Melioidosis is a protean disease which is endemic to Southeast Asia and northern Australia. Here, we report a case of infected aortic aneurysm due to Burkholderia pseudomallei in an immunocompetent man 6 months after a trip to northern Malaysia. This patient initially received inappropriate surgical and antibiotic treatment, leading to a peri-prosthetic aortic infection with lumbar spondylitis and contiguous psoas muscle abscess. This case highlights the difficulty of diagnosing melioidosis given its diverse clinical manifestations and the limits of routine microbiological methods to identify B. pseudomallei Melioidosis should be considered a possible diagnosis in individuals with unexplained fever subsequent to travel in an endemic area.
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.
Anaesthesia for patients with huge mediastinal mass is very challenging due to the cardiorespiratory embarrassment that may occur. We present a patient with this condition, which was complicated by total airway obstruction, intraoperatively. We discuss the importance of patient positioning and the role of spontaneous ventilation.
Tularaemia is a rare infectious disease endemic in most European countries caused by the bacterium Francisella tularensis 1 Patients often show acute non-specific symptoms, which causes a delay in diagnosis and proper treatment, potentially resulting in significant morbidities such as deep neck abscess, meningitis, endocarditis and septic shock. The authors present a case of a 5-year old boy with a 4-day history of fever, sore throat and painful cervical lymphadenopathy, whose clinical progression worsened despite being treated with recommended antibiotics as per WHO guidelines once the diagnosis of Tularaemia was confirmed by serologic tests. He developed a parapharyngeal abscess and a persistent left necrotic cervical lymph node, which both were surgically drained and excised, respectively, and an extended course of antibiotic was given. Subsequently, the patient fully recovered from the illness and the follow-up was negative for relapse.
Ectopic adrenocorticotropic hormone (ACTH) syndrome (EAS) is rarely caused by a phaeochromocytoma. We report a case of a 51-year-old woman with an 8-year history of severe constipation who underwent extensive investigations including gastroscopy, colonoscopy, ultrasonography, colonic transit studies and isotope defeacography, which did not reveal any pathology other than slow colonic transit time. The unifying diagnosis of ectopic ACTH and phaeochromocytoma was made after the case was initially investigated for an adrenal incidentaloma. Multiple challenges had to be overcome prior to surgery for the functioning adrenal adenoma including management of refractory hypokalaemia, poor nutritional status, persistent hyperglycaemia, labile blood pressure and florid hypercortisolaemia driving the metabolic derangements. She underwent an uneventful left-sided adrenalectomy and required no medication thereafter with normal blood pressure, blood glucose and serum potassium and resolution of constipation and abdominal symptoms. In conclusion, patients with EAS related to phaeochromocytoma are rare and present with distinctive diagnostic and management challenges but if diagnosed successfully and managed intensively, they are curable.
We report a rare, potentially sight-threatening ocular complication due to central venous stenosis related to a previous site of haemodialysis catheter. A dialysis-dependent woman in her 60s presented with left eye redness for 1 month followed by a remarkably prominent vessel on the left upper eyelid for 2 weeks. Examinations found left eyelid oedema with prominent venous dilatation on the upper eyelid as well as left eye mild proptosis, conjunctiva injection with corkscrew vessels, raised intraocular pressure, and dilated and tortuous retina vessels. Central thoracic venogram showed total occlusion on the left brachiocephalic vein with retrograde reflux to the jugular vein. An endovascular percutaneous transluminal balloon angioplasty was performed for the left brachiocephalic vein stenosis, which resolved the orbital, facial and neck venous congestion. The patient remained asymptomatic after 1 year.
Hyperkalaemic periodic paralysis is a rare skeletal muscle disorder which is characterised by episodic muscle paralysis associated with hyperkalaemia. Although it is an autosomal-dominant disease, cases of de novo mutations have been reported. We report the case of a 30-year-old woman, gravida 5 para 3+1, who was planned for an elective repeated caesarean section at 38 weeks and 3 days of pregnancy. She developed recurrent episodes of hyperkalaemic periodic paralysis after receiving corticosteroids. Intravenous calcium gluconate was administered to normalise potassium levels (from 6.3 mmol/L to 4.1 mmol/L). Extra anaesthetic precautions were taken during the caesarean delivery. Postoperatively, she was well and discharged from the ward. She encountered similar symptoms in her third pregnancy, and there was no family history of muscle weakness which suggested a de novo mutation. Pregnancy seemed to result in vulnerability to hyperkalaemic attacks as she was never symptomatic outside pregnancy.
