COVID-19 presents with a spectrum of severity, ranging from asymptomatic or mild symptoms to those with acute respiratory distress syndrome. Corticosteroids are widely used for their efficacy in reducing inflammatory responses. However, its use may be limited to patients with immunosuppression. An adjunct therapy for cytokine storm in COVID-19 is extracorporeal blood purification therapies using high adsorptive filters, such as oXiris, to remove cytokines. We share our experience in using continuous renal replacement therapy with oXiris haemofilter as a temporising measure to high-dose corticosteroids in managing cytokine storm in a deteriorating COVID-19 patient with concomitant bacterial infection.
A 50-year-old Indian woman presented with acute dysphasia, left upper limb numbness and thrombocytopenia 12 days after receiving the ChAdOx1 nCoV-19 vaccine (AstraZeneca/Vaxzevria). MRI of the brain was unremarkable. Microangiopathic haemolytic anaemia with thrombocytopenia was noted on her peripheral blood film. A diagnosis of thrombotic thrombocytopenic purpura (TTP) was confirmed through the findings of absent ADAMTS13 (a disintegrin and metalloproteinase with a thrombospondin type 1 motif, member 13) activity and markedly raised titre of ADAMTS13 autoantibodies. Prompt treatment with plasma exchange, adjunctive steroids and rituximab was commenced. A remission of TTP was achieved and she was discharged 3 weeks after admission. While other immune-mediated conditions have been documented after receipt of the vaccine, this report highlights the first case of immune-mediated TTP diagnosed after administration of the ChAdOx1 nCoV-19 vaccine.
We report a pair of siblings who developed multisystem inflammatory syndrome in children (MIS-C) in close temporal proximity after recent exposure to SARS-CoV-2. Both siblings presented with Kawasaki disease-like features and haemodynamic instability, with the onset of symptoms within 6 days of each other. Remarkably, one of the siblings was the elder of a pair of monozygotic twins. The younger monozygotic twin, however, did not develop MIS-C.
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.
Paediatric upper airway obstruction is an emergency that requires immediate intervention. Among the myriad factors that leads to upper airway obstruction in paediatric age group, bilateral vocal cord palsy is not commonly encountered in clinical practice. The underlying cause of bilateral vocal cord palsy requires thorough investigation prior to deciding on the appropriate intervention. Herein, we report a 4-month-old baby boy who presented with recurrent inspiratory stridor with bilateral vocal cord palsy secondary to Arnold Chiari II malformation. Immediate intervention to drain the hydrocephalous resulted in complete resolution of stridor without having to perform a tracheostomy. We highlight the importance of meticulous and thorough investigations especially in children, as emergent airway intervention such as tracheostomy may result in detrimental effect to speech, swallowing as well as quality of life.
Anterior thoracic or thoracolumbar spinal surgery by retropleural approach always carries a risk of pneumothorax as its consequence. Conventionally, the Aerospace Medicine Association and the British Thoracic Society recommend 2 weeks delay of air travel for a patient with resolved postoperative pneumothorax. They also label active pneumothorax as an absolute contraindication for commercial air travel. Such a delay always causes psychological and financial stress to patients and family who are far from home. Here, we report three patients with postoperative pneumothorax, who insisted on early air travel despite being informed of the possible consequences.
Foreign body (FB) in the external auditory canal is more common among the paediatric age group compared with adult patients and it may be deposited in various ways. An accidental animate aural FB is reported to be commonly encountered in adults whereas inanimate FBs are likely to be found among adult patients with learning disability. An elderly man presented with accidental penetration of rattan tree stem into his ear while gardening. Removal of a FB from the external auditory canal requires expertise as deep penetration of a FB into the middle and inner ear may lead grave complications, especially when overzealous removal is attempted by nonear, nose and throat (ENT) personnel. This case emphasises on the importance of awareness of meticulous removal of a FB under proper visualisation so as to avoid unnecessary complications. Additionally, we propose an algorithm for proper removal of aural FB in an acute care setting.
Spontaneous mesenteric bleeding is an exceptionally rare clinical condition and potentially lethal especially among elderly patients who are taking oral anticoagulant. We present a case of a 79-year-old woman who presented to the emergency department with atypical chest pain which was radiating to the back. She developed profound hypotension with a sudden drop of haemoglobin. Contrast-enhanced CT of the aorta showed active mesenteric bleeding with mesenteric haematoma. The early diagnosis relies solely on a high index of suspicion of occult bleeding in patients with unexplained hypotension with a sudden drop of haemoglobin. Troponin can be falsely positive in mesenteric bleeding. Close monitoring to detect any sign of deterioration and early imaging in diagnosing intra-abdominal bleeding can help to avoid delay in treatment which is essential to prevent mortality and morbidity.
