airway function, we calculated z-scores for FEF, FEF/FVC, FEV/FEV, and FEV/FEV. Logistic regression determined the adjusted odds ratios (aORs) for symptoms and comorbidity.
RESULTS
FEF, FEV/FEV, and FEV/FEV correlated with asthmatic symptoms. FEF had the strongest association with wheezing or whistling attacks. An increase of 1 standard deviations (SD) in FEF reduced recurrent wheezing (aOR: 0.70; 95% confidence intervals (95% CIs): 0.65 - 0.76) and severe attacks (aOR: 0.67; 95% CI: 0.62 - 0.94). These indices were also linked to dry cough and hay fever, particularly FEV/FEV reducing hay fever risk (aOR: 0.70; 95% CI: 0.55 - 0.91) in non-T2 asthma. FEF/FVC related to persistent (aOR: 0.78; 95% CI: 0.72 - 0.84) and severe attacks (aOR: 1.14; 95% CI: 1.08 - 1.22) in non-T2 groups. Lower indices combined with T2 exposure raised severe attack risk.
CONCLUSIONS
In this nationwide study, small airway function correlated with symptom onset, especially in T2 asthma. Small airway injury differed between T2 and non-T2 asthma. Prospective research is needed to establish reference values.

We report an autochthonous case of mild unifocal chronic pulmonary paracoccidioidomycosis in a 48-year-old previously healthy woman with no history of possible environmental exposures in endemic rural areas, supposedly resulting from reactivation of a latent pulmonary focus secondary to the use of methotrexate for the control of Chikungunya arthropathy. Laboratory investigation ruled out other immunosuppression. Her only symptoms were a dry cough and chest pain. Diagnosis confirmed by needle lung biopsy. There were no abnormalities on physical examination nor evidence of central nervous system involvement. MRI of the total abdomen showed no involvement of other organs. Computed chest tomography showed a favorable evolution under the use of itraconazole (200 mg/day). Different tomographic presentations findings are highlighted when performed before and after treatment. CONCLUSIONS: PCM should be considered even in a woman without a history of consistent environmental exposure and in a non-endemic geographic area.

BACKGROUND
Refractory chronic cough (RCC) patients typically complain of a dry cough. Sputum production in these patients has rarely been described in the literature. However, sputum production in RCC may be common, troublesome and particularly challenging to manage.
AIMS
We aimed to characterise patients referred to our regional specialist cough clinic who have significant sputum production (≥1 teaspoon of sputum daily) and compare their demographics, symptomatology and investigation results to those presenting with a dry RCC.
METHODS
A retrospective case note analysis of all consecutive referrals to a tertiary cough clinic identified as having a productive cough (≥1 teaspoon of sputum daily) was performed over a 12-month period. They were compared to a paired number of patients with dry RCC.
RESULTS
Patients with productive cough represented nearly a quarter (98/398, 24.6 %) of new patient referrals to the clinic. Demographic information, symptomatology and investigation results were comparable to those with a dry RCC. Over a third, 35.8 % of patients with a productive cough reported expectorating an egg-cupful of sputum or more a day. Nearly half, 40% of those with high volume sputum production (≥egg-cupful daily) had both a normal CT thorax and normal spirometry.
CONCLUSIONS
Patients with RCC can expectorate significant volumes of sputum in the absence of underlying lung disease. This group have similar demographics to those with dry RCC. This is the first piece of work to our knowledge to describe this cohort. Future work needs to acknowledge this forgotten phenotype to ensure that they receive comprehensive evaluation and evidenced based treatment.
