Abstract
Conventional lung cancer treatments include surgery, chemotherapy and radiotherapy; however, these treatments are often poorly tolerated by patients. Cannabinoids have been studied for use as a primary cancer treatment. Cannabinoids, which are chemically similar to our own body's endocannabinoids, can interact with signalling pathways to control the fate of cells, including cancer cells. We present a patient who declined conventional lung cancer treatment. Without the knowledge of her clinicians, she chose to self-administer 'cannabidiol (CBD) oil' orally 2-3 times daily. Serial imaging shows that her cancer reduced in size progressively from 41 mm to 10 mm over a period of 2.5 years. Previous studies have failed to agree on the usefulness of cannabinoids as a cancer treatment. This case appears to demonstrate a possible benefit of 'CBD oil' intake that may have resulted in the observed tumour regression. The use of cannabinoids as a potential cancer treatment justifies further research.

Abstract
A 62-year-old man presents with breathlessness 6 months following right pneumonectomy for lung adenocarcinoma. Previous investigations had not yielded a diagnosis and his symptoms were progressing. The patient described worsened symptoms when stood up (platypnoea), with profound hypoxia until laid supine (orthodeoxia). Platypnoea-orthodeoxia syndrome due to a right-to-left interatrial shunt was diagnosed on contrast-enhanced transoesophageal echocardiography with the patient undergoing successful percutaneous patent foramen ovale closure. Patent foramen ovale is often asymptomatic with a population prevalence of around 20%-30%. Anatomical shifts postpneumonectomy can open, or worsen a previously closed interatrial communication leading to right-to-left shunting of blood. Platypnoea-orthodeoxia is under-recognised, impairing quality of life and patient outcome. Investigations can be falsely reassuring, or poorly sensitive for the causative pathology. Percutaneous closure is safe with high success rates and this case highlights the need for a high index of suspicion for shunts, particularly in postpneumonectomy patients.

Abstract
INTRODUCTION Hospital quality improvement and hospital performance are commonly evaluated using parameters such as average length of stay (LOS), patient safety measures and rates of hospital readmission. Thirty-day readmission (30-DR) rates are widely used as a quality indicator and a quantifiable metric for hospitals since patients are often readmitted for the exacerbation of conditions from index admission. The quality of patient education and postdischarge care can influence readmission rates. We report the 30-DR rates of patients with asthma using a national dataset for the year 2013. OBJECTIVES The aim of our study was to assess the 30- day readmission (30-DR) rate as well as, the causes and predictors of readmissions. STUDY DESIGNS/METHODS Using the Nationwide Readmission Database (NRD) (2013), we identified primary discharge diagnoses of asthma by using International Classification of Diseases, Ninth Revision, Clinical Modification code '493'. Categorical and continuous variables were assessed by a χ2 test and a Student's t-test, respectively. The independent predictors of unplanned 30-DR were detected by multivariate analysis. We used sampling weights, which are provided in the NRD, to generate the national estimates. RESULTS There were 130 490 (weighted N=311 173) inpatient asthma admissions during 2013. The overall 30-DR for asthma was 11.9%. The associated factors for 30-DR were age 45-84 years (40.32% vs 29.05%; p<0.001), enrolment in Medicare (49.33% vs 30.61% p<0.001), extended LOS (mean, 4.40±0.06 vs 3.25±0.04 days; p<0.001), higher mean cost (US$8593.91 vs US$6741.31; p<0.001) and higher disposition against medical advice (DAMA) (4.14% vs 1.51%; p<0.001). The factors that increased the chance of 30-DR were advanced age (≥45-64 vs ≤17 years; OR 4.61, 95% CI 4.04 to 5.27, p<0.0001), male sex (OR 1.19, 95% CI 1.13 to 1.26, p<0.0001), a higher Charlson Comorbidity Index (CCI) (OR 1.16, 95% CI 1.14 to 1.18, p<0.0001), DAMA (OR 2.32, 95% CI 2.08 to 2.59, p<0.0001), non-compliance with medication (OR 1.34, 95% CI 1.24 to 1.46, p<0.0001), post-traumatic stress disorder (OR 1.48, 95% CI 1.22 to 1.79, p<0.0001), alcohol use (OR 1.45, 95% CI 1.27 to 1.65, p<0.0001), gastro-oesophageal reflux disease (OR 1.20, 95% CI 1.14 to 1.27, p<0.0001), obstructive sleep apnoea (OR 1.11, 95% CI 1.03 to 1.18, p<0.0042) and hypertension (OR 1.11, 95% CI 1.06 to 1.17, p<0.0001). CONCLUSIONS We found that the overall 30-DR rate for asthma was 11.9% all-cause readmission. Major causes of 30-DR were asthma exacerbation (36.74%), chronic obstructive pulmonary disease (11.47%), respiratory failure (6.46%), non-specific pneumonia (6.19%), septicaemia (3.61%) and congestive heart failure (3.32%). One-fourth of the revisits occurred in the first week, while half of the revisits took place in the first 2 weeks. Education regarding illness and the importance of medicine compliance could play a significant role in preventing asthma-related readmission.

