RESUMO
We present the case of a 70-year-old woman presenting with nausea, diarrhoea and a generalised rash. Initial blood tests revealed obstructive deranged liver function tests and low haemoglobin. A haemolysis screen revealed raised reticulocytes, low haptoglobin and a positive direct antiglobulin test. 6 days into her admission, she developed lower limb weakness and loss of sensation. MRI spine showed no significant findings. Cerebrospinal fluid showed raised white blood cell count and raised protein. Nerve conduction studies were normal. The clinical picture was in keeping with transverse myelitis. Autoimmune and viral screens were negative except for a single result which provided the unifying diagnosis: Epstein-Barr virus (EBV). She responded to high dose intravenous corticosteroids and her rehabilitation is ongoing. EBV should be considered even in the older population.

A 60-year-old woman presented with sudden-onset epigastric pain, vomiting and small volume rectal bleeding. She had a history of mechanical mitral valve replacement, for which she was on warfarin. Computed tomography (CT) angiography of the abdomen showed gallstones, a fluid-filled stomach and faecal loading. She subsequently deteriorated with worsening abdominal pain and haemodynamic instability. Non-contrast CT showed small bowel ischaemia and infarction. She rapidly deteriorated and a decision was made that surgery was likely to be futile. She died soon afterwards. On review of the initial CT angiography, an occlusion within the superior mesenteric artery (SMA) was visualised. The post mortem showed small bowel infarction due to embolic occlusion of the SMA secondary to bacterial endocarditis of the prosthetic mitral valve. This case should prompt awareness among clinicians that acute mesenteric ischaemia secondary to septic embolisation should be considered in patients with risk factors for infective endocarditis presenting with acute abdominal pain.

BACKGROUND: Medical thoracoscopy (MT) is a well-established diagnostic procedure in cases of unexplained exudative pleural effusions. Despite the advantages of MT, challenges remain since occasionally malignancies mimic pleural inflammation. OBJECTIVES: To assess the relationship between the macroscopic appearance of the pleura at MT, the histology of the pleural biopsy and the final diagnosis after follow up. METHODS: Data was prospectively collected on patients undergoing MT over 8 years, using a standardised electronic thoracoscopy report. We report the sensitivity, specificity, positive and negative predictive values (PPV, NPV) of the macroscopic changes, the sensitivity of computer tomographic (CT) appearances and final outcome. RESULTS: A total of 228 thoracoscopies and biopsy were performed, 70 reports described benign macroscopic changes; of these 15.7% had malignant histology. When the final outcome was taken into account, the sensitivity of macroscopic appearance at MT was 91.5%, specificity 76.0%, PPV 88.6% and the NPV 81.4%. Nodular changes were more likely to be associated with malignancy (Chi2 75.5, p < 0.05). The CT scans performed prior to thoracoscopy had a poor sensitivity for the diagnosis of malignant pleural effusion (50%) and a good specificity in the diagnosis of benign disease (90.5%). CONCLUSION: A standardised structured report allows reliable evaluation of the macroscopic findings at MT. The PPV of the macroscopic findings for malignancy is relatively high; however, in a significant minority of cases despite benign-looking macroscopic changes the final diagnosis was malignancy. Careful consideration must be given in cases with benign histology to either monitoring or further diagnostic tests based on clinical suspicion.

BACKGROUND: There is an emerging understanding that coronavirus disease 2019 (COVID-19) is associated with increased incidence of pneumomediastinum. We aimed to determine its incidence among patients hospitalised with COVID-19 in the United Kingdom and describe factors associated with outcome. METHODS: A structured survey of pneumomediastinum and its incidence was conducted from September 2020 to February 2021. United Kingdom-wide participation was solicited via respiratory research networks. Identified patients had SARS-CoV-2 infection and radiologically proven pneumomediastinum. The primary outcomes were to determine incidence of pneumomediastinum in COVID-19 and to investigate risk factors associated with patient mortality. RESULTS: 377 cases of pneumomediastinum in COVID-19 were identified from 58â484 inpatients with COVID-19 at 53 hospitals during the study period, giving an incidence of 0.64%. Overall 120-day mortality in COVID-19 pneumomediastinum was 195/377 (51.7%). Pneumomediastinum in COVID-19 was associated with high rates of mechanical ventilation. 172/377 patients (45.6%) were mechanically ventilated at the point of diagnosis. Mechanical ventilation was the most important predictor of mortality in COVID-19 pneumomediastinum at the time of diagnosis and thereafter (p<0.001) along with increasing age (p<0.01) and diabetes mellitus (p=0.08). Switching patients from continuous positive airways pressure support to oxygen or high flow nasal oxygen after the diagnosis of pneumomediastinum was not associated with difference in mortality. CONCLUSIONS: Pneumomediastinum appears to be a marker of severe COVID-19 pneumonitis. The majority of patients in whom pneumomediastinum was identified had not been mechanically ventilated at the point of diagnosis.

