Pneumocystis pneumonia causing cavitating lung nodules in an immunocompetent individual.Pneumocystis jirovecii pneumonia (PCP) is a potential life-threatening pulmonary infection which commonly manifests in immunosuppressed patients especially with HIV, with underlying malignancies, severe malnutrition as well as those on immunosuppressive treatments. There have been case reports of symptomatic PCP in individuals with a normally functioning immune system with typical clinical features and radiologic findings of bilateral and diffuse interstitial opacities. However, PCP in immunocompetent individuals presenting with lung nodules had been rarely reported. We report a 53-year-old immunocompetent gentleman who presented with subacute cough, progressive shortness of breath and radiographic findings of multiple lung nodules with central cavitation. The diagnosis of PCP was made by detection of PCP DNA PCR in bronchoalveolar lavage sample following fibreoptic bronchoscopy. This case also highlights the atypical radiographic findings of multiple cavitating lung nodules as a presentation of PCP in an immunocompetent patient.

Primary leptomeningeal lymphoma masquerading as infectious tubercular meningitis.Primary central nervous system lymphoma (PCNSL) is infrequent and often poses diagnostic conundrums due to its protean manifestations. We present the case of a South Asian young man presenting with raised intracranial pressure and a lymphocytic cerebrospinal fluid (CSF) with pronounced hypoglycorrhachia. Progression of the neuro-ophthalmic signs while on early stages of antitubercular treatment led to additional investigations that produced a final diagnosis of primary leptomeningeal lymphoma. Treatment with chemoimmunotherapy (methotrexate, cytarabine, thiotepa and rituximab (MATRix)) achieved full radiological remission followed by successful autologous transplant. This case highlights the difficulties and diagnostic dilemmas when PCNSL presents as a chronic meningeal infiltrative process. While contextually this CSF is most often indicative of central nervous system tuberculosis and justifies empirical treatment initiation alone, it is essential to include differential diagnoses in the investigation work-up, which also carry poor prognosis without timely treatment. High suspicion, multidisciplinary collaboration and appropriate CSF analysis were the key for a correct diagnosis.

Thoracic endometrial syndrome with unilateral exudative pleural effusionA woman in her 40s presented with exertional dyspnoea with an absence of haemoptysis, cough, fever and weight loss. The patient had a medical history of extensive endometriosis. Investigations revealed a large right-sided pleural effusion. The effusion was aspirated and was exudative in nature.A contrast-enhanced CT thorax was performed to help exclude dual pathology. The only positive finding was bilateral breast nodules, subsequently found to be benign fibroadenomas on histological analysis of biopsy samples.After malignancy was ruled out as a cause, the patient was referred for medical thoracoscopy for a biopsy and other investigations. Histology demonstrated the presence of endometrial tissue in the pleura and thereby confirmed the diagnosis of thoracic endometrial syndrome.Video-assisted thoracoscopic surgery repair of diaphragm and talc pleurodesis was carried out in an uncomplicated procedure and the patient was discharged with good recovery.

Childhood Pneumonia Diagnostics in Sub-Saharan Africa: A Systematic Review.Background: The prompt and accurate aetiological diagnosis of childhood pneumonia remains a challenge, especially in sub-Saharan Africa (SSA) because of limited resources for disease management. Objective: To review existing diagnostics for childhood pneumonia and potential modalities available to differentiate between bacterial and viral aetiologies in SSA. Methods: Online databases were searched for relevant articles published between January 2010 and December 2020 regarding childhood pneumonia diagnosis, conducted in SSA in children less than 18 years of age. The 2020 PRISMA checklist was utilized in appraising the selected studies and the QUADAS-2 tool was employed to assess the risk of bias in each of the studies selected. Results: A total of 1542 study titles and abstracts were screened following which 45 studies (39 on childhood pneumonia diagnostics and 6 on discriminating between bacterial and viral childhood pneumonia) were selected for review. Microbiological investigations (79.7%) constituted the most utilized index tests with blood-related specimen (32.8%) being the most utilized specimen. The most performed index diagnostic modality was polymerase chain reaction (PCR) (53.1%). The commonest reference gold standard technique was based on clinical diagnosis of the disease (46.2%). Only six studies in SSA attempted at using serum biomarkers, either singly or in combination to distinguish between aetiologies with use of combined biomarkers showing promise. Conclusion: Microbiological investigations are the most employed diagnostic methods for childhood pneumonia in SSA. More studies are required to evaluate the potential use of serum biomarkers; either singly or in combination with the goal of discriminating bacterial and viral childhood pneumonia.

BTS clinical statement for the diagnosis and management of ocular tuberculosis.The BTS clinical statement for the diagnosis and management of ocular tuberculosis (TB) draws on the expertise of both TB and and ophthalmic specialists to outline the current understanding of disease pathogenesis, diagnosis and management in adults. Published literature lacks high-quality evidence to inform clinical practice and there is also a paucity of data from animal models to elucidate mechanisms of disease. However, in order to improve and standardise patient care, this statement provides consensus points with the currently available data and agreed best practice.