Abstract
We report a case of a 74-year-old male patient who was referred to the respiratory clinic with an incidental finding of a left sided pleural effusion. He was initially being treated by the general practitioner for chest infection with productive cough that had limited resolution after course of oral antibiotics. At the pleural clinic, 1.5 L of serosanguineous fluid was drained and sent for diagnostics. However, the diagnosis only reached as far as idiopathic exudative effusion with lymphocytes and plasma cells. He was then referred for video-assisted thoracoscopic surgery pleural biopsy and pleurodesis. It revealed black pleura with abundant IgG4 positive cells. He is followed up in respiratory clinic where further discussion and treatment has commenced.

Abstract
We present a case of colorectal cancer with temporomandibular joint dysfunction and discuss the management of the case. Type IIIb temporomandibular disorder involves anterior dislocation of the articular disk, trismus and difficult intubation. A 68-year-old woman was scheduled for colectomy. The day before surgery, the patient had temporomandibular pain. On examination, the mouth opening was 13 mm. We diagnosed type IIIb temporomandibular disorder. A simple splint was fabricated with gauze and she bit it. The mouth opening was 55 mm on the day of surgery. The pain disappeared, and intubation was uneventful. Temporomandibular disorders are generally treated by dentists. It is beneficial for general hospitals without a dentistry department to employ a dental anaesthesiologist to assist in potentially difficult intubations in patients with temporomandibular disorders.

Abstract
Croup (laryngotracheitis) is frequently encountered in the emergency department in a young child presenting with stridor. We describe a rare case of croup secondary to SARS-CoV-2 in an 18-month-old child who presented with stridor and respiratory distress and required urgent intubation. Subsequently, the child developed multisystem inflammatory syndrome in children (MIS-C). The child was monitored in paediatric intensive care unit. We would like to highlight that COVID-19 croup in children may be an indicator for MIS-C, and close monitoring is warranted as MIS-C is a life-threatening condition. Our limited experience suggests that COVID-19 croup especially if associated with MIS-C has an underlying more severe pathology and may require prolonged treatment in comparison with the typical croup or even COVID-19 croup. It is important to recognise this clinical entity during a time when most countries are in a third wave of COVID-19 pandemic.

Abstract
Primary pneumomediastinum is the presence of air in the interstitium of the mediastinum. The exact aetiology is unclear; nevertheless, it has been reported more frequently in patients with asthma and in individuals who use recreational drugs. It is commonly preceded by a sharp rise in intrathoracic pressure as in a Valsalva-like manoeuvre. We describe a rare case of severe pneumomediastinum with a small pneumothorax related to cannabis smoking and aggravated by vigorous sexual intercourse. The patient was successfully treated conservatively due to clinical and radiological stability and the absence of secondary cause.

