We report a successful case where a newborn with transfusion-related acute lung injury following an exchange transfusion was effectively treated using conservative methods, eliminating the need for surfactant therapy. Very few instances of this complication have been documented globally. A low birth weight, small for gestational age, term neonate, diagnosed with hyperbilirubinaemia due to Rh incompatibility, experienced sudden respiratory distress in the form of severe retractions, tachypnoea and cyanosis 3 hours after the procedure...

We describe an early adolescent male who was diagnosed with vascular malformation associated with unilateral limb overgrowth based on the clinical findings of a persistent port-wine stain since birth and gradually progressing right lower limb oedema since early childhood. Clinicians should keep in mind to clinically evaluate such malformations in detail, as well as contemplate genetic testing in patients presenting with a large port-wine stain at birth, particularly if well demarcated and lateral in a lower extremity...

Bartter syndrome is a genetic disorder characterised by chloride-unresponsive metabolic alkalosis, hypokalaemia, hypomagnesaemia and hypercalciuria. While it commonly presents antenatally or in early infancy, sometimes, drugs can induce a state similar to Bartter syndrome in any age group, called acquired Bartter syndrome. Polymyxins and aminoglycosides are the most commonly implicated drugs. Polymyxin B and polymyxin E (popularly known as colistin) are the two chemically similar polymyxins that are commonly used clinically...

A case of neonatal sepsis caused by Edwardsiella tarda , an uncommon pathogen typically associated with aquatic lifeforms, is described. The infant presented in septic shock with seizures and respiratory failure and was found to have meningitis, ventriculitis and a brain abscess requiring drainage. Only a small number of case reports of neonatal E. tarda infection, several with sepsis with poor auditory or neurodevelopmental outcomes or meningitis, have been described in the literature. This case report suggests that E...

A girl in middle childhood was referred to the paediatric surgical team with acute colicky abdominal pain and bile-stained vomiting. This was preceded by a viral illness. Investigations revealed raised inflammatory markers, and imaging of the abdomen demonstrated ileal and jejunal thickening. Concerns were raised regarding whether she had inflammatory bowel disease. Endoscopy revealed gastritis and duodenitis, and colonoscopy was unremarkable. Video capsule endoscopy demonstrated ulcers in the jejunum and ileum...

Acute eosinophilic pneumonia (AEP) is a rare cause of acute respiratory failure. Clinical presentations can range from dyspnoea, fever and cough, to rapidly progressive and potentially fulminant respiratory failure. While its exact cause is often unknown, associations with inhalational injuries and exposures to new medications have been described.We report a case of a middle-aged, non-smoking man with a history of alcohol use disorder. He presented with 4 days of shortness of breath that started hours after taking injectable naltrexone (Vivitrol)...

Subacute sclerosing panencephalitis (SSPE) is a fatal disorder that occurs as a rare complication of childhood measles. Symptoms typically manifest between the ages of 5 and 15. While the incidence of SSPE is declining globally, it is still prevalent in regions where measles remains common and vaccination rates are low due to poverty and lack of health education. Diagnosing SSPE can be challenging, particularly when patients exhibit unusual symptoms. A thorough clinical evaluation, including vaccination history, physical examination, electroencephalogram (EEG) and Cerebrospinal fluid (CSF) analysis, can help in making a diagnosis...

Tumour-induced osteomalacia is caused by tumorous production of fibroblast growth factor 23 (FGF23) leading to urinary phosphate wasting, hypophosphataemia and decreased vitamin D activation. The resulting osteomalacia presents with muscle weakness and bone pain but progresses to multiple pathological fractures. Patients often remain undiagnosed for years with severe physical, psychological and economic ramifications. A young woman presented with multiple spontaneous fractures including bilateral femoral fractures...

A man in his late 50s presented with severe dysphagia caused by a complex refractory benign stenosis that was completely obstructing the middle oesophagus. The patient was unsatisfied with the gastrostomy tube placed via laparotomy as a long-term solution. Therefore, we performed robot-assisted minimally invasive oesophagectomy (video). Mobilisation of the stomach and gastric conduit preparation were more difficult due to the previously inserted gastrostomy tube; thus, the conduit blood supply was assessed using indocyanine green fluorescence...

