An ABC approach to cardiothoracic complications and sequelae of COVID-19: a tertiary centre experience.

The Coronavirus disease 2019 (COVID-19) pandemic, caused by severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), has caused unprecedented challenges to healthcare professionals (HCPs) worldwide. HCPs faced an unknown disease causing many complications, including now well-established acute respiratory distress syndrome (ARDS) and pulmonary artery thromboembolic disease, and some not so well known, for instance, tracheobronchomalacia, tracheal tear or dehiscence, granulation tissue formation and pulmonary hypertension. Many of these complications require highly specialist care warranting early recognition of complications and involvement of appropriately trained professionals. Here, we review the complications and sequelae encountered at our tertiary care centre with follow-up data and potential management strategies using the A (Airway), B (Breathing), C (Circulation) approach. This will not only familiarise HCPs with the different complications of COVID-19, but also arm them with a systematic approach to these complications.

Are We Following iRefer Guidelines From the Royal College of Radiology When Requesting Abdominal X-rays?

Background Abdominal radiography is one of the most routinely performed radiological investigations in hospitals. It is one of the initial investigations done in hospitals. Numerous studies have shown that abdominal X-rays have low sensitivity in several conditions such as acute abdominal pain. Methodology This study aims to first identify whether the Royal College of Radiology guidelines are being adhered to while requesting abdominal X-rays and, second, to identify the number of unnecessary requests made in the Betsi Cadwaladr health board. This is a retrospective audit of abdominal X-ray request data collected between the 1st and 23rd of August 2022. Data were collected from the electronic radiology record system. iRefer guidelines by the Royal College of Radiology were used as a reference to compare the requests made, and data were then analysed accordingly. Data are reported descriptively using percentages. Data analysis was done using SPSS version 20 (IBM Corp., Armonk, NY, USA). Results Of the total 242 abdominal X-rays noted, 89.67% of requests were according to the iRefer guidelines while 10.33% of requests were not. A total of 73.14% of cases were suspected to have an intestinal obstruction, and the positivity rate for the same was only 12.39%. Conclusions The majority of the requests followed the guidelines. However, there is an urgent need to develop local guidelines to reduce needless abdominal X-rays.

Medullary brain abscess secondary to dental procedure caused by Streptococcus intermedius.

Brainstem abscess is an uncommon occurrence in itself and an abscess in the medulla oblongata is even rarer. Although these abscesses have established association with head and neck infections, we report the first known case of medullary abscess that was found to be strongly associated with dental procedure. Important point to note is that a simple procedure like tooth extraction can predispose spread of infective seeding to distant sites. High clinical index of suspicion and early diagnosis are essential, as if left untreated, the brainstem abscess is almost always fatal otherwise.

Rare case of plasmablastic myeloma diagnosed on lung biopsy.

Plasmablastic myeloma is a rare variant of multiple myeloma characterised by neoplastic proliferation of single clone of plasma cells producing monoclonal immunoglobulins. A 60-year-old man presented to hospital with a 6-week history of chest pain, back pain, leg weakness and numbness. Imaging revealed a 75 mm left lobular lung mass with chest wall invasion, metastatic bony and soft-tissue deposits and spinal cord compression at T5 level. Lung biopsy, for suspected metastatic lung cancer, surprisingly showed features of plasmablastic myeloma. Protein electrophoresis demonstrated 2 g/L of IgG lambda paraproteinaemia and an increase in lambda light chains with reduced kappa/lambda ratio of 0.01. Bone marrow biopsy did not show evidence of infiltration by disease. The patient received radiotherapy to the spine; responded to third-line chemotherapy and received autologous stem cell transplant. This case adds to the rare causes of lung mass and is the first reported case of plasmablastic myeloma diagnosed on lung biopsy.