Abstract
AIMS Palivizumab is a monoclonal antibody which can prevent infection with respiratory syncytial virus (RSV). Due to its high cost, it is recommended for high-risk infants only. We aimed to determine the proportion of infants eligible for palivizumab treatment in England who receive at least one dose. METHODS We used the Hospital Treatment Insights database, which contains hospital admission records linked to hospital pharmacy dispensing data for 43 out of 153 hospitals in England. Infants born between 2010 and 2016 were considered eligible for palivizumab if their medical records indicated chronic lung disease (CLD), congenital heart disease (CHD) or severe immunodeficiency (SCID), and they met additional criteria based on gestational age at birth and age at start of the RSV season (beginning of October). We calculated the proportion of infants who received at least one dose of palivizumab in their first RSV season, and modelled the odds of treatment according to multiple child characteristics using logistic regression models. RESULTS We identified 3712 eligible children, of whom 2479 (67%) had complete information on all risk factors. Palivizumab was prescribed to 832 of eligible children (34%). Being born at <30 weeks' gestation, aged <6 months at the start of RSV season, and having two or more of CLD, CHD or SCID were associated with higher odds of treatment. CONCLUSION In England, palivizumab is not prescribed to the majority of children who are eligible to receive it. Doctors managing these infants may be unfamiliar with the eligibility criteria or constrained by other considerations, such as cost.

Abstract
A 55-year-old man with mental retardation and calcaneal tendon thickening was referred for a suspected genetic disease. His serum cholestanol was elevated and genetic analysis of his blood cells for CYP27A1 revealed a homozygous missense mutation. We diagnosed him with cerebrotendinous xanthomatosis (CTX). Chest radiography revealed diffuse micronodular and reticular opacities. Histological findings obtained from the transbronchial lung biopsy revealed foamy macrophages and multinucleate giant cells with marked lipid crystal clefts. Although there are few reports of pulmonary lesions in CTX, we concluded from the radiological and histopathological findings that the pulmonary lesions were indeed caused by the CTX. The patient was treated with chenodeoxycholic acid. His neurological findings and calcaneal tendon thickening were unchanged; however, his serum cholestanol and radiological abnormalities of the chest decreased.

Abstract
Nilotinib is used as standard treatment in managing chronic myeloid leukaemia (CML). A 23-year-old man with CML and on nilotinib was admitted to the intensive care unit due to respiratory failure. Three years prior, he developed pleural effusion from dasatinib therapy thus, his CML regimen was changed to nilotinib. Although the pleural effusion had once improved, the chest imaging revealed left-dominant bilateral pleural effusion. Endotracheal intubation and left thoracic drainage were performed. Nilotinib treatment was discontinued, and approximately 60 hours later, nilotinib concentrations of 927 and 2092 ng/mL were determined in his blood and pleural effusion, respectively. Severe pleural effusion may be induced in patients administering nilotinib, and nilotinib concentrations in blood and pleural effusion can be elevated in patients with nilotinib-related pleural effusion. Cross-occurrence of pleural effusions needs to be monitored precisely, especially in patients who are switched to other tyrosine kinase inhibitors after dasatinib treatment.

Abstract
Globally, there are now over 160 million confirmed cases of COVID-19 and more than 3 million deaths. While the majority of infected individuals recover, a significant proportion continue to experience symptoms and complications after their acute illness. Patients with 'long COVID' experience a wide range of physical and mental/psychological symptoms. Pooled prevalence data showed the 10 most prevalent reported symptoms were fatigue, shortness of breath, muscle pain, joint pain, headache, cough, chest pain, altered smell, altered taste and diarrhoea. Other common symptoms were cognitive impairment, memory loss, anxiety and sleep disorders. Beyond symptoms and complications, people with long COVID often reported impaired quality of life, mental health and employment issues. These individuals may require multidisciplinary care involving the long-term monitoring of symptoms, to identify potential complications, physical rehabilitation, mental health and social services support. Resilient healthcare systems are needed to ensure efficient and effective responses to future health challenges.

Abstract
We present a case of black pleural fluid following thoracic trauma. The unusual dark colour most strikingly resembled soy sauce as independently commented upon by multiple treating physicians. The black colouration could not be fully accounted for by haemothorax or cholethorax, so other differential diagnoses were investigated, including Aspergillus niger infection and malignant melanoma. The cause, however, was thought to be due to staining of the fluid with carbon deposited in the pleural space from the non-volatilised impurities from smoking crack cocaine. A novel use of a point-of-care urine toxicology assay confirmed the presence of cocaine in the pleural fluid. Considering a broad range of differential diagnoses is needed to avoid missing important causes of unusual pleural effusions.

