Background Nosocomial outbreaks of COVID-19 have been reported sporadically since the beginning of the COVID-19 pandemic. We sought to study the transmission dynamics in a nosocomial COVID-19 outbreak in our centre.

Methods This was a retrospective cohort study in a 500 bedded tertiary care hospital in South India. Inpatients who were suspected to have likely or definite hospital-acquired COVID-19 and hospital staff members who were found to be COVID-19 positive during the same time frame were studied and the likely transmission dynamics described.

Results During the study period, 173 patients were diagnosed to have COVID-19, out of which, 15 (8.6%) patients who fulfilled the criteria for likely or definitely hospital-acquired COVID-19 infection were identified from six different wards. During the same period, 121 hospital staff members were diagnosed with COVID-19. Out of these, 18 (14.9%) hospital staff members were identified who could have been the potential source of infection for these 15 patients based on the overlap of location of the staff and the patients, and their infectivity windows. Direct contact and fomite transmission were likely the predominant driver of transmission in our study as there was use of universal face masks and face shields.

Conclusion Despite the admission of a large number of COVID-19 patients and a relatively large proportion of hospital staff members who tested positive for the disease, the proportion of nosocomial COVID-19 in our centre remained low. A policy of universal gloving, coupled with the already existing practice of universal N95 masking and face shield use, could potentially bring down the rate of nosocomial COVID-19 even further.

Background Studies to evaluate long COVID symptoms and their risk factors are limited. We evaluated the presence of long COVID and its risk factors in patients discharged from a hospital with COVID-19 illness.

Methods This observational study included 271 COVID-19 patients admitted between February and July 2020 in a hospital in the UK. The primary outcome measure was to assess the duration and severity of long COVID and its predictors at 3, 6 and 9 months. Logistic regression was performed to assess the potential risk factors for long COVID.

Results Out of 89 patients interviewed, 55 (62%) had long COVID for 3 months, 46 (52%) for 6 months and 37 of the 75 patients admitted to the hospital with acute COVID-19 had long COVID for 9 months (49%). The most common long COVID symptoms were fatigue and breathlessness.

Conclusion Nearly two-thirds of patients at 3 months and a half at 9 months had long COVID. COVID-19 pneumonia was the strongest predictor of long COVID in Caucasians at 3 months.

Background The diagnosis of intestinal TB (ITB) is challenging because of its overlapping features with Crohn's disease. This outcome-based study evaluated the combination of colonoscopy, histopathology, Xpert MTB/RIF and TB culture for best sensitivity and specificity.

Method This was a four-year retrospective, observational study of 426 clinically suspected patients who underwent colonoscopy with biopsies for histopathology, Xpert MTB/RIF and TB culture. ITB was diagnosed using the composite reference standard (CRS), which comprised either histological features or culture or Xpert MTB/RIF positivity, and positive response to anti-tuberculous treatment on follow up.

Results 35 (8.2%) patients were diagnosed with ITB. Histopathology had the highest sensitivity (91.4%) and negative predictive value (99.2%), MTB/RIF had the highest specificity (100%) and positive predictive value (100%). A combinatorial approach with Xpert MTB/RIF and histopathology had optimal diagnostic value (97%), approaching 100% sensitivity with culture. 40% of cases were diagnosed within 12 hours with Xpert MTB/RIF and 97% cases within three days.

Conclusion This combinatorial diagnostic model provides rapid and reliable diagnosis of ITB which may be useful in endemic areas.

Background Mucormycosis has been reported in several Indian states with the second wave of COVID-19 from January 2021 onwards. This prospective study was conducted with the objective of defining the contribution or association of various known and many suspected factors in the incidence of this disease during the ongoing pandemic.

Method The study included 464 adults with mucormycosis. Basic demographic data were collected. Patient history of COVID infection, its severity, duration of treatment, and oxygen use was taken to assess the association. History of use of antibiotics, steroids, antivirals, biologicals, and other complementary treatments was sought. History of diabetes and other comorbidities was noted. Patients were investigated for mucor confirmation using a nasal swab KOH mount, nasal endoscopy with biopsy, and radiological investigations were done to assess the extent.