Neurofibromatosis type 1 (NF1) is an autosomal dominant disease with complete penetrance, most commonly known to affect the skin and eyes. Although lung involvement in the form of cysts and bullae occurs in up to 20% of adults, the seemingly intuitive association of NF1 and spontaneous pneumothorax is not widely recognised among clinicians. Here, we report the second case of recurring spontaneous pneumothorax in the context of NF1 with a confirmed molecular diagnosis. In both cases, the NF1 variants featured a premature stop codon in the C-terminal protein domain...

Ornithine transcarbamylase deficiency (OTCD) is a rare, X linked disorder that can manifest in late adulthood in heterozygous females as severe hyperammonaemia following environmental stressors. We present a case of hyperammonaemic encephalopathy that was triggered by glucocorticoid administration in an adult woman with heterozygous OTCD with clinical response to haemodialysis, ammonia scavengers and a high-calorie, low-protein diet.

A woman in her 60s was diagnosed with a metastatic, unresectable rare histological type of liver cancer; combined hepatocellular cholangiocarcinoma. She had palliative chemotherapy, initially with gemcitabine and cisplatin, and then with oxaliplatin, L-folinic acid and fluorouracil. Both treatment strategies demonstrated disease progression, and somatic mutation profiling revealed no actionable mutations. The patient was started on immuno-oncology (IO) with nivolumab and ipilimumab, followed by maintenance nivolumab...

We present the case of a pregnant woman in her 20s who presented in her second trimester with severe pulmonary haemorrhage and dialysis-dependent acute kidney failure due to antiglomerular basement membrane (GBM) disease. Responding to therapy, she recovered kidney function and delivered a baby. During her pregnancy, she developed cytomegalovirus viraemia, gestational diabetes and pre-eclampsia. Here, we report the first combined use of cyclophosphamide, rituximab and intensified plasma exchange in anti-GBM disease in pregnancy, allowing minimal exposure to cytotoxic medication, resulting in live birth and dialysis independence...

A jejunal diverticular haemorrhage is the second most common complication of jejunum diverticula. It can manifest clinically as acute upper gastrointestinal bleeding and is common to imitate acute rectal bleeding. Bleeding is usually associated with or without haemodynamic stability. Its diagnosis is challenging, requiring imaging examinations. Treatment is conservative management or surgery.

This case describes a rare occurrence of high anion gap metabolic acidosis due to chronic acetaminophen (paracetamol) usage, which can be confirmed by measuring 5-oxoproline (pyroglutamate), an organic acid metabolite. As acetaminophen is an extremely common drug prescribed in both inpatient and outpatient settings, a high degree of clinical suspicion is required to isolate it as the aetiology for metabolic acidosis. Management includes discontinuation of acetaminophen use and at times the supplementation of oral bicarbonate...

A woman in her late 50s presented to the ophthalmology clinic having bilateral eye pain and discharge for the last month. Her medical history was significant for lung adenocarcinoma, for which she was being treated with nivolumab. Filamentary keratitis was evident at the slit-lamp examination. Regardless of ophthalmic reasons, nivolumab was suspended. Prednisolone ointment was started, with a complete remission. We present a case of steroid-responsive filamentary keratitis triggered by nivolumab. We aim to highlight the importance of prompt ophthalmology referral and the use of therapies targeting ocular surface inflammation in immune checkpoint inhibition therapy...

A man in his 30s came to our clinic with a year-long history of progressive pain and swelling in his knee. Diagnostic imaging revealed a displaced patellar fracture with an osteolytic, septated lesion and thinned expanded cortex in both fracture fragments. A core needle biopsy confirmed the diagnosis of giant cell tumour. Treatment involved wide excision of the tumour and the use of polypropylene mesh and a peroneal longus tendon autograft to reconstruct the extensor mechanism of the knee joint. One year postoperatively, the patient experienced no pain, demonstrated full range of motion and showed no signs of functional impairment or local tumour recurrence...

A middle-aged man with progressive multifocal leukoencephalopathy (PML) in a human T-cell lymphotropic virus type-1 (HTLV-1) carrier on haemodialysis presented with mild dysarthria and ataxia. Brain MRI revealed asymmetric T2 -hyperintense lesions in the cerebral white matter, cerebellum and brainstem. A small amount of JC virus (JCV) genome in cerebrospinal fluid was detected by PCR and cerebellar biopsy demonstrated JCV-DNA presence. Pathological findings showed demyelinating lesions and glial cells with mildly enlarged nuclei, accompanied by T-lymphocytes, neutrophils and plasma cell infiltration...