Obstetric haemorrhage is the leading cause of maternal death worldwide (27.1%) and more than 66% of its deaths were classified as postpartum haemorrhage (PPH). The most common cause of PPH is uterine atony. Obstetrician should be skillful in managing obstetric emergencies; especially pertaining to PPH. Application of the B-Lynch suture on an atonic uterus is one of the surgical options in PPH patients who wish to conserve the uterus and it has a very high success rate.We present a primigravida patient who developed massive primary PPH followed by disseminated intravascular coagulation, which was successfully managed with B-Lynch suture and bilateral internal iliac artery ligation. We described in detail regarding the management of massive PPH and application of these surgical procedures on the atonic uterus with an attempt to preserve the uterus and future fertility in this young patient.
Sarcomas are a group of rare malignant tumours of the connective tissues. They can occur in almost any location, but more frequently in the extremities. The occurrence of sarcomas in the head and neck region is less than 1%. We are presenting a case report of a very large cranial sarcoma. Gross total tumour excision was done with pedicle skin graft and titanium mesh cranioplasty. The excised tumour weighed approximately 1.1 kg. Histopathological examination showed primitive intermediate-sized tumour cells arranged in sheets, nests and cords with focal palisading. Postoperative MRI done 2 weeks post surgery showed no evidence of residual tumour.
We report the case of a middle-aged woman with a history of bipolar disorder, in the absence of alcohol or substance misuse. The patient had been maintained on fluphenazine decanoate depot and now presented acutely with cognitive dysfunction and rigidity. Laboratory tests revealed elevated creatine kinase, acute kidney injury with metabolic acidosis and transaminitis, leading to a provisional diagnosis of neuroleptic malignant syndrome (NMS). Neuroleptics were withheld; dialysis was commenced; and blood biochemistry parameters improved in tandem. However, mental status changes persisted, and re-evaluation revealed multidirectional nystagmus with bilateral past-pointing. MRI confirmed the diagnosis of Wernicke's encephalopathy (WE). Prompt recovery followed treatment with high-dose intravenous thiamine. We discuss the co-occurrence of NMS and non-alcoholic WE-highlighting the need for a high index of suspicion for these relatively rare neuropsychiatric diagnoses which are often missed in those with atypical presentations.
Atrial septal defect (ASD) is the most common congenital heart disease observed in adult. Several ECG findings are considered sensitive for the diagnosis of ASD. We describe a 50 years old man who displayed Crochetage sign, incomplete right bundle branch block (IRBBB) and right ventricular strain pattern on ECG. Crochetage sign is highly specific for ASD and it correlates with shunt severity. The diagnostic specificity for ASD increases if the R waves have both Crochetage patterns and IRBBB. It is important not to confuse Crochetage signs with IRBBB abnormalities on ECG. Our patient was ultimately diagnosed with a large ASD measuring 3 cm with bidirectional shunt and concomitant pulmonary thrombosis. This illustrates that high suspicion of the ASD with the use of good-old ECG signs remains relevant in this modern era. This also reminds us that patients with Eisenmenger syndrome are at higher risk for pulmonary thrombosis.
Anaesthesia for patients with severe lung fibrosis post COVID-19 infection requires special consideration. This is due to its propensity to cause perioperative anaesthetic catastrophe and possibility of cross infection among healthcare workers if not properly managed. This interesting article elaborates in detail the anaesthetic and surgical challenges in a morbidly obese patient who had a severe COVID-19 infection presenting for an elective spine surgery.
Bilimbi fruit is widely eaten in Malaysia. Rarely reported is its potential to cause acute kidney injury (AKI) in patients with prior normal renal function. The possible dangers of its consumption are still relatively unknown among many. This case highlights the importance of taking a thorough dietary history in patients with AKI. We also hope to increase awareness among healthcare professionals on the nephrotoxic and neurotoxic effects of bilimbi fruits.
Metastatic cancer to the oesophagus is rare. Most cases are diagnosed at autopsy or surgery. The breast is the most common organ bearing a primary tumour. Metastatic oesophageal tumours are nearly always located in the submucosal layer with normal benign-looking mucosa, rendering tissue diagnosis difficult. In the absence of breast-related symptoms, the diagnosis of oesophageal metastasis from breast primary would be very challenging. We report a case of a 50 year-old woman, who was referred to our centre for a second opinion after she was offered an esophagectomy for a suspected oesophageal carcinoma. She presented solely with dysphagia and weight loss. Multiple investigations were performed to investigate her dysphagia which eventually led to the diagnosis of metastatic breast cancer with oesophageal involvement. She underwent excision of right breast invasive lobular carcinoma with axillary dissection. She completed her adjuvant chemoradiotherapy and currently on daily dose of tamoxifen, whereby her dysphagia has dramatically improved.
The hyoid bone fracture has traditionally been attributed to strangulation and hanging. Although rare, ensuing its vague presentation, hyoid bone fracture is oftentimes overlooked and missed, leading to delayed complications. Herein, we are reporting an overlooked hyoid bone fracture in a man who attempted suicide by strangulating himself, whereby Valsalva manoeuvre performed during bedside flexible nasopharyngolaryngoscopy revealed the fractured segment. As the patient was stable and asymptomatic, he was successfully managed conservatively. We would like to highlight the awareness of the Valsalva manoeuvre, which could elicit hyoid bone fracture as missing or overlooking the fracture may lead to devastating complications which may ensue, such as respiratory distress.