Results Out of 464 patients, 175 were known diabetics, and 157 were treated with steroids during COVID infection. Out of 287 post-COVID patients, 125 (44%) had rhino-mucormycosis (RM), 102 (35%) had rhino-oculo-mucormycosis (ROM) and 60 (21%) had rhino-oculo-cerebral-mucormycosis (ROCM). 162 did not have a history of COVID, of which 93 (57%) had RM, 48 (30%) had ROM and 21 (13%) had ROCM.

Conclusion This study has showed that COVID was not the only factor contributing to mucor, rather other factors such as diabetes, steroid use etc. were also contributory. Many patients who were suffering from mucormycosis did not have a history of COVID. Advanced age, ROCM, and ICU admission were associated with increased mortality.

We report a case of a 72-year-old woman who underwent transthoracic discectomy for a giant disc herniation at T9-T10 level causing significant cord compromise. Following removal of her non-suction chest drain, she was transferred to the acute spinal-orthogeriatric unit where she was under regular review by elderly care physicians as part of their spinal liaison role. Approximately four weeks after the operation, she started becoming dyspnoeic and her chest X-ray showed moderate left-sided pleural effusion which tested positive for (32-transferrin, a sensitive marker of cerebrospinal fluid, supporting a diagnosis of subarachnoid-pleural fistula. This is a very unusual cause of breathlessness in a postoperative patient.

A 39-year-old female presented with a one-week history of jaundice and nausea after taking an over-the-counter herbal supplement containing ashwagandha root extract. Initial investigations revealed a hepatocellular pattern of liver enzyme abnormality with jaundice. Investigations, including viral serology, liver specific autoantibodies and an ultrasound scan of the abdomen, were unremarkable. Liver biopsy showed an acute cholestatic hepatitis with confluent necrosis but no features of chronicity. These histopathological findings differ to that of a previously reported case. Review of recent literature revealed that some clinical features and the time course of liver injury were similar to previous reports of ashwagandha drug-induced liver injury (DILI). The patient received treatment with ursodeoxycholic acid. We compare this case to previous reported cases of ashwagandha DILI and discuss the biochemical and histopathological features of ashwagandha DILI, therapeutic strategies and the importance of recognising herbal supplements as a possible cause of DILI.

We describe two cases of giant cell arteritis where involvement of the superficial temporal artery and maxillary artery were demonstrated using colour doppler ultrasonography. Maxillary artery involvement is responsible for the symptoms of jaw claudication and toothache, and even headaches might be due to the involvement of the middle meningeal artery which is a branch of the maxillary artery. The maxillary artery has been difficult to visualise until now. There are international consensus definitions of ultrasonographic abnormalities seen in the superficial temporal artery affected by giant cell arteritis. We have used those definitions to demonstrate hypoechoic changes in the maxillary artery affected by giant cell arteritis. The maxillary artery can be visualised in the infratemporal fossa from an echo window between the condylar and coronoid processes of the mandible. This is the first proof of concept evidence that maxillary arteries can be visualised using bedside ultrasonography in giant cell arteritis.

Infectious and autoimmune diseases are distinct entities that require opposite therapeutic approaches. However, differentiating between the two can be a challenge, especially when the histopathology misguides the clinician. We highlight the case of a 66-year-old female who presented with fever, shortness of breath and cough for three months duration. She had raised inflammatory markers, and imaging revealed bilateral cavitating nodules. Histopathology revealed necrotising granulomatous inflammation along with acid-fast bacilli on Ziehl-Neelsen staining. The patient was diagnosed with tuberculosis and started on anti-tubercular therapy. When no response was seen, a rheumatologist was consulted, and a suspected diagnosis of granulomatosis with polyangiitis was made on the basis of clinical and laboratory features. Dramatic response to steroids and a negative mycobacteria culture confirmed the diagnosis. The patient responded to a combination of steroids and cyclophosphamide. This case highlights the importance of recognising the possibility of a false-positive acid-fast bacilli report.

Paraneoplastic glomerular disease is well recognised, although it most frequently presents with clinical features of the nephrotic syndrome. This case describes a 74-year-old male with metastatic rectal adenocarcinoma treated surgically with anterior resection followed by adjuvant capecitabine chemotherapy. Having previously had normal renal function, he developed an acute kidney injury with active urinary sediment following the discovery of liver metastases. A renal biopsy was performed, which revealed an active crescentic pauci-immune glomerulonephritis. The patient was treated with high dose oral corticosteroids which led to some improvement in renal function, although he was still left with significant kidney impairment, which limited further safe oncological treatment. This case highlights a rare presentation of glomerular disease in the setting of malignancy and also demonstrates the adverse impact that kidney impairment can have on outcomes in patients with cancer.