Utility of severity assessment tools in COVID-19 pneumonia: a multicentre observational study.Background: Severity scores in pneumonia and sepsis are being applied to SARS-CoV-2 infection. We aimed to assess whether these severity scores are accurate predictors of early adverse outcomes in COVID-19. Methods: We conducted a multicentre observational study of hospitalised SARS-CoV-2 infection. We assessed risk scores (CURB65, qSOFA, Lac-CURB65, MuLBSTA and NEWS2) in relation to admission to intensive care or death within 7 days of admission, defined as early severe adverse events (ESAE). The 4C Mortality Score was also assessed in a sub-cohort of patients. Findings: In 2,387 participants, the overall mortality was 18%. In all scores examined, increasing score was associated with increased risk of ESAE. Area under the curve (AUC) to predict ESAE for CURB65, qSOFA, Lac-CURB65, MuLBSTA and NEWS2 were 0.61, 0.62, 0.59, 0.59 and 0.68, respectively. AUC to predict ESAE was 0.60 with ISARIC 4C Mortality Score. Conclusion: None of the scores examined accurately predicted ESAE in SARS-CoV-2 infection. Non-validated scores should not be used to inform clinical decision making in COVID-19. Keywords: COVID-19; collaborative; pneumonia; severity score.

Disseminated tuberculosis associated with deficient interleukin-23/tyrosine kinase 2 signalling.Tuberculosis (TB) remains a significant cause of morbidity and mortality globally. The disseminated form of the disease has a worse prognosis and is commonly associated with primary and acquired immunodeficiency states such as HIV/AIDS, post-organ transplant and malnutrition. However, disseminated TB in the context of isolated impaired cellular responses to interleukin (IL)-23 due to tyrosine kinase 2 (TYK2) deficiency has been rarely reported. We highlight the case of a young woman with pulmonary and central nervous system TB associated with previously undiagnosed IL-23/TYK2 signalling defects causing impaired response to IL-23. A significant clinical improvement was observed after introduction of adjunctive interferon-gamma therapy to her anti-tuberculous medications. This case emphasises the need to broadly evaluate for potential immune deficiencies in poorly responding patients with fully sensitive TB as well as the potential benefits of interferon-gamma therapy in patients with certain immune defects.

De novo pancytopaenia in an older adult with severe COVID-19 infectionDuring the COVID-19 pandemic, it was recognised that SARS-CoV-2 can cause multisystem illness. Non-respiratory complications observed early in the pandemic were haematological in nature. A rare but serious haematological complication of COVID-19 infection is pancytopaenia. We describe a case of an older adult without pre-existing haematological disease or risk factors for cell dyscrasia with severe pancytopaenia induced by COVID-19, who developed critical illness requiring respiratory support in intensive care and died. Our case report highlights that de novo pancytopaenia may only present with mild dermatological manifestations and may indicate severe COVID-19 infection. Management is primarily supportive and early involvement of haematology should be sought.

Respiratory Virtual Clinic: Quality Improvement ProjectPURPOSE: Virtual Clinic (VC) is a norm since the COVID-19 and there have been rapid developements to switch hospital services virtually. Our quality improvement project (QIP) predates COVID-19 hence the main aim of QIP was to establish a modern way of following up investigation after discharge and avoid non-clinical hospital or general pracitioner (GP) contact. METHODS: We screened the discharges from the respiratory ward. We reviewed the discharge summaries for February 2019 to look at the numbers that required any investigation post-discharge that could have been followed up virtually. We identified several patients and proceeded to set up a VC to be run by the respiratory trainees. VC referral form with strict citeria was configured and we did several teachings of the medical/nursing staff on the respiratory ward. We ran the pilot VC for March-April 2019. RESULTS: In our preliminary assessment, we had 19 investigations in February 2019 which were suitable for VC follow up. We received 45 VC referrals for for follow up in March/April 2019. These referrals were related to 28 individuals who would have otherwise required face to face clinic or GP follow up. CONCLUSIONS: Due to promising results, VC is now established as a formal clinic in our Trust and has taken a significant role of following up elegible COVID-19 and non-COVID-19 patients. CLINICAL IMPLICATIONS: The project exhibits evolutiornary methods to safely follow up patients whom otherwise would have required a specialist or GP clinic appointment. An established VC at the advent of COVID-19 gave us a head start over many other hospitals when establishing our services virtually.

Respiratory Function in Friedreich's Ataxia.Background: Friedreich's ataxia is an inherited, rare, progressive disorder of children and young adults. It is characterized by ataxia, loss of gait, scoliosis, cardiomyopathy, dysarthria and dysphagia, with reduced life expectancy. Alterations of respiratory dynamics and parameters are frequently observed. However, in the literature there are few, dated studies with small cohorts. Our study aims to make an objective analysis of the respiratory condition of both early and late stage FRDA patients, looking for correlations with the motor, skeletal, speech and genetic aspects of this condition. Materials and methods: This retrospective observational study is based on the collection of clinical and instrumental respiratory data of 44 subjects between 13 and 51 years attending a tertiary rehabilitation centre in northern Italy. The analysis was carried out using Pearson's correlation test, ANOVA test and post hoc tests. Results: Data show the presence of a recurrent pattern of respiratory dysfunction of a restrictive type, with reduction in forced vital capacity and of flow and pressure parameters. The severity of the respiratory condition correlates with the disease severity (measured with disease-specific scales), with pneumophonic alterations and with the severity of the thoracic scoliotic curve. Conclusions: Respiratory function is impaired at various degrees in FRDA. The complex condition of inco-ordination and hyposthenia in FRDA affects daytime and night-time respiratory efficiency. We believe that the respiratory deficit and the inefficiency of cough are indeed a clinical problem deserving consideration, especially in the context of the concomitant postural difficulty and the possible presence of dysphagia. Therefore, the rehabilitation project for the subject with FRDA should also consider the respiratory function.