OBJECTIVES: Chronic obstructive pulmonary disease (COPD) exacerbation is one of the most common reasons for hospital admission. Patients with COPD with a long length of stay (LoS) occupy a disproportionately high fraction of hospital bed-days. The objective of this study was to identify associations of long LoS in patients admitted with COPD exacerbation. MATERIAL AND METHODS: From December 2012 until June 2013, 499 patients were admitted to Queens Hospital, Romford, UK, with COPD exacerbation. Mean LoS was 7 days, with a median of 5 days, and a 90th percentile of 14 days. In this retrospective observational cohort study, 64 patients with a short LoS were compared with 62 patients with a long LoS. RESULTS: Relative to the short LoS, patients with long LoS had significantly lower arterial blood pH, higher arterial PaCO2 and HCO3, higher white cell count, higher globulin and more frequent chest X-ray changes, lower albumin levels, and lower Barthel and Braden scores. They were less likely to have seen the hospital COPD specialist nurse, more likely to require escalation of social care on discharge, and more likely to die during admission. Nearly 66% of the long LoS patients remained in hospital beyond the time of being medically fit for discharge. Commonly cited reasons for delayed discharge were the wait for therapy and social services assessments and the wait for commencement of community social care. CONCLUSION: Meticulous targeting of features peculiar to long LoS patients has the potential to reduce future hospital bed-days for patients with COPD in our and other hospitals.
RESUMO
Bochdalek hernias occur as a result of a congenital defect in the diaphragm enabling abdominal viscera to enter the thoracic cavity restricting lung expansion and ventilation. Bochdalek hernias, in the majority of cases, present in neonates and very rarely in adults. To the best of our knowledge, there are only four published cases of Bochdalek hernia in the adult population causing respiratory failure. We present the case of an 87-year-old woman who had three admissions in the past 6 months with type II respiratory failure due to a Bochdalek hernia which we believe was congenital but had gradually increased in size over the years to cause progressive decompensation with acute exacerbations requiring non-invasive ventilation.

Nitrofurantoin is commonly used for the treatment and prophylaxis of recurrent urinary tract infections (UTIs). Although relatively rare, nitrofurantoin is one of the commonest causes of drug-induced pulmonary disease, which can be potentially serious and even fatal. Knowledge of such potential adverse effects is essential to enable early recognition and withdrawal of the drug. Patients on long-term nitrofurantoin should be reviewed and monitored regularly. Management involves early consideration of the condition, and prompt withdrawal of the drug. We report three cases of nitrofurantoin-induced lung disease in patients who were on long-term nitrofurantoin for UTI prophylaxis and present a brief review of the literature on this subject.

Pulmonary embolism (PE) is a common finding in patients with underlying malignancy and is the commonest cause of acute cor pulmonale. A 65-year-old woman with a background of non-small-cell lung cancer presented to the emergency department with nausea and vomiting after starting erlotinib; she was pyrexial and had raised C-reactive protein. Despite aggressive fluid resuscitation and antibiotics the patient remained tachycardic, hypotensive, profoundly hypoxic and had a persistent raised jugular venous pulse. Massive PE was therefore suspected. A bedside echocardiogram demonstrated a dilated right ventricle and evidence of pulmonary hypertension. A CT pulmonary angiogram excluded a PE but revealed progression of the right hilar tumour causing complete obstruction of the right upper and middle lobe pulmonary arteries. This case highlights an important differential diagnosis when assessing patients with an underlying intrathoracic tumour with findings suggestive of PE and the importance of obtaining further imaging before considering thrombolysis.

There is a substantial body of evidence supporting an association between asthma severity and fungal exposure and sensitization. Fungal allergens are a recognized risk factor for severe asthma. We describe the case of a 44-year-old asthmatic whose asthma control deteriorated after moving to a new flat with walls covered in mould. Allergic bronchopulmonary aspergillosis was excluded. Although sensitization to Candida was demonstrated by a positive Candida-specific radioallergosorbent test, the patient did not entirely satisfy the criteria for a diagnosis of allergic bronchopulmonary candidiasis. The patient's asthma control improved after engaging in a monthly washing regimen of the walls. This case further demonstrates the association between fungal sensitization and asthma severity. The term severe asthma with fungal sensitization has been recently coined to describe this phenomenon.

Ectopic pregnancy is still the most common cause of maternal deaths in the first trimester. Here we report a case of a 29-year-old pregnant woman who presented with a 2-week history of lower abdominal pain and vaginal bleeding. She was initially diagnosed as having had a complete miscarriage. On the second presentation the patient was diagnosed with a tubal ectopic pregnancy. The patient was managed surgically and recovered uneventfully. The case is discussed, and a review of the literature in relation to the use of ultrasonography in the diagnosis of ectopic pregnancy is presented.