Cerebral salt wasting (CSW) is an important cause of hyponatraemia in the background of a central nervous system disease. It causes hypovolaemic hyponatraemia and is associated with polyuria and high urine sodium levels. It is important to distinguish it from the more common syndrome of inappropriate antidiuretic hormone and this is primarily based on the volume status. Although CSW has been known to present with confusion, stupor, abnormal behaviour and seizures, its association with catatonia is yet to be reported. We report a case in which the patient developed CSW and hyponatraemia as a sequela of tuberculous meningitis and presented with catatonia. Prompt correction of hyponatraemia resulted in complete reversal of catatonia. This highlights the importance of evaluating all patients with catatonia for electrolyte abnormalities, especially hyponatraemia as its correction leads to excellent outcomes.

Stylocarotid syndrome is a variant of Eagle's syndrome that depicts elongation of styloid process or calcification of stylohyoid ligament causing compression of external or internal carotid arteries. Because of this compression, several neurological presentations could occur ranging from transient ischaemic attacks to carotid dissection and devastating ischaemic stroke. It is a rare cause of stroke that many physicians are not familiar with, yet it can be readily diagnosed by computed tomography angiography (CTA). Styloidectomy remains the definitive treatment for stylocarotid syndrome, however conservative treatment can be attempted in certain patients.

Pulmonary hypertension is a rare and complex disease that arises from a wide range of underlying conditions. Therapeutic options have expanded enormously over the last two decades resulting in major improvements in prognosis for some patients. As a consequence, it is vital that the disease is recognised early and referred on to specialist centres for further investigation and definitive diagnosis to improve prognosis in this life-altering condition. Unfortunately, it remains the case in the UK that there is a delay in the diagnosis of pulmonary hypertension, often months or years after the onset of symptoms. This review aims to highlight key points in initial management and referral of patients with suspected pulmonary hypertension and presents three cases to underline these areas..

Several professional medical learned societies and organisations have recommended guidelines for management of various chronic diseases geared to achieve optimal control over the diseases and improve the quality of care. However, the data from around the world suggest that a majority of patients are not achieving those treatment targets. This has been well documented in diseases such as diabetes, hypertension, dyslipidaemia and rheumatoid arthritis, and clinical inertia is thought to be a major factor responsible. In this article, we have discussed clinical inertia in rheumatology practice, which has relevance to several other chronic non-communicable diseases as well.

The COVID-19 pandemic highlighted major challenges in governance and inequalities particularly among those from Black, Asian and minority ethnic (BAME) groups. This paper focuses on the BAME community and explores this through a governance lens, with particular reference to the representation and functioning of boards involved in healthcare and building a transparent culture. To illustrate this, the paper utilises a series of structured reflective questions with model answers termed Right Question, Right Answer and links to the Centre for Quality in Governance (CQG) Maturity Matrix. This article highlights the need to improve diversity and accountability of health and care organisations to their staff and local population. For governance to be effective, it must be aligned and comply with healthcare system regulations to ensure improvement of legislative acts and standards. The paper aims to inform government policy by moving from rhetoric, or merely describing challenges, to action and change by increasing accountability.

This is the second of two papers which examine a series of portraits of patients at the Royal Edinburgh Asylum (REA) which were undertaken in the 1880s by John Miles, who, as well as being a professional painter, was also an inmate of the Morningside institution. Alongside the portraits by Miles, we began, in Paper 1, to discuss a second series of portraits of the same patients, contained in a collection, entitled Bruised Reeds. In this paper we focus on the remaining portraits in this collection, before discussing the wider implications of the two series of portraits. These two series are of interest for several reasons. They are an example of patient art, only a small portion of which has survived from nineteenth century asylums. They are also in the tradition of patient portraiture. The patients in the portraits have been identified and their case notes examined. This information complements the portraits and helps to build a fuller picture of individual patients and their life in the Morningside Asylum. The case notes also reveal the symptomatology and behaviour of the patients. We discuss if the Bruised Reeds portraits were also by Miles, and suggest they were not.