A man in his 20s with underlying chemorefractory primary T-lymphoblastic lymphoma and hypereosinophilia developed acute chest pain in the ward after readmission for disease progression. ECG showed widespread ST depression and serum troponin was markedly elevated. Transthoracic echocardiography showed diffused thrombus deposition with preserved ejection fraction consistent with eosinophilic myocarditis. The patient ultimately succumbed to the disease, after complications with severe hospital-acquired pneumonia.
We present a case of a 20-year-old woman presenting initially with an asymptomatic palatal swelling. Radiographic examination showed a cyst at the right maxilla with bucco-lingual expansion and perforation of palatal bone. Incisional biopsy was carried out via a buccal approach and the result revealed a benign odontogenic cyst, in keeping with radicular cyst. The patient was then scheduled for cyst enucleation. During the procedure, it was found that the palatal lesion was unrelated to the maxillary cyst. Incisional biopsy of the palatal mass was carried out and revealed a low-grade mucoepidermoid carcinoma. The patient then had a partial maxillectomy with fibula flap reconstruction. There was no recurrence at postoperative 1 year follow-up and she was rehabilitated with dental implants.
Pseudoaneurysm of the ankle involving the posterior tibial artery is a rare presentation with only four paediatric cases previously reported in English literature. We report a new case following blunt trauma with the clinical presentation and management strategy. A 6-year-old boy presented with a pulsatile swelling at the medial aspect of ankle following a history of blunt trauma 3 weeks ago. Imaging confirmed pseudoaneurysm involving the distal posterior tibial artery. Excision of the pseudoaneurysm was performed without any complication.
Ruptured renal angiomyolipoma in pregnancy is uncommon. Pregnant women may present with nonspecific symptoms such as flank or abdominal pain, contraction pain and haematuria. A thorough assessment is needed to reach the correct diagnosis. Management varies between conservative measures, radiological intervention or surgery depending on the patient's haemodynamic status and foetal condition. We present a case of a woman in her 30s, gravida 5 para 3+1 at 28 weeks of gestation, who presented with pain. The pain worsened, and she went into hypovolaemic shock. An exploratory laparotomy and emergency caesarean section were done. Retroperitoneal haematoma was found intraoperatively, but the source of bleeding was difficult to determine. An abdominal CT angiogram subsequently revealed an ongoing bleeding from a ruptured angiomyolipoma. An emergency nephrectomy was performed, and the bleeding was secured.
Paget's disease is a metabolic disorder of bone caused due to defect in the remodelling process and is very common in western countries but is very rare in Asians and Africans. It was first described by a British scientist Sir James Paget in 1877. It can be monostotic or polyostotic depending on the number of bones involved. It most commonly affects older people of more than 50 years. Disease involvement can be symptomatic or asymptomatic depending on the extent of the disease process. Diagnosis of Paget's disease can be made by raised serum alkaline phosphatase levels, radiological examination and by radioisotope bone scans.
Dens invaginatus (DI) and gemination are two developmental abnormalities that are well reported in the dental literature, but their coexistence in a single tooth is rare. Such situations worsen the risk factors associated with these anomalies, and the treatment plan should be customised as they possess altered morphology and anatomy. A 19-year-old girl came for evaluation of a cracked tooth in the front region of the upper jaw. The tooth showed clinical features of gemination and radiographic features of DI, and was diagnosed as DI in geminated maxillary lateral incisor. The differential diagnoses based on clinical appearance without radiographic investigation may warrant the treatment approach if these two abnormalities coexist in a single tooth. The report also highlights the importance of three-dimensional imaging in diagnosis and treatment planning of teeth with altered pulp canal anatomy. There are few reported cases in the literature detailing the treatment options for these two anomalies occurring in the same tooth.
Endobronchial hamartoma is a rare tumour. We report a 65-year-old woman with a history of recurrent pneumonia. Bronchoscopy revealed a 1 cm endobronchial mass obstructing the left upper lobe bronchus. Histopathological examination was consistent with a pulmonary hamartoma. This lesion was successfully debulked endoscopically with the use of a flexible cryoprobe without any complications. This case highlights both the importance of investigating recurrent pneumonia and the usefulness of endoscopic recanalisation in an obstructed segmental bronchus.