Abstract
Transcricothyroid membrane (CTM) injection of local anaesthesia is widely used during bronchoscopic procedures. It is an effective way of delivering topical anaesthesia, and has been shown to reduce patient discomfort, improve clinician satisfaction and reduce overall sedation requirements. Risks from this procedure are uncommon and usually minor. Localisation of the CTM is usually performed clinically by palpation of anatomical landmarks and can vary depending on clinician skillset and experience. Clinical identification may be less accurate compared with ultrasound guidance in identifying puncture site, however, ultrasound is not always readily available and seldom used for this purpose. This case describes a rare complication following attempted local anaesthetic infiltration into the cricothyroid space, after clinical identification of puncture site. An obstructive fluid-filled mass formed around the site of injection on the right vocal cord; resulting in airway compromise, abandonment of procedure and subsequent intubation.

Abstract
A 42-year-old woman with chronic obstructive pulmonary disease was referred to the respiratory team due to shortness of breath on exertion and significant deterioration in pulmonary function tests. Her symptoms were progressively getting worse. This prompted a referral to the specialist team where further investigations were undertaken including a high-resolution CT scan followed by lung biopsy, which eventually revealed a diagnosis of lymphangioleiomyomatosis (LAM). Successful referral to the National LAM Centre in Nottingham provided the key therapeutic approach required to manage this rare condition. Diagnosing this rare condition was due to the multidisciplinary team approach, which involved input from the general practitioner, radiologist and respiratory consultant. The patient has been making good progress with pharmacological management.

Abstract
Chronic cavitary pulmonary aspergillosis (CCPA) is a slow destructive type of chronic pulmonary aspergillosis, characterised by multiple pulmonary cavities that develop and expand over several months or years. Pleural involvement in the form of pneumothorax has been rarely reported in CCPA. We report such an unusual case of an immunocompromised male, with a history of chronic cough and fever, presenting with acute onset of shortness of breath. Chest imaging showed bilateral multiple cavitating nodules, ground glass opacities and dense right middle lobe consolidations and right-sided pneumothorax. Bronchoalveolar lavage (BAL) showed septate hyaline hyphae on KOH (potassium hydroxide) staining and fungal culture grew Aspergillus fumigatus BAL and serum galactomanan were positive and serum IgG for A. fumigatus was 58 MgA/L (0-40MgA/L) confirming the cause of spontaneous secondary pneumothorax in our patient as CCPA.

Abstract
Secondary adrenal insufficiency (AI) occurs as the result of any process that disrupts normal hypothalamic and/or anterior pituitary function and causes a decrease in the secretion of steroid hormones from the adrenal cortex. The most common cause of secondary AI is exogenous corticosteroid therapy administered at supraphysiologic dosages for ≥ 1 month. AI caused by oral corticosteroids (OCS) is not well-recognized or commonly diagnosed but is often associated with reduced well-being and can be life-threatening in the event of an adrenal crisis. Corticosteroid use is common in respiratory diseases, and asthma is a representative condition that illustrates the potential challenges and opportunities related to corticosteroid-sparing therapies. For individuals with severe asthma (approximately 5%-10% of all cases), reduction or elimination of maintenance OCS without loss of control can now be accomplished with biologic therapies targeting inflammatory mediators. However, the optimal strategy to ensure early identification and treatment of AI and safe OCS withdrawal in routine clinical practice remains to be defined. Many studies with biologics have involved short evaluation periods and small sample sizes; in addition, cautious approaches to OCS tapering in studies with a placebo arm, coupled with inconsistent monitoring for AI, have contributed to the lack of clarity. If the goal is to greatly reduce and, where possible, eliminate long-term OCS use in severe asthma through the increasing adoption of biologic treatments, there is an urgent need for clinical trials that address both the speed of OCS withdrawal and how to monitor for AI.

Abstract
Elexacaftor/tezacaftor/ivacaftor (ETI) is a cystic fibrosis (CF) transmembrane regulator (CFTR) modulator. It is known to be efficacious in stable patients with severe pneumopathy, but there are few data concerning its effectiveness during acute exacerbations. We here describe its use in a woman with CF and respiratory failure.

Abstract
This is a rare case of development of bi-lateral chylous pleural effusion (containing parenteral nutrition material) along with pneumomediastinum due to punctured left subclavian vein following insertion of a peripherally inserted central venous catheter (PICC) line. Parenteral nutrition is usually preferred for patients unable to tolerate enteral feeding. Due to hypertonicity of the total parenteral nutrition material, it is usually administered via internal jugular or subclavian vein which have a rapid blood flow; therefore, resulting in adequate mixing. Literature studies are yet to clearly explain the communications between two pleural cavities; therefore, development of bilateral pleural effusions in association with pneumomediastinum makes this case more intriguing. We present the journey of a 43-year-old woman who required insertion of bilateral chest drains, followed by sternotomy and repair of the left subclavian vein after she was found in hypoxic respiratory failure 2 days following insertion of PICC line into her left subclavian vein.

Abstract
Abnormal communications between the systemic and pulmonary venous systems are rare but can present as a opacity on chest radiograph. A solitary vessel communicating as a fistula directly between the systemic arterial circulation and the pulmonary venous system is not widely described. These may have significant implications in the long-term cardiovascular health of an individual acting as a left to right shunt. There is no clear consensus as to the management, but surgical management and endovascular embolisation have been successfully used. We present a case where a systemic arteriaopulmonary fistula originating from the abdominal aorta and connecting to the right inferior pulmonary vein manifested as an incidental finding on a chest radiograph and was further evaluated on cross-sectional imaging in a young patient. Chest radiographs are non-specific and it is important to be aware of the less frequent but important pathologies that can be picked up on plain chest radiographs, which inturn should warrant further investigation. This is presented in conjunction with a review of the available literature along with a discussion regarding the differential diagnosis and management applicable to the general clinician.

Abstract
We present the case of a 65-year-old woman who presented with progressive dysphagia and was diagnosed with achalasia. She subsequently developed bilateral chylous pleural effusions, with no cause identified despite extensive investigations (including computed tomography (CT) scans, gastroscopy and medical thoracoscopy (MT)) and review at a dedicated pleural multidisciplinary team meeting.Despite optimal supportive management she deteriorated and was admitted to the intensive care unit, where she passed away due to sepsis and respiratory failure 10 months after initial presentation. A postmortem returned a diagnosis of epithelioid mesothelioma, encasing the carina, distal oesophagus and coeliac axis.Mesothelioma only very rarely presents with either chylous effusions or achalasia. Additionally while MT normally conveys excellent sensitivity for pleural malignancy, it was insufficient here. This case highlights how an unusually located mesothelioma can produce an unusual clinical picture. It also suggests a role for early video-assisted thoracoscopy to aid diagnosis.

Abstract
Unilateral pleural effusions are uncommonly reported in patients with SARS-CoV-2 pneumonitis. Herein, we report a case of a 42-year-old woman who presented to hospital with worsening dyspnoea on a background of a 2-week history of typical SARS-CoV-2 symptoms. On admission to the emergency department, the patient was severely hypoxic and hypotensive. A chest radiograph demonstrated a large left-sided pleural effusion with associated contralateral mediastinal shift (tension hydrothorax) and typical SARS-CoV-2 changes within the right lung. She was treated with thoracocentesis in which 2 L of serosanguinous, lymphocyte-rich fluid was drained from the left lung pleura. Following incubation, the pleural aspirate sample tested positive for Mycobacterium tuberculosis. This case demonstrates the need to exclude non-SARS-CoV-2-related causes of pleural effusions, particularly when patients present in an atypical manner, that is, with tension hydrothorax. Given the non-specific symptomatology of SARS-CoV-2 pneumonitis, this case illustrates the importance of excluding other causes of respiratory distress.
